mortgage investment conduit" (a "REMIC").

            As provided herein, the Trustee will elect to treat the segregated

Certificates.

            As further provided herein, the Trustee will elect to treat the
segregated pool of assets consisting of the Uncertificated Lower-Tier Interests
and certain other related assets subject to this Agreement as a REMIC for

Interest and the Post-ARD Additional Interest Distribution Account shall be
treated as a grantor trust under subpart E, Part I of subchapter J of the Code.
The Class V Certificates will represent undivided beneficial interests in the
portion of the Trust Fund consisting of the Post-ARD Additional Interest and the
Post-ARD Additional Interest Distribution Account. Additionally, the Trust Fund
shall not include any B Loan, any interest of the holders of any B Loan or any

      reasonably acceptable to the applicable Special Servicer, for such longer
      period (not to exceed 150 days past the Due Date for such Balloon Payment)
      during which such refinancing would occur);

            (iii) the passage of 60 days after the applicable Special Servicer
      receives notice that the Borrower under such Mortgage Loan has become the
      subject of bankruptcy, insolvency or similar proceedings, which
      proceedings remain undischarged and undismissed at the end of such 60-day
      period;

            (iv) the passage of 60 days after the applicable Special Servicer
      receives notice that a receiver or similar official has been appointed
      with respect to the related Mortgaged Property (provided that such
      receiver or similar official continues in that capacity at the end of such
      60-day period); or

            (v) the related Mortgaged Property becomes an REO Property.

            "Appraised Value" shall mean, (a) with respect to each Mortgaged
Property or REO Property (other than a residential cooperative property), the
appraised value thereof (as is) based upon the most recent Appraisal obtained or
conducted, as appropriate, pursuant to this Agreement and (b) with respect to

applicable, any related REO Property, the value of such property as shown in the

rental apartment building).

paid in full on or prior to its Anticipated Repayment Date.

            "Assumed Monthly Payment" shall mean:

            (a) with respect to any Balloon Mortgage Loan delinquent in respect
      of its Balloon Payment beyond the Determination Date immediately following
      its scheduled maturity date (as such date may be extended in connection
      with a bankruptcy, insolvency or similar proceeding involving the related
      Borrower or by reason of a modification, waiver or amendment granted or
      agreed to by the applicable Master Servicer or the applicable Special
      Servicer pursuant to Section 3.20), for that scheduled maturity date and
      for each subsequent Due Date as of which such Mortgage Loan remains
      outstanding and part of the Trust Fund, the scheduled monthly payment of
      principal and/or interest deemed to be due with respect to such Mortgage
      Loan on such Due Date equal to the amount that would have been due in
      respect thereof on such Due Date (other than any Default Interest) if such
      Mortgage Loan had been required to continue to accrue interest in
      accordance with its terms, and to pay principal in accordance with the
      amortization schedule (if any), in effect immediately prior to, and
      without regard to the occurrence of, such maturity date; and

            (b) with respect to any REO Mortgage Loan, for any Due Date as of
      which the related REO Property remains part of the Trust Fund, the
      scheduled monthly payment of principal and/or interest deemed to be due in
      respect thereof on such Due Date equal to the Monthly Payment (or, in the

express provisions of the related Mortgage Loan Documents and, in the absence of
such express provisions or if and to the extent that such terms authorize the
lender to use its discretion, shall be applied: first, as a recovery of any
related and unreimbursed Servicing Advances, if applicable, unpaid Liquidation
Expenses and, to the extent not covered by Liquidation Expenses, Additional
Trust Fund Expenses and other fees and expenses payable to any Master Servicer,
any Special Servicer or the Trustee and attributable to such Mortgage Loan;
second, as a recovery of accrued and unpaid interest on such Mortgage 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 related Due Date),
exclusive, however, of any portion of such accrued and unpaid interest that
constitutes Default Interest or, in the case of an ARD Mortgage Loan after its
Anticipated Repayment Date, that constitutes Post-ARD Additional Interest;
third, as a recovery of principal of such Mortgage Loan then due and owing,
including by reason of acceleration of the Mortgage Loan following a default
thereunder (or, if a Liquidation Event has occurred in respect of such Mortgage
Loan, as a recovery of principal to the extent of its entire remaining unpaid
principal balance); fourth, unless a Liquidation Event has occurred in respect
of such Mortgage Loan, as a recovery of amounts to be currently applied to the
payment of, or escrowed for the future payment of, real estate taxes,
assessments, insurance premiums, ground rents (if applicable) and similar items;
fifth, unless a Liquidation Event has occurred in respect of such Mortgage Loan,
as a recovery of Reserve Funds to the extent then required to be held in escrow;
sixth, as a recovery of any Prepayment Premium or Yield Maintenance Charge then
due and owing under such Mortgage Loan; seventh, as a recovery of any Default
Charges then due and owing under such Mortgage Loan; eighth, as a recovery of
any assumption fees and modification fees then due and owing under such Mortgage
Loan; ninth, as a recovery of any other amounts then due and owing under such
Mortgage Loan other than remaining unpaid principal and, in the case of an ARD
Mortgage Loan after its Anticipated Repayment Date, other than Post-ARD
Additional Interest; tenth, as a recovery of any remaining principal of such
Mortgage Loan to the extent of its entire remaining unpaid principal balance;
and, eleventh, in the case of an ARD Mortgage Loan after its Anticipated
Repayment Date, as a recovery of accrued and unpaid Post-ARD Additional Interest
on such ARD Mortgage Loan to but not including the date of receipt by or on
behalf of the Trust.

            (b) Collections by or on behalf of the Trust in respect of each REO
Property (exclusive of amounts to be applied to the payment of the costs of
operating, managing, maintaining and disposing of such REO Property) shall be
treated: first, as a recovery of any related and unreimbursed Servicing Advances
and, if applicable, unpaid Liquidation Expenses and, to the extent not covered
by Liquidation Expenses, Additional Trust Fund Expenses or other fees and
expenses payable to any Master Servicer, any Special Servicer or the Trustee and
attributable to such REO Property or the related REO Mortgage Loan; second, as a
recovery of accrued and unpaid interest on the related REO Mortgage Loan to, but
not including, the Due Date in the Collection Period of receipt, by or on behalf
of the Trust exclusive, however, of any portion of such accrued and unpaid
interest that constitutes Default Interest or, in the case of an REO Mortgage
Loan that relates to an ARD Mortgage Loan after its Anticipated Repayment Date,
that constitutes Post-ARD Additional Interest; third, as a recovery of principal
of the related REO Mortgage 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 REO Mortgage Loan;
fifth, as a recovery of any Default Charges deemed to be due and owing in
respect of the related REO Mortgage Loan; sixth, as a recovery of any other
amounts deemed to be due and owing in respect of the related REO Mortgage Loan
(other than, in the case of an REO Mortgage Loan that relates to an ARD Mortgage
Loan after its Anticipated Repayment Date, accrued and unpaid Post-ARD
Additional Interest); and seventh, in the case of an REO Mortgage Loan that
relates to an ARD Mortgage Loan after its Anticipated Repayment Date, as a
recovery of any accrued and unpaid Post-ARD Additional Interest on such REO
Mortgage Loan to but not including the date of receipt by or on behalf of the
Trust.

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

            (d) Insofar as amounts received in respect of any Mortgage Loan or
REO Property and allocable to shared fees and shared charges owing in respect of
such Mortgage Loan or the related REO Mortgage Loan, as the case may be, that
constitute Additional Master Servicing Compensation payable to the applicable
Master Servicer and/or Additional Special Servicing Compensation payable to the
applicable 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 applicable Master Servicer, on the one hand, and
such of those fees and charges as are payable to the applicable 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 applicable Master
Servicer and reflected in the appropriate monthly report from such Master
Servicer and in the appropriate monthly Statement to Certificateholders as
provided in Section 4.02.

            (f) In the case of each Mortgaged Property that is a residential
cooperative property, the respective files and reports comprising the CMSA
Investor Reporting Package (other than the CMSA Servicer Watch List) shall
present the Projected Net Cash Flow for such Mortgaged Property and the
Projected Debt Service Coverage Ratio for the related Co-op Mortgage Loan, as
such terms apply to residential cooperative properties, if and to the extent
that such file or report requires preparation and/or submission of data
concerning net cash flow or debt service coverage.

            Section 1.04  Cross-Collateralized Mortgage Loans

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

                                   ARTICLE II

                CONVEYANCE OF MORTGAGE LOANS; REPRESENTATIONS AND
           WARRANTIES; ORIGINAL ISSUANCE OF UNCERTIFICATED LOWER-TIER
                      INTERESTS; EXECUTION OF CERTIFICATES


            Section 2.01 Conveyance of 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-CPN1." Wells Fargo is hereby
appointed, and does hereby agree, to act as Trustee hereunder and, in such
capacity, to hold the Trust Fund in trust for the exclusive use and benefit of
all present and future Certificateholders. It is not intended that this
Agreement create a partnership or a joint-stock association.

            (b) The Depositor, concurrently with the execution and delivery
hereof, does hereby sell, assign, transfer and otherwise convey to the Trustee
without recourse for the benefit of the Certificateholders, all the right, title
and interest of the Depositor in, to and under (i) the Original Mortgage Loans,
all payments under and proceeds of such Mortgage Loans received after the
Closing Date (other than scheduled payments of interest and principal due on or
before the respective Due Dates for the Original Mortgage Loans in March 2003),
and all documents included in the related Mortgage Files and Servicing Files and
any related Additional Collateral; (ii) any REO Property acquired in respect of
any such Mortgage Loan; (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 and, if established,
the REO Account, 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 Mortgage
Loans pursuant to the Designated Sub-Servicer Agreements.

            Upon the sale of Certificates representing at least 10% of the
aggregate Certificate Principal Balance of all the Certificates to parties that
are not Affiliates of the Depositor, the Depositor shall, under GAAP, report:
(i) its acquisition of the Original Column Mortgage Loans from Column, pursuant
to the Column Mortgage Loan Purchase Agreement, as a purchase of such Mortgage
Loans from Column; (ii) its acquisition of the Original PNC Mortgage Loans from
PNC, pursuant to the PNC Mortgage Loan Purchase Agreement, as a purchase of such
Mortgage Loans from PNC; (iii) its acquisition of the Original NCCB Mortgage
Loans, pursuant to the NCCB Mortgage Loan Purchase Agreement, as a purchase of
such Mortgage Loans from NCCB; (iv) its acquisition of the Original NCBFSB
Mortgage Loans from NCBFSB, pursuant to the NCBFSB Mortgage Loan Purchase
Agreement, as a purchase of such Mortgage Loans from NCBFSB; and (v) its
transfer of the Original Mortgage Loans to the Trustee, pursuant to this Section
2.01(b), as a sale of such Mortgage Loans to the Trustee. In connection with the
foregoing, upon the sale of Certificates representing at least 10% of the
aggregate Certificate Principal Balance of all the Certificates to parties that
are not Affiliates of the Depositor, 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).

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

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

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

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

            (e) As soon as reasonably possible, and in any event within 60 days
after the later of (i) the Closing Date (or, in the case of a Replacement
Mortgage Loan substituted as contemplated by Section 2.03, after the related
date of substitution) and (ii) the date on which all recording information
necessary to complete the subject document is received by the Trustee, the
Trustee shall complete (to the extent necessary), and shall submit for recording
or filing, as the case may be, including via electronic means, if appropriate,
in or with the appropriate office for real property records or UCC Financing
Statements, as applicable, each assignment of Mortgage and assignment of
Assignment of Leases in favor of the Trustee referred to in clauses (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-2 or UCC-3 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-2 or UCC-3
assignment shall reflect that the filed copy thereof or an appropriate receipt
therefor, as applicable, should be returned to the Trustee following filing;
provided that in those instances where the public recording office retains the
original assignment of Mortgage or assignment of Assignment of Leases the
Trustee shall obtain therefrom a copy of the recorded original. At such time as
such assignments, UCC-2s, UCC-3s or verifications of electronic filing have been
returned to the Trustee, the Trustee shall forward a copy thereof to the
applicable Master Servicer. If any such document or instrument is lost or
returned unrecorded or unfiled, as the case may be, because of a defect therein,
the Trustee shall direct the related Mortgage Loan Seller to prepare or cause to
be prepared promptly, pursuant to the related Mortgage Loan Purchase Agreement,
a substitute therefor or cure such defect, as the case may be, and thereafter
the Trustee shall, upon receipt thereof, cause the same to be duly recorded or
filed, as appropriate. If any Mortgage Loan Seller has been so notified and has
not prepared a substitute document or cured such defect, as the case may be,
within 45 days, the Trustee shall promptly notify the applicable Master
Servicer, the applicable Special Servicer, the Rating Agencies and the
Controlling Class Representative. Each Mortgage Loan Seller shall be responsible
for paying the reasonable fees and out-of-pocket expenses of the Trustee in
connection with the above-referenced recording and filing of documents insofar
as it relates to the Original Mortgage Loans acquired by the Depositor from such
Mortgage Loan Seller, all as more particularly provided for in the related
Mortgage Loan Purchase Agreement.

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

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

            (g) Also in connection with the Depositor's assignment pursuant to
Section 2.01(b) above, the Depositor shall deliver to and deposit with, or cause
to be delivered to and deposited with, the applicable Master Servicer, on or
before the Closing Date, the original or a copy of any Group Environmental
Insurance Policy (and, if not included in the Servicing File for the subject
Mortgage Loan, any other Environmental Insurance Policy) acquired by the
Depositor or an Affiliate of the Depositor.

            Section 2.02  Acceptance of Mortgage Assets by Trustee

            (a) Subject to the other provisions in this Section 2.02, the
Trustee, by its execution and delivery of this Agreement, hereby accepts receipt
on behalf of the Trust, directly or through a Custodian on its behalf, of (i)
the Original Mortgage Loans and all documents delivered to it that constitute
portions of the related Mortgage Files and (ii) all other assets delivered to it
and included in the Trust Fund, in good faith and without notice of any adverse
claim, and declares that it or a Custodian on its behalf holds and will hold
such documents and any other documents received by it that constitute portions
of the Mortgage Files, and that it holds and will hold the Original Mortgage
Loans and such other assets, together with any other Mortgage Loans and assets
subsequently delivered to it that are to be included in the Trust Fund, in trust
for the exclusive use and benefit of all present and future Certificateholders.
The Trustee (acting through the applicable Master Servicer) shall hold any
Letter of Credit in a custodial capacity only and shall have no obligation to
maintain, extend the term of, enforce or otherwise pursue any rights under such
Letter of Credit. In connection with the foregoing, the Trustee hereby certifies
to each of the other parties hereto and the Mortgage Loan Sellers that, as to
each Original Mortgage Loan, except as to any LOC Cash Reserve and except as
specifically identified in the Schedule of Exceptions to Mortgage File Delivery
attached hereto as Exhibit B-2, (i) the Specially Designated Mortgage Loan
Documents 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 Mortgage Loan; provided that with respect to any Letters of
Credit, the Trustee's certification shall be based upon copies of the Letters of
Credit (including related amendment, assignment and transfer documents)
delivered to the Trustee or its Custodian. To the extent that the contents of
the Mortgage File for any A Loan relate to the corresponding B Loan, the Trustee
will also hold such Mortgage File in trust for the benefit of the holder of the
related B 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, if such state
level UCC Financing Statement was not filed on the national form, one local UCC
Financing Statement filing in the county of each 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" will be delivered in form suitable for filing and
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 60th 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, and (ii) the date on
which all the affected Mortgage Loans are removed from the Trust Fund), the
Trustee or a Custodian on its behalf shall review the documents delivered to it
or such Custodian with respect to each Original Mortgage Loan, and the Trustee
shall, subject to Sections 1.04, 2.02(c) and 2.02(d), certify in writing
(substantially in the form of Exhibit B-3) to each of the other parties hereto,
the Mortgage Loan Sellers and the Controlling Class Representative that, as to
each Original Mortgage Loan then subject to this Agreement (except as to any LOC
Cash Reserve and except as specifically identified in any exception report
annexed to such certification): (i) the original Mortgage Note specified in
clause (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 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 Mortgage Loan have been reviewed by it or by such
Custodian on its behalf and (A) appear regular on their face (handwritten
additions, changes or corrections shall not constitute irregularities if
initialed by the Borrower), (B) appear to have been executed and (C) purport to
relate to such Mortgage Loan.

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

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

            (d) In performing the reviews contemplated by subsections (a) and
(b) above, the Trustee may conclusively rely on the related Mortgage Loan Seller
as to the purported genuineness of any such document and any signature thereon.
It is understood that the scope of the Trustee's review of the Mortgage Files is
limited solely to confirming that the documents specified in clauses (i) through
(v), clause (vii) and, in the case of any 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 Mortgage
                          Loans by the Mortgage Loan Sellers 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 Mortgage
Loan, then such party shall give prompt written notice thereof to the other
parties hereto, including (unless it is the party that discovered the Document
Defect or Breach) the Trustee. Upon the Trustee's discovery or receipt of notice
that a Document Defect or Breach exists with respect to any Mortgage Loan, the
Trustee shall notify the Controlling Class Representative, the Depositor, the
related Mortgage Loan Seller and the Column Performance Guarantor (if a Column
Mortgage Loan is involved).

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

            (b) Promptly upon its becoming aware of any Material Document Defect
or Material Breach with respect to any Mortgage Loan, the applicable Master
Servicer shall (and the applicable Special Servicer may) notify the related
Mortgage Loan Seller and, if the affected Mortgage Loan is a Column Mortgage
Loan, the Column Performance Guarantor, in writing of such Material Document
Defect or Material Breach, as the case may be, and direct the related Mortgage
Loan Seller and, if the affected Mortgage Loan is a Column Mortgage Loan, the
Column Performance Guarantor, 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 with
respect to any Mortgage Loan, 15 days) from the receipt by the related Mortgage
Loan Seller and, if the affected Mortgage Loan is a Column Mortgage Loan, the
Column Performance Guarantor, of such notice (or any earlier discovery by the
related Mortgage Loan Seller of the subject Material Document Defect or Material
Breach, as the case may be) (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(d) below, repurchase the affected Mortgage Loan
(as, if and to the extent required by the related Mortgage Loan Purchase
Agreement or the Column Performance Guarantee, as applicable), at the applicable
Purchase Price; provided that if the related Mortgage Loan Seller or,
alternatively, if the affected Mortgage Loan is a Column Mortgage Loan, the
Column Performance Guarantor, certifies to the Trustee in writing (i) that such
Material Document Defect or Material Breach, as the case may be, does not relate
to whether the affected Mortgage Loan is or, as of the Closing Date, 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 the related Mortgage Loan Seller or, alternatively, if the affected
Mortgage Loan is a Column Mortgage Loan, the Column Performance Guarantor, 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 the related Mortgage Loan Seller or,
alternatively, if the affected Mortgage Loan is a Column Mortgage Loan, the
Column Performance Guarantor, is pursuing in connection with the cure of such
Material Document Defect or Material Breach, as the case may be, and (v) that
the related Mortgage Loan Seller or, alternatively, if the affected Mortgage
Loan is a Column Mortgage Loan, the Column Performance Guarantor, anticipates
that such Material Document Defect or Material Breach, as the case may be, will
be cured within an additional period equal to any such applicable Resolution
Extension Period (a copy of which certification shall be delivered by the
Trustee to the applicable Master Servicer, the applicable Special Servicer and
the Controlling Class Representative), then the related Mortgage Loan Seller
and, if the affected Mortgage Loan is a Column Mortgage Loan, the Column
Performance Guarantor, shall have an additional period equal to any such
applicable Resolution Extension Period to complete such correction or cure (or,
upon failure to complete such correction or cure, to repurchase the affected
Mortgage Loan); and provided, further, that, in lieu of effecting any such
repurchase (but, in any event, no later than such repurchase would have to have
been completed), the related Mortgage Loan Seller and, if the affected Mortgage
Loan is a Column Mortgage Loan, the Column Performance Guarantor, 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 Mortgage Loan is
a "defective obligation" within the meaning of Section 860G(a)(4)(B)(ii) of the
Code and Treasury Regulations Section 1.860G-2(f)), to replace the affected
Mortgage Loan with one or more Qualifying Substitute Mortgage Loans and to pay a
cash amount equal to the applicable Substitution Shortfall Amount, subject to
any other applicable terms and conditions of the related Mortgage Loan Purchase
Agreement or the Column Performance Guarantee, as applicable, and this
Agreement. If any Mortgage Loan is to be repurchased or replaced as contemplated
by this Section 2.03, the applicable Master Servicer shall designate its
Collection Account as the account to which funds in the amount of the applicable
Purchase Price or Substitution Shortfall Amount (as the case may be) are to be
wired, and such Master Servicer shall promptly notify the Trustee when such
deposit is made. Any such repurchase or replacement of a Mortgage Loan shall be
on a whole loan, servicing released basis.

            Notwithstanding the foregoing, if there exists a Breach of any
representation or warranty on the part of a Mortgage Loan Seller set forth in,
or made pursuant to, Section 4(b) or 4(d) of the related Mortgage Loan Purchase
Agreement that the Mortgage Loan Documents or any particular Mortgage Loan
Document 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 applicable Master Servicer shall (and the applicable Special Servicer may)
direct the related Mortgage Loan Seller in writing to wire transfer to the
Collection Account, within 90 days of such Mortgage Loan Seller's receipt of
such direction, the amount of any such costs and expenses borne by the Trust
that are the basis of such Breach and have not been reimbursed by the related
Borrower; provided, however, that in the event any such costs and expenses
exceed $10,000, the related Mortgage Loan Seller shall have the option to
repurchase such Mortgage Loan at the applicable Purchase Price, substitute for
such Mortgage Loan (subject to the criteria for substitution) and pay the
applicable Substitution Shortfall Amount or pay such costs and expenses. Except
as provided in the proviso to the immediately preceding sentence, the related
Mortgage Loan Seller shall remit the amount of such costs and expenses and upon
its making such deposit, the related Mortgage Loan Seller shall be deemed to
have cured such Breach in all respects. Provided such payment is made, 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 neither the related Mortgage Loan Seller nor,
if the affected Mortgage Loan is a Column Mortgage Loan, the Column Performance
Guarantor, shall be obligated to repurchase or otherwise cure such Breach 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 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 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
      related Mortgage Loan Seller's receipt of written notice from the Trustee,
      the applicable Master Servicer or the applicable Special Servicer 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 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 related Mortgage
      Loan Seller's receipt of written notice from the Trustee, the applicable
      Master Servicer or the applicable Special Servicer 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 Mortgage Loan as
      of the commencement of the applicable Initial Resolution Period, zero
      (-0-) days, except that, if the related Mortgage Loan Seller did not
      receive written notice from the Trustee, the applicable Master Servicer or
      the applicable 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 involving a Specially Designated Mortgage Loan Document for any Mortgage
Loan; and provided, further, that if a Material Document Defect exists with
respect to any Mortgage Loan, and if the related Mortgage Loan Seller or the
Column Performance Guarantor, as the case may be, escrows with the applicable
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
applicable 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 amount 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 Mortgage Loan, and if
the applicable 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,
the 30th day following the related Mortgage Loan Seller's receipt of written
notice from the applicable Special Servicer of the occurrence of the related
Servicing Transfer Event and of such determination; 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 with respect
to a Mortgage Loan, and if the related Mortgage Loan Seller or the Column
Performance Guarantor, as the case may be, delivers to the applicable 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 applicable Master Servicer 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, 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 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
Mortgage Loan, to cover any Realized Loss related thereto; and (iii) if the
related Mortgage Loan Seller (or, if it is the party that delivered the subject
Purchase Price Security Deposit, the Column Performance Guarantor) 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 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 Defect is not remedied on or before the second
anniversary of the Closing Date, or if such Mortgage Loan becomes a Specially
Serviced Mortgage Loan and the applicable 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 the related Mortgage Loan Seller has
received 30 days' prior written notice from the applicable Special Servicer of
the occurrence of the related Servicing Transfer Event and of such
determination, to apply the Purchase Price Security Deposit to a full or
partial, as applicable, payment of the Purchase Price for such Mortgage Loan.
Any amounts withdrawn by the applicable Master Servicer from the Purchase Price
Security Deposit Account for any Mortgage Loan shall be deposited by the
applicable Master Servicer into its 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 (a) be part of the Trust Fund but outside either Trust REMIC or
the Grantor Trust and (b) be an "outside reserve fund" within the meaning of the
REMIC Provisions, beneficially owned by the related Mortgage Loan Seller or the
Column Performance Guarantor, as applicable, for federal income tax purposes,
which shall be taxable on all reinvestment income, if any, thereon. 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
related Mortgage Loan Seller (or, if it is the party that delivered such amount,
the Column Performance Guarantor) may obtain a release of the Purchase Price
Security Deposit for any Mortgage Loan (net of any amounts payable therefrom as
contemplated by the first sentence of this paragraph) 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. Any such repurchase or replacement of a Mortgage Loan shall
be on a whole loan, servicing released basis.

            If one or more (but not all) of the Mortgage Loans constituting a
Cross-Collateralized Group are to be repurchased or replaced by a Mortgage Loan
Seller or the Column Performance Guarantor, as contemplated by this Section
2.03, then, prior to the subject repurchase or substitution, the applicable
Master Servicer shall use its reasonable efforts, subject to the terms of the
affected Mortgage Loans, to prepare and, to the extent necessary and
appropriate, have executed by the related Borrower and record, such
documentation as may be necessary to terminate the cross-collateralization
between the Mortgage Loans in such Cross-Collateralized Group that are to be
repurchased or replaced, on the one hand, and the remaining Mortgage Loans
therein, on the other hand, such that those two groups of Mortgage Loans are
each secured only by the Mortgaged Properties identified in the Mortgage Loan
Schedule as directly corresponding thereto; provided that no such termination
shall be effected unless and until the related Mortgage Loan Seller or the
Column Performance Guarantor, as applicable, delivers to the Trustee and the
applicable Master Servicer (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 the
Upper-Tier REMIC or Lower-Tier REMIC or an Adverse Grantor Trust Event with
respect to the Grantor Trust, (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 (iii) written consent from the
Controlling Class Representative (which consent may be given or withheld in its
sole discretion); and provided, further, that the related Mortgage Loan Seller
or the Column Performance Guarantor, as applicable, may, at its option,
repurchase or replace the entire Cross-Collateralized Group without termination
of the cross-collateralization. If any Mortgage Loan Seller or the Column
Performance Guarantor repurchases one or more (but not all) of the Mortgage
Loans constituting a Cross-Collateralized Group as contemplated in this
paragraph, in addition to the satisfaction of the delivery of the items set
forth in the immediately preceding sentence, the Crossed Mortgage Loan
Repurchase Criteria shall have been satisfied. To the extent necessary and
appropriate, the Trustee shall execute (or, subject to Section 3.10, provide the
applicable Master Servicer with a limited power of attorney that enables the
applicable Master Servicer to execute) the loan documentation referred to in the
second preceding sentence; provided that the Trustee shall not be liable for any
misuse of any such power of attorney by the applicable Master Servicer. The
applicable Master Servicer shall advance all costs and expenses incurred by the
Trustee and the applicable Master Servicer with respect to any
Cross-Collateralized Group pursuant to this paragraph, and such advances shall
(i) constitute and be reimbursable as Servicing Advances and (ii) be included in
the calculation of Purchase Price for the Mortgage Loan(s) to be repurchased or
replaced. Neither the applicable Master Servicer nor the applicable Special
Servicer shall be liable to any Certificateholder or any other party hereto if
the cross-collateralization of any Cross-Collateralized Group cannot be
terminated as contemplated by this paragraph for any reason beyond the control
of the applicable Master Servicer or the applicable Special Servicer, as the
case may be.

            If the cross-collateralization of any Cross-Collateralized Group of
Mortgage Loans cannot be terminated as contemplated by the prior paragraph for
any reason (including, but not limited to, the failure of the related Mortgage
Loan Seller or the Column Performance Guarantor, as the case may be, to satisfy
any of the conditions set forth in the first proviso to the first sentence of
the prior paragraph), and if the related Mortgage Loan Seller or the Column
Performance Guarantor, as the case may be, has not elected to purchase the
entire affected Cross-Collateralized Group, then the affected
Cross-Collateralized Group will be treated as a single Mortgage Loan for
purposes of (i) determining whether the subject Breach or Document Defect is a
Material Breach or a Material Document Defect, as the case may be, and (ii)
applying remedies, including repurchase and substitution.

            Whenever one or more mortgage loans are substituted for a Defective
Mortgage Loan by a Mortgage Loan Seller or the Column Performance Guarantor, as
contemplated by this Section 2.03, the applicable Master Servicer shall direct
the 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 Mortgage Loan as contemplated by this Section 2.03 if the Mortgage
Loan to be replaced was itself a Replacement Mortgage Loan, in which case,
absent a cure of the relevant Material Breach or Material Document Defect, the
affected Mortgage Loan will be required to be repurchased as contemplated
hereby. Monthly Payments due with respect to each Replacement Mortgage Loan (if
any) after the related date of substitution, and Monthly Payments due with
respect to each corresponding Deleted Mortgage Loan (if any) after the related
Due Date in March 2003 and received by the applicable Master Servicer or the
applicable Special Servicer on behalf of the Trust on or prior to the related
date of substitution, shall be part of the Trust Fund. Monthly Payments due with
respect to each Replacement Mortgage Loan (if any) on or prior to the related
date of substitution, and Monthly Payments due with respect to each
corresponding Deleted Mortgage Loan (if any) and received by the applicable
Master Servicer or the applicable Special Servicer on behalf of the Trust after
the related date of substitution, shall not be part of the Trust Fund and are to
be remitted by the applicable Master Servicer to the party effecting the related
substitution promptly following receipt.

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

            The reasonable "out-of-pocket" costs and expenses incurred by the
applicable Master Servicer, the applicable Special Servicer and/or the Trustee
pursuant to this Section 2.03(b), including reasonable attorney fees and
expenses, shall constitute Servicing Advances to the extent not collected from
the related Mortgage Loan Seller or the Column Performance Guarantor 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 applicable
Master Servicer to the effect that the full amount of the Purchase Price or
Substitution Shortfall Amount (as the case may be) for any Mortgage Loan
repurchased or replaced by the related Mortgage Loan Seller or the Column
Performance Guarantor, 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 Mortgage Loan (if any) to be substituted for
a Deleted Mortgage Loan, together with any certifications and/or opinions
required pursuant to Section 2.03(b) to be delivered by the party effecting the
repurchase/substitution, the Trustee shall (i) release or cause the release of
the Mortgage File and any Additional Collateral held by or on behalf of the
Trustee for the Deleted Mortgage Loan to the party effecting the
repurchase/substitution or its designee and (ii) execute and deliver such
endorsements and instruments of release, transfer and/or assignment, in each
case without recourse, as shall be provided to it and are reasonably necessary
to vest in the party effecting the repurchase/substitution or its designee the
legal and beneficial ownership of the Deleted Mortgage Loan (including any
property acquired in respect thereof or proceeds of any insurance policy with
respect thereto) and the related Mortgage Loan Documents, and the applicable
Master Servicer shall notify the affected Borrowers of the transfers of the
Deleted Mortgage Loan(s) and any Replacement Mortgage Loan(s). In connection
with any such repurchase or substitution by the related Mortgage Loan Seller or
the Column Performance Guarantor, each of the applicable Master Servicer and the
applicable Special Servicer shall deliver to the party effecting the
repurchase/substitution or its designee any portion of the related Servicing
File, together with any Escrow Payments, Reserve Funds and Additional
Collateral, held by or on behalf of the applicable Master Servicer or the
applicable Special Servicer, as the case may be, with respect to the Deleted
Mortgage Loan, in each case at the expense of the party effecting the
repurchase/substitution. The Trustee shall notify the related B Loan Holder of
any repurchase regarding an A Loan. The reasonable "out-of-pocket" costs and
expenses, including reasonable attorneys' fees and expenses, incurred by the
applicable Master Servicer, the applicable Special Servicer and/or the Trustee
pursuant to this Section 2.03(c), to the extent not collected from the related
Mortgage Loan Seller or the Column Performance Guarantor 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 Mortgage Loan.

            (d) If, on or after September 13, 2004, any Mortgage Loan Seller or
the Column Performance Guarantor receives notice of a Material Document Defect
with respect to any of its Mortgage Loans, which Material Document Defect
constitutes a Recording Omission, then such Mortgage Loan Seller or the Column
Performance Guarantor, as the case may be, may, with the written consent of the
Controlling Class Representative, which consent may be granted or withheld in
its sole discretion, and written confirmation from each Rating Agency that the
following arrangement will not result in an Adverse Rating Event with respect to
any Class of Rated Certificates, in lieu of repurchasing or replacing such
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
applicable Master Servicer; provided that if such Mortgage Loan Seller or the
Column Performance Guarantor, as the case may be, has already established a
Purchase Price Security Deposit with respect to such Mortgage Loan in accordance
with Section 2.03(b) due to a Material Document Defect, which constitutes a
Recording Omission, the outstanding balance of such Purchase Price Security
Deposit (when, if applicable, combined with an additional amount being tendered
by such Mortgage Loan Seller or the Column Performance Guarantor) is not less
than the amount of the required Recording Omission Reserve and the establishment
of a Recording Omission Reserve will not result in an Adverse Rating event with
respect to any Class of Rated Certificates, then the existing Purchase Price
Security Deposit (when, if applicable, combined with an additional amount being
tendered by such Mortgage Loan Seller or the Column Performance Guarantor) shall
constitute the establishment of a Recording Omission Reserve with respect to
such Mortgage Loan for purposes of this Section 2.03(d). In furtherance of the
preceding sentence, (A) the applicable Master Servicer shall establish one or
more accounts (collectively, the "Special Reserve Account") with respect to the
subject Mortgage Loan, each of which shall be an Eligible Account; (B) the
applicable Master Servicer shall deposit any Recording Omission Reserve into the
Special Reserve Account within one Business Day after receipt; and (C) the
applicable Master Servicer shall administer the Special Reserve Account in
accordance with the terms of the related Mortgage Loan Purchase Agreement. In
the event that such 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 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, such 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 any Mortgage Loan Seller or the Column Performance Guarantor with
respect to any Mortgage Loan shall be released to such Mortgage Loan Seller or
the Column Performance Guarantor, as the case may be, by the applicable Master
Servicer upon the earlier of (i) the curing of all Recording Omissions with
respect to such Mortgage Loan and (ii) the removal of such Mortgage Loan from
the Trust Fund. The Special Reserve Account, and any Recording Omission Reserves
and Recording Omission Credits, shall (a) be part of the Trust Fund but outside
either Trust REMIC or the Grantor Trust and (b) be an "outside reserve fund"
within the meaning of the REMIC Provisions, beneficially owned by the related
Mortgage Loan Seller or the Column Performance Guarantor, as applicable, for
federal income tax purposes, which shall be taxable on all reinvestment income,
if any, thereon. The investment of funds in the Special Reserve Account shall be
governed by the terms of the respective Mortgage Loan Purchase Agreements.

            (e) If the Mortgage Loan Seller disputes that a Material Document
Defect or 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 affected Mortgage Loan from the Trust or
(iii) to replace such Mortgage Loan with a Qualifying Substitute Mortgage Loan,
each in accordance with the related Mortgage Loan Purchase Agreement, then
provided that (i) at least the applicable Initial Resolution Period has expired
and (ii) the Mortgage Loan is then in default and is then a Specially Serviced
Mortgage Loan, the applicable Special Servicer may, subject to the Servicing
Standard, modify, work-out or foreclose, sell or otherwise liquidate (or permit
the liquidation of) the 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 (it being understood
and agreed that the foregoing is not intended to otherwise delay the actions of
the applicable Special Servicer with respect to a Specially Serviced Mortgage
Loan).

            The related Mortgage Loan Seller shall be notified promptly and in
writing by the applicable 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 the related
Mortgage Loan Seller, the related Mortgage Loan 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 related Mortgage Loan Seller shall have three (3)
Business Days to purchase such REO Property from the date that it was notified
of such offer. The applicable Special Servicer shall be obligated to provide the
related Mortgage Loan Seller with the most recent appraisal or other third-party
reports relating to such REO Property within its possession to enable the
related Mortgage Loan Seller to evaluate such REO Property. Any sale of a
Mortgage Loan, or foreclosure upon such Mortgage Loan and sale of an REO
Property, to a Person other than the related Mortgage Loan Seller shall be (i)
without recourse of any kind (either expressed or implied) by such Person
against the related Mortgage Loan Seller or, if applicable, the Column
Performance Guarantor and (ii) without representation or warranty of any kind
(either expressed or implied) by the related Mortgage Loan Seller or, if
applicable, the Column Performance Guarantor 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 Mortgage Loan or REO Property) shall not prejudice any claim against
the related Mortgage Loan Seller for repurchase of the subject Mortgage Loan or
REO Property. The provisions of this Section 2.03 regarding remedies against the
related Mortgage Loan 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 related Mortgage Loan Seller fails to correct or cure the
Material Document Defect or Material Breach or purchase the REO Property, then
the provisions above regarding notice of offers related to such REO Property and
the related Mortgage Loan Seller's right to purchase such REO Property shall
apply. If a court of competent jurisdiction issues a final order that the
related Mortgage Loan Seller is or was obligated to repurchase the related
Mortgage Loan or REO Property or the related Mortgage Loan 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 this
Agreement, the related Mortgage Loan Seller 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 Mortgage Loan 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) The related Mortgage Loan Purchase Agreement and, in the case of
Column Mortgage Loans, the Column Performance Guarantee, provide the sole
remedies available to the Certificateholders, or the Trustee on their behalf,
respecting any Breach or Document Defect. If, in connection with any unremedied
Material Breach or Material Document Defect, a Mortgage Loan Seller (or, in the
case of a Column Mortgage Loan, each of Column and the Column Performance
Guarantor) defaults on its obligations to repurchase or replace, to post cash or
a letter of credit with respect to, or to reimburse the Trust for certain costs
and expenses relating to, any Mortgage Loan as contemplated by this Section
2.03, the applicable Master Servicer shall (and the applicable Special Servicer
may) promptly notify the Trustee, and the Trustee shall notify the
Certificateholders. Thereafter, the applicable Master Servicer shall (and the
applicable Special Servicer may) take such actions on behalf of the Trust with
respect to the enforcement of such repurchase/substitution obligations (and if
the applicable Master Servicer (or the applicable Special Servicer) is notified
or otherwise becomes aware of a default on the part of any Mortgage Loan Seller
in respect of its obligations under the second paragraph of Section 2(c) of the
related Mortgage Loan Purchase Agreement, the applicable Master Servicer shall
(and the applicable Special Servicer may) also take such actions on behalf of
the Trust with respect to the enforcement of such obligations of such Mortgage
Loan Seller), including the institution and prosecution of appropriate legal
proceedings, as the applicable Master Servicer (or, if applicable, the
applicable Special Servicer) shall determine are in the best interests of the
Certificateholders (taken as a collective whole). Any and all reasonable
"out-of-pocket" costs and expenses incurred by the applicable Master Servicer,
the applicable Special Servicer and/or the Trustee pursuant to this Section
2.03(f), including, reasonable attorney's fees and expenses, to the extent not
collected from the related Mortgage Loan Seller or the Column Performance
Guarantor 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 Mortgage Loan.

            (g) If the applicable Mortgage Loan Seller or the Column Performance
Guarantor (in the case of a Column Mortgage Loan), incurs any expense in
connection with the curing of any Breach which also constitutes a default under
the related Mortgage Loan, such Mortgage Loan Seller or the Column Performance
Guarantor, as the case may be, shall have a right, and shall be subrogated to
the rights of the Trustee, as the holder of such Mortgage Loan, to recover the
amount of such expenses from the related Borrower; provided, however, that the
rights of such Mortgage Loan Seller or the Column Performance Guarantor, as the
case may be, pursuant to this Section 2.03(g) shall be junior, subject and
subordinate to the rights of the Trust Fund, the applicable Master Servicer and
the applicable Special Servicer to recover amounts owed by the related Borrower
under the terms of such Mortgage Loan, including, without limitation, the rights
to recover unreimbursed Advances, accrued and unpaid interest on Advances at the
Reimbursement Rate and unpaid or unreimbursed expenses of the Trust Fund, the
applicable Master Servicer or the applicable Special Servicer allocable to such
Mortgage Loan; provided, further, that if and to the extent that such expenses
of such Mortgage Loan Seller or the Column Performance Guarantor, as the case
may be, in connection with such Mortgage Loan exceed five percent of the then
outstanding principal balance of such Mortgage Loan, then its rights to
reimbursement pursuant to this Section 2.03(g) with respect to such Mortgage
Loan and such excess expenses shall not be exercised until the payment in full
of such Mortgage Loan (as such Mortgage Loan may be amended or modified pursuant
to the terms of this Agreement). Notwithstanding any other provision of this
Agreement to the contrary, the applicable Master Servicer or, with respect to a
Specially Serviced Mortgage Loan, the applicable Special Servicer, shall not
have any obligation pursuant to this Agreement to collect such reimbursable
amounts on behalf of such Mortgage Loan Seller or the Column Performance
Guarantor, as the case may be; provided, however, that the preceding clause
shall not operate to prevent the applicable Master Servicer or, with respect to
a Specially Serviced Mortgage Loan, the applicable Special Servicer, from using
reasonable efforts, exercised in its sole discretion, to collect such amounts to
the extent consistent with the Servicing Standard, so long as the applicable
Master Servicer or, with respect to a Specially Serviced Mortgage Loan, the
applicable Special Servicer determines in the exercise of its sole discretion
consistent with the Servicing Standard that its actions to collect such amounts
will not impair the applicable Master Servicer's and/or the applicable Special
Servicer's collection and recovery of principal, interest and other sums due
with respect to the related Mortgage Loan and, if applicable, B Loan, which
would otherwise be payable to the Trust, the applicable Master Servicer, the
applicable Special Servicer, the Trustee or the Certificateholders and, if
applicable, the B Loan Holder, pursuant to the terms of this Agreement,
provided, that in no event will the failure of Borrower to pay such reimbursable
amounts result in the Borrower being called in default under the Mortgage Loan,
either the applicable Master Servicer or the applicable Special Servicer
accelerating the Mortgage Loan or taking any enforcement action beyond making
demand for such reimbursable amount but, provided, further, in the event of the
applicable Special Servicer otherwise commencing enforcement action with respect
to a default other than the Borrower's failure to pay such reimbursable amounts,
the applicable Special Servicer may include such reimbursable amounts in the
amount sought from the Borrower in such enforcement action but payment of any
such reimbursable amounts shall be subordinate to the payment of all other sums
owed by the Borrower under the Mortgage Loan and payable to the Trust, the
Master Servicers, the Special Servicers or the Trustee. Any amounts reimbursed
to a Mortgage Loan Seller or the Column Performance Guarantor from either Trust
REMIC with respect to any amounts paid from the Purchase Price Security Deposit
Account, Special Reserve Account or any Recording Omission Reserve or Recording
Omission Credits shall be treated as distributions from such Trust REMIC to such
Mortgage Loan Seller or the Column Performance Guarantor, as applicable, as
beneficial owners of such Purchase Price Security Deposit Account, Special
Reserve Account, Recording Omission Reserve or Recording Omission Credit, as
applicable.

            Section 2.04 Representations and Warranties of the Depositor

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

      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 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 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 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
      Mortgage Loans to the Trustee, pursuant to Section 2.01(b).

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

            (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.

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

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

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

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

      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 reasonable judgment of the
      General Master Servicer, is likely to affect materially and adversely
      either the ability of the General Master Servicer to perform its
      obligations under this Agreement or the financial condition of the General
      Master Servicer.

            (iii) The General Master Servicer has the full corporate power and

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

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

      consummation by the General 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

      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 General Master
      Servicer's knowledge, threatened against the General Master Servicer the

      is likely to materially and adversely affect either the ability of the
      General Master Servicer to perform its obligations under this Agreement or
      the financial condition of the General Master Servicer.

            (viii) The General Master Servicer has errors and omissions

      will be in effect as of the Closing Date with respect to the General
      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 General Master
Servicer set forth in Section 2.05(a) shall survive the execution and delivery

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 General Master Servicer shall be deemed to have
made, as of the date of its succession, each of the representations and
warranties set forth in Section 2.05(a), subject to such appropriate

      agreement or other instrument to which it is a party or by which it is
      bound, which default or breach, in the reasonable judgment of the General
      Special Servicer, is likely to affect materially and adversely either the

      this Agreement or the financial condition of the General Special Servicer.

warranties set forth in Section 2.06(a), subject to such appropriate

      Loan and to perform its obligations under this Agreement.

            (ii) The Co-op Master Servicer's execution and delivery of,
      performance under and compliance with this Agreement, will not violate the
      Co-op 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 Co-op Master Servicer, is likely to affect materially and
      adversely either the ability of the Co-op Master Servicer to perform its
      obligations under this Agreement or the financial condition of the Co-op
      Master Servicer.

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

      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 Co-op 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

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

      agreement or other instrument to which it is a party or which is
      applicable to it or any of its assets, which default, in the good faith
      and reasonable judgment of the Co-op Special Servicer, is likely to affect

      any federal, state or local governmental or regulatory authority, which
      violation, in the Co-op Special Servicer's good faith and reasonable

      (insofar as such enforceability is dependent upon compliance by the
      Trustee with such laws) and to perform its obligations under this
      Agreement.

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

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

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

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

            Section 2.10  Issuance of Uncertificated Lower-Tier Interests;
                          Execution of Certificates

            (a) The Trustee hereby acknowledges the assignment to it of the

                 ADMINISTRATION AND SERVICING OF THE TRUST FUND


            Section 3.01  Administration of the Mortgage Loans

            (a) The General Master Servicer shall be the Master Servicer with
respect to all the Trust Assets other than the Co-op Trust Assets and, as such,

services, as shall be required of such Master Servicer hereunder with respect to
such of the Co-op Trust Assets as constitute Specially Serviced Mortgage Loans

Assets (other than the Co-op Trust Assets) as constitute Specially Serviced
Mortgage Loans and REO Properties and shall render such incidental services as

such Special Servicer with respect to such of the Co-op Trust Assets as
constitute Performing Mortgage Loans.

            (b) Each of the Master Servicers and the Special Servicers shall
service and administer the Mortgage Loans and any REO Properties that it is
obligated to service and administer pursuant to this Agreement, for the benefit
of the Certificateholders (as a collective whole), in accordance with: (i) any
and all applicable laws; (ii) the express terms of this Agreement and the
respective Mortgage Loan Documents (and, in the case of each A/B Loan Pair, the
related A/B Intercreditor Agreement); and (iii) to the extent consistent with
the foregoing, the Servicing Standard. Subject to the foregoing, each Master
Servicer and Special Servicer shall each have full power and authority, acting
alone or through Sub-Servicers, to do or cause to be done any and all things in
connection with such servicing and administration which it may deem necessary or
desirable. Without limiting the generality of the foregoing, each Master
Servicer (with respect to those Performing Mortgage Loans that it is obligated
to service and administer pursuant to this Agreement) and Special Servicer (with
respect to Specially Serviced Mortgage Loans that it is obligated to service and
administer pursuant to this Agreement), in its own name or in the name of the

deliver, on behalf of the Certificateholders, any affected B Loan Holder and the

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

cause to be so furnished, to such Master Servicer or Special Servicer, as
appropriate, any limited powers of attorney and other documents (each of which
shall be prepared by such Master Servicer or Special Servicer, as applicable)
necessary or appropriate to enable it to carry out its servicing and
administrative duties hereunder; provided, that the Trustee shall not be held
liable for any misuse of any such power of attorney by any Master Servicer or
Special Servicer.

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

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

            Section 3.02  Collection of Mortgage Loan Payments

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

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

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

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

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

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

            (d) Each Master Servicer shall establish and maintain, as
applicable, one or more accounts (the "Reserve Accounts"), in which all Reserve
Funds, if any, received by it with respect to the Mortgage Loans as to which it
is the applicable Master Servicer shall be deposited and retained. The General
Master Servicer shall maintain the Reserve Accounts with respect to all of the
Mortgage Loans (other than the Co-op Mortgage Loans), and the Co-op Master
Servicer shall maintain the Reserve Accounts with respect to the Co-op Mortgage
Loans. As and to the extent consistent with the Servicing Standard and the
related Mortgage Loan Documents, each Master Servicer may make withdrawals of
amounts so deposited, and draws under any Letter of Credit delivered in lieu of
Reserve Funds, 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 or such Letter of Credit was delivered and, in the case of a Reserve
Account constituting debt service reserve accounts, to apply amounts on deposit
therein in respect of principal and interest on the related Mortgage Loan. In
addition, as and to the extent consistent with the Servicing Standard and the
related Mortgage Loan Documents, each Master Servicer may make withdrawals of
amounts so deposited, and draws under any Letter of Credit so delivered, to
prepay the Mortgage Loan in the event certain leasing or other economic criteria
are not satisfied at the related Mortgaged Property (but only if such prepayment
is required by the related Mortgage Loan Documents or continuing to hold such
funds or Letter of Credit as Additional Collateral is not consistent with the
Servicing Standard), to pay amounts due and owing under the Mortgage Loan
following an event of default, or to release such amounts to the related
Borrower or otherwise apply such amounts for any other appropriate purpose in
the event that such criteria are satisfied, and each Master Servicer may return
any Letter of Credit so delivered to the related Borrower; provided that,
notwithstanding the foregoing, such 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) such
Master Servicer has so notified the applicable Special Servicer in writing and
has provided such Special Servicer with any written or electronic information in
such Master Servicer's possession regarding such Mortgage Loan or the related
Mortgaged Property that such Special Servicer may reasonably request within ten
Business Days of receiving such written notice; and (ii) subject to Section
3.24, the applicable Special Servicer has consented to such release of any such
Earn-Out Reserve Funds or return of any related Letter of Credit (such consent
to be given or withheld in accordance with the Servicing Standard and to be
deemed given if the applicable Special Servicer does not object in writing to
such release of any such Earn-Out Reserve Funds or return of any such Letter of
Credit within fifteen (15) Business Days after receiving such additional
information from the applicable Master Servicer (or, if it did not request
additional information, within ten Business Days after receiving such notice)).
Subject to the terms of the related Mortgage Loan Documents, each Reserve
Account shall be an Eligible Account. Interest and other income, if any, earned
on funds on deposit in any Reserve Account held by the applicable Master
Servicer (to the extent of any Net Investment Earnings with respect to such
Reserve Account for any Collection Period), shall be for the benefit of and
payable to such Master Servicer, unless otherwise required to be paid to the
related Borrower by law or the terms of the related Mortgage Loan. If a Master
Servicer shall deposit in a Reserve Account maintained by it any amount not
required to be deposited therein, it may at any time withdraw such amount from
such Reserve Account, any provision herein to the contrary notwithstanding. Any
out-of-pocket expenses incurred by the applicable Master Servicer to enable such
Master Servicer to make any draw under any Letter of Credit shall constitute a
Servicing Advance, and such 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.

            (e) To the extent an operations and maintenance plan is required to
be established and executed pursuant to the terms of a Mortgage Loan, the
applicable Master Servicer shall request from the Borrower written confirmation
thereof within a reasonable time after the later of the Closing Date and the
date as of which such plan is required to be established or completed. To the
extent any other action or remediation with respect to environmental matters is
required to have been taken or completed pursuant to the terms of a Mortgage
Loan, the applicable Master Servicer shall request from the Borrower written
confirmation of such action and remediations within a reasonable time after the
later of the Closing Date and the date as of which such action or remediations
are required to have been taken or completed. To the extent that a Borrower
shall fail to promptly respond to any inquiry described in this Section 3.03(e),
the applicable Master Servicer shall notify the Trustee, the applicable Special
Servicer and the Controlling Class Representative. The applicable Master
Servicer shall promptly notify the Trustee, the applicable Special Servicer and
the Controlling Class Representative if the Master Servicer shall determine that
any Borrower has failed to perform its obligations under the related Mortgage
Loan in respect of environmental matters.

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

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

            (a) Each 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 funds and general assets. In connection therewith, each
Master Servicer shall establish and maintain one or more segregated accounts
(collectively, the "Collection Account"), in which the funds described below are
to be deposited and held on behalf of the Trustee in trust for the benefit of
the Certificateholders. Each account that constitutes the Collection Account
shall be an Eligible Account. Each Master Servicer shall deposit or cause to be
deposited in the applicable Collection Account, within one Business Day of
receipt by it (in the case of payments by Borrowers or other collections on the
Mortgage Loans) or as otherwise required hereunder, the following payments and
collections received or made by or on behalf of such Master Servicer in respect
of the Mortgage Pool subsequent to the Closing Date (other than in respect of
scheduled payments of principal and interest due and payable on the Mortgage
Loans on or before their respective Due Dates in March 2003 (or, in the case of
a Replacement Mortgage Loan, on or before the related date of substitution),
which payments shall be delivered promptly to the related Mortgage Loan Seller
or its designee, with negotiable instruments endorsed as necessary and
appropriate without recourse):

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

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

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

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

            (v) any amounts required to be deposited by such 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 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 from any REO Account
      pursuant to Section 3.16(c) or from an A/B Loan Pair Custodial Account
      pursuant to Section 3.04(f);

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

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

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

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

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

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

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

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

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

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

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

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

            (f) If (i) any A/B Material Default occurs and is continuing (and,
as a result, the related B Loan is being serviced hereunder) or (ii) the
Mortgaged Property securing any A/B Loan Pair has become REO Property, the
applicable Master Servicer shall establish and maintain, or cause to be
established and maintained, an A/B Loan Pair Custodial Account, into which the
applicable Master Servicer shall deposit or cause to be deposited on a daily
basis (and in no event later than the Business Day following the receipt of
available funds), except as otherwise specifically provided herein, the
following payments and collections received after the Cut-off Date (other than
payments of principal and interest on the applicable A/B Loan Pair due and
payable on or before the Cut-off Date) and payments (other than Principal
Prepayments) received by it on or prior to the Cut-off Date but allocable to a
period subsequent thereto:

            (i) all payments on account of principal, including Principal
      Prepayments, on such A/B Loan Pair; and

            (ii) all payments on account of interest, including Post-ARD
      Additional Interest, on such A/B Loan Pair; and

            (iii) all Insurance Proceeds and Condemnation Proceeds received in
      respect of such A/B Loan Pair; and

            (iv) all Liquidation Proceeds; and

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

            (vi) any amounts required to be deposited by the General Master
      Servicer pursuant to Section 3.06 in connection with losses incurred with
      respect to Permitted Investments of funds held in such A/B Loan Pair
      Custodial Account.

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

            Within one Business Day of receipt of any of the amounts described
in the second preceding paragraph with respect to any Specially Serviced Loan
that is part of an A/B Loan Pair during the period that the related B Loan is
being serviced hereunder, the applicable Special Servicer shall remit such
amounts to the applicable Master Servicer for deposit in the related A/B Loan
Pair Custodial Account pursuant to the second preceding paragraph. Any amounts
received by the applicable Special Servicer with respect to an REO Property that
relates to an A/B Loan Pair shall be deposited into the REO Account and remitted
to the applicable Master Servicer for deposit into the related A/B Loan Pair
Custodial Account pursuant to Section 3.16(c).

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

            (g) Notwithstanding the foregoing or any other provision to the
contrary in this Agreement, the Trustee may maintain the Distribution Account,
the Interest Reserve Account and the Excess Liquidation Proceeds Account as
three separate subaccounts of a single Eligible Account; provided that: (i) all
deposits into and withdrawals from such single Eligible Account shall be made in
the same manner as would be the case if the Distribution Account, the Interest
Reserve Account and the Excess Liquidation Proceeds Account were maintained as
three separate accounts; (ii) all distributions on the Certificates 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
Account were maintained as three separate accounts; (iii) the Trustee shall make
debits and credits to those three subaccounts in a manner consistent with the
provisions of this Agreement governing transfers of funds between the
Distribution Account, the Interest Reserve Account and the Excess Liquidation
Proceeds Account, as the case may be; (iv) the Trustee's maintaining the
Distribution Account, the Interest Reserve Account and the Excess Liquidation
Proceeds Account as three separate subaccounts of a single Eligible Account (as
opposed to in the form of three separate Eligible Accounts) shall not materially
and adversely affect any of the Certificateholders; and (v) such single Eligible
Account shall be entitled "[name of Trustee], as Trustee, in trust for the
registered holders of Credit Suisse First Boston Mortgage Securities Corp.,
Commercial Mortgage Pass Through Certificates, Series 2003-CPN1, Distribution
Account, Interest Reserve Account and Excess Liquidation Proceeds Account."

            Section 3.05  Permitted Withdrawals From the Collection Account, the
                          Distribution Account, the Interest Reserve Account

            (ii) to reimburse itself, the Trustee or any Fiscal Agent, as
      applicable, for unreimbursed P&I Advances (to the extent not previously
      reimbursed in the form of a cure payment from the B Loan Holder) made
      thereby (in each case, with its own funds), with respect to those Mortgage
      Loans as to which such Master Servicer is the applicable Master Servicer
      and/or any successor REO Loans in respect thereof, such Master Servicer's,
      the Trustee's and any Fiscal Agent's, as the case may be, respective
      rights to reimbursement pursuant to this clause (ii) with respect to any
      P&I Advance (other than Nonrecoverable P&I Advances, which are
      reimbursable pursuant to clause (vii) below) being limited to amounts that
      represent Late Collections of interest and principal received in respect
      of the particular Mortgage Loan or REO Mortgage Loan as to which such P&I
      Advance was made (net of related Master Servicing Fees and/or Workout

      any such Mortgage Loan or such REO Mortgage Loan being limited to
      collections of interest thereon or with respect thereto;

            (iv) to pay the applicable Special Servicer, out of general
      collections on the Mortgage Loans in, and any REO Properties relating to,
      earned and unpaid Special Servicing Fees in respect of each related
      Specially Serviced Mortgage Loan and related REO Mortgage Loan, but only
      if and to the extent that such Special Servicing Fees relate to Mortgage
      Loans and/or REO Properties as to which such Special Servicer is the
      applicable Special Servicer;

            (v) to pay the applicable Special Servicer (or, if applicable, any
      predecessor thereto) earned and unpaid Workout Fees and Liquidation Fees
      to which it is entitled pursuant to, and from the sources contemplated by,
      the second and third paragraphs of Section 3.11(c), but only if and to the
      extent that such Special Servicing Fees, Workout Fees and Liquidation Fees
      relate to Mortgage Loans and/or REO Properties as to which such Special
      Servicer is the applicable Special Servicer;

            (vi) to reimburse itself, the applicable Special Servicer, the
      Trustee or any Fiscal Agent, as applicable, for any unreimbursed Servicing
      Advances made thereby (in each case, with its own funds), the applicable
      Master Servicer's, the applicable Special Servicer's, the Trustee's and

      than Nonrecoverable Servicing Advances, which are reimbursable pursuant to
      clause (vii) below) being limited to (A) payments made by the related
      Borrower that are allocable to cover the item in respect of which such
      Servicing Advance was made, and (B) Insurance Proceeds, Condemnation

      such Servicing Advance was made;

            (vii) (A) first, to reimburse itself, the applicable Special
      Servicer, the Trustee or any Fiscal Agent, as applicable, out of general
      collections on the Mortgage Loans and any REO Properties, for any
      unreimbursed Advances made thereby that have been determined to be
      Nonrecoverable Advances, and (B) second, if such Master Servicer shall
      have received from the other Master Servicer an Officer's Certificate
      setting forth that (1) such other Master Servicer, either Special
      Servicer, the Trustee or any Fiscal Agent, as applicable, is entitled to

      Servicer is the applicable Master Servicer (and setting forth the nature
      and amount of such unreimbursed Nonrecoverable Advance and the party
      entitled to reimbursement therefor) and (2) such other Master Servicer has
      insufficient funds then on deposit in its Collection Account, then to

      applicable Master Servicer, provided that the applicable Master Servicer
      may reimburse itself in installments as it may choose in its sole
      discretion;

            (viii) to pay itself, the applicable Special Servicer, the Trustee
      or any Fiscal Agent, as applicable, any Advance Interest then due and
      owing to such Person, out of Default Charges collected on the Mortgage
      Loan or REO Mortgage Loan, as the case may be, as to which the related
      Advance was made, as and to the extent contemplated by Section 3.26;

            (ix) to the extent that, during any Collection Period, such Master
      Servicer has reimbursed or is reimbursing itself, the applicable Special
      Servicer, the Trustee or any Fiscal Agent, as applicable, for any
      unreimbursed Advance pursuant to clause (ii), (vi) or (vii) above or
      pursuant to Section 3.03(c), and insofar as payment has not already been
      made, and the related Default Charges then on deposit in the Collection
      Account are not sufficient to make such payment pursuant to clause (viii)
      above, to pay itself, such Special Servicer, the Trustee or such Fiscal
      Agent, as the case may be, out of general collections on the Mortgage
      Loans and any REO Properties, any related Advance Interest accrued and
      payable on the portion of such Advance so reimbursed or being reimbursed;

            (x) to pay any outstanding expense, other than Advance Interest,
      that was incurred with respect to any related Mortgage Loan or related REO
      Property as to which such Master Servicer is the applicable Master
      Servicer and that, if paid from a source other than Default Charges on
      such Mortgage Loan or the related REO Mortgage Loan, as the case may be,
      would constitute an Additional Trust Fund Expense, such payment to be
      made, as and to the extent contemplated by Section 3.26, out of Default
      Charges collected on the Mortgage Loan or REO Mortgage Loan, as the case
      may be, that relates to such expense;

            (xi) to pay itself any items of Additional Master Servicing
      Compensation, and to pay to the applicable Special Servicer any items of
      Additional Special Servicing Compensation, in each case on deposit in the
      Collection Account from time to time;

            (xii) to pay any unpaid Liquidation Expenses incurred with respect
      to any related Mortgage Loan or REO Property as to which such Master
      Servicer is the applicable Master Servicer, such payments to be made,
      first, out of Insurance Proceeds, Condemnation Proceeds or Liquidation
      Proceeds and, if applicable, REO Revenues received in respect of such
      Mortgage Loan or REO Property, as the case may be, and then, out of
      general collections on other Mortgage Loans and any REO Properties;

            (xiii) to pay, in accordance with Section 3.11(i), out of general
      collections on the Mortgage Loans and any REO Properties relating thereto,
      certain servicing expenses related to the Mortgage Loans and REO
      Properties as to which such Master Servicer is the applicable Master
      Servicer that would, if advanced, constitute Nonrecoverable Servicing
      Advances;

            (xiv) to pay, out of general collections on the Mortgage Loans and
      any REO Properties, costs and expenses incurred by the Trust pursuant to
      Section 3.09(c) with respect to any Mortgage Loan or REO Property as to
      which such Master Servicer is the applicable Master Servicer (other than
      the costs of environmental testing, which are to be covered by, and
      reimbursable as, a Servicing Advance);

            (xv) to pay itself, either Special Servicer, the Depositor, the
      Trustee, any Fiscal Agent, or any of their respective directors, officers,
      members, managers, employees and agents, as the case may be, out of
      general collections on the Mortgage Loans and any REO Properties relating
      thereto, 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 but only
      if and to the extent that such amounts relate to Mortgage Loans and/or REO
      Properties as to which such Master Servicer is the applicable Master
      Servicer;

            (xvi) to pay, out of general collections on the Mortgage Loans and
      any REO Properties relating thereto, any reasonable out-of-pocket cost or

      incurred by the Trustee pursuant to Section 3.17(a)(iii) in connection
      with providing advice to a Special Servicer with respect to any REO
      Property as to which such Master Servicer is the applicable Master
      Servicer;

            (xvii) to pay to each Master Servicer, each Special Servicer, the
      Trustee, any Fiscal Agent or the Depositor, as the case may be, any amount
      related to the Mortgage Loans and any REO Properties as to which such
      Master Servicer is the applicable Master Servicer, 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 not made in any
      other clause of this Section 3.05(a), it being acknowledged that this
      clause (xvii) shall not be construed to modify any limitation otherwise
      set forth in this Agreement on the time at which any Person is entitled to
      payment or reimbursement of any amount or the funds from which any such
      payment or reimbursement is permitted to be made;

            (xviii) to pay itself, either Special Servicer, a Mortgage Loan
      Seller, a Certificateholder or any other particular Person, as the case
      may be, with respect to each Mortgage Loan as to which such Master
      Servicer is the applicable Master Servicer and 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 thereon
      subsequent to the date of purchase;

            (xix) to pay amounts payable to any B Loan Holder under the related
      A/B Intercreditor Agreement;

            (xx) to reimburse itself for any prior Advance, including any
      interest accrued and payable thereon, made for which a cure payment from
      the B Loan Holder has been received, from such cure payment;

            (xxi) to transfer Excess Liquidation Proceeds to the Excess

            (xxiv) to pay for the recording cost of this Agreement;

            (xxv) to pay to the respective Mortgage Loan Sellers, amounts that
      represent Monthly Payments due on the Mortgage Loans on or before their
      respective Due Dates in March 2003 or, in the case of a Replacement
      Mortgage Loan, on or before the date on which such loan was added to the
      Trust Fund, if any, or in the case of a Deleted Mortgage Loan, amounts
      collected or received by the Trust with respect to such Mortgage Loan
      after the related date of replacement pursuant to Section 2.03(b);

            (xxvi) to withdraw amounts deposited in such Collection Account in
      error; and

            (xxvii) to clear and terminate such Collection Account at the
      termination of this Agreement pursuant to Section 9.01.

            If amounts on deposit in either Collection Account at any particular
time (after withdrawing any portion of such amounts deposited in such Collection
Account in error) are insufficient to satisfy all payments, reimbursements and
remittances to be made therefrom as set forth in clauses (ii) through (xviii),
above, then the corresponding withdrawals from such Collection Account shall be
made in the following priority and subject to the following rules: (y) 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 (z) if the payment, reimbursement or remittance can be made from any funds
on deposit in such Collection Account, then (following any withdrawals made from
such Collection Account in accordance with the immediately preceding clause (y)
above) such payment, reimbursement or remittance shall be made from the general
funds remaining on a pro rata basis with any and all other payments,
reimbursements or remittances to be made from such general funds; provided that
amounts payable pursuant to clauses (vii) and (ix) shall be paid, pro rata,
prior to any other such payments, reimbursements or remittances; and provided,
further, that amounts payable pursuant to clause (xv) shall be paid after the
amounts specified in the preceding proviso but prior to any other such payments,
reimbursements or remittances; and provided, further, that any reimbursements of
Advances in respect of any particular Mortgage Loan or REO Property out of a
Collection Account pursuant to any of clauses (ii), (vi) and (vii) above, and
any payments of interest thereon out of a Collection Account pursuant to either
of clauses (viii) and (ix) above, shall be made (to the extent of their
respective entitlements to such reimbursements and/or payments): first, to any
Fiscal Agent; second, to the Trustee; and third, pro rata, to the applicable
Master Servicer and the applicable Special Servicer.

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

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

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

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

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

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

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

            (b) The Trustee shall, from time to time, make or be deemed to make
withdrawals from the Lower-Tier 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 or deemed distributions of the Lower-Tier
      Distribution Amount pursuant to Section 4.01 and the amount of any
      Prepayment Premium and Yield Maintenance Charges distributable pursuant to
      Section 4.01(c) to the Upper-Tier Distribution Account;

            (ii) to pay itself or any of its directors, officers, employees and
      agents, as the case may be, any amounts payable or reimbursable to any
      such Person pursuant to Section 8.05, including the Trustee's Fee;

            (iii) to pay any Fiscal Agent or any of its directors, officers,
      employees and agents, as the case may be, any amounts payable or
      reimbursable to any such Person pursuant to Sections 8.05 and/or 8.13(a);

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

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

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

            (vii) to clear and terminate the Lower-Tier Distribution Account at
      the termination of this Agreement pursuant to Section 9.01.

            (c) On the Master Servicer Remittance Date in March of each year
(commencing in March 2004), and in any event on the Master Servicer Remittance
Date that occurs in the same calendar month as the Final Distribution Date, the
Trustee shall withdraw or be deemed to withdraw from the Interest Reserve
Account and deposit or be deemed to deposit in the Distribution Account all
Interest Reserve Amounts in respect of the Interest Reserve Mortgage Loans then
on deposit in the Interest Reserve Account.

            (d) On the Business Day prior to each Distribution Date, the Trustee
shall withdraw or be deemed to withdraw from the Excess Liquidation Proceeds
Account and deposit or be deemed to deposit in the Distribution Account, for
distribution on such Distribution Date, an amount equal to the lesser of (i) the
entire amount, if any, then on deposit in the Excess Liquidation Proceeds
Account and (ii) the excess, if any, of the aggregate amount distributable on
such Distribution Date pursuant to Sections 4.01(a) and 4.01(b), over the
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. The Trustee shall, from time to time, make
withdrawals from the Excess Liquidation Proceeds Account to pay itself interest
or other income earned on deposits in the Excess Liquidation Proceeds Account,
in accordance with Section 3.06(b) (but only to the extent of the Net Investment
Earnings, if any, with respect to the Excess Liquidation Proceeds Account for
each Collection Period).

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

            Section 3.06  Investment of Funds in the Collection Account,
                          Servicing Accounts, Reserve Accounts and the REO
                          Account

            (a) Each Master Servicer may direct (pursuant to a standing order or
otherwise) any depositary institution (including the Trustee) maintaining a
Collection Account, any A/B Loan Pair Custodial Account or any Servicing Account
or Reserve Account held by it, and each Special Servicer may direct (pursuant to
a standing order or otherwise) any depositary institution maintaining an 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, for purposes of this Section 3.06, 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, or with respect to Permitted Investments
of funds held in the Distribution Account no later than 12:00 p.m. on the next
succeeding Distribution Date; provided that any such investment of funds in any
Servicing Account or Reserve Account shall be subject to applicable law and the
terms of the related Mortgage Loan Documents; and provided, further, that the
funds in any Investment Account shall remain uninvested unless and until the
applicable Master Servicer, applicable Special Servicer or the Trustee, as
applicable, gives timely investment instructions with respect thereto pursuant
to this Section 3.06. All such Permitted Investments shall be held to maturity,
unless payable on demand. Any investment of funds in an Investment Account shall
be made in the name of the Trustee (in its capacity as such). Each Master
Servicer (with respect to Permitted Investments of amounts in its Collection
Account, its Servicing Accounts and its Reserve Accounts), each Special Servicer
(with respect to Permitted Investments of amounts in its REO Account) and the
Trustee (with respect to Permitted Investments of amounts in the Distribution
Account, the Interest Reserve Account or the Excess Liquidation Proceeds
Account), acting on behalf of itself, shall (i) be the "entitlement holder" of
any Permitted Investment that is a "security entitlement" and (ii) maintain
"control" of any Permitted Investment that is either a "certificated security"
or an "uncertificated security." For purposes of this Section 3.06(a), the terms
"entitlement holder," "security entitlement," "control," "certificated security"
and "uncertificated security" shall have the meanings given such terms in
Revised Article 8 (1994 Revision) of the UCC, and "control" of any Permitted
Investment by a Master Servicer or a 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, the party hereunder that maintains such account, whether it is a Master
Servicer, a Special Servicer or Trustee shall:

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

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

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

            (c) Except as otherwise expressly provided in this Agreement, if any
default occurs in the making of any payment due (or in any other performance
required) under any Permitted Investment, and if the applicable Master Servicer
(if such default is in respect of a Permitted Investment of funds in a
Collection Account or in any Reserve Account or Servicing Account) or the
applicable Special Servicer (if such default is in respect of a Permitted
Investment of funds in an REO Account), as applicable, is in default of its
obligations under Section 3.06(b), 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 Regular 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 applicable Master Servicer if the default is in
respect of a Permitted Investment of funds in a Collection Account or in any
Reserve Account or Servicing Account or by the applicable Special Servicer if
the default is in respect of a Permitted Investment of funds in an REO Account.
This provision is in no way intended to limit any actions that each Master
Servicer or each 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 Available Distribution Amount and the Master Servicer Remittance Amount,
the amounts so invested shall be deemed to remain on deposit in such Investment

                          Omissions and Fidelity Coverage

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

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

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

            (c) Promptly after (but in no event more than 30 days after) the
Closing Date, with respect to each of the Mortgage Loans for which it acts as
Master Servicer covered by an Environmental Insurance Policy, each Master
Servicer shall notify the insurer under such Environmental Insurance Policy and
take all other action necessary for the Trustee, on behalf of the
Certificateholders, to be an insured (and for such Master Servicer, on behalf of
the Trust, to make claims) under such Environmental Insurance Policy. In the
event that a Master Servicer has actual knowledge of any event (an "Insured
Environmental Event") giving rise to a claim under any Environmental Insurance
Policy in respect of any Mortgage Loan covered thereby, such Master Servicer
shall, in accordance with the terms of such Environmental Insurance Policy and
the Servicing Standard, timely make a claim thereunder with the appropriate
insurer and shall take such other actions in accordance with the Servicing
Standard which are necessary under such Environmental Insurance Policy in order
to realize the full value thereof for the benefit of the Certificateholders. If
any other party hereto has actual knowledge of an Insured Environmental Event
with respect to any Mortgage Loan covered by an Environmental Insurance Policy
to this Agreement, such party shall promptly so notify the applicable Master
Servicer. Any legal fees, premiums or other out-of-pocket costs incurred in
accordance with the Servicing Standard in connection with any such claim under
an Environmental Insurance Policy shall be paid by the applicable Master
Servicer and shall be reimbursable to it as a Servicing Advance. With respect to
each Environmental Insurance Policy that relates to one or more Mortgage Loans
serviced by a Master Servicer, such Master Servicer shall review and familiarize
itself with the terms and conditions relating to enforcement of claims and shall
monitor the dates by which any claim must be made or any action must be taken
under such policy to realize the full value thereof for the benefit of the
Certificateholders in the event such Master Servicer has actual knowledge of an
Insured Environmental Event giving rise to a claim under such policy.

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

            (d) Each Master Servicer and each Special Servicer shall at all
times during the term of this Agreement (or, in the case of a Special Servicer,
at all times during the term of this Agreement during which Specially Serviced
Mortgage Loans or REO Properties as to which it is the applicable Special
Servicer exist as part of the Trust Fund) keep in force with a Qualified Insurer
having a financial strength or claims-paying rating no lower than two rating
categories below the highest rated Certificates outstanding, and in any event no
lower than "A" from S&P and "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 Master Servicer and each Special Servicer shall be deemed to have
complied with the foregoing provision if an Affiliate thereof has such fidelity
bond coverage and, by the terms of such fidelity bond, the coverage afforded
thereunder extends to the applicable Master Servicer or the applicable Special
Servicer, as the case may be. Such fidelity bond shall provide that it may not
be canceled without ten days' prior written notice to the Trustee.

            Each Master Servicer and each Special Servicer shall at all times
during the term of this Agreement (or, in the case of a Special Servicer, at all
times during the term of this Agreement during which Specially Serviced Mortgage
Loans and/or REO Properties as to which it is the applicable Special Servicer
exist as part of the Trust Fund) also keep in force with a Qualified Insurer
having a financial strength or claims-paying rating no lower than two rating
categories below the highest rated Certificates outstanding, and in any event no
lower than "A" from S&P and "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 Master Servicer and each Special
Servicer shall be deemed to have complied with the foregoing provisions if an
Affiliate thereof has such insurance and, by the terms of such policy or
policies, the coverage afforded thereunder extends to the applicable Master
Servicer or the applicable Special Servicer, as the case may be. Any such errors
and omissions policy shall provide that it may not be canceled without ten days'
prior written notice to the Trustee.

            Section 3.08  Enforcement of Alienation Clauses

            Each Master Servicer (with respect to Performing Mortgage Loans for
which it acts as Master Servicer) and each Special Servicer (with respect to
Specially Serviced Mortgage Loans for which it acts as Special Servicer), on
behalf of the Trustee as the mortgagee of record, shall enforce any
restrictions, contained in the related Mortgage or other related loan document
on transfers or further encumbrances of the related Mortgaged Property and on
transfers of interests in the related Borrower, unless the applicable Master
Servicer or the applicable Special Servicer, as the case may be, has 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 applicable Master
Servicer nor the applicable Special Servicer shall waive any right it has, or
grant any consent it is otherwise entitled to withhold, under any related
"due-on-sale" clause or "due-on-encumbrance" clause (other than with respect to
a Co-op Mortgage Loan as to which the NCBFSB Subordinate Debt Conditions have
been satisfied) 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, if (but only if) with respect to a
"due-on-sale" clause, such "due-on-sale" clause involves any Mortgage Loan that,
individually or together with all other Mortgage Loans, if any, that are in the
same Cross-Collateralized Group as such Mortgage Loan, has a Cut-off Date
Principal Balance in excess of $15,000,000 or 5% of the Initial Pool Balance or,
with respect to the enforcement of a "due-on-encumbrance" clause, such Mortgage
Loan or group of Cross-Collateralized Mortgage Loans: (i) is greater than 2% of
the Mortgage Pool balance, (ii) has an original principal balance that is one of
the ten highest original principal balances in the Mortgage Pool, (iii) has an
aggregate debt service coverage ratio less than 1.20x or (iv) has an aggregate
loan-to-value ratio greater than 85%; and provided, further, that a Master
Servicer shall not waive any right it has, or grant any consent it is otherwise
entitled to withhold under any "due-on-sale" or "due-on-encumbrance" clause
under any Mortgage Loan for which it acts as Master Servicer until it has
received the consent of the applicable Special Servicer (the giving of which
consent shall be subject to Section 3.24; and provided, further, that, subject
to the related Mortgage Loan Documents and applicable law, neither such Master
Servicer nor such Special Servicer shall waive any right it has, or grant any
consent it is otherwise entitled to withhold, under any related "due-on-sale" or
"due-on-encumbrance" clause under any Mortgage Loan (other than with respect to
a Co-op Mortgage Loan as to which the NCBFSB Subordinate Debt Conditions have
been satisfied), or approve the assumption of any Mortgage Loan, unless in any
such case, all associated costs and expenses are covered without any expense to
the Trust (it being understood and agreed that, except as expressly provided
herein, neither such Special Servicer nor such Master Servicer shall be
obligated to cover or assume any such costs or expenses); and provided, further,
that neither the applicable Master Servicer nor the applicable Special Servicer
shall (to the extent that it is within the control thereof to prohibit such
event) consent to the transfer of any Mortgaged Property which secures a
Cross-Collateralized Group unless (i) all of the Mortgaged Properties securing
such Cross-Collateralized Group are transferred simultaneously by the respective
Borrower or (ii) it obtains the consent of the Controlling Class Representative.
The applicable Master Servicer and the applicable Special Servicer shall each
provide the other and the Controlling Class Representative 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, each Master
Servicer (in the case of a Performing Mortgage Loan for which it acts as Master
Servicer) or each Special Servicer (in the case of a Specially Serviced Mortgage
Loan for which it acts Special Servicer) shall prepare all documents necessary
and appropriate for such purposes and shall coordinate with the related Borrower
for the due execution and delivery of such documents.

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

            If a Master Servicer or a Special Servicer collects an assumption
fee or an assumption application fee in connection with any transfer or proposed
transfer of any interest in a Borrower or a Mortgaged Property, then such Master
Servicer or such Special Servicer, as applicable, will apply that fee to cover
the costs and expenses associated with that transfer or proposed transfer that
are not otherwise paid by the related Borrower and that would otherwise be
payable or reimbursable out of the Trust Fund, including any Rating Agency fees
and expenses, to the extent such fees and expenses are collectible under the
related Mortgage Loan Document or applicable law. Any remaining portion of such
assumption fee (such remaining portion, a "Net Assumption Fee") or of such
assumption application fee (such remaining portion, a "Net Assumption
Application Fee") will be applied as additional compensation to the applicable
Master Servicer or the applicable Special Servicer in accordance with Section
3.11. Neither the applicable Master Servicer nor the applicable Special Servicer
shall waive any assumption fee or assumption application fee, to the extent it
would constitute additional compensation for the other such party, without the
consent of such other party.

            Section 3.09  Realization Upon Defaulted Mortgage Loans

            (a) Each Special Servicer shall, subject to Sections 3.09(b),
3.09(c), 3.09(d) 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
for which it acts as Special Servicer that comes into and continues in default
and as to which no satisfactory arrangements can be made for collection of
delinquent payments, including pursuant to Section 3.20; provided that the
applicable Master Servicer shall not, with respect to any ARD Mortgage Loan
after its Anticipated Repayment Date, take any enforcement action with respect
to the payment of Post-ARD Additional Interest (other than the making of
requests for its collection), and such Special Servicer may do so only if (i)
the taking of an enforcement action with respect to the payment of other amounts
due under such Mortgage Loan is, in the reasonable judgment of the Special
Servicer, and without regard to such Post-ARD Additional Interest, also
necessary, appropriate and consistent with the Servicing Standard or (ii) all
other amounts due under such Mortgage Loan have been paid, the payment of such
Post-ARD Additional Interest has not been forgiven in accordance with Section
3.20 and, in the reasonable judgment of the Special Servicer, the Liquidation
Proceeds expected to be recovered in connection with such enforcement action
will cover the anticipated costs of such enforcement action and, if applicable,
any associated Advance Interest. In connection with the foregoing, in the event
of a default under any Mortgage Loan or Cross-Collateralized Group that is
secured by real properties located in multiple states, and such states include
California or another state with a statute, rule or regulation comparable to
California's "one action rule," then the applicable Special Servicer shall
consult Independent counsel regarding the order and manner in which such Special
Servicer should foreclose upon or comparably proceed against such properties.
The reasonable costs of such consultation shall be paid by, and reimbursable to,
the applicable Master Servicer as a Servicing Advance. In addition, all other
costs and expenses incurred in any foreclosure sale or similar proceeding shall
be paid by, and reimbursable to, the applicable Master Servicer as a Servicing
Advance. Nothing contained in this Section 3.09 shall be construed so as to
require a Special Servicer, on behalf of the Trust, to make a bid on any
Mortgaged Property at a foreclosure sale or similar proceeding that is in excess
of the fair market value of such property, as determined by such Special
Servicer taking into account the factors described in Section 3.18 and the
results of any appraisal obtained pursuant to the following sentence or
otherwise, all such cash bids to be made in a manner consistent with the
Servicing Standard. If and when a Special Servicer deems it necessary in
accordance with the Servicing Standard for purposes of establishing the fair
market value of any Mortgaged Property securing a defaulted Mortgage Loan for
which it acts as Special Servicer, whether for purposes of bidding at
foreclosure or otherwise, such Special Servicer is authorized to have an
Appraisal completed with respect to such property (the cost of which appraisal
shall be paid by, and reimbursable to, the applicable Master Servicer as a
Servicing Advance). The applicable 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 any other provision of this Agreement, no
Mortgaged Property shall be acquired by a Special Servicer on behalf of the
Trust under such circumstances, in such manner or pursuant to such terms as
would (i) cause such Mortgaged Property to fail to qualify for purposes of
Section 860D(a) of the Code as "foreclosure property" within the meaning of
Section 860G(a)(8) of the Code (unless the portion of such REO Property that is
not treated as "foreclosure property" and that is held by the Lower-Tier REMIC
at any given time constitutes not more than a de minimis amount of the assets of
such Lower-Tier REMIC within the meaning of Treasury Regulations Section
1.860D-1(b)(3)(i) and (ii)), or (ii) except as permitted by Section 3.17(a),
subject the Trust to the imposition of any federal income or prohibited
transaction taxes under the Code. Subject to the foregoing, however, a Mortgaged
Property may be acquired through a single member limited liability company. In
addition, except as permitted under Section 3.17(a), a Special Servicer shall
not acquire any personal property on behalf of the Trust pursuant to this
Section 3.09 unless either:

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

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

            (c) Notwithstanding the foregoing provisions of this Section 3.09,
neither a Master Servicer nor a Special Servicer shall, on behalf of the Trust,
obtain title to a Mortgaged Property by foreclosure, deed in lieu of foreclosure
or otherwise, or take any other action with respect to any Mortgaged Property,
if, as a result of any such action, the Trustee, on behalf of the
Certificateholders (and, in the case of an A/B Loan Pair, the related B Loan
Holder) or any other specified person, could, in the reasonable judgment of the
applicable Special Servicer, exercised in accordance with the Servicing
Standard, be considered to hold title to, to be a "mortgagee-in-possession" of,
or to be an "owner" or "operator" of such Mortgaged Property within the meaning
of CERCLA or any comparable law, unless:

            (i) such Special Servicer has previously determined in accordance
      with the Servicing Standard, based on a Phase I Environmental Assessment
      (and any additional environmental testing that the Special Servicer deems
      necessary and prudent) of such Mortgaged Property conducted by an
      Independent Person who regularly conducts Phase I Environmental
      Assessments and performed during the 12-month period preceding any such
      acquisition of title or other action, that (x) the Mortgaged Property is
      in compliance with applicable environmental laws and regulations and (y)
      there are no circumstances or conditions present at the Mortgaged Property
      relating to the use, management or disposal of Hazardous Materials for
      which investigation, testing, monitoring, containment, clean-up or
      remediation could be required under any applicable environmental laws and
      regulations; or

            (ii) in the event that the determination described in clause (c)(i)
      above cannot be made, such Special Servicer has previously determined in
      accordance with the Servicing Standard, on the same basis as described in
      clause (c)(i) above, and taking into account the coverage provided under
      the related Environmental Insurance Policy, that it would maximize the
      recovery to the Certificateholders (and the B Loan Holder if in connection
      with a B Loan, taken as a collective whole) on a present value basis (the
      relevant discounting of anticipated collections that will be distributable
      to Certificateholders to be performed at the related Net Mortgage Rate) to
      acquire title to or possession of the Mortgaged Property and to take such
      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)(y) above.

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

            (d) If neither of the conditions set forth in clauses (i) and (ii)
of the first paragraph of Section 3.09(c) has been satisfied with respect to any
Mortgaged Property securing a defaulted Mortgage Loan, the applicable Special
Servicer shall take such action as is in accordance with the Servicing Standard
(other than proceeding against the Mortgaged Property) and, at such time as it
deems appropriate, may, on behalf of the Trust, release all or a portion of such
Mortgaged Property from the lien of the related Mortgage.

            (e) Each Special Servicer shall report to the Trustee, the
applicable Master Servicer and the Controlling Class Representative monthly in
writing as to any actions taken by such Special Servicer with respect to any
Mortgaged Property as to which neither of the conditions set forth in clauses
(i) and (ii) of the first paragraph of Section 3.09(c) has been satisfied, in
each case until the earliest to occur of satisfaction of either of such
conditions, release of the lien of the related Mortgage on such Mortgaged
Property and the related Mortgage Loan's becoming a Corrected Mortgaged Loan.

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

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

            (h) Within three Business Days from the date on which a Special
Servicer makes a Final Recovery Determination with respect to any Mortgage Loan
for which it acts as Special Servicer or related REO Property, it shall deliver
to the Trustee, the applicable Master Servicer and the Controlling Class
Representative an Officer's Certificate evidencing such determination. Each
Special Servicer shall maintain accurate records, prepared by a Servicing
Officer, of each such Final Recovery Determination (if any) and the basis
thereof.

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

            (b) If from time to time, and as appropriate for servicing or
foreclosure of any Mortgage Loan, a Master Servicer or a Special Servicer shall
otherwise require any Mortgage File (or any portion thereof), then, upon request
of the applicable Master Servicer and receipt from such Master Servicer of a
Request for Release in the form of Exhibit D-1 attached hereto signed by a
Servicing Officer thereof, or upon request of the applicable Special Servicer
and receipt from such Special Servicer of a Request for Release in the form of
Exhibit D-2 attached hereto, the Trustee shall release, or cause any related
Custodian to release, such Mortgage File (or portion thereof) to the applicable
Master Servicer or the applicable 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 applicable 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 a Collection Account or an
A/B Loan Pair Custodial Account pursuant to Section 3.04(a) 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 applicable
Master Servicer or the applicable Special Servicer, as applicable.

            (c) Within five Business Days of a Special Servicer's request
therefor (or, if such Special Servicer notifies the Trustee of an exigency,
within such shorter period as is reasonable under the circumstances), the
Trustee shall execute and deliver to such Special Servicer, in the form supplied
to the Trustee by such Special Servicer, any court pleadings, requests for
trustee's sale or other documents reasonably necessary to the foreclosure or
trustee's sale in respect of a Mortgaged Property or to any legal action brought
to obtain judgment against any Borrower on the Mortgage Note or Mortgage or to
obtain a deficiency judgment, or to enforce any other remedies or rights
provided by the Mortgage Note or Mortgage or otherwise available at law or in
equity or to defend any legal action or counterclaim filed against the Trust,
the applicable Master Servicer or the applicable Special Servicer; provided that
the Trustee may alternatively execute and deliver to the applicable Special
Servicer, in the form supplied to the Trustee by such Special Servicer, a
limited power of attorney issued in favor of such Special Servicer and
empowering such Special Servicer to execute and deliver any or all of such
pleadings or documents on behalf of the Trustee (however, the Trustee shall not
be liable for any misuse of such power of attorney by such Special Servicer).
Together with such pleadings or documents (or such power of attorney empowering
such Special Servicer to execute the same on behalf of the Trustee), the
applicable Special Servicer shall deliver to the Trustee an Officer's
Certificate requesting that such pleadings or documents (or such power of
attorney empowering such Special Servicer to execute the same on behalf of the
Trustee) be executed by the Trustee and certifying as to the reason such
pleadings or documents are required and that the execution and delivery thereof
by the Trustee (or by such Special Servicer on behalf of the Trustee) will not
invalidate or otherwise affect the lien of the Mortgage, except for the
termination of such a lien upon completion of the foreclosure or trustee's sale.

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

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

            (a) As compensation for its activities hereunder, each Master
Servicer shall be entitled to receive the Master Servicing Fee with respect to
each Mortgage Loan and each REO Mortgage Loan for which it acts as Master
Servicer. As to each such Mortgage Loan and REO Mortgage Loan, for each calendar
month (commencing with March 2003) or any applicable portion thereof, the Master
Servicing Fee shall accrue at the related Master Servicing Fee Rate on the same
principal amount as interest accrues from time to time during such calendar
month (or portion thereof) on such Mortgage Loan or is deemed to accrue from
time to time during such calendar month (or portion thereof) on such REO
Mortgage Loan, as the case may be, and shall be calculated on the same Interest
Accrual Basis as is applicable for such Mortgage Loan or REO Mortgage Loan, as
the case may be. The Master Servicing Fee with respect to any Mortgage Loan or
REO Mortgage Loan shall cease to accrue if a Liquidation Event occurs in respect
thereof. Master Servicing Fees earned with respect to any Mortgage Loan or REO
Mortgage Loan shall be payable monthly from payments of interest on such
Mortgage Loan or REO Revenues allocable as interest on such REO Mortgage Loan,
as the case may be. Each Master Servicer shall be entitled to recover unpaid
Master Servicing Fees in respect of any Mortgage Loan or REO Mortgage Loan for
which it acts as Master Servicer out of the portion any related Insurance
Proceeds, Condemnation Proceeds or Liquidation Proceeds allocable as interest on
such Mortgage Loan or REO Mortgage Loan, as the case may be.

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

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

            (b) Subject to offset as provided in Section 3.02(a), each Master
Servicer shall be entitled to receive the following items as additional
servicing compensation with respect to the Mortgage Loans for which it acts as
Master Servicer (the following items, collectively, "Additional Master Servicing
Compensation"):

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

            (ii) 50% of any and all Net Assumption Application Fees, Net
      Assumption Fees, modification fees, extension fees, consent fees, waiver
      fees 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 and defeasance fees
      collected on the Mortgage Loans; and

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

            The Master Servicers shall not be entitled to any Master Servicing
Fees or any other compensation from the Trust Fund hereunder with respect to the
B Loans

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

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

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

            As further compensation for its activities hereunder, each Special
Servicer shall also be entitled to receive a Liquidation Fee with respect to
each Specially Serviced Mortgage Loan with respect to which it acts as Special
Servicer or REO Property related thereto as to which it receives any full,
partial or discounted payoff from the related Borrower or any Condemnation
Proceeds or Liquidation Proceeds (other than any Specially Serviced Mortgage
Loan or REO Property that is (i) purchased by the Special Servicer or any
Holders of Certificate(s) of a Controlling Class or any assignee of the
foregoing pursuant to Section 3.18; provided that if any such party assigns
their Purchase Option to an unaffiliated third party without any consideration
therefor (other than nominal consideration), a Liquidation Fee shall be payable
pursuant to Section 3.11, (ii) purchased by a Master Servicer, a Special
Servicer or any Certificateholder(s) of the Controlling Class pursuant to
Section 9.01, (iii) acquired by the Sole Certificateholder(s) in exchange for
all the Certificates pursuant to Section 9.01, (iv) purchased by the related B
Loan Holder pursuant to the related A/B Intercreditor Agreement so long as such
Specially Serviced Mortgage Loan or REO Property is purchased within the time
period specified in such related A/B Intercreditor Agreement or (v) repurchased
or replaced no later than the end of the applicable Initial Resolution Period
and any applicable Resolution Extension Period, as a result of a Material Breach
or a Material Document Defect, by a Mortgage Loan Seller pursuant to the related
Mortgage Loan Purchase Agreement or by the Column Performance Guarantor pursuant
to the Column Performance Guarantee). Notwithstanding anything to the contrary
described above, no Liquidation Fee will be payable based on, or out of,
Liquidation Proceeds received in connection with the purchase of any A Loan by
the related B Loan Holder pursuant to the related A/B Intercreditor Agreement
(within the time frame therein specified). 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 Liquidation Expenses and Default
Charges). The Liquidation Fee with respect to any such Specially Serviced
Mortgage Loan will not be payable if such Mortgage Loan becomes a Corrected
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 Mortgage Loan or REO Property described in the parenthetical to the
first sentence of this paragraph.

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

            (d) Subject to offset as provided in Section 3.02(a), each Special
Servicer shall be entitled to receive the following items as additional special
servicing compensation with respect to the Specially Serviced Mortgage Loans or
REO Mortgage Loans and Performing Mortgage Loans for which it acts as Special
Servicer (the following items, collectively, the "Additional Special Servicing
Compensation"):

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

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

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

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

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

            To the extent that any of the amounts described in the preceding
paragraph are collected by a Master Servicer with respect to Specially Serviced
Mortgage Loans, such Master Servicer shall promptly pay such amounts to the
applicable Special Servicer and shall not be required to deposit such amounts in
its Collection Account pursuant to Section 3.04(a).

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

            (f) If a Master Servicer or a Special Servicer is required under
this Agreement to make a Servicing Advance, but neither does so within ten days
after such Advance is required to be made, the Trustee shall, if it has actual
knowledge of such failure on the part of the applicable Master Servicer or the
applicable Special Servicer, as the case may be, give notice of such failure to
the defaulting party. If such Advance is not made by such Master Servicer or
such Special Servicer within three Business Days after such notice, then
(subject to Section 3.11(h) below) the Trustee or a Fiscal Agent appointed
thereby shall make such Advance. If any Fiscal Agent makes any such Servicing
Advance, the Trustee shall be deemed not to be in default under this Agreement
for failing to do so.

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

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

            (i) Notwithstanding anything to the contrary set forth herein, each
Master Servicer may (and, at the direction of the applicable Special Servicer if
a Specially Serviced Mortgage Loan or an REO Property is involved, shall) pay
directly out of its Collection Account, but only as and to the extent
contemplated by Section 3.05(a), any servicing expense that, if paid by such
Master Servicer or the applicable Special Servicer, would constitute a
Nonrecoverable Servicing Advance; provided that such Master Servicer (or the
applicable Special Servicer, if a Specially Serviced Mortgage Loan or an REO
Property is involved) has determined in accordance with the Servicing Standard
that making such payment is in the best interests of the Certificateholders (as
a collective whole), as evidenced by an Officer's Certificate delivered promptly
to the Depositor, the Trustee and the Controlling Class Representative, setting
forth the basis for such determination and accompanied by any information that
such Person may have obtained that supports such determination. A copy of any
such Officer's Certificate (and accompanying information) of a Master Servicer
shall also be delivered promptly to the applicable Special Servicer, and a copy
of any such Officer's Certificate (and accompanying information) of a Special
Servicer shall also be promptly delivered to the applicable Master Servicer.
Section

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

            (a) The applicable Special Servicer shall perform or cause to be
performed a physical inspection of a Mortgaged Property as soon as practicable
(but in any event not later than 60 days) after the related Mortgage Loan
becomes a Specially Serviced Mortgage Loan (and, in cases where the related
Mortgage Loan has become a Specially Serviced Mortgage Loan, such Special
Servicer shall continue to perform or cause to be performed a physical
inspection of the subject Mortgaged Property at least once per calendar year
thereafter for so long as the related Mortgage Loan remains a Specially Serviced
Mortgage Loan or if such Mortgaged Property becomes an REO Property); provided
that such Special Servicer shall be entitled to reimbursement of the reasonable
and direct out-of-pocket expenses incurred by it in connection with each such
inspection as Servicing Advances. Beginning in 2003, the applicable 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, in the case of each
Mortgage Loan with an unpaid principal balance of under $2,000,000, once every
two years), if the applicable Special Servicer has not already done so during
that period pursuant to the preceding sentence. Each Master Servicer and each
Special Servicer shall prepare (and, promptly following preparation deliver to
the Controlling Class Representative and, with respect to a Special Servicer, to
the applicable Master Servicer; provided, that with respect to Performing Co-op
Mortgage Loans, such report shall be delivered to the Controlling Class
Representative in an electronic format, exclusive of photographs that are part
of such report, until such time as the Co-op Master Servicer or Co-op Special
Servicer, as the case may be, has established a website where such photographs
can be viewed, provided, further, however, that such report, complete with
photographs, shall be delivered to the Controlling Class Representative upon
request) a written report of each such inspection performed by it or on its
behalf that sets forth in detail the condition of the Mortgaged Property and
that specifies the occurrence or existence of: (i) any sale, transfer or
abandonment of the Mortgaged Property of which such Master Servicer or Special
Servicer, as applicable, is aware, (ii) any change in the condition or occupancy
of the Mortgaged Property of which such Master Servicer or Special Servicer, as
applicable, in accordance with the Servicing Standard, is aware and that it
considers material, or (iii) any waste committed on the Mortgaged Property of
which such Master Servicer or Special Servicer, as the case may be, in
accordance with the Servicing Standard, is aware and that it considers material.
Each Master Servicer and each Special Servicer shall deliver to the Trustee,
upon written request, and the Controlling Class Representative, a copy (or image
in suitable electronic media) of each such written report prepared by it
(provided, that with respect to Performing Co-op Mortgage Loans, such report
shall be delivered to the Controlling Class Representative in an electronic
format, exclusive of photographs that are part of such report, until such time
as the Co-op Master Servicer or Co-op Special Servicer, as the case may be, has
established a website where such photographs can be viewed, provided, further,
however, that such report, complete with photographs, shall be delivered to the
Controlling Class Representative upon request), within 30 days following the
later of completion of the related inspection if the inspection is performed by
such Master Servicer or Special Servicer, as applicable, or receipt of the
related inspection report if the inspection is performed by a third-party. Upon
request, the Trustee shall request from such Master Servicer or Special
Servicer, as applicable, and, to the extent such items have been delivered to
the Trustee, upon written request, by such Master Servicer or Special Servicer,
as applicable, deliver to each of the Depositor, the related Mortgage Loan
Seller, 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 a Master Servicer or a Special Servicer.

            (b) Commencing with respect to the calendar quarter ended March 31,
2003, the applicable Special Servicer, in the case of any Specially Serviced
Mortgage Loan, and the General Master Servicer, in the case of each Performing
Mortgage Loan that is a General Mortgage Loan, 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; provided that in the case of Performing Mortgage Loans that are Co-op
Mortgage Loans, the Co-op Master Servicer shall use reasonable efforts to
collect annual financial statements whether or not expressly required by the
related loan documents and, to the extent expressly required by the related loan
documents, shall use reasonable efforts to collect quarterly financial
statements and annual or quarterly operating statements. In addition, the
applicable Special Servicer shall cause quarterly and annual operating
statements, budgets and rent rolls (except with respect to Co-op Mortgage Loans)
to be regularly prepared in respect of each REO Property and shall collect all
such items promptly following their preparation. Each Special Servicer shall
deliver copies (or images in suitable electronic media) of all of the foregoing
items so collected or obtained by it to the applicable Master Servicer, the
Trustee and the Controlling Class Representative within 30 days of its receipt
thereof.

            Each Master Servicer shall maintain a CMSA Operating Statement
Analysis Report with respect to each Mortgaged Property and REO Property related
to each Mortgage Loan for which it acts as Master Servicer. Within 60 days after
receipt by a Master Servicer from the related Borrower or otherwise, as to a
Performing Mortgage Loan for which it acts as Master Servicer, and within 30
days after receipt by a Master Servicer from the applicable Special Servicer or
otherwise, as to a Specially Serviced Mortgage Loan and REO Property for which
it acts as Master Servicer, of any annual operating statements or rent rolls
(except with respect to Co-op Mortgage Loans) with respect to any Mortgaged
Property or REO Property, such Master Servicer shall, based upon such operating
statements or rent rolls (except with respect to Co-op Mortgage Loans), prepare
(or, if previously prepared, update) the CMSA Operating Statement Analysis
Report for the subject Mortgaged Property or REO Property. Each Master Servicer
shall remit a copy of each CMSA Operating Statement Analysis Report prepared or
updated by it (promptly following initial preparation and each update thereof),
together with, if so requested and not already provided pursuant to the
preceding paragraph, the underlying operating statements and rent rolls (except
with respect to Co-op Mortgage Loans), to the Trustee, the applicable Special
Servicer and the Controlling Class Representative. All CMSA Operating Statement
Analysis Reports shall be maintained by the applicable Master Servicer with
respect to each Mortgaged Property and REO Property related to a Mortgage Loan
for which it acts as Master Servicer. The Trustee shall, upon request, request
from a Master Servicer (if necessary) and, to the extent such items have been
delivered to the Trustee by such 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 such CMSA Operating Statement Analysis
(or update thereof) and, if requested, the related operating statement or rent
rolls (except with respect to Co-op Mortgage Loans).

            Within 60 days (or, in the case of items received from a Special
Servicer with respect to Specially Serviced Mortgage Loans and REO Properties
for which it acts as Special Servicer, 30 days) after receipt by a Master
Servicer of any quarterly or annual operating statements with respect to any
Mortgaged Property or REO Property, such Master Servicer shall prepare or update
and forward to the Trustee, the applicable Special Servicer and the Controlling
Class Representative (in an electronic format reasonably acceptable to the
Trustee and such 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.

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

            (c) Not later than 4:00 p.m. (New York City time) on each
Determination Date, each Special Servicer shall prepare and deliver or cause to
be delivered to the applicable Master Servicer, the Controlling Class
Representative and shall contemporaneously provide a copy of such materials as
they relate to an A Loan to the B Loan Holder the following reports (or data
files relating to reports of the applicable Master Servicer) with respect to the
Specially Serviced Mortgage Loans serviced by such Special Servicer and any
related 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 Mortgage
Loan by loan number and property name). At or before 4:00 p.m. (New York City
time) on each Determination Date, such Special Servicer shall prepare and
deliver or cause to be delivered to the applicable Master Servicer the following
reports or the related data fields reflected in the reports reasonably requested
with respect to the Specially Serviced Mortgage Loans and any REO Properties,
providing the information required of such Special Servicer pursuant to Section
3.12(e) 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 Report; and (v) a
CMSA REO Status Report. In addition, each Special Servicer shall from time to
time provide the applicable Master Servicer with such information in such
Special Servicer's possession regarding the Specially Serviced Mortgage Loans
for which it acts as Special Servicer and related REO Properties as may be
requested by the applicable Master Servicer and is reasonably necessary for such
Master Servicer to prepare each report and any supplemental information required
to be provided by such Master Servicer to the Trustee.

            (d) Not later than 3:00 p.m. (New York City time) on the second
Business Day following each Determination Date, each Master Servicer shall
prepare (if and to the extent necessary) and deliver or cause to be delivered to
the Trustee (and shall contemporaneously provide a copy of such materials and
related reports as they relate to an A Loan to the B Loan Holder), in a
computer-readable medium downloadable by the Trustee, each of the files and
reports comprising the CMSA Investor Reporting Package (excluding any CMSA
Operating Statement Analysis Report, any CMSA NOI Adjustment Worksheet, the CMSA
Bond Level File, the CMSA Collateral Summary File and the CMSA Loan Setup File),
in each case providing the most recent information with respect to the Mortgage
Loans and REO Properties for which it acts as Master Servicer as of the related
Determination Date (and which, in each case, if applicable, will identify each
subject Mortgage Loan by loan number and property name); provided that such
Master Servicer shall not be required to prepare and deliver any of the files
and reports comprising the CMSA Investor Reporting Package (other than the CMSA
Loan Periodic Update File) before the second Business Day following the third
Determination Date following the Closing Date.

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

            (e) Each Special Servicer shall deliver to the applicable Master
Servicer the reports set forth in Section 3.12(b) and Section 3.12(c), and the
applicable Master Servicer shall deliver to the Trustee the reports set forth in
Section 3.12(d), in an electronic format reasonably acceptable to such Special
Servicer, the applicable Master Servicer and the Trustee. A Master Servicer may,
absent manifest error, conclusively rely on the reports to be provided by a
Special Servicer pursuant to Section 3.12(b) and Section 3.12(c). The Trustee
may, absent manifest error, conclusively rely on the reports to be provided by a
Master Servicer pursuant to Section 3.12(d). In the case of information or
reports to be furnished by a 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 a Special Servicer pursuant to Section
3.12(b) or Section 3.12(c) and to the extent that such reports are to be
prepared and delivered by a Special Servicer pursuant to Section 3.12(b) or
Section 3.12(c), such 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 applicable Special Servicer, and such 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 applicable 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 a Master
Servicer or Special Servicer to disclose any information otherwise required to
be disclosed by this Section 3.12 shall not constitute a breach of this Section
3.12 to the extent such Master Servicer or Special Servicer so fails because
such disclosure, in the reasonable belief of such Master Servicer or Special
Servicer as the case may be, would violate any applicable law or any provision
of a Mortgage Loan Document prohibiting disclosure of information with respect
to the Mortgage Loans or Mortgaged Properties or would constitute a waiver of
the attorney-client privilege on behalf of the Trust. The Master Servicers and
Special Servicers may disclose any such information or any additional
information to any Person so long as such disclosure is consistent with
applicable law, the related Mortgage Loan Documents and the Servicing Standard.
A Master Servicer or a Special Servicer may affix to any information provided by
it any disclaimer it deems appropriate in its reasonable discretion (without
suggesting liability on the part of any other party hereto).

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

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

            (i) The reporting obligations of the applicable Master Servicer in
connection with an A Loan shall be construed to require such Master Servicer to
provide information regarding the related A Note only, but whenever such Master
Servicer remits funds to the B Loan Holder, it shall thereupon deliver to such
holder a remittance report identifying the amounts in such remittance. The
applicable Master Servicer shall contemporaneously with any related delivery to
the Trustee or the applicable Special Servicer, as applicable, provide any such
reports which contain information related to the related Mortgaged Property or
financial information regarding the borrower to the B Loan Holder. The
applicable Master Servicer shall, with the reasonable cooperation of the other
parties hereto, deliver to each B Loan Holder all documents, statements, reports
and information with respect to the related B Loan and/or the related Mortgaged
Property as may be required under the related A/B Intercreditor Agreement.

            Section 3.13 Annual Statement as to Compliance

            Each Master Servicer and each Special Servicer shall deliver to the
Trustee, the Depositor, the Underwriters, the Controlling Class Representative
and each other, on or before March 31 of each year, beginning in 2004, an
Officer's Certificate (the "Annual Performance Certification") stating, as to
the signer thereof, that (i) a review of the activities of such Master Servicer
or such Special Servicer, as the case may be, during the preceding calendar year
and of its performance under this Agreement has been made under such officer's
supervision, (ii) to the best of such officer's knowledge, based on such review,
such Master Servicer or such Special Servicer, as the case may be, has fulfilled
all of its obligations under this Agreement in all material respects throughout
such year (or, if there has been a default in the fulfillment of any such
obligation, specifying each such default known to such officer and the nature
and status thereof), and (iii) such Master Servicer or such Special Servicer, as
the case may be, has received no notice regarding the qualification, or
challenging the status, of the Upper-Tier REMIC or the Lower-Tier REMIC as a
REMIC or the Grantor Trust as a grantor trust from the IRS or any other
governmental agency or body (or, if it has received any such notice, specifying
the details thereof); provided that each Master Servicer and each Special
Servicer shall be required to deliver its Annual Performance Certification by
March 20 in 2004 or any given year thereafter if it has received written
confirmation from the Trustee or the Depositor by January 31 of that year that a
Report on Form 10-K is required to be filed in respect of the Trust for the
preceding calendar year.

            Section 3.14 Reports by Independent Public Accountants

            On or before March 31 of each year, beginning in 2004, each Master
Servicer and each Special Servicer at its expense shall cause a firm of
independent public accountants that is a member of the American Institute of
Certified Public Accountants to furnish a statement (the "Annual Accountants'
Report") to the Trustee, the Depositor, the Underwriters, the Controlling Class
Representative and each other, to the effect that such firm has examined the
servicing operations of such Master Servicer or such Special Servicer, as the
case may be, for the previous calendar year and that, on the basis of such
examination, conducted substantially in compliance with USAP or the Audit
Program, as applicable, such firm confirms that such Master Servicer or such
Special Servicer, as the case may be, has complied during such previous calendar
year with the minimum servicing standards (to the extent applicable to
commercial and multifamily mortgage loans) identified in USAP or the Audit
Program, as applicable, in all material respects, except for such significant
exceptions or errors in records that, in the opinion of such firm, USAP or the
Audit Program, as applicable, requires it to report; provided that such Master
Servicer and such Special Servicer shall each be required to cause the delivery
of its Annual Accountants' Report by March 20 in 2004 or any given year
thereafter if it has received written confirmation from the Trustee or the
Depositor by January 31 of that year that a Report on Form 10-K is required to
be filed in respect of the Trust for the preceding calendar year. In rendering
its report such firm may rely, as to matters relating to the direct servicing of
securitized commercial and multifamily mortgage loans by sub-servicers, upon
comparable reports of firms of independent certified public accountants rendered
on the basis of examinations conducted in accordance with the same standards
(rendered within one year of such report) with respect to those sub-servicers.

            Each Master Servicer and each Special Servicer will 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 Master Servicer and each Special Servicer shall afford to
the Trustee, any Fiscal Agent, the Depositor, each Rating Agency, the
Controlling Class Representative and to the OTS, the FDIC and any other banking
or insurance regulatory authority that may exercise authority over any
Certificateholder or Certificate Owner, access to any records regarding the
Mortgage Loans and the servicing thereof within its control, except to the
extent it is prohibited from doing so by applicable law, the terms of the
Mortgage Loan Documents or contract entered into prior to the Closing Date or to
the extent such information is subject to a privilege under applicable law to be
asserted on behalf of the Certificateholders. Such access shall be afforded
without charge but only upon reasonable prior written request and during normal
business hours at the offices of such Master Servicer or such Special Servicer,
as the case may be, designated by it. Each Master Servicer and each Special
Servicer shall each be entitled to 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, each
Master Servicer and each Special Servicer may require registration (to the
extent access is provided via a Master Servicer's Internet Website) and the
acceptance of a reasonable and customary disclaimer and otherwise adopt
reasonable rules and procedures, which may include, to the extent a Master
Servicer or a Special Servicer, as applicable, deems necessary or appropriate,
conditioning access on the execution and delivery of an agreement governing the
availability, use and disclosure of such information.

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

            (c) On a monthly basis at a time mutually agreed upon by the
Controlling Class Representative and the applicable Master Servicer or the
applicable Special Servicer, each Master Servicer and each Special Servicer
shall, without charge, make a knowledgeable Servicing Officer available, at the
option of such Controlling Class Representative either by telephone or at the
office of such Servicing Officer, to answer questions from such Controlling
Class Representative regarding the performance and servicing of the Mortgage
Loans in and/or REO Properties for which such Master Servicer or 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 (and on behalf of the related B Loan Holder if such REO
Property is related to an A/B Loan Pair) or, subject to Section 3.09(b), to a
single member limited liability company of which the Trust is the sole member,
which limited liability company is formed or caused to be formed by the Special
Servicer at the expense of the Trust for the purpose of taking title to one or
more REO Properties pursuant to this Agreement. The limited liability company
shall be a manager-managed limited liability company, with the Special Servicer
to serve as the initial manager to manage the property of the limited liability
company, including any applicable REO Property, in accordance with the terms of
this Agreement as if such property was held directly in the name of the Trust or
Trustee under this Agreement (and for the benefit of the related B Loan Holder
if such REO Property is related to an A/B Loan Pair). The Special Servicer, on
behalf of the Trust (and for the benefit of the related B Loan Holder if such
REO Property is related to an A/B Loan Pair), shall sell any REO Property in
accordance with Section 3.18(d) and, in any event, 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 either Trust REMIC or an Adverse Grantor Trust Event with
respect to the Grantor Trust. 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 such 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, the Special Servicer shall (i) promptly forward a copy of such REO
Extension or Opinion of Counsel to the Trustee, and (ii) sell such REO Property
within such extended period as is permitted by such REO Extension or
contemplated by such Opinion of Counsel, as the case may be. Any expense
incurred by 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 paid by and reimbursable to the Master
Servicer as a Servicing Advance.

            (b) The Special Servicer shall segregate and hold all funds
collected and received in connection with any REO Property separate and apart
from its own funds and general assets. If an REO Acquisition shall occur, the
Special Servicer shall establish and maintain one or more accounts
(collectively, the "REO Account"), to be held on behalf of the Trustee (as
holder of the Uncertificated Lower-Tier Interests) in trust for the benefit of
the Certificateholders (and on behalf of the related B Loan Holder if such REO
Property is related to an A/B Loan Pair), for the retention of revenues and
other proceeds derived from each REO Property. Each account that constitutes the
REO Account shall be an Eligible Account. The Special Servicer shall deposit, or
cause to be deposited, in the REO Account, within two Business Days 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 Collection Period).
The Special Servicer shall give notice to the other parties hereto of the
location of the REO Account when first established and of the new location of
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. Within two Business Days
following the end of each Collection Period, the Special Servicer shall withdraw
from the REO Account and deposit into the Collection Account (or, if the subject
REO Property relates to an A/B Loan Pair, into the related A/B Loan Pair
Custodial Account) or deliver to the Master Servicer (which shall deposit such
amounts into the Collection Account) (or, if the subject REO Property relates to
an A/B Loan Pair, into the related A/B Loan Pair Custodial Account) the
aggregate of all amounts received in respect of each REO Property during such
Collection Period, net of any withdrawals made out of such amounts pursuant to
the preceding sentence and Section 3.17 below; provided that 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 the
related REO Property (including the creation of a reasonable reserve for
repairs, replacements, necessary capital improvements and other related
expenses), such reserve not to exceed an amount sufficient to cover such items
reasonably expected to be incurred during the following 12-month period.

            (d) The Special Servicer shall keep and maintain separate records,
on a property-by-property basis, for the purpose of accounting for all deposits
to, and withdrawals from, the REO Account pursuant to Section 3.16(b) or
3.16(c).

            Section 3.17 Management of REO Property

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

          (i) None of the income from Directly Operating such Mortgaged Property
     would be subject to tax as "net income from foreclosure property" within
     the meaning of the REMIC Provisions (either such tax referred to herein as
     an "REO Tax"), such Mortgaged Property may be Directly Operated (other than
     holding such REO Property primarily for sale to customers (other than the
     sale of REO Property pursuant to Section 3.18), or the performance of any
     construction work thereon) by such 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 such Special
     Servicer may (provided that in the judgment of such Special Servicer,
     exercised in accordance with the Servicing Standard, it is commercially
     reasonable) so lease or otherwise operate such REO Property; or

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

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

            (b) If title to any REO Property is acquired, the applicable Special
Servicer shall manage, conserve, protect and operate such REO Property for the
benefit of the Certificateholders (and for the benefit of the holder of the B
Loan Holder if such REO Property is related to an A/B Loan Pair) solely for the
purpose of its prompt disposition and sale in accordance with Section 3.18, in a
manner that does not cause such REO Property to fail to qualify as "foreclosure
property" within the meaning of Section 860G(a)(8) of the Code for purposes of
Section 860D(a) of the Code or, except as contemplated by Section 3.17(a),
result in the receipt by either Trust REMIC of any "income from non-permitted
assets" within the meaning of Section 860F(a)(2)(B) of the Code, in an Adverse
REMIC Event with respect to any Trust REMIC or in an Adverse Grantor Trust Event
with respect to the Grantor Trust. Except as contemplated by Section 3.17(a),
the applicable Special Servicer shall not enter into any lease, contract or
other agreement that causes the Trust to receive, and (unless required to do so
under any lease, contract or agreement to which such 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 a Mortgage Loan) shall not cause or allow the Trust to
receive, any "net income from foreclosure property" that is subject to taxation
under the REMIC Provisions. Furthermore, such Special Servicer may not, on
behalf of the Trust, directly or through any agents, make any significant
operating decisions with respect to such REO Property that address matters other
than those consistent with the normal course of business, complete any
significant construction on such REO Property or provide vendor financing for
the sale of such REO Property. Subject to the foregoing, however, the applicable
Special Servicer shall have full power and authority to do any and all things in
connection therewith as are consistent with the Servicing Standard and,
consistent therewith, shall withdraw from the REO Account, to the extent of
amounts on deposit therein with respect to any REO Property, funds necessary for
the proper 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 applicable Master
Servicer shall, at the direction of the applicable Special Servicer, make a
Servicing Advance of such amounts as are necessary for such purposes unless such
Master Servicer or such Special Servicer determines, in its reasonable judgment,
that such advances would, if made, be Nonrecoverable Servicing Advances;
provided, however, that such Master Servicer may in its sole discretion make any
such Servicing Advance without regard to recoverability (and be reimbursed for
such Advance as a Nonrecoverable Advance) if it is a necessary fee or expense
incurred in connection with the defense or prosecution of legal proceedings.

            (c) A Special Servicer may, and if so required for any REO Property
to qualify or remain qualified as "foreclosure property" within the meaning of
Section 860G(a)(8), shall contract with any Independent Contractor for the
operation and management of any REO Property related to a Mortgage Loan for
which it acts as Special Servicer, provided that:

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

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

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

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

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

            A Special Servicer shall be entitled to enter into any agreement
with any Independent Contractor performing services for it related to its duties
and obligations hereunder for indemnification of such Special Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification. To the extent the costs of any contract with any
Independent Contractor for the operation and management of any REO Property are
greater that the revenues available from such property, such excess costs shall
be paid by and reimbursable to the applicable Master Servicer as a Servicing
Advance.

            Section 3.18 Fair Value Option; Sale of REO Properties

            (a) The parties hereto may sell or purchase, or permit the sale or
purchase of, a Mortgage Loan or REO Property only on the terms and subject to
the conditions set forth in this Section 3.18 or as otherwise expressly provided
in or contemplated by Section 2.03 and Section 9.01 of this Agreement; the
Mortgage Loan Purchase Agreement; the Column Performance Guarantee; the related
Mortgage Loan Documents and/or, in the case of an A Loan, the related A/B
Intercreditor Agreement.

            (b) If any Mortgage Loan becomes a Specially Designated Defaulted
Mortgage Loan, then the applicable Special Servicer shall so notify the Trustee,
the Controlling Class Representative and the applicable Master Servicer, and the
Trustee shall, in turn, notify the Holder(s) of the Controlling Class in
writing. In addition, such Special Servicer shall determine (in accordance with
the Servicing Standard, taking into account the considerations contemplated by
the following paragraph, but without regard to the Purchase Option provided for
in Section 3.18(c) below), and report to the Trustee and the applicable Master
Servicer, the Fair Value of such Mortgage Loan; provided, however, in connection
with the sale of a Specially Designated Defaulted A Loan, none of the Trustee,
Master Servicers, Special Servicers or Directing Certificateholder will provide
the B Loan Holder with the Fair Value. The applicable Special Servicer's
determination of the Fair Value of any Specially Designated Defaulted Mortgage
Loan shall be made as soon as reasonably practicable, but in no event later than
20 days after the applicable Special Servicer receives the requisite Appraisal
or any other third-party reports that it deems necessary to make the
determination. If at any time the applicable Special Servicer becomes aware of
any circumstances or conditions that have occurred or arisen with respect to any
Specially Designated Defaulted Mortgage Loan or the related Mortgaged Property
subsequent to, and that would, in such Special Servicer's reasonable judgment,
materially affect, such Special Servicer's most recent Fair Value determination
with respect to such Specially Designated Defaulted Mortgage Loan, then such
Special Servicer shall redetermine (in the same manner as provided above, but
taking into account such new circumstances or conditions known to such Special
Servicer), and report to the Trustee, the Controlling Class Representative and
the applicable Master Servicer (and the Trustee shall, in turn, report to the
Holder(s) of the Controlling Class), the updated Fair Value of the subject
Specially Designated Defaulted Mortgage Loan.

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

            (c) The Majority Controlling Class Certificateholder (exclusive of
the Depositor, the related Mortgage Loan Seller, or any of their respective
Affiliates and/or agents) may, at its option, purchase from the Trust any
Specially Designated Defaulted Mortgage Loan (such option, the "Purchase
Option"), at a cash price (the "Option Price") equal to the Fair Value of such
Mortgage Loan (as most recently determined by the applicable Special Servicer
and reported to the Trustee and the applicable Master Servicer as provided in
Section 3.18(b) above) or, if no such Fair Value has yet been established as
provided in Section 3.18(b) above or if the applicable Special Servicer is in
the process of redetermining such Fair Value because of a change in
circumstances, equal to the Purchase Price; provided, that with respect to an A
Loan, the option holder's rights under this Section 3.18(c) are subject to the
rights of the related B Loan Holder to purchase the A Loan pursuant to the terms
of the related A/B Intercreditor Agreement; provided, further, that:

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

          (ii) the Purchase Option with respect to any Specially Designated
     Defaulted Mortgage Loan will be assignable by the Majority Controlling
     Class Certificateholder during the Option Period to a third party other
     than the Depositor, the related Mortgage Loan Seller, 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 Mortgage Loan is not exercised by the Majority Controlling Class
     Certificateholder or any assignee thereof within 30 days after the Fair
     Value of such Mortgage Loan has initially been established as provided in
     Section 3.18(b) above, then the Majority Controlling Class
     Certificateholder shall be deemed to have assigned such Purchase Option,
     for a 30-day period only, to the applicable Special Servicer;

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

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

provided, that, if the Depositor, a Mortgage Loan Seller or any Affiliate or
agent of the Depositor or a Mortgage Loan Seller shall, as a Special Servicer or
the Majority Controlling Class Certificateholder, hold the Purchase Option with
respect to any Specially Designated Defaulted Mortgage Loan, then it may, at any
time after the commencement of the applicable Option Period, waive such Purchase
Option by delivering written notice of such waiver to the applicable Master
Servicer, the applicable Special Servicer (if the holder of such Purchase Option
is not acting in such capacity) and the Trustee.

            Notwithstanding anything contained in clause (vi) of the preceding
paragraph to the contrary, if the General Master Servicer or the Trustee is
required to confirm or reject a 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 that such Special Servicer's Fair Value
determination as contemplated by such clause (vi). In the event that the General
Master Servicer or the Trustee designates such a third party to make such
determination, neither the General Master Servicer nor the Trustee will assume
any responsibility for such third party's determination, and the General Master
Servicer and the Trustee shall be entitled to conclusively rely upon such third
party's determination. The General Master Servicer may pay, or the Trustee may
direct the General Master Servicer to pay, as the case may be, to such a third
party (or, if the General Master Servicer or the Trustee makes the confirmation
of a Special Servicer's Fair Value determination as contemplated by clause (vi)
of the preceding paragraph, the General Master Servicer may pay itself or the
Trustee, as the case may be) a fee of up to $2,500 plus (subject to the next
sentence) related costs and expenses out of the Collection Account maintained by
the General Master Servicer. The reasonable costs of all appraisals, inspection
reports and broker opinions of value, incurred by the General Master Servicer,
the Trustee or any such third party pursuant to this paragraph or clause (vi) of
the preceding paragraph shall be advanced by the General Master Servicer 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 Mortgage Loan by providing to the
Trustee, the applicable Master Servicer and the applicable Special Servicer--

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

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

The actual purchase of such Specially Designated Defaulted Mortgage Loan shall
occur (by delivery of cash in the amount of the applicable Option Price to the
applicable Special Servicer for deposit in the applicable Master Servicer's
Collection Account) no later than 20 days after the later of (i) such exercise
of the Purchase Option with respect to such Mortgage Loan and (ii) if
applicable, the confirmation of such Special Servicer's Fair Value of such
Mortgage Loan in accordance with clause (vi) of the first paragraph of this
Section 3.18(c) and/or in accordance with the second paragraph of this Section
3.18(c).

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

            (d) The applicable Special Servicer shall use its reasonable
efforts, consistent with the Servicing Standard, to solicit cash bids for each
REO Property in such manner as will be reasonably likely to realize a fair price
(determined pursuant to Section 3.18(e) below) for any REO Property within a
customary and normal time frame for the sale of comparable properties (and, in
any event, within the time period provided for by Section 3.16(a)). Such Special
Servicer shall accept the first (and, if multiple cash bids are received by a
specified bid date, the highest) cash bid received from any Person that
constitutes a fair price (determined pursuant to Section 3.18(e) below) for such
REO Property. If such Special Servicer reasonably believes that it will be
unable to realize a fair price (determined pursuant to Section 3.18(e) below)
with respect to any REO Property within the time constraints imposed by Section
3.16(a), then such Special Servicer shall, consistent with the Servicing
Standard 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 applicable Special Servicer shall give the Trustee, the
applicable Master Servicer and the Controlling Class Representative not less
than five (5) Business Days' prior written notice of its intention to sell any
REO Property pursuant to this Section 3.18(d). No Interested Person shall be
obligated to submit a bid to purchase any REO Property, and notwithstanding
anything to the contrary herein, neither the Trustee, in its individual
capacity, nor any of its Affiliates may bid for or purchase any REO Property
pursuant hereto.

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

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

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

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

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

            Section 3.19 Additional Obligations of Master Servicers

            (a) Each Master Servicer as to which such Master Servicer is the
applicable 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 in respect of Performing Mortgage Loans during
the most recently ended Collection Period and as to which such Master Servicer
is the applicable Master Servicer (other than as a result of the receipt of
Insurance Proceeds and/or Condemnation Proceeds), and (ii) the aggregate of (A)
with respect to such of those Prepayment Interest Shortfalls incurred, that
portion of such Master Servicer's Master Servicing Fees for the related
Collection Period that is, in the case of each and every Mortgage Loan and REO
Mortgage Loan as to which such Master Servicer is the applicable Master Servicer
for which such Master Servicing Fees are being paid in such Collection Period,
calculated at 0.005% (one-half of one basis point) per annum for the General
Master Servicer and 0.02% per annum for the Co-op Master Servicer, and (B) all
Prepayment Interest Excesses received by such Master Servicer during the most
recently ended Collection Period; provided, however, that if a Prepayment
Interest Shortfall occurs as a result of the applicable Master Servicer's
allowing the related Borrower to deviate from the terms of the related Mortgage
Loan Documents regarding Principal Prepayments (other than (X) subsequent to a
material default under the related Mortgage Loan Documents, (Y) pursuant to
applicable law or a court order, or (Z) at the request or with the consent of
the Controlling Class Representative), then, the amount specified in clause
(ii)(A) above shall be an amount equal to the entire Master Servicing Fee with
respect to such Collection Period.

            (b) No more frequently than once per calendar month, each Special
Servicer may require the applicable Master Servicer, and such Master Servicer
shall be obligated, out of such Master Servicer's own funds, to reimburse such
Special Servicer for any Servicing Advances (other than Nonrecoverable Servicing
Advances) made by but not previously reimbursed to such Special Servicer,
together with interest thereon at the Reimbursement Rate from the date made to,
but not including, the date of reimbursement, upon such Special Servicer
providing an Officer's Certificate to the applicable Master Servicer setting
forth the details of the Servicing Advance upon which such Master Servicer shall
conclusively rely in reimbursing the Special Servicer. 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 such Special Servicer. Upon a Master Servicer's
reimbursement to a Special Servicer of any Servicing Advance and payment to such
Special Servicer of interest thereon, all in accordance with this Section
3.19(b), such Master Servicer shall for all purposes of this Agreement be deemed
to have made such Servicing Advance at the same time as such Special Servicer
actually made such Servicing Advance, and accordingly, such Master Servicer
shall be entitled to reimbursement for such Servicing Advance, together with
interest thereon in accordance with Sections 3.05(a) and 3.11(g), at the same
time, in the same manner and to the same extent as such Master Servicer would
otherwise have been entitled if it had actually made such Servicing Advance at
the time such Special Servicer did.

            Notwithstanding anything to the contrary contained in any other
Section of this Agreement, if a Special Servicer is required under this
Agreement (but subject to the following paragraph), to make any Servicing
Advance but does not desire to do so, such Special Servicer may, in its sole
discretion, request that the applicable 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, 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 such Master
Servicer may reasonably request; provided, however, that such Special Servicer
shall not be entitled to make such a request (other than for emergency advances)
more frequently than once per calendar month (although such request may relate
to more than one Servicing Advance). The applicable Master Servicer shall have
the obligation to make any such Servicing Advance (other than a Nonrecoverable
Servicing Advance) that it is so requested by such Special Servicer to make, by
payment of such amount to such Special Servicer within five Business Days of
such Master Servicer's receipt of such request. Such Special Servicer shall then
be responsible for disbursing such amounts to the appropriate payees. Subject to
the preceding sentence, if the request is timely and properly made, such Special
Servicer shall be relieved of any obligations with respect to a Servicing
Advance that it so requests the applicable Master Servicer to make (regardless
of whether or not the applicable Master Servicer shall make such Servicing
Advance). Each Master Servicer shall be entitled to reimbursement for any
Servicing Advance made by it at the direction of a Special Servicer, together
with interest thereon in accordance with Sections 3.05(a) and 3.11(g), at the
same time, in the same manner and to the same extent as such Master Servicer is
entitled with respect to any other Servicing Advances made thereby.

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

            (c) Promptly following the occurrence of an Appraisal Trigger Event
with respect to any Mortgage Loan, the applicable Special Servicer shall obtain
(or, if such Mortgage Loan has a Stated Principal Balance of $2,000,000 or less,
unless the Controlling Class Representative permits 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 applicable 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 applicable Master Servicer and the Controlling Class
Representative. If such Appraisal is obtained from a Qualified Appraiser, the
cost thereof shall be paid by and reimbursable to the applicable Master Servicer
as a Servicing Advance. Promptly following the receipt of, and based upon, such
Appraisal, such Special Servicer shall determine and report to the Trustee and
the applicable 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 Mortgage Loan or REO Mortgage Loan remains a
Required Appraisal Loan, the applicable Special Servicer shall, within 30 days
of each anniversary of such loan'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, at its discretion, unless the Controlling Class
Representative objects, conduct) an update of the prior Appraisal. If such
update is obtained from a Qualified Appraiser, the cost thereof shall be paid by
and reimbursable to the applicable Master Servicer as a Servicing Advance.
Promptly following the receipt of, and based upon, such update, such Special
Servicer shall redetermine, in consultation with the Controlling Class
Representative, and report to the Trustee and the applicable 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 applicable Special Servicer obtain a new Appraisal of the subject
Mortgaged Property in accordance with MAI standards, at the expense of the
Controlling Class Certificateholders, and upon receipt of such Appraisal the
applicable Special Servicer shall redetermine the Appraisal Reduction Amount.

            (d) The General Master Servicer shall pay, without any right of
reimbursement therefor, the post-Closing Date fees of Moody's for ongoing
surveillance of the Rated Certificates; provided that the General Master
Servicer shall not be required to pay without reimbursement the fees charged by
any Rating Agency for a confirmation as to the lack of an Adverse Rating Event
with respect to any Class of Rated Certificates in connection with any other
particular matter, unless the General Master Servicer has failed to use efforts
consistent with the Servicing Standard to collect such fees from the Borrower,
which shall include, if it has the right to do so under the applicable Mortgage
Loan, conditioning its consent or approval on such payment by the Borrower
unless such condition would be a violation of applicable law or the Servicing
Standard.

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

            (f) With respect to each Mortgage Loan that provides for defeasance,
the applicable Master Servicer shall, to the extent permitted by the terms of
such Mortgage Loan, require the related Borrower (i) to provide replacement
collateral consisting of government securities within the meaning of Treasury
Regulations Section 1.860G-2(a)(8)(i) in an amount sufficient to make all
scheduled payments under the Mortgage Loan (or defeased portion thereof) when
due (and assuming, in the case of an ARD Mortgage Loan, to the extent consistent
with the related loan documents, that such Mortgage Loan matures on its
Anticipated Repayment Date), (ii) to deliver a certificate from an independent
certified public accounting firm certifying that the replacement collateral is
sufficient to make such payments, (iii) at the option of the applicable Master
Servicer, to designate a single purpose entity (which may be a subsidiary of
such Master Servicer established for the purpose of assuming all defeased
Mortgage Loans) to assume the Mortgage Loan (or defeased portion thereof) and
own the defeasance collateral and, if the subject Mortgage Loan has a Cut-off
Date Principal Balance equal to or greater than $5,000,000, and, if the related
Mortgage Loan Documents permit the lender to require or expressly requires the
borrower to provide an opinion of Counsel to the effect that such entity will
not be consolidated with its principals; provided, that if the subject Mortgage
Loan has a Cut-off Date Principal Balance less than $5,000,000 and the related
Mortgage Loan Documents do not require the related Borrower to pay for, or do
not permit the lender to require such Opinion of Counsel, such requirement shall
be waived, (iv) to implement such defeasance only after the second anniversary
of the Closing Date, (v) to provide an Opinion of Counsel that the Trustee has a
perfected, first priority security interest in the new collateral, and (vi) in
the case of a partial defeasance of the Mortgage Loan, to defease a principal
amount equal to at least 125% of the allocated loan amount for the Mortgaged
Property or Properties to be released. If the subject Mortgage Loan has a
Cut-off Date Principal Balance less than $20,000,000 and an outstanding
principal balance less than 2% of the then aggregate Stated Principal Balance of
the Mortgage Pool, and if either the terms of the Mortgage Loan permit the
applicable Master Servicer to impose the foregoing requirements or such Master
Servicer satisfies such requirements on its own, then confirmation that such
defeasance will not result in an Adverse Rating Event is not required so long as
the applicable Master Servicer delivers to S&P a certification in the form
attached hereto as Exhibit N. In such case, the applicable Master Servicer shall
provide the Rating Agencies and the Controlling Class Representative with notice
that the foregoing requirements have been met. However, if the subject Mortgage
Loan has a Cut-off Date Principal Balance greater than or equal to $20,000,000
or an outstanding principal balance greater than or equal to 2% of the aggregate
Stated Principal Balance of the Mortgage Pool, or if the terms of the Mortgage
Loan do not permit such Master Servicer to impose such requirements and such
Master Servicer does not satisfy such requirements on its own, then such Master
Servicer shall so notify the Rating Agencies and the Controlling Class
Representative and, so long as such a requirement would not violate applicable
law or the Servicing Standard, obtain a confirmation that such defeasance will
not result in an Adverse Rating Event. Subject to the related Mortgage Loan
Documents and applicable law, the applicable Master Servicer shall not execute a
defeasance unless (i) the Mortgage Loan requires the Borrower to pay all Rating
Agency fees associated with defeasance (if Rating Agency confirmation of
no-downgrade is a specific condition precedent thereto) and all expenses
associated with defeasance or other arrangements for payment of such costs are
made at no expense to the Trust Fund or the applicable Master Servicer
(provided, however, that in no event shall such proposed "other arrangements"
result in any liability to the Trust Fund including any indemnification of the
applicable Master Servicer or the applicable Special Servicer which may result
in legal expenses to the Trust Fund), and (ii) the Borrower is required to
provide all Opinions of Counsel, including Opinions of Counsel that the
defeasance will not cause an Adverse REMIC Event or an Adverse Grantor Trust
Event and that the Mortgage Loan Documents are fully enforceable in accordance
with their terms (subject to bankruptcy, insolvency and similar standard
exceptions), and any applicable rating confirmations.

            (g) The applicable Master Servicer shall, as to each Mortgage Loan
which is secured by the interest of the related Borrower under a Ground Lease,
promptly (and in any event within 45 days) after the Closing Date notify the
related ground lessor of the transfer of such Mortgage Loan to the Trust
pursuant to this Agreement and inform such ground lessor that any notices of
default under the related Ground Lease should thereafter be forwarded to such
Master Servicer.

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

            Section 3.20 Modifications, Waivers, Amendments and Consents

            (a) Each Special Servicer (solely as to a Specially Serviced
Mortgage Loan for which it acts as Special Servicer) or each Master Servicer
(solely as to a Performing Mortgage Loan for which it acts as Master Servicer)
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 (and, in the case of any A Loan or B Loan, subject to the
terms of the related A/B Intercreditor Agreement) and, further to each of the
following limitations, conditions and restrictions:

          (i) other than as provided in Sections 2.03(b), 3.02, 3.08, 3.20(f)
     and 3.20(g), the applicable 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 affect the
     security for such Mortgage Loan, unless such Master Servicer has obtained
     the consent of the applicable Special Servicer (it being understood and
     agreed that (A) such Master Servicer shall promptly provide the applicable
     Special Servicer with notice of any Borrower request for such modification,
     waiver or amendment, such Master Servicer's recommendations and analysis,
     and with all information reasonably available to such Master Servicer that
     the applicable Special Servicer may reasonably request in order to withhold
     or grant any such consent, (B) the applicable Special Servicer shall decide
     whether to withhold or grant such consent in accordance with the Servicing
     Standard and (C) if any such consent has not been expressly denied within
     ten Business Days of the applicable Special Servicer's receipt from such
     Master Servicer of such Master Servicer's recommendations and analysis and
     all information reasonably requested thereby and reasonably available to
     such Master Servicer in order to make an informed decision (or, if the
     applicable Special Servicer did not request any information, within 15
     Business Days from such notice), such consent shall be deemed to have been
     granted);

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

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

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

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

          (vi) the applicable Special Servicer shall not permit (or, in the case
     of a Performing Mortgage Loan, consent to the applicable Master Servicer's
     permitting) any Borrower to add or substitute any real estate collateral
     for its Mortgage Loan unless the applicable Special Servicer shall have
     first (A) determined in its reasonable judgment, based upon a Phase I
     Environmental Assessment (and any additional environmental testing that
     such Special Servicer deems necessary and prudent) conducted by an
     Independent Person who regularly conducts Phase I Environmental
     Assessments, at the expense of the related Borrower, that such additional
     or substitute collateral is in compliance with applicable environmental
     laws and regulations and that there are no circumstances or conditions
     present with respect to such new collateral relating to the use, management
     or disposal of any Hazardous Materials for which investigation, testing,
     monitoring, containment, clean-up or remediation would be required under
     any then applicable environmental laws or regulations and (B) received, at
     the expense of the related Borrower, written confirmation from each Rating
     Agency that such addition or substitution of collateral will not, in and of
     itself, result in an Adverse Rating Event with respect to any Class of
     Rated Certificates; and

          (vii) the applicable Special Servicer shall not release (or, in the
     case of a Performing Mortgage Loan, consent to the applicable 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
     where a Mortgage Loan (or, in the case of a Cross-Collateralized Group,
     where such entire Cross-Collateralized Group) is satisfied, or except in
     the case of a release where (A) either (1) the use of the collateral to be
     released will not, in the reasonable judgment of such 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 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), (B) with respect to
     Performing Loans, the remaining Mortgaged Property (together with any
     substitute collateral) is, in such Special Servicer's reasonable judgment,
     adequate security for the remaining Mortgage Loan and (C) with respect to
     Performing Loans, such release would not, in and of itself, result in an
     Adverse Rating Event with respect to any Class of Rated Certificates (as
     confirmed in writing to the Trustee by each Rating Agency);

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

            (b) Neither of the Special Servicers and neither of the Master
Servicers shall have any liability to the Trust, the Certificateholders or any
other Person if its analysis and determination that the modification, waiver,
amendment or other action contemplated by Section 3.20(a) is reasonably likely
to produce a greater recovery to Certificateholders on a present value basis
than would liquidation should prove to be wrong or incorrect, so long as the
analysis and determination were made on a reasonable basis by such Special
Servicer or such Master Servicer and consistent with the Servicing Standard.

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

            (d) Each Master Servicer and each Special Servicer may, as a
condition to its granting any request by a Borrower for consent, modification,
waiver or indulgence or any other matter or thing, the granting of which is
within such Master Servicer's or such Special Servicer's, as the case may 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) 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 a Master Servicer and/or a
Special Servicer with respect to any Mortgage Loan shall be allocable between
such parties, as Additional Master Servicing Compensation and Additional Special
Servicing Compensation, respectively, as provided in Section 3.11.

            (e) All modifications, amendments, material waivers and other
material actions entered into or taken in respect of the Mortgage Loans pursuant
to this Section 3.20 (other than waivers of Default Charges) shall be in
writing. Each Special Servicer and each Master Servicer shall notify the other
such applicable party, each Rating Agency, the Trustee and the Controlling Class
Representative, 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 (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 such modification, waiver, amendment or
other action, promptly (and in any event within ten Business Days) following the
execution thereof. In addition, following the execution of any modification,
waiver or amendment agreed to by a Special Servicer, or by a Master Servicer
with any required consent of the applicable Special Servicer, pursuant to
Section 3.20(a) above, the applicable Special Servicer or the applicable Master
Servicer, as applicable, shall deliver to the other such party, the Trustee and
the Rating Agencies an Officer's Certificate certifying that all of the
requirements of Section 3.20(a) have been met and, in the case of the applicable
Special Servicer, setting forth in reasonable detail the basis of the
determination made by it pursuant to Section 3.20(a)(ii); provided that, if such
modification, waiver or amendment involves an extension of the maturity of any
Mortgage Loan, such Officer's Certificate shall be so delivered before the
modification, waiver or amendment is agreed to. The applicable Master Servicer
shall notify the B Loan Holder of any modification of the monthly payments of
the related Loan, and such monthly payments shall be allocated in accordance
with the related A/B Intercreditor Agreements.

            (f) With respect to any ARD Mortgage Loan after its Anticipated
Repayment Date, the applicable Master Servicer shall be permitted, with the
consent of the Controlling Class Representative, to waive (such waiver to be in
writing addressed to the related Borrower, with a copy to the Trustee) all or
any portion of the accrued Post-ARD Additional Interest in respect of such ARD
Mortgage Loan if (i) such ARD Mortgage Loan is a Performing Mortgage Loan, (ii)
the related Borrower has requested the right to prepay such ARD Mortgage Loan in
full together with all payments required by the related Mortgage Loan Documents
in connection with such prepayment except for such accrued Post-ARD Additional
Interest, and (iii) the applicable Master Servicer has determined, in its
reasonable judgment, that waiving such Post-ARD Additional Interest is in
accordance with the Servicing Standard. The applicable Master Servicer shall
prepare all documents necessary and appropriate to effect any such waiver and
shall coordinate with the related Borrower for the execution and delivery of
such documents.

            (g) Notwithstanding anything in this Section 3.20 or in Section 3.08
or Section 3.24 to the contrary, a Master Servicer shall not be required to seek
the consent of or provide prior notice to, the applicable Special Servicer or
any Certificateholder or obtain any confirmation of the Certificate ratings from
the Rating Agencies in order to approve the following modifications, waivers or
amendments of the Mortgage Loans for which it acts as Master Servicer: (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, and permitting subordinate debt with respect to Co-op Mortgage
Loans as to which the NCBFSB Subordinate Debt Conditions have been satisfied, in
accordance with Section 3.08; (iii) releases of parcels of a Mortgaged Property
(provided that any such releases 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 are related to any pending or
threatened condemnation action); (iv) grants of easements or rights of way that
do not materially affect the use or value of a Mortgaged Property or the
Borrower's ability to make any payments with respect to the related Mortgage
Loan; (v) routine leasing activities that affect less than the greater of 20% of
the net rentable area of the Mortgaged Property or 10,000 square feet of the
Mortgaged Property and (vi) approval of annual budgets to operate the Mortgaged
Property; 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 either Trust REMIC or an Adverse Grantor Trust Event with respect to
the Grantor Trust, (y) would be consistent with the Servicing Standard, and (z)
shall not violate the terms, provisions or limitations of this Agreement or any
other document contemplated hereby.

            (h) The applicable Master Servicer shall not terminate or replace,
or consent to the termination or replacement of, any property manager with
respect to any Mortgaged Property, and the applicable Master Servicer shall not
terminate or change or consent to the termination or change of the franchise for
any Mortgage Property operated as a hospitality property, in any event without
the prior written consent of the applicable Special Servicer (it being
understood and agreed that (A) such Master Servicer shall promptly provide such
Special Servicer with its analysis, recommendations and all information that
such Special Servicer may reasonably request and which information is in the
possession of such Master Servicer, in order to withhold or grant any such
consent, (B) such Special Servicer shall decide whether to withhold or grant
such consent in accordance with the Servicing Standard, (C) if any such consent
has not been expressly denied within ten Business Days of such Special
Servicer's receipt from such Master Servicer of such analysis, recommendation
and all information reasonably requested thereby in order to make an informed
decision (or, if such Special Servicer did not request any information, within
ten Business Days from such notice), such consent shall be deemed to have been
granted and (D) such consent shall not be required with respect to Co-op
Mortgage Loans that are Performing Mortgage Loans if the Co-op Master Servicer
provides an Officer's Certificate to the Controlling Class Representative
stating that such termination or replacement is not the result of a material
adverse condition at the related Mortgaged Property.

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

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

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

            (a) Upon determining that a Servicing Transfer Event has occurred
with respect to any Mortgage Loan, the applicable Master Servicer shall
immediately give notice thereof to the Controlling Class Representative, and if
the applicable Master Servicer is not also the applicable Special Servicer, such
Master Servicer shall immediately give notice thereof, and shall deliver the
related Servicing File, to the applicable Special Servicer and shall use its
best efforts to provide such Special Servicer with all information, documents
(or copies thereof) and records (including records stored electronically on
computer tapes, magnetic discs and the like) relating to the Mortgage Loan and
reasonably requested by the applicable Special Servicer to enable it to assume
its functions hereunder with respect thereto without acting through a
Sub-Servicer. To the extent such is in the possession of the applicable Master
Servicer or any Sub-Servicer thereof, the information, documents and records to
be delivered by such Master Servicer to the applicable Special Servicer pursuant
to the prior sentence shall include, but not be limited to, financial
statements, appraisals, environmental/engineering reports, leases, rent rolls
(except with respect to Co-op Mortgage Loans), title insurance policies, UCC's
and tenant estoppels. The applicable Master Servicer shall use its best efforts
to comply with the preceding two sentences within five Business Days of the
occurrence of each related Servicing Transfer Event. No later than 10 Business
Days before such Master Servicer is required to deliver a copy of the related
Servicing File to the applicable Special Servicer, it shall review such
Servicing File and request from the Trustee any material documents that it is
aware are missing from such Servicing File. Any B Loan shall constitute a
Specially Serviced Mortgage Loan for which the applicable Special Servicer is
responsible for so long as the related A Loan is a Specially Serviced Mortgage
Loan.

            Upon determining that a Specially Serviced Mortgage Loan has become
a Corrected Mortgage Loan and if the applicable Master Servicer is not also the
applicable Special Servicer, such Special Servicer shall immediately give notice
thereof, and shall return the related Servicing File within five Business Days,
to the applicable Master Servicer; and, upon giving such notice and returning
such Servicing File to the applicable Master Servicer, such Special Servicer's
obligation to service such Mortgage Loan, and such Special Servicer's right to
receive the Special Servicing Fee with respect to such Mortgage Loan, shall
terminate, and the obligations of the applicable Master Servicer to service and
administer such Mortgage Loan shall resume.

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

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

            (c) Each Master Servicer and each Special Servicer shall 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 the Mortgage Loans for which it
acts as Master Servicer or Special Servicer and any related REO Properties 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,
each of Master Servicer and each Special Servicer shall be entitled to rely upon
written information provided to it by the other.

            Section 3.22 Sub-Servicing Agreements

            (a) Each Master Servicer and, subject to Section 3.22(f), each
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, 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 Sub-Servicer to comply in all material
respects with all of the applicable conditions of this Agreement; (ii) provides
that if such Master Servicer or such Special Servicer, as the case may be, shall
for any reason no longer act in such capacity hereunder (including by reason of
an Event of Default), the Trustee or its designee or any other successor to such
Master Servicer or such Special Servicer, as the case may be, may thereupon
assume all of the rights and, except to the extent they arose prior to the date
of assumption, obligations of such Master Servicer or such Special Servicer, as
the case may be, under such agreement or, alternatively, may terminate such
Sub-Servicing Agreement without cause and without payment of any penalty or
termination fee (provided, however, that a Designated Sub-Servicer Agreement may
not be terminated except for cause, which will include the occurrence of any
Adverse Rating Event resulting from the subject Sub-Servicer's acting in such
capacity); (iii) provides that the Trustee, for the benefit of the
Certificateholders, shall be a third-party beneficiary under such agreement, but
that (except to the extent the Trustee or its designee assumes the obligations
of such Master Servicer or such 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 Mortgage Loan
pursuant to this Agreement to terminate such agreement with respect to such
purchased Mortgage Loan at its option and without penalty; (v) does not permit
the subject Sub-Servicer to foreclose on a Mortgaged Property or to enter into
or consent to any modification, waiver or amendment or otherwise take any action
on behalf of such Master Servicer or Special Servicer, as the case may be,
contemplated by Section 3.20 hereof without the consent of such Master Servicer
or Special Servicer, as the case may be; and (vi) does not permit the
Sub-Servicer any rights of indemnification out of the Trust Fund except through
such Master Servicer or the Special Servicer, as the case may be, have pursuant
to Section 6.03; provided that the appointment by such Master Servicer or
Special Servicer of a third-party contractor for the purpose of performing
discrete, ministerial functions shall not be subject to this Section 3.22
(except that such Master Servicer or Special Servicer, as the case may be, shall
remain responsible for the actions of such third-party contractors and shall pay
all fees and expenses of such third-party contractors, unless otherwise
expressly provided herein). No Sub-Servicing Agreement entered into by a Master
Servicer shall purport to delegate or effectively delegate to the related
Sub-Servicer any of the rights or obligations of a Special Servicer with respect
to any Specially Serviced Mortgage Loan or otherwise. Each Sub-Servicing
Agreement entered into by a Special Servicer shall relate only to Specially
Serviced Mortgage Loans for which such Special Servicer acts as Special Servicer
and any related REO Properties and shall not purport to delegate or effectively
delegate to the related Sub-Servicer any of the rights or obligations of a
Master Servicer with respect to any Mortgage Loan, including any Specially
Serviced Mortgage Loan. Each Master Servicer and each Special Servicer shall
each notify such other parties, the Trustee and the Depositor in writing
promptly of the appointment by it of any Sub-Servicer (other than a Designated
Sub-Servicer). Each Master Servicer and each Special Servicer shall deliver to
the Trustee copies of all Sub-Servicing Agreements, and any amendments thereto
and modifications thereof, entered into by it promptly upon its execution and
delivery of such documents. References in this Agreement to actions taken or to
be taken by a Master Servicer or a Special Servicer include actions taken or to
be taken by a Sub-Servicer on behalf of a Master Servicer or a Special Servicer,
as the case may be; and, in connection therewith, all amounts advanced by any
Sub-Servicer to satisfy the obligations of a Master Servicer or a Special
Servicer hereunder to make Advances shall be deemed to have been advanced by
such Master Servicer or such Special Servicer, as the case may be, out of its
own funds and, accordingly, such Advances shall be recoverable by such
Sub-Servicer in the same manner and out of the same funds as if such
Sub-Servicer were such Master Servicer or such Special Servicer, as the case may
be. Such Advances shall accrue interest in accordance with Sections 3.11(g)
and/or 4.03(d), such interest to be allocable between the applicable Master
Servicer or the applicable Special Servicer, as the case may be, and such
Sub-Servicer as they may agree. For purposes of this Agreement, each Master
Servicer and each Special Servicer shall 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 to ensure the
enforceability of the subject Mortgage Loans and to avoid any loss or liability
to the Trust.

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

            (d) If a Master Servicer or a Special Servicer ceases to serve as
such under this Agreement for any reason (including by reason of an Event of
Default), then the Trustee or other successor Master Servicer or Special
Servicer, as the case may be, shall succeed to the rights and assume the
obligations of such Master Servicer or such Special Servicer under any
Sub-Servicing Agreement 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 such Master Servicer or such Special Servicer, as
applicable, at its expense shall, upon request of the Trustee, deliver to the
assuming party all documents and records relating to such Sub-Servicing
Agreement and the Mortgage Loans then being serviced thereunder and an
accounting of amounts collected and held on behalf of it thereunder, and
otherwise use reasonable efforts to effect the orderly and efficient transfer of
the Sub-Servicing Agreement to the assuming party.

            (e) Notwithstanding any Sub-Servicing Agreement, each Master
Servicer and each Special Servicer shall remain obligated and liable to the
Trustee and the Certificateholders for the performance of their respective
obligations and duties under this Agreement in accordance with the provisions
hereof to the same extent and under the same terms and conditions as if each
alone were servicing and administering the Mortgage Loans or REO Properties for
which it is responsible. No appointment of a Sub-Servicer shall result in any
additional expense to the Trustee, the Certificateholders or the Trust other
than those contemplated herein.

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

            Section 3.23 Controlling Class Representative

            (a) The Holders (or, in the case of Book-Entry Certificates, the
Certificate Owners) of Certificates representing more than 50% of the Class
Principal Balance of the Controlling Class shall be entitled in accordance with
this Section 3.23 to select a representative (each, a "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 Depository or the Depository Participants, the Certificate
Owners) of the Controlling Class that they may select a Controlling Class
Representative. Such notice shall set forth the process established by the
Trustee for selecting a Controlling Class Representative, which process may
include the designation of the Controlling Class Representative by the related
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 the Trustee has received confirmation that the
appointment of such Controlling Class Representative is acceptable to the
Majority Controlling Class Certificateholder and 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). Anthracite shall be the initial Controlling Class Representative
without any further notification or confirmation referred to in this paragraph.

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

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

            (d) 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, in proportion to their respective
Percentage Interests in such Class, and not by the Trust. Notwithstanding the
foregoing, if a claim is made against the Controlling Class Representative by a
Borrower with respect to this Agreement or any particular Mortgage Loan, the
Controlling Class Representative shall immediately notify the Trustee, the
Master Servicers and the Special Servicers, whereupon (if the Special Servicers,
the Master Servicers, the Trustee or the Trust are also named parties to the
same action and, in the sole judgment of the applicable Master Servicer or the
applicable Special Servicer, (i) such Controlling Class Representative had acted
in good faith, without negligence or willful misfeasance, with regard to the
particular matter, and (ii) there is no potential for the Special Servicers, the
Master Servicers, the Trustee or the Trust to be an adverse party in such action
as regards such Controlling Class Representative) the applicable Master Servicer
or the applicable Special Servicer or, if such action does not relate to a
specific Mortgage Loan, the General 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 any 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 Servicers with respect to the Special Servicers' taking, or
consenting to the Master Servicers' taking, any of the actions identified in
clauses (i) through (ix) of the following sentence. In addition, notwithstanding
anything in any other Section of this Agreement to the contrary, but in all
cases subject to Section 3.20(g) and Section 3.24(b), a Special Servicer will
not be permitted to take, or consent to the applicable Master Servicer's taking,
any of the actions identified in clauses (i) through (ix) of this sentence,
unless and until such Special Servicer has notified the Controlling Class
Representative in writing of such Special Servicer's intent to take or permit
the particular action and the Controlling Class Representative has consented (or
has failed to object) thereto in writing within five Business Days of having
been notified thereof in writing and having been provided with all reasonably
requested information with respect thereto:

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

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

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

          (iv) any proposed sale of an REO Property for less than the Stated
     Principal Balance of, and accrued interest (other than Default Interest and
     Post-ARD Additional Interest) on, the related Mortgage Loan, except in
     connection with a termination of the Trust Fund pursuant to Section 9.01;

          (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 collateral for any Mortgage Loan (other than in
     accordance with the specific terms of, or upon satisfaction of, such
     Mortgage Loan);

          (vii) any acceptance of substitute or additional collateral for any
     Specially Serviced Mortgage Loan (other than in accordance with the
     specific terms of such Mortgage Loan);

          (viii) any release of Earn-Out Reserve Funds or related Letter of
     Credit with respect to a Mortgaged Property securing a Mortgage Loan; and

          (ix) any waiver of a due-on-sale or due-on-encumbrance clause in any
     Mortgage Loan (other than in the case of a waiver of a "due-on-encumbrance"
     clause, a Co-op Mortgage Loan as to which the NCBFSB Subordinate Debt
     Conditions are satisfied (in which event the applicable Master Servicer
     shall, at least ten (10) days prior to taking such action, provide the
     Controlling Class Representative with an Officer's Certificate stating such
     Master Servicer's intent to take such action, which Officer's Certificate
     shall describe the circumstances of such action, including all information
     necessary for the Controlling Class Representative to determine whether the
     NCBFSB Subordinate Debt Conditions have been satisfied including all
     required calculations)).

provided that, if the applicable Special Servicer or the applicable Master
Servicer, as applicable, determines that immediate action is necessary to
protect the interests of the Certificateholders (as a whole), the applicable
Special Servicer may take any such action without waiting for the response of
the Controlling Class Representative.

            In addition, subject to Section 3.24(b), the Controlling Class
Representative may direct a Special Servicer to take, or to refrain from taking,
such actions as such Controlling Class Representative may deem advisable or as
to which provision is otherwise made herein. Upon reasonable request, a Special
Servicer shall provide the Controlling Class Representative with any information
in such Special Servicer's possession with respect to such matters, including,
without limitation, its reasons for determining to take a proposed action.

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

            (b) Notwithstanding anything herein to the contrary, (i) a 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, during the period prior to the initial selection of a Controlling
Class Representative and, if any Controlling Class Representative resigns or is
removed, during the period following 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 each Master Servicer and Special Servicer shall ignore and act without
regard to any such advice, direction or objection that such Master Servicer or
Special Servicer has determined, in its reasonable judgment, would) (A) require
or cause a Master Servicer or such Special Servicer to violate applicable law,
the terms of any Mortgage Loan or any other Section of this Agreement, including
such Master Servicer's or Special Servicer's obligation to act in accordance
with the Servicing Standard, (B) result in an Adverse REMIC Event with respect
to either Trust REMIC or an Adverse Grantor Trust Event with respect to the
Grantor Trust, (C) expose the Trust, the Depositor, a Master Servicer, a Special
Servicer, any Fiscal Agent, the Trustee, 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 a Master Servicer's or
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 Controlling Class Representative does not have any duties to
the Holders of any Class of Certificates other than the Controlling Class (and
with respect to such Controlling Class Holders shall have no liability for any
action taken or omitted which does not constitute negligence, bad faith or
willful misfeasance); (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 or for any action taken or omitted, 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 Servicers

            (a) Subject to Section 3.25(b), the Controlling Class Representative
may, upon not less than ten days' prior written notice to the respective parties
hereto, remove 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

respect to any Mortgage Loan or REO Property.

            Section 3.26 Application of Default Charges

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

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

          Second, to reimburse the Trust for any Advance Interest paid to any
     Fiscal Agent, the Trustee, the Master Servicers or the Special Servicers
     since the Closing Date with respect to such Mortgage Loan or REO Mortgage

     Default Charges on such Mortgage Loan or REO Mortgage Loan, as the case may
     be;

          Third,to pay any other outstanding expense incurred with respect to
     such Mortgage Loan or REO Mortgage Loan, as the case may be, that, if not
     paid from Default Charges collected on such Mortgage Loan or REO Mortgage
     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 Mortgage Loan
     or REO Mortgage Loan, as the case may be, and previously paid from a source

     the case may be; and

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

            (b) Default Charges applied to reimburse the Trust pursuant to
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)

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 Mortgage Loan or REO Mortgage 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).

Lower-Tier Interest less the amount actually distributed in respect of such
Uncertificated Lower-Tier Interest shall equal the sum of (i) the Interest
Shortfall Amount allocated to such Uncertificated Lower-Tier Interest's Related
Certificate and allocated pro rata to the Class LA-1-1, Class LA-1-2, Class
LA-1-3, Class LA-1-4, Class LA-1-5 and Class LA-1-6 Uncertificated Interests, in
the case of the Class A-1 Certificates; and to the Class LA-2-1, Class LA-2-2

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

            Such amounts distributed to the Uncertificated Lower-Tier Interests
in respect of principal, interest and reduction of Collateral Support Deficit
with respect to any Distribution Date are referred to herein collectively as the
"Lower-Tier Distribution Amount" and shall be deemed to be deposited by the
Trustee in the Upper-Tier Distribution Account.

            As of any date, payments of principal in respect of the Mortgage
Loans and the Collateral Support Deficit shall be allocated to the
Uncertificated Lower-Tier Interests such that the sum of the principal balance
after application of any Collateral Support Deficit of each Uncertificated
Lower-Tier Interest and the cumulative amount of Collateral Support Deficit
allocated to such Class of Uncertificated Lower-Tier Interests equals the sum of
the Class Principal Balance of the Related Certificates after the application of
any Collateral Support Deficit with respect thereto and the cumulative amount of
Collateral Support Deficit allocated to such Class of Related Certificates;
provided that the Lower-Tier Principal Amount of the Class LA-1-1 Uncertificated
Interest shall be the lesser of $8,849,000 and the excess of the Class Principal
Balance of the Class A-1 Certificates over $262,399,000, the Lower-Tier

LA-1-3 Uncertificated Interest shall be the lesser of $46,791,000 and the excess
of the Class Principal Balance of the Class A-1 Certificates over $169,705,000,
the Lower-Tier Principal Amount of the Class LA-1-4 Uncertificated Interest
shall be the lesser of $44,208,000 and the excess of the Class Principal Balance
of the Class A-1 Certificates over $125,497,000, the Lower-Tier Principal Amount
of the Class LA-1-5 Uncertificated Interest shall be the lesser of $112,901,000
and the excess of the Class Principal Balance of the Class A-1 Certificates over
$12,596,000 and the Lower-Tier Principal Amount of the Class LA-1-6
Uncertificated Interest shall be the lesser of $12,596,000 and the Class
Principal Balance of the Class A-1 Certificates, in each case reduced by any
Collateral Support Deficit allocated to the Class A-1 Certificates, first, to
the Class LA-1-1 Uncertificated Interest, then the Class LA-1-2 Uncertificated
Interest, then the Class LA-1-3 Uncertificated Interest, then the Class LA-1-4
Uncertificated Interest, then the Class LA-1-5 Uncertificated Interest and then
the Class LA-1-6 Uncertificated Interest; and the Lower-Tier Principal Amount of
the Class LA-2-1 Uncertificated Interest shall be the lesser of $24,065,000 and
the excess of the Class Principal Balance of the Class A-2 Certificates over
$509,798,000, the Lower-Tier Principal Amount of the Class LA-2-2 Uncertificated
Interest shall be the lesser of $43,559,000 and the excess of the Class
Principal Balance of the Class A-2 Certificates over $466,239,000 and the
Lower-Tier Principal Amount of the Class LA-2-3 Uncertificated Interest shall be
the lesser of $466,239,000 and the Class Principal Balance of the Class A-2
Certificates, in each case reduced by any Collateral Support Deficit allocated
to the Class A-2 Certificates, first, to the Class LA-2-1 Uncertificated
Interest, then the Class LA-2-2 Uncertificated Interest and then the Class
LA-2-3 Uncertificated Interest. The initial principal balance of each
Uncertificated Lower-Tier Interest equals the respective Original Lower-Tier
Principal Amount. The interest rate with respect to each Uncertificated
Lower-Tier Interest (other than the Class LY Uncertificated Interest) will be
the Weighted Average Net Mortgage Rate.

            Interest Shortfall Amounts allocated to the Class A-X and Class A-SP
Certificates shall be attributed to the Uncertificated Lower-Tier Interests to
the extent of their Related Components, pro rata, based on interest accrued on
such Components. Interest Shortfall Amounts allocated to the Class A-Y
Certificates shall be attributed to the Class A-Y Uncertificated Interest. Any
amounts so allocated shall have the same seniority as interest payments due on
the Class A-X, Class A-Y and Class A-SP Certificates. Prepayment Interest
Shortfalls shall be allocated to each Class of Uncertificated Lower-Tier
Interests pro rata on the basis of their respective interest entitlements.

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

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

          (i) Prepayment Premiums shall be distributed to the Class A-1, Class
     A-2, Class B, Class C, Class D, Class E, Class F, Class G and Class H
     Certificates, in an amount equal to the product of (a) a fraction whose
     numerator is the amount distributed as principal to such Class on such
     Distribution Date, and whose denominator is the total amount distributed as
     principal to the Class A-1, Class A-2, Class 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 and Class Q Certificates on such Distribution Date, (b)
     25% and (c) the total amount of Prepayment Premiums collected during the
     related Due Period. If the Prepayment Premium relates to a Co-op Mortgage
     Loan, the Holders of the Class A-Y Certificates shall be entitled to 70% of
     the portion of the subject Prepayment Premium that remains after the
     distribution contemplated in the immediately preceding sentence. Any
     Prepayment Premiums collected during the related Due Period and remaining
     after the distributions contemplated in the prior two sentences shall be
     distributed to the Holders of the Class A-X Certificates; and

          (ii) Yield Maintenance Charges shall be distributed to the Class A-1,
     Class A-2, Class B, Class C, Class D, Class E, Class F, Class G and Class H
     Certificates, in an amount equal to the product of (a) a fraction whose
     numerator is the amount distributed as principal to such Class on such
     Distribution Date, and whose denominator is the total amount distributed as
     principal to the Class A-1, Class A-2, Class 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 and Class Q Certificates on such Distribution Date, (b)
     the Base Interest Fraction for the related Principal Prepayment and such
     Class of Certificates and (c) the aggregate amount of Yield Maintenance
     Charges collected on such Principal Prepayment during the related Due
     Period. If the Yield Maintenance Charge relates to a Co-op Mortgage Loan,
     the Holders of the Class A-Y Certificates shall be entitled to 60% of the
     portion of the subject Yield Maintenance Charge that remains after the
     distribution contemplated in the immediately preceding sentence. Any Yield
     Maintenance Charges collected during the related Due Period remaining after
     the distributions contemplated in the prior two sentences shall be
     distributed to the Holders of the Class A-X Certificates.

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

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

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

            (f) All distributions made with respect to each Class on each
Distribution Date shall be allocated pro rata among the outstanding Certificates
of such Class based on their respective Percentage Interests. Except as
otherwise specifically provided in Sections 4.01(h), 4.01(i) and 9.01, all such
distributions with respect to each Class on each Distribution Date shall be made
to the Certificateholders of record of the respective Class at the close of
business on the related Record Date and shall be made by wire transfer of
immediately available funds to the account of any such Certificateholder at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided the Trustee with written wiring
instructions no later than the related Record Date (which wiring instructions
may be in the form of a standing order applicable to all subsequent Distribution
Dates) and otherwise by check mailed to the address of such Certificateholder as
it appears in the Certificate Register. The final distribution on each
Certificate (determined without regard to any possible future reimbursement of
Collateral Support Deficit previously allocated to such Certificate) shall be
made in like manner, but only upon presentation and surrender of such
Certificate at the offices of the Trustee or such other location specified in
the notice to Certificateholders of such final distribution.

            Each distribution with respect to a Book-Entry Certificate shall be
paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the
Depositor, the Master Servicers, the Special Servicers, the Underwriters or the
Initial Purchaser shall have any responsibility therefor except as otherwise
provided by this Agreement or applicable law.

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

            Any funds not distributed to any Holder or Holders of Definitive
Certificates of any Class on such Distribution Date because of the failure of
such Holder or Holders to tender their Certificates shall, on such date, be set
aside and held uninvested in trust and credited to the account or accounts of
the appropriate non-tendering Holder or Holders. If any Definitive Certificates
as to which notice has been given pursuant to Section 4.01(h) shall not have
been surrendered for cancellation within six months after the time specified in
such notice, the Trustee shall mail a second notice to the remaining
non-tendering Definitive Certificateholders to surrender their Certificates for
cancellation in order to receive the final distribution with respect thereto. If
within one year after the second notice all such Definitive Certificates shall
not have been surrendered for cancellation, the Trustee, directly or through an
agent, shall take such steps to contact the remaining non-tendering Definitive
Certificateholders concerning the surrender of their Certificates as it shall
deem appropriate. The costs and expenses of holding such funds in trust and of
contacting such Definitive Certificateholders following the first anniversary of
the delivery of such second notice to the non-tendering Certificateholders shall
be paid out of such funds. No interest shall accrue or be payable to any
Definitive Certificateholder on any amount held in trust hereunder by the
Trustee as a result of such Definitive Certificateholder's failure to surrender
its Certificate(s) for final payment thereof in accordance with Section 4.01(h).

            (h) Distributions in reimbursement of Collateral Support Deficit
previously allocated to the Regular Certificates shall be made in the amounts
and manner specified in Section 4.01(a) to the Holders of the respective Class
otherwise entitled to distributions of interest and principal on such Class on
the relevant Distribution Date; provided, however, that all distributions in
reimbursement of Collateral Support Deficit previously allocated to a Class of
Certificates which has since been retired shall be to the prior Holders that
surrendered the Certificates of such Class upon retirement thereof and shall be
made by check mailed to the address of each such prior Holder last shown in the
Certificate Register. Notice of any such distribution to a prior Holder shall be
made in accordance with Section 11.05 at such last address. The amount of the
distribution to each such prior Holder shall be based upon the aggregate
Percentage Interest evidenced by the Certificates surrendered thereby. If the
check mailed to any such prior Holder is returned uncashed, then the amount
thereof shall be set aside and held uninvested in trust for the benefit of such
prior Holder, and the Trustee shall attempt to contact such prior Holder in the
manner contemplated by Section 4.01(i) as if such Holder had failed to surrender
its Certificates.

            (i) Shortfalls in the Available Distribution Amount resulting from
unanticipated Trust Fund indemnification expenses incurred pursuant to Section
6.03 and Section 8.05 shall be allocated to the most subordinate Class of
Certificates then outstanding, until the Class Principal Balance thereof is
reduced to zero, and then is allocated to the next most subordinate Class of
Certificate then outstanding. Such shortfalls shall be allocated to the
Uncertificated Lower-Tier Interests in the same manner as Collateral Support
Deficits.

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

            The Trustee need not deliver to the Depositor, the Master Servicers,
the Special Servicers, the Underwriters, the Rating Agencies or the Controlling
Class Representative any Statement to Certificateholders that has been made
available to such Person via the Trustee's Internet Website as provided below;
provided, the Trustee has no affirmative obligation to discover the identities
of Certificate Owners and need only react to Persons claiming to be Certificate
Owners in accordance with Section 5.06; and provided, further, that during any
period that reports are required to be filed with the Commission with respect to
the Trust pursuant to Section 15(d) of the Exchange Act, each recipient of the
Statement to Certificateholders shall be deemed to have agreed to keep
confidential the information therein until such Statement to Certificateholders
is filed with the Commission, and the Statement to Certificateholders or, if
presented on Trustee's Internet Website, such website, shall bear a legend to
the following effect: No recipient shall use or disclose the information
contained in this statement/report/file in any manner which could result in a
violation of any provision of the Securities Act of 1933 or the Securities
Exchange Act of 1934 or would require registration of any Non-Registered
Certificates pursuant to Section 5 of the Securities Act of 1933.

            On each Distribution Date, the Trustee shall provide or make
available electronically to all Privileged Persons, each file and report
comprising the CMSA Investor Reporting Package and any other report at
Depositor's request, to the extent received by the Trustee since the prior
Distribution Date (or, in the case of the initial Distribution Date, since the
Closing Date); provided that during any period that reports are required to be
filed with the Commission with respect to the Trust pursuant to Section 15(d) of
the Exchange Act, each recipient of such files and reports shall be deemed to
have agreed to keep confidential the information in any such file or report
until such particular file or report is filed with the Commission, and each such
file and report or, if presented on Trustee's Internet Website, such website,
shall bear a legend to the following effect: No recipient shall use or disclose
the information contained in this statement/report/file in any manner which
could result in a violation of any provision of the Securities Act of 1933 or
the Securities Exchange Act of 1934 or would require registration of any
Non-Registered Certificates pursuant to Section 5 of the Securities Act of 1933.

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

            The Trustee shall make available each month, to any interested
party, via the Trustee's Internet Website, in a downloadable format, the
Statement to Certificateholders, Unrestricted Servicer Reports, CMSA Bond Level
File, CMSA Collateral Summary File (which, in each case, if applicable, will
identify each Mortgage Loan by loan number and property name) and, with the
consent or at the direction of the Depositor, such other information regarding
the Certificates and/or the Mortgage Loans as the Trustee may have in its
possession; provided that, unless (i) the particular report or information has
been filed with the Commission pursuant to Section 8.14 or (ii) the Depositor
has notified the Trustee that CSFB LLC has sold the Non-Registered Certificates
to unaffiliated third parties, access to such reports and information on the
Trustee's Internet Website will be protected to the same extent, and limited to
the same Persons, as the Restricted Servicer Reports. After the Trustee shall
have received the notice from the Depositor regarding the sale of the
Non-Registered Certificates, as described in the preceding sentence, the Trustee
shall make the Statement to Certificateholders available to any interested party
via its Internet Website. The Trustee shall make the Restricted Servicer Reports
available each month, via the Trustee's Internet Website only, to any Privileged
Person, upon receipt by the Trustee from such Person of a certification
substantially in the form of Exhibit K-1 or Exhibit K-2, as applicable;
provided, however, that the Trustee shall provide access to such reports to each
party hereto, the Controlling Class Representative, the Mortgage Loan Sellers,
each Underwriter and each Rating Agency without requiring such certification. In
addition, the Trustee is hereby directed and authorized to make available, as a
convenience to interested parties (and not in furtherance of the distribution of
the Prospectus or the Prospectus Supplement under the securities laws), this
Agreement, the Prospectus and the Prospectus Supplement via the Trustee's
Internet Website. The Trustee will make no representations or warranties as to
the accuracy or completeness of such documents and will assume no responsibility
therefor.

            The Trustee's Internet Website shall be located at
"www.ctslink.com/cmbs" or at such other address as shall be specified by the
Trustee from time to time in the Statement to Certificateholders and in one or
more written notices delivered to the other parties hereto, the Controlling
Class Representative (if any), the Certificateholders and the Rating Agencies.
In connection with providing access to the Trustee's Internet Website, the
Trustee may require registration and the acceptance of a disclaimer. The Trustee
shall not be liable for the dissemination of information in accordance with this
Agreement.

            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 Statement to Certificateholders 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) By 12:00 p.m. New York City time on the second Business Day
following each Determination Date, each Master Servicer shall deliver to the
Trustee the CMSA Loan Periodic Update File and supplemental reports reflecting
information as of the close of business on the last day of the Collection Period
with respect to the Mortgage Loans for which it acts as Master Servicer, in a
mutually agreeable electronic format. Such CMSA Loan Periodic Update File and
any written information supplemental thereto shall include such information with
respect to the Mortgage Loans for which it acts as Master Servicer that is
reasonably required by the Trustee for purposes of making the calculations and
preparing the reports for which the Trustee is responsible pursuant to Section
4.01, this Section 4.02, Section 4.04 or any other section of this Agreement, as
set forth in reasonable written specifications or guidelines issued by the
Trustee from time to time. Such information may be delivered by a Master
Servicer to the Trustee by telecopy or in such electronic or other form as may
be reasonably acceptable to the Trustee and such Master Servicer.

            Notwithstanding the foregoing, because each 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 in April 2003 will be based solely upon information generated from
actual collections received by the applicable Master Servicer and from
information the Depositor delivers or causes to be delivered to the applicable
Master Servicer (including but not limited to information prepared by third
party servicers of the Mortgage Loans with respect to the period prior to the
Closing Date). The applicable Special Servicer shall from time to time (and, in
any event, as may be reasonably required by the applicable Master Servicer)
provide such Master Servicer with such information in its possession regarding
the Specially Serviced Mortgage Loans for which it acts as Special Servicer and
the related REO Properties as may be necessary for such Master Servicer to
prepare each report and any supplemental information to be provided by such
Master Servicer to the Trustee.

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

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

            Section 4.03 P&I Advances

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

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

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

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

            Section 4.04 Allocation of Collateral Support Deficit

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

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

            (c) With respect to any Distribution Date, any Collateral Support
Deficit allocated to a Class of Certificates pursuant to Section 4.04(b) with
respect to such Distribution Date shall reduce the Lower-Tier Principal Amounts
of the Related Uncertificated Lower-Tier Interest with respect thereto as a
write-off (in the case of the Class LA-1-1, Class LA-1-2, Class LA-1-3, Class
LA-1-4, Class LA-1-5 and Class LA-1-6 Uncertificated Interests, to each such
Uncertificated Lower-Tier Interest, in that order; and in the case of the Class
LA-2-1, Class LA-2-2 and Class LA-2-3 Uncertificated Interests, to each such
Uncertificated Lower-Tier Interest, in that order. Section 4.05 Calculations

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

            Section 4.06 Grantor Trust Reporting

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

                                   ARTICLE V

                                THE CERTIFICATES

            Section 5.01 The Certificates

            (a) The Certificates shall consist of 24 Classes with the following
respective alphabetic or alphanumeric Class designations: "A-X," "A-CP," "A-Y,"
"A-1," "A-2," "B," "C," "D," "E," "F," "G," "H," "J," "K," "L," "M," "N," "O,"
"P," "Q," "R," "LR" and "V," respectively. Any reference in any other section or
subsection of this Agreement to any Certificate or Certificates preceded by a
Class designation shall be to a Certificate or Certificates of the Class so
designated in this Section 5.01(a).

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

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

            Section 5.02 Registration of Transfer and Exchange of Certificates

            (a) At all times during the term of this Agreement, there shall be
maintained at the office of the Certificate Registrar a Certificate Register in
which, subject to such reasonable regulations as the Certificate Registrar
(located as of the Closing Date at Wells Fargo Center, Sixth Street 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 Servicers and the Special Servicers 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 Depository
or, in the case of a Definitive Certificate issued with respect to a Global
Certificate, any transfer of such Certificate to the applicable Certificate
Owner in accordance with Section 5.03(c)), then the Certificate Registrar shall
refuse to register such transfer unless it receives (and, upon receipt, may
conclusively rely upon) either: (i) a certificate from the Certificateholder
desiring to effect such transfer substantially in the form attached hereto as
Exhibit F-1A; or (ii) a certificate from the Certificateholder desiring to
effect such transfer substantially in the form attached hereto as Exhibit F-1B
and a certificate from such Certificateholder's prospective Transferee
substantially in the form attached hereto either as Exhibit F-2A or as Exhibit
F-2B; or (iii) an Opinion of Counsel satisfactory to the Trustee to the effect
that such transfer may be made without registration under the Securities Act
(which Opinion of Counsel shall not be an expense of the Trust or of the
Depositor, the Master Servicers, the Special Servicers, the Trustee, any Fiscal
Agent or the Certificate Registrar in their respective capacities as such),
together with the written certification(s) as to the facts surrounding such
transfer from the Certificateholder desiring to effect such transfer and/or such
Certificateholder's prospective Transferee on which such Opinion of Counsel is
based.

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

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

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

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

            Notwithstanding the preceding paragraph, following the Release Date,
any interest in the Regulation S Global Certificate with respect to the Class
A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L or Class M
Certificates may be transferred (without delivery of any certificate described
in the first sentence of the preceding paragraph) to any Person who takes
delivery in the form of a beneficial interest in the Rule 144A Global
Certificate for the same Class as such Regulation S Global Certificate upon
delivery to the Certificate Registrar and the Trustee of (i) a certificate from
the Certificate Owner desiring to effect such transfer substantially in the form
attached hereto as Exhibit F-1C and a certificate from such Certificate Owner's
prospective Transferee substantially in the form attached hereto as Exhibit F-2C
and (ii) such written orders and instructions as are required under the
applicable procedures of the Depository, Clearstream and/or Euroclear to direct
the Trustee to debit the account of a Depository Participant by a denomination
of interests in such Regulation S Global Certificate, and credit the account of
a Depository Participant by a denomination of interests in such Rule 144A Global
Certificate, that is equal to the denomination of beneficial interests in the
Class A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L or
Class M Certificates to be transferred. Upon delivery to the Trustee of such
certifications and such orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of the Depository, shall reduce the
denomination of the Regulation S Global Certificate with respect to the Class
A-X, Class A-SP, Class F, Class G, Class H, Class J, Class K, Class L or Class M
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 or Class M Certificates may be transferred by any Certificate
Owner holding such interest to any Person who takes delivery in the form of a
Definitive Certificate of the same Class as such Global Certificate upon
delivery to the Certificate Registrar and the Trustee of (i) such certifications
and/or opinions as are contemplated by the second paragraph of this Section
5.02(b) and (ii) such written orders and instructions as are required under the
applicable procedures of the Depository, Clearstream and/or Euroclear to direct
the Trustee to debit the account of a Depository Participant by a denomination
of interests in such Global Certificate. Upon delivery to the Certificate
Registrar of the certifications and/or opinions contemplated by the second
paragraph of this Section 5.02(b), the Trustee, subject to and in accordance
with the applicable procedures of the Depository, shall reduce the denomination
of the subject Global Certificate, and cause a Definitive Certificate of the
same Class as such Global Certificate, and in a denomination equal to the
reduction in the denomination of such Global Certificate, to be executed,
authenticated and delivered in accordance with this Agreement to the applicable
Transferee.

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

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

            Except in connection with the initial issuance of the Certificates
or any transfer of a Non-Registered Certificate by the Depositor or an Affiliate
of the Depositor or, in the case of a Global Certificate, any transfer of such
Certificate to a successor Depository or, in the case of a Definitive
Certificate issued with respect to a Global Certificate, any transfer of such
Certificate to the applicable Certificate Owner in accordance with Section
5.03(c), the Certificate Registrar shall refuse to register the transfer of a
Non-Registered Certificate unless it has received from the prospective
Transferee any of the following: (i) a certification to the effect that such
prospective Transferee is not a Plan and is not directly or indirectly
purchasing such Certificate or interest therein on behalf of, as named fiduciary
of, as trustee of, or with assets of a Plan; or (ii) except in the case of a
Class R, Class LR or Class V Certificate, a certification to the effect that the
purchase and continued holding of such Certificate by such prospective
Transferee is exempt from the prohibited transaction provisions of Section 406
and 407 of ERISA and Section 4975 of the Code by reason of Sections I and III of

the aggregate unamortized principal of all the Mortgage Loans determined as of
the Closing Date, or by any Affiliate of such Person, and (Z) agrees that it
will obtain from each of its Transferees a written representation that such

Transferee will obtain from each of its Transferees that are Plans a similar
written representation regarding satisfaction of the requirements of the

of a Class R, Class LR or Class V Certificate, a certification of facts and an
Opinion of Counsel (which Opinion of Counsel shall not be an expense of the

the reasonable satisfaction of the Trustee that such transfer will not result in
a violation of Section 406 or 407 of ERISA or Section 4975 of the Code or
similar violation of Similar Law or result in the imposition of an excise tax
under Section 4975 of the Code or Similar Law. It is hereby acknowledged that
the form of certification attached hereto as Exhibit G-1 is acceptable for
purposes of the preceding sentence.

            Except in connection with the initial issuance of the Certificates
or any transfer of an interest in a Book-Entry Non-Registered Certificate by the
Depositor or an Affiliate of the Depositor, the Certificate Owner desiring to
effect a transfer of an interest in a Book-Entry Non-Registered Certificate
shall obtain from its prospective Transferee one of the following: (i) a
certification to the effect that such prospective Transferee is not a Plan and
is not directly or indirectly purchasing such interest in such Certificate on
behalf of, as named fiduciary of, as trustee of, or with assets of a Plan; or

4975 of the Code by reason of Sections I and III of Prohibited Transaction Class
Exemption 95-60 (or similar exemption under Similar Law); or (iii) if such

such Plan (X) is an accredited investor as defined in Rule 501(a)(1) of
Regulation D of the Securities Act, (Y) is not sponsored (within the meaning of
Section 3(16)(B) of ERISA) by the Trustee, the Depositor, any Mortgage Loan
Seller, either Master Servicer, either Special Servicer, any Sub-Servicer or any
Borrower with respect to Mortgage Loans constituting 5% of the aggregate
unamortized principal of all the Mortgage Loans determined as of the Closing
Date, or by any Affiliate of such Person, and (Z) agrees that it will obtain
from each of its Transferees a written representation that such Transferee, if a
Plan, satisfies the requirements of the immediately preceding clauses (iii)(X)
and (iii)(Y), together with a written agreement that such Transferee will obtain
from each of its Transferees that are Plans a similar written representation
regarding satisfaction of the requirements of the immediately preceding clauses
(iii)(X) and (iii)(Y); or (iv) except in the case of a Class R, Class LR or
Class V Certificate, a certification of facts and an Opinion of Counsel to the
effect that such transfer will not result in a violation of Section 406 or 407
of ERISA or Section 4975 of the Code or similar violation of Similar Law or
result in the imposition of an excise tax under Section 4975 of the Code or
Similar Law. It is hereby acknowledged that the form of certification attached
hereto as Exhibit G-2 is acceptable for purposes of the preceding sentence.

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

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

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

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

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

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

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

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

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

          (iii) The Trustee shall make available to the IRS and to those Persons
     specified by the REMIC Provisions all information furnished to it by the
     other parties hereto necessary to compute any tax imposed as a result of
     the Transfer of an Ownership Interest in a Class R or Class LR Certificate
     to any Person who is a Disqualified Organization, including the information
     described in Treasury Regulations Sections 1.860D-1(b)(5) and
     1.860E-2(a)(5) with respect to the "excess inclusions" for the Upper-Tier
     REMIC and the Lower-Tier REMIC, and each of the other parties hereto shall
     furnish to the Trustee all information in its possession necessary for the
     Trustee to discharge such obligation. The Person holding such Ownership
     Interest shall be responsible for the reasonable compensation of the
     Trustee for providing such information.

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

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

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

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

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

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

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

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

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

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

            Section 5.03 Book-Entry Certificates

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

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

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

            Section 5.04 Mutilated, Destroyed, Lost or Stolen Certificates

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

            Section 5.05 Persons Deemed Owners

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

            Section 5.06 Certification by Certificateholders and Certificate
Owners

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

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

      THE DEPOSITOR, THE MASTER SERVICERS AND THE SPECIAL SERVICERS Section

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

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

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

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

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

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

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

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

            Section 6.04 Resignation of the Master Servicers or the Special
Servicers

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

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

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

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

            Each Master Servicer and each Special Servicer shall afford the
Depositor, the Trustee, the Controlling Class Representative 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
with respect to any of the Mortgage Loans and, at mutually agreeable times,
access to such of its officers as are responsible for such obligations
;provided, that the Controlling Class Representative shall have additional
access to information as provided in Section 3.15(c) and Section 8.12(b) hereof.
Upon reasonable request, each Master Servicer and each Special Servicer shall
furnish the Depositor and the Trustee with its most recent publicly available
annual audited financial statements (or, if not available, the most recent
publicly available audited annual financial statements of its corporate parent)
and such other information as is publicly available regarding its business,
affairs, property and condition, financial or otherwise; provided that neither
the Depositor nor the Trustee may disclose the contents of such financial
statements or other information to non-affiliated third parties (other than
accountants, attorneys, financial advisors and other representatives retained to
help it evaluate such financial statements or other information), unless it is
required to do so under applicable securities laws or is otherwise compelled to
do so as a matter of law. Each Master Servicer and each Special Servicer may
affix to any such information described in this Section 6.05 provided by it any
disclaimer it deems appropriate in its reasonable discretion. The Depositor may,
but is not obligated to, enforce the obligations of the Master Servicers and
Special Servicers hereunder and may, but is not obligated to, perform, or cause
a designee to perform, any defaulted obligation of the Master Servicers or the
Special Servicers hereunder or exercise the rights of the Master Servicers or
the Special Servicers hereunder; provided, however, that neither of the Master
Servicers nor the Special Servicers shall be relieved of any of its obligations
hereunder by virtue of such performance by the Depositor or its designee. The
Depositor shall not have any responsibility or liability for any action or
failure to act by the Master Servicers or the Special Servicers and is not
obligated to supervise the performance of the Master Servicers or the Special
Servicers under this Agreement or otherwise.

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

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

                                   ARTICLE VII

                                     DEFAULT

            Section 7.01 Events of Default

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

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

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

               (iii) any failure by a Master Servicer to remit to the Trustee
          for deposit into the Distribution Account, on any P&I Advance Date,
          the full amount of P&I Advances required to be made 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 a Master Servicer to timely make any
          Servicing Advance required to be made by it hereunder, which Servicing
          Advance remains unmade for a period of three Business Days following
          the date on which notice shall have been given to such Master Servicer
          by the Trustee as provided in Section 3.11(f); or

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

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

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

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

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

               (x) a Master Servicer or a 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 Moody's
          to the effect that the continuation of a Master Servicer or a Special
          Servicer in such capacity would, in and of itself, result, or has
          resulted, in a qualification, downgrade or withdrawal of one or more
          ratings assigned by Moody's to the Certificates; or

               (xii) Moody's places the rating of any Class of Certificates on
          "watchlist" status for possible ratings downgrade or withdrawal citing
          servicing concerns with respect to a Master Servicer or a Special
          Servicer as the sole or a contributory factor in such rating action,
          and Moody's has not removed such rating from "watchlist" status within
          60 days thereafter or stated that servicing is no longer a
          contributory factor; or

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

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

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

            Section 7.02  Trustee to Act; Appointment of Successor

            On and after the time a Master Servicer or a Special Servicer
resigns pursuant to Section 6.04(a) or receives a notice of termination pursuant
to Section 7.01, the Trustee shall be the successor in all respects to such
Master Servicer or such Special Servicer, as the case may be, in its capacity as
such under this Agreement and the transactions set forth or provided for herein
and shall be subject to all the responsibilities, duties and liabilities
relating thereto and arising thereafter placed on such Master Servicer or such
Special Servicer, as the case may be, by the terms and provisions hereof,
including, if a Master Servicer is the resigning or terminated party, such
Master Servicer's obligation to make Advances; provided, however, that any
failure to perform such duties or responsibilities caused by a Master Servicer's
or a Special Servicer's, as the case may be, failure to cooperate or to provide
information or monies as required by Section 7.01 shall not be considered a
default by the Trustee hereunder. Neither the Trustee nor any other successor
shall be liable for any of the representations and warranties of the resigning
or terminated party or for any losses incurred by the resigning or terminated
party pursuant to Section 3.06 hereunder nor shall the Trustee or any other
successor be required to purchase any Mortgage Loan hereunder. As compensation
therefor, the Trustee shall be entitled to all fees and other compensation
(subject to Section 3.11) which the resigning or terminated party would have
been entitled to for future services rendered if the resigning or terminated
party had continued to act hereunder. Notwithstanding the above, if it is
unwilling to so act, the Trustee may (and, if it is unable to so act, or if the
Trustee is not approved as an acceptable master servicer or special servicer, as
the case may be, by each Rating Agency, or if the Holders of Certificates
entitled to a majority of all the Voting Rights 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 a Master Servicer or a Special Servicer, as the case may be,
hereunder in the assumption of all or any part of the responsibilities, duties
or liabilities of such Master Servicer or such Special Servicer, as the case may
be, hereunder; provided, however, that such appointment does not result in an
Adverse Rating Event with respect to any Class of Rated Certificates (as
confirmed in writing to the Trustee by each Rating Agency). No appointment of a
successor to a Master Servicer or a Special Servicer hereunder shall be
effective until the assumption by such successor of all its responsibilities,
duties and liabilities hereunder, and pending such appointment and assumption,
the Trustee shall act in such capacity as hereinabove provided. In connection
with any such appointment and assumption, the Trustee may make such arrangements
for the compensation of such successor out of payments on the Mortgage Loans or
otherwise as it and such successor shall agree; provided, however, that no such
compensation shall be in excess of that permitted the resigning or terminated
party hereunder. The Depositor, the Trustee, such successor and each other party
hereto shall take such action, consistent with this Agreement, as shall be
necessary to effectuate any such succession.

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

            Section 7.03  Notification to Certificateholders

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

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

            Section 7.04  Waiver of Events of Default

            The Holders of Certificates representing at least 66-2/3% of the
Voting Rights allocated to each Class of Certificates affected by any Event of
Default hereunder may waive such Event of Default; provided that an Event of
Default under clause (i), clause (ii), clause (iii), clause (xi), clause (xii)
or clause (xiii) of Section 7.01(a) may be waived only by all of the
Certificateholders of the affected Classes. Upon any such waiver of an Event of
Default, and payment to the Trustee of all reasonable costs and expenses
incurred by the Trustee in connection with such default prior to its waiver
(which costs shall be paid by the party requesting such waiver), such Event of
Default shall cease to exist and shall be deemed to have been remedied for every
purpose hereunder. No such waiver shall extend to any subsequent or other Event
of Default or impair any right consequent thereon except to the extent expressly
so waived. Notwithstanding any other provisions of this Agreement, for purposes
of waiving any Event of Default pursuant to this Section 7.04, Certificates
registered in the name of the Depositor or any Affiliate of the Depositor shall
be entitled to the same Voting Rights with respect to the matters described
above as they would if registered in the name of any other Person.

            Section 7.05  Additional Remedies of Trustee Upon Event of Default

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

                                  ARTICLE VIII

                                   THE TRUSTEE

            Section 8.01 Duties of Trustee

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

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

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

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

                  (ii) The Trustee shall not be liable for an error of judgment
            made in good faith by a Responsible Officer or Responsible Officers
            of the Trustee, unless it shall be proved that the Trustee was
            negligent in ascertaining the pertinent facts.

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

                  (iv) The Trustee shall not be required to take action with
            respect to, or be deemed to have notice or knowledge of, any default
            or Event of Default (except an Event of Default under Section
            7.01(a)(xi) or Section 7.01(a)(xii) or a 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 re-recording, refiling or
            redepositing of any thereof, (B) to cause the maintenance of any
            insurance, and (C) to confirm or verify the truth, accuracy or
            contents of any reports or certificates of a Master Servicer, a
            Special Servicer, any actual or prospective or any Certificateholder
            or Certificate Owner or either Rating Agency, delivered to the
            Trustee pursuant to this Agreement reasonably believed by the
            Trustee to be genuine and without error and to have been signed or
            presented by the proper party or parties.

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

            Section 8.02  Certain Matters Affecting the Trustee

            Except as otherwise provided in Section 8.01:

                  (i) the Trustee may rely upon and shall be protected in acting
            or refraining from acting upon any resolution, Officers'
            Certificate, certificate of auditors or any other certificate,
            statement, instrument, opinion, report, notice, request, consent,
            order, appraisal, bond or other paper or document reasonably
            believed by it to be genuine and without error and to have been
            signed or presented by the proper party or parties;

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

                  (iii) the Trustee shall be under no obligation to exercise any
            of the trusts or powers vested in it by this Agreement or to make
            any investigation of matters arising hereunder or to institute,
            conduct or defend any litigation hereunder or in relation hereto at
            the request, order or direction of any of the Certificateholders,
            unless (in the Trustee's reasonable opinion) such Certificateholders
            shall have offered to the Trustee reasonable security or indemnity
            against the costs, expenses and liabilities which may be incurred
            therein or thereby; the Trustee shall not be required to expend or
            risk its own funds or otherwise incur any financial liability in the
            performance of any of its duties hereunder, or in the exercise of
            any of its rights or powers, if it shall have reasonable grounds for
            believing that repayment of such funds or adequate indemnity against
            such risk or liability is not reasonably assured to it; provided,
            however, that nothing contained herein shall relieve the Trustee of
            the obligation, upon the occurrence of an Event of Default which has
            not been waived or cured, to exercise such of the rights and powers
            vested in it by this Agreement, and to use the same degree of care
            and skill in their exercise as a prudent man would exercise or use
            under the circumstances in the conduct of his own affairs;

                  (iv) neither the Trustee nor any Fiscal Agent appointed
            thereby shall be personally liable for any action reasonably taken,
            suffered or omitted by it in good faith and believed by it to be
            authorized or within the discretion or rights or powers conferred
            upon it by this Agreement;

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

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

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

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

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

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

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

            Section 8.04 Trustee and Fiscal Agent May Own Certificates

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

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

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

            (b) The Trustee and any director, officer, employee or agent of the
Trustee shall be entitled to be indemnified and held harmless out of the Trust
Fund for and against any loss, liability, claim or expense (including costs and
expenses of litigation, and of investigation, counsel fees, damages, judgments
and amounts paid in settlement) arising out of, or incurred in connection with,
this Agreement, the Certificates, the Mortgage Loans (unless it incurs any such
expense or liability in the capacity of 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 Master Servicer or Special
Servicer, as the case may be) or any act or omission of the Trustee relating to
the exercise and performance of any of the powers and duties of the Trustee
hereunder, if (but only if) such loss, liability, claim or expense constitutes
an "unanticipated expense" within the meaning of Treasury Regulations Section
1.860G-1(b)(3)(ii); provided, however, that neither the Trustee nor any of the
other above specified Persons shall be entitled to indemnification pursuant to
this Section 8.05(b) for (1) allocable overhead, such as costs for office space,
office equipment, supplies and related expenses, employee salaries and related
expenses and similar internal costs and expenses, (2) any expense or liability
specifically required to be borne thereby pursuant to the terms hereof or (3)
except as provided in Article X, 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 Master Servicer and each Special Servicer shall indemnify
the Trustee and any Fiscal Agent for and hold each of them harmless against any
loss, liability, claim or expense that is a result of such Master Servicer's or
such Special Servicer's, as the case may be, negligent acts or omissions in
connection with this Agreement, including the negligent use by such Master
Servicer or such Special Servicer, as the case may be, of any powers of attorney
delivered to it by the Trustee pursuant to the provisions hereof and the
Mortgage Loans serviced by such Master Servicer or such Special Servicer, as the
case may be; provided, however, that, if the Trustee has been reimbursed for
such loss, liability, claim or expense pursuant to Section 8.05(b), or any
Fiscal Agent has been reimbursed for such loss, liability, claim or expense
pursuant to Section 8.13, then the indemnity in favor of such Person provided
for in this Section 8.05(c) with respect to such loss, liability, claim or
expense shall be for the benefit of the Trust.

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

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

            Section 8.06  Eligibility Requirements for Trustee

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

            Section 8.07  Resignation and Removal of Trustee

            (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Depositor, the
Master Servicers, the Special Servicers, the Certificateholders and any B Loan
Holder. Upon receiving such notice of resignation, the Depositor shall promptly
appoint a successor trustee meeting the eligibility requirements of Section 8.06
by written instrument, in duplicate, which instrument shall be delivered to the
resigning Trustee and to the successor trustee. A copy of such instrument shall
be delivered to other parties hereto and to the Certificateholders and any B
Loan Holders by the Depositor. If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

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

            (c) The Holders of Certificates entitled to not less than 51% of the
Voting Rights may at any time remove the Trustee and appoint a successor trustee
by written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized, one complete set of which instruments
shall be delivered to the Depositor (with copies to the Master Servicers and the
Special Servicers), one complete set to the Trustee so removed and one complete
set to the successor so appointed. All expenses incurred by the Trustee in
connection with its transfer of the Mortgages Files to a successor trustee
following the removal of the Trustee without cause pursuant to this Section
8.07(c), shall be reimbursed to the removed Trustee within 30 days of demand
therefor, such reimbursement to be made by the Certificateholders that
terminated the Trustee. A copy of such instrument shall be delivered to the
other parties hereto and to the remaining Certificateholders and B Loan Holders
by the successor so appointed.

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

            Section 8.08  Successor Trustee

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

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

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

            Section 8.09  Merger or Consolidation of Trustee

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

            Section 8.10  Appointment of Co-Trustee or Separate Trustee

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

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

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

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

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

            Section 8.11  Appointment of Custodians

            The Trustee may, with the consent of the Master Servicers, 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 if the Custodian is
an Affiliate of the Trustee such consent of the Master Servicers need not be
obtained and the Trustee shall inform the Master Servicers of such appointment.
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, any Mortgage Loan
Seller or any Affiliate of the Depositor or any Mortgage Loan Seller, and shall
have in place a fidelity bond and errors and omissions policy, each in such form
and amount as is customarily required of custodians acting on behalf of Freddie
Mac or Fannie Mae. Each Custodian shall be subject to the same obligations,
standard of care, protection and indemnities as would be imposed on, or would
protect, the Trustee hereunder in connection with the retention of Mortgage
Files directly by the Trustee. The appointment of one or more Custodians shall
not relieve the Trustee from any of its obligations hereunder, and the Trustee
shall remain responsible for all acts and omissions of any Custodian.

            Section 8.12  Access to Certain Information

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

            (b) The Trustee shall maintain at its offices and, upon reasonable
prior written request and during normal business hours, shall make available for
review by the Depositor, the Underwriters, the Rating Agencies, the Controlling
Class Representative and, subject to the succeeding paragraph, any
Certificateholder, each B Loan Holder and its designees, Certificate Owner or
Person identified to the Trustee as a prospective Transferee of a Certificate or
an interest therein, originals and/or copies of the following items (to the
extent such items were prepared by or delivered to the Trustee): (i) the
Prospectus, the Confidential Offering Circular and any other disclosure document
relating to the Certificates, in the form most recently provided to the Trustee
by the Depositor or by any Person designated by the Depositor; (ii) this
Agreement, each Sub-Servicing Agreement delivered to the Trustee since the
Closing Date and any amendments and exhibits hereto or thereto; (iii) all
Statement to Certificateholders and any files and reports comprising the CMSA
Investor Reporting Package actually delivered or otherwise made available to
Certificateholders pursuant to Section 4.02(a) since the Closing Date; (iv) all
Annual Performance Certifications delivered by the Master Servicers and the
Special Servicers, respectively, to the Trustee since the Closing Date; (v) all
Annual Accountants' Reports caused to be delivered by the Master Servicers and
the Special Servicers, respectively, to the Trustee since the Closing Date; (vi)
the most recent inspection report prepared by the Master Servicers or the
Special Servicers and delivered to the Trustee in respect of each Mortgaged
Property pursuant to Section 3.12(a) or this Section 8.12(b); (vii) the most
recent quarterly and annual operating statement and rent roll (except with
respect to Co-op Mortgage Loans) of each related Mortgaged Property and
financial statements of the related Borrower collected by the Master Servicers
or the Special Servicers and delivered to the Trustee pursuant to Section
3.12(b) or this Section 8.12(b); (viii) any and all notices and reports
delivered to the Trustee with respect to any Mortgaged Property as to which the
environmental testing contemplated by Section 3.09(c) revealed that neither of
the conditions set forth in clauses (i) and (ii) of the first sentence thereof
was satisfied; (ix) each of the Mortgage Files, including any and all
modifications, waivers and amendments of the terms of a Mortgage Loan entered
into or consented to by a Master Servicer or a Special Servicer and delivered to
the Trustee pursuant to Section 3.20; (x) the most recent Appraisal for each
Mortgage Loan and REO Property that has been delivered to the Trustee (all
Appraisals of Mortgaged Properties and/or REO Properties shall be delivered to
the Trustee by the applicable Master Servicer or Special Servicer, as
applicable, promptly following their having been obtained or formulated); (xi)
any and all Officer's Certificates and other evidence delivered to or by the
Trustee to support its, a Master Servicer's, a Special Servicer's or any Fiscal
Agent's, as the case may be, determination that any Advance was (or, if made,
would be) a Nonrecoverable Advance; (xii) a current report from the Trustee
listing all outstanding exceptions to the Mortgage File review conducted
pursuant to Section 2.02; and (xiii) any other information that may be necessary
to satisfy the requirements of subsection (d)(4)(i) of Rule 144A under the
Securities Act. The Trustee shall provide copies of any and all of the foregoing
items upon request of any of the parties set forth in the previous sentence;
however, except in the case of the Rating Agencies, the Trustee shall be
permitted to require payment of a sum sufficient to cover the reasonable costs
and expenses of providing such copies. If necessary, the Trustee shall request
from the Master Servicers, and within a reasonable period following its receipt
of such request, and the Master Servicers shall deliver, copies of the items
listed in clauses (vi) and (vii) above to the Trustee.

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

            In addition, each Master Servicer and each Special Servicer shall,
upon reasonable prior written request and during normal business hours, make
available for review by the Controlling Class Representative, any additional
information in respect of its rights and obligations hereunder that such
Controlling Class Representative may reasonably request.

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

            Section 8.13  Appointment of Fiscal Agent

            (a) Insofar as the Trustee would not otherwise satisfy the rating
requirements of Section 8.06, the Trustee may appoint, at the Trustee's own
expense, a Fiscal Agent for purposes of making Advances hereunder that are
otherwise required to be made by the Trustee. Any Fiscal Agent shall at all
times maintain a long-term unsecured debt rating of no less than "Aa3" from
Moody's and "AA" from S&P (or, in the case of either Rating Agency, such lower
rating as will not result in an Adverse Rating Event with respect to any Class
of Rated Certificates (as confirmed in writing to the Trustee and the Depositor
by such Rating Agency)). Any Person so appointed by the Trustee pursuant to this
Section 8.13(a) shall become the Fiscal Agent on the date as of which the
Trustee and the Depositor have received: (i) if the long-term unsecured debt of
the designated Person is not rated at least "Aa3" by Moody's and "AA" by S&P,
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 a successor Master
Servicer or otherwise, and has failed to do so in accordance with the terms
hereof, the Fiscal Agent (if any) shall make such Advance when and as required
by the terms of this Agreement on behalf the Trustee as if such Fiscal Agent
were the Trustee hereunder. To the extent that the Fiscal Agent (if any) makes
an Advance pursuant to this Section 8.13 or otherwise pursuant to this
Agreement, the obligations of the Trustee under this Agreement in respect of
such Advance shall be satisfied.

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

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

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

            Section 8.14 Filings with the Securities and Exchange Commission

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

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

                  (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) (in each case to the extent
            that a Responsible Officer of the Trustee has actual knowledge
            thereof), (B) cooperate with the Depositor in obtaining all
            necessary information in order to enable the Depositor to prepare a
            Current Report on Form 8-K reporting any such matter in accordance
            with the Exchange Act, the rules and regulations promulgated
            thereunder and applicable "no-action letters" issued by the
            Commission, and (C) execute and promptly file with the Commission
            any such Current Report on Form 8-K prepared by or on behalf of the
            Depositor and delivered to the Trustee;

                  (iii) 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 Servicers and the Special Servicers for such
            fiscal year, and which shall further include such certification(s)
            as may be required under the Sarbanes-Oxley Act of 2002 and any
            rules promulgated by, or interpretive guidance from, the Commission
            (such certification(s), individually and collectively, insofar as
            they are required to be part of any particular Annual Report on Form
            10-K, a "Sarbanes-Oxley Certification") (which Sarbanes-Oxley
            Certifications shall be signed by the party or parties contemplated
            by this Section 8.14);

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

            (b) The Form 10-K 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 Servicers, the Special Servicers and the Trustee (each, a "Performing
Party") shall provide to the Person who signs the Sarbanes-Oxley Certification
(the "Certifying Person") a certification (each, a "Performance Certification"),
in the form set forth on Exhibit O hereto (with respect to the Master Servicers
and the Trustee) or in the form set forth on Exhibit A to Exhibit O hereto (with
respect to the Special Servicers), as applicable, on which the Certifying
Person, the Depositor (if the Certifying Person is an individual), and the
Depositor's partner, representative, Affiliate, member, manager, director,
officer, employee or agent (collectively with the Certifying Person,
"Certification Parties") can rely. The Trustee's certification with respect to
items 1 through 3 of Exhibit O hereto shall relate to distribution information,
and each Master Servicer's certification with respect to items 4 and 5 of
Exhibit O 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
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) If as of the beginning of any fiscal year for the Trust (other
than fiscal year 2003), the Public Certificates are held (directly or, in the
case of Public Certificates held in book-entry form, through the Depository) by
less than 300 Holders and/or Depository Participants having accounts with the
Depository, the Trustee shall, in accordance with the Exchange Act and the rules
and regulations promulgated thereunder, timely file a Form 15 with respect to
the Trust notifying the Commission of the suspension of the reporting
requirements under the Exchange Act.

            (d) 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.

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

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

                                   ARTICLE IX

                                   TERMINATION

            Section 9.01  Termination Upon Repurchase or Liquidation of All
                          Mortgage Loans

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

            (b) Any single Controlling Class Certificateholder or group of
Controlling Class Certificateholders, the Co-op Master Servicer, the Co-op
Special Servicer, the General Master Servicer or the General Special Servicer,
in that order of preference, may at its option elect to purchase all the
Mortgage Loans and each REO Property remaining in the Trust Fund as contemplated
by clause (i) of Section 9.01(a) by giving written notice to the other parties
hereto (and, in the case of an election by a Master Servicer or Special
Servicer, to the Holders of each Controlling Class) no later than 60 days prior
to the anticipated date of purchase; provided, however, that the aggregate
Stated Principal Balance of the Mortgage Pool at the time of such election is
less than 1.0% of the Initial Pool Balance; and provided, further, that within
30 days after written notice of such election is so given, no Person with a
higher right of priority to make such an election does so; and provided,
further, that if more than one Controlling Class Certificateholder or group of
Controlling Class Certificateholders desire to purchase all of the Mortgage
Loans and any REO Properties, preference shall be given to the Certificateholder
or group of Certificateholders with the largest Percentage Interest in the
Controlling Class. Notwithstanding the foregoing, if any party other than the
Co-op Master Servicer exercises such purchase option, then the Co-op Master
Servicer will be entitled to purchase the remaining Co-op Mortgage Loans and any
related REO Properties, in which case, such other party will purchase only the
Mortgage Loans and any REO Properties that are not being purchased by the Co-op
Master Servicer. If the Trust is to be terminated in connection with the
purchase of all the Mortgage Loans and each REO Property remaining in the Trust
Fund by a Master Servicer, a Special Servicer or any Controlling Class
Certificateholder(s), such Person(s) shall: deliver to the applicable Master
Servicer for deposit (or, if the applicable Master Servicer is the purchaser, it
shall deposit) in a 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 applicable Master
Servicer shall transfer to the Lower-Tier Distribution Account all amounts
required to be transferred thereto 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 Mortgage
Loans and shall execute all assignments, endorsements and other instruments
furnished to it by the purchasing party as shall be necessary to effectuate
transfer of the Mortgage Loans and REO Properties to the purchasing party (or
its designee).

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

            (c) Notice of any termination shall be given promptly by the Trustee
by letter to Certificateholders and each B Loan Holder mailed (x) if such notice
is given in connection with the purchase of all the Mortgage Loans and each REO
Property remaining in the Trust Fund by the Master Servicers, the Special
Servicers or any Certificateholder(s) of the Controlling Class, not earlier than
the 15th day and not later than the 25th day of the month next preceding the
month of the final distribution on the Certificates and (y) otherwise during the
month of such final distribution on or before the Master Servicer Remittance
Date in such month, in any event specifying (i) the Distribution Date upon which
the Trust Fund will terminate and final payment on the Certificates will be
made, (ii) the amount of any such final payment in respect of each Class of
Certificates and (iii) that the Record Date otherwise applicable to such
Distribution Date is not applicable, payments being made only upon presentation
and surrender of the Certificates at the office or agency of the Trustee therein
designated. The Trustee shall give such notice to the other parties hereto at
the time such notice is given to Certificateholders.

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

            Section 9.02  Additional Termination Requirements

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

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

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

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

                                   ARTICLE X

                            ADDITIONAL TAX PROVISIONS

            Section 10.01 Tax Administration

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

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

            (c) [Reserved.]

            (d) The Holder of the largest Percentage Interest of the Class LR
Certificates is hereby designated, and by the acceptance of its Class LR
Certificate agrees to act, as Tax Matters Person for the Lower-Tier REMIC. The
Holder of the largest Percentage Interest of the Class R Certificates is hereby
designated, and by the acceptance of its Class R Certificate agrees to act, as
Tax Matters Person for the Upper-Tier REMIC. The Trustee is hereby designated as
the agent of the Tax Matters Person of the Lower-Tier REMIC and the Upper-Tier
REMIC and shall perform all the functions thereof, and the Holders of the Class
LR and Class R Certificates, by their acceptance of such Certificates, agree to
such designation.

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

            (f) The Trustee shall provide (i) upon request by any Transferor of
a Class LR or Class R Certificate, such information to such Transferor and the
IRS as is (x) reasonably necessary for the application of any tax relating to
the transfer of a Class LR or Class R Certificate to any Person who is a
Disqualified Organization or (y) otherwise required to be provided by Treasury
Regulations Section 1.860E-2 (and in the time and manner required to be provided
to such person under such Regulations), (ii) to the Certificateholders such
information or reports as are required by the Code, the REMIC Provisions or
State Tax Laws including reports relating to interest, original issue discount
and market discount or premium (using the Prepayment Assumption) and (iii) to
the Internal Revenue Service the name, title, address and telephone number of
the person who will serve as the representative of each of the Trust REMICs.

            (g) The Trustee shall take such actions and shall cause the Trust
Fund to take such actions as are reasonably within the Trustee's control and the
scope of its duties more specifically set forth herein as shall be necessary to
maintain the status of each Trust REMIC as a REMIC under the REMIC Provisions
(and the Master Servicers and Special Servicers shall assist the Trustee, to the
extent reasonably requested by the Trustee to do so). None of the Master
Servicers, the Special Servicers or the Trustee shall knowingly or intentionally
take any action, cause the Trust Fund to take any action or fail to take (or
fail to cause to be taken) any action reasonably within its control and the
scope of duties more specifically set forth herein, that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) cause either
Trust REMIC to fail to qualify as a REMIC or (ii) result in the imposition of a
tax under the REMIC Provisions upon either Trust REMIC (including but not
limited to the tax on prohibited transactions as defined in Section 860F(a)(2)
of the Code and the tax on contributions to a REMIC set forth in Section 860G(d)
of the Code) (either such event, an "Adverse REMIC Event") unless such party
receives an Opinion of Counsel (at the expense of the party seeking to take such
action or, if such party fails to pay such expense, and such party determines
that taking such action is in the best interest of the Trust Fund and the
Certificateholders, at the expense of the Trust Fund, but in no event at the
expense of such party) to the effect that the contemplated action will not, with
respect to either Trust REMIC, cause either Trust REMIC to fail to qualify as a
REMIC or, unless such party (which is acceptable to the Trustee) determines that
the monetary expense to either Trust REMIC is not material and in its sole
discretion to indemnify (to the extent reasonably acceptable to the Trustee) the
Trust Fund against such tax, result in the imposition of such a tax. Wherever in
this Agreement a contemplated action may not be taken because the taking of such
action might result in the imposition of a tax on the Trust Fund, or may be
taken only pursuant to an Opinion of Counsel that such action would impose a tax
on the Trust Fund, such action may nonetheless be taken so long as (x) the
indemnity given in the preceding sentence with respect to any taxes that might
be imposed on the Trust Fund has been given and (y) all other preconditions to
the taking of such action have been satisfied. The Trustee shall not take any
action (whether or not authorized hereunder) as to which a Master Servicer has
advised it in writing that it has received an Opinion of Counsel to the effect
that an Adverse REMIC Event could occur with respect to such action. In
addition, prior to taking any action with respect to the Trust Fund or its
assets, or causing the Trust Fund to take any action, which is not expressly
permitted under the terms of this Agreement, each of the parties hereto will
consult with the Trustee or its designee, in writing, with respect to whether
such action could cause an Adverse REMIC Event to occur with respect to either
Trust REMIC, and such party shall not take any such action, or cause either
Trust REMIC to take any such action, as to which the Trustee has advised it in
writing that an Adverse REMIC Event could occur. The Trustee may consult with
counsel to make such written advice, and the cost of same shall be borne by the
party seeking to take the action not expressly permitted by this Agreement. At
all times as may be required by the Code, the Trustee will, to the extent within
its control and the scope of its duties as specifically set forth herein,
maintain substantially all of the assets of the Trust Fund as "qualified
mortgages" as defined in Section 860G(a)(3) of the Code and "permitted
investments" as defined in Section 860G(a)(5) of the Code.

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

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

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

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

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

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

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

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

            (p) The Trustee shall be entitled to reasonable compensation and to
the reimbursement of its reasonable expenses incurred in the performance of its
duties under this Section 10.01 as may be agreed upon by the Trustee and the
Depositor; provided, however, that the Trustee shall pay out of its own funds,
without any right of reimbursement, any and all ordinary expenses of the Trust
Fund incurred in the performance of its duties under this Article but shall be
reimbursed, except as otherwise expressly provided for herein, by the Trust Fund
for any of its extraordinary expenses, including any taxes or tax-related
payments, any expenses involved in any tax examination, audit or proceeding, and
the expense of any tax-related Opinion of Counsel or other professional advice
requested by the Trustee for the benefit or protection of the
Certificateholders.

            Section 10.02  Depositor, Master Servicers, Special Servicers and
                           Fiscal Agent to Cooperate with Trustee

            (a) The Depositor shall provide or cause to be provided to the
Trustee, within 10 days after the Closing Date, all information or data that the
Trustee reasonably determines to be relevant for tax purposes as to the
valuations and issue prices of the Certificates, including the price, yield,
prepayment assumption and projected cash flow of the Certificates.

            (b) Each Master Servicer, each Special Servicer and any Fiscal Agent
shall furnish such reports, certifications and information in its possession,
and access to such books and records maintained thereby, as may relate to the
Certificates or the Trust Fund and as shall be reasonably requested by the
Trustee in order to enable it to perform its duties under this Article X.

                                   ARTICLE XI

                            MISCELLANEOUS PROVISIONS

            Section 11.01 Amendment

            (a) This Agreement may be amended from time to time by the mutual

Certificateholders or any B Loan Holder, (i) to cure any ambiguity, (ii) to
correct, modify or supplement any provision herein which may be inconsistent
with any other provision herein or to correct any error, (iii) to make any other

by an Opinion of Counsel delivered to the Trustee, the Master Servicers and the
Special Servicers, to relax or eliminate (A) any requirement hereunder imposed

that any such requirement may be relaxed or eliminated) or (B) any transfer
restriction imposed on the Certificates pursuant to Section 5.02(b) or Section
5.02(c) (if applicable law is amended or clarified such that any such

imposed by the Code or any successor or amendatory statute or any temporary or
final regulation, revenue ruling, revenue procedure or other written official
announcement or interpretation relating to federal income tax laws or any such
proposed action which, if made effective, would apply retroactively to either
Trust REMIC or the Grantor Trust at least from the effective date of such
amendment, or (Y) to avoid the occurrence of a prohibited transaction or to
reduce the incidence of any tax that would arise from any actions taken with
respect to the operation of either Trust REMIC or the Grantor Trust, (vi)

to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses and liabilities to be incurred therein

                  This certifies that [CEDE & CO.][NCB ENTITY] is the registered
owner of the Percentage Interest evidenced by this Certificate (obtained by
dividing the notional amount of this Certificate (its "Certificate Notional
Amount") as of the Closing Date by the aggregate notional amount of all the
Class [A-X] [A-SP] [A-Y] Certificates (their "Class Notional Amount") as of the
Closing Date) in that certain beneficial ownership interest in the Trust Fund
evidenced by all the Class [A-X] [A-SP] [A-Y] Certificates. The Trust Fund was
created and the Certificates were issued pursuant to a Pooling and Servicing
Agreement, dated as of March 1, 2003 (the "Agreement"), among Credit Suisse
First Boston Mortgage Securities Corp., as depositor (the "Depositor", which
term includes any successors in interest), Midland Loan Services, Inc., as
general master servicer (in such capacity, the "General Master Servicer," which
term includes any successors in interest), and general special servicer (in such
capacity, the "General Special Servicer", which term includes any successors in
interest), NCB, FSB, as co-op master servicer (in such capacity, the "Co-op
Master Servicer," which term includes any successors in interest), National
Consumer Cooperative Bank, as co-op special servicer (in such capacity, the
"Co-op Special Servicer," which term includes any successors in interest), 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 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 [A-X] [A-Y] [A-SP] 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
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  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 (other than in connection with the
initial issuance of the Certificates or a transfer of this Certificate by the
Depositor or any Affiliate of the Depositor) 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 Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust or of the Depositor, the General Master Servicer, the
General Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer,
the Trustee, any Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective Transferee on which such
Opinion of Counsel is based.

                  If this Certificate constitutes a Rule 144A Global Certificate
and a transfer of any interest in this Certificate is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Book-Entry Certificates or a transfer of any interest therein by
the Depositor, Credit Suisse First Boston LLC ("CSFB") or any of their
respective Affiliates), then 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 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. Any interest in a Rule
144A Global Certificate shall not be transferred to any Person who takes
delivery other than in the form of an interest in a Rule 144A Global
Certificate. Notwithstanding the preceding two sentences, any interest in a Rule
144A Global Certificate may be transferred (without delivery of any certificate
or Opinion of Counsel described in the second preceding sentence) by the
Depositor or any Affiliate of the Depositor to any Person who takes delivery in
the form of a beneficial interest in the Regulation S Global Certificate of the
same Class as the Rule 144A Global Certificate, as the case may be, upon
delivery to the Certificate Registrar of (x) 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 (y)
such written orders and instructions as are required under the applicable
procedures of DTC, Clearstream and Euroclear to direct the Trustee to debit the
account of a Depository Participant by a denomination of interests in the
related Rule 144A Global Certificate, and credit the account of a Depository
Participant by a denomination of interests in the related 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
certification and orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of DTC, shall reduce the denomination
of the related Rule 144A Global Certificate, and increase the denomination of
the related Regulation S Global Certificate, by the denomination of the
beneficial interest in such Class specified in such orders and instructions.

                  If this Certificate constitutes a Regulation S Global
Certificate, then beneficial interests in this Certificate shall not be
transferred to any Person who takes delivery other than in the form of a
beneficial interest in this Certificate, and the Certificate Owner desiring to
effect such transfer shall be required to obtain from such Certificate Owner's
prospective Transferee a Regulation S Certificate. 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.

                  The Rule 144A Global Certificates and the Regulation S Global
Certificates shall be deposited with the Trustee as custodian for DTC and
registered in the name of Cede & Co. as nominee of DTC. [Remove for A-Y]

Registrar is obligated to register or qualify the Class [A-X] [A-Y] [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, the Depositor, the Trustee, the General Master Servicer, the General
Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer, any
Fiscal Agent 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 four preceding paragraphs.

                  No transfer of this Certificate or any interest herein shall

accounts or arrangements are invested, including insurance company general
accounts, that is subject to ERISA or Section 4975 of the Code or any
essentially similar provision of applicable federal, state or local law
("Similar Law") (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 Similar Law or would result in the imposition of an excise
tax under Section 4975 of the Code or Similar Law. 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 similar exemption under Similar Law); 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 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, any Fiscal Agent,
any Mortgage Loan Seller, any Exemption-Favored Party, the General Master
Servicer, the General Special Servicer, the Co-op Master Servicer, the Co-op
Special Servicer, any Sub-Servicer or any Borrower with respect to Mortgage
Loans constituting 5% of the aggregate unamortized principal of all the Mortgage
Loans determined as of the Closing Date, or by 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 Certificate Registrar (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 Similar Law or result in the imposition of an excise tax under
Section 4975 of the Code or Similar Law. It is hereby acknowledged that the
forms of certification attached to the Agreement as Exhibit G-1 (in the case of
Definitive Certificates), and Exhibit G-2 (in the case of ownership interests in
Book-Entry Certificates) are acceptable for purposes of the preceding sentence.

                  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 as 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

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
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in the
Trust Fund, (ii) the purchase by any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, the Co-op Master Servicer, the
Co-op Special Servicer, the General Master Servicer or the General Special
Servicer, in that order of preference, at a price determined as provided in the
Agreement, of all the Mortgage Loans and each REO Property remaining in the
Trust Fund and (iii) the acquisition by the Sole Certificateholder(s) of all the
Mortgage Loans and each REO Property remaining in the Trust Fund in exchange for
all of the Certificates. The Agreement permits, but does not require, the
General Master Servicer, the General Special Servicer, the Co-op Master
Servicer, the Co-op 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

Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent with the consent of the Holders of Certificates entitled to not
less than 51% of the Voting Rights allocated to all of the Classes materially
affected by the amendment. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of the Upper-Tier REMIC and the Lower-Tier REMIC 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.

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

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

the Code or Similar Law or result in the imposition of an excise tax under
Section 4975 of the Code or Similar Law. It is hereby acknowledged that the
forms of certification attached to the Agreement as Exhibit G-1 (in the case of
Definitive Certificates), and Exhibit G-2 (in the case of ownership interests in

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

power to make the acknowledgments, representations, warranties, certifications
and/or agreements with respect to each such account as described above in this
Certificate.

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

Trustee, any Fiscal Agent, the Certificate Registrar and any agent of the

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

                  Subject to certain terms and conditions set forth in the
Agreement, the Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in the
Trust Fund, (ii) the purchase by any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, the Co-op Master Servicer, the
Co-op Special Servicer, the General Master Servicer or the General Special

Agreement, of all the Mortgage Loans and each REO Property remaining in the
Trust Fund and (iii) the acquisition by the Sole Certificateholder(s) of all the
Mortgage Loans and each REO Property remaining in the Trust Fund in exchange for
all of the Certificates. The Agreement permits, but does not require, any single
Controlling Class Certificateholder or group of Controlling Class
Certificateholders, the Co-op Master Servicer, the Co-op Special Servicer, the
General Master Servicer or the General Special Servicer 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 General Master Servicer, the General Special

any Fiscal Agent and the rights of the Certificateholders under the Agreement at
any time by the Depositor, the General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent with the consent of the Holders of Certificates entitled to not
less than 51% of the Voting Rights allocated to all of the Classes materially
affected by the amendment. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of the Upper-Tier REMIC or the Lower-Tier REMIC 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.

THIS CERTIFICATE IS SUBORDINATE TO ONE OR MORE CLASSES OF CERTIFICATES OF THE
SAME SERIES AS AND TO THE EXTENT DESCRIBED IN THE POOLING AND SERVICING
AGREEMENT REFERRED TO HEREIN.

SOLELY FOR U.S. FEDERAL INCOME TAX PURPOSES, THIS CERTIFICATE IS A "REGULAR
INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE CODE.

THE OUTSTANDING CERTIFICATE PRINCIPAL BALANCE HEREOF AT ANY TIME MAY BE LESS
THAN THE AMOUNT SHOWN ABOVE.

                  This certifies that [CEDE & CO.] is the registered owner of
the Percentage Interest evidenced by this Certificate (obtained by dividing the
principal amount of this Certificate (its "Certificate Principal Balance") as of
the Closing Date by the aggregate principal amount of all the Class [F] [G] [H]
Certificates (their "Class Principal Balance") as of the Closing Date) in that
certain beneficial ownership interest in the Trust Fund evidenced by all the
Class [F] [G] [H] Certificates. The Trust Fund was created and the Certificates
were issued pursuant to a Pooling and Servicing Agreement, dated as of March 1,
2003 (the "Agreement"), among Credit Suisse First Boston Mortgage Securities
Corp., as depositor (the "Depositor", which term includes successors in
interest), Midland Loan Services, Inc., as general master servicer (in such
capacity, the "General Master Servicer," which term includes any successors in
interest), and general special servicer (in such capacity, the "General Special
Servicer", which term includes any successors in interest), NCB, FSB, as co-op
master servicer (in such capacity, the "Co-op Master Servicer," which term
includes any successors in interest), National Consumer Cooperative Bank, as
co-op special servicer (in such capacity, the "Co-op Special Servicer," which
term includes any successors in interest), 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 [F] [G] [H] 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
(determined without regard to any possible future reimbursement of any portion
of a Collateral Support Deficit in respect of 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
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

                  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 (other than in connection with the
initial issuance of the Certificates or a transfer of this Certificate by the
Depositor or any Affiliate of the Depositor) 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 Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust or of the Depositor, the General Master Servicer, the
General Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer,
the Trustee, any Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective Transferee on which such
Opinion of Counsel is based.

                  If this Certificate constitutes a Rule 144A Global Certificate
and a transfer of any interest in this Certificate is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Book-Entry Certificates or a transfer of any interest therein by
the Depositor, Credit Suisse First Boston LLC ("CSFB") or any of their
respective Affiliates), then 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 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. Any interest in a Rule
144A Global Certificate shall not be transferred to any Person who takes
delivery other than in the form of an interest in a Rule 144A Global
Certificate. Notwithstanding the preceding two sentences, any interest in a Rule
144A Global Certificate may be transferred (without delivery of any certificate
or Opinion of Counsel described in the second preceding sentence) by the
Depositor or any Affiliate of the Depositor to any Person who takes delivery in
the form of a beneficial interest in the Regulation S Global Certificate of the
same Class as the Rule 144A Global Certificate, as the case may be, upon
delivery to the Certificate Registrar of (x) 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 (y)
such written orders and instructions as are required under the applicable
procedures of DTC, Clearstream and Euroclear to direct the Trustee to debit the
account of a Depository Participant by a denomination of interests in the
related Rule 144A Global Certificate, and credit the account of a Depository
Participant by a denomination of interests in the related 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
certification and orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of DTC, shall reduce the denomination
of the related Rule 144A Global Certificate, and increase the denomination of
the related Regulation S Global Certificate, by the denomination of the
beneficial interest in such Class specified in such orders and instructions.

                  If this Certificate constitutes a Regulation S Global
Certificate, then beneficial interests in this Certificate shall not be
transferred to any Person who takes delivery other than in the form of a
beneficial interest in this Certificate, and the Certificate Owner desiring to
effect such transfer shall be required to obtain from such Certificate Owner's
prospective Transferee a Regulation S Certificate. 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.

                  The Rule 144A Global Certificates and the Regulation S 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] 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, the Trustee the General Master Servicer, the General
Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer, any
Fiscal Agent 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 four 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 or any
essentially similar provision of applicable federal, state or local law
("Similar Law") (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 Similar Law or would result in the imposition of an excise
tax under Section 4975 of the Code or Similar Law. 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 similar exemption under Similar Law); 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 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, any Fiscal Agent,
any Mortgage Loan Seller, any Exemption-Favored Party, the General Master
Servicer, the General Special Servicer, the Co-op Master Servicer, the Co-op
Special Servicer, any Sub-Servicer or any Borrower with respect to Mortgage
Loans constituting 5% of the aggregate unamortized principal of all the Mortgage
Loans determined as of the Closing Date, or by 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 Certificate Registrar (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 Similar Law or result in the imposition of an excise tax under
Section 4975 of the Code or Similar Law. It is hereby acknowledged that the
forms of certification attached to the Agreement as Exhibit G-1 (in the case of
Definitive Certificates), and Exhibit G-2 (in the case of ownership interests in
Book-Entry Certificates) are acceptable for purposes of the preceding sentence.

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

                  Subject to certain terms and conditions set forth in the
Agreement, the Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in the
Trust Fund, (ii) the purchase by any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, the Co-op Master Servicer, the
Co-op Special Servicer, the General Master Servicer or the General Special
Servicer, in that order of preference, at a price determined as provided in the
Agreement, of all the Mortgage Loans and each REO Property remaining in the
Trust Fund and (iii) the acquisition by the Sole Certificateholder(s) of all the
Mortgage Loans and each REO Property remaining in the Trust Fund in exchange for
all of the Certificates. The Agreement permits, but does not require, the
General Master Servicer, the General Special Servicer, the Co-op Master
Servicer, the Co-op 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 General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent and the rights of the Certificateholders under the Agreement at
any time by the Depositor, the General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent with the consent of the Holders of Certificates entitled to not
less than 51% of the Voting Rights allocated to all of the Classes materially
affected by the amendment. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of the Upper-Tier REMIC or the Lower-Tier REMIC 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.

INTEREST" IN A "REAL ESTATE MORTGAGE INVESTMENT CONDUIT" (A "REMIC") AS THOSE
TERMS ARE DEFINED, RESPECTIVELY, IN SECTIONS 860G AND 860D OF THE CODE.

THE OUTSTANDING CERTIFICATE PRINCIPAL BALANCE HEREOF AT ANY TIME MAY BE LESS
THAN THE AMOUNT SHOWN ABOVE.

                  This certifies that [CEDE & CO.] is the registered owner of
the Percentage Interest evidenced by this Certificate (obtained by dividing the
principal amount of this Certificate (its "Certificate Principal Balance") as of
the Closing Date by the aggregate principal amount of all the Class [J] [K] [L]
[M] [N] [O] [P] [Q] Certificates (their "Class Principal Balance") as of the
Closing Date) in that certain beneficial ownership interest in the Trust Fund

Trust Fund was created and the Certificates were issued pursuant to a Pooling
and Servicing Agreement, dated as of March 1, 2003 (the "Agreement"), among
Credit Suisse First Boston Mortgage Securities Corp., as depositor (the
"Depositor", which term includes successors in interest), Midland Loan Services,

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 [J] [K] [L] [M] [N] [O] [P] [Q] 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 (determined without regard to any possible future reimbursement
of any portion of an Collateral Support Deficit in respect of 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
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

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

                  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.

                  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 (other than in connection with the
initial issuance of the Certificates or a transfer of this Certificate by the
Depositor or any Affiliate of the Depositor) 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 Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust or of the Depositor, the General Master Servicer, the
General Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer,
the Trustee, any Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective Transferee on which such
Opinion of Counsel is based.

                  If this Certificate constitutes a Rule 144A Global Certificate
and a transfer of any interest in this Certificate is to be made without
registration under the Securities Act (other than in connection with the initial
issuance of the Book-Entry Certificates or a transfer of any interest therein by
the Depositor, Credit Suisse First Boston LLC ("CSFB") or any of their
respective Affiliates), then 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 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. Any interest in a Rule
144A Global Certificate shall not be transferred to any Person who takes
delivery other than in the form of an interest in a Rule 144A Global
Certificate. Notwithstanding the preceding two sentences, any interest in a Rule
144A Global Certificate may be transferred (without delivery of any certificate
or Opinion of Counsel described in the second preceding sentence) by the
Depositor or any Affiliate of the Depositor to any Person who takes delivery in
the form of a beneficial interest in the Regulation S Global Certificate of the
same Class as the Rule 144A Global Certificate, as the case may be, upon
delivery to the Certificate Registrar of (x) 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 (y)
such written orders and instructions as are required under the applicable
procedures of DTC, Clearstream and Euroclear to direct the Trustee to debit the
account of a Depository Participant by a denomination of interests in the
related Rule 144A Global Certificate, and credit the account of a Depository
Participant by a denomination of interests in the related 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
certification and orders and instructions, the Trustee, subject to and in
accordance with the applicable procedures of DTC, shall reduce the denomination
of the related Rule 144A Global Certificate, and increase the denomination of
the related Regulation S Global Certificate, by the denomination of the
beneficial interest in such Class specified in such orders and instructions.

                  If this Certificate constitutes a Regulation S Global
Certificate, then beneficial interests in this Certificate shall not be
transferred to any Person who takes delivery other than in the form of a
beneficial interest in this Certificate, and the Certificate Owner desiring to
effect such transfer shall be required to obtain from such Certificate Owner's
prospective Transferee a Regulation S Certificate. 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.

                  The Rule 144A Global Certificates and the Regulation S 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 [J] [K] [L] [M] [N] [O]
[P] [Q] 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, 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 General Master Servicer,
the General Special Servicer, the Co-op Master Servicer, the Co-op Special
Servicer and the Certificate Registrar against any liability that may result if
such transfer, sale, pledge or other disposition is not exempt from the
registration and/or qualification requirements of the Securities Act and any
applicable state securities laws or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate or any interest herein shall
be made (A) to any retirement plan or other employee benefit plan or
arrangement, including individual retirement accounts and annuities, Keogh plans
and collective investment funds and separate accounts in which such plans,
accounts or arrangements are invested, including insurance company general
accounts, that is subject to ERISA or Section 4975 of the Code or any
essentially similar provision of applicable federal, state or local law
("Similar Law") (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 Similar Law or would result in the imposition of an excise
tax under Section 4975 of the Code or Similar Law. 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 similar exemption under Similar Law); 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 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, any Fiscal Agent,
any Mortgage Loan Seller, any Exemption-Favored Party, the General Master
Servicer, the General Special Servicer, the Co-op Master Servicer, the Co-op
Special Servicer, any Sub-Servicer or any Borrower with respect to Mortgage
Loans constituting 5% of the aggregate unamortized principal of all the Mortgage
Loans determined as of the Closing Date, or by 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 Certificate Registrar (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 Similar Law or result in the imposition of an excise tax under
Section 4975 of the Code or Similar Law. It is hereby acknowledged that the
forms of certification attached to the Agreement as Exhibit G-1 (in the case of
Definitive Certificates), and Exhibit G-2 (in the case of ownership interests in
Book-Entry Certificates) are acceptable for purposes of the preceding sentence.

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

                  Subject to certain terms and conditions set forth in the
Agreement, the Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in the
Trust Fund, (ii) the purchase by any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, the Co-op Master Servicer, the
Co-op Special Servicer, the General Master Servicer or the General Special
Servicer, in that order of preference, at a price determined as provided in the
Agreement, of all the Mortgage Loans and each REO Property remaining in the
Trust Fund and (iii) the acquisition by the Sole Certificateholder(s) of all the
Mortgage Loans and each REO Property remaining in the Trust Fund in exchange for
all of the Certificates. The Agreement permits, but does not require, the
General Master Servicer, the General Special Servicer, the Co-op Master
Servicer, the Co-op 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 General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent and the rights of the Certificateholders under the Agreement at
any time by the Depositor, the General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent with the consent of the Holders of Certificates entitled to not
less than 51% of the Voting Rights allocated to all of the Classes materially
affected by the amendment. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of the Upper-Tier REMIC or the Lower-Tier REMIC 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.

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

Class V 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

Agreement, withdrawals from the Distribution Account, the Collection Account
and, if established, the REO Account may be made from time to time for purposes

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

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

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

Depositor or any Affiliate of the Depositor) 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 Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust or of the Depositor, the General Master Servicer, the
General Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer,
the Trustee, any Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective Transferee on which such
Opinion of Counsel is based. Any Certificateholder desiring to effect a
transfer, sale, pledge or other disposition of this Certificate or any interest
herein shall, and does hereby agree to, indemnify the Depositor, Credit Suisse
First Boston LLC, the Trustee, any Fiscal Agent, the General Master Servicer,
the General Special Servicer, the Co-op Master Servicer, the Co-op Special
Servicer, and the Certificate Registrar against any liability that may result if
such transfer, sale, pledge or other disposition is not exempt from the
registration and/or qualification requirements of the Securities Act and any
applicable state securities laws or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate or any interest herein shall
be made except to a Qualified Institutional Buyer or an Institutional Accredited
Investor. The Certificate Registrar shall refuse to register the transfer of
this Certificate unless it has received from the prospective Transferee a
certification to the effect that such prospective Transferee is a Qualified
Institutional Buyer or an Institutional Accredited Investor.

                  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 or any
essentially similar provision of applicable federal, state or local law("Similar
Law") (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. The Certificate Registrar
shall refuse to register the transfer of this Certificate unless it has received
from the prospective Transferee 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. It is hereby acknowledged that the form of
certification attached to the Agreement as Exhibit G-1 is acceptable for
purposes of the preceding sentence.

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

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

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

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

                  Subject to certain terms and conditions set forth in the
Agreement, the Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in the
Trust Fund, (ii) the purchase by any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, the Co-op Master Servicer, the
Co-op Special Servicer, the General Master Servicer or the General Special
Servicer, in that order of preference, at a price determined as provided in the
Agreement, of all the Mortgage Loans and each REO Property remaining in the
Trust Fund and (iii) the acquisition by the Sole Certificateholder(s) of all the
Mortgage Loans and each REO Property remaining in the Trust Fund in exchange for
all of the Certificates. The Agreement permits, but does not require, the
General Master Servicer, the General Special Servicer, the Co-op Master
Servicer, the Co-op 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 General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent and the rights of the Certificateholders under the Agreement at
any time by the Depositor, the 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. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future Holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon this Certificate. The Agreement also permits the
amendment thereof, in certain limited circumstances, including any amendment
necessary to maintain the status of the Upper-Tier REMIC or the Lower-Tier REMIC
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.

                  This certifies that Credit Suisse First Boston LLC is the
registered owner of the Percentage Interest evidenced by this Certificate (as
specified above) in that certain beneficial ownership interest in the Trust Fund
evidenced by all the Class [R] [LR] Certificates. The Trust Fund was created and
the Certificates were issued pursuant to a Pooling and Servicing Agreement,
dated as of March 1, 2003 (the "Agreement"), among Credit Suisse First Boston
Mortgage Securities Corp., as depositor (the "Depositor", which term includes
successors in interest), Midland Loan Services, Inc., as general master servicer
(in such capacity, the "General Master Servicer," which term includes any
successors in interest), and general special servicer (in such capacity, the
"General Special Servicer", which term includes any successors in interest),
NCB, FSB, as co-op master servicer (in such capacity, the "Co-op Master
Servicer," which term includes any successors in interest), National Consumer
Cooperative Bank, as co-op special servicer (in such capacity, the "Co-op
Special Servicer," which term includes any successors in interest), and Wells
Fargo Bank Minnesota, N.A. as trustee (the "Trustee", which term includes any
successors in interest), 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] [LR] 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

specifically set forth herein and in the Agreement. As provided in the
Agreement, withdrawals from the Distribution Account, the Collection Account
and, if established, the REO Account may be made from time to time for purposes
other than, and, in certain cases, prior to, distributions to
Certificateholders, such purposes including the reimbursement of advances made,
or certain expenses incurred, with respect to the Mortgage Loans and the payment
of interest on such advances and expenses.

                  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 (other than in connection with the
initial issuance of the Certificates or a transfer of this Certificate by the
Depositor or any Affiliate of the Depositor) 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 Certificate Registrar to the effect that such transfer may be made without
registration under the Securities Act (which Opinion of Counsel shall not be an
expense of the Trust or of the Depositor, the General Master Servicer, the
General Special Servicer, the Co-op Master Servicer, the Co-op Special Servicer,
the Trustee, any Fiscal Agent or the Certificate Registrar in their respective
capacities as such), together with the written certification(s) as to the facts
surrounding such transfer from the Certificateholder desiring to effect such
transfer and/or such Certificateholder's prospective Transferee on which such
Opinion of Counsel is based. Any Certificateholder desiring to effect a
transfer, sale, pledge or other disposition of this Certificate or any interest
herein shall, and does hereby agree to, indemnify the Depositor, Credit Suisse
First Boston LLC, the Trustee, any Fiscal Agent, the General Master Servicer,
the General Special Servicer, the Co-op Master Servicer, the Co-op Special
Servicer, and the Certificate Registrar against any liability that may result if
such transfer, sale, pledge or other disposition is not exempt from the
registration and/or qualification requirements of the Securities Act and any
applicable state securities laws or is not made in accordance with such federal
and state laws.

                  No transfer of this Certificate or any interest herein shall
be made except to a Qualified Institutional Buyer. The Certificate Registrar
shall refuse to register the transfer of this Certificate unless it has received
from the prospective Transferee a certification to the effect that such
prospective Transferee is a Qualified Institutional Buyer.

                  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 or any
essentially similar provision of applicable federal, state or local law
("Similar Law") (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. The Certificate
Registrar shall refuse to register the transfer of this Certificate unless it
has received from the prospective Transferee 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. It is hereby acknowledged that the form of
Certification attached to the Agreement as Exhibit G-1 is acceptable for
purposes of the preceding sentence.

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

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

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

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

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

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

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

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

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

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

                  Subject to certain terms and conditions set forth in the
Agreement, the Trust Fund and the obligations created by the Agreement shall
terminate upon distribution (or provision for distribution) to the
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be distributed to them pursuant to the Agreement following the
earlier of (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Mortgage Loan or REO Property remaining in the
Trust Fund, (ii) the purchase by any single Controlling Class Certificateholder
or group of Controlling Class Certificateholders, the Co-op Master Servicer, the
Co-op Special Servicer, the General Master Servicer or the General Special
Servicer, in that order of preference, at a price determined as provided in the
Agreement, of all the Mortgage Loans and each REO Property remaining in the
Trust Fund and (iii) the acquisition by the Sole Certificateholder(s) of all the
Mortgage Loans and each REO Property remaining in the Trust Fund in exchange for
all of the Certificates. The Agreement permits, but does not require, the
General Master Servicer, the General Special Servicer, the Co-op Master
Servicer, the Co-op 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 General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent and the rights of the Certificateholders under the Agreement at
any time by the Depositor, the General Master Servicer, the General Special
Servicer, the Co-op Master Servicer, the Co-op Special Servicer, the Trustee and
any Fiscal Agent with the consent of the Holders of Certificates entitled to not
less than 51% of the Voting Rights allocated to all of the Classes materially
affected by the amendment. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future Holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon this Certificate. The Agreement also permits the amendment thereof, in
certain limited circumstances, including any amendment necessary to maintain the
status of any Trust REMIC 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.

Ladies and Gentlemen:

                  Pursuant to Section 2.02(b) of the Pooling and Servicing
Agreement dated as of March 1, 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 Mortgage Loan subject to the
Agreement (except as to any LOC Cash Reserve and 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 such report is due 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); and (iii) all documents received by it or any
Custodian with respect to such Mortgage Loan have been reviewed by it or by such
Custodian on its behalf accurately reflects the information set forth in the
related Mortgage File and (A) appear regular on their face (handwritten
additions, changes or corrections shall not constitute irregularities if
initialed by the Borrower), (B) appear to have been executed and (C) purport to
relate to such Mortgage Loan.

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

                  In performing the reviews contemplated by Sections 2.02(a),
and 2.02(b) of the Agreement, the Trustee may conclusively rely on the purported
genuineness of any such document and any signature thereon. It is understood
that the scope of the Trustee's review of the Mortgage Files is limited solely
to confirming that the documents specified in clauses (i), through (v), in
clause (vii), and, in the case of any 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 assume for purposes of the certifications delivered pursuant to Section
2.02 of the Agreement, that one State level UCC filing and one county level UCC
filing was made for each property.

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


                                           Respectfully,

                              [Issue description (the "Securities")]


Ladies and Gentlemen:

     This letter sets forth our understanding with respect to certain matters
relating to the Securities. Agent shall act as trustee, paying agent, fiscal
agent, or other such agent of Issuer with respect to the Securities. The
Securities have been issued pursuant to a trust indenture, trust agreement,
pooling and servicing agreement or other such document authorizing the issuance
of the Securities dated March 13, 2003 (the "Document").

Credit Suisse First Boston LLC, PNC Capital Markets, Inc., J.P. Morgan
Securities Inc., and Greenwich Capital Markets, Inc. ["Underwriter/Placement
Agent"] is distributing the Securities through The Depository Trust Company
("DTC").

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

         1. Prior to closing on the Securities on March 13, 2003 there shall be
deposited with DTC one or more Security certificates registered in the name of
DTC's nominee, Cede & Co., for each Class of the Securities in the face amounts
set forth on Schedule A hereto, the total of which represents 100% of the
principal amount of such Securities. If, however, the aggregate principal amount
of any maturity exceeds $400 million, one certificate shall be issued with
respect to each $400 million of principal amount and an additional certificate
shall be issued with respect to any remaining principal amount. Each Security
certificate shall bear the following legend:

               Unless this certificate is presented by an
          authorized representative of The Depository Trust
          Company, a New York corporation ("DTC"), to Issuer or
          its agent for registration of transfer, exchange, or
          payment, and any certificate issued is registered in
          the name of Cede & Co. or in such other name as is
          requested by an authorized representative of DTC (and
          any payment is made to Cede & Co. or to such other
          entity as is requested by an authorized representative
          of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR
          VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
          inasmuch as the registered owner hereof, Cede & Co.,
          has an interest herein.

Issuer represents: [NOTE: ISSUER MUST REPRESENT ONE OF THE FOLLOWING, AND
SHALL CROSS OUT THE OTHER.]

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

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

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

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

         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
to:

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

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

                           Manager, Reorganization Department
                           Reorganization Window
                           The Depository Trust Company
                           55 Water Street 50th Floor
                           New York, NY  10041-0099

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

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

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

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

         8. Issuer or Agent shall send DTC written notice with respect to the
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
                           Dividend Department
                           The Depository Trust Company
                           55 Water Street 25th Floor
                           New York, NY 10041-0099

         9. Issuer represents: [NOTE: ISSUER MUST REPRESENT ONE OF THE
FOLLOWING, AND SHALL CROSS OUT THE OTHER.] [The interest accrual period is
the calendar month preceding the month in which a distribution date (which is
the fourth business day following the eleventh calendar day of any month, or
if such eleventh calendar day is not a business day, then the next succeeding
business day) occurs.  Each Interest Accrual Period shall be deemed for
purposes of this definition to consist of 30 days.

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

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

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

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

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

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

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

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

         18. In the event that Issuer determines that beneficial owners of
Securities shall be able to obtain certificated Securities, Issuer or Agent
shall notify DTC of the availability of certificates. In such event, Issuer or
Agent shall issue, transfer, and exchange certificates in appropriate amounts,
as required by DTC and others. All duties of the Trustee and the Depositor under
this Letter of Representations with respect to the Securities shall terminate in
the event that no Securities remain outstanding or all the Securities are
transferred to a Person that is not DTC or a nominee of DTC. All obligations
hereunder of the Issuer will be performed by Credit Suisse First Boston Mortgage
Securities Corp., as Depositor, or the Depositor will cause the Issuer to
perform such obligations.

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

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

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

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

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

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

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

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

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

         28. The Depositor and the Trustee acknowledge that DTC is not a party
to the Document and that no obligations or liabilities shall be deemed to accrue
to DTC with regard to the Document.

         29. Capitalized terms used and not otherwise defined herein shall have
the respective meanings given to such terms in the Document.

         30. The parties agree that, without prejudice to the rights of the
parties to take any proceedings in relation hereto before any other court of
competent jurisdiction, the courts of the State of New York shall have
jurisdiction to hear and determine any suit, action or proceeding and to settle
any disputes, which may arise out of or in connection with this Letter of
Representations, and, for such purposes, each irrevocably submits to the
non-exclusive jurisdiction of such courts.

                  SAMPLE OFFERING DOCUMENT LANGUAGE DESCRIBING
                            BOOK-ENTRY-ONLY ISSUANCE
                  --------------------------------------------
 (Prepared by DTC--bracketed material may be applicable only to certain issues)

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

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

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

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

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

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

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

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

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

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

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

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

                   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.]

PORTAL and Investment Grade classes described on following page.

[An issue of nonconvertible debt securities or nonconvertible preferred stock
which is rated in one of the top four categories by a nationally recognized
statistical rating organization ("Investment Grade Securities").]

[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.


-------------------------
      [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."

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.

        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 April 22, 2003 [, 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:

                             [Issue description (the "Securities")]
Ladies and Gentlemen:

      This letter sets forth our understanding with respect to certain matters
relating to the Securities. Agent shall act as trustee, paying agent, fiscal
agent, or other such agent of Issuer with respect to the Securities. The
Securities have been issued pursuant to a trust indenture, trust agreement,
pooling and servicing agreement or other such document authorizing the issuance
of the Securities dated March 13, 2003 (the "Document"). Credit Suisse First
Boston LLC, PNC Capital Markets, Inc., J.P. Morgan Securities Inc., and
Greenwich Capital Markets, Inc. is distributing the Securities through The
Depository Trust Company ("DTC").  ["Underwriter/Placement Agent"]

      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 March 13, 2003 there shall be
deposited with DTC one or more Security certificates registered in the name of
DTC's nominee, Cede & Co., for each Class of the Securities in the
face amounts set forth on Schedule A hereto, the total of which represents 100%
of the principal amount of such Securities. If, however, the aggregate principal
amount of any maturity exceeds $400 million, one certificate shall be issued
with respect to each $400 million of principal amount and an additional
certificate shall be issued with respect to any remaining principal amount. Each
Security certificate shall bear the following legend:

            Unless this certificate is presented by an authorized representative
      of The Depository Trust Company, a New York corporation ("DTC"), to Issuer
      or its agent for registration of transfer, exchange, or payment, and any
      certificate issued is registered in the name of Cede & Co. or in such
      other name as is requested by an authorized representative of DTC (and any
      payment is made to Cede & Co. or to such other entity as is requested by
      an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
      HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as
      the registered owner hereof, Cede & Co., has an interest herein.

Issuer represents: [NOTE: ISSUER MUST REPRESENT ONE OF THE FOLLOWING, AND SHALL
CROSS OUT THE OTHER.]

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

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

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

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

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

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

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

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

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

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

                           Manager, Reorganization Department
                           Reorganization Window

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

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

                           Supervisor, Put Bond Unit
                           Reorganization Department

                           New York, NY 10041-0099

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

      8. Issuer or Agent shall send DTC written notice with respect to the
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
                           Dividend Department
                           The Depository Trust Company
                           55 Water Street 25th Floor
                           New York, NY 10041-0099

      9. Issuer represents: [NOTE: ISSUER MUST REPRESENT ONE OF THE FOLLOWING,
AND SHALL CROSS OUT THE OTHER.] [THE interest accrual period is the calendar
month preceding the month in which a distribution date (which is the fourth
business day following the eleventh calendar day of any month, or if such
eleventh calendar day is not a business day, then the next succeeding business
day) occurs. Each Interest Accrual Period shall be deemed for purposes of this
definition to consist of 30 days.]

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

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

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

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

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

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

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

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

      18. In the event that Issuer determines that beneficial owners of
Securities shall be able to obtain certificated Securities, Issuer or Agent
shall notify DTC of the availability of certificates. In such event, Issuer or
Agent shall issue, transfer, and exchange certificates in appropriate amounts,
as required by DTC and others. All duties of the Trustee and the Depositor under
this Letter of Representations with respect to the Securities shall terminate in
the event that no Securities remain outstanding or all the Securities are
transferred to a Person that is not DTC or a nominee of DTC. All obligations
hereunder of the Issuer will be performed by Credit Suisse First Boston Mortgage
Securities Corp., as Depositor, or the Depositor will cause the Issuer to
perform such obligations.

      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 Rider 5 Issuer.

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

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

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

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

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

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

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

      28. The Depositor and the Trustee acknowledge that DTC is not a party to
the Document and that no obligations or liabilities shall be deemed to accrue to
DTC with regard to the Document.

      29. Capitalized terms used and not otherwise defined herein shall have the
respective meanings given to such terms in the Document.

      30. The parties agree that, without prejudice to the rights of the parties
to take any proceedings in relation hereto before any other court of competent
jurisdiction, the courts of the State of New York shall have jurisdiction to
hear and determine any suit, action or proceeding and to settle any disputes,
which may arise out of or in connection with this Letter of Representations,
and, for such purposes, each irrevocably submits to the non-exclusive
jurisdiction of such courts.

                                                                      SCHEDULE B

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

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

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

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

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

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

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

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

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

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

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

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

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

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

       Form of CMSA Servicer Watch List Criteria for Co-op Mortgage Loans

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

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

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

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

(v)      A loan that is at least 60 days delinquent in payment (without regard
         to any grace period);

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

(vii)    A loan that is within 60 days of maturity;

(viii)   A loan as to which the Co-op Master Servicer has determined, consistent
         with the Servicing Standard, that a payment default is reasonably
         likely to occur because the annual maintenance on the related property
         is more than 5% in arrears, such arrearage has continued for four or
         more months and the related borrower has less than 10% of the annual
         maintenance in reserve;

(ix)     A loan as to which any material litigation exists involving the
         Borrower or the related Mortgaged Property;

(x)      A loan as to which a lien, in excess of 5% of the unpaid principal
         balance of the related loan, has been filed against the related
         Mortgaged Property; and

(xi)     A loan as to which any material deferred maintenance is identified by
         the Co-op Master Servicer at the related property and such deferred
         maintenance is not cured within 120 days of the identification thereof.


For purposes of item "(i)" above, debt service coverage ratio shall mean, as of
the date of any determination, the net operating income for the trailing 12
month period for the related property (based on actual receipt of maintenance
payments from tenant-shareholders less actual operating expenses for the related
period, all as set forth in the most recent annual financial statement submitted
by the borrower) divided by the actual aggregate mortgage payments for such
period.

Dear Sirs:

                  This letter is delivered to you in connection with the
transfer by _________________ (the "Transferor") to _________________ (the
"Transferee") of the captioned Certificates (the "Transferred Certificates")
pursuant to Section 5.02 of the Pooling and Servicing Agreement (the "Pooling
and Servicing Agreement"), dated as of March 1, 2003 among Credit Suisse First
Boston Mortgage Securities Corp., as depositor, Midland Loan Services, Inc., as
general master servicer (the "General Master Servicer"), and general special
servicer (the "General Special Servicer"), NCB, FSB, as co-op master servicer
(the "Co-op Master Servicer"), National Consumer Cooperative Bank, as co-op
special servicer (the "Co-op Special Servicer"), and Wells Fargo Bank Minnesota,
N.A. as Trustee (the "Trustee"). All capitalized terms used herein and not
otherwise defined shall have the respective meanings set forth in the Pooling
and Servicing Agreement. The Transferor hereby certifies, represents and
warrants to you, as Certificate Registrar, that:

                  1.      The Transferor is the lawful owner of the Transferred
Certificates with the full right to transfer such Certificates free from any and
all claims and encumbrances whatsoever.

                  2.      Neither the Transferor nor anyone acting on its
behalf has (a) offered, transferred, pledged, sold or otherwise disposed of any
Transferred Certificate, any interest in a Transferred Certificate or any other
similar security to any person in any manner, (b) solicited any offer to buy or
accept a transfer, pledge or other disposition of any Transferred Certificate,
any interest in a Transferred Certificate or any other similar security from any
person in any manner, (c) otherwise approached or negotiated with respect to any
Transferred Certificate, any interest in a Transferred Certificate or any other
similar security with any person in any manner, (d) made any general
solicitation with respect to any Transferred Certificate, any interest in a
Transferred Certificate or any other similar security by means of general
advertising or in any other manner, or (e) taken any other action with respect
to any Transferred Certificate, any interest in a Transferred Certificate or any
other similar security, which (in the case of any of the acts described in
clauses (a) through (e) hereof) would constitute a distribution of the
Transferred Certificates under the Securities Act of 1933, as amended (the
"Securities Act"), or would render the disposition of the Transferred
Certificates a violation of Section 5 of the Securities Act or any state
securities laws, or would require registration or qualification of the
Transferred Certificates pursuant to the Securities Act or any state securities
laws.

                  3.      The Transferor and any person acting on behalf of the
Transferor in this matter reasonably believe that the Transferee is a "qualified
institutional buyer" as that term is defined in Rule 144A ("Rule 144A") under
the Securities Act (a "Qualified Institutional Buyer") purchasing for its own
account or for the account of another person that is itself a Qualified
Institutional Buyer. In determining whether the Transferee is a Qualified
Institutional Buyer, the Transferor and any person acting on behalf of the
Transferor in this matter has relied upon the following method(s) of
establishing the Transferee's ownership and discretionary investments of
securities (check one or more):

                  ___      (a) The Transferee's most recent publicly available
                           financial statements, which statements present the

                           the date of sale of the Transferred Certificates in
                           the case of a U.S. purchaser and within 18 months
                           preceding such date of sale in the case of a foreign
                           purchaser; or

                  ___      (b) The most recent publicly available information
                           appearing in documents filed by the Transferee with
                           the Securities and Exchange Commission or another
                           United States federal, state, or local governmental
                           agency or self-regulatory organization, or with a
                           foreign governmental agency or self-regulatory
                           organization, which information is as of a date
                           within 16 months preceding the date of sale of the
                           Transferred Certificates in the case of a U.S.
                           purchaser and within 18 months preceding such date of
                           sale in the case of a foreign purchaser; or

                  ___      (c) The most recent publicly available information
                           appearing in a recognized securities manual, which
                           information is as of a date within 16 months
                           preceding the date of sale of the Transferred
                           Certificates in the case of a U.S. purchaser and
                           within 18 months preceding such date of sale in the
                           case of a foreign purchaser; or

                  ___      (d) A certification by the chief financial officer, a
                           person fulfilling an equivalent function, or other
                           executive officer of the Transferee, specifying the
                           amount of securities owned and invested on a
                           discretionary basis by the Transferee as of a
                           specific date on or since the close of the
                           Transferee's most recent fiscal year, or, in the case
                           of a Transferee that is a member of a "family of
                           investment companies", as that term is defined in
                           Rule 144A, a certification by an executive officer of
                           the investment adviser specifying the amount of
                           securities owned by the "family of investment
                           companies" as of a specific date on or since the
                           close of the Transferee's most recent fiscal year.

                  ___      (e)      Other. (Please specify brief description
                                    of method) _________________________________
                                    ____________________________________________
                                    ___________________________________________.


                  4. The Transferor and any person acting on behalf of the
Transferor understand that in determining the aggregate amount of securities
owned and invested on a discretionary basis by an entity for purposes of
establishing whether such entity is a Qualified Institutional Buyer:

                  (a) the following instruments and interests shall be excluded:
                  securities of issuers that are affiliated with such entity;
                  securities that are part of an unsold allotment to or
                  subscription by such entity, if such entity is a dealer;
                  securities of issuers that are part of such entity's "family
                  of investment companies", if such entity is a registered
                  investment company; bank deposit notes and certificates of
                  deposit; loan participations; repurchase agreements;
                  securities owned but subject to a repurchase agreement; and
                  currency, interest rate and commodity swaps;

                  (b) the aggregate value of the securities shall be the cost of
                  such securities, except where the entity reports its
                  securities holdings in its financial statements on the basis
                  of their market value, and no current information with respect
                  to the cost of those securities has been published, in which
                  case the securities may be valued at market; and

                  (c) securities owned by subsidiaries of the entity that are
                  consolidated with the entity in its financial statements
                  prepared in accordance with generally accepted accounting
                  principles may be included if the investments of such
                  subsidiaries are managed under the direction of the entity,
                  except that, unless the entity is a reporting company under
                  Section 13 or 15(d) of the Securities Exchange Act of 1934, as
                  amended, securities owned by such subsidiaries may not be
                  included if the entity itself is a majority-owned subsidiary
                  that would be included in the consolidated financial
                  statements of another enterprise.

                  5. The Transferor or a person acting on its behalf has taken
reasonable steps to ensure that the Transferee is aware that the Transferor is
relying on the exemption from the provisions of Section 5 of the Securities Act
provided by Rule 144A.

                  6. The Transferor or a person acting on its behalf has
furnished, or caused to be furnished, to the Transferee all information
regarding (a) the Depositor, (b) the Transferred Certificates and distributions
thereon, (c) the nature, performance and servicing of the Mortgage Loans, (d)
the Pooling and Servicing Agreement, and (e) all related matters, that the
Transferee has requested.

Transferred Certificates under the Securities Act of 1933, as amended (the
"Securities Act"), 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.

                  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 any Person, 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

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 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

           [FOR TRANSFEREES THAT ARE REGISTERED INVESTMENT COMPANIES]

                  The undersigned hereby certifies as follows to [name of
Transferor] (the "Transferor"), and [name of Certificate Registrar], as
Certificate Registrar, with respect to the mortgage pass-through certificates
(the "Transferred Certificates") described in the Transferee certificate to
which this certification relates and to which this certification is an Annex:

                  1. As indicated below, the undersigned is the chief financial
officer, a person fulfilling an equivalent function, or other executive officer
of the entity purchasing the Transferred Certificates (the "Transferee") or, if
the Transferee is a "qualified institutional buyer" as that term is defined in
Rule 144A under the Securities Act of 1933, as amended ("Rule 144A") because the
Transferee is part of a Family of Investment Companies (as defined below), is an
executive officer of the investment adviser (the "Adviser").

                  2. The Transferee is a "qualified institutional buyer" as
defined in Rule 144A because (i) the Transferee is an investment company
registered under the Investment Company Act of 1940, and (ii) as marked below,
the Transferee alone owned and/or invested on a discretionary basis, or the
Transferee's Family of Investment Companies owned, at least $100,000,000 in
securities (other than the excluded securities referred to below) as of the end
of the Transferee's most recent fiscal year. For purposes of determining the
amount of securities owned by the Transferee or the Transferee's Family of
Investment Companies, the cost of such securities was used, unless the
Transferee or any member of the Transferee's Family of Investment Companies, as
the case may be, reports its securities holdings in its financial statements on
the basis of their market value, and no current information with respect to the
cost of those securities has been published, in which case the securities of
such entity were valued at market.

____     The Transferee owned and/or invested on a discretionary basis
         $___________________ in securities (other than the excluded securities
         referred to below) as of the end of the Transferee's most recent fiscal
         year (such amount being calculated in accordance with Rule 144A).

____     The Transferee is part of a Family of Investment Companies which owned
         in the aggregate $______________ in securities (other than the excluded
         securities referred to below) as of the end of the Transferee's most
         recent fiscal year (such amount being calculated in accordance with
         Rule 144A).

                  3. The term "Family of Investment Companies" as used herein
means two or more registered investment companies (or series thereof) that have
the same investment adviser or investment advisers that are affiliated (by
virtue of being majority owned subsidiaries of the same parent or because one
investment adviser is a majority owned subsidiary of the other).

                  4. The term "securities" as used herein does not include (i)
securities of issuers that are affiliated with the Transferee or are part of the
Transferee's Family of Investment Companies, (ii) bank deposit notes and
certificates of deposit, (iii) loan participations, (iv) repurchase agreements,
(v) securities owned but subject to a repurchase agreement and (vi) currency,
interest rate and commodity swaps. For purposes of determining the aggregate
amount of securities owned and/or invested on a discretionary basis by the
Transferee, or owned by the Transferee's Family of Investment Companies, the
securities referred to in this paragraph were excluded.

                  5. The Transferee is familiar with Rule 144A and understands
that the Transferor and other parties related to the Transferred Certificates
are relying and will continue to rely on the statements made herein because one
or more sales to the Transferee will be in reliance on Rule 144A.

         ___      ___       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

                  4. Neither the Transferee nor anyone acting on its behalf has

solicitation by means of general advertising or in any other manner, or (e)
taken any other action, that (in the case of any of the acts described in
clauses (a) through (e) above) would constitute a distribution of the
Transferred Certificates under the Securities Act, would render the disposition
of the Transferred Certificates a violation of Section 5 of the Securities Act
or any state securities law or would require registration or qualification of
the Transferred Certificates pursuant thereto. The Transferee will not act, nor
has it authorized nor will it authorize any person to act, in any manner set
forth in the foregoing sentence with respect to the Transferred Certificates,

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

                  foreign savings and loan association or equivalent
                  institution.

         ___      Broker-dealer. The Transferee is a dealer registered pursuant
                  to Section 15 of the Securities Exchange Act of 1934, as
                  amended.

         ___      Insurance Company. The Transferee is an insurance company
                  whose primary and predominant business activity is the writing
                  of insurance or the reinsuring of risks underwritten by
                  insurance companies and which is subject to supervision by the
                  insurance commissioner or a similar official or agency of a
                  State, U.S. territory or the District of Columbia.

         ___      State or Local Plan. The Transferee is a plan established and
                  maintained by a State, its political subdivisions, or any
                  agency or instrumentality of the State or its political
                  subdivisions, for the benefit of its employees.

         ___      ERISA Plan. The Transferee is an employee benefit plan within
                  the meaning of Title I of the Employee Retirement Income
                  Security Act of 1974.

         ___      Investment Advisor. The Transferee is an investment advisor
                  registered under the Investment Advisers Act of 1940, as
                  amended.

         ___      QIB Subsidiary. All of the Transferee's equity owners are
                  "qualified institutional buyers" within the meaning of Rule
                  144A.

         ___      Other. (Please supply a brief description of the entity and a
                  cross-reference to the paragraph and subparagraph under
                  subsection (a)(1) of Rule 144A pursuant to which it qualifies.
                  Note that registered investment companies should complete
                  Annex 2 rather than this Annex 1.)

                  3. For purposes of determining the aggregate amount of
securities owned and/or invested on a discretionary basis by the Transferee, the
Transferee did not include (i) securities of issuers that are affiliated with
such Person, (ii) securities that are part of an unsold allotment to or
subscription by such Person, if such Person is a dealer, (iii) bank deposit
notes and certificates of deposit, (iv) loan participations, (v) repurchase
agreements, (vi) securities owned but subject to a repurchase agreement and
(vii) currency, interest rate and commodity swaps.

                  4. For purposes of determining the aggregate amount of
securities owned and/or invested on a discretionary basis by any such Person,
the Transferee used the cost of such securities to such Person, unless such
Person reports its securities holdings in its financial statements on the basis
of their market value, and no current information with respect to the cost of
those securities has been published, in which case the securities were valued at
market. Further, in determining such aggregate amount, the Transferee may have
included securities owned by subsidiaries of such Person, but only if such
subsidiaries are consolidated with such Person in its financial statements
prepared in accordance with generally accepted accounting principles and if the
investments of such subsidiaries are managed under such Person's direction.
However, such securities were not included if such Person is a majority-owned,
consolidated subsidiary of another enterprise and such Person is not itself a
reporting company under the Securities Exchange Act of 1934, as amended.

                  5. The Transferee acknowledges that it is familiar with Rule
144A and understands that the Transferor and other parties related to the
Transferred Certificates are relying and will continue to rely on the statements
made herein because one or more Transfers to the Transferee may be in reliance
on Rule 144A.

         ___      ___        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 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) 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 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 acquiring any interest in the Transferred
Certificates for an account other than its own, such account belongs to a third
party that is itself a "qualified institutional buyer" within the meaning of
Rule 144A, and the "qualified institutional buyer" status of such third party
has been established by the Transferee through one or more of the appropriate
methods contemplated by Rule 144A.

                  7. The undersigned will notify the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice, the Transferee's acquisition of any interest in the
Transferred Certificates will constitute a reaffirmation of this certification
by the undersigned as of the date of such acquisition.

                  8. Capitalized terms used but not defined herein have the
meanings ascribed thereto in the Pooling and Servicing Agreement pursuant to
which the Transferred Certificates were issued.

Ladies and Gentlemen:

                  This letter is delivered to you in connection with the
Transfer by _________________ (the "Transferor") to _________________ (the
"Transferee") through our respective Depository Participants of the Transferor's
beneficial ownership interest (currently maintained on the books and records of
The Depository Trust Corporation ("DTC"), and the Depository Participants) in
the Transferred Certificates. The Certificates, including the Transferred
Certificates, were issued pursuant to the Pooling and Servicing Agreement, dated
as of March 1, 2003 (the "Pooling and Servicing Agreement"), among Credit Suisse
First Boston Mortgage Securities Corp., as depositor (the "Depositor"), Midland

certifies, represents and warrants to and agrees with you, and for the benefit
of the Depositor, that:

                  1. The Transferee is acquiring the Transferor's beneficial
         ownership interest in the Transferred Certificates for its own account
         for investment and not with a view to or for sale or transfer in
         connection with any distribution thereof, in whole or in part, in any
         manner which would violate the Securities Act of 1933, as amended (the
         "Securities Act"), or any applicable state securities laws.

                  2. The Transferee understands that (a) the Transferred
         Certificates have not been and will not be registered under the
         Securities Act or registered or qualified under any applicable state
         securities laws, (b) neither the Depositor nor the Trustee is obligated
         so to register or qualify the Transferred Certificates, and (c) neither
         the Transferred Certificates nor any security issued in exchange
         therefor or in lieu thereof may be resold or transferred unless it is
         (i) registered pursuant to the Securities Act and registered or
         qualified pursuant any applicable state securities laws, or (ii) is
         sold or transferred in transactions which are exempt from such
         registration and qualification and the Transferor desiring to effect
         such transfer has received either (A) a certificate from the
         prospective transferee substantially in the form attached either as
         Exhibit F-2C to the Pooling and Servicing Agreement or as Exhibit F-2D
         to the Pooling and Servicing Agreement or (B) an opinion of counsel
         satisfactory to the Transferor to the effect that such transfer may be
         made without registration under the Securities Act.

                  3. The Transferee understands that it may not sell or
         otherwise transfer any Transferred Certificate, any security issued in
         exchange therefor or in lieu thereof or any interest in the foregoing
         except in compliance with the provisions of Section 5.02 of the Pooling
         and Servicing Agreement, which provisions it has carefully reviewed,
         and that each Transferred Certificate will bear the following legends:

                  THIS CERTIFICATE HAS NOT BEEN REGISTERED OR QUALIFIED UNDER
                  THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT")

                  TRANSFER OR OTHER DISPOSITION OF THIS CERTIFICATE OR ANY
                  INTEREST HEREIN WITHOUT SUCH REGISTRATION OR QUALIFICATION MAY
                  BE MADE ONLY IN A TRANSACTION WHICH DOES NOT REQUIRE SUCH
                  REGISTRATION OR QUALIFICATION AND WHICH IS IN ACCORDANCE WITH
                  THE PROVISIONS OF SECTION 5.02 OF THE POOLING AND SERVICING
                  AGREEMENT REFERRED TO HEREIN.

                  NO TRANSFER OF THIS CERTIFICATE OR ANY INTEREST HEREIN MAY BE

                  APPLICABLE FEDERAL, STATE OR LOCAL LAW ("SIMILAR LAW") OR (B)
                  TO ANY PERSON WHO IS DIRECTLY OR INDIRECTLY PURCHASING THIS
                  CERTIFICATE OR SUCH INTEREST HEREIN ON BEHALF OF, AS NAMED
                  FIDUCIARY OF, AS TRUSTEE OF, OR WITH ASSETS OF, ANY SUCH
                  EMPLOYEE BENEFIT PLAN OR OTHER RETIREMENT ARRANGEMENT, EXCEPT
                  IN ACCORDANCE WITH THE PROVISIONS OF SECTION 5.02 OF THE
                  POOLING AND SERVICING AGREEMENT REFERRED TO HEREIN.

                  [THE TRUST FUND IN WHICH THIS CERTIFICATE EVIDENCES AN
                  INTEREST HAS NOT BEEN REGISTERED AS AN "INVESTMENT COMPANY"
                  UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (THE
                  "INVESTMENT COMPANY ACT"). ACCORDINGLY, NEITHER THIS
                  CERTIFICATE NOR ANY INTEREST HEREIN MAY BE RESOLD, PLEDGED OR
                  OTHERWISE TRANSFERRED EXCEPT TO (1) A QUALIFIED INSTITUTIONAL
                  BUYER WITHIN THE MEANING OF RULE 144A UNDER THE SECURITIES ACT
                  (A "QUALIFIED INSTITUTIONAL BUYER") OR (2) AN ACCREDITED
                  INVESTOR WITHIN THE MEANING OF PARAGRAPH (1), (2), (3) OR (7)
                  OF RULE 501(a) OF REGULATION D UNDER THE SECURITIES ACT OR AN
                  ENTITY IN WHICH ALL THE EQUITY OWNERS ARE DESCRIBED BY SUCH
                  PARAGRAPHS (AN "INSTITUTIONAL ACCREDITED INVESTOR").]

                  4. Neither the Transferee nor anyone acting on its behalf has
         (a) offered, pledged, sold, disposed of or otherwise transferred any
         Transferred Certificate, any interest in any Transferred Certificate or
         any other similar security to any person in any manner, (b) solicited
         any offer to buy or accept a pledge, disposition or other transfer of
         any Transferred Certificate, any interest in any 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 any 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 any Transferred Certificate or any other similar security
         by means of general advertising or in any other manner, or (e) taken
         any other action with respect to any Transferred Certificate, any
         interest in any Transferred Certificate or any other similar security,
         which (in the case of any of the acts described in clauses (a) through
         (e) above) would constitute a distribution of the Transferred
         Certificates under the Securities Act, would render the disposition of
         the Transferred Certificates a violation of Section 5 of the Securities
         Act or any state securities law or would require registration or
         qualification of the Transferred Certificates pursuant thereto. The
         Transferee will not act, nor has it authorized or will it authorize any
         person to act, in any manner set forth in the foregoing sentence with
         respect to any Transferred Certificate, any interest in any Transferred
         Certificate or any other similar security.

                  5. The Transferee has been furnished with all information
         regarding (a) the Depositor, (b) the Transferred Certificates and
         distributions thereon, (c) the Pooling and Servicing Agreement and the
         Trust Fund created pursuant thereto, (d) the nature, performance and
         servicing of the Mortgage Loans, and (e) all related matters, that it
         has requested.

                  6. The Transferee is an "accredited investor" as defined in
         any of paragraphs (1), (2), (3), and (7) of Rule 501(a) under the
         Securities Act or an entity in which all of the equity owners come
         within such paragraphs. The Transferee has such knowledge and
         experience in financial and business matters as to be capable of
         evaluating the merits and risks of an investment in the Transferred
         Certificates; the Transferee has sought such accounting, legal and tax
         advice as it has considered necessary to make an informed investment
         decision; and the Transferee is able to bear the economic risks of such
         investment and can afford a complete loss of such investment.

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-CPN1, Class [R] [LR], 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 Interest Certificates, and (ii)
is acquiring the Residual Interest Certificates for its own account or for the
account of another prospective transferee from which it has received an
affidavit in substantially the same form as this affidavit. A "Permitted
Transferee" is any Person other than a Disqualified Organization, a possession
of the United States, Non-United States Tax Person or domestic partnership whose
beneficial interests are not all held by United States Tax Person. (For this
purpose, a "Disqualified Organization" means the United States, any state or
political subdivision thereof, any agency or instrumentality of any of the
foregoing (other than an instrumentality, all of the activities of which are
subject to tax and, except for the Federal Home Loan Mortgage Corporation, a
majority of whose board of directors is not selected by any such governmental
entity) or any foreign government, international organization or any agency or
instrumentality of such foreign government or organization, any rural electric
or telephone cooperative, or any organization (other than certain farmers'
cooperatives) that is generally exempt from federal income tax unless such
organization is subject to the tax on unrelated business taxable income).

                  3. The Transferee is aware (i) of the tax that would be
imposed under the Code on transfers of the Residual Interest Certificates to
non-Permitted Transferees; (ii) that such tax would be on the transferor or, if
such transfer is through an agent (which Person includes a broker, nominee or
middleman) for a non-Permitted Transferee, on the agent; (iii) that the Person
otherwise liable for the tax shall be relieved of liability for the tax if the
transferee furnishes to such Person an affidavit that the transferee is a
Permitted Transferee and, at the time of transfer, such Person does not have
actual knowledge that the affidavit is false; and (iv) that the Residual
Interest Certificates may be a "noneconomic residual interest" within the
meaning of Treasury regulation Section 1.860E-1(c), and that the transferor of a
noneconomic residual interest will remain liable for any taxes due with respect
to the income on such residual interest, unless no significant purpose of the
transfer is to enable the transferor to impede the assessment or collection of
tax.

                  4. The Transferee is aware of the tax imposed on a
"pass-through entity" holding the Residual Interest Certificates if at any time
during the taxable year of the pass-through entity a non-Permitted Transferee is
the record holder of an interest in such entity. (For this purpose, a
"pass-through entity" includes a regulated investment company, a real estate
investment trust or common trust fund, a partnership, trust or estate, and
certain cooperatives.)

                  5. The Transferee is aware that the Certificate Registrar will
not register any transfer of the Residual Interest Certificates by the
Transferee unless the Transferee's transferee, or such transferee's agent,
delivers to the Certificate Registrar, among other things, an affidavit and
agreement in substantially the same form as this affidavit and agreement. The
Transferee expressly agrees that it will not consummate any such transfer if it
knows or believes that any representation contained in such affidavit and
agreement is false.

                  6. The Transferee consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Residual Interest Certificates will
only be owned, directly or indirectly, by a Permitted Transferee.

                  7. The Transferee's taxpayer identification number is
_________________.

                  8. The Transferee has reviewed the provisions of Section
5.02(d) of the Pooling and Servicing Agreement, a description of which
provisions is set forth in the Residual Interest Certificates (in particular,
clause (ii)(A) of Section 5.02(d) which authorizes the Trustee to deliver
payments on the Residual Interest Certificates to a Person other than the
Transferee and clause [(ii)(B)] of Section 5.02(d) which authorizes the Trustee
to negotiate a mandatory sale of the Residual Interest Certificates, in either
case, in the event that the Transferee holds such Residual Interest Certificates
in violation of Section 5.02(d)); and the Transferee expressly agrees to be
bound by and to comply with such provisions.

                  9. The Transferee 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.

                  10. The Transferee will not cause income from the Residual
Interest Certificate to be attributable to a foreign permanent establishment or
fixed base, within the meaning of an applicable income tax treaty, of the
Transferee or any other United States Person.

                  11. Check the applicable paragraph:

                  [ ] The present value of the anticipated tax liabilities
associated with holding the Residual Interest Certificate does not exceed the
sum of:

                           (i)      the present value of any consideration given
                                    to the Transferee to acquire such Residual
                                    Interest Certificate;

                           (ii)     the present value of the expected future
                                    distributions on such Residual Interest
                                    Certificate; and

                           (iii)    the present value of the anticipated tax
                                    savings associated with holding such
                                    Residual Interest Certificates as the
                                    related Trust REMIC generates losses.

For purposes of this calculation, (i) the Transferee is assumed to pay tax at
the highest rate currently specified in Section 11(b) of the Code (but the tax
rate in Section 55(b)(1)(B) of the Code may be used in lieu of the highest rate
specified in Section 11(b) of the Code if the Transferee has been subject to the
alternative minimum tax under Section 55 of the Code in the preceding two years
and will compute its taxable income in the current taxable year using the
alternative minimum tax rate) and (ii) present values are computed using a
discount rate equal to the short-term Federal rate prescribed by Section 1274(d)
of the Code for the month of the transfer and the compounding period used by the
Transferee.

                  [ ] The transfer of the Residual Interest Certificate complies
with U.S. Treasury Regulations Sections 1.860E-1(c)(5) and (6) and, accordingly,

                           (i)      the Transferee is an "eligible corporation,"
                                    as defined in U.S. Treasury Regulations
                                    Section 1.860E-1(c)(6)(i), as to which
                                    income from the Residual Interest
                                    Certificates will only be taxed in the
                                    United States;

                           (ii)     at the time of the transfer, and at the
                                    close of the Transferee's two fiscal years
                                    preceding the year of the transfer, the
                                    Transferee had gross assets for financial
                                    reporting purposes (excluding any obligation
                                    of a person related to the Transferee within
                                    the meaning of U.S. Treasury Regulations
                                    Section 1.860E-1(c)(6)(ii)) in excess of
                                    $100 million and net assets in excess of $10
                                    million;

                           (iii)    the Transferee will transfer the Residual
                                    Interest Certificates only to another
                                    "eligible corporation," as defined in U.S.
                                    Treasury Regulations Section
                                    1.860E-1(c)(6)(i), in a transaction that
                                    satisfies the requirements of Sections
                                    1.860E-1(c)(4)(i), (ii) and (iii) and
                                    Section 1.860E-1(c)(5) of the U.S. Treasury
                                    Regulations; and

                           (iv)     the Transferee determined the consideration
                                    paid to it to acquire the Residual Interest
                                    Certificates based on reasonable market
                                    assumptions (including, but not limited to,
                                    borrowing and investment rates, prepayment
                                    and loss assumptions, expense and

                                    other factors specific to the Transferee)
                                    that it has determined in good faith.

                  [ ] None of the above.

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.

                           ____% 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 the Pooling and
Servicing Agreement, dated as of March 1, 2003 (the "Pooling and Servicing
Agreement"), among Credit Suisse First Boston Mortgage Securities Corp., as
depositor, Midland Loan Services, Inc., as general master servicer (the "General
Master Servicer"), and general special servicer (the "General Special
Servicer"), NCB, FSB, as co-op master servicer (the "Co-op Master Servicer"),
National Consumer Cooperative Bank, as co-op special servicer (the "Co-op
Special Servicer"), and Wells Fargo Bank Minnesota, N.A. as Trustee (the
"Trustee"). All capitalized terms used but not otherwise defined herein shall
have the respective meanings set forth in the Pooling and Servicing Agreement.
The Transferor hereby certifies, represents and warrants to you, as Certificate
Registrar, that:

                  1. No purpose of the Transferor relating to the transfer of
the Residual Interest Certificates by the Transferor to the Transferee is or
will be to impede the assessment or collection of any tax.

                  2. The Transferor understands that the Transferee has
delivered to you a Transfer Affidavit and Agreement in the form attached to the
Pooling and Servicing Agreement as Exhibit H-1. The Transferor does not know or
believe that any representation contained therein is false.

                  3. The Transferor has at the time of this transfer conducted a
reasonable investigation of the financial condition of the Transferee (or the
beneficial owners of the Transferee if the Transferee is classified as a
partnership under the Code) as contemplated by Treasury regulation Section
1.860E-1(c)(4)(i), and, as a result of that investigation, the Transferor has
determined that the Transferee has historically paid its debts as they became
due and has found no significant evidence to indicate that the Transferee will
not continue to pay its debts as they become due in the future. The Transferor
understands that the transfer of the Residual Interest Certificates may not be
respected for United States income tax purposes (and the Transferor may continue
to be liable for United States income taxes associated therewith) unless the
Transferor has conducted such an investigation.


                                            Very truly yours,

THIS Agreement made this _____ day of ___, 20__, between [_______], a

W I T N E S S E T H:
--------------------
WHEREAS, Superior Mortgagee is the owner of a certain $__________ mortgage and
note secured thereby, dated ________ __, ____, made by
__________________________________ (the "Borrower") to Subordinate Mortgagee
(the "Superior Mortgage") covering the premises located at
____________________________________________ more particularly described in the
Superior Mortgage and Schedule "A" attached hereto (the "Premises"); and
WHEREAS, Subordinate Mortgagee is the holder of a certain $____________ mortgage
and the note secured thereby, dated ________ __, ____, made by the Borrower to
Subordinate Mortgagee (the "Subordinate Mortgage") covering the Premises; and
WHEREAS, the Superior Mortgagee has purchased the Superior Mortgage from
Subordinate Mortgagee and as a condition thereto has required that the
Subordinate Mortgage be fully subordinated to the Superior Mortgage.

NOW, THEREFORE, the parties hereto agree as follows:
The Subordinate Mortgagee hereby covenants and agrees that (i) the Subordinate
Mortgage and all of its terms and provisions and the loan it secures are and
shall remain in all respects subject and subordinate to the Superior Mortgage,
its lien and all of its terms and provisions and to the loan it secures and to
any modifications, consolidations, extension or renewals thereof and to any
increases therein resulting from advances to protect or preserve the lien of the
Superior Mortgage on the Premises encumbered thereby but not any other increases
therein; (ii) no tenant under any lease of any portion of the Premises, other
than tenant shareholders under proprietary leases, will be made a party
defendant in any foreclosure of the Subordinate Mortgage, nor will any other
action be taken in connection with such foreclosure which would have the effect
of terminating any such lease; (iii) no portion of the accounts, accounts
receivable, rents, issues and profits of the Premises shall be collected in
connection with the foreclosure of the Subordinate Mortgage or any other
enforcement action except through a receiver appointed by the court in which
such foreclosure action is brought, after due notice of the application of the
appointment of such receiver shall have been given to the Superior Mortgagee;
(iv) the accounts, accounts receivable, rents, issues and profits collected by
any such receiver (or which shall under any circumstances come into possession
of the holder of the Subordinate Mortgage at a time when Subordinate Mortgagee
has received written notice of a default under the Superior Mortgage) shall be
applied first to the payment of taxes, maintenance and operating charges and
disbursements incurred in connection with the operation and maintenance of the
Premises, and next to the payment of principal and interest due under the
Superior Mortgage at the time of such application, before any portion of such
accounts, accounts receivable, rents, issues and profits shall be applied to the
Subordinate Mortgage; (v) during the pendency of any such foreclosure action, if
an action shall be brought for the foreclosure of the Superior Mortgage and an
application shall be made for an extension of such receivership for the benefit
of the Superior Mortgagee, the Subordinate Mortgagee shall consent to the
extension of such receivership and all accounts, accounts receivable, rents,
issues and profits held by such receiver as of the date of such application
shall be applied by the receiver solely for the benefit of the Superior
Mortgagee, and the Subordinate Mortgagee in their respective order of priority;
(vi) due notice of the commencement of any foreclosure of the Subordinate
Mortgage shall be given to the Superior Mortgagee and true copies of all papers
served or entered in such action will be delivered to the Superior Mortgagee
upon such service or entry; (vii) no payments shall be made to the holder of the
Subordinate Mortgage during the period in which any default exists under the
Superior Mortgage in respect of any monthly payment or balloon payment due
thereunder beyond any applicable grace period, provided that the Subordinate
Mortgagee has received written notice of such default and all payments otherwise
payable to the Subordinate Mortgagee during such period shall be paid to the
Superior Mortgagee and, if any such payments are received by the Subordinate
Mortgagee at any time after which the Subordinate Mortgagee has received written
notice of the existence of such default, they shall be held in trust for the
Superior Mortgagee and turned over to the Superior Mortgagee on demand; (viii)
any distributions made or to be made to the Subordinate Mortgagee pursuant to
any bankruptcy or insolvency proceeding of the borrower representing amounts due
under the Superior Mortgagee shall be paid by the borrower, or, if such payments
are nonetheless received by the Subordinate Mortgagee, by the Subordinate
Mortgagee immediately upon their receipt, to the Superior Mortgagee for
application against the principal amounts due under the Superior Mortgage in
reverse order of maturity; and (ix) all condemnation, casualty or similar
payments with respect to the premises shall be applied, for so long as the
Superior Mortgage remains outstanding, in accordance with the Superior Mortgage.
This Agreement is governed by and is to be construed under the laws of the State
of New York.
This Agreement shall not be amended or modified except by an agreement in
writing, signed by the party against whom enforcement is sought.

Except for notices in a foreclosure action, which shall be given as provided by
applicable rule of court, all notices hereunder shall be given to each party in
the same manner as provided in its mortgage or, if there are no such notice
provisions, at the address set forth above by personal delivery or first class,
certified mail, return receipt requested. Notices shall be deemed to have been
given when received. Either party may change its address for notices hereunder
by written notice to the other party.

This Agreement shall be binding upon the parties hereto and their respective
heirs, successors and assigns. Any assignee of the Subordinate Mortgage shall be
deemed by acceptance thereof to have assumed the obligations of Subordinate
