                        MORTGAGE LOAN PURCHASE AGREEMENT

            This Mortgage Loan Purchase Agreement (this "Agreement"), dated as
of September 1, 2007, is made by and between NCB, FCB, a federal savings bank
chartered by the Office of Thrift Supervision of the U.S. Department of Treasury
("Seller"), and CREDIT SUISSE FIRST BOSTON MORTGAGE SECURITIES CORP., a Delaware
corporation ("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 or elsewhere in this Agreement, in the Pooling and Servicing
Agreement specified on such Schedule of Transaction Terms.

            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 schedule (the "Mortgage Loan Schedule")
annexed hereto as Schedule II (each such mortgage loan, a "Mortgage Loan" and,
collectively, the "Mortgage Loans"). Depositor intends to deposit the Mortgage
Loans and other assets into a trust fund (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 and Seller 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 Wells
Fargo Bank, N.A. 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 (xvi) in the definition of Mortgage File
(below) shall be delivered to the applicable Master Servicer for inclusion in
the Servicer File (defined below) with a copy delivered to the Trustee for
inclusion in the Mortgage File; and provided, further, that Seller shall pay (or
cause the related Borrower to pay) any costs of the assignment or amendment of
each letter of credit described under said item (xvi) required in order for the
Trustee 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 thirty (30) days after the Closing Date. In addition, prior to
such assignment or amendment of a letter of credit, Seller will take all
necessary steps to enable the applicable Master Servicer to draw on the related
letter of credit on behalf of the Trustee pursuant to 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
applicable Master Servicer and upon receipt, immediately remitting the proceeds
of such draw (or causing such proceeds to be remitted) to the applicable Master
Servicer.

            Section 2. Closing Date Actions. The sale of the Mortgage Loans
shall take place on the Closing Date, subject to and simultaneously with the
deposit of the Mortgage Loans into the Trust Fund, the issuance of the
Certificates and the sale of (a) the Publicly Offered Certificates by Depositor

Certificates by Depositor to the Initial Purchaser pursuant to the Certificate
Purchase Agreement. The closing (the "Closing") shall take place at the offices
of Cadwalader, Wickersham & Taft LLP, One World Financial Center, New York, New

the Closing Date, the following actions shall take place in sequential order on
the terms set forth herein:

      from Seller, the Mortgage Loans pursuant to this Agreement for the

      Price shall be paid by Depositor to Seller or at its direction by wire
      transfer in immediately available funds to an account designated by Seller
      on or prior to the Closing Date. The "Mortgage Loan Purchase Price" paid
      by Depositor shall be equal to the amount that the Depositor and the
      Seller have mutually agreed upon as the Seller's share of the net
      securitization proceeds from the sale of the Publicly Offered Certificates
      and the Private Certificates set forth in the Closing Statement (which
      amount includes, without limitation, accrued interest. Pursuant to the
      terms of the Pooling and Servicing Agreement, Depositor shall sell all of

      Purchaser, and the Initial Purchaser shall purchase from Depositor, the
      Private Certificates pursuant to the Certificate Purchase Agreement.

            (iii) The Underwriters will offer the Publicly Offered Certificates

      Supplement and the Initial Purchaser will privately place certain classes
      of the Private Certificates pursuant to the Offering Circular.

            Section 3. Conveyance of Mortgage Loans. On the Closing Date, Seller
shall sell, convey, assign and transfer, subject to any related servicing rights

      relating to any modification, waiver or amendment of any term of any
      Mortgage Loan (including fees charged the Borrower) required to be added
      to the Mortgage File pursuant to Section 3.20(j) of the Pooling and
      Servicing Agreement.

            Notwithstanding the foregoing, in the event that, in connection with
any Mortgage Loan, Seller cannot deliver, or cause to be delivered, an original,
counterpart or certified copy, as applicable, of any of the documents and/or
instruments required to be delivered pursuant to clauses (ii), (iv), (viii),
(xi) (other than assignments of UCC Financing Statements to be recorded or filed
in accordance with the transfer contemplated by this Agreement), (xii) and (xiv)
(other than assignments of UCC Financing Statements to be filed in accordance
with the transfer contemplated by the related Mortgage Loan Purchase Agreement)
of the last sentence of the first paragraph of this Section 3, 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, Seller: (i) shall
deliver, or cause to be delivered, to the Trustee or its designee a duplicate
original or true copy of such document or instrument certified by the applicable
public recording or filing office, the applicable title insurance company or
Seller to be a true and complete duplicate original or copy of the original
thereof submitted for recording or filing; and (ii) shall deliver, or cause to
be delivered, to the Trustee or its designee either the original of such
non-delivered document or instrument, or a photocopy thereof (certified by the
appropriate public recording or filing office to be a true and complete copy of
the original thereof submitted for recording or filing), with evidence of
recording or filing thereon (with a copy to the applicable Master Servicer),
within 120 days after the Closing Date, which period may be extended up to two
times, in each case for an additional period of 45 days (provided that Seller,
as certified in writing to the Trustee prior to each such 45-day extension, is
in good faith attempting to obtain from the appropriate recording or filing
office such original or photocopy). Compliance with this paragraph will satisfy
Seller's delivery requirements under this Section 3 with respect to the subject
document(s) and instrument(s).

            Notwithstanding the foregoing, in the event that, in connection with
any Mortgage Loan, Seller cannot deliver, or cause to be delivered, an original,
counterpart or certified copy, as applicable, of any of the documents and/or
instruments required to be delivered pursuant to clauses (ii), (iv), (viii),
(xi) (other than assignments of UCC Financing Statements to be recorded or filed
in accordance with the transfer contemplated by this Agreement), (xii) and (xiv)
(other than assignments of UCC Financing Statements to be filed in accordance
with the transfer contemplated by the related Mortgage Loan Purchase Agreement)
of the last sentence of the first paragraph of this Section 3, with evidence of
recording or filing thereon for any other reason, including without limitation,
that such non-delivered document or instrument has been lost, the delivery
requirements of this Agreement shall be deemed to have been satisfied and such
non-delivered document or instrument shall be deemed to have been included in
the related Mortgage File if a photocopy of such non-delivered document or
instrument (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 (with a copy
to the applicable Master Servicer) or its designee on or before the Closing
Date.

            Notwithstanding the foregoing, in the event that Seller cannot
deliver any UCC Financing Statement assignment with the filing or recording
information of the related UCC Financing Statement with respect to any Mortgage
Loan, solely because such UCC Financing Statement has not been returned by the
public filing or recording office where such UCC Financing Statement has been
delivered for filing or recording, Seller has so notified the Trustee and shall
not be in breach of its obligations with respect to such delivery, provided that
Seller promptly forwards such UCC Financing Statement to the Trustee (with a
copy to the applicable Master Servicer) upon its return, together with the
related original UCC Financing Statement assignment in a form appropriate for
filing or recording.

            Notwithstanding the foregoing, Seller may elect, at its sole cost
and expense, but is not obligated to, 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 (iii), (v), and
(xi) of the last sentence of the first paragraph of this Section 3
(collectively, the "Assignments"), to submit those Assignments for filing and
recording, as the case may be, in the applicable public filing and recording
offices and to deliver those Assignments to the Trustee or its designee as those
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 Seller engages a third-party contractor as
contemplated in the immediately preceding sentence, the rights, duties and
obligations of Seller pursuant to this Agreement remain binding on the Seller;
and, if Seller does not engage a third party as contemplated by the immediately
preceding sentence, then Seller will still be liable for recording and filing
fees and expenses of the Assignments as and to the extent contemplated by
Section 13 hereof.

            Within ten (10) Business Days after the Closing Date, Seller shall
deliver the Servicer Files with respect to each of the Mortgage Loans to the
applicable Master Servicer (or, if applicable, to a Sub-Servicer (with a copy to
the applicable Master Servicer) at the direction of the applicable 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 Seller's possession relating to such
applicable Mortgage Loans (including reserve and escrow agreements, rent rolls,
leases, environmental and engineering reports, third-party underwriting reports,
appraisals, surveys, legal opinions, estoppels, financial statements, operating
statements and any other information provided by the respective Borrower from
time to time, but excluding any draft documents, attorney/client communications,
which are privileged or constitute legal or other due diligence analyses, and
documents prepared by the Seller or any of its Affiliates solely for internal
communication, credit underwriting or due diligence analyses (other than the
underwriting information contained in the related underwriting memorandum or
asset summary report prepared by the Seller in connection with the preparation
of Exhibit A-1 to the Prospectus Supplement)) 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 Mortgage 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 Mortgage Loans in such group of
Crossed Mortgage Loans, the inclusion of the original or certified copy of such
document or instrument in the Mortgage File for any of such Crossed Mortgage
Loans and the inclusion of a copy of such original or certified copy in each of
the Mortgage Files for the other Crossed Mortgage Loans in such group of Crossed
Mortgage 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 Mortgage
Loan.

            Seller shall, promptly after the Closing Date, but in all events
within three (3) Business Days after the Closing Date, cause all funds on
deposit in escrow accounts maintained with respect to the Mortgage Loans in the
name of Seller or any other name, to be transferred to or at the direction of
the applicable Master Servicer (or, if applicable, to a Sub-Servicer at the
direction of the applicable Master Servicer).

            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 due after the Cut-off Date, 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 credit analysis or other internal
uses or any attorney-client privileged communication, 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 applicable Master Servicer via wire transfer for deposit
by the applicable Master Servicer into the Collection Account.

            Seller shall, under generally accepted accounting principles
("GAAP"), report its transfer of the Mortgage Loans to Depositor, as provided
herein, as a sale of the Mortgage Loans to Depositor in exchange for the
consideration specified in Section 2 hereof. In connection with the foregoing,
Seller shall cause all of its financial and accounting records to reflect such
transfer as a sale (as opposed to a secured loan). Seller shall at all times
following the Closing Date cause all of its records and financial statements and
any relevant consolidated financial statements of any direct or indirect parent
to clearly reflect that the Mortgage Loans have been transferred to Depositor
and are no longer available to satisfy claims of Seller's creditors.

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

            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:

            (a) Each of the obligations of Seller required to be performed by it
on or prior to the Closing Date pursuant to the terms of this Agreement shall
have been duly performed and complied with in all material respects; all of the
representations and warranties of Seller under this Agreement (subject to the
exceptions set forth in the Exception Report) shall be true and correct in all
material respects as of the Closing Date; no event shall have occurred with

      and on certificates or other documents furnished by officers of Seller and
      (B) in rendering the opinions expressed above, such counsel may limit such

            (c) Seller shall have performed or complied with all other terms and

      Date, with the resolutions of Depositor authorizing the transactions set

            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 federal
      savings bank 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, investigation, 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 or certificate of incorporation and bylaws or similar type
      organizational documents, as applicable; (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 Depositor to realize on the Mortgage Loans.

            (iv) Seller is solvent and the sale of the 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 present or future creditors. After
      giving effect to its transfer of the Mortgage Loans, as provided herein,
      the value of Seller's assets, either taken at their present fair saleable
      value or at fair valuation, will exceed the amount of Seller's debts and
      obligations, including contingent and unliquidated debts and obligations
      of Seller, and Seller will not be left with unreasonably small assets or
      capital with which to engage in and conduct its business. Seller does not
      intend to, and does not believe that it will, incur debts or obligations
      beyond its ability to pay such debts and obligations as they mature. No
      proceedings looking toward liquidation, dissolution or bankruptcy of
      Seller are pending or contemplated.

            (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 (or any
      agreement or 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 (or any agreement or 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 for the filing or
      recording of assignments and other Mortgage Loan Documents contemplated by
      the terms of this Agreement and 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) In connection with its sale of the Mortgage Loans, Seller is
      receiving new value. The consideration received by Seller upon the sale of
      the Mortgage Loans constitutes at least fair consideration and reasonably
      equivalent value for the 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 or 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. The
      Mortgage Loans do not constitute all or substantially all of Seller's
      assets.

            (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 Depositor hereunder
      except for (A) the reimbursement of expenses as described herein or
      otherwise in connection with the transactions described in Section 2
      hereof and (B) 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
      hereto, subject to 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
      identified on Schedule II.

            (xiii) The information set forth in any Disclosure Information (as
      defined in the NCB, FSB Indemnification Agreement), as last forwarded to
      each prospective investor at or prior to the date on which a contract for
      sale was entered into with such prospective investor, (i) does not contain
      any untrue statement of a material fact or omit to state any material fact
      necessary to make the statements therein, in light of the circumstances
      under which they were made, not misleading and (ii) complies with the
      requirements of and contains all of the applicable information required by
      Regulation AB (as defined in the NCB, FSB Indemnification Agreement); but
      only to the extent that (i) such information regards the Mortgage Loans
      and is contained in the Loan Detail (as defined in the NCB, FSB
      Indemnification Agreement) or, to the extent consistent therewith, the
      Diskette (as defined in the NCB, FSB Indemnification Agreement) or (ii)
      such information regarding the Seller or the Mortgage Loans was contained
      in the Confidential Offering Circular or the Prospectus Supplement under
      the headings "Summary of Prospectus Supplement--Relevant
      Parties/Entities," "--Sponsors and Mortgage Loan Sellers,"
      "--Originators," "--The Underlying Mortgage Loans," "--Source of the
      Underlying Mortgage Loans," "Risk Factors," "Description of the Sponsors
      and Mortgage Loan Sellers," "Description of the Underlying Mortgage Loans"
      and "--Significant Mortgage Loans" and such information does not represent
      an incorrect restatement or an incorrect aggregation of correct
      information regarding the Mortgage Loans contained in the Loan Detail.

            (b) Seller hereby agrees that it shall be deemed to make, as of the
date of substitution, to and for the benefit of the Trustee as the holder of the
Mortgage Loan to be replaced, with respect to any replacement mortgage loan (a
"Replacement Mortgage Loan") that is substituted for a Mortgage Loan affected by
a Material Defect or a Material Breach, pursuant to Section 7 of this Agreement,
each of the representations and warranties set forth in Exhibit A hereto
(references therein to "Closing Date" being deemed to be references to the "date
of substitution" and references therein to "Cut-off Date" being deemed to be
references to the "due date for the subject Replacement Mortgage Loan during the
month of substitution"). From and after the date of substitution, each
Replacement Mortgage Loan, if any, shall be deemed to constitute a "Mortgage
Loan" hereunder for all purposes.

            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 Seller receives notice of a breach of any of the representations
or warranties made by 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) (in either case, subject to the exceptions to such
representations and warranties set forth in the Exception Report), or in the
case of any Replacement Mortgage Loan, as of the date of substitution pursuant
to Section 6(b) (in any such case, a "Breach"), or receives notice 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"
(which term shall include the "Defects" detailed in the immediately following
paragraph) in the related Mortgage File), and if such Breach or Defect, as the
case may be, materially and adversely affects, or is deemed hereby to materially
and adversely affect, the value of any Mortgage Loan or any successor REO Loan
with respect thereto or the interests of the Holders of any Class of
Certificates (in which case such Breach or Defect shall be a "Material Breach"
or a "Material Defect," as applicable), then Seller shall, upon written request
of Depositor, the Trustee, the applicable Master Servicer or the applicable
Special Servicer, not later than the earlier of 90 days from the receipt by
Seller of such notice or discovery by 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, in accordance with the Pooling and
Servicing Agreement, 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 applicable Master Servicer for
deposit into the applicable 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) Seller has commenced and is diligently proceeding with the cure of
such Material Breach or Material Defect within the Initial Resolution Period and
(iv) Seller has delivered to the Rating Agencies, the applicable Master
Servicer, the applicable Special Servicer 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 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 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 applicable Master Servicer, the applicable 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, 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, Seller shall remit the amount of such costs and expenses and upon its
making such remittance, Seller shall be deemed to have cured such Breach in all
respects. With respect to any repurchase of a Mortgage Loan hereunder or 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 Due Date in the month of substitution, and scheduled
payments of principal and interest due with respect to each Mortgage Loan being
repurchased or replaced after the related Cut-off Date and received by the
applicable Master Servicer or the applicable Special Servicer on behalf of the
Trust on or prior to the related date of repurchase or substitution, shall be
part of the Trust Fund; and (C) scheduled payments of principal and interest due
with respect to each such Qualified Substitute Mortgage Loan on or prior to the
Due Date in the month of substitution, and scheduled payments of principal and
interest due with respect to each Mortgage Loan being repurchased or replaced
and received by the applicable Master Servicer or the applicable Special
Servicer on behalf of the Trust after the related date of repurchase or
substitution, shall not be part of the Trust Fund, and Seller (or, if
applicable, any person effecting the related repurchase or substitution in the
place of Seller) shall be entitled to receive such payments promptly following
receipt by the applicable Master Servicer or the applicable 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 "Material Defect": (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 clause (ix) of the last
sentence of the first paragraph of Section 3 hereof; (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 as recorded or
as sent for recordation, together with a certificate stating that the original
intervening assignment was sent for recordation, or a copy of the intervening
assignment and the related recording information; or (e) the absence from the
Servicer File of any required original letter of credit, provided that such
Defect may be cured by any substitute letter of credit or cash reserve on behalf
of the related Borrower; or (f) the absence from the Mortgage File of the
original or a copy of any required ground lease. In addition, 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.
Notwithstanding anything herein to the contrary, the failure to include a
document checklist in a Mortgage File shall in no event constitute a Material
Defect.

            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 a "Material Defect" or "Material Breach," as applicable, and the
Initial Resolution Period for the affected Mortgage Loan shall be 90 days
following the earlier of 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 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 Material Breach or Material Defect is not capable of being so
corrected or cured within such period, then Seller shall repurchase 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 Mortgage 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
Mortgage 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
Mortgage Loan in the Mortgage Group for purposes of the above provisions, and
Seller will be required to repurchase or substitute for such other Crossed
Mortgage Loan(s) in the related Mortgage Group in accordance with the provisions
of this Section 7 unless such other Crossed Mortgage Loans satisfy the Crossed
Mortgage Loan Repurchase Criteria (as defined in the Pooling and Servicing
Agreement) and Seller can satisfy all other criteria for substitution or
repurchase of the affected Mortgage Loan(s) set forth in the Pooling and
Servicing Agreement. In the event that one or more of such other Crossed
Mortgage Loans satisfy the Crossed Mortgage Loan Repurchase Criteria, Seller may
elect either to repurchase or substitute for only the affected Crossed Mortgage
Loan as to which the related Material Breach or Material Defect exists or to
repurchase or substitute for all of the Crossed Mortgage Loans in the related
Mortgage Group. The Seller shall be responsible for the cost of any Appraisal
required to be obtained by the applicable Master Servicer to determine if the
Crossed Mortgage Loan Repurchase Criteria have been satisfied, so long as the
scope and cost of such Appraisal has been approved by 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, 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) 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) 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, any additional amounts necessary to cover all
reasonable out-of-pocket expenses reasonably incurred by the applicable Master
Servicer, the applicable 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 that is being released, and (iii)
such cure by release of such Mortgaged Property is effected within the time
periods specified for a 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 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 Depositor or the Trustee, as the case may be, and Depositor or the
Trustee, as the case may be, upon receipt of such funds (and, in the case of a
substitution, receipt of the Mortgage File(s) fr the related Qualified
Substitute Mortgage Loans(s)), 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 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 Seller set forth
in this Section 7 constitute the sole remedies available to Depositor and its
successors and assigns respecting any Breach or Defect affecting a Mortgage
Loan.

            Section 8. Crossed Mortgage Loans. With respect to any Crossed
Mortgage Loan conveyed hereunder, to the extent that Seller repurchases or
substitutes for an affected Crossed Mortgage Loan in the manner prescribed above
while the Trustee continues to hold any related Crossed Mortgage Loans, Seller
and 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 Mortgage Loan repurchased or substituted by
Seller, on the one hand, and any related Crossed Mortgage Loans still held by
the Trustee, on the other, would no longer be cross-defaulted or
cross-collateralized with one another; provided that Seller shall have furnished
the Trustee, at Seller's expense, with an Opinion of Counsel that such
modification shall not cause an Adverse REMIC Event; and provided, further, that
if such Opinion of Counsel cannot be furnished, Seller and Depositor hereby
agree that such repurchase or substitution of only the affected Crossed Mortgage
Loans, notwithstanding anything to the contrary herein, shall not be permitted
(in which case, the Seller will be obligated to purchase or substitute for all
Crossed Mortgage Loans in the related Mortgage Group (defined above)). Any
reserve or other cash collateral or letters of credit securing the subject
Crossed Mortgage 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. Rating Agency Fees; Costs and Expenses Associated with a
Defeasance. Seller shall pay all Rating Agency fees associated with an
assumption of a Mortgage Loan to the extent such fees have not been paid by the
related Borrower and such Borrower is not required to pay them under the terms
of the related Mortgage Loan Documents in effect on or before the Closing Date,
the payment of which fees shall constitute the sole remedy of any breach by
Seller of the parenthetical in representation (xxviii)(1) set forth on Exhibit A
hereto. Unless the Seller elects to repurchase or substitute for such Mortgage
Loan in accordance with the second paragraph of Section 7 Seller shall pay all
reasonable costs and expenses associated with a defeasance of a Mortgage Loan to
the extent such costs and expenses have not been paid by the related Borrower
and such Borrower is not required to pay them under the terms of the related
Mortgage Loan Documents in effect on or before the Closing Date, the payment of
which fees shall constitute the sole remedy of any breach by Seller of
representation (liii)(F) set forth on Exhibit A hereto unless the Seller elects
to repurchase or substitute for such Mortgage Loan in accordance with the second
paragraph of Section 7.

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

            (a) Depositor is duly organized and is validly existing as a
corporation in good standing under the laws of the State of Delaware, with full
corporate 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
all jurisdictions in which the ownership or lease of its property or the conduct
of its business requires such qualification (except where the failure to qualify
would not have a materially adverse effect on the consummation of any
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 any consent of, notice to, or 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

Seller, 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

Certificateholders) to demand cure, repurchase, or other relief as provided
herein.

            Section 17. Successors. This Agreement shall inure to the benefit of

and permitted assigns, 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 designated
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
August 24, 2007, among Seller, Depositor, the Initial Purchaser and the
Underwriters, relating to, among other things, information regarding the
Mortgage Loans in the Prospectus Supplement and the Offering Circular, 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 18. 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.

            Section 19. Severability. If any provision of this Agreement shall
be prohibited or invalid under applicable law, this Agreement shall be
ineffective only to such extent, without invalidating the remainder of this
Agreement.

            Section 20. Further Assurances. Depositor and Seller agree to
execute and deliver such instruments and take such actions as the other party
may, from time to time, reasonably request in order to effectuate the purpose
and to carry out the terms of this Agreement.

            Section 21. 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 22. 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 other insurance policies,
      identified on the Mortgage Loan Schedule or that constitute 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 clause (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
      clauses (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;

            (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, securities 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; and

            (e) Seller at the direction of 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 and may prepare and file such UCC Financing Statements
as may be necessary or appropriate to accomplish the foregoing.

            Section 23. 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.

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

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 herein below 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:

                  (1) originated by a savings and loan association, savings

            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

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

                        (a) 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;

                        (b) 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;

                        (c) the Mortgage Loan was originated by the
                  Non-Qualified Originator pursuant to an ongoing, standing

                  relationship with the Qualified Originator, either:

                        acquired by the Qualified Originator from such
                        Non-Qualified Originator; or

                              iii. 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

                        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. Each
      related Assignment of Leases 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
      Permitted Encumbrances (as defined below) and 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 (but for the insertion of the name and address of the
      assignee and any related recording information, which is not yet available
      to the Seller), 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 August 24, 2007, 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,
      specimen policy or title commitment in any 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, (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, (d) the rights of tenants, as tenants
      only, under leases, including subleases, pertaining to the related
      Mortgaged Property, (e) if the related Mortgage Loan is
      cross-collateralized with any other Mortgage Loan in the trust fund, the
      lien of the mortgage instrument for that other Mortgage Loan, (f) if the
      related Mortgaged Property is a unit in a condominium, the related
      condominium declaration and (g) other matters to which like properties are
      commonly subject, none of which, individually or in the aggregate,
      materially and adversely interferes with the current use of the Mortgaged
      Property or the security intended to be provided by such Mortgage or with
      the Mortgagor's ability to pay its obligations under the Mortgage Loan
      when they become due or materially and adversely affects the value of the
      Mortgaged Property (items (a), (b), (c), (d), (e), (f) and (g)
      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, the value of the Mortgaged Property or the 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 and/or servicing rights purchase agreements being executed and
      delivered in connection therewith;

            (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 (for purposes of this representation and warranty, taxes and
      assessments shall not be considered due and owing until the date on which
      interest and/or penalties would be payable thereon);

            (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. All such escrows and
      deposits are being conveyed by the Seller 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.
      Notwithstanding the foregoing, 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 elsewhere in this
      Exhibit A or the Exception Report;

            (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/or
      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, or a letter of credit
      in such amount has been provided, 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 $3,500,000, no environmental report may have been obtained, but
      (in such cases where a Phase I environmental report was not obtained) a
      lender's environmental insurance policy was obtained with respect to each
      such Mortgage Loan. Each of such lender's 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 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 direct or indirect interests in the related borrower
      to persons already holding direct or indirect 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) With respect to any Mortgage Loan where all or any material
      portion of the estate of the related borrower therein is a leasehold
      estate under a ground lease, and the related Mortgage does not also
      encumber the related lessor's fee interest in such Mortgaged Property,
      based upon the terms of the ground lease and any estoppel received from
      the ground lessor, the Seller represents and warrants that:

                  (1) The ground lease or a memorandum regarding such ground
            lease has been duly recorded. The ground lease permits the interest
            of the lessee to be encumbered by the related Mortgage and does not
            restrict the use of the related Mortgaged Property by such lessee,
            its successors or assigns in a manner that would materially and
            adversely affect the security provided by the related Mortgage. To
            the Seller's knowledge, there has been no material change in the
            terms of the ground lease since its recordation, except by any
            written instruments which are included in the related mortgage file;

                  (2) The lessor under such ground lease has agreed in a writing
            included in the related mortgage file that the ground lease may not
            be amended, modified, canceled or terminated 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;

                  (3) The ground lease has an original term (or an original term
            plus one or more optional renewal terms, which, under all
            circumstances, may be exercised, and would be enforceable, by the
            lender) that extends not less than 10 years beyond the amortization
            term of the related Mortgage Loan;

                  (4) Based on the title insurance policy (or binding commitment
            therefor) obtained by the Seller, the ground lease is not subject to
            any liens or encumbrances superior to, or of equal priority with,
            the Mortgage, subject to Permitted Encumbrances and liens that
            encumber the ground lessor's fee interest;

                  (5) Under the terms of the ground lease, the ground lease is
            assignable to the lender and its assigns without the consent of the
            lessor thereunder;

                  (6) The ground lease is in full force and effect, the Seller
            has no actual knowledge that any default beyond applicable notice
            and grace periods has occurred, and to the Seller's knowledge, there
            is no existing condition which, but for the passage of time or
            giving of notice, would result in a default under the terms of the
            ground lease;

                  (7) The ground lease or ancillary agreement, which is part of
            the Mortgage File, between the lessor and the lessee requires the
            lessor to give notice of any default by the lessee to the lender;

                  (8) The lender is permitted a reasonable opportunity
            (including, where necessary, sufficient time to gain possession of
            the interest of the lessee under the ground lease through legal
            proceedings, or to take other action so long as the lender is
            proceeding diligently) to cure any default under the ground lease
            which is curable after the receipt of notice of any default before
            the lessor may terminate the ground lease. All rights of the lender
            under the ground lease and the related Mortgage (insofar as it
            relates to the ground lease) may be exercised by or on behalf of the
            lender;

                  (9) The ground lease does not impose any restrictions on
            subletting that would be viewed as commercially unreasonable by a
            prudent commercial mortgage lender. The lessor is not permitted to
            disturb the possession, interest or quiet enjoyment of any subtenant
            of the lessee in the relevant portion of the Mortgaged Property
            subject to the ground lease for any reason, or in any manner, which
            would adversely affect the security provided by the related
            Mortgage;

                  (10) Under the terms of the ground lease and the related
            Mortgage, any related insurance proceeds or condemnation award
            (other than in respect of a total or substantially total loss or
            taking) will be applied either to the repair or restoration of all
            or part of the related Mortgaged Property, with the lender or a
            trustee appointed by it having the right to hold and disburse such
            proceeds as repair or restoration progresses (except in such cases
            where a provision entitling another party to hold and disburse such
            proceeds would not be viewed as commercially unreasonable by a
            prudent commercial mortgage lender), or to the payment of the
            outstanding principal balance of the Mortgage Loan, together with
            any accrued interest, except that in the case of condemnation
            awards, the ground lessor may be entitled to a portion of such
            award;

                  (11) Under the terms of the ground lease and the related
            Mortgage, any related insurance proceeds, or condemnation award in
            respect of a total or substantially total loss or taking of the
            related Mortgaged Property will be applied first to the payment of
            the outstanding principal balance of the Mortgage Loan, together
            with any accrued interest (except as provided by applicable law or
            in cases where a different allocation would not be viewed as
            commercially unreasonable by a prudent commercial mortgage lender,
            taking into account the relative duration of the ground lease and
            the related Mortgage and the ratio of the market value of the
            related Mortgaged Property to the outstanding principal balance of
            such Mortgage Loan). Until the principal balance and accrued
            interest are paid in full, neither the lessee nor the lessor under
            the ground lease will have an option to terminate or modify the
            ground lease without the prior written consent of the lender as a
            result of any casualty or partial condemnation; and

                  (12) Provided that the lender cures any defaults which are
            susceptible to being cured, the lessor has agreed to enter into a
            new lease upon termination of the ground lease for any reason,
            including rejection of the ground lease in a bankruptcy proceeding;

            (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 lender
      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 senior or pari
      passu in right of payment and 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 lender 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 Loan 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) 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;

            (xliv) 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;

            (xlv) 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;

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

            (xlvii) 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, (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);

            (xlviii) 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;

            (xlix) (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;

            (l) 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;

            (li) 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;

            (lii) 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);

            (liii) 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;

            (liv) The Mortgage Loan Documents for each Mortgage Loan provide
      that the related borrower thereunder shall be liable to the lender for any
      losses incurred by the lender 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;

            (lv) 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;

                                   ARTICLE III

                         SERVICING OF THE MORTGAGE LOANS

            Section 3.01 Sub-Servicer to Service.

            (a) The Sub-Servicer, as an independent contractor, shall service
and administer pursuant to this Agreement on behalf of the Master Servicer and
the Trustee in the best interests of and for the benefit of the
Certificateholders in accordance with any and all applicable laws and the terms
of this Agreement and the Mortgage Loans and to the extent consistent with the
foregoing with the Servicing Standard under the Pooling and Servicing Agreement.
For the avoidance of doubt, the Sub-Servicer's obligations and rights under this
Agreement are expressly limited to the Mortgage Loans set forth in Exhibit A.
Without in any way limiting the generality of this Section 3.01(a), the parties
hereto hereby acknowledge that, except as otherwise set forth herein, any or all
of the Sub-Servicer's obligations hereunder may be performed in the
Sub-Servicer's name by CSI.

            (b) The Sub-Servicer shall perform, on behalf of the Master
Servicer, all of the obligations of the Master Servicer (with respect to the
Mortgage Loans subject to this Agreement) as set forth in those sections of the
Pooling and Servicing Agreement incorporated herein pursuant to Section 3.01(c)
of this Agreement (the "Incorporated Sections"), as modified by Section 3.01(c)
of this Agreement, and the Master Servicer shall have the same rights with
respect to the Sub-Servicer that the Trustee, the Depositor, the Underwriters,
the Rating Agencies and the Certificateholders (including, without limitation,
the right of the Special Servicer to direct the Master Servicer during certain
periods) have with respect to the Master Servicer under the Pooling and
Servicing Agreement to the extent that the Sub-Servicer is acting on behalf of
the Master Servicer hereunder and except as otherwise set forth herein. Without
limiting the foregoing, and subject to Section 3.21 of the Pooling and Servicing
Agreement as modified herein, the Sub-Servicer shall service and administer the
Mortgage Loans so long as no such mortgage loan is then a Specially Serviced
Mortgage Loan; provided, however, that the Sub-Servicer shall, under instruction
from the Special Servicer or the Master Servicer, deliver certain statements and
documents reasonably requested by the Special Servicer regarding information
held by the Sub-Servicer and continue to cooperate with the Special Servicer by
providing reasonably requested information regarding the servicing of any such
Specially Serviced Mortgage Loan. All references herein to the respective duties
of the Sub-Servicer and the Special Servicer, and to the areas in which they may
exercise discretion, shall be subject to Section 3.21 of the Pooling and
Servicing Agreement, as modified herein and to the Special Servicer's rights to
service Specially Serviced Mortgage Loans. Except as otherwise set forth below,
for purposes of this Agreement, references to the Trustee, the Depositor, the
Underwriters, the Rating Agencies, and the Certificateholders in the
Incorporated Sections shall be deemed to be references to the Master Servicer
hereunder and references to the Master Servicer in the Incorporated Sections
shall be deemed to be references to the Sub-Servicer hereunder (such
modification of the Incorporated Sections shall be referred to herein as the
"References Modification").

            (c) The following Sections of the Pooling and Servicing Agreement
listed herein and only such Sections, unless otherwise provided in this Section
3.01(c) of this Agreement, are hereby incorporated herein by reference as if
fully set forth herein, and, for purposes of this Agreement, in addition to the
References Modification, are hereby further modified as set forth below (and to
avoid any doubt, any modification is limited to its specific terms and the
section is otherwise fully incorporated herein without limitation):

                  (1) Sections 2.05, 2.06(a) and 2.06(c). The Sub-Servicer makes
            each of the representations and warranties, other than the
            representations set forth in Section 2.06(a)(viii) and Section
            2.06(a)(ix) of the Pooling and Servicing Agreement, that are made by
            the Special Servicer in Section 2.06 of the Pooling and Servicing
            Agreement, except that reference to "Special Servicer" therein shall
            be a reference to the Sub-Servicer. The Sub-Servicer is authorized
            to transact business in each state in which a Mortgaged Property is
            located, if and to the extent required by applicable law. The Master
            Servicer makes each of the representations and warranties, other
            than the representation set forth in Section 2.05 (a)(ix) of the
            Pooling and Servicing Agreement, that it makes pursuant to Section
            2.05 of the Pooling and Servicing Agreement to the Sub-Servicer.

                  (2) Section 3.03(e). The Sub-Servicer shall process any
            requests for releases of Reserve Funds (or draws under any Letter of
            Credit delivered in lieu of Reserve Funds) with respect to the
            Mortgage Loans that are Performing Mortgage Loans and then instruct
            the Master Servicer as to the amount of any related disbursement
            from the Reserve Account (or, as applicable, the amount of any
            related draw under such Letter of Credit). The Master Servicer shall
            make such disbursements from the Reserve Account (or such draw under
            the applicable Letter of Credit, as the case may be) at the
            direction of the Sub-Servicer within three Business Days following
            receipt of notice from the Sub-Servicer, unless the Master Servicer
            has determined that such disbursement is not in accordance with the
            Servicing Standard; provided that the Master Servicer shall be
            entitled to conclusively rely on the determination of the
            Sub-Servicer as to such release requests; provided, further, the
            Master Servicer shall not release any Earn-Out Reserve Funds, or
            return any related Letter of Credit delivered in lieu of Earn-Out
            Reserve Funds, without providing notice to the Special Servicer in
            accordance with Section 3.03(e) of the Pooling and Servicing
            Agreement.

                  (3) Section 3.07(d). In lieu of the Freddie Mac, Fannie Mae or

            policies described in Section 3.07(d) of the Pooling and Servicing
            Agreement, the Sub-Servicer shall cause CSI to maintain CSI's
            current insurance policies and fidelity bonds without any reduction
            in coverages or amounts and as otherwise is consistent with this
            Agreement. The fidelity bond and insurance policies required
            hereunder shall also name the Master Servicer as additional insured
            and loss payee; the Master Servicer shall designate in writing to
            the Sub-Servicer how its name shall appear prior to the
            Sub-Servicer's obligation to provide any certificate of insurance.
            The Sub-Servicer shall provide a certificate of insurance to the
            Master Servicer evidencing fidelity bond and insurance coverage
            required hereunder on or before March 31 of each year, beginning
            March 31, 2008.

                  (4) Section 3.08. With respect to the Mortgage Loans, the
            Sub-Servicer shall neither approve nor consent to an assumption of
            any of the Mortgage Loans or a transfer of interest in the Mortgagor
            nor waive any restrictions contained in the Mortgage on transfer of
            an interest in the Mortgaged Property or Mortgagor or on subordinate
            financing, without the prior written consent of the Special
            Servicer. The Sub-Servicer shall process all assumption or transfer
            of interest requests or subordinate financing requests and then
            forward to the Special Servicer (with a copy to the Master Servicer)
            its recommendation, along with any information in the possession of
            the Sub-Servicer reasonably requested by the Special Servicer in
            analysis of such requests. Any assumption fees, transfer of interest
            fees and any other fees or charges (other than application fees)
            relating to an assumption or transfer of interest request with
            respect to the Mortgage Loans shall be assessed by the Sub-Servicer
            and paid as follows: 50% to the Special Servicer, 25% to the Master
            Servicer and 25% to the Sub-Servicer. The Sub-Servicer shall be
            entitled to 100% of any application fees relating to an assumption
            or transfer of interest request with respect to the Mortgage Loans.

                  (5) Section 3.11. Section 3.11 of the Pooling and Servicing
            Agreement is not incorporated herein. The sole compensation payable
            to the Sub-Servicer with respect to the Mortgage Loans is set forth
            in Section 3.07 of this Agreement and, as applicable, under Section
            3.01(c)(4), Section 3.01(c)(9) and Section 3.01(c)(10) with respect
            to fees and charges relating to assumption, transfer of interest,
            defeasance, modification, waiver and/or amendment requests with
            respect to the Mortgage Loans.

                  (6) Sections 3.12(a) and (b). With respect to the Mortgage
            Loans, the Sub-Servicer shall not prepare any report referred to in
            the Pooling and Servicing Agreement or complete any operating
            statements or rent rolls in respect of the related Mortgaged
            Properties, except that the Sub-Servicer shall complete all
            inspection reports and shall promptly (but in no event later than
            twenty (20) days after the related inspection or collection, as
            applicable) forward to the Master Servicer an electronic copy of all
            photographs included therein and all operating statements, rent
            rolls and other period financial statements collected by the
            Sub-Servicer. The Sub-Servicer will afford the Master Servicer
            reasonable cooperation with respect to any report that the
            Sub-Servicer prepares or receives in connection with Section 3.12(a)
            and Section 3.12(b) of the Pooling and Servicing Agreement, by
            providing such information as the Master Servicer may reasonably
            request in connection with the Master Servicer's responsibilities in
            Section 3.12(a) and Section 3.12(b) of the Pooling and Servicing
            Agreement. The Sub-Servicer shall (at its own expense) at all times
            use diligent, commercially reasonable efforts to obtain and deliver
            to the Master Servicer within five (5) Business Days of receipt by
            the Sub-Servicer, the annual and quarterly operating statements,
            rent rolls and other related period financial statements required to

desirable in respect to this Agreement and the rights and duties of the parties

warranty, covenant or agreement made by the Sub-Servicer herein.

agreement made by the Master Servicer herein; provided that the Master Servicer
shall have no liability to the Sub-Servicer for any action taken at the
direction of the Sub-Servicer (or for refraining, in good faith, from the taking
of any such action) in accordance with Section 3.01(c)(2). The Master Servicer
agrees to use reasonable efforts to pursue the Trust Fund for indemnification
against any loss, liability or expense incurred by a Sub-Servicer in connection
with the performance of the Sub-Servicer's duties and obligations under this
Agreement as to which the Pooling and Servicing Agreement grants to the Master
Servicer a right to indemnification from the Trust Fund, and the Sub-Servicer
shall be entitled to any such sums actually received by the Master Servicer.

            Each indemnified party hereunder shall give prompt written notice to
the indemnitor of matters which may give rise to the liability of such
indemnitor hereunder; provided, however, that failure to give such notice shall
not relieve the indemnitor of any liability except to the extent of actual
prejudice.

and the termination or resignation of the Master Servicer or the Sub-Servicer.

            Section 3.07 Sub-Servicer Compensation with Respect to the Mortgage

Section 7.01 of the Pooling and Servicing Agreement, which event of default
occurred as a direct result of the failure of the Sub-Servicer to perform any
obligation hereunder; or

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

            (e) the Sub-Servicer shall consent to the appointment of a
conservator, receiver, liquidator, trustee or similar official in any
bankruptcy, insolvency, readjustment of debt, marshaling of assets and
liabilities or similar proceedings of or relating to the Sub-Servicer or of or
relating to all or substantially all of its property; or

            (f) the Sub-Servicer shall admit in writing its inability to pay its
debts generally as they become due, file a petition to take advantage of any
applicable bankruptcy, insolvency or reorganization statute, make an assignment
for the benefit of its creditors, voluntarily suspend payment of its
obligations, or take any corporate action in furtherance of the foregoing; or

            (g) the Sub-Servicer receives actual knowledge that (1) a Rating
Agency has qualified, downgraded or withdrawn its rating or ratings on one or
more Classes of Certificates, or (2) that a Rating Agency has placed one or more
Classes of Certificates on "rating watch negative" in contemplation of a rating
downgrade or withdrawal (and such "rating watch negative" placement shall not
have been withdrawn by such Rating Agency within sixty (60) days of the date the
Sub-Servicer obtained such actual knowledge), in the case of either of clauses
(1) or (2), citing servicing concerns with the Sub-Servicer or CSI as the sole
or material factor in such action; or

            (h) the Sub-Servicer shall assign or transfer or attempt to assign
or transfer all or part of its rights and obligations hereunder, except as
permitted by this Agreement.

            If any Event of Default shall occur and be continuing, then, and in
each and every such case, so long as such Event of Default shall not have been
remedied within any applicable cure period, the Master Servicer may terminate,
by notice in writing to the Sub-Servicer, all of the rights and obligations of
the Sub-Servicer as sub-servicer under this Agreement and in and to the Mortgage
Loans and the proceeds thereof. From and after the receipt by the Sub-Servicer
of such written notice, all authority and power of the Sub-Servicer under this
Agreement, whether with respect to the Mortgage Loans or otherwise, shall pass
to and be vested in the Master Servicer pursuant to and under this Section, and,
without limitation, the Master Servicer is hereby authorized and empowered to
execute and deliver, on behalf of and at the expense of the Sub-Servicer, as
attorney-in-fact or otherwise, any and all documents and other instruments, and
to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or
otherwise. The Sub-Servicer agrees that if it is terminated pursuant to this
Section, it shall promptly (and in any event no later than five (5) Business
Days subsequent to its receipt of the notice of termination) provide the Master
Servicer with all documents and records (including, without limitation, those in
electronic form) requested by it to enable it to assume the Sub-Servicer's
functions hereunder, and shall cooperate with the Master Servicer in effecting
the termination of the Sub-Servicer's responsibilities and rights hereunder and
the assumption by a successor of the Sub-Servicer's obligations hereunder. All
accrued and unpaid Sub-Servicing Fees as of the date of termination shall be
paid to the Sub-Servicer.

            Section 4.02 Waiver of Defaults.

            The Master Servicer may waive any default by the Sub-Servicer in the
performance of its obligations hereunder and its consequences. Upon any such
waiver of a past default, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived.

            Section 4.03 Other Remedies of Master Servicer.

            During the continuance of any Event of Default, so long as such
Event of Default shall not have been remedied, the Master Servicer, in addition
to the rights specified in Section 4.01, shall have the right, in its own name,
to take all actions now or hereafter existing at law, in equity or by statute to
enforce its rights and remedies (including the institution and prosecution of
all judicial, administrative and other proceedings and the filing of proofs of
claim and debt in connection therewith). Except as otherwise expressly provided
in this Agreement, no remedy provided for by this Agreement shall be exclusive
of any other remedy, and each and every remedy shall be cumulative and in
addition to any other remedy and no delay or omission to exercise any right or
remedy shall impair any such right or remedy or shall be deemed to be a waiver
of any Event of Default.

                                    ARTICLE V

                                   TERMINATION

            Section 5.01 Termination.

            Except as otherwise specifically set forth herein, the rights,
obligations and responsibilities of the Sub-Servicer shall terminate (without
payment of any penalty or termination fee) (i) upon the later of the final
payment or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan and the disposition of all REO Property and the remittance of all
funds due hereunder; (ii) by mutual consent of the Sub-Servicer and the Master
Servicer in writing; (iii) at the option of any purchaser of the Mortgage Loans
pursuant to the Pooling and Servicing Agreement; or (iv) upon termination of the
Pooling and Servicing Agreement. Any notice of termination shall be in writing
and delivered to the Sub-Servicer as provided in Section 6.05 of this Agreement
and Sub-Servicer shall be paid all accrued and outstanding Sub-Servicing Fees as
of the date of termination.

            Section 5.02 Termination of Duties with Respect to Specially
Serviced Mortgage Loans.

            At such time as any of the Mortgage Loans becomes a Specially
Serviced Mortgage Loan, the obligations and duties of the Sub-Servicer set forth
herein with respect to such Specially Serviced Mortgage Loan that are required
to be performed by the Special Servicer under the Pooling and Servicing
Agreement shall cease; provided, however, that although duties of the
Sub-Servicer shall terminate to the extent transferred to the Special Servicer,
the Sub-Servicer shall retain the Mortgage Loan on its computer system so long
as the Mortgage Loan is a Specially Serviced Mortgage Loan. If a Mortgage Loan
is retained on the computer systems of the Sub-Servicer, the Mortgage Loan shall
be subject to the rights of the Special Servicer while the Mortgage Loan is a
Specially Serviced Mortgage Loan. In addition, the Sub-Servicer shall continue
to perform all of its duties hereunder with respect to a Specially Serviced
Mortgage Loan that are not required to be performed by the Special Servicer
pursuant to the Pooling and Servicing Agreement. If a Specially Serviced
Mortgage Loan becomes a Corrected Mortgage Loan, the Sub-Servicer shall commence
servicing such Corrected Mortgage Loan pursuant to the terms of this Agreement.

                                   ARTICLE VI

            Section 6.01 Successor to the Sub-Servicer.

            Prior to termination of the Sub-Servicer's responsibilities and
duties under this Agreement pursuant to Section 3.04, 4.01 or 5.01 of this
Agreement, the Master Servicer shall (i) succeed to and assume all of the
Sub-Servicer's responsibilities, rights, duties and obligations under this
Agreement, or (ii) appoint a successor which satisfies the criteria for a
successor Sub-Servicer in Section 3.02 of this Agreement and which shall succeed
to all rights and assume all of the responsibilities, duties and liabilities of
the Sub-Servicer under this Agreement accruing following the termination of the
Sub-Servicer's responsibilities, duties and liabilities under this Agreement.

            Section 6.02 Financial Statements.

            The Sub-Servicer shall, upon request, deliver to the Master Servicer
its most recent financial statements and, upon the request of the Master
Servicer, make available such other records relevant to the performance of the
Sub-Servicer's obligations hereunder as may be reasonably requested by the
Master Servicer to the extent required to enable the Master Servicer to fulfill
its related obligations under the Pooling and Servicing Agreement.

            Section 6.03 Closing.

            The closing for the commencement of the Sub-Servicer to perform the
servicing responsibilities under this Agreement with respect to the Mortgage

            Section 6.06 Severability Clause.

            Any part, provision, representation or warranty of this Agreement
which is prohibited or which is held to be void or unenforceable shall be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction as to the Mortgage Loans shall not
invalidate or render unenforceable such provision in any other jurisdiction. If
the invalidity of any part, provision, representation or warranty of this
Agreement shall deprive any party of the economic benefit intended to be
conferred by this Agreement, the parties shall negotiate, in good faith, to
develop a structure the economic effect of which is nearly as possible the same
as the economic effect of this Agreement without regard to such invalidity.

            Section 6.07 Counterparts.

            This Agreement may be executed simultaneously in any number of
counterparts. Each counterpart shall be deemed to be an original, and all such

            Section 6.08 Governing Law.

            In order to, among other things, conform to the governing law
provision of the Pooling and Servicing Agreement, this Agreement shall be
construed in accordance with the laws of the State of New York and the
obligations, rights and remedies of the parties hereunder shall be determined in

            The Sub-Servicer shall keep confidential and shall not divulge to
any party other than CSI, the Master Servicer, the Depositor, the Special
Servicer or the Trustee, without the Master Servicer's prior written consent,
any information pertaining to the Mortgage Loans or any borrower thereunder,
except to the extent that it is appropriate for the Sub-Servicer to do so in
working with third-party vendors, property inspectors, legal counsel, auditors,
taxing authorities or other governmental agencies or in accordance with this
Agreement.

            Section 6.10 Intention of the Parties.

            It is the intention of the parties that the Master Servicer is
conveying, and the Sub-Servicer is receiving, only a contract for servicing the
Mortgage Loans. Accordingly, the parties hereby acknowledge that the Trustee
remains the sole and absolute beneficial owner of the Mortgage Loans and all
rights related thereto.

            Section 6.11 Third Party Beneficiary.

            Each of the Depositor and the Trustee, for the benefit of the
Certificateholders, shall be a third party beneficiary under this Agreement;
provided that, except to the extent the Trustee or its designee assumes the
obligations of the Master Servicer hereunder as contemplated by Section 6.12 of
this Agreement, none of the Depositor, the Trustee, the Trust Fund, any
successor Master Servicer, or any Certificateholder shall have any duties under

enforceable by the Sub-Servicer and the Master Servicer and the respective
successors and assigns of the Sub-Servicer and the Master Servicer. This
Agreement shall not be assigned, pledged or hypothecated by the Sub-Servicer to

Master Servicer shall for any reason no longer act in such capacity under the
Pooling and Servicing Agreement, the Trustee or its designee may thereupon
assume all of the rights and, except to the extent they arose prior to the date
of assumption, obligations of the Master Servicer under this Agreement.

            Section 6.13 Waivers.

            No term or provision of this Agreement may be waived or modified
unless such waiver or modification is in writing and signed by the party against
whom such waiver or modification is sought to be enforced.

            Section 6.14 Exhibits.

            The exhibits to this Agreement are hereby incorporated and made a
part hereof and are an integral part of this Agreement.

            Section 6.15 General Interpretive Principles.

            The article and section headings are for convenience of a reference
only, and shall not limit or otherwise affect the meaning hereof.

regarding the subject matter hereof and may not be varied except by a written
agreement conforming to the provisions of Section 6.18 of this Agreement. All
prior negotiations or representations of the parties are merged into this
Agreement and shall have no force or effect unless expressly stated herein.

            Section 6.17 Further Agreement.

            The Sub-Servicer and the Master Servicer each agree to execute and
deliver to the other such reasonable and appropriate additional documents,
instruments or agreements as may be necessary or appropriate to effectuate the
purposes of this Agreement.

Sub-Servicer and the Master Servicer. No amendment to the Pooling and Servicing
Agreement that purports to change the rights or obligations of the Sub-Servicer
hereunder shall be effective against the Sub-Servicer without the express
written consent of the Sub-Servicer.

                      TO PERFORM SERVICING RESPONSIBILITIES

            The Master Servicer, by execution and delivery of this Agreement,
does hereby contract with the Sub-Servicer, subject to the terms of this
Agreement, for the servicing of the Mortgage Loans. On and after the Closing

                                   ARTICLE III

                         SERVICING OF THE MORTGAGE LOANS

            Section 3.01 Sub-Servicer to Service.

            (a) The Sub-Servicer, as an independent contractor, shall service
and administer pursuant to this Agreement on behalf of the Master Servicer and
the Trustee in the best interests of and for the benefit of the
Certificateholders in accordance with any and all applicable laws and the terms
of this Agreement and the Mortgage Loans and to the extent consistent with the
foregoing with the Servicing Standard under the Pooling and Servicing Agreement.
For the avoidance of doubt, the Sub-Servicer's obligations and rights under this
Agreement are expressly limited to the Mortgage Loans set forth in Exhibit A.
Without in any way limiting the generality of this Section 3.01(a), the parties
hereto hereby acknowledge that, except as otherwise set forth herein, any or all
of the Sub-Servicer's obligations hereunder may be performed in the
Sub-Servicer's name by CSI, provided, however, the Sub-Servicer shall remain
liable to the Master Servicer under this Agreement for performance of its duties
hereunder whether or not such duties are performed by the Sub-Servicer.

            (b) The Sub-Servicer shall perform, on behalf of the Master
Servicer, all of the obligations of the Master Servicer (with respect to the
Mortgage Loans subject to this Agreement) as set forth in those sections of the
Pooling and Servicing Agreement incorporated herein pursuant to Section 3.01(c)
of this Agreement (the "Incorporated Sections"), as modified by Section 3.01(c)
of this Agreement, and the Master Servicer shall have the same rights with
respect to the Sub-Servicer that the Trustee, the Depositor, the Underwriters,
the Rating Agencies and the Certificateholders (including, without limitation,
the right of the Special Servicer to direct the Master Servicer during certain
periods) have with respect to the Master Servicer under the Pooling and
Servicing Agreement to the extent that the Sub-Servicer is acting on behalf of
the Master Servicer hereunder and except as otherwise set forth herein. Without
limiting the foregoing, and subject to Section 3.21 of the Pooling and Servicing
Agreement as modified herein, the Sub-Servicer shall service and administer the
Mortgage Loans so long as no such mortgage loan is then a Specially Serviced
Mortgage Loan; provided, however, that the Sub-Servicer shall, under instruction
from the Special Servicer or the Master Servicer, deliver certain statements and
documents reasonably requested by the Special Servicer regarding information
held by the Sub-Servicer and continue to cooperate with the Special Servicer by
providing reasonably requested information regarding the servicing of any such
Specially Serviced Mortgage Loan. All references herein to the respective duties
of the Sub-Servicer and the Special Servicer, and to the areas in which they may
exercise discretion, shall be subject to Section 3.21 of the Pooling and
Servicing Agreement, as modified herein and to the Special Servicer's rights to
service Specially Serviced Mortgage Loans. Except as otherwise set forth below,
for purposes of this Agreement, references to the Trustee, the Depositor, the
Underwriters, the Rating Agencies, and the Certificateholders in the
Incorporated Sections shall be deemed to be references to the Master Servicer
hereunder and references to the Master Servicer in the Incorporated Sections
shall be deemed to be references to the Sub-Servicer hereunder (such
modification of the Incorporated Sections shall be referred to herein as the
"References Modification").

            (c) The following Sections of the Pooling and Servicing Agreement
listed herein and only such Sections, unless otherwise provided in this Section
3.01(c) of this Agreement, are hereby incorporated herein by reference as if
fully set forth herein, and, for purposes of this Agreement, in addition to the
References Modification, are hereby further modified as set forth below (and to

            Agreement, that are made by the Special Servicer in Section 3.24 of
            the Pooling and Servicing Agreement, except that reference to
            "Special Servicer" therein shall be a reference to the Sub-Servicer.

            disbursements from the Reserve Account (or draw under the applicable
            Letter of Credit, as the case may be) within three Business Days
            following receipt of the Sub-Servicer's recommendation with respect
            to such request.

            assumption or transfer of interest requests or subordinate financing
            requests and related documentation from the related Borrower and

            Servicer) such requests and related documentation. Any assumption
            fees, transfer of interest fees and any other fees or charges (other

            inspection reports and shall promptly (but in no event later than
            twenty (20) days after the related inspection or collection, as
            applicable) forward to the Master Servicer an electronic copy of all

            and Section 3.12(b) (c) and (d) of the Pooling and Servicing
            Agreement, by providing such information as the Master Servicer may
            reasonably request in connection with the Master Servicer's
            responsibilities in Section 3.12(a) (c) and (d) and Section 3.12(b)
            of the Pooling and Servicing Agreement. The Sub-Servicer shall (at

            the Master Servicer required pursuant to Section 3.15 and Section
            6.05 of the Pooling and Servicing Agreement as if the Sub-Servicer
            were the Master Servicer thereunder; provided, however, that the
            Sub-Servicer shall not be required to make available information or
            reports prepared by or entered into by the Special Servicer to the
            extent such information and reports are not in the possession of the
            Sub-Servicer. Upon reasonable prior notice, the Sub-Servicer shall
            provide to the Master Servicer, during normal business hours, access
            to its books and records related to the servicing of the Mortgage
            Loans serviced hereunder (including, at the option of the Master
            Servicer, an on-site review).

                  (8) Section 3.19(f). With respect to the Mortgage Loans
            serviced hereunder, the Sub-Servicer shall fulfill all of the
            obligations of the Master Servicer required pursuant to Section
            3.19(f) of the Pooling and Servicing Agreement as if the
            Sub-Servicer were the Master Servicer thereunder. The Sub-Servicer
            shall promptly notify the Master Servicer upon satisfaction of the
            requirements of Section 3.19(f) of the Pooling and Servicing
            Agreement. Any defeasance fees with respect to the Mortgage Loans

                  (9) Section 3.20. With respect to the Mortgage Loans, the
            Sub-Servicer shall neither approve nor consent to a modification,
            waiver or amendment of any term of a Mortgage Loan (other than as
            set forth in Section 3.01(c)(4) of this Agreement and other than
            with respect to those actions specified in Section 3.20(e) of the
            Pooling and Servicing Agreement) nor waive any restrictions
            contained in the Mortgage on such modifications, waivers or
            amendments, without the prior written consent of the Special
            Servicer. The Sub-Servicer shall collect from the related Borrower
            all requests for modifications, waivers or amendments with respect
            to the Mortgage Loans and all related documentation and then forward
            to the Special Servicer (with a copy to the Master Servicer) such
            requests and documentation. Any fees relating to requests for
            modifications, waivers or amendments with respect to the Mortgage
            Loans shall be paid as follows: 50% to the Special Servicer, 25% to
            the Master Servicer and 25% to the Sub-Servicer.

                  (10) Section 3.21(a). The Sub-Servicer shall promptly notify
            the Master Servicer of any event or circumstance, of which the
            Sub-Servicer becomes aware, that the Sub-Servicer deems to
            constitute a Servicing Transfer Event with respect to the Mortgage
            Loans; provided, however, that in no event shall the Sub-Servicer be
            under any obligation to perform calculations or to monitor financial
            covenants with respect to the Mortgage Loans for the purposes of
            determining the existence of any such event or circumstance. The
            determination as to whether a Servicing Transfer Event has occurred
            shall be made by the Master Servicer or the Special Servicer. Upon
            receipt by the Master Servicer of notice from the Special Servicer
            that a Specially Serviced Mortgage Loan has become a Corrected
            Mortgage Loan, the Master Servicer shall promptly give the
            Sub-Servicer notice thereof and the obligation of the Sub-Servicer
            to service and administer such mortgage loan shall resume.

                  (11) Section 3.22. References to the Master Servicer shall not
            be deemed to be references to the Sub-Servicer for purposes of
            Section 3.22. Each and every one of the terms and conditions of
            Section 3.22 shall be enforceable against the Sub-Servicer in
            accordance with the terms thereof and each requirement for the
            Sub-Servicing Agreement set forth in Section 3.22 is hereby
            incorporated into the Agreement. In addition, the parties hereto
            hereby acknowledge that the Sub-Servicer has retained CSI to
            sub-service the Mortgage Loans. Subject to Section 3.22 of the
            Pooling and Servicing Agreement, the Sub-Servicer may not transfer
            sub-servicing of the Mortgage Loans to an entity other than CSI
            without the consent of the Master Servicer, whose consent shall not
            be unreasonably withheld. In addition, to the extent the
            sub-servicing arrangement between the Sub-Servicer and CSI with
            respect to the Mortgage Loans is terminated for any reason, the
            Sub-Servicer shall retain an entity listed on S&P's Select Servicer
            List as a U.S. Commercial Mortgage Master Servicer to sub-service
            the Mortgage Loans.

consolidated, or any corporation resulting from any merger, conversion or
consolidation to which the Sub-Servicer shall be a party, or any Person
succeeding to the business of the Sub-Servicer, shall be the successor of the

for any action taken or for refraining from the taking of any action in good
faith pursuant to this Agreement or as set forth in any writing from the Master
Servicer, or for errors in judgment; provided, however, that this provision
shall not protect the Sub-Servicer or any such person against liability to the
Master Servicer under Section 3.06, or any liability which would otherwise be
imposed by reason of any breach of the terms and conditions of this Agreement,
or against any expense or liability specifically required to be borne by such
party without right of reimbursement pursuant to the terms hereof. The
Sub-Servicer and any officer, employee or agent of the Sub-Servicer may rely in
good faith on any document of any kind that appears on its face to be properly
executed and submitted by any Person respecting any matters arising hereunder.
The Sub-Servicer shall not be under any obligation to appear in, prosecute or
defend any legal action unless such action is related to its duties under this
Agreement and, unless it is specifically required to bear the costs of such
legal action or, in its opinion does not involve it in any ultimate expense or
liability; provided, however, that the Sub-Servicer may, with the consent of the
Master Servicer, undertake any such action which it may deem necessary or
desirable in respect to this Agreement and the rights and duties of the parties
hereto. In such event, the legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities for which
the Master Servicer will be liable and the Sub-Servicer shall be entitled to be
reimbursed therefor from the Master Servicer upon written demand.

            Section 3.04 Sub-Servicer's Resignation.

            Section 3.05 No Transfer or Assignment of Servicing.

            With respect to the responsibility of the Sub-Servicer to service
Mortgage Loans hereunder, the Sub-Servicer acknowledges that the Master Servicer
has acted in reliance upon the adequacy of the Sub-Servicer's servicing program,
its integrity, financial standing and reputation and the continuance thereof.
Without in any way limiting the generality of this Section 3.05, the parties
hereto hereby acknowledge that, except as otherwise set forth herein, any or all
of the Sub-Servicer's obligations hereunder may be performed in the
Sub-Servicer's name by CSI and that the Sub-Servicer shall neither assign nor
transfer this Agreement or the servicing hereunder nor delegate its rights or
duties hereunder or any portion thereof to any party other than CSI without the
prior written approval of the Master Servicer (which approval shall not be
unreasonably withheld or delayed).

            Section 3.06 Indemnification.

            Notwithstanding the provisions of Section 3.03, the Master Servicer
and any director, officer, agent or employee of the Master Servicer shall be
indemnified and held harmless by the Sub-Servicer against any loss, liability or
expense in connection with any legal action incurred (i) by reason of either the
Sub-Servicer's or CSI's willful misconduct, bad faith or negligence in the
performance of or reckless disregard of the Sub-Servicer's duties hereunder or
(ii) by reason of any breach by the Sub-Servicer or CSI of any representation,
warranty, covenant or agreement made by the Sub-Servicer herein.

            The Sub-Servicer and any director, officer, employee or agent of the
Sub-Servicer shall be indemnified and held harmless by the Master Servicer
against any loss, liability or expense in connection with any legal action
incurred (i) by reason of the Master Servicer's willful misconduct, bad faith or
negligence in the performance of or reckless disregard of its duties hereunder
or (ii) by reason of any breach of any representation, warranty, covenant or
agreement made by the Master Servicer herein; provided that the Master Servicer
shall have no liability to the Sub-Servicer for any action taken at the
direction of the Sub-Servicer (or for refraining, in good faith, from the taking
of any such action) in accordance with Section 3.01(c)(2). The Master Servicer
agrees to use reasonable efforts to pursue the Trust Fund for indemnification
against any loss, liability or expense incurred by a Sub-Servicer in connection
with the performance of the Sub-Servicer's duties and obligations under this
Agreement as to which the Pooling and Servicing Agreement grants to the Master
Servicer a right to indemnification from the Trust Fund, and the Sub-Servicer
shall be entitled to any such sums actually received by the Master Servicer.

            Each indemnified party hereunder shall give prompt written notice to
the indemnitor of matters which may give rise to the liability of such
indemnitor hereunder; provided, however, that failure to give such notice shall
not relieve the indemnitor of any liability except to the extent of actual
prejudice.

            This Section 3.06 shall survive the termination of this Agreement
and the termination or resignation of the Master Servicer or the Sub-Servicer.

            Section 3.07 Sub-Servicer Compensation with Respect to the Mortgage
Loans.

            The Sub-Servicer shall be entitled to a Sub-Servicing Fee with
respect to each Mortgage Loan in an amount equal to the product of (i) the
Sub-Servicing Fee Rate, on a per annum basis and (ii) the outstanding principal
balance of the related Mortgage Loan; provided, however, that any such fee shall
be payable only to the extent that collections of interest on the Mortgage Loan
is sufficient to cover the Sub-Servicing Fee to the extent that the related
Mortgage Loan is not then a Specially Serviced Mortgage Loan or a defeased Loan.

            The related Sub-Servicing Fee shall be payable on the Servicer
Remittance Date from monthly payments from the related Borrower and shall
include a report indicating (i) the then outstanding principal balance of the
related Mortgage Loan, (ii) the loan paid to date, (iii) the principal and
interest payment received by the Master Servicer on the related Mortgage Loan
and (iv) the amount of the related Sub-Servicing Fee.

            (c) an event of default with respect to the Master Servicer under
Section 7.01 of the Pooling and Servicing Agreement, which event of default
occurred as a direct result of the failure of the Sub-Servicer to perform any

remedied within any applicable cure period, the Master Servicer may terminate,
by notice in writing to the Sub-Servicer, all of the rights and obligations of
the Sub-Servicer as sub-servicer under this Agreement and in and to the Mortgage

to do or accomplish all other acts or things necessary or appropriate to effect
the purposes of such notice of termination, whether to complete the transfer and
endorsement or assignment of the Mortgage Loans and related documents, or

Days subsequent to its receipt of the notice of termination) provide the Master
Servicer with all documents and records (including, without limitation, those in
electronic form) requested by it to enable it to assume the Sub-Servicer's
functions hereunder, and shall cooperate with the Master Servicer in effecting
the termination of the Sub-Servicer's responsibilities and rights hereunder and
the assumption by a successor of the Sub-Servicer's obligations hereunder. All
accrued and unpaid Sub-Servicing Fees as of the date of termination shall be
paid to the Sub-Servicer.

            Section 4.02 Waiver of Defaults.

            The Master Servicer may waive any default by the Sub-Servicer in the
performance of its obligations hereunder and its consequences. Upon any such
waiver of a past default, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been remedied for every

other default or impair any right consequent thereon except to the extent
expressly so waived.

to take all actions now or hereafter existing at law, in equity or by statute to
enforce its rights and remedies (including the institution and prosecution of
all judicial, administrative and other proceedings and the filing of proofs of
claim and debt in connection therewith). Except as otherwise expressly provided
in this Agreement, no remedy provided for by this Agreement shall be exclusive

                                    ARTICLE V

                                   TERMINATION

            Section 5.01 Termination.

            Except as otherwise specifically set forth herein, the rights,
obligations and responsibilities of the Sub-Servicer shall terminate (without
payment of any penalty or termination fee) (i) upon the later of the final
payment or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan and the disposition of all REO Property and the remittance of all
funds due hereunder; (ii) by mutual consent of the Sub-Servicer and the Master
Servicer in writing; (iii) at the option of any purchaser of the Mortgage Loans
pursuant to the Pooling and Servicing Agreement; or (iv) upon termination of the
Pooling and Servicing Agreement. Any notice of termination shall be in writing
and delivered to the Sub-Servicer as provided in Section 6.05 of this Agreement
and Sub-Servicer shall be paid all accrued and outstanding Sub-Servicing Fees as
of the date of termination.

            Section 5.02 Termination of Duties with Respect to Specially
Serviced Mortgage Loans.

            At such time as any of the Mortgage Loans becomes a Specially
Serviced Mortgage Loan, the obligations and duties of the Sub-Servicer set forth
herein with respect to such Specially Serviced Mortgage Loan that are required
to be performed by the Special Servicer under the Pooling and Servicing
Agreement shall cease; provided, however, that although duties of the
Sub-Servicer shall terminate to the extent transferred to the Special Servicer,
the Sub-Servicer shall retain the Mortgage Loan on its computer system so long
as the Mortgage Loan is a Specially Serviced Mortgage Loan. If a Mortgage Loan
is retained on the computer systems of the Sub-Servicer, the Mortgage Loan shall
be subject to the rights of the Special Servicer while the Mortgage Loan is a
Specially Serviced Mortgage Loan. In addition, the Sub-Servicer shall continue
to perform all of its duties hereunder with respect to a Specially Serviced
Mortgage Loan that are not required to be performed by the Special Servicer
pursuant to the Pooling and Servicing Agreement. If a Specially Serviced
Mortgage Loan becomes a Corrected Mortgage Loan, the Sub-Servicer shall commence
servicing such Corrected Mortgage Loan pursuant to the terms of this Agreement.

                                   ARTICLE VI

Agreement, the Master Servicer shall (i) succeed to and assume all of the
Sub-Servicer's responsibilities, rights, duties and obligations under this
Agreement, or (ii) appoint a successor which satisfies the criteria for a
successor Sub-Servicer in Section 3.02 of this Agreement and which shall succeed
to all rights and assume all of the responsibilities, duties and liabilities of
the Sub-Servicer under this Agreement accruing following the termination of the
Sub-Servicer's responsibilities, duties and liabilities under this Agreement.

            Section 6.02 Financial Statements.

            The Sub-Servicer shall, upon request, deliver to the Master Servicer
its most recent financial statements and, upon the request of the Master
Servicer, make available such other records relevant to the performance of the
Sub-Servicer's obligations hereunder as may be reasonably requested by the
Master Servicer to the extent required to enable the Master Servicer to fulfill
its related obligations under the Pooling and Servicing Agreement.

            The closing for the commencement of the Sub-Servicer to perform the

            Section 6.06 Severability Clause.

            Any part, provision, representation or warranty of this Agreement
which is prohibited or which is held to be void or unenforceable shall be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction as to the Mortgage Loans shall not
invalidate or render unenforceable such provision in any other jurisdiction. If
the invalidity of any part, provision, representation or warranty of this
Agreement shall deprive any party of the economic benefit intended to be
conferred by this Agreement, the parties shall negotiate, in good faith, to
develop a structure the economic effect of which is nearly as possible the same
as the economic effect of this Agreement without regard to such invalidity.

            Section 6.07 Counterparts.

            This Agreement may be executed simultaneously in any number of
counterparts. Each counterpart shall be deemed to be an original, and all such

provision of the Pooling and Servicing Agreement, this Agreement shall be

            The Sub-Servicer shall keep confidential and shall not divulge to
any party other than CSI, the Master Servicer, the Depositor, the Special
Servicer or the Trustee, without the Master Servicer's prior written consent,
any information pertaining to the Mortgage Loans or any borrower thereunder,
except to the extent that it is appropriate for the Sub-Servicer to do so in
working with third-party vendors, property inspectors, legal counsel, auditors,
taxing authorities or other governmental agencies or in accordance with this
Agreement.

            Section 6.10 Intention of the Parties.

            It is the intention of the parties that the Master Servicer is
conveying, and the Sub-Servicer is receiving, only a contract for servicing the

remains the sole and absolute beneficial owner of the Mortgage Loans and all
rights related thereto.

            Section 6.11 Third Party Beneficiary.

            Each of the Depositor and the Trustee, for the benefit of the
Certificateholders, shall be a third party beneficiary under this Agreement;
provided that, except to the extent the Trustee or its designee assumes the
obligations of the Master Servicer hereunder as contemplated by Section 6.12 of
this Agreement, none of the Depositor, the Trustee, the Trust Fund, any
successor Master Servicer, or any Certificateholder shall have any duties under
this Agreement or any liabilities arising herefrom.

enforceable by the Sub-Servicer and the Master Servicer and the respective
successors and assigns of the Sub-Servicer and the Master Servicer. This
Agreement shall not be assigned, pledged or hypothecated by the Sub-Servicer to

Pooling and Servicing Agreement, the Trustee or its designee may thereupon
assume all of the rights and, except to the extent they arose prior to the date
of assumption, obligations of the Master Servicer under this Agreement.

            Section 6.13 Waivers.

            No term or provision of this Agreement may be waived or modified
unless such waiver or modification is in writing and signed by the party against
whom such waiver or modification is sought to be enforced.

            Section 6.14 Exhibits.

            The exhibits to this Agreement are hereby incorporated and made a

regarding the subject matter hereof and may not be varied except by a written
agreement conforming to the provisions of Section 6.18 of this Agreement. All

      (1) The Master Servicer is a national banking association duly organized,
validly existing and in good standing under the laws of the United States, and
the Master Servicer is in compliance with the laws of each State in which any

its obligations hereunder;

      (2) The execution and delivery of this Agreement by the Master Servicer,
and the performance and compliance with the terms of this Agreement by the
Master Servicer, will not (A) violate the Master Servicer's certificate of
incorporation or charter and by-laws or other comparable organizational
documents or (B) constitute a default (or an event which, with notice or lapse
of time, or both, would constitute a default) under, or result in the breach of,
any material agreement or other material instrument to which it is a party or
which is applicable to it or any of its assets, or (C) result in the violation
of any law, rule, regulation, order, judgment or decree binding on the Master
Servicer which, in the case of either (B) or (C), is likely to materially and
adversely affect the Master Servicer's ability to perform hereunder;

      (3) This Agreement, assuming due authorization, execution and delivery by
the other parties hereto, constitutes a valid, legal and binding obligation of
the Master Servicer, enforceable against the Master Servicer in accordance with
the terms hereof, except as such enforcement may be limited by (A) applicable
bankruptcy, insolvency, reorganization, liquidation, receivership, moratorium
and other laws relating to or affecting creditors' rights generally, and (B)
general principles of equity, regardless of whether such enforcement is
considered in a proceeding in equity or at law;

      (4) The Master Servicer is not in violation with respect to any law, any
order or decree of any court, or any order, regulation or demand of any federal,
state, municipal or governmental agency, which violations are reasonably likely
to have consequences that would materially and adversely affect (A) the
financial condition or operations of the Master Servicer or its properties taken
as a whole or (B) its ability to perform its duties and obligations hereunder;

      (5) No litigation is pending or, to the best of the Master Servicer's
knowledge, threatened against the Master Servicer which, if determined adversely
to the Master Servicer, would prohibit the Master Servicer from entering into
this Agreement or, in the Master Servicer's reasonable judgment, is likely to
materially and adversely affect the ability of the Master Servicer to perform
its obligations under this Agreement;

      (6) No consent, approval, authorization or order of any court or
governmental agency or body is required for the execution, delivery and
performance by such Master Servicer of, or compliance by the Master Servicer
with, this Agreement or the consummation of the Master Servicer's transactions
contemplated by this Agreement, except for any consent, approval, authorization
or order which has been obtained or cannot be obtained prior to the actual
performance by the Master Servicer of its obligations under this Agreement, or
which, if not obtained, would not have a materially adverse effect on the
ability of the Master Servicer to perform its obligations hereunder;

      (7) The Master Servicer has full corporate power and authority to enter
into and perform in accordance with this Agreement, has duly authorized the
execution, delivery and performance of this Agreement, and has duly executed and
