Ladies and Gentlemen:

      Morgan Stanley Capital I Inc., a Delaware corporation (the "Depositor"),
proposes to cause the issuance of, and to sell to Morgan Stanley & Co.
Incorporated and Bear, Stearns & Co. Inc. (together, the "Underwriters"), the
Commercial Mortgage Pass-Through Certificates identified in Schedule I hereto
(the "Certificates") pursuant to this Underwriting Agreement, dated December 20,
2007 (this "Agreement"), between the Depositor and the Underwriters. The
Certificates will evidence beneficial ownership interests in a trust fund (the
"Trust Fund") to be formed by the Depositor and consisting primarily of a
segregated pool (the "Mortgage Pool") of multifamily, manufactured housing
community and commercial mortgage loans (the "Mortgage Loans").

      Certain of the Mortgage Loans (the "MSMCH Mortgage Loans") will be
acquired by the Depositor from Morgan Stanley Mortgage Capital Holdings LLC
("MSMCH") pursuant to the mortgage loan purchase agreement, dated December 20,
2007 (the "MSMCH Mortgage Loan Purchase Agreement") between the Depositor and
MSMCH. Certain of the Mortgage Loans (the "Nomura Mortgage Loans") will be
acquired by the Depositor from Nomura Credit & Capital, Inc. ("Nomura") pursuant
to the mortgage loan purchase agreement, dated December 20, 2007 (the "Nomura
Mortgage Loan Purchase Agreement"), between the Depositor and Nomura. Certain of
the Mortgage Loans (the "AMAC Mortgage Loans") will be acquired by the Depositor
from American Mortgage Acceptance Company ("AMAC" and, together with MSMCH and
Nomura, the "Mortgage Loan Sellers") pursuant to the mortgage loan purchase
agreement, dated December 20, 2007 (the "AMAC Mortgage Loan Purchase Agreement"
and, together with the MSMCH Mortgage Loan Purchase Agreement and the AMAC
Mortgage Loan Purchase Agreement, the "Mortgage Loan Purchase Agreements")
between the Depositor and AMAC.

      The Trust is to be created, and the Certificates are to be issued, under a
pooling and servicing agreement, dated as of December 1, 2007 (the "Pooling and
Servicing Agreement"), between the Depositor, as depositor, Wachovia Bank,
National Association, as master servicer (the "Master Servicer"), Centerline
Servicing Inc., as special servicer (the "Special Servicer"), Wells Fargo Bank,
National Association, as trustee (in such capacity, the "Trustee"), custodian,
paying agent (in such capacity, the "Paying Agent"), certificate registrar and
authenticating agent.

      Capitalized terms used herein, but not otherwise defined herein shall have
the meanings set forth in the Mortgage Loan Purchase Agreements.

      The Depositor has filed with the Securities and Exchange Commission (the
"Commission") a registration statement (No. 333-143623) on Form S-3 for the
registration of the Certificates under the Securities Act of 1933, as amended
(the "1933 Act"), which registration statement has become effective. The
Depositor proposes to file with the Commission pursuant to Rule 424(b) under the
1933 Act a supplement to the form of prospectus included in such registration
statement relating to the Certificates and the plan of distribution thereof.
Such registration statement, including the exhibits thereto, and information
that is contained in the Prospectus (as defined below) and is deemed to be part
of and included in such registration statement as it may have been amended or
supplemented at the date of the Prospectus, is hereinafter referred to as the
"Registration Statement"; the prospectus first required to be filed to satisfy
the condition set forth in Rule 172(c) and pursuant to Rule 424(b) under the
1933 Act, is hereinafter referred to as the "Base Prospectus"; such form of
supplement to the Base Prospectus relating to the Certificates, in the form
first required to be filed to satisfy the condition set forth in Rule 172(c) and
pursuant to Rule 424(b) under the 1933 Act (including the Base Prospectus as so
supplemented) is hereinafter referred to as the "Prospectus Supplement"; and the
Base Prospectus and the Prospectus Supplement, together, are hereinafter
referred to as the "Prospectus".

      At or prior to the time when sales to purchasers of the Certificates were
first made, which was approximately 2:30 p.m. on December 20, 2007 (the "Time of
Sale"), the Depositor had prepared the following information (collectively, the
"Time of Sale Information"): the Depositor's Free Writing Prospectus dated
December 13, 2007 (the cover page of which is attached hereto as Annex A) to
accompany the Depositor's Prospectus dated December 12, 2007, the Depositor's
Prospectus dated December 12, 2007, the Term Sheet dated December 13, 2007,
relating to the Certificates, each "free-writing prospectus" (as defined
pursuant to Rule 405 under the 1933 Act) (a "Free Writing Prospectus") the first
page of each of which is attached as Annex B hereto and the pricing information
annex attached hereto as Annex C. If, subsequent to the date of this Agreement,
the Depositor and the Underwriters determine that such information included an
untrue statement of material fact or omitted to state a material fact necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading and terminate their old purchase contracts
and enter into new purchase contracts with purchasers of the Certificates, then
"Time of Sale Information" will refer to the information conveyed to purchasers
at the time of entry into the first such new purchase contract, including any
information that corrects such material misstatements or omissions ("Corrective
Information") and "Time of Sale" will refer to the time and date on which such
new purchase contracts were entered into.


                                        2

of the 1933 Act and the rules and regulations thereunder (the "1933 Act
Regulations"); and the information in the Registration Statement, as of the
Effective Date, did not contain any untrue statement of a material fact and did
not omit to state any material fact required to be stated therein or necessary

supplement thereto in reliance upon and in conformity with information furnished
in writing to the Depositor by any Underwriter on behalf of itself or the other
Underwriters specifically for use in connection with the preparation of the
Prospectus or any revision or amendment thereof or supplement thereto (the
"Underwriter Information"), or (B) any information contained in or omitted from
the portions of the Prospectus Supplement for which the Mortgage Loan Sellers

or warranties regarding untrue statements or omissions in the portions of the
Prospectus Supplement under the heading "Yield, Prepayment and Maturity
Considerations" that arise out of or are based upon untrue statements or
omissions in the Mortgage Loan Seller Information. The Underwriter Information
shall consist of the second, fourth and ninth paragraphs of the section of the
Prospectus Supplement entitled "Plan of Distribution" and the first two
sentences of the last paragraph on the cover page of the Prospectus Supplement.

            (ii)    The Time of Sale Information, at the Time of Sale, did not,

fact or omit to state a material fact necessary in order to make the statements

            (iii)   Other than the Prospectus, the Depositor (including its
agents and representatives other than the Underwriters in their capacity as
such) has not made, used,


                                        3

prepared, authorized, approved or referred to and will not make, use, prepare,
authorize, approve or refer to any "written communication" (as defined in Rule
405 under the 1933 Act) that constitutes an offer to sell or solicitation of an
offer to buy the Certificates other than (i) any document not constituting a
prospectus pursuant to Section 2(a)(10)(a) of the 1933 Act or Rule 134 under the
1933 Act, (ii) the Time of Sale Information, and (iii) each other written
communication of the Depositor or its agents and representatives approved by the
Underwriters either in writing in advance or in any other manner mutually agreed
to by the Underwriters and the Depositor (each such communication referred to in
clause (ii) and this clause (iii) constituting an "issuer free writing
prospectus", as defined in Rule 433(h) under the 1933 Act, being referred to as
an "Issuer Free Writing Prospectus"). Each such Issuer Free Writing Prospectus
complied or, if used after the date hereof, will comply, in all material
respects with the 1933 Act and the rules and regulations promulgated thereunder,
has been filed or will be filed in accordance with Section 4 (to the extent
required thereby) and did not at the Time of Sale, and at the Closing Date will
not, contain any untrue statements of a material fact or (when read in
conjunction with the other Time of Sale Information) omit to state a material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided that the
Depositor makes no representation and warranty with respect to (i) any
statements or omissions made in reliance upon and in conformity with the
Underwriter Information or (ii) any Mortgage Loan Seller Information contained
in or omitted from any Issuer Free Writing Prospectus. The parties acknowledge
that none of the Underwriters has furnished any Underwriter Information to the
Depositor expressly for use in any Issuer Free Writing Prospectus.

            (iv)    The Depositor has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the State of
Delaware with corporate power and authority to enter into and perform its
obligations under this Agreement and the Pooling and Servicing Agreement.

            (v)     The execution, delivery and performance of this Agreement
and the Pooling and Servicing Agreement by the Depositor and the consummation of
the transactions contemplated herein and therein by the Depositor and compliance
by the Depositor with its obligations hereunder and thereunder have been duly
authorized by all necessary corporate action and will not (A) contravene any
provision of the certificate of incorporation or by-laws of the Depositor or
applicable law or (B) conflict with or constitute a breach of or default under,
or result in the creation or imposition of any lien, charge or encumbrance upon
any property or assets of the Depositor pursuant to, any contract, indenture,
mortgage, loan agreement, note, lease or other instrument to which the Depositor
is a party or by which it may be bound or to which any of the property or assets
of the Depositor is subject, which conflict, breach, default, lien, charge or
encumbrance is reasonably likely to materially and adversely affect the
Depositor's ability to perform its obligations under this Agreement or the
Pooling and Servicing Agreement.

            (vi)    The Certificates have been duly authorized for issuance and
sale (or will have been so authorized prior to the issuance thereof) pursuant to
this Agreement and the Pooling and Servicing Agreement. When issued,
authenticated and delivered pursuant to the provisions of this Agreement and of
the Pooling and Servicing Agreement against payment of the consideration
therefor in accordance with this Agreement, the Certificates will be duly and


                                        4

validly issued and outstanding and entitled to the benefits provided by the
Pooling and Servicing Agreement, except as the enforceability thereof may be
limited by the effect of (A) bankruptcy, insolvency, reorganization,
receivership, moratorium or other similar laws affecting the enforcement of the
rights of creditors generally, and (B) general principles of equity, whether
enforcement is sought in a proceeding in equity or at law. The Certificates and
the Pooling and Servicing Agreement conform in all material respects to all
statements relating thereto contained in the Prospectus.

            (vii)   No authorization, approval or consent of any court or
governmental authority or agency is necessary in connection with the offering,
issuance or sale of the Certificates hereunder, except such as have been, or as
of the Closing Date will have been, obtained or such as may otherwise be
required under applicable state securities laws in connection with the purchase
and offer and sale of the Certificates by the Underwriters and any recordation
of the respective assignments of the Mortgage Loans to the Trustee pursuant to
the Pooling and Servicing Agreement that have not yet been completed.

            (viii)  This Agreement and each Mortgage Loan Purchase Agreement
have been, and as of the Closing Date the Pooling and Servicing Agreement will
be, duly authorized, executed and delivered by the Depositor. This Agreement and
the Mortgage Loan Purchase Agreements constitute, and as of the Closing Date the
Pooling and Servicing Agreement will constitute, a legal, valid and binding
agreement enforceable against the Depositor in accordance with its terms, except
as such enforceability may be limited by the effect of (A) bankruptcy,
insolvency, reorganization, receivership, moratorium or other similar laws
affecting the enforcement of the rights of creditors generally, (B) general
principles of equity, whether enforcement is sought in a proceeding in equity or
at law, and (C) 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 or are construed to provide
indemnification from securities law liabilities.

            (ix)    At the time of the execution and delivery of the Pooling and
Servicing Agreement, the Depositor (A) will convey to the Trustee, or cause to
be conveyed to the Trustee, all of the Depositor's right, title and interest in
and to the Mortgage Loans, free and clear of any lien, mortgage, pledge, charge,
encumbrance, adverse claim or other security interest (collectively, "Liens")
granted by or imposed upon the Depositor, (B) will not have assigned to any
other person any of its right, title or interest in the Mortgage Loans or in the
Pooling and Servicing Agreement or the Certificates, and (C) will have the power
and authority to transfer or cause to be transferred its right, title and
interest in the Mortgage Loans to the Trustee and to sell the Certificates to
the Underwriters. Upon execution and delivery of the Pooling and Servicing
Agreement by the Trustee, the Trustee will have acquired ownership of all of the
Depositor's right, title and interest in and to the Mortgage Loans except to the
extent disclosed in the Prospectus, and upon delivery to the Underwriters of the
Certificates pursuant hereto, each Underwriter will have good title to the
Certificates purchased by such Underwriter, in each case free of Liens granted
by or imposed upon the Depositor.

            (x)     The Depositor is not, and the issuance and sale of the
Certificates in the manner contemplated by the Prospectus will not cause the
Depositor or the Trust Fund to be,


                                        5

subject to registration or regulation as an "investment company" under the
Investment Company Act of 1940, as amended (the "1940 Act").

            (xi)    Under generally accepted accounting principles ("GAAP") and
for federal income tax purposes, the Depositor will report the transfer of the
Mortgage Loans to the Trustee in exchange for the Certificates and the sale of
the Certificates to the Underwriters pursuant to this Agreement as a sale of the
interest in the Mortgage Loans evidenced by the Certificates. The consideration
received by the Depositor upon the sale of the Certificates to the Underwriters
will constitute at least reasonably equivalent value and fair consideration for
the Certificates. The Depositor will be solvent at all relevant times prior to,
and will not be rendered insolvent by, the sale of the Certificates to the
Underwriters. The Depositor is not selling the Certificates to the Underwriters
with any intent to hinder, delay or defraud any of the creditors of the
Depositor.

            (xii)   The Depositor has not relied on the Underwriters for any
tax, regulatory, accounting or other advice with respect to compliance with or
registration under any statute, rule or regulation of any governmental,
regulatory, administrative or other agency or authority. The Depositor
acknowledges and agrees that (i) the terms of this Agreement and the offering
(including the price of the Certificates) were negotiated at arm's length
between sophisticated parties represented by counsel; (ii) no fiduciary,
advisory or agency relationship between the Depositor and the Underwriters has
been created as a result of any of the transactions contemplated by this
Agreement, irrespective of whether any Underwriter has advised or is advising
the Depositor on other matters; (iii) the Underwriters' obligations to the
Depositor in respect of the offering, and the purchase and sale, of the
Certificates are set forth in this Agreement in their entirety; and (iv) it has
obtained such legal, tax, accounting and other advice as it deems appropriate
with respect to this Agreement and the transactions contemplated hereby and any
other activities undertaken in connection therewith, and it is not relying on
the Underwriters with respect to any such matters.

            (xiii)  The Trust Fund (other than those portions specified in the
Pooling and Servicing Agreement) will qualify as three separate real estate
mortgage investment conduits (each, a "REMIC") for federal income tax purposes
pursuant to Section 860D of the Internal Revenue Code of 1986, as amended (the
"Code"); the REMIC Regular Certificates (as defined in the Pooling and Servicing
Agreement), other than the portion of the Class P Certificates representing the
right to receive any Excess Interest, Exit Fees, Extension Fees or Extension
Term Prepayment Premiums as set forth in the Pooling and Servicing Agreement,
will constitute "regular interests" in a REMIC; the Class R-I Certificates will
constitute the sole class of "residual interests" in REMIC I; the Class R-II
Certificates will constitute the sole class of "residual interests" in REMIC II;
and the Class R-III Certificates will constitute the sole class of "residual
interests" in REMIC III. Portions of the Trust Fund consisting of the right to
receive Excess Interest on ARD Loans, any Exit Fees, Extension Fees or Extension
Term Prepayment Premiums and the Class P Sub-account will qualify as a grantor
trust for federal income tax purposes under the Code, and the Class P
Certificates will represent pro rata undivided beneficial interests in such
grantor trust.

            (xiv)   There are no legal or governmental proceedings pending or,
to the knowledge of the Depositor, threatened to which the Depositor is a party
or to which any of the properties of the Depositor are subject that are required
to be described in the Prospectus or the


                                        6

Time of Sale Information or necessary in order to make the statements therein in
the light of the circumstances under which they were made, not misleading and
that are not so described, nor are there any contracts or other documents to
which the Depositor is a party or to which the Depositor or any of the
properties of the Depositor are subject that are required to be described in the
Prospectus.

            (xv)    At the Closing Date, the respective classes of Certificates
shall have been assigned ratings no lower than those set forth in Schedule I
hereto by the nationally recognized statistical rating organizations identified
in Schedule I hereto (the "Rating Agencies").

            (xvi)   Any taxes, fees and other governmental charges in connection
with the execution, delivery and issuance of this Agreement, the Pooling and
Servicing Agreement, the Mortgage Loan Purchase Agreements and the Certificates
payable by the Depositor (other than income taxes) have been paid or will be
paid at or prior to the Closing Date.

            (xvii)  None of the Depositor or any of its affiliates does business
with the government of Cuba or with any person or affiliate located in Cuba
within the meaning of Section 517.075, Florida Statutes.

            (xviii) The Depositor is not, and on the date on which the first
bona fide offer of the Certificates is made (within the meaning of Rule
164(h)(2) under the 1933 Act) will not be, an "ineligible issuer," as defined in
Rule 405 under the 1933 Act.

            (b)     Each Underwriter, severally and not jointly, represents,
warrants and agrees that:

            (i)     as of the date hereof and as of the Closing Date, such
Underwriter has complied with all of its obligations hereunder; and

            (ii)    in relation to each Member State of the European Economic
            Area which has implemented the Prospectus Directive as defined below
            (each, a "Relevant Member State"), with effect from and including
            the date on which the Prospectus Directive is implemented in that
            Relevant Member State (the "Relevant Implementation Date") it has
            not made and will not make an offer of the Certificates to the
            public in that Relevant Member State other than:

                    (A)   to legal entities which are authorized or regulated to
      operate in the financial markets or, if not so authorized or regulated,
      whose corporate purpose is solely to invest in securities;

                    (B)   to any legal entity which has (1) an average of at
      least 250 employees during the last financial year and (2) a total balance
      sheet of more than (euro)50,000,000, as shown in its last annual or
      consolidated accounts;

                    (C)   to fewer than 100 natural or legal persons (other than
      qualified investors as defined in the Prospectus Directive) subject to
      obtaining the prior consent of the Underwriters; or


                                        7

                    (D)   in any other circumstances falling within Article 3(2)
      of the Prospectus Directive,

provided that no such offer of the Certificates shall require the Depositor or
any Underwriter to publish a prospectus pursuant to Article 3 of the Prospectus
Directive or supplement a prospectus pursuant to Article 16 of the Prospectus
Directive.

      For the purposes of this paragraph (b)(ii), the expression an "offer of
the Certificates to the public" in relation to any Certificates in any Relevant
Member State means the communication in any form and by any means of sufficient
information on the terms of the offer and the Certificates to be offered so as
to enable an investor to decide to purchase or subscribe the Certificates, as
the same may be varied in that Member State by any measure implementing the
Prospectus Directive in that Member State and the expression "Prospectus
Directive" means Directive 2003/71/EC and includes any relevant implementing
measure in each Relevant Member State;

            (iii)   (A)   it has only communicated or caused to be communicated
            and will only communicate or cause to be communicated an invitation
            or inducement to engage in investment activity (within the meaning
            of Section 21 of the Financial Services and Markets Act 2000
            ("FSMA")) received by it in connection with the issue or sale of the
            certificates in circumstances in which Section 21(1) of the FSMA
            does not apply to the Depositor; and

                    (B)   it has complied and will comply with all applicable
            provisions of the FSMA with respect to anything done by it in
            relation to the certificates in, from or otherwise involving the
            United Kingdom.

      2.    Purchase and Sale.

      Subject to the terms and conditions herein set forth and in reliance upon
the representations and warranties herein contained, the Depositor shall sell to
the Underwriters, and each Underwriter shall, severally and not jointly,
purchase from the Depositor, at the related purchase price set forth on Schedule
I hereto, Certificates of each class thereof having an actual or notional amount
as set forth on Schedule I hereto opposite their names. There will be added to
the purchase price of the Certificates an amount equal to interest accrued
thereon pursuant to the terms thereof from December 1, 2007 to but excluding the
Closing Date.

      3.    Delivery and Payment.

      Payment of the aggregate purchase price for, and delivery of, the
Certificates shall be made at 10:00 a.m. New York City time on December 28,
2007, which time and date may be postponed by agreement between the Underwriters
and the Depositor (such time and date of payment and delivery, the "Closing
Date"). Payment shall be made to the Depositor by the Underwriters of the
purchase prices of the Certificates as set forth in Schedule I in immediately
available Federal funds wired to such bank as may be designated by the
Depositor, against delivery of the Certificates. Delivery of the Certificates
will be made in book-entry form through the facilities of The Depository Trust
Company ("DTC"). Each class of Certificates will be represented by one or more
definitive global Certificates to be deposited by or on behalf of the


                                        8

Depositor with DTC or the Trustee. The Certificates will be made available for
examination by the Underwriters not later than 10:00 a.m. New York City time on
the last business day prior to the Closing Date. The closing of the transactions
contemplated hereby shall be made at the offices of Latham & Watkins LLP, 885
Third Avenue, New York, New York 10022, or at such other place as shall be
agreed upon by the Underwriters and the Depositor.

      4.    Offering by Underwriters; Free Writing Prospectuses.

            (a)     It is understood that the Underwriters propose to offer the
Certificates for sale as set forth in the Prospectus. It is further understood
that the Depositor, in reliance upon Policy Statement 105, has not and will not
file an offering statement pursuant to Section 352-e of the General Business Law
of the State of New York with respect to the Certificates. Each Underwriter
severally and not jointly therefore agrees that sales of the Certificates made
by such Underwriter in and from the State of New York will be made only to
institutional investors within the meaning of Policy Statement 105.

            (b)     In connection with the offering of the Certificates, the
Underwriters may each prepare and provide to prospective investors Free Writing
Prospectuses (as defined below), or portions thereof, subject to the following
conditions (to which such conditions each Underwriter agrees (provided that no
Underwriter shall be responsible for any breach of the following conditions by
any other Underwriter)):

                    (i)   Unless preceded or accompanied by the Prospectus, the
      Underwriters shall not convey or deliver any written communication to any
      person in connection with the initial offering of the Certificates, unless
      such written communication (1) is made in reliance on Rule 134 under the
      1933 Act, (2) constitutes a prospectus satisfying the requirements of Rule
      430B under the 1933 Act, or (3) constitutes Time of Sale Information or a
      Free Writing Prospectus that does not constitute Time of Sale Information.
      The Underwriters shall not convey or deliver in connection with the
      initial offering of the Certificates any "computational materials" or "ABS
      term sheets" in reliance on the "Kidder/PSA" no-action letters or any "ABS
      informational and computational material," as defined in Item 1101(a) of
      Regulation AB under the 1933 Act ("ABS Informational and Computational
      Material"), in reliance upon Rules 167 and 426 under the 1933 Act.

                    (ii)  Each Underwriter shall deliver to the Depositor, no
      later than two business days prior to the date of first use thereof or
      such later date as may be agreed to by the Depositor, (a) any Free Writing
      Prospectus that was prepared by or on behalf of such Underwriter (an
      "Underwriter Free Writing Prospectus") and that contains any "issuer
      information," as defined in Rule 433(h) under the 1933 Act and footnote
      271 of the Commission's Securities Offering Reform Release No. 33-8591
      ("Issuer Information") (which the parties hereto agree includes, without
      limitation, Mortgage Loan Seller Information), and (b) any Free Writing
      Prospectus or portion thereof prepared by or on behalf of such Underwriter
      that contains only a description of the final terms of the Certificates.
      Notwithstanding the foregoing, any Free Writing Prospectus that contains
      only ABS Informational and Computational Materials may be delivered by an
      Underwriter to the Depositor not later than the later of (A) two business
      days prior to


                                        9

      the due date for filing of the Prospectus pursuant to Rule 424(b) under
      the 1933 Act or such later date as may be agreed to by the Depositor or
      (B) the date of first use of such Free Writing Prospectus.

                    (iii) Each Underwriter represents and warrants to the
      Depositor that the Free Writing Prospectuses to be furnished to the
      Depositor by such Underwriter pursuant to Section 4(b)(ii) will constitute
      all Free Writing Prospectuses of the type described therein that were
      furnished to prospective investors by such Underwriter in connection with
      its offer and sale of the Certificates.

                    (iv)  Each Underwriter represents and warrants to the
      Depositor that each Free Writing Prospectus required to be provided by it
      to the Depositor pursuant to Section 4(b)(ii) did not, as of the Time of
      Sale, and will not as of the Closing Date, include any untrue statement of
      a material fact or omit any material fact necessary to make the statements
      contained therein (when read in conjunction with the Time of Sale
      Information), in light of the circumstances under which they were made,
      not misleading; provided however, that such Underwriter makes no
      representation to the extent such misstatements or omissions were the
      result of any inaccurate Issuer Information, which information was not
      corrected by Corrective Information subsequently supplied by the Depositor
      or any Mortgage Loan Seller to such Underwriter within a reasonable period
      of time prior to the Time of Sale.

                    (v)   The Depositor agrees to file with the Commission the
      following:

                          (A)   Any Issuer Free Writing Prospectus;

                          (B)   Any Free Writing Prospectus or portion thereof
            delivered by any Underwriter to the Depositor pursuant to Section
            4(b)(ii); and

                          (C)   Any Free Writing Prospectus for which the
            Depositor or any person acting on its behalf provided, authorized or
            approved information that is prepared and published or disseminated
            by a person unaffiliated with the Depositor or any other offering
            participant that is in the business of publishing, radio or
            television broadcasting or otherwise disseminating communications.

            Notwithstanding the foregoing, the Depositor shall not be required
            to file (1) Issuer Information contained in any Underwriter Free
            Writing Prospectus or Free Writing Prospectus of any other offering
            participant other than the Depositor, if such information is
            included or incorporated by reference in a prospectus or Free
            Writing Prospectus previously filed with the Commission that relates
            to the offering of the Certificates, or (2) any Free Writing
            Prospectus or portion thereof that contains a description of the
            Certificates or the offering of the Certificates which does not
            reflect the final terms thereof.

            The Depositor is required to file such Free Writing Prospectuses
            with the Commission in electronic format and the Underwriters shall
            use reasonable efforts to provide to the Depositor such Free Writing
            Prospectuses, or portions thereof, in


                                       10

            either Microsoft Word(R) or Microsoft Excel(R) format and not in a
            PDF, except to the extent that the Depositor, in its sole
            discretion, waives such requirements,

                    (vi)  Any Free Writing Prospectus required to be filed
      pursuant to Section 4(b)(v) by the Depositor shall be filed with the
      Commission not later than the date of first use of the Free Writing
      Prospectus, except that:

                          (A)   Any Free Writing Prospectus or portion thereof
            required to be filed that contains only the description of the final
            terms of the Certificates shall be filed by the Depositor with the
            Commission within two days of the later of the date such final terms
            have been established for all classes of Certificates and the date
            of first use;

                          (B)   Any Free Writing Prospectus or portion thereof
            required to be filed that contains only ABS Informational and
            Computational Material shall be filed by the Depositor with the
            Commission not later than the later of the due date for filing the
            final Prospectus relating to the Certificates pursuant to Rule
            424(b) under the 1933 Act or two business days after the first use
            of such Free Writing Prospectus; and

                          (C)   Any Free Writing Prospectus required to be
            filed pursuant to Section 4(b)(v)(C) shall, if no payment has been
            made or consideration has been given by or on behalf of the
            Depositor for the Free Writing Prospectus or its dissemination, be
            filed by the Depositor with the Commission not later than four
            business days after the Depositor becomes aware of the publication,
            radio or television broadcast or other dissemination of the Free
            Writing Prospectus.

                    (vii) Each Underwriter shall file with the Commission any
      Free Writing Prospectus that is used or referred to by it and distributed
      by or on behalf of such Underwriter in a manner reasonably designed to
      lead to its broad, unrestricted dissemination not later than the date of
      the first use of such Free Writing Prospectus.

                    (viii) Notwithstanding the provisions of Section 4(b)(vii),
      each Underwriter shall file with the Commission any Free Writing
      Prospectus for which such Underwriter or any person acting on its behalf
      provided, authorized or approved information that is prepared and
      published or disseminated by a person unaffiliated with the Depositor or
      any other offering participant that is in the business of publishing,
      radio or television broadcasting or otherwise disseminating written
      communications and for which no payment was made or consideration given by
      or on behalf of the Depositor or any other offering participant, not later
      than four business days after such Underwriter becomes aware of the
      publication, radio or television broadcast or other dissemination of the
      Free Writing Prospectus.

                    (ix)  Notwithstanding the provisions of Sections 4(b)(v) and
      4(b)(vii), neither the Depositor nor any Underwriter shall be required to
      file any Free Writing Prospectus that does not contain substantive changes
      from or additions to a Free Writing Prospectus previously filed with the
      Commission, and no Underwriter shall be required to


                                       11

      file any Free Writing Prospectus to the extent that the information
      contained therein is included in a prospectus or Free Writing Prospectus
      previously filed that relates to the offering of the Certificates.

                    (x)   The Depositor and the Underwriters each agree that any
      Free Writing Prospectuses prepared by it shall contain the following
      legend, or substantially equivalent legend that complies with Rule 433 of
      the 1933 Act:

                  The depositor has filed a registration statement (including a
                  prospectus) with the SEC for the offering to which this
                  communication relates. Before you invest, you should read the
                  prospectus in that registration statement and other documents
                  the depositor has filed with the SEC for more complete
                  information about the depositor, the issuing trust, and this
                  offering. You may get these documents for free by visiting
                  EDGAR on the SEC Web site at www.sec.gov. Alternatively, the
                  depositor, any underwriter or any dealer participating in the
                  offering will arrange to send you the prospectus if you
                  request it by calling toll-free 1-866-718-1649.

                    (xi)  The Depositor and each Underwriter agree to retain all
      Free Writing Prospectuses that they have used and that are not required to
      be filed pursuant to this Section 4 for a period of three years following
      the initial bona fide offering of the Certificates.

                    (xii) (A)   If the Depositor becomes aware that, as of the
      Time of Sale, any Issuer Free Writing Prospectus delivered to an investor
      in any Certificate contained any untrue statement of a material fact or
      omitted to state a material fact necessary in order to make the statements
      contained therein (when read in conjunction with the Time of Sale
      Information), in light of the circumstances under which they were made,
      not misleading (a "Defective Issuer Free Writing Prospectus"), the
      Depositor shall notify the Underwriters of such untrue statement or
      omission within one business day after discovery and the Depositor shall,
      if requested by the Underwriters, prepare and deliver to the Underwriters
      a Free Writing Prospectus that corrects the material misstatement or
      omission in the Defective Issuer Free Writing Prospectus (such corrected
      Issuer Free Writing Prospectus, a "Corrected Issuer Free Writing
      Prospectus").

                          (B)   If any Underwriter becomes aware that, as of
            the Time of Sale, any Underwriter Free Writing Prospectus delivered
            to an investor in any Certificates contained any untrue statement of
            a material fact or omitted to state a material fact necessary in
            order to make the statements contained therein (when read in
            conjunction with the Time of Sale Information), in light of the
            circumstances under which they were made, not misleading (together
            with a Defective Issuer Free Writing Prospectus, a "Defective Free
            Writing Prospectus"), such Underwriter shall notify the Depositor of
            such untrue statement or omission within one business day after
            discovery.


                                       12

                          (C)   The Underwriters shall, if requested by the
            Depositor:

                                (1)   if the Defective Free Writing Prospectus
                  was an Underwriter Free Writing Prospectus, prepare a Free
                  Writing Prospectus that corrects the material misstatement in
                  or omission from the Defective Free Writing Prospectus
                  (together with a Corrected Issuer Free Writing Prospectus, a
                  "Corrected Free Writing Prospectus");

                                (2)   deliver the Corrected Free Writing
                  Prospectus to each investor which received the Defective Free
                  Writing Prospectus prior to entering into a contract of sale
                  with such investor;

                                (3)   notify such investor in a prominent
                  fashion that the prior contract of sale with the investor has
                  been terminated, and of the investor's rights as a result of
                  termination of such agreement;

                                (4)   provide such investor with an opportunity
                  to affirmatively agree to purchase the Certificates on the
                  terms described in the Corrected Free Writing Prospectus; and

                                (5)   comply with any other requirements for
                  reformation of the original contract of sale with such
                  investor, as described in Section IV.A.2.c of Commission's
                  Securities Offering Reform Release No. 33-8591.

                          (D)   If the Defective Free Writing Prospectus was an
            Issuer Free Writing Prospectus, and the Underwriters shall in good
            faith incur any costs to an investor in connection with the
            reformation of the contract of sale with the investor, the Depositor
            agrees to reimburse the Underwriters for such costs; provided that,
            before incurring such costs, the Underwriters first permit the
            Depositor access to the applicable investor and an opportunity to
            attempt to mitigate such costs through direct negotiation with such
            investor.

                    (xiii) Each Underwriter covenants with the Depositor that
      after the Prospectus is available such Underwriter shall not distribute
      any written information concerning the Certificates to a prospective
      investor unless such information is preceded or accompanied by the
      Prospectus.

      5.    Covenants of the Depositor.

      The Depositor covenants with each Underwriter as follows:

            (a)     The Depositor will give each of the Underwriters notice of
its intention to prepare, use, authorize, approve, refer to or file any Issuer
Free Writing Prospectus or to file or prepare (i) any amendment to the
Registration Statement at any time prior to the Closing Date or (ii) any
amendment or supplement to the Prospectus (including any revised prospectus that
the Depositor proposes for use by the Underwriters in connection with the
offering of the Certificates and that differs from the prospectus on file at the
Commission at the time the


                                       13

Registration Statement became effective, whether or not such revised prospectus
is required to be filed pursuant to Rule 424(b) of the 1933 Act Regulations) at
any time during the period when a prospectus relating to the Certificates is
required to be delivered under the 1933 Act, and the Depositor will furnish the
Underwriters with copies of any such Issuer Free Writing Prospectus, amendment
or supplement a reasonable amount of time prior to such proposed filing or use,
as the case may be, and will not prepare, use, authorize, approve, refer to or
file any such Issuer Free Writing Prospectus or file any such amendment or
supplement or use any such prospectus to which the Underwriters shall reasonably
object.

            (b)     The Depositor will promptly give each Underwriter notice of
(i) any request by the Commission for any amendment of the Registration
Statement or the Prospectus or for any additional information relating to the
Certificates, (ii) any written notification received by the Depositor of
suspension of qualification of the Certificates for sale in any jurisdiction or
the initiation or threatening of any proceeding for such purpose and (iii) the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the institution or, to the knowledge of the Depositor,
threatening any proceeding for that purpose. The Depositor will use its best
efforts to prevent the issuance of any such stop order and, if issued, to obtain
as soon as possible the withdrawal thereof.

            (c)     The Depositor will cause the Prospectus to be transmitted to
the Commission for filing pursuant to Rule 424(b) under the 1933 Act by means
reasonably calculated to result in filing with the Commission pursuant to said
rule. Subject to Section 4, the Depositor will cause the Issuer Free Writing
Prospectus to be transmitted for filing pursuant to Rule 433 under the 1933 Act
by means reasonably calculated to result in filing with the Commission pursuant
to said rule.

            (d)     The Depositor will furnish to each Underwriter, from time to
time during the period when a prospectus relating to the Certificates is
required to be delivered under the 1933 Act, such number of copies of the
Prospectus and each Free Writing Prospectus (as amended or supplemented) as such
Underwriter may reasonably request for the purposes contemplated by the 1933 Act
or the Securities Exchange Act of 1934, as amended (the "1934 Act") or the
respective applicable rules and regulations of the Commission thereunder.

            (e)     If, during the period after the first date of the public
offering of the Certificates in which a prospectus relating to the Certificates
is required to be delivered under the 1933 Act, any event shall occur as a
result of which it is necessary to amend or supplement the Prospectus in order
to make the Prospectus not misleading in the light of the circumstances existing
at the time it is delivered to a purchaser of Certificates, if the Depositor has
actual knowledge of the event, and if the event is not otherwise disclosed in a
filing to the Registration Statement pursuant to Section 13 or 15(d) of the 1934
Act, the Depositor will forthwith amend or supplement the Prospectus so that, as
so amended or supplemented, the Prospectus will not include an untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements therein, in the light of the circumstances existing at the time
it is delivered to a purchaser, not misleading, and the Depositor will furnish
to each Underwriter a reasonable number of copies of such amendment or
supplement.


                                       14

            (f)     The Depositor will endeavor to arrange for the qualification
of the Certificates for sale under the applicable securities laws of such states
and other jurisdictions of the United States as the Underwriters may reasonably
designate and will maintain such qualification in effect so long as required for
the initial distribution of Certificates; provided, however, that the Depositor
shall not be obligated to qualify as a foreign corporation in any jurisdiction
in which it is not so qualified or to file a general consent to service of
process in any jurisdiction.

            (g)     The Depositor will use the net proceeds received by it from
the sale of the Certificates in the manner specified in the Prospectus under
"Use of Proceeds".

            (h)     Whether or not the transactions contemplated by this
Agreement are consummated, the Depositor will pay or cause to be paid all
expenses incident to the performance of the obligations of the Depositor under
this Agreement, including, without limitation, (i) the fees, disbursements and
expenses of the Depositor's counsel and accountants in connection with the
purchase of the Mortgage Loans and the issuance and sale of the Certificates,
(ii) all fees and expenses incurred in connection with the registration and
delivery of the Certificates under the 1933 Act, and all other fees or expenses
in connection with the preparation and filing of the Registration Statement, the
Time of Sale Information, any Issuer Free Writing Prospectus, the Prospectus and
amendments and supplements to any of the foregoing, including all printing costs
associated therewith, and the mailing and delivering of copies thereof to the
Underwriters and dealers, in the quantities specified above, (iii) all costs and
expenses related to the transfer and delivery of the Certificates to the
Underwriters, including any transfer or other taxes payable thereon, (iv) the
costs of printing or producing any "blue sky" memorandum in connection with the
offer and sale of the Certificates under state securities laws and all expenses
in connection with the qualification of the Certificates for the offer and sale
under state securities laws as provided in Section 5(f), including filing fees
and the reasonable fees and disbursements of counsel for the Underwriters in
connection with such qualification and in connection with the "blue sky"
memorandum, (v) the cost of printing the Certificates, (vi) the upfront costs
and charges of any transfer agent, registrar or depository, (vii) the fees and
expenses of the rating agencies incurred in connection with the issuance and
sale of the Certificates and (viii) all other costs and expenses incident to the
performance of the obligations of the Depositor hereunder for which provision is
not otherwise made in this Section. Except as herein provided, the Underwriters
shall be responsible for the payment of all costs and expenses incurred by them,
including, without limitation, (i) the fees and disbursements of counsel of the
Underwriters and (ii) such additional costs arising out of any Free Writing
Prospectuses prepared by or on behalf of the Underwriters and the filing of such
materials, if required, with the Commission.

            (i)     The Depositor shall obtain a letter from Deloitte & Touche
LLP, certified public accountants, satisfactory in form and substance to the
Depositor and the Underwriters, to the effect that such accountants have
performed certain specified procedures, all of which have been agreed to by the
Depositor and the Underwriters, as a result of which they have determined that
the information included in the Time of Sale Information that the accountants
have examined in accordance with such agreed upon procedures, is accurate except
as to such matters that are not deemed by the Depositor or the Underwriters to
be material.


                                       15

      6.    Conditions of Underwriters' Obligations.

      Each Underwriter's obligation to purchase the Certificates allocated to it
as set forth on Schedule I hereto shall be subject to the accuracy of the
representations and warranties on the part of the Depositor contained herein as
of the date hereof and as of the Closing Date, to the performance by the
Depositor of its obligations hereunder and to the following conditions:

            (a)     No stop order suspending the effectiveness of the
Registration Statement shall be in effect, and no proceedings for that purpose
shall be pending or, to the Depositor's knowledge, threatened by the Commission
and the Prospectus Supplement and each Free Writing Prospectus required to be
filed by the Depositor pursuant to Section 4(b) shall have been filed or
transmitted for filing by means reasonably calculated to result in a filing with
the Commission pursuant to Rule 424(b) under the 1933 Act or Rule 433 under the
1933 Act, as applicable.

            (b)     On the Closing Date, such Underwriter shall have received:

                    (i)   One or more opinions, dated the Closing Date, of
      counsel to the Depositor, in form and substance satisfactory to such
      Underwriter, substantially to the effect that:

                          (A)   The Depositor is a corporation in good standing
            under the laws of the State of Delaware.

                          (B)   The Depositor has corporate power and authority
            to enter into and perform its obligations under this Agreement and
            the Pooling and Servicing Agreement.

                          (C)   Each of this Agreement and the Pooling and
            Servicing Agreement has been duly authorized, executed and delivered
            by the Depositor. Upon due authorization, execution and delivery by
            the other parties thereto, the Pooling and Servicing Agreement will
            constitute a valid, legal and binding agreement of the Depositor,
            enforceable against the Depositor in accordance with its terms,
            except as enforceability may be limited by (1) bankruptcy,
            insolvency, liquidation, receivership, moratorium, reorganization or
            other similar laws affecting the enforcement of the rights of
            creditors generally, (2) general principles of equity, whether
            enforcement is sought in a proceeding in equity or at law and (3)
            such other exceptions as are reasonably acceptable to the
            Underwriters.

            executed, authenticated and delivered in accordance with the Pooling
            and Servicing Agreement and paid for in accordance with this
            Agreement, will be entitled to the benefits of the Pooling and
            Servicing Agreement.

                          (E)   The Registration Statement was declared
            effective under the 1933 Act and, to the best of such counsel's
            knowledge and information, no stop order suspending the
            effectiveness of the Registration Statement has been


                                       16

            issued under the 1933 Act and not withdrawn, and no proceedings for
            that purpose have been initiated or threatened by the Commission.

                          (F)   At the time it became effective, the
            Registration Statement (other than any financial or statistical
            information included or incorporated by reference therein, as to
            which no opinion need be rendered) complied as to form in all
            material respects with the requirements of the 1933 Act and the 1933
            Act Regulations.

                          (G)   To such counsel's knowledge and information,
            there are no material contracts, indentures, or other documents of
            the Depositor required to be described or referred to in the
            Registration Statement or to be filed as exhibits thereto other than
            those described or referred to therein or filed or incorporated by
            reference as exhibits thereto.

                          (H)   The Pooling and Servicing Agreement is not
            required to be qualified under the Trust Indenture Act of 1939, as
            amended, and the issuance and sale of the Certificates in the manner
            contemplated by the Prospectus will not cause the Trust Fund to be
            subject to registration or regulation as an "investment company"
            under the Investment Company Act of 1940, as amended.

                          (I)   No consent, approval, authorization, or order
            of any State of New York or federal court or governmental agency or
            body is required for the consummation by the Depositor of the
            transactions contemplated herein, except (1) such as have been
            obtained, (2) such as may be required under the blue sky laws of any
            jurisdiction in connection with the purchase and sale of the
            Certificates by the Underwriters, as to which no opinion need be
            expressed and (3) any recordation of the assignments of the Mortgage
            Loans to the Trustee pursuant to the Pooling and Servicing Agreement
            that has not yet been completed.

                          (J)   Neither the sale of the Certificates to the
            Underwriters pursuant to this Agreement, nor the consummation by the
            Depositor of any other of the transactions contemplated by, or the
            fulfillment by the Depositor of the terms of, this Agreement or the
            Pooling and Servicing Agreement, will conflict with or result in a
            breach or violation of any term or provision of, or constitute a
            default (or an event which with the passing of time or notification
            or both, would constitute a default) under, (1) the certificate of
            incorporation or by-laws of the Depositor or, (2) to the knowledge
            of such counsel, any material indenture, agreement or instrument to
            which the Depositor is a party or by which it is bound or, (3) any
            State of New York or federal statute or regulation applicable to the
            Depositor or, (4) to the knowledge of such counsel, any order of any
            New York or federal court, regulatory body, administrative agency or
            governmental body having jurisdiction over the Depositor except, in
            the case of either (2) or (4), for any conflict, breach, violation
            or default that, in the judgment of such counsel, is not reasonably
            likely to materially and adversely affect the Depositor's ability to
            perform its obligations under this Agreement or the Pooling and
            Servicing Agreement.


                                       17

                    (ii)  An opinion, dated the Closing Date, of counsel to the
      Underwriters, reasonably acceptable to the Underwriters.

                    (iii) In giving their opinions required by the foregoing
      subsections (i) and (ii) of this Section, counsel to the Depositor and the
      Underwriters, respectively, shall in each case additionally state that
      nothing has come to such counsel's attention that has caused it to believe
      that (i) in the case of counsel to the Depositor, the Registration
      Statement, the Prospectus or the Time of Sale Information, and (ii) in the
      case of counsel to the Underwriters, the Prospectus or the Time of Sale
      Information (in each case other than any financial statements and
      supporting schedules and statistical and/or accounting information
      included therein, as to which no statement need be made), in the case of
      the Registration Statement, as of the time it became effective, in the
      case of the Prospectus, as of the date thereof or as of the Closing Date,
      and in the case of the Time of Sale Information, as of the Time of Sale,
      contained an untrue statement of a material fact or omitted to state a
      material fact necessary to make the statements therein, in the light of
      the circumstances under which they were made, not misleading. Such
      statement shall be based upon conferences and telephone conversations with
      representatives of the parties hereto, the Mortgage Loan Sellers, the
      Master Servicer, the Special Servicer, the Paying Agent and the Trustee
      and such statement may be qualified that, with limited exception, such
      counsel will not have reviewed any loan documents.

      Such opinion(s) may express its (their) reliance as to factual matters on
the representations and warranties made by, and on certificates or other
documents furnished by officers and/or authorized representatives of, the
parties to this Agreement and the Pooling and Servicing Agreement and on
certificates furnished by public officials. Such opinion(s) may assume the due
authorization, execution and delivery of the instruments and documents referred
to therein by the parties thereto other than the party on behalf of which such
opinion is being rendered. Such opinion(s) may be qualified as an opinion only
on the General Corporation Law of the State of Delaware, the laws of the State
of New York and the federal law of the United States.

            (c)     On the Closing Date, each Underwriter shall have received a
favorable opinion, dated the Closing Date, of special tax and ERISA counsel to
the Depositor (i) regarding the qualification of each of REMIC I, REMIC II and
REMIC III as a real estate mortgage investment conduit within the meaning of
Sections 860A through 860G of the Code and the qualification of the Class P
Grantor Trust (as defined in the Pooling and Servicing Agreement) as a grantor
trust under the Code, and (ii) to the effect that the statements in the Base
Prospectus and the Prospectus Supplement under the headings "Material Federal
Income Tax Consequences" and "Certain ERISA Considerations", to the extent that
they constitute matters of federal law or legal conclusions with respect
thereto, while not purporting to discuss all possible consequences of investment
in the Certificates, are correct in all material respects with respect to those
consequences or matters that are discussed therein. Such opinion(s) may express
its (their) reliance as to factual matters on the representations and warranties
made by, and on certificates or other documents furnished by officers and/or
authorized representatives of, the parties to this Agreement and the Pooling and
Servicing Agreement and on certificates furnished by public officials. Such
opinion(s) may assume the due authorization, execution and delivery of the


                                       18

instruments and documents referred to therein by the parties thereto. Such
opinion(s) may be qualified as an opinion only on the federal tax and ERISA law
of the United States.

            (d)     The Depositor shall have delivered to each Underwriter a
certificate, dated the Closing Date, and signed by the President, a Senior Vice
President or a Vice President of the Depositor, to the effect that the signer of
such certificate has examined, or has relied upon an examination conducted by
appropriate persons authorized by him or her of, the Agreement, the Prospectus,
the Pooling and Servicing Agreement and various other closing documents, and
that, to the best of his or her knowledge after reasonable investigation:

                    (i)   the representations and warranties of the Depositor in
      this Agreement and the Pooling and Servicing Agreement are true and
      correct in all material respects;

                    (ii)  the Depositor has, in all material respects, complied
      with all the agreements and satisfied all the conditions on its part to be
      performed or satisfied hereunder at or prior to the Closing Date;

                    (iii) since the date of this Agreement, there has been no
      material adverse change in the financial condition of the Depositor; and

                    (iv)  no stop order suspending the effectiveness of the
      Registration Statement has been issued and no proceedings for that purpose
      have been initiated or threatened by the Commission.

            (e)     Each Mortgage Loan Seller shall have delivered to each
Underwriter a certificate, dated the Closing Date, and signed by the President,
a Senior Vice President or a Vice President of the Mortgage Loan Seller to the
effect that:

                    (i)   the representations and warranties of the Mortgage
      Loan Seller in the respective Mortgage Loan Purchase Agreement are true
      and correct in all material respects except as indicated on Schedule A
      thereto;

                    (ii)  the Mortgage Loan Seller has, in all material
      respects, complied with all the agreements and satisfied all the
      conditions on its part to be performed or satisfied under the respective
      Mortgage Loan Purchase Agreement at or prior to the Closing Date; and

                    (iii) since the date of this Agreement, there has been no
      material adverse change in the financial condition of the Mortgage Loan
      Seller.

            (f)     The Depositor and each Underwriter shall have received from
Deloitte & Touche LLP, certified public accountants, a letter dated the Closing
Date, in form and substance satisfactory to such Underwriter, stating in effect
that:

                    (i)   they have performed certain specified procedures as a
      result of which they have determined that certain information of an
      accounting, financial or statistical nature set forth in the Prospectus
      Supplement agrees with the data sheet or


                                       19

      computer tape prepared by or on behalf of each Mortgage Loan Seller,
      unless otherwise noted in such letter; and

                    (ii)  they have compared the data contained in the data
      sheet or computer tape referred to in the immediately preceding clause (i)
      to information contained in the Mortgage Files and in such other sources
      as shall be specified by them, and found such data and information to be
      in agreement, unless otherwise noted in such letter.

            (g)     The Depositor shall have received the accountant's letters
specified in Section 5(i).

            (h)     Each Underwriter shall have received, with respect to each
of the Master Servicer, the Special Servicer, the Paying Agent and the Trustee,
a favorable opinion of counsel, dated the Closing Date, addressing the valid
existence of such party under the laws of the jurisdiction of its organization,
the due authorization, execution and delivery of the Pooling and Servicing
Agreement by such party and, subject to the same limitations as set forth in
Section 6(b)(i)(C), the enforceability of the Pooling and Servicing Agreement
against such party and such other opinions as shall be reasonably requested by
such Underwriter including an opinion that certain disclosure relating to such
parties complies as to form with the applicable requirements of Regulation AB.
Such opinion may express its reliance as to factual matters on representations
and warranties made by, and on certificates or other documents furnished by,
officers and/or authorized representatives of parties to, the Pooling and
Servicing Agreement and on certificates furnished by public officials. Such
opinion may assume the due authorization, execution and delivery of the
instruments and documents referred to therein by the parties thereto other than
the party on behalf of which such opinion is being rendered.

            (i)     Subsequent to the date hereof, there shall not have occurred
any change, or any development involving a prospective change, in or affecting
the business or properties of the Depositor or a Mortgage Loan Seller (including
any of the Mortgage Loans) which such Underwriter concludes, in the reasonable
judgment of such Underwriter, materially impairs the investment quality of the
Certificates so as to make it impractical or inadvisable to proceed with the
public offering or the delivery of the Certificates as contemplated by the Time
of Sale Information (excluding the Corrective Information) and the Prospectus.

            (j)     The Certificates shall have been assigned ratings by the
Rating Agencies (as defined in the Pooling and Servicing Agreement) no less than
those set forth on Schedule I and such ratings shall not have been withdrawn,
suspended or qualified.

            (k)     The Underwriters shall have received copies of any opinions
of counsel to the Depositor supplied to the Rating Agencies relating to certain
matters with respect to the Certificates. Any such opinions shall be dated the
Closing Date and addressed to the Underwriters or accompanied by reliance
letters addressed to the Underwriters.

            (l)     The Depositor shall have furnished to the Underwriters such
further opinions, information, certificates and documents as the Underwriters
may reasonably have requested, and all proceedings in connection with the
transactions contemplated by this


                                       20

Agreement and all documents incident hereto shall be in all material respects
reasonably satisfactory in form and substance to the Underwriters and their
counsel.

      7.    Indemnification.

            (a)     The Depositor shall indemnify and hold harmless each
Underwriter (severally and not jointly), its directors and officers and each
person, if any, who controls such Underwriter within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any
and all expenses, losses, claims, damages and other liabilities (including
without limitation the reasonable costs of investigation and legal defense) (the
"Liabilities") caused by (i) any untrue statement or alleged untrue statement of
any material fact contained in the Registration Statement or any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, not misleading, or any untrue
statement or alleged untrue statement of any material fact contained in the
Prospectus or any omission or alleged omission to state therein a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading or (ii) any untrue statement or
alleged untrue statement of a material fact contained in any Issuer Free Writing
Prospectus or any Issuer Information contained in any Underwriter Free Writing
Prospectus, or the omission or alleged omission to state a material fact
necessary to make the statements therein (when read in conjunction with the
other Time of Sale Information), in light of the circumstances under which they
were made, not misleading, which was not corrected by Corrective Information
subsequently supplied by the Depositor or any Mortgage Loan Seller to any
Underwriter within a reasonable period of time prior to the Time of Sale, or
(iii) any breach of the representation and warranty in Section 1(a)(xviii);
provided that, in the case of clauses (i) and (ii) above, insofar as the
Liabilities are caused by any such untrue statement or omission or alleged
untrue statement or omission with respect to any information in the Prospectus
as to which any Underwriter has agreed to indemnify the Depositor pursuant to
Section 7(b), the Depositor shall have no obligation to so indemnify and hold
harmless; and provided, further, that the Depositor shall have no obligation to
so indemnify and hold harmless to the extent that the Liabilities arise out of
or are based upon an untrue statement or omission or an alleged untrue statement
or omission with respect to the Mortgage Loan Seller Information (including
without limitation untrue statements or alleged untrue statements or omissions
or alleged untrue omissions in the portions of the Prospectus Supplement and any
free writing prospectus under the heading "Yield, Prepayment and Maturity
Considerations" that arise out of or are based upon untrue statements or alleged
untrue statements or omissions or alleged omissions in the Mortgage Loan Seller
Information).

            (b)     Each Underwriter shall, severally and not jointly, indemnify
and hold harmless the Depositor, its directors and its officers who signed the
Registration Statement and each person, if any, who controls the Depositor
within the meaning of either Section 15 of the 1933 Act or Section 20 of the
1934 Act against any and all Liabilities as incurred, but only with respect to
Liabilities caused by any (i) untrue statements or alleged untrue statements of
a material fact, or omissions or alleged omissions to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, in the Underwriter Information and
(ii) untrue statements or alleged untrue statements of a material fact, in any
Underwriter Free Writing Prospectus prepared by or on behalf of such Underwriter
or omission or alleged omission to state in such Underwriter Free


                                       21

Writing Prospectus a material fact necessary in order to make the statements
therein (when read in conjunction with the Time of Sale Information), in the
light of the circumstances under which they were made, not misleading; provided,
that no Underwriter shall be obligated to so indemnify and hold harmless (A) to
the extent such Liabilities are caused by a misstatement or omission resulting
from an error or omission in the Issuer Information which was not corrected by
Corrective Information subsequently supplied by the Depositor or any Mortgage
Loan Seller to any Underwriter within a reasonable period of time prior to the
Time of Sale or (B) with respect to information that is also contained in the
Time of Sale Information.

            (c)     Each indemnified party shall give notice in writing as
promptly as reasonably practicable to each indemnifying party of any action
commenced against it in respect of which indemnity may be sought hereunder, but
failure to so notify an indemnifying party shall not relieve such indemnifying
party from any liability which it may have otherwise than under subsection (a)
or (b) of this Section 7. Upon request of the indemnified party, the
indemnifying party shall retain counsel reasonably satisfactory to the
indemnified party to represent the indemnified party and any others the
indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding as incurred. If any
action is brought against any indemnified party and it notifies the indemnifying
party of the commencement thereof, the indemnifying party may participate at its
own expense in the defense of any such action. The indemnifying party may elect
to assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party by written notice delivered to the indemnified party promptly
after receiving the aforesaid notice from the indemnified party. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have agreed to the retention of such counsel, (ii) the named parties
to any such proceeding (including any impleaded parties) include both the
indemnifying party and the indemnified party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them or (iii) the indemnifying party shall have failed to
designate within a reasonable period of time counsel reasonably satisfactory to
the indemnified party (in which case the fees and expenses shall be paid as
incurred by the indemnifying party). In no event shall the indemnifying parties
be liable for fees and expenses of more than one counsel (in addition to any
local counsel) separate from their own counsel for all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
An indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, which consent shall not be unreasonably
withheld. However, 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 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 30 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


                                       22

or, if such settlement provides for an unconditional release of the indemnified
party, without any admission of fault, culpability or failure to act or on
behalf 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, without the consent of the
indemnified party.

            (d)     If the indemnification provided for in this Section 7 is due
in accordance with its terms but is for any reason unavailable to an indemnified
party under subsection (a) or (b), or insufficient to hold harmless an
indemnified party, in respect of any losses, claims, damages or liabilities
under subsection (a) or (b) on grounds of public policy or otherwise, 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 (i) in such proportion as is
appropriate to reflect the relative benefits received by the Depositor on the
one hand and the applicable Underwriter on the other from the offer and sale of
the Certificates pursuant hereto or (ii) if the allocation provided by clause
(i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Depositor on the one hand and of such
Underwriter on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or other liabilities, as well as any
other relevant equitable considerations. The relative benefits received by the
Depositor on the one hand, and such Underwriter on the other, in connection with
the offering of the Certificates underwritten by such Underwriter shall be
deemed to be in the same respective proportions that the total proceeds from the
sale of the Certificates underwritten by such Underwriter (before deducting
expenses) received by the Depositor and the amount by which (i) the total price
received by such Underwriter with respect to the initial resale to investors in
the Certificates acquired by such Underwriter exceeds (ii) the total
underwriting discounts and commissions received by such Underwriter (or, if no
such Underwriter discounts and commissions are payable hereunder, the amount of
the other fees payable to such Underwriter in connection with the offering of
the Certificates), bear to the aggregate offering price of the Certificates. The
relative fault of the Depositor on the one hand and of such Underwriter on the
other 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 the
Depositor or by such Underwriter, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

            (e)     The parties hereto agree that it would not be just and
equitable if contribution were determined by pro rata allocation or by any other
method of allocation that does not take account of the considerations referred
to in subsection (d) above. The amount paid or payable by an indemnified party
as a result of the losses, claims, damages or other liabilities referred to in
this Section 7 shall be deemed to include any legal fees and disbursements or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such claim. If any expenses so paid by the
indemnifying party are subsequently determined to not be required to be borne by
the indemnifying party hereunder, the party which received such payment shall
promptly refund the amount so paid to the party which made such payment.
Notwithstanding the provisions of subsection (d) above or this subsection (e),
no Underwriter shall be required to contribute any amount in excess of the
amount by which (i) the total underwriting discounts and commissions and other
fees received by such Underwriter in


                                       23

connection with the offering of the Certificates exceeds (ii) the amount of
damages that such Underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation. The remedies provided for in
this Section 7 are not exclusive and shall not limit any rights or remedies that
may otherwise be available to any indemnified party at law or in equity.

            (f)     The indemnity and contribution agreements contained in this
Section 7 shall remain operative and in full force and effect regardless of (i)
any termination of this Agreement, (ii) any investigation made by the Depositor,
an Underwriter, any of their respective directors or officers, or any person
controlling the Depositor or such Underwriter within the meaning of either
Section 15 of the 1933 Act or Section 20 of the 1934 Act, and (iii) acceptance
of and payment for any of the Certificates.

            (g)     The Underwriters' respective obligations to contribute
pursuant to this Section 7 are several in proportion to the respective amount of
Certificates they have purchased hereunder, and not joint.

            (h)     Each Underwriter (the "Indemnifying Underwriter") will
indemnify and hold harmless the other Underwriters and each person, if any, who
controls such Underwriter within the meaning of either the 1933 Act or the 1934
Act (the "Non-Indemnifying Underwriter") from and against any and all losses,
claims, damages or liabilities, joint or several, to which the Non-Indemnifying
Underwriter becomes subject under the 1933 Act, the 1934 Act or other federal or
state statutory law or regulation, common law or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon (i) any untrue statement or alleged untrue statement of a
material fact or the omission or alleged omission (when read in conjunction with
the Time of Sale Information) to state a material fact necessary in order to
make the statements, in the light of the circumstances under which they were
made, not misleading at the Time of Sale, contained in any Underwriter Free
Writing Prospectus prepared by, or on behalf of, or used or referred to by, such
Indemnifying Underwriter or (ii) the failure of such Indemnifying Underwriter,
or any member of its selling group, to comply with any provision of Sections
4(b) or 9, and agrees to reimburse such Non-Indemnifying Underwriter, 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, except to the extent such losses, claims, damages or
liabilities are caused by a misstatement or omission resulting from an error or
omission in the Issuer Information which was not corrected by Corrective
Information subsequently supplied by the Depositor or any Mortgage Loan Seller
to any Underwriter within a reasonable period of time prior to the Time of Sale.
This agreement will be in addition to any liability that any Underwriter may
otherwise have.

      8.    Representations and Warranties to Survive Delivery.

      All representations and warranties of the Depositor contained in this
Agreement shall remain operative and in full force and effect, regardless of any
investigation made by or on


                                       24

behalf of any Underwriter or any controlling person in respect of such
Underwriter, and shall survive delivery of the Certificates to the Underwriters.

      9.    Defaulting Underwriter.

      If, on the Closing Date, any of the Underwriters shall fail or refuse to
purchase Certificates that it has agreed to purchase hereunder on such date, and
the aggregate principal amount of Certificates which such defaulting Underwriter
agreed but failed or refused to purchase is not more than one-tenth of the
aggregate principal amount of Certificates to be purchased on such date, the
other Underwriter shall be obligated to purchase the Certificates which such
defaulting Underwriter agreed but failed or refused to purchase on such date;
provided that in no event shall the principal amount of Certificates that any
Underwriter has agreed to purchase pursuant to Section 3 be increased pursuant
to this Section 9 by an amount in excess of one-ninth of such principal amount
of Certificates, without the written consent of such Underwriter, and provided
further that no Underwriter shall be obligated under this Section 9 to purchase
Certificates of a Class that it is not otherwise obligated to purchase under
this Agreement.

      If, on the Closing Date, one of the Underwriters shall fail or refuse to
purchase Certificates that it has agreed to purchase hereunder on such date and
the aggregate principal amount of Certificates with respect to which such
default occurs is more than one-tenth of the aggregate principal amount of
Certificates to be purchased on such date and arrangements satisfactory to the
non-defaulting Underwriter and the Depositor for the purchase of such
Certificates are not made within 36 hours after such default, this Agreement
shall terminate without liability on the part of any non-defaulting Underwriter
or of the Depositor. In any such case either such non-defaulting Underwriter or
the Depositor shall have the right to postpone the Closing Date, but in no event
for longer than seven days, in order that the required changes, if any, in the
Prospectus or in any other documents or arrangements may be effected. Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of such Underwriter under this Agreement.

      10.   Termination of Agreement.

            (a)     Any Underwriter may terminate its obligations under this
Agreement, by notice to the Depositor, at any time at or prior to the Closing
Date if the sale of the Certificates provided for herein is not consummated
because of any failure or refusal on the part of the Depositor to comply in all
material respects with the terms, or to fulfill in all material respects any of
the conditions of, this Agreement, or if for any reason the Depositor shall be
unable to perform in all material respects its obligations under this Agreement.

            (b)     Any Underwriter may terminate its obligations under this
Agreement in the absolute discretion of such Underwriter, by notice given to the
Depositor, if (A) after the execution and delivery of this Agreement and prior
to the Closing Date (i) trading generally shall have been suspended or
materially limited on or by, as the case may be, any of the New York Stock
Exchange, the American Stock Exchange, the National Association of Securities
Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile
Exchange or the Chicago Board of Trade, (ii) trading of any securities of the
Depositor or its affiliates shall have been


                                       25

suspended on any exchange or in any over-the-counter market, (iii) a general
moratorium on commercial banking activities in New York shall have been declared
by either Federal or State of New York authorities, or (iv) there shall have
occurred any outbreak or escalation of hostilities or any change in financial
markets or any calamity or crisis, or any major disruption of settlement or
clearance of securities in the United States that, in the judgment of such
Underwriter, is material and adverse and (B) in the case of any of the events
specified in clauses (A)(i) through (iv) above, such event singly or together
with any other such event, makes it, in the judgment of such Underwriter,
impracticable to market the Certificates on the terms and in the manner
contemplated in the Time of Sale Information and the Prospectus.

            (c)     If any Underwriter terminates its obligations under this
Agreement in accordance with Section 10(a), the Depositor shall reimburse such
Underwriter for all reasonable out-of pocket expenses (including reasonable fees
and disbursements of counsel) that shall have been reasonably incurred by such
Underwriter in connection with the proposed purchase and sale of the
Certificates.

final prospectus supplement unless such changes are material.

(2) The offered certificates will, at all times, accrue interest at a per annum

         COMMERCIAL MORTGAGE PASS-THROUGH CERTIFICATES, SERIES 2007-HQ13
         This free writing prospectus relates to Morgan Stanley Capital I Inc.'s
offering of selected classes of its Series 2007-HQ13 Commercial Mortgage
Pass-Through Certificates and clarifies, updates or adds the following
information as it relates to the related free writing prospectus, dated December
13, 2007:

o         Two mortgage loans, Mortgage Loan No. 55, the Kohls at Redding Hilltop
          Plaza Mortgage Loan, which had an outstanding balance as of the
          cut-off date of $5,300,000, representing 0.5% of the initial
          outstanding pool balance, and Mortgage Loan No. 67, the Stop &
          Shop-Greenfield Mortgage Loan, which had an outstanding balance as of
          the cut-off date of $3,570,522, representing 0.3% of the initial
          outstanding pool balance, have been removed from the mortgage pool.
          This decrease in the number of mortgage loans results in consequential
          changes to the initial certificate balance of each class of offered
          certificates as set forth below and to the other statistical data
          contained in the free writing prospectus dated December 13, 2007, but
          no changes in the statistical data (other than the new certificate
          balances of the offered certificates) are set forth herein because the
          depositor and the mortgage loan sellers have determined that such
          changes are not material;

o         The removal of Mortgage Loan No. 55 means that only one (1) mortgage
          loan, representing 0.8% of the initial outstanding pool balance (and
          representing 1.0% of the initial outstanding loan group 1 balance),
          was originated in December 2007 and has its first due date in February
          2008, and consequently the depositor has agreed to deposit
          approximately $48,897 into the certificate account on the closing date
          (which amount represents one month's interest on the initial principal
          balance of such mortgage loan, and which amount will be distributable
          to certificateholders on the first distribution date in January 2008);
