         It is the intention of the Seller and the Purchaser that the Purchaser

         The Purchaser and the Seller wish to prescribe the terms and conditions
of the purchase by the Purchaser of the Mortgage Loan.

         In consideration of the premises and the mutual agreements hereinafter
set forth, the Purchaser and the Seller agree as follows:

                                   DEFINITIONS

         All capitalized terms not otherwise defined herein shall have the
meanings ascribed to them in the Trust and Servicing Agreement.

                                   ARTICLE II

                     SALE AND CONVEYANCE OF MORTGAGE LOANS;

does hereby sell, transfer, assign, set over and otherwise convey to the
Purchaser, without recourse, except as expressly set forth herein, all of its

the Servicer pursuant to the terms of the Trust and Servicing Agreement.

         (b) Although the parties intend that the conveyance by the Seller of
its right, title and interest in the Mortgage Loan pursuant to this Agreement
shall constitute a purchase and sale of such Mortgage Loan and not a loan
secured by such Mortgage Loan, if such conveyances are deemed to be a loan, the
parties intend that the rights and obligations of the parties to such loan shall
be established pursuant to the terms of this Agreement. The parties also intend
and agree that the Seller shall be deemed to have granted to the Purchaser, and
the Seller does hereby grant to the Purchaser, a perfected first-priority
security interest in all of its right, title and interest in, to and under the
Mortgage Loan to the extent described in Section 2.01 hereof, and that this
Agreement shall constitute a security agreement under applicable law.

deposit with, or cause to be delivered to and deposited with, the Trustee (with
a copy to the Servicer and the Special Servicer), the Mortgage File.

         Section 3.01 Representations and Warranties of the Seller.

         (a) The Seller hereby represents and warrants to the Purchaser as of
the Settlement Date, or as of such other date specifically provided in such
representation and warranty that:

             (i)  Valid Existence and Authority. The Seller is a corporation
                  -----------------------------
      validly existing and in good standing under the laws of the jurisdiction
      of its incorporation, has the full corporate authority and legal right to
      transfer and convey the Mortgage Loan and to execute and deliver this
      Agreement and to perform in accordance herewith;

             (ii) No Conflicts. Neither the execution and delivery of this
                  ------------
      Agreement, nor the fulfillment of or compliance with the terms and
      conditions of this Agreement, (a) will conflict with or result in a breach
      of any of the terms, conditions or provisions of the Seller's
      organizational documents or any agreement or instrument to which it is now
      a party or by which it is bound, or (b) constitute a default or result in
      an acceleration under any such agreement or instrument, or (c) result in
      the violation of any law, rule, regulation, order, judgment or decree to
      which it or its property is subject, or (d) result in the creation or
      imposition of any lien, charge or encumbrance that would

                                      -2-

<PAGE>

          have an adverse effect upon any of its properties pursuant to the
          terms of any mortgage, contract, deed of trust or other instrument, in
          such case, which would have a material adverse effect on the ability
          of the Seller to perform its obligations hereunder;

               (iii) No Litigation Pending. There is no action, suit, proceeding
                     ---------------------
          or investigation pending or, to the Seller's knowledge, threatened
          against it which, either in any one instance or in the aggregate, if
          decided adversely to the Seller would, in the Seller's good faith,
          reasonable judgment, materially and adversely affect the ability of
          the Seller to perform its obligations hereunder;

               (iv)  No Consent Required. No consent, approval,
                     -------------------
          authorization or order of any court or governmental agency or body is
          required for the execution, delivery and performance by the Seller of
          or compliance by the Seller with this Agreement, or if required, such
          approval has been obtained prior to the Settlement Date;

               (v)   Due Execution and Delivery. This Agreement has been
                     --------------------------
          duly authorized, executed and delivered by the Seller and assuming due
          authorization, execution and delivery by the Purchaser, constitutes a
          valid and legally binding obligation of the Seller enforceable in
          accordance with its terms, except as enforceability may be limited by
          bankruptcy, insolvency, reorganization, moratorium or other similar
          laws affecting the enforcement of creditors' rights in general or the
          rights of creditors of banking institutions and by general principles
          of equity (regardless of whether enforceability is considered in
          equity or at law); and

               (vi)  The Mortgage Loan. The Seller hereby represents and
                     -----------------
          warrants with respect to the Mortgage Loan that:

                     (A) Immediately prior to the sale of the Mortgage Loan to
               the Purchaser, the Seller will be the lawful owner of the
               Mortgage Loan with the right to transfer such Mortgage Loan, free
               and clear of any lien, adverse claim, mortgage, security
               interest, pledge, charge or other encumbrance; and

                     (B) The related assignment of Mortgages, Assignment of Loan
               Documents and Assignment of Leases, respectively, constitutes the
               legal, valid and binding assignment of the Mortgages, Assignment
               of Loan Documents and Assignment of Leases from the Seller to the
               Trustee.

                     (C) Other than payments due but with respect to which the
               applicable grace period has not expired, (1) to the best
               knowledge of the Seller, after due inquiry, there is no material
               default, breach, violation or event of acceleration existing
               under the Mortgage Loan Documents, the Mortgage Note or the
               Mortgages in respect of any payment due and owing to the Seller
               from the Mortgagors; (2) to the Actual Knowledge (as defined
               below) of the Seller, there is no other material default, breach,
               violation or event of acceleration existing under the Mortgage
               Loan Documents, the Mortgage Note or the Mortgages nor is there
               any event which, with the passage of time or with notice and the
               expiration of any grace or cure period, would constitute such a
               material default, breach, violation or

                                      -3-

<PAGE>

          event of acceleration; and (3) to the best knowledge of the Seller,
          after due inquiry, it has not expressly waived any material default,
          breach, violation or event of acceleration under the Mortgage Loan
          Documents, the Mortgage Note or the Mortgages; and

                    (D) To the best knowledge of the Seller, after due inquiry,
          there exists no valid offset, defense, counterclaim or right of
          rescission with respect to the Mortgage Loan Documents, the Mortgage
          Note or the Mortgages which would materially interfere with the
          practical realization of the benefits to the holder of the Mortgage
          Loan of the transactions contemplated in the Mortgage Loan Documents.

          "Actual Knowledge" means, with respect to the Seller, the actual
           ----------------
knowledge of any officer of the Seller having the authority to be, and who is
actively involved in, the origination, administration, servicing and/or sale to
the Purchaser of the Mortgage Loan.

          (b) Pursuant to the Trust and Servicing Agreement, the Seller and the
Purchaser shall be given notice of any breach of any representation and warranty
contained in Section 3.01(a) that materially and adversely affects the value of
the Mortgage Loan or the interests of the Certificateholders therein (any such
breach, a "Breach").
           ------

          (c) Upon notice pursuant to Section 3.01(b) herein, the Seller shall,
not later than 90 days from the Seller's receipt of such notice, cure such
Breach in all material respects; provided, however, that in the event that such
Breach is capable of being cured but not within such 90 day period and the
Seller has commenced and is diligently proceeding with the cure of such Breach
within such 90 day period, the Seller shall have an additional 90 days to
complete such cure; provided, further, that with respect to such additional 90
day period, the Seller shall have delivered an officer's certificate to the
Trustee setting forth the reasons such Breach is not capable of being cured
within the initial 90 day period and what actions the Seller is pursuing in
connection with the cure thereof. If such Breach is in respect of the
representation contained in Section 3.01(a)(vi)(A) or 3.01(a)(vi)(B) of this
Agreement and has not been cured within the time periods provided above, the
Seller shall repurchase the Mortgage Loan at the Repurchase Price (as defined
below). If the Mortgage Loan is to be repurchased, the Seller shall remit the
Repurchase Price in immediately available funds to the Trustee.

          The "Repurchase Price" for the Mortgage Loan in the event of a
               ----------------
repurchase pursuant to this Agreement, shall equal:

                (i)  the outstanding principal balance of the Mortgage Loan as
          of the date of repurchase; plus

                (ii) all accrued and unpaid interest (other than Default
          Interest) on the Mortgage Loan at the applicable weighted average
          interest rate, in effect from time to time, to but not including the
          Monthly Payment Date in the Collection Period of repurchase; plus

                                      -4-

<PAGE>

              (iii) all related unreimbursed Servicing Advances plus accrued
     and unpaid interest on any Advances under the terms of the Trust and
     Servicing Agreement; plus

              (iv)  all reasonable out-of-pocket expenses reasonably incurred
     or to be incurred by the Servicer and the Trustee in respect of the Breach
     giving rise to the repurchase obligation, including any expenses arising
     out of the enforcement of the repurchase obligation.

          (d) Upon any repurchase of a Mortgage Loan contemplated by Section
3.01(c) above, the Purchaser shall tender to the Seller, all portions of the
Mortgage File and other documents pertaining to the Mortgage Loan possessed by
it, and each document that constitutes a part of the Mortgage File that was
endorsed or assigned to the Trustee shall be endorsed or assigned, as the case
may be, to the Seller. In the event that the Purchaser or the Trustee pursues
any remedy against the Seller hereunder, the Purchaser and the Trustee shall
take all reasonable action to ensure that the Seller is subrogated to the rights
of the Purchaser and the Trustee in connection with the Mortgage Loan.

          (e) This Section 3.01 of this Agreement provides the sole remedy for
breaches of the representation contained in clause (a)(vi)(A) and (a)(vi)(B) of
this Section available to the Certificateholders and the Trustee.

          (f) Subject to the terms of this Agreement, the Seller hereby
acknowledges the assignment by the Purchaser to the Trustee, as trustee under
the Trust and Servicing Agreement, for the benefit of the Certificateholders, of
the representations and warranties contained herein and of the obligation of the
Seller to cure any Breach or, if applicable, to repurchase the Mortgage Loan
pursuant to this Section. The Trustee or its designee may enforce such
obligations as provided in the Trust and Servicing Agreement.

          Section 3.02 Representations and Warranties of the Purchaser.

          The Purchaser hereby warrants and represents to, and covenants with,
the Seller as of the Settlement Date hereof that:

duly authorized by all necessary action on the part of the Purchaser; neither
the execution, delivery and performance of this Agreement, nor the consummation

or order binding on the Purchaser; (B) the limited liability company agreement
