EXHIBIT 99.1 WACHOVIA MORTGAGE LOAN PURCHASE AGREEMENT

                                                                    EXHIBIT 99.1

                    WACHOVIA MORTGAGE LOAN PURCHASE AGREEMENT

            This Mortgage Loan Purchase Agreement, dated as of August 1, 2007
(this "Agreement"), is entered into between WACHOVIA BANK, NATIONAL ASSOCIATION
(the "Seller") and WACHOVIA COMMERCIAL MORTGAGE SECURITIES, INC. (the
"Purchaser").

            The Seller intends to sell and the Purchaser intends to purchase
certain multifamily and commercial mortgage loans (the "Mortgage Loans")
identified on the schedule (the "Mortgage Loan Schedule") annexed hereto as
Exhibit A. The Purchaser intends to deposit the Mortgage Loans, along with
certain other mortgage loans (the "Other Mortgage Loans"), into a trust fund
(the "Trust Fund"), the beneficial ownership of which will be evidenced by
multiple classes (each, a "Class") of mortgage pass-through certificates (the
"Certificates"). One or more "real estate mortgage investment conduit" ("REMIC")
elections will be made with respect to most of the Trust Fund. The Trust Fund
will be created and the Certificates will be issued pursuant to a pooling and
servicing agreement (the "Pooling and Servicing Agreement"), dated as of August
1, 2007, among the Purchaser, as depositor, Wachovia Bank, National Association,
as master servicer (in such capacity, the "Master Servicer"), LNR Partners,
Inc., as special servicer (the "Special Servicer") and Wells Fargo Bank, N.A.,
as trustee (the "Trustee"). Capitalized terms used but not defined herein
(including the Schedules attached hereto) have the respective meanings set forth
in the Pooling and Servicing Agreement.

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

            SECTION 1. Agreement to Purchase.

            The Seller agrees to sell, and the Purchaser agrees to purchase, the
Mortgage Loans identified on the Mortgage Loan Schedule. The Mortgage Loan
Schedule may be amended to reflect the actual Mortgage Loans delivered to the
Purchaser pursuant to the terms hereof. The Mortgage Loans are expected to have
an aggregate principal balance of $2,043,814,381 (the "Wachovia Mortgage Loan
Balance") (subject to a variance of plus or minus 5.0%) as of the close of
business on the Cut-Off Date, after giving effect to any payments due on or
before such date, whether or not such payments are received.

            The Wachovia Mortgage Loan Balance, together with the aggregate
principal balance of the Other Mortgage Loans as of the Cut-Off Date (after
giving effect to any payments due on or before such date whether or not such
payments are received), is expected to equal an aggregate principal balance (the
"Cut-Off Date Pool Balance") of $3,602,123,586 (subject to a variance of plus or
minus 5.0%). The purchase and sale of the Mortgage Loans shall take place on
August 22, 2007, or such other date as shall be mutually acceptable to the
parties to this Agreement (the "Closing Date"). The consideration (the
"Aggregate Purchase Price") for the Mortgage Loans shall be equal to (i)       %
of the Wachovia Mortgage Loan Balance as of the Cut-Off Date, plus (ii)
$7,194,771, which amount represents the amount of interest accrued on the
Wachovia Mortgage Loan Balance at the related Net Mortgage Rate for the period
from and including the Cut-Off Date up to but not including the Closing Date.

            The Aggregate Purchase Price shall be paid to the Seller or its
designee by wire transfer in immediately available funds on the Closing Date.

            SECTION 2. Conveyance of Mortgage Loans.

            (a) Effective as of the Closing Date, subject only to receipt by the
Seller of the Aggregate Purchase Price and satisfaction of the other conditions
to closing that are for the benefit of the Seller, the Seller does hereby sell,
transfer, assign, set over and otherwise convey to the Purchaser, without
recourse (except as set forth in this Agreement), all the right, title and
interest of the Seller in and to the Mortgage Loans identified on the Mortgage
Loan Schedule as of such date, on a servicing released basis, together with all
of the Seller's right, title and interest in and to the proceeds of any related
title, hazard, primary mortgage or other insurance proceeds.

            (b) The Purchaser or its assignee shall be entitled to receive all
scheduled payments of principal and interest due after the Cut-Off Date, and all
other recoveries of principal and interest collected after the Cut-Off Date
(other than in respect of principal and interest on the Mortgage Loans due on or
before the Cut-Off Date). All scheduled payments of principal and interest due
on or before the Cut-Off Date but collected on or after the Cut-Off Date, and
recoveries of principal and interest collected on or before the Cut-Off Date
(only in respect of principal and interest on the Mortgage Loans due on or
before the Cut-Off Date and principal prepayments thereon), shall belong to, and
shall be promptly remitted to, the Seller.

            (c) No later than the Closing Date, the Seller shall, on behalf of
the Purchaser, deliver to the Trustee, the documents and instruments specified
below with respect to each Mortgage Loan (each a "Mortgage File"). All Mortgage
Files so delivered will be held by the Trustee in escrow at all times prior to
the Closing Date. Each Mortgage File shall contain the following documents:

            (i) the original executed Mortgage Note including any power of
      attorney related to the execution thereof, together with any and all
      intervening endorsements thereon, endorsed on its face or by allonge
      attached thereto (without recourse, representation or warranty, express or
      implied) to the order of "Wells Fargo Bank, N.A., as trustee for the
      registered holders of Wachovia Bank Commercial Mortgage Trust, Commercial
      Mortgage Pass-Through Certificates, Series 2007-C33" or in blank (or a
      lost note affidavit and indemnity with a copy of such Mortgage Note
      attached thereto);

             (ii) an original or copy of the Mortgage, together with any and all
      intervening assignments thereof, in each case (unless not yet returned by
      the applicable recording office) with evidence of recording indicated
      thereon or certified by the applicable recording office;

            (iii) an original or copy of any related Assignment of Leases (if
      such item is a document separate from the Mortgage), together with any and
      all intervening assignments thereof, in each case (unless not yet returned
      by the applicable recording office) with evidence of recording indicated
      thereon or certified by the applicable recording office;

            (iv) an original executed assignment, in recordable form (except for
      any missing recording information), of (a) the Mortgage, (b) any related
      Assignment of Leases (if such item is a document separate from the
      Mortgage and to the extent not already assigned pursuant to preceding
      clause (a)) and (c) any other recorded document relating to the Mortgage
      Loan otherwise included in the Mortgage File, in favor of "Wells Fargo
      Bank, N.A., as trustee for the registered holders of Wachovia Bank
      Commercial Mortgage Trust, Commercial Mortgage Pass-Through Certificates,
      Series 2007-C33", or in blank;

            (v) an original assignment of all unrecorded documents relating to
      the Mortgage Loan (to the extent not already assigned pursuant to clause
      (iv) above), in favor of "Wells Fargo Bank, N.A., as trustee for the
      registered holders of Wachovia Bank Commercial Mortgage Trust, Commercial
      Mortgage Pass-Through Certificates, Series 2007-C33", or in blank;

            (vi) originals or copies of any modification, consolidation,
      assumption and substitution agreements in those instances where the terms
      or provisions of the Mortgage or Mortgage Note have been consolidated or
      modified or the Mortgage Loan has been assumed or consolidated;

            (vii) the original or a copy of the policy or certificate of
      lender's title insurance or, if such policy has not been issued or
      located, an original or copy of an irrevocable, binding commitment (which
      may be a marked version of the policy that has been executed by an
      authorized representative of the title company or an agreement to provide
      the same pursuant to binding escrow instructions executed by an authorized
      representative of the title company) to issue such title insurance policy;

            (viii) any filed copies (bearing evidence of filing) or other
      evidence of filing satisfactory to the Purchaser of any prior UCC
      Financing Statements in favor of the originator of such Mortgage Loan or
      in favor of any assignee prior to the Trustee (but only to the extent the
      Seller had possession of such UCC Financing Statements prior to the
      Closing Date) and, if there is an effective UCC Financing Statement and
      continuation statement in favor of the Seller on record with the
      applicable public office for UCC Financing Statements, an original UCC
      Amendment, in form suitable for filing in favor of "Wells Fargo Bank,
      N.A., as trustee for the registered holders of Wachovia Bank Commercial
       Mortgage Trust, Commercial Mortgage Pass-Through Certificates, Series
      2007-C33, as assignee", or in blank;

            (ix) an original or copy of (a) any Ground Lease, Memorandum of
      Ground Lease and ground lessor estoppel, (b) any loan guaranty or
      indemnity and (c) any environmental insurance policy;

            (x) any intercreditor agreement relating to permitted debt
      (including, without limitation, mezzanine debt) of the Mortgagor;

            (xi) copies of any loan agreement, escrow agreement or security
      agreement relating to such Mortgage Loan;

            (xii) a copy of any letter of credit and related transfer documents
      relating to such Mortgage Loan;

            (xiii) copies of any management agreement with respect to the
      related Mortgaged Property;

            (xiv) copies of any cash management agreements with respect to the
      related Mortgaged Property;

            (xv) copies of franchise agreements and franchisor comfort letters,
      if any, for hospitality properties and applicable transfer or assignment
      documents; and

            (xvi) with respect to any Companion Loan, all of the above documents
      with respect to such Companion Loan and the related Intercreditor
      Agreement; provided that a copy of each Mortgage Note relating to such
      Companion Loan, rather than the original, shall be provided, and no
      assignments shall be provided.

      Notwithstanding the foregoing, with respect to the ING Hospitality Pool
      Loan, the Wachovia Bank 2007-C32 Trustee will hold the original documents
      (except for the original note, or lost note affidavit, if applicable,
      which will be held by the Trustee) related to the ING Hospitality Pool
      Loan for the benefit of the Wachovia Bank 2007-C32 Trust Fund.

            (d) The Seller shall take all actions reasonably necessary (i) to
permit the Trustee to fulfill its obligations pursuant to Section 2.01(d) of the
Pooling and Servicing Agreement and (ii) to perform its obligations described in
Section 2.01(d) of the Pooling and Servicing Agreement. Without limiting the
generality of the foregoing, if a draw upon a letter of credit is required
before its transfer to the Trust Fund can be completed, the Seller shall draw
upon such letter of credit for the benefit of the Trust Fund pursuant to written
instructions from the Master Servicer. The Seller shall reimburse the Trustee
for all reasonable costs and expenses, if any, incurred by the Trustee for
recording any documents described in Section 2(c)(iv)(c) hereof and filing any
assignments of UCC Financing Statements described in the proviso in the third to
last sentence in Section 2.01(d) of the Pooling and Servicing Agreement.

            (e) All documents and records (except draft documents, privileged
communications and internal correspondence and credit, due diligence and other
underwriting analysis, documents, data or internal worksheets, memoranda,
communications and evaluations of the Seller) relating to each Mortgage Loan and
in the Seller's possession (the "Additional Mortgage Loan Documents") that are
not required to be delivered to the Trustee shall promptly be delivered or
caused to be delivered by the Seller to the Master Servicer or at the direction
of the Master Servicer to the appropriate sub-servicer, together with any
related escrow amounts and reserve amounts.

            (f) The Seller shall take such actions as are reasonably necessary
to assign or otherwise grant to the Trust Fund the benefit of any letters of
credit in the name of the Seller which secure any Mortgage Loan.

            SECTION 3. Representations, Warranties and Covenants of Seller.

            (a) The Seller hereby represents and warrants to and covenants with
the Purchaser, as of the date hereof, that:

            (i) The Seller is a national banking association organized and
      validly existing and in good standing under the laws of the United States
      of America and possesses all requisite authority, power, licenses, permits
      and franchises to carry on its business as currently conducted by it and
      to execute, deliver and comply with its obligations under the terms of
      this Agreement;

            (ii) This Agreement has been duly and validly authorized, executed
      and delivered by the Seller and, assuming due authorization, execution and
      delivery hereof by the Purchaser, constitutes a legal, valid and binding
      obligation of the Seller, enforceable against the Seller in accordance
      with its terms, except as such enforcement may be limited by bankruptcy,
      insolvency, reorganization, receivership, moratorium and other laws
      relating to or affecting the enforcement of creditors' rights in general,
      as they may be applied in the context of the insolvency of a national
      banking association, and by general equity principles (regardless of
      whether such enforcement is considered in a proceeding in equity or at
      law), and by public policy considerations underlying the securities laws,
      to the extent that such public policy considerations limit the
      enforceability of the provisions of this Agreement which purport to
      provide indemnification from liabilities under applicable securities laws;

            (iii) The execution and delivery of this Agreement by the Seller and
      the Seller's performance and compliance with the terms of this Agreement
      will not (A) violate the Seller's articles of association or bylaws, (B)
      violate any law or regulation or any administrative decree or order to
      which it is subject or (C) constitute a material default (or an event
      which, with notice or lapse of time, or both, would constitute a material
      default) under, or result in the breach of, any material contract,
      agreement or other instrument to which the Seller is a party or by which
      the Seller is bound;

            (iv) The Seller is not in default with respect to any order or
      decree of any court or any order, regulation or demand of any federal,
      state, municipal or other governmental agency or body, which default might
      have consequences that would, in the Seller's reasonable and good faith
      judgment, materially and adversely affect the condition (financial or
      other) or operations of the Seller or its properties or have consequences
      that would materially and adversely affect its performance hereunder;

            (v) The Seller is not a party to or bound by any agreement or
      instrument or subject to any articles of association, bylaws or any other
      corporate restriction or any judgment, order, writ, injunction, decree,
      law or regulation that would, in the Seller's reasonable and good faith
      judgment, materially and adversely affect the ability of the Seller to
      perform its obligations under this Agreement or that requires the consent
      of any third person to the execution of this Agreement or the performance
      by the Seller of its obligations under this Agreement (except to the
      extent such consent has been obtained);

            (vi) No consent, approval, authorization or order of any court or
      governmental agency or body is required for the execution, delivery and
      performance by the Seller of or compliance by the Seller with this
      Agreement or the consummation of the transactions contemplated by this
      Agreement except as have previously been obtained, and no bulk sale law
      applies to such transactions;

            (vii) No litigation is pending or, to the Seller's knowledge,
      threatened against the Seller that would, in the Seller's good faith and
      reasonable judgment, prohibit its entering into this Agreement or
      materially and adversely affect the performance by the Seller of its
      obligations under this Agreement;

            (viii) The Seller has caused each Servicing Participant which
      services a Mortgage Loan to comply, as evidenced by written documentation
      between each Servicing Participant and the Seller, with all reporting
      requirements set forth in Sections 3.13, 3.14, 3.22 and 8.17 of the
      Pooling and Servicing Agreement applicable to such Servicing Participant
      for the Mortgage Loans set forth on Exhibit C, for so long as the Trust
      Fund is subject to the reporting requirements of the Securities Exchange
      Act of 1934, as amended;

            (ix) Under generally accepted accounting principles ("GAAP") and for
      federal income tax purposes, the Seller will report the transfer of the
      Mortgage Loans to the Purchaser as a sale of the Mortgage Loans to the
      Purchaser in exchange for consideration consisting of a cash amount equal
      to the Aggregate Purchase Price. The consideration received by the Seller
       upon the sale of the Mortgage Loans to the Purchaser will constitute at
      least reasonably equivalent value and fair consideration for the Mortgage
      Loans. The Seller will be solvent at all relevant times prior to, and will
      not be rendered insolvent by, the sale of the Mortgage Loans to the
      Purchaser. The Seller is not selling the Mortgage Loans to the Purchaser
      with any intent to hinder, delay or defraud any of the creditors of the
      Seller;

            (x) The Seller has examined the Disclosure Material set forth in the
      Preliminary Prospectus Supplement (as defined below), the Prospectus
      Supplement to the accompanying Prospectus (as defined below), the
      Preliminary Memorandum and the Memorandum, relating to the Certificates.
      The Seller hereby represents and warrants that the Disclosure Material is
      appropriately responsive in all material respects to the applicable
      requirements of Items 1104, 1110, 1111, 1117 and 1119 of Regulation AB
       with respect to the Seller and the Wachovia Mortgage Loans; and

            (xi) For so long as the Trust Fund is subject to the reporting
      requirements of the Exchange Act, the Seller shall provide the Purchaser
      (or, with respect to any Companion Loan that is deposited into another
      securitization, the depositor in such other securitization) and the
      Trustee with any Additional Form 10-K Disclosure and any Additional Form
      10-D Disclosure set forth next to the Purchaser's name on Exhibit U and
      Exhibit W, respectively, of the Pooling and Servicing Agreement within the
      time periods set forth in the Pooling and Servicing Agreement.

            (b) The Seller hereby makes the representations and warranties
contained in Schedule I for the benefit of the Purchaser and the Trustee for the
benefit of the Certificateholders as of the Closing Date, with respect to (and
solely with respect to) each Mortgage Loan, which representations and warranties
are subject to the exceptions set forth on Schedule II.

            (c) With respect to the schedule of exceptions delivered by the
Trustee on the Closing Date, within fifteen (15) Business Days (or, in the
reasonable discretion of the Controlling Class Representative, thirty (30)
Business Days) of the Closing Date, with respect to the documents specified in
clauses (i), (ii), (vii), (ix) (solely with respect to Ground Leases) and (xii)
of the definition of Mortgage File, the Seller shall cure any material exception
listed therein (for the avoidance of doubt, any deficiencies with respect to the
documents specified in clause (ii) resulting solely from a delay in the return
of the related documents from the applicable recording office, shall be cured in
the time and manner described in Section 2.01(c) of the Pooling and Servicing
Agreement). If such exception is not so cured, the Seller shall either (1)
repurchase the related Mortgage Loan, (2) with respect to exceptions relating to
clause (xii) of the definition of "Mortgage File", deposit with the Trustee an
amount, to be held in trust in a Special Reserve Account pursuant to the Pooling
and Servicing Agreement, equal to the amount of the undelivered letter of credit
(in the alternative, the Seller may deliver to the Trustee, with a certified
copy to the Master Servicer and Trustee, a letter of credit for the benefit of
the Master Servicer on behalf of the Trustee and upon the same terms and
conditions as the undelivered letter of credit) which the Master Servicer on
behalf of the Trustee may use (or draw upon, as the case may be) under the same
circumstances and conditions as the Master Servicer would have been entitled to
draw on the undelivered letter of credit, or (3) with respect to any exceptions
relating to clauses (i), (ii) and (vii), deposit with the Trustee an amount, to
be held in trust in a Special Reserve Account pursuant to the Pooling and
Servicing Agreement, equal to 25% of the Stated Principal Balance of the related
Mortgage Loan on such date. Any funds or letter of credit deposited pursuant to
clauses (2) and (3) above shall be held by the Trustee until the earlier of (x)
the date on which the Master Servicer certifies to the Trustee and the
Controlling Class Representative that such exception has been cured (or the
Trustee certifies the same to the Controlling Class Representative), at which
time such funds or letter of credit, as applicable, shall be returned to the
Seller and (y) thirty (30) Business Days or, if the Controlling Class
Representative has extended the cure period, forty-five (45) Business Days after
the Closing Date; provided, however, that if such exception is not cured within
such thirty (30) Business Days or forty-five (45) Business Days, as the case may
be, (A) in the case of clause (2), the Trustee shall retain the funds on deposit
in the related Special Reserve Account, or letter of credit, as applicable, or
(B) in the case of clause (3), the Seller shall repurchase the related Mortgage
Loan in accordance with the terms and conditions of this Agreement, at which
time such funds shall be applied to the Purchase Price of the related Mortgage
Loan and any letter of credit will be returned to the Seller.

            If the Seller receives written notice of a Document Defect or a
Breach pursuant to Section 2.03(a) of the Pooling and Servicing Agreement
relating to a Mortgage Loan, then the Seller shall not later than ninety (90)
days from receipt of such notice (or, in the case of a Document Defect or Breach
relating to a Mortgage Loan not being a "qualified mortgage" within the meaning
of the REMIC Provisions (a "Qualified Mortgage"), not later than ninety (90)
days from the date that any party to the Pooling and Servicing Agreement
discovers such Document Defect or Breach; provided the Seller receives such
notice in a timely manner), if such Document Defect or Breach shall materially
and adversely affect the value of the applicable Mortgage Loan, the interest of
the Trust Fund therein or the interests of any Certificateholder, cure such
Document Defect or Breach, as the case may be, in all material respects, which
shall include payment of actual or provable losses and any Additional Trust Fund
Expenses directly resulting from any such Document Defect or Breach or, if such
Document Defect or Breach (other than omissions solely due to a document not
having been returned by the related recording office) cannot be cured within
such 90-day period, (i) repurchase the affected Mortgage Loan at the applicable
Purchase Price not later than the end of such 90-day period or (ii) substitute a
Qualified Substitute Mortgage Loan for such affected Mortgage Loan not later
than the end of such 90-day period (and in no event later than the second
anniversary of the Closing Date) and pay the Master Servicer for deposit into
the Certificate Account, any Substitution Shortfall Amount in connection
therewith; provided, however, that unless the Breach would cause the Mortgage
Loan not to be a Qualified Mortgage, and if such Document Defect or Breach is
capable of being cured but not within such 90-day period and the Seller has
commenced and is diligently proceeding with the cure of such Document Defect or
Breach within such 90-day period, such Seller shall have an additional ninety
(90) days to complete such cure (or, failing such cure, to repurchase or
substitute the related Mortgage Loan); provided, further, that with respect to
such additional 90-day period the Seller shall have delivered an officer's
certificate to the Trustee setting forth what actions the Seller is pursuing in
connection with the cure thereof and stating that the Seller anticipates that
such Document Defect or Breach will be cured within the additional 90-day
period; provided, further, that no Document Defect (other than with respect to a
Mortgage Note, Mortgage, title insurance policy, Ground Lease, any letter of
credit, any franchise agreement, any comfort letter and (if required) any
comfort letter transfer documents (collectively, the "Core Material Documents"))
shall be considered to materially and adversely affect the value of the related
Mortgage Loan, the interests of the Trust Fund therein or the interests of any
Certificateholder unless the document with respect to which the Document Defect
exists is required in connection with an imminent enforcement of the mortgagee's
rights or remedies under the related Mortgage Loan, defending any claim asserted
by any borrower or third party with respect to the Mortgage Loan, establishing
the validity or priority of any lien or any collateral securing the Mortgage
Loan or for any immediate significant servicing obligations; provided, further,
with respect to Document Defects which materially and adversely affect the
interests of any Certificateholder, the interests of the Trust Fund therein or
the value of the related Mortgage Loan, other than with respect to Document
Defects relating to the Core Material Documents, any applicable cure period
following the initial 90-day cure period may be extended by the Master Servicer
or the Special Servicer if the document involved is not needed imminently. Such
extension will end upon thirty (30) days notice of such need as reasonably
determined by the Master Servicer or Special Servicer (with a possible thirty
(30) day extension if the Master Servicer or Special Servicer agrees that the
Seller is diligently pursuing a cure). The Seller shall cure all Document
Defects which materially and adversely affect the interests of any
Certificateholder, the interests of the Trust Fund therein or the value of the
related Mortgage Loan, regardless of the document involved, no later than two
years following the Closing Date; provided that the initial 90-day cure period
referenced in this paragraph may not be reduced. For a period of two years from
the Closing Date, so long as there remains any Mortgage File relating to a
Mortgage Loan as to which there is any uncured Document Defect or Breach, the
Seller shall provide the officer's certificate to the Trustee described above as
to the reasons such Document Defect or Breach remains uncured and as to the
actions being taken to pursue cure. Notwithstanding the foregoing, the delivery
of a commitment to issue a policy of lender's title insurance as described in
Representation 12 of Schedule I hereof in lieu of the delivery of the actual
policy of lender's title insurance shall not be considered a Document Defect or
Breach with respect to any Mortgage File if such actual policy of insurance is
delivered to the Trustee or a Custodian on its behalf not later than the 90th
day following the Closing Date.

             If (i) any Mortgage Loan is required to be repurchased or
substituted for in the manner described above, (ii) such Mortgage Loan is
cross-collateralized and cross-defaulted with one or more other Mortgage Loans
(each, a "Crossed Loan"), and (iii) the applicable Document Defect or Breach
does not constitute a Document Defect or Breach, as the case may be, as to any
other Crossed Loan in such Crossed Group (without regard to this paragraph),
then the applicable Document Defect or Breach, as the case may be, will be
deemed to constitute a Document Defect or Breach, as the case may be, as to any
other Crossed Loan in the Crossed Group for purposes of this paragraph, and the
Seller will be required to repurchase or substitute for all of the remaining
Crossed Loan(s) in the related Crossed Group as provided in the immediately
preceding paragraph unless such other Crossed Loans in such Crossed Group
satisfy the Crossed Loan Repurchase Criteria and satisfy all other criteria for
substitution or repurchase of Mortgage Loans set forth herein. In the event that
the remaining Crossed Loans satisfy the aforementioned criteria, the Seller may
elect either to repurchase or substitute for only the affected Crossed Loan as
to which the related Breach or Document Defect exists or to repurchase or
substitute for all of the Crossed Loans in the related Crossed Group. The Seller
shall be responsible for the cost of any Appraisal required to be obtained by
the Master Servicer to determine if the Crossed Loan Repurchase Criteria have
been satisfied, so long as the scope and cost of such Appraisal has been
approved by the Seller (such approval not to be unreasonably withheld).

            To the extent that the Seller is required to repurchase or
substitute for a Crossed Loan hereunder in the manner prescribed above while the
Trustee continues to hold any other Crossed Loans in such Crossed Group, neither
the Seller nor the Purchaser shall enforce any remedies against the other's
Primary Collateral, but each is permitted to exercise remedies against the
Primary Collateral securing its respective Crossed Loans, including with respect
to the Trustee, the Primary Collateral securing Crossed Loans still held by the
Trustee.

            If the exercise of remedies by one party would materially impair the
ability of the other party to exercise its remedies with respect to the Primary
Collateral securing the Crossed Loans held by such party, then the Seller and
the Purchaser shall forbear from exercising such remedies until the Mortgage
Loan documents evidencing and securing the relevant Crossed Loans can be
modified in a manner that complies with this Agreement to remove the threat of
material impairment as a result of the exercise of remedies or some other
accommodation can be reached. Any reserve or other cash collateral or letters of
credit securing the Crossed Loans shall be allocated between such Crossed Loans
in accordance with the Mortgage Loan documents, or otherwise on a pro rata basis
based upon their outstanding Stated Principal Balances. Notwithstanding the
foregoing, if a Crossed Loan included in the Trust Fund is modified to terminate
the related cross-collateralization and/or cross-default provisions, as a
condition to such modification, the Seller shall furnish to the Trustee an
Opinion of Counsel that any modification shall not cause an Adverse REMIC Event.
Any expenses incurred in good faith by the Purchaser in connection with such
modification or accommodation (including, but not limited to, recoverable
attorney fees) shall be paid by the Seller.

            (d) In connection with any permitted repurchase or substitution of
one or more Mortgage Loans contemplated hereby, upon receipt of a certificate
from a Servicing Officer certifying as to the receipt of the Purchase Price or
Substitution Shortfall Amount(s), as applicable, in the Certificate Account, and
the delivery of the Mortgage File(s) and the Servicing File(s) for the related
Qualified Substitute Mortgage Loan(s) to the Custodian and the Master Servicer,
respectively, if applicable (i) the Trustee shall execute and deliver such
endorsements and assignments as are provided to it by the Master Servicer, in
each case without recourse, representation or warranty, as shall be necessary to
vest in the Seller, the legal and beneficial ownership of each repurchased
Mortgage Loan or substituted Mortgage Loan, as applicable, (ii) the Trustee, the
Custodian, the Master Servicer and the Special Servicer shall each tender to the
Seller, upon delivery to each of them of a receipt executed by the Seller, all
portions of the Mortgage File and other documents pertaining to such Mortgage
Loan possessed by it, and (iii) the Master Servicer and the Special Servicer
shall release to the Seller any Escrow Payments and Reserve Funds held by it in
respect of such repurchased or substituted Mortgage Loans.

            (e) Without limiting the remedies of the Purchaser, the
Certificateholders or the Trustee on behalf of the Certificateholders pursuant
to this Agreement, it is acknowledged that the representations and warranties
are being made for risk allocation purposes. This Section 3 provides the sole
remedy available to the Certificateholders, or the Trustee on behalf of the
Certificateholders, respecting any Document Defect in a Mortgage File or any
Breach of any representation or warranty set forth in or required to be made
pursuant to this Section 3. Nothing in this Agreement shall prohibit the
Purchaser or its assigns (including the Master Servicer and/or the Special
Servicer) from pursuing any course of action authorized by the Pooling and
Servicing Agreement while the Purchaser asserts a claim or brings a cause of
action to enforce any rights set forth herein against the Seller.

            (f) With respect to any Mortgage Loan which has become a Defaulted
Mortgage Loan under the Pooling and Servicing Agreement or with respect to which
the related Mortgaged Property has been foreclosed and which is the subject of a
repurchase claim under this Agreement, in accordance with Section 2.03 of the
Pooling and Servicing Agreement, the Special Servicer with the consent of the
Controlling Class Representative shall notify the Seller in writing of its
intention to liquidate such Defaulted Mortgage Loan or REO Property at least 45
days prior to any such action. If (a) the Seller consents to such sale and
voluntarily agrees to repurchase such Defaulted Mortgage Loan or REO Property or
(b) a court of competent jurisdiction determines that the Seller is liable under
this Agreement to repurchase such Defaulted Mortgage Loan or REO Property, then
such Seller shall remit to the Purchaser an amount equal to the difference if
any of the price of such Defaulted Mortgage Loan or REO Property as sold and the
price at which the Seller would have had to repurchase such Defaulted Mortgage
Loan or REO Property under this Agreement. The Seller shall have ten (10)
Business Days after receipt of notice to determine whether or not to consent to
such sale. If the Seller does not consent to such sale, the Special Servicer
shall contract with a Determination Party (as defined in the Pooling and
Servicing Agreement) as to the merits of such proposed sale. If the related
Determination Party determines that such proposed sale is in accordance with the
Servicing Standard and the provisions of the Pooling and Servicing Agreement
with respect to the sale of Defaulted Mortgage Loans and REO Properties and,
subsequent to such sale, a court of competent jurisdiction determines that the
Seller was liable under this Agreement and required to repurchase such Defaulted
Mortgage Loan or REO Property in accordance with the terms hereof, then the
Seller shall remit to the Purchaser an amount equal to the difference (if any)
between the proceeds of the related action and the price at which the Seller
would have been obligated to pay had the Seller repurchased such Defaulted
Mortgage Loan or REO Property prior to the execution of a binding contract of
sale with a third party in accordance with the terms hereof including the costs
related to contracting with the related Determination Party; provided that the
foregoing procedure in this Section 3(f) shall not preclude such Seller from
repurchasing the Defaulted Mortgage Loan or REO Property prior to the execution
of a binding contract of sale with a third party in accordance with the other
provisions of this Section 3 (excluding this Section 3(f)). If the related
Determination Party determines that the sale of the related Defaulted Mortgage
Loan or REO Property is not in accordance with the Servicing Standard and the
provisions of the Pooling and Servicing Agreement with respect to the sale of
Defaulted Mortgage Loans and REO Properties and the Special Servicer
subsequently sells such Mortgage Loan or REO Property, then the Seller will not
be liable for any such difference (nor any cost of contracting with the
Determination Party).

            (g) Notwithstanding the foregoing, if there exists a Breach relating
to whether or not the Mortgage Loan documents or any particular Mortgage Loan
document requires the related Mortgagor to bear the costs and expenses
associated with any particular action or matter under such Mortgage Loan
document(s) with respect to matters described in Representations 23 and 43 of
Schedule I hereof, then the Purchaser shall direct the Seller in writing to wire
transfer to the Master Servicer for deposit into the Certificate Account, within
ninety (90) days of the Seller's receipt of such direction, the amount of any
such costs and expenses borne by the Purchaser, the Certificateholders, the
Master Servicer, the Special Servicer and the Trustee on their behalf that are
the basis of such Breach. Upon its making such deposit, the Seller shall be
deemed to have cured such Breach in all respects. Provided such payment is made
in full, this paragraph describes the sole remedy available to the Purchaser,
the Certificateholders, the Master Servicer, the Special Servicer and the
Trustee on their behalf regarding any such Breach and the Seller shall not be
obligated to repurchase the affected Mortgage Loan on account of such Breach or
otherwise cure such Breach.

            SECTION 4. Representations and Warranties of the Purchaser. In order
to induce the Seller to enter into this Agreement, the Purchaser hereby
represents and warrants for the benefit of the Seller as of the date hereof
that:

            (a) The Purchaser is a corporation duly organized, validly existing
and in good standing under the laws of the State of North Carolina. The

Trustee.

            (b) This Agreement has been duly and validly authorized, executed
and delivered by the Purchaser, all requisite action by the Purchaser's
directors and officers has been taken in connection therewith, and (assuming the
due authorization, execution and delivery hereof by the Seller) this Agreement
constitutes the valid, legal and binding obligation of the Purchaser,
enforceable against the Purchaser in accordance with its terms, except as such
enforcement may be limited by (A) laws relating to bankruptcy, insolvency,
reorganization, receivership or moratorium, (B) other laws relating to or
affecting the rights of creditors generally, or (C) general equity principles
(regardless of whether such enforcement is considered in a proceeding in equity
or at law).

            (c) Except as may be required under federal or state securities laws
(and which will be obtained on a timely basis), no consent, approval,
authorization or order of, registration or filing with, or notice to, any
governmental authority or court, is required, under federal or state law, for
the execution, delivery and performance by the Purchaser of or compliance by the
Purchaser with this Agreement, or the consummation by the Purchaser of any
transaction described in this Agreement.

            (d) None of the acquisition of the Mortgage Loans by the Purchaser,
the transfer of the Mortgage Loans to the Trustee, or the execution, delivery or
performance of this Agreement by the Purchaser, results or will result in the
creation or imposition of any lien on any of the Purchaser's assets or property,
or conflicts or will conflict with, results or will result in a breach of, or
require or will require the consent of any third person or constitutes or will
constitute a default under (A) any term or provision of the Purchaser's
certificate of incorporation or bylaws, (B) any term or provision of any
material agreement, contract, instrument or indenture, to which the Purchaser is
a party or by which the Purchaser is bound, or (C) any law, rule, regulation,
order, judgment, writ, injunction or decree of any court or governmental
authority having jurisdiction over the Purchaser or its assets.

            (e) Under GAAP and for federal income tax purposes, the Purchaser
will report the transfer of the Mortgage Loans by the Seller to the Purchaser as
a sale of the Mortgage Loans to the Purchaser in exchange for consideration
consisting of a cash amount equal to the Aggregate Purchase Price.

            (f) There is no action, suit, proceeding or investigation pending or
to the knowledge of the Purchaser, threatened against the Purchaser in any court
or by or before any other governmental agency or instrumentality which would
materially and adversely affect the validity of this Agreement or any action
taken in connection with the obligations of the Purchaser contemplated herein,
or which would be likely to impair materially the ability of the Purchaser to
enter into and/or perform its obligations under the terms of this Agreement.

            (g) The Purchaser is not in default with respect to any order or
decree of any court or any order, regulation or demand of any federal, state,
municipal or governmental agency or body, which default might have consequences
that would materially and adversely affect the condition (financial or other) or
operations of the Purchaser or its properties or might have consequences that
would materially and adversely affect its performance hereunder.

            SECTION 5. Closing. The closing of the sale of the Mortgage Loans
(the "Closing") shall be held at the offices of Cadwalader, Wickersham & Taft

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

            (e) The Seller shall have paid all fees and expenses payable by it
to the Purchaser or otherwise pursuant to this Agreement as of the Closing Date;

subject under the 1933 Act, the 1934 Act or other federal or state statutory law

the related Mortgaged Properties contained in the Data File (it being herein
acknowledged that the Data File was and will be used to prepare the Preliminary
Prospectus Supplement and the Prospectus Supplement, including without
limitation Annex A thereto, any other Time of Sale Information, the Preliminary
Memorandum, the Memorandum and the Diskette with respect to the Registered
Certificates and any items similar to Free Writing Prospectuses forwarded to

Prospectus), (II) any such untrue statement or alleged untrue statement or

to, such Disclosure Material, is with respect to, or arises out of or is based
upon an untrue statement or omission of a material fact with respect to, the
information regarding the Mortgage Loans, the related Mortgagors, the related
Mortgaged Properties and/or the Seller set forth in the Specified Portions of
the Preliminary Prospectus Supplement, the Prospectus Supplement, the
Preliminary Memorandum, or the Memorandum, (III) any such untrue statement or

information concerning the characteristics of the Mortgage Loans, the related
Mortgagors or the related Mortgaged Properties furnished to the Purchaser, the
Underwriters or the Initial Purchaser by the Seller; provided, that the
indemnification provided by this Section 7 shall not apply to the extent that
such untrue statement or omission of a material fact was made as a result of an
error in the manipulation of, or in any calculations based upon, or in any
aggregation of the information regarding the Mortgage Loans, the related
Mortgagors and/or the related Mortgaged Properties set forth in the Data File or
Annex A to the Preliminary Prospectus Supplement or the Prospectus Supplement to
the extent such information was not materially incorrect in the Data File or
such Annex A, as applicable, including without limitation the aggregation of
such information with comparable information relating to the Other Mortgage
Loans. Notwithstanding the foregoing, the indemnification provided in this
Section 7(a) shall not inure to the benefit of any Underwriter or Initial
Purchaser (or to the benefit of any person controlling such Underwriter or
Initial Purchaser) from whom the person asserting claims giving rise to any such
losses, claims, damages, expenses or liabilities purchased Certificates if (x)
the subject untrue statement or omission or alleged untrue statement or omission
made in any Disclosure Material (exclusive of the Prospectus or any corrected or
amended Prospectus or the Memorandum or any corrected or amended Memorandum) is
eliminated or remedied in the Prospectus or the Memorandum or, with respect to
any Time of Sale Information only, by the delivery of a Corrected Free Writing

Seller shall, subject to clause (c) below, reimburse each such indemnified
party, as incurred, for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action.

            (b) For purposes of this Agreement, "Registration Statement" shall

(a "hard copy" of which Data File was initialed on behalf of the Seller and the
Purchaser). "Free Writing Prospectus" shall mean a "free writing prospectus" as
such term is defined pursuant to Rule 405 under the 1933 Act. "Corrected Free
Writing Prospectus" shall mean a Free Writing Prospectus that corrects any
previous Free Writing Prospectus prepared by or on behalf of any Underwriter and

            (c) As promptly as reasonably practicable after receipt by any
person entitled to indemnification under this Section 7 (an "indemnified party")
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the Seller (the "indemnifying
party") under this Section 7, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party will
not relieve it from any liability that it may have to any indemnified party
under Section 7(a) (except to the extent that such omission has prejudiced the
indemnifying party in any material respect) or from any liability which it may
have otherwise than under this Section 7. In case any such action is brought
against any indemnified party and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein, and to the extent that it may elect by written notice delivered to the
indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel selected by the
indemnifying party and reasonably satisfactory to such indemnified party;
provided, however, that if the defendants in any such action include both the
indemnified party and the indemnifying party and the indemnified party or
parties shall have reasonably concluded that there may be legal defenses
available to it or them and/or other indemnified parties that are different from
or additional to those available to the indemnifying party, the indemnified
party shall have the right to select separate counsel to assert such legal
defenses and to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Upon receipt of notice from the indemnifying
party to such indemnified party of its election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in connection with the
assertion of legal defenses in accordance with the proviso to the preceding
sentence (it being understood, however, that the indemnifying party shall not be
liable for the expenses of more than one separate counsel, approved by the
Purchaser, the Underwriters and the Initial Purchaser, representing all the
indemnified parties under Section 7(a) who are parties to such action), (ii) the
indemnifying party shall not have employed counsel reasonably satisfactory to
the indemnified party to represent the indemnified party within a reasonable
time after notice of commencement of the action or (iii) the indemnifying party
has authorized the employment of counsel for the indemnified party at the
expense of the indemnifying party; and except that, if clause (i) or (iii) is
applicable, such liability shall only be in respect of the counsel referred to
in such clause (i) or (iii). Unless it shall assume the defense of any
proceeding, an indemnifying party shall not be liable for any settlement of any
proceeding effected without its written consent but, if settled with such
consent or if there be a final judgment for the plaintiff, the indemnifying
party shall indemnify the indemnified party from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel or any other expenses for which the indemnifying party is obligated
under this subsection, the indemnifying party agrees that it shall be liable for
any settlement of any proceeding effected without its written consent if (i)
such settlement is entered into more than forty-five (45) days after receipt by
such indemnifying party of the aforesaid request and (ii) such indemnifying
party shall not have reimbursed the indemnified party in accordance with such
request prior to the date of such settlement. If an indemnifying party assumes
the defense of any proceeding, it shall be entitled to settle such proceeding
with the consent of the indemnified party or, if such settlement provides for an
unconditional release of the indemnified party in connection with all matters
relating to the proceeding that have been asserted against the indemnified party
in such proceeding by the other parties to such settlement, which release does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party without the consent of the
indemnified party.

            (d) If the indemnification provided for in this Section 7 is
unavailable to an indemnified party under Section 7(a) hereof or insufficient in
respect of any losses, claims, damages or liabilities referred to therein, then
the indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities, in such proportion as is
appropriate to reflect the relative fault of the indemnified and indemnifying
parties in connection with the statements or omissions which resulted in such
losses, claims, damages or liabilities, as well as any other relevant equitable
considerations (taking into account the parties' relative knowledge and access
to information concerning the matter with respect to which the claim was
asserted, the opportunity to correct and prevent any statement or omission or
failure to comply, and any other equitable considerations appropriate under the
circumstances). The relative fault of the indemnified and indemnifying parties
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information supplied by such parties;
provided that no Underwriter or Initial Purchaser shall be obligated to
contribute more than its share of underwriting discounts and commissions and
other fees pertaining to the Certificates, less any damages otherwise paid by
such Underwriter or Initial Purchaser with respect to such loss, liability,
claim, damage or expense. It is hereby acknowledged that the respective
Underwriters' and Initial Purchaser's obligations under this Section 7 shall be
several and not joint. For purposes of this Section, each person, if any, who
controls an Underwriter or an Initial Purchaser within the meaning of Section 15
of the 1933 Act or Section 20 of the 1934 Act, and such Underwriter's or Initial
Purchaser's officers and directors, shall have the same rights to contribution
as such Underwriter or Initial Purchaser, as the case may be, and each director
of the Seller and each person, if any who controls the Seller within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Seller.

            (e) The Purchaser and the Seller agree that it would not be just and
equitable if contribution pursuant to Section 7(d) were determined by pro rata
allocation or by any other method of allocation that does not take account of
the considerations referred to in Section 7(d) above.
