March 22, 2007 (the "Memorandum").

            In consideration of the mutual agreements contained herein, the
Seller and the Purchaser hereby agree as follows:

            Section 1. Agreement to Purchase. The Seller agrees to sell, and the
Purchaser agrees to purchase, on a servicing released basis, the Mortgage Loans
identified on the schedule (the "Mortgage Loan Schedule") annexed hereto as
Exhibit 1, as such schedule may be amended to reflect the actual Mortgage Loans
accepted by the Purchaser pursuant to the terms hereof. The Cut-Off Date with
respect to each Mortgage Loan is such Mortgage Loan's Due Date in the month of
March 2007. The Mortgage Loans and the Other Mortgage Loans will have an
aggregate principal balance 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
received, of $416,431,538. The sale of the Mortgage Loans shall take place on
March 29, 2007 or such other date as shall be mutually acceptable to the parties
hereto (the "Closing Date"). The purchase price to be paid by the Purchaser for
the Mortgage Loans shall equal the amount set forth as such purchase price on
Exhibit 3 hereto. The purchase price shall be paid to the Seller by wire
transfer in immediately available funds on the Closing Date.

            On the Closing Date, the Purchaser will assign to the Trustee
pursuant to the Pooling and Servicing Agreement all of its right, title and
interest in and to the Mortgage Loans and its rights under this Agreement (to
the extent set forth in Section 15), and the Trustee shall succeed to such
right, title and interest in and to the Mortgage Loans and the Purchaser's
rights under this Agreement (to the extent set forth in Section 15).

            Section 2. Conveyance of Mortgage Loans. Effective as of the Closing
Date, subject only to receipt of the consideration referred to in Section 1
hereof and the satisfaction of the conditions specified in Sections 6 and 7
hereof, the Seller does hereby transfer, assign, set over and otherwise convey
to the Purchaser, without recourse, all the right, title and interest of the
Seller, with the understanding that a Servicing Rights Purchase and Sale
Agreement, dated March 29, 2007, will be executed by the Seller and the General
Master Servicer, in and to the Mortgage Loans identified on the Mortgage Loan
Schedule as of the Closing Date. The Mortgage Loan Schedule, as it may be
amended from time to time on or prior to the Closing Date, shall conform to the
requirements of this Agreement and the Pooling and Servicing Agreement. In
connection with such transfer and assignment, the Seller shall deliver to or on
behalf of the Trustee, on behalf of the Purchaser, on or prior to the Closing
Date, the Mortgage Note (as described in clause (a) below) for each Mortgage
Loan and on or prior to the fifth Business Day after the Closing Date, five
limited powers of attorney substantially in the form attached hereto as Exhibit
5 in favor of the Trustee, the applicable Master Servicer and the applicable
Special Servicer to empower the Trustee, the applicable Master Servicer and, in
the event of the failure or incapacity of the Trustee and the applicable Master
Servicer, the applicable Special Servicer, to submit for recording, at the
expense of the Seller, any mortgage loan documents required to be recorded as
described in the Pooling and Servicing Agreement and any intervening assignments
with evidence of recording thereon that are required to be included in the
Mortgage Files (so long as original counterparts have previously been delivered
to the Trustee). The Seller agrees to reasonably cooperate with the Trustee, the
applicable Master Servicer and the applicable Special Servicer in connection
with any additional powers of attorney or revisions thereto that are requested
by such parties for purposes of such recordation. The parties hereto agree that
no such power of attorney shall be used with respect to any Mortgage Loan by or
under authorization by any party hereto except to the extent that the absence of
a document described in the second preceding sentence with respect to such
Mortgage Loan remains unremedied as of the earlier of (i) the date that is 180
days following the delivery of notice of such absence to the Seller, but in no
event earlier than 18 months from the Closing Date, and (ii) the date (if any)
on which such Mortgage Loan becomes a Specially Serviced Mortgage Loan. The
Trustee shall submit such documents for recording, at the Seller's expense,
after the periods set forth above; provided, however, the Trustee shall not
submit such assignments for recording if the Seller produces evidence that it
has sent any such assignment for recording and certifies that the Seller is
awaiting its return from the applicable recording office. In addition, not later
than the 30th day following the Closing Date, the Seller shall deliver to or on
behalf of the Trustee each of the remaining documents or instruments specified
below (with such exceptions and additional time periods as are permitted by this
Section) with respect to each Mortgage Loan (each, a "Mortgage File"). (The
Seller acknowledges that the term "without recourse" does not modify the duties
of the Seller under Section 5 hereof.)

            All Mortgage Files, or portions thereof, delivered prior to the
Closing Date are to be held by or on behalf of the Trustee in escrow on behalf
of the Seller at all times prior to the Closing Date. The Mortgage Files shall
be released from escrow upon closing of the sale of the Mortgage Loans and
payments of the purchase price therefor as contemplated hereby. The Mortgage
File for each Mortgage Loan shall contain the following documents:

            (a) The original Mortgage Note bearing all intervening endorsements,
endorsed in blank or endorsed "Pay to the order of U.S. Bank National
Association, as Trustee for Morgan Stanley Capital I Inc., Commercial Mortgage

warranty" or if the original Mortgage Note is not included therein, then a lost

            (b) The original Mortgage, with evidence of recording thereon, and,
if the Mortgage was executed pursuant to a power of attorney, a certified true

which such power of attorney was executed), or certified by a title insurance
company or escrow company to be a true copy thereof; provided that if such
original Mortgage cannot be delivered with evidence of recording thereon on or
prior to the 90th day following the Closing Date because of a delay caused by
the public recording office where such original Mortgage has been delivered for
recordation or because such original Mortgage has been lost, the Seller shall
deliver or cause to be delivered to the Trustee a true and correct copy of such
Mortgage, together with (i) in the case of a delay caused by the public

            (f) If the related Assignment of Leases is separate from the

the Pooling and Servicing Agreement and the Primary Servicing Agreement or (B)
the original of each letter of credit, if any, constituting additional
collateral for such Mortgage Loan (other than letters of credit representing

which shall be held by the applicable Primary Servicer (or the applicable Master
Servicer) on behalf of the Trustee, with a copy to be held by the Trustee, and
applied, drawn, reduced or released in accordance with documents evidencing or
securing the applicable Mortgage Loan, the Pooling and Servicing Agreement and
the Primary Servicing Agreement (it being understood that the Seller has agreed
(a) that the proceeds of such letter of credit belong to the Trust, (b) to
notify, on or before the Closing Date, the bank issuing the letter of credit
that the letter of credit and the proceeds thereof belong to the Trust, and to
use reasonable efforts to obtain within 30 days (but in any event to obtain

bank (with a copy of such acknowledgement to be sent to the Trustee) and (c) to

accruing from the failure of the Seller to assign the letter of credit

capacity as agent of the Trust, and if the applicable Primary Servicer (or
applicable Master Servicer) sells its rights to service the applicable Mortgage
Loan, the applicable Primary Servicer (or applicable Master Servicer) has agreed
to assign the applicable letter of credit to the Trust or at the direction of
the applicable Special Servicer to such party as such Special Servicer may
instruct, in each case, at the expense of the applicable Primary Servicer (or

            (q) With respect to hospitality properties, a copy of any franchise
agreement, franchise comfort letter and applicable assignment or transfer
documents.

            "Officer's Certificate" shall mean a certificate signed by one or
more of the Chairman of the Board, any Vice Chairman, the President, any Senior
Vice President, any Vice President, any Assistant Vice President, any Treasurer
or any Assistant Treasurer.

            The Assignment of Mortgage, intervening assignments of Mortgage and
assignment of Assignment of Leases referred to in clauses (d), (e) and (f) may
be in the form of a single instrument assigning the Mortgage and the Assignment
of Leases to the extent permitted by applicable law. To avoid the unnecessary
expense and administrative inconvenience associated with the execution and
recording or filing of multiple assignments of mortgages, assignments of leases
(to the extent separate from the mortgages) and assignments of UCC financing
statements, the Seller shall execute, in accordance with the third succeeding
paragraph, the assignments of mortgages, the assignments of leases (to the
extent separate from the mortgages) and the assignments of UCC financing
statements relating to the Mortgage Loans naming the Trustee on behalf of the
Certificateholders as assignee. Notwithstanding the fact that such assignments
of mortgages, assignments of leases (to the extent separate from the assignments
of mortgages) and assignments of UCC financing statements shall name the Trustee
on behalf of the Certificateholders as the assignee, the parties hereto
acknowledge and agree that the Mortgage Loans shall for all purposes be deemed
to have been transferred from the Seller to the Purchaser and from the Purchaser
to the Trustee on behalf of the Certificateholders.

            If the Seller cannot deliver, or cause to be delivered, as to any
Mortgage Loan, any of the documents and/or instruments referred to in clauses
(b), (c), (e) or (f), with evidence of recording thereon, because of a delay
caused by the public recording office where such document or instrument has been
delivered for recordation within such 90-day period, but the Seller delivers a
photocopy thereof (to the extent available, certified by the appropriate county
recorder's office to be a true and complete copy of the original thereof
submitted for recording or, if such certification is not available, together
with an Officer's Certificate of the Seller stating that such document has been
sent to the appropriate public recording official for recordation), to the
Trustee within such 90-day period, the Seller shall then deliver within 180 days
after the Closing Date the recorded document (or within such longer period after
the Closing Date as the Trustee may consent to, which consent shall not be
withheld so long as the Seller is, as certified in writing to the Trustee no
less often than monthly, in good faith attempting to obtain from the appropriate
county recorder's office such original or photocopy).

            The Trustee, as assignee or transferee of the Purchaser, shall be
entitled to all scheduled payments of principal due thereon after the Cut-Off
Date, all other payments of principal collected after the Cut-Off Date (other
than scheduled payments of principal due on or before the Cut-Off Date), and all
payments of interest on the Mortgage Loans allocable to the period commencing on
the Cut-Off Date. All scheduled payments of principal and interest due on or
before the Cut-Off Date and collected after the Cut-Off Date shall belong to the
Seller.

            Within 45 days following the Closing Date, the Seller shall deliver
and the Purchaser, the Trustee or the agents of either may submit or cause to be
submitted for recordation at the expense of the Seller, in the appropriate
public office for real property records, each assignment referred to in clauses
(d) and (f)(ii) above (with recording information in blank if such information
is not yet available). Within 15 days following the Closing Date, the Seller
shall deliver and the Purchaser, the Trustee or the agents of either may submit
or cause to be submitted for filing (except with respect to any Mortgage File
documents recorded in the name of MERS or its designee), at the expense of the
Seller, in the appropriate public office for Uniform Commercial Code financing
statements, the assignment referred to in clause (i) above. If any such document
or instrument is lost or returned unrecorded or unfiled, as the case may be,
because of a defect therein, the Seller shall prepare a substitute therefor or
cure such defect, and the Seller shall, at its own expense (except in the case
of a document or instrument that is lost by the Trustee), record or file, as the
case may be, and deliver such document or instrument in accordance with this
Section 2.

             As to each Mortgage Loan secured by a Mortgaged Property with
respect to which the related Mortgagor has entered into a franchise agreement
and each Mortgage Loan secured by a Mortgaged Property with respect to which a
letter of credit is in place, the Seller shall provide a notice on or prior to
the date that is thirty (30) days after the Closing Date to the franchisor or
the issuing financial institution, as applicable, of the transfer of such
Mortgage Loan to the Trust pursuant to the Pooling and Servicing Agreement, and
inform such parties that any notices to the Mortgagor's lender pursuant to such
franchise agreement or letter of credit should thereafter be forwarded to the
applicable Master Servicer and, with respect to each franchise agreement,
provide a franchise comfort letter to the franchisor on or prior to the date
that is thirty (30) days after the Closing Date. After the Closing Date, with
respect to any letter of credit that has not yet been assigned to the Trust,
upon the written request of the applicable Master Servicer or the applicable
Primary Servicer, the Seller will draw on such letter of credit as directed by
the applicable Master Servicer or such Primary Servicer in such notice to the
extent the Seller has the right to do so.

             Documents that are in the possession of the Seller, its agents or
its subcontractors that relate to the servicing of any Mortgage Loans and that
are not required to be a part of the Mortgage File and are reasonably necessary
for the ongoing administration and/or servicing of the applicable Mortgage Loan
(the "Servicing File") shall be delivered by the Seller to or at the direction
of the applicable Master Servicer, on behalf of the Purchaser, on or prior to
the 75th day after the Closing Date, in accordance with the Primary Servicing
Agreement, if applicable.

            The Servicing File shall include, to the extent required to be (and
actually) delivered to the Seller pursuant to the applicable Mortgage Loan
documents, copies of the following items: the Mortgage Note, any Mortgage, the
Assignment of Leases and the Assignment of Mortgage, any guaranty/indemnity
agreement, any loan agreement, the insurance policies or certificates, as
applicable, the property inspection reports, any financial statements on the
property, any escrow analysis, the tax bills, the Appraisal, the environmental
report, the engineering report, the asset summary, financial information on the
Mortgagor/sponsor and any guarantors, any letters of credit, any intercreditor
agreements and any Environmental Insurance Policies; provided, however, the
Seller shall not be required to deliver any draft documents, attorney-client
privileged communications, internal correspondence or credit analysis. Delivery
of any of the foregoing documents to the Primary Servicer shall be deemed a
delivery to the applicable Master Servicer and satisfy Seller's obligations
under this sub-paragraph. Each of the foregoing items shall be delivered by the
Seller in electronic form, to the extent such document is available in such form
and such form is reasonably acceptable to the applicable Master Servicer.

            Upon the sale of the Mortgage Loans by the Seller to the Purchaser
pursuant to this Agreement, the ownership of each Mortgage Note, Mortgage and
the other contents of the related Mortgage File shall be vested in the Purchaser
and its assigns, and the ownership of all records and documents with respect to
the related Mortgage Loan prepared by or that come into the possession of the
Seller shall immediately vest in the Purchaser and its assigns, and shall be
delivered promptly by the Seller to or on behalf of either the Trustee or the
applicable Master Servicer as set forth herein, subject to the requirements of
the Primary Servicing Agreement. The Seller's and Purchaser's records shall
reflect the transfer of each Mortgage Loan from the Seller to the Purchaser and
its assigns as a sale.

            It is the express intent of the parties hereto that the conveyance
of the Mortgage Loans and related property to the Purchaser by the Seller as
provided in this Section 2 be, and be construed as, an absolute sale of the
Mortgage Loans and related property. It is, further, not the intention of the
parties that such conveyance be deemed a pledge of the Mortgage Loans and
related property by the Seller to the Purchaser to secure a debt or other
obligation of the Seller. However, in the event that, notwithstanding the intent
of the parties, the Mortgage Loans or any related property are held to be the
property of the Seller, or if for any other reason this Agreement is held or
deemed to create a security interest in the Mortgage Loans or any related
property, then:

            (i) this Agreement shall be deemed to be a security agreement; and

             (ii) the conveyance provided for in this Section 2 shall be deemed
      to be a grant by the Seller to the Purchaser of a security interest in all
      of the Seller's right, title, and interest, whether now owned or hereafter
      acquired, in and to:

                  (A) All accounts, 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
            following property: the Mortgage Loans identified on the Mortgage
            Loan Schedule, including the related Mortgage Notes, Mortgages,
            security agreements, and title, hazard and other insurance policies,
            all distributions with respect thereto payable after the Cut-Off
            Date, all substitute or replacement Mortgage Loans and all
            distributions with respect thereto, and the Mortgage Files;

                   (B) All accounts, general intangibles, chattel paper,
            instruments, documents, money, deposit accounts, certificates of
            deposit, goods, letters of credit, advices of credit, investment
            property and other rights 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 (A) above (including any accrued discount realized on
            liquidation of any investment purchased at a discount); and

                  (C) All cash and non-cash proceeds of the collateral described
            in clauses (A) and (B) above.

            The possession by the Purchaser or its designee of the Mortgage
Notes, the Mortgages, 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 for purposes of perfecting the security interest pursuant to the
Uniform Commercial Code (including, without limitation, Sections 9-305 and 9-115
thereof) as in force in the relevant jurisdiction. Notwithstanding the
foregoing, the Seller makes no representation or warranty as to the perfection
of any such security interest.

            Notifications to Persons holding such property, and acknowledgments,
receipts, or confirmations from persons holding such property, shall be deemed
to be notifications to, or acknowledgments, receipts or confirmations from,
securities intermediaries, bailees or agents of, or Persons holding for, the
Purchaser or its designee, as applicable, for the purpose of perfecting such
security interest under applicable law.

            The Seller shall, to the extent consistent with this Agreement, take
such reasonable actions as may be necessary to ensure that, if this Agreement
were deemed to create a security interest in the property described above, such
security interest would be deemed to be a perfected security interest of first
priority under applicable law and will be maintained as such throughout the term
of the Agreement. In such case, the Seller shall file all filings necessary to
maintain the effectiveness of any original filings necessary under the Uniform
Commercial Code as in effect in any jurisdiction to perfect such security
interest in such property. In connection herewith, the Purchaser 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.

            Notwithstanding anything to the contrary contained herein, and
subject to Section 2(a), the Purchaser shall not be required to purchase any
Mortgage Loan as to which any Mortgage Note (endorsed as described in clause (a)
above) or lost note affidavit and indemnity required to be delivered to or on
behalf of the Trustee or the applicable Master Servicer pursuant to this Section
2 on or before the Closing Date is not so delivered, or is not properly executed
or is defective on its face, and the Purchaser's acceptance of the related
Mortgage Loan on the Closing Date shall in no way constitute a waiver of such
omission or defect or of the Purchaser's or its successors' and assigns' rights
in respect thereof pursuant to Section 5.

            Section 3. Examination of Mortgage Files and Due Diligence Review.
The Seller shall (i) deliver to the Purchaser on or before the Closing Date a
diskette acceptable to the Purchaser that contains such information about the
Mortgage Loans as may be reasonably requested by the Purchaser, (ii) deliver to
the Purchaser investor files (collectively the "Collateral Information") with
respect to the assets proposed to be included in the Mortgage Pool and made
available at the Purchaser's headquarters in New York, and (iii) otherwise
cooperate fully with the Purchaser in its examination of the credit files,
underwriting documentation and Mortgage Files for the Mortgage Loans and its due
diligence review of the Mortgage Loans. The fact that the Purchaser has
conducted or has failed to conduct any partial or complete examination of the
credit files, underwriting documentation or Mortgage Files for the Mortgage
Loans shall not affect the right of the Purchaser or the Trustee to cause the
Seller to cure any Material Document Defect or Material Breach (each as defined
below), or to repurchase or replace the defective Mortgage Loans pursuant to
Section 5 of this Agreement.

            On or prior to the Closing Date, the Seller shall allow
representatives of any of the Purchaser, each Underwriter, the Initial
Purchaser, the Trustee, the applicable Special Servicer and each Rating Agency
to examine and audit all books, records and files pertaining to the Mortgage
Loans, the Seller's underwriting procedures and the Seller's ability to perform
or observe all of the terms, covenants and conditions of this Agreement. Such
examinations and audits shall take place at one or more offices of the Seller
during normal business hours and shall not be conducted in a manner that is
disruptive to the Seller's normal business operations upon reasonable prior
advance notice. In the course of such examinations and audits, the Seller will
make available to such representatives of any of the Purchaser, each
Underwriter, the Initial Purchaser, the Trustee, the applicable Special Servicer
and each Rating Agency reasonably adequate facilities, as well as the assistance
of a sufficient number of knowledgeable and responsible individuals who are
familiar with the Mortgage Loans and the terms of this Agreement, and the Seller
shall cooperate fully with any such examination and audit in all material
respects. On or prior to the Closing Date, the Seller shall provide the
Purchaser with all material information regarding the Seller's financial
condition and access to knowledgeable financial or accounting officers for the
purpose of answering questions with respect to the Seller's financial condition,
financial statements as provided to the Purchaser or other developments
affecting the Seller's ability to consummate the transactions contemplated
hereby or otherwise affecting the Seller in any material respect. Within 45 days
after the Closing Date, the Seller shall provide the applicable Master Servicer
or Primary Servicer, if applicable, with any additional information identified
by the applicable Master Servicer or Primary Servicer, if applicable, as
necessary to complete the CMSA Property File, to the extent that such
information is available.

            The Purchaser may exercise any of its rights hereunder through one
or more designees or agents; provided the Purchaser has provided the Seller with
prior notice of the identity of such designee or agent.

            The Purchaser shall keep confidential any information regarding the
Seller and the Mortgage Loans that has been delivered into the Purchaser's
possession and that is not otherwise publicly available; provided, however, that
such information shall not be kept confidential (and the right to require
confidentiality under any confidentiality agreement is hereby waived) to the
extent such information is required to be included in the Memorandum or the
Prospectus Supplement or the Purchaser is required by law or court order to
disclose such information. If the Purchaser is required to disclose in the
Memorandum or the Prospectus Supplement confidential information regarding the
Seller as described in the preceding sentence, the Purchaser shall provide to
the Seller a copy of the proposed form of such disclosure prior to making such
disclosure and the Seller shall promptly, and in any event within two Business
Days, notify the Purchaser of any inaccuracies therein, in which case the
Purchaser shall modify such form in a manner that corrects such inaccuracies. If
the Purchaser is required by law or court order to disclose confidential
information regarding the Seller as described in the second preceding sentence,
the Purchaser shall notify the Seller and cooperate in the Seller's efforts to
obtain a protective order or other reasonable assurance that confidential
treatment will be accorded such information and, if in the absence of a
protective order or such assurance, the Purchaser is compelled as a matter of
law to disclose such information, the Purchaser shall, prior to making such
disclosure, advise and consult with the Seller and its counsel as to such
disclosure and the nature and wording of such disclosure and the Purchaser shall
use reasonable efforts to obtain confidential treatment therefor.
Notwithstanding the foregoing, if reasonably advised by counsel that the
Purchaser is required by a regulatory agency or court order to make such
disclosure immediately, then the Purchaser shall be permitted to make such
disclosure without prior review by the Seller.

            Section 4. Representations and Warranties of the Seller and the
Purchaser.

            (a) To induce the Purchaser to enter into this Agreement, the Seller
hereby makes for the benefit of the Purchaser and its assigns with respect to
each Mortgage Loan as of the date hereof (or as of such other date specifically
set forth in the particular representation and warranty) each of the
representations and warranties set forth on Exhibit 2 hereto, except as
otherwise set forth on Schedule A attached hereto, and hereby further represents
and warrants to the Purchaser as of the date hereof that:

            (i) The Seller is duly organized and is validly existing as a
      corporation in good standing under the laws of New York. The Seller has
      the requisite power and authority and legal right to own the Mortgage
      Loans and to transfer and convey the Mortgage Loans to the Purchaser and
      has the requisite power and authority to execute and deliver, engage in
      the transactions contemplated by, and perform and observe the terms and
      conditions of, this Agreement.

            (ii) This Agreement has been duly and validly authorized, executed
      and delivered by the Seller, and assuming the due authorization, execution
      and delivery hereof by the Purchaser, this Agreement constitutes the
      valid, legal and binding agreement of the Seller, enforceable 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, (C) general equity principles (regardless of whether
      such enforcement is considered in a proceeding in equity or at law) or (D)
      public policy considerations underlying the securities laws, to the extent
      that such public policy considerations limit the enforceability of the
      provisions of this Agreement that purport to provide indemnification from
      liabilities under applicable securities laws.

            (iii) 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 of or compliance by the Seller with this Agreement, or the
      consummation by the Seller of any transaction contemplated hereby, other
      than (1) such qualifications as may be required under state securities or
      blue sky laws, (2) the filing or recording of financing statements,
      instruments of assignment and other similar documents necessary in
      connection with the Seller's sale of the Mortgage Loans to the Purchaser,
      (3) such consents, approvals, authorizations, qualifications,
      registrations, filings or notices as have been obtained and (4) where the
      lack of such consent, approval, authorization, qualification,
      registration, filing or notice would not have a material adverse effect on
      the performance by the Seller under this Agreement.

            (iv) Neither the transfer of the Mortgage Loans to the Purchaser,
       nor the execution, delivery or performance of this Agreement by the
      Seller, conflicts or will conflict with, results or will result in a
      breach of, or constitutes or will constitute a default under (A) any term
      or provision of the Seller's articles of organization or by-laws, (B) any
      term or provision of any material agreement, contract, instrument or
      indenture to which the Seller is a party or by which it or any of its
      assets is bound or results in the creation or imposition of any lien,
      charge or encumbrance upon any of its property pursuant to the terms of
      any such indenture, mortgage, contract or other instrument, other than
      pursuant to this Agreement, or (C) after giving effect to the consents or
       taking of the actions contemplated in subsection (iii), any law, rule,
      regulation, order, judgment, writ, injunction or decree of any court or
      governmental authority having jurisdiction over the Seller or its assets,
      except where in any of the instances contemplated by clauses (B) or (C)
      above, any conflict, breach or default, or creation or imposition of any
      lien, charge or encumbrance, will not have a material adverse effect on
      the consummation of the transactions contemplated hereby by the Seller or
      materially and adversely affect its ability to perform its obligations and
      duties hereunder or result in any material adverse change in the business,
      operations, financial condition, properties or assets of the Seller, or in
      any material impairment of the right or ability of the Seller to carry on
      its business substantially as now conducted.

            (v) There are no actions or proceedings against, or investigations
      of, the Seller pending or, to the Seller's knowledge, threatened in
      writing against the Seller before any court, administrative agency or
      other tribunal, the outcome of which could reasonably be expected to
      materially and adversely affect the transfer of the Mortgage Loans to the
      Purchaser or the execution or delivery by, or enforceability against, the
      Seller of this Agreement or have an effect on the financial condition of
      the Seller that would materially and adversely affect the ability of the
      Seller to perform its obligations under this Agreement.

            (vi) On the Closing Date, the sale of the Mortgage Loans pursuant to
      this Agreement will effect a transfer by the Seller of all of its right,
      title and interest in and to the Mortgage Loans to the Purchaser.

            (vii) To the Seller's knowledge, the Loan Seller Information (as
      defined in that certain indemnification agreement, dated as of March 22,
      2007, between the Seller, the Purchaser, the Underwriters and the Initial
      Purchaser (the "Indemnification Agreement")) contained in the Disclosure
      Information (as defined in the Indemnification Agreement), the Memorandum
      and the Prospectus Supplement (i) does not contain any untrue statement of
      a material fact or omit to state a material fact necessary to make the
      statements therein, in the light of the circumstances under which they
      were made, not misleading and (ii) (other than the Memorandum) complies
      with the requirements of and contains all of the applicable information
      required by Regulation AB (as defined in the Indemnification Agreement).

            To induce the Purchaser to enter into this Agreement, the Seller
hereby covenants that the foregoing representations and warranties and those set
forth on Exhibit 2 hereto will be true and correct in all material respects on
and as of the Closing Date with the same effect as if made on the Closing Date,
provided that any representations and warranties made as of a specified date
shall be true and correct in all material respects as of such specified date.

            Each of the representations, warranties and covenants made by the
Seller pursuant to this Section 4(a) shall survive the sale of the Mortgage
Loans and shall continue in full force and effect notwithstanding any
restrictive or qualified endorsement on the Mortgage Notes.

            (b) To induce the Seller to enter into this Agreement, the Purchaser
hereby represents and warrants to the Seller as of the date hereof:

            (i) The Purchaser is a corporation duly organized, validly existing,
      and in good standing under the laws of the State of Delaware with full
      power and authority to carry on its business as presently conducted by it.

            (ii) The Purchaser has full power and authority to acquire the
      Mortgage Loans, to execute and deliver this Agreement and to enter into
      and consummate all transactions contemplated by this Agreement. The
      Purchaser has duly and validly authorized the execution, delivery and
      performance of this Agreement and has duly and validly executed and
      delivered this Agreement. This Agreement, assuming due authorization,
      execution and delivery by the Seller, constitutes the valid and binding
      obligation of the Purchaser, enforceable against it in accordance with its
      terms, except as such enforceability may be limited by bankruptcy,
      insolvency, reorganization, moratorium and other similar laws affecting
      the enforcement of creditors' rights generally and by general principles
      of equity, regardless of whether such enforcement is considered in a
      proceeding in equity or at law.

            (iii) 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 of or compliance by the Purchaser with this Agreement, or the
      consummation by the Purchaser of any transaction contemplated hereby that
      has not been obtained or made by the Purchaser.

            (iv) Neither the purchase of the Mortgage Loans nor the execution,
      delivery and performance of this Agreement by the Purchaser will violate
      the Purchaser's certificate of incorporation or by-laws or constitute a
      default (or an event that, with notice or lapse of time or both, would
      constitute a default) under, or result in a breach of, any material
      agreement, contract, instrument or indenture to which the Purchaser is a
      party or that may be applicable to the Purchaser or its assets.

            (v) The Purchaser's execution and delivery of this Agreement and its
      performance and compliance with the terms of this Agreement will not
      constitute a violation of, any law, rule, writ, injunction, order or
      decree of any court, or order or regulation of any federal, state or
      municipal government agency having jurisdiction over the Purchaser or its
      assets, which violation could materially and adversely affect the
      condition (financial or otherwise) or the operation of the Purchaser or
      its assets or could materially and adversely affect its ability to perform
      its obligations and duties hereunder.

            (vi) There are no actions or proceedings against, or investigations
      of, the Purchaser pending or, to the Purchaser's knowledge, threatened
      against the Purchaser before any court, administrative agency or other
      tribunal, the outcome of which could reasonably be expected to adversely
      affect the transfer of the Mortgage Loans, the issuance of the
      Certificates, the execution, delivery or enforceability of this Agreement
      or have an effect on the financial condition of the Purchaser that would
      materially and adversely affect the ability of the Purchaser to perform
      its obligation under this Agreement.

            (vii) The Purchaser has not dealt with any broker, investment
      banker, agent or other person, other than the Seller, the Underwriters,
      the Initial Purchaser and their respective affiliates, that may be
      entitled to any commission or compensation in connection with the sale of
      the Mortgage Loans or consummation of any of the transactions contemplated
      hereby.

            To induce the Seller to enter into this Agreement, the Purchaser
hereby covenants that the foregoing representations and warranties will be true
and correct in all material respects on and as of the Closing Date with the same
effect as if made on the Closing Date.

            Each of the representations and warranties made by the Purchaser
pursuant to this Section 4(b) shall survive the purchase of the Mortgage Loans.

            Section 5. Remedies Upon Breach of Representations and Warranties
Made by the Seller.

            (a) It is hereby acknowledged that the Seller shall make for the
benefit of the Trustee on behalf of the holders of the Certificates, whether
directly or by way of the Purchaser's assignment of its rights hereunder to the
Trustee, the representations and warranties set forth on Exhibit 2 hereto (each
as of the date hereof unless otherwise specified).

            (b) It is hereby further acknowledged that if any document required
to be delivered to the Trustee pursuant to Section 2 is not delivered as and
when required (and including the expiration of any grace or cure period), is not
properly executed or is defective on its face, or if there is a breach of any of
the representations and warranties required to be made by the Seller regarding
the characteristics of the Mortgage Loans and/or the related Mortgaged
Properties as set forth in Exhibit 2 hereto, and in either case such defect or
breach, either (i) materially and adversely affects the interests of the holders
of the Certificates in the related Mortgage Loan, or (ii) both (A) the document
defect or breach materially and adversely affects the value of the Mortgage Loan
and (B) the Mortgage Loan is a Specially Serviced Mortgage Loan or Rehabilitated
Mortgage Loan (such a document defect described in the preceding clause (i) or
(ii), a "Material Document Defect" and such a breach described in the preceding
clause (i) or (ii) a "Material Breach"), the party discovering such Material
Document Defect or Material Breach shall promptly notify, in writing, the other
party; provided that any breach of the representation and warranty contained in
paragraph (38) of such Exhibit 2 shall constitute a Material Breach only if such
prepayment premium or yield maintenance charge is not deemed "customary" for
commercial mortgage loans as evidenced by (i) an opinion of tax counsel to such
effect or (ii) a determination by the Internal Revenue Service that such
provision is not customary. Promptly (but in any event within three Business
Days) upon becoming aware of any such Material Document Defect or Material
Breach, the applicable Master Servicer shall, and the applicable Special
Servicer may, request that the Seller, not later than 90 days from the Seller's
receipt of the notice of such Material Document Defect or Material Breach, cure
such Material Document Defect or Material Breach, as the case may be, in all
material respects; provided, however, that if such Material Document Defect or
Material Breach, as the case may be, cannot be corrected or cured in all
material respects within such 90-day period, and such Material Document Defect
or Material Breach would not cause the Mortgage Loan to be other than a
"qualified mortgage" (as defined in the Code), but the Seller is diligently
attempting to effect such correction or cure, as certified by the Seller in an
Officer's Certificate delivered to the Trustee, then the cure period will be
extended for an additional 90 days unless, solely in the case of a Material
Document Defect, (x) the Mortgage Loan is, at the end of the initial 90-day
period, a Specially Serviced Mortgage Loan and a Servicing Transfer Event has
occurred as a result of a monetary default or as described in clause (ii) or
clause (v) of the definition of "Servicing Transfer Event" in the Pooling and
Servicing Agreement and (y) the Material Document Defect was identified in a
certification delivered to the Seller by the Trustee pursuant to Section 2.2 of
the Pooling and Servicing Agreement not less than 90 days prior to the delivery
of the notice of such Material Document Defect. The parties acknowledge that
neither delivery of a certification or schedule of exceptions to the Seller
pursuant to Section 2.2 of the Pooling and Servicing Agreement or otherwise nor
possession of such certification or schedule by the Seller shall, in and of
itself, constitute delivery of notice of any Material Document Defect or
knowledge or awareness by the Seller of any Material Document Defect listed
therein.

            The Seller hereby covenants and agrees that, if any such Material
Document Defect or Material Breach cannot be corrected or cured in all material
aspects within the above cure periods, the Seller shall, on or before the
termination of such cure periods, either (i) repurchase the affected Mortgage
Loan or REO Mortgage Loan from the Purchaser or its assignee at the Purchase
Price as defined in the Pooling and Servicing Agreement, or (ii) if within the
two-year period commencing on the Closing Date, at its option replace, without
recourse, any Mortgage Loan or REO Mortgage Loan to which such defect relates
with a Qualifying Substitute Mortgage Loan. If such Material Document Defect or
Material Breach would cause the Mortgage Loan to be other than a "qualified
mortgage" (as defined in the Code), then notwithstanding the previous sentence,
such repurchase or substitution must occur within 90 days from the earlier of
the date the Seller discovered or was notified of the breach or defect. The
Seller agrees that any substitution shall be completed in accordance with the
terms and conditions of the Pooling and Servicing Agreement.

            If (i) a Mortgage Loan is to be repurchased or replaced in
connection with a Material Document Defect or Material Breach as contemplated
above, (ii) such Mortgage Loan is cross-collateralized and cross-defaulted with
one or more other Mortgage Loans in the Trust and (iii) the applicable document
defect or breach does not constitute a Material Document Defect or Material
Breach, as the case may be, as to such other Mortgage Loans (without regard to
this paragraph), then the applicable document defect or breach (as the case may
be) shall be deemed to constitute a Material Document Defect or Material Breach,
as the case may be, as to each such other Mortgage Loan for purposes of the
above provisions, and the Seller shall be obligated to repurchase or replace
each such other Mortgage Loan in accordance with the provisions above, unless,
in the case of such breach or document defect, both of the following conditions
would be satisfied if the Seller were to repurchase or replace only those
Mortgage Loans as to which a Material Breach had occurred without regard to this
paragraph (the "Affected Loan(s)"): (1) the debt service coverage ratio for all
such other Mortgage Loans (excluding the Affected Loan(s)) for the four calendar
quarters immediately preceding the repurchase or replacement (determined as
provided in the definition of Debt Service Coverage Ratio in the Pooling and
Servicing Agreement, except that net cash flow for such four calendar quarters,
rather than year-end, shall be used) is equal to the greater of (x) the debt
service coverage ratio for all such Mortgage Loans (including the Affected
Loan(s)) set forth under the heading "NCF DSCR" in Appendix II to the Final
Prospectus Supplement and (y) 1.25x, and (2) the Loan-to-Value Ratio for all
such other Mortgage Loans (excluding the Affected Loan(s)) is not greater than
the lesser of (x) the current loan-to-value ratio for all such Mortgage Loans
(including the Affected Loan(s)) set forth under the heading "Cut-Off Date LTV"
in Appendix II to the Final Prospectus Supplement and (y) 75%. The determination
of the Master Servicer as to whether either of the conditions set forth above
has been satisfied shall be conclusive and binding in the absence of manifest
error. The Master Servicer will be entitled to cause, or direct the Seller to
cause, to be delivered to the Master Servicer at the Seller's expense (i) an
Appraisal of any or all of the related Mortgaged Properties for purposes of
determining whether the condition set forth in clause (2) above has been
satisfied, in each case at the expense of the Seller if the scope and cost of
the Appraisal is approved by the Seller (such approval not to be unreasonably
withheld) and (ii) an Opinion of Counsel that not requiring the repurchase of
each such Cross-Collateralized Loan will not result in an Adverse REMIC Event.

             With respect to any Mortgage Loan that is cross-defaulted and/or
cross-collateralized with any other Mortgage Loan conveyed hereunder, to the
extent that the Seller is required to repurchase or substitute for such Mortgage
Loan (each, a "Repurchased Loan") in the manner prescribed above while the
Trustee (as assignee of the Purchaser) continues to hold any other Mortgage Loan
that is cross-collateralized and/or cross-defaulted (each, a
"Cross-Collateralized Loan") with such Repurchased Loan, the Seller and the
Purchaser hereby agree to modify, upon such repurchase or substitution, the
related Mortgage Loan documents in a manner such that such affected Repurchased
Loan, on the one hand, and any related Crossed-Collateralized Loans held by the
Trustee, on the other, would no longer be cross-defaulted or
cross-collateralized with one another; provided that the Seller shall have
furnished the Trustee, at the expense of the Seller, a nondisqualification
opinion that such modification shall not cause an Adverse REMIC Event; provided,
further, that if such nondisqualification opinion cannot be furnished, the
Seller and the Purchaser agreed that such repurchase or substitution of only the
Repurchased Loan, notwithstanding anything to the contrary herein, shall not be
permitted and the Seller shall repurchase or substitute for the Repurchased Loan
and all related Crossed-Collateralized Loans. Any reserve or other cash
collateral or letters of credit securing the Cross-Collateralized 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. The Mortgagors set forth on Schedule B
hereto are intended third-party beneficiaries of the provisions set forth in
this paragraph and the preceding paragraph. The provisions of this paragraph and
the preceding paragraph may not be modified with respect to any Mortgage Loan
without the related Mortgagor's consent.

            Upon occurrence (and after any applicable cure or grace period), any
of the following document defects shall be conclusively presumed materially and
adversely to affect the interests of Certificateholders in a Mortgage Loan and
be a Material Document Defect: (i) the absence from the Mortgage File of the
original signed Mortgage Note, unless the Mortgage File contains a signed lost
note affidavit and indemnity and a copy of the Mortgage Note; (ii) the absence
from the Mortgage File of the item called for by paragraph (b) of the definition
of Mortgage File; or (iii) the absence from the Mortgage File of the item called
for by paragraph (h) of the definition of Mortgage File. If any of the foregoing
Material Document Defects is discovered by the Custodian (or the Trustee if
there is no Custodian), the Trustee (or as set forth in Section 2.3(a) of the
Pooling and Servicing Agreement, the applicable Master Servicer) will take the
steps described elsewhere in this Section, including the giving of notices to
the Rating Agencies and the parties hereto and making demand upon the Seller for
the cure of the Material Document Defect or repurchase or replacement of the
related Mortgage Loan.

            If the Seller disputes that a Material Document Defect or Material
Breach exists with respect to a Mortgage Loan or otherwise refuses (i) to effect
a correction or cure of such Material Document Defect or Material Breach, (ii)
to repurchase the Affected Loan from the Trust or (iii) to replace such Mortgage
Loan with a Qualifying Substitute Mortgage Loan, then provided that (x) the
period of time provided for the Seller to correct, repurchase or cure has
expired and (y) the Mortgage Loan is then in default and is then a Specially
Serviced Mortgage Loan, the applicable Special Servicer may, subject to the
Servicing Standard, modify, work-out or foreclose, sell or otherwise liquidate
(or permit the liquidation of) the Mortgage Loan pursuant to Section 9.5,
Section 9.12, Section 9.15 and Section 9.36, as applicable, of the Pooling and
Servicing Agreement, while pursuing the repurchase claim. The Seller
acknowledges and agrees that any modification of the Mortgage Loan pursuant to
such a work-out shall not constitute a defense to any repurchase claim nor shall
such modification or work-out change the Purchase Price due from the Seller for
any repurchase claim. Any sale of the Mortgage Loan, or foreclosure upon such
Mortgage Loan and sale of the REO Property, to a Person other than the Seller
shall be without (i) recourse of any kind (either express or implied) by such
Person against the Seller and (ii) representation or warranty of any kind
(either express or implied) by the Seller to or for the benefit of such Person.

            The fact that a Material Document Defect or Material Breach is not
discovered until after foreclosure (but in all instances prior to the sale of
the related REO Property or Mortgage Loan) shall not prejudice any claim against
the Seller for repurchase of the REO Mortgage Loan or REO Property. In such an
event, the applicable Master Servicer or Special Servicer, as applicable, shall
be required to notify the Seller of the discovery of the Material Document
Defect or Material Breach and the Seller shall be required to follow the
procedures set forth in this Agreement to correct or cure such Material Document
Defect or Material Breach or purchase the REO Property at the Purchase Price. If
the Seller fails to correct or cure the Material Document Defect or Material
Breach or purchase the REO Property, then the provisions above regarding notice
of offers related to such REO Property and the Seller's right to purchase such
REO Property shall apply. If a court of competent jurisdiction issues a final
order that the Seller is or was obligated to repurchase the related Mortgage
Loan or REO Mortgage Loan or the Seller otherwise accepts liability, then, after
the expiration of any applicable appeal period, but in no event later than the
termination of the Trust pursuant to Section 9.30 of the Pooling and Servicing
Agreement, the Seller will be obligated to pay to the Trust the difference
between any Liquidation Proceeds received upon such liquidation (including those
arising from any sale to the Seller) and the Purchase Price; provided that the
prevailing party in such action shall be entitled to recover all costs, fees and
expenses (including reasonable attorneys' fees) related thereto.

            In connection with any liquidation or sale of a Mortgage Loan or REO
Property as described above, the applicable Special Servicer will not receive a
Liquidation Fee in connection with such liquidation or sale or any portion of
the Work-Out Fee that accrues after the Seller receives notice of a Material
Document Defect or Material Breach until a final determination has been made, as
set forth in the prior paragraph, as to whether the Seller is or was obligated
to repurchase such related Mortgage Loan or REO Property. Upon such
determination, the applicable Special Servicer will be entitled: (i) with
respect to a determination that the Seller is or was obligated to repurchase, to
collect a Liquidation Fee, if due in accordance with the definition thereof,
based upon the full Purchase Price of the related Mortgage Loan or REO property,
with such Liquidation Fee payable by the Seller or (ii) with respect to a
determination that Seller is not or was not obligated to repurchase (or the
Trust decides that it will no longer pursue a claim against the Seller for
repurchase), (A) to collect a Liquidation Fee based upon the Liquidation
Proceeds as received upon the actual sale or liquidation of such Mortgage Loan
or REO Property, and (B) to collect any accrued and unpaid Work-Out Fee, based
on amounts that were collected for as long as the related Mortgage Loan was a
Rehabilitated Mortgage Loan, in each case with such amount to be paid from
amounts in the Certificate Account.

            The obligations of the Seller set forth in this Section 5(b) to cure
a Material Document Defect or a Material Breach or repurchase or replace a
defective Mortgage Loan constitute the sole remedies of the Purchaser or its
assignees with respect to a Material Document Defect or Material Breach in
respect of an outstanding Mortgage Loan; provided, that this limitation shall
not in any way limit the Purchaser's rights or remedies upon breach of any other
representation or warranty or covenant by the Seller set forth in this Agreement
(other than those set forth in Exhibit 2).

            Notwithstanding the foregoing, in the event that there is a breach
of the representation and warranty set forth in paragraph 41 of Exhibit 2
attached hereto because the underlying loan documents do not provide for the
payment by the Mortgagor of reasonable costs and expenses associated with the
defeasance or assumption of a Mortgage Loan by the Mortgagor, the Seller hereby
covenants and agrees to pay such reasonable costs and expenses, to the extent an
amount is due and not paid by the related Mortgagor. The parties hereto
acknowledge that the payment of such reasonable costs and expenses shall be the
Seller's sole obligation with respect to the breaches discussed in the previous
sentence. The Seller shall have no obligation to pay for any of the foregoing
costs if the applicable Mortgagor has an obligation to pay for such costs.

             The Seller hereby agrees that it will pay for any expense incurred
by the applicable Master Servicer or the applicable Special Servicer, as
applicable, in connection with modifying a Mortgage Loan pursuant to Section 2.3
of the Pooling and Servicing Agreement in order for such Mortgage Loan to be a
"qualified substitute mortgage loan" within the meaning of the Treasury
Regulations promulgated under the Code. Upon a breach of the representation and
warranty set forth in paragraph 37 of Exhibit 2 attached hereto, if such
Mortgage Loan is modified so that it becomes a "qualified substitute mortgage
loan", such breach will be cured and the Seller will not be obligated to
repurchase or otherwise remedy such breach.

            (c) The Pooling and Servicing Agreement shall provide that the
Trustee (or the applicable Master Servicer or the applicable Special Servicer on
its behalf) shall give written notice within three Business Days to the Seller
of its discovery of any Material Document Defect or Material Breach and prompt
written notice to the Seller in the event that any Mortgage Loan becomes a
Specially Serviced Mortgage Loan (as defined in the Pooling and Servicing
Agreement).

            (d) If the Seller repurchases any Mortgage Loan pursuant to this
Section 5, the Purchaser or its assignee, following receipt by the Trustee of
the Purchase Price therefor, promptly shall deliver or cause to be delivered to
the Seller all Mortgage Loan documents with respect to such Mortgage Loan, and
each document that constitutes a part of the Mortgage File that was endorsed or
assigned to the Trustee shall be endorsed and assigned to the Seller in the same
manner such that the Seller shall be vested with legal and beneficial title to
such Mortgage Loan, in each case without recourse, including any property
acquired in respect of such Mortgage Loan or proceeds of any insurance policies
with respect thereto.

            Section 6. Closing. The closing of the sale of the Mortgage Loans
shall be held at the offices of Cadwalader, Wickersham & Taft LLP, One World
Financial Center, New York, NY 10281 at 9:00 a.m., New York time, on the Closing
