            The Depositor intends to sell commercial mortgage pass-through

purposes as a "real estate mortgage investment conduit" (a "REMIC").

respect to each Corrected Loan.

            "Workout Fee Rate":  As defined in Section 3.11(b).

            "Yield Maintenance Charge": With respect to any Loan, the yield
maintenance charge set forth in the related Loan, including but not limited to a
yield maintenance charge which is based on the amount of Defeasance Collateral.
If a Yield Maintenance Charge becomes due for any particular Loan, the Servicer
shall be required to follow the terms and provisions contained in the applicable
Loan Documents; provided, however, that if the related Loan Documents do not
specify which U.S. Treasury obligations are to be used in determining the
discount rate or the reinvestment yield to be applied in such calculation, or if
the related Loan Documents are ambiguous, the Servicer shall be required to use
those U.S. Treasury obligations that will generate the lowest discount rate or
reinvestment yield for the purposes thereof. Accordingly, if either no U.S.
Treasury obligation, or more than one U.S. Treasury obligation, coincides with
the term over which the Yield Maintenance Charge is to be calculated (which,
depending on the applicable Loan Documents, is based on the remaining average
life of the Loan or the actual term remaining through the Maturity Date), the
Servicer shall use the U.S. Treasury obligations 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 becomes 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 = (12 x [{(1+BEY/2)1/6}-1]) x 100
where BEY is defined as the U.S. Treasury Reinvestment Yield in decimal, not
percentage, form, 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 +
0.055/2) 0.16667}-1]) x 100, where 0.055 is the decimal version of the

apply:

            (i) All calculations of interest with respect to the Loans (other
      than the Actual/360 Loans) and of Advances provided for herein shall be
      made on the basis of a 360-day year consisting of twelve 30-day months.

      respect to the calculation of interest accruing at the related Mortgage
      Rate.

            (ii) Any Loan payment is deemed to be received on the date such
      payment is actually received by the Servicer, the Special Servicer or the
      Trustee; provided, however, that for purposes of calculating distributions
      on the Certificates, (i) any voluntary Principal Prepayment made on a date
      other than the related Due Date and in connection with which the Servicer
      has collected interest thereon through the end of the related Mortgage
      Interest Accrual Period shall be deemed to have been made, and the

      principal balance of the related Loan as if such Principal Prepayment had
      been received, on the following Due Date and (ii) all other Principal
      Prepayments with respect to any Loan are deemed to be received on the date
      they are applied to reduce the outstanding principal balance of such Loan.

      Certificates on or as of a Distribution Date shall refer to the
      Certificate Balance of such Class of Certificates on such Distribution
      Date after giving effect to (a) any distributions made on such
      Distribution Date pursuant to Section 4.01(a), (b) any Collateral Support
      Deficit allocated to such Class on such Distribution Date pursuant to
      Section 4.04 and (c) the addition of any Certificate Deferred Interest
      allocated to such Class and added to such Certificate Balance pursuant to
      Section 4.06(b) (except that no such increase in Certificate Balance
      pursuant to this clause (c) shall count for the purposes of determining
      Voting Rights or the identity of the Controlling Class).

                              CONVEYANCE OF LOANS;
                        ORIGINAL ISSUANCE OF CERTIFICATES

            Section 2.01      Conveyance of Loans.

            (a) The Depositor, concurrently with the execution and delivery
hereof, does hereby assign, sell, transfer, set over and otherwise convey to the
Trustee, without recourse, for the benefit of the Certificateholders all the
right, title and interest of the Depositor, including any security interest
therein for the benefit of the Depositor, in, to and under (i) the Loans
identified on the Mortgage Loan Schedule, (ii) the Mortgage Loan Purchase
Agreements (including rights under the FINOVA Mortgage Loan Purchase Agreements
assigned under the MS Mortgage Loan Purchase Agreement) 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
Loans (other than payments of principal and interest due and payable on the
Loans on or before the Cut-off Date and Principal Prepayments paid on or before
the Cut-off Date). The transfer of the Loans and the related rights and property
accomplished hereby is absolute and, notwithstanding Section 10.07, is intended
by the parties to constitute a sale.

            (b) In connection with the Depositor's assignment pursuant to
subsection (a) above, the Depositor shall direct, and hereby represents and
warrants that it has directed each Mortgage Loan Seller pursuant to the related
Mortgage Loan Purchase Agreement to deliver to and deposit with, or cause to be
delivered to and deposited with, the Custodian, on behalf of the Trustee (with a
copy to the Trustee, the Servicer and the Special Servicer), on or before the
Closing Date, the Mortgage File for each Loan so assigned. If a Mortgage Loan
Seller cannot deliver, or cause to be delivered as to any Loan, the original
Note, such Mortgage Loan Seller shall deliver a copy or duplicate original of
such Note, together with an affidavit substantially in the form attached as
Exhibit K hereto, certifying that the original thereof has been lost or
destroyed.

            If the applicable Mortgage Loan Seller cannot deliver, or cause to
be delivered, as to any Loan, any of the documents and/or instruments referred
to in clauses (ii), (iv), (vi), (viii), (xi) and (xii) 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 this Section 2.01(b) shall be deemed to have been
satisfied 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 such Mortgage Loan Seller to
be a true and complete copy of the original thereof submitted for recording) is
delivered to the Custodian, on behalf of the Trustee, and the Servicer on or
before the Closing Date, and either the original of such non-delivered document
or instrument, or a photocopy thereof (certified by the appropriate county
recorder's office to be a true and complete copy of the original thereof
submitted for recording), with evidence of recording thereon, is delivered to
the Custodian within 120 days of the Closing Date, which period may be extended
up to two times, in each case for an additional period of 45 days provided that
such Mortgage Loan Seller, as certified in writing to the Custodian prior to
each such 45-day extension, 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 Loan, any of the documents and/or instruments referred
to in clauses (ii), (iv), (vi), (viii), (xi) and (xii) of the definition of
"Mortgage File," 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 related Mortgage Loan Purchase
Agreement and this Section 2.01(b) shall be deemed to have been satisfied and
such non-delivered document or instrument shall be deemed to have been included
in the Mortgage File if a photocopy of such non-delivered document or instrument
(with evidence of recording thereon and certified by the appropriate county
recorder's office to be a true and complete copy of the original thereof
submitted for recording) is delivered to the Custodian and to the Servicer on or
before the Closing Date.

            Neither the Trustee nor the Custodian shall be liable for any
failure by either Mortgage Loan Seller or the Depositor to comply with the
delivery requirements of the related Mortgage Loan Purchase Agreement and this
Section 2.01(b). Notwithstanding the foregoing, if either Mortgage Loan Seller
fails to deliver a UCC-2 or UCC-3 on or before the Closing Date as required
above solely because the related UCC-1 has not been returned to such Mortgage
Loan Seller by the applicable filing office, such Mortgage Loan Seller shall not
be in breach of its obligations with respect to such delivery, provided that the
Mortgage Loan Seller promptly forwards such UCC-1 to the Servicer (with a copy
to the Custodian) upon its return, together with the related original UCC-2 or
UCC-3 in a form appropriate for filing.

            (c) At the expense of the related Mortgage Loan Seller, the
Custodian shall, as to each Loan, use its best efforts to promptly (and in any
event no later than the later of (i) 90 days after the Closing Date and (ii) 60
days from receipt of documents in recordable form, including, without
limitation, all necessary recording and filing information) cause to be
submitted for recording or filing, as the case may be, each assignment referred
to in clauses (ii), (iii), (iv), (v) and (vii) of the definition of "Mortgage
File" and each UCC-2 or UCC-3 referred to in clause (xi) of the definition of
"Mortgage File." Each such assignment shall reflect that it should be returned
by the public recording office to the Custodian following recording, and each
such UCC-2 or UCC-3 shall reflect that the file copy thereof should be returned
to the Custodian following filing. If any such document or instrument is lost or
returned unrecorded or unfiled because of a defect therein, the Custodian shall
prepare or cause to be prepared a substitute therefor or cure such defect, as
the case may be, and thereafter the Custodian shall upon receipt thereof cause
the same to be duly recorded or filed, as appropriate. Within 30 days following
request therefor, the Depositor shall reimburse the Custodian for all of its
costs and expenses incurred in performing its obligation under this Section
2.01(c).

            (d) All documents and records in the Depositor's or the applicable
Mortgage Loan Seller's possession relating to the Loans (including reserve and
escrow agreements, cash management agreements, lockbox agreements, financial
statements, operating statements and any other information provided by the
respective Mortgagor from time to time) that are not required to be a part of a
Mortgage File in accordance with the definition thereof shall be delivered to
the Servicer within 30 days of the Closing Date and shall be held by the
Servicer on behalf of the Trustee in trust for the benefit of the
Certificateholders.

            (e) In connection with the Depositor's assignment pursuant to
subsection (a) above, the Depositor shall deliver, and hereby represents and
warrants that it has delivered, to the Custodian and the Servicer, on or before
the Closing Date, a fully executed original counterpart of each of the Mortgage
Loan Purchase Agreements, as in full force and effect, without amendment or
modification, on the Closing Date.

            (f) The Depositor shall use its best efforts to require that,
promptly after the Closing Date, but in all events within three Business Days
after the Closing Date, each of the Mortgage Loan Sellers shall cause all funds
on deposit in escrow accounts maintained with respect to the Loans in the name
of such Mortgage Loan Seller or any other name to be transferred to the Servicer
(or a Sub-Servicer at the direction of the Servicer) for deposit into Servicing
Accounts.

            (g) Each of the Exchange Apartments Loan and the L'Enfant
Participation is secured by a Mortgaged Property which serves as security for
the Trust Fund Note and the related Other Note. With respect to the L'Enfant
Participation, the related Other Note is included in a trust fund (the "Other
Trust Fund") created in connection with issuance of the Depositor's Commercial
Mortgage Pass-Through Certificates, Series 1998-C2.

            Section 2.02      Acceptance by Custodian.

            (a) The Custodian, on behalf of the Trustee, by the execution and
delivery of this Agreement, acknowledges receipt by it, subject to the
provisions of Sections 2.01 and 2.02(d), to any exceptions noted on the
Custodian Exception Report, and to the further review provided for in Section
2.02(b), of the Notes, fully executed original counterparts of the Mortgage Loan
Purchase Agreements and of all other assets included in the Trust Fund, in good
faith and without notice of any adverse claim, and declares that it holds and
will hold such documents and any other documents delivered or caused to be
delivered by the Mortgage Loan Sellers constituting the Mortgage Files, and that
it holds and will hold such other assets included in the Trust Fund, in trust
for the exclusive use and benefit of all present and future Certificateholders.

            (b) Within 90 days of the Closing Date, the Custodian shall review
and, subject to Sections 2.01 and 2.02(d), certify in writing to each of the
Depositor, the Servicer, the Special Servicer, the Trustee and the applicable
Mortgage Loan Seller that, as to each Loan listed in the Mortgage Loan Schedule
(other than any Loan paid in full or any Loan specifically identified in any
exception report annexed thereto as not being covered by such certification),
(i) all documents specified in clauses (i) through (v), (ix), (xi) and (xii) of
the definition of "Mortgage File" are in its possession, and (ii) all documents
delivered or caused to be delivered by such Mortgage Loan Seller constituting
the Mortgage Files have been received, have been executed, appear to be what
they purport to be, purport to be recorded or filed (if recordation or filing is
specified for such document in the definition of "Mortgage File") and have not
been torn, mutilated or otherwise defaced, and that such documents relate to the
Loans identified on the Mortgage Loan Schedule.

            (c) The Custodian shall review each of the Loan Documents received
after the Closing Date; and, on or about 90 days following the Closing Date, 180
days following the Closing Date, the first anniversary of the Closing Date, 180
days following the first anniversary of the Closing Date, 270 days following the
first anniversary of the Closing Date and on the second anniversary of the
Closing Date, the Custodian shall, subject to Sections 2.01 and 2.02(d), certify
in writing to each of the Depositor, the Servicer, the Special Servicer, the
Trustee and the Mortgage Loan Seller that, as to each Loan listed on the
Mortgage Loan Schedule (other than any Loan as to which a Liquidation Event has
occurred or any Loan specifically identified in any exception report annexed
thereto as not being covered by such certification), (i) all documents specified
in clauses (i) through (v), (ix), (xi) and (xii) of the definition of "Mortgage
File" are in its possession, (ii) it has received either a recorded original of
each of the assignments specified in clause (iii) and clause (v) of the
definition of "Mortgage File," insofar as an unrecorded original thereof had
been delivered or caused to be delivered by the applicable Mortgage Loan Seller
or a copy of such recorded original certified by the applicable public recording
office to be true and complete, and (iii) all such Loan Documents have been
received, have been executed, appear to be what they purport to be, purport to
be recorded or filed (if recordation or filing is specified for such document in
the definition of "Mortgage File") and have not been torn, mutilated or
otherwise defaced, and that such documents relate to the Loans identified on the
Mortgage Loan Schedule. The Custodian shall provide the Servicer with recording
and filing information as to recorded Mortgages, Assignment of Lease and UCC
financing statements promptly after the Custodian receives them from the related
recording offices.

            (d) It is herein acknowledged that the Custodian is not under any
duty or obligation (i) to determine whether any of the documents specified in
clauses (vi), (vii), (viii), (x), (xiii) through (xxiii) of the definition of
"Mortgage File" exist or are required to be delivered by the Depositor, a
Mortgage Loan Seller or any other Person other than to the extent identified on
the related Mortgage Loan Schedule, (ii) to inspect, review or examine any of
the documents, instruments, certificates or other papers relating to the Loans
delivered to it to determine that the same are valid, legal, effective, in
recordable form, genuine, enforceable, sufficient or appropriate for the
represented purpose or that they are other than what they purport to be on their
face or (iii) to determine whether any omnibus assignment specified in clause
(vii) of the definition of "Mortgage File" is effective under applicable law.

            (e) If, in the process of reviewing the Mortgage Files or at any
time thereafter, the Custodian finds that (a) any document required to be
included in the Mortgage File is not in its possession or (b) such document has
not been properly executed or is otherwise defective on its face (each, a
"Defect" in the related Mortgage File), the Custodian shall promptly so notify
the Depositor, the Servicer, the Special Servicer, the Trustee and the Mortgage
Loan Sellers, by providing a written report (the "Custodian Exception Report")
setting forth for each affected Loan, with particularity, the nature of such
Defect. The Custodian shall not be required to verify the conformity of any
document with the Mortgage Loan Schedule, except that such documents have been
properly executed or received, have been recorded or filed (if recordation is
specified for such document in the definition of "Mortgage File"), appear to be
related to the Loans identified on the Mortgage Loan Schedule, appear to be what
they purport to be, or have been torn, mutilated or otherwise defaced.

            (f) Upon the second anniversary of the Closing Date, the Custodian
shall deliver a final exception report as to any remaining Defects or required
Loan Documents that are not in its possession.

            (g) Upon becoming aware of a Defect (including through notice from
the Custodian or any other party hereto), the Servicer shall cause the
applicable Mortgage Loan Seller to either: (i) cause such Defect or Loan
Document deficiency to be cured in accordance with the applicable Mortgage Loan
Purchase Agreement; (ii) cause to be delivered to the Custodian an Opinion of
Counsel to the effect that such Defect or Loan Document deficiency will not have
a material adverse effect upon the value of the related Loan or the
Certificateholders' interest therein; or (iii) repurchase the related Loan
pursuant to Section 2.03 and the applicable Mortgage Loan Purchase Agreement.

of the  Depositor;  Repurchase  of Loans by the  Mortgage  Loan  Sellers,
FINOVA and FINOVA  Capital for Defects in Mortgage  Files and  Breaches of
Representations and Warranties.

            (a) The Depositor hereby represents and warrants that:

               (i)  The Depositor is a corporation duly organized, validly
      existing and in good standing under the laws of the State of Delaware, and
      the Depositor has taken all necessary corporate action to authorize the
      execution, delivery and performance of this Agreement by it, and has the
      power and authority to execute, deliver and perform this Agreement and all
      the transactions contemplated hereby, including, but not limited to, the
      power and authority to sell, assign and transfer the Loans in accordance
      with this Agreement;

               (ii) Assuming the due authorization, execution and delivery of
      this Agreement by each other party hereto, this Agreement and all of the
      obligations of the Depositor hereunder are the legal, valid and binding
      obligations of the Depositor, enforceable against the Depositor in
      accordance with the terms of this Agreement, except as such enforcement
      may be limited by bankruptcy, insolvency, reorganization or other similar
      laws affecting the enforcement of creditors' rights generally, and by
      general principles of equity (regardless of whether such enforceability is
      considered in a proceeding in equity or at law);

               (iii) The execution and delivery of this Agreement and the
      performance of its obligations hereunder by the Depositor will not
      conflict with any provisions of any law or regulations to which the
      Depositor is subject, or conflict with, result in a breach of or
      constitute a default under any of the terms, conditions or provisions of
      the certificate of incorporation or the by-laws of the Depositor or any
      indenture, agreement or instrument to which the Depositor is a party or by
      which it is bound, or any order or decree applicable to the Depositor, or
      result in the creation or imposition of any lien on any of the Depositor's
      assets or property, which would materially and adversely affect the
      ability of the Depositor to carry out the transactions contemplated by
      this Agreement; the Depositor has obtained any consent, approval,
      authorization or order of any court or governmental agency or body
      required for the execution, delivery and performance by the Depositor of
      this Agreement;

               (iv) There is no action, suit or proceeding pending or, to the
      Depositor's knowledge, threatened against the Depositor in any court or by
      or before any other governmental agency or instrumentality which would
      materially and adversely affect the validity of the Loans or the ability
      of the Depositor to carry out the transactions contemplated by this
      Agreement;

               (v)  The Depositor is the lawful owner of the Loans with the full
      right to transfer the Loans to the Trust Fund and upon the assignment of
      the Loans to the Trust, the Loans will be validly transferred to the
      Trust;

               (vi) Following consummation of the conveyance of the Loans by the
      Depositor to the Trustee, the Depositor shall take no action inconsistent
      with the Trust Fund's ownership of the Loans, and if a third party,
      including a potential purchaser of the Loans, should inquire, the
      Depositor shall promptly indicate that the Loans have been sold and shall
      claim no ownership interest therein; and

               (vii) Each Loan is a "qualified mortgage" within the meaning of
      Code Section 860G(a)(3) (but without regard to the rule in Treasury
      Section 1.860G-2(f)(2) that treats a defective obligation as a qualified
      mortgage).

            (b) If any Certificateholder, the Servicer, the Special Servicer,
the Certificate Administrator, the Custodian or the Trustee discovers or
receives notice of a breach of any representation or warranty set forth in, or
required to be made with respect to a Loan by any Mortgage Loan Seller, FINOVA
or FINOVA Capital pursuant to the related Mortgage Loan Purchase Agreement or
related FINOVA Mortgage Loan Purchase Agreement, as applicable (a "Breach"),
which Breach materially and adversely affects the value of any Loan or the
interests of the Certificateholders therein, such Certificateholder, the
Servicer, the Special Servicer, the Certificate Administrator, the Custodian or
the Trustee, as applicable, shall give prompt written notice of such Breach to
the Depositor, the Certificate Administrator, the Trustee, the Servicer, the
Special Servicer, the applicable Mortgage Loan Seller and, in the event of a
Breach by FINOVA or FINOVA Capital, to FINOVA and FINOVA Capital, and shall
request that (A) such Mortgage Loan Seller, FINOVA or FINOVA Capital, as
applicable, or (B) in the event the CSFB Mortgage Loan Seller shall fail to act,
Credit Suisse First Boston, acting through the Cayman Branch, not later than (i)
the earlier of 90 days from the receipt by the applicable Mortgage Loan Seller,
FINOVA or FINOVA Capital of such notice or discovery by such Mortgage Loan
Seller, FINOVA or FINOVA Capital of such Breach and (ii) in the case of the
FINOVA Loans, the expiration of an additional 90 days, if granted by the Trustee
in accordance with the terms of the FINOVA Mortgage Loan Purchase Agreements,
cure such Breach in all material respects or repurchase the affected Loan at the
applicable Purchase Price or in conformity with the related Mortgage Loan
Purchase Agreement.

            If any Certificateholder, the Servicer, the Special Servicer, the
Certificate Administrator, the Custodian or the Trustee discovers or receives
notice of a Defect in any Mortgage File, which Defect materially and adversely
affects the value of any Loan or the interests of the Certificateholders
therein, such Certificateholder, the Servicer, the Special Servicer, the
Certificate Administrator, the Custodian or the Trustee, as applicable, shall
give prompt written notice of such Defect to the Depositor, the Certificate
Administrator, the Trustee, the Servicer, the Special Servicer and the
applicable Mortgage Loan Seller and shall request that (i) such Mortgage Loan
Seller or (ii) in the event the CSFB Mortgage Loan Seller shall fail to act,
Credit Suisse First Boston, acting through the Cayman Branch, not later than the
earlier of 90 days from the receipt by such Mortgage Loan Seller of such notice
or discovery by such Mortgage Loan Seller of such Defect, cure such Defect in
all material respects or repurchase the affected Loan at the applicable Purchase
Price or in conformity with the Mortgage Loan Purchase Agreement.

            Any Defect or Breach which causes any Loan not to be a "qualified
mortgage" (within the meaning of Section 860G(a)(3) of the Code) shall be deemed
to materially and adversely affect the interest of Certificateholders therein.
If the affected Loan is to be repurchased, the Trustee shall designate the
Collection Account as the account into which funds in the amount of the Purchase
Price are to be deposited by wire transfer.

            In connection with any repurchase of a Loan contemplated by this
Section 2.03, the Custodian, the Servicer and the Special Servicer shall each
tender to the related Mortgage Loan Seller (in the event of a repurchase by a
Mortgage Loan Seller), FINOVA or FINOVA Capital (in the event of a repurchase by
FINOVA or FINOVA Capital), or the holder of the Exchange Apartments Other Note
(in the event of a repurchase of the Exchange Apartments Trust Fund Note
pursuant to the related Co-Lender Agreement) upon delivery to each of the
Custodian, the Servicer and the Special Servicer of a trust receipt executed by
such Mortgage Loan Seller, FINOVA or FINOVA Capital, or the holder of the
Exchange Apartments Other Note, as applicable, all portions of the Mortgage File
and other documents pertaining to such Loan possessed by it, and each document
that constitutes a part of the Mortgage File that was endorsed or assigned to
the Trustee, shall be endorsed or assigned, as the case may be, to such Mortgage
Loan Seller, FINOVA or FINOVA Capital, or the holder of the Exchange Apartments
Other Note, as applicable, in the same manner as provided in Section 7 of the
related Mortgage Loan Purchase Agreement or Section 9.3 of the related FINOVA
Mortgage Loan Purchase Agreement, respectively.

            Section 7 of the Mortgage Loan Purchase Agreements and Section 9.3
of the FINOVA Mortgage Loan Purchase Agreements provides the sole remedy
available to the Certificateholders, or the Trustee on behalf of the
Certificateholders, respecting any Breach. Section 7 of the Mortgage Loan
Purchase Agreements provides the sole remedy available to the
Certificateholders, or the Trustee on behalf of the Certificateholders,
respecting any Defect.

            If a Mortgage Loan Seller, FINOVA or FINOVA Capital defaults on its
obligations to repurchase any Loan as contemplated by Section 2.03(b), the
Trustee shall promptly notify the Certificateholders, the Certificate
Administrator, the Rating Agencies, the Servicer and the Special Servicer of
such default. The Trustee shall enforce the obligations of the Mortgage Loan
Sellers under Section 7 of the related Mortgage Loan Purchase Agreement, and of
FINOVA and FINOVA Capital under Section 9.3 of the related FINOVA Mortgage Loan
Purchase Agreement. Such enforcement, including, without limitation, the legal
prosecution of claims, shall be carried out in such form, to such extent and at
such time as if it were, in its individual capacity, the owner of the affected
Loan(s). The Trustee shall be reimbursed for the reasonable costs of such
enforcement: first, from a specific recovery of costs, expenses or attorneys'
fees against the defaulting Mortgage Loan Seller, FINOVA or FINOVA Capital;
second, pursuant to Section 3.05(a)(vii) out of the related Purchase Price, to
the extent that such expenses are a specific component thereof; and third, if at
the conclusion of such enforcement action it is determined that the amounts
described in clauses first and second are insufficient, then pursuant to Section
3.05(a)(viii) out of general collections on the Loans on deposit in the
Collection Account.

            Section 2.04      Execution of Certificates.

            Subject to Sections 2.01 and 2.02, the Trustee hereby acknowledges
the assignment to it of the Loans and the delivery to the Custodian on its
behalf of the Mortgage Files and fully executed original counterparts of the
Mortgage Loan Purchase Agreements, together with the assignment to it of all
other assets included in the Trust Fund. Concurrently with such assignment and

                               ADMINISTRATION AND
                           SERVICING OF THE TRUST FUND

            Section 3.01      Servicer  to  Act  as   Servicer;   Special
Servicer to Act as Special Servicer; Administration of the Loans.

            (a) Each of the Servicer and the Special Servicer shall diligently
service and administer the Loans (and, with respect to the Special Servicer, any
REO Properties) it is obligated to service pursuant to this Agreement, subject
to the servicing of the L'Enfant Participation by the L'Enfant Servicer and
L'Enfant Special Servicer, on behalf of the Trust Fund and in the best interests
of and for the benefit of the Certificateholders as well (as determined by the
Servicer or the Special Servicer, as the case may be, in its good faith and
reasonable judgment) in accordance with applicable law, the terms of the
respective Loans or Specially Serviced Loans, and, to the extent consistent with
the foregoing, the terms of this Agreement, in the case of the L'Enfant
Participation and the Exchange Apartments Loan, the related Co-Lender Agreement,
in the case of the L'Enfant Participation, the L'Enfant Participation Agreement,
and, to the extent consistent with the foregoing, in accordance with the higher
of the following standards of care: (1) the same manner in which, and with the
same care, skill, prudence and diligence with which, the Servicer or Special
Servicer, as the case may be, services and administers similar commercial or
multifamily mortgage loans for other third-party portfolios, giving due
consideration to the customary and usual standards of practice of prudent
institutional multifamily or commercial mortgage lenders servicing their own
mortgage loans and (2) the same care, skill, prudence and diligence with which
the Servicer or Special Servicer, as the case may be, services and administers
similar commercial or multifamily mortgage loans owned by the Servicer or
Special Servicer, in either case exercising reasonable business judgment and
with a view to the maximization, on a present value basis (discounting at the
related Mortgage Rate), of timely recovery of principal and interest on the
Loans or Specially Serviced Loans, as applicable, but without regard to: (i) any
relationship that the Servicer or the Special Servicer, as the case may be, or
any Affiliate thereof may have with the related Mortgagor or any other party to
this Agreement; (ii) the ownership of any Certificate by the Servicer or the
Special Servicer, as the case may be, or any Affiliate thereof; (iii) the
Servicer's obligation to make Advances; (iv) the Servicer's or Special
Servicer's, as the case may be, right to receive compensation for its services
hereunder or with respect to any particular transaction; and (v) the Servicer's
or Special Servicer's ownership, servicing or management of any other mortgage
loans or mortgaged properties (the foregoing, collectively referred to as the
"Servicing Standard"). Nothing herein contained shall be construed as an express
or implied guarantee by the Servicer or the Special Servicer of the
collectibility of payments on the Loans or shall be construed as impairing or
adversely affecting any rights or benefits specifically provided by this
Agreement to the Servicer or the Special Servicer, including with respect to
Servicing Fees or Special Servicing Fees or, with respect to the Servicer, the
right to be reimbursed for Advances.

            Without limiting the foregoing, subject to Section 3.21, the Special
Servicer shall be obligated to service and administer (i) any Loans as to which
a Servicing Transfer Event has occurred and is continuing (each such Loan, a
"Specially Serviced Loan"), and (ii) any REO Properties. Notwithstanding the
foregoing, the Servicer shall continue to make all calculations, and prepare, or
cause to be prepared by the Special Servicer and delivered to the Trustee and
the Certificate Administrator, all reports to the Trustee and the Certificate
Administrator required hereunder with respect to the Specially Serviced Loans 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
Loan and REO Properties as are specifically provided for herein; provided,
however, that the Servicer shall not be liable for failure to comply with such
duties insofar as such failure results from a failure of the Special Servicer to
provide sufficient information to the Servicer to comply with such duties or a
failure of the Special Servicer to prepare and deliver to the Servicer reports
required hereunder to be delivered by the Special Servicer to the Servicer. Each
Loan that becomes a Specially Serviced Loan shall continue as such until
satisfaction of the conditions specified in Section 3.21(a). Without limiting
the foregoing, subject to Section 3.21, the Servicer shall be obligated to
service and administer all Loans which are not Specially Serviced Loans;
provided, however, that the Special Servicer shall make the inspections, use its
reasonable best efforts to collect the statements and shall prepare the reports
in respect of the related Mortgaged Properties with respect to Specially
Serviced Loans in accordance with Section 3.12.

            (b) Subject only to the Servicing Standard and the terms of this
Agreement and of the respective Loans, the 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 Servicer and the Special Servicer, in its own name, is
hereby authorized and empowered by the Trustee and obligated to execute and
deliver, on behalf of the Certificateholders and the Trustee or any of them,
with respect to each Loan it is obligated to service under this Agreement, any
and all financing statements, continuation statements and other documents or
instruments necessary to maintain the lien created by the related Mortgage or
other security document in the related Mortgage File on the related Mortgaged
Property and related collateral; subject to Section 3.20, any and all
modifications, waivers, amendments or consents to or with respect to any
documents contained in the related Mortgage File; and any and all instruments of
satisfaction or cancellation, or of partial or full release or discharge, and
all other comparable instruments. Subject to Section 3.10, the Trustee shall
furnish, or cause to be furnished, to the Servicer or the Special Servicer any
limited powers of attorney and other documents necessary or appropriate to
enable the Servicer or the Special Servicer, as the case may be, to carry out
its servicing and administrative duties hereunder; provided, however, that the
Trustee shall not be held liable for any negligence with respect to, or misuse
of, any such power of attorney by the Servicer or the Special Servicer.

            (c) The relationship of each of the 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 venturer, partner or
agent.

            Section 3.02      Collection of Loan Payments.

            (a) Each of the Servicer and the Special Servicer shall make
reasonable efforts to collect all payments called for under the terms and
provisions of the Loans it is obligated to service hereunder, and shall follow
such collection procedures as are consistent with this Agreement (including,
without limitation, the Servicing Standard). Consistent with the foregoing, the
Servicer or the Special Servicer each may in its discretion waive any Penalty
Charge in connection with any delinquent payment on a Loan it is obligated to
service hereunder.

            (b) All amounts collected on any Loan in the form of payments from
Mortgagors, Insurance and Condemnation Proceeds or Liquidation Proceeds shall be
applied to amounts due and owing under the related Note and Mortgage (including
any modifications to either of them) in accordance with the express provisions
of such Note and Mortgage (unless a payment default exists under such Loan and
the related Note and Mortgage permit application in the order and priority
determined by the lender) and, in the absence of such express provisions, shall
be applied (after payment to the Servicer, any Primary Servicer, the Special
Servicer, the Certificate Administrator and/or the Trustee for any related
Servicing Fees, Primary Servicing Fees, Special Servicing Fees, the Certificate
Administrator Fees and Trustee Fees and the application to any P&I Advances,
Servicing Advances and interest on Advances from such Loan): first, as a
recovery of accrued and unpaid interest on such Loan at the related Mortgage
Rate (less portions thereof payable to the Servicer, Special Servicer, the
Certificate Administrator, Trustee or, if applicable, the related Primary
Servicer) in effect from time to time to but not including the Due Date in the
Due Period of receipt; second, as a recovery of principal of such Loan; and
third, to the payment of Prepayment Premiums and Yield Maintenance Charges.
Notwithstanding the terms of any Loan, the Servicer shall not be entitled to the
payment of any Penalty Charge in excess of outstanding interest on Advances made
with respect to such Loan, except to the extent that (i) all reserves then
required to be funded pursuant to the terms of such Loan have been so funded,
(ii) all payments of principal and interest then due on such Loan have been paid
and (iii) all related operating expenses, if applicable, have been paid to the
related Lock-Box or reserved for pursuant to the related Lock-Box Agreement. In
no event shall any collections on any ARD Loan be allocated to the payment of
Excess Interest until all principal and interest (other than Excess Interest)
due, or to become due, under such ARD Loan have been paid in full. Amounts
collected on any REO Loan shall be deemed to be applied in accordance with the
definition thereof.

            (c) If the Servicer or Special Servicer receives, or receives notice
from the related Borrower that it will be receiving, Excess Interest in any Due
Period, the Servicer or Special Servicer, as applicable, shall promptly notify
the Certificate Administrator in writing.

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

            (a) The Servicer shall establish and maintain one or more accounts
(the "Servicing Accounts"), into which all Escrow Payments shall be deposited
and retained, and shall administer such Servicing Accounts in accordance with
the related Loan Documents. Each Servicing Account shall be maintained in
accordance with the requirements of the related Loan and in accordance with the
Servicing Standard and to the extent not inconsistent with the terms of the
Loans, in an Eligible Account. Funds on deposit in the Servicing Accounts may be
invested in Permitted Investments in accordance with the provisions of Section
3.06. Withdrawals of amounts so deposited from a Servicing Account may be made
only to: (i) effect payment of real estate taxes, assessments, Insurance Policy
premiums, ground rents (if applicable) and other items for which funds have been
escrowed in the Servicing Accounts; (ii) reimburse the Servicer or the Trustee
for any Servicing Advances; (iii) refund to Mortgagors any sums as may be
determined to be overages; (iv) pay interest to Mortgagors on balances in the
Servicing Account, if required by applicable law or the terms of the related
Loan and as described below or, if not so required, to the Servicer; (v)
withdraw amounts deposited in error; (vi) clear and terminate the Servicing
Accounts at the termination of this Agreement in accordance with Section 9.01;
and (vii) pay the Servicer, as additional servicing compensation in accordance
with Section 3.11(a), interest and investment income earned in respect of
amounts relating to the Trust Fund held in the Servicing Accounts as provided in
Section 3.06(b) (but only to the extent of the Net Investment Earnings with
respect to the Servicing Accounts for any period from any Distribution Date to
the immediately succeeding P&I Advance Date) to the extent not required by law
or the terms of the related Loan to be paid to the Mortgagors.

            (b) The Special Servicer, in the case of REO Loans and Specially
Serviced Loans, and the Servicer, in the case of all other Loans, shall maintain
accurate records with respect to each related Mortgaged Property reflecting the
status of real estate taxes, assessments and other similar items that are or may
become a lien thereon (including related penalty or interest charges) and the
status of Insurance Policy premiums and any ground rents payable in respect
thereof. The Special Servicer, in the case of REO Loans and Specially Serviced
Loans, and the Servicer, in the case of all other Loans, shall obtain all bills
for the payment of such items (including renewal premiums) and shall effect
payment thereof from the REO Account or the Servicing Accounts, and, if such
amounts are insufficient to pay such items in full, the Servicer shall make a
Servicing Advance prior to the applicable penalty or termination date, as
allowed under the terms of the related Loan and, in any event, consistent with
the Servicing Standard. Notwithstanding anything to the contrary in the
preceding sentence, with respect to Loans that do not provide for escrows for
the payment of taxes and assessments, the Servicer shall make a Servicing
Advance for the payment of such items upon the earlier of (x) 30 days after the
date such payments first become delinquent and (y) five Business Days before the
scheduled date of foreclosure of any lien arising from nonpayment of such items
(which Servicing Advance shall in each case be so applied by the Servicer at the
written direction of the Special Servicer in the case of Specially Serviced
Loans and REO Loans). In no event shall the Servicer or the Special Servicer be
required to make any such Servicing Advance that would, if made, be a
Nonrecoverable Servicing Advance. To the extent that a Loan does not require a
Mortgagor to escrow for the payment of real estate taxes, assessments, Insurance
Policy premiums, ground rents (if applicable) and similar items, the Special
Servicer, in the case of Specially Serviced Loans and REO Loans, and the
Servicer, in the case of all other Loans, shall use reasonable efforts
consistent with the Servicing Standard to require that payments in respect of
such items be made by the Mortgagor at the time they first become due.

            (c) In accordance with the Servicing Standard and for all Loans, the
Servicer shall make a Servicing Advance with respect to each related Mortgaged
Property (including any REO Property) of all such funds as are necessary for the
purpose of effecting the payment of (i) ground rents (if applicable), (ii)
premiums on Insurance Policies, (iii) operating, leasing, managing and
liquidation expenses for REO Properties and (iv) environmental inspections and
remediations, if any, in each instance if and to the extent monies in the
Servicing Accounts 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
Servicer shall not be required to make any such advance that would, if made,
constitute a Nonrecoverable Servicing Advance; and provided further that with
respect to the payment of taxes and assessments, the Servicer shall not be
required to make any such advance until the earlier of (i) five Business Days
after the Servicer has received confirmation that such item has not been paid
and (ii) with respect to Loans that provide for escrows for the payment of taxes
and assessments, the earlier of (A) 30 days after the date such payments first
become due and (B) five Business Days before the scheduled date of foreclosure
of any lien arising from nonpayment of such items.

            The Special Servicer shall give the Servicer, the Certificate
Administrator and the Trustee not less than five Business Days' notice before
the date on which the Servicer is required to make any Servicing Advance with
respect to a given 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 Servicer and the Trustee with
such information in its possession as the Servicer or the Trustee, as
applicable, may reasonably request to enable the Servicer or the Trustee, as
applicable, to determine whether a requested Servicing Advance would constitute
a Nonrecoverable Servicing Advance. Any request by the Special Servicer that the
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 Servicer shall be entitled to conclusively rely on
such determination, provided that such determination shall not be binding upon
the Servicer. On the fourth Business Day before each Distribution Date, the
Special Servicer shall report to the Servicer the Special Servicer's
determination as to whether any Servicing Advance previously made with respect
to a Specially Serviced Loan or REO Loan is a Nonrecoverable Servicing Advance.
The Servicer shall be entitled to conclusively rely on such a determination,
provided that such determination shall not be binding upon the Servicer.

            All such Servicing Advances shall be reimbursable in the first
instance from related collections from the Mortgagors and further as provided in
Section 3.05. No costs incurred by the Servicer or the Special Servicer in
effecting the payment of real estate taxes, assessments and, if applicable,
ground rents on or in respect of the Mortgaged Properties shall, for purposes
hereof, including, without limitation, calculating monthly distributions to
Certificateholders, be added to the unpaid principal balances of the related
Loans, notwithstanding that the terms of such Loans so permit. If the Servicer
fails to make any required Servicing Advance as and when due to the extent a
Responsible Officer of the Trustee has been notified of such failure in writing
by the Servicer, Special Servicer or Depositor, the Trustee shall make such
Servicing Advance pursuant to Section 7.05.

            (d) In connection with its recovery of any Servicing Advance out of
the Collection Account pursuant to clauses (iv) or (v) of Section 3.05(a) or
from a Servicing Account pursuant to Section 3.03(a)(ii), each of the Servicer
and the Trustee, as the case may be, shall be entitled to receive, out of any
amounts then on deposit in the Collection Account, interest at the Reimbursement
Rate in effect from time to time, accrued on the amount of such Servicing
Advance from and including the date made to, but not including, the date of
reimbursement. The Servicer shall reimburse itself or the Trustee, as the case
may be, for any outstanding Servicing Advance as soon as practically possible
after funds available for such purpose are deposited in the Collection Account.

            (e) To the extent an operations and maintenance plan is required to
be established and executed pursuant to the terms of a Loan, the Servicer or,
with respect to Specially Serviced Loans, the Special Servicer shall request
from the Mortgagor written confirmation thereof within a reasonable time after
the later of the Closing Date and the date as of which such plan is required to
be established or completed. To the extent any repairs, capital improvements,
actions or remediations are required to have been taken or completed pursuant to
the terms of the Loan, the Servicer or, with respect to Specially Serviced
Loans, the Special Servicer shall request from the Mortgagor written
confirmation of such actions and remediations within a reasonable time after the
later of the Closing Date and the date as of which such action or remediations
are required to be or to have been taken or completed. To the extent a Mortgagor
fails to promptly respond to any inquiry described in this Section 3.03(e), the
Servicer (with respect to Loans that are not Specially Serviced Loans) shall
determine whether the related Mortgagor has failed to perform its obligations
under the related Loan and report any such failure to the Special Servicer
within a reasonable time after the date as of which such operations and
maintenance plan is required to be established or executed or the date as of
which such actions or remediations are required to be or to have been taken or
completed.

            Section 3.04      The   Collection   Account,   Distribution
Accounts,  Excess  Interest  Distribution  Account  and Yield  Protection
Payment Account.

            (a) The Servicer shall establish and maintain, or cause to be
established and maintained, the Collection Account, into which the Servicer
shall deposit or cause to be deposited on a daily basis (and in no event later
than the Business Day following receipt of available funds), except as otherwise
specifically provided herein, the following payments and collections received
after the Cut-off Date (other than payments of principal and interest on the
Loans due and payable on or before the Cut-off Date) and 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,   including
      Principal Prepayments, on the Loans; and

               (ii) all payments on account of interest on the Loans, net of (A)
      the Servicing Fees and Primary Servicing Fees (in each case net of any
      amount utilized to offset Prepayment Interest Shortfalls), (B) Penalty
      Charges (net of any amount thereof utilized to offset interest on
      Advances), (C) Prepayment Premiums, (D) Excess Interest and (E) Yield
      Maintenance Charges; and

               (iii) all Insurance and Condemnation Proceeds and Liquidation
      Proceeds received in respect of any Loan or REO Property (other than
      Liquidation Proceeds that are to be deposited in the Lower-Tier
      Distribution Account pursuant to Section 9.01); and

               (iv) any amounts required to be transferred from the REO Account
      pursuant to Section 3.16(c); and

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

               (vi) any amounts required to be deposited by the 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; and

               (vii) any amounts required to be deposited by the Servicer
      pursuant to the last paragraph of Section 3.11(a) as a reduction in the
      compensation to the Servicer to cover Prepayment Interest Shortfalls; and

               (viii) any Prepayment Interest Excess to which the Servicer is
      not entitled as provided in Section 3.11(a).

            The foregoing requirements for deposit in the Collection Account
shall be exclusive, it being understood and agreed that actual payments from
Mortgagors in the nature of Escrow Payments, charges for beneficiary statements
or demands, assumption fees, modification fees, extension fees, amounts
collected for mortgagor checks returned for insufficient funds or other amounts
that the Servicer or Special Servicer is entitled to retain as additional
servicing compensation pursuant to Section 3.11 need not be deposited by the
Servicer in the Collection Account. If the Servicer shall deposit in the
Collection Account any amount not required to be deposited therein, it may at
any time withdraw such amount from the Collection Account.

            Within one Business Day of receipt of any of the foregoing amounts
with respect to any Specially Serviced Loan, the Special Servicer shall remit
such amounts to the Servicer for deposit into the Collection Account in
accordance with the second preceding paragraph. Any amounts received by the
Special Servicer with respect to an REO Property shall be deposited into the REO
Account and remitted to the Servicer for deposit into the Collection Account
pursuant to Section 3.16(c).

            (b) The Certificate Administrator shall establish and maintain the
Distribution Accounts in trust for the benefit of the Certificateholders. The
Certificate Administrator shall make or be deemed to have made deposits in and
withdrawals from the Distribution Accounts in accordance with the terms of this
Agreement. The Servicer shall deliver to the Certificate Administrator each
month on or before 3:00 p.m., New York City time, on the Servicer Remittance
Date, for deposit in the Lower-Tier Distribution Account, that portion of the
Available Distribution Amount (calculated without regard to clauses (a)(v) and
(c) of the definition thereof) for the related Distribution Date then on deposit
in the Collection Account.

            The Servicer shall, as and when required hereunder, deliver to the
Certificate Administrator for deposit in the Lower-Tier Distribution Account:

               (i) any P&I Advances required to be made by the Servicer in
      accordance with Section 4.03 (or, if the Trustee succeeds to the
      Servicer's obligations hereunder, Section 7.05);

               (ii) any Liquidation Proceeds paid by the Servicer in connection
      with the purchase of all of the Loans and any REO Properties in the Trust
      Fund pursuant to Section 9.01 (exclusive of that portion thereof required
      to be deposited in the Collection Account pursuant to Section 9.01);

               (iii) any Yield Maintenance Charges  or Prepayment Premiums; and

               (iv) any other amounts required to be so delivered for deposit in
      the Lower-Tier Distribution Account pursuant to any provision of this
      Agreement.

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

            On each Distribution Date, the Certificate Administrator shall
deposit or be deemed to have deposited in the Upper-Tier Distribution Account an
aggregate amount of immediately available funds equal to the Lower-Tier
Distribution Amount and the amount of any Prepayment Premiums and Yield
Maintenance Charges for such Distribution Date allocated in payment of the
Uncertificated Lower-Tier Interests as specified in Sections 4.01(b) and
4.01(e), respectively.

            (c) Prior to the Servicer Remittance Date relating to any Due Period
in which Excess Interest is received, the Certificate Administrator shall
establish and maintain the Excess Interest Distribution Account in the name of
the Certificate Administrator for the benefit of the Trustee, for the benefit of
the Holders of the Class V-1 and Class V-2 Certificates. The Excess Interest
Distribution Account shall be established and maintained as an Eligible Account.
On or before each Servicer Remittance Date, the Servicer shall remit to the
Certificate Administrator for deposit in the Excess Interest Distribution
Account an amount equal to the Excess Interest received during the related Due
Period. On each Distribution Date, the Certificate Administrator shall withdraw
the Excess Interest from the Excess Interest Distribution Account for
distribution pursuant to Section 4.01(f). Following the distribution of Excess
Interest to Holders of the Class V-1 and Class V-2 Certificates on the first
Distribution Date after which no Loans remain outstanding that pursuant to their
terms could pay Excess Interest, the Certificate Administrator shall terminate
the Excess Interest Distribution Account.

            (d) Prior to the Servicer Remittance Date relating to any Due Period
in which an Additional Collateral Prepayment Amount is prepaid, the Certificate
Administrator shall establish and maintain the Yield Protection Payment Account
in the name of the Certificate Administrator for the benefit of the Trustee, for
the benefit of the Holders of the Regular Certificates. The Yield Protection
Payment Account shall be established and maintained as an Eligible Account. On
or before each Servicer Remittance Date, as required by Section 4.03(g), the
Servicer shall remit to the Certificate Administrator for deposit in the Yield
Protection Payment Account the Yield Protection Payment Advance, if any, for the
related Distribution Date. On each Distribution Date, the Certificate
Administrator shall withdraw the Yield Protection Payment from the Yield
Protection Payment Account for distribution pursuant to Section 4.01(k).
Following the distribution of the Class A-X Yield Protection Payment Amount to
Holders of the Class A-X Certificates and the distribution of the Regular Yield
Protection Payment Amount to Holders of the applicable Class of Regular
Certificates, in each case on the first Distribution Date after which all
Additional Collateral has been released to the Borrowers under the Additional
Collateral Loans or collected by the Servicer as Principal Prepayments, the
Certificate Administrator shall terminate the Yield Protection Payment Account.

            (e) Funds on deposit in the Collection Account may be invested only
in Permitted Investments in accordance with the provisions of Section 3.06.
Funds on deposit in the Upper-Tier Distribution Account and the Lower-Tier
Distribution Account shall not be invested. As of the Closing Date, the
Collection Account shall be located at the offices of the Servicer and
Sub-Servicers. The Servicer shall give notice to the Trustee, the Certificate
Administrator, the Special Servicer, the Rating Agencies and the Depositor of
any new location of the Collection Account prior to any change thereof. As of
the Closing Date (or the date such account is established, if later), the
Upper-Tier Distribution Account, the Lower-Tier Distribution Account, the Excess
Interest Distribution Account and the Yield Protection Payment Account shall be
located at the offices of the Certificate Administrator. The Certificate
Administrator shall give notice to the Servicer and the Depositor of any new
location of the Upper-Tier Distribution Account, the Lower-Tier Distribution
Account, the Excess Interest Distribution Account or the Yield Protection
Payment Account, prior to any change thereof.

            Section 3.05      Permitted  Withdrawals  from the  Collection
Account and the Distribution Accounts.

            (a) The Servicer may, from time to time, make withdrawals from the
Collection Account for any of the following purposes:

               (i) to remit to the Certificate Administrator for deposit in the
      Lower-Tier Distribution Account the amount required to be remitted
      pursuant to the first paragraph of Section 3.04(b) and the amount to be
      applied to make P&I Advances pursuant to Section 4.03(a);

               (ii) to pay (x) to itself, unpaid Servicing Fees (net of any such
      amounts required to offset Prepayment Interest Shortfalls pursuant to
      Section 3.11(a)) and any Primary Servicing Fees to which it is entitled
      pursuant to Section 3.11(a), (y) to any Primary Servicer entitled thereto,
      the related Primary Servicing Fee, and (z) to the Special Servicer, unpaid
      Special Servicing Fees, Liquidation Fees and Workout Fees in respect of
      each Loan, Specially Serviced Loan and REO Loan, as applicable, the
      Servicer's rights, any Primary Servicer's rights and the Special
      Servicer's rights to payment pursuant to this clause (ii) with respect to
      any Loan or REO Loan, as applicable, being limited to amounts received on

               (viii) in accordance with Section 2.03(e), to reimburse itself,
      the Trustee or the Special Servicer, as the case may be, out of general

      the third paragraph of Section 3.11(a); and to pay the Special Servicer,
      as additional servicing compensation in accordance with the last paragraph
      of Section 3.11(b), Penalty Charges on any Specially Serviced Loan (but
      only to the extent collected from the related Mortgagor and to the extent

      all amounts received thereon subsequent to the date of purchase;

               (xvi) to reimburse the Special Servicer for the cost of any
      environmental testing performed at the Special Servicer's direction
      pursuant to the last sentence of Section 3.09(c); and

               (xvii) to clear and terminate the Collection Account at the

            The Servicer shall keep and maintain separate accounting records, on

      Upper-Tier Distribution Account;

               (ii)   to   pay   the   Trustee   and   the    Certificate

      hereunder, including pursuant to Section 3.31(o), 6.03(a), 6.03(b),
      8.05(c), 8.05(d) or 8.05(e);

               (iv) to pay for the cost of the Opinion of Counsel contemplated
      by Section 10.01(c) in connection with any amendment to this Agreement

      Distribution Account in error.

            (c) The Certificate Administrator may make withdrawals from the
Upper-Tier Distribution Account for any of the following purposes:

               (i) to make distributions to Certificateholders (other than
      Holders of the Class LR Certificates) on each Distribution Date pursuant
      to Section 4.01 or 9.01, as applicable;

               (ii)  to   clear    and    terminate    the    Upper-Tier
      Distribution  Account at the  termination of this Agreement  pursuant
      to Section 9.01; and

               (iii) to recoup any amounts deposited in the Upper-Tier
      Distribution Account in error.

            (d) Notwithstanding anything herein to the contrary, with respect to
any Loan, (i) if amounts on deposit in the Collection Account and the Lower-Tier
Distribution Account are not sufficient to pay the full amount of the Servicing
Fee listed in Section 3.05(a)(ii) and the Trustee Fee and Certificate
Administrator Fee listed in Section 3.05(b)(ii), then the Trustee Fee and
Certificate Administrator Fee shall be paid in full prior to the payment of any
Servicing Fees payable under Section 3.05(a)(ii) and (ii) if amounts on deposit
in the Collection Account are not sufficient to reimburse the full amount of
Advances listed in Sections 3.05(a)(iii), (iv), (v) and (vi), then
reimbursements shall be paid first to the Trustee and then to the Servicer.

            (e) Notwithstanding anything herein to the contrary, under no
circumstances shall (i) funds in any account other than the Yield Protection
Payment Account be applied to Yield Protection Payments or (ii) a Yield
Protection Payment Advance be deemed to be an Advance reimbursable pursuant to
Section 3.05(a).

            Section 3.06 Investment of Funds in the Collection Account,
Servicing Accounts, Cash Collateral Accounts, Lock-Box Accounts, Policy Escrow
Accounts, the Interest Reserve Account and the REO Account.

            (a) The Servicer may direct any depository institution maintaining
the Collection Account, any Servicing Account, any Cash Collateral Account, any
Lock-Box Account, any Policy Escrow Account and the Interest Reserve Account,
and the Special Servicer may direct any depository institution maintaining the
REO Account (any of the foregoing accounts, for purposes of this Section 3.06,
an "Investment Account"), to invest (or if such depository institution is the
Servicer or the Special Servicer, as applicable, it may itself invest) the funds
held therein solely in one or more Permitted Investments bearing interest or
sold at a discount, and maturing, unless payable on demand, (i) 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,
if a Person other than the depository institution maintaining such account is
the obligor thereon and (ii) no later than the date on which such funds are
required to be withdrawn from such account pursuant to this Agreement, if the
depository institution maintaining such account is the obligor thereon. 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). Funds on deposit in the Excess Interest
Distribution Account, Yield Protection Payment Account and Distribution Accounts
shall remain uninvested.

            The Servicer (in the case of any Investment Account other than the
REO Account) or the Special Servicer (in the case of the REO Account), on behalf
of the Trustee, shall maintain continuous possession of any Permitted Investment
of amounts in such accounts 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 Servicer or
the Special Servicer shall constitute possession by the Trustee, as secured
party, for purposes of Section 9-305 of the UCC and any other applicable law. In
the event amounts on deposit in an Investment Account are at any time invested
in a Permitted Investment payable on demand, the Servicer (in the case of any
Investment Account other than the REO Account) or the Special Servicer (in the
case of the REO Account) shall:

               (i)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 (a) all amounts then payable thereunder and (b) the amount required to
      be withdrawn on such date; and

               (ii) demand payment of all amounts due thereunder promptly upon
      determination by the Servicer or the Special Servicer, 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) Interest and investment income realized on funds deposited in
each of the Collection Account, the Interest Reserve Account, any Cash
Collateral Account, any Lock-Box Account and any Servicing Account, to the
extent of the Net Investment Earnings, if any, with respect to such account for
each period from any Distribution Date to the immediately succeeding P&I Advance
Date shall be for the sole and exclusive benefit of the Servicer to the extent
not required to be paid to the related Borrower and shall be subject to its
withdrawal, or withdrawal at its direction, in accordance with Section 3.03(a),
3.05(a), 3.05(b) or 3.05(c), as the case may be. Interest and investment income
realized on funds deposited in any Policy Escrow Account shall be used to pay
any interest on Advances made with respect to, or any other expenses of the
Trust Fund allocable to, the related Loan, and the Servicer shall not be
entitled to any such interest or investment income. Interest and investment
income realized on funds deposited in the REO Account, to the extent of the Net
Investment Earnings, if any, with respect to such account for each period from
any Distribution Date to the immediately succeeding P&I Advance Date, shall be
for the sole and exclusive benefit of the Trust Fund and shall be subject to its
withdrawal in accordance with Section 3.16(c). If any loss shall be incurred in
respect of any Permitted Investment on deposit in any of the Collection Account,
any Cash Collateral Account, any Lock-Box Account, any Servicing Account or the
REO Account, the Servicer (in the case of the Collection Account, any Cash
Collateral Account, any Lock-Box Account and any Servicing Account) or the
Special Servicer (in the case of the REO Account) shall deposit therein, no
later than the P&I Advance Date, without right of reimbursement, the amount of
the Net Investment Loss, if any, with respect to such account for the period
from the immediately preceding Distribution Date to such P&I Advance Date. The
Servicer shall not be liable for any loss incurred in respect of any Permitted
Investments on deposit in the Policy Escrow Account, provided the Servicer shall
comply with the requirements of Section 3.06(a).

            (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, the Trustee may and, subject to Section 8.02, upon the request of
Holders of Certificates entitled to a majority 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.

            Notwithstanding the investment of funds held in the Collection
Account pursuant to this Section 3.06, for purposes of calculating the Available
Distribution Amount, the amounts so invested shall be deemed to remain on
deposit in such account.

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

            (a) The Servicer as to Loans that are not Specially Serviced Loans
and the Special Servicer as to Specially Serviced Loans shall use their
respective reasonable best efforts to cause the Mortgagor to maintain, to the
extent required by the terms of the related Note and Mortgage, or if the
Mortgagor does not so maintain, shall itself maintain, for each Loan any
Insurance Policy coverage as is required under the related Mortgage (to the
extent that the Trustee has an insurable interest and such Insurance Policy
coverage is available at commercially reasonable rates, as determined by the
Servicer or the Special Servicer, as applicable, in accordance with the
Servicing Standard); provided, however, that, subject to Section 3.07(f), if any
Mortgage permits the holder thereof to dictate to the Mortgagor the Insurance
Policy coverage to be maintained on such Mortgaged Property, the Servicer or the
Special Servicer, as applicable, shall impose such insurance requirements as are
consistent with the Servicing Standard. Subject to Section 3.17(a), the Special
Servicer shall maintain for each REO Property no less Insurance Policy coverage
than was previously required of the Mortgagor under the related Loan.

            All such Insurance Policies shall (i) contain a "standard" mortgagee
clause, with loss payable to the Servicer on behalf of the Trustee (in the case
of insurance maintained in respect of Loans other than REO Properties) or the
Special Servicer on behalf of the Trustee (in the case of insurance maintained
in respect of REO Properties), (ii) include coverage in an amount not less than
the lesser of the full replacement cost of the improvements which are a part of
the Mortgaged Property or the outstanding principal balance owing on the related
Loan, but in any case in such an amount so as to avoid the application of any
co-insurance clause, (iii) include a replacement cost endorsement providing no
deduction for depreciation (unless such endorsement is not permitted under the
related Loan Documents) and (iv) be issued by either (x) a Qualified Insurer or
(y) for any Insurance Policy being maintained by the related Mortgagor, an
insurance carrier meeting the requirements of the related Mortgage, provided
that such Qualified Insurer or other insurance carrier is authorized under
applicable law to issue such Insurance Policies. Any amounts collected by the
Servicer or the Special Servicer under any such Insurance 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 in accordance with the Servicing Standard and the provisions of the
related Loan) shall be deposited in the Collection Account, subject to
withdrawal pursuant to Section 3.05(a).

            Any costs incurred by the Servicer in maintaining any such Insurance
Policies in respect of Loans (other than with respect to REO Properties) if the
Mortgagor defaults on its obligation to maintain such Insurance Policies shall
be advanced by the Servicer as a Servicing Advance. The amounts so advanced
shall not, for purposes of calculating monthly distributions to
Certificateholders, be added to the unpaid principal balance of the related
Loan, notwithstanding that the terms of such Loan so permit. Any cost incurred
by the Special Servicer in maintaining any such Insurance Policies with respect
to REO Properties shall be an expense of the Trust Fund payable out of the
related REO Account pursuant to Section 3.16(c) or, if the amount on deposit
therein is insufficient therefor, advanced by the Servicer as a Servicing
Advance.

            (b) (i) If the Servicer or the Special Servicer obtains and
maintains a blanket Insurance Policy with a Qualified Insurer insuring against
fire and hazard losses on all of the Loans or REO Properties, as the case may
be, required to be serviced and administered by it hereunder, and such Insurance
Policy provides protection equivalent to the individual policies otherwise
required, then the Servicer or the Special Servicer, as the case may be, shall
conclusively be deemed to have satisfied its obligation to cause fire and hazard
insurance to be maintained on the related Mortgaged Properties or REO
Properties. Such blanket Insurance Policy may contain a deductible clause, in
which case if there shall not have been maintained on the related Mortgaged
Property or REO Property a fire and hazard Insurance Policy complying with the
requirements of Section 3.07(a), and there shall have been one or more losses
which would have been covered by such Insurance Policy, the Servicer or the
Special Servicer shall promptly deposit into the Collection Account from its own
funds the portion of such loss or losses that would have been covered under the
individual policy (giving effect to any deductible limitation or, in the absence
of such deductible limitation, the deductible limitation that is consistent with
the Servicing Standard) but is not covered under the blanket Insurance Policy
because of such deductible clause. In connection with its activities as
administrator and servicer of the Loans, the Servicer agrees to prepare and
present, on behalf of itself, the Trustee and Certificateholders, claims under
any such blanket Insurance Policy in a timely fashion in accordance with the
terms of such policy. The Special Servicer, to the extent consistent with the
Servicing Standard, may maintain earthquake insurance on REO Properties,
provided coverage is available at commercially reasonable rates.

               (ii) If the Servicer or the Special Servicer causes any Mortgaged
Property or REO Property to be covered by a master single interest Insurance
Policy with a Qualified Insurer naming the Servicer or the Special Servicer as
the loss payee, then to the extent such Insurance Policy provides protection
equivalent to the individual policies otherwise required, the Servicer or the
Special Servicer shall conclusively be deemed to have satisfied its obligation
to cause such insurance to be maintained on the related Mortgage Properties and
REO Properties. If the Servicer or the Special Servicer causes any Mortgaged
Property or REO Property to be covered by such master single interest Insurance
Policy, the incremental costs of such insurance applicable to such Mortgaged
Property or REO Property (i.e., other than any minimum or standby premium
payable for such policy whether or not any Mortgaged Property or REO Property is
covered thereby) shall be paid by the Servicer out of its own funds. Such master
single interest Insurance Policy may contain a deductible clause, in which case
the Servicer or the Special Servicer shall, if (A) there shall not have been
maintained on the related Mortgaged Property or REO Property a policy otherwise
complying with the provisions of Section 3.07(a) and (B) there shall have been
one or more losses which would have been covered by such policy had it been
maintained, deposit into the Collection Account from its own funds the amount
not otherwise payable under the master single interest Insurance Policy because
of such deductible clause, to the extent that any such deductible exceeds the
deductible limitation that pertained to the related Loan, or, in the absence of
any such deductible limitation, the deductible limitation which is consistent
with the Servicing Standard.

            (c) Each of the Servicer and Special Servicer shall maintain with
responsible companies, at their own expense, a blanket fidelity bond (a
"Fidelity Bond") and an errors and omissions insurance policy with a Qualified
Insurer, with broad coverage on all officers, employees or other personnel
acting in any capacity requiring such persons to handle funds, money, documents
or paper relating to the Loans ("Servicer Employees," in the case of the
Servicer, and "Special Servicer Employees," in the case of the Special
Servicer). Any such Fidelity Bond and errors and omissions insurance shall
protect and insure the Servicer against losses, including forgery, theft,
embezzlement, fraud, errors and omissions, failure to maintain any insurance
policies required pursuant to the Agreement and negligent acts of such Servicer
Employees or Special Servicer Employees. Such errors and omissions policy shall
also protect and insure the Servicer against losses in connection with the
release or satisfaction of a Loan without having obtained payment in full of the
indebtedness secured thereby. No provision of this Section requiring such
Fidelity Bond and errors and omissions insurance shall diminish or relieve the
Servicer or Special Servicer from its duties and obligations as set forth in
this Agreement.

            The minimum coverage under any such Fidelity Bond and errors and
omissions insurance policy shall be at least equal to the greater of (i) the
amount necessary for the Servicer or Special Servicer, as applicable, to qualify
as a FNMA or FHLMC servicer or in an amount that would meet the requirements of
prudent institutional commercial mortgage loan servicers for similar
transactions, and (ii) $1,000,000. The Servicer or the Special Servicer, as
applicable, shall cause the Trustee, on behalf of the Trust, to be named as a
loss payee on each such Fidelity Bond and errors and omissions policy.
Notwithstanding the foregoing, so long as the long-term debt or the deposit
obligations or claims-paying ability of the Servicer or Special Servicer (or its
immediate or remote parent) is rated at least "A" by DCR, "A2" by Moody's and
"A" by Fitch (or, if not rated by Fitch, upon written confirmation by Fitch that
self-insurance by the Servicer or the Special Servicer, as applicable, with
respect to a Fidelity Bond would not by reason thereof cause Fitch to qualify,
downgrade or withdraw the then-current rating assigned to any of the
Certificates that are currently being rated by Fitch), the Servicer or the
Special Servicer, respectively, shall be allowed to provide self-insurance with
respect to a Fidelity Bond and such errors and omissions policy. The amount of
coverage shall be at least equal to the coverage that would be required by FNMA
or FHLMC or in an amount that would meet the requirements of prudent
institutional commercial mortgage loan servicers for similar transactions, with
respect to the Servicer or the Special Servicer if the Servicer or the Special
Servicer, as applicable, were servicing and administering the Loans or Specially
Serviced Loans, as applicable, for FNMA or FHLMC. Coverage of the Servicer or
the Special Servicer under a policy or bond obtained by an Affiliate of the
Servicer or the Special Servicer and providing the coverage required by this
Section 3.07(c) shall satisfy the requirements of this Section 3.07(c).

            The Special Servicer and the Servicer will promptly report in
writing to the Trustee any material changes that may occur in their respective
Fidelity Bonds, if any, and/or their respective errors and omissions Insurance
Policies, as the case may be, and will furnish to the Trustee copies of all
binders and policies or certificates evidencing that such bonds, if any, and
insurance policies are in full force and effect.

            (d) During all such times as any Mortgaged Property shall be in a
federally designated special flood hazard area (if flood insurance has been made
available), the Servicer will use its reasonable best efforts to cause the
related Mortgagor (in accordance with applicable law and the terms of the Loan
Documents) to maintain, and, if the related Mortgagor shall default in its
obligation to so maintain, shall itself maintain to the extent available at
commercially reasonable rates (as determined by the Servicer in accordance with
the Servicing Standard), flood insurance in respect thereof, but only to the
extent the related Loan permits the mortgagee to require such coverage and the
maintenance of such coverage is consistent with the Servicing Standard. Such
flood insurance shall be in an amount equal to the least of (i) the unpaid
principal balance of the related Loan, (ii) the maximum amount of insurance
which is available under the Flood Disaster Protection Act of 1973, as amended,
and (iii) the amount required by the Loan. If the cost of any insurance
described above is not borne by the Mortgagor, the Servicer shall promptly make
a Servicing Advance for such costs, subject to Section 3.03(c).

            (e) During all such times as any REO Property shall be located in a
federally designated special flood hazard area, the Special Servicer will cause
to be maintained, to the extent available at commercially reasonable rates (as
determined by the Special Servicer in accordance with the Servicing Standard), a
flood insurance policy meeting the requirements of the current guidelines of the
Federal Insurance Administration in an amount representing coverage not less
than the maximum amount of insurance which is available under the Flood Disaster
Protection Act of 1973, as amended. The cost of any such flood insurance with
respect to an REO Property shall be an expense of the Trust Fund payable out of
the related REO Account pursuant to Section 3.16(c) or, if the amount on deposit
therein is insufficient therefor, paid by the Servicer as a Servicing Advance.

            (f) Notwithstanding the provisions of the related Mortgage and any
other provision of this Agreement, but otherwise in accordance with the
Servicing Standard, the Servicer shall not require any Mortgagor to obtain
insurance in excess of the amounts of coverage and deductibles heretofore
required by the applicable Mortgage Loan Seller in connection with the
origination of the related Loan (such amounts, with respect to each Loan, the
"Origination Required Insurance Amounts"), unless the Servicer determines, in
accordance with the Servicing Standard, that such Origination Required Insurance
Amounts would not be prudent for property of the same type as the related
Mortgaged Property. The Servicer shall require that each policy of
business-interruption insurance maintained by a Mortgagor have a minimum term of
at least twelve months. The Depositor shall provide evidence to the Servicer of
the Origination Required Insurance Amounts for each Mortgaged Property.

            Section 3.08   Enforcement of Due-On-Sale and Due-On-Encumbrance
Clauses; Assumption Agreements; Defeasance Provisions.

            (a) (i) As to each Loan which contains a provision in the nature of
a "due-on-sale" clause, which by its terms:

                  (A) provides that such Loan shall (or may at the mortgagee's
            option) become due and payable upon the sale or other transfer of an
            interest in the related Mortgaged Property or the related Borrower
            or

                  (B) provides that such Loan may not be assumed without the
            consent of the mortgagee in connection with any such sale or other
            transfer,

the Servicer shall provide notice to the Special Servicer of any request for a
waiver thereof, and the Special Servicer (whether or not such Loan is a
Specially Serviced Loan) shall enforce such due-on-sale clause, unless the
Special Servicer determines, in accordance with the Servicing Standard, that (1)
not declaring an Event of Default (as defined in the related Mortgage) or (2)
granting such consent would be likely to result in a greater recovery (or an
equal recovery, provided the other conditions for an assumption or waiver of a
due-on-sale clause are met), on a present value basis (discounting at the
related Mortgage Rate), than would enforcement of such clause or the failure to
grant such consent. If the Special Servicer determines that (1) not declaring an
Event of Default (as defined in the related Mortgage) or (2) granting such
consent would be likely to result in a greater recovery (or an equal recovery,
provided the other conditions for an assumption or waiver of a due-on-sale
clause are met), the Special Servicer shall take or enter into an assumption
agreement from or with the proposed transferee as obligor thereon, provided that
(x) the credit status of the prospective transferee is in compliance with the
Special Servicer's regular commercial mortgage loan origination criteria or the
Servicing Standard and the terms of the related Mortgage and (y) with respect to
any Loan which is a Significant Loan, the Special Servicer shall have received
written confirmation from each of the Rating Agencies that such assumption would
not, in of itself, cause a downgrade, qualification or withdrawal of any of the
then-current ratings assigned to the Certificates.

               (ii) Notwithstanding the provisions of any Loan, foreclosure by a
      Mezzanine Loan Holder on any Mezzanine Loan Collateral securing a
      Mezzanine Loan to an affiliate of the related Borrower shall not, for
      purposes of this Agreement, be deemed to be a violation of the due-on-sale
      clause of the related Loan Documents or of clause (i) of this Section
      3.08(a) so long as the foreclosing party is a Permitted Mezzanine Loan
      Holder.

               (iii) Neither the Servicer nor the Special Servicer shall (x)
      consent to the foreclosure of any Mezzanine Loan other than by a Permitted
      Mezzanine Loan Holder or (y) consent to the transfer of any Mezzanine Loan
      except to a Permitted Mezzanine Loan Holder, except, in each case, as
      otherwise provided in Section 3.08(a)(i). Neither the consent of the
      Servicer nor the consent of the Special Servicer shall be required for the
      foreclosure by a Permitted Mezzanine Loan Holder if an event of default
      has been declared under the related Loan (and each Rating Agency has been
      notified of such event of default). In no event shall a Mezzanine Loan
      Holder be required to pay any assumption fee, modification fee or other
      service charge in connection with any foreclosure upon Mezzanine Loan
      Collateral, transfer of ownership of the related Mortgaged Property to
      such Mezzanine Loan Holder and/or assumption of the related Loan. Nothing
      herein shall prevent a Mezzanine Loan Holder from appointing a receiver or
      trustee with respect to any Mezzanine Loan Collateral, foreclosing upon
      any reserves, escrow accounts or cash collateral accounts pledged under
      the related Mezzanine Loan (provided none of such accounts have been
      pledged under the related Loan) or otherwise taking an assignment of any
      cash flows from any Mezzanine Loan Collateral.

            (b) As to each Loan which contains a provision in the nature of a
"due-on-encumbrance" clause, which by its terms:

               (i)provides that such Loan shall (or, at the mortgagee's option,
      may) become due and payable upon the creation of any additional lien or
      other encumbrance on the related Mortgaged Property or

               (ii) requires the consent of the mortgagee to the creation of any
      such additional lien or other encumbrance on the related Mortgaged
      Property,

the Servicer shall provide notice to the Special Servicer of any request for a
waiver thereof, and the Special Servicer (whether or not such Loan is a
Specially Serviced Loan) shall enforce such due-on-encumbrance clause and in
connection therewith shall (i) accelerate payments thereon or (ii) withhold its
consent to such lien or encumbrance unless the Special Servicer (x) determines,
in accordance with the Servicing Standard, that (1) not accelerating payments on
such Loan or (2) granting such consent would result in a greater recovery on a
present value basis (discounting at the related Mortgage Rate) than would
enforcement of such clause or the failure to grant such consent and (y) receives
prior written confirmation from each of the Rating Agencies that (1) not
accelerating such payments or (2) granting such consent would not, in and of
itself, cause a downgrade, qualification or withdrawal of any of the
then-current ratings assigned to the Certificates.

            (c) Nothing in this Section 3.08 shall constitute a waiver of the
Trustee's right, as the mortgagee of record, to receive notice of any assumption
of a Loan, any sale or other transfer of the related Mortgaged Property or the
creation of any additional lien or other encumbrance with respect to such
Mortgaged Property.

            (d) Except as otherwise permitted by Section 3.20, the Special
Servicer shall not agree to modify, waive or amend any term of any Loan in
connection with the taking of, or the failure to take, any action pursuant to
this Section 3.08.

            (e) Notwithstanding any other provisions of this Section 3.08, the
Servicer may grant 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 Loan to such easement or right-of-way, provided that the Servicer
shall have determined (i) in accordance with the Servicing Standard that such
easement or right-of-way will not materially interfere with the then-current use
of the related Mortgaged Property or the security intended to be provided by
such Mortgage and will not materially or adversely affect the value of such
Mortgaged Property and (ii) that no REMIC created hereunder will fail to qualify
as a REMIC as a result thereof and that no tax on "prohibited transactions" or
"contributions" after the Closing Date would be imposed on either REMIC created
hereunder as a result thereof. The Servicer shall use reasonable efforts,
consistent with the Servicing Standard, to cause the Mortgagor, at the
Mortgagor's expense, to obtain legal advice to make the determination described
in clause (ii). If the Servicer is unable to cause the Mortgagor to obtain such
legal advice, the Servicer shall obtain such legal advice, if necessary, in
accordance with the Servicing Standard, and the cost thereof shall be deemed a
Servicing Advance.

            (f) With respect to any Loan which permits release of Mortgaged
Properties through defeasance (each, a "Defeasance Loan"), to the extent
permitted under the related Loan Documents:

               (i) The Servicer, with the consent of the Special Servicer, shall
      effect such defeasance only through the purchase of U.S. government
      obligations satisfying both the defeasance rule of the REMIC Provisions
      ("Defeasance Collateral") and the requirements of clause (i) of the
      definition of Permitted Investments herein which purchase shall be made in
      accordance with the terms of such Loan; provided, however, that the
      Servicer shall not accept the amounts paid by the related Borrower to
      effect defeasance until such U.S. government obligations have been
      identified and an Independent accounting firm has provided the Servicer a
      comfort letter that states that such defeasance is in the correct amount
      and is in other respects in accordance with the terms of such Loan and
      provided, further, that no defeasance shall be accepted within two years
      after the Closing Date.

               (ii) If such Loan permits the assumption of the obligations of
      the related Borrower by a successor mortgagor, the Servicer, with the
      consent of the Special Servicer, shall cause the Borrower to pay all
      expenses incurred in connection with the establishment of a successor
      Borrower that shall be a Single-Purpose Entity and cause an assumption by
      such successor Borrower of the defeased obligations under the related
      Note. The Servicer shall be permitted to establish a single Single-Purpose
      Entity to assume the defeased obligations under all of the Loans that have
      been defeased.

               (iii) The Servicer shall require an Opinion of Counsel from the
      related Borrower, at such Borrower's expense, to the effect that the
      Trustee has a first priority security interest in the defeasance deposit
      and the related U.S. government obligations and that the assignment
      thereof is valid and enforceable.

               (iv) The Servicer shall obtain at the related Borrower's expense
      a certificate from an Independent certified public accountant certifying
      that the U.S. government obligations are sufficient to make all scheduled
      payments under the related Note.

               (v) Prior to permitting release of any Mortgaged Property through
      defeasance, if such defeasance is a partial defeasance or such Mortgaged
      Property relates to a Loan that is (x) a Loan, (y) part of a group of
      Crossed Loans or (z) part of a group of Loans made to affiliated Borrowers
      that, in each case, in the aggregate, represents one of the ten largest
      loans (which for the purposes of this definition shall include groups of
      Crossed Loans and groups of Loans made to affiliated Borrowers), the
      Servicer shall obtain, at the expense of the related Borrower, written
      confirmation from Fitch that such defeasance would not, in and of itself,
      result in a downgrade, qualification or withdrawal of any of the
      then-current ratings assigned to the Certificates. Prior to permitting
      release of any Mortgaged Property through defeasance, in the event the
      conditions specified in (i) through (iv) above are not met, the Borrower
      shall be required to obtain such written confirmation from DCR and
      Moody's.

               (vi) Neither the Servicer nor the Special Servicer shall permit
      the release of any Mortgaged Property through defeasance unless the
      related Borrower establishes to the satisfaction of the Servicer or the
      Special Servicer that the lien on such Mortgaged Property will be released
      to facilitate the disposition thereof or to facilitate any other customary
      commercial transaction.

               (vii) Prior to permitting release of any Mortgaged Property
      through defeasance, if the related Loan so requires and provides for the
      related Borrower to pay the cost thereof, the Servicer shall require such
      Borrower to deliver an Opinion of Counsel to the effect that such release
      will not cause either REMIC created hereunder to fail to qualify as a
      REMIC at any time that any Certificates are outstanding or cause a tax to
      be imposed on the Trust Fund under the REMIC Provisions.

               (viii) Neither the Servicer nor the Special Servicer shall permit
      a partial defeasance with respect to any Loan unless the value of the
      Defeasance Collateral is at least the amount provided in the related Loan
      Documents.

Any costs to the Servicer of obtaining legal advice to make the determinations
required to be made by it pursuant to this Section 3.08(f), or obtaining the
Rating Agency confirmations required by this Section 3.08(f), shall be borne by
the related Borrower as a condition to the Servicer's obligation to effect the
defeasance of the related Loan or advanced as a Servicing Advance by the
Servicer.

            (g) With respect to any Loan having the benefit of a Residual Value
Policy, neither the Servicer nor the Special Servicer shall agree to any
modification to, or waiver of any term of, the related Residual Value Policy (i)
without written confirmation by each Rating Agency that such modification or
waiver would not, in and of itself, result in a downgrade, qualification or
withdrawal of any of the current ratings assigned to the Certificates and (ii)
without a determination that such modification or waiver will not constitute a
"significant modification" under the REMIC Provisions. Any costs to the Servicer
of obtaining legal advice to make the determinations required to be made by it
pursuant to this Section 3.08(g), or obtaining the Rating Agency confirmations
required by this Section 3.08(g), shall be borne by the related Borrower as a
condition to the Servicer's obligation to agree to any modification or waiver
referred to in the preceding sentence.

            (h) With respect to any Loan, neither the Servicer nor the Special
Servicer shall permit the related Borrower to substitute any real property, any
rights with respect to real property, or any other property interest whatsoever
for the Mortgaged Property securing such Loan as of the Closing Date without
receipt of an Opinion of Counsel, at the expense of the Borrower, to the effect
that the substitution will not cause the related Loan to fail to qualify as a
"qualified mortgage" as defined under Section 860G(a)(3) of the Code while such
Loan is owned by the Lower-Tier REMIC.

            (i) With respect to any Loan pursuant to which the Borrower may not
incur additional indebtedness encumbering the related Mortgaged Property without
the consent of the lender, neither the Servicer nor the Special Servicer shall
consent to such additional debt without written confirmation to the Servicer or
the Special Servicer, as applicable, and the Trustee by each Rating Agency that
such modification or waiver would not, in and of itself, result in a downgrade,
qualification or withdrawal of any of the current ratings assigned to the
Certificates. Any costs to the Servicer of obtaining the Rating Agency
confirmations required by this Section 3.08(i) shall be borne by the related
Borrower as a condition to the Servicer's obligation to agree to any
modification or waiver referred to in the preceding sentence.

            Section 3.09      Realization upon Defaulted Loans.

            (a) The Special Servicer shall, subject to subsections (b) through
(d) of this Section 3.09, exercise reasonable efforts, consistent with the
Servicing Standard, to foreclose upon or otherwise comparably convert (which may
include an REO Acquisition) the ownership of any property securing such Loans as
come into and continue in default as to which no satisfactory arrangements can
be made for collection of delinquent payments, and which are not released from
the Trust Fund pursuant to any other provision hereof. In any case in which a
Mortgaged Property shall have suffered damage such that the complete restoration
of such property is not fully reimbursable by the hazard insurance policies or
flood insurance policies required to be maintained pursuant to Section 3.07, the
Servicer shall not be required to make a Servicing Advance and expend funds
toward the restoration of such property unless the Special Servicer has
determined in its reasonable judgment in accordance with the Servicing Standard
that such restoration will increase the net proceeds of liquidation of such
Mortgaged Property to Certificateholders after reimbursement to the Servicer for
such Servicing Advance and interest thereon and the Servicer has determined that
such Servicing Advance together with accrued and unpaid interest thereon will be
recoverable by the Servicer out of the proceeds of liquidation of such Mortgaged
Property, as contemplated in Section 3.05(a)(iv). The Special Servicer shall be
responsible for all other costs and expenses incurred by it in any such
proceedings (such costs and expenses to be advanced by the Servicer to the
Special Servicer and recoverable by the Servicer as a Servicing Advance),
provided that, in each case, such cost or expense would not, if incurred,
constitute a Nonrecoverable Servicing Advance.

            Nothing contained in this Section 3.09 shall be construed to require
the Servicer or 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 Servicer
or the Special Servicer in its reasonable and good faith judgment taking into
account the factors described in Section 3.18(d) 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 Special
Servicer or the Servicer deems it necessary and prudent for purposes of
establishing the fair market value of any Mortgaged Property securing a
Defaulted Loan, whether for purposes of bidding at foreclosure or otherwise, the
Special Servicer or the Servicer, as the case may be, is authorized to have an
Appraisal performed with respect to such property, the cost of which Appraisal
shall be paid by the Servicer as a Servicing Advance.

            (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 shall be a Servicing Advance) to the effect
      that the holding of such personal property by the Trust Fund will not
      cause the imposition of a tax on either REMIC created hereunder under the
      REMIC Provisions or cause either REMIC created hereunder to fail to
      qualify as a REMIC at any time that any Uncertificated Lower-Tier Interest
      or Certificate is outstanding.

            (c) Notwithstanding the foregoing provisions of this Section 3.09,
the Special Servicer shall not, on behalf of the Trustee, obtain title to a
Mortgaged Property 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, would 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,
unless (as evidenced by an Officer's Certificate to such effect delivered to the
Trustee) the Special Servicer has previously determined in accordance with the
Servicing Standard, based on an Environmental Assessment of such Mortgaged
Property performed within the preceding 12 months by an Independent Person who
regularly conducts Environmental Assessments, that:

               (i) the Mortgaged Property is in compliance with applicable
      environmental laws and regulations or, if not, that taking such actions as
      are necessary to bring the Mortgaged Property in compliance therewith is
      reasonably likely to produce a greater recovery on a present value basis
      than not taking such actions; 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 be required, that
      taking such actions with respect to such Mortgaged Property is reasonably
      likely to produce a greater recovery on a present value basis than not
      taking such actions.

            The cost of any such Environmental Assessment and the cost of any
remedial, corrective or other further action contemplated by clause (i) and/or
clause (ii) of the preceding sentence shall be paid by the Servicer as a
Servicing Advance. If any such Environmental Assessment so warrants, the Special
Servicer shall, at the expense of the Trust Fund, perform such additional
environmental testing as it deems necessary and prudent to determine whether the
conditions described in clauses (i) and (ii) of the second preceding sentence
have been satisfied.

            (d) If (i) the environmental testing contemplated by subsection (c)
above establishes that either of the conditions set forth in clauses (i) and
(ii) of the first sentence thereof has not been satisfied with respect to any
Mortgaged Property securing a Defaulted Loan and (ii) there has been no breach
of any of the representations and warranties set forth in or required to be made
pursuant to Section 6 of the related Mortgage Loan Purchase Agreement for which
the related Mortgage Loan Seller, FINOVA or FINOVA Capital, as applicable, could
be required to repurchase such Defaulted Loan pursuant to Section 7 of the
related Mortgage Loan Purchase Agreement or Section 9.3 of the related FINOVA
Mortgage Loan Purchase Agreement, as applicable, then the Special Servicer shall
take such action as it deems to be in the best economic interest of the Trust
Fund and consistent with the Servicing Standard (other than proceeding to
acquire title to the Mortgaged Property) and is hereby authorized at such time
as it deems appropriate to release such Mortgaged Property from the lien of the
related Mortgage.

            (e) The Special Servicer shall provide written reports and a copy of
any Environmental Assessments to the Custodian, the Servicer and the Certificate
Owners of the Controlling Class monthly regarding any actions taken by the
Special Servicer with respect to any Mortgaged Property securing a Defaulted
Loan as to which the environmental testing contemplated in subsection (c) above
has revealed that either of the conditions set forth in clauses (i) and (ii) of
the first sentence thereof has not been satisfied, in each case the earlier to
occur of satisfaction of both such conditions, repurchase of the related Loan by
the related Mortgage Loan Seller, FINOVA or FINOVA Capital, as applicable, or
release of the lien of the related Mortgage on such Mortgaged Property;
provided, however, that with respect to each such report or Environmental
Assessment, if beneficial ownership of the Controlling Class resides in more
than one Certificate Owner, the Special Servicer shall be responsible only for
the expense of providing the first such copy thereof and shall be entitled to
reimbursement from the Trust Fund for the expense of any additional copies so
provided. The Custodian shall, upon request, forward all such reports to the
Certificateholders and each Rating Agency promptly following the receipt
thereof.

            (f) The Servicer shall report to the Internal Revenue Service and
the related Mortgagor, in the manner required by applicable law, the information
required to be reported regarding any Mortgaged Property which is abandoned or
foreclosed, the receipt of mortgage interests received in a trade or business
and the forgiveness of indebtedness with respect to any mortgaged property
required by Sections 6050J, 6050H and 6050P, respectively, of the Code. The
Special Servicer shall provide the Servicer with such information or reports as
the Servicer deems necessary to fulfill its obligations under this Section
3.09(f) promptly upon the Servicer's request therefor. The Servicer shall
deliver a copy of any such report to the Trustee and the Special Servicer.

            (g) The Special Servicer shall have the right to determine, in
accordance with the Servicing Standard, the advisability of the maintenance of
an action to obtain a deficiency judgment if the state in which the Mortgaged
Property is located and the terms of the Loan permit such an action.

            (h) The Special Servicer shall maintain accurate records, prepared
by one of its Servicing Officers, of each Final Recovery Determination in
respect of a Defaulted Loan or REO Property and the basis thereof. Each Final
Recovery Determination shall be evidenced by an Officer's Certificate delivered
to the Trustee and the Servicer no later than the next succeeding P&I Advance
Determination Date.

            Section 3.10  Custodian to Cooperate; Release of Mortgage Files.

            (a) Upon the payment in full of any Loan, or the receipt by the
Servicer or the Special Servicer, as the case may be, of a notification that
payment in full shall be escrowed in a manner customary for such purposes, the
Servicer or Special Servicer, as the case may be, will immediately notify the
Custodian and request delivery of the related Mortgage File. Any such notice and
request shall be in the form of a Request for Release signed by a Servicing
Officer 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 Collection Account pursuant to Section 3.04(a) or remitted to
the Servicer to enable such deposit, have been or will be so deposited. Within
six Business Days (or within such shorter period as release can reasonably be
accomplished if the Servicer notifies the Trustee of an exigency) of receipt of
such notice and request, the Trustee (or, to the extent provided in Section
3.01(b), the Servicer or the Special Servicer, as applicable) shall execute such
instruments of satisfaction, deeds of reconveyance and other documents as shall
have been furnished to it by the Servicer, and the Custodian shall release and
deliver the related Mortgage File to the Servicer or Special Servicer, as the
case may be. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Collection
Account.

            (b) From time to time as is appropriate for servicing or foreclosure
of any Loan, the Servicer or the Special Servicer shall deliver to the Custodian
a Request for Release signed by a Servicing Officer. Upon receipt of the
foregoing, the Custodian shall deliver the Mortgage File or any document therein
to the Servicer or the Special Servicer (or a designee), as the case may be.
Upon return of the Mortgage File to the Custodian, the Custodian shall execute
an acknowledgment of receipt.

            (c) Within seven Business Days (or within such shorter period as
delivery can reasonably be accomplished if the Special Servicer notifies the
Trustee of an exigency) of receipt thereof, the Trustee shall execute and
deliver to the Special Servicer any court pleadings, requests for trustee's sale
or other documents necessary to the release of a Loan or REO Loan, or to
foreclosure or trustee's sale in respect of a Mortgaged Property or to any legal
action brought to obtain judgment against any Mortgagor on the Note or Mortgage
or to obtain a deficiency judgment, or to enforce any other remedies or rights
provided by the Note or Mortgage or otherwise available at law or in equity. The
Special Servicer shall be responsible for the preparation of all such documents
and pleadings. When submitted to the Trustee for signature, such documents or
pleadings shall be accompanied by 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, that the
proposed action is in the best interest of the Certificateholders 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 Servicer shall
be entitled to receive the Servicing Fee with respect to each Loan and REO Loan
(including Specially Serviced Loans, Defeasance Loans and Additional Collateral
Loans) at the Servicing Fee Rate (in accordance with the same terms of the
related Note as are applicable to the accrual of interest at the Mortgage Rate),
computed on the basis of the Stated Principal Balance of such Loan on a 30/360
basis. The Servicing Fee with respect to any Loan or REO Loan shall cease to
accrue if a Liquidation Event occurs in respect thereof. The Servicing Fee shall
be payable monthly, on a loan-by-loan basis, from payments of interest on each
Loan and REO Revenues allocable as interest on each REO Loan. In no event will
the Servicer or any Primary Servicer be entitled to retain a servicing fee from
the amount of any P&I Advance, regardless of whether the related Borrower is
obligated to reimburse Servicing Fees or Primary Servicing Fees.

            The Servicer, on behalf of itself or any Primary Servicer, shall be
entitled to recover unpaid Servicing Fees and Primary Servicing Fees in respect
of any Loan or REO Loan out of that portion of related payments, Insurance and
Condemnation Proceeds, Liquidation Proceeds and REO Revenues (in the case of an
REO Loan) allocable as recoveries of interest, to the extent permitted by
Section 3.05(a). The right to receive the Servicing Fee (and, except to the
extent set forth in the Primary Servicing Agreement with respect to a Primary
Servicer and except as set forth in this Section 3.11(a), the related Primary
Servicing Fee) may not be transferred in whole or in part except in connection
with the transfer of all of the Servicer's responsibilities and obligations
under this Agreement. The CSFB Mortgage Loan Seller shall pay the annual fees of
each Rating Agency directly to each Rating Agency. The parties hereto
acknowledge that the annual fees of each Rating Agency allocable to the MS Loans
have been paid on or prior to the Closing Date by the MS Mortgage Loan Seller.

            Additional servicing compensation in the form of (i) one-half of all
assumption fees paid by the Mortgagors on all Loans that are not Specially
Serviced Loans (but only to the extent that all amounts then due and payable
with respect to such Loans (except for interest on Advances then outstanding)
have been paid), (ii) charges for beneficiary statements or demands and amounts
collected for checks returned for insufficient funds, (iii) all commercially
reasonable fees received on or with respect to Loan modifications for which the
Servicer is responsible pursuant to Section 3.20(a)(ii) (but only to the extent
actually collected from the related Mortgagor and only to the extent that all
amounts then due and payable after giving effect to any modification with
respect to the related Loan have been paid), (iv) reasonable and customary
consent fees and fees in connection with defeasance, if any, and (v) other
customary charges, in each case only to the extent actually paid by the related
Mortgagor, shall be retained by the Servicer and shall not be required to be
deposited in the Collection Account pursuant to Section 3.04(a).

            The Servicer also shall be entitled to additional servicing
compensation in the form of: (i) Penalty Charges received on each Loan (other
than Specially Serviced Loans) but only to the extent actually paid by the
related Mortgagor and to the extent that all amounts then due and payable with
respect to such Loan (including outstanding interest on all Advances accrued
with respect to such Loan) have been paid to the Servicer; (ii) interest or
other income earned on deposits relating to the Trust Fund in the Collection
Account, any Cash Collateral Account and any Lock-Box Account in accordance with
Section 3.06(b) (but only to the extent of the Net Investment Earnings, if any,
with respect to each such account for each period from any Distribution Date to
the immediately succeeding P&I Advance Date); (iii) interest earned on deposits
in the Servicing Accounts that is not required by applicable law or the related
Loan to be paid to the Mortgagor; and (iv) collections representing Prepayment
Interest Excess for any Distribution Date (other than the greater of (x) with
respect to any Loan whose terms expressly permit collections of interest through
the following Due Date in connection with any voluntary Principal Prepayment and
(y) the aggregate of the Uncovered Prepayment Interest Shortfalls for such
Distribution Date). Notwithstanding anything to the contrary in clause (i) of
the first sentence of this paragraph or in the last paragraph of Section
3.11(b), (x) the Servicer shall be entitled to that portion, if any, of a
Penalty Charge collected on a Specially Serviced Loan that accrued prior to the
related Servicing Transfer Event and (y) if the Special Servicer has partially
waived any Penalty Charge part of which accrued prior to the related Servicing
Transfer Event, any collections in respect of such Penalty Charge shall be
shared pro rata by the Servicer and the Special Servicer based on the respective
portions of such Penalty Charge to which they would otherwise have been
entitled.

            Wells Fargo Bank, National Association ("Wells Fargo"), as initial
Servicer hereunder, shall also be entitled to receive all Primary Servicing Fees
on any Loan and REO Loan (including any Specially Serviced Loan and Defeasance
Loan) which is not serviced by a Primary Servicer, computed on the basis of the
related Stated Principal Balance and for the same period and in the same manner
respecting which any related interest payment due (or deemed to be due) on the
related Loan is computed. Wells Fargo's right to receive such Primary Servicing
Fees in accordance with the provisions hereof shall not be terminated under any
circumstance, including transfer of the servicing or subservicing of the Loans
to another entity. Wells Fargo shall be permitted to assign such Primary
Servicing Fees to any party without restriction.

            Except as specifically provided herein, the 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, except for premiums for any blanket Insurance Policy
insuring against hazard losses pursuant to Section 3.07), if and to the extent
such expenses are not payable directly out of the Collection Account, and the
Servicer shall not be entitled to reimbursement therefor except as expressly
provided in this Agreement.

            Notwithstanding the foregoing paragraphs of this Section 3.11, the
Servicing Fee on any Loan, other than a Specially Serviced Loan, and the
investment income earned on any Principal Prepayment made on such Loan during a
given Due Period, and due the Servicer on the related Distribution Date shall be
reduced by the Prepayment Interest Shortfall, if any, on such Loan for such
Distribution Date; provided, however, that with respect to any Additional
Collateral Loans as to which Additional Collateral is paid as a Principal
Prepayment, neither the Servicing Fee on such Loan, nor the investment income
earned on any such Principal Prepayment, shall be reduced by the Prepayment
Interest Shortfall.

            (b) As compensation for its activities hereunder, the Special
Servicer shall be entitled to receive the Special Servicing Fee with respect to
each Specially Serviced Loan (other than the L'Enfant Participation) and REO
Loan (other than the L'Enfant Participation). As to each such Specially Serviced
Loan and REO Loan, the Special Servicing Fee shall accrue at the Special
Servicing Fee Rate (in accordance with the same terms of the related Note as are
applicable to the accrual of interest at the Mortgage Rate) and shall be
computed on the basis of the Stated Principal Balance of such Specially Serviced
Loan and for the same period respecting which any related interest payment due
on such Specially Serviced Loan or deemed to be due on such REO Loan is
computed. The Special Servicing Fee with respect to any Specially Serviced Loan
or REO Loan shall cease to accrue if a Liquidation Event occurs in respect
thereof. The Special Servicing Fee shall be payable monthly, on a loan-by-loan
basis, to the extent permitted by Section 3.05(a). The right to receive the
Special Servicing 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 this Agreement. The Special Servicing Fee with respect to
any related Other Mortgage Loan shall be payable under the related Co-Lender
Agreement (which amount may be netted against amounts payable to the holder of
the Other Note).

            Additional servicing compensation in the form of (i) all assumption
fees on all Specially Serviced Loans, (ii) one-half of all assumption fees on
any Loans other than Specially Serviced Loans and (iii) all commercially
reasonable extension fees and all fees received on or with respect to Loan
modifications for which the Special Servicer is responsible pursuant to Section
3.20(a), but only to the extent actually collected from the related Mortgagor
and only to the extent that all amounts then due and payable after giving effect
to any modification with respect to the related Loan (including those payable to
the Servicer pursuant to Section 3.11(a)) have been paid, shall be promptly paid
to the Special Servicer by the Servicer and shall not be required to be
deposited in the Collection Account pursuant to Section 3.04(a).

            The Special Servicer shall also be entitled to additional servicing
compensation in the form of a Workout Fee with respect to each Corrected Loan at
the Workout Fee Rate. The "Workout Fee Rate" means (i) 1.0% for any Loan with a
Stated Principal Balance of less than $10,000,000, (ii) 0.75% for any Loan with
a Stated Principal Balance equal to or greater than $10,000,000 but less than
$20,000,000 and (iii) 0.5% for any Loan with a Stated Principal Balance equal to
or greater than $20,000,000, applied to each collection of interest and
principal (including scheduled payments, prepayments, Balloon Payments and
payments at maturity) received on such Loan for so long as it remains a
Corrected Loan. The Workout Fee with respect to any Corrected Loan will cease to
be payable if such Loan again becomes a Specially Serviced Loan; provided that a
new Workout Fee will become payable if and when such Loan again becomes a
Corrected Loan. If the Special Servicer is terminated (other than for cause or
by resignation), it shall retain the right to receive any and all Workout Fees
payable with respect to Loans that became Corrected Loans during the period that
it acted as Special Servicer and were Corrected Loans at the time of such
termination (and the successor Special Servicer shall not be entitled to any
portion of such Workout Fees), in each case until the Workout Fee for any such
loan ceases to be payable in accordance with the terms hereof.

            A Liquidation Fee will be payable with respect to each Specially
Serviced Loan as to which the Special Servicer receives any Liquidation Proceeds
subject to the exceptions set forth in the definition of Liquidation Fee. As to
each Specially Serviced Loan, the Liquidation Fee will be payable out of, and
will be calculated by application of a "Liquidation Fee Rate" of (i) 1.0% for
any Loan with a Stated Principal Balance of less than $10,000,000, (ii) 0.75%
for any Loan with a Stated Principal Balance equal to or greater than
$10,000,000 but less than $20,000,000, and (iii) 0.5% for any Loan with a Stated
Principal Balance equal to or greater than $20,000,000, in each case expressed
as a percentage of net liquidation proceeds received with respect to such
Specially Serviced Loan.

            Notwithstanding anything to the contrary described above, no
Liquidation Fee will be payable based on, or out of, Liquidation Proceeds
received in connection with the repurchase of any Loan by any Mortgage Loan
Seller, FINOVA or FINOVA Capital for a breach of representation or warranty or
by any Mortgage Loan Seller for defective or deficient Loan documentation, the
purchase of any Specially Serviced Loan by the Servicer or the Special Servicer,
the purchase by the Holders of the Class V-1 or Class V-2 Certificates, of any
ARD Loan pursuant to Section 9.03 or the purchase of all of the Loans and REO
Properties in connection with an optional termination of the Trust Fund pursuant
to Section 9.01. If, however, Liquidation Proceeds are received with respect to
any Corrected Loan and the Special Servicer is properly entitled to a Workout
Fee, such Workout Fee will be payable based on and out of the portion of such
Liquidation Proceeds that constitute principal and/or interest on such Loan.

            The Special Servicer will also be entitled to additional fees in the
form of Penalty Charges on each Specially Serviced Loan (but only to the extent
actually collected from the related Mortgagor and to the extent that all amounts
then due and payable with respect to such Specially Serviced Loan (including
outstanding interest on all Advances accrued with respect to such Specially
Serviced Loan) have been paid to the Special Servicer). The Special 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, other than management fees in respect of REO
Properties, due and owing to any of its Sub-Servicers and the premiums for any
blanket Insurance Policy obtained by it insuring against hazard losses pursuant
to Section 3.07), if and to the extent such expenses are not payable directly
out of the Collection Account or the REO Account, and the Special Servicer shall
not be entitled to reimbursement therefor except as expressly provided in this
Agreement.

            On the Closing Date, the Servicer shall deliver to the Certificate

Section 3.12(c) with respect to REO Loans and Specially Serviced Loans shall be
subject to the satisfaction of the Special Servicer's obligations under Section
3.12(f). In the absence of manifest error, the Servicer shall be entitled to

      related L'Enfant Servicer or L'Enfant Special Servicer in the case of any

      such reports from the L'Enfant Servicer or L'Enfant Special Servicer), an
      Operating Statement Analysis Report and NOI Adjustment Worksheet for the
      related Mortgaged Property or REO Property as of the end of the preceding
      fiscal year, together with copies of the operating statements and rent

      information to the Servicer and, with respect to operating statements and
      rent rolls for Specially Serviced Loans and REO Properties, to the extent
      timely delivered by the Special Servicer to the Servicer), for the related
      Mortgaged Property or REO Property as of the end of the preceding fiscal
      year. The Servicer shall use its best reasonable efforts (but shall not be
      required to institute litigation) to obtain said annual operating
      statements and rent rolls with respect to each of the Loans, other than
      Specially Serviced Loans or REO Loans, which efforts shall include sending
      a letter to the related Borrower each quarter (followed up with telephone
      calls) requesting such annual operating statements and rent rolls until
      they are received, to the extent such action is consistent with applicable
      law and the terms of the Loans.

               (ii) The Servicer shall maintain an Operating Statement Analysis
      Report for each Mortgaged Property (other than any such Mortgaged Property
      which is REO Property or constitutes security for a Specially Serviced
      Loan) that shall be updated by the Servicer and delivered to the
      Certificate Administrator within 30 days after receipt by the Servicer of
      updated operating statements for such Mortgaged Property, provided, that
      the Servicer shall not be required to update the Operating Statement
      Analysis Reports more often than quarterly.

            The Special Servicer will be required pursuant to Section 3.12(g) to

Remittance Date, the Servicer shall prepare and deliver to the Trustee and the
Certificate Administrator, the Rating Agencies and the Special Servicer, a
Servicer Watch List of all Loans that the Servicer has determined are in
jeopardy of becoming a Specially Serviced Loan. For this purpose, the following
Loans shall be deemed to be Loans that are in jeopardy of becoming Specially
Serviced Loans: (i) Loans having a current Debt Service Coverage Ratio that is
80% or less of the Underwritten Debt Service Coverage Ratio or having a Debt
Service Coverage Ratio that is less than 1.00x or .90x (for Loans secured by
Mortgaged Properties that are or include one or more commercial cooperatives,
resort cooperatives or residential cooperative apartment buildings with five or
more cooperative units or a condominium unit that comprises the residential and
commercial buildings), (ii) Loans as to which any required inspection of the
related Mortgaged Property conducted by the Servicer indicates a problem that
the Servicer determines can reasonably be expected to materially adversely
affect the cash flow generated by such Mortgaged Property, (iii) Loans which
have come to the Servicer's attention in the performance of its duties under
this Agreement, that (A) any tenant occupying 25% or more of the space in the

(B) relate to a Borrower or an Affiliate that is the subject of a bankruptcy or
similar proceeding, (iv) Loans that are at least 30 days delinquent in payment,
and (v) Loans that are within 60 days of maturity.

            The Special Servicer shall report to the Servicer any of the
foregoing events promptly upon the Special Servicer having knowledge of such
event. In addition, in connection with their servicing of the Loans, the
Servicer and the Special Servicer shall provide to each other and to the Trustee
and the Certificate Administrator written notice of any event that comes to
their knowledge with respect to a Loan or REO Property that the Servicer or the
Special Servicer, respectively, determines, in accordance with Servicing
Standard, would have a material adverse effect on such Loan or REO Property,
which notice shall include an explanation as to the reason for such material
adverse effect.

            (f) By 4:00 p.m., New York City time, on the first Business Day

            (g) The Special Servicer shall deliver or cause to be delivered to
the Servicer and, upon the request of the Certificate Administrator, the
Trustee, the Depositor or any Rating Agency, to any such requesting party, the
following materials, in each case to the extent that such materials or the
information on which they are based have been received by the Special Servicer:

               (i) Annually, on or before April 30 of each year, commencing in
      April 2000, with respect to each Specially Serviced Loan and REO Loan, an
      Operating Statement Analysis Report and NOI Adjustment Worksheet, both in
      written form and in electronic format reasonably acceptable to the
      Servicer, the Special Servicer and the Certificate Administrator for the
      related Mortgaged Property or REO Property as of the end of the preceding
      calendar year (but only to the extent the Special Servicer has received
      such information from the Servicer at the time of the servicing transfer
      pursuant to Section 3.21 necessary to prepare the related Operating
      Statement Analysis and NOI Adjustment Worksheet on a prospective basis),
      together with copies of the operating statements and rent rolls for the
      related Mortgaged Property or REO Property as of the end of the preceding
      calendar year. The Special Servicer shall use its best reasonable efforts
      (but shall not be required to institute litigation) to obtain said annual
      operating statements and rent rolls with respect to each Mortgaged
      Property constituting security for a Specially Serviced Loan and each REO
      Property, which efforts shall include sending a letter to the related
      Borrower or other appropriate party each quarter (followed up with
      telephone calls) requesting such annual operating statements and rent
      rolls until they are received.

               (ii) The Special Servicer shall maintain an Operating Statement
      Analysis Report, both in written form and in electronic format reasonably
      acceptable to the Servicer, the Special Servicer and the Certificate
      Administrator, for each Mortgaged Property which constitutes security for
      a Specially Serviced Loan or is a REO Property that shall be updated by
      the Special Servicer and delivered to the Servicer within 10 days after
      receipt by the Special Servicer of updated operating statements for each
      such Mortgaged Property, provided, that the Special Servicer shall not be
      required to update the Operating Statement Analysis Reports more often
      than quarterly.

            (h) The Servicer and the Special Servicer hereby agree to deliver to
each Rating Agency any information such Rating Agency may reasonably request.
The Certificate Administrator shall be entitled to rely conclusively on and
shall not be responsible for the content or accuracy of any information provided
to it by the Servicer or the Special Servicer pursuant to this Agreement.

            (i) On each Determination Date, the Servicer shall also deliver or
cause to be delivered to the Certificate Administrator and the Rating Agencies a
report stating, with respect to each Credit Tenant and the Guarantor, as of a
date no earlier than three Business Days prior to such Determination Date: (i)
all publicly available ratings for each Credit Tenant and the Guarantor as of
the Closing Date and as of the date of such report, (ii) all publicly available
ratings for such Credit Tenant or Guarantor included in the report prepared
pursuant to this Section 3.12(i) for the immediately preceding Determination
Date and (iii) whether such Credit Tenant or Guarantor has been placed on credit
watch. To the extent that the information required to be furnished to the
Servicer is based on information required to be provided by the Mortgagor, the
Servicer's obligation to furnish such information will be contingent upon its
receipt of such information from the Mortgagor, provided, however, the Servicer
shall use commercially reasonable efforts, consistent with the Servicing
Standard, to obtain such information from the Mortgagors. The Servicer shall be
entitled to rely on information supplied by the Mortgagor without independent
verification, and the Certificate Administrator shall be entitled to rely on
information supplied by the Servicer without independent verification. The
Servicer shall be entitled to attach any reasonable disclaimer with respect to
information provided by third parties or any assumptions required to be made in
such report.

            Section 3.13      Annual Statement as to Compliance.

            The Servicer and the Special Servicer (the "reporting person") each
shall deliver to the Trustee, the Certificate Administrator, the Depositor and
the Rating Agencies, on or before April 15 of each year, beginning with April
15, 2000, an Officer's Certificate stating, as to each signatory thereof, (i)
that a review of the servicing operations of the reporting person during the
preceding calendar year (or such shorter period from the Closing Date to the end
of the related calendar year) and of its performance under this Agreement has
been made under such officer's supervision, (ii) that, to the best of such
officer's knowledge, based on such review, the reporting person has fulfilled
all of its obligations under this Agreement in all material respects throughout
such year (or such shorter period), or, if there has been a material default in
the fulfillment of any such obligation, specifying each such default known to
such officer, the nature and status thereof and what action it proposes to take
with respect thereto, (iii) that, to the best of such officer's knowledge, each
related sub-servicer has fulfilled its obligations under its sub-servicing
agreement in all material respects, or, if there has been a material default in
the fulfillment of such obligations, specifying each such default known to such
officer and the nature and status thereof, and (iv) whether it has received any
notice regarding qualification, or challenging the status, of any REMIC created
hereunder as a REMIC from the IRS or any other governmental agency or body. The
Trustee shall deliver such Officer's Certificate, upon request, to any
Certificateholder.

            Section 3.14      Reports by Independent Public Accountants.

            On or before April 15 of each year, beginning with April 15, 2000,
the Servicer and the Special Servicer (the "reporting person"), each at the
reporting person's expense, shall cause a firm of nationally recognized
Independent public accountants (who may also render other services to the
reporting person) which is a member of the American Institute of Certified
Public Accountants to furnish a statement (an "Accountant's Statement") to the
Certificate Administrator, the Trustee, the Depositor and the Rating Agencies,
to the effect that such firm has examined the servicing operations of the
reporting person for the previous calendar year (or portions thereof) and that,
on the basis of such examination conducted substantially in compliance with the
Uniform Single Attestation Program ("USAP") for Mortgage Bankers or the Audit
Program for Mortgages (the "Audit Program") serviced for FHLMC, such firm
confirms that the Servicer or the Special Servicer, as the case may be, complied
with the minimum servicing standards identified in USAP or the Audit Program, in
all material respects, except for such significant exceptions or errors in
records that, in the opinion of such firm, the USAP or the Audit Program
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. Each reporting person shall obtain from the related accountants,
or shall prepare, an electronic version of each Accountant's Statement and
provide such electronic version to the Certificate Administrator for filing in
accordance with the procedures set forth in Section 3.27 hereof. With respect to
any electronic version of an Accountant's Statement prepared by the reporting
person, the reporting person shall receive written confirmation from the related
accountants that such electronic version is a conformed copy of the original
Accountant's Statement.

            Section 3.15      Access to Certain Information.

            Each of the Servicer and the Special Servicer shall provide
reasonable access during its normal business hours at each of its principal
servicing offices to any Certificateholder or Certificate Owner that is, or is
affiliated with, a federally insured financial institution, the Trustee, the
Certificate Administrator, the Custodian, the Depositor, each Rating Agency, to
the Servicer or to the Special Servicer, as applicable, and to the OTS, the
FDIC, the Federal Reserve Board and the supervisory agents and examiners of such
boards and such corporations, and any other federal or state banking or
insurance regulatory authority that may exercise authority over any
Certificateholder, access to any documentation regarding the Loans and the Trust
Fund within its control which may be required by this Agreement or by applicable
law.

            Such access shall be afforded without charge (except that the
Servicer and the Special Servicer may charge a reasonable fee for copies and
out-of-pocket costs to parties other than the Rating Agencies) but only upon
reasonable prior written request and during normal business hours at the offices
of the Servicer or the Special Servicer, as the case may be, designated by it.
Nothing in this Section 3.15 shall detract from the obligation of the Servicer
and the Special Servicer to observe any applicable law prohibiting disclosure of
information with respect to the Mortgagors, and the failure of the Servicer or
the Special Servicer to provide access as provided in this Section 3.15 as a
result of such obligation shall not constitute a breach of this Section 3.15.
Nothing herein shall be deemed to require the Servicer or Special Servicer to
confirm, represent or warrant the accuracy of any other Persons' information or
report, included in any communication from the Servicer, the Special Servicer or
Mortgagor. Notwithstanding the above, the Servicer and Special Servicer shall
not have any liability to the Depositor, the Trustee, the Certificate
Administrator, any Certificateholder, any Certificate Owner, the Initial
Purchaser, either Underwriter, any Rating Agency, the L'Enfant Other Servicer or
any Person to whom it delivers information pursuant to and in accordance with
this Section 3.15 or any other provision of this Agreement for federal, state or
other applicable securities law violations relating to the disclosure of such
information. The Servicer and the Special Servicer may each deny any of the
foregoing persons access to confidential information or any intellectual
property which the Servicer or the Special Servicer is restricted by license or
contract from disclosing. Notwithstanding the foregoing, the Servicer and the
Special Servicer shall maintain separate from such confidential information and
intellectual property, all documentation regarding the Loans that is not
confidential.

            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. The Special Servicer, on behalf of the Trust Fund, shall
sell any REO Property prior to the close of the third calendar year beginning
after the year in which the Trust Fund acquires ownership of such REO Property
for purposes of Section 860G(a)(8) of the Code, unless the Special Servicer
either (i) 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 and
the Servicer an Opinion of Counsel (the cost of which shall be paid as a
Servicing Advance), addressed to the Trustee and the Servicer, to the effect
that the holding by the Trust Fund of such REO Property after such period will
not result in the imposition of taxes on "prohibited transactions" of the Trust
Fund or either REMIC created hereunder as defined in Section 860F of the Code or
cause either REMIC created hereunder to fail to qualify as a REMIC for federal
or applicable state tax purposes at any time that any Uncertificated Lower-Tier
Interests or Certificates are outstanding. If the Special Servicer is granted
the REO Extension or obtains the Opinion of Counsel contemplated by clause (ii)
above, the Special Servicer shall sell such REO Property within such period as
is permitted by such REO Extension or such Opinion of Counsel. Any expense
incurred by the Special Servicer in connection with its being granted the REO
Extension or its obtaining the Opinion of Counsel contemplated by clause (ii)
above shall be an expense of the Trust Fund payable out of the Collection
Account pursuant to Section 3.05(a).

            (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 REO Accounts, held on
behalf of the Trustee in trust for the benefit of the Certificateholders, 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, within one Business Day after
receipt, all REO Revenues, Insurance and Condemnation Proceeds and Liquidation
Proceeds received in respect of an REO Property. Funds in the REO Account may be
invested only in Permitted Investments in accordance with Section 3.06. The
Special Servicer shall give notice to the Certificate Administrator and the
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, leasing, 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. On each Determination Date, the
Special Servicer shall withdraw from the REO Account and deposit into the
Collection Account the aggregate of all amounts received in respect of each REO
Property during the most recently ended Due Period, net of any withdrawals made
out of such amounts pursuant to the preceding sentence; provided, however, that
the Special Servicer may retain in such REO Account, in accordance with the
Servicing Standard, such portion of such balance as may be necessary to maintain
a reasonable reserve for repairs, replacements, leasing, management and tenant
improvements and other related expenses for the related REO Property. In
addition, on each Determination Date, the Special Servicer shall provide the
Servicer with a written accounting of amounts deposited in the Collection
Account on such date.

            (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).

            Section 3.17      Management of REO Property.

            (a) If title to any REO Property is acquired, the Special Servicer
shall manage, conserve, protect, operate and lease such REO Property for the
benefit of the Certificateholders solely for the purpose of its timely
disposition and sale in a manner that does not cause such REO Property to fail
to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code or result in the receipt by the Trust Fund of any "income from
non-permitted assets" within the meaning of Section 860F(a)(2)(B) of the Code.
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 in the
best interests of and for the benefit of the Certificateholders (as determined
by the Special Servicer in its good faith and reasonable judgment) and,
consistent therewith, shall withdraw from the REO Account, to the extent of
amounts on deposit therein with respect to such REO Property, funds necessary
for the proper operation, management, leasing and maintenance of such REO
Property, including, without limitation:

               (i) all  Insurance   Policy   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, if
      applicable; and

               (iv) all costs and expenses necessary to maintain and lease 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 clauses (i)
through (iv) above with respect to such REO Property, the Servicer shall advance
from its own funds, as a Servicing Advance, such amount as is necessary for such
purposes unless (as evidenced by an Officer's Certificate delivered to the
Trustee and the Depositor) if such advances would, if made, constitute
Nonrecoverable Servicing Advances. The Special Servicer shall give the Servicer
and the Trustee not less than five Business Days' notice, together with all
information reasonably requested by the Servicer (upon which the Servicer may
conclusively rely) to the extent in the possession of the Special Servicer or
readily obtainable by the Special Servicer before the date on which the Servicer
is requested to make any Servicing Advance with respect to an 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).

            (b) 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, and then only if more than 10% of
      the construction of such building or other improvement was completed
      before default on the related Loan became imminent, all within the meaning
      of Section 856(e)(4)(B) of the Code; or

               (iv) 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 Servicer as a Servicing Advance)
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 Section 3.17(c),
the Special Servicer shall be permitted to cause the Trust Fund to earn "net
income from foreclosure property," subject to the Servicing Standard.

            (c) The Special Servicer shall contract with any Independent
Contractor for the operation and management of any REO Property within 90 days
of the Acquisition Date thereof, 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 an
      expense of the Trust Fund) shall be reasonable and customary in light of
      the nature and locality of the Mortgaged Property;

               (iii) any such contract shall require, or shall be administered
      to require, that the Independent Contractor (A) pay all costs and expenses
      incurred in connection with the operation and management of such REO
      Property, including, without limitation, those listed in subsection (a)
      hereof, and (B) 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(c) 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.

            Section 3.18      Sale of Defaulted Loans and REO Properties.

            (a) Each of the Servicer and the Special Servicer may sell or
purchase, or permit the sale or purchase of, a Defaulted Loan or 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 Section 2.03(b) and
Section 9.01.

            (b) If any Loan becomes a Defaulted Loan and the Special Servicer
has determined in good faith that such Defaulted Loan will become subject to
foreclosure proceedings, the Special Servicer shall promptly so notify in
writing the Trustee and the Servicer. The Special Servicer (or the Servicer, if
the Special Servicer does not exercise its option, or the Directing
Certificateholder, if the Servicer does not exercise its option) may at its
option purchase such Defaulted Loan from the Trust Fund, at a price equal to the
Purchase Price. The Purchase Price for any Defaulted Loan purchased hereunder
shall be deposited into the Collection Account. Upon receipt by the Trustee of
an Officer's Certificate from the Special Servicer to the effect that such
deposit has been made, the Trustee shall notify the Servicer. The Servicer shall
then submit to the Custodian a Request for Release of the related Mortgage File
and the Custodian shall release such Mortgage File to the Special Servicer, the
Servicer or the Directing Certificateholder, as the case may be, and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, representation or warranty as shall be necessary to vest in
the Special Servicer, the Servicer or the Directing Certificateholder (in that
order), as the case may be, ownership of such Defaulted Loan.

            (c) The Special Servicer may offer to sell any Defaulted Loan not
otherwise purchased by the Special Servicer, the Servicer or the Directing
Certificateholder pursuant to subsection (b) above, if and when the Special
Servicer determines, consistent with the Servicing Standard, that such a sale
would produce a greater recovery on a present value basis than would liquidation
of the related Mortgaged Property. Such offering shall be made in a commercially
reasonable manner for a period of not less than 20 days or more than 90 days.
The Special Servicer shall accept the highest cash bid received from any Person
for such Defaulted Loan in an amount at least equal to the Purchase Price
therefor; provided, however, that in the absence of any such bid, the Special
Servicer shall accept the highest cash bid received from any Person that is
determined by the Special Servicer to be a fair price for such Defaulted Loan.
In the absence of any bid determined as provided below to be fair, the Special
Servicer shall proceed with respect to such Defaulted Loan in accordance with
Section 3.09.

            The Special Servicer shall use reasonable efforts to solicit bids
for each REO Property in such manner as will be reasonably likely to realize a
fair price within the time period provided for by Section 3.16(a). Such
solicitation shall be made in a commercially reasonable manner for a period of
not less than 90 days or more than 270 days. The Special Servicer shall accept
the highest cash bid received from any Person for such REO Property in an amount
at least equal to the Purchase Price therefor; provided, however, that in the
absence of any such bid, the Special Servicer shall accept the highest cash bid
received from any Person that is determined by the Special Servicer to be a fair
price for such REO Property. If the Special Servicer reasonably believes that it
will be unable to realize a fair price for any REO Property within the time
constraints imposed by Section 3.16(a), then the Special Servicer shall dispose
of such REO Property upon such terms and conditions as the Special Servicer
shall deem necessary and desirable to maximize the recovery thereon under the
circumstances and, in connection therewith, shall accept the highest outstanding
cash bid, regardless of from whom received. If the Special Servicer determines
with respect to any REO Property that the offers being made with respect thereto
are not in the best interests of the Certificateholders and that the end of the
period referred to in Section 3.16(a) with respect to such REO Property is
approaching, the Special Servicer shall seek an extension of such period in the
manner described in Section 3.16(a); provided, however, that the Special
Servicer shall use its best efforts, consistent with the Servicing Standard, to
sell any REO Property prior to three years prior to the Rated Final Distribution
Date.

            The Special Servicer shall give the Trustee and the Servicer not
less than three Business Days' prior written notice of its intention to sell any
Defaulted Loan or REO Property. No Interested Person shall be obligated to
submit a bid to purchase any Defaulted Loan or REO Property, and notwithstanding
anything to the contrary herein, neither the Trustee, in its individual
capacity, nor any of its Affiliates may bid for or purchase any Defaulted Loan
or any REO Property pursuant hereto.

            (d) Whether any cash bid constitutes a fair price for any Defaulted
Loan or REO Property, as the case may be, for purposes of Section 3.18(c), shall
be determined by the Special Servicer, if the highest bidder is a Person other
than the Special Servicer or an Affiliate thereof, and by the Trustee, if the
highest bidder is the Special Servicer or an Affiliate thereof. In determining
whether any bid received from the Special Servicer or an Affiliate thereof
represents a fair price for any Defaulted Loan or any REO Property, the Special
Servicer and the Trustee may conclusively rely on the opinion of an Appraiser or
other expert in real estate matters retained at the expense of the Trust Fund by
(i) the Trustee, if the highest bidder is the Special Servicer or an Affiliate
thereof or (ii) the Special Servicer, in any other case. In determining whether
any bid constitutes a fair price for any Defaulted Loan or any REO Property,
such Appraiser or other expert in real estate matters shall be instructed to
take into account, as applicable, among other factors, the period and amount of
any delinquency on the affected Defaulted 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). The Purchase Price for any Defaulted Loan or REO
Property shall in all cases be deemed a fair price.

            (e) Subject to subsections (a) through (d) above, the Special
Servicer shall act on behalf of the Trustee in negotiating and taking any other
action necessary or appropriate in connection with the sale of any Defaulted
Loan or REO Property, and the collection of all amounts payable in connection
therewith. Any sale of a Defaulted Loan or any REO Property shall be final and
without recourse to the Trustee or the Trust Fund, except, in the case of the
Trust Fund, as shall be customary in deeds of real property, and if such sale is
consummated in accordance with the terms of this Agreement, neither the Special
Servicer nor the Trustee shall have any liability to any Certificateholder with
respect to the purchase price therefor accepted by the Special Servicer or the
Trustee.

            Section 3.19      Additional  Obligations  of the Servicer and
Special Servicer; Inspections; Appraisals.

            (a) The Servicer (or, with respect to each Specially Serviced Loan
and REO Property and each Loan described in Section 3.19(d) below, the Special
Servicer) shall physically inspect or cause to be physically inspected (at its
own expense) each Mortgaged Property at such times and in such manner as are
consistent with the Servicing Standard, but in any event shall inspect each
Mortgaged Property (A) with a Stated Principal Balance equal to or greater than
$2,500,000 or which constitutes at least 2.0% of the then-current aggregate
principal balance of the Loans at least once every 12 months and (B) with a
Stated Principal Balance of less than $2,500,000 and which does not constitute
at least 2.0% of the then-current aggregate principal balance of the Loans, at
least every 24 months, in each case commencing in December 1999 (or at such
lesser frequency as each Rating Agency shall have confirmed in writing to the
Servicer, will not result a downgrade, qualification or withdrawal of the
then-current ratings assigned to any Class of the Certificates) and (C) if the
Loan (i) becomes a Specially Serviced Loan, (ii) has a Debt Service Coverage
Ratio of less than 1.0x or (iii) is delinquent for 60 days as soon as
practicable and thereafter at least once every 12 months for so long as such
condition exists. The Servicer or Special Servicer, as applicable, shall send
(i) to DCR, within 20 days of completion, each inspection report and (ii) to
Fitch and Moody's within 20 days of completion, each inspection report for
Significant Loans.

            (b) Notwithstanding the provisions of Section 3.19(a), with respect
to the Credit Lease Loans, the Servicer (or, if such Credit Lease Loan is a
Specially Serviced Loan, the Special Servicer) shall physically inspect or cause
to be physically inspected (at its own expense) each Mortgaged Property at least
once (i) every 36 months, if the related Credit Tenant or Guarantor has a
published rating of not less than "BBB," (ii) every 24 months if (A) the related
Credit Tenant or Guarantor has a published rating between "BB+" and "BB" or (B)
no published rating is publicly available for the related Credit Tenant and
(iii) every 12 months if (A) the related Credit Tenant or Guarantor has a
published rating of less than "BB" or (B) no published rating is publicly
available for the related Credit Tenant or Guarantor and such Credit Lease Loan
represents 2% or more of the then-current aggregate principal balance of the
Loans. In the event the published rating for any Credit Tenant or Guarantor is
downgraded by any Rating Agency by one or more rating increment (i.e., "AA" to
"A" or "BBB" to "B") and no inspection has been performed due to a ratings
downgrade in the preceding 12 months for the related Mortgaged Property, then in
each such instance, the Servicer shall cause all Mortgaged Properties leased to
such Credit Tenant to be inspected as soon as reasonably practicable.

            (c) With respect to each Loan (other than the L'Enfant
Participation) that allows the Special Servicer (on behalf of the Trust Fund) to
terminate, or cause the related Borrower to terminate, the related Manager upon
the occurrence of certain events specified in such Loan, the Special Servicer
shall enforce the Trustee's rights with respect to the Manager under the related
Loan and Management Agreement, provided, that, if such right accrues under the
related Loan or Management Agreement only because of the occurrence of the
related Anticipated Repayment Date, if any, the Special Servicer may in its sole
discretion, in accordance with the Servicing Standard, waive such right with
respect to such date. If the Special Servicer is entitled to terminate the
Manager, the Special Servicer shall promptly give notice to the Directing
Certificateholder and each Rating Agency. In accordance with the Servicing
Standard, the Special Servicer shall cause the Borrower to terminate the
Manager, and to recommend a Successor Manager (meeting the requirements set
forth below) only if the Special Servicer determines in its reasonable
discretion that such termination is not likely to result in successful
litigation against the Trust Fund by such Manager or the related Borrower, or
create a defense to the enforcement of remedies under such Loan.

            The Special Servicer shall effect such termination only if the
Special Servicer has (i) in the case of any Specially Serviced Loan that is a
Significant Loan, received a written confirmation from each of Fitch and Moody's
and (ii) in the case of any Specially Serviced Loan that represents 5% or more
of the then-current aggregate principal balance of the Loans, received a written
confirmation from each of the Rating Agencies, that the appointment of such
Successor Manager would not cause such Rating Agency to withdraw, downgrade or
qualify any of the then-current ratings on the Certificates. If a Manager is
otherwise terminated or resigns under the related Loan or Management Agreement
and the related Borrower does not appoint a Successor Manager, the Special
Servicer shall use its best efforts to retain a Successor Manager (or the
recommended Successor Manager, if any) on terms substantially similar to the
Management Agreement or, failing that, on terms as favorable to the Trust Fund
as can reasonably be obtained by the Special Servicer. For the purposes of this
paragraph, a "Successor Manager" shall be a professional management corporation
or business entity reasonably acceptable to the Special Servicer which (i)
manages, and is experienced in managing, other comparable commercial properties,
(ii) will not result in a downgrade, qualification or withdrawal of the
then-current ratings assigned to the Certificates by each Rating Agency, as
confirmed by such Rating Agency in writing (if required pursuant to the first
sentence of this paragraph), and (iii) otherwise satisfies any criteria set
forth in the Mortgage and related documents.

            (d) The Special Servicer shall be required to have received any
Appraisal required in connection with an Appraisal Reduction Event or perform an
internal valuation within 60 days after the occurrence of such Appraisal
Reduction Event (or the date of such Appraisal Reduction Event if the time
period between (i) the occurrence of the event that, with the passage of time,
would become such Appraisal Reduction Event and (ii) such Appraisal Reduction
Event exceeds 60 days). Upon receipt, the Special Servicer shall send a copy of
such Appraisal or internal valuation to the Certificate Owners of the
Controlling Class; provided, however, that as to each such Appraisal or internal
valuation, if beneficial ownership of the Controlling Class resides in more than
one Certificate Owner, the Special Servicer shall be responsible only for the
expense of providing the first such copy thereof and shall be entitled to
reimbursement from the Trust Fund for the expense of any additional copies so
provided. If neither a required Appraisal is received, nor an internal valuation
completed, by such date, or if, with respect to any Loan with a Stated Principal
Balance of $2,000,000 or less, the Special Servicer has elected not to obtain an
Appraisal or perform an internal valuation, the Appraisal Reduction for such
Loan shall be conclusively established to be 35% of the Stated Principal Balance
of such Loan as of the date of the related Appraisal Reduction Event. On the
first Determination Date occurring on or after the delivery of such Appraisal or
the completion of such internal valuation, and on each Determination Date
thereafter, the Special Servicer shall calculate and report to the Servicer, and
the Servicer shall report to the Certificate Administrator, the Appraisal
Reduction taking into account such Appraisal or internal valuation. The Servicer
shall verify the accuracy of the mathematical computation of the Appraisal
Reduction by the Special Servicer and that the amounts used therein are
consistent with the Servicer's records. Subject to this preceding sentence, the
Servicer may conclusively rely on any report by the Special Servicer of an
Appraisal Reduction.

            (e) With respect to each Loan as to which an Appraisal Reduction
Event has occurred (unless such Loan has become a Corrected Loan and has
remained current for twelve consecutive Monthly Payments for such purposes,
taking into account any amendment or modification of such Loan) and with respect
to which no other Appraisal Reduction Event has occurred and is continuing, the
Special Servicer shall, within 30 days of each annual anniversary of such
Appraisal Reduction Event, order an Appraisal (which may be an update of a prior
Appraisal), or with respect to any Loan with an outstanding principal balance
less than $2,000,000, perform an internal valuation or obtain an Appraisal
(which may be an update of a prior Appraisal), the cost of which shall be paid
by the Servicer as a Servicing Advance. Upon receipt, the Special Servicer shall
send a copy of such Appraisal to the Certificate Owners of the Controlling
Class; provided, however, that as to each such Appraisal, if beneficial
ownership of the Controlling Class resides in more than one Certificate Owner,
the Special Servicer shall be responsible only for the expense of providing the
first such copy thereof and shall be entitled to reimbursement from the Trust
Fund for the expense of any additional copies so provided. Such Appraisal or
internal valuation or percentage calculation of the Appraisal Reduction
described in the preceding paragraph, as the case may be, shall be used to
determine the amount of the Appraisal Reduction with respect to such Loan for
each Determination Date until the next Appraisal is required pursuant to this
Section 3.19(e), and such redetermined Appraisal Reduction shall replace the
prior Appraisal Reduction with respect to such Loan. Notwithstanding the
foregoing, the Special Servicer will not be required to obtain an Appraisal or
perform an internal valuation, as the case may be, with respect to a Loan which
is the subject of an Appraisal Reduction Event if the Special Servicer has
obtained an Appraisal with respect to the related Mortgaged Property within the
12-month period immediately prior to the occurrence of such Appraisal Reduction
Event. Instead, the Special Servicer may use such prior Appraisal in calculating
any Appraisal Reduction with respect to such Loan.

            With respect to each Loan as to which an Appraisal Reduction Event
has occurred and which has become a Corrected Loan and has remained current for
twelve consecutive Monthly Payments, taking into account any amendment or
modification of such Loan, and with respect to which no other Appraisal
Reduction Event has occurred and is continuing, the Special Servicer may within
30 days after the date of such twelfth Monthly Payment, order an Appraisal
(which may be an update of a prior Appraisal), or with respect to any Loan with
an outstanding principal balance less than $2,000,000, perform an internal
valuation or obtain an Appraisal (which may be an update of a prior Appraisal),
the cost of which shall be paid by the Servicer as a Servicing Advance. Based
upon such Appraisal or internal valuation, the Special Servicer shall
redetermine and report to the Trustee and the Servicer the amount of the
Appraisal Reduction with respect to such Loan and such redetermined Appraisal
Reduction shall replace the prior Appraisal Reduction with respect to such Loan.

            Section 3.20   Modifications, Waivers, Amendments and Consents.

            (a) Subject to the provisions of this Section 3.20, the Servicer and
the Special Servicer may, on behalf of the Trustee, agree to any modification,
waiver or amendment of any term of any Loan without the consent of the Trustee
or any Certificateholder.

               (i) For any Loan other than a Specially Serviced Loan and the
      L'Enfant Participation and subject to the rights of the Special Servicer
      set forth below, the Servicer shall be responsible subject to the other
      requirements of this Agreement with respect thereto, for any request by a
      Borrower for the consent of the mortgagee or a modification, waiver or
      amendment of any term thereof, provided that such consent or modification,
      waiver or amendment would not affect the amount or timing of any of the
      payment terms of such Loan, result in the release of the related Borrower
      from any material term thereunder, waive any rights thereunder with
      respect to any guarantor thereof or relate to the release or substitution
      of any material collateral for such Loan. To the extent consistent with
      the foregoing, the Servicer shall be responsible for the following:

                  (A) Approving any waiver affecting the timing of receipt of
            financial statements from any Borrower provided that such financial
            statements are delivered no less than quarterly and within 60 days
            of the end of the calendar quarter to which such financial
            statements relate;

                  (B) Approving routine leasing activity with respect to leases
            for less than the lesser of (a) 30,000 square feet and (b) 20% of
            the related Mortgaged Property;

                  (C) Approving annual budgets for the related Mortgaged
            Property, provided that no such budget (1) relates to a fiscal year
            in which an Anticipated Repayment Date occurs, (2) 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 (3) provides
            for the payment of any material expenses to any affiliate of the
            Borrower (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);

                  (D) Waiving any provision of a Loan requiring the receipt of a
            rating confirmation if such Loan is not a Significant Loan and the
            related provision of such Loan does not relate to a "due-on-sale" or
            "due-on-encumbrance" clause (which shall be subject to the terms of
            Section 3.08 hereof); and

                  (E) Subject to other restrictions herein regarding Principal
            Prepayments, waiving any provision of a Loan requiring a specified
            number of days notice prior to a Principal Prepayment.

               (ii)     Notwithstanding  the foregoing,  the Servicer shall
      not waive,  modify or amend the  provisions  of any Loan  unless such
      waiver,   modification   or   amendment   would  not   constitute   a
      "significant     modification"     under     Treasury     Regulations
      Section 1.860G-2(b).

               (iii) The Special Servicer shall be responsible for any request
      by a Borrower for the consent of the mortgagee and any modification,
      waiver or amendment of any term of any Loan for which the Servicer is not
      responsible, as provided above, or if such consent, request, modification,
      waiver or amendment relates to a Loan that is on the most recent Servicer
      Watch List, has a Debt Service Coverage Ratio (based on the most recently
      received financial statements and calculated on a trailing twelve month
      basis) less than the greater of 1.1x or 20% less than the Debt Service
      Coverage Ratio as of the Cut-off Date (unless such Loan is a credit lease
      loan) or with respect to which an event of default has occurred in the
      preceding 12 months.

            (b) All modifications, waivers or amendments of any Loan shall be
(i) in writing and (ii) effected in accordance with the Servicing Standard.

            (c) Neither the Servicer nor the Special Servicer, on behalf of the
Trustee, shall agree or consent to any modification, waiver or amendment of any
term of any Loan that is not a Specially Serviced Loan if such modification,
waiver or amendment 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 other
      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 Note prohibits Principal
      Prepayments;

               (iii) except as expressly contemplated by the related Mortgage or
      pursuant to Section 3.09(e), 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 Appraiser delivered at
      the expense of the related Mortgagor and upon which the Servicer and the
      Special Servicer, as applicable, may conclusively rely) of the property to
      be released; or

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

            (d) Notwithstanding Sections 3.20(b)(i), 3.20(c)(i) and 3.20(c)(ii),
but subject to Section 3.20(e), the Special Servicer may (i) reduce the amounts
owing under any Specially Serviced Loan by forgiving principal, accrued interest
and/or any Prepayment Premium or Yield Maintenance Charge, (ii) reduce the
amount of the Monthly Payment on any Specially Serviced Loan, including by way
of a reduction in the related Mortgage Rate, (iii) forbear in the enforcement of
any right granted under any Note or Mortgage relating to a Specially Serviced
Loan, (iv) waive Excess Interest if such waiver conforms to the Servicing
Standard and/or (v) accept a Principal Prepayment during any Lockout Period;
provided that the related Borrower is in default with respect to the Specially
Serviced Loan or, in the judgment of the Special Servicer, such default is
reasonably foreseeable.

            (e) Neither the Servicer nor the Special Servicer shall consent to,
make or permit (i) any modification with respect to any Loan that would change
the Mortgage Rate, reduce or increase the principal balance (except for
reductions resulting from actual payments of principal) or change the final
Maturity Date of such Loan unless both (A) the related Mortgagor is in default
with respect to the Loan or, in the judgment of the Special Servicer, such
default is reasonably foreseeable and (B) in the sole good faith judgment of the
Special Servicer and in accordance with the Servicing Standard, such
modification would increase the recovery on the Loan to Certificateholders on a
present value basis (the relevant discounting of amounts that will be
distributable to Certificateholders to be performed at the related Mortgage
Rate) or (ii) any modification, waiver or amendment of any term of any Loan that
would either (A) absent a default with respect to the Loan (or absent the
Special Servicer's determination that a default is reasonably foreseeable),
constitute a "significant modification" under Treasury Regulation Section
1.860G-2(b) or (B) cause either REMIC created hereunder 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.

            Notwithstanding the foregoing, the Special Servicer shall not extend
the date on which any Balloon Payment is scheduled to be due unless (x) the
Special Servicer has obtained an Appraisal of the related Mortgaged Property
(or, with respect to any related Loan with an outstanding principal balance less
than $2,000,000, has performed an internal valuation) in connection with such
extension, which Appraisal or internal valuation supports the determination of
the Special Servicer contemplated by clause (i)(B) of the immediately preceding
paragraph or (y) the related Loan has not been in default at any time during the
twelve-month period preceding the Maturity Date of such Loan, in which case the
Special Servicer, on one occasion only, may extend the date on which such
Balloon Payment is due to a date not more than 60 days after such Maturity Date.

            The determination of the Special Servicer contemplated by clause
(i)(B) of the first paragraph of this Section 3.20(e) shall be evidenced by an
Officer's Certificate to such effect delivered to the Trustee and the Servicer
and describing in reasonable detail the basis for the Special Servicer's
determination and the considerations of the Special Servicer forming the basis
of such determination (which shall include but shall not be limited to
information, to the extent available, such as related income and expense
statements, rent rolls, occupancy status and property inspections, and shall
include an Appraisal of the related Loan or Mortgaged Property, the cost of
which Appraisal shall be advanced by the Servicer as a Servicing Advance).

            (f) In no event shall the Special Servicer (i) extend the Maturity
Date of a Loan for more than three one-year extensions or beyond a date that is
three years prior to the Rated Final Distribution Date; (ii) extend the Maturity
Date of any Loan at an interest rate less than the lower of (a) the interest
rate in effect prior to such extension or (b) the then prevailing interest rate
for comparable loans, as determined by the Special Servicer by reference to
available indices for commercial mortgage lending; (iii) if the Loan is secured
by a ground lease, extend the Maturity Date of such Loan beyond a date which is
10 years prior to the expiration of the term of such ground lease; (iv) reduce
the Mortgage Rate to a rate below the lesser of (x) 7.64% per annum and (y) the
then prevailing interest rate for comparable loans, as determined by the Special
Servicer by reference to available indices for commercial mortgage lending; or
(v) defer interest due on any Loan in excess of 5% of the Stated Principal
Balance of such Loan.

            (g) Neither the Servicer nor the Special Servicer may permit or
modify a Loan to permit a voluntary Principal Prepayment of a Loan (other than a
Specially Serviced Loan) on any day other than its Due Date, (i) unless the
Servicer or Special Servicer also collects interest thereon through the Due Date
following the date of such Principal Prepayment, (ii) unless otherwise permitted
under the related Loan Documents or (iii) unless such Principal Prepayment would
not result in a Prepayment Interest Shortfall.

            (h) The Servicer and the Special 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 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, and (ii) any related costs and expenses incurred by it. In no event
shall the Special Servicer be entitled to payment for such fees or expenses
unless such payment is collected from the related Mortgagor.

            (i) The Special Servicer shall notify the Servicer, any related
Sub-Servicers, the Certificate Administrator and the Trustee, in writing, of any
modification, waiver or amendment of any term of any Loan (including fees
charged the Mortgagor) and the date thereof, and shall deliver to the Custodian
(with a copy to the Servicer) 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. The Servicer and Special Servicer shall notify the Rating
Agencies of any modification, waiver or amendment of any term of any Loan.
Copies of each agreement whereby any such modification, waiver or amendment of
any term of any Loan is effected shall be made available for review upon prior
request during normal business hours at the offices of the Servicer or Special
Servicer, as applicable, pursuant to Section 3.15 hereof.

            (j) With respect to each Borrower that has been established as a
"bankruptcy-remote entity," the Servicer shall not consent to (x) the amendment
by such Borrower of its organizational documents or (y) any action that would
violate any covenant of such Borrower relating to its status as a separate or
bankruptcy-remote entity. The Servicer shall promptly forward to the Special
Servicer any request received by the Servicer from a Borrower for any such
consent. If a Borrower has been established as a "bankruptcy-remote entity," the
Special Servicer shall not consent to (x) the amendment by such Borrower of its
organizational documents or (y) any action that would violate any covenant of
such Borrower relating to its status as a separate or bankruptcy-remote entity
unless (A) with respect to a Borrower under any Loan, the Special Servicer has
obtained written confirmation from DCR that such amendment or action would not
result in a downgrade or withdrawal of any rating on a Class of Certificates
rated by DCR and (B) with respect to a Borrower under any Significant Loan, the
Special Servicer has obtained written confirmation from Fitch and Moody's that
such amendment or action would not result in a downgrade, withdrawal or
qualification of any rating on a Class of Certificates rated by such Rating
Agency.

            Section 3.21      Transfer of Servicing  Between  Servicer and
Special Servicer; Record Keeping; Asset Status Report.

            (a) Upon determining that a Servicing Transfer Event has occurred
with respect to any Loan, the Servicer shall immediately give notice thereof to
the Special Servicer, the Certificate Administrator, the Custodian, the Trustee
and each Rating Agency, shall deliver copies of the related Mortgage File and
Credit File to the Special Servicer and the Directing Certificateholder and
shall use its reasonable best efforts to provide the Special Servicer with all
information, documents and records (including records stored electronically on
computer tapes, magnetic discs and the like) relating to such Loan that are in
the possession of the Servicer or available to the Servicer without undue burden
or expense, and reasonably requested by the Special Servicer to enable it to
assume its functions hereunder with respect thereto. The Servicer shall use its
reasonable best efforts to comply with the preceding sentence within five
Business Days of the occurrence of each related Servicing Transfer Event and in
any event shall continue to act as Servicer and administrator of such Loan until
the Special Servicer has commenced the servicing of such Loan. The Trustee shall
deliver to the Underwriters, the Initial Purchaser and each Holder of a
Certificate of the Controlling Class, a copy of the notice of such Servicing
Transfer Event provided by the Servicer to the Special Servicer pursuant to this
Section.

            Upon determining that a Specially Serviced Loan (other than an REO
Loan) has become a Corrected Loan (provided no additional Servicing Transfer
Event is foreseeable in the reasonable judgment of the Special Servicer) and
that no other Servicing Transfer Event is continuing with respect thereto, the
Special Servicer shall immediately give notice thereof and shall return the
related Mortgage File and Credit File to the Servicer and, upon giving such
notice and returning such Mortgage File and Credit File to the Servicer, the
Special Servicer's obligation to service such Corrected Loan shall terminate and
the obligations of the Servicer to service and administer such Loan shall
re-commence.

            (b) In servicing any Specially Serviced Loan, the Special Servicer
will provide to the Custodian, on behalf of the Trustee, 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 Servicer), and provide
the Servicer with copies of any additional related Loan information including
correspondence with the related Mortgagor.

            (c) No later than one Business Day after each Determination Date, by
4:00 p.m. New York City time, the Special Servicer shall deliver to the Servicer
a statement, both written and in computer readable format reasonably acceptable
to the Servicer and the Special Servicer (upon which the Servicer may
conclusively rely) describing, on a loan-by-loan and property-by-property basis,
(1) the information described in clause (vii) of Section 4.02(a) with respect to
each Specially Serviced Loan and the information described in clause (viii) of
Section 4.02(a) with respect to each REO Property, (2) the amount of all
payments, Insurance and Condemnation Proceeds and Liquidation Proceeds received
with respect to each Specially Serviced Loan during the related Due Period, and
the amount of all REO Revenues, Insurance and Condemnation Proceeds and
Liquidation Proceeds received with respect to each REO Property during the
related Due Period, (3) the amount, purpose and date of all Servicing Advances
made by the Servicer with respect to each Specially Serviced Loan and REO
Property during the related Due Period, (4) the information described in clauses
(v), (vii), (viii), (xi), (xvi) and (xvii) of Section 4.02(a) and (5) such
additional information or data relating to the Specially Serviced Loan and REO
Properties as the Servicer reasonably requests to enable it to perform its
responsibilities under this Agreement which is in the Special Servicer's
possession or is reasonably obtainable by the Special Servicer.

            (d) Notwithstanding the provisions of the preceding clause (c), the
Servicer shall maintain ongoing payment records with respect to each of the
Specially Serviced Loan and REO Properties and shall provide the Special
Servicer with any information in its possession required by the Special Servicer
to perform its duties under this Agreement.

            (e) No later than 30 days after a Servicing Transfer Event for a
Loan, the Special Servicer shall deliver to each Rating Agency, the Servicer and
the Directing Certificateholder a report (the "Asset Status Report") with
respect to such 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 Loan;

               (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 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 Loan; and

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

            If within ten Business Days of receiving an Asset Status Report, the
Directing Certificateholder 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 or the terms of the
applicable Loan Documents. If the Directing Certificateholder disapproves such
Asset Status Report, the Special Servicer shall revise such Asset Status Report
and deliver to the Directing Certificateholder, the Rating Agencies and the
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(e) until the earlier of (a) the failure of
the Directing Certificateholder to disapprove such revised Asset Status Report
in writing within 10 Business Days of receiving such revised Asset Status
Report; (b) a determination by the Special Servicer as set forth below or (c)
the passage of 60 days from the date of preparation of the first Asset Status
Report. 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 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 and it has made a
reasonable effort to contact the Directing Certificateholder and (ii) in any
case, shall determine whether any affirmative disapproval by the Directing
Certificateholder described in this paragraph is not in the best interest of all
the Certificateholders pursuant to the Servicing Standard.

            Upon making the determination described in subclause (ii) of the
immediately preceding paragraph (but in no event more than 60 days after the
date of preparation of the Asset Status Report), the Special Servicer shall
notify the Trustee and Certificate Administrator of such rejection and deliver
to the Trustee and Certificate Administrator a proposed notice to
Certificateholders which shall include a copy of the Asset Status Report, in
electronic format, and the Certificate Administrator shall make such notice
available on the Website to all Privileged Persons. If the majority of
Certificateholders, as determined by Voting Rights, fail, within 5 days of the
Certificate Administrator's sending or making available 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, the
Special Servicer shall revise such Asset Status Report as described above. The
Certificate Administrator shall be entitled to reimbursement from the Trust Fund
for the reasonable expenses of providing such notices.

            The Special Servicer shall have the authority to meet with the
Mortgagor for any Specially Serviced Loan and take such actions consistent with
the Servicing Standard 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 Directing Certificateholder shall (a) require or
cause the Special Servicer to violate the terms of a Specially Serviced 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 each REMIC created hereunder, or (b) result in the
imposition of a "prohibited transaction" or "prohibited contribution" tax under
the REMIC Provisions, or (c) expose the Servicer, the Special Servicer, the
Depositor, either of the Mortgage Loan Sellers, the Trust Fund, the Certificate
Administrator, the Trustee or their Affiliates, officers, directors, employees
or agents to any claim, suit or liability, or (d) materially expand the scope of
the Special Servicer's or the Servicer's responsibilities under this Agreement.

            (f) Upon receiving notice of (i) the filing of a case under any
federal or state bankruptcy, insolvency or similar law or the commencing of any
insolvency, readjustment of debt, marshaling of assets and liabilities or
similar proceedings with respect to a Loan or the related Mortgagor, (ii) the
existence of a material non-payment default or (iii) the request by a Mortgagor
for the amendment or modification of a Loan, the Servicer shall immediately give
notice thereof, and shall deliver copies of the related Mortgage File and Credit
File to the Special Servicer and shall use its reasonable best efforts to
provide the Special Servicer with all information relating to the Loan and
reasonably requested by the Special Servicer to enable it to negotiate with the
related Mortgagor and prepare for any such proceedings. The Servicer shall use
its reasonable best efforts to comply with the preceding sentence within 5
Business Days of the occurrence of each such event, and upon receiving such
documents and information, the Special Servicer shall use its reasonable best
efforts to cause the related Mortgagor to cure any default and/or remedy any
such event, work out or modify the Loan consistent with the terms of this
Agreement, and/or prepare for such proceedings. Notwithstanding the foregoing,
the occurrence of any of the above-referenced events shall not in and of itself
be considered a Servicing Transfer Event.

            Section 3.22      Sub-Servicing Agreements.

            (a) The Servicer and the Special Servicer may enter into
Sub-Servicing Agreements to provide for the performance by third parties of any
or all of its respective obligations under Articles III and IV hereof; provided
that the Sub-Servicing Agreement: (i) is consistent with this Agreement in all
material respects and requires the Sub-Servicer to comply with all of the
applicable conditions of this Agreement; (ii) except with respect to the Primary
Servicing Agreements, provides that if the Servicer or the Special Servicer
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 shall thereupon assume or may elect not to assume all of the rights
and, except to the extent they arose prior to the date of assumption,
obligations of the Servicer or Special Servicer, as applicable under such
agreement, or, alternatively, may act in accordance with Section 7.02 hereof
under the circumstances described therein; (iii) provides that the Trustee for
the benefit of the Certificateholders shall be a third-party beneficiary under
such Sub-Servicing Agreement, but that (except to the extent the Trustee or its
designee assumes the obligations of the Servicer or the Special Servicer, as
applicable, thereunder as contemplated by the immediately preceding clause (ii))
none of the Trust Fund, the Trustee, the Certificate Administrator, any
successor Servicer, Special Servicer or any Certificateholder shall have any
duties under such Sub-Servicing Agreement or any liabilities arising therefrom;
(iv) except with respect to the Primary Servicing Agreements, permits any
purchaser of a Loan or the Trustee pursuant to this Agreement to terminate such
Sub-Servicing Agreement with respect to such purchased Loan at its option and
without penalty; (v) does not permit the Sub-Servicer any direct rights of
indemnification that may be satisfied out of assets of the Trust Fund; (vi) does
not permit the Sub-Servicer to foreclose on the related Mortgaged Property or
consent to the modification of any Loan without the prior consent of the
Servicer or Special Servicer, as applicable; (vii) provides that the
Sub-Servicer shall act in accordance with the Servicing Standard; (viii)
provides that in the event of an act or failure to act by the Sub-Servicer that
causes the Servicer to be in default of its obligations under this Agreement,
the Sub-Servicer shall be in default of its obligations under such Sub-Servicing
Agreement; and (ix) if such Sub-Servicing Agreement is a Primary Servicing
Agreement, provides that upon termination of the Trust Fund, the owner of the
Loans shall, with respect to those Loans serviced by each Primary Servicer enter
into a servicing agreement with such Primary Servicer in the form of the related
"Prior Servicing Agreement" (as defined in the Primary Servicing Agreement) or
shall pay such Primary Servicer the termination fee that would be payable
thereunder. Any successor Servicer or Special Servicer hereunder, upon becoming
successor Servicer or Special Servicer, as applicable, shall have the right to
be assigned and shall have the right to assume any Sub-Servicing Agreements from
the predecessor Servicer or Special Servicer, as applicable. Upon a termination
of the Servicer pursuant to this Agreement, the successor to the Servicer (other
than the Trustee or its designee) shall automatically succeed to the rights and
obligations of the prior Servicer under the Primary Servicing Agreement, subject
to the termination rights set forth therein, it being understood that any such
succession by the Trustee or its designee shall not be automatic but shall be in
the discretion of the Trustee or such designee.

            In addition, each Sub-Servicing Agreement entered into by the
Servicer may provide that the obligations of the Sub-Servicer thereunder shall
terminate with respect to any Loan serviced thereunder at the time such Loan
becomes a Specially Serviced Loan. The Servicer shall deliver to the Trustee
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. For purposes of this Agreement, the Servicer shall
be deemed to have received any payment when a Sub-Servicer retained by it
receives such payment. The Servicer shall notify the Special Servicer, the
Trustee and the Depositor in writing promptly of the appointment by it of any
Sub-Servicer. The Special Servicer shall notify the Servicer, 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) As part of its servicing activities hereunder, the Servicer or
the Special Servicer, as applicable, 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 each
Sub-Servicer under the related Sub-Servicing Agreement. 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 Servicer would require were it the owner
of the Loans. The Servicer or the Special Servicer, as applicable, shall have
the right to remove a Sub-Servicer retained by it in accordance with the terms
of the related Sub-Servicing Agreement upon the Events of Default and other
termination events specified in the related Sub-Servicing Agreement.

Special Servicer, as applicable, at its expense, shall deliver to the assuming
party all documents and records relating to such Sub-Servicing Agreement and the

each of the Servicer and the Special Servicer represents and warrants that it
shall remain obligated and liable to the Trustee and the Certificateholders for
the performance of its 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 it alone were servicing and administering the Loans for which
it is responsible, and the Servicer, or the Special Servicer, as applicable,
shall pay the fees of any Sub-Servicer thereunder from its own funds or, with
respect to the Primary Servicers, shall permit each to retain the Primary
Servicing Fees from amounts collected by such Primary Servicer. In no event
shall the Trust Fund bear any termination fee required to be paid to any
Sub-Servicer as a result of such Sub-Servicer's termination under any
Sub-Servicing Agreement.

            (f) The Trustee shall furnish to any Sub-Servicer any limited powers
of attorney and other documents necessary or appropriate to enable such
Sub-Servicer to carry out its servicing and administrative duties under any
Sub-Servicing Agreement; provided, however, that the Trustee shall not be held
liable for any negligence or misuse of, any such power of attorney by a
Sub-Servicer, and shall be indemnified by the Sub-Servicer, with respect
thereto.

            (g) Except with respect to the Primary Servicing Agreements, each
Sub-Servicing Agreement shall provide that, in the event the Trustee or any
other Person becomes a successor Servicer or the Special Servicer, as

applicable, shall have the right to terminate such Sub-Servicing Agreement at
its option and without a fee.

            (h) Promptly (but in no event later than five Business Days) after
the execution of any Sub-Servicing Agreement, the Servicer shall forward a copy
of such Sub-Servicing Agreement to the Special Servicer, and the Special
Servicer shall forward a copy of such Sub-Servicing Agreement to the Trustee.
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.

      breach of, any material agreement or other instrument to which it is a
      party or which is applicable to it or any of its assets, or result in the

      insolvency, reorganization, moratorium and other laws affecting the
      enforcement of creditors' rights generally, and general principles of
      equity, regardless of whether such enforcement is considered in a
      proceeding in equity or at law;

      any order or decree of any court, or any order, regulation or demand of
      any federal, state, municipal or governmental agency, which violations are
      likely to have consequences that would materially and adversely affect the
      condition (financial or other) or operations of the Servicer or its
      properties or are likely to have consequences that would materially and
      adversely affect its ability to perform its duties and obligations
      hereunder;

               (v) No litigation is pending or, to the best of the Servicer's
      knowledge, threatened against the Servicer which would prohibit the
      Servicer from entering into this Agreement or, in the Servicer's good

      affect either the ability of the Servicer to perform its obligations under
      this Agreement;

               (vi) The Servicer will examine each Sub-Servicing Agreement and
      will be familiar with the terms thereof. Any Sub-Servicing Agreements will

      Agreement, except for any consent, approval, authorization or order which
      has been obtained or will be obtained prior to the actual performance by
      the Servicer of its obligations under this Agreement, and which, if not
      obtained would have a materially adverse effect on the ability of the
      Servicer to perform its obligations hereunder;

               (viii) The Servicer has full power and authority to enter into
      and consummate all transactions contemplated by this Agreement, has duly

      has duly executed and delivered this Agreement;

               (ix) The Servicer has examined each Sub-Servicing Agreement to
      which it is a party, and shall examine each Sub-Servicing Agreement to
      which it intends to become a party, and in each such case, the terms of
      such Sub-Servicing Agreements are not, or, in the case of any
      Sub-Servicing Agreement to be entered into by the Servicer at a future
      date, will not be, materially inconsistent with the terms of this

      the Servicer that has responsibilities concerning the servicing and
      administration of Loans is covered by errors and omissions insurance in
      the amounts and with the coverage required by Section 3.07(c). Neither the
      Servicer nor any officer, director, employee, consultant or advisor of the
      Servicer that is involved in the servicing or administration of Loans has

of the operation or management of, or the compiling, reporting or generation of
data required by this Agreement will not contain any deficiency (x) in the
ability of such software or hardware to identify correctly or perform
calculations or other processing with respect to dates after the Closing Date or
(y) that would cause such software or hardware to be fit no longer for the
purpose for which it was intended by reason of changing the date from 1999 to
2000. Without limiting any rights or remedies of the Trust Fund, the
Certificateholders or any other party hereto for a breach under any other
Section of this Agreement that may arise out of the failure of the Servicer to

      Servicer;

               (vi) No litigation is pending or, to the best of the Special

            Series 1999-C1 from purchasing or selling such Certificates in
            circumstances where the other party to the transaction is not also
            in possession of such information. You also acknowledge and agree
            that such information is being provided to you for the purposes of,
            and such information may be used only in connection with, evaluation
            by you or another Certificateholder, Certificate Owner or
            prospective purchaser of such Certificates or beneficial interest
            therein.

            The Servicer and the Special Servicer may, at its discretion, make
available by electronic media and bulletin board service certain information and
may make available by electronic media or bulletin board service (in addition to
making such information available as provided herein) any reports or information
required by this Agreement that the Servicer or the Special Servicer is required
to provide to any of the Rating Agencies, the Depositor and anyone the Depositor
reasonably designates.

            Section 3.28      Lock-Box Accounts and Servicing Accounts.

            (a) The Servicer shall administer each Lock-Box Account, Cash
Collateral Account and Servicing Account in accordance with the related Mortgage
or Loan Agreement, Cash Collateral Account Agreement or Lock-Box Agreement, if
any.

            (b) For any Loan that provides that a Lock-Box Account will be
established upon the occurrence of certain events specified in the related Loan
Documents, the Servicer (or, with respect to any Specially Serviced Loan, the
Special Servicer) shall establish on behalf of the Trust such Lock-Box Account
upon the occurrence of such events unless the Servicer (or the Special Servicer,
as applicable) determines, in accordance with the Servicing Standard, that such
Lock-Box Account should not be established. Notwithstanding the foregoing, the
Servicer (or the Special Servicer, as applicable) shall establish a Lock-Box
Account for each ARD Loan no later than its Anticipated Repayment Date.

            (c) With respect to each Loan requiring the establishment of a
Lock-Box Account, the Servicer, upon receipt of the annual financial statements
of each Mortgagor, shall compare the gross revenue for the related Mortgaged
Property, as set forth in such financial statements, with the history of the
related Mortgagor's deposits into such Lock-Box Account and shall report any
discrepancies over 10% to the Special Servicer.

            (d) Within 60 days after an escrow account has been established on
behalf of a Mortgagor pursuant to the terms of the related Mortgage, the
Servicer shall notify the financial institution maintaining such account of the
Trustee's security interest in the funds in such account in those jurisdictions
where required in order to perfect or maintain perfection of the related
security interest.

            Section 3.29      Interest Reserve Account.

            (a) The Servicer shall establish, on or before the Closing Date, and
maintain the Interest Reserve Account on behalf of the Lower-Tier REMIC. As of
the Closing Date, the Interest Reserve Account shall be located at the offices
of the Servicer, provided such account is an Eligible Account. The Servicer
shall give notice to the Trustee, the Certificate Administrator, the Special
Servicer and the Depositor of the location of the Interest Reserve Account and,
prior to any change thereof, any new location of the Interest Reserve Account.
On each Servicer Remittance Date ending in any February and on any Servicer
Remittance Date ending in any January which occurs in a year which is not a leap
year, the Servicer shall deposit into the Interest Reserve Account in respect of
each Actual/360 Loan an amount withheld from the related Monthly Payment or
Advance equal to one day's interest on the Stated Principal Balance of such
Actual/360 Loan as of the Distribution Date occurring in the month preceding the
month in which such Servicer Remittance Date occurs at the related Net Mortgage
Rate, to the extent a full Monthly Payment or P&I Advance is made in respect
thereof (all amounts so deposited in any consecutive January and February (or,
in the case of a leap year, in any February), "Withheld Amounts").

            (b) On each Servicer Remittance Date occurring in March, the
Servicer shall withdraw from the Interest Reserve Account an amount equal to the
Withheld Amounts from the preceding December and January Interest Accrual
Periods, if any, and deposit such amount (excluding any net investment income
thereon) into the Lower-Tier Distribution Account.

            Section 3.30      Limitations  on  and  Authorizations  of the
Servicer and Special Servicer with Respect to Certain Loans.

            (a) Prior to taking any action with respect to a Loan secured by any
Mortgaged Properties located in a "one-action" state, the Special Servicer shall
consult with legal counsel, the fees and expenses of which shall be a Servicing
Advance.

            (b) With respect to any Loan which permits the related Borrower,
with the consent or grant of a waiver by the mortgagee, to incur additional
indebtedness or to amend or modify the related Borrower's organizational
documents, the Special Servicer may consent (subject, without limitation, to
Section 3.20(e) hereof) to either such action, or grant a waiver with respect
thereto, only if the Special Servicer determines that such consent or grant of
waiver is likely to result in a greater recovery on a present value basis
(discounted at the related Mortgage Rate) than the withholding of such consent
or grant of waiver, and the Special Servicer first obtains written confirmation
from each Rating Agency that such consent or grant of waiver would not, in and
of itself, result in a downgrade, qualification or withdrawal of any of the
then-current ratings assigned to the Certificates. The Servicer shall not be
entitled or required to consent to, or grant a waiver with respect to, either
action.

            (c) With respect to any ARD Loan, so long as no event of default
beyond applicable notice and grace periods has occurred and is continuing, the
Servicer and the Special Servicer shall not take any enforcement action with
respect to the payment of Excess Interest or principal in excess of the
principal component of the constant Monthly Payment, other than requests for
collection, until the date on which principal and all accrued interest (other
than Excess Interest) has been paid in full. Nothing in this paragraph shall
limit the obligation of the Servicer and the Special Servicer to establish a
Lock-Box Account pursuant to Section 3.28.

            (d) With respect to the Loans that (i) require earthquake insurance,
or (ii) (A) at the date of origination were secured by Mortgaged Properties on
which the related Borrower maintained earthquake insurance and (B) have
provisions which enable the Servicer to continue to require the related Borrower
to maintain earthquake insurance, the Servicer shall require the related
Borrower to maintain such insurance in the amount, in the case of clause (i),
required by the Loan and in the amount, in the case of this clause (ii),
maintained at origination, in each case, to the extent such amounts are
available at commercially reasonable rates. Any determination by the Servicer
that such insurance is not available at commercially reasonable rates with
respect to a Loan for which any related Mortgaged Property has a "Probable
Maximum Loss," bounded on the basis of 50 years, in excess of 20% shall be
subject to confirmation by Fitch that such determination not to purchase such
insurance will not result in a downgrade, qualification or withdrawal of the
then-current ratings assigned to the Certificates rated by Fitch.

            (e) (i) Within 10 days after the Closing Date, the Servicer shall
notify the Residual Value Insurer that (A) both the Servicer and the Special
Servicer shall be sent notices under the Residual Value Policy and (B) the
Trustee, on behalf of the Trust, shall be the loss payee under the Residual
Value Policy. The Servicer and the Special Servicer shall abide by the terms and
conditions precedent to payment of claims under the Residual Value Policy and
shall take all such action as may be required to comply with the terms and
provisions of such policy in order to maintain, in full force and effect, such
policy. If the Servicer has written notice or actual knowledge of any event (an
"Insured Event") giving rise to a claim under any Residual Value Policy, the
Servicer shall notify the Special Servicer thereof as soon as reasonably
practicable, but in no event later than three Business Days after learning of
such event. The Special Servicer shall comply with all conditions to coverage,
including (i) preparing and filing a "proof of loss" form containing all
required information with the Residual Value Insurer within five Business Days
and in any event no later than the "termination date" (as defined in the related
policy) after receiving notice of any Insured Event under the related policy,
(ii) providing any other notices required under the Residual Value Policy in a
timely fashion and (iii) taking any other actions which will maximize recovery
under such the Residual Value Policy. The Special Servicer shall diligently
process any claims under the Residual Value Policy in accordance with the
Servicing Standard. The Special Servicer shall give notice to the Servicer of
any claim made under any Residual Value Policy and of any Residual Value Policy
Termination Event of which the Servicer does not already have notice.

                  (ii) If the Servicer receives notice of any abatement,
rescission, cancellation, termination, contest, legal process, arbitration or
disavowal of liability with respect to any Residual Value Policy (a "Residual
Value Policy Termination Event"), the Servicer shall, within three Business Days
after receipt of such notice, notify the Special Servicer, the Trustee and the
Rating Agencies of such Residual Value Policy Termination Event in writing. Upon
receipt of such notice, the Special Servicer shall, notwithstanding that the
servicing of the related Loan may not have been transferred to the Special
Servicer in accordance with Section 3.21 hereof, address such Residual Value
Policy Termination Event in accordance with the Servicing Standard. Any legal
fees incurred in connection with a resolution of a Residual Value Policy
Termination Event shall be paid by the Servicer as a Servicing Advance and shall
be reimbursable to it from the Borrower or other responsible party, and if not
recoverable, then such legal fees shall be reimbursable as a Nonrecoverable
Advance.

            (f) The Servicer and Special Servicer shall review and be familiar
with the terms and conditions relating to enforcing claims and shall monitor the
dates by which any claim or action is required to be taken (including delivering
any notices to the Residual Value Insurer and performing any actions required
under the Residual Value Insurance Policy) under each insurance policy to
realize the full value of such policy for the benefit of Certificateholders.

            (g) The Special Servicer shall not consent to a change of franchise
affiliation with respect to any hotel property that in whole or in part
constitutes the Mortgaged Property securing a Loan unless it obtains written
confirmation from each Rating Agency that such change of franchise affiliation
would not, in and of itself, result in a downgrade, qualification or withdrawal
of the then-current ratings on any Class of Certificates. The Special Servicer
shall not be required to obtain such written consent from DCR if the
then-current principal balance of such Loan is less than 2% of the then-current
aggregate principal balance of the Loans.

            (h) With respect to any Loan that permits the related Borrower to
incur subordinate indebtedness secured by the related Mortgaged Property, the
Special Servicer shall enforce the rights of the lender, if any, under the Loan
Documents to require such borrower to enter into a subordination and standstill
agreement with the lender of such subordinate indebtedness.

            (i) The Servicer or Special Servicer, as applicable, shall provide
notice to DCR and prepare and provide DCR with any internal memorandum prepared
by the Servicer or Special Servicer outlining its analysis and recommendation in
accordance with the Servicing Standard (together with copies of all relevant
documentation) for all consents, approvals or authorizations granted by the
Servicer or Special Servicer for transfers, assumptions, encumbrances,
additional debt, material amendments, grants of easement or encumbrance,
franchise affiliation changes and property manager changes concerning Mortgage
Loans, including consents, approvals or authorizations granted pursuant to
Sections 3.08(a), (b) and (i), 3.19(c), 3.20(a)(i) and 3.30(g).

            (j) Within 10 days after the Closing Date, the Servicer shall notify
the Environmental Policy Insurer that (A) both the Servicer and the Special
Servicer shall be sent notices under the Environmental Policy and (B) the
Trustee, on behalf of the Trust, shall be the loss payee under the Environmental
Policy. The Servicer and the Special Servicer shall abide by the terms and
conditions precedent to payment of claims under the Environmental Policy and
shall take all such action as may be required to comply with the terms and
provisions of such policy in order to maintain, in full force and effect, such
policy.

            (k) The Depositor shall, as to each Loan which is secured by the
interest of the related Mortgagor under a ground lease, at its own expense,
promptly (and in any event within 45 days of the Closing Date) notify the
related ground lessor of the transfer of such Loan to the Trust 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 Trustee and the
Custodian.

            Section 3.31      REMIC Administration.

            (a) The Certificate Administrator shall make or cause to be made
elections to treat each of the Lower-Tier REMIC and the Upper-Tier REMIC as a
REMIC under the Code and if necessary, under State Tax Laws. Each such election
will be made on Form 1066 or other appropriate federal tax or information return
or any appropriate state return for the taxable year ending on the last day of
the calendar year in which the Certificates are issued, which in each case shall
be signed by the Trustee. The Certificate Administrator shall designate the
"regular interests" and the "residual interests," within the meaning of the
REMIC Provisions, in each REMIC as set forth in the Preliminary Statement
hereto. To the extent the affairs of the Trust Fund are within their control,
the Servicer, the Special Servicer and the Certificate Administrator shall not
permit the creation of any "interests" (within the meaning of Section 860G of
the Code) in either REMIC created hereunder other than the Uncertificated
Lower-Tier Interests (excluding the Class LR Certificates) and the Certificates
(other than the Class V-1 and Class V-2 Certificates).

            (b) The Closing Date is hereby designated as the "Startup Day" for
each REMIC within the meaning of Section 860G(a)(9) of the Code.

            (c) The Holder of the largest Percentage Interest of the Class LR
Certificates is hereby designated, and by the acceptance of its Class LR
Certificate agrees to act, as Tax Matters Person for the Lower-Tier REMIC. Any
Holder of a Class LR or Class R Certificate must at all times hold a 13.73%
Percentage Interest therein. The Holder of the Class R Certificates is hereby
designated, and by the acceptance of its Class R Certificate agrees to act, as
Tax Matters Person for the Upper-Tier REMIC. The Certificate Administrator is
hereby designated as the agent of the Tax Matters Person of each of the
Lower-Tier REMIC and the Upper-Tier REMIC and shall perform all the functions
thereof, and the Holders of the Class LR and Class R Certificates, by their
acceptance of such Certificates, agree to such designation.

            (d) The Certificate Administrator shall prepare or cause to be
prepared all of the Tax Returns that it reasonably determines are required with
respect to each REMIC created hereunder. Promptly upon receipt of any tax return
from the Certificate Administrator, the Trustee shall sign and return such tax
return to the Certificate Administrator. The Certificate Administrator shall
file such Tax Returns in a timely manner. The expenses of preparing such returns
shall be borne by the Certificate Administrator without any right of
reimbursement therefor.

            (e) The Certificate Administrator shall provide (i) upon request by
any Transferor of a Class LR or Class R Certificate, such information to such
Transferor and the IRS as is (x) reasonably necessary for the application of any
tax relating to the transfer of a Class LR or Class R Certificate to any Person
who is not a Disqualified Organization or (y) otherwise required to be provided
by Treasury Regulation Section 1.860E-2 (and in the time and manner required to
be provided to such person under such Regulation), (ii) to the
Certificateholders such information or reports as are required by the Code, the
REMIC Provisions or State Tax Laws including reports relating to interest,
original issue discount and market discount or premium (using the Prepayment
Assumption) and (iii) to the Internal Revenue Service the name, title, address
and telephone number of the person who will serve as the representative of each
of the REMICs.

            (f) The Certificate Administrator shall take such actions and shall
cause each REMIC created hereunder to take such actions as are reasonably within
the Certificate Administrator's control and the scope of its duties more
specifically set forth herein as shall be necessary to maintain the status
thereof as REMICs under the REMIC Provisions (and the Servicer, the Trustee and
Special Servicer shall assist the Certificate Administrator, to the extent
reasonably requested by the Certificate Administrator to do so). None of the
Servicer, the Special Servicer, the Trustee or the Certificate Administrator
shall knowingly or intentionally take any action, cause either REMIC created
hereunder to take any action or fail to take (or fail to cause to be taken) any
action reasonably within its control and the scope of duties more specifically
set forth herein, that, under the REMIC Provisions, if taken or not taken, as
the case may be, could (i) cause either REMIC created hereunder to fail to
qualify as a REMIC or (ii) result in the imposition of a tax under the REMIC
Provisions upon either REMIC created hereunder (including but not limited to the
tax on prohibited transactions as defined in Section 860F(a)(2) of the Code and
the tax on contributions to a REMIC set forth in Section 860G(d) of the Code)
(either such event, an "Adverse REMIC Event") unless such party receives an
Opinion of Counsel (at the expense of the party seeking to take such action or,
if such party fails to pay such expense, and such party determines that taking
such action is in the best interest of the Trust Fund and the
Certificateholders, at the expense of the Trust Fund, but in no event at the
expense of such party) to the effect that the contemplated action will not, with
respect to either of the REMICs created hereunder, cause either REMIC to fail to
qualify as a REMIC or, unless such party (which is acceptable to the Certificate
Administrator) determines that the monetary expense to both REMICs is not
material and in its sole discretion to indemnify (to the extent reasonably
acceptable to the Certificate Administrator) the Trust Fund against such tax,
result in the imposition of such a tax. Wherever in this Agreement a
contemplated action may not be taken because the timing of such action might
result in the imposition of a tax on the Trust Fund, or may be taken only
pursuant to an Opinion of Counsel that such action would impose a tax on the
Trust Fund, such action may nonetheless be taken so long as (x) the indemnity
given in the preceding sentence with respect to any taxes that might be imposed
on the Trust Fund has been given and (y) all other preconditions to the taking
of such action have been satisfied. The Certificate Administrator shall not take
any action (whether or not authorized hereunder) as to which the Servicer has
advised it in writing that it has received 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 the Trust Fund or its
assets, or causing the Trust Fund to take any action, which is not expressly
permitted under the terms of this Agreement, each of the parties hereto will
consult with the Certificate Administrator or its designee, in writing, with
respect to whether such action could cause an Adverse REMIC Event to occur with
respect to either REMIC created hereunder, and such party shall not take any
such action, or cause either such REMIC to take any such action, as to which the
Certificate Administrator has advised it in writing that an Adverse REMIC Event
could occur. The Certificate 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. At all times as may be
required by the Code, the Certificate Administrator will to the extent within
its control and the scope of its duties as specifically set forth herein,
maintain substantially all of the assets of the Trust Fund as "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.

            (g) In the event that any tax is imposed on "prohibited
transactions" of either REMIC created hereunder as defined in Section 860F(a)(2)
of the Code, on "net income from foreclosure property" of either REMIC as
defined in Section 860G(c) of the Code, or any other tax is imposed by the Code
or any applicable provisions of state or local tax laws, such tax shall be
charged (i) to a Servicer, if such tax arises out of or results from a breach by
such Servicer of any of its obligations under this Agreement and such breach is
not caused by the breach of another party, (ii) to the Certificate
Administrator, if such tax arises out of or results from a breach by the
Certificate Administrator of any of its obligations under this Agreement and
such breach is not caused by the breach of another party and (iii) otherwise,
against amounts on deposit in the Collection Account, and on the Distribution
Date(s) following such reimbursement the aggregate of such taxes shall be
allocated in reduction of the Optimal Interest Distribution Amount on each Class
entitled thereto in the same manner as if such taxes constituted an Uncovered
Prepayment Interest Shortfall Amount.

            (h) The Certificate Administrator shall, for federal income tax
purposes, maintain books and records with respect to each REMIC on a calendar
year and on an accrual basis or as otherwise may be required by the REMIC
Provisions.

            (i) Following the Startup Day, none of the Servicer, the Certificate
Administrator or the Trustee shall accept any contributions of assets to either
REMIC created hereunder unless the Servicer, the Certificate Administrator and
the Trustee shall have received an Opinion of Counsel (at the expense of the
party seeking to make such contribution) to the effect that the inclusion of
such assets in either REMIC created hereunder will not cause such REMIC to fail
to qualify as a REMIC at any time that any Certificates are outstanding or
subject either REMIC created hereunder to any tax under the REMIC Provisions or
other applicable provisions of federal, state and local law or ordinances.

            (j) None of the Servicer, the Special Servicer, the Certificate
Administrator or the Trustee shall enter into any arrangement by which either
REMIC created hereunder will receive a fee or other compensation for services
nor, to the extent reasonably within their control, permit either such REMIC to
receive an 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.

            (k) For the purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
Regulations, the "latest possible maturity date" by which the Certificate
Balance of each Class of Regular Certificates created hereunder would be reduced
to zero is the Rated Final Distribution Date, including for this purpose the
Class O Certificates.

            (l) Within 30 days after the Closing Date, the Certificate
Administrator shall prepare and file with the Internal Revenue Service Form
8811, "Information Return for Real Estate Mortgage Investment Conduits (REMIC)
and Issuers of Collateralized Debt Obligations" (or applicable successor form)
for the Upper-Tier REMIC created hereunder.

            (m) None of the Trustee, the Certificate Administrator, the Servicer
or the Special Servicer shall sell or dispose of or substitute for any of the
Loans (except in connection with (i) the default, imminent default or
foreclosure of a Loan, including but not limited to, the acquisition or sale of
a Mortgaged Property acquired by deed in lieu of foreclosure, (ii) the
bankruptcy of either REMIC created hereunder, (iii) the termination of either
REMIC created hereunder pursuant to Article X of this Agreement or (iv) a
purchase of Loans pursuant to Article II or Section 3.18 of this Agreement) nor
acquire any assets for either REMIC created hereunder, nor sell or dispose of
any investments in the Collection Account for gain, nor accept any contributions
to either REMIC created hereunder after the Closing Date, unless it has received
an Opinion of Counsel that such sale or disposition will not affect adversely
the status of either REMIC as a REMIC or cause either REMIC created hereunder to
be subject to a tax on "prohibited transactions" or "contributions" pursuant to
the REMIC Provisions.

            (n) The Depositor shall provide or cause to be provided to the
Certificate Administrator, within ten (10) days after the Closing Date, and
thereafter on an ongoing basis, all information or data requested by the
Certificate Administrator that the Certificate Administrator reasonably
determines to be relevant for tax purposes as to the valuations and Issue Prices
of the Certificates, including without limitation, the price, yield, original
issue discount, market discount or premium and projected cash flow of the
Certificates. In addition, the Servicer, the Special Servicer, the Trustee and
the Depositor shall provide on a timely basis to the Certificate Administrator
or its designee such information with respect to the Trust Fund as is in its
possession and reasonably requested by the Certificate Administrator to enable
it to perform its obligations under this Article. The Certificate Administrator
shall be entitled to rely conclusively upon all such information so provided to
it without recalculation or other investigation.

            (o) The Certificate Administrator and the Trustee shall be entitled
to reasonable compensation and to the reimbursement of its reasonable expenses
incurred in the performance of its duties under this Section 3.31 as may be
agreed upon by the Certificate Administrator and the Depositor; provided,
however, that the Certificate Administrator and the Trustee shall pay out of its
own funds, without any right of reimbursement, any and all ordinary expenses of
the Trust Fund incurred in the performance of its duties under this Article but
shall be reimbursed, except as otherwise expressly provided for herein, by the
Trust Fund for any of its extraordinary expenses, including any taxes or
tax-related payments, any expenses involved in any tax examination, audit or
proceeding, and the expense of any tax-related Opinion of Counsel or other
professional advice requested by the Certificate Administrator for the benefit
or protection of the Certificateholders.

            (p) The Certificate Administrator shall treat the rights of the
Certificateholders to receive Yield Protection Payments as assets that the
Certificate Administrator holds separate and apart from the Certificateholders'
respective portions of the Certificates treated as REMIC regular interests, and
shall treat the Certificateholders as owning their respective portions of the
Certificates treated as REMIC regular interests and their respective portions of
the rights to receive Yield Protection Payments represented by the respective
Certificates. Notwithstanding any other provision of this Agreement, the rights
of the Certificateholders to receive Yield Protection Payments will not be
treated as assets of either REMIC created pursuant to this Agreement.

            Section 3.32      Servicer  and  Special   Servicer  May  Own
Certificates.

            (a) The Servicer and any agent of the Servicer in its individual or
any other capacity may become the owner or pledgee of Certificates with the same
rights it would have if it were not the Servicer or such agent, except with
respect to Voting Rights, as set forth in the definition of "Certificateholder."

            (b) The Special Servicer and any agent of the Special Servicer in
its individual or any other capacity may become the owner or pledgee of
Certificates with the same rights it would have if it were not the Special
Servicer or such agent, except with respect to Voting Rights, as set forth in
the definition of "Certificateholder."

                         PAYMENTS TO CERTIFICATEHOLDERS

            Section 4.01      Distributions.

            (a) On each Distribution Date prior to the date on which the
Certificate Balance of the last outstanding Class of Subordinate Certificates
has been reduced to zero, to the extent of the Available Distribution Amount for
such Distribution Date, the Certificate Administrator shall transfer or be
deemed to transfer such amounts from the Lower-Tier Distribution Account to the
Upper-Tier Distribution Account in the amounts and priorities set forth in
Section 4.01(b) with respect to each Class of Uncertificated Lower-Tier
Interests, and immediately thereafter, shall make distributions thereof from the
Upper-Tier Distribution 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 from the Available
Distribution Amount:

               (i) concurrently, to the Class A-1, Class A-2 and Class A-X
      Certificates, pro rata, up to the Optimal Interest Distribution Amounts
      for each such Class for such Distribution Date;

               (ii) to the Class A-1, and Class A-2 Certificates, in reduction
      of the Certificate Balances thereof, an amount up to the Principal
      Distribution Amount for such Distribution Date, in the following order of
      priority:

            first,  to the Class A-1  Certificates,  until the  Certificate
      Balance thereof has been reduced to zero; and

            second,  to the Class A-2  Certificates,  until the Certificate
      Balance thereof has been reduced to zero;

               (iii) to the Class A-1, and Class A-2 Certificates, pro rata
      (based on the aggregate unreimbursed Collateral Support Deficit previously
      allocated to each such Class), until all amounts of such Collateral
      Support Deficit previously allocated to such Classes, but not previously
      reimbursed, have been reimbursed in full;

               (iv) to the Class B Certificates, in respect of interest, up to
      the Optimal Interest Distribution Amount for such Class for such
      Distribution Date;

               (v) to the Class B Certificates, in reduction of the Certificate
      Balance thereof, an amount up to the Remaining Principal Distribution
      Amount for such Distribution Date until such Certificate Balance has been
      reduced to zero;

               (vi) to the Class B Certificates, until all amounts of Collateral
      Support Deficit previously allocated to the Class B Certificates, but not

               (xli) to the Class O Certificates, in reduction of the

      and

               (xliii) to the Class R and Class LR Certificates, the amount, if
      any, remaining in the Upper-Tier REMIC and the Lower-Tier REMIC,
      respectively.

            (b) On each Distribution Date, each Uncertificated Lower-Tier
Interest shall receive distributions from the Lower-Tier Distribution Account in
respect of principal or reimbursement of Collateral Support Deficit in an amount
equal to the amount of principal or reimbursement of Collateral Support Deficit
distributable to such Uncertificated Lower-Tier Interest's respective Class of
Related Certificates as provided in Sections 4.01(a) and (c). During each
Interest Accrual Period, each Uncertificated Lower -Tier Interest shall accrue
interest in an amount equal to the principal balance of each such Uncertificated
Lower-Tier Interest multiplied by the Weighted Average Net Mortgage Rate.

            On each Distribution Date, each Uncertificated Lower-Tier Interest
shall receive distributions in respect of interest in an amount equal to the sum
of (i) the amount of interest that will actually be distributed in respect of
such Uncertificated Lower-Tier Interest's Related Certificate and (ii) the
amount of interest that will actually be distributed in respect of such
Uncertificated Lower-Tier Interest's corresponding Related Component. In all
events, the amount accrued in respect of each Uncertificated Lower-Tier Interest
less the amount actually distributed in respect of such Uncertificated
Lower-Tier Interest shall equal the sum of (i) the Interest Shortfall Amount
allocated to such Uncertificated Lower-Tier Interest's Related Certificates,
(ii) the Interest Shortfall Amount allocated to the Related Component and
attributable to such Uncertificated Lower-Tier Interest and (iii) any
Certificate Deferred Interest allocated to such Uncertificated Lower-Tier
Interest. Any amounts remaining in the Lower-Tier REMIC after payment to the
Uncertificated Lower-Tier Interest and payment of expenses of the Trust Fund
shall be distributed to the Class LR Certificate[s]. Such amounts distributed to
the Uncertificated Lower-Tier Interests in respect of principal, interest and
reduction of Collateral Support Deficit with respect to any Distribution Date
are referred to herein collectively as the "Lower-Tier Distribution Amount" and
shall be made by the Certificate Administrator by depositing such Lower-Tier
Distribution Amount in the Upper-Tier Distribution Account.

            As of any date, payments of principal in respect of the Loans and
the Collateral Support Deficit shall be allocated to the Uncertificated
Lower-Tier Interests such that the sum of the principal balance after
application of any Collateral Support Deficit of each Uncertificated Lower-Tier
Interest and the cumulative amount of Collateral Support Deficit allocated to
such Class of Uncertificated Lower-Tier Interests equals the sum of the
Certificate Balance of the Related Certificates after the application of any
Collateral Support Deficit with respect thereto and the cumulative amount of
Collateral Support Deficit allocated to such Class of Related Certificates. The
initial principal balance of each Uncertificated Lower-Tier Interest equals the
respective Original Lower-Tier Principal Amount. The interest rate with respect
to each Uncertificated Lower-Tier Interest will be the Weighted Average Net
Mortgage Rate.

            Interest Shortfall Amounts allocated to the Class A-X Certificates
shall be attributed first, to the most senior Uncertificated Lower-Tier Interest
outstanding to the extent of its Related Component and, then, to the next most
senior Uncertificated Lower-Tier Interest to the extent of its Related
Component, until all such amounts are allocated. Any amounts so allocated shall
have the same seniority as interest payments due on the Class A-X Certificates.
Interest shall be treated as accrued rather than paid on an Uncertificated
Lower-Tier Interest to the extent that its Related Class of Certificates is
treated as earning Certificate Deferred Interest, and any such interest shall be
added to the principal balance of such Uncertificated Lower-Tier Interest so as
to cause its principal balance to equal the principal balance of its Related
Class of Certificates. Any amount that remains in the Lower-Tier Distribution
Account on each Distribution Date after distribution of the Lower-Tier
Distribution Amount shall be distributed to the Holders of the Class LR
Certificates (but only to the extent of the Available Distribution Amount for
such Distribution Date remaining in the Lower-Tier Distribution Account, if
any). Prepayment Interest Shortfalls shall be allocated to each Class of
Uncertificated Lower-Tier Interests on the basis of their respective interest
entitlements.

            (c) Notwithstanding the foregoing, on each Distribution Date
occurring on or after the date on which the Certificate Balance of the last
outstanding Class of Subordinate Certificates has been reduced to zero, the
Certificate Administrator shall apply amounts on deposit in the Upper-Tier
Distribution Account in the following order of priority: (i) concurrently, to
the Class A-1, Class A-2 and Class A-X Certificates, pro rata, in respect of the
Optimal Interest Amount allocable to each such Class; (ii) to the Class A-1, and
Class A-2 Certificates, pro rata in reduction of the Certificate Balances
thereof, until the Certificate Balance of each such Class has been reduced to
zero; and (iii) to the Class A-1, and Class A-2 Certificates, pro rata (based on
the aggregate unreimbursed Collateral Support Deficit previously allocated to
such Class) until all amounts of such Collateral Support Deficit previously
allocated to such Classes but not previously reimbursed have been reimbursed in
full.

            (d) On each Servicer Remittance Date, the Servicer shall deposit all
Prepayment Premiums and Yield Maintenance Charges in the Lower-Tier Distribution
Account for payment to the Uncertificated Lower-Tier Interests. On each
Distribution Date, the Certificate Administrator shall withdraw from the
Lower-Tier Distribution Account an aggregate amount equal to all Prepayment
Premiums and Yield Maintenance Charges actually collected on the Loans or any
REO Loans during the related Due Period and shall distribute such amount to the
Lower-Tier Interests, pro rata in proportion to their outstanding principal
balances.

            (e) On each Distribution Date, the Certificate Administrator shall
withdraw any amounts on deposit in the Upper-Tier Distribution Account that
represent Prepayment Premiums and Yield Maintenance Charges actually collected
on Loans or REO Loans during the related Due Period and remitted in respect of
the Uncertificated Lower-Tier Interests pursuant to Section 4.01(d), and shall
distribute such amounts as follows:

               (i) Prepayment Premiums shall be distributed to the Class A-1,
      Class A-2, Class B, Class C, Class D, Class E and Class F Certificates, in
      an amount equal to the product of (a) a fraction whose numerator is the
      amount distributed as principal to such Class on such Distribution Date,
      and whose denominator is the total amount distributed as principal to the
      Class A-1, Class A-2, Class B, Class C, Class D, Class E, Class F, Class
      G, Class H, Class J, Class K, Class L, Class M, Class N and Class O
      Certificates on such Distribution Date, (b) 25% and (c) the total amount
      of Prepayment Premiums collected during the related Due Period. Any
      Prepayment Premiums collected during the related Due Period and remaining
      after such distributions shall be distributed to the Holders of the Class
      A-X Certificates; and

               (ii) Yield Maintenance Charges shall be distributed to the Class
      A-1, Class A-2, Class B, Class C, Class D, Class E and Class F
      Certificates, in an amount equal to the product of (a) a fraction whose
      numerator is the amount distributed as principal to such Class on such
      Distribution Date, and whose denominator is the total amount distributed
      as principal to the Class A-1, Class A-2, Class B, Class C, Class D, Class
      E, Class F, Class G, Class H, Class J, Class K, Class L, Class M, Class N
      and Class O Certificates on such Distribution Date, (b) the Base Interest
      Fraction for the related Principal Prepayment and such Class of
      Certificates and (c) the aggregate amount of Yield Maintenance Charges
      collected on such Principal Prepayment during the related Due Period. Any
      Yield Maintenance Charges collected during the related Due Period
      remaining after such distributions shall be distributed to the Holders of
      the Class A-X Certificates.

            Following the reduction of the Certificate Balances of the Class
A-1, Class A-2, Class B, Class C, Class D, Class E and Class F Certificates to
zero, the Certificate Administrator shall distribute to the Class A-X
Certificates all Yield Maintenance Charges and Prepayment Premiums actually
received during the related Due Period with respect to the Loans and remitted in
respect of Uncertificated Lower-Tier Interests pursuant to Section 4.01(d).

            (f) On any applicable Distribution Date, (i) any Excess Interest
collected in respect of the CSFB Loans for such Distribution Date shall be
distributed from the Excess Interest Distribution Account to the Class V-1
Certificates and (ii) any Excess Interest collected in respect of the MS Loans
for such Distribution Date shall be distributed from the Excess Interest
Distribution Account to the Class V-2 Certificates.

            (g) 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 specifically provided in Sections 4.01(h), 4.01(i) and 9.01, 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 Certificate Administrator with written
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) and is the registered owner of
Certificates with an aggregate initial Certificate Balance (or in the case of
the Class A-X Certificates, a Notional Balance) of at least $5,000,000 or, in
the case of the Class V-1, Class V-2 Certificates, a Percentage Interest equal
to 25% or, in the case of the Class R or Class LR Certificates, a Percentage
Interest equal to 13.73%, 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 without regard to any possible
future reimbursement of Collateral Support Deficit previously allocated to such
Certificate) shall be made in like manner, but only upon presentation and
surrender of such Certificate at the offices of the Certificate Administrator or
such other location specified in the notice to Certificateholders of such final
distribution.

            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 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 Certificate Owners that it represents. None of the Trustee, the
Certificate Administrator, the Depositor, the Servicer, the Special Servicer,
the Underwriters or the Initial Purchaser shall have any responsibility therefor
except as otherwise provided by this Agreement or applicable law.

            (h) Except as otherwise provided in Section 9.01, whenever the
Certificate Administrator expects that the final distribution with respect to
any Class of Certificates (determined without regard to any possible future
reimbursement of any amount of Collateral Support Deficit previously allocated
to such Class of Certificates) will be made on the next Distribution Date, the
Certificate Administrator shall, no later than two Business Days following the
related P&I Advance Determination Date, post a notice on the Website to the
effect that no interest shall accrue on such Certificates from and after such
Distribution Date.

            Any funds not distributed to any Holder or Holders of Definitive
Certificates of any 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 Definitive Certificates
as to which notice has been given pursuant to Section 4.01(h) shall not have
been surrendered for cancellation within six months after the time specified in
such notice, the Certificate Administrator shall mail a second notice to the
remaining non-tendering Definitive 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 Definitive
Certificates shall not have been surrendered for cancellation, the Certificate
Administrator, directly or through an agent, shall take such steps to contact
the remaining non-tendering Definitive 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 Definitive
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 Definitive
Certificateholder on any amount held in trust hereunder by the Certificate
Administrator as a result of such Definitive Certificateholder's failure to
surrender its Certificate(s) for final payment thereof in accordance with
Section 4.01(h).

            (i) Distributions in reimbursement of Collateral Support Deficit
previously allocated to the Regular Certificates shall be made in the amounts
and manner specified in Section 4.01(a) to the Holders of the respective Class
otherwise entitled to distributions of interest and principal on such Class on
the relevant Distribution Date; provided, however, that all distributions in
reimbursement of Collateral Support Deficit previously allocated to a Class of
Certificates which has since been retired shall be to the prior Holders that
surrendered the Certificates of such Class upon retirement thereof and shall be
made by check mailed to the address of each such prior Holder last shown in the
Certificate Register. Notice of any such distribution to a prior Holder shall be
made in accordance with Section 10.05 at such last address. The amount of the
distribution to each such prior Holder shall be based upon the aggregate
Percentage Interest evidenced by the Certificates surrendered thereby. If the
check mailed to any such prior Holder is returned uncashed, then the amount
thereof shall be set aside and held uninvested in trust for the benefit of such
prior Holder, and the Certificate Administrator shall attempt to contact such
prior Holder in the manner contemplated by Section 4.01(i) as if such Holder had
failed to surrender its Certificates.

            (j) Shortfalls in the Available Distribution Amount on any
Distribution Date resulting from Prepayment Interest Shortfalls not covered by
compensation to the Servicer pursuant to the last paragraph of Section 3.11(a)
shall be allocated to each Class of Regular Certificates, pro rata, based on the
Accrued Certificate Interest Amount distributable to each such Class on such
Distribution Date. The amount by which the servicing compensation is to be
reduced in connection with Prepayment Interest Shortfalls pursuant to the last
paragraph of Section 3.11(a) shall be deposited by the Servicer into the
Collection Account on or prior to the Servicer Remittance Date.

            Shortfalls in the Available Distribution Amount resulting from
unanticipated Trust Fund indemnification expenses incurred pursuant to Section
6.03 and Section 8.05 shall be allocated to each Class of Regular Certificates,
pro rata, based on the Accrued Certificate Interest Amount distributable to each
such Class. Unanticipated indemnification expenses which are applied to each
Class of Certificates shall be allocated to the Uncertificated Lower-Tier
Interests corresponding to such Classes.

            (k) On each Distribution Date on which the Holders of a Class or
Classes of Regular Certificates receive a distribution of Additional Collateral
Prepayment Amounts (which distribution shall be deemed made after application of
that portion of the Principal Distribution Amount other than such Additional
Collateral Prepayment Amounts), (i) the Regular Yield Protection Payment Amount
for such Distribution Date shall be distributed to such Class or Classes pro
rata in accordance with the portion of such Additional Collateral Prepayment
Amount that is allocated to each such Class and (ii) the Class A-X Yield
Protection Payment Amount for such Distribution Date shall be distributed to the
Holders of the Class A-X Certificates, in each case from the Yield Protection
Payment Account.

Servicer and the other reports prepared by the Servicer and Special Servicer
relating to such Distribution Date, and only to the extent such information is

Class LR Certificate a copy of the reports forwarded to the other
Certificateholders on such Distribution Date and a statement setting forth the

            (b) On or prior to each Distribution Date, based on information

service which can be accessed by calling (301) 815-6610.

            In addition, on or prior to each Distribution Date, based on

Servicer and delivered to the Certificate Administrator in accordance herewith,
the Certificate Administrator shall make available via the Website or, upon
request, forward, solely to Privileged Persons, (i) the Restricted Servicer
Reports and (ii) the Property File.

            The Certificate Administrator shall also make available to any
Privileged Person the Investor Q&A Forum. The "Investor Q&A Forum" shall be a
service offered by the Certificate Administrator, as facilitator, through the
Website and shall permit users to (i) submit questions to the Certificate
Administrator via e-mail, which questions relate to the Loans or the Mortgaged
Properties ("Investor Inquiries"), and (ii) view Investor Inquiries previously
submitted and the answers thereto. Upon receipt of a submission from a user, the
Certificate Administrator shall forward the Investor Inquiry to either the
Servicer (if such Investor Inquiry relates to a Loan that is not a Specially
Serviced Loan) or the Special Servicer (if such Investor Inquiry relates to a
Specially Serviced Loan) within 4 Business Hours of receipt thereof. With
respect to any Investor Inquiry forwarded to the Servicer, within one Business
Day of receipt of such Investor Inquiry from the Certificate Administrator, the
Servicer shall determine whether answering such Investor Inquiry would not be in
the best interests of the Trust and/or the Certificateholders. If the Servicer
determines that answering such Investor Inquiry would be in the best interests
of the Trust and/or the Certificateholders, the Servicer shall forward a copy of
such Investor Inquiry to the Special Servicer and notify the Special Servicer of
its determination. The Special Servicer shall notify the Servicer within two
Business Days of receipt of such determination if it agrees or disagrees with
the Servicer's determination. If the Special Servicer disagrees with the
Servicer's determination, the Servicer shall not answer such Investor Inquiry
and shall promptly notify the Certificate Administrator, which shall notify the
Person who submitted such Investor Inquiry. If the Special Servicer fails to
respond within such two Business Day period, the Special Servicer shall be
deemed to agree with the Servicer's determination. Within one Business Day
following the Special Servicer's agreement or deemed agreement with the
Servicer's determination (with respect to Investor Inquiries that relate to
Loans that are not Specially Serviced Loans) or within two Business Days
following receipt of an Investor Inquiry from the Certificate Administrator by
the Special Servicer (with respect to Specially Serviced Loans), the Servicer or
the Special Servicer, respectively, shall reply to the Investor Inquiry with (A)
the answer to such Investor Inquiry, or (B) if such Investor Inquiry cannot
reasonably be answered within such one Business Day, such longer period of time
as is necessary to answer such Investor Inquiry, provided such longer period of
time shall be commercially reasonable (which it shall then be required to adhere
to). Upon receipt of any such answer from the Servicer or the Special Servicer,
the Certificate Administrator shall post (within 4 Business Hours of receipt of
such answer) such Investor Inquiry and the related answer (or a statement
concerning the additional time necessary until such answer shall be made
available) to the Website. If the Servicer or the Special Servicer determines,
in its respective sole discretion, that answering any Investor Inquiry would not
be in the best interests of the Trust and/or the Certificateholders, it shall
not be required to answer such Investor Inquiry, and shall promptly notify the
Certificate Administrator, who shall notify the Person who submitted such
Investor Inquiry.

            The 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 Servicer or the
Special Servicer under this Agreement.

            In addition, the Certificate Administrator shall make available to
any Privileged Person, via the Website, the Special Events Bulletin. The
"Special Events Bulletin" shall list all of the events for which the Certificate
Administrator receives notice from the Servicer (with respect to Loans that are
not Specially Serviced Loans) or the Special Servicer (with respect to Loans
that are Specially Serviced Loans or with respect to Special Events described in
(vi) and (vii) below) that such event occurred and constitutes a Special Event,
together with the date such Special Event has occurred. The following shall

      knowledge otherwise obtained, regarding a prepayment, material casualty or

      part of the related Loan (provided that a request by a Borrower or other
      Person for a quotation of the amount necessary to satisfy all obligations
      with respect to a Loan shall not, in and of itself, be deemed to be such
      notice);

               (ii) the status of capital improvement (i.e., work has commenced,
      work is underway or work is completed) having a cost of $1,000,000 or more

      the related reserves;

               (iii) the results of any property inspection of which the

      environmental condition with respect to any Mortgaged Property;

               (iv) any notice from a Borrower, or any knowledge otherwise
      obtained, regarding any judgment against such Borrower or involving any
      Mortgaged Property which the Servicer deems to be a Servicing Transfer
      Event or which the Special Servicer reasonably believes is likely to have
      an adverse effect on such Mortgaged Property or the ability of such
      Borrower to pay the amounts due under the related Loan;

               (v) any notice received from a Borrower, Manager or tenant of a
      Mortgaged Property, or any knowledge otherwise obtained, regarding the
      material default of such tenant under the terms of its lease or early
      termination by either any tenant that (A) leases more than 20% of the
      gross leasable area and (B) the absence of such tenant would result in a
      DSCR less than 1.25x or the Borrower of such lease, the bankruptcy of such
      tenant or its direct or indirect parent, or the loss of a license or
      permit of such tenant relating to any Mortgaged Property;

               (vi) any amendment, modification or waiver of a material
      provision of a Loan of which the Special Servicer has knowledge, provided
      that the Special Servicer need not disclose the nature of any asset
      strategy or proposed modifications in connection with a work-out or
      resolution of a Specially Serviced Loan;

               (vii) any change in the ownership of a Borrower or Mortgaged
      Property or request for consent to an assumption of a Loan;

               (viii) any material lien being recorded on a Mortgaged Property
      if such recordation is a Servicing Transfer Event;

               (x) such other information as the Servicer or Special Servicer

      market any anchor space (which, for such purposes, shall be space
      comprising more than 15% of the gross leasable area), new developments,
      net absorption and market vacancy rates, rents and expenses; and

               (xi) any event designated as such by the Depositor.

            The Certificate Administrator shall list the occurrence of any
Special Event on the Website promptly upon receipt of notice from the Servicer
or Special Servicer, but no later than the next scheduled Distribution Date.

            The Certificate Administrator shall not be liable for the
dissemination of information in accordance with this Section 4.02(b). The
Certificate Administrator makes no representations or warranties as to the
accuracy or completeness of any report, document, questions, answer, special
event, or other information made available on the Website and assumes no
responsibility therefor. In addition, the Certificate Administrator may disclaim
responsibility for any information distributed by the Certificate Administrator
for which it is not the original source.

            In connection with providing access to the Website, the Certificate
Administrator may require registration and the acceptance of a disclaimer.

            (c) The Trustee shall make available at its offices, during normal
business hours, upon not less than ten Business Days' prior written notice, for
review by any Certificateholder, any prospective investor in a Certificate, the
Depositor, the Certificate Administrator, the Servicer, the Special Servicer,
any Rating Agency and any other Person to whom the Depositor believes such
disclosure is appropriate, originals or copies of documents relating to the
Loans and any related REO Properties to the extent in its possession, including,
without limitation, the following items (except to the extent prohibited by
applicable law or by the terms of any of the Mortgage Documents): (i) this
Agreement and any amendments thereto; (ii) all Statements to Certificateholders
delivered to the Certificateholders since the Closing Date; (iii) all annual
Officers' Certificates and all accountants' reports delivered by the Servicer or
Special Servicer to the Trustee since the Closing Date regarding compliance with
the relevant agreements; (iv) any and all Officers' Certificates and other
evidence delivered to or by the Certificate Administrator to support the
Servicer's or the Trustee's, as the case may be, determination that any Advance,
if made, would be a Nonrecoverable Advance; and (v) any other materials not
otherwise required to be provided to a requesting Certificateholder pursuant to
this Agreement, in situations where such requesting Certificateholder declined
to enter into a confidentiality agreement with the Servicer. The Custodian shall
make available at its offices, during normal business hours, upon not less than
ten Business Days' prior written notice, for review by any Certificateholder,
any prospective investor in a Certificate, the Depositor, the Trustee, the
Certificate Administrator, the Servicer, the Special Servicer, any Rating Agency
and any other Person to whom the Depositor believes such disclosure is
appropriate, originals or copies of any and all modifications, waivers and
amendments of the terms of a Loan entered into by the Servicer and/or the
Special Servicer and delivered to the Certificate Administrator. The Servicer
shall cooperate with the Trustee to make any of the above-mentioned items
available to any Certificateholder upon its request and payment by it of
reasonable costs. Copies of any and all of the foregoing items will be available
from the Trustee or the Custodian, as applicable, upon written request therefor.
The Trustee or the Custodian, as applicable, will be permitted to require
payment by the requesting party (other than a Rating Agency) of a sum sufficient
to cover the reasonable costs and expenses of making such information available
and providing any copies thereof. The Trustee's and Custodian's obligation under
this Section 4.02(c) to make available any document is subject to the Trustee's
and Custodian's receipt of such document.

            (d) Notwithstanding the foregoing provisions of this Article 4.02,
the Certificate Administrator shall not be required to provide the full
reporting provided for in Sections 4.02(b) and (c) unless and until the Servicer
provides its related reporting to the Certificate Administrator in CMSA format.

            (e) The Servicer and the Special Servicer shall not be required to
conduct research or obtain information that is not available to the Servicer or
the Special Servicer, respectively, in the ordinary course of its servicing
activities hereunder. In addition, the Servicer and the Special Servicer shall
not be required to (i) answer commercially unreasonable questions, (ii) answer
questions relating to matters that extend beyond the scope of its duties as
Servicer or Special Servicer, respectively, (iii) answer questions that would,
in the Servicer's or the Special Servicer's sole discretion, require the
Servicer or the Special Servicer to devote an unreasonable amount of time or
resources to answer, (iv) disclose information that would violate the terms of
any of the Loan Documents or initiate contact with Mortgagors or third parties
except in connection with the ordinary course of its servicing duties hereunder
or (v) express opinions or make recommendations under this Section 4.02(b) (it
being understood that the Servicer and the Special Servicer may limit their
responses to factual matters). The provision of information hereunder by the
Servicer and the Special Servicer shall be subject to Section 3.27(d) and
Section 3.27(f), as applicable.

            Section 4.03   P&I  Advances; Yield Protection Payment Advances.

            (a) On or before 3:00 p.m. New York City time on each P&I Advance
Date, the Servicer shall (i) deposit into the Distribution Accounts from its own
funds an amount equal to the aggregate amount of P&I Advances, if any, to be
made in respect of the related Distribution Date, (ii) apply amounts held in the
Collection Account that are not required to be part of the Available
Distribution Amount for such Distribution Date or (iii) make P&I Advances in the
form of any combination of (i) and (ii) aggregating the total amount of P&I
Advances to be made. Any amounts held in the Collection Account not required to
be a part of the Available Distribution Amount for such Distribution Date and so
used to make P&I Advances shall be appropriately reflected in the Servicer's
records and replaced by the Servicer by deposit in the Collection Account on or
before the next succeeding P&I Advance Determination Date (to the extent not
previously replaced through the deposit of Late Collections of the delinquent
principal and/or interest in respect of which such P&I Advances were made). The
Servicer shall notify the Trustee and the Certificate Administrator by a
certificate of the Servicing Officer of (i) the aggregate amount of P&I Advances
for a Distribution Date and (ii) the amount of any Nonrecoverable P&I Advances
for such Distribution Date, on or before the Servicer Remittance Date.

            (b) Subject to Section 4.03(c) and (e) below, the aggregate amount
of P&I Advances to be made by the Servicer with respect to any Distribution Date
shall equal the aggregate of: (i) all Monthly Payments (in each case, net of
related Primary Servicing Fees, Servicing Fees and Workout Fees, if any), other
than Balloon Payments, that were due during any related Due Period and
delinquent as of the close of business on the Business Day preceding the related
P&I Advance Date (or not advanced by any Sub-Servicer on behalf of the
Servicer); and (ii) with respect to each Loan as to which the related Balloon
Payment was due during or prior to the related Due Period and was delinquent as
of the end of the related Due Period (including any REO Loan as to which the
Balloon Payment would have been past due), an amount equal to the Assumed
Scheduled Payment therefor. All P&I Advances for any Loan that have been
modified shall be calculated on the basis of their terms as modified. Subject to
subsection (c) below, the obligation of the Servicer to make such P&I Advances
is mandatory and, with respect to any Loan or REO Loan, shall continue until the
Distribution Date on which the proceeds, if any, received in connection with a
Liquidation Event with respect thereto are to be distributed.

            (c) Notwithstanding anything herein to the contrary, neither the
Servicer nor the Trustee shall be required to make a P&I Advance, if the
Servicer or the Trustee determines, in accordance with the definition thereof,
that any such P&I Advance would be a Nonrecoverable Advance. The Trustee may
conclusively rely on any determination of nonrecoverability by the Servicer. The
Special Servicer shall not be required to make P&I Advances under this
Agreement. On the fourth Business Day before each Distribution Date, the Special
Servicer shall report to the 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 Loan or REO Loan is a Nonrecoverable P&I Advance. The
Servicer shall be entitled to conclusively rely on (but shall not be bound by)
such determination.

            (d) In connection with the recovery of any P&I Advance out of the
Collection Account pursuant to Section 3.05(a), the Servicer shall be entitled
to pay itself or the Trustee, as the case may be, out of any amounts then on
deposit in the Collection Account, interest at the Reimbursement Rate in effect
from time to time, accrued on the amount of such P&I Advance from the date made
to but not including the date of reimbursement. The Servicer shall reimburse
itself or the Trustee, as the case may be, for any outstanding P&I Advance as
soon as practicably possible after funds available for such purpose are
deposited in the Collection Account.

            (e) Notwithstanding the foregoing, (i) neither the Servicer nor the
Trustee shall be required or permitted to make an advance for Penalty Charges,
Prepayment Premiums, Yield Maintenance Charges, Balloon Payments or Excess
Interest, (ii) the amount required to be advanced in respect of delinquent
Monthly Payments and Assumed Scheduled Payments on any Loan that has been
subject to an Appraisal Reduction will equal, with respect to any Distribution
Date, the amount that would be required to be advanced by the Servicer without
giving effect to the Appraisal Reduction, less the Appraisal Reduction Amount,
for such Distribution Date, and (iii) if the monthly payment on any Loan has
been reduced or the final maturity 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 monthly payment due and owing during the extension period is less than
the amount of the Monthly Payments prior to such modification, then the Servicer
shall, as to such Loan only, advance only the amount of the Monthly Payment due
and owing after taking into account such reduction (net of related Primary
Servicing Fees, Servicing Fees and Workout Fees), in the event of subsequent
delinquencies thereon.

            (f) Upon receipt of notice of a Residual Value Policy Termination
Event, the Servicer shall:

               (i) Maintain a record of all payments by the related Residual
      Value Insurer (the aggregate amount already paid at such time, together
      with all subsequent payments made from time to time thereafter, under the
      Residual Value Policy, the "Residual Value Policy Exposure").

               (ii) Make no P&I Advance with respect to the related Loan to the
      extent that such P&I Advance, taking into account any Residual Value
      Policy Exposure, would constitute a Nonrecoverable P&I Advance.

               (iii) Upon determination that, with respect to such Loan, any P&I
      Advance (or portion thereof) relating to a payment (or portion thereof) by
      the Residual Value Policy Insurer, taking into account the Residual Value
      Policy Exposure, constituted a Nonrecoverable Advance, deposit into an
      account (the "Policy Escrow Account") established and maintained by the
      Servicer as an Eligible Account all payments made under the related
      Residual Value Policy after the date of such determination until the date
      on which ultimate responsibility (as between the Trust Fund and the
      Residual Value Policy Insurer) for payments with respect to such Lease
      Enhancement Policy Termination Event is finally resolved. Amounts
      deposited in the Policy Escrow Account shall be invested in Permitted
      Investments selected by the Servicer pursuant to Section 3.06.

               (iv) If any payment (or portion thereof) made by any Residual
      Value Insurer is subsequently determined, in accordance with the dispute
      resolution procedures set forth in the related Residual Value Policy or
      pursuant to any legal process or settlement by the Special Servicer of any
      claim by such Residual Value Insurer, to be reimbursable to the Residual
      Value Insurer, (a) remit to such Residual Value Insurer the amount on
      deposit in the Policy Escrow Account (up to the amount owed to the
      Residual Value Insurer), (b) make a P&I Advance of any remaining amount
      owed to the Residual Value Insurer and (c) promptly pay the amount of such
      P&I Advance to such Residual Value Insurer under the Residual Value Policy
      with respect to such Residual Value Policy Termination Event. If such P&I
      Advance is determined to be a Nonrecoverable P&I Advance, the Servicer
      shall nevertheless make such P&I Advance to the related Residual Value
      Insurer to reimburse it for amounts paid out under the Residual Value
      Policy as provided above, but the Servicer shall be entitled to
      immediately reimburse itself from general funds available in the
      Collection Account for such P&I Advance as a Nonrecoverable Advance. If
      such P&I Advance is not determined to be a Nonrecoverable P&I Advance, the
      Servicer shall be repaid therefor out of the proceeds of the related Loan.

               (v) If any payment (or portion thereof) made by such Residual
      Value Insurer and deposited into the Policy Escrow Account is subsequently
      determined to have been properly payable to the Trust Fund, then the
      Servicer shall deposit into the Collection Account the amount on deposit
      in the Policy Escrow Account (net of any interest and investment income
      realized on funds on deposit therein that, pursuant to Section 3.06(a), is
      to be applied to pay interest on Advances made with respect to, or other
      expenses of the Trust Fund allocable to, the related Loan), together with
      any payments in the nature of damages relating to non-payment under such
      Residual Value Insurance Policy, as recoveries with respect to such Loan.

            (g) With respect to each Due Period, if any, in which Additional
Collateral Prepayment Amounts are paid pursuant to the terms of one or more
Additional Collateral Loans, the Servicer shall make an advance to the Yield
Protection Payment Account on the related Servicer Remittance Date in an amount
equal to the aggregate Yield Protection Payments, if any, for the related
Distribution Date (such advance, a "Yield Protection Payment Advance"). The
Servicer's obligation to make Yield Protection Payment Advances shall be in
consideration for, and conditioned upon, the CSFB Mortgage Loan Seller's
agreement to reimburse the Servicer therefor pursuant to the applicable
agreement between the Servicer and the CSFB Mortgage Loan Seller. In no event
shall the Servicer be entitled to reimbursement from the Trust Fund or the MS
Mortgage Loan Seller for any Yield Protection Payment Advance.

            Section 4.04      Allocation of Collateral Support Deficit.

            (a) On each Distribution Date, immediately following the
distributions to be made on such date pursuant to Section 4.01 and the
allocation of Certificate Deferred Interest pursuant to Section 4.06, the
Certificate Administrator shall calculate the amount, if any, by which (i) the
aggregate Stated Principal Balance of the Loans and any REO Loans expected to be
outstanding immediately following such Distribution Date is less than (ii) the
then aggregate Certificate Balance of the Regular Certificates after giving
effect to distributions of principal on such Distribution Date and the
allocation of Certificate Deferred Interest pursuant to Section 4.06 (any such
deficit, the "Collateral Support Deficit"). Any allocation of Collateral Support
Deficit to a Class of Regular Certificates shall be made by reducing the
Certificate Balance thereof by the amount so allocated. Any Collateral Support
Deficit allocated to a Class of Regular Certificates shall be allocated among
the respective Certificates of such Class in proportion to the Percentage
Interests evidenced thereby. The allocation of Collateral Support Deficit shall
constitute an allocation of losses and other shortfalls experienced by the Trust
Fund. Reimbursement of previously allocated Collateral Support Deficit will not
constitute distributions of principal for any purpose and will not result in an
additional reduction in the Certificate Balance of the Class of Certificates in
respect of which any such reimbursement is made.

            (b) On each Distribution Date, the Certificate Balances of the
Regular Certificates will be reduced without distribution to the extent of any
Collateral Support Deficit, if any, allocable to such Certificates with respect
to such Distribution Date. Such reductions shall be allocated among the
respective Certificates as follows: first, to the Class O Certificates; second,
to the Class N Certificates; third, to the Class M Certificates; fourth, to the
Class L Certificates; fifth, to the Class K Certificates; sixth, to the Class J
Certificates; seventh, to the Class H Certificates, eighth, to the Class G
Certificates, ninth, to the Class F Certificates, tenth, to the Class E
Certificates, eleventh, to the Class D Certificates, twelfth, to the Class C
Certificates, and thirteenth, to the Class B Certificates, in each case, until
the remaining Certificate Balance of each such Class of Certificates has been
reduced to zero. Following the reduction of the Certificate Balances of all such
Classes to zero, any remaining Collateral Support Deficit shall be allocated
among the Class A-1 and Class A-2 Certificates, pro rata (based upon the
Certificate Balance of each such Class), until the remaining Certificate
Balances of such Classes have been reduced to zero. Any Collateral Support
Deficit allocated to a Class of Certificates will be allocated among respective
Certificates of such Class in proportion to the Percentage Interests evidenced
thereby.

            (c) With respect to any Distribution Date, any Collateral Support
Deficit allocated to a Class of Certificates pursuant to Section 4.04(b) with
respect to such Distribution Date shall reduce the Lower-Tier Principal Amounts
of the Related Uncertificated Lower-Tier Interest with respect thereto as a
write-off.

            Section 4.05      Appraisal Reductions.

            The aggregate Appraisal Reductions will be allocated by the
Certificate Administrator on each Distribution Date to the Certificate Balance
of the Class O, Class N, Class M, Class L, Class K, Class J, Class H, Class G,
Class F, Class E, Class D, Class C and Class B Certificates, in that order, up
to the amount of their respective Certificate Balances, for purposes of
determining (x) the amount of P&I Advances with respect to the related Loans,
(y) Voting Rights and (z) the identity of the Controlling Class. On any
Distribution Date, an Appraisal Reduction that otherwise would be allocated to a
Class of Certificates shall be allocated to the next most subordinate Class to
the extent that the Certificate Balance on such Distribution Date for such Class
of Certificates (prior to taking the Appraisal Reduction into account) is less
than the Appraisal Reduction for such Distribution Date.

            By 4:00 p.m., New York City time, on the third Business Day
immediately preceding each Distribution Date with respect to which one or more
Appraisal Reductions exist, the Servicer shall notify the Certificate
Administrator in writing of such Appraisal Reductions and by the close of
business of the second Business Day immediately preceding each such Distribution
Date, the Certificate Administrator shall identify to the Servicer in writing
each Class of Subordinate Certificates to which one or more Appraisal Reductions
shall be allocated on such Distribution Date, the applicable Pass-Through Rate
of each such Class, and the amount of Appraisal Reductions allocated to each
such Class.

            Section 4.06      Certificate Deferred Interest.

            (a) On each Distribution Date, the Monthly Interest Distribution
Amount for the Regular Certificates (other than the Class A-X Certificates)
shall be reduced by an amount of Certificate Deferred Interest equal to the
aggregate amount of Mortgage Deferred Interest for all Loans for the related Due
Date allocated to such Class of Certificates, the amount representing such
Certificate Deferred Interest to be allocated, to the Class O Certificates, to
the Class N Certificates, to the Class M Certificates, to the Class L
Certificates, to the Class K Certificates, to the Class J Certificates, to the
Class H Certificates, to the Class G Certificates, to the Class F Certificates,
to the Class E Certificates, to the Class D Certificates, to the Class C
Certificates and to the Class B Certificates, in that order. If the Certificate
Balance of at least one Class of Class A Certificates is not zero, then any
amounts representing Certificate Deferred Interest after allocation thereof to
the Subordinate Certificates in accordance with the preceding sentence will be
allocated to the Class A Certificates pro rata on the basis of the respective
interest entitlements of such Class on such date (before giving effect to any
reduction therefrom on such Distribution Date).

            (b) On each Distribution Date, the Certificate Balances of the Class
A-1, Class A-2, Class B, Class C, Class D, Class E, Class F, Class G, Class H,
Class J, Class K, Class L, Class M, Class N and Class O Certificates shall be
increased (except for the purposes of determining Voting Rights or the identity
of the Controlling Class) by the amount of the Certificate Deferred Interest
allocated to such Class of Certificates on such Distribution Date pursuant to
Section 4.06(a) above.

            (c) With respect to any Distribution Date, any Certificate Deferred
Interest with respect to such Distribution Date allocated pursuant to Section
4.06(a) to a Class of Certificates shall be allocated in reduction of the amount
of interest distributable to the Related Uncertificated Lower-Tier Interest with
respect thereto. On each Distribution Date, to the extent provided in Section
4.06(b), Certificate Deferred Interest will be added to the Lower-Tier Principal
Amount of the Uncertificated Lower-Tier Interests in the same manner as the
interest thereon was reduced pursuant to the preceding sentence.

            Section 4.07      Grantor Trust Reporting.

            The parties intend that the portions of the Trust Fund consisting of
Excess Interest, the Excess Interest Distribution Account, Yield Protection
Payments and the Yield Protection Payment Account shall constitute, and that the
affairs of the Trust Fund (exclusive of the Upper-Tier REMIC and the Lower-Tier
REMIC) shall be conducted so as to qualify such portions as, a "grantor trust"
under the Code, and the provisions hereof shall be interpreted consistently with
this intention. In furtherance of such intention, the Certificate Administrator
(i) shall furnish or cause to be furnished to Class V-1 and Class V-2
Certificateholders and shall file, or cause to be filed with the Internal
Revenue Service, together with Form 1041 or such other form as may be
applicable, information returns with respect to income relating to their share
of Excess Interest and, at the time or times and in the manner required by the
Code and (ii) shall furnish or cause to be furnished to the Class A-X
Certificateholders and to the Holders of any Class of Regular Certificates
receiving a Class A-X Yield Protection Payment Amount or a Regular Yield
Protection Payment Amount, respectively, and shall file, or cause to be filed
with the Internal Revenue Service together with Form 1041 or such other form as
may be applicable, information returns with respect to income relating to their
applicable share of Yield Protection Payments at the time or times and in the
manner required by the Code. The Yield Protection Payments shall be treated as
part of a grantor trust for federal income tax reporting purposes.

                                THE CERTIFICATES

            Section 5.01      The Certificates.

            (a) The Private Certificates will be offered only to Qualified
Institutional Buyers. The Class G and Class H Certificates will be offered only
to Qualified Institutional Buyers and Non-U.S. Persons. The Class O Certificates
will be offered only to Qualified Institutional Buyers and Institutional
Accredited Investors. Interests in the Class G and Class H Certificates will be
offered (i) in the form of beneficial interests in restricted global
certificates in definitive, fully registered form without interest coupons,
deposited with the Certificate Administrator, as custodian for DTC, and
registered in the name of Cede & Co. ("Cede") DTC's nominee or (ii) in fully
registered, certificated form. The Class J, Class K, Class L, Class M, Class N
and Class O Certificates will be offered in fully registered, certificated form.

            Class G Certificates and Class H Certificates sold in reliance on
Rule 144A under the Securities Act will be represented by one or more Private
Global Certificates (each, a "Rule 144A Global Certificate"). Class G
Certificates and Class H Certificates sold in reliance on Regulation S under the
Securities Act will be represented by one or more Private Global Certificates
(each, a "Regulation S Global Certificate"). Beneficial interests in a
Regulation S Global Certificate may be held only through Euroclear or Cedelbank
at any time and may not be held by a U.S. Person at any time.

            (b) The Certificates shall be substantially in the respective forms
annexed hereto as Exhibits A-1 through and including A-7. The Certificates shall
be issuable in registered form only; provided, however, that in accordance with
Section 5.03, beneficial ownership interests in the Regular Certificates (other
than the Private Definitive Certificates) shall initially be held and
transferred through the book-entry facilities of the Depository. The Class V-1,
Class V-2, Class R and Class LR Certificates, and all Private Definitive
Certificates, shall be issuable as Definitive Certificates. Each Certificate
shall share ratably in all rights of the related Class.

            The Class A-X Certificates shall be issuable only in Denominations
of authorized initial Notional Balance of not less than $100,000 and integral
multiples of $1 in excess thereof. The Class O Certificates shall be issuable
only in Denominations of authorized initial Certificate Balance of not less than
$100,000 and integral multiples of $1 in excess thereof. The Regular
Certificates (other than the Class A-X Certificates and Class O Certificates)
will be issuable only in Denominations of authorized initial Certificate Balance
of not less than $25,000 and integral multiples of $1 in excess thereof. The
Class V-1, Class V-2, Class R and Class LR Certificates will be issuable only as
one or more Definitive Certificates in Denominations representing Percentage
Interests of not less than 15%.

            With respect to any Certificate or any beneficial interest in a
Certificate, the "Denomination" thereof shall be (i) the amount set forth on the
face thereof or on a schedule attached thereto, (ii) in the case of any
beneficial interest in a Book-Entry Certificate, the interest of the related
Certificate Owner in the applicable Class of Certificates as reflected on the
books and records of the Depository or related Depository Participants, as
applicable, (iii) expressed in terms of initial Certificate Balance or initial
Notional Balance, as applicable, and (iii) in an authorized Denomination, as set
forth above. The Book-Entry Certificates will be issued as one or more
certificates registered in the name of a nominee designated by the Depository,
and Certificate Owners will hold interests in the Book-Entry Certificates
through the book-entry facilities of the Depository in the minimum Denominations
and aggregate Denominations as set forth above.

            The Holder of a Class G or Class H Certificate represented by a
Private Definitive Certificate shall be entitled to exchange such Certificate
for an interest in a Private Global Certificate, in accordance with the
procedures described in Section 5.03(g). A Certificate Owner of a Private Global
Certificate shall be entitled to receive a Definitive Certificate representing
its interest in such Certificate in accordance with the procedures described in
Section 5.03(c)(i). No Certificate Owner of a Public Certificate of any Class
shall be entitled to receive a Definitive Certificate representing its interest
in such Class, except as provided in Section 5.03(c)(ii). Unless and until
Definitive Certificates are issued in respect of a Class of Public Certificates,
or in substitution for a Certificate that is a Private Global Certificate,
beneficial ownership interests in such Class of Certificates, or in such Private
Global Certificate, shall be maintained and transferred on the book-entry
records of the Depository and Depository Participants, and all references to
actions by Holders of such Class of Certificates, or Holders of such Private
Global Certificates, shall be references to actions taken by the Depository upon
instructions received from the related registered Holders of Certificates
through the Depository Participants in accordance with the Depository's
procedures and, except as otherwise set forth herein, all references herein to
payments, notices, reports and statements to Holders of such Class of
Certificates, or Holders of Private Global Certificates, shall be references to
payments, notices, reports and statements to the Depository or its nominee as
the registered Holder thereof, for distribution to the related registered
Holders of Certificates through the Depository Participants in accordance with
the Depository's procedures.

            (c) The Certificates shall be executed by manual or facsimile
signature on behalf of the Certificate Registrar 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. The Certificate
Administrator is hereby initially appointed Authenticating Agent with power to
act on the Trustee's behalf in the authentication and delivery of the
Certificates in connection with transfers and exchanges as herein provided. If
the Authenticating Agent resigns or is terminated, the Trustee shall appoint a
successor Authenticating Agent which may be the Trustee or an Affiliate thereof.

            (d) 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.

            (e) If the Trust Fund ceases to be subject to Section 13 or 15(d) of
the Exchange Act, the Trustee shall make available to each Holder of a Class R
or Class LR Certificate, upon request of such a Holder, information
substantially equivalent in scope to the information currently filed by the
Trustee with the Commission pursuant to the Exchange Act, plus such additional
information required to be provided for securities qualifying for resales under
Rule 144A under the Act.

            For so long as the Class R or Class LR Certificates remain
outstanding, neither the Depositor nor the Trustee nor the Certificate Registrar
shall take any action which would cause the Trust Fund to fail to be subject to
Section 15(d) of the Exchange Act.

            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 shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.
The Certificate Administrator is hereby initially appointed 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 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 Norwest Bank Minnesota, National Association, resigns as
Certificate Registrar, the entity succeeding Norwest Bank Minnesota, National
Association, as Certificate Administrator shall immediately succeed to its
predecessor's duties as Certificate Registrar. The Depositor, the Trustee, the
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. The names and addresses of
all Certificateholders and the names and addresses of the transferees of any
Certificates shall be registered in the Certificate Register; provided, however,
in no event shall the Certificate Registrar be required to maintain in the
Certificate Register the names of Certificate Owners.

            The Person in whose name any Certificate is so registered shall be
deemed and treated as the sole owner and Holder thereof for all purposes of this
Agreement and the Certificate Registrar, the Servicer, the Trustee, the Special
Servicer and any agent of any of them shall not be affected by any notice or
knowledge to the contrary. A Definitive Certificate is transferable or
exchangeable only upon the surrender of such Certificate to the Certificate
Registrar at its office maintained at Norwest Center, Sixth Street and Marquette
Avenue, Minneapolis, Minnesota 55479-0113, Attention: Corporate Trust Services
(CMBS) - CSFB 1999-C1, or at the Corporate Trust Office, if the Trustee is the
Certificate Registrar (the "Registrar Office") together with an assignment and
transfer (executed by the Holder or his duly authorized attorney).

            Subject to the requirements of Sections 5.02(b), (c) and (d), the
Certificate Registrar shall execute and authenticate in the name of the
designated transferee or transferees, in the case of a Definitive Certificate
being surrendered in exchange for one or more new Definitive Certificates, one
or more new Certificates in Denominations equal in the aggregate to the
Denomination of the Definitive Certificate being surrendered. Such new
Certificates shall be delivered by the Certificate Registrar in accordance with
Section 5.02(e).

            Each Certificate surrendered for registration of transfer shall be
canceled, and the Certificate Registrar shall hold such canceled Certificate in
accordance with its standard procedures.

            (b) No transfer of any Private 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 (other than one by the Depositor to
an Affiliate thereof) of a Private Certificate is to be made in reliance upon an
exemption from the Securities Act, and under the applicable state securities
laws, then either:

               (i) the Certificate Registrar shall require the transferee to
      deliver to the Certificate Registrar an investment representation letter
      substantially in the form of Exhibit C-1 attached hereto (a "QIB
      Investment Representation Letter"), which shall certify, among other
      things, that the transferee is a "qualified institutional buyer" as
      defined in Rule 144A under the Securities Act (a "Qualified Institutional
      Buyer"); or

               (ii) with respect to the Class G and Class H Certificates only,
      the Certificate Registrar shall require the transferee to deliver to the
      Certificate Registrar an investment representation letter substantially in
      the form of Exhibit C-2 attached hereto (a "Regulation S Investment
      Representation Letter"), which will certify, among other things, that the
      transferee is not a "U.S. Person" within the meaning of Regulation S under
      the Securities Act; or

               (iii) with respect to the Class O Certificates only, the
      Certificate Registrar shall require the transferee to deliver to the
      Certificate Registrar an investment representation letter substantially in
      the form of Exhibit C-3 attached hereto, which shall certify, among other
      things, that the transferee is an institutional "accredited investor" as
      defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act (an
      "Institutional Accredited Investor") and is acquiring such Private
      Certificate for investment, either for its own account (and not for the
      account of others) or as a fiduciary or agent for others (which others
      also are Accredited Investors), and not with a view to, or for offer or
      sale in connection with, the public distribution thereof.

            If the certification described in the preceding clause (i) cannot be
provided, (a) the Certificate Registrar shall require an Opinion of Counsel
reasonably satisfactory to the Certificate Registrar and the Depositor that such
transfer may be made pursuant to an exemption, describing the applicable
exemption and the basis therefor, from registration or qualification under the
Securities Act, applicable state securities laws and other relevant laws, which
Opinion of Counsel shall not be at the expense of the Trust Fund, the
Certificate Registrar, the Depositor or the Trustee and (b) the Certificate
Registrar shall require the transferor (other than the Underwriters, in
connection with its initial transfer of the Certificate being transferred) to
execute a certification in form and substance satisfactory to the Certificate
Registrar setting forth the facts surrounding such transfer; provided, however,
that a transfer of a Private Certificate of any such Class may be made to a
trust if the transferor provides to the Certificate Registrar and to the Trustee
a certification that interests in such trust may only be transferred subject to
requirements substantially to the effect set forth in this Section 5.02.

            The Servicer shall furnish to the Certificate Administrator, which
shall furnish, or cause to be furnished, upon the request of any Holder of a
Private Certificate, any such information as is specified in paragraph (d)(4) of
Rule 144A with respect to the Trust Fund, unless, at the time of such request,
the entity with respect to which such information is to be provided is subject
to the reporting requirements of Section 13 or 15(d) of the Exchange Act. None
of the Depositor, the Trustee, the Servicer or the Certificate Registrar is
obligated to register or qualify any Class of Private 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 Private Certificate
without registration or qualification. Any Holder of a Private Certificate
desiring to effect such a transfer shall, and does hereby agree to, indemnify
the Depositor, the Trustee, the Servicer and the Certificate Registrar 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. Unless the Certificate Registrar
determines otherwise in accordance with applicable law and the rules and
procedures of, or applicable to, the Depository (the "Depository Rules"),
transfers of a beneficial interest Private Global Certificate that is not rated
in one of the top four rating categories by a nationally recognized statistical
rating organization may be effectuated only by means of an "SRO Rule 144A
System" approved for such purpose by the Commission.

            No Class V-1 Certificate may be transferred to an Ineligible Class
V-1 Owner. No Class V-2 Certificate may be transferred to an Ineligible Class
V-2 Owner.

            (c) (3) Unless a Class of Private Global Certificates has been
registered under the Securities Act, each Certificate of such Class shall bear a
legend substantially to the following effect:

            THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
            1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES
            LAWS. NEITHER THIS CERTIFICATE NOR ANY INTEREST OR PARTICIPATION
            HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED,

            REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT
            SUBJECT TO, REGISTRATION UNDER THE SECURITIES ACT.

            THE HOLDER OF THIS CERTIFICATE BY ITS ACCEPTANCE HEREOF AGREES NOT
            TO OFFER, SELL OR OTHERWISE TRANSFER SUCH CERTIFICATE EXCEPT IN
            ACCORDANCE WITH ALL APPLICABLE STATE SECURITIES LAWS AND (A)
            PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BEEN DECLARED

            A PERSON WHO IS NOT A "U.S. PERSON" AS DEFINED IN REGULATION S UNDER
            THE SECURITIES ACT, (D) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM
            THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT IN EACH
            OF THE FOREGOING CASES TO THE COMPLETION AND DELIVERY BY THE
            TRANSFEROR TO THE CERTIFICATE REGISTRAR OF A CERTIFICATE OF TRANSFER
            IN THE FORM APPEARING ON THE LAST PAGE OF THIS CERTIFICATE.

            THE HOLDER OF THIS CERTIFICATE, AND EACH SUBSEQUENT PURCHASER OF
            THIS CERTIFICATE, BY PURCHASING THIS CERTIFICATE OR AN INTEREST
            HEREIN, IS DEEMED TO HAVE AGREED TO COMPLY WITH CERTAIN TRANSFER
            REQUIREMENTS SET FORTH IN THE POOLING AND SERVICING AGREEMENT, AND

            LETTER SUBSTANTIALLY IN THE FORM OF AN EXHIBIT TO THE POOLING AND

            (e) With respect to any Certificate other than a Class A Certificate
or a Class A-X Certificate, no sale, transfer, pledge or other disposition by
any Holder of any such Certificate shall be made unless the Certificate
Registrar shall have received either (i) a representation letter from the
proposed purchaser or transferee of such Certificate to the effect that such
proposed purchaser or transferee is not (a) an employee benefit plan subject to
the fiduciary responsibility provisions of ERISA or Section 4975 of the Code, or
a governmental plan (as defined in Section 3(32) of ERISA) subject to any
federal, state or local law ("Similar Law") which is, to a material extent,
similar to the foregoing provisions of ERISA or the Code (each, a "Plan") or (b)
a person acting on behalf of or using the assets of any such Plan (including an
entity whose underlying assets include Plan assets by reason of investment in
the entity by such Plan and the application of Department of Labor Regulation
ss. 2510.3-101), other than (except in the case of a Class R or Class LR
Certificate) an insurance company using the assets of its general account under
circumstances whereby the purchase and holding of such Certificates by such
insurance company would be eligible for the exemptive relief from the prohibited
transaction provisions of ERISA and Section 4975 of the Code that is available
under Sections I and III of Prohibited Transaction Class Exemption 95-60 (it
being understood that delivery of a representation letter containing a
representation substantially in the form of paragraph 8 of Exhibit C attached
hereto shall satisfy the requirement of this Section 5.02(d)(i)), or (ii) if
such Certificate is presented for registration in the name of a purchaser or
transferee that is any of the foregoing, an Opinion of Counsel in form and
substance satisfactory to the Trustee, the Certificate Registrar and the
Depositor to the effect that the acquisition and holding of such Certificate by
such purchaser or transferee will not constitute or result in a non-exempt
prohibited transaction under ERISA, Section 4975 of the Code or any Similar Law
and will not subject the Trustee, the Certificate Registrar, the Servicer, the
Special Servicer, the Underwriters, the Initial Purchaser or the Depositor to
any obligation or liability (including obligations or liabilities under ERISA,
Section 4975 of the Code or any Similar Law) in addition to those set forth in
the Agreement.

            The Certificate Registrar shall not register the sale, transfer,
pledge or other disposition of any such Certificate unless the Certificate
Registrar has received either the representation letter described in clause (i)
above or the Opinion of Counsel described in clause (ii) above. The costs of any
of the foregoing representation letters or Opinions of Counsel shall not be
borne by any of the Depositor, the Servicer, the Special Servicer, the
Certificate Registrar, the Trustee and the Trust Fund. Each Certificate Owner of
a Certificate other than a Class A or Class A-X Certificate shall be deemed to
represent that it is not a Person specified in clauses (a), or (b) above. Any
transfer, sale, pledge or other disposition of any such Certificates that would
constitute or result in a prohibited transaction under ERISA, Section 4975 of
the Code or any Similar Law, or would otherwise violate the provisions of this
Section 5.02(c) shall be deemed absolutely null and void ab initio, to the
extent permitted under applicable law.

            So long as any Class of Certificates other than the Class A and
Class A-X Certificates remains outstanding, the Servicer will make available, or
cause to be made available, upon written request with sufficient notice during
normal business hours, to any Holder and any Person to whom any such Certificate
of any such Class of Certificates may be offered or sold, transferred, pledged
or otherwise disposed of by such Holder, information with respect to the
Servicer, the Special Servicer or the Loans reasonably necessary to the
provision of an Opinion of Counsel described in this Section 5.02(c).

            (f) Notwithstanding any provision to the contrary herein, so long as
a Private Global Certificate remains outstanding and is held by or on behalf of
DTC, transfers of a Private Global Certificate, in whole or in part, shall only
be made in accordance with this Article V.

               (i) Regulation S Global Certificate to Rule 144A Global
      Certificate. If a holder of a beneficial interest in a Regulation S Global
      Certificate deposited with DTC wishes at any time to transfer its interest
      in such Regulation S Global Certificate to a Person who wishes to take
      delivery thereof in the form of a Rule 144A Global Certificate, such
      holder may, subject to the rules and procedures of Euroclear, Cedelbank or
      DTC, as the case may be, exchange or cause the exchange of such interest
      for an equivalent beneficial interest in a Rule 144A Global Certificate.
      Upon receipt by the Certificate Administrator, as custodian for DTC, of
      (A) instructions from Euroclear, Cedelbank or DTC, as the case may be,
      directing the Certificate Administrator, as such custodian, to cause to be
      issued a Rule 144A Global Certificate in an amount equal to the beneficial
      interest in such Regulation S Global Certificate, but not less than the
      minimum denomination applicable to such holder's Certificates to be
      exchanged, and (B) a certificate in the form of Exhibit C-1 attached
      hereto given by the holder of such beneficial interest and stating, among
      other things, that the Person transferring such beneficial interest in
      such Regulation S Global Certificate reasonably believes that the Person
      acquiring such interest in a Rule 144A Global Certificate is a qualified
      institutional buyer within the meaning of Rule 144A, is obtaining such
      beneficial interest in a transaction meeting the requirements of Rule 144A
      and in accordance with any applicable Securities laws of any State of the
      United States or any other applicable jurisdiction and that such Person
      acquiring such Rule 144A Global Certificate is a "U.S. person" as defined
      in Regulation S under the Securities Act, then Euroclear or Cedelbank or
      the Certificate Administrator, as custodian for DTC, as the case may be,
      will instruct the Certificate Administrator, as custodian for DTC, to
      reduce the Regulation S Global Certificate by the aggregate principal
      amount of the Rule 144A Global Certificate to be transferred and the
      Certificate Administrator, as such custodian, shall authenticate and
      deliver such Rule 144A Global Certificate, concurrently with such
      reduction, to the Person specified in such instructions with an
      outstanding principal amount equal to the reduction in the principal
      amount of the Regulation S Global Certificate.

               (ii) Rule 144A Global Certificate to Regulation S Global
      Certificate. If a holder of a beneficial interest in one or more Rule 144A
      Global Certificates wishes at any time to exchange its interest in such
      Rule 144A Global Certificate for an interest in a Regulation S Global
      Certificate, or to transfer its interest in such Rule 144A Global
      Certificate to a Person who wishes to take delivery thereof in the form of
      an interest in a Regulation S Global Certificate, such holder, provided
      such holder is not a U.S. Person, may exchange or cause the exchange of
      such interest for an equivalent beneficial interest in a Regulation S
      Global Certificate. Upon receipt by the Certificate Administrator, as
      custodian for DTC, of (A) such Rule 144A Global Certificate properly
      endorsed for such transfer and written instructions from such holder
      directing the Certificate Administrator, as such custodian, to cause to be
      credited a beneficial interest in a Regulation S Global Certificate in an
      amount equal to the beneficial interest in the Rule 144A Global
      Certificate, but not less than the minimum denomination applicable to such
      holder's Certificates held through a Regulation S Global Certificate, to
      be exchanged, (B) a written order containing information regarding the
      Euroclear or Cedelbank account to be credited with such increase and (C) a
      certificate in the form of Exhibit C-2 attached hereto given by the holder
      of such beneficial interest stating that the exchange or transfer of such
      interest has been made in compliance with the transfer restrictions
      applicable to the Private Global Certificates, including that the holder
      is not a U.S. Person, and pursuant to and in accordance with Regulation S
      under the Securities Act, the Certificate Administrator, as custodian for
      DTC, shall record the transfer in the Registrar Office and shall increase
      the principal amount of the Regulation S Global Certificate by the
      outstanding principal amount of the beneficial interest in the Rule 144A
      Global Certificate to be exchanged, and to credit, or cause to be credited
      to the account of the Person specified in such instructions, a beneficial
      interest in the Regulation S Global Certificate equal to the amount
      specified in the instructions received pursuant to clause (i) above.

            (g) (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 Certificate Administrator under clause
(ii) below to deliver payments to a Person other than such Person. The rights of
each Person acquiring any Ownership Interest in a Residual Certificate are
expressly subject to the following provisions:

                  (A) No Person holding or acquiring any Ownership Interest in a
            Residual Certificate shall be a Disqualified Organization or agent
            thereof (including a nominee, middleman or similar person) (an
            "Agent"), a Plan or a Person acting on behalf of or investing the
            assets of a Plan (such Plan or Person, an "ERISA Prohibited Holder")
            or a Non-U.S. Person and shall promptly notify the Servicer, the
            Trustee and the Certificate Registrar of any change or impending
            change to such status;

                  (B) In connection with any proposed Transfer of any Ownership
            Interest in a Residual Certificate, the Certificate Registrar shall
            require delivery to it, and no Transfer of any Residual Certificate
            shall be registered until the Certificate Registrar receives, an
            affidavit substantially in the form attached hereto as Exhibit D-1
            (a "Transfer Affidavit") from the proposed Transferee, in form and
            substance satisfactory to the Certificate Registrar, representing
            and warranting, among other things, that such Transferee is not a
            Disqualified Organization or Agent thereof, an ERISA Prohibited
            Holder or a Non-U.S. Person, and that it has reviewed the provisions
            of this Section 5.02(g) and agrees to be bound by them;

                  (C) Notwithstanding the delivery of a Transfer Affidavit by a
            proposed Transferee under clause (B) above, if a Responsible Officer
            of the Certificate Registrar has actual knowledge that the proposed
            Transferee is a Disqualified Organization or Agent thereof, an ERISA
            Prohibited Holder or a Non-U.S. Person, 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 (1) to require a Transfer
            Affidavit from any prospective Transferee to whom such Person
            attempts to transfer its Ownership Interest in such Residual
            Certificate and (2) not to transfer its Ownership Interest in such
            Residual Certificate unless it provides to the Certificate Registrar
            a letter substantially in the form attached hereto as Exhibit D-2 (a
            "Transferor Letter") certifying that, among other things, it has no
            actual knowledge that such prospective Transferee is a Disqualified
            Organization or Agent thereof, an ERISA Prohibited Holder or a
            Non-U.S. Person and that (if the Transferor is not a U.S. Person)
            such transfer does not have the effect of allowing the Transferor to
            avoid tax on accrued excess inclusions; and

                  (E) In addition, the Certificate Registrar may as a condition
            of the registration of any such transfer require the transferor to
            furnish such other certifications, legal opinions or other
            information (at the transferor's expense) as it may reasonably
            require to confirm that the proposed transfer is being made pursuant
            to an exemption from, or in a transaction not subject to, the
            registration requirements of the Securities Act and other applicable
            laws.

               (ii) If any purported Transferee shall become a Holder of a
      Residual Certificate in violation of the provisions of this Section
      5.02(g), then the last preceding Holder of such Residual Certificate that
      was in compliance with the provisions of this Section 5.02(g) 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 Servicer, the Authenticating Agent
      and 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.

               (iii) The Servicer shall make available to the Internal Revenue
      Service and those Persons specified by the REMIC Provisions, upon written
      request of the Certificate Administrator, all information in its
      possession and 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.

            (h) Subject to the restrictions on transfer and exchange set forth
in this Section 5.02, the Holder of any Definitive Certificate may transfer or
exchange the same in whole or in part (with a Denomination equal to any
authorized denomination) by surrendering such Certificate at the Registrar
Office or at the office of any successor Certificate Registrar or transfer agent
appointed by the Certificate Registrar, together with an instrument of
assignment or transfer (executed by the Holder or its duly authorized attorney),
in the case of transfer, and a written request for exchange in the case of
exchange.

            Following a proper request for transfer or exchange, the Certificate
Registrar shall, within five Business Days of such request if made at such
Registrar Office, or within 10 Business Days if made at the office of a transfer
agent (other than the Certificate Registrar), execute and deliver at such
Registrar Office or at the office of such transfer agent, as the case may be, to
the transferee (in the case of transfer) or Holder (in the case of exchange) or
send by first-class mail (at the risk of the transferee in the case of transfer
or Holder in the case of exchange) to such address as the transferee or Holder,
as applicable, may request in writing, a Definitive Certificate or Certificates,
as the case may require, for a like aggregate Denomination and in such
Denomination or Denominations as may be requested. The Certificate Registrar may
decline to accept any request for an exchange or registration of transfer of any
Certificate during the period of 15 days preceding any Distribution Date.

            (i) If a Responsible Officer of the Certificate Registrar becomes
aware that a beneficial interest in a Private Global Certificate is being held
by or for the benefit of a Person who is not an Eligible Investor, or that a
Private Definitive Certificate is being held by or for the benefit of a Person
who is not an Eligible Investor or an Institutional Accredited Investor, or
that, in either case, such holding is unlawful under the laws of a relevant
jurisdiction, then the Certificate Registrar shall have the right, but not the
obligation, to void such transfer, if permitted under applicable law, or to
require the investor to sell (x) such Private Global Certificate to an Eligible
Investor or (y) the beneficial interest in such Private Definitive Certificate
to an Eligible Investor or an Institutional Accredited Investor, within 14 days
after notice of such determination, and each Certificateholder by its acceptance
of a Certificate authorizes the Certificate Registrar to take such action.

            (j) The Certificate Registrar shall provide notice to the Trustee,
the Servicer, the Special Servicer and the Depositor of the transfer of any
Private Definitive Certificate. The Certificate Owner of a Private Definitive
Certificate that wishes to receive the information described in Section 3.28(c)
shall provide notice to the Certificate Administrator, the Trustee, the
Servicer, the Special Servicer and the Depositor of the transfer of any
beneficial ownership in such Private Definitive Certificate and of the address
to which such information should be sent. Upon the written request of the
Trustee, the Servicer, the Special Servicer or the Depositor, the Certificate
Registrar shall provide each such Person with an updated copy of the Certificate
Register at the expense of the requesting party.

            (k) No fee or service charge shall be imposed by the Certificate
Registrar for its services in respect of any registration of transfer or
exchange referred to in this Section 5.02. With respect to any transfer or
exchange of any Certificate, the Certificate Registrar may require payment by
each transferor of a sum sufficient to cover any tax, expense or other
governmental charge payable in connection with any such transfer or exchange.

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

            Section 5.03      Book-Entry Certificates.

            (a) The Regular Certificates (except, the Class J, Class K, Class L,
Class M, Class N and Class O Certificates) initially shall be issued as one or
more Certificates registered in the name of the Depository or its nominee and,
except as provided in subsection (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, in the
case of the Public Certificates (except as provided in subsection (c)(i) below),
shall not be entitled to 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 such Certificate Owner. Each Depository Participant shall transfer
the Ownership Interests in the Book-Entry Certificates of Certificate Owners it
represents or of brokerage firms for which it acts as agent only in accordance
with the Depository's normal procedures. Neither the Trustee nor the Certificate
Registrar shall have any responsibility to monitor or restrict the transfer of
any ownership interest in a Book-Entry Certificate transferable through the
book-entry facilities of the Depository.

            (b) The Trustee, the 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 Certificate Administrator 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) (i) Upon the request of any Certificate Owner of Private Global
Certificates, or the transferee of such Certificate Owner, that its interest in
such Private Global Certificates be exchanged for Private Definitive
Certificates, such Certificate Owner or transferee, upon presentation of
appropriate documentation to the Certificate Administrator as required by this
Article V and subject to the rules and procedures of the Depositary, shall be
entitled to be issued one or more Private Definitive Certificates in
denominations authorized pursuant to Section 5.01(b) equal in the aggregate to
the Denomination of such interest in such Private Global Certificates.

            (d) If (A)(1) 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 the Book-Entry
Certificates and (2) the Depositor is unable to locate a qualified successor, or
(B) 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 some or all of the Classes, or (C) the
Certificate Administrator determines that Definitive Certificates are required
in accordance with the provisions of Section 5.03(e), the Certificate
Administrator shall notify the affected Certificate Owners, through the
Depository with respect to all Classes, any Class or any portion of any Class of
the Certificates, of the occurrence of any such event and of the availability of
Definitive Certificates to Certificate Owners requesting the same.

               (i)Upon surrender to the Certificate Registrar of the Book-Entry
      Certificates by the Depository or any custodian acting on behalf of the
      Depository, accompanied by registration instructions from the Depository
      for registration of transfer, the Certificate Registrar shall execute,
      authenticate and deliver, within five Business Days of such request if
      made at the Registrar Office, or within ten Business Days if made at the
      office of a transfer agent (other than the Certificate Registrar), the
      Definitive Certificates to the Certificate Owners identified in such
      instructions. None of the Depositor, the Servicer, the Trustee, the
      Special Servicer and 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 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.

            For purposes of any provision of this Pooling and Servicing
Agreement requiring or permitting actions with the consent of, or at the
direction of, Holders of Certificates evidencing a specified percentage of the
Voting Rights, such consent or direction may be given by a combination of
Certificate Owners (acting through the Depository and the Depository
Participants) owning Book-Entry Certificates, and Certificateholders owning
Definitive Certificates, evidencing in the aggregate such specified percentage
of the Voting Rights.

            (e) The Book-Entry Certificates (i) shall be delivered by the
Certificate Registrar to the Depository, or pursuant to the Depository's
instructions, and shall be registered in the name of Cede & Co. and (ii) shall
bear a legend substantially to the following effect:

            UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE
            OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO
            THE CERTIFICATE REGISTRAR 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.

            The Book-Entry Certificates may be deposited with such other
Depository as the Certificate Registrar may from time to time designate, and
shall bear such legend as may be appropriate.

            (f) If the Trustee has instituted or has been directed to institute
any judicial proceeding in a court to enforce the rights of the
Certificateholders under the Certificates, and the Trustee has been advised by
counsel that in connection with such proceeding it is necessary or appropriate
for the Trustee to obtain possession of all or any portion of the Certificates
evidenced by Book-Entry Certificates, the Trustee may in its sole discretion
determine that such Certificates shall no longer be represented by such
Book-Entry Certificates. In such event, the Certificate Registrar will execute,
authenticate and deliver, in exchange for such Book-Entry Certificates,
Definitive Certificates in a Denomination equal to the aggregate Denomination of
such Book-Entry Certificates to the party so requesting such Definitive
Certificates. In such event, the Certificate Administrator shall notify the
affected Certificate Owners and make appropriate arrangements for the
effectuation of the purpose of this clause.

            (g) Upon acceptance for exchange or transfer of a beneficial
interest in a Book-Entry Certificate for a Definitive Certificate, as provided
herein, the Certificate Registrar shall endorse on a schedule affixed to the
related Book-Entry Certificate (or on a continuation of such schedule affixed to
such Book-Entry Certificate and made a part thereof) an appropriate notation
evidencing the date of such exchange or transfer and a decrease in the
Denomination of such Book-Entry Certificate equal to the Denomination of such
Definitive Certificate issued in exchange therefor or upon transfer thereof.

            (h) If a Holder of a Definitive Certificate wishes at any time to
transfer such Certificate to a Person who wishes to take delivery thereof in the
form of a beneficial interest in the Book-Entry Certificate, such transfer may
be effected only in accordance with Depository Rules and this Section 5.03(h).
Upon receipt by the Certificate Registrar at the Registrar Office of (i) the
Definitive Certificate to be transferred with an assignment and transfer
pursuant to Section 5.02(a), (ii) written instructions given in accordance with
Depository Rules directing the Certificate Registrar to credit or cause to be
credited to another account a beneficial interest in the related Book-Entry
Certificate, in an amount equal to the Denomination of the Definitive
Certificate to be so transferred, (iii) a written order given in accordance with
the Depository Rules containing information regarding the account to be credited
with such beneficial interests (iv) if the affected Certificate is a Private
Certificate, a QIB Investment Representation Letter (or, if the affected
Certificate is a Class G or Class H Certificate, a Regulation S Investment
Representation Letter), the Certificate Registrar shall cancel such Definitive
Certificate, execute and deliver a new Definitive Certificate for the
Denomination of the Definitive Certificate not so transferred, registered in the
name of the Holder or the Holder's transferee (as instructed by the Holder), and
the Certificate Registrar shall instruct the Depository or the custodian holding
such Book-Entry Certificate on behalf of the Depository to increase the
Denomination of the related Book-Entry Certificate by the Denomination of the
Definitive Certificate to be so transferred, and to credit or cause to be
credited to the account of the Person specified in such instructions a
corresponding Denomination of such Book-Entry Certificate.

            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 or the Certificate Registrar that such Certificate has
been acquired by a bona fide purchaser, the Certificate Registrar shall execute
and 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
of 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 Trust Fund, 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 presentation of a Certificate for registration of
transfer, the Depositor, the Servicer, the Special Servicer, the Trustee, the
Certificate Registrar and any agents of any of them may treat the person in
whose name such Certificate is registered as the owner of such Certificate for
the purpose of receiving distributions pursuant to Section 4.01 and for all
other purposes whatsoever, except as and to the extent provided in the
definition of "Certificateholder," and none of the Depositor, the Servicer, the
Special Servicer, the Trustee, the Certificate Registrar and any agent of any of
them shall be affected by notice to the contrary except as provided in Section
5.02(d).

            Section 5.06      Access  to  Certificateholders'  Names  and
Addresses.

            (a) If any Certificateholder, the Special Servicer or the Servicer
(for purposes of this Section 5.05, an "Applicant") applies in writing to the
Certificate Registrar, and such application states that the Applicant desires to
communicate with other Certificateholders, the Certificate Registrar shall
furnish or cause to be furnished to such Applicant a list of the names and
addresses of the Certificateholders as of the most recent Record Date, at the
expense of the Applicant, in the case of any Certificateholder and the expense
of the Trust Fund in the case of the Servicer or the Special Servicer.

            (b) Every Certificateholder, by receiving and holding its
Certificate, agrees with the Trustee and the Certificate Registrar that the
Trustee and the Certificate Registrar shall not be held accountable in any way
by reason of the disclosure of any information as to the names and addresses of
the Certificateholders hereunder, regardless of the source from which such
information was derived.

            (c) From time to time, upon the request of and at no expense to the
Trustee, the Certificate Registrar shall deliver to the Trustee the list of
Certificateholders and their addresses as currently reflected in the Certificate
Register.

                               THE DEPOSITOR, THE
                        SERVICER AND THE SPECIAL SERVICER

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

            The Depositor, the 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 Servicer and the
Special Servicer herein.

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

            (a) Subject to subsection (b) below, the Depositor, the Servicer and
the Special Servicer each will keep in full effect its existence, rights and
franchises as a corporation, national banking association and corporation,
respectively, under the laws of the jurisdiction of its incorporation or
organization, and each will obtain and preserve its qualification to do business
as a foreign corporation 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 Loans and to perform its respective duties under
this Agreement.

            (b) The Depositor, the Servicer and the Special Servicer each may be
merged or consolidated with or into any Person (other than the Trustee), or
transfer all or substantially all of its assets to any Person (other than the
Trustee), in which case any Person resulting from any merger or consolidation to
which the Depositor, the Servicer or the Special Servicer shall be a party, or
any Person succeeding to the business of the Depositor, the Servicer or the
Special Servicer, shall be the successor of the Depositor, the Servicer and the
Special Servicer, as the case may be, hereunder, without the execution or filing
of any paper (other than an assumption agreement wherein the successor shall
agree to perform the obligations of and serve as the Depositor, the Servicer or
the Special Servicer, as the case may be, in accordance with the terms of this
Agreement) or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding; provided, however, that such merger,
consolidation or succession will not or has not resulted in a withdrawal,
downgrading or qualification of the then-current ratings of the Classes of
Certificates that have been so rated (as evidenced by a letter to such effect
from each Rating Agency).

            Section 6.03      Limitation on Liability of the Trustee,  the
Certificate  Administrator,  the  Depositor,  the  Servicer,  the  Special
Servicer and Others.

            (a) None of the Depositor, the Trustee, the Certificate
Administrator, the Custodian, the Servicer, the Special Servicer nor any of the
Affiliates, directors, members, managers, officers, employees or agents of any
of them shall be under any liability to the Trust Fund, the Underwriters, the
parties hereto or the Certificateholders for any action taken or for refraining
from the taking of any action in good faith pursuant to this Agreement, or for
errors in judgment; provided, however, that this provision shall not protect the
Depositor, the Trustee, the Certificate Administrator, the Custodian, the
Servicer, the Special Servicer or any such Person against any breach of
warranties or representations made herein or any liability which would otherwise
be imposed by reason of willful misfeasance, bad faith or negligence in the
performance of duties or by reason of negligent disregard of obligations and
duties hereunder. The Depositor, the Servicer, the Special Servicer, the
Trustee, the Certificate Administrator, the Custodian and any director, officer,
employee or agent of the Depositor, the Trustee, the Certificate Administrator,
the Custodian, the 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 Servicer, the Special Servicer, the Trustee, the
Certificate Administrator, the Custodian and any Affiliate, director, member,
manager, officer, employee or agent of any of the foregoing shall be indemnified
and held harmless by the Trust Fund against any loss, liability or expense
incurred in connection with any legal action relating to this Agreement, the
Loans or the Certificates, other than any loss, liability or expense: (i)
specifically required to be borne thereby pursuant to the terms hereof; (ii)
incurred in connection with any breach of a representation, warranty or covenant
made by it herein; (iii) incurred by reason of bad faith, willful misconduct or
negligence in the performance of its obligations or duties hereunder, or by
reason of negligent disregard of such obligations or duties or (iv) in the case
of the Depositor and any of its directors, officers, employees and agents,
incurred in connection with any violation by any of them of any state or federal
securities law.

            (b) None of the Depositor, the Trustee, the Certificate
Administrator, the Custodian, the Servicer or the Special Servicer shall be
under any obligation to appear in, prosecute or defend any legal or
administrative action, proceeding, hearing or examination that is not incidental
to its respective duties under this Agreement and which in its opinion may
involve it in any expense or liability; provided, however, that the Depositor,
the Servicer, the Special Servicer, the Trustee, the Custodian or the
Certificate Administrator may in its discretion undertake any such action,
proceeding, hearing or examination that it may deem necessary or desirable in
respect to this Agreement and 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, proceeding, hearing or examination and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust Fund, and the Depositor, the Servicer, the Special Servicer, the Trustee,
the Custodian and the Certificate Administrator shall be entitled to be
reimbursed therefor out of amounts attributable to the Loans on deposit in the
Collection Account as provided by Section 3.05(a).

            (c) Each of the Servicer and the Special Servicer agrees to
indemnify the Depositor, the Trustee, the Certificate Administrator, the
Custodian and the Trust Fund and each other and any Affiliate, director,
officer, employee or agent thereof, and hold them harmless, from and against any
and all claims, losses, penalties, fines, forfeitures, reasonable legal fees and
related out-of-pocket costs, judgments, and any other out-of-pocket costs,
liabilities, fees and expenses that any of them may sustain arising from or as a
result of any willful misfeasance, bad faith or negligence of the Servicer or
the Special Servicer, as the case may be, in the performance of its obligations
and duties under this Agreement or by reason of negligent disregard by the
Servicer or the Special Servicer, as the case may be, of its duties and
obligations hereunder or by reason of breach of any representations or
warranties made herein. The Servicer and the Special Servicer may consult with
counsel, and any written advice or Opinion of Counsel shall be full and complete
authorization and protection with respect to any action taken or suffered or
omitted by it hereunder in good faith in accordance with the Servicing Standard
and in accordance with such advice or Opinion of Counsel relating to (i) tax
matters, (ii) any amendment of this Agreement under Article X, (iii) the
defeasance of any Defeasance Loan or (iv) any matter involving legal proceeding
with a Borrower.

            The Trustee, the Certificate Administrator, the Custodian, the
Servicer, the Special Servicer or the Depositor, as the case may be, shall
immediately notify the Servicer or the Special Servicer, as applicable, if a
claim is made by a third party with respect to this Agreement or the Loans
entitling it to indemnification hereunder, whereupon the Servicer or the Special
Servicer, as the case may be, shall assume the defense of such claim and pay all
expenses in connection therewith, including counsel fees, and promptly pay,
discharge and satisfy any judgment or decree which may be entered against it or
them in respect of such claim. Any failure to so notify the Servicer or the
Special Servicer, as the case may be, shall not affect any rights any of the
foregoing Persons may have to indemnification under this Agreement or otherwise,
unless the Servicer's, or the Special Servicer's, as the case may be, defense of
such claim is materially prejudiced thereby. The indemnification provided herein
shall survive the termination of this Agreement and the termination or
resignation of the Servicer, the Trustee, the Certificate Administrator, the
Custodian and the Special Servicer.

            The Depositor agrees to indemnify the Servicer and the Special
Servicer and any Affiliate, director, officer, employee or agent thereof, and
hold them harmless, from and against any and all claims, losses, penalties,
fines, forfeitures, reasonable legal fees and related out-of-pocket costs,
judgments, and any other out-of-pocket costs, liabilities, fees and expenses
that any of them may sustain arising from or as a result of any breach of
representations and warranties or failure in the performance of the Depositor's
obligations and duties under this Agreement. The Servicer and the Special
Servicer shall immediately notify the Depositor if a claim is made by a third
party with respect to this Agreement or the Loans entitling it to
indemnification hereunder, whereupon the Depositor shall assume the defense of
such claim and pay all expenses in connection therewith, including counsel fees,
and promptly pay, discharge and satisfy any judgment or decree which may be
entered against it or them in respect of such claim. Any failure to so notify
the Depositor shall not affect any rights any of the foregoing Persons may have
to indemnification under this Agreement or otherwise, unless the Depositor's
defense of such claim is materially prejudiced thereby. The indemnification
provided herein shall survive the termination of this Agreement.

            (d) Any director, officer, employee, agent of the Servicer, Special
Servicer or any of their Affiliates shall not be personally liable for any error
of judgment made in good faith by any officer, unless it shall be proved that
the Servicer, the Special Servicer or such officer was negligent in ascertaining
the pertinent facts. No director, officer, employee or agent of the Servicer,
Special Servicer or any of their Affiliates shall be personally liable for any
action taken, suffered or omitted by it in good faith and believed by it to be
authorized or within the discretion, rights or powers conferred upon it by this
Agreement.

            Section 6.04      Depositor,  Servicer  and  Special  Servicer
Not to Resign.

            Subject to the provisions of Section 6.02, none of the Depositor,
the Servicer and the Special Servicer shall resign from their respective
obligations and duties hereby imposed on each of them except upon (a) a
determination that such party's duties hereunder are no longer permissible under
applicable law or (b) in the case of the Servicer or Special Servicer, upon the
appointment of, and the acceptance of such appointment by, a successor Servicer
or Special Servicer, as applicable and receipt by the Trustee of written
confirmation from each applicable Rating Agency that such resignation and
appointment will not cause such Rating Agency to downgrade, withdraw or qualify
any of then-current ratings assigned by such Rating Agency to any Class of
Certificates. Any such determination permitting the resignation of the
Depositor, the Servicer or the Special Servicer pursuant to above clause (a)
above shall be evidenced by an Opinion of Counsel (the cost of which, together
with any other expenses of such resignation, shall be at the expense of the
resigning party) to such effect delivered to the Trustee. No such resignation by
the Servicer or the Special Servicer shall become effective until the Trustee or
a successor Servicer shall have assumed the Servicer's or Special Servicer's, as
applicable, responsibilities and obligations in accordance with Section 7.02.

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

            The Depositor may, but is not obligated to, enforce the obligations
of the 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
Servicer and the Special Servicer hereunder or exercise the rights of the
Servicer or Special Servicer, as applicable, hereunder; provided, however, that
the Servicer and the Special Servicer shall not be relieved of any of their
respective obligations hereunder by virtue of such performance by the Depositor
or its designee. The Depositor shall not have any responsibility or liability
for any action or failure to act by the Servicer or the Special Servicer and is
not obligated to supervise the performance of the Servicer or the Special
Servicer under this Agreement or otherwise.

      or 15-day period, as applicable, the Servicer or the Special Servicer, as

      the Special Servicer, the Depositor and the Trustee by the Holders of
      Certificates of any Class evidencing, as to such Class, Percentage
      Interests aggregating not less than 25%; or

               (v) a decree or order of a court or agency or supervisory

      marshaling of assets and liabilities or similar proceedings, or for the
      winding-up or liquidation of its affairs, shall have been entered against
      the Servicer or the Special Servicer and such decree or order shall have
      remained in force undischarged or unstayed for a period of 60 days; or

               (vi) the Servicer or the Special Servicer shall consent to the

      all of its property; or

               (vii) the 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

               (viii) the Trustee shall have received and forwarded to the
      Servicer and the Special Servicer, as applicable, written notice from any
      Rating Agency that the continuation of the Servicer or Special Servicer in
      such capacity, has resulted, or would result, in and of itself, in a
      downgrade, qualification or withdrawal of any rating then-assigned to any
      Class of Certificates by such Rating Agency if the Servicer or Special
      Servicer, as the case may be, is not replaced (or with respect to Moody's,
      the Certificates are placed on watch for downgrade, citing servicing
      concerns), and the Trustee shall not have received subsequent notice from
      such Rating Agency (within 30 days) indicating that no such downgrade,
      qualification or withdrawal will result (or that, if it has resulted, it
      will be rescinded); or

               (ix) the Servicer or the Special Servicer shall have failed to
      satisfy the covenant set forth in Section 3.23(b) or Section 3.24(b), as
      applicable.

            (b) If any Event of Default with respect to the Servicer or the
Special Servicer (in either case, for purposes of this Section 7.01(b), the
"Defaulting Party") shall occur and be continuing, then, and in each and every
such case, so long as such Event of Default shall not have been remedied, the
Trustee may, and at the written direction of the Holders of Certificates
entitled to at least 51% of the Voting Rights and with respect to an Event of
Default pursuant to Section 7.01(a)(viii), shall, terminate, by notice in
writing to the Defaulting Party (a "Termination Notice"), with a copy of such
notice to the Depositor and the Certificate Registrar, all of the rights and
obligations of the Defaulting Party under this Agreement and in and to the Loans
and the proceeds thereof; provided, however, that the Defaulting Party shall be
entitled to the payment of accrued and unpaid compensation and reimbursement
through the date of such termination as provided for under this Agreement for
services rendered and expenses incurred.

            From and after the receipt by the Defaulting Party of such written
notice, 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 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 Loans and related documents, or otherwise.

            The Servicer and 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 20 Business Days after its receipt of the notice of termination)
provide the Trustee with all documents and records requested by it to enable the
Trustee to assume the Servicer's or the Special Servicer's, as the case may be,
functions hereunder, and shall cooperate with the Trustee in effecting the
termination of the Servicer's or the Special Servicer's, as the case may be,
responsibilities and rights hereunder, including, without limitation, the
transfer within five Business Days to the Trustee for administration by it of
all cash amounts which shall at the time be or should have been credited by the
Servicer to the Collection Account, or any Servicing Account (if it is the
Defaulting Party) or by the Special Servicer to the REO Account (if it is the
Defaulting Party) or thereafter be received with respect to the Loans or any REO
Property (provided, however, that the 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 (in the case of
the Servicer) or otherwise, and it and its directors, officers, employees and
agents shall continue to be entitled to the benefits of Section 6.03
notwithstanding any such termination).

            (c) The Holder or Holders of more than 50% of the aggregate
Certificate Balance of the Controlling Class shall be entitled to terminate the
rights and obligations of the Special Servicer under this Agreement, with or
without cause, upon 10 Business Days notice to the Special Servicer, the
Servicer and the Trustee, and to appoint a successor Special Servicer; provided,
however, that (i) such successor will meet the requirements set forth in Section
7.02 and (ii) as evidenced in writing by each of the Rating Agencies, the
proposed successor of such Special Servicer will not, in and of itself, result
in a downgrading, withdrawal or qualification of the then-current ratings
provided by the Rating Agencies in respect to any Class of then outstanding
Certificates that is rated. No penalty or fee shall be payable to the Special
Servicer with respect to any termination pursuant to this Section 7.01(c).

            (d) The Servicer and Special Servicer shall, from time to time, take
all such actions as are required by them in order to maintain their respective
status as an approved servicer and special servicer, as applicable and as
pertains to this transaction, with each of the Rating Agencies.

            (e) If the Servicer receives a Termination Notice pursuant to
Section 7.01(b) relating solely to an Event of Default set forth in Section
7.01(a)(viii), and if the Servicer provides the Certificate Administrator with
the appropriate "request for proposal" materials within five Business Days after
receipt of such written notice of termination, then the Certificate
Administrator shall promptly thereafter (using such "request for proposal"
materials provided by the Servicer) solicit good faith bids for the rights to
service the Loans under this Agreement from at least three Qualified Bidders or,
if three Qualified Bidders cannot be located, then from as many Persons as the
Certificate Administrator can determine are Qualified Bidders. At the
Certificate Administrator's request, the Servicer shall supply the Certificate
Administrator with the names of Persons from whom to solicit such bids. In no
event shall the Certificate Administrator be responsible if less than three
Qualified Bidders submit bids for the right to service the Loans under this
Agreement.

            Each bid proposal shall require any Successful Bidder (as defined
below), as a condition of its bid, to enter into this Agreement as successor
Servicer and to agree to be bound by the terms hereof, not later than 30 days
after termination of the Servicer hereunder. The Certificate Administrator shall
select the Qualified Bidder with the highest cash bid (or such other Qualified
Bidder as the terminated Servicer may direct) (the "Successful Bidder") to act
as successor Servicer hereunder. The Certificate Administrator shall direct the
Successful Bidder to enter into this Agreement as successor Servicer pursuant to
the terms hereof, and, in connection therewith to deliver the amount of the
Successful Bidder's cash bid to the Certificate Administrator by wire transfer
of immediately available funds to an account specified by the Certificate
Administrator no later than 10:00 am New York City time on the date specified
for the assignment and assumption of the servicing rights hereunder.

            Upon the assignment and acceptance of the servicing rights hereunder
to and by the Successful Bidder and receipt of such cash bid, the Certificate
Administrator shall remit or cause to be remitted to the terminated Servicer the
amount of such cash bid received from the Successful Bidder (net of
out-of-pocket expenses incurred by the Certificate Administrator in connection
with obtaining such bid and transferring servicing) by wire transfer of
immediately available funds to an account specified by the terminated Servicer
no later than 1:00 p.m. New York City time on the date specified for the
assignment and assumption of the servicing rights hereunder.

            If the Successful Bidder has not entered into this Agreement as
successor Servicer within 30 days after the termination of the Servicer
hereunder or no Successful Bidder was identified within such 30-day period, the
Certificate Administrator shall have no further obligations under this Section
7.01(e).

            Section 7.02      Trustee to Act; Appointment of Successor.

            On and after the time the Servicer or the Special Servicer, as the
case may be, either resigns pursuant to the first sentence of Section 6.04 or
receives a notice of termination for cause pursuant to Section 7.01(a), and
provided that no acceptable successor has been appointed and subject to Section
7.01(e), the Trustee shall be and become the successor to the Servicer or
Special Servicer, as the case may be, in all respects in its capacity as
Servicer or Special Servicer under this Agreement and the transactions set forth
or provided for herein and shall be subject to all the responsibilities, duties,
liabilities and limitations on liability relating thereto and that arise
thereafter placed on or for the benefit of the Servicer or Special Servicer by
the terms and provisions hereof; provided, however, that any failure to perform
such duties or responsibilities caused by the terminated party's failure under
Section 7.01 to provide information or moneys required hereunder shall not be
considered a default by such successor hereunder.

            The appointment of a successor Servicer shall not affect any
liability of the predecessor Servicer which may have arisen prior to its
termination as Servicer, and the appointment of a successor Special Servicer
shall not affect any liability of the predecessor Special Servicer which may
have arisen prior to its termination as Special Servicer. The Trustee in its
capacity as successor to the Servicer or the Special Servicer, as the case may
be, shall not be liable for any of the representations and warranties of the
Servicer or the Special Servicer, respectively, herein or in any related
document or agreement, for any acts or omissions of the predecessor Servicer or
Special Servicer or for any losses incurred by the Servicer pursuant to Section
3.06 hereunder, nor shall the Trustee be required to purchase any Loan
hereunder.

            As compensation therefor, the Trustee as successor Servicer shall be
entitled to the Servicing Fees and all fees relating to the Loans which the
Servicer would have been entitled to if the Servicer had continued to act
hereunder (other than the Assignable Primary Servicing Fee), including but not
limited to any income or other benefit from any Permitted Investment pursuant to
Section 3.06, and as successor to the Special Servicer shall be entitled to the
Special Servicing Fees to which the Special Servicer would have been entitled if
the Special Servicer had continued to act hereunder. Should the Trustee succeed
to the capacity of the Servicer or the Special Servicer, the Trustee shall be
afforded the same standard of care and liability as the Servicer or the Special
Servicer, as applicable, hereunder notwithstanding anything in Section 8.01 to
the contrary, but only with respect to actions taken by it in its role as
successor Servicer or successor Special Servicer, as the case may be, and not
with respect to its role as Trustee hereunder. The Trustee shall not be entitled
to receive the Assignable Primary Servicing Fees.

            Notwithstanding the above and subject to Section 7.01(e), the
Trustee may, if it shall be unwilling to act as successor to the Servicer or
Special Servicer, or shall, if it is unable to so act, or if the Trustee is not
approved as a servicer or special servicer, as applicable, by each Rating
Agency, or if the Holders of Certificates entitled to at least 51% of the Voting
Rights so request in writing to the Trustee, promptly appoint, or petition a
court of competent jurisdiction to appoint, any established mortgage loan
servicing institution which meets the criteria set forth herein, as the
successor to the Servicer or the Special Servicer, as applicable, hereunder in
the assumption of all or any part of the responsibilities, duties or liabilities
of the Servicer or Special Servicer hereunder. No appointment of a successor to
the Servicer or the Special Servicer under this Section 7.02 shall be effective
(i) until each of the Rating Agencies shall have confirmed in writing that its
then-current rating (if any) of each Class of Certificates will not be qualified
(as applicable), downgraded or withdrawn by reason thereof and (ii) until the
assumption in writing by the successor to the Servicer or the Special Servicer
of all its responsibilities, duties and liabilities hereunder that arise
thereafter. Pending appointment of a successor to the Servicer or the Special
Servicer hereunder, unless the Trustee shall be prohibited by law from so
acting, the Trustee shall act in such capacity as herein above provided.

            In connection with such appointment and assumption of a successor to
the Servicer or Special Servicer as described herein, the Trustee may make such
arrangements for the compensation of such successor out of payments on Loans as
it and such successor shall agree; provided, however, that no such compensation
with respect to a successor Servicer or successor Special Servicer, as the case
may be, shall be in excess of that permitted the terminated Servicer or Special
Servicer, as the case may be, hereunder and, in the case of a successor
appointed pursuant to the provision of Section 7.01(e), such compensation shall
not be less than that paid to the terminated Servicer, in each case excluding
the Assignable Primary Servicing Fee; provided, further, that if no successor
can be obtained for such compensation, then, subject to approval by the Rating
Agencies, additional amounts shall be paid to such successor and such amounts in
excess of that permitted the terminated Servicer or Special Servicer, as the
case may be, shall be treated as Collateral Support Deficit. The Trustee, the
Servicer or the Special Servicer (whichever is not the terminated party) and
such successor shall take such action, consistent with this Agreement, as shall
be necessary to effectuate any such succession. Any costs and expenses
associated with the transfer of the servicing function (other than with respect
to a termination without cause) under this Agreement shall be borne by the
predecessor Servicer or Special Servicer.

            Section 7.03      Notification to Certificateholders.

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

            (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) 5 days after the Trustee would be deemed
to have notice of the occurrence of such an event in accordance with Section
8.02(vii), the Trustee shall transmit by mail to the Depositor and all
Certificateholders notice of such occurrence, unless such default shall have
been cured.

            Section 7.04      Waiver of Events of Default.

            The Holders of Certificates representing at least 66 2/3% (or 100%
in the case of an Event of Default pursuant to Section 7.01(a)(viii)) of the
Voting Rights allocated to each Class of Certificates affected by any Event of
Default hereunder may waive such Event of Default within 20 days of the receipt
of notice from the Trustee of the occurrence of such Event of Default; provided,
however, that an Event of Default under clause (i) of Section 7.01(a) may not be
waived. Upon any such waiver of an Event of Default and reimbursement by the
Servicer to the Trustee and the Certificate Administrator of all costs and
expenses incurred by it in connection with such Event of Default and prior to
its waiver, 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 the same Voting Rights with
respect to the matters described above as they would if any other Person held
such Certificates.

            Section 7.05      Trustee Advances.

            If the Servicer fails to fulfill its obligations hereunder to make
any Advances, the Trustee shall perform such obligations (x) within one Business
Day of such failure by the Servicer with respect to Servicing Advances to the
extent a Responsible Officer of the Trustee has been notified in writing of such
failure with respect to such Servicing Advances and (y) by 1:00 p.m., New York
City time, on the related Distribution Date with respect to P&I Advances. With
respect to any such Advance made by the Trustee, the Trustee shall succeed to
all of the Servicer's rights with respect to Advances hereunder, including,
without limitation, the Servicer's rights of reimbursement and interest on each
Advance at the Reimbursement Rate, and rights to determine that a proposed
Advance is a Nonrecoverable P&I Advance or Servicing Advance, as the case may
be, (without regard to any impairment of any such rights of reimbursement caused
by such Servicer's default in its obligations hereunder); provided, however,
that if Advances made by both the Trustee and the Servicer shall at any time be
outstanding, or any interest on any Advance shall be accrued and unpaid, all
amounts available to repay such Advances and the interest thereon hereunder
shall be applied entirely to the Advances outstanding to the Trustee, until such
Advances shall have been repaid in full, together with all interest accrued
thereon, prior to reimbursement of the Servicer for such Advances. The Trustee
shall be entitled to conclusively rely on any notice given with respect to a
Nonrecoverable Advance hereunder.

                                  ARTICLE VIII

           CONCERNING THE TRUSTEE AND CERTIFICATE ADMINISTRATOR

            Section 8.01      Duties of Trustee.

            (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiving 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, then
(subject to Section 8.02(vii) below) 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 which 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. If any
such instrument is found not to conform to the requirements of this Agreement in
a material manner, the Trustee shall make a request to the responsible party 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, the 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 willful 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 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;

               (iii) The Trustee shall not be 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 (unless a
      higher percentage of Voting Rights is required for such action); and

               (iv) Subject to the other provisions of this Agreement and
      without limiting the generality of this Section 8.01, the Trustee shall
      have no duty except in the capacity as successor Servicer or successor
      Special Servicer (A) to see to any recording, filing or depositing of this
      Agreement or any agreement referred to herein or any financing statement
      or continuation statement evidencing a security interest, or to see to the
      maintenance of any such recording or filing or depositing or to any
      re-recording, refiling or redepositing of any thereof, (B) to see to any
      insurance, and (C) to confirm or verify the contents of any reports or
      certificates of the Servicer or Special Servicer delivered to the Trustee
      pursuant to this Agreement reasonably believed by the Trustee to be
      genuine and to have been signed or presented by the proper party or
      parties.

            Section 8.02      Certain Matters Affecting the Trustee.

            Except as otherwise provided in Section 8.01:

               (i) 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;

               (ii) 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;

               (iii) 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 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, in the Trustee's reasonable opinion,
      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 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; nothing contained herein shall,
      however, 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;

               (iv) The Trustee shall not be 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;

               (v) 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 50% 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. The reasonable expense of every such reasonable examination shall
      be paid by the Servicer or, if paid by the Trustee, shall be repaid by the
      Servicer upon demand;

               (vi) 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 appointment of such
      agents or attorneys shall not relieve the Trustee of its duties or
      obligations hereunder;

               (vii) For all purposes under this Agreement, the Trustee shall
      not be required to take any action with respect to, or be deemed to have
      notice or knowledge of any default or Event of Default unless a
      Responsible Officer of the Trustee has actual knowledge thereof or shall
      have received written notice thereof. In the absence of receipt of such
      notice and such actual knowledge otherwise obtained, the Trustee may
      conclusively assume that there is no default or Event of Default;

               (viii) The Trustee shall not be responsible for any act or
      omission of the Servicer, the Special Servicer or the Directing
      Certificateholder (unless the Trustee is acting as Servicer, Special
      Servicer or the Directing Certificateholder, as the case may be) or of the
      Depositor; and

               (ix) The Trustee shall not be required to give any bond or surety
      in respect of the execution of the Trust Fund created hereby or the power
      granted hereunder.

            Section 8.03    Trustee Not Liable for Validity or Sufficiency of
Certificates or Loans.

            The recitals contained herein and in the Certificates, other than
the acknowledgments of the Trustee in Section 2.04, shall be taken as the
statements of the Depositor, the Servicer or the Special Servicer, as the case
may be, and the Trustee assumes no responsibility for their correctness. The
Trustee does not make any representations as to the validity or sufficiency of
this Agreement or of any Certificate or of any Loan or related document. The
Trustee 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 Loans to the Trust Fund, or any funds deposited in or
withdrawn from the Collection Account or any other account by or on behalf of
the Depositor, the Servicer, the Special Servicer or the Trustee. 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, the Servicer or the Special Servicer, and accepted
by the Trustee, in good faith, pursuant to this Agreement.

            Section 8.04      Trustee May Own Certificates.

            The Trustee in its individual capacity and not as Trustee, may
become the owner or pledgee of Certificates, and may deal with the Depositor,
the Servicer, the Special Servicer, the Certificate Administrator, the
Custodian, the Initial Purchaser and the Underwriters in banking transactions,
with the same rights it would have if it were not Trustee.

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

            (a) As compensation for the performance of its duties, the Trustee
shall be paid the Trustee Fee, equal to one month's interest at the Trustee Fee
Rate on the Stated Principal Balance of each Loan or REO Loan, which shall cover
recurring and otherwise reasonably anticipated expenses of the Trustee. The
Trustee Fee (which shall not be limited to any provision of law in regard to the
compensation of a trustee of an express trust) shall constitute the Trustee's
sole form of compensation for all services rendered by it 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.

            (b) As compensation for the performance of its duties, the
Certificate Administrator shall be paid the Certificate Administrator Fee, equal
to one month's interest at the Certificate Administrator Fee Rate on the Stated
Principal Balance of each Loan or REO Loan, which shall cover recurring and
otherwise reasonably anticipated expenses of the Certificate Administrator. The
Certificate Administrator Fee (which shall not be limited to any provision of
law in regard to the compensation of a Certificate Administrator of an express
trust) shall constitute the Certificate Administrator's sole form of
compensation for all services rendered by it in the execution of the trusts
hereby created and in the exercise and performance of any of the powers and
duties of the Certificate Administrator hereunder.

            (c) The Trustee and the Certificate Administrator shall each be paid
or reimbursed by the Trust Fund upon its request for all reasonable expenses and
disbursements incurred by the Trustee or the Certificate Administrator pursuant
to and in accordance with any of the provisions of this Agreement (including the
reasonable compensation and the expenses and disbursements of its counsel and of
all persons not regularly in its employ) to the extent such payments are
"unanticipated expenses incurred by the REMIC" within the meaning of Treasury
Regulations Section 1.860G-1(b)(iii) except any such expense, disbursement or
advance as may arise from its negligence, bad faith or willful misconduct;
provided, however, that subject to Section 8.02(iii) and 8.14(b), respectively,
neither the Trustee nor the Certificate Administrator shall refuse to perform
any of its duties hereunder solely as a result of the failure to be paid the
Trustee Fee, the Certificate Administrator Fee or the Trustee's or the
Certificate Administrator's expenses.

            (d) The Trustee and any Affiliate, director, officer, employee or
agent of the Trustee shall be indemnified and held harmless by the Trust Fund
against any loss, liability or expense (including, without limitation, costs and
expenses of litigation, and of investigation, counsel fees, damages, judgments
and amounts paid in settlement, and expenses incurred in becoming successor
servicer, to the extent not otherwise paid hereunder) arising out of, or
incurred in connection with, this Agreement, the Loans, the Certificates or any
act or omission of the Trustee relating to the exercise and performance of any
of the powers and duties of the Trustee hereunder; provided, however, that
neither the Trustee nor any of the other above specified Persons shall be
entitled to indemnification pursuant to this Section 8.05(d) for (i) allocable
overhead, (ii) routine expenses or disbursements incurred or made by or on
behalf of the Trustee in the normal course of the Trustee's performing its
duties in accordance with any of the provisions hereof, which are not
"unanticipated expenses of the REMIC" within the meaning of Treasury Regulations
Section 1.860G-1(b)(3)(ii), (iii) any expense or liability specifically required
to be borne thereby pursuant to the terms hereof or (iv) 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 negligent disregard of such obligations or duties, or as may arise from a
breach of any representation, warranty or covenant of the Trustee made herein.
The provisions of this Section 8.05(d) shall survive any resignation or removal
of the Trustee and appointment of a successor thereto.

            (e) The Certificate Administrator and any Affiliate, director,
officer, employee or agent of the Certificate Administrator shall be indemnified
and held harmless by the Trust Fund against any loss, liability or expense
(including, without limitation, costs and expenses of litigation, and of
investigation, counsel fees, damages, judgments and amounts paid in settlement
to the extent not otherwise paid hereunder) arising out of, or incurred in
connection with, this Agreement, the Loans, the Certificates or any act or
omission of the Certificate Administrator relating to the exercise and
performance of any of the powers and duties of the Certificate Administrator
hereunder; provided, however, that neither the Certificate Administrator nor any
of the other above specified Persons shall be entitled to indemnification
pursuant to this Section 8.05(e) for (i) allocable overhead, (ii) routine
expenses or disbursements incurred or made by or on behalf of the Certificate
Administrator in the normal course of the Certificate Administrator's performing
its duties in accordance with any of the provisions hereof, which are not
"unanticipated expenses of the REMIC" within the meaning of Treasury Regulations
Section 1.860G-1(b)(3)(ii), (iii) any expense or liability specifically required
to be borne thereby pursuant to the terms hereof or (iv) any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of the Certificate Administrator's obligations and duties
hereunder, or by reason of negligent disregard of such obligations or duties, or
as may arise from a breach of any representation, warranty or covenant of the
Certificate Administrator made herein. The provisions of this Section 8.05(e)
shall survive any resignation or removal of the Certificate Administrator and
appointment of a successor thereto.

            Section 8.06      Eligibility Requirements for Trustee.

            The Trustee hereunder shall at all times be, and will be required to
resign if it fails to be, (i) a corporation, national bank or national banking
association, organized and doing business under the laws of any state or the
United States of America, authorized under such laws to exercise corporate trust
powers and to accept the trust conferred under this Agreement, having a combined
capital and surplus of at least $50,000,000 and subject to supervision or
examination by federal or state authority and shall not be an Affiliate of the
Servicer or the Special Servicer (except during any period when the Trustee is
acting as, or has become successor to, the Servicer or the Special Servicer, as
the case may be, pursuant to Section 7.02), (ii) an institution insured by the
Federal Deposit Insurance Corporation and (iii) an institution whose long-term
senior unsecured debt is rated "AA-" by DCR (or, if not rated by DCR, an
equivalent rating from at least two other NRSROs), "AA-" by Fitch and "Aa2" by
Moody's (or such entity as would not, as evidenced in writing by such Rating
Agency, result in the qualification (as applicable), downgrading or withdrawal
of any of then-current ratings then assigned thereby to the Certificates).

            If such corporation, national bank or national banking association
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 corporation,
national bank or national banking association shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. In the event the place of business from which the Trustee administers
either REMIC created hereunder is in a state or local jurisdiction that imposes
a tax on the Trust Fund on the net income of a REMIC (other than a tax
corresponding to a tax imposed under the REMIC Provisions), the Trustee shall
elect either to (i) resign immediately in the manner and with the effect
specified in Section 8.07, (ii) pay such tax at no expense to the Trust Fund or
(iii) administer each REMIC created hereunder from a state and local
jurisdiction that does not impose such a tax.

            Section 8.07      Resignation and Removal of the 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
Servicer, the Special Servicer and to all Certificateholders. Upon receiving
such notice of resignation, the Depositor shall promptly appoint a successor
trustee acceptable to the Servicer 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 Servicer, the Special Servicer and the Certificateholders by
the Depositor. 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. The resigning Trustee
shall be responsible for the payment of all reasonable expenses incurred in
connection with such resignation and discharge and 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 or if the Depositor has received
notice from the Rating Agencies that failure to remove the Trustee will result
in a downgrade or withdrawal of the then-current rating assigned to any Class of
Certificates, and shall fail to resign after written request therefor by the
Depositor or the 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, then the Depositor may remove
the Trustee and appoint a successor trustee acceptable to the Servicer and the
Rating Agencies 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 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
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 Servicer, one complete set to the Trustee so removed
and one complete set to the successor so appointed. A copy of such instrument
shall be delivered to the Depositor, the Special Servicer and the remaining
Certificateholders by the Servicer. The Trustee shall be reimbursed for all
costs and expenses incurred by it in connection with such removal within 30 days
of demand therefor from amounts on deposit in the Lower-Tier Distribution
Account (provided the Trustee is removed without cause).

            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.

            Within 30 days following any succession of the Trustee under this
Agreement, the predecessor Trustee shall be paid all accrued and unpaid
compensation and reimbursement as provided for under this Agreement for services
rendered and expenses incurred. No Trustee shall be liable for any action or
omission of any successor Trustee.

            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 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 the Custodian, which Custodian shall become the agent of
the successor Trustee), and the Depositor, the Servicer, the Special Servicer,
the Certificate Administrator 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.

            (c) Upon acceptance of appointment by a successor Trustee as
provided in this Section 8.08, the Servicer shall mail notice of the succession
of such Trustee hereunder to the Depositor and the Certificateholders. If the
Servicer fails to mail such notice within 10 days after acceptance of
appointment by the successor Trustee, such successor Trustee shall cause such
notice to be mailed at the expense of the Servicer.

            Section 8.09      Merger or Consolidation of Trustee.

            Any Person into which the Trustee may be merged or converted or with
which it may be consolidated or any Person resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any Person succeeding
to all or substantially all of the corporate trust business of the Trustee,
shall be the successor of the Trustee, hereunder; provided, that, in the case of
the Trustee, such successor Person shall be eligible under the provisions of
Section 8.06, 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. The Trustee will provide notice of such event to the Servicer,
the Special Servicer, the Depositor and the Rating Agencies.

            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 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 Servicer and
the Trustee may consider necessary or desirable. If the 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 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 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 die, 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 Custodian.

            The Certificate Administrator is hereby appointed Custodian to hold
all of the Mortgage Files as agent for the Trustee. The Custodian is, and any
successor Custodian shall be, a depository institution subject to supervision by
federal or state authority, has combined capital and surplus of at least
$15,000,000 and qualified to do business in the jurisdiction in which it holds
any Mortgage File. The Custodian is not, and any successor Custodian shall not,
be the Depositor or any Affiliate of the Depositor. The Custodian is subject to
the same obligations and standard of care as would be imposed on the Trustee
hereunder in connection with the retention of Mortgage Files directly by the
Trustee. The appointment of the Custodian does not relieve the Trustee from any
of its obligations hereunder, and the Trustee shall remain responsible for all
acts and omissions of the Custodian. The Custodian appointed hereunder must
maintain a fidelity bond and errors and omissions policy in an amount customary
for Custodians which serve in such capacity in commercial mortgage loan
securitization transactions.

            Section 8.12      Access to Certain Information.

            (a) On or prior to the date of the first sale of any Private
Certificate to an Independent third party, the Depositor shall provide to the
Trustee a copy of any private placement memorandum or other disclosure document
used by the Depositor or its Affiliate in connection with the offer and sale of
the Class of Certificates to which such Private Certificate relates. In
addition, if any such private placement memorandum or disclosure document is
revised, amended or supplemented at any time following the delivery thereof to
the Trustee, the Depositor promptly shall inform the Trustee of such event and
shall deliver to the Trustee a copy of the private placement memorandum or
disclosure document, as revised, amended or supplemented.

            The Trustee (or, with respect to the items described in clauses (F)
and (H) below, the Custodian) shall maintain at its offices primarily
responsible for administering the Trust Fund and shall, upon reasonable advance
written notice, make available during normal business hours for review by any
Holder of a Certificate, the Depositor, the Servicer, the Special Servicer, the
Directing Certificateholder, any Rating Agency or any other Person to whom the
Trustee or Custodian, as applicable, believes such disclosure is appropriate,
originals or copies of the following items to the extent such documents have
been delivered to the Trustee or Custodian, as applicable: (i) in the case of a
Holder or prospective transferee of a Private Certificate, any private placement
memorandum or other disclosure document relating to the Class of Certificates to
which such Private Certificate belongs, in the form most recently provided to
the Trustee and (ii) in all cases, (A) this Agreement and any amendments hereto
entered into pursuant to Section 10.01, (B) all statements required to be
delivered to Certificateholders of the relevant Class pursuant to Section 4.02
since the Closing Date, (C) all Officer's Certificates delivered to the Trustee
since the Closing Date pursuant to Section 3.13, (D) all accountants' reports
delivered to the Trustee since the Closing Date pursuant to Section 3.14, (E)
any and all notices, reports and Environmental Assessments delivered to the
Trustee with respect to any Mortgaged Property securing a Defaulted Loan as to
which the environmental testing contemplated by Section 3.09(c) revealed that
either of the conditions set forth in clauses (i) and (ii) of the first sentence
thereof was not satisfied (but only for so long as such Mortgaged Property or
the related Loan are part of the Trust Fund), (F) any and all modifications,
waivers and amendments of the terms of a Loan entered into by the Servicer or
the Special Servicer and delivered to the Custodian pursuant to Section 3.20
(but only for so long as the affected Loan is part of the Trust Fund), (G) any
and all Officer's Certificates delivered to the Trustee to support the
Servicer's determination that any P&I Advance or Servicing Advance was or, if
made, would be a Nonrecoverable P&I Advance or Nonrecoverable Servicing Advance,
as the case may be, (H) any and all of the Loan Documents contained in the
Mortgage File, (I) any and all Appraisals obtained pursuant to the definition of
"Appraisal Reduction" herein, (J) information regarding the occurrence of
Servicing Transfer Events as to the Loans and (K) any and all Sub-Servicing
Agreements and any amendments thereto and modifications thereof.

            Copies of any and all of the foregoing items will be available from
the Trustee or Custodian, as applicable, upon written request; provided,
however, that the Trustee and the Custodian shall be permitted to require
payment of a sum sufficient to cover the reasonable costs and expenses of
providing such copies, except in the case of copies provided to the Rating
Agencies, which shall be free of charge. In addition, without limiting the
generality of the foregoing, the Holder of any Class J, Class K, Class L, Class
M, Class N and Class O Certificate may upon written request from the Certificate
Administrator obtain a copy of any report (other than the Asset Status Report)
delivered to the Rating Agencies under this Agreement.

            (b) Notwithstanding anything to the contrary herein, in addition to
the reports and information made available and distributed pursuant to the terms
of this Agreement (including the information set forth in Section 8.12(a)), the
Servicer and the Certificate Administrator shall, in accordance with such
reasonable rules and procedures as each may adopt (which may include the
requirement that an agreement that provides that such information shall be used
solely for purposes of evaluating the investment characteristics of the
Certificates be executed), also make the reports available to Certificateholders
pursuant to Section 4.02, as well as certain additional information received by
the Servicer or the Certificate Administrator, as the case may be, to any
Certificateholder, the Underwriters, the Initial Purchaser, any Certificate
Owner or any prospective investor identified as such by a Certificate Owner or
the Underwriters, that requests such reports or information; provided that the
Servicer or the Certificate Administrator, as the case may be, shall be
permitted to require payment of a sum sufficient to cover the reasonable costs
and expenses of providing copies of such reports or information.

            (c) With respect to any information furnished by the Certificate
Administrator, the Custodian or the Servicer pursuant to this Section 8.12, the
Certificate Administrator, the Custodian or Servicer, as the case may be, shall
be entitled to indicate the source of such information and the Certificate
Administrator or Servicer, as applicable, may affix thereto any disclaimer it
deems appropriate in its discretion. The Certificate Administrator or the
Servicer, as applicable, shall notify Certificateholders of the availability of
any such information in any manner as it, in its sole discretion, may determine.
In connection with providing access to or copies of the items described in the
preceding paragraph, the Certificate Administrator, the Custodian or the
Servicer, as the case may be, may require (a) in the case of Certificate Owners,
a confirmation executed by the requesting Person substantially in form and
substance reasonably acceptable to the Servicer, the Custodian or Certificate
Administrator, as applicable, generally to the effect that such Person is a
beneficial holder of Certificates or an investment advisor representing such
Person and is requesting the information solely for use in evaluating such
Person's investment in the Certificates and will otherwise keep such information
confidential and (b) in the case of a prospective purchaser or an investment
advisor representing such Person, confirmation executed by the requesting Person
in form and substance reasonably acceptable to the Certificate Administrator,
the Custodian or the Servicer, as the case may be, generally to the effect that
such Person is a prospective purchaser of a Certificate or an interest therein
or an investment advisor representing such Person, and is requesting the
information solely for use in evaluating a possible investment in Certificates.
None of the Servicer, the Custodian, the Certificate Administrator or the
Trustee shall be liable for the dissemination of information in accordance with
this Agreement.

            Section 8.13      Representations,  Warranties  and  Covenants
of the Trustee and Certificate Administrator.

            (a) The Trustee hereby represents and warrants to the Depositor, the
Certificate Administrator, the Custodian, the Servicer and the Special Servicer
and for the benefit of the Certificateholders, as of the Closing Date, that:

               (i) The Trustee is a banking corporation, duly organized, validly
      existing and in good standing under the laws of New York;

               (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 the breach of, any
      material agreement or other instrument to which it is a party or which is
      applicable to it or any of its assets;

               (iii) The Trustee has the full power and authority 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 each of the other parties hereto, constitutes a valid, legal
      and binding obligation of the Trustee, enforceable against the Trustee in
      accordance with the terms hereof, 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 specifically 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 which 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;
      and

               (vii) No consent, approval, authorization or order of any court
      or governmental agency or body is required for the execution, delivery and
      performance by the Trustee, or compliance by the Trustee with, this
      Agreement or the consummation of the transactions contemplated by this
      Agreement, except for any consent, approval, authorization or order which
      has not been obtained or cannot be obtained prior to the actual
      performance by the Trustee of its obligations under this Agreement, and
      which, if not obtained would not have a materially adverse effect on the
      ability of the Trustee to perform its obligations hereunder.

            (b) The Trustee covenants that any custom-made software or hardware
designed or purchased or licensed by the Trustee and used by it in the course of
the operation or management of, or the compiling, reporting or generation of
data required of it by this Agreement will be capable of identifying correctly,
performing calculations and processing accurately such data after December 31,
1999. The Holders of Certificates entitled to at least 51% of the Voting Rights
may terminate the Trustee by notice in writing to the Depositor and the Trustee,
if the Trustee is in breach of the covenant set forth in this Section 8.13(b),
provided, however, the foregoing shall not limit any rights or remedies of the
Trust Fund, the Certificateholders or any other party hereto for a breach under
any other section of this Agreement that may arise out of the failure of the
Trustee to be year 2000 ready before January 1, 2000. The foregoing matters
extend and relate only to the internal functioning of the software and hardware
maintained by the Trustee, and the Trustee shall not be responsible for the
accuracy or integrity of any data or calculations provided to the Trustee by any
third party.

            (c) The Certificate Administrator hereby represents and warrants to
the Depositor, the Trustee, the Servicer and the Special Servicer and for the
benefit of the Certificateholders, as of the Closing Date, that:

               (i) The Certificate Administrator 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
      Certificate Administrator, and the performance and compliance with the
      terms of this Agreement by the Certificate Administrator, will not violate
      the Certificate Administrator's charter and by-laws or constitute a
      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 instrument to which it is a party or which is
      applicable to it or any of its assets;

               (iii) The Certificate Administrator has the full power and
      authority 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 each of the other parties hereto, constitutes a valid, legal
      and binding obligation of the Certificate Administrator, enforceable
      against the Certificate Administrator in accordance with the terms hereof,
      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 specifically and (b)
      general principles of equity, regardless of whether such enforcement is
      considered in a proceeding in equity or at law;

               (v) The Certificate Administrator 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 Certificate Administrator's
      good faith and reasonable judgment, is likely to affect materially and
      adversely either the ability of the Certificate Administrator to perform
      its obligations under this Agreement or the financial condition of the
      Certificate Administrator;

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

               (vii) No consent, approval, authorization or order of any court
      or governmental agency or body is required for the execution, delivery and
      performance by the Certificate Administrator, or compliance by the
      Certificate Administrator with, this Agreement or the consummation of the
      transactions contemplated by this Agreement, except for any consent,
      approval, authorization or order which has not been obtained or cannot be
      obtained prior to the actual performance by the Certificate Administrator
      of its obligations under this Agreement, and which, if not obtained would
      not have a materially adverse effect on the ability of the Certificate
      Administrator to perform its obligations hereunder.

            (d) The Certificate Administrator covenants that any custom-made
software or hardware designed or purchased or licensed by the Certificate
Administrator and used by it in the course of the operation or management of, or
the compiling, reporting or generation of data required by this Agreement will
be capable of identifying correctly, performing calculations and processing
accurately such data with respect to dates after December 31, 1999.

            The Holders of Certificates entitled to at least 51% of the Voting
Rights may terminate the Certificate Administrator by notice in writing to the
Depositor and the Certificate Administrator, if the Certificate Administrator is
in breach of the covenant set forth in this Section 8.13(d), provided, however,
the foregoing shall not limit any rights or remedies of the Trust Fund, the
Certificateholders or any other party hereto for a breach under any other
Section of this Agreement that may arise out of the failure of the Certificate
Administrator to be year 2000 ready before January 1, 2000. The foregoing
matters extend and relate only to the internal functioning of the software and
hardware maintained by the Certificate Administrator, and the Certificate
Administrator shall not be responsible for the accuracy or integrity of any data
or calculations provided to the Certificate Administrator by any third party.

            Section 8.14      Certain  Matters  Regarding the  Certificate
Administrator.

            (a) The Certificate Administrator is subject to the same obligations
and standard of care as would be imposed on the Trustee hereunder if the Trustee
were performing the duties of the Certificate Administrator. Further, the
Certificate Administrator is subject to the eligibility and other requirements
imposed on the Trustee under Sections 8.06 (except that the Certificate
Administrator may be rated "Aa3" by Moody's), 8.07, 8.08 and 8.09 of this
Agreement.

            (b) The Certificate Administrator 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 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.

                       TERMINATION; PURCHASE OF ARD LOANS

            Section 9.01      Termination  Upon  Repurchase or Liquidation
of All Loans.

            Subject to Section 9.02, the Trust Fund and the respective
obligations and responsibilities under this Agreement of the Depositor, the
Servicer, the Special Servicer, the Certificate Administrator and the Trustee
(other than the obligations of the Certificate Administrator to provide for and
make payments to Certificateholders as hereafter set forth) shall terminate upon
payment (or provision for payment) 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 earliest to occur of (i) the purchase by either
Mortgage Loan Seller, the Special Servicer, the Holders of the Controlling Class
or the Servicer of all the Loans and each REO Property remaining in the Trust
Fund at a price equal to (a) the sum of (1) the aggregate Purchase Price of all
the Loans (exclusive of REO Loans) included in the Trust Fund and (2) the
Appraised Value of each REO Property, if any, included in the Trust Fund (such
Appraisals in this subclause (2) to be conducted by an Appraiser selected and
mutually agreed upon by the Servicer and the Trustee, and approved by more than
50% of the Voting Rights of the Classes of Certificates then outstanding (other
than the Controlling Class if the Controlling Class is exercising such option
unless the Controlling Class is the only Class of Certificates then
outstanding)), minus (b) solely in the case where the Servicer is effecting such
purchase, the aggregate amount of unreimbursed Advances, together with any
interest accrued and payable to the Servicer in respect of such Advances in
accordance with Sections 3.03(d) and 4.03(d) and any unpaid Servicing Fees,
remaining outstanding (which items shall be deemed to have been paid or
reimbursed to the Servicer in connection with such purchase), (ii) the
Distribution Date in September 2041 and (iii) the final payment or other
liquidation (or any advance with respect thereto) of the last Loan or REO
Property remaining in the Trust Fund; provided, however, that in no event shall
the trust created hereby continue beyond the earlier of (i) the Rated Final
Distribution Date and (ii) 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's, living on the date hereof.

            The CSFB Mortgage Loan Seller may, at its option, elect to purchase
all of the Loans and each REO Property remaining in the Trust Fund as
contemplated by clause (i) of the preceding paragraph by giving written notice
to the Trustee and the other parties hereto within 60 days of the first
Distribution Date on which the aggregate Stated Principal Balances of the Loans
and any REO Loans remaining in the Trust Fund is less than 1.00% of the
aggregate Cut-off Date Principal Balance of the Loans set forth in the
Preliminary Statement. If the CSFB Mortgage Loan Seller does not exercise such
option within 60 days after it becomes exercisable by the CSFB Mortgage Loan
Seller, the MS Mortgage Loan Seller may notify the CSFB Mortgage Loan Seller,
the Special Servicer and the Trustee of its intention to exercise such option,
and if the CSFB Mortgage Loan Seller fails to exercise such option within ten
Business Days thereafter, the MS Mortgage Loan Seller shall be entitled to
exercise such option. If the MS Mortgage Loan Seller does not exercise such
option within 60 days after it becomes exercisable by the MS Mortgage Loan
Seller, the Special Servicer may notify the CSFB Mortgage Loan Seller, the MS
Mortgage Loan Seller and the Trustee of its intention to exercise such option,
and if the MS Mortgage Loan Seller fails to exercise such option within ten
Business Days thereafter, the Special Servicer shall be entitled to exercise
such option. If the Special Servicer does not exercise such option within 60
days after it becomes exercisable by the Special Servicer, the Holders of a
majority of the Percentage Interests in the Controlling Class may notify the
CSFB Mortgage Loan Seller, the MS Mortgage Loan Seller, the Special Servicer and
the Trustee of their intention to exercise such option and if none of the CSFB
Mortgage Loan Seller, the MS Mortgage Loan Seller or the Special Servicer
exercises such option within ten Business Days thereafter, such Holders of the
Controlling Class shall be entitled to exercise such option. If the Holders of a
majority of the Percentage Interests of the Controlling Class do not exercise
such option within 60 days after it becomes exercisable by them, the Servicer
may notify the CSFB Mortgage Loan Seller, the MS Mortgage Loan Seller, the
Special Servicer, the Holders of the Controlling Class and the Trustee of the
Servicer's intention to exercise such option, and if none of the CSFB Mortgage
Loan Seller, the MS Mortgage Loan Seller, the Special Servicer or the Holders of
a majority of the Percentage Interests in the Controlling Class exercise such
option within ten Business Days thereafter, the Servicer will be entitled to
exercise such option. Any purchaser pursuant to Section 9.01(a) of a Loan
serviced by a Primary Servicer shall be required to enter into a servicing
agreement with such Primary Servicer, as applicable, in the form of the related
"Prior Servicing Agreement" (as defined in the Primary Servicing Agreement) or
shall be required to pay such Primary Servicer the termination fee that would be
payable thereunder.

            If the CSFB Mortgage Loan Seller, the MS Mortgage Loan Seller, the
Special Servicer, the Holders of the Controlling Class or the Servicer purchases
all of the Loans and each REO Property remaining in the Trust Fund in accordance
with the preceding paragraph, the CSFB Mortgage Loan Seller, the MS Mortgage
Loan Seller, the Special Servicer, the Holders of the Controlling Class or the
Servicer, as applicable, shall deposit in the Lower-Tier 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 (exclusive of any
portion thereof payable to any Person other than the Certificateholders pursuant
to Section 3.05(a), which portion shall be deposited in the Collection Account).
In addition, the Servicer shall transfer to the Lower-Tier Distribution Account
all amounts required to be transferred thereto on such P&I Advance Date from the
Collection Account pursuant to the first paragraph of Section 3.04(b), together
with any other amounts on deposit in the Collection Account that would otherwise
be held for future distribution. Upon confirmation that such final deposits have
been made, the Custodian shall release or cause to be released to the CSFB
Mortgage Loan Seller, the MS Mortgage Loan Seller, the Special Servicer, the
Holders of the Controlling Class or the Servicer, as applicable, the Mortgage
Files for the remaining Loans, and the Trustee shall execute all assignments,
endorsements and other instruments furnished to it by the CSFB Mortgage Loan
Seller, the MS Mortgage Loan Seller, the Special Servicer, the Holders of the
Controlling Class or the Servicer, as applicable, as shall be necessary to
effectuate transfer of the Loans and REO Properties remaining in the Trust Fund
and its rights under the related Mortgage Loan Purchase Agreement.

            For purposes of this Section 9.01, the Directing Certificateholder,
with the consent of the Holders of the Controlling Class, shall act on behalf of
the Holders of the Controlling Class in purchasing the assets of the Trust Fund
and terminating the Trust.

            Notice of any termination pursuant to this Section 9.01 shall be
given promptly by the Trustee by letter to the Certificateholders and each
Rating Agency and, if not previously notified pursuant to this Section 9.01, to
the other parties hereto mailed (a) in the event such notice is given in
connection with the purchase of all of the Loans and each REO Property remaining
in the Trust Fund, 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 P&I Advance 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 Administrator or such
other location therein designated.

            After transferring the Lower-Tier Distribution Amount and the amount
of any Prepayment Premiums and Yield Maintenance Charges distributable pursuant
to Section 4.01(d) to the Upper-Tier Distribution Account pursuant to Section
3.04(b) and upon presentation and surrender of the Certificates by the
Certificateholders on the final Distribution Date, the Certificate Administrator
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 Upper-Tier Distribution Account that are
allocable to payments on the Class of Certificates so presented and surrendered.
Amounts transferred from the Lower-Tier Distribution Account to the Upper-Tier
Distribution Account as of the final Distribution Date shall be allocated for
the purposes, in the amounts and in accordance with the priority set forth in
Sections 4.01(a) and 4.01(e) and shall be distributed in termination and
liquidation of the Uncertificated Lower-Tier Interests and the Class LR
Certificates in accordance with Sections 4.01(b) and (d). Any funds not
distributed on such Distribution Date shall be set aside and held uninvested in
trust for the benefit of Certificateholders not presenting and surrendering
their Certificates in the aforesaid manner and shall be disposed of in
accordance with this Section 9.01 and Section 4.01(h).

            Anything in this Section 9.01 to the contrary notwithstanding, the
Holders of the Class V-1 and Class V-2 Certificates shall receive that portion
of the proceeds of a sale of the assets of the Trust Fund allocable to accrued
and unpaid Excess Interest.

            Section 9.02      Additional Termination Requirements.

            If the CSFB Mortgage Loan Seller, the MS Mortgage Loan Seller, the
Special Servicer, the Holders of the Controlling Class or the Servicer purchases
all of the Loans and each REO Property remaining in the Trust Fund as provided
in Section 9.01, the Trust Fund shall be terminated in accordance with the
following additional requirements, which meet the definition of a "qualified
liquidation" in Section 860F(a)(4) of the Code:

               (i) the Servicer shall specify the first day in the 90-day
      liquidation period in a statement attached to each of the Upper-Tier
      REMIC's, and the Lower-Tier REMIC's final Tax Return pursuant to Treasury
      Regulations Section 1.860F-1 and shall satisfy all requirements of a
      qualified liquidation under Section 860F of the Code and any regulations
      thereunder;

               (ii) during such 90-day liquidation period and at or prior to the
      time of the making of the final payment on the Certificates, the Trustee
      shall sell all of the assets of the Lower-Tier REMIC to the CSFB Mortgage
      Loan Seller, the MS Mortgage Loan Seller, the Special Servicer, the
      Holders of the Controlling Class or the Servicer, as the case may be, for
      cash; and

               (iii) immediately following the making of the final payment on
      the Uncertificated Lower-Tier Interests and the Certificates, the
      Certificate Administrator shall distribute or credit, or cause to be
      distributed or credited, to the Holders of the Class LR Certificates (in
      the case of the Lower-Tier REMIC) and the Class R Certificates (in the
      case of the Upper-Tier REMIC) all cash on hand (other than cash retained
      to meet claims), in the Trust Fund and each of the Lower-Tier REMIC and
      the Upper-Tier REMIC shall terminate at that time.

            Section 9.03      Purchase of ARD Loans.

            The Holder of a 100% Percentage Interest in the Class V-1
Certificates may purchase any ARD Loan which is a CSFB Loan and the Holder of a
100% Percentage Interest in the Class V-2 Certificates may purchase any ARD Loan
which is a MS Loan, in each case, for up to two months after its Anticipated
Repayment Date at a price equal to the sum of the following:

               (i) 100% of the outstanding principal balance of such Loan on
      such Anticipated Repayment Date or Maturity Date, as applicable (less any
      P&I Advances previously made on account of principal);

               (ii) all unpaid interest accrued on such principal balance of
      such Loan at the Mortgage Rate thereof, to the last day of the Interest
      Accrual Period preceding such Anticipated Repayment Date or Maturity Date,
      as applicable (less any P&I Advances previously made on account of
      interest);

               (iii) the aggregate amount of all unreimbursed Advances with
      respect to such Loan, with interest thereon at the Advance Rate, and
      unpaid Servicing Fees, Special Servicing Fees, Trustee Fees, Certificate
      Administrator Fees and Trust Fund expenses; and

               (iv) the amount of any expenses incurred by the Trust Fund in
      connection with such purchase;

provided, however, that any such purchase may be consummated only if the
applicable Holder, at its expense, provides the Trustee with an Opinion of
Counsel to the effect that such purchase (or such right to purchase) would not
cause (a) either REMIC created hereunder to fail to qualify as a REMIC under the
Code at any time that any Certificate is outstanding and (b) would not cause the
arrangement between the Trust and the Class V-1 or Class V-2 Certificateholders
to be other than a grantor trust for federal income tax purposes, and (i) an
Opinion of Counsel to the effect that such purchase would not result in a gain
which would be subject to the tax on net income derived from prohibited
transactions imposed by Code Section 860F(a)(1) or otherwise result in the
imposition of any other tax on either REMIC created hereunder under the REMIC
Provisions or (ii) an accountant's certification to the effect that such
purchase would not result in the realization of any net income to either REMIC
created hereunder.

            The proceeds of any such purchase hereunder shall be deposited in
the Collection Account and disbursed as provided herein.

                            MISCELLANEOUS PROVISIONS

            Section 10.01     Amendment.

            (a) This Agreement may be amended from time to time by the parties
hereto, without the consent of any of the Certificateholders:

               (i) to cure any ambiguity;

               (ii) to correct or supplement any provisions herein or therein,
      which may be inconsistent with any other provisions herein or therein or
      to correct any error;

               (iii) to modify, eliminate or add to any of its provisions to
      such extent as shall be necessary to maintain the qualification of either
      REMIC created hereunder as a REMIC at all times that any Certificate
      (other than the Class V-1 and Class V-2 Certificates) is outstanding or to
      avoid or minimize the risk of the imposition of any tax on the Trust Fund
      or either REMIC created hereunder pursuant to the Code that would be a
      claim against the Trust Fund or either REMIC created hereunder, provided
      that the Trustee has received an Opinion of Counsel to the effect that (a)
      such action is necessary or desirable to maintain such qualification or to
      avoid or minimize the risk of the imposition of any such tax, (b) such
      action will not adversely affect in any material respect the interests of
      any Certificateholder, and (c) such change shall not result in the
      withdrawal, downgrade or qualification of the then-current rating assigned
      to any Class of Certificates, as evidenced by a letter from each Rating
      Agency to such effect;

               (iv) to change the timing and/or nature of deposits into the
      Collection Account, the Distribution Accounts or REO Account or to change
      the name in which the Collection Account is maintained, provided that (a)
      the P&I Advance Date shall in no event be later than the related
      Distribution Date, (b) such change shall not, as evidenced by an Opinion
      of Counsel addressed to the Trustee, adversely affect in any material
      respect the interests of any Certificateholder and (c) such change shall
      not result in the withdrawal, downgrade or qualification of the
      then-current rating assigned to any Class of Certificates, as evidenced by
      a letter from each Rating Agency to such effect;

               (v) to  modify,   eliminate  or  add  to  the  provisions  of
      Section 5.02(d)  or any other provision hereof  restricting  transfer
      of the  Residual  Certificates  by  virtue  of their  being the REMIC
      "residual  interests," provided that (a) such change shall not result
      in the withdrawal,  downgrade or  qualification  of the  then-current
      rating  assigned  to any Class of  Certificates,  as  evidenced  by a
      letter from each Rating  Agency to such effect,  and (b) such  change
      shall not, as  evidenced  by an Opinion of Counsel  addressed  to the
      Trustee,  cause the Trust Fund,  either  REMIC  created  hereunder or
      any of the  Certificateholders  (other  than  the  Transferor)  to be
      subject to a federal  tax caused by a Transfer  to a Person that is a
      Disqualified  Organization or a Non-U.S.  Person or a Transfer from a
      Person other than a U.S. Person;

               (vi) to make any other provisions with respect to matters or
      questions arising under this Agreement which shall not be materially
      inconsistent with the provisions of this Agreement, provided that such
      action shall not, as evidenced by an Opinion of Counsel addressed to the
      Trustee, adversely affect in any material respect the interests of any
      Certificateholder not consenting thereto; and

               (vii) to amend or supplement any provision hereof to the extent
      necessary to maintain the then-current rating or ratings assigned to each
      Class of Certificates by each Rating Agency as confirmed in writing.

            (b) This Agreement may also be amended from time to time by the
parties hereto with the consent of the Holders of Certificates evidencing in the
aggregate not less than 66 2/3% of the Percentage Interests of each Class of
Certificates affected thereby 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 of such
Class; provided, however, that no such amendment shall:

               (i)  reduce in any manner the amount of, or delay the timing of,
      payments which are required to be distributed on any Certificate without
      the consent of the Holder of such Certificate; or

               (ii) reduce the aforesaid percentage of Certificates of any Class
      the Holders of which are required to consent to any such amendment, in any
      such case without the consent of the Holders of all Certificates of such
      Class then outstanding; or

               (iii) adversely affect the Voting Rights of any Class of
      Certificates without the consent of the Holders of all Certificates of
      such Class then outstanding; or

               (iv)  amend this Section 10.01.

            (c) Notwithstanding the foregoing, the Trustee will not be entitled
to consent to any amendment hereto without having first received an Opinion of
Counsel to the effect that such amendment or the exercise of any power granted
to the Servicer, the Depositor, the Special Servicer, the Trustee or any other
specified person in accordance with such amendment will not result in the
imposition of a tax on the Trust Fund, either REMIC created hereunder or cause
either REMIC created hereunder to fail to qualify as a REMIC.

            (d) Promptly after the execution of any such amendment, the Trustee
shall furnish a copy of such amendment to each Rating Agency and each
Certificateholder.

            (e) It shall not be necessary for the consent of Certificateholders
under this Section 10.01 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) The Trustee 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 10.01(a), (b) or (c) shall be borne by the Person seeking the related
amendment, except that if the Servicer or the Trustee requests any amendment of
this Agreement in furtherance of the rights and interests of Certificateholders,
the cost of any Opinion of Counsel required in connection therewith pursuant to
Section 10.01(a), (b) or (c) shall be payable out of the Collection Account.

            Section 10.02     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 Servicer at the expense of the Depositor on direction by the
Trustee, but only upon direction accompanied by an Opinion of Counsel (the cost
of which shall be paid by the Depositor) to the effect that such recordation
materially and beneficially affects the interests of the Certificateholders.

            (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 10.03     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 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 of any Class evidencing not less than
25% of the related Percentage Interests in such Class 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. The Trustee shall be under no
obligation to exercise any of the trusts or powers vested in it hereunder or to
institute, conduct or defend any litigation hereunder or in relation hereto at
the request, order or direction of any of the Holders of Certificates unless
such Holders have offered to the Trustee reasonable security against the costs,
expenses and liabilities which may be incurred therein or hereby.

            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 10.03(c), each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

            Section 10.04     Governing Law.

            This Agreement and the Certificates 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 parties hereunder shall be determined in accordance with such laws.

            Section 10.05     Notices.

            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

            Section 10.07     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, (i) 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 comprising the Trust Fund,
including without limitation, the Loans, all principal and interest received or
receivable with respect to the Loans (other than principal and interest payments
due and payable prior to the Cut-off Date and Principal Prepayments received
prior to the Cut-off Date), all amounts held from time to time in the Collection
Account, the Distribution Accounts and, if established, the REO Account, and all
reinvestment earnings on such amounts, and all of the Depositor's right, title
and interest in and to the proceeds of any title, hazard or other Insurance
Policies related to such Loans and (ii) this Agreement shall constitute a
security agreement under applicable law. This Section 10.07 shall constitute
notice to the Trustee pursuant to any of the requirements of the applicable UCC.

            Section 10.08     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. No
other person, including, without limitation, any Mortgagor, shall be entitled to
any benefit or equitable right, remedy or claim under this Agreement.

            Section 10.09     Article and Section Headings.

            The article and Section headings herein are for convenience of
reference only, and shall not limit or otherwise affect the meaning hereof.

               (iii) any event that would result in the voluntary or involuntary
      termination of any insurance of the accounts of the Trustee.

            (c) Each of the Servicer and the Special Servicer shall promptly

     FOR FEDERAL  INCOME TAX PURPOSES,  THIS  CERTIFICATE  REPRESENTS A "REGULAR
INTEREST" IN A "REAL  ESTATE  MORTGAGE  INVESTMENT  CONDUIT," AS THOSE TERMS ARE
DEFINED,  RESPECTIVELY,  IN SECTIONS 860G(a)(1) AND 860D OF THE INTERNAL REVENUE
CODE OF 1986, AS AMENDED.

     THIS  CERTIFICATE  DOES NOT  REPRESENT AN  OBLIGATION OF OR INTEREST IN THE
DEPOSITOR,  THE CSFB  MORTGAGE  LOAN SELLER,  THE MS MORTGAGE  LOAN SELLER,  THE
SERVICER,  THE SPECIAL SERVICER,  THE TRUSTEE, THE CERTIFICATE  ADMINISTRATOR OR
ANY OF THEIR RESPECTIVE AFFILIATES.  NEITHER THE CERTIFICATES NOR THE UNDERLYING
LOANS ARE INSURED OR GUARANTEED BY ANY GOVERNMENTAL AGENCY OR INSTRUMENTALITY.

     Unless and until it is  exchanged in whole or in part for  Certificates  in
definitive form, this  Certificate may not be transferred  except as a whole (i)
by The Depository Trust Company, a New York corporation  ("DTC") to a nominee of
DTC,  (ii) by a nominee of DTC to DTC or another  nominee of DTC or (iii) by DTC
or any such  nominee to a successor  depository  or a nominee of such  successor
depository.

     Unless this  Certificate  is presented by an authorized  representative  of
DTC, to the  Certificate  Registrar or its agent 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 certifies that CEDE & CO. (the  "Certificateholder") is the registered
owner of a  beneficial  ownership  interest  in a trust  (the  "Trust")  created
pursuant to a Pooling and  Servicing  Agreement,  dated as of October 11,  1999,
(the "Pooling and Servicing  Agreement") by and among Wells Fargo Bank, National
Association,  as servicer (the  "Servicer"),  Lennar Partners,  Inc., as special
servicer  ("Special  Servicer"),  The Chase  Manhattan  Bank,  as  trustee  (the
"Trustee"),  Credit Suisse First Boston Mortgage  Securities Corp., as depositor
(the  "Depositor")  and  Norwest  Bank  Minnesota,   National  Association,   as
certificate administrator and custodian (the "Certificate  Administrator").  All
capitalized  terms used herein and not otherwise  defined  herein shall have the
meanings  ascribed  thereto  in  the  Pooling  and  Servicing  Agreement.   This
Certificate  is described in the Pooling and  Servicing  Agreement and is issued
pursuant to and subject to the Pooling and Servicing Agreement. By acceptance of
this  Certificate,  each  Certificateholder  assents to and becomes bound by the
Pooling and Servicing Agreement.

     On each Distribution Date, the Certificate  Administrator  shall distribute
to the Person in whose name this  Certificate is registered on the last Business
Day of the month immediately preceding the month in which such Distribution Date
occurs (or with respect to the first  Distribution  Date, the Closing Date),  an
amount equal to the Percentage  Interest  represented by this Certificate of the
amount  required to be  distributed to the  Certificateholders  of this Class on
such  Distribution  Date  pursuant to Section 4.01 of the Pooling and  Servicing
Agreement.

     All distributions  (other than the final distribution) shall be made to the
Persons in whose name the  Certificates  are registered at the close of business
on each  Record  Date by wire  transfer of  immediately  available  funds to the
account of such  Certificateholder  at a bank or other entity having appropriate
facilities  therefor  if  such  Certificateholder  shall  have so  notified  the
Certificate  Administrator  in writing by no later than five Business Days prior
to the  Record  Date  immediately  prior  to such  Distribution  Date and is the
registered  Certificateholder  of Certificates of the Class  represented by this
Certificate  with an  initial  Certificate  Balance  equal  to or in  excess  of
$5,000,000;   and  in  all   other   cases  by  check   mailed   to  each   such
Certificateholder   at  such   Certificateholder's   address  appearing  in  the
Certificate  Register,  in either case without  presentation or surrender of any
Certificate  held  by  such  Certificateholder  or the  making  of any  notation
thereon.  Distributions  on the final  Distribution  Date with  respect  to this
Certificate,   however,   shall  require   presentment  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  Pooling and  Servicing  Agreement  permits,  with  certain  exceptions
therein provided,  the amendment thereof, and the modification of the rights and
obligations of the Depositor,  the Servicer,  the Special Servicer,  the Trustee
and  the   Certificate   Administrator   thereunder   and  the   rights  of  the
Certificateholders  thereunder,  at any time by the Depositor, the Servicer, the
Special Servicer, the Trustee and the Certificate Administrator with the consent
of the Holders of  Certificates  entitled to at least 66 2/3% of the  Percentage
Interests of each Class affected thereby. 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 Pooling and Servicing Agreement also
permits the amendment thereof, in certain circumstances, including any amendment
necessary to maintain the status of  designated  portions of the Trust Fund as a
REMIC, without the consent of the Holders of any of the Certificates.

     No  sale,  transfer  or  other  disposition  of this  Certificate  shall be
permitted  other than in accordance  with the  provisions of Section 5.02 of the
Pooling and Servicing Agreement.

     This Certificate does not represent an obligation of, or an interest in the
Servicer,  the Special Servicer,  the Depositor,  the Trustee or the Certificate
Administrator,  except to the extent  described  in the  Pooling  and  Servicing
Agreement,  or any Affiliate  thereof,  nor will this  Certificate be insured or
guaranteed by any governmental  agency.  This Certificate is limited in right of
payment to certain  collections on the Mortgage Loans, as more  specifically set
forth in the Pooling and Servicing Agreement.

     The Holder hereof,  by its acceptance of this  Certificate,  agrees to look
solely to the assets of the Trust Fund, as provided in the Pooling and Servicing
Agreement,  for  payment  hereunder  and that the  Trustee  and the  Certificate
Administrator in their individual capacities are not liable to the Holder hereof
for any amounts  payable  under this  Certificate  or the Pooling and  Servicing
Agreement.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement  and  is  qualified  in its  entirety  by the  Pooling  and  Servicing
Agreement.  Reference  is  made  to the  Pooling  and  Servicing  Agreement  for
information  with  respect  to the  interests,  rights,  benefits,  obligations,
proceeds and duties  evidenced  hereby and the rights,  duties and immunities of
the  Trustee  and the  Certificate  Administrator.  Copies  of the  Pooling  and
Servicing Agreement and all amendments thereto will be provided to a prospective
or  actual  Certificateholder,  upon  written  request  and,  at  the  Trustee's
discretion,  payment of a reasonable fee for any expenses, to the Trustee at 450

therein provided,  the amendment thereof, and the modification of the rights and
obligations of the Depositor,  the Servicer,  the Special Servicer,  the Trustee
and  the   Certificate   Administrator   thereunder   and  the   rights  of  the

Special Servicer, the Trustee and the Certificate Administrator with the consent
of the Holders of  Certificates  entitled to at least 66 2/3% of the  Percentage

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 Pooling and Servicing Agreement also
permits the amendment thereof, in certain circumstances, including any amendment
necessary to maintain the status of  designated  portions of the Trust Fund as a
REMIC, without the consent of the Holders of any of the Certificates.

permitted  other than in accordance  with the  provisions of Section 5.02 of the
Pooling and Servicing Agreement.

     This Certificate does not represent an obligation of, or an interest in the
Servicer,  the Special Servicer,  the Depositor,  the Trustee or the Certificate
Administrator,  except to the extent  described  in the  Pooling  and  Servicing
Agreement,  or any Affiliate  thereof,  nor will this  Certificate be insured or
guaranteed by any governmental  agency.  This Certificate is limited in right of
payment to certain  collections on the Mortgage Loans, as more  specifically set
forth in the Pooling and Servicing Agreement.

Agreement,  for  payment  hereunder  and that the  Trustee  and the  Certificate

for any amounts  payable  under this  Certificate  or the Pooling and  Servicing

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

     This certifies that CEDE & CO. (the  "Certificateholder") is the registered
owner of a  beneficial  ownership  interest  in a trust  (the  "Trust")  created

capitalized  terms used herein and not otherwise  defined  herein shall have the
meanings  ascribed  thereto  in  the  Pooling  and  Servicing  Agreement.   This
Certificate  is described in the Pooling and  Servicing  Agreement and is issued
pursuant to and subject to the Pooling and Servicing Agreement. By acceptance of
this  Certificate,  each  Certificateholder  assents to and becomes bound by the
Pooling and Servicing Agreement.

     On each Distribution Date, the Certificate  Administrator  shall distribute
to the Person in whose name this  Certificate is registered on the last Business
Day of the month immediately preceding the month in which such Distribution Date
occurs (or with respect to the first  Distribution  Date, the Closing Date),  an
amount equal to the Percentage  Interest  represented by this Certificate of the
amount  required to be  distributed to the  Certificateholders  of this Class on
such  Distribution  Date  pursuant to Section 4.01 of the Pooling and  Servicing
Agreement.

     All distributions  (other than the final distribution) shall be made to the
Persons in whose name the  Certificates  are registered at the close of business
on each  Record  Date by wire  transfer of  immediately  available  funds to the
account of such  Certificateholder  at a bank or other entity having appropriate
facilities  therefor  if  such  Certificateholder  shall  have so  notified  the
Certificate  Administrator  in writing by no later than five Business Days prior
to the  Record  Date  immediately  prior  to such  Distribution  Date and is the
registered  Certificateholder  of Certificates of the Class  represented by this
Certificate  with an  initial  Certificate  Balance  equal  to or in  excess  of
$5,000,000;   and  in  all   other   cases  by  check   mailed   to  each   such
Certificateholder   at  such   Certificateholder's   address  appearing  in  the
Certificate  Register,  in either case without  presentation or surrender of any
Certificate  held  by  such  Certificateholder  or the  making  of any  notation
thereon.  Distributions  on the final  Distribution  Date with  respect  to this
Certificate,   however,   shall  require   presentment  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  Pooling and  Servicing  Agreement  permits,  with  certain  exceptions
therein provided,  the amendment thereof, and the modification of the rights and
obligations of the Depositor,  the Servicer,  the Special Servicer,  the Trustee
and  the   Certificate   Administrator   thereunder   and  the   rights  of  the
Certificateholders  thereunder,  at any time by the Depositor, the Servicer, the
Special Servicer, the Trustee and the Certificate Administrator with the consent
of the Holders of  Certificates  entitled to at least 66 2/3% of the  Percentage
Interests of each Class affected thereby. 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 Pooling and Servicing Agreement also
permits the amendment thereof, in certain circumstances, including any amendment
necessary to maintain the status of  designated  portions of the Trust Fund as a
REMIC, without the consent of the Holders of any of the Certificates.

     No  sale,  transfer  or  other  disposition  of this  Certificate  shall be
permitted  other than in accordance  with the  provisions of Section 5.02 of the
Pooling and Servicing Agreement.

     This Certificate does not represent an obligation of, or an interest in the
Servicer,  the Special Servicer,  the Depositor,  the Trustee or the Certificate
Administrator,  except to the extent  described  in the  Pooling  and  Servicing
Agreement,  or any Affiliate  thereof,  nor will this  Certificate be insured or
guaranteed by any governmental  agency.  This Certificate is limited in right of
payment to certain  collections on the Mortgage Loans, as more  specifically set
forth in the Pooling and Servicing Agreement.

     The Holder hereof,  by its acceptance of this  Certificate,  agrees to look
solely to the assets of the Trust Fund, as provided in the Pooling and Servicing
Agreement,  for  payment  hereunder  and that the  Trustee  and the  Certificate
Administrator in their individual capacities are not liable to the Holder hereof
for any amounts  payable  under this  Certificate  or the Pooling and  Servicing
Agreement.

Agreement  and  is  qualified  in its  entirety  by the  Pooling  and  Servicing
Agreement.  Reference  is  made  to the  Pooling  and  Servicing  Agreement  for

     This    certifies    that    [____________________________________]    (the
"Certificateholder")  is the registered owner of a beneficial ownership interest
in a trust (the "Trust") created pursuant to a Pooling and Servicing  Agreement,
dated as of October 11, 1999 (the  "Pooling  and  Servicing  Agreement")  by and
among Wells Fargo Bank,  National  Association,  as servicer  (the  "Servicer"),
Lennar  Partners,  Inc., as special  servicer  ("Special  Servicer"),  The Chase
Manhattan Bank, as trustee (the "Trustee"),  Credit Suisse First Boston Mortgage
Securities  Corp.,  as depositor  (the  "Depositor")  and Norwest Bank Minnesota
National   Association,   as  certificate   administrator   and  custodian  (the
"Certificate  Administrator").   All  capitalized  terms  used  herein  and  not
otherwise defined herein shall have the meanings ascribed thereto in the Pooling
and  Servicing  Agreement.  This  Certificate  is  described  in the Pooling and
Servicing  Agreement  and is issued  pursuant  to and subject to the Pooling and
Servicing Agreement.  By acceptance of this Certificate,  each Certificateholder
assents to and becomes bound by the Pooling and Servicing Agreement.

     On each Distribution Date, the Certificate  Administrator  shall distribute
to the Person in whose name this  Certificate is registered on the last Business
Day of the month immediately preceding the month in which such Distribution Date
occurs (or with respect to the first  Distribution  Date, the Closing Date),  an
amount equal to the Percentage  Interest set forth above of the amount  required
to be distributed to the  Certificateholders  of this Class on such Distribution
Date pursuant to Section 4.01 of the Pooling and Servicing Agreement.

     All distributions  (other than the final distribution) shall be made to the
Persons in whose name the  Certificates  are registered at the close of business
on each  Record  Date by wire  transfer of  immediately  available  funds to the
account of such  Certificateholder  at a bank or other entity having appropriate

Certificate  Administrator  in writing by no later than five Business Days prior
to the  Record  Date  immediately  prior  to such  Distribution  Date and is the
registered  Certificateholder  of Certificates of the Class  represented by this
Certificate  with an initial  Percentage  Interest  equal to 13.73%,  and in all
other   cases  by  check   mailed  to  each  such   Certificateholder   at  such
Certificateholder's  address  appearing in the Certificate  Register,  in either
case  without  presentation  or  surrender  of  any  Certificate  held  by  such
Certificateholder  or the making of any notation  thereon.  Distributions on the
final Distribution Date with respect to this Certificate, however, shall require
presentment 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  Pooling and  Servicing  Agreement  permits,  with  certain  exceptions
therein provided,  the amendment thereof, and the modification of the rights and
obligations of the Depositor,  the Servicer,  the Special Servicer,  the Trustee
and  the   Certificate   Administrator   thereunder   and  the   rights  of  the
Certificateholders  thereunder,  at any time by the Depositor, the Servicer, the
Special Servicer, the Trustee and the Certificate Administrator with the consent
of the Holders of  Certificates  entitled to at least 66 2/3% of the  Percentage
Interests of each Class affected thereby. 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 Pooling and Servicing Agreement also
permits the amendment thereof, in certain circumstances, including any amendment
necessary to maintain the status of  designated  portions of the Trust Fund as a
REMIC, without the consent of the Holders of any of the Certificates.

     No  sale,  transfer  or  other  disposition  of this  Certificate  shall be
permitted  other than in accordance  with the  provisions of Section 5.02 of the
Pooling and Servicing Agreement.

     This Certificate does not represent an obligation of, or an interest in the
Servicer,  the Special Servicer,  the Depositor,  the Trustee or the Certificate
Administrator,  except to the extent  described  in the  Pooling  and  Servicing
Agreement,  or any Affiliate  thereof,  nor will this  Certificate be insured or
guaranteed by any governmental  agency.  This Certificate is limited in right of
payment to certain  collections on the Mortgage Loans, as more  specifically set
forth in the Pooling and Servicing Agreement.

     The Holder hereof,  by its acceptance of this  Certificate,  agrees to look
solely to the assets of the Trust Fund, as provided in the Pooling and Servicing
Agreement,   for  payment   hereunder  and  that  the  Trustee  and  Certificate
Administrator in their individual capacities are not liable to the Holder hereof
for any amounts  payable  under this  Certificate  or the Pooling and  Servicing
Agreement.

     This  Certificate  does not purport to summarize  the Pooling and Servicing
Agreement  and  is  qualified  in its  entirety  by the  Pooling  and  Servicing
Agreement.  Reference  is  made  to the  Pooling  and  Servicing  Agreement  for
information  with  respect  to the  interests,  rights,  benefits,  obligations,

     Re:      Transfer of Credit Suisse First Boston Mortgage Securities Corp.
              Commercial Mortgage Pass-Through Certificates, Series 1999-C1

Ladies and Gentlemen:

     This letter is delivered  pursuant to the  Confidential  Offering  Circular
(the  "Offering  Circular")  dated  November 4, 1999 and to Section  5.02 of the
Pooling and Servicing  Agreement  dated as of October 11, 1999 (the "Pooling and
Servicing  Agreement"),  by  and  among  Credit  Suisse  First  Boston  Mortgage
Securities  Corp.,  as Depositor,  Wells Fargo Bank,  National  Association,  as
Servicer,  Lennar Partners,  Inc., as Special Servicer,  Norwest Bank Minnesota,
National Association,  as Certificate Administrator and Custodian, and The Chase
Manhattan  Bank,  as Trustee,  on behalf of the holders of Credit  Suisse  First
Boston Mortgage Securities Corp. Commercial Mortgage Pass-Through  Certificates,
Series  1999-C1  (the   "Certificates")  in  connection  with  the  transfer  by
______________ to the undersigned (the  "Purchaser") of $____________  aggregate
Certificate Balance of Class ____ Certificates (the "Certificate").  Capitalized
terms used and not otherwise  defined herein shall have the respective  meanings
assigned to such terms in the Pooling and Servicing Agreement.

     In  connection  with  such  transfer,  unless  otherwise  directed  by  the
Depositor,  the  Purchaser  hereby  represents  and  warrants  to  you  and  the
addressees hereof as follows:

     1. The Purchaser is a "qualified institutional buyer" within the meaning of
Rule 144A ("Rule 144A") promulgated under the Securities Act of 1933, as amended
(the  "Securities  Act"). The Purchaser is aware that the transfer is being made
in reliance on Rule 144A,  and the Purchaser has had the  opportunity  to obtain
the information  required to be provided pursuant to paragraph (d)(4)(i) of Rule
144A.

     2.  The  Purchaser's  intention  is to  acquire  the  Certificate  (a)  for
investment  for the  Purchaser's  own  account,  (b) for  resale  to  "qualified
institutional  buyers" in  transactions  under Rule 144A,  or (c) in the case of
Class G or Class H  Certificates,  for  resale  to  persons  that are not  "U.S.
persons" within the meaning of Regulation S under the Securities Act, and not in
any event with the view to, or for resale in connection  with, any  distribution
thereof.  The Purchaser  understands  that the  Certificate  (and any subsequent
Certificate)  has not been  registered  under the Securities Act, by reason of a
specified exemption from the registration provisions of the Securities Act which
depends  upon,  among  other  things,  the bona fide  nature of the  Purchaser's
investment  intent (or  intent to resell to only  certain  investors  in certain
exempted transactions), as expressed herein.

     3. The Purchaser has reviewed the Offering  Circular and the agreements and
other materials referred to therein and has had the opportunity to ask questions
and receive  answers  concerning  the terms and  conditions of the  transactions
contemplated by the Offering Circular.

     4. The Purchaser  acknowledges  that the  Certificate  (and any Certificate
issued on transfer or exchange  thereof)  has not been  registered  or qualified
under  the  Securities  Act or the  securities  laws of any  State or any  other
jurisdiction,  and that the Certificate cannot be resold unless it is registered
or  qualified  thereunder,  or unless an  exemption  from such  registration  or
qualification is available.

     5. The Purchaser hereby  undertakes to be bound by the terms and conditions
of the  Pooling  and  Servicing  Agreement  in its  capacity  as an  owner  of a
Certificate or Certificates,  as the case may be (each, a  "Certificateholder"),
in all respects as if it were a signatory thereto.  This undertaking is made for
the   benefit   of  the   Trust,   the   Certificate   Administrator   and   all
Certificateholders present and future.

     6. The  Purchaser  will not sell or  otherwise  transfer any portion of the
Certificate  or  Certificates,  except in  compliance  with  Section 5.02 of the
Pooling and Servicing Agreement.

     7. The  Purchaser is a U.S.  Person (as defined  below) and it has attached
hereto an Internal Revenue Service ("IRS") Form W-9 (or successor form).

     For this  purpose,  "U.S.  Person"  means (i) a citizen or  resident of the
United  States,  (ii) a corporation  or  partnership  created or organized in or
under the laws of the  United  States,  any state  thereof  or the  District  of
Columbia,  (iii) an estate the income of which is includible in gross income for
United States tax purposes, regardless of its source, or (iv) a trust if a court
within  the  United  States  is  able to  exercise  primary  supervision  of the
administration of the trust and one or more such U.S. Persons have the authority
to control all substantial decisions of the trust.

     8.  The  Purchaser  is not (a) an  employee  benefit  plan  subject  to the
fiduciary  responsibility  provisions of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"),  or Section 4975 of the Internal Revenue Code
of 1986, as amended (the "Code"),  or a governmental plan (as defined in Section
3(32) of ERISA) subject to any federal, state or local law ("Similar Law") which
is, to a material  extent,  similar to the foregoing  provisions of ERISA or the
Code (each,  a "Plan"),  or (b) a person acting on behalf of or using the assets
of any such Plan  (including  an entity  whose  underlying  assets  include Plan
assets by reason of investment in the entity by such Plan and the application of
Department  of Labor  Regulation  Section  2510.3-101),  other than an insurance
company using the assets of its general account under circumstances  whereby the
purchase and holding of the  Certificates  by such  insurance  company  would be
eligible for the exemptive relief from the prohibited  transaction provisions of
ERISA and Section 4975 of the Code that is available under Sections I and III of
Prohibited Transaction Class Exemption 95-60.

     9. The Purchaser  understands that if it is a Person referred to in 8(a) or
(b)  above,   such   Purchaser  is  required  to  provide  to  the   Certificate
Administrator  an opinion of counsel in form and substance  satisfactory  to the
Certificate  Administrator  and the Depositor to the effect that the acquisition
and  holding  of such  Certificate  by such  purchaser  or  transferee  will not
constitute or result in a non-exempt prohibited transaction under ERISA, Section
4975 of the Code or any  Similar  Law and  will not  subject  the  Trustee,  the
Certificate  Administrator,  the  Servicer,  the Special  Servicer,  the Initial
Purchaser or the Depositor to any obligation or liability (including obligations
or  liabilities  under  ERISA,  Section  4975 of the Code or any Similar Law) in
addition  to those set  forth in the  Pooling  and  Servicing  Agreement,  which
opinion of counsel shall not be at the expense of the  Depositor,  the Servicer,
the Special Servicer, the Trustee or the Trust Fund.

     10. In the event that we purchase any of the Certificates,  we will acquire
Certificates  having a minimum  purchase  price of not less than $25,000 [in the
case of the  Class O  Certificates,  $100,000]  for our own  account  or for any
separate account for which we are acting.

     IN  WITNESS   WHEREOF,   the  Purchaser   hereby  executes  this  Qualified
Institutional Buyer Representation Letter on the ____ day of __________, ____.

                                    Very truly yours,

                                    [THE PURCHASER]

Ladies and Gentlemen:

     This letter is delivered  pursuant to the  Confidential  Offering  Circular
(the  "Offering  Circular")  dated  November 12, 1999 and to Section 5.02 of the
Pooling and Servicing  Agreement  dated as of October 11, 1999 (the "Pooling and
Servicing  Agreement"),  by  and  among  Credit  Suisse  First  Boston  Mortgage
Securities  Corp.,  as Depositor,  Wells Fargo Bank,  National  Association,  as
Servicer,  Lennar Partners,  Inc., as Special Servicer,  Norwest Bank Minnesota,

Boston Mortgage Securities Corp. Commercial Mortgage Pass-Through  Certificates,
Series  1999-C1  (the   "Certificates")  in  connection  with  the  transfer  by
[___________________________________]  to the undersigned  (the  "Purchaser") of
$____________  aggregate  Certificate Balance of Class [G] [H] Certificates (the
"Certificate").  Capitalized  terms used and not otherwise  defined herein shall
have the respective meanings assigned to such terms in the Pooling and Servicing
Agreement.

     In  connection  with  such  transfer,  unless  otherwise  directed  by  the
Depositor,  the  Purchaser  hereby  represents  and  warrants  to  you  and  the
addressees hereof as follows:

     1. The Purchaser is not a "U.S.  person" within the meaning of Regulation S
(a  "Non-U.S.  Person")  under  the  Securities  Act of 1933,  as  amended  (the
"Securities Act").

     2.  The  Purchaser's  intention  is to  acquire  the  Certificate  (a)  for
investment for the Purchaser's own account,  (b) for resale to Non-U.S.  Persons
in transactions under Regulation S or (c) for resale to "qualified institutional
buyers" in transactions under Rule 144A under the Securities Act, and not in any
event  with a view to,  or for  resale  in  connection  with,  any  distribution
thereof.  The Purchaser  understands  that the  Certificate  (and any subsequent
Certificate)  has not been  registered  under the Securities Act, by reason of a
specified exemption from the registration provisions of the Securities Act which
depends  upon,  among  other  things,  the bona fide  nature of the  Purchaser's
investment  intent (or  intent to resell to only  certain  investors  in certain
exempted transactions), as expressed herein.

     3. The Purchaser has reviewed the Offering  Circular and the agreements and
other materials referred to therein and has had the opportunity to ask questions
and receive  answers  concerning  the terms and  conditions of the  transactions
contemplated by the Offering Circular.

     4. The Purchaser  acknowledges  that the  Certificate  (and any Certificate
issued on transfer or exchange  thereof)  has not been  registered  or qualified
under  the  Securities  Act or the  securities  laws of any  State or any  other
jurisdiction,  and that the Certificate cannot be resold unless it is registered
or  qualified  thereunder,  or unless an  exemption  from such  registration  or
qualification is available.

     5. The Purchaser hereby  undertakes to be bound by the terms and conditions
of the  Pooling  and  Servicing  Agreement  in its  capacity  as an  owner  of a
Certificate or Certificates,  as the case may be (each, a  "Certificateholder"),
in all respects as if it were a signatory thereto.  This undertaking is made for
the   benefit   of  the   Trust,   the   Certificate   Administrator   and   all
Certificateholders present and future.

     6. The  Purchaser  will not sell or  otherwise  transfer any portion of the
Certificate  or  Certificates,  except in  compliance  with  Section 5.02 of the
Pooling and Servicing Agreement.

     7. The Purchaser is not a U.S. Person and under applicable law in effect 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  Certificate.  The
Purchaser  has  attached  hereto  either  (i) a duly  executed  IRS Form W-8 (or
successor form),  which identifies such Purchaser as the beneficial owner of the
Certificate and states that such Purchaser is not a U.S. Person or (ii) two duly
executed  copies of IRS Form  4224 (or  successor  form),  which  identify  such
Purchaser as the beneficial owner of the Certificate and state that interest and
original issue discount on the Certificate  and Permitted  Investments is, or is
expected  to be,  effectively  connected  with a U.S.  trade  or  business.  The
Purchaser agrees to provide to the Certificate  Administrator  updated IRS Forms
W-8 or IRS Forms 4224, as the case may be, any  applicable  successor IRS forms,
or such other  certifications  as the Certificate  Administrator  may reasonably
request,  on or before the date that any such IRS form or certification  expires
or becomes  obsolete,  or promptly after the occurrence of any event requiring a
change  in the most  recent  IRS form of  certification  furnished  by it to the
Certificate Administrator.

     For this  purpose,  "U.S.  Person"  means (i) a citizen or  resident of the
United States, (ii) a corporation or partnership  organized in or under the laws
of the United  States,  any state thereof or the District of Columbia,  (iii) an
estate the income of which is  includible  in gross income for United States tax
purposes,  regardless of its source or (iv) a trust if a court within the United
States is able to exercise  primary  supervision  of the  administration  of the
trust and one or more United  States  persons have the  authority to control all
substantial decisions of the trust.

     8.  The  Purchaser  is not (a) an  employee  benefit  plan  subject  to the
fiduciary  responsibility  provisions of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"),  or Section 4975 of the Internal Revenue Code
of 1986, as amended (the "Code"),  or a governmental plan (as defined in Section
3(32) of ERISA) subject to any federal, state or local law ("Similar Law") which
is, to a material  extent,  similar to the foregoing  provisions of ERISA or the
Code (each, a "Plan") or (b) a person acting on behalf of or using the assets of
any such Plan (including an entity whose  underlying  assets include Plan assets
by reason of  investment  in the  entity  by such  Plan and the  application  of
Department  of Labor  Regulation  Section  2510.3-101),  other than an insurance
company using the assets of its general account under circumstances  whereby the
purchase and holding of the  Certificates  by such  insurance  company  would be
eligible for the exemptive relief from the prohibited  transaction provisions of
ERISA and Section 4975 of the Code that is available under Sections I and III of
Prohibited Transaction Class Exemption 95-60.

     9. The Purchaser  understands that if it is a Person referred to in 8(a) or
(b)  above,   such   Purchaser  is  required  to  provide  to  the   Certificate
Administrator  an opinion of counsel in form and substance  satisfactory  to the
Certificate  Administrator  and the Depositor to the effect that the acquisition
and  holding  of such  Certificate  by such  purchaser  or  transferee  will not
constitute or result in a non-exempt prohibited transaction under ERISA, Section
4975 of the Code or any  Similar  Law and  will not  subject  the  Trustee,  the
Certificate  Administrator,  the  Servicer,  the Special  Servicer,  the Initial
Purchaser or the Depositor to any obligation or liability (including obligations
or  liabilities  under  ERISA,  Section  4975 of the Code or any Similar Law) in
addition  to those set  forth in the  Pooling  and  Servicing  Agreement,  which
opinion of counsel shall not be at the expense of the  Depositor,  the Servicer,
the Special Servicer, the Trustee or the Trust Fund.

     10. In the event that we purchase any of the Certificates,  we will acquire
Certificates  having a minimum  purchase  price of not less than $25,000 for our
own account or for any separate account for which we are acting.

       Re:      Transfer of Credit Suisse First Boston Mortgage Securities Corp.

Ladies and Gentlemen:

     This  letter is  delivered  pursuant  to Section  5.02 of the  Pooling  and
Servicing  Agreement  dated as of October 11, 1999 (the  "Pooling and  Servicing
Agreement"),  by and among Credit Suisse First Boston Mortgage Securities Corp.,
as  Depositor,  Wells Fargo Bank,  National  Association,  as  Servicer,  Lennar
Partners,   Inc.,  as  Special  Servicer,   Norwest  Bank  Minnesota,   National
Association, as Certificate Administrator and Custodian, and The Chase Manhattan
Bank,  as  Trustee,  on behalf of the  holders  of Credit  Suisse  First  Boston
Mortgage Securities Corp. Commercial Mortgage Pass-Through Certificates,  Series
1999-C1   (the    "Certificates")   in   connection   with   the   transfer   by
[______________________________________] to the undersigned (the "Purchaser") of
$____________  aggregate  Certificate  Balance  of  Class  O  Certificates  (the
"Certificate").  Capitalized  terms used and not otherwise  defined herein shall
have the respective meanings assigned to such terms in the Pooling and Servicing
Agreement.

     In  connection  with  such  transfer,  unless  otherwise  directed  by  the
Depositor,  the  Purchaser  hereby  represents  and  warrants  to  you  and  the
addressees hereof as follows:

     1.  We are an  institutional  "accredited  investor"  (as  defined  in Rule
501(a)(1), (2) or (3) under the Securities Act of 1933, as amended (the "Act")),
or an entity in which all of the equity owners are accredited  investors  within
the  meaning  of Rule  501(a)(1),  (2) or (3)  under  the  Act  (an  "Accredited
Investor") and we are acquiring the Certificates for investment purposes and not
with a view to, or for offer or sale in connection  with,  any  distribution  in
violation of the Act, and have such  knowledge  and  experience in financial and
business  matters  as to be capable  of  evaluating  the merits and risks of our
investment in the Certificates,  and we and any accounts for which we are acting
are each able to bear the economic risk of our or their investment.

     2. (A) any purchase of the Certificate by the Purchaser will be for its own
account  or for the  account  of one or more other  accredited  investors  or as
fiduciary for the account of one or more trusts, each of which is an "accredited
investor"  within the  meaning of Rule  501(a)(7)  under the Act and for each of
which the Purchaser exercises sole investment discretion or (B) the Purchaser is
a "bank,"  within the meaning of Section  3(a)(2) of the Act, or a "savings  and
loan  association" or other institution  described in Section  3(a)(5)(A) of the
Act that is acquiring  the  Certificate  as fiduciary  for the account of one or
more institutions for which the Purchaser exercises sole investment discretion.

     3. The  Purchaser  has  received and  reviewed  the  Confidential  Offering
Circular  relating  to  the  Certificate  (the  "Offering   Circular")  and  the
agreements and other  materials  referred to therein and has had the opportunity
to ask questions and receive answers  concerning the terms and conditions of the
transactions contemplated by the Offering Circular.

     4. The Purchaser  acknowledges  that the  Certificate  (and any Certificate
issued on transfer or exchange  thereof)  has not been  registered  or qualified
under  the  Securities  Act or the  securities  laws of any  State or any  other
jurisdiction,  and that the Certificate cannot be resold unless it is registered
or  qualified  thereunder  or unless an  exemption  from  such  registration  or
qualification is available.

     5. The Purchaser hereby  undertakes to be bound by the terms and conditions
of the  Pooling  and  Servicing  Agreement  in its  capacity  as an  owner  of a
Certificate or Certificates, as the case may be (each a "Certificateholder"), in
all respects as if it were a signatory thereto. This undertaking is made for the
benefit of the Trust, the Certificate  Administrator and all  Certificateholders
present and future.

     6. The  Purchaser  will not sell or  otherwise  transfer any portion of the
Certificate  or  Certificates,  except in  compliance  with  Section 5.02 of the
Pooling and Servicing Agreement.

     7. The  Purchaser is a U.S.  Person (as defined  below) and it has attached
hereto an Internal Revenue Service ("IRS") Form W-9 (or successor form).

     For this  purpose,  "U.S.  Person"  means (i) a citizen or  resident of the
United  States,  (ii) a corporation  or  partnership  created or organized in or
under the laws of the  United  States,  any state  thereof  or the  District  of
Columbia,  (iii) an estate the income of which is includible in gross income for
United States tax purposes,  regardless of its source or (iv) a trust if a court
within  the  United  States  is  able to  exercise  primary  supervision  of the
administration  of the trust and one or more U.S.  Persons have the authority to
control all substantial decisions of the trust.

     8.  The  Purchaser  is not (a) an  employee  benefit  plan  subject  to the
fiduciary  responsibility  provisions of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"),  or Section 4975 of the Internal Revenue Code
of 1986, as amended (the "Code"),  or a governmental plan (as defined in Section
3(32) of ERISA) subject to any federal, state or local law ("Similar Law") which
is, to a material  extent,  similar to the foregoing  provisions of ERISA or the
Code (each,  a "Plan"),  or (b) a person acting on behalf of or using the assets
of any such Plan  (including  an entity  whose  underlying  assets  include Plan
assets by reason of investment in the entity by such Plan and the application of
Department  of Labor  Regulation  Section  2510.3-101),  other than an insurance
company using the assets of its general account under circumstances  whereby the
purchase and holding of the  Certificates  by such  insurance  company  would be
eligible for the exemptive relief from the prohibited  transaction provisions of
ERISA and Section 4975 of the Code that is available under Sections I and III of
Prohibited Transaction Class Exemption 95-60.

     9. The Purchaser  understands that if it is a Person referred to in 8(a) or
(b)  above,   such   Purchaser  is  required  to  provide  to  the   Certificate
Administrator  an opinion of counsel in form and substance  satisfactory  to the
Certificate  Administrator  and the Depositor to the effect that the acquisition
and  holding  of such  Certificate  by such  purchaser  or  transferee  will not
constitute or result in a non-exempt prohibited transaction under ERISA, Section
4975 of the Code or any  Similar  Law,  and will not subject  the  Trustee,  the
Certificate  Administrator,  the  Servicer,  the Special  Servicer,  the Initial
Purchaser or the Depositor to any obligation or liability (including obligations
or  liabilities  under  ERISA,  Section  4975 of the Code or any Similar Law) in
addition  to those set  forth in the  Pooling  and  Servicing  Agreement,  which
opinion of counsel shall not be at the expense of the  Depositor,  the Servicer,
the Special Servicer, the Trustee or the Trust Fund.

     10. In the event that we purchase any of the Certificates,  we will acquire
Certificates  having a minimum  purchase price of not less than $100,000 for our
own account or for any separate account for which we are acting.
