      to, and agrees with, each Underwriter that:
            (a) A registration statement on Form S-3 (File No. 333-________),
      including a prospectus, has been filed with the Securities and Exchange
      Commission (the "Commission") and has become effective under the
      Securities Act of 1933, as amended (the "Act"). As of the date of each
      Contract of Sale (as defined in the indemnification agreement, dated the
      date hereof (the "Indemnification Agreement") among CWALT,
                                      2
      [CHL] and the other parties named therein) and as of the Closing Date
      (as defined herein), no stop order suspending the effectiveness of such
      registration statement has been issued and no proceedings for that
      purpose have been initiated or to CWALT's knowledge threatened by the
      Commission. The prospectus in the form in which it will be used in
      connection with the offering of the Public Certificates (the "Base
      Prospectus") is proposed to be supplemented by a prospectus supplement
      dated the date hereof relating to the Certificates and, as so
      supplemented, to be filed with the Commission pursuant to Rule 424 under
      the Act. (Such registration statement is hereinafter referred to as the
      "Registration Statement;" such prospectus supplement, as first filed
      with the Commission, is herein referred to as the "Prospectus
      Supplement;" and such prospectus, in the form in which it will first be
      filed with the Commission in connection with the offering of the Public
      Certificates, including documents incorporated therein as of the time of
      such filing and as supplemented by the Prospectus Supplement, is
      hereinafter referred to as the "Prospectus"). Any reference herein to
      the Registration Statement, a preliminary prospectus or the Prospectus
      shall be deemed to refer to and include the documents incorporated by
      reference therein pursuant to Item 12 of Form S-3 which were filed under
      the Securities Exchange Act of 1934, as amended (the "Exchange Act") on
      or before the date on which the Registration Statement, as amended,
      became effective or the issue date of such preliminary prospectus or the
      date on which the Prospectus is filed pursuant to Rule 424(b) under the
      Act, as the case may be; and any reference herein to the terms "amend,"
      "amendment" or "supplement" with respect to the Registration Statement,
      any preliminary prospectus or the Prospectus shall be deemed to refer to
      and include the filing of any document under the Exchange Act after the
      date on which the
                                      3
      Registration Statement became effective or the issue date of any
      preliminary prospectus or the date on which the Prospectus is filed
      pursuant to Rule 424(b) under the Act, as the case may be, deemed to be
      incorporated therein by reference.
            (b) The Registration Statement as of its effective date, as of the
      date of the Prospectus Supplement and as of the date of each Contract of
      Sale conformed and will conform in all material respects to the
      requirements of the Act and the rules and regulations of the Commission
      thereunder applicable to such documents as of such dates. The
      Prospectus, as of its issue date, as of the date of the Prospectus
      Supplement and as revised, amended or supplemented and filed with the
      Commission prior to the termination of the offering of the Public
      Certificates, conformed and will conform in all material respects to the
      requirements of the Act and the rules and regulations of the Commission
      thereunder applicable to such documents as of such respective dates, and
      the Prospectus as revised, amended or supplemented and filed with the
      Commission as of the Closing Date will conform in all material respects
      to the requirements of the Act and the rules and regulations of the
      Commission thereunder applicable to such documents as of the Closing
      Date. The Registration Statement, at the time it became effective and as
      of the date of each Contract of Sale, did not include any untrue
      statement of a material fact or omit to state a material fact required
      to be stated therein or necessary to make the statements therein not
      misleading; and the Prospectus as of the date of the Prospectus
      Supplement, and the Prospectus as revised, amended or supplemented and
      filed prior to the Closing Date, as of the Closing Date, will not
      include any untrue statement of a material fact and will not omit to
      state a material fact required to be stated therein or necessary to make
      the statements therein, in light of the circumstances under which they
                                      4
      were made, not misleading; provided, however, that CWALT makes no
      representations, warranties or agreements as to the information
      contained in or omitted from the Prospectus or any revision or amendment
      thereof or supplement thereto in reliance upon and in conformity with
      information furnished in writing to CWALT by or on behalf of any
      Underwriter or Broker-Dealer (as defined in the Indemnification
      Agreement) specifically for use in connection with the preparation of
      the Prospectus or any revision or amendment thereof or supplement
      thereto, such information being defined in the Indemnification
      Agreement.
            (c) The Issuer Free Writing Prospectus (as defined in the
      Indemnification Agreement) as of its date (the "Start Date") and as of
      each day through the Closing Date, constitutes and will constitute an
      "issuer free writing prospectus" as defined in Rule 433 of the Act and
      does not and will not as of any such time conflict with the information
      in the Registration Statement or the Prospectus. The Issuer Free Writing
      Prospectus has been filed with the Commission as required by Rule 433.
      The Issuer Free Writing Prospectus and the Base Prospectus
      (collectively, the "Disclosure Package") as of the Start Date and as of
      each day through the Closing Date does not and will not include an
      untrue statement of a material fact and does not and will not omit to
      state a material fact necessary to make the statements therein, in light
      of the circumstances under which they were made, not misleading.
            (d) The Seller Mortgage Loan Information (as defined in the
      Indemnification Agreement) as of the date it is forwarded to an
      Underwriter, is accurate in all material respects.
                                      5
            (e) The Public Certificates will conform in all material respects
      to the description thereof contained in the Disclosure Package and the
      Prospectus, and each of the Certificates, when validly authenticated,
      issued and delivered in accordance with the Pooling and Servicing
      Agreement, will be duly and validly issued and outstanding and entitled
      to the benefits of the Pooling and Servicing Agreement. Each Certificate
      of the classes indicated to be "mortgage related securities" under the
      heading "Summary--Legal Investment" in the Prospectus Supplement will,
      when issued, be a "mortgage related security" as such term is defined in
      Section 3(a)(41) of the Exchange Act.
            (f) This Agreement has been duly authorized, executed and
      delivered by CWALT. As of the Closing Date, the Pooling and Servicing
      Agreement, the Indemnification Agreement and each insurance agreement,
      if any, referred to in the Prospectus Supplement (each an "Insurance
      Agreement" and collectively the "Insurance Agreements") between CWALT
      and the third party provider of credit enhancement, if any (the
      "Certificate Insurer"), included in the Trust Fund will have been duly
      authorized, executed and delivered by CWALT and will conform in all
      material respects to the descriptions thereof contained in the
      Disclosure Package and the Prospectus and, assuming the valid execution
      and delivery thereof by the other parties thereto, this Agreement, each
      subsequent supplemental transfer agreement, if any, referred to in the
      Disclosure Package and the Prospectus Supplement (each a "Supplemental
      Transfer Agreement") and the Pooling and Servicing Agreement each will
      constitute a legal, valid and binding agreement of CWALT enforceable in
      accordance with its terms, except as the same may be limited by
      bankruptcy, insolvency, reorganization or other similar laws affecting
      creditors' rights generally and by general principles of equity.
                                      6

      to enter into and perform its obligations under the Pooling and
      Servicing Agreement, each Supplemental Transfer Agreement, the
      Indemnification Agreement, the Insurance Agreements and this Agreement.
            (h) Neither the issuance or delivery of the Certificates, nor the
      consummation of any other of the transactions contemplated herein, nor
      compliance with the provisions of the Pooling and Servicing Agreement,
      the Indemnification Agreement, each Supplemental Transfer Agreement, the
      Insurance Agreements or this Agreement, will conflict with or result in
      the breach of any material term or provision of the certificate of
      incorporation or bylaws of CWALT, and CWALT is not in breach or
      violation of or in default (nor has an event occurred which with notice

      agreement or other evidence of indebtedness or other agreement,
      obligation or instrument to which CWALT is a party or by which it or its
      properties are bound, or (ii) any law, decree, order, rule or regulation
      applicable to CWALT of any court or supervisory, regulatory,
      administrative or governmental agency, body or authority, or arbitrator
      having jurisdiction over CWALT, or its properties, the default in or the
      breach or violation of which would have a material adverse effect on
      CWALT or the Certificates or the ability of CWALT to perform its
      obligations under the Pooling and Servicing Agreement, the
      Indemnification Agreement, each Supplemental Transfer Agreement, the
      Insurance Agreements or this Agreement; and neither the delivery of the
      Certificates, nor
                                      7
      the consummation of any other of the transactions contemplated herein,
      nor the compliance with the provisions of the Pooling and Servicing
      Agreement, the Indemnification Agreement each Supplemental Transfer
      Agreement, the Insurance Agreement or this Agreement will result in such
      a breach, violation or default which would have such a material adverse
      effect.
            (i) No filing or registration with, notice to, or consent,
      approval, authorization or order or other action of any court or
      governmental authority or agency is required for the consummation by

      Transfer Date, as applicable, obtained under the Act, and such
      recordations of the assignment of the Mortgage Loans to the Trustee (to
      the extent such recordations are required pursuant to the Pooling and
      Servicing Agreement) that have not yet been completed.
            (j) There is no action, suit or proceeding before or by any court,
      administrative or governmental agency now pending to which CWALT is a
      party, or to the best of CWALT's knowledge threatened against CWALT
      which could reasonably result individually or in the aggregate in any
      material adverse change in the condition (financial or otherwise),
      earnings, affairs, regulatory situation or business prospects of CWALT
      or could reasonably interfere with or materially and adversely affect
      the consummation of the transactions contemplated in the Pooling and
      Servicing Agreement,

      Servicing Agreement, (1) CWALT will own the Mortgage Loans being
      transferred to the Trust Fund pursuant thereto, free and clear of any

      security interest (collectively, "Liens"), except to the extent

            (n) The transfer of the Mortgage Loans to the Trust Fund at the

      Act;
            (r) CWALT has complied and will comply with the requirements of
      Rule 433 under the Act applicable to the Issuer Free Writing Prospectus,

      price at which each Underwriter will purchase its Underwritten Public
      Certificates shall be as set forth in a separate pricing letter dated
      the date hereof between each such Underwriter and CWALT (each, a
      "Pricing Letter"), and the terms of each such Pricing Letter are hereby
      incorporated herein by reference as if such terms were stated herein in
      their entirety. References herein to this "Agreement" shall include the
      terms of each Pricing Letter.
            3. Delivery and Payment. The Public Certificates shall be

      date and time may be changed by agreement between the Underwriters and
      CWALT (such date and time of delivery of and payment for such Public
      Certificates being referred to herein as the "Closing Date"). Delivery
      of the Underwritten Public Certificates shall be made to each of the
      Underwriters as against their respective payment of the purchase price
      therefor to or upon the order of CWALT in immediately available federal
      funds. The Underwritten Public Certificates shall be registered in such
      names and in such denominations as the respective Underwriters may have
      requested or as required by book-entry registration not less than [two]
      full business days prior to the Closing Date.
            4. Offering by Underwriters. (a) It is understood that the
      Underwriters propose to offer the Underwritten Public Certificates for
      sale as set forth in the Prospectus and that you will not offer, sell or
      otherwise distribute the Underwritten Public Certificates (except for
      the sale thereof in exempt transactions) in any state in which the
      Underwritten Public Certificates are not exempt from registration under
      "blue sky" or state securities laws (except where the Underwritten
      Public Certificates will have been qualified for offering and sale at
      your direction under such "blue sky" or state securities laws).
            (b) Each Underwriter agrees that it shall not enter into any
      Contract of Sale with any investor with respect to any class of
      Underwritten Public Certificates with a minimum denomination of $[1,000]
      until the Base Prospectus and Prospectus Supplement have been delivered
      to such investor.
            (c) In the event that an Underwriter uses a "road show" (as
      defined in Rule 433(h)(4) under the Act) in connection with the offering
      of the Underwritten Public Certificates, the Underwriter agrees that all
      information in such road show shall be
                                      12
      provided orally only and not as a "written communication" (as defined in
      Rule 405 under the Act). Each Underwriter agrees that any slideshow used
      in connection with a road show (i) shall only be provided as part of the
      road show and not separately, (ii) if handed out at any meeting as a
      hard copy, shall be retrieved prior to the end of the meeting and (iii)
      will otherwise be used only in a manner that does cause the slideshow to
      be treated as a "free writing prospectus" (as defined in Rule 405 under
      the Act).
            (d) If any "written communication" (as defined in Rule 405 under
      the Act) in connection with the offering of the Underwritten Public
      Certificates contains an untrue statement of material fact or omits to
      state a material fact necessary to make the statements, in light of the
      circumstances under which they were made, not misleading at the time
      that a Contract of Sale was entered into, when taken together with all
      information that was conveyed to any person with whom a Contract of Sale
      was entered into, then the applicable Underwriter shall provide any such
      person with the following:
                (i) Adequate disclosure of the contractual arrangement;
                (ii) Adequate disclosure of the person's rights under the
            existing Contract of Sale at the time termination is sought;
                (iii) Adequate disclosure of the new information that is
            necessary to correct the misstatements or omissions in the
            information given at the time of the original Contract; and
                (iv) A meaningful ability to elect to terminate or not
            terminate the prior Contract of Sale and to elect to enter into or
            not enter into a new Contract of Sale.
            5. Agreements. CWALT agrees with each Underwriter that:
                                      13
            (a) CWALT will cause the Prospectus to be filed with the
      Commission pursuant to Rule 424 under the Act and, if indicated in the
      Prospectus, within [15] days of the Closing Date, will file a report on
      Form 8-K setting forth specific information concerning the Mortgage
      Loans, and will promptly advise each Underwriter when the Prospectus has
      been so filed, and, prior to the termination of the offering of the
      Public Certificates, will also promptly advise each Underwriter (i) when
      any amendment to the Registration Statement has become effective or any
      revision of or supplement to the Prospectus has been so filed (unless
      such amendment, revision or supplement does not relate to the
      Certificates), (ii) of any request by the Commission for any amendment
      of the Registration Statement or the Prospectus or for any additional
      information (unless such request for additional information does not
      relate to the Certificates), (iii) of any written notification received
      by CWALT of the suspension of qualification of the Public Certificates
      for sale in any jurisdiction or the initiation or threatening of any

      of any stop order suspending the effectiveness of the Registration
      Statement or the institution or to the knowledge of CWALT, the
      threatening of any proceeding for that purpose. CWALT 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. Except as
      otherwise provided in Section 5(b) hereof, CWALT will not file prior to
      the termination of such offering any amendment to the Registration
      Statement or any revision of or supplement to the Prospectus (other than
      any such amendment, revision or supplement which does not relate to the
      Certificates) which shall be disapproved by the Underwriters after
      reasonable notice and review of such filing.
                                      14
            (b) If, at any time when a statutory prospectus relating to the
      Public Certificates is required to be delivered under the Act (i) any
      event occurs as a result of which the Prospectus as then amended or
      supplemented would include 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, or (ii) it shall be necessary to revise, amend or supplement
      the Prospectus to comply with the Act or the rules and regulations of
      the Commission thereunder, CWALT promptly will notify each Underwriter
      and will, upon the request of any Underwriter, or may, after
      consultation with each Underwriter, prepare and file with the Commission
      a revision, amendment or supplement which will correct such statement or
      omission or effect such compliance, and furnish without charge to each
      Underwriter as many copies as such Underwriter may from time to time
      reasonably request of an amended Prospectus or a supplement to the

      compliance.
            (c) If, at any time after the Start Date and prior to the Closing
      Date any event occurs as a result of which the Disclosure Package as

      material fact or omit to state a material fact necessary to make the
      statements therein, in light of the circumstances under which they were
      made, not misleading, or would conflict with the information in the
      Registration Statement, CWALT promptly will notify each Underwriter and
      will, upon the request of any Underwriter, or may, after consultation
      with each Underwriter, prepare and file with the Commission (as may be
      required under the Rules and Regulations) a revision, amendment or
      supplement which will correct such conflict, statement or omission, and
                                      15
      furnish without charge to each Underwriter as many copies as such
      Underwriter may from time to time reasonably request of such revision,
      amendment or supplement.

      counsel for the Underwriters an agreed upon procedures letter from

      in the Indemnification Agreement) furnished to CWALT by an Underwriter,
      to the extent required under the Act, prior to the time of filing of the
      Prospectus as provided in the Indemnification Agreement and will include
      therein all materials so furnished. In addition, CWALT will file all

                                      17
            (i) If by the [third] anniversary (the "Renewal Deadline") of the
      initial effective date of the Registration Statement, any of the Public
      Certificates remain unsold by the Underwriters and the Underwriters have
      so notified CWALT in writing at least [90] days prior to the Renewal
      Deadline, CWALT will file, if it has not already done so and is eligible
      to do so, a new shelf registration statement relating to the Public
      Certificates, in a form satisfactory to the Underwriters and will use
      its best efforts to cause such registration statement to be declared
      effective within [180] days after the Renewal Deadline. CWALT will take
      all other action necessary or appropriate to permit the public offering
      and sale of the Public Certificates to continue as contemplated in the
      expired registration statement relating to the Public Certificates.
      References herein to the Registration Statement shall include such new
      shelf registration statement.
            6. Conditions to the Obligations of Underwriters. The obligation
      of each Underwriter to purchase the Underwritten Public Certificates to

      respects of the representations and warranties on the part of CWALT
      contained herein as of the date hereof and as of the Closing Date, to
      the accuracy of the statements of CWALT made in any officer's

            Registration Statement shall have been issued and no proceedings
            for that purpose shall have been instituted and be pending or

                                      18
            shall have been filed or mailed for filing with the Commission not
            later than required pursuant to the rules and regulations of the
            Commission.
                  (b) CWALT shall have furnished to the Underwriters a
            certificate, dated the Closing Date, of CWALT, signed by a vice
            president of CWALT, to the effect that the signer of such
            certificate has carefully examined the Registration Statement, the
            Prospectus and this Agreement and that:
                  (i) The representations and warranties of CWALT herein are
            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, and

            conditions on its part to be performed or satisfied at or prior to
            the Closing Date;
                  (ii) No stop order suspending the effectiveness of the
            Registration Statement has been issued, and no proceedings for

                  (iii) Nothing has come to the attention of such person that
            would lead him to believe that the Prospectus at the date thereof
            and at the date hereof contained or contains any untrue statement
            of a material fact or omitted or omits to state any material fact
            necessary in order to make the statements therein, in the light of
            the circumstances under which they were made, not misleading.
                  (c) [CHL] shall have furnished to the Underwriters a
            certificate, dated the Closing Date, of [CHL], signed by a vice
            president or an assistant vice president of [CHL], to the effect

            examined the Prospectus and nothing has come to the attention of
            such person that would lead him to believe that the Prospectus
            contains any untrue statement of a material fact with respect to
            [CHL] or the Mortgage Loans or omits to state any material fact
            with respect to [CHL] or the Mortgage Loans necessary in order to

            Agreement, the Insurance Agreements or this Agreement.
                  (d) CWALT shall have furnished to you an opinion, dated the
            Closing Date, of ____________________, special counsel to CWALT,
            to the effect that:
                  (i) The Registration Statement and any amendments thereto
            have become effective under the Act; to the best knowledge of such
            counsel, no stop order suspending the effectiveness of the
            Registration Statement has been issued and not withdrawn, no
            proceedings for that purpose have been instituted or threatened
            and not terminated; and the Registration Statement, the Prospectus
            and each amendment or supplement thereto, as of their respective
            initial effective or issue dates (other than the financial and
            statistical information contained therein, complied as to form in
            all material respects with the applicable requirements of the Act
            and the rules and regulations thereunder;
                  (ii) To the best knowledge of such counsel, there are no
            material contracts, indentures or other documents of a character
            required to be described or referred to in the Registration
            Statement or the Prospectus or to be filed as
                                      20
            exhibits to the Registration Statement other than those described
            or referred to therein or filed or incorporated by reference as
            exhibits thereto;
                  (iii) Assuming that the Pooling and Servicing Agreement and
            this Agreement have each been duly authorized, executed and
            delivered by the parties thereto, each constitutes a valid, legal
            and binding agreement of CWALT, the Master Servicer and [CHL] in
            the case of the Pooling and Servicing Agreement and of CWALT in
            the case of this Agreement and the Insurance Agreements
            enforceable against CWALT, the Master Servicer or [CHL], as
            applicable, in accordance with its terms, subject, as to
            enforceability, to bankruptcy, insolvency, reorganization,
            moratorium or other similar laws affecting creditors' rights
            generally and to general principles of equity regardless of
            whether enforcement is sought in a proceeding in equity or at law;
                  (iv) Assuming that the Certificates have been duly and
            validly authorized, executed and authenticated in the manner
            contemplated in the Pooling and Servicing Agreement, when
            delivered and paid for by you as provided in this Agreement, the
            Certificates will be validly issued and outstanding and entitled
            to the benefits of the Pooling and Servicing Agreement;
                  (v) The Certificates and the Pooling and Servicing Agreement
            conform in all material respects to the descriptions thereof
            contained in the Prospectus;
                  (vi) The statements in the Prospectus Supplement, under the
            headings "Material Federal Income Tax Consequences," "ERISA
            Considerations" and "Summary--Legal Investment," and in the
            Prospectus under "Material Federal
                                      21
            Income Tax Consequences," "ERISA Considerations," and "Legal
            Investment" to the extent that they constitute matters of New York
            or federal law or legal conclusions with respect thereto, have
            been reviewed by such counsel and are correct in all material
            respects;
                  (vii) The Certificates indicated under the heading
            "Summary--Legal Investment" in the Prospectus Supplement to be
            "mortgage related securities" will be mortgage related securities,
            as defined in Section 3(a)(41) of the Exchange Act, so long as
            such Certificates are rated in one of the two highest rating
            categories by at least one nationally recognized statistical
            rating organization;
                  (viii) The Pooling and Servicing Agreement is not required
            to be qualified under the Trust Indenture Act of 1939, as amended,
            and the Trust Fund created by the Pooling and Servicing Agreement
            is not required to be registered under the Investment Company Act
            of 1940, as amended; and
                  (ix) Each REMIC as described in the Pooling and Servicing
            Agreement will qualify as a "real estate mortgage investment
            conduit" ("REMIC") within the meaning of Section 860D of the
            Internal Revenue Code of 1986, as amended (the "Code"), (b) the
            Regular Certificates will be treated as regular interests in the
            Master REMIC, and (c) the Class A-R Certificate will represent
            ownership of the sole class of residual interest in each REMIC
            created pursuant to the Pooling and Servicing Agreement.
            Such counsel shall also state that nothing has come to its
attention that would lead such counsel to believe that the Registration
Statement, at the time it initially became effective, contained an untrue
statement of a material fact or omitted to state a material fact required to
be
                                      22
stated therein or necessary to make the statements therein not misleading or
that the Prospectus, as of the date of the Prospectus Supplement, and on the
Closing Date, contained or contains an untrue statement of a material fact or
omitted or omits 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; it being understood that such counsel need express no
view as to (i) financial and statistical information contained therein or (ii)
any description in the Prospectus of any third party providing credit
enhancement to the Certificates.
            Such opinion may express its reliance as to factual matters on the
representations and warranties made by, and on certificates or other documents
furnished by officers of, the parties to this Agreement and the Pooling and
Servicing Agreement. Such opinion may be qualified as an opinion only on the
laws of the State of New York and the federal law of the United States. To the
extent that such firm relies upon the opinion of other counsel in rendering
any portion of its opinion, the opinion of such other counsel shall be
attached to and delivered with the opinion of such firm that is delivered to
you.
                  (e) CWALT shall have furnished to the Underwriters an
            opinion, dated the Closing Date, of counsel to CWALT (who may be
            an employee of CWALT or of an affiliate of CWALT), to the effect
            that:
                  (i) CWALT has been duly incorporated, is validly existing as
            a corporation in good standing under the laws of the State of
            Delaware and is duly qualified to do business in, and is in good

            California;
                  (ii) The Certificates have been duly authorized and executed
            and, assuming authentication and delivery in the manner
            contemplated in the Pooling

            and Servicing Agreement, are validly issued and outstanding, and
            upon delivery by CWALT of the Certificates to be purchased by the
            Underwriters and payment by the Underwriters of the purchase price
            therefor in the manner contemplated by this Agreement, the
            Underwriters will acquire such Certificates free and clear of any
            lien, pledge, encumbrance or other security interest other than
            one created or granted by any Underwriter;
                  (iii) The Pooling and Servicing Agreement has been duly
            authorized, executed and delivered by CWALT;
                  (iv) This Agreement, the Insurance Agreements and the
            Indemnification Agreement have each been duly authorized, executed
            and delivered by CWALT;
                  (v)  No consent, approval, authorization or order of any
            [California] or federal governmental agency or body or, to the
            best knowledge of such counsel, any [California] or federal court
            is required for the consummation by CWALT of the transactions
            contemplated by the terms of this Agreement, the Insurance
            Agreements or the Pooling and Servicing Agreement except such as
            may be required under the "blue sky" or state securities laws of
            any jurisdiction in connection with the offering, sale or
            acquisition of the Certificates, any recordations of the
            assignment of the mortgage loans to the Trustee (to the extent
            such recordations are required pursuant to the Pooling and
            Servicing Agreement) that have not yet been completed and such
            other approvals as have been obtained;
                  (vi) The sale of the Certificates to be purchased by the
            Underwriters pursuant to this Agreement and the consummation of
            any of the transactions
                                      24
            contemplated by the terms of the Pooling and Servicing Agreement,
            the Indemnification Agreement or this Agreement do not conflict
            with or result in a breach or violation of any material term or
            provision of, or constitute a default under, the certificate of
            incorporation of CWALT, or any indenture or other agreement or
            instrument to which CWALT is a party or by which it is bound, or
            any [California] or federal statute or regulation applicable to
            CWALT or, to the best knowledge of such counsel, an order or
            decree of any [California] or federal court, regulatory body,
            administrative agency or governmental body having jurisdiction
            over CWALT; and
                  (vii) There are no legal or governmental actions,
            investigations or proceedings pending to which CWALT is a party,
            or, to the best knowledge of such counsel, threatened against
            CWALT, (A) asserting the invalidity of this Agreement, the Pooling
            and Servicing Agreement, the Indemnification Agreement, the
            Insurance Agreements or the Certificates, (B) seeking to prevent
            the issuance of the Certificates or the consummation of any of the
            transactions contemplated by this Agreement, the Pooling and
            Servicing Agreement, the Indemnification Agreement or the
            Insurance Agreements, (C) which might materially and adversely
            affect the performance by CWALT of its obligations under, or the
            validity or enforceability of, this Agreement, the Pooling and
            Servicing Agreement, the Indemnification Agreement, the Insurance
            Agreements or the Certificates or (D) seeking to affect adversely
            the federal income tax attributes of the Certificates as described
            in the Prospectus under the heading "Material Federal Income Tax
            Consequences." For purposes of the foregoing,
                                      25
            such counsel may state that it has not regarded any legal or
            governmental actions, investigations or proceedings to be
            "threatened" unless the potential litigant or governmental
            authority has manifested to the legal department of CWALT a
            present intention to initiate such proceedings.
            Such opinion may express its reliance as to factual matters on the
representations and warranties made by, and on certificates or other documents
furnished by officers of, the parties to this Agreement, the Insurance
Agreements, the Indemnification Agreement and the Pooling and Servicing
Agreement. Such opinion may assume the due authorization, execution and
delivery of the instruments and documents referred to therein by the parties
thereto other than CWALT or its affiliates. Such opinion may be qualified as
an opinion only on the laws of the States of Delaware and California and the
federal law of the United States. To the extent that such counsel relies upon
the opinion of other counsel in rendering any portion of its opinion, the
opinion of such other counsel shall be attached to and delivered with the
opinion of such counsel that is delivered to the Underwriters.
            (f) [CHL] shall have furnished to the Underwriters an opinion,
      dated the Closing Date, of counsel to [CHL] (who may be an employee of
      [CHL]), to the effect that:
                  (i) [CHL] has been duly incorporated and is validly existing
            as a corporation in good standing under the laws of the State of
            [New York];
                  (ii) The Pooling and Servicing Agreement and the Insurance
            Agreements have each been duly authorized, executed and delivered
            by [CHL];
                  (iii) No consent, approval, authorization or order of any
            [California] or federal governmental agency or body or, to the
            best knowledge of such counsel,
                                      26
            any [California] or federal court is required for the consummation
            by [CHL] of the transactions contemplated by the terms of the
            Pooling and Servicing Agreement except any such as may be required
            under the "blue sky" or state securities laws of any jurisdiction
            in connection with the offering, sale or acquisition of the
            Certificates, any recordations of the assignment of the Mortgage
            Loans evidenced by the Certificates to the Trustee (to the extent
            such recordations are required pursuant to the Pooling and
            Servicing Agreement) that have not yet been completed and any
            approvals as have been obtained;
                  (iv) The consummation of any of the transactions
            contemplated by the terms of the Pooling and Servicing Agreement
            or the Insurance Agreements do not conflict with or result in a
            breach or violation of any material term or provision of, or
            constitute a default under, the charter or bylaws of [CHL], or, to
            the best knowledge of such counsel, any indenture or other
            agreement or instrument to which [CHL] is a party or by which it
            is bound, any [New York] or federal law, statute or regulation
            applicable to [CHL] or, to the best knowledge of such counsel, any
            order of any [California] or federal court, regulatory body,
            administrative agency or governmental body having jurisdiction
            over [CHL]; and
                  (v) There are no legal or governmental actions,
            investigations or proceedings pending to which [CHL] is a party,
            or, to the best knowledge of such counsel, threatened against
            [CHL], (A) asserting the invalidity of the Pooling and Servicing
            Agreement or the Insurance Agreements or (B) which might
            materially and adversely affect the performance by [CHL] of its
            obligations under, or the validity or enforceability of, the
            Pooling and Servicing Agreement or the
                                      27
            Insurance Agreements. For purposes of the foregoing, such counsel
            may state that it has not regarded any legal or governmental
            actions, investigations or proceedings to be "threatened" unless
            the potential litigant or governmental authority has manifested to
            the legal department of [CHL] a present intention to initiate such
            proceedings.
            Such opinion may express its reliance as to factual matters on the
representations and warranties made by, and on certificates or other documents
furnished by officers of, the parties to the Pooling and Servicing Agreement.
Such opinion may assume the due authorization, execution and delivery of the
instruments and documents referred to therein by the parties thereto other
than [CHL]. Such opinion may be qualified as an opinion only on the laws of
the Incorporation State and the federal law of the United States and, with
respect to the opinions set forth in paragraph (f)(ii) above, the laws of the
State of [New York]. To the extent that such counsel relies upon the opinion
of other counsel in rendering any portion of its opinion, the opinion of such
other counsel shall be attached to and delivered with the opinion of such
counsel that is delivered to the Underwriters.
            (g)  The Master Servicer shall have furnished to the Underwriters
      an opinion, dated the Closing Date, of counsel to the Master Servicer
      (who may be an employee of the Master Servicer), to the effect that:
                 (i) The Master Servicer has been duly formed and is validly
            existing as a limited partnership in good standing under the laws
            of the State of [Texas];
                 (ii) The Pooling and Servicing Agreement has been duly
            authorized, executed and delivered by the Master Servicer;
                                      28
                  (iii) No consent, approval, authorization or order of any
            [California] or federal governmental agency or body or, to the
            best knowledge of such counsel, any [California] or federal court
            is required for the consummation by the Master Servicer of the
            transactions contemplated by the terms of the Pooling and
            Servicing Agreement except any such as may be required under the
            "blue sky" or state securities laws of any jurisdiction in
            connection with the offering, sale or acquisition of the
            Certificates, any recordations of the assignment of the Mortgage
            Loans evidenced by the Certificates to the Trustee (to the extent
            such recordations are required pursuant to the Pooling and
            Servicing Agreement) that have not yet been completed and any
            approvals as have been obtained;
                  (iv) The consummation of any of the transactions
            contemplated by the terms of the Pooling and Servicing Agreement
            does not conflict with or result in a breach or violation of any
            material term or provision of, or constitute a default under, the
            certificate of limited partnership or the partnership agreement of
            the Master Servicer, or, to the best knowledge of such counsel,
            any agreement or instrument to which the Master Servicer is a
            party or by which it is bound, any [California] or federal statute
            or regulation applicable to the Master Servicer or, to the best
            knowledge of such counsel, any order of any [California] or
            federal court, regulatory body, administrative agency or
            governmental body having jurisdiction over the Master Servicer;
            and
                  (v) There are no legal or governmental actions,
            investigations or proceedings pending to which the Master Servicer
            is a party, or, to the best knowledge of such counsel, threatened
            against the Master Servicer, (A) asserting
                                      29
            the invalidity of the Pooling and Servicing Agreement (B) which
            might materially and adversely affect the performance by the
            Master Servicer of its obligations under, or the validity or
            enforceability of, the Pooling and Servicing Agreement. For
            purposes of the foregoing, such counsel may state that it has not
            regarded any legal or governmental actions, investigations or
            proceedings to be "threatened" unless the potential litigant or
            governmental authority has manifested to the legal department of
            the Master Servicer a present intention to initiate such
            proceedings.
                  (vi) Such opinion may express its reliance as to factual
            matters on the representations and warranties made by, and on
            certificates or other documents furnished by officers of, the
            parties to the Pooling and Servicing Agreement. 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 Master Servicer. Such opinion may be
            qualified as an opinion only on the laws of the State of
            [California] and the federal law of the United States. To the
            extent that such counsel relies upon the opinion of other counsel
            in rendering any portion of its opinion, the opinion of such other
            counsel shall be attached to and delivered with the opinion of
            such counsel that is delivered to the Underwriters.
            (h) Each party, if any, providing credit enhancement to the
      Certificates shall have furnished to the Underwriters an opinion, dated
      the Closing Date, of its counsel, with respect to the Registration
      Statement and the Prospectus, and such other related matters, in the
      form previously agreed to by such provider and the Underwriters.
            (i) The Underwriters shall have received from their counsel such
      opinion or opinions, dated the Closing Date, with respect to the
      issuance and sale of the Public
                                      30
      Certificates, the Registration Statement and the Prospectus, and such
      other related matters as you may reasonably require.
            (j) CWALT's independent accountants, __________________________,
      shall have furnished to the Underwriters a letter or letters addressed
      to the Underwriters and dated as of or prior to the date of first use of
      the Prospectus Supplement in the form and reflecting the performance of
      the procedures previously agreed to by CWALT and the Underwriters.
            (k) 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 CWALT which in your reasonable
      judgment 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
      Prospectus.
            (l) The Public Certificates shall be rated not lower than the
      required ratings set forth under the heading "Ratings" in the Prospectus
      Supplement, such ratings shall not have been rescinded and no public
      announcement shall have been made that any such required rating of the
      Certificates has been placed under review (otherwise than for possible
      upgrading).
            (m) The Underwriters shall have received copies of any opinions of
      counsel to CWALT supplied to the rating organizations 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.
                                      31
            (n) All Classes of Certificates being publicly offered by the
      Underwriters or privately placed by the Purchaser shall have been issued
      and paid for pursuant to the terms of this Agreement and the Purchase
      Agreement, respectively.
            (o) The Trustee shall have furnished to the Underwriters an
      opinion dated the Closing Date, of counsel to the Trustee (who may be an
      employee of the Trustee), to the effect that:
                  (i) The Trustee has full corporate power and authority to
            execute and deliver the Pooling and Servicing Agreement and to
            perform its obligations thereunder and to execute, countersign and
            deliver the Certificates.
                  (ii) The Pooling and Servicing Agreement has been duly
            authorized, executed and delivered by the Trustee.
                  (iii) In the event that the Master Servicer defaults in its
            obligation to make Advances pursuant to the Pooling and Servicing
            Agreement, the Trustee is not, as of the date hereof, prohibited
            by any provision of its articles of incorporation or by-laws from
            assuming, pursuant to the Pooling and Servicing Agreement, the
            obligation to make such Advances.
                  (iv) The Pooling and Servicing Agreement is a legal, valid
            and binding obligation of the Trustee, enforceable against the
            Trustee in accordance with its terms, subject to applicable
            bankruptcy, insolvency, reorganization, moratorium, receivership,
            conservatorship and similar laws affecting the rights of creditors
            generally, and subject, as to enforceability, to general
            principles of equity, regardless of whether such enforcement is
            considered in a proceeding at law or equity.
                                      32
            Such opinion may express its reliance as to factual matters on the
representations and warranties made by, and on certificates or other documents
furnished by officers of, the parties to the Pooling and Servicing Agreement.
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 Trustee or its affiliates. Such opinion may be qualified as an
opinion only on the laws of the State of New York and the federal law of the
United States. To the extent that such counsel relies upon the opinion of
other counsel in rendering any portion of its opinion, the opinion of such
other counsel shall be attached to and delivered with the opinion of such
counsel that is delivered to the Underwriters.
            (p) CWALT shall have furnished to the Underwriters such further
      information, certificates and documents as the Underwriters may
      reasonably have requested, and all proceedings in connection with the
      transactions contemplated by this Agreement and all documents incident
      hereto shall be in all material respects reasonably satisfactory in form
      and substance to the Underwriters and their counsel.
            (q) The Indemnification Agreement shall have been executed and
      delivered.
            (r) The Underwriters shall have received an opinion as to certain
      matters regarding the seller(s) other than [CHL] in form and substance
      reasonably satisfactory to the Underwriters and their counsel.
            (s) If any of the conditions specified in this Section 6 shall not
      have been fulfilled in all material respects when and as provided in
      this Agreement, this Agreement and all obligations of an Underwriter
      hereunder may be canceled at, or at any time prior to, the Closing Date
      by such Underwriter. Notice of such cancellation shall be given to CWALT
      in writing, or by telephone or telegraph confirmed in writing.
                                      33
            7. Termination. This Agreement shall be subject to termination in
your absolute discretion, by notice given to CWALT prior to delivery of and
payment for the Underwritten Public Certificates, if prior to such time (i)
trading in securities generally on the New York Stock Exchange shall have been
suspended or materially limited, (ii) a general moratorium on commercial
banking activities in [New York] shall have been declared by either Federal or
[New York] State authorities, or (iii) there shall have occurred any material
outbreak or escalation of hostilities or other calamity or crisis the effect
of which on the financial markets is such as to make it, in your judgment
after consultation with CWALT, impracticable to market the Public Certificates
on the terms specified in this Agreement.
            8. Representations and Indemnities to Survive. The respective
agreements, representations, warranties, indemnities and other statements of
CWALT and its officers and of each Underwriter set forth in or made pursuant
to this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or CWALT, and will
survive delivery of and payment for the Underwritten Public Certificates. The
provisions of Section 5(f) and Section 9 hereof shall survive the termination
or cancellation of this Agreement.
            9. Reimbursement of Underwriter Expenses. If for any reason, other
than default by any Underwriter in its obligation to purchase the Underwritten
Public Certificates or termination by any Underwriter pursuant to Section 7
hereof, the Underwritten Public Certificates are not delivered by or on behalf
of CWALT as provided herein, CWALT will reimburse each Underwriter for all
out-of-pocket expenses of such Underwriter, including reasonable fees and
disbursements of its counsel, reasonably incurred by such Underwriter in
making preparations for the purchase, sale and delivery of the Underwritten
Public Certificates,
                                      34
but CWALT shall then be under no further liability to any Underwriter with
respect to the Underwritten Public Certificates, except as provided in Section
5(f) hereof.
            10. Successors. This Agreement will inure to the benefit of and be

construed in accordance with the laws of the State of New York.
            12. Miscellaneous. Time shall be of the essence of this Agreement.
This Agreement supersedes all prior or contemporaneous agreements and
understandings relating to the subject matter hereof, other than the
Indemnification Agreement. Neither this Agreement nor any term hereof may be
changed, waived, discharged or terminated except by a writing signed by the
party against whom enforcement of such change, waiver, discharge or
termination is sought. This Agreement may be signed in any number of
counterparts, each of which shall be deemed an original, which taken together
shall constitute one and the same instrument.
            13. Notices. All communications hereunder shall be in writing and
effective only on receipt and, if sent to an Underwriter, shall be delivered
