            (c) Amounts received by the Master Servicer on behalf of the Trust

successor REO Mortgage Loan, notwithstanding that the terms of the related loan
documents so permit. To the extent any Post-ARD Additional Interest is not paid
on a current basis, it shall be deemed to be deferred interest.

            (e) Insofar as amounts received in respect of any Mortgage Loan or
REO Property and allocable to shared fees and shared charges owing in respect of
such Mortgage Loan or the related REO Mortgage Loan, as the case may be, that

that such file or report requires preparation and/or submission of data
concerning net cash flow or debt service coverage.

            Notwithstanding anything herein to the contrary, it is hereby
acknowledged that the groups of Mortgage Loans identified on the Mortgage Loan
Schedule as being cross-collateralized with each other are, in the case of each
such particular group of Mortgage Loans, by their terms, cross-defaulted and
cross-collateralized with each other. For purposes of reference only in this
Agreement, and without in any way limiting the servicing rights and powers of
the applicable Master Servicer and/or the applicable Special Servicer, with
respect to any Cross-Collateralized Mortgage Loan (or successor REO Mortgage
Loan), the Mortgaged Property (or REO Property) that relates or corresponds
thereto shall be the property identified in the Mortgage Loan Schedule as
corresponding thereto. The provisions of this Agreement, including each of the
defined terms set forth in Section 1.01, shall be interpreted in a manner
consistent with this Section 1.04; provided that, if there exists with respect
to any Cross- Collateralized Group only one original of any document referred to
in the definition of "Mortgage File" covering all the Mortgage Loans in such
Cross-Collateralized Group, then the inclusion of the original of such document
in the Mortgage File for any of the Mortgage Loans constituting such
Cross-Collateralized Group shall be deemed an inclusion of such original in the
Mortgage File for each such Mortgage Loan.

            Section 1.05 Certain Matters with Respect to the 622 Third Avenue
Loan and the Washington Center Loan

            (a) For the avoidance of doubt, the parties acknowledge that the
rights and duties of each of the Master Servicer and the Special Servicer under
this Agreement, insofar as such rights, duties and obligations relate to the 622
Third Avenue Loan and the Washington Center Loan (including the 622 Third Avenue
B Loan and the Washington Center Junior Loans), shall terminate upon the
earliest to occur of the following with respect to the 622 Third Avenue Loan and
the Washington Center Loan: (i) any repurchase of or substitution for the A Note
by the Mortgage Loan Seller of the 622 Third Avenue Loan or the Washington
Center Loan, (ii) any purchase of the A Note by any Washington Center Junior

to the terms of the related A/B Intercreditor Agreement and (iii) any payment in
full of any and all amounts due (or deemed due) under the related A Note (or its
successor REO Mortgage Loan) (including amounts to which the holder of the
related A Note is entitled under the related A/B Intercreditor Agreement);
provided, however, that this statement shall not limit (A) the duty of the
Master Servicer or Special Servicer to deliver or make available the reports
otherwise required of it hereunder with respect to the period in which such
event occurs or (B) the rights of the Master Servicer or such Special Servicer
that may otherwise accrue or arise in connection with the performance of its
duties hereunder with respect to the 622 Third Avenue Loan and the Washington
Center Loan prior to the date on which such event occurs.

            (b) In connection with any purchase described in clause (ii) of
subsection (a) or an event described in clause (iii) of subsection (a), the
Trustee, the Master Servicer and the Special Servicer (to the extent it
possesses any such items) shall each tender to (in the case of a purchase under
such clause (ii)) the related purchaser (provided that the related purchaser
shall have paid the full amount of the applicable purchase price) or (in the
case of such clause (iii)) to the holders of the 622 Third Avenue B Loan and the
Washington Center Junior Loans (if then still outstanding), upon delivery to
them of a receipt executed by such purchaser or holder, all portions of the
Mortgage File possessed by the Trustee and other documents pertaining to the
Washington Center Loan, possessed by the Trustee, and each document that
constitutes a part of the Mortgage File shall be endorsed or assigned by the
Trustee to the extent necessary or appropriate to such purchaser or holder (or
the designee of such purchaser or holder) in the same manner, and pursuant to
appropriate forms of assignment prepared by the Master Servicer, substantially
similar to the manner and forms pursuant to which documents were previously
assigned to the Trustee by the Column Mortgage Loan Seller, but in any event,
without recourse, representation or warranty; provided that such tender by the
Trustee shall be conditioned upon its receipt from the Master Servicer of a
Request for Release in the form of Exhibit D-1 hereto which the applicable
Master Servicer shall promptly deliver upon the occurrence of any purchase
described in clauses (i) and (ii) of Subsection (a). The Master Servicer shall,
and is also hereby authorized and empowered by the Trustee to, upon receipt of
notice of such purchase, convey to such purchaser or such holder any deposits
then held in an Escrow Account relating to the 622 Third Avenue Loan and the
Washington Center Loan. If the A Note and the related B Loan or Washington
Center Junior Loans are then REO Mortgage Loans, then the Special Servicer
shall, and is also hereby authorized and empowered by the Trustee to, upon
receipt of notice to do so, convey to such purchaser or such holder, in each
case, to the extent not needed to pay or reimburse the Master Servicer, the
Special Servicer, the Trustee or any Fiscal Agent in accordance with this
Agreement, deposits then held in the REO Account insofar as they relate to the
related REO Property.

                                  CERTIFICATES

            Section 2.01 Conveyance of Mortgage Loans

            (a) It is the intention of the parties hereto that a common law
trust be established under the laws of the State of New York pursuant to this
Agreement and, further, that such trust be designated as "CSFB Commercial
Mortgage Trust 2003-C3." Wells Fargo is hereby appointed, and does hereby agree
to act, as Trustee hereunder and, in such capacity, to hold the Trust Fund in
trust for the exclusive use and benefit of all present and future
Certificateholders. It is not intended that this Agreement create a partnership
or a joint-stock association.

            (b) The Depositor, concurrently with the execution and delivery
hereof, does hereby sell, assign, transfer and otherwise convey to the Trustee
without recourse for the benefit of the Certificateholders, all the right, title
and interest of the Depositor in, to and under (i) the Original Mortgage Loans,
all payments under and proceeds of such Mortgage Loans received after the
Closing Date (other than scheduled payments of interest and principal due on or
before the respective Due Dates for the Original Mortgage Loans in June 2003),
and all documents included in the related Mortgage Files and Servicing Files and
any related Additional Collateral; (ii) any REO Property acquired in respect of
any such Mortgage Loan (or, in the case of any Great Lakes Crossing REO
Property, the Trust's interest therein); (iii) such funds or assets as from time
to time are deposited in the Collection Account, the Distribution Account, the
Interest Reserve Account, the Excess Liquidation Proceeds Account, the Great
Lakes Crossing Custodial Account (if established) and the Series 2003-CK2
Companion Loan Custodial Account and, if established, the REO Account; (iv) the
Mortgage Loan Purchase Agreements; (v) the Column Performance Guarantee; and
(vi) all other assets included or to be included in the Trust Fund. This
conveyance is subject to the right of the Designated Sub-Servicers to primary
service certain of the Original Mortgage Loans pursuant to the Designated
Sub-Servicer Agreements.

            Under GAAP, the Depositor shall report and cause all of its records
to reflect: (i) its acquisition of the Original Column Mortgage Loans from
Column, pursuant to the Column Mortgage Loan Purchase Agreement, as a purchase
of such Mortgage Loans from Column; (ii) its acquisition of the Original KeyBank
Mortgage Loans from KeyBank, pursuant to the KeyBank Mortgage Loan Purchase
Agreement, as a purchase of such Mortgage Loans from KeyBank; (iii) its
acquisition of the Original Eurohypo Mortgage Loan from Eurohypo, pursuant to
the Eurohypo Mortgage Loan Purchase Agreement, as a purchase of such Mortgage
Loan from Eurohypo; (iv) its acquisition of the Original NCBFSB Mortgage Loans
from NCBFSB, pursuant to the NCBFSB Mortgage Loan Purchase Agreement, as a
purchase of such Mortgage Loans from NCBFSB; (v) its acquisition of the Original
PNC Mortgage Loans from PNC, pursuant to the PNC Mortgage Loan Purchase
Agreement, as a purchase of such Mortgage Loans from PNC; and (vi) its transfer
of the Original Mortgage Loans to the Trust, pursuant to this Section 2.01(b),
as a sale of such Mortgage Loans to the Trust; provided that, in the case of the
transactions described in clauses (i) and (vi) of this sentence, the Depositor
shall do so only upon the sale of Certificates representing at least 10% of the
aggregate Certificate Principal Balance of all the Certificates to parties that
are not Affiliates of the Depositor. Regardless of its treatment of the transfer
of the Original Mortgage Loans to the Trust under GAAP, the Depositor shall at
all times following the Closing Date cause all of its records and financial
statements and any relevant consolidated financial statements of any direct or
indirect parent clearly to reflect that the Original Mortgage Loans have been
transferred to the Trust and are no longer available to satisfy claims of the
Depositor's creditors.

            After the Depositor's transfer of the Original Mortgage Loans to the
Trustee pursuant to this Section 2.01(b), the Depositor shall not take any
action inconsistent with the Trust's ownership of the Mortgage Loans.

            (c) The conveyance of the Original Mortgage Loans and the related
rights and property accomplished hereby is absolute and is intended by the
parties hereto to constitute an absolute transfer of such Mortgage Loans and
such other related rights and property by the Depositor to the Trustee for the
benefit of the Certificateholders. Furthermore, it is not intended that such
conveyance be a pledge of security for a loan. If such conveyance is determined
to be a pledge of security for a loan, however, the Depositor and the Trustee
intend that the rights and obligations of the parties to such loan shall be
established pursuant to the terms of this Agreement. The Depositor and the
Trustee also intend and agree that, in such event, (i) this Agreement shall
constitute a security agreement under applicable law, (ii) the Depositor shall
be deemed to have granted to the Trustee (in such capacity) a first priority
security interest in all of the Depositor's right, title and interest in and to
the assets constituting the Trust Fund, including the Mortgage Loans subject
hereto from time to time, all principal and interest received on or with respect
to such Mortgage Loans after the Closing Date (other than scheduled payments of
interest and principal due and payable on such Mortgage Loans on or prior to the
related Due Date in June 2003 or, in the case of a Replacement Mortgage Loan, on
or prior to the related date of substitution), all amounts held from time to
time in each Collection Account, the Distribution Account, the Interest Reserve
Account, the Excess Liquidation Proceeds Account, each REO Account (if
established), the Great Lakes Crossing Custodial Account (if established) and
the Series 2003-CK2 Companion Loan Custodial Account, and all investment
earnings on such amounts, and all of the Depositor's right, title and interest
under the Mortgage Loan Purchase Agreements and the Column Performance
Guarantee, (iii) the possession by the Trustee or its agent of the Mortgage
Notes with respect to the Mortgage Loans subject hereto from time to time and
such other items of property as constitute instruments, money, negotiable
documents or chattel paper shall be deemed to be "possession by the secured
party" or possession by a purchaser or person designated by such secured party
for the purpose of perfecting such security interest under applicable law, and
(iv) notifications to, and acknowledgments, receipts or confirmations from,
Persons holding such property, shall be deemed to be notifications to, or
acknowledgments, receipts or confirmations from, securities intermediaries,
bailees or agents (as applicable) of the Trustee for the purpose of perfecting
such security interest under applicable law. The Depositor shall file or cause
to be filed, as a precautionary filing, a Form UCC-1 financing statement
substantially in the form attached as Exhibit J hereto in all appropriate
locations in the State of Delaware promptly following the initial issuance of
the Certificates, and the General Master Servicer shall prepare and file at each
such office, and the Trustee shall authorize continuation statements with
respect thereto, in each case within six months prior to the fifth anniversary,
and each succeeding anniversary that is a five-year multiple of the anniversary,
of the date of the filing of the applicable UCC Financing Statement. The
Depositor hereby authorizes the Trustee and the General Master Servicer to
prepare and file in the name of the Depositor, and shall cooperate in a
reasonable manner with the Trustee and the Master Servicers in preparing and
filing, such continuation statements. This Section 2.01(c) shall constitute
notice to the Trustee pursuant to any requirements of the UCC in effect in each
applicable jurisdiction.

            (d) In connection with the Depositor's assignment pursuant to
Section 2.01(b) above, the Depositor hereby represents and warrants that it has
contractually obligated each Mortgage Loan Seller, at such Mortgage Loan
Seller's expense, pursuant to the related Mortgage Loan Purchase Agreement, to
deliver to and deposit with, or cause to be delivered to and deposited with, the
Trustee or a Custodian appointed thereby, on or before the Closing Date, the
Mortgage File and any Additional Collateral (other than Reserve Funds) for each
Original Mortgage Loan acquired by the Depositor from such Mortgage Loan Seller.
In addition, with respect to each Mortgage Loan under which any Additional
Collateral is in the form of a Letter of Credit as of the Closing Date, the
Depositor hereby represents and warrants that it has contractually obligated the
related Mortgage Loan Seller, subject to the next paragraph, to cause to be
prepared, executed and delivered to the issuer of each such Letter of Credit
such notices, assignments and acknowledgments as are required under such Letter
of Credit to assign, without recourse, to the Trustee (whether by actual
assignment or by amendment of the Letter of Credit) the related Mortgage Loan
Seller's rights as the beneficiary thereof and drawing party thereunder. The
Depositor shall deliver to the Trustee on or before the Closing Date a fully
executed counterpart of each Mortgage Loan Purchase Agreement and the Column
Performance Guarantee.

            Notwithstanding the foregoing, if any Mortgage Loan Seller is unable
to deliver any Letter of Credit constituting Additional Collateral for any of
its Original Mortgage Loans, then that Mortgage Loan Seller may, in lieu
thereof, deliver on behalf of the related Borrower, to be used for the same
purposes as such missing Letter of Credit either: (i) a substitute instrument
substantially comparable to, but in all cases in the same amount and with the
same draw conditions and renewal rights as, that Letter of Credit and issued by
an obligor that meets any criteria in the related Mortgage Loan Documents
applicable to the issuer of that Letter of Credit; or (ii) a LOC Cash Reserve in
an amount equal to the amount of that Letter of Credit. For purposes of the
delivery requirements of this Section 2.01, any such substitute instrument shall
be deemed to be Additional Collateral of the type covered by the prior paragraph
of this Section 2.01(d) and any such LOC Cash Reserve shall be deemed to be
Reserve Funds of the type covered by Section 2.01(f).

            (e) As soon as reasonably possible, and in any event within 90 days
after the later of (i) the Closing Date (or, in the case of a Replacement
Mortgage Loan substituted as contemplated by Section 2.03, after the related
date of substitution) and (ii) the date on which all recording information
necessary to complete the subject document is received by the Trustee, the
Trustee shall complete (to the extent necessary), and shall submit for recording
or filing, as the case may be, including via electronic means, if appropriate,
in or with the appropriate office for real property records or UCC Financing
Statements, as applicable, each assignment of Mortgage and assignment of
Assignment of Leases in favor of the Trustee referred to in clauses (a)(iv) and
(a)(v) of the definition of "Mortgage File" that has been received by the
Trustee or a Custodian on its behalf and each UCC-2 or UCC-3 assignment in favor
of the Trustee referred to in clause (a)(viii) of the definition of "Mortgage
File" that has been received by the Trustee or a Custodian on its behalf. Each
such assignment shall reflect that it should be returned by the public recording
office to the Trustee following recording, and each such UCC-2 or UCC-3
assignment shall reflect that the filed copy thereof or an appropriate receipt
therefor, as applicable, should be returned to the Trustee following filing;
provided that in those instances where the public recording office retains the
original assignment of Mortgage or assignment of Assignment of Leases the
Trustee shall obtain therefrom a copy of the recorded original. At such time as
such assignments, UCC-2s, UCC-3s or verifications of electronic filing have been
returned to the Trustee, the Trustee shall forward a copy thereof to the
applicable Master Servicer. If any such document or instrument is lost or
returned unrecorded or unfiled, as the case may be, because of a defect therein,
the Trustee shall direct the related Mortgage Loan Seller to prepare or cause to
be prepared promptly, pursuant to the related Mortgage Loan Purchase Agreement,
a substitute therefor or cure such defect, as the case may be, and thereafter
the Trustee shall, upon receipt thereof, cause the same to be duly recorded or
filed, as appropriate. If any Mortgage Loan Seller has been so notified and has
not prepared a substitute document or cured such defect, as the case may be,
within 60 days, the Trustee shall promptly notify the applicable Master
Servicer, the applicable Special Servicer, the Rating Agencies and the
Controlling Class Representative. Each Mortgage Loan Seller shall be responsible
for paying the reasonable fees and out-of-pocket expenses of the Trustee in
connection with the above-referenced recording and filing of documents insofar
as it relates to the Original Mortgage Loans acquired by the Depositor from such
Mortgage Loan Seller, all as more particularly provided for in the related
Mortgage Loan Purchase Agreement.

            Notwithstanding the foregoing, any Mortgage Loan Seller may elect
(in writing to the Trustee), at its sole cost and expense, to engage a
third-party contractor to prepare and complete in proper form for filing and
recording any and all of the assignments described in the immediately preceding
paragraph, including UCC-2 and UCC-3 assignments with respect to the Original
Mortgage Loans conveyed by it to the Depositor under the applicable Mortgage
Loan Purchase Agreement, to submit such assignments for filing and recording, as
the case may be, in the applicable public filing and recording offices and to
deliver such assignments to the Trustee or its designee as such assignments (or
certified copies thereof) are received from the applicable filing and recording
offices with evidence of such filing and recording indicated thereon. It is
hereby acknowledged that the PNC Mortgage Loan Seller has elected to engage such
a third-party contractor for the preparation, filing and recording and delivery
of such assignments to the Trustee in respect of the Original PNC Mortgage
Loans. The Trustee shall have no duties or obligations described in the
immediately preceding paragraph in respect of the Original PNC Mortgage Loans or
the Original Mortgage Loans provided by any other Mortgage Loan Seller that
makes a similar election with respect to its Original Mortgage Loans.

            (f) In connection with the Depositor's assignment pursuant to
Section 2.01(b) above, the Depositor hereby represents and warrants that it has
contractually obligated each Mortgage Loan Seller, at such Mortgage Loan
Seller's expense, pursuant to the related Mortgage Loan Purchase Agreement, to
deliver to and deposit with, or cause to be delivered to and deposited with, the
applicable Master Servicer, within three (3) Business Days after the Closing
Date, the following items (except to the extent that any of the following items
are to be retained by a primary servicer that will continue to act on behalf of
the applicable Master Servicer as a Sub-Servicer): (i) originals or copies of
all financial statements, appraisals, environmental/engineering reports,
transaction screens, leases, rent rolls (except with respect to Co-op Mortgage
Loans), third-party underwriting reports, insurance policies, legal opinions,
tenant estoppels and any other relevant documents that the applicable Master
Servicer or applicable Special Servicer reasonably deems necessary to service
the subject Mortgage Loan in the possession or under the control of such
Mortgage Loan Seller that relate to the Original Mortgage Loans transferred by
it to the Depositor, copies of all documents required to be delivered by such
Mortgage Loan Seller to the Trustee or Custodian as a part of the related
Mortgage File and, to the extent they are not required to be a part of a
Mortgage File for any such Original Mortgage Loan, originals or copies of all
documents, certificates and opinions in the possession or under the control of
such Mortgage Loan Seller that were delivered by or on behalf of the related
Borrowers in connection with the origination of such Original Mortgage Loans
(provided, that (other than the underwriting model contained in the related
underwriting memorandum or asset summary report prepared by any Mortgage Loan
Seller and provided to Ernst & Young, LLP in connection with the preparation of
Exhibit A-1 to the Prospectus Supplement) such Mortgage Loan Seller shall not be
required to deliver any attorney-client privileged communication or any
documents or materials prepared by it or its Affiliates solely for internal
credit analysis or other internal uses); and (ii) all unapplied Reserve Funds
and Escrow Payments in the possession or under the control of such Mortgage Loan
Seller that relate to the Original Mortgage Loans transferred by such Mortgage
Loan Seller to the Depositor. The Master Servicers shall hold all such
documents, records and funds that it so receives on behalf of the Trustee in
trust for the benefit of the Certificateholders and, insofar as such items
relate to a B Loan or the Washington Center Junior Loans, the related B Loan
Holder or Washington Center Junior Holders, as applicable.

            (g) Also in connection with the Depositor's assignment pursuant to
Section 2.01(b) above, the Depositor shall deliver to and deposit with, or cause
to be delivered to and deposited with, the applicable Master Servicer, on or
before the Closing Date, the original or a copy of any Group Environmental
Insurance Policy acquired by the Depositor or an Affiliate of the Depositor.

            Section 2.02 Acceptance of Mortgage Assets by Trustee

            (a) Subject to the other provisions in this Section 2.02, the
Trustee, by its execution and delivery of this Agreement, hereby accepts receipt
on behalf of the Trust, directly or through a Custodian on its behalf, of (i)
the Original Mortgage Loans and all documents delivered to it that constitute
portions of the related Mortgage Files and (ii) all other assets delivered to it
and included in the Trust Fund, in good faith and without notice of any adverse
claim, and declares that it or a Custodian on its behalf holds and will hold
such documents and any other documents received by it that constitute portions
of the Mortgage Files, and that it holds and will hold the Original Mortgage
Loans and such other assets, together with any other Mortgage Loans and assets
subsequently delivered to it that are to be included in the Trust Fund, in trust
for the exclusive use and benefit of all present and future Certificateholders.
The Trustee or such Custodian (acting through the applicable Master Servicer)
shall hold any Letter of Credit in a custodial capacity only and shall have no
obligation to maintain, extend the term of, enforce or otherwise pursue any
rights under such Letter of Credit which obligation the applicable Master
Servicer hereby undertakes. In connection with the foregoing, the Trustee hereby
certifies to each of the other parties hereto and the Mortgage Loan Sellers
that, as to each Original Mortgage Loan, except as to any LOC Cash Reserve and
except as specifically identified in the Schedule of Exceptions to Mortgage File
Delivery attached hereto as Exhibit B-2, (i) the Specially Designated Mortgage
Loan Documents (without regard to Assignments of Leases, modification agreements
and assumption agreements) are in its possession or the possession of a
Custodian on its behalf, and (ii) such Mortgage Loan Documents have been
reviewed by it or by such Custodian on its behalf and (A) appear regular on
their face (handwritten additions, changes or corrections shall not constitute
irregularities if initialed by the Borrower), (B) appear to have been executed
and (C) purport to relate to such Mortgage Loan. To the extent that the contents
of the Mortgage File for any A Loan relate to the corresponding B Loan or
Washington Center Junior Loans, as the case may be, the Trustee will also hold
such Mortgage File in trust for the benefit of the holder of the related B Loan
or the Washington Center Junior Loans.

            (b) On or about the 75th day following the Closing Date (and, if any
exceptions are noted or if the recordation/filing contemplated by Section
2.01(e) has not been completed (based solely on receipt by the Trustee of the
particular documents showing evidence of the recordation/filing), every 90 days
thereafter until the earlier of (i) the date on which such exceptions are
eliminated and such recordation/filing has been completed, and (ii) the date on
which all the affected Mortgage Loans are removed from the Trust Fund), the
Trustee or a Custodian on its behalf shall review the documents delivered to it
or such Custodian with respect to each Original Mortgage Loan, and the Trustee
shall, subject to Sections 1.04, 2.02(c) and 2.02(d), certify in writing
(substantially in the form of Exhibit B-3) to each of the other parties hereto,
the Mortgage Loan Sellers and the Controlling Class Representative that, as to
each Original Mortgage Loan then subject to this Agreement (except as to any LOC
Cash Reserve and except as specifically identified in any exception report
annexed to such certification): (i) the original Mortgage Note specified in
clause (a)(i) of the definition of "Mortgage File" and all allonges thereto, if
any (or a copy of such Mortgage Note, together with a lost note affidavit and
indemnity certifying that the original of such Mortgage Note has been lost), the
original or copy of documents specified in clauses (a)(ii) through (a)(v),
(a)(vii), (a)(x), (a)(xii) and (a)(xiii) of the definition of "Mortgage File"
and, in the case of a hospitality property, the documents specified in clause
(a)(viii) of the definition of "Mortgage File" (without regard to the
parenthetical) and any other Specially Designated Mortgage Loan Documents
(without regard to modification agreements and assumption agreements), have been
received by it or a Custodian on its behalf; (ii) if such Mortgage Loan is the
Great Lakes Crossing Mortgage Loan, the original Mortgage Note specified in
clause (b)(i) of the definition of "Mortgage File" and all allonges thereto, if
any (or a copy of such Mortgage Note, together with a "lost note affidavit and
indemnity" certifying that the original of such Mortgage Note has been lost),
and the original or a copy of each document specified in clauses (b)(ii) and
(b)(iii) of the definition of "Mortgage File", have been received by the Trustee
or a Custodian on its behalf; (iii) if such report is due more than 180 days
after the Closing Date, the recordation/filing contemplated by Section 2.01(e)
(except in the case of the Great Lakes Crossing Mortgage Loan) has been
completed (based solely on receipt by the Trustee of the particular
recorded/filed documents or an appropriate receipt of recording/filing
therefor); (iv) all documents received by it or any Custodian with respect to
such Mortgage Loan have been reviewed by it or by such Custodian on its behalf
and (A) appear regular on their face (handwritten additions, changes or
corrections shall not constitute irregularities if initialed by the Borrower),
(B) appear to have been executed and (C) purport to relate to such Mortgage
Loan; and (v) based on the examinations referred to in Section 2.02(a) above and
this Section 2.02(b) and only as to the foregoing documents, the information set
forth in the Mortgage Loan Schedule with respect to the items specified in
clause (iii)(A) and clause (vi) of the definition of "Mortgage Loan Schedule"
accurately reflects the information set forth in the related Mortgage File.

            If a Mortgage Loan Seller or the Column Performance Guarantor
substitutes a Replacement Mortgage Loan for any Defective Mortgage Loan as
contemplated by Section 2.03, the Trustee or a Custodian on its behalf shall
review the documents delivered to it or such Custodian with respect to such
Replacement Mortgage Loan, and the Trustee shall deliver a certification
comparable to that described in the prior paragraph, in respect of such
Replacement Mortgage Loan, on or about the 30th day following the related date
of substitution (and, if any exceptions are noted, every 90 days thereafter
until the earlier of (i) the date on which such exceptions are eliminated and
all related recording/filing has been completed, and (ii) the date on which such
Replacement Mortgage Loan is removed from the Trust Fund).

            With respect to the documents described in clause (a)(iii) of the
definition of "Mortgage File", absent actual knowledge to the contrary, the
Trustee may assume, for purposes of the certification(s) delivered in this
Section 2.02(a) or to be delivered pursuant to Section 2.02(b), that the
Mortgage File for each Mortgage Loan includes a separate Assignment of Leases.

            With respect to the documents described in clause (a)(viii) of the
definition of "Mortgage File", absent actual knowledge to the contrary or copies
of UCC Financing Statements delivered to the Trustee as part of the Mortgage
File indicating otherwise, the Trustee may assume, for purposes of the
certification(s) to be delivered pursuant to this Section 2.02(b), that the
Mortgage File for each Mortgage Loan should include one state-level UCC
Financing Statement filing in the state of incorporation or organization of the
related Borrower for each Mortgaged Property (or with respect to any Mortgage
Loan that has two or more Borrowers, for each related Borrower). To the extent
appropriate under applicable law, the UCC-2s and UCC-3s in favor of the Trustee
will be delivered on the new national forms and in recordable form and will be
filed in the state of incorporation or organization as so indicated on the
documents provided.

            (c) None of the Trustee, the Master Servicers, the Special Servicers
or any Custodian is under any duty or obligation to inspect, review or examine
any of the documents, instruments, certificates or other papers relating to the
Mortgage Loans delivered to it to determine that the same are valid, legal,
effective, genuine, binding, enforceable, sufficient or appropriate for the
represented purpose or that they are other than what they purport to be on their
face or to determine whether any of the representations and warranties made by
any Mortgage Loan Seller in its respective Mortgage Loan Purchase Agreement are
true and correct when made. Furthermore, except as expressly provided in Section
2.01(e), none of the Trustee, the Master Servicers, the Special Servicers or any
Custodian shall have any responsibility for determining whether the text of any
assignment or endorsement is in proper or recordable form, whether the requisite
recording of any document is in accordance with the requirements of any
applicable jurisdiction, or whether a blanket assignment is permitted in any
applicable jurisdiction.

            (d) In performing the reviews contemplated by subsections (a) and
(b) above, the Trustee may conclusively rely on the related Mortgage Loan Seller
as to the purported genuineness of any such document and any signature thereon.
It is understood that the scope of the Trustee's review of the Mortgage Files is
limited solely to confirming that the documents specified in clauses (a)(i)
through (a)(v), clause (a)(vii) and, in the case of any Mortgage Loan secured by
a Mortgage on a hospitality property, clause (a)(viii) of the definition of
"Mortgage File" and any other Specially Designated Mortgage Loan Documents
(without regard to modification agreements and assumption agreements), have been
received and such additional information as will be necessary for delivering the
certifications required by subsections (a) and (b) above.

            Section 2.03 Certain Repurchases and Substitutions of Mortgage Loans
by the Mortgage Loan Sellers or the Column Performance Guarantor

            (a) If any party hereto discovers (without implying any duty to make
such discovery), or receives notice from a non-party, that a Document Defect or
Breach exists with respect to any Mortgage Loan, then such party shall give
prompt written notice thereof to the other parties hereto, including (unless it
is the party that discovered the Document Defect or Breach) the Trustee. Upon
the Trustee's discovery or receipt of notice that a Document Defect or Breach
exists with respect to any Mortgage Loan, the Trustee shall notify the
Controlling Class Representative, the Depositor and each Person that would be a
Responsible Party with respect thereto if such Document Defect or Breach, as the
case may be, were a Material Document Defect or a Material Breach, as
applicable.

            If necessary, the Trustee shall request each Mortgage Loan Seller to
comply with the second paragraph of Section 2(c) of the related Mortgage Loan
Purchase Agreement with respect to any Document Defect or other deficiency in a
Mortgage File relating to an Original Mortgage Loan transferred by such Mortgage
Loan Seller to the Depositor. If the Trustee becomes aware of any failure on the
part of any Mortgage Loan Seller to do so, the Trustee shall promptly notify the
applicable Master Servicer and the applicable Special Servicer.

            (b) Promptly upon its determination that any Material Document
Defect or Material Breach exists with respect to any Mortgage Loan or its
receipt of notice from the Trustee or any other party to this Agreement of a
Material Document Defect or Material Breach with respect to any Mortgage Loan,
the applicable Master Servicer or the applicable Special Servicer with respect
to Specially Serviced Mortgage Loans, shall notify the Responsible Party or
Parties with respect thereto in writing of such Material Document Defect or
Material Breach, as the case may be, and direct such Responsible Party or
Parties that it or they, as the case may be, must, not later than 90 days from
the receipt by such Responsible Party or Parties of such notice (or, if such
Material Breach or Material Document Defect, as the case may be, relates to
whether such Mortgage Loan is or, as of the Closing Date (or, in the case of a
Replacement Mortgage Loan, as of the related date of substitution), was a
Qualified Mortgage, and provided that such Responsible Party or Parties received
prompt written notice thereof, within 90 days after any earlier discovery by any
party to this Agreement of such Material Breach or Material Document Defect, as
the case may be) (such 90-day period, in any case, the "Initial Resolution
Period"), correct or cure such Material Document Defect or Material Breach, as
the case may be, in all material respects, or repurchase the affected Mortgage
Loan (as, if and to the extent required by the related Mortgage Loan Purchase
Agreement or the Column Performance Guarantee), at the applicable Purchase
Price; provided that if a Responsible Party with respect to any Material
Document Defect or Material Breach certifies to the Trustee in writing (i) that
such Material Document Defect or Material Breach, as the case may be, does not
relate to whether the affected Mortgage Loan is or, as of the Closing Date (or,
in the case of a Replacement Mortgage Loan, as of the related date of
substitution), was a Qualified Mortgage, (ii) that such Material Document Defect
or Material Breach, as the case may be, is capable of being cured but not within
the applicable Initial Resolution Period, (iii) that such Responsible Party has
commenced and is diligently proceeding with the cure of such Material Document
Defect or Material Breach, as the case may be, during the applicable Initial
Resolution Period, (iv) what actions such Responsible Party is pursuing in
connection with the cure of such Material Document Defect or Material Breach, as
the case may be, and (v) that such Responsible Party anticipates that such
Material Document Defect or Material Breach, as the case may be, will be cured
within an additional 90-day period (such additional 90-day period, the
"Resolution Extension Period") (a copy of which certification shall be delivered
by the Trustee to the applicable Master Servicer, the applicable Special
Servicer and the Controlling Class Representative), then such Responsible Party
(or, if applicable, both of the Responsible Parties with respect to such
Material Document Defect or Material Breach, as the case may be) shall have an
additional period equal to any such applicable Resolution Extension Period to
complete such correction or cure (or, upon failure to complete such correction
or cure, to repurchase the affected Mortgage Loan); and provided, further, that,
in lieu of repurchasing the affected Mortgage Loan as contemplated above (but,
in any event, no later than such repurchase would have to have been completed),
a Responsible Party with respect to any Material Document Defect or Material
Breach shall be permitted, during the three-month period following the Startup
Day for any Trust REMIC that holds the related Mortgage Loan (or during the
two-year period following such Startup Day if the affected Mortgage Loan is a
"defective obligation" within the meaning of Section 860G(a)(4)(B)(ii) of the
Code and Treasury Regulations Section 1.860G-2(f)), to replace the affected
Mortgage Loan with one or more Qualifying Substitute Mortgage Loans and to pay a
cash amount equal to the applicable Substitution Shortfall Amount, subject to
any other applicable terms and conditions of the related Mortgage Loan Purchase
Agreement or the Column Performance Guarantee, as applicable, and this
Agreement. If any Mortgage Loan is to be repurchased or replaced as contemplated
by this Section 2.03, the applicable Master Servicer shall designate its
Collection Account as the account to which funds in the amount of the applicable
Purchase Price or Substitution Shortfall Amount (as the case may be) are to be
wired, and the applicable Master Servicer shall promptly notify the Trustee when
such deposit is made. Any such repurchase or replacement of a Mortgage Loan
shall be on a whole loan, servicing released basis.

            The remedies provided for in this Section 2.03(b) with respect to
any Material Document Defect or Material Breach with respect to any Mortgage
Loan shall apply to the related REO Property.

            If one or more (but not all) of the Mortgage Loans constituting a
Cross-Collateralized Group are to be repurchased or replaced by a Responsible
Party, as contemplated by this Section 2.03, then, prior to the subject
repurchase or substitution, the applicable Master Servicer (or, in the case of a
Specially Serviced Mortgage Loan, the applicable Special Servicer) shall use its
reasonable efforts, subject to the terms of the affected Mortgage Loans, to
prepare and, to the extent necessary and appropriate, have executed by the
related Borrower and record, such documentation as may be necessary to terminate
the cross-collateralization between the Mortgage Loans in such
Cross-Collateralized Group that are to be repurchased or replaced, on the one
hand, and the remaining Mortgage Loans therein, on the other hand, such that
those two groups of Mortgage Loans are each secured only by the Mortgaged
Properties identified in the Mortgage Loan Schedule as directly corresponding
thereto; provided that no such termination shall be effected unless (i) the
Mortgage Loan or Mortgage Loans from such Cross-Collateralized Group that are to
remain part of the Trust Fund have a debt service coverage ratio that is not
less than the greater of (A) the debt service coverage ratio of the
Cross-Collateralized Group, as a collective whole, immediately prior to such
repurchase or replacement and (B) 1.25x and (ii) the loan-to-value ratio with
respect to the Mortgage Loan or Mortgage Loans that are to remain part of the
Trust Fund after the repurchase or replacement of the affected Mortgage Loan is
not greater than the lesser of (A) the loan-to-value ratio of the
Cross-Collateralized Group, as a collective whole, immediately prior to such
repurchase or replacement and (B) 75%; and provided, further, that no such
termination shall be effected unless and until the applicable Master Servicer
and the Trustee have received from a Responsible Party, (i) an Opinion of
Counsel addressed to the Trustee and the applicable Master Servicer from
Independent counsel to the effect that such termination will not cause an
Adverse REMIC Event to occur with respect to the Upper-Tier REMIC, Lower-Tier
REMIC or 622 Third Avenue Loan REMIC or an Adverse Grantor Trust Event with
respect to the Grantor Trust and (ii) written confirmation from each Rating
Agency that such termination will not cause an Adverse Rating Event to occur
with respect to any Class of Rated Certificates; and provided, further, that a
Responsible Party, may, at its option, repurchase or replace the entire
Cross-Collateralized Group without termination of the cross-collateralization.
To the extent necessary and appropriate, the Trustee shall execute (or, subject
to Section 3.10, provide the applicable Master Servicer or Special Servicer with
a limited power of attorney that enables the applicable Master Servicer or
Special Servicer to execute) the loan documentation referred to in the prior
sentence; provided that the Trustee shall not be liable for any misuse of any
such power of attorney by the applicable Master Servicer or Special Servicer.
The applicable Master Servicer shall advance all costs and expenses incurred by
the Trustee and the applicable Master Servicer with respect to any
Cross-Collateralized Group pursuant to this paragraph, and such advances shall
(i) constitute and be reimbursable as Servicing Advances and (ii) be included in
the calculation of Purchase Price for the Mortgage Loan(s) to be repurchased or
replaced. Neither the applicable Master Servicer nor the applicable Special
Servicer shall be liable to any Certificateholder or any other party hereto if
the cross-collateralization of any Cross-Collateralized Group cannot be
terminated as contemplated by this paragraph for any reason beyond the control
of the applicable Master Servicer or the applicable Special Servicer, as the
case may be.

            If the cross-collateralization of any Cross-Collateralized Group of
Mortgage Loans cannot be terminated as contemplated by the preceding paragraph
for any reason (including, but not limited to, the failure of the related
Responsible Party to satisfy any of the conditions set forth in the provisos to
the first sentence of the preceding paragraph), then, for purposes of this
Section 2.03, the related Mortgage Loan Purchase Agreement, and, in the case of
a Cross-Collateralized Group of Column Mortgage Loans, the Column Performance
Guarantee, including for purposes of (i) determining whether the particular
Breach or Document Defect that gave rise to the repurchase/substitution
obligation for such Cross-Collateralized Group is a Material Breach or Material
Document Defect, as the case may be, and (ii) the application of remedies, such
Cross-Collateralized Group shall be treated as a single Mortgage Loan.

            Whenever one or more Replacement Mortgage Loans are substituted for
a Defective Mortgage Loan by a Responsible Party, as contemplated by this
Section 2.03, the applicable Master Servicer or Special Servicer, as applicable,
shall direct the party effecting the substitution to deliver the related
Mortgage File to the Trustee, to certify that such Replacement Mortgage Loan
satisfies or such Replacement Mortgage Loans satisfy, as the case may be, all of
the requirements of the definition of "Qualifying Substitute Mortgage Loan" and
to send such certification to the Trustee. No mortgage loan may be substituted
for a Defective Mortgage Loan as contemplated by this Section 2.03 if the
Mortgage Loan to be replaced was itself a Replacement Mortgage Loan, in which
case, absent a cure of the relevant Material Breach or Material Document Defect,
the affected Mortgage Loan will be required to be repurchased as contemplated
hereby. Monthly Payments due with respect to each Replacement Mortgage Loan (if
any) after the related date of substitution, and Monthly Payments due with
respect to each corresponding Deleted Mortgage Loan (if any) after the related
Due Date in June 2003 and received by the applicable Master Servicer or the
applicable Special Servicer on behalf of the Trust on or prior to the related
date of substitution, shall be part of the Trust Fund. Monthly Payments due with
respect to each Replacement Mortgage Loan (if any) on or prior to the related
date of substitution, and Monthly Payments due with respect to each
corresponding Deleted Mortgage Loan (if any) and received by the applicable
Master Servicer or the applicable Special Servicer on behalf of the Trust after
the related date of substitution, shall not be part of the Trust Fund and are to
be remitted by the applicable Master Servicer to the party effecting the related
substitution promptly following receipt.

            If any Mortgage Loan is to be repurchased or replaced by a
Responsible Party as contemplated by this Section 2.03, the applicable Master
Servicer or Special Servicer, as applicable, shall direct such party to amend
the Mortgage Loan Schedule to reflect the removal of any Deleted Mortgage Loan
and, if applicable, the substitution of the related Replacement Mortgage
Loan(s); and, upon its receipt of such amended Mortgage Loan Schedule, the
applicable Master Servicer or Special Servicer, as applicable, shall deliver or
cause the delivery of such amended Mortgage Loan Schedule to the other parties
hereto. Upon any substitution of one or more Replacement Mortgage Loans for a
Deleted Mortgage Loan, such Replacement Mortgage Loan(s) shall become part of
the Trust Fund and be subject to the terms of this Agreement in all respects.

            In the event that the Master Servicer, the Special Servicer or the
Trustee is notified or otherwise has actual knowledge that Column and KeyBank
have an obligation to repurchase the Great Lakes Crossing Companion Loan from
the Series 2003-CK2 Trust by reason of a "Material Document Defect" or a
"Material Breach" (as such terms are defined in the Series 2003-CK2 PSA), then
such party shall promptly notify the other such parties, and the Master Servicer
shall, as and to the extent contemplated by the Column Mortgage Loan Purchase
Agreement and the KeyBank Mortgage Loan Purchase Agreement, direct Column and
KeyBank to repurchase the Great Lakes Crossing Mortgage Loan at the Purchase
Price contemporaneously with any repurchase of the Great Lakes Crossing
Companion Loan.

            The reasonable "out-of-pocket" costs and expenses incurred by the
applicable Master Servicer, the applicable Special Servicer and/or the Trustee
pursuant to this Section 2.03(b), including reasonable attorney fees and
expenses, shall constitute Servicing Advances to the extent not collected from
the related Responsible Party; provided, that any such "out-of-pocket" costs and
expenses incurred by the applicable Master Servicer or the applicable Special
Servicer and/or the Trustee pursuant to this Section 2.03(b) including
reasonable attorneys' fees and expenses, which constitute Servicing Advances
that arise from the enforcement of a remedy for a Material Breach or Material
Document Defect in accordance with this Section 2.03 by the applicable Master
Servicer or the applicable Special Servicer that relate to the Washington Center
Loan shall not be payable out of or reduce any amounts otherwise distributable
to, any Washington Center Junior Loan.

            (c) Upon receipt of an Officer's Certificate from the applicable
Master Servicer to the effect that the full amount of the Purchase Price or
Substitution Shortfall Amount (as the case may be) for any Mortgage Loan
repurchased or replaced by the related Responsible Party as contemplated by this
Section 2.03 has been deposited in such Master Servicer's Collection Account,
and further, if applicable, upon receipt of the Mortgage File for each
Replacement Mortgage Loan (if any) to be substituted for a Deleted Mortgage
Loan, together with any certifications and/or opinions required pursuant to
Section 2.03(b) to be delivered by the party effecting the
repurchase/substitution, the Trustee shall (i) release or cause the release of
the Mortgage File and any Additional Collateral held by or on behalf of the
Trustee for the Deleted Mortgage Loan to the party effecting the
repurchase/substitution or its designee and (ii) execute and deliver such
endorsements and instruments of release, transfer and/or assignment, in each
case without recourse, as shall be provided to it and are reasonably necessary
to vest in the party effecting the repurchase/substitution or its designee the
legal and beneficial ownership of the Deleted Mortgage Loan (including any
property acquired in respect thereof or proceeds of any insurance policy with
respect thereto) and the related Mortgage Loan Documents, and the applicable
Master Servicer shall notify the affected Borrowers of the transfers of the
Deleted Mortgage Loan(s) and any Replacement Mortgage Loan(s). In connection
with any such repurchase or substitution by the related Responsible Party, each
of the applicable Master Servicer and the applicable Special Servicer shall
deliver to the party effecting the repurchase/substitution or its designee any
portion of the related Servicing File, together with any Escrow Payments,
Reserve Funds and Additional Collateral, held by or on behalf of the applicable
Master Servicer or the applicable Special Servicer, as the case may be, with
respect to the Deleted Mortgage Loan, in each case at the expense of the party
effecting the repurchase/substitution. The Trustee shall notify the related B
Loan Holder or Washington Center Junior Holders, as the case may be, of any
repurchase regarding an A Loan. The reasonable "out-of-pocket" costs and
expenses, including reasonable attorneys' fees and expenses, incurred by the
applicable Master Servicer, the applicable Special Servicer and/or the Trustee
pursuant to this Section 2.03(c), to the extent not collected from the related
Responsible Party, shall be reimbursable to each of them as Servicing Advances
in respect of the affected Mortgage Loan; provided, that any such
"out-of-pocket" costs and expenses incurred by the applicable Master Servicer or
the applicable Special Servicer and/or the Trustee pursuant to this Section
2.03(c) including reasonable attorneys' fees and expenses, which constitute
Servicing Advances that arise from the enforcement of a remedy for a Material
Breach or Material Document Defect in accordance with this Section 2.03 by the
applicable Master Servicer or the applicable Special Servicer that relate to the
Washington Center Loan shall not be payable out of or reduce any amounts
otherwise distributable to, any Washington Center Junior Loan.

            (d) The related Mortgage Loan Purchase Agreement, the Column
Performance Guarantee and/or this Pooling and Servicing Agreement provide the
sole remedies available to the Certificateholders, or the Trustee on their
behalf, respecting any Document Defect or Breach. If, in connection with any
Material Document Defect or Material Breach, each Responsible Party with respect
thereto defaults on its obligations to cure such Material Document Defect or
Material Breach, as the case may be, in all material respects or to repurchase
or replace the affected Mortgage Loan as contemplated by this Section 2.03, or
if, in connection with any repurchase of the Great Lakes Crossing Companion Loan
from the Series 2003-CK2 Trust, Column defaults on its obligation to repurchase
the Great Lakes Crossing Mortgage Loan, then the applicable Master Servicer or
the applicable Special Servicer, as applicable, shall promptly notify the
Trustee and the Controlling Class Representative, and the Trustee shall notify
the Certificateholders. Thereafter, the applicable Master Servicer or the
applicable Special Servicer shall take such actions on behalf of the Trust with
respect to the enforcement of such repurchase/substitution obligations (and if
the applicable Master Servicer or the applicable Special Servicer is notified or
otherwise becomes aware of a default on the part of any Mortgage Loan Seller in
respect of its obligations under the second paragraph of Section 2(c) of the
related Mortgage Loan Purchase Agreement, the applicable Master Servicer or the
applicable Special Servicer shall also take such actions on behalf of the Trust
with respect to the enforcement of such obligations of such Mortgage Loan
Seller), including the institution and prosecution of appropriate legal
proceedings, as the applicable Master Servicer (or, if applicable, the
applicable Special Servicer) shall determine are in the best interests of the
Certificateholders (taken as a collective whole). Any and all reasonable
"out-of-pocket costs and expenses incurred by the applicable Master Servicer,
the applicable Special Servicer and/or the Trustee pursuant to this Section
2.03(d), including, reasonable attorney's fees and expenses, to the extent not
collected from the related Responsible Party, shall constitute Servicing
Advances in respect of the affected Mortgage Loan; provided, that any such
"out-of-pocket" costs and expenses incurred by the applicable Master Servicer or
the applicable Special Servicer and/or the Trustee pursuant to this Section
2.03(d) including reasonable attorneys' fees and expenses, which constitute
Servicing Advances that arise from the enforcement of a remedy for a Material
Breach or Material Document Defect in accordance with this Section 2.03 by the
applicable Master Servicer or the applicable Special Servicer that relate to the
Washington Center Loan shall not be payable out of or reduce any amounts
otherwise distributable to, any Washington Center Junior Loan.

            (e) If the applicable Responsible Party incurs any expense in
connection with the curing of a Breach which also constitutes a default under
the related Mortgage Loan, such Responsible Party shall have a right, and shall
be subrogated to the rights of the Trustee, as successor to the Mortgagee, to
recover the amount of such expenses from the related Borrower; provided,
however, that such Responsible Party's rights pursuant to this Section 2.03(e)
shall be junior, subject and subordinate to the rights of the Trust Fund, the
applicable Master Servicer and the applicable Special Servicer to recover
amounts owed by the related Borrower under the terms of such Mortgage Loan,
including, without limitation, the rights to recover unreimbursed Advances,
accrued and unpaid interest on Advances at the Reimbursement Rate and unpaid or
unreimbursed expenses of the Trust Fund, the applicable Master Servicer or the
applicable Special Servicer allocable to such Mortgage Loan; provided, further,
that in the event and to the extent that such expenses of such Responsible Party
in connection with any Mortgage Loan exceed five percent (5%) of the then
outstanding principal balance of such Mortgage Loan, then such Responsible
Party's rights to reimbursement pursuant to this Section 2.03(e) with respect to
such Mortgage Loan and such excess expenses shall not (without the prior consent
of the applicable Master Servicer or Special Servicer, as applicable, which
shall not be unreasonably withheld) be exercised until the payment in full of
such Mortgage Loan (as such Mortgage Loan may be amended or modified pursuant to
the terms of this Agreement) unless the applicable statute of limitations
requires commencement of any action prior to the payment in full of such
Mortgage Loan. Notwithstanding any other provision of this Agreement to the
contrary, the applicable Master Servicer or, with respect to a Specially
Serviced Mortgage Loan, the applicable Special Servicer, shall not have any
obligation pursuant to this Agreement to collect such reimbursable amounts on
behalf of such Responsible Party; provided, however, that the preceding clause
shall not operate to prevent the applicable Master Servicer or, with respect to
a Specially Serviced Mortgage Loan, the applicable Special Servicer, from using
reasonable efforts, exercised in its sole discretion, to collect such amounts to
the extent consistent with the Servicing Standard. The applicable Responsible
Party may pursue its rights to reimbursement of such expenses directly against
the Borrower, by suit or otherwise, provided that (a) the applicable Master
Servicer or, with respect to a Specially Serviced Mortgage Loan, the applicable
Special Servicer determines in the exercise of its sole discretion consistent
with the Servicing Standard that such actions by such Responsible Party will not
impair such Master Servicer's and/or such Special Servicer's collection or
recovery of principal, interest and other sums due with respect to the related
Mortgage Loan and, if applicable, the related B Loan which would otherwise be
payable to the applicable Master Servicer, the applicable Special Servicer, the
Trustee, and the Certificateholders and, if applicable, the B Loan Holder
pursuant to the terms of this Agreement, (b) such actions will not include an
involuntary bankruptcy, receivership or insolvency proceeding against the
Borrower, (c) such actions will not include the foreclosure or enforcement of
any lien or security interest under the related Mortgage or other Mortgage Loan
Document and (d) such actions will not result in the imposition of an additional
lien against the related Mortgaged Property.

      result in the breach of, any material agreement or other material
      instrument to which it is a party or by which it is bound, which default
      or breach, in the good faith and reasonable judgment of the Depositor, is
      likely to affect materially and adversely either the ability of the

            (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 Depositor, enforceable against the Depositor
      in accordance with the terms hereof, subject to (A) applicable bankruptcy,
      insolvency, reorganization, receivership, moratorium and other laws
      affecting the enforcement of creditors' rights generally, and (B) general

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

            (vi) No consent, approval, authorization or order of any state or
      federal court or governmental agency or body is required for the
      consummation by the Depositor of the transactions contemplated herein,

      2.01(e), which has not yet been completed.

            (vii) The Depositor's transfer of the Original Mortgage Loans to the
      Trustee as contemplated herein requires no regulatory approval, other than
      any such approvals as have been obtained, and is not subject to any bulk

            (viii) The Depositor is not transferring the Original Mortgage Loans
      to the Trustee with any intent to hinder, delay or defraud its present or
      future creditors.

            (ix) The Depositor has been solvent at all relevant times prior to,
      and will not be rendered insolvent by, its transfer of the Original

            (x) After giving effect to its transfer of the Original Mortgage
      Loans to the Trustee, pursuant to Section 2.01(b), the value of the
      Depositor's assets, either taken at their present fair saleable value or
      at fair valuation, will exceed the amount of the Depositor's debts and
      obligations, including contingent and unliquidated debts and obligations
      of the Depositor, and the Depositor will not be left with unreasonably
      small assets or capital with which to engage in and conduct its business.

      or bankruptcy of the Depositor are pending or contemplated.

            (xiii) No litigation is pending or, to the best of the Depositor's

      to the Depositor, would prohibit the Depositor from entering into this
      Agreement or that, in the Depositor's good faith and reasonable judgment,
      is likely to materially and adversely affect either the ability of the
      Depositor to perform its obligations under this Agreement or the financial
      condition of the Depositor.

            (xiv) Immediately prior to the transfer of the Original Mortgage
      Loans to the Trustee for the benefit of the Certificateholders pursuant to
      this Agreement, the Depositor had such right, title and interest in and to
      each Original Mortgage Loan as was transferred to it by the related
      Mortgage Loan Seller pursuant to the related Mortgage Loan Purchase
      Agreement. The Depositor has not transferred any of its right, title and
      interest in and to the Original Mortgage Loans to any Person other than
      the Trustee.

            (xv) The Depositor is transferring all of its right, title and
      interest in and to the Original Mortgage Loans to the Trustee for the
      benefit of the Certificateholders free and clear of any and all liens,
      pledges, charges, security interests and other encumbrances created by or
      through the Depositor.

            (xvi) Except for any actions that are the express responsibility of
      another party hereunder or under any Mortgage Loan Purchase Agreement, and
      further except for actions that the Depositor is expressly permitted to
      complete subsequent to the Closing Date, the Depositor has taken all
      actions required under applicable law to effectuate the transfer of all of
      its right, title and interest in and to the Original Mortgage Loans by the
      Depositor to the Trustee.

            (b) The representations and warranties of the Depositor set forth in

      agreement or other material instrument to which it is a party or by which
      it is bound, which default or breach, in the good faith and reasonable
      judgment of the NCBFSB Master Servicer, is likely to affect materially and
      adversely either the ability of the NCBFSB Master Servicer to perform its
      obligations under this Agreement or the financial condition of the NCBFSB

      consummation by the NCBFSB Master Servicer of the transactions
      contemplated herein, except for those consents, approvals, authorizations
      or orders that previously have been obtained or where the lack of such
      consent, approval, authorization or order would not have a material
      adverse effect on the ability of the NCBFSB Master Servicer to perform its
      obligations under this Agreement.

            (vii) No litigation is pending or, to the best of the NCBFSB Master
      Servicer's knowledge, threatened against the NCBFSB Master Servicer that,

      NCBFSB Master Servicer from entering into this Agreement or that, in the
      NCBFSB Master Servicer's good faith and reasonable judgment, is likely to
      materially and adversely affect either the ability of the NCBFSB Master

party hereto, the party discovering such breach shall give prompt written notice
to each of the other parties hereto.

            (c) Any successor NCBFSB Master Servicer shall be deemed to have
made, as of the date of its succession, each of the representations and
warranties set forth in Section 2.07(a), subject to such appropriate

            (ii) The Co-op Special Servicer's execution and delivery of,
      performance under and compliance with this Agreement will not violate the
      Co-op Special Servicer's organizational documents or constitute a default

      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, which default, in the good faith
      and reasonable judgment of the Co-op Special Servicer, is likely to affect
      materially and adversely either the ability of the Co-op Special Servicer
      to perform its obligations under this Agreement or the financial condition
      of the Co-op Special Servicer.

            (iii) The Co-op Special Servicer has the full corporate power and
      authority to enter into and consummate all transactions involving the

            (v) The Co-op Special Servicer is not in violation of, and its

      any federal, state or local governmental or regulatory authority, which
      violation, in the Co-op Special Servicer's good faith and reasonable
      judgment, is likely to affect materially and adversely either the ability

      Agreement or the financial condition of the Co-op Special Servicer.

            (vi) No consent, approval, authorization or order of any state or

      Co-op Special Servicer's good faith and reasonable judgment, is likely to
      materially and adversely affect either the ability of the Co-op Special
      Servicer to perform its obligations under this Agreement or the financial
      condition of the Co-op Special Servicer.

            (viii) The Co-op Special Servicer has errors and omissions insurance
      in the amounts and with the coverage required by Section 3.07(d).

      party to any Sub-Servicing Agreement providing for the performance of
      duties of the Co-op Special Servicer by any Sub-Servicer with respect to
      any Co-op Mortgage Loans or related REO Properties.

            (b) The representations and warranties of the Co-op Special Servicer
set forth in Section 2.08(a) shall survive the execution and delivery of this

party hereto, the party discovering such breach shall give prompt written notice
to each of the other parties hereto.

            (c) Any successor Co-op Special Servicer shall be deemed to have
made, as of the date of its succession, each of the representations and
warranties set forth in Section 2.08(a), subject to such appropriate

to accurately reflect such successor's jurisdiction of organization and whether

Trustee

      the laws of each State in which any Mortgaged Property is located to the
      extent necessary to ensure the enforceability of each Mortgage Loan
      (insofar as such enforceability is dependent upon compliance by the
      Trustee with such laws) and to perform its obligations under this
      Agreement.

            (ii) The Trustee's execution and delivery of, performance under and
      compliance with this Agreement, will not violate the Trustee's
      organizational documents or constitute a default (or an event which, with
      notice or lapse of time, or both, would constitute a default) under, or
      result in a material breach of, any material agreement or other material
      instrument to which it is a party or by which it is bound, which breach or
      default, in the good faith and reasonable judgment of the Trustee is
      likely to affect materially and adversely either the ability of the
      Trustee to perform its obligations under this Agreement or the financial
      condition of the Trustee.

      is considered in a proceeding in equity or at law.

            (v) The Trustee is not in violation of, and its execution and
      delivery of, performance under and compliance with 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 either the ability of the Trustee to perform its obligations
      under this Agreement or the financial condition of the Trustee.

            (vi) No consent, approval, authorization or order of any state or
      federal court or governmental agency or body is required for the
      consummation by the Trustee of the transactions contemplated herein,
      except for those consents, approvals, authorizations or orders that
      previously have been obtained.

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

            (viii) The Trustee is eligible to act as trustee hereunder in
      accordance with Section 8.06.

            (b) The representations, warranties and covenants of the Trustee set
forth in Section 2.09(a) shall survive the execution and delivery of this
Agreement and shall inure to the benefit of the Persons for whose benefit they
were made for so long as the Trust remains in existence. Upon discovery by any
party hereto of a breach of any such representations, warranties and covenants
that materially and adversely affects the interests of the Certificateholders or
any party hereto, the party discovering such breach shall give prompt written
notice thereof to the other parties hereto.

            (c) Any successor Trustee shall be deemed to have made, as of the
date of its succession, each of the representations and warranties set forth in
Section 2.09(a), subject to such appropriate modifications to the
representation, warranty and covenant set forth in Section 2.09(a)(i) to
accurately reflect such successor's jurisdiction of organization and whether it

of the Certificateholders and, in the case of each A/B Loan Pair, the related B
Loan Holder or Washington Center Junior Holders (as a collective whole), in
accordance with: (i) any and all applicable laws; (ii) the express terms of this
Agreement and the respective Mortgage Loan Documents (and, in the case of each
A/B Loan Pair, the related A/B Intercreditor Agreement); and (iii) to the extent
consistent with the foregoing, the Servicing Standard. Subject to the foregoing,
each Master Servicer and Special Servicer shall each have full power and
authority, acting alone or through Sub-Servicers, 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 Master Servicer (with respect to those Performing Mortgage Loans that it is

Servicer or Special Servicer, as applicable) necessary or appropriate to enable
it to carry out its servicing and administrative duties hereunder; provided,
that the Trustee shall not be held liable for any misuse of any such power of
attorney by any Master Servicer or Special Servicer.

            (c) The parties hereto acknowledge that, pursuant to the Great Lakes
Crossing Intercreditor Agreement: (i) until the occurrence of a Great Lakes
Crossing Change of Servicing Control Event, the Great Lakes Crossing Total Loan
is to be serviced and administered by the Series 2003-CK2 Master Servicer and
the Series 2003-CK2 Special Servicer in accordance with the Series 2003-CK2 PSA
(provided that the Master Servicer is responsible for performing such services
with respect to the Great Lakes Crossing Mortgage Loan as are specifically set
forth in Articles I through XI of this Agreement); and (ii) upon the occurrence
of a Great Lakes Crossing Change of Servicing Control Event, the Great Lakes
Crossing Total Loan will be serviced and administered by the Master Servicer and
Special Servicer in accordance with Article XII of this Agreement; provided
that, if the Series 2003-CK2 PSA is ever to be replaced by any other Great Lakes
Crossing Servicing Agreement, then prior to exercising any consent right that
the Trustee may have with respect to that successor Great Lakes Crossing
Servicing Agreement, the Trustee shall obtain written confirmation from each
Rating Agency that such successor Great Lakes Crossing Servicing Agreement will
not result in an Adverse Rating Event with respect to any Class of Rated
Certificates.

            For so long as (i) the Great Lakes Crossing Mortgage Loan or any
Great Lakes Crossing REO Mortgage Loan are part of the Mortgage Pool and (ii)
the Great Lakes Crossing Total Loan and/or any Great Lakes Crossing REO Property
are being serviced and administered under any Great Lakes Crossing Servicing
Agreement, the Master Servicer shall use reasonable efforts to monitor the
performance and, to the extent that it has standing to do so, enforce the
obligations of the Great Lakes Crossing Master Servicer and the Great Lakes
Crossing Special Servicer, respectively, under such Great Lakes Crossing
Servicing Agreement. Such enforcement, including the legal prosecution of claims
and the pursuit of other appropriate remedies, shall be in such form and carried
out to such an extent and at such time as the Master Servicer, in its reasonable
judgment, would require were it the owner of the Great Lakes Crossing Mortgage
Loan. The reasonable costs and expenses incurred by the Master Servicer in
connection with such enforcement shall be paid by, and reimbursable as,
Servicing Advances.

            (d) The relationship of each of the Master Servicers and the Special
Servicers to the Trustee and, unless they are the same Person, each other under
this Agreement is intended by the parties to be that of an independent
contractor and not that of a joint venturer, partner or, except as specifically
set forth herein, agent.

            (e) Pursuant to the A/B Intercreditor Agreement for the 622 Third
Avenue Loan and the Washington Center Loan, the owners of the 622 Third Avenue B
Loan and the Washington Center Junior Loans, respectively, have agreed that the
Master Servicer and the related Special Servicer are authorized and obligated to
service and administer the 622 Third Avenue B Loan and the Washington Center
Junior Loans pursuant to this Agreement. The Master Servicer shall be entitled,
during any period when the 622 Third Avenue Total Loan and the Washington Center
Total Loan do not constitute Specially Serviced Mortgage Loans, to exercise the
rights and powers granted under the related A/B Intercreditor Agreement to the
"Lead Lender" and/or the "Servicer" referred to therein subject to the
limitations of such A/B Intercreditor Agreement and to the rights and powers of
the holder of the 622 Third Avenue B Loan and the Washington Center Junior Loans
under such A/B Intercreditor Agreement. For the avoidance of doubt, the parties
acknowledge that neither the Master Servicer nor the related Special Servicer
shall be entitled or required to exercise the rights and powers granted to the
"Note B Holder" or the "Note C Holder" as defined under the related A/B
Intercreditor Agreement. The parties hereto acknowledge (A) section 3(a) of the
Washington Center Intercreditor Agreement, (B) section 3(a) of the Washington
Center Intercreditor Agreement provides (in part) that "...any such differences
between this Agreement and such Servicing Agreement shall not (x) have a
material adverse effect on any of the rights, remedies or protections granted to
the Holders under this Agreement (without giving effect to any provision of this
Agreement which states that a term shall have "the meaning assigned to such term
in the Servicing Agreement," or be "subject to the Servicing Agreement" or
similar phrases) or under the form attached hereto as Exhibit D, or (y) without
limiting the generality of the foregoing, have an adverse effect on the Note B
Holder or the Note C Holder with respect to the definitions of Servicing Fee,
Special Servicing Fee, Liquidation Fee, Workout Fee, Default Charges, Additional
Servicing Compensation Costs, Specially Serviced Mortgage Loan, Appraisal
Reduction Amount or Controlling Class Holder or diminish the rights of the
Servicers to transfer servicing compensation as set forth in Exhibit D or (z)
diminish or impair any of the rights granted to any Junior Holder under Section
20."; provided, that any such defined terms in this subsection (B) shall have
the meanings assigned to such terms in the Washington Center Intercreditor
Agreement and (C) the Washington Center Junior Holders have had the opportunity
to review and comment on this Agreement.

            (f) In the event that an A/B Material Default occurs with respect to
any CBA A/B Loan Pair, and for so long as such A/B Material Default shall be
continuing, the Master Servicer and/or the Special Servicer, as applicable,
shall be obligated to service, subject to the terms and conditions of the
related A/B Intercreditor Agreement, the related CBA B Loan, on behalf of the
related B Loan Holder, and all references herein to "Mortgage Loan" (and, if the
related A Loan is a Specially Serviced Mortgage Loan, all references herein to
"Specially Serviced Mortgage Loan"), other than provisions pertaining to the
making of Advances, shall include the B Loan that is being serviced under this
Agreement.

            Section 3.02 Collection of Mortgage Loan Payments

            (a) The applicable Master Servicer (with respect to Performing
Mortgage Loans) and the applicable Special Servicer (with respect to each
Specially Serviced Mortgage Loans) shall undertake reasonable efforts to collect
all payments called for under the terms and provisions of the Mortgage Loans and
shall follow such collection procedures as are consistent with applicable law,
the express terms of this Agreement, the related Mortgage Loan Documents, in the
case of any B Loan or Washington Center Junior Loan, the related A/B
Intercreditor Agreement and, to the extent consistent with the foregoing, the
Servicing Standard; provided that neither such Master Servicer nor such Special
Servicer shall, with respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, take any enforcement action with respect to the payment of
Post-ARD Additional Interest (other than the making of requests for its
collection), unless (i) the taking of an enforcement action with respect to the
payment of other amounts due under such Mortgage Loan is, in the reasonable
judgment of the applicable Special Servicer, and without regard to such Post-ARD
Additional Interest, also necessary, appropriate and consistent with the
Servicing Standard or (ii) all other amounts due under such Mortgage Loan have
been paid, the payment of such Post-ARD Additional Interest has not been
forgiven in accordance with Section 3.20 and, in the reasonable judgment of the
applicable Special Servicer, the Liquidation Proceeds expected to be recovered
in connection with such enforcement action will cover the anticipated costs of
such enforcement action and, if applicable, any associated Advance Interest.
Consistent with the foregoing, the applicable Master Servicer (as to Performing
Mortgage Loans), and the applicable Special Servicer (as to Specially Serviced
Mortgage Loans), each may waive any Default Charges in connection with any
specific delinquent payment on a Mortgage Loan it is obligated to service
hereunder; provided that, to the extent the applicable Master Servicer (as to
Performing Mortgage Loans) and the applicable Special Servicer (as to Specially
Serviced Mortgage Loans) waives any Default Charges, any outstanding interest on
Advances and Additional Trust Fund Expenses with respect to the related Mortgage
Loan that would otherwise have been paid out of such Default Charges shall be
paid out of the Additional Master Servicing Compensation payable to such Master
Servicer or Additional Special Servicing Compensation payable to such Special
Servicer, as the case may be, with respect to that Mortgage Loan; and provided,
further, that if no Additional Master Servicing Compensation or Additional
Special Servicing Compensation, as applicable, is available to offset the
outstanding Advance Interest, property inspection costs and other Additional
Trust Fund Expenses with respect to the Mortgage Loan that would otherwise be
offset by the Default Charges, then the applicable Master Servicer or the
applicable Special Servicer, as the case may be, shall not waive such Default
Charges unless (i) except with respect to the Washington Center Total Loan, it
is the first such waiver with respect to the subject Mortgage Loan under such
circumstances (regardless of whether such first waiver is made by the applicable
Master Servicer or the applicable Special Servicer), or (ii) in the case of a
Performing Mortgage Loan, the applicable Master Servicer has obtained the
consent of the Special Servicer (which consent shall be deemed given if the
applicable Special Servicer does not disapprove such waiver within ten (10)
Business Days) which has, as and to the extent contemplated by Section 3.24,
obtained the consent of the Controlling Class Representative, or (iii) in the
case of a Specially Serviced Mortgage Loan, the Special Servicer has, as and to
the extent contemplated by Section 3.24, obtained the consent of the Controlling
Class Representative.

            (b) At least ninety days prior to the maturity date of each Balloon
Mortgage Loan, the applicable Master Servicer shall send a notice to the related
Borrower of such maturity date (with a copy to be sent to the applicable Special
Servicer) and shall request confirmation that the Balloon Payment will be paid
by such maturity date; provided that if the Master Servicer has not received
such confirmation, the Master Servicer shall send a second notice at least 60
days prior to such maturity date, and a third notice at least 30 days prior to
such maturity date.

            (c) Promptly following the Closing Date, the Trustee shall send
written notice to the Series 2003-CK2 Master Servicer and the Series 2003-CK2
Trustee stating that, as of the Closing Date, the Trustee is the holder of the
Great Lakes Crossing Mortgage Loan and directing the Series 2003-CK2 Master
Servicer to remit to the Master Servicer all amounts payable to, and to forward,
deliver or otherwise make available, as the case may be, to the Master Servicer
all reports, statements, documents, communications and other information that
are to be forwarded, delivered or otherwise made available to, the holder of the
Great Lakes Crossing Mortgage Loan under the Great Lakes Crossing Intercreditor
Agreement and the Series 2003-CK2 PSA. In the event that the Series 2003-CK2 PSA
is replaced by another Great Lakes Crossing Servicing Agreement and a
Responsible Officer of the Trustee is aware of such replacement, then the
Trustee shall promptly send a comparable written notice to the then holder of
the Great Lakes Crossing Companion Loan and to the Great Lakes Crossing Master
Servicer under such new Great Lakes Crossing Servicing Agreement. The Master
Servicer shall, on the day of receipt thereof, deposit into the Collection
Account all amounts received by it from the Great Lakes Crossing Master Servicer
or any other party under any Great Lakes Crossing Servicing Agreement with
respect to the Great Lakes Crossing Mortgage Loan, the Great Lakes Crossing
Mortgaged Property or any Great Lakes Crossing REO Property. In the event the
Master Servicer fails to so receive any amounts due to the holder of the Great
Lakes Crossing Mortgage Loan during any calendar month under the Great Lakes
Crossing Intercreditor Agreement and any Great Lakes Crossing Servicing
Agreement by 2:00 p.m. (New York City time) on the Master Servicer Remittance
Date in such calendar month, the Master Servicer shall (i) notify the Great
Lakes Crossing Master Servicer or other applicable party responsible for making
such remittances, as well as the holder of the Great Lakes Crossing Companion
Loan, that such amounts due with respect to the Great Lakes Crossing Mortgage
Loan have not been received (specifying the amount of such deficiency) and (ii)
if and to the extent that the amount in question is a Monthly Payment or Assumed
Monthly Payment with respect to the Great Lakes Crossing Mortgage Loan or any
Great Lakes Crossing REO Mortgage Loan, make a P&I Advance (to the extent such
P&I Advance is not a Nonrecoverable Advance) with respect to such amounts as
required by the terms of this Agreement in accordance with Section 4.03.
Further, in accordance with Section 4.03, in the event the Master Servicer fails
to make such P&I Advance with respect to the Great Lakes Crossing Mortgage Loan
or any Great Lakes Crossing REO Mortgage Loan, then the Trustee shall make such
P&I Advance.

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

            (a) Each Master Servicer shall establish and maintain one or more
accounts ("Servicing Accounts"), in which all Escrow Payments received by it
with respect to the Mortgage Loans shall be deposited and retained. The General
Master Servicer shall maintain the Servicing Accounts with respect to the
General Mortgage Loans (including any such Mortgage Loans that are Specially
Serviced Mortgage Loans), and the NCBFSB Master Servicer shall maintain the
Servicing Accounts with respect to the NCBFSB Mortgage Loans (including any such
Mortgage Loans that are Specially Serviced Mortgage Loans). Subject to any terms
of the related Mortgage Loan Documents and the terms of any related A/B
Intercreditor Agreement that specify the nature of the account in which Escrow
Payments shall be held, each Servicing Account shall be an Eligible Account. As
and to the extent consistent with the Servicing Standard, applicable law and the
related Mortgage Loan Documents, each Master Servicer may make withdrawals from
the Servicing Accounts maintained by it, and may apply Escrow Payments held
therein with respect to any Mortgage Loan (together with interest earned
thereon), only as follows: (i) to effect the payment of real estate taxes,
assessments, insurance premiums (including, premiums on any Environmental
Insurance Policy), ground rents (if applicable) and comparable items in respect
of the related Mortgaged Property; (ii) to reimburse such Master Servicer, such
Special Servicer, the Trustee or any Fiscal Agent, as applicable, for any
unreimbursed Servicing Advances made thereby with respect to such Mortgage Loan
to cover any of the items described in the immediately preceding clause (i);
(iii) to refund to the related Borrower any sums as may be determined to be
overages; (iv) to pay interest or other income, if required and as described
below, to the related Borrower on balances in the Servicing Account (or, if and
to the extent not payable to the related Borrower to pay such interest or other
income (up to the amount of any Net Investment Earnings in respect of such
Servicing Account for each Collection Period) to the applicable Master
Servicer); (v) after an event of default, to pay the principal of, accrued
interest on and any other amounts payable with respect to such Mortgage Loan; or
(vi) to clear and terminate the Servicing Account at the termination of this
Agreement in accordance with Section 9.01. The applicable Master Servicer shall
pay or cause to be paid to the related Borrowers interest and other income, if
any, earned on the investment of funds in Servicing Accounts maintained thereby,
if and to the extent required by law or the terms of the related Mortgage Loan
Documents. If the applicable Master Servicer shall deposit in a Servicing
Account any amount not required to be deposited therein, it may at any time
withdraw such amount from such Servicing Account, any provision herein to the
contrary notwithstanding. Promptly after any Escrow Payments are received by the
applicable Special Servicer from any Borrower, and in any event within two
Business Days after any such receipt, such Special Servicer shall remit such
Escrow Payments to a Master Servicer for deposit in the applicable Servicing
Account(s).

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

            (c) In accordance with the Servicing Standard, but subject to
Section 3.11(h), the applicable Master Servicer shall make a Servicing Advance
with respect to each Mortgaged Property (including each Mortgaged Property
relating to a Specially Serviced Mortgage Loan and each Mortgaged Property that
secures an A/B Loan Pair, provided that the applicable Master Servicer shall not
be obligated to make such a Servicing Advance with respect to an A/B Loan Pair
after the principal balance of the related A Loan is zero) all such funds as are
necessary for the purpose of effecting the timely payment of (i) real estate
taxes, assessments and other similar items, (ii) ground rents (if applicable),
and (iii) premiums on Insurance Policies (including, premiums on any
Environmental Insurance Policy), in each instance prior to the applicable
penalty or termination date if and to the extent that (x) Escrow Payments (if
any) collected from the related Borrower are insufficient to pay such item when
due, and (y) the related Borrower has failed to pay such item on a timely basis;
provided that, in the case of amounts described in the preceding clause (i), the
applicable Master Servicer shall not make a Servicing Advance of any such amount
if such Master Servicer reasonably anticipates (in accordance with the Servicing
Standard) that such amounts will be paid by the related Borrower on or before
the applicable penalty date, in which case such Master Servicer shall use its
best efforts consistent with the Servicing Standard to confirm whether such
amounts have been paid and, subject to Section 3.11(h), shall make a Servicing
Advance of such amounts, if necessary, not later than five Business Days
following confirmation by such Master Servicer that such amounts have not been
paid by the applicable penalty date. All such Advances shall be reimbursable in
the first instance from related collections from the Borrowers and further as
provided in Section 3.05(a). No costs incurred by the applicable Master Servicer
in effecting the payment of real estate taxes, assessments and, if applicable,
ground rents on or in respect of such Mortgaged Properties shall, for purposes
hereof, including calculating monthly distributions to Certificateholders, be
added to the respective unpaid principal balances or Stated Principal Balances
of the related Mortgage Loans, notwithstanding that the terms of such Mortgage
Loans so permit; provided that this sentence shall not be construed to limit the
rights of such Master Servicer or the applicable Special Servicer on behalf of
the Trust to enforce any obligations of the related Borrower under such Mortgage
Loan.

            (d) Each Master Servicer shall establish and maintain, as
applicable, one or more accounts (the "Reserve Accounts"), in which all Reserve
Funds, if any, received by it with respect to the Mortgage Loans as to which it
is the applicable Master Servicer, shall be deposited and retained. The General
Master Servicer shall maintain the Reserve Accounts with respect to all of the
Mortgage Loans (other than the NCBFSB Serviced Mortgage Loans), and the NCBFSB
Master Servicer shall maintain the Reserve Accounts with respect to the NCBFSB
Serviced Mortgage Loans. Subject to any terms of the related Mortgage Loan
Documents that specify the nature of the account in which Reserve Funds shall be
held, each Reserve Account shall be an Eligible Account. As and to the extent
consistent with the Servicing Standard, applicable law and the related Mortgage
Loan Documents, each Master Servicer may make withdrawals of amounts so
deposited, and draws under any Letter of Credit delivered in lieu of Reserve
Funds, (i) to pay for, or to reimburse the related Borrower in connection with,
the costs associated with the related tenant improvements, leasing commissions,
repairs, replacements, capital improvements and/or environmental testing and
remediation, litigation and/or other special expenses at or with respect to the
related Mortgaged Property for which such Reserve Funds were intended and to
refund the related Borrower any sums as may be determined to be overages; (ii)
in the case of Reserve Funds intended to cover debt service payments, to apply
amounts on deposit therein in respect of principal and interest on such Mortgage
Loan; (iii) to reimburse such Master Servicer, either Special Servicer, the
Trustee or any Fiscal Agent, as applicable, for any unreimbursed Advances
(together with any related Advance Interest) made thereby with respect to such
Mortgage Loan to cover any of the items described in the immediately preceding
clauses (i) and (ii); (iv) to release such Reserve Funds to the related Borrower
if the conditions precedent for such release are satisfied or, in the case of
Earn-Out Reserve Funds, to otherwise apply such Reserve Funds in accordance with
the related Mortgage Loan Documents if the conditions precedent for such release
are not satisfied, including any requirements set forth in this Agreement; (v)
to pay interest or other income, if required and as described below, to the
related Borrower on balances in the Reserve Account (or, if and to the extent
not payable to the related Borrower, to pay such interest or other income (up to
the amount of any Net Investment Earnings in respect of such Reserve Account for
each Collection Period) to such Master Servicer); (vi) after an event of
default, to pay the principal of, accrued interest on and any other amounts
payable with respect to such Mortgage Loan; or (vii) to clear and terminate the
Reserve Account at the termination of this Agreement in accordance with Section
9.01. If the Borrower under any Mortgage Loan delivers a Letter of Credit in
lieu of Reserve Funds, then the applicable Master Servicer shall make draws on
such Letter of Credit at such times and for such purposes as it would have made
withdrawals from a Reserve Account and, to the extent consistent with the
Servicing Standard, applicable law and the related Mortgage Loan Documents, in
order to convert the amount of such Letter of Credit into Reserve Funds.
Notwithstanding the foregoing, no Master Servicer shall release any Earn-Out
Reserve Funds, or return any related Letter of Credit delivered in lieu of
Earn-Out Reserve Funds, to the related Borrower, unless and until: (i) such
Master Servicer has so notified the applicable Special Servicer in writing and
has provided such Special Servicer with any written or electronic information in
such Master Servicer's possession regarding such Mortgage Loan or the related
Mortgaged Property that such Special Servicer may reasonably request within ten
Business Days of receiving such written notice; and (ii) subject to Section 3.24
the applicable Special Servicer has consented to such release of any such
Earn-Out Reserve Funds or return of any related Letter of Credit (such consent
to be given or withheld in accordance with the Servicing Standard and to be
deemed given if the applicable Special Servicer does not object in writing to
such release of any such Earn-Out Reserve Funds or return of any such Letter of
Credit within ten Business Days after receiving such additional information from
the applicable Master Servicer (or, if it did not request additional
information, within ten Business Days after receiving such notice)). Each Master
Servicer shall pay or cause to be paid to the relevant Borrowers interest and
other income, if any, earned on the investment of funds in Reserve Accounts
maintained thereby, if and to the extent required by law or the terms of the
related Mortgage Loan Documents. If a Master Servicer shall deposit in a Reserve
Account maintained by it any amount not required to be deposited therein, it may
at any time withdraw such amount from such Reserve Account, any provision herein
to the contrary notwithstanding. Promptly after any Reserve Funds are received
by a Special Servicer from any Borrower, and in any event within two Business
Days of such receipt, such Special Servicer shall remit such Reserve Funds to
the applicable Master Servicer for deposit in the applicable Reserve Account(s).
Any out-of-pocket expenses, including reasonable attorneys' fees and expenses,
incurred by the applicable Master Servicer or Special Servicer to enable such
Master Servicer or Special Servicer, as the case may be, to make any draw under
any Letter of Credit shall constitute a Servicing Advance, and such Master
Servicer or Special Servicer, as the case may be, shall make reasonable efforts
to recover such expenses from the related Borrower to the extent the Borrower is
required to pay such expenses under the terms of the related Mortgage Loan.

            (e) To the extent an operations and maintenance plan is required to
be established and executed pursuant to the terms of a Mortgage Loan, the
applicable Master Servicer shall request from the related Borrower 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 other action or remediation with respect to
environmental matters is required to have been taken or completed pursuant to
the terms of a Mortgage Loan, the applicable Master Servicer shall request from
the related Borrower written confirmation of such action 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 have been taken or completed. To the
extent that a Borrower shall fail to promptly respond to any inquiry described
in this Section 3.03(e), the applicable Master Servicer shall notify the
Trustee, the applicable Special Servicer, the Controlling Class Representative,
the 622 Third Avenue B Loan Holder (with respect to the 622 Third Avenue Loan)
and each Washington Center Junior Holder (with respect to the Washington Center
Loan). The applicable Master Servicer shall promptly notify the Trustee, the
applicable Special Servicer and the Controlling Class Representative if the
Master Servicer shall determine that any Borrower under any Mortgage Loan has
failed to perform its obligations under the related Mortgage Loan in respect of
environmental matters.

            (f) Subject to applicable law and the terms of the related Mortgage
Loan Documents, funds in the Servicing Accounts and the Reserve Accounts may be
invested only in Permitted Investments in accordance with the provisions of
Section 3.06.

            Section 3.04 Collection Accounts, Distribution Account, Interest
Reserve Account and Excess Liquidation Proceeds Account

            (a) Each of the Master Servicers shall segregate and hold all funds
collected and received by it in connection with the Mortgage Pool separate and
apart from its own funds and general assets. In connection therewith, each
Master Servicer shall establish and maintain one or more segregated accounts
(collectively, the "Collection Account"), in which the funds described below are
to be deposited and held on behalf of the Trustee in trust for the benefit of
the Certificateholders. Each account that constitutes the Collection Account
shall be an Eligible Account. Each Master Servicer shall deposit or cause to be
deposited in the applicable Collection Account, within one Business Day of
receipt by it (in the case of payments by Borrowers or other collections on the
Mortgage Loans as to which it acts as Master Servicer) or as otherwise required
hereunder, the following payments and collections received or made by or on
behalf of such Master Servicer in respect of the Mortgage Pool subsequent to the
Closing Date with respect to the Mortgage Loans and REO Properties as to which

before their respective Due Dates in June 2003 (or, in the case of a Replacement
Mortgage Loan, on or before the related date of substitution), which payments
shall be delivered promptly to the related Mortgage Loan Seller or its designee,
with negotiable instruments endorsed as necessary and appropriate without
recourse):

            (i) all payments, from whatever source, or transfers from a debt
      service reserve account, on account of principal of the Mortgage Loans and
      any B Loan or C Loan, including Principal Prepayments;

            (ii) all payments, from whatever source, or transfers from a debt
      service reserve account, on account of interest on the Mortgage Loans and
      any B Loan or C Loan, including Default Interest and Post-ARD Additional
      Interest;

            (iii) all Prepayment Premiums, Yield Maintenance Charges and late

            (iv) all Insurance Proceeds, Condemnation Proceeds and Liquidation
      Proceeds received in respect of the Serviced Mortgage Loans;

            (v) all remittances to the Trust under a Great Lakes Crossing
      Servicing Agreement with respect to the Great Lakes Crossing Mortgage Loan
      or any Great Lakes Crossing REO Property;

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

            (vii) any amounts required to be deposited by the Master Servicer or

      resulting from a deductible clause in a blanket or master force placed
      hazard insurance policy;

            (viii) any amounts required to be transferred from (A) any REO
      Account pursuant to Section 3.16(c), (B) an A/B Loan Pair Custodial
      Account pursuant to Section 3.04(f) or (C) any Great Lakes Crossing
      Custodial Account pursuant to Section 12.04(b);

            (ix) insofar as they do not constitute Escrow Payments or Reserve
      Funds, any amounts paid by a Borrower specifically to cover items for
      which a Servicing Advance has been made or that represent a recovery of
      property protection expenses from a Borrower;

            (x) any amounts received pursuant to Section 3.18 in connection with
      the liquidation of a Specially Designated Defaulted Mortgage Loan or
      pursuant to Section 3.09 in connection with the liquidation of a Defaulted
      Mortgage Loan;

            (xi) any amounts paid by a Mortgage Loan Seller or the Column
      Performance Guarantor, as the case may be, in connection with the
      repurchase or substitution of a Mortgage Loan by such party pursuant to
      Section 2.03;

            (xii) any amounts paid to purchase or otherwise acquire all the
      Mortgage Loans and any REO Properties in connection with the termination
      of the Trust Fund pursuant to Section 9.01; and

            (xiii) any amounts paid by the B Loan Holder or any Washington
      Center Junior Holder or mezzanine lender in respect of the related A Loan
      in connection with any cure or purchase option exercised pursuant to the
      terms of the A/B Intercreditor Agreement, or related intercreditor
      agreement, as applicable.

            The foregoing requirements for deposit in the Collection Account
shall be exclusive. Without limiting the generality of the foregoing, actual
payments from Borrowers in the nature of Escrow Payments, assumption fees,
assumption application fees, defeasance fees, earn-out fees, extension fees,
modification fees, charges for beneficiary statements or demands, amounts
collected for checks returned for insufficient funds and other fees and amounts
collected from Borrowers that constitute Additional Master Servicing
Compensation and/or Additional Special Servicing Compensation, need not be
deposited by either Master Servicer in its Collection Account. Each Master
Servicer shall promptly deliver to the Special Servicer any of the foregoing
items received by it, if and to the extent that such items constitute Additional
Special Servicing Compensation. If either Master Servicer shall deposit in its
Collection Account any amount not required to be deposited therein, it may at
any time withdraw such amount from such Master Servicer's Collection Account,
any provision herein to the contrary notwithstanding.

            Upon receipt of any of the amounts described in clauses (i) through
(v), (viii) or (ix) through (xiii) of the first paragraph of this Section
3.04(a) with respect to any Mortgage Loan, each Special Servicer shall promptly,
but in no event later than one Business Day after receipt, remit such amounts to
the applicable Master Servicer for deposit into the Collection Account, unless
such Special Servicer determines, consistent with the Servicing Standard, that a
particular item should not be deposited because of a restrictive endorsement.
With respect to any such amounts paid by check to the order of such Special
Servicer, such Special Servicer shall endorse such check to the order of the
applicable Master Servicer (in its capacity as such), without recourse,
representation or warranty, unless the applicable Special Servicer determines,
consistent with the Servicing Standard, that a particular item cannot be so
endorsed and delivered because of a restrictive endorsement. Any such amounts
received by a Special Servicer with respect to an REO Property shall be
deposited by such Special Servicer into the REO Account and remitted to the
applicable Master Servicer for deposit into such Master Servicer's Collection
Account pursuant to Section 3.16(c) (or, if such REO Property relates to an A/B
Loan Pair, into the related A/B Loan Pair Custodial Account).

            (b) The Trustee shall establish and maintain one or more segregated
accounts (collectively, the "Distribution Account"), to be held in trust for the
benefit of the Certificateholders. Each account that constitutes the
Distribution Account shall be an Eligible Account. By 1:00 p.m. (New York City
time) on each Master Servicer Remittance Date, each Master Servicer shall
deliver to the Trustee, for deposit in the Distribution Account, an aggregate
amount of immediately available funds equal to each Master Servicer's Master
Servicer Remittance Amount with respect to such Master Servicer for such Master
Servicer Remittance Date. Immediately upon deposit of any Master Servicer
Remittance Amount for any Master Servicer Remittance Date into the Distribution
Account, any portion thereof that represents any Post-ARD Additional Interest
related to the ARD Mortgage Loans shall be deemed to have been deposited into
the Post-ARD Additional Interest Distribution Account, and the remaining portion
thereof shall be deemed to have been deposited into the Lower-Tier Distribution
Account or, with respect to the 622 Third Avenue Loan, into the 622 Third Avenue
Loan REMIC Distribution Account. In addition, each Master Servicer shall, as and
when required hereunder, deliver to the Trustee for deposit in the Lower-Tier
Distribution Account or, with respect to the 622 Third Avenue Loan, into the 622
Third Avenue Loan REMIC Distribution Account, any P&I Advances and Compensating
Interest Payments required to be made by such Master Servicer hereunder.
Furthermore, any amounts paid by any party hereto to indemnify the Trust Fund
pursuant to any provision hereof shall be delivered to the Trustee for deposit
in the Lower-Tier Distribution Account. The Trustee shall, upon receipt, deposit
in the Lower-Tier Distribution Account or, with respect to the 622 Third Avenue
Loan, into the 622 Third Avenue Loan REMIC Distribution Account any and all
amounts received or, pursuant to Section 4.03, advanced by the Trustee or any
Fiscal Agent that are required by the terms of this Agreement to be deposited
therein. As and when required pursuant to Section 3.05(c), the Trustee shall
transfer Interest Reserve Amounts in respect of the Interest Reserve Mortgage
Loans from the Interest Reserve Account to the Lower-Tier Distribution Account
or, with respect to the 622 Third Avenue Loan, into the 622 Third Avenue Loan
REMIC Distribution Account. The Trustee shall also deposit in the Distribution
Account any amounts required to be deposited by the Trustee pursuant to Section
3.06 in connection with losses incurred with respect to Permitted Investments of
funds held in the Distribution Account. Furthermore, as and when required
pursuant to Section 3.05(d), the Trustee shall transfer monies from the Excess
Liquidation Proceeds Account to the Lower-Tier Distribution Account or, with
respect to the 622 Third Avenue Loan, into the 622 Third Avenue Loan REMIC
Distribution Account. If the Trustee shall deposit in the Lower-Tier
Distribution Account or, with respect to the 622 Third Avenue Loan, into the 622
Third Avenue Loan REMIC Distribution Account, any amount not required to be
deposited therein, it may at any time withdraw such amount from the Lower-Tier
Distribution Account or the 622 Third Avenue Loan REMIC Distribution Account, as
applicable, any provision herein to the contrary notwithstanding.

            On each Distribution Date, the Trustee 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 Section 4.01.

            Any amounts deposited in accordance with this Section 3.04(b) that
represent amounts deposited in respect of the 622 Third Avenue Loan REMIC shall
be deemed to be distributed in respect of the 622 Third Avenue Loan REMIC
Regular Interests and 622 Third Avenue Loan REMIC Residual Interest as set forth
herein.

            (c) The Trustee shall establish and maintain one or more accounts
(collectively, the "Interest Reserve Account") to be held in trust for the
benefit of the Certificateholders. Each account that constitutes the Interest
Reserve Account shall be an Eligible Account. On the Distribution Date in
January (except during a leap year) and February of each calendar year,
commencing in 2004, prior to any distributions being made in respect of the
Certificates on such Distribution Date, the Trustee shall, with respect to each
Interest Reserve Mortgage Loan, withdraw from the Distribution Account and
deposit in the Interest Reserve Account an amount equal to the Interest Reserve
Amount, if any, in respect of such Interest Reserve Mortgage Loan for such
Distribution Date; provided that no such transfer of monies from the
Distribution Account to the Interest Reserve Account shall be made on the Final
Distribution Date. The Trustee shall also deposit in the Interest Reserve
Account any amounts required to be deposited by the Trustee pursuant to Section
3.06 in connection with losses incurred with respect to Permitted Investments of
funds held in the Interest Reserve Account.

            (d) If any Excess Liquidation Proceeds are received, the Trustee
shall establish and maintain one or more accounts (collectively, the "Excess
Liquidation Proceeds Account") to be held in trust for the benefit of the
Certificateholders. Each account that constitutes the Excess Liquidation
Proceeds Account shall be an Eligible Account. On each Master Servicer
Remittance Date, each Master Servicer shall withdraw from its Collection Account
and remit to the Trustee for deposit in the Excess Liquidation Proceeds Account
all Excess Liquidation Proceeds received by it during the Collection Period
ending on the Determination Date immediately prior to such Master Servicer
Remittance Date; provided, however, that if such Excess Liquidation Proceeds
relate to an A/B Loan Pair, the amount allocable to the related B Loan or the
Washington Center Junior Loans, as the case may be, shall be deposited in the
A/B Loan Pair Custodial Account. The Trustee shall also deposit in the Excess
Liquidation Proceeds Account any amounts required to be deposited by the Trustee
pursuant to Section 3.06 in connection with losses incurred with respect to
Permitted Investments of funds held in the Excess Liquidation Proceeds Account.
Any Excess Liquidation Proceeds received in respect of the 622 Third Avenue Loan
shall be deemed to be distributed in respect of the 622 Third Avenue Loan REMIC
Residual Interest and immediately deposited in the Excess Liquidation Proceeds
Account.

            (e) Funds in a Collection Account, the Upper-Tier Distribution
Account, the Lower-Tier Distribution Account, the 622 Third Avenue Loan REMIC
Distribution Account, the Post-ARD Additional Interest Distribution Account, the
Interest Reserve Account and/or the Excess Liquidation Proceeds Account may be
invested in Permitted Investments in accordance with the provisions of Section
3.06. Each Master Servicer shall give notice to the other parties hereto of the
location of its Collection Account as of the Closing Date and of the new
location of its Collection Account prior to any change thereof. The Upper-Tier
Distribution Account, the Lower-Tier Distribution Account, the 622 Third Avenue
Loan REMIC Distribution Account, the Post-ARD Additional Interest Distribution
Account, Interest Reserve Account and Excess Liquidation Proceeds Account shall
each be established at the Corporate Trust Office of the Trustee as of the
Closing Date, and the Trustee shall give notice to the other parties hereto of
the new location of each of the Upper-Tier Distribution Account, Lower-Tier
Distribution Account, the 622 Third Avenue Loan REMIC Distribution Account, the
Post-ARD Additional Interest Distribution Account, Interest Reserve Account and
Excess Liquidation Proceeds Account prior to any change thereof.

            (f) (i) If any A/B Material Default occurs and is continuing with

      Pair;

            (viii) insofar as they do not constitute Escrow Payments or Reserve
      Funds, any amounts paid by a Borrower specifically to cover items for
      which a Servicing Advance has been made or that represent a recovery of
      property protection expenses from a Borrower relating to such A/B Loan
      Pair;

            (ix) any amounts received pursuant to Section 3.18 that relate to

      Custodial Account.

            The foregoing requirements for deposit by the applicable Master
Servicer in an A/B Loan Pair Custodial Account shall be exclusive, it being
understood and agreed that actual payments from a Borrower in the nature of
Escrow Payments, charges for beneficiary statements or demands, assumption fees,
modification fees, extension fees, amounts collected for Borrower checks
returned for insufficient funds or other amounts that the Master Servicer or the
Special Servicer is entitled to retain as additional servicing compensation
pursuant to Section 3.11 need not be deposited by the applicable Master Servicer
in such A/B Loan Pair Custodial Account. If the applicable Master Servicer shall
deposit in any A/B Loan Pair Custodial Account any amount not required to be

Pair Custodial Account, notwithstanding any provision in this Agreement to the
contrary.

            Within one Business Day of receipt of any of the amounts described

shall remit such amounts to the applicable Master Servicer for deposit in the
related A/B Loan Pair Custodial Account pursuant to the second preceding
paragraph. Any amounts received by the applicable Special Servicer with respect

            If any B Loan that relates to a CBA A/B Loan Pair is being serviced
hereunder and with respect to the 622 Third Avenue Loan and the Washington
Center Loan, or if the Mortgaged Property securing any CBA A/B Loan Pair has
become REO Property, then as and when required pursuant to the related A/B
Intercreditor Agreement (and in any event on the Business Day following each
Determination Date), the applicable Master Servicer shall withdraw from the
related A/B Loan Pair Custodial Account and pay to the applicable parties
hereunder such amounts as is permitted under the related A/B Intercreditor
Agreement for purposes of the reimbursement of Advances, the payment of interest
on Advances, the payment of Servicing Fees, Special Servicing Fees, Workout Fees
and Liquidation Fees and the payment of any other servicing expenses and fees
relating to the subject A/B Loan Pair or any related REO Property and, further,
pay to the Trust, as "A Note Holder" under the related A/B Intercreditor
Agreement, and to the B Loan Holder or the Washington Center Junior Holders, as
applicable, all amounts to which each of them is entitled in respect of the
subject A Loan, B Loan and C Loan, respectively, in accordance with the related
A/B Intercreditor Agreement. The foregoing payments shall be made in accordance
with the priorities set forth in the related A/B Intercreditor Agreement.
Payments to the Trust shall be made by transfer of the applicable funds to the
Collection Account, and payments to the B Loan Holder or the Washington Center
Junior Holders, as applicable, shall be made in accordance with the related A/B
Intercreditor Agreement.

            (g) Notwithstanding the foregoing or any other provision to the
contrary in this Agreement, the Trustee may maintain the Distribution Account,
the Interest Reserve Account and the Excess Liquidation Proceeds Account as
three separate subaccounts of a single Eligible Account; provided that: (i) all
deposits into and withdrawals from such single Eligible Account shall be made in
the same manner as would be the case if the Distribution Account, the Interest
Reserve Account and the Excess Liquidation Proceeds Account were maintained as
three separate accounts; (ii) all distributions on the Certificates shall be
calculated and made in the same manner as would be the case if the Distribution
Account, the Interest Reserve Account and the Excess Liquidation Proceeds
Account were maintained as three separate accounts; (iii) the Trustee shall make
debits and credits to those three subaccounts in a manner consistent with the
provisions of this Agreement governing transfers of funds between the
Distribution Account, the Interest Reserve Account and the Excess Liquidation
Proceeds Account, as the case may be; (iv) the Trustee's maintaining the
Distribution Account, the Interest Reserve Account and the Excess Liquidation
Proceeds Account as three separate subaccounts of a single Eligible Account (as
opposed to in the form of three separate Eligible Accounts) shall not materially
and adversely affect any of the Certificateholders; and (v) such single Eligible
Account shall be entitled "Wells Fargo Bank Minnesota, N.A., as Trustee, in
trust for the registered holders of Credit Suisse First Boston Mortgage
Securities Corp., Commercial Mortgage Pass-Through Certificates, Series 2003-C3,
Distribution Account, Interest Reserve Account and Excess Liquidation Proceeds
Account".

      Section 3.26, out of Default Charges collected on the Mortgage Loan or REO
      Mortgage Loan, as the case may be, as to which the related Advance was
      made;

            (viii) to the extent that, during any Collection Period, such Master

      Servicer, the Trustee or any Fiscal Agent, as applicable, for any
      unreimbursed Advance with respect to any Mortgage Loan or REO Property as
      to which such Master Servicer is the applicable Master Servicer
      (regardless of whether such reimbursement is pursuant to clause (ii), (v)
      or (vi) above or pursuant to Section 3.03(c) or Section 3.03(d)), and
      insofar as payment has not already been made out of related Default

      likely otherwise become Additional Trust Fund Expenses, such payment to be
      made, as and to the extent contemplated by Section 3.26, out of Default
      Charges collected on the related Mortgage Loan or REO Mortgage Loan, as
      the case may be, and then from Liquidation Proceeds from the related

      then on deposit in such Collection Account, certain servicing expenses
      related to the Mortgage Loans and REO Properties as to which such Master
      Servicer is the applicable Master Servicer, which expenses would, if
      advanced, constitute Nonrecoverable Servicing Advances;

            (xiii) to pay, first out of related Liquidation Proceeds, and then,
      out of such general collections on the Mortgage Loans and any REO
      Properties as are then on deposit in such Collection Account, costs and

      specifically required to be paid to such Person at the expense of the
      Trust Fund under any provision of this Agreement and to which reference is
      not made in any other clause of this Section 3.05(a), it being
      acknowledged that this clause (xvii) shall not be construed to modify any
      limitation otherwise set forth in this Agreement on the time at which any
      Person is entitled to payment or reimbursement of any amount or the funds
      from which any such payment or reimbursement is permitted to be made;

            (xviii) to pay itself, either Special Servicer, any Mortgage Loan

funds remaining on deposit in such Collection Account on a pro rata basis with
any and all other payments, reimbursements or remittances to be made from such
general funds; provided that amounts payable pursuant to clauses (vi) through
(viii) shall be paid, pro rata, prior to any other such payments, reimbursements
or remittances; and provided, further, that amounts payable pursuant to clause
(xiv) shall be paid after the amounts specified in the preceding proviso but
prior to any other such payments, reimbursements or remittances; and provided,
further, that any reimbursements of Advances in respect of any particular
Mortgage Loan or REO Property out of a Collection Account pursuant to any of
clauses (ii), (v) and (vi) above, and any payments of interest thereon out of a
Collection Account pursuant to either of clauses (vii) and (viii) above, shall
be made (to the extent of their respective entitlements to such reimbursements
and/or payments): first, to any Fiscal Agent; second, to the Trustee; and third,
pro rata, to the applicable Master Servicer and Special Servicer; provided, that
nothing in this paragraph shall affect the timing of payments to any B Loan
Holder or Washington Center Junior Holder of any amounts held in the A/B Loan
Custodial Account pursuant to Section 3.05(f) or amounts due to any B Loan
Holder or Washington Center Junior Holder pursuant to clause (xix) above or any
other relevant Section herein.

            No party hereto shall be entitled to payment or reimbursement of any
amount from general collections on deposit in the Collection Account with
respect to any A Loan or related REO Property for which it can be reimbursed out
of amounts then on deposit in the related A/B Loan Pair Custodial Account and,
in the case of the B Loans or the Washington Center Junior Loans, as the case
may be:

            (A) the applicable Master Servicer shall be entitled to make
transfers from time to time, from the related A/B Loan Pair Custodial Account to
the portion of its Collection Account that does not constitute the A/B Loan Pair
Custodial Account, of amounts necessary for the payments or reimbursement of
amounts described in any one or more of clauses (ii), (iii), (iv), (v), (vi),
(vii), (viii), (x) and (xiii) above, but only insofar as the payment or
reimbursement described therein arises from or is related solely to an A Loan
pursuant to this Agreement and has been allocated to the related B Loan or the
Washington Center Junior Loans pursuant to the related A/B Intercreditor
Agreement, and the applicable Master Servicer shall also be entitled to make
transfers from time to time, from the related A/B Loan Pair Custodial Account to
the portion of its Collection Account that does not constitute the A/B Loan Pair
Custodial Account, of amounts transferred to such related A/B Loan Pair
Custodial Account in error, and amounts necessary for the clearing and
termination of its Collection Account pursuant to Section 9.01;

            (B) the applicable Master Servicer shall be entitled to make
transfers from time to time, from the related A/B Loan Pair Custodial Account to
the portion of its Collection Account that does not constitute the A/B Loan Pair
Custodial Account, of amounts not otherwise described in clause (A) above to
which the holder of an A Note is entitled under the related A/B Intercreditor
Agreement (including in respect of interest, principal and Prepayment Premiums
due in respect of the A Note (whether or not by operation of any provision of
the related A/B Intercreditor Agreement that entitles the holder of such A Note
to receive remittances in amounts calculated without regard to any modification,
waiver or amendment of the economic terms of such A Note));

            (C) the applicable Master Servicer shall on the Business Day
following receipt of payment from the related Borrower, remit to the B Loan
Holder and the Washington Center Junior Holders any amounts on deposit in such
A/B Loan Pair Custodial Account (net of amounts permitted or required to be
transferred therefrom as described in clauses (A) and/or (B) above), to the
extent that the B Loan Holder and the Washington Center Junior Holders are
entitled thereto under the related A/B Intercreditor Agreement (including by way
of the operation of any provision of the related A/B Intercreditor Agreement
that entitles the B Loan Holder and the Washington Center Junior Holders to
reimbursement of cure payments made by it).

            Expenses incurred with respect to any B Loan or the Washington
Center Junior Loans shall be allocated in accordance with the related A/B
Intercreditor Agreement. The applicable Master Servicer shall keep and maintain
a separate accounting for each Mortgage Loan, B Loan and Washington Center
Junior Loans for the purpose of justifying any withdrawal or transfer from its
Collection Account and any A/B Loan Pair Custodial Account. The applicable
Master Servicer shall not be permitted to withdraw any funds from the portion of
its Collection Account that does not constitute the A/B Loan Pair Custodial
Account unless there are no remaining funds in the related A/B Loan Pair
Custodial Account available and amounts are required to be paid in accordance
with the related A/B Intercreditor Agreement. If the applicable Master Servicer
is entitled to make any payment or reimbursement described above and such
payment or reimbursement relates to a B Loan or the Washington Center Junior
Loans but is not limited to a specific source of funds (other than the
requirement that it must be made by withdrawal from the A/B Loan Pair Custodial
Account insofar as it relates to a B Loan or any Washington Center Junior Loan
and is permitted pursuant to the related A/B Intercreditor Agreement), the
applicable Master Servicer shall, if funds on deposit in such A/B Loan Pair
Custodial Account are insufficient therefor, request the B Loan Holder or the
Washington Center Junior Holders to make such payment or reimbursement to the
extent the B Loan Holder or the Washington Center Junior Holders are obligated
to make such payment or reimbursement pursuant to the related A/B Intercreditor
Agreement. If the B Loan Holder or any Washington Center Junior Holder fails to
make such payment or reimbursement that it is obligated to make and the
applicable Master Servicer deems the payment or reimbursement necessary to
protect the related Mortgaged Property from a default, delinquency or other
anticipated event that is imminent with respect to the related Mortgage Loan in
its reasonable judgment and in accordance with the Servicing Standard, the
applicable Master Servicer shall be entitled to make such payment or
reimbursement from its Collection Account. If such payment or reimbursement is
subsequently recovered from the B Loan Holder or any Washington Center Junior
Holder (including, if permitted by the related A/B Intercreditor Agreement, by
offsetting against subsequent amounts payable to the B Loan Holder or the
Washington Center Junior Holders), to the extent that any amounts were
previously taken by the applicable Master Servicer from its Collection Account,
the amount recovered shall be deposited into its Collection Account and shall
not be deposited into the A/B Loan Pair Custodial Account.

            Each Master Servicer shall pay to the applicable Special Servicer
from such Master Servicer's Collection Account on each Master Servicer
Remittance Date amounts permitted to be paid to such Special Servicer therefrom
based upon an Officer's Certificate received from such Special Servicer on the
first Business Day following the immediately preceding Determination Date,
describing the item and amount to which such Special Servicer is entitled. Each
Master Servicer may rely conclusively on any such certificate and shall have no
duty to re-calculate the amounts stated therein. Each Special Servicer shall
keep and maintain separate accounting for each Specially Serviced Mortgage Loan
and REO Property as to which it is the applicable Special Servicer, on a
loan-by-loan and property-by-property basis, for the purpose of justifying any
request thereby for withdrawal from a Collection Account.

            (b) The Trustee shall, from time to time, make withdrawals from the
Lower-Tier Distribution Account or the 622 Third Avenue Loan REMIC Distribution
Account, as applicable, for each of the following purposes (the order set forth
below not constituting an order of priority for such withdrawals):

            (i) to make distributions or deemed distributions from the 622 Third
      Avenue Loan REMIC to the Lower-Tier Distribution Account in respect of the
      622 Third Avenue Loan REMIC Regular Interests pursuant to Section 4.01(a),
      Section 4.01(c) and Section 4.01(d) and distributions of the Lower-Tier
      Distribution Amount pursuant to Section 4.01(c) and the amount of any
      Prepayment Premium and Yield Maintenance Charges distributable pursuant to
      Section 4.01(d) from the Lower-Tier Distribution Account to the Upper-Tier
      Distribution Account;

            (ii) to transfer Interest Reserve Amounts in respect of the Interest
      Reserve Mortgage Loans to the Interest Reserve Account as and when
      required by Section 3.04(c);

            (iii) to pay itself, either Master Servicer, either Special
      Servicer, the Depositor, the Trustee, any Fiscal Agent or any of their
      respective directors, officers, members, managers, employees and agents,
      as the case may be, any amounts payable to any such Person pursuant to
      Section 6.03, Section 7.01(b), Section 8.05 or Section 8.13, as
      applicable, if and to the extent such amounts are not payable out of a
      Collection Account pursuant to Section 3.05;

            (iv) to pay for the cost of the Opinions of Counsel sought by the
      Trustee as contemplated by Section 11.01(a) or Section 11.01(c) in
      connection with any amendment to this Agreement requested by the Trustee
      which amendment is in furtherance of the rights and interests of
      Certificateholders;

            (v) to pay any and all federal, state and local taxes imposed on the
      Upper-Tier REMIC, the Lower-Tier REMIC or the 622 Third Avenue Loan REMIC
      created hereunder, together with all incidental costs and expenses, and
      any and all expenses relating to tax audits, if and to the extent that
      either (A) none of the parties hereto are liable therefor pursuant to
      Section 10.01(b) and/or Section 10.01(f) or (B) any such Person that may
      be so liable has failed to timely make the required payment; and

            (vi) to clear and terminate the 622 Third Avenue Loan REMIC
      Distribution Account and the Lower-Tier Distribution Account at the
      termination of this Agreement pursuant to Section 9.01.

            (c) On the Master Servicer Remittance Date in March of each year
(commencing in March 2004), and in any event on the Master Servicer Remittance
Date that occurs in the same calendar month as the Final Distribution Date, the
Trustee shall withdraw from the Interest Reserve Account and deposit in the 622
Third Avenue Loan REMIC Distribution Account and the Lower-Tier Distribution
Account, as applicable, all Interest Reserve Amounts in respect of the Interest
Reserve Mortgage Loans then on deposit in the Interest Reserve Account. In
addition, the Trustee shall, from time to time, make withdrawals from the
Interest Reserve Account to pay itself interest or other income earned on
deposits in the Interest Reserve Account, in accordance with Section 3.06(b)
(but only to the extent of the Net Investment Earnings, if any, with respect to
the Interest Reserve Account for each Collection Period).

            (d) On the Business Day prior to each Distribution Date, the Trustee
shall withdraw from the Excess Liquidation Proceeds Account and deposit in the
Distribution Account, for distribution on such Distribution Date, an amount
equal to the lesser of (i) the entire amount, if any, then on deposit in the
Excess Liquidation Proceeds Account and (ii) the excess, if any, of the
aggregate amount distributable on such Distribution Date pursuant to Sections
4.01(a) and 4.01(b), over the Standard Available Distribution Amount for such
Distribution Date (calculated without regard to such transfer from the Excess
Liquidation Proceeds Account to the Distribution Account); provided that on the
Business Day prior to the Final Distribution Date, the Trustee shall withdraw
from the Excess Liquidation Proceeds Account and deposit in the Lower-Tier
Distribution Account, for distribution on such Distribution Date, any and all
amounts then on deposit in the Excess Liquidation Proceeds Account. In addition,
the Trustee shall, from time to time, make withdrawals from the Excess
Liquidation Proceeds Account to pay itself interest or other income earned on
deposits in the Excess Liquidation Proceeds Account, in accordance with Section
3.06(b) (but only to the extent of the Net Investment Earnings, if any, with
respect to the Excess Liquidation Proceeds Account for each Collection Period).

            (e) The Trustee, any Fiscal Agent, the Depositor, the Master
Servicers and the Special Servicers, as applicable, shall in all cases have a
right prior to the Certificateholders to any particular funds on deposit in
Collection Account and the Distribution Account from time to time for the
reimbursement or payment of compensation, Advances (with interest thereon at the
Reimbursement Rate) and their respective expenses hereunder, but only if and to
the extent such compensation, Advances (with interest) and expenses are to be
reimbursed or paid from such particular funds on deposit in such Collection
Account or the Distribution Account pursuant to the express terms of this
Agreement.

            Section 3.06 Investment of Funds in the Accounts

            (a) Each Master Servicer may direct (pursuant to a standing order or
otherwise) any depository institution (including the Trustee) maintaining a
Collection Account, any A/B Loan Pair Custodial Account or any Servicing Account
or Reserve Account held by it, and each Special Servicer may direct (pursuant to
a standing order or otherwise) any depository institution (including the
Trustee) maintaining an REO Account, and the Trustee may direct (pursuant to a
standing order or otherwise) any depository institution maintaining the
Distribution Account, the Interest Reserve Account or the Excess Liquidation
Proceeds Account (each such account, for purposes of this Section 3.06, an
"Investment Account"), to invest, or if any of the Master Servicers, the Special
Servicers or the Trustee is such depository institution, such Master Servicer,
such Special Servicer or the Trustee may invest itself, the funds held therein
in (but only in) one or more Permitted Investments bearing interest or sold at a
discount, and maturing, unless payable on demand, no later than the Business Day
immediately preceding the next succeeding date on which such funds are required
to be withdrawn from such account pursuant to this Agreement or the related
Mortgage Loan Documents, as applicable, or with respect to Permitted Investments
of funds held in the Distribution Account, no later than 12:00 p.m. on the next
succeeding Distribution Date; provided that any such investment of funds in any
Servicing Account or Reserve Account shall be subject to applicable law and the
terms of the related Mortgage Loan Documents; and provided, further, that the
funds in any Investment Account shall remain uninvested unless and until the
applicable Master Servicer, the applicable Special Servicer or the Trustee, as
applicable, gives timely investment instructions with respect thereto pursuant
to this Section 3.06. 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). Each Master
Servicer (with respect to Permitted Investments of amounts in its Collection
Account, any A/B Custodial Account or any Servicing Account or Reserve Account
maintained by it) and each Special Servicer (with respect to Permitted
Investments of amounts in its REO Account), acting on behalf of the Trustee,
shall (and Trustee hereby designates the applicable Master Servicer or Special
Servicer, as the case may be, as the Person that shall), and the Trustee (with
respect to Permitted Investments of amounts in the Distribution Account, the
Interest Reserve Account or the Excess Liquidation Proceeds Account), acting on
behalf of itself, shall (i) be the "entitlement holder" of any Permitted
Investment that is a "security entitlement" and (ii) maintain "control" of any
Permitted Investment that is either a "certificated security" or an
"uncertificated security". For purposes of this Section 3.06(a), the terms "
entitlement holder", "security entitlement", "control", "certificated security"
and "uncertificated security" shall have the meanings given such terms in
Revised Article 8 (1994 Revision) of the UCC, and "control" of any Permitted
Investment by a Master Servicer, a Special Servicer or the Trustee shall
constitute "control" by a Person designated by, and acting on behalf of, the
Trustee for purposes of Revised Article 8 (1994 Revision) of the UCC. If amounts
on deposit in an Investment Account are at any time invested in a Permitted
Investment payable on demand, the party hereunder that maintains such account
(whether it is a Master Servicer, a Special Servicer or Trustee), shall:

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

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

            (b) Whether or not a Master Servicer directs the investment of funds
in its Collection Account, or any A/B Loan Pair Custodial Account, interest and
investment income realized on funds deposited therein, to the extent of the Net
Investment Earnings, if any, for such Investment Account for each Collection
Period, shall be for the sole and exclusive benefit of such Master Servicer and
shall be subject to its withdrawal in accordance with Section 3.05(a). Whether
or not a Master Servicer directs the investment of funds in any Servicing
Account or Reserve Account maintained by it, interest and investment income
realized on funds deposited therein, to the extent of the Net Investment
Earnings, if any, for such Investment Account for each Collection Period, and
subject to the requirements of applicable law or the terms of the related
Mortgage Loan regarding the payment of such interest and investment income to
the related Borrower, shall be for the sole and exclusive benefit of such Master
Servicer and shall be subject to withdrawal from time to time in accordance with
Section 3.03. Whether or not a Special Servicer directs the investment of funds
in an REO Account, interest and investment income realized on funds deposited
therein, to the extent of any Net Investment Earnings, if any, for such
Investment Account for each Collection Period, shall be for the sole and
exclusive benefit of such Special Servicer and shall be subject to its
withdrawal in accordance with Section 3.16(b). Whether or not the Trustee
directs the investment of funds in the Distribution Account, the Interest
Reserve Account or the Excess Liquidation Proceeds Account, interest and
investment income realized on funds deposited therein, to the extent of the Net
Investment Earnings, if any, for such Account for each Collection Period, shall
be for the sole and exclusive benefit of the Trustee and shall be subject to its
withdrawal in accordance with Section 3.05(b). If any loss shall be incurred in
respect of any Permitted Investment on deposit in any Investment Account (other
than a loss of what would otherwise have constituted investment earnings), the
applicable Master Servicer (in the case of a Collection Account and any
Servicing Account or Reserve Account), the applicable Special Servicer (in the
case of an REO Account) and the Trustee (in the case of the Distribution
Account, the Interest Reserve Account or the Excess Liquidation Proceeds
Account) shall promptly deposit therein (or, solely to the extent that the loss
is of an amount credited to an A/B Loan Pair Custodial Account, deposit to the
related A/B Loan Pair Custodial Account, as the case may be) from its own funds,
without right of reimbursement, no later than the end of the Collection Period
during which such loss was incurred, the amount of the Net Investment Loss, if
any, in respect of such Investment Account for such Collection Period (or, in
the case of a Servicing Account or Reserve Account, the entire amount of such
loss), except (in the case of any such loss with respect to a Servicing Account
or Reserve Account) to the extent the loss amounts were invested for the benefit
of a Borrower under the terms of a Mortgage Loan or applicable law and such
Borrower has no recourse against the Trust in respect of such loss.

            (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of any payment due (or in any other performance
required) under any Permitted Investment of funds on deposit in any Account
(exclusive of the Distribution Account, the Interest Reserve Account and the
Excess Liquidation Proceeds Account), and if the Master Servicer or Special
Servicer, as the case may be, that maintains such Account, is in default of its
obligations under or contemplated by Section 3.06(b), the Trustee may (and,
subject to Section 8.02, upon the request of (i) Holders of Certificates
entitled to not less than 25% of the Voting Rights allocated to any Class of
Regular Certificates or (ii) the Controlling Class Representative, the Trustee
shall) take such action as may be appropriate to enforce such payment or
performance, including the institution and prosecution of appropriate legal
proceedings. Any costs incurred by the Trustee in taking any such action shall
be reimbursed to it by the Master Servicer or Special Servicer, as the case may
be, that maintains such Account. This provision is in no way intended to limit
any actions that a Master Servicer or Special Servicer may take in this regard
at its own expense.

            (d) Notwithstanding the investment of funds held in any Investment
Account, for purposes of the calculations hereunder, including the calculation
of the Standard Available Distribution Amount and the Master Servicer Remittance
Amount, the amounts so invested shall be deemed to remain on deposit in such
Investment Account.

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

            (a) Each Master Servicer shall use reasonable efforts consistent
with the Servicing Standard to cause each Borrower with respect to the Mortgage
Loans for which it acts as Master Servicer to maintain, and, if the Borrower
does not so maintain, such Master Servicer will itself cause to be maintained,
for each Mortgaged Property (including each Mortgaged Property relating to any
Specially Serviced Mortgage Loan) all insurance coverage as is required, subject
to applicable law, under the related Mortgage Loan Documents; provided that, if
and to the extent that any such Mortgage permits the holder thereof any
discretion (by way of consent, approval or otherwise) as to the insurance
coverage that the related Borrower is required to maintain, such Master Servicer
shall exercise such discretion in a manner consistent with the Servicing
Standard, with a view towards requiring insurance comparable to that required
under other Mortgage Loans with express provisions governing such matters and,
in any event, business interruption or rental loss insurance for at least 12
months; and provided, further, that, if and to the extent that any such Mortgage
so permits, the related Borrower shall be required to obtain the required
insurance coverage from Qualified Insurers that, in each case, have a financial
strength or claims-paying rating no lower than two rating categories below the
highest rated Certificates outstanding, and in any event no lower than "A-" from
S&P and Fitch and "A3" from Moody's (or in such other form and amount or issued
by an insurer with such other financial strength or claims-paying ability as
would not, as confirmed in writing by the relevant Rating Agency, result in an
Adverse Rating Event); and provided, further, that such Master Servicer shall be
required to maintain such insurance coverage upon the related Borrower's failure
to do so only to the extent that (i) the Trustee as mortgagee has an insurable
interest, (ii) such insurance is available at commercially reasonable rates (as
determined by the applicable Master Servicer and approved by the Controlling
Class Representative, which approval shall be deemed given if not disapproved in
writing within 10 Business Days) and (iii) any related Servicing Advance is
deemed by the applicable Master Servicer to be recoverable from collections on
the related Mortgage Loan; provided, that if such Servicing Advance is deemed a
Nonrecoverable Servicing Advance the applicable Master Servicer may (or, at the
direction of the applicable Special Servicer if a Specially Serviced Mortgage
Loan or an REO Property is involved shall) pay such amounts out of the
applicable Collection Account provided, further, that the applicable Master
Servicer (or the applicable Special Servicer, if a Specially Serviced Mortgage
Loan or an REO Property is involved) has determined in accordance with the
Servicing Standard that making such payment is in the best interests of the
Certificateholders and any related B Loan Holder and Washington Center Junior
Holder (as a collective whole), as evidenced in each case by any Officer's
Certificate delivered promptly to the Trustee, the Depositor and the Controlling
Class Representative, setting forth the basis for such determination and
accompanied by any information that such Person may have obtained that supports
such determination. Subject to Section 3.17(b), each Special Servicer shall also
cause to be maintained for each REO Property with respect to the Mortgage Loans
for which it acts as Special Servicer no less insurance coverage, the cost of
which shall be paid by the applicable Master Servicer as a Servicing Advance (to
the extent available at commercially reasonable rates as determined by the
Controlling Class Representative) than was previously required of the Borrower
under the related Mortgage and, at a minimum, (i) hazard insurance with a
replacement cost rider, (ii) business interruption or rental loss insurance for
at least 12 months, and (iii) commercial general liability insurance, in each
case, in an amount customary for the type and geographic location of such REO
Property and consistent with the Servicing Standard; provided that all such
insurance shall be obtained from Qualified Insurers that, in each case, shall
have a financial strength or claims-paying rating no lower than two rating
categories below the highest rated Certificates outstanding, and in any event no
lower than "A-" from S&P and Fitch and "A3" from Moody's (or in such other form
and amount or issued by an insurer with such other financial strength or
claims-paying ability as would not, as confirmed in writing by the relevant
Rating Agency, result in an Adverse Rating Event). All such insurance policies
shall contain (if they insure against loss to property) a "standard" mortgagee
clause, with loss payable to the applicable Master Servicer on behalf of the
Trustee (on behalf of the Certificateholders and, if related to the 622 Third
Avenue Loan or the Washington Center Loan, the 622 Third Avenue B Loan Holder
and each Washington Center Junior Holder, respectively) (in the case of
insurance maintained in respect of Mortgage Loans), or shall name the Trustee as
the insured, with loss payable to the applicable Special Servicer on behalf of
the Trustee (on behalf of the Certificateholders and, if related to the 622
Third Avenue Loan or the Washington Center Loan, the 622 Third Avenue B Loan
Holder and each Washington Center Junior Holder, respectively) (in the case of
insurance maintained in respect of REO Properties), and shall be issued by an
insurer authorized under applicable law to issue such insurance. Any amounts
collected by a Master Servicer or a Special Servicer under any such policies
(other than amounts to be applied to the restoration or repair of the related
Mortgaged Property or REO Property or amounts to be released to the related
Borrower, in each case in accordance with the Servicing Standard) shall be
deposited in the Collection Account or any related A/B Loan Pair Custodial
Account, subject to withdrawal pursuant to Section 3.05(a), in the case of
amounts received in respect of a Mortgage Loan, or in the REO Account, subject
to withdrawal pursuant to Section 3.16(c), in the case of amounts received in
respect of an REO Property. Any cost incurred by a Master Servicer or a Special
Servicer in maintaining any such insurance shall not, for purposes hereof,
including calculating monthly distributions to Certificateholders, be added to
unpaid principal balance or Stated Principal Balance of the related Mortgage
Loan, notwithstanding that the terms of such Mortgage Loan so permit; provided,
however, that this sentence shall not limit the rights of the applicable Master
Servicer on behalf of the Trust to enforce any obligations of the related
Borrower under such Mortgage Loan. Costs to a Master Servicer or a Special
Servicer of maintaining insurance policies pursuant to this Section 3.07 shall
be paid by and reimbursable to the applicable Master Servicer as a Servicing
Advance.

            Subject to the preceding paragraph, the applicable Master Servicer
shall use reasonable efforts to cause the Borrower to maintain or, if the
Borrower does not so maintain, the applicable Master Servicer will maintain
all-risk casualty insurance or extended coverage insurance (with special form
coverage) (the cost of which shall be payable as a Servicing Advance), which
does not contain any exclusion for terrorist or similar acts; provided, however,
the applicable Master Servicer shall not require any Borrower to obtain or
maintain insurance in excess of the amounts of coverage and deductibles required
by the related Mortgage Loan Documents or the related Mortgage Loan Seller in
connection with the origination of a Mortgage Loan unless such Master Servicer
determines, in accordance with the Servicing Standard, that such insurance
required at origination would not be prudent for a Mortgaged Property of the
same type as the related Mortgaged Property. The applicable Master Servicer
shall not be required to call a default under a Mortgage Loan if the related
Borrower fails to maintain such insurance, and the applicable Master Servicer
shall not be required to maintain such insurance, to the extent, if any, that
the cost of such insurance exceeds the maximum cost that the related Borrower is
required to incur under the related Mortgage Loan Documents, or if the
applicable Master Servicer has determined in accordance with the Servicing
Standard that either (i) such insurance is not available at commercially
reasonable rates or that such hazards are not at the time commonly insured
against for properties similar to the Mortgaged Property and located in or
around the region in which such Mortgaged Property is located (which
determination shall be subject to the approval of the Controlling Class
Representative, which approval shall be deemed given if not disapproved in
writing within 10 Business Days), or (ii) such insurance is not available at any
rate.

            (b) If a Master Servicer or Special Servicer shall obtain and
maintain, or cause to be obtained and maintained, a blanket policy or master
force placed policy insuring against hazard losses on all of the Mortgage Loans
or REO Properties, as applicable, as to which it is the applicable Master
Servicer or Special Servicer, as the case may be, then, to the extent such
policy (i) is obtained from a Qualified Insurer having a financial strength or
claims-paying rating no lower than "A" from S&P and Fitch and "A2" from Moody's
or having such other financial strength or claims-paying ability rating as would
not, as confirmed in writing by the relevant Rating Agency, result in an Adverse
Rating Event, and (ii) provides protection equivalent to the individual policies
otherwise required, such Master Servicer or Special Servicer, as the case may
be, shall conclusively be deemed to have satisfied its obligation to cause
hazard insurance to be maintained on the related Mortgaged Properties or REO
Properties, as applicable. Such a blanket or master force placed policy may
contain a deductible clause (not in excess of a customary amount), in which case
the applicable Master Servicer or the applicable Special Servicer, as the case
may be, that maintains such policy shall, if there shall not have been
maintained on any Mortgaged Property (other than the Great Lakes Crossing
Mortgaged Property) or REO Property thereunder a hazard insurance policy
complying with the requirements of Section 3.07(a), and there shall have been
one or more losses that would have been covered by such an individual policy,
promptly deposit into the Collection Account or A/B Loan Pair Custodial Account,
as applicable, maintained by the applicable Master Servicer, from its own funds,
the amount not otherwise payable under the blanket or master force placed policy
in connection with such loss or losses because of such deductible clause to the
extent that any such deductible exceeds the deductible limitation that pertained
to the related Mortgage Loan (or, in the absence of any such deductible
limitation, the deductible limitation for an individual policy which is
consistent with the Servicing Standard). The applicable Master Servicer or the
applicable Special Servicer, as appropriate, shall prepare and present, on
behalf of itself, the Trustee and Certificateholders, claims under any such
blanket or master force placed policy in a timely fashion in accordance with the
terms of such policy.

            (c) Within 45 days after the Closing Date, with respect to each of
the Mortgage Loans for which it acts as Master Servicer covered by an
Environmental Insurance Policy that are listed on Exhibit B-4 to this Agreement,
each Master Servicer shall notify the insurer under such Environmental Insurance
Policy and take all other action necessary for the Trustee, on behalf of the
Certificateholders and, with respect to the Washington Center Loan, for the
nenefit of the Washington Center Junior Holders and the Certificateholders, as a
collective whole, to be an insured (and for such Master Servicer, on behalf of
the Trust, to make claims) under such Environmental Insurance Policy. In the
event that a Master Servicer has actual knowledge of any event (an "Insured
Environmental Event") giving rise to a claim under any Environmental Insurance
Policy in respect of any Mortgage Loan covered thereby, such Master Servicer
shall, in accordance with the terms of such Environmental Insurance Policy and
the Servicing Standard, timely make a claim thereunder with the appropriate
insurer and shall take such other actions in accordance with the Servicing
Standard which are necessary under such Environmental Insurance Policy in order
to realize the full value thereof for the benefit of the Certificateholders and,
with respect to the Washington Center Loan, for the benefit of the Washington
Center Junior Holders and the Certificateholders, as a collective whole. If any
other party hereto has actual knowledge of an Insured Environmental Event with
respect to any Mortgage Loan listed on Exhibit B-4 to this Agreement, such party
shall promptly so notify the applicable Master Servicer. Any legal fees,
premiums or other out-of-pocket costs incurred in accordance with the Servicing
Standard in connection with any such claim under an Environmental Insurance
Policy shall be paid by the applicable Master Servicer and shall be reimbursable
to it as a Servicing Advance. With respect to each Environmental Insurance
Policy that relates to one or more Mortgage Loans, serviced by a Master
Servicer, such Master Servicer shall review and familiarize itself with the
terms and conditions relating to enforcement of claims and shall monitor the
dates by which any claim must be made or any action must be taken under such
policy to realize the full value thereof for the benefit of the
Certificateholders and, with respect to the Washington Center Loan, for the
benefit of the Washington Center Junior Holders and the Certificateholders, as a
collective whole. in the event such Master Servicer has actual knowledge of an
Insured Environmental Event giving rise to a claim under such policy.

            In the event that a Master Servicer receives notice of any
termination of any Environmental Insurance Policy that relates to one or more
Mortgage Loans, for which it acts as Master Servicer, such Master Servicer
shall, within five Business Days after receipt of such notice, notify the
applicable Special Servicer, the Controlling Class Representative, the Rating
Agencies and the Trustee of such termination in writing. Upon receipt of such
notice, such Master Servicer shall address such termination in accordance with
Section 3.07(a) in the same manner as it would the termination of any other
Insurance Policy required under the related Mortgage Loan Documents. Any legal
fees, premiums or other out-of-pocket costs incurred in accordance with the
Servicing Standard in connection with a resolution of such termination of an
Environmental Insurance Policy shall be paid by the applicable Master Servicer
and shall be reimbursable to it as a Servicing Advance.

            (d) Each Master Servicer and each Special Servicer shall at all
times during the term of this Agreement (or, in the case of a Special Servicer,
at all times during the term of this Agreement during which Specially Serviced
Mortgage Loans and/or REO Properties as to which it is the applicable Special
Servicer exist as part of the Trust Fund) keep in force with a Qualified Insurer
having a financial strength or claims-paying rating no lower than two rating
categories below the highest rated Certificates outstanding, and in any event no
lower than "A" from S&P and Fitch, a fidelity bond in such form and amount as
would permit it to be a qualified Fannie Mae seller-servicer of multifamily
mortgage loans (or in such other form and amount or issued by an insurer with
such other financial strength or claims-paying ability rating as would not
result in an Adverse Rating Event with respect to any Class of Rated
Certificates (as confirmed in writing to the Trustee by the relevant Rating
Agency)). Each Master Servicer and each Special Servicer shall be deemed to have
complied with the foregoing provision if an Affiliate thereof has such fidelity
bond coverage and, by the terms of such fidelity bond, the coverage afforded
thereunder extends to the applicable Master Servicer or the applicable Special
Servicer, as the case may be. Such fidelity bond shall provide that it may not
be canceled without ten days' prior written notice to the Trustee.

            Each Master Servicer and each Special Servicer shall at all times
during the term of this Agreement (or, in the case of a Special Servicer, at all
times during the term of this Agreement during which Specially Serviced Mortgage
Loans and/or REO Properties as to which it is the applicable Special Servicer
exist as part of the Trust Fund) also keep in force with a Qualified Insurer
having a financial strength or claims-paying rating no lower than two rating
categories below the highest rated Certificates outstanding, and in any event no
lower than "A" from S&P and Fitch, a policy or policies of insurance covering
loss occasioned by the errors and omissions of its officers and employees in
connection with its servicing obligations hereunder and, to the limited extent
contemplated by Articles I through XI, to administer the Great Lakes Crossing
Mortgage Loan, which policy or policies shall be in such form and amount as
would permit it to be a qualified Fannie Mae seller-servicer of multifamily
mortgage loans (or in such other form and amount or issued by an insurer with
such other financial strength or claims-paying rating as would not result in an
Adverse Rating Event with respect to any Class of Rated Certificates (as
confirmed in writing to the Trustee by the relevant Rating Agency)). Each Master
Servicer and each Special Servicer shall be deemed to have complied with the
foregoing provisions if an Affiliate thereof has such insurance and, by the
terms of such policy or policies, the coverage afforded thereunder extends to
the applicable Master Servicer or the applicable Special Servicer, as the case
may be. Any such errors and omissions policy shall provide that it may not be
canceled without ten days' prior written notice to the Trustee.

            Section 3.08 Enforcement of Alienation Clauses

            Each Master Servicer (with respect to Performing Mortgage Loans for
which it acts as Master Servicer) and each Special Servicer (with respect to
Specially Serviced Mortgage Loans for which it acts as Special Servicer), on
behalf of the Trustee as the mortgagee of record, shall enforce any
"due-on-sale" or "due-on-encumbrance" clauses and any other restrictions
contained in the related Mortgage or other related loan document on transfers or
further encumbrances of the related Mortgaged Property and on transfers of
interests in the related Borrower, unless the applicable Master Servicer or the
applicable Special Servicer, as the case may be, has (i) determined, in its
reasonable judgment, that waiver of such restrictions would be in accordance
with the Servicing Standard and (ii) complied with the applicable requirements,
if any, of Section 3.20(a), Section 3.23, Section 3.24 and Section 3.27;
provided that, subject to the related Mortgage Loan Documents and applicable
law, neither the applicable Master Servicer nor the applicable Special Servicer
shall waive any right it has, or grant any consent it is otherwise entitled to
withhold, in accordance with any related "due-on-encumbrance" clause under any
Mortgage Loan (other than a Co-op Mortgage Loan as to which the NCBFSB
Subordinate Debt Conditions have been satisfied) until it has received written
confirmation from (i) Moody's, (ii) with respect to any Mortgage Loan with a
Stated Principal Balance that is one of the ten highest Stated Principal
Balances in the Mortgage Pool, Fitch, and (iii) with respect to any Mortgage
Loan (A) with a Stated Principal Balance that is one of the ten highest Stated
Principal Balances in the Mortgage Pool, (B) has a Cut-off Date Principal
Balance in excess of $18,000,000, (C) represents more than 5% of the Mortgage
Pool, (D) has an aggregate debt service coverage ratio less than 1.20x or (E)
has an aggregate loan-to-value ratio greater than 85%, S&P, that such action
would not result in an Adverse Rating Event with respect to any Class of Rated
Certificates; and provided, further, that, if the affected Mortgage Loan,
individually or together with all other Mortgage Loans, if any, that are in the
same Cross-Collateralized Group as such Mortgage Loan (i) with a Stated
Principal Balance that is one of the ten highest Stated Principal Balances in
the Mortgage Pool, (ii) has a Cut-off Date Principal Balance in excess of
$18,000,000 or (iii) represents more than 5% of the Mortgage Pool, then, subject
to the related Mortgage Loan Documents and applicable law, neither the
applicable Master Servicer nor the applicable Special Servicer shall waive any
right it has, or grant any consent it is otherwise entitled to withhold, in
accordance with any related "due-on-sale" clause under any Mortgage Loan until
it has received written confirmation from each Rating Agency that such action
would not result in an Adverse Rating Event with respect to any Class of Rated
Certificates; and provided, further, that, subject to the related Mortgage Loan
Documents and applicable law, the applicable Master Servicer shall not waive any
right it has, or grant any consent it is otherwise entitled to withhold, in
accordance with any related "due-on-encumbrance" clause under any Mortgage Loan
(other than a Co-op Mortgage Loan as to which the NCBFSB Subordinate Debt
Conditions have been satisfied) until it has delivered to the applicable Special
Servicer its recommendation and analysis of the request, together with a copy of
the materials and information upon which such recommendation is based, and has
received the consent of the applicable Special Servicer (the giving of which
consent shall be subject to the Servicing Standard and Sections 3.23, 3.24 and
3.27), which consent shall be deemed given if not denied in writing within 10
Business Days of receipt by the applicable Special Servicer of the applicable
Master Servicer's written recommendation and analysis and any additional
information requested by the applicable Special Servicer or the Controlling
Class Representative; and provided, further, that, subject to the related
Mortgage Loan Documents and applicable law, the applicable Master Servicer shall
not waive any right it has, or grant any consent it is otherwise entitled to
withhold, in accordance with any related "due-on-sale" clause under any Mortgage
Loan until it has received the consent of the applicable Special Servicer (the
giving of which consent shall be subject to the Servicing Standard and Section
3.24), which consent shall be deemed given if not denied in writing within 10
Business Days of receipt by the applicable Special Servicer of the applicable
Master Servicer's written recommendation and analysis and any additional
information requested by the applicable Special Servicer or the Controlling
Class Representative; and provided, further, that, subject to the related
Mortgage Loan Documents and applicable law, neither the applicable Master
Servicer nor the applicable Special Servicer shall waive any right it has, or
grant any consent it is otherwise entitled to withhold, in accordance with any
related "due-on-sale" or "due-on-encumbrance" clause under any Mortgage Loan, or
approve the assumption of any Mortgage Loan, unless in any such case, all
associated costs and expenses are covered without any expense to the Trust (it
being understood and agreed that, except as expressly provided herein, neither
such Master Servicer nor such Special Servicer shall be obligated to cover or
assume any such costs or expenses); and provided, further, that neither the
applicable Master Servicer nor the applicable Special Servicer shall (to the
extent that it is within the control thereof to prohibit such event) consent to
the transfer of any Mortgaged Property which secures a Cross-Collateralized
Group unless (i) all of the Mortgaged Properties securing such
Cross-Collateralized Group are transferred simultaneously by the respective
Borrower or (ii) it obtains the consent of the Controlling Class Representative,
which consent shall be deemed given if not denied in writing within 10 Business
Days of receipt by the Controlling Class Representative of written notice of
such action and all reasonably requested information related thereto (or, if no
information is requested within ten (10) Business Days of receipt of written
notice). In the case of any Mortgage Loan, the applicable Master Servicer and
the applicable Special Servicer shall each provide the other with all such
information as each may reasonably request in order to perform its duties under
this section.

            In connection with any permitted assumption of any Mortgage Loan or
waiver of a "due-on-sale" or "due-on-encumbrance" clause thereunder, each Master
Servicer (in the case of a Performing Mortgage Loan for which it acts as Master
Servicer) or each Special Servicer (in the case of a Specially Serviced Mortgage
Loan for which it acts Special Servicer) shall prepare all documents necessary
and appropriate for such purposes and shall coordinate with the related Borrower
for the due execution and delivery of such documents.

            Notwithstanding the foregoing, and regardless of whether a
particular Co-op Mortgage Loan contains specific provisions regarding the
incurrence of subordinate debt, or prohibits the incurrence of subordinate debt,
or requires the consent of the Mortgagee in order to incur subordinate debt, the
NCBFSB Master Servicer may, nevertheless, in accordance with the Servicing
Standard, without the need to obtain any consent hereunder (and without the need
to obtain a ratings confirmation), permit the related Borrower to incur
subordinate debt if the NCBFSB Subordinate Debt Conditions have been met (as
certified in writing to the Trustee and the Controlling Class Representative by
the NCBFSB Master Servicer no later than five Business Days prior to the making
of the subject subordinate loan without right of reimbursement from the Trust)
which certification shall include notice of the circumstances of the waiver,
including information necessary for the Controlling Class Representative to
determine whether the NCBFSB Subordinate Debt Conditions have been satisfied);
provided that, subject to the related Mortgage Loan Documents and applicable
law, the NCBFSB Master Servicer shall not waive any right it has, or grant any
consent it is otherwise entitled to withhold, in accordance with any related
"due-on-encumbrance" clause under any Mortgage Loan, pursuant to this paragraph,
unless in any such case, all associated costs and expenses are covered without
any expense to the Trust.

            If a Master Servicer or a Special Servicer collects an assumption
fee or an assumption application fee in connection with any transfer or proposed
transfer of any interest in a Borrower or a Mortgaged Property, then such Master
Servicer or such Special Servicer, as applicable, will apply that fee to cover
the costs and expenses associated with that transfer or proposed transfer that
are not otherwise paid by the related Borrower and that would otherwise be
payable or reimbursable out of the Trust Fund, including any Rating Agency fees
and expenses to the extent such fees and expenses are collectible under
applicable law and the applicable Master Servicer or Special Servicer, as
appropriate, fails to enforce such requirement in accordance with the related
Mortgage Loan Documents. Any remaining portion of such assumption fee (such
remaining portion, a "Net Assumption Fee") or of such assumption application fee
(such remaining portion, a "Net Assumption Application Fee") will be applied as
additional compensation to the applicable Master Servicer or the applicable
Special Servicer in accordance with Section 3.11; provided, however, that with
respect to the Washington Center Total Loan, any Net Assumption Fee that is
payable to the related B Holder pursuant to the related A/B Intercreditor
Agreement shall be paid to the General Master Servicer and the General Special
Servicer in accordance with Section 3.11. It is hereby acknowledged that the
assumption application fee and the assumption fee paid in connection with the
assumption of the Mortgaged Property identified on the Mortgage Loan Schedule as
The Crossings, by Chelsea Pocono Finance, LLC on or about June 12, 2003, has
been retained by the Column Mortgage Loan Seller and shall not be payable to any
Master Servicer or any Special Servicer. Neither the applicable Master Servicer
nor the applicable Special Servicer shall waive any assumption fee or assumption
application fee, to the extent it would constitute additional compensation for
the other such party, without the consent of such other party.

            Section 3.09 Realization Upon Defaulted Mortgage Loans

            (a) Each Special Servicer shall, subject to Sections 3.09(b),
3.09(c), 3.09(d), 3.23, 3.24, 3.20 and 3.27, exercise reasonable efforts,
consistent with the Servicing Standard, to foreclose upon or otherwise
comparably convert the ownership of the real property and other collateral
securing any Mortgage Loan for which it acts as Special Servicer that comes into
and continues in default and as to which no satisfactory arrangements can be
made for collection of delinquent payments; provided that the applicable Master
Servicer shall not, with respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, take any enforcement action with respect to the payment of
Post-ARD Additional Interest (other than the making of requests for its
collection), and such Special Servicer may do so only if (i) the taking of an
enforcement action with respect to the payment of other amounts due under such
Mortgage Loan is, in the reasonable judgment of the Special Servicer, and
without regard to such Post-ARD Additional Interest, also necessary, appropriate
and consistent with the Servicing Standard or (ii) all other amounts due under
such Mortgage Loan have been paid, the payment of such Post-ARD Additional
Interest has not been forgiven in accordance with Section 3.20 and, in the
reasonable judgment of the Special Servicer, the Liquidation Proceeds expected
to be recovered in connection with such enforcement action will cover the
anticipated costs of such enforcement action and, if applicable, any associated
Advance Interest. In connection with the foregoing, in the event of a default
under any Mortgage Loan or Cross-Collateralized Group that is secured by real
properties located in multiple states, and such states include California or
another state with a statute, rule or regulation comparable to California's "one
action rule", then the applicable Special Servicer shall consult Independent
counsel regarding the order and manner in which the applicable Special Servicer
should foreclose upon or comparably proceed against such properties. The
reasonable costs of such consultation shall be paid by, and reimbursable to, the
applicable Special Servicer as a Servicing Advance. In addition, all other costs
and expenses incurred in any foreclosure sale or similar proceeding shall be
paid by, and reimbursable to, the applicable Special Servicer as a Servicing
Advance. Nothing contained in this Section 3.09 shall be construed so as to
require a Special Servicer, on behalf of the Trust, 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 such Special
Servicer taking into account the factors described in Section 3.18 and the
results of any appraisal obtained pursuant to the following sentence or
otherwise, all such cash bids to be made in a manner consistent with the
Servicing Standard. If and when a Special Servicer deems it necessary in
accordance with the Servicing Standard for purposes of establishing the fair
market value of any Mortgaged Property securing a defaulted Mortgage Loan for
which it acts as Special Servicer, whether for purposes of bidding at
foreclosure or otherwise, such Special Servicer is authorized to have an
Appraisal completed with respect to such property (the cost of which appraisal
shall be covered by, and be reimbursable as, a Servicing Advance).

            No Master Servicer or Special Servicer, other than the applicable
Special Servicer, shall foreclose upon or otherwise comparably convert,
including by taking title thereto, any real property or other collateral
securing a defaulted Mortgage Loan.

            (b) Notwithstanding the foregoing provisions of this Section 3.09,
no Mortgaged Property shall be acquired by a Special Servicer on behalf of the
Trust under such circumstances, in such manner or pursuant to such terms as
would (i) cause such Mortgaged Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code (unless the
portion of such REO Property that is not treated as "foreclosure property" and
that is held by the Lower-Tier REMIC or the 622 Third Avenue Loan REMIC at any
given time constitutes not more than a de minimis amount of the assets of such
Lower-Tier REMIC or such 622 Third Avenue Loan REMIC within the meaning of
Treasury Regulations Section 1.860D-1(b)(3)(i) and (ii)), or (ii) except as
permitted by Section 3.17(a), subject the Trust to the imposition of any federal
income or prohibited transaction taxes under the Code. Subject to the foregoing,
however, a Mortgaged Property may be acquired through a single member limited
liability company or similar entity. In addition, except as permitted under
Section 3.17(a), a Special Servicer shall not acquire any personal property on
behalf of the Trust 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 such Special
      Servicer; or

            (ii) such Special Servicer shall have obtained an Opinion of Counsel
      (the cost of which shall be covered by, and reimbursable to the applicable
      Master Servicer as, a Servicing Advance) to the effect that the holding of
      such personal property as part of the Trust Fund will not result in an
      Adverse REMIC Event with respect to the Upper-Tier REMIC, the Lower-Tier
      REMIC or the 622 Third Avenue Loan REMIC or in an Adverse Grantor Trust
      Event with respect to the Grantor Trust.

            (c) Notwithstanding the foregoing provisions of this Section 3.09, a
Special Servicer shall not, on behalf of the Trust, obtain title to a Mortgaged
Property by foreclosure, deed in lieu of foreclosure or otherwise, or take any
other action with respect to any Mortgaged Property, if, as a result of any such
action, the Trustee, on behalf of the Certificateholders (and, in the case of an
A/B Loan Pair, the related B Loan Holder or the Washington Center Junior
Holders) or any other specified person, could, in the reasonable judgment of the
applicable Special Servicer, exercised in accordance with the Servicing
Standard, be considered to hold title to, to be a "mortgagee-in-possession" of,
or to be an "owner" or "operator" of such Mortgaged Property within the meaning
of CERCLA or any comparable law, unless:

            (i) such Special Servicer has previously determined in accordance
      with the Servicing Standard, based on a Phase I Environmental Assessment
      (and any additional environmental testing that the Special Servicer deems
      necessary and prudent) of such Mortgaged Property conducted by an
      Independent Person who regularly conducts Phase I Environmental
      Assessments and performed during the 12-month period preceding any such
      acquisition of title or other action, that such Mortgaged Property is in
      compliance with applicable environmental laws and regulations and 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

            (ii) in the event that the determination described in clause (c)(i)
      above cannot be made, the applicable Special Servicer has previously
      determined in accordance with the Servicing Standard, on the same basis as
      described in clause (c)(i) above, and taking into account the coverage
      provided under the related Environmental Insurance Policy, that it would
      maximize the recovery to the Certificateholders (and the B Loan Holder and
      the Washington Center Junior Holders if in connection with a B Loan or the
      Washington Center Junior Loans, respectively, taken as a collective whole)
      on a present value basis (the relevant discounting of anticipated
      collections that will be distributable to Certificateholders and, if in
      connection with a B Loan or the Washington Center Junior Loans, the B Loan
      Holders and Washington Center Junior Holders, to be performed at the
      related Net Mortgage Rate) to acquire title to or possession of the
      Mortgaged Property and to take such remedial, corrective and/or other
      further actions as are necessary to bring the Mortgaged Property into
      compliance with applicable environmental laws and regulations and to
      appropriately address any of the circumstances and conditions referred to
      in clause (c)(i) above.

            Any such determination by a Special Servicer contemplated by clause
(i) or clause (ii) of the preceding paragraph shall be evidenced by an Officer's
Certificate to such effect delivered to the Trustee, the applicable Master
Servicer and the Controlling Class Representative, or, if in connection with the
622 Third Avenue Loan or the Washington Center Loan, to the 622 Third Avenue B
Loan Holder and each Washington Center Junior Holder, specifying all of the
bases for such determination, such Officer's Certificate to be accompanied by
all related environmental reports. The cost of such Phase I Environmental
Assessment and any such additional environmental testing shall be advanced by
the applicable Master Servicer at the direction of the applicable Special
Servicer in accordance with Section 3.19(b) given in accordance with the
Servicing Standard; provided, however, that the applicable Master Servicer shall
not be obligated in connection therewith to advance any funds which, if so
advanced, would constitute a Nonrecoverable Servicing Advance. Amounts so
advanced shall be subject to reimbursement as Servicing Advances in accordance
with Section 3.05(a). The cost of any remedial, corrective or other further
action contemplated by clause (ii) of the preceding paragraph shall be payable
out of the applicable Master Servicer's Collection Account pursuant to Section
3.05.

            (d) If neither of the conditions set forth in clauses (i) and (ii)
of the first paragraph of Section 3.09(c) has been satisfied with respect to any
Mortgaged Property securing a defaulted Mortgage Loan, the applicable Special
Servicer shall take such action as is in accordance with the Servicing Standard
(other than proceeding against the Mortgaged Property) and, at such time as it
deems appropriate, may, on behalf of the Trust, release all or a portion of such
Mortgaged Property from the lien of the related Mortgage; provided, however that
the applicable Special Servicer shall obtain confirmation from each Rating
Agency then rating the Certificates that no Adverse Rating Event shall exist
because of any such release.

            (e) Each Special Servicer shall report to the Trustee, the
applicable Master Servicer and the Controlling Class Representative, the 622
Third Avenue B Loan Holder (with respect to the 622 Third Avenue Loan) and each
Washington Center Junior Holder (with respect to the Washington Center Loan)
monthly in writing as to any actions taken by such Special Servicer with respect
to any Mortgaged Property as to which neither of the conditions set forth in
clauses (i) and (ii) of the first paragraph of Section 3.09(c) has been
satisfied, in each case until the earliest to occur of satisfaction of either of
such conditions, release of the lien of the related Mortgage on such Mortgaged
Property and the related Mortgage Loan's becoming a Corrected Mortgaged Loan;
provided, however, that in respect of the 622 Third Avenue Loan and the
Washington Center Loan, the applicable Special Servicer shall, before releasing
the lien of the related Mortgage on the related Mortgaged Properties satisfy the
conditions set forth in Section 3.27(b).

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

            (g) Annually in each January, each Special Servicer shall on a
timely basis forward to the applicable Master Servicer, who shall promptly file
same with the IRS on a timely basis, the information returns with respect to the
reports of foreclosures and abandonments and reports relating to any
cancellation of indebtedness income with respect to any Mortgage Loan or
Mortgaged Property required by Sections 6050H (as applicable), 6050J and 6050P
of the Code. Contemporaneously, each Special Servicer shall deliver to the
applicable Master Servicer, who shall promptly forward it to the Trustee, an
Officer's Certificate stating that all such information returns relating to any
Specially Serviced Mortgage Loan or REO Property that were required to be filed
during the prior twelve (12) months have been properly completed and timely
provided to such Master Servicer. Each Master Servicer shall prepare and file
the information returns with respect to the receipt of any mortgage interest
received in a trade or business from individuals with respect to any Mortgage
Loan for which it acts as Master Servicer as required by Section 6050H of the
Code. All information returns shall be in form and substance sufficient to meet
the reporting requirements imposed by the relevant sections of the Code.

            (h) As soon as the applicable Special Servicer (or, in the case of
the Great Lakes Crossing Mortgage Loan or any Great Lakes Crossing REO Property,
the Master Servicer) makes, in consultation with the Controlling Class
Representative, a Final Recovery Determination with respect to any Mortgage Loan
or REO Property, it shall promptly notify the Trustee, the applicable Master
Servicer, the Controlling Class Representative, the 622 Third Avenue B Loan
Holder (with respect to the 622 Third Avenue Loan) and each Washington Center
Junior Holder (with respect to the Washington Center Loan). Each Special
Servicer shall maintain accurate records, prepared by a Servicing Officer, of
each such Final Recovery Determination (if any) made by it and the basis
thereof. Each such Final Recovery Determination (if any) shall be evidenced by
an Officer's Certificate delivered to the Trustee, the applicable Master
Servicer, the Controlling Class Representative, the 622 Third Avenue B Loan
Holder and each Washington Center Junior Holder no later than the third Business
Day following such Final Recovery Determination.

            Section 3.10 Trustee to Cooperate; Release of Mortgage Files

            (a) Upon the payment in full of any Mortgage Loan, the purchase of
an A Loan by the B Loan Holder or any Washington Center Junior Holder, as
applicable, pursuant to the related A/B Intercreditor Agreement or the receipt
by a Master Servicer of a notification that payment in full shall be escrowed or
made in a manner customary for such purposes, such Master Servicer shall
promptly so notify the Trustee and request delivery to it or its designee of the
related Mortgage File (such notice and request to be effected by delivering to
the Trustee a Request for Release in the form of Exhibit D-1 attached hereto,
which Request for Release shall be accompanied by the form of any release or
discharge to be executed by the Trustee 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 such Master Servicer's Collection
Account or an A/B Loan Pair Custodial Account pursuant to Section 3.04(a) have
been or will be so deposited). Upon receipt of such Request for Release, the
Trustee shall promptly release, or cause any related Custodian to release, the
related Mortgage File to the applicable Master Servicer or its designee and
shall deliver to the applicable Master Servicer or its designee such
accompanying release or discharge, duly executed. No expenses incurred in
connection with any instrument of satisfaction or deed of reconveyance shall be
chargeable to a Collection Account, an A/B Loan Pair Custodial Account or the
Distribution Account.

            (b) If from time to time, and as appropriate for servicing or
foreclosure of any Mortgage Loan, 622 Third Avenue Total Loan or Washington
Center Total Loan, a Master Servicer or a Special Servicer shall otherwise
require any Mortgage File (or any portion thereof), then, upon request of the
applicable Master Servicer and receipt from such Master Servicer of a Request
for Release in the form of Exhibit D-1 attached hereto signed by a Servicing
Officer thereof, or upon request of the applicable Special Servicer and receipt
from the applicable Special Servicer of a Request for Release in the form of
Exhibit D-2 attached hereto, the Trustee shall release, or cause any related
Custodian to release, such Mortgage File (or portion thereof) to the applicable

designee. Upon return of such Mortgage File (or portion thereof) to the Trustee
or the related Custodian, or upon the applicable Special Servicer's delivery to
the Trustee of an Officer's Certificate stating that (i) such Mortgage Loan, 622
Third Avenue Total Loan or Washington Center Total Loan was liquidated and all
amounts received or to be received in connection with such liquidation that are
required to be deposited into a Collection Account or an A/B Loan Pair Custodial

deposited or (ii) such Mortgage Loan, 622 Third Avenue Total Loan or Washington
Center Total Loan has become an REO Property, a copy of the Request for Release
shall be returned by the Trustee to the applicable Master Servicer or the
applicable Special Servicer, as applicable.

            (c) Within five Business Days of a Special Servicer's request
therefor (or, if such Special Servicer notifies the Trustee of an exigency,
within such shorter period as is reasonable under the circumstances), the
Trustee shall execute and deliver to such Special Servicer, in the form supplied
to the Trustee by such Special Servicer, any court pleadings, requests for
trustee's sale or other documents reasonably necessary to the foreclosure or
trustee's sale in respect of a Mortgaged Property or to any legal action brought

provided by the Mortgage Note or Mortgage or otherwise available at law or in
equity or to defend any legal action or counterclaim filed against the Trust,
the applicable Master Servicer or the applicable Special Servicer; provided that
the Trustee may alternatively execute and deliver to the applicable Special
Servicer, in the form supplied to the Trustee by such Special Servicer, a
limited power of attorney issued in favor of such Special Servicer and
empowering such Special Servicer to execute and deliver any or all of such
pleadings or documents on behalf of the Trustee (however, the Trustee shall not
be liable for any misuse of such power of attorney by such Special Servicer).
Together with such pleadings or documents (or such power of attorney empowering
such Special Servicer to execute the same on behalf of the Trustee), the
applicable Special Servicer shall deliver to the Trustee an Officer's
Certificate requesting that such pleadings or documents (or such power of
attorney empowering such Special Servicer to execute the same on behalf of the
Trustee) be executed by the Trustee and certifying as to the reason such
pleadings or documents are required and that the execution and delivery thereof
by the Trustee (or by such Special Servicer on behalf of 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.

            (d) From time to time as is appropriate for servicing or foreclosure
of any B Loan or Washington Center Junior Loan, the applicable Master Servicer,
the applicable Special Servicer or the Trustee, as applicable, subject to the
related A/B Intercreditor Agreement, may request the original of the related
promissory note from the related B Loan Holder or Washington Center Junior
Holders, respectively. Any B Loan Holder or any Washington Center Junior Holder
shall release or cause the release of such original Mortgage Note to the
requesting party or its designee. In connection with the release of the original
Mortgage Note for the any B Loan or any Washington Center Junior Loan in
accordance with the preceding sentence, the Trustee shall obtain such
documentation as is appropriate to evidence the holding by the applicable Master
Servicer or the applicable Special Servicer of such original Mortgage Note as
custodian on behalf of and for the benefit of the Trustee.

            (e) If from time to time, pursuant to the terms of the Great Lakes
Crossing Intercreditor Agreement and any Great Lakes Crossing Servicing
Agreement, and as appropriate for enforcing the terms of the Great Lakes
Crossing Mortgage Loan, the Great Lakes Crossing Master Servicer, the Great
Lakes Crossing Special Servicer or the holder of the Great Lakes Crossing
Companion Loan requests delivery to it of the original Mortgage Note for the
Great Lakes Crossing Mortgage Loan, then the Trustee shall release or cause the
release of such original Mortgage Note to the requesting party or its designee.
In connection with the release of the original Mortgage Note for the Great Lakes
Crossing Mortgage Loan in accordance with the preceding sentence, the Trustee
shall obtain such documentation as is appropriate to evidence the holding by the
Great Lakes Crossing Master Servicer, the Great Lakes Crossing Special Servicer
or the holder of the Great Lakes Crossing Companion Loan of such original
Mortgage Note as custodian on behalf of and for the benefit of the Trustee.

            Section 3.11 Master Servicing and Special Servicing Compensation;
Interest on and Reimbursement of Servicing Advances; Payment of Certain
Expenses; Obligations of the Trustee and any Fiscal Agent Regarding Back-up
Servicing Advances

            (a) As compensation for its activities hereunder, each Master
Servicer shall be entitled to receive the Master Servicing Fee with respect to
each Mortgage Loan (including the Great Lakes Crossing Mortgage Loan, the 622
Third Avenue B Loan, the Washington Center C Loan and each Specially Serviced
Mortgage Loan) as to which it is the applicable Master Servicer and each REO
Mortgage Loan that relates to an REO Property as to which it is the applicable
Master Servicer. As to each Mortgage Loan, 622 Third Avenue B Loan, Washington
Center C Loan and REO Mortgage Loan, for each calendar month (commencing with
June 2003) or any applicable portion thereof, the Master Servicing Fee shall
accrue at the related Master Servicing Fee Rate on the same principal amount as
interest accrues from time to time during such calendar month (or portion
thereof) on such Mortgage Loan, 622 Third Avenue B Loan or Washington Center C
Loan, as applicable, or is deemed to accrue from time to time during such
calendar month (or portion thereof) on such REO Mortgage Loan, as the case may
be, and shall be calculated on the same Interest Accrual Basis as is applicable
for such Mortgage Loan, 622 Third Avenue B Loan, Washington Center C Loan or REO
Mortgage Loan, as the case may be. The Master Servicing Fee with respect to any
Mortgage Loan, 622 Third Avenue B Loan, Washington Center C Loan or REO Mortgage
Loan shall cease to accrue if a Liquidation Event occurs in respect thereof.
Master Servicing Fees earned with respect to any Mortgage Loan, 622 Third Avenue
B Loan, Washington Center C Loan or REO Mortgage Loan shall be payable monthly
from payments of interest on such Mortgage Loan, 622 Third Avenue B Loan,
Washington Center C Loan or REO Revenues allocable as interest on such REO
Mortgage Loan, as the case may be other than from interest payable on the
Washington Center B Loan prior to an event of default on such loan. The
Servicing Fee with respect to the 622 Third Avenue Loan shall be an expense of
the 622 Third Avenue Loan REMIC. Each Master Servicer shall be entitled to
recover unpaid Master Servicing Fees in respect of any Mortgage Loan, 622 Third
Avenue B Loan, Washington Center C Loan or REO Mortgage Loan for which it acts
as Master Servicer out of the portion any related Insurance Proceeds,
Condemnation Proceeds or Liquidation Proceeds allocable as interest on such
Mortgage Loan, 622 Third Avenue B Loan, Washington Center C Loan or REO Mortgage
Loan, as the case may be other than from interest payable on the Washington
Center B Loan prior to an event of default on such loan.

            NCBFSB and any successor holder of the Excess Servicing Fee Rights
that relate to the NCBFSB Serviced Mortgage Loans (and any successor REO
Mortgage Loans with respect to such NCBFSB Serviced Mortgage Loans) shall be
entitled, at any time, at its own expense, to transfer, sell, pledge or
otherwise assign such Excess Servicing Fee Rights in whole (but not in part),
and KRECM and any successor holder of the Excess Servicing Fee Rights that
relate to the General Mortgage Loans (and any successor REO Mortgage Loans with
respect to such other Mortgage Loans) shall be entitled, at any time at its own
expense, to transfer, sell, pledge or otherwise assign such Excess Servicing Fee
Rights in whole (but not in part), in either case, to any Qualified
Institutional Buyer or Institutional Accredited Investor (other than a Plan),
provided that no such transfer, sale, pledge or other assignment shall be made
unless (i) that transfer, sale, pledge or other assignment is exempt from the
registration and/or qualification requirements of the Securities Act and any
applicable state securities laws and is otherwise made in accordance with the
Securities Act and such state securities laws, (ii) the prospective transferor
shall have delivered to the Depositor a certificate substantially in the form
attached as Exhibit F-3A hereto, and (iii) the prospective transferee shall have
delivered to KRECM or NCBFSB, as applicable, and the Depositor a certificate
substantially in the form attached as Exhibit F-3B hereto. None of the
Depositor, the Trustee or the Certificate Registrar is obligated to register or
qualify an Excess Servicing Fee Right under the Securities Act or any other
securities law or to take any action not otherwise required under this Agreement
to permit the transfer, sale, pledge or assignment of an Excess Servicing Fee
Right without registration or qualification. KRECM, NCBFSB and each holder of an
Excess Servicing Fee Right desiring to effect a transfer, sale, pledge or other
assignment of such Excess Servicing Fee Right shall, and each of KRECM and
NCBFSB hereby agrees, and each such holder of an Excess Servicing Fee Right by
its acceptance of such Excess Servicing Fee Right shall be deemed to have
agreed, in connection with any transfer of such Excess Servicing Fee Right
effected by such Person, to indemnify the Certificateholders, the Trust, the
Depositor, the Underwriters, the Trustee, any Fiscal Agent, the Master
Servicers, the Certificate Registrar and the Special Servicers against any
liability that may result if such transfer is not exempt from registration
and/or qualification under the Securities Act or other applicable federal and
state securities laws or is not made in accordance with such federal and state
laws or in accordance with the foregoing provisions of this paragraph. By its
acceptance of an Excess Servicing Fee Right, the holder thereof shall be deemed
to have agreed (i) to keep all information relating to the Trust and the Trust
Fund and made available to it by the Master Servicers confidential (except as
permitted pursuant to clause (iii) below or, in the case of the Master
Servicers, as contemplated hereby in the performance of its duties and
obligations hereunder), (ii) not to use or disclose such information in any
manner that could result in a violation of any provision of the Securities Act
or other applicable securities laws or that would require registration of such
Excess Servicing Fee Right or any Non-Registered Certificate pursuant to the
Securities Act, and (iii) not to disclose such information, and to cause its
officers, directors, partners, employees, agents or representatives not to
disclose such information, in any manner whatsoever, in whole or in part, to any
other Person other than such holder's auditors, legal counsel and regulators,
except to the extent such disclosure is required by law, court order or other
legal requirement or to the extent such information is of public knowledge at
the time of disclosure by such holder or has become generally available to the
public other than as a result of disclosure by such holder; provided, however,
that such holder may provide all or any part of such information to any other
Person who is contemplating an acquisition of such Excess Servicing Fee Right
if, and only if, such Person (x) confirms in writing such prospective
acquisition and (y) agrees in writing to keep such information confidential, not
to use or disclose such information in any manner that could result in a
violation of any provision of the Securities Act or other applicable securities
laws or that would require registration of such Excess Servicing Fee Right or
any Non-Registered Certificates pursuant to the Securities Act and not to
disclose such information, and to cause its officers, directors, partners,
employees, agents or representatives not to disclose such information, in any
manner whatsoever, in whole or in part, to any other Person other than such
Persons' auditors, legal counsel and regulators. From time to time following any
transfer, sale, pledge or assignment of an Excess Servicing Fee Right, the
Person then acting as the Master Servicer with respect to the Mortgage Loan or
REO Mortgage Loan to which the Excess Servicing Fee Right relates, shall pay,
out of each amount paid to the applicable Master Servicer as Master Servicing
Fees with respect to such Mortgage Loan or REO Mortgage Loan, as the case may
be, the related Excess Servicing Fees to the holder of such Excess Servicing Fee
Right within one Business Day following the payment of such Master Servicing
Fees to the applicable Master Servicer, in each case in accordance with payment
instructions provided by such holder in writing to such Master Servicer. The
holder of an Excess Servicing Fee Right shall not have any rights under this
Agreement except as set forth in the preceding sentences of this paragraph.
Neither the Certificate Registrar nor the Trustee shall have any obligation
whatsoever regarding payment of an Excess Servicing Fee or the assignment or
transfer of an Excess Servicing Fee Right.

            The applicable Master Servicer shall be entitled to the Servicing
Fee with respect to the 622 Third Avenue B Loan and Washington Center C Loan as
described in the second preceding paragraph; provided that, in no such case,
shall the payment of any such compensation reduce amounts otherwise payable to
the Certificateholders with respect to the related A Loan.

            A Master Servicer's right to receive the Master Servicing Fees to
which it is entitled may not be transferred in whole or in part except in
connection with the transfer of all of such Master Servicer's responsibilities
and obligations under this Agreement and except as otherwise expressly provided
herein, including as contemplated by the prior paragraph.

            (b) Each Master Servicer shall be entitled to receive the following
items with respect to the Mortgage Loans for which it acts as Master Servicer as
additional servicing compensation (the following items, collectively,
"Additional Master Servicing Compensation"):

            (i) any and all Net Default Charges collected with respect to a
      Performing Mortgage Loan;

            (ii) 50% of any and all Net Assumption Application Fees, Net
      Assumption Fees, modification fees, extension fees, consent fees, release
      fees, waiver fees, fees paid in connection with defeasance and earn-out
      fees actually paid by a Borrower with respect to a Performing Mortgage
      Loan provided, however, that if the consent of the Special Servicer is not
      required in connection with the underlying servicing action, then the
      applicable Master Servicer shall be entitled to receive 100% of such fees;

            (iii) any and all charges for beneficiary statements or demands,
      amounts collected for checks returned for insufficient funds and other
      loan processing fees actually paid by a Borrower with respect to a
      Performing Mortgage Loan and, in the case of checks returned for
      insufficient funds, with respect to a Specially Serviced Mortgage Loan;

            (iv) any and all Prepayment Interest Excesses collected with respect
      to a Mortgage Loan, including a Specially Serviced Mortgage Loan, to the
      extent not needed to pay Compensating Interest Payments; and

            (v) interest or other income earned on deposits in the Investment
      Accounts maintained by such Master Servicer, in accordance with Section
      3.06(b) (but only to the extent of the Net Investment Earnings, if any,
      with respect to any such Investment Account for each Collection Period
      and, further, in the case of a Servicing Account or Reserve Account, only
      to the extent such interest or other income is not required to be paid to
      any Borrower under applicable law or under the related Mortgage).

            The Master Servicers shall not be entitled to any Master Servicing
Fees or any other compensation from the Trust Fund hereunder with respect to the
B Loans that relate to any CBA A/B Loan Pair.

            The applicable Master Servicer shall be entitled to the
above-described Additional Servicing Compensation with respect to the B Loans
and the Washington Center Junior Loans to the extent not expressly prohibited
under the respective A/B Intercreditor Agreements; provided that, in no such
case, shall the payment of any such compensation reduce amounts otherwise
payable to the Certificateholders with respect to the related A Loan.

            Any Net Assumption Fee received by the General Master Servicer (A)
in respect of the 622 Third Avenue Total Loan shall be allocated between and
distributed to the Trust as holder of the 622 Third Avenue Loan (which amount
shall be payable to the General Master Servicer and General Special Servicer in
accordance with this Section 3.11) and the 622 Third Avenue B Loan Holder based
on the respective percentage interests in the 622 Third Avenue Total Loan as set
forth in the related A/B Intercreditor Agreement and (B) in respect of the
Washington Center Total Loan shall be allocated among and distributed to the
Trust as holder of the Washington Center Loan (which amount shall be payable to
the General Master Servicer and General Special Servicer in accordance with this
Section 3.11) and to the Washington Center Junior Holders based on the
respective percentage interests in the Washington Center Total Loan as set forth
in the related A/B Intercreditor Agreement; provided, however that any such Net
Assumption Fee allocated to the holder of the Washington Center B Loan shall be
payable to the General Master Servicer or Special Servicer, as applicable.

            To the extent that any of the amounts described in clauses (i)
through (v) in the preceding paragraph are collected by a Special Servicer, such
Special Servicer shall promptly pay such amounts to the applicable Master
Servicer.

            (c) As compensation for its activities hereunder, subject to the
proviso to clause (d) of the definition of "Servicing Transfer Event", each
Special Servicer shall be entitled to receive monthly the Special Servicing Fee
with respect to each Specially Serviced Mortgage Loan and each REO Mortgage Loan
(other than any Great Lakes Crossing REO Mortgage Loan) for which it acts as
Special Servicer. As to each such Specially Serviced Mortgage Loan and REO
Mortgage Loan (other than any Great Lakes Crossing REO Mortgage Loan), for any
particular calendar month or applicable portion thereof, the Special Servicing
Fee shall accrue at the Special Servicing Fee Rate on the same principal amount
as interest accrues from time to time during such calendar month (or portion
thereof) on such Specially Serviced Mortgage Loan or is deemed to accrue from
time to time during such calendar month (or portion thereof) on such REO
Mortgage Loan, as the case may be, and shall be calculated on the same Interest
Accrual Basis as is applicable for such Specially Serviced Mortgage Loan or REO
Mortgage Loan (other than any Great Lakes Crossing REO Mortgage Loan), as the
case may be. The Special Servicing Fee with respect to any Specially Serviced
Mortgage Loan or REO Mortgage Loan (other than any Great Lakes Crossing REO
Mortgage Loan) shall cease to accrue as of the date a Liquidation Event occurs
in respect thereof or, in the case of a Specially Serviced Mortgage Loan, as of
the date it becomes a Corrected Mortgage Loan. Earned but unpaid Special
Servicing Fees shall be payable first out of related Liquidation Proceeds and
then monthly out of general collections on the Mortgage Loans and any REO
Properties on deposit in the applicable Master Servicer's Collection Account
pursuant to Section 3.05(a).

            As further compensation for its activities hereunder, each Special
Servicer shall be entitled to receive the Workout Fee with respect to each
Corrected Mortgage Loan. As to each such Corrected Mortgage Loan, the Workout
Fee shall be payable out of, and shall be calculated by application of the
Workout Fee Rate to, (i) each payment of interest (other than Default Interest)
and principal received from the related Borrower on such Mortgage Loan for so
long as it remains a Corrected Mortgage Loan. The Workout Fee with respect to
any Corrected Mortgage Loan will cease to be payable if a Servicing Transfer
Event occurs with respect thereto or if the related Mortgaged Property becomes
an REO Property; provided that a new Workout Fee would become payable if and
when such Mortgage Loan again became a Corrected Mortgage Loan with respect to
such new Servicing Transfer Event. If a Special Servicer is terminated (other
than for cause), including pursuant to Section 3.25, or resigns in accordance
with Section 6.04, it shall retain the right to receive any and all Workout Fees
payable in respect of (i) any Mortgage Loans for which it acted as Special
Servicer, that became Corrected Mortgage Loans during the period that it acted
as Special Servicer and that were still Corrected Mortgage Loans at the time of
such termination or resignation and (ii) any Specially Serviced Mortgage Loans
with respect to which it acted as Special Servicer for which the Special
Servicer has resolved the circumstances and/or conditions causing such Mortgage
Loan to be a Specially Serviced Mortgage Loan, but which had not as of the time
it was terminated or resigned become a Corrected Mortgage Loan solely because
the related Borrower had not made three consecutive timely Monthly Payments and
which subsequently becomes a Corrected Mortgage Loan as a result of the related
Borrower making such three consecutive timely Monthly Payments (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 preceding sentence; provided that, in the case of any
Specially Serviced Mortgage Loan described in clause (ii) of this sentence, the
terminated Special Servicer shall immediately deliver the related Servicing File
to the applicable Master Servicer, and such Master Servicer shall (without
further compensation) monitor that all conditions precedent to such Mortgage
Loan's becoming a Corrected Mortgage Loan are satisfied and, further, shall
immediately transfer such Servicing File to the new applicable Special Servicer
if and when it becomes apparent to such Master Servicer that such conditions
precedent will not be satisfied.

            As further compensation for its activities hereunder, each Special
Servicer shall also be entitled to receive a Liquidation Fee with respect to
each Specially Serviced Mortgage Loan with respect to which it acts as Special
Servicer or REO Property related thereto as to which it receives any full,
partial or discounted payoff from the related Borrower or any Condemnation
Proceeds or Liquidation Proceeds (other than any receipt of Liquidation Proceeds
with respect to a Specially Serviced Mortgage Loan or REO Property that is (i)
purchased by the Special Servicer or any Holders of Certificate(s) of a
Controlling Class or any assignee of the foregoing pursuant to Section 3.18;
provided that if any such party assigns their Purchase Option to an unaffiliated
third party without any consideration therefor (other than nominal
consideration), a Liquidation Fee shall be payable pursuant to Section 3.11,
(ii) purchased by a Master Servicer, a Special Servicer or any
Certificateholder(s) of the Controlling Class pursuant to Section 9.01, (iii)
acquired by the Sole Certificateholder(s) in exchange for all the Certificates
pursuant to Section 9.01, (iv) purchased by the related B Loan Holder or any
Washington Center Junior Holder pursuant to the related A/B Intercreditor
Agreement so long as such Specially Serviced Mortgage Loan or REO Property is
purchased within the time period specified in such related A/B Intercreditor
Agreement (v) purchased by a mezzanine lender pursuant to the mezzanine
intercreditor agreement; provided that if such mezzanine intercreditor agreement
provides for the payment of a liquidation fee, such fee shall be payable, or
(vi) repurchased or replaced no later than the end of the applicable Initial
Resolution Period and any applicable Resolution Extension Period, as a result of
a Material Breach or a Material Document Defect, by a Mortgage Loan Seller
pursuant to the related Mortgage Loan Purchase Agreement or by the Column
Performance Guarantor pursuant to the Column Performance Guarantee). As to each
such Specially Serviced Mortgage Loan or REO Property, the Liquidation Fee shall
be payable out of, and shall be calculated by application of the Liquidation Fee
Rate to, any such full, partial or discounted payoff, Condemnation Proceeds
and/or Liquidation Proceeds received or collected in respect thereof (other than
any portion of such payment or proceeds that represents Post-ARD Additional
Interest, Default Charges, a Prepayment Premium or a Yield Maintenance Charge).
Notwithstanding the foregoing, no Liquidation Fee shall be payable under this
Agreement based on, or out of, Liquidation Proceeds received in connection with
any Liquidation Event involving the Great Lakes Crossing Mortgage Loan or any
Great Lakes Crossing REO Property. The Liquidation Fee with respect to any such
Specially Serviced Mortgage Loan shall not be payable if such Mortgage Loan
becomes a Corrected Mortgage Loan. Notwithstanding anything herein to the
contrary, no Liquidation Fee shall be payable in connection with the receipt of,
or out of, Liquidation Proceeds and, with respect to the Washington Center Loan,
Condemnation Proceeds, collected as a result of the purchase or substitution of
any Specially Serviced Mortgage Loan or REO Property described in the
parenthetical to the first sentence of this paragraph.

            A Special Servicer's right to receive any Special Servicing Fee,
Workout Fee and/or Liquidation Fee to which it is entitled may not be
transferred in whole or in part except in connection with the transfer of all of
such Special Servicer's responsibilities and obligations under this Agreement
and except as otherwise expressly provided herein.

            (d) Each Special Servicer shall be entitled to receive the following
items as additional special servicing compensation (the following items,
collectively, the "Additional Special Servicing Compensation"):

            (i) any and all Net Default Charges collected with respect to a
      Specially Serviced Mortgage Loan or an REO Mortgage Loan (other than any
      Great Lakes Crossing REO Mortgage Loan);

            (ii) any and all Net Assumption Fees, Net Assumption Application
      Fees, modification fees, extension fees, consent fees, release fees,
      waiver fees, earn-out fees and charges for beneficiary statements or
      demands that are actually received on or with respect to a Specially
      Serviced Mortgage Loan or an REO Mortgage Loans (other than any Great
      Lakes Crossing REO Mortgage Loan);

            (iii) subject to the proviso in Section 3.11(b)(ii), 50% of any and
      all Net Assumption Fees, Net Assumption Application Fees, modification
      fees, extension fees, consent fees, release fees, waiver fees and earn-out
      fees that are actually received on or with respect to a Performing
      Mortgage Loan; and

            (iv) interest or other income earned on deposits in any REO Account
      maintained by such Special Servicer, in accordance with Section 3.06(b)
      (but only to the extent of the Net Investment Earnings, if any, with
      respect to such REO Account for each Collection Period).

            The applicable Special Servicer shall be entitled to such
compensation with respect to the B Loans and the Washington Center Junior Loans
as is provided under the respective A/B Intercreditor Agreements; provided that,
in no such case, shall the payment of any such compensation reduce amounts
otherwise payable to the Certificateholders with respect to the related A Loan.

            Any Net Assumption Fee received by the General Special Servicer (A)
in respect of the 622 Third Avenue Total Loan shall be distributed to the Trust
as holder of the 622 Third Avenue Loan and the 622 Third Avenue B Loan Holder
based on the respective percentage interests in the 622 Third Avenue Total Loan
as set forth in the related A/B Intercreditor Agreement and (B) in respect of
the Washington Center Total Loan shall be distributed to the Trust as holder of
the Washington Center Loan and to the Washington Center Junior Holders based on
the respective percentage interests in the Washington Center Total Loan as set
forth in the related A/B Intercreditor Agreement; provided, however that any
such Net Assumption Fee allocated to the holder of the Washington Center B Loan
shall be payable to the General Special Master or Special Servicer, as
applicable.

            To the extent that any of the amounts described in clauses (i)
through (iii) of the third preceding paragraph are collected by a Master
Servicer, such Master Servicer shall promptly pay such amounts to the applicable
Special Servicer and shall not be required to deposit such amounts in such
Master Servicer's Collection Account pursuant to Section 3.04(a).

            (e) Each Master Servicer and each Special Servicer shall be required
(subject to Section 3.11(h) below) to pay out of its own funds all expenses
incurred by it in connection with its servicing activities hereunder (including
payment of any amounts due and owing to any of Sub-Servicers retained by it
(including any termination fees) and the premiums for any blanket policy or the
standby fee or similar premium, if any, for any master force placed policy
obtained by it insuring against hazard losses pursuant to Section 3.07(b)), if
and to the extent such expenses are not payable directly out of any Collection
Account, A/B Loan Pair Custodial Account, Servicing Account, Reserve Account or
REO Account, and neither a Master Servicer nor a Special Servicer shall be
entitled to reimbursement for any such expense incurred by it except as
expressly provided in this Agreement. If a Master Servicer is required to make
any Servicing Advance hereunder at the discretion of the applicable Special
Servicer in accordance with Section 3.19 or otherwise, such Special Servicer
shall promptly provide such Master Servicer with such documentation regarding
the subject Servicing Advance as the applicable Master Servicer may reasonably
request.

            (f) If a Master Servicer or, as contemplated by Section 3.19(b), a
Special Servicer is required under this Agreement to make a Servicing Advance,
but fails to do so within ten days after such Advance is required to be made,
the Trustee shall, if it has actual knowledge of such failure on the part of the
applicable Master Servicer or the applicable Special Servicer, as the case may
be, give notice of such failure to the defaulting party. If such Advance is not
made by such Master Servicer or such Special Servicer within three Business Days
after such notice, then (subject to Section 3.11(h) below) the Trustee or a
Fiscal Agent appointed thereby shall make such Advance. If any Fiscal Agent
makes any such Servicing Advance, the Trustee shall be deemed not to be in
default under this Agreement for failing to do so.

            (g) Each Master Servicer, each Special Servicer, the Trustee and any
Fiscal Agent shall each be entitled to receive interest at the Reimbursement
Rate in effect from time to time, accrued on the amount of each Servicing
Advance made thereby (with its own funds), for so long as such Servicing Advance
is outstanding. Such interest with respect to any Servicing Advances shall be
payable: (i) first, in accordance with Sections 3.05 and 3.26, out of any
Default Charges subsequently collected on or in respect of the particular
Mortgage Loan or REO Mortgage Loan as to which such Servicing Advance relates;
and (ii) then, after such Servicing Advance is reimbursed, but only if and to
the extent that such Default Charges are insufficient to cover such Advance
Interest, out of general collections on the Mortgage Loans and REO Properties on
deposit in the applicable Master Servicer's Collection Account. Each Master
Servicer shall reimburse itself, the applicable Special Servicer, the Trustee or
any Fiscal Agent, as appropriate, for any Servicing Advance made by any such
Person with respect to any Mortgage Loan or REO Property as to which such Master
Servicer is the applicable Master Servicer as soon as practicable after funds
available for such purpose are deposited in such Master Servicer's Collection
Account. A Master Servicer shall not be entitled to Advance Interest on any
Servicing Advance made thereby to the extent a payment is received but is being
held by such Master Servicer in suspense.

            (h) Notwithstanding anything to the contrary set forth herein, none
of the Master Servicers, the Special Servicers, the Trustee or any Fiscal Agent
shall be required to make any Servicing Advance that it determines in its
reasonable judgment would constitute a Nonrecoverable Servicing Advance. The
determination by any Person with an obligation hereunder to make Servicing
Advances that it has made a Nonrecoverable Servicing Advance or that any
proposed Servicing Advance, if made, would constitute a Nonrecoverable Servicing
Advance, shall be made by such Person in its reasonable judgment and shall be
evidenced by an Officer's Certificate delivered promptly to the Depositor, the
Trustee (unless it is the Person making such determination), the Controlling
Class Representative, the 622 Third Avenue Loan Holder (with respect to the 622
Third Avenue Loan) and each Washington Center Junior Holder (with respect to the
Washington Center Loan) setting forth the basis for such determination,
accompanied by a copy of an Appraisal of the related Mortgaged Property or REO
Property performed within the 12 months preceding such determination, and
further accompanied by any other information, including engineers' reports,
environmental surveys or similar reports, that such Person may have obtained and
that support such determination. Notwithstanding the foregoing, the Trustee and
any Fiscal Agent shall be entitled to conclusively rely on any determination of
nonrecoverability that may have been made by the applicable Master Servicer or
the applicable Special Servicer with respect to a particular Servicing Advance
for any Mortgage Loan or REO Property, and the applicable Master Servicer and
the applicable Special Servicer shall each be entitled to conclusively rely on
any determination of nonrecoverability that may have been made by the other such
party with respect to a particular Servicing Advance for any Mortgage Loan or
REO Property. A copy of any such Officer's Certificate (and accompanying
information) of a Master Servicer shall also be delivered promptly to the
applicable Special Servicer for the subject Mortgage Loan or REO Property, a
copy of any such Officer's Certificate (and accompanying information) of a
Special Servicer shall also be promptly delivered to the applicable Master
Servicer for the subject Mortgage Loan or REO Property, and a copy of any such
Officer's Certificates (and accompanying information) of the Trustee or the
Fiscal Agent shall also be promptly delivered to the Controlling Class
Representative, the 622 Third Avenue Loan Holder (with respect to the 622 Third
Avenue Loan) and each Washington Center Junior Holder (with respect to the
Washington Center Loan) and the applicable Master Servicer and the applicable
Special Servicer for the subject Mortgage Loan or REO Property.

            (i) Notwithstanding anything to the contrary set forth herein, each
Master Servicer may (and, at the direction of the applicable Special Servicer if
a Specially Serviced Mortgage Loan or an REO Property is involved, shall) pay
directly out of such Master Servicer's Collection Account any servicing expense
that, if paid by such Master Servicer or the applicable Special Servicer, would
constitute a Nonrecoverable Servicing Advance for the subject Mortgage Loan or
REO Property; provided that such Master Servicer (or the applicable Special
Servicer, if a Specially Serviced Mortgage Loan or an REO Property is involved)
has determined in accordance with the Servicing Standard that making such
payment is in the best interests of the Certificateholders (as a collective
whole), as evidenced by an Officer's Certificate delivered promptly to the
Depositor, the Trustee and the Controlling Class Representative, setting forth
the basis for such determination and accompanied by any information that such
Person may have obtained that supports such determination. A copy of any such
Officer's Certificate (and accompanying information) of a Master Servicer shall
also be delivered promptly to the applicable Special Servicer for the subject
Mortgage Loan or REO Property, and a copy of any such Officer's Certificate (and
accompanying information) of a Special Servicer shall also be promptly delivered
to the applicable Master Servicer for the subject Mortgage Loan or REO Property.

            (j) If the Master Servicer and the Special Servicer are responsible
for servicing and administering the Great Lakes Crossing Total Loan or any Great
Lakes Crossing REO Property under Article XII, then each of the Master Servicer
and the Special Servicer shall be entitled to such compensation as is provided
for in Section 12.09, which shall be in addition to that provided for in this
Section 3.11.

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

            (a) The applicable Special Servicer shall perform or cause to be
performed a physical inspection of a Mortgaged Property as soon as practicable
(but in any event not later than 60 days) after the related Mortgage Loan
becomes a Specially Serviced Mortgage Loan (and, in cases where the related
Mortgage Loan has become a Specially Serviced Mortgage Loan, the applicable
Special Servicer shall continue to perform or cause to be performed a physical
inspection of the subject Mortgaged Property at least once per calendar year
thereafter for so long as the related Mortgage Loan remains a Specially Serviced
Mortgage Loan or if such Mortgaged Property becomes an REO Property); provided
that such Special Servicer shall be entitled to reimbursement of the reasonable
and direct out-of-pocket expenses incurred by it in connection with each such
inspection as Servicing Advances and otherwise as contemplated by Section
3.05(a). Beginning in 2004, the applicable Master Servicer shall at its expense
perform or cause to be performed an inspection of the Mortgaged Property for
each Mortgage Loan (other than the Great Lakes Crossing Mortgaged Property) at
least once per calendar year on each Mortgage Loan, if the applicable Special
Servicer has not already done so during that period pursuant to the preceding
sentence. Each Master Servicer and each Special Servicer shall prepare a written
report (provided, that with respect to Co-op Mortgage Loans that are Performing
Mortgage Loans, such report shall be delivered to the Controlling Class
Representative in an electronic format, exclusive of photographs that are part
of such report, until such time as the NCBFSB Master Servicer or Co-op Special
Servicer, as the case may be, has established a website where such photographs
can be viewed, provided, further, however, that such report, complete with
photographs, shall be delivered to the Controlling Class Representative upon
request and, provided, further, that the NCBFSB Master Servicer shall use
commercially reasonable efforts to establish such websites with photographs on
or before December 31, 2003) of each such inspection performed by it or on its
behalf that sets forth in detail the condition of the subject Mortgaged Property
and that specifies the occurrence or existence of: (i) any sale, transfer or
abandonment of the subject Mortgaged Property of which such Master Servicer or
Special Servicer, as applicable, is aware, (ii) any change in the condition or
occupancy of the subject Mortgaged Property of which such Master Servicer or
Special Servicer, as applicable, is aware and that it considers, in accordance
with the Servicing Standard, material, or (iii) any waste committed on the
Mortgaged Property of which such Master Servicer or Special Servicer, as the
case may be, is aware and that it considers, in accordance with the Servicing
Standard, material. Each Master Servicer and each Special Servicer shall deliver
to the Controlling Class Representative (in accordance with the ARCap Naming
Convention for Electronic File Delivery) and, upon request, to the Trustee a
copy (or image in suitable electronic media) and, if the related Mortgage Loan
is the 622 Third Avenue Loan or the Washington Center Loan that is a Specially
Serviced Mortgage Loan, a copy to the 622 Third Avenue B Loan Holder and each
Washington Center Junior Holder, respectively, of each such written report
prepared by it (provided, that with respect to Co-op Mortgage Loans that are
Performing Mortgage Loans, such report shall be delivered to the Trustee and/or
Controlling Class Representative, as applicable, in an electronic format,
exclusive of photographs that are part of such report, until such time as the
NCBFSB Master Servicer or Co-op Special Servicer, as the case may be, has
established a website where such photographs can be viewed, provided, further,
however, that such report, complete with photographs, shall be delivered to the
Trustee and/or Controlling Class Representative and, if the related Mortgage
Loan is the 622 Third Avenue Loan or the Washington Center Loan that is a
Specially Serviced Mortgage Loan, a copy to the 622 Third Avenue B Loan Holder
and each Washington Center Junior Holder, respectively, upon request), in each
case within 30 days following the request (or, if later or if request is not
required, within 30 days following the later of completion of the related
inspection if the inspection is performed by the applicable Master Servicer or
Special Servicer, as applicable, or receipt of the related inspection report if
the inspection is performed by a third party). Upon request, the Trustee shall
request from such Master Servicer or Special Servicer, as applicable, and, to
the extent such items have been delivered to the Trustee upon written request by
such Master Servicer or Special Servicer, as applicable, deliver to each of the
Depositor, the related Mortgage Loan Seller, the Controlling Class
Representative, any Certificateholder and, if the related Mortgage Loan is the
622 Third Avenue Loan or the Washington Center Loan that is a Specially Serviced
Mortgage Loan, a copy to the 622 Third Avenue B Loan Holder and each Washington
Center Junior Holder, respectively, or, if the Trustee has in accordance with
Section 5.06(b) confirmed the Ownership Interest in Certificates held thereby,
any Certificate Owner, a copy (or image in suitable electronic media) of each
such written report prepared by a Master Servicer or a Special Servicer.

            (b) Commencing with respect to the calendar quarter ended June 30,
2003, the applicable Special Servicer, in the case of any Specially Serviced
Mortgage Loan, and the General Master Servicer, in the case of each Performing
Mortgage Loan that is a General Mortgage Loan and the NCBFSB Master Servicer, in
the case of Performing Mortgage Loans that are NCB Serviced Loans other than
Co-op Mortgage Loans, shall make reasonable efforts to collect promptly from
each related Borrower quarterly and annual operating statements, budgets and,
except with respect to residential cooperative properties, rent rolls of the
related Mortgaged Property, and quarterly and annual financial statements of
such Borrower, whether or not delivery of such items is required (or, in the
case of Co-op Mortgage Loans, only if delivery of such items is required)
pursuant to the terms of the related Mortgage Loan Documents. In addition, the
applicable Special Servicer shall cause quarterly and annual operating
statements, budgets and rent rolls to be regularly prepared in respect of each
REO Property and shall collect all such items promptly following their
preparation. Each Special Servicer shall deliver images in suitable electronic
media of all of the foregoing items so collected or obtained by it to the
applicable Master Servicer within 30 days of its receipt thereof. In the case of
each Performing Mortgage Loan that is a Co-op Mortgage Loan serviced by the
NCBFSB Master Servicer, such deliveries shall be limited to those required under
the applicable loan documents. Each Master Servicer shall deliver at least
quarterly all items required to be delivered to it by the applicable Special
Servicer pursuant to the second preceding sentence to the Controlling Class
Representative, in the case of the 622 Third Avenue Loan and the Washington
Center Loan, the 622 Third Avenue B Loan Holder and each Washington Center
Junior Holder, respectively, and the Trustee in an imaged format in accordance
with the ARCap Naming Convention for Electronic File Delivery.

            Each Master Servicer shall maintain a CMSA Operating Statement
Analysis Report with respect to each Mortgaged Property and REO Property related
to each Mortgage Loan for which it acts as Master Servicer. Within 60 days after
receipt by the applicable Master Servicer from the related Borrower or
otherwise, as to a Performing Mortgage Loan for which it acts as Master
Servicer, and within 30 days after receipt by the applicable Master Servicer
from the applicable Special Servicer, the Great Lakes Crossing Master Servicer
or otherwise, as to the Great Lakes Crossing Mortgage Loan, a Specially Serviced
Mortgage Loan or an REO Property for which it acts as Master Servicer, of any
annual operating statements and, except with respect to residential cooperative
properties, rent rolls with respect to any Mortgaged Property or REO Property,
such Master Servicer shall, based upon such operating statements or, except with
respect to residential cooperative properties, rent rolls, prepare (or, if
previously prepared, update) the CMSA Operating Statement Analysis Report for
the subject Mortgaged Property or REO Property. Each Master Servicer shall remit
in accordance with the ARCap Naming Convention for Electronic File Delivery of a
copy of each CMSA Operating Statement Analysis Report prepared or updated by it
(promptly following initial preparation and each update thereof), together with,
if so requested and not already provided pursuant to this Section 3.12(b), the
underlying operating statements and, except with respect to residential
cooperative properties, rent rolls, to the Controlling Class Representative, in
the case of the 622 Third Avenue Loan and the Washington Center Loan, the 622
Third Avenue B Loan Holder and each Washington Center Junior Holder,
respectively, the Trustee and the applicable Special Servicer. The Trustee
shall, upon request, request from the applicable Master Servicer (if necessary)
and, to the extent such items have been delivered to the Trustee by such Master
Servicer, deliver to any Certificateholder or, if the Trustee has in accordance
with Section 5.06(b) confirmed the Ownership Interest in the Certificates held
thereby, any Certificate Owner, a copy of the CMSA Operating Statement Analysis
(or update thereof) for any Mortgaged Property or REO Property and, if
requested, the related operating statement or, except with respect to
residential cooperative properties, rent rolls.

            Within 60 days (or, in the case of items received from a Special
Servicer, the Great Lakes Crossing Master Servicer, the Great Lakes Crossing
Special Servicer or otherwise with respect to the Great Lakes Crossing Mortgage
Loan, Specially Serviced Mortgage Loans and REO Properties, 30 days) after
receipt by a Master Servicer of any quarterly or annual operating statements
with respect to any Mortgaged Property or REO Property, such Master Servicer
shall prepare or update and forward to the Trustee, the applicable Special
Servicer, in the case of the 622 Third Avenue Loan and the Washington Center
Loan, the 622 Third Avenue B Loan Holder and each Washington Center Junior
Holder, respectively, and the Controlling Class Representative a CMSA NOI
Adjustment Worksheet using the same format and ARCap Naming Convention for
Electronic File Delivery as the CMSA Operating Statement Analysis Report for
such Mortgaged Property or REO Property, together with the related quarterly or
annual operating statements.

            If, with respect to any Mortgage Loan (other than a Specially
Serviced Mortgage Loan), the applicable Special Servicer has any questions for
the related Borrower based upon the information received by such Special
Servicer pursuant to Section 3.12(a) or 3.12(b), the applicable Master Servicer
shall, in this regard and without otherwise changing or modifying its duties
hereunder, reasonably cooperate with such Special Servicer in assisting such
Special Servicer to contact and solicit information from such Borrower.

            (c) Not later than 2:00 p.m. (New York City time) on the first
Business Day following each Determination Date, each Special Servicer shall
prepare and deliver or cause to be delivered to the applicable Master Servicer,
the Controlling Class Representative and shall contemporaneously provide a copy
of such materials as they relate to an A Loan to the B Loan Holder and the
Washington Center Junior Holders the following reports (or data files relating
to reports of the applicable Master Servicer) with respect to those Specially
Serviced Mortgage Loans serviced by such Special Servicer and any related REO
Properties as to which such Special Servicer is the applicable Special Servicer,
providing the CMSA Specially Serviced Loan File or other required information as
of such Determination Date which CMSA Specially Serviced Loan File the
applicable Master Servicer shall incorporate to produce: (i) a CMSA Property
File; and (ii) a CMSA Loan Periodic Update File (which, in each case, if
applicable, will identify each subject Mortgage Loan(s) by loan number and
property name). At or before 2:00 p.m. (New York City time) on the first
Business Day following each Determination Date, such Special Servicer shall
prepare and deliver or cause to be delivered to the applicable Master Servicer
the CMSA Specially Serviced Loan File or other related data fields reflected in
the reports reasonably requested with respect to the Specially Serviced Mortgage
Loans and REO Properties as to which such Special Servicer is the applicable
Special Servicer, providing the information required of such Special Servicer
pursuant to Section 3.12(e) as of such Determination Date. The applicable Master
Servicer shall prepare and deliver: (i) a CMSA Delinquent Loan Status Report;
(ii) a CMSA Comparative Financial Status Report; (iii) a CMSA Historical
Liquidation Report; (iv) a CMSA Historical Loan Modification Report; and (v) a
CMSA REO Status Report. In addition, each Special Servicer shall from time to
time provide the applicable Master Servicer with such information in such
Special Servicer's possession regarding any Specially Serviced Mortgage Loans
for which it acts as Special Servicer and related REO Properties as may be
requested by the applicable Master Servicer and is reasonably necessary for such
Master Servicer to prepare each report and any supplemental information required
to be provided by such Master Servicer to the Trustee.

            (d) Not later than 12:00 p.m. (New York City time) on the second
Business Day following each Determination Date, each Master Servicer shall
prepare (if and to the extent necessary) and deliver or cause to be delivered to
the Trustee (and shall contemporaneously provide a copy of such materials and
related reports as they relate to an A Loan to the B Loan Holder and the
Washington Center Junior Holders), in a computer-readable medium downloadable by
the Trustee (or, at the Trustee's written request, in a form reasonably
acceptable to the Trustee and such Master Servicer, including on a loan-by-loan
basis), each of the files and reports comprising the CMSA Investor Reporting
Package (excluding any CMSA Operating Statement Analysis Report, any CMSA NOI
Adjustment Worksheet, the CMSA Bond Level File, the CMSA Collateral Summary File
and the CMSA Loan Setup File), in each case providing the most recent
information with respect to the subject Mortgage Loans and REO Properties for
which it acts as Master Servicer as of the related Determination Date (and
which, in each case, if applicable, will identify each subject Mortgage Loan by
loan number and property name); provided that such Master Servicer shall not be
required to prepare and deliver any of the files and reports comprising the CMSA
Investor Reporting Package (other than the CMSA Loan Periodic Update File)
before the second Business Day following the second Determination Date following
the Closing Date.

            Notwithstanding the foregoing, because each Master Servicer will not
receive the Servicing Files until three (3) Business Days after the Closing Date
and will not have sufficient time to review and analyze such Servicing Files
before the initial Distribution Date, the parties agree that the CMSA Loan
Periodic Update File required to be delivered by each Master Servicer in July
2003 will be based solely upon information generated from actual collections
received by the applicable Master Servicer and from information the Depositor
delivers or causes to be delivered to the applicable Master Servicer (including
but not limited to information prepared by third party servicers of the subject
Mortgage Loans with respect to the period prior to the Closing Date). The
applicable Special Servicer shall from time to time (and, in any event, upon
request) provide such Master Servicer with such information in its possession
regarding the Specially Serviced Mortgage Loans for which it acts as Special
Servicer and the related REO Properties as may be necessary for such Master
Servicer to prepare each report and any supplemental information to be provided
by such Master Servicer to the Trustee.

            Notwithstanding the foregoing, the failure of a Master Servicer or
Special Servicer to disclose any information otherwise required to be disclosed
pursuant to this Section 3.12(d), Section 4.02(a) or Section 4.02(b) shall not
constitute a breach of this Section 3.12(d), Section 4.02(a) or Section 4.02(b)
to the extent such Master Servicer or such Special Servicer, as the case may be,
so fails because such disclosure, in the reasonable belief of such Master
Servicer or such Special Servicer, as the case may be, would violate any
applicable law or any provision of a Mortgage Loan Document prohibiting
disclosure of information with respect to the Mortgage Loans or the Mortgaged
Properties, would constitute a waiver of the attorney-client privilege on behalf
of the Trust or would otherwise materially harm the Trust Fund. A Master
Servicer or a Special Servicer may affix to any information provided by it any
disclaimer it deems appropriate in its reasonable discretion (without suggesting
liability on the part of any other party hereto).

            Any Master Servicer may, but is not required to, make any of the
reports or files comprising the CMSA Investor Reporting Package prepared by it
with respect to the Mortgage Loans and REO Properties as to which it is the
applicable Master Servicer, available each month on such Master Servicer's
internet website only with the use of a password, in which case such Master
Servicer shall provide such password to (i) the other parties to this Agreement,
who by their acceptance of such password shall be deemed to have agreed not to
disclose such password to any other Person, (ii) the Rating Agencies, the
Controlling Class Representative, the 622 Third Avenue B Loan Holder (with
respect to the 622 Third Avenue Loan) and each Washington Center Junior Holder
(with respect to the Washington Center Loan), and (iii) each Certificateholder
and Certificate Owner who requests such password, provided that any such
Certificateholder or Certificate Owner, as the case may be, has delivered a
certification substantially in the form of Exhibit K-1 to the Trustee (with a
copy to the applicable Master Servicer). In connection with providing access to
a Master Servicer's internet website, such Master Servicer may require
registration and the acceptance of a disclaimer and otherwise (subject to the
preceding sentence) adopt reasonable rules and procedures, which may include, to
the extent such Master Servicer deems necessary or appropriate, conditioning
access on execution of an agreement governing the availability, use and
disclosure of such information, and which may provide indemnification to such
Master Servicer for any liability or damage that may arise therefrom.

            Notwithstanding any other provision in this Agreement, the Master
Servicers, the Special Servicers and the Trustee shall deliver to the
Controlling Class Representative the reports (including the Payments Received
after Determination Date Report and the Mortgage Loans Delinquent Report) and
information set forth on Exhibit E-3 in the format and at the times set forth
therein.

            (e) Each Special Servicer shall deliver to the applicable Master
Servicer the reports set forth in Section 3.12(b) and Section 3.12(c), and the
applicable Master Servicer shall deliver to the Trustee the reports set forth in
Section 3.12(d), in an electronic format reasonably acceptable to such Special
Servicer, the applicable Master Servicer and the Trustee. Each Master Servicer
may, absent manifest error, conclusively rely on the reports to be provided by a
Special Servicer pursuant to Section 3.12(b) and Section 3.12(c). The Trustee
may, absent manifest error, conclusively rely on the reports to be provided by a
Master Servicer pursuant to Section 3.12(d). To the extent that any report to be
prepared and provided to the Trustee and/or the Controlling Class Representative
by a Master Servicer pursuant to Section 3.12(d) is dependent on information
from a Special Servicer (or, in the case of the Great Lakes Crossing Mortgage
Loan or any Great Lakes Crossing REO Property, from a party under a Great Lakes
Crossing Servicing Agreement), and such Special Servicer (or, if applicable,
such party under such Great Lakes Crossing Servicing Agreement) has not timely
provided such information to the Master Servicer, such Master Servicer shall on
a timely basis provide to the Trustee and/or the Controlling Class
Representative, as applicable, as complete a report as the information provided
by such Special Servicer (or, if applicable, by such party under such Great
Lakes Crossing Servicing Agreement) permits and shall promptly update and
provide to the Trustee and/or the Controlling Class Representative, as
applicable, a complete report when such Special Servicer (or, if applicable,
such party under such Great Lakes Crossing Servicing Agreement) provides the
Master Servicer with the requisite missing information; and no Master Servicer
shall be in breach hereunder for so providing an incomplete report under Section
3.12(d) under the foregoing circumstances. Furthermore, if any report to be
provided to the Trustee and/or the Controlling Class Representative by a Master
Servicer pursuant to Section 3.12(d) was to be prepared by a Special Servicer
(or, in the case of the Great Lakes Crossing Mortgage Loan or any Great Lakes
Crossing REO Property, by a party under a Great Lakes Crossing Servicing
Agreement) and delivered to such Master Servicer, such Master Servicer shall not
be in breach by reason of any delay in its delivery of such report to the
Trustee and/or the Controlling Class Representative, as applicable, by reason of
a delay on the part of the Special Servicer (or, if applicable, on the part of
such party under such Great Lakes Crossing Servicing Agreement) to deliver such
report to the Master Servicer; and the Master Servicer shall deliver as promptly
as reasonably practicable to the Trustee and/or the Controlling Class
Representative, as applicable, any such report that it receives from a Special
Servicer (or, if applicable, from such party under such Great Lakes Crossing
Servicing Agreement) after the requisite delivery date.

            (f) Notwithstanding the foregoing, however, the failure of a Master
Servicer or Special Servicer to disclose any information otherwise required to
be disclosed by this Section 3.12 shall not constitute a breach of this Section
3.12 to the extent such Master Servicer or Special Servicer so fails because
such disclosure, in the reasonable belief of such Master Servicer or Special
Servicer, as the case may be, would violate any applicable law or any provision
of a Mortgage Loan Document prohibiting disclosure of information with respect
to the Mortgage Loans or Mortgaged Properties or would constitute a waiver of
the attorney-client privilege on behalf of the Trust. The Master Servicers and
Special Servicers may disclose any such information or any additional
information to any Person so long as such disclosure is consistent with
applicable law, the related Mortgage Loan Documents and the Servicing Standard.
A Master Servicer or a Special Servicer may affix to any information provided by
it any disclaimer it deems appropriate in its reasonable discretion (without
suggesting liability on the part of any other party hereto).

            (g) On or before the Closing Date, the Depositor shall provide to
each Master Servicer and the Trustee, the initial data (as of the respective Due
Dates for the Original Mortgage Loans in June 2003 or the most recent earlier
date for which such data is available) contemplated by the CMSA Loan Setup File,
the CMSA Loan Periodic Update File, the CMSA Operating Statement Analysis Report
and the CMSA Property File.

            (h) If a Master Servicer or a Special Servicer is required to
deliver any statement, report or information under any provision of this
Agreement, such Master Servicer or Special Servicer, as the case may be, may
satisfy such obligation by (x) physically delivering a paper copy of such
statement, report or information, (y) delivering such statement, report or
information in a commonly used electronic format or (z) making such statement,
report or information available on such Master Servicer's internet website or
the Trustee's internet website, unless this Agreement expressly specifies a
particular method of delivery. Notwithstanding the foregoing, the Trustee may
request delivery in paper format of any statement, report or information
required to be delivered to the Trustee and clause (z) shall not apply to the
delivery of any information required to be delivered to the Trustee unless the
Trustee consents to such delivery.

            (i) The applicable Master Servicer shall, contemporaneously with any
related delivery to the Trustee or the applicable Special Servicer, as
applicable, provide any reports which contain information related to the related
Mortgaged Property or financial information regarding the Borrower to the B Loan
Holder and the Washington Center Junior Holders. The applicable Master Servicer
shall, with the reasonable cooperation of the other parties hereto, deliver to
each B Loan Holder and the Washington Center Junior Holders all documents,
statements, reports and information with respect to the related B Loan and the
Washington Center Junior Loans, respectively, and/or the related Mortgaged
Property as may be required under the related A/B Intercreditor Agreement.

            Section 3.13 Annual Statement as to Compliance

            Each Master Servicer and each Special Servicer shall deliver to the
Trustee, the Depositor, the Underwriters and the Controlling Class
Representative, on or before May 1 of each year, beginning in 2004, an Officer's
Certificate (the "Annual Performance Certification") stating, as to the signer
thereof, that (i) a review of the activities of such Master Servicer or such
Special Servicer, as the case may be, during the preceding calendar year and of
its performance under this Agreement has been made under such officer's
supervision, (ii) to the best of such officer's knowledge, based on such review,
such Master Servicer or such Special Servicer, as the case may be, has fulfilled
all of its obligations under this Agreement in all material respects throughout
such year (or, if there has been a default in the fulfillment of any such
obligation, specifying each such default known to such officer and the nature
and status thereof), and (iii) such Master Servicer or such Special Servicer, as
the case may be, has received no notice regarding the qualification, or
challenging the status, of the Upper-Tier REMIC, the Lower-Tier REMIC or the 622
Third Avenue Loan REMIC as a REMIC or the Grantor Trust as a grantor trust from
the IRS or any other governmental agency or body (or, if it has received any
such notice, specifying the details thereof); provided that each Master Servicer
and each Special Servicer shall be required to deliver its Annual Performance
Certification by March 15 in 2004 or any given year thereafter if it has
received written confirmation from the Trustee or the Depositor by January 31 of
that year that a Report on Form 10-K is required to be filed in respect of the
Trust for the preceding calendar year.

            Section 3.14 Reports by Independent Public Accountants

            On or before March 31 of each year, beginning in 2004, each Master
Servicer and each Special Servicer, at its expense, shall cause a firm of
independent public accountants that is a member of the American Institute of
Certified Public Accountants to furnish a statement (the "Annual Accountants'
Report") to the Trustee, the Depositor, the Underwriters and the Controlling
Class Representative, to the effect that such firm has examined the servicing
operations of such Master Servicer or such Special Servicer, as the case may be,
for the previous calendar year and that, on the basis of such examination,
conducted substantially in compliance with USAP, such firm confirms that such
Master Servicer or such Special Servicer, as the case may be, has complied
during such previous calendar year with the minimum servicing standards (to the
extent applicable to commercial and multifamily mortgage loans) identified in
USAP in all material respects, except for such significant exceptions or errors
in records that, in the opinion of such firm, USAP requires it to report;
provided that such Master Servicer and such Special Servicer shall each be
required to cause the delivery of its Annual Accountants' Report by March 15 in
2004 or any given year thereafter if it has received written confirmation from
the Trustee or the Depositor by January 31 of that year that a Report on Form
10-K is required to be filed in respect of the Trust for the preceding calendar
year. In rendering its report such firm may rely, as to matters relating to the
direct servicing of securitized commercial and multifamily mortgage loans by
sub-servicers, upon comparable reports of firms of independent certified public
accountants rendered on the basis of examinations conducted in accordance with
the same standards (rendered within one year of such report) with respect to
those sub-servicers.

            Each Master Servicer and each Special Servicer will reasonably
cooperate with the Depositor in providing any other form of accountants' reports
as may be required by the Commission in connection with the Commission's
issuance of a no-action letter relating to the Depositor's reporting
requirements in respect of the Trust pursuant to the Exchange Act, and the
reasonable additional costs of providing such other forms of accountants'
reports shall be borne by the Depositor.

            Section 3.15 Access to Certain Information

            (a) Each Master Servicer and each Special Servicer shall afford to
the Trustee, any Fiscal Agent, the Depositor, each Rating Agency and the
Controlling Class Representative and to the OTS, the FDIC and any other banking
or insurance regulatory authority that may exercise authority over any
Certificateholder or Certificate Owner, access to any records regarding the
Mortgage Loans and the servicing thereof within its control, except to the
extent it is prohibited from doing so by applicable law, the terms of the
related Mortgage Loan Documents or contract entered into prior to the Closing
Date or to the extent such information is subject to a privilege under
applicable law to be asserted on behalf of the Certificateholders. Such access
shall be afforded without charge but only upon reasonable prior written request
and during normal business hours at the offices of such Master Servicer or such
Special Servicer, as the case may be, designated by it. Each Master Servicer and
each Special Servicer may affix a reasonable disclaimer to any information
provided by it for which it is not the original source (without suggesting
liability on the part of any other party hereto). In connection with providing
access to such records to the Controlling Class Representative, the 622 Third
Avenue B Loan Holder, each Washington Center Junior Holder, each Master Servicer
and each Special Servicer may require registration (to the extent access is
provided via a Master Servicer's internet website) and the acceptance of a
reasonable and customary disclaimer and otherwise adopt reasonable rules and
procedures, which may include, to the extent a Master Servicer or Special
Servicer, as applicable, deems necessary or appropriate, conditioning access on
the execution and delivery of an agreement governing the availability, use and
disclosure of such information.

            (b) None of the Master Servicers or the Special Servicers shall be
liable for providing or disseminating information in accordance with the terms
of this Agreement.

            (c) Upon the request of the Controlling Class Representative made
not more frequently than once a month, or at such mutually acceptable time each
month as the Controlling Class Representative shall reasonably designate, each
of the Master Servicers and Special Servicers shall, without charge, make a
knowledgeable Servicing Officer available, at the option of such Controlling
Class Representative either by telephone or at the office of such Servicing
Officer, to answer questions from such Controlling Class Representative
regarding the performance and servicing of the Mortgage Loans and/or REO
Properties for which such Master Servicer or Special Servicer, as the case may
be, is responsible; provided, that if the Washington Center B Loan Holder is not
the then current Controlling Class Representative with respect to the Washington
Center Total Loan, then the Controlling Class Representative of the Washington
Center Total Loan shall provide the Washington Center B Loan Holder an
opportunity (by giving notice thereto) to join such telephone conference or such
conference at the office of such Servicing Officer.

            (d) Any Master Servicer may, in accordance with such reasonable
rules and procedures as it may adopt, also make available through its internet
website, or otherwise, any additional information relating to the Mortgage
Loans, the Mortgaged Properties or the Borrowers for review by the Depositor,
the Rating Agencies and any other Persons to whom the Master Servicers believe
such disclosure is appropriate, in each case except to the extent doing so is
prohibited by applicable law or by the related Mortgage Loan.

            (e) The Master Servicers and the Special Servicers may make
available the following items, in electronic form or otherwise, upon request
and, except in the case of a Rating Agency or a Controlling Class
Certificateholder, at the expense of the requesting party, to the Depositor, the
Trustee, the Rating Agencies, any Certificateholder, any Certificate Owner, the
622 Third Avenue B Loan Holder, each Washington Center Junior Holder, any
prospective transferee of a Certificate or an interest therein and any other
Persons to whom it believes such disclosure to be appropriate: (i) all financial
statements, occupancy information, rent rolls, retail sales information, average
daily room rates and similar information received by the Master Servicer or the
Special Servicer, as applicable, from each Borrower, (ii) the inspection reports
prepared by or on behalf of the Master Servicers or the Special Servicers, as
applicable, in connection with the property inspections pursuant to Section
3.12, (iii) any and all modifications, waivers and amendments of the terms of a
Mortgage Loan entered into by the Master Servicers or the Special Servicers, as
applicable, and (iv) any and all officer's certificates and other evidence
delivered to the Trustee and the Depositor to support the applicable Master
Servicer's determination that any Advance was, or if made would be, a
Nonrecoverable Advance; provided, however, that nothing in this Section 3.15(e)
shall be deemed or construed to otherwise limit the obligations of any Master
Servicer and any Special Servicer under this Agreement to deliver to any Person
any of the items set forth in clauses (i) through (iv) above.

            (f) Notwithstanding the obligations of each Master Servicer and each
Special Servicer set forth in Section 8.14, the Master Servicers and the Special
Servicers may withhold (other than with respect to items required to be
delivered hereunder to the Controlling Class Representative and with respect to
the Washington Center Loan, the Washington Center B Loan Holder (if not then the
Controlling Class Representative of the Washington Center Loan)) any information
not yet included in a Form 8-K filed with the Commission or otherwise made
publicly available with respect to which the Trustee, the Special Servicers or
the Master Servicers have determined that such withholding is appropriate.

            (g) Notwithstanding anything to the contrary in this Agreement, as a
condition to the Master Servicers or Special Servicers making any report or
information available upon request to any Person other than the parties hereto
and the Controlling Class Representative, 622 Third Avenue B Loan Holder or any
Washington Center Junior Holder, the Master Servicers and Special Servicers may
require that the recipient of such information acknowledge that the Master
Servicers and Special Servicers may contemporaneously provide such information
to the Depositor, the Trustee, the Underwriters, any Rating Agency, the
Certificateholders and/or the Certificate Owners. Each Master Servicer and
Special Servicer may condition such disclosure upon the recipient delivering a
certification substantially in the form of Exhibit K-1 to the Trustee (with a
copy to the applicable Master Servicer) or otherwise entering into a reasonable
and customary confidentiality agreement reasonably acceptable to such servicer
regarding such disclosure to it. In connection with providing access to its
internet website, any Master Servicer may require registration and the
acceptance of a disclaimer and otherwise (subject to the preceding sentence)
adopt reasonable rules and procedures, which may include, to the extent it deems
necessary or appropriate, conditioning access on execution of an agreement
governing the availability, use and disclosure of such information, and which
may provide indemnification to the applicable Master Servicer for any liability
or damage that may arise therefrom. Any transmittal of information by the Master
Servicers or Special Servicers to any Person other than the Trustee, the Rating
Agencies or the Depositor shall be accompanied by a letter from each Master
Servicer or Special Servicer containing the following provision:

            "By receiving the information set forth herein, you hereby
            acknowledge and agree that the United States securities
            laws restrict any person who possesses material,
            non-public information regarding the Trust which issued
            Credit Suisse First Boston Mortgage Securities Corp.,
            Commercial Mortgage Pass-Through Certificates, Series
            2003-C3 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 or prospective purchaser of such
            Certificates or beneficial interest therein."

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

            Section 3.16 Title to REO Property; REO Account

            (a) If title to any REO Property (other than the Great Lakes
Crossing Mortgaged Property) is acquired, the deed or certificate of sale shall
be issued to the Trustee or its nominee, on behalf of the Certificateholders
(and on behalf of the related B Loan Holder and the Washington Center Junior
Holders if such REO Property is related to an A/B Loan Pair) or, subject to
Section 3.09(b), to a single member limited liability company of which the Trust
is the sole member, which limited liability company is formed or caused to be
formed by the applicable Special Servicer at the expense of the Trust for the
purpose of taking title to one or more REO Properties (other than the Great
Lakes Crossing Mortgaged Property) pursuant to this Agreement. The limited
liability company shall be a manager-managed limited liability company, with the
Special Servicer to serve as the initial manager to manage the property of the
limited liability company, including any applicable REO Property, in accordance
with the terms of this Agreement as if such property was held directly in the
name of the Trust or Trustee under this Agreement (and for the benefit of the
related B Loan Holder and the Washington Center Junior Holders if such REO
Property is related to an A/B Loan Pair). The applicable Special Servicer, on
behalf of the Trust (and for the benefit of the related B Loan Holder and the
Washington Center Junior Holders if such REO Property is related to an A/B Loan
Pair), shall sell any REO Property in accordance with Section 3.18 by the end of
the third calendar year (or, in the case of a "qualified healthcare property"
within the meaning of Section 856(c)(6) of the Code, the end of the second
calendar year) following the year in which the Trust acquires ownership of such
REO Property for purposes of Section 860G(a)(8) of the Code, unless such Special
Servicer either (i) applies, more than 60 days prior to the expiration of such
liquidation period, and is granted an extension of time (an "REO Extension") by
the IRS to sell such REO Property or (ii) obtains for the Trustee an Opinion of
Counsel, addressed to the Trustee, to the effect that the holding by the Trust
of such REO Property subsequent to the end of the third calendar year (or, in
the case of a "qualified healthcare property" within the meaning of Section
856(c)(6) of the Code, the end of the second calendar year) following the year
in which such acquisition occurred will not result in an Adverse REMIC Event
with respect to the Upper-Tier REMIC, the Lower-Tier REMIC or the 622 Third
Avenue Loan REMIC or an Adverse Grantor Trust Event with respect to the Grantor
Trust. Regardless of whether the applicable Special Servicer applies for or is
granted the REO Extension contemplated by clause (i) of the immediately
preceding sentence or obtains the Opinion of Counsel referred to in clause (ii)
of such sentence, the applicable Special Servicer shall act in accordance with
the Servicing Standard to liquidate the subject REO Property on a timely basis.
If the applicable Special Servicer is granted such REO Extension or obtains such
Opinion of Counsel with respect to any REO Property, such Special Servicer shall
(i) promptly forward a copy of such REO Extension or Opinion of Counsel to the
Trustee, and (ii) sell such REO Property within such extended period as is
permitted by such REO Extension or contemplated by such Opinion of Counsel, as
the case may be. Any expense incurred by a Special Servicer in connection with
its applying for and being granted the REO Extension contemplated by clause (i)
of the third preceding sentence or its obtaining the Opinion of Counsel (which
Opinion of Counsel, if the subject REO Property is the Mortgaged Property that
secures the 622 Third Avenue Loan or the Washington Center Loan, shall not be
payable by or from amounts otherwise distributable to the related B Loan or any
Washington Center Junior Holder) contemplated by clause (ii) of the third
preceding sentence, and for the creation of and the operating of a limited
liability company, shall be covered by, and be reimbursable as, a Servicing
Advance.

            (b) Each Special Servicer shall segregate and hold all funds
collected and received by it in connection with any REO Property separate and
apart from its own funds and general assets. If title to any REO Property is
acquired by or on behalf of the Trust, then the applicable Special Servicer
shall establish and maintain one or more accounts (collectively, the "REO
Account"), to be held on behalf of the Trustee (as holder of the Uncertificated
Lower-Tier Interests and the 622 Third Avenue Loan REMIC Regular Interests) in
trust for the benefit of the Certificateholders (and on behalf of the related B
Loan Holder and the Washington Center Junior Loans if such REO Property is
related to an A/B Loan Pair), for the retention of revenues and other proceeds
derived from each REO Property. Each account that constitutes an 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 following receipt, all
REO Revenues, Insurance Proceeds and Liquidation Proceeds received in respect of
the REO Property. Funds in the REO Account may be invested in Permitted
Investments in accordance with Section 3.06. The Special Servicer shall be
entitled to make withdrawals from the REO Account to pay itself, as Additional
Special Servicing Compensation, interest and investment income earned in respect
of amounts held in the REO Account as provided in Section 3.06(b) (but only to
the extent of the Net Investment Earnings, if any, with respect to the REO
Account for any Collection Period). The Special Servicer shall give notice to
the other parties hereto of the location of the REO Account when first
established and of the new location of its 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. Five (5) Business Days prior to
each Determination Date, and again on the first Business Day following such
Determination Date, the applicable Special Servicer shall withdraw from its REO
Account and deposit into the applicable Master Servicer's Collection Account
(or, if the subject REO Property relates to an A/B Loan Pair, into the related
A/B Loan Pair Custodial Account), or deliver to the applicable Master Servicer
for deposit into such Collection Account (or, if the subject REO Property
relates to an A/B Loan Pair, into the related A/B Loan Pair Custodial Account)
the aggregate of all amounts received in respect of each REO Property during the
Collection Period ending on such Determination Date that are then on deposit in
such REO Account, net of any withdrawals made out of such amounts pursuant to
the preceding sentence; provided that, in the case of each REO Property, the
applicable Special Servicer may retain in the REO Account such portion of such
proceeds and collections as may be necessary to maintain a reserve of sufficient
funds for the proper operation, management, leasing, maintenance and disposition
of the related REO Property (including the creation of a reasonable reserve for
repairs, replacements, necessary capital improvements and other related
expenses), such reserve not to exceed an amount sufficient to cover such items
reasonably expected to be incurred during the following 12-month period.

            (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
3.16(c).

            (e) The REO Property and the related REO Account with respect to the
622 Third Avenue Loan REMIC shall be treated as assets of such REMIC for all
purposes of this Agreement.

            Section 3.17 Management of REO Property

            (a) Prior to the acquisition of title to any Mortgaged Property
securing a defaulted Mortgage Loan, the applicable Special Servicer shall review
the operation of such Mortgaged Property and determine the nature of the income
that would be derived from such property if it were acquired by the Trust. If
the applicable Special Servicer determines from such review that:

            (i) None of the income from Directly Operating such Mortgaged
      Property would be subject to tax as "net income from foreclosure property"
      within the meaning of the REMIC Provisions (such tax referred to herein as
      an "REO Tax"), then such Mortgaged Property may be Directly Operated by
      the applicable Special Servicer as REO Property (other than the
      performance of activities for which an Independent Contractor is
      required);

            (ii) Directly Operating such Mortgaged Property as an REO Property
      could result in income from such property that would be subject to an REO
      Tax, but that a lease of such property to another party to operate such
      property, or the performance of some services by an Independent Contractor
      with respect to such property, or another method of operating such
      property would not result in income subject to an REO Tax, then such
      Special Servicer may (provided that in the judgment of such Special
      Servicer, exercised in accordance with the Servicing Standard, it is
      commercially reasonable) so lease or otherwise operate such REO Property;
      or

            (iii) It is reasonable to believe that Directly Operating such
      property as REO Property could result in income subject to an REO Tax and
      that no commercially reasonable means exists to operate such property as
      REO Property without the Trust incurring or possibly incurring an REO Tax
      on income from such property, such Special Servicer shall deliver to the
      Trustee and the Controlling Class Representative, in writing, a proposed
      plan (the "Proposed Plan") to manage such property as REO Property. Such
      plan shall include potential sources of income and good faith estimates of
      the amount of income from each such source. Within a reasonable period of
      time after receipt of such plan, the Trustee shall consult with such
      Special Servicer and shall advise such Special Servicer of the Trust's
      federal income tax reporting position with respect to the various sources
      of income that the Trust would derive under the Proposed Plan. In
      addition, the Trustee shall (to the maximum extent reasonably possible)
      advise such Special Servicer of the estimated amount of taxes that the
      Trust would be required to pay with respect to each such source of income.
      After receiving the information described in the two preceding sentences
      from the Trustee, such Special Servicer shall either (A) implement the
      Proposed Plan (after acquiring the respective Mortgaged Property as REO
      Property) or (B) manage and operate such property in a manner that would
      not result in the imposition of an REO Tax on the income derived from such
      property.

            Subject to Section 3.17(b), the applicable Special Servicer's
decision as to how each REO Property shall be managed and operated shall be in
accordance with the Servicing Standard. Neither the Special Servicers nor the
Trustee shall be liable to the Certificateholders, the Trust, the other parties
hereto or each other for errors in judgment made in good faith in the exercise
of their discretion while performing their respective responsibilities under
this Section 3.17(a) with respect to any REO Property. Nothing in this Section
3.17(a) is intended to prevent the sale of any REO Property pursuant to the
terms and subject to the conditions of Section 3.18.

            (b) If title to any REO Property (other than the Great Lakes
Crossing Mortgaged Property) is acquired, the applicable Special Servicer shall
manage, conserve, protect and operate such REO Property for the benefit of the
Certificateholders (and for the benefit of the holder of the B Loan Holder and
the Washington Center Junior Holders if such REO Property is related to an A/B
Loan Pair) solely for the purpose of its prompt disposition and sale in
accordance with Section 3.18, 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, except as contemplated by Section 3.17(a), result in
the receipt by the Upper-Tier REMIC, Lower-Tier REMIC or 622 Third Avenue Loan
REMIC of any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code, in an Adverse REMIC Event with respect to the
Upper-Tier REMIC, the Lower-Tier REMIC or the 622 Third Avenue Loan REMIC or in
an Adverse Grantor Trust Event with respect to the Grantor Trust. Except as
contemplated by Section 3.17(a), the applicable Special Servicer shall not enter
into any lease, contract or other agreement with respect to any REO Property
that causes the Trust to receive, and (unless required to do so under any lease,
contract or agreement to which the applicable Special Servicer or the Trust may
become a party or successor to a party due to a foreclosure, deed-in-lieu of
foreclosure or other similar exercise of a creditor's rights or remedies with
respect to the related Mortgage Loan) shall not, with respect to any REO
Property, cause or allow the Trust to receive, any "net income from foreclosure
property" that is subject to taxation under the REMIC Provisions. Subject to the
foregoing, however, the applicable Special Servicer shall have full power and
authority to do any and all things in connection with the administration of any
REO Property, as are consistent with the Servicing Standard and, consistent
therewith, shall withdraw from its REO Account, to the extent of amounts on
deposit therein with respect to such REO Property, funds necessary for the
proper operation, management, maintenance and disposition of such REO Property,
including:

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

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

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

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

            To the extent that amounts on deposit in the applicable Special
Servicer's REO Account with respect to any REO Property are insufficient for the
purposes contemplated by the preceding sentence with respect to such REO
Property, the applicable Master Servicer shall, at the direction of the
applicable Special Servicer pursuant to Section 3.19(b), make a Servicing
Advance of such amounts as are necessary for such purposes unless such Master
Servicer or Special Servicer determines, in its reasonable judgment, that such
advances would, if made, be Nonrecoverable Servicing Advances; provided,
however, that such Master Servicer may in its sole discretion make any such
Servicing Advance without regard to recoverability if it is a necessary fee or
expense incurred in connection with the defense or prosecution of legal
proceedings.

            Notwithstanding the foregoing, the 622 Third Avenue B Loan Holder or
the Washington Center Junior Holders shall be not required to reimburse the
Trust Fund or any other Person for a payment of any REMIC taxes or Advances
therefor or interest accrued thereon at the Advance Rate or for deficits in
other items of disbursement or income resulting from the use of funds for
payment of REMIC taxes or for any REMIC related opinions or REMIC administration
fees.

            (c) The applicable Special Servicer may, and if required to maintain
the status of the REO Property as "foreclosure property" pursuant to Section
860G(a)(8) of the Code, shall contract with any Independent Contractor for the
operation and management of any REO Property, provided that:

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

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

            (iii) any such contract shall require, or shall be administered to
      require, that the Independent Contractor, in a timely manner, (A) pay all
      costs and expenses incurred in connection with the operation and
      management of such REO Property, including those listed in Section 3.17(b)
      above, and (B) remit all related revenues collected (net of its fees and
      such costs and expenses) to such 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 such Special Servicer of any of its duties and
      obligations hereunder with respect to the operation and management of any
      such REO Property; and

            (v) such 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.

            Each 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 such Special Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. To the extent the costs of any contract with any
Independent Contractor for the operation and management of any REO Property are
greater that the revenues available from such property, such excess costs shall
be covered by, and be reimbursable to the applicable Master Servicer as, a
Servicing Advance.

            Section 3.18 Fair Value Option; Sale of REO Properties

            (a) The parties hereto may sell or purchase, or permit the sale or
purchase of, a Mortgage 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 and Section 9.01 of this Agreement; the
Mortgage Loan Purchase Agreements; the Column Performance Guarantee; and the
related Mortgage Loan Documents and/or, in the case of an A Loan, the related
A/B Intercreditor Agreement.

            (b) If any Mortgage Loan becomes a Specially Designated Defaulted
Mortgage Loan, then the applicable Special Servicer shall so notify, in writing,
the Trustee, the Controlling Class Representative, the applicable Master
Servicer, the Holder(s) of the Controlling Class, the B Loan Holders (with
respect to the related A Loan) and the Washington Center Junior Holders (with
respect to the Washington Center Loan). In addition, such Special Servicer shall
determine (in accordance with the Servicing Standard, taking into account the
considerations contemplated by the following paragraph, but without regard to
the Purchase Option provided for in Section 3.18(c) below), and report to the
Trustee, the applicable Master Servicer, the Controlling Class Representative
(and with respect to the 622 Third Avenue Loan and the Washington Center Loan,
the Washington Center Junior Holders and the 622 Third Avenue B Loan Holder) and
the Holder(s) of the Controlling Class, the Fair Value of such Mortgage Loan.
The applicable Special Servicer's determination of the Fair Value of any
Specially Designated Defaulted Mortgage Loan shall be made as soon as reasonably
practicable, but in no event later than 30 days after the applicable Special
Servicer receives the requisite Appraisal or any other third-party reports that
it deems necessary to make the determination. If at any time the applicable
Special Servicer becomes aware of any circumstances or conditions that have
occurred or arisen with respect to any Specially Designated Defaulted Mortgage
Loan or the related Mortgaged Property subsequent to, and that would, in such
Special Servicer's reasonable judgment, materially affect, such Special
Servicer's most recent Fair Value determination with respect to such Specially
Designated Defaulted Mortgage Loan, then the applicable Special Servicer shall
redetermine (in a manner as is permitted above, but taking into account any new
circumstances or conditions known to the applicable Special Servicer), and
report to the Trustee, the Controlling Class Representative and the applicable
Master Servicer (and the Trustee shall, in turn, report to the Holder(s) of the
Controlling Class), the updated Fair Value of the subject Specially Designated
Defaulted Mortgage Loan. In addition, if the applicable Special Servicer has not
accepted a bid at the Fair Value of the Mortgage Loan, as most recently
determined by the applicable Special Servicer, prior to the expiration of 90
days from such determination, and thereafter the applicable Special Servicer
receives a bid at such Fair Value or a request from a holder of the Purchase
Option for an updated determination of the Fair Value of the Mortgage Loan, the
applicable Special Servicer shall redetermine (in the same manner as provided
above, but taking into account any new circumstances or conditions known to such
Special Servicer), and report to the Trustee, the Controlling Class
Representative and the applicable Master Servicer (and the Trustee shall, in
turn, report to the Holder(s) of the Controlling Class), the updated Fair Value
of the subject Specially Designated Defaulted Mortgage Loan; provided, however,
that the applicable Special Servicer may rely on the existing third-party
information if in its reasonable judgment it determines such reliance to be
reasonable.

            In determining the Fair Value of any Specially Designated Defaulted
Mortgage Loan, the applicable Special Servicer shall take into account, among
other factors, the period and amount of the delinquency on such Mortgage Loan,
the occupancy level and physical condition of the related Mortgaged Property,
the state of the local economy in the area where the related Mortgaged Property
is located, and the time and expense associated with and the expected recovery
from a purchaser's foreclosing on the related Mortgaged Property or working out
such Mortgage Loan. In addition, the applicable Special Servicer shall refer to
all relevant information contained in the Servicing File, shall take into
account the most recent Appraisal obtained or conducted with respect to the
related Mortgaged Property in the preceding 12-month period in accordance with
this Agreement and shall not determine the Fair Value of any Specially
Designated Defaulted Mortgage Loan without such an Appraisal; provided that such
Special Servicer shall take account of any change in the circumstances regarding
or the condition of the related Mortgaged Property known to such Special
Servicer that has occurred or arisen subsequent to, and that would materially
affect the value of the related Mortgaged Property reflected in, such Appraisal.
Furthermore, the applicable Special Servicer shall consider any offers from
third parties desiring to purchase the Specially Designated Defaulted Mortgage
Loan, available objective third-party information obtained from generally
available sources, as well as information obtained from vendors providing real
estate services to such Special Servicer, concerning the market for distressed
real estate loans and the real estate market for the subject property type in
the area where the related Mortgaged Property is located. A Special Servicer
may, to the extent it is reasonable to do so, conclusively rely on any opinions
or reports of Independent third parties in making such determination. All
reasonable costs and expenses incurred by a Special Servicer pursuant to this
Section 3.18(b) shall constitute, and be reimbursable to the applicable Master
Servicer as, Servicing Advances. The other parties to this Agreement shall
cooperate with all reasonable requests for information made by a Special
Servicer in order to allow such Special Servicer to perform its duties pursuant
to this Section 3.18(b).

            (c) The Majority Controlling Class Certificateholder(s) (but, with
respect to the 622 Third Avenue Loan, not a Controlling Class Representative of
the Class 622 Participation Certificates, but the Controlling Class
Representative of the Regular Certificates) or any assignee thereof may, at its
or their option, purchase from the Trust any Specially Designated Defaulted
Mortgage Loan (such option, the "Purchase Option"), at a cash price (the "Option
Price") equal to the Fair Value of such Mortgage Loan (as most recently
determined by the applicable Special Servicer and reported to the Trustee, the
Controlling Class Representative and the applicable Master Servicer as provided
in Section 3.18(b) above) or, if no such Fair Value has yet been established as
provided in Section 3.18(b) above or if the applicable Special Servicer is in
the process of redetermining such Fair Value because of a change in
circumstances, equal to the Purchase Price; provided, that with respect to an A
Loan, the option holder's rights under this Section 3.18(c) are subject to the
rights of the related B Loan Holder or any Washington Center Junior Holder or
the Washington Center Loan mezzanine holder to purchase the related A Loan
pursuant to the terms of the related A/B Intercreditor Agreement at any time
permissible under the terms of the related A/B Intercreditor Agreement,
regardless of any notice of intent to exercise the Purchase Option or tender of
the Option Price by any option holder hereunder; provided, further, that:

            (i) the Purchase Option with respect to any Specially Designated
      Defaulted Mortgage Loan will remain in effect only for the period (the
      "Option Period") that commences on the date that such Mortgage Loan first
      becomes a Specially Designated Defaulted Mortgage Loan and ends on the
      earliest of (A) the date on which such Mortgage Loan becomes a Corrected
      Mortgage Loan or otherwise ceases to be a Specially Designated Defaulted
      Mortgage Loan and (B) the date on which a Liquidation Event occurs with
      respect to such Mortgage Loan or the related Mortgaged Property becomes an
      REO Property; provided, that the option with respect to an A Loan shall
      terminate upon the purchase of the A Loan by the related B Loan Holder or
      any Washington Center Junior Holder or the Washington Center Loan
      mezzanine holder pursuant to the related A/B Intercreditor Agreement.

            (ii) the Purchase Option with respect to any Specially Designated
      Defaulted Mortgage Loan will be assignable by the Majority Controlling
      Class Certificateholder(s) during the Option Period to any third party
      (provided that the parties hereto are notified in writing of the
      assignment) pursuant to an assignment in the form attached hereto as
      Exhibit Q;

            (iii) if the Purchase Option with respect to any Specially
      Designated Defaulted Mortgage Loan is not exercised by the Majority
      Controlling Class Certificateholder(s) or any assignee thereof within 60
      days after the Fair Value of such Mortgage Loan has initially been
      established as provided in Section 3.18(b) above, then the Majority
      Controlling Class Certificateholder(s) shall automatically be deemed to
      have assigned (without the need for any written assignment or other
      agreement or notice to any Person) such Purchase Option, for a 30-day
      period only, to the applicable Special Servicer;

            (iv) during the 30-day period following the assignment to it of the
      Purchase Option with respect to any Specially Designated Defaulted
      Mortgage Loan, the applicable Special Servicer shall be entitled to
      exercise such Purchase Option (subject to the same terms and conditions as
      the option holder) or to assign such Purchase Option to any third party
      pursuant to an assignment in the form of Exhibit Q (provided that the
      other parties hereto are notified in writing of the assignment);

            (v) if the Purchase Option with respect to any Specially Designated
      Defaulted Mortgage Loan is not exercised by the applicable Special
      Servicer or its assignee within the 30-day period following the assignment
      of such Purchase Option to the applicable Special Servicer as contemplated
      by clause (iii) above, then such Purchase Option will automatically revert
      to the Majority Controlling Class Certificateholder(s); and

            (vi) prior to any exercise of the Purchase Option with respect to
      any Specially Designated Defaulted Mortgage Loan by the applicable Special
      Servicer or any Affiliate or assignee thereof, subject to the following
      paragraph, the General Master Servicer shall confirm and report to the
      Trustee and such Special Servicer (or, if the General Master Servicer and
      such Special Servicer are the same Person or Affiliates, the Trustee, upon
      reasonable notice, shall confirm and report to such Special Servicer) that
      the applicable Special Servicer's determination of the Fair Value of such
      Mortgage Loan is consistent with or greater than what the General Master
      Servicer (or, if applicable, the Trustee) considers to be the Fair Value
      of such Mortgage Loan; provided that the applicable Special Servicer may
      revise any such Fair Value determination that is rejected by the General
      Master Servicer (or, if applicable, the Trustee).

            Notwithstanding anything contained in clause (vi) of the preceding
paragraph to the contrary, if the General Master Servicer or the Trustee is
required to confirm or reject such Special Servicer's Fair Value determination
as contemplated by such clause (vi), either such party may (at its option)
designate an Independent third party expert in real estate or commercial
mortgage loan matters with at least 5 years' experience in valuing or investing
in loans similar to the subject Specially Designated Defaulted Mortgage Loan,
that has been selected with reasonable care by the General Master Servicer (or,
if applicable, the Trustee) to confirm that such Special Servicer's Fair Value
determination as contemplated by such clause (vi) is consistent with or greater
than what the Independent third party considers to be the Fair Value of such
Mortgage Loan. In the event that the General Master Servicer or the Trustee, as
the case may be, designates such a third party to make such determination, the
General Master Servicer or the Trustee, as applicable, shall be entitled to rely
upon such third party's determination. The reasonable costs of all appraisals,
inspection reports and third-party opinions of value, incurred by the General
Master Servicer, the Trustee or any such third party pursuant to this paragraph
or clause (vi) of the preceding paragraph shall be advanced by the General
Master Servicer or the Trustee, as applicable, and shall constitute, and be
reimbursable as, Servicing Advances.

            In addition, the General Master Servicer or the Trustee, as the case
may be, shall be entitled to receive out of the Collection Account a $2,500 fee
for the initial confirmation of the applicable Special Servicer's Fair Value
Determination (but no fee for any subsequent confirmation of such Special
Servicer's Fair Value Determination) that is made by it with respect to any
Specially Designated Defaulted Mortgage Loan, in accordance with this Section
3.18(c).

            Any party entitled to do so may exercise the Purchase Option with
respect to any Specially Designated Defaulted Mortgage Loan by providing to the
Trustee, the applicable Master Servicer and the applicable Special Servicer--

            (i) written notice of its intention to purchase such Mortgage Loan
      at the Option Price; and

            (ii) if such party is the assignee of the applicable Special
      Servicer or the Majority Controlling Class Certificateholder(s), evidence
      of its right to exercise such Purchase Option.

The actual purchase of such Specially Designated Defaulted Mortgage Loan shall
occur (by delivery of cash in the amount of the applicable Option Price to the
applicable Special Servicer for deposit in the applicable Master Servicer's
Collection Account) no later than 10 days after the later of (i) such exercise
of the Purchase Option with respect to such Mortgage Loan and (ii) if
applicable, the confirmation of such Special Servicer's Fair Value determination
with respect to such Mortgage Loan in accordance with clause (vi) of the first
paragraph of this Section 3.18(c) and/or in accordance with the second paragraph
of this Section 3.18(c). If the Purchase Option is exercised by a third-party
assignee, the purchase of the Specially Designated Defaulted Mortgage Loan may
be made pursuant to a mortgage loan purchase agreement in form and substance
satisfactory to the applicable Special Servicer and the Majority Controlling
Class Certificateholder, provided, that such agreement shall provide that the
sale of the Specially Designated Defaulted Mortgage Loan shall be final and
without representation or warranty other than customary representations as to
title similar to those given in connection with the sale of real property. If
the Purchase Option is exercised by a third-party assignee and such third-party
assignee fails to complete such purchase within the time period provided above,
the Purchase Option shall not be deemed extinguished but shall revert back to
the assignor of such Purchase Option as if the Purchase Option had not been
exercised. The applicable Special Servicer may enforce any remedies it may have
against the assignee for failure to complete such purchase.

            Notwithstanding the Purchase Option provided for in this Section
3.18(c) and subject to Sections 3.23, 3.24, and 3.27, the applicable Special
Servicer shall proceed in respect of any Specially Designated Defaulted Mortgage
Loan in accordance with Section 3.09 and/or Section 3.20, without regard to such
Purchase Option.

            (d) The applicable Special Servicer shall use its reasonable
efforts, consistent with the Servicing Standard, to solicit cash bids for each
REO Property in such manner as will be reasonably likely to realize a fair price
(determined pursuant to Section 3.18(e) below) for any REO Property within a
customary and normal time frame for the sale of comparable properties (and, in
any event, within the time period provided for by Section 3.16(a)). Such Special
Servicer shall accept the first (and, if multiple cash bids are received by a
specified bid date, the highest) cash bid received from any Person that
constitutes a fair price (determined pursuant to Section 3.18(e) below) for such
REO Property. If such Special Servicer reasonably believes that it will be
unable to realize a fair price (determined pursuant to Section 3.18(e) below)
with respect to any REO Property within the time constraints imposed by Section
3.16(a), then such Special Servicer shall, consistent with the Servicing
Standard, dispose of such REO Property upon such terms and conditions as it
shall deem necessary and desirable to maximize the recovery thereon under the
circumstances.

            The applicable Special Servicer shall give the Trustee, the
applicable Master Servicer and the Controlling Class Representative not less
than five (5) Business Days' prior written notice of its intention to sell any
REO Property pursuant to this Section 3.18(d). No Interested Person shall be
obligated to submit a bid to purchase any 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 REO Property
pursuant hereto.

            (e) Whether any cash bid constitutes a fair price for any REO
Property for purposes of Section 3.18(d) shall be determined by the applicable
Special Servicer or, if such cash bid is from an Interested Person, by the
Trustee. In determining whether any bid received from an Interested Person
represents a fair price for any REO Property, the Trustee shall be supplied with
and shall be entitled to rely on the most recent Appraisal in the related
Servicing File conducted in accordance with this Agreement within the preceding
12-month period (or, in the absence of any such Appraisal or if there has been a
material change at the subject property since any such Appraisal, on a new
Appraisal to be obtained by the applicable Special Servicer, the cost of which
shall be covered by, and be reimbursable to the applicable Master Servicer as, a
Servicing Advance). The appraiser conducting any such new Appraisal shall be a
Qualified Appraiser that is (i) selected by the applicable Special Servicer if
neither such Special Servicer nor any Affiliate thereof is bidding with respect
to the subject REO Property and (ii) selected by the Trustee if either such
Special Servicer or any Affiliate thereof is so bidding. If any Interested
Person is among those bidding with respect to any REO Property, such Special
Servicer shall require that all bids be submitted to it (or, if such Special
Servicer is bidding, be submitted to the Trustee) in writing and be accompanied
by a refundable deposit of cash in an amount equal to 5% of the bid amount. In
determining whether any bid from a Person other than an Interested Person
constitutes a fair price for any REO Property, such Special Servicer shall take
into account the results of any Appraisal or updated Appraisal that it or the
applicable Master Servicer may have obtained in accordance with this Agreement
within the prior twelve (12) months, as well as, among other factors, the
occupancy level and physical condition of the REO Property, the state of the
then current local economy and commercial real estate market where the REO
Property is located and the obligation to dispose of any REO Property within a
customary and normal time frame for the sale of comparable properties (and, in
any event, within the time period specified in Section 3.16(a)). The Purchase
Price for any REO Property shall in all cases constitute a fair price.
Notwithstanding the other provisions of this Section 3.18, no cash bid from the
applicable Special Servicer or any Affiliate thereof shall constitute a fair
price for any REO Property unless such bid is the highest cash bid received and
at least two Independent bids (not including the bid of such Special Servicer or
any Affiliate) have been received. In the event the bid of the applicable
Special Servicer or any Affiliate thereof is the only bid received or is the
higher of only two bids received, then additional bids shall be solicited. If an
additional bid or bids, as the case may be, are received for any REO Property
and the original bid of such Special Servicer or any Affiliate thereof is the
highest of all bids received, then the bid of such Special Servicer or such
Affiliate shall be accepted, provided that the Trustee has otherwise determined,
as provided above in this Section 3.18(e), that such bid constitutes a fair
price for the subject REO Property. Any bid by the applicable Special Servicer
for any REO Property shall be unconditional; and, if accepted, the subject REO
Property shall be transferred to such Special Servicer without recourse,
representation or warranty other than customary representations as to title
given in connection with the sale of a real property.

            (f) Subject to Sections 3.18(a) through 3.18(e) above, the
applicable Special Servicer shall act on behalf of the Trustee in negotiating
with Independent third parties in connection with the sale of any REO Property
and taking any other action necessary or appropriate in connection with the sale
of any Specially Designated Defaulted Mortgage Loan or REO Property, and the
collection of all amounts payable in connection therewith. In connection with
the sale of any REO Property, the applicable Special Servicer may charge
prospective bidders, and may retain, fees that approximate such Special
Servicer's actual costs in the preparation and delivery of information
pertaining to such sales or evaluating bids without obligation to deposit such
amounts into a Collection Account. Any sale of a Specially Designated Defaulted
Mortgage Loan or any REO Property shall be final and without recourse to the
Trustee or the Trust, and if such sale is consummated in accordance with the
terms of this Agreement, neither the applicable Special Servicer nor the Trustee
shall have any liability to any Certificateholder with respect to the purchase
price therefor accepted by the applicable Special Servicer or the Trustee.

            (g) Any sale of any Specially Designated Defaulted Mortgage Loan or
REO Property shall be for cash only.

            (h) The purchase price for any Specially Designated Defaulted
Mortgage Loan or REO Property sold under this Section 3.18 shall be deposited
into the applicable Master Servicer's Collection Account, and the Trustee, upon
receipt of written notice from such Master Servicer to the effect that such
deposit has been made (based upon notification by the applicable Special
Servicer to such Master Servicer of the amount of the purchase price), shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, as shall be provided to it and are reasonably necessary to
vest ownership of such Mortgage Loan or REO Property in the Person who purchased
such Mortgage Loan or REO Property.

            (i) The parties hereto acknowledge the purchase option of each B
Loan Holder, the Washington Center Junior Holders and the Washington Center
mezzanine holder with respect to the related A Loan provided for in the related
A/B Intercreditor Agreement and that such option is prior in right to the Fair
Value Option. The purchase price paid by any B Loan Holder or Washington Center
Junior Holder, as applicable, for the related A Loan in accordance with such
purchase option shall be deposited into the Collection Account, and the Trustee,
upon receipt of written notice from the applicable Master Servicer to the effect
that such deposit has been made, shall execute and deliver such instruments of
transfer or assignment, in each case without recourse, as shall be provided to
it and are reasonably necessary to vest ownership of such Mortgage Loan in the
related B Loan Holder or Washington Center Junior Holder, as applicable.

            Section 3.19 Additional Obligations of Master Servicers and the
Special Servicers.

            (a) Each Master Servicer shall deliver to the Trustee for deposit in
the Distribution Account by 1:00 p.m. (New York City time) on each Master
Servicer Remittance Date, without any right of reimbursement therefor, a cash
payment (a "Compensating Interest Payment") in an amount equal to the sum of:

            (i) with respect to Prepayment Interest Shortfalls that arise other
      than by application of Insurance Proceeds and Condemnation Proceeds to the
      payment of principal on any Mortgage Loan, the lesser of (A) the aggregate
      amount of Prepayment Interest Shortfalls incurred in connection with
      Principal Prepayments received (including, in the case of the Great Lakes
      Crossing Mortgage Loan, by the Great Lakes Crossing Master Servicer or the
      Great Lakes Crossing Special Servicer on behalf of the Trust) during the
      most recently ended Collection Period with respect to Mortgage Loans as to
      which such Master Servicer is the applicable Master Servicer, and (B) the
      aggregate of (1)(a) with respect to all Mortgage Loans other than the
      Co-op Mortgage Loans, such Master Servicer's Master Servicing Fees for the
      related Collection Period for each and every Mortgage Loan and REO
      Mortgage Loan for which such Master Servicing Fees are being paid in such
      Collection Period, exclusive of any primary servicing fees payable to the
      applicable Master Servicer or any of those payable to a third-party
      Sub-Servicer (including any Designated Sub-Servicer), and (b) with respect
      to Co-op Mortgage Loans, the NCB Master Servicer's Master Servicing Fees
      for the related Collection Period for each and every Co-op Mortgage Loan
      and REO Mortgage Loan (which predecessor Mortgage Loan was a Co-op
      Mortgage Loan) for which such Master Servicing Fees are being paid in such
      Collection Period, exclusive of any Excess Servicing Fees payable to the
      NCB Master Servicer , and (2) all Prepayment Interest Excesses that were
      collected during the subject Collection Period with respect to Mortgage
      Loans for which that Master Servicer is acting as such and, to the extent
      earned on the particular Principal Prepayment, all Net Investment Earnings
      related to such Principal Prepayment received by such Master Servicer
      during the most recently ended Collection Period; provided, however, that
      if such a Prepayment Interest Shortfall occurs as a result of the
      applicable Master Servicer's allowing the related Borrower to deviate from
      the terms of the related Mortgage Loan Documents regarding Principal
      Prepayments (other than (X) subsequent to a material default under the
      related Mortgage Loan Documents, (Y) pursuant to applicable law or a court
      order, or (Z) at the request or with the consent of the Controlling Class
      Representative), then, for purposes of calculating the Compensating
      Interest Payment for the subject Collection Period and such Mortgage Loan,
      the rate referred to in clause (B)(1) above shall be, except with respect
      to the Co-op Mortgage Loans, deemed to include any related primary
      servicing fee payable to the applicable Master Servicer but shall not
      include any primary servicing fee payable to any third-party Sub-Servicer
      (including any Designated Sub-Servicer); and

            (ii) with respect to Prepayment Interest Shortfalls that arise by
      application of Insurance Proceeds or Condemnation Proceeds to payment of
      principal on any Mortgage Loan, the lesser of (A) the aggregate amount of
      Prepayment Interest Shortfalls incurred in connection with Insurance
      Proceeds and Condemnation Proceeds received and applied as an early
      recovery of principal during the most recently ended Collection Period
      with respect to Mortgage Loans as to which such Master Servicer is the
      applicable Master Servicer, and (B) all Net Investment Earnings earned on
      the portion of such Insurance Proceeds and Condemnation Proceeds that
      represents the particular Principal Prepayment, received by such Master
      Servicer during the most recently ended Collection Period.

            The rights of the Certificateholders to offset the aggregate
Prepayment Interest Shortfalls shall not be cumulative from Collection Period to
Collection Period.

            (b) No later than 1:00 p.m. New York City time on the first
Determination Date that follows the date on which a Special Servicer makes any
Servicing Advance, such Special Servicer shall provide the applicable Master
Servicer an Officer's Certificate (via facsimile) setting forth the details of
the Servicing Advance upon which the Master Servicer shall conclusively rely in
reimbursing such Special Servicer. The applicable Master Servicer shall be
obligated, out of such Master Servicer's own funds, to reimburse such Special
Servicer for any unreimbursed Servicing Advances (other than Nonrecoverable
Servicing Advances) made by such Special Servicer with respect to Mortgage Loans
and/or REO Properties as to which such Master Servicer is the applicable Master
Servicer, together with interest thereon at the Reimbursement Rate from the date
made to, but not including, the date of reimbursement. Any such reimbursement,
together with any accompanying payment of interest, shall be made by the
applicable Master Servicer, by wire transfer of immediately available funds to
an account designated by the requesting Special Servicer, no later than the
first Master Servicer Remittance Date that is at least three (3) Business Days
after the date on which the applicable Master Servicer receives the
corresponding Officer's Certificate contemplated by the prior sentence; provided
that any such Officer's Certificate received after 1:00 p.m., New York City
time, on any particular date shall, for purposes of any such reimbursement, be
deemed received on the next succeeding Business Day. Upon a Master Servicer's
reimbursement to a Special Servicer of any Servicing Advance and payment to such
Special Servicer of interest thereon, all in accordance with this Section
3.19(b), such Master Servicer shall for all purposes of this Agreement be deemed
to have made such Servicing Advance at the same time as such Special Servicer
actually made such Servicing Advance, and accordingly, such Master Servicer
shall be entitled to reimbursement for such Servicing Advance, together with
interest thereon in accordance with Sections 3.05(a) and 3.11(g), at the same
time, in the same manner and to the same extent as such Master Servicer would
otherwise have been entitled if it had actually made such Servicing Advance at
the time such Special Servicer did.

            Notwithstanding anything to the contrary contained in any other
Section of this Agreement, the applicable Special Servicer shall notify the
applicable Master Servicer whenever a Servicing Advance is required to be made
with respect to any Specially Serviced Mortgage Loan or REO Property, and, such
Master Servicer shall make such Servicing Advance; provided that the applicable
Special Servicer may make any Servicing Advance on a Specially Serviced Mortgage
Loan or REO Property only as may be required on an urgent or emergency basis.
Each such notice and request shall be made, in writing, in a timely manner that
does not adversely affect the interests of any Certificateholder, any B Loan
Holder (with respect to its related Mortgage Loan) or Washington Center Junior
Holder (with respect to the Washington Center Loan) (and, in any event, to the
extent reasonably practicable, at least five Business Days in advance of the
date on which the subject Servicing Advance is to be made) and shall be
accompanied by such information and documentation regarding the subject
Servicing Advance as the applicable Master Servicer may reasonably request;
provided, however, that a Special Servicer shall not be entitled to make such a
request (other than for emergency Advances) more frequently than once per
calendar month (although such request may relate to more than one Servicing
Advance). The applicable Master Servicer shall have the obligation to make any
such Servicing Advance (other than a Nonrecoverable Servicing Advance) that it
is so requested by a Special Servicer to make, within five Business Days of such
Master Servicer's receipt of such request. If the request is timely and properly
made, the requesting Special Servicer shall be relieved of any obligations with
respect to a Servicing Advance that it so requests the applicable Master
Servicer to make with respect to any Mortgage Loan or REO Property (regardless
of whether or not the applicable Master Servicer shall make such Servicing
Advance). Each Master Servicer shall be entitled to reimbursement for any
Servicing Advance made by it at the direction of a Special Servicer, together
with Advance Interest in accordance with Sections 3.05(a) and 3.11(g), at the
same time, in the same manner and to the same extent as such Master Servicer is
entitled with respect to any other Servicing Advances made thereby.

            Notwithstanding the foregoing provisions of this Section 3.19(b), a
Master Servicer shall not be required to reimburse a Special Servicer for, or to
make at the direction of a Special Servicer, any Servicing Advance if such
Master Servicer determines in its reasonable judgment that such Servicing
Advance, although not characterized by such Special Servicer as a Nonrecoverable
Servicing Advance, is in fact a Nonrecoverable Servicing Advance. Such Master
Servicer shall notify such Special Servicer in writing of such determination
and, if applicable, such Nonrecoverable Servicing Advance shall be reimbursed to
such Special Servicer pursuant to Section 3.05(a).

            (c) Promptly following the occurrence of an Appraisal Trigger Event
with respect to any Mortgage Loan, the applicable Special Servicer shall obtain
(or, if such Mortgage Loan has a Stated Principal Balance of $2,000,000 or less,
at such Special Servicer's option, conduct) an Appraisal of the related
Mortgaged Property, unless an Appraisal thereof had previously been obtained
(or, if applicable, conducted) within the preceding 12-month period and there
has been no subsequent material change in the circumstances surrounding the
related Mortgaged Property that, in the reasonable judgment of the applicable
Special Servicer, would materially affect the value of the property, and shall
deliver a copy of such Appraisal to the Trustee, the applicable Master Servicer
and the Controlling Class Representative. If such Appraisal is obtained from a
Qualified Appraiser, the cost thereof shall be covered by, and be reimbursable
to the applicable Master Servicer as, a Servicing Advance. Promptly following
the receipt of, and based upon, such Appraisal, such Special Servicer, in
consultation with the Controlling Class Representative, shall determine and
report to the Trustee, the applicable Master Servicer, any B Loan Holder (with
respect to its related Mortgage Loan) or Washington Center Junior Holder (with
respect to the Washington Center Loan), the then applicable Appraisal Reduction
Amount, if any, with respect to the subject Required Appraisal Loan.

            For so long as any Mortgage Loan or REO Mortgage Loan remains a
Required Appraisal Loan, the applicable Special Servicer shall, within 30 days
of each anniversary of such loan having become a Required Appraisal Loan, obtain
(or, if such Required Appraisal Loan has a Stated Principal Balance of
$2,000,000 or less, at such Special Servicer's option, conduct) an update of the
prior Appraisal. If such update is obtained from a Qualified Appraiser, the cost
thereof shall be covered by, and be reimbursable to the applicable Master
Servicer as, a Servicing Advance. Promptly following the receipt of, and based
upon, such update, such Special Servicer shall redetermine, in consultation with
the Controlling Class Representative, and report to the Trustee, the applicable
Master Servicer, any B Loan Holder (with respect to its related Mortgage Loan)
or Washington Center Junior Holder (with respect to the Washington Center Loan),
the then applicable Appraisal Reduction Amount, if any, with respect to the
subject Required Appraisal Loan.

            The Controlling Class Representative shall have the right at any
time within six months of the date of the receipt of any Appraisal to require
that the applicable Special Servicer obtain a new Appraisal of the subject
Mortgaged Property in accordance with MAI standards, at the expense of the
Controlling Class Certificateholders or, in respect of the Washington Center
Loan, the Controlling Class Representative of the Washington Center Loan, and
upon receipt of such Appraisal the applicable Special Servicer shall redetermine
the Appraisal Reduction Amount.

            (d) [RESERVED]

            (e) In connection with each prepayment of principal received
hereunder, the applicable Master Servicer shall calculate any applicable
Prepayment Premium or Yield Maintenance Charge, as the case may be. Promptly
following its determination thereof, the applicable Master Servicer shall
disclose to the Trustee, the Controlling Class Representative, any B Loan Holder
(with respect to its related Mortgage Loan) or Washington Center Junior Holder
(with respect to the Washington Center Loan) and, upon request, any
Certificateholder its calculation of any such Prepayment Premium or Yield
Maintenance Charge, including, in the case of a Yield Maintenance Charge, the
U.S. Treasury rate and, if different, the discount rate used to calculate such
Yield Maintenance Charge.

            (f) With respect to each Mortgage Loan that provides for defeasance,
the applicable Master Servicer shall, to the extent permitted by the terms of
such Mortgage Loan, require the related Borrower (i) to provide replacement
collateral consisting of U.S. government securities within the meaning of
Treasury Regulations Section 1.860G-2(a)(8)(i) in an amount sufficient to make
all scheduled payments under the Mortgage Loan (or defeased portion thereof)
when due (and assuming, in the case of an ARD Mortgage Loan, to the extent
consistent with the related Mortgage Loan Documents, that such Mortgage Loan
matures on its Anticipated Repayment Date), (ii) to deliver a certificate from
an independent certified public accounting firm certifying that the replacement
collateral is sufficient to make such payments, (iii) at the option of the
applicable Master Servicer, to designate a single purpose entity (which may be a
subsidiary of such Master Servicer established for the purpose of assuming all
defeased Mortgage Loans) to assume the Mortgage Loan (or defeased portion
thereof) and own the defeasance collateral, (iv) to implement such defeasance
only after the second anniversary of the Closing Date, (v) to provide an Opinion
of Counsel that the Trustee has a perfected, first priority security interest in
the new collateral, and (vi) in the case of a partial defeasance of the Mortgage
Loan, to defease a principal amount equal to at least 125% of the allocated loan
amount for the Mortgaged Property or Properties to be released. If the subject
Mortgage Loan has a Cut-off Date Principal Balance less than $20,000,000 and an
outstanding principal balance less than 2% of the then aggregate Stated
Principal Balance of the Mortgage Pool and is not one of the 10 largest Mortgage
Loans then in the Trust Fund, and if either the terms of the subject Mortgage
Loan permit the applicable Master Servicer to impose the foregoing requirements
or such Master Servicer satisfies such requirements on its own, then
confirmation that such defeasance will not result in an Adverse Rating Event is
not required so long as the applicable Master Servicer delivers to S&P a
certification in the form attached hereto as Exhibit N. In such case, the
applicable Master Servicer shall provide the Rating Agencies and the Controlling
Class Representative with notice that the foregoing requirements have been met
with respect to the subject Mortgage Loan. However, if the subject Mortgage Loan
has a Cut-off Date Principal Balance greater than or equal to $20,000,000 or an
outstanding principal balance greater than or equal to 2% of the aggregate
Stated Principal Balance of the Mortgage Pool or is one of the 10 largest
Mortgage Loans then in the Trust Fund, or if the terms of the subject Mortgage
Loan do not permit such Master Servicer to impose such requirements and such
Master Servicer does not satisfy such requirements on its own, then such Master
Servicer shall so notify the Rating Agencies and the Controlling Class
Representative and, so long as such a requirement would not violate applicable
law or the Servicing Standard, obtain a confirmation that such defeasance will
not result in an Adverse Rating Event. Subject to the related Mortgage Loan
Documents and applicable law, the applicable Master Servicer shall not execute a
defeasance unless (i) the subject Mortgage Loan requires the Borrower to pay all
Rating Agency fees associated with defeasance (if Rating Agency confirmation of
no-downgrade is a specific condition precedent thereto) and all expenses
associated with defeasance or other arrangements for payment of such costs are
made at no expense to the Trust Fund or the applicable Master Servicer
(provided, however, that in no event shall such proposed "other arrangements"
result in any liability to the Trust Fund including any indemnification of the
applicable Master Servicer or the applicable Special Servicer which may result
in legal expenses to the Trust Fund), and (ii) the Borrower is required to
provide all Opinions of Counsel, including Opinions of Counsel that the
defeasance will not cause an Adverse REMIC Event or an Adverse Grantor Trust
Event and that the Mortgage Loan Documents are fully enforceable in accordance
with their terms (subject to bankruptcy, insolvency and similar standard
exceptions), and any applicable rating confirmations.

            (g) The applicable Master Servicer shall, as to each Mortgage Loan
which is secured by the interest of the related Borrower under a Ground Lease,
promptly (and in any event within 45 days) after the Closing Date notify the
related ground lessor of the transfer of such Mortgage 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
applicable Master Servicer.

            (h) If a Mortgage Loan provides or allows that the related
Borrower's failure to make any Monthly Payment due thereunder on the applicable
Due Date will not result in an event of default for which such Mortgage Loan may
be accelerated and/or, except in the case of a Co-op Mortgage Loan, accrue
Default Charges unless and until the applicable Master Servicer notifies such
Borrower of the failure or the elapse of a specified number of days following
such Master Servicer's delivery of such notice, then such Master Servicer shall
promptly (and in any event within two Business Days following the applicable Due
Date) notify the related Borrower of such a failure. If a Co-op Mortgage Loan
provides or allows that the related Borrower's failure to make any Monthly
Payment due thereunder on the applicable Due Date will not result in an event of
default for which such Mortgage Loan may accrue Default Charges unless and until
the applicable Master Servicer notifies such Borrower of the failure or the
elapse of a specified number of days following the applicable Master Servicer's
delivery of such notice, then the applicable Master Servicer shall, in
accordance with such Master Servicer's customary practices and in accordance
with the Servicing Standard, notify the related Borrower of such a failure.

            Section 3.20 Modifications, Waivers, Amendments and Consents

collateral securing, and/or permit the release, addition or substitution of the
Borrower on or any guarantor of, any Mortgage Loan, and/or provide consents with
respect to any leasing activity at a Mortgaged Property securing any Mortgage
Loan; provided, that the Master Servicers' and the Special Servicers' respective
rights to do so shall be subject to Sections 3.08, 3.23, 3.24 and 3.27 (and, in
the case of any A Loan, B Loan or C Loan, subject to the terms of the related
A/B Intercreditor Agreement) and, further, to each of the following limitations,
conditions and restrictions:

            (i) other than as provided in Sections 2.03(b), 3.02(a) (relating to
      waiver of Default Charges), 3.08, 3.20(f) and 3.20(g), the applicable
      Master Servicer shall not agree to any modification, waiver, forbearance
      or amendment of any term of, or take any of the other acts referenced in
      this Section 3.20(a) with respect to, any Mortgage Loan, that would affect
      the amount or timing of any related payment of principal, interest or
      other amount payable under such Mortgage Loan or impair the security for
      such Mortgage Loan, unless such Master Servicer has obtained the consent
      of the applicable Special Servicer (it being understood and agreed that
      (A) such Master Servicer shall promptly provide the applicable Special
      Servicer with notice of any Borrower request for such modification,
      waiver, forbearance or amendment, such Master Servicer's recommendations
      and analysis, and with all information reasonably available to such Master
      Servicer that the applicable Special Servicer may reasonably request in
      order to withhold or grant any such consent, (B) the applicable Special
      Servicer shall decide whether to withhold or grant such consent in
      accordance with the Servicing Standard and (C) if any such consent has not
      been expressly denied within 10 Business Days (or, in the case of consents
      relating to leasing activities at Mortgaged Properties securing KeyBank
      Mortgage Loans and NCBFSB Mortgage Loans, within 3 Business Days) of the
      applicable Special Servicer's receipt from such Master Servicer of such
      Master Servicer's recommendations and analysis and all information
      reasonably requested thereby and reasonably available to such Master
      Servicer in order to make an informed decision (or, if the applicable
      Special Servicer did not request any information, within 10 Business Days
      from such notice), such consent shall be deemed to have been granted);

            (ii) other than as provided in Sections 3.02(a), 3.08 and 3.20(f),
      the applicable Special Servicer shall not agree to (or, in the case of a
      Performing Mortgage Loan, consent to the applicable Master Servicer's
      agreeing to, which consent shall be deemed given if not denied in writing
      within 10 Business Days) any modification, waiver or amendment of any term
      of, or take (or, in the case of a Performing Mortgage Loan, consent to the
      applicable Master Servicer's taking) any of the other acts referenced in
      this Section 3.20(a) with respect to, any Mortgage Loan that would affect
      the amount or timing of any related payment of principal, interest or
      other amount payable thereunder or, in the reasonable judgment of such
      Special Servicer, would materially impair the security for such Mortgage
      Loan, unless a material default on such Mortgage Loan has occurred or, in
      the reasonable judgment of such Special Servicer, a default in respect of
      payment on such Mortgage Loan is reasonably foreseeable, and such
      modification, waiver, amendment or other action is reasonably likely to
      produce a greater recovery to Certificateholders, any B Loan Holder or
      Washington Center Junior Holder (as a collective whole) on a present value
      basis (the relevant discounting of anticipated collections that will be
      distributable to Certificateholders to be done at the related Net Mortgage
      Rate), than would liquidation;

            (iii) the applicable Special Servicer shall not extend (or, in the
      case of a Performing Mortgage Loan, consent to the applicable Master
      Servicer's extending, which consent shall be deemed given if not denied in
      writing within 10 Business Days) the date on which any Balloon Payment is
      scheduled to be due on any Mortgage Loan to a date beyond the earliest of
      (A) the fifth anniversary of such Mortgage Loan's Stated Maturity Date,
      (B) two years prior to the Rated Final Distribution Date, (C) if such
      Mortgage Loan is secured by a Mortgage solely or primarily on the related
      Borrower's leasehold interest in the related Mortgaged Property, 20 years
      (or, to the extent consistent with the Servicing Standard, giving due
      consideration to the remaining term of the Ground Lease, 10 years) prior
      to the end of the then current term of the related Ground Lease (plus any
      unilateral options to extend), and (D) if such Mortgage Loan is covered by
      an Environmental Insurance Policy, two years prior to the expiration of
      the term of such policy unless the applicable Special Servicer shall have
      first determined in its reasonable judgment, based upon a Phase I
      Environmental Assessment (and any additional environmental testing that
      the applicable Special Servicer deems necessary and prudent) conducted by
      an Independent Person who regularly conducts Phase I Environmental
      Assessments, and at the expense of the Borrower, that there are no
      circumstances or conditions present at the related Mortgaged Property for
      which investigation, testing, monitoring, containment, clean-up or
      remediation would be required under any then applicable environmental laws
      or regulations;

            (iv) neither the applicable Master Servicer nor the applicable
      Special Servicer shall make or permit any modification, waiver or
      amendment of any term of, or take any of the other acts referenced in this
      Section 3.20(a) with respect to, any Mortgage Loan that would result in an
      Adverse REMIC Event with respect to any Trust REMIC or an Adverse Grantor
      Trust Event with respect to the Grantor Trust;

            (v) subject to applicable law, the related Mortgage Loan Documents
      and the Servicing Standard, neither the applicable Master Servicer nor the
      applicable Special Servicer shall permit any modification, waiver or
      amendment of any term of any Performing Mortgage Loan unless all related
      fees and expenses are paid by the Borrower;

            (vi) neither the applicable Special Servicer nor the applicable
      Master Servicer shall permit (and, in the case of a Performing Mortgage
      Loan, the applicable Special Servicer shall not consent to the applicable
      Master Servicer's permitting, which consent shall be deemed given if not
      denied in writing within 10 Business Days) any Borrower to add or
      substitute any real estate collateral for its Mortgage Loan unless the
      applicable Special Servicer shall have first (A) determined in its
      reasonable judgment, based upon a Phase I Environmental Assessment (and
      any additional environmental testing that such Special Servicer deems
      necessary and prudent) conducted by an Independent Person who regularly
      conducts Phase I Environmental Assessments, at the expense of the related
      Borrower, that such additional or substitute collateral is in compliance
      with applicable environmental laws and regulations and that there are no
      circumstances or conditions present with respect to such new collateral
      relating to the use, management or disposal of any Hazardous Materials for
      which investigation, testing, monitoring, containment, clean-up or
      remediation would be required under any then applicable environmental laws
      or regulations and (B) received, at the expense of the related Borrower,
      written confirmation from each Rating Agency that such addition or
      substitution of collateral will not, in and of itself, result in an
      Adverse Rating Event with respect to any Class of Rated Certificates; and

            (vii) neither the applicable Special Servicer nor the applicable
      Master Servicer shall release (and, in the case of a Performing Mortgage
      Loan, the applicable Special Servicer shall not consent to the applicable
      Master Servicer's releasing, which consent shall be deemed given if not
      denied in writing within 10 Business Days), including in connection with a
      substitution contemplated by clause (vi) above, any real property
      collateral securing an outstanding Mortgage Loan, except as provided in
      Section 3.09(d) or 3.20(g) or except in connection with a permitted
      defeasance, or except where a Mortgage Loan (or, in the case of a
      Cross-Collateralized Group, where such entire Cross-Collateralized Group)
      is satisfied, or except in the case of a release of real property
      collateral provided (A) the Rating Agencies have been notified in writing,
      (B) either (1) such release will not, in the reasonable judgment of such
      Special Servicer, materially and adversely affect the net operating income
      being generated by or the then-current use of the related Mortgaged
      Property, or (2) there is a corresponding principal pay down of such
      Mortgage Loan in an amount at least equal to the appraised value of the
      collateral to be released (or substitute real property collateral with an
      appraised value at least equal to that of the collateral to be released,
      is delivered), (C) the release does not materially adversely affect the
      adequacy of the remaining Mortgaged Property (together with any substitute
      real property collateral), in the reasonable judgment of such Special
      Servicer, as security for the remaining Mortgage Loan and (D) if the real
      property collateral to be released has an appraised value in excess of
      $1,500,000, such release would not, in and of itself, result in an Adverse
      Rating Event with respect to any Class of Rated Certificates (as confirmed
      in writing to the Trustee by each Rating Agency);

provided, that the limitations, conditions and restrictions set forth in clauses
(i) through (vii) above shall not apply to any act or event (including, without
limitation, a release, substitution or addition of collateral) in respect of any
Mortgage Loan that either occurs automatically, or results from the exercise of
a unilateral option by the related Borrower within the meaning of Treasury
Regulations Section 1.1001-3(c)(2)(iii), in any event under the terms of such
Mortgage Loan in effect on the Closing Date (or, in the case of a Replacement
Mortgage Loan, on the related date of substitution); and provided, further,
that, notwithstanding clauses (i) through (vii) above, neither the applicable
Master Servicer nor the applicable Special Servicer shall be required to oppose
the confirmation of a plan in any bankruptcy or similar proceeding involving a
Borrower if, in its reasonable judgment, such opposition would not ultimately
prevent the confirmation of such plan or one substantially similar; and
provided, further, that, notwithstanding clause (vii) above, neither the
applicable Master Servicer nor the applicable Special Servicer shall be required
to obtain any confirmation of the Certificate ratings from the Rating Agencies
in order to grant easements or rights of way that do not materially affect the
use or value of a Mortgaged Property or the Borrower's ability to make any
payments with respect to the related Mortgage Loan.

            (b) Neither of the Special Servicers and neither of the Master
Servicers shall have any liability to the Trust, the Certificateholders or any
other Person if its analysis and determination that the modification, waiver,
amendment or other action contemplated by Section 3.20(a) is reasonably likely
to produce a greater recovery to Certificateholders and with respect to the 622
Third Avenue Loan or the Washington Center Loan, the B Loan Holder and each
Washington Center Junior Holder, respectively, as a collective whole (taking
into account the subordination of the B Loan to the related Mortgage Loan and,
in the case of the Washington Center Total Loan, the subordination of the C Loan
to the related B Loan and the Washington Center Loan), on a present value basis
than would liquidation should prove to be wrong or incorrect, so long as the
analysis and determination were made on a reasonable basis by such Special
Servicer and/or such Master Servicer, and consistent with the Servicing
Standard.

            (c) Any payment of interest, which is deferred pursuant to Section
3.20(a), shall not, for purposes of calculating monthly distributions and
reporting information to Certificateholders, be added to the unpaid principal
balance or Stated Principal Balance of the related Mortgage Loan,
notwithstanding that the terms of such Mortgage Loan so permit or that such
interest may actually be capitalized; provided, however, that this sentence
shall not limit the rights of the applicable Master Servicer or the applicable
Special Servicer on behalf of the Trust to enforce any obligations of the
related Borrower under such Mortgage Loan.

            (d) Each Master Servicer and each Special Servicer may, as a
condition to its granting any request by a Borrower for consent, modification,
waiver or indulgence or any other matter or thing, the granting of which is
within the discretion of such Master Servicer's or such Special Servicer's, as
the case may be, pursuant to the terms of the related Mortgage Loan Documents
and is permitted by the terms of this Agreement, require that such Borrower pay
to it a reasonable or customary fee (which shall in no event exceed 1.0% of the
unpaid principal balance of the related Mortgage Loan) for the additional
services performed in connection with such request, together with any related
costs and expenses incurred by it; provided that the charging of such fee that
is not otherwise provided for by the terms of the Mortgage Loan does not
constitute a "significant modification" of the Mortgage Loan pursuant to
Treasury Regulations Section 1.860G-2(b). All such fees collected by a Master
Servicer and/or a Special Servicer with respect to any Mortgage Loan shall be
allocable between such parties, as Additional Master Servicing Compensation and
Additional Special Servicing Compensation, respectively, as provided in Section
3.11.

            (e) All modifications, amendments, material waivers and other
material actions entered into or taken in respect of the Mortgage Loans pursuant
to this Section 3.20 (other than waivers of Default Charges), and all consents,
shall be in writing; provided, that with respect to the 622 Third Avenue Loan
and the Washington Center Loan, the waiver of Default Charges shall be in
writing if there is no Additional Master Servicing Compensation or Additional
Special Servicing Compensation to offset any outstanding Advance Interest;
provided, further, that with respect to the Mortgage Loans identified on the
Mortgage Loan Schedule as One Penn Center and The Crossings, to the extent
permitted under the related Loan Documents, the applicable Master Servicer shall
not consent to any amendment of the organizational documents of the related
Borrower or any of its members or partners, as applicable, without obtaining
written confirmation from S&P that such amendment would not cause an Adverse
Rating Event. Each Special Servicer and each Master Servicer shall notify the
other such applicable party, each Rating Agency, the Trustee and the Controlling
Class Representative and, with respect to the 622 Third Avenue Loan and the
Washington Center Loan, the 622 Third Avenue B Loan Holder and each Washington
Junior Holder, respectively, in writing, of any modification, waiver, amendment
or other action entered into or taken thereby in respect of any Mortgage Loan
pursuant to this Section 3.20 that would affect the timing, payment or other
material terms of or otherwise materially impair the security for the subject
Mortgage Loan (other than waivers of Default Charges) and the date thereof, and,
in any event, shall deliver to the Trustee or the related Custodian for deposit
in the related Mortgage File (with a copy to the other such party), an original
counterpart of the agreement relating to such modification, waiver, amendment or
other action, promptly (and in any event within ten Business Days) following the
execution thereof. In addition, following the execution of any modification,
waiver or amendment agreed to by the applicable Special Servicer or by a Master
Servicer with the consent of the applicable Special Servicer, as appropriate,
pursuant to Section 3.20(a) above, the applicable Special Servicer or the
applicable Master Servicer, as applicable, shall deliver to the other such
party, the Trustee and the Rating Agencies an Officer's Certificate certifying
that all of the requirements of Section 3.20(a) have been met and, in the case
of the applicable Special Servicer, setting forth in reasonable detail the basis
of the determination made by it pursuant to Section 3.20(a)(ii).

            (f) With respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, the applicable Master Servicer shall be permitted, with the
consent of the applicable Special Servicer (which consent shall be deemed
granted if not denied in writing within 10 Business Days after receipt of the
applicable Master Servicer's request therefor), to waive (such waiver to be in
writing addressed to the related Borrower, with a copy to the Trustee) all or
any portion of the accrued Post-ARD Additional Interest in respect of such ARD
Mortgage Loan if (i) such ARD Mortgage Loan is a Performing Mortgage Loan, (ii)
the related Borrower has requested the right to prepay such ARD Mortgage Loan in
full together with all payments required by the related Mortgage Loan Documents
in connection with such prepayment except for such accrued Post-ARD Additional
Interest, and (iii) the applicable Master Servicer has determined, in its
reasonable judgment, that waiving such Post-ARD Additional Interest is in
accordance with the Servicing Standard. The applicable Master Servicer shall
prepare all documents necessary and appropriate to effect any such waiver and
shall coordinate with the related Borrower for the execution and delivery of
such documents.

            (g) Notwithstanding anything in this Section 3.20 or in Section 3.08
or Section 3.24 (but subject to Section 3.27) to the contrary, a Master Servicer
shall not be required to seek the consent of, or provide prior notice to, the
applicable Special Servicer or any Certificateholder (including the Controlling
Class Representative) or obtain any confirmation of the Certificate ratings from
the Rating Agencies in order to approve the following modifications, waivers or
amendments of the Mortgage Loans (but, in the case of the actions described in
clauses (iii) and (iv) of this sentence, shall notify the Controlling Class
Representative thereof): (i) waivers of minor covenant defaults (other than
financial covenants), including late financial statements; (ii) waivers of
Default Charges, to the extent allowed under Section 3.02, and permitting
subordinate debt with respect to Co-op Mortgage Loans as to which the NCBFSB
Subordinate Debt Conditions have been satisfied, in accordance with Section
3.08; (iii) releases of parcels of a Mortgaged Property (provided that any such
releases (A) are releases as to which the related Mortgage Loan Documents
expressly require the Mortgagee thereunder to make such releases upon the
satisfaction of certain conditions and such releases shall be made as required
by the Mortgage Loan Documents, or (B) are related to any pending or threatened
condemnation action); (iv) grants of easements or rights of way that do not
materially affect the use or value of a Mortgaged Property or the Borrower's
ability to make any payments with respect to the related Mortgage Loan; (v) if
the subject Mortgage Loan is (A) not a KeyBank Mortgage Loan or NCBFSB Mortgage
Loan, approval of routine leasing activities that affect less than the lesser of
30% of the net rentable area of the related Mortgaged Property or 30,000 square
feet of the related Mortgaged Property, (B) a KeyBank Mortgage Loan or NCBFSB
Mortgage Loan with an unpaid principal balance of greater than $3,000,000,
approval of routine leasing activities that affect less than 30,000 square feet
of the related Mortgaged Property, or (C) a KeyBank Mortgage Loan or NCBFSB
Mortgage Loan with an unpaid principal balance of $3,000,000 or less, approval
of any routine leasing activity; (vi) approval of annual budgets to operate the
Mortgaged Property; and (vii) temporary waivers of any requirements in the
related Mortgage Loan Documents with respect to insurance deductible amounts or
claims-paying ability ratings of insurance providers; provided that any such
modification, waiver or amendment, or agreeing to any such modification, waiver
or amendment, (w) would not in any way affect a payment term of the
Certificates, any B Loan or Washington Center Junior Loan, (x) would not
constitute a "significant modification" of such Mortgage Loan pursuant to
Treasury Regulations Section 1.860G-2(b) and would not otherwise constitute an
Adverse REMIC Event with respect to any Trust REMIC or an Adverse Grantor Trust
Event with respect to the Grantor Trust, (y) would be consistent with the
Servicing Standard, and (z) shall not violate the terms, provisions or
limitations of this Agreement or any other document contemplated hereby.

            (h) The applicable Master Servicer shall not terminate or replace,
or consent to the termination or replacement of, any property manager with
respect to any Mortgaged Property, and the applicable Master Servicer shall not
terminate or change or consent to the termination or change of the franchise for
any Mortgage Property operated as a hospitality property, in any event without
the prior written consent of the applicable Special Servicer (it being
understood and agreed that (A) such Master Servicer shall promptly provide such
Special Servicer with its analysis, recommendations and all information that
such Special Servicer may reasonably request and which information is in the
possession of such Master Servicer, in order to withhold or grant any such
consent, (B) subject to Section 3.24 and Section 3.27, such Special Servicer
shall decide whether to withhold or grant such consent in accordance with the
Servicing Standard, (C) if any such consent has not been expressly denied within
10 Business Days of such Special Servicer's receipt from such Master Servicer of
such analysis, recommendation and all information reasonably requested thereby
in order to make an informed decision (or, if such Special Servicer did not
request any information, within 10 Business Days from such notice), such consent
shall be deemed to have been granted and (D) such consent shall not be required
with respect to Co-op Mortgage Loans that are Performing Mortgage Loans);
provided, that in the case of the Mortgage Loans identified on the Mortgage Loan
Schedule as One Penn Center and The Crossings, to the extent permitted under the
related Loan Documents, the applicable Master Servicer shall not terminate or
replace, or consent to the termination or replacement of, any property manager
with respect to the related Mortgaged Property, unless it has received written
confirmation from S&P that an Adverse Rating Event would not occur if the
applicable Master Servicer terminated or replaced such property manager or
consented to such termination or replacement.

            (i) In connection with granting an extension of the maturity date of
any Mortgage Loan in accordance with Section 3.20(a), the applicable Special
Servicer, in the case of a Specially Serviced Mortgage Loan, and the applicable
Master Servicer, in the case of a Performing Mortgage Loan, shall each cause the
related Borrower to agree, if it has not already done so pursuant to the
existing Mortgage Loan Documents, to thereafter deliver to the applicable
Special Servicer, the Controlling Class Representative and, upon request, the
Trustee annual audited operating statements and quarterly unaudited operating
statements with respect to the related Mortgaged Property, provided that the
applicable Special Servicer or the applicable Master Servicer, as the case may
be, may, in its sole discretion, waive the requirement that such statements be
audited.

            (j) Notwithstanding anything in this Agreement, including this
Section 3.20, to the contrary, for so long as the applicable Master Servicer and
the applicable Special Servicer are the same Person, the applicable Master
Servicer shall not be obligated to obtain the consent or approval of the
applicable Special Servicer as otherwise required in this Agreement but shall
instead be required to request the consent or approval of the Controlling Class
Representative (in respect of any matter as to which such consent is otherwise
required hereunder) to the extent, and on the same terms, subject to the same
limitations, restrictions and exclusions and within the same time periods as,
the applicable Special Servicer is required to request such consent or approval
of the Controlling Class Representative pursuant to Section 3.24 or Section
3.27, as applicable, or any other section or provision of this Agreement.

            (k) None of the Master Servicer, the Special Servicer or the Trustee
shall agree to any amendment or supplement to or modification or termination of
either Great Lakes Crossing Intercreditor Agreement or any Great Lakes Crossing
Servicing Agreement unless (i) it shall have obtained (A) the consent of the
Controlling Class Representative (which consent shall be deemed given if the
subject servicing action is not disapproved by the Controlling Class
Representative within 10 Business Days) and (B) written confirmation from each
Rating Agency that such amendment, supplement or modification will not result in
an Adverse Rating Event with respect to any Class of Rated Certificates and (ii)
it shall have received an Opinion of Counsel to the effect that such amendment,
supplement or modification will not result in an Adverse REMIC Event or an
Adverse Grantor Trust Event.

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

            (a) Upon determining that a Servicing Transfer Event has occurred
with respect to any Mortgage Loan, the applicable Master Servicer shall
immediately give notice thereof to the Controlling Class Representative, and if
the applicable Master Servicer is not also the applicable Special Servicer, such
Master Servicer shall immediately give notice thereof to the applicable Special
Servicer, the Trustee and the Controlling Class Representative, shall deliver
the related Servicing File to the applicable Special Servicer and shall use its
best efforts to provide such Special Servicer with all information, documents
(or copies thereof) and records (including records stored electronically on
computer tapes, magnetic discs and the like) relating to the Mortgage Loan and
reasonably requested by the applicable Special Servicer to enable it to assume
its functions hereunder with respect thereto without acting through a
Sub-Servicer. To the extent such is in the possession of the applicable Master
Servicer or any Sub-Servicer thereof, the information, documents and records to
be delivered by such Master Servicer to the applicable Special Servicer pursuant
to the prior sentence shall include, but not be limited to, financial
statements, appraisals, environmental/engineering reports, leases, rent rolls
(or, in the case of a residential cooperative property, maintenance schedules),
title insurance policies, UCC's and tenant estoppels. The applicable Master
Servicer shall use its best efforts to comply with the preceding two sentences
within five Business Days of the occurrence of each related Servicing Transfer
Event. No later than ten Business Days before the applicable Master Servicer is
required to deliver a copy of the related Servicing File to the applicable
Special Servicer, it shall review such Servicing File and request from the
Trustee any material documents that it is aware are missing from such Servicing
File. Any B Loan or Washington Center Junior Loan shall constitute a Specially
Serviced Mortgage Loan for which the applicable Special Servicer is responsible
for so long as the related A Loan is a Specially Serviced Mortgage Loan.

            Upon determining that a Specially Serviced Mortgage Loan has become
a Corrected Mortgage Loan and if the applicable Master Servicer is not also the
applicable Special Servicer, such Special Servicer shall immediately give notice
thereof to the applicable Master Servicer, the Trustee and the Controlling Class
Representative and shall return the related Servicing File within five Business
Days, to the applicable Master Servicer. Upon giving such notice and returning
such Servicing File to the applicable Master Servicer, such Special Servicer's
obligation to service such Mortgage Loan, and such Special Servicer's right to
receive the Special Servicing Fee with respect to such Mortgage Loan, shall
terminate, and the obligations of the applicable Master Servicer to service and
administer such Mortgage Loan shall recommence. With respect to the 622 Third
Avenue Loan and the Washington Center Loan, in determining whether such Mortgage
Loan has become a Corrected Mortgage Loan, the related B Loan and Washington
Center Junior Loans, respectively, must also be determined to be a Corrected
Mortgage Loan for the Special Servicer's obligation to terminate for such
Mortgage Loan. Any CBA B Loan shall constitute a Specially Serviced Mortgage
Loan for which the Special Servicer is responsible for so long as the related
CBA A Loan is a Specially Serviced Mortgage Loan.

            Notwithstanding anything herein to the contrary, in connection with
the transfer to the applicable Special Servicer of the servicing of a
Cross-Collateralized Mortgage Loan as a result of a Servicing Transfer Event or
the re-assumption of servicing responsibilities by the applicable Master
Servicer with respect to any such Mortgage Loan upon its becoming a Corrected
Mortgage Loan, such Master Servicer and such Special Servicer shall each
transfer to the other, as and when applicable, the servicing of all other
Cross-Collateralized Mortgage Loans constituting part of the same
Cross-Collateralized Group; provided that no Cross-Collateralized Mortgage Loan
may become a Corrected Mortgage Loan at anytime that a continuing Servicing
Transfer Event exists with respect to another Cross-Collateralized Mortgage Loan
in the same Cross-Collateralized Group.

            (b) In servicing any Specially Serviced Mortgage Loan, the
applicable Special Servicer shall provide to the Trustee originals of documents
contemplated by the definition of "Mortgage File" and generated while such
Mortgage Loan is a Specially Serviced Mortgage Loan, for inclusion in the
related Mortgage File (with a copy of each such original to the applicable
Master Servicer), and copies of any additional related Mortgage Loan
information, including correspondence with the related Borrower generated while
such Mortgage Loan is a Specially Serviced Mortgage Loan.

            (c) Each Master Servicer and each Special Servicer shall furnish to
each other, upon reasonable request, such reports, documents, certifications and
information in its possession, and access to such books and records maintained
thereby, as may relate to any Mortgage Loan or REO Property and as shall be
reasonably required by the requesting party in order to perform its duties
hereunder.

            (d) In connection with the performance of its obligations hereunder
with respect to any Mortgage Loan or REO Property, each Master Servicer and each
Special Servicer shall be entitled to rely upon written information provided to
it by the other.

            (e) With respect to the 622 Third Avenue Total Loan and the
Washington Center Total Loan, no later than 45 days after receipt by the Special
Servicer of the information reasonably required by the Special Servicer after a
Servicing Transfer Event for the 622 Third Avenue Loan and the Washington Center
Loan, the Special Servicer shall deliver a report to the related B Loan Holder
or in the case of the Washington Center Total Loan, the Washington Center Junior
Holders, and Controlling Class Representative. In addition, for so long as the
Mortgage Loan is a Specially Serviced Mortgage Loan, with respect to any item in
any such previously delivered report that changes in any material respect
(whether as a result of a new determination, new information or otherwise), the
applicable Special Servicer shall use its best efforts to prepare or cause to be
prepared, a revised report within fifteen (15) Business Days after the date of
such determination or the receipt of such new information by the applicable
Special Servicer, but in any event no later than thirty (30) Business Days after
the receipt of such information. Such report shall set forth the following
information to the extent reasonably determinable:

            (i) summary of the status of such Specially Serviced Mortgage 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) the recommendations by the Special Servicer as to how such
      Specially Serviced Mortgage Loan might be returned to performing status
      and returned to the Master Servicer for regular servicing or otherwise
      realized upon;

            (vi) a summary of any proposed actions and an analysis of whether or
      not taking such action is reasonably likely to produce a greater recovery
      on a present value basis than not taking such action, setting forth the
      basis on which the Special Servicer made such determination;

            (vii) the status of any foreclosure actions or other proceedings
      undertaken with respect to such mortgaged real property, any proposed
      workouts with respect thereto and the status of any negotiations with
      respect to such workouts, and an assessment of the likelihood of
      additional events of default thereon; and

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

            Section 3.22 Sub-Servicing Agreements

            (a) Each Master Servicer and, subject to Section 3.22(f), Special
Servicer may enter into Sub-Servicing Agreements to provide for the performance
by third parties of any or all of their respective obligations hereunder
(including the performance on a regular basis by third parties of discrete tasks
in respect of a discrete number of assets), provided that, in each case, the
Sub-Servicing Agreement, including any amendments thereto and modifications
thereof: (i) insofar as it affects the Trust, is consistent with this Agreement,
including Section 7.01(a), in all material respects and requires the subject
Sub-Servicer to comply in all material respects with all of the applicable
conditions of this Agreement; (ii) provides that if such Master Servicer or such
Special Servicer, as the case may be, shall for any reason no longer act in such
capacity hereunder (including by reason of an Event of Default), the Trustee or
its designee or any other successor to such Master Servicer or such Special
Servicer, as the case may be, may thereupon assume all of the rights and, except
to the extent they arose prior to the date of assumption, obligations of such
Master Servicer or such Special Servicer, as the case may be, under such
agreement or, alternatively, may terminate such Sub-Servicing Agreement without
cause and without payment of any penalty or termination fee (provided, however,
that a Designated Sub-Servicer Agreement may not be terminated except for cause,
which will include the occurrence of any Adverse Rating Event resulting from the
subject Sub-Servicer's acting in such capacity); (iii) provides that the
Trustee, for the benefit of the Certificateholders, shall be a third party
beneficiary under such agreement, but that (except to the extent the Trustee or
its designee assumes the obligations of such Master Servicer or Special
Servicer, as the case may be, thereunder as contemplated by the immediately
preceding clause (ii), and except with respect to the obligations of any
successor Master Servicer under the Designated Sub-Servicer Agreements) none of
the Trustee, any successor to such Master Servicer or Special Servicer, as the
case may be, or any Certificateholder shall have any duties under such agreement
or any liabilities arising therefrom except as explicitly set forth herein; (iv)
permits any purchaser of a Mortgage Loan pursuant to this Agreement to terminate
such agreement with respect to such purchased Mortgage Loan at its option and
without penalty; (v) does not permit the subject Sub-Servicer to foreclose on a
Mortgaged Property or to enter into or consent to any modification, waiver or
amendment or otherwise take any action on behalf of such Master Servicer or
Special Servicer, as the case may be, contemplated by Section 3.08, 3.09 and/or
Section 3.20 hereof, without the consent of such Master Servicer or Special
Servicer, as the case may be, and in any event except on the same terms and
conditions as would be applicable if such Master Servicer or Special Servicer,
as the case may be, took such action; and (vi) does not permit the subject
Sub-Servicer any rights of indemnification out of the Trust Fund except through
such Master Servicer or Special Servicer, as the case may be, pursuant to
Section 6.03; provided that the appointment by such Master Servicer or Special
Servicer of a third-party contractor for the purpose of performing discrete,
ministerial functions shall not be subject to this Section 3.22 (except that
such Master Servicer or Special Servicer, as the case may be, shall remain
responsible for the actions of such third-party contractors and shall pay all
fees and expenses of such third-party contractors, unless otherwise expressly
provided herein). No Sub-Servicing Agreement entered into by a Master Servicer
shall purport to delegate or effectively delegate to the related Sub-Servicer
any of the rights or obligations of a Special Servicer with respect to any
Specially Serviced Mortgage Loan or otherwise. Each Sub-Servicing Agreement
entered into by a Special Servicer shall relate only to Specially Serviced
Mortgage Loans and any REO Properties as to which such Special Servicer acts as
Special Servicer and shall not purport to delegate or effectively delegate to
the related Sub-Servicer any of the rights or obligations of a Master Servicer
with respect to any Mortgage Loan, including any Specially Serviced Mortgage
Loan. Each Master Servicer and each Special Servicer shall each notify the
Trustee, the Controlling Class Representative and the Depositor in writing
promptly of the appointment by it of any Sub-Servicer. Each Master Servicer and
each Special 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. References in
this Agreement to actions taken or to be taken by a Master Servicer or a Special
Servicer include actions taken or to be taken by a Sub-Servicer on behalf of a
Master Servicer or a Special Servicer, as the case may be; and, in connection
therewith, all amounts advanced by any Sub-Servicer to satisfy the obligations
of a Master Servicer or a Special Servicer hereunder to make Advances shall be
deemed to have been advanced by such Master Servicer or such Special Servicer,
as the case may be, out of its own funds and, accordingly, such Advances shall
be recoverable by such Sub-Servicer in the same manner and out of the same funds
as if such Sub-Servicer were such Master Servicer or such Special Servicer, as
the case may be. Such Advances shall accrue interest in accordance with Sections
3.11(g) and/or 4.03(d), such interest to be allocable between the applicable
Master Servicer or the applicable Special Servicer, as the case may be, and such
Sub-Servicer as they may agree. For purposes of this Agreement, each Master
Servicer and each Special Servicer shall be deemed to have received any payment
when a Sub-Servicer retained by it receives such payment.

            (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 to ensure the
enforceability of the subject Mortgage Loans and to avoid any loss or liability
to the Master Servicers, the Special Servicers or the Trust.

            (c) Each Master Servicer and each Special Servicer, for the benefit
of the Trustee and the Certificateholders, shall (at no expense to the other
such party hereto or to the Certificateholders or the Trust) monitor the
performance and enforce the obligations of their respective Sub-Servicers under
the related Sub-Servicing Agreements. Such enforcement, including 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 such
Master Servicer or such Special Servicer, as applicable, in its reasonable
judgment, would require were it the owner of the subject Mortgage Loans. Subject
to the terms of the related Sub-Servicing Agreement, including any provisions
thereof limiting the ability of such Master Servicer or such Special Servicer,
as applicable, to terminate a Sub-Servicer, such Master Servicer and such
Special Servicer shall each have the right to remove a Sub-Servicer retained by
it at any time it considers such removal to be in the best interests of
Certificateholders.

            (d) If a Master Servicer or a Special Servicer ceases to serve as
such under this Agreement for any reason (including by reason of an Event of
Default), then the Trustee or other successor to such Master Servicer or Special
Servicer, as the case may be, shall succeed to the rights and assume the
obligations of such Master Servicer or such Special Servicer under any
Sub-Servicing Agreement to which such Master Servicer or Special Servicer, as
the case may be, are parties, unless the Trustee or other successor Master
Servicer or Special Servicer elects to terminate any such Sub-Servicing
Agreement in accordance with its terms and Section 3.22(a)(ii) hereof; provided
that no Designated Sub-Servicer Agreement may be so terminated except for cause,
which will include the occurrence of any Adverse Rating Event resulting from the
subject Sub-Servicer's acting in such capacity. In any event, if a Sub-Servicing
Agreement is to be assumed by the Trustee or other successor to a Master
Servicer or Special Servicer, then such Master Servicer or such Special
Servicer, as applicable, at its expense shall, upon request of the Trustee,
deliver to the assuming party all documents and records relating to such
Sub-Servicing Agreement and the Mortgage Loans then being serviced thereunder
and an accounting of amounts collected and held on behalf of it thereunder, and
otherwise use reasonable efforts to effect the orderly and efficient transfer of
the Sub-Servicing Agreement to the assuming party.

            (e) Notwithstanding any Sub-Servicing Agreement entered into by it,
each Master Servicer and each Special Servicer shall remain obligated and liable
to the Trustee and the Certificateholders for the performance of their
respective obligations and duties under this Agreement in accordance with the
provisions hereof to the same extent and under the same terms and conditions as
if each alone were servicing and administering the Mortgage Loans or REO
Properties for which it is responsible. No appointment of a Sub-Servicer shall
result in any additional expense to the Trustee, the Certificateholders or the
Trust other than those contemplated herein, and the fees of such Sub-Servicer
shall be payable by the Master Servicer or Special Servicer that retained it,
regardless of whether such Master Servicer's or Special Servicer's, as the case
may be, compensation hereunder is sufficient to cover such fees.

            (f) A Special Servicer shall not enter into any Sub-Servicing
Agreement unless either: (i) the Rating Agencies have confirmed in writing that
entering into such agreement will not result in an Adverse Rating Event; (ii)
such agreement relates to one or more Mortgage Loans (including any such
Mortgage Loan(s) previously sub-serviced in accordance with this Section 3.22)
that together represent less than 25% of the aggregate outstanding principal
balance of all Specially Serviced Mortgage Loans; or (iii) the Controlling Class
Representative has consented.

            Section 3.23 Controlling Class Representative

            (a) The Holders (or, in the case of Book-Entry Certificates, the
Certificate Owners) of Certificates representing more than 50% of the Class
Principal Balance of the Controlling Class shall be entitled in accordance with
this Section 3.23 to select a representative (the "Controlling Class
Representative") having the rights and powers specified in this Agreement
(including those specified in Section 3.24) or to replace an existing
Controlling Class Representative; provided that, subject to the last sentence of
this Section 3.23(a), and the acquisition by ARCap CMBS Fund REIT, Inc. of the
Certificates of the Controlling Class, ARCap CMBS Fund REIT, Inc. shall serve as
the initial Controlling Class Representative and, provided, further that the
Controlling Class Representative for the 622 Third Avenue Total Loan shall
initially be the holder of the 622 Third Avenue B Loan, and upon the occurrence
of a Control Appraisal Event shall be the Holders of a majority of the Class 622
Participation Certificates and, with respect to the Washington Center Total
Loan, the initial Controlling Class Representative shall be the Washington
Center C Loan Holder and, upon the occurrence of a Control Appraisal Event shall
be the Washington Center B Loan Holder. Upon (i) the receipt by the Trustee of
written requests for the selection of a successor Controlling Class
Representative from the Holders (or, in the case of Book-Entry Certificates, the
Certificate Owners) of Certificates representing more than 50% of the Class
Principal Balance of the Controlling Class, (ii) the resignation or removal of
the Person acting as Controlling Class Representative or (iii) a determination
by the Trustee that the Controlling Class has changed, the Trustee shall
promptly notify the Depositor and the Holders (and, in the case of Book-Entry
Certificates, to the extent actually known to a Responsible Officer of the
Trustee or identified thereto by the Depository or the Depository Participants,
the Certificate Owners) of the Controlling Class that they may select a
Controlling Class Representative. Such notice shall set forth the process
established by the Trustee for selecting a Controlling Class Representative,
which process shall include the designation of the Controlling Class
Representative by the Majority Controlling Class Certificateholder(s) by a
writing delivered to the Trustee. No appointment of any Person as a successor
Controlling Class Representative shall be effective until such Person provides
the Trustee with (i) written confirmation of its acceptance of such appointment,
(ii) written confirmation of its agreement to keep confidential, for so long as
reports are required to be filed with respect to the Trust under Section 15(d)
of the Exchange Act, all information received by it with respect to the Trust
and its assets that has not been filed with the Commission, (iii) an address and
telecopy number for the delivery of notices and other correspondence and (iv) a
list of officers or employees of such Person with whom the parties to this
Agreement may deal (including their names, titles, work addresses and telecopy
numbers).

            (b) Within ten Business Days (or as soon thereafter as practicable
if the Controlling Class consists of Book-Entry Certificates) of any change in
the identity of the Controlling Class Representative of which a Responsible
Officer of the Trustee has actual knowledge and otherwise promptly upon request
from a Master Servicer or a Special Servicer, the Trustee shall deliver to each
of the Master Servicers and the Special Servicers the identity of the
Controlling Class Representative and a list of each Holder (or, in the case of
Book-Entry Certificates, to the extent actually known to a Responsible Officer
of the Trustee or identified thereto by the Depository or the Depository
Participants, each Certificate Owner) of the Controlling Class, including, in
each case, names and addresses. With respect to such information, the Trustee
shall be entitled to conclusively rely on information provided to it by the
Holders (or, in the case of Book-Entry Certificates, subject to Section 5.06, by
the Depository or the Certificate Owners) of such Certificates, and each of the
Master Servicers and the Special Servicers shall be entitled to rely on such
information provided by the Trustee with respect to any obligation or right
hereunder that the Master Servicers and the Special Servicers, as the case may
be, may have to deliver information or otherwise communicate with the
Controlling Class Representative or any of the Holders (or, if applicable,
Certificate Owners) of the Controlling Class. In addition to the foregoing,
within two Business Days of the selection, resignation or removal of a
Controlling Class Representative, the Trustee shall notify the other parties to
this Agreement of such event.

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

            (d) If the Great Lakes Crossing Mortgage Loan Group becomes
specially serviced in accordance with the terms of a Great Lakes Crossing
Servicing Agreement and, pursuant to the Great Lakes Crossing Intercreditor
Agreement, the Series 2003-CK2 Trustee or other holder of the Great Lakes
Crossing Companion Loan or its servicing agent notifies the Trustee or the
Master Servicer that the Trustee, as holder of the Great Lakes Crossing Mortgage
Loan, or its designee, is entitled to certain consultation rights with respect
to the Great Lakes Crossing Mortgage Loan or any Great Lakes Crossing REO
Mortgage Loan and/or forwards a copy of its "Asset Status Report" (as defined in
the Great Lakes Crossing Intercreditor Agreement) to the Trustee or the Master
Servicer, then the Trustee or the Master Servicer, as applicable, shall promptly
within one Business Day so notify, and shall forward the copy of such Asset
Status Report to, the Special Servicer and the Controlling Class Representative.
For so long as the Trustee or its designee is entitled to such consultation
rights under the terms of the Great Lakes Crossing Intercreditor Agreement, the
Trustee hereby delegates such consultation rights to the Special Servicer, who
shall exercise them in consultation with the Controlling Class Representative.

            In addition, if pursuant to the terms of the Great Lakes Crossing
Intercreditor Agreement, upon the occurrence of an event of default under the
Great Lakes Crossing Total Loan, the Trustee, as holder of the Great Lakes
Crossing Mortgage Loan, has the right to purchase the Great Lakes Crossing
Companion Loan at the price set forth in the Great Lakes Crossing Intercreditor
Agreement, then the Trustee shall promptly so notify all of the Controlling
Class Certificateholders. Any single Certificateholder or group of
Certificateholders entitled to a majority of the Voting Rights allocated to the
Controlling Class may indicate to the Trustee in writing its or their intent to
purchase the Great Lakes Crossing Companion Loan in accordance with Section 3.6
of the Great Lakes Crossing Intercreditor Agreement and/or any corresponding
provision of a Great Lakes Crossing Servicing Agreement, whereupon the Trustee
shall designate such Certificateholder or group of Certificateholders as its
designee to so purchase the Great Lakes Crossing Companion Loan, in its or their
individual capacity and not on behalf of the Trust, in accordance with such
Section 3.6 of the Great Lakes Crossing Intercreditor Agreement and/or any
corresponding provision of a Great Lakes Crossing Servicing Agreement. Any such
purchase will be subject to all applicable provisions of, and at the price set
forth in, the Great Lakes Crossing Intercreditor Agreement (including those
provisions that mandate who may be a permitted transferee of the Great Lakes
Crossing Companion Loan). Upon any such purchase, such Certificateholder or
group of Certificateholders shall constitute the "A-1 Noteholder" under the
Great Lakes Crossing Intercreditor Agreement, and the Great Lakes Crossing
Mortgage Loan shall be serviced and administered in accordance with Article XII
of this Agreement. The Trustee shall reasonably cooperate with such
Certificateholder or Certificateholders in effecting such purchase.

            (e) Once a Controlling Class Representative has been selected
pursuant to this Section 3.23, each of the parties to this Agreement and each
Certificateholder (or Certificate Owner, if applicable) shall be entitled to
rely on such selection unless a majority of the Holders (or, in the case of
Book-Entry Certificates, the Certificate Owners) of the Controlling Class, by
aggregate Certificate Principal Balance, or such Controlling Class
Representative, as applicable, shall have notified the Trustee and each other
party to this Agreement and each Holder (or, in the case of Book-Entry
Certificates, Certificate Owner) of the Controlling Class, in writing, of the
resignation or removal of such Controlling Class Representative.

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

            Section 3.24 Certain Rights and Powers of the Controlling Class
Representative

            (a) The applicable Special Servicer shall prepare a report (the
"Asset Status Report") recommending the taking of certain actions for each
Mortgage Loan that becomes a Specially Serviced Mortgage Loan and deliver such
Asset Status Report to the Controlling Class Representative and the applicable
Master Servicer not later than 45 days after the servicing of such Mortgage Loan
is transferred to such Special Servicer; provided, however, that with respect to
the 622 Third Avenue Loan and the Washington Center Loan, the applicable Special
Servicer shall prepare the Asset Status Report in accordance with Section 3.27.
If (i) after 10 Business Days from receipt of an Asset Status Report the
Controlling Class Representative does not object to such Asset Status Report or
(ii) within 10 Business Days after receipt of an Asset Status Report the
Controlling Class Representative objects to such Asset Status Report and the
applicable Special Servicer makes a determination in accordance with the
Servicing Standard that such objection is not in the best interest of all the
Certificateholders, the applicable Special Servicer shall take the recommended
actions described in the Asset Status Report. If within 10 Business Days after
receipt of an Asset Status Report the Controlling Class Representative objects
to such Asset Status Report and the applicable Special Servicer does not make a
determination in accordance with the Servicing Standard that such objection is
not in the best interest of all the Certificateholders, the Special Servicer
shall revise such Asset Status Report as soon as practicable thereafter, but in
no event later than 30 days after the objection to the Asset Status Report by
the Controlling Class Representative. The applicable Special Servicer shall
continue to revise the Asset Status Report until, as provided above, (i) the
Controlling Class Representative fails to object to the revised Asset Status
Report or (ii) the Controlling Class Representative objects to the revised Asset
Status Report and the applicable Special Servicer makes a determination in
accordance with the Servicing Standard that such objection is not in the best
interest of all the Certificateholders; provided, however, that if the
applicable Special Servicer has not taken the recommended actions described in
an Asset Status Report in accordance with this paragraph within 90 days of the
Controlling Class Representative's receipt of the initial Asset Status Report,
the applicable Special Servicer shall take the recommended actions described in
the most recent Asset Status Report submitted to the Controlling Class
Representative, which Asset Status Report shall be deemed to have been approved
by the Controlling Class Representative. If the applicable Special Servicer
makes a determination in accordance with the Servicing Standard that it should
take a materially different action than was previously approved in an Asset
Status Report, it shall submit a revised Asset Status Report setting forth its
proposed action in accordance with this Section 3.24(a),

            In addition, notwithstanding anything in any other Section of this
Agreement to the contrary (except in the case of the 622 Third Avenue Loan and
the Washington Center Loan in which case Section 3.27 shall control the
preparation of the Asset Status Report with respect to the related Mortgage Loan
and the actions the applicable Master Servicer and Special Servicer are
permitted to take with respect thereto), but in all cases subject to Section
3.24(b), the applicable Special Servicer will not be permitted to take, or
consent to the applicable Master Servicer's taking, any of the actions
identified in clauses (i) through (xi) of this sentence not otherwise
specifically covered by an approved Asset Status Report, unless and until the
applicable Special Servicer has notified the Controlling Class Representative in
writing of such Special Servicer's intent to take or permit the particular
action and the Controlling Class Representative has consented (or has failed to
object) thereto in writing within ten Business Days (or, in the case of any
consent to leasing activity at a Mortgaged Property securing a KeyBank Mortgage
Loan or NCBFSB Mortgage Loan as contemplated by clause (viii) below, 3 Business
Days) of having been notified thereof in writing and having been provided with
all reasonably requested information with respect thereto:

            (i) any foreclosure upon or comparable conversion (which may include
      acquisitions of an REO Property) of the ownership of the property or
      properties securing any Specially Serviced Mortgage Loan as comes into and
      continues in default;

            (ii) any modification, amendment or waiver of a monetary term
      (including a change in the timing of payments but excluding the waiver of
      Default Charges) or any material non-monetary term (excluding the waiver
      of any "due-on-sale" or "due-on-encumbrance" clause, which clauses are
      addressed in clause (ix) below) of (A) any Performing Mortgage Loan with a
      principal balance of $2,500,000 or more (or, if the proposed
      modification/waiver is an extension of maturity or a waiver of Post-ARD
      Additional Interest under the circumstances contemplated by Section
      3.20(f), any Performing Mortgage Loan without regard to balance) or (B)
      any Specially Serviced Mortgage Loan;

            (iii) any acceptance of a discounted payoff with respect to any
      Specially Serviced Mortgage Loan;

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

            (v) any release of real property collateral for any Mortgage Loan
      (other than in circumstances (A) involving a Performing Mortgage Loan with
      a principal balance of less than $2,500,000, (B) where the release of
      collateral is not conditioned on obtaining the consent of the lender under
      the related Mortgage Loan Documents (in which event the applicable Master
      Servicer or Special Servicer, as appropriate, shall notify the Controlling
      Class Representative in writing of such Master Servicer's or Special
      Servicer's, as the case may be, intent to take such action) or (C) set
      forth in Section 3.20(g)(iii), and other than upon satisfaction of the
      subject Mortgage Loan);

      the lender (in which event the applicable Master Servicer or Special
      Servicer, as appropriate, shall notify the Controlling Class
      Representative in writing of such Master Servicer's or Special Servicer's,
      as the case may be, intent to take such action));

      or replacement, of a property manager with respect to any Mortgaged
      Property securing a Mortgage Loan, any termination or change, or consent
      to the termination or change, of the franchise for any Mortgaged Property
      operated as a hospitality property, or any consent to leasing activity

      to taking such action, provide the Controlling Class Representative with
      written notice of such Master Servicer's intent to take such action, which
      notice shall describe the circumstances of such action, including all
      information necessary for the Controlling Class Representative to
      determine whether the NCBFSB Subordinate Debt Conditions have been
      satisfied));

            (x) with respect to any Mortgage Loan with a Stated Principal

      such Default Charges; provided that this clause (xi) shall not apply to
      the first such waiver with respect to any Mortgage Loan;

provided, that with respect to Performing Mortgage Loans, the 10 Business Days
(or, if applicable, three Business Days) within which the Controlling Class
Representative must object shall coincide with the Special Servicer's
10-Business Day (or, if applicable, the three-Business Day) period to object set
forth in Sections 3.03(d), 3.08, 3.20(a)(i), 3.20(f) and 3.20(h); and provided,
further, that, in the event that the applicable Special Servicer determines that
immediate action is necessary to protect the interests of the Certificateholders
(as a collective whole), the applicable Special Servicer may take any such
action without waiting for the Controlling Class Representative's response; and
provided, further, that the foregoing rights of the Controlling Class
Representative shall not relate to the Great Lakes Crossing Mortgage Loan or any
Great Lakes Crossing REO Property; provided, further, that the Special Servicer
shall notify the Controlling Class Representative (but shall not require the
consent or deemed consent thereof) with regard to any action identified in
clauses (v) through (vii) of this sentence that the Master Servicer or the

action.

            (b) Notwithstanding anything herein to the contrary: (i) no Special
Servicer shall have any right or obligation to consult with or to seek and/or
obtain consent or approval from any Controlling Class Representative prior to
acting, and the provisions of this Agreement requiring such shall be of no
effect, during the period prior to the initial selection of a Controlling Class
Representative and, if any Controlling Class Representative resigns or is
removed, during the period following any such resignation or removal of a
Controlling Class Representative until a replacement is selected; and (ii) no
advice, direction or objection from or by the Controlling Class Representative,
as contemplated by Section 3.24(a), may (and each Master Servicer and Special
Servicer shall ignore and act without regard to any such advice, direction or
objection that such Master Servicer or Special Servicer, as the case may be, has
determined, in its reasonable, good faith judgment, would) (A) require or cause

Servicer's responsibilities under this Agreement.

Representative may act solely in the interests of the Holders of the Controlling
Class; (iii) the Controlling Class Representative does not have any duties to

            Section 3.25 Replacement of Special Servicers

            (a) Subject to Section 3.25(b), the Controlling Class Representative
may, upon not less than ten days' prior written notice to the respective parties
hereto, remove the existing General Special Servicer hereunder (with or without
cause) or the existing Co-op Special Servicer upon the occurrence and
continuation of an Event of Default with respect to such Co-op Special Servicer
in accordance with the provisions of Section 7.01(b) and appoint a successor to
such Special Servicer; provided that, if any such removal is made without cause,
then the costs of transferring the special servicing responsibilities of the

Total Loan and the Washington Center Total Loan, the related Controlling Class
Representative may, at any time and from time to time, replace the General
Special Servicer then acting with respect to the related Mortgage Loan and
appoint a replacement Special Servicer in lieu thereof; provided that, if any
such removal is made without cause, then the costs of transferring the special
servicing responsibilities of the removed Special Servicer will be paid by the
Controlling Class Representative of the related Mortgage Loan.

            (b) No removal of a Special Servicer and/or appointment of a
successor thereto pursuant to Section 3.25(a) shall be effective until: (i) the
Trustee shall have received (A) written confirmation from each of the Rating
Agencies that such removal and/or appointment will not result in an Adverse
Rating Event with respect to any Class of Rated Certificates, (B) an
Acknowledgment of Proposed Special Servicer in the form attached hereto as
Exhibit I-2, executed by the Person designated to be the successor to such
terminated Special Servicer, and (C) an Opinion of Counsel (which shall not be
an expense of the Trustee or the Trust) substantially to the effect that (1) the
removal of such terminated Special Servicer and/or the appointment of the Person
designated to serve as successor thereto is in compliance with this Section
3.25, (2) such designated Person is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, (3) the
Acknowledgment of Proposed Special Servicer, the form of which is attached
hereto as Exhibit I-2, has been duly authorized, executed and delivered by such
designated Person and (4) upon the execution and delivery of the Acknowledgment
of Proposed Special Servicer, such designated Person shall be bound by the terms
of this Agreement and, subject to customary bankruptcy and insolvency exceptions
and customary equity exceptions, this Agreement shall be enforceable against
such designated Person in accordance with its terms; and (ii) if such terminated
Special Servicer has been removed by the Controlling Class Representative
without cause, the Certificateholders of the Controlling Class have delivered to
the Trustee and the terminated Special Servicer such Certificateholders' joint
and several undertaking and, with respect to the 622 Third Avenue Loan or the
Washington Center Loan, the respective Controlling Class Representatives'
undertaking, to pay any expenses incurred by the Trustee and such terminated
Special Servicer in connection with the transfer of special servicing
responsibilities to a successor Special Servicer.

            (c) Any Special Servicer terminated pursuant to Section 3.25(a)
shall be deemed to have been so terminated simultaneously with the designated
successor's becoming a Special Servicer hereunder; provided that (i) the
terminated Special Servicer shall be entitled to receive, in connection with its
termination, payment out of the Collection Accounts of all of its accrued and
unpaid Special Servicing Fees, as and to the extent provided in Section 3.05(a),
and reimbursement from the successor Special Servicer of all outstanding
Servicing Advances made by the terminated Special Servicer and all unpaid
Advance Interest accrued on such outstanding Servicing Advances (in which case
the successor Special Servicer shall be deemed to have made such Servicing
Advances at the same time that the terminated Special Servicer had actually made
them), (ii) the terminated Special Servicer shall thereafter be entitled to
Workout Fees, as and to the extent expressly permitted by Section 3.11(c), and
(iii) such terminated Special Servicer shall continue to be entitled to the
benefits of Section 6.03, notwithstanding any such termination; and provided,
further, that the terminated Special Servicer shall continue to be obligated to
pay (and entitled to receive) all other amounts accrued to (or owing by) it
under this Agreement on or prior to the effective date of such termination. Such
terminated Special Servicer shall cooperate with the Trustee and the replacement
Special Servicer in effecting the transfer of the terminated Special Servicer's
responsibilities and rights hereunder to its successor, including the transfer
within two Business Days of its termination becoming effective pursuant to
Section 3.25, to the replacement Special Servicer for administration by it of
all cash amounts that at the time are or should have been credited by the
terminated Special Servicer to the REO Account or to any Servicing Account or
Reserve Account or should have been delivered to the Master Servicer or that are
thereafter received by or on behalf of the terminated Special Servicer with
respect to any Mortgage Loan or REO Property.

            Section 3.26 Application of Default Charges

            (a) Any and all Default Charges that are actually received by or on
behalf of the Trust with respect to any Mortgage Loan or REO Mortgage Loan,
shall be applied for the following purposes and in the following order, in each
case to the extent of the remaining portion of such Default Charges:

            first, to pay to any Fiscal Agent, the Trustee, the Master Servicers
or the Special Servicers, in that order, any Advance Interest due and owing to
such party on outstanding Advances made thereby with respect to such Mortgage
Loan or REO Mortgage Loan, as the case may be;

            second, to reimburse the Trust for any Advance Interest paid to any
Fiscal Agent, the Trustee, the Master Servicers or the Special Servicers since
the Closing Date with respect to such Mortgage Loan or REO Mortgage Loan, as the
case may be, which interest was paid from a source other than Default Charges
collected on such Mortgage Loan or REO Mortgage Loan, as the case may be;

            third, to pay any outstanding expense incurred by the applicable
Special Servicer in connection with inspecting the related Mortgaged Property or
REO Property, as applicable, pursuant to Section 3.12;

            fourth, to reimburse the Trust for any expenses reimbursed to the
applicable Special Servicer since the Closing Date in connection with inspecting
the related Mortgaged Property or REO Property, as applicable, pursuant to
Section 3.12, which expenses were previously paid from a source other than
Default Charges collected on such Mortgage Loan or REO Mortgage Loan, as the
case may be;

            fifth, to pay the appropriate party for any other outstanding
expense (exclusive of Special Servicing Fees, Workout Fees and Liquidation Fees)
incurred thereby with respect to such Mortgage Loan or REO Mortgage Loan, as the
case may be, which expense, if not paid out of Default Charges collected on such
Mortgage Loan or REO Mortgage Loan, as the case may be, will likely become an
Additional Trust Fund Expense;

            sixth, to reimburse the Trust for any other Additional Trust Fund
Expense (exclusive of Special Servicing Fees, Workout Fees and Liquidation Fees)
paid to the appropriate party since the Closing Date with respect to such
Mortgage Loan or REO Mortgage Loan, as the case may be, which Additional Trust
Fund Expense was paid from a source other than Default Charges collected on such
Mortgage Loan or REO Mortgage Loan, as the case may be; and

            seventh, to pay any remaining portion of such Default Charges as
Additional Master Servicing Compensation to the applicable Master Servicer, if
such Default Charges were collected when the loan was a Performing Mortgage
Loan, and otherwise to pay any remaining portion of such Default Charges as
Additional Special Servicing Compensation to the applicable Special Servicer.

            (b) Default Charges applied to reimburse the Trust pursuant to any
of clause second, clause fourth or clause sixth of Section 3.26(a) are intended
to be available for distribution on the Certificates pursuant to Section 4.01(a)
and Section 4.01(b), subject to application pursuant to Section 3.05(a) or
3.05(b) for any items payable out of general collections on the Mortgage Pool.
Default Charges applied to reimburse the Trust pursuant to any of clause second,
clause fourth or clause sixth of Section 3.26(a) shall be deemed to offset
payments of Advance Interest, costs of property inspections or, except for
Special Servicing Fees, Workout Fees and Liquidation Fees, other Additional
Trust Fund Expenses (depending on which clause is applicable) in the
chronological order in which they were made or incurred with respect to the
subject Mortgage Loan or REO Mortgage Loan (whereupon such Advance Interest,
costs of property inspections or, except for Special Servicing Fees, Workout
Fees and Liquidation Fees, other Additional Trust Fund Expenses (depending on
which clause is applicable) shall thereafter be deemed to have been paid out of
Default Charges).

            Section 3.27 Rights of the Holder of the 622 Third Avenue B Loan and
the Holders of the Washington Center Junior Loans

            (a) [Intentionally Oomitted]

            (b) With respect to the 622 Third Avenue Loan and the Washington
Center Loan, pursuant to the related A/B Intercreditor Agreement, the Special
Servicer shall prepare an Asset Status Report recommending the taking of certain
actions for the related Mortgage Loan when such Mortgage Loan becomes a
Specially Serviced Mortgage Loan and deliver such Asset Status Report to the
Controlling Class Representative (and, in the case of the Washington Center
Loan, the other Washington Center Junior Holder, if any) not later than 30 days
after the servicing of the related Mortgage Loan is transferred to the
applicable Special Servicer. Such Asset Status Report shall contain language on
the cover page substantially similar to the language set forth on Schedule 3 to
the related A/B Intercreditor Agreement. If within 10 Business Days after
receipt of an Asset Status Report the Controlling Class Representative objects
to such Asset Status Report, the Special Servicer shall revise such Asset Status
Report as soon as practicable thereafter, but in no event later than 30 days
after the objection to the Asset Status Report by the Controlling Class
Representative. With respect to the Washington Center Total Loan, the related B
Loan Holder (if not then the Controlling Holder) shall have 10 Business Days
after receipt of the Asset Status Report during which to consult with the
applicable Special Servicer on any action outlined in such Asset Status Report.
If within 10 Business Days after receipt of an Asset Status Report the
Controlling Class Representative neither objects nor affirmatively approves of
such Asset Status Report, the action outlined in such Asset Status Report shall
be deemed approved by the Controlling Class Representative and the applicable
Special Servicer shall deliver a notice to the Controlling Class Representative
advising them that their consent is deemed approved. With respect to the
Washington Center Total Loan, the other Washington Center Junior Holder shall
also receive notice from the applicable Special Servicer stating that it is
taking the actions outlined in the Asset Status Report. The applicable Special
Servicer shall continue to revise the Asset Status Report (in the case of the
Washington Center Total Loan, with copies thereof sent to the other Washington
Center Junior Holder) until, as provided above, the Controlling Class
Representative fails to object to the revised Asset Status Report; provided,
however, that if the applicable Special Servicer has not taken the recommended
actions described in an Asset Status Report in accordance with this paragraph
within 90 days of the Controlling Class Representative's receipt of the initial
Asset Status Report, the applicable Special Servicer shall take the recommended
actions described in the most recent Asset Status Report approved or deemed to
have been approved by the Controlling Class Representative. Notwithstanding the
foregoing, if the applicable Special Servicer makes a determination in
accordance with the Servicing Standard that such failure to take any action
recommended in an Asset Status Report, or the taking of any alternate action
recommended by the Controlling Class Representative or, in the case of the
Washington Center Total Loan, the other Washington Center Junior Holder, is not
in the best interest of the Certificateholders and any related the B Loan Holder
(with respect to the related A Loan) or Washington Center Junior Holder (with
respect to the Washington Center Loan), as applicable, as a collective whole
(taking into account the subordination of the B Loans, to the respective A Loans
and, in the case of the Washington Center Total Loan, the subordination of the C
Loan to the B Loan), then the applicable Special Servicer shall take the action
recommended by the then-current Asset Status Report.

            With respect to the Washington Center Total Loan and the 622 Third
Avenue Loan, the applicable Master Servicer or Special Servicer shall not be
permitted to take, or consent to the applicable Master Servicer's or Special
Servicer's, as the case may be, taking, any of the actions identified in clauses
(i) through (xiv) of this sentence not otherwise specifically covered by an
approved Asset Status Report, unless and until the applicable Master Servicer or
Special Servicer has notified the Controlling Class Representative and, in the
case of the Washington Center Total Loan, the other Washington Center Junior
Holder in writing of such Master Servicer's or Special Servicer's intent to take
or permit the particular action and the Controlling Class Representative has
consented (or has failed to object) thereto in writing within ten (10) Business
Days of having been notified thereof in writing and having been provided with
all reasonably requested information with respect thereto:

            (i) any acceleration of the related Mortgage Loan (unless such
      acceleration is, by its terms, automatic under the Mortgage Loan
      Documents) or any foreclosure upon or comparable conversion (which may
      include acquisitions of an REO Property) of the ownership of the property
      or properties securing any Specially Serviced Mortgage Loan as comes into
      and continues in default;

            (ii) any modification, amendment or waiver of a monetary term
      (including a change in the timing of payments but excluding the waiver of
      Default Charges, which is covered by clause (xiv) below) or any material
      non-monetary term (excluding the waiver of any "due-on-sale" or
      "due-on-encumbrance" clause, which clauses are addressed in clause (ix)
      below) of the related Mortgage Loan;

            (iii) any acceptance of a discounted payoff with respect to the
      related Mortgage Loan;

            (iv) any determination to bring an REO Property into compliance with
      applicable environmental laws;

            (v) any release of collateral for the related Mortgage Loan, other
      than upon satisfaction of such Mortgage Loan;

            (vi) any acceptance of substitute or additional collateral for the
      related Mortgage Loan;

            (vii) any releases of reserve funds or related letters of credit or
      adjustment to the amounts of reserve funds required under the related
      Mortgage Loan Documents with respect to the related Mortgaged Property;

            (viii) any termination or replacement, or consent to the termination
      or replacement, of the property manager with respect to the related
      Mortgaged Property;

            (ix) any waiver of a "due-on-sale" or "due-on-encumbrance" clause in
      the related Mortgage Loan;

            (x) any execution, termination, renewal or material modification of
      any material lease, to the extent lender's approval is provided for under
      the related Mortgage Loan Documents;

            (xi) any approval of an annual budget of the related Borrower, to
      the extent lender's approval is provided for under the related Mortgage
      Loan Documents and with respect to the Washington Center Loan, any
      approval by the lender of any waiver or suspension of "FF&E Reserve" (as
      such term is defined in the Mortgage Loan Documents) deposits;

            (xii) any waiver or modification of insurance requirements under the
      related Mortgage Loan Documents;

            (xiii) any proposed transfer or sale of the related Mortgaged
      Property or assumption of the related Mortgage Loan; and

            (xiv) any waiver of Default Charges where there is no Additional
      Master Servicing Compensation or Additional Special Servicing Compensation
      to offset the outstanding interest on Advances, property inspection costs
      or other Costs with respect to the related Mortgage Loan that would
      otherwise be offset by such Default Charge;

provided, that, in the event that the applicable Master Servicer or Special
Servicer determines that immediate action is necessary to protect the interests
of the Certificateholders, the 622 Third Avenue B Loan Holder or the Washington
Center Junior Holders, as applicable, as a collective whole (taking into account
the subordination of the 622 Third Avenue B Loan to the 622 Third Avenue Loan
and the subordination of the Washington Center C Loan to the Washington Center B
Loan and the Washington Center Junior Loans to the Washington Center Loan), the
applicable Master Servicer or Special Servicer may take any such action without
waiting for the Controlling Class Representative's response.

            The B Loan Holder and the Washington Center Junior Holders have
agreed pursuant to the related A/B Intercreditor Agreement that they will
provide the Master Servicer or the related Special Servicer, as applicable, with
its consent or objection to any proposed actions pursuant to this Section
3.27(b) within ten (10) Business Days after its receipt of any such proposal and
any back up materials and shall be deemed to have approved of such action if no
response is received within such ten (10) Business Days.

            Notwithstanding anything to the contrary contained in this Section
3.27(b), no advice, direction or objection from or by the Controlling Class
Representative of the Washington Center Loan, may (and the applicable Master
Servicer or Special Servicer, as the case may be, shall ignore and act without
regard to any such advice, direction or objection that the applicable Master
Servicer or Special Servicer has determined, in its reasonable, good faith
judgment, will) require or cause the applicable Master Servicer or Special
Servicer to take any action or refrain from taking any action that would violate
applicable law, any provision of the related A/B Intercreditor Agreement or this
Agreement or the terms of the related loan documents, including the obligation
to act in accordance with the Servicing Standard or the REMIC Provisions.

      to the entire principal balance of the 622 Third Avenue Non-Pooled Portion
      after the application of the 622 Principal Distribution Amount to the 622
      Third Avenue Pooled Portion pursuant to clause (a)(iii)(C) above, in each
      case, until the principal balance of the 622 Third Avenue Non-Pooled
      Portion has been reduced to zero;

            (viii) eighth, to reimburse the 622 Third Avenue Non-Pooled Portion
      in the amount of any prior 622 Third Avenue Collateral Support Deficits
      previously allocated to the Class 622 Participation Certificates pursuant
      to Section 4.04(e) hereof;

            (ix) ninth, any Yield Maintenance Charge in connection with a
      prepayment of the 622 Third Avenue Loan will be paid to the 622 Third
      Avenue Pooled Portion and the 622 Third Avenue Non-Pooled Portion on a pro
      rata basis (based on the amount of such prepayment allocated to reduce the
      Stated Principal Balances of the 622 Third Avenue Pooled Portion and the
      622 Third Avenue Non-Pooled Portion);

            (x) tenth, to reimburse the Controlling Class Representative of the
      Class 622 Participation Certificates for any unreimbursed Cure Payments
      previously made pursuant to Section 3.28(c) hereof; and

            (xi) eleventh, any remaining amount, to the 622 Third Avenue Loan
      REMIC Residual Interest.

            Amounts distributable in respect of the 622 Third Avenue Pooled
Portion and the 622 Third Avenue Non-Pooled Portion in accordance with this
Section 3.28(a) shall be deemed distributable in respect of the 622 Third Avenue
Loan REMIC Regular Interest A and 622 Third Avenue Loan REMIC Regular Interest B
from the 622 Third Avenue Loan REMIC to the Lower-Tier REMIC pursuant to Section
4.01(k), and any amounts distributable in respect of the 622 Third Avenue Loan
REMIC Residual Interest shall be deemed distributed to the Grantor Trust portion
of the Trust Fund (pursuant to Section 4.01(k)).

            (b) Provided a Control Appraisal Event has occurred, and the
Controlling Class Representative of the Class 622 Participation Certificates is
the Controlling Class Representative with respect to the 622 Third Avenue Total
Loan, the Controlling Class Representative of the Class 622 Participation
Certificates shall have the right, by written notice to the Master Servicer and
Special Servicer (a "Class 622 Purchase Notice") delivered (i) during any 622
Third Avenue Cure Period for which the Holder of the 622 Third Avenue B Loan is
entitled to make a Cure Payment or (ii) at any time the 622 Third Avenue Loan is
a Specially Serviced Mortgage Loan, provided that the 622 Third Avenue Loan is
then in default or default with respect thereto is reasonably foreseeable, to
purchase the 622 Third Avenue Loan in whole but not in part at the Purchase
Price. Upon the delivery of the Class 622 Purchase Notice to the Master Servicer
and Special Servicer, the Master Servicer or Special Servicer, as applicable,
shall cause the Trust Fund to sell (and the Controlling Class Representative of
the Class 622 Participation Certificates shall purchase) the 622 Third Avenue
Loan at the Purchase Price, on a date (the "Class 622 Purchase Date") not less
than five (5) Business Days nor more than ten (10) Business Days after the date
of the Class 622 Purchase Notice, as shall be established by the Master Servicer
or Special Servicer, as applicable. The Purchase Price shall be calculated by
the Master Servicer or Special Servicer, as applicable, three (3) Business Days
prior to the Class 622 Purchase Date and shall, absent manifest error, be
binding upon the Controlling Class Representative of the Class 622 Participation
Certificates. Concurrently with the payment to the Trust Fund of the Purchase
Price, the Master Servicer or Special Servicer, as applicable, shall direct the
Trustee to execute at the sole cost and expense of the Controlling Class
Representative of the Class 622 Participation Certificates in favor of the
Controlling Class Representative of the Class 622 Participation Certificates
assignment documentation which will assign the 622 Third Avenue Loan and the
related Mortgage Loan Documents without recourse, representations or warranties.
The right of the Controlling Class Representative of the Class 622 Participation
Certificates to purchase the 622 Third Avenue Loan under clause (i) of the first
sentence of this paragraph shall automatically terminate upon the expiration of
the applicable cure period. The right of the Controlling Class Representative of
the Class 622 Participation Certificates to purchase the 622 Third Avenue Loan
under clause (ii) of the first sentence of this paragraph shall automatically
terminate upon a foreclosure sale, sale by power of sale or delivery of a deed
in lieu of foreclosure with respect to the related Mortgaged Property.

            (c) The Master Servicer or Special Servicer shall deliver to the
Controlling Class Representative of the 622 Third Avenue Total Loan notice of
any monetary or non monetary default with respect to the 622 Third Avenue Loan
promptly after a Servicing Officer of the Master Servicer or the Special
Servicer, as applicable, becomes aware of such default. Upon receipt of such
notice, the Controlling Class Representative of the 622 Third Avenue Total Loan
shall have the right to cure defaults with respect to the 622 Third Avenue Loan
within 5 Business Days of receipt of notice with respect to a monetary default
and within 30 days of receipt of notice with respect to a non monetary default
following the date of such notice (the "622 Third Avenue Cure Period");
provided, however, that no single Cure Event shall continue for a period of more
than 90 consecutive days. In the event that the Controlling Class Representative
of the 622 Third Avenue Total Loan elects to cure a default that can be cured by
making a Cure Payment, the such Controlling Class Representative shall make such
Cure Payment to the Master Servicer. The right of the Controlling Class
Representative of the 622 Third Avenue Total Loan to reimbursement of any Cure
Payment (including the reimbursement of a previous Advance made by the Master
Servicer or the Trustee) will be subordinate to the payment of all other amounts
due with respect to the 622 Third Avenue Loan. Notwithstanding the foregoing,
the making of a Cure Payment by the Controlling Class Representative of the 622
Third Avenue Total Loan shall not act as a waiver of any amounts due under the
Mortgage Loan Documents by the related borrower.

            (d) Subject to the terms and conditions of this Agreement, if the
Master Servicer or Special Servicer, as applicable, in connection with a workout
or proposed workout of the 622 Third Avenue Loan, modifies the terms thereof
such that (i) the Stated Principal Balance is decreased, (ii) the Mortgage Rate
is reduced, (iii) payments of interest or principal are waived, reduced or
deferred or (iv) any other adjustment is made to any of the terms of such loan,
all payments to the 622 Third Avenue Pooled Portion pursuant to Section 3.28(a)
shall be made as though such workout did not occur, with the payment terms of
the 622 Third Avenue Pooled Portion remaining the same as they are on the
Closing Date, and the 622 Third Avenue Non-Pooled Portion shall bear the full
economic effect of all waivers, reductions or deferrals of amounts due on such
loan attributable to such workout, before the 622 Third Avenue Pooled Portion is
exposed to such economic effect.

            Prior to entering into any modification of the 622 Third Avenue Loan
that would have any of the effects described in clauses (i) through (iii) of the
preceding paragraph, the Master Servicer or Special Servicer, as applicable,
shall provide the Controlling Class Representative of the Class 622
Participation Certificates with notice thereof and with all information that the
Master Servicer or Special Servicer, as applicable, considers material, but in
any case including a draft of the agreement, if any, that sets forth such
proposed modification.

            Section 3.29 Washington Center Purchase Option and Cure Rights

            (a) If a Washington Center Triggering Event of Default has occurred
and is continuing, then, upon written notice from the applicable Master Servicer
or Special Servicer (a "Repurchase Option Notice") of such occurrence (which
notice the applicable Master Servicer or Special Servicer shall promptly give to
the Washington Center Junior Holders), the Option Holder (as defined below)
shall have the right, by written notice to the applicable Master Servicer or
Special Servicer and the other Washington Center Junior Holder (unless the
principal balance of the related junior loan has been reduced to zero) (the
"Option Repurchase Notice"), at any time after the occurrence of the Washington
Center Triggering Event of Default and prior to the earliest to occur of (a) the
cure of the Washington Center Triggering Event of Default, (b) the consummation
of a foreclosure sale, sale by power of sale or delivery of a deed in lieu of
foreclosure with respect to the related Mortgaged Property and (c) the
modification of the Mortgage Loan Documents, to purchase the Washington Center
Loan (if the Washington Center B Loan Holder is the party exercising such
option) and the Washington Center Loan and Washington Center B Loan (if the
Washington Center C Loan Holder is the party exercising such option), as
applicable, at the Purchase Price. Upon the delivery of the Option Repurchase
Notice to the applicable Master Servicer or Special Servicer and either the
Washington Center B Loan Holder or the Washington Center C Loan Holder, as
applicable, the applicable Master Servicer or Special Servicer and either the
Washington Center B Loan Holder or the Washington Center C Loan Holder, as
applicable, shall sell (and the applicable Controlling Option Holder shall
purchase) the Washington Center Loan (if the Washington Center B Loan Holder is
the party exercising such option) or the Washington Center Loan and the
Washington Center B Loan (if the Washington Center C Loan Holder is the party
exercising such option), as applicable (free and clear of any sub-interests
therein) for the applicable Purchase Price, on a date (the "Washington Center
Repurchase Date") not less than five (5) Business Days nor more than ninety (90)
Business Days after the date of the latest Option Repurchase Notice, as shall be
established by the applicable Master Servicer or Special Servicer and reasonably
acceptable to the purchasing Option Holder. Unless the Option Holder's right to
purchase the Washington Center Loan or the Washington Center Loan and the
Washington Center B Loan, as applicable, has terminated upon delivery of the
Option Repurchase Notice, the Option Holder shall be obligated to purchase the
Washington Center Loan or the Washington Center Loan and the Washington Center B
Loan, as applicable, in accordance with the terms of this Agreement and the
related A/B Intercreditor Agreement. The Purchase Price shall be calculated by
the applicable Master Servicer three (3) Business Days prior to the Washington
Center Repurchase Date (and such calculation shall be accompanied by reasonably
detailed back-up documentation explaining how such price was determined) and
shall, absent manifest error, be binding upon the Option Holder. The applicable
Master Servicer shall provide the Washington Center Junior Holders with notice
(A) if the mezzanine lender has indicated its intent to exercise its purchase
option pursuant to the mezzanine intercreditor agreement, (B) if the mezzanine
lender consummates the purchase and (C) if the mezzanine lender subsequent to
indicating its intention to exercise its purchase option, fails to do so. If any
Washington Center Junior Holder shall have remitted the Purchase Price pursuant
to its exercise of the purchase option hereunder before the applicable Master
Servicer's or such Washington Center Junior Holder's receipt of notice of the
mezzanine lender's intention to exercise its purchase option, the applicable
Master Servicer shall refund the Purchase Price to the Washington Center Junior
Holder that remitted such funds in exercising such purchase option. If the
mezzanine lender shall subsequently fail to exercise its purchase option, such
circumstance shall not affect any Washington Center Junior Holder's right to
exercise its purchase option hereunder and under the related A/B Intercreditor
Agreement and each Washington Center Junior Holder's right to exercise the
purchase option shall be reinstated (it being understood that any Washington
Center Junior Holder shall, regardless of the circumstances involving the
mezzanine lender's failure to exercise its purchase option, have only the time
period specified in this paragraph to exercise its purchase option).

            The "Option Holder" shall mean, either the Washington Center C Loan
Holder or the Washington Center B Loan Holder; provided that in the event that
the Washington Center B Loan Holder delivers an Option Repurchase Notice, the
Washington Center C Loan Holder may, at any time after the Washington Center C
Loan Holder receives such Option Repurchase Notice, whether or not the
Washington Center B Loan Holder has remitted the Purchase Price, exercise the
purchase option by delivering the Option Repurchase Notice to both the
applicable Master Servicer or Special Servicer and the Washington Center B Loan
Holder and in such event the Washington Center B Loan Holder's purchase option
shall be extinguished unless the Washington Center C Loan Holder fails to
exercise its option within the time period specified in the previous paragraph
in which case the Washington Center B Loan Holder's purchase option shall be
reinstated.

            (b) If the Borrower defaults under the Mortgage Loan Documents, the
Curing Junior Holder (as defined below) shall have the right to cure such
default, within the applicable cure period given to the Borrower under the
Mortgage Loan Documents, upon the terms set forth in the following paragraph.
Any such cure shall be made at the sole cost and expense of the Curing Junior
Holder, and any amounts advanced on behalf of the Borrower to effect any such
cure shall be reimbursable to the Curing Junior Holder in accordance with the
related A/B Intercreditor Agreement.

            In the event any monetary default beyond applicable notice and grace
periods or non-monetary default beyond applicable notice and grace periods (of
which the applicable Master Servicer or Special Servicer has knowledge) shall
exist with respect to the Mortgage Loan, then, upon notice from the applicable
Master Servicer or Special Servicer (a "Cure Option Notice") of the occurrence
of such default beyond applicable notice and grace periods (which notice the
applicable Master Servicer or Special Servicer shall promptly give to the
Washington Center Junior Holders upon receipt of knowledge thereof), the Curing
Junior Holder shall have the right, exercisable by the Curing Junior Holder by
giving written notice of its intent to cure a default within five (5) Business
Days of receipt of the Cure Option Notice, to cure such default; provided, in
the event that the Curing Junior Holder has elected to cure any default, the
default must be cured by the Curing Junior Holder within, in the case of a
monetary default, five (5) Business Days of receipt of such Cure Option Notice
and, in the case of a non-monetary default, thirty (30) days of receipt of such
Cure Option Notice. In the event that the Curing Junior Holder elects to cure a
default that can be cured by the payment of money (each such payment, a "Cure
Payment"), the Curing Junior Holder shall make such Cure Payment as directed by
the applicable Master Servicer or Special Servicer and each such Cure Payment
shall include all actual costs, expenses, losses, obligations, damages,
penalties, and disbursements imposed on or incurred by (whether or not yet paid)
the applicable Master Servicer or Special Servicer and the Washington Center B
Loan Holder (if the Washington Center C Loan Holder is the Person exercising the
Cure Option) (including, without limitation, all unreimbursed Advances (without
regard to whether such Advance would be a Non-Recoverable Advance) and any
interest charged thereon, Default Charges and any unpaid Servicing Fees with
respect to the Mortgage Loan) during the period of time from the expiration of
the grace period under the Mortgage Loan until such Cure Payment is made or such
other cure is otherwise effected. The right of the Curing Junior Holder to
reimbursement of any Cure Payment shall be subordinate in all respects to the
rights of the applicable Master Servicer or Special Servicer and the Washington
Center B Loan Holder (if the Washington Center C Loan Holder is the Person
exercising the Cure Option) to distributions with respect to the Washington
Center Total Loan and to all amounts distributable to it. So long as a default
exists that is being cured by the Curing Junior Holder pursuant to this Section
3.29 and the cure period has not expired and the Curing Junior Holder is
permitted to cure under the terms of this Section 3.29, the applicable Master
Servicer or Special Servicer shall not treat such default as a default or an
event of default (i) for purposes of making distributions in accordance with the
post- default priorities set forth in Section 5 of the related A/B Intercreditor
Agreement; (ii) for purposes of accelerating the Washington Center Loan,
modifying, amending or waiving any provisions of the Washington Center Loan or
commencing proceedings for foreclosure or the taking of title by deed-in-lieu of
foreclosure or other similar legal proceedings with respect to the related
Mortgaged Property; or (iii) for purposes of treating the Washington Center Loan
as a Specially Serviced Mortgage Loan; provided that such limitations shall not
prevent the applicable Master Servicer or Special Servicer or the Trustee from
sending notices of the default to the Borrower or any related guarantor or
making demands on the related Borrower or any related guarantor or from
collecting default interest or late payment charges from the Borrower.
Notwithstanding anything to the contrary contained in this Section 3.29(b), (A)
the Curing Junior Holder's right to cure a monetary default or non-monetary
default shall be limited to nine Cure Events over the life of the Washington
Center Loan and (B) no single Cure Event may exceed three consecutive months.
"Cure Event" means the Curing Junior Holder's exercise of cure rights, whether
for one month or for consecutive months in the aggregate. Additional Cure Events
shall only be permitted with the consent of the Special Servicer with the
consent of the Controlling Class Representative.

            The applicable Master Servicer or Special Servicer shall provide the
Washington Center Junior Holders with notice (A) if the mezzanine lender has
indicated its intent to exercise its cure rights pursuant to the mezzanine
intercreditor agreement, (B) if the mezzanine lender consummates the cure and
(C) if the mezzanine lender subsequent to indicating its intention to exercise
its cure rights, fails to do so. If any Curing Junior Holder shall have remitted
any Cure Payment in respect of the Washington Center Loan before the applicable
Master Servicer's or such Curing Junior Holder's receipt of the mezzanine
lender's intention to exercise its cure rights, the applicable Master Servicer
or Special Servicer shall refund such Cure Payment to the Curing Junior Holder.
If the mezzanine lender shall subsequently fail to exercise its cure rights,
such circumstance shall not affect any Junior Holder's rights to exercise its
cure rights hereunder and under the related A/B Intercreditor Agreement and each
Junior Holder's right to exercise its cure rights shall be reinstated. If the
applicable Master Servicer or Special Servicer or any Washington Center Junior
Holder receives notice of the failure of the mezzanine lender or the other
Washington Center Junior Holder to exercise its cure rights during the time
period for which it is permitted to cure any default, the Curing Junior Holder
shall have an additional 5 Business Days from the time of receipt of such notice
to cure such default.

            The rights of the Curing Junior Holder to reimbursement for any
payments made by the Curing Junior Holder pursuant to the preceding paragraph
shall be subordinate in all respects to the rights of the applicable Master
Servicer or Special Servicer, and if applicable the Washington Center B Loan
Holder, to distributions with respect to the Washington Center Total Loan and to
all amounts distributable to it pursuant to any fees or other compensation,
indemnity payments or other amounts distributable to them pursuant to the
related A/B Intercreditor Agreement.

            "Curing Junior Holder" shall mean, either the Washington Center C
Loan Holder or the Washington Center B Loan Holder; provided that in the event
that the Washington Center B Loan Holder delivers a Cure Option Notice, the
Washington Center C Loan Holder may, at any time, exercise the Cure Option by
delivering the Cure Option Notice to both the applicable Master Servicer or
Special Servicer and the Washington Center B Loan Holder and in such event the
Washington Center B Loan Holder's Cure Option shall be extinguished unless the
Washington Center C Loan Holder fails to exercise its option within the time
period specified in the second preceding paragraph in which case the Washington
Center B Loan Holder's Cure Option shall be reinstated.

                                   ARTICLE IV

Certificates shall be allocated to the Class LA-4-1 and Class LA-4-2
Uncertificated Interests, pro rata based on interest accrued; the interest
distributed in respect of the Class A-5 Certificates shall be allocated to the
Class LA-5-1 and Class LA-5-2 Uncertificated Interests, pro rata based on
interest accrued; the interest distributed in respect of the Class D
Certificates shall be allocated to the Class LD-1 and Class LD-2 Uncertificated
Interests, pro rata based on interest accrued; the interest distributed in
respect of the Class E Certificates shall be allocated to the Class LE-1 and
Class LE-2 Uncertificated Interests, pro rata based on interest accrued; and the
interest distributed in respect of the Class F Certificates shall be allocated
to the Class LF-1 and Class LF-2 Uncertificated Interests, pro rata based on
interest accrued; and (ii) (other than with respect to the Class LY, Class
L622-A, Class L622-B, Class L622-C, Class L622-D, Class L622-E and Class L622-F
Uncertificated Interests) the amount of interest that will actually be
distributed in respect of such Uncertificated Lower-Tier Interest's
corresponding Related Component or Components. 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 Certificate and allocated pro rata to the Class
LA-1-1, Class LA-1-2 and Class LA-1-3 Uncertificated Interests, in the case of
the Class A-1 Certificates; to the Class LA-2-1, Class LA-2-2 and Class LA-2-3
Uncertificated Interests, in the case of the Class A-2 Certificates; to the
Class LA-3-1 and Class LA-3-2 Uncertificated Interests, in the case of the Class

in the case of the Class A-4 Certificates; to the Class LA-5-1 and Class LA-5-2
Uncertificated Interests, in the case of the Class A-5 Certificates; to the
Class LD-1 and Class LD-2 Uncertificated Interests, in the case of the Class D
Certificates; to the Class LE-1 and Class LE-2 Uncertificated Interests, in the
case of the Class E Certificates; and to the Class LF-1 and Class LF-2
Uncertificated Interests, in the case of the Class F Certificates based on their
respective Interest Shortfall Amounts and (ii) the Interest Shortfall Amount
allocated to the related Class A-X Component or Class A-SP Component and
attributable to such Uncertificated Lower-Tier Interest. The Class LY
Uncertificated Interest shall accrue interest and, on each Distribution Date,
shall be deemed to receive distributions of interest in an amount equal to the
interest accrued and the interest actually distributed in respect of the Class
A-Y Certificates (including any Interest Shortfall Amount with respect thereto).
Any amounts remaining in the Lower-Tier Distribution Account after payment to
the Uncertificated Lower-Tier Interests pursuant to this Section 4.01(c) and
Section 4.01(d) and payment of expenses of the Trust Fund shall be distributed
to the Class LR Certificates in respect of the residual interest in the
Lower-Tier REMIC.

            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 deemed to be deposited by the
Trustee in the Upper-Tier Distribution Account.

            As of any date, payments of principal in respect of the Mortgage
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 Class Principal 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;
provided that

            (i) the Lower-Tier Principal Amount of the Class LA-1-1
      Uncertificated Interest shall be the lesser of $127,000,000 and the excess

      Principal Balance of the Class E Certificates, in each case reduced by any
      Collateral Support Deficit allocated to the Class E Certificates, first,
      to the Class LE-1 Uncertificated Interest and then the Class LE-2
      Uncertificated Interest; and

            (viii) the Lower-Tier Principal Amount of the Class LF-1

      Collateral Support Deficit allocated to the Class F Certificates, first,
      to the Class LF-1 Uncertificated Interest and then the Class LF-2
      Uncertificated Interest. 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 (other than the Class LY Uncertificated
      Interest and the Class L622 Uncertificated Interests) will be the Weighted
      Average Net Mortgage Rate, with respect to the Class LY Uncertificated
      Interest will be the Class A-Y Pass-Through Rate and, with respect to each
      of the Class L622 Uncertificated Interests will be the Pass-Through Rate
      of their Related Certificates.

Certificates shall be attributed to the Uncertificated Lower-Tier Interests to
the extent of their Related Components, pro rata, based on interest accrued on
such Components. Interest Shortfall Amounts allocated to the Class A-Y
Certificates shall be attributed to the Class LY Uncertificated Interest. Any
amounts so allocated shall have the same seniority as interest payments due on
the Class A-X, Class A-Y and Class A-SP Certificates. Prepayment Interest
Shortfalls shall be allocated to each Class of Uncertificated Lower-Tier
Interests pro rata on the basis of their respective interest entitlements;
provided, that Prepayment Interest Shortfalls with respect to the 622 Third
Avenue Loan shall first be allocated to the Class L622 Uncertificated Interests
in reverse alphabetical order.

            (d) On each Master Servicer Remittance Date, the Master Servicers
shall remit to the Trustee all Prepayment Premiums and Yield Maintenance Charges
(other than with respect to Prepayment Premiums and Yield Maintenance Charges
allocated to the 622 Third Avenue Loan) for deposit in the Lower-Tier
Distribution Account for distribution to the Uncertificated Lower-Tier
Interests, and shall remit to the Trustee all Prepayment Premiums and Yield
Maintenance Charges with respect to the 622 Third Avenue Loan for deposit in the
622 Third Avenue Loan REMIC Distribution Account for distribution to the 622
Third Avenue Loan REMIC Regular Interests. On each Distribution Date, the
Trustee shall be deemed to withdraw from the 622 Third Avenue Loan REMIC
Distribution Account an amount equal to the Prepayment Premiums and Yield
Maintenance Charges actually collected on the 622 Third Avenue Loan or related
REO Mortgage Loan and shall be deemed to distribute such amounts to the 622
Third Avenue Loan REMIC Regular Interests in the manner specified in Section
3.28(a)(ix) hereof for deposit in the Lower-Tier Distribution Account. On each
Distribution Date, the Trustee shall be deemed to 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 Mortgage
Loans during the related Due Period (other than any Yield Maintenance Charges
and Prepayment Premiums that are allocated to the 622 Third Avenue Non-Pooled
Portion pursuant to Section 3.28(a)(ix) hereof) and shall be deemed to
distribute such amount to the Uncertificated Lower-Tier Interests (other than
the Class L622 Uncertificated Interests), pro rata in proportion to their
outstanding Lower-Tier Principal Amounts. Yield Maintenance Charges and
Prepayment Premiums that are allocated to the 622 Third Avenue Non-Pooled
Portion pursuant to Section 3.28(a)(ix) hereof shall be allocated to the Class
L622 Uncertificated Interests pro rata in proportion to their outstanding
principal balances.

            On each Distribution Date, the Trustee shall withdraw any amounts on
deposit in the Upper-Tier Distribution Account that represent Prepayment
Premiums and Yield Maintenance Charges (other than any Yield Maintenance Charges
and Prepayment Premiums that are allocated to the 622 Third Avenue Non-Pooled
Portion pursuant to Section 3.28(a)(ix) hereof) actually collected on Loans or
REO Mortgage Loans during the related Due Period and remitted in respect of the
Uncertificated Lower-Tier Interests pursuant to this 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 A-3, Class A-4, Class A-5, Class B, Class C, Class D, Class E,
      Class F, Class G and Class H 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 A-3, Class A-4, Class A-5, Class B, Class C, Class D, Class E, Class
      F, Class G, Class H, Class J, Class K, Class L, Class M, Class N, Class O
      and Class P Certificates on such Distribution Date, (b) 25% and (c) the
      total amount of Prepayment Premiums (other than any Prepayment Premiums
      that are allocated to the 622 Third Avenue Non-Pooled Portion pursuant to
      Section 3.28(a)(ix) hereof) collected during the related Due Period. If
      the Prepayment Premium relates to a Co-op Mortgage Loan, the Holders of
      the Class A-Y Certificates shall be entitled to 70% of the portion of the
      subject Prepayment Premium that remains after the distribution
      contemplated in the immediately preceding sentence. Any Prepayment
      Premiums collected during the related Due Period and remaining after the
      distributions contemplated in the prior two sentences 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 A-3, Class A-4, Class A-5, Class B, Class C, Class
      D, Class E, Class F, Class G and Class H 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 A-3, Class A-4, Class A-5, Class B, Class C, Class D,
      Class E, Class F, Class G, Class H, Class J, Class K, Class L, Class M,
      Class N, Class O and Class P 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 (other than any Yield Maintenance Charges that are allocated to
      the 622 Third Avenue Non-Pooled Portion pursuant to Section 3.28(a)(ix)
      hereof) collected on such Principal Prepayment during the related Due
      Period. If the Yield Maintenance Charge relates to a Co-op Mortgage Loan,
      the Holders of the Class A-Y Certificates shall be entitled to 60% of the
      portion of the subject Yield Maintenance Charge that remains after the
      distribution contemplated in the immediately preceding sentence. Any Yield
      Maintenance Charges collected during the related Due Period remaining
      after the distributions contemplated in the prior two sentences shall be
      distributed to the Holders of the Class A-X Certificates.

            Following the reduction of the Class Principal Balances of the Class
A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class B, Class C, Class D,
Class E, Class F, Class G and Class H Certificates to zero, the Trustee shall
distribute to the Class A-Y Certificates the requisite percentage of such
Prepayment Premiums and Yield Maintenance Charges actually received and remitted
in respect of Uncertificated Lower-Tier Interests as set forth in Section
4.01(d)(i) and (ii) during the related Due Period with respect to the Co-op
Mortgage Loans. All remaining Prepayment Premiums and Yield Maintenance Charges
that relate to Co-op Mortgage Loans and all Yield Maintenance Charges and
Prepayment Premiums that relate to Mortgage Loans other than Co-op Mortgage
Loans actually received during the related Due Period with respect to the
Mortgage Loans and remitted in respect of Uncertificated Lower-Tier Interests
pursuant to this Section 4.01(d) (other than Prepayment Premiums and Yield
Maintenance Charges that are allocated to the 622 Third Avenue Non-Pooled
Portion pursuant to Section 3.28(a)(ix) hereof) shall be distributed to the
Class A-X Certificates.

            For purposes of determining the portion of any Yield Maintenance
Charge that is distributable to the Holders of any Class of Yield Maintenance
Certificates on any Distribution Date, the relevant "Discount Rate" shall be the
same discount rate (exclusive of any applicable spread) used to calculate such
Yield Maintenance Charge, with such discount rate (exclusive of any applicable
spread) converted to a monthly equivalent rate (regardless of whether any
similar conversion occurred at the loan level). The relevant Discount Rate shall
be provided promptly by the applicable Master Servicer to the Trustee.

            (e) On any applicable Distribution Date, (i) the Trustee shall
withdraw from the Post-ARD Additional Interest Distribution Account any Post-ARD
Additional Interest collected in respect of the Mortgage Loans for such
Distribution Date and shall distribute such amount to the Class V Certificates;
and (ii) with respect to amounts on deposit in the Excess Liquidation Proceeds
Reserve Account, the Trustee shall distribute such amount to the
Certificateholders, in sequential order, after first being deemed to distribute
such amount from the Lower-Tier REMIC to the Upper-Tier REMIC in respect of the
Related Uncertificated Lower-Tier Interest, as reimbursement for previously
allocated Collateral Support Deficits and shall distribute all amounts remaining
in the Excess Liquidation Proceeds Reserve Account thereafter to the holders of
the Class LR Certificates.

            (f) All distributions made with respect to each Class on each
Distribution Date shall be allocated pro rata among the outstanding Certificates
of 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 record of the respective Class 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 Trustee with written wiring
instructions no later than the related Record Date (which wiring instructions
may be in the form of a standing order applicable to all subsequent Distribution
Dates) and 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 Trustee 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
Depositor, the Master Servicers, the Special Servicers, the Underwriters or the
Initial Purchaser shall have any responsibility therefor except as otherwise
provided by this Agreement or applicable law.

            (g) Except as otherwise provided in Section 9.01, whenever the
Trustee 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 Trustee shall, no
later than two Business Days following the related 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 Trustee 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 Trustee, 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
Trustee 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).

            (h) 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 11.05 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 Trustee 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.

            (i) 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 the most subordinate Class of
Certificates (other than the Class 622 Participation Certificates; provided,
that if such shortfalls occur with respect to the 622 Third Avenue Loan, such
shortfalls shall be allocated to the Class 622 Participation Certificates in
reverse sequential order and then to the next most subordinate Class of
Certificates then outstanding) then outstanding, until the Class Principal
Balance thereof is reduced to zero, and then shall be allocated to the next most
subordinate Class of Certificate then outstanding. Such shortfalls shall be
allocated to the Uncertificated Lower-Tier Interests and to the 622 Third Avenue
Loan REMIC Regular Interests in the same manner as Collateral Support Deficits.

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

            (k) All payments made on the 622 Third Avenue Loan REMIC or
subsequently acquired REO Property shall be deemed to be paid to the Lower-Tier
REMIC before payments are made to the holders of the Uncertificated Lower-Tier
Interests pursuant to Sections 4.01(c) or 4.01(d), and shall be treated as
principal, interest, Prepayment Premium or Yield Maintenance Charges, as the
case may be, based on these characterizations with respect to the 622 Third
Avenue Loan (or related REO Property), except where expressly noted and, in
addition, any payment of principal on or reduction in the 622 Third Avenue Loan
REMIC balance shall reduce the principal balances of the 622 Third Avenue Loan
REMIC Regular Interests; provided, that payments of principal in reduction of
the Stated Principal Balance of the 622 Third Avenue Loan shall be applied to
reduce the Stated Principal Balances of the 622 Third Avenue Pooled Portion and
the 622 Third Avenue Non-Pooled Portion as specified in Section 3.28. Any
payments on or with respect to the 622 Third Avenue Loan in excess of the
principal, interest, Prepayment Premium or Yield Maintenance Charges
distributable on the 622 Third Avenue Loan REMIC Regular Interests shall be
distributable to the Class LR Certificates in respect of the 622 Third Avenue
Loan REMIC Residual Interest. The interest rate of the 622 Third Avenue Loan
REMIC Regular Interest A and 622 Third Avenue Loan REMIC Regular Interest B
shall be the Net Mortgage Pass-Through Rate of the 622 Third Avenue Pooled
Portion and the 622 Third Avenue Non-Pooled Portion, respectively. Servicing
Fees, Primary Servicing Fees, the Trustee Fees and all other servicing
compensation with respect to the 622 Third Avenue Loan shall be deemed to be
paid by the 622 Third Avenue Loan REMIC.

            Section 4.02 Statements to Certificateholders; Certain Other Reports

            (a) Based solely on information provided to the Trustee by the
Master Servicers pursuant to Sections 3.12, 4.02(b) and 4.02(c), the Trustee
shall prepare (or cause to be prepared) and, on each Distribution Date, provide
or make available electronically (or, upon request, by first class mail) to each
Privileged Person a statement substantially in the form of, and containing the
information set forth in, Exhibit E-1 hereto (the "Trustee Report"), detailing
the distributions on such Distribution Date and the performance, both in the
aggregate and individually to the extent available, of the Mortgage Loans and
the Mortgaged Properties; provided that the Trustee need not deliver to any
Privileged Person any Trustee Report that has been made available to such Person
via the Trustee's internet website as provided below; and provided, further,
that the Trustee has no affirmative obligation to discover the identities of
Certificate Owners and need only react to Persons claiming to be Certificate
Owners in accordance with Section 5.06; and provided, further, that during any
period that reports are required to be filed with the Commission with respect to
the Trust pursuant to Section 15(d) of the Exchange Act, each recipient of the
Trustee Report shall be deemed to have agreed to keep confidential the
information therein until such Trustee Report is filed with the Commission.

            On each Distribution Date, the Trustee shall provide or make
available electronically (or, upon request, by first class mail) to each
Privileged Person each file and report comprising the CMSA Investor Reporting
Package and any other report at the direction of the Depositor, to the extent
received by the Trustee since the prior Distribution Date (or, in the case of
the initial Distribution Date, since the Closing Date); provided that during any
period that reports are required to be filed with the Commission with respect to
the Trust pursuant to Section 15(d) of the Exchange Act, each recipient of such
files and reports shall be deemed to have agreed to keep confidential the
information in any such file or report until such particular file or report is
filed with the Commission.

            The Trustee shall have no obligation to provide the information or
reports described in this Section 4.02(a) until it has received the requisite
information or reports from the Master Servicers provided for herein, and the
Trustee shall not be in default hereunder due to a delay in providing the
Certificateholder Reports caused by a Master Servicer's or Special Servicer's
failure to timely deliver any information or reports hereunder. None of the
Master Servicers, the Special Servicers or the Trustee shall be responsible for
the accuracy or completeness of any information supplied to it by a Borrower,
each other or a third party, and accepted by it in good faith, that is included
in any reports, statements, materials or information prepared or provided by
either Master Servicer, either Special Servicer or the Trustee, as applicable.
None of the Trustee, the Master Servicers or the Special Servicers shall have
any obligation to verify the accuracy or completeness of any information
provided by a Borrower, a third party or each other.

            The Trustee shall make available each month, to the general public,
the related Trustee Report via its internet website initially located at
"www.ctslink.com/cmbs". In addition, the Trustee shall make available each
month, via its internet website on a restricted basis solely to Privileged
Persons, (i) the Unrestricted Servicer Reports, (ii) the CMSA Bond Level File
and the CMSA Collateral Summary File, (iii) any other report at the direction of
the Depositor and (iv) as a convenience to the general public (and not in
furtherance of the distribution thereof under the securities laws), the
Prospectus and this Agreement. Upon notification by the Depositor that CSFB LLC
has sold the Non-Registered Certificates to unaffiliated third parties, the
Trustee shall remove the restriction provided for in the preceding sentence and
shall make such reports and documents available to the general public. The
Trustee shall also make available each month, on a restricted basis to any
Privileged Person via its internet website, (i) the Restricted Servicer Reports,
and (ii) any other report at the direction of the Depositor. During any period
that reports are required to be filed with the Commission with respect to the
Trust pursuant to Section 15(d) of the Exchange Act, each recipient of such
files and reports shall be deemed to have agreed to keep confidential any such
information that has not been filed with the Commission.

            The Trustee makes no representations or warranties as to the
accuracy or completeness or any report, document or other information made
available on its internet website and assumes no responsibility therefor. In
addition, the Trustee may disclaim responsibility for any information
distributed by the Trustee for which it is not the original source.

            In connection with providing access to the Trustee's internet
website, the Trustee may require registration and the acceptance of a
disclaimer. The Trustee shall not be liable for the dissemination of information
in accordance herewith. Questions regarding the Trustee's internet website can
be directed to the Trustee's CMBS customer service desk at (301) 815-6600 or
such other number as the Trustee may hereinafter specify.

            The Trustee shall be entitled to rely on but shall not be
responsible for the content or accuracy of any information provided by third
parties for purposes of preparing the Trustee Report and may affix thereto any
disclaimer it deems appropriate in its reasonable discretion (without suggesting
liability on the part of any other party hereto).

            Notwithstanding the foregoing, the failure of a Master Servicer or
Special Servicer to disclose any information otherwise required to be disclosed
pursuant to this Section 4.02(a) or Section 4.02(b) shall not constitute a
breach of this Section 4.02(a) or Section 4.02(b) to the extent such Master
Servicer or such Special Servicer, as the case may be, so fails because such
disclosure, in the reasonable belief of such Master Servicer or such Special
Servicer, as the case may be, would violate any applicable law or any provision
of a Mortgage Loan Document prohibiting disclosure of information with respect
to the Mortgage Loans or the Mortgaged Properties, would constitute a waiver of
the attorney-client privilege on behalf of the Trust or would otherwise
materially harm the Trust Fund. A Master Servicer or a Special Servicer may
affix to any information provided by it any disclaimer it deems appropriate in
its reasonable discretion (without suggesting liability on the part of any other
party hereto).

            (b) Within a reasonable period of time after the end of each
calendar year, the Trustee shall prepare, or cause to be prepared, and mail to
each Person who at any time during the calendar year was a Certificateholder (i)
a statement containing the aggregate information set forth on page 2 of Exhibit
E-1 hereto for such calendar year or applicable portion thereof during which
such person was a Certificateholder and (ii) such other customary information as
the Trustee deems necessary or desirable for Certificateholders to prepare their
federal, state and local income tax returns, including the amount of original
issue discount accrued on the Certificates, if applicable. The obligations of
the Trustee in the immediately preceding sentence shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Trustee pursuant to any requirements of the Code. As soon as
practicable following the request of any Certificateholder in writing, the
Trustee shall furnish to such Certificateholder such information regarding the
Mortgage Loans and the Mortgaged Properties as such Certificateholder may
reasonably request and, as has been furnished to, or may otherwise be in the
possession of, the Trustee. Each Master Servicer and each Special Servicer shall
promptly provide to the Depositor and the Trustee such information regarding the
Mortgage Loans for which it acts as Master Servicer or Special Servicer and the
related Mortgaged Properties as such party may reasonably request and that has
been furnished to, or may otherwise be in the possession of, such Master
Servicer or such Special Servicer, as the case may be.

            Section 4.03 P&I Advances

            (a) On or before 1:00 p.m., New York City time, on each P&I Advance
Date, each Master Servicer shall, subject to Section 4.03(c), either (i) remit
from its own funds to the Trustee for deposit into the Lower-Tier Distribution
Account or the 622 Third Avenue Loan REMIC Distribution Account, as applicable,
an amount equal to the aggregate amount of P&I Advances, if any, to be made by
such Master Servicer in respect of the related Distribution Date, (ii) apply
amounts held in its Collection Account for future distribution to
Certificateholders in subsequent months in discharge of any such obligation to
make P&I Advances, 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 by such
Master Servicer. Any amounts held in a Collection Account for future
distribution and so used to make P&I Advances shall be appropriately reflected
in the applicable Master Servicer's records and replaced by the applicable
Master Servicer by deposit in such Collection Account prior to the next
succeeding Master Servicer Remittance Date (to the extent not previously
replaced through the deposit of Late Collections of the delinquent principal and
interest in respect of which such P&I Advances were made). If, as of 3:30 p.m.,
New York City time, on any P&I Advance Date, a Master Servicer shall not have
made any P&I Advance required to be made by it on such date pursuant to this
Section 4.03(a) (and shall not have delivered to the Trustee the Officer's
Certificate and other documentation related to a determination of
nonrecoverability of a P&I Advance pursuant to Section 4.03(c)) or shall not
have remitted any portion of the Master Servicer Remittance Amount required to
be remitted by such Master Servicer on such date, then the Trustee shall provide
notice of such failure to such Master Servicer by facsimile transmission as soon
as possible, but in any event before 4:30 p.m., New York City time, on such P&I
Advance Date. If after such notice the Trustee does not receive the full amount
of such P&I Advances by 6:00 p.m., New York City time, on such P&I Advance Date,
then the Trustee (or any Fiscal Agent on its behalf) shall (not later than 12:00
noon, New York City time, on the related Distribution Date) make the portion of
such P&I Advances that was required to be, but was not, made or remitted, as the
case may be, by such Master Servicer with respect to the related Distribution
Date, provided that no Master Servicer, Special Servicer, the Trustee or any
Fiscal Agent shall be required to make any P&I Advance with respect to any B
Loan.

            (b) The aggregate amount of P&I Advances to be made by each Master
Servicer in respect of any Distribution Date, subject to Section 4.03(c) below,
shall equal the aggregate of all Monthly Payments (other than Balloon Payments)
and any Assumed Monthly Payments, in each case net of any related Master
Servicing Fees, due or deemed due, as the case may be, in respect of the
Mortgage Loans (including Balloon Mortgage Loans delinquent as to their
respective Balloon Payments) as to which such Master Servicer is the applicable
Master Servicer and any successor REO Mortgage Loans on their respective Due
Dates during the related Collection Period, in each case to the extent such
amount was not paid by or on behalf of the related Borrower or otherwise
collected by or on behalf of the Trust as of the close of business on the
related Determination Date; provided that, if an Appraisal Reduction Amount
exists with respect to any Required Appraisal Loan, then the interest portion of
any P&I Advance required to be made in respect of such Required Appraisal Loan
for the related Distribution Date shall be reduced (it being herein acknowledged
that there shall be no reduction in the principal portion of such P&I Advance)
to equal the product of (i) the amount of the interest portion of such P&I
Advance that would otherwise be required to be made in respect of such Required
Appraisal Loan for such Distribution Date without regard to this proviso,
multiplied by (ii) a fraction, expressed as a percentage, the numerator of which
shall equal the Stated Principal Balance of such Required Appraisal Loan
immediately prior to such Distribution Date, net of the related Appraisal
Reduction Amount, and the denominator of which shall equal the Stated Principal
Balance of such Required Appraisal Loan immediately prior to such Distribution
Date.

            (c) Notwithstanding anything herein to the contrary, no P&I Advance
shall be required to be made hereunder if such P&I Advance would, if made,
constitute a Nonrecoverable P&I Advance. The determination by a Master Servicer
(or, if applicable, the Trustee or any Fiscal Agent) that it has made a
Nonrecoverable P&I Advance or that any proposed P&I Advance, if made, would
constitute a Nonrecoverable P&I Advance, shall be made by such Person in its
reasonable judgment and shall be evidenced by an Officer's Certificate delivered
to the Depositor, to the applicable Special Servicer, to the Controlling Class
Representative and, if made by such Master Servicer, to the Trustee (on or
before the related P&I Advance Date in the case of a proposed P&I Advance),
setting forth the basis for such determination, accompanied by a copy of an
Appraisal of the related Mortgaged Property or REO Property performed within the
12 months preceding such determination by a Qualified Appraiser, and further
accompanied by any other information, including engineers' reports,
environmental surveys or similar reports, that the Person making such
determination may have obtained and that support such determination. The Trustee
and any Fiscal Agent shall be entitled to conclusively rely on any
nonrecoverability determination made by a Master Servicer with respect to a
particular P&I Advance. The applicable Special Servicer shall promptly furnish
any party required to make P&I Advances hereunder with any information in its
possession regarding the Specially Serviced Mortgage Loans and REO Properties as
such party required to make P&I Advances may reasonably request.

            (d) Each Master Servicer, the Trustee and any Fiscal Agent shall
each be entitled to receive interest at the Reimbursement Rate in effect from
time to time, accrued on the amount of each P&I Advance made thereby (with its
own funds), for so long as such P&I Advance is outstanding (or, if such P&I
Advance was made prior to the end of any grace period applicable to the subject
delinquent Monthly Payment, for so long as such P&I Advance is outstanding
following the end of such grace period). Such interest with respect to any P&I
Advance shall be payable: (i) first, in accordance with Sections 3.05 and 3.26,
out of any Default Charges subsequently collected on the particular Mortgage
Loan or REO Mortgage Loan as to which such P&I Advance relates; and (ii) then,
after such P&I Advance is reimbursed, but only if and to the extent that such
Default Charges are insufficient to cover such Advance Interest, out of general
collections on the Mortgage Loans and REO Properties on deposit in the
Collection Account. Each Master Servicer shall reimburse itself, the Trustee or
any Fiscal Agent, as applicable, for any outstanding P&I Advance made thereby
with respect to any Mortgage Loan or REO Mortgage Loan as soon as practicable
after funds available for such purpose are deposited in the Collection Account,
and in no event shall interest accrue in accordance with this Section 4.03(d) on
any P&I Advance as to which the corresponding Late Collection was received by or
on behalf of the Trust as of the related P&I Advance Date. No Master Servicer
shall be entitled to Advance Interest on any particular P&I Advance made thereby
to the extent a payment is received but is being held by or on behalf of such
Master Servicer in suspense.

            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, the Trustee
shall calculate the amount, if any, by which (i) the aggregate Stated Principal
Balance of the Mortgage Loans (excluding the 622 Third Avenue Non-Pooled
Portion) and any REO Mortgage Loans (excluding the 622 Third Avenue Non-Pooled
Portion) expected to be outstanding immediately following such Distribution Date
is less than (ii) the then aggregate Class Principal Balance of the Principal
Balance Certificates (other than the Class 622 Third Avenue Participation
Certificates) after giving effect to distributions of principal on such
Distribution Date (any such deficit, the "Collateral Support Deficit"). Any
allocation of Collateral Support Deficit to a Class of Principal Balance
Certificates (other than the Class 622 Third Avenue Participation Certificates)
shall be made by reducing the Class Principal Balance thereof by the amount so
allocated. Any Collateral Support Deficit allocated to a Class of Principal
Balance 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 Class Principal Balance of the Class of Certificates in respect
of which any such reimbursement is made.

            (b) On each Distribution Date, the Class Principal Balances of the
Principal Balance Certificates (other than the Class 622 Third Avenue
Participation 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 P Certificates; second,
to the Class O Certificates; third, to the Class N Certificates; fourth, to the
Class M Certificates; fifth, to the Class L Certificates; sixth, to the Class K
Certificates, seventh, to the Class J Certificates, eighth, to the Class H
Certificates, ninth, to the Class G Certificates, tenth, to the Class F
Certificates, eleventh, to the Class E Certificates, twelfth, to the Class D
Certificates, thirteenth, to the Class C Certificates, and fourteenth, to the
Class B Certificates, in each case, until the remaining Class Principal Balance
of each such Class of Certificates has been reduced to zero. Following the
reduction of the Class Principal Balances of all such Classes to zero, any
remaining Collateral Support Deficit shall be allocated among the Class A-1,
Class A-2, Class A-3, Class A-4, and Class A-5 Certificates, pro rata (based
upon the Class Principal Balance of each such Class), until the remaining Class
Principal 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 (in the case of the Class LA-1-1, Class LA-1-2 and Class LA-1-3
Uncertificated Interests, to each such Uncertificated Lower-Tier Interest, in
that order; in the case of the Class LA-2-1, Class LA-2-2 and Class LA-2-3
Uncertificated Interests, to each such Uncertificated Lower-Tier Interest, in
that order; in the case of the Class LA-3-1 and Class LA-3-2 Uncertificated
Interests, to each such Uncertificated Lower-Tier Interest, in that order; in
the case of the Class LA-4-1 and Class LA-4-2 Uncertificated Interests, to each
such Uncertificated Lower-Tier Interest, in that order; in the case of the Class
LA-5-1 and Class LA-5-2 Uncertificated Interests, to each such Uncertificated
Lower-Tier Interest, in that order; in the case of the Class LD-1 and Class LD-2
Uncertificated Interests, to each such Uncertificated Lower-Tier Interest, in
that order; in the case of the Class LE-1 and Class LE-2 Uncertificated
Interests, to each such Uncertificated Lower-Tier Interest, in that order; and
in the case of the Class LF-1 and Class LF-2 Uncertificated Interests, to each
such Uncertificated Lower-Tier Interest, in that order).

            (d) On each Distribution Date, immediately following the
distribution to be made on such date pursuant to Section 4.01, the Trustee shall
calculate the amount, if any, by which (i) the Stated Principal Balance of the
622 Third Avenue Loan (or any related REO Mortgage Loan) expected to be
outstanding immediately following such Distribution Date is less than (ii) the
sum of the Stated Principal Balance of the 622 Third Avenue Pooled Portion and
the Certificate Balance of the Class 622 Participation Certificates,
respectively, after giving effect to distributions of principal on such
Distribution Date (any such deficit, the "622 Third Avenue Collateral Support
Deficit"). Following each Servicer Remittance Date, the 622 Third Avenue
Collateral Support Deficit will be allocated as follows: first, to the Class
622-F Participation Certificates, until the remaining Certificate Balance of
such Class has been reduced to zero; second, to the Class 622-E Participation
Certificates, until the remaining Certificate Balance of such Class has been
reduced to zero; third, to the Class 622-D Participation Certificates, until the
remaining Certificate Balance of such Class has been reduced to zero, fourth, to
the Class 622-C Participation Certificates, until the remaining Certificate
Balance of such Class has been reduced to zero; fifth, to the Class 622-B
Participation Certificates, until the remaining Certificate Balance of such
Class has been reduced to zero; sixth, to the Class 622-A Participation
Certificates, until the remaining Certificate Balance of such Class has been
reduced to zero; and then, to the 622 Third Avenue Pooled Portion, until the
Stated Principal Balance thereof has been reduced to zero. Any allocation of 622
Third Avenue Collateral Support Deficits to any class of the Class 622
Participation Certificates shall be made by reducing the Certificate Balance
thereof by the amount so allocated. Any allocation of 622 Third Avenue
Collateral Support Deficit to the 622 Third Avenue Pooled Portion shall be made
by reducing the Stated Principal Balance thereof by the amount so allocated. Any
622 Third Avenue Collateral Support Deficit allocated to Class 622 Participation
Certificates shall be allocated among the respective Certificates of such Class
in proportion to the Percentage Interests evidenced thereby. Any 622 Third
Avenue Collateral Support Deficit allocated to the Class 622 Participation
Certificates with respect to a Distribution Date shall reduce the Lower-Tier
Principal Amount of the Class L622 Uncertificated Interests, in reverse
sequential order, as a write off, as applicable. The allocation of 622 Third
Avenue Collateral Support Deficits shall constitute an allocation of losses and
other shortfalls experienced by the Trust Fund with respect to the 622 Third
Avenue Loan. Any 622 Third Avenue Collateral Support Deficit allocated to the
622 Third Avenue Pooled Portion shall be treated as a loss on the related loan
consisting of the 622 Third Avenue Pooled Portion and will result in a
Collateral Support Deficit. Reimbursement of previously allocated 622 Third
Avenue Collateral Support Deficits will not constitute distributions of
principal for any purpose and will not result in an additional reduction in the
Certificate Balance of the Class 622 Participation Certificates, the Lower-Tier
Principal Amount of the related Uncertificated Lower-Tier Interests or the
Stated Principal Balance of the 622 Third Avenue Pooled Portion or the 622 Third
Avenue Non-Pooled Portion.

            (e) Any Appraisal Reduction Amount calculated with respect to the
622 Third Avenue Loan will be allocated first to the Class 622-C Participation
Certificates, second to the Class 622-B Participation Certificates and then to
the Class 622-A Participation Certificates, in that order.

            Section 4.05 Calculations

            Provided that the Trustee receives the necessary information from
each Master Servicer and/or each Special Servicer, the Trustee shall be
responsible for performing all calculations necessary in connection with the
actual and deemed distributions to be made pursuant to Section 4.01, the
preparation of the Statement to Certificateholders pursuant to Section 4.02(a)
and the actual and deemed allocations of Collateral Support Deficit to be made
pursuant to Section 4.04. The Trustee shall calculate the Available Distribution
Amount for each Distribution Date and shall allocate such amounts among
Certificateholders in accordance with this Agreement. Absent actual knowledge of
an error therein, the Trustee shall have no obligation to recompute, recalculate
or otherwise verify any information provided to it by a Master Servicer. The
calculations by the Trustee contemplated by this Section 4.05 shall, in the
absence of manifest error, be presumptively deemed to be correct for all
purposes hereunder.


                                    ARTICLE V

                                THE CERTIFICATES

            Section 5.01 The Certificates

            (a) The Certificates shall consist of thirty-one (31) Classes with
the following respective alphabetic or alphanumeric Class designations: "A-X",
"A-Y", "A-SP", "A-1", "A-2", "A-3", "A-4", "A-5", "B", "C", "D", "E", "F", "G",
"H", "J", "K", "L", "M", "N", "O", "P", "R", "LR", "V", "622-A", "622-B",
"622-C", "622-D", "622-E" and "622-F", respectively. Any reference in any other
section or subsection of this Agreement to any Certificate or Certificates
preceded by a Class designation shall be to a Certificate or Certificates of the
Class so designated in this Section 5.01(a).

            (b) The Certificates will be substantially in the respective forms
attached hereto as Exhibits A-1 through A-6; provided, however, that any of the
Certificates may be issued with appropriate insertions, omissions, substitutions
and variations, and may have imprinted or otherwise reproduced thereon such
legend or legends, not inconsistent with the provisions of this Agreement, as
may be required to comply with any law or with rules or regulations pursuant
thereto, or with the rules of any securities market in which the Certificates
are admitted to trading, or to conform to general usage. The Certificates will
be issuable in registered form only; provided, however, that in accordance with
Section 5.03 beneficial ownership interests in the Class A-X, Class A-SP, Class
A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class B, Class C, Class D,
Class E, Class F, Class G, Class H, Class J, Class K and Class L and
Certificates and the Class 622 Participation Certificates initially shall (and,
at the option of the Depositor, following the Closing Date, all or a portion of
any other Class of Certificates may) be held and transferred through the
book-entry facilities of the Depository. The Class A-X, Class A-SP, Class A-1,
Class A-2, Class A-3, Class A-4, Class A-5, Class B, Class C, Class D, Class E,
Class F, Class G, Class H, Class J, Class K, Class L, Class M, Class N, Class O
and Class P Certificates and the Class 622-A, Class 622-B, Class 622-C, Class
622-D, Class 622-E and Class 622-F Participation Certificates will be issuable
only in denominations corresponding to initial Certificate Principal Balances
(or, in the case of the Interest Only Certificates, initial Certificate Notional
Amounts) as of the Closing Date of not less than $10,000 and any whole dollar
denomination in excess thereof. The Class R Certificates, the Class LR, the
Class A-Y Certificates and the Class V Certificates will be issuable only in
denominations representing Percentage Interests in the related Class of not less
than 10.0%.

            (c) The Certificates shall be executed by manual or facsimile
signature on behalf of the Trustee in its capacity as trustee hereunder by an
authorized signatory. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the authorized signatory of the Trustee 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
Certificate Registrar by manual signature, and such certificate of
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder. All Certificates shall be dated the date of their authentication.

            Section 5.02 Registration of Transfer and Exchange of Certificates

            (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar
(located as of the Closing Date at Wells Fargo Center, Sixth and Marquette, MAC#
N9303-121, Minneapolis, Minnesota, 55479-0113 may prescribe, the Certificate
Registrar shall provide for the registration of Certificates and of transfers
and exchanges of Certificates as herein provided. The Trustee is hereby
initially appointed (and hereby agrees to act in accordance with the terms
hereof) as Certificate Registrar for the purpose of registering Certificates and
transfers and exchanges of Certificates as herein provided. The Trustee may
appoint, by a written instrument delivered to the other parties hereto, any
other bank or trust company to act as Certificate Registrar under such
conditions as the Trustee may prescribe, provided that the Trustee shall not be
relieved of any of its duties or responsibilities hereunder as Certificate
Registrar by reason of such appointment. If the Trustee resigns or is removed in
accordance with the terms hereof, the successor trustee shall immediately
succeed to its predecessor's duties as Certificate Registrar. The Depositor, the
Master Servicers and the Special Servicers shall each 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.

            If three or more Certificateholders make a written request to the
Trustee, and such request states that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates and is accompanied by a copy of the
communication that such requesting Certificateholders propose to transmit, then
the Trustee shall, within 30 days after the receipt of such request, afford (or
cause any other Certificate Registrar to afford) the requesting
Certificateholders access during normal business hours to, or deliver to the
requesting Certificateholders a copy of, the most recent list of
Certificateholders held by the Certificate Registrar (which list shall be
current as of a date no earlier than 30 days prior to the Trustee's receipt of
such request). Every Certificateholder, by receiving such access, acknowledges
that neither the Certificate Registrar nor the Trustee will be held accountable
in any way by reason of the disclosure of any information as to the names and
addresses of any Certificateholder regardless of the source from which such
information was derived.

            (b) No transfer, sale, pledge or other disposition of any
Non-Registered Certificate or interest therein shall be made unless that
transfer, sale, pledge or other disposition is exempt from the registration
and/or qualification requirements of the Securities Act and any applicable state
securities laws, or is otherwise made in accordance with the Securities Act and
such state securities laws.

            If a transfer of any Non-Registered Certificate (other than a
Book-Entry Non-Registered Certificate) is to be made without registration under
the Securities Act (other than in connection with the initial issuance of the
Certificates or a transfer of such Non-Registered Certificate by the Depositor
or an Affiliate of the Depositor or, in the case of a Global Certificate, any
transfer of such Certificate to a successor Depository or, in the case of a
Definitive Certificate issued with respect to a Global Certificate, any transfer
of such Certificate to the applicable Certificate Owner in accordance with
Section 5.03(c)), then the Certificate Registrar shall refuse to register such
transfer unless it receives (and, upon receipt, may conclusively rely upon)
either: (i) a certificate from the Certificateholder desiring to effect such
transfer substantially in the form attached hereto as Exhibit F-1A; or (ii) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached hereto as Exhibit F-1B and a certificate from
such Certificateholder's prospective Transferee substantially in the form
attached hereto either as Exhibit F-2A or as Exhibit F-2B; or (iii) an Opinion
of Counsel satisfactory to the Trustee to the effect that such transfer may be
made without registration under the Securities Act (which Opinion of Counsel
shall not be an expense of the Trust or of the Depositor, the Master Servicers,
the Special Servicers, the Trustee, any Fiscal Agent or the Certificate
Registrar in their respective capacities as such), together with the written
certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based.

            Each Global Certificate shall be deposited with the Trustee as
custodian for the Depository and registered in the name of Cede & Co. as nominee
of the Depository.

            If a transfer of an interest in any Rule 144A Global Certificate is
to be made without registration under the Securities Act (other than in
connection with the initial issuance of the Certificates or a transfer of an
interest in such Rule 144A Global Certificate by the Depositor or an Affiliate
of the Depositor), then (except as provided in the next succeeding paragraph or
in the penultimate paragraph of this Section 5.02(b)) the Certificate Owner
desiring to effect such transfer shall require from its prospective Transferee:
(i) a certificate substantially in the form attached as Exhibit F-2C hereto; or
(ii) an Opinion of Counsel to the effect that the prospective Transferee is a
Qualified Institutional Buyer and such transfer may be made without registration
under the Securities Act. Except as provided in the next succeeding paragraph or
in the penultimate paragraph of this Section 5.02(b), any interest in a Rule
144A Global Certificate shall not be transferred to any Person other than a
Qualified Institutional Buyer that takes delivery in the form of an interest in
such Rule 144A Global Certificate. If any Transferee of an interest in a Rule
144A Global Certificate does not, in connection with the subject transfer,
deliver to the Transferor the Opinion of Counsel or the certification described
in the second preceding sentence, then such Transferee shall be deemed to have
represented and warranted that all the certifications set forth in Exhibit F-2C
hereto are, with respect to the subject transfer, true and correct.

            Notwithstanding the preceding paragraph, any interest in the Rule
144A Global Certificate with respect to the Class A-X, Class A-SP, Class F,
Class G, Class H, Class J, Class K, Class L, Class M, Class N, Class O or Class
P Certificates and the Class 622 Participation Certificates may be transferred
(without delivery of any certificate or Opinion of Counsel described in clauses
(i) and (ii) of the first sentence of the preceding paragraph) to any Person who
takes delivery in the form of a beneficial interest in the Regulation S Global
Certificate for the same Class as such Rule 144A Global Certificate upon
delivery to the Certificate Registrar and the Trustee of (i) a certificate from
the Certificate Owner desiring to effect such transfer substantially in the form
attached hereto as Exhibit F-1D and a certificate from such Certificate Owner's
prospective Transferee substantially in the form attached hereto as Exhibit F-2D
and (ii) such written orders and instructions as are required under the
applicable procedures of the Depository, Clearstream and/or Euroclear to direct
the Trustee to debit the account of a Depository Participant by a denomination
of interests in such Rule 144A Global Certificate, and credit the account of a
Depository Participant by a denomination of interests in such Regulation S
Global Certificate, that is equal to the denomination of beneficial interests in
the Class A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L,
Class M, Class N, Class O or Class P Certificates or the Class 622 Participation
Certificates to be transferred. Upon delivery to the Trustee of such
certifications and such orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of the Depository, shall reduce the
denomination of the Rule 144A Global Certificate with respect to the Class A-X,
Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L, Class M, Class
N, Class O or Class P Certificates or the Class 622 Participation Certificates,
and increase the denomination of the Regulation S Global Certificate for such
Class, by the denomination of the beneficial interest in such Class specified in
such orders and instructions.

            Except as provided in the next succeeding paragraph or in the
penultimate paragraph of this Section 5.02(b), beneficial interests in any
Regulation S Global Certificate shall not be transferred to any Person other
than a non-United States Securities Person that takes delivery in the form of a
beneficial interest in such Regulation S Global Certificate, and the Certificate
Owner desiring to effect such transfer shall be required to obtain from such
prospective Transferee a certification substantially in the form attached hereto
as Exhibit F-2D. On or prior to the Release Date, beneficial interests in any
Regulation S Global Certificate may be held only through Euroclear or
Clearstream.

            Notwithstanding the preceding paragraph, following the Release Date,
any interest in the Regulation S Global Certificate with respect to the Class
A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L, Class M,
Class N, Class O or Class P Certificates or the Class 622 Participation
Certificates may be transferred (without delivery of any certificate described
in the first sentence of the preceding paragraph) to any Person who takes
delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for the same Class as such Regulation S Global Certificate upon
delivery to the Certificate Registrar and the Trustee of (i) a certificate from
the Certificate Owner desiring to effect such transfer substantially in the form
attached hereto as Exhibit F-1C and a certificate from such Certificate Owner's
prospective Transferee substantially in the form attached hereto as Exhibit F-2C
and (ii) such written orders and instructions as are required under the
applicable procedures of the Depository, Clearstream and/or Euroclear to direct
the Trustee to debit the account of a Depository Participant by a denomination
of interests in such Regulation S Global Certificate, and credit the account of
a Depository Participant by a denomination of interests in such Rule 144A Global
Certificate, that is equal to the denomination of beneficial interests in the
Class A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L,
Class M, Class N, Class O or Class P Certificates or Class 622 Participation
Certificates to be transferred. Upon delivery to the Trustee of such
certifications and such orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of the Depository, shall reduce the
denomination of the Regulation S Global Certificate with respect to the Class
A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L, Class M,
Class N, Class O or Class P Certificates or Class 622 Participation
Certificates, and increase the denomination of the Rule 144A Global Certificate
for such Class, by the denomination of the beneficial interest in such Class
specified in such orders and instructions.

            Notwithstanding the foregoing, any interest in a Global Certificate
with respect to the Class A-X, Class A-SP, Class F, Class G, Class H, Class J,
Class K, Class L, Class M, Class N, Class O or Class P Certificates or Class 622
Participation Certificates may be transferred by any Certificate Owner holding
such interest to any Person who takes delivery in the form of a Definitive
Certificate of the same Class as such Global Certificate upon delivery to the
Certificate Registrar and the Trustee of (i) such certifications and/or opinions
as are contemplated by the second paragraph of this Section 5.02(b) and (ii)
such written orders and instructions as are required under the applicable
procedures of the Depository, Clearstream and/or Euroclear to direct the Trustee
to debit the account of a Depository Participant by a denomination of interests
in such Global Certificate. Upon delivery to the Certificate Registrar of the
certifications and/or opinions contemplated by the second paragraph of this
Section 5.02(b), the Trustee, subject to and in accordance with the applicable
procedures of the Depository, shall reduce the denomination of the subject
Global Certificate, and cause a Definitive Certificate of the same Class as such
Global Certificate, and in a denomination equal to the reduction in the
denomination of such Global Certificate, to be executed, authenticated and
delivered in accordance with this Agreement to the applicable Transferee.

            None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify any Class of Non-Registered Certificates under
the Securities Act or any other securities law or to take any action not
otherwise required under this Agreement to permit the transfer of any
Non-Registered Certificate or interest therein without registration or
qualification. Any Certificateholder or Certificate Owner desiring to effect a
transfer, sale, pledge or other disposition of any Non-Registered Certificate or
interest therein shall, and does hereby agree to, indemnify the Depositor, CSFB
LLC, the Trustee, any Fiscal Agent, the Master Servicers, the Special Servicers
and the Certificate Registrar against any liability that may result if such
transfer, sale, pledge or other disposition is not exempt from the registration
and/or qualification requirements of the Securities Act and any applicable state
securities laws or is not made in accordance with such federal and state laws.

            (c) No transfer of any Certificate or interest therein shall be made
to a Plan or to any Person who is directly or indirectly purchasing such
Certificate on behalf of, as named fiduciary of, as trustee of, or with assets
of a Plan, if the purchase and holding of such Certificate or interest therein
by the prospective Transferee would result in a violation of Section 406 or 407
of ERISA or Section 4975 of the Code or any materially similar provisions of
applicable federal, state or local law ("Similar Law") or would result in the
imposition of an excise tax under Section 4975 of the Code or Similar Law.

            Except in connection with the initial issuance of the Certificates
or any transfer of a Non-Registered Certificate by the Depositor or an Affiliate
of the Depositor or, in the case of a Global Certificate, any transfer of such
Certificate to a successor Depository or, in the case of a Definitive
Certificate issued with respect to a Global Certificate, any transfer of such
Certificate to the applicable Certificate Owner in accordance with Section
5.03(c), the Certificate Registrar shall refuse to register the transfer of a
Non-Registered Certificate unless it has received from the prospective
Transferee any of the following: (i) a certification to the effect that such
prospective Transferee is not a Plan and is not directly or indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with assets of a Plan; or (ii) except in the case of a
Class R, Class LR or Class V Certificate, a certification to the effect that the
purchase and continued holding of such Certificate by such prospective
Transferee is exempt from the prohibited transaction provisions of Section 406
and 407 of ERISA and Section 4975 of the Code by reason of Sections I and III of
Prohibited Transaction Class Exemption 95-60 (or similar exemption under Similar
Law); or (iii) in the case of a Non-Registered Certificate (other than a Class
R, Class LR or Class V Certificate) that is rated investment grade by at least
one of the Rating Agencies and is being acquired by or on behalf of a Plan in
reliance on the Underwriter Exemption, a certification to the effect that such
Plan (X) is an accredited investor as defined in Rule 501(a)(1) of Regulation D
of the Securities Act, (Y) is not sponsored (within the meaning of Section
3(16)(B) of ERISA) by the Trustee, any Exemption-Favored Party, the Depositor,
any Mortgage Loan Seller, either Master Servicer, either Special Servicer, any
Sub-Servicer, any Person responsible for servicing the Great Lakes Crossing
Mortgage Loan or any Great Lakes Crossing REO Property or any Borrower with
respect to Mortgage Loans constituting 5% of the aggregate unamortized principal
of all the Mortgage Loans determined as of the Closing Date, or by any Affiliate
of such Person, and (Z) agrees that it will obtain from each of its Transferees
a written representation that such Transferee, if a Plan, satisfies the
requirements of the immediately preceding clauses (iii)(X) and (iii)(Y),
together with a written agreement that such Transferee will obtain from each of
its Transferees that are Plans a similar written representation regarding
satisfaction of the requirements of the immediately preceding clauses (iii)(X)
and (iii)(Y); or (iv) except in the case of a Class R, Class LR or Class V
Certificate, a certification of facts and an Opinion of Counsel (which Opinion
of Counsel shall not be an expense of the Trustee, the Certificate Registrar or
the Trust) which otherwise establish to the reasonable satisfaction of the
Trustee that such transfer will not result in a violation of Section 406 or 407
of ERISA or Section 4975 of the Code or similar violation of Similar Law or
result in the imposition of an excise tax under Section 4975 of the Code or
Similar Law. It is hereby acknowledged that the form of certification attached
hereto as Exhibit G 1 is acceptable for purposes of the preceding sentence.

            Except in connection with the initial issuance of the Certificates
or any transfer of an interest in a Book-Entry Non-Registered Certificate by the
Depositor or an Affiliate of the Depositor, the Certificate Owner desiring to
effect a transfer of an interest in a Book-Entry Non-Registered Certificate
shall obtain from its prospective Transferee one of the following: (i) a
certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing such interest in such Certificate on
behalf of, as named fiduciary of, as trustee of, or with assets of a Plan; or
(ii) except in the case of a Class R, Class LR or Class V Certificate, a
certification to the effect that the purchase and continued holding of an
interest in such Certificate by such prospective Transferee is exempt from the
prohibited transaction provisions of Sections 406 and 407 of ERISA and Section
4975 of the Code by reason of Sections I and III of Prohibited Transaction Class
Exemption 95-60 (or similar exemption under Similar Law); or (iii) if such
Certificate is not a Class R, Class LR or Class V Certificate, if such
Certificate is rated investment grade by at least one of the Rating Agencies and
if the interest in such Certificate is being acquired by or on behalf of a Plan
in reliance on the Underwriter Exemption, a certification to the effect that
such Plan (X) is an accredited investor as defined in Rule 501(a)(1) of
Regulation D of the Securities Act, (Y) is not sponsored (within the meaning of
Section 3(16)(B) of ERISA) by the Trustee, the Depositor, any Mortgage Loan
Seller, either Master Servicer, either Special Servicer, any Sub-Servicer, any
Person responsible for servicing the Great Lakes Crossing Mortgage Loan or any
Great Lakes Crossing REO Property or any Borrower with respect to Mortgage Loans
constituting 5% of the aggregate unamortized principal of all the Mortgage Loans
determined as of the Closing Date, or by any Affiliate of such Person, and (Z)
agrees that it will obtain from each of its Transferees a written representation
that such Transferee, if a Plan, satisfies the requirements of the immediately
preceding clauses (iii)(X) and (iii)(Y), together with a written agreement that
such Transferee will obtain from each of its Transferees that are Plans a
similar written representation regarding satisfaction of the requirements of the
immediately preceding clauses (iii)(X) and (iii)(Y); or (iv) except in the case
of a Class R, Class LR or Class V Certificate, a certification of facts and an
Opinion of Counsel to the effect that such transfer will not result in a
violation of Section 406 or 407 of ERISA or Section 4975 of the Code or similar
violations of Similar Law or result in the imposition of an excise tax under
Section 4975 of the Code or Similar Law. It is hereby acknowledged that the form
of certification attached hereto as Exhibit G-2 is acceptable for purposes of
the preceding sentence.

            Each Transferee of any Registered Certificate or interest therein or
of an interest in any Book-Entry Non-Registered Certificate shall be deemed to
have represented and warranted that either: (i) such Transferee is not a Plan
and is not directly or indirectly purchasing such Certificate or interest
therein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan; or (ii) the purchase and continued holding of such Certificate or interest
therein by such Transferee is exempt from the prohibited transaction provisions
of Section 406 and 407 of ERISA and Section 4975 of the Code and similar
provisions of Similar Law.

            (d) (i) Each Person who has or acquires any Ownership Interest in a
Class R or Class LR 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 Trustee under clause (d)(ii)
below to deliver payments to a Person other than such Person and, further, to
negotiate the terms of any mandatory disposition and to execute all instruments
of Transfer and do all other things necessary in connection with any such
disposition. The rights of each Person acquiring any Ownership Interest in a
Class R or Class LR Certificate are expressly subject to the following
provisions:

                  (A) Each Person holding or acquiring any Ownership Interest in
            a Class R or Class LR Certificate shall be a Permitted Transferee
            and shall promptly notify the Trustee of any change or impending
            change in its status as a Permitted Transferee.

                  (B) In connection with any proposed Transfer of any Ownership
            Interest in a Class R or Class LR Certificate, the Certificate
            Registrar shall require delivery to it, and shall not register the
            Transfer of any Class R or Class LR Certificate until its receipt,
            of an affidavit substantially in the form attached hereto as Exhibit
            H-1 (a "Residual Transfer Affidavit"), from the proposed Transferee,
            representing and warranting, among other things, that such
            Transferee is a Permitted Transferee, that it is not acquiring its
            Ownership Interest in the Class R or Class LR Certificate that is
            the subject of the proposed Transfer as a nominee, trustee or agent
            for any Person that is not a Permitted Transferee, that for so long
            as it retains its Ownership Interest in a Class R or Class LR
            Certificate it will endeavor to remain a Permitted Transferee, and
            that it has reviewed the provisions of this Section 5.02(d) and
            agrees to be bound by them.

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

                  (D) Each Person holding or acquiring any Ownership Interest in
            a Class R or Class LR Certificate shall agree (1) to require a
            Residual Transfer Affidavit from any prospective Transferee to whom
            such Person attempts to transfer its Ownership Interest in such
            Class R or Class LR Certificate and (2) not to transfer its
            Ownership Interest in such Class R or Class LR Certificate unless it
            provides to the Certificate Registrar and the Trustee a certificate
            substantially in the form attached hereto as Exhibit H-2 stating
            that, among other things, it has no actual knowledge that such
            prospective Transferee is not a Permitted Transferee.

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

            (ii) If any purported Transferee shall become a Holder of a Class R
      or Class LR Certificate in violation of the provisions of this Section
      5.02(d), then the last preceding Holder of such Class R or Class LR
      Certificate that was in compliance with the provisions of this Section
      5.02(d) shall be restored, to the extent permitted by law, to all rights
      as Holder thereof retroactive to the date of registration of such Transfer
      of such Class R or Class LR Certificate. None of the Depositor, the
      Trustee or the Certificate Registrar shall be under any liability to any
      Person for any registration of Transfer of a Class R or Class LR
      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.

            If any purported Transferee shall become a Holder of a Class R or
Class LR Certificate in violation of the restrictions in this Section 5.02(d),
then, to the extent that retroactive restoration of the rights of the preceding
Holder of such Class R or Class LR Certificate as described in the preceding
paragraph of this clause (d)(ii) shall be invalid, illegal or unenforceable, the
Trustee shall have the right, but not the obligation, to cause the transfer of
such Class R or Class LR Certificate to a Permitted Transferee selected by the
Trustee on such terms as the Trustee may choose, and the Trustee shall not be
liable to any Person having an Ownership Interest in such Class R or Class LR
Certificate or any other Person as a result of its exercise of such discretion.
Such purported Transferee shall promptly endorse and deliver such Class R or
Class LR Certificate in accordance with the instructions of the Trustee. Such
Permitted Transferee may be the Trustee itself or any Affiliate of the Trustee.

            (iii) The Trustee shall make available to the IRS and to those
      Persons specified by the REMIC Provisions all information furnished to it
      by the other parties hereto necessary to compute any tax imposed as a
      result of the Transfer of an Ownership Interest in a Class R or Class LR
      Certificate to any Person who is a Disqualified Organization, 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" for the
      Upper-Tier REMIC (in the case of the Class R Certificates), the Lower-Tier
      REMIC and the 622 Third Avenue Loan REMIC (in the case of the Class LR
      Certificates), and each of the other parties hereto shall furnish to the
      Trustee all information in its possession necessary for the Trustee to
      discharge such obligation. The Person holding such Ownership Interest
      shall be responsible for the reasonable compensation of the Trustee for
      providing such information.

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

                  (A) written confirmation from each Rating Agency to the effect
            that the modification of, addition to or elimination of such
            provisions will not result in an Adverse Rating Event with respect
            to any Class of Rated Certificates; and

                  (B) an Opinion of Counsel, in form and substance satisfactory
            to the Trustee, obtained at the expense of the party seeking such
            modification of, addition to or elimination of such provisions (but
            in no event at the expense of the Trustee or the Trust), to the
            effect that doing so will not (1) cause any Trust REMIC to cease to
            qualify as a REMIC or be subject to an entity-level tax caused by
            the Transfer of any Class R or Class LR Certificate to a Person
            which is not a Permitted Transferee or (2) cause a Person other than
            the prospective Transferee to be subject to a REMIC-related tax
            caused by the Transfer of a Class R or Class LR Certificate to a
            Person that is not a Permitted Transferee.

            (e) If a Person is acquiring any Non-Registered Certificate as a
fiduciary or agent for one or more accounts, such Person shall be required to
deliver to the Certificate Registrar a certification to the effect that, and
such other evidence as may be reasonably required by the Trustee to confirm
that, it has (i) sole investment discretion with respect to each such account
and (ii) full power to make the applicable foregoing acknowledgments,
representations, warranties, certifications and/or agreements with respect to
each such account as set forth in Subsections (b), (c) and/or (d), as
appropriate, of this Section 5.02.

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

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

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

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

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

            (k) The Certificate Registrar or the Trustee shall provide to each
of the other parties hereto, upon reasonable written request and at the expense
of the requesting party, an updated copy of the Certificate Register.

            Section 5.03 Book-Entry Certificates

            (a) The Class A-X, Class A-SP, Class A-1, Class A-2, Class A-3,
Class A-4, Class A-5, Class B, Class C, Class D, Class E, Class F, Class G,
Class H, Class J, Class K, Class L and Class M Certificates and the Class 622
Participation Certificates shall, in the case of each Class thereof, initially
be issued (and, at the option of the Depositor, subsequent to the Closing Date,
all or any portion of any other Class of Certificates may be issued) as one or
more Certificates registered in the name of the Depository or its nominee and,
except as provided in Section 5.02(b) or Section 5.03(c), 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, subject to Section 5.02, transfer their
respective Ownership Interests in and to such Certificates through the
book-entry facilities of the Depository; and, except as provided in Section
5.02(b) or Section 5.03(c) below, shall not be entitled to fully registered,
physical Certificates ("Definitive Certificates") in respect of such Ownership
Interests. All transfers by Certificate Owners of their respective Ownership
Interests in the Book-Entry Certificates shall be made in accordance with the
procedures established by the Depository Participant or indirect participating
brokerage firm representing each such Certificate Owner. Each Depository
Participant shall only transfer the Ownership Interests in the Book-Entry
Certificates of Certificate Owners it represents or of indirect participating
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures.

            (b) Except as expressly provided to the contrary herein, the
Depositor, the Master Servicers, the Special Servicers, the Trustee, any Fiscal
Agent 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. Except as expressly provided to the contrary herein, 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 indirect participating brokerage firms
representing such Certificate Owners. Multiple requests and directions from, and
votes of, the Depository as Holder of the Book-Entry Certificates with respect
to any particular matter shall not be deemed inconsistent if they are made with
respect to different Certificate Owners. The Trustee may establish a reasonable
record date in connection with solicitations of consents from or voting by
Certificateholders and shall give notice to the Depository of such record date.

            (c) If (i)(A) the Depositor advises the Trustee and the Certificate
Registrar in writing that the Depository is no longer willing or able to
discharge properly its responsibilities with respect to any Class of Book-Entry
Certificates, and (B) the Depositor is unable to locate a qualified successor,
(ii) the Depositor at its option advises the Trustee and the Certificate
Registrar in writing that it elects to terminate the book-entry system through
the Depository with respect to all or any portion of any Class of Book-Entry
Certificates, or (iii) the Trustee determines that Definitive Certificates are
required because the Trustee has instituted or has been directed to institute
judicial proceedings in a court to enforce the right of the Certificateholders
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 those Certificates evidenced by Book-Entry
Certificates, the Certificate Registrar shall notify all affected Certificate
Owners, through the Depository, of the occurrence of any such event and of the
availability of Definitive Certificates to such Certificate Owners requesting
the same. Upon surrender to the Certificate Registrar of any Class of Book-Entry
Certificates (or any portion of any Class thereof) by the Depository,
accompanied by registration instructions from the Depository for registration of
transfer, the Trustee shall execute, and the Certificate Registrar shall
authenticate and deliver, the Definitive Certificates in respect of such Class
(or portion thereof) to the Certificate Owners identified in such instructions.
None of the Depositor, the Master Servicers, the Special Servicers, the Trustee
or the Certificate Registrar shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Certificates for purposes of
evidencing ownership of any Book-Entry 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.

            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 reasonably 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 Trustee shall
execute and the Certificate Registrar shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of the same Class and like Percentage Interest.
Upon the issuance of any new Certificate under this Section, the Trustee and the
Certificate Registrar may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other reasonable expenses (including the reasonable 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 presentment for registration of transfer, the
Depositor, the Master Servicers, the Special Servicers, the Trustee, any Fiscal
Agent, the Certificate Registrar and any agent of any of them may treat the
Person in whose name any 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, and none of the Depositor, the Master
Servicers, the Special Servicers, the Trustee, any Fiscal Agent, the Certificate
Registrar or any agent of any of them shall be affected by notice to the
contrary.

            Section 5.06 Certification by Certificateholders and Certificate
Owners

            (a) Each Certificate Owner is hereby deemed by virtue of its
acquisition of an Ownership Interest in the Book-Entry Certificates to agree to
comply with the transfer requirements of Section 5.02.

            (b) To the extent that under the terms of this Agreement, it is
necessary to determine whether any Person is a Certificateholder or a
Certificate Owner, the Trustee shall make such determination based on a
certificate of such Person which shall be substantially in the form of paragraph
1 of Exhibit K-1 hereto (or such other form as shall be reasonably acceptable to
the Trustee) and shall specify the Class and Certificate Principal Balance or
Certificate Notional Amount, as the case may be, of the Book-Entry Certificate
beneficially owned; provided, however, that the Trustee shall not knowingly
recognize such Person as a Certificate Owner if such Person, to the knowledge of
a Responsible Officer of the Trustee, acquired its Ownership Interest in a
Book-Entry Certificate in violation of Section 5.02, or if such Person's
certification that it is a Certificate Owner is in direct conflict with
information obtained by the Trustee from the Depository, Depository Participants
and/or indirect participating brokerage firms for which Depository Participants
act as agents, with respect to the identity of a Certificate Owner. The Trustee
shall exercise its reasonable discretion in making any determination under this
Section 5.06(b) and shall afford any Person providing information with respect
to its beneficial ownership of any Book-Entry Certificate an opportunity to
resolve any discrepancies between the information provided and any other
information available to the Trustee.

                     THE DEPOSITOR, THE MASTER SERVICERS AND
                              THE SPECIAL SERVICERS

            Section 6.01 Liability of the Depositor, the Master Servicers and
the Special Servicers

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

            Section 6.02 Merger, Consolidation or Conversion of the Depositor,
the Master Servicers or the Special Servicers

            (a) Subject to Section 6.02(b), the Depositor, the Master Servicers
and the Special Servicers shall each keep in full effect its existence, rights
and franchises as a corporation, bank, trust company, partnership, limited
liability company, association or other legal entity under the laws of the
jurisdiction wherein it was organized, and each shall obtain and preserve its
qualification to do business as a foreign entity in each jurisdiction in which
such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

            (b) Each of the Depositor, the Master Servicers and the Special
Servicers may be merged or consolidated with or into any Person, or transfer all
or substantially all of its assets to any Person, in which case, any Person
resulting from any merger or consolidation to which the Depositor, a Master
Servicer or a Special Servicer shall be a party, or any Person succeeding to the
business of the Depositor, a Master Servicer or a Special Servicer, shall be the
successor of the Depositor, such Master Servicer or such Special Servicer, as
the case may be, hereunder, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding; provided, however, that no successor or surviving
Person shall succeed to the rights of a Master Servicer or a Special Servicer
unless (i) such succession will not result in an Adverse Rating Event with
respect to any Class of Rated Certificates (as confirmed in writing to the
Trustee by each Rating Agency) and (ii) such successor or surviving Person makes
the applicable representations and warranties set forth in Section 2.05 (in the
case of a successor or surviving Person to the General Master Servicer); Section
2.06 (in the case of a successor or surviving Person to the General Special
Servicer); Section 2.07 (in the case of a successor or surviving Person to the
NCBFSB Master Servicer) or Section 2.08 (in the case of a successor or surviving
Person to the Co-op Special Servicer) as applicable.

            Section 6.03 Limitation on Liability of the Depositor, the Master
Servicers and the Special Servicers

            None of the Depositor, the Master Servicers or the Special Servicers
shall be under any liability to the Trust, the Trustee, any B Loan Holder or the
Certificateholders for any action taken or not taken in good faith pursuant to
this Agreement or for errors in judgment; provided, however, that this provision
shall not protect the Depositor, the Master Servicers or the Special Servicers
against any liability to the Trust, the Trustee or the Certificateholders for
the breach of a representation or warranty made by such party herein, or against
any expense or liability specifically required to be borne by such party without
right of reimbursement pursuant to the terms hereof, or against any liability
which would otherwise be imposed by reason of misfeasance, bad faith or
negligence in the performance of, or negligent disregard of, such party's
obligations or duties hereunder. The Depositor, the Master Servicers or the
Special Servicers and any director, member, manager, officer, employee or agent
of any such party may rely in good faith on any document of any kind which,
prima facie, is properly executed and submitted by any Person respecting any
matters arising hereunder. The Depositor, the Master Servicers or the Special
Servicers and any director, member, manager, officer, employee or agent of any
such party, shall be indemnified and held harmless by the Trust out of the
Collection Account (or, if such indemnification relates exclusively to an A/B
Loan Pair, first out of amounts attributable to an A/B Loan Pair on deposit in
the related A/B Loan Pair Custodial Account and then out of the related
Collection Account) or the Distribution Account, against any loss, liability,
cost or expense (including reasonable legal fees and expenses) incurred in
connection with any legal action or claim relating to this Agreement or the
Certificates, other than any loss, liability, cost or expense: (i) specifically
required to be borne thereby pursuant to the terms hereof; (ii) that constitutes
(or, but for the failure of the subject expense to be customary, reasonable or
necessary, would constitute) a Servicing Advance that is otherwise reimbursable
under this Agreement; or (iii) incurred in connection with any legal action or
claim against such party resulting from any breach of a representation or
warranty made herein, any misfeasance, bad faith or negligence in the
performance of, or negligent disregard of, obligations or duties hereunder or
any willful or negligent violation of applicable law. None of the Depositor, the
Master Servicers or the Special Servicers shall be under any obligation to
appear in, prosecute or defend any legal action unless such action is related to
its respective duties under this Agreement and, except in the case of a legal
action the costs of which such party is specifically required hereunder to bear,
in its opinion does not involve it in any ultimate expense or liability for
which it would not be reimbursed hereunder; provided, however, that the
Depositor, either Master Servicer or either Special Servicer may in its
discretion undertake any such action which it may reasonably deem necessary or
desirable with respect to the enforcement and/or protection of the rights and
duties of the parties hereto and the interests of the Certificateholders
hereunder. In such event, the legal fees and expenses and costs of such action,
and any liability resulting therefrom, shall be expenses, costs and liabilities
of the Trust, and the Depositor, the Master Servicers and the Special Servicers
shall be entitled to be reimbursed therefor from the Collection Account, as
provided in Section 3.05(a) (or, to the extent permitted by the related A/B
Intercreditor Agreement, first out of amounts attributable to an A/B Loan Pair
on deposit in the related A/B Loan Pair Custodial Account and then out of the
related Collection Account) or the Distribution Account.

            In addition, neither the Master Servicers nor the Special Servicers
shall have any liability with respect to, and each shall be entitled to rely as
to the truth of the statements made and the correctness of the opinions
expressed therein on, any certificates or opinions furnished to such Master
Servicer or Special Servicer, as the case may be, and conforming to the
requirements of this Agreement. Each Master Servicer and each Special Servicer
may rely in good faith on information provided to it by the other parties hereto
(unless the provider and the recipient of such information are the same Person
or Affiliates) and by the Borrowers, and will have no duty to investigate or
verify the accuracy thereof.

            Section 6.04 Resignation of Master Servicers and Special Servicers

            (a) Each Master Servicer and each Special Servicer may resign from
the obligations and duties hereby imposed on it, upon a determination that its
duties hereunder are no longer permissible under applicable law or are in
material conflict by reason of applicable law with any other activities carried
on by it (the other activities of such Master Servicer or such Special Servicer,
as the case may be, so causing such a conflict being of a type and nature
carried on by such Master Servicer or such Special Servicer, as the case may be,
at the date of this Agreement). Any such determination requiring the resignation
of a Master Servicer or a Special Servicer, as applicable, shall be evidenced by
an Opinion of Counsel to such effect which shall be delivered to the Trustee.
Unless applicable law requires a Master Servicer's or a Special Servicer's (as
the case may be) resignation to be effective immediately, and the Opinion of
Counsel delivered pursuant to the prior sentence so states, no such resignation
shall become effective until the Trustee or other successor shall have assumed
the responsibilities and obligations of the resigning party in accordance with
Section 6.06 or Section 7.02 hereof; provided that, if no successor master
servicer or special servicer, as applicable, shall have been so appointed and
have accepted appointment within 90 days after such Master Servicer or such
Special Servicer, as the case may be, has given notice of such resignation, the
resigning Master Servicer or Special Servicer, as applicable, may petition any
court of competent jurisdiction for the appointment of a successor thereto; and
provided, further, that such Master Servicer or Special Servicer, as the case
may be, shall, at least 10 days prior to resigning and assigning or transferring
any of its rights, benefits or privileges hereunder, inform the Controlling
Class Representative in writing of its intent to resign and disclose to the
Controlling Class Representative the name of such assignee or transferee and the
date of the proposed resignation and transfer of servicing.

            (b) In addition, each Master Servicer and each Special Servicer
shall have the right to resign at any other time, provided that (i) a willing
successor thereto (including any such successor proposed by the resigning party)
reasonably acceptable to the Depositor and the Trustee has been found, (ii) each
of the Rating Agencies confirms to the Trustee in writing that the successor's
appointment will not result in an Adverse Rating Event with respect to any Class
of Rated Certificates, (iii) the resigning party pays all costs and expenses in
connection with such transfer, and (iv) the successor accepts appointment prior
to the effectiveness of such resignation.

            (c) Neither of the Master Servicers nor the Special Servicers shall
be permitted to resign except as contemplated in subsections (a) and (b) of this
Section 6.04. Consistent with the foregoing, neither of the Master Servicers nor
the Special Servicers shall (except in connection with any resignation thereby
permitted above in this Section 6.04 or as otherwise expressly provided herein,
including the provisions of Section 3.11(a), Section 3.22 and/or Section 6.02)
assign or transfer any of its rights, benefits or privileges hereunder to any
other Person or delegate to, subcontract with, or authorize or appoint any other
Person to perform any of the duties, covenants or obligations to be performed by
it hereunder. If, pursuant to any provision hereof, the duties of a Master
Servicer or a Special Servicer are transferred to a successor thereto, the
entire amount of compensation payable to such Master Servicer or such Special
Servicer, as the case may be, that accrues pursuant hereto from and after the
date of such transfer shall be payable to such successor, except to the extent
provided in Section 3.11(c).

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

            Each Master Servicer and each Special Servicer shall afford the
Depositor, the Trustee, the Controlling Class Representative, the 622 Third
Avenue B Loan Holder, each Washington Center Junior Holder and each Rating
Agency, upon reasonable notice, during normal business hours access to all
records maintained by it in respect of its rights and obligations hereunder and
access to such of its officers as are responsible for such obligations. Upon
reasonable request, each Master Servicer and each Special Servicer shall furnish
the Depositor and the Trustee with its most recent publicly available annual
audited financial statements (or, if not available, the most recent publicly
available audited annual financial statements of its corporate parent) and such
other information as is publicly available regarding its business, affairs,
property and condition, financial or otherwise; provided that neither the
Depositor nor the Trustee may disclose the contents of such financial statements
or other information to non-affiliated third parties (other than accountants,
attorneys, financial advisors and other representatives retained to help it
evaluate such financial statements or other information), unless it is required
to do so under applicable securities laws or is otherwise compelled to do so as
a matter of law. Each Master Servicer and each Special Servicer may affix to any
such information described in this Section 6.05 provided by it any disclaimer it
deems appropriate in its reasonable discretion. The Depositor may, but is not
obligated to, enforce the obligations of the Master Servicers and Special
Servicers hereunder and may, but is not obligated to, perform, or cause a
designee to perform, any defaulted obligation of the Master Servicers or the
Special Servicers hereunder or exercise the rights of the Master Servicers or
the Special Servicers hereunder; provided, however, that neither of the Master
Servicers nor the Special Servicers shall be relieved of any of its 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 Master Servicers or the Special Servicers and is not
obligated to supervise the performance of the Master Servicers or the Special
Servicers under this Agreement or otherwise.

            Section 6.06 Master Servicers or Special Servicers as Owner of a
Certificate

            Each Master Servicer, each Special Servicer or any Affiliate of any
of them may become the Holder of (or, in the case of a Book-Entry Certificate,
Certificate Owner with respect to) any Certificate with (except as otherwise set
forth in the definition of "Certificateholder") the same rights it would have if
it were not a Master Servicer, a Special Servicer or an Affiliate of any of
them. If, at any time during which a Master Servicer or a Special Servicer or an
Affiliate of a Master Servicer or a Special Servicer is the Holder of (or, in
the case of a Book-Entry Certificate, Certificate Owner with respect to) any
Certificate, such Master Servicer or such Special Servicer, as the case may be,
proposes to take any action (including for this purpose, omitting to take a
particular action) that is not expressly prohibited by the terms hereof and
would not, in such Master Servicer's or such Special Servicer's, as the case may
be, reasonable judgment, violate the Servicing Standard, but that, if taken,
might nonetheless, in such Master Servicer's or such Special Servicer's, as the
case may be, reasonable judgment, be considered by other Persons to violate the
Servicing Standard, then such Master Servicer or such Special Servicer, as the
case may be, may (but need not) seek the approval of the Certificateholders to
such action by delivering to the Trustee a written notice that (a) states that
it is delivered pursuant to this Section 6.06, (b) identifies the Percentage
Interest in each Class of Certificates beneficially owned by such Master
Servicer or such Special Servicer, as the case may be, or by an Affiliate
thereof and (c) describes in reasonable detail the action that such Master
Servicer or such Special Servicer, as the case may be, proposes to take. The
Trustee, upon receipt of such notice, shall forward it to the Certificateholders
(other than a Master Servicer and its Affiliates or a Special Servicer and its
Affiliates, as appropriate), together with a request for approval by the
Certificateholders of each such proposed action. If at any time
Certificateholders holding greater than 50% of the Voting Rights of all
Certificateholders (calculated without regard to the Certificates beneficially
owned by a Master Servicer or its Affiliates or a Special Servicer or its
Affiliates, as the case may be) shall have consented in writing to the proposal
described in the written notice, and if a Master Servicer or a Special Servicer,
as the case may be, shall act as proposed in the written notice, such action
shall be deemed to comply with the Servicing Standard. The Trustee shall be
entitled to reimbursement from such Master Servicer or such Special Servicer, as
applicable, for the reasonable expenses of the Trustee incurred pursuant to this
paragraph. It is not the intent of the foregoing provision that a Master
Servicer or a Special Servicer be permitted to invoke the procedure set forth
herein with respect to routine servicing matters arising hereunder, but rather
in the case of unusual circumstances.

                                  ARTICLE VII

                                     DEFAULT

            Section 7.01 Events of Default

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

            (i) any failure by a Master Servicer to deposit into a Collection
      Account or an A/B Custodial Account any amount required to be so deposited
      under this Agreement, which failure continues unremedied for three
      Business Days following the date on which such deposit was first required
      to be made; or

            (ii) any failure by a Special Servicer to deposit into an REO
      Account or to deposit, or remit to the applicable Master Servicer for
      deposit, into the applicable Master Servicer's Collection Account, any
      amount required to be so deposited or remitted under this Agreement, which
      failure continues unremedied for three Business Days following the date on
      which such deposit or remittance, as the case may be, was first required
      to be made; or

            (iii) any failure by a Master Servicer to remit to the Trustee for
      deposit into the Distribution Account, on any P&I Advance Date, the full
      amount of P&I Advances required to be made by such Master Servicer on such
      date or, on any Master Servicer Remittance Date, the full amount of the
      Master Servicer Remittance Amount and any Compensating Interest Payment
      required to be remitted by such Master Servicer on such date, which
      failure continues unremedied until 6:00 p.m. (New York City time) on such
      P&I Advance Date or Master Servicer Remittance Date, as the case may be;
      or

            (iv) any failure by a Master Servicer to timely make any Servicing
      Advance required to be made by it hereunder, which Servicing Advance
      remains unmade for a period of three Business Days following the date on
      which notice shall have been given to such Master Servicer by the Trustee
      as provided in Section 3.11(f); or

            (v) any failure by a Special Servicer to timely make (or request the
      applicable Master Servicer to make) any Servicing Advance required to be
      made by it hereunder, which Servicing Advance remains unmade for a period
      of three Business Days following the date on which notice has been given
      to such Special Servicer by the Trustee as provided in Section 3.11(f); or

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

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

            (viii) a decree or order of a court or agency or supervisory
      authority having jurisdiction in the premises in an involuntary case under
      any present or future federal or state bankruptcy, insolvency or similar
      law for the appointment of a conservator, receiver, liquidator, trustee or
      similar official in any bankruptcy, insolvency, readjustment of debt,
      marshalling of assets and liabilities or similar proceedings, or for the
      winding-up or liquidation of its affairs, shall have been entered against
      a Master Servicer or Special Servicer and such decree or order shall have
      remained in force undischarged, undismissed or unstayed for a period of 30
      days; provided, however, that, with respect to any such decree or order
      that cannot be discharged, dismissed or stayed within such 30-day period,
      such Master Servicer or Special Servicer, as the case may be, shall have
      an additional period of 30 days to effect such discharge, dismissal or
      stay so long as such Master Servicer or Special Servicer, as the case may
      be, has commenced proceedings to have such decree or order dismissed,
      discharged or stayed within the initial 30-day period and has provided the
      Trustee with an Officer's Certificate certifying that it has diligently
      pursued, and is continuing to pursue, such discharge or stay; or

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

            (x) a Master Servicer or 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

            (xi) Moody's or Fitch has qualified, downgraded or withdrawn its
      rating or ratings of one or more Classes of Certificates, or Moody's has
      placed one or more Classes of Certificates on "watch status" in
      contemplation of possible rating downgrade or withdrawal (and such "watch
      status" placement shall not have been withdrawn by Moody's within 60 days
      of such placement), and, in either case, Moody's has cited servicing
      concerns with a Master Servicer or a Special Servicer as the sole or a
      material factor in such rating action (except that "servicing concerns"
      will be deemed not to be a "material factor" if the applicable Master
      Servicer or Special Servicer establishes to a reasonable degree that the
      rating action would have occurred without regard to those servicing
      concerns); or

            (xii) The NCBFSB Master Servicer shall no longer be rated "CMS3,"
      its equivalent or higher by Fitch and the Co-op Special Servicer shall no
      longer be rated "CSS3," its equivalent or higher by Fitch; or

            (xiii) a Master Servicer is removed from S&P's approved master
      servicer list or a Special Servicer is removed from S&P's approved special
      servicer list, and such Master Servicer or Special Servicer, as the case
      may be, is not restored to such list within 60 days after its removal
      therefrom.

            When a single entity acts as General Master Servicer, NCBFSB Master
Servicer, General Special Servicer and Co-op Special Servicer, or in any two or
more of the foregoing capacities, an Event of Default (other than an event
described in clauses (xi) and (xii) above) in one capacity shall constitute an
Event of Default in both or all such capacities.

            (b) If any Event of Default with respect to a Master Servicer or a
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 the Event of Default shall not have been remedied, the
Depositor and Trustee each may, and at the written direction of either the
Holders of Certificates entitled to not less than 25% of the Voting Rights or
the Controlling Class Representative, the Trustee shall (subject to applicable
bankruptcy or insolvency law in the case of clauses (viii) through (x) of
Section 7.01(a)), terminate, by notice in writing to the Defaulting Party (with
a copy of such notice to each other party hereto), all of the rights and
obligations (accruing from and after such notice) of the Defaulting Party under
this Agreement and in and to the Trust Fund (other than as a Holder of any
Certificate). 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 Mortgage Loans or otherwise, shall pass to and be vested in
the Trustee pursuant to and under this Section, and, without limitation, the
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
and at the expense of the Defaulting Party, as attorney-in-fact or otherwise,
any and all documents and other instruments, and to do or accomplish all other
acts or things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the Mortgage Loans and related documents, or otherwise (provided, however, that
each Master Servicer and each Special Servicer shall, if terminated pursuant to
this Section 7.01(b), continue to be obligated to pay and entitled to receive
all amounts accrued or owing by or to it under this Agreement on or prior to the
date of such termination, whether in respect of Advances or otherwise, including
Workout Fees (as and to the extent provided in Section 3.11(c)), and it and its
members, managers, directors, officers, employees and agents shall continue to
be entitled to the benefits of Section 3.11 and Section 6.03 notwithstanding any
such termination). Each Master Servicer and Special Servicer agrees that, if it
is terminated pursuant to this Section 7.01(b), it shall promptly (and in any
event no later than 20 days subsequent to its receipt of the notice of
termination) provide the Trustee with all documents and records requested
thereby to enable the Trustee to assume such Master Servicer's or Special
Servicer's, as the case may be, functions hereunder, and shall otherwise
cooperate with the Trustee in effecting the termination of such Master
Servicer's or Special Servicer's, as the case may be, responsibilities and
rights hereunder, including the transfer within five Business Days to the
Trustee for administration by it of all cash amounts that at the time are or
should have been credited by such Master Servicer to its Collection Account, any
A/B Custodial Account, the Distribution Account or any Servicing Account or
Reserve Account held by it (if it is the Defaulting Party) or by such Special
Servicer to an REO Account, a Collection Account or any Servicing Account or
Reserve Account held by it (if it is the Defaulting Party) or that are
thereafter received by or on behalf of it with respect to any Mortgage Loan or
REO Property (provided, however, that each Master Servicer and each Special
Servicer shall, if terminated pursuant to this Section 7.01(b), continue to be
obligated to pay and entitled to receive all amounts accrued or owing by or to
it under this Agreement on or prior to the date of such termination, whether in
respect of Advances or otherwise, and it and its members, managers, directors,
officers, employees and agents shall continue to be entitled to the benefits of
Section 6.03 notwithstanding any such termination). Any costs or expenses
(including those of any other party hereto) incurred in connection with any
actions to be taken by a terminated Master Servicer or a Special Servicer
pursuant to this paragraph shall be borne by such Master Servicer or Special
Servicer, as the case may be (and, in the case of the Trustee's costs and
expenses, if not paid within a reasonable time, shall be borne by the Trust out
of the Collection Account).

            Section 7.02 Trustee to Act; Appointment of Successor

            On and after the time any Master Servicer or a Special Servicer
resigns pursuant to Section 6.04(a) or receives a notice of termination pursuant
to Section 7.01, the Trustee shall, subject to Section 3.25, be the successor in
all respects to such Master Servicer or such Special Servicer, as the case may
be, in its capacity as such under this Agreement and the transactions set forth
or provided for herein and shall be subject to all the responsibilities, duties
and liabilities relating thereto and arising thereafter placed on such Master
Servicer or such Special Servicer, as the case may be, by the terms and
provisions hereof, including, if a Master Servicer is the resigning or
terminated party, such Master Servicer's obligation to make Advances; provided,
however, that any failure to perform such duties or responsibilities caused by a
Master Servicer's or a Special Servicer's, as the case may be, failure to
cooperate or to provide information or monies as required by Section 7.01 shall
not be considered a default by the Trustee hereunder. Neither the Trustee nor
any other successor shall be liable for any of the representations and
warranties of the resigning or terminated party or for any losses incurred by
the resigning or terminated party pursuant to Section 3.06 hereunder nor shall
the Trustee or any other successor be required to purchase any Mortgage Loan
hereunder. As compensation therefor, the Trustee shall be entitled to all fees
and other compensation which the resigning or terminated party would have been
entitled to for future services rendered if the resigning or terminated party
had continued to act hereunder. Notwithstanding the above, if it is unwilling to
so act, the Trustee may (and, if it is unable to so act, or if the Trustee is
not approved as an acceptable master servicer or special servicer, as the case
may be, by each Rating Agency, or if the Holders of Certificates entitled to a
majority of all the Voting Rights or the Controlling Class Representative so
request in writing, the Trustee shall), subject to Section 3.25, promptly
appoint, or petition a court of competent jurisdiction to appoint, any
established and qualified institution as the successor to the resigning or
terminated Master Servicer or a Special Servicer, as the case may be, hereunder
in the assumption of all or any part of the responsibilities, duties or
liabilities of such Master Servicer or such Special Servicer, as the case may
be, hereunder; provided, however, that such appointment does not result in an
Adverse Rating Event with respect to any Class of Rated Certificates (as
confirmed in writing to the Trustee by each Rating Agency); and, provided,
further, that such successor is reasonably acceptable to the Controlling Class
Representative. No appointment of a successor to a Master Servicer or a Special
Servicer hereunder shall be effective until the assumption by such successor of
all its responsibilities, duties and liabilities hereunder, and pending such
appointment and assumption, the Trustee shall act in such capacity as
hereinabove provided. In connection with any such appointment and assumption,
the Trustee may make such arrangements for the compensation of such successor
out of payments on the Mortgage Loans or otherwise as it and such successor
shall agree; provided, however, that no such compensation shall be in excess of
that permitted the resigning or terminated party hereunder. The Depositor, the
Trustee, such successor and each other party hereto shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession.

            If the Trustee or an Affiliate acts pursuant to this Section 7.02 as
successor to a Master Servicer, it may reduce the related Excess Servicing Fee
Rate to the extent that its or such Affiliate's compensation as successor to
such Master Servicer would otherwise be below the market rate servicing
compensation. If the Trustee elects to appoint a successor to a Master Servicer
other than itself or an Affiliate pursuant to this Section 7.02, it may reduce
the related Excess Servicing Fee Rate to the extent reasonably necessary (in the
sole discretion of the Trustee) for the Trustee to appoint a qualified successor
to such Master Servicer that meets the requirements of this Section 7.02.

            Section 7.03 Notification to Certificateholders

            (a) Upon any resignation of a Master Servicer or Special Servicer
pursuant to Section 6.04, any termination of a Master Servicer or such Special
Servicer pursuant to Section 7.01, any appointment of a successor to such Master
Servicer or such Special Servicer pursuant to Section 6.02, 6.04 or 7.02 or the
effectiveness of any designation of a new Special Servicer pursuant to Section
3.25, the Trustee shall give prompt written notice thereof to Certificateholders
at their respective addresses appearing in the Certificate Register and, to the
extent such information has been made available to the Trustee, to any B Loan
Holder and the Washington Center Junior Holders.

            (b) Not later than the later of (i) 60 days after the occurrence of
any event which constitutes or, with notice or lapse of time or both, would
constitute an Event of Default and (ii) five days after a Responsible Officer of
the Trustee has actual knowledge of the occurrence of such an event, the Trustee
shall transmit by mail to the Depositor and all Certificateholders notice of
such occurrence, and the Depositor shall send to any B Loan Holder and the
Washington Center Junior Holders 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% of the
Voting Rights allocated to each Class of Certificates affected by any Event of
Default hereunder may waive such Event of Default; provided that an Event of
Default under clause (i), clause (ii), clause (iii), clause (xi), clause (xii)
or clause (xiii) of Section 7.01(a) may be waived only by all of the
Certificateholders of the affected Classes. Upon any such waiver of an Event of
Default, and payment to the Trustee of all reasonable costs and expenses
incurred by the Trustee in connection with such default prior to its waiver
(which costs shall be paid by the party requesting such 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 registered in the name of any other Person.

            Section 7.05 Additional Remedies of Trustee Upon Event of Default

            During the continuance of any Event of Default, so long as such
Event of Default shall not have been remedied, the Trustee, in addition to the
rights specified in Section 7.01, shall have the right (exercisable subject to
Section 8.01(a)), in its own name and as trustee of an express trust, to take
all actions now or hereafter existing at law, in equity or by statute to enforce
its rights and remedies and to protect the interests, and enforce the rights and
remedies, of the Certificateholders (including the institution and prosecution
of all judicial, administrative and other proceedings and the filings of proofs
of claim and debt in connection therewith). Except as otherwise expressly
provided in this Agreement, no remedy provided for by this Agreement shall be
exclusive of any other remedy, and each and every remedy shall be cumulative and
in addition to any other remedy, and no delay or omission to exercise any right
or remedy shall impair any such right or remedy or shall be deemed to be a
waiver of any Event of Default.

            Section 7.06 Replacement of Great Lakes Crossing Special Servicer

            Provided the relevant Controlling Class Representative under the
Series 2003-CK2 Trust has not replaced the Great Lakes Crossing Special
Servicer, the Trustee may (and, at the direction of the Controlling Class
Representative or of Certificateholders representing at least 25% of the Voting
Rights, shall) consent to the termination and replacement of, or exercise such
rights as may be granted to it under the Great Lakes Crossing Intercreditor
Agreement and/or any Great Lakes Crossing Servicing Agreement to terminate and
replace, the Great Lakes Crossing Special Servicer; provided that the Trustee
shall first obtain written confirmation from each Rating Agency that its
granting such consent or exercising such rights shall not result in an Adverse
Rating Event with respect to any Class of Rated Certificates. The Trustee and
the Master Servicer shall each notify the other such party, the
Certificateholders, the Controlling Class Representative and the Rating Agencies
of any Series 2003-CK2 Event of Default known to a Responsible Officer of the
Trustee or a Servicing Officer of the Master Servicer, as the case may be, in
the same manner as it would notify such parties of an Event of Default
hereunder.

                                  ARTICLE VIII

                                   THE TRUSTEE

            Section 8.01 Duties of Trustee

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

            (b) 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), the Trustee 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 take such action as it deems
appropriate to have the instrument corrected. The Trustee shall not be
responsible or liable for the accuracy or content of any resolution,
certificate, statement, opinion, report, document, order or other instrument
furnished by the Depositor, the Master Servicers, the Special Servicers, any
actual or prospective Certificateholder or Certificate Owner or either Rating
Agency, 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 or waiver of all 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%
      (or, as to any particular matter, any higher percentage as may be
      specifically provided for hereunder) 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.

            (iv) The Trustee shall not be required to take action with respect
      to, or be deemed to have notice or knowledge of, any default or Event of
      Default (except an Event of Default under Section 7.01(a)(xi), Section
      7.01(a)(xii) or Section 7.01(a)(xiii) or the Master Servicer's failure to
      deliver any monies, including P&I Advances, or to provide any report,
      certificate or statement, to the Trustee when required pursuant to this
      Agreement) unless a Responsible Officer of the Trustee shall have received
      written notice or otherwise have actual knowledge thereof. Otherwise, the
      Trustee may conclusively assume that there is no such default or Event of
      Default.

            (v) 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 as expressly provided in Section 2.01(c) or Section 2.01(e)
      or in its capacity as a successor Master Servicer or successor Special
      Servicer, (A) to cause 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 cause the
      maintenance of any such recording or filing or depositing or to any
      re-recording, refiling or redepositing of any thereof, (B) to cause the
      maintenance of any insurance, and (C) to confirm or verify the truth,
      accuracy or contents of any reports or certificates of a Master Servicer,
      a Special Servicer, any actual or prospective or any Certificateholder or
      Certificate Owner or either Rating Agency, delivered to the Trustee
      pursuant to this Agreement reasonably believed by the Trustee to be
      genuine and without error and to have been signed or presented by the
      proper party or parties.

            (vi) For as long as the Person that serves as Trustee hereunder also
      serves as a Custodian or as Certificate Registrar, the protections,
      immunities and indemnities afforded to the Trustee hereunder shall also be
      afforded to such Person in its capacity as Custodian and/or Certificate
      Registrar, as the case may be.

            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, Officers' 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 without
      error and to have been signed or presented by the proper party or parties;

            (ii) the Trustee may consult with counsel and any written advice or
      opinion of such 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, 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; provided, however, that nothing contained herein shall
      relieve the Trustee of the obligation, upon the occurrence of an Event of
      Default which has not been waived or 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) neither the Trustee nor any Fiscal Agent appointed thereby
      shall be personally liable for any action reasonably taken, suffered or
      omitted by it in good faith and believed by it to be authorized or within
      the discretion or rights or powers conferred upon it by this Agreement;

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

            (vi) except as contemplated by Section 8.06, the Trustee shall not
      be required to give any bond or surety in respect of the execution of the
      trusts created hereby or the powers granted hereunder;

            (vii) the Trustee may execute any of the trusts or powers vested in
      it by this Agreement or perform any of its duties hereunder either
      directly or by or through agents or attorneys-in-fact, provided that the
      use of agents or attorneys-in-fact shall not be deemed to relieve the
      Trustee of any of its duties and obligations hereunder (except as
      expressly set forth herein);

            (viii) neither the Trustee nor any Fiscal Agent appointed thereby
      shall be responsible for any act or omission of a Master Servicer or a
      Special Servicer (unless the Trustee is acting as such Master Servicer or
      such Special Servicer, as the case may be) or of the Depositor.

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

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

            The recitals contained herein and in the Certificates (other than
the statements attributed to, and the representations and warranties of, the
Trustee and/or any Fiscal Agent in Article II, and the signature of the Trustee
set forth on each outstanding Certificate) shall not be taken as the statements
of the Trustee or any Fiscal Agent, and neither the Trustee nor any Fiscal Agent
assumes any responsibility for their correctness. Neither the Trustee nor any
Fiscal Agent makes any representation as to the validity or sufficiency of this
Agreement (except as regards the enforceability of this Agreement against it) or
of any Certificate (other than as to the signature of the Trustee set forth
thereon) or of any Mortgage Loan or related document. Neither the Trustee nor
any Fiscal Agent shall be accountable for the use or application by the
Depositor of any of the Certificates issued to it or of the proceeds of such
Certificates, or for the use or application of any funds paid to the Depositor
in respect of the assignment of the Mortgage Loans to the Trust, or any funds
deposited in or withdrawn from the Collection Account or any other account by or
on behalf of the Depositor, the Master Servicers or the Special Servicers (in
each case, unless the Trustee is acting in such capacity). Neither the Trustee
nor any Fiscal Agent shall be responsible for the legality or validity of this
Agreement (other than insofar as it relates to the obligations of the Trustee or
such Fiscal Agent, as the case may be, hereunder) or the validity, priority,
perfection or sufficiency of any security, lien or security interest granted to
it hereunder or the filing of any financing statements or continuation
statements, except to the extent set forth in Section 2.01(c) and Section
2.01(e) or to the extent the Trustee is acting as a Master Servicer or Special
Servicer and such Master Servicer or Special Servicer, as the case may be, would
be so responsible hereunder. The Trustee shall not be required to record this
Agreement, except as provided in Section 11.02(a).

            Section 8.04 Trustee and Fiscal Agent May Own Certificates

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

            Section 8.05 Fees and Expenses of Trustee; Indemnification of and by
Trustee and Fiscal Agent

            (a) On each Distribution Date, the Trustee shall withdraw from the
Distribution Account, prior to any distributions to be made therefrom to
Certificateholders on such date, and pay to itself all earned but unpaid
Trustee's Fees in respect of the Mortgage Loans and any REO Mortgage Loans
through the end of the most recently ended calendar month, as compensation for
all services rendered by the Trustee in the execution of the trusts hereby
created and in the exercise and performance of any of the powers and duties of
the Trustee hereunder. As to each Mortgage Loan and REO Mortgage Loan, the
Trustee's Fee shall accrue during each calendar month, commencing with May 2003,
at the Trustee's Fee Rate on a principal amount equal to the Stated Principal
Balance of such Mortgage Loan or REO Mortgage Loan immediately following the
Distribution Date in such calendar month (or, in the case of May 2003, on a
principal amount equal to the Cut-off Date Principal Balance of the particular
Mortgage Loan), whether or not interest is actually collected on each Mortgage
Loan and REO Mortgage Loan. With respect to each Mortgage Loan and REO Mortgage
Loan, the Trustee's Fee shall accrue from time to time on the same Interest
Accrual Basis as is applicable to such Mortgage Loan or REO Mortgage Loan.
Except as otherwise expressly provided herein, the Trustee's Fees (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) shall constitute the Trustee's sole compensation
for such services to be rendered by it. The Trustee shall also be entitled to
all interest or other income earned on deposits in the Accounts maintained by
the Trustee, in accordance with Section 3.06(b) (but only to the extent of the
Net Investment Earnings, if any, with respect to any such Account for each
Collection Period).

            (b) The Trustee and any director, officer, employee or agent of the
Trustee shall be entitled to be indemnified and held harmless out of the Trust
Fund for and against any loss, liability, claim or expense (including costs and
expenses of litigation, and of investigation, counsel fees, damages, judgments
and amounts paid in settlement) arising out of, or incurred in connection with,
this Agreement, the Certificates, the Mortgage Loans (unless it incurs any such
expense or liability in the capacity of a successor Master Servicer or Special
Servicer, in which case such expense or liability will be reimbursable thereto
in the same manner as it would be for any other Person acting as such Master
Servicer or Special Servicer, as the case may be) 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, if (but only if) such loss, liability, claim or
expense constitutes an "unanticipated expense" within the meaning of Treasury
Regulations Section 1.860G-1(b)(3)(ii); 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(b) for (1) allocable overhead,
such as costs for office space, office equipment, supplies and related expenses,
employee salaries and related expenses and similar internal costs and expenses,
(2) any expense or liability specifically required to be borne thereby pursuant
to the terms hereof or (3) any loss, liability, claim or expense incurred by
reason of any breach on the part of the Trustee of any of its representations,
warranties or covenants contained herein or any willful misfeasance, bad faith
or negligence in the performance of, or reckless disregard of, the Trustee's
obligations and duties hereunder.

            (c) Each Master Servicer and each Special Servicer shall indemnify
the Trustee and any Fiscal Agent for and hold each of them harmless against any
loss, liability, claim or expense that is a result of such Master Servicer's or
such Special Servicer's, as the case may be, negligent acts or omissions in
connection with this Agreement, including the negligent use by such Master
Servicer or such Special Servicer, as the case may be, of any powers of attorney
delivered to it by the Trustee pursuant to the provisions hereof and the
Mortgage Loans serviced by such Master Servicer or such Special Servicer, as the
case may be; provided, however, that, if the Trustee has been reimbursed for
such loss, liability, claim or expense pursuant to Section 8.05(b), or any
Fiscal Agent has been reimbursed for such loss, liability, claim or expense
pursuant to Section 8.13, then the indemnity in favor of such Person provided
for in this Section 8.05(c) with respect to such loss, liability, claim or
expense shall be for the benefit of the Trust.

            (d) Each of the Trustee and any Fiscal Agent shall indemnify the
Master Servicers and the Special Servicers for and hold each of them harmless
against any loss, liability, claim or expense that is a result of the Trustee's
or such Fiscal Agent's, as the case may be, negligent acts or omissions in
connection with this Agreement; provided, however, that if either Master
Servicer or either Special Servicer has been reimbursed for such loss,
liability, claim or expense pursuant to Section 6.03, then the indemnity in
favor of such Person provided for in this Section 8.05(d) with respect to such
loss, liability, claim or expense shall be for the benefit of the Trust.

            (e) This Section 8.05 shall survive the termination of this
Agreement or the resignation or removal of the Trustee, any Fiscal Agent, either
Master Servicer or either Special Servicer as regards rights and obligations
prior to such termination, resignation or removal.

            Section 8.06 Eligibility Requirements for Trustee

            The Trustee hereunder shall at all times be a corporation, bank,
trust company or association organized and doing business under the laws of the
United States of America or any State thereof or the District of Columbia,
authorized under such laws to exercise trust powers, having a combined capital
and surplus of at least $50,000,000 and subject to supervision or examination by
federal or state authority. If such corporation, bank, trust company or
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, bank, trust company or association shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. In addition, the Trustee shall at all times meet the requirements
of Section 26(a)(1) of the Investment Company Act, and the affiliations of the
Trustee shall not adversely affect the availability of PTE 89-90 with respect to
any Class of investment grade rated Certificates. Furthermore, the Trustee shall
at all times maintain a long-term unsecured debt rating of no less than "Aa3"
from Moody's and "AA" from S&P and Fitch (or, in the case of either Rating
Agency, such lower rating as will not result in an Adverse Rating Event with
respect to any Class of Rated Certificates, as confirmed in writing to the
Trustee and the Depositor by such Rating Agency); provided that the Trustee
shall not cease to be eligible to serve as such based on a failure to satisfy
such rating requirements so long as the Trustee maintains a long-term unsecured
debt rating of no less than "BBB" from S&P and Fitch (or, in the case of either
Rating Agency, such lower rating as will not result in an Adverse Rating Event
with respect to any Class of Rated Certificates, as confirmed in writing to the
Trustee and the Depositor by such Rating Agency) and a Fiscal Agent meeting the
requirements of Section 8.13 has been appointed by the Trustee and is then
currently serving in such capacity. In case at any time the Trustee shall cease
to be eligible in accordance with the provisions of this Section 8.06, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 8.07. The corporation, bank, trust company or association serving as
Trustee may have normal banking and trust relationships with the Depositor, any
Mortgage Loan Seller, either Master Servicer, either Special Servicer and their
respective Affiliates; provided, however, that none of (i) the Depositor, (ii)
any Person involved in the organization or operation of the Depositor or the
Trust, (iii) either Master Servicer or either Special Servicer (except during
any period when the Trustee has assumed the duties of a Master Servicer or a
Special Servicer, as the case may be, pursuant to Section 7.02), (iv) any
Mortgage Loan Seller or (v) any Affiliate of any of them, may be the Trustee
hereunder.

            Section 8.07 Resignation and Removal of Trustee

            (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Controlling Class Representative, the Master Servicers, the Special Servicers,
the Certificateholders and any B Loan Holder. Upon receiving such notice of
resignation, the Depositor shall promptly appoint a successor trustee reasonably
acceptable to the Controlling Class Representative meeting the eligibility
requirements of Section 8.06, 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 other parties hereto
and to the Certificateholders and any B Loan Holders 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.

            (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor or the Master Servicers or if at any
time the Trustee shall become incapable of acting, or shall be adjudged bankrupt
or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, or if the Trustee's continuing to act in such capacity would (as
confirmed in writing to any party hereto by either Rating Agency) result in an
Adverse Rating Event with respect to any Class of Rated Certificates, then the
Depositor may (and, if it fails to do so within ten Business Days, the General
Master Servicer shall as soon as practicable) remove the Trustee and appoint a
successor trustee 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 other parties hereto and to the
Certificateholders by the Depositor (or the General Master Servicer, as the case
may be).

            (c) The Holders of Certificates entitled to not less than 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 Depositor (with copies to the Master Servicers and the
Special Servicers), one complete set to the Trustee so removed and one complete
set to the successor so appointed. All expenses incurred by the Trustee in
connection with its transfer of the Mortgages Files to a successor trustee
following the removal of the Trustee without cause pursuant to this Section
8.07(c), shall be reimbursed to the removed Trustee within 30 days of demand
therefor, such reimbursement to be made by the Certificateholders that
terminated the Trustee. A copy of such instrument shall be delivered to the
other parties hereto and to the remaining Certificateholders and B Loan Holders
by the successor so appointed.

            (d) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
not become effective until (i) acceptance of appointment by the successor
trustee as provided in Section 8.08 and (ii) if neither the successor trustee
nor any Fiscal Agent appointed by it has a long-term unsecured debt rating of at
least "Aa3" from Moody's and "AA" from S&P and Fitch, the Trustee and the
Depositor have received written confirmation from each Rating Agency that has
not so assigned such a rating, to the effect that the appointment of such
successor trustee shall not result in an Adverse Rating Event with respect to
any Class of Rated Certificates.

            Section 8.08 Successor Trustee

            (a) Any successor trustee appointed as provided in Section 8.07
shall execute, acknowledge and deliver to the Depositor, the Master Servicers
and the Special Servicers and its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor hereunder, with the
like effect as if originally named as trustee herein. The predecessor trustee
shall deliver to the successor trustee all Mortgage Files and related documents
and statements held by it hereunder (other than any Mortgage Files at the time
held on its behalf by a Custodian, which Custodian shall become the agent of the
successor trustee), and the Depositor, the Master Servicers, the Special
Servicers 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, such successor trustee shall mail notice of the
succession of such trustee hereunder to the Depositor and the Certificateholders
and the B Loan Holders.

            Section 8.09 Merger or Consolidation of Trustee

            Any entity into which the Trustee may be merged or converted or with
which it may be consolidated or any entity resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any entity succeeding
to the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such entity 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.

            Section 8.10 Appointment of Co-Trustee or Separate Trustee

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

            (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 when acting as a Master Servicer or a 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 Custodians

            The Trustee may, upon prior written notice to the General Master
Servicer, General Special Servicer, NCBFSB Master Servicer and Co-op Special
Servicer, appoint at the Trustee's own expense one or more Custodians to hold
all or a portion of the Mortgage Files as agent for the Trustee; provided that
each Custodian shall be a depository institution supervised and regulated by a
federal or state banking authority, shall have combined capital and surplus of
at least $10,000,000, shall be qualified to do business in the jurisdiction in
which it holds any Mortgage File, shall not be the Depositor, any Mortgage Loan
Seller or any Affiliate of the Depositor or any Mortgage Loan Seller, and shall
have in place a fidelity bond and errors and omissions policy, each in such form
and amount as is customarily required of custodians acting on behalf of Freddie
Mac or Fannie Mae. Each Custodian shall be subject to the same obligations,
standard of care, protection and indemnities as would be imposed on, or would
protect, the Trustee hereunder in connection with the retention of Mortgage
Files directly by the Trustee. The appointment of one or more Custodians shall
not relieve the Trustee from any of its obligations hereunder, and the Trustee
shall remain responsible for all acts and omissions of any Custodian.

            Section 8.12 Access to Certain Information

            (a) The Trustee shall afford to the Depositor, the Master Servicers,
the Special Servicers, the Controlling Class Representative, any B Loan Holder,
and each Washington Center Junior Holder (but only to the extent such
information relates to the related Mortgage Loan, Mortgaged Property or
Borrower) and each Rating Agency and to the OTS, the FDIC and any other banking
or insurance regulatory authority that may exercise authority over any
Certificateholder or Certificate Owner, access to any documentation regarding
the Mortgage Loans or the other assets of the Trust Fund that are in its
possession or within its control. Such access shall be afforded without charge
but only upon reasonable prior written request and during normal business hours
at the offices of the Trustee designated by it.

            (b) The Trustee shall maintain at its offices and, upon reasonable
prior written request and during normal business hours, shall make available for
review by the Depositor, the Underwriters, the Rating Agencies, the Controlling
Class Representative and, subject to the succeeding paragraph, any
Certificateholder, each B Loan Holder and its designees, and each Washington
Center Junior Holder (but only to the extent such information relates to the
related Mortgage Loan, Mortgaged Property or Borrower), Certificate Owner or
Person identified to the Trustee as a prospective Transferee of a Certificate or
an interest therein, originals and/or copies of the following items (to the
extent such items were prepared by or delivered to the Trustee): (i) the
Prospectus, the Confidential Offering Circular and any other disclosure document
relating to the Certificates, in the form most recently provided to the Trustee
by the Depositor or by any Person designated by the Depositor; (ii) this
Agreement, each Mortgage Loan Purchase Agreement, any amendment to any such
agreement, each Sub-Servicing Agreement delivered to the Trustee since the

recent quarterly and annual operating statement and rent roll (for Mortgaged
Properties other than residential cooperative properties) of each related

pursuant to Section 3.12(b) or this Section 8.12(b); (viii) any and all notices
and reports delivered to the Trustee with respect to any Mortgaged Property as
to which the environmental testing contemplated by Section 3.09(c) revealed that
neither of the conditions set forth in clauses (i) and (ii) of the first
sentence thereof was satisfied; (ix) each of the Mortgage Files, including any
and all modifications, waivers and amendments of the terms of a Mortgage Loan
entered into or consented to by a Master Servicer or a Special Servicer and
delivered to the Trustee pursuant to Section 3.20; (x) the most recent Appraisal
for each Mortgage Loan and REO Property that has been delivered to the Trustee
(all Appraisals of Mortgaged Properties and/or REO Properties shall be delivered
to the Trustee by the applicable Master Servicer or Special Servicer, as
applicable, promptly following the subject Appraisal's having been obtained or
formulated); (xi) any and all Officer's Certificates and other evidence
delivered to or by the Trustee to support its, a Master Servicer's, a Special
Servicer's or any Fiscal Agent's, as the case may be, determination that any
Advance was (or, if made, would be) a Nonrecoverable Advance; (xii) a current
report from the Trustee listing all outstanding exceptions to the Mortgage File
review conducted pursuant to Section 2.02; and (xiii) any other information that
may be necessary to satisfy the requirements of subsection (d)(4)(i) of Rule
144A under the Securities Act. The Trustee shall provide copies of any and all
of the foregoing items upon request of any of the parties set forth in the
previous sentence; however, except in the case of the Rating Agencies and the
Controlling Class Representative, the Trustee shall be permitted to require
payment of a sum sufficient to cover the reasonable costs and expenses of
providing such copies. If necessary, the Trustee shall request from the Master
Servicers, and within a reasonable period following its receipt of such request,
and the Master Servicers shall deliver, copies of the items listed in clauses
(vi) and (vii) above to the Trustee.

            In connection with providing access to or copies of the items
described in the preceding paragraph pursuant to this Section 8.12(b), the
Trustee shall require: (a) in the case of Certificateholders or Certificate
Owners, a written confirmation executed by the requesting Person substantially
in the form of Exhibit K 1 hereto (or such other form as may be reasonably
acceptable to the Trustee) generally to the effect that such Person is a holder
or a beneficial holder of Certificates and, subject to the last sentence of this
paragraph, will keep such information confidential, except that such
Certificateholder or Certificate Owner may provide such information to its
auditors, legal counsel and regulators and to any other Person that holds or is
contemplating the purchase of any Certificate or interest therein (provided that
such other Person confirms in writing such ownership interest or prospective
ownership interest and agrees to keep such information confidential); and (b) in
the case of a prospective purchaser of a Certificate or an interest therein,
confirmation executed by the requesting Person substantially in the form of
Exhibit K-2 hereto (or such other form as may be reasonably acceptable to the
Trustee) generally to the effect that such Person is a prospective purchaser of
a Certificate or an interest therein, is requesting the information for use in
evaluating a possible investment in Certificates and, subject to the last
sentence of this paragraph, will otherwise keep such information confidential.
Notwithstanding the foregoing, no Certificateholder, Certificate Owner or
prospective Certificateholder or Certificate Owner need keep confidential any
information received from the Trustee pursuant to this Section 8.12(b) that has
previously been filed with the Commission, and the Trustee shall not require
either of the certifications contemplated by the second preceding sentence in
connection with providing any information pursuant to this Section 8.12(b) that
has previously been filed with the Commission.

            (c) None of the Trustee, either Master Servicer or either Special
Servicer shall be liable for providing or disseminating information in
accordance with the terms of this Agreement.

            Section 8.13 Appointment of Fiscal Agent

            (a) Insofar as the Trustee would not otherwise satisfy the rating
requirements of Section 8.06, the Trustee may appoint, at the Trustee's own
expense, a Fiscal Agent for purposes of making Advances hereunder that are
otherwise required to be made by the Trustee. Any Fiscal Agent shall at all
times maintain a long-term unsecured debt rating of no less than "Aa3" from
Moody's and "AA" from S&P and Fitch (or, in the case of either Rating Agency,
such lower rating as will not result in an Adverse Rating Event with respect to
any Class of Rated Certificates (as confirmed in writing to the Trustee and the
Depositor by such Rating Agency)). Any Person so appointed by the Trustee
pursuant to this Section 8.13(a) shall become the Fiscal Agent on the date as of
which the Trustee and the Depositor have received: (i) if the long-term
unsecured debt of the designated Person is not rated at least "Aa3" by Moody's
and "AA" by S&P and Fitch, written confirmation from each Rating Agency that the
appointment of such designated Person will not result in an Adverse Rating Event
with respect to any Class of Rated Certificates; (ii) a written agreement
whereby the designated Person is appointed as, and agrees to assume and perform
the duties of, Fiscal Agent hereunder, executed by such designated Person and
the Trustee (such agreement, the "Fiscal Agent Agreement"); and (iii) an Opinion
of Counsel (which shall be paid for by the designated Person or the Trustee)
substantially to the effect that (A) the appointment of the designated Person to
serve as Fiscal Agent is in compliance with this Section 8.13, (B) the
designated Person is duly organized, validly existing and in good standing under
the laws of the jurisdiction of its organization, (C) the related Fiscal Agent
Agreement has been duly authorized, executed and delivered by the designated
Person and (D) upon execution and delivery of the related Fiscal Agent
Agreement, the designated Person shall be bound by the terms of this Agreement
and, subject to customary bankruptcy and insolvency exceptions and customary
equity exceptions, that this Agreement shall be enforceable against the
designated Person in accordance with its terms. Any Person that acts as Fiscal
Agent shall, for so long as it so acts, be deemed a party to this Agreement for
all purposes hereof. Pursuant to the related Fiscal Agent Agreement, each Fiscal
Agent, if any, shall make representations and warranties with respect to itself
that are comparable to those made by the Trustee pursuant to Section 2.09.
Notwithstanding anything contained in this Agreement to the contrary, any Fiscal
Agent shall be entitled to all limitations on liability, rights of reimbursement
and indemnities to which the Trustee is entitled hereunder (including pursuant
to Sections 8.05(b) and 8.05(c)) as if it were the Trustee.

            (b) To the extent that the Trustee is required, pursuant to the
terms of this Agreement, to make any Advance, whether as a successor Master
Servicer or otherwise, and has failed to do so in accordance with the terms
hereof, the Fiscal Agent (if any) shall make such Advance when and as required
by the terms of this Agreement on behalf the Trustee as if such Fiscal Agent
were the Trustee hereunder. To the extent that the Fiscal Agent (if any) makes
an Advance pursuant to this Section 8.13 or otherwise pursuant to this
Agreement, the obligations of the Trustee under this Agreement in respect of
such Advance shall be satisfied.

            (c) Notwithstanding anything contained in this Agreement to the
contrary, any Fiscal Agent shall be entitled to all limitations on liability,
rights of reimbursement and indemnities to which the Trustee is entitled
hereunder (including pursuant to Sections 8.05(b) and 8.05(c)) as if it were the
Trustee, except that all fees and expenses of any Fiscal Agent (other than
interest owed to such Fiscal Agent in respect of unreimbursed Advances) incurred
by such Fiscal Agent in connection with the transactions contemplated by this
Agreement shall be borne by the Trustee, and neither the Trustee nor such Fiscal
Agent shall be entitled to reimbursement therefor from any of the Trust, the
Depositor, the Master Servicers or the Special Servicers.

            (d) The obligations of any Fiscal Agent set forth in this Section
8.13 or otherwise pursuant to this Agreement shall exist only for so long as the
Trustee that appointed it shall act as Trustee hereunder. Any Fiscal Agent may
resign or be removed by the Trustee only if and when the existence of such
Fiscal Agent is no longer necessary for such Trustee to satisfy the eligibility
requirements of Section 8.06; provided that any Fiscal Agent shall be deemed to
have resigned at such time as the Trustee that appointed it resigns or is
removed as Trustee hereunder (in which case the responsibility for appointing a
successor Fiscal Agent in accordance with this Section 8.13(a) shall belong to
the successor Trustee insofar as such appointment is necessary for such
successor Trustee to satisfy the eligibility requirements of Section 8.06).

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

            Section 8.14 Filings with the Securities and Exchange Commission

            (a) With respect to the Trust's fiscal year 2003 (and, if as of the
beginning of any other fiscal year for the Trust, the Registered Certificates
are held (directly or, in the case of Registered Certificates held in book-entry
form, through the Depository) by at least 300 Holders and/or Depository
Participants having accounts with the Depository), the Trustee shall:

            (i) during such fiscal year, in accordance with the Exchange Act,
      the rules and regulations promulgated thereunder and applicable "no-action
      letters" issued by the Commission, prepare for filing, execute and
      properly file with the Commission monthly, with respect to the Trust, a
      Current Report on Form 8-K with copies of the Trustee Reports;

            (ii) during such fiscal year, (A) monitor for and promptly notify
      the Depositor of the occurrence or existence of any of the matters
      identified in Section 11.09(a) and/or Section 8.14(b) (in each case to the
      extent that a Responsible Officer of the Trustee has actual knowledge
      thereof), (B) cooperate with the Depositor in obtaining all necessary
      information in order to enable the Depositor to prepare a Current Report
      on Form 8-K reporting any such matter in accordance with the Exchange Act,
      the rules and regulations promulgated thereunder and applicable "no-action
      letters" issued by the Commission, and (C) execute and promptly file with
      the Commission any such Current Report on Form 8-K prepared by or on
      behalf of the Depositor and delivered to the Trustee; and

            (iii) prepare, execute and properly file with the Commission on or
      before the due date specified by the Commission, with respect to the
      Trust, an Annual Report on Form 10-K which complies in all material
      respects with the requirements of the Exchange Act, the rules and
      regulations promulgated thereunder and applicable "no-action letters"
      issued by the Commission, which shall include as exhibits the Annual
      Performance Certification and Annual Accountant's Report delivered
      pursuant to Section 3.13 and Section 3.14, respectively, with respect to
      the Master Servicers and the Special Servicers for such fiscal year, and
      which shall further include such certification(s) as may be required under
      the Sarbanes-Oxley Act of 2002 (the "Sarbanes Act") and any rules
      promulgated by, or interpretive guidance from, the Commission (such
      certification(s), individually and collectively, insofar as they are
      required to be part of any particular Annual Report on Form 10-K, a
      "Sarbanes-Oxley Certification") (which Sarbanes-Oxley Certifications shall
      be signed by the party or parties contemplated by this Section 8.14);

provided that (x) the Trustee shall not have any responsibility to file any
items (other than those generated by it) that have not been received in a format
suitable for electronic filing via the EDGAR system (or in "ASCII", "Microsoft
Word", "Microsoft Excel" or another format reasonably acceptable to the Trustee)
and shall not have any responsibility to convert any such items to such format
(other than those items generated by it and those items delivered to it in a
format readily convertible to a format suitable for electronic filing via the
EDGAR system) and (y) the Depositor shall be responsible for preparing,
executing and filing (via the EDGAR system within 15 days following the Closing
Date) a Current Report on Form 8-K reporting the establishment of the Trust and
whereby this Agreement is filed as an exhibit. Each of the other parties to this
Agreement shall deliver to the Trustee or the applicable Master Servicer, as
applicable, in a format suitable for electronic filing via the EDGAR system (or
in "ASCII", "Microsoft Word", "Microsoft Excel" or another format reasonably
acceptable to the Trustee) any and all items contemplated to be filed with the
Commission pursuant to this Section 8.14(a), to the extent it is otherwise
required to deliver such items to the Trustee or the applicable Master Servicer,
as applicable.

            (b) At all times during the Trust's fiscal year 2003 (and, if as of
the beginning of any other fiscal year for the Trust, the Registered
Certificates are held (directly or, in the case of Registered Certificates held
in book-entry form, through the Depository) by at least 300 Holders and/or
Depository Participants having accounts with the Depository, at all times during
such other fiscal year), the Trustee shall monitor for and promptly notify the
Depositor of the occurrence or existence of any of the following matters of
which a Responsible Officer of the Trustee has actual knowledge:

            (i) any failure of the Trustee to make any monthly distributions to
      the Holders of any Class of Certificates, which failure is not otherwise
      reflected in the Certificateholder Reports filed with the Commission or
      has not otherwise been reported to the Depositor pursuant to any other
      Section of this Agreement;

            (ii) any acquisition or disposition by the Trust of a Mortgage Loan
      or an REO Property (or, in the case of any Great Lakes Crossing REO
      Property, any interest therein), which acquisition or disposition has not
      otherwise been reflected in the Certificateholder Reports filed with the
      Commission or has not otherwise been reported to the Depositor pursuant to
      any other Section of this Agreement;

            (iii) any other acquisition or disposition by the Trust of a
      significant amount of assets (other than Permitted Investments, Mortgage
      Loans and REO Properties), other than in the normal course of business;

            (iv) any change in the fiscal year of the Trust;

            (v) any material legal proceedings, other than ordinary routine
      litigation incidental to the business of the Trust, to which the Trust (or
      any party to this Agreement on behalf of the Trust) is a party or of which
      any property included in the Trust Fund is subject, or any threat by a
      governmental authority to bring any such legal proceedings;

            (vi) any event of bankruptcy, insolvency, readjustment of debt,
      marshalling of assets and liabilities, or similar proceedings in respect
      of or pertaining to the Trust or any party to this Agreement, or any
      actions by or on behalf of the Trust or any party to this Agreement
      indicating its bankruptcy, insolvency or inability to pay its obligations;
      and

            (vii) any change in the rating or ratings assigned to any Class of
      Certificates not otherwise reflected in the Certificateholder Reports
      filed with the Commission;

provided that (x) the actual knowledge of a Responsible Officer of the Trustee
of any material legal proceedings of which property included in the Trust Fund
is subject or of any material legal proceedings threatened by a governmental
authority is limited to circumstances where it would be reasonable for the
Trustee to identify such property as an asset of, or as securing an asset of,
the Trust or such threatened proceedings as concerning the Trust and (y) no
Responsible Officer of the Trustee shall be deemed to have actual knowledge of
the matters described in clauses (vi) and (vii) of this Section 8.14(b) unless
such Responsible Officer was notified in writing.

            (c) The Form 10-K shall include the Sarbanes-Oxley Certification
required to be included therewith pursuant to the Sarbanes Act, and the rules
and regulations of the Commission promulgated thereunder (including any
interpretations thereof by the Commission's staff) and a copy of such
Sarbanes-Oxley Certification shall be provided to the Rating Agencies. An
officer of the Depositor shall sign the Sarbanes-Oxley Certification. The
Depositor hereby grants to the Trustee a limited power of attorney to execute
and file such annual report on Form 10-K on behalf of the Depositor, which power
of attorney shall continue until the earlier of (i) receipt by the Trustee from
the Depositor of written notice terminating such power of attorney or (ii) the
termination of the Trust. The Master Servicers, the Special Servicers and the
Trustee (each, a "Performing Party") shall provide to the Person who signs the
Sarbanes-Oxley Certification (the "Certifying Person") a certification (each, a
" Performance Certification"), in the form set forth on Exhibit P hereto (with
respect to the Master Servicers and the Trustee) or in the form set forth on
Exhibit A to Exhibit P hereto (with respect to the Special Servicers), as
applicable, on which the Certifying Person, the Depositor (if the Certifying
Person is an individual), and the Depositor's partner, representative,
Affiliate, member, manager, director, officer, employee or agent (collectively
with the Certifying Person, "Certification Parties") can rely. The Trustee's
certification with respect to items 1 through 3 of Exhibit P hereto shall relate
to distribution information, and each Master Servicer's certification with
respect to items 4 and 5 of Exhibit P hereto shall relate to servicing
information with respect to the Mortgage Loans serviced by it hereunder.
Notwithstanding the foregoing, nothing in this paragraph shall require any
Performing Party to (i) certify or verify the accurateness or completeness of
any information provided to such Performing Party by third parties, (ii) to
certify information other than to such Performing Party's knowledge and in
accordance with such Performing Party's responsibilities hereunder or under any
other applicable servicing agreement or (iii) with respect to completeness of
information and reports, to certify anything other than that all fields of
information called for in written reports prepared by such Performing Party have
been completed except as they have been left blank on their face. In the event
any Performing Party is terminated or resigns pursuant to the terms of this
Agreement, such Performing Party shall provide a Performance Certification to
the Depositor pursuant to this Section 8.14(c) with respect to the period of
time such Performing Party was subject to this Agreement.

            (d) If as of the beginning of any fiscal year for the Trust (other
than fiscal year 2003), the Public Certificates are held (directly or, in the
case of Public Certificates held in book-entry form, through the Depository) by
less than 300 Holders and/or Depository Participants having accounts with the
Depository, the Trustee shall, in accordance with the Exchange Act and the rules
and regulations promulgated thereunder, timely file a Form 15 with respect to
the Trust notifying the Commission of the suspension of the reporting
requirements under the Exchange Act.

            (e) Nothing contained in this Section 8.14 shall be construed to
require any party to this Agreement (other than the Depositor), or any of such
party's officers, to execute any Form 10-K or any Sarbanes-Oxley Certification.
The failure of any party to this Agreement, or any of such party's officers, to
execute any Form 10-K or any Sarbanes-Oxley Certification shall not be regarded
as a breach by such party of any of its obligations under this Agreement. The
Depositor, each Performing Party and the Trustee hereby agree to negotiate in
good faith with respect to compliance with any further guidance from the
Commission or its staff relating to the execution of any Form 10-K and any
Sarbanes-Oxley Certification. In the event such parties agree on such matters,
this Agreement shall be amended to reflect such agreement pursuant to Section
11.01.

            (f) Each Performing Party shall indemnify and hold harmless each
Certification Party from and against any losses, damages, penalties, fines,
forfeitures, reasonable and necessary legal fees and related costs, judgments
and other costs and expenses incurred by such Certification Party arising out of
(i) an actual breach by the applicable Performing Party of its obligations under
this Section 8.14, (ii) negligence, bad faith or willful misconduct on the part
of such Performing Party in the performance of such obligations or (iii) any
inaccuracy made in the Performance Certification resulting from such Performing
Party's negligence, bad faith or willful misconduct. A Performing Party shall
have no obligation to indemnify any Certification Party for an inaccuracy in the
Performance Certification of any other Performing Party. If the indemnification
provided for in this Section 8.14 is unavailable or insufficient to hold
harmless a Certification Party (on grounds of public policy or otherwise), then
each Performing Party shall contribute to the amount paid or payable by such
Certification Party as a result of the losses, claims, damages or liabilities of
such Certification Party in such proportion as is appropriate to reflect the
relative fault of such Certification Party on the one hand and each Performing
Party on the other. The obligations of the Performing Parties in this subsection
(f) to contribute are several in the proportions described in the preceding
sentence and not joint.

            Promptly after receipt by an indemnified party of notice of the
commencement of any action, such indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party hereunder, notify in
writing the indemnifying party of the commencement thereof; but the omission to
so notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party under this Agreement except to the extent
that such omission to notify materially prejudices the indemnifying party. In
case any such action is brought against any indemnified party, after the
indemnifying party has been notified of the commencement of such action, such
indemnifying party shall be entitled to participate therein (at its own expense)
and, to the extent that it may wish, shall be entitled to assume the defense
thereof (jointly with any other indemnifying party similarly notified) with
counsel reasonably satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and after notice from the indemnifying party to such indemnified party
of its election to so assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party for any expenses subsequently incurred
in connection with the defense thereof other than reasonable costs of
investigation. In any such proceeding, any indemnified party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the indemnifying party
and the indemnified party shall have agreed to the retention of such counsel,
(ii) the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them or (iii) the indemnifying party fails
within a reasonable period of time to designate counsel that is reasonably
satisfactory to the indemnified party. In no event shall the indemnifying
parties be liable for fees and expenses of more than one counsel (in addition to
any local counsel) in any one jurisdiction separate from their own counsel for
all indemnified parties in connection with any one action or separate but
similar or related actions in the same jurisdiction arising out of the same
general allegations or circumstances. An indemnifying party shall not be liable
for any settlement of any proceeding effected without its written consent.
However, if settled with such consent, the indemnifying party shall indemnify
the indemnified party from and against any loss or liability by reason of such
settlement to the extent that the indemnifying party is otherwise required to do
so under this Agreement. If an indemnifying party assumes the defense of any
proceeding, it shall be entitled to settle such proceeding with the consent of
the indemnified party (which consent shall not be unreasonably withheld) or, if
such settlement (i) provides for an unconditional release of the indemnified
party in connection with all matters relating to the proceeding that have been
asserted against the indemnified party in such proceeding by the other parties
to such settlement and (ii) does not require an admission of fault by the
indemnified party, without the consent of the indemnified party.

            (g) Unless the other parties hereto receive written notice from the
Trustee to the contrary, the Trustee hereby certifies that it intends to file
any Annual Report on Form 10-K with respect to the Trust for any particular
fiscal year on the last Business Day that is not more than 90 days following the
end of such fiscal year. Unless an alternative time period is provided for in
this Agreement, the respective parties hereto shall deliver to the Trustee, at
least 15 Business Days prior to the date on which the Trustee intends to file
any Annual Report on Form 10-K as contemplated by Section 8.14, any items
required to be delivered by such party that are to be an Exhibit to such Annual
Report on Form 10-K. The Trustee hereby notifies the Master Servicers and the
Special Servicers that an Annual Report on Form 10-K shall be required to be
filed with respect to the Trust for 2003.


                                   ARTICLE IX

                                   TERMINATION

            Section 9.01 Termination Upon Repurchase or Liquidation of All
Mortgage Loans

            (a) Subject to Section 9.02, the Trust and the respective
obligations and responsibilities under this Agreement of the parties hereto
(other than the obligations of the Trustee to provide for and make payments to
Certificateholders as hereafter set forth) shall terminate upon payment (or
provision for payment) to the Certificateholders (or any B Loan Holder, if
applicable) of all amounts held by or on behalf of the Trustee and required
hereunder to be so paid on the Distribution Date following the earlier to occur
of: (i) the purchase by a Master Servicer, the Co-op Special Servicer, the
General Special Servicer or any single Controlling Class Certificateholder or
group of Controlling Class Certificateholders of all Mortgage Loans and each REO
Property remaining in the Trust Fund at a price (the "Termination Price") equal
to (A) the aggregate Purchase Price of all the Mortgage Loans remaining in the
Trust Fund (exclusive of any REO Mortgage Loan(s)), plus (B) the appraised value
of each REO Property, if any, included in the Trust Fund, such appraisal to be
conducted by a Qualified Appraiser selected by the applicable Special Servicer
and approved by the Trustee and the applicable Master Servicer, minus (C) if the
purchaser is the applicable Master Servicer or the applicable Special Servicer,
the aggregate amount of unreimbursed Advances made by such Person, together with
any unpaid Advance Interest in respect of such unreimbursed Advances and any
unpaid servicing compensation payable to such Person (which items shall be
deemed to have been paid or reimbursed to such Master Servicer or such Special
Servicer, as the case may be, in connection with such purchase); (ii) if the
aggregate Class Principal Balance of the Class A-1, Class A-2, Class A-3, Class
A-4, Class A-5, Class B, Class C, Class D, and Class E Certificates have been
reduced to zero, the acquisition of all of the Mortgage Loans and REO Properties
remaining in the Trust Fund by the Sole Certificateholder(s) in exchange for all
the remaining Certificates; and (iii) the final payment or other liquidation (or
any advance with respect thereto) of the last Mortgage Loan or REO Property
remaining in the Trust Fund; provided, however, that in no event shall the Trust
continue beyond the expiration of 21 years from the death of the last survivor
of the descendants of Joseph P. Kennedy, the late ambassador of the United
States to the Court of St. James, living on the date hereof.

            (b) Any single Controlling Class Certificateholder or group of
Controlling Class Certificateholders, the NCBFSB Master Servicer, the Co-op
Special Servicer, the General Master Servicer or the General Special Servicer,
in that order of preference, may at its option elect to purchase all the
Mortgage Loans and each REO Property remaining in the Trust Fund as contemplated
by clause (i) of Section 9.01(a) by giving written notice to the other parties
hereto (and, in the case of an election by a Master Servicer or Special
Servicer, to the Holders of the Controlling Class) no later than 60 days prior
to the anticipated date of purchase; provided, however, that the aggregate
Stated Principal Balance of the Mortgage Pool at the time of such election is
less than 1.0% of the Initial Pool Balance; and provided, further, that within
30 days after written notice of such election is so given, no Person with a
higher right of priority to make such an election does so; and provided,
further, that if more than one Controlling Class Certificateholder or group of
Controlling Class Certificateholders desire to purchase all of the Mortgage
Loans and any REO Properties, preference shall be given to the Controlling Class
Certificateholder or group of Controlling Class Certificateholders with the
largest Percentage Interest in the Controlling Class; and provided, further,
that if any single Controlling Class Certificateholder or group of Controlling
Class Certificateholders, the Co-op Special Servicer, the General Master
Servicer or the General Special Servicer makes such an election, then the NCBFSB
Master Servicer will have the option, by giving written notice to the other
parties hereto and to the Holders of the Controlling Class no later than 30 days
prior to the anticipated date of purchase, to purchase all of the NCBFSB
Serviced Mortgage Loans and each related REO Property remaining in the Trust
Fund, and the other party will then have the option to purchase only the
non-NCBFSB Serviced Mortgage Loans and each related REO Property remaining in
the Trust Fund. If the Trust is to be terminated in connection with the purchase
of all the Mortgage Loans and each REO Property remaining in the Trust Fund by a
Master Servicer, a Special Servicer and/or any Controlling Class
Certificateholder(s), such Person(s) shall: (i) deposit, or deliver to each of
the Master Servicers for deposit in the Master Servicers' respective Collection
Accounts (after the Determination Date, and prior to the Master Servicer
Remittance Date, relating to the anticipated Final Distribution Date) an amount
in immediately available funds equal to the Termination Price (the portion
thereof allocable to all the Trust Assets (other than the NCBFSB Trust Assets if
the NCBFSB Master Servicer elects to purchase the remaining NCBFSB Trust Assets
in accordance with the preceding sentence) to be deposited in the General Master
Servicer's Collection Account (and the portion thereof allocable to the NCBFSB
Trust Assets if the NCBFSB Master Servicer elects to purchase the remaining
NCBFSB Trust Assets in accordance with the preceding sentence to be deposited in
the NCBFSB Master Servicer's Collection Account); and (ii) shall reimburse all
of the parties hereto (other than itself, if applicable) for all reasonable
out-of-pocket costs and expenses incurred by such parties in connection with
such purchase. On the Master Servicer Remittance Date for the Final Distribution
Date, the applicable Master Servicer shall transfer to the Lower-Tier
Distribution Account all amounts required to be transferred by it to such
account on such Master Servicer Remittance Date from such Master Servicer's
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 the deposit of the
Termination Price has been made to the Collection Account(s) and the
reimbursement contemplated by the second preceding sentence has been made to the
parties hereto, the Trustee shall release or cause to be released to the
purchasing party (or its designee) the Mortgage Files for the remaining Mortgage
Loans and shall execute all assignments, endorsements and other instruments
furnished to it by the purchasing party as shall be necessary to effectuate
transfer of the Mortgage Loans and REO Properties to the purchasing party (or
its designee).

            Following the date on which the aggregate Certificate Principal
Balance of the Registered Certificates is reduced to zero, the Sole
Certificateholder(s) shall have the right to exchange all of the Certificates
for all of the Mortgage Loans and each REO Property remaining in the Trust Fund
as contemplated by clause (ii) of Section 9.01(a) by giving written notice to
all the parties hereto no later than 60 days prior to the anticipated date of
exchange. In the event that the Sole Certificateholder(s) elect(s) to exchange
all of the Certificates for all of the Mortgage Loans and each REO Property
remaining in the Trust Fund in accordance with the preceding sentence, such Sole
Certificateholder(s), not later than the Business Day prior to the Distribution
Date on which the final distribution on the Certificates is to occur, shall
deposit in each Collection Account an amount in immediately available funds
equal to all amounts then due and owing to the Depositor, the Master Servicers,
the Special Servicers, the Trustee and/or any Fiscal Agent hereunder that may be
withdrawn from such Collection Account, pursuant to Section 3.05(a), or that may
be withdrawn from the 622 Third Avenue Loan REMIC Distribution Account or the
Lower-Tier Distribution Account, pursuant to Section 3.05(b), but only to the
extent that such amounts are not already on deposit in such Collection Account.
In addition, the Master Servicers shall transfer to the Trustee for deposit into
the 622 Third Avenue Loan REMIC Distribution Account or the Lower-Tier
Distribution Account all amounts required to be transferred by it to such
account on such Master Servicer Remittance Date from such Master Servicer's
Collection Account pursuant to the first paragraph of Section 3.04(b). Upon
confirmation that such final deposits have been made and following the surrender
of all the Certificates on the Final Distribution Date, the Trustee shall
release or cause to be released to the Sole Certificateholder(s) or any designee
thereof, the Mortgage Files for the remaining Mortgage Loans and shall execute
all assignments, endorsements and other instruments furnished to it by the Sole
Certificateholder(s) as shall be necessary to effectuate transfer of the
Mortgage Loans and REO Properties remaining in the Trust Fund. The exchange of
all of the Certificates by the Sole Certificateholder for all of the Mortgage
Loans and REO Property shall be treated for federal income tax purposes as a
purchase of the Trust Fund for cash and a distribution to the 622 Third Avenue
Loan REMIC Regular Interests, the Uncertificated Lower-Tier Interests and the
Certificates in accordance with Section 4.01(a), Section 4.01(c), Section
4.01(d) and Section 4.01(k) in complete liquidation of the 622 Third Avenue Loan
REMIC, the Lower-Tier REMIC and the Upper-Tier REMIC.

            (c) Notice of any termination shall be given promptly by the Trustee
by letter to Certificateholders and each B Loan Holder and Washington Center
Junior Holder mailed (x) if such notice is given in connection with the purchase
of all the Mortgage Loans and each REO Property remaining in the Trust Fund by
the Master Servicers, the Special Servicers or any Controlling Class
Certificateholder(s), 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 and (y) otherwise during the month of such final distribution on or
before the Master Servicer Remittance Date in such month, in any event
specifying (i) the Distribution Date upon which the Trust Fund will terminate
and final payment on the Certificates will be made, (ii) the amount of any such
final payment in respect of each Class of Certificates 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
office or agency of the Trustee therein designated. The Trustee shall give such
notice to the other parties hereto at the time such notice is given to
Certificateholders.

            (d) After transferring (i) distributions in respect of the 622 Third
Avenue Loan REMIC Regular Interests pursuant to Sections 4.01(k) and 4.01(d)
from the 622 Third Avenue Loan REMIC Distribution Account to the Lower-Tier
Distribution Account and (ii) the Lower-Tier Distribution Amount and the amount
of any Prepayment Premiums and Yield Maintenance Charges distributable pursuant
to Section 4.01(c) and 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
Trustee 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 622 Third Avenue Loan REMIC
Distribution Account to the Lower-Tier Distribution Account in respect of the
622 Third Avenue Loan REMIC Regular Interests and 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(c), 4.01(d), 4.01(k) and
4.01(e)(ii) and shall be distributed in termination and liquidation of the 622
Third Avenue Loan REMIC Regular Interests, the Uncertificated Lower-Tier
Interests and the Class LR Certificates. 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(g).

            Section 9.02 Additional Termination Requirements

            If a Master Servicer, a Special Servicer or a Controlling Class
Certificateholder purchases, or the Sole Certificateholder(s) exchange all of
the Certificates for, all the Mortgage Loans and each REO Property remaining in
the Trust Fund as provided in Section 9.01, the Trust and each Trust REMIC shall
be terminated in accordance with the following additional requirements, which
meet the definition of a "qualified liquidation" of the 622 Third Avenue Loan
REMIC, the Lower-Tier REMIC and the Upper-Tier REMIC, within the meaning of
Section 860F(a)(4) of the Code:

            (i) the Trustee shall specify the first day in the 90-day
      liquidation period in a statement attached to each of the Trust REMICs'
      final Tax Returns pursuant to Treasury Regulations Section 1.860F-1;

            (ii) within 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 or otherwise transfer all of the assets of the 622 Third Avenue
      Loan REMIC and the Lower-Tier REMIC (other than the 622 Third Avenue Loan
      REMIC Regular Interests, which shall be liquidated) to such Special
      Servicer, the Holders of the Controlling Class or such Master Servicer, as
      the case may be, for cash; and

            (iii) immediately following the making of the final payment on the
      622 Third Avenue Loan REMIC Regular Interests, the Uncertificated
      Lower-Tier Interests and the Certificates, the Trustee shall distribute or
      credit, or cause to be distributed or credited, to the Class LR
      Certificates (in the case of the 622 Third Avenue Loan REMIC Residual
      Interest and the residual interest in 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 622 Third Avenue Loan REMIC, the Lower-Tier REMIC and the Upper-Tier
      REMIC shall terminate at that time.

            In addition, the 622 Third Avenue Loan REMIC shall be liquidated
upon a repurchase of the 622 Third Avenue Loan from the Trust Fund as a result
of a repurchase upon a breach of a representation or warranty with respect to
the 622 Third Avenue Loan set forth in the Mortgage Loan Purchase Agreement, and
the date of such repurchase shall be specified in the 622 Third Avenue Loan
REMIC's final federal income tax return as the date of adoption of a plan of
complete liquidation of such REMIC.

            References to "REO Property" and "REO Properties" in Section 9.01
and Section 9.02 shall mean, in the context of any Great Lakes Crossing REO
Property, solely the Trust's interest in the Great Lakes Crossing REO Property.

                                   ARTICLE X

                            ADDITIONAL TAX PROVISIONS

            Section 10.01 REMIC Administration

            (a) The Trustee shall make or cause to be made elections to treat
each of the Lower-Tier REMIC, the Upper-Tier REMIC and the 622 Third Avenue Loan
REMIC as a REMIC under the Code and, if necessary, under applicable State Tax
Laws. Each such election will be made on IRS 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
Trustee 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 Master Servicers, the Special Servicers and the
Trustee shall not permit the creation of any "interests" (within the meaning of
Section 860G of the Code) in any Trust REMIC other than the foregoing interests.

            (b) The Closing Date is hereby designated as the Startup Day for the
Lower-Tier REMIC, the Upper-Tier REMIC and the 622 Third Avenue Loan REMIC
within the meaning of Section 860G(a)(9) of the Code.

            (c) [Reserved.]

            (d) 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 each of the Lower-Tier
REMIC and the 622 Third Avenue Loan REMIC. The Holder of the largest Percentage
Interest 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 Trustee is hereby designated as the agent of the Tax
Matters Person 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.

            (e) The Trustee shall prepare or cause to be prepared all of the Tax
Returns that are required with respect to each Trust REMIC created hereunder and
shall sign and file or cause to be filed such Tax Returns in a timely manner.
The expenses of preparing such returns shall be borne by the Trustee without any
right of reimbursement therefor.

            (f) The Trustee 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 a
Disqualified Organization or (y) otherwise required to be provided by Treasury
Regulations Section 1.860E-2 (and in the time and manner required to be provided
to such person under such Regulations), (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 IRS the name, title, address and telephone number of the person who will
serve as the representative of each of the Trust REMICs.

            (g) The Trustee shall take such actions and shall cause the Trust
Fund to take such actions as are reasonably within the Trustee's control and the
scope of its duties more specifically set forth herein as shall be necessary to
maintain the status of each Trust REMIC as a REMIC under the REMIC Provisions
(and the Master Servicers and Special Servicers shall assist the Trustee, to the
extent reasonably requested by the Trustee to do so). None of the Master
Servicers, the Special Servicers or the Trustee shall knowingly or intentionally
take any action, cause the Trust Fund 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 any Trust
REMIC to fail to qualify as a REMIC or (ii) result in the imposition of a tax
under the REMIC Provisions upon any Trust REMIC (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 any Trust REMIC, cause any Trust REMIC to fail to qualify as a REMIC
or, unless such party (which is acceptable to the Trustee) determines that the
monetary expense to any Trust REMIC is not material and in its sole discretion
to indemnify (to the extent reasonably acceptable to the Trustee) 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 taking 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 Trustee shall not take any
action (whether or not authorized hereunder) as to which a Master 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 Trustee or its designee, in writing, with respect to whether
such action could cause an Adverse REMIC Event to occur with respect to any
Trust REMIC, and such party shall not take any such action, or cause any Trust
REMIC to take any such action, as to which the Trustee has advised it in writing
that an Adverse REMIC Event could occur. The Trustee 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 Trustee 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 each Trust REMIC 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. With respect to the 622 Third Avenue Loan and
the Washington Center Loan, no B Loan Holder or C Loan Holder shall bear the
costs associated with obtaining any Opinion of Counsel relating to maintaining
each Trust REMIC as a REMIC or be required to bear any expenses or costs
associated therewith.

            (h) In the event that any tax is imposed on "prohibited
transactions" of any Trust REMIC as defined in Section 860F(a)(2) of the Code,
on "net income from foreclosure property" of any Trust 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 Master Servicer, if such tax arises out of or results from a breach, which
breach constitutes negligence or willful misconduct of such Master Servicer, by
such Master Servicer of any of its obligations under this Agreement and such
breach is not caused by the breach of another party, (ii) to the Trustee, if
such tax arises out of or results from a breach, which breach constitutes
negligence or willful misconduct of the Trustee, by the Trustee of any of its
obligations under this Agreement and such breach is not caused by the breach of
another party, (iii) to a Special Servicer, if such tax arises out of or results
from a breach, which breach constitutes negligence or willful misconduct of such
Special Servicer, by such Special Servicer of any of its obligations under this
Agreement and such breach is not caused by the breach of another party and (iv)
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 a
Net Aggregate Prepayment Interest Shortfall.

            (i) The Trustee shall, for federal income tax purposes, maintain
books and records with respect to each of the Trust REMICs on a calendar year
and on an accrual basis.

            (j) Following the Startup Day, none of the Master Servicers, the
Special Servicers or the Trustee shall accept any contributions of assets to any
Trust REMIC unless the Master Servicers, the Special Servicers 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
any Trust REMIC will not cause any Trust REMIC to fail to qualify as a REMIC at
any time that any Certificates are outstanding or subject any Trust REMIC
created hereunder to any tax under the REMIC Provisions or other applicable
provisions of federal, state and local law or ordinances.

            (k) None of the Master Servicers, the Special Servicers or the
Trustee shall enter into any arrangement by which any Trust REMIC will receive a
fee or other compensation for services nor, to the extent reasonably within
their control, permit any Trust REMIC to receive any income from assets other
than "qualified mortgages" as defined in Section 860G(a)(3) of the Code or
"permitted investments" as defined in Section 860G(a)(5) of the Code.

            (l) For the purposes of Treasury Regulations Section
1.860G-1(a)(4)(iii), the "latest possible maturity date" of the 622 Third Avenue
Loan REMIC Regular Interests, the Uncertificated Lower-Tier Interests and the
Regular Certificates is the Rated Final Distribution Date.

            (m) Within 30 days after the Closing Date, the Trustee 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.

            (n) None of the Trustee, the Master Servicers or the Special
Servicers shall sell or dispose of or substitute for any of the Mortgage Loans
(except in connection with (i) the default, reasonably foreseeable default or
foreclosure of a Mortgage 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 the Trust Fund, (iii) the termination of the Trust Fund pursuant
to Article X of this Agreement or (iv) a purchase of Mortgage Loans pursuant to
Article II, Section 3.18 or Section 9.01 of this Agreement) nor acquire any
assets for the Trust Fund or any Trust REMIC, nor sell or dispose of any
investments in the Collection Account for gain, nor accept any contributions to
any Trust REMIC after the Closing Date, unless it has received an Opinion of
Counsel (at the expense of the Person seeking such sale or acquisition) that
such sale or disposition will not affect adversely the status of any Trust REMIC
as a REMIC or cause any Trust REMIC to be subject to a tax on "prohibited
transactions" or "contributions" pursuant to the REMIC Provisions.

            (o) The Depositor shall provide or cause to be provided to the
Trustee, within ten (10) days after the Closing Date, and thereafter on an
ongoing basis, all information or data requested by the Trustee that the Trustee
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, issue premium and projected cash flow of the
Certificates. In addition, the Master Servicers, the Special Servicers and the
Depositor shall provide on a timely basis to the Trustee or its designee such
information with respect to the Trust Fund as is in its possession and
reasonably requested by the Trustee to enable it to perform its obligations
under this Section. The Trustee shall be entitled to rely conclusively upon all
such information so provided to it without recalculation or other investigation.

            (p) 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 10.01 as may be agreed upon by the Trustee and the
Depositor; provided, however, that 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 "unanticipated expenses incurred by the REMIC" within the meaning
of the REMIC Provisions, 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 Trustee for the benefit or protection of the Certificateholders.

            Section 10.02 Grantor Trust Reporting

            The parties intend that the portions of the Trust Fund consisting of
Post-ARD Additional Interest and the Post-ARD Additional Interest Distribution
Account shall constitute, and that the affairs of the Trust Fund (exclusive of
the Upper-Tier REMIC, the Lower-Tier REMIC and the 622 Third Avenue Loan REMIC)
shall be conducted so as to qualify such portion as, a "grantor trust" under the
Code, and the provisions hereof shall be interpreted consistently with this
intention. In furtherance of such intention, the Trustee shall furnish or cause
to be furnished to Class V Certificateholders information returns with respect
to income relating to their share of Post-ARD Additional Interest and such other
information as may be applicable, and shall file, or cause to be filed with the
IRS, Form 1041 or such other form as may be applicable, together with copies of
such information furnished to Class V Certificateholders, at the time or times
and in the manner required by the Code.

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

            Section 11.01 Amendment

            (a) This Agreement may be amended from time to time by the mutual
agreement of the parties hereto, without the consent of any of the
Certificateholders or any B Loan Holder, (i) to cure any ambiguity, (ii) to

restriction imposed on the Certificates pursuant to Section 5.02(b) or Section
5.02(c) (if applicable law is amended or clarified such that any such
restriction may be relaxed or eliminated), (v) as evidenced by an Opinion of
Counsel delivered to the Trustee, either (X) to comply with any requirements
imposed by the Code or any successor or amendatory statute or any temporary or
final regulation, revenue ruling, revenue procedure or other written official
announcement or interpretation relating to federal income tax laws or any such
proposed action which, if made effective, would apply retroactively to any Trust
REMIC or the Grantor Trust at least from the effective date of such amendment,
or (Y) to avoid the occurrence of a prohibited transaction or to reduce the
incidence of any tax that would arise from any actions taken with respect to the
operation of any Trust REMIC or the Grantor Trust, (vi) subject to Section
5.02(d)(iv), to modify, add to or eliminate any of the provisions of Section

significantly change the activities of the Trust; and provided, further, that
any such amendment for the specific purposes described in clause (iii) or (vii)
above shall not adversely affect in any material respect the interests of any
Certificateholder or any third-party beneficiary to this Agreement or any
provision hereof, as evidenced by the Trustee's receipt of an Opinion of Counsel
to that effect (or, alternatively, in the case of a Class of Rated Certificates,
written confirmation from each applicable Rating Agency to the effect that such
amendment shall not result in an Adverse Rating Event with respect to any Class
of Rated Certificates); and provided, further, that with respect to any such
amendment for the specific purposes described in clause (iii) above, the Trustee
shall receive written confirmation from each applicable Rating Agency to the

            (b) This Agreement may also be amended from time to time by the
mutual agreement of the parties hereto, with the consent of the Holders of
Certificates entitled to not less than 51% of the Voting Rights allocated to all
of the Classes that are materially affected by the amendment, 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

Certificate, or which are required to be distributed to any B Loan Holder or
Washington Center Junior Holder, without the consent of such B Loan Holder or
Washington Center Junior Holder, (ii) adversely affect in any material respect
the interests of the Holders of any Class of Certificates or any B Loan Holder
or Washington Center Junior Holder in a manner other than as described in clause

consents pursuant to this Section 11.01, Certificates registered in the name of
the Depositor or any Affiliate of the Depositor shall be entitled to the same
Voting Rights with respect to the matters described above as they would if

any amendment to this Agreement unless it shall first have obtained or been
furnished with an Opinion of Counsel to the effect that neither such amendment
nor the exercise of any power granted to any party hereto in accordance with
such amendment will result in an Adverse REMIC Event with respect to any Trust
REMIC or an Adverse Grantor Trust Event with respect to the Grantor Trust.

            (d) Promptly after the execution and delivery of any amendment by
all parties thereto, the Trustee shall send a copy thereof to each
Certificateholder, each B Loan Holder, each Washington Center Junior Holder and
to each Rating Agency.

            (e) It shall not be necessary for the consent of Certificateholders
under this Section 11.01 to approve the particular form of any proposed
amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization, execution and delivery 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 11.01 that affects its rights, duties and
immunities under this Agreement or otherwise.

interests of Certificateholders, the cost of any Opinion of Counsel required in
connection therewith pursuant to Section 11.01(a) or (c) shall be payable out of
the Distribution Account.

            Section 11.02 Recordation of Agreement; Counterparts

            (a) To the extent permitted by applicable law, this Agreement is

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 Trustee at the expense of the Trust (payable out of the

applicable, determines in its reasonable good faith judgment, that such
recordation materially and beneficially affects the interests of the
Certificateholders and so informs the Trustee in writing and (ii) the
Controlling Class Representative consents.

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

            Section 11.03 Limitation on Rights of Certificateholders, B Loan
Holders and Washington Center Junior Holders

            (a) The death or incapacity of any Certificateholder, any B Loan
Holder or any Washington Center Junior Holder shall not operate to terminate
this Agreement or the Trust Fund, nor entitle such Certificateholder's, such B
Loan Holder's or such Washington Center Junior Holder'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, B Loan Holder or Washington Center Junior
Holder 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, the B Loan Holders and/or the Washington Center Junior
Holders from time to time as partners or members of an association; nor shall
any Certificateholder, any B Loan Holder or any Washington Center Junior Holder
be under any liability to any third party by reason of any action taken by the
parties to this Agreement pursuant to any provision hereof.

            (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement or any Mortgage
Loan, unless, with respect to any suit, action or proceeding upon or under or
with respect to this Agreement, such Holder previously shall have given to the
Trustee a written notice of default hereunder, and of the continuance thereof,
as hereinbefore provided, and unless also (except in the case of a default by
the Trustee) the Holders of Certificates entitled to at least 25% of the Voting
Rights shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and shall have
offered to the Trustee such reasonable indemnity as it may require against the
costs, expenses and liabilities to be incurred therein or thereby, and the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding. It is understood and intended, and expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more Holders of Certificates shall have any right in any manner
whatsoever by virtue of any provision of this Agreement to affect, disturb or
prejudice the rights of any other Holders of 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 11.03, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

            Section 11.04 Governing Law

                                  ARTICLE XII

                SERVICING OF THE GREAT LAKES CROSSING LOAN GROUP
          FOLLOWING A GREAT LAKES CROSSING CHANGE OF SERVICING CONTROL
                                     EVENT

            Section 12.01 General

            (a) The terms of this Article XII shall apply only if and when a
Great Lakes Crossing Change of Servicing Control Event shall occur, and shall
remain in effect only for so long as the Great Lakes Crossing Mortgage Loan or
any interest in any Great Lakes Crossing REO Property remains an asset of the
Trust.

            (b) If and when a Great Lakes Crossing Change of Servicing Control
Event shall occur, each of the Master Servicer and the Special Servicer shall
diligently service and administer the Great Lakes Crossing Total Loan (and, with
respect to the Special Servicer, any Great Lakes Crossing REO Property) as and
when it is required to do so, pursuant to this Article XII on behalf of the
Trustee and in the best interests of and for the benefit of the
Certificateholders and the holders of the Great Lakes Crossing Companion Loan,
taken as a collective whole (as determined by the Master Servicer or the Special
Servicer, as the case may be, in its reasonable judgment), in accordance with
applicable law, the terms of the Great Lakes Crossing Total Loan, the terms of
the Great Lakes Crossing Intercreditor Agreement and, to the extent consistent
with the foregoing, the Series 2003-CK2 Servicing Standard. Without limiting the
foregoing, subject to Section 12.14 hereunder, the Special Servicer shall be
obligated to service and administer the Great Lakes Crossing Total Loan while a
Series 2003-CK2 Servicing Transfer Event has occurred and is continuing with
respect thereto and to service and administer any Great Lakes Crossing REO
Property; provided that the Master Servicer shall continue to make all
calculations, and prepare, and deliver to the Trustee, all reports required to
be prepared by the Master Servicer hereunder with respect to the Great Lakes
Crossing Mortgage Loan as if no Series 2003-CK2 Servicing Transfer Event had
occurred with respect thereto or as if the Great Lakes Crossing Mortgaged
Property had not become an REO Property, as the case may be, and to render such
incidental services with respect to the Great Lakes Crossing Total Loan while
any Series 2003-CK2 Servicing Transfer Event exists with respect thereto or
while the Great Lakes Crossing Mortgaged Property constitutes an REO Property,
as the case may be. Also without limiting the foregoing, the Master Servicer
shall be obligated to service and administer the Great Lakes Crossing Total Loan
prior to the occurrence of the Series 2003-CK2 Servicing Transfer Event and
after all Series 2003-CK2 Transfer Events have ceased to exist, in either case
with respect to the Great Lakes Crossing Total Loan. In connection with the
foregoing, the Master Servicer and the Special Servicer shall have all right,
power and authority granted to, and all duties and obligations imposed upon, the
Series 2003-CK2 Master Servicer and the Series 2003-CK2 Special Servicer,
respectively, pursuant to Section 3.01(b) and Section 3.01(d) of the Series
2003-CK2 PSA, except that all references in the Series 2003-CK2 PSA to
"Certificateholders" and "Trustee" shall be deemed to mean the
"Certificateholders" and "Trustee", respectively, hereunder.

            (c) Whenever the Master Servicer or the Special Servicer is required
to act under this Article XII in accordance with the Series 2003-CK2 Servicing
Standard, such standard shall be applied with the following changes:

            (i) the reference to "Certificateholders" in clause (ii) of the
      first paragraph of Section 3.01(a) of the Series 2003-CK2 PSA shall be
      deemed a reference to the holder of the Great Lakes Crossing Companion
      Loan; and

            (ii) the reference to "Certificate" in subclause (iii)(b) of the
      first paragraph of Section 3.01(a) of the Series 2003-CK2 PSA shall be
      deemed a reference to any ownership interest in the Great Lakes Crossing
      Mortgage Loan or in either of the Great Lakes Crossing Companion Loan.

            In addition, even when the Master Servicer or the Special Servicer
is required to act under this Article XII with respect to the Great Lakes
Crossing Total Loan as if it constituted Serviced Mortgage Loans or any Great
Lakes Crossing REO Property as if it constituted an Administered REO Property,
the Series 2003-CK2 Servicing Standard (with the foregoing changes) will apply
rather than the Servicing Standard hereunder.

            (d) The Controlling Class Representative shall, subject to Section
3.24(b) hereunder, be entitled to exercise all rights and powers that would
otherwise be exercisable by the Series 2003-CK2 Directing Certificateholder in
connection with the matters contemplated by this Article XII. To the extent that
the Master Servicer or the Special Servicer would have any obligation to notify,
seek direction or approval from, obtain the consent of or otherwise interact
with the Series 2003-CK2 Directing Certificateholder in accordance with this
Article XII, it shall, subject to Section 3.24(b) hereunder, instead notify,
seek direction or approval from, obtain the consent of or otherwise interact
with the Controlling Class Representative. The Controlling Class Representative
shall be entitled to receive from each of the Master Servicer and the Special
Servicer all reports, statements, documents, certifications, information and
communications with respect to the Great Lakes Crossing Total Loan that would
otherwise have been delivered to the Series 2003-CK2 Directing Certificateholder
by the Series 2003-CK2 Master Servicer and the Series 2003-CK2 Special Servicer,
respectively, under the Series 2003-CK2 PSA.

            (e) To the extent that the Master Servicer or the Special Servicer
would have any obligation to notify, seek a ratings confirmation from or
otherwise interact with the Series 2003-CK2 Rating Agencies in accordance with
this Article XII, it shall instead notify, seek a ratings confirmation from or
otherwise interact with the Rating Agencies, and any such ratings confirmation
shall relate to the ratings on the Certificates issued hereunder. Fitch and
Moody's shall continue to be entitled to receive from each of the Master
Servicer, the Special Servicer and the Trustee all reports, statements,
documents, certifications, information and communications with respect to the
Great Lakes Crossing Total Loan that it would otherwise have been entitled to
receive from the Series 2003-CK2 Master Servicer, the Series 2003-CK2 Special
Servicer and the Series 2003-CK2 Trustee, respectively, under the Series
2003-CK2 PSA.

            (f) Any Holder of a Class L, Class M, Class N or Class P Certificate
shall be entitled to exercise all rights and powers that would otherwise be
exercisable by a Series 2003-CK2 Requesting Subordinate Certificateholder in
connection with the matters contemplated by this Article XII. To the extent that
the Master Servicer or the Special Servicer would have any obligation to notify
or otherwise interact with the Series 2003-CK2 Requesting Subordinate
Certificateholders in accordance with this Article XII, it shall instead notify
or otherwise interact with the Holders of the Class L, Class M, Class N or Class

the Special Servicer all reports, statements, documents, certifications,
information and communications with respect to the Great Lakes Crossing Total
Loan that would otherwise have been delivered to the Series 2003-CK2 Requesting
Subordinate Certificateholders by the Series 2003-CK2 Master Servicer and the
Series 2003-CK2 Special Servicer, respectively, under the Series 2003-CK2 PSA.

            (a) The Master Servicer and the Special Servicer shall perform all

            (c) Each of the Master Servicer, the Special Servicer, the Trustee

and subject to the same terms, conditions and limitations, as would be
applicable to entering into Sub-Servicing Agreements with respect to the
Serviced Mortgage Loans under Section 3.22 hereunder.

            Section 12.16 P&I Advances

            The Master Servicer shall have the same advancing obligations with
respect to the Great Lakes Crossing Total Loan as did the Series 2003-CK2 Master
Servicer under Section 4.03 of the Series 2003-CK2 PSA.

            Section 12.17 Limitation on Liability; Certain Indemnities

            Solely insofar as it relates to the matters contemplated by this
Article XII, Section 6.03 of the Series 2003-CK2 PSA is incorporated herein by
reference and made a part hereof; provided that capitalized terms that are used
therein and are defined in this Agreement shall have the respective meanings
assigned thereto in this Agreement; and provided, further, that the term "Great
Lakes Crossing Companion Mortgage Loan," as used therein, shall be deemed to
mean the Great Lakes Crossing Companion Loan. Section 6.03 of this Agreement
shall not be applicable to, and is replaced in its entirety with respect to, the
matters contemplated by this Article XII.

            Section 12.18 Events of Default

            (a) If any Event of Default shall occur hereunder that materially
and adversely affects the rights and interests of the holder of the Great Lakes
Crossing Companion Loan, then such holder shall have the same rights (and be
subject to the same constraints, including the obtaining of any required rating
confirmations) in respect of such Event of Default as did the holder of the
Great Lakes Crossing Mortgage Loan upon the occurrence of a Series 2003-CK2
Event of Default.

            (b) In the event that the Master Servicer or the Special Servicer
may be terminated under this Section 12.19, but is not otherwise terminated
under Article VII hereof, then such party shall be replaced solely as to its
duties and obligations, and its right, power and authority, with respect to the
Great Lakes Crossing Total Loan and any Great Lakes Crossing REO Property, and
all references to "Master Servicer" or "Special Servicer" in this Article XII
shall be deemed to refer to its successor under this Article XII. Articles I
through XI hereof shall apply to such successor master servicer or special
servicer, as applicable, but only to the extent that they would if the Great
Lakes Crossing Total Loan and/or any Great Lakes Crossing REO Property were the
only asset being serviced and administered hereunder and there were no Serviced
Mortgage Loans or Administered REO Properties. The Master Servicer or Special
Servicer, as the case may be, that was so replaced with respect to the Great
Lakes Crossing Total Loan and/or any Great Lakes Crossing REO Property shall
continue to have the same duties and obligations, and the same right, power and
authority, with respect to the Serviced Mortgage Loans and/or any Administered
REO Properties that it otherwise would without regard to this Article XII, and
Articles I through XI hereof shall apply to such replaced Master Servicer or
Special Servicer, as the case may be, as if this Article XII did not exist.

            Section 12.19 Amendments to the Series 2003-CK2 PSA

            All references to the Series 2003-CK2 PSA throughout this Article
XII are intended to be references to such agreement as in effect on the Closing
Date, with such amendments and modifications as either (i) have been agreed to
by the Trustee in accordance with Article XI hereof or (ii) do not materially
and adversely affect the interests of the holder of the Great Lakes Crossing
Mortgage Loan.

of the subject Global Certificate, and cause a Definitive Certificate of the
same Class as such Global Certificate, and in a denomination equal to the

authenticated and delivered in accordance with this Agreement to the applicable
Transferee.

            The Global Certificates shall be deposited with the Trustee as
custodian for DTC and registered in the name of Cede & Co. as nominee of DTC.

CSFB Corporation, the Depositor, the Trustee, the General Master Servicer, the
NCBFSB Master Servicer, the General Special Servicer, the Co-op Special

applicable, the Certificate Owner effecting the transfer) that such transfer
will not result in a violation of Section 406 or 407 of ERISA or Section 4975 of
the Code or result in the imposition of an excise tax under Section 4975 of the

Certificate Registrar a certification to the effect that, and such other

transfer at the offices of the Certificate Registrar, duly endorsed by, or
accompanied by a written instrument of transfer in the form satisfactory to the

Interest will be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of this Certificate, but the Trustee or the Certificate Registrar

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

            Subject to certain terms and conditions set forth in the Agreement,
the Trust Fund and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment or
other liquidation (or any advance with respect thereto) of the last Mortgage
Loan or REO Property remaining in the Trust Fund, (ii) the purchase by the
NCBFSB Master Servicer, the Co-op Special Servicer, the General Master Servicer,
the General Special Servicer, or any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, at a price determined as
provided in the Agreement, of all the Mortgage Loans and each REO Property
remaining in the Trust Fund and (iii) the acquisition by the Sole
Certificateholder(s) of all the Mortgage Loans and each REO Property remaining
in the Trust Fund in exchange for all of the Certificates. The Agreement
permits, but does not require, the NCBFSB Master Servicer, the Co-op Special
Servicer, the General Master Servicer, the General Special Servicer, or any
single Controlling Class Certificateholder or group of Controlling Class
Certificateholders to purchase from the Trust Fund all the Mortgage Loans and
each REO Property remaining therein. The exercise of such right may effect early
retirement of the Certificates; however, such right to purchase is subject to
the aggregate Stated Principal Balance of the Mortgage Pool at the time of
purchase being less than 1.0% of the Initial Net Pool Balance.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the General Master Servicer, the NCBFSB Master Servicer, the General

Depositor, the General Master Servicer, the NCBFSB Master Servicer, the General
Special Servicer, the Co-op Special Servicer, the Trustee and any Fiscal Agent
with the consent of the Holders of Certificates entitled to not less than 51% of
the Voting Rights allocated to all of the Classes materially affected by the
amendment. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of any REMIC Pool as a REMIC, without the consent of the Holders of any
of the Certificates.

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

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

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

Special Servicer, the Co-op Special Servicer, the Trustee and any Fiscal Agent
with the consent of the Holders of Certificates entitled to not less than 51% of
the Voting Rights allocated to all of the Classes materially affected by the

conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of any REMIC Pool as a REMIC, without the consent of the Holders of any
of the Certificates.

            Unless the certificate of authentication hereon has been executed by

distributions hereunder.

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

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

            Pursuant to the terms of the Agreement, beginning on the First

"Distribution Date") each month that is the fourth Business Day following the
Determination Date in such month, to the Person in whose name this Certificate

the Certificate Principal Balance hereof is binding on such Holder and all
future Holders of this Certificate and any Certificate issued upon the transfer

set forth, this Certificate is exchangeable for new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage

            No transfer, sale, pledge or other disposition of this Certificate
or any interest herein shall be made unless that transfer, sale, pledge or other
disposition is exempt from the registration and/or qualification requirements of
the Securities Act and any applicable state securities laws, or is otherwise
made in accordance with the Securities Act and such state securities laws. If a
transfer of this Certificate is to be made without registration under the
Securities Act, then (except under limited circumstances specified in the
Agreement) the Certificate Registrar shall refuse to register such transfer

certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1A to the Agreement; or (ii) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1B to the Agreement and a
certificate from such Certificateholder's prospective Transferee substantially
in the form attached either as Exhibit F-2A or as Exhibit F-2B to the Agreement;
or (iii) an Opinion of Counsel satisfactory to the Certificate Registrar to the
effect that such transfer may be made without registration under the Securities
Act (which Opinion of Counsel shall not be an expense of the Trust or of the
Depositor, the General Master Servicer, the NCBFSB Master Servicer, the General
Special Servicer, the Co-op Special Servicer, the Trustee, any Fiscal Agent or
the Certificate Registrar in their respective capacities as such), together with
the written certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based.

            If this Certificate constitutes a Rule 144A Global Certificate and a
transfer of any interest in this Certificate is to be made without registration
under the Securities Act, then (except under limited circumstances specified in
the Agreement) the Certificate Owner desiring to effect such transfer shall be
required to obtain either (i) a certificate from such Certificate Owner's
prospective Transferee substantially in the form attached as Exhibit F-2C to the
Agreement, or (ii) an Opinion of Counsel to the effect that such prospective
Transferee is a Qualified Institutional Buyer and such transfer may be made
without registration under the Securities Act. Except as discussed below, if
this Certificate constitutes a Rule 144A Global Certificate, then interests
herein shall not be transferred to any Person who takes delivery other than in
the form of an interest in this Rule 144A Global Certificate.

            Notwithstanding the preceding paragraph, if this Certificate
constitutes a Rule 144A Global Certificate, then interests herein may be
transferred (without delivery of any certificate or Opinion of Counsel described
in the preceding paragraph) to any Person who takes delivery in the form of a
beneficial interest in the Regulation S Global Certificate of the same Class as
this Rule 144A Global Certificate upon delivery to the Certificate Registrar and
the Trustee of (x) a certificate from the Certificate Owner desiring to effect
such transfer substantially in the form attached as Exhibit F-1D to the
Agreement and a certificate from such Certificate Owner's prospective Transferee
substantially in the form attached as Exhibit F-2D to the Agreement and (y) such
written orders and instructions as are required under the applicable procedures
of DTC, Clearstream and/or Euroclear to direct the Trustee to debit the account
of a Depository Participant by a denomination of interests in this Rule 144A
Global Certificate, and credit the account of a Depository Participant by a
denomination of interests in such Regulation S Global Certificate, that is equal
to the denomination of beneficial interests in such Class to be transferred.
Upon delivery to the Certificate Registrar of such certifications and such
orders and instructions, the Trustee, subject to and in accordance with the
applicable procedures of DTC, shall reduce the denomination of this Rule 144A
Global Certificate, and increase the denomination of the related Regulation S
Global Certificate, by the denomination of the beneficial interest in such Class
specified in such orders and instructions.

            Except as discussed below, if this Certificate constitutes a
Regulation S Global Certificate, then beneficial interests in this Certificate
shall not be transferred to any Person other than a non-United States Securities
Person who takes delivery in the form of a beneficial interest in this
Certificate, and the Certificate Owner desiring to effect such transfer shall be
required to obtain from such Certificate Owner's prospective Transferee a
certification substantially in the form attached as Exhibit F-2D to the
Agreement. On or prior to the Release Date, beneficial interests in any
Regulation S Global Certificate may be held only through Euroclear or
Clearstream. After the Release Date, beneficial interests in any Regulation S
Global Certificate may be held through Euroclear, Clearstream or any other
direct account holder at DTC.

            Notwithstanding the preceding paragraph, if this Certificate
constitutes a Regulation S Global Certificate, then interests in this
Certificate may be transferred (without delivery of any certificate described in
the preceding paragraph) to any Person who takes delivery in the form of a
beneficial interest in the Rule 144A Global Certificate for the same Class as
this Regulation S Global Certificate upon delivery to the Certificate Registrar
and the Trustee of (i) a certificate from the Certificate Owner desiring to
effect such transfer substantially in the form attached as Exhibit F-1C to the
Agreement and a certificate from such Certificate Owner's prospective Transferee
substantially in the form attached as Exhibit F-2C to the Agreement and (ii)
such written orders and instructions as are required under the applicable
procedures of the Depository, Clearstream and/or Euroclear to direct the Trustee
to debit the account of a Depository Participant by a denomination of interests
in this Regulation S Global Certificate, and credit the account of a Depository
Participant by a denomination of interests in such Rule 144A Global Certificate,
that is equal to the denomination of beneficial interests to be transferred.
Upon delivery to the Trustee of such certifications and such orders and
instructions, the Trustee, subject to and in accordance with the applicable
procedures of the Depository, shall reduce the denomination of this Regulation S
Global Certificate, and increase the denomination of the related Rule 144A
Global Certificate, by the denomination of the beneficial interest in such Class
specified in such orders and instructions.

            Notwithstanding the foregoing, any interest in a Global Certificate
may be transferred by any Certificate Owner holding such interest to any Person
who takes delivery in the form of a Definitive Certificate of the same Class as
such Global Certificate upon delivery to the Certificate Registrar and the
Trustee of (i) such certifications and/or opinions as are contemplated above
with respect to transfers of this Certificate in definitive form and (ii) such
written orders and instructions as are required under the applicable procedures
of the Depository, Clearstream and/or Euroclear to direct the Trustee to debit
the account of a Depository Participant by a denomination of interests in such
Global Certificate. Upon delivery to the Certificate Registrar of the
certifications and/or opinions contemplated above with respect to transfers of
this Certificate in definitive form, the Trustee, subject to and in accordance
with the applicable procedures of the Depository, shall reduce the denomination
of the subject Global Certificate, and cause a Definitive Certificate of the
same Class as such Global Certificate, and in a denomination equal to the
reduction in the denomination of such Global Certificate, to be executed,

Certificate Register upon surrender of this Certificate for registration of
transfer at the offices of the Certificate Registrar, duly endorsed by, or

Interest will be issued to the designated transferee or transferees.

            No service charge will be imposed for any registration of transfer
or exchange of this Certificate, but the Trustee or the Certificate Registrar

Loan or REO Property remaining in the Trust Fund, (ii) the purchase by the
NCBFSB Master Servicer, the Co-op Special Servicer, the General Master Servicer,
the General Special Servicer, or any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, at a price determined as
provided in the Agreement, of all the Mortgage Loans and each REO Property
remaining in the Trust Fund and (iii) the acquisition by the Sole
Certificateholder(s) of all the Mortgage Loans and each REO Property remaining

does not require, the NCBFSB Master Servicer, the Co-op Special Servicer, the
General Master Servicer, the General Special Servicer, or any single Controlling
Class Certificateholder or group of Controlling Class Certificateholders to
purchase from the Trust Fund all the Mortgage Loans and each REO Property
remaining therein. The exercise of such right may effect early retirement of the
Certificates; however, such right to purchase is subject to the aggregate Stated
Principal Balance of the Mortgage Pool at the time of purchase being less than
1.0% of the Initial Net Pool Balance.

            The Agreement permits, with certain exceptions therein provided, the

conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of any REMIC Pool as a REMIC, without the consent of the Holders of any
of the Certificates.

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

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

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

certification to the effect that such prospective Transferee is not a Plan and

Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in

entity under the Agreement), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, capitalized
terms used herein have the respective meanings assigned thereto in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

            Pursuant to the terms of the Agreement, beginning on the First
Distribution Date specified above, distributions will be made on that date (the
"Distribution Date") each month that is the fourth Business Day following the
Determination Date in such month, to the Person in whose name this Certificate
is registered at the close of business on the last Business Day of the month

(which wiring instructions may be in the form of a standing order applicable to
all subsequent distributions), or otherwise by check mailed to the address of
such Certificateholder as it appears in the Certificate Register.
Notwithstanding the foregoing, the final distribution on this Certificate will
be made in like manner, but only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar or such other location
specified in the notice to the Holder hereof of such final distribution.

            The Certificates are limited in right of distribution to certain

specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Distribution Account, the Collection Accounts
and, if established, the REO Accounts may be made from time to time for purposes

Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

            This Certificate is issuable in fully registered form only without
coupons. As provided in the Agreement and subject to certain limitations therein
set forth, this Certificate is exchangeable for new Certificates of the same
Class in authorized denominations evidencing the same aggregate Percentage
Interest, as requested by the Holder surrendering the same.

            No transfer, sale, pledge or other disposition of this Certificate
or any interest herein shall be made unless that transfer, sale, pledge or other
disposition is exempt from the registration and/or qualification requirements of
the Securities Act and any applicable state securities laws, or is otherwise
made in accordance with the Securities Act and such state securities laws. If a
transfer of this Certificate is to be made without registration under the
Securities Act, then (except under the limited circumstances specified in the
Agreement) the Certificate Registrar shall refuse to register such transfer
unless it receives (and, upon receipt, may conclusively rely upon) either: (i) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1A to the Agreement; or (ii) a
certificate from the Certificateholder desiring to effect such transfer
substantially in the form attached as Exhibit F-1B to the Agreement and a
certificate from such Certificateholder's prospective Transferee substantially
in the form attached either as Exhibit F-2A or as Exhibit F-2B to the Agreement;
or (iii) an Opinion of Counsel satisfactory to the Trustee to the effect that
such transfer may be made without registration under the Securities Act (which
Opinion of Counsel shall not be an expense of the Trust or of the Depositor, the
General Master Servicer, the NCBFSB Master Servicer, the General Special
Servicer, the Co-op Special Servicer, the Trustee, any Fiscal Agent or the
Certificate Registrar in their respective capacities as such), together with the
written certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based. Any Certificateholder desiring to effect a transfer, sale, pledge or
other disposition of this Certificate or any interest herein shall, and does
hereby agree to, indemnify the Depositor, Credit Suisse First Boston
Corporation, the Trustee, any Fiscal Agent, the General Master Servicer, the
NCBFSB Master Servicer, the General Special Servicer, the Co-op Special
Servicer, and the Certificate Registrar against any liability that may result if
such transfer, sale, pledge or other disposition is not exempt from the
registration and/or qualification requirements of the Securities Act and any
applicable state securities laws or is not made in accordance with such federal
and state laws.

            No transfer of this Certificate or any interest herein shall be made
(A) to any retirement plan or other employee benefit plan or arrangement,
including individual retirement accounts and annuities, Keogh plans and
collective investment funds and separate accounts in which such plans, accounts
or arrangements are invested, including insurance company general accounts, that
is subject to ERISA or Section 4975 of the Code (each, a "Plan"), or (B) to any
Person who is directly or indirectly purchasing this Certificate or any interest
herein on behalf of, as named fiduciary of, as trustee of, or with assets of a
Plan, if the purchase and holding of this Certificate or such interest herein by
the prospective Transferee would result in a violation of Section 406 or 407 of
ERISA or Section 4975 of the Code or would result in the imposition of an excise
tax under Section 4975 of the Code. Except in limited circumstances, the
Certificate Registrar shall refuse to register the transfer of this Certificate
unless it has received from the prospective Transferee either: (i) a
certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing this Certificate on behalf of, as named
fiduciary of, as trustee of, or with assets of a Plan; or (ii) a certification
of facts and an Opinion of Counsel which otherwise establish to the reasonable
satisfaction of the Trustee that such transfer will not result in a violation of
Section 406 or 407 of ERISA or Section 4975 of the Code or result in the
imposition of an excise tax under Section 4975 of the Code.

            Each Person who has or who acquires any Ownership Interest in this
Certificate shall be deemed by its acceptance or acquisition of such Ownership
Interest to have agreed to be bound by the provisions of Section 5.02(d) of the
Agreement and, if any purported Transferee shall become a Holder of this
Certificate in violation of the provisions of such Section 5.02(d), to have
irrevocably authorized the Trustee (i) to deliver payments to a Person other
than such Person and (ii) to negotiate the terms of any mandatory disposition,
to execute all instruments of Transfer and to do all other things necessary in
connection with any such disposition. Each Person holding or acquiring any
Ownership Interest in this Certificate must be a Permitted Transferee and shall
promptly notify the Trustee of any change or impending change in its status as a
Permitted Transferee. In connection with any proposed Transfer of any Ownership
Interest in this Certificate, the Certificate Registrar shall require delivery
to it, and shall not register the Transfer of this Certificate until its receipt
of, an affidavit and agreement substantially in the form attached as Exhibit H-1
to the Agreement (a "Transfer Affidavit and Agreement") from the proposed
Transferee, representing and warranting, among other things, that such
Transferee is a Permitted Transferee, that it is not acquiring its Ownership
Interest in this Certificate as a nominee, trustee or agent for any Person that
is not a Permitted Transferee, that for so long as it retains its Ownership
Interest in this Certificate, it will endeavor to remain a Permitted Transferee,
and that it has reviewed the provisions of Section 5.02(d) of the Agreement and
agrees to be bound by them. Notwithstanding the delivery of a Transfer Affidavit
and Agreement by a proposed Transferee, if a Responsible Officer of either the
Certificate Registrar or Trustee has actual knowledge that the proposed
Transferee is not a Permitted Transferee, no Transfer of an Ownership Interest
in this Certificate to such proposed Transferee shall be effected. In connection
therewith, the Certificate Registrar shall not register the transfer of an
Ownership Interest in this Certificate to any entity classified as a partnership
under the Code unless at the time of transfer, all of its beneficial owners are
United States Persons.

            Each Person holding or acquiring any Ownership Interest in this
Certificate shall agree (x) to require a Transfer Affidavit and Agreement from
any other Person to whom such Person attempts to transfer its Ownership Interest
herein and (y) not to transfer its Ownership Interest herein unless it provides
to the Certificate Registrar a certificate substantially in the form attached as
Exhibit H-2 to the Agreement stating that, among other things, it has no actual
knowledge that such other Person is not a Permitted Transferee. Each Person
holding or acquiring an Ownership Interest in this Certificate, by purchasing
such Ownership Interest herein, agrees to give the Trustee written notice that
it is a "pass-through interest holder" within the meaning of temporary Treasury
regulation Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring such Ownership
Interest, if it is, or is holding such Ownership Interest on behalf of, a
"pass-through interest holder".

            The provisions of Section 5.02(d) of the Agreement may be modified,
added to or eliminated, provided that there shall have been delivered to the
Trustee the following: (a) written confirmation from each Rating Agency to the
effect that the modification of, addition to or elimination of such provisions
will not result in an Adverse Rating Event with respect to any Class of Rated
Certificates; and (b) an Opinion of Counsel, in form and substance satisfactory
to the Trustee, to the effect that such modification of, addition to or
elimination of such provisions will not cause any REMIC Pool to cease to qualify
as a REMIC or be subject to an entity-level tax caused by the Transfer of a
Class R Certificate to a Person that is not a Permitted Transferee, or cause a
Person other than the prospective Transferee to be subject to a REMIC-related
tax caused by the Transfer of a Class R Certificate to a Person that is not a
Permitted Transferee.

            A "Permitted Transferee" is any Transferee other than a
"Disqualified Organization" and a "Non-United States Tax Person". In addition,
if such Transferee is classified as a partnership under the Code, such
Transferee can only be a "Permitted Transferee" if, among other things, all of
its beneficial owners are United States Tax Persons.

            A "Disqualified Organization" is any of (i) the United States or a
possession thereof, any State or political subdivision thereof or any agency or
instrumentality of any of the foregoing (other than an instrumentality which is
a corporation if all of its activities are subject to tax and, except for
Freddie Mac, a majority of its board of directors is not selected by such
governmental unit), (ii) a foreign government, international organization, or
any agency or instrumentality of any of the foregoing, (iii) any organization
(other than certain farmers' cooperatives described in Section 521 of the Code)
which is exempt from the tax imposed by Chapter 1 of the Code (unless such
organization is subject to the tax imposed by Section 511 of the Code on
unrelated business taxable income), (iv) rural electric and telephone
cooperatives described in Section 1381 of the Code and (v) any other Person so
designated by the Trustee based upon an Opinion of Counsel that the holding of
an Ownership Interest in a Class R Certificate by such Person may cause the
Trust or any Person having an Ownership Interest in any Class of Certificates
(other than such Person) to incur a liability for any federal tax imposed under
the Code that would not otherwise be imposed but for the Transfer of an
Ownership Interest in a Class R Certificate to such Person. The terms "United
States", "State" and "international organization" shall have the meanings set
forth in Section 7701 of the Code or successor provisions.

            A "Non-United States Tax Person" is any Person (i) other than a
United States Tax Person or (ii) a United States Tax Person with respect to whom
income from this Certificate is attributable to a foreign permanent
establishment or fixed base, within the meaning of an applicable income tax
treaty, of such person or any other United States Tax Person. A "United States
Tax Person" is a citizen or resident of the United States, a corporation,
partnership or other entity created or organized in, or under the laws of, the
United States or any State thereof or the District of Columbia, or an estate
whose income from sources without the United States is includible in gross
income for United States federal income tax purposes regardless of its
connection with the conduct of a trade or business within the United States, or
a trust if a court within the United States is able to exercise primary
supervision over the administration of the trust and one or more United States
persons have the authority to control all substantial decisions of the trust,
all within the meaning of Section 7701(a)(30) of the Code.

            If a Person is acquiring this Certificate as a fiduciary or agent
for one or more accounts, such Person shall be required to deliver to the
Certificate Registrar a certification to the effect that, and such other
evidence as may be reasonably required by the Trustee to confirm that, it has
(i) sole investment discretion with respect to each such account and (ii) full
power to make the acknowledgments, representations, warranties, certifications
and/or agreements with respect to each such account described above in this
Certificate.

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

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

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

            Subject to certain terms and conditions set forth in the Agreement,
the Trust Fund and the obligations created by the Agreement shall terminate upon
distribution (or provision for distribution) to the Certificateholders of all
amounts held by or on behalf of the Trustee and required to be distributed to
them pursuant to the Agreement following the earlier of (i) the final payment or
other liquidation (or any advance with respect thereto) of the last Mortgage
Loan or REO Property remaining in the Trust Fund, (ii) the purchase by the
NCBFSB Master Servicer, the Co-op Special Servicer, the General Master Servicer,
the General Special Servicer, or any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, at a price determined as
provided in the Agreement, of all the Mortgage Loans and each REO Property
remaining in the Trust Fund and (iii) the acquisition by the Sole
Certificateholder(s) of all the Mortgage Loans and each REO Property remaining
in the Trust Fund in exchange for all of the Certificates. The Agreement
permits, but does not require, the NCBFSB Master Servicer, the Co-op Special
Servicer, the General Master Servicer, the General Special Servicer, or any
single Controlling Class Certificateholder or group of Controlling Class
Certificateholders to purchase from the Trust Fund all the Mortgage Loans and
each REO Property remaining therein. The exercise of such right will effect
early retirement of the Certificates; however, such right to purchase is subject
to the aggregate Stated Principal Balance of the Mortgage Pool at the time of
purchase being less than 1.0% of the Initial Net Pool Balance.

            The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Depositor, the General Master Servicer, the NCBFSB Master Servicer, the General
Special Servicer, the Co-op Special Servicer, the Trustee and any Fiscal Agent
and the rights of the Certificateholders under the Agreement at any time by the
Depositor, the General Master Servicer, the NCBFSB Master Servicer, the General
Special Servicer, the Co-op Special Servicer, the Trustee and any Fiscal Agent
with the consent of the Holders of Certificates entitled to not less than 51% of
the Voting Rights allocated to all of the Classes materially affected by the
amendment. Any such consent by the Holder of this Certificate shall be
conclusive and binding on such Holder and upon all future Holders of this
Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of any REMIC Pool as a REMIC, without the consent of the Holders of any
of the Certificates.

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

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

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

a Pooling and Servicing Agreement, dated as of June 1, 2003 (the "Pooling and

as general master servicer (in such capacity, the "General Master Servicer",

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 Trustee 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

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

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 or the Trustee, 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 in its individual capacity
is 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

and the original or a copy of each document specified in clauses (b)(ii) and
(b)(iii) of the definition of "Mortgage File", have been received by the Trustee
or a Custodian on its behalf; (iii) if such report is due more than 180 days
after the Closing Date, the recordation/filing contemplated by Section 2.01(e)
of the Agreement (except in the case of the Great Lakes Crossing Mortgage Loan)
has been completed (based solely on receipt by the Trustee of the particular
recorded/filed documents or an appropriate receipt of recording/filing
therefor); (iv) all documents received by it or any Custodian with respect to
such Mortgage Loan have been reviewed by it or by such Custodian on its behalf
and (A) appear regular on their face (handwritten additions, changes or
corrections shall not constitute irregularities if initialed by the Borrower),
(B) appear to have been executed and (C) purport to relate to such Mortgage
Loan; and (v) based on the examinations referred to in Section 2.02(a) and
Section 2.02(b) of the Agreement and only as to the foregoing documents, the
information set forth in the Mortgage Loan Schedule with respect to the items
specified in clause (iii)(A) and clause (vi) of the definition of "Mortgage Loan
Schedule" accurately reflects the information set forth in the related Mortgage
File.

            None of the Trustee, the General Master Servicer, the NCBFSB Master
Servicer, the General Special Servicer, the Co-op Special Servicer or any
Custodian is under any duty or obligation to inspect, review or examine any of
the documents, instruments, certificates or other papers relating to the
Mortgage Loans delivered to it to determine that the same are valid, legal,
effective, genuine, binding, enforceable, sufficient or appropriate for the
represented purpose or that they are other than what they purport to be on their
face or to determine whether any of the representations and warranties made by
any Mortgage Loan Seller in their respective Mortgage Loan Purchase Agreement
are true and correct when made. Furthermore, none of the Trustee, the General
Master Servicer, the NCBFSB Master Servicer, the General Special Servicer, the
Co-op Special Servicer or any Custodian shall have any responsibility for
determining whether the text of any assignment or endorsement is in proper or
recordable form, whether the requisite recording of any document is in
accordance with the requirements of any applicable jurisdiction, or whether a
blanket assignment is permitted in any applicable jurisdiction.

            In performing the reviews contemplated by Sections 2.02(a) and
2.02(b) of the Agreement, the Trustee may conclusively rely on the purported
genuineness of any such document and any signature thereon. It is understood
that the scope of the Trustee's review of the Mortgage Files is limited solely
to confirming that the documents specified in clauses (a)(i) through (a)(v),
clause (a)(vii), clause (a)(x), clause (a)(xii), clause (a)(xiii) and, in the
case of any Mortgage Loan secured by a Mortgage on a hospitality property, in
clause (a)(viii) of the definition of "Mortgage File" and any other Specially
Designated Mortgage Loan Documents (without regard to modification agreements
and assumption agreements), have been received and such additional information
as will be necessary for delivering the certifications required by the
Agreement.

            With respect to the documents described in clause (iii) of the
definition of "Mortgage File", absent actual knowledge to the contrary, the
Trustee may assume, for purposes of the certifications delivered pursuant to
Section 2.02(a) of the Agreement or to be delivered pursuant to Section 2.02(b)
of the Agreement, that the Mortgage File for each Mortgage Loan includes a
separate Assignment of Leases.

            Further, with respect to the documents described in clause (viii) of
the definition of "Mortgage File", absent actual knowledge to the contrary or
copies of UCC Financing Statements delivered to the Trustee as part of the
Mortgage File indicating otherwise, the Trustee may assume, for purposes of the
certification(s) to be delivered pursuant to Section 2.02(b) of the Agreement,
that the Mortgage File for each Mortgage Loan should include one state-level UCC
Financing Statement filed in the state of incorporation or organization of the
related Borrower for each Mortgaged Property (or with respect to any Mortgage
Loan that has two or more Borrowers, for each related Borrower).

            Capitalized terms used herein and not otherwise defined shall have
the respective meanings assigned to them in the Agreement.

                                    Respectfully,

                                    WELLS FARGO BANK MINNESOTA, N.A.
                                   as Trustee

                                    By:

            Re:_________________________________________________________________

              __________________________________________________________________

              __________________________________________________________________
                           [Issue description (the "Securities")]

Ladies and Gentlemen:

      This letter sets forth our understanding with respect to certain matters
relating to the Securities. Agent shall act as trustee, paying agent, fiscal
agent, or other such agent of Issuer with respect to the Securities. The
Securities have been issued pursuant to a trust indenture, trust agreement,
pooling and servicing agreement or other such document authorizing the issuance
of the Securities dated _______________ (the "Document").
_______________________________ ["Underwriter/Placement Agent"] is distributing
the Securities through The Depository Trust Company ("DTC").

      To induce DTC to accept the Securities as eligible for deposit at DTC, and
to act in accordance with its Rules with respect to the Securities, Issuer and
Agent make the following representations to DTC:


      1. Prior to closing on the Securities on ____________________ there shall
be deposited with DTC one or more Security certificates registered in the name
of DTC's nominee, Cede & Co., for each stated maturity of the Securities in the
face amounts set forth on Schedule A hereto, the total of which represents 100%
of the principal amount of such Securities. If, however, the aggregate principal
amount of any maturity exceeds $400 million, one certificate shall be issued
with respect to each $400 million of principal amount and an additional
certificate shall be issued with respect to any remaining principal amount. Each
Security certificate shall bear the following legend:

            Unless this certificate is presented by an authorized representative
      of The Depository Trust Company, a New York corporation ("DTC"), to Issuer
      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.

Issuer represents: [Note: Issuer must represent one of the following, and shall
cross out the other.]

      [The Security certificate(s) shall remain in Agent's custody as a "Balance
Certificate" subject to the provisions of the Balance Certificate Agreement
between Agent and DTC currently in effect.

      On each day on which Agent is open for business and on which it receives
an instruction originated by a DTC participant ("Participant") through DTC's
Deposit/Withdrawal at Custodian ("DWAC") system to increase the Participant's
account by a specified number of Securities (a "Deposit Instruction"), Agent
shall, no later than 6:30 p.m. (Eastern Time) that day, either approve or cancel
the Deposit Instruction through the DWAC system.

      On each day on which Agent is open for business and on which it receives
an instruction originated by Participant through the DWAC system to decrease the
Participant's account by a specified number of Securities (a "Withdrawal
Instruction"), Agent shall, no later than 6:30 p.m. (Eastern Time) that day,
either approve or cancel the Withdrawal Instruction through the DWAC system.

      Agent agrees that its approval of a Deposit or Withdrawal Instruction
shall be deemed to be the receipt by DTC of a new reissued or reregistered
certificated Security on registration of transfer to the name of Cede & Co. for
the quantity of Securities evidenced by the Balance Certificate after the
Deposit or Withdrawal Instruction is effected.]

      [The Security certificate(s) shall be custodied with DTC.]

      2. Issuer: (a) understands that DTC has no obligation to, and will not,
communicate to its Participants or to any person having an interest in the
Securities any information contained in the Security certificate(s); and (b)
acknowledges that neither DTC's Participants nor any person having an interest
in the Securities shall be deemed to have notice of the provisions of the
Security certificates by virtue of submission of such certificate(s) to DTC.

      3. In the event of any solicitation of consents from or voting by holders
of the Securities, Issuer or Agent shall establish a record date for such
purposes (with no provision for revocation of consents or votes by subsequent
holders) and shall send notice of such record date to DTC no fewer than 15
calendar days in advance of such record date. Notices to DTC pursuant to this
Paragraph by telecopy shall be directed to DTC's Reorganization Department,
Proxy Unit at (212) 855-5181 or (212) 855-5182. If the party sending the notice
does not receive a telecopy receipt from DTC confirming that the notice has been
received, such party shall telephone (212) 855-5202. Notices to DTC pursuant to
this Paragraph, by mail or by any other means, shall be sent to:

                              Supervisor,
                              Proxy Unit Reorganization Department
                              The Depository Trust Company
                              55 Water Street 50th Floor
                              New York, NY 10041-0099

      4. In the event of a full or partial redemption, Issuer or Agent shall
send a notice to DTC specifying: (a) the amount of the redemption or refunding;
(b) in the case of a refunding, the maturity date(s) established under the
refunding; and (c) the date such notice is to be distributed to Security holders
(the "Publication Date"). Such notice shall be sent to DTC by a secure means
(e.g., legible telecopy, registered or certified mail, overnight delivery) in a
timely manner designed to assure that such notice is in DTC's possession no
later than the close of business on the business day before or, if possible, two
business days before the Publication Date. Issuer or Agent shall forward such
notice either in a separate secure transmission for each CUSIP number or in a
secure transmission for multiple CUSIP numbers (if applicable) which includes a
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such
means and the timeliness of such notice.) The Publication Date shall be no fewer
than 30 days nor more than 60 days prior to the redemption date or, in the case
of an advance refunding, the date that the proceeds are deposited in escrow.
Notices to DTC pursuant to this Paragraph by telecopy shall be directed to DTC's
Call Notification Department at (516) 227- 4164 or (516) 227-4190. If the party
sending the notice does not receive a telecopy receipt from DTC confirming that
the notice has been received, such party shall telephone (516) 227-4070. Notices
to DTC pursuant to this Paragraph, by mail or by any other means, shall be sent
to:

                              Manager, Call Notification Department
                              The Depository Trust Company
                              711 Stewart Avenue
                              Garden City, NY 11530-4719

      5. In the event of an invitation to tender the Securities (including
mandatory tenders, exchanges, and capital changes), notice by Issuer or Agent to
Security holders shall be sent to DTC specifying the terms of the tender and the
Publication Date of such notice. Such notice shall be sent to DTC by a secure
means (e.g., legible telecopy, registered or certified mail, overnight delivery)
in a timely manner designed to assure that such notice is in DTC's possession no
later than the close of business on the business day before or, if possible, two
business days before the Publication Date. Issuer or Agent shall forward such
notice either in a separate secure transmission for each CUSIP number or in a
secure transmission for multiple CUSIP numbers (if applicable) which includes a
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use and
timeliness of such notice.) Notices to DTC pursuant to this Paragraph and
notices of other corporate actions by telecopy shall be directed to DTC's
Reorganization Department at (212) 855-5488. If the party sending the notice
does not receive a telecopy receipt from DTC confirming that the notice has been
received, such party shall telephone (212) 855-5290. Notices to DTC pursuant to
this Paragraph, by mail or by any other means, shall be sent to:

                              Manager, Reorganization Department
                              Reorganization Window

                              New York, NY 10041-0099

      6. It is understood that if the Security holders shall at any time have
the right to tender the Securities to Issuer and require that Issuer repurchase
such holders' Securities pursuant to the Document and Cede & Co., as nominee of
DTC, or its registered assigns, as the record owner, is entitled to tender the
Securities, such tenders will be effected by means of DTC's Repayment Option
Procedures. Under the Repayment Option Procedures, DTC shall receive, during the
applicable tender period, instructions from its Participants to tender
Securities for purchase. Issuer and Agent agree that such tender for purchase
may be made by DTC by means of a book-entry credit of such Securities to the
account of Agent, provided that such credit is made on or before the final day
of the applicable tender period. DTC agrees that promptly after the recording of
any such book-entry credit, it will provide to Agent an Agent Receipt and
Confirmation or the equivalent, in accordance with the Repayment Option
Procedures, identifying the Securities and the aggregate principal amount
thereof as to which such tender for purchase has been made.

      Agent shall send DTC notice regarding such optional tender by hand or by a
secure means (e.g., legible facsimile transmission, registered or certified
mail, overnight delivery) in a timely manner designed to assure that such notice
is in DTC's possession no later than the close of business two business days
before the Publication Date. The Publication Date shall be no fewer than 15 days
prior to the expiration date of the applicable tender period. Such notice shall
state whether any partial redemption of the Securities is scheduled to occur
during the applicable optional tender period. Notices to DTC pursuant to this
Paragraph by telecopy shall be directed to DTC's Put Bond Unit at (212)
855-5235. If the party sending the notice does not receive a telecopy receipt
from DTC confirming that the notice has been received, such party shall
telephone (212) 855-5230. Notices to DTC pursuant to this Paragraph, by mail or
by any other means, shall be sent to:

                              Supervisor, Put Bond Unit
                              Reorganization Department

                              New York, NY 10041-0099

      7. All notices and payment advices sent to DTC shall contain the CUSIP
number of the Securities.

      8. Issuer or Agent shall send DTC written notice with respect to the

allocated as to the interest and principal portions thereof preferably five, but
no fewer than two, business days prior to such payment date. Such notices, which
shall also contain the current pool factor, any special adjustments to
principal/interest rates (e.g., adjustments due to deferred interest or
shortfall), and Agent contact's name and telephone number, shall be sent by
telecopy to DTC's Dividend Department at (212) 855-4555, and receipt of such
notices shall be confirmed by telephoning (212) 855-4550. Notices to DTC,
pursuant to this Paragraph, by mail or by any other means, shall be sent to:

      10. Issuer or Agent shall provide a written notice of interest payment
information, including the stated coupon rate information, to DTC as soon as the
information is available. Issuer or Agent shall provide such notice directly to
DTC electronically, as previously arranged by Issuer or Agent and DTC. If
electronic transmission has not been arranged, absent any other arrangements
between Issuer or Agent and DTC, such information shall be sent by telecopy to
DTC's Dividend Department at (212) 855-4555 or (212) 855-4556. If the party
sending the notice does not receive a telecopy receipt from DTC confirming that
the notice has been received, such party shall telephone (212) 855-4550. Notices
to DTC pursuant to this Paragraph, by mail or by any other means, shall be sent
to DTC's Dividend Department as indicated in Paragraph 8.

      11. Interest payments and principal payments that are part of periodic
principal-andinterest payments shall be received by Cede & Co., as nominee of
DTC, or its registered assigns, in same-day funds no later than 2:30 p.m.
(Eastern Time) on each payment date. Issuer shall remit by 1:00 p.m. (Eastern
Time) on the payment date all such interest payments due Agent, or at such
earlier time as may be required by Agent to guarantee that DTC shall receive
payment in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment
date. Absent any other arrangements between Issuer or Agent and DTC, such funds
shall be wired to the Dividend Deposit Account number that will be stamped on
the signature page hereof at the time DTC executes this Letter of
Representations.

      12. Issuer or Agent shall provide DTC's Dividend Department, no later than
12:00 noon (Eastern Time) on the payment date, automated notification of
CUSIP-level detail. If the circumstances prevent the funds paid to DTC from
equaling the dollar amount associated with the detail payments by 12:00 noon
(Eastern Time), Issuer or Agent must provide CUSIP-level reconciliation to DTC
no later than 2:30 p.m. (Eastern Time). Reconciliation must be provided by
either automated means or written format. Such reconciliation notice, if sent by
telecopy, shall be directed to DTC Dividend Department at (212) 855-4633 and
receipt of such reconciliation notice shall be confirmed by telephoning (212)
855-4430.

      13. Maturity and redemption payments allocated with respect to each CUSIP
number shall be received by Cede & Co., as nominee of DTC, or its registered
assigns, in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment
date. Issuer shall remit by 1:00 p.m. (Eastern Time) on the payment date all
such maturity and redemption payments due Agent, or at such earlier time as
required by Agent to guarantee that DTC shall receive payment in same-day funds
no later than 2:30 p.m. (Eastern Time) on the payment date. Absent any other
arrangements between Issuer or Agent and DTC, such funds shall be wired to the
Redemption Deposit Account number that will be stamped on the signature page
hereof at the time DTC executes this Letter of Representations.

      14. Principal payments (plus accrued interest, if any) as the result of
optional tenders for purchase effected by means of DTC's Repayment Option
Procedures shall be received by Cede & Co., as nominee of DTC, or its registered
assigns, in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment
date. Issuer shall remit by 1:00 p.m. (Eastern Time) on the payment date all
such reorganization payments due Agent, or at such earlier time as required by
Agent to guarantee that DTC shall receive payment in same-day funds no later
than 2:30 p.m. (Eastern Time) on the payment date. Absent any other arrangements
between Issuer or Agent and DTC, such funds shall be wired to the Reorganization
Deposit Account number that will be stamped on the signature page hereof at the
time DTC executes this Letter of Representations.

      15. Agent shall send DTC all periodic certificate holders remittance
reports with respect to the Securities. If sent by facsimile transmission, such
reports shall be sent to (212) 855- 4777. If the party sending the report does
not receive a telecopy receipt from DTC confirming that the notice has been
received, such party shall telephone (212) 855-4590.

      16. DTC may direct Issuer or Agent to use any other number or address as
the number or address to which notices or payments of interest or principal may
be sent.

      17. In the event of a redemption, acceleration, or any other similar
transaction (e.g., tender made and accepted in response to Issuer's or Agent's
invitation) necessitating a reduction in the aggregate principal amount of
Securities outstanding or an advance refunding of part of the Securities
outstanding, DTC, in its discretion: (a) may request Issuer or Agent to issue
and authenticate a new Security certificate; or (b) may make an appropriate
notation on the Security certificate indicating the date and amount of such
reduction in principal except in the case of final maturity, in which case the
certificate will be presented to Issuer or Agent prior to payment, if required.

      18. In the event that Issuer determines that beneficial owners of
Securities shall be able to obtain certificated Securities, Issuer or Agent
shall notify DTC of the availability of certificates. In such event, Issuer or
Agent shall issue, transfer, and exchange certificates in appropriate amounts,
as required by DTC and others.

      19. DTC may discontinue providing its services as securities depository
with respect to the Securities at any time by giving reasonable notice to Issuer
or Agent (at which time DTC will confirm with Issuer or Agent the aggregate
principal amount of Securities outstanding). Under such circumstances, at DTC's
request Issuer and Agent shall cooperate fully with DTC by taking appropriate
action to make available one or more separate certificates evidencing Securities
to any Participant having Securities credited to its DTC accounts.

      20. Nothing herein shall be deemed to require Agent to advance funds on
behalf of Issuer.

      21. This Letter of Representations may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original,
but all such counterparts together shall constitute but one and the same
instrument.

      22. This Letter of Representations shall be governed by, and construed in
accordance with, the laws of the State of New York, without giving effect to
principles of conflicts of law.

      23. The sender of each notice delivered to DTC pursuant to this Letter of
Representations is responsible for confirming that such notice was properly
received by DTC.

      24. Issuer recognizes that DTC does not in any way undertake to, and shall
not have any responsibility to, monitor or ascertain the compliance of any
transactions in the Securities with the following, as amended from time to time:
(a) any exemptions from registration under the Securities Act of 1933; (b) the
Investment Company Act of 1940; (c) the Employee Retirement Income Security Act
of 1974; (d) the Internal Revenue Code of 1986; (e) any rules of any
selfregulatory organizations (as defined under the Securities Exchange Act of
1934); or (f) any other local, state, or federal laws or regulations thereunder.

      25. Issuer hereby authorizes DTC to provide to Agent listings of
Participants' holdings, known as Securities Position Listings ("SPLs") with
respect to the Securities from time to time at the request of the Agent. DTC
charges a fee for such SPLs. This authorization, unless revoked by Issuer, shall
continue with respect to the Securities while any Securities are on deposit at
DTC, until and unless Agent shall no longer be acting. In such event, Issuer
shall provide DTC with similar evidence, satisfactory to DTC, of the
authorization of any successor thereto so to act. Requests for SPLs shall be
sent by telecopy to the Proxy Unit of DTC's Reorganization Department at (212)
855-5181 or (212) 855-5182. Receipt of such requests shall be confirmed by
telephoning (212) 855-5202. Requests for SPLs, sent by mail or by any other
means, shall be directed to the address indicated in Paragraph 3.

      26. Issuer and Agent shall comply with the applicable requirements stated
in DTC's Operational Arrangements, as they may be amended from time to time.
DTC's Operational Arrangements are posted on DTC's website at "www.DTC.org."

      27. The following rider(s), attached hereto, are hereby incorporated into
this Letter of Representations:

                                                                      ----------

                       SAMPLE OFFERING DOCUMENT LANGUAGE
                      DESCRIBING BOOK-ENTRY-ONLY ISSUANCE
                  --------------------------------------------

 (Prepared by DTC--bracketed material may be applicable only to certain issues)

      1. The Depository Trust Company ("DTC"), New York, NY, will act as
securities depository for the securities (the "Securities"). The Securities will
be issued as fully-registered securities registered in the name of Cede & Co.
(DTC's partnership nominee) or such other name as may be requested by an
authorized representative of DTC. One fully-registered Security certificate will
be issued for [each issue of] the Securities, [each] in the aggregate principal
amount of such issue, and will be deposited with DTC. [If, however, the
aggregate principal amount of [any] issue exceeds $400 million, one certificate
will be issued with respect to each $400 million of principal amount and an
additional certificate will be issued with respect to any remaining principal
amount of such issue.]

      2. DTC is a limited-purpose trust company organized under the New York
Banking Law, a "banking organization" within the meaning of the New York Banking
Law, a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants ("Direct Participants")
deposit with DTC. DTC also facilitates the settlement among Direct Participants
of securities transactions, such as transfers and pledges, in deposited
securities through electronic computerized book-entry changes in Direct
Participants' accounts, thereby eliminating the need for physical movement of
securities certificates. Direct Participants include securities brokers and
dealers, banks, trust companies, clearing corporations, and certain other
organizations. DTC is owned by a number of its Direct Participants and by the
New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National
Association of Securities Dealers, Inc. Access to the DTC system is also
available to others such as securities brokers and dealers, banks, and trust
companies that clear through or maintain a custodial relationship with a Direct
Participant, either directly or indirectly ("Indirect Participants"). The Rules
applicable to DTC and its Direct and Indirect Participants are on file with the
Securities and Exchange Commission.

      3. Purchases of Securities under the DTC system must be made by or through
Direct Participants, which will receive a credit for the Securities on DTC's
records. The ownership interest of each actual purchaser of each Security
("Beneficial Owner") is in turn to be recorded on the Direct and Indirect
Participants' records. Beneficial Owners will not receive written confirmation
from DTC of their purchase, but Beneficial Owners are expected to receive
written confirmations providing details of the transaction, as well as periodic
statements of their holdings, from the Direct or Indirect Participant through
which the Beneficial Owner entered into the transaction. Transfers of ownership
interests in the Securities are to be accomplished by entries made on the books
of Direct and Indirect Participants acting on behalf of Beneficial Owners.
Beneficial Owners will not receive certificates representing their ownership
interests in Securities, except in the event that use of the book-entry system
for the Securities is discontinued.

      4. To facilitate subsequent transfers, all Securities deposited by Direct
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. or such other name as may be requested by an authorized
representative of DTC. The deposit of Securities with DTC and their registration
in the name of Cede & Co. or such other nominee do not effect any change in
beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of
the Securities; DTC's records reflect only the identity of the Direct
Participants to whose accounts such Securities are credited, which may or may
not be the Beneficial Owners. The Direct and Indirect Participants will remain
responsible for keeping account of their holdings on behalf of their customers.

      5. Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time. [Beneficial Owners of Securities may wish to
take certain steps to augment transmission to them of notices of significant
events with respect to the Securities, such as redemptions, tenders, defaults,
and proposed amendments to the security documents. Beneficial Owners of
Securities may wish to ascertain that the nominee holding the Securities for
their benefit has agreed to obtain and transmit notices to Beneficial Owners, or
in the alternative, Beneficial Owners may wish to provide their names and
addresses to the registrar and request that copies of the notices be provided
directly to them.]

      [6. Redemption notices shall be sent to DTC. If less than all of the
Securities within an issue are being redeemed, DTC's practice is to determine by
lot the amount of the interest of each Direct Participant in such issue to be
redeemed.]

      7. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or
vote with respect to the Securities. Under its usual procedures, DTC mails an
Omnibus Proxy to Issuer as soon as possible after the record date. The Omnibus
Proxy assigns Cede & Co.'s consenting or voting rights to those Direct
Participants to whose accounts the Securities are credited on the record date
(identified in a listing attached to the Omnibus Proxy).

      8. Redemption proceeds, distributions, and dividend payments on the
Securities will be made to Cede & Co., or such other nominee as may be requested
by an authorized representative of DTC. DTC's practice is to credit Direct
Participants' accounts, upon DTC's receipt of funds and corresponding detail
information from Issuer or Agent on payable date in accordance with their
respective holdings shown on DTC's records. Payments by Participants to
Beneficial Owners will be governed by standing instructions and customary
practices, as is the case with securities held for the accounts of customers in
bearer form or registered in "street name," and will be the responsibility of
such Participant and not of DTC, Agent, or Issuer, subject to any statutory or
regulatory requirements as may be in effect from time to time. Payment of
redemption proceeds, distributions, and dividends to Cede & Co. (or such other
nominee as may be requested by an authorized representative of DTC) is the
responsibility of Issuer or Agent, disbursement of such payments to Direct
Participants shall be the responsibility of DTC, and disbursement of such
payments to the Beneficial Owners shall be the responsibility of Direct and
Indirect Participants.

      [9. A Beneficial Owner shall give notice to elect to have its Securities
purchased or tendered, through its Participant, to [Tender/Remarketing] Agent,
and shall effect delivery of such Securities by causing the Direct Participant
to transfer the Participant's interest in the Securities, on DTC's records, to
[Tender/Remarketing] Agent. The requirement for physical delivery of Securities
in connection with an optional tender or a mandatory purchase will be deemed
satisfied when the ownership rights in the Securities are transferred by Direct
Participants on DTC's records and followed by a book-entry credit of tendered
Securities to [Tender/Remarketing] Agent's DTC account.]

      10. DTC may discontinue providing its services as securities depository
with respect to the Securities at any time by giving reasonable notice to Issuer
or Agent. Under such circumstances, in the event that a successor securities
depository is not obtained, Security certificates are required to be printed and
delivered.

      11. Issuer may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository). In that event,
Security certificates will be printed and delivered.

      12. The information in this section concerning DTC and DTC's book-entry
system has been obtained from sources that Issuer believes to be reliable, but
Issuer takes no responsibility for the accuracy thereof.

      FORM OF CMSA SERVICER WATCH LIST CRITERIA FOR CO-OP MORTGAGE LOANS

      (i)   A loan that has a then current debt service coverage ratio that is
            less than 0.9x;

     (ii)   A loan as to which any required inspection of the related property
            conducted by the NCBFSB Master Servicer indicates, or the NCBFSB
            Master Servicer otherwise has actual knowledge of, a problem that
            the NCBFSB Master Servicer determines can reasonably be expected to
            materially adversely affect the cash flow generated by such
            property;

    (iii)   A loan as to which the NCBFSB Master Servicer has actual knowledge
            of material damage or waste at the related property;

     (iv)   A loan as to which it has come to the NCBFSB Master Servicer's
            attention in the performance of its duties that any tenant or
            tenants occupying 25% or more of the space in, or responsible for
            20% or more of total rental revenue from, the related property (A)
            has or have vacated such space (without being replaced by a
            comparable tenant and lease) or (B) has or have declared bankruptcy;

      (v)   A loan that is at least 30 days delinquent in payment (without
            regard to any grace period);

     (vi)   A loan as to which the net operating income or net cash flow, as
            applicable, as stated in the most recent twelve-month operating
            statement has decreased 25% or more from the net operating income or
            net cash flow, as the case may be, at origination;

    (vii) A loan that is within 90 days of maturity;

   (viii)   A loan as to which the NCBFSB Master Servicer has determined,
            consistent with the Servicing Standard, that a payment default is
            reasonably likely to occur because the annual maintenance on the
            related property is more than 5% in arrears, such arrearage has
            continued for four or more months and the related borrower has less
            than 10% of the annual maintenance in reserve; and

     (ix)   A loan as to which any material deferred maintenance is identified
            by the NCBFSB Master Servicer at the related property and such
            deferred maintenance is not cured within 120 days of the
            identification thereof.

For purposes of item "(i)" above, debt service coverage ratio shall mean, as of
the date of any determination, the net operating income for the trailing 12
month period for the related property (based on actual receipt of maintenance
payments from tenant-shareholders less actual operating expenses for the related
period, all as set forth in the most recent annual financial statement submitted
by the borrower) divided by the actual aggregate mortgage payments for such
period.

      Re:   Credit Suisse First Boston Mortgage Securities Corp., Commercial
            Mortgage Pass-Through Certificates, Series 2003-C3, Class ______
            Certificates [having an initial aggregate Certificate [Principal
            Balance] [Notional Amount] as of June 27, 2003 (the "Closing Date")
            of $__________] [evidencing a ____% Percentage Interest in the
            related Class] (the "Transferred Certificates")
            ------------------------------------------------------------------

Dear Sirs:

      This letter is delivered to you in connection with the transfer by
_________________ (the "Transferor") to _________________ (the "Transferee") of
the Transferred Certificates pursuant to Section 5.02 of the Pooling and
Servicing Agreement dated as of June 1, 2003 (the "Pooling and Servicing
Agreement"), among Credit Suisse First Boston Mortgage Securities Corp. as
depositor, KeyCorp Real Estate Capital Markets, Inc., as general master servicer
(in such capacity, the "General Master Servicer"), ARCap Servicing, Inc., as
general special servicer (in such capacity, the "General Special Servicer"),
NCB, FSB, as NCBFSB master servicer (in such capacity, the "NCBFSB Master
Servicer"), National Consumer Cooperative Bank, as co-op special servicer (in
such capacity, the "Co-op Special Servicer") and Wells Fargo Bank Minnesota,
N.A., as trustee (in such capacity, the "Trustee"). All capitalized terms used
herein and not otherwise defined shall have the respective meanings set forth in
the Pooling and Servicing Agreement. The Transferor hereby certifies, represents
and warrants to you, as Certificate Registrar, that:

1. The Transferor is the lawful owner of the Transferred Certificates with the
full right to transfer such Certificates free from any and all claims and
encumbrances whatsoever.

2. Neither the Transferor nor anyone acting on its behalf has (a) offered,
transferred, pledged, sold or otherwise disposed of any Transferred Certificate,
any interest in a Transferred Certificate or any other similar security to any
person in any manner, (b) solicited any offer to buy or accept a transfer,
pledge or other disposition of any Transferred Certificate, any interest in a
Transferred Certificate or any other similar security from any person in any
manner, (c) otherwise approached or negotiated with respect to any Transferred
Certificate, any interest in a Transferred Certificate or any other similar
security with any person in any manner, (d) made any general solicitation with
respect to any Transferred Certificate, any interest in a Transferred
Certificate or any other similar security by means of general advertising or in
any other manner, or (e) taken any other action with respect to any Transferred
Certificate, any interest in a Transferred Certificate or any other similar
security, which (in the case of any of the acts described in clauses (a) through
(e) hereof) would constitute a distribution of the Transferred Certificates
under the Securities Act of 1933, as amended (the "Securities Act"), or would
render the disposition of the Transferred Certificates a violation of Section 5
of the Securities Act or any state securities laws, or would require
registration or qualification of the Transferred Certificates pursuant to the
Securities Act or any state securities laws.

3. The Transferor and any person acting on behalf of the Transferor in this
matter reasonably believe that the Transferee is a "qualified institutional
buyer" as that term is defined in Rule 144A ("Rule 144A") under the Securities
Act (a "Qualified Institutional Buyer") purchasing for its own account or for
the account of another person that is itself a Qualified Institutional Buyer. In
determining whether the Transferee is a Qualified Institutional Buyer, the
Transferor and any person acting on behalf of the Transferor in this matter has
relied upon the following method(s) of establishing the Transferee's ownership
and discretionary investments of securities (check one or more):

      ___ (a) The Transferee's most recent publicly available financial
      statements, which statements present the information as of a date within
      16 months preceding the date of sale of the Transferred Certificates in
      the case of a U.S. purchaser and within 18 months preceding such date of
      sale in the case of a foreign purchaser; or

      ___ (b) The most recent publicly available information appearing in
      documents filed by the Transferee with the Securities and Exchange
      Commission or another United States federal, state, or local governmental
      agency or self-regulatory organization, or with a foreign governmental
      agency or self-regulatory organization, which information is as of a date
      within 16 months preceding the date of sale of the Transferred
      Certificates in the case of a U.S. purchaser and within 18 months
      preceding such date of sale in the case of a foreign purchaser; or

      ___ (c) The most recent publicly available information appearing in a
      recognized securities manual, which information is as of a date within 16
      months preceding the date of sale of the Transferred Certificates in the
      case of a U.S. purchaser and within 18 months preceding such date of sale
      in the case of a foreign purchaser; or

      ___ (d) A certification by the chief financial officer, a person
      fulfilling an equivalent function, or other executive officer of the
      Transferee, specifying the amount of securities owned and invested on a
      discretionary basis by the Transferee as of a specific date on or since
      the close of the Transferee's most recent fiscal year, or, in the case of
      a Transferee that is a member of a "family of investment companies", as
      that term is defined in Rule 144A, a certification by an executive officer
      of the investment adviser specifying the amount of securities owned by the
      "family of investment companies" as of a specific date on or since the
      close of the Transferee's most recent fiscal year.

      ___   (e)   Other.  (Please specify brief description of method)__________
                  ______________________________________________________________
                  ______________________________________________________________


4.    The Transferor and any person acting on behalf of the Transferor
      understand that in determining the aggregate amount of securities owned
      and invested on a discretionary basis by an entity for purposes of
      establishing whether such entity is a Qualified Institutional Buyer:

(a)   the following instruments and interests shall be excluded: securities of
      issuers that are affiliated with such entity; securities that are part of
      an unsold allotment to or subscription by such entity, if such entity is a
      dealer; securities of issuers that are part of such entity's "family of
      investment companies", if such entity is a registered investment company;
      bank deposit notes and certificates of deposit; loan participations;
      repurchase agreements; securities owned but subject to a repurchase
      agreement; and currency, interest rate and commodity swaps;

(b)   the aggregate value of the securities shall be the cost of such
      securities, except where the entity reports its securities holdings in its
      financial statements on the basis of their market value, and no current
      information with respect to the cost of those securities has been
      published, in which case the securities may be valued at market; and

(c)   securities owned by subsidiaries of the entity that are consolidated with
      the entity in its financial statements prepared in accordance with
      generally accepted accounting principles may be included if the
      investments of such subsidiaries are managed under the direction of the
      entity, except that, unless the entity is a reporting company under
      Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended,
      securities owned by such subsidiaries may not be included if the entity
      itself is a majority-owned subsidiary that would be included in the
      consolidated financial statements of another enterprise.

5.    The Transferor or a person acting on its behalf has taken reasonable steps
      to ensure that the Transferee is aware that the Transferor is relying on
      the exemption from the provisions of Section 5 of the Securities Act
      provided by Rule 144A.

6.    The Transferor or a person acting on its behalf has furnished, or caused
      to be furnished, to the Transferee all information regarding (a) the
      Depositor, (b) the Transferred Certificates and distributions thereon, (c)
      the nature, performance and servicing of the Mortgage Loans, (d) the
      Pooling and Servicing Agreement, and (e) all related matters, that the
      Transferee has requested.

                                    Very truly yours,

Ladies and Gentlemen:

      This letter is delivered to you in connection with the Transfer by
______________________ (the "Transferor") to ______________________ (the
"Transferee") through our respective Depository Participants of the Transferor's
beneficial ownership interest (currently maintained on the books and records of
The Depository Trust Company ("DTC") and the Depository Participants) in the
Transferred Certificates. The Certificates, including the Transferred
Certificates, were issued pursuant to the Pooling and Servicing Agreement dated
as of June 1, 2003 (the "Pooling and Servicing Agreement"), among Credit Suisse
First Boston Mortgage Securities Corp. as depositor, KeyCorp Real Estate Capital
Markets, Inc., as general master servicer (in such capacity, the "General Master

and Wells Fargo Bank Minnesota, N.A., as trustee (in such capacity, the
"Trustee"). All capitalized terms used but not otherwise defined herein shall
have the respective meanings set forth in the Pooling and Servicing Agreement.
The Transferor hereby certifies, represents and warrants to and agrees with you,
as Certificate Registrar, and for the benefit of the Depositor and the Trustee,
that:

1.    The Transferor is the lawful owner of the Transferred Certificates with
      the full right to transfer such Certificates free from any and all claims
      and encumbrances whatsoever.

2.    At the time the buy order was originated, the Transferor reasonably
      believed that the Transferee was outside the United States, its
      territories and possessions.

3.    If the Transferor is a distributor (within the meaning of Rule 902(d)
      under the Securities Act of 1933, as amended (the "Securities Act")) with
      respect to the Transferred Certificates, or an affiliate of such a
      distributor or of the Depositor, or a person acting on behalf of such a
      distributor, the Depositor or any affiliate of such distributor or of the
      Depositor, then:

(a)   the sale of the Transferred Certificates by the Transferor to the
      Transferee will be executed in, on or through a physical trading floor of
      an established foreign securities exchange that is located outside the
      United States, its territories and possessions;

(b)   no directed selling efforts (within the meaning of Rule 902(c) under the
      Securities Act) have been made in the United States, its territories and
      possessions, with respect to the Transferred Certificates by the
      Transferor, any of its affiliates, or any person acting on behalf of any
      of the foregoing;

(c)   all offers and sales, if any, of the  Transferred  Certificates by or on
      behalf of the  Transferor  prior to the  expiration of the  distribution
      compliance  period  specified  in category 2 or 3  (paragraph  (b)(2) or
      (b)(3)) in Rule 903 under the Securities  Act, as applicable,  have been
      and will be made only in accordance  with the  provisions of Rule 903 or
      Rule 904 under the  Securities  Act,  pursuant  to  registration  of the
      Transferred  Certificates  under the  Securities  Act, or pursuant to an
      available   exemption  from  the   registration   requirements   of  the
      Securities Act;

(d)   all offering materials and documents (other than press releases), if any,
      used in connection with offers and sales of the Transferred Certificates
      by or on behalf of the Transferor prior to the expiration of the
      distribution compliance period specified in category 2 or 3 (paragraph
      (b)(2) or (b)(3)) in Rule 903 under the Securities Act, as applicable,
      complied with the requirements of Rule 902(g)(2) under the Securities Act;
      and

(e)   if the Transferee is a distributor, a dealer or a person receiving a
      selling concession, a fee or other remuneration and the offer or sale of
      the Transferred Certificates thereto occurs prior to the expiration of the
      applicable 40-day distribution compliance period, the Transferor has sent
      a confirmation or other notice to the Transferee that the Transferee is
      subject to the same restrictions on offers and sales that apply to a
      distributor.

4.    If the Transferor is not a distributor with respect to the Transferred
      Certificates or an affiliate of such a distributor or of the Depositor or
      acting on behalf of such a distributor, the Depositor or any affiliate of
      such a distributor or of the Depositor, then:

(a)   the sale of the Transferred Certificates by the Transferor to the
      Transferee will be executed in, on or through the facilities of a
      designated offshore securities market described in paragraph (b) of Rule
      902 under the Securities Act, and neither the Transferor nor anyone acting
      on its behalf knows that such transaction has been prearranged with a
      buyer in the United States, its territories and possessions;

(b)   no directed selling efforts (within the meaning of Rule 902(c) under the
      Securities Act) have been made in the United States, its territories and
      possessions, with respect to the Transferred Certificates by the
      Transferor, any of its affiliates, or any person acting on behalf of any
      of the foregoing;

(c)   if the Transferee is a dealer or a person receiving a selling concession,
      a fee or other remuneration and the offer or sale of the Transferred
      Certificates thereto occurs prior to the expiration of the applicable
      40-day distribution compliance period, the Transferor has sent a
      confirmation or other notice to the Transferee stating that the
      Transferred Certificates may be offered and sold during the distribution
      compliance period only in accordance with the provisions of Regulation S
      under the Securities Act, pursuant to registration of the Transferred
      Certificates under the Securities Act or pursuant to an available
      exemption from the registration requirements of the Securities Act.


                                    Very truly yours,

            commissioner or a similar official or agency of a State, U.S.

            cross-reference to the paragraph and subparagraph under subsection
            (a)(1) of Rule 144A pursuant to which it qualifies. Note that

3. For purposes of determining the aggregate amount of securities owned and/or

4. For purposes of determining the aggregate amount of securities owned and/or

such securities to such Person, unless such Person reports its securities
holdings in its financial statements on the basis of their market value, and no
current information with respect to the cost of those securities has been
published, in which case the securities were valued at market. Further, in
determining such aggregate amount, the Transferee may have included securities
owned by subsidiaries of such Person, but only if such subsidiaries are
consolidated with such Person in its financial statements prepared in accordance
with generally accepted accounting principles and if the investments of such
subsidiaries are managed under such Person's direction. However, such securities
were not included if such Person is a majority-owned, consolidated subsidiary of
another enterprise and such Person is not itself a reporting company under the
Securities Exchange Act of 1934, as amended.

5. The Transferee is familiar with Rule 144A and understands that the Transferor
and other parties related to the Transferred Certificates are relying and will
continue to rely on the statements made herein because one or more sales to the
Transferee may be in reliance on Rule 144A.

         Yes ___    or   No ___   Will the Transferee be purchasing the
                                  Transferred Certificates only for the
                                  Transferee's own account?

6. If the answer to the foregoing question is "no", then in each case where the
Transferee is purchasing for an account other than its own, such account belongs
to a third party that is itself a "qualified institutional buyer" within the
meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been established by the Transferee through one or more of the
appropriate methods contemplated by Rule 144A.

7. The Transferee will notify each of the parties to which this certification is
made of any changes in the information and conclusions herein. Until such notice
is given, the Transferee's purchase of the Transferred Certificates will
constitute a reaffirmation of this certification as of the date of such
purchase. In addition, if the Transferee is a bank or savings and loan as
provided above, the Transferee agrees that it will furnish to such parties any
updated annual financial statements that become available on or before the date
of such purchase, promptly after they become available.

8. Capitalized terms used but not defined herein have the respective meanings
ascribed thereto in the Pooling and Servicing Agreement pursuant to which the
Transferred Certificates were issued.

                                                       ANNEX 2 TO EXHIBIT F-2A

           QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
          [For Transferees That Are Registered Investment Companies]

      The undersigned hereby certifies as follows to [name of Transferor] (the
"Transferor") and [name of Certificate Registrar], as Certificate Registrar,
with respect to the mortgage pass-through certificates (the "Transferred
Certificates") described in the Transferee certificate to which this
certification relates and to which this certification is an Annex:

1. As indicated below, the undersigned is the chief financial officer, a person
fulfilling an equivalent function, or other executive officer of the entity
purchasing the Transferred Certificates (the "Transferee") or, if the Transferee
is a "qualified institutional buyer" as that term is defined in Rule 144A under
the Securities Act of 1933, as amended ("Rule 144A") because the Transferee is
part of a Family of Investment Companies (as defined below), is an executive
officer of the investment adviser (the "Adviser").

2. The Transferee is a "qualified institutional buyer" as defined in Rule 144A
because (i) the Transferee is an investment company registered under the
Investment Company Act of 1940, and (ii) as marked below, the Transferee alone
owned and/or invested on a discretionary basis, or the Transferee's Family of
Investment Companies owned, at least $100,000,000 in securities (other than the
excluded securities referred to below) as of the end of the Transferee's most
recent fiscal year. For purposes of determining the amount of securities owned
by the Transferee or the Transferee's Family of Investment Companies, the cost
of such securities was used, unless the Transferee or any member of the
Transferee's Family of Investment Companies, as the case may be, reports its
securities holdings in its financial statements on the basis of their market
value, and no current information with respect to the cost of those securities
has been published, in which case the securities of such entity were valued at
market.

      ____  The Transferee owned and/or invested on a discretionary basis
            $___________________ in securities (other than the excluded
            securities referred to below) as of the end of the Transferee's most
            recent fiscal year (such amount being calculated in accordance with
            Rule 144A).

      ____  The Transferee is part of a Family of Investment Companies which
            owned in the aggregate $______________ in securities (other than the
            excluded securities referred to below) as of the end of the
            Transferee's most recent fiscal year (such amount being calculated
            in accordance with Rule 144A).

3. The term "Family of Investment Companies" as used herein means two or more
registered investment companies (or series thereof) that have the same
investment adviser or investment advisers that are affiliated (by virtue of
being majority owned subsidiaries of the same parent or because one investment
adviser is a majority owned subsidiary of the other).

4. The term "securities" as used herein does not include (i) securities of
issuers that are affiliated with the Transferee or are part of the Transferee's
Family of Investment Companies, (ii) bank deposit notes and certificates of
deposit, (iii) loan participations, (iv) repurchase agreements, (v) securities
owned but subject to a repurchase agreement and (vi) currency, interest rate and
commodity swaps. For purposes of determining the aggregate amount of securities
owned and/or invested on a discretionary basis by the Transferee, or owned by
the Transferee's Family of Investment Companies, the securities referred to in
this paragraph were excluded.

5. The Transferee is familiar with Rule 144A and understands that the Transferor
and other parties related to the Transferred Certificates are relying and will
continue to rely on the statements made herein because one or more sales to the
Transferee will be in reliance on Rule 144A.

         Yes ___    or   No ___   Will the Transferee be purchasing the
                                  Transferred Certificates only for the
                                  Transferee's own account?

6. If the answer to the foregoing question is "no", then in each case where the
Transferee is purchasing for an account other than its own, such account belongs
to a third party that is itself a "qualified institutional buyer" within the
meaning of Rule 144A, and the "qualified institutional buyer" status of such
third party has been established by the Transferee through one or more of the

and warrants to you, as Certificate Registrar, that:

1. Transferee is acquiring the Transferred Certificates for its own account for
investment and not with a view to or for sale or transfer in connection with any
distribution thereof, in whole or in part, in any manner which would violate the
Securities Act of 1933, as amended (the "Securities Act"), or any applicable
state securities laws.

2. Transferee understands that (a) the Transferred Certificates have not been

3. The Transferee understands that it may not sell or otherwise transfer the

provisions of Section 5.02 of the Pooling and Servicing Agreement, which
provisions it has carefully reviewed, and that the Transferred Certificates will
bear legends substantially to the following effect:

            THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER THE
            SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") OR THE
            SECURITIES LAWS OF ANY STATE. ANY RESALE, PLEDGE, TRANSFER OR OTHER
            DISPOSITION OF THIS CERTIFICATE WITHOUT SUCH REGISTRATION OR
            QUALIFICATION MAY BE MADE ONLY IN A TRANSACTION WHICH DOES NOT
            REQUIRE SUCH REGISTRATION OR QUALIFICATION AND WHICH IS IN
            ACCORDANCE WITH THE PROVISIONS OF SECTION 5.02 OF THE POOLING AND
            SERVICING AGREEMENT REFERRED TO HEREIN.

            NO TRANSFER OF THIS CERTIFICATE OR ANY INTEREST HEREIN MAY BE MADE

            SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986 (THE "CODE"), OR
            (B) TO ANY PERSON WHO IS DIRECTLY OR INDIRECTLY PURCHASING THIS

            OF, AS TRUSTEE OF, OR WITH ASSETS OF ANY SUCH RETIREMENT PLAN OR
            OTHER EMPLOYEE BENEFIT PLAN OR ARRANGEMENT, EXCEPT IN ACCORDANCE

transferred, pledged, sold or otherwise disposed of any Transferred Certificate,
any interest in a Transferred Certificate or any other similar security to any
person in any manner, (b) solicited any offer to buy or accept a transfer,
pledge or other disposition of any Transferred Certificate, any interest in a
Transferred Certificate or any other similar security from any person in any
manner, (c) otherwise approached or negotiated with respect to any Transferred

security with any person in any manner, (d) made any general solicitation by
means of general advertising or in any other manner, or (e) taken any other
action, that (in the case of any of the acts described in clauses (a) through
(e) above) would constitute a distribution of the Transferred Certificates under
the Securities Act, would render the disposition of the Transferred Certificates
a violation of Section 5 of the Securities Act or any state securities law or
would require registration or qualification of the Transferred Certificates
pursuant thereto. The Transferee will not act, nor has it authorized nor will it
authorize any person to act, in any manner set forth in the foregoing sentence
with respect to the Transferred Certificates, any interest in the Transferred
Certificates or any other similar security.

5. The Transferee has been furnished with all information regarding (a) the
Depositor, (b) the Transferred Certificates and distributions thereon, (c)
nature, performance and servicing of the Mortgage Loans, (d) the Pooling and
Servicing Agreement and the Trust Fund created pursuant thereto and (e) all
related matters, that it has requested.

6. The Transferee is an "accredited investor" within the meaning of paragraph
(1), (2), (3) or (7) of Rule 501(a) under the Securities Act or an entity in
which all the equity owners come within such paragraphs and has such knowledge
and experience in financial and business matters as to be capable of evaluating
the merits and risks of an investment in the Transferred Certificates; the
Transferee has sought such accounting, legal and tax advice as it has considered
necessary to make an informed investment decision; and the Transferee is able to
bear the economic risks of such an investment and can afford a complete loss of
such investment.

the name of a nominee, such nominee has completed the Nominee Acknowledgment
below.

                                    Very truly yours,

      The undersigned hereby certifies as follows to [name of Transferor] (the
"Transferor") and for the benefit of Credit Suisse First Boston Mortgage
Securities Corp. with respect to the mortgage pass-through certificates being
transferred in book-entry form (the "Transferred Certificates") as described in
the Transferee Certificate to which this certification relates and to which this
certification is an Annex:

1. As indicated below, the undersigned is the chief financial officer, a person
fulfilling an equivalent function, or other executive officer of the entity
acquiring interests in the Transferred Certificates (the "Transferee").

2. The Transferee is a "qualified institutional buyer" as that term is defined
in Rule 144A under the Securities Act of 1933, as amended ("Rule 144A") because
(i) [the Transferee] [each of the Transferee's equity owners] owned and/or
invested on a discretionary basis $__________________2 in securities (other than

            association, building and loan association, cooperative bank,

            not more than 18 months preceding such date of sale in the case of a
            foreign savings and loan association or equivalent institution.

      ___   Broker-dealer. The Transferee is a dealer registered pursuant to
            Section 15 of the Securities Exchange Act of 1934, as amended.

      ___   Insurance Company. The Transferee is an insurance company whose
            primary and predominant business activity is the writing of
            insurance or the reinsuring of risks underwritten by insurance
            companies and which is subject to supervision by the insurance
            commissioner or a similar official or agency of a State, U.S.
            territory or the District of Columbia.

      ___   State or Local Plan. The Transferee is a plan established and
            maintained by a State, its political subdivisions, or any agency or
            instrumentality of the State or its political subdivisions, for the
            benefit of its employees.

      ___   ERISA Plan. The Transferee is an employee benefit plan within the
            meaning of Title I of the Employee Retirement Income Security Act of
            1974.

      ___   Investment Advisor. The Transferee is an investment advisor
            registered under the Investment Advisers Act of 1940, as amended.

      ___   QIB Subsidiary. All of the Transferee's equity owners are "qualified
            institutional buyers" within the meaning of Rule 144A.

      ___   Other. (Please supply a brief description of the entity and a
            cross-reference to the paragraph and subparagraph under subsection
            (a)(1) of Rule 144A pursuant to which it qualifies. Note that
            registered investment companies should complete Annex 2 rather than
            this Annex 1.)

3. For purposes of determining the aggregate amount of securities owned and/or
invested on a discretionary basis by the Transferee, the Transferee did not
include (i) securities of issuers that are affiliated with such Person, (ii)
securities that are part of an unsold allotment to or subscription by such
Person, if such Person is a dealer, (iii) bank deposit notes and certificates of
deposit, (iv) loan participations, (v) repurchase agreements, (vi) securities
owned but subject to a repurchase agreement and (vii) currency, interest rate
and commodity swaps.

4. For purposes of determining the aggregate amount of securities owned and/or
invested on a discretionary basis by any such Person, the Transferee used the
cost of such securities to such Person, unless such Person reports its
securities holdings in its financial statements on the basis of their market
value, and no current information with respect to the cost of those securities
has been published, in which case the securities were valued at market. Further,
in determining such aggregate amount, the Transferee may have included
securities owned by subsidiaries of such Person, but only if such subsidiaries
are consolidated with such Person in its financial statements prepared in
accordance with generally accepted accounting principles and if the investments
of such subsidiaries are managed under such Person's direction. However, such
securities were not included if such Person is a majority-owned, consolidated
subsidiary of another enterprise and such Person is not itself a reporting
company under the Securities Exchange Act of 1934, as amended.

5. The Transferee acknowledges that it is familiar with Rule 144A and
understands that the Transferor and other parties related to the Transferred
Certificates are relying and will continue to rely on the statements made herein
because one or more Transfers to the Transferee may be in reliance on Rule 144A.

         Yes ___    or   No ___   Will the Transferee be acquiring the
                                  Transferred Certificates only for the
                                  Transferee's own account?

6. If the answer to the foregoing question is "no", then in each case where the
Transferee is acquiring any interest in the Transferred Certificates for an
account other than its own, such account belongs to a third party that is itself
a "qualified institutional buyer" within the meaning of Rule 144A, and the
"qualified institutional buyer" status of such third party has been established
by the Transferee through one or more of the appropriate methods contemplated by
Rule 144A.

7. The Transferee will notify each of the parties to which this certification is
made of any changes in the information and conclusions herein. Until such notice
is given, the Transferee's acquisition of any interest in of the Transferred
Certificates will constitute a reaffirmation of this certification as of the
date of such acquisition. In addition, if the Transferee is a bank or savings
and loan as provided above, the Transferee agrees that it will furnish to such
parties any updated annual financial statements that become available on or
before the date of such acquisition, promptly after they become available.

8. Capitalized terms used but not defined herein have the meanings ascribed
thereto in the Pooling and Servicing Agreement pursuant to which the Transferred
Certificates were issued.

                                                       ANNEX 2 TO EXHIBIT F-2C

           QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A
          [for Transferees that are Registered Investment Companies]

      The undersigned hereby certifies as follows to [name of Transferor] (the
"Transferor") and for the benefit of Credit Suisse First Boston Mortgage
Securities Corp. with respect to the mortgage pass-through certificates being
transferred in book-entry form (the "Transferred Certificates") as described in
the Transferee Certificate to which this certification relates and to which this
certification is an Annex:

1. As indicated below, the undersigned is the chief financial officer, a person
fulfilling an equivalent function, or other executive officer of the entity
acquiring interests in the Transferred Certificates (the "Transferee") or, if
the Transferee is a "qualified institutional buyer" as that term is defined in
Rule 144A under the Securities Act of 1933, as amended ("Rule 144A") because the
Transferee is part of a Family of Investment Companies (as defined below), is an
executive officer of the investment adviser (the "Adviser").

2. The Transferee is a "qualified institutional buyer" as defined in Rule 144A
because (i) the Transferee is an investment company registered under the
Investment Company Act of 1940, as amended, and (ii) as marked below, the
Transferee alone owned and/or invested on a discretionary basis, or the
Transferee's Family of Investment Companies owned, at least $100,000,000 in
securities (other than the excluded securities referred to below) as of the end
of the Transferee's most recent fiscal year. For purposes of determining the
amount of securities owned by the Transferee or the Transferee's Family of
Investment Companies, the cost of such securities was used, unless the
Transferee or any member of the Transferee's Family of Investment Companies, as
the case may be, reports its securities holdings in its financial statements on
the basis of their market value, and no current information with respect to the
cost of those securities has been published, in which case the securities of
such entity were valued at market.

      ____  The Transferee owned and/or invested on a discretionary basis
            $___________________ in securities (other than the excluded
            securities referred to below) as of the end of the Transferee's most
            recent fiscal year (such amount being calculated in accordance with
            Rule 144A).

      ____  The Transferee is part of a Family of Investment Companies which
            owned in the aggregate $______________ in securities (other than the
            excluded securities referred to below) as of the end of the
            Transferee's most recent fiscal year (such amount being calculated
            in accordance with Rule 144A).

3. The term "Family of Investment Companies" as used herein means two or more
registered investment companies (or series thereof) that have the same
investment adviser or investment advisers that are affiliated (by virtue of
being majority owned subsidiaries of the same parent or because one investment
adviser is a majority owned subsidiary of the other).

4. The term "securities" as used herein does not include (i) securities of
issuers that are affiliated with the Transferee or are part of the Transferee's
Family of Investment Companies, (ii) bank deposit notes and certificates of
deposit, (iii) loan participations, (iv) repurchase agreements, (v) securities
owned but subject to a repurchase agreement and (vi) currency, interest rate and
commodity swaps. For purposes of determining the aggregate amount of securities
owned and/or invested on a discretionary basis by the Transferee, or owned by
the Transferee's Family of Investment Companies, the securities referred to in
this paragraph were excluded.

5. The Transferee is familiar with Rule 144A and understands that the Transferor
and other parties related to the Transferred Certificates are relying and will
continue to rely on the statements made herein because one or more Transfers to
the Transferee will be in reliance on Rule 144A.

         Yes ___    or   No ___   Will the Transferee be purchasing the
                                  Transferred Certificates only for the
                                  Transferee's own account?

6. If the answer to the foregoing question is "no", then in each case where the
Transferee is acquiring any interest in the Transferred Certificates for an
account other than its own, such account belongs to a third party that is itself
a "qualified institutional buyer" within the meaning of Rule 144A, and the
"qualified institutional buyer" status of such third party has been established
by the Transferee through one or more of the appropriate methods contemplated by
Rule 144A.

7. The undersigned will notify the parties to which this certification is made
of any changes in the information and conclusions herein. Until such notice, the
Transferee's acquisition of any interest in the Transferred Certificates will
constitute a reaffirmation of this certification by the undersigned as of the
date of such acquisition.

8. Capitalized terms used but not defined herein have the meanings ascribed
thereto in the Pooling and Servicing Agreement pursuant to which the Transferred
Certificates were issued.

Ladies and Gentlemen:

      This letter is delivered to you in connection with the transfer by
____________________ (the "Transferor") to ____________________________ (the
"Transferee") of the Excess Servicing Fee Rights for [the Co-op Mortgage Loans]
[the Mortgage Loans (other than the Co-op Mortgage Loans] (the "Subject Excess
Servicing Fee Rights") established pursuant to the Pooling and Servicing
Agreement, dated as of June 1, 2003 (the "Pooling and Servicing Agreement"),
among Credit Suisse First Boston Mortgage Securities Corp. as depositor, KeyCorp
Real Estate Capital Markets, Inc., as general master servicer (in such capacity,
the "General Master Servicer"), ARCap Servicing, Inc., as general special
servicer (in such capacity, the "General Special Servicer"), NCB, FSB, as NCBFSB

Consumer Cooperative Bank, as co-op special servicer (in such capacity, the
"Co-op Special Servicer") and Wells Fargo Bank Minnesota, N.A., as trustee (in
such capacity, the "Trustee"). All capitalized terms used but not otherwise
defined herein shall have the respective meanings set forth in the Pooling and
Servicing Agreement. The Transferee hereby certifies, represents and warrants to
you, as Depositor and initial applicable Master Servicer, respectively, that:

1. The Transferee is acquiring the Subject Excess Servicing Fee Rights for its
own account for investment and not with a view to or for sale or transfer in
connection with any distribution thereof, in whole or in part, in any manner
which would violate the Securities Act of 1933, as amended (the "Securities
Act"), or any applicable state securities laws.

2. The Transferee understands that (a) the Subject Excess Servicing Fee Rights
have not been and will not be registered under the Securities Act or registered
or qualified under any applicable state securities laws, (b) neither the
Depositor nor the Trustee is obligated so to register or qualify the Subject
Excess Servicing Fee Rights, and (c) the Subject Excess Servicing Fee Rights may
not be resold or transferred unless they are (i) registered pursuant to the
Securities Act and registered or qualified pursuant any applicable state
securities laws or (ii) sold or transferred in transactions which are exempt
from such registration and qualification and (A) the Depositor has received a
certificate from the prospective transferor substantially in the form attached
as Exhibit F-3A to the Pooling and Servicing Agreement, and (B) the applicable
Master Servicer and the Depositor have received a certificate from the
prospective transferee substantially in the form attached as Exhibit F-3B to the
Pooling and Servicing Agreement.

3. The Transferee understands that it may not sell or otherwise transfer the
Subject Excess Servicing Fee Rights or any interest therein except in compliance
with the provisions of Section 3.11 of the Pooling and Servicing Agreement,
which provisions it has carefully reviewed.

4. Neither the Transferee nor anyone acting on its behalf has (a) offered,
pledged, sold, disposed of or otherwise transferred the Subject Excess Servicing
Fee Rights, any interest in the Subject Excess Servicing Fee Rights or any other
similar security to any person in any manner, (b) solicited any offer to buy or
accept a pledge, disposition or other transfer of the Subject Excess Servicing
Fee Rights, any interest in the Subject Excess Servicing Fee Rights or any other
similar security from any person in any manner, (c) otherwise approached or
negotiated with respect to the Subject Excess Servicing Fee Rights, any interest

Subject Excess Servicing Fee Rights, any interest in the Subject Excess
Servicing Fee Rights or any other similar security by means of general
advertising or in any other manner, or (e) taken any other action with respect
to the Subject Excess Servicing Fee Rights, any interest in the Subject Excess
Servicing Fee Rights or any other similar security, which (in the case of any of
the acts described in clauses (a) through (e) above) would constitute a
distribution of the Subject Excess Servicing Fee Rights under the Securities
Act, would render the disposition of the Subject Excess Servicing Fee Rights a
violation of Section 5 of the Securities Act or any state securities law or
would require registration or qualification of the Subject Excess Servicing Fee
Rights pursuant thereto. The Transferee will not act, nor has it authorized or
will it authorize any person to act, in any manner set forth in the foregoing
sentence with respect to the Subject Excess Servicing Fee Rights, any interest
in the Subject Excess Servicing Fee Rights or any other similar security.

5. The Transferee has been furnished with all information regarding (a) the
Depositor, (b) the Subject Excess Servicing Fee Rights and payments thereon, (c)
the Pooling and Servicing Agreement and the Trust Fund created pursuant thereto,
(d) the nature, performance and servicing of the Mortgage Loans, and (e) all
related matters, that it has requested.

6. The Transferee is (a) a "qualified institutional buyer" within the meaning of
Rule 144A under the Securities Act or (b) an "accredited investor" as defined in
any of paragraphs (1), (2), (3) and (7) of Rule 501(a) under the Securities Act
or an entity in which all of the equity owners come within such paragraphs. The
Transferee has such knowledge and experience in financial and business matters
as to be capable of evaluating the merits and risks of an investment in the
Subject Excess Servicing Fee Rights; the Transferee has sought such accounting,
legal and tax advice as it has considered necessary to make an informed
investment decision; and the Transferee is able to bear the economic risks of
such investment and can afford a complete loss of such investment.

7. The Transferee agrees (i) to keep all information relating to the Trust and
the Trust Fund, and made available to it by the applicable Master Servicer,
confidential, (ii) not to use or disclose such information in any manner which
could result in a violation of any provision of the Securities Act or would
require registration of the Subject Excess Servicing Fee Rights or any
Certificates pursuant to the Securities Act, and (iii) not to disclose such
information, and to cause its officers, directors, partners employees, agents or
representatives not to disclose such information, in any manner whatsoever, in
whole or in part, to any other Person other than such holder's auditors, legal
counsel and regulators, except to the extent such disclosure is required by law,
court order or other legal requirement or to the extent such information is of
public knowledge at the time of disclosure by such holder or has become
generally available to the public other than as a result of disclosure by such
holder; provided, however, that such holder may provide all or any part of such
information to any other Person who is contemplating an acquisition of the
Subject Excess Servicing Fee Rights if, and only if, such Person (x) confirms in
writing such prospective acquisition and (y) agrees in writing to keep such
information confidential, not to use or disclose such information in any manner
which could result in a violation of any provision of the Securities Act or
would require registration of the Subject Excess Servicing Fee Rights or any
Certificates pursuant to the Securities Act and not to disclose such
information, and to cause its officers, directors, partners, employees, agents
or representatives not to disclose such information, in any manner whatsoever,
in whole or in part, to any other Person other than such Persons' auditors,
legal counsel and regulators.

8. The Transferee acknowledges that the holder of the Subject Excess Servicing
Fee Rights shall not have any rights under the Pooling and Servicing Agreement
except as set forth in Section 3.11(a) of the Pooling and Servicing Agreement,
and that the Excess Servicing Fee Rate may be reduced to the extent provided in
the Pooling and Servicing Agreement.

                      FOR TRANSFERS OF CLASS R CERTIFICATES

STATE OF                )
                        )  ss.:
COUNTY OF               )




                        ____________________,  being first duly sworn, deposes
and says that:

1. He/She is the ____________________ of ____________________ (the prospective
transferee (the "Transferee") of Credit Suisse First Boston Mortgage Securities
Corp., Commercial Mortgage Pass-Through Certificates, Series 2003-C3, Class R,
evidencing a ___% Percentage Interest in such Class (the "Residual Interest
Certificates")), a _________________ duly organized and validly existing under
the laws of ____________________, on behalf of which he/she makes this
affidavit. All capitalized terms used but not otherwise defined herein shall
have the respective meanings set forth in the Pooling and Servicing Agreement
pursuant to which the Residual Interest Certificates were issued (the "Pooling
and Servicing Agreement").

2. The Transferee (i) is, and as of the date of transfer will be, a "Permitted
Transferee" and will endeavor to remain a "Permitted Transferee" for so long as
it holds the Residual Certificates, and (ii) is acquiring the Residual
Certificates for its own account or for the account of another prospective
transferee from which it has received an affidavit in substantially the same
form as this affidavit. A "Permitted Transferee" is any Person other than a
Disqualified Organization, a possession of the United States, Non-United States
Tax Person or domestic partnership whose beneficial interests are not all held
by United States Person. (For this purpose, a "Disqualified Organization" means
the United States, any state or political subdivision thereof, any agency or
instrumentality of any of the foregoing (other than an instrumentality, all of
the activities of which are subject to tax and, except for the Federal Home Loan
Mortgage Corporation, a majority of whose board of directors is not selected by
any such governmental entity) or any foreign government, international
organization or any agency or instrumentality of such foreign government or
organization, any rural electric or telephone cooperative, or any organization
(other than certain farmers' cooperatives) that is generally exempt from federal
income tax unless such organization is subject to the tax on unrelated business
taxable income).

3. The Transferee is aware (i) of the tax that would be imposed under the Code
on transfers of the Residual Interest Certificates to non-Permitted Transferees;
(ii) that such tax would be on the transferor or, if such transfer is through an
agent (which Person includes a broker, nominee or middleman) for a non-Permitted
Transferee, on the agent; (iii) that the Person otherwise liable for the tax
shall be relieved of liability for the tax if the transferee furnishes to such
Person an affidavit that the transferee is a Permitted Transferee and, at the
time of transfer, such Person does not have actual knowledge that the affidavit
is false; and (iv) that the Residual Interest Certificates may be a "noneconomic
residual interest" within the meaning of Treasury regulation Section 1.860E-1(c)
and that the transferor of a noneconomic residual interest will remain liable
for any taxes due with respect to the income on such residual interest, unless
no significant purpose of the transfer is to enable the transferor to impede the
assessment or collection of tax.

4. The Transferee is aware of the tax imposed on a "pass-through entity" holding
the Residual Interest Certificates if at any time during the taxable year of the
pass-through entity a non-Permitted Transferee is the record holder of an
interest in such entity. (For this purpose, a "pass-through entity" includes a
regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

5. The Transferee is aware that the Certificate Registrar will not register any
transfer of the Residual Interest Certificates by the Transferee unless the
Transferee's transferee, or such transferee's agent, delivers to the Certificate
Registrar, among other things, an affidavit and agreement in substantially the
same form as this affidavit and agreement. The Transferee expressly agrees that
it will not consummate any such transfer if it knows or believes that any
representation contained in such affidavit and agreement is false.

6. The Transferee consents to any additional restrictions or arrangements that
shall be deemed necessary upon advice of counsel to constitute a reasonable
arrangement to ensure that the Residual Interest Certificates will only be
owned, directly or indirectly, by a Permitted Transferee.

7. The Transferee's taxpayer identification number is ___________________.

8. The Transferee has reviewed the provisions of Section 5.02(d) of the Pooling
and Servicing Agreement, a description of which provisions is set forth in the
Residual Interest Certificates (in particular, clause (ii)(A) of Section 5.02(d)
which authorizes the Trustee to deliver payments on the Residual Interest
Certificates to a Person other than the Transferee and clause (ii)(B) of Section
5.02(d) which authorizes the Trustee to negotiate a mandatory sale of the
Residual Interest Certificates, in either case, in the event that the Transferee
holds such Residual Interest Certificates in violation of Section 5.02(d)); and
the Transferee expressly agrees to be bound by and to comply with such
provisions.

9. The Transferee will not cause income from the Residual Interest Certificate
to be attributable to a foreign permanent establishment or fixed base, within
the meaning of an applicable income tax treaty, of the Transferee or any other
U.S. Person.

10. No purpose of the Transferee relating to its purchase or any sale of the
Residual Certificates is or will be to impede the assessment or collection of
any tax and (check the one that applies):

          [ ] The present value of the anticipated tax liabilities associated
with holding the Residual Interest Certificate does not exceed the sum of:

            (i)   the present value of any consideration given to the Transferee
                  to acquire such Residual Interest Certificate;

            (ii)  the present value of the expected future distributions on such
                  Residual Interest Certificate; and

            (iii) the present value of the anticipated tax savings associated
                  with holding such Residual Interest Certificate as the related
                  REMIC generates losses.

            For purposes of this calculation, (i) the Transferee is assumed to
pay tax at the highest rate currently specified in Section 11(b) of the Code
(but the tax rate in Section 55(b)(1)(B) of the Code may be used in lieu of the
highest rate specified in Section 11(b) of the Code if the Transferee has been
subject to the alternative minimum tax under Section 55 of the Code in the
preceding two years and will compute its taxable income in the current taxable
year using the alternative minimum tax rate) and (ii) present values are
computed using a discount rate equal to the short-term Federal rate prescribed
by Section 1274(d) of the Code for the month of the transfer and the compounding
period used by the Transferee.

          [ ] The transfer of the Residual Interest Certificate complies with
U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

            (i)   the Transferee is an "eligible corporation," as defined in
                  U.S. Treasury Regulations Section 1.860E-1(c)(6)(i), as to
                  which income from the Residual Interest Certificate will only
                  be taxed in the United States;

            (ii)  at the time of the transfer, and at the close of the
                  Transferee's two fiscal years preceding the year of the
                  transfer, the Transferee had gross assets for financial
                  reporting purposes (excluding any obligation of a person
                  related to the Transferee within the meaning of U.S. Treasury
                  Regulations Section 1.860E-1(c)(6)(ii)) in excess of $100
                  million and net assets in excess of $10 million;

            (iii) the Transferee will transfer the Residual Interest Certificate
                  only to another "eligible corporation," as defined in U.S.
                  Treasury Regulations Section 1.860E-1(c)(6)(i), in a
                  transaction that satisfies the requirements of Sections
                  1.860E-1(c)(4)(i), (ii) and (iii) and Section 1.860E-1(c)(5)
                  of the U.S. Treasury Regulations; and

            (iv)  the Transferee determined the consideration paid to it to
                  acquire the Residual Interest Certificate based on reasonable
                  market assumptions (including, but not limited to, borrowing
                  and investment rates, prepayment and loss assumptions, expense
                  and reinvestment assumptions, tax rates and other factors
                  specific to the Transferee) that it has determined in good
                  faith.

          [ ]     None of the above.

11. The Transferee hereby represents to and for the benefit of the transferor
that the Transferee intends to pay any taxes associated with holding the
Residual Certificates as they become due, fully understanding that it may incur
tax liabilities in excess of any cash flows generated by the Residual
Certificates.

12. The Transferee is a citizen or resident of the United States, a corporation,
partnership or other entity created or organized in, or under the laws of, the
United States, State thereof and the District of Columbia, an estate whose
income from sources without the United States is includible in gross income for
United States federal income tax purposes regardless of its connection with the
conduct of a trade or business within the United States or a trust as to which
(i) a court in the United States is able to exercise primary supervision over
the administration of the trust and (ii) one or more United States fiduciaries
have the right to control all substantial decisions of the trust.

Ladies and Gentlemen:

      This letter is delivered to you in connection with the transfer by
_________________ (the "Transferor") to _________________ (the "Transferee") of
the Residual Interest Certificates, pursuant to the Pooling and Servicing
Agreement dated as of June 1, 2003 (the "Pooling and Servicing Agreement"),
among Credit Suisse First Boston Mortgage Securities Corp. as depositor, KeyCorp
Real Estate Capital Markets, Inc., as general master servicer (in such capacity,
the "General Master Servicer"), ARCap Servicing, Inc., as general special
servicer (in such capacity, the "General Special Servicer"), NCB, FSB, as NCBFSB
master servicer (in such capacity, the "NCBFSB Master Servicer"), National
Consumer Cooperative Bank, as co-op special servicer (in such capacity, the
"Co-op Special Servicer") and Wells Fargo Bank Minnesota, N.A., as trustee (in
such capacity, the "Trustee"). All capitalized terms used but not otherwise
defined herein shall have the respective meanings set forth in the Pooling and
Servicing Agreement. The Transferor hereby certifies, represents and warrants to
you, as Certificate Registrar, that:

1. No purpose of the Transferor relating to the transfer of the Residual
Interest Certificates by the Transferor to the Transferee is or will be to
impede the assessment or collection of any tax.

2. The Transferor understands that the Transferee has delivered to you a
Transfer Affidavit and Agreement in the form attached to the Pooling and
Servicing Agreement as Exhibit H-1. The Transferor does not know or believe that
any representation contained therein is false.

3. The Transferor has at the time of this transfer conducted a reasonable
investigation of the financial condition of the Transferee (or the beneficial
owners of the Transferee if the Transferee is classified as a partnership under
the Code) as contemplated by Treasury regulation Section 1.860E-1(c)(4)(i) and,
as a result of that investigation, the Transferor has determined that the
Transferee has historically paid its debts as they became due and has found no
significant evidence to indicate that the Transferee will not continue to pay
its debts as they become due in the future. The Transferor understands that the
transfer of the Residual Interest Certificates may not be respected for United
States income tax purposes (and the Transferor may continue to be liable for
United States income taxes associated therewith) unless the Transferor has

         FORM OF SUBORDINATION AGREEMENT FOR NCB FSB SUBORDINATE DEBT

            THIS Agreement made this _____ day of ___, 20__, between [_______],
a ____________ having an address at __________ (the "Subordinate Mortgagee"),
and ___________, a ___________, having an office at ____________ (the "Superior
Mortgagee").

                             W I T N E S S E T H:

            WHEREAS, Superior Mortgagee is the owner of a certain $__________
mortgage and note secured thereby, dated ________ __, ____, made by
__________________________________ (the "Borrower") to Subordinate Mortgagee
(the "Superior Mortgage") covering the premises located at
____________________________________________ more particularly described in the
Superior Mortgage and Schedule "A" attached hereto (the "Premises"); and

            WHEREAS, Subordinate Mortgagee is the holder of a certain
$____________ mortgage and the note secured thereby, dated ________ __, ____,
made by the Borrower to Subordinate Mortgagee (the "Subordinate Mortgage")
covering the Premises; and

            WHEREAS, the Superior Mortgagee has purchased the Superior Mortgage
from Subordinate Mortgagee and as a condition thereto has required that the
Subordinate Mortgage be fully subordinated to the Superior Mortgage.

            NOW, THEREFORE, the parties hereto agree as follows:

            The Subordinate Mortgagee hereby covenants and agrees that (i) the
Subordinate Mortgage and all of its terms and provisions and the loan it secures
are and shall remain in all respects subject and subordinate to the Superior
Mortgage, its lien and all of its terms and provisions and to the loan it
secures and to any modifications, consolidations, extension or renewals thereof
and to any increases therein resulting from advances to protect or preserve the
lien of the Superior Mortgage on the Premises encumbered thereby but not any
other increases therein; (ii) no tenant under any lease of any portion of the
Premises, other than tenant shareholders under proprietary leases, will be made
a party defendant in any foreclosure of the Subordinate Mortgage, nor will any
other action be taken in connection with such foreclosure which would have the
effect of terminating any such lease; (iii) no portion of the accounts, accounts
receivable, rents, issues and profits of the Premises shall be collected in
connection with the foreclosure of the Subordinate Mortgage or any other
enforcement action except through a receiver appointed by the court in which
such foreclosure action is brought, after due notice of the application of the
appointment of such receiver shall have been given to the Superior Mortgagee;
(iv) the accounts, accounts receivable, rents, issues and profits collected by
any such receiver (or which shall under any circumstances come into possession
of the holder of the Subordinate Mortgage at a time when Subordinate Mortgagee
has received written notice of a default under the Superior Mortgage) shall be
applied, at Superior Mortgagee's direction, to the payment of taxes, maintenance
and operating charges and disbursements incurred in connection with the
operation and maintenance of the Premises and to the payment of principal,
interest and other amounts due under the Superior Mortgage at the time of such
application, in such order and priority as Superior Mortgagee shall direct,
before any portion of such accounts, accounts receivable, rents, issues and
profits shall be applied to the Subordinate Mortgage; (v) during the pendency of
any such foreclosure action, if an action shall be brought for the foreclosure
of the Superior Mortgage and an application shall be made for an extension of
such receivership for the benefit of the Superior Mortgagee, the Subordinate
Mortgagee shall consent to the extension of such receivership and all accounts,
accounts receivable, rents, issues and profits held by such receiver as of the
date of such application shall be applied by the receiver solely for the benefit
of the Superior Mortgagee, and the Subordinate Mortgagee in their respective
order of priority; (vi) due notice of the commencement of any foreclosure of the
Subordinate Mortgage shall be given to the Superior Mortgagee and true copies of
all papers served or entered in such action will be delivered to the Superior
Mortgagee upon such service or entry; (vii) no payments shall be made to the
holder of the Subordinate Mortgage during the period in which any default exists
under the Superior Mortgage in respect of any monthly payment or balloon payment
due thereunder beyond any applicable grace period, provided that the Subordinate
Mortgagee has received written notice of such default and all payments otherwise
payable to the Subordinate Mortgagee during such period shall be paid to the
Superior Mortgagee and, if any such payments are received by the Subordinate
Mortgagee at any time after which the Subordinate Mortgagee has received written
notice of the existence of such default, they shall be held in trust for the
Superior Mortgagee and turned over to the Superior Mortgagee on demand; (viii)
any distributions made or to be made to the Subordinate Mortgagee pursuant to
any bankruptcy or insolvency proceeding of the borrower representing amounts due
under the Superior Mortgage shall be paid by the borrower, or, if such payments
are nonetheless received by the Subordinate Mortgagee, by the Subordinate
Mortgagee immediately upon their receipt, to the Superior Mortgagee for
application, at Superior Mortgagee's direction, to the payment of principal,
interest and other amounts due under the Superior Mortgage at the time of such
application, in such order and priority as Superior Mortgagee shall direct,
before any portion of such accounts, accounts receivable, rents, issues and
profits shall be applied to the Subordinate Mortgage; and (ix) all condemnation,
casualty or similar payments with respect to the premises shall be applied, for
so long as the Superior Mortgage remains outstanding, in accordance with the
Superior Mortgage.

            This Agreement is governed by and is to be construed under the laws
of the state in which the Premises is located.

            So long as the Superior Mortgage shall remain a lien upon the
Premises or any part thereof, Subordinate Mortgagee shall execute, acknowledge
and deliver, upon Superior Mortgagee's reasonable demand, at any time or from
time to time, any and all further subordinations, agreements or other
instruments in recordable form (and in form reasonably satisfactory to
Subordinate Mortgagee) as Superior Mortgagee may reasonably require for carrying
out the purpose and intent of the covenants contained herein; provided, however,
that no such subordinations, agreements or other instruments shall increase
Subordinate Mortgagee's obligations or decrease Subordinate Mortgagee's rights
under this Agreement or the Subordinate Mortgage.

            So long as the Superior Mortgage shall remain a lien upon the
Premises or any part thereof, Subordinate Mortgagee shall not enter into any
agreement to amend or modify the Subordinate Mortgage in a manner material to
Superior Mortgagee without notice to, and the prior consent of, Superior
Mortgagee.

            In order to enable Superior Mortgagee to enforce any claims by the
Subordinate Mortgagee against the Borrower in any liquidation or dissolution of
Borrower, or any execution sale, receivership, insolvency, bankruptcy,
liquidation, readjustment, reorganization, or other similar proceeding relative
to the Borrower or its property, for so long as the Superior Mortgage shall
remain outstanding, Superior Mortgagee is hereby irrevocably authorized and
empowered in its discretion to make and present, for and on behalf of the
undersigned Subordinate Mortgagee, such proofs of claims against the Borrower on
account of the Subordinate Mortgage as Superior Mortgagee may deem expedient or
proper, and to vote such proofs of claims in any such proceeding and to receive
and collect any and all dividends or other payments or disbursements made
thereon in whatever form the same may be paid or issued. Subordinate Mortgagee
further agrees to execute and deliver to Superior Mortgagee such assignments or
other instruments as may be reasonably required by Superior Mortgagee (and in
form reasonably satisfactory to Subordinate Mortgagee) in order to enable
Superior Mortgagee to enforce any and all such claims and to collect any and all
such payments or disbursements provided, however, that no such assignments or
other instruments shall increase Subordinate Mortgagee's obligations or decrease
Subordinate Mortgagee's rights under this Agreement or the Subordinate Mortgage.

            This Agreement shall not be amended or modified except by an
agreement in writing, signed by the party against whom enforcement is sought.

            Except for notices in a foreclosure action, which shall be given as
provided by applicable rule of court, all notices hereunder shall be given to
each party in the same manner as provided in its mortgage or, if there are no
such notice provisions, at the address set forth above by personal delivery or
first class, certified mail, return receipt requested. Notices shall be deemed
to have been given when received. Either party may change its address for
notices hereunder by written notice to the other party.

            This Agreement shall be binding upon the parties hereto and their
respective heirs, successors and assigns. Any assignee of the Subordinate
Mortgage shall be deemed by acceptance thereof to have assumed the obligations
of Subordinate Mortgagee hereunder. Subordinate Mortgagee hereby agrees to have
such assignee execute a formal assumption agreement upon such assignment but no
failure of an assignee to execute an assumption agreement shall affect such
assignee's assumption of the obligations of the Subordinate Mortgagee.

            Capitalized  terms used but not defined  herein have the  meanings
assigned to such terms in the  Pooling and  Servicing  Agreement.  [Note:  all
terms in this  notice  should be  conformed  to terms used in the  Pooling and
Servicing Agreement]

THE STATEMENTS SET FORTH BELOW ARE MADE (A) TO THE BEST KNOWLEDGE OF THE
UNDERSIGNED BASED UPON DUE DILIGENCE CONSISTENT WITH THE SERVICING STANDARD
SPECIFIED IN THE POOLING AND SERVICING AGREEMENT (THE "SERVICING STANDARD"), AND
(B) WITHOUT INTENDING TO WARRANT THE ACCURACY THEREOF OR UNDERTAKE ANY DUTY OR
STANDARD OF CARE GREATER THAN THE DUTIES OF SERVICER UNDER THE POOLING AND
SERVICING AGREEMENT AND THE SERVICING STANDARD

            We hereby notify you and confirm that each of the following is true,
subject to those exceptions, if any, set forth on Exhibit A hereto, which
exceptions the Servicer has determined, consistent with the Servicing Standard,
will have no material adverse effect on the Mortgage Loan or the defeasance
transaction:

          1.   The Mortgagor has consummated a defeasance of the Mortgage Loan
               of the type checked below:

               ____ a full defeasance of the entire outstanding principal
                    balance ($___________) of the Mortgage Loan; or

               ____ a partial defeasance of a portion ($__________) of the
                    Mortgage Loan that represents ___% of the entire principal
                    balance of the Mortgage Loan ($________);

          2.   The defeasance was consummated on __________, 20__.

          3.   The defeasance was completed in all material respects in
               accordance with the conditions for defeasance specified in the
               Mortgage Loan Documents and in accordance with the Servicing
               Standard.

          4.   The defeasance collateral consists only of one or more of the
               following: (i) direct debt obligations of the U.S. Treasury, (ii)
               direct debt obligations of the Federal National Mortgage
               Association, (iii) direct debt obligations of the Federal Home
               Loan Mortgage Corporation, or (iv) interest-only direct debt
               obligations of the Resolution Funding Corporation. Such
               defeasance collateral consists of securities that (i) if they
               include a principal obligation, the principal due at maturity
               cannot vary or change, (ii) provide for interest at a fixed rate
               and (iii) are not subject to prepayment, call or early
               redemption.

          5.   After the defeasance, the defeasance collateral will be owned by
               an entity (the "Defeasance Obligor") that: (i) is the original
               Borrower, (ii) is a Single-Purpose Entity (as defined in the S&P
               Criteria), (iii) is subject to restrictions in its organizational
               documents substantially similar to those contained in the
               organizational documents of the original Borrower with respect to
               bankruptcy remoteness and single purpose, (iv) has been
               designated as the Defeasance Obligor by the originator of the
               Mortgage Loan pursuant to the terms of the Mortgage Loan
               Documents, or (v) has delivered a letter from Standard & Poor's
               confirming that the organizational documents of such Defeasance
               Obligor were previously approved by Standard & Poor's. The
               Defeasance Obligor owns no assets other than defeasance
               collateral and (only in the case of the original Borrower) real
               property securing one or more Mortgage Loans included in the pool
               under the Pooling and Servicing Agreement (the "Pool").

          6.   If such Defeasance Obligor (together with its affiliates) holds
               more than one defeased loan, it does not (together with its
               affiliates) hold defeased loans aggregating more than $20 Million
               or more than five percent (5%) of the aggregate certificate
               balance of the Certificates as of the date of the most recent
               Paying Agent's Monthly Certificateholder Report received by
               Servicer (the "Current Report").

          7.   The defeasance documents require that the defeasance collateral
               be credited to an eligible account (as defined in the S&P
               Criteria) that must be maintained as a securities account by a
               securities intermediary that is at all times an Eligible
               Institution (as defined in the S&P Criteria). The securities
               intermediary may reinvest proceeds of the defeasance collateral
               only in Permitted Investments (as defined in the Pooling and
               Servicing Agreement).

          8.   The securities intermediary is obligated to pay from the proceeds
               of the defeasance collateral, directly to the Servicer's
               collection account, all scheduled payments on the Mortgage Loan
               or, in a partial defeasance, not less than 125% of the portion of
               such scheduled payments attributed to the allocated loan amount
               for the real property defeased (the "Scheduled Payments").

          9.   The Servicer received written confirmation from an independent
               certified public accountant stating that (i) revenues from the
               defeasance collateral (without taking into account any earnings
               on reinvestment of such revenues) will be sufficient to timely
               pay each of the Scheduled Payments including the payment in full
               of the Mortgage Loan (or the allocated portion thereof in
               connection with a partial defeasance) on its Maturity Date (or,
               in the case of an ARD Loan, on its Anticipated Repayment Date),
               (ii) the revenues received in any month from the defeasance
               collateral will be applied to make Scheduled Payments within four
               (4) months after the date of receipt, (iii) the defeasance
               collateral is not subject to prepayment, call or early
               redemption, and (iv) interest income from the defeasance
               collateral to the Defeasance Obligor in any tax year will not
               exceed such Defeasance Obligor's interest expense for the
               Mortgage Loan (or the allocated portion thereof in a partial
               defeasance) for such year, other than in the year in which the
               Maturity Date or Anticipated Repayment Date will occur, when
               interest income will exceed interest expense.

          10.  The Servicer received opinions of counsel that, subject to
               customary qualifications, (i) the defeasance will not cause the
               Trust to fail to qualify as a REMIC for purpose of the Internal
               Revenue Code, (ii) the agreements executed by the Mortgagor and
               the Defeasance Obligor in connection with the defeasance are
               enforceable against them in accordance with their terms, and
               (iii) the Trustee will have a perfected, first priority security
               interest in the defeasance collateral.

          11.  The agreements executed in connection with the defeasance (i)
               prohibit subordinate liens against the defeasance collateral,
               (ii) provide for payment from sources other than the defeasance
               collateral of all fees and expenses of the securities
               intermediary for administering the defeasance and the securities
               account and all fees and expenses of maintaining the existence of
               the Defeasance Obligor, (iii) permit release of surplus
               defeasance collateral and earnings on reinvestment to the
               Defeasance Obligor only after the Mortgage Loan has been paid in
               full, (iv) include representations and/or covenants of the
               Mortgagor and/or securities intermediary substantially as set
               forth on Exhibit B hereto, (v) provide for survival of such
               representations; and (vi) do not permit waiver of such
               representations and covenants.

          12.  The outstanding principal balance of the Mortgage Loan
               immediately before the defeasance was less than $20,000,000 and
               less than 5% of the aggregate certificate balance of the
               Certificates as of the date of the current Report. The Mortgage
               Loan is not one of the ten (10) largest loans in the pool.

          13.  Copies of all material agreements, instruments, organizational
               documents, opinions of counsel, accountant's report and other
               items delivered in connection with the defeasance will be
               provided to you upon request.

          14.  The individual executing this notice is an authorized officer or
               a servicing officer of the Servicer.

            IN WITNESS WHEREOF, the Servicer has caused this notice to be
executed as of the date captioned above.
