corporation (the "Depositor").

                                    RECITALS

      I. Capitalized terms used herein without definition have the meanings
ascribed to them in the Schedule of Transaction Terms attached hereto as
Schedule I, which is incorporated herein by this reference, or, if not defined
therein, in the Pooling and Servicing Agreement.

      II. On the Closing Date, and on the terms set forth herein, Seller has
agreed to sell to Depositor and Depositor has agreed to purchase from Seller the
Mortgage Loans identified on the schedules (collectively, the "Mortgage Loan
Schedule") annexed hereto as Schedule II-A and Schedule II-B. Depositor intends
to deposit the Mortgage Loans and other assets into the Trust Fund created
pursuant to the Pooling and Servicing Agreement and to cause the issuance of the
Certificates.

                                    AGREEMENT

      NOW, THEREFORE, on the terms and conditions set forth below and for good
and valuable consideration, the receipt and adequacy of which is hereby
acknowledged, Depositor, Seller and PNC Bank (acting in its capacity as the
servicer of the Mortgage Loans identified on Schedule II-B prior to the Closing
and for the limited purposes set forth in Section 23 below) agree as follows:

      Section 1. Transactions on or Prior to the Closing Date. On or prior to
the Closing Date, Seller shall have delivered the Mortgage Files with respect to
each of the Mortgage Loans listed in the Mortgage Loan Schedule to LaSalle Bank
National Association as trustee (the "Trustee") or its designee, against receipt
by Seller of a written receipt, pursuant to an arrangement between Seller and
the Trustee; provided, however, that item (p) in the definition of Mortgage File
(below) shall be delivered to the Master Servicer for inclusion in the Servicer
File (defined below) with a copy delivered to the Trustee for inclusion in the
Mortgage File; provided further, that the Seller shall pay (or cause the related
Borrower to pay) any costs of the assignment or amendment of each letter of
credit described under item (p) required in order for the Master Servicer to
draw on such letter of credit pursuant to the terms of the Pooling and Servicing
Agreement and shall deliver the related assignment or amendment documents within

the terms of the Pooling and Servicing Agreement, including, if necessary,
drawing on the letter of credit in its own name pursuant to written instructions
to draw from the Master Servicer and upon receipt, immediately remitting the
proceeds of such draw (or causing such proceeds to be remitted) to the Master
Servicer.

      designated by Seller on or prior to the Closing Date. The "Mortgage Loan
      Purchase Price" paid by Depositor shall be equal to $____________. In
      addition, for no consideration other than the Mortgage Loan Purchase
      Price, the Seller shall acquire, or cause a nominee to acquire, Seller's
      proportionate share of the residual Certificates under the Pooling and
      Servicing Agreement.

            (ii) Pursuant to the terms of the Pooling and Servicing Agreement,
      Depositor shall sell all of its right, title and interest in and to the
      Mortgage Loans to the Trustee for the benefit of the Holders of the
      Certificates.

            (iii) Depositor shall sell to the Underwriters, and the Underwriters

      Notwithstanding the foregoing, in the event that, in connection with any
Mortgage Loan, the Seller cannot deliver, or cause to be delivered, an original,
counterpart or certified copy of any of the documents required to be delivered
pursuant to clauses (b), (d), (h), (k) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement), (l) and (n) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement) above with evidence of recording or filing thereon on the
Closing Date, solely because of a delay caused by the public recording or filing
office where such document or instrument has been delivered for recordation or
filing, the Seller shall deliver, or cause to be delivered, to the Trustee or
its designee a duplicate original or true copy of such document certified by the
applicable public recording or filing office, the applicable title insurance
company or the Seller to be a true and complete duplicate original or copy of
the original thereof submitted for recording or filing.

      Notwithstanding the foregoing, in the event that, in connection with any
Mortgage Loan, the Seller cannot deliver, or cause to be delivered, an original,
counterpart or certified copy of any of the documents required to be delivered
pursuant to clauses (b), (d), (h), (k) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement), (l) and (n) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement) above with evidence of recording or filing thereon, for any
other reason, including without limitation, that such non-delivered document has
been lost, the delivery requirements of this Agreement shall be deemed to have
been satisfied and such non-delivered document shall be deemed to have been
included in the related Mortgage File if a photocopy of such non-delivered
document (with evidence of recording or filing thereon and certified by the
appropriate recording or filing office to be a true and complete copy of the
original thereof as filed or recorded) is delivered to the Trustee or its
designee on or before the Closing Date.

      Notwithstanding the foregoing, in the event that the Seller cannot deliver
to the Trustee or its designee any UCC-2 or UCC-3 assignment with the filing
information of the UCC-1 financing statement with respect to any Mortgage Loan
being assigned, solely because such UCC-1 financing statement has not been
returned by the public filing office where such UCC-1 financing statement has
been delivered for filing, Seller shall deliver or cause to be delivered to the
Trustee or its designee a photocopy of such UCC-2 or UCC-3 assignment with the
filing information left blank. The Seller, promptly upon receipt of the
applicable filing information of the UCC-1 financing statement being so
assigned, shall deliver or cause to be delivered to the Trustee or its designee
the original UCC-2 or UCC-3 assignment with all appropriate filing information
set forth thereon.

      Notwithstanding the foregoing, Seller may, at its sole cost and expense,
engage a third party contractor to prepare or complete in proper form for filing
or recording any and all assignments of Mortgage, assignments of Assignments of
Leases and assignments of UCC financing statements to the Trustee to be
delivered pursuant to clauses (c), (e), (k) and (n) above (collectively, the
"Assignments"), to submit the Assignments for filing and recording, as the case
may be, in the applicable public filing and recording offices and to deliver the
Assignments to the Trustee or its designee as the Assignments (or certified
copies thereof) are received from the applicable filing and recording offices
with evidence of such filing or recording indicated thereon. However, in the
event the Seller engages a third party contractor as contemplated in the
immediately preceding sentence, the rights, duties and obligations of the Seller
pursuant to this Agreement remain binding on the Seller.

      Within ten (10) Business Days after the Closing Date, the Seller shall
deliver the Servicer Files with respect to each of the Mortgage Loans to the
Master Servicer or if applicable, a Primary Servicer (with a copy to the Master
Servicer) under the direction of the Master Servicer, under the Pooling and
Servicing Agreement on behalf of the Trustee in trust for the benefit of the
Certificateholders. Each such Servicer File shall contain all documents and
records in the Seller's possession relating to such applicable Mortgage Loans
(including reserve and escrow agreements, cash management agreements, lockbox
agreements, financial statements and any other information provided by the
respective Borrower from time to time, but excluding any documents and other
writings not enumerated in this parenthetical that have been prepared by the
Seller or any of its Affiliates solely for internal communication) that are not
required to be a part of a Mortgage File in accordance with the definition
thereof, together with copies of all instruments and documents which are
required to be a part of the related Mortgage File in accordance with the
definition thereof.

      For purposes of this Section 3, and notwithstanding any contrary provision
hereof or of the definition of "Mortgage File", if there exists with respect to
any group of Crossed Loans only one original or certified copy of any document
or instrument described in the definition of "Mortgage File" which pertains to
all of the Crossed Loans in such group of Crossed Loans, the inclusion of the
original or certified copy of such document or instrument in the Mortgage File
for any of such Crossed Loans and the inclusion of a copy of such original or
certified copy in each of the Mortgage Files for the other Crossed Loans in such
group of Crossed Loans, shall be deemed the inclusion of such original or
certified copy, as the case may be, in the Mortgage File for each such Crossed
Loan.

      The Trustee, as assignee or transferee of Depositor, shall be entitled to
all scheduled principal payments due after the Cut-off Date, all other payments
of principal due and collected after the Cut-off Date, and all payments of
interest on the Mortgage Loans, minus that portion of any such payment which is
allocable to the period on or prior to the Cut-off Date. All scheduled payments
of principal due on or before the Cut-off Date and collected after the Cut-off
Date, together with the accompanying interest payments, shall belong to Seller.

      Upon the sale of the Mortgage Loans from Seller to Depositor pursuant
hereto, the ownership of each Note, the related Mortgage and the contents of the
related Mortgage File shall be vested in Depositor and the ownership of all
records and documents with respect to the related Mortgage Loan prepared by or
which come into the possession of Seller as seller of the Mortgage Loans
hereunder, exclusive in each case of documents prepared by Seller or any of its
Affiliates solely for internal uses, shall immediately vest in Depositor. All
Monthly Payments, Principal Prepayments and other amounts received by Seller and
not otherwise belonging to Seller pursuant to this Agreement shall be sent by
Seller within three (3) Business Days after Seller's receipt thereof to the
Master Servicer via wire transfer for deposit by the Master Servicer into the
Collection Account.

      Section 4. Depositor's Conditions to Closing. The obligations of Depositor
to purchase the Mortgage Loans and pay the Mortgage Loan Purchase Price at the
Closing Date under the terms of this Agreement are subject to the satisfaction
of each of the following conditions at or before the Closing:

servicer of the Mortgage Loans identified on Schedule II-B prior to the Closing)
under this Agreement (subject to the exceptions set forth in the applicable
Exception Report) shall be true and correct in all material respects as of the
Closing Date; no event shall have occurred with respect to the Seller or any of
the Mortgage Loans and related Mortgage Files which, with notice or the passage
of time, would constitute a material default under this Agreement; and Depositor
shall have received certificates to the foregoing effect signed by authorized
officers of Seller.

      (b) Depositor, or if directed by Depositor, the Trustee or the Depositor's
attorneys or other designee, shall have received in escrow, all of the following
closing documents, in such forms as are agreed upon and reasonably acceptable to
the Depositor and the Seller, duly executed by all signatories other than
Depositor, as required pursuant to the respective terms thereof:

            (i) the Mortgage Files, subject to the provisos of Section 1 of this
      Agreement, which shall have been delivered to and held by the Trustee or

opinions to matters governed by the General Corporation Law of the State of

qualification of the Certificates under any applicable state or federal
securities laws.

      Such counsel shall state that, although such counsel has not specifically

required;

            (vi) such other certificates of Seller's officers or others and such
      other documents to evidence fulfillment of the conditions set forth in
      this Agreement as Depositor or its counsel may reasonably request; and

      (c) The Seller shall have performed or complied with all other terms and
conditions of this Agreement which it is required to perform or comply with at

      evidence fulfillment of the conditions set forth in this Agreement as
      Seller or its counsel may reasonably request.

      (c) The Depositor shall have performed or complied with all other terms
and conditions of this Agreement which it is required to perform or comply with
at or before the Closing and shall have the ability to perform or comply with
all duties, obligations, provisions and terms which it is required to perform or
comply with after Closing.

      Section 6. Representations and Warranties of Seller.

      (a) Seller represents and warrants to Depositor as of the date hereof, as
follows:

            (i) Seller is duly organized and is validly existing as a
      corporation in good standing under the laws of the State of Delaware.
      Seller has conducted and is conducting its business so as to comply in all
      material respects with all applicable statutes and regulations of
      regulatory bodies or agencies having jurisdiction over it, except where
      the failure so to comply would not have a materially adverse effect on the
      performance by Seller of this Agreement, and there is no charge, action,
      suit or proceeding before or by any court, regulatory authority or
      governmental agency or body pending or, to the knowledge of Seller,
      threatened, which is reasonably likely to materially and adversely affect
      the performance by Seller of this Agreement or the consummation of
      transactions contemplated by this Agreement.

            (ii) Seller has the full power, authority and legal right to hold,
      transfer and convey the Mortgage Loans and to execute and deliver this
      Agreement (and all agreements and documents executed and delivered by
      Seller in connection herewith) and to perform all transactions of Seller
      contemplated by this Agreement (and all agreements and documents executed
      and delivered by Seller in connection herewith). Seller has duly
      authorized the execution, delivery and performance of this Agreement (and
      all agreements and documents executed and delivered by Seller in
      connection herewith), and has duly executed and delivered this Agreement
      (and all agreements and documents executed and delivered by Seller in
      connection herewith). This Agreement (and each agreement and document
      executed and delivered by Seller in connection herewith), assuming due
      authorization, execution and delivery thereof by each other party thereto,
      constitutes the legal, valid and binding obligation of Seller enforceable
      in accordance with its terms, except as such enforcement may be limited by
      bankruptcy, fraudulent transfer, insolvency, reorganization, receivership,
      moratorium or other laws relating to or affecting the rights of creditors
      generally, by general principles of equity (regardless of whether such
      enforcement is considered in a proceeding in equity or at law) and by
      considerations of public policy.

            (iii) Neither the execution, delivery and performance of this
      Agreement, nor the fulfillment of or compliance with the terms and
      conditions of this Agreement by Seller, will (a) conflict with or result
      in a breach of any of the terms, conditions or provisions of Seller's
      certificate of incorporation, as amended, or other organizational
      documents; (b) conflict with, result in a breach of, or constitute a
      default or result in an acceleration under, any agreement or instrument to
      which Seller is now a party or by which it (or any of its properties) is
      bound if compliance therewith is necessary (1) to ensure the
      enforceability of this Agreement or (2) for Seller to perform its duties
      and obligations under this Agreement (or any agreement or document
      executed and delivered by Seller in connection herewith); (c) conflict
      with or result in a breach of any legal restriction if compliance
      therewith is necessary (1) to ensure the enforceability of this Agreement
      or (2) for Seller to perform its duties and obligations under this
      Agreement (or any agreement or document executed and delivered by Seller
      in connection herewith); (d) result in the violation of any law, rule,
      regulation, order, judgment or decree to which Seller or its property is
      subject if compliance therewith is necessary (1) to ensure the
      enforceability of this Agreement or (2) for Seller to perform its duties
      and obligations under this Agreement (or any agreement or document
      executed and delivered by Seller in connection herewith); or (e) result in
      the creation or imposition of any lien, charge or encumbrance that would
      have a material adverse effect upon Seller's ability to perform its duties
      and obligations under this Agreement (or any agreement or document
      executed and delivered by Seller in connection herewith), or materially
      impair the ability of the Depositor to realize on the Mortgage Loans.

            (iv) Seller is solvent and the sale of Mortgage Loans (1) will not
      cause Seller to become insolvent and (2) is not intended by Seller to
      hinder, delay or defraud any of its creditors.

            (v) No consent, approval, authorization or order of, or registration
      or filing with, or notice to, any court or governmental agency or body
      having jurisdiction or regulatory authority over Seller is required for
      (a) Seller's execution, delivery and performance of this Agreement (and
      each agreement and document executed and delivered by Seller in connection
      herewith), (b) Seller's transfer and assignment of the Mortgage Loans, or
      (c) the consummation by Seller of the transactions contemplated by this
      Agreement (and each agreement and document executed and delivered by
      Seller in connection herewith) or, to the extent so required, such
      consent, approval, authorization, order, registration, filing or notice
      has been obtained, made or given (as applicable), except that Seller may
      not be duly qualified to transact business as a foreign corporation or
      licensed in one or more states if such qualification or licensing is not
      necessary to ensure the enforceability of this Agreement (or any agreement
      or document executed and delivered by Seller in connection herewith).

            (vi) The consideration received by Seller upon the sale of the
      Mortgage Loans constitutes fair consideration and reasonably equivalent
      value for such Mortgage Loans.

            (vii) Seller does not believe, nor does it have any reason or cause
      to believe, that it cannot perform each and every covenant of Seller
      contained in this Agreement (or any agreement or document executed and
      delivered by Seller in connection herewith).

            (viii) There are no actions, suits proceedings pending or to
      Seller's knowledge threatened in writing against Seller which are
      reasonably likely to draw into question the validity of this Agreement (or
      any agreement or document executed and delivered by Seller in connection
      herewith) or which, either in any one instance or in the aggregate, are
      reasonably likely to materially impair the ability of Seller to perform
      its duties and obligations under this Agreement (or any agreement or
      document executed and delivered by Seller in connection herewith).

            (ix) Seller's performance of its duties and obligations under this
      Agreement (and each agreement or document executed and delivered by Seller
      in connection herewith) is in the ordinary course of business of Seller
      and Seller's transfer, assignment and conveyance of the Mortgage Loans
      pursuant to this Agreement are not subject to the bulk transfer or similar
      statutory provisions in effect in any applicable jurisdiction.

            (x) Seller has not dealt with any Person that may be entitled, by
      reason of any act or omission of Seller, to any commission or compensation
      in connection with the sale of the Mortgage Loans to the Depositor
      hereunder except for the reimbursement of expenses as described herein or
      otherwise in connection with the transactions described in Section 2 and
      the commissions or compensation owed to the Underwriters or the Initial
      Purchaser.

            (xi) Seller is not in default or breach of any agreement or
      instrument to which Seller is now a party or by which it (or any of its
      properties) is bound which breach or default would materially and
      adversely affect the ability of Seller to perform its obligations under
      this Agreement.

            (xii) The representations and warranties contained in Exhibit A and
      the exceptions to such representations and warranties set forth on
      Schedule V-A hereto are true and correct in all material respects as of
      the date hereof with respect to the Mortgage Loans identified on Schedule
      II-A; provided, however, that any reference to the Mortgage Loan Schedule
      in paragraph (xxx) of Exhibit A shall be read as a reference to Schedule
      II-A.

            (xiii) The representations and warranties set forth in paragraph
      (i), paragraph (iii), paragraph (iv), the first sentence of paragraph
      (vii), paragraph (viii), the second sentence of paragraph (xxii), the
      fourth sentence of paragraph (xxvii), paragraph (xlvi) (with respect to
      the Seller on or after June 28, 2002), paragraph (xlvii), and paragraph
      (lvii) of Exhibit A are true and correct in all material respects as of
      the date hereof with respect to the Mortgage Loans identified on Schedule
      II-B.

      (b) PNC Bank, acting in its capacity as the servicer of the Mortgage Loans
identified on Schedule II-B prior to the Closing, represents and warrants to
Depositor as of the date hereof, as follows:

            (i) PNC Bank is duly organized and is validly existing as a national
      banking association in good standing under the laws of the United States
      of America. PNC Bank has conducted and is conducting its business so as to
      comply in all material respects with all applicable statutes and
      regulations of regulatory bodies or agencies having jurisdiction over it,
      except where the failure so to comply would not have a materially adverse
      effect on the performance by PNC Bank of this Agreement, and there is no
      charge, action, suit or proceeding before or by any court, regulatory
      authority or governmental agency or body pending or, to the knowledge of
      PNC Bank, threatened, which is reasonably likely to materially and
      adversely affect the performance by PNC Bank of this Agreement or the
      consummation of transactions contemplated by this Agreement.

            (ii) PNC Bank has the full power, authority and legal right to
      execute and deliver this Agreement (and all agreements and documents
      executed and delivered by PNC Bank in connection herewith) and to perform
      all transactions of PNC Bank contemplated by this Agreement (and all
      agreements and documents executed and delivered by PNC Bank in connection
      herewith). PNC Bank has duly authorized the execution, delivery and
      performance of this Agreement (and all agreements and documents executed
      and delivered by PNC Bank in connection herewith), and has duly executed
      and delivered this Agreement (and all agreements and documents executed
      and delivered by PNC Bank in connection herewith). This Agreement (and
      each agreement and document executed and delivered by PNC Bank in
      connection herewith), assuming due authorization, execution and delivery
      thereof by each other party thereto, constitutes the legal, valid and
      binding obligation of PNC Bank enforceable in accordance with its terms,
      except as such enforcement may be limited by bankruptcy, fraudulent
      transfer, insolvency, reorganization, receivership, moratorium or other
      laws relating to or affecting the rights of creditors generally, by
      general principles of equity (regardless of whether such enforcement is
      considered in a proceeding in equity or at law) and by considerations of
      public policy.

            (iii) Neither the execution, delivery and performance of this
      Agreement, nor the fulfillment of or compliance with the terms and
      conditions of this Agreement by PNC Bank, will (a) conflict with or result
      in a breach of any of the terms, conditions or provisions of PNC Bank's
      articles of association, as amended, or other organizational documents;
      (b) conflict with, result in a breach of, or constitute a default or
      result in an acceleration under, any agreement or instrument to which PNC
      Bank is now a party or by which it (or any of its properties) is bound if
      compliance therewith is necessary (1) to ensure the enforceability of this
      Agreement or (2) for PNC Bank to perform its duties and obligations under
      this Agreement (or any agreement or document executed and delivered by PNC
      Bank in connection herewith); (c) conflict with or result in a breach of
      any legal restriction if compliance therewith is necessary (1) to ensure
      the enforceability of this Agreement or (2) for PNC Bank to perform its
      duties and obligations under this Agreement (or any agreement or document
      executed and delivered by PNC Bank in connection herewith); (d) result in
      the violation of any law, rule, regulation, order, judgment or decree to
      which PNC Bank or its property is subject if compliance therewith is
      necessary (1) to ensure the enforceability of this Agreement or (2) for
      PNC Bank to perform its duties and obligations under this Agreement (or
      any agreement or document executed and delivered by PNC Bank in connection
      herewith); or (e) result in the creation or imposition of any lien, charge
      or encumbrance that would have a material adverse effect upon PNC Bank's
      ability to perform its duties and obligations under this Agreement (or any
      agreement or document executed and delivered by PNC Bank in connection
      herewith), or materially impair the ability of the Depositor to realize on
      the Mortgage Loans.

            (iv) PNC Bank is solvent and the execution, delivery and performance
      of this Agreement by PNC Bank (1) will not cause PNC Bank to become
      insolvent and (2) is not intended by PNC Bank to hinder, delay or defraud
      any of its creditors.

            (v) No consent, approval, authorization or order of, or registration
      or filing with, or notice to, any court or governmental agency or body
      having jurisdiction or regulatory authority over PNC Bank is required for
      (a) PNC Bank's execution, delivery and performance of this Agreement (and
      each agreement and document executed and delivered by PNC Bank in
      connection herewith) and (b) the consummation by PNC Bank of the
      transactions contemplated by this Agreement (and each agreement and
      document executed and delivered by PNC Bank in connection herewith) or, to
      the extent so required, such consent, approval, authorization, order,
      registration, filing or notice has been obtained, made or given (as
      applicable), except that PNC Bank may not be duly qualified to transact
      business as a foreign corporation or licensed in one or more states if
      such qualification or licensing is not necessary to ensure the
      enforceability of this Agreement (or any agreement or document executed
      and delivered by PNC Bank in connection herewith).

            (vi) [Reserved]

            (vii) PNC Bank does not believe, nor does it have any reason or
      cause to believe, that it cannot perform each and every covenant of PNC
      Bank contained in this Agreement (or any agreement or document executed
      and delivered by PNC Bank in connection herewith).

            (viii) There are no actions, suits proceedings pending or to PNC
      Bank's knowledge threatened in writing against PNC Bank which are
      reasonably likely to draw into question the validity of this Agreement (or
      any agreement or document executed and delivered by PNC Bank in connection
      herewith) or which, either in any one instance or in the aggregate, are
      reasonably likely to materially impair the ability of PNC Bank to perform
      its duties and obligations under this Agreement (or any agreement or
      document executed and delivered by PNC Bank in connection herewith).

            (ix) PNC Bank's performance of its duties and obligations under this
      Agreement (and each agreement or document executed and delivered by PNC
      Bank in connection herewith) is in the ordinary course of business of PNC
      Bank.

            (x) PNC Bank has not dealt with any Person that may be entitled, by
      reason of any act or omission of PNC Bank, to any commission or
      compensation in connection with the sale of the Mortgage Loans by the
      Seller to the Depositor hereunder.

            (xi) PNC Bank is not in default or breach of any agreement or
      instrument to which PNC Bank is now a party or by which it (or any of its
      properties) is bound which breach or default would materially and
      adversely affect the ability of PNC Bank to perform its obligations under
      this Agreement.

            (xii) The representations and warranties set forth in paragraph
      (ii), paragraph (v), paragraph (vi), paragraph (vii) (excluding the first
      sentence of said paragraph), paragraphs (ix) through (xxi), inclusive,
      paragraph (xxii) (excluding the second sentence of said paragraph),
      paragraphs (xxiii) through (xxvi), inclusive, paragraph (xxvii) (excluding
      the fourth sentence of said paragraph), paragraphs (xxviii) through (xlv),
      inclusive, paragraph (xlvi) (with respect to PNC Bank and any prior holder
      of the related Note, if any, on or before June 28, 2002), paragraphs
      (xlviii) through (lvi), inclusive, paragraph (lviii), and paragraph (lix)
      of Exhibit A (including the preamble language contained in Exhibit A
      appearing prior to paragraph (i) thereof) and the exceptions to such
      representations and warranties set forth on Schedule V-B hereto are true
      and correct in all material respects as of the date hereof with respect to
      the Mortgage Loans identified on Schedule II-B; provided, however, that
      all references in such representations and warranties to the Seller or the
      Seller's knowledge shall be read as references to PNC Bank (or its
      knowledge) acting in its capacity as the servicer of such Mortgage Loans
      prior to the Closing; provided further that any reference to the Mortgage
      Loan Schedule in paragraph (xxx) of Exhibit A shall be read as a reference
      to Schedule II-B.

            (xiii) The representations and warranties set forth in paragraph
      (i), paragraph (iii), paragraph (iv), and paragraph (viii) of Exhibit A

      material respects as of June 28, 2002 with respect to the Mortgage loans
      identified on Schedule II-B hereto.

      Section 7. Obligations of Seller and PNC Bank. Each of the representations
and warranties contained in or required to be made by an Applicable Party
pursuant to Section 6 of this Agreement shall survive the sale of the Mortgage
Loans and shall continue in full force and effect, notwithstanding any
restrictive or qualified endorsement on the Notes and notwithstanding subsequent
termination of this Agreement or the Pooling and Servicing Agreement. The
representations and warranties contained in or required to be made by an
Applicable Party pursuant to Section 6 of this Agreement shall not be impaired
by any review or examination of the Mortgage Files or other documents evidencing
or relating to the Mortgage Loans or any failure on the part of Depositor to
review or examine such documents and shall inure to the benefit of the initial
transferee of the Mortgage Loans from Depositor including, without limitation,
the Trustee for the benefit of the Holders of the Certificates, notwithstanding
(1) any restrictive or qualified endorsement on any Note, assignment of Mortgage
or reassignment of Assignment of Leases or (2) any termination of this Agreement
prior to the Closing but shall not inure to the benefit of any subsequent
transferee thereafter.

      If any Certificateholder, the Master Servicer, the Special Servicer or the
Trustee discovers or receives notice: of a breach of (a) any of the
representations or warranties made by the Seller with respect to the Mortgage
Loans (subject to the exceptions to such representations and warranties set
forth in the applicable Exception Report), as of the date hereof in Section
6(a)(xii) and Section 6(a)(xiii) or as of the Closing Date pursuant to Section
4(b)(iii) or (b) any of the representations or warranties made by PNC Bank,
acting in its capacity as the servicer of the Mortgage Loans identified on
Schedule II-B prior to the Closing, with respect to such Mortgage Loans (subject
to the exceptions to such representations and warranties set forth in the
applicable Exception Report), as of the date hereof in Section 6(b)(xii) and
Section 6(b)(xiii) or as of the Closing Date pursuant to Section 4(b)(iv)
(clause (a) and clause (b) each, a "Breach"); or that (c) any document required
to be included in the Mortgage File related to any Mortgage Loan is not in the
Trustee's (or its designee's) possession within the time period required herein
or (d) such document has not been properly executed or is otherwise defective on
its face (clause (c) and clause (d) each, a "Defect" (including the "Defects"
described below) in the related Mortgage File), such party shall give notice to
the Master Servicer, the Special Servicer, the Trustee and the Rating Agencies.
If the Master Servicer or the Special Servicer determines that such Breach or
Defect materially and adversely affects the value of any Mortgage Loan or REO
Loan or the interests of the Holders of any Class of Certificates, it shall give
prompt written notice of such Breach or Defect to the Depositor, the Trustee,
the Master Servicer, the Special Servicer, the Seller and the Applicable Party
(if different from the Seller) and shall request that the Applicable Party not
later than the earlier of 90 days from the receipt by the Applicable Party of
such notice or discovery by the Applicable Party of such Breach or Defect
(subject to the second succeeding paragraph, the "Initial Resolution Period"),
(i) cure such Breach or Defect in all material respects; (ii) repurchase the
affected Mortgage Loan at the applicable Purchase Price (as defined in the
Pooling and Servicing Agreement) or (iii) substitute one or more Qualified
Substitute Mortgage Loans (as defined in the Pooling and Servicing Agreement)
for such affected Mortgage Loan (provided that in no event shall any
substitution occur later than the second anniversary of the Closing Date) and
pay the Master Servicer for deposit into the Collection Account any Substitution
Shortfall Amount (as defined in the Pooling and Servicing Agreement) in
connection therewith; provided, however, that if (i) such material Breach or
material Defect is capable of being cured but not within the Initial Resolution
Period, (ii) such material Breach or material Defect does not cause the related
Mortgage Loan not to be a "qualified mortgage" (within the meaning of Section
860G(a)(3) of the Code), (iii) the Applicable Party has commenced and is
diligently proceeding with the cure of such material Breach or material Defect
within the Initial Resolution Period and (iv) the Applicable Party has delivered
to the Rating Agencies and the Trustee an Officer's Certificate that describes
the reasons that the cure was not effected within the Initial Resolution Period
and the actions that it proposes to take to effect the cure and that states that
it anticipates the cure will be effected within the additional 90-day period,
then the Applicable Party shall have an additional 90 days to cure such material
Defect or material Breach. If any Breach pertains to a representation or
warranty that the related 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 Party shall cure such Breach within the Initial
Resolution Period by reimbursing the Trust Fund (by wire transfer of immediately
available funds) the reasonable amount of any such costs and expenses incurred
by the Master Servicer, the Special Servicer, the Trustee or the Trust Fund 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 Applicable Party shall have the option to either repurchase
the related Mortgage Loan at the applicable Purchase Price or pay such costs and
expenses. Except as provided in the proviso to the immediately preceding
sentence, the Applicable Party shall remit the amount of such costs and expenses
and upon its making such remittance, the Applicable Party shall be deemed to
have cured such Breach in all respects. With respect to any substitution of one
or more Qualified Substitute Mortgage Loans for a Mortgage Loan hereunder, (A)
no such substitution may be made in any calendar month after the Determination
Date for such month; (B) scheduled payments of principal and interest due with
respect to the Qualified Substitute Mortgage Loan(s) after the related date of
substitution shall be part of the Trust Fund; and (C) scheduled payments of
principal and interest due with respect to such Qualified Substitute Mortgage
Loan(s) on or prior to the related date of substitution shall not be part of the
Trust Fund, and the Applicable Party shall be entitled to receive such payments
promptly following receipt by the Master Servicer or Special Servicer, as
applicable, under the Pooling and Servicing Agreement.

      Any of the following will cause a document in the Mortgage File to be
deemed to have a "Defect" and to be conclusively presumed to materially and
adversely affect the interests of the Holders of a Class of Certificates and the
value of a Mortgage Loan or REO Loan: (a) the absence from the Mortgage File of
the original signed Note, unless the Mortgage File contains a signed lost note
affidavit and indemnity; (b) the absence from the Mortgage File of the original
signed Mortgage, unless there is included in the Mortgage File a certified copy
of the Mortgage as recorded or as sent for recordation, together with a
certificate stating that the original signed Mortgage was sent for recordation,
or a copy of the Mortgage and the related recording information; (c) the absence
from the Mortgage File of the item called for by paragraph (i) of the definition
of Mortgage File; (d) the absence from the Mortgage File of any intervening
assignments required to create an effective assignment to the Trustee on behalf
of the Trust, unless there is included in the Mortgage File a certified copy of
the intervening assignment and a certificate stating that the original
intervening assignments were sent for recordation; or (e) the absence from the
Servicer File of any required original letter of credit (as required in the
provisos to Section 1 hereof), provided that such Defect may be cured by any
substitute letter of credit or cash reserve or (f) the absence from the Mortgage
File of an original or copy of any required ground lease. In addition, the
Applicable Party shall cure any Defect described in clause (b), (c), (e) or (f)
of the immediately preceding sentence as required in Section 2.02(b) of the
Pooling and Servicing Agreement.

      Any Defect or Breach which causes any Mortgage Loan not to be a "qualified
mortgage" (within the meaning of Section 860G(a)(3) of the Code) shall be deemed
to materially and adversely affect the interests of the Holders of a Class of
Certificates and the Initial Resolution Period for the affected Mortgage Loan
shall be 90 days following the earlier of the Applicable Party's receipt of
notice pursuant to this Section 7 or its discovery of such Defect or Breach
(which period shall not be subject to extension).

      If the Applicable Party does not, as required by this Section 7, correct
or cure a material Breach or a material Defect in all material respects within
the applicable Initial Resolution Period (as extended pursuant to this Section
7), or if such Breach or Defect is not capable of being so corrected or cured
with such period, then the Applicable Party shall purchase or substitute for the
affected Mortgage Loan as provided in this Section 7. If (i) any Mortgage Loan
is required to be repurchased or substituted for as provided above, (ii) such
Mortgage Loan is a Crossed Loan that is a part of a Mortgage Group (as defined
below) and (iii) the applicable Breach or Defect does not constitute a Breach or
Defect, as the case may be, as to any other Crossed Loan in such Mortgage Group
(without regard to this paragraph), then the applicable Breach or Defect, as the
case may be, will be deemed to constitute a Breach or Defect, as the case may
be, as to any other Crossed Loan in the Mortgage Group for purposes of the above
provisions, and the Applicable Party will be required to repurchase or
substitute for such other Crossed Loan(s) in the related Mortgage Group in
accordance with the provisions of this Section 7 unless such other Crossed Loans
satisfy the Crossed Loan Repurchase Criteria (as defined in the Pooling and
Servicing Agreement) and the Applicable Party can satisfy all other criteria for
substitution or repurchase of the affected Mortgage Loan set forth in the
Pooling and Servicing Agreement. In the event that one or more of such other
Crossed Loans satisfy the Crossed Loan Repurchase Criteria, the Applicable Party
may elect either to repurchase or substitute for only the affected Crossed Loan
as to which the related Breach or Defect exists or to repurchase or substitute
for all of the Crossed Loans in the related Mortgage Group. The Applicable Party
shall be responsible for the cost of any Appraisal required to be obtained by
the Master Servicer to determine if the Crossed Loan Repurchase Criteria have
been satisfied, so long as the scope and cost of such Appraisal has been
approved by the Applicable Party (such approval not to be unreasonably
withheld). For purposes of this paragraph, a "Mortgage Group" is any group of
Mortgage Loans identified as a Mortgage Group on Schedule III to this Agreement.

      Notwithstanding the foregoing, if there is a material Breach or material
Defect with respect to one or more Mortgaged Properties (but not all of the
Mortgaged Properties) with respect to a Mortgage Loan, the Applicable Party will
not be obligated to repurchase or substitute for the Mortgage Loan if the
affected Mortgaged Property may be released pursuant to the terms of any partial
release provisions in the related Mortgage Loan Documents and the remaining
Mortgaged Property(ies) satisfy the requirements, if any, set forth in the
Mortgage Loan Documents and (i) the Applicable Party provides an opinion of
counsel to the effect that such partial release would not cause an Adverse REMIC
Event (as defined in the Pooling and Servicing Agreement) to occur, (ii) such
Applicable Party pays (or causes to be paid) the applicable release price
required under the Mortgage Loan Documents, and to the extent not reimbursable
out of the release price pursuant to the related Mortgage Loan Documents,
together with any additional amounts necessary to cover all reasonable
out-of-pocket expenses reasonably incurred by the Master Servicer, the Special
Servicer, the Trustee or the Trust Fund in connection therewith, including any
unreimbursed advances and interest thereon made with respect to the Mortgaged
Property which is being released and (iii) such cure by release of such
Mortgaged Property is effected within the time periods specified for cure of a
material Breach or material Defect in this Section 7.

      The Purchase Price or Substitution Shortfall Amount for any repurchased or
substituted Mortgage Loan shall be payable to the Depositor or, subsequent to
the assignment of the Mortgage Loans to the Trustee, the Trustee as its
assignee, by wire transfer of immediately available funds to the account
designated by the Depositor or the Trustee, as the case may be, and the
Depositor or the Trustee, as the case may be, upon receipt of such funds, shall
promptly release the related Mortgage File and Servicer File or cause them to be
released, to the Applicable Party and shall execute and deliver such instruments
of transfer or assignment as shall be necessary to vest in the Applicable Party
the legal and beneficial ownership of such Mortgage Loan (including any property
acquired in respect thereof or proceeds of any insurance policy with respect
thereto) and the related Mortgage Loan Documents.

      It is understood and agreed that the obligations of the Applicable Party
set forth in this Section 7 to cure, substitute for or repurchase a Mortgage
Loan constitute the sole remedies available to the Depositor and its successors
and assigns respecting any Breach or Defect affecting such Mortgage Loan.

      It is further understood and agreed that with respect to the Mortgage
Loans identified on Schedule II-B, Section 7 of the PNC Loan Sale Agreement
(subject to the limitations set forth therein) provides the sole remedies
available to the Depositor and its successors and assigns respecting any breach
of the representations and warranties made by PNC Bank with respect to such
Mortgage Loans as set forth in the PNC Loan Sale Agreement or its failure to
deliver any required Mortgage Loan Document (or its delivery of any such
Mortgage Loan Document in defective condition) to the Seller on June 28, 2002,
and neither the Depositor nor any successor or assign of the Depositor shall
have any remedies against the Seller with respect to any such breach or defect.

      Section 8. Crossed Loans. With respect to any Crossed Loan conveyed
hereunder, to the extent that the Applicable Party repurchases or substitutes
for an affected Crossed Loan in the manner prescribed above while the Trustee
continues to hold any related Crossed Loans, the Applicable Party and the
Depositor (on behalf of its successors and assigns) agree to modify upon such
repurchase or substitution, the related Mortgage Loan Documents in a manner such
that such affected Crossed Loan repurchased or substituted by the Applicable
Party, on the one hand, and any related Crossed Loans still held by the Trustee,
on the other, would no longer be cross-defaulted or cross-collateralized with
one another; provided, that the Applicable Party shall have furnished to the
Trustee, at its expense, with an Opinion of Counsel that such modification shall
not cause an Adverse REMIC Event; provided, further, that if such Opinion of
Counsel cannot be furnished, the Applicable Party and the Depositor hereby agree
that such repurchase or substitution of only the affected Crossed Loans,
notwithstanding anything to the contrary herein, shall not be permitted. Any
reserve or other cash collateral or letters of credit securing the Crossed Loans
shall be allocated between such Mortgage Loans in accordance with the Mortgage
Loan Documents. All other terms of the Mortgage Loans shall remain in full force
and effect, without any modification thereof.

(and by each of the parties hereto on different counterparts), each of which

will be deemed to constitute but one and the same instrument.

      Section 21. Treatment as Security Agreement. It is the express intent of
the parties hereto that the conveyance of the Mortgage Loans by Seller to
Depositor as provided in this Agreement be, and be construed as, a sale of the
Mortgage Loans by Seller to Depositor. It is, further, not the intention of the
parties that such conveyance be deemed a pledge of the Mortgage Loans by Seller
to Depositor to secure a debt or other obligation of Seller. However, in the
event that, notwithstanding the intent of the parties, the Mortgage Loans are
held to be property of Seller or if for any reason this Agreement is held or
deemed to create a security interest in the Mortgage Loans:

      (a) this Agreement shall hereby create a security agreement within the
meaning of Articles 8 and 9 of the Uniform Commercial Code in effect in the
applicable state;

      (b) the conveyance provided for in this Agreement shall hereby grant from
Seller to Depositor a security interest in and to all of Seller's right, title,
and interest, whether now owned or hereafter acquired, in and to:

            (i) all accounts, contract rights (including any guarantees),
      general intangibles, chattel paper, instruments, documents, money, deposit
      accounts, certificates of deposit, goods, letters of credit, advices of
      credit and investment property consisting of, arising from or relating to
      any of the property described in the Mortgage Loans, including the related
      Notes, Mortgages and title, hazard and primary mortgage insurance policies
      identified on the Mortgage Loan Schedule, including all replacement
      Mortgage Loans, and all distributions with respect thereto payable after
      the Cut-off Date;

            (ii) all accounts, contract rights, general intangibles, chattel
      paper, instruments, documents, money, deposit accounts, certificates of
      deposit, goods, letters of credit, advices of credit and investment
      property arising from or by virtue of the disposition of, or collections
      with respect to, or insurance proceeds payable with respect to, or claims
      against other persons with respect to, all or any part of the collateral
      described in (i) above (including any accrued discount realized on
      liquidation of any investment purchased at a discount), in each case,
      payable after the Cut-off Date; and

            (iii) all cash and non-cash proceeds of the collateral described in
      (i) and (ii) above payable after the Cut-off Date;

      (c) the possession by Depositor or its assignee of the Notes and such
other goods, letters of credit, advices of credit, instruments, money,
documents, chattel paper or certificated securities shall be deemed to be
possession by the secured party or possession by a purchaser or a person
designated by him or her, for purposes of perfecting the security interest
pursuant to the Uniform Commercial Code (including, without limitation, Sections
9-306, 9-313 and 9-314 thereof) as in force in the relevant jurisdiction; and

      (d) notifications to persons holding such property, and acknowledgments,
receipts, confirmations from persons holding such property, shall be deemed to
be notifications to, or acknowledgments, receipts or confirmations from,
financial intermediaries, bailees or agents of, or persons holding for (as
applicable), Depositor or its assignee for the purpose of perfecting such
security interest under applicable law. The Seller at the direction of the
Depositor or its assignee, shall, to the extent consistent with this Agreement,
take such actions as may be necessary to ensure that, if this Agreement were
deemed to create a security interest in the Mortgage Loans and the proceeds
thereof, such security interest would be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of this Agreement. In connection herewith, Depositor and its assignee shall have
all of the rights and remedies of a secured party and creditor under the Uniform
Commercial Code as in force in the relevant jurisdiction.

      Section 22. Recordation of Agreement. To the extent permitted by
applicable law, this Agreement is subject to recordation following the Closing
Date in all appropriate public offices for real property records in all the
counties or other comparable jurisdictions in which any or all of the properties
subject to the Mortgages are situated, and in any other appropriate public
recording office or elsewhere, such recordation to be effected by Seller at
Seller's expense at the direction of Depositor accompanied by an Opinion of
Counsel to the effect that such recordation materially and beneficially affects
the interests of Depositor.

      Section 23. PNC Bank as a Party. PNC Bank is executing and delivering this
Agreement and any additional certificates and documents in connection herewith
solely in its capacity as the servicer of the Mortgage Loans identified on
Schedule II-B prior to the Closing and solely for the purpose of making the
representations and warranties set forth in Section 6(b) (including Exhibit A,
Schedule II-B and Schedule V-B), incurring the obligations set forth in Section
7 and agreeing to the matters related to such representations, warranties and
obligations set forth in Sections 8, 14, 16 and Schedule I.

                         REPRESENTATIONS AND WARRANTIES
                          REGARDING THE MORTGAGE LOANS

            For purposes of these representations and warranties, the phrase "to
the knowledge of the Seller" or "to the Seller's knowledge" shall mean, except
where otherwise expressly set forth below, the actual state of knowledge of the
Seller or any servicer acting on its behalf regarding the matters referred to,
in each case without having conducted any independent inquiry or due diligence
with respect to such matters and without any actual or implied obligation to
make such inquiry or perform such due diligence, other than making such inquiry
or performing such due diligence as would be customarily performed by prudent
commercial or multifamily mortgage lenders or servicers (as the case may be)
with respect to similar mortgage loans or mortgaged properties. All information
contained in documents which are part of or required to be part of a Mortgage
File shall be deemed to be within the knowledge of the Seller. Wherever there is
a reference to receipt by, or possession of, the Seller of any information or
documents, or to any action taken by the Seller or not taken by the Seller, such
reference shall include the receipt or possession of such information or
documents by, or the taking of such action or the not taking of such action by,
either the Seller or any servicer acting on its behalf.

            The Seller hereby represents and warrants, subject to the exceptions
set forth in the applicable Exception Report, with respect to the Mortgage Loans
that as of the date hereinbelow specified or, if no such date is specified, as
of the date of this Agreement:

                  (i) Immediately prior to the sale, transfer and assignment to
            the Depositor, no Note or Mortgage was subject to any assignment
            (other than assignments which show a complete chain of assignment to
            the Seller), participation or pledge, and the Seller had good and
            marketable title to, and was the sole owner of, the related Mortgage
            Loan;

                  (ii) Each Mortgage Loan was either:

                        (A) originated by a savings and loan association,
                  savings bank, commercial bank, credit union, or insurance
                  company, which is supervised and examined by a Federal or
                  State authority, or by a mortgagee approved by the Secretary
                  of Housing and Urban Development pursuant to Sections 203 and
                  211 of the National Housing Act (any of the foregoing,
                  including the Seller, a "Qualified Originator"); or

                        (B) if originated by a person which is not a Qualified
                  Originator (any such person, a "Non-Qualified Originator"),
                  then:

                              (1) such Mortgage Loan was underwritten in
                        accordance with standards established by a Qualified
                        Originator, using application forms and related credit
                        documents approved by the Qualified Originator;

                              (2) the Qualified Originator approved each
                        application and related credit documents before a
                        commitment by the Non-Qualified Originator was issued,
                        and no such commitment was issued until the Qualified
                        Originator agreed to fund such Mortgage Loan;

                              (3) the Mortgage Loan was originated by the
                        Non-Qualified Originator pursuant to an ongoing,
                        standing relationship with the Qualified Originator; and

                              (4) the closing documents for the Mortgage Loan
                        were prepared on forms approved by the Qualified
                        Originator, and, pursuant to the Non-Qualified
                        Originator's ongoing, standing relationship with the
                        Qualified Originator, either:

                                    (a) such closing documents reflect the
                              Qualified Originator as the original mortgagee,
                              and such Mortgage Loan was actually funded by the
                              Qualified Originator at the closing thereof;

                                    (b) such closing documents reflect the
                              Non-Qualified Originator as the original

                              closing of the Mortgage Loan, reflecting the
                              Qualified Originator as the successor and assign

                              Originator at the closing thereof and then
                              acquired by the Qualified Originator from such

                                    (c) such closing documents reflect the
                              Non-Qualified Originator as the original
                              mortgagee, but include assignment documents
                              executed by the Non-Qualified Originator in favor

                              to the Non-Qualified Originator, and the Mortgage
                              Loan was funded initially by the Qualified
                              Originator at the closing thereof and then
                              acquired by the Qualified Originator from such
                              Non-Qualified Originator.

                        and binding assignment of such Mortgage Loan;

                              (iv) The Seller is transferring such Mortgage Loan
                        free and clear of any and all liens, pledges, charges or

                              (v) To Seller's knowledge, based on the related
                        borrower's representations and covenants in the related
                        mortgage loan documents and such other due diligence as
                        a reasonably prudent commercial mortgage lender would

                        authorizations then required for use of the Mortgaged
                        Property which were valid and in full force and effect
                        as of the origination date and to Seller's actual
                        knowledge, such licenses, permits and authorizations are
                        still valid and in full force and effect;

                              (vi) Each related Note, Mortgage, assignment of
                        leases (if any) and other agreement executed by or for

                        bankruptcy, insolvency, reorganization, moratorium or
                        other laws affecting the enforcement of creditors'
                        rights or by general principles of equity (regardless of
                        whether such enforceability is considered in a
                        proceeding in equity or at law); and there is no right
                        of offset, rescission, abatement or diminution or valid
                        defense or counterclaim available to the related
                        borrower with respect to such Note, Mortgage, Assignment

                        insolvency, reorganization, moratorium or other laws
                        affecting the enforcement of creditors' rights or by
                        general principles of equity (regardless of whether such

                        enforcement of creditors' rights or by general
                        principles of equity (regardless of whether such
                        enforceability is considered in a proceeding in equity

                        affecting the enforcement of creditors' rights or by
                        general principles of equity (regardless of whether such
                        enforceability is considered in a proceeding in equity
                        or at law);

                        subordinated or rescinded in whole or in part and (b)
                        each related Mortgaged Property has not been released,
                        in whole or in part, from the lien of the related
                        Mortgage in any manner which materially interferes with

                        the terms of, or the security for, the Mortgage Loan in
                        any material respect has occurred or been given;

                              (x) Each related Mortgage is a valid and
                        enforceable first lien on the related Mortgaged Property
                        (subject to Permitted Encumbrances (as defined below)),

                        bankruptcy, insolvency, reorganization, moratorium or
                        other laws affecting the enforcement of creditors'
                        rights or by general principles of equity (regardless of
                        whether such enforceability is considered in a
                        proceeding in equity or at law); and such Mortgaged
                        Property is free and clear of any mechanics' and
                        materialmen's liens which are prior to or equal with the
                        lien of the related Mortgage, except those which are
                        insured against by a lender's title insurance policy (as
                        described below). A UCC financing statement has been
                        filed and/or recorded (or sent for filing or recording)
                        in all places necessary to perfect a valid security
                        interest in the personal property necessary to operate
                        the Mortgaged Property as currently operated; and such
                        security interest is a first priority security interest,

                        such personal property, any personal property leases
                        applicable to such personal property and any other
                        security interest in such personal property which do
                        not, individually or in the aggregate, materially
                        interfere with the security intended to be provided for
                        such Mortgage Loan. Any security agreement, chattel
                        mortgage or equivalent document related to and delivered
                        in connection with the Mortgage Loan establishes and
                        creates a valid and enforceable lien on the property
                        described therein, except as such enforcement may be
                        limited by bankruptcy, insolvency, reorganization,
                        moratorium or other laws affecting the enforcement of
                        creditors' rights or by general principles of equity
                        (regardless of whether such enforceability is considered
                        in a proceeding in equity or at law). In the case of any
                        Mortgage Loan secured by a hotel, the related loan
                        documents contain such provisions as are necessary and
                        UCC Financing Statements have been filed as necessary,
                        in each case, to perfect a valid first priority security
                        interest in the related operating revenues with respect
                        to such Mortgaged Property. Notwithstanding the
                        foregoing, no representation is made as to the
                        perfection of any security interest in rent, operating
                        revenues or other personal property to the extent that
                        possession or control of such items or actions other
                        than the filing of Uniform Commercial Code financing
                        statements are required in order to effect such
                        perfection;

                              (xi) The Seller has not taken any action that
                        would cause the representations and warranties made by
                        the related borrower in the related Mortgage Loan
                        Documents not to be true;

                              (xii) The Seller has no knowledge that the
                        material representations and warranties made by the
                        related borrower in the related Mortgage Loan Documents
                        are not true in any material respect;

                              (xiii) The lien of each related Mortgage is a
                        first priority lien on the fee or leasehold interest of
                        the related borrower in the principal amount of such
                        Mortgage Loan or allocated loan amount of the portions
                        of the Mortgaged Property covered thereby (as set forth
                        in the related Mortgage) after all advances of principal
                        and is insured by an ALTA lender's title insurance
                        policy (except that if such policy is yet to be issued,
                        such insurance may be evidenced by a "marked up" pro
                        forma policy or title commitment in either case marked
                        as binding and countersigned by the title company or its
                        authorized agent, either on its face or by an
                        acknowledged closing instruction or escrow letter), or
                        its equivalent as adopted in the applicable
                        jurisdiction, insuring the lender and its successors and
                        assigns (as sole insured) as to such lien, subject only
                        to (a) the lien of current real property taxes, water
                        charges, sewer rents and assessments not yet delinquent
                        or accruing interest or penalties, (b) covenants,
                        conditions and restrictions, rights of way, easements
                        and other matters of public record, none of which,
                        individually or in the aggregate, materially interferes
                        with the current use of the Mortgaged Property or the
                        security intended to be provided by such Mortgage or
                        with the borrower's ability to pay its obligations when
                        they become due or the value of the Mortgaged Property
                        and (c) the exceptions (general and specific) and
                        exclusions set forth in such policy, none of which,
                        individually or in the aggregate, materially interferes
                        with the current general use of the Mortgaged Property
                        or materially interferes with the security intended to
                        be provided by such Mortgage or with the related
                        borrower's ability to pay its obligations when they
                        become due or the value of the Mortgaged Property (items
                        (a), (b) and (c) collectively, "Permitted Encumbrances")
                        and with respect to each Mortgage Loan, such Permitted
                        Encumbrances do not, individually or in the aggregate,
                        materially interfere with the security intended to be
                        provided by the related Mortgage, the current principal
                        use of the related Mortgaged Property or the current
                        ability of the related Mortgaged Property to generate
                        income sufficient to service such Mortgage Loan; the
                        premium for such policy was paid in full; such policy
                        (or if it is yet to be issued, the coverage to be
                        afforded thereby) is issued by a title insurance company
                        licensed to issue policies in the state in which the
                        related Mortgaged Property is located (unless such state
                        is Iowa) and is assignable (with the related Mortgage
                        Loan) to the Depositor and the Trustee without the
                        consent of or any notification to the insurer, and is in
                        full force and effect upon the consummation of the
                        transactions contemplated by the Mortgage Loan Purchase
                        Agreement; no claims have been made under such policy
                        and the Seller has not undertaken any action or omitted
                        to take any action, and has no knowledge of any such act
                        or omission, which would impair or diminish the coverage
                        of such policy;

                              (xiv) The proceeds of such Mortgage Loan have been
                        fully disbursed and there is no requirement for future
                        advances thereunder, and no future advances have been
                        made which are not reflected in the related Mortgage
                        File;

                              (xv) Except as set forth in a property inspection
                        report or engineering report prepared in connection with
                        the origination of the Mortgage Loan, as of the later of
                        the date of origination of such Mortgage Loan or the
                        most recent inspection of the related Mortgaged Property
                        by the Seller, as applicable, and to the knowledge of
                        Seller as of the date hereof, each related Mortgaged
                        Property is free of any material damage that would
                        affect materially and adversely the use or value of such
                        Mortgaged Property as security for the Mortgage Loan
                        (normal wear and tear excepted). If any of the
                        inspection or engineering reports referred to above in
                        this Paragraph (xv) revealed any immediate repair items,
                        then one of the following is true: (a) the repairs
                        and/or maintenance necessary to correct such condition
                        have been completed in all material respects; (b) an
                        escrow of funds is required or a letter of credit was
                        obtained in an amount reasonably estimated to be
                        sufficient to complete the repairs and/or maintenance
                        necessary to correct such condition; or (c) the
                        reasonable estimation at the time of origination of the
                        Mortgage Loan of the cost to complete the repairs and/or
                        maintenance necessary to correct such condition
                        represented no more than the greater of (i) $50,000 and
                        (ii) 2% of the value of the related Mortgaged Property
                        as reflected in an appraisal conducted in connection
                        with the origination of the subject Mortgage Loan; as of
                        the closing date for each Mortgage Loan and, to the
                        Seller's knowledge, as of the date hereof, there is no
                        proceeding pending for the total or partial condemnation
                        of such Mortgaged Property that would have a material
                        adverse effect on the use or value of the Mortgaged
                        Property;

                              (xvi) The Seller has inspected or caused to be
                        inspected each related Mortgaged Property within the
                        past twelve months, or the originator of the Mortgage
                        Loan inspected or caused to be inspected each related
                        Mortgaged Property within three months of origination of
                        the Mortgage Loan;

                              (xvii) No Mortgage Loan has a shared appreciation
                        feature, any other contingent interest feature or a
                        negative amortization feature other than the ARD Loans
                        which may have negative amortization from and after the
                        Anticipated Repayment Date;

                              (xviii) Each Mortgage Loan is a whole loan and
                        neither the Mortgage Loan nor the related Mortgage Loan
                        Documents create or grant an equity participation to the
                        lender or any other party;

                              (xix) The Mortgage Rate (exclusive of any default
                        interest, late charges, or prepayment premiums) of such
                        Mortgage Loan complied as of the date of origination
                        with, or was exempt from, applicable state or federal
                        laws, regulations and other requirements pertaining to
                        usury. Except to the extent any noncompliance did not
                        materially and adversely affect the value of the related
                        Mortgaged Property, the security provided by the
                        Mortgage or the related borrower's operations at the
                        related Mortgaged Property, any and all other
                        requirements of any federal, state or local laws,
                        including, without limitation, truth-in-lending, real
                        estate settlement procedures, equal credit opportunity
                        or disclosure laws, applicable to such Mortgage Loan
                        have been complied with as of the date of origination of
                        such Mortgage Loan;

                              (xx) Neither the Seller nor to the Seller's
                        knowledge, any originator, committed any fraudulent acts
                        during the origination process of any Mortgage Loan and
                        the origination, servicing and collection of each
                        Mortgage Loan is in all respects legal, proper and
                        prudent in accordance with customary commercial mortgage
                        lending standards, and no other person has been granted
                        or conveyed the right to service the Mortgage Loans or
                        receive any consideration in connection therewith,
                        except as provided in the Pooling and Servicing
                        Agreement or any permitted subservicing agreements;

                              (xxi) All taxes and governmental assessments that
                        became due and owing prior to the date hereof with
                        respect to each related Mortgaged Property and that are
                        or may become a lien of priority equal to or higher than
                        the lien of the related Mortgage have been paid or an
                        escrow of funds has been established and such escrow
                        (including all escrow payments required to be made prior
                        to the delinquency of such taxes and assessments) is
                        sufficient to cover the payment of such taxes and
                        assessments;

                              (xxii) All escrow deposits and payments required
                        pursuant to each Mortgage Loan are in the possession, or
                        under the control, of Column Financial, Inc. or its
                        agent and there are no deficiencies (subject to any
                        applicable grace or cure periods) in connection
                        therewith. All such escrows and deposits are being
                        conveyed by Column Financial, Inc. to the Depositor and
                        identified as such with appropriate detail. With respect
                        to any disbursements made from such escrows, any
                        requirements for the disbursement of any such escrows
                        have been complied with in all material respects;

                              (xxiii) Each related Mortgaged Property is insured
                        by a fire and extended perils insurance policy, issued
                        by an insurer meeting the requirements of the Pooling
                        and Servicing Agreement, in an amount not less than the
                        lesser of the principal amount of the related Mortgage
                        Loan and the replacement cost (with no deduction for
                        physical depreciation) and not less than the amount
                        necessary to avoid the operation of any co-insurance
                        provisions with respect to the related Mortgaged
                        Property; each related Mortgaged Property is also
                        covered by business interruption or rental loss
                        insurance which covers a period of not less than 12
                        months and comprehensive general liability insurance in
                        amounts generally required by prudent commercial
                        mortgage lenders for similar properties; all Mortgaged
                        Properties in California or in a seismic zone 4 or 5
                        have had a seismic assessment done and earthquake
                        insurance was obtained to the extent any such Mortgaged
                        Property has a probable maximum loss in the event of an
                        earthquake of greater than twenty percent (20%) of the
                        replacement value of the related improvements; if the
                        Mortgaged Property for any Mortgage Loan is located
                        within Florida or within 25 miles of the coast of North
                        Carolina, South Carolina, Georgia, Alabama, Mississippi,
                        Louisiana or Texas, then, such Mortgaged Property is
                        insured by windstorm insurance in an amount at least
                        equal to the lesser of (i) the outstanding principal
                        balance of such Mortgage Loan and (ii) 100% of the
                        insurable replacement cost of the improvements located
                        on the related Mortgaged Property; the Mortgaged
                        Properties securing all of the Mortgage Loans having a
                        Stated Principal Balance in excess of $3,000,000 have,
                        as of the date hereof, insurance policies in place with
                        respect to acts of terrorism or damage related thereto
                        (excluding acts involving nuclear, biological or
                        chemical terrorism), except any such Mortgage Loans that
                        are listed on the applicable Exception Report. All
                        premiums on such insurance policies required to be paid
                        as of the date hereof have been paid; such insurance
                        policies or the related insurance certificates require
                        prior notice to the insured of reduction in coverage,
                        termination or cancellation, and no such notice has been
                        received by the Seller; such insurance names the lender
                        under the Mortgage Loan and its successors and assigns
                        as a named or additional insured; each related Mortgage
                        Loan obligates the related borrower to maintain all such
                        insurance and, at such borrower's failure to do so,
                        authorizes the lender to maintain such insurance at the
                        borrower's cost and expense and to seek reimbursement
                        therefor from such borrower;

                              (xxiv) There is no monetary default, breach,
                        violation or event of acceleration existing under the
                        related Mortgage Loan. To the Seller's knowledge, there
                        is no (a) non-monetary default, breach, violation or
                        event of acceleration existing under the related
                        Mortgage Loan or (b) event (other than payments due but
                        not yet delinquent) which, with the passage of time or
                        with notice and the expiration of any grace or cure
                        period, would constitute a default, breach, violation or
                        event of acceleration, which default, breach, violation
                        or event of acceleration, in the case of either (a) or
                        (b) would materially and adversely affect the use or
                        value of the Mortgage Loan or the related Mortgaged
                        Property; provided, however, that this representation
                        and warranty does not address or otherwise cover any
                        default, breach, violation or event of acceleration that
                        specifically pertains to any matter otherwise covered by
                        any other representation or warranty made by the Seller
                        in any of paragraphs (xiii), (xxi), (xxv), (xxvii),
                        (xxix), and (xxxi) of this Exhibit A-1;

                              (xxv) No Mortgage Loan has been more than 30 days
                        delinquent in making required payments since origination
                        and as of the Cut-off Date no Mortgage Loan is 30 or
                        more days delinquent in making required payments;

                              (xxvi) (a) Each related Mortgage contains
                        provisions so as to render the rights and remedies of
                        the holder thereof adequate for the practical
                        realization against the Mortgaged Property of the
                        principal benefits of the security, including
                        realization by judicial or, if applicable, non-judicial
                        foreclosure or, subject to applicable state law
                        requirements, appointment of a receiver, and (b) there
                        is no exemption available to the borrower which would
                        interfere with such right to foreclose, except, in the
                        case of either (a) or (b), as the enforcement of the
                        Mortgage may be limited by bankruptcy, insolvency,
                        reorganization, moratorium, redemption or other laws
                        affecting the enforcement of creditors' rights or by
                        general principles of equity (regardless of whether such
                        enforceability is considered in a proceeding in equity
                        or at law). No borrower is a debtor in a state or
                        federal bankruptcy or insolvency proceeding;

                              (xxvii) At origination, each borrower represented
                        and warranted in all material respects that to its
                        knowledge, except as set forth in certain environmental
                        reports and, except as commonly used in the operation
                        and maintenance of properties of similar kind and nature
                        to the Mortgaged Property, in accordance with prudent
                        management practices and applicable law, and in a manner
                        that does not result in any contamination of the
                        Mortgaged Property, it has not used, caused or permitted
                        to exist and will not use, cause or permit to exist on
                        the related Mortgaged Property any hazardous materials
                        in any manner which violates federal, state or local
                        laws, ordinances, regulations, orders, directives or
                        policies governing the use, storage, treatment,
                        transportation, manufacture, refinement, handling,
                        production or disposal of hazardous materials or other
                        environmental laws; the related borrower agreed to
                        indemnify, defend and hold the mortgagee and its
                        successors and assigns harmless from and against losses,
                        liabilities, damages, injuries, penalties, fines,
                        expenses, and claims of any kind whatsoever (including
                        attorneys' fees and costs) paid, incurred or suffered
                        by, or asserted against, any such party resulting from a
                        breach of the foregoing representations, warranties or
                        covenants given by the borrower in connection with such
                        Mortgage Loan. A Phase I environmental report and with
                        respect to certain Mortgage Loans, a Phase II

                        independent environmental consulting firm in connection
                        with such Mortgage Loan, which report did not indicate
                        any material non-compliance with applicable
                        environmental laws or material existence of hazardous
                        materials or, if any material non-compliance or material
                        existence of hazardous materials was indicated in any

                        statements is true: (A) funds reasonably estimated to be
                        sufficient to cover the cost to cure any material
                        non-compliance with applicable environmental laws or
                        material existence of hazardous materials have been
                        escrowed by the related borrower and held by the related
                        mortgagee; (B) if the environmental report recommended
                        an operations and maintenance plan, but not any material
                        expenditure of funds, an operations and maintenance plan
                        has been required to be obtained by the related
                        borrower; (C) the environmental condition identified in
                        the related environmental report was remediated or
                        abated in all material respects prior to the date
                        hereof; (D) a no further action or closure letter was
                        obtained from the applicable governmental regulatory
                        authority (or the environmental issue affecting the
                        related Mortgaged Property was otherwise listed by such
                        governmental authority as "closed"); (E) such conditions
                        or circumstances identified in the Phase I environmental
                        report were investigated further and based upon such
                        additional investigation, an environmental consultant
                        recommended no further investigation or remediation; (F)
                        a party unrelated to the borrower with financial
                        resources reasonably estimated to be adequate to cure
                        the condition or circumstance provided a guaranty or
                        indemnity to the related borrower to cover the costs of
                        any required investigation, testing, monitoring or
                        remediation; (G) the expenditure of funds reasonably
                        estimated to be necessary to effect such remediation is

                        lender's environmental insurance policy was obtained and
                        is a part of the related Mortgage File. Notwithstanding
                        the preceding sentence, with respect to certain Mortgage
                        Loans with an original principal balance of less than
                        $3,000,000, no environmental report may have been
                        obtained, but (in such cases where a Phase I
                        environmental report was not obtained) a lender's
                        secured creditor impairment environmental insurance
                        policy was obtained with respect to each such Mortgage
                        Loan. Each of such secured creditor impairment
                        environmental insurance policies is a part of the
                        related Mortgage File. Each of such environmental
                        insurance policies is in full force and effect, is in an
                        amount not less than the 100% of the balance of the
                        related Mortgage Loan, has a term extending not less

                        Mortgage Loan, the premiums for such policies have been
                        paid in full and the Trustee is named as an insured
                        under each of such policies, the Seller has delivered to
                        the insurer all environmental reports in its possession.
                        To the Seller's knowledge, in reliance on such
                        environmental reports and except as set forth in such
                        environmental reports, each Mortgaged Property is in
                        material compliance with all applicable federal, state
                        and local environmental laws, and to the Seller's
                        knowledge, no notice of violation of such laws has been
                        issued by any governmental agency or authority, except,
                        in all cases, as indicated in such environmental reports
                        or other documents previously provided to the Rating
                        Agencies; and the Seller has not taken any action which
                        would cause the Mortgaged Property to not be in
                        compliance with all federal, state and local
                        environmental laws pertaining to environmental hazards;

                        provisions for the acceleration of the payment of the
                        unpaid principal balance of such Mortgage Loan if,
                        without the consent of the holder of the Mortgage (and
                        the Mortgage requires the mortgagor to pay all fees and
                        expenses associated with obtaining such consent), the

                        estate planning related transfers that satisfy certain
                        criteria specified in the related Mortgage (which
                        criteria is consistent with the practices of prudent
                        commercial mortgage lenders) or any transfers in
                        connection with the death or disability of owners of the
                        borrower, each Mortgage Loan also contains the
                        provisions for the acceleration of the payment of the
                        unpaid principal balance of such Mortgage Loan if,
                        without the consent of the holder of the Mortgage, (and
                        the Mortgage requires the mortgagor to pay all fees and
                        expenses associated with obtaining such consent) a
                        majority interest in the related borrower is directly or
                        indirectly transferred or sold;

                        do not materially and adversely affect the use or value
                        of such Mortgaged Property. No improvements on adjoining
                        parcels encroach onto the related Mortgaged Property
                        except for encroachments that do not materially and
                        adversely affect the value of such Mortgaged Property,

                        of the Mortgaged Property, or the related borrower's
                        operations at the Mortgaged Property;

                              (xxx) The information pertaining to the Mortgage

                        leasehold estate of the related borrower, the related

                        default granted to such lessor under any agreement
                        binding upon the lender would not be considered

                        but for the passage of time or giving of notice, would
                        result in a default under the terms of such ground
                        lease;

                        located, or the failure to be so authorized did not
                        materially and adversely affect the enforceability of

                        underwriting requirements that would be customary for
                        prudent commercial mortgage lenders, which in all events
                        include payment of a release price at least 125% of the
                        appraised value of the property to be released or of the
                        allocated loan amount of such property or (c) releases

                        or partial release of any Mortgaged Property, or any
                        portion thereof, expressly permitted or required

                        the repair or restoration progresses (except in any case
                        where a provision entitling another party to hold and

                        commercial lease either by the lessee thereunder or by
                        the related borrower that could give rise to the

                        the extent the Seller is aware of such non-compliance,
                        it has required the related borrower to obtain law and
                        ordinance insurance coverage in amounts customarily
                        required by prudent commercial mortgage lenders;

                        withdrawal, downgrade or qualification of the then

                        related borrower is required to enter into a "lockbox
                        agreement" whereby all revenue from the related
                        Mortgaged Property shall be deposited directly into a
                        designated account controlled by the Master Servicer;

                        connection with its origination or acquisition of each
                        Mortgage Loan, the Seller obtained an appraisal of the
                        related Mortgaged Property, which appraisal is signed by
                        an appraiser, who, to the Seller's actual knowledge, had
                        no interest, direct or indirect, in the borrower, the
                        Mortgaged Property or in any loan made on the security
                        of the Mortgaged Property, and whose compensation was
                        not affected by the approval or disapproval of the
                        Mortgage Loan; and

                              (lix) Each Mortgage Loan bears interest at a rate
                        that remains fixed throughout the remaining term of such
                        Mortgage Loan, except in the case of an ARD Loan after
                        its Anticipated Repayment Date and except for the

      Notwithstanding the foregoing, in the event that, in connection with any

counterpart or certified copy of any of the documents required to be delivered
pursuant to clauses (b), (d), (h), (k) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement), (l) and (n) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement) above with evidence of recording or filing thereon on the
Closing Date, solely because of a delay caused by the public recording or filing
office where such document or instrument has been delivered for recordation or
filing, the Seller shall deliver, or cause to be delivered, to the Trustee or
its designee a duplicate original or true copy of such document certified by the
applicable public recording or filing office, the applicable title insurance
company or the Seller to be a true and complete duplicate original or copy of
the original thereof submitted for recording or filing.

      Notwithstanding the foregoing, in the event that, in connection with any
Mortgage Loan, the Seller cannot deliver, or cause to be delivered, an original,
counterpart or certified copy of any of the documents required to be delivered
pursuant to clauses (b), (d), (h), (k) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement), (l) and (n) (other than assignments of UCC financing
statements to be recorded or filed in accordance with the transfer contemplated
by this Agreement) above with evidence of recording or filing thereon, for any
other reason, including without limitation, that such non-delivered document has
been lost, the delivery requirements of this Agreement shall be deemed to have
been satisfied and such non-delivered document shall be deemed to have been
included in the related Mortgage File if a photocopy of such non-delivered
document (with evidence of recording or filing thereon and certified by the
appropriate recording or filing office to be a true and complete copy of the
original thereof as filed or recorded) is delivered to the Trustee or its
designee on or before the Closing Date.

      Notwithstanding the foregoing, in the event that the Seller cannot deliver
to the Trustee or its designee any UCC-2 or UCC-3 assignment with the filing
information of the UCC-1 financing statement with respect to any Mortgage Loan
being assigned, solely because such UCC-1 financing statement has not been
returned by the public filing office where such UCC-1 financing statement has
been delivered for filing, Seller shall deliver or cause to be delivered to the
Trustee or its designee a photocopy of such UCC-2 or UCC-3 assignment with the
filing information left blank. The Seller, promptly upon receipt of the
applicable filing information of the UCC-1 financing statement being so
assigned, shall deliver or cause to be delivered to the Trustee or its designee
the original UCC-2 or UCC-3 assignment with all appropriate filing information
set forth thereon.

      Notwithstanding the foregoing, Seller may, at its sole cost and expense,
engage a third party contractor to prepare or complete in proper form for filing
or recording any and all assignments of Mortgage, assignments of Assignments of
Leases and assignments of UCC financing statements to the Trustee to be
delivered pursuant to clauses (c), (e), (k) and (n) above (collectively, the
"Assignments"), to submit the Assignments for filing and recording, as the case
may be, in the applicable public filing and recording offices and to deliver the
Assignments to the Trustee or its designee as the Assignments (or certified
copies thereof) are received from the applicable filing and recording offices
with evidence of such filing or recording indicated thereon. However, in the
event the Seller engages a third party contractor as contemplated in the
immediately preceding sentence, the rights, duties and obligations of the Seller
pursuant to this Agreement remain binding on the Seller.

      Within ten (10) Business Days after the Closing Date, the Seller shall
deliver the Servicer Files with respect to each of the Mortgage Loans to the
Master Servicer under the Pooling and Servicing Agreement on behalf of the
Trustee in trust for the benefit of the Certificateholders. Each such Servicer
File shall contain all documents and records in the Seller's possession relating
to such applicable Mortgage Loans (including reserve and escrow agreements, cash
management agreements, lockbox agreements, financial statements and any other
information provided by the respective Borrower from time to time, but excluding
any documents and other writings not enumerated in this parenthetical that have
been prepared by the Seller or any of its Affiliates solely for internal
communication) that are not required to be a part of a Mortgage File in
accordance with the definition thereof, together with copies of all instruments
and documents which are required to be a part of the related Mortgage File in
accordance with the definition thereof.

      For purposes of this Section 3, and notwithstanding any contrary provision
hereof or of the definition of "Mortgage File", if there exists with respect to
any group of Crossed Loans only one original or certified copy of any document
or instrument described in the definition of "Mortgage File" which pertains to
all of the Crossed Loans in such group of Crossed Loans, the inclusion of the
original or certified copy of such document or instrument in the Mortgage File
for any of such Crossed Loans and the inclusion of a copy of such original or
certified copy in each of the Mortgage Files for the other Crossed Loans in such
group of Crossed Loans, shall be deemed the inclusion of such original or
certified copy, as the case may be, in the Mortgage File for each such Crossed
Loan.

      The Trustee, as assignee or transferee of Depositor, shall be entitled to
all scheduled principal payments due after the Cut-off Date, all other payments
of principal due and collected after the Cut-off Date, and all payments of
interest on the Mortgage Loans, minus that portion of any such payment which is
allocable to the period on or prior to the Cut-off Date. All scheduled payments
of principal due on or before the Cut-off Date and collected after the Cut-off
Date, together with the accompanying interest payments, shall belong to Seller.

      Upon the sale of the Mortgage Loans from Seller to Depositor pursuant
hereto, the ownership of each Note, the related Mortgage and the contents of the
related Mortgage File shall be vested in Depositor and the ownership of all
records and documents with respect to the related Mortgage Loan prepared by or
which come into the possession of Seller as seller of the Mortgage Loans
hereunder, exclusive in each case of documents prepared by Seller or any of its
Affiliates solely for internal uses, shall immediately vest in Depositor. All
Monthly Payments, Principal Prepayments and other amounts received by Seller and
not otherwise belonging to Seller pursuant to this Agreement shall be sent by
Seller within three (3) Business Days after Seller's receipt thereof to the
Master Servicer via wire transfer for deposit by the Master Servicer into the
Collection Account.

required;

            (v) such other certificates of Seller's officers or others and such
      other documents to evidence fulfillment of the conditions set forth in
      this Agreement as Depositor or its counsel may reasonably request; and

            (vi) all other information, documents, certificates, or letters with

Depositor.

      (b) Seller shall have received all of the following closing documents, in
such forms as are agreed upon and reasonably acceptable to Seller and Depositor,

      Section 6. Representations and Warranties of Seller.

      (a) Seller represents and warrants to Depositor as of the date hereof, as
follows:

            (i) Seller is duly organized and is validly existing as a national
      banking association in good standing under the laws of the United States
      of America. Seller has conducted and is conducting its business so as to
      comply in all material respects with all applicable statutes and
      regulations of regulatory bodies or agencies having jurisdiction over it,
      except where the failure so to comply would not have a materially adverse
      effect on the performance by Seller of this Agreement, and there is no
      charge, action, suit or proceeding before or by any court, regulatory
      authority or governmental agency or body pending or, to the knowledge of
      Seller, threatened, which is reasonably likely to materially and adversely
      affect the performance by Seller of this Agreement or the consummation of
      transactions contemplated by this Agreement.

            (ii) Seller has the full power, authority and legal right to hold,
      transfer and convey the Mortgage Loans and to execute and deliver this
      Agreement (and all agreements and documents executed and delivered by
      Seller in connection herewith) and to perform all transactions of Seller
      contemplated by this Agreement (and all agreements and documents executed
      and delivered by Seller in connection herewith). Seller has duly
      authorized the execution, delivery and performance of this Agreement (and
      all agreements and documents executed and delivered by Seller in
      connection herewith), and has duly executed and delivered this Agreement
      (and all agreements and documents executed and delivered by Seller in
      connection herewith). This Agreement (and each agreement and document
      executed and delivered by Seller in connection herewith), assuming due
      authorization, execution and delivery thereof by each other party thereto,
      constitutes the legal, valid and binding obligation of Seller enforceable
      in accordance with its terms, except as such enforcement may be limited by
      bankruptcy, fraudulent transfer, insolvency, reorganization, receivership,
      moratorium or other laws relating to or affecting the rights of creditors
      generally, by general principles of equity (regardless of whether such
      enforcement is considered in a proceeding in equity or at law) and by
      considerations of public policy.

            (iii) Neither the execution, delivery and performance of this
      Agreement, nor the fulfillment of or compliance with the terms and
      conditions of this Agreement by Seller, will (a) conflict with or result
      in a breach of any of the terms, conditions or provisions of Seller's
      articles of association, as amended, or other organizational documents;
      (b) conflict with, result in a breach of, or constitute a default or
      result in an acceleration under, any agreement or instrument to which
      Seller is now a party or by which it (or any of its properties) is bound
      if compliance therewith is necessary (1) to ensure the enforceability of
      this Agreement or (2) for Seller to perform its duties and obligations
      under this Agreement (or any agreement or document executed and delivered
      by Seller in connection herewith); (c) conflict with or result in a breach
      of any legal restriction if compliance therewith is necessary (1) to
      ensure the enforceability of this Agreement or (2) for Seller to perform
      its duties and obligations under this Agreement (or any agreement or
      document executed and delivered by Seller in connection herewith); (d)
      result in the violation of any law, rule, regulation, order, judgment or
      decree to which Seller or its property is subject if compliance therewith
      is necessary (1) to ensure the enforceability of this Agreement or (2) for
      Seller to perform its duties and obligations under this Agreement (or any
      agreement or document executed and delivered by Seller in connection
      herewith); or (e) result in the creation or imposition of any lien, charge
      or encumbrance that would have a material adverse effect upon Seller's
      ability to perform its duties and obligations under this Agreement (or any
      agreement or document executed and delivered by Seller in connection
      herewith), or materially impair the ability of the Depositor to realize on
      the Mortgage Loans.

            (iv) Seller is solvent and the sale of Mortgage Loans (1) will not
      cause Seller to become insolvent and (2) is not intended by Seller to
      hinder, delay or defraud any of its creditors.

            (v) No consent, approval, authorization or order of, or registration
      or filing with, or notice to, any court or governmental agency or body
      having jurisdiction or regulatory authority over Seller is required for
      (a) Seller's execution, delivery and performance of this Agreement (and
      each agreement and document executed and delivered by Seller in connection
      herewith), (b) Seller's transfer and assignment of the Mortgage Loans, or
      (c) the consummation by Seller of the transactions contemplated by this
      Agreement (and each agreement and document executed and delivered by
      Seller in connection herewith) or, to the extent so required, such
      consent, approval, authorization, order, registration, filing or notice
      has been obtained, made or given (as applicable), except that Seller may
      not be duly qualified to transact business as a foreign corporation or
      licensed in one or more states if such qualification or licensing is not
      necessary to ensure the enforceability of this Agreement (or any agreement
      or document executed and delivered by Seller in connection herewith).

            (vi) The consideration received by Seller upon the sale of the
      Mortgage Loans constitutes fair consideration and reasonably equivalent
      value for such Mortgage Loans.

            (vii) Seller does not believe, nor does it have any reason or cause
      to believe, that it cannot perform each and every covenant of Seller
      contained in this Agreement (or any agreement or document executed and
      delivered by Seller in connection herewith).

            (viii) There are no actions, suits proceedings pending or to
      Seller's knowledge threatened in writing against Seller which are
      reasonably likely to draw into question the validity of this Agreement (or
      any agreement or document executed and delivered by Seller in connection
      herewith) or which, either in any one instance or in the aggregate, are
      reasonably likely to materially impair the ability of Seller to perform
      its duties and obligations under this Agreement (or any agreement or
      document executed and delivered by Seller in connection herewith).

            (ix) Seller's performance of its duties and obligations under this
      Agreement (and each agreement or document executed and delivered by Seller
      in connection herewith) is in the ordinary course of business of Seller
      and Seller's transfer, assignment and conveyance of the Mortgage Loans
      pursuant to this Agreement are not subject to the bulk transfer or similar
      statutory provisions in effect in any applicable jurisdiction.

            (x) Seller has not dealt with any Person that may be entitled, by
      reason of any act or omission of Seller, to any commission or compensation
      in connection with the sale of the Mortgage Loans to the Depositor
      hereunder except for the reimbursement of expenses as described herein or
      otherwise in connection with the transactions described in Section 2 and
      the commissions or compensation owed to the Underwriters or the Initial
      Purchaser.

            (xi) Seller is not in default or breach of any agreement or
      instrument to which Seller is now a party or by which it (or any of its
      properties) is bound which breach or default would materially and
      adversely affect the ability of Seller to perform its obligations under
      this Agreement.

            (xii) The representations and warranties contained in Exhibit A and
      the exceptions to such representations and warranties set forth on
      Schedule V hereto are true and correct in all material respects as of the
      date hereof with respect to the Mortgage Loans.

      Section 7. Obligations of Seller. Each of the representations and
warranties contained in or required to be made by Seller pursuant to Section 6
of this Agreement shall survive the sale of the Mortgage Loans and shall
continue in full force and effect, notwithstanding any restrictive or qualified
endorsement on the Notes and notwithstanding subsequent termination of this
Agreement or the Pooling and Servicing Agreement. The representations and
warranties contained in or required to be made by Seller pursuant to Section 6
of this Agreement shall not be impaired by any review or examination of the
Mortgage Files or other documents evidencing or relating to the Mortgage Loans
or any failure on the part of Depositor to review or examine such documents and
shall inure to the benefit of the initial transferee of the Mortgage Loans from
Depositor including, without limitation, the Trustee for the benefit of the
Holders of the Certificates, notwithstanding (1) any restrictive or qualified
endorsement on any Note, assignment of Mortgage or reassignment of Assignment of
Leases or (2) any termination of this Agreement prior to the Closing but shall
not inure to the benefit of any subsequent transferee thereafter.

      If any Certificateholder, the Master Servicer, the Special Servicer or the
Trustee discovers or receives notice: of a breach of any of the representations
or warranties made by the Seller with respect to the Mortgage Loans (subject to
the exceptions to such representations and warranties set forth in the Exception
Report), as of the date hereof in Section 6(a)(xii) or as of the Closing Date
pursuant to Section 4(b)(iii) (a "Breach"); or that (a) any document required to
be included in the Mortgage File related to any Mortgage Loan is not in the
Trustee's (or its designee's) possession within the time period required herein
or (b) such document has not been properly executed or is otherwise defective on
its face (clause (a) and clause (b) each, a "Defect" (including the "Defects"
described below) in the related Mortgage File), such party shall give notice to
the Master Servicer, the Special Servicer, the Trustee and the Rating Agencies.
If the Master Servicer or the Special Servicer determines that such Breach or
Defect materially and adversely affects the value of any Mortgage Loan or REO
Loan or the interests of the Holders of any Class of Certificates, it shall give
prompt written notice of such Breach or Defect to the Depositor, the Trustee,
the Master Servicer, the Special Servicer and the Seller and shall request that
the Seller not later than the earlier of 90 days from the receipt by the Seller
of such notice or discovery by the Seller of such Breach or Defect (subject to
the second succeeding paragraph, the "Initial Resolution Period"), (i) cure such
Breach or Defect in all material respects; (ii) repurchase the affected Mortgage
Loan at the applicable Purchase Price (as defined in the Pooling and Servicing
Agreement) or (iii) substitute one or more Qualified Substitute Mortgage Loans
(as defined in the Pooling and Servicing Agreement) for such affected Mortgage
Loan (provided that in no event shall any substitution occur later than the
second anniversary of the Closing Date) and pay the Master Servicer for deposit
into the Collection Account any Substitution Shortfall Amount (as defined in the
Pooling and Servicing Agreement) in connection therewith; provided, however,
that if (i) such material Breach or material Defect is capable of being cured
but not within the Initial Resolution Period, (ii) such material Breach or
material Defect does not cause the related Mortgage Loan not to be a "qualified
mortgage" (within the meaning of Section 860G(a)(3) of the Code), (iii) the
Seller has commenced and is diligently proceeding with the cure of such material
Breach or material Defect within the Initial Resolution Period and (iv) the
Seller has delivered to the Rating Agencies and the Trustee an Officer's
Certificate that describes the reasons that the cure was not effected within the
Initial Resolution Period and the actions that it proposes to take to effect the
cure and that states that it anticipates the cure will be effected within the
additional 90-day period, then the Seller shall have an additional 90 days to
cure such material Defect or material Breach. If any Breach pertains to a
representation or warranty that the related 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 Seller shall cure such Breach within the
Initial Resolution Period by reimbursing the Trust Fund (by wire transfer of
immediately available funds) the reasonable amount of any such costs and
expenses incurred by the Master Servicer, the Special Servicer, the Trustee or
the Trust Fund 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 Seller shall have the option to either repurchase
the related Mortgage Loan at the applicable Purchase Price or pay such costs and
expenses. Except as provided in the proviso to the immediately preceding
sentence, the Seller shall remit the amount of such costs and expenses and upon
its making such remittance, the Seller shall be deemed to have cured such Breach
in all respects. With respect to any substitution of one or more Qualified
Substitute Mortgage Loans for a Mortgage Loan hereunder, (A) no such
substitution may be made in any calendar month after the Determination Date for
such month; (B) scheduled payments of principal and interest due with respect to
the Qualified Substitute Mortgage Loan(s) after the related date of substitution
shall be part of the Trust Fund; and (C) scheduled payments of principal and
interest due with respect to such Qualified Substitute Mortgage Loan(s) on or
prior to the related date of substitution shall not be part of the Trust Fund,
and the Seller shall be entitled to receive such payments promptly following
receipt by the Master Servicer or Special Servicer, as applicable, under the
Pooling and Servicing Agreement.

      Any of the following will cause a document in the Mortgage File to be
deemed to have a "Defect" and to be conclusively presumed to materially and
adversely affect the interests of the Holders of a Class of Certificates and the
value of a Mortgage Loan or REO Loan: (a) the absence from the Mortgage File of
the original signed Note, unless the Mortgage File contains a signed lost note
affidavit and indemnity; (b) the absence from the Mortgage File of the original
signed Mortgage, unless there is included in the Mortgage File a certified copy
of the Mortgage as recorded or as sent for recordation, together with a
certificate stating that the original signed Mortgage was sent for recordation,
or a copy of the Mortgage and the related recording information; (c) the absence
from the Mortgage File of the item called for by paragraph (i) of the definition
of Mortgage File; (d) the absence from the Mortgage File of any intervening
assignments required to create an effective assignment to the Trustee on behalf
of the Trust, unless there is included in the Mortgage File a certified copy of
the intervening assignment and a certificate stating that the original
intervening assignments were sent for recordation; or (e) the absence from the
Servicer File of any required original letter of credit (as required in the
provisos to Section 1 hereof), provided that such Defect may be cured by any
substitute letter of credit or cash reserve or (f) the absence from the Mortgage
File of an original or copy of any required ground lease. In addition, the
Seller shall cure any Defect described in clause (b), (c), (e) or (f) of the
immediately preceding sentence as required in Section 2.02(b) of the Pooling and
Servicing Agreement.

      Any Defect or Breach which causes any Mortgage Loan not to be a "qualified
mortgage" (within the meaning of Section 860G(a)(3) of the Code) shall be deemed
to materially and adversely affect the interests of the Holders of a Class of
Certificates therein and the Initial Resolution Period for the affected Mortgage
Loan shall be 90 days following the earlier of the Seller's receipt of notice
pursuant to this Section 7 or its discovery of such Defect or Breach (which
period shall not be subject to extension).

      If the Seller does not, as required by this Section 7, correct or cure a
material Breach or a material Defect in all material respects within the
applicable Initial Resolution Period (as extended pursuant to this Section 7),
or if such Breach or Defect is not capable of being so corrected or cured with
such period, then the Seller shall purchase or substitute for the affected
Mortgage Loan as provided in this Section 7. If (i) any Mortgage Loan is
required to be repurchased or substituted for as provided above, (ii) such
Mortgage Loan is a Crossed Loan that is a part of a Mortgage Group (as defined
below) and (iii) the applicable Breach or Defect does not constitute a Breach or
Defect, as the case may be, as to any other Crossed Loan in such Mortgage Group
(without regard to this paragraph), then the applicable Breach or Defect, as the
case may be, will be deemed to constitute a Breach or Defect, as the case may
be, as to any other Crossed Loan in the Mortgage Group for purposes of the above
provisions, and the Seller will be required to repurchase or substitute for such
other Crossed Loan(s) in the related Mortgage Group in accordance with the
provisions of this Section 7 unless such other Crossed Loans satisfy the Crossed
Loan Repurchase Criteria (as defined in the Pooling and Servicing Agreement) and
the Seller can satisfy all other criteria for substitution or repurchase of the
affected Mortgage Loan set forth in the Pooling and Servicing Agreement. In the
event that one or more of such other Crossed Loans satisfy the Crossed Loan
Repurchase Criteria, the Seller may elect either to repurchase or substitute for
only the affected Crossed Loan as to which the related Breach or Defect exists
or to repurchase or substitute for all of the Crossed Loans in the related
Mortgage Group. The Seller shall be responsible for the cost of any Appraisal
required to be obtained by the Master Servicer to determine if the Crossed Loan
Repurchase Criteria have been satisfied, so long as the scope and cost of such
Appraisal has been approved by the Seller (such approval not to be unreasonably
withheld). For purposes of this paragraph, a "Mortgage Group" is any group of
Mortgage Loans identified as a Mortgage Group on Schedule III to this Agreement.

      Notwithstanding the foregoing, if there is a material Breach or material
Defect with respect to one or more Mortgaged Properties (but not all of the
Mortgaged Properties) with respect to a Mortgage Loan, the Seller will not be
obligated to repurchase or substitute for the Mortgage Loan if the affected
Mortgaged Property may be released pursuant to the terms of any partial release
provisions in the related Mortgage Loan Documents and the remaining Mortgaged
Property(ies) satisfy the requirements, if any, set forth in the Mortgage Loan
Documents and (i) the Seller provides an opinion of counsel to the effect that
such partial release would not cause an Adverse REMIC Event (as defined in the
Pooling and Servicing Agreement) to occur, (ii) such Seller pays (or causes to
be paid) the applicable release price required under the Mortgage Loan
Documents, and to the extent not reimbursable out of the release price pursuant
to the related Mortgage Loan Documents, together with any additional amounts
necessary to cover all reasonable out-of-pocket expenses reasonably incurred by
the Master Servicer, the Special Servicer, the Trustee or the Trust Fund in
connection therewith, including any unreimbursed advances and interest thereon
made with respect to the Mortgaged Property which is being released and (iii)
such cure by release of such Mortgaged Property is effected within the time
periods specified for cure of a material Breach or material Defect in this
Section 7.

      The Purchase Price or Substitution Shortfall Amount for any repurchased or
substituted Mortgage Loan shall be payable to the Depositor or, subsequent to
the assignment of the Mortgage Loans to the Trustee, the Trustee as its
assignee, by wire transfer of immediately available funds to the account
designated by the Depositor or the Trustee, as the case may be, and the
Depositor or the Trustee, as the case may be, upon receipt of such funds, shall
promptly release the related Mortgage File and Servicer File or cause them to be
released, to Seller and shall execute and deliver such instruments of transfer
or assignment as shall be necessary to vest in the Seller the legal and
beneficial ownership of such Mortgage Loan (including any property acquired in
respect thereof or proceeds of any insurance policy with respect thereto) and
the related Mortgage Loan Documents.

      It is understood and agreed that the obligations of the Seller set forth
in this Section 7 to cure, substitute for or repurchase a Mortgage Loan
constitute the sole remedies available to the Depositor and its successors and
assigns respecting any Breach or Defect affecting such Mortgage Loan.

      Section 8. Crossed Loans. With respect to any Crossed Loan conveyed
hereunder, to the extent that the Seller repurchases or substitutes for an
affected Crossed Loan in the manner prescribed above while the Trustee continues
to hold any related Crossed Loans, the Seller and the Depositor (on behalf of
its successors and assigns) agree to modify upon such repurchase or
substitution, the related Mortgage Loan Documents in a manner such that such
affected Crossed Loan repurchased or substituted by the Seller, on the one hand,
and any related Crossed Loans still held by the Trustee, on the other, would no
longer be cross-defaulted or cross-collateralized with one another; provided,
that the Seller shall have furnished to the Trustee, at its expense, with an
Opinion of Counsel that such modification shall not cause an Adverse REMIC
Event; provided, further, that if such Opinion of Counsel cannot be furnished,
the Seller and the Depositor hereby agree that such repurchase or substitution
of only the affected Crossed Loans, notwithstanding anything to the contrary
herein, shall not be permitted. Any reserve or other cash collateral or letters
of credit securing the Crossed Loans shall be allocated between such Mortgage
Loans in accordance with the Mortgage Loan Documents. All other terms of the
Mortgage Loans shall remain in full force and effect, without any modification
thereof.

      Section 9. [Reserved]

      Section 10. Representations and Warranties of Depositor. Depositor hereby
represents and warrants to Seller as of the date hereof, as follows:

power and authority to own its assets and conduct its business as it is
conducted, and is duly qualified as a foreign corporation in good standing in

transactions contemplated by this Agreement).

      (b) The execution and delivery by Depositor of this Agreement and the
performance of Depositor's obligations hereunder are within the corporate power
of Depositor and have been duly authorized by Depositor and neither the
execution and delivery by Depositor of this Agreement nor the compliance by
Depositor with the provisions hereof, nor the consummation by Depositor of the
transactions contemplated by this Agreement, will (i) conflict with or result in
a breach of, or constitute a default under, the certificate of incorporation or
by-laws of Depositor or, after giving effect to the consents or taking of the
actions contemplated by clause (ii) of this paragraph (b), any of the provisions
of any law, governmental rule, regulation, judgment, decree or order binding on
Depositor or its properties, or any of the provisions of any material indenture
or mortgage or any other material contract or other instrument to which
Depositor is a party or by which it is bound or result in the creation or
imposition of any lien, charge or encumbrance upon any of its properties
pursuant to the terms of any such indenture, mortgage, contract or other
instrument or (ii) require the consent of or notice to, or any filing with any
person, entity or governmental body, which has not been obtained or made by
Depositor, except where, in any of the instances contemplated by clause (i)
above or this clause (ii), the failure to do so will not have a material and
adverse effect on the consummation of any transactions contemplated by this
Agreement.

      (c) This Agreement has been duly executed and delivered by Depositor and
this Agreement constitutes a legal, valid and binding instrument, enforceable
against Depositor in accordance with its terms, subject, as to the enforcement
of remedies, to applicable bankruptcy, reorganization, insolvency, moratorium
and other laws affecting the rights of creditors generally and to general
principles of equity and the discretion of the court (regardless of whether
enforcement of such remedies is considered in a proceeding in equity or at law)
and, as to rights of indemnification hereunder, subject to limitations of public
policy under applicable securities laws.

      (d) There is no litigation, charge, investigation, action, suit or
proceeding by or before any court, regulatory authority or governmental agency
or body pending or, to the knowledge of Depositor, threatened against Depositor
the outcome of which could be reasonably expected to materially and adversely
affect the consummation of any transactions contemplated by this Agreement.

      Section 11. Survival of Certain Representations, Warranties and Covenants.
The respective representations and warranties set forth in or made pursuant to
this Agreement, and the respective obligations of the parties hereto under
Sections 7 and 11 of this Agreement, will remain in full force and effect,
regardless of any investigation or statement as to the result thereof made by or
on behalf of any party and will survive payment for the various transfers
referred to herein and delivery of the Certificates or termination of this
Agreement.

      Section 12. [Reserved]

      Section 13. Expenses; Recording Costs. Seller agrees to reimburse the
Trustee or its designee all recording and filing fees incurred by the Trustee or
its designee in connection with the recording or filing of the Mortgage Loan
Documents listed in Section 3 of this Agreement. In the event Seller elects to
engage a third party contractor to prepare, complete, file and record
Assignments with respect to Mortgage Loans as provided in Section 3, Seller
shall contract directly with such contractor and shall be responsible for such
contractor's compensation and reimbursement of recording and filing fees and
other reimbursable expenses pursuant to their agreement.

prior to the Closing Date, will make the Mortgage Files available to Depositor
or its agent for examination during normal business hours at Seller's offices or
such other location as shall otherwise be agreed upon by Depositor and Seller.
The fact that Depositor or its agent has conducted or has failed to conduct any
partial or complete examination of the Mortgage Files shall not affect the
rights of Depositor or the Trustee (for the benefit of the Certificateholders)
to demand cure, repurchase, or other relief as provided herein.

      Section 16. Successors. This Agreement shall inure to the benefit of and
shall be binding upon Seller and Depositor and their respective successors,
permitted assigns and legal representatives, and nothing expressed in this
Agreement is intended or shall be construed to give any other Person any legal
or equitable right, remedy or claim under or in respect of this Agreement, or
any provisions herein contained, this Agreement and all conditions and
provisions hereof being intended to be and being for the sole and exclusive
benefit of such Persons and for the benefit of no other Person; it being
understood that (a) the indemnities of Seller contained in that certain
Indemnification Agreement dated July 18, 2002 among Seller, Depositor and the
Underwriters, subject to all limitations therein contained, shall also be for
the benefit of the officers and directors of Depositor, the Underwriters and the
Initial Purchaser and any person or persons who control Depositor, the
Underwriters and the Initial Purchaser within the meaning of Section 15 of the
Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended,
and (b) the rights of Depositor pursuant to this Agreement, subject to all
limitations herein contained, including those set forth in Section 7 of this
Agreement, may be assigned to the Trustee, for benefit of the
Certificateholders, as may be required to effect the purposes of the Pooling and
Servicing Agreement and, upon such assignment, the Trustee shall succeed to such
rights of Depositor hereunder, provided that the Trustee shall have no right to
further assign such rights to any other Person. No owner of a Certificate issued
pursuant to the Pooling and Servicing Agreement shall be deemed a successor or
permitted assign because of such ownership.

      Section 17. Governing Law. THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS TO
BE MADE AND PERFORMED ENTIRELY WITHIN SUCH STATE WITHOUT GIVING EFFECT TO CHOICE
OF LAW PRINCIPLES.

prohibited or invalid under applicable law, this Agreement shall be ineffective
only to such extent, without invalidating the remainder of this Agreement.

      Section 19. Further Assurances. Depositor and Seller agree to execute and
deliver such instruments and take such actions as the other parties may, from
time to time, reasonably request in order to effectuate the purpose and to carry
out the terms of this Agreement.

      Section 20. Counterparts. This Agreement may be executed in counterparts
(and by each of the parties hereto on different counterparts), each of which
when so executed and delivered will be an original, and all of which together
will be deemed to constitute but one and the same instrument.

      Section 21. Treatment as Security Agreement. It is the express intent of
the parties hereto that the conveyance of the Mortgage Loans by Seller to
Depositor as provided in this Agreement be, and be construed as, a sale of the
Mortgage Loans by Seller to Depositor. It is, further, not the intention of the
parties that such conveyance be deemed a pledge of the Mortgage Loans by Seller
to Depositor to secure a debt or other obligation of Seller. However, in the
event that, notwithstanding the intent of the parties, the Mortgage Loans are
held to be property of Seller or if for any reason this Agreement is held or
deemed to create a security interest in the Mortgage Loans:

      (a) this Agreement shall hereby create a security agreement within the
meaning of Articles 8 and 9 of the Uniform Commercial Code in effect in the
applicable state;

      (b) the conveyance provided for in this Agreement shall hereby grant from
Seller to Depositor a security interest in and to all of Seller's right, title,
and interest, whether now owned or hereafter acquired, in and to:

            (i) all accounts, contract rights (including any guarantees),
      general intangibles, chattel paper, instruments, documents, money, deposit
      accounts, certificates of deposit, goods, letters of credit, advices of
      credit and investment property consisting of, arising from or relating to
      any of the property described in the Mortgage Loans, including the related
      Notes, Mortgages and title, hazard and primary mortgage insurance policies
      identified on the Mortgage Loan Schedule, including all replacement
      Mortgage Loans, and all distributions with respect thereto payable after
      the Cut-off Date;

            (ii) all accounts, contract rights, general intangibles, chattel
      paper, instruments, documents, money, deposit accounts, certificates of
      deposit, goods, letters of credit, advices of credit and investment
      property arising from or by virtue of the disposition of, or collections
      with respect to, or insurance proceeds payable with respect to, or claims
      against other persons with respect to, all or any part of the collateral
      described in (i) above (including any accrued discount realized on
      liquidation of any investment purchased at a discount), in each case,
      payable after the Cut-off Date; and

            (iii) all cash and non-cash proceeds of the collateral described in
      (i) and (ii) above payable after the Cut-off Date;

      (c) the possession by Depositor or its assignee of the Notes and such
other goods, letters of credit, advices of credit, instruments, money,
documents, chattel paper or certificated securities shall be deemed to be
possession by the secured party or possession by a purchaser or a person
designated by him or her, for purposes of perfecting the security interest
pursuant to the Uniform Commercial Code (including, without limitation, Sections
9-306, 9-313 and 9-314 thereof) as in force in the relevant jurisdiction; and

      (d) notifications to persons holding such property, and acknowledgments,
receipts, confirmations from persons holding such property, shall be deemed to
be notifications to, or acknowledgments, receipts or confirmations from,
financial intermediaries, bailees or agents of, or persons holding for (as
applicable), Depositor or its assignee for the purpose of perfecting such
security interest under applicable law. The Seller at the direction of the
Depositor or its assignee, shall, to the extent consistent with this Agreement,
take such actions as may be necessary to ensure that, if this Agreement were
deemed to create a security interest in the Mortgage Loans and the proceeds
thereof, such security interest would be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of this Agreement. In connection herewith, Depositor and its assignee shall have
all of the rights and remedies of a secured party and creditor under the Uniform
Commercial Code as in force in the relevant jurisdiction.

      Section 22. Recordation of Agreement. To the extent permitted by
applicable law, this Agreement is subject to recordation following the Closing
Date in all appropriate public offices for real property records in all the
counties or other comparable jurisdictions in which any or all of the properties
subject to the Mortgages are situated, and in any other appropriate public
recording office or elsewhere, such recordation to be effected by Seller at
Seller's expense at the direction of Depositor accompanied by an Opinion of
Counsel to the effect that such recordation materially and beneficially affects
the interests of Depositor.

                    REPRESENTATIONS AND WARRANTIES OF SELLER
                          REGARDING THE MORTGAGE LOANS

            For purposes of these representations and warranties, the phrase "to
the knowledge of the Seller" or "to the Seller's knowledge" shall mean, except
where otherwise expressly set forth below, the actual state of knowledge of the
Seller or any servicer acting on its behalf regarding the matters referred to,
in each case without having conducted any independent inquiry or due diligence
with respect to such matters and without any actual or implied obligation to
make such inquiry or perform such due diligence, other than making such inquiry
or performing such due diligence as would be customarily performed by prudent
commercial or multifamily mortgage lenders or servicers (as the case may be)
with respect to similar mortgage loans or mortgaged properties. All information
contained in documents which are part of or required to be part of a Mortgage
File shall be deemed to be within the knowledge of the Seller. Wherever there is
a reference to receipt by, or possession of, the Seller of any information or
documents, or to any action taken by the Seller or not taken by the Seller, such
reference shall include the receipt or possession of such information or
documents by, or the taking of such action or the not taking of such action by,
either the Seller or any servicer acting on its behalf.

            The Seller hereby represents and warrants, subject to the exceptions
set forth in Schedule V, with respect to the Mortgage Loans that as of the date
hereinbelow specified or, if no such date is specified, as of the date of this
Agreement:

                  (i) Immediately prior to the sale, transfer and assignment to
            the Depositor, no Note or Mortgage was subject to any assignment
            (other than assignments which show a complete chain of assignment to
            the Seller), participation or pledge, and the Seller had good and
            marketable title to, and was the sole owner of, the related Mortgage
            Loan;

                  (ii) Each Mortgage Loan was either:

                        (A) originated by a savings and loan association,
                  savings bank, commercial bank, credit union, or insurance
                  company, which is supervised and examined by a Federal or
                  State authority, or by a mortgagee approved by the Secretary
                  of Housing and Urban Development pursuant to Sections 203 and
                  211 of the National Housing Act (any of the foregoing,
                  including the Seller, a "Qualified Originator"); or

                        (B) if originated by a person which is not a Qualified
                  Originator (any such person, a "Non-Qualified Originator"),
                  then:

                              (1) such Mortgage Loan was underwritten in
                        accordance with standards established by a Qualified
                        Originator, using application forms and related credit
                        documents approved by the Qualified Originator;

                              (2) the Qualified Originator approved each
                        application and related credit documents before a
                        commitment by the Non-Qualified Originator was issued,
                        and no such commitment was issued until the Qualified
                        Originator agreed to fund such Mortgage Loan;

                              (3) the Mortgage Loan was originated by the
                        Non-Qualified Originator pursuant to an ongoing,
                        standing relationship with the Qualified Originator; and

                              (4) the closing documents for the Mortgage Loan
                        were prepared on forms approved by the Qualified
                        Originator, and, pursuant to the Non-Qualified
                        Originator's ongoing, standing relationship with the
                        Qualified Originator, either:

                                    (a) such closing documents reflect the
                              Qualified Originator as the original mortgagee,
                              and such Mortgage Loan was actually funded by the
                              Qualified Originator at the closing thereof;

                                    (b) such closing documents reflect the
                              Non-Qualified Originator as the original
                              mortgagee, but include assignment documents
                              executed by the Non-Qualified Originator in favor
                              of the Qualified Originator at the time of the
                              closing of the Mortgage Loan, reflecting the
                              Qualified Originator as the successor and assign
                              to the Non-Qualified Originator, and the Mortgage
                              Loan was funded initially by the Non-Qualified
                              Originator at the closing thereof and then
                              acquired by the Qualified Originator from such
                              Non-Qualified Originator; or

                                    (c) such closing documents reflect the
                              Non-Qualified Originator as the original
                              mortgagee, but include assignment documents
                              executed by the Non-Qualified Originator in favor
                              of the Qualified Originator at the time of the
                              closing of the Mortgage Loan, reflecting the
                              Qualified Originator as the successor and assign
                              to the Non-Qualified Originator, and the Mortgage
                              Loan was funded initially by the Qualified
                              Originator at the closing thereof and then
                              acquired by the Qualified Originator from such
                              Non-Qualified Originator.

                  (iii) The Seller has full right and authority to sell, assign
            and transfer such Mortgage Loan and the assignment to the Depositor
            constitutes a legal, valid and binding assignment of such Mortgage
            Loan;

                  (iv) The Seller is transferring such Mortgage Loan free and
            clear of any and all liens, pledges, charges or any other interests
            or security interests of any nature encumbering such Mortgage Loan,
            except for interests in servicing rights created or granted under
            the Pooling and Servicing Agreement, subservicing agreements and/or
            servicing rights purchase agreements being executed and delivered in
            connection herewith;

                  (v) To Seller's knowledge, based on the related borrower's
            representations and covenants in the related mortgage loan documents
            and such other due diligence as a reasonably prudent commercial
            mortgage lender would deem appropriate, the borrower, lessee and/or
            operator was in possession of all licenses, permits, and
            authorizations then required for use of the Mortgaged Property which
            were valid and in full force and effect as of the origination date
            and to Seller's actual knowledge, such licenses, permits and
            authorizations are still valid and in full force and effect;

                  (vi) Each related Note, Mortgage, assignment of leases (if
            any) and other agreement executed by or for the benefit of the
            related borrower, any guarantor or their successors or assigns in
            connection with such Mortgage Loan is the legal, valid and binding
            obligation of the related borrower, enforceable in accordance with
            its terms, except as such enforcement may be limited by bankruptcy,
            insolvency, reorganization, moratorium or other laws affecting the
            enforcement of creditors' rights or by general principles of equity
            (regardless of whether such enforceability is considered in a
            proceeding in equity or at law); and there is no right of offset,
            rescission, abatement or diminution or valid defense or counterclaim
            available to the related borrower with respect to such Note,
            Mortgage, Assignment of Leases and other agreements, except as the
            enforcement thereof may be limited by bankruptcy, insolvency,
            reorganization, moratorium or other laws affecting the enforcement
            of creditors' rights or by general principles of equity (regardless
            of whether such enforceability is considered in a proceeding in
            equity or at law);

                  (vii) The Mortgage File contains an Assignment of Leases,
            either as a separate instrument or incorporated into the related
            Mortgage, which creates a valid first priority collateral assignment
            of, or a valid first priority lien or security interest in, certain
            rights under the related lease or leases, subject only to a license
            granted to the related borrower to exercise certain rights and to
            perform certain obligations of the lessor under such lease or
            leases, including the right to operate the related leased property,
            except as the enforcement thereof may be limited by bankruptcy,
            insolvency, reorganization, moratorium or other laws affecting the
            enforcement of creditors' rights or by general principles of equity
            (regardless of whether such enforceability is considered in a
            proceeding in equity or at law); no person other than the related
            borrower owns any interest in any payments due under such lease or
            leases that is superior to or of equal priority with the lender's
            interest therein;

                  (viii) Each related assignment of Mortgage from the Seller to
            the Depositor and related assignment of the Assignment of Leases, if
            the Assignment of Leases is a separate document from the Mortgage,
            is in recordable form, and such assignments and any assignment of
            any other agreement executed by or for the benefit of the related
            borrower, any guarantor or their successors or assigns in connection
            with such Mortgage Loan from the Seller to the Depositor constitutes
            the legal, valid and binding assignment from the Seller to the
            Depositor, except as the enforcement thereof may be limited by
            bankruptcy, insolvency, reorganization, liquidation, receivership,
            moratorium or other laws relating to or affecting the enforcement of
            creditors' rights or by general principles of equity (regardless of
            whether such enforceability is considered in a proceeding in equity
            or at law);

                  (ix) Since origination (a) except as set forth in the related
            Mortgage File, such Mortgage Loan has not been modified, altered,
            satisfied, canceled, subordinated or rescinded in whole or in part
            and (b) each related Mortgaged Property has not been released, in
            whole or in part, from the lien of the related Mortgage in any
            manner which materially interferes with the security intended to be
            provided by such Mortgage and since May 10, 2002, no waiver,
            consent, modification, assumption, alteration, satisfaction,
            cancellation, subordination or rescission which changes the terms
            of, or the security for, the Mortgage Loan in any material respect
            has occurred or been given;

                  (x) Each related Mortgage is a valid and enforceable first
            lien on the related Mortgaged Property (subject to Permitted
            Encumbrances (as defined below)), except as the enforcement thereof
            may be limited by bankruptcy, insolvency, reorganization, moratorium
            or other laws affecting the enforcement of creditors' rights or by
            general principles of equity (regardless of whether such
            enforceability is considered in a proceeding in equity or at law);
            and such Mortgaged Property is free and clear of any mechanics' and
            materialmen's liens which are prior to or equal with the lien of the
            related Mortgage, except those which are insured against by a
            lender's title insurance policy (as described below). A UCC
            financing statement has been filed and/or recorded (or sent for
            filing or recording) in all places necessary to perfect a valid
            security interest in the personal property necessary to operate the
            Mortgaged Property as currently operated; and such security interest
            is a first priority security interest, subject to any prior purchase
            money security interest in such personal property, any personal
            property leases applicable to such personal property and any other
            security interest in such personal property which do not,
            individually or in the aggregate, materially interfere with the
            security intended to be provided for such Mortgage Loan. Any
            security agreement, chattel mortgage or equivalent document related
            to and delivered in connection with the Mortgage Loan establishes
            and creates a valid and enforceable lien on the property described
            therein, except as such enforcement may be limited by bankruptcy,
            insolvency, reorganization, moratorium or other laws affecting the
            enforcement of creditors' rights or by general principles of equity
            (regardless of whether such enforceability is considered in a
            proceeding in equity or at law). In the case of any Mortgage Loan
            secured by a hotel, the related loan documents contain such
            provisions as are necessary and UCC Financing Statements have been
            filed as necessary, in each case, to perfect a valid first priority
            security interest in the related operating revenues with respect to
            such Mortgaged Property. Notwithstanding the foregoing, no
            representation is made as to the perfection of any security interest
            in rent, operating revenues or other personal property to the extent
            that possession or control of such items or actions other than the
            filing of Uniform Commercial Code financing statements are required
            in order to effect such perfection;

                  (xi) The Seller has not taken any action that would cause the
            representations and warranties made by the related borrower in the
            related Mortgage Loan Documents not to be true;

                  (xii) The Seller has no knowledge that the material
            representations and warranties made by the related borrower in the
            related Mortgage Loan Documents are not true in any material
            respect;

                  (xiii) The lien of each related Mortgage is a first priority
            lien on the fee or leasehold interest of the related borrower in the
            principal amount of such Mortgage Loan or allocated loan amount of
            the portions of the Mortgaged Property covered thereby (as set forth
            in the related Mortgage) after all advances of principal and is
            insured by an ALTA lender's title insurance policy (except that if
            such policy is yet to be issued, such insurance may be evidenced by
            a "marked up" pro forma policy or title commitment in either case
            marked as binding and countersigned by the title company or its
            authorized agent, either on its face or by an acknowledged closing
            instruction or escrow letter), or its equivalent as adopted in the
            applicable jurisdiction, insuring the Seller and its successors and
            assigns (as sole insured) as to such lien, subject only to (a) the
            lien of current real property taxes, water charges, sewer rents and
            assessments not yet delinquent or accruing interest or penalties,
            (b) covenants, conditions and restrictions, rights of way, easements
            and other matters of public record, none of which, individually or
            in the aggregate, materially interferes with the current use of the
            Mortgaged Property or the security intended to be provided by such
            Mortgage or with the borrower's ability to pay its obligations when
            they become due or the value of the Mortgaged Property and (c) the
            exceptions (general and specific) and exclusions set forth in such
            policy, none of which, individually or in the aggregate, materially
            interferes with the current general use of the Mortgaged Property or
            materially interferes with the security intended to be provided by
            such Mortgage or with the related borrower's ability to pay its
            obligations when they become due or the value of the Mortgaged
            Property (items (a), (b) and (c) collectively, "Permitted
            Encumbrances") and with respect to each Mortgage Loan, such
            Permitted Encumbrances do not, individually or in the aggregate,
            materially interfere with the security intended to be provided by
            the related Mortgage, the current principal use of the related
            Mortgaged Property or the current ability of the related Mortgaged
            Property to generate income sufficient to service such Mortgage
            Loan; the premium for such policy was paid in full; such policy (or
            if it is yet to be issued, the coverage to be afforded thereby) is
            issued by a title insurance company licensed to issue policies in
            the state in which the related Mortgaged Property is located (unless
            such state is Iowa) and is assignable (with the related Mortgage
            Loan) to the Depositor and the Trustee without the consent of or any
            notification to the insurer, and is in full force and effect upon
            the consummation of the transactions contemplated by the Mortgage
            Loan Purchase Agreement; no claims have been made under such policy
            and the Seller has not undertaken any action or omitted to take any
            action, and has no knowledge of any such act or omission, which
            would impair or diminish the coverage of such policy;

                  (xiv) The proceeds of such Mortgage Loan have been fully
            disbursed and there is no requirement for future advances
            thereunder, and no future advances have been made which are not
            reflected in the related Mortgage File;

                  (xv) Except as set forth in a property inspection report or
            engineering report prepared in connection with the origination of
            the Mortgage Loan, as of the later of the date of origination of
            such Mortgage Loan or the most recent inspection of the related
            Mortgaged Property by the Seller, as applicable, and to the
            knowledge of Seller as of the date hereof, each related Mortgaged
            Property is free of any material damage that would affect materially
            and adversely the use or value of such Mortgaged Property as
            security for the Mortgage Loan (normal wear and tear excepted). If
            any of the inspection or engineering reports referred to above in
            this Paragraph (xv) revealed any immediate repair items, then one of
            the following is true: (a) the repairs and/or maintenance necessary
            to correct such condition have been completed in all material
            respects; (b) an escrow of funds is required or a letter of credit
            was obtained in an amount reasonably estimated to be sufficient to
            complete the repairs and/or maintenance necessary to correct such
            condition; or (c) the reasonable estimation at the time of
            origination of the Mortgage Loan of the cost to complete the repairs
            and/or maintenance necessary to correct such condition represented
            no more than the greater of (i) $50,000 and (ii) 2% of the value of
            the related Mortgaged Property as reflected in an appraisal
            conducted in connection with the origination of the subject Mortgage
            Loan; as of the closing date for each Mortgage Loan and, to the
            Seller's knowledge, as of the date hereof, there is no proceeding
            pending for the total or partial condemnation of such Mortgaged
            Property that would have a material adverse effect on the use or
            value of the Mortgaged Property;

                  (xvi) The Seller has inspected or caused to be inspected each
            related Mortgaged Property within the past twelve months, or the
            originator of the Mortgage Loan inspected or caused to be inspected
            each related Mortgaged Property within three months of origination
            of the Mortgage Loan;

                  (xvii) No Mortgage Loan has a shared appreciation feature, any
            other contingent interest feature or a negative amortization feature
            other than the ARD Loans which may have negative amortization from
            and after the Anticipated Repayment Date;

                  (xviii) Each Mortgage Loan is a whole loan and neither the
            Mortgage Loan nor the related Mortgage Loan Documents create or
            grant an equity participation to the Seller or any other party;

                  (xix) The Mortgage Rate (exclusive of any default interest,
            late charges, or prepayment premiums) of such Mortgage Loan complied
            as of the date of origination with, or was exempt from, applicable
            state or federal laws, regulations and other requirements pertaining
            to usury. Except to the extent any noncompliance did not materially
            and adversely affect the value of the related Mortgaged Property,
            the security provided by the Mortgage or the related borrower's
            operations at the related Mortgaged Property, any and all other
            requirements of any federal, state or local laws, including, without
            limitation, truth-in-lending, real estate settlement procedures,
            equal credit opportunity or disclosure laws, applicable to such
            Mortgage Loan have been complied with as of the date of origination
            of such Mortgage Loan;

                  (xx) Neither the Seller nor to the Seller's knowledge, any
            originator, committed any fraudulent acts during the origination
            process of any Mortgage Loan and the origination, servicing and
            collection of each Mortgage Loan is in all respects legal, proper
            and prudent in accordance with customary commercial mortgage lending
            standards, and no other person has been granted or conveyed the
            right to service the Mortgage Loans or receive any consideration in
            connection therewith, except as provided in the Pooling and
            Servicing Agreement or any permitted subservicing agreements;

                  (xxi) All taxes and governmental assessments that became due
            and owing prior to the date hereof with respect to each related
            Mortgaged Property and that are or may become a lien of priority
            equal to or higher than the lien of the related Mortgage have been
            paid or an escrow of funds has been established and such escrow
            (including all escrow payments required to be made prior to the
            delinquency of such taxes and assessments) is sufficient to cover
            the payment of such taxes and assessments;

                  (xxii) All escrow deposits and payments required pursuant to
            each Mortgage Loan are in the possession, or under the control, of
            the Seller or its agent and there are no deficiencies (subject to
            any applicable grace or cure periods) in connection therewith and
            all such escrows and deposits are being conveyed by the Seller to
            the Depositor and identified as such with appropriate detail, and
            with respect to any disbursements made from such escrows, any
            requirements for the disbursement of any such escrows have been
            complied with in all material respects;

                  (xxiii) Each related Mortgaged Property is insured by a fire
            and extended perils insurance policy, issued by an insurer meeting
            the requirements of the Pooling and Servicing Agreement, in an
            amount not less than the lesser of the principal amount of the
            related Mortgage Loan and the replacement cost (with no deduction
            for physical depreciation) and not less than the amount necessary to
            avoid the operation of any co-insurance provisions with respect to
            the related Mortgaged Property; each related Mortgaged Property is
            also covered by business interruption or rental loss insurance which
            covers a period of not less than 12 months and comprehensive general
            liability insurance in amounts generally required by prudent
            commercial mortgage lenders for similar properties; all Mortgaged
            Properties in California or in a seismic zone 4 or 5 have had a
            seismic assessment done and earthquake insurance was obtained to the
            extent any such Mortgaged Property has a probable maximum loss in
            the event of an earthquake of greater than twenty percent (20%) of
            the replacement value of the related improvements; if the Mortgaged
            Property for any Mortgage Loan is located within Florida or within
            25 miles of the coast of North Carolina, South Carolina, Georgia,
            Alabama, Mississippi, Louisiana or Texas, then, such Mortgaged
            Property is insured by windstorm insurance in an amount at least
            equal to the lesser of (i) the outstanding principal balance of such
            Mortgage Loan and (ii) 100% of the insurable replacement cost of the
            improvements located on the related Mortgaged Property; the
            Mortgaged Properties securing all of the Mortgage Loans having a
            Stated Principal Balance in excess of $3,000,000 have, as of the
            date hereof, insurance policies in place with respect to acts of
            terrorism or damage related thereto (excluding acts involving
            nuclear, biological or chemical terrorism), except any such Mortgage
            Loans that are listed on Schedule V hereto. All premiums on such
            insurance policies required to be paid as of the date hereof have
            been paid; such insurance policies or the related insurance
            certificates require prior notice to the insured of reduction in
            coverage, termination or cancellation, and no such notice has been
            received by the Seller; such insurance names the lender under the
            Mortgage Loan and its successors and assigns as a named or
            additional insured; each related Mortgage Loan obligates the related
            borrower to maintain all such insurance and, at such borrower's
            failure to do so, authorizes the lender to maintain such insurance
            at the borrower's cost and expense and to seek reimbursement
            therefor from such borrower;

                  (xxiv) There is no monetary default, breach, violation or
            event of acceleration existing under the related Mortgage Loan. To
            the Seller's knowledge, there is no (a) non-monetary default,
            breach, violation or event of acceleration existing under the
            related Mortgage Loan or (b) event (other than payments due but not
            yet delinquent) which, with the passage of time or with notice and
            the expiration of any grace or cure period, would constitute a
            default, breach, violation or event of acceleration, which default,
            breach, violation or event of acceleration, in the case of either
            (a) or (b) would materially and adversely affect the use or value of
            the Mortgage Loan or the related Mortgaged Property; provided,
            however, that this representation and warranty does not address or
            otherwise cover any default, breach, violation or event of
            acceleration that specifically pertains to any matter otherwise
            covered by any other representation or warranty made by the Seller
            in any of paragraphs (xiii), (xxi), (xxv), (xxvii), (xxix), and
            (xxxi) of this Exhibit A-1;

                  (xxv) No Mortgage Loan has been more than 30 days delinquent
            in making required payments since origination and as of the Cut-off
            Date no Mortgage Loan is 30 or more days delinquent in making
            required payments;

                  (xxvi) (a) Each related Mortgage contains provisions so as to
            render the rights and remedies of the holder thereof adequate for
            the practical realization against the Mortgaged Property of the
            principal benefits of the security, including realization by
            judicial or, if applicable, non-judicial foreclosure or, subject to
            applicable state law requirements, appointment of a receiver, and
            (b) there is no exemption available to the borrower which would
            interfere with such right to foreclose, except, in the case of
            either (a) or (b), as the enforcement of the Mortgage may be limited
            by bankruptcy, insolvency, reorganization, moratorium, redemption or
            other laws affecting the enforcement of creditors' rights or by
            general principles of equity (regardless of whether such
            enforceability is considered in a proceeding in equity or at law).
            No borrower is a debtor in a state or federal bankruptcy or
            insolvency proceeding;

                  (xxvii) At origination, each borrower represented and
            warranted in all material respects that to its knowledge, except as
            set forth in certain environmental reports and, except as commonly
            used in the operation and maintenance of properties of similar kind
            and nature to the Mortgaged Property, in accordance with prudent
            management practices and applicable law, and in a manner that does
            not result in any contamination of the Mortgaged Property, it has
            not used, caused or permitted to exist and will not use, cause or
            permit to exist on the related Mortgaged Property any hazardous
            materials in any manner which violates federal, state or local laws,
            ordinances, regulations, orders, directives or policies governing
            the use, storage, treatment, transportation, manufacture,
            refinement, handling, production or disposal of hazardous materials
            or other environmental laws; the related borrower agreed to
            indemnify, defend and hold the mortgagee and its successors and
            assigns harmless from and against losses, liabilities, damages,
            injuries, penalties, fines, expenses, and claims of any kind
            whatsoever (including attorneys' fees and costs) paid, incurred or
            suffered by, or asserted against, any such party resulting from a
            breach of the foregoing representations, warranties or covenants
            given by the borrower in connection with such Mortgage Loan. A Phase
            I environmental report and with respect to certain Mortgage Loans, a
            Phase II environmental report was conducted by a reputable
            independent environmental consulting firm in connection with such
            Mortgage Loan, which report did not indicate any material
            non-compliance with applicable environmental laws or material
            existence of hazardous materials or, if any material non-compliance
            or material existence of hazardous materials was indicated in any
            such report, then at least one of the following statements is true:
            (A) funds reasonably estimated to be sufficient to cover the cost to
            cure any material non-compliance with applicable environmental laws
            or material existence of hazardous materials have been escrowed by
            the related borrower and held by the related mortgagee; (B) if the
            environmental report recommended an operations and maintenance plan,
            but not any material expenditure of funds, an operations and
            maintenance plan has been required to be obtained by the related
            borrower; (C) the environmental condition identified in the related
            environmental report was remediated or abated in all material
            respects prior to the date hereof; (D) a no further action or
            closure letter was obtained from the applicable governmental
            regulatory authority (or the environmental issue affecting the
            related Mortgaged Property was otherwise listed by such governmental
            authority as "closed"); (E) such conditions or circumstances
            identified in the Phase I environmental report were investigated
            further and based upon such additional investigation, an
            environmental consultant recommended no further investigation or
            remediation; (F) a party unrelated to the borrower with financial
            resources reasonably estimated to be adequate to cure the condition
            or circumstance provided a guaranty or indemnity to the related
            borrower to cover the costs of any required investigation, testing,
            monitoring or remediation; (G) the expenditure of funds reasonably
            estimated to be necessary to effect such remediation is not greater
            than two percent (2%) of the outstanding principal balance of the
            related Mortgage Loan; or (H) a lender's environmental insurance
            policy was obtained and is a part of the related Mortgage File.
            Notwithstanding the preceding sentence, with respect to certain
            Mortgage Loans with an original principal balance of less than
            $3,000,000, no environmental report may have been obtained, but (in
            such cases where a Phase I environmental report was not obtained) a
            lender's secured creditor impairment environmental insurance policy
            was obtained with respect to each such Mortgage Loan and is a part
            of the related Mortgage File. Each of such environmental insurance
            policies is in full force and effect, is in an amount not less than
            the 100% of the balance of the related Mortgage Loan, has a term
            extending not less than 5 years after the maturity date of the
            related Mortgage Loan, the premiums for such policies have been paid
            in full and the Trustee is named as an insured under each of such
            policies, the Seller has delivered to the insurer all environmental
            reports in its possession. To the Seller's knowledge, in reliance on
            such environmental reports and except as set forth in such
            environmental reports, each Mortgaged Property is in material
            compliance with all applicable federal, state and local
            environmental laws, and to the Seller's knowledge, no notice of
            violation of such laws has been issued by any governmental agency or
            authority, except, in all cases, as indicated in such environmental
            reports or other documents previously provided to the Rating
            Agencies; and the Seller has not taken any action which would cause
            the Mortgaged Property to not be in compliance with all federal,
            state and local environmental laws pertaining to environmental
            hazards;

                  (xxviii) (1) Each Mortgage Loan contains provisions for the
            acceleration of the payment of the unpaid principal balance of such
            Mortgage Loan if, without the consent of the holder of the Mortgage
            (and the Mortgage requires the mortgagor to pay all fees and
            expenses associated with obtaining such consent), the related
            Mortgaged Property is directly or indirectly transferred or sold,
            and (2) except with respect to transfers of certain interests in the
            related borrower to persons already holding interests in the
            borrower, their family members, affiliated companies and other
            estate planning related transfers that satisfy certain criteria
            specified in the related Mortgage (which criteria is consistent with
            the practices of prudent commercial mortgage lenders) or any
            transfers in connection with the death or disability of owners of
            the borrower, each Mortgage Loan also contains the provisions for
            the acceleration of the payment of the unpaid principal balance of
            such Mortgage Loan if, without the consent of the holder of the
            Mortgage, (and the Mortgage requires the mortgagor to pay all fees
            and expenses associated with obtaining such consent) a majority
            interest in the related borrower is directly or indirectly
            transferred or sold;

                  (xxix) All improvements included in the related appraisal are
            within the boundaries of the related Mortgaged Property, except for
            encroachments onto adjoining parcels for which the Seller has
            obtained title insurance against losses arising therefrom or that do
            not materially and adversely affect the use or value of such
            Mortgaged Property. No improvements on adjoining parcels encroach
            onto the related Mortgaged Property except for encroachments that do
            not materially and adversely affect the value of such Mortgaged
            Property, the security provided by the Mortgage, the current use of
            the Mortgaged Property, or the related borrower's operations at the
            Mortgaged Property;

                  (xxx) The information pertaining to the Mortgage Loans which
            is set forth in the Mortgage Loan Schedule attached as an exhibit to
            this Mortgage Loan Purchase Agreement is complete and accurate in
            all material respects as of the dates of the information set forth
            therein (or, if not set forth therein, as of the Cut-Off Date);

                  (xxxi) If any Mortgage Loan is secured by the leasehold estate
            of the related borrower, the related Mortgage also encumbers the
            related lessor's fee interest in such Mortgaged Property;

                  (xxxii) With respect to any Mortgage Loan where all or a
            material portion of the estate of the related borrower therein is a
            leasehold estate, but the related Mortgage also encumbers the
            related lessor's fee interest in such Mortgaged Property: (a) such
            lien on the related fee interest is evidenced by the related
            Mortgage, (b) such Mortgage does not by its terms provide that it
            will be subordinated to the lien of any other mortgage or
            encumbrance upon such fee interest, (c) upon the occurrence of a
            default under the terms of such Mortgage by the related borrower,
            any right of the related lessor to receive notice of, and to cure,
            such default granted to such lessor under any agreement binding upon
            the Seller would not be considered commercially unreasonable in any
            material respect by prudent commercial mortgage lenders, (d) the
            related lessor has agreed in a writing included in the related
            Mortgage File that the related ground lease may not be amended or
            modified without the prior written consent of the lender and that
            any such action without such consent is not binding on the lender,
            its successors or assigns, and (e) the related ground lease is in
            full force and effect, and the Seller has no actual knowledge that
            any default beyond applicable notice and grace periods has occurred
            or that there is any existing condition which, but for the passage
            of time or giving of notice, would result in a default under the
            terms of such ground lease;

                  (xxxiii) With respect to Mortgage Loans that are
            cross-collateralized or cross-defaulted, all other loans that are
            cross-collateralized by or cross-defaulted with such Mortgage Loans
            are being transferred to the Depositor;

                  (xxxiv) Neither Seller nor any affiliate thereof has any
            obligation to make any capital contribution to any borrower under a
            Mortgage Loan, other than contributions made on or prior to the date
            hereof;

                  (xxxv) (1) The Mortgage Loan is directly secured by a Mortgage
            on a commercial property or multifamily residential property, and
            (2) the fair market value of such real property, as evidenced by an
            appraisal satisfying the requirements of FIRREA conducted within 12
            months of the origination of the Mortgage Loan, was at least equal
            to 80% of the principal amount of the Mortgage Loan (a) at
            origination (or if the Mortgage Loan has been modified in a manner
            that constituted a deemed exchange under Section 1001 of the Code at
            a time when the Mortgage Loan was not in default or default with
            respect thereto was not reasonably foreseeable, the date of the last
            such modification) or (b) at the date hereof; provided that the fair
            market value of the real property must first be reduced by (A) the
            amount of any lien on the real property interest that is senior to
            the Mortgage Loan and (B) a proportionate amount of any lien that is
            in parity with the Mortgage Loan (unless such other lien secures a
            Mortgage Loan that is cross-collateralized with such Mortgage Loan,
            in which event the computation described in (a) and (b) shall be
            made on an aggregated basis);

                  (xxxvi) There are no subordinate mortgages encumbering the
            related Mortgaged Property, nor are there any preferred equity
            interests held by the Seller or any mezzanine debt related to such
            Mortgaged Property, except as set forth in the Prospectus
            Supplement, this Exhibit A or in the Exception Report to this
            Mortgage Loan Purchase Agreement;

                  (xxxvii) The Mortgage Loan Documents executed in connection
            with each Mortgage Loan having an original principal balance in
            excess of $5,000,000 require that the related borrower be a
            single-purpose entity (for this purpose, "single-purpose entity"
            shall mean an entity, other than an individual, having
            organizational documents which provide substantially to the effect
            that it is formed or organized solely for the purpose of owning and
            operating one or more Mortgaged Properties, is prohibited from
            engaging in any business unrelated to such property and the related
            Mortgage Loan, does not have any assets other than those related to
            its interest in the related Mortgaged Property or its financing, or
            any indebtedness other than as permitted under the related Mortgage
            Loan). To the Seller's actual knowledge, each borrower has fully
            complied with the requirements of the related Mortgage Note and
            Mortgage and borrower's organizational documents regarding
            Single-Purpose Entity status;

                  (xxxviii) Each Mortgage Loan prohibits the related borrower
            from mortgaging or otherwise encumbering the Mortgaged Property, or
            any controlling equity interest in the borrower, without the prior
            written consent of the mortgagee or the satisfaction of debt service
            coverage or similar criteria specified in the Note or Mortgage which
            would be acceptable to a reasonably prudent commercial mortgage
            lender, and, except in connection with trade debt and equipment
            financings in the ordinary course of borrower's business, from
            carrying any additional indebtedness, except, in each case, liens
            contested in accordance with the terms of the Mortgage Loans or,
            with respect to each Mortgage Loan having an original principal
            balance of less than $4,000,000, any unsecured debt;

                  (xxxix) Each borrower covenants in the Mortgage Loan documents
            that it shall remain in material compliance with all material
            licenses, permits and other legal requirements necessary and
            required to conduct its business;

                  (xl) Each Mortgaged Property (a) is located on or adjacent to
            a dedicated road, or has access to an irrevocable easement
            permitting ingress and egress, (b) is served by public utilities and
            services generally available in the surrounding community or
            otherwise appropriate for the use in which the Mortgaged Property is
            currently being utilized, and (c) constitutes one or more separate
            tax parcels or is covered by an endorsement with respect to the
            matters described in (a), (b) or (c) under the related title
            insurance policy (or the binding commitment therefor);

                  (xli) Based solely on a flood zone certification or a survey
            of the related Mortgaged Property, if any portion of the
            improvements on the Mortgaged Property is located in an area
            identified by the Federal Emergency Management Agency or the
            Secretary of Housing and Urban Development as having special flood
            hazards categorized as Zone "A" or Zone "V" and flood insurance is
            available, the terms of the Mortgage Loan require the borrower to
            maintain flood insurance, or at such borrower's failure to do so,
            authorizes the Lender to maintain such insurance at the cost and
            expense of the borrower and such insurance is in full force and
            effect in an amount not less than the lesser of (1) the replacement
            cost of the material improvements on such Mortgaged Property, (2)
            the balance of the Mortgage Loan and (3) the maximum amount of
            insurance available under the applicable National Flood Insurance
            Administration Program;

                  (xlii) With respect to each Mortgage which is a deed of trust,
            a trustee, duly qualified under applicable law to serve as such,
            currently so serves and is named in the deed of trust or has been
            substituted in accordance with applicable law or may be substituted
            in accordance with applicable law by the related mortgagee, and
            except in connection with a trustee's sale after a default by the
            related borrower, no fees are payable to such trustee, and such fees
            payable are payable by the borrower;

                  (xliii) RESERVED;

                  (xliv) Except as disclosed in the Exception Report to this
            Mortgage Loan Purchase Agreement, to the knowledge of the Seller as
            of the date hereof, there was no pending action, suit or proceeding,
            arbitration or governmental investigation against any borrower or
            Mortgaged Property, an adverse outcome of which would materially and
            adversely affect such borrower's ability to perform under the
            related Mortgage Loan;

                  (xlv) No advance of funds has been made by the Seller to the
            related borrower (other than mezzanine debt and the acquisition of
            preferred equity interests by the preferred equity interest holder,
            as disclosed in the Prospectus Supplement), and no funds have, to
            the Seller's knowledge, been received from any person other than, or
            on behalf of, the related borrower, for, or on account of, payments
            due on the Mortgage Loan;

                  (xlvi) To the extent required under applicable law, as of the
            Cut-off Date or as of the date that such entity held the Note, each
            holder of the Note was authorized to transact and do business in the
            jurisdiction in which each related Mortgaged Property is located, or
            the failure to be so authorized did not materially and adversely
            affect the enforceability of such Mortgage Loan;

                  (xlvii) All collateral for the Mortgage Loans is being
            transferred as part of the Mortgage Loans;

                  (xlviii) Except as disclosed in the Exception Report to this
            Mortgage Loan Purchase Agreement or the Prospectus Supplement with
            respect to the Crossed Loans and Multiple Property Loans, no
            Mortgage Loan requires the lender to release any portion of the
            Mortgaged Property from the lien of the related Mortgage except upon
            (a) payment in full or defeasance of the related Mortgage Loan, (b)
            the satisfaction of certain legal and underwriting requirements that
            would be customary for prudent commercial mortgage lenders, which in
            all events include payment of a release price at least 125% of the
            appraised value of the property to be released or of the allocated
            loan amount of such property or (c) releases of unimproved
            out-parcels or (d) releases of other portions of the Mortgaged
            Property which will not have a material adverse effect on the use or
            value of the collateral for the related Mortgage Loan and which were
            given no value in the appraisal of the Mortgaged Property or of that
            portion of the Mortgaged Property used to calculate the
            loan-to-value ratio of the Mortgaged Property for underwriting
            purposes. No release or partial release of any Mortgaged Property,
            or any portion thereof, expressly permitted or required pursuant to
            the terms of any Mortgage Loan would constitute a significant
            modification of the related Mortgage Loan under Treas. Reg. Section
            1.860G-2(b)(2);

                  (xlix) Any insurance proceeds in respect of a casualty loss or
            taking will be applied either to (a) the repair or restoration of
            all or part of the related Mortgaged Property, with, in the case of
            all casualty losses or takings in excess of a specified amount or
            percentage of the related loan amount that a prudent commercial
            lender would deem satisfactory and acceptable, the lender (or a
            trustee appointed by it) having the right to hold and disburse such
            proceeds as the repair or restoration progresses (except in any case
            where a provision entitling another party to hold and disburse such
            proceeds would not be viewed as commercially unreasonable by a
            prudent commercial mortgage lender) or (b) to the payment of the
            outstanding principal balance of such Mortgage Loan together with
            any accrued interest thereon;

                  (l) (l) Each Form UCC-1 financing statement, if any, filed
            with respect to personal property constituting a part of the related
            Mortgaged Property and each Form UCC-2 or UCC-3 assignment, if any,
            of such financing statement to the Seller was, and each Form UCC-3
            assignment, if any, of such financing statement in blank which the
            Trustee or its designee is authorized to complete (but for the
            insertion of the name of the assignee and any related filing
            information which is not yet available to the Seller) is, in
            suitable form for filing in the filing office in which such
            financing statement was filed;

                  (li) To the Seller's knowledge, (a) each commercial lease
            covering more than 10% (20% in the case of any Mortgage Loan having
            an original principal balance less than $2,500,000) of the net
            leaseable area of the related Mortgaged Property is in full force
            and effect and (b) there exists no default under any such commercial
            lease either by the lessee thereunder or by the related borrower
            that could give rise to the termination of such lease;

                  (lii) Based upon an opinion of counsel and/or other due
            diligence considered reasonable by prudent commercial mortgage
            lenders, the improvements located on or forming part of each
            Mortgaged Property comply with applicable zoning laws and
            ordinances, or constitute a legal non-conforming use or structure
            or, if any such improvement does not so comply, such non-compliance
            does not materially and adversely affect the value of the related
            Mortgaged Property. With respect to properties with a Stated
            Principal Balance of over $10,000,000, if the related Mortgaged
            Property does not so comply, to the extent the Seller is aware of
            such non-compliance, it has required the related borrower to obtain
            law and ordinance insurance coverage in amounts customarily required
            by prudent commercial mortgage lenders;

                  (liii) Each Mortgage Loan constitutes a "qualified mortgage"
            within the meaning of Section 860G(a)(3) of the Code (but without
            regard to the rule in Treasury Regulation (as defined herein)
            Section 1.860G-2(f)(2) that treats a defective obligation as a
            qualified mortgage or any substantially similar successor
            provision), the related Mortgaged Property, if acquired by a REMIC
            in connection with the default or imminent default of such Mortgage
            Loan would constitute "foreclosure property" within the meaning of
            Code Section 860G(a)(8) and all Prepayment Premiums and Yield
            Maintenance Charges constitute "customary prepayment penalties"
            within the meaning of Treasury Regulation Section 1.860G-1(b)(2);

                  (liv) With respect to any Mortgage Loan that pursuant to the
            Mortgage Loan Documents can be defeased, (i) the Mortgage Loan
            cannot be defeased within two years after the Closing Date, (ii) the
            borrower can pledge only United States government securities in an
            amount sufficient to make all scheduled payments under the Mortgage
            Loan when due, (iii) the borrower is required to provide independent
            certified public accountant's certification that the collateral is
            sufficient to make such payments, (iv) the loan may be required to
            be assumed by a single-purpose entity designated by the holder of
            the Mortgage Loan, (v) the borrower is required to provide an
            opinion of counsel that the trustee has a perfected security
            interest in such collateral prior to any other claim or interest,
            (vi) the borrower is required to pay all Rating Agency fees
            associated with defeasance (if rating confirmation is a specific
            condition precedent thereto) and all other reasonable expenses
            associated with defeasance, including, but not limited to,
            accountant's fees and opinions of counsel, (vii) with respect to any
            Significant Loan (as defined in the Pooling and Servicing
            Agreement), the borrower is required to provide an opinion of
            counsel that such defeasance will not cause any REMIC created under
            the Pooling and Servicing Agreement to fail to qualify as a REMIC
            for federal or applicable state tax purposes and (viii) with respect
            to any Significant Loan (as defined in the Pooling and Servicing
            Agreement), the borrower must obtain confirmation from each Rating
            Agency that the defeasance would not result in such Rating Agency's
            withdrawal, downgrade or qualification of the then current rating of
            any class of Certificates rated by such Rating Agency;

                  (lv) The Mortgage Loan Documents for each Mortgage Loan
            provide that the related borrower thereunder shall be liable to the
            Seller for any losses incurred by the Seller due to (i) the
            misapplication or misappropriation of rents, insurance proceeds or
            condemnation awards, (ii) any willful act of material waste, (iii)
            any breach of the environmental covenants contained in the related
            Mortgage Loan Documents, and (iv) fraud by the related borrower;
            provided that, with respect to clause (iii) of this sentence, an
            indemnification against losses related to such violations or
            environmental insurance shall satisfy such requirement;

                  (lvi) If such Mortgage Loan is an ARD Loan, it commenced
            amortizing on its initial scheduled Due Date and provides that: (i)
            its Mortgage Rate will increase by no less than two percentage
            points in connection with the passage of its Anticipated Repayment
            Date and so long as the Mortgage Loan is an asset of the Trust Fund;
            (ii) its Anticipated Repayment Date is not less than seven years
            following the origination of such Mortgage Loan; (iii) no later than
            the related Anticipated Repayment Date, if it has not previously
            done so, the related borrower is required to enter into a "lockbox
            agreement" whereby all revenue from the related Mortgaged Property
            shall be deposited directly into a designated account controlled by
            the Master Servicer; and (iv) any cash flow from the related
            Mortgaged Property that is applied to amortize such Mortgage Loan
            following its Anticipated Repayment Date shall, to the extent such
            net cash flow is in excess of the Monthly Payment payable therefrom,
            be net of budgeted and discretionary (servicer approved) capital
            expenditures;

                  (lvii) Except as disclosed in the Prospectus Supplement, no
            Mortgage Loan, and no group of Mortgage Loans made to the same
            borrower and to borrowers that are Affiliates, accounted for more
            than 5.0% of the aggregate of the Stated Principal Balances of all
            of the Mortgage Loans and all of the mortgage loans sold to the
            Depositor by Column Financial Inc. ("Column") pursuant to that
            certain Mortgage Loan Purchase Agreement dated as of July 1, 2002
            between the Depositor, Column and PNC Bank, National Association (in
            its capacity as servicer of certain mortgage loans) as of the
            Cut-Off Date;

                  (lviii) Except for the Mortgage Loans with an initial
            principal balance less than $3,000,000, in connection with its
            origination or acquisition of each Mortgage Loan, the Seller
            obtained an appraisal of the related Mortgaged Property, which
            appraisal is signed by an appraiser, who, to the Seller's actual
            knowledge, had no interest, direct or indirect, in the borrower, the
            Mortgaged Property or in any loan made on the security of the
            Mortgaged Property, and whose compensation was not affected by the
            approval or disapproval of the Mortgage Loan; and

                  (lix) Each Mortgage Loan bears interest at a rate that remains
            fixed throughout the remaining term of such Mortgage Loan, except in
            the case of an ARD Loan after its Anticipated Repayment Date and
            except for the imposition of a default rate.
