                                WITNESSETH THAT

            In consideration of the mutual agreements herein contained, the
parties hereto agree as follows:


                             PRELIMINARY STATEMENT

            The Depositor is the owner of the Trust Fund that is hereby
conveyed to the Trustee in return for the Certificates. For federal income tax
purposes, the Trustee shall treat the Trust Fund as consisting of, among other
things, a trust (the "ES Trust") beneath which are two real estate mortgage
investment conduits (or in the alternative, the "Lower Tier REMIC" and the
"Master REMIC") and shall make all elections as necessary for such treatment.
The Lower Tier REMIC will hold all the assets of the Trust Fund and will issue
several classes of uncertificated Lower Tier REMIC Interests. The Class
LTR-A-R Interest is hereby designated as the residual interest in the Lower
Tier REMIC and each other Lower Tier REMIC Interest is hereby designated as a
regular interest in the Lower Tier REMIC. The Master REMIC will hold all the
regular interests in the Lower Tier REMIC and will issue several classes of
uncertificated Master REMIC Interests. The Class MR-A-R Interest is hereby
designated as the residual interest in the Master REMIC and each other Master
REMIC Interest is hereby designated as a regular interest in the Master REMIC.
The "latest possible maturity date," for federal income tax purposes, of all
REMIC regular interests created hereby will be the Latest Possible Maturity
Date.

            The Corridor Contracts, the Supplemental Interest Trust and the
Corridor Contract Reserve Fund will not form part of any REMIC.

hereof, hereby sells, transfers, assigns, sets over and otherwise conveys to
the Depositor, without recourse, all its respective right, title and interest
in and to the related Mortgage Loans, including all interest and principal
received or receivable by such Seller, on or with respect to the Mortgage
Loans after the Cut-off Date and all interest and principal payments on the
related Mortgage Loans received prior to the Cut-off Date in respect of
installments of interest and principal due thereafter, but not including

Granada Mortgage Loans, Park Monaco Mortgage Loans and Park Sienna Mortgage
Loans), such delivery may take place within thirty (30) days following the
Closing Date). Such delivery of the Mortgage Files shall be made against
payment by the Depositor of the purchase price, previously agreed to by the
Sellers and Depositor, for the Mortgage Loans. With respect to any Mortgage
Loan that does not have a first payment date on or before the Due Date in the
month of the first Distribution Date, Countrywide shall deposit into the
Distribution Account on or before the Distribution Account Deposit Date
relating to the first Distribution Date, an amount equal to one month's
interest at the related Adjusted Mortgage Rate on the Cut-off Date Principal
Balance of such Mortgage Loan.

            (b) Immediately upon the conveyance of the Mortgage Loans referred
to in clause (a), the Depositor sells, transfers, assigns, sets over and
otherwise conveys to the Trustee for the benefit of the Certificateholders,
without recourse, all the right, title and interest of the Depositor in and to
the Trust Fund together with the Depositor's right to require each Seller to
cure any breach of a representation or warranty made herein by such Seller, or
to repurchase or substitute for any affected Mortgage Loan in accordance
herewith.

            (c) In connection with the transfer and assignment set forth in
clause (b) above, the Depositor has delivered or caused to be delivered to the
Trustee (or, in the case of the Delay Delivery Mortgage Loans, will deliver or
cause to be delivered to the Trustee within thirty (30) days following the
Closing Date) for the benefit of the Certificateholders the following
documents or instruments with respect to each Mortgage Loan so assigned:

             (i) (A) the original Mortgage Note endorsed by manual or facsimile
      signature in blank in the following form: "Pay to the order of
      ____________ without recourse," with all intervening endorsements
      showing a complete chain of endorsement from the originator to the
      Person endorsing the Mortgage Note (each such endorsement being
      sufficient to transfer all right, title and interest of the party so
      endorsing, as noteholder or assignee thereof, in and to that Mortgage
       Note); or

                  (B) with respect to any Lost Mortgage Note, a lost note
            affidavit from Countrywide stating that the original Mortgage Note
            was lost or destroyed, together with a copy of such Mortgage Note;


                                      II-1

                  (ii) except as provided below and for each Mortgage Loan
            that is not a MERS Mortgage Loan, the original recorded Mortgage

            (or, in the case of a Mortgage for which the related Mortgaged
            Property is located in the Commonwealth of Puerto Rico, a true
            copy of the Mortgage certified as such by the applicable notary)
            and in the case of each MERS Mortgage Loan, the original Mortgage,
            or a copy of such mortgage, with recording information, noting the
            presence of the MIN of the Mortgage Loans and either language
            indicating that the Mortgage Loan is a MOM Loan if the Mortgage
            Loan is a MOM Loan or if the Mortgage Loan was not a MOM Loan at
            origination, the original Mortgage and the assignment thereof to
            MERS, with evidence of recording indicated thereon, or a copy of
            the Mortgage certified by the public recording office in which
            such Mortgage has been recorded;

                  (iii) in the case of each Mortgage Loan that is not a MERS
            Mortgage Loan, a duly executed assignment of the Mortgage, or a
            copy of such assignment, with recording information, (which may be
            included in a blanket assignment or assignments), together with,
            except as provided below, all interim recorded assignments of such
            mortgage or a copy of such assignment, with recording information,
            (each such assignment, when duly and validly completed, to be in
            recordable form and sufficient to effect the assignment of and
            transfer to the assignee thereof, under the Mortgage to which the
            assignment relates); provided that, if the related Mortgage has
            not been returned from the applicable public recording office,
            such assignment of the Mortgage may exclude the information to be
            provided by the recording office; provided, further, that such
            assignment of Mortgage need not be delivered in the case of a
            Mortgage for which the related Mortgaged Property is located in
            the Commonwealth of Puerto Rico;

                  (iv) the original or copies of each assumption,
            modification, written assurance or substitution agreement, if any;

                  (v) except as provided below, the original or duplicate
            original lender's title policy or a printout of the electronic
            equivalent and all riders thereto; and

                        (A) The Coop Shares, together with a stock power in
                  blank;

                        (B) The executed Security Agreement;

                         (C) The executed Proprietary Lease;

                        (D) The executed Recognition Agreement;

                        (E) The executed UCC-1 financing statement with
                  evidence of recording thereon which have been filed in all
                  places required to perfect the Seller's interest in the Coop
                  Shares and the Proprietary Lease; and

                        (F) The executed UCC-3 financing statements or other
                  appropriate UCC financing statements required by state law,
                  evidencing a complete and unbroken line from the mortgagee
                  to the Trustee with evidence of recording thereon (or in a
                  form suitable for recordation).


                                     II-2
<PAGE>


            In addition, in connection with the assignment of any MERS
Mortgage Loan, each Seller agrees that it will cause, at the Trustee's
expense, the MERS(R) System to indicate that the Mortgage Loans sold by such
Seller to the Depositor have been assigned by that Seller to the Trustee in
accordance with this Agreement for the benefit of the Certificateholders by
including (or deleting, in the case of Mortgage Loans which are repurchased in
accordance with this Agreement) in such computer files the information
required by the MERS(R) System to identify the series of the Certificates
issued in connection with such Mortgage Loans. Each Seller further agrees that
it will not, and will not permit the Master Servicer to, and the Master
Servicer agrees that it will not, alter the information referenced in this
paragraph with respect to any Mortgage Loan sold by such Seller to the
Depositor during the term of this Agreement unless and until such Mortgage
Loan is repurchased in accordance with the terms of this Agreement.

            In the event that in connection with any Mortgage Loan that is not
a MERS Mortgage Loan the Depositor cannot deliver (a) the original recorded
Mortgage, or a copy of such Mortgage, with recording information, (b) all
interim recorded assignments, or a copy of such assignments, with recording
information or (c) the lender's title policy or a copy of the lender's title
policy (together with all riders thereto) satisfying the requirements of
clause (ii), (iii) or (v) above, respectively, concurrently with the execution
and delivery of this Agreement because such document or documents have not
been returned from the applicable public recording office in the case of
clause (ii) or (iii) above, or because the title policy has not been delivered
to either the Master Servicer or the Depositor by the applicable title insurer
in the case of clause (v) above, the Depositor shall promptly deliver to the
Trustee, in the case of clause (ii) or (iii) above, such original Mortgage or
a copy of such Mortgage, with recording information, or such interim
assignment or a copy of such assignment, with recording information, as the
case may be, with evidence of recording indicated thereon upon receipt thereof
from the public recording office, or a copy thereof, certified, if
appropriate, by the relevant recording office, but in no event shall any such
delivery of the original Mortgage and each such interim assignment or a copy
thereof, certified, if appropriate, by the relevant recording office, be made
later than one year following the Closing Date, or, in the case of clause (v)
above, no later than 120 days following the Closing Date; provided, however,
in the event the Depositor is unable to deliver by such date each Mortgage and
each such interim assignment by reason of the fact that any such documents
have not been returned by the appropriate recording office, or, in the case of
each such interim assignment, because the related Mortgage has not been
returned by the appropriate recording office, the Depositor shall deliver such
documents to the Trustee as promptly as possible upon receipt thereof and, in
any event, within 720 days following the Closing Date. The Depositor shall
forward or cause to be forwarded to the Trustee (a) from time to time
additional original documents evidencing an assumption or modification of a
Mortgage Loan and (b) any other documents required to be delivered by the
Depositor or the Master Servicer to the Trustee. In the event that the
original Mortgage is not delivered and in connection with the payment in full
of the related Mortgage Loan and the public recording office requires the
presentation of a "lost instruments affidavit and indemnity" or any equivalent
document, because only a copy of the Mortgage can be delivered with the
instrument of satisfaction or reconveyance, the Master Servicer shall execute
and deliver or cause to be executed and delivered such a document to the
public recording office. In the case where a public recording office retains
the original recorded Mortgage or in the case where a Mortgage is lost after
recordation in a public recording office, Countrywide shall deliver to the
Trustee a copy of such Mortgage certified by such public recording office to
be a true and complete copy of the original recorded Mortgage.

            As promptly as practicable subsequent to such transfer and
assignment, and in any event, within one-hundred and twenty (120) days after
such transfer and assignment, the Trustee shall (A) as the assignee thereof,
affix the following language to each assignment of Mortgage: "CWALT Series
2007-5CB, The Bank of New York, as trustee", (B) cause such assignment to be
in proper form for recording in the appropriate public office for real
property records and (C) cause to be delivered for recording in the


                                     II-3
<PAGE>


appropriate public office for real property records the assignments of the
Mortgages to the Trustee, except that, (i) with respect to any assignments of
Mortgage as to which the Trustee has not received the information required to
prepare such assignment in recordable form, the Trustee's obligation to do so
and to deliver the same for such recording shall be as soon as practicable
after receipt of such information and in any event within thirty (30) days
after receipt thereof and (ii) the Trustee need not cause to be recorded any
assignment which relates to a Mortgage Loan, the Mortgaged Property and
Mortgage File relating to which are located in any jurisdiction (including
Puerto Rico) under the laws of which the recordation of such assignment is not
necessary to protect the Trustee's and the Certificateholders' interest in the
related Mortgage Loan as evidenced by an opinion of counsel delivered by
Countrywide to the Trustee within 90 days of the Closing Date (which opinion
may be in the form of a "survey" opinion and is not required to be delivered
by counsel admitted to practice law in the jurisdiction as to which such legal
opinion applies).

            In the case of Mortgage Loans that have been prepaid in full as of
the Closing Date, the Depositor, in lieu of delivering the above documents to
the Trustee, will deposit in the Certificate Account the portion of such
payment that is required to be deposited in the Certificate Account pursuant
to Section 3.05 hereof.

            Notwithstanding anything to the contrary in this Agreement, within
thirty (30) days after the Closing Date, Countrywide (on its own behalf and on
behalf of Park Granada, Park Monaco and Park Sienna) shall either (i) deliver
to the Depositor, or at the Depositor's direction, to the Trustee or other
designee of the Depositor the Mortgage File as required pursuant to this
Section 2.01 for each Delay Delivery Mortgage Loan or (ii) either (A)
substitute a Substitute Mortgage Loan for the Delay Delivery Mortgage Loan or
(B) repurchase the Delay Delivery Mortgage Loan, which substitution or
repurchase shall be accomplished in the manner and subject to the conditions
set forth in Section 2.03 (treating each Delay Delivery Mortgage Loan as a
Deleted Mortgage Loan for purposes of such Section 2.03); provided, however,
that if Countrywide fails to deliver a Mortgage File for any Delay Delivery
Mortgage Loan within the thirty (30) day period provided in the prior
sentence, Countrywide (on its own behalf and on behalf of Park Granada, Park
Monaco and Park Sienna) shall use its best reasonable efforts to effect a
substitution, rather than a repurchase of, such Deleted Mortgage Loan and
provided further that the cure period provided for in Section 2.02 or in
Section 2.03 shall not apply to the initial delivery of the Mortgage File for
such Delay Delivery Mortgage Loan, but rather Countrywide (on its own behalf
and on behalf of Park Granada, Park Monaco and Park Sienna) shall have five
(5) Business Days to cure such failure to deliver. At the end of such thirty
(30) day period the Trustee shall send a Delay Delivery Certification for the
Delay Delivery Mortgage Loans delivered during such thirty (30) day period in
accordance with the provisions of Section 2.02.

            (d) Neither the Depositor nor the Trust will acquire or hold any
Mortgage Loan that would violate the representations made by Countrywide set
forth in clause (49) of Schedule III-A hereto.

            SECTION 2.02. Acceptance by Trustee of the Mortgage Loans.

            (a) The Trustee acknowledges receipt of the documents identified
in the Initial Certification in the form annexed hereto as Exhibit F-1 and
declares that it holds and will hold such documents and the other documents
delivered to it constituting the Mortgage Files, and that it holds or will
hold such other assets as are included in the Trust Fund, in trust for the
exclusive use and benefit of all present and future Certificateholders. The
Trustee acknowledges that it will maintain possession of the Mortgage Notes in
the State of California, unless otherwise permitted by the Rating Agencies.

            The Trustee agrees to execute and deliver on the Closing Date to
the Depositor, the Master Servicer and Countrywide (on its own behalf and on
behalf of Park Granada, Park Monaco and


                                     II-4
<PAGE>


Park Sienna) an Initial Certification in the form annexed hereto as Exhibit
F-1. Based on its review and examination, and only as to the documents
identified in such Initial Certification, the Trustee acknowledges that such
documents appear regular on their face and relate to such Mortgage Loan. The
Trustee shall be under no duty or obligation to inspect, review or examine
said documents, instruments, certificates or other papers to determine that
the same are genuine, enforceable or appropriate for the represented purpose
or that they have actually been recorded in the real estate records or that
they are other than what they purport to be on their face.

            On or about the thirtieth (30th) day after the Closing Date, the
Trustee shall deliver to the Depositor, the Master Servicer and Countrywide
(on its own behalf and on behalf of Park Granada, Park Monaco and Park Sienna)
a Delay Delivery Certification with respect to the Mortgage Loans in the form
annexed hereto as Exhibit G-1, with any applicable exceptions noted thereon.

            Not later than 90 days after the Closing Date, the Trustee shall
deliver to the Depositor, the Master Servicer and Countrywide (on its own
behalf and on behalf of Park Granada, Park Monaco and Park Sienna) a Final
Certification with respect to the Mortgage Loans in the form annexed hereto as
Exhibit H-1, with any applicable exceptions noted thereon. If, in the course
of such review, the Trustee finds any document constituting a part of a
Mortgage File which does not meet the requirements of Section 2.01, the
Trustee shall list such as an exception in the Final Certification; provided,
however that the Trustee shall not make any determination as to whether (i)
any endorsement is sufficient to transfer all right, title and interest of the
party so endorsing, as noteholder or assignee thereof, in and to that Mortgage
Note or (ii) any assignment is in recordable form or is sufficient to effect
the assignment of and transfer to the assignee thereof under the mortgage to
which the assignment relates. Countrywide (on its own behalf and on behalf of
Park Granada, Park Monaco and Park Sienna) shall promptly correct or cure such
defect within 90 days from the date it was so notified of such defect and, if
Countrywide does not correct or cure such defect within such period,
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) shall either (a) substitute for the related Mortgage Loan a
Substitute Mortgage Loan, which substitution shall be accomplished in the
manner and subject to the conditions set forth in Section 2.03, or (b)
purchase such Mortgage Loan from the Trustee within 90 days from the date
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) was notified of such defect in writing at the Purchase Price of
such Mortgage Loan; provided, however, that in no event shall such
substitution or purchase occur more than 540 days from the Closing Date,
except that if the substitution or purchase of a Mortgage Loan pursuant to
this provision is required by reason of a delay in delivery of any documents
by the appropriate recording office, and there is a dispute between either the
Master Servicer or Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) and the Trustee over the location or
status of the recorded document, then such substitution or purchase shall
occur within 720 days from the Closing Date. The Trustee shall deliver written
notice to each Rating Agency within 270 days from the Closing Date indicating
each Mortgage Loan (a) which has not been returned by the appropriate
recording office or (b) as to which there is a dispute as to location or
status of such Mortgage Loan. Such notice shall be delivered every 90 days
thereafter until the related Mortgage Loan is returned to the Trustee. Any
such substitution pursuant to (a) above or purchase pursuant to (b) above
shall not be effected prior to the delivery to the Trustee of the Opinion of
Counsel required by Section 2.05 hereof, if any, and any substitution pursuant
to (a) above shall not be effected prior to the additional delivery to the
Trustee of a Request for Release substantially in the form of Exhibit N. No
substitution is permitted to be made in any calendar month after the
Determination Date for such month. The Purchase Price for any such Mortgage
Loan shall be deposited by Countrywide (on its own behalf and on behalf of
Park Granada, Park Monaco and Park Sienna) in the Certificate Account on or
prior to the Distribution Account Deposit Date for the Distribution Date in
the month following the month of repurchase and, upon receipt of such deposit
and certification with respect thereto in the form of Exhibit N hereto, the
Trustee shall release the related Mortgage File to Countrywide (on its own
behalf and on behalf of Park Granada, Park Monaco and Park


                                     II-5
<PAGE>


Sienna) and shall execute and deliver at Countrywide's (on its own behalf and
on behalf of Park Granada, Park Monaco and Park Sienna) request such
instruments of transfer or assignment prepared by Countrywide, in each case
without recourse, as shall be necessary to vest in Countrywide (on its own
behalf and on behalf of Park Granada, Park Monaco and Park Sienna), or its
designee, the Trustee's interest in any Mortgage Loan released pursuant
hereto. If pursuant to the foregoing provisions Countrywide (on its own behalf
and on behalf of Park Granada, Park Monaco and Park Sienna) repurchases an
Mortgage Loan that is a MERS Mortgage Loan, the Master Servicer shall either

            (c) Upon discovery by any of the parties hereto of a breach of a
representation or warranty with respect to a Mortgage Loan made pursuant to
Section 2.03(a) that materially and adversely affects the interests of the
Certificateholders in that Mortgage Loan, the party discovering such breach
shall give prompt notice thereof to the other parties. Each Seller hereby
covenants that within 90 days of the earlier of its discovery or its receipt
of written notice from any party of a breach of any representation or warranty
with respect to a Mortgage Loan sold by it pursuant to Section 2.03(a) which
materially and adversely affects the interests of the Certificateholders in

repurchasing a Mortgage Loan pursuant to this Section 2.03(c) shall promptly

described in this Section which are made to the best of a Seller's knowledge,
if it is discovered by either the Depositor, a Seller or the Trustee that the
substance of such representation and warranty is inaccurate and such
inaccuracy materially and adversely affects the value of the related Mortgage

Seller's lack of knowledge with respect to the substance of such
representation or warranty, such inaccuracy shall be deemed a breach of the
applicable representation or warranty. Any breach of a representation set

Mortgage Loan shall be deemed to materially and adversely affect the
Certificateholders.
