Loan to, but not including, the date of receipt by or on behalf of the Trust
(or, in the case of a full Monthly Payment from any Borrower, through the

interest that constitutes Default Interest or, in the case of the Ritz-Carlton
Key Biscayne Pooled Mortgage Loan, that constitutes RCKB Extra Interest or, in
the case of a Pooled ARD Mortgage Loan after its Anticipated Repayment Date,
that constitutes Post-ARD Additional Interest; third, as a recovery of principal

Biscayne Pooled Mortgage Loan, other than RCKB Extra Interest; tenth, as a
recovery of any remaining principal of such Pooled Mortgage Loan to the extent
of its entire remaining unpaid principal balance; and, eleventh, in the case of

of accrued and unpaid Post-ARD Additional Interest on such Pooled ARD Mortgage
Loan to but not including the date of receipt by or on behalf of the Trust and,
in the case of the Ritz-Carlton Key Biscayne Pooled Mortgage Loan, as a recovery
of any accrued and unpaid RCKB Extra Interest on such Pooled Mortgage Loan to
but not including the date of receipt by or on behalf of the Trust; provided
that any payment of the Additional Sully Place Yield Maintenance Amount in
connection with the repurchase of the Sully Place Pooled Mortgage Loan as a
result of an Early Defeasance with respect thereto shall be applied to such

the

                                      -80-

<PAGE>

Trust, exclusive, however, of any portion of such accrued and unpaid interest
that constitutes Default Interest or, in the case of the Ritz-Carlton Key
Biscayne Pooled Mortgage Loan, that constitutes RCKB Extra Interest or, in the
case of a Pooled REO Loan that relates to a Pooled ARD Mortgage Loan after its
Anticipated Repayment Date, that constitutes Post-ARD Additional Interest;
third, as a recovery of principal of the related Pooled REO Loan to the extent
of its entire unpaid principal balance; fourth, as a recovery of any Prepayment
Premium or Yield Maintenance Charge deemed to be due and owing in respect of the
related Pooled REO Loan; fifth, as a recovery of any Default Charges deemed to
be due and owing in respect of the related Pooled REO Loan; sixth, as a recovery
of any other amounts deemed to be due and owing in respect of the related Pooled
REO Loan (other than, in the case of a Pooled REO Loan that relates to a Pooled
Mortgage Loan after its Anticipated Repayment Date, accrued and unpaid Post-ARD
Additional Interest and, in the case of a Pooled REO Loan that relates to the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan, other than RCKB Extra Interest);
and seventh, in the case of a Pooled REO Loan that relates to a Pooled Mortgage
Loan after its Anticipated Repayment Date, as a recovery of any accrued and

to but not including the date of receipt by or on behalf of the Trust.
Collections allocable to a successor REO Loan in respect of the Great Lakes
Crossing Companion Mortgage Loan shall be applied in the same manner as is
provided in the prior sentence with respect to a successor REO Loan in respect
of the Great Lakes Crossing Pooled Mortgage Loan.

          (c) For the purposes of this Agreement, Post-ARD Additional Interest
on an ARD Mortgage Loan or, if applicable, a successor REO Loan shall be deemed
not to constitute principal or any portion thereof and shall not be added to the
unpaid principal balance or Stated Principal Balance of such ARD Mortgage Loan
or successor REO 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.

          (d) Insofar as amounts received in respect of any Pooled Mortgage
Loan, the Great Lakes Crossing Companion Mortgage Loan or any REO Property and
allocable to shared fees and shared charges owing in respect of such Mortgage
Loan or the related REO Loan(s), as the case may be, that constitute Additional
Master Servicing Compensation payable to the Master Servicer and/or Additional
Special Servicing Compensation payable to the Special Servicer, are insufficient
to cover the full amount of such fees and charges, such amounts shall be
allocated between such of those fees and charges as are payable to the Master
Servicer, on the one hand, and such of those fees and charges as are payable to
the Special Servicer, on the other, pro rata in accordance with their respective
entitlements.

          (e) The foregoing applications of amounts received in respect of any
Mortgage Loan or REO Property shall be determined by the Master Servicer and
reflected in the appropriate monthly report from the Master Servicer and in the
appropriate monthly Trustee Report as provided in Section 4.02.

          SECTION 1.04. Cross-Collateralized Pooled Mortgage Loans.

          Notwithstanding anything herein to the contrary, it is hereby
acknowledged that the groups of Pooled Mortgage Loans identified on the Pooled
Mortgage Loan Schedule as being cross-collateralized with each other are, in the
case of each such particular group of Pooled Mortgage Loans,

                                      -81-

<PAGE>

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 Master Servicer and/or the Special
Servicer, with respect to any Cross-Collateralized Pooled Mortgage Loan (or
successor Pooled REO Loan with respect thereto), the Mortgaged Property (or REO
Property) that relates or corresponds thereto shall be the property identified
in the Pooled 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 Pooled Mortgage Loans in such Cross-Collateralized Group, then
the inclusion of the original of such document in the Mortgage File for any of
the Pooled Mortgage Loans constituting such Cross-Collateralized Group shall be
deemed an inclusion of such original in the Mortgage File for each such Pooled
Mortgage Loan.

                                   ARTICLE II

            CONVEYANCE OF POOLED MORTGAGE LOANS; REPRESENTATIONS AND
                WARRANTIES; ORIGINAL ISSUANCE OF THE CERTIFICATES
                           AND VARIOUS REMIC INTERESTS

          SECTION 2.01. Conveyance of Pooled Mortgage Loans.

          (a) It is the intention of the parties hereto that a common law trust
be established pursuant to this Agreement and, further, that such trust be
designated as "CSFB Commercial Mortgage Trust 2003-CK2". 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 Pooled Mortgage
Loans, all payments under and proceeds of such Pooled 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 Pooled Mortgage Loans
in April 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 Pooled Mortgage Loan; (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 GLCTML Custodial Account (insofar as those funds and/or assets relate to the
Great Lakes Crossing Pooled Mortgage Loan) and, if established, the REO Account,
each A/B Mortgage Loan Pair Custodial Account (insofar as those funds and/or
assets relate to the subject Pooled A-Note Mortgage Loan), each Purchase Price
Security Deposit Account and/or each Special Reserve 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 Pooled Mortgage Loans pursuant to the Designated Sub-Servicer
Agreements.

          Upon the sale of Certificates representing at least 10% of the
aggregate fair value of all the Certificates to parties that are not Affiliates
of the Depositor, the Depositor shall, under GAAP, report: (i) its acquisition
of the Original Pooled Column Mortgage Loans from Column, pursuant to the First
Mortgage Loan Purchase Agreement, as a purchase of such Pooled Mortgage Loans
from Column; (ii) its acquisition of the Original Pooled KeyBank Mortgage Loans
from Column, pursuant to the Second Mortgage Loan Purchase Agreement, as a
purchase of such Pooled Mortgage Loans from Column; and (iii) its transfer of
the Original Pooled Mortgage Loans to the Trustee, pursuant to this Section
2.01(b), as a sale of such Pooled Mortgage Loans to the Trustee. In connection
with the foregoing, upon the sale of Certificates representing at least 10% of
the aggregate fair value of all the Certificates to parties that are not
Affiliates of the Depositor, the Depositor shall cause all of its financial and
accounting records to reflect such acquisitions as purchases and such transfer
as a sale (in each case, as opposed to a secured loan). Regardless of its
treatment of the transfer of the Original Pooled Mortgage Loans to the Trust
under GAAP, the Depositor shall at all times following the Closing Date

                                      -83-

<PAGE>

cause all of its records and financial statements and any relevant consolidated
financial statements of any direct or indirect parent to clearly reflect that
the Original Pooled 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 Pooled 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 such Pooled Mortgage
Loans.

          (c) The conveyance of the Original Pooled 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 Pooled 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 Pooled Mortgage Loans
subject hereto from time to time, all principal and interest received on or with
respect to such Pooled Mortgage Loans after the Closing Date (other than
scheduled payments of interest and principal due and payable on such Pooled
Mortgage Loans on or prior to the related Due Date in April 2003 or, in the case
of a Replacement Pooled Mortgage Loan, on or prior to the related date of
substitution), all amounts held from time to time in the Collection Account, the
Distribution Account, the Interest Reserve Account, the Excess Liquidation
Proceeds Account, the GLCTML Custodial Account (insofar as those amounts relate
to the Great Lakes Crossing Pooled Mortgage Loan) and, if established, the REO
Account, each A/B Mortgage Loan Pair Custodial Account (insofar as those amounts
relate to the subject Pooled A-Note Mortgage Loan), each Purchase Price Security
Deposit Account and/or each Special Reserve Account and all reinvestment
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 Pooled 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 UCC Financing Statement substantially
in the form attached as Exhibit O hereto in all appropriate locations in the
State of Delaware promptly following the initial issuance of the Certificates,
and the Master Servicer shall prepare and file at each such office, and the
Trustee shall execute, continuation statements with respect thereto, in each
case within six months prior to the fifth anniversary of the immediately
preceding filing. The Depositor hereby authorizes the Trustee and the 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 Servicer 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.

                                      -84-

<PAGE>

          (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 of Column, with respect to the Original Pooled
Column Mortgage Loans, and KeyBank, with respect to the Original Pooled KeyBank
Mortgage Loans, at each such party's expense, pursuant to the respective
Mortgage Loan Purchase Agreements, 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 Pooled Mortgage Loan
acquired by the Depositor. In addition, with respect to each Pooled 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 Column, with respect to the Original Pooled Column
Mortgage Loans, and KeyBank, with respect to the Original Pooled KeyBank
Mortgage Loans, 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, and/or to
re-issue, to the Trustee such party's rights as the beneficiary thereof and
drawing party thereunder. The Trustee hereby acknowledges that the assignment
and/or re-issue process will require Column, with respect to the Original Pooled
Column Mortgage Loans, and KeyBank, with respect to the Original Pooled KeyBank
Mortgage Loans, to deliver each original Letter of Credit to the issuing entity
and the Trustee hereby agrees that Column and KeyBank each have up to forty-five
(45) days to complete each such assignment and/or re-issue; provided, however,
that if the Master Servicer determines to make a draw under any such Letter of
Credit before the assignment and/or re-issue has been completed, then Column or
KeyBank, as applicable, will cooperate with the Master Servicer in making the
presentation and draw on the Letter of Credit and, if necessary, shall make such
presentation and draw in its own name pursuant to the written instructions of
the Master Servicer and shall deliver the proceeds thereof to the Master
Servicer for the benefit of the Trust. If such a draw is not honored as a result
of the assignment and/or re-issue process being incomplete, then Column, with
respect to an Original Pooled Column Mortgage Loan, and KeyBank, with respect to
an Original Pooled KeyBank Mortgage Loan, shall be liable to the Trust for all
expenses, damages or losses, including, but not limited to, reimbursement of
interest charged by the Master Servicer for any Advance made in lieu of the such
draw, up to an amount not to exceed the amount of such draw, plus Advance
Interest, and related expenses resulting from the failure of the draw to be so
honored. 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.

          (e) As soon as reasonably possible, and in any event within 60 days
after the later of (i) the Closing Date (or, in the case of a Replacement Pooled
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 (iv) and (v)
of the definition of "Mortgage File" that has been received by the Trustee or a
Custodian on its behalf and each UCC Financing Statement Assignment in favor of
the Trustee referred to in clause (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 Financing Statement
Assignment shall reflect that the filed copy thereof or an appropriate receipt
therefor, as applicable, should be returned to the Trustee following filing;

                                      -85-

<PAGE>

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 or verifications of electronic filing have been returned to the
Trustee, the Trustee shall forward a copy thereof to the 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 Column, with
respect to an Original Pooled Column Mortgage Loan, and KeyBank, with respect to
an Original Pooled KeyBank Mortgage Loan, to prepare or cause to be prepared
promptly, pursuant to the applicable 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 Column or KeyBank has been so notified and has not
prepared a substitute document or cured such defect, as the case may be, within
45 days, the Trustee shall promptly notify the Master Servicer, the Special
Servicer, the Rating Agencies and the Controlling Class Representative.

          The Depositor hereby represents and warrants that it has contractually
obligated Column, with respect to the Original Pooled Column Mortgage Loans, and
KeyBank, with respect to the Original Pooled KeyBank Mortgage Loans, pursuant to
the respective Mortgage Loan Purchase Agreements, to pay the reasonable fees and
out-of-pocket expenses of the Trustee in connection with the above-referenced
recording and filing of assignments and instruments of transfer insofar as they
relate to the Original Pooled Mortgage Loans acquired by the Depositor, all as
more particularly provided for in the respective Mortgage Loan Purchase
Agreements; provided that neither Column nor KeyBank shall be responsible for
actually recording or filing any such assignment or instrument of transfer. In
addition, the Depositor hereby further represents and warrants that it has
contractually obligated Column, with respect to the Original Pooled Column
Mortgage Loans, and KeyBank, with respect to the Original Pooled KeyBank
Mortgage Loans, pursuant to the respective Mortgage Loan Purchase Agreements, to
provide the Trustee with a power of attorney to enable the Trustee to record any
loan documents required to be recorded pursuant to this Section 2.01(e), that
the Trustee has been unable to record.

          (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 Column, with respect to the Original Pooled Column
Mortgage Loans, and KeyBank, with respect to the Original Pooled KeyBank
Mortgage Loans, at each such party's expense, pursuant to the respective
Mortgage Loan Purchase Agreements, to deliver to and deposit with, or cause to
be delivered to and deposited with, the Master Servicer, on or before the
Closing Date, the following items (except to the extent that any of the
following items are to be retained by a Sub-Servicer that will continue to act
on behalf of the Master Servicer): (i) originals or copies of all financial
statements, appraisals, environmental/engineering reports, leases, rent rolls,
third-party underwriting reports, insurance policies, legal opinions, tenant
estoppels and any other relevant documents that the Master Servicer or Special
Servicer reasonably deems necessary to service the respective Pooled Mortgage
Loans in the possession or under the control of Column, with respect to the
Original Pooled Column Mortgage Loans, and KeyBank, with respect to the Original
Pooled KeyBank Mortgage Loans, and, to the extent they are not required to be a
part of a Mortgage File for any such Original Pooled Mortgage Loan, originals or
copies of all documents, certificates and opinions in the possession or under
the control of Column, with respect to the Original Pooled Column Mortgage
Loans, and KeyBank, with respect to the Original Pooled KeyBank Mortgage Loans,
that were delivered by or on behalf of the related Borrowers in connection with
the origination of such Original Pooled Mortgage Loans (provided that neither
Column nor KeyBank shall be required to deliver any attorney-client privileged
communication or any other documents or materials prepared by it

                                      -86-

or its Affiliates solely for internal credit analysis and other internal uses);
and (ii) all unapplied Reserve Funds and Escrow Payments in the possession or
under the control of Column, with respect to the Original Pooled Column Mortgage
Loans, and KeyBank, with respect to the Original Pooled KeyBank Mortgage Loans.
The Master Servicer 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 they relate to a B-Note Mortgage Loan or the
Great Lakes Crossing Companion Mortgage Loan, the related B-Note Mortgage Loan
Holder or the holder of the Great Lakes Crossing Companion Mortgage Loan, 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 Master Servicer, on or before the
Closing Date, the original or a copy of any Environmental Insurance Policy
acquired by the Depositor or an Affiliate of the Depositor, including all those
with respect to the Pooled Mortgage Loans identified in Exhibit C-3.

          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 Pooled 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 Pooled
Mortgage Loans and such other assets, together with any other Pooled 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; provided that, to the extent that a Mortgage File relates to
a Pooled A-Note Mortgage Loan or the Great Lakes Crossing Companion Mortgage
Loan, the Trustee shall also hold such Mortgage File in trust on behalf of the
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable. The Trustee or such Custodian 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. In connection with the foregoing, the Trustee hereby
certifies to each of the other parties hereto, Column and KeyBank that, as to
each Original Pooled Mortgage Loan, except as specifically identified in the
Schedule of Exceptions to Mortgage File Delivery attached hereto as Exhibit B-3,
(i) the Specially Designated Mortgage Loan Documents and all Mortgage Note
allonges are in its possession or the possession of a Custodian on its behalf,
and (ii) such Specially Designated Mortgage Loan Documents, and all Mortgage
Note allonges, 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 Pooled Mortgage Loan.

          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
filings and certification delivered in this Section 2.02(a), that the related
Mortgage File should include one state level UCC Financing Statement filing in
the state of incorporation or organization for each Borrower and one local UCC
Financing Statement filing in the county of each

                                      -87-

<PAGE>

related Mortgaged Property. The UCC-2's and UCC-3's in favor of the Trustee
referred to in clause (viii) of the definition of "Mortgage File" that are
delivered in form suitable for filing (but for the insertion of the Trustee as
assignee in some cases), will be filed in the state of incorporation or
organization of the related Borrower or the county wherein the related Mortgaged
Property is located, as so indicated on the documents provided.

          (b) On or about the 45th 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 earliest of (i) the date on which such exceptions are
eliminated and such recordation/filing has been completed, (ii) the date on
which all the affected Pooled Mortgage Loans are removed from the Trust Fund and
(iii) the second anniversary of the Closing Date), the Trustee or a Custodian on
its behalf shall review the documents delivered to it or such Custodian with
respect to each Original Pooled 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-4) to each of the other parties hereto, Column, KeyBank and
the Controlling Class Representative that, as to each Original Pooled Mortgage
Loan then subject to this Agreement (except as specifically identified in any
exception report annexed to such certification): (i) the original Mortgage Note
specified in clause (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 certifying that the original of such Mortgage Note has been lost), the
original or copy of documents specified in clauses (ii) through (v) and (vii) of
the definition of "Mortgage File" and, in the case of a hospitality property,
the documents specified in clause (viii) of the definition of "Mortgage File"
(without regard to the parenthetical), together with any other Specially
Designated Mortgage Loan Documents, have been received by it or a Custodian on
its behalf; (ii) if such report is due more than 180 days after the Closing
Date, the recordation/filing contemplated by Section 2.01(e) has been completed
(based solely on receipt by the Trustee of the particular recorded/filed
documents or an appropriate receipt of recording/filing therefor); (iii) all
documents received by it or any Custodian with respect to such Pooled 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 Pooled Mortgage Loan; and (iv) 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
Pooled Mortgage Loan Schedule with respect to the items specified in clause
(iii)(a) of the definition of "Pooled Mortgage Loan Schedule" accurately
reflects the information set forth in the related Mortgage File. At any time
subsequent to the second anniversary of the Closing Date, the Trustee shall,
upon request, prepare and deliver to the requesting party (including any
Certificateholder or Certificate Owner) an updated version of the exception
report provided for in the prior sentence.

          If Column, KeyBank or the Column Performance Guarantor substitutes a
Replacement Pooled Mortgage Loan for any Defective Pooled 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 Pooled Mortgage Loan, and the Trustee shall deliver a certification
comparable to that described in the prior paragraph, in respect of such
Replacement Pooled 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 earliest of (i) the date on which such exceptions are eliminated and
all related recording/filing has been completed, (ii) the date on which such
Replacement Pooled Mortgage Loan is removed from the Trust Fund and (iii) the
second anniversary of the date on which

                                      -88-

<PAGE>

such Replacement Pooled Mortgage Loan was added to the Trust Fund). At any time
subsequent to the second anniversary of the date on which such Replacement
Pooled Mortgage Loan is added to the Trust Fund, the Trustee shall, upon
request, prepare and deliver to the requesting party (including any
Certificateholder or Certificate Owner) an updated version of the exception
report provided for in the prior sentence.

          (c) None of the Trustee, the Master Servicer, the Special Servicer or
any Custodian is under any duty or obligation to inspect, review or examine any
of the documents, instruments, certificates or other papers relating to the
Pooled 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. Furthermore, except as expressly provided in Section 2.01(e), none
of the Trustee, the Master Servicer, the 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.

          (d) In performing the reviews contemplated by subsections (a) and (b)
above, the Trustee may conclusively rely on Column, with respect to the Original
Pooled Column Mortgage Loans, and KeyBank, with respect to the Original Pooled
KeyBank Mortgage Loans, 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 (i) through (v), clause (vii) and, in the case of any
Pooled Mortgage Loan secured by a Mortgage on a hospitality property, clause
(viii) of the definition of "Mortgage File" and any other Specially Designated
Mortgage Loan Documents, 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 Pooled Mortgage
                        Loans by Column, KeyBank and the Column Performance
                        Guarantor; the Purchase Price Security Deposit Account
                        and the Special Reserve Account.

          (a) If any party hereto discovers, or receives notice from a
non-party, that a Document Defect or Breach exists with respect to any Pooled
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 Pooled
Mortgage Loan, the Trustee shall notify the Controlling Class Representative,
the Depositor and the related Responsible Party or Parties.

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

          (b) Promptly upon its becoming aware of any Material Document Defect
or Material Breach with respect to any Pooled Mortgage Loan, the Master Servicer
(with respect to a Performing

                                      -89-

<PAGE>

Pooled Mortgage Loan) or the Special Servicer (with respect to a Specially
Serviced Pooled Mortgage Loan) shall notify the related Responsible Party or
Parties in writing of such Material Document Defect or Material Breach, as the
case may be, and direct the related Responsible Party or Parties that it or
they, as the case may be, must, not later than 90 days (or, in the case of a
Material Document Defect that consists of the failure to deliver a Specially
Designated Mortgage Loan Document, 15 days) from the receipt by the related
Responsible Party or Parties of such notice (such 90-day (or, if applicable,
15-day) period, the "Initial Resolution Period"), correct or cure such Material
Document Defect or Material Breach, as the case may be, in all material
respects, or (subject to the next paragraph and Section 2.03(e) below)
repurchase the affected Pooled Mortgage Loan (as, if and to the extent required
by the applicable Mortgage Loan Purchase Agreement and, if and to the extent
applicable, the Column Performance Guarantee), at the applicable Purchase Price;
provided that if a related Responsible Party 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 Pooled Mortgage Loan is or, as of the
Closing Date (or, in the case of a Replacement Pooled Mortgage Loan, as of the
related date of substitution), was a "qualified mortgage" within the meaning of
Section 860G(a)(3) of the Code, (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, within 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 period equal to any applicable Resolution Extension Period
(a copy of which certification shall be delivered by the Trustee to the Master
Servicer, the Special Servicer and the Controlling Class Representative), then
the related Responsible Party or Parties shall have an additional period equal
to any applicable Resolution Extension Period to complete such correction or
cure (or, upon failure to complete such correction or cure, to repurchase the
affected Pooled Mortgage Loan); and provided, further, that, in lieu of
effecting any such repurchase (but, in any event, no later than such repurchase
would have to have been completed), the related Responsible Party or Parties
shall be permitted, during the three-month period following the Closing Date (or
during the two-year period following the Closing Date if the affected Pooled
Mortgage Loan is a "defective obligation" within the meaning of Section
860G(a)(4)(B)(ii) of the Code and Treasury regulation section 1.860G-2(f)), to
replace the affected Pooled 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
applicable Mortgage Loan Purchase Agreement, the Column Performance Guarantee
(if applicable) and this Agreement. If any Pooled Mortgage Loan is to be
repurchased or replaced as contemplated by this Section 2.03, the Master
Servicer shall designate the 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 Master Servicer shall promptly notify
the Trustee when such deposit is made. Any such repurchase or replacement of a
Pooled Mortgage Loan shall be on a whole loan, servicing released basis.

          Notwithstanding the foregoing, if there exists a Breach of any
representation or warranty on the part of Column or KeyBank set forth in, or
made pursuant to, Section 4(b) or 4(d) of a Mortgage Loan Purchase Agreement
relating to whether or not the Mortgage Loan Documents or any particular
Mortgage Loan Document for any Pooled Mortgage Loan requires the related
Borrower to bear the costs and expenses associated with any particular action or
matter under such Mortgage Loan Document(s), then the Master Servicer (with
respect to a Performing Pooled Mortgage Loan) or the Special Servicer

                                      -90-

<PAGE>

(with respect to a Specially Serviced Pooled Mortgage Loan) shall direct the
warranting party in writing to wire transfer to the Collection Account, within
90 days of such party's receipt of such direction, the amount of any such costs
and expenses borne by the Trust that are the basis of such Breach. Upon its
making such deposit, the warranting party shall be deemed to have cured such
Breach in all respects. Provided that such payment is made, this paragraph
describes the sole remedy available to the Certificateholders and the Trustee on
their behalf regarding any such Breach, regardless of whether it constitutes a
Material Breach, and no related Responsible Party shall be obligated to
otherwise cure such Breach or repurchase of the affected Pooled Mortgage Loan
under any circumstances. Amounts deposited in the Collection Account pursuant to
this paragraph shall constitute "Liquidation Proceeds" for all purposes of this
Agreement (other than Section 3.11(c)).

          "Resolution Extension Period" shall mean:

               (i) for purposes of remediating a Material Breach with respect to
     any Pooled Mortgage Loan, 90 days;

               (ii) for purposes of remediating a Material Document Defect with
     respect to any Pooled Mortgage Loan that is and remains a Performing Pooled
     Mortgage Loan throughout the applicable Initial Resolution Period, the
     period commencing at the end of the applicable Initial Resolution Period
     and ending on, and including, the earlier of (A) the 90th day following the
     end of such Initial Resolution Period and (B) the 45th day following
     receipt by the related Primary Responsible Party of written notice from the
     Trustee, the Master Servicer or the Special Servicer of the occurrence of
     any Servicing Transfer Event with respect to such Pooled Mortgage Loan
     subsequent to the end of such Initial Resolution Period;

               (iii) for purposes of remediating a Material Document Defect with
     respect to any Pooled Mortgage Loan that is a Performing Pooled Mortgage
     Loan as of the commencement of the applicable Initial Resolution Period,
     but as to which a Servicing Transfer Event occurs during such Initial
     Resolution Period, the period commencing at the end of the applicable
     Initial Resolution Period and ending on, and including, the 90th day
     following the earlier of (A) the end of such Initial Resolution Period and
     (B) receipt by the related Primary Responsible Party of written notice from
     the Trustee, the Master Servicer or the Special Servicer of the occurrence
     of such Servicing Transfer Event; and

               (iv) for purposes of remediating a Material Document Defect with
     respect to any Pooled Mortgage Loan that is a Specially Serviced Mortgage
     Loan or has become a Pooled REO Loan as of the commencement of the
     applicable Initial Resolution Period, the 30th day following the end of
     such Initial Resolution Period, except that, if the related Primary
     Responsible Party did not receive written notice from the Trustee, the
     Master Servicer or the Special Servicer of the relevant Servicing Transfer
     Event as of the commencement of the applicable Initial Resolution Period,
     then such Servicing Transfer Event will be deemed to have occurred during
     such Initial Resolution Period and clause (iii) of this definition will be
     deemed to apply;

provided that, except as otherwise set forth in the following two provisos,
there shall be no Resolution Extension Period in respect of a Material Document
Defect with respect to any Pooled Mortgage Loan that arises out of the failure
to deliver a Specially Designated Mortgage Loan Document; and provided, further,
that if a Material Document Defect exists with respect to any Pooled Mortgage
Loan, and if a

                                      -91-

<PAGE>

related Responsible Party escrows with the Master Servicer, prior to the end of
the Initial Resolution Period and any Resolution Extension Period otherwise
applicable to the remediation of such Material Document Defect without regard to
this proviso, cash in the amount of the then Purchase Price for such Pooled
Mortgage Loan and subsequently delivers to the Master Servicer, on a monthly
basis, such additional cash as may be necessary to maintain a total escrow equal
to the Purchase Price for such Pooled Mortgage Loan as such price may increase
over time (the total amount of cash delivered to the Master Servicer with
respect to any Pooled Mortgage Loan as contemplated by this proviso or the
immediately following proviso, the "Purchase Price Security Deposit"), then the
Resolution Extension Period applicable to the remediation of such Material
Document Defect shall be extended until the earliest of (i) the second
anniversary of the Closing Date, (ii) the date on which such Pooled Mortgage
Loan is no longer outstanding and part of the Trust Fund and (iii) if such
Pooled Mortgage Loan becomes a Specially Serviced Pooled Mortgage Loan, the
date, if any, on which the Special Servicer determines in its reasonable
judgment that such Material Document Defect will materially interfere with or
delay the realization against the related Mortgaged Property or materially
increase the cost thereof; and provided, further, that if the Material Document
Defect referred to in the preceding proviso consists of a failure to deliver a
Specially Designated Mortgage Loan Document, and if a related Responsible Party
delivers to the Master Servicer a Purchase Price Security Deposit equal to 25%
of the outstanding principal balance of the subject Pooled Mortgage Loan, then
the Resolution Extension Period applicable to the remediation of such Material
Document Defect shall be extended to the 15th day following the end of the
applicable Initial Resolution Period.

          The Master Servicer shall establish, and maintain any Purchase Price
Security Deposit delivered to it with respect to any Pooled Mortgage Loan in,
one or more accounts (individually and collectively, a "Purchase Price Security
Deposit Account"), each of which shall be an Eligible Account, and shall be
entitled to make withdrawals from the Purchase Price Security Deposit for any
Pooled Mortgage Loan maintained in such account(s) for the following purposes:
(i) to cover any costs and expenses resulting from the applicable Material
Document Defect; (ii) upon any discounted payoff or other liquidation of such
Pooled Mortgage Loan, to cover any Realized Loss related thereto; and (iii) if
the Responsible Party that delivered the subject Purchase Price Security Deposit
so directs, or if the balance on deposit in such Purchase Price Security Deposit
Account declines, and for 45 days remains, below the Purchase Price for such
Pooled Mortgage Loan (except where a Purchase Price Security Deposit equal to
25% of the outstanding principal balance of the subject Pooled Mortgage Loan is
permitted to be delivered in order to obtain a 15-day Resolution Extension
Period with respect to the failure to deliver a Specially Designated Mortgage
Loan Document), or if such Material Document Defect is not remedied on or before
the second anniversary of the Closing Date, or if such Pooled Mortgage Loan
becomes a Specially Serviced Mortgage Loan and the Special Servicer determines,
in its reasonable judgment that such Material Document Defect will materially
interfere with or delay the realization against the related Mortgaged Property
or materially increase the cost thereof, to apply the Purchase Price Security
Deposit to a full or partial, as applicable, payment of the Purchase Price for
such Pooled Mortgage Loan. Any amounts withdrawn by the Master Servicer from the
Purchase Price Security Deposit Account for any Pooled Mortgage Loan shall be
deposited by the Master Servicer into the Collection Account. Any withdrawals
from a Purchase Price Security Deposit Account shall be deemed to be
"Liquidation Proceeds" for the purposes of this Agreement (other than Section
3.11(c)). Any Purchase Price Security Deposit Account, and any Purchase Price
Security Deposit, shall be part of the Trust Fund but outside any REMIC Pool or
Grantor Trust Pool. The investment of funds in the Purchase Price Security
Deposit Accounts shall be governed by the terms of the respective Mortgage Loan
Purchase Agreements. The Responsible Party that delivered the Purchase Price
Security Deposit

                                      -92-

<PAGE>

for any Pooled Mortgage Loan may obtain the release of such Purchase Price
Security Deposit (net of any amounts payable therefrom as contemplated by the
first sentence of this paragraph) upon such Pooled Mortgage Loan's being paid in
full or otherwise satisfied, liquidated or removed from the Trust Fund or upon
the subject Material Document Defect's being remedied in all material respects.

          If one or more (but not all) of the Pooled Mortgage Loans constituting
a Cross-Collateralized Group are to be repurchased or replaced by a related
Responsible Party in connection with a Material Breach or a Material Document
Defect as contemplated by this Section 2.03, then, prior to the subject
repurchase or substitution, the Master Servicer (with respect to Performing
Pooled Mortgage Loans) or the Special Servicer (with respect to Specially
Serviced Pooled Mortgage Loans) shall use its reasonable efforts, subject to the
terms of the affected Pooled 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 Pooled Mortgage Loans in such Cross-Collateralized Group that are to
be repurchased or replaced, on the one hand, and the remaining Pooled Mortgage
Loans therein, on the other hand, such that those two groups of Pooled Mortgage
Loans are each secured only by the Mortgaged Properties identified in the Pooled
Mortgage Loan Schedule as directly corresponding thereto (as to each such group,
the "Primary Real Property Collateral"); provided that no such termination shall
be effected unless and until the Master Servicer and the Trustee have received
from the subject Responsible Party (i) an Opinion of Counsel addressed to the
Trustee and the Master Servicer from Independent counsel to the effect that such
termination will not cause an Adverse REMIC Event to occur with respect to any
REMIC Pool or an Adverse Grantor Trust Event with respect to any Grantor Trust
Pool 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 the subject 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
Master Servicer with a limited power of attorney that enables the Master
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 Master Servicer. The Master Servicer shall advance all costs
and expenses incurred by the Trustee and the 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 Pooled Mortgage Loan(s) to be
repurchased or replaced. Neither the Master Servicer nor the 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
Master Servicer or the Special Servicer, as the case may be.

          If the cross-collateralization of any Cross-Collateralized Group of
Pooled Mortgage Loans cannot be terminated as contemplated by the prior
paragraph for any reason (including the failure of the related Responsible Party
or Parties to satisfy any of the conditions set forth in the first proviso to
the first sentence of the prior paragraph), and if no related Responsible Party
has elected to purchase the entire affected Cross-Collateralized Group, and if
such Cross-Collateralized Group is then subject to this Agreement, then, to the
extent that a related Responsible Party is required to repurchase or replace any
Pooled Mortgage Loan in that Cross-Collateralized Group in the manner prescribed
above while the Trust continues to hold any other Pooled Mortgage Loan in that
Cross-Collateralized Group, the related Mortgage Loan Purchase Agreement shall
provide for the Trustee, on behalf of the Trust, and the related

                                      -93-

<PAGE>

Primary Responsible Party each to agree to forbear from enforcing any remedies
against the other's Primary Real Property Collateral; provided that the Trustee
and the Master Servicer shall have received from the related Primary Responsible
Party or any other related Responsible Party an Opinion of Counsel rendered by
Independent counsel to the effect that (i) the exercise of remedies by a related
Responsible Party, on the one hand, or the Trust, on the other hand, with
respect to the Primary Real Property Collateral securing the respective Pooled
Mortgage Loan(s) in such Cross-Collateralized Group held by such party would not
materially and adversely affect the rights of the other such party to proceed
against the Primary Real Property Collateral for the respective Pooled Mortgage
Loan(s) in such Cross-Collateralized Group held by such other party and (ii) the
foregoing arrangement would not result in an Adverse REMIC Event with respect to
any REMIC Pool or an Adverse Grantor Trust Event with respect to any Grantor
Trust Pool. Any reserve or other cash collateral or letters of credit securing
the subject Cross-Collateralized Group shall be allocated between the Pooled
Mortgage Loans therein held by the related Responsible Party or Parties, on the
one hand, and the Trust, on the other hand, in accordance with the related
Mortgage Loan Documents, or otherwise on a pro rata basis based upon the
outstanding principal balances of their respective Pooled Mortgage Loans in such
Cross-Collateralized Group. All other terms of the Pooled Mortgage Loans in such
Cross-Collateralized Group shall remain in full force and effect, without any
modification thereof. The Borrowers under the respective Cross-Collateralized
Groups of Pooled Mortgage Loans are intended third-party beneficiaries of the
provision set forth in this paragraph. The provisions of this paragraph may not
be modified with respect to any Pooled Mortgage Loan in a Cross-Collateralized
Group without the related Borrower's consent.

          If the cross-collateralization of any Cross-Collateralized Group of
Pooled Mortgage Loans cannot be terminated as contemplated by the second
preceding paragraph for any reason (including the failure of the related
Responsible Party or Parties to satisfy any of the conditions set forth in the
first proviso to the first sentence of the second preceding paragraph), and the
forbearance arrangement in respect of such Cross-Collateralized Group cannot be
effected as contemplated by the preceding paragraph for any reason (including
the failure of the related Responsible Party or Parties to satisfy any of the
conditions set forth in the proviso to the first sentence of the prior
paragraph), then the entire Cross-Collateralized Group shall be repurchased or
replaced if the subject Material Breach or Material Document Defect, as the case
may be, is not remedied in all material respects by the end of the applicable
Initial Resolution Period and any applicable Resolution Extension Period.

          Whenever one or more mortgage loans are substituted for a Defective
Pooled Mortgage Loan by a related Responsible Party in connection with a
Material Breach or a Material Document Defect as contemplated by this Section
2.03, the Master Servicer shall direct the Responsible Party effecting the
substitution to deliver the related Mortgage File to the Trustee, to certify
that such substitute mortgage loan satisfies or such substitute 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 Pooled Mortgage
Loan as contemplated by this Section 2.03 if the Pooled Mortgage Loan to be
replaced is the Great Lakes Crossing Pooled Mortgage Loan, the Ritz-Carlton Key
Biscayne Pooled Mortgage Loan or was itself a Replacement Pooled Mortgage Loan,
in which case, absent a cure of the relevant Material Breach or Material
Document Defect, the affected Pooled Mortgage Loan will be required to be
repurchased as contemplated hereby. Monthly Payments due with respect to each
Replacement Pooled 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 April 2003 and on
or prior to the related date of substitution, shall be part of the Trust Fund.
Monthly Payments due with respect to

                                      -94-

<PAGE>

each Replacement Pooled 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) after the related date of substitution, shall not
be part of the Trust Fund and are to be remitted by the Master Servicer to the
Responsible Party effecting the related substitution promptly following receipt.

          If the related Borrower seeks to defease any Exhibit B-5 Mortgage Loan
prior to the second anniversary of the Closing Date in accordance with the
related Mortgage Loan Documents, then the Master Servicer shall direct Column
and, if obligated under the Column Performance Guarantee, the Column Performance
Guarantor that they must repurchase that Exhibit B-5 Mortgage Loan (it being
acknowledged that each Exhibit B-5 Mortgage Loan is an Original Pooled Column
Mortgage Loan) at the Purchase Price prior to the occurrence of such defeasance,
such repurchase to be on a whole loan, servicing released basis. Further, if
that Exhibit B-5 Mortgage Loan is the Sully Place Pooled Mortgage Loan, then the
Master Servicer shall direct Column and, if obligated under the Column
Performance Guarantee, the Column Performance Guarantor to pay concurrently with
such repurchase the Additional Sully Place Yield Maintenance Amount. The Master
Servicer shall designate the Collection Account as the account to which such
Purchase Price and, if applicable, the Additional Sully Place Yield Maintenance
Amount shall be deposited. In connection with any repurchase of any Exhibit B-5
Mortgage Loan as contemplated by this Section 2.03(b), the Trustee shall effect
a "qualified liquidation" of the related Loan REMIC in accordance with the REMIC
Provisions.

          If any Pooled Mortgage Loan is to be repurchased or replaced by a
Responsible Party in connection with a Material Breach or a Material Document
Defect or any Exhibit B-5 Mortgage Loan is to be repurchased by Column or the
Column Performance Guarantor in connection with an Early Defeasance as
contemplated by this Section 2.03, the Master Servicer shall direct such
Responsible Party or Column, as applicable, to amend the Pooled Mortgage Loan
Schedule to reflect the removal of the subject Deleted Mortgage Loan and, if
applicable, the substitution of the related Replacement Pooled Mortgage Loan(s);
and, upon its receipt of such amended Pooled Mortgage Loan Schedule, the Master
Servicer shall deliver or cause the delivery of such amended Pooled Mortgage
Loan Schedule to the other parties hereto. Upon any substitution of one or more
Replacement Pooled Mortgage Loans for a Deleted Mortgage Loan, such Replacement
Pooled Mortgage Loan(s) shall become part of the Trust Fund and be subject to
the terms of this Agreement in all respects.

          The reasonable "out-of-pocket" costs and expenses incurred by the
Master 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 or Parties or
reimbursed from a Purchase Price Security Deposit Account or a Special Reserve
Account or under a Recording Omission Credit.

          (c) Upon receipt of an Officer's Certificate from the Master Servicer
to the effect that the full amount of the Purchase Price or Substitution
Shortfall Amount (as the case may be) and, if applicable, the Additional Sully
Place Yield Maintenance Amount for any Pooled Mortgage Loan repurchased or
replaced by a Responsible Party in connection with a Material Breach or a
Material Document Defect or any Exhibit B-5 Mortgage Loan repurchased by Column
or the Column Performance Guarantor in connection with an Early Defeasance, in
any event as contemplated by this Section 2.03, has been deposited in the
Collection Account, and further, if applicable, upon receipt of the Mortgage
File for each Replacement Pooled 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

                                      -95-

<PAGE>

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 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
ownership of the Deleted Mortgage Loan, and the Master Servicer shall notify the
affected Borrowers of the transfers of the Deleted Mortgage Loan(s) and any
Replacement Pooled Mortgage Loan(s). In connection with any such repurchase or
substitution by KeyBank, Column or the Column Performance Guarantor in
connection with a Material Breach, a Material Document Defect or an Early
Defeasance as contemplated by this Section 2.03, each of the Master Servicer and
the 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 Master Servicer or the 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 reasonable
"out-of-pocket" costs and expenses, including reasonable attorneys' fees and
expenses, incurred by the Master Servicer, the Special Servicer and/or the
Trustee pursuant to this Section 2.03(c), to the extent not collected from
KeyBank, Column or the Column Performance Guarantor, as applicable, or
reimbursed from a Purchase Price Security Deposit Account or a Special Reserve
Account or under a Recording Omission Credit, shall be reimbursable to each of
them as Servicing Advances in respect of the affected Pooled Mortgage Loan.

          (d) The respective Mortgage Loan Purchase Agreements and the Column
Performance Guarantee provide the sole remedies available to the
Certificateholders, or the Trustee on their behalf, respecting any Breaches
and/or Document Defects. If a related Responsible Party defaults on its
obligations to repurchase or replace any Pooled Mortgage Loan in connection with
a Material Breach or Material Document Defect as contemplated by this Section
2.03, the Master Servicer (with respect to Performing Pooled Mortgage Loans) or
the Special Servicer (with respect to Specially Serviced Pooled Mortgage Loans)
shall promptly notify the Trustee, and the Trustee shall notify the
Certificateholders. Thereafter, the Master Servicer (with respect to Performing
Pooled Mortgage Loans) or the Special Servicer (with respect to Specially
Serviced Pooled Mortgage Loans) shall take such actions on behalf of the Trust
with respect to the enforcement of such repurchase/substitution obligations (and
if the Master Servicer or the Special Servicer, as applicable, is notified or
otherwise becomes aware of a default on the part of Column or KeyBank, as
applicable, in respect of its obligations under the second paragraph of Section
2(c) of a Mortgage Loan Purchase Agreement, the Master Servicer (with respect to
Performing Pooled Mortgage Loans) or the Special Servicer (with respect to
Specially Serviced Pooled Mortgage Loans) shall also take such actions on behalf
of the Trust with respect to the enforcement of such obligations of Column or
KeyBank, as applicable), including the institution and prosecution of
appropriate legal proceedings, as the Master Servicer (or, if applicable, the
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 Master Servicer, the 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 or Parties or reimbursed from a Purchase Price
Security Deposit Account or a Special Reserve Account or under a Recording
Omission Credit, shall constitute Servicing Advances in respect of the affected
Pooled Mortgage Loan.

          (e) If, on or after October 11, 2004, any related Responsible Party
receives notice of a Material Document Defect with respect to any Pooled
Mortgage Loan, which Material Document Defect

                                      -96-

<PAGE>

constitutes a Recording Omission, then such Responsible Party may, with the
consent of the Controlling Class Representative, which consent may be granted or
withheld in its sole discretion, in lieu of repurchasing or replacing such
Pooled Mortgage Loan (as and to the extent contemplated by Section 2.03(b)
above), but in no event later than such repurchase would have to have been
completed, establish a Recording Omission Credit or a Recording Omission Reserve
with the Master Servicer. In furtherance of the preceding sentence, (A) the
Master Servicer shall establish one or more accounts (collectively, the "Special
Reserve Account") with respect to the subject Pooled Mortgage Loan, each of
which shall be an Eligible Account; (B) the Master Servicer shall deposit any
Recording Omission Reserve into the Special Reserve Account within one Business
Day after receipt; and (C) the Master Servicer shall administer the Special
Reserve Account in accordance with the terms of the applicable Mortgage Loan
Purchase Agreement. In the event that the Master Servicer is entitled to apply
any related Recording Omission Reserve or to draw upon any related Recording
Omission Credit to cover losses or expenses directly incurred by the Trust as a
result of a Recording Omission with respect to any Pooled Mortgage Loan, then
prior to making a Servicing Advance or incurring an Additional Trust Fund
Expense to cover any losses or expenses directly resulting from such Recording
Omission, the Master Servicer shall draw upon such related Recording Omission
Reserve (out of the Special Reserve Account) or upon such related Recording
Omission Credit, as the case may be, up to the amount of such losses or
expenses, and shall deposit the funds from such draw into the Collection
Account, and such amounts shall be deemed to be "Liquidation Proceeds" for all
purposes of this Agreement (other than Section 3.11(c)) and shall be applied to
cover such losses or expenses. The Recording Omission Reserve or Recording
Omission Credit (or any unused balance thereof) delivered by a related
Responsible Party with respect to any Pooled Mortgage Loan shall be released to
such Responsible Party by the Master Servicer upon the earlier of (i) the curing
of all Recording Omissions with respect to such Pooled Mortgage Loan and (ii)
the removal of such Pooled Mortgage Loan from the Trust Fund. The Special
Reserve Account, and any Recording Omission Reserves and Recording Title Policy
Credits, shall be part of the Trust Fund but outside any REMIC Pool or Grantor
Trust Pool. The investment of funds in the Special Reserve Accounts shall be
governed by the terms of the respective Mortgage Loan Purchase Agreements.

          (f) If the related Primary Responsible Party disputes that a Material
Document Defect or Material Breach exists with respect to a Pooled Mortgage Loan
or otherwise refuses (i) to effect a correction or cure of such Material
Document Defect or Material Breach, (ii) to repurchase the affected Pooled
Mortgage Loan from the Trust or (iii) to replace such Pooled Mortgage Loan with
a Qualifying Substitute Mortgage Loan, each in accordance with the applicable
Mortgage Loan Purchase Agreement, then provided that (i) the applicable Initial
Resolution Period and any applicable Resolution Extension Period has expired and
(ii) the Pooled Mortgage Loan is then in default and is then a Specially
Serviced Mortgage Loan, the Special Servicer may, subject to the Servicing
Standard, modify, work-out or foreclose, sell or otherwise liquidate (or permit
the liquidation of) the Pooled Mortgage Loan pursuant to the terms of this
Agreement, while pursuing the repurchase claim, and such action shall not be a
defense to the repurchase claim or alter the applicable Purchase Price.

          The related Responsible Party or Parties shall be notified promptly
and in writing by the Special Servicer of any offer that it receives to purchase
an REO Property as to which there is any alleged Material Document Defect or
Material Breach. Upon the receipt of such notice by a related Responsible Party,
such Responsible Party shall then have the right to purchase such REO Property
from the Trust at a purchase price equal to the amount of such offer. A related
Responsible Party shall have three (3) Business Days to purchase such REO
Property from the date that it was notified of such offer. The Special Servicer
shall be obligated to provide the related Responsible Party or Parties with the
most

                                      -97-

<PAGE>

recent appraisal or other third-party reports relating to an REO Property within
its possession to enable the related Responsible Party or Parties to evaluate
such REO Property. Any sale of a Pooled Mortgage Loan, or foreclosure upon such
Pooled Mortgage Loan and sale of an REO Property, to a Person other than a
related Responsible Party or Parties shall be (i) without recourse of any kind
(either expressed or implied) by such Person against the related Responsible
Party or Parties and (ii) without representation or warranty of any kind (either
expressed or implied) by the related Responsible Party or Parties to or for the
benefit of such person.

          The fact that a Material Document Defect or Material Breach is not
discovered until after foreclosure (but in all instances prior to the sale of
the subject Pooled Mortgage Loan or REO Property) shall not prejudice any claim
against the related Responsible Party or Parties for repurchase of the subject
Pooled Mortgage Loan or REO Property. The provisions of this Section 2.03
regarding remedies against the related Responsible Party or Parties for a
Material Breach or Material Document Defect with respect to any Pooled Mortgage
Loan shall also apply to the related REO Property.

          If the related Primary Responsible Party fails to correct or cure the
Material Document Defect or Material Breach or purchase the subject REO
Property, then the provisions above regarding notice of offers related to such
REO Property and the related Primary Responsible Party's right to purchase such
REO Property shall apply. If a court of competent jurisdiction issues a final
order that the related Primary Responsible Party is or was obligated to
repurchase the related Pooled Mortgage Loan or REO Property or the related
Primary Responsible Party otherwise accepts liability, then, after the
expiration of any applicable appeal period, but in no event later than the
termination of the Trust pursuant to this Agreement, the related Primary
Responsible Party will be obligated to pay to the Trust the amount, if any, by
which the applicable Purchase Price exceeds any Liquidation Proceeds received
upon such liquidation (including those arising from any sale to the related
Primary Responsible Party); provided that the prevailing party in such action
shall be entitled to recover all costs, fees and expenses (including reasonable
attorneys' fees) related thereto.

          SECTION 2.04. Representations and Warranties of the Depositor.

          (a) The Depositor hereby represents and warrants to each of the other
parties hereto and for the benefit of the Certificateholders, as of the Closing
Date, that:

               (i) The Depositor is a corporation duly organized, validly
     existing and in good standing under the laws of the State of Delaware.

               (ii) The Depositor's execution and delivery of, performance
     under, and compliance with this Agreement, will not violate the Depositor's
     organizational documents or constitute a default (or an event which, with
     notice or lapse of time, or both, would constitute a default) under, or
     result in the breach of, any material agreement or other 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
     Depositor to perform its obligations under this Agreement or the financial
     condition of the Depositor.

               (iii) The Depositor has the full power and authority to own its
     properties, to conduct its business as presently conducted by it and to
     enter into and consummate all transactions involving the Depositor
     contemplated by this Agreement, has duly authorized the

                                      -98-

<PAGE>

     execution, delivery and performance of this Agreement, and has duly
     executed and delivered this Agreement.

               (iv) This Agreement, assuming due authorization, execution and
     delivery by each of the other parties hereto, constitutes a valid, legal
     and binding obligation of the 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
     principles of equity, regardless of whether such enforcement is considered
     in a proceeding in equity or at law.

               (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,
     except (A) for those consents, approvals, authorizations or orders that
     previously have been obtained, (B) such as may be required under the blue
     sky laws of any jurisdiction in connection with the purchase and sale of
     the Certificates by the Underwriters, and (C) any recordation of the
     assignments of Mortgage Loan Documents to the Trustee pursuant to Section
     2.01(e), which has not yet been completed.

               (vii) The Depositor's transfer of the Original Pooled 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 transfer or similar law in effect in any applicable
     jurisdiction.

               (viii) The Depositor is not transferring the Original Pooled
     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
     Pooled Mortgage Loans to the Trustee, pursuant to Section 2.01(b).

               (x) After giving effect to its transfer of the Original Pooled
     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.

               (xi) The Depositor does not intend to, and does not believe that
     it will, incur debts or obligations beyond its ability to pay such debts
     and obligations as they mature.

                                      -99-

<PAGE>

               (xii) No proceedings looking toward merger, liquidation,
     dissolution or bankruptcy of the Depositor are pending or contemplated.

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

               (xiv) Immediately prior to the transfer of the Original Pooled
     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 Pooled Mortgage Loan as was transferred to
     it by Column 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 Pooled 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 Pooled 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, and the Depositor has not transferred its right,
     title and interest in and to any Original Pooled Mortgage Loan other than
     as contemplated by this Agreement.

               (xvi) Except for any actions that are the express responsibility
     of another party hereunder or under either 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 Pooled
     Mortgage Loans by the Depositor to the Trustee.

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

          SECTION 2.05. Representations and Warranties of the Master Servicer.

          (a) The Master Servicer hereby represents and warrants to each of the
other parties hereto and for the benefit of the Certificateholders, as of the
Closing Date, that:

               (i) The Master Servicer is a corporation duly organized, validly
     existing and in good standing under the laws of the State of Ohio, and the
     Master Servicer is in compliance with the laws of each State in which any
     Mortgaged Property is located to the extent necessary to ensure the
     enforceability of each Mortgage Loan and to perform its obligations under
     this Agreement.

                                     -100-

<PAGE>

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

               (iii) The Master Servicer has the full power and authority to
     enter into and consummate all transactions involving the Master Servicer
     contemplated by this Agreement, has duly authorized the execution, delivery
     and performance of this Agreement, and has duly executed and delivered this
     Agreement.

               (iv) This Agreement, assuming due authorization, execution and
     delivery by each of the other parties hereto, constitutes a valid, legal
     and binding obligation of the Master Servicer, enforceable against the
     Master Servicer 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 principles of equity, regardless of whether such
     enforcement is considered in a proceeding in equity or at law.

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

               (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 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 Master Servicer to perform its obligations under this
     Agreement.

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

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

               (ix) The Master Servicer has examined each of the Sub-Servicing
     Agreements entered into by the Master Servicer that will be in effect as of
     the Closing Date with respect to

                                     -101-

<PAGE>

     the Mortgage Loans, and each such Sub-Servicing Agreement complies with the
     requirements of Section 3.22(a) in all material respects.

          (b) The representations and warranties of the Master Servicer set
forth in Section 2.05(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 of such representations and warranties that
materially and adversely affects the interests of the Certificateholders or any

in Section 2.05(a), subject to such appropriate modifications to the
representation and warranty set forth in Section 2.05(a)(i) to accurately
reflect such successor's jurisdiction of organization and whether it is a

          (a) The Special Servicer hereby represents and warrants to each of the

               (i) The Special Servicer is a corporation duly organized, validly
     existing and in good standing under the laws of the State of Ohio, and the
     Special Servicer is in compliance with the laws of each State in which any

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

               (iii) The Special Servicer has the full power and authority to
     enter into and consummate all transactions involving the Special Servicer
     contemplated by this Agreement, has duly authorized the execution, delivery

               (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 Special Servicer, enforceable against the
     Special Servicer in accordance with the terms hereof, subject to (A)
     applicable bankruptcy, insolvency, reorganization, receivership, moratorium

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

               (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 Special 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 Special Servicer to perform its obligations under this
     Agreement.

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

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

               (ix) As of the Closing Date, the Special Servicer is not a party
     to any Sub-Servicing Agreement providing for the performance of duties of
     the Special Servicer by any Sub-Servicers with respect to any of the
     Mortgage Loans or REO Properties.

          (b) The representations and warranties of the Special Servicer set
forth in Section 2.06(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 of such representations and warranties that
materially and adversely affects the interests of the Certificateholders or any
party hereto, the party discovering such breach shall give prompt written notice
to each of the other parties hereto.

          (c) Any successor 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 2.06(a), subject to such appropriate modifications to the
representation and warranty set forth in Section 2.06(a)(i) to accurately
reflect such successor's jurisdiction of organization and whether it is a
corporation, partnership, bank, association or other type of organization.

                        Trustee.

          (a) The Trustee hereby represents and warrants to, and covenants with,

          SECTION 2.08. Creation of the Loan REMIC(s); Issuance of the Loan
                        REMIC Regular Interest(s) and the Loan REMIC Residual
                        Interest(s); Certain Matters Involving the Loan
                        REMIC(s).

          (a) It is the intention of the parties hereto that, in the case of
each Exhibit B-5 Mortgage Loan, the following segregated pool of assets
constitute a REMIC for federal income tax purposes and, further, that such
segregated pool of assets be designated as a "Loan REMIC": (i) the subject
Exhibit B-5 Mortgage Loan and any Replacement Pooled Mortgage Loan substituted
for that Exhibit B-5 Mortgage Loan, together with (A) all payments under and
proceeds of the subject Exhibit B-5 Mortgage Loan or any Replacement Pooled
Mortgage Loan substituted for that Exhibit B-5 Mortgage Loan, which payments or
proceeds are received while it is part of the subject Loan REMIC (other than any
such amounts that constitute scheduled payments of interest and principal due on
or before the Cut-off Date or, in the case of a Replacement Pooled Mortgage
Loan, on or before the related date of substitution, and exclusive of any such
amounts that constitute part of the Excess Servicing Strip or, if applicable,
Post-ARD Additional Interest or the Additional Sully Place Yield Maintenance
Amount), and (B) all documents included in the related Mortgage File and
Servicing File and any related Additional Collateral; (ii) any REO Property
acquired with respect to the subject Exhibit B-5 Mortgage Loan or any
Replacement Pooled Mortgage Loan substituted for that Exhibit B-5 Mortgage Loan;
(iii) such funds and assets as from time to time are deposited in the Collection
Account, the Distribution Account, the Interest Reserve Account, the Excess
Liquidation Proceeds Account and, if established, the REO Account with respect
to the subject Exhibit B-5 Mortgage Loan, any Replacement Pooled Mortgage Loan
substituted for that Exhibit B-5 Mortgage Loan or any related REO Property
(exclusive of any such amounts that constitute part of the Excess Servicing
Strip or, if applicable, Post-ARD Additional Interest or the Additional Sully
Place Yield Maintenance Amount); and (iv) the rights of the Depositor under the
related Mortgage Loan Purchase Agreement (other than the Additional Sully Place
Yield Maintenance Contract Right) and, if applicable, the Column Performance
Guarantee, with respect to the subject Exhibit B-5 Mortgage Loan, any
Replacement Pooled Mortgage Loan substituted for that Exhibit B-5 Mortgage Loan
or any related REO Property (exclusive of any Additional Sully Place Yield
Maintenance Amount, Recording Omission Reserve, Recording Omission Credit and/or
Purchase Price Security Deposit with respect to that Exhibit B-5 Mortgage Loan,
any Replacement Pooled Mortgage Loan substituted for that Exhibit B-5 Mortgage
Loan or any related REO Property

delivered by Column, KeyBank or the Column Performance Guarantor, as applicable,
to the Master Servicer as contemplated by Section 2.03). The Closing Date is
hereby designated as the "Startup Day" of each Loan REMIC within the meaning of
Section 860G(a)(9) of the Code.

          (b) Concurrently with the assignment of each Exhibit B-5 Mortgage Loan
and certain related assets to the Trustee pursuant to Section 2.01(b) and in
exchange therefor, the related Loan REMIC Regular Interest and the related Loan
REMIC Residual Interest shall be issued. A single separate Loan REMIC Regular
Interest shall be issued with respect to each Exhibit B-5 Mortgage Loan included
in a Loan REMIC. For purposes of this Agreement, each Loan REMIC Regular
Interest shall relate to: (i) the Exhibit B-5 Mortgage Loan in respect of which
it was issued; (ii) any Replacement Pooled Mortgage Loan substituted for that
Exhibit B-5 Mortgage Loan; and (iii) the Pooled REO Loan deemed outstanding with
respect to any REO Property acquired in respect of such Exhibit B-5 Mortgage
Loan and any Replacement Pooled Mortgage Loan substituted for that Exhibit B-5
Mortgage Loan. No Loan REMIC Regular Interest shall be certificated. Each Loan
REMIC Residual Interest, together with the REMIC I Residual Interest, the REMIC
II Residual Interest and the REMIC III Residual Interest, will be evidenced by
the Class R Certificates. The related Loan REMIC Regular Interest and related
Loan REMIC Residual Interest shall collectively constitute the entire beneficial
ownership of each Loan REMIC.

          (c) Each Loan REMIC Regular Interest shall constitute the "regular
interest" (within the meaning of Section 860G(a)(1) of the Code), and each Loan
REMIC Residual Interest shall constitute the sole "residual interest" (within
the meaning of Section 860G(a)(2) of the Code), in the related Loan REMIC. None
of the parties hereto, to the extent it is within the control thereof, shall
create or permit the creation of any other "interests" in any Loan REMIC (within
the meaning of Treasury regulation section 1.860D-1(b)(1)).

          (d) The designation for each Loan REMIC Regular Interest shall be the
identification number for the related Exhibit B-5 Mortgage Loan set forth in the
Pooled Mortgage Loan Schedule.

          (e) Each Loan REMIC Regular Interest shall have an Uncertificated
Principal Balance. As of the Closing Date, the Uncertificated Principal Balance
of each Loan REMIC Regular Interest shall equal the Cut-off Date Principal
Balance of the related Exhibit B-5 Mortgage Loan (as specified in the Pooled
Mortgage Loan Schedule). On each Distribution Date, the Uncertificated Principal
Balance of each Loan REMIC Regular Interest shall be permanently reduced by any
distributions of principal deemed made with respect to the related Loan REMIC
Regular Interest on such Distribution Date pursuant to Section 4.01(m) and,
further, by any Unfunded Principal Balance Reduction made with respect to the
related Loan REMIC Regular Interest on such Distribution Date pursuant to
Section 4.04(d). Except as provided in the preceding sentence, the
Uncertificated Principal Balance of each Loan REMIC Regular Interest shall not
otherwise be increased or reduced. Deemed distributions to REMIC I in
reimbursement of Unfunded Principal Balance Reductions with respect to each Loan
REMIC Regular Interest shall not constitute deemed distributions of principal
and shall not result in any reduction of the Uncertificated Principal Balance of
the related Loan REMIC Regular Interest.

          (f) Each Loan REMIC Regular Interest shall have a Loan REMIC
Remittance Rate. The Loan REMIC Remittance Rate with respect to each Loan REMIC
Regular Interest for any Interest Accrual Period shall be calculated as follows:

                                     -106-

<PAGE>

          (i) if, as of the Closing Date, the related Exhibit B-5 Mortgage Loan
     bears or bore, as the case may be, interest calculated on a 30/360 Basis,
     then the Loan REMIC Remittance Rate with respect to the subject Loan REMIC
     Regular Interest for any Interest Accrual Period shall equal the Net
     Mortgage Rate in effect for the related Exhibit B-5 Mortgage Loan as of the
     Closing Date; and

          (ii) if, as of the Closing Date, the related Exhibit B-5 Mortgage Loan
     bears or bore, as the case may be, interest calculated on an Actual/360
     Basis, then the Loan REMIC Remittance Rate with respect to the subject Loan
     REMIC Regular Interest for any Interest Accrual Period shall (subject to
     adjustment as provided below in this clause (ii)) equal the product of (A)
     a fraction (expressed as a percentage), the numerator of which is the
     number of days in such Interest Accrual Period, and the denominator of
     which is 30, multiplied by (B) the Net Mortgage Rate in effect for the
     related Exhibit B-5 Mortgage Loan as of the Closing Date; provided that, if
     the subject Interest Accrual Period occurs during the month of January of
     2004 or any year thereafter or during the month of December of 2004 or any
     year thereafter that does not immediately precede a leap year, the Loan
     REMIC Remittance Rate with respect to the subject Loan REMIC Regular
     Interest for such Interest Accrual Period shall equal (M) the Loan REMIC
     Remittance Rate with respect to the subject Loan REMIC Regular Interest for
     such Interest Accrual Period, calculated without regard to this proviso,
     minus (N) a fraction (expressed as a percentage), the numerator of which is
     equal to 12 times any Interest Reserve Amount for the related Exhibit B-5
     Mortgage Loan, any Replacement Pooled Mortgage Loan that is substituted for
     the related Exhibit B-5 Mortgage Loan or any successor Pooled REO Loan with
     respect to the foregoing, that is to be transferred from the Distribution
     Account to the Interest Reserve Account on the related Distribution Date in
     accordance with Section 3.04(c), and the denominator of which is equal to
     the Uncertificated Principal Balance of the subject Loan REMIC Regular
     Interest outstanding immediately prior to the related Distribution Date;
     and; provided, further, that, if the subject Interest Accrual Period occurs
     during the month of February of 2004 or any year thereafter, the Loan REMIC
     Remittance Rate with respect to the subject Loan REMIC Regular Interest for
     such Interest Accrual Period shall equal (S) the Loan REMIC Remittance Rate
     with respect to the subject Loan REMIC Regular Interest for such Interest
     Accrual Period, calculated without regard to this proviso, plus (T) a
     fraction (expressed as a percentage), the numerator of which is equal to 12
     times any Interest Reserve Amount(s) for the related Exhibit B-5 Mortgage
     Loan, any Replacement Pooled Mortgage Loan that is substituted for the
     related Exhibit B-5 Mortgage Loan or any successor Pooled REO Loan with
     respect to the foregoing, that is or are to be transferred from the
     Interest Reserve Account to the Distribution Account pursuant to Section
     3.05(c) for distribution on the related Distribution Date, and the
     denominator of which is equal to the Uncertificated Principal Balance of
     the subject Loan REMIC Regular Interest outstanding immediately prior to
     the related Distribution Date.

          (g) Each Loan REMIC Regular Interest shall bear interest, and such
interest shall commence accruing on April 1, 2003. In the case of each Loan
REMIC Regular Interest, such interest shall be calculated on a 30/360 Basis and,
during each Interest Accrual Period, shall accrue at the Loan REMIC Remittance
Rate with respect to such Loan REMIC Regular Interest for such Interest Accrual
Period on the Uncertificated Principal Balance of such Loan REMIC Regular
Interest outstanding immediately prior to the related Distribution Date. The
total amount of such interest accrued with respect to each Loan REMIC Regular
Interest during each Interest Accrual Period (herein referred to as the
"Interest Accrual Amount" with respect to such Loan REMIC Regular Interest for
such Interest

                                     -107-

<PAGE>

Accrual Period) shall equal 1/12 of the product of (i) the Loan REMIC Remittance
Rate with respect to such Loan REMIC Regular Interest for such Interest Accrual
Period, multiplied by (ii) the Uncertificated Principal Balance of such Loan
REMIC Regular Interest outstanding immediately prior to the related Distribution
Date. The portion of the Interest Accrual Amount with respect to each Loan REMIC
Regular Interest for any Interest Accrual Period that shall be distributable to
REMIC I, as the holder of such Loan REMIC Regular Interest, on the related
Distribution Date pursuant to Section 4.01(m), shall be an amount (herein
referred to as the "Current Interest Distribution Amount" with respect to such
Loan REMIC Regular Interest for the related Distribution Date) equal to (i) the
Interest Accrual Amount with respect to such Loan REMIC Regular Interest for the
related Interest Accrual Period, reduced (to not less than zero) by (ii) the
portion of any Net Aggregate Prepayment Interest Shortfall for such Distribution
Date that is attributable to the related Exhibit B-5 Mortgage Loan or any
Replacement Pooled Mortgage Loan that is substituted for that Exhibit B-5
Mortgage Loan. If the entire Current Interest Distribution Amount with respect
to any Loan REMIC Regular Interest for any Distribution Date is not deemed
distributed to REMIC I, as the holder of such Loan REMIC Regular Interest, on
such Distribution Date pursuant to Section 4.01(m), then the unpaid portion of
such Current Interest Distribution Amount shall be added to, and be payable as
part of, the Carryforward Interest Distribution Amount with respect to such Loan
REMIC Regular Interest for future Distribution Dates. The "Carryforward Interest
Distribution Amount" with respect to each Loan REMIC Regular Interest for any
Distribution Date shall be an amount equal to the excess, if any, of (i) all
Current Interest Distribution Amounts with respect to such Loan REMIC Regular
Interest for all prior Distribution Dates, if any, over (ii) the total amount of
interest deemed distributed to REMIC I with respect to such Loan REMIC Regular
Interest on all such prior Distribution Dates, if any, pursuant to Section
4.01(m).

          (h) Solely for purposes of satisfying Treasury regulation section
1.860G-1(a)(4)(iii), the Latest Possible Maturity Date for each Loan REMIC
Regular Interest shall be the Rated Final Distribution Date.

          (i) No Loan REMIC Residual Interest shall have a principal balance or
bear interest.

          SECTION 2.09. Conveyance of the Loan REMIC Regular Interest(s);
                        Acceptance of the Loan REMIC Regular Interest(s) by
                        Trustee.

          The Depositor, as of the Closing Date, and concurrently with the
execution and delivery of this Agreement, does hereby assign without recourse
all of its right, title and interest in and to each Loan REMIC Regular Interest
to the Trustee for the benefit of the Holders of the REMIC III Regular Interest
Certificates and the Class R Certificates. The Trustee acknowledges the
assignment to it of each Loan REMIC Regular Interest and declares that it holds
and will hold the same in trust for the exclusive use and benefit of all present
and future Holders of the REMIC III Regular Interest Certificates and the Class
R Certificates.

                        Interests and the REMIC I Residual Interest; Certain

          (a) It is the intention of the parties hereto that the following
segregated pool of assets constitute a REMIC for federal income tax purposes
and, further, that such segregated pool of assets be designated as "REMIC I":
(i) the Pooled Mortgage Loans that are from time to time subject to this
Agreement (other than any Pooled Mortgage Loans that are held by a Loan REMIC),

(A) all payments under and proceeds of such Pooled Mortgage Loans received after
the Closing Date or, in the case of any such Pooled Mortgage Loan that is a
Replacement Pooled Mortgage Loan, after the related date of substitution (other

Date or, in the case of any such Pooled Mortgage Loan that is a Replacement
Pooled Mortgage Loan, on or before the related date of substitution, and
exclusive of any such amounts that constitute part of the Excess Servicing Strip

any REO Property acquired in respect of any Pooled Mortgage Loan (other than any
Pooled Mortgage Loans held by a Loan REMIC); (iii) such funds and assets as from
time to time are deposited in the Collection Account, the Distribution Account,
the Interest Reserve Account, the Excess Liquidation Proceeds Account and, if

Original Pooled Mortgage Loan or any such Replacement Pooled Mortgage Loan.
Furthermore, each REMIC I Regular Interest issued in respect of a Loan REMIC

outstanding with respect to any REO Property held by the corresponding Loan
REMIC. None of the REMIC I Regular Interests shall be certificated. The REMIC I
Residual Interest, together with each Loan REMIC Residual Interest, the REMIC II
Residual Interest and the REMIC III Residual Interest, shall be evidenced by the
Class R Certificates. The REMIC I Regular Interests and the REMIC I Residual
Interest shall collectively constitute the entire beneficial ownership of REMIC
I.

          (c) The REMIC I Regular Interests shall constitute the "regular
interests" (within the meaning of Section 860G(a)(1) of the Code), and the REMIC
I Residual Interest shall constitute the sole

                                     -109-

<PAGE>

"residual interest" (within the meaning of Section 860G(a)(2) of the Code), in
REMIC I. None of the parties hereto, to the extent it is within the control
thereof, shall create or permit the creation of any other "interests" in REMIC I
(within the meaning of Treasury regulation section 1.860D-1(b)(1)).

          (d) The designations for the REMIC I Regular Interests that relate to
the Great Lakes Crossing Pooled Mortgage Loan shall be "GLC-1" and GLC-2",
respectively. The designations for the REMIC I Regular Interests that relate to
the Ritz-Carlton Key Biscayne Pooled Mortgage Loan shall be "RCKB-1" and
"RCKB-2" respectively. The designation for each other REMIC I Regular Interest
shall be the identification number for the related Original Pooled Mortgage Loan
set forth in the Pooled Mortgage Loan Schedule.

          (e) Each REMIC I Regular Interest shall have an Uncertificated
Principal Balance. As of the Closing Date, (i) the Uncertificated Principal
Balance of REMIC I Regular Interest GLC-1 shall be the Cut-off Date Principal
Balance of the Great Lakes Crossing Pooled Mortgage Loan (as specified in the
Pooled Mortgage Loan Schedule) (net of $3,612,273), (ii) the Uncertificated
Principal Balance of REMIC I Regular Interest GLC-2 shall be $3,612,273)], (iii)
the Uncertificated Principal Balance of REMIC I Regular Interest RCKB-1 shall be
the Cut-off Date Principal Balance of the Ritz-Carlton Key Biscayne Pooled
Mortgage Loan (as specified in the Pooled Mortgage Loan Schedule) (net of
$15,000,000), (iv) the Uncertificated Principal Balance of REMIC I Regular
Interest RCKB-2 shall be $15,000,000, (v) the Uncertificated Principal Balance
of each REMIC I Regular Interest issued in respect of a Loan REMIC Regular
Interest held by REMIC I shall equal the initial Uncertificated Principal
Balance of such Loan REMIC Regular Interest, and (vi) the Uncertificated
Principal Balance of each other REMIC I Regular Interest shall equal the Cut-off
Date Principal Balance of the related Original Pooled Mortgage Loan (as
specified in the Pooled Mortgage Loan Schedule). On each Distribution Date, the
Uncertificated Principal Balance of each REMIC I Regular Interest shall be
permanently reduced by any distributions of principal deemed made with respect
to such REMIC I Regular Interest on such Distribution Date pursuant to Section
4.01(l) and, further, by any Unfunded Principal Balance Reduction made with
respect to such REMIC I Regular Interest on such Distribution Date pursuant to
Section 4.04(c). Except as provided in the preceding sentence, the
Uncertificated Principal Balance of each REMIC I Regular Interest shall not
otherwise be increased or reduced. Deemed distributions to REMIC II in
reimbursement of Unfunded Principal Balance Reductions with respect to a REMIC I
Regular Interest shall not constitute deemed distributions of principal and
shall not result in any reduction of the Uncertificated Principal Balance of
such REMIC I Regular Interest.

          (f) Each REMIC I Regular Interest shall have a REMIC I Remittance
Rate. With respect to each REMIC I Regular Interest issued in respect of a Loan
REMIC Regular Interest held by REMIC I, the REMIC I Remittance Rate for any
Interest Accrual Period shall equal the Loan REMIC Remittance Rate in respect of
such Loan REMIC Regular Interest for such Interest Accrual Period. With respect
to REMIC I Regular Interest GLC-2, the REMIC I Remittance Rate for any Interest
Accrual Period shall equal the product of (i) 5.8420% per annum, multiplied by
(ii) a fraction (expressed as a percentage), the numerator of which is the
number of days in such Interest Accrual Period, and the denominator of which is
30. With respect to REMIC I Regular Interest RCKB-2, the REMIC I Remittance Rate
for any Interest Accrual Period shall equal the product of (i) 6.3179% per
annum, multiplied by (ii) a fraction (expressed as a percentage), the numerator
of which is the number of days in such Interest Accrual Period, and the
denominator of which is 30. With respect to any other particular REMIC I Regular
Interest, the REMIC I Remittance Rate for any Interest Accrual Period shall be
calculated as follows:

                                     -110-

<PAGE>

               (i) if, as of the Closing Date, the related Original Pooled
     Mortgage Loan bears or bore, as the case may be, interest calculated on a
     30/360 Basis, then the REMIC I Remittance Rate with respect to the subject
     REMIC I Regular Interest for any Interest Accrual Period shall equal the
     Net Mortgage Rate in effect for the related Original Pooled Mortgage Loan
     as of the Closing Date; and

               (ii) if, as of the Closing Date, the related Original Pooled
     Mortgage Loan bears or bore, as the case may be, interest calculated on an
     Actual/360 Basis, then the REMIC I Remittance Rate with respect to the
     subject REMIC I Regular Interest for any Interest Accrual Period shall
     (subject to adjustment as provided below in this clause (ii)) equal the
     product of (A) the Net Mortgage Rate in effect for the related Original
     Pooled Mortgage Loan as of the Closing Date (or, if the subject REMIC I
     Regular Interest is REMIC I Regular Interest GLC-1, 5.18166137933% per
     annum), multiplied by (B) a fraction (expressed as a percentage), the
     numerator of which is the number of days in such Interest Accrual Period,
     and the denominator of which is 30; provided that, if the subject REMIC I
     Regular Interest corresponds to an Interest Reserve Loan, and if the
     subject Interest Accrual Period occurs during the month of January of 2004
     or any year thereafter or during the month of December of 2004 or any year
     thereafter that does not immediately precede a leap year, then the REMIC I
     Remittance Rate with respect to such REMIC I Regular Interest for such
     Interest Accrual Period shall equal (M) the REMIC I Remittance Rate with
     respect to such REMIC I Regular Interest for such Interest Accrual Period,
     calculated without regard to this proviso, minus (N) a fraction (expressed
     as a percentage), the numerator of which is equal to 12 times the related
     Interest Reserve Amount that is to be transferred from the Distribution
     Account to the Interest Reserve Account on the related Distribution Date in
     accordance with Section 3.04(c), and the denominator of which is equal to
     the Uncertificated Principal Balance of such REMIC I Regular Interest
     outstanding immediately prior to the related Distribution Date; and,
     provided, further, that if the subject REMIC I Regular Interest corresponds
     to an Interest Reserve Loan, and if the subject Interest Accrual Period
     occurs during the month of February of 2004 or any year thereafter, then
     the REMIC I Remittance Rate with respect to such REMIC I Regular Interest
     for such Interest Accrual Period shall equal (S) the REMIC I Remittance
     Rate with respect to such REMIC I Regular Interest for such Interest
     Accrual Period, calculated without regard to this proviso, plus (T) a
     fraction (expressed as a percentage), the numerator of which is equal to 12
     times any related Interest Reserve Amount(s) that is or are to be
     transferred from the Interest Reserve Account to the Distribution Account
     pursuant to Section 3.05(c) for distribution on the related Distribution
     Date, and the denominator of which is equal to the Uncertificated Principal
     Balance of such REMIC I Regular Interest outstanding immediately prior to
     the related Distribution Date.

          (g) Each REMIC I Regular Interest shall bear interest, and such
interest shall commence accruing on April 1, 2003. In the case of each REMIC I
Regular Interest, such interest shall be calculated on a 30/360 Basis and,
during each Interest Accrual Period, shall accrue at the REMIC I Remittance Rate
with respect to such REMIC I Regular Interest for such Interest Accrual Period
on the Uncertificated Principal Balance of such REMIC I Regular Interest
outstanding immediately prior to the related Distribution Date. The total amount
of such interest accrued with respect to each REMIC I Regular Interest during
each Interest Accrual Period (herein referred to as the "Interest Accrual
Amount" with respect to such REMIC I Regular Interest for such Interest Accrual
Period) shall equal 1/12 of the product of (i) the REMIC I Remittance Rate with
respect to such REMIC I Regular Interest for such Interest Accrual Period,
multiplied by (ii) the Uncertificated Principal Balance of such REMIC

                                     -111-

I Regular Interest outstanding immediately prior to the related Distribution
Date. The portion of the Interest Accrual Amount with respect to any REMIC I
Regular Interest for any Interest Accrual Period that shall be distributable to
REMIC II, as the holder of such REMIC I Regular Interest, on the related
Distribution Date pursuant to Section 4.01(l), shall be an amount (herein
referred to as the "Current Interest Distribution Amount" with respect to such
REMIC I Regular Interest for the related Distribution Date) equal to (i) the
Interest Accrual Amount with respect to such REMIC I Regular Interest for the
related Interest Accrual Period, reduced (to not less than zero) by (ii) the
portion of any Net Aggregate Prepayment Interest Shortfall for such Distribution
Date that is allocable to such REMIC I Regular Interest. For purposes of the
foregoing, the Net Aggregate Prepayment Interest Shortfall, if any, for each
Distribution Date shall be allocated: (i) to REMIC I Regular Interest GLC-2, in
an amount equal to the lesser of (A) the Interest Accrual Amount with respect to
REMIC I Regular Interest GLC-2 for the related Interest Accrual Period and (B)
the product of (1) that portion, if any, of such Net Aggregate Prepayment
Interest Shortfall that is attributable to the Great Lakes Crossing Pooled
Mortgage Loan, multiplied by (2) a fraction, the numerator of which is equal to
the Interest Accrual Amount with respect to REMIC I Regular Interest GLC-2 for
the related Interest Accrual Period, and the denominator of which is equal to
the aggregate Interest Accrual Amount with respect to REMIC I Regular Interest
GLC-1 and REMIC I Regular Interest GLC-2 for the related Interest Accrual
Period; (ii) to REMIC I Regular Interest RCKB-2, in an amount equal to the
lesser of (A) the Interest Accrual Amount with respect to REMIC I Regular
Interest RCKB-2 for the related Interest Accrual Period and (B) the product of
(1) that portion, if any, of such Net Aggregate Prepayment Interest Shortfall
that is attributable to the Ritz-Carlton Key Biscayne Pooled Mortgage Loan,
multiplied by (2) a fraction, the numerator of which is equal to the Interest
Accrual Amount with respect to REMIC I Regular Interest RCKB-2 for the related
Interest Accrual Period, and the denominator of which is equal to the aggregate
Interest Accrual Amount with respect to REMIC I Regular Interest RCKB-1 and
REMIC I Regular Interest RCKB-2 for the related Interest Accrual Period; and
(iii) to each other REMIC I Regular Interest, in an amount equal to the lesser
of (A) the Interest Accrual Amount with respect to the subject REMIC I Regular
Interest for the related Interest Accrual Period and (B) the product of (1) the
entire amount of such Net Aggregate Prepayment Interest Shortfall (exclusive of
any portion thereof that is allocable to REMIC I Regular Interest GLC-2 and/or
REMIC I Regular Interest RCKB-2), multiplied by (2) a fraction, the numerator of
which is equal to the Interest Accrual Amount with respect to the subject REMIC
I Regular Interest for the related Interest Accrual Period, and the denominator
of which is equal to the aggregate Interest Accrual Amount with respect to all
the REMIC I Regular Interests (exclusive of REMIC I Regular Interest GLC-2 and
REMIC I Regular Interest RCKB-2) for the related Interest Accrual Period. If the
entire Current Interest Distribution Amount with respect to any REMIC I Regular
Interest for any Distribution Date is not deemed distributed to REMIC II, as the
holder of such REMIC I Regular Interest, on such Distribution Date pursuant to
Section 4.01(l), then the unpaid portion of such Current Interest Distribution
Amount shall be added to, and be payable as part of, the Carryforward Interest
Distribution Amount with respect to such REMIC I Regular Interest for future
Distribution Dates. The "Carryforward Interest Distribution Amount" with respect
to any REMIC I Regular Interest for any Distribution Date shall be an amount
equal to the excess, if any, of (i) all Current Interest Distribution Amounts
with respect to such REMIC I Regular Interest for all prior Distribution Dates,
if any, over (ii) the total amount of interest deemed distributed to REMIC II
with respect to such REMIC I Regular Interest on all such prior Distribution
Dates, if any, pursuant to Section 4.01(l).

          (h) Solely for purposes of satisfying Treasury regulation section
1.860G-1(a)(4)(iii), the Latest Possible Maturity Date for each REMIC I Regular
Interest shall be the Rated Final Distribution Date.

          (i) The REMIC I Residual Interest shall not have a principal balance
and shall not bear interest.

          SECTION 2.11. Conveyance of the REMIC I Regular Interests; Acceptance
                        of the REMIC I Regular Interests by Trustee.

          The Depositor, as of the Closing Date, and concurrently with the
execution and delivery of this Agreement, does hereby assign without recourse
all of its right, title and interest in and to the REMIC I Regular Interests to
the Trustee for the benefit of the Holders of the REMIC III Regular Interest
Certificates and the Class R Certificates. The Trustee acknowledges the
assignment to it of the REMIC I Regular Interests and declares that it holds and
will hold the same in trust for the exclusive use and benefit of all present and
future Holders of the REMIC III Regular Interest Certificates and Class R
Certificates.

          SECTION 2.12. Creation of REMIC II; Issuance of the REMIC II Regular
                        Interests and the REMIC II Residual Interest; Certain
                        Matters Involving REMIC II.

          (a) It is the intention of the parties hereto that the segregated pool
of assets consisting of the REMIC I Regular Interests constitute a REMIC for
federal income tax purposes and, further, that such segregated pool of assets be
designated as "REMIC II". The Closing Date is hereby designated as the "Startup
Day" of REMIC II within the meaning of Section 860G(a)(9) of the Code.

          (b) Concurrently with the assignment of the REMIC I Regular Interests
to the Trustee pursuant to Section 2.11, and in exchange therefor, the REMIC II
Regular Interests and the REMIC II Residual Interest shall be issued. There
shall be 27 separate REMIC II Regular Interests. None of the REMIC II Regular
Interests shall be certificated. The REMIC II Residual Interest, together with
each Loan REMIC Residual Interest, the REMIC I Residual Interest and the REMIC
III Residual Interest, shall be evidenced by the Class R Certificates. The REMIC
II Regular Interests and the REMIC II Residual Interest shall collectively
constitute the entire beneficial ownership of REMIC II.

          (c) The REMIC II Regular Interests shall constitute the "regular
interests" (within the meaning of Section 860G(a)(1) of the Code), and the REMIC
II Residual Interest shall constitute the sole "residual interest" (within the
meaning of Section 860G(a)(2) of the Code), in REMIC II. None of the parties
hereto, to the extent it is within the control thereof, shall create or permit
the creation of any other "interests" in REMIC II (within the meaning of
Treasury regulation section 1.860D-1(b)(1)).

          On each Distribution Date, the Uncertificated Principal Balance of
each REMIC II Regular Interest shall be permanently reduced by any distributions
of principal deemed made with respect to such REMIC II Regular Interest on such
Distribution Date pursuant to Section 4.01(k) and, further, by any Unfunded
Principal Balance Reduction made with respect to such REMIC II Regular Interest
on such Distribution Date pursuant to Section 4.04(b). Except as provided in the
preceding sentence, the Uncertificated Principal Balance of each REMIC II
Regular Interest shall not otherwise be increased or decreased. Deemed
distributions to REMIC III in reimbursement of Unfunded Principal Balance
Reductions with respect to any REMIC II Regular Interest, shall not constitute
deemed distributions of principal and shall not result in any reduction of the
Uncertificated Principal Balance of such REMIC II Regular Interest.

          (f) Each REMIC II Regular Interest shall have a REMIC II Remittance
Rate. The REMIC II Remittance Rate with respect to REMIC II Regular Interest
GLC, for any Interest Accrual Period, shall equal the REMIC I Remittance Rate
with respect to REMIC I Regular Interest GLC-2 for such Interest Accrual Period.
The REMIC II Remittance Rate with respect to REMIC II Regular Interest RCKB, for
any Interest Accrual Period, shall equal the REMIC I Remittance Rate with
respect

                                     -114-

<PAGE>

to REMIC I Regular Interest RCKB-2 for such Interest Accrual Period. The REMIC
II Remittance Rate with respect to each other REMIC II Regular Interest, for any
Interest Accrual Period, shall equal the weighted average, expressed as a
percentage and rounded to ten decimal places, of the respective REMIC I
Remittance Rates in effect for all the REMIC I Regular Interests (other than
REMIC I Regular Interest GLC-2 and REMIC I Regular Interest RCKB-2) for such
Interest Accrual Period, weighted on the basis of the respective Uncertificated
Principal Balances of such REMIC I Regular Interests outstanding immediately
prior to the related Distribution Date.

          (g) Each REMIC II Regular Interest shall bear interest, and such
interest shall commence accruing on April 1, 2003. In the case of each REMIC II
Regular Interest, such interest shall be calculated on a 30/360 Basis and,
during each Interest Accrual Period, shall accrue at the REMIC II Remittance
Rate with respect to such REMIC II Regular Interest for such Interest Accrual
Period on the Uncertificated Principal Balance of such REMIC II Regular Interest
outstanding immediately prior to the related Distribution Date. The total amount
of such interest accrued with respect to each REMIC II Regular Interest during
each Interest Accrual Period (herein referred to as the "Interest Accrual
Amount" with respect to such REMIC II Regular Interest for such Interest Accrual
Period) shall equal 1/12 of the product of (i) the REMIC II Remittance Rate with
respect to such REMIC II Regular Interest for such Interest Accrual Period,
multiplied by (ii) the Uncertificated Principal Balance of such REMIC II Regular
Interest outstanding immediately prior to the related Distribution Date. The
portion of the Interest Accrual Amount with respect to any REMIC II Regular
Interest for any Interest Accrual Period that shall be distributable to REMIC
III, as the holder of such REMIC II Regular Interest, on the related
Distribution Date pursuant to Section 4.01(k), shall be an amount (herein
referred to as the "Current Interest Distribution Amount" with respect to such
REMIC II Regular Interest for the related Distribution Date) equal to (i) the
Interest Accrual Amount with respect to such REMIC II Regular Interest for the
related Interest Accrual Period, reduced (to not less than zero) by (ii) the
portion of any Net Aggregate Prepayment Interest Shortfall for such Distribution
Date that is allocable to such REMIC II Regular Interest. For purposes of the
foregoing, the Net Aggregate Prepayment Interest Shortfall, if any, for each
Distribution Date shall be allocated: (i) to REMIC II Regular Interest GLC, in
the amount equal to the portion, if any, of such Net Aggregate Prepayment
Interest Shortfall that was allocated to REMIC I Regular Interest GLC-2 pursuant
to Section 2.10(g); (ii) to REMIC II Regular Interest RCKB, in the amount equal
to the portion, if any, of such Net Aggregate Prepayment Interest Shortfall that
was allocated to REMIC I Regular Interest RCKB-2 pursuant to Section 2.10(g);
and (iii) to each other REMIC II Regular Interest, in an amount equal to the
lesser of (A) the Interest Accrual Amount with respect to the subject REMIC II
Regular Interest for the related Interest Accrual Period and (B) the product of
(1) the entire amount of such Net Aggregate Prepayment Interest Shortfall
(exclusive of any portion thereof that is allocable to the REMIC II Regular
Interest GLC and/or the REMIC II Regular Interest RCKB), multiplied by (2) a
fraction, the numerator of which is equal to the Interest Accrual Amount with
respect to the subject REMIC II Regular Interest for the related Interest
Accrual Period, and the denominator of which is equal to the aggregate Interest
Accrual Amount with respect to all the REMIC II Regular Interests (exclusive of
the REMIC II Regular Interest GLC and the REMIC II Regular Interest RCKB) for
the related Interest Accrual Period. If the entire Current Interest Distribution
Amount with respect to any REMIC II Regular Interest for any Distribution Date
is not deemed distributed to REMIC III, as the holder of such REMIC II Regular
Interest, on such Distribution Date pursuant to Section 4.01(k), then the unpaid
portion of such Current Interest Distribution Amount shall be added to, and be
payable as part of, the Carryforward Interest Distribution Amount with respect
to such REMIC II Regular Interest for future Distribution Dates. The
"Carryforward Interest Distribution Amount" with respect to any REMIC II Regular
Interest for any Distribution Date shall be

                                     -115-

<PAGE>

an amount equal to the excess, if any, of (i) all Current Interest Distribution
Amounts with respect to such REMIC II Regular Interest for all prior
Distribution Dates, if any, over (ii) the total amount of interest deemed
distributed to REMIC III with respect to such REMIC II Regular Interest on all
such prior Distribution Dates, if any, pursuant to Section 4.01(k).

          (h) Solely for purposes of satisfying Treasury regulation section
1.860G-1(a)(4)(iii), the Latest Possible Maturity Date for each REMIC II Regular
Interest shall be the Rated Final Distribution Date.

          (i) The REMIC II Residual Interest shall not have a principal balance
and shall not bear interest.

          SECTION 2.13. Conveyance of the REMIC II Regular Interests; Acceptance
                        of the REMIC II Regular Interests by Trustee.

          The Pass-Through Rate with respect to the Class GLC Certificates for
any Interest Accrual Period shall equal the REMIC II Remittance Rate with
respect to REMIC II Regular Interest GLC for such Interest Accrual Period.

          The Pass-Through Rate with respect to the Class RCKB Certificates for
any Interest Accrual Period shall equal the REMIC II Remittance Rate with
respect to REMIC II Regular Interest RCKB for such Interest Accrual Period.

          The Pass-Through Rate for the Class A-X Certificates for any Interest
Accrual Period shall be deemed to equal the weighted average, expressed as a
percentage and rounded to ten decimal places, of the respective REMIC III
Remittance Rates in effect for all of the Group A-X REMIC III Regular Interests
for such Interest Accrual Period, weighted on the basis of the respective
Component Notional Amounts of the Group A-X REMIC III Regular Interests
immediately prior to the related Distribution Date.

          The REMIC III Remittance Rate with respect to any Group A-X REMIC III
Regular Interest for any Interest Accrual Period shall equal the excess, if any,
of (i) the REMIC II Remittance Rate in effect during such Interest Accrual
Period for the Corresponding REMIC II Regular Interest in respect of such Group
A-X REMIC III Regular Interest, over (ii) the Adjusted REMIC II Remittance Rate
in effect during such Interest Accrual Period for the Corresponding REMIC II
Regular Interest in respect of such Group A-X REMIC III Regular Interest.

          The Pass-Through Rate for the Class A-SP Certificates for any Interest
Accrual Period shall be deemed to equal the weighted average, expressed as a
percentage and rounded to ten decimal places, of the respective REMIC III
Remittance Rates in effect for all of the Group A-SP REMIC III Regular Interests
for such Interest Accrual Period, weighted on the basis of the respective
Component Notional Amounts of the Group A-SP REMIC III Regular Interests

REMIC III Regular Interests for any Interest Accrual Period shall be as follows:

               (i) if such Interest Accrual Period occurs from and including
     April 2003 through and including March 2010, a rate per annum equal to the
     excess, if any, of (A) the lesser of the REMIC II Remittance Rate and the
     Adjusted REMIC II Remittance Rate in effect during such Interest Accrual
     Period for the Corresponding REMIC II Regular Interest in respect of such
     Group A-SP REMIC III Regular Interest, over (B) the Net Adjusted REMIC II
     Remittance Rate in effect during such Interest Accrual Period for the
     Corresponding REMIC II Regular Interest in respect of such Group A-SP REMIC
     III Regular Interest; and

               (ii) if such Interest Accrual Period occurs after March 2010, 0%
     per annum.

          (g) Each Class of REMIC III Regular Interest Certificates shall bear
interest, and such interest shall commence accruing on April 1, 2003. In the
case of each Class of REMIC III Regular Interest Certificates, such interest
shall be calculated on a 30/360 Basis and, during each Interest Accrual Period,
shall accrue at the Pass-Through Rate with respect to such Class of Certificates
for such Interest Accrual Period on the Class Principal Balance (or, in the case
of a Class of Interest Only Certificates, the Class Notional Amount) of such
Class of Certificates outstanding immediately prior to

                                      -120-

the related Distribution Date. Accordingly, the total amount of such interest
accrued with respect to any Class of REMIC III Regular Interest Certificates
during any Interest Accrual Period (herein referred to as the "Interest Accrual
Amount" with respect to such Class of Certificates for such Interest Accrual
Period) shall equal 1/12 of the product of (i) the Pass-Through Rate with
respect to such Class of Certificates for such Interest Accrual Period,
multiplied by (ii) the Class Principal Balance (or, in the case of a Class of
Interest Only Certificates, the Class Notional Amount) of such Class of
Certificates outstanding immediately prior to the related Distribution Date. The
portion of the Interest Accrual Amount with respect to a Class of Interest Only
Certificates for any Interest Accrual Period that is attributable to any
particular Component of such Class of Certificates shall be an amount (herein
referred to as the "Interest Accrual Amount" with respect to such Component for
such Interest Accrual Period) equal to 1/12 of the product of (i) the REMIC III
Remittance Rate with respect to such Component for such Interest Accrual Period,
multiplied by (ii) the Component Notional Amount of such Component immediately
prior to the related Distribution Date.

          The Class A-SP Certificates and the respective Group A-SP REMIC III
Regular Interests shall cease to accrue interest after the end of the March 2010
Interest Accrual Period.

          The portion of the Interest Accrual Amount with respect to any Class
of REMIC III Regular Interest Certificates for any Interest Accrual Period that
shall be distributable to the Holders of such Class of Certificates on the
related Distribution Date pursuant to Section 4.01(a) or Section 4.01(b), as
applicable, shall be an amount (herein referred to as the "Current Interest
Distribution Amount" with respect to such Class of Certificates for the related
Distribution Date) equal to (i) the Interest Accrual Amount with respect to such
Class of Certificates for the related Interest Accrual Period, reduced (to not
less than zero) by (ii) the portion of any Net Aggregate Prepayment Interest
Shortfall for such Distribution Date that is allocable to such Class of
Certificates. For purposes of the foregoing, the Net Aggregate Prepayment
Interest Shortfall, if any, for each Distribution Date shall be allocated: (i)
to the Class GLC Certificates, in an amount equal to the portion, if any, of
such Net Aggregate Prepayment Interest Shortfall that was allocated to REMIC II
Regular Interest GLC pursuant to Section 2.12(g); (ii) to the Class RCKB
Certificates, in an amount equal to the portion, if any, of such Net Aggregate
Prepayment Interest Shortfall that was allocated to REMIC II Regular Interest
RCKB pursuant to Section 2.12(g); and (iii) to each other Class of REMIC III
Regular Interest Certificates, in an amount equal to the lesser of (A) the
Interest Accrual Amount with respect to the subject Class of REMIC III Regular
Interest Certificates for the related Interest Accrual Period and (B) the
product of (1) the entire amount of such Net Aggregate Prepayment Interest
Shortfall (exclusive of any portion thereof that is allocable to the Class GLC
and/or Class RCKB Certificates), multiplied by (2) a fraction, the numerator of
which is equal to the Interest Accrual Amount with respect to the subject Class
of REMIC III Regular Interest Certificates for the related Interest Accrual
Period, and the denominator of which is equal to the aggregate Interest Accrual
Amount with respect to all the Classes of REMIC III Regular Interest
Certificates (exclusive of the Class GLC and RCKB Certificates) for the related
Interest Accrual Period. The portion of the Current Interest Distribution Amount
with respect to a Class of Interest Only Certificates for any Distribution Date
that is attributable to any particular Component of such Class of Certificates
shall be an amount (herein referred to as the "Current Interest Distribution
Amount" with respect to such Component for such Distribution Date) equal to (i)
the Interest Accrual Amount with respect to such Component for the related
Interest Accrual Period, reduced (to not less than zero) by (ii) such
Component's share of the portion of any Net Aggregate Prepayment Interest
Shortfall for such Distribution Date that is allocable to such Class of
Certificates. For purposes of the foregoing, any portion of the Net Aggregate
Prepayment Interest Shortfall for any Distribution Date that is allocated to

                                      -121-

a Class of Interest Only Certificates shall, in turn, be allocated among the
Components of such Class of Certificates on a pro rata basis in accordance with
their respective Interest Accrual Amounts for the related Interest Accrual
Period.

          If the entire Current Interest Distribution Amount with respect to any
Class of REMIC III Regular Interest Certificates for any Distribution Date is
not distributed to the Holders thereof on such Distribution Date pursuant to
Section 4.01(a) or Section 4.01(b), as applicable, then the unpaid portion of
such Current Interest Distribution Amount shall be added to, and be payable as
part of, the Carryforward Interest Distribution Amount with respect to such
Class of Certificates for future Distribution Dates. The "Carryforward Interest
Distribution Amount" with respect to any Class of REMIC III Regular Interest
Certificates for any Distribution Date shall be an amount equal to the excess,
if any, of (i) all Current Interest Distribution Amounts with respect to such
Class of Certificates for all prior Distribution Dates, if any, over (ii) the
total amount of interest distributed to the Holders of such Class of
Certificates on all such prior Distribution Dates, if any, pursuant to Section
4.01(a) or Section 4.01(b), as applicable. The portion of the Carryforward
Interest Distribution Amount with respect to a Class of Interest Only
Certificates for any Distribution Date that is attributable to any particular
Component of such Class of Certificates shall be an amount (herein referred to
as the "Carryforward Interest Distribution Amount" with respect to such
Component for such Distribution Date) equal to the excess, if any, of (i) all
Current Interest Distribution Amounts with respect to such Component for all
prior Distribution Dates, if any, over (ii) the total amount of interest deemed
distributed to the Holders of such Class of Certificates with respect to such
Component on all such prior Distribution Dates, if any, pursuant to Section
4.01(a).

          (h) Solely for purposes of satisfying Treasury regulation section
1.860G-1(a)(4)(iii), the Latest Possible Maturity Date for each Class of
Principal Balance Certificates, for each Component of the Class A-X Certificates
and for each Component of the Class A-SP Certificates shall be the Rated Final
Distribution Date.

          (i) The REMIC III Residual Interest shall not have a principal balance
and shall not bear interest.

Loan, the B-Note Mortgage Loan Holders and the Trustee or any of them: (i) any
and all financing statements, continuation statements and other documents or
instruments necessary to maintain the lien created by any Mortgage or other
security document in the related Mortgage File on the related Mortgaged Property
and other related collateral; (ii) any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge, or of partial or full
defeasance, and all other comparable instruments; and (iii) subject to Sections
3.08, 3.20 and 3.24, any and all assumptions, modifications, waivers,

                                      -124-

substitutions, extensions, amendments and consents. Subject to Section 3.10, the
Trustee shall, at the written request of a Servicing Officer of the Master
Servicer or the Special Servicer, furnish, or cause to be so furnished, to the
Master Servicer or the Special Servicer, as appropriate, any limited powers of
attorney and other documents (each of which shall be prepared by the Master
Servicer or the Special Servicer, as the case may be) 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 the Master Servicer or the Special Servicer.

          (c) The relationship of each of the Master Servicer and the Special
Servicer 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 agent.

          (d) In the event that there shall occur an A/B Material Default with
respect to any A/B Mortgage Loan Pair, and for so long as such A/B Material
Default shall be continuing, the Master Servicer and the Special Servicer shall
be obligated to service and administer, subject to the terms and conditions of
the related A/B Intercreditor Agreement, the related B-Note Mortgage Loan, on
behalf of the related B-Note Mortgage Loan Holder, and during any such period,
all references herein to "Mortgage Loan" and all references herein to "Specially
Serviced Mortgage Loan" shall include a B-Note Mortgage Loan that is being
serviced under this Agreement. It is understood and agreed that an A/B Material
Default shall constitute a Servicing Transfer Event with respect to the related
Pooled A-Note Mortgage Loan.

          (e) For so long as the Great Lakes Crossing Pooled Mortgage Loan or
any related REO Property is part of the Trust Fund, the Master Servicer and the
Special Servicer shall be obligated to service and administer, subject to the
terms and conditions of the Great Lakes Crossing Intercreditor Agreement, the
Great Lakes Crossing Companion Mortgage Loan (or any successor Companion REO
Loan with respect thereto), on behalf of the holder of the Great Lakes Crossing
Companion Mortgage Loan, and during any such period, all references herein to
"Mortgage Loan" and, if a Servicing Transfer Event exists, all references herein
to "Specially Serviced Mortgage Loan" shall include the Great Lakes Crossing
Companion Mortgage Loan while it is being serviced under this Agreement. In
addition, for so long as the Great Lakes Crossing Pooled Mortgage Loan or any
related REO Property is part of the Trust Fund, the Master Servicer (if the
Great Lakes Crossing Pooled Mortgage Loan is a Performing Pooled Mortgage Loan)
and the Special Servicer (if the Great Lakes Crossing Pooled Mortgage Loan is a
Specially Serviced Pooled Mortgage Loan or if the Great Lakes Crossing Mortgaged
Property has become an REO Property) shall perform the obligations of the "A-1
Noteholder" under the Great Lakes Crossing Intercreditor Agreement. If the Great
Lakes Crossing Companion Mortgage Loan should be securitized, and rated
securities should be issued in connection therewith, then with respect to each
action hereunder relating to the Great Lakes Crossing Pooled Mortgage Loan or
any related REO Property that requires the Master Servicer or the Special
Servicer to obtain written confirmation from either Rating Agency that such
action will not result in an Adverse Rating Event, the Master Servicer or the
Special Servicer, as the case may be, shall also obtain written confirmation (at
the expense of the related Borrower or such other securitization and not of the
Trust Fund) from each rating agency that has assigned a rating to the securities
backed by the Great Lakes Crossing Companion Mortgage Loan that the subject
action will likewise not result in a qualification, downgrade or withdrawal of
any rating assigned to such securities backed by the Great Lakes Crossing
Companion Mortgage Loan.

          (f) The Special Servicer hereunder shall collectively consist of: (i)
the party hereunder responsible for performing the duties of Special Servicer
with respect to the Great Lakes Crossing Total Mortgage Loan and any related REO
Property (the "GLCTML Special Servicer"); and (ii) the party hereunder
responsible for performing the duties of Special Servicer with respect to the
rest of the Mortgage Pool and any other REO Properties (the "General Special
Servicer"). For so long as the same party acts as both GLCTML Special Servicer
and as General Special Servicer, the term "Special Servicer" shall mean the
GLCTML Special Servicer and the General Special Servicer, collectively. However,
if different parties shall ever act hereunder as the GLCTML Special Servicer and
the General Special Servicer, respectively, then, unless the context clearly
requires otherwise: (i) when used in the context of imposing duties and
obligations on the Special Servicer hereunder or the performance of such duties
and obligations, the term "Special Servicer" shall mean the GLCTML Special
Servicer, insofar as such duties and obligations relate to the Great Lakes
Crossing Total Mortgage Loan or any related REO Property, and shall mean the
General Special Servicer, in all other cases (provided that, in Section 3.13,
Section 3.14 and Section 3.15, the term "Special Servicer" shall mean each of
the GLCTML Special Servicer and the General Special Servicer); (ii) when used in
the context of identifying the recipient of any information, funds, documents,
instruments and/or other items, the term "Special Servicer" shall mean the
GLCTML Special Servicer, insofar as such information, funds, documents,
instruments and/or other items relate to the Great Lakes Crossing Total Mortgage
Loan or any related REO Property, and shall mean the General Special Servicer,
in all other cases; (iii) when used in the context of granting the Special
Servicer the right to purchase Specially Designated Defaulted Pooled Mortgage
Loans pursuant to Section 3.18, the term "Special Servicer" shall mean the
GLCTML Special Servicer, if such Specially Designated Defaulted Pooled Mortgage
Loan is the Great Lakes Crossing Pooled Mortgage Loan, and shall mean the
General Special Servicer, in all other cases; (iv) when used in the context of
granting the Special Servicer the right to purchase all of the Pooled Mortgage
Loans and any REO Properties remaining in the Trust Fund pursuant to Section
9.01, the term "Special Servicer" shall mean the General Special Servicer only;
(v) when used in the context of granting the Special Servicer any protections,
limitations on liability, immunities and/or indemnities hereunder, the term
"Special Servicer" shall mean each of the GLCTML Special Servicer and the
General Special Servicer; and (vi) when used in the context of requiring
indemnification from, imposing liability on, or exercising any remedies against,
the Special Servicer for any breach of a representation, warranty or covenant
hereunder or for any negligence, bad faith or willful misconduct in the
performance of duties and obligations hereunder or any negligent disregard of
such duties and obligations or otherwise holding the Special Servicer
responsible for any of the foregoing, the term "Special Servicer" shall mean the
GLCTML Special Servicer or the General Special Servicer, as applicable. Unless
the same party is, or affiliated parties are, acting as the GLCTML Special
Servicer and the General Special Servicer, the GLCTML Special Servicer and the
General Special Servicer shall not be responsible for the actions of the other.

          SECTION 3.02. Collection of Mortgage Loan Payments.

          (a) The Master Servicer, with respect to each Performing Mortgage
Loan, and the Special Servicer, with respect to each Specially Serviced Mortgage
Loan, shall undertake reasonable efforts to collect all payments called for
under the terms and provisions of the Mortgage Loans and, in connection
therewith, shall follow such collection procedures as are consistent with
applicable law, the express terms of this Agreement and the related Mortgage
Loan Documents and, to the extent consistent with the foregoing, the Servicing
Standard; provided that the Master Servicer shall not, with respect to any ARD
Mortgage Loan after its Anticipated Repayment Date, take any enforcement action
with

                                      -126-

<PAGE>

respect to the payment of Post-ARD Additional Interest (other than the making of
requests for its collection), and the Special Servicer may do so with respect to
any Specially Serviced Mortgage Loan that is an ARD Mortgage Loan 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. Consistent with the foregoing, the Master
Servicer (as to a Performing Mortgage Loan) and the Special Servicer (as to a
Specially Serviced Mortgage Loan) may each waive any Default Charges in
connection with any specific delinquent payment on such Mortgage Loan.

          (b) At least ninety days prior to the maturity date of each Performing
Mortgage Loan that is a Balloon Mortgage Loan, the Master Servicer shall send a
notice to the related Borrower of such maturity date (with a copy to be sent to
the Special Servicer) and shall request confirmation that the Balloon Payment
will be paid by such maturity date.

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

          (a) The 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. Subject to
any terms of the related Mortgage Loan Documents 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, the Master
Servicer may make withdrawals from the Servicing Accounts, 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 the Master Servicer, the
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 related Investment Period) to the 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 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 Servicing Accounts maintained thereby, if and to the
extent required by law or the terms of the related Mortgage Loan Documents. If
the Master Servicer shall deposit in a Servicing Account any amount not required
to be deposited therein, it may at any time withdraw such amount from such
Servicing Account, any provision herein to the contrary notwithstanding.
Promptly after any

                                      -127-

<PAGE>

Escrow Payments are received by the Special Servicer from any Borrower, and in
any event within two Business Days after any such receipt, the Special Servicer
shall remit such Escrow Payments to the Master Servicer for deposit in the
applicable Servicing Account(s).

          (b) The 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 with respect to any
Mortgage Loan, the 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, the Master Servicer (or, if such Mortgage Loan is a Specially
Serviced Mortgage Loan, the Special Servicer) shall, subject to and in
accordance with the Servicing Standard, enforce the requirement of the related
Mortgage that the 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 Master Servicer shall make a Servicing Advance with respect to each
Mortgaged Property (including each Mortgaged Property relating to a Specially
Serviced Mortgage Loan) 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 Master Servicer shall not make a
Servicing Advance of any such amount if the 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 the 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 the
Master Servicer that such amounts have not been paid by the applicable penalty
date; and provided further that all Servicing Advances made in respect of the
Great Lakes Crossing Total Mortgage Loan (or any related REO Property) shall be
deemed made on a pro rata basis (by balance) on the Great Lakes Crossing Pooled
Mortgage Loan (or any successor Pooled REO Loan with respect thereto) and the
Great Lakes Crossing Companion Mortgage Loan (or any successor Companion REO
Loan with respect thereto). 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). Any Servicing Advances made in respect of the Great Lakes
Crossing Companion Mortgage Loan shall only be reimbursable hereunder out of
amounts allocable to the Great Lakes Crossing Companion Mortgage Loan (or any
successor Companion REO Loan with respect thereto); provided that Advances made
in respect of the Great Lakes Crossing Companion Mortgage Loan may also be
reimbursed out of amounts received from the holder of the Great Lakes Crossing
Companion Mortgage Loan (or any successor Companion REO Loan with respect
thereto) as and to the extent contemplated by the Great Lakes Crossing
Intercreditor Agreement. No costs incurred by the Master Servicer in effecting
the

                                      -128-

<PAGE>

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 subject
Mortgage Loan(s), notwithstanding that the terms of such Mortgage Loan(s) so
permit; provided that this sentence shall not be construed to limit the rights
of the Master Servicer or the Special Servicer on behalf of the Trust to enforce
any obligations of the related Borrower under such Mortgage Loan.

          (d) The Master Servicer shall establish and maintain one or more
accounts ("Reserve Accounts"), in which all Reserve Funds, if any, received by
it with respect to the Mortgage Loans, shall be deposited and retained. 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, the Master
Servicer may make withdrawals from the Reserve Accounts, and may apply Reserve
Funds held therein with respect to any Mortgage Loan (together with interest
earned thereon), only as follows: (i) in the case of Reserve Funds that are
intended to cover specific costs and expenses, 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 the
Master Servicer, the Special Servicer, the Trustee or any Fiscal Agent, as
applicable, for any unreimbursed Advances 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 related Investment Period) to the 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 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, the Master Servicer shall not 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) the Master Servicer has so
notified the Special Servicer in writing and has provided the Special Servicer
with any written or electronic information in the Master Servicer's possession
regarding the subject Mortgage Loan or the related Mortgaged Property that the
Special Servicer may reasonably request within ten Business Days of receiving
such written notice; and (ii) subject to Section 3.24, the Special Servicer has
consented to such release of any such Earn-Out Reserve Funds or return

                                      -129-

<PAGE>

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 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 Master Servicer (or, if it did
not request additional information, within ten Business Days after receiving
such notice)). The 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 the Reserve Accounts maintained thereby, if and to the extent required by law
or the terms of the related Mortgage Loan Documents. If the Master Servicer
shall deposit in a Reserve Account 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 the Special Servicer from any Borrower, and in any event
within two Business Days of such receipt, the Special Servicer shall remit such
Reserve Funds to the Master Servicer for deposit in the applicable Reserve
Account(s). Any out-of-pocket expenses, including reasonable attorneys' fees and
expenses, incurred by the Master Servicer to enable the Master Servicer to make
any draw under any Letter of Credit shall constitute a Servicing Advance, and
the Master Servicer 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(s).

          (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 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
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 Master
Servicer shall notify the Trustee, the Special Servicer and the Controlling
Class Representative. The Master Servicer shall promptly notify the Trustee, the
Special Servicer and the Controlling Class Representative if the Master Servicer
shall determine that the Borrower under any Mortgage Loan has failed to perform
its obligations under such 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 Account, Distribution Account, Interest
                        Reserve Account, Excess Liquidation Proceeds Account,
                        A/B Mortgage Loan Pair Custodial Accounts and GLCTML
                        Custodial Account.

          (a) The Master Servicer shall segregate and hold all funds collected
and received by it in connection with the Mortgage Pool separate and apart from
its own respective funds and general assets. In connection therewith, the Master
Servicer shall establish and maintain one or more segregated accounts or,
subject to Section 3.04(h), sub-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

                                      -130-

<PAGE>

Account. The Master Servicer shall deposit or cause to be deposited in the
Collection Account, within one Business Day of receipt by it (in the case of
payments by Borrowers or other collections on the Pooled Mortgage Loans) or as
otherwise required hereunder, the following payments and collections received or
made by or on behalf of the Master Servicer in respect of the Mortgage Pool
subsequent to the Closing Date (other than in respect of scheduled payments of
principal and interest due and payable on the Pooled Mortgage Loans on or before
their respective Due Dates in April 2003 (or, in the case of a Replacement
Pooled Mortgage Loan, on or before the related date of substitution), which
payments shall be delivered promptly to Column or its designee, with negotiable
instruments endorsed as necessary and appropriate without recourse, and other
than any of the amounts described in clauses (i) through (iv) below that are to
be deposited in an A/B Mortgage Loan Pair Custodial Account or the GLCTML
Custodial Account pursuant to Section 3.04(e) or Section 3.04(f), as
applicable):

               (i) all payments, from whatever source, or transfers from a debt
     service reserve account, on account of principal of such Pooled Mortgage
     Loans, including Principal Prepayments;

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

               (iii) all Prepayment Premiums, Yield Maintenance Charges and late
     payment charges received with respect to the Pooled Mortgage Loans;

               (iv) all Insurance Proceeds, Condemnation Proceeds and
     Liquidation Proceeds received with respect to the Pooled Mortgage Loans;

               (v) any amounts required to be deposited in the Collection
     Account 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;

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

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

               (viii) any amounts required to be transferred to the Collection
     Account from any Purchase Price Security Deposit Account pursuant to
     Section 2.03(b);

               (ix) any amounts required to be transferred to the Collection
     Account from any Special Reserve Account pursuant to Section 2.03(e);

               (x) any amounts required to be transferred to the Collection
     Account from any A/B Mortgage Loan Pair Custodial Account pursuant to
     Section 3.04(e);

               (xi) any amounts required to be transferred to the Collection
     Account from the GLCTML Custodial Account pursuant to Section 3.04(f); and

                                      -131-

<PAGE>

               (xii) insofar as they do not constitute Escrow Payments or
     Reserve Funds, any amounts relating to such Pooled Mortgage Loans 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.

          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 and amounts collected for
checks returned for insufficient funds, need not be deposited by the Master
Servicer in the Collection Account. The Master Servicer shall promptly deliver
to the Special Servicer any of the foregoing items received by it with respect
to any Pooled Mortgage Loan, if and to the extent that such items constitute
Additional Special Servicing Compensation. If the Master Servicer shall deposit
in the Collection Account any amount not required to be deposited therein, it
may at any time withdraw such amount from the Collection Account, any provision
herein to the contrary notwithstanding.

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

          (b) The Trustee shall establish and maintain one or more segregated
accounts (or, subject to Section 3.04(h), sub-accounts) (collectively, the

the Distribution Account, any provision herein to the contrary notwithstanding.

          (c) The Trustee shall establish and maintain one or more accounts (or,
subject to Section 3.04(h), sub-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 with respect to the Certificates on such Distribution Date, the
Trustee shall, with respect to each Interest Reserve Loan, withdraw from the

establish and maintain one or more accounts (or, subject to Section 3.04(h),

held in the Excess Liquidation Proceeds Account.

          (e) If any A/B Material Default occurs and is continuing (and, as a
result, the related B-Note Mortgage Loan is being serviced hereunder), or if the
Mortgaged Property securing any A/B Mortgage Loan Pair has become an REO
Property, the Master Servicer shall establish and maintain, or cause to be
established and maintained, a A/B Mortgage Loan Pair Custodial Account, into
which the Master Servicer shall deposit or cause to be deposited on a daily

     Loan Pair Custodial Account by the Master Servicer pursuant to Section 3.06

     Custodial Account by the Master Servicer pursuant to Section 3.06 in

<PAGE>

Crossing Companion Mortgage Loan (or any successor Companion REO Loan with
respect thereto) may also be reimbursed (together with interest thereon) out of
amounts received from the holder of the Great Lakes Crossing Companion Mortgage
Loan as and to the extent contemplated by the Great Lakes Crossing Intercreditor
Agreement. No amounts may be withdrawn from the Collection Account to pay for
the reimbursement of Advances made or deemed made in respect of the Great Lakes

(with interest) from the holder of the Great Lakes Crossing Companion Mortgage
Loan for any Advances made in respect of the Great Lakes Crossing Total Mortgage
Loan or any related REO Property for which it is entitled to reimbursement
pursuant to the Great Lakes Crossing Intercreditor Agreement.

          The Master Servicer may pay itself monthly any Net Investment Earnings

          (g) Funds in the Collection Account, the Distribution Account, the
Interest Reserve Account, the Excess Liquidation Proceeds Account, any A/B

location of the Collection Account and the GLCTML Custodial Account as of the
Closing Date, the location of any A/B Mortgage Loan Pair Custodial Account when
first established and the new location of the Collection Account, the GLCTML
Custodial Account or any A/B Mortgage Loan Pair Custodial Account prior to any

Liquidation Proceeds Account shall each be established at the Corporate Trust
Office of the Trustee, and the Trustee shall give notice to the other parties
hereto of the new location of each of the Distribution Account, Interest Reserve
Account and Excess Liquidation Proceeds Account prior to any change thereof.

          (h) Notwithstanding the foregoing or any other provision to the
contrary in this Agreement, the Master Servicer may maintain the Collection
Account, the GLCTML Custodial Account and the respective A/B Mortgage Loan Pair
Custodial Accounts as multiple separate sub-accounts 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
Collection Account, the GLCTML Custodial Account and the respective A/B Mortgage
Loan Pair Custodial Accounts were maintained as multiple separate accounts; (ii)
all distributions on the Certificates will be calculated and made in the same
manner as would be the case if the Collection Account, the GLCTML Custodial
Account and the respective A/B Mortgage Loan Pair Custodial Accounts were
maintained as multiple separate accounts; (iii) the Master Servicer shall make
credits and debits to those multiple sub-accounts in a manner consistent with
the provisions of this Agreement governing deposits and withdrawals of funds to
and from the Collection Account, the GLCTML Custodial Account and the respective
A/B Mortgage Loan Pair Custodial Accounts, respectively; (iv) the Master
Servicer's maintaining the Collection Account, the GLCTML Custodial Account and
the respective A/B Mortgage Loan Pair Custodial Accounts as multiple separate
sub-accounts of a single Eligible Account (as opposed to in the form of multiple
separate Eligible Accounts) shall not materially and adversely affect any of the
Certificateholders, the holder of the Great Lakes Crossing Companion Mortgage
Loan or any B-Note Mortgage Loan Holder; and (v) such single Eligible Account
shall be entitled "[name of Master Servicer], as Master Servicer, in trust for
the registered holders of Credit Suisse First Boston Mortgage Securities Corp.,

contrary in this Agreement, the Trustee may maintain the Distribution Account,
the Interest Reserve Account and the Excess Liquidation Proceeds Account as

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 will 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

credits and debits to those three sub-accounts in a manner consistent with the
provisions of this Agreement governing deposits and withdrawals of funds to and
from the Distribution Account, the Interest Reserve Account and the Excess
Liquidation Proceeds Account, respectively; (iv) the Trustee's maintaining the
Distribution Account, the Interest Reserve Account and the Excess Liquidation
Proceeds Account as three separate sub-accounts 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 "[name of Trustee], as Trustee, in trust for the
registered holders of Credit Suisse First Boston Mortgage Securities Corp.,

     Section 3.09(c) with respect to any Pooled Mortgage Loan or REO Property
     (other than the costs of environmental testing, which are to be covered by,
     and reimbursable as, a Servicing Advance);

               (xv) to pay itself, the 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, out of such
     general collections on the Pooled Mortgage Loans and any REO Properties as
     are then on deposit in the Collection Account, any amounts payable to any
     such Person pursuant to Section 6.03, Section 7.01(b), Section 8.05(b), or
     Section 8.13, as applicable;

               (xvi) to pay, out of such general collections on the Pooled
     Mortgage Loans and any REO Properties then on deposit in the Collection
     Account, any reasonable out-of-pocket cost or expense (including the
     reasonable fees of tax accountants and attorneys) incurred by the Trustee
     pursuant to Section 3.17(a)(iii) in connection with providing advice to the
     Special Servicer with respect to any REO Property, except to the extent
     that the subject expense relates to the Great Lakes Crossing Companion
     Mortgage Loan or any successor Companion REO Mortgage Loan with respect
     thereto;

               (xvii) to pay itself, the Special Servicer, the Trustee, any
     Fiscal Agent or the Depositor, as the case may be, any amount that is
     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

                                     -140-

<PAGE>

     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, the Special Servicer, Column, KeyBank, the
     Column Performance Guarantor, a Controlling Class Certificateholder or any
     other particular Person, as the case may be, with respect to any Pooled
     Mortgage Loan that was previously purchased or otherwise removed from the
     Trust Fund by such Person pursuant to or as contemplated by this Agreement,
     all amounts received on such Pooled Mortgage Loan subsequent to the date of
     purchase or other removal;

               (xix) to pay amounts (other than customary monthly remittances)
     payable (A) by the holder of the related Pooled A-Note Mortgage Loan to any
     B-Note Mortgage Loan Holder under the related A/B Intercreditor Agreement
     or (B) by the holder of the Great Lakes Crossing Pooled Mortgage Loan to
     the holder of the Great Lakes Crossing Companion Mortgage Loan pursuant to
     the Great Lakes Crossing Intercreditor Agreement;

               (xx) to transfer any Excess Liquidation Proceeds on deposit in
     the Collection Account to the Excess Liquidation Proceeds Account in
     accordance with Section 3.04(d); and

               (xxi) to clear and terminate the Collection Account at the
     termination of this Agreement pursuant to Section 9.01;

provided that no party hereto shall be entitled to payment or reimbursement from
the Collection Account with respect to any Pooled A-Note Mortgage Loan or
related REO Property for which it can be reimbursed out of the related A/B
Mortgage Loan Pair Custodial Account (other than Nonrecoverable Advances and
interest thereon) or with respect to the Great Lakes Crossing Pooled Mortgage
Loan or any successor Pooled REO Loan with respect thereto for which it can be
reimbursed out of the GLCTML Custodial Account (other than Nonrecoverable
Advances and interest thereon).

          If amounts on deposit in the Collection Account at any particular time
(after withdrawing any portion of such amounts deposited in the Collection
Account in error) are insufficient to satisfy all payments, reimbursements and
remittances to be made therefrom as set forth in clauses (ii) through (xx)
above, then the corresponding withdrawals from the Collection Account shall be
made in the following priority and subject to the following rules: (x) if the
payment, reimbursement or remittance is to be made from a specific source of
funds, then such payment, reimbursement or remittance shall be made from that
specific source of funds on a pro rata basis with any and all other payments,
reimbursements and remittances to be made from such specific source of funds;
and (y) if the payment, reimbursement or remittance can be made from any funds
on deposit in the Collection Account, then (following any withdrawals made from
the Collection Account in accordance with the immediately preceding clause (x)
above) such payment, reimbursement or remittance shall be made from the general
funds remaining on deposit in the 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 any reimbursements of Advances in respect of any
particular Pooled Mortgage Loan or Pooled REO Loan out of the Collection Account
pursuant to any of clauses (ii), (vi) and (vii) above, and any payments of
interest thereon out of the Collection Account pursuant to either of clauses
(viii) and (ix) above, shall be made (to the extent of

                                     -141-

<PAGE>

their respective entitlements to such reimbursements and/or payments): first, to
any Fiscal Agent; second, to the Trustee; and third, pro rata, to the Master
Servicer and the Special Servicer.

          The Master Servicer shall keep and maintain separate accounting
records, on a loan-by-loan and property-by-property basis when appropriate, in
connection with any withdrawal from the Collection Account pursuant to any of
clauses (ii) through (xx) above.

          The Master Servicer shall pay to the Special Servicer from the
Collection Account amounts permitted to be paid to the Special Servicer
therefrom promptly upon receipt of a certificate of a Servicing Officer of the
Special Servicer describing the item and amount to which the Special Servicer is
entitled. The Master Servicer may rely conclusively on any such certificate and
shall have no duty to recalculate the amounts stated therein. The Special
Servicer shall keep and maintain separate accounting for each Specially Serviced
Pooled Mortgage Loan and REO Property, on a loan-by-loan and
property-by-property basis, for the purpose of justifying any request thereby
for withdrawal from the Collection Account.

          (b) The Trustee shall, from time to time, make withdrawals from the
Distribution Account for each of the following purposes (the order set forth
below not constituting an order of priority for such withdrawals):

               (i) to make distributions to Certificateholders on each
     Distribution Date pursuant to Section 4.01;

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

               (iii) to pay itself, the Master Servicer, the 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 the Collection Account pursuant
     to Section 3.05;

               (iv) to pay any and all federal, state and local taxes imposed on
     any REMIC Pool or on the assets or transactions of any REMIC Pool, 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;

               (v) 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 protects or is otherwise in furtherance of the rights and
     interests of Certificateholders;

               (vi) to pay for the cost of recording this Agreement pursuant to
     the first sentence of Section 11.02(a);

               (vii) to pay itself any Net Investment Earnings with resect to
     the Distribution Account for any related Investment Period; and

                                     -142-

<PAGE>

               (viii) to clear and terminate the 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
Distribution Account all Interest Reserve Amounts in respect of the Interest
Reserve Loans then on deposit in the Interest Reserve Account. On each
Distribution Date, the Trustee may withdraw from the Interest Reserve Account
and pay itself any Net Investment Earnings with respect to the Interest Reserve
Account for the then most recently ended related Investment 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 of Excess Liquidation Proceeds, 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 Distribution Account, for distribution on such Distribution
Date, any and all amounts then on deposit in the Excess Liquidation Proceeds
Account. On each Distribution Date, the Trustee may withdraw from the Excess
Liquidation Proceeds Account and pay itself any Net Investment Earnings with
respect to the Excess Liquidation Proceeds Account for the then most recently
ended related Investment Period.

          (e) The Trustee, any Fiscal Agent, the Depositor, the Master Servicer
and the Special Servicer, as applicable, shall in all cases have a right prior
to the Certificateholders to any particular funds on deposit in the 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 the Collection Account or the
Distribution Account pursuant to the express terms of this Agreement.

          SECTION 3.06. Investment of Funds in the Collection Account, the
                        Servicing Accounts, the Reserve Accounts, the A/B
                        Mortgage Loan Pair Custodial Accounts, the GLCTML
                        Custodial Account, the Purchase Price Security Deposit
                        Accounts, the Special Reserve Accounts, the REO
                        Account, the Distribution Account, the Interest Reserve
                        Account and the Excess Liquidation Proceeds Account.

          (a) The Master Servicer may direct (pursuant to a standing order or
otherwise) any depositary institution (including the Trustee) maintaining the
Collection Account, the GLCTML Custodial Account or any A/B Mortgage Loan Pair
Custodial Account, Purchase Price Security Deposit Account, Special Reserve
Account, Servicing Account or Reserve Account, and the Special Servicer may
direct (pursuant to a standing order or otherwise) any depositary

                                     -143-

<PAGE>

institution maintaining the REO Account, and the Trustee may direct (pursuant to
a standing order or otherwise) any depositary institution maintaining the
Distribution Account, the Interest Reserve Account or the Excess Liquidation
Proceeds Account, to invest, or if it is such depositary institution, may itself
invest, the funds held therein (each such account, an "Investment Account") 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; 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 any such investment of funds in any Purchase Price Security Deposit Account
or Special Reserve Account shall be subject to the investment directions of the
Responsible Party that caused the establishment of such Investment Account and,
further, to the terms of the related Mortgage Loan Purchase Agreement. All such
Permitted Investments shall be held to maturity, unless payable on demand. Any
investment of funds in an Investment Account shall be made in the name of the
Trustee (in its capacity as such). The Master Servicer (acting on behalf of the
Trustee with respect to Permitted Investments of amounts in the Collection
Account, the GLCTML Custodial Account or any A/B Mortgage Loan Pair Custodial
Account, Purchase Price Security Deposit Account, Special Reserve Account,
Servicing Account or Reserve Account), the Special Servicer (acting on behalf of
the Trustee with respect to Permitted Investments of amounts in the REO
Account), and the Trustee (with respect to Permitted Investments in the
Distribution Account, the Interest Reserve Account or the Excess Liquidation
Proceeds Account), in each such case, 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 the Master Servicer or the Special Servicer 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, then the party hereunder that maintains such Investment
Account, whether such party is the Master Servicer, the Special Servicer or the
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 party that such Permitted Investment would
               not constitute a Permitted Investment in respect of funds
               thereafter on deposit in such Investment Account.

          (b) Whether or not the Master Servicer directs the investment of funds
in the Collection 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 related Investment Period, shall be for the
sole and exclusive benefit of the Master Servicer and shall be subject to its
withdrawal in accordance with Section 3.05(a). Whether or not the Master
Servicer directs the investment of funds in any Servicing Account or Reserve
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

                                     -144-

<PAGE>

related Investment Period, and subject to the requirements of applicable law or
the terms of the related Mortgage Loan(s) regarding the payment of such interest
and investment income to the related Borrower, shall be for the sole and
exclusive benefit of the Master Servicer and shall be subject to withdrawal from
time to time in accordance with Section 3.03. Whether or not the Special
Servicer directs the investment of funds in the REO Account, interest and
investment income realized on funds deposited therein, to the extent of the Net
Investment Earnings, if any, for such Investment Account for each related
Investment Period, shall be for the sole and exclusive benefit of the Special
Servicer and shall be subject to its withdrawal in accordance with Section
3.16(b). Whether or not the Trustee directs the investment of funds in the
Distribution Account, the Interest Reserve Account 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
Investment Account for each related Investment 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), 3.05(c) or 3.05(d), as applicable. If any loss
shall be incurred in respect of any Permitted Investment on deposit in any
Investment Account (exclusive of any Purchase Price Security Deposit Account or
Special Reserve Account), the party hereunder that maintains such Investment
Account, whether such party is the Master Servicer, the Special Servicer or the
Trustee, shall promptly deposit therein from its own funds, without right of
reimbursement, no later than the end of the related Investment Period during
which such loss was incurred, the amount of the Net Investment Loss, if any, in
respect of such Investment Account for such Investment 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. The
distribution of interest and investment income realized on, and the coverage of
losses resulting from the investment of, funds deposited in any Purchase Price
Security Deposit Account or Special Reserve Account shall be governed by the
terms of the applicable Mortgage Loan Purchase Agreement.

          (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 amounts on deposit in any Investment
Account, then the Trustee may (and, subject to Section 8.02, upon the request of
Holders of Certificates entitled to not less than 25% of the Voting Rights
allocated to any Class of REMIC III Regular Interest Certificates, 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, if the default is in respect of a
Permitted Investment of funds in the Collection Account, the GLCTML Custodial
Account or in any A/B Mortgage Loan Pair Custodial Account, Reserve Account or
Servicing Account and if the Master Servicer is in default of its obligations
under Section 3.06(b), or by the Special Servicer, if the default is in respect
of a Permitted Investment of funds in the REO Account and if the Special
Servicer is in default of its obligations under Section 3.06(b). This provision
is in no way intended to limit any actions that the Master Servicer or the
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) In the case of each Mortgage Loan (including each Specially
Serviced Mortgage Loan), subject to the next sentence, the Master Servicer shall
use reasonable efforts consistent with the Servicing Standard to cause the
related Borrower to maintain, and, if such Borrower does not so maintain, the
Master Servicer will itself cause to be maintained, for the related Mortgaged
Property 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 Mortgage Loan grants the lender thereunder any discretion (by way of
consent, approval or otherwise) as to the insurance coverage that the related
Borrower is required to maintain, the 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 Mortgage Loan grants the lender
thereunder any discretion (by way of consent, approval or otherwise) as to the
insurance provider from whom the related borrower is to obtain the requisite
insurance coverage, the Master Servicer shall require the related Borrower to
obtain the requisite 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 Fitch and "A2" 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,
the Master Servicer shall be required to maintain such insurance coverage upon
the related Borrower's failure to do so only to the extent that such insurance
is available at commercially reasonable rates and the Trustee as mortgagee has
an insurable interest. In the case of each Mortgage Loan (including each
Specially Serviced Mortgage Loan), the Master Servicer shall use its reasonable
efforts to cause the related Borrower to maintain, and if the related Borrower
does not so maintain, the Master Servicer shall maintain, all-risk casualty
insurance which does not contain any carve-out for (or, alternatively, a
separate insurance policy that expressly provides coverage for) property damage
resulting from a terrorist or similar act, to the extent not prohibited by the
terms of the related Mortgage Loan Documents; provided that the Master Servicer
shall not be required to call default under a Mortgage Loan if the related
Borrower fails to maintain such insurance, and the Master Servicer shall not be
required to maintain such insurance, if, in each case, the Special Servicer
(subject to Section 3.24(a) and Section 3.27(a)) has determined in accordance
with the Servicing Standard that either (i) such insurance is not available at
commercially reasonable rates and that such hazards are not at the time commonly
insured against for properties similar to the Mortgaged Property and located in
or around the region in which such Mortgaged Property is located or (ii) such
insurance is not available at any rate; and provided, further, that the Master
Servicer (with respect to a Performing Mortgage Loan) or the Special Servicer
(with respect to any Specially Serviced Mortgage Loan) shall use reasonable
efforts, consistent with the Servicing Standard, to enforce any express
provisions in the related Mortgage Loan Documents relating to insurance against
loss or damage resulting from terrorist or similar acts. Subject to Section
3.17(b), the Special Servicer shall also cause to be maintained for each REO
Property no less insurance coverage (to the extent available at commercially
reasonable rates) than was previously required of the related Borrower under the
related Mortgage Loan Documents 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

                                     -146-

<PAGE>

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 Fitch and "A2"
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, if insurance coverage against property damage resulting
from terrorist or similar act is available with respect to any REO Property but
not at a commercially reasonable rate, then the Special Servicer shall still
cause such insurance coverage to be maintained with respect to such REO Property
if such insurance coverage is otherwise commonly obtained with respect to
properties similar to such REO Property and located in or around the area in
which such REO Property is located. All such insurance policies shall contain
(if they insure against loss to property) a "standard" mortgagee clause, with
loss payable to the Master Servicer on behalf of the Trustee (in the case of
insurance maintained in respect of a Mortgage Loan), or shall name the Trustee
as the insured, with loss payable to the Special Servicer on behalf of the
Trustee (in the case of insurance maintained in respect of an REO Property), and
shall be issued by an insurer authorized under applicable law to issue such
insurance. Any amounts collected by the Master Servicer or the Special Servicer
under any such policies (other than amounts to be applied to the restoration or
repair of the related Mortgaged Property or REO Property or amounts to be
released to the related Borrower, in each case in accordance with the Servicing
Standard) shall be deposited in the Collection Account, the GLCTML Custodial
Account or an A/B Mortgage Loan Pair Custodial Account, as applicable in
accordance with Section 3.04, in the case of amounts received in respect of a
Mortgage Loan, or in the REO Account, in the case of amounts received in respect
of an REO Property. Any cost incurred by the Master Servicer or the Special
Servicer in maintaining any such insurance shall not, for purposes hereof,
including calculating monthly distributions to Certificateholders, be added to
the unpaid principal balance or Stated Principal Balance of any related Mortgage
Loan, notwithstanding that the terms of such Mortgage Loan so permit; provided
that this sentence shall not limit the rights of the Master Servicer or the
Special Servicer on behalf of the Trust to enforce any obligations of the
related Borrower under such Mortgage Loan. Costs to the Master Servicer or the
Special Servicer of maintaining insurance policies pursuant to this Section 3.07
shall be paid by and reimbursable to the Master Servicer or the Special
Servicer, as the case may be, as a Servicing Advance.

          (b) If the Master Servicer, in the case of Mortgage Loans, or the
Special Servicer, in the case of REO Properties, 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 such Mortgage Loans or REO
Properties, as applicable, 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 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,
the Master Servicer or the Special Servicer, as the case may be, shall
conclusively be deemed to have satisfied its obligation to cause hazard
insurance to be maintained on the related Mortgaged Properties 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 Master Servicer or the Special Servicer, whichever maintains such policy,
shall, if there shall not have been maintained on any Mortgaged Property or REO
Property, as applicable, 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, from its own funds, the amount not otherwise payable
under the blanket or master

                                     -147-

<PAGE>

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 Pooled 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 Master
Servicer and the Special Servicer shall each prepare and present, on behalf of
itself, the Trustee, the Certificateholders and, if applicable, the related
B-Note Mortgage Loan Holders or the holder of the Great Lakes Crossing Companion
Mortgage Loan, claims under any such blanket or master force placed policy
maintained by it 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
Pooled Mortgage Loans covered by an Environmental Insurance Policy that are
listed on Exhibit C-3 to this Agreement, the Master Servicer shall notify the
insurer under such Environmental Insurance Policy and take all other action
necessary for the Trustee, on behalf of the Certificateholders, to be an insured
(and for the Master Servicer, on behalf of the Trust, to make claims) under such
Environmental Insurance Policy. In the event that the Master Servicer has actual
knowledge of any event (an "Insured Environmental Event") giving rise to a claim
under any Environmental Insurance Policy in respect of any Pooled Mortgage Loan
covered thereby, the Master Servicer shall, in accordance with the terms of such
Environmental Insurance Policy and the Servicing Standard, timely make a claim
thereunder with the appropriate insurer and shall take such other actions in
accordance with the Servicing Standard which are necessary under such
Environmental Insurance Policy in order to realize the full value thereof for
the benefit of the Certificateholders. If any other party hereto has actual
knowledge of an Insured Environmental Event with respect to any Pooled Mortgage
Loan listed on Exhibit C-3 to this Agreement, such party shall promptly so
notify the 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 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 Pooled Mortgage
Loans, the Master Servicer shall review and familiarize itself with the terms
and conditions relating to enforcement of claims and shall monitor the dates by
which any claim must be made or any action must be taken under such policy in
order to realize the full value thereof for the benefit of the
Certificateholders in the event the Master Servicer has actual knowledge of an
Insured Environmental Event giving rise to a claim under such policy.

          In the event that the Master Servicer receives notice of any
termination of any Environmental Insurance Policy that relates to one or more
Pooled Mortgage Loans, the Master Servicer shall, within five (5) Business Days
after receipt of such notice, notify the Special Servicer, the Controlling Class
Representative, the Rating Agencies and the Trustee of such termination in
writing. Upon receipt of such notice, the 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 Master Servicer and shall be reimbursable to it as a Servicing
Advance.

          (d) Each of the Master Servicer and the Special Servicer shall at all
times during the term of this Agreement (or, in the case of the Special
Servicer, at all times during the term of this Agreement during which Specially
Serviced Pooled Mortgage Loans and/or REO Properties exist as part of the Trust
Fund) keep in force with a Qualified Insurer having a financial strength or
claims-paying

                                     -148-

rating no lower than two rating categories below the highest rated Certificates
outstanding, and in any event no lower than "A" from Fitch and "A2" from
Moody's, 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 of the Master Servicer and the
Special Servicer shall be deemed to have complied with the foregoing provision
if an Affiliate thereof has such fidelity bond coverage and, by the terms of
such fidelity bond, the coverage afforded thereunder extends to the Master
Servicer or the Special Servicer, as the case may be. Such fidelity bond shall
provide that it may not be canceled without ten days' prior written notice to
the Trustee.

          Each of the Master Servicer and the Special Servicer shall at all
times during the term of this Agreement (or, in the case of the Special
Servicer, at all times during the term of this Agreement during which Specially
Serviced Pooled Mortgage Loans and/or REO Properties 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 Fitch and "A2"
from Moody's, 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, 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 of the Master Servicer and the Special Servicer shall be deemed
to have complied with the foregoing provisions if an Affiliate thereof has such
insurance and, by the terms of such policy or policies, the coverage afforded
thereunder extends to the Master Servicer or the Special Servicer, as the case
may be. Any such errors and omissions policy shall provide that it may not be
canceled without ten days' prior written notice to the Trustee.

          SECTION 3.08. Enforcement of Alienation Clauses.

          The Master Servicer (with respect to a Performing Mortgage Loan) and
the Special Servicer (with respect to a Specially Serviced Mortgage Loan), on
behalf of the Trustee as the mortgagee of record, shall enforce any
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 Master Servicer or
the Special Servicer, as the case may be, has determined, in its reasonable
judgment, that waiver of such restrictions would be in accordance with the
Servicing Standard; provided that, subject to the related Mortgage Loan
Documents and applicable law, neither the Master Servicer nor the 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 Pooled 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,
if, in the case of Moody's, the affected Pooled Mortgage Loan, individually or
together with all other Pooled Mortgage Loans, if any, that are in the same
Cross-Collateralized Group as such Pooled Mortgage Loan, has a Cut-off Date
Principal Balance in excess of the lesser of $20,000,000 and 2% of the aggregate
Stated Principal Balance of the Mortgage Pool, and, if, in the case of Fitch,
the affected Pooled Mortgage Loan, individually or together with all other
Pooled

                                     -149-

<PAGE>

Mortgage Loans, if any, that are in the same Cross-Collateralized Group as such
Pooled Mortgage Loan, has a Stated Principal Balance in excess of 5% of the then
aggregate Stated Principal Balance of the Mortgage Pool, or is one of the ten
largest Pooled Mortgage Loans based on Stated Principal Balance, then, subject
to the related Mortgage Loan Documents and applicable law, neither the Master
Servicer nor the 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 Pooled Mortgage Loan until it has received
written confirmation from the subject 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 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" or "due-on-encumbrance" clause under any Pooled
Mortgage Loan until it has received the consent of the Special Servicer (which
consent shall be subject to Section 3.24 and shall be deemed granted if not
denied in writing by the Special Servicer within ten (10) Business Days after
its receipt of the Master Servicer's request for such consent along with the
Master Servicer's written recommendation and any additional information the
Special Servicer may reasonably request); and provided, further, that, subject
to the related Mortgage Loan Documents and applicable law, neither the Master
Servicer nor the 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 the
Master Servicer nor the Special Servicer shall be obligated to cover or assume
any such costs or expenses); and provided, further, that neither the Master
Servicer nor the 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. In the case of any Pooled Mortgage Loan, the
Master Servicer and the Special Servicer shall each provide the other with all
such information as each may reasonably request in order to make any
determination required under this paragraph.

          In connection with any permitted assumption of any Mortgage Loan or
waiver of a "due-on-sale" or "due-on-encumbrance" clause thereunder, the Master
Servicer (in the case of a Performing Mortgage Loan) or the Special Servicer (in
the case of a Specially Serviced Mortgage Loan) 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 any other provisions of this Section 3.08, the Master
Servicer (without the consent of the Special Servicer) and the Special Servicer,
as applicable, may grant a Borrower's request for consent to subject the related
Mortgaged Property to an easement or right-of-way for utilities, access,
parking, public improvements or another purpose and may consent to subordination
of the related Mortgage Loan(s) to such easement or right-of-way; provided that
the Master Servicer or Special Servicer, as applicable, shall have determined
(i) in accordance with the Servicing Standard that such easement or right-of-way
will not materially interfere with the then-current use of the related Mortgaged
Property or the security intended to be provided by such Mortgage and will not
materially or adversely affect the value of such Mortgaged Property and (ii)
that no REMIC Pool will fail to qualify as a REMIC as a result thereof and that
no tax on "prohibited transactions" or "contributions" after the Closing Date
would be imposed on any REMIC Pool as a result thereof; and provided, further
that the

                                     -150-

<PAGE>

Master Servicer or the Special Servicer, as applicable, shall cause the Borrower
to pay the costs (including attorneys' fees and expenses) associated with the
determination described in clause (ii).

          If the Master Servicer or the 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 the Master
Servicer or the 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 related Mortgage Loan Documents and the 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 Master
Servicer or the Special Servicer in accordance with Section 3.11. Neither the
Master Servicer nor the 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) The Special Servicer shall, subject to Sections 3.09(b), 3.09(c),
3.09(d) and 3.24, 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 that comes into
and continues in default and as to which no satisfactory arrangements can be
made for collection of delinquent payments, including pursuant to Section 3.20;
provided that the Master Servicer shall not, with respect to any Pooled ARD
Mortgage Loan or the Great Lakes Crossing Companion 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 the Special Servicer may do so with respect to any
Specially Serviced Mortgage Loan that is an ARD Mortgage Loan 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 Special Servicer shall consult Independent counsel
regarding the order and manner in which the 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 Special Servicer as a
Servicing Advance. In addition, all other costs and expenses (including
attorney's fees and expenses) incurred in any foreclosure sale or similar
proceeding shall be paid by, and reimbursable to, the Special Servicer as a
Servicing Advance. Nothing contained in this Section 3.09 shall be construed so
as to require the 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

                                     -151-

<PAGE>

excess of the fair market value of such property, as determined by the 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 the 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,
whether for purposes of bidding at foreclosure or otherwise, the 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). The Master Servicer shall not 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 the 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 any REMIC Pool at any given time constitutes not more than a de
minimis amount of the assets of such REMIC Pool within the meaning of Treasury
regulation 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. In addition, except as permitted under Section 3.17(a), the 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 the Special
     Servicer; or

               (ii) the Special Servicer shall have obtained an Opinion of
     Counsel (the cost of which shall be covered by, and reimbursable 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 any REMIC Pool or an Adverse Grantor Trust Event with respect to
     any Grantor Trust Pool.

          (c) Notwithstanding the foregoing provisions of this Section 3.09, the
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 Mortgage Loan Pair or the Great Lakes Crossing Total Mortgage Loan, the
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable), could, in the reasonable judgment of
the 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) the 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

                                     -152-

<PAGE>

     Assessments and performed during the 12-month period preceding any such
     acquisition of title or other action, that (A) such Mortgaged Property is
     in compliance with applicable environmental laws and regulations and (B)
     there are no circumstances or conditions present at such 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 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, in the case of an A/B Mortgage
     Loan Pair or the Great Lakes Crossing Total Mortgage Loan, the related
     B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
     Companion Mortgage Loan, as applicable) on a present value basis (the
     relevant discounting of anticipated collections that will be distributable
     to Certificateholders, a B-Note Mortgage Loan Holder and/or the holder of
     the Great Lakes Crossing Companion Mortgage Loan, as applicable, 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)(B) above.

          Any such determination by the 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 Master Servicer, the
Controlling Class Representative and, in the case of an A/B Mortgage Loan Pair
or the Great Lakes Crossing Companion Mortgage Loan, any related B-Note Mortgage
Loan Holder or the holder of the Great Lakes Crossing Companion Mortgage Loan,
as applicable, 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 Master Servicer at the direction
of the Special Servicer given in accordance with Section 3.19(b); provided,
however, that the 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 Collection Account pursuant to Section
3.05(a) or, in the case of an A/B Mortgage Loan Pair, subject to the related A/B
Intercreditor Agreement, or the Great Lakes Crossing Total Mortgage Loan,
subject to the Great Lakes Crossing Intercreditor Agreement, out of the related
A/B Mortgage Loan Pair Custodial Account pursuant to Section 3.04(e) or out of
the GLCTML Custodial Account pursuant to Section 3.04(f), as applicable.

          (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 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.

                                     -153-

<PAGE>

          (e) The Special Servicer shall report to the Trustee, the Master
Servicer, the Controlling Class Representative and, in the case of an A/B
Mortgage Loan Pair or the Great Lakes Crossing Companion Mortgage Loan, any
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable, monthly in writing as to any actions
taken by the 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 Pooled Mortgage
Loan's becoming a Corrected Pooled Mortgage Loan.

          (f) The Special Servicer shall have the right to determine, in
accordance with the Servicing Standard, the advisability of seeking to obtain a
deficiency judgment if the state in which the Mortgaged Property is located and
the terms of the subject Mortgage Loan(s) 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, the Special Servicer shall on a timely
basis prepare and forward to the 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, the Special Servicer shall prepare and deliver
to the 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 the Master Servicer. The 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 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 Special Servicer makes a Final Recovery
Determination with respect to any Mortgage Loan or REO Property, it shall
promptly (and in any event, no later than the third Business Day following such
Final Recovery Determination) deliver to the Trustee and the Master Servicer
(with a copy to the Controlling Class Representative and, in the case of an A/B
Mortgage Loan Pair or the Great Lakes Crossing Total Mortgage Loan, to any
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable) an Officer's Certificate setting forth
such Final Recovery Determination and the basis thereof.

          SECTION 3.10. Trustee to Cooperate; Release of Mortgage Files.

          (a) Upon the payment in full of any Mortgage Loan, or the receipt by
the Master Servicer of a notification that payment in full shall be escrowed or
made in a manner customary for such purposes, the 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 the Collection Account, an A/B Mortgage Loan Pair
Custodial

                                     -154-

<PAGE>

Account or the GLCTML Custodial Account, as applicable, pursuant to Section 3.04
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 Master Servicer or its designee and shall
deliver to the 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 the Collection
Account, the GLCTML Custodial Account, any A/B Mortgage 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, the Master Servicer or the Special Servicer
shall otherwise require any Mortgage File (or any portion thereof), then, upon
request of the Master Servicer and receipt from the Master Servicer of a Request
for Release in the form of Exhibit D-1 attached hereto signed by a Servicing
Officer thereof, or upon request of the Special Servicer and receipt from the
Special Servicer of a Request for Release in the form of Exhibit D-2 attached
hereto, the Trustee shall release, or cause any related Custodian to release,
such Mortgage File (or portion thereof) to the Master Servicer or the Special
Servicer, as the case may be, or its designee. Upon return of such Mortgage File
(or portion thereof) to the Trustee or the related Custodian, or upon the
Special Servicer's delivery to the Trustee of an Officer's Certificate stating
that (i) such Mortgage Loan was liquidated and all amounts received or to be
received in connection with such liquidation that are required to be deposited
into the Collection Account, an A/B Mortgage Loan Pair Custodial Account or the
GLCTML Custodial Account, as applicable, pursuant to Section 3.04 have been or
will be so deposited or (ii) such Mortgage Loan has become an REO Property, a
copy of the Request for Release shall be returned by the Trustee to the Master
Servicer or the Special Servicer, as appropriate.

          (c) Within five (5) Business Days of the Special Servicer's request
therefor (or, if the 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 the Special Servicer, in the form supplied
to the Trustee by the 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
to obtain judgment against any Borrower on a Mortgage Note or Mortgage or to
obtain a deficiency judgment, or to enforce any other remedies or rights
provided by a 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 Master Servicer or the Special Servicer; provided that the Trustee may
alternatively execute and deliver to the Special Servicer, in the form supplied
to the Trustee by the Special Servicer, a limited power of attorney issued in
favor of the Special Servicer and empowering the Special Servicer to execute and
deliver any or all of such pleadings or documents relating to any Mortgage Loan
on behalf of the Trustee (however, the Trustee shall not be liable for any
misuse of such power of attorney by the Special Servicer). Together with such
pleadings or documents (or such power of attorney empowering the Special
Servicer to execute the same on behalf of the Trustee), the Special Servicer
shall deliver to the Trustee an Officer's Certificate requesting that such
pleadings or documents (or such power of attorney empowering the 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 the Special
Servicer on behalf of the Trustee) will not invalidate or otherwise affect the

          (d) From time to time as is appropriate for servicing or foreclosure
of any B-Note Mortgage Loan, the Master Servicer or Special Servicer, as
applicable, subject to the related A/B Intercreditor Agreement, shall request
the original of the related Mortgage Note from the related B-Note Mortgage Loan
Holder.

          (e) From time to time as is appropriate for servicing or foreclosure

Special Servicer, as applicable, subject to the Great Lakes Crossing
Intercreditor Agreement, shall request the original of the related Mortgage Note
from the holder of the Great Lakes Crossing Companion Mortgage Loan.

          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, the Master Servicer
shall be entitled to receive the Master Servicing Fee with respect to each
Pooled Mortgage Loan (including each Specially Serviced Mortgage Loan), the
Great Lakes Crossing Companion Mortgage Loan and each REO Loan. As to each such
Mortgage Loan and REO Loan, the Master Servicing Fee shall accrue at the related
Master Servicing Fee Rate (in accordance with the same terms of the related
Mortgage Note as are applicable to the accrual of interest at the Mortgage Rate)
and shall be computed on the basis of the same principal amount as interest
accrues from time to time on such Mortgage Loan or is deemed to accrue from time
to time on such REO Loan, as the case may be, and for the same period respecting
which any related interest payment due on such Mortgage Loan or deemed due on
such REO Loan, as the case may be, is computed. The Master Servicing Fee with
respect to any Pooled Mortgage Loan, the Great Lakes Crossing Companion Mortgage
Loan or any Pooled REO Loan shall cease to accrue if a Liquidation Event occurs
in respect thereof. Master Servicing Fees earned with respect to any Pooled
Mortgage Loan, the Great Lakes Crossing Companion Mortgage Loan or any REO Loan
shall be payable monthly from payments of interest on such Mortgage Loan or REO
Revenues allocable as interest on such REO Loan, as the case may be. The Master
Servicer, on behalf of itself and the holder of the Excess Servicing Strip,
shall be entitled to recover unpaid Master Servicing Fees in respect of any
Pooled Mortgage Loan, the Great Lakes Crossing Companion Mortgage Loan or any
REO Loan out of the portion of any related Insurance Proceeds, Condemnation
Proceeds or Liquidation Proceeds allocable as interest on such Mortgage Loan or
REO Loan, as the case may be.

          The Master Servicer's right to receive the Master Servicing Fee may
not be transferred in whole or in part except in connection with the transfer of
all of the Master Servicer's responsibilities and obligations under this
Agreement and except as otherwise expressly provided herein.

          Without limiting its rights under any other agreement or arrangement,
the Master Servicer shall not be paid any Master Servicing Fee or comparable fee
under this Agreement with respect to any B-Note Mortgage Loan.

          Notwithstanding anything herein to the contrary, KRECM (and its
successors and assigns) may at its option assign or pledge to any third party or
retain for itself the Excess Servicing Strip (in whole but not in part);
provided that any assignee or pledgee of the Excess Servicing Strip must be a
Qualified Institutional Buyer or Institutional Accredited Investor (other than a
Plan); and provided, further, that no transfer, sale, pledge or other assignment
of the Excess Servicing Strip shall be made

                                     -156-

<PAGE>

unless 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; and provided, further, that in
the event of any resignation or termination of KRECM, all or any portion of the
Excess Servicing Strip may, to protect REMIC I against an associated increase in
expenses, be reduced by the Trustee to the extent reasonably necessary (in the
sole discretion of the Trustee) for the Trustee to obtain a qualified successor
Master Servicer (which successor may include the Trustee) that meets the
requirements of Sections 6.04 and 7.02 and that requires market rate servicing
compensation that, in the case of each Pooled Mortgage Loan and Pooled REO Loan,
accrues at a per annum rate greater than the excess of the related Master
Servicing Fee Rate over the then related Excess Servicing Fee Rate. KRECM and
each holder of the Excess Servicing Strip desiring to effect a transfer, sale,
pledge or other assignment of the Excess Servicing Strip shall, and KRECM hereby
agrees, and each such holder of the Excess Servicing Strip by its acceptance of
the Excess Servicing Strip shall be deemed to have agreed, in connection with
any transfer of the Excess Servicing Strip effected by such Person, to indemnify
the Certificateholders, the Trust, the Depositor, the Underwriters, the Trustee,
the Master Servicer, the Certificate Registrar and the Special Servicer 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 the Excess Servicing Strip, 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 Servicer confidential (except as
permitted pursuant to clause (iii) below or, in the case of the Master Servicer,
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 the Excess
Servicing Strip 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 the Excess Servicing Strip 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 the Excess Servicing Strip 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 the Excess Servicing Strip, the Person then acting as the Master Servicer
shall pay, out of each amount paid to such Master Servicer as Master Servicing
Fees with respect to any Pooled Mortgage Loan or Pooled REO Loan, as the case
may be, the portion of the Excess Servicing Strip attributable to such Pooled
Mortgage Loan or Pooled REO Loan to the holder of the Excess Servicing Strip
within one Business Day following the payment of such Master Servicing Fees to
the Master Servicer, in each case in accordance with payment instructions
provided by such holder in writing to the Master Servicer. The holder of the
Excess Servicing Strip shall not have any rights under this Agreement except as
set forth in the preceding sentences of this

                                     -157-

<PAGE>

paragraph. The Master Servicer shall pay the Excess Servicing Strip to the
holder of the Excess Servicing Strip (i.e., KRECM or any such third party) at
such time and to the extent the Master Servicer is entitled to receive payment
of its Master Servicing Fees hereunder, notwithstanding any resignation or
termination of KRECM hereunder (subject to reduction pursuant to the first
sentence of this paragraph).

          (b) Subject to the last paragraph of this Section 3.11(b), the Master
Servicer shall be entitled to receive the following items as additional
servicing compensation (the following items, collectively, "Additional Master
Servicing Compensation"):

               (i) any and all Net Default Charges accrued 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, waiver
     fees, fees paid in connection with defeasance and earn-out fees actually
     paid by a Borrower with respect to a Performing Mortgage Loan;

               (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 each Pooled Mortgage Loan, including a Specially Serviced Pooled
     Mortgage Loan; and

               (v) interest or other income earned on deposits in the Investment
     Accounts (other than any Purchase Price Security Deposit Account or Special
     Reserve Account) maintained by the 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 related
     Investment 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).

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

          Notwithstanding the foregoing, but without limiting its rights under
any other agreement or arrangement, the Master Servicer shall not be paid any
compensation under this Agreement of the type described in clauses (i) through
(iv) of the second preceding paragraph with respect to the B-Note Mortgage
Loans.

          (c) As compensation for its activities hereunder, the Special Servicer
shall be entitled to receive monthly the Special Servicing Fee with respect to
each Specially Serviced Pooled Mortgage Loan and each Pooled REO Loan. As to
each Specially Serviced Pooled Mortgage Loan and Pooled REO Loan, the Special
Servicing Fee shall accrue at the Special Servicing Fee Rate (in accordance with
the same terms of the related Mortgage Note as are applicable to the accrual of
interest at the Mortgage Rate) and shall be computed on the basis of the same
principal amount as interest accrues from time to

                                     -158-

<PAGE>

time on such Specially Serviced Pooled Mortgage Loan or is deemed to accrue from
time to time on such Pooled REO Loan, as the case may be, and for the same
period respecting which any related interest payment due on such Specially
Serviced Pooled Mortgage Loan or deemed to be due on such Pooled REO Loan is
computed. The Special Servicing Fee with respect to any Specially Serviced
Pooled Mortgage Loan or Pooled REO Loan shall cease to accrue as of the date a
Liquidation Event occurs in respect thereof or, in the case of a Specially
Serviced Pooled Mortgage Loan, as of the date it becomes a Corrected Pooled
Mortgage Loan. Earned but unpaid Special Servicing Fees in respect of any
Specially Serviced Pooled Mortgage Loan or Pooled REO Loan shall be payable
monthly out of general collections on the Pooled Mortgage Loans and any REO
Properties on deposit in the Collection Account pursuant to Section 3.05(a).

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

<PAGE>

          As further compensation for its activities hereunder, the Special
Servicer shall also be entitled to receive a Liquidation Fee with respect to
each Specially Serviced Pooled Mortgage Loan or REO Property as to which it
receives any full, partial or discounted payoff from the related Borrower or any
Condemnation Proceeds or Liquidation Proceeds (other than in connection with the
purchase of any such Specially Serviced Pooled Mortgage Loan by the Special
Servicer or the Majority Controlling Class Certificateholder pursuant to Section
3.18; the purchase of any such Specially Serviced Pooled Mortgage Loan or REO
Property by the Master Servicer, the Special Servicer or any
Certificateholder(s) of the Controlling Class pursuant to Section 9.01; the
acquisition of any such Specially Serviced Pooled Mortgage Loan or REO Property
by the Sole Certificateholder(s) in exchange for all the Certificates pursuant
to Section 9.01; the repurchase or replacement 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 Material Document Defect, of any
such Specially Serviced Pooled Mortgage Loan or REO Property by Column or
KeyBank pursuant to a Mortgage Loan Purchase Agreement or by the Column
Performance Guarantor pursuant to the Column Performance Guarantee; the
repurchase of any such Specially Serviced Pooled Mortgage Loan that is an
Exhibit B-5 Mortgage Loan by Column or KeyBank, as applicable, pursuant to a
Mortgage Loan Purchase Agreement, in connection with an Early Defeasance; the
purchase of the Great Lakes Crossing Pooled Mortgage Loan by the holder of the
Great Lakes Crossing Companion Mortgage Loan pursuant to the terms of the Great
Lakes Crossing Intercreditor Agreement; the purchase of the Great Lakes Crossing
Pooled Mortgage Loan by the Class GLC Directing Certificateholder pursuant to
Section 3.27; the purchase of the Ritz-Carlton Key Biscayne Pooled Mortgage Loan
by the Class RCKB Directing Certificateholder pursuant to Section 3.27; the
purchase of any such Specially Serviced Pooled Mortgage Loan that is a Pooled
A-Note Mortgage Loan by the related B-Note Mortgage Loan Holder pursuant to the
related A/B Intercreditor Agreement; or the purchase of any such Specially
Serviced Pooled Mortgage Loan by any related Mezzanine Loan Holder pursuant to
any related Mezzanine Loan Intercreditor Agreement). 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).
The Liquidation Fee with respect to any such Specially Serviced Pooled Mortgage
Loan will not be payable if such Pooled Mortgage Loan becomes a Corrected Pooled
Mortgage Loan. Notwithstanding anything herein to the contrary, no Liquidation
Fee will be payable in connection with the receipt of, or out of, Liquidation
Proceeds collected as a result of the purchase or substitution of any Specially
Serviced Pooled Mortgage Loan or REO Property described in the parenthetical to
the first sentence of this paragraph.

          The Special Servicer's right to receive the Special Servicing Fee, the
Work-out Fee and/or the Liquidation Fee may not be transferred in whole or in
part except in connection with the transfer of all of the Special Servicer's
responsibilities and obligations under this Agreement and except as otherwise
expressly provided herein. In addition, notwithstanding the foregoing provisions
of this Section 3.11(c), Special Servicing Fees, Work-out Fees and Liquidation
Fees earned with respect to any Pooled A-Note Mortgage Loan, any successor
Pooled REO Loan with respect thereto or any related REO Property shall be
payable out of the related A/B Mortgage Loan Pair Custodial Account, to the
maximum extent permitted by the related A/B Intercreditor Agreement, before
being paid out of the Collection Account. Furthermore, notwithstanding the
foregoing provisions of this Section 3.11(c), Special Servicing Fees, Work-out
Fees and Liquidation Fees earned with respect to the Great Lakes Crossing Pooled
Mortgage Loan or any successor Pooled REO Loan with respect thereto shall be

                                     -160-

<PAGE>

payable out of the GLCTML Custodial Account, to the maximum extent permitted by
the Great Lakes Crossing Intercreditor Agreement, before being paid out of the
Collection Account.

          The Special Servicer shall be entitled to such compensation with
respect to the B-Note Mortgage 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 Pooled A-Note Mortgage Loan.

          If and to the extent applicable under the circumstances, the Special
Servicer shall be entitled to a Special Servicing Fee, a Work-out Fee and/or a
Liquidation Fee with respect to the Great Lakes Crossing Companion Mortgage Loan
or any successor Companion REO Loan as if such Mortgage Loan was a Pooled
Mortgage Loan or such REO Loan was a Pooled REO Loan; provided that any such
fees shall be paid hereunder solely out of collections on or in respect of the
Great Lakes Crossing Companion Mortgage Loan or any successor Companion REO Loan
with respect thereto and, in no event, out of the Trust Fund.

          (d) Subject to the last paragraph of this Section 3.11(e), the 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 accrued with respect to a
     Specially Serviced Mortgage Loan or a REO Loan;

               (ii) any and all Net Assumption Fees, Net Assumption Application
     Fees, modification fees, extension fees, consent fees, waiver fees, fees
     paid in connection with defeasance, 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 Loan;

               (iii) 50% of any and all Net Assumption Fees, Net Assumption
     Application Fees, modification fees, extension fees, consent fees, waiver
     fees, fees paid in connection with defeasance 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 the REO
     Account, in accordance with Section 3.06(b) (but only to the extent of the
     Net Investment Earnings, if any, with respect to the REO Account for each
     related Investment Period).

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

          Notwithstanding the foregoing, the Special Servicer shall be entitled
to the amounts described in clauses (i) through (iii) of the second preceding
paragraph that are received with respect to the B-Note Mortgage Loans only as
and to the extent 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
Pooled A-Note Mortgage Loan.

                                     -161-

<PAGE>

          (e) Each of the Master Servicer and the 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 the
Collection Account, the REO Account, any A/B Mortgage Loan Pair Custodial
Account, the GLCTML Custodial Account, Purchase Price Security Deposit Account,
Special Reserve Account, Servicing Account or Reserve Account, and neither the
Master Servicer nor the Special Servicer shall be entitled to reimbursement for
any such expense incurred by it except as expressly provided in this Agreement.
If the Master Servicer is required to make any Servicing Advance hereunder at
the discretion of the Special Servicer in accordance with Section 3.19 or
otherwise, the Special Servicer shall promptly provide the Master Servicer with
such documentation regarding the subject Servicing Advance as the Master
Servicer may reasonably request.

          (f) If the Master Servicer or the Special Servicer is required under
this Agreement to make a Servicing Advance, but it 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 Master Servicer or the
Special Servicer, as the case may be, give notice of such failure to the
defaulting party. If such Advance is not made by the Master Servicer or the
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) The Master Servicer, the 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. Subject to the next sentence and the last sentence of this
Section 3.11(g), such interest with respect to any Servicing Advances made with
respect to or allocable to the Mortgage Pool shall be payable: (i) first, in
accordance with Sections 3.05 and/or 3.26, out of any Default Charges
subsequently collected on or in respect of the particular Pooled Mortgage Loan
or Pooled REO 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 Pooled Mortgage Loans and any REO Properties on
deposit in the Collection Account. Such interest with respect to any Servicing
Advances made with respect to the Great Lakes Crossing Companion Mortgage Loan
or any successor Companion Mortgage Loan with respect thereto shall be payable:
(i) first, in accordance with Section 3.05, out of any Default Charges
subsequently collected on or in respect of such Mortgage Loan or REO Loan, as
the case may be; 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 any other collections on such Mortgage Loan or REO
Loan, as the case may be, on deposit in the GLCTML Custodial Account (but in no
event out of the Trust Fund); provided that this provision is in no way intended
to limit any rights that the Master Servicer, the Special Servicer, the Trustee
or the Fiscal Agent may have to receive payment for such Advance Interest from
the holder of the Great Lakes Crossing Companion Mortgage Loan under the Great
Lakes Crossing Intercreditor Agreement. The Master Servicer shall reimburse
itself, the 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 soon as practicable after funds available

                                     -162-

<PAGE>

for such purpose are deposited in the Collection Account or, if applicable, the
GLCTML Custodial Account or any related A/B Mortgage Loan Pair Custodial
Account. The Master Servicer shall not be entitled to Advance Interest on any
Servicing Advance made thereby to the extent a payment that may be applied to
reimburse such Servicing Advance is received but is being held by or on behalf
of the Master Servicer in suspense. In addition, notwithstanding the foregoing
provisions of this Section 3.11(g), Advance Interest earned on any Advances made
with respect to either Mortgage Loan of an A/B Mortgage Loan Pair or with
respect to any REO Property related to an A/B Mortgage Loan Pair shall be
payable out of the related A/B Mortgage Loan Pair Custodial Account, to the
maximum extent permitted by the related A/B Intercreditor Agreement, before
being paid out of general collections on the Mortgage Pool on deposit in the
Collection Account.

          (h) Notwithstanding anything to the contrary set forth herein, none of
the Master Servicer, the Special Servicer, 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 the Master Servicer, the Special Servicer, the Trustee or any Fiscal Agent,
as the case may be, that it has made (or, in the case of a determination made by
the Special Servicer, that the Master Servicer has made) a Nonrecoverable
Servicing Advance or that any proposed Servicing Advance, if made, would
constitute a Nonrecoverable Servicing Advance, shall be evidenced by an
Officer's Certificate delivered (i) to the Trustee and the Depositor, in the
case of the Master Servicer, (ii) to the Master Servicer and the Trustee in the
case of the Special Servicer, (iii) to the Depositor and the Master Servicer, in
the case of the Trustee or any Fiscal Agent, and (iv) and in each case, to the
Controlling Class Representative, the Class RCKB Directing Certificateholder (if
the Ritz-Carlton Key Biscayne Pooled Mortgage Loan or any related REO Property
is involved), and the Class GLC Directing Certificateholder and the holder of
the Great Lakes Crossing Companion Mortgage Loan (if the Great Lakes Crossing
Total Mortgage Loan or any related Pooled REO Loan is involved). The Officer's
Certificate shall set forth such determination of nonrecoverability and the
considerations of the Master Servicer, the Special Servicer or the Trustee, as
applicable, forming the basis of such determination (which shall include but
shall not be limited to information, to the extent available, such as related
income and expense statements, rent rolls, occupancy status and property
inspections, and shall include an Appraisal (provided that if an Appraisal has
been obtained within the past 12 months, no new Appraisal is required) of the
related Mortgaged Property, the cost of which Appraisal shall be advanced by the
Master Servicer as a Nonrecoverable Servicing Advance). Such Officer's
Certificate shall be accompanied by the Appraisal and all other supporting
documentation relevant to the subject parties' nonrecoverability determination.
The Trustee and any Fiscal Agent will be entitled to conclusively rely on the
Master Servicer's determination that a Servicing Advance is nonrecoverable. The
Master Servicer, the Trustee and any Fiscal Agent shall be entitled to
conclusively rely on the Special Servicer's determination that a Servicing
Advance is a Nonrecoverable Servicing Advance.

          (i) Notwithstanding anything to the contrary set forth herein, the
Master Servicer may (and, at the direction of the Special Servicer if a
Specially Serviced Mortgage Loan or an REO Property is involved, shall) pay
directly out of the Collection Account any servicing expense that, if paid by
the Master Servicer or the Special Servicer, would constitute a Nonrecoverable
Servicing Advance for the subject Mortgage Loan or REO Property; provided that
the Master Servicer (or the 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 and the Trustee, which shall
provide a copy thereof to the Controlling Class

                                     -163-

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 the Master Servicer shall also be delivered promptly to the
Special Servicer, and a copy of any such Officer's Certificate (and accompanying
information) of the Special Servicer shall also be promptly delivered to the
Master Servicer.

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

          (a) The 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 Pooled Mortgage Loan becomes a
Specially Serviced Pooled Mortgage Loan (and, in cases where the related Pooled
Mortgage Loan has become a Specially Serviced Pooled Mortgage Loan, the 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 Pooled Mortgage Loan remains a Specially
Serviced Pooled Mortgage Loan or if such Mortgaged Property becomes an REO
Property); provided that the 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. Beginning in 2004, the Master
Servicer shall at its expense perform or cause to be performed an inspection of
each Mortgaged Property at least once per calendar year (or, if the related
Pooled Mortgage Loan has an unpaid principal balance of under $2,000,000, once
every two years), if the Special Servicer has not already done so during that
period pursuant to the preceding sentence. The Master Servicer and the Special
Servicer shall each prepare (and, promptly following preparation, if there has
been a material adverse change in the condition of the subject Mortgaged
Property or REO Property, as applicable, deliver to the Controlling Class
Representative, the Class GLC Directing Certificateholder and the holder of the
Great Lakes Crossing Companion Mortgage Loan (if the subject Mortgaged Property
is the Great Lakes Crossing Mortgaged Property) and to the Class RCKB Directing
Certificateholder (if the subject Mortgaged Property is the Ritz-Carlton Key
Biscayne Mortgaged Property) a written report 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 the
Master Servicer or the Special Servicer, as applicable, is aware, (ii) any
change in the condition or occupancy of the subject Mortgaged Property of which
the Master Servicer or the 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 the Master Servicer or the
Special Servicer, as the case may be, is aware and that it considers, in
accordance with the Servicing Standard, material. Each of the Master Servicer
and Special Servicer shall, upon request, deliver to the Trustee, to the
Controlling Class Representative, to the Class GLC Directing Certificateholder
and the holder of the Great Lakes Crossing Companion Mortgage Loan (if the
subject Mortgaged Property is the Great Lakes Crossing Mortgaged Property) and
to the Class RCKB Directing Certificateholder (if the subject Mortgaged Property
is the Ritz-Carlton Key Biscayne Mortgaged Property) a copy (or image in
suitable electronic media) of each such written report prepared by it, in each
case within 30 days following the request (or, if later, within 30 days
following the later of completion of the related inspection if the inspection is
performed by the Master Servicer or the 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 the Master Servicer
or the Special Servicer, as applicable, and, to the extent such items have been
delivered to the Trustee by the Master Servicer or the Special Servicer, as
applicable, deliver to each of the Depositor,

                                     -164-

<PAGE>

the Controlling Class Representative, the holder of the Great Lakes Crossing
Companion Mortgage Loan or the Class GLC Directing Certificateholder (in the
case of the Great Lakes Crossing Mortgaged Property), the Class RCKB Directing
Certificateholder (in the case of the Ritz-Carlton Key Biscayne Mortgaged
Property), any Certificateholder 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 the Master Servicer or the Special Servicer.

          (b) Commencing with respect to the calendar quarter ended March 31,
2003, the Special Servicer, in the case of any Specially Serviced Mortgage Loan,
and the Master Servicer, in the case of each Performing Mortgage Loan, shall
make reasonable efforts to collect promptly from each related Borrower quarterly
and annual operating statements, budgets and 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 pursuant to the terms of the
related Mortgage. In addition, the 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. The Special Servicer shall deliver copies (or images in
suitable electronic media) of all of the foregoing items so collected or
obtained by it to the Master Servicer within 30 days of its receipt thereof.

          The Master Servicer shall maintain a CMSA Operating Statement Analysis
Report with respect to each Mortgaged Property and REO Property. Within 60 days
after receipt by the Master Servicer from the related Borrower or otherwise, as
to a Performing Pooled Mortgage Loan, and within 30 days after receipt by the
Master Servicer from the Special Servicer or otherwise, as to a Specially
Serviced Pooled Mortgage Loan or an REO Property, of any annual operating
statements or rent rolls with respect to any Mortgaged Property or REO Property,
the Master Servicer shall, based upon such operating statements or rent rolls,
prepare (or, if previously prepared, update) the CMSA Operating Statement
Analysis Report for the subject Mortgaged Property or REO Property. The Master
Servicer shall remit 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, the underlying operating
statements and rent rolls, to the Trustee and the Special Servicer in a format
reasonably acceptable to the Trustee, the Master Servicer and the Special
Servicer. The Trustee shall, upon request, request from the Master Servicer (if
necessary) and, to the extent such items have been delivered to the Trustee by
the Master Servicer, deliver to the Controlling Class Representative, 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 rent rolls.

          Within 60 days (or, in the case of items received from the Special
Servicer with respect to Specially Serviced Pooled Mortgage Loans and REO
Properties, 30 days) after receipt by the Master Servicer of any quarterly or
annual operating statements with respect to any Mortgaged Property or REO
Property, the Master Servicer shall prepare or update and forward to the
Trustee, the Special Servicer and the Controlling Class Representative (in an
electronic format reasonably acceptable to the Trustee, the Master Servicer and
the Special Servicer) a CMSA NOI Adjustment Worksheet for such Mortgaged
Property or REO Property, together with, if so requested, the related quarterly
or annual operating statements.

                                     -165-

<PAGE>

          If, with respect to any Performing Pooled Mortgage Loan, the Special
Servicer has any questions for the related Borrower based upon the information
received by the Special Servicer pursuant to Section 3.12(a) or 3.12(b), the
Master Servicer shall, in this regard and without otherwise changing or
modifying its duties hereunder, reasonably cooperate with the Special Servicer
in assisting the 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, the Special Servicer shall
prepare and deliver or cause to be delivered to the Master Servicer and the
Controlling Class Representative the following reports (or data files relating
to reports of the Master Servicer) with respect to the Specially Serviced Pooled
Mortgage Loans and REO Properties, providing the required information as of such
Determination Date: (i) a CMSA Property File; and (ii) a CMSA Loan Periodic
Update File (which, in each case, if applicable, will identify each subject
Pooled Mortgage Loan 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, the Special Servicer shall prepare and deliver or cause to be delivered to
the Master Servicer the following reports or the related data fields reflected
in the reports reasonably requested with respect to the Specially Serviced
Pooled Mortgage Loans and any REO Properties, providing the required information
as of such Determination Date: (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 and Corrected Mortgage Loan
Report; and (v) a CMSA REO Status Report. In addition, the Special Servicer
shall from time to time provide the Master Servicer with such information in the
Special Servicer's possession regarding any Specially Serviced Pooled Mortgage
Loan or REO Property as may be requested by the Master Servicer and is
reasonably necessary for the Master Servicer to prepare each report and any
supplemental information required to be provided by the Master Servicer to the
Trustee.

          (d) Not later than 3:00 p.m. (New York City time) on the second
Business Day following each Determination Date, the Master Servicer shall
prepare (if and to the extent necessary) and deliver or cause to be delivered to
the Trustee, in a computer-readable medium downloadable by the Trustee (or, at
the Trustee's written request, in such other form reasonably acceptable to the
recipient, 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, the CMSA Loan Setup File and the
CMSA Loan Periodic Update File), in each case providing the most recent
information with respect to the Pooled Mortgage Loans and any REO Properties as
of the related Determination Date (and which, in each case, if applicable, will
identify each subject Pooled Mortgage Loan by loan number and property name);
provided that the 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 Determination
Date.

          The 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 Pooled Mortgage Loans and any REO Properties, available each
month on the Master Servicer's internet website only with the use of a password,
in which case the 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 and the Controlling Class Representative, and (iii) each
Certificateholder and Certificate Owner who requests such

                                     -166-

<PAGE>

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 Master Servicer). In connection with
providing access to its internet website, the 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 the 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 the
Master Servicer for any liability or damage that may arise therefrom.

          The Master Servicer shall on a monthly basis (in such format and at
such times as the Controlling Class Representative may reasonably designate)
deliver to the Controlling Class Representative the Payments Received after
Determination Date Report and the Special Reconciliation Report.

          (e) The Special Servicer shall deliver to the Master Servicer the
reports set forth in Section 3.12(b) and Section 3.12(c), and the Master
Servicer shall deliver to the Trustee the reports set forth in Section 3.12(d),
in an electronic format reasonably acceptable to the Special Servicer, the
Master Servicer and the Trustee. The Master Servicer may, absent manifest error,
conclusively rely on the reports to be provided by the Special Servicer pursuant
to Section 3.12(b) and Section 3.12(c). The Trustee may, absent manifest error,
conclusively rely on the reports to be provided by the Master Servicer pursuant
to Section 3.12(d). In the case of information or reports to be furnished by the
Master Servicer to the Trustee pursuant to Section 3.12(d), to the extent that
such information or reports are, in turn, based on information or reports to be
provided by the Special Servicer pursuant to Section 3.12(b) or Section 3.12(c)
or to the extent that such reports are to be prepared and delivered by the
Special Servicer pursuant to Section 3.12(b) or Section 3.12(c), the Master
Servicer shall have no obligation to provide such information or reports to the
Trustee until it has received the requisite information or reports from the
Special Servicer, and the Master Servicer shall not be in default hereunder due
to a delay in providing the reports required by Section 3.12(d) caused by the
Special Servicer's failure to timely provide any information or report required
under Section 3.12(b) or Section 3.12(c) of this Agreement.

          (f) Notwithstanding the foregoing, however, the failure of the Master
Servicer or the 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 the Master Servicer or the Special Servicer so fails
because such disclosure, in the reasonable belief of the Master Servicer or the
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
Servicer and the Special Servicer 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. The Master Servicer or the 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) If the Master Servicer or the Special Servicer is required to
deliver any statement, report or information under any provision of this
Agreement, then the Master Servicer or the Special Servicer, as the case may be,
may satisfy such obligation by (x) physically delivering a paper copy of

                                     -167-

<PAGE>

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 the 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, unless the Trustee consents
otherwise, clause (z) shall not apply to the delivery of any information
required to be delivered to the Trustee.

          (h) The Master Servicer and the Special Servicer each shall, with the
reasonable cooperation of the other parties hereto, deliver to each B-Note
Mortgage Loan Holder all documents, statements, reports and information with
respect to the related B-Note Mortgage Loan and/or the related Mortgaged
Property as may be required under the related A/B Intercreditor Agreement.

          (i) The Master Servicer, the Special Servicer and the Trustee shall
forward or otherwise make available to the Class GLC Directing Certificateholder
all such reports, documents and other information (whether pursuant to this
Section 3.12 or otherwise) that the Master Servicer, the Special Servicer or the
Trustee, as the case may be, forwards or otherwise makes available to the
Controlling Class Representative with respect to the Great Lakes Crossing Pooled
Mortgage Loan or any related REO Property, on a concurrent basis.

          (j) The Master Servicer, the Special Servicer and the Trustee shall
forward or otherwise make available to the Class RCKB Directing
Certificateholder all such reports, documents and other information (whether
pursuant to this Section 3.12 or otherwise) that the Master Servicer, the
Special Servicer or the Trustee, as the case may be, forwards or otherwise makes
available to the Controlling Class Representative with respect to the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan or any related REO Property, on a
concurrent basis.

          (k) The Special Servicer shall prepare and deliver to the Master
Servicer, and the Master Servicer shall prepare, if necessary, and deliver to
the holder of the Great Lakes Crossing Companion Mortgage Loan, with respect to
the Great Lakes Crossing Companion Mortgage Loan or any related REO Property,
all of the same type of reports, documents and other information (whether
pursuant to this Section 3.12 or otherwise) that the Special Servicer or the
Master Servicer, as the case may be, is required to prepare and deliver to the
Master Servicer, in the case of the Special Servicer, or to the Trustee, in the
case of the Master Servicer, with respect to the Great Lakes Crossing Pooled
Mortgage Loan or any related REO Property, on a concurrent basis.

          (l) Notwithstanding the foregoing, because the Master Servicer will
not receive the Servicing Files until 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 the Master Servicer in May 2003 will be based solely
upon information generated from actual collections received by the Master
Servicer and from information the Depositor delivers or causes to be delivered
to the Master Servicer (including but not limited to information prepared by
third-party servicers of the Pooled Mortgage Loans and the Great Lakes Crossing
Companion Mortgage Loan with respect to the period prior to the Closing Date).
The Special Servicer shall from time to time (and, in any event, upon request)
provide the Master Servicer with such information in its possession regarding
the Specially Serviced Mortgage Loans and REO Properties as

                                     -168-

<PAGE>

may be necessary for the Master Servicer to prepare each report and any
supplemental information to be provided by the Master Servicer to the Trustee.

          Notwithstanding the foregoing, the failure of the Master Servicer or
the Special Servicer to disclose any information otherwise required to be
disclosed pursuant to this Section 3.12, Section 3.27, Section 4.02(a) or
Section 4.02(b) shall not constitute a breach of this Section 3.12, Section
3.27, Section 4.02(a) or Section 4.02(b) to the extent that the Master Servicer
or the Special Servicer, as the case may be, so fails because such disclosure,
in the reasonable belief of the Master Servicer or the 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 Pooled
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. The Master Servicer or the 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).

          SECTION 3.13. Annual Statement as to Compliance.

          Each of the Master Servicer and the Special Servicer shall deliver to
the Trustee, the Depositor, each Underwriter, the holder of the Great Lakes
Crossing Companion Mortgage Loan, the Controlling Class Representative, the
Class GLC Directing Certificateholder, the Class RCKB Directing
Certificateholder and, to the extent required under the related A/B
Intercreditor Agreement, each B-Note Mortgage Loan Holder, 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 the Master Servicer or the Special Servicer, as the case may be,
during the preceding calendar year and of its performance under this Agreement
has been made under such officer's supervision, (ii) to the best of such
officer's knowledge, based on such review, the Master Servicer or the Special
Servicer, as the case may be, has fulfilled all of its obligations under this
Agreement in all material respects throughout such year (or, if there has been a
default in the fulfillment of any such obligation, specifying each such default
known to such officer and the nature and status thereof), and (iii) the Master
Servicer or the Special Servicer, as the case may be, has received no notice
regarding the qualification, or challenging the status, of any REMIC Pool as a
REMIC or any Grantor Trust Pool 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 of the Master Servicer and the Special
Servicer shall be required to deliver its Annual Performance Certification by
March 15 in 2004; and provided, further, that each of the Master Servicer and
the Special Servicer shall also be required to deliver its Annual Performance
Certification by March 15 in any given year subsequent to 2004 if it has
received written confirmation from the Trustee or the Depositor by January 31 of
that year subsequent to 2004 that an Annual 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 May 1 of each year, beginning in 2004, each of the Master
Servicer and the 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, each Underwriter, the holder of the
Great Lakes Crossing Companion Mortgage Loan, the Controlling Class
Representative, the Class GLC Directing Certificateholder, the Class RCKB
Directing Certificateholder and, to the extent required under the

                                     -169-

<PAGE>

related A/B Intercreditor Agreement, each B-Note Mortgage Loan Holder, to the
effect that such firm has examined the servicing operations of the Master
Servicer or the Special Servicer, as the case may be, for the previous calendar
year and that, on the basis of such examination, conducted substantially in
compliance with USAP, such firm confirms that the Master Servicer or the Special
Servicer, as the case may be, 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 each of the Master Servicer
and the Special Servicer shall be required to cause the delivery of its Annual
Accountants' Report by March 15 in 2004; and provided, further, that each of the
Master Servicer and the Special Servicer shall also be required to cause the
delivery of its Annual Accountants' Report by March 15 in any given year
subsequent to 2004 if it has received written confirmation from the Trustee or
the Depositor by January 31 of that year that an Annual 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.

          The Master Servicer and the Special Servicer shall each 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 of the Master Servicer and Special Servicer shall afford to
the Trustee, any Fiscal Agent, the Depositor, each Rating Agency, the
Controlling Class Representative, the holder of the Great Lakes Crossing
Companion Mortgage Loan and, to the extent required under the related A/B
Intercreditor Agreement, each B-Note Mortgage Loan Holder, and to the OTS, the
FDIC and any other banking or insurance regulatory authority that may exercise
authority over any Certificateholder, any Certificate Owner, the holder of the
Great Lakes Crossing Companion Mortgage Loan or any B-Note Mortgage Loan Holder,
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 the Master Servicer or the Special Servicer, as the case may be, designated
by it. The Master Servicer and the Special Servicer each 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 holder of the Great Lakes Crossing Companion Mortgage Loan
or a B-Note Mortgage Loan Holder, the Master Servicer and the Special Servicer
may require registration (to the extent access is provided via the 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 the Master Servicer or the Special Servicer, as
applicable,

                                     -170-

<PAGE>

deems necessary or appropriate, conditioning access on the execution and
delivery of an agreement governing the availability, use and disclosure of such
information.

          (b) Neither the Master Servicer nor the Special Servicer 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 Servicer and the Special Servicer shall, without charge, make a
knowledgeable Servicing Officer available, at the option of the Controlling
Class Representative either by telephone or at the office of such Servicing
Officer, to answer questions from the Controlling Class Representative regarding
the performance and servicing of the Mortgage Loans and/or REO Properties for
which the Master Servicer or the Special Servicer, as the case may be, is
responsible.

          SECTION 3.16. Title to REO Property; REO Account.

          (a) If title to any REO Property is acquired, the deed or certificate
of sale shall be issued to the Trustee or its nominee, on behalf of the
Certificateholders (or, if such REO Property relates to an A/B Mortgage Loan
Pair or the Great Lakes Crossing Total Mortgage Loan, on behalf of the
Certificateholders and the related B-Note Mortgage Loan Holder or on behalf of
the Certificateholders and the holder of the Great Lakes Crossing Companion
Mortgage Loan, as applicable) 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 Special Servicer at
the expense of the Trust for the purpose of taking title to one or more REO
Properties pursuant to this Agreement. Any such limited liability company formed
by the Special Servicer 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. The Special
Servicer, on behalf of the Trust (or, if the subject REO Property relates to an
A/B Mortgage Loan Pair or the Great Lakes Crossing Total Mortgage Loan, on
behalf of the Trust and the related B-Note Mortgage Loan Holder or on behalf of
the Trust and the holder of the Great Lakes Crossing Companion Mortgage Loan, as
applicable), shall sell any REO Property by the end of the third 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 the 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 following
the year in which such acquisition occurred will not result in an Adverse REMIC
Event with respect to any REMIC Pool or an Adverse Grantor Trust Event with
respect to any Grantor Trust Pool. Regardless of whether the 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 Special Servicer shall act in accordance with
the Servicing Standard to liquidate the subject REO Property on a timely basis
within a customary and normal time frame for the sale of comparable properties.
If the Special Servicer is granted such REO Extension or obtains such Opinion of
Counsel with respect to any REO Property, the Special Servicer shall (i)
promptly forward a copy of such REO Extension or Opinion of Counsel to the

                                     -171-

<PAGE>

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 the 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
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) The 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 (or, if such REO Property relates to an A/B Mortgage Loan
Pair or the Great Lakes Crossing Total Mortgage Loan, on behalf of the Trust and
the related B-Note Mortgage Loan Holder or on behalf of the Trust and the holder
of the Great Lakes Crossing Companion Mortgage Loan, as applicable), then the
Special Servicer shall establish and maintain one or more accounts
(collectively, the "REO Account"), to be held on behalf of the Trustee in trust
for the benefit of the Certificateholders, for the retention of revenues and
other proceeds derived from each REO Property. Each account that constitutes the
REO Account shall be an Eligible Account. The Special Servicer shall deposit, or
cause to be deposited, in the REO Account, within one Business Day following
receipt, all REO Revenues, Insurance Proceeds, Condemnation Proceeds and
Liquidation Proceeds received in respect of an 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 related Investment
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 the REO Account prior to any change thereof.

          (c) The Special Servicer shall withdraw from the REO Account funds
necessary for the proper operation, management, leasing, maintenance and
disposition of any REO Property, but only to the extent of amounts on deposit in
the REO Account relating to such REO Property. On the Business Day following the
end of each Collection Period, the Special Servicer shall withdraw from the REO
Account and deposit, or deliver to the Master Servicer for deposit, into the
Collection Account (or, if the subject REO Property relates to an A/B Mortgage
Loan Pair or the Great Lakes Crossing Total Mortgage Loan, into the related A/B
Mortgage Loan Pair Custodial Account or the GLCTML Custodial Account, as
applicable), the aggregate of all amounts received in respect of each REO
Property during such Collection Period, net of any withdrawals made out of such
amounts pursuant to the preceding sentence; provided that, in the case of each
REO Property, the 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 such 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).

          SECTION 3.17. Management of REO Property.

          (a) Prior to the acquisition of title to any Mortgaged Property
securing a defaulted Mortgage Loan, the Special Servicer shall review the
operation of such Mortgaged Property and determine the nature of the income that
would be derived from such property if it were acquired by the Trust. If the
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 or to the tax imposed on
     "prohibited transactions" under Section 860F of the Code (either such tax
     referred to herein as an "REO Tax"), then such Mortgaged Property may be
     Directly Operated by the Special Servicer as REO Property;

               (ii) Directly Operating such Mortgaged Property as an REO
     Property could result in income from such property that would be subject to
     an REO Tax, but that a lease of such property to another party to operate
     such property, or the performance of some services by an Independent
     Contractor with respect to such property, or another method of operating
     such property would not result in income subject to an REO Tax, then the
     Special Servicer may (provided that in the judgment of the 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, then the Special Servicer shall deliver to
     the Trustee, 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 the Special Servicer and shall advise the
     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 the 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, the 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 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 Servicer 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.

                                     -173-

<PAGE>

          (b) If title to any REO Property is acquired, the Special Servicer
shall manage, conserve, protect and operate such REO Property for the benefit of
the Certificateholders (or, if such REO Property relates to an A/B Mortgage Loan
Pair or the Great Lakes Crossing Total Mortgage Loan, for the benefit of the
Certificateholders and the related B-Note Mortgage Loan Holder or for the
benefit of the Certificateholders and the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable) solely for the purpose of its prompt
disposition and sale in a manner that does not cause such REO Property to fail
to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code or, except as contemplated by Section 3.17(a), result in the receipt by
any REMIC Pool 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 any
REMIC Pool or in an Adverse Grantor Trust Event with respect to any Grantor
Trust Pool. Except as contemplated by Section 3.17(a), the 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 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(s)) 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 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 the 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 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 Master Servicer shall, at the
direction of the Special Servicer, make a Servicing Advance of such amounts as
are necessary for such purposes unless the Master Servicer or the Special
Servicer determines, in its reasonable judgment, that such advances would, if
made, be Nonrecoverable Servicing Advances; provided, however, that the 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.

          (c) The Special Servicer may 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;

                                     -174-

<PAGE>

               (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 the Special Servicer upon receipt;

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

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

The Special Servicer shall be entitled to enter into any agreement with any
Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Special Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. 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 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 Pooled 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.

          (b) If any Pooled Mortgage Loan becomes a Specially Designated
Defaulted Pooled Mortgage Loan, then the Special Servicer shall so notify the
Trustee, the Controlling Class Representative, the Master Servicer, the Class
GLC Directing Certificateholder (if the subject Pooled Mortgage Loan is the
Great Lakes Crossing Pooled Mortgage Loan) and the Class RCKB Directing
Certificateholder (if the subject Pooled Mortgage Loan is the Ritz-Carlton Key
Biscayne Pooled Mortgage Loan), and the Trustee shall, in turn, notify the
Holder(s) of the Controlling Class, in writing. In addition, the 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 Master Servicer and the Controlling Class Representative,
the Fair Value of such Pooled Mortgage Loan. The Special Servicer's
determination of the Fair Value of any Specially Designated Defaulted Pooled
Mortgage Loan shall be made as soon as reasonably practicable, but in no event
later than 20 days after the Special Servicer receives the requisite Appraisal
or any other third-party reports that it deems necessary to make the

                                     -175-

<PAGE>

determination. If at any time the Special Servicer becomes aware of any
circumstances or conditions that have occurred or arisen with respect to any
Specially Designated Defaulted Pooled Mortgage Loan or the related Mortgaged
Property subsequent to, and that would, in the Special Servicer's reasonable
judgment, materially affect, the Special Servicer's most recent Fair Value
determination with respect to such Specially Designated Defaulted Pooled
Mortgage Loan, then the Special Servicer shall redetermine (in the same manner
as provided above, but taking into account such new circumstances or conditions
known to the Special Servicer), and report to the Trustee, the Controlling Class
Representative, the Master Servicer, the holder of the Great Lakes Crossing
Companion Mortgage Loan (if the subject Pooled Mortgage Loan is the Great Lakes
Crossing Pooled Mortgage Loan), the Class GLC Directing Certificateholder (if
the subject Pooled Mortgage Loan is the Great Lakes Crossing Pooled Mortgage
Loan) and the Class RCKB Directing Certificateholder (if the subject Pooled
Mortgage Loan is the Ritz-Carlton Key Biscayne Pooled Mortgage Loan), 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 Pooled Mortgage
Loan.

          In determining the Fair Value of any Specially Designated Defaulted
Pooled Mortgage Loan, the Special Servicer shall take into account, among other
factors, the period and amount of the delinquency on such Pooled 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 a purchaser's foreclosing
on the related Mortgaged Property or working out such Pooled Mortgage Loan. In
addition, the 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 Pooled Mortgage
Loan without such an Appraisal; provided that the Special Servicer shall take
account of any change in the circumstances regarding or the condition of the
related Mortgaged Property known to the 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 Special
Servicer shall consider available objective third-party information obtained
from generally available sources, as well as information obtained from vendors
providing real estate services to the Special Servicer, concerning the market
for distressed real estate loans and the real estate market for the subject
property type in the area where the related Mortgaged Property is located. The
Special Servicer may, 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 the Special
Servicer pursuant to this Section 3.18(b) shall constitute, and be reimbursable
as, Servicing Advances. The other parties to this Agreement shall cooperate with
all reasonable requests for information made by the Special Servicer in order to
allow the Special Servicer to perform its duties pursuant to this Section
3.18(b).

          (c) The Majority Controlling Class Certificateholder (exclusive of the
Depositor, Column, KeyBank, or any of their respective Affiliates and/or agents)
may, at its option, purchase from the Trust any Specially Designated Defaulted
Pooled Mortgage Loan (such option, the "Purchase Option"), at a cash price (the
"Option Price") equal to the Fair Value of such Pooled Mortgage Loan (as most
recently determined by the Special Servicer and reported to the Trustee and the
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 Special
Servicer is in the process of redetermining such Fair Value because of a change
in circumstances, equal to the Purchase Price; provided that:

                                     -176-

<PAGE>

               (i) the Purchase Option with respect to any Specially Designated
     Defaulted Pooled Mortgage Loan will remain in effect only for the period
     (the "Option Period") that commences on the date that such Pooled Mortgage
     Loan first becomes a Specially Designated Defaulted Pooled Mortgage Loan
     and ends on the earliest of (A) the date on which such Pooled Mortgage Loan
     becomes a Corrected Pooled Mortgage Loan or otherwise ceases to be a
     Specially Designated Defaulted Pooled Mortgage Loan, (B) the date on which
     a Liquidation Event occurs with respect to such Pooled Mortgage Loan, and
     (C) the related Mortgaged Property becomes an REO Property;

               (ii) the Purchase Option with respect to any Specially Designated
     Defaulted Pooled Mortgage Loan will be assignable by the Majority
     Controlling Class Certificateholder during the Option Period to a third
     party other than the Depositor, Column, KeyBank, or one of their respective
     Affiliates and/or agents (provided that the parties hereto are notified in
     writing of the assignment);

               (iii) if the Purchase Option with respect to any Specially
     Designated Defaulted Pooled Mortgage Loan is not exercised by the Majority
     Controlling Class Certificateholder or any assignee thereof within 30 days
     after the Fair Value of such Pooled Mortgage Loan has initially been
     established as provided in Section 3.18(b) above, then the Majority
     Controlling Class Certificateholder shall be deemed to have assigned such
     Purchase Option, for a 30-day period only, to the Special Servicer;

               (iv) during the 30-day period following the assignment to it of
     the Purchase Option with respect to any Specially Designated Defaulted
     Pooled Mortgage Loan, the Special Servicer shall be entitled to exercise
     such Purchase Option or to assign such Purchase Option to a third party
     other than the Depositor, Column, KeyBank, or one of their respective
     Affiliates and/or agents (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 Pooled Mortgage Loan is not exercised by the Special
     Servicer or its assignee within the 30-day period following the assignment
     of such Purchase Option to the Special Servicer as contemplated by clause
     (iii) above, then such Purchase Option will automatically revert to the
     Majority Controlling Class Certificateholder;

               (vi) prior to any exercise of the Purchase Option with respect to
     any Specially Designated Defaulted Pooled Mortgage Loan by the Special
     Servicer or any Affiliate or assignee thereof, subject to the following
     paragraph, the Master Servicer shall confirm and report to the Trustee and
     the Special Servicer (or, if the Master Servicer and the Special Servicer
     are the same Person or Affiliates, the Trustee, upon reasonable notice,
     shall confirm and report to the Special Servicer) whether it believes that
     the Special Servicer's determination of the Fair Value of such Pooled
     Mortgage Loan reasonably reflects an amount no less than that which would,
     in its judgment, be realized in connection with a sale of such Pooled
     Mortgage Loan if it were offered in a commercially reasonable manner and an
     open bid auction were conducted; provided that the Special Servicer may
     revise any such Fair Value determination that is rejected by the Master
     Servicer (or, if applicable, the Trustee); and

               (vii) any purchase option provided for with respect to a
     Specially Designated Defaulted Pooled Mortgage Loan pursuant to this
     Section 3.18(c) shall, (i) in the case of the

                                     -177-

<PAGE>

     Great Lakes Crossing Pooled Mortgage Loan, be subject to the right of the
     holder of the Great Lakes Crossing Companion Mortgage Loan to purchase the
     Great Lakes Crossing Pooled Mortgage Loan pursuant to the terms of the
     Great Lakes Crossing Intercreditor Agreement, (ii) in the case of the Great
     Lakes Crossing Pooled Mortgage Loan, be subject to the rights of the Class
     GLC Directing Certificateholder to purchase the Great Lakes Crossing Pooled
     Mortgage Loan, in accordance with the provisions of Section 3.27 and (iii)
     in the case of the Ritz-Carlton Key Biscayne Pooled Mortgage Loan, be
     subject to the rights of the Class RCKB Directing Certificateholder to
     purchase the Ritz-Carlton Key Biscayne Pooled Mortgage Loan, in accordance
     with the provisions of Section 3.27.

          Notwithstanding anything contained in clause (vi) of the preceding
paragraph to the contrary, if the Master Servicer or the Trustee is required to
confirm or reject the Special Servicer's Fair Value determination as
contemplated by such clause (vi), either such party may (at its option)
designate an Independent third party, with adequate experience in the trading of
defaulted mortgage loans, to confirm the Special Servicer's Fair Value
determination as contemplated by such clause (vi). In the event that the Master
Servicer or the Trustee designates such a third party to make such
determination, neither the Master Servicer nor the Trustee will assume any
responsibility for such third party's determination, and the Master Servicer and
the Trustee shall be entitled to conclusively rely upon such third party's
determination. The Master Servicer may pay itself (or the Trustee, as the case
may be) a fee of up to $2,500 in connection with any such confirmation of a
Special Servicer's Fair Value determination, plus (subject to the next sentence)
related costs and expenses out of the Collection Account. The reasonable costs
of all confirming third-party's fees and expenses and all appraisals, inspection
reports and broker opinions of value, incurred by the Master Servicer or the
Trustee pursuant to this paragraph or clause (vi) of the preceding paragraph
shall be advanced by the Master Servicer and shall constitute, and be
reimbursable as, Servicing Advances.

          Any party entitled to do so may exercise the Purchase Option with
respect to any Specially Designated Defaulted Pooled Mortgage Loan by providing
to the Trustee, the Master Servicer and the 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 Special Servicer or the
     Majority Controlling Class Certificateholder, evidence of its right to
     exercise such Purchase Option.

The actual purchase of such Specially Designated Defaulted Pooled Mortgage Loan
shall occur (by delivery of cash in the amount of the applicable Option Price to
the Special Servicer for deposit in the Collection Account) no later than 20
days after the later of (i) such exercise of the Purchase Option with respect to
such Pooled Mortgage Loan and (ii) if applicable, the confirmation of the
Special Servicer's Fair Value of such Pooled 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).

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

                                     -178-

<PAGE>

          If the Great Lakes Crossing Pooled Mortgage Loan becomes a Specially
Designated Defaulted Pooled Mortgage Loan, the Special Servicer shall deliver to
the holder of the Great Lakes Crossing Companion Mortgage Loan copies of all
written and/or electronic information used by the Special Servicer to establish
the Fair Value of the Great Lakes Crossing Pooled Mortgage Loan, together with,
at the expense of such holder, such other information as such holder may
reasonably request to perform a similar valuation of the Great Lakes Crossing
Companion Mortgage Loan.

          (d) The 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)). The 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 the
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 the
Special Servicer shall, consistent with the Servicing Standard and subject to
Section 3.24, 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 Special Servicer shall give the Trustee and the Controlling Class
Representative (and, in the case of the Great Lakes Crossing Total Mortgage
Loan, the Class GLC Directing Certificateholder and the holder of the Great
Lakes Crossing Companion Mortgage Loan, and, in the case of the Ritz-Carlton Key
Biscayne Pooled Mortgage Loan, the Class RCKB Directing Certificateholder) 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 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 Special Servicer, the cost of which shall be covered by, and be reimbursable
as, a Servicing Advance). The appraiser conducting any such new Appraisal shall
be a Qualified Appraiser that is (i) selected by the Special Servicer if neither
the Special Servicer nor any Affiliate thereof is bidding with respect to the
subject REO Property and (ii) selected by the Trustee if either the Special
Servicer or any Affiliate thereof is so bidding. Where any Interested Person is
among those bidding with respect to any REO Property, the Special Servicer shall
require that all bids be submitted to it (or, if the 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, the Special Servicer shall take
into account the results of any Appraisal or updated Appraisal that it or the
Master Servicer may have

                                     -179-

<PAGE>

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 be deemed a fair price. Notwithstanding the other provisions of this
Section 3.18, no cash bid from the 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 the Special Servicer or any Affiliate) have been received. In the event
the bid of the 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 the Special Servicer or any Affiliate
thereof is the highest of all cash bids received, then the bid of the 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 Special
Servicer for any REO Property shall be unconditional; and, if accepted, the
subject REO Property shall be transferred to the 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 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 Pooled 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 Special Servicer may charge prospective
bidders, and may retain, fees that approximate the 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 the Collection
Account, the GLCTML Custodial Account or an A/B Mortgage Loan Pair Custodial
Account. Any sale of a Specially Designated Defaulted Pooled 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 Special Servicer nor the Trustee shall have any liability
to any Certificateholder, the holder of the Great Lakes Crossing Companion
Mortgage Loan or any related B-Note Mortgage Loan Holder with respect to the
purchase price therefor accepted by the Special Servicer or the Trustee.

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

          (h) The purchase price for any Specially Designated Defaulted Pooled
Mortgage Loan or REO Property sold under this Section 3.18 shall be deposited
into (or, in the case of an REO Property, transferred from the REO Account to)
the Collection Account (or, in the case of an REO Property that relates to an
A/B Mortgage Loan Pair or the Great Lakes Crossing Total Mortgage Loan, the
related A/B Mortgage Loan Pair Custodial Account or the GLCTML Custodial
Account, as applicable), and the Trustee, upon receipt of written notice from
the Master Servicer to the effect that such deposit has been made (based upon
notification by the Special Servicer to the 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

                                     -180-

<PAGE>

of such Pooled Mortgage Loan or REO Property in the Person who purchased such
Pooled Mortgage Loan or REO Property.

          (i) The parties hereto acknowledge the purchase options of the holder
of the Great Lakes Crossing Companion Mortgage Loan with respect to the Great
Lakes Crossing Pooled Mortgage Loan provided for in Section 3.27(g) and Section
3.27(h). The purchase price paid by the holder of the Great Lakes Crossing
Companion Mortgage Loan for the Great Lakes Crossing Total Mortgage Loan in
accordance with either such purchase option shall be deposited into the
Collection Account, and the Trustee, upon receipt of written notice from the
Master Servicer to the effect that such deposit and transfer 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 the Great Lakes Crossing Pooled Mortgage Loan in the holder
of the Great Lakes Crossing Companion Mortgage Loan.

          (j) The parties hereto acknowledge the purchase option of each B-Note
Mortgage Loan Holder with respect to the related Pooled A-Note Mortgage Loan
provided for in the related A/B Intercreditor Agreement. The purchase price paid
by any B-Note Mortgage Loan Holder for the related Pooled A-Note Mortgage Loan
in accordance with such purchase option shall be deposited into the Collection
Account, and the Trustee, upon receipt of written notice from the 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 Pooled A-Note Mortgage Loan in the related B-Note Mortgage
Loan Holder.

          (k) If pursuant to any purchase option provided for in the related
Mezzanine Loan Intercreditor Agreement, a Mezzanine Loan Holder purchases any
Pooled Mortgage Loan, then the purchase price paid by such Mezzanine Loan Holder
for such Pooled Mortgage Loan in accordance with such purchase option shall be
deposited into the Collection Account, and the Trustee, upon receipt of written
notice from the 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 Pooled Mortgage Loan in such Mezzanine Loan Holder.

          SECTION 3.19. Additional Obligations of Master Servicer.

          (a) The 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 lesser of
(i) the aggregate amount of Prepayment Interest Shortfalls incurred in
connection with Principal Prepayments received during the most recently ended
Collection Period with respect to the Mortgage Pool, and (ii) the aggregate of
(A) that portion of the Master Servicer's aggregate Master Servicing Fees for
the related Collection Period that is, in the case of each and every Pooled
Mortgage Loan and Pooled REO Loan for which such Master Servicing Fees are being
paid in such Collection Period, calculated at 0.02% per annum, and (B) all
Prepayment Interest Excesses and, to the extent earned on Principal Prepayments,
Net Investment Earnings received by the Master Servicer during the most recently
ended Collection Period; provided, however, that if a Prepayment Interest
Shortfall occurs as a result of the 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

                                     -181-

<PAGE>

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, the rate
referred to in clause (ii)(A) above shall be 0.05% per annum (except as to the
Pooled Mortgage Loans secured by the Mortgaged Properties identified on the
Pooled Mortgage Loan Schedule as Fairmount Place II, Southside Village Shopping
Center, Gray Road Industrial, Michigan Equities U Portfolio, Parkleigh North
Apartments, Crescent at Carlyle, The Carl Zeiss Building and BAE Systems
Building, for which it shall in each case be 0.02% per annum); and provided,
further, that the rights of the Certificateholders to offset the aggregate
Prepayment Interest Shortfalls shall not be cumulative.

          (b) No more frequently than once per calendar month, the Special
Servicer may require the Master Servicer, and the Master Servicer shall be
obligated, out of the Master Servicer's own funds, to reimburse the Special
Servicer for any unreimbursed Servicing Advances (other than Nonrecoverable
Servicing Advances) made by the Special Servicer, together with interest thereon
at the Reimbursement Rate from the date made to, but not including, the date of
reimbursement. Such reimbursement and any accompanying payment of interest shall
be made within ten Business Days of the written request therefor by wire
transfer of immediately available funds to an account designated by the Special
Servicer. Upon the Master Servicer's reimbursement to the Special Servicer of
any Servicing Advance and payment to the Special Servicer of interest thereon,
all in accordance with this Section 3.19(b), the Master Servicer shall for all
purposes of this Agreement be deemed to have made such Servicing Advance at the
same time as the Special Servicer actually made such Servicing Advance, and
accordingly, the Master Servicer shall be entitled to reimbursement for such
Servicing Advance, together with interest thereon in accordance with Section
3.05(a) or 3.04(e), as applicable, and Section 3.11(g), at the same time, in the
same manner and to the same extent as the Master Servicer would otherwise have
been entitled if it had actually made such Servicing Advance at the time the
Special Servicer did.

          Notwithstanding anything to the contrary contained in any other
Section of this Agreement, if the Special Servicer is required under this
Agreement to make a Servicing Advance with respect to any Mortgage Loan or REO
Property, but does not desire to do so, then the Special Servicer may, in its
sole discretion, request that the Master Servicer make such Servicing Advance.
Any such request shall be made, in writing, in a timely manner that does not
adversely affect the interests of any Certificateholder (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 Master Servicer may reasonably request; provided,
however, that the Special Servicer shall not be entitled to make such a request
of the Master Servicer (other than for emergency advances) more frequently than
once per calendar month (although such request may relate to more than one
Servicing Advance). The Master Servicer shall have the obligation to make any
such Servicing Advance (other than a Nonrecoverable Servicing Advance) that it
is so requested by the Special Servicer to make, within five (5) Business Days
of the Master Servicer's receipt of such request. If the request is timely and
properly made, the Special Servicer shall be relieved of any obligations with
respect to a Servicing Advance that it so requests the Master Servicer to make
with respect to any Mortgage Loan or REO Property (regardless of whether or not
the Master Servicer shall make such Servicing Advance). The Master Servicer
shall be entitled to reimbursement for any Servicing Advance made by it at the
direction of the Special Servicer, together with interest thereon in accordance
with Section 3.05(a) or 3.04(e), as applicable, and Section 3.11(g), at

                                     -182-

<PAGE>

the same time, in the same manner and to the same extent as the Master Servicer
is entitled with respect to any other Servicing Advances made thereby.

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

          (c) Promptly following the occurrence of an Appraisal Trigger Event
with respect to any Pooled Mortgage Loan, the Special Servicer shall obtain (or,
if such Pooled Mortgage Loan has a Stated Principal Balance of $2,000,000 or
less, unless the Controlling Class Representative permits or requires otherwise,
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
judgment of the Special Servicer, would materially affect the value of the
property in the earlier Appraisal, and shall deliver a copy of such Appraisal to
the Trustee, the 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 as, a Servicing Advance. Promptly following the
receipt of, and based upon, such Appraisal, the Special Servicer shall determine
and report to the Trustee, the Master Servicer and the Controlling Class
Representative the then applicable Appraisal Reduction Amount, if any, with
respect to the subject Required Appraisal Loan.

          For so long as any Pooled Mortgage Loan or Pooled REO Loan remains a
Required Appraisal Loan, the Special Servicer shall, within 30 days of each
anniversary of such loan's having become a Required Appraisal Loan, obtain (or,
if such Required Appraisal Loan has a Stated Principal Balance of $2,000,000 or
less, unless the Controlling Class Representative permits or requires otherwise,
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
as, a Servicing Advance. Promptly following the receipt of, and based upon, such
update, the Special Servicer shall redetermine and report to the Trustee and the
Master Servicer 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 Special Servicer obtain a new Appraisal of the subject Mortgaged Property in
accordance with MAI standards, at the expense of the Controlling Class
Certificateholders, and upon receipt of such Appraisal the Special Servicer
shall redetermine the Appraisal Reduction Amount.

          (d) In connection with each prepayment of principal received
hereunder, the Master Servicer shall calculate any applicable Prepayment Premium
or Yield Maintenance Charge, as the case may be, payable under any Pooled
Mortgage Loan. Promptly following its determination thereof, the Master Servicer
shall disclose to the Trustee and, upon request, to any Certificateholder and,
in the case of a B-

                                     -183-

<PAGE>

Note Mortgage Loan or the Great Lakes Crossing Companion Mortgage Loan, to the
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable, 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.

          (e) With respect to each Pooled Mortgage Loan that provides for
defeasance, the Master Servicer shall, to the extent permitted by the terms of
the related Mortgage Loan Documents, require the related Borrower (i) to provide
replacement collateral consisting of U.S. government securities within the
meaning of Treasury regulation section 1.860G-2(a)(8)(i) in an amount sufficient
to make all scheduled payments under the Pooled Mortgage Loan (or defeased
portion thereof) when due (and assuming, in the case of a Pooled ARD Mortgage
Loan, to the extent consistent with the related Mortgage Loan Documents, that
such Pooled 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 Master Servicer, to designate a single purpose entity
(which may be a subsidiary of the Master Servicer established for the purpose of
assuming all defeased Pooled Mortgage Loans) to assume the subject Pooled
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 Pooled 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, in the case of Moody's, the
subject Pooled 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 or, in the case of
Fitch, the affected Pooled Mortgage Loan, individually or together with all
other Pooled Mortgage Loans, if any, that are in the same Cross-Collateralized
Group as such Pooled Mortgage Loan, has a Stated Principal Balance in excess of
5% of the then aggregate Stated Principal Balance of the Mortgage Pool or is one
of the ten largest Pooled Mortgage Loans based on Stated Principal Balance, and
if either the terms of the subject Pooled Mortgage Loan permit the Master
Servicer to impose the foregoing requirements or the Master Servicer satisfies
such requirements on its own, then confirmation that such defeasance will not
result in an Adverse Rating Event is not required from the subject Rating
Agency. In such case, the 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 Pooled Mortgage Loan. However, if the
subject Pooled 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
if the terms of the subject Pooled Mortgage Loan do not permit the Master
Servicer to impose such requirements and the Master Servicer does not satisfy
such requirements on its own (or, with respect to Fitch, the affected Pooling
Mortgage Loan, individually or together with all other Pooled Mortgage Loans, if
any, that are in the same Cross-Collateralized Group as such Pooled Mortgage
Loan, has a Stated Principal Balance in excess of 5% of the then aggregate
Stated Principal Balance of the Mortgage Pool or is one of the ten largest
Pooled Mortgage Loans based on Stated Principal Balance), then the Master
Servicer shall so notify the Rating Agencies and the Controlling Class
Representative and, so long as the imposition of such a requirement would not
violate applicable law or the related Mortgage Loan Documents, 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 Master
Servicer shall not execute a defeasance unless (i) the subject Pooled Mortgage
Loan requires the related Borrower to pay all Rating Agency fees associated with
defeasance (if Rating Agency confirmation of no-downgrade is a

                                     -184-

<PAGE>

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 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 Master Servicer or the Special
Servicer which may result in legal expenses to the Trust Fund), and (ii) the
related 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 related Mortgage Loan Documents are
fully enforceable in accordance with their terms (subject to bankruptcy,
insolvency and similar standard exceptions), and any applicable rating
confirmations.

          Subject to the last sentence of Section 3.01(e), the provisions of
this Section 3.19(e) shall apply to any defeasance of the Great Lakes Crossing
Companion Mortgage Loan to the same extent as they apply to the Great Lakes
Crossing Pooled Mortgage Loan.

          (f) The Master Servicer shall, as to each Pooled 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 Pooled 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
Master Servicer.

          (g) If a Pooled 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 Pooled Mortgage
Loan may be accelerated and/or accrue Default Charges unless and until the
Master Servicer notifies such Borrower of the failure or the elapse of a
specified number of days following the Master Servicer's delivery of such
notice, then the 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.

          SECTION 3.20. Modifications, Waivers, Amendments and Consents.

          (a) The Special Servicer (solely as to a Specially Serviced Mortgage
Loan) or the Master Servicer (solely as to a Performing Mortgage Loan) may
(consistent with the Servicing Standard) agree to any modification, waiver or
amendment of any term of, extend the maturity of, defer or forgive interest
(including Default Interest and Post-ARD Additional Interest) on and principal
of, defer or forgive late payment charges, Prepayment Premiums and Yield
Maintenance Charges on, permit the release, addition or substitution of
collateral securing, and/or permit the release, addition or substitution of the
Borrower on or any guarantor of, any Mortgage Loan, subject, however, to
Sections 3.08 and 3.24 hereof, to the terms of any applicable intercreditor or
similar agreement (including, in the case of an A/B Mortgage Loan Pair or the
Great Lakes Crossing Total Mortgage Loan, the related A/B Intercreditor
Agreement or the Great Lakes Crossing Intercreditor Agreement, as applicable)
and to each of the following limitations, conditions and restrictions:

               (i) other than as provided in Sections 2.03(b), 3.02, 3.07, 3.08,
     3.20(f) and 3.20(g), the Master Servicer shall not agree to 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 affect the amount or timing of any related payment of principal,
     interest or other amount payable under such Mortgage Loan or adversely
     affect the security for such Mortgage Loan, unless, solely in the case of a
     Performing Mortgage Loan, the Master

                                     -185-

<PAGE>

     Servicer has obtained the consent of the Special Servicer (it being
     understood and agreed that (A) the Master Servicer shall promptly provide
     the Special Servicer with notice of any Borrower request for such
     modification, waiver or amendment, the Master Servicer's recommendations
     and analysis, and with all information reasonably available to the Master
     Servicer that the Special Servicer may reasonably request in order to
     withhold or grant any such consent, (B) the 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
     ten Business Days of the Special Servicer's receipt from the Master
     Servicer of the Master Servicer's recommendations and analysis and all
     information reasonably requested thereby and reasonably available to the
     Master Servicer in order to make an informed decision (or, if the Special
     Servicer did not request any information, within ten Business Days from
     such notice), such consent shall be deemed to have been granted);

               (ii) other than as provided in Sections 3.02, 3.07 and 3.08, the
     Special Servicer shall not agree to (or, in the case of a Performing
     Mortgage Loan, consent to the Master Servicer's agreeing to) any
     modification, waiver or amendment of any term of, or take (or, in the case
     of a Performing Mortgage Loan, consent to the 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 the 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 the 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 the Certificateholders
     (as a collective whole) (or, in the case of an A/B Mortgage Loan Pair or
     the Great Lakes Crossing Total Mortgage Loan, to the Certificateholders and
     the related B-Note Mortgage Loan Holder (as a collective whole) or to the
     Certificateholders and the holder of the Great Lakes Crossing Companion
     Mortgage Loan (as a collective whole), as applicable) on a present value
     basis (the relevant discounting of anticipated collections that will be
     distributable to Certificateholders and/or any B-Note Mortgage Loan Holder
     or the holder of the Great Lakes Crossing Companion Mortgage Loan, as
     applicable) to be done at the related Net Mortgage Rate), than would
     liquidation;

               (iii) the Special Servicer shall not extend (or, in the case of a
     Performing Mortgage Loan, consent to the Master Servicer's extending) 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
     Special Servicer shall have first determined in its reasonable judgment,
     based upon a Phase I Environmental Assessment (and any additional
     environmental testing that the 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

                                     -186-

<PAGE>

     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 Master Servicer nor the 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 REMIC Pool or an Adverse Grantor Trust Event with respect to
     any Grantor Trust Pool;

               (v) subject to applicable law, the related Mortgage Loan
     Documents and the Servicing Standard, neither the Master Servicer nor the
     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) the Special Servicer shall not permit (or, in the case of a
     Performing Mortgage Loan, consent to the Master Servicer's permitting) any
     Borrower to add or substitute any real property collateral for its Mortgage
     Loan unless the Special Servicer shall have first (A) determined in its
     reasonable judgment, based upon a Phase I Environmental Assessment (and any
     additional environmental testing that the 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 real property collateral is in
     compliance with applicable environmental laws and regulations and that
     there are no circumstances or conditions present with respect to such new
     real property 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;

               (vii) the Special Servicer shall not release (or, in the case of
     a Performing Mortgage Loan, consent to the Master Servicer's releasing),
     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 except in connection with a
     pending or threatened condemnation, or except where a Mortgage Loan (or, in
     the case of a Cross-Collateralized Group, the Great Lakes Crossing Total
     Mortgage Loan or an A/B Mortgage Loan Pair, where such entire
     Cross-Collateralized Group, the Great Lakes Crossing Total Mortgage Loan or
     such entire A/B Mortgage Loan Pair) is satisfied, or except in the case of
     a release where (A) the Rating Agencies have been notified in writing, (B)
     either (1) the use of the real property collateral to be released will not,
     in the reasonable judgment of the Special Servicer, materially and
     adversely affect the net operating income being generated by or the 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 real property collateral to be released (or substitute real
     estate collateral with an appraised value at least equal to that of the
     collateral to be released, is delivered), (C) the remaining Mortgaged
     Property (together with any substitute real property collateral) is, in the
     Special Servicer's reasonable judgment, adequate

                                     -187-

<PAGE>

     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); and

               (viii) any modification, waiver or amendment of a monetary term
     of the Great Lakes Crossing Total Mortgage Loan shall be structured so as
     to affect the Great Lakes Crossing Pooled Mortgage Loan and the Great Lakes
     Crossing Companion Mortgage Loan proportionately based on the respective
     amounts due thereunder;

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
Pooled Mortgage Loan, on the related date of substitution); and provided,
further, that, notwithstanding clauses (i) through (vii) above, neither the
Master Servicer nor the 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 Master
Servicer nor the Special Servicer shall be required to obtain any confirmation
of the Certificate ratings from the Rating Agencies in order to grant or consent
to easements or right-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 Pooled Mortgage Loan.

          (b) The Special Servicer and Master Servicer shall not have any
liability to the Trust, the Certificateholders, the holder of the Great Lakes
Crossing Companion Mortgage Loan, any related B-Note Mortgage Loan Holder 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, if applicable, any
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage 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 the Special Servicer or the 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 Pooled Mortgage Loan,
notwithstanding that the terms of such Pooled Mortgage Loan so permit or that
such interest may actually be capitalized; provided, however, that this sentence
shall not limit the rights of the Master Servicer or the Special Servicer on
behalf of the Trust to enforce any obligations of the related Borrower under
such Pooled Mortgage Loan.

          (d) Each of the Master Servicer and the 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 Master Servicer's or the Special Servicer's, as the case may

                                     -188-

<PAGE>

be, discretion 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(s)) for the additional
services performed in connection with such request, together with any related
costs and expenses incurred by it. All such fees collected by the Master
Servicer and/or the Special Servicer with respect to any Pooled Mortgage Loan or
the Great Lakes Crossing Companion 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) shall be in writing. Each
of the Special Servicer and the Master Servicer shall notify the other such
party, each Rating Agency, the Trustee, the Controlling Class Representative,
the Class GLC Directing Certificateholder and the holder of the Great Lakes
Crossing Companion Mortgage Loan (in the case of the Great Lakes Crossing Total
Mortgage Loan), the Class RCKB Directing Certificateholder (in the case of the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan), and the related B-Note Mortgage
Loan Holder (in the case of a B-Note Mortgage Loan), 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 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 any modification, waiver,
amendment or other action, promptly (and in any event within ten (10) Business
Days) following the execution thereof. In addition, following the execution of
any modification, waiver or amendment agreed to by the Special Servicer, or by
the Master Servicer with any required consent of the Special Servicer, pursuant
to Section 3.20(a) above, the Special Servicer or the 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 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 Master Servicer shall be permitted, with the consent of the
Controlling Class Representative (which consent shall be deemed granted if not
denied within five (5) Business Days), 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 Master Servicer has determined, in its reasonable
judgment, that waiving such Post-ARD Additional Interest is in accordance with
the Servicing Standard. The 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 to the contrary, neither the Master Servicer nor the Special
Servicer shall be required to seek the consent of the Special Servicer or any
Certificateholder or obtain any confirmation of the Certificate ratings

                                     -189-

<PAGE>

from the Rating Agencies in order to approve the following modifications,
waivers or amendments of the Performing Mortgage Loans: (i) waivers of minor
covenant defaults (other than financial covenants), including late financial
statements; (ii) waiver of Default Charges, in accordance with Section 3.02;
(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; or (vi)
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, (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 REMIC Pool or an Adverse Grantor Trust Event
with respect to any Grantor Trust Pool, (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 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 Master Servicer shall not terminate or change or
consent to the termination or change of the franchise for any Mortgaged Property
that is operated as a hospitality property, in any event without the prior
written consent of the Special Servicer (it being understood and agreed that (A)
the Master Servicer shall promptly provide the Special Servicer with its
analysis, recommendations and all information that the Special Servicer may
reasonably request and which information is in the possession of the Master
Servicer, in order to withhold or grant any such consent, (B) the 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 ten Business Days of the Special Servicer's receipt from the
Master Servicer of such analysis, recommendation and all information reasonably
requested thereby in order to make an informed decision (or, if the Special
Servicer did not request any information, within ten Business Days from such
notice), such consent shall be deemed to have been granted).

          (i) In connection with granting an extension of the maturity date of
any Pooled Mortgage Loan in accordance with Section 3.20(a), the Special
Servicer, in the case of a Specially Serviced Pooled Mortgage Loan, and the
Master Servicer, in the case of a Performing Pooled 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 Special
Servicer, the Trustee and the Controlling Class Representative audited operating
statements on a quarterly basis with respect to the related Mortgaged Property;
provided that the Special Servicer or the 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 Master Servicer and the Special
Servicer are the same Person, the Master Servicer shall not be obligated to
obtain the consent or approval of the 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

                                     -190-

<PAGE>

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 Special Servicer is required to request such consent or approval of the
Controlling Class Representative pursuant to Section 3.24 or any other section
or provision of this Agreement.

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

          (a) Upon determining that a Servicing Transfer Event has occurred with
respect to any Mortgage Loan, the Master Servicer shall immediately give notice
thereof to the Controlling Class Representative (and, in the case of the Great
Lakes Crossing Total Mortgage Loan, to the Class GLC Directing Certificateholder
and the holder of the Great Lakes Crossing Companion Mortgage Loan and, in the
case of the Ritz-Carlton Key Biscayne Mortgage Loan, to the Class RCKB Directing
Certificateholder, as applicable), and if the Master Servicer is not also the
Special Servicer, the Master Servicer shall immediately give notice thereof, and
shall deliver the related Servicing File, to the Special Servicer and shall use
its best efforts to provide the Special Servicer with all information, documents
(or copies thereof) and records (including records stored electronically on
computer tapes, magnetic discs and the like) relating to such Mortgage Loan and
reasonably requested by the 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 Master Servicer or any
Sub-Servicer thereof, the information, documents and records to be delivered by
the Master Servicer to the Special Servicer pursuant to the prior sentence shall
include, but not be limited to, financial statements, appraisals,
environmental/engineering reports, leases, rent rolls, title insurance policies,
UCC's and tenant estoppels. The Master Servicer shall use its best efforts to
comply with the preceding two sentences within five (5) Business Days of the
occurrence of each related Servicing Transfer Event. No later than 30 days
before the Master Servicer is required to deliver a copy of the related
Servicing File to the 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.

          Upon determining that a Specially Serviced Pooled Mortgage Loan or, if
applicable, the Great Lakes Crossing Companion Mortgage Loan, has become a
Corrected Mortgage Loan and if the Master Servicer is not also the Special
Servicer, the Special Servicer shall immediately give notice thereof, and shall
return the related Servicing File within five (5) Business Days, to the Master
Servicer; and, upon giving such notice and returning such Servicing File to the
Master Servicer, the Special Servicer's obligation to service such Corrected
Mortgage Loan (and, in the case of a Pooled A-Note Mortgage Loan, any related
B-Note Mortgage Loan), and the Special Servicer's right to receive the Special
Servicing Fee with respect to such Corrected Mortgage Loan, shall terminate, and
the obligations of the Master Servicer to service and administer such Corrected
Mortgage Loan shall resume.

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

                                     -191-

<PAGE>

Corrected Pooled Mortgage Loan at anytime that a continuing Servicing Transfer
Event exists with respect to another Cross-Collateralized Pooled Mortgage Loan
in the same Cross-Collateralized Group.

          (b) In servicing any Specially Serviced Mortgage Loan, the 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 Master Servicer and, in the case of a
B-Note Mortgage Loan or the Great Lakes Crossing Total Mortgage Loan, the
related B-Note Mortgage Loan Holder or the holder of the Great Lakes Crossing
Companion Mortgage Loan, as applicable), 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) The Master Servicer and the Special Servicer shall each furnish to
the 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 of the Master Servicer
and the Special Servicer shall be entitled to rely upon written information
provided to it by the other.

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

          SECTION 3.22. Sub-Servicing Agreements.

          (a) The Master Servicer and, subject to Section 3.22(f), the 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 the Master Servicer or the
Special Servicer, as the case may be, shall for

                                     -192-

<PAGE>

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 Master
Servicer or 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 the Master Servicer or the 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 the Master
Servicer or the 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 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 Pooled Mortgage Loan pursuant
to this Agreement to terminate such agreement with respect to such purchased
Pooled 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 the Master Servicer or the Special Servicer, as the case may be,
contemplated by Section 3.08, Section 3.09 and/or Section 3.20 hereof without
the consent of the Master Servicer or the Special Servicer, as the case may be;
and (vi) does not permit the subject Sub-Servicer any rights of indemnification
out of the Trust Fund except through the Master Servicer or the Special
Servicer, as the case may be, pursuant to Section 6.03; provided that the
appointment by the Master Servicer or the 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 the Master Servicer or the
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 the Master Servicer shall purport to
delegate or effectively delegate to the related Sub-Servicer any of the rights
or obligations of the Special Servicer with respect to any Specially Serviced
Mortgage Loan or otherwise. Each Sub-Servicing Agreement entered into by the
Special Servicer shall relate only to Specially Serviced Mortgage Loans and REO
Properties and shall not purport to delegate or effectively delegate to the
related Sub-Servicer any of the rights or obligations of the Master Servicer
with respect to any Mortgage Loan, including any Specially Serviced Mortgage
Loan. The Master Servicer and the Special Servicer shall each notify the other,
the Trustee, the Depositor, any affected B-Note Mortgage Loan Holder and, if the
Great Lakes Crossing Total Mortgage Loan will be affected, the holder of the
Great Lakes Crossing Companion Mortgage Loan, in writing promptly of the
appointment by it of any Sub-Servicer. The Master Servicer and the Special
Servicer shall each 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 the Master Servicer or the
Special Servicer include actions taken or to be taken by a Sub-Servicer on
behalf of the Master Servicer or the Special Servicer, as the case may be; and,
in connection therewith, all amounts advanced by any Sub-Servicer to satisfy the
obligations of the Master Servicer or the Special Servicer hereunder to make
Advances shall be deemed to have been advanced by the Master Servicer or the
Special Servicer, as the case may be, out of its own funds and, accordingly,
such Advances shall be recoverable by such Sub-Servicer in the same manner and
out of the same funds as if such Sub-Servicer were the Master Servicer or the
Special Servicer, as the case may be. Such

                                     -193-

<PAGE>

Advances shall accrue interest in accordance with Sections 3.11(g) and/or
4.03(e), such interest to be allocable between the Master Servicer or the
Special Servicer, as the case may be, and such Sub-Servicer as they may agree.
For purposes of this Agreement, the Master Servicer and the Special Servicer
shall each 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.

          (c) The Master Servicer and the Special Servicer, for the benefit of
the Trustee and the Certificateholders, shall (at no expense to the other such
party or to the Trustee, the Certificateholders, the Trust, the holder of the
Great Lakes Crossing Companion Mortgage Loan or any B-Note Mortgage Loan Holder)
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 the Master Servicer or the 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 the Master Servicer or
the Special Servicer, as applicable, to terminate a Sub-Servicer, the Master
Servicer and the 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, the holder of the Great Lakes Crossing
Companion Mortgage Loan (if such Mortgage Loan is affected) and any affected
B-Note Mortgage Loan Holder.

          (d) If the Master Servicer or the 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 Master Servicer or Special
Servicer, as the case may be, shall succeed to the rights and assume the
obligations of the Master Servicer or the Special Servicer under any
Sub-Servicing Agreement, 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 Master Servicer or
Special Servicer, then the Master Servicer or the 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,
the Master Servicer and the Special Servicer shall each remain obligated and
liable to the Trustee, the Certificateholders, the holder of the Great Lakes
Crossing Companion Mortgage Loan and the B-Note Mortgage Loan Holders 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 it alone were servicing and administering the
Mortgage Loans or REO Properties for

                                     -194-

<PAGE>

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.

          (f) The 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; or (ii)
such agreement relates to one or more Pooled Mortgage Loans (including any such
Pooled 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 Pooled Mortgage Loans.

          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. Upon (i) the receipt by the Trustee of written
requests for the selection of a Controlling Class Representative from the
Holders (or, in the case of Book-Entry Certificates, the Certificate Owners) of
Certificates representing more than 50% of the Class Principal Balance of the
Controlling Class, (ii) the resignation or removal of the Person acting as
Controlling Class Representative or (iii) a determination by the Trustee that
the Controlling Class has changed, the Trustee shall promptly notify the
Depositor and the Holders (and, in the case of Book-Entry Certificates, to the
extent actually known to a Responsible Officer of the Trustee or identified
thereto by the Depositary or the Depositary 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 may
include the designation of the Controlling Class Representative by the Majority
Controlling Class Certificateholder by a writing delivered to the Trustee. No
appointment of any Person as a Controlling Class Representative shall be
effective until such Person provides the Trustee 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). Subject to
the preceding sentence, Allied Capital Corporation shall serve as the initial
Controlling Class Representative.

          (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 the
Master Servicer or the Special Servicer, the Trustee shall deliver to each of
the Master Servicer and the Special Servicer 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 Depositary or the Depositary 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

                                     -195-

<PAGE>

it by the Holders (or, in the case of Book-Entry Certificates, subject to
Section 5.06, by the Depositary or the Certificate Owners) of such Certificates,
and the Master Servicer and the Special Servicer shall each be entitled to rely
on such information provided by the Trustee with respect to any obligation or
right hereunder that the Master Servicer or the Special Servicer, 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 Servicer, the Master
Servicer and 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 Servicer, the Master Servicer and
such existing Controlling Class Representative.

          (d) 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.

          (e) Any and all expenses of the Controlling Class Representative shall
be borne by the Holders (or, if applicable, the Certificate Owners) of
Certificates of the Controlling Class, pro rata according to their respective
Percentage Interests in such Class, and not by the Trust. 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 Servicer and the Special Servicer, whereupon (if the Special Servicer,
the Master Servicer, the Trustee or the Trust are also named parties to the same
action and, in the sole judgment of the Special Servicer, (i) the Controlling
Class Representative had acted in good faith, without negligence or willful
misfeasance, with regard to the particular matter, and (ii) there is no
potential for the Special Servicer, the Master Servicer, the Trustee or the
Trust to be an adverse party in such action as regards the Controlling Class
Representative) the 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 Controlling Class Representative will be entitled to advise
the Special Servicer with respect to the Special Servicer's taking, or
consenting to the Master Servicer's taking, any of the actions identified in

anything in any other Section of this Agreement to the contrary, but in all
cases subject

                                     -196-

<PAGE>

to Section 3.20(g) and Section 3.24(b), the Special Servicer will not be
permitted to take, or consent to the Master Servicer's taking, any of the
actions identified in clauses (i) through (x) of this sentence, unless and until
the Special Servicer has notified the Controlling Class Representative in
writing of the Special Servicer's intent to take or permit the particular action
(which the Special Servicer shall promptly do, taking into account any time
period within which it must respond to the Master Servicer) and the Controlling
Class Representative has consented (or has failed to object) thereto in writing
within five (5) Business Days of having been notified thereof in writing and
having been provided with all reasonably requested information with respect
thereto (provided that such period to respond shall not extend beyond the
related approval period of the Special Servicer, if applicable):

               (i) any proposed or actual 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
     Pooled Mortgage Loan that 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 Pooled Mortgage Loan;

               (iii) any proposed sale of an REO Property (other than in
     connection with the termination of the Trust Fund) for less than the
     Purchase Price;

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

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

               (vi) any release of real property collateral for a Pooled
     Mortgage Loan (other than any release (a) required by the terms of, or upon
     satisfaction of, such Pooled Mortgage Loan, (b) made in connection with a
     pending or threatened condemnation action, or (c) made in connection with
     the grant of a non-material easement or right-of-way);

               (vii) any acceptance of substitute or additional collateral for a
     Specially Serviced Pooled Mortgage Loan (other than required by the terms
     of such Pooled Mortgage Loan);

               (viii) any releases of Earn-Out Reserve Funds or related Letters
     of Credit with respect to a Mortgaged Property (other than required by the

<PAGE>

     casualty or other insurance that provides coverage for acts of terrorism,
     despite the fact that such insurance may be required under the terms of the
     related Mortgage Loan;

provided that, in the event that the Special Servicer determines that immediate
action is necessary to protect the interests of the Certificateholders (as a
collective whole) (or, in the case of an A/B Mortgage Loan Pair or the Great
Lakes Crossing Total Mortgage Loan, to protect the interests of the
Certificateholders and either the related B-Note Mortgage Loan Holder or the
holder of the Great Lakes Crossing Companion Mortgage Loan, as applicable, (as a
collective whole)), the Special Servicer may take any such action without
waiting for the Controlling Class Representative's response.

          In addition, subject to Section 3.24(b), the Controlling Class
Representative may direct the Special Servicer to take, or to refrain from
taking, such actions with respect to the servicing and administration of any
Specially Serviced Pooled Mortgage Loans and/or REO Properties as the
Controlling Class Representative may deem advisable or as to which provision is
otherwise made herein. Upon reasonable request, the Special Servicer shall
provide the Controlling Class Representative with any information in the Special
Servicer's possession with respect to such matters, including, without
limitation, its reasons for determining to take a proposed action; provided that
such information shall also be provided, in a written format, to the Trustee,
who shall make it available for review pursuant to Section 8.12(b).

          The Master Servicer or the Special Servicer, as applicable, shall
notify the Controlling Class Representative of any release or substitution of
real property collateral for a Pooled Mortgage Loan even if such release or
substitution is in accordance with such Pooled Mortgage Loan.

          (b) Notwithstanding anything herein to the contrary: (i) the Special
Servicer shall not have any right or obligation to consult with or to seek
and/or obtain consent or approval from the Controlling Class Representative
prior to acting, and the provisions of this Agreement requiring such shall be of
no effect, if the Controlling Class changes, during the period prior to the
initial selection of a Controlling Class Representative for the new Controlling
Class and, if any Controlling Class Representative resigns or is removed, during
the period following such resignation or removal 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 the Special
Servicer shall ignore and act without regard to any such advice, direction or
objection that the Special Servicer has determined, in its reasonable judgment,
would) (A) require or cause the Special Servicer to violate applicable law, the
terms of any Mortgage Loan or any other Section of this Agreement, including the
Special Servicer's obligation to act in accordance with the Servicing Standard,
(B) result in an Adverse REMIC Event with respect to any REMIC Pool or an

the Trust, the Depositor, the Master Servicer, the Special Servicer, any Fiscal
Agent, the Trustee, the holder of the Great Lakes Crossing Companion Mortgage
Loan, any B-Note Mortgage Loan Holder or any of their respective Affiliates,
members, managers, officers, directors, employees or agents, to any material
claim, suit or liability, or (D) expand the scope of the Master Servicer's or
the Special Servicer's responsibilities under this Agreement.

          (c) Each Certificateholder acknowledges and agrees, by its acceptance
of its Certificates, that: (i) the Controlling Class Representative may have
special relationships and interests that conflict with those of Holders of one
or more Classes of Certificates; (ii) the Controlling Class Representative may
act solely in the interests of the Holders of the Controlling Class; (iii) the

                                     -198-

<PAGE>

Controlling Class Representative does not have any duties or liability to the
Holders of any Class of Certificates other than the Controlling Class; (iv) the
Controlling Class Representative may take actions that favor interests of the
Holders of the Controlling Class over the interests of the Holders of one or
more other Classes of Certificates; and (v) the Controlling Class Representative
shall have no liability whatsoever for having so acted, and no Certificateholder
may take any action whatsoever against the Controlling Class Representative or
any director, officer, employee, agent or principal thereof for having so acted.

          SECTION 3.25. Replacement of Special Servicer.

          (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 any existing Special Servicer hereunder (with or without cause)
and appoint a successor Special Servicer; provided that, if any such removal is
made without cause, then the costs of transferring the special servicing
responsibilities to a successor Special Servicer will be paid by the
Certificateholders of the Controlling Class. In addition, if the Special
Servicer is terminated pursuant to Section 7.01, then, also subject to Section
3.25(b), the Controlling Class Representative shall be entitled to appoint a
successor Special Servicer (other than the Trustee) for 45 days following such
termination.

          (b) No removal of the 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, executed by the Person designated to be the successor 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 the
existing Special Servicer and/or the appointment of the Person designated to
serve as Special Servicer 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,
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 the existing 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 removed Special Servicer such Certificateholders' joint and several
undertaking to pay any expenses incurred by the Trustee and such removed 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 the 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 Account (or, to the extent
appropriate, the A/B Mortgage Loan Pair Custodial Accounts) of all of its
accrued and unpaid Special Servicing Fees, as and to the extent provided in
Section 3.05(a) and Section 3.04(e), and reimbursement from the successor
Special Servicer of all outstanding Servicing Advances made by the terminated
Special Servicer and all

                                     -199-

<PAGE>

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
Work-out Fees, as and to the extent expressly permitted by Section 3.11(c), and
(iii) the 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 such terminated Special Servicer with
respect to any Mortgage Loan or REO Property.

          (d) For so long as the Controlling Class Representative has not
terminated KRECM as the Special Servicer and appointed a successor Special
Servicer, the holder of the Great Lakes Crossing Companion Mortgage Loan shall
have the same rights (and shall be subject to the same limitations and
conditions) to terminate and replace the GLCTML Special Servicer (in respect of
the Great Lakes Crossing Total Mortgage Loan only) as the Controlling Class
Representative would have to terminate and replace the General Special Servicer;
provided that, the holder of the Great Lakes Crossing Companion Mortgage Loan
may only replace the GLCTML Special Servicer with one of the following
servicers: Lennar Partners, GMAC Commercial Mortgage Corporation, KRECM, Midland
Loan Services, Inc., ARCap Servicing, Inc. or Clarion Partners LLC; provided
that, in respect of any of the aforementioned servicers, if after the date
hereof there occurs any transfer of equity in any such servicer that results in
a change of control of such servicer, then such servicer may not be appointed as
a replacement GLCTML Special Servicer unless the Controlling Class
Representative provides to the holder of the Great Lakes Crossing Companion
Mortgage Loan written consent to such servicer being appointed as a replacement
GLCTML Special Servicer. In connection therewith, all of the terms and
conditions of Section 3.25(a), Section 3.25(b) and Section 3.25(c) shall apply,
except that references therein to "Special Servicer" shall mean solely the
GLCTML Special Servicer, references therein to "Controlling Class
Representative" shall mean the holder of the Great Lakes Crossing Companion
Mortgage Loan and references therein to "Certificateholders of the Controlling
Class" shall mean the holder of the Great Lakes Crossing Companion Mortgage
Loan.

          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 Pooled Mortgage Loan or Pooled REO 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
     Servicer or the Special Servicer, in that order, any Advance Interest due
     and owing to such party on outstanding

                                     -200-

<PAGE>

     Advances made thereby with respect to such Pooled Mortgage Loan or Pooled
     REO Loan, as the case may be;

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

               third, to pay any other outstanding expense incurred with respect
     to such Pooled Mortgage Loan or Pooled REO Loan, as the case may be, that,
     if not paid from Default Charges collected on such Pooled Mortgage Loan or
     Pooled REO Loan, as the case may be, will likely become an Additional Trust
     Fund Expense;

               fourth, to reimburse the Trust for any other Additional Trust
     Fund Expenses incurred since the Closing Date with respect to such Pooled
     Mortgage Loan or Pooled REO Loan, as the case may be, and previously paid
     from a source other than Default Charges on such Pooled Mortgage Loan or
     Pooled REO Loan, as the case may be; and

               fifth, to pay any remaining portion of such Default Charges as
     Additional Master Servicing Compensation to the Master Servicer, if such
     Default Charges accrued with respect to a Performing Pooled Mortgage Loan,
     and otherwise to pay any remaining portion of such Default Charges as
     Additional Special Servicing Compensation to the Special Servicer.

          (b) Default Charges applied to reimburse the Trust pursuant to either
clause second or clause fourth 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 either clause second or clause fourth
of Section 3.26(a) shall be deemed to offset payments of Advance Interest or
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 Pooled Mortgage Loan or Pooled REO Loan (whereupon such Advance
Interest or 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. Servicing of the Great Lakes Crossing Total Mortgage
                        Loan and the Ritz-Carlton Key Biscayne Pooled Mortgage
                        Loan.

          (a) Prior to taking or permitting any of the following actions with
respect to the Great Lakes Crossing Pooled Mortgage Loan and/or the Great Lakes
Crossing Companion Mortgage Loan, the Special Servicer shall notify the Class
GLC Directing Certificateholder and the holder of the Great Lakes Crossing
Companion Mortgage Loan, and prior to taking or permitting any of the following
actions with respect to the Ritz-Carlton Key Biscayne Pooled Mortgage Loan, the
Special Servicer shall notify the Class RCKB Directing Certificateholder, in
either such case, of the Special Servicer's intent to take or permit the
particular action:

               (i) if the subject Mortgage Loan or each of the subject Mortgage
     Loans, as the case may be, becomes a Specially Serviced Mortgage Loan, any
     foreclosure upon or

                                     -201-

<PAGE>

     comparable conversion, which may include the acquisition of an REO
     Property, of the ownership of the related Mortgaged Property;

               (ii) if the subject Mortgage Loan or each of the subject Mortgage
     Loans, as the case may be, becomes a Specially Serviced Mortgage Loan, any
     modification of a monetary term other than an extension of the original
     maturity date for two years or less;

               (iii) if the subject Mortgage Loan or each of the subject
     Mortgage Loans, as the case may be, becomes a Specially Serviced Mortgage
     Loan, any acceptance of a discounted payoff;

               (iv) if the subject Mortgage Loan or each of the subject Mortgage
     Loans, as the case may be, becomes a Specially Serviced Mortgage Loan, any
     determination to bring the related Mortgaged Property into compliance with
     applicable environmental laws;

               (v) if the subject Mortgage Loan or each of the subject Mortgage
     Loans, as the case may be, becomes a Specially Serviced Mortgage Loan, any
     release of real property collateral securing the subject Mortgage Loan(s)
     (other than any release (i) required by the terms of the subject Mortgage
     Loan(s), (ii) made in connection with a pending or threatened condemnation
     action, or (iii) made in connection with the grant of a non-material
     easement or right-of-way);

               (vi) if the subject Mortgage Loan or each of the subject Mortgage
     Loans, as the case may be, becomes a Specially Serviced Mortgage Loan, any
     acceptance of substitute or additional real property collateral (other than
     in accordance with the terms of the subject Mortgage Loan(s));

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

               (viii) any acceptance of an assumption agreement releasing the
     related Borrower from liability; and

               (ix) any determination by the Special Servicer in accordance with
     Section 3.07(a) not to maintain or cause the Borrower to maintain for the
     related Mortgaged Property all-risk casualty or other insurance that
     provides coverage for acts of terrorism, despite the fact that such
     insurance may be required under the terms of the subject Mortgage Loan or
     each of the subject Mortgage Loans, as the case may be;

The Special Servicer shall provide all information which the Special Servicer
considers to be material in connection with evaluating any such action to the
Class GLC Directing Certificateholder and the holder of the Great Lakes Crossing
Companion Mortgage Loan, if the subject action relates to the Great Lakes
Crossing Total Mortgage Loan, or to the Class RCKB Directing Certificateholder,
if the subject action relates to the Ritz-Carlton Key Biscayne Pooled Mortgage
Loan. Upon receipt of such notice, the Class GLC Certificateholder, the holder
of the Great Lakes Crossing Companion Mortgage Loan or the Class RCKB
Certificateholder, as the case may be, may contact the Special Servicer
regarding the proposed action. The Special Servicer shall have no obligation to
follow any advice of, or take any direction from, the Class GLC Directing
Certificateholder, the holder of the Great Lakes Crossing Companion Mortgage
Loan or the Class RCKB Directing Certificateholder, as the case may be, with
respect to any

                                     -202-

<PAGE>

of the proposed actions or otherwise. Notwithstanding the foregoing, if a Great
Lakes Crossing Change of Control Event has occurred and is continuing, the
Special Servicer is under no obligation to notify and consult with the Class GLC
Directing Certificateholder, and if a Ritz-Carlton Key Biscayne Change of
Control Event has occurred and is continuing, the Special Servicer is under no
obligation to notify and consult with the Class RCKB Directing
Certificateholder; provided, however, that a Great Lakes Crossing Change of
Control Event will not affect the obligation of the Special Servicer to notify
and consult with the holder of the Great Lakes Crossing Companion Mortgage Loan.

          (b) Prior to entering into any modification of the Great Lakes
Crossing Pooled Mortgage Loan or the Ritz-Carlton Key Biscayne Pooled Mortgage
Loan that would materially affect the monetary terms of the Great Lakes Crossing
Total Mortgage Loan or the Ritz-Carlton Key Biscayne Pooled Mortgage Loan, as
the case may be, the Master Servicer or Special Servicer, as applicable, shall
provide the Class GLC Directing Certificateholder, in the case of a modification
of the Great Lakes Crossing Pooled Mortgage Loan, or the Class RCKB Directing
Certificateholder, in the case of a modification of the Ritz-Carlton Key

          (d) The Master Servicer or the Special Servicer, as applicable, based
on their respective responsibilities, shall deliver to the Class GLC Directing
Certificateholder notice of any monetary or material non-monetary default with
respect to the Great Lakes Crossing Total Mortgage 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 Class GLC
Directing Certificateholder shall have the right to cure defaults, which (in the
case of monetary defaults) shall include the obligation to reimburse any related
Advances and Advance Interest (each such cure, a "Cure Event") with respect to
the Great Lakes Crossing Total Mortgage Loan within five (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 material non-monetary default following the
date of such notice (such period, a "Cure Period" and, any payments made to
effect any such cure, "Cure Payments"); provided, however, that no single such
Cure Event shall continue for a period of more than 90 consecutive days (i.e.,
the related Borrower must itself have cured the subject default, including
through the reimbursement of any related Cure Payment, within 90 days after the
related Cure Event) or, in the case of monetary defaults, three consecutive
monthly payment dates under the related Mortgage Loan Documents nor continue for
120 days or, in the case of monetary defaults, four monthly payment dates under
the related Mortgage Loan Documents, in aggregate, in any 365-day period; and
provided, further, that the Class GLC Directing Certificateholder shall not have

Mortgage Loan after the Distribution Date that precedes by two years the Rated
Final Distribution Date. In the event that the Class GLC Directing
Certificateholder makes a Cure Payment to the Master Servicer in respect of the
Great Lakes Crossing Total Mortgage Loan, then the right of the Class GLC
Directing Certificateholder to reimbursement for such Cure Payment (including
the reimbursement of a previous Advance made by the Master Servicer, the Special
Servicer or the Trustee or any Advance Interest) shall be subordinate to the
payment of all other amounts due with respect to the Great Lakes Crossing Total
Mortgage Loan. Notwithstanding the foregoing, the making of a Cure Payment by
the Class GLC Directing Certificateholder with respect to the Great Lakes
Crossing Total Mortgage Loan shall not act as a waiver of any amounts due under
the related Mortgage Loan Documents by the related Borrower.

          The Master Servicer or the Special Servicer, as applicable, based on
their respective responsibilities, shall deliver to the Class RCKB Directing
Certificateholder notice of any monetary or material non-monetary default with
respect to the Ritz-Carlton Key Biscayne Pooled Mortgage 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 Class RCKB
Directing Certificateholder shall have the right to cure defaults, which (in the
case of monetary defaults) shall include the obligation to reimburse any related
Advances and Advance Interest (each such cure, a "Cure Event") with respect to
the Ritz-Carlton Key Biscayne Pooled Mortgage Loan within five (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

                                     -205-

default following the date of such notice (such period, a "Cure Period" and, any
payments made to effect any such cure, "Cure Payments"); provided, however, that
no single such Cure Event shall continue for a period of more than 90
consecutive days (i.e., the related Borrower must itself have cured the subject
default, including through the reimbursement of any related Cure Payment, within
90 days after the related Cure Event) or, in the case of monetary defaults,
three consecutive monthly payment dates under the related Mortgage Loan
Documents nor continue for 120 days or, in the case of monetary defaults, four
monthly payment dates under the related Mortgage Loan Documents, in aggregate,
in any 365-day period; and provided, further, that the Class RCKB Directing
Certificateholder shall not have any right to cure defaults with respect to the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan after the Distribution Date that
precedes by two years the Rated Final Distribution Date. In the event that the
Class RCKB Directing Certificateholder makes a Cure Payment to the Master
Servicer in respect of the Ritz-Carlton Key Biscayne Pooled Mortgage Loan, then
the right of the Class RCKB Directing Certificateholder to reimbursement for
such Cure Payment (including the reimbursement of a previous Advance made by the
Master Servicer or the Trustee or any Advance Interest) shall be subordinate to
the payment of all other amounts due with respect to the Ritz-Carlton Key
Biscayne Pooled Mortgage Loan. Notwithstanding the foregoing, the making of a
Cure Payment by the Class RCKB Directing Certificateholder with respect to the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan shall not act as a waiver of any
amounts due under the related Mortgage Loan Documents by the related Borrower.

          (e) Any decisions made by the Master Servicer or Special Servicer, as
applicable, with respect to the Great Lakes Crossing Total Mortgage Loan or the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan, as the case may be, pursuant to
and in accordance with the Servicing Standard and the other provisions of this
Agreement, shall automatically be deemed to be reasonably exercised for purposes
of this Section 3.27 and this Agreement.

          (f) By its acceptance of a Certificate, each Certificateholder
confirms its understanding that: the Class GLC Directing Certificateholder and
the Class RCKB Directing Certificateholder may each take actions that favor the
interests of the Holders of the Class GLC Certificates and the Class RCKB
Certificates, respectively, over the interests of the Holders of other Classes
of Certificates and that the Class GLC Directing Certificateholder and the Class
RCKB Directing Certificateholder may each have special relationships and
interests that conflict with those of Holders of such other Classes of
Certificates; and, absent willful misfeasance, bad faith, negligence or
negligent disregard of obligations or duties on the part of the Class GLC
Directing Certificateholder or the Class RCKB Directing Certificateholder, as
applicable, each Certificateholder agrees to take no action against the Class
GLC Directing Certificateholder and the Class RCKB Directing Certificateholder
as a result of such a special relationship or conflict.

          (g) Prior to entering into any modification of the Great Lakes
Crossing Total Mortgage Loan that would materially affect the monetary terms of
the Great Lakes Crossing Total Mortgage Loan, the Master Servicer or Special
Servicer, as applicable, shall provide the holder of the Great Lakes Crossing
Companion Mortgage Loan 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. The holder of the Great Lakes Crossing Companion Mortgage
Loan shall have the right to purchase the Great Lakes Crossing Pooled Mortgage
Loan at a price equal to the Purchase Price therefor by delivering notice to the
Master Servicer or Special Servicer, within five (5) Business Days of receipt of
the materials described in the preceding sentence, that it intends to exercise

such 5-Business Day period or upon receipt of notice by the Master Servicer or
the Special Servicer, as the case may be, that the Great Lakes Crossing Pooled

of such Purchase Price, the Master Servicer shall deposit the same in the

option granted under this paragraph shall be in addition to the purchase option
granted pursuant to Section 3.27(h) hereof

          (h) At any time that the Great Lakes Crossing Pooled Mortgage Loan is
a Specially Serviced Loan (provided that the Great Lakes Crossing Pooled
Mortgage Loan is then in default or default with respect thereto is reasonably
foreseeable) and after expiration of the applicable Cure Period without the
occurrence of a Cure Event on the part of the Class GLC Directing
Certificateholder, the holder of the Great Lakes Crossing Companion Mortgage
Loan shall have the right, by written notice to the Master Servicer and the
Special Servicer (a "GLCCML Purchase Notice") delivered at any time during the
45-day period commencing at the end of the applicable Cure Period, to purchase
the Great Lakes Crossing Pooled Mortgage Loan, in whole but not in part, at the
applicable Purchase Price. Upon the delivery of the GLCCML Purchase Notice to
the Master Servicer and the Special Servicer, the Special Servicer shall, on
behalf of the Trust Fund, sell (and the holder of the Great Lakes Crossing
Companion Mortgage Loan shall purchase) the Great Lakes Crossing Pooled Mortgage

Special Servicer. The Purchase Price shall be calculated by the Special
Servicer, three (3) Business Days prior to the GLCCML Purchase Date and shall,
absent manifest error, be binding upon the holder of the Great Lakes Crossing
Companion Mortgage Loan. Concurrently with the payment to the Trust of the
related Purchase Price, the Special Servicer shall direct the Trustee to execute
at the sole cost and expense of the holder of the Great Lakes Crossing Companion
Mortgage Loan in favor of the holder of the Great Lakes Crossing Companion
Mortgage Loan assignment documentation which will assign the Great Lakes

the 45-day period commencing at the end of the applicable Cure Period, (b) 10
Business Days after delivery of notification by the Special Servicer to the

          (i) The Master Servicer and the Special Servicer each shall provide to
the holder of the Great Lakes Crossing Companion Mortgage Loan, with respect to

Charge received on (i) the Great Lakes Crossing Pooled Mortgage Loan or any

5.18166137933% multiplied by the portion of the subject principal prepayment
included in the Net Total Principal Distribution Amount for the related
Distribution Date, and the denominator of which is 1/12 of the product of the
Net Mortgage Rate for the Great Lakes Crossing Pooled Mortgage Loan or the
related Pooled REO Loan, as the case may be, multiplied by the entire amount of
such subject principal prepayment.

          If any Yield Maintenance Charge is received with respect to the
Ritz-Carlton Key Biscayne Pooled Mortgage Loan or any successor Pooled REO Loan
with respect thereto during any Collection Period, then the Trustee shall
withdraw from the Distribution Account and distribute to the Holders of the
Class RCKB Certificates, on the related Distribution Date, that portion of such
Yield Maintenance Charge equal to the product of: (i) the amount of such Yield
Maintenance Charge; multiplied by (ii) a fraction (not greater than one or less
than zero), the numerator of which is the portion of the subject principal
prepayment included in the Class RCKB Principal Distribution Amount for the

                                     -211-

related Distribution Date, and the denominator of which is the entire amount of
such subject principal prepayment.

          For purposes of determining the portion of any Prepayment Premium that
is distributable to the Holders of any Class of Yield Maintenance Certificates
on any Distribution Date, the applicable "Additional Yield Amount" shall be an
amount equal to the product of: (i) 25% of the amount of such Prepayment Premium
that is so distributable; multiplied by (ii) a fraction (not greater than one or
less than zero), the numerator of which is equal to the Principal Distribution
Amount with respect to such Class of Yield Maintenance Certificates for such
Distribution Date, and the denominator of which is equal to the Net Total
Principal Distribution Amount for such Distribution Date.

          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 applicable "Additional Yield Amount"
shall be an amount equal to the product of: (i) the amount of such Yield
Maintenance Charge (exclusive, however, in the case of any Yield Maintenance
Charge received on (1) the Great Lakes Crossing Pooled Mortgage Loan or any
successor Pooled REO Loan with respect thereto or (2) the Ritz-Carlton Key
Biscayne Pooled Mortgage Loan or any successor Pooled REO Loan with respect
thereto, of any portion thereof payable on the Class GLC Certificates or the
Class RCKB Certificates, as applicable); multiplied by (ii) a fraction (not
greater than one or less than zero), the numerator of which is equal to the
excess, if any, of (A) the Pass-Through Rate applicable to such Class of Yield
Maintenance Certificates for the corresponding Interest Accrual Period, over (B)
the relevant Discount Rate, and the denominator of which is equal to the excess,
if any, of (X) the Mortgage Rate for the Pooled Mortgage Loan or Pooled REO Loan
in respect of which such Yield Maintenance Charge was received, over (Y) the
relevant Discount Rate; multiplied by (iii) a fraction (not greater than one or
less than zero), the numerator of which is equal to the Principal Distribution
Amount with respect to such Class of Yield Maintenance Certificates for such
Distribution Date, and the denominator of which is equal to the Net Total
Principal Distribution Amount for such Distribution Date.

          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 Master Servicer to the Trustee.

          Any distributions of additional interest, in the form of Prepayment
Premiums and Yield Maintenance Charges, made with respect to the Class A-X
Certificates on any Distribution Date pursuant to this Section 4.01(d) shall be
allocated among the respective Components of such Class of Certificates on a pro
rata basis in accordance with the relative amounts by which their respective
Component Notional Amounts declined as a result of deemed distributions of
principal on the REMIC II Regular Interests on such Distribution Date pursuant
to Section 4.01(k) (or, if there were no such declines, then on a pro rata basis
in accordance with the relative sizes of their respective Component Notional
Amounts).

          (e) On each Distribution Date, the Trustee shall withdraw from the
Distribution Account any amounts then on deposit in the Class V-1/2 Sub-Account
of the Distribution Account that represent Post-ARD Additional Interest
collected in respect of the Pooled ARD Mortgage Loans and/or any successor
Pooled REO Loans with respect thereto (other than the Great Lakes Crossing
Pooled Mortgage Loan or any successor Pooled REO Loan with respect thereto)
during the related Collection Period and shall distribute such amounts to the
Holders of the Class V-1 Certificates. On each Distribution Date, the Trustee
shall withdraw from the Distribution Account any amounts then on deposit in the
Class V-1/2 Sub-Account of the Distribution Account that represent Post-ARD
Additional Interest collected in respect of the Great Lakes Crossing Pooled
Mortgage Loan and/or any successor Pooled REO Loan with respect thereto during
the related Collection Period and shall distribute the Initial Great Lakes
Crossing Senior Percentage of such amounts to the Holders of the Class V-1
Certificates and the Initial Great Lakes Crossing Junior Percentage of such
amounts to the Holders of the Class V-2 Certificates.

          On each Distribution Date, the Trustee shall withdraw from the
Distribution Account any amounts then on deposit in the Class V-3/4 Sub-Account
of the Distribution Account that represent RCKB Extra Interest collected in
respect of the Ritz-Carlton Key Biscayne Pooled Mortgage Loan or any successor
Pooled REO Loan with respect thereto during the related Collection Period and
shall distribute the Initial Ritz-Carlton Key Biscayne Senior Percentage of such
amounts to the Holders of the Class V-3 Certificates and the Initial
Ritz-Carlton Key Biscayne Junior Percentage of such amounts to the Holders of
the Class V-4 Certificates.

          On each Distribution Date, the Trustee shall withdraw from the
Distribution Account any amounts then on deposit in the Class A-X/SPPML
Sub-Account of the Distribution Account that represent an Additional Sully Place
Yield Maintenance Amount collected during the related Collection Period in
connection with the repurchase of the Sully Place Pooled Mortgage Loan as a
result of an Early Defeasance with respect thereto and shall distribute such
amount to the Holders of the Class A-X Certificates.

          (f) All distributions made with respect to each Class of Certificates
on each Distribution Date shall be allocated pro rata among the Holders of such
Certificates based on their respective Percentage Interests. Except as otherwise
provided below, all such distributions made with respect to each Class of
Certificates on each Distribution Date shall be made to the Holders of such
Certificates of record at the close of business on the related Record Date and,
in the case of each such Holder, shall be made by wire transfer of immediately
available funds to the account thereof at a bank or other entity having
appropriate facilities therefor, if such Holder shall have provided the Trustee
with 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 shall be made by check mailed to the address
of such Holder as it appears in the Certificate Register. The final distribution
on each Certificate (determined, in the case of a Principal Balance Certificate,
without regard to any possible future reimbursement of any portion of a
previously incurred Unfunded Principal Balance Reduction allocable to such
Certificate) will be made in like manner, but only upon presentation and
surrender of such Certificate at the offices of the Certificate Registrar or
such other location specified in the notice to Certificateholders of such final
distribution. Any distribution that is to be made with respect to a Principal
Balance Certificate in reimbursement of any portion of an Unfunded Principal
Balance Reduction allocable to such Certificate, which reimbursement is to occur
after the date on which such Certificate is surrendered as contemplated by the
preceding sentence, will be made by check

                                     -213-

<PAGE>

mailed to the Holder that surrendered such Certificate at the last address set
forth for such Holder in the Certificate Register or at any other address of
which the Trustee was subsequently notified in writing.

          (g) Each distribution with respect to a Book-Entry Certificate shall
be paid to the Depositary, as Holder thereof, and the Depositary shall be
responsible for crediting the amount of such distribution to the accounts of its
Depositary Participants in accordance with its normal procedures. Each
Depositary Participant shall be responsible for disbursing such distribution to
the related Certificate Owners that it represents and to each indirect
participating brokerage firm for which it acts as agent. Each such indirect
participating brokerage firm shall be responsible for disbursing funds to the
related Certificate Owners that it represents. None of the parties hereto shall
have any responsibility therefor except as otherwise provided by this Agreement
or applicable law. The Trustee and the Depositor shall perform their respective
obligations under the Letters of Representations Among the Depositor, the
Trustee and the initial Depositary, relating to the Class A-SP, Class A-X, Class
A-1, Class A-2, Class A-3, Class A-4, 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, Class
P, Class GLC and Class RCKB Certificates, copies of which Letters of
Representations are attached hereto as Exhibit P.

          (h) 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.

          (i) Except as otherwise provided in Section 9.01, whenever the Trustee
expects that the final distribution with respect to any Class of Certificates
will be made on the next Distribution Date (such final distribution to be
determined, in the case of a Class of Principal Balance Certificates, without
regard to any possible future reimbursement of any portion of a previously
incurred Unfunded Principal Balance Reduction in respect of such Class), the
Trustee shall, as promptly as possible (and, in any event, no later than three
Business Days) after the related Determination Date, mail to each Holder of such
Class of Certificates of record on such date a notice to the effect that:

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

               (ii) no interest shall accrue on such Certificates from and after
     the end of the Interest Accrual Period for such Distribution Date.

          Any funds not distributed to any Holder or Holders of Certificates of
such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and
credited to, and shall be held uninvested in trust in, the account or accounts
of the appropriate non-tendering Holder or Holders. If any Certificates as to
which notice has been given pursuant to this Section 4.01(i) 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
Certificateholders to surrender their Certificates for cancellation in order to
receive the final distribution with respect thereto. If within one year after
the second notice all such Certificates shall not have been

                                     -214-

<PAGE>

surrendered for cancellation, then the Trustee, directly or through an agent,
shall take such steps to contact the remaining non-tendering Certificateholders
concerning the surrender of their Certificates as it shall deem appropriate. The
costs and expenses of holding such funds in trust and of contacting such
Certificateholders following the first anniversary of the delivery of such
second notice to the non-tendering Certificateholders shall be paid out of such
funds. No interest shall accrue or be payable to any former Holder on any amount
held in trust pursuant to this paragraph. If any Certificates as to which notice
has been given pursuant to this Section 4.01(i), shall not have been surrendered
for cancellation by the second anniversary of the delivery of the second notice,
then, subject to applicable escheat laws, the Trustee shall distribute to the
Class R Certificateholders all unclaimed funds.

          (j) Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal withholding requirements respecting payments to
Certificateholders of interest or original issue discount that the Trustee
reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. If the Trustee
does withhold any amount from payments or advances of interest or original issue
discount to any Certificateholder pursuant to federal withholding requirements,
the Trustee shall indicate the amount withheld to such Certificateholder.

          (k) All distributions of current accrued interest made with respect to
each Class of Interest Only Certificates on each Distribution Date pursuant to
clause first of the first paragraph of Section 4.01(a), and allocable to any
particular Component of such Class of Certificates, shall be deemed to have
first been distributed from REMIC II to REMIC III on such Distribution Date as
current accrued interest with respect to such Component's Corresponding REMIC II
Regular Interest as part of such REMIC II Regular Interest's Interest
Distribution Amount for such Distribution Date. In addition, all distributions
of additional interest (in the form of Prepayment Premiums and Yield Maintenance
Charges) made with respect to the Class A-X Certificates on each Distribution
Date pursuant to Section 4.01(d), and allocable to any particular Component of
such Class of Certificates shall be deemed to have first been distributed from
REMIC II to REMIC III on such Distribution Date as additional interest (in the
form of Prepayment Premiums and Yield Maintenance Charges) with respect to such
Component's Corresponding REMIC II Regular Interest.

          All distributions made with respect to each Class of Principal Balance
Certificates on each Distribution Date pursuant to Section 4.01(a), Section
4.01(b) or Section 4.01(d) shall be deemed to have first been distributed from
REMIC II to REMIC III on such Distribution Date with respect to the
Corresponding REMIC II Regular Interest(s) for such Class of Certificates. In
each case, if such distribution on any such Class of Principal Balance
Certificates was a distribution of accrued interest (as part of the related
Interest Distribution Amount for the subject Distribution Date), of principal,
of additional interest (in the form of Prepayment Premiums and Yield Maintenance
Charges) or in reimbursement of any related Unfunded Principal Balance
Reductions with respect to such Class of Certificates, then the corresponding
distribution deemed to be made on the Corresponding REMIC II Regular Interest(s)
for such Class of Certificates pursuant to the preceding sentence shall be
deemed also to be a distribution of accrued interest (as part of the Interest
Distribution Amount(s) for such REMIC II Regular Interest(s) for the subject
Distribution Date), of principal, of additional interest (in the form of
Prepayment Premiums and Yield Maintenance Charges) or in reimbursement of any
related Unfunded Principal Balance Reductions with respect to such REMIC II
Regular Interest(s).

          The actual distributions made by the Trustee on each Distribution Date

Section 4.01(c) (to the extent such distributions relate to the REMIC III
Residual Interest) or Section 4.01(d), as applicable, shall be deemed to have

Trustee shall be deemed to have made out of the Standard Available Distribution

          first, distributions of interest with respect to the related Loan
     REMIC Regular Interest, up to its Interest Distribution Amount for such
     Distribution Date;

          second, distributions of principal with respect to the related Loan
     REMIC Regular Interest, up to the lesser of (i) the Uncertificated
     Principal Balance of the Loan REMIC Regular Interest immediately prior to

     Distribution Amount for such Distribution Date allocable to that Exhibit
     B-5 Mortgage Loan, any Replacement Pooled Mortgage Loan substituted for
     that Exhibit B-5 Mortgage Loan or any successor Pooled REO Loan with
     respect to the foregoing; and

          third, reimbursements of Unfunded Principal Balance Reductions with
     respect to the related Loan REMIC Regular Interest, up to its Loss

          The distributions deemed made by the Trustee on each Distribution Date
with respect to the REMIC II Regular Interests pursuant to Section 4.01(k) and
the REMIC I Regular Interests pursuant to Section 4.01(l), as well as the
distributions actually made by the Trustee on each Distribution Date with
respect to the Certificates pursuant to Section 4.01(a), Section 4.01(b),
Section 4.01(c) (to the extent such distributions relate to the REMIC I Residual
Interest, the REMIC II Residual Interest or the REMIC III Residual Interest) or
Section 4.01(d) shall be deemed to have been so made, in part, from the

forth in, Exhibit E-1 hereto (the "Trustee Report"), detailing the distributions
on such Distribution Date and the performance, both in the aggregate and

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

Trustee Report shall be deemed to have agreed to keep confidential the
information therein until such Trustee Report is filed with the Commission, and
the Trustee Report (or, if presented via the Trustee's internet website, such
internet website) shall bear a legend to such effect.

          On each Distribution Date, the Trustee shall provide or make available
electronically (or, upon request, by first class mail) to each Privileged
Person, at the same time that the Trustee Report is delivered or otherwise made
available thereto, each file and report comprising the CMSA Investor Reporting

such effect.

          The Trustee shall have no obligation to provide the information or

information or reports from the Master Servicer provided for herein, and the
Trustee shall not be in default hereunder due to a delay in providing the

failure to timely deliver any information or reports hereunder. None of the
Master Servicer, the Special Servicer 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 the
Master Servicer, the Special Servicer or the Trustee, as applicable. None of the

Trustee from time to time in the Trustee Report and in one or more written
notices delivered to the other parties hereto, the Controlling Class

Act, access to information regarding the Trust on the Trustee's internet website
will be conditioned to the party attempting to gain such access electronically
agreeing to keep confidential any such information that has not been filed with
the Commission.

          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).

          (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

                                     -223-

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 Pooled 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.
The Master Servicer and the Special Servicer shall promptly provide to the
Depositor and the Trustee such information regarding the Mortgage Loans and the
Mortgaged Properties as such party may reasonably request and that has been
furnished to, or may otherwise be in the possession of, the Master Servicer or
the 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, the Master Servicer shall, subject Section 4.03(c), either (i) remit from
its own funds to the Trustee for deposit into the Distribution Account an amount
equal to the aggregate amount of P&I Advances, if any, to be made by the Master
Servicer in respect of the Mortgage Pool for the related Distribution Date, (ii)
apply amounts held in the Collection Account for future distribution to
Certificateholders in subsequent months in discharge of any such obligation to
make such P&I Advances, or (iii) make P&I Advances in the form of any
combination of (i) and (ii) aggregating the total amount of such P&I Advances to
be made by the Master Servicer. Any amounts held in the Collection Account for
future distribution and so used to make P&I Advances in respect of the Mortgage
Pool shall be appropriately reflected in the Master Servicer's records and
replaced by the Master Servicer by deposit in the 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, the Master Servicer
shall not have made any P&I Advance in respect of the Mortgage Pool 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 the Master Servicer on such date,
then the Trustee shall provide notice of such failure to the 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 in respect of the Mortgage
Pool by 6:00 p.m., New York City time, on such P&I Advance Date, then the
Trustee shall (not later than 11:00 a.m., New York City time, on the related
Distribution Date) make, and if the Trustee fails to do so, any Fiscal Agent
shall (not later than 12:00 noon, New York City time, on the related
Distribution Date) make, the portion of such P&I Advances in respect of the
Mortgage Pool that was required to be, but was not, made or remitted, as the
case may be, by the Master Servicer with respect to the related Distribution
Date.

          On or before 2:00 p.m., New York City time, on each P&I Advance Date,
the Master Servicer shall, subject to Section 4.03(c) and Section 4.03(d), remit
from its own funds to the holder of

                                     -224-

<PAGE>

the Great Lakes Crossing Companion Mortgage Loan an amount equal to any P&I
Advance to be made in respect of the Great Lakes Crossing Companion Mortgage
Loan or any Companion REO Loan with respect thereto for such P&I Advance Date.

          (b) The aggregate amount of P&I Advances to be made by the Master
Servicer in respect of any Distribution Date (or, in the case of the Great Lakes
Crossing Companion Mortgage Loan or any successor Companion REO Loan with
respect thereto, in respect of any P&I Advance Date), subject to Section 4.03(c)
and Section 4.03(d) 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 and Work-out Fees, due or deemed due, as
the case may be, in respect of the Pooled Mortgage Loans (including Pooled
Balloon Mortgage Loans delinquent as to their respective Balloon Payments), the
Great Lakes Crossing Companion Mortgage Loan and any successor REO Loans with
respect to the foregoing 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 the Master
Servicer, the Special Servicer, the Trustee or any Fiscal Agent, as applicable,
that it has made (or, in the case of a determination made by the Special
Servicer, that the Master Servicer has made) a Nonrecoverable P&I Advance or
that any proposed P&I Advance, if made, would constitute a Nonrecoverable P&I
Advance, shall be evidenced by an Officer's Certificate delivered (i) to the
Trustee and the Depositor, in the case of the Master Servicer, (ii) to the
Master Servicer and the Trustee, in the case of the Special Servicer, (iii) to
the Depositor and the Master Servicer, in the case of the Trustee or any Fiscal
Agent, and (iv) in each case, to the Controlling Class Representative, the Class
RCKB Directing Certificateholder (if the Ritz-Carlton Key Biscayne Pooled
Mortgage Loan or any related Pooled REO Loan is involved), and the Class GLC
Directing Certificateholder and the holder of the Great Lakes Crossing Companion
Mortgage Loan (if the Great Lakes Crossing Total Mortgage Loan or any related
Pooled REO Loan is involved), and setting forth such determination of
nonrecoverability and the considerations of the Master Servicer, the Special
Servicer or the Trustee, as applicable, forming the basis of such determination
(which shall include but shall not be limited to information, to the extent
available, such as related income and expense statements, rent rolls, occupancy
status, property inspections, and shall include an Appraisal (provided that if
an Appraisal has been obtained within the past 12 months, no new Appraisal is
required) of the related Mortgaged Property, the cost of which Appraisal shall
be advanced by the Master Servicer as a Servicing Advance). Such Officer's
Certificate shall be accompanied by the Appraisal and all other supporting
documentation relevant to the subject parties' nonrecoverability determination.
The Trustee

                                     -225-

<PAGE>

and any Fiscal Agent shall be entitled to conclusively rely on the Master
Servicer's determination that a P&I Advance is nonrecoverable. The Master
Servicer, the Trustee and any Fiscal Agent shall be entitled to conclusively
rely on the Special Servicer's determination that a P&I Advance is
nonrecoverable.

          (d) Notwithstanding anything herein to the contrary, no P&I Advance in
respect of the Great Lakes Crossing Companion Mortgage Loan shall be required to
be made hereunder (i) at any time, by the Trustee or any Fiscal Agent, or (ii)
prior to the securitization of the Great Lakes Crossing Companion Mortgage Loan
as contemplated by the Great Lakes Crossing Intercreditor Agreement (the "Great
Lakes Crossing Companion Mortgage Loan Securitization"), by the Master Servicer;
provided, however, that prior to the Great Lakes Crossing Companion Mortgage
Loan Securitization, the Master Servicer may make P&I Advances in respect of the
Great Lakes Crossing Companion Mortgage Loan upon request of the holder of the
Great Lakes Crossing Companion Mortgage Loan, in which case any P&I Advances not
ultimately recoverable from amounts received in respect of the Great Lakes
Crossing Companion Mortgage Loan will be reimbursed to the Master Servicer by
the holder of the Great Lakes Crossing Companion Mortgage Loan.

          (e) The 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 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, subject to the last
three sentences of this Section 4.03(e), out of general collections on the
Pooled Mortgage Loans and REO Properties on deposit in the Collection Account.
The Master Servicer shall reimburse itself, the Trustee or any Fiscal Agent, as
applicable, for any outstanding P&I Advance made thereby as soon as practicable
after funds available for such purpose are deposited in the Collection Account
or, in the case of a P&I Advance made with respect to a Pooled A-Note Mortgage
Loan or any successor Pooled REO Loan with respect thereto, in an A/B Mortgage
Loan Pair Custodial Account or, in the case of a P&I Advance made with respect
to the Great Lakes Crossing Pooled Mortgage Loan, the Great Lakes Crossing
Companion Mortgage Loan or any successor REO Loan with respect to either of the
foregoing Mortgage Loans, in the GLCTML Custodial Account, and in no event shall
interest accrue in accordance with this Section 4.03(e) 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. The Master Servicer shall not be
entitled to Advance Interest on any particular P&I Advance made thereby to the
extent a payment that covers such P&I Advance is received but is being held by
or on behalf of the Master Servicer in suspense. In addition, notwithstanding
the foregoing provisions of this Section 4.03(e), Advance Interest earned on any
Advances made with respect to either Mortgage Loan of an A/B Mortgage Loan Pair
or with respect to any REO Property related to an A/B Mortgage Loan Pair shall
be payable out of the related A/B Mortgage Loan Pair Custodial Account, to the
maximum extent permitted by the related A/B Intercreditor Agreement, before
being paid out of general collections on the Mortgage Pool on deposit in the
Collection Account. Further, notwithstanding the foregoing provisions of this
Section 4.03(e), Advance Interest earned on any Advances made with respect to
the Great Lakes Crossing Pooled Mortgage Loan or the Great Lakes Crossing
Companion Mortgage Loan or with respect to any REO Property related to the Great
Lakes Crossing Total Mortgage

                                     -226-

<PAGE>

Loan shall be payable out of the related GLCTML Custodial Account, to the
maximum extent permitted by the related Great Lakes Crossing Intercreditor
Agreement, before Advance Interest earned on any Advances made with respect to
the Great Lakes Crossing Pooled Mortgage Loan is paid out of general collections
on the Mortgage Pool on deposit in the Collection Account; provided, however,
that no amount of Advance Interest earned on any Advances made with respect to
the Great Lakes Crossing Companion Mortgage Loan or any successor Companion REO
Loan with respect thereto shall be paid out of general collections on the
Mortgage Pool on deposit in the Collection Account, as such Advance Interest
shall only be paid, if at all, out of amounts received in the GLCTML Custodial
Account in respect of the Great Lakes Crossing Companion Mortgage Loan.
Notwithstanding any other provisions herein to the contrary, the Master
Servicer, the Trustee and any Fiscal Agent shall only be entitled to
reimbursement for any outstanding P&I Advance (and interest thereon) made in
respect of the Great Lakes Crossing Companion Mortgage Loan or any successor
Companion REO Loan with respect thereto out of amounts received on that Mortgage
Loan and no amounts out of the Collection Account shall be used for such
reimbursement.

          SECTION 4.04. Allocation of Realized Losses and Additional Trust Fund
                        Expenses.

          (a) On each Distribution Date, following the distributions to
Certificateholders to be made on such date pursuant to Section 4.01, the Trustee
shall determine the amount, if any, by which (i) the then aggregate of the Class
Principal Balances of all the Classes of Principal Balance Certificates
(exclusive of the Class GLC and Class RCKB Certificates), exceeds (ii) the
aggregate Stated Principal Balance of the Mortgage Pool (net of the aggregate
Uncertificated Principal Balance of REMIC I Regular Interest GLC-2 and REMIC I
Regular Interest RCKB-2) that will be outstanding immediately following such
Distribution Date. If such excess does exist, then the Class Principal Balances
of the Class P, Class O, Class N, Class M, Class L, Class K, Class J, Class H,
Class G, Class F, Class E, Class D, Class C and Class B Certificates shall be
reduced sequentially, in that order, until such excess is reduced to zero;
provided that, no such Class of Certificates shall have its Class Principal
Balance reduced unless and until the Class Principal Balance of each other Class
of Certificates, if any, listed in front of it has been reduced to zero; and
provided, further, that if after the foregoing reductions, the amount described
in clause (i) of the preceding sentence still exceeds the amount described in
clause (ii) of such sentence, then the respective Class Principal Balances of
the Class A-1, Class A-2, Class A-3 and Class A-4 Certificates shall be reduced
on a pro rata basis in accordance with the relative sizes of such Class
Principal Balances, until any such remaining excess is reduced to zero. On each
Distribution Date, following the distributions to Certificateholders to be made
on such date pursuant to Section 4.01, the Class Principal Balance of the Class
RCKB Certificates shall be reduced to the extent necessary (if at all) to equal
the Uncertificated Principal Balance of REMIC I Regular Interest RCKB-2 that
will be outstanding immediately following such Distribution Date. On each
Distribution Date, following the distributing to Certificateholders to be made
on such date pursuant to Section 4.01, the Class Principal Balance of the Class
GLC Certificates shall be reduced to the extent necessary (if at all) to equal
the Uncertificated Principal Balance of REMIC I Regular Interest GLC-2 that will
be outstanding immediately following such Distribution Date. All such reductions
in the Class Principal Balances of the respective Classes of the Principal
Balance Certificates shall constitute allocations of Realized Losses and
Additional Trust Fund Expenses.

          (b) Any and all allocations of Realized Losses and Additional Trust
Fund Expenses to any particular Class of Principal Balance Certificates on any
Distribution Date, in accordance with

                                     -227-

<PAGE>

Section 4.04(a), thereby resulting in an unfunded reduction in the Class
Principal Balance of such Class of Principal Balance Certificates, shall be
deemed to have first been allocated to the Corresponding REMIC II Regular
Interest(s) in respect of such Class of Principal Balance Certificates with a
resulting unfunded reduction in the Uncertificated Principal Balance(s) of such
REMIC II Regular Interest(s) that is equal to the aforementioned unfunded
reduction in the Class Principal Balance of such Class of Principal Balance
Certificates. In the case of any Class of Class A-P&I Certificates, which have
multiple Corresponding REMIC II Regular Interests, such reductions in the
respective Uncertificated Principal Balances of such Corresponding REMIC II
Regular Interests shall be made in numerical order of the last digit in the
respective alphanumeric designations of such Corresponding REMIC II Regular
Interests (for example, A-1-1, A-1-2 and A-1-3, in that order); provided that
(i) in no event shall the Uncertificated Principal Balance of REMIC II Regular
Interest A-1-3 be so reduced at all until the Uncertificated Principal Balances
of REMIC II Regular Interest A-1-1 and REMIC II Regular Interest A-1-2 have been
reduced to zero, and in no event shall the Uncertificated Principal Balance of
REMIC II Regular Interest A-1-2 be so reduced at all until the Uncertificated
Principal Balance of REMIC II Regular Interest A-1-1 has been reduced to zero,
(ii) in no event shall the Uncertificated Principal Balance of REMIC II Regular
Interest A-2-3 be so reduced at all until the Uncertificated Principal Balances
of REMIC II Regular Interest A-2-1 and REMIC II Regular Interest A-2-2 have been
reduced to zero, and in no event shall the Uncertificated Principal Balance of
REMIC II Regular Interest A-2-2 be so reduced at all until the Uncertificated
Principal Balance of REMIC II Regular Interest A-2-1 has been reduced to zero,
(iii) in no event shall the Uncertificated Principal Balance of REMIC II Regular
Interest A-3-3 be so reduced at all until the Uncertificated Principal Balances
of REMIC II Regular Interest A-3-1 and REMIC II Regular Interest A-3-2 have been
reduced to zero, and in no event shall the Uncertificated Principal Balance of
REMIC II Regular Interest A-3-2 be so reduced at all until the Uncertificated
Principal Balance of REMIC II Regular Interest A-3-1 has been reduced to zero,
and (iv) in no event shall the Uncertificated Principal Balance of REMIC II
Regular Interest A-4-2 be so reduced at all until the Uncertificated Principal
Balance of REMIC II Regular Interest A-4-1 has been reduced to zero.

          (c) On each Distribution Date, following the deemed distributions to
be made in respect of the REMIC I Regular Interests pursuant to Section 4.01(l),
the Uncertificated Principal Balance of each REMIC I Regular Interest (after
taking account of such deemed distributions) shall be reduced to the extent
necessary (if at all) to equal the Stated Principal Balance of the related
Pooled Mortgage Loan or Pooled REO Loan, as the case may be (or, if applicable
in cases involving the substitution of multiple Replacement Pooled Mortgage
Loans, the aggregate Stated Principal Balance of each and every related Pooled
Mortgage Loan and/or Pooled REO Loan, as the case may be), that will be
outstanding immediately following such Distribution Date; provided that the
Uncertificated Principal Balance of REMIC I Regular Interest RCKB-2 (after
taking account of such deemed distributions pursuant to Section 4.01(l)) shall
be reduced to the extent necessary (if at all) to equal the excess, if any, of
(i) the Stated Principal Balance of the Ritz-Carlton Key Biscayne Pooled
Mortgage Loan or any successor Pooled REO Loan with respect thereto that will be
outstanding immediately following such Distribution Date, over (ii) the
Uncertificated Principal Balance of REMIC I Regular Interest RCKB-1 (after
taking account of such deemed distributions pursuant to Section 4.01(l)); and
provided further, that the Uncertificated Principal Balance of REMIC I Regular
Interest GLC-2 (after taking account of such deemed distributions pursuant to
Section 4.01(l) shall be reduced to the extent necessary (if at all) to equal
the excess, if any, of (i) the Stated Principal Balance of the Great Lakes
Crossing Pooled Mortgage Loan or any successor Pooled REO Loan with respect
thereto that will be outstanding immediately following such Distribution Date,
over (ii) the Uncertificated Principal Balance of REMIC

                                     -228-

<PAGE>

I Regular Interest GLC-1 (after taking account of such deemed distributions
pursuant to Section 4.01(l)). All such reductions in the Uncertificated
Principal Balances of the respective REMIC I Regular Interests shall be deemed
to constitute allocations of Realized Losses and Additional Trust Fund Expenses.

          (d) On each Distribution Date, following the deemed distributions to
be made in respect of each Loan REMIC Regular Interest pursuant to Section
4.01(m), the Uncertificated Principal Balance of the Loan REMIC Regular Interest
(after taking account of such deemed distributions) shall be reduced to the
extent necessary (if at all) to equal the Stated Principal Balance of the
related Exhibit B-5 Mortgage Loan, any Replacement Pooled Mortgage Loan(s)
substituted for that Exhibit B-5 Mortgage Loan and/or any successor Pooled REO
Loan(s) with respect to the foregoing. All such reductions in the Uncertificated
Principal Balances of any Loan REMIC Regular Interest shall be deemed to
constitute allocations of Realized Losses and Additional Trust Fund Expenses.

          SECTION 4.05. Calculations.

          Provided that the Trustee receives the necessary information from the
Master Servicer and/or the 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
Trustee Reports pursuant to Section 4.02(a) and the actual and deemed
allocations of Realized Losses and Additional Trust Fund Expenses to be made
pursuant to Section 4.04. The Trustee shall calculate the Standard Available
Distribution Amount for each Distribution Date and shall allocate such amount
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 the
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.

                                THE CERTIFICATES

          SECTION 5.01. The Certificates.

          (a) The Certificates shall consist of 27 Classes with the following
respective alphabetic or alphanumeric Class designations: "A-X", "A-SP", "A-1",
"A-2", "A-3", "A-4", "B", "C", "D", "E", "F", "G", "H", "J", "K", "L", "M", "N",
"O", "P", "GLC", "RCKB", "R", "V-1", "V-2", "V-3" and "V-4", 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-5; 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 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, Class
P, Class GLC and Class RCKB 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 Depositary. The Class A-X, Class A-SP, Class A-1, Class A-2, Class A-3,
Class A-4, 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, Class P, Class GLC and Class

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
other REMIC III Regular Interest Certificates will be issuable only in
denominations corresponding to initial Certificate Principal Balances as of the
Closing Date of not less than $100,000 and any whole dollar denomination in
excess thereof. The Class R, Class V-1, Class V-2, Class V-3 and Class V-4
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,

                                     -230-

<PAGE>

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
Avenue, 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 Servicer and the Special Servicer shall have the right to
inspect the Certificate Register or to obtain a copy thereof at all reasonable
times, and to rely conclusively upon a certificate of the Certificate Registrar
as to the information set forth in the Certificate Register.

          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 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 Depositary 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:

                                     -231-

<PAGE>

(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 Servicer, the 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.

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

          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, Class P, Class
GLC or Class RCKB 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 Depositary, Clearstream and/or Euroclear to direct the Trustee
to debit the account of a Depositary Participant by a denomination of interests
in such Rule 144A Global Certificate, and credit the account of a Depositary
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, Class P, Class GLC or Class RCKB Certificates to be
transferred. Upon delivery to the Trustee of such certifications and such orders

                                     -232-

<PAGE>

and instructions, the Trustee, subject to and in accordance with the applicable
procedures of the Depositary, 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, Class P, Class
GLC or Class RCKB 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, 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, Class
P, Class GLC or Class RCKB 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 Depositary, Clearstream
and/or Euroclear to direct the Trustee to debit the account of a Depositary
Participant by a denomination of interests in such Regulation S Global
Certificate, and credit the account of a Depositary 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 E,
Class F, Class G, Class H, Class J, Class K or Class L, Class M, Class N, Class
O, Class P, Class GLC or Class RCKB 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
Depositary, 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, Class P, Class GLC or Class RCKB
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, Class P, Class GLC or Class RCKB
Certificates may be transferred by any Certificate Owner holding such interest
to any Institutional Accredited Investor (other than a Qualified Institutional
Buyer) 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 Depositary,
Clearstream and/or Euroclear to direct the Trustee to debit the account of a
Depositary Participant by the denomination of the transferred interests in such
Global Certificate. Upon delivery to the Certificate Registrar of the

                                     -233-

<PAGE>

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 Depositary, 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 Servicer, the 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.

          (c) No transfer of any Certificate or interest therein shall be made
to any Plan or to any Person who is 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, 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 would result in the
imposition of an excise tax under Section 4975 of the Code.

          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 Depositary 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) 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 (iii) in the case
of a Non-Registered Certificate (other than a Class R, Class V-1, Class V-2,
Class V-3 or Class V-4 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,
Column, KeyBank, the Master Servicer, the Special Servicer, any Sub-Servicer or
any Borrower with respect to Pooled Mortgage Loans constituting more than 5% of
the aggregate unamortized principal balance of all the Pooled 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

                                     -234-

<PAGE>

(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) 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 result in the
imposition of an excise tax under Section 4975 of the Code. 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

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, Column, KeyBank, the
Master Servicer, the Special Servicer, any Sub-Servicer or any Borrower with
respect to Pooled Mortgage Loans constituting more than 5% of the aggregate
unamortized principal balance of all the Pooled 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) 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
result in the imposition of an excise tax under Section 4975 of the Code. 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.

          (d) (i) Each Person who has or acquires any Ownership Interest in a
     Class R 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

                                     -235-

<PAGE>

     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 Certificate are
     expressly subject to the following provisions:

               (A) Each Person holding or acquiring any Ownership Interest in a
          Class R 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 Certificate, the Certificate Registrar shall
          require delivery to it, and shall not register the Transfer of any
          Class R Certificate until its receipt, of an affidavit and agreement
          substantially in the form attached hereto as Exhibit H-1 (a "Transfer
          Affidavit and Agreement"), from the proposed Transferee, 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 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 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 Transfer Affidavit and
          Agreement 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
          Certificate to such proposed Transferee shall be effected.

               (D) Each Person holding or acquiring any Ownership Interest in a
          Class R Certificate shall agree (1) to require a Transfer Affidavit
          and Agreement from any prospective Transferee to whom such Person
          attempts to transfer its Ownership Interest in such Class R
          Certificate and (2) not to transfer its Ownership Interest in such
          Class R 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 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 regulation section
          1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest
          in a Class R Certificate if it is, or is holding an Ownership Interest
          in a Class R Certificate on behalf of, a "pass-through interest
          holder".

               (ii) If any purported Transferee shall become a Holder of a Class
     R Certificate in violation of the provisions of this Section 5.02(d), then
     the last preceding Holder of such Class R 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 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 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
     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 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 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
     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 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 (A) as a
     result of the Transfer of an Ownership Interest in a Class R Certificate to
     any Person who is a Disqualified Organization, including the information
     described in Treasury regulation sections 1.860D-1(b)(5) and 1.860E-2(a)(5)
     with respect to the "excess inclusions" for each Loan REMIC Residual
     Interest, the REMIC I Residual Interest, the REMIC II Residual Interest and
     the REMIC III Residual Interest and (B) as a result of any regulated
     investment company, real estate investment trust, common trust fund,
     partnership, trust, estate or organization described in Section 1381 of the
     Code that holds an Ownership Interest in a Class R Certificate having as
     among its record holders at any time any Person which is a Disqualified
     Organization, 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

                                     -237-

<PAGE>

               Trustee or the Trust), to the effect that doing so will not (1)
               cause any REMIC Pool to cease to qualify as a REMIC or be subject
               to an entity-level tax caused by the Transfer of any Class R
               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 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 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, Class P, Class GLC and Class RCKB
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 Depositary 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 Depositary 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
Depositary; and, except as provided in Section 5.02(b) or Section 5.03(c) below,
such Certificate Owners 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 Depositary Participant or indirect participating brokerage
firm representing each such Certificate Owner. Each Depositary 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 Depositary's normal
procedures.

          (b) Except as expressly provided to the contrary herein, the
Depositor, the Master Servicer, the Special Servicer, 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 Depositary 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 Depositary Participants and indirect participating brokerage firms
representing such Certificate Owners. Multiple requests and directions from, and
votes of, the Depositary 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 Depositary of such record date.

          (c) If (i)(A) the Depositor advises the Trustee and the Certificate
Registrar in writing that the Depositary 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,
or (ii) the Depositor at its option advises the Trustee and the Certificate
Registrar in writing that it elects to terminate the book-entry system through
the Depositary with respect to all or any portion of any Class of Book-Entry
Certificates, the Certificate Registrar shall notify all affected Certificate
Owners, through the Depositary, 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 Depositary,
accompanied by registration instructions from the Depositary 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

                                     -239-

<PAGE>

Depositor, the Master Servicer, the Special Servicer, the Trustee or the
Certificate Registrar shall be liable for any delay in delivery of such
instructions, and each of them 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 5.04, 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 5.04 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 Servicer, the Special Servicer, 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 Servicer, the Special
Servicer, 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

                                     -240-

<PAGE>

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 Depositary, Depositary Participants and/or indirect participating
brokerage firms for which Depositary 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 SERVICER AND THE SPECIAL SERVICER

          SECTION 6.01. Liability of the Depositor, the Master Servicer and the
                        Special Servicer.

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

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

          (a) Subject to Section 6.02(b), the Depositor, the Master Servicer and
the Special Servicer 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 Servicer and the Special
Servicer 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, the Master
Servicer or the Special Servicer shall be a party, or any Person succeeding to
the business of the Depositor, the Master Servicer, or the Special Servicer,
shall be the successor of the Depositor, the Master Servicer or the Special
Servicer, as the case may be, hereunder, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding; provided, however, that no successor or
surviving Person shall succeed to the rights of the Master Servicer or the
Special Servicer unless (i) 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 Master Servicer) or
Section 2.06 (in the case of a successor or surviving Person to the Special
Servicer), as applicable.

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

          None of the Depositor, the Master Servicer or the Special Servicer
shall be under any liability to the Trust, the Trustee, the Certificateholders
or the holder of the Great Lakes Crossing Companion Mortgage Loan for any action
taken or not taken in good faith pursuant to this Agreement or for errors in
judgment; provided, however, that this provision shall not protect the
Depositor, the Master Servicer or the Special Servicer against any liability to
the Trust, the Trustee, the Certificateholders or the holder of the Great Lakes
Crossing Companion Mortgage Loan for the breach of a representation or warranty
made by such party herein, or against any expense or liability specifically
required to be borne

                                      -242-

<PAGE>

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 Servicer or
the Special Servicer 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 Servicer or the Special
Servicer 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, as provided in Section 3.05(a), or the Distribution Account
as provided in Section 3.05(b) or, to the extent permitted by the related A/B
Intercreditor Agreement, out of amounts attributable to an A/B Mortgage Loan
Pair on deposit in the related A/B Mortgage Loan Pair Custodial Account as
provided in Section 3.04(e) or, to the extent permitted by the Great Lakes
Crossing Intercreditor Agreement, out of amounts attributable to the Great Lakes
Crossing Companion Mortgage Loan on deposit in the GLCTML Custodial Account as
provided in Section 3.04(f), against any loss, liability, cost or expense
(including reasonable legal 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 Servicer or the
Special Servicer shall be under any obligation to appear in, prosecute or defend
any legal action unless such action is related to its respective duties under
this Agreement and, 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, the Master Servicer
or the 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 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
Servicer or the Special Servicer, as the case may be, shall be entitled to be
reimbursed therefor from the Collection Account, as provided in Section 3.05(a),
or the Distribution Account as provided in Section 3.05(b) or, to the extent
permitted by the related A/B Intercreditor Agreement, out of amounts
attributable to an A/B Mortgage Loan Pair on deposit in the related A/B Mortgage
Loan Pair Custodial Account as provided in Section 3.04(e) or, to the extent
permitted by the Great Lakes Crossing Intercreditor Agreement, out of amounts
attributable to the Great Lakes Crossing Companion Mortgage Loan on deposit in
the GLCTML Custodial Account as provided in Section 3.04(f).

          In addition, neither the Master Servicer nor the Special Servicer
shall have any liability with respect to, and the Master Servicer and the
Special Servicer shall each 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 the Master Servicer or the Special
Servicer, as the case may be, and conforming to the requirements of this
Agreement. Each of the Master Servicer and the Special Servicer may rely in good
faith on information provided to it by the other such party (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 the Master Servicer and the Special
                        Servicer.

          (a) Each of the Master Servicer and the Special Servicer may resign
from the obligations and duties hereby imposed on it, upon a determination that
its duties hereunder are no longer permissible under applicable law or are in
material conflict by reason of applicable law with any other activities carried
on by it (the other activities of the Master Servicer or the Special Servicer,
as the case may be, so causing such a conflict being of a type and nature
carried on by the Master Servicer or the Special Servicer, as the case may be,
at the date of this Agreement). Any such determination requiring the resignation
of the Master Servicer or the Special Servicer, as applicable, shall be
evidenced by an Opinion of Counsel to such effect which shall be delivered to
the Trustee. Unless applicable law requires the Master Servicer's or the 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 3.25 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 the Master Servicer
or the 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.

          (b) In addition, the Master Servicer and the Special Servicer shall
each 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 the Master Servicer nor the Special Servicer shall be
permitted to resign except as contemplated in subsections (a) and (b) of this
Section 6.04. Consistent with the foregoing, neither the Master Servicer nor the
Special Servicer 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 3.22 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 the Master
Servicer or the Special Servicer are transferred to a successor thereto, the
entire amount of compensation payable to the Master Servicer or the 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 Servicer and the Special Servicer.

          Each of the Master Servicer and the Special Servicer shall afford the
Depositor, the Trustee, the Controlling Class Representative 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

                                      -244-

<PAGE>

request, each of the Master Servicer and the 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. The Master Servicer and the Special Servicer may each 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 Servicer and/or the Special
Servicer hereunder and may, but is not obligated to, perform, or cause a
designee to perform, any defaulted obligation of the Master Servicer and/or the
Special Servicer hereunder or exercise the rights of the Master Servicer and/or
the Special Servicer hereunder; provided, however, that neither the Master
Servicer nor the Special Servicer shall be relieved of any of its obligations
hereunder by virtue of such performance by the Depositor or its designee. The
Depositor shall not have any responsibility or liability for any action or
failure to act by the Master Servicer or the Special Servicer and is not
obligated to supervise the performance of the Master Servicer or the Special
Servicer under this Agreement or otherwise.

          SECTION 6.06. Master Servicer and Special Servicer May Own
                        Certificates.

          The Master Servicer, the Special Servicer or any Affiliate of either
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 the Master Servicer, the Special Servicer or an Affiliate of either
of them. If, at any time during which the Master Servicer, the Special Servicer
or Affiliate of the Master Servicer or the Special Servicer is the Holder of
(or, in the case of a Book-Entry Certificate, Certificate Owner with respect to)
any Certificate, the Master Servicer or the Special Servicer, 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 the Master Servicer's or the Special Servicer's, as the case may
be, reasonable, good faith judgment, violate the Servicing Standard, but that,
if taken, might nonetheless, in the Master Servicer's or the Special Servicer's,
as the case may be, reasonable, good faith judgment, be considered by other
Persons to violate the Servicing Standard, then the Master Servicer or the
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 the Master Servicer or the Special Servicer, as the case may be, or by
an Affiliate thereof and (c) describes in reasonable detail the action that the
Master Servicer or the 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 the Master Servicer and its Affiliates or the
Special Servicer and its Affiliates, as applicable), 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 the Master Servicer or its Affiliates or the 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 the Master Servicer or the Special
Servicer, as the case may be, shall act as proposed in the written notice, such
action shall be

                                      -245-

<PAGE>

deemed to comply with the Servicing Standard. The Trustee shall be entitled to
reimbursement from the Master Servicer or the Special Servicer, as applicable,
for the reasonable expenses of the Trustee incurred pursuant to this paragraph.
It is not the intent of the foregoing provision that the Master Servicer or the
Special Servicer be permitted to invoke the procedure set forth herein with
respect to routine servicing matters arising hereunder, but rather in the case
of unusual circumstances.

                                     DEFAULT

          SECTION 7.01. Events of Default.

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

               (i) any failure by the Master Servicer to deposit into the
     Collection Account, the GLCTML Custodial Account or any A/B Mortgage Loan
     Pair 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 the Special Servicer to deposit into the REO
     Account or to deposit, or remit to the Master Servicer for deposit, into
     the 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 the 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 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 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 the Master Servicer to timely make any
     Servicing Advance required to be made by it hereunder, which Servicing
     Advance remains unmade for a period of three Business Days following the
     date on which notice shall have been given to the Master Servicer by the
     Trustee as provided in Section 3.11(f); or

               (v) any failure by the Special Servicer to timely make (or
     request the 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
     the Special Servicer by the Trustee as provided in Section 3.11(f); or

               (vi) any failure on the part of the Master Servicer or the
     Special Servicer duly to observe or perform in any material respect any
     other of the covenants or agreements on the part of the Master Servicer or
     the Special Servicer, as the case may be, contained in this Agreement,
     which 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 the Master Servicer or the Special Servicer, as
     the case may be, by any other party hereto or to the Master Servicer or the
     Special Servicer, as the case may be, with a copy to each other party
     hereto, by the Controlling Class Representative, the holder of the Great
     Lakes Crossing Companion Mortgage Loan or the Holders of Certificates
     entitled to at least 25% of the Voting Rights; provided that, with respect
     to any such failure that is not curable within such 30-day period the
     Master Servicer or the Special Servicer, as the case may be, shall have an
     additional

                                      -247-

<PAGE>

     cure period of 30 more days to effect such cure so long as the Master
     Servicer or the Special Servicer, as the case may be, has commenced to cure
     such failure within the initial 30-day period and has provided the Trustee
     with an Officer's Certificate certifying that it has diligently pursued,
     and is continuing to pursue, a full cure and such delay does not materially
     or adversely affect the Certificateholders; or

               (vii) any breach on the part of the Master Servicer or the
     Special Servicer of any representation or warranty contained in this
     Agreement that materially and adversely affects the interests of any Class
     of Certificateholders or the holder of the Great Lakes Crossing Companion
     Mortgage Loan and which continues unremedied for a period of 30 days after
     the date on which notice of such breach, requiring the same to be remedied,
     shall have been given to the Master Servicer or the Special Servicer, as
     the case may be, by any other party hereto or to the Master Servicer or the
     Special Servicer, as the case may be, with a copy to each other party
     hereto, by the Controlling Class Representative, the holder of the Great
     Lakes Crossing Companion Mortgage Loan or the Holders of Certificates
     entitled to at least 25% of the Voting Rights; provided that, with respect
     to any such breach that is not curable within such 30-day period, the
     Master Servicer or the Special Servicer, as the case may be, shall have an
     additional cure period of 30 more days to effect such cure so long as the
     Master Servicer or the Special Servicer, as the case may be, has commenced
     to cure such 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 and such delay does not
     materially or adversely affect the Certificateholders; 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
     the Master Servicer or the Special Servicer and such decree or order shall
     have remained in force undischarged, undismissed or unstayed for a period
     of 60 days; or

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

               (xi) the Trustee shall have received written notice from either
     Rating Agency to the effect that the continuation of the Master Servicer or
     the Special Servicer in such capacity (A) would result in a qualification,
     downgrade or withdrawal of one or more ratings assigned by such Rating
     Agency to the Certificates or (B) would result or has resulted in any
     rating assigned

                                      -248-

<PAGE>

     by such Rating Agency to the Certificates otherwise becoming the subject of
     a "negative" credit watch, and in any event such circumstances shall not
     have changed, as confirmed to the Trustee in writing by such Rating Agency,
     within 60 days following the date on which the Trustee first received such
     notice; or

               (xii) one or more ratings assigned by either Rating Agency to the
     Certificates shall have been qualified, downgraded or withdrawn as a result
     of the Master Servicer's or the Special Servicer's acting in such capacity;
     or

               (xiii) the Master Servicer ceases to be rated at least CMS3 by
     Fitch or the Special Servicer ceases to be rated at least CSS3 by Fitch,
     and such rating is not restored within 60 days after the subject downgrade
     or withdrawal.

          When a single entity acts as Master Servicer and Special Servicer, an
Event of Default (other than an event described in clause (xi), (xii) or (xiii)
above) in one capacity shall constitute an Event of Default in both such
capacities.

          (b) If any Event of Default with respect to the Master Servicer or the
Special Servicer (in either case, for purposes of this Section 7.01(b), the
"Defaulting Party") shall occur and be continuing, then, and in each and every
such case, so long as the Event of Default shall not have been remedied, the
Depositor and Trustee each may, and at the written direction of the Holders of
Certificates entitled to not less than 25% of the Voting Rights or at the
written direction of the holder of the Great Lakes Crossing Companion Mortgage
Loan (if such holder is materially and adversely affected by the subject Event
of Default), 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 (other than pursuant
to Section 6.03) and in and to the Mortgage Loans (other than as a Holder of any
Certificate, as the holder of the Great Lakes Crossing Companion Mortgage Loan
or as a B-Note Mortgage Loan Holder). 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
or the Mortgage Loans or otherwise (other than as a Holder of any Certificate,
as the holder of the Great Lakes Crossing Companion Mortgage Loan or as a B-Note
Mortgage Loan Holder), shall pass to and be vested in the Trustee pursuant to
and under this Section 7.01(b), 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 of the
Master Servicer and the 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, as well
as amounts due to it thereafter, if any, including any Excess Servicing Strip
and Work-out Fees, 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). Each of the Master Servicer and the
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

                                      -249-

<PAGE>

thereby to enable the Trustee to assume the Master Servicer's or the Special
Servicer's, as the case may be, functions hereunder, and shall otherwise
cooperate with the Trustee in effecting the termination of the Master Servicer's
or the 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 the Master Servicer to the Collection Account, any A/B Mortgage
Loan Pair Custodial Account, the GLCTML Custodial Account, the Distribution
Account or any Servicing Account or Reserve Account (if it is the Defaulting
Party) or by the Special Servicer to the REO Account, the Collection Account,
any A/B Mortgage Loan Pair Custodial Account, the GLCTML Custodial Account or
any Servicing Account or Reserve Account (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 the Master Servicer and the Special
Servicer each 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, as well as amounts due to it thereafter, if
any, including any Excess Servicing Strip and Work-Out Fees, 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 the Master Servicer or
the Special Servicer pursuant to this paragraph in connection with the
termination thereof shall be borne by the terminated 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 that the Master Servicer or the 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 the Master Servicer or the Special Servicer, as the case may be,
in its capacity as such under this Agreement and the transactions set forth or
provided for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto and arising thereafter placed on the Master
Servicer or the Special Servicer, as the case may be, by the terms and
provisions hereof, including, if the Master Servicer is the resigning or
terminated party, the Master Servicer's obligation to make Advances; provided,
however, that any failure to perform such duties or responsibilities caused by
the Master Servicer's or the Special Servicer's, as the case may be, failure to
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 Pooled 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 (subject to Section 3.11(a) with respect to
the Excess Servicing Strip). 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 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 Special Servicer, as
the case may be, hereunder in the

                                      -250-

<PAGE>

assumption of all or any part of the responsibilities, duties or liabilities of
the resigning or terminated Master Servicer or 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). No appointment of a
successor to the Master Servicer or the 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.

          SECTION 7.03. Notification to Certificateholders.

          (a) Upon any resignation of the Master Servicer or the Special
Servicer pursuant to Section 6.04, any termination of the Master Servicer or the
Special Servicer pursuant to Section 7.01, any appointment of a successor to the
Master Servicer or the Special Servicer pursuant to Section 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.

          (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, 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; and provided, further, that the
holder of the Great Lakes Crossing Companion Mortgage Loan must consent to the
waiver of any Event of Default that materially and adversely affects such holder
and which has not been cured. 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.

                                     -251-

<PAGE>

          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.

                                  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 Servicer, the Special Servicer, 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

                                     -253-

<PAGE>

     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 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 rerecording, refiling
     or redepositing of any thereof, (B) to cause the maintenance of any
     insurance, or (C) to confirm or verify the truth, accuracy or contents of
     any reports or certificates of the Master Servicer, the Special Servicer,
     any actual or prospective 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, Officer's Certificate,
     certificate of auditors or any other certificate, statement, instrument,
     opinion, report, notice, request, consent, order, appraisal, bond or other
     paper or document reasonably believed by it to be genuine and 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,

                                     -254-

<PAGE>

     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
     (except to pay expenses that could reasonably be expected to be incurred in
     connection with the performance of its normal duties and except for any
     expense or liability specifically required to be borne by the Trustee
     pursuant to the terms hereof), 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) 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 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 the Master Servicer or the
     Special Servicer (unless the Trustee is acting as the Master Servicer or
     the Special Servicer, as the case may be) or of the Controlling Class
     Representative or 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

                                     -255-

<PAGE>

     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 Depositary or between or among Depositary 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 Pooled 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 or any Fiscal Agent Agreement, 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 Pooled 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 Pooled Mortgage
Loans to the Trust, or any funds (other than funds held by the Trustee in an
account maintained thereby) deposited in or withdrawn from the Collection
Account or any other account by or on behalf of the Depositor, the Master
Servicer or the Special Servicer (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 the Master
Servicer or the Special Servicer, and the Master Servicer or the Special
Servicer, as the case may be, would be so responsible hereunder. Except as
expressly contemplated in Section 11.02, the Trustee shall not be required to
record this Agreement.

          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 Pooled Mortgage Loans and any Pooled REO

                                     -256-

<PAGE>

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 Pooled Mortgage Loan and Pooled REO Loan, the
Trustee's Fee shall accrue during each calendar month, commencing with April
2003, at the Trustee's Fee Rate on a principal amount equal to the Stated
Principal Balance of such Pooled Mortgage Loan or Pooled REO Loan immediately
following the Distribution Date in such calendar month (or, in the case of April
2003, on a principal amount equal to the Cut-off Date Principal Balance of the
particular Pooled Mortgage Loan), whether or not interest is actually collected
on each Pooled Mortgage Loan and Pooled REO Loan. With respect to each Pooled
Mortgage Loan and Pooled REO Loan, the Trustee's Fee shall accrue from time to
time on the same Interest Accrual Basis as is applicable to such Pooled Mortgage
Loan or Pooled REO 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.

          (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 Pooled Mortgage Loans (unless it incurs
any such expense or liability in the capacity of 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 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
regulation 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 negligent disregard of, the Trustee's
obligations and duties hereunder.

          (c) Each of the Master Servicer and the 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 the Master
Servicer's or the Special Servicer's, as the case may be, negligent acts or
omissions in connection with this Agreement, including the negligent use by the
Master Servicer or the 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 the Master Servicer or the 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.

                                     -257-

<PAGE>

          (d) Each of the Trustee and any Fiscal Agent shall indemnify the
Master Servicer and the Special Servicer 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 the Master Servicer
or the 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, the Master
Servicer or the 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 8.06 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. 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 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 "Baa2" from Moody's and "BBB" from 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, Column, KeyBank, the Master Servicer, the 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) the Master Servicer or the Special Servicer (except during any
period when the Trustee has assumed the duties of the Master Servicer or the
Special Servicer, as the case may be, pursuant to Section 7.02), (iv) Column,
(v) KeyBank or (vi) any Affiliate of any of them, may be the Trustee hereunder.

<PAGE>

          SECTION 8.07. Resignation and Removal of Trustee.

          (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Master Servicer, the Special Servicer, all the Certificateholders, the holder of
the Great Lakes Crossing Companion Mortgage Loan and the B-Note Mortgage Loan
Holders. Upon receiving such notice of resignation, the Depositor shall promptly
appoint a successor trustee 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 the other parties hereto, to the Certificateholders, to the
holder of the Great Lakes Crossing Companion Mortgage Loan and to the B-Note
Mortgage Loan Holders by the successor trustee. If no successor trustee shall
have been so appointed and have accepted appointment within 30 days after the
giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor trustee.

          (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Depositor or the Master Servicer or if at any
time the Trustee shall become incapable of acting, or shall be adjudged bankrupt
or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, or if the Trustee'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 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, the
Certificateholders, the holder of the Great Lakes Crossing Companion Mortgage
Loan and the B-Note Mortgage Loan Holders by the successor trustee.

          (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 Servicer and the
Special Servicer), 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, the holder of the
Great Lakes Crossing Companion Mortgage Loan and the B-Note Mortgage 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 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

                                     -259-

<PAGE>

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 Servicer, the
Special Servicer 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 Servicer, the Special Servicer
and the predecessor trustee shall execute and deliver such instruments and do
such other things as may reasonably be required to more fully and certainly vest
and confirm in the successor trustee all such rights, powers, duties and
obligations, and to enable the successor trustee to perform its obligations
hereunder.

          (b) No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06.

          (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, the Certificateholders, the holder
of the Great Lakes Crossing Companion Mortgage Loan and the B-Note Mortgage 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 Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
8.10, such powers, duties, obligations, rights and trusts as the Master Servicer
and the Trustee may consider necessary or desirable. If the Master Servicer
shall not have joined in such appointment within 15 days

                                     -260-

<PAGE>

after the receipt by it of a request to do so, or in case an Event of Default in
respect of the Master Servicer shall have occurred and be continuing, the
Trustee alone shall have the power to make such appointment. No co-trustee or
separate trustee hereunder shall be required to meet the terms of eligibility as
a successor trustee under Section 8.06, 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 Master Servicer or 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 Master Servicer and
the 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 depositary 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, Column, KeyBank or any Affiliate of the Depositor, Column or
KeyBank, 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

                                     -261-

<PAGE>

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 Servicer,
the Special Servicer, the Controlling Class Representative, the Class RCKB

holder of the Great Lakes Crossing Companion Mortgage Loan, each B-Note Mortgage

related A/B Intercreditor Agreement, any B-Note Mortgage Loan Holder, access to

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

Directing Certificateholder, each B-Note Mortgage Loan Holder (to the extent
required under the related A/B Intercreditor Agreement), the holder of the Great
Lakes Crossing Companion Mortgage Loan and, subject to the succeeding paragraph,

                                     -262-

<PAGE>

Trustee (all Appraisals of Mortgaged Properties and/or REO Properties shall, in
each case, be delivered to the Trustee by the Master Servicer or the Special
Servicer, as applicable, promptly following the subject Appraisal's having been
obtained or formulated); (xi) any and all Officer's Certificates and other

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, 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 Servicer, and within a
reasonable period following its receipt of such request, the Master Servicer
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, the Master Servicer or the 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 Fitch (or, in the case of either Rating Agency, such lower
rating as will not result in an

                                     -263-

<PAGE>

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 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 2.07. 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 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 Servicer or the Special Servicer.

          (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

                                     -264-

<PAGE>

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 any other
subsequent fiscal year for the Trust, if as of the beginning of such other
subsequent 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 Depositary) by at least 300 Holders and/or Depositary Participants
having accounts with the Depositary, or if reporting under the Exchange Act is
required during or for, as applicable, such fiscal year because the Trustee
failed to make the requisite filing suspending such reporting), the Trustee
shall:

               (i) with respect to each Distribution Date 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 on behalf of the Trust and properly
     and timely file with the Commission monthly, with respect to the Trust, a
     Current Report on Form 8-K, which shall include as an exhibit a copy of the
     Trustee Report disseminated by the Trustee on such Distribution Date and
     such other items as the Depositor may reasonably request;

               (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(c) (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 on behalf of the Trust
     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;

               (iii) at the reasonable request of, and in accordance with the
     reasonable directions of, any other party hereto, prepare for filing and
     promptly file with the Commission an amendment to any Current Report on
     Form 8-K previously filed with the Commission with respect to the Trust;
     and

               (iv) prepare 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 Officer's Certificates and Accountant's
     Statements delivered pursuant to Section 3.13 and Section 3.14,
     respectively, with respect to the Master Servicer and the Special Servicer
     for such fiscal year, and which shall further include such certification(s)
     as may be required under the Sarbanes-Oxley Act of 2002 and any rules
     promulgated by, or

                                     -265-

<PAGE>

     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 (or readily convertible to a format suitable for) electronic filing
via the EDGAR system (including "ASCII", "Microsoft Excel" (solely in the case
of reports from the Master Servicer or the Special Servicer pursuant to Section
3.12), "Microsoft Word" 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 or readily convertible to such format)
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 in the format required for (or readily convertible
to a format suitable for) electronic filing via the EDGAR system (including
"ASCII", "Microsoft Excel" (solely in the case of reports from the Master
Servicer or the Special Servicer pursuant to Section 3.12), "Microsoft Word" 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).

          (b) All Annual Reports on Form 10-K with respect to the Trust shall
include any certification (the "Sarbanes-Oxley Certification") required to be
included therewith pursuant to the Sarbanes-Oxley Act of 2002, 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 Servicer, the Special Servicer 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 M hereto (with
respect to the Master Servicer and the Trustee) or in the form set forth on
Exhibit A to Exhibit M hereto (with respect to the Special Servicer), 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 M hereto shall relate
to distribution information, and the Master Servicer's certification with
respect to items 4 and 5 of Exhibit M hereto shall relate to servicing
information. 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 addition, if directed by the Depositor, such Performing Party
shall provide an identical certification to Depositor's certified public
accountants that such Performing Party provided to its own

                                     -266-

<PAGE>

certified public accountants to the extent such certification relates to the
performance of such Performing Party's duties pursuant to this Agreement or a
modified certificate limiting the certification therein to the performance of
such Performing Party's duties pursuant to this Agreement. 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(b) with respect to the period of
time such Performing Party was subject to this Agreement.

          (c) 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, or if reporting
under the Exchange Act is required during or for, as applicable, any other
fiscal year because the Trustee failed to make the requisite filing suspending
such reporting, 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 Pooled
     Mortgage Loan or an REO Property, 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, Pooled
     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

                                     -267-

<PAGE>

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(c) unless
such Responsible Officer was notified in writing.

          (d) If as of the beginning of any fiscal year for the Trust (other
than fiscal year 2003), the Registered Certificates are held (directly or, in
the case of Registered Certificates held in book-entry form, through the
Depositary) by less than 300 Holders and/or Depositary Participants having
accounts with the Depositary, 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

part of such Performing Party in the performance of its obligations otherwise
hereunder. A Performing Party shall have no obligation to indemnify any

          (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

or otherwise, any additional information relating to the Mortgage Loans, the

          (i) The Master Servicer and the Special Servicer may make available

in the case of a Rating Agency, at the expense of the requesting party, to the
Depositor, the Trustee, the Rating Agencies, any Certificateholder, any

therein and any other Persons to whom the Master Servicer or the Special

Section 8.14(i) shall be deemed or construed to otherwise limit the obligations
of the Master Servicer and the Special Servicer under this Agreement to deliver
to any Person any of the items set forth in clauses (i) through (iv) above.

          (j) Notwithstanding the obligations of the Master Servicer and the
Special Servicer set forth in the preceding two subsections of this Section
8.14, the Master Servicer and the Special Servicer may withhold 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 Servicer or
the Master Servicer has determined that such withholding is appropriate.

          (k) Notwithstanding anything to the contrary in this Agreement, as a
condition to the Master Servicer or Special Servicer making any report or
information available upon request to any Person other than the parties hereto,
the Master Servicer and Special Servicer may require that the recipient of such
information acknowledge that the Master Servicer and Special Servicer may
contemporaneously provide such information to the Depositor, the Trustee, the
Underwriters, any Rating Agency, the Certificateholders and/or the Certificate
Owners. Each of the Master Servicer and the 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 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, the 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 the 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 the
Master Servicer for any liability or damage that may arise therefrom. Any
transmittal of information by the Master Servicer or Special Servicer to any
Person other than the Trustee, the Rating Agencies or the Depositor shall be
accompanied by a letter from the 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

                                   TERMINATION

          SECTION 9.01. Termination Upon Repurchase or Liquidation of All Pooled
                        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 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 the Master Servicer,
the Special Servicer or any single Controlling Class Certificateholder or group
of Controlling Class Certificateholders of all Pooled 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 Pooled Mortgage Loans
remaining in the Trust Fund (exclusive of any Pooled REO 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 Special
Servicer and approved by the Trustee and the Master Servicer, minus (C) if the
purchaser is the Master Servicer or the 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 (including Excess Servicing Strip) to such Person (which
items shall be deemed to have been paid or reimbursed to the Master Servicer or
the Special Servicer, as the case may be, in connection with such purchase);
(ii) the exchange by the Sole Certificateholder(s) of all the Certificates for
all Pooled Mortgage Loans and each REO Property remaining in the Trust Fund; and
(iii) the final payment or other liquidation (or any advance with respect
thereto) of the last Pooled 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 Master Servicer or the Special
Servicer, in that order of preference, may at its option elect to purchase all
the Pooled 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 the Master Servicer or
the 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 desires to purchase all of the Pooled
Mortgage Loans and any REO Properties remaining in the Trust Fund, preference
shall be given to the Controlling Class Certificateholder or group of
Controlling Class Certificateholders with the largest Percentage Interest in the
Controlling Class. If the Trust is to be terminated in connection with the
purchase of all the Pooled Mortgage Loans and each REO Property remaining in the
Trust Fund by the Master Servicer, the Special Servicer or any Controlling Class
Certificateholder(s), such Person(s) shall: (i) deliver to the Master Servicer
for

                                     -271-

<PAGE>

deposit (or, if the Master Servicer is the purchaser, it shall deposit) in the
Collection Account (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; 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 Master Servicer shall transfer to the
Distribution Account all amounts required to be transferred by it to such
account on such Master Servicer Remittance Date from the Collection Account
pursuant to the first paragraph of Section 3.04(b), together with any other
amounts on deposit in the Collection Account that would otherwise be held for
future distribution. Upon confirmation that the deposit of the Termination Price
has been made to the Collection Account 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 Pooled 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 remaining
Pooled 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 Pooled 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 Pooled 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 second Business Day
prior to the Distribution Date on which the final distribution on the
Certificates is to occur, shall deposit in the Collection Account an amount in
immediately available funds equal to all amounts then due and owing to the
Depositor, the Master Servicer, the Special Servicer, the Trustee and/or any
Fiscal Agent hereunder that may be withdrawn from the Collection Account,
pursuant to Section 3.05(a), or that may be withdrawn from the Distribution
Account pursuant to Section 3.05(b), but only to the extent that such amounts
are not already on deposit in the Collection Account. In addition, the Master
Servicer shall transfer to the Distribution Account all amounts required to be
transferred by it to such account on such Master Servicer Remittance Date from
the 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 Pooled 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 remaining Pooled Mortgage Loans and REO Properties to the Sole
Certificateholder(s) (or any designee thereof).

          (c) Notice of any termination shall be given promptly by the Trustee
by letter to Certificateholders mailed (x) if such notice is given in connection
with the purchase of all the Pooled Mortgage Loans and each REO Property
remaining in the Trust Fund by the Master Servicer, the Special Servicer 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

                                     -272-

<PAGE>

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, the holder of the
Great Lakes Crossing Companion Mortgage Loan and the B-Note Mortgage Loan
Holders at the time such notice is given to Certificateholders.

          (d) 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 on
deposit in the Distribution Account that is allocable to payments on the
relevant Class in accordance with Section 4.01. Any funds not distributed to any
Holder or Holders of Certificates of any Class on the Final Distribution Date
because of the failure of such Holder or Holders to tender their Certificates
shall, on such date, be set aside and held uninvested in trust and credited to
the account or accounts of the appropriate non-tendering Holder or Holders. If
any Certificates as to which notice has been given pursuant to this Section 9.01
shall not have been surrendered for cancellation within six months after the
time specified in such notice, the Trustee shall mail a second notice to the
remaining non-tendering Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If
within one year after the second notice all such Certificates shall not have
been surrendered for cancellation, the Trustee, directly or through an agent,
shall take such reasonable steps to contact the remaining non-tendering
Certificateholders concerning the surrender of their Certificates as it shall
deem appropriate. The costs and expenses of holding such funds in trust and of
contacting such Certificateholders following the first anniversary of the
delivery of such second notice to the non-tendering Certificateholders shall be
paid out of such funds. No interest shall accrue or be payable to any former
Holder on any amount held in trust hereunder. If by the second anniversary of
the delivery of such second notice, all of the Certificates shall not have been
surrendered for cancellation, then, subject to applicable escheat laws, the
Trustee shall distribute to the Class R Certificateholders all unclaimed funds
and other assets which remain subject hereto.

          SECTION 9.02. Additional Termination Requirements.

          (a) If the Master Servicer, the Special Servicer or a Controlling
Class Certificateholder purchases, or the Sole Certificateholder(s) exchange all
of the Certificates for, all the Pooled Mortgage Loans and each REO Property
remaining in the Trust Fund as provided in Section 9.01, the Trust and each
REMIC Pool shall be terminated in accordance with the following additional
requirements, unless the purchasing party obtains at its own expense and
delivers to the Trustee an Opinion of Counsel, addressed to the Trustee, to the
effect that the failure of the Trust to comply with the requirements of this
Section 9.02 will not result in an Adverse REMIC Event with respect to any REMIC
Pool:

               (i) the Trustee shall specify the first day in the 90-day
     liquidation period in a statement attached to the final Tax Return for each
     REMIC Pool, pursuant to Treasury regulation section 1.860F-1 and shall
     satisfy all requirements of a qualified liquidation under Section 860F of
     the Code and any regulations thereunder (as evidenced by an Opinion of
     Counsel to such effect delivered on behalf and at the expense of the
     purchasing party);

                                     -273-

<PAGE>

               (ii) during such 90-day liquidation period and at or prior to the
     time of making the final payment on the Certificates, the Trustee shall
     sell or otherwise transfer all the Pooled Mortgage Loans and each REO
     Property remaining in the Trust Fund to the applicable Person, in exchange
     for cash and/or Certificates in accordance with Section 9.01; and

               (iii) immediately following the making of the final payment on
     the Certificates, the Trustee shall distribute or credit, or cause to be
     distributed or credited, to the Holders of the Class R Certificates all
     remaining cash on hand (other than cash retained to meet claims), and each
     REMIC Pool shall terminate at that time.

          (b) By their acceptance of Certificates, the Holders hereby authorize
the Trustee to prepare and adopt, on behalf of the Trust, a plan of complete
liquidation of each REMIC Pool in accordance with the terms and conditions of
this Agreement, which authorization shall be binding upon all successor
Certificateholders.

                            ADDITIONAL TAX PROVISIONS

          SECTION 10.01. Tax Administration.

          (a) The Trustee shall elect to treat each REMIC Pool as a REMIC under
the Code and, if necessary, under applicable state law. Each such election will
be made on IRS Form 1066 or other appropriate federal tax or information return
or any appropriate state Tax Returns for the taxable year ending on the last day
of the calendar year in which the Certificates are issued.

          (b) The Plurality Class R Certificateholder is hereby designated as
the Tax Matters Person of each REMIC Pool and, in such capacity, shall be
responsible to act on behalf of such REMIC Pool in relation to any tax matter or
controversy, to represent such REMIC Pool in any administrative or judicial
proceeding relating to an examination or audit by any governmental taxing
authority, to request an administrative adjustment as to any taxable year of
such REMIC Pool, to enter into settlement agreements with any governmental
taxing agency with respect to such REMIC Pool, to extend any statute of
limitations relating to any tax item of such REMIC Pool and otherwise to act on
behalf of such REMIC Pool in relation to any tax matter or controversy involving
such REMIC Pool; provided that the Trustee is hereby irrevocably appointed and
agrees to act (in consultation with the Tax Matters Person for each REMIC Pool)
as agent and attorney-in-fact for the Tax Matters Person for each REMIC Pool in
the performance of its duties as such. The legal expenses and costs of any
action described in this Section 10.01(b) and any liability resulting therefrom
shall be expenses, costs and liabilities of the Trust payable out of amounts on
deposit in the Distribution Account as provided by Section 3.05(b) unless such
legal expenses and costs are incurred by reason of a Tax Matters Person's or the
Trustee's misfeasance, bad faith or negligence in the performance of, or such
Person's negligent disregard of, its obligations or are expressly provided by
this Agreement to be borne by any party hereto.

          (c) The Trustee shall prepare or cause to be prepared, execute and
file all of the Tax Returns in respect of each REMIC Pool (other than Tax
Returns required to be filed by the Master Servicer and/or the Special Servicer
pursuant to Section 3.09(g)) and all of the applicable income tax and other
information returns for each Grantor Trust Pool. The expenses of preparing and
filing such returns shall be borne by the Trustee without any right of
reimbursement therefor.

          (d) The Trustee shall perform on behalf of each REMIC Pool all
reporting and other tax compliance duties that are the responsibility of such
REMIC Pool under the Code, the REMIC Provisions or other compliance guidance
issued by the IRS or any state or local taxing authority. Included among such
duties, the Trustee shall provide: (i) to any Transferor of a Class R
Certificate, such information as is necessary for the application of any tax
relating to the transfer of a Class R Certificate to any Person who is not a
Permitted Transferee; (ii) to the Certificateholders, such information or
reports as are required by the Code or the REMIC Provisions, including reports
relating to interest, original issue discount and market discount or premium
(using the Prepayment Assumption as required); and (iii) to the IRS, the name,
title, address and telephone number of the Person who will serve as the
representative of each REMIC Pool.

          (e) The Trustee shall take such action and shall cause each REMIC Pool
to take such action as shall be necessary to create or maintain the status
thereof as a REMIC under the REMIC

                                     -275-

<PAGE>

Provisions (and the other parties hereto shall assist it, to the extent
reasonably requested by the Trustee), to the extent that the Trustee has actual
knowledge that any particular action is required; provided that the Trustee
shall be deemed to have knowledge of relevant tax laws. The Trustee shall not
knowingly take or fail to take any action, or cause any REMIC Pool to take or
fail to take any action, that under the REMIC Provisions, if taken or not taken,
as the case may be, could result in an Adverse REMIC Event in respect of any
REMIC Pool or an Adverse Grantor Trust Event with respect to any Grantor Trust
Pool, unless the Trustee has received an Opinion of Counsel to the effect that
the contemplated action or non-action, as the case may be, will not result in an
Adverse REMIC Event or an Adverse Grantor Trust Event. None of the other parties
hereto shall take or fail to take any action (whether or not authorized
hereunder) as to which the Trustee has advised it in writing that it has
received an Opinion of Counsel to the effect that an Adverse REMIC Event or an
Adverse Grantor Trust Event could occur with respect to such action. In
addition, prior to taking any action with respect to any REMIC Pool or the
assets thereof, or causing any REMIC Pool to take any action, which is not
contemplated by the terms of this Agreement, each of the other parties hereto
will consult with the Trustee, in writing, with respect to whether such action
could cause an Adverse REMIC Event or an Adverse Grantor Trust Event to occur,
and no such other party shall take any such action or cause any REMIC Pool to
take any such action as to which the Trustee has advised it in writing that an
Adverse REMIC Event or an Adverse Grantor Trust 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 permitted by this
Agreement.

          (f) If any tax is imposed on any REMIC Pool, including "prohibited
transactions" taxes as defined in Section 860F(a)(2) of the Code, any tax on
"net income from foreclosure property" as defined in Section 860G(c) of the
Code, any taxes on contributions to any REMIC Pool after the Startup Day
pursuant to Section 860G(d) of the Code, and any other tax imposed by the Code
or any applicable provisions of state or local tax laws (other than any tax
permitted to be incurred by the Special Servicer on behalf of the Trust pursuant
to Section 3.17(a)), then such tax, together with all incidental costs and
expenses (including penalties and reasonable attorneys' fees), shall be charged
to and paid by: (i) the Trustee, if such tax arises out of or results from a
breach of any of its obligations under Article IV, Article VIII or this Article
X; (ii) any Fiscal Agent, if such tax arises out of or results from a breach of
any of its obligations under Article IV or this Article X; (iii) the Master
Servicer, if such tax arises out of or results from a breach by the Master
Servicer of any of its obligations under Article III or this Article X; (iv) the
Special Servicer, if such tax arises out of or results from a breach by the
Special Servicer of any of its obligations under Article III or this Article X;
or (v) the Trust, out of the Trust Fund (exclusive of the Grantor Trust Pools),
in all other instances. If any tax is imposed on any Grantor Trust Pool, such
tax, together with all incidental costs and expenses (including, without
limitation, penalties and reasonable attorneys' fees), shall be charged to and
paid by: (i) the Special Servicer, if such tax arises out of or results from a
breach by the Special Servicer of any of its obligations under Article III or
this Article X; (ii) the Master Servicer, if such tax arises out of or results
from a breach by the Master Servicer of any of its obligations under Article III
or this Article X; (iii) the Trustee, if such tax arises out of or results from
a breach by the Trustee of any of its obligations under Article IV, Article VIII
or this Article X; (iv) any Fiscal Agent, if such tax arises out of or results
from a breach of any of its obligations under Article IV or this Article X; or
(v) the Trust, out of the portion of the Trust Fund constituting such Grantor
Trust Pool, in all other instances. Consistent with the foregoing, any tax
permitted to be incurred by the Special Servicer pursuant to Section 3.17(a)
shall be charged to and paid by the Trust. Any such amounts payable by the Trust
in respect of taxes shall be paid by the Trustee out of amounts on deposit in
the Distribution Account.

          (g) The Trustee and, to the extent that records are maintained thereby
in the normal course of its business, each of the other parties hereto shall,
for federal income tax purposes, maintain books and records with respect to each
REMIC Pool and each Grantor Trust Pool on a calendar year and an accrual basis.

          (h) Following the Startup Day for each REMIC Pool, the Trustee shall
not (except as contemplated by Section 2.03) accept any contributions of assets
to any REMIC Pool unless it shall have received an Opinion of Counsel (at the
expense of the party seeking to cause such contribution) to the effect that the
inclusion of such assets in such REMIC Pool will not result in an Adverse REMIC
Event in respect of such REMIC Pool or an Adverse Grantor Trust Event with
respect to any Grantor Trust Pool.

          (i) None of the Master Servicer, the Special Servicer, the Trustee or
any Fiscal Agent shall consent to or, to the extent it is within the control of
such Person, permit: (i) the sale or disposition of any Pooled Mortgage Loan
(except in connection with (A) a Breach or Document Defect with respect to a
Pooled Mortgage Loan, (B) the foreclosure, default or reasonably foreseeable
material default of a Pooled Mortgage Loan, including the sale or other
disposition of a Mortgaged Property acquired by foreclosure, deed in lieu of
foreclosure or otherwise, (C) the bankruptcy of any REMIC Pool, or (D) the
termination of the Trust pursuant to Article IX of this Agreement); (ii) the
sale or disposition of any investments in any Investment Account for gain; or
(iii) the acquisition of any assets for the Trust (other than a Mortgaged
Property acquired through foreclosure, deed in lieu of foreclosure or otherwise
in respect of a defaulted Pooled Mortgage Loan, other than a Replacement Pooled
Mortgage Loan substituted for a Deleted Mortgage Loan and other than Permitted
Investments acquired in connection with the investment of funds in an Investment
Account or an interest in a single member limited liability company, as provided
in Section 3.16); in any event unless it has received an Opinion of Counsel (at
the expense of the party seeking to cause such sale, disposition, or
acquisition) to the effect that such sale, disposition, or acquisition will not
result in an Adverse REMIC Event in respect of any REMIC Pool or an Adverse
Grantor Trust Event with respect to any Grantor Trust Pool.

          (j) Except as otherwise permitted by Section 3.17(a), none of the
Master Servicer, the Special Servicer or the Trustee shall enter into any

Institutional Buyer that takes delivery 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

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

<PAGE>

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 the subject 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

Person that takes delivery in the form of an 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 Depositary Participant by a denomination of interests
in this Regulation S Global Certificate, and credit the account of a Depositary
Participant by a denomination of interests in the related 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 the
subject 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 Depositary 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,
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.

          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class [A-X] [A-SP] Certificates under the
Securities Act or any other securities law or to take any action not otherwise
required under the Agreement to permit the transfer of this Certificate or any
interest herein without registration or qualification. Any Certificateholder or
Certificate Owner desiring to effect a transfer of this Certificate or any
interest herein shall, and does hereby agree to, indemnify CSFB LLC, the
Depositor, the Trustee, any Fiscal Agent, the Master Servicer, the Special
Servicer and the Certificate Registrar against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws or the provisions described in the preceding paragraphs.

          No transfer of this Certificate or any interest herein shall be made

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
(and, if applicable, any Certificate Owner shall refuse to transfer an interest
in 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 to the effect that the purchase and holding of this 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 (iii) if
this Certificate is rated investment grade by at least one of the Rating
Agencies and is being acquired by, on behalf of or with assets of a Plan in
reliance upon Prohibited Transaction Exemption 89-90, 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, Column, KeyBank,
any Exemption-Favored Party, the Master Servicer, the Special Servicer, any
Sub-Servicer or any Borrower with respect to Mortgage Loans constituting more
than 5% of the aggregate unamortized principal of all the Mortgage Loans
determined as of the Closing Date, or by an Affiliate of any 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)
a certification of facts and an Opinion of Counsel which otherwise establish to
the reasonable satisfaction of the Trustee (or, if 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 Code.

          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
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,
Master Servicer, the 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 other than a Qualified
Institutional Buyer that takes delivery other than in the form of an interest in
this Rule 144A Global Certificate.

<PAGE>

          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 Depositary Participant by a denomination of interests in this Rule 144A
Global Certificate, and credit the account of a Depositary 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 the
subject 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 that takes delivery in the form of an 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 Depositary Participant by a denomination of interests
in this Regulation S Global Certificate, and credit the account of a Depositary
Participant by a denomination of interests in the related 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 the
subject 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

                                      A-3-5

<PAGE>

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 Depositary 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,
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.

          None of the Depositor, the Trustee or the Certificate Registrar is
obligated to register or qualify the Class [F] [G] [H] [J] [K] [L] [M] [N] [O]
[P] [GLC] [RCKB] Certificates under the Securities Act or any other securities
law or to take any action not otherwise required under the Agreement to permit
the transfer of this Certificate or any interest herein without registration or
qualification. Any Certificateholder or Certificate Owner desiring to effect a
transfer of this Certificate or any interest herein shall, and does hereby agree
to, indemnify the Depositor, CSFB LLC, the Trustee, any Fiscal Agent, the Master
Servicer, the Special Servicer and the Certificate Registrar against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws or the provisions described in the
preceding paragraphs.

          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
(and, if applicable, any Certificate Owner shall refuse to transfer an interest
in 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 to the effect that the purchase and holding of this 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 (iii) if
this Certificate is rated investment grade by at least one of the Rating
Agencies and is being acquired by, on behalf of or with assets of a Plan in
reliance upon Prohibited Transaction Exemption 89-90, 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, Column, KeyBank,
any Exemption-Favored Party, the Master Servicer, the Special Servicer, any
Sub-Servicer or any Borrower with respect to Mortgage Loans constituting more
than 5% of the aggregate unamortized principal of all the Mortgage Loans
determined as of the Closing Date, or by an Affiliate of any such Person, and
(Z) agrees that it will obtain from each of its Transferees a

                                      A-3-6

<PAGE>

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) a certification of facts and an Opinion of Counsel which
otherwise establish to the reasonable satisfaction of the Trustee (or, if
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
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.

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

          The Depositor, the Master Servicer, the Special Servicer, the Trustee,
any Fiscal Agent, the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the 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
Master Servicer, the 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 earliest 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
Master Servicer, the 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)

                                      A-3-7

<PAGE>

the exchange of all the Certificates for all the Mortgage Loans and each REO
Property remaining in the Trust Fund. The Agreement permits, but does not
require, the Master Servicer, the Special Servicer, or 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 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 Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and 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 (subject to certain third-party beneficiary consent
rights). 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.

Class in authorized denominations evidencing the same aggregate Percentage

Certificate or any interest herein shall, and does hereby agree to, indemnify
the Depositor, Credit Suisse First Boston LLC, the Trustee, any Fiscal Agent,
the Master Servicer, the Special Servicer, and the Certificate Registrar against

requirements of the Securities Act and any applicable state securities laws or
is not made in accordance with such federal and state laws.

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

imposition of an excise tax under Section 4975 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.

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 Master Servicer, the Special Servicer, the Trustee,
any Fiscal Agent, the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the Special Servicer, the Trustee, any Fiscal Agent or the
Certificate Registrar may treat the Person in whose name this Certificate is

Master Servicer, the Special Servicer, the Trustee, any Fiscal Agent, the
Certificate Registrar or any such agent shall be affected by notice to the

          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 earliest 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
Master Servicer, the 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 exchange of all the
Certificates for all the Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer, or 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 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 Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and 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 (subject to certain third-party beneficiary consent
rights). 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.

the Trust Fund evidenced by all the Class R Certificates. The Trust Fund was
created and the Certificates were issued pursuant to that certain pooling and
servicing agreement, dated as of April 11, 2003 (the "Agreement"), among Credit
Suisse First Boston Mortgage Securities Corp., as depositor (the "Depositor",
which term includes any successor entity under the Agreement), KeyCorp Real
Estate Capital Markets, Inc. d/b/a KeyBank Real Estate Capital, as master
servicer and special servicer (in such capacities, the "Master Servicer" and
"Special Servicer", respectively, each of which terms includes any successor
entity under the Agreement), and Wells Fargo Bank Minnesota, N.A., as trustee
(the "Trustee", which term includes any successor entity under the Agreement), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, 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
immediately preceding the month of such distribution (the "Record Date"), in an
amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to all the Holders of the
Class R Certificates on the applicable Distribution Date pursuant to the
Agreement. All distributions made under the Agreement on this Certificate will
be made by the Trustee by wire transfer of immediately available funds to the
account of the Person entitled thereto at a bank or other entity having
appropriate facilities therefor, if such Certificateholder shall have provided
the Trustee with 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 distributions), or otherwise by check mailed to the address of
such Certificateholder as it appears in the Certificate Register.
Notwithstanding the foregoing, the final distribution on this Certificate will
be made in like manner, but only upon presentation and surrender of this
Certificate at the offices of the Certificate Registrar or such other location
specified in the notice to the Holder hereof of such final distribution.

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

          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

                                      A-5-3

<PAGE>

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
Master Servicer, the Special Servicer, the Trustee or the Certificate Registrar
in their respective capacities as such), together with the written
certification(s) as to the facts surrounding such transfer from the
Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based. 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 LLC, the
Trustee, any Fiscal Agent, the Master Servicer, the 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

                                      A-5-4

<PAGE>

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, a Non-United States Tax Person or a foreign permanent
establishment or fixed base (each within the meaning of the applicable income
tax treaty) of a United States Tax Person (as defined below). 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

                                      A-5-5

<PAGE>

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 other than a 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 political subdivision
thereof, 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 Tax 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 Master Servicer, the Special Servicer, the Trustee,
any Fiscal Agent, the Certificate Registrar and any agent of the Depositor, the
Master Servicer, the 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
Master Servicer, the 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 earliest 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
Master Servicer, the Special Servicer, or any single Controlling Class

                                      A-5-6

<PAGE>

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 exchange of all the
Certificates for all the Mortgage Loans and each REO Property remaining in the
Trust Fund. The Agreement permits, but does not require, the Master Servicer,
the Special Servicer, or 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 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 Master Servicer, the Special Servicer, the Trustee and any Fiscal
Agent and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Master Servicer, the Special Servicer, the Trustee and 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 (subject to certain third-party beneficiary consent
rights). 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.

          Re:  Credit Suisse First Boston Mortgage Securities Corp., Commercial
               Mortgage Pass-Through Certificates, Series 2003-CK2

Ladies and Gentlemen:

          Pursuant to Section 2.02(b) of the Pooling and Servicing Agreement
dated as of April 11, 2003 and related to the above-referenced Certificates (the
"Agreement"), Wells Fargo Bank Minnesota, N.A. as trustee (the "Trustee"),
hereby certifies as to each Original Pooled Mortgage Loan subject to the
Agreement (except as specifically identified in the exception report attached
hereto) that: (i) the original Mortgage Note specified in clause (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 certifying that the
original of such Mortgage Note has been lost), the original or copy of documents
specified in clauses (ii) through (v) and (vii) of the definition of "Mortgage
File" and, in the case of a hospitality property, the documents specified in
clause (viii) of the definition of "Mortgage File" (without regard to the
parenthetical), and any other Specially Designated Mortgage Loan Documents, have
been received by it or a Custodian on its behalf; (ii) if this certification is
more than 180 days after the Closing Date, the recordation/filing contemplated
by Section 2.01(e) of the Agreement has been completed (based solely on receipt
by the Trustee of the particular recorded/filed documents or an appropriate
receipt of recording/filing therefor); (iii) all documents received by it or any
Custodian with respect to such Pooled 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 Pooled Mortgage Loan; and (iv) 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 Pooled
Mortgage Loan Schedule with respect to the items specified in clause (iii)(a) of
the definition of "Pooled Mortgage Loan Schedule" accurately reflects the
information set forth in the related Mortgage File.

          None of the Trustee, the Master Servicer, the Special Servicer, or any
Custodian is under any duty or obligation to inspect, review or examine any of
the documents, instruments, certificates or other papers relating to the Pooled
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. Furthermore, none of the Trustee, the Master Servicer, the 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

                                     B-4-1

<PAGE>

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 (i) through (v), in clause (vii) and, in
the case of any Pooled Mortgage Loan secured by a Mortgage on a hospitality
property, in clause (viii) of the definition of "Mortgage File" and any other
Specially Designated Mortgage Loan Documents, have been received and such
additional information as will be necessary for delivering the certifications
required by the Agreement.

          Further, with respect to UCC filings, absent actual knowledge or
copies of UCC filings in the Mortgage File indicating otherwise, the Trustee
shall make the assumptions contemplated by the second paragraph of Section
2.02(a) of the Agreement.

          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.

(1) Debt Service Coverage Ratios are updated periodically as new NOI figures
become available from borrowers on an asset level. In all cases, the most
current DSCR provided by the Servicer is used.To the extent that no DSCR is
provided by the Servicer, information from the offering document is used. The
Trustee makes no representations as to the accuracy of the data provided by the
borrower for this calculation.

(2) Anticipated Remaining Term and WAM are each calculated based upon the term
from the current month to the earlier of the Anticipated Repayment Date, if
applicable, and the maturity date.

(3) Data in this table was calculated by allocating pro-rata the current loan
information to the properties based upon the Cut-off Date Balance of the related
mortgage loan as disclosed in the offering document.

Note:(i) "Scheduled Balance" has the meaning assigned thereto in the CMSA
Standard Information Package.

          Re:  Credit Suisse First Boston Mortgage Securities Corp., Commercial
               Mortgage Pass-Through Certificates, Series 2003-CK2, Class ______
               Certificates [having an initial aggregate Certificate [Principal
               Balance] [Notional Amount] as of April 11, 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 that certain pooling
and servicing agreement dated as of April 11, 2003 (the "Pooling and Servicing
Agreement"), among Credit Suisse First Boston Mortgage Securities Corp., as
depositor, KeyCorp Real Estate Capital Markets, Inc. d/b/a KeyBank Real Estate
Capital, as master servicer and special servicer (in such capacities, the
"Master Servicer" and "Special Servicer", respectively), 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

                                     F-1A-1

<PAGE>

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:

                                     F-1A-2

<PAGE>

          (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 Pooled Mortgage Loans, (d) the Pooling
and Servicing Agreement, and (e) all related matters, that the Transferee has
requested.

                                               Very truly yours,

          ______________________________________________________________________

          3. For purposes of determining the aggregate amount of securities

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.

<PAGE>

          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.

          ___    ___    Will the Transferee be purchasing the Transferred
          Yes    No     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.

            QUALIFIED INSTITUTIONAL BUYER STATUS UNDER SEC RULE 144A

          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").

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

          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,

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.

          ___   ___        Will the Transferee be purchasing the Transferred
          Yes   No         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 undersigned will notify the parties to which this certification
is made of any changes in the information and conclusions herein. Until such
notice, the Transferee's purchase of the Transferred Certificates will
constitute a reaffirmation of this certification by the undersigned as of the
date of such purchase.

          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.

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

Certificates or any other similar security.

Certificates; the Transferee has sought such accounting, legal and tax advice as
it has considered necessary to make an informed investment decision; and the

     ___  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.

          ____   ____   Will the Transferee be acquiring interests in the
          Yes    No     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.

            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)

                                     F-2C-6

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.

          ____   ____   Will the Transferee be acquiring interests in the
          Yes    No     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.

transferred in transactions which are exempt from such registration and
qualification.

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-CK2, 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, domestic partnership whose beneficial interests are not all held by
United States Persons (as defined below) or a foreign permanent establishment or
fixed based (each within the meaning of an applicable tax treaty) of a 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

                                      H-1-1

<PAGE>

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. In addition,
the Transferee will honor all the restrictions set forth herein upon any
subsequent transfers of the Class R Certificates.

          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. 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.

          10. In accordance with Treasury Regulation Section 1.860E-1 [check the
statement that applies]:

               (a) The consideration paid to the Transferee for accepting the
     Class R Certificates is greater than the present value of the anticipated
     net federal income taxes and tax benefits ("Tax Liability Present Value")
     associated with owning such Certificates, with such present value computed
     using a discount rate equal to the "federal short-term rate" prescribed by
     Section 1274 of the Code as of the date hereof or, to the extent it is not,
     the Transferee has regularly borrowed, in the ordinary course of its trade
     or business, substantial funds from unrelated third parties at a lower
     interest rate than such applicable federal rate and the consideration paid
     to the Transferee is greater than the Tax Liability Present Value using
     such lower interest rate as the discount rate and the transactions in
     question with unrelated third party lenders, the interest rate or rates,
     the date or dates of such transactions, and the maturity dates or,

                                      H-1-2

<PAGE>

     in the case of adjustable rate debt instruments, the relevant adjustment
     dates or periods, with respect to such borrowings, are accurately reflected
     in Exhibit A to this letter;          _______

          or

               (b) the Transferee (i) is an "eligible corporation" as defined in
     Section 1.860E-1(c)(6)(i) of the Treasury Regulations, as to which the
     income of the Residual Interest Certificates will only be subject to
     taxation in the United States, (ii) has, and has had in each of its two
     preceding fiscal years, gross assets for financial reporting purposes
     (excluding any obligation of a person related to the transferee within the
     meaning of Section 1.860E-1(c)(6)(i) of the Treasury Regulations or any
     other assets if a principal purpose for holding or acquiring such other
     assets is to satisfy this condition) in excess of $100 million and net
     assets of $10 million, and (iii) hereby agrees only to transfer the
     Certificate to another corporation meeting the criteria set forth in this
     letter. _______

          11. The Transferee will not cause the income from the Residual
Interest certificate to be attributed to a foreign permanent establishment or
fixed base.

          12. 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.

          For purposes of this affidavit, a "United States 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
political subdivision thereof, 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.

               Certificates, evidencing a ____% Percentage Interest in such
               Class (the "Residual Interest Certificates")

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 that certain pooling and
servicing agreement dated as of April 11, 2003 (the "Pooling and Servicing
Agreement"), among Credit Suisse First Boston Mortgage Securities Corp., as
depositor, KeyCorp Real Estate Capital Markets, Inc. d/b/a KeyBank Real Estate
Capital, as master servicer and special servicer (in such capacities, the
"Master Servicer" and "Special Servicer", respectively), 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.

                                      H-2-1

<PAGE>

          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 conducted such an investigation.

                                      Very truly yours,

OTHER MORTGAGE LOAN DOCUMENT. IN ADDITION, THE REFERENCES HEREIN TO SECURITIES,
INSTRUMENTS AND OTHER OBLIGATIONS SHOULD NOT BE CONSTRUED AS A CONCLUSION THAT
ANY SUCH SECURITY, INSTRUMENT OR OTHER OBLIGATION IS NOT AN INSTRUMENT, A
CERTIFICATED SECURITY OR AN UNCERTIFICATED SECURITY WITHIN THE MEANING OF THE
UNIFORM COMMERCIAL CODE, AS IN EFFECT IN ANY APPLICABLE JURISDICTION, NOR SHOULD
THIS FINANCING STATEMENT BE CONSTRUED AS A CONCLUSION THAT A FILING IS NECESSARY
TO PERFECT THE OWNERSHIP OR SECURITY INTEREST OF THE SECURED PARTY IN THE
CONTRACTUAL RIGHT TO PAYMENT, INCLUDING, WITHOUT LIMITATION, THE RIGHT TO
PAYMENTS OF PRINCIPAL AND INTEREST AND THE RIGHT TO ENFORCE THE RELATED PAYMENT
OBLIGATIONS, ARISING FROM OR UNDER ANY SUCH SECURITY, INSTRUMENT OR OTHER

RESPECT TO THE FOREGOING, THIS FILING IS MADE ONLY IN THE EVENT OF CONTRARY
ASSERTIONS BY THIRD PARTIES.

                                      [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 Pooling and Servicing Agreement dated
as of April 11, 2003 (the "Pooling and Servicing Agreement") among Credit Suisse
First Boston Mortgage Securities Corp., as depositor, Keycorp Real Estate
Capital Markets, Inc. d/b/a Key Commercial Mortgage, as master servicer and
special servicer and Wells Fargo Bank Minnesota, N.A., as trustee. (the
"Document"). Credit Suisse First Boston Corporation, Goldman, Sachs & Co. and
McDonald Investments Inc. (collectively, the "Underwriters") are

["Underwriter/Placement Agent"]

                                      P-1

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 April 11, 2003 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.

                                      P-2
<PAGE>

         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.]

         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

                                    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

         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

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

         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

                                      P-4

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

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:

         9. Issuer represents: [NOTE: ISSUER MUST REPRESENT ONE OF THE
FOLLOWING, AND SHALL CROSS OUT THE OTHER.] The amount of interest payable with
respect to the interest-bearing classes of the series 2003-CK2 certificates on
any distribution date will be a function of the interest accrued during the

distribution date will be the calendar month immediately preceding the month in
which that distribution date occurs.

         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.

principal-and-interest payments shall be received by Cede & Co., as nominee of

(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

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.

                                      P-6
<PAGE>

         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
self-regulatory 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

                                      P-7
<PAGE>

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.

                                      P-12
<PAGE>

         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.

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 Pooling and Servicing
Agreement dated as of April 11, 2003 (the "Pooling and Servicing Agreement")
among Credit Suisse First Boston Mortgage Securities Corp., as depositor,
Keycorp Real Estate Capital Markets, Inc. d/b/a Key Commercial Mortgage, as
master servicer and special servicer and Wells Fargo Bank Minnesota, N.A., as
trustee. (the "Document"). Credit Suisse First Boston Corporation, Goldman,
Sachs & Co. and McDonald Investments Inc. (collectively, the "Underwriters") are

                                      P-15

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 April 11, 2003 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.

                                      P-16
<PAGE>

         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.]

         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:

                                    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

         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

                                    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

                                      P-18

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

         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
dollar amount per $1,000 original face value (or other minimum authorized
denomination if less than $1,000 face value) payable on each payment date
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:

                                    Manager, Announcements

                                    New York, NY 10041-0099

         9. Issuer represents: [NOTE: ISSUER MUST REPRESENT ONE OF THE
FOLLOWING, AND SHALL CROSS OUT THE OTHER.] The amount of interest payable with
respect to the interest-bearing classes of the series 2003-CK2 certificates on
any distribution date will be a function of the interest accrued during the
related interest accrual period. The interest accrual period for any
distribution date will be the calendar month immediately preceding the month in
which that distribution date occurs.

         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.

principal-and-interest 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

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.

                                      P-20
<PAGE>

         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
self-regulatory 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

                                      P-21

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

                        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.

                                      P-27
<PAGE>

         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.

                                      P-28
<PAGE>

         [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.

  REPRESENTATIONS FOR SECURITIES ELIGIBLE FOR TRANSFER PURSUANT TO REGULATION S
       WHERE ISSUER HAS REQUESTED A TEMPORARY "CHILL" ON DELIVER ORDERS--
                 TO BE INCLUDED IN DTC LETTER OF REPRESENTATIONS
                 -----------------------------------------------

         Issuer has requested that, with respect to the Securities that are
eligible for transfer pursuant to Regulation S, which have been identified by a
separate CUSIP number (the "Regulation S Securities"), DTC not effect book-entry
deliveries (except deliveries via DTC's Deposit/Withdrawal at Custodian DWAC
system in Participant accounts maintained by banks that act as depositaries for
Cedel and Euroclear) until ____________________________ [, or--if not
specified--until further notice in the manner set forth below].

         In the event that Issuer desires an extension or shortening of this
"Deliver Order Chill," Issuer or Agent(1) shall send DTC a notice requesting
that the Deliver Order Chill be eliminated as of a specified 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 two
business days prior to the date specified for elimination of the Deliver Order
Chill. If sent by telecopy, such notice shall be sent to (212) 344-1531 or (212)
855-3728. Issuer or Agent shall confirm DTC's receipt of such telecopy by
telephoning DTC's Underwriting Department at (212) 855-3731. If delivered by
hand or sent by mail or overnight delivery, such notice shall be sent to:

                   REPRESENTATIONS FOR RULE 144A SECURITIES--
                 TO BE INCLUDED IN DTC LETTER OF REPRESENTATIONS
                 -----------------------------------------------

         1. Issuer represents that at the time of initial registration in the
name of DTC's nominee, Cede & Co., the Securities were Legally or Contractually
Restricted Securities,(1) eligible for transfer under Rule 144A under the
Securities Act of 1933, as amended (the "Securities Act"), and identified by a
CUSIP or CINS number assigned to any securities of the same class that were not
Legally or Contractually Restricted Securities. Issuer shall ensure that a CUSIP
or CINS identification number is obtained for all unrestricted securities of the
same class that is different from any CUSIP or CINS identification number
assigned to a Legally or Contractually Restricted Security of such class, and
shall notify DTC promptly in the event that it is unable to do so. Issuer
represents that it has agreed to comply with all applicable information
requirements of Rule 144A.

         2. Issuer represents that the Securities are: [NOTE: ISSUER MUST
REPRESENT ONE OF THE FOLLOWING, AND SHALL CROSS OUT THE OTHER.] [included within
PORTAL, a Self-Regulatory Organization System approved by the Securities and
Exchange Commission for the reporting of quotation and trade information of
securities eligible for transfer pursuant to Rule 144A) an "SRO Rule 144A
System").]

         3. If the Securities are not Investment-Grade Securities, Issuer and
Agent acknowledge that if such Securities cease to be included in an SRO Rule
144A System during any period in which such Securities are Legally or
Contractually Restricted Securities, such Securities shall no longer be eligible
for DTC's services. Furthermore, 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 any of the aforementioned
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 DTC Participant ("Participant") having Securities
credited to its DTC accounts.

         4. Issuer and Agent acknowledge that, so long as Cede & Co. is a record
owner of the Securities, Cede & Co. shall be entitled to all applicable voting
rights and receive the full amount of all distributions payable with respect
thereto. Issuer and Agent acknowledge that DTC shall treat any Participant
having Securities credited to its DTC accounts as entitled to the full benefits
of ownership of such Securities. Without limiting the generality of the
preceding sentence, Issuer and Agent acknowledge that DTC shall treat any
Participant having Securities credited to its DTC accounts as entitled to
receive distributions (and voting rights, if any) in respect of the Securities,
and to receive from DTC certificates evidencing Securities. Issuer and Agent
recognize 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 any of the provisions: (a) of Rule 144A; (b) of other
exemptions from registration under the Securities Act or any other state or
federal securities laws; or (c) of the offering documents.

------------------------
      (1) A "Legally Restricted Security" is a security that is a restricted
security, as defined in Rule 144(a)(3). A "Contractually Restricted Security" is
a security that upon issuance and continually thereafter can only be sold
pursuant to Regulation S under the Securities Act, Rule 144A, Rule 144, or in a
transaction exempt from the registration requirements of the Securities Act
pursuant to Section 4 of the Securities Act and not involving any public
offering; provided, however, that once the security is sold pursuant to the
provisions of Rule 144, including Rule 144(k), it will thereby cease to be a
"Contractually Restricted Security." For purposes of this definition, in order
for a depositary receipt to be considered a "Legally or Contractually Restricted
Security," the underlying security must also be a "Legally or Contractually
Restricted Security."

                                                               EXECUTION VERSION

                        MORTGAGE LOAN PURCHASE AGREEMENT

          This Mortgage Loan Purchase Agreement (this "Agreement"), is dated and
effective as of March 27, 2003, between Column Financial, Inc., a Delaware
corporation ("Column"), as seller (in such capacity, together with its
successors and permitted assigns hereunder, the "Seller"), and Credit Suisse
First Boston Mortgage Securities Corp., a Delaware corporation ("CSFB Mortgage
Securities"), as purchaser (in such capacity, together with its successors and
permitted assigns hereunder, the "Purchaser").

                                    RECITALS

          Column desires to sell, assign, transfer, set over and otherwise
convey to CSFB Mortgage Securities, without recourse, and CSFB Mortgage
Securities desires to purchase, subject to the terms and conditions set forth
herein, the multifamily and commercial mortgage loans (collectively, the
"Exhibit A-1 Loans") identified on the schedule annexed hereto as Exhibit A-1,
as such schedule may be amended from time to time pursuant to the terms hereof.

          Column also desires to sell, assign, transfer, set over and otherwise
convey to CSFB Mortgage Securities, without recourse, and CSFB Mortgage
Securities desires to purchase, subject to the terms and conditions set forth
herein, the multifamily and commercial mortgage loans (collectively, the
"Exhibit A-2 Loans" and, collectively with the Exhibit A-1 Loans, the "Mortgage
Loans") identified on the schedule annexed hereto as Exhibit A-2 (together with
the schedule annexed hereto as Exhibit A-1, the "Mortgage Loan Schedule"), as
such schedule may be amended from time to time pursuant to the terms hereof.
Column acquired each of the Exhibit A-2 Loans from KeyBank National Association
("KeyBank") in December 2002. The mortgage loan purchase agreement whereby
Column acquired the Exhibit A-2 Loans from KeyBank is herein referred to as the
"Other MLPA". It is expected that KeyBank will be responsible for making certain
representations and warranties with respect to the Exhibit A-2 Loans in lieu of
the Seller's making the same.

          CSFB Mortgage Securities intends to create a trust (the "Trust"), the
primary assets of which will be a segregated pool of multifamily and commercial
mortgage loans that includes the Mortgage Loans. Beneficial ownership of the
assets of the Trust (such assets collectively, the "Trust Fund") will be
evidenced by a series of mortgage pass-through certificates (the
"Certificates"). Certain classes of the Certificates will be rated by Fitch,
Inc., and Moody's Investors Service, Inc. (together, the "Rating Agencies"). The
Trust will be created and the Certificates will be issued pursuant to a pooling
and servicing agreement dated as of April 11, 2003 (the "Pooling and Servicing
Agreement"), among CSFB Mortgage Securities, as depositor, KeyCorp Real Estate
Capital Markets, Inc. d/b/a KeyBank Real Estate Capital, as master servicer and
special servicer, and Wells Fargo Bank Minnesota, N.A., as trustee. Capitalized
terms used but not otherwise defined herein shall have the respective meanings
assigned to them in the Pooling and Servicing Agreement as in full force and
effect on the Closing Date (as defined in Section 1 hereof). It is anticipated
that CSFB Mortgage Securities

<PAGE>

will transfer the Mortgage Loans to the Trust contemporaneously with its
purchase of the Mortgage Loans hereunder.

          CSFB Mortgage Securities intends to sell certain classes of the
Certificates (collectively, the "Publicly Offered Certificates") to Credit
Suisse First Boston LLC ("CSFB LLC"), Goldman, Sachs & Co. and McDonald
Investments Inc. (collectively in such capacity, the "Underwriters"), pursuant
to an underwriting agreement dated as of March 27, 2003 (the "Underwriting
Agreement), among CSFB Mortgage Securities and the Underwriters, and CSFB
Mortgage Securities intends to sell certain classes of the remaining
Certificates (the "Privately Offered Certificates") to CSFB LLC, pursuant to a
certificate purchase agreement dated as of March 27, 2003 (the "Certificate
Purchase Agreement"), between CSFB Mortgage Securities and the CSFB LLC. The
Publicly Offered Certificates are more fully described in a prospectus dated
March 27, 2003 (the "Basic Prospectus"), and the supplement to the Basic
Prospectus dated March 27, 2003 (the "Prospectus Supplement" and, together with
the Basic Prospectus, the "Prospectus"), as each may be amended or supplemented
at any time hereafter. The Privately Offered Certificates are more fully
described in a confidential offering circular dated March 27, 2003 (the
"Confidential Offering Circular"), as it may be amended or supplemented at any
time hereafter.

          Column will indemnify CSFB Mortgage Securities, CSFB LLC, the other
Underwriters and certain related parties with respect to the disclosure
regarding the Exhibit A-1 Loans contained in the Prospectus, the Confidential
Offering Circular and certain other disclosure documents and offering materials
relating to the Certificates, pursuant to an indemnification agreement dated as
of March 27, 2003 (the "Indemnification Agreement"), among Column, CSFB Mortgage
Securities, CSFB LLC and the other Underwriters.

          NOW, THEREFORE, in consideration of the premises and the mutual
agreements set forth herein, the parties agree as follows:

          SECTION 1. Agreement to Purchase. The Seller agrees to sell, assign,
transfer, set over and otherwise convey to the Purchaser, without recourse, and
the Purchaser agrees to purchase from the Seller, subject to the terms and
conditions set forth herein, the Mortgage Loans. The purchase and sale of the
Mortgage Loans shall take place on April 11, 2003 or such other date as shall be
mutually acceptable to the parties hereto (the "Closing Date"). As of the close
of business on the respective Due Dates for the Mortgage Loans in April 2003
(individually and collectively, the "Cut-off Date"), the Mortgage Loans will
have an aggregate principal balance, after application of all payments of
principal due on the Mortgage Loans on or before the Cut-off Date, whether or
not received, of $835,429,760, subject to a variance of plus or minus 5%. The
consideration for the Mortgage Loans shall be cash in the amount of 101.7% of
such aggregate principal balance of the Mortgage Loans, together with accrued
interest on the Mortgage Loans at their respective Net Mortgage Rates from and
including the Cut-off Date to but not including the Closing Date, which cash
amount the Purchaser shall pay to the Seller on the Closing Date by wire
transfer in immediately available funds or by such other method as shall be
mutually acceptable to the parties hereto.

                                      -2-

<PAGE>

          SECTION 2. Conveyance of the Mortgage Loans.

          (a) Effective as of the Closing Date, subject only to receipt of the
consideration referred to in Section 1 hereof, the Seller does hereby sell,
assign, transfer, set over and otherwise convey to the Purchaser, without
recourse, all of the right, title and interest of the Seller in and to the
Mortgage Loans, including all interest and principal received on or with respect
to the Mortgage Loans after the Cut-off Date (other than scheduled payments of
interest and principal due on or before the Cut-off Date), together with all of
the right, title and interest of the Seller in and to the proceeds of any
related title, hazard or other insurance policies and any escrow, reserve or
other comparable accounts related to the Mortgage Loans.

          (b) The Purchaser shall be entitled to receive all scheduled payments
of principal and interest due on the Mortgage Loans after the Cut-off Date, and
all other recoveries of principal and interest collected thereon after the
Cut-off Date (other than scheduled payments of principal and interest due on the
Mortgage Loans on or before the Cut-off Date and collected after the Cut-off
Date, which shall belong to (and, upon receipt by the Purchaser, if applicable,
shall be delivered to) the Seller).

          (c) On or before the Closing Date, the Seller shall, at its expense,
subject to Section 18 hereof, deliver to and deposit with, or cause to be
delivered to and deposited with, the Purchaser or its designee the Mortgage File
and any Additional Collateral (other than reserve funds and escrow payments)
with respect to each Mortgage Loan. In addition, with respect to each Mortgage
Loan, as to which any Additional Collateral is in the form of a Letter of Credit
as of the Closing Date, the Seller shall 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, and/or to re-issue, to the Purchaser or its designee the
Seller's rights as the beneficiary thereof and drawing party thereunder. The
designated recipient of the items described in the first sentence of this
paragraph, and the designated beneficiary under each Letter of Credit referred
to in the second sentence of this paragraph, shall be the Trustee. The Purchaser
hereby acknowledges that the assignment and/or re-issue process will require the
Seller to deliver each original Letter of Credit to the issuing entity and the
Purchaser hereby agrees that the Seller shall have up to forty-five (45) days to
complete each such assignment and/or re-issue; provided, however, that if the
Master Servicer determines to make a draw under any such Letter of Credit before
the assignment and/or re-issue has been completed, then the Seller will
cooperate with the Master Servicer in making the presentation and draw on the
Letter of Credit and, if necessary, shall make such presentation and draw in its
own name pursuant to the written instructions of the Master Servicer and shall
deliver the proceeds thereof to the Master Servicer for the benefit of the
Trust. If such a draw is not honored as a result of the assignment and/or
re-issue process being incomplete, the Seller shall be liable to the Trust for
all expenses, damages or losses, including, but not limited to, reimbursement of
interest charged by the Master Servicer for any Advance made in lieu of the such
draw, up to an amount not to exceed the amount of such draw, plus Advance
Interest, and related expenses resulting from the failure of the draw to be so
honored.

          If the Seller cannot deliver on the Closing Date any original or
certified recorded document or original policy of title insurance which is to be
delivered as part of the related

                                      -3-

<PAGE>

Mortgage File for any Mortgage Loan solely because the Seller is delayed in
making such delivery by reason of the fact that such original or certified
recorded document has not been returned by the appropriate recording office or
such original policy of title insurance has not yet been issued, then the Seller
shall deliver such documents to the Purchaser or its designee, promptly upon the
Seller's receipt thereof.

          In addition, the Seller shall, at its expense, deliver to and deposit
with, or cause to be delivered to and deposited with, the Purchaser or its
designee, on or before the Closing Date, the following items (except to the
extent that any of the following items are to be retained by a subservicer that
will continue to act on behalf of the Purchaser or its servicing agent): (i)
originals or copies of all financial statements, appraisals,
environmental/engineering reports, leases, rent rolls, third-party underwriting
reports, insurance policies, legal opinions, tenant estoppels and any other
documents that the Purchaser or its servicing agent reasonably deems necessary
to service the subject Mortgage Loan in the possession or under the control of
the Seller that relate to the Mortgage Loans and, to the extent they are not
required to be a part of a Mortgage File for any Mortgage Loan, originals or
copies of all documents, certificates and opinions in the possession or under
the control of the Seller that were delivered by or on behalf of the related
Borrowers in connection with the origination of the Mortgage Loans (provided
that the Seller shall not be required to deliver any attorney-client privileged
communication or any other documents or materials prepared by the Seller or its
affiliates solely for internal credit analysis and other internal uses); and
(ii) all unapplied reserve funds and escrow payments in the possession or under
the control of the Seller that relate to the Mortgage Loans. The designated
recipient of the items described in clauses (i) and (ii) of the preceding
sentence shall be the Master Servicer.

          In connection with the foregoing paragraphs of this Section 2(c), the
Seller is a designated recipient, or shall otherwise be the beneficiary, of all
certifications relating to the Mortgage Loans made and/or delivered by the
Trustee pursuant to Section 2.02(a) and Section 2.02(b) of the Pooling and
Servicing Agreement. To the extent that those certifications and/or the related
exception reports reflect Document Defects with respect to the Mortgage Loans,
those certifications and/or the related exception reports shall constitute
notice to the Seller for purposes of Section 5 upon receipt thereof by the
Seller.

          (d) The Seller shall be responsible for all reasonable fees and
out-of-pocket costs and expenses associated with recording and/or filing any and
all assignments and other instruments of transfer with respect to the Mortgage
Loans that are required to be recorded or filed, as the case may be, under the
Pooling and Servicing Agreement; provided that the Seller shall not be
responsible for actually recording or filing any such assignments or other
instruments of transfer. If the Seller receives written notice that any such
assignment or other instrument of transfer is lost or returned unrecorded or
unfiled, as the case may be, because of a defect therein, the Seller shall
prepare or cause the preparation of a substitute therefor or cure such defect,
as the case may be; provided that the cost of such preparation shall be borne by
the Purchaser if the loss or return is caused by the Purchaser's negligence. The
Seller shall provide the Purchaser or its designee with a power of attorney to
enable it or them to record any loan documents with respect to the Mortgage
Loans that the Purchaser has been unable to record.

                                      -4-

<PAGE>

Unless the Purchaser notifies the Seller in writing to the contrary, the
designated recipients of the power of attorney referred to in the preceding
sentence shall be the Trustee.

          (e) Upon sale of Certificates representing at least 10% of the total
fair value of all the Certificates to unaffiliated third parties, the Seller
shall, under generally accepted accounting principles ("GAAP"), report its
transfer of the Mortgage Loans to the Purchaser, as provided herein, as a sale
of the Mortgage Loans to the Purchaser in exchange for the consideration
specified in Section 1 hereof. In connection with the foregoing, upon sale of
Certificates representing at least 10% of the total fair value of all the
Certificates to unaffiliated third parties, the Seller shall cause all of its
financial and accounting records to reflect such transfer as a sale (as opposed
to a secured loan). Regardless of its treatment of the transfer of the Mortgage
Loans to the Purchaser under GAAP, the Seller 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 to clearly
reflect that the Mortgage Loans have been transferred to the Purchaser and are
no longer available to satisfy claims of the Seller's creditors.

          (f) After the Seller's transfer of the Mortgage Loans to the
Purchaser, as provided herein, the Seller shall not take any action inconsistent
with the Purchaser's ownership of the Mortgage Loans. Except for actions that
are the express responsibility of another party hereunder or under the Pooling
and Servicing Agreement, and further except for actions that the Seller is
expressly permitted to complete subsequent to the Closing Date, the Seller
shall, on or before the Closing Date, take all actions required under applicable
law to effectuate the transfer of the Mortgage Loans by the Seller to the
Purchaser.

          (g) The Mortgage Loan Schedule, as it may be amended from time to
time, shall conform to the requirements set forth in the Pooling and Servicing
Agreement. The Seller shall, within 15 days of its discovery or receipt of
notice of any error on the Mortgage Loan Schedule, amend such Mortgage Loan
Schedule and deliver to the Purchaser or the Trustee, as the case may be, an
amended Mortgage Loan Schedule.

          SECTION 3. Examination of Mortgage Loan Files and Due Diligence
Review. The Seller shall reasonably cooperate with any examination of the
Mortgage Files for, and any other documents and records relating to, the
Mortgage Loans, that may be undertaken by or on behalf of the Purchaser prior to
the Closing Date. The fact that the Purchaser has conducted or has failed to
conduct any partial or complete examination of any of the Mortgage Files for,
and/or any of such other documents and records relating to, the Mortgage Loans,
shall not affect the Purchaser's right to pursue any remedy available in equity
or at law for a breach of the Seller's representations and warranties made
pursuant to Section 4 hereof (subject, however, to Section 5(d)).

          SECTION 4. Representations, Warranties and Covenants of the Seller and
the Purchaser.

          (a) The Seller hereby makes, as of the Closing Date, to and for the
benefit of the Purchaser, each of the representations and warranties set forth
in Exhibit B-1 hereto. The

                                      -5-

<PAGE>

Purchaser hereby makes, as of the Closing Date, to and for the benefit of the
Seller, each of the representations and warranties set forth in Exhibit B-2
hereto.

          (b) The Seller hereby makes, as of the Closing Date (or as of such
other date specifically provided in the particular representation or warranty),
to and for the benefit of the Purchaser, with respect to each Exhibit A-1 Loan,
each of the representations and warranties set forth in Exhibit C hereto.

          In addition, the Seller hereby makes, as of the Closing Date (or as of
such other date specifically provided in the particular representation or
warranty), to and for the benefit of the Purchaser, with respect to each Exhibit
A-2 Loan, as follows:

          (i) Immediately prior to the transfer of the Exhibit A-2 Loans to the
     Purchaser pursuant to this Agreement (and assuming that KeyBank transferred
     to the Seller good title to each Exhibit A-2 Loan free and clear of any and
     all pledges, liens, charges, security interests, participation interests
     and/or other interests and encumbrances, except for certain servicing
     rights of an affiliate of KeyBank), the Seller had good title to, and was
     the sole owner of, each Exhibit A-2 Loan and, further, has full right,
     power and authority to sell, transfer and assign each Exhibit A-2 Loan to,
     or at the direction of, the Purchaser, free and clear of any and all
     pledges, liens, charges, security interests, participation interests and/or
     other interests and encumbrances created by or through the Seller, except
     for certain servicing rights of an affiliate of KeyBank.

          (ii) Subject to the completion of names and addresses of the assignees
     and endorsees and any missing recording information in all instruments of
     transfer or assignment and endorsements and the completion of all recording
     and filing contemplated hereby and/or by the Pooling and Servicing
     Agreement, the Seller will have validly and effectively conveyed to the
     Purchaser all of the Seller's right, title and interest in and to the
     Exhibit A-2 Loans, free and clear of any and all pledges, liens, charges,
     security interests, participation interests and/or other interests and
     encumbrances created by or through the Seller, except for certain servicing
     rights of an affiliate of KeyBank.

          (iii) The sale of the Seller's right, title and interest in and to the
     Exhibit A-2 Loans to the Purchaser or its designee, as contemplated hereby,
     does not require the Seller to obtain any governmental or regulatory
     approval or consent that has not been obtained.

          (iv) Assuming that each Mortgage Note in respect of an Exhibit A-2
     Loan was properly endorsed by KeyBank as directed by the Seller, then each
     Mortgage Note in respect of an Exhibit A-2 Loan is properly endorsed in
     blank.

          (c) The Seller hereby represents and warrants, as of the Closing Date,
to and for the benefit of CSFB Mortgage Securities only, that the Seller has not
dealt with any broker, investment banker, agent or other person (other than the
CSFB Mortgage Securities, CSFB LLC and the other Underwriters) who may be
entitled to any commission or compensation in connection with the sale to the
Purchaser of the Mortgage Loans.

                                      -6-

<PAGE>

          (d) The Seller hereby agrees that it shall be deemed to make, as of
the date of substitution, to and for the benefit of the Purchaser, with respect
to any replacement mortgage loan (a "Replacement Mortgage Loan") that is
substituted for a Defective Mortgage Loan (as defined in Section 5(a) hereof),
pursuant to Section 5(a) of this Agreement, each of the representations and
warranties set forth in Exhibit C hereto (references therein to "Closing Date"
being deemed to be references to the "date of substitution", references therein
to "Cut-off Date" being deemed to be references to the "most recent Due Date for
the subject Replacement Mortgage Loan on or before the date of substitution" and
references to "April 2003" and "March 2003" being deemed to be references to the
"month of substitution" and the "month preceding the month of substitution",
respectively). From and after the date of substitution, each Replacement
Mortgage Loan, if any, shall be deemed to constitute a "Mortgage Loan" hereunder
for all purposes (and, regardless of whether it replaced an Exhibit A-1 Loan or
an Exhibit A-2 Loan, shall also be deemed to constitute a "Exhibit A-1 Loan"
hereunder for all purposes).

          (e) It is understood and agreed that the representations and
warranties set forth in this Section 4 shall survive delivery of the respective
Mortgage Files for the Mortgage Loans to the Purchaser or its designee and shall
inure to the benefit of the Purchaser for so long as any of the Mortgage Loans
remains outstanding, notwithstanding any restrictive or qualified endorsement or
assignment.

          (f) For purposes of this Agreement, "Breach" shall mean a breach of
representation and warranty made by the Seller with respect to any Mortgage Loan
pursuant to Section 4(b) or 4(d) of this Agreement. Also for purposes of this
Agreement, "Material Breach" shall mean, with respect to any Mortgage Loan or
REO Property, any Breach that materially and adversely affects the value of, or
the interests of the Purchaser (or, for so long as such Mortgage Loan is subject
to the Pooling and Servicing Agreement, of the Trust) in, such Mortgage Loan or
REO Property, or that materially and adversely affects any Certificateholder.

          SECTION 5. Notice of Breach; Cure, Repurchase and Substitution.

          (a) The Purchaser or one of its servicing agents shall provide the
Seller with written notice of any Material Breach or Material Document Defect
with respect to any Mortgage Loan. Within 90 days (or in the case of a Material
Document Defect that consists of the failure to deliver a Specially Designated
Mortgage Loan Document with respect to any Mortgage Loan, 15 days) of the
earlier of discovery or receipt of written notice by the Seller that there has
been a Material Breach or a Material Document Defect with respect to any
Mortgage Loan (such 90-day (or, if applicable, 15-day) period, the "Initial
Resolution Period"), the Seller shall, subject to the next paragraph and,
further, to Section 5(b) and Section 5(c) below, (i) correct or cure such
Material Breach or Material Document Defect, as the case may be, in all material
respects or (ii) repurchase the Mortgage Loan affected by such Material Breach
or such Material Document Defect (such Mortgage Loan, a "Defective Mortgage
Loan"), as the case may be, at the related Purchase Price, with payment to be
made in accordance with the reasonable directions of the Purchaser; provided
that if the Seller shall have delivered to the Purchaser a certification
executed on behalf of the Seller by an officer thereof stating (i) that such
Material Breach or Material Document Defect, as the case may be, does not relate
to whether the Defective Mortgage Loan is or, as of the Closing Date (or, in the
case of a

                                      -7-

<PAGE>

Replacement Mortgage Loan, as of the related date of substitution), was a
"qualified mortgage" within the meaning of Section 860G(a)(3) of the Code (a
"Qualified Mortgage"), (ii) that such Material Breach or Material Document
Defect, as the case may be, is capable of being cured but not within the
applicable Initial Resolution Period, (iii) that the Seller has commenced and is
diligently proceeding with the cure of such Material Breach or Material Document
Defect, as the case may be, within the applicable Initial Resolution Period,
(iv) what actions the Seller is pursuing in connection with the cure thereof and
(v) that the Seller anticipates that such Material Breach or Material Document
Defect, as the case may be, will be cured within an additional period not to
exceed the applicable Resolution Extension Period (as defined below), then the
Seller shall have an additional period equal to the applicable Resolution
Extension Period to complete such cure or, failing such, to repurchase the
Defective Mortgage Loan; and provided, further, that, if the Seller's obligation
to repurchase any Defective Mortgage Loan as a result of a Material Breach or
Material Document Defect, as applicable, arises within the three-month period
commencing on the Closing Date (or within the two-year period commencing on the
Closing Date if the Defective Mortgage Loan is a "defective obligation" within
the meaning of Section 860G(a)(4)(B)(ii) of the Code and Treasury regulation
section 1.860G-2(f)), and if the Defective Mortgage Loan is still subject to the
Pooling and Servicing Agreement, then the Seller may, at its option, subject to
the terms, conditions and limitations set forth in the Pooling and Servicing
Agreement, in lieu of repurchasing such Defective Mortgage Loan (but, in any
event, no later than such repurchase would have to have been completed), (i)
replace such Defective Mortgage Loan with one or more substitute mortgage loans
that individually and collectively satisfy the requirements of the definition of
"Qualifying Substitute Mortgage Loan" set forth in the Pooling and Servicing
Agreement, and (ii) pay any corresponding Substitution Shortfall Amount, such
substitution and payment to be effected in accordance with the terms of the
Pooling and Servicing Agreement. Any such repurchase or replacement of a
Defective Mortgage Loan shall be on a whole loan, servicing released basis. The
Seller shall have no obligation to monitor the Mortgage Loans regarding the
existence of a Material Breach or Material Document Defect, but if the Seller
discovers a Material Breach or a Material Document Defect with respect to any
Mortgage Loan, it will notify the Purchaser.

                                      -8-

<PAGE>

          Notwithstanding the foregoing, if there exists a Breach of any
representation or warranty on the part of a the Seller set forth in, or made
pursuant to, Section 4(b) or 4(d) of this Agreement relating to whether or not
the Mortgage Loan Documents or any particular Mortgage Loan Document for any
Mortgage Loan for any reason requires the related Borrower to bear the costs and
expenses associated with any particular action or matter under such Mortgage
Loan Document(s), then the Seller shall, in accordance with, and no later than
90 days following the Seller's receipt of, the written directions of the
Purchaser or its servicing agent, wire transfer to the account designated in
those directions, the amount of any such costs and expenses borne by the
Purchaser that are the basis of such Breach. Upon its making such wire transfer,
the Seller shall be deemed to have cured such Breach in all respects. Provided
that such payment is made, this paragraph describes the sole remedy available to
the Purchaser (including, without limitation, the Certificateholders and the
Trustee on their behalf) regarding any such Breach, regardless of whether it
constitutes a Material Breach, and the Seller shall not be obligated to
otherwise cure such Breach or repurchase the affected Mortgage Loan under any
circumstances.

          "Resolution Extension Period" shall mean:

          (i) for purposes of remediating a Material Breach with respect to any
     Mortgage Loan, 90 days;

          (ii) for purposes of remediating a Material Document Defect with
     respect to any Mortgage Loan that is and remains a Performing Pooled
     Mortgage Loan throughout the applicable Initial Resolution Period, the
     period commencing at the end of the applicable Initial Resolution Period
     and ending on, and including, the earlier of (A) the 90th day following the
     end of such Initial Resolution Period and (B) the 45th day following the
     Seller's receipt of written notice from the Purchaser or its servicing
     agent of the occurrence of any Servicing Transfer Event with respect to
     such Mortgage Loan subsequent to the end of such Initial Resolution Period;

          (iii) for purposes of remediating a Material Document Defect with
     respect to any Mortgage Loan that is a Performing Pooled Mortgage Loan as
     of the commencement of the applicable Initial Resolution Period, but as to
     which a Servicing Transfer Event occurs during such Initial Resolution
     Period, the period commencing at the end of the applicable Initial
     Resolution Period and ending on, and including, the 90th day following the
     earlier of (A) the end of such Initial Resolution Period and (B) the
     Seller's receipt of written notice from the Purchaser or its servicing
     agent of the occurrence of such Servicing Transfer Event; and

          (iv) for purposes of remediating a Material Document Defect with
     respect to any Mortgage Loan that is a Specially Serviced Pooled Mortgage
     Loan or has become a Pooled REO Loan as of the commencement of the
     applicable Initial Resolution Period, the 30th day following the end of
     such Initial Resolution Period; provided that, if the Seller did not
     receive written notice from the Purchaser or its servicing agent of the
     relevant Servicing Transfer Event as of the commencement of the applicable
     Initial Resolution Period, then such Servicing Transfer Event will be
     deemed to have occurred

                                      -9-

<PAGE>

     during such Initial Resolution Period and clause (iii) of this definition
     will be deemed to apply;

provided that, except as otherwise set forth in the following two provisos,
there shall be no Resolution Extension Period in respect of a Material Document
Defect involving a Specially Designated Mortgage Loan Document; and provided,
further, that if a Material Document Defect exists with respect to any Mortgage
Loan, if such Mortgage Loan is then subject to the Pooling and Servicing
Agreement, and if the Seller escrows with the Master Servicer, prior to the end
of the Initial Resolution Period and any Resolution Extension Period otherwise
applicable to the remediation of such Material Document Defect without regard to
this proviso, cash in the amount of the then Purchase Price for such Mortgage
Loan and subsequently delivers to the Master Servicer, on a monthly basis, such
additional cash as may be necessary to maintain a total escrow equal to the
Purchase Price for such Mortgage Loan as such price may increase over time (the
total amount of cash delivered to the Master Servicer with respect to any
Mortgage Loan as contemplated by this proviso or the immediately following
proviso, the "Purchase Price Security Deposit"), then the Resolution Extension
Period applicable to the remediation of such Material Document Defect shall be
extended until the earliest of (i) the second anniversary of the Closing Date,
(ii) the date on which such Mortgage Loan is no longer outstanding and part of
the Trust Fund and (iii) if such Mortgage Loan becomes a Specially Serviced
Pooled Mortgage Loan under the Pooling and Servicing Agreement, the date, if
any, on which the Special Servicer determines in its reasonable, good faith
judgment that such Material Document Defect will materially interfere with or
delay the realization against the related Mortgaged Property or materially
increase the cost thereof; and provided, further, that if the Material Document
Defect referred to in the preceding proviso consists of a failure to deliver a
Specially Designated Mortgage Loan Document, and if the Seller delivers to the
Master Servicer a Purchase Price Security Deposit equal to 25% of the
outstanding principal balance of the subject Mortgage Loan, then the Resolution
Extension Period applicable to the remediation of such Material Document Defect
shall be extended to the 15th day following the end of the applicable Initial
Resolution Period.

          The Purchaser or its servicing agent shall establish, and maintain any
Purchase Price Security Deposit delivered to it with respect to any Mortgage
Loan in, one or more accounts (individually and collectively, the "Purchase
Price Security Deposit Account") and shall be entitled to make withdrawals from
such account(s) for the following purposes: (i) to cover any costs and expenses
resulting from the applicable Material Document Defect; (ii) upon any discounted
payoff or other liquidation of such Mortgage Loan, to cover any Realized Loss
related thereto; and (iii) if the Seller so directs, or if the balance on
deposit in the Purchase Price Security Deposit Account declines, and for 45 days
remains, below the Purchase Price for such Mortgage Loan (except where a
Purchase Price Security Deposit equal to 25% of the outstanding principal
balance of the subject Mortgage Loan is permitted to be delivered in order to
obtain a 15-day Resolution Extension Period with respect to the failure to
deliver a Specially Designated Mortgage Loan Document), or if such Material
Document is not remedied on or before the second anniversary of the Closing
Date, or if such Mortgage Loan becomes a Specially Serviced Pooled Mortgage Loan
under the Pooling and Servicing Agreement and the Special Servicer determines in
its reasonable, good faith judgment that such Material Document Defect will
materially interfere with or delay the realization against the related Mortgaged
Property or

                                      -10-

<PAGE>

materially increase the cost thereof, to apply the Purchase Price Security
Deposit to a full or partial, as applicable, payment of the Purchase Price for
such Mortgage Loan (with the Seller to pay any remaining balance of such
Purchase Price). The Seller may obtain a release of the Purchase Price Security
Deposit for any Mortgage Loan (net of any amounts payable therefrom as
contemplated by the prior sentence) upon such Mortgage Loan's being paid in full
or otherwise satisfied, liquidated or removed from the Trust Fund or upon the
subject Material Document Defect's being remedied in all material respects and
all associated fees and expenses being paid in full. The Seller may direct the
Purchaser or its servicing agent to invest or cause the investment of the funds
deposited in any Purchase Price Security Deposit Account in one or more
Permitted Investments that bear interest or are sold at a discount and that
mature, unless payable on demand, no later than the Business Day prior to the
next Master Servicer Remittance Date. The Purchaser or its servicing agent shall
act upon the written instructions of the Seller with respect to the investment
of funds in any Purchase Price Security Deposit Account in such Permitted
Investments; provided that in the absence of appropriate written instructions
from the Seller, the Purchaser shall have no obligation to invest or direct the
investment of funds in such Purchase Price Security Deposit Account. All income
and gain realized from the investment of funds deposited in any Purchase Price
Security Deposit Account shall be for the benefit of the Seller and shall be
withdrawn by the Purchaser or its servicing agent and remitted to the Seller on
each Master Servicer Remittance Date (net of any losses incurred and any
deposits required to be made by the Seller as contemplated by the second proviso
to the prior paragraph), and the Seller shall remit to the Purchaser from the
Seller's own funds for deposit into such Purchase Price Security Deposit Account
the amount of any realized losses (net of realized gains) in respect of such
Permitted Investments immediately upon realization of such net losses and
receipt of written notice thereof from the Purchaser; provided that the Seller
shall not be required to make any such deposit for any realized loss which is
incurred solely as a result of the insolvency of the federal or state depository
institution or trust company that holds such Purchase Price Security Deposit
Account. Neither the Purchaser nor any of its servicing agents shall have any
responsibility or liability with respect to the investment directions of the
Seller, the investment of funds in any Purchase Price Security Deposit Account
in Permitted Investments or any losses resulting therefrom.

          If one or more (but not all) of the Mortgage Loans constituting a
Cross-Collateralized Group are to be repurchased or replaced by the Seller as
contemplated by this Section 5(a), then, prior to the subject repurchase or
substitution, the Purchaser or its servicing agent shall use its best efforts,
subject to the terms of such 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 (as to each such group, the "Primary
Real Property Collateral"); provided that, if the affected Cross-Collateralized
Group is then subject to the Pooling and Servicing Agreement, then no such
termination shall be affected unless and until the Trustee and the Master
Servicer shall have received from the Seller (i) an Opinion of Counsel from
independent counsel to the effect that such termination will not cause an
Adverse REMIC Event to occur with respect to any REMIC Pool or an Adverse
Grantor Trust

                                      -11-

<PAGE>

Event with respect to either Grantor Trust Pool 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 the Seller may, at its option, purchase the entire subject
Cross-Collateralized Group in lieu of terminating the cross-collateralization.
All costs and expenses incurred by the Purchaser and its servicing agents
pursuant to this paragraph (to the extent not reimbursed by the related
Borrower) shall be included in the calculation of Purchase Price for the
Mortgage Loan(s) to be repurchased or replaced.

          If the cross-collateralization of any Cross-Collateralized Group of
Mortgage Loans cannot be terminated as contemplated by the prior paragraph for
any reason (including, but not limited to, the Seller's failure to satisfy any
of the conditions set forth in the first proviso to the first sentence of the
prior paragraph), if the Seller has not elected to purchase the entire affected
Cross-Collateralized Group, and if such Cross-Collateralized Group is then
subject to the Pooling and Servicing Agreement, then, to the extent that the
Seller is required to repurchase or replace any Mortgage Loan in that
Cross-Collateralized Group in the manner prescribed above while the Trust
continues to hold any other Mortgage Loan in that Cross-Collateralized Group,
the Trustee, on behalf of the Trust, and the Seller each hereby agrees to
forbear from enforcing any remedies against the other's Primary Real Property
Collateral but may exercise remedies against the Primary Real Property
Collateral securing the Mortgage Loans in that Cross-Collateralized Group held
by it; provided that the Trustee and the Master Servicer shall have received, at
the expense of the Seller, an Opinion of Counsel from independent counsel to the
effect that (i) the exercise of remedies by the Seller, on the one hand, or the
Trust, on the other hand, with respect to the Primary Real Property Collateral
securing the respective Mortgage Loan(s) in such Cross-Collateralized Group held
by such party would not materially and adversely affect the rights of the other
such party to proceed against the Primary Real Property Collateral for the
respective Mortgage Loan(s) in such Cross-Collateralized Group held by such
other party and (ii) the foregoing arrangement would not result in an Adverse
REMIC Event with respect to any REMIC Pool or an Adverse Grantor Trust Event
with respect to any Grantor Trust Pool. Any reserve or other cash collateral or
letters of credit securing the subject Cross-Collateralized Group shall be
allocated between the Mortgage Loans therein held by the Seller, on the one
hand, and the Trust, on the other hand, in accordance with the related Mortgage
Loan documents, or otherwise on a pro rata basis based upon the outstanding
principal balances of their respective Mortgage Loans in such
Cross-Collateralized Group. All other terms of the Mortgage Loans in such
Cross-Collateralized Group shall remain in full force and effect, without any
modification thereof. The Borrowers under the respective Cross-Collateralized
Groups of Mortgage Loans are intended third-party beneficiaries of the provision
set forth in this paragraph. The provisions of this paragraph may not be
modified with respect to any Mortgage Loan in a Cross-Collateralized Group
without the related Borrower's consent.

          If the cross-collateralization of any Cross-Collateralized Group of
Mortgage Loans cannot be terminated as contemplated by the second preceding
paragraph for any reason (including, but not limited to, the Seller's failure to
satisfy any of the conditions set forth in the first proviso to the first
sentence of the second preceding paragraph) and the forbearance arrangement in
respect of such Cross-Collateralized Group cannot be effected as contemplated by
the preceding paragraph for any reason (including, but not limited to, the
Seller's failure to satisfy any of the conditions set forth in the proviso to
the first sentence of the prior paragraph)

                                      -12-

<PAGE>

then the entire Cross-Collateralized Group shall be repurchased or replaced if
the subject Material Breach or Material Document Defect, as the case may be, is
not remedied in all material respects by the end of the applicable Initial
Resolution Period and any applicable Resolution Extension Period.

          Whenever one or more mortgage loans are substituted by the Seller for
a Defective Mortgage Loan as contemplated by this Section 5(a), the Seller shall
(i) deliver the related Mortgage File for each such substitute mortgage loan to
the Purchaser or its designee (which designee, unless otherwise stated, is the
Trustee), (ii) certify that such substitute mortgage loan satisfies or such
substitute mortgage loans satisfy, as the case may be, all of the requirements
of the definition of "Qualifying Substitute Mortgage Loan" set forth in the
Pooling and Servicing Agreement and (iii) send such certification to the
Purchaser or its designee. No mortgage loan may be substituted for a Defective
Mortgage Loan as contemplated by this Section 5(a) if the Defective Mortgage
Loan to be replaced was itself a Replacement Mortgage Loan, in which case,
absent cure of the relevant Material Breach or Material Document Defect, the
Defective 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 Defective Mortgage Loan (if any) after the Cut-off Date (or, in
the case of a Replacement Mortgage Loan, after the date on which it is added to
the Trust Fund) and on or prior to the related date of repurchase or
replacement, shall belong to the Purchaser. 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 Defective Mortgage
Loan (if any) after the related date of repurchase or replacement, shall belong
to the Seller.

          If any Defective Mortgage Loan is to be repurchased or replaced as
contemplated by this Section 5(a), the Seller shall amend the Mortgage Loan
Schedule to reflect the removal of the Defective Mortgage Loan and, if
applicable, the substitution of the related Replacement Mortgage Loan(s) and
shall forward such amended schedule to the Purchaser.

          (b) It shall be a condition to any repurchase or replacement of a
Defective Mortgage Loan by the Seller pursuant to Section 5(a) that the
Purchaser (which shall include the Trustee) shall have executed and delivered
such instruments of transfer or assignment then presented to it by the Seller,
in each case without recourse, as shall be necessary to vest in the Seller the
legal and beneficial ownership of such Defective Mortgage Loan (including any
property acquired in respect thereof or proceeds of any insurance policy with
respect thereto), to the extent that such ownership interest was transferred to
the Purchaser hereunder.

          (c) If, on or after October 11, 2004, the Seller receives notice of a
Material Document Defect with respect to any Mortgage Loan, which Material
Document Defect constitutes a Recording Omission, and if such Mortgage Loan is
still subject to the Pooling and Servicing Agreement, then the Seller, with the
consent of the Controlling Class Representative, which consent may be granted or
withheld in its sole discretion, in lieu of repurchasing or replacing such
Mortgage Loan (as and to the extent contemplated by Section 5(a) above), but in
no event later than such repurchase would have to have been completed, establish
a Recording Omission Credit or a Recording Omission Reserve with the Master
Servicer. In furtherance of

                                      -13-

<PAGE>

the preceding sentence, the Purchaser or its servicing agent shall establish one
or more accounts (individually and collectively, the "Special Reserve Account"),
each of which shall be an Eligible Account, and the Purchaser or its servicing
agent shall deposit any Recording Omission Reserve into the Special Reserve
Account within one Business Day of receipt. The Seller may direct the Purchaser
or its servicing agent to invest or cause the investment of the funds deposited
in the Special Reserve Account in one or more Permitted Investments that bear
interest or are sold at a discount and that mature, unless payable on demand, no
later than the Business Day prior to the next Master Servicer Remittance Date.
The Purchaser or its servicing agent shall act upon the written instructions of
the Seller with respect to the investment of funds in the Special Reserve
Account in such Permitted Investments, provided that in the absence of
appropriate written instructions from the Seller, the Purchaser shall have no
obligation to invest or direct the investment of funds in such Special Reserve
Account. All income and gain realized from the investment of funds deposited in
such Special Reserve Account shall be for the benefit of the Seller and shall be
withdrawn by the Purchaser or its servicing agent and remitted to the Seller on
each Master Servicer Remittance Date (net of any losses incurred), and the
Seller shall remit to the Purchaser from the Seller's own funds for deposit into
such Special Reserve Account the amount of any realized losses (net of realized
gains) in respect of such Permitted Investments immediately upon realization of
such net losses and receipt of written notice thereof from the Purchaser;
provided that the Seller shall not be required to make any such deposit for any
realized loss which is incurred solely as a result of the insolvency of the
federal or state depository institution or trust company that holds such Special
Reserve Account. Neither the Purchaser nor any of its servicing agents shall
have any responsibility or liability with respect to the investment directions
of the Seller, the investment of funds in the Special Reserve Account in
Permitted Investments or any losses resulting therefrom. A Recording Omission
Credit shall (i) entitle the Purchaser or its servicing agent to draw upon the
Recording Omission Credit on behalf of the Purchaser upon presentation of only a
sight draft or other written demand for payment, (ii) permit multiple draws by
the Purchaser or its servicing agent, and (iii) be issued by such issuer and
containing such other terms as the Purchaser or its servicing agent may
reasonably require to make such Recording Omission Credit reasonably equivalent
security to a Recording Omission Reserve in the same amount. Once a Recording
Omission Reserve or Recording Omission Credit is established with respect to any
Mortgage Loan, the Purchaser or its servicing agent shall, from time to time,
withdraw funds from the related Special Reserve Account or draw upon the related
Recording Omission Credit, as the case may be, and apply the proceeds thereof to
pay the losses or expenses directly incurred by the Purchaser or its servicing
agent as a result of a Recording Omission. The Recording Omission Reserve or
Recording Omission Credit or any unused balance thereof with respect to any
Mortgage Loan will be released to the Seller by the Purchaser upon the earlier
of the Seller's cure of all Recording Omissions with respect to such Mortgage
Loan (provided that the Purchaser has been reimbursed with respect to all losses
and expenses relating to Recording Omissions with respect to such Mortgage Loan)
and such Mortgage Loan's no longer being a part of the Trust Fund under the
Pooling and Servicing Agreement.

          (d) It is understood and agreed that the obligations of the Seller set
forth in this Section 5 to cure a Material Breach or a Material Document Defect
with respect to any Mortgage Loan, repurchase or replace the related Defective
Mortgage Loan(s) or establish a Recording Omission Credit or a Recording
Omission Reserve with respect to the related

                                      -14-

<PAGE>

Defective Mortgage Loan(s), constitute the sole remedies available to the
Purchaser, the Certificateholders or the Trustee on behalf of the
Certificateholders with respect to a Breach or a Document Defect in respect of
any Mortgage Loan.

          (e) If the Seller disputes that a Material Document Defect or a
Material Breach exists with respect to a Mortgage Loan or otherwise refuses (i)
to effect a correction or cure of such Material Document Defect or Material
Breach, (ii) to repurchase the related Defective Mortgage Loan from the
Purchaser or its assignee or (iii) to replace the related Defective Mortgage
Loan with a Qualifying Substitute Mortgage Loan, each in accordance with the
foregoing provisions of this Section 5, then (provided that (i) the Defective
Mortgage Loan is then subject to the Pooling and Servicing Agreement, (ii) the
applicable Initial Resolution Period and any applicable Resolution Extension
Period has expired and (iii) the Defective Mortgage Loan is then in default and
is then a Specially Serviced Pooled Mortgage Loan) the Special Servicer may,
subject to the Servicing Standard, modify, work-out or foreclose, sell or
otherwise liquidate (or permit the liquidation of) the Defective Mortgage Loan
pursuant to the terms of the Pooling and Servicing Agreement, while pursuing the
repurchase claim, and such action shall not be a defense to the repurchase claim
or alter the applicable Purchase Price.

          If any REO Property in respect of any Defective Mortgage Loan is
subject to the Pooling and Servicing Agreement, then the Seller shall be
notified promptly and in writing by the Special Servicer of any offer that it
receives to purchase such REO Property. Upon the receipt of such notice by the
Seller, the Seller shall then have the right to repurchase such REO Property
from the Trust at a purchase price equal to the amount of such offer. The Seller
shall have three (3) Business Days to purchase such REO Property from the date
that it was notified of such offer. The Special Servicer shall be obligated to
provide the Seller with any appraisal or other third-party reports relating to
such REO Property within its possession to enable the Seller to evaluate such
REO Property. Any sale of a Mortgage Loan, or foreclosure upon such Mortgage
Loan and sale of any related REO Property, to a Person other than the Seller
shall be (i) without recourse of any kind (either expressed or implied) by such
Person against the Seller and (ii) without representation or warranty of any
kind (either expressed or implied) by the Seller to or for the benefit of such
Person.

          The fact that a Material Document Defect or Material Breach is not
discovered until after foreclosure (but in all instances prior to the sale of
the subject Defective Mortgage Loan or REO Property) shall not prejudice any
claim of the Trust against the Seller for repurchase of the subject Defective
Mortgage Loan or REO Property. The provisions of this Section 5 regarding
remedies against the Seller for a Material Breach or Material Document Defect
with respect to any Mortgage Loan shall also apply to the related REO Property.

          If the Seller fails to correct or cure the Material Document Defect or
Material Breach or purchase the subject REO Property, then the provisions above
regarding notice of offers related to such REO Property and the Seller's right
to purchase such REO Property shall apply. If a court of competent jurisdiction
issues a final order that the Seller is or was obligated to repurchase the
related Defective Mortgage Loan or REO Property or the Seller otherwise accepts
liability, then, after the expiration of any applicable appeal period, but in no
event later than the termination of the Trust pursuant to the Pooling and
Servicing Agreement, the Seller

                                      -15-

<PAGE>

will be obligated to pay to the Trust the amount, if any, by which the
applicable Purchase Price exceeds any Liquidation Proceeds received upon such
liquidation (including those arising from any sale to the Seller); provided that
the prevailing party in such action shall be entitled to recover all costs, fees
and expenses (including reasonable attorneys' fees) related thereto.

          (f) If the Purchaser or its servicer notifies the Seller that the
borrower under the Mortgage Loan that is secured by the Mortgaged Property
identified on Exhibit A-1 hereto as Sully Place (such Mortgage Loan, the "Sully
Place Mortgage Loan") intends to defease such Mortgage Loan prior to the second
anniversary of the date of initial issuance of the Certificates, the Seller
shall promptly repurchase the Sully Place Mortgage Loan prior to its being
defeased by the subject borrower, with such repurchase to be made at the related
Purchase Price on a whole loan, servicing released basis, in accordance with the
directions of the Master Servicer. Upon the repurchase of the Sully Place
Mortgage Loan pursuant to this Section 5(f), the Purchaser shall effect, and the
Seller shall pay all reasonable costs and expenses, including the costs of any
opinions of counsel under the Pooling and Servicing Agreement, relating to, a
"qualified liquidation" of the related Loan REMIC in accordance with the REMIC
Provisions. In connection with any such repurchase of the Sully Place Mortgage
Loan and the payment of the Sully Place Yield Maintenance Amount by the Seller,
(i) the Purchaser (which shall include the Trustee) shall execute and deliver
such instruments of transfer or assignment then presented to it by the Seller,
in each case without recourse, as shall be necessary to vest in the Seller the
legal and beneficial ownership of the Sully Place Mortgage Loan (including any
property acquired in respect thereof or proceeds of any insurance policy with
respect thereto), to the extent that such ownership interest was transferred to
the Purchaser hereunder; and (ii) the Seller shall amend the Mortgage Loan
Schedule to reflect the removal of the Sully Place Mortgage Loan.

          SECTION 6. Closing. The closing of the sale of the Mortgage Loans (the
"Closing") shall be held at the offices of Sidley Austin Brown & Wood LLP, 787
Seventh Avenue, New York, New York 10019 at 10:00 a.m., New York City time, on
the Closing Date.

          The Closing shall be subject to each of the following conditions:

          (i) all of the representations and warranties of the Seller made
     pursuant to Section 4 of this Agreement shall be true and correct in all
     material respects as of the Closing Date;

          (ii) all documents specified in Section 7 of this Agreement (the
     "Closing Documents"), in such forms as are agreed upon and reasonably
     acceptable to the Purchaser and, in the case of the Pooling and Servicing
     Agreement (insofar as such Agreement affects the obligations of the Seller
     hereunder), to the Seller, shall be duly executed and delivered by all
     signatories as required pursuant to the respective terms thereof;

          (iii) the Seller shall have delivered and released to the Purchaser or
     its designee, all documents, funds and other assets required to be
     delivered thereto pursuant to Section 2 of this Agreement;

                                      -16-

<PAGE>

          (iv) the result of any examination of the Mortgage Files for, and any
     other documents and records relating to, the Mortgage Loans performed by or
     on behalf of the Purchaser pursuant to Section 3 hereof shall be
     satisfactory to the Purchaser in its reasonable determination;

          (v) all other terms and conditions of this Agreement required to be
     complied with on or before the Closing Date shall have been complied with
     in all material respects, and the Seller shall have the ability to comply
     with all terms and conditions and perform all duties and obligations
     required to be complied with or performed after the Closing Date;

          (vi) the Seller shall have received the consideration for the Mortgage
     Loans, as contemplated by Section 1;

          (vii) the Seller shall have paid all fees and expenses payable by it
     to the Purchaser or otherwise pursuant to this Agreement; and

          (viii) neither the Underwriting Agreement nor the Certificate Purchase
     Agreement shall have been terminated in accordance with its terms.

          Both parties agree to use their commercially reasonable best efforts
to perform their respective obligations hereunder in a manner that will enable
the Purchaser to purchase the Mortgage Loans on the Closing Date.

          SECTION 7. Closing Documents. The Closing Documents shall consist of
the following:

          (i) this Agreement, duly executed by the Purchaser and the Seller;

          (ii) each of the Pooling and Servicing Agreement and the

          (ix) a letter from Sidley Austin Brown & Wood LLP, special counsel for

          SECTION 8. Costs. Whether or not this Agreement is terminated, the
costs and expenses incurred in connection with the transactions herein
contemplated shall be allocated pursuant to the terms of the settlement
agreement dated the Closing Date.

          SECTION 9. Notices. All demands, notices and communications hereunder
shall be in writing and shall be deemed to have been duly given if personally
delivered to or mailed, by registered mail, postage prepaid, by overnight mail
or courier service, or transmitted by facsimile and confirmed by similar mailed
writing, if to the Purchaser, addressed to the Purchaser at 11 Madison Avenue,
5th Floor, New York, New York 10010, Attention: Edmund Taylor, Telecopy No.:
(212) 743-4756 (with a copy to Pamela McCormack, Telecopy No.: (917) 326-7805),
or such other address as may be designated by the Purchaser to the Seller in
writing, or, if to the Seller, addressed to the Seller at 3414 Peachtree Road,
N.E., Suite 1140, Atlanta, Georgia 30326, Attention: Robert Barnes, Telecopy
No.: (404) 261-5879, or such other address as may be designated by the Seller to
the Purchaser in writing.

          SECTION 10. Miscellaneous. Neither this Agreement nor any term or
provision hereof may be changed, waived, discharged or terminated except by a
writing signed by a duly authorized officer of the party against whom
enforcement of such change, waiver, discharge or termination is sought to be
enforced. This Agreement may be executed in any number of counterparts, each of
which shall for all purposes be deemed to be an original and all of which shall
together constitute but one and the same instrument. This Agreement will inure
to the benefit of and be binding upon the parties hereto and their respective
successors and assigns, and no other person will have any right or obligation
hereunder. Notwithstanding any contrary provision of this Agreement or the
Pooling and Servicing Agreement, the Purchaser shall not consent to any
amendment of the Pooling and Servicing Agreement which will increase the
obligations of, or otherwise adversely affect, the Seller, without the consent
of the Seller.

          SECTION 11. Characterization. The parties hereto agree that it is
their express intent that the conveyance contemplated by this Agreement be, and
be treated for all purposes as, a sale by the Seller of all the Seller's right,
title and interest in and to the Mortgage Loans. The parties hereto further
agree that it is not their intention that such conveyance be a pledge of the
Mortgage Loans by the Seller to secure a debt or other obligation of the Seller.
However, in the event that, notwithstanding the intent of the parties, the
Mortgage Loans are held to continue to be property of the Seller, then: (a) this
Agreement shall be deemed to be a security agreement under applicable law; (b)
the transfer of the Mortgage Loans provided for herein shall be deemed to be a
grant by the Seller to the Purchaser of a first priority security interest in
all of the Seller's right, title and interest in and to the Mortgage Loans and
all amounts payable to the holder(s) of the Mortgage Loans in accordance with
the terms thereof (other than scheduled payments of interest and principal due
on or before the Cut-off Date) and all proceeds of the conversion, voluntary or
involuntary, of the foregoing into cash, instruments, securities or other
property; (c) the assignment by CSFB Mortgage Securities to the Trustee of its
interests in the Mortgage Loans as contemplated by Section 16 hereof shall be
deemed to be an assignment of any security interest created hereunder; (d) the
possession by the Purchaser of the related Mortgage Notes 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" for purposes of
perfecting the security interest under applicable law; and (e) notifications to,
and acknowledgments, receipts or

                                      -19-

<PAGE>

confirmations from, persons or entities holding such property, shall be deemed
notifications to, or acknowledgments, receipts or confirmations from, securities
intermediaries, bailees or agents (as applicable) of the Purchaser for the
purpose of perfecting such security interest under applicable law. The Seller
and the Purchaser shall, to the extent consistent with this Agreement, take such
actions, including, without limitation, the filing of UCC financing statements,
as may be necessary to ensure that, if this Agreement were deemed to create a
security interest in the Mortgage Loans, such security interest would be a
perfected security interest of first priority under applicable law and will be
maintained as such throughout the term of this Agreement and the Pooling and
Servicing Agreement.

          SECTION 12. Representations, Warranties and Agreements to Survive
Delivery. All representations, warranties and agreements contained in this
Agreement, incorporated herein by reference or contained in the certificates of
officers of the Seller delivered pursuant hereto, shall remain operative and in
full force and effect and shall survive delivery of the Mortgage Loans by the
Seller to the Purchaser, notwithstanding any restrictive or qualified
endorsement or assignment in respect of any Mortgage Loan.

          SECTION 13. Severability of Provisions. Any part, provision,
representation, warranty or covenant of this Agreement that is prohibited or is
held to be void or unenforceable shall be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
hereof. Any part, provision, representation, warranty or covenant of this
Agreement that is prohibited or is held to be void or unenforceable in any
particular jurisdiction shall, as to such jurisdiction, be ineffective to the
extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
particular jurisdiction shall not invalidate or render unenforceable such
provision in any other jurisdiction. To the extent permitted by applicable law,
the parties hereto waive any provision of law which prohibits or renders void or
unenforceable any provision hereof.

          SECTION 14. GOVERNING LAW; CONSENT TO JURISDICTION. THIS AGREEMENT
WILL BE GOVERNED BY AND 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. TO THE FULLEST EXTENT PERMITTED UNDER APPLICABLE LAW, THE SELLER
AND THE PURCHASER EACH HEREBY IRREVOCABLY (I) SUBMITS TO THE JURISDICTION OF ANY
NEW YORK STATE AND FEDERAL COURTS SITTING IN NEW YORK CITY WITH RESPECT TO
MATTERS ARISING OUT OF OR RELATING TO THIS AGREEMENT; (II) AGREES THAT ALL
CLAIMS WITH RESPECT TO SUCH ACTION OR PROCEEDING SHALL BE HEARD AND DETERMINED
IN SUCH NEW YORK STATE OR FEDERAL COURTS; (III) WAIVES, TO THE FULLEST POSSIBLE
EXTENT, THE DEFENSE OF AN INCONVENIENT FORUM; AND (IV) AGREES THAT A FINAL
JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE
ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER
PROVIDED BY LAW.

          SECTION 15. Further Assurances. The Seller and the Purchaser agree to
execute and deliver such instruments and take such further actions as the other
party may, from time to time, reasonably request in order to effectuate the
purposes and to carry out the terms of this Agreement.

          SECTION 16. Successors and Assigns. The rights and obligations of the
Seller under this Agreement shall not be assigned by the Seller without the
prior written consent of the Purchaser, except that any person into which the
Seller may be merged or consolidated, or any corporation or other legal entity
resulting from any merger, conversion or consolidation to which the Seller is a
party, or any person succeeding to all or substantially all of the business of
the Seller, shall be the successor to the Seller hereunder. In connection with
its transfer of the Mortgage Loans to the Trust as contemplated by the recitals
hereto, CSFB Mortgage Securities is expressly authorized to assign its rights
and obligations under this Agreement, in whole or in part, to the Trustee for
the benefit of the registered holders and beneficial owners of the Certificates.
To the extent of any such assignment, the Trustee, for the benefit of the
registered holders and beneficial owners of the Certificates, shall be the
Purchaser hereunder. In connection with the transfer of any Mortgage Loan by the
Trust as contemplated by the terms of the Pooling and Servicing Agreement, the
Trustee, for the benefit of the registered holders and beneficial owners of the
Certificates, is expressly authorized to assign its rights and obligations under
this Agreement, in whole or in part, to the transferee of such Mortgage Loan. To
the extent of any such assignment, such transferee shall be the Purchaser
hereunder (but solely with respect to such Mortgage Loan that was transferred to
it). Subject to the foregoing, this Agreement shall bind and inure to the
benefit of and be enforceable by the Seller and the Purchaser, and their
respective successors and permitted assigns.

          SECTION 17. Information. On or before the Closing Date, the Seller
shall provide the Purchaser with such information about the Seller, the Mortgage
Loans and the Seller's underwriting and servicing procedures as is (i) customary
in commercial mortgage loan securitization transactions, (ii) required by a
Rating Agency or a governmental agency or body or (iii) reasonably requested by
the Purchaser for use in a public or private disclosure document.

          SECTION 18. Cross-Collateralized Mortgage Loans. Notwithstanding
anything herein to the contrary, it is hereby acknowledged that certain groups
of Mortgage Loans are, in the case of each such particular group of Mortgage
Loans (each, a "Cross-Collateralized Group"), by their terms, cross-defaulted
and cross-collateralized. Each Cross-Collateralized Group is identified on the
Mortgage Loan Schedule. For purposes of reference, the Mortgaged Property that
relates or corresponds to any of the Mortgage Loans referred to in this Section
18 shall be the property identified in the Mortgage Loan Schedule as
corresponding thereto. The provisions of this Agreement, including, without
limitation, each of the representations and warranties set forth in Exhibit C
hereto and each of the capitalized terms used herein but defined in the Pooling
and Servicing Agreement, shall be interpreted in a manner consistent with this
Section 18. In addition, if there exists with respect to any
Cross-Collateralized Group only one original of any document referred to in the
definition of "Mortgage File" in the Pooling and Servicing Agreement and
covering all the Mortgage Loans in such Cross-Collateralized Group, the
inclusion of the original of such document in the Mortgage File for any of the
Mortgage

                                      -21-

<PAGE>

Loans constituting such Cross-Collateralized Group shall be deemed an inclusion
of such original in the Mortgage File for each such Mortgage Loan.

          SECTION 19. Entire Agreement. Except as otherwise expressly
contemplated hereby, this Agreement constitutes the entire agreement and
understanding of the parties with respect to the matters addressed herein, and
this Agreement supersedes any prior agreements and/or understandings, written or
oral, with respect to such matters.

                                   Exhibit B-1

            Representations and Warranties with Respect to the Seller

          The Seller hereby represents and warrants that, as of the Closing
Date:

          1. The Seller is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware.

          2. The execution and delivery by the Seller of, and the performance by
the Seller under, this Agreement, the execution (including, without limitation,
by facsimile or machine signature) and delivery of any and all documents
contemplated by this Agreement, including, without limitation, if necessary,
endorsements of Mortgage Notes, and the consummation by the Seller of the
transactions herein contemplated, will not: (a) violate the Seller's
organizational documents; or (b) constitute a default (or an event which, with
notice or lapse of time, or both, would constitute a default) under, or result
in the breach of, any indenture, agreement or other instrument to which the
Seller is a party or by which it is bound or which is applicable to it or any of
its assets, which default or breach, in the Seller's good faith and reasonable
judgment, is likely to affect materially and adversely either the ability of the
Seller to perform its obligations under this Agreement or the financial
condition of the Seller.

          3. The Seller has full power and authority to enter into and perform
under this Agreement, has duly authorized the execution, delivery and
performance of this Agreement, and has duly executed and delivered this
Agreement.

          4. The Seller has the full right, power and authority to sell, assign,
transfer, set over and convey all of its right, title and interest in and to the
Mortgage Loans (and, in the event that the related transaction is deemed to
constitute a loan secured by all or part of the Mortgage Loans, to pledge all of
its right, title and interest in and to such Mortgage Loans) in accordance with,
and under the conditions set forth in, this Agreement.

          5. Assuming due authorization, execution and delivery hereof by the
Purchaser, this Agreement constitutes a valid, legal and binding obligation of
the Seller, enforceable against the Seller in accordance with the terms hereof,
subject to (a) applicable bankruptcy, insolvency, reorganization, moratorium and
other laws affecting the enforcement of creditors' rights generally, and (b)
general principles of equity, regardless of whether such enforcement is
considered in a proceeding in equity or at law.

          6. The Seller is not in violation of, and its execution and delivery
of this Agreement and its performance under and compliance with the terms hereof
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 Seller's good
faith and reasonable judgment, is likely to affect materially and adversely
either the ability of the Seller to perform its obligations under this Agreement
or the financial condition of the Seller.

                                     B-1-1

<PAGE>

          7. There are no actions, suits or proceedings pending or, to the best
of the Seller's knowledge, threatened against the Seller which, if determined
adversely to the Seller, would prohibit the Seller from entering into this
Agreement or, in the Seller's good faith and reasonable judgment, would be
likely to affect materially and adversely either the ability of the Seller to
perform its obligations hereunder or the financial condition of the Seller.

          8. No consent, approval, authorization or order of, or filing or
registration with, any state or federal court or governmental agency or body is
required for the consummation by the Seller of the transactions contemplated
herein, except for those consents, approvals, authorizations and orders that
previously have been obtained and those filings and registrations that
previously have been completed, and except for those filings and recordings of
Mortgage Loan Documents and assignments thereof that are contemplated by the
Pooling and Servicing Agreement to be completed after the Closing Date.

          9. The transfer of the Mortgage Loans to the Purchaser as contemplated
herein is not subject to any bulk transfer or similar law in effect in any
applicable jurisdiction.

          10. The Mortgage Loans do not constitute all or substantially all of
the assets of the Seller.

          11. The Seller is not transferring the Mortgage Loans to the Purchaser
with any intent to hinder, delay or defraud its present or future creditors.

          12. The Seller will be solvent at all relevant times prior to, and
will not be rendered insolvent by, its transfer of the Mortgage Loans to the
Purchaser, as contemplated herein.

          13. After giving effect to its transfer of the Mortgage Loans to the
Purchaser, as provided herein, the value of the Seller's assets, either taken at
their present fair saleable value or at fair valuation, will exceed the amount
of the Seller's debts and obligations, including contingent and unliquidated
debts and obligations of the Seller, and the Seller will not be left with
unreasonably small assets or capital with which to engage in and conduct its
business.

          14. The Seller does not intend to, and does not believe that it will,
incur debts or obligations beyond its ability to pay such debts and obligations
as they mature.

          15. No proceedings looking toward liquidation, dissolution or
bankruptcy of the Seller are pending or contemplated.

          16. In connection with its transfer of the Mortgage Loans to the
Purchaser as contemplated herein, the Seller is receiving new value and
consideration constituting at least reasonably equivalent value and fair
consideration.

                                   Exhibit B-2

          Representations and Warranties with Respect to the Purchaser

          The Purchaser hereby represents and warrants that, as of the Closing
Date:

          1. The Purchaser is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware.

          2. The execution and delivery by the Purchaser of, and the performance
by the Purchaser under, this Agreement, and the consummation by the Purchaser of
transactions herein contemplated, will not: (a) violate the Purchaser's
organizational documents; or (b) constitute a default (or an event which, with
notice or lapse of time, or both, would constitute a default) under, or result
in the breach of, any indenture, agreement or other instrument to which the
Purchaser is a party or by which it is bound or which is applicable to it or any
of its assets, which default or breach, in the Purchaser's good faith and
reasonable judgment, is likely to affect materially and adversely either the
ability of the Purchaser to perform its obligations under this Agreement or the
financial condition of the Purchaser.

          3. The Purchaser has full power and authority to enter into and
perform under this Agreement, has duly authorized the execution, delivery and
performance of this Agreement, and has duly executed and delivered this
Agreement.

          4. Assuming due authorization, execution and delivery hereof by the
Seller, this Agreement constitutes a valid, legal and binding obligation of the
Purchaser, enforceable against the Purchaser in accordance with the terms
hereof, subject to (a) applicable bankruptcy, insolvency, reorganization,
moratorium and other laws affecting the enforcement of creditors' rights
generally, and (b) general principles of equity, regardless of whether such
enforcement is considered in a proceeding in equity or at law.

          5. The Purchaser is not in violation of, and its execution and
delivery of this Agreement and its performance under and compliance with the
terms hereof 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
Purchaser's good faith and reasonable judgment, is likely to affect materially
and adversely either the ability of the Purchaser to perform its obligations
under this Agreement or the financial condition of the Purchaser.

          6. There are no actions, suits or proceedings pending or, to the best
of the Purchaser's knowledge, threatened against the Purchaser which, if
determined adversely to the Purchaser, would prohibit the Purchaser from
entering into this Agreement or, in the Purchaser's good faith and reasonable
judgment, would be likely to affect materially and adversely either the ability
of the Purchaser to perform its obligations hereunder or the financial condition
of the Purchaser.

                                     B-2-1

<PAGE>

          7. No consent, approval, authorization or order of, or filing or
registration with, any state or federal court or governmental agency or body is

herein, except for those consents, approvals, authorizations and orders that
previously have been obtained and those filings and registrations that
previously have been completed, and except for those filings of Mortgage Loan
Documents and assignments thereof that are contemplated by the Pooling and
Servicing Agreement to be completed after the Closing Date.

                                    Exhibit C

      Representations and Warranties with Respect to the Exhibit A-1 Loans

          For purposes of these representations and warranties, the phrases "to
the knowledge of the Seller" or "to the Seller's knowledge" shall mean, except
where otherwise expressly set forth below, the actual state of knowledge of the
Seller or any servicer acting on its behalf regarding the matters referred to,
in each case: (i) after the Seller's having conducted such inquiry and due
diligence into such matters as would be customarily performed by prudent
institutional commercial or multifamily, as applicable, mortgage lenders, and in
all events as required by the Seller's underwriting standards, at the time of
the Seller's origination or acquisition of the particular Exhibit A-1 Loan; and
(ii) subsequent to such origination, utilizing the servicing and monitoring
practices customarily utilized by prudent commercial mortgage loan servicers
with respect to securitizable commercial or multifamily, as applicable, mortgage
loans. Also for purposes of these representations and warranties, the phrases
"to the actual knowledge of the Seller" or "to the Seller's actual knowledge"
shall mean, except where otherwise expressly set forth below, the actual state
of knowledge of the Seller or any servicer acting on its behalf without any
express or implied obligation to make inquiry. All information contained in
documents which are part of or required to be part of a Mortgage File shall be
deemed to be within the knowledge and the actual knowledge of the Seller.
Wherever there is a reference to receipt by, or possession of, the Seller of any
information or documents, or to any action taken by the Seller or not taken by
the Seller or its agents or employees, such reference shall include the receipt
or possession of such information or documents by, or the taking of such action
or the not taking such action by, either of the Seller or any servicer acting on
its behalf.

          The Seller hereby represents and warrants with respect to the Exhibit
A-1 Loans that, as of the date hereinbelow specified or, if no such date is
specified, as of the Closing Date, and subject to Section 18 of this Agreement:

          1. Mortgage Loan Schedule. The information set forth in the Mortgage
Loan Schedule with respect to the Exhibit A-1 Loans is true, complete (in
accordance with the requirements of this Agreement and the Pooling and Servicing
Agreement) and correct in all material respects as of the date of this Agreement
and as of the respective Due Dates for the Exhibit A-1 Loans in April 2003.

          2. Ownership of Exhibit A-1 Loans. Immediately prior to the transfer
of the Exhibit A-1 Loans to the Purchaser, the Seller had good title to, and was
the sole owner of, each Exhibit A-1 Loan. The Seller has full right, power and
authority to sell, transfer and assign each Exhibit A-1 Loan to, or at the
direction of, the Purchaser, free and clear of any and all pledges, liens,
charges, security interests, participation interests and/or other interests and
encumbrances (except for certain servicing rights contemplated by this Agreement
or the Pooling and Servicing Agreement). Subject to the completion of the names
and addresses of the assignees and endorsees and any missing recording
information in all instruments of transfer or assignment and endorsements and
the completion of all recording and filing contemplated hereby and by the
Pooling and Servicing Agreement, the Seller will have validly and effectively
conveyed to the

                                      C-1

<PAGE>

Purchaser all legal and beneficial interest in and to each Exhibit A-1 Loan free
and clear of any pledge, lien, charge, security interest or other encumbrance
(except for certain servicing rights contemplated by this Agreement and/or the
Pooling and Servicing Agreement). The sale of the Exhibit A-1 Loans to the
Purchaser or its designee does not require the Seller to obtain any governmental
or regulatory approval or consent that has not been obtained. Each Mortgage Note
in respect of an Exhibit A-1 Loan is, or shall be as of the Closing Date,
properly endorsed to the Purchaser or its designee and each such endorsement is
genuine.

          3. Payment Record. No scheduled payment of principal and interest due
under any Exhibit A-1 Loan on the Due Date in March 2003 and on any Due Date in
the twelve-month period immediately preceding the Due Date for such Exhibit A-1
Loan in March 2003 was 30 days or more delinquent, without giving effect to any
applicable grace period.

          4. Lien; Valid Assignment. The Mortgage related to and delivered in
connection with each Exhibit A-1 Loan constitutes a valid and, subject to the
exceptions set forth in Paragraph 13 below, enforceable first priority lien upon
the related Mortgaged Property, prior to all other liens and encumbrances,
except for the following (collectively, the "Permitted Encumbrances"): (a) the
lien for current real estate taxes, water charges, sewer rents and assessments
not yet due and payable; (b) covenants, conditions and restrictions, rights of
way, easements and other matters that are of public record and are referred to
in the related lender's title insurance policy (or, if not yet issued, referred
to in a pro forma title policy or title policy commitment meeting the
requirements described in Paragraph 8 below); (c) exceptions and exclusions
specifically referred to in the related lender's title insurance policy (or, if
not yet issued, referred to in a pro forma title policy or title policy
commitment meeting the requirements described in Paragraph 8 below); (d) other
matters to which like properties are commonly subject; (e) the rights of tenants
(as tenants only) under leases (including subleases) pertaining to the related
Mortgaged Property; (f) condominium declarations of record and identified in the
related lender's title insurance policy (or, if not yet issued, identified in a
pro forma title policy or title policy commitment meeting the requirements
described in Paragraph 8 below); and (g) if such Exhibit A-1 Loan constitutes a
Cross-Collateralized Mortgage Loan, the lien of the Mortgage for another Exhibit
A-1 Loan contained in the same Cross-Collateralized Group. With respect to each
Exhibit A-1 Loan, such Permitted Encumbrances do not, individually or in the
aggregate, materially interfere with the security intended to be provided by the
related Mortgage, the current principal use of the related Mortgaged Property or
the ability of the related Mortgaged Property to generate income sufficient to
service such Exhibit A-1 Loan. The related assignment of the Mortgage for each
Exhibit A-1 Loan, as contemplated by clause (iv) of the definition of "Mortgage
File" in the Pooling and Servicing Agreement, executed and delivered in favor of
the Trustee, is in recordable form (but for insertion of the name and address of
the assignee and any related recording information which is not yet available to
the Seller), sufficient to validly and effectively convey the assignor's
interest therein and constitutes a legal, valid, binding and, subject to the
exceptions set forth in Paragraph 13 below, enforceable assignment of such
Mortgage from the relevant assignor to the Trustee.

          5. Assignment of Leases. The Mortgage File for each Exhibit A-1 Loan
contains an assignment of leases and rents (an "Assignment of Leases"), either
as a separate instrument or incorporated into the related Mortgage, which
establishes and creates a valid,

                                      C-2

<PAGE>

subsisting and, subject to the exceptions set forth in Paragraph 13 below,
enforceable first priority lien on and security interest in, subject to
applicable law, the property, rights and interests of the related Borrower
described therein, except that a license may have been granted to the related
Borrower to exercise certain rights and perform certain obligations of the
lessor under the relevant lease or leases, including, without limitation, the
right to operate the related leased property; and each assignor thereunder has
the full right to assign the same. The related assignment of any Assignment of
Leases not included in a Mortgage, as contemplated by clause (v) of the
definition of "Mortgage File" in the Pooling and Servicing Agreement, executed
and delivered in favor of the Trustee is in recordable form (but for insertion
of the name and address of the assignee and any related recording information
which is not yet available to the Seller) to validly and effectively convey the
assignor's interest therein and constitutes a legal, valid, binding and, subject
to the exceptions set forth in Paragraph 13 below, enforceable assignment of
such Assignment of Leases from the relevant assignor to the Trustee.

          6. Mortgage Status; Waivers and Modifications. In the case of each
Exhibit A-1 Loan, except by a written instrument which has been delivered to the
Purchaser or its designee as a part of the related Mortgage File, (a) the
related Mortgage (including any amendments or supplements thereto included in
the related Mortgage File) has not been impaired, waived, modified, altered,
satisfied, canceled, subordinated or rescinded, (b) neither the related
Mortgaged Property nor any material portion thereof has been released from the
lien of such Mortgage and (c) the related Borrower has not been released from
its obligations under such Mortgage, in whole or in material part. No
alterations, waivers, modifications or assumptions of any kind have been given,
made or consented to by or on behalf of the Seller with respect to any Exhibit
A-1 Loan since February 17, 2003. The Seller has not taken any affirmative
action that would cause the representations and warranties of the related
Borrower under the Exhibit A-1 Loan not to be true and correct in any material
respect.

          7. Condition of Property; Condemnation. In the case of each Exhibit
A-1 Loan, except as set forth in an engineering report prepared in connection
with the origination of such Exhibit A-1 Loan, the related Mortgaged Property
is, to the Seller's knowledge, in good repair, free and clear of any damage that
would materially and adversely affect its value as security for such Exhibit A-1
Loan (except in any such case where an escrow of funds or insurance coverage
exists sufficient to effect the necessary repairs and maintenance); provided
that, if no engineer or architect physically visited the related Mortgaged
Property in connection with preparing and delivering such engineering report,
then the representation and warranty made in this sentence shall not be
qualified by "to the Seller's knowledge". As of origination of such Exhibit A-1
Loan there was no proceeding pending, and subsequent to such date, the Seller
has not received actual notice of, any proceeding pending for the condemnation
of all or any material portion of the Mortgaged Property securing any Exhibit
A-1 Loan. If any of the engineering reports referred to above in this Paragraph
7 revealed any material damage or material deferred maintenance, then, one of
the following is true: (a) the repairs and/or maintenance necessary to correct
such condition have been completed in all material respects; (b) an escrow of
funds is required or a letter of credit was obtained in an amount reasonably
estimated to be sufficient to complete the repairs and/or maintenance necessary
to correct such condition; or (c) the reasonable estimate of the cost to
complete the repairs and/or maintenance necessary to correct such condition
represented no more than the lesser of (a) 2% of the value of

                                      C-3

<PAGE>

the related Mortgaged Property as reflected in an appraisal conducted in
connection with the origination of the subject Exhibit A-1 Loan and (b) $50,000.
As of the date of the origination of each Exhibit A-1 Loan: (a) all of the
material improvements on the related Mortgaged Property lay wholly within the
boundaries and, to the extent in effect at the time of construction, building
restriction lines of such property, except for encroachments that are insured
against by the lender's title insurance policy referred to in Paragraph 8 below
or that do not materially and adversely affect the value or marketability of
such Mortgaged Property, and (b) no improvements on adjoining properties
materially encroached upon such Mortgaged Property so as to materially and
adversely affect the value or marketability of such Mortgaged Property, except
those encroachments that are insured against by the lender's title insurance
policy referred to in Paragraph 8 below.

          8. Title Insurance. The lien of each Mortgage securing an Exhibit A-1
Loan is insured by an American Land Title Association (or an equivalent form of)
lender's title insurance policy (the "Title Policy") (except that if such policy
is yet to be issued, such insurance may be evidenced by a "marked up" pro forma
policy or title commitment in either case marked as binding and countersigned by
the title company or its authorized agent, either on its face or by an
acknowledged closing instruction or escrow letter) in the original principal
amount of such Exhibit A-1 Loan after all advances of principal, insuring the
originator of the related Exhibit A-1 Loan, its successors and assigns (as the
sole insured) that the related Mortgage is a valid first priority lien on such
Mortgaged Property, subject only to the Permitted Encumbrances. Such Title
Policy (or, if it has yet to be issued, the coverage to be provided thereby) is
in full force and effect, all premiums thereon have been paid, the Seller has
made no claims thereunder and, to the Seller's actual knowledge, no prior holder
of the related Mortgage has made any claims thereunder and no claims have been
paid thereunder. The Seller has not, and to the Seller's actual knowledge, no
prior holder of the related Mortgage has, done, by act or omission, anything
that would materially impair the coverage under such Title Policy. Immediately
following the transfer and assignment of the related Exhibit A-1 Loan to the
Trustee (including endorsement and delivery of the related Mortgage Note to the
Purchaser and recording of the related Assignment of Mortgage in favor of the
Purchaser in the applicable real estate records), such Title Policy (or, if it
has yet to be issued, the coverage to be provided thereby) will inure to the
benefit of the Trustee without the consent of or notice to the insurer. Such
Title Policy contains no exclusion for, or it affirmatively insures (unless the
related Mortgaged Property is located in a jurisdiction where such affirmative
insurance is not available), the following: (a) access to a public road; and (b)
that the area shown on the survey, if any, reviewed or prepared in connection
with the origination of the related Exhibit A-1 Loan is the same as the property
legally described in the related Mortgage. Such Title Policy affirmatively
insures against loss resulting from the forced removal of improvements at the
related Mortgaged Property encroaching on an easement.

          9. No Holdback. The proceeds of each Exhibit A-1 Loan have been fully
disbursed (except in those cases where the full amount of the Exhibit A-1 Loan
has been disbursed but a portion thereof is being held in escrow or reserve
accounts pending the satisfaction of certain conditions relating to leasing,
repairs or other matters with respect to the related Mortgaged Property), and
there is no obligation for future advances with respect thereto. If the related
Mortgage Loan Documents include any requirements regarding (a) the completion

                                      C-4

<PAGE>

of any on-site or off-site improvements and (b) the disbursement of any funds
escrowed for such purpose, and if those requirements were to have been complied
with on or before the Closing Date, then such requirements have been complied
with in all material respects or such funds so escrowed have not been released
except to the extent specifically provided by the related Mortgage Loan
Documents.

          10. Mortgage Provisions. The Mortgage Note, Mortgage and Assignment of
Leases for each Exhibit A-1 Loan, together with applicable state law, contains
customary and, subject to the exceptions set forth in Paragraph 13 below,
enforceable provisions for commercial mortgage loans such as to render the
rights and remedies of the holder thereof adequate for the practical realization
against the related Mortgaged Property of the principal benefits of the security
intended to be provided thereby.

          11. Trustee under Deed of Trust. If the Mortgage for any Exhibit A-1
Loan is a deed of trust, then (a) a trustee, duly qualified under applicable law
to serve as such, has either been properly designated and currently so serves or
may be substituted in accordance with the Mortgage and applicable law, and (b)
no fees or expenses are payable to such trustee by the Seller, the Purchaser or
any transferee thereof except for such fees and expenses (all of which are the
obligation of the related Borrower under the related Mortgage Loan Documents) as
would be payable in connection with a trustee's sale after default by the
related Borrower or in connection with any full or partial release of the
related Mortgaged Property or related security for such Exhibit A-1 Loan.

          12. Environmental Conditions. Except in the case of the Mortgaged
Properties identified on Schedule C-12(Ab/LBP) hereto (as to which properties
the only environmental investigation conducted in connection with the
origination of the related Exhibit A-1 Loan related to asbestos-containing
materials and lead-based paint) and Schedule C-12(TS) hereto (as to which a
transaction screen meeting the requirements of the American Society for Testing
and Materials (a "Transaction Screen") was performed), (a) an environmental site
assessment meeting the requirements of the American Society for Testing and
Materials and covering all environmental hazards typically assessed for similar
properties including use, type and tenants of the Mortgaged Property, or an
update of such an assessment, was performed by a licensed (to the extent
required by applicable state law) environmental consulting firm with respect to
each Mortgaged Property securing an Exhibit A-1 Loan in connection with the
origination of such Exhibit A-1 Loan or, thereafter, (b) except as set forth on
Schedule C-12(OLD) hereto, the report (the "Environmental Report") relating to
such environmental site assessment or update thereof is dated no earlier than
twelve months prior to the Closing Date, (c) a copy of each such Environmental
Report has been delivered to the Purchaser or its designee, and (d) either: (i)
no such Environmental Report provides that as of the date of the report there is
a material violation of any applicable environmental laws with respect to any
circumstances or conditions relating to the related Mortgaged Property; or (ii)
if any such Environmental Report does reveal any such circumstances or
conditions with respect to the related Mortgaged Property and the same have not
been subsequently remediated in all material respects, then, except as described
on Schedule C-12(MV) hereto, one or more of the following are true--(A) one or
more parties not related to or including the related Borrower and collectively
having financial resources reasonably estimated to be adequate to cure the
subject

                                      C-5

<PAGE>

violation in all material respects, were identified as the responsible party or
parties for such condition or circumstance and such condition or circumstance
does not materially impair the value of the Mortgaged Property, (B) the related
Borrower was required to provide additional security reasonably estimated to be
adequate to cure the subject violation in all material respects and/or to obtain
an operations and maintenance plan, (C) the related Borrower, or other
responsible party, provided a "no further action" letter or other evidence
reasonably acceptable to a reasonably prudent commercial mortgage lender that
applicable federal, state or local governmental authorities had no current
intention of taking any action, and are not requiring any action, in respect of
such condition or circumstance, (D) such conditions or circumstances were
investigated further and based upon such additional investigation, an
environmental consultant recommended no further investigation or remediation,
(E) the expenditure of funds reasonably estimated to be necessary to effect such
remediation is not greater than the lesser of (1) 2% of the outstanding
principal balance of the related Exhibit A-1 Loan and (2) $50,000, (F) there
exists an escrow of funds reasonably estimated to be sufficient for purposes of
effecting such remediation, (G) the related Mortgaged Property is identified on
Schedule C-12(EI) hereto and insured under a policy of insurance subject to
reasonable per occurrence and aggregate limits and a reasonable deductible,
against certain losses arising from such circumstances and conditions or (H) a
party with financial resources reasonably estimated to be adequate to cure the
subject violation in all material respects provided a guaranty or indemnity to
the related Borrower to cover the costs of any required investigation, testing,
monitoring or remediation. To the Seller's actual knowledge, there are no
significant or material circumstances or conditions with respect to any
Mortgaged Property not revealed in any such Environmental Report, where
obtained, or in any Borrower questionnaire delivered to the Seller in connection
with the issue of any related environmental insurance policy, if applicable,
that render such Mortgaged Property in material violation of any applicable
environmental laws. The Mortgage Loan Documents for each Exhibit A-1 Loan
require the related Borrower to comply in all material respects with all
applicable federal, state and local environmental laws and regulations. The
Seller has not taken any affirmative action which would cause the Mortgaged
Property securing any Exhibit A-1 Loan not to be in compliance with all federal,
state and local laws pertaining to environmental hazards. Each Borrower
represents and warrants in the related Mortgage Loan Documents generally to the
effect that, except as set forth in certain specified environmental reports and
to the Borrower's knowledge, it has not used, caused or permitted to exist and
will not use, cause or permit to exist on the related Mortgaged Property any
hazardous materials in any manner which violates federal, state or local laws,
ordinances, regulations, orders, directives, or policies governing the use,
storage, treatment, transportation, manufacture, refinement, handling,
production or disposal of hazardous materials. Unless the related Mortgaged
Property is identified on Schedule C-12(EI) hereto, the related Borrower (or an
affiliate thereof) has agreed to indemnify, defend and hold the Seller and its
successors and assigns harmless from and against, or otherwise be liable for,
any and all losses resulting from a breach of environmental representations,
warranties or covenants given by the Borrower in connection with such Exhibit
A-1 Loan, generally including any and all losses, liabilities, damages,
injuries, penalties, fines, expenses and claims of any kind or nature whatsoever
(including without limitation, attorneys' fees and expenses) paid, incurred or
suffered by or asserted against, any such party resulting from such breach.

          13. Loan Document Status. Each Mortgage Note, Mortgage, and other
agreement executed by or on behalf of the related Borrower, or any guarantor of
non-recourse

                                      C-6

<PAGE>

exceptions and environmental liability, with respect to each Exhibit A-1 Loan is
the legal, valid and binding obligation of the maker thereof (subject to any
non-recourse provisions contained in any of the foregoing agreements and any
applicable state anti-deficiency or market value limit deficiency legislation),
enforceable in accordance with its terms, except as such enforcement may be
limited by (i) bankruptcy, insolvency, reorganization, fraudulent transfer and
conveyance or other similar laws affecting the enforcement of creditors' rights
generally and (ii) general principles of equity (regardless of whether such
enforcement is considered in a proceeding in equity or at law), and except that
certain provisions in such loan documents may be further limited or rendered
unenforceable by applicable law, but (subject to the limitations set forth in
the foregoing clauses (i) and (ii)) such limitations will not render such loan
documents invalid as a whole or substantially interfere with the mortgagee's
realization of the principal benefits and/or security provided thereby. There is
no right of rescission, offset, abatement, diminution or valid defense or
counterclaim available to the related Borrower with respect to such Mortgage
Note, Mortgage or other agreements that would deny the mortgagee the principal
benefits intended to be provided thereby. The Seller has no actual knowledge of
any such rights, defenses or counterclaims having been asserted.

          14. Insurance. Except in certain cases, where tenants, having a net
worth of at least $50,000,000 or an investment grade credit rating and obligated
to maintain the insurance described in this paragraph, are allowed to
self-insure the related Mortgaged Properties, all improvements upon each
Mortgaged Property securing a Exhibit A-1 Loan are insured under a fire and
extended perils insurance policy included within the classification "All Risk of
Physical Loss" insurance (or the equivalent) policy in an amount at least equal
to the lesser of the outstanding principal balance of such Exhibit A-1 Loan and
100% of the insurable replacement cost of the improvements located on the
related Mortgaged Property, and if applicable, the related hazard insurance
policy contains appropriate endorsements to avoid the application of
co-insurance and does not permit reduction in insurance proceeds for
depreciation. Each Mortgaged Property securing an Exhibit A-1 Loan is the
subject of a business interruption or rent loss insurance policy providing
coverage for at least twelve (12) months (or a specified dollar amount which is
reasonably estimated to cover no less than twelve (12) months of rental income).
If, based solely on a flood zone certification or a survey of the related
Mortgaged Property, any portion of the improvements on a Mortgaged Property
securing any Exhibit A-1 Loan was, at the time of the origination of such
Exhibit A-1 Loan, in an area identified in the Federal Register by the Flood
Emergency Management Agency as a special flood hazard area (Zone A or Zone V)
(an "SFH Area") and flood insurance was available, then a flood insurance policy
meeting the requirements of the then current guidelines of the Federal Insurance
Administration is in effect with a generally acceptable insurance carrier, in an
amount representing coverage not less than the least of (1) the minimum amount
required, under the terms of coverage, to compensate for any damage or loss on a
replacement basis, (2) the outstanding principal balance of such Exhibit A-1
Loan, and (3) the maximum amount of insurance available under the applicable
National Flood Insurance Administration Program. All such hazard and flood
insurance policies contain a standard mortgagee clause for the benefit of the
holder of the related Mortgage, its successors and assigns, as mortgagee, and
are not terminable (nor may the amount of coverage provided thereunder be
reduced) without ten (10) days' prior written notice to the mortgagee; and no
such notice has been received, including any notice of nonpayment of premiums,
that has not been cured and, to the Seller's actual knowledge, all such
insurance is in full force and effect. Each

                                      C-7

<PAGE>

Mortgaged Property and all improvements thereon are also covered by
comprehensive general liability insurance in such amounts as are generally
required by reasonably prudent commercial lenders for similar properties and
seismic insurance to the extent any Mortgaged Property has a probable maximum
loss of greater than twenty percent (20%) of the replacement value of the
related improvements, calculated using methodology acceptable to a reasonably
prudent commercial mortgage lender with respect to similar properties in same
area or earthquake zone. If the Mortgaged Property for any Exhibit A-1 Loan is
located in Florida or within 25 miles of the coast in Texas, Louisiana,
Mississippi, Alabama, Georgia, North Carolina or South Carolina, then such
Mortgaged Property is insured by windstorm insurance in an amount at least equal
to the lesser of (i) the outstanding principal balance of such Exhibit A-1 Loan
and (ii) 100% of the insurable replacement cost of the improvements located on
the related Mortgaged Property. If any Mortgaged Property is, to the Seller's
knowledge, a materially non-conforming use or structure under applicable zoning
laws and ordinances, then, in the event of a material casualty or destruction,
one or more of the following is true: (i) such Mortgaged Property may be
restored or repaired to materially the same extent of the use or structure at
the time of such casualty; (ii) such Mortgaged Property is covered by law and
ordinance insurance in an amount customarily required by reasonably prudent
commercial mortgage lenders; or (iii) the amount of hazard insurance currently
in place and required by the related Mortgage Loan Documents would generate
proceeds sufficient to pay off the subject Exhibit A-1 Loan. Additionally, for
any Exhibit A-1 Loan having a Cut-off Date Principal Balance equal to or greater
than $20,000,000, the insurer for all of the required coverages set forth herein
has a claims paying ability rating from Standard & Poor's Ratings Services, a
division of The McGraw-Hill Companies, Inc., Moody's or Fitch of not less than
A-minus (or the equivalent), or from A.M. Best of not less than "A:V" (or the
equivalent). With respect to each Exhibit A-1 Loan, the related Mortgage Loan
Documents require that the related Borrower or a tenant of such Borrower
maintain insurance as described above or permit the Mortgagee to require
insurance as described above. Except under circumstances that would be
reasonably acceptable to a prudent commercial mortgage lender or that would not
otherwise materially and adversely affect the security intended to be provided
by the related Mortgage, the Mortgage Loan Documents for each Exhibit A-1 Loan
provide that proceeds paid under any such casualty insurance policy will (or, at
the lender's option, will) be applied either to the repair or restoration of the
related Mortgaged Property or to the payment of amounts due under such Exhibit
A-1 Loan; provided that the related Mortgage Loan Documents may entitle the
related Borrower to any portion of such proceeds remaining after the repair or
restoration of the related Mortgaged Property or payment of amounts due under
the Exhibit A-1 Loan; and provided, further, that, if the related Borrower holds
a leasehold interest in the related Mortgaged Property, the application of such
proceeds will be subject to the terms of the related Ground Lease (as defined in
Paragraph 18 below). To the Seller's actual knowledge, all insurance policies
described above are with an insurance carrier qualified to write insurance in
the relevant jurisdiction.

          15. Taxes and Assessments. As of the date of origination of the
subject Exhibit A-1 Loan or the Cut-off Date, whichever is later, there were no
(and, to the Seller's actual knowledge, as of the Closing Date, there are no)
delinquent property taxes or assessments or other outstanding charges affecting
any Mortgaged Property securing an Exhibit A-1 Loan that are not otherwise
covered by an escrow of funds sufficient to pay such charge. For purposes

                                      C-8

<PAGE>

of this representation and warranty, real property taxes and assessments shall
not be considered delinquent until the date on which interest and/or penalties
would be payable thereon.

          16. Borrower Bankruptcy. No Mortgaged Property securing an Exhibit A-1
Loan is the subject of, and no Borrower under an Exhibit A-1 Loan is a debtor
in, any state or federal bankruptcy, insolvency or similar proceeding.

          17. Local Law Compliance. To the Seller's knowledge, based upon a
letter from governmental authorities, a legal opinion, a zoning consultant's
report, an endorsement to the related Title Policy, or a representation of the
related Borrower at the time of origination of the subject Exhibit A-1 Loan, or
based on such other due diligence considered reasonable by prudent commercial
mortgage lenders in the lending area where the subject Mortgaged Property is
located, the improvements located on or forming part of, and the existing use
of, each Mortgaged Property securing an Exhibit A-1 Loan are in material
compliance with applicable zoning laws and ordinances or constitute a legal
non-conforming use or structure (or, if any such improvement does not so comply
and does not constitute a legal non-conforming use or structure, such
non-compliance and failure does not materially and adversely affect the value of
the related Mortgaged Property as determined by the appraisal performed in
connection with the origination of such Exhibit A-1 Loan).

          18. Leasehold Estate Only. If any Exhibit A-1 Loan is secured by the
interest of a Borrower as a lessee under a ground lease (together with any and
all written amendments and modifications thereof and any and all estoppels from
or other agreements with the ground lessor, a "Ground Lease"), but not by the
related fee interest in the subject real property (the "Fee Interest"), then:

          (a) such Ground Lease or a memorandum thereof has been or will be duly
recorded; such Ground Lease permits the interest of the lessee thereunder to be
encumbered by the related Mortgage and does not restrict the use of the related
Mortgaged Property by such lessee, its successors or assigns in a manner that
would materially adversely affect the security provided by the related Mortgage;
and there has been no material change in the terms of such Ground Lease since
its recordation, with the exception of material changes reflected in written
instruments which are a part of the related Mortgage File;

          (b) the related lessee's leasehold interest in the portion of the
related Mortgaged Property covered by such Ground Lease is not subject to any
liens or encumbrances superior to, or of equal priority with, the related
Mortgage, other than Permitted Encumbrances, and such Ground Lease provides that
it shall remain superior to any mortgage or other lien upon the related Fee
Interest;

          (c) the Borrower's interest in such Ground Lease is assignable to, and
is thereafter further assignable by, the Purchaser upon notice to, but without
the consent of, the lessor thereunder (or, if such consent is required, it has
been obtained); provided that such Ground Lease has not been terminated and all
defaults, if any, on the part of the related lessee have been cured;

                                      C-9

<PAGE>

          (d) such Ground Lease is in full force and effect, the Seller has not
received, as of the Closing Date, actual notice that such Ground Lease is not in
full force and effect or that any material default has occurred under such
Ground Lease, and the lessor under such Ground Lease has been sent notice of the
lien evidenced by the Mortgage in accordance with the terms of the Ground Lease;

          (e) such Ground Lease requires the lessor thereunder to give notice of
any default by the lessee to the mortgagee under such Exhibit A-1 Loan; and
furthermore, except as set forth on Schedule C-18(e) hereto, such Ground Lease
further provides that no notice of termination given under such Ground Lease is
effective against the mortgagee under such Exhibit A-1 Loan unless a copy has
been delivered to such mortgagee in the manner described in such Ground Lease;

          (f) the mortgagee under such Exhibit A-1 Loan is permitted a
reasonable opportunity (including, where necessary, sufficient time to gain
possession of the interest of the lessee under such Ground Lease) to cure any
default under such Ground Lease, which is curable after the receipt of notice of
any such default, before the lessor thereunder may terminate such Ground Lease;

          (g) except as set forth on Schedule C-18(g) hereto, such Ground Lease
has an original term (or an original term plus options exercisable by the holder
of the related Mortgage) which extends not less than twenty (20) years beyond
the end of the amortization term of such Exhibit A-1 Loan;

          (h) such Ground Lease requires the lessor to enter into a new lease
with a mortgagee upon termination of such Ground Lease as a result of a
rejection of such Ground Lease in a bankruptcy proceeding involving the related
Borrower unless the mortgagee under such Exhibit A-1 Loan fails to cure a
default of the lessee under such Ground Lease following notice thereof from the
lessor;

          (i) except as described on Schedule C-18(i) hereto, under the terms of
such Ground Lease and the related Mortgage Loan Documents, taken together, any
casualty insurance proceeds, other than de minimis amounts for minor casualties,
with respect to the leasehold interest will be applied either: (i) to the repair
or restoration of all or part of the related Mortgaged Property, with the
mortgagee or a trustee appointed by it having the right to hold and disburse
such proceeds as the repair or restoration progresses (except in such cases
where a provision entitling another party to hold and disburse such proceeds
would not be viewed as commercially unreasonable by a prudent commercial
mortgage lender), or (ii) to the payment of the outstanding principal balance of
the Exhibit A-1 Loan together with any accrued interest thereon; and under the
terms of such Ground Lease and the related Mortgage Loan Documents, taken
together, any condemnation proceeds or awards in respect of a total or
substantially total taking will be applied first to the payment of the
outstanding principal and interest on the Exhibit A-1 Loan (except as otherwise
provided by applicable law) and subject to any rights to require the
improvements to be rebuilt;

                                      C-10

<PAGE>

          (j) such Ground Lease does not impose any restrictions on subletting
which would be viewed as commercially unreasonable by a prudent commercial
mortgage lender in the lending area where the related Mortgaged Property is
located at the time of the origination of such Exhibit A-1 Loan;

          (k) except as set forth on Schedule C-18(k) hereto, the lessor under
such Ground Lease is not permitted to disturb the possession, interest or quiet
enjoyment of the lessee in the relevant portion of the Mortgaged Property
subject to such Ground Lease for any reason, or in any manner, which would
materially adversely affect the security provided by the related Mortgage; and

          (l) except as set forth on Schedule C-18(l) hereto, such Ground Lease
provides that it may not be amended or modified without the prior consent of the
mortgagee under such Exhibit A-1 Loan and that any such action without such
consent is not binding on such mortgagee, its successors or assigns.

          19. Qualified Mortgage. Such Exhibit A-1 Loan is a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code and Treasury
regulation section 1.860G-2(a), and the related Mortgaged Property, if acquired
in connection with the default or imminent default of such Exhibit A-1 Loan,
would constitute "foreclosure property" within the meaning of Section
860G(a)(8).

          20. Advancement of Funds. The Seller has not advanced funds, or
induced, solicited or knowingly received any advance of funds from a party other
than the owner of the related Mortgaged Property (or a tenant at or the property
manager of the related Mortgaged Property), for the payment of any amount
required by such Exhibit A-1 Loan, except for interest accruing from the date of
origination of such Exhibit A-1 Loan or the date of disbursement of the Exhibit
A-1 Loan proceeds, whichever is later, to the date which preceded by 30 days the
first due date under the related Mortgage Note.

          21. No Equity Interest, Equity Participation or Contingent Interest.
No Exhibit A-1 Loan contains any equity participation by the mortgagee
thereunder, is convertible by its terms into an equity ownership interest in the
related Mortgaged Property or the related Borrower, has a shared appreciation
feature, provides for any contingent or additional interest in the form of
participation in the cash flow of the related Mortgaged Property, or, except as
identified on Schedule C-21 hereto, provides for interest-only payments without
principal amortization for more than six months or for the negative amortization
of interest, except that, in the case of an ARD Loan, such Exhibit A-1 Loan
provides that, during the period commencing on or about the related Anticipated
Repayment Date and continuing until such Exhibit A-1 Loan is paid in full, (a)
additional interest shall accrue, may be compounded monthly and shall be payable
only after the outstanding principal of such Exhibit A-1 Loan is paid in full,
and (b) a portion of the cash flow generated by such Mortgaged Property will be
applied each month to pay down the principal balance thereof in addition to the
principal portion of the related Monthly Payment. Neither the Seller nor any
affiliate thereof has any obligation to make any capital contribution to the
Borrower under the Exhibit A-1 Loan or otherwise.

                                      C-11

<PAGE>

          22. Legal Proceedings. To the Seller's knowledge, as of origination of
the Exhibit A-1 Loan, except as set forth on Schedule C-22 hereto, there were
no, and to the Seller's actual knowledge, as of the Closing Date, there are no
pending actions, suits, litigation or other proceedings by or before any court
or governmental authority against or affecting the Borrower (or any guarantor to
the extent a reasonably prudent commercial or multifamily, as applicable,
mortgage lender would consider such guarantor material to the underwriting of
such Exhibit A-1 Loan) under any Exhibit A-1 Loan or the related Mortgaged
Property that, if determined adversely to such Borrower or Mortgaged Property,
would materially and adversely affect the value of the Mortgaged Property as
security for such Exhibit A-1 Loan, the Borrower's ability to pay principal,
interest or any other amounts due under such Exhibit A-1 Loan or the ability of
any such guarantor to meet its obligations.

          23. Other Mortgage Liens. Except as otherwise set forth on Schedule
C-23 hereto, none of the Exhibit A-1 Loans permits the related Mortgaged
Property or any direct controlling equity interest in the related Borrower to be
encumbered by any mortgage lien or, in the case of a direct controlling equity
interest in the related Borrower, a lien to secure any other debt, without the
prior written consent of the holder of the subject Exhibit A-1 Loan or the
satisfaction of debt service coverage or similar criteria specified therein. To
the Seller's knowledge, as of origination of the subject Exhibit A-1 Loan, and
to the Seller's actual knowledge, as of the Closing Date, except as otherwise
set forth on Schedule C-23 hereto, and except for cases involving other Exhibit
A-1 Loans, no Mortgaged Property securing the subject Exhibit A-1 Loan is
encumbered by any other mortgage liens (other than Permitted Encumbrances) and
no direct controlling equity interest in the related Borrower is encumbered by a
lien to secure any other debt. The related Mortgage Loan Documents require the
Borrower under each Exhibit A-1 Loan to pay all reasonable costs and expenses
related to any required consent to an encumbrance, including reasonable legal
fees and expenses and any applicable Rating Agency fees, or would permit the
subject mortgagee to withhold such consent if such costs and expenses are not
paid by a party other than such mortgagee.

          24. No Mechanics' Liens. To the Seller's knowledge, as of the
origination of the Exhibit A-1 Loan, and, to the Seller's actual knowledge, as
of the Closing Date, except as set forth on Schedule C-24 hereto: (i) each
Mortgaged Property securing an Exhibit A-1 Loan (exclusive of any related
personal property) is free and clear of any and all mechanics' and materialmen's
liens that are prior or equal to the lien of the related Mortgage and that are
not bonded or escrowed for or covered by title insurance, and (ii) no rights are
outstanding that under law could give rise to any such lien that would be prior
or equal to the lien of the related Mortgage and that is not bonded or escrowed
for or covered by title insurance.

          25. Compliance with Usury Laws. Each Exhibit A-1 Loan complied with,
or was exempt from, all applicable usury laws in effect at its date of
origination.

          26. Licenses and Permits. To the extent required by applicable law,
each Exhibit A-1 Loan requires the related Borrower to be qualified to do
business, and requires the related Borrower and the related Mortgaged Property
to be in material compliance with all regulations, licenses, permits,
authorizations, restrictive covenants and zoning and building laws, in each case
to the extent required by law or to the extent that the failure to be so
qualified or in

                                      C-12

<PAGE>

compliance would have a material and adverse effect upon the enforceability of
the Exhibit A-1 Loan or upon the practical realization against the related
Mortgaged Property of the principal benefits of the security intended to be
provided thereby. To the Seller's knowledge, as of the date of origination of
each Exhibit A-1 Loan and based on any of: (i) a letter from governmental
authorities, (ii) a legal opinion, (iii) an endorsement to the related Title
Policy, (iv) a representation of the related Borrower at the time of origination
of such Exhibit A-1 Loan, (v) a zoning report from a zoning consultant, or (vi)
other due diligence that the originator of the Exhibit A-1 Loan customarily
performs in the origination of comparable mortgage loans, the related Borrower
was in possession of all material licenses, permits and franchises required by
applicable law for the ownership and operation of the related Mortgaged Property
as it was then operated or such material licenses, permits and franchises have
otherwise been issued.

          27. Cross-Collateralization. No Exhibit A-1 Loan is
cross-collateralized with any loan which is outside the Mortgage Pool. With
respect to any group of cross-collateralized Exhibit A-1 Loans, the sum of the
amounts of the respective Mortgages recorded on the related Mortgaged Properties
with respect to such Exhibit A-1 Loans is at least equal to the total amount of
such Exhibit A-1 Loans.

          28. Releases of Mortgaged Properties. Except as set forth on Schedule
C-28A hereto, no Mortgage Note or Mortgage for any Exhibit A-1 Loan requires the
mortgagee to release all or any material portion of the related Mortgaged
Property from the lien of the related Mortgage except upon: (i) payment in full
of all amounts due under the related Exhibit A-1 Loan or (ii) delivery of
"government securities" within the meaning of Treas. Reg. Section
1.860G-2(a)(8)(i) in connection with a defeasance of the related Exhibit A-1
Loan; provided that the Exhibit A-1 Loans that are Cross-Collateralized Mortgage
Loans, and the other individual Exhibit A-1 Loans secured by multiple parcels,
may require the respective mortgagee(s) to grant releases of material portions
of the related Mortgaged Property or the release of one or more related
Mortgaged Properties upon: (i) the satisfaction of certain legal and
underwriting requirements, (ii) the payment of a release price (in an amount
that is, except as otherwise set forth on Schedule C-28B hereto, at least equal
to 125% of the allocated loan amount for the released property or parcel) and
prepayment consideration in connection therewith or (iii) the delivery of
substitute real estate collateral. No release or partial release of any
Mortgaged Property, or any portion thereof, expressly permitted pursuant to the
terms of any Mortgage Note or Mortgage will constitute a significant
modification of the related Exhibit A-1 Loan under Treas. Reg. Section
1.860G-2(b)(2).

          29. Defeasance. With respect to any Exhibit A-1 Loan that contains a
provision for any defeasance of mortgage collateral (a "Defeasance Loan"),
except as set forth on Schedule C-29A hereto, the related Mortgage Note or
Mortgage provides that the defeasance option is not exercisable prior to a date
that is at least two (2) years following the Closing Date and is otherwise in
compliance with applicable statutes, rules and regulations governing REMICs;
requires prior written notice to the holder of the Exhibit A-1 Loan of the
exercise of the defeasance option and payment by the Borrower of all related
reasonable fees, costs and expenses as set forth below; if the Borrower would
continue to own assets in addition to the defeasance collateral, requires, or
permits the lender to require, the Exhibit A-1 Loan (or the portion thereof
being defeased) to be assumed by a single-purpose entity; and requires counsel
to

                                      C-13

<PAGE>

provide a legal opinion that the Purchaser has a perfected security interest in
such collateral prior to any other claim or interest. In addition, each Exhibit
A-1 Loan that is a Defeasance Loan permits defeasance only with substitute
collateral constituting "government securities" within the meaning of Treas.
Reg. Section 1.860G-2(a)(8)(i) in an amount sufficient to make all scheduled
payments under the Mortgage Note (or the portion thereof being defeased) when
due, and in the case of ARD Loans, assuming the Anticipated Repayment Date is
the Maturity Date. To the Seller's actual knowledge, defeasance under the
Exhibit A-1 Loan is only for the purpose of facilitating the disposition of a
Mortgaged Property and not as part of an arrangement to collateralize a REMIC
offering with obligations that are not real estate mortgages. With respect to
each Defeasance Loan, the related Mortgage Loan Documents provide that the
related Borrower shall (a) pay all Rating Agency fees associated with defeasance
(if rating confirmation is a specific condition precedent thereto) and all other
reasonable expenses associated with defeasance, including, but not limited to,
accountant's fees and opinions of counsel, or (b) provide all opinions required
under the related loan documents, including, if applicable, a REMIC opinion and
a perfection opinion and any applicable rating agency letters confirming no
downgrade or qualification of ratings on any classes in the transaction.
Additionally, for any Exhibit A-1 Loan having a Cut-off Date Principal Balance
equal to or greater than $19,900,000, the Exhibit A-1 Loan or the related
documents require confirmation from the Rating Agency that exercise of the
defeasance option will not cause a downgrade or withdrawal of the rating
assigned to any securities backed by the Exhibit A-1 Loan and require the
Borrower to pay any Rating Agency fees and expenses.

          30. Fixed Rate Loans. Each Exhibit A-1 Loan bears interest at a rate
that remains fixed throughout the remaining term of such Exhibit A-1 Loan,
except in the case of an ARD Loan after its Anticipated Repayment Date and
except for the imposition of a default rate.

          31. Inspection. The Seller, an affiliate of the Seller, or a
correspondent in the conduit funding program of the Seller, inspected, or caused
the inspection of, each Mortgaged Property securing an Exhibit A-1 Loan within
twelve (12) months of the Closing Date.

          32. No Material Default. To the Seller's knowledge, there exists no
material default, breach, violation or event of acceleration under the Mortgage
Note or Mortgage for any Exhibit A-1 Loan; provided, however, that this
representation and warranty does not cover any default, breach, violation or
event of acceleration that specifically pertains to or arises out of the subject
matter otherwise covered by any other representation and warranty made by the
Seller in this Exhibit C.

          33. Due-on-Sale. Except as set forth on Schedule C-33 hereto, the
Mortgage for each Exhibit A-1 Loan contains a "due-on-sale" clause, which
provides for the acceleration of the payment of the unpaid principal balance of
such Exhibit A-1 Loan if, without the prior written consent of the holder of
such Mortgage, either the related Mortgaged Property, or any direct controlling
equity interest in the related Borrower, is transferred or sold, other than by
reason of family and estate planning transfers, transfers of less than a
controlling interest in the Borrower, transfers of shares in public companies,
issuance of non-controlling new equity interests, transfers to an affiliate
meeting the requirements of the Exhibit A-1 Loan, transfers among existing
members, partners or shareholders in the Borrower, transfers among affiliated

                                      C-14

<PAGE>

Borrowers with respect to cross-collateralized Exhibit A-1 Loans or
multi-property Exhibit A-1 Loans, transfers among co-Borrowers or transfers of a
similar nature to the foregoing meeting the requirements of the Exhibit A-1
Loan. The related Mortgage Loan Documents require the Borrower under each
Exhibit A-1 Loan to pay all reasonable fees and expenses associated with
securing the consent or approval of the holder of the related Mortgage for all
actions requiring such consent or approval under the related Mortgage, including
the cost of counsel opinions relating to REMIC or other securitization and tax
issues or require the payment of a specified fee or fees, including a 1%
assumption fee that would be applied to pay such fees and expenses.

          34. Single Purpose Entity. Each Exhibit A-1 Loan with an original
principal balance over $5,000,000.00 requires the related Borrower to be, at
least for so long as the Exhibit A-1 Loan is outstanding, and to the Seller's
actual knowledge, the related Borrower is, a Single-Purpose Entity. For this
purpose, "Single-Purpose Entity" means a Person, other than an individual, which
is formed or organized solely for the purpose of owning and operating the
related Mortgaged Property or Properties; does not engage in any business
unrelated to such Mortgaged Property or Properties and the financing thereof;
and whose organizational documents provide, or which entity represented and
covenanted in the related Mortgage Loan Documents, substantially to the effect
that such Borrower (i) does not and will not have any material assets other than
those related to its interest in such Mortgaged Property or Properties or the
financing thereof; (ii) does not and will not have any indebtedness other than
as permitted by the related Mortgage or other related Mortgage Loan Documents;
(iii) maintains its own books, records and accounts, in each case which are
separate and apart from the books, records and accounts of any other person; and
(iv) holds itself out as being a legal entity, separate and apart from any other
person. In addition, each Exhibit A-1 Loan with a Cut-off Date Principal Balance
of $20,000,000 or more, the related Borrower's organizational documents provide
substantially to the effect that the Borrower shall: conduct business in its own
name; not guarantee or assume the debts or obligations of any other person; not
commingle its assets or funds with those of any other person; prepare separate
tax returns and financial statements, or if part of a consolidated group, be
shown as a separate member of such group; transact business with affiliates on
an arm's length basis; hold itself out as being a legal entity, separate and
apart from any other person, and such organizational documents further provide
substantially to the effect that: any dissolution and winding up or insolvency
filing for such entity is prohibited or requires the consent of an independent
director or member or the unanimous consent of all partners or members, as
applicable; such documents may not be amended with respect to the Single-Purpose
Entity requirements without the approval of the mortgagee or rating agencies;
the Borrower shall have an outside independent director or member. The Seller
has obtained, with respect to each Exhibit A-1 Loan having a Cut-off Date
Principal Balance of $20,000,000 or more, in connection with its origination or
acquisition thereof, a counsel's opinion regarding non-consolidation of the
Borrower in any insolvency proceeding involving any other party. To the Seller's
actual knowledge, each Borrower has fully complied with the requirements of the
related Mortgage Note and Mortgage and the Borrower's organizational documents
regarding Single-Purpose-Entity status. The organization documents of any
Borrower on an Exhibit A-1 Loan having a Cut-off Date Principal Balance of
$20,000,000 or more that is a single member limited liability company, provide
that the Borrower shall not dissolve or liquidate upon the bankruptcy,
dissolution, liquidation or death of the sole member. Any such single member
limited liability company Borrower is organized in jurisdictions that provide
for such continued existence, and

                                      C-15

<PAGE>

the Seller has obtained, in connection with its origination or acquisition of
the subject Exhibit A-1 Loan, an opinion of such Borrower's counsel confirming
such continued existence and that the applicable law provides that creditors of
the single member may only attach the assets of the member including the
membership interests in the Borrower but not the assets of the Borrower.

          35. Whole Loan. Each Exhibit A-1 Loan is a whole loan and not a
participation interest in a mortgage loan.

          36. Tax Parcels. Each Mortgaged Property constitutes one or more
complete separate tax lots containing no other property, or is subject to an
endorsement under the related Title Policy insuring same, or an application for
the creation of separate tax lots complying in all respects with the applicable
laws and requirements of the applicable governing authority has been made and
approved by the applicable governing authority and such separate tax lots shall
be effective for the next tax year.

          37. ARD Loans. Except as described on Schedule C-37 hereto, each
Exhibit A-1 Loan which is an ARD Loan commenced amortizing on its initial
scheduled Due Date, and provides that: (i) its Mortgage Rate will increase by at
least two (2) percentage points in connection with the passage of its
Anticipated Repayment Date; (ii) its Anticipated Repayment Date is not less than
seven (7) years following the origination of such Exhibit A-1 Loan; (iii) no
later than the related Anticipated Repayment Date, the related Borrower is
required (if it has not previously done so) to enter into a "lockbox agreement"
whereby all revenue from the related Mortgaged Property shall be deposited
directly into a designated account controlled by the Master Servicer; and (iv)
any net cash flow from the related Mortgaged Property that is applied to
amortize such Exhibit A-1 Loan following its Anticipated Repayment Date shall,
to the extent such net cash flow is in excess of the scheduled principal and
interest payment payable therefrom, be net of budgeted and discretionary
(servicer approved) capital expenditures.

          38. Security Interests. The security agreements, financing statements
or other instruments, if any, related to the Exhibit A-1 Loan establish and
create, and a UCC financing statement has been filed and/or recorded in all
places required by applicable law for the perfection of (to the extent that the
filing of such a UCC financing statement can perfect such a security interest),
a valid security interest in the personal property granted under such Mortgage
(and any related security agreement), which in all cases includes elevators and
all Borrower-owned furniture, fixtures and equipment material to the operation
and use of the Mortgaged Property as presently operated, and if such Mortgaged
Property is a hotel operated by the related Borrower, then such personal
property constitutes such portion of the material personal property required to
operate the Borrower's business as the Seller considered appropriate in light of
its underwriting standards; any security agreement, chattel mortgage or
equivalent document related to and delivered in connection with the Exhibit A-1
Loan establishes and creates a valid and enforceable lien and security interest
on the property described therein (subject to the exceptions set forth in
Paragraph 13 above), which lien/security interest shall, in the case of (i)
elevators at all Mortgaged Properties having the same and (ii) all
Borrower-owned furniture, fixtures and equipment at Borrower operated hotel
properties, be a first priority lien/security interest except for certain
personal property subject to purchase money security interests and personal
property leases. In the case of any Exhibit A-1 Loan secured by a hotel, the
related loan documents

                                      C-16

<PAGE>

contain such provisions as are necessary and UCC financing statements have been
filed as necessary, in each case, to perfect a valid first priority security
interest in the related revenues with respect to such Mortgaged Property. An
assignment of each UCC financing statement relating to the Exhibit A-1 Loan has
been executed by the Seller in blank which the Purchaser or its designee is
authorized to complete and to file in the filing office in which such financing
statement was filed. Each Exhibit A-1 Loan and the related Mortgage (along with
any security agreement and UCC financing statement), together with applicable
state law, contain customary and enforceable provisions such as to render the
rights and remedies of the holders thereof adequate for the practical
realization against the personal property described above, and the principal
benefits of the security intended to be provided thereby.

          39. Disclosure to Environmental Insurer and Other Matters. If the
Mortgaged Property securing any Exhibit A-1 Loan is covered by a secured
creditor impaired property policy, then the Seller:

          (a) has disclosed, or is aware that there has been disclosed, in the
     application for such policy or otherwise to the insurer under such policy
     the "pollution conditions" (as defined in such policy) identified in any
     environmental reports related to such Mortgaged Property which are in the
     Seller's possession or are otherwise known to the Seller; and

          (b) has delivered or caused to be delivered to the insurer under such
     policy copies of all environmental reports in the Seller's possession
     related to such Mortgaged Property;

in each case to the extent required by such policy or to the extent the failure
to make any such disclosure or deliver any such report would materially and
adversely affect the Purchaser's ability to recover under such policy. If the
Mortgaged Property securing any Exhibit A-1 Loan is covered by a secured
creditor impaired property policy, then: (x) all premiums for such insurance
have been paid; (y) such insurance is in full force and effect; and (z) (i) an
environmental report, a property condition report or an engineering report was
prepared that included an assessment for lead based paint ("LBP") (in the case
of a multifamily property built prior to 1978), asbestos containing materials
("ACM") (in the case of any property built prior to 1985) and radon gas ("RG")
(in the case of a multifamily property) at such Mortgaged Property and (ii) if
such report disclosed the existence of a material and adverse LBP, ACM or RG
environmental condition or circumstance affecting such Mortgaged Property, then,
(A) the related Borrower was required to remediate such condition or
circumstance prior to the closing of the subject Exhibit A-1 Loan, or (B) the
related Borrower was required to provide additional security reasonably
estimated to be adequate to cure such condition or circumstance, or (C) the
related Mortgage Loan Documents require the related Borrower to establish an
operations and maintenance plan with respect to such condition or circumstance
after the closing of such Exhibit A-1 Loan. If the Exhibit A-1 Loan is listed on
Schedule C-12(EI) hereto and the environmental insurance for such Exhibit A-1
Loan is not a secured creditor policy but was required to be obtained by the
Borrower, then the holder of the Exhibit A-1 Loan is entitled to be an
additional insured under such policy, all premiums have been paid, such
insurance is in full force and effect

                                      C-17

<PAGE>

and, to the Seller's knowledge, the Borrower has made the disclosures and
complied with the requirements of clauses (a) and (b) of this Paragraph 39.

          40. Prepayment Premiums and Yield Maintenance Charges. Prepayment
Premiums and Yield Maintenance Charges payable with respect to each Exhibit A-1
Loan, if any, constitute "customary prepayment penalties" within meaning of
Treas. Reg. Section 1.860G-1(b)(2).

          41. Operating Statements. Except for the Exhibit A-1 Loans with an
initial principal balance less than $3,000,000, which may only require annual
statements, each Exhibit A-1 Loan requires the Borrower, in some cases only at
the request of the holder of the related Mortgage, to provide the owner or
holder of the related Mortgage with at least quarterly and annual operating
statements, rent rolls (if there is more than one tenant) and related
information and annual financial statements, which annual financial statements
with respect to each Exhibit A-1 Loan with an original principal balance greater
than $20 million shall be audited (or prepared and certified) by an independent
certified public accountant upon the request of the holder of the related
Mortgage.

          42. Servicing Rights. Except as otherwise contemplated in this
Agreement or the Pooling and Servicing Agreement, no Person has been granted or
conveyed the right to service any Exhibit A-1 Loan or receive any consideration
in connection therewith.

          43. Recourse. Except as set forth on Schedule C-43A hereto, each
Exhibit A-1 Loan is non-recourse; provided that, except as described on Schedule
C-43B hereto or for Exhibit A-1 Loans with a Cut-off Date Principal Balance of
less than $5,000,000, the Borrower and either a principal of the Borrower or
other individual guarantor, with assets other than any interest in the Borrower,
is liable in the event of (i) fraud or material misrepresentation, (ii)
misapplication or misappropriation of rents, insurance payments, condemnation
awards or tenant security deposits, (iii) violation of applicable environmental
laws or breaches of environmental covenants or (iv) the filing of a voluntary
bankruptcy or insolvency proceeding by the Borrower; and provided, further,
that, with respect to clause (iii) of the preceding proviso, an indemnification
against losses related to such violations or environmental insurance shall
satisfy such requirement. No waiver of liability for such non-recourse
exceptions has been granted to the Borrower or any such guarantor or principal
by the Seller or anyone acting on behalf of the Seller.

          44. Assignment of Collateral. There is no material collateral securing
any Exhibit A-1 Loan that has not been assigned to the Purchaser.

          45. Fee Simple or Leasehold Interests. The interest of the related
Borrower in the Mortgaged Property securing each Exhibit A-1 Loan includes a fee
simple and/or leasehold estate or interest in real property and the improvements
thereon.

          46. Servicing. The servicing and collection practices used with
respect to each Exhibit A-1 Loan in all material respects have met customary
standards utilized by prudent commercial mortgage loan servicers with respect to
whole loans.

                                      C-18

<PAGE>

          47. Originator's Authorization To Do Business. To the extent required
under applicable law, as of the Exhibit A-1 Loan's funding date and at all times
when it held such Exhibit A-1 Loan, the originator of each Exhibit A-1 Loan was
authorized to do business in the jurisdiction in which the related Mortgaged
Property is located, except where the failure to be so authorized does not
adversely affect the enforceability of such Exhibit A-1 Loan.

          48. No Fraud In Origination. In the origination of the Exhibit A-1
Loan, neither the originator nor any employee or agent of the Seller or the
originator, participated in any fraud or intentional material misrepresentation
with respect to the Borrower, the Mortgaged Property or any guarantor. To the
Seller's actual knowledge, no Borrower is guilty of defrauding or making an
intentional material misrepresentation to the Seller or originator with respect
to the origination of the Exhibit A-1 Loan, the Borrower or the Mortgaged
Property.

          49. Appraisal. In connection with its origination or acquisition of
each Exhibit A-1 Loan, the Seller obtained an appraisal of the related Mortgaged
Property, which appraisal is signed by an appraiser, who, to the Seller's actual
knowledge, had no interest, direct or indirect, in the Borrower, the Mortgaged
Property or in any loan made on the security of the Mortgaged Property, and
whose compensation is not affected by the approval or disapproval of the Exhibit
A-1 Loan; to the Seller's knowledge, the appraisal and appraiser both satisfy
the requirements of the "Uniform Standards of Professional Appraisal Practice"
as adopted by the Appraisal Standards Board of the Appraisal Foundation, all as
in effect on the date the Exhibit A-1 Loan was originated.

          50. Jurisdiction of Organization. Each Borrower under an Exhibit A-1
Loan was organized under the laws of the United States or the laws of a
jurisdiction located within the United States, its territories and possessions.

          51. Borrower Concentration. Except as otherwise specified on Schedule
C-51 hereto, no single Borrower or group of affiliated Borrowers is/are the
obligor(s) under any one or more Exhibit A-1 Loans with a Cut-off Date Principal
Balance of $50,000,000 or more.

          52. Escrows. All escrow deposits (including capital improvements and
environmental remediation reserves) relating to any Exhibit A-1 Loan that were
required to be delivered to the lender under the terms of the related Mortgage
Loan Documents, have been received and, to the extent of any remaining balances
of such escrow deposits, are in the possession or under the control of the
Seller or its agents (which shall include the Master Servicer). All such escrow
deposits which are required for the administration and servicing of such Exhibit
A-1 Loan are conveyed hereunder to the Purchaser.

          53. Access. The Mortgaged Property securing each Exhibit A-1 Loan is
located on or adjacent to a public road, or has access to an irrevocable
easement permitting ingress and egress.

          54. Thunderbird Airport Plaza Mortgage Loan. With respect to the
Exhibit A-1 Loan identified as Thunderbird Airport Plaza, upon termination of
the ground lease, the termination payment will, in all cases, be equal to, or
greater than, the sum of all amounts due

                                      C-19

<PAGE>

upon a related prepayment of the subject mortgage loan, including, without
limitation, principal, accrued interest and any yield maintenance fee,
prepayment premium, or other prepayment consideration required under the terms
of the loan documents.

          In the case of the mortgage loans identified as Thunderbird Airport
Plaza and Fairmount Place II, the Ground Lease provides that the ground landlord
will not terminate the Ground Lease without first giving notice to the lender of
its intent to terminate the Ground Lease and the expiration of cure periods
granted to the lender, but the Ground Lease does not provide that notices of
termination will not be effective against the lender without delivery of the
same to the lender.

In the case of the mortgage loan identified as Thunderbird Airport Plaza, the
Ground Lease will expire on March 31, 2043, after the exercise of all extension
options. The amortization term of the subject mortgage loan ends on January 11,
2033. In addition, the Ground Lease is subject to a termination option if the
ground lease premises are required for the future expansion and/or operation of
the surrounding airport or if the borrower is precluded from operating under the
terms of the ground lease because the federal government or other governmental
agency, such as the Federal Aviation Administration, assumes control of the
surrounding airport or because the ground landlord altered its development of
the surrounding airport. Upon the exercise of such termination option, a
termination payment will be payable to the borrower equal to the greater of (i)
the fair market value of the leasehold interest, considering the remaining lease
term and the fair market value of all improvements owned by the borrower or (ii)
the original construction cost of such improvements less three percent
depreciation per year.

                                SCHEDULE C-18(i)

In the case of the mortgage loan identified as Thunderbird Airport Plaza, the
Ground Lease provides that, with respect to a condemnation or taking, the ground
landlord will be entitled to that portion of the award made for or on account of
the taking or injury to the Mortgaged Property, taking account of the fact that
the Mortgaged Property is subject to the Ground Lease and of Landlord's
reversionary right, exclusive of improvements constructed by the borrower.

In the case of the mortgage loan identified as Fairmount Place II, the Ground
Lease provides that casualty or condemnation proceeds will be used by the
Landlord under the Ground Lease to restore the portion of the Mortgaged Property
subject to the Ground Lease. However, the lender does not have the right to hold
the proceeds for disbursement in connection with the repairs or to designate a
trustee to hold the proceeds. The Ground Lease covers 263 spaces in a parking
garage containing 488 parking spaces. The borrower will be entitled to a portion
of any condemnation award equal to the value of the borrower's leasehold
interest, and this award would be used for repairs or to pay down the debt in
accordance with the loan documents. Neither the borrower nor the lender has any
other interest in any condemnation award.

is subject to a termination option upon any of such events, and upon the
exercise of such termination option, a termination payment will be payable to
the borrower equal to the greater of (i) the fair market value of the leasehold
interest, considering the remaining lease term and the fair market value of all
improvements owned by the borrower or (ii) the original construction cost of
such improvements less three percent depreciation per year.

loan with an interest rate equal to 300 basis points over the 30 day LIBOR rate,
and it is subject to a subordination agreement executed by the holder of the
subject mortgage loan and the subordinate lender. In addition, the subordinate
lender may not take any enforcement action with respect to the subordinate loan
without the consent of the holder of the subject mortgage loan. The subordinate
lender is permitted to transfer the subordinate loan to one or more qualified
institutional lenders meeting certain criteria set forth in the subordination
agreement.

In the case of one (1) mortgage loan identified as BECO Building, a purchaser of
the property from the borrower, approved by the lender in accordance with the
loan documents and in connection with a related assumption of the subject
mortgage loan, would be permitted to incur mezzanine financing in an amount not
to exceed $4,000,000 in connection with such purchase. Such mezzanine loan would
be secured by ownership interests in the purchaser. The combined debt service
coverage ratio of the subject mortgage loan and the mezzanine loan must be at
least 1.20 to 1.00, and the combined loan-to-value ratio of the subject mortgage
loan and the mezzanine loan must not exceed 80%. The holder of the mezzanine
loan must execute an intercreditor agreement satisfactory to the holder of the
subject mortgage loan.

In the case of one (1) mortgage loan identified as Pine Meadow Apartments, a
$1,434,000 mezzanine loan is secured by membership interests in the borrower
held by the sole member of the borrower. An intercreditor agreement was executed
by the holder of the subject mortgage loan and the mezzanine lender, which
agreement provides that the mezzanine loan is subordinated in priority and
payment to the subject mortgage loan, that the mezzanine lender has cure rights
with respect to a borrower default and that the mezzanine lender may foreclose
on the ownership interests in borrower upon the satisfaction of certain
conditions. In addition, the mezzanine lender has an option to purchase the
subject mortgage loan if the subject mortgage loan is accelerated or if an
enforcement action is commenced thereunder. The purchase price will equal the
outstanding principal balance of the subject mortgage loan together with all
accrued interest and other amounts due thereon (including late charges, default
interest, exit fees, prepayment fees, yield maintenance, advances and
post-petition interest), any protective advances and any interest on such
advances, including all costs and expenses actually incurred by the holder of
the subject mortgage loan in enforcing the terms of the loan documents. Except
for certain transfers to transferees with approved characteristics, the
mezzanine lender may not transfer the mezzanine loan without the consent of the
holder of the subject mortgage loan. The mezzanine lender also has consent
rights with respect to certain actions to be taken with respect to the subject
mortgage loan.

In the case of the mortgage loan identified as The Ritz-Carlton, Key Biscayne,
the borrower is subject to litigation related to the foreclosure of construction
liens and related breach of contract actions. The dispute is presently in
arbitration. The title insurance company has provided insurance over the
recorded liens related to the dispute, and the principals of the borrower
delivered an indemnity agreement to the title insurance company. In addition,
$2,959,885 is being held by the title insurance company in escrow with respect
to the dispute. In the event of an adverse determination, the loan documents
require the borrower to either pay the amount of the determination within 60
days or to bond over the items and obtain removal of the claims as a lien on the
property. If the borrower fails to take either of these actions, the interest
rate on the subject mortgage loan will increase by four percent. In addition,
the non-recourse carveout guarantors of the subject mortgage loan have full
recourse liability for non-payment of any adverse determination amounts.

                                 SCHEDULE C-28A

In the case of the mortgage loan identified as Rocky Mount Marketplace, the
borrower may obtain the release of certain unimproved portions of the related
mortgaged real property without a partial defeasance or payment of a release
price upon satisfaction of various specified criteria, including evidence of
compliance with municipal and county requirements, the creation of a subdivision
plat depicting the release parcel as a separate subdivided lot such that the
release parcel and the remaining property will be separate tax parcels and the
recordation of any easements across the release parcel necessary to service the
remaining property.

                                 SCHEDULE C-28B

In the case of the multi-property loan portfolio identified as North Park
Executive Center, the related borrower can obtain the release of individual
properties from the related subject mortgage loan through a partial defeasance
of the subject mortgage loan in an amount equal to 110% of the allocated loan
amount and upon the satisfaction of certain legal and underwriting requirements.
In addition, the borrower may obtain a release of properties serving as
collateral for the subject mortgage loan in connection with one or more
assumptions of a portion of the subject mortgage loan. The transferee will
assume a portion of the loan equal to the outstanding principal balance of the
subject mortgage loan multiplied by the quotient of the allocated loan amount
for the subject property divided by the total allocated loan amount for all
properties. After the assumption, the released property will no longer serve as
collateral for the unassumed loan but will serve as collateral for the assumed
loan. The borrower and the transferee must satisfy the same conditions as would
be required for an assumption of the entire loan. In addition, (i) the debt
service coverage ratio must be at least 1.35 to 1.00 and (ii) the loan-to-value
ratio must not exceed 70%, in each case for both the assumed loan collateral and
the unassumed loan collateral. The borrower will be permitted to prepay a
portion of either the unassumed loan or the assumed loan, subject to a
prepayment fee, in order to satisfy the loan-to-value ratio test. Only a maximum
of two individual properties may be released through any combination of the
above release provisions.

In the case of the mortgage loan identified as Sully Place, the applicable
lock-out period for defeasance has expired. The subject mortgage loan is being
placed in its own loan REMIC and will be subject to a repurchase obligation of
the Seller in the event that the borrower exercises a defeasance option within
two years after the start-up date of the REMIC containing the other mortgage
loans.

In the case of the mortgage loan identified as Great Lakes Crossing, no
assumption fee will be due in connection with a transfer of the property and an
assumption of the loan. However, the borrower is required to reimburse the
holder of the subject mortgage loan for all reasonable expenses incurred by
Lender in connection with any transfer or sale. In addition, the borrower may
sell the property in connection with an assumption of the loan by entities with
certain pre-approved characteristics or to an entity otherwise approved by the
applicable rating agencies (each a "Permitted Owner"), so long as (a) unless the
transferee is affiliated with the borrower, a "no downgrade" letter is obtained
from each applicable rating agency and (b) a new non-consolidation opinion is
delivered. In addition, transfers of direct ownership interests in the borrower
are permitted so long as (a) after the transfer, either The Taubman Realty Group
Limited Partnership, a Delaware limited partnership ("TRG"), an affiliate of TRG
or a Permitted Owner controls the borrower and owns at least 50% of Borrower and
(b) if 49% or more of the direct or indirect ownership interests in the borrower
are being transferred to a person not owning at least 49% of the direct or
indirect ownership interests as of the origination of the subject mortgage loan,
the borrower must deliver a new non-consolidation opinion acceptable to the
rating agencies.

In the case of the mortgage loans identified as British Aerospace Systems and
Crescent at Carlyle, the assumption fee is 0.5%, rather than 1%.

In the case of the mortgage loan identified as Ritz-Carlton, Key Biscayne, the
assumption fee is 0.25%, rather than 1%.

In the case of the mortgage loans identified as Ford Factory Square, Paradise
Cay Apartments, and Northeast Medical Arts Center, the assumption fee is 0.5%,

wholly-owned by one or both of the non-recourse carveout guarantors. The
assumption fee will otherwise be 1%, except that in the case of the first
assumption of the subject mortgage loan, the assumption fee will be 0.5%.

subject mortgage loan is fully recourse to the two individual borrowers.

In the case of the mortgage loan identified as Great Lakes Crossing, the
non-recourse guarantor is not an individual (The Taubman Realty Group Limited
Partnership). In addition, the borrower and the non-recourse guarantor have
liability for intentional misrepresentation instead of material
misrepresentation. The subject mortgage loan also does not become recourse to
the borrower and the non-recourse guarantor in the event of a voluntary
bankruptcy.

In the case of the mortgage loans identified as British Aerospace Systems, The
Carl Zeiss Building, Crescent at Carlyle and Sully Place, there is no
non-recourse guarantor other than the borrower.

To the Parties Listed on Annex A hereto

          Re: Credit Suisse First Boston Mortgage Securities Corp.,
              Commercial Mortgage Pass-Through Certificates, Series 2003-CK2

Ladies and Gentlemen:

     I am a Vice President and Counsel of Credit Suisse First Boston LLC
("CSFB") and have acted as special counsel to Column Financial, Inc. (the
"Mortgage Loan Seller") in connection with certain matters relating to:

     (i) the Mortgage Loan Seller's sale to Credit Suisse First Boston Mortgage
Securities Corp. (the "Depositor") of certain multifamily and commercial
mortgage loans (the "Group I Mortgage Loans"), pursuant to that certain mortgage
loan purchase agreement (the "First Mortgage Loan Purchase Agreement"), dated as
of March 27, 2003, by and between the Depositor, as purchaser, and the Mortgage
Loan Seller, as seller,

     (ii) the Mortgage Loan Seller's sale to the Depositor of certain other
multifamily and commercial mortgage loans (the "Group II Mortgage Loans" and,
together with the Group I Mortgage Loans, the "Mortgage Loans"), pursuant to
that certain other mortgage loan purchase agreement (the "Second Mortgage Loan
Purchase Agreement" and, together with the First Mortgage Loan Purchase
Agreement, the "Mortgage Loan Purchase Agreements"), dated as of March 27, 2003,
by and among the Depositor, as purchaser, the Mortgage Loan Seller, as seller,
and KeyBank, as additional party, and

     (iii) the Mortgage Loan Seller's providing indemnities to the Depositor,
CSFB, Goldman, Sachs & Co. ("Goldman") and McDonald Investments Inc.
("McDonald"), pursuant to that certain indemnification agreement (the
"Indemnification Agreement"), dated March 27, 2003, by and among the Mortgage
Loan Seller, the Depositor, CSFB, Goldman and McDonald.

     Capitalized terms used and not otherwise defined herein have the meanings
given to them in the Mortgage Loan Purchase Agreements.

     In rendering the opinions set forth below, I have examined and relied upon
originals, copies or specimens, certified or otherwise identified to my
satisfaction, of the Indemnification Agreement and the Mortgage Loan Purchase
Agreements (collectively, the "Agreements"), and such certificates, corporate
records and other documents, agreements, instruments and opinions,

                                     D-2A-1

<PAGE>

as I have deemed appropriate as a basis for the opinions hereinafter expressed.
In connection with such examination, I have assumed the genuineness of all
signatures (other than with respect to the Mortgage Loan Seller), the
authenticity of all documents, agreements and instruments submitted to me as
originals, the conformity to original documents, agreements and instruments of
all documents, agreements and instruments submitted to me as copies or specimens
and the authenticity of the originals of such documents, agreements and
instruments submitted to me as copies or specimens and the accuracy of the
matters set forth in the documents, agreements and instruments I reviewed, to
the extent such matters do not constitute legal conclusions upon which I have
been asked to opine. As to any facts material to such opinions that were not
known to me, I have relied upon statements, certificates and representations of
officers and other representatives of the Depositor and the Mortgage Loan Seller
and of public officials.

     Based upon and subject to the foregoing, I am of the opinion that:

          1. The Mortgage Loan Seller is duly incorporated, validly existing and
     in good standing under the laws of the State of Delaware, with requisite
     power and authority to execute and deliver the Agreements and to perform
     its obligations thereunder.

          2. The execution, delivery and performance of the Agreements have been
     duly authorized by the Mortgage Loan Seller and the Agreements have been
     duly executed and delivered by the Mortgage Loan Seller.

          3. The execution and delivery by the Mortgage Loan Seller of the
     Agreements, the performance by the Mortgage Loan Seller of its obligations
     under the Agreements and the consummation by the Mortgage Loan Seller of
     the transactions therein contemplated, do not conflict with or result in a
     breach or violation of the Mortgage Loan Seller's organizational documents
     or, to my knowledge, conflict with or result in a breach or violation of
     any material indenture, agreement or instrument to which the Mortgage Loan
     Seller is a party or by which it or any of its property is bound, or any
     judgment, decree or order applicable to the Mortgage Loan Seller, of any
     New York State or federal court, regulatory body, administrative agency or
     other governmental authority, other than potential conflicts, breaches or
     violations which individually and in the aggregate are not reasonably
     expected to have a material adverse effect on the ability of the Mortgage
     Loan Seller to enter into and perform its obligations under the Agreements.

          4. To my knowledge, there is no legal or governmental action,
     investigation or proceeding pending or threatened against the Mortgage Loan
     Seller (a) asserting the invalidity of any of the Agreements, (b) seeking
     to prevent the consummation of any of the transactions contemplated by the
     Agreements or (c) which could reasonably be expected to materially and
     adversely affect the performance by the Mortgage Loan Seller of its
     obligations under, or the validity or enforceability (with respect to the
     Mortgage Loan Seller) of, the Agreements. For purposes of the opinion set
     forth in this paragraph, I have not regarded any legal or governmental
     actions, investigations or proceedings to be "threatened" unless the
     potential litigant or governmental authority has overtly threatened in
     writing to the Mortgage Loan Seller a present intention to initiate such
     proceedings.

          Re: Credit Suisse First Boston Mortgage Securities Corp.,
              Commercial Mortgage Pass-Through Certificates, Series 2003-CK2

Ladies and Gentlemen:

          We have acted as special counsel to Column Financial, Inc. ("Column")
with respect to certain matters in connection with the sale by Column, and the
purchase by Credit Suisse First Boston Mortgage Securities Corp. ("CSFBMSC"),
of: certain multifamily and commercial mortgage loans (collectively, the "Group
I Mortgage Loans"), pursuant to that certain mortgage loan purchase agreement
dated as of March 27, 2003 (the "First Mortgage Loan Purchase Agreement"),
between Column, as seller, and CSFBMSC, as purchaser; and certain other
multifamily and commercial mortgage loans (collectively, the "Group II Mortgage
Loans" and, collectively with the Group I Mortgage Loans, the "Mortgage Loans"),
pursuant to that certain other mortgage loan purchase agreement dated as of
March 27, 2003 (the "Second Mortgage Loan Purchase Agreement" and, together with
the First Mortgage Loan Purchase Agreement, the "Agreements"), among CSFBMSC, as
purchaser, Column, as seller, and KeyBank National Association, as additional
party.

          This opinion letter is being provided to you pursuant to Section
7(vii) of the First Mortgage Loan Purchase Agreement and Section 7(iii) of the
Second Mortgage Loan Purchase Agreement. Capitalized terms that are used, but
not defined, herein have the respective meanings set forth in, or otherwise
assigned to them pursuant to, the Agreements.

          For purposes of this opinion letter, we have reviewed the Agreements.
In addition, we have examined originals or copies, certified or otherwise
identified to our satisfaction, of such other documents and records as we have
deemed relevant or necessary as the basis for the opinions contained in this
letter; we have obtained such certificates from and made such inquiries of
officers and representatives of the parties to the Agreements and public
officials as we have deemed relevant or necessary as the basis for such
opinions; and we have relied upon, and assumed the accuracy of, such other
documents and records, such certificates and the statements made in response to
such inquiries, with respect to the factual matters upon which the opinions
contained herein are based.

                                     D-2B-1

<PAGE>

          In rendering this opinion letter, we have also assumed (i) the
truthfulness and accuracy of each of the representations and warranties as to
factual matters contained in the Agreements, (ii) the legal capacity of natural
persons, (iii) the genuineness of all signatures, (iv) the authenticity of all
documents submitted to us as originals, (v) the conformity to authentic
originals of all documents submitted to us as certified, conformed or
photostatic copies, (vi) the due organization of each of the parties to the
Agreements and the valid existence of each such party in good standing under the
laws of its jurisdiction of organization, (vii) except to the extent expressly
addressed by our opinions below, the power and authority of the parties to each
of the Agreements to enter into, perform under and consummate the transactions
contemplated by such Agreement, without any resulting conflict with or violation
of the organizational documents of any such party or with or of any law, rule,
regulation, order, writ or decree applicable to any such party or its assets,
and without any resulting default under or breach of any other agreement or
instrument by which any such party is bound or which is applicable to it or its
assets, (viii) the due authorization by all necessary action, and the due
execution and delivery, of each of the Agreements by all parties thereto, (ix)
except to the extent expressly addressed by our opinions below, the constitution
of each of the Agreements as the legal, valid and binding obligation of each
party thereto, enforceable against such party in accordance with its terms, and
(x) the absence of any other agreement that supplements or otherwise modifies
the intentions and agreements of the parties to the Agreements, as expressed
therein.

          Our opinions set forth below with respect to the enforceability of any
agreement or any particular right or obligation under any agreement are subject
to: (1) general principles of equity, including concepts of materiality,
reasonableness, good faith and fair dealing and the doctrine of estoppel; (2)
the possible unavailability of specific performance and injunctive relief,
regardless of whether considered in a proceeding in equity or at law; (3) the
effect of certain laws, rules, regulations and judicial and other decisions upon
the enforceability of (a) any provision that purports to waive (i) the
application of any federal, state or local statute, rule or regulation, (ii) the
application of any general principles of equity or (iii) the obligation of
diligence, (b) any provision that purports to grant any remedies that would not
otherwise be available at law, to restrict access to any particular legal or
equitable remedies, to make any rights or remedies cumulative and enforceable in
addition to any other right or remedy, to provide that the election of any
particular remedy does not preclude recourse to one or more other remedies, to
provide that the failure to exercise or the delay in exercising rights or
remedies will not operate as a waiver of such rights or remedies, to impose
penalties or forfeitures, or to provide for set-off in the absence of mutuality
between the parties, (c) any provision that purports to release, exculpate or
exempt a party from, or indemnify a party for, liability for any act or omission
on its part that constitutes negligence, recklessness or willful or unlawful
conduct, (d) any provision that purports to govern matters of civil procedure,
including any such provision that purports to establish evidentiary standards,
to waive objections to venue or forum, to confer subject matter jurisdiction on
any court that would not otherwise have such jurisdiction or to waive any right
to a jury trial, or (e) any provision that purports to render unenforceable any
modification, waiver or amendment that is not executed in writing, to sever any
provision of any agreement, to appoint any person or entity as the
attorney-in-fact of any other person or entity or to provide that any agreement
or any particular provision thereof is to be governed by or construed in
accordance with the laws of any jurisdiction other than the State of New York;
(4) bankruptcy, insolvency, receivership, reorganization, liquidation, voidable
preference,

                                     D-2B-2

<PAGE>

fraudulent conveyance and transfer, moratorium and other similar laws affecting
the rights of creditors or secured parties generally; and (5) public policy
considerations underlying the securities laws, to the extent that such public
policy considerations limit the enforceability of any provision of any agreement
that purports or is construed to provide indemnification with respect to
securities law violations.

          In rendering this opinion letter, we do not express any opinion
concerning the laws of any jurisdiction other than the laws of the State of New
York and, where expressly referred to below, the federal laws of the United
States of America (without regard to conflicts of law principles). In addition,
we do not express any opinion with respect to (i) the tax, securities or "doing
business" laws of any particular jurisdiction, including, without limitation,
the State of New York, or (ii) any law, rule or regulation to which Column may
be subject as a result of any other person's or entity's legal or regulatory
status or any such other person's or entity's involvement in the transactions
contemplated by the Agreements. Furthermore, we do not express any opinion with
respect to any matter not expressly addressed below.

          Based upon and subject to the foregoing, we are of the opinion that:

          1. Each of the Agreements constitutes a valid, legal and binding
     agreement of Column, enforceable against Column in accordance with its
     terms.

          2. No consent, approval, authorization or order of any federal or
     State of New York court or governmental agency or body is required for the
     consummation by Column of the transactions contemplated by the Agreements,
     except for those consents, approvals, authorizations or orders that
     previously have been obtained.

          3. Column's execution, delivery and performance of the Agreements will
     not in any material respect conflict with or result in a material violation
     of any federal or State of New York statute or regulation of general
     applicability in transactions of the type contemplated by the Agreements.

          The opinions expressed herein are being delivered to you as of the
date hereof, and we assume no obligation to advise you of any changes of law or
fact that may occur after the date hereof, notwithstanding that such changes may
affect the legal analysis or conclusions contained herein. This opinion letter
is solely for your benefit in connection with the closing of Column's sale of
the Mortgage Loans to CSFBMSC, pursuant to the Agreements, and may not be relied
on in any manner for any other purpose or by any other person or transmitted to
any other person without our prior consent.

                                                 Very truly yours,

                                     D-2B-3

         purposes of registering under the Securities Act of 1933, as amended
         (the "Securities Act"), certain offerings of mortgage pass-through

<PAGE>

                           (v) the  transfer of the  Mortgage Loans by the

         Credit Suisse First Boston LLC ("CSFB LLC"), Goldman, Sachs & Co.

Mortgage Loans were originated by KeyBank and subsequently sold by KeyBank to
Column. The Group I Mortgage Loans that are not KeyBank Mortgage Loans
constitute the "Column Mortgage Loans".

                  For the purposes of this letter, we have reviewed: the
Agreements; the Registration Statement; the Prospectus, dated March 27, 2003,
relating to publicly offered mortgage pass-through certificates evidencing
interests in trust funds established by the Depositor (the "Basic Prospectus");
and the Prospectus Supplement, dated March 27, 2003, specifically relating to
the Trust and the Publicly Offered Certificates (the "Prospectus Supplement",
and, together with the Basic Prospectus, the "Prospectus"). In addition, we have
examined originals or copies, certified or otherwise identified to our
satisfaction, of such other documents and records as we have deemed relevant or
necessary as the basis for rendering this letter; we have obtained such
certificates from and made such inquiries of officers and representatives of the
parties to the Agreements and public officials as we have deemed relevant or
necessary as the basis for rendering this letter; and we have relied upon, and
assumed the accuracy of, such other documents and records, such certificates and
the statements made in response to such inquiries, with respect to the factual
matters upon which the statements made in this letter are based. We have also
assumed (i) the truthfulness and accuracy of each of the representations and
warranties as to factual matters contained in the Agreements, (ii) the legal
capacity of natural persons, (iii) the genuineness of all signatures, (iv) the
authenticity of all documents submitted to us as originals, (v) the conformity
to authentic originals of all documents submitted to us as certified, conformed
or photostatic copies, (vi) the due organization of all parties to each of the
Agreements and the valid existence of each such party in good standing under the
laws of its jurisdiction of organization, (vii) the due authorization by all
necessary action, and the due execution and delivery, of each of the Agreements
by all parties thereto, (viii) the constitution of each of the Agreements as the
legal, valid and binding obligation of each party thereto, enforceable against
such party in accordance with its terms, (ix) compliance with

                                     D-2C-2
<PAGE>

the respective Agreements by the parties thereto, (x) the conformity, to the
requirements of the respective Mortgage Loan Purchase Agreements and the Pooling
and Servicing Agreement, of the Mortgage Notes, the Mortgages and the other
documents delivered to the Trustee by, on behalf of, or at the direction of, the
Depositor, Column and KeyBank, (xi) the conformity of the text of each document
filed with the Commission through the Commission's Electronic Data Gathering,
Analysis and Retrieval System to the printed documents reviewed by us, and (xii)
the absence of any other agreement that supplements or otherwise modifies the
intentions and agreements of the parties to the Agreements, as expressed
therein. In making the statements set forth below, we do not express any view
concerning the laws of any jurisdiction other than the federal laws of the
United States of America.

                  We are delivering this letter in our capacity as special
counsel to the Depositor and Column. In the course of our acting in such
capacity, we have generally reviewed and discussed with certain representatives
of the Depositor, Column, the Underwriters and the other parties to the
Agreements and their respective counsel (in addition to us) the information set
forth in the Registration Statement and the Prospectus, other than any documents
or information included therein solely by incorporation by reference (all such
documents and information so incorporated by reference shall be referred to
herein as the "Excluded Information"), and we have reviewed certain loan
summaries prepared by Column or an affiliate of Column, or a counsel for either
of them, in respect of the Column Mortgage Loans. While we have made no
independent check or verification of, and do not assume any responsibility for,
the accuracy, completeness or fairness of the statements contained in the
Registration Statement or the Prospectus, on the basis of the foregoing, nothing
has come to our attention that has caused us to believe that (a) the
Registration Statement (exclusive of the Excluded Information therein, as to
which we express no view or belief), as of its effective date, contained an
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading
or (b) the Prospectus (exclusive of the Excluded Information therein, as to
which we express no view or belief), as of the date of the Prospectus Supplement
or as of the date hereof, contained or contains any untrue statement of a
material fact or omitted or omits to state any material fact necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, except that we express no view or belief as to (x) any
financial statements, schedules and/or other numerical, financial or statistical
data set forth or referred to therein or omitted therefrom, (y) any information
contained in or omitted from the Prospectus regarding the nature and
characteristics of the KeyBank Mortgage Loans and/or the Borrowers and Mortgaged
Properties relating to such Mortgage Loans or (z) any information contained in
or omitted from the computer diskette that accompanies the Prospectus. In that
connection, we advise you that we have relied, to the extent that we may
properly do so in the discharge of our professional responsibilities as
experienced securities law practitioners, upon the judgment and statements of
officers and representatives of the Depositor and Column in connection with the
determination of materiality.

                  When used in this letter, the term "attention" or words of
similar import mean the conscious awareness of facts or other information of the
Sidley Austin Brown & Wood LLP attorneys currently practicing law with this firm
who have been involved in any material respect in representing the Depositor
and/or Column in connection with the Transactions or who may have represented
Column in the origination of any of the Mortgage Loans. We call to your
attention that, with your knowledge and consent, except as described above, such

Brown & Wood LLP attorneys have not examined or otherwise reviewed any of the
Mortgage Files, any particular documents contained in such files or any other
documents with respect to the Mortgage Loans for purposes of delivering this
letter.

and we assume no obligation to advise you of any changes of law or fact that may
occur after the date hereof, notwithstanding that such changes may affect the
statements made herein. This letter is solely for your benefit in connection
with the Transactions and may not be relied on in any manner for any other
