                         POOLING AND SERVICING AGREEMENT

            This Pooling and Servicing Agreement (the "Agreement") is dated and
effective as of August 1, 2005, among WACHOVIA COMMERCIAL MORTGAGE SECURITIES,
INC., as Depositor, WACHOVIA BANK, NATIONAL ASSOCIATION, as Master Servicer,
CWCAPITAL ASSET MANAGEMENT LLC, as Special Servicer, LASALLE BANK NATIONAL
ASSOCIATION, as Trustee and ABN AMRO BANK N.V., as Fiscal Agent.

                             PRELIMINARY STATEMENT:

            The Depositor intends to sell mortgage pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes
(each, a "Class"), which in the aggregate will evidence the entire beneficial
ownership interest in a trust fund (the "Trust Fund") to be created hereunder,
the primary assets of which will be the Mortgage Loans.

                                     REMIC I

            As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of all of the Mortgage Loans (exclusive of that
portion of the interest payments thereon that constitutes Additional Interest)
and certain other related assets subject to this Agreement as a REMIC for
federal income tax purposes, and such segregated pool of assets will be
designated as REMIC I. The Class R-I Certificates will represent the sole class
of "residual interests" in REMIC I for purposes of the REMIC Provisions under
federal income tax law.

                                    REMIC II

            As provided herein, the Trustee will elect to treat the segregated
pool of assets consisting of all of the REMIC I Regular Interests as a REMIC for
federal income tax purposes, and such segregated pool of assets will be
designated as REMIC II. The Class R-II Certificates will evidence the sole class
of "residual interests" in REMIC II for purposes of the REMIC Provisions under
federal income tax law. For federal income tax purposes, each Class of the
Regular Certificates (other than the obligation of the Class X-C Certificates to
make any Class A-MFL Swap Counterparty Special Payment), the Class A-3SF Regular
Interest and the Class A-MFL Regular Interest will be designated as a separate
"regular interest" in REMIC II for purposes of the REMIC Provisions under
federal income tax law.

            The following table sets forth the Class or Component designation,
the original REMIC I Principal Balance for each corresponding REMIC I Regular
Interest (the "Corresponding REMIC I Regular Interest"), the Corresponding
Components of the Class X Certificates (the "Corresponding Components") and the
Original Class Principal Balance for each Class of Sequential Pay Certificates
(the "Corresponding Certificates").

Z Certificates represent undivided beneficial interests in such Additional
Interest Grantor Trust. The Class A-3SF Regular Interest, the Class A-3SF Swap

Swap Contract, the Class A-MFL Floating Rate Account and the proceeds thereof
shall be treated as another grantor trust (the "Class A-MFL Grantor Trust") for
federal income tax purposes. The Class A-3SF Certificates and the Class A-MFL
Certificates represent undivided beneficial interests in the Class A-3SF Grantor
Trust and the Class A-MFL Grantor Trust, respectively. As provided herein, the
Trustee shall take all actions necessary to ensure that the portions of the
Trust Fund consisting of the Grantor Trusts maintain their respective status as

Serviced Mortgage Loan; provided, further, however that a Mortgage Loan or
Companion Loan will cease to be a Specially Serviced Mortgage Loan:

                  (i) with respect to the circumstances described in clause (a)
            above, when the related Mortgagor has made three consecutive full

            or Companion Loan (as such terms may be changed or modified in
            connection with a bankruptcy or similar proceeding involving the

            (c) and (g) above, when such default is cured; and

                  (iv) with respect to the circumstances described in clause (h)
            above, when such proceedings are terminated;

so long as at that time no circumstance identified in clauses (a) through (h)
above exists that would cause the Mortgage Loan (or, with respect to a Co-Lender
Loan, the related Companion Loan, or, with respect to a Companion Loan, the
related Co-Lender Loan) to continue to be characterized as a Specially Serviced
Mortgage Loan; provided no additional default is foreseeable in the reasonable
good faith judgment of the Special Servicer.

Loan as of the date of the related REO Acquisition, minus (y) the sum of:

                  on or before such date of determination.

            A Mortgage Loan or an REO Loan shall be deemed to be part of the
Trust Fund and to have an outstanding Stated Principal Balance until the
Distribution Date on which the payments or other proceeds, if any, received in
connection with a Liquidation Event in respect thereof are to be (or, if no such
payments or other proceeds are received in connection with such Liquidation
Event, would have been) distributed to Certificateholders. In addition, to the
extent that principal from general collections is used to reimburse
Nonrecoverable Advances pursuant to Section 3.05(a)(vii) or Workout Delayed

Principal Distribution Amount for purposes of clauses (i), (ii) and (iii) above.
Notwithstanding the foregoing, if any Mortgage Loan is paid in full, liquidated
or otherwise removed from the Trust Fund, commencing as of the first
Distribution Date following the Collection Period during which such event
occurred, the Stated Principal Balance of such Mortgage Loan will be zero.

            "Workout-Delayed Reimbursement Amounts": With respect to any
Mortgage Loan, the amount of any Advance made with respect to such Mortgage Loan
on or before the date such Mortgage Loan becomes (or, but for the making of

reimbursed to the Person who made such Advance on or before the date, if any, on
which such Mortgage Loan becomes a Corrected Mortgage Loan (or, with respect to
the 2005-C19 Serviced Mortgage Loan, a "corrected mortgage loan" under the
2005-C19 Pooling and Servicing Agreement, or, with respect to the LB-UBS 2005-C3

of time rather than immediately or on the next Due Date under the terms of the
modified loan documents.

            "Workout Fee": With respect to each Corrected Mortgage Loan, the fee

1.0%.

            "Yield Maintenance Charge": Payments paid or payable, as the context
requires, on a Mortgage Loan as the result of a Principal Prepayment thereon,
not otherwise due thereon in respect of principal or interest, which have been
calculated (based on Scheduled Payments on such Mortgage Loan) to compensate the
holder for reinvestment losses based on the value of an interest rate index at
or near the time of prepayment. Any other prepayment premiums, penalties and
fees not so calculated will not be considered "Yield Maintenance Charges." In
the event that a Yield Maintenance Charge shall become due for any particular
Mortgage Loan, the Master Servicer shall be required to follow the terms and
provisions contained in the applicable Mortgage Note; provided, however, in the
event the particular Mortgage Note shall not specify the U.S. Treasuries which
shall be used in determining the discount rate or the reinvestment yield to be
applied in such calculation, the Master Servicer shall be required to use those
U.S. Treasuries having maturity dates most closely approximating the maturity of
such Mortgage Loan. Accordingly if either no U.S. Treasury issue, or more than
one U.S. Treasury issue, shall coincide with the term over which the Yield
Maintenance Charge shall be calculated (which depending on the applicable
Mortgage Note is based on the remaining average life of the Mortgage Loan or the
actual term remaining through the Maturity Date), the Master Servicer shall use
the U.S. Treasury whose reinvestment yield is the lowest, with such yield being
based on the bid price for such issue as published in The Wall Street Journal on
the date that is fourteen (14) days prior to the date that the Yield Maintenance
Charge shall become due and payable (or, if such bid price is not published on
that date, the next preceding date on which such bid price is so published) and
converted to a monthly compounded nominal yield. The monthly compounded nominal
yield ("MEY") is derived from the reinvestment yield or discount rate and shall
be defined as MEY = (12X {(1+"BEY"/2)^1/6}-1) where BEY is defined as the U.S.
Treasury Reinvestment Yield which is in decimal form and not in percentage, and
1/6 is the exponential power to which a portion of the equation is raised. For
example, using a BEY of 5.50%, the MEY = (12 X {(1+ .055/2)^0.16667}-1) where
0.055 is the decimal version of the percentage 5.5% and 0.16667 is the decimal
version of the exponential power. The MEY in the above calculation is 5.44%.

            (a) The Depositor, concurrently with the execution and delivery
hereof, does hereby assign, sell, transfer, set over and otherwise convey to the
Trustee, in trust, without recourse, for the benefit of the Certificateholders
(and for the benefit of the other parties to this Agreement as their respective
interests may appear) all the right, title and interest of the Depositor, in, to
and under (i) the Mortgage Loans and all documents included in the related
Mortgage Files and Servicing Files, (ii) the rights of the Depositor under
Sections 2, 3, 9, 10, 11, 12, 13, 14, 16, 17, 18 and 19 of each of the Mortgage
Loan Purchase Agreements and, (iii) all other assets included or to be included
in the Trust Fund. Such assignment includes all interest and principal received
or receivable on or with respect to the Mortgage Loans and due after the Cut-Off
Date (except, with respect to those Mortgage Loans that were closed in July 2005
but have their first Due Date in August 2005, any interest amounts relating to
the period prior to the Cut-off Date). The transfer of the Mortgage Loans and
the related rights and property accomplished hereby is absolute and,
notwithstanding Section 11.07, is intended by the parties to constitute a sale.

            (b) In connection with the Depositor's assignment pursuant to
Section 2.01(a) above the Depositor shall direct, and hereby represents and
warrants that it has directed, each Mortgage Loan Seller pursuant to the
applicable Mortgage Loan Purchase Agreement, to deliver to and deposit with, or
cause to be delivered to and deposited with, the Trustee or a Custodian
appointed thereby (with a copy to the Master Servicer and Special Servicer), on
or before the Closing Date, the Mortgage File for each Mortgage Loan so assigned
and the Servicing File to the Master Servicer. The Special Servicer may request
the Master Servicer to deliver a copy of the Servicing File for any Mortgage
Loan (other than a Specially Serviced Mortgage Loan, which will not be at the
expense of the Special Servicer) at the expense of the Special Servicer. None of
the Trustee, any Custodian, the Master Servicer or the Special Servicer shall be
liable for any failure by any Mortgage Loan Seller or the Depositor to comply
with the document delivery requirements of the applicable Mortgage Loan Purchase
Agreement and this Section 2.01(b).

            (c) If any Mortgage Loan Seller cannot deliver, or cause to be
delivered, on the Closing Date, as to any Mortgage Loan, any of the documents
and/or instruments referred to in clauses (ii), (iii), (vi) (if recorded) and
(viii) of the definition of "Mortgage File," with evidence of recording thereon,
solely because of a delay caused by the public recording office where such
document or instrument has been delivered for recordation, the delivery
requirements of the related Mortgage Loan Purchase Agreement and Section 2.01(b)
shall be deemed to have been satisfied as to such non-delivered document or
instrument, and such non-delivered document or instrument shall be deemed to
have been included in the Mortgage File; provided that a photocopy of such
non-delivered document or instrument (certified by the applicable Mortgage Loan
Seller to be a true and complete copy of the original thereof submitted for
recording) is delivered to the Trustee or a Custodian appointed thereby on or
before the Closing Date, and either the original of such non-delivered document
or instrument, or a photocopy thereof, with evidence of recording thereon, is
delivered to the Trustee or such Custodian within 120 days of the Closing Date
(or within such longer period after the Closing Date as the Trustee may consent
to, which consent shall not be unreasonably withheld so long as the applicable
Mortgage Loan Seller is, in good faith, attempting to obtain from the
appropriate county recorder's office such original or photocopy). If the
applicable Mortgage Loan Seller cannot deliver, or cause to be delivered, as to
any Mortgage Loan, any of the documents and/or instruments referred to in
clauses (ii), (iii), (vi) (if recorded) and (viii) of the definition of
"Mortgage File" (or, with respect to the Non-Serviced Mortgage Loans, a
photocopy thereof), with evidence of recording thereon, for any other reason,
including, without limitation, that such non-delivered document or instrument
has been lost, the delivery requirements of the applicable Mortgage Loan
Purchase Agreement and Section 2.01(b) shall be deemed to have been satisfied as
to such non-delivered document or instrument and such non-delivered document or
instrument shall be deemed to have been included in the Mortgage File; provided
that a photocopy of such non-delivered document or instrument (with evidence of
recording thereon) is delivered to the Trustee or a Custodian appointed thereby
on or before the Closing Date.

            If, on the Closing Date as to any Mortgage Loan, the applicable
Mortgage Loan Seller does not deliver in complete and recordable form any one of
the assignments in favor of the Trustee referred to in clause (iv) or (v) of the
definition of "Mortgage File" (or, with respect to the Non-Serviced Mortgage
Loans, a photocopy thereof), the applicable Mortgage Loan Seller may
provisionally satisfy the delivery requirements of the related Mortgage Loan
Purchase Agreement and Section 2.01(b) by delivering with respect to such
Mortgage Loan on the Closing Date an omnibus assignment of such Mortgage Loan;
provided that all required original assignments with respect to such Mortgage
Loan in fully complete and recordable form shall be delivered to the Trustee or
its Custodian within 120 days of the Closing Date (or within such longer period
as the Trustee in its discretion may permit).

            (d) The Trustee shall, for a fee paid to the Trustee by the
Depositor on the Closing Date as to each Mortgage Loan (other than the
Non-Serviced Mortgage Loans), promptly (and in any event within 90 days
following the latest of (i) the Closing Date, (ii) the delivery of all
assignments and UCC Financing Statements to the Trustee and (iii) the date on
which the Trustee receives, with respect to the original recorded or filed
documents relating to such assignments and UCC Financing Statements, all
necessary recording and filing information required for the recording or filing
of such assignments and UCC Financing Statements) cause to be submitted for
recording or filing, as the case may be, in the appropriate public office for
real property records or UCC Financing Statements, as appropriate and to the
extent timely delivered to the Trustee in final, recordable form, each
assignment of Mortgage, assignment of Assignment of Leases and any other
recordable documents (to the extent the Trustee has actual knowledge that such
documents are to be recorded) relating to each such Mortgage Loan, in favor of
the Trustee referred to in clause (iv)(a), (b) and (c), respectively, of the
definition of "Mortgage File" and each UCC-2 and UCC-3 assignment in favor of
the Trustee and so delivered to the Trustee and referred to in clause (viii) of
the definition of "Mortgage File." The applicable Mortgage Loan Seller shall
reimburse the Trustee for all reasonable costs and expenses incurred for
recording any documents described in clause (iv)(c) of the definition of
"Mortgage File." Each such assignment, UCC-2 and UCC-3 shall reflect that the
recorded original should be returned by the public recording office to the
Trustee or its designee following recording, and each such UCC-2 and UCC-3
assignment shall reflect that the file copy thereof should be returned to the
Trustee or its designee following filing; provided that in those instances where
the public recording office retains the original assignment of Mortgage or
assignment of Assignment of Leases, the Trustee shall obtain therefrom a
certified copy of the recorded original, at the expense of the Depositor. If any
such document or instrument is lost or returned unrecorded or unfiled, as the
case may be, because of a defect therein, the Trustee shall direct the related
Mortgage Loan Seller pursuant to the applicable Mortgage Loan Purchase Agreement
to promptly prepare or cause to be prepared a substitute therefor or cure such
defect, as the case may be, and thereafter the Trustee shall upon receipt
thereof cause the same to be duly recorded or filed, as appropriate. Upon
request, the Trustee shall forward to the Master Servicer a copy of each of the
aforementioned recorded assignments following the Trustee's receipt thereof, to
the extent not previously provided.

            (e) All documents and records in the Servicing File in possession of
the Depositor or the Mortgage Loan Sellers (except attorney client privileged
communications, draft documents and any documents or materials prepared by the
Mortgage Loan Sellers or their Affiliates for internal uses, including, without
limitation, internal correspondence and credit analysis of the Mortgage Loan
Sellers) that relate to the Mortgage Loans (other than the Non-Serviced Mortgage
Loans) and that are not required to be a part of a Mortgage File in accordance
with the definition thereof (including any original letters of credit), together
with all Escrow Payments and Reserve Accounts in the possession thereof, shall
be delivered to the Master Servicer or such other Person as may be directed by
the Master Servicer (at the expense of the applicable Mortgage Loan Seller) on
or before the Closing Date and shall be held by the Master Servicer on behalf of
the Trustee in trust for the benefit of the Certificateholders; provided,
however, the Master Servicer shall have no responsibility for holding documents
created or maintained by the Special Servicer hereunder and not delivered to the
Master Servicer.

            (f) In connection with the Depositor's assignment pursuant to
Section 2.01(a) above, the Depositor shall deliver to the Custodian and the
Master Servicer on or before the Closing Date and hereby represents and warrants
that it has delivered a copy of a fully executed counterpart of each Mortgage
Loan Purchase Agreement, as in full force and effect on the Closing Date.

            Section 2.02 Acceptance of the Trust Fund by Trustee.

            (a) The Trustee, by its execution and delivery of this Agreement,
acknowledges receipt of the Depositor's assignment to it of the Depositor's
right, title and interest in the assets that constitute the Trust Fund, and
further acknowledges receipt by it or a Custodian on its behalf, subject to the
provisos in the definition of "Mortgage File" and the provisions of Section 2.01
and subject to the further limitations on review provided for in Section 2.02(b)
and the exceptions noted on the schedule of exceptions of (i) the Mortgage File
delivered to it for each Mortgage Loan and (ii) a copy of a fully executed
counterpart of each Mortgage Loan Purchase Agreement, all in good faith and
without notice of any adverse claim, and declares that it or a Custodian on its
behalf holds and will hold such documents and the other documents received by it
that constitute portions of the Mortgage Files, and that it holds and will hold
the Mortgage Loans and other assets included in the Trust Fund, in trust for the
exclusive use and benefit of all present and future Certificateholders and, with
respect to any original document in the Mortgage File for a Loan Pair, any
present or future Companion Holders. The Trustee hereby certifies to each of the
Depositor, the Master Servicer, the Special Servicer and each Mortgage Loan
Seller that except as identified in the schedule of exceptions, which is
attached hereto as Exhibit C-1 without regard to the proviso in the definition
of "Mortgage File," each of the original executed Mortgage Notes (or lost note
affidavit), the Mortgage (or an executed copy thereof), the lender's title
policy (original or copy or marked-up title commitment marked as binding and
countersigned by the title company or its authorized agent or an agreement to
provide the same pursuant to binding escrow instructions executed by an
authorized representative of the title company), a copy of any related Ground
Leases, the original (or copy if the original has been delivered to the Master
Servicer) of any related letters of credit (and the related transfer or
assignment documents, if applicable), as described in clauses (i), (ii), (vii),
(ix)(a) and (xii), respectively, of the definition of Mortgage File are in its
possession.

            With respect to the schedule of exceptions described in the
preceding paragraph, within fifteen (15) Business Days (or, in the Controlling
Class Representative's reasonable discretion, thirty (30) Business Days) of the
Closing Date, with respect to the documents specified in clauses (i), (ii),
(vii), (ix) (solely with respect to Ground Leases) and (xii) of the definition
of Mortgage File, the related Mortgage Loan Seller shall cure any material
exception listed therein (for the avoidance of doubt, any deficiencies with
respect to the documents specified in clause (ii) resulting solely from a delay
in the return of the related documents from the applicable recording office,
shall be cured in the time and manner described in Section 2.01(c)). If such
exception is not so cured, the related Mortgage Loan Seller shall either (1)
repurchase the related Mortgage Loan, (2) with respect to exceptions relating to
clause (xii) of the definition of "Mortgage File", deposit with the Paying Agent
(who shall promptly notify the Master Servicer thereof) an amount, to be held in
a Special Reserve Account, equal to the amount of the undelivered letter of
credit (in the alternative, the related Mortgage Loan Seller may deliver to the
Paying Agent, with a certified copy to the Master Servicer and Trustee, a letter
of credit for the benefit of the Master Servicer on behalf of the Trustee and
upon the same terms and conditions as the undelivered letter of credit) which
the Master Servicer on behalf of the Trustee may use (or draw upon, as the case
may be) under the same circumstances and conditions as the Master Servicer would
have been entitled to draw on the undelivered letter of credit, or (3) with
respect to any exceptions relating to clauses (i), (ii) and (vii), deposit with
the Paying Agent on behalf of the Trustee an amount, to be held in trust in a
Special Reserve Account, equal to 25% of the Stated Principal Balance of the
related Mortgage Loan. Any letter of credit or funds deposited pursuant to
clauses (2) and (3) shall be held pursuant to the related Mortgage Loan Purchase
Agreement by the Paying Agent until the earlier of (x) the date on which the
Master Servicer certifies to the Trustee and the Controlling Class
Representative that such exception has been cured (or the Trustee certifies the
same to the Controlling Class Representative), at which time such funds or
letter of credit, as applicable, shall be returned to the related Mortgage Loan
Seller and (y) thirty (30) Business Days or, if the Controlling Class
Representative extends the Cure Period, forty-five (45) Business Days after the
Closing Date; provided, however, that if such exception is not cured within such
thirty (30) Business Days or forty-five (45) Business Days, as the case may be,
(A) in the case of clause (2), the Paying Agent shall retain such funds on
deposit in the related Special Reserve Account, or (B) in the case of clause
(3), the related Mortgage Loan Seller shall repurchase the related Mortgage Loan
in accordance with the terms and conditions of Section 2.03(b) or the related
Mortgage Loan Purchase Agreement, at which time such funds shall be applied to
the Purchase Price of the related Mortgage Loan.

            (b) In addition, within ninety (90) days after the Closing Date (and
if any exceptions are noted, a schedule of exceptions again every 90 days
thereafter until the second anniversary of the Closing Date, and a schedule of
exceptions every 180 days thereafter until the fifth anniversary of the Closing
Date, and thereafter upon request by any party hereto, any Mortgage Loan Seller
or the Majority Subordinate Certificateholder), the Trustee or the Custodian on
its behalf will review the Mortgage Files and certify (in a certificate
substantially in the form of Exhibit C-2) to each of the Depositor, the Master
Servicer, the Special Servicer and each Mortgage Loan Seller (with copies to the
Majority Subordinate Certificateholder) that, with respect to each Mortgage Loan
(and with respect to a Companion Loan, the 2005-C19 Serviced Mortgage Loan, the
LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage
Loan, only those items required pursuant to the definition of "Mortgage File")
listed in the Mortgage Loan Schedule, except as specifically identified in the
schedule of exceptions annexed thereto, (i) without regard to the proviso in the
definition of "Mortgage File," all documents specified in clauses (i), (ii),
(iv)(a), (v) and (vii), and to the extent provided in the related Mortgage File
and actually known by a Responsible Officer of the Trustee to be required,
clauses (iii), (iv)(b), (iv)(c), (vi), (viii), (ix)(a) and (xii) of the
definition of "Mortgage File" are in its possession, (ii) all documents
delivered or caused to be delivered by the applicable Mortgage Loan Seller
constituting the related Mortgage File have been reviewed by it and appear
regular on their face and appear to relate to such Mortgage Loan, (iii) based on
such examination and only as to the foregoing documents, the information set
forth in the Mortgage Loan Schedule for such Mortgage Loan with respect to the
items specified in clauses (v) and (vi)(c) of the definition of "Mortgage Loan
Schedule" is correct and (iv) solely with respect to the Companion Loans, all
documents specified in clause (xiii) of the definition of Mortgage File are in
its possession. Further, with respect to the documents described in clause
(viii) of the definition of Mortgage File, the Trustee may assume, for purposes
of the certification delivered in this Section 2.02(b) and for purposes of
determining (subject to the proviso at the end of this sentence) where to file
UCC Financing Statements, that the related Mortgage File should include one
state level UCC Financing Statement filing in the state of incorporation of the
Mortgagor for each Mortgaged Property (or with respect to any Mortgage Loan that
has two or more Mortgagors, for each Mortgagor); provided, however, that to the
extent the Trustee has actual knowledge or is notified of any fixture or real
property UCC Financing Statements filed in the county of the state where the
related Mortgaged Property is located, the Trustee shall file an assignment to
the Trust Fund with respect to such UCC Financing Statements in the appropriate
jurisdiction under the UCC at the expense of the related Mortgage Loan Seller.
The UCC Financing Statements to be assigned to the Trust Fund pursuant to
Section 2.01(d) will be delivered by the related Mortgage Loan Seller to the
Trustee on the new national forms, in recordable form and completed pursuant to
Revised Article IX of the UCC. The Trustee will submit such UCC Financing
Statements for filing in the state of incorporation of the related Mortgagor as
so indicated on the documents provided.

            (c) None of the Trustee, the Master Servicer, the Special Servicer
or any Custodian is under any duty or obligation to inspect, review or examine
any of the documents, instruments, certificates or other papers relating to the
Mortgage Loans delivered to it to determine that the same are valid, legal,
effective, genuine, enforceable, in recordable form, sufficient or appropriate
for the represented purpose or that they are other than what they purport to be
on their face.

            (d) The Trustee may establish a Special Reserve Account which shall
be an Eligible Account, and the Trustee or its designee shall deposit any amount
required to be deposited in a Special Reserve Account within one Business Day of
receipt. The related Mortgage Loan Seller may direct the Trustee to invest or
cause the investment of the funds deposited in the Special Reserve Account in
Permitted Investments that bear interest or are sold at a discount and that
mature, unless payable on demand, no later than the Business Day prior to the
next P&I Advance Date. The Trustee shall act upon the written instructions of
the Mortgage Loan Seller with respect to the investment of the funds in the
Special Reserve Account in such Permitted Investments; provided that in the
absence of appropriate and timely written instructions from the related Mortgage
Loan Seller, the Trustee shall not have any obligation to invest or direct the
investment funds in such Special Reserve Account. All income and gain realized
from the investment of funds deposited in such Special Reserve Account shall be
for the benefit of the related Mortgage Loan Seller and shall be withdrawn by
the Trustee or its designees and remitted to the related Mortgage Loan Seller on
each P&I Advance Date (net of any losses incurred), and the related Mortgage
Loan Seller shall remit to the Trustee from the related Mortgage Loan Seller's
own funds for deposit into such Special Reserve Account the amount of any Net
Investment Loss (net of Net Investment Earnings) in respect of such Permitted
Investments immediately upon realization of such Net Investment Losses and
receipt of written notice thereof from the Trustee; provided that the Mortgage
Loan Seller shall not be required to deposit any loss on an investment of funds
in the Special Reserve Account if such loss is incurred solely as a result of
the insolvency of the federal or state chartered depository institution or trust
company that holds such Special Reserve Account; provided that such depository
institution is not the same entity as such Mortgage Loan Seller. The Special
Reserve Account shall be considered an "outside reserve fund" within the meaning
of the REMIC Provisions, and such Special Reserve Account (or any reimbursement
from REMIC I or REMIC II with respect thereto) will be beneficially owned by the
Mortgage Loan Seller, who shall be taxable on all income, if any, with respect
thereto.

            (e) With respect to exceptions related to clause (xii) of the
definition of "Mortgage File" and any cash or substitute letters of credit held
by the Trustee in the Special Reserve Account from time to time, if
circumstances arise in servicing the related Mortgage Loan such that the Master
Servicer or Special Servicer, as the case may be, is entitled to draw upon the
undelivered letter of credit, the Master Servicer or Special Servicer, as the
case may be, shall present an Officer's Certificate to the Trustee requesting
that the cash or substitute letter of credit held in the Special Reserve
Account, be remitted or released, as the case may be, and the Trustee shall
remit such cash or release such substitute letter of credit within one (1)
Business Day of receipt of such Officer's Certificate. Upon release of any
substitute letter of credit to the Master Servicer or Special Servicer, the
Trustee shall no longer be responsible for such letter of credit.

            Section 2.03 Mortgage Loan Seller's Repurchase or Substitution of
Mortgage Loans for Document Defects and Breaches of Representations and
Warranties.

            (a) If any party hereto discovers or receives notice that any
document or documents constituting a part of a Mortgage File (including that
part relating to the AmericasMart Loan, the 101 Avenue of the Americas Loan and
the U-Haul Portfolio Loan to be held by the 2005-C19 Trustee, the LB-UBS 2005-C3
Trustee and the MSCI 2005-HQ6 Trustee, respectively) has not been properly
executed, is missing (beyond the time period required for its delivery
hereunder), contains information that does not conform in any material respect
with the corresponding information set forth in the Mortgage Loan Schedule, or
does not appear to be regular on its face (each a "Document Defect"), or
discovers or receives notice of a breach of any representation or warranty
relating to any Mortgage Loan set forth in the applicable Mortgage Loan Purchase
Agreement (a "Breach"), the party discovering such Document Defect or Breach
shall give written notice (which notice, in respect of any obligation of the
Trustee to provide notice of a Document Defect, shall be deemed given by the
delivery of the certificate as required by Section 2.02(a)) to the other parties
hereto, to the Majority Subordinate Certificateholder and to the Rating Agencies
of such Document Defect or Breach. Promptly upon becoming aware of any Document
Defect or Breach (including through such written notice provided by any party
hereto or the Majority Subordinate Certificateholder as provided above), if any
party hereto determines that such Document Defect or Breach materially and
adversely affects the value of the affected Mortgage Loan, the interest of the
Trust therein or the interests of any Certificateholder, such party shall notify
the Master Servicer of such determination and promptly after receipt of such
notice, the Master Servicer shall request in writing (with a copy to the other
parties hereto, the Majority Subordinate Certificateholder, the Rating Agencies
and the Controlling Class Representative (if different from the Majority
Subordinate Certificateholder)) that the applicable Mortgage Loan Seller, not
later than ninety (90) days from receipt of such written request (or, in the
case of a Document Defect or Breach relating to a Mortgage Loan not being a
"qualified mortgage" within the meaning of the REMIC Provisions, not later than
ninety (90) days after any party to this Agreement discovers such Document
Defect or Breach) (i) cure such Document Defect or Breach, as the case may be,
in accordance with Section 3(c) of the applicable Mortgage Loan Purchase
Agreement, (ii) repurchase the affected Mortgage Loan in accordance with Section
3(c) of the related Mortgage Loan Purchase Agreement, or (iii) within two years
of the Closing Date, substitute a Qualified Substitute Mortgage Loan for such
affected Mortgage Loan and pay the Master Servicer for deposit into the
Certificate Account any Substitution Shortfall Amount in connection therewith in
accordance with Sections 3(c) and 3(d) of the applicable Mortgage Loan Purchase
Agreement; provided, however, that if such Document Defect or Breach is capable
of being cured, but not within such ninety (90) day period, such Document Defect
or Breach does not relate to the Mortgage Loan not being treated as a "qualified
mortgage" within the meaning of the REMIC Provisions, and the applicable
Mortgage Loan Seller has commenced and is diligently proceeding with the cure of
such Document Defect or Breach within such ninety (90) day period, the
applicable Mortgage Loan Seller shall have an additional ninety (90) days to
complete such cure (or, failing such cure, to repurchase the related Mortgage
Loan); provided, further, with respect to such additional ninety (90) day period
the applicable Mortgage Loan Seller shall have delivered an Officer's
Certificate to the Trustee setting forth what actions the applicable Mortgage
Loan Seller is pursuing in connection with the cure thereof and stating that the
applicable Mortgage Loan Seller anticipates such Document Defect or Breach will
be cured within the additional ninety (90) day period; provided, further, that
no Document Defect (other than with respect to a Mortgage Note, Mortgage, title
insurance policy, Ground Lease, any letter of credit, franchise agreement or any
comfort letter and comfort letter transfer documents (collectively, the
"Material Core Documents")) shall be considered to materially and adversely
affect the interests of any Certificateholder, the interest of the Trust therein
or the value of the related Mortgage Loan unless the document with respect to
which the Document Defect exists is required in connection with an imminent
enforcement of the mortgagee's rights or remedies under the related Mortgage
Loan, defending any claim asserted by any borrower or third party with respect
to the Mortgage Loan, establishing the validity or priority of any lien on any
collateral securing the Mortgage Loan or for any immediate significant servicing
obligations; provided, further, with respect to Document Defects which
materially and adversely affect the interest of any Certificateholder, the
interests of the Trust therein or the value of the related Mortgage Loan, other
than with respect to Document Defects relating to the Material Core Documents,
any applicable cure period following the initial ninety (90) day cure period may
be extended by the Master Servicer or the Special Servicer if the document
involved is not needed imminently. Such extension will end upon 30 days notice
of such need as reasonably determined by the Master Servicer or Special Servicer
(with a possible 30 day extension if the Master Servicer or Special Servicer
agrees that the applicable Mortgage Loan Seller is diligently pursuing a cure).
Pursuant to the related Mortgage Loan Purchase Agreement, the related Mortgage
Loan Seller shall cure all Document Defects which materially and adversely
affect the interests of any Certificateholder, the interests of the Trust
therein or the value of the related Mortgage Loan, regardless of the document
involved, no later than two years following the Closing Date; provided, however,
that the initial ninety (90) day cure period referenced above shall not be
reduced. For a period of two years from the Closing Date, so long as there
remains any Mortgage File as to which there is any uncured Document Defect and
so long as the applicable Mortgage Loan Seller shall provide the Officer's
Certificate pursuant to Section 3(c) of the applicable Mortgage Loan Purchase
Agreement, the Trustee shall on a quarterly basis prepare and deliver to the
other parties a written report as to the status of such uncured Document Defects
as provided in this Section 2.03. If the affected Mortgage Loan is to be
repurchased or substituted, the Master Servicer shall designate the Certificate
Account as the account to which funds in the amount of the Purchase Price or the
Substitution Shortfall Amount, as applicable, are to be wired. Any such
repurchase or substitution of a Mortgage Loan shall be on a whole loan,
servicing released basis.

            If (i) any Mortgage Loan is required to be repurchased or
substituted for in the manner described in the immediately preceding paragraph,
(ii) such Mortgage Loan is a Crossed Loan, and (iii) the applicable Document
Defect or Breach does not constitute a Document Defect or Breach, as the case
may be, as to any other Crossed Loan in such Crossed Group (without regard to
this paragraph), then the applicable Document Defect or Breach, as the case may
be, will be deemed to constitute a Document Defect or Breach, as the case may
be, as to any other Crossed Loan in the Crossed Group for purposes of this
paragraph, and the related Mortgage Loan Seller will be required to repurchase
or substitute for such other Crossed Loan(s) in the related Crossed Group as
provided in the immediately preceding paragraph unless such other Crossed Loans
satisfy the Crossed Loan Repurchase Criteria and satisfy all other criteria for
substitution and repurchase of Mortgage Loans set forth herein. In the event
that the remaining Crossed Loans in such Crossed Group satisfy the
aforementioned criteria, the Mortgage Loan Seller may elect either to repurchase
or substitute for only the affected Crossed Loan as to which the related Breach
or Document Defect exists or to repurchase or substitute for all of the Crossed
Loans in the related Crossed Group. Any reserve or other cash collateral or
letters of credit securing the Crossed Loans shall be allocated between such
Mortgage Loans in accordance with the Mortgage Loan documents. All other terms
of the Mortgage Loans shall remain in full force and effect without any
modification thereof.

            With respect to any Crossed Loan, to the extent that the applicable
Mortgage Loan Seller is required to repurchase or substitute for such Mortgage
Loan in the manner prescribed in this Section 2.03(a) while the Trustee
continues to hold any other Crossed Loans in the related Crossed Group, the
applicable Mortgage Loan Seller and the Depositor will, as set forth in the
related Mortgage Loan Purchase Agreement (any expenses incurred by the Trustee
or the Master Servicer in connection with any modification or accommodation
referred to in such Mortgage Loan Purchase Agreement (including but not limited
to reasonable attorney fees) shall be paid by the related Mortgage Loan Seller),
forbear from enforcing any remedies against the other's Primary Collateral but
each will be permitted to exercise remedies against the Primary Collateral
securing its respective Mortgage Loans, including with respect to the Trustee,
the Primary Collateral securing Mortgage Loans still held by the Trustee.

            (b) In connection with any repurchase or substitution of one or more
Mortgage Loans contemplated by this Section 2.03, upon receipt of a Request for
Release (in the form of Exhibit D-1 attached hereto) of a Servicing Officer of
the Master Servicer certifying as to the receipt of the applicable Purchase
Price(s) in the Certificate Account (in the case of any such repurchase) or the
receipt of the applicable Substitution Shortfall Amount(s) in the Certificate
Account and upon the delivery of the Mortgage File(s) and the Servicing File(s)
for the related Qualified Substitute Mortgage Loan(s) to the Custodian and the
Master Servicer, respectively (in the case of any such substitution), (i) the
Trustee shall execute and deliver such endorsements and assignments as are
provided to it, in each case without recourse, representation or warranty, as
shall be necessary to vest in the applicable Mortgage Loan Seller the legal and
beneficial ownership of each repurchased Mortgage Loan or deleted Mortgage Loan,
as applicable, being released pursuant to this Section 2.03, and (ii) the
Trustee, the Custodian, the Master Servicer, and the Special Servicer shall each
tender to the applicable Mortgage Loan Seller, upon delivery to each of them of
a receipt executed by the applicable Mortgage Loan Seller, all portions of the
Mortgage File and other documents pertaining to each such Mortgage Loan
possessed by it and the Master Servicer and the Special Servicer shall release
to the applicable Mortgage Loan Seller any Escrow Payments and Reserve Funds
held by it in respect of such repurchased or deleted Mortgage Loan; provided
that such tender by the Trustee or the Custodian shall be conditioned upon its
receipt from the Master Servicer or the Special Servicer of a Request for
Release. Thereafter, the Trustee, the Custodian, the Master Servicer and the
Special Servicer shall have no further responsibility with regard to the related
repurchased Mortgage Loan(s) or deleted Mortgage Loan(s), as applicable, and the
related Mortgage File(s) and Servicing File(s). The Master Servicer shall, and
is hereby authorized and empowered by the Trustee to, prepare, execute and
deliver in its own name, on behalf of the Certificateholders and the Trustee or
any of them, the endorsements and assignments contemplated by this Section 2.03,
and the Trustee shall execute any powers of attorney that are prepared and
delivered to the Trustee by the Master Servicer and are necessary to permit the
Master Servicer to do so. The Master Servicer shall indemnify the Trustee for
any reasonable costs, fees, liabilities and expenses incurred by the Trustee in
connection with the negligent or willful misuse by the Master Servicer of such
powers of attorney. At the time a substitution is made, the related Mortgage
Loan Purchase Agreement will provide that the Mortgage Loan Seller shall deliver
the related Mortgage File to the Trustee and certify that the substitute
Mortgage Loan is a Qualified Substitute Mortgage Loan.

            (c) No substitution of a Qualified Substitute Mortgage Loan or Loans
may be made in any calendar month after the Determination Date for such month.
Periodic Payments due with respect to any Qualified Substitute Mortgage Loan
after the related date of substitution shall be part of REMIC I. Periodic
Payments due with respect to any Qualified Substitute Mortgage Loan on or prior
to the related date of substitution shall not be part of the Trust Fund or REMIC
I and will (to the extent received by the Master Servicer) be remitted by the
Master Servicer to the applicable Mortgage Loan Seller promptly following
receipt.

            (d) Each Mortgage Loan Purchase Agreement provides the sole remedies
available to the Certificateholders, or the Trustee on behalf of the
Certificateholders, respecting any Document Defect or Breach with respect to the
Mortgage Loans purchased by the Depositor thereunder.

            (e) The Trustee with the cooperation of the Special Servicer (in the
case of Specially Serviced Mortgage Loans) shall, for the benefit of the
Certificateholders, enforce the obligations of the Mortgage Loan Sellers under
Section 3 of the applicable Mortgage Loan Purchase Agreement.

            (f) Notwithstanding the foregoing, if there exists a Breach relating
to whether or not the Mortgage Loan documents or any particular Mortgage Loan
document requires the related Mortgagor to bear the costs and expenses
associated with any particular action or matter under such Mortgage Loan
document(s) with respect to matters described in Representations 23 and 43 of
the applicable Mortgage Loan Purchase Agreement, then the Master Servicer shall
(and the Special Servicer may) direct the related Mortgage Loan Seller in
writing to wire transfer to the Certificate Account, within 90 days of such
Mortgage Loan Seller's receipt of such direction, the amount of any such costs
and expenses borne by the Trust Fund that are the basis of such Breach. Upon its
making such deposit, the related Mortgage Loan Seller shall be deemed to have
cured such Breach in all respects. Provided such payment is made in full, this
paragraph describes the sole remedy available to the Certificateholders, the
Master Servicer, the Special Servicer, and the Trustee on their behalf regarding
any such Breach and the related Mortgage Loan Seller shall not be obligated to
repurchase the affected Mortgage Loan on account of such Breach or otherwise
cure such Breach. Amounts deposited in the Certificate Account pursuant to this
paragraph shall be used for the reimbursement or payment of costs related to
such Breach.

            (g) With respect to any Mortgage Loan which has become a Defaulted
Mortgage Loan under this Agreement or with respect to which the related
Mortgaged Property has been foreclosed and which is the subject of a repurchase
claim under the related Mortgage Loan Purchase Agreement, the Special Servicer
with the consent of the Controlling Class Representative shall notify the
related Mortgage Loan Seller in writing of its intention to sell such Defaulted
Mortgage Loan or REO Property at least 45 days prior to any such action. The
related Mortgage Loan Seller shall have 10 Business Days to determine whether or
not to consent to such sale. If the related Mortgage Loan Seller consents to
such sale or a court of competent jurisdiction determines that the related
Mortgage Loan Seller was liable under the related Mortgage Loan Purchase
Agreement to repurchase such Defaulted Mortgage Loan or REO Property then such
Mortgage Loan Seller shall be liable for the difference (if any) between the
price of the Mortgage Loan or REO Property as sold and the price which the
related Mortgage Loan Seller would have to pay if it repurchased such Defaulted
Mortgage Loan or REO Property. If the related Mortgage Loan Seller does not
consent to such sale, the Special Servicer shall contract with a Determination
Party as to the merits of such sale. If the related Determination Party
determines that such sale is in accordance with the Servicing Standard and the
provisions of this Agreement with respect to the sale of Defaulted Mortgage
Loans or REO Properties and subsequent to such a sale, a court of competent
jurisdiction determines that related Mortgage Loan Seller was liable under the
related Mortgage Loan Purchase Agreement and required to repurchase such
Defaulted Mortgage Loan or REO Property in accordance with the terms thereof,
then pursuant to the related Mortgage Loan Purchase Agreement, the related
Mortgage Loan Seller shall remit to the Special Servicer an amount equal to the
difference (if any) between the proceeds of the related action and the price at
which the related Mortgage Loan Seller would have been obligated to pay had the
related Mortgage Loan Seller repurchased such Defaulted Mortgage Loan or REO
Property in accordance with the terms of the related Mortgage Loan Purchase
Agreement including the costs related to contracting with the related
Determination Party. If the related Determination Party determines that the sale
of the related Defaulted Mortgage Loan or REO Property is not in accordance with
the Servicing Standard and the provision of this Agreement with respect to the
sale of Defaulted Mortgage Loans or REO Properties and the Special Servicer
subsequently sells such Mortgage Loan or REO Property, then the related Mortgage
Loan Seller shall not be liable for any such difference (nor any cost of
contracting with the Determination Party). In the event that (a) the Special
Servicer ignores the determination of the Determination Party and sells the
related Defaulted Mortgage Loan or REO Property and/or (b) a court of competent
jurisdiction determines that the related Mortgage Loan Seller is not obligated
to repurchase the related Defaulted Mortgage or REO Property, the costs of
contracting with the Determination Party will constitute an Additional Trust
Fund Expense. If the related Mortgage Loan Seller is required pursuant to the
related Mortgage Loan Purchase Agreement to remit the amounts set forth in this
Section 2.03(g), the Special Servicer shall designate the Certificate Account as
the account to which such funds shall be wired.

            Section 2.04 Representations and Warranties of Depositor.

            (a) The Depositor hereby represents and warrants to the Trustee, for

            (v) The Depositor is not in violation of, and its execution and
      delivery of this Agreement and its performance and compliance with the
      terms of this Agreement will not constitute a violation of, any law, any
      order or decree of any court or arbiter, or any order, regulation or
      demand of any federal, state or local governmental or regulatory
      authority, which violation, in the Depositor's good faith and reasonable

      financial condition of the Depositor;

      contemplated herein requires no regulatory approval, other than any such
      approvals as have been obtained, and is not subject to any bulk transfer
      or similar law in effect in any applicable jurisdiction;

            (vii) No litigation is pending or, to the best of the Depositor's
      knowledge, threatened against the Depositor that, if determined adversely
      to the Depositor, would prohibit the Depositor from entering into this
      Agreement or that, in the Depositor's good faith and reasonable judgment,
      is likely to materially and adversely affect either the ability of the
      Depositor to perform its obligations under this Agreement or the financial
      condition of the Depositor;

            (viii) Immediately prior to the transfer of the Mortgage Loans to
      the Trust Fund pursuant to this Agreement, (A) the Depositor had good and
      marketable title to, and was the sole owner and holder of, each Mortgage
      Loan; and (B) the Depositor has full right and authority to sell, assign
      and transfer the Mortgage Loans and all servicing rights pertaining
      thereto; and

            (ix) The Depositor is transferring the Mortgage Loans to the Trust
      Fund free and clear of any liens, pledges, charges and security interests.

            (b) The representations and warranties of the Depositor set forth in
Section 2.04(a) shall survive the execution and delivery of this Agreement and
shall inure to the benefit of the Persons for whose benefit they were made for
so long as the Trust Fund remains in existence. Upon discovery by any party
hereto of any breach of any of the foregoing representations and warranties, the
party discovering such breach shall give prompt written notice thereof to the
other parties.

                 ADMINISTRATION AND SERVICING OF THE TRUST FUND

            Section 3.01 Administration of the Mortgage Loans.

            (a) Each of the Master Servicer and the Special Servicer shall
service and administer the Mortgage Loans (other than the Non-Serviced Mortgage
Loans) and Companion Loans (other than the Non-Serviced Companion Loans) that
each is obligated to service and administer pursuant to this Agreement on behalf
of the Trustee, for the benefit of the Certificateholders and in the case of the
Companion Loans, the related Companion Holder, in accordance with any and all
applicable laws, the terms of this Agreement (and, with respect to a Loan Pair,
the related Intercreditor Agreement), the terms of the respective Mortgage
Loans, and, if applicable, the Companion Loans and, to the extent consistent
with the foregoing, in accordance with the Servicing Standard. With respect to
any Loan Pair, in the event of a conflict between this Agreement and the related
Intercreditor Agreement, the Intercreditor Agreement will control; provided that
in no event shall the Master Servicer or Special Servicer take any action or
omit to take any action in accordance with the terms of any Intercreditor
Agreement that would cause such servicer to violate the Servicing Standard or
the REMIC Provisions. Without limiting the foregoing, and subject to Section
3.21, (i) the Master Servicer shall service and administer all Mortgage Loans
and the Companion Loans (in each case, other than the Non-Serviced Mortgage
Loans and their related Companion Loans) that are not Specially Serviced
Mortgage Loans, and (ii) the Special Servicer shall service and administer each
Specially Serviced Mortgage Loan (other than the Non-Serviced Mortgage Loans and
their related Companion Loans) and REO Property and shall render such services
with respect to all Mortgage Loans, Companion Loans and REO Properties as are
specifically provided for herein; provided that the Master Servicer shall
continue to receive payments, make all calculations, and prepare, or cause to be
prepared, all reports required hereunder with respect to the Specially Serviced
Mortgage Loans, except for the reports specified herein as prepared by the
Special Servicer, as if no Servicing Transfer Event had occurred and with
respect to the REO Properties (and the related REO Loans) as if no REO
Acquisition had occurred, and to render such incidental services with respect to
such Specially Serviced Mortgage Loans and REO Properties as are specifically
provided for herein; provided, further, however, that the Master Servicer shall
not be liable for its failure to comply with such duties insofar as such failure
results from a failure by the Special Servicer to provide sufficient information
to the Master Servicer to comply with such duties or failure by the Special
Servicer to otherwise comply with its obligations hereunder; provided, further,
that the Special Servicer shall not be liable for its failure to comply with
such duties insofar as such failure results from a failure by the Master
Servicer to provide sufficient information to the extent required herein to the
Special Servicer to comply with such duties or failure by the Master Servicer to
otherwise comply with its obligations hereunder. All references herein to the
respective duties of the Master Servicer and the Special Servicer, and to the
areas in which they may exercise discretion, shall be subject to Section 3.21.

            The parties hereto acknowledge that the 2005-C19 Serviced Mortgage
Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan, the MSCI 2005-HQ6 Serviced
Mortgage Loan and their related Companion Loans are being serviced and
administered under the 2005-C19 Pooling and Servicing Agreement, the LB-UBS
2005-C3 Pooling and Servicing Agreement and the MSCI 2005-HQ6 Pooling and
Servicing Agreement, respectively. The Master Servicer, the Special Servicer,
the Trustee and the Paying Agent shall have no obligation or authority (i) to
service and administer the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3
Serviced Mortgage Loan, the MSCI 2005-HQ6 Serviced Mortgage Loan or their
related Companion Loans (except for the limited duties with respect to the
2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan and
the MSCI 2005-HQ6 Serviced Mortgage Loan expressly provided herein), (ii) to
supervise the 2005-C19 Master Servicer, the 2005-C19 Special Servicer, the
2005-C19 Trustee, the LB-UBS 2005-C3 Master Servicer, the LB-UBS 2005-C3 Special
Servicer, the LB-UBS 2005-C3 Trustee, the MSCI 2005-HQ6 Master Servicer, the
MSCI 2005-HQ6 Special Servicer or the MSCI 2005-HQ6 Trustee or (iii) to make
Servicing Advances or P&I Advances (except to the limited extent described in
Section 4.03 with respect to P&I Advances to be made by the Master Servicer or
the Trustee on the 2005-C19 Serviced Mortgage Loan). In addition to any other
obligations expressly set forth herein by specific reference to any or all of
the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan
or the MSCI 2005-HQ6 Serviced Mortgage Loan, the Master Servicer, the Special
Servicer, the Trustee and the Paying Agent shall have the following obligations
with respect to the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced
Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage Loan, as the case may be:

      Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI
      2005-HQ6 Serviced Mortgage Loan;

            (vii) Each of the Master Servicer, the Special Servicer, the Trustee
      and the Paying Agent shall have the obligations applicable to such party
      under Section 3.18 with respect to the 2005-C19 Serviced Mortgage Loan,
      the LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced

            (viii) The Master Servicer shall have the obligations described

      the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage
      Loan and the MSCI 2005-HQ6 Serviced Mortgage Loan.

            The obligation of the Master Servicer to provide information and
collections to the Paying Agent and the Certificateholders with respect to the
2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan and
the MSCI 2005-HQ6 Serviced Mortgage Loan shall be dependent on its receipt of
the corresponding information and collections from the 2005-C19 Master Servicer,
the 2005-C19 Special Servicer, the LB-UBS 2005-C3 Master Servicer, the LB-UBS
2005-C3 Special Servicer, the MSCI 2005-HQ6 Master Servicer or the MSCI 2005-HQ6
Special Servicer, as the case may be.

            With respect to the Serviced Pari Passu Mortgage Loans, in the event
such Serviced Pari Passu Mortgage Loan or any successor REO Loan is no longer
part of the Mortgage Pool, then (upon request) the Master Servicer and the
Special Servicer will continue to service and administer the related Loan Pair
or any related REO Property, as and to the extent contemplated by the related
Intercreditor Agreement.

            (b) Subject to Section 3.01(a) and Section 6.11, the Master Servicer
and the Special Servicer each shall have full power and authority, acting alone,
to do or cause to be done any and all things in connection with such servicing
and administration which it may deem necessary or desirable. Without limiting
the generality of the foregoing, each of the Master Servicer and the Special
Servicer, in its own name, with respect to each of the Mortgage Loans and
Companion Loans it is obligated to service hereunder, is hereby authorized and
empowered by the Trustee and, pursuant to each Intercreditor Agreement, the
Companion Holders to execute and deliver, on behalf of the Certificateholders,
the Companion Holders and the Trustee or any of them, (i) any and all financing
statements, continuation statements and other documents or instruments necessary
to maintain the lien created by any Mortgage or other security document in the
related Mortgage File on the related Mortgaged Property and related collateral;
(ii) in accordance with the Servicing Standard and subject to Section 3.20 and
Section 6.11, any and all modifications, waivers, amendments or consents to or

and all instruments of satisfaction or cancellation, or of partial or full

the Trustee shall, at the written request of the Master Servicer or the Special
Servicer, promptly execute any limited powers of attorney and other documents
furnished by the Master Servicer or the Special Servicer that are necessary or
appropriate to enable them to carry out their servicing and administrative
duties hereunder; provided, however, that the Trustee shall not be held liable
for any misuse of any such power of attorney by the Master Servicer or the
Special Servicer; provided, further, that, the Master Servicer and the Special
Servicer shall not, without the Trustee's written consent, (A) initiate any
action in the Trustee's name without indicating the Master Servicer's or Special
Servicer's representative capacity or (B) cause the Trustee to be registered to
do business in any state.

            (c) The relationship of each of the Master Servicer and the Special
Servicer to the Trustee under this Agreement is intended by the parties to be
that of an independent contractor and not that of a joint venture, partner or
agent. Unless the same Person acts as both Master Servicer and Special Servicer,
the Master Servicer shall not be responsible for the actions of or failure to
act by the Special Servicer and the Special Servicer shall not be responsible
for the actions of or the failure to act by the Master Servicer.

            (d) Notwithstanding anything herein to the contrary, in no event
shall the Master Servicer make a Servicing Advance with respect to any Companion
Loan to the extent the related Co-Lender Loan has been paid in full or is no
longer included in the Trust Fund.

            (e) Servicing and administration of each Companion Loan (other than
the Non-Serviced Companion Loans) shall continue hereunder for so long as the
corresponding Co-Lender Loan (other than with respect to the Non-Serviced
Mortgage Loans) or any related REO Property is part of the Trust Fund or for
such longer period as any amounts payable by the related Companion Holder to or
for the benefit of the Trust Fund or any party hereto in accordance with the
related Intercreditor Agreement remain due and owing; provided, however, if any
Companion Loan (other than a Non-Serviced Companion Loan) is securitized, the
Master Servicer's servicing obligations and duties with respect to the related
Companion Loan shall be limited to those obligations and duties described in the
related Intercreditor Agreement and this Agreement.

            Section 3.02 Collection of Mortgage Loan Payments.

            (a) Each of the Master Servicer or the Special Servicer shall
undertake reasonable efforts consistent with the Servicing Standard to collect
all payments required under the terms and provisions of the Mortgage Loans and
Companion Loans it is obligated to service hereunder and shall, to the extent
such procedures shall be consistent with this Agreement, follow such collection
procedures in accordance with the Servicing Standard; provided, however, that
nothing herein shall be construed as an express or implied guarantee by the
Master Servicer or the Special Servicer of collectability; provided, further
that with respect to the Mortgage Loans that have Anticipated Repayment Dates,
so long as the related Mortgagor is in compliance with each provision of the
related Mortgage Loan documents, the Master Servicer and Special Servicer
(including the Special Servicer in its capacity as a Certificateholder), shall
not take any enforcement action with respect to the failure of the related
Mortgagor to make any payment of Additional Interest or principal in excess of
the principal component of the constant Periodic Payment, other than requests
for collection, until the maturity date of the related Mortgage Loan; provided
that the Master Servicer or Special Servicer, as the case may be, may take
action to enforce the Trust Fund's right to apply excess cash flow to principal
in accordance with the terms of the Mortgage Loan documents. Consistent with the
foregoing and subject to Section 3.20, the Special Servicer, with regard to a
Specially Serviced Mortgage Loan, or the Master Servicer, with regard to a
Mortgage Loan or Companion Loan (other than the Non-Serviced Mortgage Loans or
the Non-Serviced Companion Loans) that is not a Specially Serviced Mortgage
Loan, may waive any Penalty Interest or late payment charge in connection with
any payment on a Mortgage Loan or Companion Loan (other than the Non-Serviced
Mortgage Loans or the Non-Serviced Companion Loans).

            (b) All amounts collected in respect of any Mortgage Loan or
Companion Loan (other than the Non-Serviced Companion Loans) in the form of
payments from Mortgagors, Liquidation Proceeds (insofar as such Liquidation
Proceeds are of the nature described in clauses (i) through (iii) of the
definition thereof) or Insurance Proceeds shall be applied to either amounts due
and owing under the related Mortgage Note and Mortgage (including, without
limitation, for principal and accrued and unpaid interest) in accordance with
the express provisions of the related Mortgage Note and Mortgage (and, with
respect to a Loan Pair, the related Intercreditor Agreement) or, if required
pursuant to the express provisions of the related Mortgage, or as determined by
the Master Servicer or Special Servicer in accordance with the Servicing
Standard, to the repair or restoration of the related Mortgaged Property, and,
in the absence of such express provisions, shall be applied for purposes of this
Agreement: first, as a recovery of any related and unreimbursed Advances plus
unreimbursed interest accrued thereon; second, as a recovery of Nonrecoverable
Advances, Unliquidated Advances and Workout Delayed Reimbursement Amounts
(including interest on such Nonrecoverable Advances), that were paid from
collections on the Mortgage Loans (allocable to principal) and resulted in
principal from the Mortgage Pool distributed to the Certificateholders being
reduced pursuant to Section 3.05(a) hereof; third, as a recovery of accrued and
unpaid interest at the related Mortgage Rate on such Mortgage Loan, to the
extent such amounts have not been previously advanced, and exclusive of any
portion thereof that constitutes Additional Interest; fourth, as a recovery of
principal of such Mortgage Loan then due and owing, to the extent such amounts
have not been previously advanced, including, without limitation, by reason of
acceleration of the Mortgage Loan following a default thereunder; fifth, in
accordance with the normal servicing practices of the Master Servicer or the
Special Servicer, as a recovery of any other amounts then due and owing under
such Mortgage Loan (other than Additional Interest), including, without
limitation, Prepayment Premiums, Yield Maintenance Charges and Penalty Interest;
sixth, as a recovery of any remaining principal of such Mortgage Loan to the
extent of its entire remaining unpaid principal balance; and seventh, with
respect to any ARD Loan after its Anticipated Repayment Date, as a recovery of
any unpaid Additional Interest. All amounts collected on any Mortgage Loan in
the form of Liquidation Proceeds of the nature described in clauses (iv) through
(vi) of the definition thereof shall be deemed to be applied: first, as a
recovery of any related and unreimbursed Advances plus interest accrued thereon;
second, as a recovery of accrued and unpaid interest at the related Mortgage
Rate on such Mortgage Loan to but not including the Due Date in the Collection
Period of receipt, to the extent such amounts have not been previously advanced,
and exclusive of any portion thereof that constitutes Additional Interest;
third, as a recovery of principal, to the extent such amounts have not been
previously advanced, of such Mortgage Loan to the extent of its entire unpaid
principal balance; and fourth, with respect to any ARD Loan after its
Anticipated Repayment Date, as a recovery of any unpaid Additional Interest. No
such amounts shall be applied to the items constituting additional servicing
compensation as described in the first sentence of either Section 3.11(b) or
3.11(d) unless and until all principal and interest then due and payable on such
Mortgage Loan has been collected. Amounts collected on any REO Loan shall be
deemed to be applied in accordance with the definition thereof. The provisions
of this paragraph with respect to the application of amounts collected on any
Mortgage Loan shall not alter in any way the right of the Master Servicer, the
Special Servicer or any other Person to receive payments from the Certificate
Account as set forth in clauses (ii) through (xv) of Section 3.05(a) from
amounts so applied.

            (c) Within 60 days after the later of (i) the Closing Date and (ii)
the Master Servicer's receipt of the applicable letter of credit, the Master
Servicer shall notify each provider of a letter of credit for each Mortgage Loan
identified as having a letter of credit on the Mortgage Loan Schedule, that the
Master Servicer or the Special Servicer on behalf of the Trustee for the benefit
of the Certificateholders shall be the beneficiary under each such letter of
credit. If a draw upon a letter of credit is needed before its transfer to the
Trust Fund can be completed, the applicable Mortgage Loan Seller shall draw upon
such letter of credit for the benefit of the Trust pursuant to written
instructions from the Master Servicer.

            (d) In the event that the Master Servicer or Special Servicer
receives Additional Interest in any Collection Period, or receives notice from
the related Mortgagor that the Master Servicer or Special Servicer will be
receiving Additional Interest in any Collection Period, the Master Servicer or
Special Servicer, as applicable, will promptly notify the Trustee. Subject to
the provisions of Section 3.02(a) hereof, none of the Master Servicer, the
Trustee or the Special Servicer shall be responsible for any such Additional
Interest not collected after notice from the related Mortgagor.

            (e) With respect to any Mortgage Loan in connection with which the
Mortgagor was required to escrow funds or to post a letter of credit related to
obtaining certain performance objectives described in the applicable Mortgage
Loan documents, the Master Servicer shall, to the extent consistent with the
Servicing Standard, hold such escrows, letters of credit and proceeds thereof as
additional collateral and not apply such items to reduce the principal balance
of such Mortgage Loan unless otherwise required to do so pursuant to the
applicable Mortgage Loan documents.

            Section 3.03 Collection of Taxes, Assessments and Similar Items;
Servicing Accounts; Reserve Accounts.

            (a) The Master Servicer shall, as to all Mortgage Loans (other than
the Non-Serviced Mortgage Loans) and Companion Loans (other than the
Non-Serviced Companion Loans), establish and maintain one or more accounts (the
"Servicing Accounts"), into which all Escrow Payments shall be deposited and
retained, and shall administer such accounts in accordance with the terms of the
Mortgage Loan documents. Each Servicing Account shall be an Eligible Account.
Withdrawals of amounts so collected from a Servicing Account may be made (to the
extent amounts have been escrowed for such purpose) only to: (i) effect payment
of items for which Escrow Payments were collected and comparable items; (ii)
reimburse the Master Servicer, the Trustee or the Fiscal Agent for any
unreimbursed Servicing Advances; (iii) refund to Mortgagors any sums as may be
determined to be overages; (iv) pay interest, if required and as described
below, to Mortgagors on balances in the Servicing Account; (v) pay itself
interest and investment income on balances in the Servicing Account as described
in Section 3.06(b), if and to the extent not required by law or the terms of the
applicable Mortgage Loan to be paid to the Mortgagor; (vi) withdraw amounts
deposited in error or (vii) clear and terminate the Servicing Account at the
termination of this Agreement in accordance with Section 9.01. To the extent
permitted by law or the applicable Mortgage Loan, funds in the Servicing
Accounts may be invested only in Permitted Investments in accordance with the
provisions of Section 3.06 and in accordance with the terms of the related
Mortgage Loan documents. The Master Servicer shall pay or cause to be paid to
the Mortgagors interest, if any, earned on the investment of funds in Servicing
Accounts maintained thereby, if required by law or the terms of the related
Mortgage Loan. If the Master Servicer shall deposit in a Servicing Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from such Servicing Account, any provision herein to the contrary
notwithstanding. The Servicing Accounts shall not be considered part of the
segregated pool of assets constituting REMIC I, REMIC II or the Grantor Trusts.

            (b) The Master Servicer (for the Mortgage Loans other than Specially
Serviced Mortgage Loans, the Non-Serviced Mortgage Loans and REO Loans) or the
Special Servicer (for Specially Serviced Mortgage Loans and REO Loans) shall (i)
maintain accurate records with respect to the related Mortgaged Property
reflecting the status of real estate taxes, assessments and other similar items
that are or may become a lien thereon and the status of insurance premiums and
any ground rents payable in respect thereof and (ii) use reasonable efforts to
obtain, from time to time, all bills for the payment of such items (including
renewal premiums) and shall effect payment thereof prior to the applicable
penalty or termination date and, in any event, prior to the institution of
foreclosure or similar proceedings with respect to the related Mortgaged
Property for nonpayment of such items. For purposes of effecting any such
payment for which it is responsible, the Master Servicer shall apply Escrow
Payments (at the direction of the Special Servicer for Specially Serviced
Mortgage Loans and REO Loans) as allowed under the terms of the related Mortgage
Loan or Companion Loan or, if such Mortgage Loan or Companion Loan does not
require the related Mortgagor to escrow for the payment of real estate taxes,
assessments, insurance premiums, ground rents (if applicable) and similar items,
the Master Servicer shall, as to all Mortgage Loans or Companion Loans, use
reasonable efforts consistent with the Servicing Standard to enforce the
requirement of the related Mortgage that the Mortgagor make payments in respect
of such items at the time they first become due, and, in any event, prior to the
institution of foreclosure or similar proceedings with respect to the related
Mortgaged Property for nonpayment of such items.

            (c) The Master Servicer shall, as to all Mortgage Loans and
Companion Loans (other than the Non-Serviced Mortgage Loans and their related
Companion Loans), subject to Section 3.01(d), make a Servicing Advance with
respect to the related Mortgaged Property in an amount equal to all such funds
as are necessary for the purpose of effecting the payment of (i) real estate
taxes, assessments, penalties and other similar items, (ii) ground rents (if
applicable), and (iii) premiums on Insurance Policies in each instance if and to
the extent Escrow Payments (if any) collected from the related Mortgagor are
insufficient to pay such item when due and the related Mortgagor has failed to
pay such item on a timely basis; provided that the Master Servicer shall not
make any Servicing Advance prior to the penalty date or cancellation date, as
applicable, if the Master Servicer reasonably anticipates in accordance with the
Servicing Standard that the Mortgagor will pay such amount on or before the
penalty date or cancellation date; provided, further, that the Master Servicer
shall not be obligated to make any Servicing Advance that would, if made,
constitute a Nonrecoverable Servicing Advance but may, but is not required to,
pay such amounts out of funds in the Certificate Account if it determines that
such payment would be in the best interests of the Certificateholders and such
payment may be withdrawn from amounts in the Certificate Account; provided that
the Master Servicer may conclusively rely upon any such determination by the
Special Servicer. All such Servicing Advances or amounts withdrawn from the
Certificate Account shall be reimbursable in the first instance from related
collections from the Mortgagors, and further as provided in Section 3.05(a). No
costs incurred by the Master Servicer, the Trustee or the Fiscal Agent in
effecting the payment of real estate taxes, assessments and, if applicable,
ground rents on or in respect of such Mortgaged Properties shall, for purposes
of this Agreement, including, without limitation, the Paying Agent's calculation
of monthly distributions to Certificateholders, be added to the unpaid Stated
Principal Balances of the related Mortgage Loans or Companion Loans,
notwithstanding that the terms of such Mortgage Loans or Companion Loans so
permit. The foregoing shall in no way limit the Master Servicer's ability to
charge and collect from the Mortgagor such costs together with interest thereon.
In addition to any other rights to recovery set forth herein with respect to any
Servicing Advance made on the 1000 & 1100 Wilson Whole Loan, the NGP Rubicon GSA
Whole Loan and the Westfield San Francisco Centre Whole Loan, as applicable, the
Master Servicer, the Trustee and/or the Fiscal Agent, as applicable, shall be
entitled to recovery of a portion of such amounts without duplication from the
holder of the related Pari Passu Companion Loans pursuant to the terms of the
related Intercreditor Agreement and the related pooling and servicing agreement
(or similar agreement).

            The Special Servicer shall give the Master Servicer, the Trustee and
the Fiscal Agent not less than five Business Days' notice with respect to
Servicing Advances to be made on any Specially Serviced Mortgage Loan or REO
Property, before the date on which the Master Servicer is required to make any
Servicing Advance with respect to a given Mortgage Loan, Companion Loan or REO
Property; provided, however, that only two Business Days' notice shall be
required in respect of Servicing Advances required to be made on an urgent or
emergency basis (which may include, without limitation, Servicing Advances
required to make tax or insurance payments). In addition, the Special Servicer
shall provide the Master Servicer, the Trustee and the Fiscal Agent with such
information in its possession as the Master Servicer, the Trustee or the Fiscal
Agent, as applicable, may reasonably request to enable the Master Servicer, the
Trustee or the Fiscal Agent, as applicable, to determine whether a requested
Servicing Advance would constitute a Nonrecoverable Servicing Advance. Any
request by the Special Servicer that the Master Servicer make a Servicing
Advance shall be deemed to be a determination by the Special Servicer that such
requested Servicing Advance is not a Nonrecoverable Servicing Advance, and the
Master Servicer shall be entitled to conclusively rely on such determination. On
the fourth Business Day before each Distribution Date, the Special Servicer
shall report to the Master Servicer the Special Servicer's determination as to
whether any Servicing Advance previously made with respect to a Specially
Serviced Mortgage Loan or REO Loan is a Nonrecoverable Servicing Advance. The
Master Servicer shall be entitled to conclusively rely on such a determination.

            If the Master Servicer is required under any provision of this
Agreement (including, but not limited to, this Section 3.03(c)) to make a
Servicing Advance, but does not do so within 15 days after such Advance is
required to be made (or such shorter period as may be required to avoid
foreclosure of liens for delinquent real estate taxes or a lapse in insurance
coverage), the Trustee shall, if a Responsible Officer of the Trustee has actual
knowledge of such failure on the part of the Master Servicer, give written
notice of such failure to the Master Servicer. If such Servicing Advance is not
made by the Master Servicer within three Business Days after such notice then
(subject to a determination that such Servicing Advance would not be a
Nonrecoverable Servicing Advance) the Trustee or Fiscal Agent shall make such
Servicing Advance. Any failure by the Master Servicer to make a Servicing
Advance hereunder shall constitute an Event of Default by the Master Servicer
subject to and as provided in Section 7.01.

            (d) In connection with its recovery of any Servicing Advance from
the Certificate Account pursuant to Section 3.05(a), each of the Master
Servicer, the Trustee and the Fiscal Agent shall be entitled to receive, out of
any amounts then on deposit in the Certificate Account, any unpaid interest at
the Reimbursement Rate in effect from time to time, compounded annually, accrued
on the amount of such Servicing Advance (to the extent made with its own funds)
from the date made to but not including the date of reimbursement such interest
to be payable, subject to the terms of the related Intercreditor Agreement with
respect to a Loan Pair, first out of late payment charges and Penalty Interest
received on the related Mortgage Loan or REO Property during the Collection
Period in which such reimbursement is made, and to the extent that such late
payment charges and Penalty Interest are insufficient, but only after or at the
same time the related Advance has been or is reimbursed pursuant to this
Agreement, then from general collections on the Mortgage Loans then on deposit
in the Certificate Account. The Master Servicer shall reimburse itself, the
Trustee or the Fiscal Agent, as applicable, for any outstanding Servicing
Advance made thereby as soon as practicable after funds available for such
purpose have been received by the Master Servicer, and in no event shall
interest accrue in accordance with this Section 3.03(d) on any Servicing Advance
as to which the corresponding Escrow Payment or other similar payment by the
Mortgagor was received by the Master Servicer on or prior to the date the
related Servicing Advance was made. Notwithstanding anything herein to the
contrary, in no event shall the Master Servicer, the Trustee or the Fiscal Agent
make any Servicing Advances with respect to any Companion Loan after the related
Co-Lender Loan has been paid in full.

            (e) The determination by the Master Servicer or the Special Servicer
that the Master Servicer has made a Nonrecoverable Servicing Advance or that any
proposed Servicing Advance, if made, would constitute a Nonrecoverable Servicing
Advance, shall be made in accordance with the Servicing Standard and shall be
evidenced by an Officer's Certificate delivered promptly to the Trustee, the
Fiscal Agent and the Depositor, setting forth the basis for such determination,
together with a copy of any Appraisal (the cost of which may be paid out of the
Certificate Account pursuant to Section 3.05(a)) of the related Mortgaged
Property or REO Property, as the case may be; which Appraisal shall be conducted
pursuant to Section 3.09(a) by the Master Servicer, or by or on behalf of the
Special Servicer if the Mortgage Loan is a Specially Serviced Mortgage Loan or,
if no such Appraisal has been performed, a copy of an Appraisal of the related
Mortgaged Property or REO Property, performed within the twelve months preceding
such determination and the party delivering such appraisal has no actual
knowledge of a material adverse change in the condition of the related Mortgaged
Property that would draw into question the applicability of such Appraisal, by
an Independent Appraiser or other expert in real estate matters, and further
accompanied by related Mortgagor operating statements and financial statements,
budgets and rent rolls of the related Mortgaged Property and any engineers'
reports, environmental surveys or similar reports that the Master Servicer or
the Special Servicer may have obtained and that support such determination. The
Master Servicer shall be entitled to rely, conclusively, on any determination by
the Special Servicer that a Servicing Advance, if made, would be a
Nonrecoverable Advance. The Trustee and the Fiscal Agent shall be entitled to
rely, conclusively, on any determination by the Master Servicer or the Special
Servicer that a Servicing Advance, if made, would be a Nonrecoverable Advance;
provided, however, that, if the Master Servicer has failed to make a Servicing
Advance for reasons other than a determination by the Master Servicer or the
Special Servicer that such Servicing Advance would be a Nonrecoverable Advance,
the Trustee shall make such Servicing Advance within the time periods required
by Section 3.03(c) unless the Trustee in good faith, makes a determination that
such Servicing Advance would be a Nonrecoverable Advance; provided, further,
however, that if the Trustee fails to make such Servicing Advance for reasons
other than a determination by the Trustee that such Servicing Advance would be a
Nonrecoverable Advance, the Fiscal Agent shall make such Servicing Advance
within the time periods required by Section 3.03(c) unless the Fiscal Agent in
good faith, makes a determination that such Servicing Advance would be a
Nonrecoverable Advance.

            (f) The Master Servicer shall, as to all Mortgage Loans (other than
the Non-Serviced Mortgage Loans) and Companion Loans (other than the
Non-Serviced Companion Loans), establish and maintain, as applicable, one or
more accounts (the "Reserve Accounts"), into which all Reserve Funds, if any,
shall be deposited and retained. Withdrawals of amounts so deposited may be made
(i) to pay for, or to reimburse the related Mortgagor in connection with, the
related environmental remediation, repairs and/or capital improvements at the
related Mortgaged Property if the repairs and/or capital improvements have been
completed, and such withdrawals are made in accordance with the Servicing
Standard and the terms of the related Mortgage Note, Mortgage and any agreement
with the related Mortgagor governing such Reserve Funds and any other items for
which such Reserve Funds were intended pursuant to the loan documents and (ii)
to pay the Master Servicer interest and investment income earned on amounts in
the Reserve Accounts as described below if permitted under the related Mortgage
Loan documents. To the extent permitted in the applicable Mortgage, funds in the
Reserve Accounts to the extent invested may be only invested in Permitted
Investments in accordance with the provisions of Section 3.06. All Reserve
Accounts shall be Eligible Accounts. The Reserve Accounts shall not be
considered part of the segregated pool of assets comprising REMIC I, REMIC II or
the Grantor Trust. Consistent with the Servicing Standard, the Master Servicer
may waive or extend the date set forth in any agreement governing such Reserve
Funds by which the required repairs and/or capital improvements at the related
Mortgaged Property must be completed.

            Section 3.04 Certificate Account, Interest Reserve Account,
Gain-on-Sale Reserve Account, Additional Interest Account, Distribution Account,
Companion Distribution Account, Class A-3SF Floating Rate Account and Class
A-MFL Floating Rate Account.

            (a) The Master Servicer shall establish and maintain one or more
accounts (collectively, the "Certificate Account"), held on behalf of the
Trustee in trust for the benefit of the Certificateholders and, to the extent
funds on deposit in the Certificate Account are allocable to the related
Companion Loans (other than the Non-Serviced Companion Loans), the related
Companion Holders, but solely to the extent set forth in the related
Intercreditor Agreement and subject to any provisions relating to subordination
of rights with respect to the Co-Lender Loans. The Certificate Account shall be
an Eligible Account. The Master Servicer shall deposit or cause to be deposited
in the Certificate Account, within one Business Day of receipt of available
funds (in the case of payments by Mortgagors or other collections on the
Mortgage Loans or the Companion Loans) or as otherwise required hereunder, the
following payments and collections received or made by the Master Servicer or on
its behalf subsequent to the Cut-Off Date (other than in respect of principal
and interest on the Mortgage Loans or the Companion Loans (other than the
Non-Serviced Companion Loans) due and payable on or before the Cut-Off Date,
which payments shall be delivered promptly to the applicable Mortgage Loan
Seller or its designee, with negotiable instruments endorsed as necessary and
appropriate without recourse), other than amounts received from Mortgagors which
are to be used to purchase defeasance collateral, or payments (other than
Principal Prepayments) received by it on or prior to the Cut-Off Date but
allocable to a period subsequent thereto:

            (i) all payments on account of principal of the Mortgage Loans or
      Companion Loans (other than the Non-Serviced Companion Loans), including
      Principal Prepayments;

            (ii) all payments on account of interest on the Mortgage Loans or
      Companion Loans (other than the Non-Serviced Companion Loans), including
      Additional Interest;

            (iii) all Prepayment Premiums and Yield Maintenance Charges (other
      than with respect to the Non-Serviced Companion Loans);

            (iv) all Insurance Proceeds and Liquidation Proceeds (other than
      Liquidation Proceeds described in clause (vi) of the definition thereof
      that are required to be deposited in the Distribution Account pursuant to
      Section 9.01) received in respect of any Mortgage Loan or Companion Loan
      (other than the Non-Serviced Companion Loans) (including, without
      limitation, any amounts representing recoveries of Nonrecoverable Advances
      or Unliquidated Advances, including interest on such Nonrecoverable
      Advances or Unliquidated Advances in respect of the related Mortgage
      Loans);

            (v) any amounts required to be deposited by the Master Servicer
      pursuant to Section 3.06(b) in connection with losses incurred with
      respect to Permitted Investments of funds held in the Certificate Account;

            (vi) any amounts required to be deposited by the Master Servicer or
      the Special Servicer pursuant to Section 3.07(b) in connection with losses
      resulting from a deductible clause in a blanket hazard policy;

            (vii) any amounts required to be transferred from an REO Account
      pursuant to Section 3.16(c) and any amounts received from a Mortgage Loan
      Seller with respect to a Special Reserve Account pursuant to Section
      2.02(d);

            (viii) any amount in respect of Purchase Prices and Substitution
      Shortfall Amounts pursuant to Section 2.03(b);

            (ix) any amount required to be deposited by the Master Servicer
      pursuant to Section 3.19(a) in connection with Prepayment Interest
      Shortfalls;

            (x) any amount required to be deposited by the Master Servicer
      pursuant to Section 3.03(d) and 4.03(d) in connection with reimbursing the
      Trust Fund for interest paid on a P&I Advance or Servicing Advance, as
      applicable;

            (xi) any amount paid by a Mortgagor to cover items for which a
      Servicing Advance has been previously made and for which the Master
      Servicer, the Special Servicer, the Trustee or the Fiscal Agent, as
      applicable, has been previously reimbursed out of the Certificate Account;

            (xii) any amount required to be deposited by the Master Servicer or
      the Special Servicer pursuant to Section 3.11(b) and 3.11(d),
      respectively, in connection with reimbursing the Trust Fund for Additional
      Trust Fund Expenses; and

            (xiii) all amounts remitted or advanced by the 2005-C19 Master
      Servicer, the LB-UBS 2005-C3 Master Servicer or the MSCI 2005-HQ6 Master
      Servicer in respect of the 2005-C19 Serviced Mortgage Loan, the LB-UBS
      2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage
      Loan, as the case may be, pursuant to the 2005-C19 Pooling and Servicing
      Agreement, the LB-UBS 2005-C3 Pooling and Servicing Agreement, the MSCI
      2005-HQ6 Pooling and Servicing Agreement and the related Intercreditor
      Agreements.

            The foregoing requirements for deposit in the Certificate Account
shall be exclusive. Notwithstanding the foregoing, actual payments from
Mortgagors in the nature of Escrow Payments, amounts to be deposited in Reserve
Accounts, and amounts that the Master Servicer and the Special Servicer are
entitled to retain as additional servicing compensation pursuant to Sections
3.11(b) and 3.11(d), need not be deposited by the Master Servicer in the
Certificate Account. If the Master Servicer shall deposit in the Certificate
Account any amount not required to be deposited therein, it may at any time
withdraw such amount from the Certificate Account, any provision herein to the
contrary notwithstanding. The Master Servicer shall promptly deliver to the
Special Servicer as additional servicing compensation in accordance with Section
3.11(d), assumption fees, late payment charges (to the extent not applied to pay
interest on Advances as provided in Sections 3.03(d) or 4.03(d) or Additional
Trust Fund Expenses as provided in Section 3.11(d)) and other transaction fees
or other expenses received by the Master Servicer to which the Special Servicer
is entitled pursuant to either of such Sections upon receipt of a certificate of
a Servicing Officer of the Special Servicer describing the item and amount. The
Certificate Account shall be maintained as a segregated account, separate and
apart from trust funds created for mortgage pass-through certificates of other
series and the other accounts of the Master Servicer.

            The Master Servicer may maintain, as part of the Certificate
Account, a subaccount for each Companion Loan (other than the Non-Serviced
Companion Loans) on behalf of and in trust for the benefit of the related
Companion Holder, into which subaccount the Master Servicer shall deposit or
cause to be deposited all amounts described in the first paragraph of this
Section 3.04(a) to the extent allocable to the related Companion Loan in
accordance with this Agreement and the related Intercreditor Agreement, and out
of which subaccount the Master Servicer may make withdrawals to the extent
withdrawals of such funds are provided for in Section 3.05(a) of this Agreement
or in the related Intercreditor Agreement. Each such subaccount shall be an
Eligible Account or a subaccount of an Eligible Account and shall be entitled
"Wachovia Bank, National Association, as Master Servicer, on behalf of and in
trust for the related Companion Holder."

            Upon receipt of any of the amounts described in clauses (i) through
(iv), (xi), (xii) and (xiii) above with respect to any Mortgage Loan or
Companion Loan, the Special Servicer shall promptly, but in no event later than
one Business Day after receipt of available funds, remit such amounts (net of
any reimbursable expenses incurred by the Special Servicer) to or at the
direction of the Master Servicer for deposit into the Certificate Account in
accordance with the second preceding paragraph, unless the Special Servicer
determines, consistent with the Servicing Standard, that a particular item
should not be deposited because of a restrictive endorsement. Any such amounts
received by the Special Servicer with respect to an REO Property shall be
deposited by the Special Servicer into the REO Account and remitted to the
Master Servicer for deposit into the Certificate Account pursuant to Section
3.16(c). With respect to any such amounts paid by check to the order of the
Special Servicer, the Special Servicer shall endorse such check to the order of
the Master Servicer and shall deliver promptly, but in no event later than three
Business Days after receipt, any such check to the Master Servicer by overnight
courier, unless the Special Servicer determines, consistent with the Servicing
Standard, that a particular item cannot be so endorsed and delivered because of
a restrictive endorsement or other appropriate reason.

            (b) The Trustee shall establish and maintain one or more trust
accounts (collectively, the "Distribution Account") at the office of the Paying
Agent to be held in trust for the benefit of the Certificateholders (other than
the Class Z Certificateholders). The Distribution Account shall be an Eligible
Account. The Trustee hereby authorizes the Paying Agent to make deposits in and
withdrawals from the Distribution Account in accordance with the terms of this
Agreement. The Master Servicer shall deliver to the Paying Agent each month on
or before 1:30 p.m. New York City time on the P&I Advance Date therein, for
deposit in the Distribution Account, an aggregate amount of immediately
available funds equal to that portion of the Available Distribution Amount
(calculated without regard to clauses (a)(ii), (a)(v) and (b)(ii)(B) of the
definition thereof) for the related Distribution Date then on deposit in the
Certificate Account, together with (i) any Prepayment Premiums, Yield
Maintenance Charges and/or Additional Interest received on the Mortgage Loans
during the related Collection Period, and (ii) in the case of the final
Distribution Date, any additional amounts contemplated by the third paragraph of
Section 9.01.

            The Companion Paying Agent shall establish and maintain one or more
trust accounts for distributions to the Companion Loans (other than the
Non-Serviced Companion Loans) (collectively, the "Companion Distribution
Account") to be held on behalf of the related Companion Holder(s). The Companion
Distribution Account shall be an Eligible Account and may be a subaccount of the
Certificate Account. The Master Servicer hereby authorizes the Companion Paying
Agent to make deposits in and withdrawals from the Companion Distribution
Account in accordance with the terms of this Agreement. Unless the Companion
Distribution Account is the related subaccount or subaccounts of the Certificate
Account as allowed by the last sentence of the definition of Companion
Distribution Account, the Master Servicer shall deliver to the Companion Paying
Agent each month on or before 2:00 p.m. New York City time on the P&I Advance
Date therein (or, with respect to the NGP Rubicon GSA Pool Pari Passu Companion
Loan, on the Business Day following the Determination Date, or, with respect to
the Westfield San Francisco Centre Pari Passu Companion Loan, one Business Day
prior to the "master servicer remittance date" with respect to the
securitization holding the Westfield San Francisco Centre Pari Passu Companion
Loan (which date is expected to be the Business Day immediately preceding each
distribution date for such securitization, which distribution date is expected
to be not earlier than four Business Days after the sixth calendar day of each
month)) for deposit in the Companion Distribution Account, an aggregate amount
of immediately available funds equal to the amount available to be distributed
to the related Companion Holder(s) pursuant to the related Intercreditor
Agreement.

            In addition, the Master Servicer shall, as and when required
hereunder, deliver to the Paying Agent for deposit in the Distribution Account:

            (i) any P&I Advances required to be made by the Master Servicer in
      accordance with Section 4.03(a); and

            (ii) the Purchase Price paid in connection with the purchase by the
      Master Servicer of all of the Mortgage Loans and any REO Properties
      pursuant to Section 9.01, exclusive of the portion of such amounts
      required to be deposited in the Certificate Account pursuant to Section
      9.01.

            The Paying Agent shall, upon receipt, deposit in the Distribution
Account any and all amounts received by the Paying Agent that are required by
the terms of this Agreement to be deposited therein.

            (c) The Trustee shall establish and maintain one or more accounts
(collectively, the "Interest Reserve Account"), held in trust for the benefit of
the Certificateholders). The Interest Reserve Account shall be an Eligible
Account. On or before each Distribution Date in February and, during each year
that is not a leap year, January, the Master Servicer shall withdraw from the
Certificate Account and remit to the Trustee for deposit in the Interest Reserve
Account, with respect to each Interest Reserve Loan, an amount equal to the
Interest Reserve Amount in respect of such Interest Reserve Loan, for such
Distribution Date (such withdrawal from the Certificate Account to be made out
of general collections on the Mortgage Pool where any related P&I Advance was
deposited in the Distribution Account).

            (d) Prior to any Collection Period during which Additional Interest
is received, and upon notification from the Master Servicer or Special Servicer
pursuant to Section 3.02(d), the Trustee (on behalf of the Certificateholders)
shall establish and maintain the Additional Interest Account in the name of the
Trustee in trust for the benefit of the Class Z Certificateholders. The
Additional Interest Account shall be established and maintained as an Eligible
Account. Prior to the applicable Distribution Date, the Master Servicer shall
remit to the Trustee for deposit in the Additional Interest Account an amount
equal to the Additional Interest received during the applicable Collection
Period.

            Following the distribution of Additional Interest to the Class Z
Certificateholders, on the first Distribution Date after which there are no
longer any Mortgage Loans outstanding which pursuant to their terms could pay
Additional Interest, the Trustee shall terminate the Additional Interest
Account.

            (e) The Paying Agent, on behalf of the Trustee for the benefit of
the Certificateholders, shall establish (upon notice from Special Servicer of an
event occurring that generates Gain-on-Sale Proceeds) and maintain the
Gain-on-Sale Reserve Account in the name of the Paying Agent on behalf of the
Trustee for the benefit of the Certificateholders. The Gain-on-Sale Reserve
Account shall be maintained as a segregated account, separate and apart from
trust funds for mortgage pass-through certificates of other series administered
by the Paying Agent and other accounts of the Paying Agent. Upon the disposition
of any REO Property in accordance with Section 3.09 or Section 3.18, the Special
Servicer will calculate the Gain-on-Sale Proceeds, if any, realized in
connection with such sale and remit such funds to the Paying Agent for deposit
into the Gain-on-Sale Reserve Account.

            (f) Funds in the Certificate Account, the Interest Reserve Account,
the Distribution Account, the Class A-3SF Floating Rate Account, the Class A-MFL
Floating Rate Account, the Additional Interest Account and the Gain-on-Sale
Reserve Account may be invested only in Permitted Investments in accordance with
the provisions of Section 3.06. Funds on deposit in the Gain-on-Sale Reserve
Account shall be invested pursuant to Section 3.06. The Master Servicer shall
give written notice to the Trustee, the Special Servicer and the Rating Agencies
of the location of the Certificate Account as of the Closing Date and of the new
location of the Certificate Account prior to any change thereof. The Paying
Agent shall give written notice to the Trustee, the Master Servicer, the Special
Servicer and the Rating Agencies of any new location of the Distribution Account
prior to any change thereof.

            (g) On or before the Closing Date, the Paying Agent shall establish
and maintain the Class A-3SF Floating Rate Account and the Class A-MFL Floating
Rate Account in trust for the benefit of the Class A-3SF Certificateholders and
the Class A-MFL Certificateholders, respectively, and the related Swap
Counterparty. The Class A-3SF Floating Rate Account and the Class A-MFL Floating
Rate Account shall (i) at all times be an Eligible Account and (ii) relate
solely to the Class A-3SF Certificates and the Class A-MFL Certificates,
respectively, and amounts payable in respect of the related Swap Contract.

            (h) The Paying Agent shall deposit into the Class A-3SF Floating
Rate Account and the Class A-MFL Floating Rate Account all amounts received in
respect of distributions on the Class A-3SF Regular Interest and the Class A-MFL
Regular Interest, respectively, as specified in Section 3.04(b), and shall
immediately deposit into the Class A-3SF Floating Rate Account and the Class
A-MFL Floating Account all amounts received under the related Swap Contract.

      share, together with amounts available from collections in the certificate
      account created under the 2005-C19 Pooling and Servicing Agreement, the
      LB-UBS 2005-C3 Pooling and Servicing Agreement and the MSCI 2005-HQ6

      applicable, or, in the case of the AmericasMart Loan, other expenses that
      relate to the servicing of the AmericasMart Loan) and interest thereon),
      subject in each case to the terms of the related Intercreditor Agreement;
      provided, however, that any reimbursement of Nonrecoverable Advances or
      Workout Delayed Reimbursement Amounts payable pursuant to this Section
      3.05(a)(vii), with respect to Nonrecoverable Advances, shall be deemed to
      be recovered, first, from collections or receipts on the Mortgage Loans
      and REO Properties in respect of principal and then in respect of interest
      and other collections, and, with respect to Workout Delayed Reimbursement
      Amounts, only out of collections and receipts on the Mortgage Loans and

      respectively), as applicable; provided that the Fiscal Agent's, the
      Trustee's, the Master Servicer's, the Special Servicer's and the 2005-C19
      Master Servicer's rights to payment pursuant to this clause (viii) with
      respect to interest on any Advance shall be satisfied (A) subject to and

            (xxiii) to clear and terminate the Certificate Account at the
      termination of this Agreement pursuant to Section 9.01.

            The Master Servicer shall keep and maintain separate accounting
records, on a loan-by-loan basis when appropriate, in connection with any
withdrawal from the Certificate Account pursuant to clauses (ii)-(xxiii) above.
Upon request, the Master Servicer shall provide to the Trustee such records and
any other information in the possession of the Master Servicer to enable the
Trustee to determine the amounts attributable to REMIC I (with respect to the
Mortgage Loans) and the Companion Loans. The Master Servicer shall, to the
extent permitted by the terms of the related Intercreditor Agreement, make
claims for reimbursement from the related Companion Holder in connection with
related Servicing Advances and interest thereon and other related expenses so as
to minimize the total amount of withdrawals on the Certificate Account for such
items. Nothing in the foregoing sentence shall limit the Master Servicer's
rights to be reimbursed for claims relating to the Companion Loans that are
reimbursable claims pursuant to the terms of this Agreement. Notwithstanding
anything in this Section 3.05(a) to the contrary, in no event shall the Master
Servicer withdraw from funds on deposit in the Certificate Account any amount to
be applied to, or to provide reimbursement for, any amounts referenced in this
Section 3.05(a) (other than amounts referenced in clause (xix)) which relate to
any Companion Loan to the extent the related Co-Lender Loan has been paid in
full in a prior Collection Period. For the avoidance of doubt, in no event shall
the Master Servicer withdraw from funds on deposit in the Certificate Account
any amounts allocable to a Serviced Pari Passu Companion Loan (other than
Penalty Interest and late payment charges) to be applied to, or to provide
reimbursement for, any costs, expenses, indemnities, losses or liabilities
relating or allocable to any Mortgage Loan or Companion Loan other than such
Serviced Pari Passu Companion Loan or the related Serviced Pari Passu Mortgage
Loan.

            The Master Servicer shall pay to the Special Servicer (or to third
party contractors at the direction of the Special Servicer), the Trustee or the
Fiscal Agent from the Certificate Account amounts permitted to be paid to the
Special Servicer (or to such third party contractors), the Trustee or the Fiscal
Agent therefrom promptly upon receipt of a certificate of a Servicing Officer of
the Special Servicer or of a Responsible Officer of the Trustee, describing the
item and amount to which the Special Servicer (or such third party contractors),
the Trustee or the Fiscal Agent is entitled. The Master Servicer may rely
conclusively on any such certificate and shall have no duty to re-calculate the
amounts stated therein. With respect to any reimbursement to be made hereunder
to the 2005-C19 Master Servicer, the 2005-C19 Special Servicer, the LB-UBS
2005-C3 Master Servicer, the LB-UBS 2005-C3 Special Servicer, the MSCI 2005-HQ6
Master Servicer or the MSCI 2005-HQ6 Special Servicer in respect of any Advance
(as defined in the 2005-C19 Pooling and Servicing Agreement, the LB-UBS 2005-C3
Pooling and Servicing Agreement or the MSCI 2005-HQ6 Pooling and Servicing
Agreement, as the case may be) made by such parties subsequently determined to
be a nonrecoverable advance pursuant to the terms of the 2005-C19 Pooling and
Servicing Agreement, the LB-UBS 2005-C3 Pooling and Servicing Agreement or the
MSCI 2005-HQ6 Pooling and Servicing Agreement, as the case may be, the Master
Servicer may conclusively rely on a written statement from such party delivered
to the Master Servicer that such Advance (as defined in the 2005-C19 Pooling and
Servicing Agreement, the LB-UBS 2005-C3 Pooling and Servicing Agreement or the
MSCI 2005-HQ6 Pooling and Servicing Agreement, as the case may be) is a
nonrecoverable advance under the terms of the 2005-C19 Pooling and Servicing
Agreement, the LB-UBS 2005-C3 Pooling and Servicing Agreement or the MSCI
2005-HQ6 Pooling and Servicing Agreement, as the case may be. The Special
Servicer shall keep and maintain separate accounting for each Specially Serviced
Mortgage Loan and REO Property, on a loan-by-loan and property-by-property
basis, for the purpose of justifying any request for withdrawal from the
Certificate Account. With respect to each Mortgage Loan or Companion Loan for
which it makes an Advance, the Trustee shall similarly keep and maintain
separate accounting for each Mortgage Loan or Companion Loan, on a loan-by-loan
and property-by-property basis, for the purpose of justifying any request for
withdrawal from the Certificate Account for reimbursements of Advances or
interest thereon. With respect to each Mortgage Loan or Companion Loan for which
it makes an Advance, the Fiscal Agent shall similarly keep and maintain separate
accounting, on a loan-by-loan and property-by-property basis, for the purpose of
justifying any request for withdrawal from the Certificate Account for
reimbursements of Advances or interest thereon.

            Upon the determination that a previously made Advance is a
Nonrecoverable Advance, instead of obtaining reimbursement out of general
collections immediately, the Master Servicer, the Trustee or the Fiscal Agent,
as applicable, may, in its sole discretion, elect to obtain reimbursement for
such Nonrecoverable Advance over time (not to exceed twelve (12) months or such
longer period of time as agreed to by the Master Servicer, the Trustee or the
Fiscal Agent, as applicable, and the Controlling Class Representative, each in
its sole discretion, and the unreimbursed portion of such Advance will accrue
interest at the Prime Rate. At any time after such a determination to obtain
reimbursement over time, the Master Servicer, the Special Servicer, the Trustee
or the Fiscal Agent, as applicable, may, in its sole discretion and subject to
the immediately following paragraph, decide to obtain reimbursement immediately.
The fact that a decision to recover such Nonrecoverable Advances over time, or
not to do so, benefits some Classes of Certificateholders to the detriment of
other Classes shall not, with respect to the Master Servicer, constitute a
violation of the Servicing Standard and/or with respect to the Trustee,
constitute a violation of any fiduciary duty to Certificateholders or
contractual duty hereunder.

            The Master Servicer or the Trustee, as applicable, shall give
Moody's, Fitch and S&P at least 15 days notice prior to any reimbursement to it
of Nonrecoverable Advances from amounts in the Certificate Account allocable to
interest on the Mortgage Loans unless (1) the Master Servicer or the Trustee, as
applicable, determines in its sole discretion that waiting 15 days after such a
notice could jeopardize the Master Servicer's or the Trustee's ability, as
applicable, to recover such Nonrecoverable Advances, (2) changed circumstances
or new or different information becomes known to the Master Servicer or the
Trustee, as applicable, that could affect or cause a determination of whether
any Advance is a Nonrecoverable Advance, whether to defer reimbursement of a
Nonrecoverable Advance or the determination in clause (1) above, or (3) the
Master Servicer has not timely received from the Trustee information requested
by the Master Servicer to consider in determining whether to defer reimbursement
of a Nonrecoverable Advance; provided that, if clause (1), (2) or (3) apply, the
Master Servicer or the Trustee, as applicable, shall give Moody's, Fitch and S&P
notice of an anticipated reimbursement to it of Nonrecoverable Advances from
amounts in the Certificate Account or Distribution Account, as applicable,
allocable to interest on the Mortgage Loans as soon as reasonably practicable in
such circumstances. The Master Servicer and the Trustee, as applicable, shall
have no liability for any loss, liability or expense resulting from any notice
provided to Moody's, Fitch and S&P contemplated by the immediately preceding
sentence.

            If the Master Servicer, the Trustee or the Fiscal Agent, as
applicable, is reimbursed out of general collections for any unreimbursed
Advances that are determined to be Nonrecoverable Advances (together with any
interest accrued and payable thereon), then (for purposes of calculating
distributions on the Certificates) such reimbursement and payment of interest
shall be deemed to have been made: first, out of the Principal Distribution
Amount, which, but for its application to reimburse a Nonrecoverable Advance
and/or to pay interest thereon, would be included in the Available Distribution
Amount, for any subsequent Distribution Date, and second, out of other amounts
which, but for their application to reimburse a Nonrecoverable Advance and/or to
pay interest thereon, would be included in the Available Distribution Amount for
any subsequent Distribution Date. If and to the extent that any payment is
deemed to be applied in accordance with clause first above to reimburse a
Nonrecoverable Advance or to pay interest thereon, then the Principal
Distribution Amount for such Distribution Date shall be reduced, to not less
than zero, by the amount of such reimbursement. If and to the extent (i) any
Advance is determined to be a Nonrecoverable Advance, (ii) such Advance and/or
interest thereon is reimbursed out of the Principal Distribution Amount as
contemplated by clause first above and (iii) the particular item for which such
Advance was originally made is subsequently collected out of payments or other
collections in respect of the related Mortgage Loan, then the Principal
Distribution Amount for the Distribution Date that corresponds to the Collection
Period in which such item was recovered shall be increased by an amount equal to
the lesser of (A) the amount of such item and (B) any previous reduction in the
Principal Distribution Amount for a prior Distribution Date pursuant to clause
first above resulting from the reimbursement of the subject Advance and/or the
payment of interest thereon.

            (b) The Paying Agent may, from time to time, make withdrawals from
the Distribution Account for any of the following purposes (in no particular
order of priority):

            (i) to make deemed distributions to itself as holder of the REMIC I
      Regular Interests, to make distributions to the Class A-3SF Floating Rate
      Account and the Class A-MFL Floating Rate Account with respect to the
      Class A-3SF Regular Interest and the Class A-MFL Regular Interest,
      respectively, pursuant to this Agreement, and to make distributions to
      Certificateholders on each Distribution Date, pursuant to Sections 4.01
      and 9.01, as applicable;

            (ii) to pay the Trustee and the Fiscal Agent or any of their
      respective directors, officers, employees and agents, as the case may be,
      any amounts payable or reimbursable to any such Person pursuant to Section
      8.05 and Section 8.19, as applicable;

            (iii) to pay the Trustee the Trustee Fee as contemplated by Section
      8.05(a) hereof with respect to each Mortgage Loan and REO Loan and to pay
      the Trustee, as additional compensation, interest and investment income,
      if any, earned in respect of amounts held in the Distribution Account as
      provided in Section 3.06, but only to the extent of the Net Investment
      Earnings with respect to such account for the related Distribution Date;

            (iv) to pay for the cost of the Opinions of Counsel sought by the
      Trustee (A) as provided in clause (v) of the definition of "Disqualified
      Organization", (B) as contemplated by Section 3.20(d), 9.02(a) and
      10.01(h), or (C) as contemplated by Section 11.01(a) or 11.01(c) in
      connection with any amendment to this Agreement requested by the Trustee
      which amendment is in furtherance of the rights and interests of
      Certificateholders; provided that a portion of such costs shall be
      allocated pursuant to the 2005-C19 Pooling and Servicing Agreement, the
      LB-UBS 2005-C3 Pooling and Servicing Agreement, the MSCI 2005-HQ6 Pooling
      and Servicing Agreement and the related Intercreditor Agreement if such
      costs relate to the AmericasMart Whole Loan, the 101 Avenue of the
      Americas Whole Loan or the U-Haul Portfolio Whole Loan;

            (v) to pay any and all federal, state and local taxes imposed on
      REMIC I or REMIC II or on the assets or transactions of either such REMIC,
      together with all incidental costs and expenses, to the extent none of the
      Trustee, the REMIC Administrator, the Master Servicer or the Special
      Servicer is liable therefor pursuant to Section 10.01(i); provided that a
      portion of such amounts shall be allocated pursuant to the 2005-C19
      Pooling and Servicing Agreement, the LB-UBS 2005-C3 Pooling and Servicing
      Agreement, the MSCI 2005-HQ6 Pooling and Servicing Agreement and the
      related Intercreditor Agreement if such costs relate to the AmericasMart
      Whole Loan, the 101 Avenue of the Americas Whole Loan or the U-Haul
      Portfolio Whole Loan;

            (vi) to pay the REMIC Administrator any amounts reimbursable to it
      pursuant to Section 10.01(e); provided that a portion of such amounts
      shall be allocated pursuant to the 2005-C19 Pooling and Servicing
      Agreement, the LB-UBS 2005-C3 Pooling and Servicing Agreement, the MSCI
      2005-HQ6 Pooling and Servicing Agreement and the related Intercreditor
      Agreement if such costs relate to the AmericasMart Whole Loan, the 101
      Avenue of the Americas Whole Loan or the U-Haul Portfolio Whole Loan;

            (vii) to pay to the Master Servicer any amounts deposited by the
      Master Servicer in the Distribution Account not required to be deposited
      therein; and

            (viii) to clear and terminate the Distribution Account at the
      termination of this Agreement pursuant to Section 9.01.

            Taxes imposed on REMIC I or REMIC II shall be allocated to the
related REMIC.

            (c) The Companion Paying Agent may, from time to time, make
withdrawals from the Companion Distribution Account as contemplated by Section
4.01(l).

            (d) The Trustee shall on each P&I Advance Date to occur in March of
each year, and in the event the final Distribution Date occurs in February or,
if such year is not a leap year, in January, on the P&I Advance Date to occur in
such February or January, withdraw from the Interest Reserve Account and deposit
into the Distribution Account in respect of each Interest Reserve Loan, an
amount equal to the aggregate of the Interest Reserve Amounts deposited into the
Interest Reserve Account pursuant to Section 3.04(c) during the immediately
preceding Collection Period and, if applicable, the second preceding Collection
Period and, if applicable, the related Collection Period.

            (e) The Paying Agent shall, on any Distribution Date, make
withdrawals from the Additional Interest Account to the extent required to make
the distributions of Additional Interest required by Section 4.01(b).

            (f) In the event that servicing advances (or, with respect to the
2005-C19 Serviced Mortgage Loan, principal and interest advances) have been made
with respect to the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced
Mortgage Loan or the MSCI 2005-HQ6 Serviced Mortgage Loan under the 2005-C19
Pooling and Servicing Agreement, the LB-UBS 2005-C3 Pooling and Servicing
Agreement or the MSCI 2005-HQ6 Pooling and Servicing Agreement, as the case may
be, by the 2005-C19 Master Servicer, the LB-UBS 2005-C3 Master Servicer or the
MSCI 2005-HQ6 Master Servicer, as the case may be, and in accordance with the
2005-C19 Pooling and Servicing Agreement, the LB-UBS 2005-C3 Pooling and
Servicing Agreement or the MSCI 2005-HQ6 Pooling and Servicing Agreement, as the
case may be, if a subsequent determination has been made that such advance
constitutes a nonrecoverable advance, the party that made such advance shall be
entitled to a reimbursement of such advance with interest thereon as set forth
in the 2005-C19 Pooling and Servicing Agreement, the LB-UBS 2005-C3 Pooling and
Servicing Agreement or the MSCI 2005-HQ6 Pooling and Servicing Agreement, as the
case may be, from general collections on all Mortgage Loans in the Certificate
Account (up to, with respect to a servicing advance, the AmericasMart Loan's,
the 101 Avenue of the Americas Loan's and the U-Hauls Portfolio Loan's pro rata
share of such advance, or if the amount of such pro rata share, together with
amounts available from collections in the certificate account created under the
2005-C19 Pooling and Servicing Agreement, the LB-UBS 2005-C3 Pooling and
Servicing Agreement or the MSCI 2005-HQ6 Pooling and Servicing Agreement, as the
case may be, is insufficient to reimburse the party that made such advance, then
up to the full amount of such advance and interest thereon) subject, in each
case, to the terms of the related Intercreditor Agreement.

            (g) The Paying Agent shall, on any Distribution Date, make
withdrawals from the Gain-On-Sale Reserve Account as contemplated by Section

            thereto;

                  (ii) out of interest amounts to make regularly scheduled
            payments of interest required to be paid to the Class A-3SF Swap
            Counterparty under the Class A-3SF Swap Contract as specified in
            Section 3.28(c), provided there is no Class A-3SF Swap Default;

                  (iii) to make distributions to the Holders of the Class A-3SF
            Certificates pursuant to Section 4.01; and

                  (iv) to clear and terminate the Class A-3SF Floating Rate
            Account pursuant to Section 9.01.

            (i) The Paying Agent shall make withdrawals from the Class A-MFL
Floating Rate Account in the following order of priority and only for the
following purposes:

                  (i) to withdraw amounts deposited in the Class A-MFL Floating
            Rate Account in error and pay such amounts to Persons entitled
            thereto;

                  (ii) out of interest amounts to make regularly scheduled
            payments of interest required to be paid to the Class A-MFL Swap
            Counterparty under the Class A-MFL Swap Contract as specified in
            Section 3.29(c), provided there is no Class A-MFL Swap Default;

                  (iii) to make distributions to the Holders of the Class A-MFL
            Certificates pursuant to Section 4.01; and

                  (iv) to clear and terminate the Class A-MFL Floating Rate

            Section 3.06 Investment of Funds in the Servicing Accounts,
Certificate Account, Class A-3SF Floating Rate Account, Class A-MFL Floating
Rate Account, Interest Reserve Account, Distribution Account, Companion
Distribution Account, Additional Interest Account, Gain-on-Sale Reserve Account
and REO Account.

            (a) The Master Servicer may direct in writing any depository
institution maintaining a Servicing Account, a Reserve Account or the
Certificate Account (each, for purposes of this Section 3.06, an "Investment
Account"); the Companion Paying Agent may direct in writing any depository
institution maintaining the Companion Distribution Account (also, for purposes
of this Section 3.06, an "Investment Account"); the Special Servicer may direct
in writing any depository institution maintaining the REO Account (also, for
purposes of this Section 3.06, an "Investment Account"); and the Trustee may
direct in writing any depository institution maintaining the Distribution
Account, the Class A-3SF Floating Rate Account, the Class A-MFL Floating Rate
Account, the Gain-on-Sale Reserve Account, the Interest Reserve Account or the
Additional Interest Account (also, for purposes of this Section 3.06, an
"Investment Account") to invest, or if it is such depository institution, may
itself invest, the funds held therein only in one or more Permitted Investments
bearing interest or sold at a discount, and maturing, unless payable on demand,
no later than the Business Day immediately preceding the next succeeding date on
which such funds are required to be withdrawn from such account pursuant to this
Agreement. Funds held in the Distribution Account, the Companion Distribution
Account, the Additional Interest Account, the Class A-3SF Floating Rate Account,
the Class A-MFL Floating Rate Account, the Interest Reserve Account and the
Gain-on-Sale Reserve Account may remain uninvested. In the event that the Master
Servicer shall have failed to give investment directions for any Servicing
Account, any Reserve Account or the Certificate Account (exclusive of any
accounts as are held by the Master Servicer) or the Special Servicer shall have
failed to give investment directions for the REO Account by 11:00 A.M. New York
time on any Business Day on which there may be uninvested cash, such funds held
in the REO Account shall be invested in securities described in clause (i) of
the definition of the term "Permitted Investments"; and such funds held in such
other accounts shall be invested in securities described in clause (v) of such
definition. All such Permitted Investments shall be held to maturity, unless
payable on demand. Any investment of funds in an Investment Account shall be
made in the name of the Trustee (in its capacity as such). The Master Servicer
on behalf of the Trustee for the benefit of Certificateholders (with respect to
Permitted Investments of amounts in the Servicing Accounts, the Reserve Accounts
or the Certificate Account), the Special Servicer on behalf of the Trustee for
the benefit of Certificateholders (with respect to Permitted Investments of
amounts in the REO Account) and the Trustee (with respect to Permitted
Investments of amounts in the Distribution Account, the Gain-on-Sale Reserve
Account, the Class A-3SF Floating Rate Account, the Class A-MFL Floating Rate
Account, the Interest Reserve Account or the Additional Interest Account) for
the benefit of the Certificateholders, and the Companion Paying Agent with
respect to the Companion Distribution Account, shall (and the Trustee hereby
designates the Master Servicer and the Special Servicer, with respect to any
Investment Account maintained by them, and itself, with respect to the
Distribution Account, the Additional Interest Account, the Interest Reserve
Account, the Class A-3SF Floating Rate Account, the Class A-MFL Floating Rate
Account and the Gain-on-Sale Reserve Account, as applicable, as the Person that
shall) maintain continuous possession of any Permitted Investment that is either
(i) a "certificated security", as such term is defined in the UCC, or (ii) other
property in which a secured party may perfect its security interest by
possession under the UCC or any other applicable law. Possession of any such
Permitted Investment by the Master Servicer, the Special Servicer or the Trustee
shall constitute possession by the Trustee, as secured party, for purposes of
Section 9-313 of the UCC and any other applicable law. If amounts on deposit in
an Investment Account are at any time invested in a Permitted Investment payable
on demand, the Master Servicer (in the case of the Certificate Account,
Servicing Accounts and Reserve Accounts), the Special Servicer (in the case of
the REO Account), the Trustee (with respect to Permitted Investments of amounts
in the Distribution Account, the Gain-on-Sale Reserve Account, the Class A-3SF
Floating Rate Account, the Class A-MFL Floating Rate Account, the Interest
Reserve Account and the Additional Interest Account) or the Companion Paying
Agent with respect to the Companion Distribution Account, shall:

            (x) consistent with any notice required to be given thereunder,
demand that payment thereon be made on the last day such Permitted Investment
may otherwise mature hereunder in an amount equal to the lesser of (1) all
amounts then payable thereunder and (2) the amount required to be withdrawn on
such date; and

            (y) demand payment of all amounts due thereunder promptly upon
determination by the Master Servicer, the Special Servicer or the Trustee, as
the case may be, that such Permitted Investment would not constitute a Permitted
Investment in respect of funds thereafter on deposit in the Investment Account.

            (b) Whether or not the Master Servicer directs the investment of
funds in any of the Servicing Accounts, the Reserve Accounts or the Certificate
Account, interest and investment income realized on funds deposited therein, to
the extent of the related Net Investment Earnings, if any, for each Collection
Period and, in the case of a Reserve Account or a Servicing Account, to the
extent not otherwise payable to the related Mortgagor in accordance with
applicable law or the related Mortgage Loan documents, shall be for the sole and
exclusive benefit of the Master Servicer and shall be subject to its withdrawal
in accordance with Section 3.03(a), 3.03(f) or 3.05(a), as applicable. Whether
or not the Special Servicer directs the investment of funds in the REO Account,
interest and investment income realized on funds deposited therein, to the
extent of the Net Investment Earnings, if any, for each Collection Period, shall
be for the sole and exclusive benefit of the Special Servicer and shall be
subject to its withdrawal in accordance with Section 3.16(b). Whether or not the
Trustee directs the investment of funds in the Distribution Account, the
Interest Reserve Account, the Class A-3SF Floating Rate Account, the Class A-MFL
Floating Rate Account, the Additional Interest Account or the Gain-on-Sale
Reserve Account, interest and investment income realized on funds deposited
therein, to the extent of the Net Investment Earnings, if any, for each related
Distribution Date, shall be for the sole and exclusive benefit of the Trustee
and shall be subject to its (or the Paying Agent's on its behalf) withdrawal in
accordance with Section 3.05(b). If any loss shall be incurred in respect of any
Permitted Investment on deposit in any Investment Account, the Master Servicer
(in the case of the Servicing Accounts, the Reserve Accounts and the Certificate
Account, excluding any accounts containing amounts invested solely for the
benefit of, and at the direction of, the Mortgagor under the terms of the
Mortgage Loan or applicable law), the Companion Paying Agent (in the case of the
Companion Distribution Account), the Special Servicer (in the case of the REO
Account) and the Trustee (with respect to Permitted Investments of amounts in
the Distribution Account, the Class A-3SF Floating Rate Account, the Class A-MFL
Floating Rate Account, the Additional Interest Account, the Interest Reserve
Account and the Gain-on-Sale Reserve Account) shall promptly deposit therein
from its own funds, without right of reimbursement, no later than, in the case
of the Master Servicer and Special Servicer, the end of the Collection Period
during which such loss was incurred and in the case of the Trustee, no later
than 12:00 noon, New York City time, on the Distribution Date, the amount of the
Net Investment Loss, if any, for such Collection Period or on such Distribution
Date; provided that none of the Master Servicer, the Special Servicer or the
Trustee shall be required to deposit any loss on an investment of funds in an
Investment Account if such loss is incurred solely as a result of the insolvency
of the federal or state chartered depository institution or trust company that
holds such Investment Account, so long as such depository institution or trust
company satisfied the qualifications set forth in the definition of Eligible
Account at the time such investment was made.

            (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of a payment due under any Permitted Investment, or
if a default occurs in any other performance required under any Permitted
Investment and the Trustee, the Special Servicer or the Master Servicer fails to
deposit any losses with respect to such Permitted Investment pursuant to Section
3.06(b), the Trustee may (or, in the event of a default by the Trustee, the
Master Servicer or Special Servicer shall) and, subject to Section 8.02, upon
the request of Holders of Certificates entitled to not less than 25% of the
Voting Rights allocated to any Class, shall take such action as may be
appropriate to enforce such payment or performance, including the institution
and prosecution of appropriate proceedings.

            (d) Notwithstanding the investment of funds held in any Investment
Account, for purposes of the calculations hereunder, including, without
limitation, the calculation of the Available Distribution Amount, the amounts so
invested shall be deemed to remain on deposit in such Investment Account.

            Section 3.07 Maintenance of Insurance Policies; Errors and Omissions
and Fidelity Coverage.

            (a) The Master Servicer (with respect to Mortgage Loans and
Companion Loans to the extent that the Trust Fund has an insurable interest, but
other than the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced
Mortgage Loan, the MSCI 2005-HQ6 Serviced Mortgage Loan and their related
Companion Loans) and the Special Servicer (with respect to REO Properties to the
extent that the Trust Fund has an insurable interest) shall, consistent with the
Servicing Standard, cause to be maintained for each Mortgaged Property all
insurance coverage as is required under the related Mortgage; provided that, if
and to the extent that any such Mortgage permits the holder thereof any
discretion (by way of consent, approval or otherwise) as to the insurance
coverage that the related Mortgagor is required to maintain, the Master Servicer
shall exercise such discretion in a manner consistent with the Servicing
Standard; provided, further, if and to the extent that a Mortgage so permits,
the related Mortgagor shall be required to exercise its reasonable best efforts
to obtain the required insurance coverage from Qualified Insurers and required
insurance coverage obtained by the Master Servicer shall be from Qualified
Insurers. REO Property with respect to the Non-Serviced Mortgage Loans is
excluded for all purposes of this Section 3.07. The cost of any such insurance
coverage obtained by either the Master Servicer or the Special Servicer shall be
a Servicing Advance to be paid by the Master Servicer pursuant to Section 3.03.
Whether or not the applicable Mortgage Loan documents require such insurance,
the Majority Subordinate Certificateholder may request that earthquake insurance
be secured for one or more Mortgaged Properties at the expense of the Majority
Subordinate Certificateholder. Subject to Section 3.17(a), the Special Servicer
shall also cause to be maintained for each REO Property no less insurance
coverage than was previously required of the Mortgagor under the related
Mortgage; provided that all such insurance shall be obtained from Qualified
Insurers. All such insurance policies maintained by the Master Servicer or the
Special Servicer (i) shall contain (if they insure against loss to property and
do not relate to an REO Property) a "standard" mortgagee clause, with loss
payable to the Trustee or the Master Servicer on behalf of the Trustee (in the
case of insurance maintained in respect of Mortgage Loans); (ii) shall be in the
name of the Special Servicer (in the case of insurance maintained in respect of
REO Properties), on behalf of the Trustee; (iii) shall be non-cancelable without
30 days' prior written notice to the insured party; (iv) shall include coverage
in an amount not less than the lesser of (x) the full replacement cost of the
improvements securing a Mortgaged Property or REO Property, as applicable, or
(y) the outstanding principal balance owing on the related Mortgage Loan or REO
Loan, as applicable, and in any event, the amount necessary to avoid the
operation of any co-insurance provisions; (v) shall include a replacement cost
endorsement providing no deduction for depreciation (unless such endorsement is
not permitted under the related Mortgage Loan documents); (vi) shall include
such other insurance, including, to the extent available at commercially
reasonable rates, earthquake insurance, where applicable, as required under the
applicable Mortgage or other Mortgage Loan document; and (vii) in each case such
insurance shall be issued by an insurer authorized under applicable law to issue
such insurance. Any amounts collected by the Master Servicer or the Special
Servicer under any such policies (other than amounts to be applied to the
restoration or repair of the related Mortgaged Property or REO Property or
amounts to be released to the related Mortgagor, in each case subject to the
rights of any tenants and ground lessors, as the case may be, and in each case
in accordance with the terms of the related Mortgage and the Servicing Standard)
shall be deposited in the Certificate Account, subject to withdrawal pursuant to
Section 3.05(a), in the case of amounts received in respect of a Mortgage Loan
or Companion Loan, or in the REO Account, subject to withdrawal pursuant to
Section 3.16(c), in the case of amounts received in respect of an REO Property.
Any cost incurred by the Master Servicer or the Special Servicer in maintaining
any such insurance shall not, for purposes hereof, including, without
limitation, calculating monthly distributions to Certificateholders, be added to
unpaid principal balance of the related Mortgage Loan, notwithstanding that the
terms of such Mortgage Loan or Companion Loans so permit.

            Notwithstanding the foregoing, the Master Servicer or Special
Servicer, as applicable, will not be required to maintain (and in the case of
the Special Servicer, with respect to any Specially Serviced Mortgage Loan), and
shall not cause a Mortgagor to be in default with respect to the failure of the
related Mortgagor to obtain, all-risk casualty insurance which does not contain
any carve-out for terrorist or similar acts, if and only if the Master Servicer
with respect to non-Specially Serviced Mortgage Loans or the Special Servicer
with respect to Specially Serviced Mortgage Loans, in consultation with the
Controlling Class Representative, and, with respect to each Co-Lender Loan
(other than the Non-Serviced Mortgage Loans), in consultation with the related
Companion Holder if required under the applicable Intercreditor Agreement, has
determined in accordance with the Servicing Standard that either (a) such
insurance is not available at any rate or (b) such insurance is not available at
commercially reasonably rates and that such hazards are not at the time commonly
insured against for properties similar to the Mortgaged Property and located in
or around the region in which such Mortgaged Property is located and the
Controlling Class Representative has approved the decision not to require the
borrower to maintain terrorism insurance (provided, that the decision of the
Controlling Class Representative to grant or withhold such consent shall be
disregarded by the Special Servicer if such consent or lack of consent would
cause the Master Servicer or the Special Servicer, as applicable, to violate the
Servicing Standard); provided, however, the Controlling Class Representative's
approval shall be deemed to have been given if it has not responded within five
Business Days of receipt of the Master Servicer's or the Special Servicer's
written recommendation and the information upon which such recommendation is
based; provided, further, that upon the Master Servicer's or the Special
Servicer's determination, as applicable, consistent with the Servicing Standard,
that exigent circumstances do not allow the Master Servicer or the Special
Servicer to consult with the Controlling Class Representative or Companion
Holder, if applicable, the Master Servicer or the Special Servicer, as
applicable, shall not be required to do so.

            (b) If the Master Servicer or the Special Servicer shall obtain and
maintain, or cause to be obtained and maintained, a blanket policy insuring
against hazard losses on all of the Mortgage Loans, Companion Loans and/or REO
Properties that it is required to service and administer, then, to the extent
such policy (i) is obtained from a Qualified Insurer and (ii) provides
protection equivalent to the individual policies otherwise required, the Master
Servicer or the Special Servicer, as the case may be, shall conclusively be
deemed to have satisfied its obligation to cause hazard insurance to be
maintained on the related Mortgaged Properties and/or REO Properties. Such
blanket policy may contain a deductible clause (not in excess of a customary
amount), in which case the Master Servicer or the Special Servicer, as
appropriate, shall, if there shall not have been maintained on the related
Mortgaged Property or REO Property a hazard insurance policy complying with the
requirements of Section 3.07(a), and there shall have been one or more losses
that would have been covered by such policy, promptly deposit into the
Certificate Account from its own funds the amount not otherwise payable under
the blanket policy because of such deductible clause. The Master Servicer or the
Special Servicer, as appropriate, shall prepare and present, on behalf of
itself, the Trustee and Certificateholders, claims under any such blanket policy
in a timely fashion in accordance with the terms of such policy.

            (c) Each of the Master Servicer and the Special Servicer shall at
all times during the term of this Agreement (or, in the case of the Special
Servicer, at all times during the term of this Agreement in which Specially
Serviced Mortgage Loans or REO Properties are part of the Trust Fund) keep in
force a fidelity bond with Qualified Insurers, such fidelity bond to be in such
form and amount as would permit it to be a qualified FNMA or FHLMC, whichever is
greater, seller-servicer of multifamily mortgage loans, or in such other form
and amount as would not cause the qualification, downgrading or withdrawal of
any rating assigned by any Rating Agency to the Certificates (as evidenced in
writing from each Rating Agency). Each of the Master Servicer and the Special
Servicer shall be deemed to have complied with the foregoing provision if an
Affiliate thereof has such fidelity bond coverage and, by the terms of such
fidelity bond, the coverage afforded thereunder extends to the Master Servicer
or the Special Servicer, as the case may be. Such fidelity bond shall provide
for ten days' written notice to the Trustee prior to any cancellation.

            Each of the Master Servicer and the Special Servicer shall at all
times during the term of this Agreement (or, in the case of the Special
Servicer, at all times during the term of this Agreement in which Specially
Serviced Mortgage Loans and/or REO Properties exist as part of the Trust Fund)
also keep in force with Qualified Insurers, a policy or policies of insurance
covering loss occasioned by the errors and omissions of its officers, employees
and agents in connection with its servicing obligations hereunder, which policy
or policies shall be in such form and amount as would permit it to be a
qualified FNMA seller-servicer of multifamily mortgage loans, or in such other
form and amount as would not cause the qualification, downgrade or withdrawal of
any rating assigned by any Rating Agency to the Certificates (as evidenced in
writing from each Rating Agency). Each of the Master Servicer and the Special
Servicer shall be deemed to have complied with the foregoing provisions if an
Affiliate thereof has such insurance and, by the terms of such policy or
policies, the coverage afforded thereunder extends to the Master Servicer or the
Special Servicer, as the case may be. Any such errors and omissions policy shall
provide for ten days' written notice to the Trustee prior to cancellation. The
Master Servicer and the Special Servicer shall each cause the Trustee to be an
additional loss payee on any policy currently in place or procured pursuant to
the requirements of this Section 3.07(c).

            For so long as the long-term debt obligations of the Master Servicer
or Special Servicer, as the case may be (or in the case of the initial Master
Servicer and Special Servicer, their respective direct or indirect parent), are
rated at least "A" or the equivalent by all of the Rating Agencies (or such
lower rating as will not result in qualification, downgrading or withdrawal of
the ratings then assigned to the Certificates, as evidenced in writing by the
Rating Agencies), such Person may self-insure with respect to the risks
described in this subsection.

            Section 3.08 Enforcement of Alienation Clauses.

            (a) Upon receipt of any request of a waiver in respect of a
due-on-sale or due-on-encumbrance provision, the Master Servicer, with respect
to Mortgage Loans (other than the Non-Serviced Mortgage Loans) that are not
Specially Serviced Mortgage Loans, and the Special Servicer, with respect to
Specially Serviced Mortgage Loans, shall promptly analyze such waiver, including
the preparation of written materials in connection with such analysis, and will
close the related transaction, subject to the consent rights (if any) of each
Companion Holder pursuant to the related Intercreditor Agreement as provided in
this Section 3.08. With respect to all Mortgage Loans other than Specially
Serviced Mortgage Loans and the Non-Serviced Mortgage Loans, the Master Servicer
or, in the case of Specially Serviced Mortgage Loans, the Special Servicer, on
behalf of the Trustee as the mortgagee of record, shall, to the extent permitted
by applicable law, enforce the restrictions contained in the related Mortgage on
transfers or further encumbrances of the related Mortgaged Property and on
transfers of interests in the related Mortgagor, unless following its receipt of
a request of a waiver in respect of a due-on-sale or due-on-encumbrance
provision the Master Servicer (with the written consent of the Special Servicer,
which consent shall be deemed given if not denied within the later of (a) 15
Business Days after the Special Servicer's receipt of the written recommendation
of the Master Servicer for such action and any additional information the
Special Servicer may reasonably request for the analysis of such request (such
recommendation and information may be delivered in an electronic format
reasonably acceptable to the Master Servicer and the Special Servicer) and (b)
five (5) Business Days after the Controlling Class Representative's receipt of
the written recommendation of the Special Servicer for such action and any
additional information the Controlling Class Representative may reasonably
request for the analysis of such request, which notice shall be given by the
Special Servicer no later than 10 Business Days after the commencement of the 15
Business Day period described in the preceding clause (a)) or the Special
Servicer (with the written consent of the Controlling Class Representative,
which consent shall be deemed given if not denied within five Business Days
after the Controlling Class Representative's receipt of the written
recommendation of the Special Servicer for such action and any additional
information the Controlling Class Representative may reasonably request for the
analysis of such request), as applicable, has determined, consistent with the
Servicing Standard, that the waiver of such restrictions would be in accordance
with the Servicing Standard. Promptly after the Master Servicer (with the
written consent of the Special Servicer to the extent required in the preceding
sentence) or the Special Servicer (with the written consent of the Controlling
Class Representative to the extent required in the preceding sentence), as
applicable, has made any such determination, the Master Servicer or the Special
Servicer shall deliver to the Trustee, the Rating Agencies and each other party
hereto an Officer's Certificate setting forth the basis for such determination.
Neither the Master Servicer nor the Special Servicer shall exercise (and the
Special Servicer shall not consent to) any such waiver in respect of a
due-on-encumbrance provision of any Mortgage Loan (i) with respect to which the
aggregate of the Stated Principal Balance of such Mortgage Loan and the Stated
Principal Balance of all other Mortgage Loans that are cross-collateralized,
cross-defaulted or have been made to Mortgagors affiliated with the Mortgagor on
such Mortgage Loan, are one of the ten largest Mortgage Loans or concentrations
of Mortgage Loans, as of the date of such waiver request, without receiving
prior written confirmation from Fitch, S&P and Moody's that such action would
not result in a downgrading, qualification or withdrawal of the ratings then
assigned to the Certificates or (ii) with respect to which (a) the aggregate of
the Stated Principal Balance of such Mortgage Loan and the Stated Principal
Balance of all other Mortgage Loans that are cross-collateralized,
cross-defaulted or have been made to Mortgagors affiliated with the Mortgagor on
such Mortgage Loan, is equal to or in excess of $20,000,000, (b) the aggregate
of the Stated Principal Balance of such Mortgage Loan and the Stated Principal
Balance of all other Mortgage Loans that are cross-collateralized,
cross-defaulted or have been made to Mortgagors affiliated with the Mortgagor on
such Mortgage Loan, are greater than 2% of the aggregate Stated Principal
Balance of all Mortgage Loans, (c) such Mortgage Loan is one of the ten largest
Mortgage Loans as of the date of the waiver (by Stated Principal Balance), or
(d) such Mortgage Loan has a Loan-to-Value Ratio (calculated to include the
additional indebtedness secured by any encumbrance) that is equal to or greater
than 85% and a Debt Service Coverage Ratio (calculated to include the additional
debt from any encumbrance) of 1.2x or less, without receiving a prior written
confirmation from S&P that such action would not result in a downgrading,
qualification or withdrawal of the ratings then assigned to the Certificates.
With respect to a waiver of a due-on-sale provision, neither the Master Servicer
nor the Special Servicer shall waive any such restriction without receiving
prior written confirmation from Fitch, Moody's and S&P that such action would
not result in a downgrading, qualification or withdrawal of the ratings then
assigned to the Certificates; provided that, if the Mortgage Loan (a) does not
have an aggregate Stated Principal Balance (including the Stated Principal
Balance of all other Mortgage Loans that are cross-collateralized,
cross-defaulted or have been made to Mortgagors affiliated with the Mortgagor on
such Mortgage Loan) equal to or in excess of $35,000,000 (or $25,000,000 with
respect to Moody's), (b) does not have an aggregate Stated Principal Balance
(including the Stated Principal Balance of all other Mortgage Loans that are
cross-collateralized, cross-defaulted or have been made to Mortgagors affiliated
with the Mortgagor on such Mortgage Loan) greater than 5% of the aggregate
Stated Principal Balance of all Mortgage Loans or (c) is not one of the ten
largest Mortgage Loans as of the date of the waiver (by Stated Principal
Balance), the Master Servicer or the Special Servicer, as applicable, may waive
such requirement without confirmation by S&P in accordance with the Servicing
Standard; and provided, further, that, if the Mortgage Loan does not meet the
criteria set forth in clause (ii) of the immediately preceding sentence, the
Master Servicer or Special Servicer, as applicable, may waive such requirement
without approval by S&P, Moody's or Fitch in accordance with the Servicing
Standard. With respect to each Co-Lender Loan, no waiver of a due-on-sale or
due-on-encumbrance provision will be effective unless the Master Servicer or
Special Servicer, as applicable, first consults with the related Subordinate
Companion Holder if required under the applicable Intercreditor Agreement.

            (b) Notwithstanding any other provisions of this Section 3.08, the
Master Servicer (with respect to Mortgage Loans other than Specially Serviced
Mortgage Loans and the Non-Serviced Mortgage Loans) (without the Special
Servicer's consent) or the Special Servicer (with respect to Specially Serviced
Mortgage Loans) may grant, without any Rating Agency confirmation as provided in
paragraph (a) above, a Mortgagor's request for consent to subject the related
Mortgaged Property to an easement or right-of-way for utilities, access,
parking, public improvements or another purpose, and may consent to
subordination of the related Mortgage Loan to such easement or right-of-way
provided the Master Servicer or the Special Servicer, as applicable, shall have
determined in accordance with the Servicing Standard that such easement or
right-of-way shall not materially interfere with the then-current use of the
related Mortgaged Property, or the security intended to be provided by such
Mortgage, the related Mortgagor's ability to repay the Mortgage Loan, or
materially or adversely affect the value of such Mortgaged Property or cause the
Mortgage Loan to cease to be a "qualified mortgage" for REMIC purposes.

            (c) Within ninety (90) days of the Closing Date, with respect to
each of the Mortgage Loans (other than the Non-Serviced Mortgage Loans) covered
by an environmental insurance policy, if any, the Master Servicer shall notify
the insurer under such environmental insurance policy and take all other action
necessary for the Trustee, on behalf of the Certificateholders, to be an insured
(and for the Master Servicer, on behalf of the Trust Fund, to make claims) under
such environmental insurance policy. In the event that the Master Servicer has
actual knowledge of any event (an "Insured Environmental Event") giving rise to
a claim under any environmental insurance policy in respect of any Mortgage Loan
covered thereby, the Master Servicer shall, in accordance with the terms of such
environmental insurance policy and the Servicing Standard, timely make a claim
thereunder with the appropriate insurer and shall take such other actions in
accordance with the Servicing Standard which are necessary under such
environmental insurance policy in order to realize the full value thereof for
the benefit of the Certificateholders. Any legal fees, premiums or other
out-of-pocket costs incurred in accordance with the Servicing Standard in
connection with any such claim under an environmental insurance policy shall be
paid by the Master Servicer and shall be reimbursable to it as a Servicing
Advance. With respect to each environmental insurance policy that relates to one
or more Mortgage Loans (other than the Non-Serviced Mortgage Loans), the Master
Servicer shall review and familiarize itself with the terms and conditions
relating to enforcement of claims and shall monitor the dates by which any claim
must be made or any action must be taken under such policy to realize the full
value thereof for the benefit of the Certificateholders in the event the Master
Servicer has actual knowledge of an Insured Environmental Event giving rise to a
claim under such policy.

            In the event that the Master Servicer receives notice of any
termination of any environmental insurance policy that relates to one or more
Mortgage Loans (other than the Non-Serviced Mortgage Loans), the Master Servicer
shall, within five Business Days after receipt of such notice, notify the
Special Servicer, the Controlling Class Representative, the related Companion
Holder (in the case of a Co-Lender Loan), the Rating Agencies and the Trustee of
such termination in writing. Upon receipt of such notice, the Master Servicer
with respect to non-Specially Serviced Mortgage Loans (other than the
Non-Serviced Mortgage Loans), and the Special Servicer with respect to Specially
Serviced Mortgage Loans, shall address such termination in accordance with
Section 3.07(a) in the same manner as it would the termination of any other
Insurance Policy required under the related Mortgage Loan documents. Any legal
fees, premiums or other out-of-pocket costs incurred in accordance with the
Servicing Standard in connection with a resolution of such termination of an
environmental insurance policy shall be paid by the Master Servicer and shall be
reimbursable to it as a Servicing Advance.

            (d) For the avoidance of doubt, any servicing obligation set forth
under this Section 3.08 of the Master Servicer or Special Servicer, as
applicable, for any Pari Passu Mortgage Loan shall also apply to the related
Pari Passu Companion Loan (other than the Non-Serviced Companion Loans).

            Section 3.09 Realization Upon Defaulted Mortgage Loans; Required
Appraisals.

            (a) The Special Servicer shall, subject to Sections 3.09(b) through
3.09(d) and Section 6.11, exercise reasonable efforts, consistent with the
Servicing Standard, to foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Mortgage Loans or Companion Loans
(other than the Non-Serviced Mortgage Loans and their related Companion Loans)
as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments, including,
without limitation, pursuant to Section 3.20. Subject to the second paragraph of
Section 3.03(c), the Master Servicer shall advance all costs and expenses (other
than costs or expenses that would, if incurred, constitute a Nonrecoverable
Servicing Advance) incurred by the Special Servicer in any such proceedings, and
shall be entitled to reimbursement therefor as provided in Section 3.05(a).
Nothing contained in this Section 3.09 shall be construed so as to require the
Special Servicer, on behalf of the Trust Fund, to make a bid on any Mortgaged
Property at a foreclosure sale or similar proceeding that is in excess of the
fair market value of such property, as determined by the Special Servicer in
accordance with the Servicing Standard and in its reasonable and good faith
judgment taking into account, as applicable, among other factors, the period and
amount of any delinquency on the affected Mortgage Loan or Companion Loan, the
occupancy level and physical condition of the Mortgaged Property or REO
Property, the state of the local economy, the obligation to dispose of any REO
Property within the time period specified in Section 3.16(a) and the results of
any appraisal obtained pursuant to the following sentence, all such bids to be
made in a manner consistent with the Servicing Standard. If and when the Master
Servicer or the Special Servicer deems it necessary and prudent for purposes of
establishing the fair market value of any Mortgaged Property securing a
Defaulted Mortgage Loan or defaulted Companion Loan, whether for purposes of
bidding at foreclosure or otherwise, it may, at the expense of the Trust Fund,
have an appraisal performed with respect to such property by an Independent
Appraiser or other expert in real estate matters; which appraisal shall take
into account, as applicable, among other factors, the period and amount of any
delinquency on the affected Mortgage Loan, the occupancy level and physical
condition of the Mortgaged Property or REO Property, the state of the local
economy and the obligation to dispose of any REO Property within the time period
specified in Section 3.16(a), including without limitation, any environmental,
engineering or other third party reports available, and other factors that a
prudent real estate appraiser would consider.

            With respect to each Required Appraisal Mortgage Loan (other than
the Non-Serviced Mortgage Loans), the Special Servicer will be required to
obtain a Required Appraisal (or with respect to any Mortgage Loan with an
outstanding principal balance less than $2,000,000, an internal valuation
performed by the Special Servicer) within 60 days of a Mortgage Loan becoming a
Required Appraisal Mortgage Loan (unless an appraisal meeting the requirements
of a Required Appraisal was obtained for such Required Appraisal Mortgage Loan
within the prior 12 months and the Special Servicer has no actual knowledge of a
material adverse change in the condition of the related Mortgaged Property in
which case such appraisal may be a letter update of the Required Appraisal) and
thereafter shall obtain a Required Appraisal (or with respect to any Mortgage
Loan with an outstanding principal balance less than $2,000,000, and in lieu of
an Appraisal, an internal valuation performed by the Special Servicer) once
every 12 months (or sooner if the Special Servicer has actual knowledge of a
material adverse change in the condition of the related Mortgaged Property) if
such Mortgage Loan remains a Required Appraisal Mortgage Loan. The Special
Servicer will deliver a copy of each Required Appraisal (or letter update or
internal valuation) to the Master Servicer, the Controlling Class Representative
and the Trustee (and, if such Required Appraisal Mortgage Loan is a Co-Lender
Loan, to the related Companion Holder) within 10 Business Days of obtaining such
Required Appraisal (or letter update or internal valuation). Subject to the
second paragraph of Section 3.03(c), the Master Servicer shall advance the cost
of such Required Appraisal; provided, however, that such expense will be subject
to reimbursement to the Master Servicer as a Servicing Advance out of the
Certificate Account pursuant to Section 3.05(a)(vi) and 3.05(a)(vii).

            Notwithstanding the foregoing, in no event shall the Master Servicer
or the Special Servicer obtain an appraisal of a Companion Loan pursuant to this
Section 3.09(a) to the extent the related Co-Lender Loan has been paid in full.

            (b) The Special Servicer shall not acquire any personal property
pursuant to this Section 3.09 unless either:

                  (i) such personal property is incident to real property
            (within the meaning of Section 856(e)(1) of the Code) so acquired by
            the Special Servicer; or

                  (ii) the Special Servicer shall have obtained an Opinion of
            Counsel (the cost of which may be withdrawn from the Certificate
            Account pursuant to Section 3.05(a)) to the effect that the holding
            of such personal property as part of the Trust Fund (to the extent
            not allocable to a Companion Loan) will not cause the imposition of
            a tax on either of REMIC I or REMIC II under the REMIC Provisions or
            cause either of REMIC I or REMIC II to fail to qualify as a REMIC at
            any time that any Certificate is outstanding.

            (c) Notwithstanding the foregoing provisions of this Section 3.09,
neither the Master Servicer nor the Special Servicer shall, on behalf of the
Trustee (which may include through a single member limited liability company
owned by the Trust), initiate foreclosure proceedings, obtain title to a
Mortgaged Property by deed in lieu of foreclosure or otherwise, or take any
other action with respect to any Mortgaged Property, if, as a result of any such
action, the Trustee, on behalf of the Certificateholders, could, in the
reasonable judgment of the Master Servicer or the Special Servicer, as the case
may be, made in accordance with the Servicing Standard, be considered to hold
title to, to be a "mortgagee-in-possession" of, or to be an "owner" or
"operator" of such Mortgaged Property within the meaning of CERCLA or any
comparable law (a "potentially responsible party"), unless (as evidenced by an
Officer's Certificate to such effect delivered to the Trustee that shall specify
all of the bases for such determination) the Special Servicer has previously
determined in accordance with the Servicing Standard, and based on an
Environmental Assessment of such Mortgaged Property performed by an Independent
Person who regularly conducts Environmental Assessments and performed within six
months prior to any such acquisition of title or other action (a copy of which
Environmental Assessment shall be delivered to the Trustee, the Controlling
Class Representative and the Master Servicer), that:

                  (i) the Mortgaged Property is in compliance with applicable
            environmental laws and regulations or, if not, that it would
            maximize the recovery to the Certificateholders on a present value
            basis (the relevant discounting of anticipated collections that will
            be distributable to Certificateholders to be performed at the
            related Net Mortgage Rate) to acquire title to or possession of the
            Mortgaged Property and to take such actions as are necessary to
            bring the Mortgaged Property into compliance therewith in all
            material respects; and

                  (ii) there are no circumstances or conditions present at the
            Mortgaged Property relating to the use, management or disposal of
            Hazardous Materials for which investigation, testing, monitoring,
            containment, clean-up or remediation could be required under any
            applicable environmental laws and regulations or, if such
            circumstances or conditions are present for which any such action
            could reasonably be expected to be required, that it would maximize
            the recovery to the Certificateholders on a present value basis (the
            relevant discounting of anticipated collections that will be
            distributable to Certificateholders to be performed at the related
            Net Mortgage Rate) to acquire title to or possession of the
            Mortgaged Property and to take such actions with respect to the
            affected Mortgaged Property.

            The Special Servicer shall undertake, in good faith, reasonable
efforts to make the determination referred to in the preceding paragraph and may
conclusively rely on the Environmental Assessment referred to above in making
such determination. The cost of any such Environmental Assessment, as well as
the cost of any remedial, corrective or other further action contemplated by
clause (i) and/or clause (ii) of the preceding paragraph shall be at the expense
of the Trust Fund (except to the extent that such Additional Trust Fund Expense
is payable out of the proceeds of any Companion Loan pursuant to the related
Intercreditor Agreement and this Agreement); and if any such Environmental
Assessment so warrants, the Special Servicer shall perform such additional
environmental testing as it deems necessary and prudent to determine whether the
conditions described in clauses (i) and (ii) of the preceding paragraph have
been satisfied, the cost of which shall be at the expense of the Trust Fund.

            (d) If the environmental testing contemplated by Section 3.09(c)
above establishes that any of the conditions set forth in clauses (i) and (ii)
thereof has not been satisfied with respect to any Mortgaged Property securing a
Defaulted Mortgage Loan (other than the Non-Serviced Mortgage Loans) and there
is no breach of a representation or warranty requiring repurchase under the
applicable Mortgage Loan Purchase Agreement, the Special Servicer shall take
such action as is in accordance with the Servicing Standard (other than
proceeding against the Mortgaged Property) and, at such time as it deems
appropriate, may, on behalf of the Trustee, release all or a portion of such
Mortgaged Property from the lien of the related Mortgage; provided that, if such
Mortgage Loan has a then outstanding principal balance of greater than
$1,000,000, then prior to the release of all or a portion of the related
Mortgaged Property from the lien of the related Mortgage, (i) the Special
Servicer shall have notified the Rating Agencies, the Trustee, the Controlling
Class Representative and the Master Servicer in writing of its intention to so
release all or a portion of such Mortgaged Property and the bases for such
intention, (ii) the Trustee shall have notified the Certificateholders in
writing of the Special Servicer's intention to so release all or a portion of
such Mortgaged Property and (iii) the Holders of Certificates entitled to a
majority of the Voting Rights shall have consented to such release within 30
days of the Trustee's distributing such notice (failure to respond by the end of
such 30-day period being deemed consent).

            (e) The Special Servicer shall report to the Master Servicer, the
Controlling Class Representative and the Trustee monthly in writing as to any
actions taken by the Special Servicer with respect to any Mortgaged Property
that represents security for a Defaulted Mortgage Loan as to which the
environmental testing contemplated in Section 3.09(c) above has revealed that
any of the conditions set forth in clauses (i) and (ii) thereof has not been
satisfied, in each case until the earlier to occur of satisfaction of all such
conditions and release of the lien of the related Mortgage on such Mortgaged
Property.

            (f) The Special Servicer shall have the right to determine, in
accordance with the Servicing Standard, the advisability of seeking to obtain a
deficiency judgment if the state in which the Mortgaged Property is located and
the terms of the Mortgage Loan or Companion Loan permit such an action and
shall, in accordance with the Servicing Standard, seek such deficiency judgment
if it deems advisable.

            (g) The Master Servicer shall, with the reasonable cooperation of
the Special Servicer, prepare and file information returns with respect to
reports of foreclosures and abandonments of any Mortgaged Property and the
information returns relating to any Mortgaged Property securing a Mortgage Loan
(other than the Non-Serviced Mortgage Loans) and, if applicable, Companion Loan
required by Sections 6050J and 6050P of the Code and each year deliver to the
Trustee an Officer's Certificate stating that such reports have been filed. Such
reports shall be in form and substance sufficient to meet the reporting
requirements imposed by Sections 6050J and 6050P of the Code.

            (h) The Special Servicer shall maintain accurate records, prepared
by a Servicing Officer, of each Final Recovery Determination in respect of any
Mortgage Loan, Companion Loan or REO Property (other than with respect to the
Non-Serviced Mortgage Loans) and the basis thereof. Each Final Recovery
Determination shall be evidenced by an Officer's Certificate (together with the
basis and back-up documentation for the determination) delivered to the Trustee,
the Controlling Class Representative and the Master Servicer no later than the
third Business Day following such Final Recovery Determination.

            (i) Upon reasonable request of the Master Servicer, the Special
Servicer shall deliver to it and the related Sub-Servicer any other information
and copies of any other documents in its possession with respect to a Specially
Serviced Mortgage Loan or the related Mortgaged Property.

            Section 3.10 Trustee and Custodian to Cooperate; Release of Mortgage
Files.

            (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer of a notification that payment in full shall be escrowed in
a manner customary for such purposes, the Master Servicer shall promptly notify
the Trustee in writing, who shall release or cause the related Custodian to
release, by a certification (which certification shall be in the form of a
Request for Release in the form of Exhibit D-1 attached hereto and shall be
accompanied by the form of a release or discharge and shall include a statement
to the effect that all amounts received or to be received in connection with
such payment which are required to be deposited in the Certificate Account
pursuant to Section 3.04(a) have been or will be so deposited) of a Servicing
Officer (a copy of which certification shall be delivered to the Special
Servicer) and shall request delivery to it of the related Mortgage File. Upon
receipt of such certification and request, the Trustee shall release, or cause
any related Custodian to release, the related Mortgage File to the Master
Servicer and shall deliver to the Master Servicer such release or discharge,
duly executed. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Certificate
Account or the Distribution Account.

            (b) If from time to time, and as appropriate for servicing or
foreclosure of any Mortgage Loan (including any related Companion Loan), the
Master Servicer or the Special Servicer shall otherwise require any Mortgage
File (or any portion thereof), the Trustee, upon request of the Master Servicer
and receipt from the Master Servicer of a Request for Release in the form of
Exhibit D-1 attached hereto signed by a Servicing Officer thereof, or upon
request of the Special Servicer and receipt from the Special Servicer of a
Request for Release in the form of Exhibit D-2 attached hereto, shall release,
or cause any related Custodian to release, such Mortgage File (or portion
thereof) to the Master Servicer or the Special Servicer, as the case may be.
Upon return of such Mortgage File (or portion thereof) to the Trustee or related
Custodian, or the delivery to the Trustee of a certificate of a Servicing
Officer of the Special Servicer stating that such Mortgage Loan was liquidated
and that all amounts received or to be received in connection with such
liquidation that are required to be deposited into the Certificate Account
pursuant to Section 3.04(a) have been or will be so deposited, or that such
Mortgage Loan has become an REO Property, a copy of the Request for Release
shall be released by the Trustee or related Custodian to the Master Servicer or
the Special Servicer, as applicable.

            (c) Within seven Business Days (or within such shorter period (but
no less than three Business Days) as execution and delivery can reasonably be
accomplished if the Special Servicer notifies the Trustee of an exigency) of the
Special Servicer's request therefor, the Trustee shall execute and deliver to
the Special Servicer (or the Special Servicer may, subject to Section 3.01(b),
execute and deliver in the name of the Trustee based on a limited power of
attorney issued in favor of the Special Servicer pursuant to Section 3.01(b)),
in the form supplied to the Trustee, any court pleadings, requests for trustee's
sale or other documents stated by the Special Servicer to be reasonably
necessary to the foreclosure or trustee's sale in respect of a Mortgaged
Property or REO Property or to any legal action brought to obtain judgment
against any Mortgagor on the Mortgage Note (including any note evidencing a
related Companion Loan) or Mortgage or to obtain a deficiency judgment, or to
enforce any other remedies or rights provided by the Mortgage Note or Mortgage
or otherwise available at law or in equity or to defend any legal action or
counterclaim filed against the Trust Fund, the Master Servicer or the Special
Servicer. Together with such documents or pleadings, the Special Servicer shall
deliver to the Trustee a certificate of a Servicing Officer requesting that such
pleadings or documents be executed by the Trustee and certifying as to the
reason such documents or pleadings are required and that the execution and
delivery thereof by the Trustee will not invalidate or otherwise affect the lien
of the Mortgage, except for the termination of such a lien upon completion of
the foreclosure or trustee's sale.

            Section 3.11 Servicing Compensation.

            (a) As compensation for its activities hereunder, the Master
Servicer shall be entitled to receive the Master Servicing Fee with respect to
each Mortgage Loan (including each Specially Serviced Mortgage Loan) and REO
Loan. No Master Servicing Fee shall be payable with respect to any Companion
Loan unless such fee is expressly set forth in the related Intercreditor
Agreement. As to each such Mortgage Loan and REO Loan, the Master Servicing Fee
shall accrue at the related Master Servicing Fee Rate and on the same principal
amount respecting which the related interest payment due on such Mortgage Loan
or deemed to be due on such REO Loan is computed and calculated on the basis of
a 360-day year consisting of twelve 30-day months (or, in the event of a
Principal Prepayment in full or other Liquidation Event with respect to a
Mortgage Loan or REO Loan, on the basis of the actual number of days to elapse
from and including the related Due Date to but excluding the date of such
Principal Prepayment or Liquidation Event in a month consisting of 30 days). The
Master Servicing Fee with respect to each Non-Serviced Mortgage Loan will be as
set forth on the Mortgage Loan Schedule. The Master Servicing Fee with respect
to any Mortgage Loan or REO Loan shall cease to accrue if a Liquidation Event
occurs in respect thereof. Earned but unpaid Master Servicing Fees shall be
payable monthly, on a loan-by-loan basis, from payments of interest on each
Mortgage Loan and REO Revenues allocable as interest on each REO Loan. The
Master Servicer shall be entitled to recover unpaid Master Servicing Fees in
respect of any Mortgage Loan or REO Loan out of that portion of related
Insurance Proceeds or Liquidation Proceeds allocable as recoveries of interest,
to the extent permitted by Section 3.05(a)(iii) and otherwise as provided in
Section 3.05(a)(vii). The right to receive the Master Servicing Fee may not be
transferred in whole or in part except in connection with the transfer of all of
the Master Servicer's responsibilities and obligations under this Agreement.

            (b) Additional servicing compensation in the form of: (i) all late
payment charges, Penalty Interest, assumption application fees if the related
assumption is completed, modification fees for modifications to Mortgage Loans
or Companion Loans that are not Specially Serviced Mortgage Loans made by the
Master Servicer pursuant to Section 3.20(i), defeasance fees, charges for
beneficiary statements or demands, amounts collected for checks returned for
insufficient funds and any similar fees (excluding Prepayment Premiums or Yield
Maintenance Charges), in each case to the extent actually paid by a Mortgagor
with respect to a Mortgage Loan or Companion Loan and, with respect to late
payment charges and penalty charges, accrued during the time that such Mortgage
Loan or Companion Loan was not a Specially Serviced Mortgage Loan, and (ii)
fifty percent (50%) of (A) any assumption fees and (B) any assumption
application fees if the related assumption fails to be completed, in each case
to the extent actually paid by a Mortgagor with respect to any Mortgage Loan or
Companion Loan if such Mortgage Loan or Companion Loan is not a Specially
Serviced Mortgage Loan, may be retained by the Master Servicer and are not
required to be deposited in the Certificate Account; provided that the Master
Servicer's right to receive late payment charges and Penalty Interest pursuant
to clause (i) above shall be limited to the portion of such items that have not
been applied to pay interest on Advances as provided in Sections 3.03(d) and
4.03(d) or Additional Trust Fund Expenses (other than Special Servicing Fees,
Workout Fees and/or Liquidation Fees) or interest on Advances pursuant to this
Section 3.11(b). To the extent the Master Servicer or the Special Servicer
receives late payment charges or Penalty Interest on a Mortgage Loan for which
interest on Advances or Additional Trust Fund Expenses (other than Special
Servicing Fees, Workout Fees and/or Liquidation Fees) related to such Mortgage
Loan and not previously reimbursed to the Trust Fund, the Master Servicer shall
deposit in the Certificate Account, on or prior to the P&I Advance Date
following the collection of such late payment charges or Penalty Interest, an
amount equal to the lesser of (i) the amount of late payment charges or Penalty
Interest received on such Mortgage Loan or (ii) the sum of the amount of
interest paid to the Master Servicer on Advances related to such Mortgage Loan
since the Closing Date for which the Trust Fund has not been previously
reimbursed and the amount of Additional Trust Fund Expenses (other than Special
Servicing Fees, Workout Fees and/or Liquidation Fees) related to such Mortgage
Loan incurred since the Closing Date and not previously reimbursed to the Trust
Fund. To the extent that the Master Servicer is not entitled to late payment
charges or Penalty Interest pursuant to the immediately preceding sentence, the
Master Servicer shall deposit such late payment charges and Penalty Interest in
the Certificate Account. Penalty Interest or late payment charges in respect of
any Mortgage Loan or Companion Loan which has accrued during the period when the
related Mortgage Loan or Companion Loan is not a Specially Serviced Mortgage
Loan shall be additional compensation to the Master Servicer even if collected
during the period when the related Mortgage Loan or Companion Loan is a
Specially Serviced Mortgage Loan. The Master Servicer shall also be entitled to
additional servicing compensation in the form of (i) Prepayment Interest
Excesses; (ii) interest or other income earned on deposits in the Certificate
Account and the Interest Reserve Account, in accordance with Section 3.06(b)
(but only to the extent of the Net Investment Earnings, if any, with respect to
such account for each Collection Period), and (iii) to the extent not required
to be paid to any Mortgagor under applicable law or the terms of the related
Mortgage Loan or Companion Loan, any interest or other income earned on deposits
in the Reserve Accounts and Servicing Accounts maintained thereby.

            The Master Servicer shall be required to pay out of its own funds
all expenses incurred by it in connection with its servicing activities
hereunder (including, without limitation, payment of any amounts due and owing
to any of its Sub-Servicers and the premiums for any blanket policy insuring
against hazard losses pursuant to Section 3.07(b)), if and to the extent such
expenses are not payable directly out of the Certificate Account, and the Master
Servicer shall not be entitled to reimbursement therefor except as expressly
provided in this Agreement. The Master Servicer shall not waive or agree to any
discount of any portion of assumption fees to which the Special Servicer is
entitled.

            (c) As compensation for its activities hereunder, the Special
Servicer shall be entitled to receive the Special Servicing Fee with respect to
each Specially Serviced Mortgage Loan and each REO Loan (other than the 2005-C19
Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan, the MSCI
2005-HQ6 Serviced Mortgage Loan and related REO Loans). As to each Specially
Serviced Mortgage Loan and REO Loan, the Special Servicing Fee shall accrue at
the Special Servicing Fee Rate and on the same principal amount respecting which
the related interest payment due on such Specially Serviced Mortgage Loan or
deemed to be due on such REO Loan is computed and calculated on the basis of a
360-day year consisting of twelve 30-day months (or, in the event of a Principal
Prepayment in full or other Liquidation Event with respect to a Mortgage Loan or
REO Loan, on the basis of the actual number of days to elapse from and including
the related Due Date to but excluding the date of such Principal Prepayment or
Liquidation Event in a month consisting of 30 days). The Special Servicing Fee
with respect to any Specially Serviced Mortgage Loan or REO Loan shall cease to
accrue as of the date a Liquidation Event occurs in respect thereof or it
becomes a Corrected Mortgage Loan. Earned but unpaid Special Servicing Fees
shall be payable monthly out of general collections on the Mortgage Loans,
Companion Loans and any REO Properties on deposit in the Certificate Account
pursuant to Section 3.05(a).

            As further compensation for its activities hereunder, the Special
Servicer shall be entitled to receive the Workout Fee with respect to each
Corrected Mortgage Loan, so long as such loan remains a Corrected Mortgage Loan.
As to each Corrected Mortgage Loan, the Workout Fee shall be payable out of, and
shall be calculated by application of the Workout Fee Rate to, each collection
of interest (other than Additional Interest and Penalty Interest) and principal
received on such Mortgage Loan or Companion Loan for so long as it remains a
Corrected Mortgage Loan (net of any portion of such collection payable or
reimbursable to the Master Servicer, the Special Servicer, or the Trustee for
any related unpaid or unreimbursed Master Servicing Fees and/or Advances)
received on such Mortgage Loan or Companion Loan for so long as it remains a
Corrected Mortgage Loan. The Workout Fee with respect to any Corrected Mortgage
Loan will cease to be payable if a Servicing Transfer Event occurs with respect
thereto or if the related Mortgaged Property becomes an REO Property; provided
that a new Workout Fee would become payable if and when such Mortgage Loan and,
if applicable, Companion Loan again became a Corrected Mortgage Loan. If the
Special Servicer is terminated or resigns, it will retain the right to receive
any and all Workout Fees payable with respect to any Specially Serviced Mortgage
Loan that became a Corrected Mortgage Loan during the period that it acted as
Special Servicer and remained a Corrected Mortgage Loan at the time of its
termination or resignation or if the Special Servicer resolved the circumstances
and/or conditions (including by way of a modification of the related Mortgage
Loan documents) causing the Mortgage Loan to be a Specially Serviced Mortgage
Loan, but the Mortgage Loan had not as of the time the Special Servicer is
terminated or resigns become a Corrected Mortgage Loan because the related
borrower had not made three consecutive monthly debt service payments (but made
the most recent monthly debt service payment prior to the termination of the
Special Servicer) and subsequently becomes a Corrected Mortgage Loan as a result
of making three such consecutive payments. The successor Special Servicer will
not be entitled to any portion of those Workout Fees.

            In addition, with respect to each Specially Serviced Mortgage Loan
and REO Loan or Mortgage Loan subject to repurchase by the applicable Mortgage
Loan Seller (to the extent such Mortgage Loan was not repurchased within the
cure period specified in the related Mortgage Loan Purchase Agreement) (or
Qualified Substitute Mortgage Loan substituted in lieu thereof), the Special
Servicer shall be entitled to the Liquidation Fee payable out of, and calculated
by application of the Liquidation Fee Rate to, all amounts (whether in the form
of payments of Liquidation Proceeds or REO Revenues or a full or discounted
payoff by the Mortgagor) received in respect of such Mortgage Loan or Companion
Loan (or, in the case of an REO Loan, in respect of the related REO Property)
and allocable as a full or partial recovery of principal, interest and expenses
in accordance with Section 3.02(b) or the definition of "REO Loan," as
applicable; provided that no Liquidation Fee shall be payable in connection
with, or out of (i) Insurance Proceeds and (ii) Liquidation Proceeds resulting
from the purchase of any Mortgage Loan or REO Property by a Mortgage Loan Seller
pursuant to the applicable Mortgage Loan Purchase Agreement if purchased within
the cure period set forth in Section 3(c) of such Mortgage Loan Purchase
Agreement, by the Majority Subordinate Certificateholder, the Companion Holder,
or the Special Servicer pursuant to Section 3.18(c), Section 3.18(d), Section
3.18(e), Section 3.18(h) or by the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder or the purchasing Certificateholder
pursuant to Section 9.01, or any mezzanine lender pursuant to the related
mezzanine intercreditor agreement if purchased by the mezzanine lender within 90
days of the related Mortgage Loan becoming a Specially Serviced Mortgage Loan;
and (iii) Liquidation Proceeds resulting from the remittance by the related
Mortgage Loan Seller pursuant to Section 2.03 (if remitted within the cure
period set forth for repurchase in the related Mortgage Loan Purchase
Agreement); and provided, further, that no Liquidation Fee shall be payable (i)
in connection with a Periodic Payment received in connection with such Mortgage
Loan or (ii) to the extent a Workout Fee is payable concerning the Liquidation
Proceeds.

            The Special Servicer's right to receive the Special Servicing Fee,
the Workout Fee and the Liquidation Fee may not be transferred in whole or in
part except in connection with the transfer of all of the Special Servicer's
responsibilities and obligations under Sections 6.02, 6.04 and 6.09.

            (d) Additional servicing compensation in the form of: (i) all late
payment charges, Penalty Interest received on or with respect to Specially
Serviced Mortgage Loans actually collected that, with respect to late payment
charges and penalty charges, accrued during the time that the related Mortgage
Loan was a Specially Serviced Mortgage Loan, (ii) one hundred percent (100%) of
any assumption application fees and assumption fees with respect to any
Specially Serviced Mortgage Loan and fifty percent (50%) of (A) any assumption
fees and (B) any assumption application fees if the related assumption fails to
be completed with respect to any Mortgage Loan or Companion Loan if such
Mortgage Loan or Companion Loan is not a Specially Serviced Mortgage Loan, in
each case to the extent actually paid by a Mortgagor, and (iii) modification
fees collected on all Mortgage Loans or Companion Loans (other than
modifications made by the Master Servicer pursuant to Section 3.20(i)), in each
case to the extent actually paid by the related Mortgagor, shall be retained by
the Special Servicer or promptly paid to the Special Servicer by the Master
Servicer and shall not be required to be deposited in the Certificate Account;
provided that the Special Servicer's right to receive late payment charges and
Penalty Interest pursuant to clause (i) above shall be limited to the portion of
such items that have not been applied to pay interest on Advances and property
inspection costs in respect of the related Mortgage Loan as provided in Sections
3.03(d), 3.12(a) and 4.03(d) or Additional Trust Fund Expenses (other than
Special Servicing Fees, Workout Fees and/or Liquidation Fees) pursuant to this
Section 3.11(d). To the extent the Master Servicer or the Special Servicer
receives late payment charges or Penalty Interest on a Mortgage Loan for which
interest on Advances or Additional Trust Fund Expenses (other than Special
Servicing Fees, Workout Fees and/or Liquidation Fees) related to such Mortgage
Loan and not previously reimbursed to the Trust Fund, the Special Servicer shall
transfer to the Master Servicer for deposit in the Certificate Account, on or
prior to the P&I Advance Date following the collection of such late payment
charges or Penalty Interest, an amount equal to the lesser of (i) the amount of
late payment charges or Penalty Interest received on such Mortgage Loan or (ii)
the sum of the amount of interest paid to the Master Servicer on Advances
related to such Mortgage Loan incurred since the Closing Date for which the
Trust Fund has not been previously reimbursed and the amount of Additional Trust
Fund Expenses (other than Special Servicing Fees, Workout Fees and/or
Liquidation Fees) related to such Mortgage Loan since the Closing Date and not
previously reimbursed to the Trust Fund. To the extent that the Special Servicer
is not entitled to late payment charges or Penalty Interest pursuant to the
immediately preceding sentence, the Special Servicer shall promptly transfer
such late payment charges and Penalty Interest to the Master Servicer who shall
deposit such late payment charges and Penalty Interest in the Certificate
Account. The Special Servicer shall also be entitled to additional servicing
compensation in the form of: (i) interest or other income earned on deposits in
the REO Account, if established, in accordance with Section 3.06(b) (but only to
the extent of the Net Investment Earnings, if any, with respect to the REO
Account for each Collection Period); and (ii) to the extent not required to be
paid to any Mortgagor under applicable law, any interest or other income earned
on deposits in the Servicing Accounts maintained by the Special Servicer. The
Special Servicer shall be required to pay out of its own funds all general and
administrative expenses incurred by it in connection with its servicing
activities hereunder, and the Special Servicer shall not be entitled to
reimbursement therefor except as expressly provided in Section 3.05(a) if and to
the extent such expenses are not payable directly out of the Certificate Account
or the REO Account.

            Section 3.12 Property Inspections; Collection of Financial
Statements; Delivery of Certain Reports.

            (a) (i) The Special Servicer shall perform or cause to be performed
a physical inspection of a Mortgaged Property as soon as practicable after a
related Mortgage Loan becomes a Specially Serviced Mortgage Loan and (ii) the
Master Servicer (in the case of non-Specially Serviced Mortgage Loans other than
the Non-Serviced Mortgage Loans) or the Special Servicer (in the case of
Specially Serviced Mortgage Loans) shall perform or cause to be performed a
physical inspection of a Mortgaged Property as soon as the related Debt Service
Coverage Ratio set forth in the CMSA Comparative Financial Status Report of a
Mortgage Loan is below 1.0x; provided that, with respect to inspections prepared
by the Special Servicer, such expense shall be reimbursable first out of Penalty
Interest and late payment charges otherwise payable to the Special Servicer and
received in the Collection Period during which such inspection related expenses
were incurred, then as an Additional Trust Fund Expense (except to the extent
that such Additional Trust Fund Expense is payable out of the proceeds of any
Companion Loan pursuant to the related Intercreditor Agreement and this
Agreement). Each of the Master Servicer for each Mortgage Loan (other than a
Specially Serviced Mortgage Loan or REO Loan) and the Special Servicer for each
Specially Serviced Mortgage Loan and REO Loan shall (and, in the case of the
Master Servicer, at its expense) perform or cause to be performed an inspection
of all the Mortgaged Properties at least once per calendar year (or, in the case
of each Mortgaged Property securing a Mortgage Loan (other than a Specially
Serviced Mortgage Loan) with a then current principal balance (or allocated loan
amount) of less than $2,000,000 at the time of such inspection, every other
calendar year) beginning in 2006; provided, however, the Master Servicer shall
not be required to inspect any Mortgaged Property that has been inspected by the
Special Servicer during the immediately preceding six months. The Special
Servicer and the Master Servicer shall each prepare (and, in the case of the
Special Servicer, shall deliver to the Master Servicer) a written report of each
such inspection performed by it that sets forth in detail the condition of the
Mortgaged Property and that specifies the existence of: (i) any sale, transfer
or abandonment of the Mortgaged Property of which it is aware, (ii) any change
in the condition or value of the Mortgaged Property that it, in its reasonable
judgment, considers material, or (iii) any visible waste committed on the
Mortgaged Property. The Master Servicer shall deliver such reports to the
Trustee within 45 days of the related inspection and the Trustee shall, subject
to Section 3.15, make copies of all such inspection reports available for review
by Certificateholders and Certificate Owners during normal business hours at the
offices of the Trustee at all times after the Trustee's receipt thereof. Upon
written request and at the expense of the requesting party, the Trustee shall
deliver copies of any such inspection reports to Certificateholders and
Certificate Owners. The Special Servicer shall have the right to inspect or
cause to be inspected (at its own expense) every calendar year any Mortgaged
Property related to a loan that is not a Specially Serviced Mortgage Loan;
provided that the Special Servicer obtains the approval of the Master Servicer
prior to such inspection, and provides a copy of such inspection to the Master
Servicer; provided, further, that the Master Servicer and the Special Servicer
shall not both inspect a Mortgaged Property that is not securing a Specially
Serviced Mortgage Loan in the same calendar year. If the Special Servicer
performs such inspection, such inspection shall satisfy the Master Servicer's
inspection obligations pursuant to this paragraph (a).

            With respect to site inspection information, the Master Servicer
shall make such inquiry of any Mortgagor under any related Mortgage Loan as the
Special Servicer may reasonably request.

            If the Special Servicer initiates a servicing transfer under clause
(b) or (c) of the definition of "Specially Serviced Mortgage Loan," the Special
Servicer shall give written notice thereof to the Master Servicer, the
Controlling Class Representative and the Trustee in order to effectuate such
transfer.

            (b) Not later than 2:00 p.m. (New York City time) on the second
Business Day prior to each Determination Date, the Special Servicer shall
deliver or cause to be delivered to the Master Servicer the following reports
with respect to the Specially Serviced Mortgage Loans and any REO Properties

month: (i) a CMSA Property File; (ii) a CMSA Comparative Financial Status Report
and (iii) CMSA Financial File. Not later than 5:00 p.m. (New York City time) on
the first Business Day following each Determination Date, the Special Servicer
shall deliver or cause to be delivered to the Master Servicer the following
reports with respect to the Mortgage Loans (and, if applicable, the related REO
Properties) (or, as to clause (v) below, only with respect to Specially Serviced
Mortgage Loans) providing the required information as of such Determination
Date: (i) a CMSA Historical Liquidation Report; (ii) a CMSA Historical Loan
Modification and Corrected Mortgage Loan Report; (iii) a CMSA REO Status Report,
(iv) a CMSA Advance Recovery Report and (v) a CMSA Delinquent Loan Status
Report.

            (c) Not later than 4:00 p.m. (New York City time) on the third
Business Day after each Determination Date, the Master Servicer shall deliver or
cause to be delivered to the Trustee (in electronic format acceptable to the
Master Servicer and the Trustee) (A) the most recent CMSA Historical Loan
Modification and Corrected Mortgage Loan Report, CMSA Historical Liquidation
Report and CMSA REO Status Report received from the Special Servicer pursuant to
Section 3.12(b); (B) a CMSA Property File, a CMSA Comparative Financial Status
Report and a CMSA Financial File, each with the required information as of the
end of the preceding calendar month (in each case combining the reports prepared
by the Special Servicer and the Master Servicer); (C) a CMSA Loan Level
Reserve/LOC Report and CMSA Delinquent Loan Status Report, each with the
required information as of such Determination Date (in each case combining the
reports prepared by the Special Servicer and the Master Servicer); (D) a CMSA
Servicer Watchlist Report with the required information as of such Determination
Date; and (E) a CMSA Advance Recovery Report, with the required information as
of such Determination Date.

            (d) The Special Servicer will deliver to the Master Servicer the
reports set forth in Section 3.12(b) and this Section 3.12(d) and the Master
Servicer shall deliver to the Trustee the reports set forth in this Section 3.12
in an electronic format reasonably acceptable to the Special Servicer and the
Master Servicer with respect to the reports set forth in Section 3.12(b) and
this Section 3.12(d) and the Master Servicer and the Trustee with respect to the
reports set forth in Section 3.12(c). The Master Servicer may, absent manifest
error, conclusively rely on the reports to be provided by the Special Servicer
pursuant to Section 3.12(b) and this Section 3.12(d) and the 2005-C19 Master
Servicer, the LB-UBS 2005-C3 Master Servicer and the MSCI 2005-HQ6 Master
Servicer to the extent required to be provided pursuant to the 2005-C19 Pooling
and Servicing Agreement, the LB-UBS 2005-C3 Pooling and Servicing Agreement and
the MSCI 2005-HQ6 Pooling and Servicing Agreement, as the case may be. The
Trustee may, absent manifest error, conclusively rely on the CMSA Loan Periodic
Update File to be provided by the Master Servicer pursuant to Section 4.02(b).
In the case of information or reports to be furnished by the Master Servicer to
the Trustee pursuant to this Section 3.12, to the extent that such information
is based on reports to be provided by the Special Servicer pursuant to Section
3.12(b) and this Section 3.12(d) and, to the extent that such reports are to be
prepared and delivered by the Special Servicer pursuant to Section 3.12(b) and
this Section 3.12(d), the Master Servicer shall have no obligation to provide
such information or reports until it has received such information or reports
from the Special Servicer and the Master Servicer shall not be in default
hereunder due to a delay in providing the reports required by this Section 3.12
to the extent caused by the Special Servicer's failure to timely provide any
report required under Section 3.12(b) and this Section 3.12(d) of this
Agreement.

            The Special Servicer, in the case of any Specially Serviced Mortgage
Loan and REO Loan, and the Master Servicer, in the case of all other Mortgage
Loans, shall endeavor, consistent with the Servicing Standard, to obtain
quarterly and annual operating statements and rent rolls with respect to the
related Mortgage Loans and REO Properties, which efforts shall include (i) in
the case of Mortgage Loans other than the 2005-C19 Serviced Mortgage Loan, the
LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage
Loan, a letter sent to the related Mortgagor each quarter (followed up with
telephone calls) requesting such quarterly and annual operating statements and
rent rolls until they are received to the extent such action is consistent with
applicable law and the related Mortgage Loan documents, and (ii) with respect to
the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan
and the MSCI 2005-HQ6 Serviced Mortgage Loan, a letter sent to the 2005-C19
Master Servicer, the LB-UBS 2005-C3 Master Servicer and the MSCI 2005-HQ6 Master
Servicer, respectively, to provide such information to the extent required to be
delivered pursuant to the related Intercreditor Agreement.

            The Special Servicer shall promptly, following receipt, deliver
copies of the operating statements and rent rolls received or obtained by it to
the Master Servicer, and the Master Servicer shall deliver copies of the
operating statements and rent rolls received or obtained by it to the Rating
Agencies, the Trustee, the Special Servicer or the Controlling Class
Representative in each case (other than the Rating Agencies and the Controlling
Class Representative which shall be sent copies within 30 days following the
Master Servicer's receipt) upon request.

            Within 30 days after receipt by the Master Servicer or the Special
Servicer of any annual operating statements with respect to any Mortgaged
Property or REO Property, as applicable (other than, in each case, the Mortgaged
Property or REO Property related to the 2005-C19 Serviced Mortgage Loan, the
LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage
Loan), each of the Master Servicer and the Special Servicer shall prepare or
update and, with respect to any CMSA NOI Adjustment Worksheet prepared or
updated by the Special Servicer, forward to the Master Servicer, a CMSA NOI
Adjustment Worksheet for such Mortgaged Property or REO Property (with the
annual operating statements attached thereto as an exhibit).

            The Special Servicer with respect to each Specially Serviced
Mortgage Loan and REO Loan, and the Master Servicer with respect to each other
Mortgage Loan (other than the 2005-C19 Serviced Mortgage Loan, the LB-UBS
2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage Loan),
shall each prepare and maintain and forward to each other one CMSA Operating
Statement Analysis for each Mortgaged Property and REO Property, as applicable;
provided, however, that with respect to the AmericasMart Loan, the 101 Avenue of
the Americas Loan and the U-Haul Portfolio Loan, the Master Servicer shall
forward to each recipient of a CMSA Operating Statement Analysis hereunder a
copy of the CMSA Operating Statement Analysis received from the 2005-C19 Master
Servicer, the LB-UBS 2005-C3 Master Servicer or the MSCI 2005-HQ6 Master
Servicer related to the AmericasMart Loan, the 101 Avenue of the Americas Loan
and the U-Haul Portfolio Loan, respectively. The CMSA Operating Statement
Analysis for each Mortgaged Property and REO Property is to be updated by each
of the Master Servicer and the Special Servicer, as applicable, within thirty
days after its respective receipt of updated operating statements for such
Mortgaged Property or REO Property, as the case may be, but in no event less
frequently than annually by June 30th of each year. The Master Servicer and the
Special Servicer shall each use the "Normalized" column from the CMSA NOI
Adjustment Worksheet for any Mortgaged Property or REO Property, as the case may
be, to update the corresponding CMSA Operating Statement Analysis and shall use
any operating statements received with respect to any Mortgaged Property or REO
Property, as the case may be, to prepare the CMSA NOI Adjustment Worksheet for
such property. Copies of CMSA Operating Statement Analyses and CMSA NOI
Adjustment Worksheets are to be made available by the Master Servicer to the
Trustee, the Special Servicer or the Controlling Class Representative in each
case upon request.

            (e) With respect to the Serviced Pari Passu Mortgage Loans, the
Master Servicer and the Special Servicer, as applicable, will provide the
related Companion Holders with copies of any and all documents, certificates,
instruments, notices, reports, operating statements, rent rolls, correspondences
and other information required to be delivered pursuant to the terms of the
applicable Pari Passu Loan Intercreditor Agreement.

            Section 3.13 Annual Statement as to Compliance.

            Each of the Master Servicer and the Special Servicer shall deliver
to the Depositor, the Trustee, the Underwriters, the Controlling Class
Representative and the Rating Agencies, and, in the case of the Special
Servicer, to the Master Servicer, and, in the case of a Serviced Pari Passu
Companion Loan then included in a securitization, to the extent reasonably
requested by the holder (or its designee) of such Serviced Pari Passu Companion
Loan, to such holder during such times as such holder is subject to the
applicable reporting requirements of the Exchange Act, on or before March 15th
of each year (or April 30th of each year with respect to which the Depositor has
informed the Master Servicer that reports described in Section 8.17(a) are no
longer required to be filed), beginning March 15, 2006, an Officer's Certificate
stating, as to each signer thereof, that (i) a review of the activities of the
Master Servicer or the Special Servicer, as the case may be, during the
preceding calendar year and of its performance under this Agreement has been
made under such officer's supervision, (ii) to the best of such officer's
knowledge, based on such review, the Master Servicer or the Special Servicer, as
the case may be, has fulfilled all of its obligations under this Agreement in
all material respects throughout such year, or, if there has been a default in
the fulfillment of any such obligation, specifying each such default known to
such officer and the nature and status thereof and (iii) the Master Servicer or
the Special Servicer, as the case may be, has received no notice regarding
qualification, or challenging the status, of either of REMIC I or REMIC II as a
REMIC under the REMIC Provisions or of the Grantor Trusts as a "grantor trust"
for income tax purposes under the Grantor Trust Provisions from the Internal
Revenue Service or any other governmental agency or body or, if it has received
any such notice, specifying the details thereof. With respect to each year that
the reports described in Section 8.17(a) are filed, the Trustee shall review
such Officer's Certificate and inform the Depositor, the Master Servicer and the
Special Servicer of any material exceptions of which any Responsible Officer of
the Trustee has actual knowledge (it being understood that the Trustee is not
under any obligation to monitor the activities of the Master Servicer or Special
Servicer except to the extent required by this Section 3.13 and this Agreement)
prior to March 25th of the year received.

            Section 3.14 Reports by Independent Public Accountants.

            On or before March 15th of each year (or April 30th of each year
with respect to which the Depositor has informed the Master Servicer that
reports described in Section 8.17(a) are no longer required to be filed),
beginning March 15, 2006, each of the Master Servicer and the Special Servicer
at its expense shall cause a firm of Independent public accountants (which may
also render other services to the Master Servicer or the Special Servicer) that
is a member of the American Institute of Certified Public Accountants to furnish
a statement to the Trustee, the Underwriters, the Rating Agencies, the
Controlling Class Representative, the Depositor, and, in the case of the Special
Servicer, the Master Servicer, and, in the case of any Serviced Pari Passu
Companion Loan then included in a securitization, to the extent reasonably
requested by the holder (or its designee) of such Serviced Pari Passu Companion
Loan, to such holder during such times as such holder is subject to the
applicable reporting requirements of the Exchange Act, to the effect that such
firm has examined the servicing operations of the Master Servicer or the Special
Servicer, as the case may be, for the previous calendar year (except that the
first such report shall cover the period from the Closing Date through December
31, 2005) and that, on the basis of such examination, conducted substantially in
compliance with USAP, such firm confirms that the Master Servicer or the Special
Servicer, as the case may be, complied with the minimum servicing standards
identified in USAP, in all material respects, except for such significant
exceptions or errors in records that, in the opinion of such firm, the USAP
requires it to report. In rendering such statement, such firm may rely, as to
matters relating to direct servicing of mortgage loans by Sub-Servicers, upon
comparable statements for examinations conducted substantially in compliance
with the Uniform Single Audit Program for Mortgage Bankers (rendered within one
year of such statement) of independent public accountants with respect to the
related Sub-Servicer. With respect to each year that the reports described in
Section 8.17(a) are filed, prior to February 15th of each calendar year,
beginning February 15, 2006, the Trustee, shall notify the Depositor, the Master
Servicer and the Special Servicer of any material deficiencies in such
servicer's compliance with the terms of this Agreement during the preceding
calendar year of which a Responsible Officer of the Trustee has actual knowledge
(it being understood that the Trustee is not under any obligation to monitor the
activities of the Master Servicer or Special Servicer except to the extent
required by this Section 3.14 and this Agreement).

            Section 3.15 Access to Certain Information.

            (a) Upon ten days prior written notice, the Master Servicer (with
respect to the items in clauses (a), (b) (other than Distribution Date
Statements), (c), (d), (e), (f), (h) and (i) below, unless such item was not
delivered to the Master Servicer), the Special Servicer (with respect to the
items in clauses (c), (d), (g), (h) and (i) below) to the extent such items are
in its possession and the Trustee (with respect to the items in clauses (b) and
(i) below) and any other items, to the extent in its possession) shall make
available at their respective offices primarily responsible for administration

Office, except with respect to documents which constitute part of the Mortgage
Files, which will be maintained at its offices in Illinois), during normal
business hours, or send to the requesting party, such party having been
certified to the Trustee, the Master Servicer or the Special Servicer, as
applicable, in accordance with (a) and (b) in the following paragraph, as
appropriate, at the expense of such requesting party (unless otherwise provided
in this Agreement), for review by any Certificate Owner or Certificateholder or
any Person identified by a Certificate Owner or Certificateholder or its
designated agent to the Trustee, the Master Servicer or the Special Servicer, as
the case may be, as a prospective transferee of any Certificate or interest
therein or a Companion Loan or any interest therein (to the extent such
information is related to such Companion Loan or the related Mortgage Loan), the
Trustee, the Rating Agencies, the Underwriters and any applicable regulator or
potential purchaser specified thereby and the Depositor, originals or copies of
the following items: (a) this Agreement and any amendments thereto, (b) all
Distribution Date Statements delivered to holders of the relevant Class of
Certificates since the Closing Date and all reports, statements and analyses
delivered by the Master Servicer since the Closing Date pursuant to Section
3.12(c), (c) all Officer's Certificates delivered by the Master Servicer or the
Special Servicer since the Closing Date pursuant to Section 3.13, (d) all
accountants' reports delivered to the Master Servicer in respect of itself or
the Special Servicer since the Closing Date as described in Section 3.14, (e)
the most recent property inspection report prepared by or on behalf of the
Master Servicer in respect of each Mortgaged Property and any Environmental
Assessments prepared pursuant to Section 3.09, (f) the most recent Mortgaged
Property annual operating statements and rent roll, if any, collected by or on
behalf of the Master Servicer, (g) any and all modifications, waivers and
amendments of the terms of a Mortgage Loan entered into by the Special Servicer
and the Asset Status Report prepared pursuant to Section 3.21(d), (h) the
Servicing File relating to each Mortgage Loan and (i) any and all Officer's
Certificates and other evidence delivered by the Master Servicer or the Special
Servicer, as the case may be, to support its determination that any Advance was,
or if made, would be, a Nonrecoverable Advance pursuant to Sections 3.03(e) or
4.03(c), including appraisals affixed thereto and any Required Appraisal
prepared pursuant to Section 3.09(a). Copies of any and all of the foregoing
items will be available from the Master Servicer, the Special Servicer or the
Trustee, as the case may be, upon request and shall be provided to any of the
Rating Agencies at no cost pursuant to their reasonable requests.

            In connection with providing access to or copies of the items
described in the preceding paragraph pursuant to this Section 3.15, or with
respect to the Controlling Class Representative, in connection with providing
access to or copies of any items in accordance with this Agreement, the Trustee,
the Master Servicer or the Special Servicer, as applicable, shall require: (a)
in the case of Certificate Owners and the Controlling Class Representative, a
confirmation (which in the case of the Controlling Class Representative may be a
standing confirmation) executed by the requesting Person substantially in the
form of Exhibit K-1 hereto (or such other form as may be reasonably acceptable
to the Trustee, the Master Servicer or the Special Servicer, as applicable)
generally to the effect that such Person is a beneficial holder of Book-Entry
Certificates, or a representative of a beneficial holder of Book-Entry
Certificates, and, subject to the last sentence of this paragraph, will keep
such information confidential (except that such Certificate Owner and the
Controlling Class Representative may provide such information to any other
Person that holds or is contemplating the purchase of any Certificate or
interest therein; provided that such other Person confirms in writing such
ownership interest or prospective ownership interest and agrees to keep such
information confidential); and (b) in the case of a prospective purchaser of a
Certificate or an interest therein, confirmation executed by the requesting
Person substantially in the form of Exhibit K-2 hereto (or such other form as
may be reasonably acceptable to the Trustee, the Master Servicer or the Special
Servicer, as applicable) generally to the effect that such Person is a
prospective purchaser of a Certificate or an interest therein, is requesting the
information for use in evaluating a possible investment in Certificates and,
subject to the last sentence of this paragraph, will otherwise keep such
information confidential. The Holders of the Certificates, by their acceptance
thereof, and the Controlling Class Representative, by its acceptance of its
appointment, will be deemed to have agreed, subject to the last sentence of this
paragraph, to keep such information confidential (except that any Holder may
provide such information obtained by it to any other Person that holds or is
contemplating the purchase of any Certificate or interest therein; provided that
such other Person confirms in writing such ownership interest or prospective
ownership interest and agrees to keep such information confidential) and agrees
not to use such information in any manner that would violate federal, state or
local securities laws. Notwithstanding the foregoing, no Certificateholder,
Certificate Owner or prospective Certificateholder or Certificate Owner shall be
obligated to keep confidential any information received from the Trustee, the
Master Servicer or the Special Servicer, as applicable, pursuant to this Section
3.15 that has previously been made available via the Trustee's, the Master
Servicer's or Special Servicer's Internet Website without restriction as to
access as permitted pursuant to the terms of this Agreement, as applicable, or
has previously been filed with the Commission, and the Trustee, the Master
Servicer or the Special Servicer, as applicable, shall not require either of the
certifications contemplated by the second preceding sentence in connection with
providing any information pursuant to this Section 3.15 that has previously been
made available via the Trustee's, the Master Servicer's or Special Servicer's
Internet Website without restriction as to access in compliance with the terms
of this Agreement, as applicable, or has previously been filed with the
Commission.

            Each of the Master Servicer and the Special Servicer shall afford to
the Trustee, the Rating Agencies and the Depositor, and to the OTS, the FDIC,
the Federal Reserve Board and any other banking or insurance regulatory
authority that may exercise authority over any Certificateholder or a Companion
Loan or any interest therein (to the extent such information is related to such
Companion Loan or the related Mortgage Loan), access to any records regarding
the Mortgage Loans and the servicing thereof within its control, except to the
extent it is prohibited from doing so by applicable law or contract or to the
extent such information is subject to a privilege under applicable law to be
asserted on behalf of the Certificateholders or the Companion Holders. Such
access shall be afforded only upon reasonable prior written request and during
normal business hours at the offices of the Master Servicer or the Special
Servicer, as the case may be, designated by it.

            The Trustee, the Master Servicer, the Special Servicer and the
Underwriters may require payment from the Certificateholder or Certificate Owner
or holder of a Companion Loan, as applicable, of a sum sufficient to cover the
reasonable costs and expenses of providing any such information or access
pursuant to this Section 3.15 to, or at the request of, the Certificateholders
or Certificate Owners or prospective transferees or holder of a Companion Loan,
as applicable, including, without limitation, copy charges and, in the case of
Certificateholders or Certificate Owners or holder of a Companion Loan, if
applicable, requiring on site review in excess of three Business Days,
reasonable fees for employee time and for space.

            (b) The Trustee shall, and the Master Servicer may, but is not
required to, make available on or prior to the Distribution Date in each month
to any interested party (i) the Distribution Date Statement via their respective
Internet Websites, (ii) as a convenience for interested parties, the Prospectus
Supplement, the Prospectus and this Agreement on their respective Internet
Websites and (iii) any other items at the request of the Depositor via their
respective Internet Websites. In addition, the Trustee shall make available each
month, on each Distribution Date, the Unrestricted Servicer Reports, the CMSA
Loan Periodic Update File, the CMSA Loan Setup File, the CMSA Bond File and the
CMSA Collateral Summary File to any interested party on its Internet Website.
The Trustee shall, upon written request, make available each month, on each
Distribution Date, (i) the Restricted Servicer Reports, and (ii) the CMSA
Property File and the CMSA Financial File to any Privileged Person and to any
other Person upon the direction of the Depositor.

            The Master Servicer may, but is not required to, make available each
month via its Internet Website (i) to any interested party, the Unrestricted
Servicer Reports, the CMSA Loan Setup File and the CMSA Loan Periodic Update
File, and (ii) to any Privileged Person, with the use of a password provided by
the Master Servicer, the Restricted Servicer Reports, the CMSA Financial File
and the CMSA Property File. Any Restricted Servicer Report or Unrestricted
Servicer Report that is not available on the Master Servicer's Internet Website
as described in the immediately preceding sentence by 5:00 p.m. (New York City
time) on the related Distribution Date shall be provided (in electronic format,
or if electronic mail is unavailable, by facsimile) by the Master Servicer, upon
request, to any Person otherwise entitled to access such report on the Master
Servicer's Internet Website.

            In connection with providing access to the Trustee's Internet
Website or the Master Servicer's Internet Website, the Trustee or the Master
Servicer, as applicable, may require registration and the acceptance of a
disclaimer.

            If three or more Holders or the Controlling Class Representative
(hereinafter referred to as "Applicants" with a single Person which (together
with its Affiliates) is the Holder of more than one Class of Certificates being
viewed as a single Applicant for these purposes) apply in writing to Trustee,
and such application states that the Applicants' desire to communicate with
other Holders with respect to their rights under this Agreement or under the
Certificates and is accompanied by a copy of the communication which such
Applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, send, at the Applicants' expense,
the written communication proffered by the Applicants to all Certificateholders
at their addresses as they appear in the Certificate Register.

            (c) The Master Servicer and the Special Servicer shall not be
required to confirm, represent or warrant the accuracy or completeness of any
other Person's information or report included in any communication from the
Master Servicer or the Special Servicer under this Agreement. Neither the Master
Servicer nor the Trustee shall be liable for the dissemination of information in
accordance with this Section 3.15(c). The Trustee makes no representations or
warranties as to the accuracy or completeness of any report, document or other
information made available on the Trustee's Website and assumes no
responsibility therefor. In addition, the Trustee, the Master Servicer and the
Special Servicer may disclaim responsibility for any information distributed by
the Trustee, the Master Servicer or the Special Servicer, respectively, for
which it is not the original source.

            (d) Upon the request of the Controlling Class Representative made
not more frequently than once a month (which request may be a standing,
continuing request), or at such mutually acceptable time each month as the
Controlling Class Representative shall reasonably designate, each of the Master
Servicer and Special Servicer shall, without charge, make a knowledgeable
Servicing Officer available, at the option of the Controlling Class
Representative either by telephone or at the office of such Servicing Officer,
to answer questions from the Controlling Class Representative regarding the
performance and servicing of the Mortgage Loans and/or REO Properties for which
such Master Servicer or Special Servicer, as the case may be, is responsible.
The Master Servicer and the Special Servicer each shall condition such
disclosure upon the Controlling Class Representative entering into a reasonable
and customary confidentiality agreement reasonably acceptable to such servicer
and the Controlling Class Representative regarding such disclosure to it.
Neither the Master Servicer nor the Special Servicer shall be required to
provide any information or disclosures in violation of any applicable law, rule
or regulation.

            (e) With respect to any Companion Loan, the Companion Holders shall
receive and have access to any information described in this Section 3.15 which
such Companion Holder is entitled to pursuant to the related Intercreditor
Agreement.

            Section 3.16 Title to REO Property; REO Account.

            (a) If title to any REO Property is acquired, the deed or
certificate of sale shall be issued to the Trustee or its nominee on behalf of
the Certificateholders and, if applicable, the Companion Holder, as their
interests shall appear. The Special Servicer, on behalf of the Trust Fund, shall
sell any REO Property as soon as practicable in accordance with the Servicing
Standard, but prior to the end of the third year following the calendar year in
which REMIC I acquires ownership of such REO Property (or applicable portion
thereof) for purposes of Section 860G(a)(8) of the Code, unless the Special
Servicer either (i) applies for, more than sixty days prior to the end of such
third succeeding year, and is granted an extension of time (an "REO Extension")
by the Internal Revenue Service to sell such REO Property or (ii) obtains for
the Trustee an Opinion of Counsel, addressed to the Trustee, the Special
Servicer and the Master Servicer, to the effect that the holding by REMIC I of
such REO Property subsequent to the end of such third succeeding year will not
result in the imposition of taxes on "prohibited transactions" (as defined in
Section 860F of the Code) of either of REMIC I or REMIC II or cause either of
REMIC I or REMIC II to fail to qualify as a REMIC at any time that any
Certificates are outstanding. If the Special Servicer is granted the REO
Extension contemplated by clause (i) of the immediately preceding sentence or
obtains the Opinion of Counsel contemplated by clause (ii) of the immediately
preceding sentence, the Special Servicer shall sell such REO Property within
such extended period as is permitted by such REO Extension or such Opinion of
Counsel, as the case may be. Any expense incurred by the Special Servicer in
connection with its obtaining the REO Extension contemplated by clause (i) of
the second preceding sentence or its obtaining the Opinion of Counsel
contemplated by clause (ii) of the second preceding sentence, shall first be
payable from the related REO Account to the extent of available funds and then
be a Servicing Advance by the Master Servicer.

            (b) The Special Servicer shall segregate and hold all funds
collected and received in connection with any REO Property separate and apart
from its own funds and general assets. If an REO Acquisition shall occur, the
Special Servicer shall establish and maintain one or more accounts
(collectively, the "REO Account"), held on behalf of the Trustee in trust for
the benefit of the Certificateholders and, if applicable, the Companion Holder,
as their interests shall appear, for the retention of revenues and other
proceeds derived from each REO Property. The REO Account shall be an Eligible
Account. The Special Servicer shall deposit, or cause to be deposited, in the
REO Account, upon receipt, all REO Revenues, Insurance Proceeds and Liquidation
Proceeds (net of Liquidation Expenses) received in respect of an REO Property
within 2 Business Days of receipt. Funds in the REO Account may be invested in
Permitted Investments in accordance with Section 3.06. The Special Servicer
shall be entitled to make withdrawals from the REO Account to pay itself, as
additional servicing compensation in accordance with Section 3.11(d), interest
and investment income earned in respect of amounts held in the REO Account as
provided in Section 3.06(b) (but only to the extent of the Net Investment
Earnings with respect to the REO Account for any Collection Period). The Special
Servicer shall give written notice to the Trustee, and the Master Servicer of
the location of the REO Account when first established and of the new location
of the REO Account prior to any change thereof.

            (c) The Special Servicer shall withdraw from the REO Account funds
necessary for the proper operation, management, maintenance and disposition of
any REO Property, but only to the extent of amounts on deposit in the REO
Account relating to such REO Property (including any monthly reserve or escrow
amounts necessary to accumulate sufficient funds for taxes, insurance and
anticipated capital expenditures (the "Impound Reserve")). On the last day of
the related Collection Period, the Special Servicer shall withdraw from the REO
Account and deposit into the Certificate Account or deliver to the Master
Servicer or such other Person as may be directed by the Master Servicer (which
shall deposit such amounts into the Certificate Account) the aggregate of all
amounts received in respect of each REO Property during the most recently ended
Collection Period, net of any withdrawals made out of such amounts pursuant to
the preceding sentence; provided that, in addition to the Impound Reserve, the
Special Servicer may retain in the REO Account such portion of proceeds and
collections as may be necessary to maintain a reserve of sufficient funds for
the proper operation, management and maintenance of the related REO Property
(including, without limitation, the creation of a reasonable reserve for
repairs, replacements and other related expenses).

            (d) The Special Servicer shall keep and maintain separate records,
on a property-by-property basis, for the purpose of accounting for all deposits
to, and withdrawals from, the REO Account pursuant to Section 3.16(b) or (c).
The Special Servicer shall provide the Master Servicer any information with
respect to the REO Account as is reasonably requested by the Master Servicer.

            Section 3.17 Management of REO Property.

            (a) Prior to the acquisition of title to a Mortgaged Property, the
Special Servicer shall review the operation of such Mortgaged Property and
determine the nature of the income that would be derived from such property if
it were acquired by the Trust Fund. If the Special Servicer determines from such
review in compliance with the Servicing Standard that in its good faith and
reasonable judgment:

                  (i) None of the income from Directly Operating such REO
            Property would be subject to tax as "net income from foreclosure
            property" within the meaning of the REMIC Provisions (such tax
            referred to herein as an "REO Tax"), and the Special Servicer does
            not engage in any of the activities described in the definition of
            "Directly Operate" that would cause the REO Property to cease to
            qualify as "foreclosure property" within the meaning of Section
            860G(a)(8) of the Code, then such Mortgaged Property may be Directly
            Operated by the Special Servicer as REO Property;

                  (ii) Directly Operating such Mortgaged Property as an REO
            Property could result in income from such property that would be
            subject to an REO Tax, but that a lease of such property to another
            party to operate such property, or the performance of some services
            by an Independent Contractor with respect to such property, or
            another method of operating such property would not result in income
            subject to an REO Tax, then the Special Servicer may (provided that
            in the good faith and reasonable judgment of the Special Servicer,
            such alternative is commercially feasible and would result in a
            greater net recovery on a present value basis than earning income
            subject to an REO Tax) acquire such Mortgaged Property as REO
            Property and so lease or manage such REO Property; or

                  (iii) It is reasonable to believe that Directly Operating such
            property as REO Property could result in income subject to an REO
            Tax and that such method of operation is commercially feasible and
            would result in a greater net recovery on a present value basis than
            leasing or other method of operating the REO Property that would not
            incur an REO Tax, the Special Servicer shall deliver to the REMIC
            Administrator, in writing, a proposed plan (the "Proposed Plan") to
            manage such property as REO Property. Such plan shall include
            potential sources of income, and to the extent commercially
            feasible, estimates of the amount of income from each such source.
            Within a reasonable period of time after receipt of such plan, the
            REMIC Administrator shall consult with the Special Servicer and
            shall advise the Special Servicer of the REMIC Administrator's
            federal income tax reporting position with respect to the various
            sources of income that the Trust Fund would derive under the
            Proposed Plan. In addition, the REMIC Administrator shall (to the
            extent reasonably possible) advise the Special Servicer of the
            estimated amount of taxes that the Trust Fund would be required to
            pay with respect to each such source of income. After receiving the
            information described in the two preceding sentences from the REMIC
            Administrator, the Special Servicer shall either (A) implement the
            Proposed Plan (after acquiring the respective Mortgaged Property as
            REO Property) or (B) manage such property in a manner that would not
            result in the imposition of an REO Tax on the income derived from
            such property. All of the REMIC Administrator's expenses (including
            any fees and expenses of counsel or other experts reasonably
            retained by it) incurred pursuant to this Section shall be
            reimbursed to it from the Trust Fund in accordance with Section
            10.01(e).

            The Special Servicer's decision as to how each REO Property shall be
managed shall be based on the Servicing Standard and in any case on the good
faith and reasonable judgment of the Special Servicer as to which means would be
in the best interest of the Certificateholders (or, if the REO Property was
formerly a Mortgaged Property securing a Co-Lender Loan, the Certificateholders
and the related Companion Holder (as a collective whole in accordance with the
Servicing Standard, taking into account the subordinate nature of the Companion
Loan, if applicable)) by maximizing (to the extent commercially feasible and
consistent with Section 3.17(b)) the net after-tax REO Revenues received by the
Trust Fund with respect to such property and, to the extent consistent with the
foregoing, in the same manner as would prudent mortgage loan servicers operating
acquired mortgaged property comparable to the respective Mortgaged Property.
Both the Special Servicer and the REMIC Administrator may, at the expense of the
Trust Fund payable pursuant to Section 3.05(a)(xiv), consult with counsel.

            (b) If title to any REO Property is acquired, the Special Servicer
shall manage, conserve and protect such REO Property for the benefit of the
Certificateholders (or, if the REO Property was formerly a Mortgaged Property
securing a Co-Lender Loan, the Certificateholders and the related Companion
Holder (as a collective whole in accordance with the Servicing Standard, taking
into account the subordinate nature of the Companion Loan, if applicable))
solely for the purpose of its prompt disposition and sale in a manner that does
not and will not cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code or either result
in the receipt by REMIC I of any "income from non-permitted assets" within the
meaning of Section 860F(a)(2)(B) of the Code or result in an Adverse REMIC
Event. Subject to the foregoing, however, the Special Servicer shall have full
power and authority to do any and all things in connection therewith as are
consistent with the Servicing Standard and, consistent therewith, shall withdraw
from the REO Account, to the extent of amounts on deposit therein with respect
to any REO Property, funds necessary for the proper management, maintenance and
disposition of such REO Property, including without limitation:

                  (i) all insurance premiums due and payable in respect of such
            REO Property;

                  (ii) all real estate taxes and assessments in respect of such
            REO Property that may result in the imposition of a lien thereon;

                  (iii) any ground rents in respect of such REO Property; and

                  (iv) all costs and expenses necessary to maintain, lease,
            sell, protect, manage and restore such REO Property.

            To the extent that amounts on deposit in the REO Account in respect
of any REO Property are insufficient for the purposes set forth in the preceding
sentence with respect to such REO Property, the Master Servicer, subject to the
second paragraph of Section 3.03(c), shall make Servicing Advances in such
amounts as are necessary for such purposes unless (as evidenced by an Officer's
Certificate delivered to the Trustee and the Fiscal Agent) the Master Servicer
would not make such advances if the Master Servicer owned such REO Property or
the Master Servicer determines, in accordance with the Servicing Standard, that
such payment would be a Nonrecoverable Advance; provided, however, that the
Master Servicer may make any such Servicing Advance without regard to
recoverability if it is a necessary fee or expense incurred in connection with
the defense or prosecution of legal proceedings.

            (c) Unless Section 3.17(a)(i) applies, the Special Servicer shall
contract with any Independent Contractor (if required by the REMIC Provisions
for the REO Property to remain classified as "foreclosure property" within the
meaning of Section 860G(a)(8) of the Code) for the operation and management of
any REO Property; provided that:

                  (i) the terms and conditions of any such contract may not be
            inconsistent herewith and shall reflect an agreement reached at
            arm's length;

                  (ii) the fees of such Independent Contractor (which shall be
            expenses of the Trust Fund) shall be reasonable and customary in
            consideration of the nature and locality of the REO Property;

                  (iii) except as permitted under Section 3.17(a), any such
            contract shall require, or shall be administered to require, that
            the Independent Contractor, in a timely manner, pay all costs and
            expenses incurred in connection with the operation and management of
            such REO Property, including, without limitation, those listed in
            Section 3.17(b) above, and remit all related revenues collected (net
            of its fees and such costs and expenses) to the Special Servicer
            upon receipt;

                  (iv) none of the provisions of this Section 3.17(d) relating
            to any such contract or to actions taken through any such
            Independent Contractor shall be deemed to relieve the Special
            Servicer of any of its duties and obligations hereunder with respect
            to the operation and management of any such REO Property; and

                  (v) the Special Servicer shall be obligated with respect
            thereto to the same extent as if it alone were performing all duties
            and obligations in connection with the operation and management of
            such REO Property.

            The Special Servicer shall be entitled to enter into any agreement
with any Independent Contractor performing services for it related to its duties
and obligations hereunder for indemnification of the Special Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. No agreement entered into pursuant to this
Section 3.17(d) shall be deemed a Sub-Servicing Agreement for purposes of
Section 3.22.

            (d) Without limiting the generality of the foregoing, the Special
Servicer shall not:

                  (i) permit the Trust Fund to enter into, renew or extend any
            New Lease with respect to any REO Property, if the New Lease by its
            terms will give rise to any income that does not constitute Rents
            from Real Property;

                  (ii) permit any amount to be received or accrued under any New
            Lease other than amounts that will constitute Rents from Real
            Property;

                  (iii) authorize or permit any construction on any REO
            Property, other than the repair or maintenance thereof or the
            completion of a building or other improvement thereon, but only to
            the extent provided in Section 856(e)(4)(B) of the Code; or

                  (iv) except as otherwise provided for in Section 3.17(a)(i)
            and (a)(ii) above, Directly Operate, or allow any other Person,
            other than an Independent Contractor, to Directly Operate, any REO
            Property on any date more than 90 days after its Acquisition Date;

unless, in any such case, the Special Servicer has obtained an Opinion of
Counsel (the cost of which shall be paid by the Master Servicer as a Servicing
Advance unless nonrecoverable, in which case it shall be paid by the Master
Servicer as an Additional Trust Fund Expense from amounts on deposit in the
Certificate Account) to the effect that such action will not cause such REO
Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code at any time that it is held by the Trust Fund, in
which case the Special Servicer may take such actions as are specified in such
Opinion of Counsel. Except as limited above in this Section 3.17 and by this
Section 3.17(d), the Special Servicer shall be permitted to cause the Trust Fund
to earn "net income from foreclosure property", subject to the Servicing
Standard.

            Section 3.18 Resolution of Defaulted Mortgage Loans and REO
Properties.

            (a) The Master Servicer, the Special Servicer or the Trustee may
sell or purchase, or permit the sale or purchase of, a Mortgage Loan or an REO
Property only on the terms and subject to the conditions set forth in this
Section 3.18 or as otherwise expressly provided in or contemplated by Sections
2.03 and 9.01.

            (b) Within 60 days after a Mortgage Loan becomes a Defaulted
Mortgage Loan, the Special Servicer shall determine the fair value of the
Mortgage Loan in accordance with the Servicing Standard; provided, however, that
such determination shall be made without taking into account any effect the
restrictions on the sale of such Mortgage Loan contained herein may have on the
value of such Defaulted Mortgage Loan; provided, further, that, the Special
Servicer shall use reasonable efforts promptly to obtain an Appraisal with
respect to the related Mortgaged Property unless it has an Appraisal that is
less than 12 months old and has no actual knowledge of, or notice of, any event
which in the Special Servicer's judgment would materially affect the validity of
such Appraisal. The Special Servicer shall make its fair value determination as
soon as reasonably practicable (but in any event within thirty (30) days) after
its receipt of such new Appraisal, if applicable. The Special Servicer is
permitted to change, from time to time, its determination of the fair value of a
Defaulted Mortgage Loan based upon changed circumstances, new information or
otherwise, in accordance with the Servicing Standard; provided, however, the
Special Servicer shall update its determination of the fair value at least once
every 90 days. The Special Servicer shall notify the Trustee, the Master
Servicer, each Rating Agency and the Majority Subordinate Certificateholder
promptly upon its fair value determination and any adjustment thereto. In
determining the fair value of any Defaulted Mortgage Loan, the Special Servicer
shall take into account, among other factors, the period and amount of the
delinquency on such Mortgage Loan, the occupancy level and physical condition of
the related Mortgaged Property, the state of the local economy in the area where
the Mortgaged Property is located, and the time and expense associated with a
purchaser's foreclosing on the related Mortgaged Property. In addition, the
Special Servicer shall refer to all other relevant information obtained by it or
otherwise contained in the Mortgage Loan File; provided that the Special
Servicer shall take account of any change in circumstances regarding the related
Mortgaged Property known to the Special Servicer that has occurred subsequent
to, and that would, in the Special Servicer's reasonable judgment, materially
affect the value of the related Mortgaged Property reflected in the most recent
related Appraisal. Furthermore, the Special Servicer shall consider all
available objective third-party information obtained from generally available
sources, as well as information obtained from vendors providing real estate
services to the Special Servicer, concerning the market for distressed real
estate loans and the real estate market for the subject property type in the
area where the related Mortgaged Property is located. The Special Servicer may
conclusively rely on the opinion and reports of Independent third parties in
making such determination.

            (c) Subject to the terms set forth in Section 2.03, in the event a
Mortgage Loan becomes a Defaulted Mortgage Loan, each of the Majority
Subordinate Certificateholder and the Special Servicer shall have an assignable
option (a "Purchase Option") to purchase such Defaulted Mortgage Loan from the
Trust Fund at a price (the "Option Price") equal to (i) the Purchase Price, if
the Special Servicer has not yet determined the fair value of the Defaulted
Mortgage Loan, or (ii) the fair value of the Defaulted Mortgage Loan as
determined by the Special Servicer in the manner described in Section 3.18(b)
and in accordance with the Servicing Standard, if the Special Servicer has made
such fair value determination. Any holder of a Purchase Option may sell,
transfer, assign or otherwise convey its Purchase Option with respect to any
Defaulted Mortgage Loan to any party other than the related Mortgagor or an
Affiliate of the related Mortgagor under the Mortgage Loan at any time after the
related Mortgage Loan becomes a Defaulted Mortgage Loan. The transferor of any
Purchase Option shall notify the Trustee and the Master Servicer of such
transfer and such notice shall include the transferee's name, address, telephone
number, facsimile number and appropriate contact person(s) and shall be
acknowledged in writing by the transferee. Notwithstanding the foregoing, and
subject to Section 3.18(d) of this Agreement, the Majority Subordinate
Certificateholder shall have the right to exercise its Purchase Option prior to
any exercise of the Purchase Option by any other holder of a Purchase Option;
provided, however, if the Purchase Option is not exercised by the Majority
Subordinate Certificateholder or any assignee thereof within 60 days of a
Mortgage Loan becoming a Defaulted Mortgage Loan, then the Special Servicer
shall have the right to exercise its Purchase Option prior to any exercise by
the Majority Subordinate Certificateholder and the Special Servicer or its
assignee may exercise such Purchase Option at any time during the fifteen day
period immediately following the expiration of such 60-day period. Following the
expiration of such fifteen day period, the Majority Subordinate
Certificateholder shall again have the right to exercise its Purchase Option
prior to any exercise of the Purchase Option by the Special Servicer. If not
exercised earlier, the Purchase Option with respect to any Defaulted Mortgage
Loan will automatically terminate (i) once the related Defaulted Mortgage Loan
is no longer a Defaulted Mortgage Loan; provided, however, that, if such
Mortgage Loan subsequently becomes a Defaulted Mortgage Loan, the related
Purchase Option shall again be exercisable, (ii) upon the acquisition, by or on
behalf of the Trust Fund, of title to the related Mortgaged Property through
foreclosure or deed in lieu of foreclosure or (iii) the modification or pay-off,
in full or at a discount, of such Defaulted Mortgage Loan in connection with a
workout.

            (d) Notwithstanding the provisions of Section 3.18(c), Section
3.18(g) or Section 3.18(h), pursuant to the terms of the Intercreditor
Agreements, a Companion Holder will have the right to purchase the related
Co-Lender Loan or related REO Property in certain circumstances. Such right of
the related Companion Holder shall have priority over any provision described in
Section 3.18(c), Section 3.18(g) or Section 3.18(h). If the Co-Lender Loan or
REO Property is purchased by the related Companion Holder, repurchased by the
applicable Mortgage Loan Seller or otherwise ceases to be subject to this
Agreement, the related Companion Loan will no longer be subject to this
Agreement. Neither the Trustee nor the Trust Fund shall acquire a Companion
Loan; provided, however, the Master Servicer or an affiliate may own or acquire
the Companion Loans. With respect to each Loan Pair, the related Companion
Holder shall be entitled to exercise any cure rights given to it under the
related Intercreditor Agreement, in each case subject to any conditions or
restrictions described in or incorporated by reference into such sections.

            (e) Upon receipt of notice from the Special Servicer indicating that
a Mortgage Loan has become a Defaulted Mortgage Loan, the holder (whether the
original grantee of such option or any subsequent transferee) of the Purchase
Option may exercise the Purchase Option by providing the Master Servicer and the
Trustee written notice thereof (the "Purchase Option Notice"), in the form of
Exhibit N, which notice shall identify the Person that, on its own or through an
Affiliate, will acquire the related Mortgage Loan upon closing and shall specify
a cash exercise price at least equal to the Option Price. The Purchase Option
Notice shall be delivered in the manner specified in Section 11.05. The exercise
of any Purchase Option pursuant to this clause (e) shall be irrevocable.

            (f) If the Special Servicer or the Majority Subordinate
Certificateholder, or any of their respective Affiliates, is identified in the
Purchase Option Notice as the Person expected to acquire the related Mortgage
Loan, the Trustee shall determine as soon as reasonably practicable (and, in any
event, within thirty (30) days) after the Trustee has received the written
notice, whether the Option Price represents fair value for the Defaulted
Mortgage Loan; provided that, if the Special Servicer is then in the process of
obtaining a new Appraisal with respect to the related Mortgaged Property, then
the Trustee shall, in accordance with its good faith and reasonable judgment,
make its fair value determination with respect to such Mortgage Loan as soon as
reasonably practicable (but in any event within thirty (30) days) after the
Trustee's receipt of such new Appraisal. The Trustee may rely on the opinion and
reports of independent third parties in making such determination; provided that
the Trustee may rely on the most current Appraisal obtained for the related
Mortgaged Property pursuant to this Agreement. In determining the fair value of
any Defaulted Mortgage Loan, the Trustee shall take into account, and any
Independent third party shall be instructed to take into account, among other
factors, the period and amount of the delinquency on such Mortgage Loan, the
occupancy level and physical condition of the related Mortgaged Property, the
state of the local economy in the area where the Mortgaged Property is located,
and the time and expense associated with a purchaser's foreclosing on the
related Mortgaged Property. In addition, the Trustee shall refer, and any
Independent third party shall be instructed to refer, to all relevant
information delivered to it by the Special Servicer or otherwise contained in
the Mortgage Loan File. Furthermore, the Trustee shall consider, and any
Independent third party shall be instructed to consider, all available objective
third-party information obtained from generally available sources, concerning
the market for distressed real estate loans and the real estate market for the
subject property type in the area where the related Mortgaged Property is
located. The reasonable costs of all appraisals, inspection reports and broker
opinions of value, reasonably incurred by the Trustee or any such third party
pursuant to this subsection shall be advanced by the Master Servicer and shall
constitute, and be reimbursable as, Servicing Advances (or if such Advance is
deemed to be a Nonrecoverable Advance such costs shall be reimbursable as
Additional Trust Fund Expenses from the Certificate Account pursuant to Section
3.05(a)). The other parties to this Agreement shall cooperate with all
reasonable requests for information.

            (g) Unless and until the Purchase Option with respect to a Defaulted
Mortgage Loan is exercised, the Special Servicer shall pursue such other
resolution strategies available hereunder with respect to such Defaulted
Mortgage Loan, including, without limitation, workout and foreclosure, as the
Special Servicer may deem appropriate consistent with the Servicing Standard;
provided, however, the Special Servicer will not be permitted to sell the
Defaulted Mortgage Loan other than in connection with the exercise of the
related Purchase Option.

            (h) In the event that title to any REO Property is acquired by the
Trust Fund in respect of any Defaulted Mortgage Loan, the deed or certificate of
sale shall be issued to the Trust, the Trustee or to its nominees. The Special
Servicer, after notice to the Controlling Class Representative, shall use its
reasonable best efforts to sell any such REO Property as soon as practicable in
accordance with Section 3.16(a). If the Special Servicer on behalf of the
Trustee has not received an REO Extension or an Opinion of Counsel described in
Section 3.16(a) and the Special Servicer is not able to sell such REO Property
within the period specified above, or if an REO Extension has been granted and
the Special Servicer is unable to sell such REO Property within the extended
time period, the Special Servicer shall, after consultation with the Controlling
Class Representative, before the end of such period or extended period, as the
case may be, auction the REO Property to the highest bidder (which may be the
Special Servicer) in accordance with the Servicing Standard. The Special
Servicer shall give the Controlling Class Representative, the Master Servicer
and the Trustee not less than five days' prior written notice of its intention
to sell any REO Property, and in respect of such sale, the Special Servicer
shall offer such REO Property in a commercially reasonable manner. Where any
Interested Person is among those bidding with respect to an REO Property, the
Special Servicer shall require that all bids be submitted in writing and be
accompanied by a refundable deposit of cash in an amount equal to 5% of the bid
amount. No Interested Person shall be permitted to purchase the REO Property at
a price less than the Purchase Price; and provided, further, that, if the
Special Servicer intends to bid on any REO Property, (i) the Special Servicer
shall notify the Trustee of such intent, (ii) the Trustee shall promptly obtain,
at the expense of the Trust, an Appraisal of such REO Property and (iii) the
Special Servicer shall not bid less than the greater of (a) the fair market
value set forth in such Appraisal or (b) the Purchase Price.

            (i) Subject to the REMIC Provisions, the Special Servicer shall act
on behalf of the Trust Fund in negotiating and taking any other action necessary
or appropriate in connection with the sale of any REO Property or the exercise
of a Purchase Option, including the collection of all amounts payable in
connection therewith. Notwithstanding anything to the contrary herein, neither
the Trustee, in its individual capacity, nor any of its Affiliates may bid for
or purchase any REO Property or purchase any Defaulted Mortgage Loan. Any sale
of a Defaulted Mortgage Loan (pursuant to a Purchase Option) or an REO Property
shall be without recourse to, or representation or warranty by, the Trustee, the
Depositor, the Special Servicer, the Master Servicer, any Mortgage Loan Seller
or the Trust Fund. Notwithstanding the foregoing, nothing herein shall limit the
liability of the Master Servicer, the Special Servicer or the Trustee to the
Trust Fund and the Certificateholders for failure to perform its duties in
accordance herewith. None of the Special Servicer, the Master Servicer, the
Depositor or the Trustee shall have any liability to the Trust Fund or any
Certificateholder with respect to the price at which a Defaulted Mortgage Loan
is sold if the sale is consummated in accordance with the terms of this
Agreement.

            (j) Upon exercise of a Purchase Option, the holder of such Purchase
Option shall be required to pay the purchase price specified in its Purchase
Option Notice to the Special Servicer within 10 Business Days of exercising its
Purchase Option. The proceeds of any sale of a Defaulted Mortgage Loan, after
deduction of the expenses of such sale incurred in connection therewith, shall
be remitted by the Special Servicer to the Master Servicer within one Business
Day of receipt for deposit into the Certificate Account. The Special Servicer
shall immediately notify the Trustee upon the holder of the effective Purchase
Option's failure to remit the purchase price specified in its Purchase Option
Notice pursuant to this Section 3.18(j). Thereafter, the Special Servicer shall
notify each holder of a Purchase Option of such failure and such holder of a
Purchase Option may then exercise its Purchase Option in accordance with this
Section 3.18.

            (k) Notwithstanding anything herein to the contrary, the Special
Servicer shall not take or refrain from taking any action pursuant to
instructions from the Controlling Class Representative that would cause it to
violate applicable law or any term or provision of this Agreement, including the
REMIC Provisions and the Servicing Standard.

            (l) The amount paid for a Defaulted Mortgage Loan or related REO
Property purchased under this Agreement shall be deposited into the Certificate
Account, or if applicable, applied in accordance with the related Intercreditor
Agreement (except that portion of any purchase price constituting Gain-on-Sale
Proceeds which shall be deposited in the Gain-on-Sale Reserve Account). Upon
receipt of an Officer's Certificate from the Master Servicer to the effect that
such deposit has been made, the Trustee shall execute and deliver such
instruments of transfer or assignment, in each case without recourse, as shall
be provided to it and are reasonably necessary to vest in the purchaser of such
Defaulted Mortgage Loan or related REO Property ownership of the Defaulted
Mortgage Loan or REO Property. The Custodian, upon receipt of a Request for
Release, shall release or cause to be released to the Master Servicer or Special
Servicer the related Mortgage File. In connection with any such purchase, the
Special Servicer shall deliver the related Servicing File to the purchaser of a
Defaulted Mortgage Loan or related REO Property.

            (m) Notwithstanding the foregoing, each mezzanine lender will have
the right to purchase the related Mortgage Loan and cure defaults relating
thereto as set forth in the related mezzanine intercreditor agreement.

            Section 3.19 Additional Obligations of Master Servicer and Special
Servicer.

            (a) The Master Servicer shall deposit in the Certificate Account on
each P&I Advance Date, without any right of reimbursement therefor with respect
to each Mortgage Loan (other than a Specially Serviced Mortgage Loan and other
than any Mortgage Loan for which the Special Servicer has waived a prepayment
restriction) that was subject to a voluntary Principal Prepayment during the
most recently ended Collection Period creating a Prepayment Interest Shortfall,
an amount equal to the lesser of (i) the amount of the related Prepayment
Interest Shortfall and (ii) the sum of (A) the Master Servicing Fee (calculated
for this purpose only at a rate of 0.01% per annum) received by the Master
Servicer during such Collection Period on such Mortgage Loan and (B) investment
income earned by the Master Servicer on the related Principal Prepayment during
the most recently ended Collection Period; provided, however, to the extent any
such Prepayment Interest Shortfall is the result of the Master Servicer's
failure to enforce the applicable Mortgage Loan documents the amount in clause
(A) shall include the entire Master Servicing Fee on the applicable Mortgage
Loan for such Collection Period.

            (b) The Master Servicer shall, as to each Mortgage Loan which is
secured by the interest of the related Mortgagor under a Ground Lease, promptly
(and in any event within 60 days of the Closing Date) notify the related ground
lessor in writing of the transfer of such Mortgage Loan to the Trust Fund
pursuant to this Agreement and inform such ground lessor that any notices of
default under the related Ground Lease should thereafter be forwarded to the
Master Servicer.

            (c) The Master Servicer shall provide to each Companion Holder any
reports or notices required to be delivered to such Companion Holder pursuant to
the related Intercreditor Agreement.

            (d) With respect to the NGP Rubicon GSA Pool Loan, the Master
Servicer, to the extent permitted under the related Mortgage Loan documents or
related mezzanine loan documents, shall obtain written confirmation from each
Rating Agency that (i) any defeasance of the Mortgaged Property or (ii) any
transfer of the related mezzanine loan which needs to be approved by the
mortgagee will not result in the qualification, downgrade or withdrawal of the
ratings then assigned to the Certificates, which confirmation shall be obtained
at the expense of the related Mortgagor or mezzanine lender, as applicable.

            (e) With respect to each of the 1000 & 1100 Wilson Loan and the
Mortgage Loan identified on the Mortgage Loan Schedule as the 1701 North Fort
Myer Loan (loan number 9), the Master Servicer, to the extent permitted under
the related Mortgage Loan documents, shall obtain written confirmation from each
Rating Agency at the expense of the related Mortgagor that any mezzanine loan
which needs to be approved by the mortgagee will not result in the
qualification, downgrade or withdrawal of the ratings then assigned to the
Certificates.

            (f) With respect to the Westfield San Francisco Centre Loan, the
Master Servicer, to the extent permitted under the related Mortgage Loan
documents, shall provide prompt, advance written notice to each Rating Agency of
any assumption of the Mortgage Loan.

            (g) If a Rating Agency confirmation is required in connection with
any proposed action relating to the NGP Rubicon GSA Pool Loan which would have a
material effect on the NGP Rubicon GSA Pool Pari Passu Companion Loan and if the
NGP Rubicon GSA Pool Pari Passu Companion Loan has been securitized, then the
Master Servicer or the Special Servicer, as applicable, shall also obtain
written confirmation from each rating agency rating the certificates backed by
such securitization that such action will not result in the qualification,
downgrade or withdrawal of the ratings then assigned to such certificates. The
costs of any rating agency confirmation with respect to the NGP Rubicon GSA Pool
Pari Passu Companion Loan shall be borne by the related Companion Holder.

            Section 3.20 Modifications, Waivers, Amendments and Consents.

            (a) Subject to Sections 3.20(b) through 3.20(m) below and further
subject to Sections 3.08(b) and 6.11 and further subject to any applicable
intercreditor agreement or similar agreement, the Master Servicer (to the extent
provided in Section 3.02(a) and Section 3.20(i) below) and the Special Servicer
may, on behalf of the Trustee, agree to any modification, waiver or amendment of
any term of any Mortgage Loan (including, subject to Section 3.20(i), the lease
reviews and lease consents related thereto) without the consent of the Trustee
or any Certificateholder.

            (b) All modifications, waivers or amendments of any Mortgage Loan
(including, subject to Section 3.20(i), the lease reviews and lease consents
related thereto) shall be in writing and shall be considered and effected in
accordance with the Servicing Standard; provided, however, that neither the
Master Servicer nor the Special Servicer, as applicable, shall make or permit or
consent to, as applicable, any modification, waiver or amendment of any term of
any Mortgage Loan not otherwise permitted by this Section 3.20 that would
constitute a "significant modification" of such Mortgage Loan within the meaning
of Treasury Regulations Section 1.860G-2(b).

            (c) Except as provided in 3.20(d) and the last sentence of Section
3.02(a), the Special Servicer, on behalf of the Trustee, shall not agree or
consent to any modification, waiver or amendment of any term of any Mortgage
Loan that would:

                  (i) affect the amount or timing of any related payment of
            principal, interest or other amount (including Prepayment Premiums
            or Yield Maintenance Charges, but excluding Penalty Interest and
            amounts payable as additional servicing compensation) payable
            thereunder;

                  (ii) affect the obligation of the related Mortgagor to pay a
            Prepayment Premium or Yield Maintenance Charge or permit a Principal
            Prepayment during any period in which the related Mortgage Note
            prohibits Principal Prepayments;

                  (iii) except as expressly contemplated by the related Mortgage
            or pursuant to Section 3.09(d), result in a release of the lien of
            the Mortgage on any material portion of the related Mortgaged
            Property without a corresponding Principal Prepayment in an amount
            not less than the fair market value (as determined by an appraisal
            by an Independent Appraiser delivered to the Special Servicer at the
            expense of the related Mortgagor and upon which the Special Servicer
            may conclusively rely) of the property to be released other than in
            connection with a taking of all or part of the related Mortgaged
            Property or REO Property for not less than fair market value by
            exercise of the power of eminent domain or condemnation or casualty
            or hazard losses with respect to such Mortgaged Property or REO
            Property;

                  (iv) if such Mortgage Loan is equal to or in excess of 5% of
            the then aggregate current principal balances of all Mortgage Loans
            or $35,000,000 (or with respect to Moody's $25,000,000), or is one
            of the ten largest Mortgage Loans by Stated Principal Balance as of
            such date, permit the transfer or transfers of (A) the related
            Mortgaged Property or any interest therein or (B) equity interests
            in the borrower or any equity owner of the borrower that would
            result, in the aggregate during the term of the related Mortgage
            Loan, in a transfer greater than 49% of the total interest in the
            borrower and/or any equity owner of the borrower or a transfer of
            voting control in the borrower or an equity owner of the borrower
            without the prior written confirmation from each Rating Agency that
            such changes will not result in the qualification, downgrade or
            withdrawal to the ratings then assigned to the Certificates;

                  (v) allow any additional lien on the related Mortgaged
            Property if such Mortgage Loan is equal to or in excess of 2% of the
            then aggregate current principal balances of the Mortgage Loans or
            $20,000,000, is one of the ten largest Mortgage Loans by Stated
            Principal Balance as of such date, or with respect to S&P only, has
            an aggregate Loan-to-Value Ratio that is equal to or greater than
            85% or has an aggregate Debt Service Coverage Ratio that is less
            than 1.20x, without the prior written confirmation from each Rating
            Agency (as applicable) that such change will not result in the
            qualification, downgrade or withdrawal or the ratings then assigned
            to the Certificates; or

                  (vi) in the reasonable, good faith judgment of the Special
            Servicer, otherwise materially impair the security for such Mortgage
            Loan or reduce the likelihood of timely payment of amounts due
            thereon.

            (d) Notwithstanding Section 3.20(c), but subject to the third
paragraph of this Section 3.20(d), and the rights of the Controlling Class
Representative and the rights (if any) of a Companion Holder pursuant to the
related Intercreditor Agreement, the Special Servicer may (i) reduce the amounts
owing under any Specially Serviced Mortgage Loan by forgiving principal, accrued
interest or any Prepayment Premium or Yield Maintenance Charge, (ii) reduce the
amount of the Periodic Payment on any Specially Serviced Mortgage Loan,
including by way of a reduction in the related Mortgage Rate, (iii) forbear in
the enforcement of any right granted under any Mortgage Note or Mortgage
relating to a Specially Serviced Mortgage Loan, (iv) extend the maturity date of
any Specially Serviced Mortgage Loan, or (v) accept a Principal Prepayment on
any Specially Serviced Mortgage Loan during any Lockout Period; provided that
(A) the related Mortgagor is in default with respect to the Specially Serviced
Mortgage Loan or, in the reasonable, good faith judgment of the Special
Servicer, such default is reasonably foreseeable, and (B) in the reasonable,
good faith judgment of the Special Servicer, such modification would increase
the recovery on the Mortgage Loan to Certificateholders on a net present value
basis (the relevant discounting of amounts that will be distributable to
Certificateholders to be performed at the related Net Mortgage Rate). In the
case of every other modification, waiver or consent, the Special Servicer shall
determine and may rely on an Opinion of Counsel (which Opinion of Counsel shall
be an expense of the Trust Fund to the extent not paid by the related Mortgagor)
to the effect that such modification, waiver or amendment would not both (1)
effect an exchange or reissuance of the Mortgage Loan under Treasury Regulations
Section 1.860G-2(b) of the Code and (2) cause either of REMIC I or REMIC II to
fail to qualify as a REMIC under the Code or result in the imposition of any tax
on "prohibited transactions" or "contributions" after the Startup Day under the
REMIC Provisions.

            In addition, notwithstanding Section 3.20(c), but subject to the
third paragraph of this Section 3.20(d), the Special Servicer may extend the
date on which any Balloon Payment is scheduled to be due in respect of a
Specially Serviced Mortgage Loan if the conditions set forth in the proviso to
the prior paragraph are satisfied and the Special Servicer has obtained an
Appraisal of the related Mortgaged Property, in connection with such extension,
which Appraisal supports the determination of the Special Servicer contemplated
by clause (B) of the proviso to the immediately preceding paragraph.

            In no event will the Special Servicer (i) extend the maturity date
of a Mortgage Loan beyond a date that is two years prior to the Rated Final
Distribution Date, (ii) reduce the Mortgage Rate of a Mortgage Loan to less than
the lesser of (A) the original Mortgage Rate of such Mortgage Loan, (B) the
highest Pass-Through Rate of any Class of Certificates (other than the Class X
Certificates) then outstanding and (C) a rate below the then prevailing interest
rate for comparable loans, as determined by the Special Servicer, (iii) if the
Mortgage Loan is secured by a Ground Lease (and not by the corresponding fee
simple interest), extend the maturity date of such Mortgage Loan beyond a date
which is less than 20 years prior to the expiration of the term of such Ground
Lease; (iv) defer interest due on any Mortgage Loan in excess of 10% of the
Stated Principal Balance of such Mortgage Loan or defer the collection of
interest on any Mortgage Loan without accruing interest on such deferred
interest at a rate at least equal to the Mortgage Rate of such Mortgage Loan.

            The determination of the Special Servicer contemplated by clause (B)
of the proviso to the first paragraph of this Section 3.20(d) shall be evidenced
by an Officer's Certificate to such effect delivered to the Trustee and the
Master Servicer and describing in reasonable detail the basis for the Special
Servicer's determination. The Special Servicer shall append to such Officer's
Certificate any information including but not limited to income and expense
statements, rent rolls, property inspection reports and appraisals that support
such determination.

            (e) Any payment of interest that is deferred pursuant to any
modification, waiver or amendment permitted hereunder, shall not, for purposes
hereof, including, without limitation, calculating monthly distributions to
Certificateholders, be added to the unpaid principal balance or Stated Principal
Balance of the related Mortgage Loan, notwithstanding that the terms of such
modification, waiver or amendment so permit. The foregoing shall in no way limit
the Special Servicer's ability to charge and collect from the Mortgagor costs
otherwise collectible under the terms of the related Mortgage Note and this
Agreement together with interest thereon.

            (f) The Special Servicer or, with respect to clause (i) below, the
Master Servicer may, as a condition to granting any request by a Mortgagor for
consent, modification, waiver or indulgence or any other matter or thing, the
granting of which is within its discretion pursuant to the terms of the
instruments evidencing or securing the related Mortgage Loan and is permitted by
the terms of this Agreement, require that such Mortgagor pay to it (i) as
additional servicing compensation, a reasonable or customary fee for the
additional services performed in connection with such request; provided such fee
would not itself be a "significant modification" pursuant to Treasury
Regulations Section 1.1001-3(e)(2) and (ii) any related costs and expenses
incurred by it. In no event shall the Master Servicer or the Special Servicer be
entitled to payment for such fees or expenses unless such payment is collected
from the related Mortgagor.

            (g) The Special Servicer shall notify the Master Servicer, any
related Sub-Servicers, the Trustee, the Controlling Class Representative, the
Rating Agencies and with respect to any Co-Lender Loan, the related Companion
Holder, in writing, of any material modification, waiver or amendment of any
term of any Mortgage Loan (including fees charged the Mortgagor) and the date
thereof, and shall deliver to the Custodian for deposit in the related Mortgage
File, an original counterpart of the agreement relating to such modification,
waiver or amendment, promptly (and in any event within ten Business Days)
following the execution thereof. Copies of each agreement whereby any such
modification, waiver or amendment of any term of any Mortgage Loan is effected
shall be made available for review upon prior request during normal business
hours at the offices of the Special Servicer pursuant to Section 3.15 hereof.

            (h) The Master Servicer shall not permit defeasance of any Mortgage
Loan to the extent inconsistent with the terms of such Mortgage Loan. With
respect to the 21 West Shopping Center Loan, in the event that the related
borrower has the right to elect to use funds held in the reserve accounts to
repay or partially defease the 21 West Shopping Center Loan, the Master Servicer
shall not permit partial defeasance but shall hold such funds as additional
collateral for such Mortgage Loan. Unless and to the extent the Master Servicer
is precluded from preventing such defeasance by the related Mortgage Loan
documents or otherwise (provided that the Master Servicer shall not allow such
defeasance to cause either of REMIC I or REMIC II created hereunder to fail to
qualify as a REMIC; provided, further, the Master Servicer may rely on an
Opinion of Counsel as provided for in (ii) below), the Master Servicer will not
permit defeasance of any Mortgage Loan, unless: (i) the defeasance collateral
consists of non-callable "Government Securities" within the meaning of the
Investment Company Act of 1940, (ii) the Master Servicer has determined that the
defeasance will not result in an Adverse REMIC Event (provided that the Master
Servicer shall be entitled to rely conclusively on an Opinion of Counsel to that
effect), (iii) the Master Servicer has notified the Rating Agencies, (iv) to the
extent the defeasance of the Mortgage Loan is required by the then current
applicable Rating Agency criteria to be reviewed by a Rating Agency, such Rating
Agency has confirmed that such defeasance will not result in the qualification,
downgrade or withdrawal of the rating then assigned to any Class of Certificates
to which a rating has been assigned by such Rating Agency, (provided that no
confirmation from S&P shall be required if the Mortgage Loan being defeased,
together with all Mortgage Loans cross-collateralized with such Mortgage Loan,
(i) is not one of the ten (10) largest Mortgage Loans (or cross-collateralized
groups of Mortgage Loans) by Stated Principal Balance in the Trust Fund, and
(ii) has a Stated Principal Balance at the time of the defeasance that is less
than $20,000,000 and less than 5% of the aggregate Stated Principal Balance at
the time of the defeasance of the Mortgage Loans and the Master Servicer shall
have delivered a Defeasance Certificate substantially in the form of Exhibit O
hereto), (v) the Master Servicer has requested and received from the related
Mortgagor (A) an Opinion of Counsel generally to the effect that the Trustee
will have a perfected, first priority security interest in such defeasance
collateral and (B) written confirmation from a firm of Independent accountants
stating that payments made on such defeasance collateral in accordance with the
terms thereof will be sufficient to pay the subject Mortgage Loan in full on or
before its Stated Maturity Date and in accordance with the Periodic Payment (or,
in the case of an ARD Loan, on or before its Anticipated Repayment Date) and to
timely pay each Periodic Payment scheduled to be due on or prior thereto but
after the defeasance and (vi) a single purpose entity (as defined below) is
designated to assume the Mortgage Loan and own the defeasance collateral;
provided that, if under the terms of the related Mortgage Loan documents, the
related Mortgagor delivers cash to purchase the defeasance collateral rather
than the defeasance collateral itself, the Master Servicer shall purchase the
U.S. government obligations contemplated by the related Mortgage Loan documents
on behalf of the related Mortgagor. Any customary and reasonable out-of-pocket
expense incurred by the Master Servicer pursuant to this Section 3.20(h) shall
be paid by the Mortgagor of the defeased Mortgage Loan pursuant to the related
Mortgage, Mortgage Note or other pertinent document. Notwithstanding the
foregoing, if at any time, a court with jurisdiction in the matter shall hold
that the related Mortgagor may obtain a release of the subject Mortgaged
Property but is not obligated to deliver the full amount of the defeasance
collateral contemplated by the related Mortgage Loan documents (or cash
sufficient to purchase such defeasance collateral), then the Master Servicer
shall (i) if consistent with the related Mortgage Loan documents, refuse to
allow the defeasance of the Mortgage Loan or (ii) if the Master Servicer cannot
so refuse and if the related Mortgagor has delivered cash to purchase the
defeasance collateral, the Master Servicer shall either (A) buy such defeasance
collateral or (B) prepay the Mortgage Loan, in either case, in accordance with
the Servicing Standard. For purposes of this paragraph, a "single purpose
entity" shall mean a Person, other than an individual, whose organizational
documents provide as follows: it is formed solely for the purpose of owning and
pledging Defeasance Collateral related to one or more of the Mortgage Loans; it
may not engage in any business unrelated to such Defeasance Collateral and the
financing thereof; it does not have and may not own any assets other than those
related to its interest in the Defeasance Collateral or the financing thereof
and may not incur any indebtedness other than as permitted by the related
Mortgage or Mortgages; it shall maintain its own books, records and accounts, in
each case which are separate and apart from the books, records and accounts of
any other person; it shall hold regular meetings, as appropriate, to conduct its
business, and shall observe all entity-level formalities and record keeping; it
shall conduct business in its own name and use separate stationery, invoices and
checks; it may not guarantee or assume the debts or obligations of any other
person; it shall not commingle its assets or funds with those of any other
person; it shall pay its obligations and expenses from its own funds and
allocate and charge reasonably and fairly any common employees or overhead
shared with affiliates; it shall prepare separate tax returns and financial
statements or, if part of a consolidated group, shall be shown as a separate
member of such group; it shall transact business with affiliates on an arm's
length basis pursuant to written agreements; and it shall hold itself out as
being a legal entity, separate and apart from any other person. The single
purpose entity organizational documents shall provide that any dissolution and
winding up or insolvency filing for such entity requires the unanimous consent
of all partners or members, as applicable, and that such documents may not be
amended with respect to the single purpose entity requirements during the term
of the Mortgage Loan.

            (i) For any Mortgage Loan (other than a Specially Serviced Mortgage
Loan and the Non-Serviced Mortgage Loans) and subject to the rights of the
Special Servicer set forth in this Section 3.20, the Master Servicer, without
the consent of the Special Servicer or the Controlling Class Representative
shall be responsible for any request by a Mortgagor for the consent of the
mortgagee for a modification, waiver or amendment of any term with respect to:

                  (i) approving routine leasing activity (including any
            subordination, standstill and attornment agreements) with respect to
            any lease for less than the lesser of (a) 30,000 square feet and (b)
            20% of the related Mortgaged Property;

                  (ii) approving a change of the property manager at the request
            of the related Mortgagor; provided that (A) the successor property
            manager is not affiliated with the Mortgagor and is a nationally or
            regionally recognized manager of similar properties, (B) the related
            Mortgage Loan does not have an outstanding principal balance in
            excess of $5,000,000 and (C) the subject Mortgaged Property does not
            secure a Companion Loan;

                  (iii) approving any waiver affecting the timing of receipt of
            financial statements from any Mortgagor; provided that such
            financial statements are delivered no less than quarterly and within
            60 days of the end of the calendar quarter;

                  (iv) approving annual budgets for the related Mortgaged
            Property; provided that no such budget (1) provides for the payment
            of operating expenses in an amount equal to more than 110% of the
            amounts budgeted therefor for the prior year or (2) provides for the
            payment of any material expenses to any affiliate of the Mortgagor
            (other than the payment of a management fee to any property manager
            if such management fee is no more than the management fee in effect
            on the Cut-Off Date);

                  (v) subject to other restrictions herein regarding Principal
            Prepayments, waiving any provision of a Mortgage Loan requiring a
            specified number of days notice prior to a Principal Prepayment;

                  (vi) approving modifications, consents or waivers (other than
            those set forth in Section 3.20(c)) in connection with a defeasance
            permitted by the terms of the related Mortgage Loan if the Master
            Servicer receives an Opinion of Counsel (which Opinion of Counsel
            shall be an expense of the Mortgagor) to the effect that such
            modification, waiver or consent would not cause any REMIC to fail to
            qualify as a REMIC under the Code or result in a "prohibited
            transaction" under the REMIC Provisions; and

                  (vii) approving certain consents with respect to right-of-ways
            and easements and consent to subordination of the related Mortgage
            Loan to such easements or right-of-ways;

provided, however, if the Mortgage Loan is a Co-Lender Loan, the Master Servicer
shall provide written notice of such modification, waiver and amendment to the
related Companion Holder to the extent required under the related Intercreditor
Agreement; provided, further, that the Master Servicer shall promptly notify the
Special Servicer of any requests not subject to this Section 3.20(i) for which
the Special Servicer is responsible pursuant to this Section 3.20 and shall
deliver to the Special Servicer (which delivery may be by electronic
transmission in a format acceptable to the Master Servicer and Special Servicer)
a copy of the request, and all information in the possession of the Master
Servicer that the Special Servicer may reasonably request related thereto.

            (j) To the extent that either the Master Servicer or Special
Servicer waives any Penalty Interest or late charge in respect of any Mortgage
Loan, whether pursuant to Section 3.02(a) or this Section 3.20, the respective
amounts of additional servicing compensation payable to the Master Servicer and
the Special Servicer under Section 3.11 out of such Penalty Interest or late
payment charges shall be reduced proportionately, based upon the respective
amounts that had been payable thereto out of such Penalty Interest or late
payment charges immediately prior to such waiver.

            (k) Notwithstanding anything to the contrary in this Agreement,
neither the Master Servicer nor the Special Servicer, as applicable, shall take
the following action unless it has received prior written confirmation (the cost
of which shall be paid by the related Mortgagor, if so allowed by the terms of
the related loan documents) from the Rating Agencies that such action will not
result in a qualification, downgrade or withdrawal of any of the ratings
assigned by such Rating Agency to the Certificates:

                  (i) With respect to any Mortgaged Property that secures a
            Mortgage Loan with an unpaid principal balance that is at least
            equal to five percent (5%) of the then aggregate principal balance
            of all Mortgage Loans or $20,000,000, the giving of any consent,
            approval or direction regarding the termination of the related
            property manager or the designation of any replacement property
            manager; and

                  (ii) With respect to each Mortgage Loan with an unpaid
            principal balance that is equal to or greater than (A) two percent
            (2%) of the then aggregate principal balance of all the Mortgage
            Loans or (B) $10,000,000 and which is secured by a Mortgaged
            Property which is a hospitality property, the giving of any consent
            to any change in the franchise affiliation of such Mortgaged
            Property.

            (l) In the event the Special Servicer, in connection with a
modification, waiver or amendment in respect of any Co-Lender Loan (other than a
Non-Serviced Mortgage Loan), modifies, waives or amends the terms thereof such
that (i) the Stated Principal Balance is decreased, (ii) the Mortgage Rate is
reduced, (iii) payments of interest or principal are waived, reduced or deferred
or (iv) any other adjustment is made to any of the terms of such Co-Lender Loan,
all payments made in respect of the related Mortgage Loan shall be made as
though such modification, waiver or amendment did not occur, with the payment
terms of such Co-Lender Loan remaining the same as they are on the related Cut
Off Date, and the related Subordinate Companion Loan(s) shall bear the full
economic effect of all waivers, reductions or deferrals of amounts due on such
Co-Lender Loan attributable to such modification, waiver or amendment.

            (m) Subject to the terms of the related Intercreditor Agreement, the
Master Servicer may extend the maturity date of Mortgage Loans with an original
maturity of five years or less with the approval of the Controlling Class
Representative for up to two one-year extensions.

            Section 3.21 Transfer of Servicing Between Master Servicer and
Special Servicer; Record Keeping.

            (a) Upon determining that a Servicing Transfer Event has occurred
with respect to any Mortgage Loan (other than a Non-Serviced Mortgage Loan), the
Master Servicer or Special Servicer, as applicable, shall promptly notify the
Trustee and Master Servicer or Special Servicer, as applicable, and, if the
Master Servicer is not also the Special Servicer, the Master Servicer shall
immediately deliver or cause to be delivered a copy of the related Mortgage File
and Servicing File, to the Special Servicer and shall use reasonable efforts to
provide the Special Servicer with all information, documents (or copies thereof)
and records (including records stored electronically on computer tapes, magnetic
discs and the like) relating to the Mortgage Loan and, if applicable the related
Companion Loan, either in the Master Servicer's or any of its directors',
officers', employees', affiliates' or agents' possession or control or otherwise
available to the Master Servicer without undue burden or expense, and reasonably
requested by the Special Servicer to enable it to assume its functions hereunder
with respect thereto without acting through a Sub-Servicer. The Master Servicer
shall use reasonable efforts to comply with the preceding sentence within five
Business Days of the occurrence of each related Servicing Transfer Event;
provided, however, if the information, documents and records requested by the
Special Servicer are not contained in the Servicing File, the Master Servicer
shall have such period of time as reasonably necessary to make such delivery.
Notwithstanding the occurrence of a Servicing Transfer Event, the Master
Servicer shall continue to receive payments on such Mortgage Loan (including
amounts collected by the Special Servicer).

            Upon determining that a Specially Serviced Mortgage Loan has become
a Corrected Mortgage Loan and if the Master Servicer is not also the Special
Servicer, the Special Servicer shall immediately give notice thereof to the
Master Servicer, and shall return the related Mortgage File and Servicing File
and all other information, documents and records that were not part of the
Servicing File when it was delivered to the Special Servicer within five
Business Days of the occurrence, to the Master Servicer (or such other Person as
may be directed by the Master Servicer) and upon giving such notice, and
returning such Servicing File, to the Master Servicer (or such other Person as
may be directed by the Master Servicer), the Special Servicer's obligation to
service such Mortgage Loan, and, if applicable, the Companion Loan, and the
Special Servicer's right to receive the Special Servicing Fee with respect to
such Mortgage Loan shall terminate, and the obligations of the Master Servicer
to service and administer such Mortgage Loan and, if applicable, the related
Companion Loan shall resume.

            (b) In servicing any Specially Serviced Mortgage Loans, the Special
Servicer shall provide to the Custodian originals of documents included within
the definition of "Mortgage File" for inclusion in the related Mortgage File
(with a copy of each such original to the Master Servicer), and copies of any
additional related Mortgage Loan information, including correspondence with the
related Mortgagor.

            (c) On or before each Determination Date, the Special Servicer shall
deliver to the Master Servicer and each Rating Agency (or such other Person as
may be directed by the Master Servicer) a statement in writing and in computer
readable format (the form of such statement to be agreed upon by the Master
Servicer) describing, on a loan-by-loan and property-by-property basis, (1)
insofar as it relates to Specially Serviced Mortgage Loans and REO Properties,
the information described in clauses (x) through (xiii) of Section 4.02(a) and,
insofar as it relates to the Special Servicer, the information described in
clauses (xxiii), (xxiv) and (xxv) of Section 4.02(a), (2) the amount of all
payments, Insurance Proceeds and Liquidation Proceeds received, and the amount
of any Realized Loss incurred, with respect to each Specially Serviced Mortgage
Loan during the related Collection Period, and the amount of all REO Revenues,
Insurance Proceeds and Liquidation Proceeds received, and the amount of any
Realized Loss incurred, with respect to each REO Property during the related
Collection Period, (3) the amount, purpose and date of all Servicing Advances
requested by the Special Servicer with respect to each Specially Serviced
Mortgage Loan and REO Property during the related Collection Period and (4) such
additional information relating to the Specially Serviced Mortgage Loans and REO
Properties as the Master Servicer reasonably requests to enable it to perform
its responsibilities under this Agreement. Notwithstanding the foregoing
provisions of this subsection (c), the Master Servicer shall maintain ongoing
payment records with respect to each of the Specially Serviced Mortgage Loans
and REO Properties and shall provide the Special Servicer with any information
reasonably available to the Master Servicer required by the Special Servicer to
perform its duties under this Agreement.

            (d) No later than 60 days after a Mortgage Loan and, if applicable,
Companion Loan becomes a Specially Serviced Mortgage Loan, the Special Servicer
shall deliver to each Rating Agency, the Trustee, the Master Servicer and the
Controlling Class Representative (and, in the case of a Co-Lender Loan, the
related Companion Holder), a report (the "Asset Status Report") with respect to
such Mortgage Loan and the related Mortgaged Property. Such Asset Status Report
shall set forth the following information to the extent reasonably determinable:

                  (i) summary of the status of such Specially Serviced Mortgage
            Loan and negotiations with the related Mortgagor;

                  (ii) a discussion of the legal and environmental
            considerations reasonably known to the Special Servicer, consistent
            with the Servicing Standard, that are applicable to the exercise of
            remedies as aforesaid and to the enforcement of any related
            guaranties or other collateral for the related Specially Serviced
            Mortgage Loan and whether outside legal counsel has been retained;

                  (iii) the most current rent roll and income or operating
            statement available for the related Mortgaged Property;

                  (iv) the Appraised Value of the Mortgaged Property together
            with the assumptions used in the calculation thereof;

                  (v) summary of the Special Servicer's recommended action with
            respect to such Specially Serviced Mortgage Loan; and

                  (vi) such other information as the Special Servicer deems
            relevant in light of the Servicing Standard.

            Any Asset Status Report with respect to a Co-Lender Loan shall also
include any additional information required by the related Intercreditor
Agreement. In addition, with respect to a Co-Lender Loan, the Controlling Class
Representative's approval or disapproval of any actions recommended by such
Asset Status Report relating to such Co-Lender Loan will be subject to the
rights of the related Companion Holder pursuant to the terms of the related
Intercreditor Agreement.

            If within ten (10) Business Days of receiving an Asset Status Report
which relates to a recommended action for which the Controlling Class
Representative is entitled to object under Section 6.11, the Controlling Class
Representative does not disapprove such Asset Status Report in writing, the
Special Servicer shall implement the recommended action as outlined in such
Asset Status Report; provided, however, that the Special Servicer may not take
any action that is contrary to applicable law, the Servicing Standard, or the
terms of the applicable Mortgage Loan documents. If the Controlling Class
Representative disapproves such Asset Status Report, the Special Servicer will
revise such Asset Status Report and deliver to the Controlling Class
Representative, the Rating Agencies and the Master Servicer a new Asset Status
Report as soon as practicable, but in no event later than 30 days after such
disapproval.

            The Special Servicer shall revise such Asset Status Report as
described above in this Section 3.21(d) until the Controlling Class
Representative shall fail to disapprove such revised Asset Status Report in
writing within ten (10) Business Days of receiving such revised Asset Status
Report or until the Special Servicer makes one of the determinations described
below. The Special Servicer may, from time to time, modify any Asset Status
Report it has previously delivered and implement such report; provided such
report shall have been prepared, reviewed and not rejected pursuant to the terms
of this Section. Notwithstanding the foregoing, the Special Servicer (i) may,
following the occurrence of an extraordinary event with respect to the related
Mortgaged Property, take any action set forth in such Asset Status Report (and
consistent with the terms hereof) before the expiration of a ten (10) Business
Day period if the Special Servicer has reasonably determined that failure to
take such action would materially and adversely affect the interests of the
Certificateholders or, if a Loan Pair is involved, the Certificateholders and
the related Companion Holders, (as a collective whole) and it has made a
reasonable effort to contact the Controlling Class Representative and (ii) in
any case, shall determine whether such affirmative disapproval is not in the
best interest of all the Certificateholders pursuant to the Servicing Standard.

            Upon making such determination in clause (ii) of the immediately
preceding paragraph, the Special Servicer shall notify the Trustee of such
rejection and deliver to the Trustee a proposed notice to Certificateholders
which shall include a copy of the Asset Status Report, and the Trustee shall
send such notice to all Certificateholders. If the majority of such
Certificateholders, as determined by Voting Rights, fail, within 5 days of the
Trustee's sending such notice, to reject such Asset Status Report, the Special
Servicer shall implement the same. If the Asset Status Report is rejected by a
majority of the Certificateholders, (other than for a reason which violates the
Servicing Standard, which shall control), the Special Servicer shall revise such
Asset Status Report as described above in this Section 3.21(d) and provide a
copy of such revised report to the Master Servicer. The Trustee shall be
entitled to reimbursement from the Trust Fund for the reasonable expenses of
providing such notices. Notwithstanding the foregoing, the Controlling Class
Representative's approval of or failure to respond to an Asset Status Report
shall not be deemed to be a substitute for any specific consent required
pursuant to Section 6.11(a).

            The Special Servicer shall have the authority to meet with the
Mortgagor for any Specially Serviced Mortgage Loan and take such actions
consistent with the Servicing Standard, the terms hereof and the related Asset
Status Report. The Special Servicer shall not take any action inconsistent with
the related Asset Status Report, unless such action would be required in order
to act in accordance with the Servicing Standard.

            No direction of the Controlling Class Representative or the majority
of the Certificateholders shall (a) require or cause the Special Servicer to
violate the terms of a Specially Serviced Mortgage Loan, applicable law or any
provision of this Agreement, including the Special Servicer's obligation to act
in accordance with the Servicing Standard and to maintain the REMIC status of
REMIC I and REMIC II, (b) result in the imposition of a "prohibited transaction"
or "prohibited contribution" tax under the REMIC Provisions or (c) expose the
Master Servicer, the Special Servicer, the Depositor, any of the Mortgage Loan
Sellers, the Trust Fund or the Trustee or the officers and the directors of each
party to claim, suit or liability or (d) expand the scope of the Master
Servicer's, Trustee's or Special Servicer's responsibilities under this
Agreement. Notwithstanding the foregoing, it is agreed and acknowledged that,
with respect to the Co-Lender Loans, the holders of the Companion Loans have
certain consent and direction rights in the related Intercreditor Agreements,
but nothing herein shall be construed to prevent the Controlling Class
Representative from consulting on a non-binding basis with the Special Servicer
about any applicable Mortgage Loan.

            Section 3.22 Sub-Servicing Agreements.

            (a) The Master Servicer and the Special Servicer (and, with respect
to the Special Servicer, only with the consent of the Controlling Class
Representative) may enter into Sub-Servicing Agreements to provide for the
performance by third parties of any or all of their respective obligations
hereunder; provided that, in each case, the Sub-Servicing Agreement: (i) is
consistent with this Agreement in all material respects, requires the
Sub-Servicer to comply with all of the applicable conditions of this Agreement
and includes events of default with respect to the Sub-Servicer substantially
similar to the Events of Default set forth in Section 7.01(a) hereof (other than
Section 7.01(a)(ix), (x) and (xi) to the extent applicable (modified to apply to
the Sub-Servicer instead of the Master Servicer); (ii) provides that if the
Master Servicer or the Special Servicer, as the case may be, shall for any
reason no longer act in such capacity hereunder (including, without limitation,
by reason of an Event of Default), the Trustee or its designee may thereupon
assume all of the rights and, except to the extent such obligations arose prior
to the date of assumption, obligations of the Master Servicer or the Special
Servicer, as the case may be, under such agreement or (except with respect only
to the Sub-Servicing Agreements in effect as of the date of this Agreement) may
terminate such subservicing agreement without cause and without payment of any
penalty or termination fee (other than the right of reimbursement and
indemnification); (iii) provides that the Trustee, for the benefit of the
Certificateholders, shall be a third party beneficiary under such agreement, but
that (except to the extent the Trustee or its designee assumes the obligations
of the Master Servicer or the Special Servicer, as the case may be, thereunder
as contemplated by the immediately preceding clause (ii) none of the Trustee,
the Trust Fund, any successor Master Servicer or Special Servicer, as the case
may be, or any Certificateholder shall have any duties under such agreement or
any liabilities arising therefrom; (iv) permits any purchaser of a Mortgage Loan
pursuant to this Agreement to terminate such agreement with respect to such
purchased Mortgage Loan at its option and without penalty; (v) with respect to
any Sub-Servicing Agreement entered into by the Special Servicer, does not
permit the Sub-Servicer to enter into or consent to any modification, waiver or
amendment or otherwise take any action on behalf of the Special Servicer
contemplated by Section 3.20 hereof without the consent of such Special Servicer
or conduct any foreclosure action contemplated by Section 3.09 hereof or sale of
a Mortgage Loan or REO Property contemplated by Section 3.18 hereof, and (vi)
does not permit the Sub-Servicer any direct rights of indemnification that may
be satisfied out of assets of the Trust Fund. In addition, each Sub-Servicing
Agreement entered into by the Master Servicer shall provide that such agreement
shall be subject to Section 3.21 hereof with respect to any Mortgage Loan that
becomes a Specially Serviced Mortgage Loan. The Master Servicer and the Special
Servicer shall each deliver to the Trustee and to each other copies of all
Sub-Servicing Agreements, and any amendments thereto and modifications thereof,
entered into by it promptly upon its execution and delivery of such documents.
References in this Agreement to actions taken or to be taken by the Master
Servicer or the Special Servicer include actions taken or to be taken by a
Sub-Servicer on behalf of the Master Servicer or the Special Servicer, as the
case may be; and, in connection therewith, all amounts advanced by any
Sub-Servicer to satisfy the obligations of the Master Servicer or the Special
Servicer hereunder to make P&I Advances or Servicing Advances shall be deemed to
have been advanced by the Master Servicer or the Special Servicer, as the case
may be, out of its own funds and, accordingly, such P&I Advances or Servicing
Advances shall be recoverable by such Sub-Servicer in the same manner and out of
the same funds as if such Sub-Servicer were the Master Servicer or the Special
Servicer, as the case may be. For so long as they are outstanding, Advances
shall accrue interest in accordance with Sections 3.03(d) and 4.03(d), such
interest to be allocable between the Master Servicer or the Special Servicer, as
the case may be, and such Sub-Servicer as they may agree. For purposes of this
Agreement, the Master Servicer and the Special Servicer each shall be deemed to
have received any payment when a Sub-Servicer retained by it receives such
payment. The Master Servicer and the Special Servicer each shall notify the
other, the Trustee and the Depositor in writing promptly of the appointment by
it of any Sub-Servicer.

            (b) Each Sub-Servicer shall be authorized to transact business in
the state or states in which the related Mortgaged Properties it is to service
are situated, if and to the extent required by applicable law.

            (c) The Master Servicer and the Special Servicer, for the benefit of
the Trustee and the Certificateholders, shall (at no expense to the Trustee, the
Certificateholders or the Trust Fund) monitor the performance and enforce the
obligations of their respective Sub-Servicers under the related Sub-Servicing
Agreements. Such enforcement, including, without limitation, the legal
prosecution of claims, termination of Sub-Servicing Agreements in accordance
with their respective terms and the pursuit of other appropriate remedies, shall
be in such form and carried out to such an extent and at such time as the Master
Servicer or the Special Servicer, as applicable, in its good faith business
judgment, would require were it the owner of the Mortgage Loans. Subject to the
terms of the related Sub-Servicing Agreement, the Master Servicer and the
Special Servicer may each have the right to remove a Sub-Servicer at any time it
considers such removal to be in the best interests of Certificateholders.

            (d) In the event of the resignation, removal or other termination of
Wachovia Bank, National Association, or any successor Master Servicer hereunder
for any reason, the Trustee or other Person succeeding such resigning, removed
or terminated party as Master Servicer, shall elect, with respect to any
Sub-Servicing Agreement in effect as of the date of this Agreement: (i) to
assume the rights and obligations of the Master Servicer under such
Sub-Servicing Agreement and continue the sub-servicing arrangements thereunder
on the same terms (including without limitation the obligation to pay the same
sub-servicing fee); (ii) to enter into a new Sub-Servicing Agreement with such
Sub-Servicer on such terms as the Trustee or other successor Master Servicer and
such Sub-Servicer shall mutually agree (it being understood that such
Sub-Servicer is under no obligation to accept any such new Sub-Servicing
Agreement or to enter into or continue negotiations with the Trustee or other
successor Master Servicer in which case the existing Sub-Servicing Agreement
shall remain in effect); or (iii) to terminate the Sub-Servicing Agreement if an
Event of Default (as defined in such Sub-Servicing Agreement) has occurred and
is continuing or otherwise in accordance with the Sub-Servicing Agreement, in
each case without paying any sub-servicer termination fee.

            Each Sub-Servicing Agreement will provide, among other things, that
the Master Servicer and its successors may at its sole option, terminate any
rights the Sub-Servicer may have thereunder with respect to any or all Mortgage
Loans if S&P, Fitch or Moody's (i) reduces the rating assigned to one or more
Classes of the respective Certificates as a result of the sub-servicing of the
Mortgage Loans by the Sub-Servicer, or (ii) advises the Master Servicer or the
Trustee in writing that it will cause a qualification, downgrade or withdrawal
of such rating due to the continued servicing by the Sub-Servicer.

            (e) Notwithstanding any Sub-Servicing Agreement, the Master Servicer
and the Special Servicer shall remain obligated and liable to the Trustee and
the Certificateholders for the performance of their respective obligations and
duties under this Agreement in accordance with the provisions hereof to the same
extent and under the same terms and conditions as if each alone were servicing
and administering the Mortgage Loans or REO Properties for which it is
responsible.

            (f) The Special Servicer shall not enter into a Sub-Servicing
Agreement unless it receives the consent of the Controlling Class Representative
and each Rating Agency has confirmed in writing that the execution of such
agreement will not result in a qualification, downgrade, or withdrawal of the
then-current ratings on the outstanding Certificates or such Sub-Servicing
Agreement relates to a Mortgage Loan or Mortgage Loans (along with any Mortgage
Loans previously sub-serviced pursuant to this section) that represent less than
25% of the outstanding principal balance of all Specially Serviced Mortgage
Loans. The Special Servicer shall comply with the terms of each such
Sub-Servicing Agreement to the extent the terms thereof are not inconsistent
with the terms of this Agreement and the Special Servicer's obligations
hereunder.

            (g) In addition, with respect to the Westfield San Francisco Centre
Loan and the NGP Rubicon GSA Pool Loan, if any Event of Default on the part of
the Master Servicer occurs under this Agreement that materially and adversely
affects the related Companion Holder, and the Master Servicer is not otherwise
terminated in accordance with the terms of this Agreement, the related Companion
Holder has the right to request, and the Master Servicer shall be required to
appoint, a sub-servicer with respect to the Westfield San Francisco Centre Loan
or the NGP Rubicon GSA Pool Loan, as described in Section 7.01(d).

            default (or an event which, with notice or lapse of time, or both,
            would constitute a default) under, or result in the breach of, any
            material agreement or other material instrument to which it is a
            party or by which it is bound.

                  (iii) The Master Servicer has the full power and authority to

            or any order, regulation or demand of any federal, state or local
            governmental or regulatory authority, which violation, in the Master
            Servicer's good faith and reasonable judgment, is likely to affect

            consolidated basis.

            of the initial Master Servicer, the consolidated net worth thereof
            and of its direct or indirect parent), determined in accordance with
            generally accepted accounting principles, is not less than
            $15,000,000.

                  (ix) Any consent, approval, authorization or order of any

            Agreement or, in CWCapital Asset Management LLC's good faith and
            reasonable judgment, is likely to materially and adversely affect
            either the ability of CWCapital Asset Management LLC to perform its
            obligations under this Agreement or the financial condition of
            CWCapital Asset Management LLC.

execution and delivery of this Agreement and shall inure to the benefit of the
Persons for whose benefit they were made for so long as the Trust Fund remains

foregoing representations and warranties, the party discovering such breach
shall give prompt written notice to the other parties hereto.

            Section 3.24 Sub-Servicing Agreement Representation and Warranty.

            The Master Servicer, in such capacity, hereby represents and
warrants to the Trustee, for its own benefit and the benefit of the
Certificateholders, and to the Depositor and the Special Servicer, as of the
Closing Date, that each Sub-Servicing Agreement satisfies the requirements for
such Sub-Servicing Agreements set forth in Sections 3.22(a) and the second
paragraph of 3.22(d) in all material respects.

            Section 3.25 Designation of Controlling Class Representative.

            (a) The Holders (or, in the case of Book-Entry Certificates, the
Certificate Owners) of Certificates representing more than 50% of the Class
Principal Balance of the Controlling Class shall be entitled in accordance with
this Section 3.25 to select a representative having the rights and powers
specified in this Agreement (including those specified in Section 6.11) or to
replace an existing Controlling Class Representative. The advisor referred to
above is referred to herein as the "Controlling Class Representative". Upon (i)
the receipt by the Trustee of written requests for the selection of a
Controlling Class Representative from the Holders (or, in the case of Book-Entry
Certificates, the Certificate Owners) of Certificates representing more than 50%
of the Class Principal Balance of the Controlling Class, (ii) the resignation or
removal of the Person acting as Controlling Class Representative or (iii) a
determination by the Trustee that the Controlling Class has changed, the Trustee
shall promptly notify the Depositor and the Holders (and, in the case of
Book-Entry Certificates, to the extent actually known to a Responsible Officer
of the Trustee or identified thereto by the Depository or the Depository
Participants, the Certificate Owners) of the Controlling Class that they may
select a Controlling Class Representative. Such notice shall set forth the
process for selecting a Controlling Class Representative, which shall be the
designation of the Controlling Class Representative by the Holders (or
Certificate Owners) of Certificates representing more than 50% of the Class
Principal Balance of the Controlling Class by a writing delivered to the
Trustee. No appointment of any Person as a Controlling Class Representative
shall be effective until such Person provides the Trustee and the Master
Servicer with written confirmation of its acceptance of such appointment, an
address and telecopy number for the delivery of notices and other correspondence
and a list of officers or employees of such Person with whom the parties to this
Agreement may deal (including their names, titles, work addresses and telecopy
numbers). Cadim TACH inc. shall be the initial Controlling Class Representative
without need for further designation or notice.

            Notwithstanding anything in this Section 3.25(a), the holders of the
Companion Loans have certain consent and direction rights pursuant to the terms
of the related Intercreditor Agreements as incorporated in this Agreement, and
this Section shall not supercede any such rights, but nothing herein shall be
construed to limit the right of the Controlling Class Representative to consult
on a non-binding basis with the Special Servicer about any applicable Mortgage
Loan.

            (b) Within ten (10) Business Days (or as soon thereafter as
practicable if the Controlling Class consists of Book-Entry Certificates) of
receiving a request therefor from the Master Servicer or Special Servicer, the
Trustee shall, to the extent in its possession, deliver to the requesting party
the identity of the Controlling Class Representative and a list of each Holder
(or, in the case of Book-Entry Certificates, to the extent actually known to a
Responsible Officer of the Trustee or identified thereto by the Depository or
the Depository Participants, each Certificate Owner) of the Controlling Class,
including, in each case, names and addresses. With respect to such information,
the Trustee shall be entitled to conclusively rely on information provided to it
by the Depository, and the Master Servicer and the Special Servicer shall be
entitled to rely on such information provided by the Trustee with respect to any
obligation or right hereunder that the Master Servicer and the Special Servicer
may have to deliver information or otherwise communicate with the Controlling
Class Representative or any of the Holders (or, if applicable, Certificate
Owners) of the Controlling Class. In addition to the foregoing, within two (2)
Business Days of the selection, resignation or removal of a Controlling Class
Representative, the Trustee shall notify the other parties to this Agreement of
such event. The expenses incurred by the Trustee in connection with obtaining
information from the Depository or Depository Participants with respect to any
Book-Entry Certificate shall be expenses of the Trust Fund payable out of the
Certificate Account pursuant to Section 3.05(a).

            (c) A Controlling Class Representative may at any time resign as
such by giving written notice to the Trustee and to each Holder (or, in the case
of Book-Entry Certificates, Certificate Owner) of the Controlling Class. The
Holders (or, in the case of Book-Entry Certificates, the Certificate Owners) of
Certificates representing more than 50% of the Class Principal Balance of the
Controlling Class shall be entitled to remove any existing Controlling Class
Representative by giving written notice to the Trustee and to such existing
Controlling Class Representative.

            (d) Once a Controlling Class Representative has been selected
pursuant to this Section 3.25, each of the parties to this Agreement and each
Certificateholder (or Certificate Owner, if applicable) shall be entitled to
rely on such selection unless a majority of the Holders (or, in the case of
Book-Entry Certificates, the Certificate Owners) of the Controlling Class, by
aggregate Certificate Principal Balance, or such Controlling Class
Representative, as applicable, shall have notified the Trustee and each other
Holder (or, in the case of Book-Entry Certificates, Certificate Owner) of the
Controlling Class, in writing, of the resignation or removal of such Controlling
Class Representative.

            (e) Any and all expenses of the Controlling Class Representative
shall be borne by the Holders (or, if applicable, the Certificate Owners) of
Certificates of the Controlling Class, pro rata according to their respective
Percentage Interests in such Class, and not by the Trust Fund. Notwithstanding
the foregoing, if a claim is made against the Controlling Class Representative
by a Mortgagor with respect to this Agreement or any particular Mortgage Loan,
the Controlling Class Representative shall immediately notify the Trustee, the
Master Servicer and the Special Servicer, whereupon (if the Special Servicer or
the Trust Fund are also named parties to the same action and, in the reasonable
judgment of the Special Servicer, (i) the Controlling Class Representative had
acted in good faith, without negligence or willful misfeasance with regard to
the particular matter, and (ii) there is no potential for the Special Servicer
or the Trust Fund to be an adverse party in such action as regards the
Controlling Class Representative) the Special Servicer on behalf of the Trust
Fund shall, subject to Section 6.03, assume the defense of any such claim
against the Controlling Class Representative. This provision shall survive the
termination of this Agreement and the termination or resignation of the
Controlling Class Representative.

            (f) All rights to, and requirements for, information or notice
(including, but not limited to the delivery of information, notice or access to
information) provided to the Controlling Class Representative or
Certificateholders, in general contained in this Agreement shall also apply to
each Companion Holder (provided such Companion Holder is not a Mortgagor or an
affiliate of a Mortgagor) with respect to information relating to the related
Co-Lender Loan (but, in the case of information relating to a Co-Lender Loan,
excluding the fair value determination thereof).

            Section 3.26 Companion Paying Agent.

            (a) The Master Servicer shall be the initial Companion Paying Agent
hereunder. The Companion Paying Agent undertakes to perform such duties and only
such duties as are specifically set forth herein. The Companion Paying Agent
shall promptly make available to the Companion Holders (other than the holders
of the Companion Loans relating to the 2005-C19 Serviced Mortgage Loan, the
LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI 2005-HQ6 Serviced Mortgage
Loan) all reports available to the Companion Paying Agent that the Trustee has
made available to Certificateholders under this Agreement.

            (b) No provision of this Agreement shall be construed to relieve the
Companion Paying Agent from liability for its own negligent failure to act, bad
faith or its own willful misfeasance; provided, however, that the duties and
obligations of the Companion Paying Agent shall be determined solely by the
express provisions of this Agreement, the Companion Paying Agent shall not be
liable except for the performance of such duties and obligations, no implied
covenants or obligations shall be read into this Agreement against the Companion
Paying Agent and, in the absence of bad faith on the part of the Companion
Paying Agent, the Companion Paying Agent may conclusively rely, as to the truth
and correctness of the statements or conclusions expressed therein, upon any
resolutions, certificates, statements, opinions, reports, documents, orders or
other instrument furnished to the Companion Paying Agent by any Person and which
on their face do not contradict the requirements of this Agreement.

            (c) If the Companion Paying Agent is also the Master Servicer, upon
the resignation or removal of the Master Servicer pursuant to this Agreement,
the Companion Paying Agent shall be deemed simultaneously to resign or be
removed.

            (d) This Section shall survive the termination of this Agreement or
the resignation or removal of the Companion Paying Agent, as regards rights
accrued prior to such resignation or removal.

            Section 3.27 Companion Register.

            The Companion Paying Agent shall maintain a register (the "Companion
Register") on which it will record the names and addresses of, and wire transfer
instructions for, the Companion Holders (other than the holders of the
Non-Serviced Companion Loans) from time to time, to the extent such information
is provided in writing to it by the Companion Holder. Each initial Companion
Holder, along with its name, address, wiring instructions and tax identification
number, is listed on Exhibit L hereto. The Companion Holders shall inform the
Companion Paying Agent and the Master Servicer of the name, address, wiring
instructions and taxpayer identification number of any subsequent Companion
Holders upon any transfer of a Companion Loan. Upon the sale of a Companion Loan
or portion thereof, the transferring Companion Holder shall inform the Companion
Paying Agent and the Master Servicer in writing that such transfer has taken
place and provide the Companion Paying Agent and the Master Servicer with the
name, address, wiring instructions and tax identification number of the
transferee. In the event the Companion Holder transfers a Companion Loan without
notice to the Companion Paying Agent, the Companion Paying Agent shall have no
liability for any misdirected payment in the related Companion Loan and shall
have no obligation to recover and redirect such payment.

            The Companion Paying Agent shall promptly provide the name and
address of the Companion Holders to any party hereto or any successor Companion
Holders upon written request and any such Person may, without further
investigation, conclusively rely upon such information. The Companion Paying
Agent shall have no liability to any Person for the provision of any such names
and addresses.

            Section 3.28 Class A-3SF Swap Contract

            (a) On or before the Closing Date, the Trustee, not in its
individual capacity but solely in its capacity as Trustee, on behalf of the
Trust, shall enter into the Class A-3SF Swap Contract and related agreements
with the Class A-3SF Swap Counterparty. The Paying Agent shall perform the
duties and obligations of the Trustee under the Class A-3SF Swap Contract.

            (b) Not later than 11:00 a.m. New York City time, on the Business
Day prior to each Distribution Date, based on the CMSA Loan Periodic Update File
for the related Collection Period provided by the Master Servicer pursuant to
Section 4.01(b), information obtained by the Paying Agent from the Class A-3SF
Swap Counterparty pursuant to the Class A-3SF Swap Contract, and subject to the
priorities set forth in Sections 4.01(a), 4.01(b) and 4.01(m) hereof, the Paying
Agent shall (i) calculate the Class A-3SF Fixed Swap Payment, if any, and the
Class A-3SF Floating Swap Payment, if any, in accordance with the terms of the
Class A-3SF Swap Contract and this Agreement, and (ii) notify the Class A-3SF
Swap Counterparty of any Class A-3SF Floating Swap Payment or Class A-3SF Net
Swap Payment. In the event the Trustee (or the Paying Agent on behalf of the
Trust) fails to receive any Class A-3SF Floating Swap Payment payable by the
Class A-3SF Swap Counterparty on the Business Day prior to the related
Distribution Date, the Trustee (or Paying Agent) shall provide the Class A-3SF
Swap Counterparty with notice of such non-payment no later than 5:00 p.m. New
York City time on such date. On the related Distribution Date following such
notice of non-payment, if the Trustee fails to receive the Class A-3SF Floating
Swap Payment by 11:00 a.m. New York City time on such Distribution Date, a Class
A-3SF Swap Default and a Class A-3SF Distribution Conversion shall occur on such
Distribution Date.

            (c) On each Distribution Date, the Paying Agent shall remit the
Class A-3SF Net Swap Payment, if any, to the Class A-3SF Swap Counterparty from
the Class A-3SF Floating Rate Account; provided, that upon and during the
continuation of a Class A-3SF Distribution Conversion, the Paying Agent shall
not make such payments to the Class A-3SF Swap Counterparty. Promptly upon
receipt of any payment or other receipt in respect of the Class A-3SF Swap
Contract, the Paying Agent shall deposit the same into the Class A-3SF Floating
Rate Account.

            (d) The Trustee (or the Paying Agent on the behalf of the Trust)
shall at all times enforce the Trust's rights under the Class A-3SF Swap
Contract. In the event of a Class A-3SF Swap Default, the Trustee (or the Paying
Agent on its behalf) shall promptly provide written notice to the Holders of the
Class A-3SF Certificates and shall be required to take such actions (following
the expiration of any applicable grace period specified in the Class A-3SF Swap
Contract), unless otherwise directed in writing by the holders of 25% by
Certificate Balance of the Class A-3SF Certificates, to enforce the rights of
the Trust under the Class A-3SF Swap Contract as may be permitted by the terms
thereof, including termination thereof, and use Class A-3SF Swap Termination
Fees, if any, received from the Class A-3SF Swap Counterparty to enter into a
replacement interest rate swap contract on substantially identical terms or on
such other terms reasonably acceptable to the Trustee (or the Paying Agent on
its behalf), with a replacement swap counterparty that would not cause a Rating
Agency Trigger Event, subject, in each case, to written confirmation by the
Rating Agencies that such action will not result in a qualification, downgrade
or withdrawal of the then current ratings of the Certificates. If the costs
attributable to entering into a replacement interest rate swap contract would
exceed the amount of any Class A-3SF Swap Termination Fees, a replacement
interest rate swap contract shall not be entered into and any such proceeds will
instead be distributed to the holders of the Class A-3SF Certificates on the
immediately succeeding Distribution Date. Notwithstanding anything to the
contrary in this Agreement or the Class A-3SF Swap Contract, the Trustee shall
be under no obligation to take any action to enforce the rights of the Trust
Fund under the Class A-3SF Swap Contract unless it is assured, in its sole
discretion, that the costs and expenses of such action(s) will be reimbursed or
indemnified by the Holders of the Class A-3SF Certificates or any other party
(other than the Trust Fund).

            Any Class A-3SF Distribution Conversion shall become permanent
following the determination by the Trustee (or the Paying Agent acting on its
behalf) not to enter into a replacement interest rate swap contract and
distribution of any Class A-3SF Swap Termination Fees to the Holders of the
Class A-3SF Certificates. Any such Class A-3SF Swap Default (or termination of
the Class A-3SF Swap Contract) and the resulting Class A-3SF Distribution
Conversion shall not, in and of itself, constitute an Event of Default under
this Agreement.

            Upon any change (or notification to the Paying Agent that such
change is imminent) in the payment terms on the Class A-3SF Certificates,
including as a result of a Class A-3SF Distribution Conversion, termination of a
Class A-3SF Distribution Conversion, a Class A-3SF Swap Default or the cure of a
Class A-3SF Swap Default, the Paying Agent shall promptly notify the Depositor
of the change in payment terms.

            (e) In the event that the Class A-3SF Swap Contract is terminated
and no replacement Class A-3SF Swap Contract is entered into, the Paying Agent
shall provide notice of such termination to the Class A-3SF Certificateholders,
which notice shall include: "The Class A-3SF Swap Contract with respect to the
Class A-3SF Certificates is terminated as of [date]. Certificateholders and
beneficial owners that are Plans are advised that the Exemptions will no longer
apply to the Class A-3SF Certificates, effective 60 days after the receipt of
this notice. All capitalized terms used in this notice shall have the meaning
assigned to them in the Pooling and Servicing Agreement."

            (f) The Paying Agent's obligation to pay to the Class A-3SF Swap
Counterparty any funds under the Class A-3SF Swap Contract shall be limited to
the provisions of Section 3.05(h) and in accordance with the priorities set
forth herein; the Trustee will have no obligation on behalf of the Trust Fund to
pay or cause to be paid to the Class A-3SF Swap Counterparty any portion of the
amounts due to the Class A-3SF Swap Counterparty under the Class A-3SF Swap
Contract for any Distribution Date unless and until the related interest payment
on the Class A-3SF Regular Interest for such Distribution Date is actually
received by the Trustee.

            (g) Any costs and expenses related to the Class A-3SF Swap Contract
will not be payable from the Class A-3SF Floating Rate Account of the Trust and
will not constitute Additional Trust Fund Expenses. No party hereunder shall
advance any Class A-3SF Floating Swap Payments. Simultaneous with the delivery
to the Certificateholders, the Trustee shall (1) make available to the Class
A-3SF Swap Counterparty the Distribution Date Statement (as defined in the Class
A-3SF Swap Contract) and (2) make available or deliver to the Class A-3SF Swap
Counterparty copies of any other reports or notices delivered to the Class A-3SF
Certificateholders as and to the extent required by the Class A-3SF Swap
Contract.

            Section 3.29 Class A-MFL Swap Contract

            (a) On or before the Closing Date, the Trustee, not in its
individual capacity but solely in its capacity as Trustee, on behalf of the
Trust, shall enter into the Class A-MFL Swap Contract and related agreements
with the Class A-MFL Swap Counterparty. The Paying Agent shall perform the
duties and obligations of the Trustee under the Class A-MFL Swap Contract.

            (b) Not later than 11:00 a.m. New York City time, on the Business
Day prior to each Distribution Date, based on the CMSA Loan Periodic Update File
for the related Collection Period provided by the Master Servicer pursuant to
Section 4.01(b), information obtained by the Paying Agent from the Class A-MFL
Swap Counterparty pursuant to the Class A-MFL Swap Contract, and subject to the
priorities set forth in Sections 4.01(a), 4.01(b) and 4.01(l) hereof, the Paying
Agent shall (i) calculate the Class A-MFL Fixed Swap Payment, if any, and the
Class A-MFL Floating Swap Payment, if any, in accordance with the terms of the
Class A-MFL Swap Contract and this Agreement, and (ii) notify the Class A-MFL
Swap Counterparty of any Class A-MFL Floating Swap Payment or Class A-MFL Net
Swap Payment. In the event the Trustee (or the Paying Agent on behalf of the
Trust) fails to receive any Class A-MFL Floating Swap Payment payable by the
Class A-MFL Swap Counterparty on the Business Day prior to the related
Distribution Date, the Trustee (or Paying Agent) shall provide the Class A-MFL
Swap Counterparty with notice of such non-payment no later than 5:00 p.m. New
York City time on such date. On the related Distribution Date following such
notice of non-payment, if the Trustee fails to receive the Class A-MFL Floating
Swap Payment by 11:00 a.m. New York City time on such Distribution Date, a Class
A-MFL Swap Default and a Class A-MFL Distribution Conversion shall occur on such
Distribution Date.

            (c) On each Distribution Date, the Paying Agent shall remit the
Class A-MFL Net Swap Payment, if any, to the Class A-MFL Swap Counterparty from
the Class A-MFL Floating Rate Account; provided, that upon and during the
continuation of a Class A-MFL Distribution Conversion, the Paying Agent shall
not make such payments to the Class A-MFL Swap Counterparty. Promptly upon
receipt of any payment or other receipt in respect of the Class A-MFL Swap
Contract, the Paying Agent shall deposit the same into the Class A-MFL Floating
Rate Account.

            On each Distribution Date during a Class X-C Pass-Through Rate
Reduction Period, the Paying Agent shall remit the Class A-MFL Swap Counterparty
Special Payment required, if any, to the Class A-MFL Swap Counterparty from the
Certificate Account. To the extent that this Section 3.29(c) conflicts with
Section 3.05(a) of this Agreement, this section shall control.

            (d) The Trustee (or the Paying Agent on the behalf of the Trust)
shall at all times enforce the Trust's rights under the Class A-MFL Swap
Contract. In the event of a Class A-MFL Swap Default, the Trustee (or the Paying
Agent on its behalf) shall promptly provide written notice to the Holders of the
Class A-MFL Certificates and shall be required to take such actions (following
the expiration of any applicable grace period specified in the Class A-MFL Swap
Contract), unless otherwise directed in writing by the holders of 25% by
Certificate Balance of the Class A-MFL Certificates, to enforce the rights of
the Trust under the Class A-MFL Swap Contract as may be permitted by the terms
thereof, including termination thereof, and use Class A-MFL Swap Termination
Fees, if any, received from the Class A-MFL Swap Counterparty to enter into a
replacement interest rate swap contract on substantially identical terms or on
such other terms reasonably acceptable to the Trustee (or the Paying Agent on
its behalf), with a replacement swap counterparty that would not cause a Rating
Agency Trigger Event, subject, in each case, to written confirmation by the
Rating Agencies that such action will not result in a qualification, downgrade

attributable to entering into a replacement interest rate swap contract would
exceed the amount of any Class A-MFL Swap Termination Fees, a replacement
interest rate swap contract shall not be entered into and any such proceeds will
instead be distributed to the holders of the Class A-MFL Certificates on the
immediately succeeding Distribution Date. Notwithstanding anything to the

be under no obligation to take any action to enforce the rights of the Trust
Fund under the Class A-MFL Swap Contract unless it is assured, in its sole
discretion, that the costs and expenses of such action(s) will be reimbursed or
indemnified by the Holders of the Class A-MFL Certificates or any other party
(other than the Trust Fund).

            Any Class A-MFL Distribution Conversion shall become permanent
following the determination by the Trustee (or the Paying Agent acting on its
behalf) not to enter into a replacement interest rate swap contract and
distribution of any Class A-MFL Swap Termination Fees to the Holders of the
Class A-MFL Certificates. Any such Class A-MFL Swap Default (or termination of
the Class A-MFL Swap Contract) and the resulting Class A-MFL Distribution
Conversion shall not, in and of itself, constitute an Event of Default under
this Agreement.

            Upon any change (or notification to the Paying Agent that such
change is imminent) in the payment terms on the Class A-MFL Certificates,
including as a result of a Class A-MFL Distribution Conversion, termination of a
Class A-MFL Distribution Conversion, a Class A-MFL Swap Default or the cure of a
Class A-MFL Swap Default, the Paying Agent shall promptly notify the Depositor
of the change in payment terms.

            (e) In the event that the Class A-MFL Swap Contract is terminated
and no replacement Class A-MFL Swap Contract is entered into, the Paying Agent

Counterparty any funds under the Class A-MFL Swap Contract shall be limited to
the provisions of Section 3.05(i) and in accordance with the priorities set
forth herein; the Trustee will have no obligation on behalf of the Trust Fund to

            Section 4.01 Distributions.

            (a) On each Distribution Date the Paying Agent shall (except as

      Distribution Date) equal to the entire Principal Distribution Amount for
      such Distribution Date (net of any portion thereof distributed on such
      Distribution Date to the Holders of any other Class of Certificates and/or
      the Class A-3SF Regular Interest and/or the Class A-MFL Regular Interest
      pursuant to any prior clause of this Section 4.01(a));

            (lxi) to distributions to the Holders of the Class P Certificates,
      in an amount equal to, and in reimbursement of, all Realized Losses and
      Additional Trust Fund Expenses, if any, previously allocated to the Class
      P Certificates and not previously reimbursed; and

            (lxii) to make distributions to the Holders of the Class R-II
      Certificates, in an amount equal to the excess, if any, of (A) the
      aggregate distributions deemed made in respect of the REMIC I Regular
      Interests on such Distribution Date pursuant to Section 4.01(h), over (B)
      the aggregate distributions made in respect of the Regular Certificates
      and/or the Class A-3SF Regular Interest and/or the Class A-MFL Regular
      Interest on such Distribution Date pursuant to clauses (i) through (lxi)
      above;

provided that on each Distribution Date after the aggregate of Class Principal
Balances of each Class of Subordinated Certificates have been reduced to zero,
but any two or more of the Class A-1 Certificates, the Class A-2 Certificates,
the Class A-4 Certificates, the Class A-5 Certificates, the Class A-6A
Certificates, the Class A-6B Certificates, the Class A-PB Certificates, the
Class A-7 Certificates, the Class A-1A Certificates and/or the Class A-3SF
Regular Interest remain outstanding, the payments of principal to be made as
contemplated by clauses (iii) through (xii) above with respect to the Class A
Certificates and the Class A-3SF Regular Interest will be made to the Holders of
the respective Classes of such Class A Certificates (other than the Class A-3SF
Certificates) and the Class A-3SF Regular Interest up to an amount equal to, and
pro rata as among such Classes in accordance with, the respective then
outstanding Class Principal Balances of such Classes of Certificates and the
Class A-3SF Regular Interest and without regard to the Principal Distribution
Amount for such Distribution Date and without regard to Loan Group.
Distributions in reimbursement of Realized Losses and Additional Trust Fund
Expenses previously allocated to a Class of Certificates, the Class A-3SF
Regular Interest or the Class A-MFL Regular Interest shall not constitute
distributions of principal and shall not result in reduction of the related
Class Principal Balance.

            All distributions of interest made in respect of the Class X-C and
Class X-P Certificates on any Distribution Date pursuant to clause (i) above,
shall be deemed to have been made in respect of all the Components of such
Class, pro rata in accordance with the respective amounts of interest that would
be payable on such Components on such Distribution Date based on the Class X-C
Strip Rate and Class X-P Strip Rate, as applicable, of such Component multiplied
by its Component Notional Amount, together with any amounts thereof remaining
unpaid from previous Distribution Dates.

            (b) On each Distribution Date, the Paying Agent shall withdraw from
the Distribution Account any amounts that represent Prepayment Premiums and/or
Yield Maintenance Charges actually collected on the Mortgage Loans and any REO
Loans during the related Collection Period and shall be deemed to distribute
such Prepayment Premiums and/or Yield Maintenance Charges from REMIC I to REMIC
II in respect of REMIC I Regular Interest LA-1-1 (whether or not such Class has
received all distributions of interest and principal to which it is entitled),
and then shall distribute each such Prepayment Premium and/or Yield Maintenance
Charge, as additional yield, as follows:

            (i) First, to the Holders of the respective Classes of Regular
      Certificates (other than any Excluded Class thereof), the Class A-3SF
      Regular Interest and the Class A-MFL Regular Interest entitled to
      distributions of principal pursuant to Section 4.01(a) on such
      Distribution Date, up to an amount equal to, and pro rata based on, the
      Additional Yield Amounts for each such Class of Certificates, the Class
      A-3SF Regular Interest and the Class A-MFL Regular Interest for such
      Distribution Date; and

            (ii) Second, (A) on or before the Distribution Date in August 2012,
      44% of such Yield Maintenance Charges and/or Prepayment Premiums to the
      Holders of the Class X-P Certificates and 56% of such Yield Maintenance
      Charges and/or Prepayment Premiums to the Holders of the Class X-C
      Certificates and (B) after the Distribution Date in August 2012, 100% to
      the Holders of the Class X-C Certificates, in each case, to the extent of
      any remaining portion of such Yield Maintenance Charges and/or Prepayment
      Premiums.

            Any distribution of Additional Yield Amounts in respect of the Class
A-3SF Regular Interest and the Class A-MFL Regular Interest shall be paid to the
related Swap Counterparty or to the Holders of the Class A-3SF Certificates and
the Class A-MFL Certificates, respectively, as specified in Section 4.01(j)(ii).

            On each Distribution Date, the Paying Agent shall withdraw from the
Additional Interest Account any amounts that represent (A) Additional Interest
actually collected during the related Collection Period on the ARD Loans and any
related REO Loans and shall distribute such amounts among the Holders of the
Class Z Certificates pro rata in accordance with the respective Percentage
Interests of such Class, and (B) interest and investment income, if any, earned
in respect of amounts held in the Additional Interest Account as provided in
Section 3.06, but only to the extent of the Net Investment Earnings with respect
to such account for the related Distribution Date, and shall distribute such
amount to the Trustee as additional compensation.

            (c) All distributions made with respect to each Class on each
Distribution Date shall be allocated pro rata among the outstanding Certificates
in such Class based on their respective Percentage Interests. Except as
otherwise provided below, all such distributions with respect to each Class on
each Distribution Date shall be made to the Certificateholders of the respective
Class of record at the close of business on the related Record Date and shall be
made by wire transfer of immediately available funds to the account of any such
Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided the Paying Agent with
wiring instructions no less than five Business Days prior to the related Record
Date (which wiring instructions may be in the form of a standing order
applicable to all subsequent Distribution Dates), or otherwise by check mailed
to the address of such Certificateholder as it appears in the Certificate
Register. The final distribution on each Certificate (determined, in the case of
a Sequential Pay Certificate, without regard to any possible future
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to such Certificate, but taking into account possible future
distributions of Additional Interest) will be made in a like manner, but only
upon presentation and surrender of such Certificate at the offices of the
Certificate Registrar or such other location specified in the notice to
Certificateholders of such final distribution. Prior to any termination of the
Trust Fund pursuant to Section 9.01, any distribution that is to be made with
respect to a Certificate in reimbursement of a Realized Loss or Additional Trust
Fund Expense previously allocated thereto, which reimbursement is to occur after
the date on which such Certificate is surrendered as contemplated by the
preceding sentence, will be made by check mailed to the address of the
Certificateholder that surrendered such Certificate as such address last
appeared in the Certificate Register or to any other address of which the Paying
Agent was subsequently notified in writing. If such check is returned to the
Paying Agent, the Paying Agent, directly or through an agent, shall take such
reasonable steps to contact the related Holder and deliver such check as it
shall deem appropriate. Any funds in respect of a check returned to the Paying
Agent shall be set aside by the Paying Agent and held uninvested in trust and
credited to the account of the appropriate Holder. The costs and expenses of
locating the appropriate Holder and holding such funds shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust hereunder. If the Paying Agent has not, after having taken such
reasonable steps, located the related Holder by the second anniversary of the
initial sending of a check, the Paying Agent shall, subject to applicable law,
distribute the unclaimed funds to the Holders of the Class R-II Certificates.

            (d) Each distribution with respect to a Book-Entry Certificate shall
be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the related Certificate Owners that it represents and to each indirect
participating brokerage firm (a "brokerage firm" or "indirect participating
firm") for which it acts as agent. Each brokerage firm shall be responsible for
disbursing funds to the related Certificate Owners that it represents. None of
the Trustee, the Paying Agent, the Certificate Registrar, the Depositor or the
Master Servicer shall have any responsibility therefor except as otherwise
provided by this Agreement or applicable law. The Trustee and the Depositor
shall perform their respective obligations under a Letter of Representations
among the Depositor, the Trustee and the Initial Depository dated as of the
Closing Date.

            (e) The rights of the Certificateholders to receive distributions
from the proceeds of the Trust Fund in respect of the Certificates, and all
rights and interests of the Certificateholders in and to such distributions,
shall be as set forth in this Agreement. Neither the Holders of any Class of
Certificates nor any party hereto shall in any way be responsible or liable to
the Holders of any other Class of Certificates in respect of amounts properly
previously distributed on the Certificates.

            (f) Except as otherwise provided in Section 9.01, whenever the
Paying Agent receives written notification of or expects that the final
distribution with respect to any Class of Certificates (determined without
regard to any possible future reimbursement of any Realized Loss or Additional
Trust Fund Expense previously allocated to such Class of Certificates) will be
made on the next Distribution Date, the Paying Agent shall, no later than five
days after the related Determination Date, mail to each Holder of record on such
date of such Class of Certificates a notice to the effect that:

            (i) the Paying Agent expects that the final distribution with
      respect to such Class of Certificates will be made on such Distribution
      Date but only upon presentation and surrender of such Certificates at the
      office of the Certificate Registrar or at such other location therein
      specified, and

            (ii) no interest shall accrue on such Certificates from and after
      such Distribution Date.

            Any funds not distributed to any Holder or Holders of Certificates
of such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held
uninvested in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 4.01(f) shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Paying Agent shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been surrendered for
cancellation, the Paying Agent, directly or through an agent, shall take such
steps to contact the remaining non-tendering Certificateholders concerning the
surrender of their Certificates as it shall deem appropriate. The costs and
expenses of holding such funds in trust and of contacting such
Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust pursuant to this paragraph. If all of the Certificates shall not
have been surrendered for cancellation by the second anniversary of the delivery
of the second notice, the Paying Agent shall, subject to applicable law,
distribute to the Holders of the Class R-II Certificates all unclaimed funds and
other assets which remain subject thereto.

            (g) Notwithstanding any other provision of this Agreement, the
Paying Agent shall comply with all federal withholding requirements respecting
payments to Certificateholders of interest or original issue discount that the
Paying Agent reasonably believes are applicable under the Code. The Certificate
Registrar shall promptly provide the Paying Agent with any IRS Forms W-9,
W-8BEN, W-8IMY (and all appropriate attachments) or W-8ECI upon its receipt
thereof. The consent of Certificateholders shall not be required for such
withholding. If the Paying Agent does withhold any amount from interest or
original issue discount payments or advances thereof to any Certificateholder
pursuant to federal withholding requirements, the Paying Agent shall indicate
the amount withheld to such Certificateholders. Such amounts shall be deemed to
have been distributed to such Certificateholders for all purposes of this
Agreement.

            (h) All distributions made in respect of any Class of Sequential Pay
Certificates (other than the Class A-3SF Certificates and the Class A-MFL
Certificates), the Class A-3SF Regular Interest or the Class A-MFL Regular
Interest on each Distribution Date pursuant to Section 4.01(a) or Section 9.01
shall be deemed to have first been distributed, with respect to the Sequential
Pay Certificates (other than the Class A-3SF Certificates and the Class A-MFL
Certificates), the Class A-3SF Regular Interest and the Class A-MFL Regular
Interest from REMIC I to REMIC II in respect of its Corresponding REMIC I
Regular Interest set forth in the Preliminary Statement hereto; provided that
interest shall be deemed to have been distributed pro rata among two or more
Corresponding REMIC I Regular Interests that correspond to a Class of Sequential
Pay Certificates, and all distributions made in respect of the Class X-C and
Class X-P Certificates on each Distribution Date pursuant to Section 4.01(a) or
Section 9.01, and allocable to any particular Component of such Class of
Certificates in accordance with the last paragraph of Section 4.01(a), shall be
deemed to have been first distributed from REMIC I to REMIC II in respect of
such Component's Corresponding REMIC I Regular Interest; and provided, further,
that distributions of principal:

                        (1) with respect to the Class A-1 Certificates, shall be
                  deemed to have first been distributed from REMIC I to REMIC II
                  in respect of REMIC I Regular Interest LA-1-1; second, to
                  REMIC I Regular Interest LA-1-2; third, to REMIC I Regular
                  Interest LA-1-3; and fourth, to REMIC I Regular Interest
                  LA-1-4; in each case until their respective REMIC I Principal
                  Balances are reduced to zero;

                        (2) with respect to the Class A-2 Certificates, shall be

                  in respect of REMIC I Regular Interest LA-2-1; second, to
                  REMIC I Regular Interest LA-2-2; and third, to REMIC I Regular

                  II in respect of REMIC I Regular Interest LA-3SF-1; second, to

                  each case, until their respective REMIC I Principal Balances
                  are reduced to zero;

                        (4) with respect to the Class A-6A Certificates, shall
                  be deemed to have first been distributed from REMIC I to REMIC
                  II in respect of REMIC I Regular Interest LA-6A-1; and second,
                  to REMIC I Regular Interest LA-6A-2; in each case, until their

                  II in respect of REMIC I Regular Interest LA-6B-1; and second,
                  to REMIC I Regular Interest LA-6B-2; in each case, until their
                  respective REMIC I Principal Balances are reduced to zero;

                        (6) with respect to the Class A-PB Certificates, shall
                  be deemed to have first been distributed from REMIC I to REMIC
                  II in respect of REMIC I Regular Interest LA-PB-1; second, to

provided, however, all distributions made in respect of the Class X-C and Class

Section 9.01, and allocable to any particular Component of a Class of Sequential
Pay Certificates (other than the Class A-3SF Certificates or the Class A-MFL
Certificates), the Class A-3SF Regular Interest and the Class A-MFL Regular
Interest in accordance with the last paragraph of Section 4.01(a) shall be
deemed to have first been distributed from REMIC I to REMIC II in respect of
such Component's Corresponding REMIC I Regular Interest.

            (i) All distributions of reimbursements of Realized Losses and
Additional Trust Fund Expenses made in respect of any Class of Sequential Pay
Certificates (other than the A-3SF Certificates and the Class A-MFL
Certificates), the Class A-3SF Regular Interest and the Class A-MFL Regular
Interest on each Distribution Date pursuant to Section 4.01(a) shall be deemed
to have first been distributed from REMIC I to REMIC II in respect of its
Corresponding REMIC I Regular Interest set forth in the Preliminary Statement
hereto; provided, however, that distributions of reimbursements of Realized
Losses and Additional Trust Fund Expenses shall be made in sequential order of
the priority set forth in Section 4.01(h) for principal distributions, up to the
amount of Realized Losses and Additional Trust Fund Expenses previously
allocated to a particular Component of such Class of Certificates or the Class
A-3SF Regular Interest or the Class A-MFL Regular Interest. Any amounts
remaining in REMIC I on any Distribution Date after the foregoing distributions
shall be distributed to the Holders of the Class R-I Certificates.

            (j) On each Distribution Date, to the extent of the Class A-3SF
Available Funds for such Distribution Date, the Paying Agent shall make
distributions from the Class A-3SF Floating Rate Account in the following order
of priority, satisfying in full, to the extent required and possible, each
priority before making any distribution with respect to any succeeding priority:

                  (A) First, to the Holders of the Class A-3SF Certificates, in
            respect of interest, up to an amount equal to the Class A-3SF
            Interest Distribution Amount for such Distribution Date;

                  (B) Second, to the Holders of the Class A-3SF Certificates, in
            reduction of the Certificate Balances thereof, an amount equal to
            the Class A-3SF Principal Distribution Amount, until the outstanding
            Certificate Balance thereof has been reduced to zero;

                  (C) Third, to the Holders of the Class A-3SF Certificates,
            until all Realized Losses and Additional Trust Fund Expenses
            previously allocated to the Class A-3SF Certificates (as a result of
            the allocation of Realized Losses and Additional Trust Fund Expenses
            to the Class A-3SF Regular Interest) but not previously reimbursed,
            have been reimbursed in full;

                  (D) Fourth, to pay termination payments, if any, to the
            applicable Swap Counterparty; and

                  (E) Fifth, any remaining amount to the Holders of the Class
            A-3SF Certificates.

            (ii) So long as a Class A-3SF Distribution Conversion is not in
      effect, any Additional Yield Amounts paid on the Class A-3SF Regular
      Interest shall be payable to the Class A-3SF Swap Counterparty pursuant to
      the terms of the Class A-3SF Swap Contract, on a net basis as part of the
      Class A-3SF Net Swap Payment specified in Section 3.28. On each
      Distribution Date for which a Class A-3SF Distribution Conversion is in
      effect, any Additional Yield Amount paid on the Class A-3SF Regular
      Interest, shall be distributed to the Holders of the Class A-3SF
      Certificates.

            (iii) Any termination payments due to the Class A-3SF Swap
      Counterparty under the Class A-3SF Swap Contract shall be payable solely
      from (1) amounts, if any, remaining in the Class a-3SF Floating Rate
      Account after all other amounts have been paid to the Class A-3SF Regular
      Interest (including all principal amounts outstanding) and to the Class
      A-3SF Certificates pursuant to Section 4.01(j)(i)(A)-(C) and (2) to the
      extent of any payment made by a replacement swap counterparty to the Trust
      Fund in consideration for entering into such replacement swap contract, if
      any (less any costs and expenses incurred by the Trust Fund in connection
      with entering into such replacement swap contract).

            (k) On each Distribution Date, to the extent of the Class A-MFL
Available Funds for such Distribution Date, the Paying Agent shall make
distributions from the Class A-MFL Floating Rate Account in the following order
of priority, satisfying in full, to the extent required and possible, each
priority before making any distribution with respect to any succeeding priority:

                  (A) First, to the Holders of the Class A-MFL Certificates, in
            respect of interest, up to an amount equal to the Class A-MFL
            Interest Distribution Amount, respectively, for such Distribution
            Date;

                  (B) Second, to the Holders of the Class A-MFL Certificates, in
            reduction of the Certificate Balances thereof, an amount equal to
            the Class A-MFL Principal Distribution Amount, until the outstanding
            Certificate Balance thereof has been reduced to zero;

                  (C) Third, to the Holders of the Class A-MFL Certificates,
            until all Realized Losses and Additional Trust Fund Expenses
            previously allocated to the Class A-MFL Certificates (as a result of
            the allocation of Realized Losses and Additional Trust Fund Expenses
            to the Class A-MFL Regular Interest) but not previously reimbursed,
            have been reimbursed in full;

                  (D) Fourth, to pay termination payments, if any, to the
            applicable Swap Counterparty; and

                  (E) Fifth, any remaining amount to the Holders of the Class
            A-MFL Certificates, as the case may be.

            (ii) So long as a Class A-MFL Distribution Conversion is not in
      effect, any Additional Yield Amounts paid on the Class A-MFL Regular
      Interest shall be payable to the Class A-MFL Swap Counterparty, pursuant
      to the terms of the Class A-MFL Swap Contract, as applicable, on a net
      basis as part of the Class A-MFL Net Swap Payment specified in Section
      3.29. On each Distribution Date for which a Class A-MFL Distribution
      Conversion is in effect, any Additional Yield Amount paid on the Class
      A-MFL Regular Interest, as the case may be, shall be distributed to the
      Holders of the Class A-MFL Certificates, respectively.

            (iii) Any termination payments due to the Class A-MFL Swap
      Counterparty under the Class A-MFL Swap Contract shall be payable solely
      from (1) amounts, if any, remaining in the Class A-MFL Floating Rate
      Account after all other amounts have been paid to the Class A-MFL Regular
      Interest (including all principal amounts outstanding) and to the Class
      A-MFL Certificates, respectively, pursuant to Section 4.01(k)(i)(A)-(C)
      and (2) to the extent of any payment made by a replacement swap
      counterparty to the Trust Fund in consideration for entering into such
      replacement swap contract, if any (less any costs and expenses incurred by
      the Trust Fund in connection with entering into such replacement swap
      contract).

            (l) On each Distribution Date, or with respect to a Companion Loan
(other than the Non-Serviced Companion Loans) then included in a securitization,
on each P&I Advance Date, the Companion Paying Agent (based upon a statement of
the Master Servicer to be delivered to the Companion Paying Agent that specifies
the amount required to be deposited in the Companion Distribution Account and
any amounts payable to the Master Servicer from the Companion Distribution
Account pursuant to this Section 4.01(l)) shall make withdrawals and payments
from the Companion Distribution Account for the related Companion Loans in the
following order of priority:

            (i) to pay the Trustee or the Fiscal Agent or any directors,
      officers, employees and agents of either, as the case may be, any amounts
      payable or reimbursable to any such Person pursuant to Section 8.05 or
      Section 8.19, as applicable, to the extent any such amounts relate solely
      to a Loan Pair;

            (ii) to pay for the cost of the Opinions of Counsel sought by the
      Trustee as contemplated by Sections 9.02(a) and 10.01(h), to the extent
      any such costs relate to a Loan Pair;

            (iii) to pay to the Master Servicer any amounts deposited by the
      Master Servicer in the Companion Distribution Account not required to be
      deposited therein;

            (iv) on each Distribution Date (or such earlier date with respect to
      the NGP Rubicon GSA Pool Pari Passu Companion Loan and the Westfield San
      Francisco Centre Pari Passu Companion Loan on which funds are delivered to
      the Companion Paying Agent, as set forth in Section 3.04(b)) to pay all
      amounts remaining in the Companion Distribution Account to the Companion
      Holder; and

            (v) to clear and terminate the Companion Distribution Account at the
      termination of this Agreement pursuant to Section 9.01.

            All distributions from a Companion Distribution Account required
hereunder shall be made by the Companion Paying Agent to the Companion Holder by
wire transfer in immediately available funds to the account of such Companion
Holder or an agent therefor appearing on the Companion Register on the related
Record Date (or, if no such account so appears or information relating thereto
is not provided at least five Business Days prior to the related Record Date, by
check sent by first-class mail to the address of such Companion Holder or its
agent appearing on the Companion Register). Any such account shall be located at
a commercial bank in the United States. For the avoidance of doubt, in no event
shall the Companion Paying Agent withdraw from funds on deposit in the Companion
Distribution Account any amounts allocable to a Serviced Pari Passu Companion
Loan (other than Penalty Interest and late payment charges) to be applied to, or
to provide reimbursement for, any costs, expenses, indemnities, losses or
liabilities relating or allocable to any Mortgage Loan or Companion Loan other
than such Serviced Pari Passu Companion Loan or the related Serviced Pari Passu
Mortgage Loan.

            To the extent amounts are payable to or in respect of the Trust Fund
pursuant to this Section 4.01(l)(i) or (ii), the Companion Distribution Account
shall be considered an "outside reserve fund" within the meaning of the REMIC
Provisions, beneficially owned by the Companion Holder for federal income tax
purposes, who shall be taxable on all reinvestment income thereon, and who shall
be deemed to have received any amounts reimbursed from the Trust Fund to the
Companion Distribution Account.

            (m) On each Distribution Date, the Paying Agent shall withdraw
amounts from the Gain-on-Sale Reserve Account and shall distribute such amounts
to reimburse the Holders of each Class of Sequential Pay Certificates (other
than the Class A-3SF Certificates and the Class A-MFL Certificates), the Class
A-3SF Regular Interest and the Class A-MFL Regular Interest (in order of
priority) up to an amount equal to all Realized Losses and Additional Trust Fund
Expenses, if any, previously deemed allocated to such Classes and unreimbursed
after application of the Available Distribution Amount for such Distribution
Date. Amounts paid from the Gain-on-Sale Reserve Account pursuant to the
preceding sentence shall first be deemed to have been distributed to the
Corresponding REMIC I Regular Interest(s) in reimbursement of Realized Losses
and Additional Trust Fund Expenses previously allocated thereto as provided in
Section 4.01(i). Amounts paid from the Gain-on-Sale Reserve Account will not
reduce the Certificate Principal Balances of the Classes of Sequential Pay
Certificates (other than the Class A-3SF Certificates and the Class A-MFL
Certificates), the Class A-3SF Regular Interest or the Class A-MFL Regular
Interest receiving such distributions. Any amounts remaining in the Gain-on-Sale
Reserve Account after such distributions shall be applied to offset future
Realized Losses and Additional Trust Fund Expenses and upon termination of the
Trust Fund, any amounts remaining in the Gain-on-Sale Reserve Account shall be
distributed to the Class R-I Certificateholders.

control of the Special Servicer, the Trustee and the Master Servicer may, absent

            The Trustee may rely on and shall not be responsible absent manifest
error for the content or accuracy of any information provided by third parties

            Absent manifest error, none of the Master Servicer or the Special

2005-C19 Trustee, the LB-UBS 2005-C3 Master Servicer, the LB-UBS 2005-C3 Special

prepared or provided by the Master Servicer or the Special Servicer, as
applicable. The Trustee shall not be responsible absent manifest error for the
accuracy or completeness of any information supplied to it for delivery pursuant
to this Section 4.02(a). Neither the Trustee, the Master Servicer nor the
Special Servicer shall have any obligation to verify the accuracy or

            Within a reasonable period of time after the end of each calendar
year, the Trustee shall, upon request, send to each Person who at any time

pursuant to clauses (i), (ii), (iii) and (iv) of the description of
"Distribution Date Statement" above and such other information as may be
required to enable such Certificateholders to prepare their federal income tax
returns. Such information shall include the amount of original issue discount
accrued on each Class of Certificates and information regarding the expenses of
the Trust Fund. Such requirement shall be deemed to be satisfied to the extent
such information is provided pursuant to applicable requirements of the Code
from time to time in force.

any of its Depository Participants any of the statements, reports and/or other
written information described above in this Section 4.02(a) that it would
otherwise be entitled to receive if it were the Holder of a Definitive
Certificate evidencing its ownership interest in the related Class of Book Entry

electronically or cause the provision electronically of, such statements,
reports and/or other written information to such Certificate Owner upon the
request of such Certificate Owner made in writing to the Corporate Trust Office
(accompanied by current verification of such Certificate Owner's ownership
interest). Such portion of such information as may be agreed upon by the
Depositor and the Trustee shall be furnished to any such Person via overnight
courier delivery or telecopy from the Trustee; provided that the cost of such
overnight courier delivery or telecopy shall be an expense of the party
requesting such information.

            The Trustee shall only be obligated to deliver the statements,
reports and information contemplated by this Section 4.02(a) to the extent it
receives the necessary underlying information from the Special Servicer or
Master Servicer, as applicable, and shall not be liable for any failure to
deliver any thereof on the prescribed due dates, to the extent caused by failure
to receive timely such underlying information. Nothing herein shall obligate the
Trustee or the Master Servicer to violate any applicable law prohibiting
disclosure of information with respect to any Mortgagor and the failure of the
Trustee, Master Servicer or the Special Servicer to disseminate information for
such reason shall not be a breach hereof.

            (b) Not later than 1:00 p.m. New York City time on the second
Business Day preceding each Distribution Date the Master Servicer shall furnish
to the Trustee, the Depositor, the Special Servicer and the Underwriters, by

copy (other than in the case of the Trustee) of such transmitted information to
follow promptly, an accurate and complete CMSA Loan Periodic Update File

Agent) may conclusively rely on reports provided to it by the Master Servicer,
and the Trustee shall not be responsible to recompute, recalculate or verify the
information provided to it by the Master Servicer. In the case of information to
be furnished by the Master Servicer to the Trustee pursuant to this Section
4.02(b), insofar as such information is solely within the control of the Special
Servicer, the 2005-C19 Master Servicer, the 2005-C19 Special Servicer, the
2005-C19 Trustee, the LB-UBS 2005-C3 Master Servicer, the LB-UBS 2005-C3 Special
Servicer, the LB-UBS 2005-C3 Trustee, the MSCI 2005-HQ6 Master Servicer, the
MSCI 2005-HQ6 Special Servicer or the MSCI 2005-HQ6 Trustee, as the case may be,
the Master Servicer shall have no obligation to provide such information until
it has received such information from such party, shall not be in default
hereunder due to a delay in providing the CMSA Loan Periodic Update File caused
by the such party's failure to timely provide any report required under this
Agreement and may, absent manifest error, conclusively rely on the reports to be
provided by the such party.

            Section 4.03 P&I Advances.

            (a) On or before 1:30 p.m., New York City time, on each P&I Advance
Date, the Master Servicer shall (i) apply amounts in the Certificate Account
received after the end of the related Collection Period or otherwise held for
future distribution to Certificateholders in subsequent months in discharge of
its obligation to make P&I Advances or (ii) subject to Section 4.03(c) below,
remit from its own funds to the Paying Agent for deposit into the Distribution
Account, an amount equal to the aggregate amount of P&I Advances, if any, to be
made in respect of the related Distribution Date. The Master Servicer may also
make P&I Advances in the form of any combination of clauses (i) and (ii) above
aggregating the total amount of P&I Advances to be made. Any amounts held in the
Certificate Account for future distribution and so used to make P&I Advances
shall be appropriately reflected in the Master Servicer's records and replaced
by the Master Servicer by deposit in the Certificate Account on or before the
next succeeding Determination Date (to the extent not previously replaced
through the deposit of Late Collections of the delinquent principal and interest
in respect of which such P&I Advances were made). If, as of 3:00 p.m., New York
City time, on any P&I Advance Date, the Master Servicer shall not have made any
P&I Advance required to be made on such date pursuant to this Section 4.03(a)
(and shall not have delivered to the Trustee the requisite Officer's Certificate
and documentation related to a determination of nonrecoverability of a P&I
Advance), then the Trustee shall provide notice of such failure to a Servicing
Officer of the Master Servicer by facsimile transmission sent to telecopy (704)
715-0036 (or such alternative number provided by the Master Servicer to the
Trustee in writing) and by telephone at (704) 593-7836 or (704) 593-7867 (or
such alternative number provided by the Master Servicer to the Trustee in
writing) as soon as possible, but in any event before 4:00 p.m., New York City
time, on such P&I Advance Date. If the Trustee does not receive the full amount
of such P&I Advances by 10:00 a.m., New York City time, on the related
Distribution Date, then, subject to Section 4.03(c), (i) the Trustee or the
Fiscal Agent shall, no later than 11:00 a.m., New York City time, on such
related Distribution Date make the portion of such P&I Advances that was
required to be, but was not, made by the Master Servicer on such P&I Advance
Date, and (ii) the provisions of Sections 7.01 and 7.02 shall apply. If the
Trustee fails to make any such P&I Advance on the related Distribution Date, but
the Fiscal Agent makes such P&I Advance on such date, then such failure of the
Trustee shall be deemed to be cured.

            (b) The aggregate amount of P&I Advances to be made by the Master
Servicer, the Trustee or the Fiscal Agent in respect of any Distribution Date
shall, subject to Section 4.03(c) and Section 4.03(e) below, equal the aggregate
of all Periodic Payments (other than Balloon Payments) and any Assumed Scheduled
Payments, net of related Servicing Fees (and, in the case of the AmericasMart
Loan, the 101 Avenue of the Americas Loan and the U-Haul Portfolio Loan,
servicing fees due to the 2005-C19 Master Servicer, the LB-UBS 2005-C3 Master
Servicer or the MSCI 2005-HQ6 Master Servicer, as the case may be, to the extent
not so otherwise paid pursuant to the related Intercreditor Agreement) due or
deemed due, as the case may be, in respect of the Mortgage Loans (including,
without limitation, Balloon Mortgage Loans delinquent as to their respective
Balloon Payments) and any REO Loans on their respective Due Dates during (or
deemed to be during) the related Collection Period (i) in each case other than
with respect to the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced
Mortgage Loan or the MSCI 2005-HQ6 Serviced Mortgage Loan, to the extent such
amount was not paid by or on behalf of the related Mortgagor or otherwise
collected (including as net income from REO Properties) as of the close of
business on the last day of related Collection Period or (ii) in the case of the
2005-C19 Serviced Mortgage Loan, to the extent such amount was required to be
advanced by the 2005-C19 Master Servicer pursuant to the 2005-C19 Pooling and
Servicing Agreement, and the 2005-C19 Master Servicer failed to make such
advance, the Master Servicer shall be required to make such P&I Advance only to
the extent that Master Servicer has received all information necessary to
determine whether such P&I Advance is a Nonrecoverable Advance; provided that,
(x) if the Periodic Payment on any Mortgage Loan has been reduced in connection
with a bankruptcy or similar proceeding involving the related Mortgagor or a
modification, waiver or amendment granted or agreed to by the Special Servicer
pursuant to Section 3.20, or if the final maturity on any Mortgage Loan shall be
extended in connection with a bankruptcy or similar proceeding involving the
related Mortgagor or a modification, waiver or amendment granted or agreed to by
the Special Servicer pursuant to Section 3.20, and the Periodic Payment due and
owing during the extension period is less than the related Assumed Scheduled
Payment, then the Master Servicer, the Trustee or the Fiscal Agent shall, as to
such Mortgage Loan only, advance only the amount of the Periodic Payment due and
owing after taking into account such reduction (net of related Servicing Fees)
in the event of subsequent delinquencies thereon; and (y) if it is determined
that an Appraisal Reduction Amount exists with respect to any Required Appraisal
Mortgage Loan, then, with respect to the Distribution Date immediately following
the date of such determination and with respect to each subsequent Distribution
Date for so long as such Appraisal Reduction Amount exists with respect to such
Required Appraisal Mortgage Loan, the Master Servicer, the Trustee or the Fiscal
Agent will be required in the event of subsequent delinquencies to advance in
respect of such Mortgage Loan only an amount equal to the sum of (A) the amount
of the interest portion of the P&I Advance that would otherwise be required
without regard to this clause (y), minus the product of (1) such Appraisal
Reduction Amount and (2) the per annum Pass-Through Rate (i.e., for any month,
one-twelfth of the Pass-Through Rate) applicable to the Class of Certificates to
which such Appraisal Reduction Amount is allocated pursuant to Section 4.04(d)
and (B) the amount of the principal portion of the P&I Advance that would
otherwise be required without regard to this clause (y).

            (c) Notwithstanding anything herein to the contrary, no P&I Advance
shall be required to be made hereunder if such P&I Advance would, if made,
constitute a Nonrecoverable P&I Advance. The determination by the Master
Servicer or the Special Servicer that the Master Servicer has made a
Nonrecoverable P&I Advance or that any proposed P&I Advance, if made, would
constitute a Nonrecoverable P&I Advance, shall be evidenced by an Officer's
Certificate delivered to the Trustee, the Fiscal Agent and the Depositor on or
before the related P&I Advance Date, setting forth the basis for such
determination, together with any other information, including Appraisals (the
cost of which may be paid out of the Certificate Account pursuant to Section
3.05(a)) (or, if no such Appraisal has been performed pursuant to this Section
4.03(c), a copy of an Appraisal of the related Mortgaged Property performed
within the twelve months preceding such determination), related Mortgagor
operating statements and financial statements, budgets and rent rolls of the
related Mortgaged Properties, engineers' reports, environmental surveys and any
similar reports that the Master Servicer may have obtained consistent with the
Servicing Standard and at the expense of the Trust Fund, that support such
determination by the Master Servicer or the Special Servicer. As soon as
reasonably practical after making such determination, the Special Servicer shall
report to the Master Servicer the Special Servicer's determination as to whether
each P&I Advance made with respect to any previous Distribution Date or required
to be made with respect to such Distribution Date with respect to any Specially
Serviced Mortgage Loan or REO Loan is a Nonrecoverable P&I Advance. The Master
Servicer shall be entitled to conclusively rely on such determination by the
Special Servicer. The Trustee and the Fiscal Agent shall be entitled to rely,
conclusively, on any determination by the Master Servicer or the Special
Servicer that a P&I Advance, if made, would be a Nonrecoverable Advance (and
with respect to a P&I Advance, the Trustee or the Fiscal Agent, as applicable,
shall rely on the Master Servicer's determination that the P&I Advance would be
a Nonrecoverable Advance if the Trustee or the Fiscal Agent determines that it
does not have sufficient time to make such determination); provided, however,
that, if the Master Servicer has failed to make a P&I Advance for reasons other
than a determination by the Master Servicer or the Special Servicer that such
P&I Advance would be Nonrecoverable Advance, the Trustee shall make such Advance
within the time periods required by Section 4.03(a) unless the Trustee, in
accordance with the standard of care set forth in Section 8.01(a), makes a
determination prior to the times specified in Section 4.03(a) that such P&I
Advance would be a Nonrecoverable Advance; provided, further, however, if the
Trustee fails to make such Servicing Advance for reasons other than a
determination by the Trustee that such Servicing Advance would be a
Nonrecoverable Advance, the Fiscal Agent shall make such Servicing Advance
within the time periods required by Section 4.03(a) unless the Fiscal Agent in
good faith, makes a determination that such P&I Advance would be a
Nonrecoverable Advance. The Trustee, in determining whether or not a P&I Advance
previously made is, or a proposed P&I Advance, if made, would be, a
Nonrecoverable Advance shall be subject to the standards set forth in Section
8.01(a) hereunder, including utilizing its good faith business judgment to make
such determination.

            (d) In connection with the recovery by the Master Servicer, the
Trustee or the Fiscal Agent of any P&I Advance out of the Certificate Account
pursuant to Section 3.05(a), subject to the next sentence, the Master Servicer
shall be entitled to pay itself, the Trustee or the Fiscal Agent, as the case
may be, out of any amounts then on deposit in the Certificate Account, interest
at the Reimbursement Rate in effect from time to time, compounded annually,
accrued on the amount of such P&I Advance (to the extent made with its own
funds) from the date made (provided, however, no such interest shall accrue
during any grace period under a Mortgage Loan) to but not including the date of
reimbursement such interest to be payable, subject to the terms of the
Intercreditor Agreement with respect to the related Loan Pair, first out of late
payment charges and Penalty Interest received on the related Mortgage Loan or
REO Property during the Collection Period in which such reimbursement is made
and then from general collections on the Mortgage Loans then on deposit in the
Certificate Account. The Master Servicer shall reimburse itself, the Trustee or
the Fiscal Agent, as applicable, for any outstanding P&I Advance made thereby as
soon as practicable after funds available for such purpose have been received by
the Master Servicer, and in no event shall interest accrue in accordance with
this Section 4.03(d) on any P&I Advance as to which the corresponding payment of
principal and interest or Late Collection was received by the Master Servicer on
or prior to the related P&I Advance Date.

            (e) In no event shall the Master Servicer make a P&I Advance with
respect to any Companion Loan other than as contemplated by Section 4.03(f). In
no event shall the Trustee or the Fiscal Agent make a P&I Advance with respect
to any Companion Loan.

            (f) Subject to Section 4.03(b) and Section 4.03(c), the Master
Servicer shall make P&I Advances in respect of the 1000 & 1100 Wilson Companion
Loan only during such time as the related Companion Loan is included in a
securitization or a collateralized debt obligation in which interests therein
are issued or created pursuant to the terms of the related Intercreditor
Agreement. With respect to any P&I Advance made on the 1000 & 1100 Wilson
Companion Loan, the Master Servicer shall be entitled to recovery of such
amounts from the holder thereof. For the avoidance of doubt, the Trust Fund
shall not be liable for any recoveries of P&I Advances made by the Master
Servicer on the related Companion Loan. Notwithstanding anything to the contrary
contained herein, neither the Trustee nor the Fiscal Agent shall have any
obligation hereunder to and shall not make P&I Advances in respect of the 1000 &
1100 Wilson Companion Loan.

            (g) None of the Master Servicer, the Paying Agent, the Trustee or
the Fiscal Agent shall advance any amount due to be paid by the Class A-3SF Swap
Counterparty or the Class A-MFL Swap Counterparty for distribution to the Class
A-3SF Certificates or the Class A-MFL Certificates, respectively.

            (h) With respect to the U-Haul Portfolio Whole Loan, if (1) the MSCI
2005-HQ6 Master Servicer has determined that a proposed P&I Advance (as defined
in the MSCI 2005-HQ6 Pooling and Servicing Agreement) with respect to the U-Haul
Portfolio Pari Passu Loan, if made, or any outstanding P&I Advance previously
made, would be, or is, as applicable, a "nonrecoverable advance," and the MSCI
2005-HQ6 Master Servicer has provided written notice of such determination to
the Master Servicer, or (2) if the Master Servicer or Special Servicer has
determined that a P&I Advance with respect to the U-Haul Portfolio Loan would be
or is a Nonrecoverable P&I Advance, then none of the Master Servicer, the
Trustee or the Fiscal Agent shall make any additional P&I Advance with respect
to the U-Haul Portfolio Loan until the Master Servicer has consulted with the
MSCI 2005-HQ6 Master Servicer and they agree that the circumstances with respect
to the U-Haul Portfolio Loan have changed such that a proposed future P&I
Advance would not be a "nonrecoverable advance." With respect to the U-Haul
Portfolio Loan, if the Master Servicer or Special Servicer has determined that a
proposed P&I Advance with respect to such loan, would be a Nonrecoverable
Advance, the Master Servicer shall provide the MSCI 2005-HQ6 Master Servicer
written notice of such determination within two Business Days after such
determination was made (or in the case of a determination by the Special
Servicer, within two days of the Special Servicer notifying the Master Servicer
of such determination).

            If the Master Servicer has received notice that the MSCI 2005-HQ6
Master Servicer is no longer approved by Moody's or Fitch or is no longer listed
on S&P's Select Servicer List as a U.S. Commercial Mortgage Master Servicer,
then the Master Servicer shall not be required to abide by any determination of
nonrecoverability by the MSCI 2005-HQ6 Master Servicer.

            (i) With respect to the NGP Rubicon GSA Pool Loan, the Master
Servicer will be required to make its determination that it has made a
Nonrecoverable P&I Advance with respect to such Mortgage Loan independently of
any determination made by the master servicer with respect to a commercial
mortgage securitization holding the NGP Rubicon GSA Pool Pari Passu Companion
Loan (although it is understood that the Master Servicer shall not be precluded
from considering any information that it would normally consider in making any
nonrecoverability determination). If the Master Servicer determines that a
proposed P&I Advance with respect to the NGP Rubicon GSA Pool Loan if made, or
any outstanding P&I Advance with respect to the NGP Rubicon GSA Pool Loan
previously made, would be, or is, as applicable, a Nonrecoverable Advance, the
Master Servicer will be required to promptly provide such master servicer with
respect to the NGP Rubicon GSA Pool Pari Passu Companion Loan written notice of
such determination.

            (j) With respect to the 101 Avenue of the Americas Loan, if the
Master Servicer determines that a proposed P&I Advance with respect to the 101
Avenue of the Americas Loan, if made, or any outstanding P&I Advance with
respect to such Mortgage Loan previously made, would be, or is, as applicable, a
Nonrecoverable P&I Advance, the Master Servicer will be required to provide the
LB-UBS 2005-C3 Master Servicer written notice of such determination. In
addition, if the LB-UBS 2005-C3 Master Servicer determines that any P&I Advance
made or to be made with respect to the 101 Avenue of the Americas Loan is or, if
made, would be a Nonrecoverable P&I Advance, then the LB-UBS 2005-C3 Master
Servicer will be required to notify the Master Servicer within one Business Day
of such determination, which notice will be accompanied by the supporting
evidence for such determination. Following a determination of nonrecoverability
by the Master Servicer or the LB-UBS 2005-C3 Master Servicer, the Master
Servicer and the LB-UBS 2005-C3 Master Servicer will be required to consult
regarding whether circumstances with respect to the 101 Avenue of the Americas
Whole Loan have changed such that a proposed future P&I Advance would not be a
Nonrecoverable P&I Advance.

            Section 4.04 Allocation of Realized Losses and Additional Trust Fund
Expenses; Allocation of Certificate Deferred Interest; Allocation of Appraisal
Reduction Amounts.

            (a) On each Distribution Date, following all distributions to be
made on such date pursuant to Section 4.01, the Paying Agent shall allocate to
the respective Classes of Sequential Pay Certificates (other than the Class
A-3SF Certificates and the Class A-MFL Certificates), the Class A-3SF Regular
Interest and the Class A-MFL Regular Interest the aggregate of all Realized
Losses and Additional Trust Fund Expenses that were incurred at any time
following the Cut-Off Date through the end of the related Collection Period and
in any event that were not previously allocated pursuant to this Section 4.04(a)
on any prior Distribution Date, but only to the extent that (i) the aggregate
Certificate Principal Balance of the Sequential Pay Certificates (other than the
Class A-3SF Certificates and the Class A-MFL Certificates), the Class A-3SF
Regular Interest and the Class A-MFL Regular Interest as of such Distribution
Date (after taking into account all of the distributions made on such
Distribution Date pursuant to Section 4.01), exceeds (ii) the aggregate Stated
Principal Balance of the Mortgage Pool that will be outstanding immediately
following such Distribution Date (for purposes of this calculation only, not
giving effect to any reductions of the Stated Principal Balance for payments of
principal collected on the Mortgage Loans that were used to reimburse any
Nonrecoverable Advances, to the extent a Final Recovery Determination has not
been made with respect thereto, and Workout-Delayed Reimbursement Amounts
pursuant to Section 3.05(a)(vii) hereof): first, to the Class P Certificates,
until the remaining Class Principal Balance thereof has been reduced to zero,
second, to the Class O Certificates, until the remaining Class Principal Balance
thereof has been reduced to zero, third, to the Class N Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; fourth, to
the Class M Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; fifth, to the Class L Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; sixth, to
the Class K Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; seventh, to the Class J Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; eighth, to
the Class H Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; ninth, to the Class G Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; tenth, to
the Class F Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; eleventh, to the Class E Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; twelfth, to
the Class D Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; thirteenth, to the Class C Certificates, until the
remaining Class Principal Balance thereof has been reduced to zero; fourteenth,
to the Class B Certificates, until the remaining Class Principal Balance thereof
has been reduced to zero; fifteenth to the Class A-J Certificates until the
remaining Class Principal Balance thereof has been reduced to zero; sixteenth to
the Class A-MFL Regular Interest (and therefore the Class A-MFL Certificates)
and the Class A-MFX Certificates, pro rata, until the remaining Class Principal
Balance thereof has been reduced to zero; and seventeenth, pro rata (based on
remaining Class Principal Balances) to the Class A-1 Certificates, the Class A-2
Certificates, the Class A-4 Certificates, the Class A-5 Certificates, the Class
A-6A Certificates, the Class A-6B Certificates, the Class A-PB Certificates, the
Class A-7 Certificates and the Class A-1A Certificates and the Class A-3SF
Regular Interest (and therefore the Class A-3SF Certificates), until the Class
Principal Balances thereof are reduced to zero. Any allocation of Realized
Losses and Additional Trust Fund Expenses to a Class of Regular Certificates,
the Class A-3SF Regular Interest and the Class A-MFL Regular Interest shall be
made by reducing the Class Principal Balances thereof by the amount so
allocated. All Realized Losses and Additional Trust Fund Expenses, if any,
allocated to the Class A-3SF Regular Interest and the Class A-MFL Regular
Interest shall result in a corresponding reduction of the Certificate Balances
of the Class A-3SF Certificates and the Class A-MFL Certificates, respectively.
All Realized Losses and Additional Trust Fund Expenses, if any, allocated to a
Class of Regular Certificates (or, with respect to the Class A-3SF Certificates
or the Class A-MFL Certificates, an amount corresponding to any Realized Losses
and Additional Trust Fund Expenses allocated to the Class A-3SF Regular Interest
and the Class A-MFL Regular Interest, respectively) shall be allocated among the
respective Certificates of such Class in proportion to the Percentage Interests
evidenced thereby. All Realized Losses and Additional Trust Fund Expenses, if
any, that have not been allocated to the Regular Certificates, the Class A-3SF
Regular Interest and the Class A-MFL Regular Interest as of the Distribution
Date on which the aggregate Certificate Principal Balance of such Regular
Certificates, the Class Principal Balance of the Class A-3SF Regular Interest
and the Principal Balance of the Class A-MFL Regular Interest have been reduced
to zero, shall be deemed allocated to the Residual Certificates.

            (b) On each Distribution Date, following the deemed distributions of
principal or reimbursement of previously allocated Realized Losses and
Additional Trust Fund Expenses made in respect of the REMIC I Regular Interests
pursuant to Section 4.01(h), the REMIC I Principal Balance (or aggregate REMIC I
Principal Balance with respect to the REMIC I Regular Interests corresponding to
the Class A-1, Class A-2, Class A-4, Class A-5, Class A-6A, Class A-6B, Class
A-PB, Class A-7, Class A-1A, Class D, Class E, Class F, Class G, and Class H
Certificates and the Class A-3SF Regular Interest) of the Corresponding REMIC I
Regular Interests (after taking account of such deemed distributions) shall be
reduced as a result of Realized Losses and Additional Trust Fund Expenses to
equal the Class Principal Balance of the Corresponding Certificates that will be
outstanding immediately following such Distribution Date; provided that Realized
Losses and Additional Trust Fund Expenses shall be allocated:

            (i) with respect to the Class A-1 Certificates, first, in respect of
      REMIC I Regular Interest LA-1-1; second, to REMIC I Regular Interest
      LA-1-2; third, to REMIC I Regular Interest LA-1-3; and fourth, to REMIC I

      of REMIC I Regular Interest LA-2-1; second, to REMIC I Regular Interest

      LA-3SF-5; in each case, until their respective REMIC I Principal Balances
      are reduced to zero;

            (iv) with respect to the Class A-6A Certificates, first, in respect
      of REMIC I Regular Interest LA-A-6A-1; and second, to REMIC I Regular
      Interest LA-6A-2; in each case, until their respective REMIC I Principal
      Balances are reduced to zero;

            (xiii) with respect to the Class G Certificates, first, in respect

            (c) On any Distribution Date, the amount of any Mortgage Deferred

Class of Sequential Pay Certificates (other than the Class A-3SF Certificates
and the Class A-MFL Certificates), the Class A-3SF Regular Interest and the
Class A-MFL Regular Interest in reverse order of priorities (except with respect
to the Class A-1, Class A-2, Class A-4, Class A-5, Class A-6A, Class A-6B, Class
A-PB, Class A-7 and Class A-1A Certificates and the Class A-3SF Regular
Interest, which amounts shall be applied pro rata (based on remaining Class
Principal Balances) to such Certificates and the Class A-3SF Regular Interest),
in each case up to the respective Accrued Certificate Interest for each such
Class of Certificates (other than the Class A-3SF Certificates and the Class
A-MFL Certificates), the Class A-3SF Regular Interest or the Class A-MFL Regular
Interest, as applicable, for such Distribution Date. On each such Distribution
Date, the Certificate Principal Balance of each Class of Certificates (other
than the Class A-3SF Certificates and the Class A-MFL Certificates), the Class
A-3SF Regular Interest or the Class A-MFL Regular Interest, as applicable, to
which Certificate Deferred Interest has been allocated shall be increased by the
amount of Certificate Deferred Interest allocated to such Class of Certificates,
the Class A-3SF Regular Interest or the Class A-MFL Regular Interest. All
Certificate Deferred Interest, if any, allocated to the Class A-3SF Regular
Interest or the Class A-MFL Regular Interest shall result in a corresponding
increase of the Certificate Balances of the Class A-3SF Certificates or the
Class A-MFL Certificates, respectively. Certificate Deferred Interest will be
allocated to the Class A-MFX Certificates and the Class A-MFL Regular Interest
on a pro rata basis (based on remaining Class Principal Balances). The amount of
Certificate Deferred Interest allocated to any Class of Sequential Pay
Certificates (other than the Class A-3SF Certificates and the Class A-MFL
Certificates), the Class A-3SF Regular Interest or the Class A-MFL Regular
Interest, as applicable, shall be allocated to, and will increase the REMIC I
Principal Balances of the Corresponding REMIC I Regular Interest(s) in reverse
order of priorities; provided, however, that with respect to the Class A-1,
Class A-2, Class A-4, Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7
and Class A-1A Certificates and the Class A-3SF Regular Interest, allocations to
the Corresponding REMIC I Regular Interests shall be made on a pro rata basis.

            (d) Any Appraisal Reduction Amounts shall be allocated only for
purposes of determining the amount of P&I Advances with respect to the related
Mortgage Loan, as follows: to the Class Principal Balance of the Class P, Class
O, Class N, Class M, Class L, Class K, Class J, Class H, Class G, Class F, Class
E, Class D, Class C, Class B, Class A-J, then Class A-MFX and Class A-MFL
Certificates, pro rata, in that order, up to the amount of their respective
Class Principal Balances, and then to the Class A Certificates on a pro rata
basis; provided, however, that with respect to any Appraisal Reduction Amount
relating to a Co-Lender Loan, such Appraisal Reduction Amount will be applied,
first to the Subordinate Companion Loans from the most junior to the most
senior, and then, will be applied pro rata to any Pari Passu Companion Loan and
its related Co-Lender Loan. On any Distribution Date, an Appraisal Reduction
Amount that otherwise would be allocated to a Class of Certificates shall be
allocated to the next most subordinate Class to the extent that the Class
Principal Balance on such Distribution Date for such Class of Certificates
(prior to taking the Appraisal Reduction Amount into account) is less than the
Appraisal Reduction Amount for the Distribution Date. The Master Servicer shall
report to the Trustee on or before each Determination Date all Appraisal
Reduction Amounts and the Trustee shall report to the Master Servicer no later
than 10:00 a.m. on the related P&I Advance Date the Pass-Through Rates necessary
to calculate the allocation required by this Section 4.04(d).

            Section 4.05 Calculations.

            The Paying Agent shall, provided it receives the necessary
information from the Master Servicer and the Special Servicer, be responsible
for performing all calculations necessary in connection with the actual and
deemed distributions and allocations to be made pursuant to Section 4.01,
Section 5.02(d) and Article IX and the actual and deemed allocations of Realized
Losses and Additional Trust Fund Expenses to be made pursuant to Section 4.04.
The Paying Agent shall calculate the Available Distribution Amount for each
Distribution Date and shall allocate such amount among Certificateholders in
accordance with this Agreement, and the Paying Agent shall have no obligation to
recompute, recalculate or verify any information provided to it by the Special
Servicer or Master Servicer. The calculations by the Paying Agent of such
amounts shall, in the absence of manifest error, be presumptively deemed to be
correct for all purposes hereunder.

            Section 4.06 Use of Agents.

            The Master Servicer, the Trustee or the Fiscal Agent may at its own
expense utilize agents or attorneys-in-fact in performing any of its obligations
under this Article IV (except the obligation to make P&I Advances), but no such
utilization shall relieve the Master Servicer, the Trustee or the Fiscal Agent
from any of such obligations or liabilities, and the Master Servicer, the
Trustee or the Fiscal Agent, as applicable, shall remain responsible for all
acts and omissions of any such agent or attorney-in-fact (other than with
respect to limited powers-of-attorney delivered by the Trustee to the Master
Servicer or Special Servicer pursuant to Section 2.03(b) and 3.01(b), as
applicable, in which case the Trustee shall have no such responsibility).

                                   ARTICLE V

                                THE CERTIFICATES

            Section 5.01 The Certificates.

            (a) The Certificates will be substantially in the respective forms
attached hereto as Exhibit A; provided that any of the Certificates may be
issued with appropriate insertions, omissions, substitutions and variations, and
may have imprinted or otherwise reproduced thereon such legend or legends, not
inconsistent with the provisions of this Agreement, as may be required to comply
with any law or with rules or regulations pursuant thereto, or with the rules of
any securities market in which the Certificates are admitted to trading, or to
conform to general usage. The Certificates will be issuable in registered form
only; provided, however, that in accordance with Section 5.03 beneficial
ownership interests in the Regular Certificates, the Class A-3SF Certificates
and the Class A-MFL Certificates shall initially be held and transferred through
the book-entry facilities of the Depository. The Regular Certificates, the Class
A-3SF Certificates and the Class A-MFL Certificates will be issuable only in
denominations corresponding to initial Certificate Principal Balances or initial
Certificate Notional Amounts, as the case may be, as of the Closing Date of not
less than $10,000 in the case of the Registered Certificates, $1,000,000 in the
case of the Class X Certificates, and $250,000 in the case of Non-Registered
Certificates (other than the Residual Certificates and the Class X
Certificates), and in each such case in integral multiples of $1 in excess
thereof. The Class Z Certificates, Class R-I Certificates and the Class R-II
Certificates shall have no minimum denomination and shall each be represented by
a single definitive certificate.

            (b) The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee by the Certificate Registrar hereunder by an
authorized signatory. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the authorized signatories of the Certificate
Registrar shall be entitled to all benefits under this Agreement, subject to the
following sentence, notwithstanding that such individuals or any of them have
ceased to hold such offices prior to the authentication and delivery of such
Certificates or did not hold such offices at the date of such Certificates. No
Certificate shall be entitled to any benefit under this Agreement, or be valid
for any purpose, however, unless there appears on such Certificate a certificate
of authentication substantially in the form provided for herein executed by the
Authenticating Agent by manual signature, and such certificate of authentication
upon any Certificate shall be conclusive evidence, and the only evidence, that
such Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

            Section 5.02 Registration of Transfer and Exchange of Certificates.

            (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar may
prescribe, the Certificate Registrar (located as of the Closing Date at the
Corporate Trust Office), shall provide for the registration of Certificates and
of transfers and exchanges of Certificates as herein provided. The Trustee is
hereby initially appointed (and hereby agrees to act in accordance with the
terms hereof) as Certificate Registrar for the purpose of registering
Certificates and transfers and exchanges of Certificates as herein provided. The
Certificate Registrar may appoint, by a written instrument delivered to the
Depositor, the Trustee, the Special Servicer and the Master Servicer, any other
bank or trust company to act as Certificate Registrar under such conditions as
the predecessor Certificate Registrar may prescribe; provided that the
predecessor Certificate Registrar shall not be relieved of any of its duties or
responsibilities hereunder by reason of such appointment. If the Trustee resigns
or is removed in accordance with the terms hereof, the successor trustee shall
immediately succeed to its duties as Certificate Registrar. The Depositor, the
Trustee (if it is no longer the Certificate Registrar), the Master Servicer and
the Special Servicer shall have the right to inspect the Certificate Register or
to obtain a copy thereof at all reasonable times, and to rely conclusively upon
a certificate of the Certificate Registrar as to the information set forth in
the Certificate Register. Upon written request of any Certificateholder made for
purposes of communicating with other Certificateholders with respect to their
rights under this Agreement, the Certificate Registrar shall promptly furnish
such Certificateholder with a list of the other Certificateholders of record
identified in the Certificate Register at the time of the request.

            (b) No transfer of any Non-Registered Certificate shall be made
unless that transfer is made pursuant to an effective registration statement
under the Securities Act, and effective registration or qualification under
applicable state securities laws, or is made in a transaction that does not
require such registration or qualification. If such a transfer is to be made
without registration under the Securities Act (other than in connection with the
initial issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective Affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives (and upon receipt, may
conclusively rely upon) either: (i) a certificate from the Certificateholder
desiring to effect such transfer substantially in the form attached as Exhibit
F-1 hereto, and a certificate from such Certificateholder's prospective
transferee substantially in the form attached as either Exhibit F-2 hereto or as
Exhibit F-3 hereto; or (ii) an Opinion of Counsel reasonably satisfactory to the
Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust Fund or of the Depositor, the Master Servicer, the Special
Servicer, the Trustee or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee or the
Certificate Registrar is obligated to register or qualify any Class of
Non-Registered Certificates under the Securities Act or any other securities law
or to take any action not otherwise required under this Agreement to permit the
transfer of any Non-Registered Certificate without registration or
qualification. Any Holder of a Non-Registered Certificate desiring to effect
such a transfer shall, and upon acquisition of such a Certificate shall be
deemed to have agreed to, indemnify the Trustee, the Certificate Registrar and
the Depositor against any liability that may result if the transfer is not so
exempt or is not made in accordance with such federal and state laws.

            In connection with transfer of the Non-Registered Certificates, the
Depositor shall furnish upon request of a Certificateholder or Certificate Owner
to such Holder or Certificate Owner and any prospective purchaser designated by
such Certificateholder or Certificate Owner the information required to be
delivered under paragraph (d)(4) of Rule 144A of the Securities Act.

            Notwithstanding the foregoing, for so long as any Non-Registered
Certificate is a Book-Entry Certificate, (a) each prospective transferor of such
Certificate shall be deemed to have represented to the Trustee, the Depositor
and the transferee of such Certificate the information set forth on Exhibit F-1
upon or prior to such transfer and (b) each prospective transferee of such
Certificate shall be deemed to have represented to the Trustee, the Depositor
and the transferor of such Certificate the information set forth on Exhibit F-2
or Exhibit F-3 upon or prior to such transfer. In addition, if such prospective
transferee is an Institutional Accredited Investor (but not also a Qualified
Institutional Buyer), such prospective transferee shall be deemed to have
acknowledged that any beneficial interest in a Book-Entry Certificate that is
transferred to it is required to be delivered in the form of a Definitive
Certificate and shall cease to be an interest in such Book-Entry Certificate
and, thereafter, shall be subject to all transfer restrictions and other
procedures applicable to Certificates in definitive form.

            (c) No transfer of a Certificate or any interest therein shall be
made to any "employee benefit plan" subject to Title I of ERISA, any "plan"
subject to Section 4975 of the Code or any other retirement plan or other
employee benefit plan or arrangement subject to applicable federal, state or
local law ("Similar Law") materially similar to the foregoing provisions of
ERISA or the Code, or any entity deemed to hold plan assets of the foregoing by
reason of such a plan's investment in such entity (each, a "Plan") unless (A) in
the case of a Certificate other than a Residual Certificate or a Class Z
Certificate, the transferee is an insurance company general account which is
eligible for, and satisfies all the requirements of, exemptive relief under
Sections I and III of Department of Labor Prohibited Transaction Class Exemption
95-60 ("PTE 95-60") or (B) in the case of a Certificate other than an ERISA
Restricted Certificate, a Residual Certificate or a Class Z Certificate, the
transferee (1) qualifies as an accredited investor as defined in Rule 501(a)(1)
of Regulation D under the Securities Act and (2) satisfies all the requirements
of the Exemptions as in effect at the time of such transfer. Each Person who
acquires a Certificate in Definitive Certificate form shall be required to
certify in writing in the form attached as Exhibit G hereto that it meets the
foregoing conditions and that it will not transfer such Certificate in violation
of the foregoing, and each Person who acquires a Certificate in Book-Entry
Certificate form shall be deemed to have represented that the foregoing
conditions are satisfied and that it will not transfer such Certificate in
violation of the foregoing.

            (d) (i) Each Person who has or who acquires any Ownership Interest
in a Residual Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the following provisions
and to have irrevocably authorized the Paying Agent under clause (ii)(A) below
to deliver payments to a Person other than such Person and to have irrevocably
authorized the Certificate Registrar under clause (ii)(B) below to negotiate the
terms of any mandatory disposition and to execute all instruments of Transfer
and to do all other things necessary in connection with any such sale. The
rights of each Person acquiring any Ownership Interest in a Residual Certificate
are expressly subject to the following provisions:

                  (A) Each Person holding or acquiring any Ownership Interest in
            a Residual Certificate shall be a Permitted Transferee and shall
            promptly notify the Master Servicer, the Paying Agent and the
            Certificate Registrar of any change or impending change in its
            status as a Permitted Transferee.

                  (B) In connection with any proposed Transfer of any Ownership
            Interest in a Residual Certificate, the Certificate Registrar shall
            require delivery to it, and shall not register the Transfer of any
            Residual Certificate until its receipt of an affidavit and agreement
            substantially in the form attached hereto as Exhibit H-1 (a
            "Transfer Affidavit and Agreement"), from the proposed Transferee,
            in form and substance satisfactory to the Certificate Registrar, and
            upon which the Certificate Registrar may, in the absence of actual
            knowledge by a Responsible Officer of either the Trustee or the
            Certificate Registrar to the contrary, conclusively rely,
            representing and warranting, among other things, that such
            Transferee is a Permitted Transferee; that it is not acquiring its
            Ownership Interest in the Residual Certificate that is the subject
            of the proposed Transfer as a nominee, trustee or agent for any
            Person that is not a Permitted Transferee; that for so long as it
            retains its Ownership Interest in a Residual Certificate, it will
            endeavor to remain a Permitted Transferee; that it has historically
            paid its debts as they have come due, intends to pay its debts as
            they come due in the future and intends to pay all taxes associated
            with the Residual Certificate as they come due; and that it has
            reviewed the provisions of this Section 5.02(d) and agrees to be
            bound by them.

                  (C) Notwithstanding the delivery of a Transfer Affidavit and
            Agreement by a proposed Transferee under clause (B) above, if a
            Responsible Officer of the Certificate Registrar has actual
            knowledge that the proposed Transferee is not a Permitted
            Transferee, no Transfer of an Ownership Interest in a Residual
            Certificate to such proposed Transferee shall be effected.

                  (D) Each Person holding or acquiring any Ownership Interest in
            a Residual Certificate shall agree (a) to require a Transfer
            Affidavit and Agreement from any prospective Transferee to whom such
            Person attempts to transfer its Ownership Interest in such Residual
            Certificate and (b) not to transfer its Ownership Interest in such
            Residual Certificate unless it provides to the Certificate Registrar
            a certificate substantially in the form attached hereto as Exhibit
            H-2 stating that, among other things, it has no actual knowledge
            that such prospective Transferee is not a Permitted Transferee.

                  (E) Each Person holding or acquiring an Ownership Interest in
            a Residual Certificate, by purchasing an Ownership Interest in such
            Certificate, agrees to give the Master Servicer and the Trustee
            written notice that it is a "pass-through interest holder" within
            the meaning of temporary Treasury regulation Section
            1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest
            in a Residual Certificate, if it is, or is holding an Ownership
            Interest in a Residual Certificate on behalf of, a "pass-through
            interest holder."

            (ii) (1) If any purported Transferee shall become a Holder of a
      Residual Certificate in violation of the provisions of this Section
      5.02(d), then the last preceding Holder of such Residual Certificate that
      was in compliance with the provisions of this Section 5.02(d) shall be
      restored, to the extent permitted by law, to all rights as Holder thereof
      retroactive to the date of registration of such Transfer of such Residual
      Certificate. None of the Trustee, the Master Servicer or the Certificate
      Registrar shall be under any liability to any Person for any registration
      of Transfer of a Residual Certificate that is in fact not permitted by
      this Section 5.02(d) or for making any payments due on such Certificate to
      the Holder thereof or for taking any other action with respect to such
      Holder under the provisions of this Agreement.

                        (2) If any purported Transferee shall become a Holder of
                  a Residual Certificate in violation of the restrictions in
                  this Section 5.02(d), then, to the extent that the retroactive
                  restoration of the rights of the preceding Holder of such
                  Residual Certificate as described in clause (ii)(A) above
                  shall be invalid, illegal or unenforceable, the Certificate
                  Registrar shall have the right, without notice to the Holder
                  or any prior Holder of such Residual Certificate, to cause the
                  transfer of such Residual Certificate to a Permitted
                  Transferee on such terms as the Certificate Registrar may
                  choose. Such purported Transferee shall promptly endorse and
                  deliver such Residual Certificate in accordance with the
                  instructions of the Certificate Registrar. Such Permitted
                  Transferee may be the Certificate Registrar itself or any
                  Affiliate of the Certificate Registrar. Any proceeds of such
                  sale, net of the commissions (which may include commissions
                  payable to the Certificate Registrar or its Affiliates),
                  expenses and taxes due, if any, will be remitted by the Paying
                  Agent to such purported Transferee. The terms and conditions
                  of any sale under this clause (ii)(B) shall be determined in
                  the sole discretion of the Certificate Registrar, and the
                  Certificate Registrar shall not be liable to any Person having
                  an Ownership Interest in a Residual Certificate as a result of
                  its exercise of such discretion.

            (iii) The Certificate Registrar shall make available to the Internal
      Revenue Service and to those Persons specified by the REMIC Provisions any
      information available to it which is necessary to compute any tax imposed
      as a result of the Transfer of an Ownership Interest in a Residual
      Certificate to any Person who is a Disqualified Organization or agent
      thereof, including the information described in Treasury Regulations
      Sections 1.860D-1(b)(5) and 1.860E-2(a)(5) with respect to the "excess
      inclusions" of such Residual Certificate, and the Master Servicer and the
      Special Servicer shall furnish to the Certificate Registrar all
      information in its possession necessary for the Certificate Registrar to
      discharge such obligation. The transferor of such Ownership Interest shall
      be responsible for the reasonable compensation of the Certificate
      Registrar, the Master Servicer and the Special Servicer for providing such
      information.

            (iv) The provisions of this Section 5.02(d) set forth prior to this
      clause (iv) may be modified, added to or eliminated; provided that there
      shall have been delivered to the Certificate Registrar and the Master
      Servicer the following:

                  (A) written confirmation from each Rating Agency to the effect
            that the modification of, addition to or elimination of such
            provisions will not cause such Rating Agency to qualify, downgrade
            or withdraw its then-current rating of any Class of Certificates;
            and

                  (B) an Opinion of Counsel, in form and substance satisfactory
            to the Certificate Registrar and the Master Servicer, obtained at
            the expense of the party seeking such modification of, addition to
            or elimination of such provisions (but in no event at the expense of
            the Trust Fund), to the effect that doing so will not cause either
            of REMIC I or REMIC II to (x) cease to qualify as a REMIC or (y) be
            subject to an entity-level tax caused by the Transfer of any
            Residual Certificate to a Person which is not a Permitted
            Transferee, or cause a Person other than the prospective Transferee
            to be subject to a REMIC-related tax caused by the Transfer of a
            Residual Certificate to a Person that is not a Permitted Transferee.

            (e) Subject to the preceding provisions of this Section 5.02, upon
surrender for registration of transfer of any Certificate at the offices of the
Certificate Registrar maintained for such purpose, the Certificate Registrar
shall execute and the Authenticating Agent shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Certificates of the same Class of a like aggregate Percentage Interest.

            (f) At the option of any Holder, its Certificates may be exchanged
for other Certificates of authorized denominations of the same Class of a like
aggregate Percentage Interest, upon surrender of the Certificates to be
exchanged at the offices of the Certificate Registrar maintained for such
purpose. Whenever any Certificates are so surrendered for exchange, the
Certificate Registrar shall execute and the Authenticating Agent shall
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive.

            (g) Every Certificate presented or surrendered for transfer or
exchange shall (if so required by the Certificate Registrar) be duly endorsed
by, or be accompanied by a written instrument of transfer in the form
satisfactory to the Certificate Registrar duly executed by, the Holder thereof
or his attorney duly authorized in writing.

            (h) No service charge shall be imposed for any transfer or exchange
of Certificates, but the Certificate Registrar may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any transfer or exchange of Certificates.

            (i) All Certificates surrendered for transfer and exchange shall be
physically canceled by the Certificate Registrar, and the Certificate Registrar
shall dispose of such canceled Certificates in accordance with its standard
procedures.

            (j) Upon request, the Certificate Registrar shall provide to the
Master Servicer, the Special Servicer and the Depositor notice of each transfer
of a Certificate and shall provide to each such Person with an updated copy of
the Certificate Register.

            (k) Each Person who has or who acquires any Ownership Interest in a
Certificate shall be deemed by the acceptance or acquisition of such Ownership
Interest to have agreed to be bound by the provisions of any Intercreditor
Agreement affecting such Certificate.

            Section 5.03 Book-Entry Certificates.

            (a) Each Class of Regular Certificates, the Class A-3SF Certificates
and the Class A-MFL Certificates shall initially be issued as one or more
Certificates registered in the name of the Depository or its nominee and, except
as provided in Section 5.03(c) below, transfer of such Certificates may not be
registered by the Certificate Registrar unless such transfer is to a successor
Depository that agrees to hold such Certificates for the respective Certificate
Owners with Ownership Interests therein. Such Certificate Owners shall hold and
transfer their respective Ownership Interests in and to such Certificates
through the book-entry facilities of the Depository and, except as provided in
Section 5.03(c) below, shall not be entitled to definitive, fully registered
Certificates ("Definitive Certificates") in respect of such Ownership Interests.
All transfers by Certificate Owners of their respective Ownership Interests in
the Book-Entry Certificates shall be made in accordance with the procedures
established by the Depository Participant or brokerage firm representing each
such Certificate Owner. Each Depository Participant shall only transfer the
Ownership Interests in the Book-Entry Certificates of Certificate Owners it
represents or of brokerage firms for which it acts as agent in accordance with
the Depository's normal procedures.

            (b) The Trustee, the Master Servicer, the Special Servicer, the
Depositor and the Certificate Registrar may for all purposes, including the
making of payments due on the Book-Entry Certificates, deal with the Depository
as the authorized representative of the Certificate Owners with respect to such
Certificates for the purposes of exercising the rights of Certificateholders
hereunder. The rights of Certificate Owners with respect to the Book-Entry
Certificates shall be limited to those established by law and agreements between
such Certificate Owners and the Depository Participants and brokerage firms
representing such Certificate Owners. Multiple requests and directions from, and
votes of, the Depository as Holder of the Book-Entry Certificates with respect
to any particular matter shall not be deemed inconsistent if they are made with
respect to different Certificate Owners. The Trustee may establish a reasonable
record date in connection with solicitations of consents from or voting by
Certificateholders and shall give notice to the Depository of such record date.

            (c) If (i)(A) the Depositor advises the Trustee and the Certificate
Registrar in writing that the Depository is no longer willing or able to
properly discharge its responsibilities with respect to a Class of the
Book-Entry Certificates, and (B) the Depositor is unable to locate a qualified
successor, or (ii) the Depositor at its option advises the Trustee and the
Certificate Registrar in writing that it elects to terminate the book-entry
system through the Depository with respect to a Class of Book-Entry
Certificates, the Certificate Registrar shall notify all affected Certificate
Owners, through the Depository, of the occurrence of any such event and of the
availability of Definitive Certificates to such Certificate Owners requesting
the same. Upon surrender to the Certificate Registrar of the Book-Entry
Certificates of any Class thereof by the Depository, accompanied by registration
instructions from the Depository for registration of transfer, the Certificate
Registrar shall execute, at the Depositor's expense, and the Authenticating
Agent shall authenticate and deliver, the Definitive Certificates in respect of
such Class to the Certificate Owners identified in such instructions. The
Depositor shall provide the Certificate Registrar with an adequate inventory of
Definitive Certificates. None of the Depositor, the Master Servicer, the Special
Servicer, the Trustee or the Certificate Registrar shall be liable for any delay
in delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Certificates for purposes of evidencing ownership of any Class of Registered
Certificates, the registered holders of such Definitive Certificates shall be
recognized as Certificateholders hereunder and, accordingly, shall be entitled
directly to receive payments on, to exercise Voting Rights with respect to, and
to transfer and exchange such Definitive Certificates.

            (d) Notwithstanding any other provisions contained herein, neither
the Trustee nor the Certificate Registrar shall have any responsibility
whatsoever to monitor or restrict the transfer of ownership interests in any
Certificate (including, but not limited to, any Non-Registered Certificate, any
Subordinated Certificate and any Class Z Certificate) which interests are
transferable through the book-entry facilities of the Depository.

            Section 5.04 Mutilated, Destroyed, Lost or Stolen Certificates.

            If (i) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Certificate Registrar receives evidence to its satisfaction of
the destruction, loss or theft of any Certificate, and (ii) there is delivered
to the Trustee and the Certificate Registrar such security or indemnity as may
be required by them to save each of them harmless, then, in the absence of
actual notice to the Trustee and the Certificate Registrar that such Certificate
has been acquired by a bona fide purchaser, the Certificate Registrar shall
execute and the Authenticating Agent shall authenticate and deliver, in exchange
for or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a
new Certificate of the same Class and like Percentage Interest. Upon the
issuance of any new Certificate under this Section, the Trustee and the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee and the
Certificate Registrar) connected therewith. Any replacement Certificate issued
pursuant to this Section shall constitute complete and indefeasible evidence of
ownership in the applicable REMIC created hereunder, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

            Section 5.05 Persons Deemed Owners.

            Prior to due presentment for registration of transfer, the
Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Certificate Registrar and any agent of any of them may treat the Person in whose
name any Certificate is registered as of the related Record Date as the owner of
such Certificate for the purpose of receiving distributions pursuant to Section
4.01 and may treat the person whose name each Certificate is registered as of
the date of determination as the owner of such Certificate for all other
purposes whatsoever and none of the Depositor, the Master Servicer, the Special
Servicer, the Trustee, the Certificate Registrar or any agent of any of them
shall be affected by notice to the contrary.

                                   ARTICLE VI

                 THE DEPOSITOR, THE MASTER SERVICER, THE SPECIAL
                SERVICER AND THE CONTROLLING CLASS REPRESENTATIVE

            Section 6.01 Liability of Depositor, Master Servicer and Special
Servicer.

            The Depositor, the Master Servicer and the Special Servicer shall be
liable in accordance herewith only to the extent of the respective obligations
specifically imposed upon and undertaken by the Depositor, the Master Servicer
and the Special Servicer herein.

            Section 6.02 Merger, Consolidation or Conversion of Depositor or
Master Servicer or Special Servicer.

            Subject to the following paragraph, the Depositor, the Master
Servicer and the Special Servicer shall each keep in full effect its existence,
rights and franchises as a corporation, or national banking association, as the
case may be, under the laws of the jurisdiction of its incorporation or
organization, and each will obtain and preserve its qualification to do business
as a national banking association or foreign corporation, as the case may be, in
each jurisdiction in which such qualification is or shall be necessary to
protect the validity and enforceability of this Agreement, the Certificates or
any of the Mortgage Loans and to perform its respective duties under this
Agreement, and the Master Servicer shall keep in full effect its existence and
rights as a national banking association under the laws of the United States.

            The Depositor, the Master Servicer or the Special Servicer may be
merged or consolidated with or into any Person (other than the Trustee), or
transfer all or substantially all of its assets (which may be limited to all or
substantially all of its assets related to commercial mortgage loan servicing)
to any Person, in which case any Person resulting from any merger or
consolidation to which the Depositor, the Master Servicer or the Special
Servicer shall be a party, or any Person succeeding to the business (which may
be limited to the commercial loan servicing business) of the Depositor, the
Master Servicer or the Special Servicer, shall be the successor of the
Depositor, the Master Servicer or the Special Servicer, as the case may be,
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that no successor or surviving Person shall
succeed to the rights of the Master Servicer or the Special Servicer unless (i)
as evidenced in writing by the Rating Agencies, such succession will not result
in qualification, downgrading or withdrawal of the ratings then assigned by the
Rating Agencies to any Class of Certificates and (ii) such successor or
surviving Person makes the applicable representations and warranties set forth
in Section 3.23.

            Section 6.03 Limitation on Liability of Depositor, Master Servicer
and Special Servicer.

            None of the Depositor, the Master Servicer or the Special Servicer,
or any director, officer, employee or agent of any of them, shall be under any
liability to the Trust Fund, the Trustee or the Certificateholders or the
Companion Holders for any action taken, or not taken, in good faith pursuant to
this Agreement, or for errors in judgment; provided, however, that this
provision shall not protect the Depositor, the Master Servicer or the Special
Servicer against any liability to the Trust Fund, the Trustee, the
Certificateholders or the Companion Holders for the breach of a representation,
warranty or covenant made herein by such party, or against any expense or
liability specifically required to be borne by such party without right of
reimbursement pursuant to the terms hereof, or against any liability which would
otherwise be imposed by reason of misfeasance, bad faith or negligence in the
performance of obligations or duties hereunder or negligent disregard of such
obligations and duties. The Depositor, the Master Servicer, the Special Servicer
and any director, officer, employee or agent of the Depositor, the Master
Servicer or the Special Servicer may rely in good faith on any document of any
kind which, prima facie, is properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Master Servicer,
the Special Servicer and any director, member, manager, officer, employee or
agent of the Depositor, the Master Servicer or the Special Servicer shall be
indemnified and held harmless by the Trust Fund against any loss, liability or
reasonable expense incurred in connection with this Agreement or the
Certificates (including, without limitation, the distribution or posting of
reports or other information as contemplated by this Agreement), other than any
loss, liability or expense: (i) specifically required to be borne by such party
without right of reimbursement pursuant to the terms hereof (including without
limitation, those expenses set forth in Section 3.11(b) or Section 3.11(d) and
the last sentence of the definition of Servicing Advances); (ii) incurred in
connection with any breach of a representation, warranty or covenant made
herein; or (iii) incurred by reason of willful misfeasance, bad faith or
negligence in the performance of obligations or duties hereunder. None of the
Depositor, the Master Servicer or the Special Servicer shall be under any
obligation to appear in, prosecute or defend any legal action unless such action
is related to its respective duties under this Agreement and unless it is
specifically required hereunder to bear the costs of such legal action, in its
opinion does not involve it in any ultimate expense or liability; provided,
however, that the Depositor, the Master Servicer or the Special Servicer may in
its discretion undertake any such action which it may deem necessary or
desirable with respect to the enforcement and/or protection of the rights and
duties of the parties hereto and the interests of the Certificateholders
hereunder. In such event, the legal expenses and costs of such action, and any
liability resulting therefrom, shall be expenses, costs and liabilities of the
Trust Fund, and the Depositor, the Master Servicer and the Special Servicer
shall be entitled to be reimbursed therefor from the Certificate Account as
provided in Section 3.05. In no event shall the Master Servicer or the Special
Servicer be liable or responsible for any action taken or omitted to be taken by
the other of them or by the Depositor, the Trustee, or any Certificateholder,
subject to the provisions of Section 8.05(b).

            With respect to the U-Haul Portfolio Loan, pursuant to the terms of
the MSCI 2005-HQ6 Pooling and Servicing Agreement, the MSCI 2005-HQ6 Master
Servicer, the MSCI 2005-HQ6 Special Servicer and any director, officer, employee
or agent of the MSCI 2005-HQ6 Master Servicer or the MSCI 2005-HQ6 Special
Servicer shall be indemnified and held harmless by the Trust Fund against the
U-Haul Portfolio Pari Passu Companion Loan's pro rata share of any and all
claims, losses, penalties, fines, forfeitures, legal fees and related costs,
judgments and any other costs, liabilities, fees and expenses incurred in
connection with any legal action that (i) relates to the MSCI 2005-HQ6 Pooling
and Servicing Agreement and/or this Agreement and (2) relates solely to the
servicing of the U-Haul Portfolio Whole Loan, other than any loss, liability or
expense incurred by reason of the MSCI 2005-HQ6 Master Servicer's willful
misfeasance, bad faith or negligence in the performance of duties under the MSCI
2005-HQ6 Pooling and Servicing Agreement.

            Section 6.04 Resignation of Master Servicer and the Special
Servicer.

            The Master Servicer and, subject to Section 6.09, the Special
Servicer may resign from the obligations and duties hereby imposed on it, upon a
determination that its duties hereunder are no longer permissible under
applicable law or are in material conflict by reason of applicable law with any
other activities carried on by it (the other activities of the Master Servicer
or the Special Servicer, as the case may be, so causing such a conflict being of
a type and nature carried on by the Master Servicer or the Special Servicer, as
the case may be, at the date of this Agreement). Any such determination
requiring the resignation of the Master Servicer or the Special Servicer, as
applicable, shall be evidenced by an Opinion of Counsel to such effect which
shall be delivered to the Trustee. Unless applicable law requires the Master
Servicer's or Special Servicer's resignation to be effective immediately, and
the Opinion of Counsel delivered pursuant to the prior sentence so states, no
such resignation shall become effective until the Trustee or other successor
shall have assumed the responsibilities and obligations of the resigning party
in accordance with Section 7.02 hereof. The Master Servicer and the Special
Servicer shall have the right to resign at any other time; provided that (i) a
willing successor thereto has been found by the Master Servicer or Special
Servicer, as applicable, (ii) each of the Rating Agencies confirms in writing
that the successor's appointment will not result in a withdrawal, qualification
or downgrade of any rating or ratings assigned to any Class of Certificates,
(iii) the resigning party pays all costs and expenses in connection with such
transfer, and (iv) the successor accepts appointment prior to the effectiveness
of such resignation. Neither the Master Servicer nor the Special Servicer shall
be permitted to resign except as contemplated above in this Section 6.04.

            Consistent with the foregoing, neither the Master Servicer nor the
Special Servicer shall, except as expressly provided herein, assign or transfer
any of its rights, benefits or privileges hereunder to any other Person, or,
except as provided in Sections 3.22 and 4.06, delegate to or subcontract with,
or authorize or appoint any other Person to perform any of the duties, covenants
or obligations to be performed by it hereunder. If, pursuant to any provision
hereof, the duties of the Master Servicer or the Special Servicer are
transferred to a successor thereto, the Master Servicing Fee or the Special
Servicing Fee, as the case may be, that accrues pursuant hereto from and after
the date of such transfer shall be payable to such successor.

            Section 6.05 Rights of Depositor and Trustee in Respect of Master
Servicer and the Special Servicer.

            The Master Servicer and the Special Servicer shall each afford the
Depositor, the Underwriters and the Trustee, upon reasonable notice, during
normal business hours access to all records maintained thereby in respect of its
rights and obligations hereunder and access to officers thereof responsible for
such obligations. Upon reasonable request, the Master Servicer and the Special
Servicer shall each furnish the Depositor, the Underwriters and the Trustee with
its most recent publicly available financial statements and such other
information as it possesses, and which it is not prohibited by applicable law or
contract from disclosing, regarding its business, affairs, property and
condition, financial or otherwise, except to the extent such information
constitutes proprietary information or is subject to a privilege under
applicable law. The Depositor may, but is not obligated to, enforce the
obligations of the Master Servicer and the Special Servicer hereunder and may,
but is not obligated to, perform, or cause a designee to perform, any defaulted
obligation of the Master Servicer or Special Servicer hereunder or exercise the
rights of the Master Servicer and the Special Servicer hereunder; provided,
however, that neither the Master Servicer nor the Special Servicer shall be
relieved of any of its obligations hereunder by virtue of such performance by
the Depositor or its designee; provided, further, that the Depositor may not
exercise any right pursuant to Section 7.01 to terminate the Master Servicer or
the Special Servicer as a party to this Agreement. The Depositor shall not have
any responsibility or liability for any action or failure to act by the Master
Servicer or the Special Servicer and is not obligated to supervise the
performance of the Master Servicer or the Special Servicer under this Agreement
or otherwise.

            Section 6.06 Depositor, Master Servicer and Special Servicer to
Cooperate with Trustee.

            The Depositor, the Master Servicer and the Special Servicer shall
each furnish such reports, certifications and information as are reasonably
requested by the Trustee in order to enable it to perform its duties hereunder.

            Section 6.07 Depositor, Special Servicer and Trustee to Cooperate
with Master Servicer.

            The Depositor, the Special Servicer and the Trustee shall each
furnish such reports, certifications and information as are reasonably requested
by the Master Servicer in order to enable it to perform its duties hereunder.

            Section 6.08 Depositor, Master Servicer and Trustee to Cooperate
with Special Servicer.

            The Depositor, the Master Servicer and the Trustee shall each
furnish such reports, certifications and information as are reasonably requested
by the Special Servicer in order to enable it to perform its duties hereunder.

            Section 6.09 Designation of Special Servicer by the Controlling
Class and Controlling Holders.

            The Holder or Holders of the Certificates evidencing a majority of
the Voting Rights allocated to the Controlling Class may at any time and from
time to time designate a Person meeting the requirements set forth in Section
6.04 (including, without limitation, Rating Agency confirmation) to serve as
Special Servicer hereunder and to replace any existing Special Servicer or any
Special Servicer that has resigned or otherwise ceased to serve as Special
Servicer; provided that such Holder or Holders shall pay all costs related to
the transfer of servicing if the Special Servicer is replaced other than due to
an Event of Default. Such Holder or Holders may also select a Controlling Class
Representative that may advise and direct the Special Servicer and whose
approval is required for certain actions, as described herein. Such Holder or
Holders shall so designate a Person to serve as replacement Special Servicer by
the delivery to the Trustee, the Master Servicer and the existing Special
Servicer of a written notice stating such designation. The Trustee shall,
promptly after receiving any such notice, deliver to the Rating Agencies an
executed Notice and Acknowledgment in the form attached hereto as Exhibit I-1.
If such Holders have not replaced the Special Servicer within 30 days of such
Special Servicer's resignation or the date such Special Servicer has ceased to
serve in such capacity, the Trustee shall designate a successor Special Servicer
meeting the requirements set forth in Section 6.04. Any designated Person shall
become the Special Servicer, subject to satisfaction of the other conditions set
forth below, on the date that the Trustee shall have received written
confirmation from all of the Rating Agencies that the appointment of such Person
will not result in the qualification, downgrading or withdrawal of the rating or
ratings assigned to one or more Classes of the Certificates. The appointment of
such designated Person as Special Servicer shall also be subject to receipt by
the Trustee of (1) an Acknowledgment of Proposed Special Servicer in the form
attached hereto as Exhibit I-2, executed by the designated Person, and (2) an
Opinion of Counsel (at the expense of the Person designated to become the
Special Servicer) to the effect that the designation of such Person to serve as
Special Servicer is in compliance with this Section 6.09 and all other
applicable provisions of this Agreement, that upon the execution and delivery of
the Acknowledgment of Proposed Special Servicer the designated Person shall be
bound by the terms of this Agreement and that this Agreement shall be
enforceable against the designated Person in accordance with its terms. Any
existing Special Servicer shall be deemed to have resigned simultaneously with
such designated Person's becoming the Special Servicer hereunder; provided,
however, that the resigning Special Servicer shall continue to be entitled to
receive all amounts accrued or owing to it under this Agreement on or prior to
the effective date of such resignation (including Workout Fees as set forth in
Section 3.11(c) of this Agreement), and it shall continue to be entitled to the
benefits of Section 6.03 notwithstanding any such resignation. Such resigning
Special Servicer shall cooperate with the Trustee and the replacement Special
Servicer in effecting the termination of the resigning Special Servicer's
responsibilities and rights hereunder, including, without limitation, the
transfer within two Business Days to the replacement Special Servicer for
administration by it of all cash amounts that shall at the time be or should
have been credited by the Special Servicer to the Certificate Account or the REO
Account or delivered to the Master Servicer or that are thereafter received with
respect to Specially Serviced Mortgage Loans and REO Properties.

            Notwithstanding the foregoing, in accordance with the terms of the
related Intercreditor Agreement, the Companion Holder(s) related to the
AmericasMart Loan, the 101 Avenue of the Americas Loan and the U-Haul Portfolio
Loan shall have the right to appoint, approve and/or remove the Special Servicer
with respect to the related Mortgage Loan, and the Controlling Class shall not
have the right to replace the Special Servicer with respect to such Mortgage
Loans as described above. In addition, the Companion Holder related to the
Westfield San Francisco Centre Loan has the right to replace the Special
Servicer with respect to the Westfield San Francisco Centre Whole Loan pursuant
to the terms of the related Intercreditor Agreement. In addition, the Companion
Holder related to the NGP Rubicon GSA Pool Loan will have the right to consent
to any replacement of the special servicer with respect to the NGP Rubicon GSA
Pool Whole Loan.

            Section 6.10 Master Servicer or Special Servicer as Owner of a
Certificate.

            The Master Servicer or an Affiliate of the Master Servicer or the
Special Servicer or an Affiliate of the Special Servicer may become the Holder
of (or, in the case of a Book-Entry Certificate, Certificate Owner with respect
to) any Certificate with (except as set forth in the definition of
"Certificateholder") the same rights it would have if it were not the Master
Servicer or the Special Servicer or an Affiliate thereof. If, at any time during
which the Master Servicer or the Special Servicer or an Affiliate of the Master
Servicer or the Special Servicer is the Holder of (or, in the case of a
Book-Entry Certificate, Certificate Owner with respect to) any Certificate, the
Master Servicer or the Special Servicer proposes to take action (including for
this purpose, omitting to take action) that (i) is not expressly prohibited by
the terms hereof and would not, in the Master Servicer's or the Special
Servicer's good faith judgment, violate the Servicing Standard, and (ii) if
taken, might nonetheless, in the Master Servicer's or the Special Servicer's
reasonable, good faith judgment, be considered by other Persons to violate the
Servicing Standard, then the Master Servicer or the Special Servicer may (but
need not) seek the approval of the Certificateholders to such action by
delivering to the Trustee a written notice that (a) states that it is delivered
pursuant to this Section 6.10, (b) identifies the Percentage Interest in each
Class of Certificates beneficially owned by the Master Servicer or the Special
Servicer or an Affiliate of the Master Servicer or the Special Servicer, and (c)
describes in reasonable detail the action that the Master Servicer or the
Special Servicer proposes to take. The Trustee, upon receipt of such notice,
shall forward it to the Certificateholders (other than the Master Servicer and
its Affiliates or the Special Servicer and its Affiliates, as appropriate),
together with such instructions for response as the Trustee shall reasonably
determine. If at any time Certificateholders holding greater than 50% of the
Voting Rights of all Certificateholders (calculated without regard to the
Certificates beneficially owned by the Master Servicer or its Affiliates or the
Special Servicer or its Affiliates) shall have failed to object in writing to
the proposal described in the written notice, and if the Master Servicer or the
Special Servicer shall act as proposed in the written notice within thirty (30)
days, such action shall be deemed to comply with, but not modify, the Servicing
Standard. The Trustee shall be entitled to reimbursement from the Master
Servicer or the Special Servicer, as applicable, for the reasonable expenses of
the Trustee incurred pursuant to this paragraph. It is not the intent of the
foregoing provision that the Master Servicer or the Special Servicer be
permitted to invoke the procedure set forth herein with respect to routine
servicing matters arising hereunder, but rather in the case of unusual
circumstances.

            Section 6.11 The Controlling Class Representative.

            (a) Subject to Sections 6.11(c) through (h), the Controlling Class
Representative will be entitled to advise the Special Servicer with respect to
the following actions of the Special Servicer, and notwithstanding anything
herein to the contrary except as necessary or advisable to avoid an Adverse
REMIC Event or the violation of the Servicing Standard and except as set forth
in, and in any event subject to, the second paragraph of this Section 6.11(a),
the Special Servicer will not be permitted to take any of the following actions
as to which the Controlling Class Representative has objected in writing within
ten Business Days of being notified thereof, which notification with respect to
the action described in clause (vi) below shall be copied by the Special
Servicer to the Master Servicer (provided that, if such written objection has
not been received by the Special Servicer within such ten Business Day period,
then the Controlling Class Representative's approval will be deemed to have been
given):

            (i) any actual or proposed foreclosure upon or comparable conversion
      (which may include acquisitions of an REO Property) of the ownership of
      properties securing such of the Specially Serviced Mortgage Loans as come
      into and continue in default;

            (ii) any modification of a Money Term of a Mortgage Loan (other than
      a modification consisting of the extension of the maturity date of a
      Mortgage Loan for one year or less) or a material non-monetary term;

            (iii) any actual or proposed sale of an REO Property (other than in
      connection with the termination of the Trust Fund or pursuant to Section
      3.18);

            (iv) any determination to bring an REO Property into compliance with
      applicable environmental laws or to otherwise address Hazardous Materials
      located at an REO Property;

            (v) any acceptance of substitute or additional collateral or release
      of material collateral for a Mortgage Loan unless required by the
      underlying loan documents;

            (vi) any waiver of a "due-on-sale" clause or "due-on-encumbrance"
      clause;

            (vii) any release of any performance or "earn-out" reserves, escrows
      or letters of credit;

            (viii) any acceptance of an assumption agreement releasing a
      borrower from liability under a Mortgage Loan (other than in connection
      with a defeasance permitted under the terms of the applicable Mortgage
      Loan documents);

            (ix) any termination of the related property manager for Mortgage
      Loans having an outstanding principal balance of greater than $5,000,000;

            (x) any termination of, or modification of, any applicable franchise
      agreement related to any Mortgage Loan secured by a hotel;

            (xi) any determination to allow a borrower not to maintain terrorism
      insurance; and

            (xii) any determination to decrease the time period referenced in
      clause (g) of the definition of Specially Serviced Mortgage Loan.

            In addition, the Controlling Class Representative may direct the
Special Servicer to take, or to refrain from taking, such other actions as the
Controlling Class Representative may deem advisable or as to which provision is
otherwise made in this Agreement; provided that, notwithstanding anything herein
to the contrary or anything in this Agreement which permits the Controlling
Class Representative or a Companion Holder the right to consent to or object to
actions taken by the Special Servicer, no such advice or direction, and no
objection contemplated by the preceding paragraph may require or cause the
Special Servicer to violate any applicable law, any provision of this Agreement
or the REMIC Provisions (and the Special Servicer shall disregard any such
direction or objection), including without limitation the Special Servicer's
obligation to act in accordance with the Servicing Standard, or expose the
Master Servicer, the Special Servicer, the Trust Fund or the Trustee or their
respective Affiliates, officers, directors, employees or agents to any claim,
suit or liability, or materially expand the scope of the Special Servicer or the
Special Servicer's responsibilities hereunder or cause the Special Servicer to
act, or fail to act, in a manner which in the reasonable judgment of the Special
Servicer is not in the best interests of the Certificateholders. For the
avoidance of doubt, the Master Servicer and/or the Special Servicer will
disregard any direction or objection of any party (including without limitation
of the Controlling Class Representative or a Companion Holder) if such direction
and or objection causes the Master Servicer or the Special Servicer to violate
the Servicing Standard, any applicable law, any provision of this Agreement or
the REMIC Provisions or expose the Master Servicer, the Special Servicer, the
Trust Fund, the Paying Agent or the Trustee or their respective Affiliates,
officers, directors employees or agents to any claim, suit or liability, or
materially expand the scope of the Master Servicer's or Special Servicer's
responsibility hereunder or cause the Master Servicer or the Special Servicer to
act, or fail to act, in a manner which in the reasonable judgment of the Master
Servicer or the Special Servicer is not in the best interest of the
Certificateholders, or the holders of the Companion Loan and consistent with the
Servicing Standard.

            (b) The Controlling Class Representative, the Controlling Class and
the Holder of any Companion Loan will have no liability to the
Certificateholders for any action taken, or for refraining from the taking of
any action, or for errors in judgment; provided, however, that the Controlling
Class Representative, the Controlling Class and the Holder of any Companion Loan
will not be protected against any liability to a Controlling Class
Certificateholder which would otherwise be imposed by reason of willful
misfeasance, bad faith or negligence in the performance of duties or by reason
of reckless disregard of obligations or duties. By its acceptance of a
Certificate, each Certificateholder confirms its understanding that the
Controlling Class, the Controlling Class Representatives or any Holder of a
Companion Loan may take actions that favor the interests of one or more Classes
of the Certificates over other Classes of the Certificates, and that the
Controlling Class, the Controlling Class Representative and the Holder of any
Companion Loan may have special relationships and interests that conflict with
those of Holders of some Classes of the Certificates, that the Controlling
Class, the Controlling Class Representatives or any Holder of a Companion Loan
may act solely in the interests of the Holders of the Controlling Class or any
Companion Holder, as the case may be, and that the Controlling Class
Representatives do not have any duties or liability to the Holders of any Class
of Certificates other than the Controlling Class or any Companion Holder and
shall have no liability whatsoever for having so acted, and no Certificateholder
may take any action whatsoever against the Controlling Class Representatives or
any Holder of any Companion Loan or any director, officer, employee, agent or
principal thereof for having so acted.

            (c) Notwithstanding anything to the contrary in this Section 6.11 or

                                     DEFAULT

            Section 7.01 Events of Default.

            (a) "Event of Default," wherever used herein, means any one of the
following events:

            (i) any failure by the Master Servicer to deposit into the
      Certificate Account, which failure, in the case of deposits and remittance
      to the Certificate Account, continues unremedied one Business Day after
      the date upon which such deposit was required to have been made hereunder,
      or to deposit into, or remit to the Paying Agent for deposit into the
      Distribution Account, the Class A-3SF Floating Rate Account or the Class
      A-MFL Floating Rate Account, any amount (other than a P&I Advance)
      required to be so deposited or remitted by it under this Agreement, which
      failure, in the case of deposits and remittances to the Distribution
      Account, the Class A-3SF Floating Rate Account or the Class A-MFL Floating
      Rate Account, continues unremedied until 10:00 a.m., New York City time on
      the related Distribution Date; provided, however, that to the extent the
      Master Servicer does not timely make such remittances, the Master Servicer
      shall pay the Trustee for the account of the Trustee interest on any
      amount not timely remitted at the Prime Rate from and including the
      applicable required remittance date to but not including the date such
      remittance is actually made; or

            (ii) any failure by the Special Servicer to timely deposit into the
      REO Account or to timely deposit into, or to timely remit to the Master
      Servicer for deposit into, the Certificate Account, any amount required to
      be so deposited or remitted under this Agreement; or

            (iii) any failure by the Master Servicer to timely make any
      Servicing Advance required to be made by it hereunder, which Servicing
      Advance remains unmade for a period of five Business Days following the
      date on which notice shall have been given to the Master Servicer, as the
      case may be, by the Trustee as provided in Section 3.03(c); or

            (iv) any failure on the part of the Master Servicer or the Special
      Servicer duly to observe or perform in any material respect any other of
      the covenants or agreements on the part of the Master Servicer or the
      Special Servicer, as the case may be, contained in this Agreement which
      continues unremedied for a period of 30 days after the date on which
      written notice of such failure, requiring the same to be remedied, shall
      have been given to the Master Servicer or the Special Servicer, as the
      case may be, by any other party hereto or the Master Servicer or the
      Special Servicer, as the case may be (with a copy to each other party
      hereto), by the Holders of Certificates entitled to at least 25% of the
      Voting Rights; provided, however, that with respect to any such failure
      which is not curable within such 30-day period, the Master Servicer or the
      Special Servicer, as the case may be, shall have an additional cure period
      of thirty (30) days to effect such cure so long as the Master Servicer or
      the Special Servicer, as the case may be, has commenced to cure such
      failure within the initial 30-day period and has provided the Trustee with
      an Officer's Certificate certifying that it has diligently pursued, and is
      continuing to pursue, a full cure; or

            (v) any breach on the part of the Master Servicer or the Special
      Servicer of any representation or warranty contained in this Agreement
      that materially and adversely affects the interests of any Class of
      Certificateholders and which continues unremedied for a period of 30 days
      after the date on which notice of such breach, requiring the same to be
      remedied, shall have been given to the Master Servicer or the Special
      Servicer, as the case may be, by any other party hereto or the Master
      Servicer or the Special Servicer, as the case may be (with a copy to each
      other party hereto), by the Holders of Certificates entitled to at least
      25% of the Voting Rights; provided, however, with respect to any failure
      which is not curable within such 30-day period, the Master Servicer or the
      Special Servicer, as the case may be, shall have an additional cure period
      of thirty (30) days so long as the Master Servicer or the Special
      Servicer, as the case may be, has commenced to cure within the initial
      30-day period and provided the Trustee with an Officer's Certificate
      certifying that it has diligently pursued, and is continuing to pursue, a
      full cure; or

            (vi) a decree or order of a court or agency or supervisory authority
      having jurisdiction in the premises in an involuntary case under any
      present or future federal or state bankruptcy, insolvency or similar law
      for the appointment of a conservator, receiver, liquidator, trustee or
      similar official in any bankruptcy, insolvency, readjustment of debt,
      marshaling of assets and liabilities or similar proceedings, or for the
      winding-up or liquidation of its affairs, shall have been entered against
      the Master Servicer or the Special Servicer and such decree or order shall
      have remained in force undischarged or unstayed for a period of sixty (60)
      days; or

            (vii) the Master Servicer or the Special Servicer shall consent to
      the appointment of a conservator, receiver, liquidator, trustee or similar
      official in any bankruptcy, insolvency, readjustment of debt, marshaling
      of assets and liabilities or similar proceedings of or relating to it or
      of or relating to all or substantially all of its property; or

            (viii) the Master Servicer or the Special Servicer shall admit in
      writing its inability to pay its debts generally as they become due, file
      a petition to take advantage of any applicable bankruptcy, insolvency or
      reorganization statute, make an assignment for the benefit of its
      creditors, voluntarily suspend payment of its obligations, or take any
      corporate action in furtherance of the foregoing; or

            (ix) the consolidated net worth of the Master Servicer and of its
      direct or indirect parent, determined in accordance with generally
      accepted accounting principles, shall decline to less than $15,000,000; or

            (x) the Master Servicer or the Special Servicer receives actual
      knowledge that Moody's has (i) qualified, downgraded or withdrawn its
      rating or ratings of, one or more Classes of Certificates, or (ii) placed
      one or more Classes of Certificates on "watch status" in contemplation of
      rating downgrade or withdrawal (and such "watch status" placement shall
      not have been withdrawn by Moody's within 60 days of the date that the
      Master Servicer or the Special Servicer obtained such actual knowledge)
      and, in the case of either of clauses (i) or (ii), citing servicing
      concerns with the Master Servicer or the Special Servicer, as applicable,
      as the sole or material factor in such rating action; or

            (xi) the Trustee has received a written notice from Fitch (which the
      Trustee is required to promptly forward to the Master Servicer, the
      Special Servicer or the Paying Agent, as applicable), to the effect that
      if the Master Servicer or the Special Servicer, as applicable, continues
      to act in such capacity, the rating or ratings on one or more Classes of
      Certificates will be downgraded or withdrawn, citing servicing concerns
      relating to the Master Servicer or the Special Servicer, as the case may
      be, as the sole or material factor in such action; provided, such Master
      Servicer or the Special Servicer, as applicable, shall have 60 days to
      resolve such matters to the satisfaction of Fitch (or such longer time
      period as may be agreed in writing by Fitch) prior to the replacement of
      the Master Servicer or the Special Servicer or the downgrade of any Class
      of Certificates; or

            (xii) the Master Servicer or the Special Servicer, as the case may
      be, is no longer listed on S&P's Select Servicer List as a U.S. Commercial
      Mortgage Master Servicer or a U.S. Commercial Mortgage Special Servicer,
      as the case may be, and such removal continues for a period of 60 days; or

            (xiii) the Master Servicer shall fail to remit to the Paying Agent
      for deposit into the Distribution Account, on any P&I Advance Date, the
      full amount of P&I Advances required to be made on such date, which
      failure continues unremedied until 10:00 a.m. New York City time on the
      next Business Day succeeding such P&I Advance Date; provided, however,
      that to the extent the Master Servicer does not timely make such
      remittances, the Master Servicer shall pay the Trustee or the Fiscal Agent
      for the account of the Trustee or the Fiscal Agent, respectively, interest
      on any amount not timely remitted at the Prime Rate from and including the
      applicable required remittance date to but not including the date such
      remittance is actually made.

            (b) If any Event of Default shall occur with respect to the Master
Servicer or the Special Servicer (in either case, for purposes of this Section
7.01(b), the "Defaulting Party") and shall be continuing, then, and in each and
every such case, so long as such Event of Default shall not have been remedied,
the Depositor and/or the Trustee may, and at the written direction of the
Holders of Certificates entitled to at least 25% of the Voting Rights, the
Trustee shall, by notice in writing to the Defaulting Party (with a copy of such
notice to each other party hereto and the Rating Agencies), terminate all of the
rights and obligations (but not the liabilities for actions and omissions
occurring prior thereto) of the Defaulting Party under this Agreement and in and
to the Trust Fund, other than its rights as a Certificateholder hereunder.
Notwithstanding the foregoing, it is acknowledged and agreed that the Depositor
shall have no obligation to exercise any of the preceding rights and/or powers.
From and after the receipt by the Defaulting Party of such written notice of
termination, all authority and power of the Defaulting Party under this
Agreement, whether with respect to the Certificates (other than as a holder of
any Certificate) or the Mortgage Loans or otherwise, shall pass to and be vested
in the Trustee pursuant to and under this Section, and, without limitation, the
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
and at the expense of the Defaulting Party, as attorney-in-fact or otherwise,
any and all documents and other instruments, and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Mortgage Loans and related documents, or otherwise. The Master Servicer and
the Special Servicer each agree that, if it is terminated pursuant to this
Section 7.01(b), it shall promptly (and in any event no later than ten Business
Days subsequent to its receipt of the notice of termination) provide the Trustee
with all documents and records, including those in electronic form, requested
thereby to enable the Trustee or a successor Master Servicer or Special Servicer
to assume the Master Servicer's or Special Servicer's, as the case may be,
functions hereunder, and shall cooperate with the Trustee in effecting the
termination of the Master Servicer's or Special Servicer's, as the case may be,
responsibilities and rights hereunder, including, without limitation, (i) the
immediate transfer to the Trustee or a successor Master or Special Servicer for
administration by it of all cash amounts that shall at the time be or should
have been credited by the Master Servicer to the Certificate Account, the
Distribution Account, a Servicing Account or a Reserve Account (if the Master
Servicer is the Defaulting Party) or that are thereafter received by or on
behalf of it with respect to any Mortgage Loan or (ii) the transfer within two
Business Days to the Trustee or a successor Special Servicer for administration
by it of all cash amounts that shall at the time be or should have been credited
by the Special Servicer to the REO Account, the Certificate Account, a Servicing
Account or a Reserve Account or delivered to the Master Servicer (if the Special
Servicer is the Defaulting Party) or that are thereafter received by or on
behalf of it with respect to any Mortgage Loan or REO Property (provided,
however, that the Master Servicer and the Special Servicer each shall, if
terminated pursuant to this Section 7.01(b), continue to be entitled to receive
all amounts accrued or owing to it under this Agreement on or prior to the date
of such termination, whether in respect of Advances or otherwise, and it shall
continue to be entitled to the benefits of Section 6.03 notwithstanding any such
termination). Any cost or expenses in connection with any actions to be taken by
the Master Servicer, the Special Servicer or the Trustee pursuant to this
paragraph shall be borne by the Defaulting Party and if not paid by the
Defaulting Party within 90 days after the presentation of reasonable
documentation of such costs and expenses, such expense shall be reimbursed by
the Trust Fund; provided, however, that the Defaulting Party shall not thereby
be relieved of its liability for such expenses. If and to the extent that the
Defaulting Party has not reimbursed such costs and expenses, the Trustee shall
have an affirmative obligation to take all reasonable actions to collect such
expenses on behalf of and at the expense of the Trust Fund. For purposes of this
Section 7.01 and of Section 7.03(b), the Trustee shall not be deemed to have
knowledge of an event which constitutes, or which with the passage of time or
notice, or both, would constitute an Event of Default described in clauses
(i)-(viii) of subsection (a) above unless a Responsible Officer of the Trustee
has actual knowledge thereof or unless notice of any event which is in fact such
an Event of Default is received by the Trustee and such notice references the
Certificates, the Trust Fund or this Agreement.

            (c) If the Master Servicer receives a notice of termination under
Section 7.01(b) solely due to an Event of Default under Section 7.01(a)(x)
and/or (xi) and/or (xii) and if the terminated Master Servicer provides the
Trustee with the appropriate "request for proposal" materials within the five
Business Days after receipt of such termination notice, the Master Servicer
shall continue to serve as Master Servicer hereunder until a successor Master
Servicer is selected in accordance with this Section 7.01(c); provided the
Trustee has requested the Master Servicer to continue to serve as the Master
Servicer during such period. Upon receipt of the "request for proposal"
materials, the Trustee shall promptly thereafter (using such "request for
proposal" materials provided by the terminated Master Servicer) solicit good
faith bids for the rights to master service the Mortgage Loans under this
Agreement from at least three (3) Persons qualified to act as Master Servicer
hereunder in accordance with Sections 6.02 and 7.02 (any such Person so
qualified, a "Qualified Bidder") or, if three (3) Qualified Bidders cannot be
located, then from as many Persons as the Trustee can determine are Qualified
Bidders; provided that, at the Trustee's request, the Master Servicer to be
terminated pursuant to Section 7.01(b) shall supply the Trustee with the names
of Persons from whom to solicit such bids; provided, further, that the Trustee
shall not be responsible if less than three (3) or no Qualified Bidders submit
bids for the right to master service the Mortgage Loans under this Agreement.
The bid proposal shall require any Successful Bidder (as defined below), as a
condition of such bid, to enter into this Agreement as successor Master
Servicer, and to agree to be bound by the terms hereof, within 45 days after the
notice of termination to the Master Servicer. The materials provided to the
Trustee shall provide for soliciting bids (i) on the basis of such successor
Master Servicer retaining all Sub-Servicers to continue the primary servicing of
the Mortgage Loans pursuant to the terms of the respective Sub-Servicing
Agreements and to enter into a Sub-Servicing Agreement with the terminated
Master Servicer to service each of the Mortgage Loans not subject to a
Sub-Servicing Agreement at a servicing fee rate per annum equal to the Master
Servicing Fee Rate minus 2.0 basis points per Mortgage Loan serviced (each, a
"Servicing-Retained Bid") and (ii) on the basis of terminating each
Sub-Servicing Agreement and Sub-Servicer that it is permitted to terminate in
accordance with Section 3.22 (each, a "Servicing-Released Bid"). The Trustee
shall select the Qualified Bidder with the highest cash Servicing-Retained Bid
(or, if none, the highest cash Servicing Released Bid) (the "Successful Bidder")
to act as successor Master Servicer hereunder. The Trustee shall direct the
Successful Bidder to enter into this Agreement as successor Master Servicer
pursuant to the terms hereof (and, if the successful bid was a
Servicing-Retained Bid, to enter into a Sub-Servicing Agreement with the
terminated Master Servicer as contemplated above), no later than 45 days after
termination of the Master Servicer.

            Upon the assignment and acceptance of the master servicing rights
hereunder to and by the Successful Bidder, the Trustee shall remit or cause to
be remitted (i) if the successful bid was a Servicing-Retained Bid, to the
Master Servicer to be terminated pursuant to Section 7.01(b) the amount of such
cash bid received from the Successful Bidder (net of "out-of-pocket" expenses
incurred in connection with obtaining such bid and transferring servicing) and
(ii) if the successful bid was a Servicing-Released Bid, to the Master Servicer
and each terminated Sub-Servicer its respective Bid Allocation. In connection
with such remittance, the Trustee is entitled to be reimbursed by the Master
Servicer for the Trustee's "out-of-pocket" expenses incurred in connection with
obtaining such bid and transferring servicing as contemplated by clause (i) of
this paragraph and by the definition of "Bid Allocation".

            If the Successful Bidder has not entered into this Agreement as
successor Master Servicer within such 45-day period or no Successful Bidder was
identified within such 45-day period, the Master Servicer to be terminated
pursuant to Section 7.01(b) shall reimburse the Trustee for all reasonable
"out-of-pocket" expenses incurred by the Trustee in connection with such bid
process and the Trustee shall have no further obligations under this Section
7.01(c). The Trustee thereafter may act or may select a successor to act as
Master Servicer hereunder in accordance with Section 7.02.

            (d) Notwithstanding the foregoing, with respect to the Westfield San
Francisco Centre Loan and the NGP Rubicon GSA Pool Loan, if any Event of Default
on the part of the Master Servicer occurs under this Agreement that materially
and adversely affects the related Companion Holder, and the Master Servicer is
not otherwise terminated in accordance with the terms of this Agreement, then
the Master Servicer may not be terminated by or at the direction of such
Companion Holder; provided that in such event, at the request of such Companion
Holder, the Master Servicer shall appoint, within 30 days of the Companion
Holder's request, a sub-servicer (or replacement sub-servicer, as the case may
be) mutually selected by the Master Servicer and the related Companion Holder
with respect to the Westfield San Francisco Centre Loan or the NGP Rubicon GSA
Pool Loan, as applicable, such appointment or replacement to be effected in
accordance with the terms and provisions of this Agreement and the related Pari
Passu Loan Intercreditor Agreement, which appointment will be conditioned upon
written confirmation from each Rating Agency rating any of the certificates
issued in connection with the securitization of the related Pari Passu Companion
Loan that such appointment will not result in a downgrade, qualification or
withdrawal of the then current rating assigned to any of the certificates issued
in connection with such securitization.

            (e) Notwithstanding the foregoing, if the Trustee or the Master
Servicer has received notice from Moody's, S&P or Fitch that the Master Servicer
is no longer approved by Moody's or Fitch or is no longer listed on S&P's Select
Servicer List as a U.S. Commercial Mortgage Master Servicer, then the Trustee or
Master Servicer shall promptly notify the other and the MSCI 2005-HQ6 Master
Servicer and the MSCI 2005-HQ6 Trustee of the same.

            Section 7.02 Trustee to Act; Appointment of Successor.

            On and after the time the Master Servicer or the Special Servicer
resigns pursuant to Section 6.04 or receives a notice of termination pursuant to
Section 7.01, the Trustee shall, unless a successor is appointed pursuant to
Section 6.04, be the successor in all respects to the Master Servicer or the
Special Servicer, as the case may be, in its capacity as such under this
Agreement and the transactions set forth or provided for herein and shall have
all (and the former Master Servicer or the Special Servicer, as the case may be,
shall cease to have any) of the responsibilities, duties and liabilities (except
as provided in the next sentence) of the Master Servicer or the Special
Servicer, as the case may be, arising thereafter, including, without limitation,
if the Master Servicer is the resigning or terminated party, the Master
Servicer's obligation to make P&I Advances, the unmade P&I Advances that gave
rise to such Event of Default; provided that, if the Master Servicer is the
resigning or terminated party, and if after the Closing Date the Trustee is
prohibited by law or regulation from obligating itself to make P&I Advances (as
evidenced by an Opinion of Counsel delivered to the Depositor and the Rating
Agencies) the Trustee shall not be obligated to make such P&I Advances;
provided, further, that any failure to perform such duties or responsibilities
caused by the Master Servicer's or the Special Servicer's, as the case may be,
failure to provide information or monies required by Section 7.01 shall not be
considered a default by the Trustee hereunder. Notwithstanding anything contrary
in this Agreement, the Trustee shall in no event be held responsible or liable
with respect to any of the acts, omissions, representations and warranties of
the resigning or terminated party (other than the Trustee) or for any losses
incurred by such resigning or terminated party pursuant to Section 3.06
hereunder nor shall the Trustee be required to purchase any Mortgage Loan
hereunder. As compensation therefor, the Trustee shall be entitled to all fees
and other compensation which the resigning or terminated party would have been
entitled to if the resigning or terminated party had continued to act hereunder
(other than fees already earned, including, without limitation, Workout Fees).
Notwithstanding the above and subject to its obligations under Section 3.22(d)
and 7.01(b), the Trustee may, if it shall be unwilling in its sole discretion to
so act as either Master Servicer or Special Servicer, as the case may be, or
shall, if it is unable to so act as either Master Servicer or Special Servicer,
as the case may be, or shall, if the Trustee is not approved as a master
servicer or a special servicer, as the case may be, by any of the Rating
Agencies or if the Holders of Certificates entitled to at least 51% of the
Voting Rights so request in writing to the Trustee, promptly appoint, subject to
the approval of each of the Rating Agencies (as evidenced by written
confirmation therefrom to the effect that the appointment of such institution
would not cause the qualification, downgrading or withdrawal of the then current
rating on any Class of Certificates) or petition a court of competent
jurisdiction to appoint, any established mortgage loan servicing institution
that meets the requirements of Section 6.02 (including, without limitation,
rating agency confirmation); provided, however, that in the case of a resigning
or terminated Special Servicer, such appointment shall be subject to the rights
of the Holders of Certificates evidencing a majority of the Voting Rights
allocated to the Controlling Class to designate a successor pursuant to Section
6.09. Except with respect to an appointment provided below, no appointment of a
successor to the Master Servicer or the Special Servicer hereunder shall be
effective until the assumption of the successor to such party of all its
responsibilities, duties and liabilities under this Agreement. Pending
appointment of a successor to the Master Servicer or the Special Servicer
hereunder, the Trustee shall act in such capacity as hereinabove provided.
Notwithstanding the above, the Trustee shall, if the Master Servicer is the
resigning or terminated party and the Trustee is prohibited by law or regulation
from making P&I Advances, promptly appoint any established mortgage loan
servicing institution that has a net worth of not less than $15,000,000 and is
otherwise acceptable to each Rating Agency (as evidenced by written confirmation
therefrom to the effect that the appointment of such institution would not cause
the qualification, downgrading or withdrawal of the then current rating on any
Class of Certificates), as the successor to the Master Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Master Servicer hereunder (including, without limitation, the obligation to
make P&I Advances), which appointment will become effective immediately. In
connection with any such appointment and assumption described herein, the
Trustee may make such arrangements for the compensation of such successor out of
payments on the Mortgage Loans as it and such successor shall agree; provided,
however, that no such compensation shall be in excess of that permitted the
resigning or terminated party hereunder. Such successor and the other parties
hereto shall take such action, consistent with this Agreement, as shall be
necessary to effectuate any such succession.

            Section 7.03 Notification to Certificateholders and Companion
Holders.

            (a) Upon any resignation of the Master Servicer or the Special
Servicer pursuant to Section 6.04, any termination of the Master Servicer or the
Special Servicer pursuant to Section 7.01, any appointment of a successor to the
Master Servicer or the Special Servicer pursuant to Section 7.02 or the
effectiveness of any designation of a new Special Servicer pursuant to Section
6.09, the Trustee shall give prompt written notice thereof to Certificateholders
at their respective addresses appearing in the Certificate Register, and to the
Companion Holders.

            (b) Not later than the later of (i) 60 days after the occurrence of
any event which constitutes or, with notice or lapse of time or both, would
constitute an Event of Default and (ii) five days after a Responsible Officer of
the Trustee has notice of the occurrence of such an event, the Trustee shall
transmit by mail to the Depositor, all Certificateholders, the Rating Agencies
and the Companion Holders notice of such occurrence, unless such default shall
have been cured.

            Section 7.04 Waiver of Events of Default.

            The Holders representing at least 66-2/3% of the Voting Rights
allocated to the Classes of Certificates affected by any Event of Default
hereunder may waive such Event of Default; provided, however, that an Event of
Default under clause (i), (ii), (x), (xi) or (xii) of Section 7.01(a) may be
waived only by all of the Certificateholders of the affected Classes. Upon any
such waiver of an Event of Default, such Event of Default shall cease to exist
and shall be deemed to have been remedied for every purpose hereunder. No such
waiver shall extend to any subsequent or other Event of Default or impair any
right consequent thereon except to the extent expressly so waived.
Notwithstanding any other provisions of this Agreement, for purposes of waiving
any Event of Default pursuant to this Section 7.04, Certificates registered in
the name of the Depositor or any Affiliate of the Depositor shall be entitled to
Voting Rights with respect to the matters described above.

            Section 7.05 Additional Remedies of Trustee Upon Event of Default.

            During the continuance of any Event of Default, so long as such
Event of Default shall not have been remedied, the Trustee, in addition to the
rights specified in Section 7.01, shall have the right, in its own name and as
trustee of an express trust, to take all actions now or hereafter existing at
law, in equity or by statute to enforce its rights and remedies and to protect
the interests, and enforce the rights and remedies, of the Certificateholders
(including the institution and prosecution of all judicial, administrative and
other proceedings and the filings of proofs of claim and debt in connection
therewith). No remedy provided for by this Agreement shall be exclusive of any
other remedy, and each and every remedy shall be cumulative and in addition to
any other remedy, and no delay or omission to exercise any right or remedy shall
impair any such right or remedy or shall be deemed to be a waiver of any Event
of Default. Under no circumstances shall the rights provided to the Trustee
under this Section 7.05 be construed as a duty or obligation of the Trustee.

                                  ARTICLE VIII

                     CONCERNING THE TRUSTEE AND FISCAL AGENT

            Section 8.01 Duties of Trustee.

            (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. If an Event of Default occurs and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Agreement, and use the same degree of care and skill in their exercise as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs. Any permissive right of the Trustee contained in this Agreement
shall not be construed as a duty.

            (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee that are specifically required to be furnished pursuant to any
provision of this Agreement (other than the Mortgage Files, the review of which
is specifically governed by the terms of Article II), shall examine them to
determine whether they conform to the requirements of this Agreement to the
extent specifically set forth herein. If any such instrument is found not to
conform to the requirements of this Agreement in a material manner, the Trustee
shall take such action as it deems appropriate to have the instrument corrected.
The Trustee shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Depositor or the Master Servicer or the Special
Servicer, and accepted by the Trustee in good faith, pursuant to this Agreement.

            (c) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own misconduct; provided, however, that:

            (i) Prior to the occurrence of an Event of Default, and after the
      curing of all such Events of Default which may have occurred, the duties
      and obligations of the Trustee shall be determined solely by the express
      provisions of this Agreement, the Trustee shall not be liable except for
      the performance of such duties and obligations as are specifically set
      forth in this Agreement, no implied covenants or obligations shall be read
      into this Agreement against the Trustee and, in the absence of bad faith
      on the part of the Trustee, the Trustee may conclusively rely, as to the
      truth of the statements and the correctness of the opinions expressed
      therein, upon any certificates or opinions furnished to the Trustee and
      conforming to the requirements of this Agreement;

            (ii) The Trustee shall not be personally liable for an error of
      judgment made in good faith by a Responsible Officer or Responsible
      Officers of the Trustee unless it shall be proved that the Trustee was
      negligent in ascertaining the pertinent facts if it was required to do so;

            (iii) The Trustee shall not be personally liable with respect to any
      action taken, suffered or omitted to be taken by it in good faith in
      accordance with the direction of Holders of Certificates entitled to at
      least 25% of the Voting Rights relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee or
      exercising any trust or power conferred upon the Trustee under this
      Agreement; and

            (iv) The protections, immunities and indemnities afforded to the
      Trustee hereunder shall also be available to the Paying Agent,
      Authenticating Agent, Certificate Registrar, REMIC Administrator and
      Custodian.

            Section 8.02 Certain Matters Affecting Trustee.

            Except as otherwise provided in Section 8.01 and Article X:

            (a) the Trustee may rely upon and shall be protected in acting or
refraining from acting upon any resolution, Officer's Certificate, certificate
of auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond or other paper or document
reasonably believed by it to be genuine and to have been signed or presented by
the proper party or parties;

            (b) the Trustee may consult with counsel and the written advice of
such counsel or any Opinion of Counsel shall be full and complete authorization
and protection in respect of any action taken or suffered or omitted by it
hereunder in good faith and in accordance therewith;

            (c) the Trustee shall be under no obligation to exercise any of the
trusts or powers vested in it by this Agreement or to make any investigation of
matters arising hereunder or, except as provided in Section 10.01 or 10.02, to
institute, conduct or defend any litigation hereunder or in relation hereto at
the request, order or direction of any of the Certificateholders, pursuant to
the provisions of this Agreement, unless such Certificateholders shall have
offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby; the Trustee
shall be under no obligation to take any action to enforce the rights of the
Trust Fund under the applicable Swap Contract unless it is assured, in its sole
discretion, that reasonable security and indemnity against the costs and
expenses of such action(s) will be offered by the applicable Swap Counterparty,
the Holders of the Class A-3SF Certificates and the Holders of the Class A-MFL
Certificates, as applicable, or any other party (other than the Trust Fund); the
Trustee shall not be required to expend or risk its own funds or otherwise incur
any financial liability in the performance of any of its duties hereunder, or in
the exercise of any of its rights or powers, if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it; provided, however, that
nothing contained herein shall, relieve the Trustee of the obligation, upon the
occurrence of an Event of Default which has not been cured, to exercise such of
the rights and powers vested in it by this Agreement, and to use the same degree
of care and skill in their exercise as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs;

            (d) the Trustee shall not be personally liable for any action
reasonably taken, suffered or omitted by it in good faith and believed by it to
be authorized or within the discretion or rights or powers conferred upon it by
this Agreement;

            (e) prior to the occurrence of an Event of Default hereunder and
after the curing of all Events of Default which may have occurred, the Trustee
shall not be bound to make any investigation into the facts or matters stated in
any resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, approval, bond or other paper or document, unless
requested in writing to do so by Holders of Certificates entitled to at least
25% of the Voting Rights; provided, however, that if the payment within a
reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, not reasonably assured to the Trustee by the security afforded to it by
the terms of this Agreement, the Trustee may require reasonable indemnity
against such expense or liability as a condition to taking any such action;

            (f) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys; provided, however, that the Trustee shall remain responsible for all
acts and omissions of such agents or attorneys within the scope of their
employment to the same extent as it is responsible for its own actions and
omissions hereunder;

            (g) the Trustee shall not be responsible for any act or omission of
the Master Servicer or the Special Servicer (unless the Trustee is acting as
Master Servicer or the Special Servicer) or the Depositor; and

            (h) neither the Trustee nor the Certificate Registrar shall have any
obligation or duty to monitor, determine or inquire as to compliance with any
restriction on transfer imposed under Article V under this Agreement or under
applicable law with respect to any transfer of any Certificate or any interest
therein, other than to require delivery of the certification(s) and/or Opinions
of Counsel described in said Article applicable with respect to changes in
registration of record ownership of Certificates in the Certificate Register and
to examine the same to determine substantial compliance with the express
requirements of this Agreement. The Trustee and Certificate Registrar shall have
no liability for transfers, including transfers made through the book entry
facilities of the Depository or between or among Depository Participants or
beneficial owners of the Certificates, made in violation of applicable
restrictions except for its failure to perform its express duties in connection
with changes in registration of record ownership in the Certificate Register.

            Section 8.03 Trustee and Fiscal Agent Not Liable for Validity or
Sufficiency of Certificates or Mortgage Loans.

            The recitals contained herein and in the Certificates, other than
the statements attributed to the Trustee and the Fiscal Agent in Article II,
Section 8.15 and Section 8.20 and the signature of the Certificate Registrar and
the Authenticating Agent set forth on each outstanding Certificate, shall be
taken as the statements of the Depositor, the Master Servicer or the Special
Servicer, as the case may be, and neither the Trustee nor the Fiscal Agent
assume any responsibility for their correctness. Except as set forth in Section
8.15 and Section 8.20, the Trustee and the Fiscal Agent make no representations
as to the validity or sufficiency of this Agreement or of any Certificate (other
than as to the signature of the Trustee set forth thereon) or of any Mortgage
Loan or related document. The Trustee and the Fiscal Agent shall not be
accountable for the use or application by the Depositor of any of the
Certificates issued to it or of the proceeds of such Certificates, or for the
use or application of any funds paid to the Depositor in respect of the
assignment of the Mortgage Loans to the Trust Fund, or any funds deposited in or
withdrawn from the Certificate Account or any other account by or on behalf of
the Depositor, the Master Servicer or the Special Servicer unless the Trustee is
acting as Paying Agent. The Trustee and the Fiscal Agent shall not be
responsible for the accuracy or content of any resolution, certificate,
statement, opinion, report, document, order or other instrument furnished by the
Depositor, the Master Servicer or the Special Servicer, and accepted by the
Trustee in good faith, pursuant to this Agreement.

            Section 8.04 Trustee and Fiscal Agent May Own Certificates.

            The Trustee, the Fiscal Agent or any agent of the Trustee or the
Fiscal Agent in its individual or any other capacity, may become the owner or
pledgee of Certificates with the same rights (except as otherwise provided in
the definition of "Certificateholder") as it would have if it were not the
Trustee, the Fiscal Agent or such agent.

            Section 8.05 Fees and Expenses of Trustee; Indemnification of
Trustee.

            (a) On each Distribution Date, the Trustee shall withdraw from the
general funds on deposit in the Distribution Account as provided in Section
3.05(b), prior to any distributions to be made therefrom on such date, and pay
to itself all earned but unpaid Trustee Fees, as compensation for all services
rendered by the Trustee, in the execution of the trusts hereby created and in
the exercise and performance of any of the powers and duties of the Trustee
hereunder at the Trustee Fee Rate. No Trustee Fee shall be payable with respect
to the Companion Loans. The Trustee Fee (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
shall constitute the Trustee's sole compensation for such services to be
rendered by it.

            (b) The Trustee and any director, officer, employee, affiliate,
agent or "control" person within the meaning of the Securities Act of 1933 of
the Trustee shall be entitled to be indemnified for and held harmless by the
Trust Fund against any loss, liability or reasonable "out-of-pocket" expense
(including, without limitation, costs and expenses of litigation, and of
investigation, counsel fees, damages, judgments and amounts paid in settlement)
arising out of, or incurred in connection with this Agreement, the Mortgage
Loans or the Certificates or any act of the Master Servicer or the Special
Servicer taken on behalf of the Trustee as provided for herein; provided that
such expense is an "unanticipated expense incurred by the REMIC" within the
meaning of Treasury Regulations Section 1.860G-1(b)(3)(ii); provided, further,
that neither the Trustee, nor any of the other above specified Persons shall be
entitled to indemnification pursuant to this Section 8.05(b) for (1) any
liability specifically required to be borne thereby pursuant to the terms
hereof, or (2) any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of the Trustee's
obligations and duties hereunder, or by reason of its negligent disregard of
such obligations and duties, or as may arise from a breach of any
representation, warranty or covenant of the Trustee, as applicable, made herein.
The provisions of this Section 8.05(b) shall survive any resignation or removal
of the Trustee and appointment of a successor Trustee.

            Section 8.06 Eligibility Requirements for Trustee.

            The Trustee hereunder shall at all times be an association or a
corporation organized and doing business under the laws of the United States of
America or any State thereof or the District of Columbia, authorized under such
laws to exercise trust powers, having a combined capital and surplus of at least
$100,000,000 and subject to supervision or examination by a federal or state
banking authority. If such association or corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such association or corporation
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published. The Trustee shall also be an entity
with a long term unsecured debt rating of at least "A+" by Fitch, "A+" by S&P
and "Aa3" by Moody's and a short term unsecured debt rating of at least "F1" by
Fitch and "A-1" by S&P, (b) "A-" from S&P, if a Fiscal Agent meeting the
requirements of Section 8.19(a) is then currently acting in such capacity, or
(c) such other rating that shall not result in the qualification, downgrading or
withdrawal of the rating or ratings assigned to one or more Classes of the
Certificates by any Rating Agency as confirmed in writing. In case at any time
the Trustee shall cease to be eligible in accordance with the provisions of this
Section, the Trustee, shall resign immediately in the manner and with the effect
specified in Section 8.07; provided that if the Trustee shall cease to be so
eligible because its combined capital and surplus is no longer at least
$100,000,000 or its long-term unsecured debt rating no longer conforms to the
requirements of the immediately preceding sentence, and if the Trustee proposes
to the other parties hereto to enter into an agreement with (and reasonably
acceptable to) each of them, and if in light of such agreement the Trustee's
continuing to act in such capacity would not (as evidenced in writing by each
Rating Agency) cause any Rating Agency to qualify, downgrade or withdraw any
rating assigned thereby to any Class of Certificates, then upon the execution
and delivery of such agreement the Trustee shall not be required to resign, and
may continue in such capacity, for so long as none of the ratings assigned by
the Rating Agencies to the Certificates is qualified, downgraded or withdrawn
thereby. The bank, trust company, corporation or association serving as Trustee
may have normal banking and trust relationships with the Depositor, the Master
Servicer, the Special Servicer and their respective Affiliates but, except to
the extent permitted or required by Section 7.02, shall not be an "Affiliate"
(as such term is defined in Section III of PTE 2000-58) of the Master Servicer,
the Special Servicer, any sub-servicer, the Underwriters, the Depositor, or any
obligor with respect to Mortgage Loans constituting more than 5.0% of the
aggregate authorized principal balance of the Mortgage Loans as of the date of
the initial issuances of the Certificates or any "Affiliate" (as such term is
defined in Section III of PTE 2000-58) of any such Person.

            Section 8.07 Resignation and Removal of Trustee.

            (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Master Servicer, the Special Servicer, the Class A-3SF Swap Counterparty, the
Class A-MFL Swap Counterparty and to all Certificateholders at their respective
addresses set forth in the Certificate Register. Upon receiving such notice of
resignation, the Master Servicer shall promptly appoint a successor trustee
meeting the requirements in Section 8.06 and acceptable to the Depositor and the
Rating Agencies by written instrument, in duplicate, which instrument shall be
delivered to the resigning Trustee and to the successor trustee. A copy of such
instrument shall be delivered to the Depositor, the Special Servicer, the Class
A-3SF Swap Counterparty, the Class A-MFL Swap Counterparty and the
Certificateholders by the Master Servicer. If no successor trustee shall have
been so appointed and have accepted appointment within 30 days after the giving
of such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor trustee.

            (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor or the Master Servicer, or if at any
time the Trustee shall become incapable of acting, or shall be adjudged bankrupt
or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, or if the Trustee or Paying Agent (if different from the Trustee)
shall fail (other than by reason of the failure of either the Master Servicer or
the Special Servicer to timely perform its obligations hereunder or as a result
of other circumstances beyond the Trustee's reasonable control), to timely
deliver any report to be delivered by the Trustee pursuant to Section 4.02 and
such failure shall continue unremedied for a period of five days, or if the
Trustee or Paying Agent (if different from the Trustee) fails to make
distributions required pursuant to Section 3.05(b), 4.01 or 9.01, then the
Depositor may remove the Trustee and appoint a successor trustee if necessary,
acceptable to the Master Servicer and the Rating Agencies (as evidenced by
written confirmation therefrom to the effect that the appointment of such
institution would not cause the qualification, downgrading or withdrawal of the
then-current rating on any Class of Certificates) by written instrument, in
duplicate, which instrument shall be delivered to the Trustee so removed and to
the successor trustee. A copy of such instrument shall be delivered to the
Master Servicer, the Special Servicer and the Certificateholders by the
Depositor.

            (c) The Holders of Certificates entitled to at least 51% of the
Voting Rights may at any time remove the Trustee and appoint a successor
trustee, if necessary, by written instrument or instruments, in triplicate,
signed by such Holders or their attorneys-in-fact duly authorized, one complete
set of which instruments shall be delivered to the Master Servicer, one complete
set to the Trustee so removed and one complete set to the successor trustee so
appointed. A copy of such instrument shall be delivered to the Depositor, the
Special Servicer and the remaining Certificateholders by the successor so
appointed. In the event that the Trustee is terminated or removed pursuant to
this Section 8.07, all of its and any corresponding Fiscal Agent's rights and
obligations under this Agreement and in and to the Mortgage Loans shall be
terminated, other than any rights or obligations that accrued prior to the date
of such termination or removal (including the right to receive all fees,
expenses and other amounts (including, without limitation, P&I Advances and
accrued interest thereon) accrued or owing to it under this Agreement, with
respect to periods prior to the date of such termination or removal and no
termination without cause shall be effective until the payment of such amounts
to the Trustee and such Fiscal Agent).

            (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08.

            Section 8.08 Successor Trustee.

            (a) Any successor trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor, the Master Servicer,
the Special Servicer and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein. The predecessor trustee
shall deliver to the successor trustee all Mortgage Files and related documents
and statements held by it hereunder (other than any Mortgage Files at the time
held on its behalf by a third-party Custodian, which Custodian shall become the
agent of the successor trustee), and the Depositor, the Master Servicer, the
Special Servicer and the predecessor trustee shall execute and deliver such
instruments and do such other things as may reasonably be required to more fully
and certainly vest and confirm in the successor trustee all such rights, powers,
duties and obligations, and to enable the successor trustee to perform its
obligations hereunder.

            (b) No successor trustee shall accept appointment as provided in
this Section 8.08, unless at the time of such acceptance such successor trustee
shall be eligible under the provisions of Section 8.06 and the Rating Agencies
have provided confirmation pursuant to such Section.

            (c) Upon acceptance of appointment by a successor trustee as
provided in this Section 8.08, such successor trustee shall mail notice of the
succession of such trustee hereunder to the Depositor and the
Certificateholders.

            Section 8.09 Merger or Consolidation of Trustee and Fiscal Agent.

            Any entity into which the Trustee or the Fiscal Agent may be merged
or converted or with which the Trustee or the Fiscal Agent may be consolidated
or any entity resulting from any merger, conversion or consolidation to which
the Trustee or the Fiscal Agent shall be a party, or any entity succeeding to
the corporate trust business of the Trustee or the Fiscal Agent, shall be the
successor of the Trustee or the Fiscal Agent, as the case may be, hereunder;
provided such entity shall be eligible under the provisions of Section 8.06 and
the Rating Agencies have provided confirmation pursuant to such Section, without
the execution or filing of any paper or any further act on the part of any of
the parties hereto, anything herein to the contrary notwithstanding.

            Section 8.10 Appointment of Co-Trustee or Separate Trustee.

            (a) Notwithstanding any other provisions hereof, at any time, for
the purpose of meeting any legal requirements of any jurisdiction in which any
part of the Trust Fund or property securing the same may at the time be located,
the Master Servicer and the Trustee acting jointly shall have the power and
shall execute and deliver all instruments to appoint one or more Persons
approved by the Trustee to act as co-trustee or co-trustees, jointly with the
Trustee, or separate trustee or separate trustees, of all or any part of the
Trust Fund, and to vest in such Person or Persons, in such capacity, such title
to the Trust Fund, or any part thereof, and, subject to the other provisions of
this Section 8.10, such powers, duties, obligations, rights and trusts as the
Master Servicer and the Trustee may consider necessary or desirable. If the
Master Servicer shall not have joined in such appointment within 15 days after
the receipt by it of a request to do so, or in case an Event of Default in
respect of the Master Servicer shall have occurred and be continuing, the
Trustee alone shall have the power to make such appointment. No co-trustee or
separate trustee hereunder shall be required to meet the terms of eligibility as
a successor trustee under Section 8.06 hereunder and no notice to Holders of
Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be
required under Section 8.08 hereof.

            (b) In the case of any appointment of a co-trustee or separate
trustee pursuant to this Section 8.10, all rights, powers, duties and
obligations conferred or imposed upon the Trustee shall be conferred or imposed
upon and exercised or performed by the Trustee and such separate trustee or
co-trustee jointly, except to the extent that under any law of any jurisdiction
in which any particular act or acts are to be performed (whether as Trustee
hereunder or as successor to the Master Servicer or the Special Servicer
hereunder), the Trustee shall be incompetent or unqualified to perform such act
or acts, in which event such rights, powers, duties and obligations (including
the holding of title to the Trust Fund or any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

            (c) Any notice, request or other writing given to the Trustee shall
be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement and
the conditions of this Article VIII. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or
property specified in its instrument of appointment, either jointly with the
Trustee or separately, as may be provided therein, subject to all the provisions
of this Agreement, specifically including every provision of this Agreement
relating to the conduct of, affecting the liability of, or affording protection
to, the Trustee. Every such instrument shall be filed with the Trustee.

            (d) Any separate trustee or co-trustee may, at any time, constitute
the Trustee, its agent or attorney-in-fact, with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect of
this Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall cease to exist, become incapable of acting, resign or be
removed, all of its estates, properties, rights, remedies and trusts shall vest
in and be exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

            (e) The appointment of a co-trustee or separate trustee under this
Section 8.10 shall not relieve the Trustee of its duties and responsibilities
hereunder.

            Section 8.11 Appointment of Custodians.

            The Trustee may appoint at the Trustee's expense one or more
Custodians to hold all or a portion of the Mortgage Files as agent for the
Trustee. Each Custodian shall be a depository institution supervised and
regulated by a federal or state banking authority, shall have combined capital
and surplus of at least $10,000,000, shall be qualified to do business in the
jurisdiction in which it holds any Mortgage File and shall not be the Depositor,
any Mortgage Loan Seller or any Affiliate of the Depositor or any Mortgage Loan
Seller. Neither the Master Servicer nor the Special Servicer shall have any duty
to verify that any such Custodian is qualified to act as such in accordance with
the preceding sentence. Any such appointment of a third party Custodian and the
acceptance thereof shall be pursuant to a written agreement, which written
agreement shall (i) be consistent with this Agreement in all material respects
and requires the Custodian to comply with this Agreement in all material
respects and requires the Custodian to comply with all of the applicable
conditions of this Agreement; (ii) provide that if the Trustee shall for any
reason no longer act in the capacity of Trustee hereunder (including, without
limitation, by reason of an Event of Default), the successor trustee or its
designee may thereupon assume all of the rights and, except to the extent such
obligations arose prior to the date of assumption, obligations of the Custodian
under such agreement or alternatively, may terminate such agreement without
cause and without payment of any penalty or termination fee; and (iii) not

assets of the Trust Fund. The appointment of one or more Custodians shall not
relieve the Trustee from any of its obligations hereunder, and the Trustee shall
remain responsible and liable for all acts and omissions of any Custodian. The
initial Custodian shall be the Trustee. Notwithstanding anything herein to the
contrary, if the Trustee is no longer the Custodian, any provision or
requirement herein requiring notice or any information or documentation to be
provided to the Custodian shall be construed to require that such notice,
information or documents also be provided to the Trustee. Any Custodian
hereunder (other than the Trustee) shall at all times maintain a fidelity bond
and errors and omissions policy in amounts customary for custodians performing
duties similar to those set forth in this Agreement.

Affiliate thereof. In the absence of any other Person appointed in accordance
herewith acting as Authenticating Agent, the Trustee hereby agrees to act in
such capacity in accordance with the terms hereof. Notwithstanding anything
herein to the contrary, if the Trustee is no longer the Authenticating Agent,
any provision or requirement herein requiring notice or any information or
documentation to be provided to the Authenticating Agent shall be construed to
require that such notice, information or documentation also be provided to the
Trustee.

notice of such appointment to the Master Servicer, the Certificate Registrar and
the Depositor and shall mail notice of such appointment to all Holders of

successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers, duties and responsibilities of
its predecessor hereunder, with like effect as if originally named as

liability for any action taken by it as such at the direction of the Trustee.

with the consent of the Depositor and at the cost of the requesting Party, the
Trustee shall provide copies of such documentation to the Depositor, any
Certificateholder and to the OTS, the FDIC and any other bank or insurance
regulatory authority that may exercise authority over any Certificateholder.

            Section 8.14 Appointment of REMIC Administrators.

            (a) The Trustee may appoint at the Trustee's expense, one or more
REMIC Administrators, which shall be authorized to act on behalf of the Trustee
in performing the functions set forth in Sections 3.17, 10.01 and 10.02 herein.
The Trustee shall cause any such REMIC Administrator to execute and deliver to

hereof. If LaSalle Bank National Association is removed as Trustee, then LaSalle
Bank National Association shall be terminated as REMIC Administrator.

party, or any Person succeeding to the corporate agency business of any REMIC
Administrator, shall continue to be the REMIC Administrator without the
execution or filing of any paper or any further act on the part of the Trustee
or the REMIC Administrator.

            (c) Any REMIC Administrator may at any time resign by giving at
least 30 days' advance written notice of resignation to the Trustee the

and the Depositor. The Trustee may at any time terminate the agency of any REMIC

the provisions of this Section 8.14, the Trustee may appoint a successor REMIC
Administrator, in which case the Trustee shall given written notice of such
appointment to the Master Servicer and the Depositor and shall mail notice of
such appointment to all Holders of Certificates; provided, however, that no

provisions of this Section 8.14. Any successor REMIC Administrator upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as REMIC Administrator. No REMIC Administrator
shall have responsibility or liability for any action taken by it as such at the
direction of the Trustee.

            Section 8.15 Representations and Warranties of Trustee.

            The Trustee hereby represents and warrants to the Master Servicer,
the Special Servicer, the Depositor and the Fiscal Agent and for the benefit of
the Certificateholders, as of the Closing Date, that:

            (i) The Trustee is a national banking association duly organized,
      validly existing and in good standing under the laws of the United States.

            (ii) The execution and delivery of this Agreement by the Trustee,
      and the performance and compliance with the terms of this Agreement by the
      Trustee, will not violate the Trustee's organizational documents or
      constitute a default (or an event which, with notice or lapse of time, or
      both, would constitute a default) under, or result in a material breach
      of, any material agreement or other material instrument to which it is a
      party or by which it is bound.

            (iii) Except to the extent that the laws of certain jurisdictions in
      which any part of the Trust Fund may be located require that a co-trustee
      or separate trustee be appointed to act with respect to such property as
      contemplated by Section 8.10, the Trustee has the full power and authority
      to carry on its business as now being conducted and to enter into and
      consummate all transactions contemplated by this Agreement, has duly
      authorized the execution, delivery and performance of this Agreement, and
      has duly executed and delivered this Agreement.

            (iv) This Agreement, assuming due authorization, execution and
      delivery by the other parties hereto, constitutes a valid, legal and
      binding obligation of the Trustee, enforceable against the Trustee in
      accordance with the terms hereof (including with respect to any advancing
      obligations hereunder), subject to (A) applicable bankruptcy, insolvency,
      reorganization, moratorium and other laws affecting the enforcement of
      creditors' rights generally and the rights of creditors of banks, and (B)
      general principles of equity, regardless of whether such enforcement is
      considered in a proceeding in equity or at law.

            (v) The Trustee is not in violation of, and its execution and
      delivery of this Agreement and its performance and compliance with the
      terms of this Agreement will not constitute a violation of, any law, any
      order or decree of any court or arbiter, or any order, regulation or
      demand of any federal, state or local governmental or regulatory
      authority, which violation, in the Trustee's good faith and reasonable
      judgment, is likely to affect materially and adversely the ability of the
      Trustee to perform its obligations under this Agreement.

            (vi) No litigation is pending or, to the best of the Trustee's
      knowledge, threatened against the Trustee that, if determined adversely to
      the Trustee, would prohibit the Trustee from entering into this Agreement
      or, in the Trustee's good faith and reasonable judgment, is likely to
      materially and adversely affect the ability of the Trustee to perform its
      obligations under this Agreement.

            (vii) Any consent, approval, authorization or order of any court or
      governmental agency or body required for the execution, delivery and
      performance by the Trustee of or compliance by the Trustee with this
      Agreement or the consummation of the transactions contemplated by this
      Agreement has been obtained and is effective.

            Section 8.16 Appointment of the Paying Agent.

            The Trustee may appoint a Paying Agent for the purpose of making
distributions to Certificateholders hereunder. The Trustee shall cause such
Paying Agent to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee that such Paying Agent will hold all
sums held by it for the payment to Certificateholders in an Eligible Account in
trust for the benefit of the Certificateholders entitled thereto until such sums
shall be paid to the Certificateholders. All funds remitted by the Trustee or
the Master Servicer to any such Paying Agent for the purpose of making
distributions shall be paid to Certificateholders on each Distribution Date and
any amounts not so paid shall be returned on such Distribution Date to the
Trustee or the Master Servicer, as applicable. Any Paying Agent shall be either
a bank or a trust company or otherwise authorized under law to exercise
corporate trust powers and shall have a short-term debt rating of at least "A-1"
and a long-term debt rating of at least "A-" by S&P, "A-" by Fitch or a rating
of at least "A2" (or its equivalent) by Moody's or such lower rating as will not
result in qualification, downgrading or withdrawal of the ratings then assigned
to the Certificates, as evidenced in writing by the Rating Agencies. Any such
appointment of a third party Paying Agent and the acceptance thereof shall be
pursuant to a written agreement, which written agreement shall (i) be consistent
with this Agreement in all material respects and requires the Paying Agent to
comply with this Agreement in all material respects and requires the Paying
Agent to comply with all of the applicable conditions of this Agreement; (ii)
provide that if the Trustee shall for any reason no longer act in the capacity
of Trustee hereunder (including, without limitation, by reason of an Event of
Default), the successor trustee or its designee may (A) thereupon assume all of
the rights and, except to the extent they arose prior to the date of assumption,
obligations of the Paying Agent under such agreement or (B) terminate such
agreement without cause and without payment of any penalty or termination fee;
and (iii) not permit the Paying Agent any rights or indemnification that may be
satisfied out of assets of the Trust Fund. The appointment of any Paying Agent
shall not relieve the Trustee from any of its obligations hereunder, and the
Trustee shall remain responsible and liable for all acts and omissions of any
Paying Agent to the extent such Paying Agent would have been responsible
pursuant to the terms hereof. The initial Paying Agent shall be the Trustee.
Notwithstanding anything herein to the contrary, if the Trustee is no longer the
Paying Agent, any provision or requirement herein requiring notice or any
information to be provided to the Paying Agent shall be construed to require
that such notice, information or documentation also be provided to the Trustee.
If the Trustee appoints a Paying Agent other than the Trustee, the Trustee shall
promptly notify the Master Servicer of such appointment and give to the Master
Servicer the Paying Agent's wiring instructions and notice address.

            Section 8.17 Reports to the Securities and Exchange Commission;
Available Information.

            (a) The Trustee the Master Servicer and the Special Servicer shall
reasonably cooperate with the Depositor in connection with the Trust Fund's
satisfying the reporting requirements under the Exchange Act. The Trustee shall
prepare on behalf of the Trust Fund any Forms 8-K and 10-K customary for similar
securities as required by the Exchange Act and the rules and regulations of the
Commission thereunder, and the Trustee shall sign and file (via EDGAR) such
Forms on behalf of the Depositor, until directed in writing by the Depositor to
discontinue such filings. The Depositor hereby grants to the Trustee a limited
power of attorney to execute and file each such document on behalf of the
Depositor. Such power of attorney shall continue until the earlier of either (i)
receipt by the Trustee from the Depositor of written termination of such power
of attorney and (ii) the termination of the Trust Fund. Notwithstanding the
foregoing, in the event that the Commission does not accept a Certification
signed by the Depositor where the related Form 10-K is signed by the Trustee on
behalf of the Depositor, the Trustee shall prepare such Form 10-K to be signed
by the Depositor and the Depositor shall sign such form.

            (b) A Form 8-K shall be filed by the Trustee within 15 days after
each Distribution Date, including a copy of the Distribution Date Statement for
such Distribution Date as an exhibit thereto. Prior to March 30th of each year
(or such earlier date as may be required by the Exchange Act and the Rules and
Regulations of the Commission), the Trustee shall file a Form 10-K, in substance
as required by applicable law or applicable Commission staff's interpretations.
Such Form 10-K shall include as exhibits the Master Servicer's and the Special
Servicer's annual statement of compliance described under Section 3.13 and the
accountant's report described under Section 3.14, in each case to the extent
they have been timely delivered to the Trustee. If they are not so timely
delivered, the Trustee shall file an amended Form 10-K including such documents
as exhibits reasonably promptly after they are delivered to the Trustee. The
Trustee shall have no liability with respect to any failure to properly prepare
or file such periodic reports resulting from or relating to the Trustee's
inability or failure to obtain any information not resulting from its own
negligence, willful misconduct or bad faith. The Form 10-K shall also include a
certification in the form attached hereto as Exhibit P (the "Certification"),
which shall, except as described below, be signed by the senior officer of the
Depositor in charge of securitization. Notwithstanding the foregoing, if the
Commission determines that the Certification may be executed by multiple
Persons, the Trustee shall sign the Certification, subject to the succeeding
paragraph and Section 8.17(d) through 8.17(f), in respect of items 1 through 3
thereof, the Master Servicer shall cause its respective senior officers in
charge of servicing to sign the Certification in respect of items 4 and 5
thereof to the extent such items relate to the duties and actions of the Master
Servicer, and the Special Servicer shall cause its respective senior officers in
charge of servicing to sign the Certification in respect of items 4 and 5
thereof to the extent such items relate to the duties and actions of the Special
Servicer, and the Trustee may rely on the Certification signed by the Master
Servicer and Special Servicer to the same extent as provided in Section 8.17(c)
below. The Master Servicer may rely on the Certification signed by the Special
Servicer to the same extent as provided in Section 8.17(c) below.

            In the event the Commission determines that the Certification may be
executed by multiple Persons, and with respect to the Trustee's obligation in
the preceding paragraph to sign the Certification in respect of item 3, the
Trustee's obligation to sign such Certification shall be conditioned upon the
Trustee and the Depositor entering into an agreement with respect to the payment
of a reasonable additional fee for the reasonable costs and expenses necessary
for the Trustee to sign such Certification; provided that in no event shall such
fee exceed $15,000 annually. In the event that such agreement is not reached,
the Depositor may continue to sign the portion of the Certification which the
Trustee does not sign.

            Although it is the parties' intent that compliance by the parties
with provisions of this Section 8.17 will constitute compliance with the review
and certifications required by Section 302(a) of the Sarbanes-Oxley Act (the
"Section 302 Requirements") or other applicable law, or the interpretation
thereof by the Commission's staff (including the issuance of additional guidance
by such staff), if it is determined that additional or modified procedures are
required, or, similarly, to the extent that certain certifications or procedures
are not required, the parties hereto agree to negotiate in good faith to modify
the provisions of this Section 8.17 to comply with such change or additional
guidance. Notwithstanding any other provision herein, no consent of any
Certificateholder shall be required to make any such modification or amendment
to this Section 8.17 to make such changes as are described above. In addition,
in no event shall the provisions set forth in this Section 8.17(b) limit the
ability of, or impose an obligation on, the Trustee, the Fiscal Agent, the
Master Servicer or the Special Servicer to conduct additional investigations
determined by it to be necessary or appropriate (in accordance with the written
advice of counsel) to comply with the Section 302 Requirements.

            (c) In the event the Certification is to be signed by an officer of
the Depositor, the Trustee shall sign a certification (in the form attached
hereto as Exhibit Q) for the benefit of the Depositor and its officers,
directors and Affiliates (provided, however, that the Trustee shall not
undertake an analysis of the accountant's report attached as an exhibit to the
Form 10-K), and the Master Servicer shall sign a certification (in the form
attached hereto as Exhibit R-1) for the benefit of the Depositor and its
officers, directors and Affiliates, and the Special Servicer shall sign a
certification (in the form attached hereto as Exhibit R-2) for the benefit of
the Depositor and the Master Servicer and their officers, directors and
Affiliates. Each such certification shall be delivered to the Depositor, the
Trustee and the Master Servicer, if applicable, by March 15th of each year (or
if not a Business Day, the immediately preceding Business Day). The
Certification attached hereto as Exhibit Q shall be delivered to the Trustee for
filing by March 20th of each year (or if not a Business Day, the immediately
preceding Business Day). In addition, (i) the Trustee shall indemnify and hold
harmless the Depositor and its officers, directors and Affiliates from and
against any losses, damages, penalties, fines, forfeitures, reasonable and
necessary legal fees and related costs, judgments and other costs and expenses
arising out of or based upon a breach of the Trustee's obligations under this
Section 8.17 or the Trustee's negligence, bad faith or willful misconduct in
connection therewith, and (ii) the Master Servicer and Special Servicer shall
each severally and not jointly indemnify and hold harmless the Depositor, the
Trustee and, in the case of the Special Servicer, the Master Servicer, and their
respective officers, directors and Affiliates from and against any losses,
damages, penalties, fines, forfeitures, reasonable and necessary legal fees and
related costs, judgments and other costs and expenses arising out of or based
upon a breach of the Master Servicer's or Special Servicer's obligations, as the
case may be, under this Section 8.17 or the negligence, bad faith or willful
misconduct of the Master Servicer or the Special Servicer, as the case may be,
in connection therewith. If the indemnification provided for herein is
unavailable or insufficient to hold harmless the Depositor, then (i) the Trustee
agrees that it shall contribute to the amount paid or payable to the Depositor
as a result of the losses, claims, damages or liabilities of the Depositor in
such proportion as is appropriate to reflect the relative fault of the Depositor
on the one hand and the Trustee on the other in connection with a breach of the
Trustee's obligations under this Section 8.17 or the Trustee's negligence, bad
faith or willful misconduct in connection therewith, (ii) the Master Servicer
agrees that it shall contribute to the amount paid or payable by the Depositor
as a result of the losses, claims, damages or liabilities of the Depositor in
such proportion as is appropriate to reflect the relative fault of the Depositor
on the one hand and the Master Servicer on the other in connection with a breach
of the Master Servicer's obligations under this Section 8.17 or the Master
Servicer's negligence, bad faith or willful misconduct in connection therewith
and (iii) the Special Servicer agrees that it shall contribute to the amount
paid or payable by the Depositor or the Master Servicer as a result of the
losses, claims, damages or liabilities of the Depositor or the Master Servicer
in such proportion as is appropriate to reflect the relative fault of the
Depositor or the Master Servicer on the one hand and the Special Servicer on the
other in connection with a breach of the Special Servicer's obligations under
this Section 8.17 or the Special Servicer's negligence, bad faith or willful
misconduct in connection therewith.

            (d) If the Trustee reasonably determines that it is required to file
any Servicer Report or any other servicing information with the Commission to
comply with the Sarbanes-Oxley Act, the Trustee may do so; provided that it has
either (i) provided the Depositor with written advice from a national reputable
counsel with an active commercial mortgage-backed securities practice reasonably
acceptable to the Depositor at least 10 Business Days prior to the first
occasion of such filing stating that the filing of any such Servicer Reports in
the filings described in Section 8.17(a) is required to comply with the Section
302 Requirements, or (ii) received the prior written consent not to be
unreasonably withheld of the Depositor to such filing.

            (e) Upon any filing with the Commission, the Trustee shall promptly
deliver to the Depositor, Master Servicer, each Rating Agency and Special
Servicer a copy of any such executed report, statement or information.

            (f) In performing its obligations under this Agreement, including
but not limited to this Section 8.17, none of the Trustee's or the Master
Servicer, on behalf of the Trust Fund, the Depositor or otherwise, shall be
responsible or liable for compliance with any reporting or filing requirement
under any state or federal securities laws, except to the extent such
requirement is specifically set forth in this Agreement.

            (g) Prior to January 30 of the first year in which the Trustee is
able to do so under applicable law, the Trustee shall file a Form 15 Suspension
Notification relating to the automatic suspension of reporting in respect of the
Trust under the Exchange Act (after which time no Form 8-K or Form 10-K shall be
filed unless otherwise required by the Exchange Act) and shall provide the
Depositor, the Special Servicer and Master Servicer with written notice of such
filing.

            (h) With respect to the Serviced Pari Passu Companion Loans then
included in a securitization, the Master Servicer and the Special Servicer shall
reasonably cooperate with the related trustee, depositor, master servicer and
special servicer with respect to such securitization(s) in connection with the
reporting requirements under the Exchange Act and shall provide such
certifications (including without limitation back-up certificates relating to
the requirements of the Sarbanes-Oxley Act) as reasonably requested; provided
that no such cooperation shall materially increase the obligations of the Master
Servicer and/or the Special Servicer under this Agreement.

            Section 8.18 Maintenance of Mortgage File.

            Except for the release of items in the Mortgage File contemplated by
this Agreement, including, without limitation, as necessary for the enforcement
of the holder's rights and remedies under the related Mortgage Loan, the Trustee
covenants and agrees that it shall maintain each Mortgage File in the State of
Illinois, and that it shall not move any Mortgage File outside the State of
Illinois, other than as specifically provided for in this Agreement, unless it
shall first obtain and provide, at the expense of the Trustee, an Opinion of
Counsel to the Depositor and the Rating Agencies to the effect that the
Trustee's first priority interest in the Mortgage Notes has been duly and fully
perfected under the applicable laws and regulations of such other jurisdiction.

            Section 8.19 The Fiscal Agent.

            (a) The Fiscal Agent shall at all times maintain a long-term
unsecured debt rating of no less than "AA-" from S&P (or "A+" from S&P, if the
Fiscal Agent's short-term unsecured debt rating is at least "A-1" by S&P) and
"AA-" from Fitch, or, in the case of either Rating Agency, such other rating as
shall not result in the withdrawal, downgrade, or qualification of the rating
assigned by the Rating Agency to any Class of Certificates then rated by the
Rating Agency, as confirmed in writing by such Rating Agency.

            (b) To the extent that the Trustee is required, pursuant to the
terms of this Agreement, to make any Advance, whether as successor master
servicer or otherwise, and has failed to do so in accordance with the terms
hereof, the Fiscal Agent shall make such Advance when and as required by the
terms of this Agreement on behalf the Trustee as if the Fiscal Agent were the
Trustee hereunder. To the extent that the Fiscal Agent makes an Advance pursuant
to this Section 8.19(b) or otherwise pursuant to this Agreement, the obligations
of the Trustee under this Agreement in respect of such Advance shall be
satisfied. Notwithstanding anything contained in this Agreement to the contrary,
the Fiscal Agent shall be entitled to all limitations on liability, rights of
reimbursement and indemnities that the Trustee is entitled to hereunder as if it
were the Trustee.

            (c) All fees and expenses of the Fiscal Agent (other than any
interest owed to the Fiscal Agent in respect of unreimbursed Advances) incurred
by the Fiscal Agent in connection with the transactions contemplated by this
Agreement shall be borne by the Trustee, and neither the Trustee nor the Fiscal
Agent shall be entitled to reimbursement therefor from any of the Trust Fund,
the Depositor, the Master Servicer or the Special Servicer.

            (d) The obligations of the Fiscal Agent set forth in this Section
8.19 or otherwise pursuant to this Agreement shall exist only for so long as the
Trustee that appointed it (or, in the case of the initial Fiscal Agent, so long
as the initial Trustee) shall act as Trustee hereunder. The Fiscal Agent may
resign or be removed by the Trustee only if and when the existence of such
Fiscal Agent is no longer necessary for such Trustee to satisfy the eligibility
requirements of Section 8.06; provided that the Fiscal Agent shall be deemed to
have resigned at such time as the Trustee that appointed it (or, in the case of
the initial Fiscal Agent, at such time as the initial Trustee) resigns or is
removed as Trustee hereunder (in which case the responsibility for appointing a
successor Fiscal Agent shall belong to the successor Trustee, and which
appointment the successor Trustee shall use its best efforts to make, insofar as
such appointment is necessary for such successor Trustee to satisfy the
eligibility requirements of Section 8.06). Any successor Fiscal Agent so
appointed shall be required to execute and deliver to the other parties hereto a
written agreement to assume and perform the duties of the Fiscal Agent set forth
in this Agreement; provided that no such successor shall become Fiscal Agent
hereunder unless either (i) it satisfies the rating requirements of Section
8.19(a) or (ii) the Trustee shall have received written confirmation from each
Rating Agency that the succession of such proposed successor Fiscal Agent would
not, in and of itself, result in the withdrawal, downgrade, or qualification of
the rating assigned by the Rating Agency to any Class of Certificates then rated
by the Rating Agency.

            (e) The Trustee shall promptly notify the other parties hereto and
the Certificateholders in writing of the appointment, resignation or removal of
any Fiscal Agent.

            Section 8.20 Representations and Warranties of the Fiscal Agent.

            The Fiscal Agent hereby represents and warrants to the Master
Servicer, the Special Servicer, the Depositor and the Trustee and for the
benefit of the Certificateholders, as of the Closing Date, that:

            (i) The Fiscal Agent is a foreign banking corporation duly
      organized, validly existing and in good standing under the laws governing
      its creation and possesses all licenses and authorizations necessary to
      the performance of its obligations under this Agreement.

            (ii) The execution and delivery of this Agreement by the Fiscal
      Agent, and the performance and compliance with the terms of this Agreement
      by the Fiscal Agent, will not violate the Fiscal Agent's organizational
      documents or constitute a default (or an event which, with notice or lapse
      of time, or both, would constitute a default) under, or result in a
      material breach of, any material agreement or other material instrument to
      which it is a party or by which it is bound.

            (iii) The Fiscal Agent has the full power and authority to carry on
      its business as now being conducted and to enter into and consummate all
      transactions contemplated by this Agreement, has duly authorized the
      execution, delivery and performance of this Agreement, and has duly
      executed and delivered this Agreement.

            (iv) This Agreement, assuming due authorization, execution and
      delivery by the other parties hereto, constitutes a valid, legal and
      binding obligation of the Fiscal Agent, enforceable against the Fiscal
      Agent in accordance with the terms hereof (including with respect to any
      advancing obligations hereunder), subject to (A) applicable bankruptcy,
      insolvency, reorganization, moratorium and other laws affecting the
      enforcement of creditors' rights generally and the rights of creditors of
      banks, and (B) general principles of equity, regardless of whether such
      enforcement is considered in a proceeding in equity or at law.

            (v) The Fiscal Agent is not in violation of, and its execution and
      delivery of this Agreement and its performance and compliance with the
      terms of this Agreement will not constitute a violation of, any law, any
      order or decree of any court or arbiter, or any order, regulation or
      demand of any federal, state or local governmental or regulatory
      authority, which violation, in the Fiscal Agent's good faith and
      reasonable judgment, is likely to affect materially and adversely the
      ability of the Fiscal Agent to perform its obligations under this
      Agreement.

            (vi) No litigation is pending or, to the best of the Fiscal Agent's
      knowledge, threatened against the Fiscal Agent that, if determined
      adversely to the Fiscal Agent, would prohibit the Fiscal Agent from
      entering into this Agreement or, in the Fiscal Agent's good faith and
      reasonable judgment, is likely to materially and adversely affect the
      ability of the Fiscal Agent to perform its obligations under this
      Agreement.

            (vii) Any consent, approval, authorization or order of any court or
      governmental agency or body required for the execution, delivery and
      performance by the Fiscal Agent of or compliance by the Fiscal Agent with
      this Agreement or the consummation of the transactions contemplated by
      this Agreement has been obtained and is effective.

            (viii) The Fiscal Agent is eligible to act hereunder in accordance
      with Section 8.19.

                                   ARTICLE IX

                                   TERMINATION

            Section 9.01 Termination Upon Repurchase or Liquidation of All
Mortgage Loans.

            Subject to Section 9.02, the Trust Fund and the respective
obligations and responsibilities under this Agreement of the Depositor, the
Master Servicer, the Special Servicer, the Fiscal Agent and the Trustee (other
than the obligations of the Trustee on behalf of the Trustee to provide for and
make payments to Certificateholders as hereafter set forth) shall terminate upon
payment (or provision for payment) (i) to the Certificateholders of all amounts
held by or on behalf of the Trustee and required hereunder to be so paid on the
Distribution Date following the earlier to occur of (A) the purchase by the
Master Servicer, the Special Servicer or the Majority Subordinate
Certificateholder of all Mortgage Loans, the REO Loans related to the 2005-C19
Serviced Mortgage Loan, the LB-UBS 2005-C3 Serviced Mortgage Loan and the MSCI
2005-HQ6 Serviced Mortgage Loan, if any, and each REO Property remaining in
REMIC I at a price equal to (1) the aggregate Purchase Price of all the Mortgage
Loans included in REMIC I, plus (2) the appraised value of the Trust Fund's
interest in each REO Property (other than the Trust Fund's beneficial interest
in any REO Property related to a Non-Serviced Mortgage Loan), if any, included
in REMIC I, such appraisal to be conducted by an Independent Appraiser selected
by the Master Servicer and approved by the Trustee, plus (3) with respect to any
REO Property related to the 2005-C19 Serviced Mortgage Loan, the LB-UBS 2005-C3
Serviced Mortgage Loan or the MSCI 2005-HQ6 Serviced Mortgage Loan, the pro rata
portion of the appraised value of such REO Property (based on an appraisal
conducted in accordance with the 2005-C19 Pooling and Servicing Agreement, the
LB-UBS 2005-C3 Pooling and Servicing Agreement and the MSCI 2005-HQ6 Pooling and
Servicing Agreement of the property owned by the 2005-C19 Trustee, the LB-UBS
2005-C3 Trustee and the MSCI 2005-HQ6 Trustee, as applicable, on behalf of the
owners thereof), based on the outstanding principal balances of the AmericasMart
Whole Loan, the 101 Avenue of the Americas Whole Loan or the U-Haul Portfolio
Whole Loan, as the case may be, minus (4) if the purchaser is the Master
Servicer, the aggregate amount of unreimbursed Advances made by the Master
Servicer, together with any interest accrued and payable to the Master Servicer
in respect of unreimbursed Advances in accordance with Sections 3.03(d) and
4.03(d) and any unpaid Master Servicing Fees remaining outstanding (which items
shall be deemed to have been paid or reimbursed to the Master Servicer in
connection with such purchase), and (B) the final payment or other liquidation
(or any advance with respect thereto) of the last Mortgage Loan or REO Property
remaining in REMIC I, and (ii) to the Trustee, the Fiscal Agent, the Master
Servicer, the Special Servicer and the officers, directors, employees and agents
of each of them of all amounts which may have become due and owing to any of
them hereunder; provided, however, that in no event shall the Trust Fund created
hereby continue beyond the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late ambassador of the
United States to the Court of St. James, living on the date hereof.

            Subject in each case to the terms of the related Intercreditor
Agreement, the obligations and responsibilities under this Agreement of the
Depositor, the Master Servicer, the Special Servicer, the Trustee, and the
Companion Paying Agent shall terminate with respect to any Companion Loan to the
extent (i) its related Co-Lender Loan has been paid in full or is no longer part
of the Trust Fund and (ii) no amounts payable by the related Companion Holder to
or for the benefit of the Trust Fund or any party hereto in accordance with the
related Intercreditor Agreement remain due and owing.

            The Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholder may at its option elect to purchase all of the
Mortgage Loans and each REO Property (or beneficial interest in an REO Property
related to a Non-Serviced Mortgage Loan) remaining in REMIC I as contemplated by
clause (i) of the preceding paragraph by giving written notice to the other
parties hereto no later than 60 days prior to the anticipated date of purchase;
provided, however, that (i) the aggregate Stated Principal Balance of the
Mortgage Pool at the time of such election is less than 1.0% of the aggregate
Cut-Off Date Balances of the Mortgage Loans, and (ii) the Master Servicer shall
not have the right to effect such a purchase if, within 30 days following the
Master Servicer's delivery of a notice of election pursuant to this paragraph,
the Special Servicer or the Majority Subordinate Certificateholder shall give
notice of its election to purchase all of the Mortgage Loans and each REO
Property (or beneficial interest in an REO Property related to a Non-Serviced
Mortgage Loan) remaining in REMIC I and shall thereafter effect such purchase in
accordance with the terms hereof. The Master Servicer or the Majority
Subordinate Certificateholder shall not have the right to effect such a purchase
if, within 30 days following the Special Servicer's delivery of a notice of
election pursuant to this paragraph, the Special Servicer shall give notice of
its election to purchase all of the Mortgage Loans and each REO Property (or
beneficial interest in an REO Property related to a Non-Serviced Mortgage Loan)
remaining in REMIC I and shall thereafter effect such purchase in accordance
with the terms hereof. If the Trust Fund is to be terminated in connection with
the Master Servicer's, the Special Servicer's or the Majority Subordinate
Certificateholder's purchase of all of the Mortgage Loans and each REO Property
(or beneficial interest in an REO Property related to a Non-Serviced Mortgage
Loan) remaining in REMIC I, the Master Servicer, the Special Servicer or the
Majority Subordinate Certificateholder, as applicable, shall deliver to the
Paying Agent for deposit in the Distribution Account not later than the P&I
Advance Date relating to the Distribution Date on which the final distribution
on the Certificates is to occur an amount in immediately available funds equal
to the above-described purchase price. In addition, the Master Servicer shall
transfer to the Distribution Account all amounts required to be transferred
thereto on such P&I Advance Date from the Certificate Account pursuant to the
first paragraph of Section 3.04(b), together with any other amounts on deposit
in the Certificate Account that would otherwise be held for future distribution.
Upon confirmation that such final deposit has been made, the Trustee shall
release or cause to be released to the Master Servicer, the Special Servicer,
the Majority Subordinate Certificateholder, as applicable, the Mortgage Files
for the remaining Mortgage Loans and shall execute all assignments, endorsements
and other instruments furnished to it by the Master Servicer, the Special
Servicer or the Majority Subordinate Certificateholder, as applicable, as shall
be necessary to effectuate transfer of the Mortgage Loans and REO Properties (or
beneficial interest in an REO Property related to a Non-Serviced Mortgage Loan)
to the Master Servicer, the Special Servicer or the Majority Subordinate
Certificateholder (or their respective designees), and, in the case of a Loan
Pair, to the related Companion Holder, as applicable. Any transfer of Mortgage
Loans to the Depositor pursuant to this paragraph shall be on a
servicing-released basis.

            Notice of any termination shall be given promptly by the Trustee by
letter to Certificateholders, the Class A-3SF Swap Counterparty and the Class
A-MFL Swap Counterparty mailed (a) if such notice is given in connection with
the Master Servicer's, the Special Servicer's or the Majority Subordinate
Certificateholder's purchase of the Mortgage Loans and each REO Property (or
beneficial interest in an REO Property related to a Non-Serviced Mortgage Loan)
remaining in REMIC I, not earlier than the 15th day and not later than the 25th
day of the month next preceding the month of the final distribution on the
Certificates or (b) otherwise during the month of such final distribution on or
before the Determination Date in such month, in each case specifying (i) the
Distribution Date upon which the Trust Fund will terminate and final payment of
the Certificates will be made, (ii) the amount of any such final payment and
(iii) that the Record Date otherwise applicable to such Distribution Date is not
applicable, payments being made only upon presentation and surrender of the
Certificates at the offices of the Certificate Registrar or such other location
therein designated. The Trustee shall give such notice to the Master Servicer,
the Special Servicer and the Depositor at the time such notice is given to
Certificateholders.

            Upon presentation and surrender of the Certificates by the
Certificateholders on the final Distribution Date, the Paying Agent shall
distribute to each Certificateholder so presenting and surrendering its
Certificates such Certificateholder's Percentage Interest of that portion of the
amounts then on deposit in the Distribution Account that are allocable to
payments on the Class of Certificates so presented and surrendered. Amounts on
deposit in the Distribution Account (or, in the case of the Class A-3SF
Certificates, amounts then on deposit in the Class A-3SF Floating Rate Account
after payment of the Class A-3SF Net Swap Payment to the Class A-3SF Swap
Counterparty, as specified in Section 4.01, or, in the case of the Class A-MFL
Certificates, amounts then on deposit in the Class A-MFL Floating Rate Account
after payment of any Class A-MFL Net Swap Payment to the Class A-MFL Swap
Counterparty, as specified in Section 4.01) as of the final Distribution Date,
exclusive of any portion thereof that would be payable to any Person in
accordance with clauses (ii) through (vii) of Section 3.05(b), including any
portion thereof that represents Prepayment Premiums and Yield Maintenance
Charges, shall be (i) deemed distributed in respect of the REMIC I Regular
Interests and distributed to the Class R-I Certificates in accordance with
Section 4.01(b), Section 4.01(h), Section 4.01(i) and Section 4.01(l) and (ii)
distributed to the REMIC II Certificates, the Class A-3SF Certificates and the
Class A-MFL Certificates in the order of priority set forth in Section 4.01(a),
Section 4.01(b), Section 4.01(c), Section 4.01(d), Section 4.01(j) and Section
4.01(k), in each case, to the extent of remaining available funds.

            On or after the Final Distribution Date, upon presentation and
surrender of the Class Certificates, the Paying Agent shall distribute to the
Class Z Certificateholders any amount then on deposit in the Additional Interest
Account that was paid on a Mortgage Loan.

            Any funds not distributed to any Holder or Holders of Certificates
of such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held
uninvested in trust and credited to the account or accounts of the appropriate
non-tendering Holder or Holders. If any Certificates as to which notice has been
given pursuant to this Section 9.01 shall not have been surrendered for
cancellation within six months after the time specified in such notice, the
Paying Agent shall mail a second notice to the remaining non-tendering
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been surrendered for
cancellation, the Paying Agent, directly or through an agent, shall take such
reasonable steps to contact the remaining non-tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate, and
shall deal with all such unclaimed amounts in accordance with applicable law.
The costs and expenses of holding such funds in trust and of contacting such
Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust hereunder.

            After the Registered Certificates and the Class A-1A Certificates
have been paid in full and the remaining outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder, such Certificateholder shall have the right to exchange all
of the Certificates held thereby for all of the Mortgage Loans and each REO
Property (or beneficial interest in an REO Property related to a Non-Serviced
Mortgage Loan) remaining in the Trust Fund by giving written notice to all
parties hereto no later than 30 days prior to the anticipated date of exchange.

            In the event that such Certificateholder shall elect to exchange all
of the Certificates held thereby for all of the Mortgage Loans and each REO
Property (or beneficial interest in an REO Property related to a Non-Serviced
Mortgage Loan) remaining in REMIC I in accordance with the preceding sentence,
such Certificateholder, not later than the date on which the final distribution
on the Certificates is to occur, shall deposit in the Certificate Account an
amount in immediately available funds equal to all amounts then due and owing to
the Master Servicer, the Special Servicer, the Trustee, the Paying Agent, the
Certificate Registrar and/or the REMIC Administrator hereunder. Upon
confirmation that such final deposits have been made and following the surrender
of all the Certificates held by such Certificateholder on the final Distribution
Date, the Custodian, on behalf of the Trustee, shall release or cause to be
released to such Certificateholder the Mortgage Files for the remaining Mortgage
Loans, and the Trustee shall execute all assignments, endorsements and other
instruments furnished to it by such Certificateholder as shall be necessary to
effectuate transfer of the Mortgage Loans and REO Properties (or beneficial
interest in an REO Property related to a Non-Serviced Mortgage Loan) remaining
in the Trust Fund. Thereafter, the Trust Fund and the respective obligations and
responsibilities under this Agreement of the Depositor, the Master Servicer, the
Special Servicer, the Trustee, the REMIC Administrator (other than annual tax
returns and maintenance of books and records and the preparation and filing of
final tax returns) and the Paying Agent shall terminate. Such transfers shall be
subject to any rights of any Sub-Servicers to primary service (or to perform
select servicing functions with respect to) the Mortgage Loans. For federal
income tax purposes, the Certificateholder shall be deemed to have purchased the
assets of REMIC I for an amount equal to the unpaid principal balance, plus
accrued unpaid interest, of the Mortgage Loan(s) (other than the defaulted
Mortgage Loan(s) or REO Property (or beneficial interest in an REO Property
related to a Non-Serviced Mortgage Loan)) in such REMICs and the fair market
value of any defaulted Mortgage Loans or REO Property (or beneficial interest in
an REO Property related to a Non-Serviced Mortgage Loan), without duplication of
amounts deposited pursuant to the fourth preceding sentence of this paragraph,
and such amounts shall be deemed to have been paid or distributed in accordance
with Section 4.01(a), Section 4.01(b), Section 4.01(h), Section 4.01(i) and
Section 4.01(j).

            In the case of any Loan Pair, references in this Section 9.01 and
Section 9.02 to "REO Property" shall include only the Trust's proportionate
interest in such REO Property and not the interest of the Companion Holder(s)
therein.

            Section 9.02 Additional Termination Requirements.

            (a) If the Master Servicer, the Special Servicer or the Majority
Subordinate Certificateholders purchase all of the Mortgage Loans and the Trust
Fund's interest in each REO Property (or beneficial interest in an REO Property
related to a Non-Serviced Mortgage Loan) remaining in REMIC I as provided in
Section 9.01, the Trust Fund (and, accordingly, either of REMIC I or REMIC II)
shall be terminated in accordance with the following additional requirements,
unless the Person effecting the purchase obtains at its own expense and delivers
to the Trustee and, in the case of the Depositor, to the Trustee and the Master
Servicer, an Opinion of Counsel, addressed to the Trustee and the Master
Servicer, to the effect that the failure of the Trust Fund to comply with the
requirements of this Section 9.02 will not result in the imposition of taxes on
"prohibited transactions" of either of REMIC I or REMIC II as defined in Section
860F of the Code or cause either of REMIC I or REMIC II to fail to qualify as a
REMIC at any time that any Certificates are outstanding:

            (i) the Trustee shall specify the first day in the 90-day
      liquidation period in a statement attached to the final Tax Return for
      REMIC I and REMIC II pursuant to Treasury Regulations Section 1.860F-1;

            (ii) during such 90-day liquidation period and at or prior to the
      time of making of the final payment on the Certificates, the Trustee shall
      sell all of the assets of REMIC I to the Master Servicer, the Special
      Servicer or the Majority Subordinate Certificateholders, as applicable,
      for cash; and

            (iii) at the time of the making of the final payment on the
      Certificates, the Trustee shall distribute or credit, or cause to be
      distributed or credited, to the Certificateholders in accordance with
      Section 9.01 all cash on hand (other than cash retained to meet claims),
      and REMIC I and REMIC II shall terminate at that time.

            (b) By their acceptance of Certificates, the Holders thereof hereby
authorize the Trustee to specify the 90-day liquidation period for REMIC I and
REMIC II, which authorization shall be binding upon all successor
Certificateholders.

            In the event the Trust Fund is to be terminated while the Class
A-3SF Swap Contract or the Class A-MFL Swap Contract is still in effect, the
Paying Agent shall promptly notify the applicable Swap Counterparty in writing
of the date on which the Trust Fund is to be terminated and the notional amount
of the applicable Swap Contract will be reduced to zero on such date. Based on
the date of termination, the Paying Agent shall calculate the Class A-3SF Net
Swap Payment or the Class A-MFL Net Swap Payment, as applicable, if any, as
specified in Section 3.28, and prior to any final distribution to the Holders of
the Class A-3SF Certificates or the Holders of the Class A-MFL Certificates, as
applicable, pursuant to Section 9.01, shall pay such Class A-3SF Net Swap
Payment or the Class A-MFL Net Swap Payment, as applicable, if any, to the
related Swap Counterparty. In the event that any fees (including termination
fees) will be payable to the related Swap Counterparty in connection with such
termination, such fees will be payable to the related Swap Counterparty solely
from amounts remaining in the applicable Class A-3SF Floating Rate Account or
the Class A-MFL Floating Rate Account after all distributions, to the Class
A-3SF Certificates and the Class A-MFL Certificates, respectively, are made
pursuant to Section 9.01.

                                   ARTICLE X

                            ADDITIONAL TAX PROVISIONS

            Section 10.01 REMIC Administration.

            (a) The REMIC Administrator shall elect to treat each of REMIC I and
REMIC II as a REMIC under the Code and, if necessary, under applicable state
law. Each such election will be made on Form 1066 or other appropriate federal
or state Tax Returns for the taxable year ending December 31, 2005, in the case
of each of REMIC I and REMIC II.

            (b) The REMIC I Regular Interests and the Regular Certificates, the
Class A-3SF Regular Interest and the Class A-MFL Regular Interest are hereby
designated as "regular interests" (within the meaning of Section 860G(a)(1) of
the Code) in REMIC I and REMIC II, respectively; provided that the REMIC regular
interest represented by the Class X-C Certificates shall have a pass-through
rate unreduced by any Class X-C Pass-Through Rate Reduction Percentage. In no
event shall the right of the Class A-MFL Swap Counterparty to receive the Class
A-MFL Swap Counterparty Special Payment be an interest in either REMIC, and the
Trustee shall treat the Class A-MFL Swap Counterparty Special Payment as having
been first distributed to the Holders of the Class X-C Certificates and then
distributed to the Class A-MFL Swap Counterparty outside of REMIC I and REMIC II
for all purposes of this Agreement. The Class R-I Certificates are hereby
designated as the single class of "residual interests" (within the meaning of
Section 860G(a)(2) of the Code) in REMIC I, and the Class R-II Certificates are
hereby designated as the single class of "residual interests" (within the
meaning of Section 860G(a)(2) of the Code) in REMIC II. None of the Master
Servicer, the Special Servicer or the Trustee shall (to the extent within its
control) permit the creation of any other "interests" in either of REMIC I or
REMIC II (within the meaning of Treasury regulation Section 1.860D-1(b)(1)).

            (c) The Closing Date is hereby designated as the "startup day" of
each of REMIC I and REMIC II within the meaning of Section 860G(a)(9) of the
Code. The "latest possible maturity date" of the REMIC I Regular Interests and
the Regular Certificates for purposes of the REMIC Provisions shall be the Rated
Final Distribution Date.

            (d) The related Plurality Residual Certificateholder as to the
applicable taxable year is hereby designated as the Tax Matters Person of each
of REMIC I and REMIC II, and shall act on behalf of the related REMIC in
relation to any tax matter or controversy and shall represent the related REMIC
in any administrative or judicial proceeding relating to an examination or audit
by any governmental taxing authority; provided that the REMIC Administrator is
hereby irrevocably appointed to act and shall act as agent and attorney-in-fact
for the Tax Matters Person for REMIC I and REMIC II in the performance of its
duties as such.

            (e) Except as otherwise provided in Section 3.17(a) and subsections
(h) and (i) below, the REMIC Administrator shall pay out of its own funds any
and all routine tax administration expenses of the Trust Fund incurred with
respect to either of REMIC I and REMIC II (but not including any professional
fees or expenses related to audits or any administrative or judicial proceedings
with respect to the Trust Fund that involve the Internal Revenue Service or
state tax authorities, which extraordinary expenses shall be payable or
reimbursable to the Trustee from the Trust Fund unless otherwise provided in
Section 10.01(g) or 10.01(h)).

            (f) Within 30 days after the Closing Date, the REMIC Administrator
shall obtain taxpayer identification numbers for REMIC I and REMIC II by
preparing and filing Internal Revenue Service Forms SS-4 and shall prepare and
file (if not previously prepared and filed) with the Internal Revenue Service
Form 8811, "Information Return for Real Estate Mortgage Investment Conduits
(REMIC) and Issuers of Collateralized Debt Obligations" for the Trust Fund. In
addition, the REMIC Administrator shall prepare, cause the Trustee to sign and
file all of the other Tax Returns in respect of each of REMIC I and REMIC II.
The expenses of preparing and filing such returns shall be borne by the REMIC
Administrator without any right of reimbursement therefor. The other parties
hereto shall provide on a timely basis to the REMIC Administrator or its
designee such information with respect to REMIC I and REMIC II as is in its
possession and reasonably requested by the REMIC Administrator to enable it to
perform its obligations under this Article. Without limiting the generality of
the foregoing, the Depositor, within ten days following the REMIC
Administrator's request therefor, shall provide in writing to the REMIC
Administrator such information as is reasonably requested by the REMIC
Administrator for tax purposes, as to the valuations and issue prices of the
Certificates, and the REMIC Administrator's duty to perform its reporting and
other tax compliance obligations under this Article X shall be subject to the
condition that it receives from the Depositor such information possessed by the
Depositor that is necessary to permit the REMIC Administrator to perform such
obligations.

            (g) The REMIC Administrator shall perform on behalf of each of REMIC
I and REMIC II all reporting and other tax compliance duties that are the
responsibility of each such REMIC under the Code, the REMIC Provisions or other
compliance guidance issued by the Internal Revenue Service or, with respect to
State and Local Taxes, any state or local taxing authority. Included among such
duties, the REMIC Administrator shall provide to: (i) any Transferor of a
Residual Certificate or agent of a Non-Permitted Transferee, such information as
is necessary for the application of any tax relating to the transfer of a
Residual Certificate to any Person who is not a Permitted Transferee; (ii) the
Certificateholders, such information or reports as are required by the Code or
the REMIC Provisions, including, without limitation, reports relating to
interest, original issue discount and market discount or premium (using the
Prepayment Assumption as required hereunder); and (iii) the Internal Revenue
Service, the name, title, address and telephone number of the Person who will
serve as the representative of each of REMIC I and REMIC II.

            (h) The REMIC Administrator shall perform its duties hereunder so as
to maintain the status of each of REMIC I and REMIC II as a REMIC under the
REMIC Provisions (and the Trustee, the Master Servicer and the Special Servicer
shall assist the REMIC Administrator to the extent reasonably requested by the
REMIC Administrator and to the extent of information within the Trustee's, the
Master Servicer's or the Special Servicer's possession or control). None of the
REMIC Administrator, Master Servicer, the Special Servicer, or the Trustee shall
knowingly take (or cause either of REMIC I or REMIC II to take) any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of either of REMIC I or REMIC II as a REMIC, or (ii) except as provided
in Section 3.17(a), result in the imposition of a tax upon either of REMIC I or
REMIC II (including, but not limited to, the tax on prohibited transactions as
defined in Section 860F(a)(2) of the Code or the tax on contributions to a REMIC
set forth in Section 860G(d) of the Code (any such endangerment or imposition
or, except as provided in Section 3.17(a), imposition of a tax, an "Adverse
REMIC Event")), unless the REMIC Administrator has obtained or received an
Opinion of Counsel (at the expense of the party requesting such action or at the
expense of the Trust Fund if the REMIC Administrator seeks to take such action
or to refrain from acting for the benefit of the Certificateholders) to the
effect that the contemplated action will not result in an Adverse REMIC Event.
The REMIC Administrator shall not take any action or fail to take any action
(whether or not authorized hereunder) as to which the Master Servicer or the
Special Servicer has advised it in writing that either the Master Servicer or
the Special Servicer has received or obtained an Opinion of Counsel to the
effect that an Adverse REMIC Event could occur with respect to such action. In
addition, prior to taking any action with respect to either of REMIC I or REMIC
II, or causing either of REMIC I or REMIC II to take any action that is not
expressly permitted under the terms of this Agreement, the Master Servicer and
the Special Servicer shall consult with the REMIC Administrator or its designee,
in writing, with respect to whether such action could cause an Adverse REMIC
Event to occur. Neither the Master Servicer nor the Special Servicer shall take
any such action or cause either of REMIC I or REMIC II to take any such action
as to which the REMIC Administrator has advised it in writing that an Adverse
REMIC Event could occur, and neither the Master Servicer nor the Special
Servicer shall have any liability hereunder for any action taken by it in
accordance with the written instructions of the REMIC Administrator. The REMIC
Administrator may consult with counsel to make such written advice, and the cost
of same shall be borne by the party seeking to take the action not expressly
permitted by this Agreement, but in no event at the cost or expense of the Trust
Fund, the Trustee or the REMIC Administrator. At all times as may be required by
the Code, the REMIC Administrator (to the extent it is within its control) shall
take all necessary actions within the scope of its responsibilities as more
specifically set forth in this Agreement such that it does not cause
substantially all of the assets of each of REMIC I and REMIC II to fail to
consist of "qualified mortgages" as defined in Section 860G(a)(3) of the Code
and "permitted investments" as defined in Section 860G(a)(5) of the Code.

            (i) If any tax is imposed on either of REMIC I or REMIC II,
including, without limitation, "prohibited transactions" taxes as defined in
Section 860F(a)(2) of the Code, any tax on "net income from foreclosure
property" as defined in Section 860G(c) of the Code, any taxes on contributions
to either of REMIC I or REMIC II after the Startup Day pursuant to Section
860G(d) of the Code, and any other tax imposed by the Code or any applicable
provisions of State or Local Tax laws (other than any tax permitted to be
incurred by the Special Servicer pursuant to Section 3.17(a)), such tax,
together with all incidental costs and expenses (including, without limitation,
penalties and reasonable attorneys' fees), shall be charged to and paid by: (i)
the REMIC Administrator, if such tax arises out of or results from a breach by
the REMIC Administrator of any of its obligations under this Article X; provided
that no liability shall be imposed upon the REMIC Administrator under this
clause if another party has responsibility for payment of such tax under clauses
(iii) or (v) of this Section; (ii) the Special Servicer, if such tax arises out
of or results from a breach by the Special Servicer of any of its obligations
under Article III or this Article X; (iii) the Master Servicer, if such tax
arises out of or results from a breach by the Master Servicer of any of its
obligations under Article III or this Article X; (iv) the Trustee if such tax
arises out of or results from a breach by the Trustee of any of its respective
obligations under Article IV, Article VIII or this Article X; (v) the Mortgage
Loan Seller, if such tax was imposed due to the fact that any of the Mortgage
Loans did not, at the time of their transfer to REMIC I, as applicable,
constitute a "qualified mortgage" as defined in Section 860G(a)(3) of the Code;
or (vi) the Trust Fund, excluding the portion thereof constituting the Grantor
Trusts, in all other instances. Any tax permitted to be incurred by the Special
Servicer pursuant to Section 3.17(a) shall be charged to and paid by the Trust
Fund. Any such amounts payable by the Trust Fund shall be paid by the Paying
Agent upon the written direction of the REMIC Administrator out of amounts on
deposit in the Distribution Account in reduction of the Available Distribution
Amount pursuant to Section 3.05(b).

            (j) The REMIC Administrator shall, for federal income tax purposes,
maintain books and records with respect to REMIC I and REMIC II on a calendar
year and on an accrual basis.

            (k) Following the Startup Day, none of the Trustee, the Master
Servicer or the Special Servicer shall accept any contributions of assets to
either of REMIC I or REMIC II unless it shall have received an Opinion of
Counsel (at the expense of the party seeking to cause such contribution and in
no event at the expense of the Trust Fund or the Trustee) to the effect that the
inclusion of such assets in such REMIC will not cause: (i) such REMIC to fail to
qualify as a REMIC at any time that any Certificates are outstanding; or (ii)
the imposition of any tax on such REMIC under the REMIC Provisions or other
applicable provisions of federal, state and local law or ordinances.

            (l) None of the Trustee, the Master Servicer or the Special Servicer
shall consent to or, to the extent it is within the control of such Person,
permit: (i) the sale or disposition of any of the Mortgage Loans (except in
connection with (A) the default or foreclosure of a Mortgage Loan, including,
but not limited to, the sale or other disposition of a Mortgaged Property
acquired by deed in lieu of foreclosure, (B) the bankruptcy of either of REMIC I
or REMIC II, (C) the termination of either of REMIC I and REMIC II pursuant to
Article IX of this Agreement, or (D) a purchase of Mortgage Loans pursuant to or
as contemplated by Article II or III of this Agreement); (ii) the sale or
disposition of any investments in the Servicing Accounts, the Interest Reserve
Accounts, the Certificate Account, the Distribution Account, the Companion
Distribution Account, the Class A-3SF Floating Rate Account, the Class A-MFL
Floating Rate Account, the Gain-on-Sale Reserve Account or the REO Account for
gain; or (iii) the acquisition of any assets on behalf of either of REMIC I or
REMIC II (other than (1) a Mortgaged Property acquired through foreclosure, deed
in lieu of foreclosure or otherwise in respect of a Defaulted Mortgage Loan, (2)
a Qualified Substitute Mortgage Loan pursuant to Article II hereof and (3)
Permitted Investments acquired in connection with the investment of funds in the
Servicing Accounts, the Interest Reserve Accounts, the Certificate Account, the
Distribution Account, the Class A-3SF Floating Rate Account, the Class A-MFL
Floating Rate Account, the Companion Distribution Account, the Gain-on-Sale
Reserve Account or the REO Account); in any event unless it has received an
Opinion of Counsel (at the expense of the party seeking to cause such sale,
disposition, or acquisition but in no event at the expense of the Trust Fund or
the Trustee) to the effect that such sale, disposition, or acquisition will not
cause: (x) either of REMIC I or REMIC II to fail to qualify as a REMIC at any
time that any Certificates are outstanding; or (y) the imposition of any tax on
either of REMIC I or REMIC II under the REMIC Provisions or other applicable
provisions of federal, state and local law or ordinances.

            (m) Except as permitted by Section 3.17(a), none of the Trustee, the
Master Servicer and the Special Servicer shall enter into any arrangement by
which either of REMIC I or REMIC II will receive a fee or other compensation for
services nor permit either of REMIC I or REMIC II to receive any income from
assets other than "qualified mortgages" as defined in Section 860G(a)(3) of the
Code or "permitted investments" as defined in Section 860G(a)(5) of the Code.

            (n) The Trustee shall treat the Class X-C Certificates as
representing regular interests in REMIC II, in the form of the Corresponding
Components, with a pass-through rate unreduced by any Class X-C Pass-Through
Rate Reduction Percentage, coupled with an obligation under an interest rate cap
contract entered into by the Holders of the Class X-C Certificates and the Class
A-MFL Swap Counterparty, on behalf of the Class A-MFL Certificates, under which
the Holders of the Class X-C Certificates are obligated to pay the Class A-MFL
Special Payment, on each Distribution Date during any Class X-C Pass-Through
Rate Reduction Period. The Holders of the Class X-C Certificates may be deemed
to receive a payment upon purchase of the Class X-C Certificates, such that the
Class X-C Certificates would then be deemed to be purchased at a greater
discount, and the Holders of the Class X-C Certificates would then be deemed to
have received a payment under an interest rate cap contract. However, the
Trustee is instructed to treat the amount of any such payment as being zero,
unless and until required to do otherwise by the applicable tax authorities.

            Section 10.02 Administration of the Grantor Trusts.

            (a) The REMIC Administrator shall treat the Additional Interest
Grantor Trust, for tax return preparation purposes, as a grantor trust under the
Code and shall treat the Additional Interest, the Additional Interest Account
and amounts held from time to time in the Additional Interest Account that
represent Additional Interest as separate assets of the Additional Interest
Grantor Trust, and not any of REMIC I, REMIC II, the Class A-3SF Grantor Trust
or the Class A-MFL Grantor Trusts permitted by Treasury Regulations Section
1.860G-2(i)(1). The Class Z Certificates are hereby designated as representing
an undivided, beneficial interest in Additional Interest payable on the Mortgage
Loans and proceeds thereof in the Additional Interest Account.

            (b) The REMIC Administrator shall treat the Class A-3SF Grantor
Trust, for tax return preparation purposes, as a grantor trust under the Code
and shall treat the Class A-3SF Regular Interest, the Class A-3SF Swap Contract
and the Class A-3SF Floating Rate Account and amounts held from time to time in
the Class A-3SF Floating Rate Account as separate assets of the A-3SF Grantor
Trust, and not any of REMIC I, REMIC II or the Additional Interest Grantor
Trust, as permitted by Treasury Regulations Section 1.860G-2(i)(1). The Class
A-3SF Certificates are hereby designated as representing an undivided,
beneficial interest in the Class A-3SF Grantor Trust Assets.

            (c) The REMIC Administrator shall treat the Class A-MFL Grantor
Trust, for tax return preparation purposes, as a grantor trust under the Code
and shall treat the Class A-MFL Regular Interest, the Class A-MFL Swap Contract
and the Class A-MFL Floating Rate Account and amounts held from time to time in
the Class A-MFL Floating Rate Account as separate assets of the A-MFL Grantor
Trust, and not any of REMIC I, REMIC II or the Additional Interest Grantor
Trust, as permitted by Treasury Regulations Section 1.860G-2(i)(1). The Class
A-MFL Certificates are hereby designated as representing an undivided,
beneficial interest in the Class A-MFL Grantor Trust Assets.

            (d) The REMIC Administrator shall pay out of its own funds any and
all routine tax administration expenses of the Trust Fund incurred with respect
to the Grantor Trusts (but not including any professional fees or expenses
related to audits or any administrative or judicial proceedings with respect to
the Trust Fund that involve the Internal Revenue Service or state tax
authorities which extraordinary expenses shall be payable or reimbursable to the
REMIC Administrator from the Trust Fund unless otherwise provided in Section
10.02(e) or 10.02(f)).

            (e) The REMIC Administrator shall prepare, cause the Trustee to sign
and file when due all of the Tax Returns in respect of the Grantor Trusts. The
expenses of preparing and filing such returns shall be borne by the REMIC
Administrator without any right of reimbursement therefor. The other parties
hereto shall provide on a timely basis to the REMIC Administrator or its
designee such information with respect to the Grantor Trusts as is in its
possession and reasonably requested by the REMIC Administrator to enable it to
perform its obligations under this Section 10.02. Without limiting the
generality of the foregoing, the Depositor, within ten days following the REMIC
Administrator's request therefor, shall provide in writing to the REMIC
Administrator such information as is reasonably requested by the REMIC
Administrator for tax purposes, and the REMIC Administrator's duty to perform
its reporting and other tax compliance obligations under this Section 10.02
shall be subject to the condition that it receives from the Depositor such
information possessed by the Depositor that is necessary to permit the REMIC
Administrator to perform such obligations.

            (f) The REMIC Administrator shall furnish or cause to be furnished
to the Class Z Certificateholders, the Class A-3SF Certificateholders, the Class
A-MFL Certificateholders on the cash or accrual method of accounting, as
applicable, such information as to their respective portions of the income and
expenses of the Grantor Trusts, at the time and in the manner required under the
Code, and shall perform on behalf of the Grantor Trusts all reporting and other
tax compliance duties that are required in respect thereof under the Code, the
Grantor Trust Provisions or other compliance guidance issued by the Internal
Revenue Service or any state or local taxing authority.

            (g) The REMIC Administrator shall perform its duties hereunder so as
to maintain the status of the Grantor Trusts as grantor trusts under the Grantor
Trust Provisions (and the Trustee, the Master Servicer and the Special Servicer
shall assist the REMIC Administrator to the extent reasonably requested by the
REMIC Administrator and to the extent of information within the Trustee's, the
Master Servicer's or the Special Servicer's possession or control). None of the
REMIC Administrator, Master Servicer, the Special Servicer or the Trustee shall
knowingly take (or cause the Grantor Trusts to take) any action or fail to take
(or fail to cause to be taken) any action that, under the Grantor Trust
Provisions, if taken or not taken, as the case may be, could endanger the status
of the Grantor Trusts as grantor trusts under the Grantor Trust Provisions (any
such endangerment of grantor trust status, an "Adverse Grantor Trust Event"),
unless the REMIC Administrator has obtained or received an Opinion of Counsel
(at the expense of the party requesting such action or at the expense of the
Trust Fund if the REMIC Administrator seeks to take such action or to refrain
from taking any action for the benefit of the Certificateholders) to the effect
that the contemplated action will not result in an Adverse Grantor Trust Event.
None of the other parties hereto shall take any action or fail to take any
action (whether or not authorized hereunder) as to which the REMIC Administrator
has advised it in writing that the REMIC Administrator has received or obtained
an Opinion of Counsel to the effect that an Adverse Grantor Trust Event could
result from such action or failure to act. In addition, prior to taking any
action with respect to the Grantor Trusts, or causing the Trust Fund to take any
action, that is not expressly permitted under the terms of this Agreement, the
Master Servicer and the Special Servicer shall consult with the REMIC
Administrator or its designee, in writing, with respect to whether such action
could cause an Adverse Grantor Trust Event to occur. Neither the Master Servicer
nor the Special Servicer shall have any liability hereunder for any action taken
by it in accordance with the written instructions of the REMIC Administrator.
The REMIC Administrator may consult with counsel to make such written advice,
and the cost of same shall be borne by the party seeking to take the action not
expressly permitted by this Agreement, but in no event at the cost or expense of
the Trust Fund, the REMIC Administrator or the Trustee. Under no circumstances
may the REMIC Administrator vary the assets of the Grantor Trusts so as to take
advantage of variations in the market so as to improve the rate of return of
Holders of the Class Z Certificates, the Class A-3SF Certificates or the Class
A-MFL Certificates.

            (h) If any tax is imposed on a Grantor Trust, such tax, together
with all incidental costs and expenses (including, without limitation, penalties
and reasonable attorneys' fees), shall be charged to and paid by: (i) the REMIC
Administrator, if such tax arises out of or results from a breach by the REMIC
Administrator of any of its obligations under this Section 10.02; (ii) the
Special Servicer, if such tax arises out of or results from a breach by the
Special Servicer of any of its obligations under Article III or this Section
10.02; (iii) the Master Servicer, if such tax arises out of or results from a
breach by the Master Servicer of any of its obligations under Article III or
this Section 10.02; (iv) the Trustee, if such tax arises out of or results from
a breach by the Trustee, of any of its obligations under Article IV, Article
VIII or this Section 10.02; or (v) the portion of the Trust Fund constituting
the Grantor Trusts in all other instances.

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

            Section 11.01 Amendment.

            (a) This Agreement may be amended from time to time by the mutual
agreement of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent, without the consent of any of the
Certificateholders or Companion Holders, (i) to cure any ambiguity, (ii) to
correct, modify or supplement any provision herein which may be inconsistent
with any other provision herein, (iii) to add any other provisions with respect
to matters or questions arising hereunder which shall not be inconsistent with
the provisions hereof, (iv) to relax or eliminate any requirement hereunder
imposed by the REMIC Provisions if the REMIC Provisions are amended or clarified
such that any such requirement may be relaxed or eliminated, or (v) if such
amendment, as evidenced by an Opinion of Counsel (at the expense of the Trust
Fund, in the case of any amendment requested by the Master Servicer or Special
Servicer that protects or is in furtherance of the interests of the
Certificateholders, and otherwise at the expense of the party seeking such
amendment) delivered to the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent, is advisable or reasonably necessary to comply with any
requirements imposed by the Code or any successor or amendatory statute or any
temporary or final regulation, revenue ruling, revenue procedure or other
written official announcement or interpretation relating to federal income tax
laws or any such proposed action which, if made effective, would apply
retroactively to REMIC I or REMIC II created hereunder at least from the
effective date of such amendment, or would be necessary to avoid the occurrence
of a prohibited transaction or to reduce the incidence of any tax that would
arise from any actions taken with respect to the operation of any such REMIC or
to comply with any requirements imposed by the Commission with respect to any
adopted temporary or final regulation or other written official announcement or
interpretation relating to the securities laws which, would apply retroactively
to the Depositor, any Underwriter or the Trust Fund; provided that such action
(except any amendment described in clause (v) above) shall not, as evidenced by
an Opinion of Counsel (at the expense of the Trust Fund, in the case of any
amendment requested by the Master Servicer or Special Servicer that protects or
is in furtherance of the interests of the Certificateholders, and otherwise at
the expense of the party seeking such amendment) obtained by or delivered to the
Master Servicer, the Special Servicer, the Trustee and the Fiscal Agent,
adversely affect in any material respect the interests of any Certificateholder
or Companion Holder with respect to the Pari Passu Mortgage Loans; provided,
further, that the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent shall have first obtained from each Rating Agency written
confirmation that such amendment will not result in the qualification, downgrade
or withdrawal of the rating on any Class of Certificates.

            (b) This Agreement may also be amended from time to time by the
agreement of the Depositor, the Master Servicer, the Special Servicer, the
Trustee and the Fiscal Agent with the consent of the Holders of Certificates
entitled to at least 51% of the Voting Rights allocated to the affected Classes
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Agreement or of modifying in any
manner the rights of the Holders of Certificates; provided, however, that no
such amendment shall (i) reduce in any manner the amount of, or delay the timing
of, payments received or advanced on Mortgage Loans that are required to be
distributed on any Certificate without the consent of the Holder of such
Certificate, or which are required to be distributed to a Companion Holder,
without the consent of such Companion Holder, (ii) as evidenced by an Opinion of
Counsel obtained by or delivered to the Master Servicer, the Special Servicer
and the Trustee, adversely affect in any material respect the interests of the
Holders of any Class of Certificates or the interests of a Companion Holder in a
manner other than as described in (i) without the consent of the Holders of all
Certificates of such Class or the consent of such Companion Holders, as the case
may be, (iii) modify the provisions of this Section 11.01 without the consent of
the Holders of all Certificates then outstanding and the consent of all
Companion Holders, (iv) modify the provisions of Section 3.20 or the definition
of Servicing Standard without the consent of the Holders of Certificates
entitled to all of the Voting Rights and the consent of all Companion Holders or
(v) modify the specified percentage of Voting Rights which are required to be
held by Certificateholders to consent or not to object to any particular action
pursuant to any provision of this Agreement without the consent of the Holders
of all Certificates then outstanding. Notwithstanding any other provision of
this Agreement, for purposes of the giving or withholding of consents pursuant
to this Section 11.01, Certificates registered in the name of the Depositor or
any Affiliate of the Depositor shall be entitled to the same Voting Rights with
respect to matters described above as they would if any other Person held such
Certificates, so long as neither the Depositor nor any of its Affiliates is
performing servicing duties with respect to any of the Mortgage Loans.

            (c) Notwithstanding any contrary provision of this Agreement, the
Trustee shall not consent to any amendment to this Agreement unless it shall
first have obtained or been furnished with an Opinion of Counsel (at the expense
of the Trust Fund, in the case of any amendment requested by the Master Servicer
or Special Servicer that protects or is in furtherance of the interests of the
Certificateholders, and, otherwise, at the expense of the party seeking such
amendment) to the effect that (i) such amendment or the exercise of any power
granted to the Trustee, the Fiscal Agent, the Master Servicer or the Special
Servicer in accordance with such amendment will not result in the imposition of
a tax on either of REMIC I or REMIC II pursuant to the REMIC Provisions or on
the Grantor Trusts or cause either of REMIC I or REMIC II to fail to qualify as
a REMIC or the Grantor Trusts to fail to qualify as a grantor trust at any time
that any Certificates are outstanding and (ii) such amendment complies with the
provisions of this Section 11.01.

            (d) Promptly after the execution of any such amendment, the Trustee
shall send a copy thereof to each Certificateholder and Companion Holder.

            (e) It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

            (f) Each of the Master Servicer, the Special Servicer, the Trustee
and the Fiscal Agent may but shall not be obligated to enter into any amendment
pursuant to this Section that affects its rights, duties and immunities under
this Agreement or otherwise.

            (g) The cost of any Opinion of Counsel to be delivered pursuant to
Section 11.01(a), (b) or (c) shall be borne by the Person seeking the related
amendment, except that if the Master Servicer, the Special Servicer, the Trustee
or the Fiscal Agent requests any amendment of this Agreement that protects or is
in furtherance of the rights and interests of Certificateholders, the cost of
any Opinion of Counsel required in connection therewith pursuant to Section
11.01(a), (b) or (c) shall be payable out of the Certificate Account or the
Distribution Account pursuant to Sections 3.05 and 4.01. Notwithstanding any
contrary provisions of this Agreement, this Agreement may not be amended in a
manner that would adversely affect the distributions to the related Swap
Counterparty, the Class A-3SF Certificates or the Class A-MFL Certificates or
the rights of the related Swap Counterparty under the related Swap Contract or
the rights of the holders of the Class A-3SF Certificates or the Class A-MFL
Certificates without the consent of the related Swap Counterparty and 66 2/3% of
the Holders of the Class A-3SF Certificates and the Class A-MFL Certificates,
respectively.

            (h) Notwithstanding anything in this Agreement to the contrary, the
Trustee shall deliver a copy of any proposed amendment to this Agreement to the
related Swap Counterparty and any amendment to this Agreement that could
reasonably materially and adversely affect the related Swap Counterparty
(whether or not the related Swap Contract is specifically referred to or
identified in the proposed amendment) shall be subject to the related Swap
Counterparty's prior written consent.

            Section 11.02 Recordation of Agreement; Counterparts.

            (a) To the extent permitted by applicable law, this Agreement is
subject to recordation in all appropriate public offices for real property
records in all the counties or other comparable jurisdictions in which any or
all of the properties subject to the Mortgages are situated, and in any other
appropriate public recording office or elsewhere, such recordation to be
effected by the Master Servicer at the expense of the Trust Fund, but only upon
direction accompanied by an Opinion of Counsel (the cost of which may be paid
out of the Certificate Account pursuant to Section 3.05(a)) to the effect that
such recordation materially and beneficially affects the interests of the
Certificateholders; provided, however, that the Trustee shall have no obligation
or responsibility to determine whether any such recordation of this Agreement is
required.

            (b) For the purpose of facilitating the recordation of this
Agreement as herein provided and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and such counterparts shall
constitute but one and the same instrument.

            Section 11.03 Limitation on Rights of Certificateholders.

            (a) The death or incapacity of any Certificateholder shall not
operate to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

            (b) No Certificateholder shall have any right to vote (except as
expressly provided for herein) or in any manner otherwise control the operation
and management of the Trust Fund, or the obligations of the parties hereto, nor
shall anything herein set forth, or contained in the terms of the Certificates,
be construed so as to constitute the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholder be under
any liability to any third party by reason of any action taken by the parties to
this Agreement pursuant to any provision hereof.

            (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement or any Mortgage
Loan, unless, with respect to any suit, action or proceeding upon or under or
with respect to this Agreement, such Holder previously shall have given to the
Trustee a written notice of default hereunder, and of the continuance thereof,
as hereinbefore provided, and unless also (except in the case of a default by
the Trustee) the Holders of Certificates entitled to at least 25% of the Voting
Rights shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, and the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding. It is understood and intended, and expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner
whatsoever by virtue of any provision of this Agreement to affect, disturb or
prejudice the rights of the Holders of any other of such Certificates, or to
obtain or seek to obtain priority over or preference to any other such Holder,
which priority or preference is not otherwise provided for herein, or to enforce
any right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Certificateholders. For the protection
and enforcement of the provisions of this Section, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

            Section 11.04 Governing Law.

            This Agreement and the Certificates shall be construed in accordance

            Section 11.06 Severability of Provisions.

            If any one or more of the covenants, agreements, provisions or terms
of this Agreement shall be for any reason whatsoever held invalid, then such
covenants, agreements, provisions or terms shall be deemed severable from the
remaining covenants, agreements, provisions or terms of this Agreement and shall
in no way affect the validity or enforceability of the other provisions of this
Agreement or of the Certificates or the rights of the Holders thereof.

            Section 11.07 Grant of a Security Interest.

            The Depositor intends that the conveyance of the Depositor's right,

constitute a sale and not a pledge of security for a loan. If such conveyance is
deemed to be a pledge of security for a loan, however, the Depositor intends
that the rights and obligations of the parties to such loan shall be established
pursuant to the terms of this Agreement. The Depositor also intends and agrees
that, in such event, the Depositor shall be deemed to have granted to the
Trustee (in such capacity) a first priority security interest in the Depositor's
entire right, title and interest in and to the assets constituting the Trust
Fund.

            Section 11.08 Streit Act.

            Any provisions required to be contained in this Agreement by Section
126 of Article 4-A of the New York Real Property Law are hereby incorporated
herein, and such provisions shall be in addition to those conferred or imposed
by this Agreement; provided, however, that to the extent that such Section 126
shall not have any effect, and if said Section 126 should at any time be
repealed or cease to apply to this Agreement or be construed by judicial
decision to be inapplicable, said Section 126 shall cease to have any further
effect upon the provisions of this Agreement. In case of a conflict between the
provisions of this Agreement and any mandatory provisions of Article 4-A of the
New York Real Property Law, such mandatory provisions of said Article 4-A shall
prevail; provided that if said Article 4-A shall not apply to this Agreement,
should at any time be repealed or cease to apply to this Agreement or be
construed by judicial decision to be inapplicable, such mandatory provisions of
such Article 4-A shall cease to have any further effect upon the provisions of
this Agreement.

            Section 11.09 Successors and Assigns; Beneficiaries.

            The provisions of this Agreement shall be binding upon and inure to
the benefit of the respective successors and assigns of the parties hereto, and
all such provisions shall inure to the benefit of the Certificateholders. This
Agreement may not be amended in any manner that would adversely affect the
rights of any third party beneficiary hereof without its consent. The 2005-C19
Master Servicer, the LB-UBS 2005-C3 Master Servicer and the MSCI 2005-HQ6 Master
Servicer shall be third party beneficiaries to this Agreement solely with
respect to the reimbursement of nonrecoverable advances made by such party under

successor entity under the Agreement), CWCapital Asset Management LLC (herein
called the "Special Servicer," which term includes any successor entity under

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class A-1 Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class A-1 Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a

no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent

Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes

of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class A-1 Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class A-1 Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class A-1 Certificates are exchangeable for new Class A-1 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-1 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-1 Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class A-1
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and

Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-1

1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the

any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class A-2 Certificates

the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such

therein set forth, the transfer of this Certificate is registrable in the

authorized in writing, and thereupon one or more new Class A-2 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

or exchange of Class A-2 Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class A-2
Certificates.

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,

Certificates will be made by LaSalle Bank National Association, as paying agent

account of the Person entitled thereto at a bank or other entity having

to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on

of any Realized Loss or Additional Trust Fund Expense previously allocated to
this Certificate) will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution. Also notwithstanding the foregoing, any distribution that may be
made with respect to this Certificate in reimbursement of any Realized Loss or
Additional Trust Fund Expense previously allocated to this Certificate, which
reimbursement is to occur after the date on which this Certificate is
surrendered as contemplated by the preceding sentence, will be made by check
mailed to the address of the Holder that surrenders this Certificate as such
address last appears in the Certificate Register or to any such other address of
which the Paying Agent is subsequently notified in writing.

            The Certificates are limited in right of distribution to certain

Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. With respect to the Class A-3SF

of days in the month and assuming each year has 360 days, and (2) the "Interest
Accrual Period" with respect to any Distribution Date is the period from and
including the Distribution Date in the month preceding the month in which the
related Distribution Date occurs (or, in the case of the first Distribution
Date, the Closing Date) to, but excluding, the related Distribution Date,
calculated on the basis of the actual number of days in such Interest Accrual
Period and assuming each year has 360 days; provided, however, that if a Class
A-3SF Distribution Conversion, as provided in the Agreement, has occurred, the
Interest Accrual Period for the Class A-3SF Certificates with respect to any
Distribution Date shall be the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days and each year is
assumed to consist of 360 days. Distributions in respect of the Class A-3SF
Certificates may depend, in part, on payments from the Class A-3SF Swap
Counterparty under the Class A-3SF Swap Contract as more specifically set forth
in the Agreement.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class A-3SF Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class A-3SF Certificates are exchangeable for new Class A-3SF Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-3SF Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-3SF Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-3SF Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-3SF
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-4 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-4 Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class A-4
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the

any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may

hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-4
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,

in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class A-6A Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class A-6A Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class A-6A Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class A-6A Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class A-6A Certificates are exchangeable for new Class A-6A Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-6A Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-6A Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-6A Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-6A
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-6B Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the

or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-6B
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such

successor entity under the Agreement), CWCapital Asset Management LLC (herein

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,

in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class A-7 Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class A-7 Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class A-7 Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class A-7 Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class A-7 Certificates are exchangeable for new Class A-7 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-7 Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-7 Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class A-7
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-7
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal

in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

Association (herein called the "Master Servicer," which terms include any
successor entity under the Agreement), CWCapital Asset Management LLC (herein

under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person

Distribution Date pursuant to the Agreement. Distributions in respect of the
Class A-MFL Certificates may depend, in part, on payments from the Class A-MFL

forth in the Agreement. All distributions made under the Agreement on the Class
A-MFL Certificates will be made by LaSalle Bank National Association, as paying
agent (the "Paying Agent"), by wire transfer of immediately available funds to
the account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided

to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate (determined without regard to any possible future reimbursement
of any Realized Loss or Additional Trust Fund Expense previously allocated to
this Certificate) will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution. Also notwithstanding the foregoing, any distribution that may be
made with respect to this Certificate in reimbursement of any Realized Loss or
Additional Trust Fund Expense previously allocated to this Certificate, which
reimbursement is to occur after the date on which this Certificate is
surrendered as contemplated by the preceding sentence, will be made by check
mailed to the address of the Holder that surrenders this Certificate as such
address last appears in the Certificate Register or to any such other address of
which the Paying Agent is subsequently notified in writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Class A-MFL Floating
Rate Account, the Distribution Account and, if established, the REO Account may

Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. With respect to the Class A-MFL
Certificates, (1) interest will be calculated on the basis of the actual number
of days in the month and assuming each year has 360 days, and (2) the "Interest
Accrual Period" with respect to any Distribution Date is the period from and
including the Distribution Date in the month preceding the month in which the
related Distribution Date occurs (or, in the case of the first Distribution
Date, the Closing Date) to, but excluding, the related Distribution Date,
calculated on the basis of the actual number of days in such Interest Accrual
Period and assuming each year has 360 days; provided, however, that if a Class
A-MFL Distribution Conversion, as provided in the Agreement, has occurred, the
Interest Accrual Period for the Class A-MFL Certificates with respect to any
Distribution Date shall be the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days and each year is
assumed to consist of 360 days. Distributions in respect of the Class A-MFL
Certificates may depend, in part, on payments from the Class A-MFL Swap
Counterparty under the Class A-MFL Swap Contract as more specifically set forth
in the Agreement.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class A-MFL Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class A-MFL Certificates are exchangeable for new Class A-MFL Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-MFL Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-MFL Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-MFL Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-MFL
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class A-MFX
Certificates is the calendar month preceding the month in which such
Distribution Date occurs and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class A-MFX Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class A-MFX Certificates are exchangeable for new Class A-MFX Certificates
in authorized denominations evidencing the same aggregate Percentage Interest,
as requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class A-MFX Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class A-MFX Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
A-MFX Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class A-MFX
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED

AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA
COMMERCIAL MORTGAGE SECURITIES, INC., LASALLE BANK NATIONAL ASSOCIATION, ABN
AMRO BANK N.V., WACHOVIA BANK, NATIONAL ASSOCIATION OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE
GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE REPRESENTS A
"REGULAR INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS
THOSE TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE") WITH A PASS-THROUGH RATE UNREDUCED BY THE
CLASS X-C PASS-THROUGH RATE REDUCTION PERCENTAGE.

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-C
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA
COMMERCIAL MORTGAGE SECURITIES, INC., LASALLE BANK NATIONAL ASSOCIATION, ABN
AMRO BANK N.V., WACHOVIA BANK, NATIONAL ASSOCIATION OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE
GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER
PERSON.

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE REPRESENTS A
"REGULAR INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS
THOSE TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE") WITH A PASS-THROUGH RATE UNREDUCED BY THE
CLASS X-C PASS-THROUGH RATE REDUCTION PERCENTAGE.

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-C
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED

AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA
COMMERCIAL MORTGAGE SECURITIES, INC., LASALLE BANK NATIONAL ASSOCIATION, ABN
AMRO BANK N.V., WACHOVIA BANK, NATIONAL ASSOCIATION OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE
GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER
PERSON.

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE REPRESENTS A
"REGULAR INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS
THOSE TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE") WITH A PASS-THROUGH RATE UNREDUCED BY THE
CLASS X-C PASS-THROUGH RATE REDUCTION PERCENTAGE.

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-C
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA
COMMERCIAL MORTGAGE SECURITIES, INC., LASALLE BANK NATIONAL ASSOCIATION, ABN
AMRO BANK N.V., WACHOVIA BANK, NATIONAL ASSOCIATION OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE
GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER
PERSON.

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE REPRESENTS A
"REGULAR INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS
THOSE TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE") WITH A PASS-THROUGH RATE UNREDUCED BY THE
CLASS X-C PASS-THROUGH RATE REDUCTION PERCENTAGE.

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-C
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA
COMMERCIAL MORTGAGE SECURITIES, INC., LASALLE BANK NATIONAL ASSOCIATION, ABN
AMRO BANK N.V., WACHOVIA BANK, NATIONAL ASSOCIATION OR ANY OF THEIR RESPECTIVE
AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE
GUARANTEED BY ANY AGENCY OR INSTRUMENTALITY OF THE UNITED STATES OR ANY OTHER
PERSON.

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE REPRESENTS A
"REGULAR INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS
THOSE TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE") WITH A PASS-THROUGH RATE UNREDUCED BY THE
CLASS X-C PASS-THROUGH RATE REDUCTION PERCENTAGE.

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-C
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

REVENUE CODE OF 1986 (THE "CODE") WITH A PASS-THROUGH RATE UNREDUCED BY THE

AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-C Certificate in that certain
beneficial ownership interest evidenced by all the Class X-C Certificates in the

successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-C Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-C Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-C
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-C Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-C Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-C Certificates are exchangeable for new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-C Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-C Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-C
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-C Certificate without registration or qualification. Any Class X-C
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-C Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-C Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-C
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-C
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such

Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result

registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA

AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-P
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-P Certificate in that certain
beneficial ownership interest evidenced by all the Class X-P Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-P Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-P Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-P
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-P Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-P Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-P Certificates are exchangeable for new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by

OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH

5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-P
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-P Certificate in that certain
beneficial ownership interest evidenced by all the Class X-P Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-P Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-P Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-P
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-P Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-P Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-P Certificates are exchangeable for new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

THIS CERTIFICATE DOES NOT REPRESENT AN OBLIGATION OF OR INTEREST IN WACHOVIA

AFFILIATES. NEITHER THIS CERTIFICATE NOR THE UNDERLYING MORTGAGE LOANS ARE

THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE SECURITIES ACT
OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-P
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-P Certificate in that certain
beneficial ownership interest evidenced by all the Class X-P Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage

successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-P Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-P Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-P
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-P Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-P Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-P Certificates are exchangeable for new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that

            This Certificate shall be construed in accordance with the internal

OF 1933 (THE "SECURITIES ACT") OR THE SECURITIES LAWS OF ANY STATE. ANY RESALE,
TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
REGISTRATION OR QUALIFICATION AND IN ACCORDANCE WITH THE PROVISIONS OF SECTION
5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-P
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-P Certificate in that certain
beneficial ownership interest evidenced by all the Class X-P Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as
specified above (the "Agreement"), among Wachovia Commercial Mortgage
Securities, Inc. (herein called the "Depositor", which term includes any
successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer," which terms include any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term
includes any successor entity under the Agreement) and ABN AMRO Bank N.V.
(herein called the "Fiscal Agent," which term includes any successor entity
under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class X-P Certificates on the applicable
Distribution Date pursuant to the Agreement. The Pass-Through Rate applicable to
the Class X-P Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-P
Certificates will be made by LaSalle Bank National Association, as paying agent
(the "Paying Agent"), by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Paying Agent with wiring instructions no less than five Business Days prior
to the related Record Date (which wiring instructions may be in the form of a
standing order applicable to all subsequent distributions), or otherwise by
check mailed to the address of such Certificateholder as it appears in the
Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-P Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-P Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-P Certificates are exchangeable for new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class X-P Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            The Class X-P Certificates are issuable in fully registered form
only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-P Certificates are exchangeable for new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

THIS CERTIFICATE DOES NOT HAVE A CERTIFICATE PRINCIPAL BALANCE AND WILL NOT
ENTITLE THE HOLDER HEREOF TO DISTRIBUTIONS OF PRINCIPAL, BUT IS ENTITLED TO
RECEIVE DISTRIBUTIONS OF INTEREST ONLY ON A NOTIONAL AMOUNT AS SET FORTH IN THE
AGREEMENT.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST CORPORATION, A NEW YORK CORPORATION ("DTC"), TO THE DEPOSITOR,
THE MASTER SERVICER, THE TRUSTEE, THE CERTIFICATE REGISTRAR OR ANY AGENT THEREOF
FOR REGISTRATION OF TRANSFER, EXCHANGE, OR PAYMENT, AND ANY CERTIFICATE ISSUED
IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY
AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO
SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

5.02 OF THE POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE INTERNAL
REVENUE CODE OF 1986 (THE "CODE").

BECAUSE THE COMPONENTS COMPRISING THE NOTIONAL AMOUNT OF THE CLASS X-P
CERTIFICATES WILL BE REDUCED BY ANY DISTRIBUTIONS IN REDUCTION OF THE
CERTIFICATE PRINCIPAL BALANCE OF THE CERTIFICATES RELATING TO SUCH COMPONENTS
AND BY CERTAIN LOSSES AND EXPENSES EXPERIENCED BY THE TRUST FUND WHICH ARE
ALLOCATED TO SUCH CERTIFICATES RELATING TO SUCH COMPONENTS AS SET FORTH IN THE
AGREEMENT, THE OUTSTANDING NOTIONAL AMOUNT HEREOF AT ANY TIME MAY BE LESS THAN
THE AMOUNT SHOWN ABOVE.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class X-P Certificate in that certain
beneficial ownership interest evidenced by all the Class X-P Certificates in the
Trust Fund created pursuant to a Pooling and Servicing Agreement, dated as

under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),

under the Agreement), a summary of certain of the pertinent provisions of which
is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made

if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such

the Class X-P Certificates for each Distribution Date is as provided in the
Agreement. All distributions made under the Agreement on the Class X-P
Certificates will be made by LaSalle Bank National Association, as paying agent

account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided

Certificate Register. Notwithstanding the foregoing, the final distribution on
this Certificate will be made in like manner, but only upon presentation and
surrender of this Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to the Holder hereof of such final
distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution

respect to any Distribution Date and with respect to the Class X-P Certificates
is the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

only without coupons in minimum denominations specified in the Agreement. As
provided in the Agreement and subject to certain limitations therein set forth,
the Class X-P Certificates are exchangeable for new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest, as
requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class X-P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class X-P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, or the
Certificate Registrar is obligated to register or qualify the Class X-P
Certificates under the Securities Act or any other securities law or to take any
action not otherwise required under the Agreement to permit the transfer of any
Class X-P Certificate without registration or qualification. Any Class X-P
Certificateholder desiring to effect such a transfer shall, and by the
acceptance of its Class X-P Certificate agrees to, indemnify the Trustee, the
Certificate Registrar, and the Depositor against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class X-P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class X-P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class X-P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent the rights of the Certificateholders under the Agreement at any time by
the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal

in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

            Pursuant to the terms of the Agreement, distributions will be made

if such 11th day is not a Business Day, the Business Day immediately succeeding,

collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account

Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class B Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class B Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class B Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class B
Certificates.

registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and

hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,

required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class B
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or

be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of Class C Certificates, but the Certificate Registrar may require

Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer

Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.

Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have

Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class E Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class E Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class E Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class E Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
E Certificates are exchangeable for new Class E Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class E Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class E Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class E Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class E Certificate without registration or
qualification. Any Class E Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class E Certificate agrees to, indemnify the
Trustee, the Certificate Registrar, the Paying Agent and the Depositor against
any liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class E Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class E
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class E
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

(herein called the "Master Servicer," which term includes any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer,", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class F Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class F Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class F Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class F Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
F Certificates are exchangeable for new Class F Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class F Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class F Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class F Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class F Certificate without registration or
qualification. Any Class F Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class F Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class F Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class F
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class F
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class G Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class G Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
G Certificates are exchangeable for new Class G Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class G Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class G Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class G Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class G Certificate without registration or
qualification. Any Class G Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class G Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class G Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class G
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class G
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of

authorized in writing, and thereupon one or more new Class H Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class H Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class H Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class H Certificate without registration or
qualification. Any Class H Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class H Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class H Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class H
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class H
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class J Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class J Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such

instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class J Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class J Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
J Certificates are exchangeable for new Class J Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class J Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class J Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class J Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class J Certificate without registration or
qualification. Any Class J Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class J Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class J Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class J
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class J
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class K Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class K Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such

instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class K Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class K Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
K Certificates are exchangeable for new Class K Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class K Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class K Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class K Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class K Certificate without registration or
qualification. Any Class K Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class K Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class K Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class K
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class K
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

            This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Class L Certificate (obtained by dividing
the principal amount of this Class L Certificate (its "Certificate Principal
Balance") as of the Closing Date by the aggregate principal amount of all the

any successor entity under the Agreement), Wachovia Bank, National Association
(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class L Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class L Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class L Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class L Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
L Certificates are exchangeable for new Class L Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class L Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class L Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class L Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class L Certificate without registration or
qualification. Any Class L Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class L Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class L Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class L
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class L
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class M Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class M Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
M Certificates are exchangeable for new Class M Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class M Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class M Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class M Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class M Certificate without registration or
qualification. Any Class M Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class M Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class M Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class M
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class M
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,

Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class N Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class N Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
N Certificates are exchangeable for new Class N Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class N Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class N Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class N Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class N Certificate without registration or
qualification. Any Class N Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class N Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class N Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class N
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Paying Agent, the Certificate
Registrar, or any such agent shall be affected by notice to the contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class N
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class O Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class O Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class O Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class O Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
O Certificates are exchangeable for new Class O Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class O Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class O Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, the Paying Agent or the Certificate Registrar is obligated to
register or qualify the Class O Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class O Certificate without registration
or qualification. Any Class O Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class O Certificate agrees to,
indemnify the Trustee, the Fiscal Agent, the Certificate Registrar, the Paying
Agent and the Depositor against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class O Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class O
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Paying Agent, the Certificate
Registrar, or any such agent shall be affected by notice to the contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class O
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

(herein called the "Master Servicer", which term includes any successor entity
under the Agreement), CWCapital Asset Management LLC (herein called the "Special
Servicer", which term includes any successor entity under the Agreement),
LaSalle Bank National Association (herein called the "Trustee", which term

is set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the respective meanings assigned in the Agreement. This
Certificate is issued under and is subject to the terms, provisions and
conditions of the Agreement, to which Agreement the Holder of this Certificate
by virtue of the acceptance hereof assents and by which such Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount required to be
distributed to the Holders of the Class P Certificates on the applicable
Distribution Date pursuant to the Agreement. All distributions made under the
Agreement on the Class P Certificates will be made by LaSalle Bank National
Association, as paying agent (the "Paying Agent"), by wire transfer of
immediately available funds to the account of the Person entitled thereto at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Paying Agent with wiring instructions
no less than five Business Days prior to the related Record Date (which wiring
instructions may be in the form of a standing order applicable to all subsequent
distributions), or otherwise by check mailed to the address of such
Certificateholder as it appears in the Certificate Register. Notwithstanding the
foregoing, the final distribution on this Certificate (determined without regard
to any possible future reimbursement of any Realized Loss or Additional Trust
Fund Expense previously allocated to this Certificate) will be made in like
manner, but only upon presentation and surrender of this Certificate at the
offices of the Certificate Registrar or such other location specified in the
notice to the Holder hereof of such final distribution. Also notwithstanding the
foregoing, any distribution that may be made with respect to this Certificate in
reimbursement of any Realized Loss or Additional Trust Fund Expense previously
allocated to this Certificate, which reimbursement is to occur after the date on
which this Certificate is surrendered as contemplated by the preceding sentence,
will be made by check mailed to the address of the Holder that surrenders this
Certificate as such address last appears in the Certificate Register or to any
such other address of which the Paying Agent is subsequently notified in
writing.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            Interest accrued on this Certificate during an Interest Accrual
Period, plus any unpaid interest shortfall with respect to this Certificate for
any prior Distribution Date, if any, will be payable on the related Distribution
Date to the extent provided in the Agreement. The "Interest Accrual Period" with
respect to any Distribution Date and with respect to the Class P Certificates is
the calendar month preceding the month in which such Distribution Date occurs
and is assumed to consist of 30 days.

            Any distribution to the Holder of this Certificate in reduction of
the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
distribution is made upon this Certificate.

            The Class P Certificates are issuable in fully registered form only
without coupons in minimum denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, the Class
P Certificates are exchangeable for new Class P Certificates in authorized
denominations evidencing the same aggregate Percentage Interest, as requested by
the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class P Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class P Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, Paying Agent or the Certificate Registrar is obligated to register
or qualify the Class P Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class P Certificate without registration or
qualification. Any Class P Certificateholder desiring to effect such a transfer
shall, and by the acceptance of its Class P Certificate agrees to, indemnify the
Trustee, the Fiscal Agent, the Certificate Registrar, the Paying Agent and the
Depositor against any liability that may result if the transfer is not so exempt
or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class P Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class P
Certificates.

            Notwithstanding the foregoing, for so long as this Certificate is
registered in the name of Cede & Co. or in such other name as is requested by an
authorized representative of DTC, transfers of interests in this Certificate
shall be made through the book-entry facilities of DTC.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class P
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

FOR ANY PURPOSE HEREUNDER OR UNDER THE POOLING AND SERVICING AGREEMENT REFERRED
TO HEREIN, INCLUDING, BUT NOT LIMITED TO, THE RECEIPT OF DISTRIBUTIONS ON THIS
CERTIFICATE.

            This certifies that Wachovia Bank, National Association is the
registered owner of the Percentage Interest evidenced by this Class R-I
Certificate (as specified above) in that certain beneficial ownership interest
evidenced by all the Class R-I Certificates in the Trust Fund created pursuant

"Agreement"), among Wachovia Commercial Mortgage Securities, Inc. (herein called
the "Depositor", which term includes any successor entity under the Agreement),
Wachovia Bank, National Association (herein called the "Master Servicer," which
term includes any successor entity under the Agreement), CWCapital Asset
Management LLC (herein called the "Special Servicer,", which term includes any
successor entity under the Agreement), LaSalle Bank National Association (herein
called the "Trustee", which term includes any successor entity under the
Agreement) and ABN AMRO Bank N.V. (herein called the "Fiscal Agent," which term
includes any successor entity under the Agreement), a summary of certain of the
pertinent provisions of which is set forth hereafter. To the extent not defined
herein, the capitalized terms used herein have the respective meanings assigned
in the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, distributions will be made
on the fourth Business Day following the related Determination Date (each, a
"Distribution Date"). The Determination Date is the 11th day of each month or,
if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount, if any,
required to be distributed to the Holders of the Class R-I Certificates on the
applicable Distribution Date pursuant to the Agreement. All distributions made
under the Agreement on this Class R-I Certificate will be made by check mailed
to the address of the Person entitled thereto, as such name and address appear
in the Certificate Register. Notwithstanding the foregoing, the final
distribution on this Certificate will be made in like manner, but only upon
presentation and surrender of this Certificate at the offices of the Certificate
Registrar or such other location specified in the notice to Certificateholders
of such final distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            The Class R-I Certificates are issuable in fully registered form
only without coupons in minimum denominations representing Percentage Interests
specified in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Class R-I Certificates are exchangeable for new
Class R-I Certificates in authorized denominations evidencing the same aggregate
Percentage Interest, as requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-I Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class R-I Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If a transfer of any R-I Certificate is to be
made without registration under the Securities Act (other than in connection
with the initial issuance thereof or the initial transfer thereof by the
Depositor, the Underwriters or their affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Certificate Registrar to the
effect that such transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Fiscal Agent, the Paying Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, the Fiscal
Agent, the Paying Agent or the Certificate Registrar is obligated to register or
qualify the Class R-I Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class R-I Certificate without registration or
qualification. Any Class R-I Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class R-I Certificate agrees to,
indemnify the Trustee, the Fiscal Agent, the Certificate Registrar, the Paying
Agent and the Depositor against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            No transfer of this Class R-I Certificate or any interest therein
shall be made to (A) a Plan or (B) any Person who is directly or indirectly
purchasing the Class R-I Certificate or interest therein on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan (including, without
limitation, any insurance company using assets in its general or separate
account that may constitute assets of a Plan). As a condition to its
registration of transfer of this Class R-I Certificate, the Certificate
Registrar shall have the right to require the prospective transferee of such
Certificate, if it is not a Plan or Person described in clause (B) of the
preceding sentence, to execute a certification to that effect substantially in
the form of Exhibit H to the Agreement.

            This Certificate represents the "residual interest" in REMIC I as
defined in the Agreement. Each Person who has or who acquires any Ownership
Interest in this Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the provisions of Section
5.02(d) of the Agreement and, if any purported Transferee shall become a Holder
of this Certificate in violation of the provisions of such Section 5.02(d), to
have irrevocably authorized LaSalle Bank National Association, as paying agent
(the "Paying Agent"), under clause (ii)(A) of such Section 5.02(d) to deliver
payments to a Person other than such Person and to have irrevocably authorized
the Certificate Registrar under clause (ii)(B) of such Section 5.02(d) to
negotiate the terms of any mandatory sale and to execute all instruments of
Transfer and to do all other things necessary in connection with any such sale.
Each Person holding or acquiring any Ownership Interest in this Certificate must
be a Permitted Transferee and shall promptly notify the Master Servicer, the
Paying Agent and the Certificate Registrar of any change or impending change in
its status as a Permitted Transferee. In connection with any proposed Transfer
of any Ownership Interest in this Certificate, the Certificate Registrar shall
require delivery to it, and shall not register the Transfer of this Certificate
until its receipt of, an affidavit and agreement substantially in the form
attached as Exhibit H-1 to the Agreement (a "Transfer Affidavit and Agreement")
from the proposed Transferee, in form and substance satisfactory to the
Certificate Registrar, representing and warranting, among other things, that
such Transferee is a Permitted Transferee, that it is not acquiring its
Ownership Interest in this Certificate as a nominee, trustee or agent for any
Person that is not a Permitted Transferee, that for so long as it retains its
Ownership Interest in this Certificate, it will endeavor to remain a Permitted
Transferee, and that it has reviewed the provisions of Section 5.02(d) of the
Agreement and agrees to be bound by them. Notwithstanding the delivery of a
Transfer Affidavit and Agreement by a proposed Transferee, if a Responsible
Officer of the Certificate Registrar has actual knowledge that the proposed
Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest
in this Certificate to such proposed Transferee shall be effected. The proposed
Transferee must also state in the Transfer Affidavit and Agreement that (A) it
has historically paid its debts as they have come due and intends to continue to
pay its debts as they come due in the future, (B) it understands that it may
incur tax liabilities with respect to this certificate in excess of cash flows
generated thereby, (C) it intends to pay any taxes associated with holding this
certificate as they become due, (D) it will not cause income from this
certificate to be attributable to a foreign permanent establishment or fixed
base (within the meaning of an applicable income tax treaty) of its own or of
any other person and (E) it will not transfer this certificate to any person or
entity that does not provide a similar affidavit. Any purported transfer to a
disqualified organization or other person that is not a permitted transferee or
otherwise in violation of these restrictions shall be absolutely null and void
and shall vest no rights in any purported transferee. If this certificate
represents a "non-economic residual interest", as defined in Treasury
Regulations Section 1.860E-1(c), transfers of this certificate may be
disregarded for federal income tax purposes. In order to satisfy a regulatory
safe harbor under which such transfers will not be disregarded, the transferor
may be required, among other things, to satisfy itself as to the financial
condition of the proposed transferee and either to transfer at a minimum price
or to an eligible transferee as specified in regulations.

            Each Person holding or acquiring any Ownership Interest in this
Certificate shall agree (x) to require a Transfer Affidavit and Agreement from
any other Person to whom such Person attempts to transfer its Ownership Interest
herein and (y) not to transfer its Ownership Interest unless it provides to the
Certificate Registrar a certificate substantially in the form attached as
Exhibit H-2 to the Agreement stating that, among other things, it has no actual
knowledge that such other Person is not a Permitted Transferee. Each Person
holding or acquiring an Ownership Interest in this Certificate, by purchasing
such Ownership Interest herein, agrees to give the Master Servicer and the
Paying Agent written notice that it is a "pass-through interest holder" within
the meaning of temporary Treasury Regulation Section 1.67-3T(a)(2)(i)(A)
immediately upon acquiring such Ownership Interest, if it is, or is holding such
Ownership Interest on behalf of, a "pass-through interest holder".

            The provisions of Section 5.02(d) of the Agreement may be modified,
added to or eliminated, provided that there shall have been delivered to the
Certificate Registrar and the Master Servicer the following: (a) written
confirmation from each Rating Agency to the effect that the modification of,
addition to or elimination of such provisions will not cause such Rating Agency
to qualify, downgrade or withdraw its then-current ratings of any Class Of
Certificates; and (b) an Opinion of Counsel, in form and substance satisfactory
to the Certificate Registrar and the Master Servicer, obtained at the expense of
the party seeking such modification of, addition to or elimination of such
provisions (but in no event at the expense of the Trust Fund), to the effect
that such modification of, addition to or elimination of such provisions will
not cause the Trust Fund to (x) cease to qualify as two REMICs or (y) be subject
to an entity-level tax caused by the transfer of this Class R-I Certificate to a
Person which is not a Permitted Transferee, or cause a Person other than the
prospective Transferee to be subject to a REMIC-related tax caused by the
transfer of this Class R-I Certificate to a Person which is not a Permitted
Transferee.

            A "Permitted Transferee" is any Transferee other than a Disqualified
Organization, a Plan, a Disqualified Non-United States Person or is a United
States Person with respect to whom income on this Certificate is allocable to a
foreign permanent establishment or fixed base (within the meaning of an
applicable income tax treaty) of such Person or any other United States Person.
.. A "Disqualified Organization" is any of the following: (i) the United States
or a possession thereof, any State or any political subdivision thereof, or any
agency or instrumentality of any of the foregoing (other than an instrumentality
which is a corporation if all of its activities are subject to tax and, except
for FHLMC, a majority of its board of directors is not selected by any such
governmental unit), (ii) a foreign government, international organization, or
any agency or instrumentality of either of the foregoing, (iii) any organization
(except certain farmers' cooperatives described in Section 521 of the Code)
which is exempt from the tax imposed by Chapter 1 of the Code (unless such
organization is subject to the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381 of the Code or (v) any other Person so
designated by the Paying Agent or the Certificate Registrar based upon an
Opinion of Counsel (which shall not be an expense of the Paying Agent) that the
holding of an Ownership Interest in a Class R-I Certificate by such Person may
cause the Trust Fund or any Person having an Ownership Interest in any Class of
Certificates, other than such Person, to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an Ownership Interest in a Class R-I Certificate to such Person. The terms
"United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

            A "Disqualified Non-United States Person" is any Non-United States
Person or agent thereof other than (i) a Non-United States Person that holds
this Certificate in connection with the conduct of a trade or business within
the United States and has furnished the transferor and the Certificate Registrar
with an effective IRS Form W-8ECI (or successor form) or (ii) a Non-United
States Person that has delivered to both the transferor and the Certificate
Registrar an opinion of a nationally recognized tax counsel to the effect that
the transfer of this Certificate to it is in accordance with the requirements of
the Code and the regulations promulgated thereunder and that such transfer of
this Certificate will not be disregarded for federal income tax purposes.

            A "Non-United States Person" is any Person other than a United
States Person. A "United States Person" is a citizen or resident of the United
States, a corporation or partnership (including an entity treated as a
corporation or partnership for federal income tax purposes) created or organized
in, or under the laws of the United States, any State thereof or the District of
Columbia unless in the case of a partnership, Treasury Regulations are adopted
that provide otherwise, an estate whose income is includable in gross income for
United States federal income tax purposes regardless of its source, or a trust
if a court within the United States is able to exercise primary supervision over
the administration of the trust and one or more United States Persons have the
authority to control all substantial decisions of the trust, all within the
meaning of Section 7701(a) (30) of the Code.

            No service charge will be imposed for any registration of transfer
or exchange of Class R-I Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class R-I
Certificates.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property therein. The
exercise of such right will effect early retirement of the Certificates;
however, such right to purchase is subject to the aggregate Stated Principal
Balance of the Mortgage Pool at the time of purchase being less than 1% of the
aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-Off Date
specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

if such 11th day is not a Business Day, the Business Day immediately succeeding,
commencing in September 2005 (each, a "Determination Date"). Distributions will
be made commencing on the first Distribution Date specified above, to the Person
in whose name this Certificate is registered at the close of business on the
last Business Day of the month immediately preceding the month of such
distribution (the "Record Date"), in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount, if any,
required to be distributed to the Holders of the Class R-II Certificates on the
applicable Distribution Date pursuant to the Agreement. All distributions made
under the Agreement on this Class R-II Certificate will be made by check mailed
to the address of the Person entitled thereto, as such name and address appear
in the Certificate Register. Notwithstanding the foregoing, the final
distribution on this Certificate will be made in like manner, but only upon
presentation and surrender of this Certificate at the offices of the Certificate
Registrar or such other location specified in the notice to Certificateholders
of such final distribution.

            The Certificates are limited in right of distribution to certain
collections and recoveries respecting the Mortgage Loans and REO Loans, all as
more specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Certificate Account, the Distribution Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of Advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such Advances and expenses.

            The Class R-II Certificates are issuable in fully registered form
only without coupons in minimum denominations representing Percentage Interests
specified in the Agreement. As provided in the Agreement and subject to certain
limitations therein set forth, Class R-II Certificates are exchangeable for new
Class R-II Certificates in authorized denominations evidencing the same
aggregate Percentage Interest, as requested by the Holder surrendering the same.

            As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the
Certificate Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Class R-II Certificates in
authorized denominations evidencing the same aggregate Percentage Interest will
be issued to the designated transferee or transferees.

            No transfer of any Class R-II Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the
Securities Act, and effective registration or qualification under applicable
state securities laws, or is made in a transaction which does not require such
registration or qualification. If a transfer of any R-II Certificate is to be
made without registration under the Securities Act (other than in connection
with the initial issuance thereof or the initial transfer thereof by the
Depositor, the Underwriters or their affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel satisfactory to the Certificate Registrar to the
effect that such transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust Fund or of
the Depositor, the Master Servicer, the Special Servicer, the Trustee, the
Fiscal Agent, the Paying Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective transferee on which such
Opinion of Counsel is based. None of the Depositor, the Trustee, the Fiscal
Agent, the Paying Agent or the Certificate Registrar is obligated to register or
qualify the Class R-II Certificates under the Securities Act or any other
securities law or to take any action not otherwise required under the Agreement
to permit the transfer of any Class R-II Certificate without registration or
qualification. Any Class R-II Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class R-II Certificate agrees to,
indemnify the Trustee, the Fiscal Agent, the Certificate Registrar, the Paying
Agent and the Depositor against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            No transfer of this Class R-II Certificate or any interest therein
shall be made to (A) a Plan or (B) any Person who is directly or indirectly
purchasing the Class R-II Certificate or interest therein on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan (including, without
limitation, any insurance company using assets in its general or separate
account that may constitute assets of a Plan). As a condition to its
registration of transfer of this Class R-II Certificate, the Certificate
Registrar shall have the right to require the prospective transferee of such
Certificate, if it is not a Plan or Person described in clause (B) of the
preceding sentence, to execute a certification to that effect substantially in
the form of Exhibit H to the Agreement.

            This Certificate represents the "residual interest" in REMIC II, as
defined in the Agreement. Each Person who has or who acquires any Ownership
Interest in this Certificate shall be deemed by the acceptance or acquisition of
such Ownership Interest to have agreed to be bound by the provisions of Section
5.02(d) of the Agreement and, if any purported Transferee shall become a Holder
of this Certificate in violation of the provisions of such Section 5.02(d), to
have irrevocably authorized LaSalle Bank National Association, as paying agent
(the "Paying Agent"), under clause (ii)(A) of such Section 5.02(d) to deliver
payments to a Person other than such Person and to have irrevocably authorized
the Certificate Registrar under clause (ii)(B) of such Section 5.02(d) to
negotiate the terms of any mandatory sale and to execute all instruments of
Transfer and to do all other things necessary in connection with any such sale.
Each Person holding or acquiring any Ownership Interest in this Certificate must
be a Permitted Transferee and shall promptly notify the Master Servicer, the
Paying Agent and the Certificate Registrar of any change or impending change in
its status as a Permitted Transferee. In connection with any proposed Transfer
of any Ownership Interest in this Certificate, the Certificate Registrar shall
require delivery to it, and shall not register the Transfer of this Certificate
until its receipt of, an affidavit and agreement substantially in the form
attached as Exhibit H-1 to the Agreement (a "Transfer Affidavit and Agreement")
from the proposed Transferee, in form and substance satisfactory to the
Certificate Registrar, representing and warranting, among other things, that
such Transferee is a Permitted Transferee, that it is not acquiring its
Ownership Interest in this Certificate as a nominee, trustee or agent for any
Person that is not a Permitted Transferee, that for so long as it retains its
Ownership Interest in this Certificate, it will endeavor to remain a Permitted
Transferee, and that it has reviewed the provisions of Section 5.02(d) of the
Agreement and agrees to be bound by them. Notwithstanding the delivery of a
Transfer Affidavit and Agreement by a proposed Transferee, if a Responsible
Officer of the Certificate Registrar has actual knowledge that the proposed
Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest
in this Certificate to such proposed Transferee shall be effected. The proposed
Transferee must also state in the Transfer Affidavit and Agreement that (A) it
has historically paid its debts as they have come due and intends to continue to
pay its debts as they come due in the future, (B) it understands that it may
incur tax liabilities with respect to this certificate in excess of cash flows
generated thereby, (C) it intends to pay any taxes associated with holding this
certificate as they become due, (D) it will not cause income from this
certificate to be attributable to a foreign permanent establishment or fixed
base (within the meaning of an applicable income tax treaty) of its own or of
any other person and (E) it will not transfer this certificate to any person or
entity that does not provide a similar affidavit. Any purported transfer to a
disqualified organization or other person that is not a permitted transferee or
otherwise in violation of these restrictions shall be absolutely null and void
and shall vest no rights in any purported transferee. If this certificate
represents a "non-economic residual interest", as defined in Treasury
Regulations Section 1.860E-1(c), transfers of this certificate may be
disregarded for federal income tax purposes. In order to satisfy a regulatory
safe harbor under which such transfers will not be disregarded, the transferor
may be required, among other things, to satisfy itself as to the financial
condition of the proposed transferee and either to transfer at a minimum price
or to an eligible transferee as specified in regulations.

            Each Person holding or acquiring any Ownership Interest in this
Certificate shall agree (x) to require a Transfer Affidavit and Agreement from
any other Person to whom such Person attempts to transfer its Ownership Interest
herein and (y) not to transfer its Ownership Interest unless it provides to the
Certificate Registrar a certificate substantially in the form attached as
Exhibit H-2 to the Agreement stating that, among other things, it has no actual
knowledge that such other Person is not a Permitted Transferee. Each Person
holding or acquiring an Ownership Interest in this Certificate, by purchasing
such Ownership Interest herein, agrees to give the Master Servicer and the
Paying Agent written notice that it is a "pass-through interest holder" within
the meaning of temporary Treasury Regulation Section 1.67-3T(a)(2)(i)(A)
immediately upon acquiring such Ownership Interest, if it is, or is holding such
Ownership Interest on behalf of, a "pass-through interest holder".

            The provisions of Section 5.02(d) of the Agreement may be modified,
added to or eliminated, provided that there shall have been delivered to the
Certificate Registrar and the Master Servicer the following: (a) written
confirmation from each Rating Agency to the effect that the modification of,
addition to or elimination of such provisions will not cause such Rating Agency
to qualify, downgrade or withdraw its then-current ratings of any Class Of
Certificates; and (b) an Opinion of Counsel, in form and substance satisfactory
to the Certificate Registrar and the Master Servicer, obtained at the expense of
the party seeking such modification of, addition to or elimination of such
provisions (but in no event at the expense of the Trust Fund), to the effect
that such modification of, addition to or elimination of such provisions will
not cause the Trust Fund to (x) cease to qualify as two REMICs or (y) be subject
to an entity-level tax caused by the Transfer of any Class R-II Certificate to a
Person which is not a Permitted Transferee, or cause a Person other than the
prospective Transferee to be subject to a REMIC-related tax caused by the
transfer of this Class R-II Certificate to a Person which is not a Permitted
Transferee.

            A "Permitted Transferee" is any Transferee other than a Disqualified
Organization, a Plan, a Disqualified Non-United States Person or a United States
Person with respect to whom income on this Certificate is allocable to a foreign
permanent establishment or fixed base (within the meaning of an applicable
income tax treaty) of such Person or any other United States Person. A
"Disqualified Organization" is any of the following: (i) the United States or a
possession thereof, any State or any political subdivision thereof, or any
agency or instrumentality of any of the foregoing (other than an instrumentality
which is a corporation if all of its activities are subject to tax and, except
for FHLMC, a majority of its board of directors is not selected by any such
governmental unit), (ii) a foreign government, international organization, or
any agency or instrumentality of either of the foregoing, (iii) any organization
(except certain farmers' cooperatives described in Section 521 of the Code)
which is exempt from the tax imposed by Chapter 1 of the Code (unless such
organization is subject to the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381 of the Code or (v) any other Person so
designated by the Paying Agent or the Certificate Registrar based upon an
Opinion of Counsel (which shall not be an expense of the Paying Agent) that the
holding of an Ownership Interest in a Class R-II Certificate by such Person may
cause the Trust Fund or any Person having an Ownership Interest in any Class of
Certificates, other than such Person, to incur a liability for any federal tax
imposed under the Code that would not otherwise be imposed but for the Transfer
of an Ownership Interest in a Class R-II Certificate to such Person. The terms
"United States", "State" and "international organization" shall have the
meanings set forth in Section 7701 of the Code or successor provisions.

            A "Disqualified Non-United States Person" is any Non-United States
Person or agent thereof other than (i) a Non-United States Person that holds
this Certificate in connection with the conduct of a trade or business within
the United States and has furnished the transferor and the Certificate Registrar
with an effective IRS Form W-8ECI (or successor form) or (ii) a Non-United
States Person that has delivered to both the transferor and the Certificate
Registrar an opinion of a nationally recognized tax counsel to the effect that
the transfer of this Certificate to it is in accordance with the requirements of
the Code and the regulations promulgated thereunder and that such transfer of
this Certificate will not be disregarded for federal income tax purposes.

            A "Non-United States Person" is any Person other than a United
States Person. A "United States Person" is a citizen or resident of the United
States, a corporation or partnership (including an entity treated as a
corporation or partnership for federal income tax purposes) created or organized
in, or under the laws of the United States, any State thereof or the District of
Columbia unless in the case of a partnership, Treasury Regulations are adopted
that provide otherwise, an estate whose income is includable in gross income for
United States federal income tax purposes regardless of its source, or a trust
if a court within the United States is able to exercise primary supervision over
the administration of the trust and one or more United States Persons have the
authority to control all substantial decisions of the trust, all within the
meaning of Section 7701(a) (30) of the Code.

            No service charge will be imposed for any registration of transfer
or exchange of Class R-II Certificates, but the Certificate Registrar may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any transfer or exchange of Class
R-II Certificates.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Certificates;
however, such right to purchase is subject to the aggregate Stated Principal
Balance of the Mortgage Pool at the time of purchase being less than 1% of the
aggregate Stated Principal Balance of the Mortgage Loans as of the Cut-Off Date
specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

state securities laws, or is made in a transaction which does not require such
registration or qualification. If such a transfer is to be made without
registration under the Securities Act (other than in connection with the initial
issuance thereof or the initial transfer thereof by the Depositor, the
Underwriters or their respective affiliates), then the Certificate Registrar
shall refuse to register such transfer unless it receives either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1 to the Agreement, and a
certificate from such Certificateholder's prospective transferee substantially
in the form attached as either Exhibit F-2 or Exhibit F-3 to the Agreement; or
(ii) an Opinion of Counsel reasonably satisfactory to the Certificate Registrar
to the effect that such transfer may be made without registration under the
Securities Act (which Opinion of Counsel shall not be an expense of the Trust
Fund or of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar in
their respective capacities as such), together with the written certification(s)
as to the facts surrounding such transfer from the Certificateholder desiring to
effect such transfer and/or such Certificateholder's prospective transferee on
which such Opinion of Counsel is based. None of the Depositor, the Trustee, the
Fiscal Agent, the Paying Agent or the Certificate Registrar is obligated to
register or qualify the Class Z Certificates under the Securities Act or any
other securities law or to take any action not otherwise required under the
Agreement to permit the transfer of any Class Z Certificate without registration
or qualification. Any Class Z Certificateholder desiring to effect such a
transfer shall, and by the acceptance of its Class Z Certificate agrees to,
indemnify the Trustee, the Fiscal Agent, the Certificate Registrar, the Paying
Agent and the Depositor against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

            No service charge will be imposed for any registration of transfer
or exchange of Class Z Certificates, but the Certificate Registrar may require
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed in connection with any transfer or exchange of Class Z
Certificates.

            The Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent and the Certificate Registrar and
any agent of the Depositor, the Master Servicer, the Special Servicer, the
Trustee, the Fiscal Agent, the Paying Agent or the Certificate Registrar may
treat the Person in whose name this Certificate is registered as the owner
hereof for all purposes whatsoever and none of the Depositor, the Master
Servicer, the Special Servicer, the Trustee, the Fiscal Agent, the Paying Agent,
the Certificate Registrar, or any such agent shall be affected by notice to the
contrary.

            The Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier to occur of (i) the final payment (or any advance with respect thereto)
or other liquidation of the last Mortgage Loan or REO Property remaining in the
Trust Fund, and (ii) the purchase by the Master Servicer, the Special Servicer
or the Majority Subordinate Certificateholder at a price determined as provided
in the Agreement of all Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer or the Majority Subordinate Certificateholder to purchase
from the Trust Fund all Mortgage Loans and each REO Property remaining therein.
The exercise of such right will effect early retirement of the Class Z
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1% of the aggregate Stated Principal Balance of the Mortgage Loans as of the
Cut-Off Date specified on the face hereof.

            In addition, any exchange by any Certificateholder of all of the
then outstanding Certificates (other than the Class Z, Class R-I and Class R-II
Certificates) for all of the Mortgage Loans and each REO Property remaining in
the Trust Fund may be made: (i) if the then outstanding Certificates (other than
the Class Z, Class R-I and Class R-II Certificates) are held by a single
Certificateholder and (ii) the Class A-1, Class A-2, Class A-3SF, Class A-4,
Class A-5, Class A-6A, Class A-6B, Class A-PB, Class A-7, Class A-1A, Class
A-MFL, Class A-MFX, Class A-J, Class B, Class C and Class D Certificates have
been paid in full.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the Master Servicer, the Special Servicer, the Trustee and the Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and the
Fiscal Agent with the consent of the Holders of Certificates entitled to at
least 51% of the Voting Rights allocated to the affected Classes. Any such
consent by the Holder of this Certificate shall be conclusive and binding on
such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange herefor or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, including any amendment necessary to maintain the status of the
Trust Fund (or designated portions thereof) as consisting of two separate REMICs
and three grantor trusts, without the consent of the Holders of any of the
Certificates.

            Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

            The registered Holder hereof, by its acceptance hereof, agrees that
it will look solely to the Trust Fund (to the extent of its rights therein) for
distributions hereunder.

            This Certificate shall be construed in accordance with the internal
laws of the State of New York applicable to agreements made and to be performed
in said State, and the obligations, rights and remedies of the Holder hereof
shall be determined in accordance with such laws.

            IN WITNESS WHEREOF, the Certificate Registrar has caused this
Certificate to be duly executed.

      Balance, are part of a split loan structure and the related pari passu
      companion loans are not included in the trust fund. With respect to these
      Mortgage Loans, unless otherwise specified, the calculations of LTV
      ratios, DSC ratios and Loan Amount per Unit were are based upon the
      aggregate indebtedness of these Mortgage Loans (treating the U-Haul
      Portfolio loans as a single loan) and the related pari passu companion
      loans.

(2)   Occupancy percentage calculated excluding exhibition tenant space.

(3)   In addition to any such escrows funded at loan closing for potential
      TI/LC, these Mortgage Loans require funds to be escrowed during some or
      all of the loan term for TI/LC expenses, which may be incurred during the
      loan term. In certain instances, escrowed funds may be released to the
      borrower upon satisfaction of certain leasing conditions.

(4)   Represents a future escrow commencing in May of 2006.

to the above referenced parties that, with respect to each Mortgage Loan (and
with respect to a Companion Loan, the 2005-C19 Serviced Mortgage Loan, the

Loan, only those items required pursuant to the definition of "Mortgage File")
listed in the Mortgage Loan Schedule, except as specifically identified in the
schedule of exceptions annexed thereto, (i) without regard to the proviso in the
definition of "Mortgage File," all documents specified in clauses (i), (ii),
(iv)(a), (v) and (vii), and to the extent provided in the related Mortgage File
and actually known by a Responsible Officer of the Trustee to be required,
clauses (iii), (iv)(b), (iv)(c), (vi), (viii), (ix)(a) and (xii) of the
definition of "Mortgage File" are in its possession, (ii) all documents
delivered or caused to be delivered by the applicable Mortgage Loan Seller
constituting the related Mortgage File have been reviewed by it and appear
regular on their face and appear to relate to such Mortgage Loan, (iii) based on
such examination and only as to the foregoing documents, the information set
forth in the Mortgage Loan Schedule for such Mortgage Loan with respect to the
items specified in clauses (v) and (vi) (c) of the definition of "Mortgage Loan
Schedule" is correct and (iv) solely with respect to the Companion Loans, all
documents specified in clause (xiii) of the definition of Mortgage File are in
its possession. Further, with respect to the documents described in clause
(viii) of the definition of Mortgage File, the Trustee may assume, for purposes
of the certification delivered in Section 2.02(b) of the Pooling and Servicing
Agreement and for purposes of determining (subject to the proviso at the end of

to any Mortgage Loan that has two or more Mortgagors, for each Mortgagor);
provided, however, that to the extent the Trustee has actual knowledge or is
notified of any fixture or real property UCC Financing Statements filed in the
county of the state where the related Mortgaged Property is located, the Trustee
shall file an assignment to the Trust Fund with respect to such UCC Financing
Statements in the appropriate jurisdiction under the UCC at the expense of the
related Mortgage Loan Seller. The UCC Financing Statements to be assigned to the
Trust Fund pursuant to Section 2.01(d) of the Pooling and Servicing Agreement
will be delivered by the related Mortgage Loan Seller to the Trustee on the new
national forms, in recordable form and completed pursuant to Revised Article IX
of the UCC. The Trustee will submit such UCC Financing Statements for filing in
the state of incorporation of the related Mortgagor as so indicated on the
documents provided.

            None of the Trustee, the Master Servicer, the Special Servicer or
any Custodian is under any duty or obligation to inspect, review or examine any
of the documents, instruments, certificates or other papers relating to the
Mortgage Loans delivered to it to determine that the same are valid, legal,
effective, genuine, enforceable, in recordable form, sufficient or appropriate
for the represented purpose or that they are other than what they purport to be
on their face. Capitalized terms used herein and not otherwise defined shall
have the respective meanings assigned to them under the Pooling and Servicing

                                    EXHIBIT E

                 CALCULATION OF NOI/DEBT SERVICE COVERAGE RATIOS

            "Net Cash Flow" shall mean the revenue derived from the use and
operation of a Mortgaged Property less operating expenses (such as utilities,
administrative expenses, repairs and maintenance, tenant improvement costs,
leasing commissions, management fees and advertising), fixed expenses (such as
insurance, real estate taxes and, if applicable, ground lease payments) and
replacement reserves and an allowance for vacancies and credit losses. Net Cash
Flow does not reflect interest expenses and non-cash items such as depreciation
and amortization, and generally does not reflect capital expenditures, but does
reflect reserves for replacements and an allowance for vacancies and credit
losses.

            In determining vacancy for the "revenue" component of Net Cash Flow
for each Rental Property, the Special Servicer shall rely on the most recent
rent roll supplied by the related borrower and where the actual vacancy shown
thereon and the market vacancy is less than 1%, the Special Servicer shall
assume a 1% vacancy in determining revenue from rents, except that in the case
of certain anchored shopping centers, space occupied by anchor or single tenants
or other large tenants shall be disregarded in performing the vacancy adjustment
due to the length of the related leases or creditworthiness of such tenants, in
accordance with the respective Mortgage Loan Seller's underwriting standards.
Where the actual or market vacancy was not less than 5.0%, the Special Servicer
shall determine revenue from rents by generally relying on the most recent roll
supplied and the greater of (a) actual historical vacancy at the related
Mortgaged Property, and (b) historical vacancy at comparable properties in the
same market as the related Mortgaged Property. In determining rental revenue for
multifamily, self-storage and mobile home park properties, the Special Servicer
shall either review rental revenue shown on the certified rolling 12-month
operating statements or annualized the rental revenue and reimbursement of
expenses shown on rent rolls or operating statements with respect to the prior
one to twelve month periods. For the other Rental Properties, the Special
Servicer shall annualize rental revenue shown on the most recent certified rent
roll, after applying the vacancy factor, without further regard to the terms
(including expiration dates) of the leases shown thereon. In the case of
hospitality properties, gross receipts shall be determined on the basis of
adjusted average occupancy not to exceed 75.0% and daily rates achieved during
the prior two to three year annual reporting period. In the case of residential
health care facilities, receipts shall be based on historical occupancy levels,
historical operating revenues and the then current occupancy rates. Occupancy
rates for private health care facilities shall be within current market ranges
and vacancy levels shall be at a minimum of 1%. In general, any non-recurring
items and non-property related revenue shall be eliminated from the calculation
except in the case of residential health care facilities.

            In determining the "expense" component of Net Cash Flow for each
Mortgaged Property, the Special Servicer shall rely on the rolling 12-month
operating statements and/or full-year or year-to-date financial statements
supplied by the related borrower, except that (a) if tax or insurance expense
information more current than that reflected in the financial statements is
available, the newer information shall be used, (b) with respect to each
Mortgaged Property, property management fees shall be assumed to be 3% to 7% of
effective gross revenue (except with respect to hospitality properties, where a
minimum of 3.1% of gross receipts shall be assumed, and with respect to limited
service hospitality properties, where a minimum of 4.0% of gross receipts shall
be assumed and, with respect to single tenant properties, where fees as low as
3% of effective gross receipts shall be assumed), (c) assumptions shall be made
with respect to reserves for leasing commission, tenant improvement expenses and
capital expenditures and (d) expenses shall be assumed to include annual
replacement reserves. In addition, in some instances, the Special Servicer may
recharacterize as capital expenditures those items reported by borrowers as
operating expenses (thus increasing "net cash flow") where determined
appropriate.

      of general advertising or in any other manner, or (e) taken any other
      action, which (in the case of any of the acts described in clauses (a)
      through (e) hereof) would constitute a distribution of any Certificate
      under the Securities Act of 1933, as amended (the "Securities Act"), or
      would render the disposition of any Certificate a violation of Section 5
      of the Securities Act or any state securities laws, or would require
      registration or qualification of any Certificate pursuant to the

      of general advertising or in any other manner, or (e) taken any other
      action, that (in the case of any of the acts described in clauses (a)
      through (e) above) would constitute a distribution of any Certificate
      under the Securities Act, would render the disposition of any Certificate
      a violation of Section 5 of the Securities Act or any state securities law
      or would require registration or qualification of any Certificate pursuant
      thereto. The Transferee will not act, nor has it authorized or will it
      authorize any person to act, in any manner set forth in the foregoing
      sentence with respect to any Certificate.

            6. Check one of the following:

      on the date hereof, no taxes will be required to be withheld by the
      Trustee (or its agent) with respect to distributions to be made on the
      Transferred Certificate. The Transferee has attached hereto [(i) a duly
      executed IRS Form W-8BEN (or successor form), which identifies such
      Transferee as the beneficial owner of the Transferred Certificate and
      states that such Transferee is not a U.S. Person, (ii) two duly
      executed copies of IRS Form W-8IMY (with all the appropriate
      attachments), or (iii)](1) two duly executed copies of IRS Form W-8ECI

      original issue discount on the Transferred Certificate and Permitted
      Investments is, or is expected to be, effectively connected with a U.S.

      Registrar updated [IRS Form W-8BEN, IRS Form W-8IMY or]* IRS Form
      W-8ECI, as the case may be, any applicable successor IRS forms, or such
      other certifications as the Certificate Registrar may reasonably
      request, on or before the date that any such IRS form or certification

            (a)(1) of Rule 144A pursuant to which it qualifies. Note that

      certificates of deposit, (iv) loan participations, (v) repurchase
      agreements, (vi) securities owned but subject to a repurchase agreement
      and (vii) currency, interest rate and commodity swaps. For purposes of
      determining the aggregate amount of securities owned and/or invested on a
      discretionary basis by the Transferee, the Transferee did not include any
      of the securities referred to in this paragraph.

            4. For purposes of determining the aggregate amount of securities
      owned and/or invested on a discretionary basis by the Transferee, the
      Transferee used the cost of such securities to the Transferee, unless the
      Transferee reports its securities holdings in its financial statements on
      the basis of their market value, and no current information with respect
      to the cost of those securities has been published, in which case the
      securities were valued at market. Further, in determining such aggregate
      amount, the Transferee may have included securities owned by subsidiaries
      of the Transferee, but only if such subsidiaries are consolidated with the
      Transferee in its financial statements prepared in accordance with
      generally accepted accounting principles and if the investments of such
      subsidiaries are managed under the Transferee's direction. However, such
      securities were not included if the Transferee is a majority-owned,
      consolidated subsidiary of another enterprise and the Transferee is not
      itself a reporting company under the Securities Exchange Act of 1934.

            5. The Transferee acknowledges that it is familiar with Rule 144A
      and understands that the parties to which this certification is being made
      are relying and will continue to rely on the statements made herein
      because one or more sales to the Transferee may be in reliance on Rule
      144A.

          ________         ________     Will the Transferee be purchasing the
             Yes              No        Transferred Certificate only for the
                                        Transferee's own account?

            6. If the answer to the foregoing question is "no", then in each
      case where the Transferee is purchasing for an account other than its own,
      such account belongs to a third party that is itself a "qualified
      institutional buyer" within the meaning of Rule 144A, and the "qualified
      institutional buyer" status of such third party has been established by
      the Transferee through one or more of the appropriate methods contemplated
      by Rule 144A.

            7. The Transferee will notify each of the parties to which this
      certification is made of any changes in the information and conclusions
      herein. Until such notice is given, the Transferee's purchase of the
      Transferred Certificate will constitute a reaffirmation of this
      certification as of the date of such purchase. In addition, if the
      Transferee is a bank or savings and loan as provided above, the Transferee
      agrees that it will furnish to such parties any updated annual financial
      statements that become available on or before the date of such purchase,
      promptly after they become available.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

           [For Transferees That Are Registered Investment Companies]

            The undersigned hereby certifies as follows to [name of Transferor]
(the "Transferor") and LaSalle Bank National Association, as Certificate
Registrar, with respect to the mortgage pass-through certificate being
transferred (the "Transferred Certificate") as described in the Transferee
Certificate to which this certification relates and to which this certification
is an Annex:

            1. As indicated below, the undersigned is the chief financial
      officer, a person fulfilling an equivalent function, or other executive
      officer of the entity purchasing the Transferred Certificate (the
      "Transferee") or, if the Transferee is a "qualified institutional buyer"
      as that term is defined in Rule 144A under the Securities Act of 1933
      ("Rule 144A") because the Transferee is part of a Family of Investment
      Companies (as defined below), is an executive officer of the investment
      adviser (the "Adviser").

            2. The Transferee is a "qualified institutional buyer" as defined in
      Rule 144A because (i) the Transferee is an investment company registered
      under the Investment Company Act of 1940, and (ii) as marked below, the
      Transferee alone owned and/or invested on a discretionary basis, or the
      Transferee's Family of Investment Companies owned, at least $100,000,000
      in securities (other than the excluded securities referred to below) as of
      the end of the Transferee's most recent fiscal year. For purposes of
      determining the amount of securities owned by the Transferee or the
      Transferee's Family of Investment Companies, the cost of such securities
      was used, unless the Transferee or any member of the Transferee's Family
      of Investment Companies, as the case may be, reports its securities
      holdings in its financial statements on the basis of their market value,
      and no current information with respect to the cost of those securities
      has been published, in which case the securities of such entity were
      valued at market.

      [  ]  The Transferee owned and/or invested on a discretionary basis
            $           in securities (other than the excluded securities
            referred to below) as of the end of the Transferee's most recent
            fiscal year (such amount being calculated in accordance with Rule
            144A).

      [  ]  The Transferee is part of a Family of Investment Companies which
            owned in the aggregate $            in securities (other than the
            excluded securities referred to below) as of the end of the
            Transferee's most recent fiscal year (such amount being
            calculated in accordance with Rule 144A).

            In the case of a Class R-I, Class R-II or Class Z Certificate, the
Transferee is not an "employee benefit plan" subject to Title I of ERISA or a
"plan" described by Section 4975(e)(1) of the Code or any other retirement plan
or other employee benefit plan or arrangement subject to any federal, state or
local law materially similar to the foregoing provisions of ERISA and the Code,
or any entity deemed to hold plan assets of the foregoing by reason of a plan's
investment in such entity (each, a "Plan").

            3. The term "Family of Investment Companies" as used herein means
      two or more registered investment companies (or series thereof) that have
      the same investment adviser or investment advisers that are affiliated (by
      virtue of being majority owned subsidiaries of the same parent or because
      one investment adviser is a majority owned subsidiary of the other).

            4. The term "securities" as used herein does not include (i)
      securities of issuers that are affiliated with the Transferee or are part
      of the Transferee's Family of Investment Companies, (ii) bank deposit
      notes and certificates of deposit, (iii) loan participations, (iv)
      repurchase agreements, (v) securities owned but subject to a repurchase
      agreement and (vi) currency, interest rate and commodity swaps. For
      purposes of determining the aggregate amount of securities owned and/or
      invested on a discretionary basis by the Transferee, or owned by the
      Transferee's Family of Investment Companies, the securities referred to in
      this paragraph were excluded.

            5. The Transferee is familiar with Rule 144A and understands that
      the parties to which this certification is being made are relying and will
      continue to rely on the statements made herein because one or more sales
      to the Transferee will be in reliance on Rule 144A.

              ________        ________    Will the Transferee be purchasing
                 Yes             No       the Transferred Certificate only for
                                          the Transferee's own account?

            6. If the answer to the foregoing question is "no", then in each
      case where the Transferee is purchasing for an account other than its own,
      such account belongs to a third party that is itself a "qualified
      institutional buyer" within the meaning of Rule 144A, and the "qualified
      institutional buyer" status of such third party has been established by
      the Transferee through one or more of the appropriate methods contemplated
      by Rule 144A.

            7. The undersigned will notify the parties to which this
      certification is made of any changes in the information and conclusions
      herein. Until such notice, the Transferee's purchase of the Transferred
      Certificate will constitute a reaffirmation of this certification by the
      undersigned as of the date of such purchase.

Ladies and Gentlemen:

            This letter is delivered to you in connection with the transfer by
____________________ (the "Transferor") to _______________________ (the
"Transferee") of a Certificate (the "Transferred Certificate") having an initial

The Certificates were issued pursuant to the Pooling and Servicing Agreement

Wachovia Commercial Mortgage Securities, Inc., as depositor, Wachovia Bank,
National Association, as master servicer, CWCapital Asset Management LLC, as
special servicer, LaSalle Bank National Association, as trustee, and ABN AMRO
Bank N.V., as fiscal agent. All terms used herein and not otherwise defined
shall have the meanings set forth in the Pooling and Servicing Agreement. The
Transferee hereby certifies, represents and warrants to you, as Certificate
Registrar, that:

            1. The Transferee is acquiring the Transferred Certificate for its
      own account for investment and not with a view to or for sale or transfer
      in connection with any distribution thereof, in whole or in part, in any
      manner which would violate the Securities Act of 1933, as amended (the
      "Securities Act"), or any applicable state securities laws.

            2. The Transferee understands that (a) the Certificates have not
      been and will not be registered under the Securities Act or registered or
      qualified under any applicable state securities laws, (b) neither the
      Depositor nor the Trustee or the Certificate Registrar is obligated so to
      register or qualify the Certificates and (c) the Certificates may not be
      resold or transferred unless they are (i) registered pursuant to the
      Securities Act and registered or qualified pursuant to any applicable
      state securities laws or (ii) sold or transferred in transactions which
      are exempt from such registration and qualification and the Certificate
      Registrar has received either (A) certifications from both the transferor
      and the transferee (substantially in the forms attached to the Pooling and
      Servicing Agreement) setting forth the facts surrounding the transfer or
      (B) an opinion of counsel satisfactory to the Certificate Registrar with
      respect to the availability of such exemption (which Opinion of Counsel
      shall not be an expense of the Trust Fund or of the Depositor, the Master
      Servicer, the Special Servicer, the Trustee or the Certificate Registrar
      in their respective capacities as such), together with copies of the
      certification(s) from the Transferor and/or Transferee setting forth the
      facts surrounding the transfer upon which such opinion is based. Any
      holder of a Certificate desiring to effect such a transfer shall, and upon
      acquisition of such Certificate shall be deemed to have agreed to,
      indemnify the Master Servicer, the Special Servicer, Trustee, the
      Certificate Registrar and the Depositor against any liability that may
      result if the transfer is not so exempt or is not made in accordance with
      such federal and state laws.

            3. The Transferee understands that it may not sell or otherwise
      transfer any portion of its interest in the Transferred Certificate except
      in compliance with the provisions of Section 5.02 of the Pooling and
      Servicing Agreement, which provisions it has carefully reviewed, and that
      the Transferred Certificate will bear legends substantially to the
      following effect (provided that the Class E, Class F, Class G, Class H,
      Class X-C and Class X-P Certificates will bear a legend substantially to
      the effect of the following first paragraph only):

      THE CERTIFICATE HAS NOT BEEN AND WILL NOT BE REGISTERED OR QUALIFIED UNDER
      THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE

      Certificate, any interest in any Certificate or any other similar security
      to any person in any manner, (b) solicited any offer to buy or accept a

      Certificate, any interest in any Certificate or any other similar security
      with any person in any manner, (d) made any general solicitation by means
      of general advertising or in any other manner, or (e) taken any other
      action, that (in the case of any of the acts described in clauses (a)
      through (e) above) would constitute a distribution of any Certificate
      under the Securities Act, would render the disposition of any Certificate
      a violation of Section 5 of the Securities Act or any state securities law
      or would require registration or qualification of any Certificate pursuant
      thereto. The Transferee will not act, nor has it authorized or will it
      authorize any person to act, in any manner set forth in the foregoing
      sentence with respect to any Certificate.

            5. The Transferee has been furnished with all information regarding

COUNTY OF MECKLENBURG   )

            [NAME OF OFFICER], being first duly sworn, deposes, and represents
and warrants:

            1. That he is a [Title of Officer] of [Name of Owner] (the "Owner"),
      a corporation duly organized and existing under the laws of the [State of
      ___________] [the United States], and the owner of the Wachovia Commercial
      Mortgage Securities, Inc., Commercial Mortgage Pass-Through Certificates,
      Series 2005-C20, Class [R-I] [R-II] evidencing a ___% Interest in the

      Bank, National Association, as master servicer, CWCapital Asset Management
      LLC, as special servicer, LaSalle Bank National Association, as trustee,
      and ABN AMRO Bank N.V., as fiscal agent.

            2. That the Owner (i) is and will be a "Permitted Transferee" as of
      ________, _______ and (ii) is acquiring the Class [R-I] [R-II]
      Certificates for its own account or for the account of another Owner from
      which it has received an affidavit in substantially the same form as this
      affidavit. A "Permitted Transferee" is any person other than a
      Disqualified Organization, a Plan, or a Disqualified Non-United States
      Person or a United States Person with respect to whom income on the Class
      [R-I][R-II] Certificate is allocable to a foreign permanent establishment
      or fixed base, within the meaning of an applicable income tax treaty, of
      such Person or any other United States Person. For this purpose, a
      "Disqualified Organization" means any of the following: (i) the United
      States or a possession thereof, any State or any political subdivision
      thereof, or any agency or instrumentality of any of the foregoing (other
      than an instrumentality which is a corporation if all of its activities
      are subject to tax and, except for FHLMC, a majority of its board of
      directors is not selected by any such governmental unit), (ii) a foreign
      government, international organization, or any agency or instrumentality
      of either of the foregoing, (iii) any organization (except certain
      farmers' cooperatives described in Section 521 of the Internal Revenue
      Code of 1986, as amended (the "Code")) which is exempt from the tax
      imposed by Chapter 1 of the Code (unless such organization is subject to
      the tax imposed by Section 511 of the Code on unrelated business taxable
      income), (iv) rural electric and telephone cooperatives described in
      Section 1381 of the Code or (v) any other Person so designated by the
      Trustee or the Certificate Registrar based upon an Opinion of Counsel that
      the holding of an Ownership Interest in a Class [R-I] [R-II] Certificate
      by such Person may cause the Trust Fund or any Person having an Ownership
      Interest in any Class of Certificates, other than such Person, to incur a
      liability for any federal tax imposed under the Code that would not
      otherwise be imposed but for the Transfer of an Ownership Interest in a
      Class [R-I] [R-II] Certificate to such Person. The terms "United States",
      "State" and "international organization" shall have the meanings set forth
      in Section 7701 of the Code or successor provisions.

            A "Disqualified Non-United States Person" is any Person (i) other
      than a United States Person that holds the Class[R-I] [R-II] Certificate
      in connection with the conduct of a trade or business within the United
      States and has furnished the transferor and the Certificate Registrar with
      an effective IRS Form W-8ECI (or successor form) or that has delivered to
      both the transferor and the Certificate Registrar an opinion of a
      nationally recognized tax counsel to the effect that the transfer of the
      Class [R-I] [R-II] Certificate to it is an accordance with the
      requirements of the Code and the regulations promulgated thereunder and
      that such transfer of the Class [R-I] [R-II] Certificate will not be
      disregarded for federal income tax purposes or (ii) who is a United States
      Person with respect to whom income on the Class [R-I] [R-II] Certificate
      is allocable to a foreign permanent establishment or fixed base (within
      the meaning of an applicable income tax treaty) of such Person or any
      other United States Person. A "United States Person" is a citizen or
      resident of the United States, a corporation or partnership (including an
      entity treated as a corporation or partnership for federal income tax
      purposes) created or organized in, or under the laws of the United States,
      any State thereof or the District of Columbia unless, in the case of a
      partnership, Treasury Regulations are adopted that provide otherwise, an
      estate whose income is includable in gross income for United States
      federal income tax purposes regardless of its source, or a trust if a
      court within the United States is able to exercise primary supervision
      over the administration of the trust and one or more United States Persons
      have the authority to control all substantial decisions of the trust, all
      within the meaning of Section 7701(a)(30) of the Code.

            3. That the Owner is aware (i) of the tax that would be imposed on
      transfers of the Class [R-I] [R-II] Certificates to Disqualified
      Organizations under the Code that applies to all transfers of the Class
      [R-I] [R-II] Certificates after March 31, 1988; (ii) that such tax would
      be on the transferor, or, if such transfer is through an agent (which
      person includes a broker, nominee or middleman) for a Disqualified
      Organization Transferee, on the agent; (iii) that the person otherwise
      liable for the tax shall be relieved of liability for the tax if the
      transferee furnishes to such person an affidavit that the transferee is
      not a Disqualified Organization and, at the time of transfer, such person
      does not have actual knowledge that the affidavit is false; and (iv) that
      the Class [R-I] [R-II] Certificates may be "non-economic residual
      interests" within the meaning of Treasury regulation section
      1.860E-1(c)(2) and that the transferor of a "non-economic residual
      interest" will remain liable for any taxes due with respect to the income
      on such residual interest, unless no significant purpose of the transfer
      is to enable the transferor to impede the assessment or collection of tax.

            4. That the Owner is aware of the tax imposed on a "pass-through
      entity" holding the Class [R-I] [R-II] Certificates if at any time during
      the taxable year of the pass-through entity a non-Permitted Transferee is
      the record holder of an interest in such entity. For this purpose, a "pass
      through entity" includes a regulated investment company, a real estate
      investment trust or common trust fund, a partnership, trust or estate, and
      certain cooperatives.

            5. That the Owner is aware that the Certificate Registrar will not
      register the transfer of any Class [R-I] [R-II] Certificate unless the
      transferee, or the transferee's agent, delivers to the Trustee, among
      other things, an affidavit in substantially the same form as this
      affidavit. The Owner expressly agrees that it will not consummate any such
      transfer if it knows or believes that any of the representations contained
      in such affidavit and agreement are false.

            6. That the Owner consents to any additional restrictions or
      arrangements that shall be deemed necessary upon advice of counsel to
      constitute a reasonable arrangement to ensure that the Class [R-I] [R-II]
      Certificates will only be owned, directly or indirectly, by Permitted
      Transferees.

            7. That the Owner's taxpayer identification number is _____________.

            8. That the Owner has reviewed the restrictions set forth on the
      face of the Class [R-I] [R-II] Certificates and the provisions of Section
      5.02 of the Pooling and Servicing Agreement under which the Class [R-I]
      [R-II] Certificates were issued (and, in particular, the Owner is aware
      that such Section authorizes the Trustee to deliver payments to a person
      other than the Owner and negotiate a mandatory sale by the Trustee in the
      event that the Owner holds such Certificate in violation of Section 5.02);
      and that the Owner expressly agrees to be bound by and to comply with such
      restrictions and provisions.

            9. That the Owner is not acquiring and will not transfer the Class
      [R-I] [R-II] Certificates in order to impede the assessment or collection
      of any tax.

            10. That the Owner has historically paid its debts as they have come
      due, intends to continue to pay its debts as they come due in the future,
      and anticipates that it will, so long as it holds any of the Class [R-I]
      [R-II] Certificates, have sufficient assets to pay any taxes owed by the
      holder of such Class [R-I] [R-II] Certificates.

            11. That the Owner has no present knowledge that it may become
      insolvent or subject to a bankruptcy proceeding for so long as it holds
      any of the Class [R-I] [R-II] Certificates.

            12. That the Owner has no present knowledge or expectation that it
      will be unable to pay any United States taxes owed by it so long as any of
      the Certificates remain outstanding. In this regard, the Owner hereby
      represents to and for the benefit of the Person from whom it acquired the
      Class [R-I] [R-II] Certificates that the Owner intends to pay taxes
      associated with holding the Class [R-I] [R-II] Certificates as they become
      due, fully understanding that it may incur tax liabilities in excess of
      any cash flows generated by the Class [R-I] [R-II] Certificates.

            13. That the Owner is not acquiring the Class [R-I] [R-II]
      Certificates with the intent to transfer any of the Class [R-I] [R-II]
      Certificates to any person or entity that will not have sufficient assets
      to pay any taxes owed by the holder of such Class [R-I] [R-II]
      Certificates, or that may become insolvent or subject to a bankruptcy
      proceeding, for so long as the Class [R-I] [R-II] Certificates remain
      outstanding.

            14. That the Owner will, in connection with any transfer that it
      makes of the Class [R-I] [R-II] Certificates, obtain from its transferee
      the representations required by Section 5.02(d) of the Pooling and
      Servicing Agreement under which the Class [R-I] [R-II] Certificates were
      issued and will not consummate any such transfer if it knows, or knows
      facts that should lead it to believe, that any such representations are
      false.

            15. That the Owner will, in connection with any transfer that it
      makes of any Class [R-I] [R-II] Certificate, deliver to the Certificate
      Registrar an affidavit, which represents and warrants that it is not
      transferring such Class [R-I] [R-II] Certificate to impede the assessment
      or collection of any tax and that it has no actual knowledge that the
      proposed transferee: (i) has insufficient assets to pay any taxes owed by
      such transferee as holder of such Class [R-I] [R-II] Certificate; (ii) may
      become insolvent or subject to a bankruptcy proceeding, for so long as the
      Class [R-I] [R-II] Certificates remain outstanding; and (iii) is not a
      "Permitted Transferee".

            16. Check the applicable paragraph:

            [ ] The present value of the anticipated tax liabilities associated
with holding the [R-I] [R-II] Certificate, as applicable, does not exceed the
sum of:

            (i)   the present value of any consideration given to the Owner to
                  acquire such [R-I] [R-II] Certificate;

            (ii)  the present value of the expected future distributions on such
                  [R-I] [R-II] Certificate; and

            (iii) the present value of the anticipated tax savings associated
                  with holding such [R-I] [R-II] Certificate as the related
                  REMIC generates losses.

            For purposes of this calculation, (i) the Owner is assumed to pay
tax at the highest rate currently specified in Section 11(b) of the Code (but
the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the
highest rate specified in Section 11(b) of the Code if the Owner has been
subject to the alternative minimum tax under Section 55 of the Code in the
preceding two years and will compute its taxable income in the current taxable
year using the alternative minimum tax rate) and (ii) present values are
computed using a discount rate equal to the short-term Federal rate prescribed
by Section 1274(d) of the Code for the month of the transfer and the compounding
period used by the Owner.

            [ ] The transfer of the [R-I] [R-II] Certificate complies with U.S.

            evidencing a ____% percentage interest in the Class to which they
            belong

Dear Sirs:

            This letter is delivered to you in connection with the transfer by
_________ (the "Transferor") to ______________________ (the "Transferee") of the
captioned Class [R-I] [R-II] Certificates (the "Class [R-I] [R-II]
Certificates"), pursuant to Section 5.02 of the Pooling and Servicing Agreement
(the "Pooling and Servicing Agreement"), dated as of August 1, 2005, among
Wachovia Commercial Mortgage Securities, Inc., as depositor, Wachovia Bank,
National Association, as master servicer, CWCapital Asset Management LLC, as
special servicer, LaSalle Bank National Association, as trustee and ABN AMRO
Bank N.V., as fiscal agent. All terms used herein and not otherwise defined
shall have the meanings set forth in the Pooling and Servicing Agreement. The
Transferor hereby represents and warrants to you, as Certificate Registrar,
that:

            1. No purpose of the Transferor relating to the transfer of the
      Class [R-I] [R-II] Certificates by the Transferor to the Transferee is or
      will be to impede the assessment or collection of any tax.

            2. The Transferor understands that the Transferee has delivered to
      you a Transfer Affidavit and Agreement in the form attached to the Pooling
      and Servicing Agreement as Exhibit H-1. The Transferor does not know or
      believe that any representation contained therein is false.

            3. The Transferor at the time of this transfer has conducted a
      reasonable investigation of the financial condition of the Transferee as
      contemplated by Treasury regulation section 1.860E-1(c)(4)(i) and, as a
      result of that investigation, the Transferor has determined that the
      Transferee has historically paid its debts as they became due and has
      found no significant evidence to indicate that the Transferee will not
      continue to pay its debts as they become due in the future.

            4. The Transferor understands that the transfer of the Class [R-I]
      [R-II] Certificates may not be respected for United States income tax
      purposes (and the Transferor may continue to be liable for United States
      income taxes associated therewith) unless the test described above in
      Paragraph 3 has been met as to any transfer.

                                       Very truly yours,

            Reference is made to the Pooling and Servicing Agreement described
above. Capitalized terms used but not defined herein have the meanings assigned
to such terms in the Pooling and Servicing Agreement.

            As Master Servicer under the Pooling and Servicing Agreement, we
hereby:

            (a) Notify you that the Mortgagor has consummated a defeasance of
the Mortgage Loan pursuant to the terms of the Mortgage Loan, of the type
checked below:

            ____  a full defeasance of the entire principal balance of the

            ____  a partial defeasance of a portion of the principal balance
            of the Mortgage Loan that represents and, an allocated loan
            amount of $____________ or _______% of the entire principal
            balance of the Mortgage Loan;

            (b) Certify that each of the following is true, subject to those
exceptions set forth with explanatory notes on Exhibit A hereto, which
exceptions the Master Servicer has determined, consistent with the Servicing
Standard, will have no material adverse effect on the Mortgage Loan or the
defeasance transaction:

            (ii)  The Mortgage Loan documents permit the defeasance, and the
                  terms and conditions for defeasance specified therein were
                  satisfied in all material respects in completing the
                  defeasance.

            (iii) The defeasance was consummated on __________, 20__.

            (iv)  The defeasance collateral consists of securities that (i)
                  constitute "government securities" as defined in Section
                  2(a)(16) of the Investment Company Act of 1940 as amended (15
                  U.S.C. 80A1), (ii) are listed as "Qualified Investments for
                  `AAA' Financings" under Paragraphs 1, 2 or 3 of "Cash Flow
                  Approach" in Standard & Poor's Public Finance Criteria 2000,
                  as amended to the date of the defeasance, (iii) are rated
                  `AAA' by S&P, (iv) if they include a principal obligation, the
                  principal due at maturity cannot vary or change, and (v) are
                  not subject to prepayment, call or early redemption.

            (v)   The Master Servicer received an opinion of counsel (from
                  counsel approved by Master Servicer in accordance with the
                  Servicing Standard) that the defeasance will not result in an
                  Adverse REMIC Event.

            (vi)  The Master Servicer determined that the defeasance collateral
                  will be owned by an entity (the "Defeasance Obligor") that is
                  a Single-Purpose Entity (as defined in Standard & Poor's
                  Structured Finance Ratings Real Estate Finance Criteria, as
                  amended to the date of the defeasance (the "S&P Criteria")) as
                  of the date of the defeasance, and after the defeasance owns
                  no assets other than the defeasance collateral and real
                  property securing Mortgage Loans included in the pool.

            (vii) The Master Servicer received written confirmation of the
                  crediting of the defeasance collateral to an Eligible Account
                  (as defined in the S&P Criteria) in the name of the Defeasance
                  Obligor, which account is maintained as a securities account
                  by a securities intermediary and has been pledged to the
                  Trustee.

            (viii) The agreements executed in connection with the defeasance (i)
                  grant control of the pledged securities account to the
                  Trustee, (ii) require the securities intermediary to make the
                  scheduled payments on the Mortgage Loan from the proceeds of
                  the defeasance collateral directly to the Servicer's
                  collection account in the amounts and on the dates specified
                  in the Mortgage Loan documents or, in a partial defeasance,
                  the portion of such scheduled payments attributed to the
                  allocated loan amount for the real property defeased,
                  increased by any defeasance premium specified in the Mortgage
                  Loan documents (the "Scheduled Payments"), (iii) permit
                  reinvestment of proceeds of the defeasance collateral only in
                  Permitted Investments (as defined in the S&P Criteria), (iv)
                  permit release of surplus defeasance collateral and earnings
                  on reinvestment from the pledged securities account only after
                  the Mortgage Loan has been paid in full, if any such release
                  is permitted, (v) prohibit transfers by the Defeasance Obligor
                  of the defeasance collateral and subordinate liens against the
                  defeasance collateral, and (vi) provide for payment from
                  sources other than the defeasance collateral or other assets
                  of the Defeasance Obligor of all fees and expenses of the
                  securities intermediary for administering the defeasance and
                  the securities account and all fees and expenses of
                  maintaining the existence of the Defeasance Obligor.

            (ix)  The Master Servicer received written confirmation from a firm
                  of independent certified public accountants, who were approved
                  by Master Servicer in accordance with the Servicing Standard
                  stating that (i) revenues from the defeasance collateral
                  (without taking into account any earnings on reinvestment of
                  such revenues) will be sufficient to timely pay each of the
                  Scheduled Payments after the defeasance including the payment
                  in full of the Mortgage Loan (or the allocated portion thereof
                  in connection with a partial defeasance) on its Maturity Date
                  (or, in the case of an ARD Loan, on its Anticipated Repayment
                  Date), (ii) the revenues received in any month from the
                  defeasance collateral will be applied to make Scheduled
                  Payments within four (4) months after the date of receipt, and
                  (iii) interest income from the defeasance collateral to the
                  Defeasance Obligor in any calendar or fiscal year will not
                  exceed such Defeasance Obligor's interest expense for the
                  Mortgage Loan (or the allocated portion thereof in a partial
                  defeasance) for such year.

            (x)   The Mortgage Loan is not among the ten (10) largest loans in
                  the pool. The entire principal balance of the Mortgage Loan as
                  of the date of defeasance was less than both $[______] and
                  five percent of the pool balance, which is less than [__]% of
                  the aggregate Certificate Balance of the Certificates as of
                  the date of the most recent Trustee's Distribution Date
                  Statement received by us (the "Current Report").

            (xi)  The defeasance described herein, together with all prior and
                  simultaneous defeasances of Mortgage Loans, brings the total
                  of all fully and partially defeased Mortgage Loans to
                  $__________________, which is _____% of the aggregate
                  Certificate Balance of the Certificates as of the date of the
                  Current Report.

            (c) Certify that Exhibit B hereto is a list of the material
agreements, instruments, organizational documents for the Defeasance Obligor,
and opinions of counsel and independent accountants executed and delivered in
connection with the defeasance.

            (d) Certify that the individual under whose hand the Master Servicer
has caused this Notice and Certification to be executed did constitute a
Servicing Officer as of the date of the defeasance described above.

            (e) Agree to provide copies of all items listed in Exhibit B to you
upon request.

that they will rely upon this certification (capitalized terms used herein

            1. I have reviewed the servicing reports relating to the Trust
      delivered by the master servicer to the trustee pursuant to the pooling
      and servicing agreement covering the fiscal year [_____];

      my knowledge and the annual compliance review required under Section 3.13
      of the pooling and servicing agreement with respect to the master
      servicer, and except as disclosed in the compliance certificate delivered
      by the master servicer under Section 3.13 of the pooling and servicing
      agreement, the master servicer has fulfilled its obligations under the
      pooling and servicing agreement; and

respect to Mortgage Information that, on or before five days prior to the
Determination Date for the related servicing report, (a) the master servicer has
been notified in writing by a party to the pooling and servicing agreement, any
mortgage loan seller (as defined in the pooling and servicing agreement), or any
affiliate thereof, was incorrect or (b) the master servicer would have known was

servicing agreement in accordance with the servicing standards (as defined in

if Employee should accept other employment after the Separation Date, otherwise in accordance with
this Agreement.

     6. Securities and Tax Considerations.

          (a) Internal Revenue Code Section 409A. Notwithstanding anything in this Agreement to
the contrary, the parties hereby agree that it is the intention that any payments or benefits
provided under this Agreement comply in all respects with Section 409A of the Internal Revenue Code
of 1986, as amended (“Code”) and any guidance issued thereunder, and this Agreement be interpreted
accordingly. In addition, in the event that additional guidance with respect to Section 409A of
the Code becomes available, the Company agrees that, upon Employee’s reasonable request, it will
amend this Agreement solely to the extent necessary and appropriate to avoid adverse tax
consequences pursuant to Section 409A of the Code. The Company agrees that it shall not do anything
to cause Employee to become subject to any penalty or additional taxes under Section 409A of the
Code with respect to any Company compensation or benefits. In addition, the Company agrees that it
shall take all necessary action so that Employee never becomes subject to any penalty or additional
taxes under Section 409A of the Code with respect to any Company compensation or benefits.

          (b) The Company agrees to cooperate as reasonably necessary and appropriate with respect to
any equity compensation instructions issued by Employee’s broker or authorized representative,
subject in all respects to applicable federal, state, local or self regulatory entity securities
laws, rules and/or regulations.

     7. Employee Covenants.

          (a) Unauthorized Disclosure. Employee shall not, during the term of this Agreement
and thereafter, make any Unauthorized Disclosure. For purposes of this Agreement, “Unauthorized
Disclosure” shall mean disclosure by Employee without the prior
written consent of the Board to any person, other than an employee of the Company or a person to
whom disclosure is reasonably necessary or appropriate in connection with the performance by
Employee of his duties as an executive officer of the Company, of any confidential information
relating to the business or prospects of the Company including, but not limited to, any

4

 

EXECUTION COPY

confidential information with respect to any of the Company’s customers, products, methods of
distribution, strategies, business and marketing plans and business policies and practices,
litigation strategies or defenses, and plans for new business concepts;, except (i) to the extent
disclosure is or may be required by law, by a court of law or by any governmental agency or other
person or entity with apparent jurisdiction to require him to divulge, disclose or make available
such information or (ii) in confidence to an attorney or other advisor for the purpose of securing
professional advice concerning Employee’s personal matters provided such attorney or other advisor
agrees to observe these confidentiality provisions. Unauthorized Disclosure shall not include the
use or disclosure by Employee, without consent, of any information known generally to the public or
known within the Company’s trade or industry (other than as a result of disclosure by him in
violation of this Paragraph 7(a)). This confidentiality covenant has no temporal, geographical or
territorial restriction.

          (b) Non-Competition. During the Non-Competition/No-Raid Period described below,
Employee shall not, directly or indirectly, without the prior written consent of the Company, own,
manage, operate, join, control, be employed by, consult with or participate in the ownership,
management, operation or control of, or be connected with (as a stockholder, partner, or otherwise)
the following companies: American Eagle Outfitters, Gap Inc., J Crew, Aero Postale or Limited
Brands, or any of their affiliates in substantially the same markets and market segments as the
foregoing companies; provided, however, that the “beneficial ownership” (as that term is defined in
Rule 13d-3 under the Exchange Act) by Employee after his termination of employment with the
Company, either individually or as a member of a “group” for purposes of Section 13(d)(3) under the
Exchange Act and the regulations promulgated thereunder, of not more than two percent (2%) of the
voting stock of any of these corporations which are publicly held shall not be a violation of this
Agreement.

          (c) Non-Solicitation. During the Non-Competition/No-Raid Period described below,
Employee shall not, either directly or indirectly, alone or in conjunction with another person,
interfere with or harm, or attempt to interfere with or harm, the relationship of the Company, its
subsidiaries and/or affiliates, with any person who at any time was an employee, customer or
supplier of the Company, its subsidiaries and/or affiliates or otherwise had a business
relationship with the Company, its subsidiaries and/or affiliates.

          (d) Non-Competition/No-Raid Period. For purposes of this Agreement, the
“Non-Competition/No-Raid Period” means the one-year period immediately following the Separation
Date.

          (e) Remedies. Employee agrees that any breach of the terms of this Paragraph 7 or of
Paragraph 9 of this Agreement would result in irreparable injury and damage to the Company for
which the Company would have no adequate remedy at law; Employee therefore also agrees that in the
event of said breach or any threat of breach, the Company shall
be entitled to an immediate injunction and restraining order to prevent such breach and/or
threatened breach and/or continued breach by Employee and/or any and all persons and/or entities
acting for and/or with Employee, without having to prove damages, in addition to any other remedies
to which the Company may be entitled at law or in equity. The terms of this

5

 

EXECUTION COPY

Paragraph 7(e) shall
not prevent the Company from pursuing any other available remedies for any breach or threatened
breach hereof, including, but not limited to the recovery of damages from Employee. Employee and
the Company further agree that the provisions of the covenants not to compete and solicit are
reasonable and that the Company would not have entered into this Agreement but for the inclusion of
such covenants herein. Should a court or arbitrator determine, however, that any provision of the
covenants is unreasonable, either in period of time, geographical area, or otherwise, the parties
hereto agree that the covenants should be interpreted and enforced to the maximum extent which such
court or arbitrator deems reasonable. The provisions of this Paragraph shall survive any
termination of this Agreement, and the existence of any claim or cause of action by Employee
against the Company, whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by the Company of the covenants and agreements of Paragraph 7(a);
provided, however, that this paragraph shall not, in and of itself, preclude Employee from
defending himself against the enforceability of the covenants and agreements of Paragraph 7(a). The
Company hereby waives any right it might have to claim that Employee should be precluded from
accepting employment or otherwise providing services on the basis that such employment or
performance of services will inevitably result in unauthorized disclosure in violation of Paragraph
7(a); this waiver shall not preclude the Company from asserting any claim for damages it may have
for a violation of Paragraph 7(a), nor from seeking equitable relief to enjoin Employee from making
actual disclosures in violation of Paragraph 7(a).

     8. Indemnification.

          (a) The Company agrees that if Employee is made a party, or is threatened to be made a party,
to any action, suit or proceeding, whether civil, criminal, administrative or investigative (a
“Proceeding”), by reason of the fact that he is or was a director, officer or employee of the
Company or is or was serving at the request of the Company as a director, officer, member, employee
or agent of another corporation, partnership, joint venture, trust or other enterprise, including
service with respect to employee benefit plans, whether or not the basis of the Proceeding is
Employee’s alleged action in an official capacity while serving as a director, officer, member,
employee or agent, Employee shall be indemnified and held harmless by the Company to the fullest
extent legally permitted or authorized by the Company’s certificate of incorporation or bylaws or
resolutions of the Company’s Board or, if greater, by the laws of the State of Delaware, against
all cost, expense, liability and loss (including, without limitation, attorneys’ fees, judgments,
fines, ERISA excise taxes or other liabilities or penalties and amounts paid or to be paid in
settlement) reasonably incurred or suffered by Employee in connection therewith, and such
indemnification shall continue as to Employee even if he has ceased to be a director, member,
employee or agent of the Company or other entity and shall inure to the benefit of Employee’s
heirs, executors and administrators. The Company shall advance to Employee all costs and expenses
incurred by him in connection with a Proceeding within 20 calendar days after receipt by the
Company of a written request for such advance. Such request shall include an
undertaking by Employee to repay the amount of such advance if it shall ultimately be determined
that he is not entitled by law to be indemnified against such costs and expenses; provided that the
amount of such obligation to repay shall be limited to the after-tax amount of

6

 

EXECUTION COPY

any such advance
except to the extent Employee is able to offset such taxes incurred on the advance by the tax
benefit, if any, attributable to a deduction realized by him for the repayment.

          (b) Neither the failure of the Company (including its Board, independent legal counsel or
stockholders) to have made a determination prior to the commencement of any Proceeding concerning
payment of amounts claimed by Employee under Paragraph 8(a) above that indemnification of Employee
is proper because he has met the applicable standard of conduct, nor a determination by the Company
(including its Board, independent legal counsel or stockholders) that Employee has not met such
applicable standard of conduct, shall create a presumption in any judicial proceeding that Employee
has not met the applicable standard of conduct.

          (c) The Company agrees to continue and maintain a directors’ and officers’ liability insurance
policy covering Employee, until such time as actions against Employee are no longer permitted by
law, with terms and conditions no less favorable than the most favorable coverage then applying to
any other senior level executive officer or director of the Company.

     9. Cooperation and Non-Disparagement. Neither Employee nor any officer, director or any
other authorized spokesperson of the Company shall state or otherwise publish anything about the
other party which would adversely affect the reputation, image or business relationships and
goodwill of the other party in its/his market and community at large. Employee shall fully
cooperate with the Company in defense of legal claims asserted against the Company and other
matters requiring the testimony or input and knowledge of Employee, and the Company agrees to
reimburse Employee for reasonable costs and expenses incurred as a result thereof. Employee agrees
that he will not speak or communicate with any party or representative of any party, who is known
to Employee to be either adverse to the Company in litigation or administrative proceedings or to
have threatened to commence litigation or administrative proceedings against the Company, with
respect to the pending or threatened legal action, unless given express permission to do so by the
Company, or is otherwise compelled by law to do so, and then only after advance notice to the
Company. Additionally, for a period of one year following the Separation Date, Employee agrees to
be bound by and follow the same standards and duty of loyalty to the Company as are required of the
Company’s employees and officers, except that Employee may engage in other employment or
business-related activities so long as such activities do not violate Paragraph 7 of this
Agreement.

     10. Certain Additional Payments.

          (a) In the event it shall be determined that any payment, benefit or distribution of any type
to or for the benefit of Employee by the Company, any of its affiliates, or any person who acquires
ownership or effective control of the Company or ownership of a substantial portion of the
Company’s assets (within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the “Code”), and the regulations thereunder) or any
affiliate of such person, whether paid or payable, received or receivable, or distributed or
distributable pursuant to the terms of this Agreement or otherwise (the “Total Payments”), is or
would be

EXECUTION COPY

subject to the excise tax imposed by Section 4999 of the Code or any similar successor
provision or any interest or penalties with respect to such excise tax (such excise tax, together
with any such interest and penalties, are collectively referred to as the “Excise Tax”), then
Employee shall be entitled to receive an additional payment (the “Gross-Up Payment”) in an amount
such that after payment by Employee of all taxes (including any interest or penalties imposed with
respect to such taxes), including any Excise Tax, imposed upon the Gross-Up Payment, Employee
retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Total Payments
(not including the Gross-Up Payment).

          (b) All determinations as to whether any of the Total Payments are “parachute payments”
(within the meaning of Section 280G of the Code), whether a Gross-Up Payment is required, the
amount of such Gross-Up Payment and any amounts relevant to the last sentence of Paragraph 10 (a)
above, shall be made by an independent accounting firm selected by the Company from among the
largest four accounting firms in the United States (the “Accounting Firm”). Unless Employee agrees
otherwise in writing, the Accounting Firm cannot during the two years preceding the date of its
selection have acted in any way on behalf of the Company or any of its affiliates. The Accounting
Firm shall provide its determination (the “Determination”), together with detailed supporting
calculations, regarding the amount of any Gross-Up Payment and any other relevant matter, both to
the Company and Employee, at such time as is requested by the Company or Employee (if Employee
reasonably believes that any of the Total Payments may be subject to the Excise Tax). Any
determination by the Accounting Firm shall be binding upon the Company and Employee. As a result
of uncertainty in the application of Section 4999 of the Code at the time of the initial
determination by the Accounting Firm hereunder, it may be determined that the Company should have
made Gross-Up Payments (“Underpayment”), or that Gross-Up Payments will have been made by the
Company which should not have been made (“Overpayment”). In either such event, the Accounting Firm
shall determine the amount of the Underpayment or Overpayment that has occurred. In the case of an
Underpayment, the amount of such Underpayment shall be promptly paid by the Company to or for the
benefit of Employee. In the case of an Overpayment, Employee shall, at the direction and expense
of the Company, take such steps as are reasonably necessary (including the filing of returns and
claims for refund), follow reasonable instructions from, and procedures established by, the
Company, and otherwise reasonably cooperate with the Company to correct such Overpayment. Employee
and the Company shall each reasonably cooperate with the other in connection with any
administrative or judicial proceedings concerning the existence or amount of liability for Excise
Tax with respect to the Total Payments.

     11. Release of All Claims.

          (a) Release of Company by Employee. In consideration of the receipt of the sums and
covenants stated herein, Employee does hereby, on behalf of himself, his heirs, administrators,
executors, agents, and assigns, forever release, requite, and discharge the Company and its agents,
parents, subsidiaries, affiliates, divisions, officers, directors, employees,
predecessors, successors, and assigns (“Released Parties”), from any and all charges, claims,
demands, judgments, actions, causes of action, damages, expenses, costs, attorneys’ fees, and
liabilities of any kind whatsoever, whether known or unknown, vested or contingent, in law,

equity or otherwise, which Employee has ever had, now has, or may hereafter have against said Released
Parties for or on account of any matter, cause or thing whatsoever which has occurred prior to the

generality of the foregoing, any and all claims which are related to Employee’s employment with the
Company and his resignation from his officer position and his employment on August [31]. 2005, and
his resignation from the Board on or before September 1, 2005; and any and all rights which

Retirement Income Security Act, 29 U.S.C. §1001 et seq.; the Americans With
Disabilities Act; the Age Discrimination in Employment Act, as amended; Ohio Revised Code Section
4112.01 et seq.; and all other federal, state, and local statutes, regulations or
public policies, as well as the laws of contract, torts, and all other subjects; provided, however,
that nothing herein shall be deemed to affect any rights of Employee under this Agreement or to any
pension, employee welfare benefits, stock options, or restricted shares which were vested on or
prior to the Separation Date or Effective Date, as applicable, and pursuant to this Agreement; and
provided further that nothing herein shall be deemed to affect any rights of Employee to indemnity
for liabilities incurred for acts taken in good faith in the course and scope of employment with
the Company and for such acts otherwise covered under the terms and conditions of Directors and
Officers liability insurance maintained by Company during the employment of Employee.

          (b) Age Discrimination Claims and Older Worker’s Benefit Protection Act Terms.
Employee specifically acknowledges that the release of his claims under this Agreement includes,
without limitation, waiver and release of all claims against the Company and Released Parties under
the federal Age Discrimination in Employment Act (“ADEA”), and Employee further acknowledges and
agrees that:

	 	i.	 	Employee waives his claims under ADEA
knowingly and voluntarily in exchange for the commitments made
herein by the Company, and that certain of the benefits
provided thereby constitute consideration of value to which
Employee would not otherwise have been entitled;
	 
	 	ii.	 	Employee was and is hereby advised to
consult an attorney in connection with this Agreement;
	 
	 	iii.	 	Employee has been given a period of 21

predecessors, successors and assigns, forever release, requite, and discharge Employee and his
heirs, administrators, executors, agents and assigns, from any and all charges, claims, demands,
judgments, actions, causes of action, damages, expenses, costs, attorneys’ fees, and liabilities of
any kind whatsoever, whether known or unknown, vested or contingent, in law, equity or otherwise,
which the Company ever had, now has, or may hereafter have against Employee for or on account of
any matter, cause or thing whatsoever which has occurred prior to the date of Employee’s signing
this Agreement; provided, however, that nothing herein shall be deemed to release or affect any
rights of the Company pursuant to this Agreement.

     12. Complete and Absolute Defense. This Agreement constitutes, among other things, a full
and complete release of any and all claims released by either party, and it is the intention of the

any claims against the other which are released hereunder, and covenant not to sue the other party
or Released Parties based upon any claims released hereunder. The parties further represent and
warrant that no charges, claims or suits of any kind have been filed by either against the other as
of the date of this Agreement.

     13. Non-Admission. It is understood that this Agreement is, among other things, an
accommodation of the desires of each party, and the above-mentioned payments and covenants are not,
and should not be construed as, an admission or acknowledgment by either party of any liability
whatsoever to the other party or any other person or entity.

     14. Return of Property. Employee agrees that on or before his Separation Date or as soon
as feasible thereafter, he shall promptly return to the Company all Company documents and property
in his possession or control including, but not limited to, Personal Computer(s) and all Software,
Security Keys and Badges, Price Lists, Supplier and Customer Lists, Files, Reports, all
correspondence both internal and external (memo’s, letters, quotes, etc.), Business Plans, Budgets,
Designs, and any and all other property of the Company; and the Company shall promptly return to
Employee his personal property and files.

     15. Knowing and Voluntary Execution. Each of the parties hereto further states and
represents that he or it has carefully read the foregoing Agreement, consisting of 13 pages, and
knows the contents thereof, and that he or it has executed the same as his or its own free act and
deed. Employee further acknowledges that he has been and is hereby advised to
consult with an attorney concerning this Agreement and that he had adequate opportunity to seek the
advice of legal counsel in connection with this Agreement. Employee also acknowledges that

10

he has had the opportunity to ask questions about each and every provision of this Agreement and that he
fully understands the effect of the provisions contained herein upon his legal rights.

     16. Executed Counterparts. This Agreement may be executed in one or more counterparts, and
any executed copy of this Agreement, including by facsimile, shall be valid and have the same force
and effect as the originally-executed Agreement.

     17. Governing Law. This Agreement shall be governed by, and construed and enforced in
accordance with, the laws of the State of Ohio.

unless such waiver, modification or discharge is agreed to in writing and signed by Employee and
the Company.

     19. Assignability. Employee’s obligations and agreements under this Agreement shall be
binding on Employee’s heirs, executors, legal representatives and assigns and shall inure to the
benefit of any successors and assigns of the Company. The Company may assign this Agreement or any
of its rights or obligations arising hereunder to any party, as part of a sale of substantially all
of its assets or other significant change of control.

     20. Entire Agreement. This Agreement constitutes the entire agreement between the parties
hereto in respect of the subject matter hereof, and this Agreement supersedes all prior and
contemporaneous agreements between the parties hereto in connection with the subject matter hereof.
