          THIS POOLING AND SERVICING AGREEMENT, dated as of January 1, 2007,
among CWALT, INC., a Delaware corporation, as depositor (the "Depositor"),
COUNTRYWIDE HOME LOANS, INC. ("Countrywide"), a New York corporation, as a
seller (a "Seller"), PARK GRANADA LLC ("Park Granada"), a Delaware limited
liability company, as a seller (a "Seller"), PARK MONACO INC. ("Park Monaco"),
a Delaware corporation, as a seller (a "Seller"), PARK SIENNA LLC ("Park
Sienna"), a Delaware limited liability company, as a seller (a "Seller")
COUNTRYWIDE HOME LOANS SERVICING LP, a Texas limited partnership, as master
servicer (the "Master Servicer"), and THE BANK OF NEW YORK, a banking
corporation organized under the laws of the State of New York, as trustee (the
"Trustee").

                                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 (other than
the Pre-Funding Account and the Capitalized Interest Account) 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 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 ES Trust shall hold the LTR-A-R Interest, the MR-A-R Interest,
all Master REMIC regular interests and shall issue the Certificates. Each
Certificate, other than the Class A-R Certificate, will represent ownership of
one or more of the Master REMIC regular interests held by the ES Trust. The
Class A-R Certificate will represent ownership of the LTR-A-R Interest and the
MR-A-R Interest, which are, respectively, the sole Classes of REMIC residual
interest in each of the Lower Tier REMIC and the Master REMIC.

          For federal income tax purposes the Trustee shall treat the ES Trust
as a Grantor Trust and shall treat each Holder of an ES Trust Certificate as
the owner of the individual, underlying assets represented by such ES Trust
Certificate. In addition, to the fullest extent possible, ownership of an ES
Trust Certificate shall be treated as direct ownership of the individual,
underlying assets represented by such ES Trust Certificate for federal income
tax reporting purposes.

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

     The following table sets forth characteristics of the ES Trust
Certificates, together with the minimum denominations and integral multiples
in excess thereof in which such Classes shall be issuable (except that one
Certificate of each Class of Certificates may be issued in a different amount
and, in addition, one Residual Certificate representing the Tax Matters Person
Certificate may be issued in a different amount):

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

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

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

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

                                     II-1
<PAGE>


               (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) except as provided below and for each Mortgage Loan that is not
     a MERS Mortgage Loan, the original recorded Mortgage or a copy of such
     Mortgage, with recording information, certified by Countrywide as being a
     true and complete copy of the 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

          (vi) in the case of a Cooperative Loan, the originals of the
     following documents or instruments:

               (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


                                     II-2
<PAGE>


          from the mortgagee to the Trustee with evidence of recording thereon
          (or in a form suitable for recordation).

          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


                                     II-3
<PAGE>


assignee thereof, affix the following language to each assignment of Mortgage:
"CWALT Series 2007-1T1, 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
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 (46) 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.


                                     II-4
<PAGE>


          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 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


                                     II-5
<PAGE>


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 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 (i) cause MERS to execute and deliver
an assignment of the Mortgage in recordable form to transfer the Mortgage from
MERS to Countrywide (on its own behalf and on behalf of Park Granada, Park
Monaco and Park Sienna) or its designee and shall cause such Mortgage to be
removed from registration on the MERS(R) System in accordance with MERS' rules
and regulations or (ii) cause MERS to designate on the MERS(R) System
Countrywide (on its own behalf and on behalf of Park Granada, Park Monaco and
Park Sienna) or its designee as the beneficial holder of such Mortgage Loan.

          (b) [Reserved].

          (c) The Trustee shall retain possession and custody of each Mortgage
File in accordance with and subject to the terms and conditions set forth
herein. The Master Servicer shall promptly deliver to the Trustee, upon the
execution or receipt thereof, the originals of such other documents or
instruments constituting the Mortgage File as come into the possession of the
Master Servicer from time to time.

          (d) It is understood and agreed that the respective obligations of
each Seller to substitute for or to purchase any Mortgage Loan sold to the
Depositor by it which does not meet the requirements of Section 2.01 above
shall constitute the sole remedy respecting such defect available to the
Trustee, the Depositor and any Certificateholder against that Seller.

          (e) [Reserved].

          (f) [Reserved].

          SECTION 2.03. Representations, Warranties and Covenants of the
                        Sellers and Master Servicer.

           (a) Countrywide hereby makes the representations and warranties set
forth in (i) Schedule II-A, Schedule II-B, Schedule II-C and Schedule II-D
hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date, (ii) Schedule III-A
hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date, or if so specified
therein, as of the Cut-off Date with respect to all of the Mortgage Loans, and
(iii) Schedule III-B hereto, and by this reference incorporated herein, to the
Depositor, the Master Servicer and the Trustee, as of the Closing Date, or if
so specified therein, as of the Cut-off Date with respect to the Mortgage
Loans that are Countrywide Mortgage Loans. Park Granada hereby makes the
representations and warranties set forth in (i) Schedule II-B hereto, and by
this reference incorporated herein, to the Depositor, the Master Servicer and
the Trustee, as of the Closing Date and (ii) Schedule III-C hereto, and by
this reference incorporated herein, to the Depositor, the Master Servicer and
the Trustee, as of the Closing Date, or if so specified therein, as of the
Cut-off Date with respect to the Mortgage Loans that are Park Granada Mortgage
Loans. Park Monaco hereby makes the representations and warranties set forth
in (i) Schedule II-C hereto, and by this reference incorporated herein, to the
Depositor, the Master Servicer and the Trustee, as of the Closing Date and
(ii) Schedule III-


                                     II-6
<PAGE>


D hereto, and by this reference incorporated herein, to the Depositor, the
Master Servicer and the Trustee, as of the Closing Date, or if so specified
therein, as of the Cut-off Date with respect to the Mortgage Loans that are
Park Monaco Mortgage Loans. Park Sienna hereby makes the representations and
warranties set forth in (i) Schedule II-D hereto, and by this reference
incorporated herein, to the Depositor, the Master Servicer and the Trustee, as
of the Closing Date and (ii) Schedule III-E hereto, and by this reference
incorporated herein, to the Depositor, the Master Servicer and the Trustee, as
of the Closing Date, or if so specified therein, as of the Cut-off Date with
respect to the Mortgage Loans that are Park Sienna Mortgage Loans.

          (b) The Master Servicer hereby makes the representations and
warranties set forth in Schedule IV hereto, and by this reference incorporated
herein, to the Depositor and the Trustee, as of the Closing Date.

          (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
that Mortgage Loan, it shall cure such breach in all material respects, and if
such breach is not so cured, shall, (i) if such 90-day period expires prior to
the second anniversary of the Closing Date, remove such Mortgage Loan (a
"Deleted Mortgage Loan") from the Trust Fund and substitute in its place a
Substitute Mortgage Loan, in the manner and subject to the conditions set
forth in this Section; or (ii) repurchase the affected Mortgage Loan or
Mortgage Loans from the Trustee at the Purchase Price in the manner set forth
below; provided, however, that any such substitution pursuant to (i) 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 such substitution
pursuant to (i) 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
and the Mortgage File for any such Substitute Mortgage Loan. The Seller
repurchasing a Mortgage Loan pursuant to this Section 2.03(c) shall promptly
reimburse the Master Servicer and the Trustee for any expenses reasonably
incurred by the Master Servicer or the Trustee in respect of enforcing the
remedies for such breach. With respect to the representations and warranties
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
Loan or the interests of the Certificateholders therein, notwithstanding that
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.

          With respect to any Substitute Mortgage Loan or Loans, sold to the
Depositor by a Seller, Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) shall deliver to the Trustee for the
benefit of the Certificateholders the Mortgage Note, the Mortgage, the related
assignment of the Mortgage, and such other documents and agreements as are
required by Section 2.01, with the Mortgage Note endorsed and the Mortgage
assigned as required by Section 2.01. No substitution is permitted to be made
in any calendar month after the Determination Date for such month. Scheduled
Payments due with respect to Substitute Mortgage Loans in the month of
substitution shall not be part of the Trust Fund and will be retained by the
related Seller on the next succeeding Distribution Date. For the month of
substitution, distributions to Certificateholders will include the monthly
payment due on any Deleted Mortgage Loan for such month and thereafter that
Seller shall be entitled to retain all amounts received in respect of such
Deleted Mortgage Loan. The Master Servicer shall amend the Mortgage Loan
Schedule for the benefit of the Certificateholders to reflect the removal of
such Deleted


                                     II-7
<PAGE>


Mortgage Loan and the substitution of the Substitute Mortgage Loan or Loans
and the Master Servicer shall deliver the amended Mortgage Loan Schedule to
the Trustee. Upon such substitution, the Substitute Mortgage Loan or Loans
shall be subject to the terms of this Agreement in all respects, and the
related Seller shall be deemed to have made with respect to such Substitute
Mortgage Loan or Loans, as of the date of substitution, the representations
and warranties made pursuant to Section 2.03(a) with respect to such Mortgage
Loan. Upon any such substitution and the deposit to the Certificate Account of
the amount required to be deposited therein in connection with such
substitution as described in the following paragraph, the Trustee shall
release the Mortgage File held for the benefit of the Certificateholders
relating to such Deleted Mortgage Loan to the related Seller and shall execute
and deliver at such Seller's direction such instruments of transfer or
assignment prepared by Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna), in each case without recourse, as shall
be necessary to vest title in that Seller, or its designee, the Trustee's
interest in any Deleted Mortgage Loan substituted for pursuant to this Section
2.03.

          For any month in which a Seller substitutes one or more Substitute
Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer
will determine the amount (if any) by which the aggregate principal balance of
all Substitute Mortgage Loans sold to the Depositor by that Seller as of the
date of substitution is less than the aggregate Stated Principal Balance of
all Deleted Mortgage Loans repurchased by that Seller (after application of
the scheduled principal portion of the monthly payments due in the month of
substitution). The amount of such shortage (the "Substitution Adjustment
Amount") plus an amount equal to the aggregate of any unreimbursed Advances
with respect to such Deleted Mortgage Loans shall be deposited in the
Certificate Account by Countrywide (on its own behalf and on behalf of Park
Granada, Park Monaco and Park Sienna) on or before the Distribution Account
Deposit Date for the Distribution Date in the month succeeding the calendar
month during which the related Mortgage Loan became required to be purchased
or replaced hereunder.

          In the event that a Seller shall have repurchased a Mortgage Loan,
the Purchase Price therefor shall be deposited in the Certificate Account
pursuant to Section 3.05 on or before the Distribution Account Deposit Date
for the Distribution Date in the month following the month during which that
Seller became obligated hereunder to repurchase or replace such Mortgage Loan
and upon such deposit of the Purchase Price, the delivery of the Opinion of
Counsel required by Section 2.05 and receipt of a Request for Release in the
form of Exhibit N hereto, the Trustee shall release the related Mortgage File
held for the benefit of the Certificateholders to such Person, and the Trustee
shall execute and deliver at such Person's direction such instruments of
transfer or assignment prepared by such Person, in each case without recourse,
as shall be necessary to transfer title from the Trustee. It is understood and
agreed that the obligation under this Agreement of any Person to cure,
repurchase or replace any Mortgage Loan as to which a breach has occurred and
is continuing shall constitute the sole remedy against such Persons respecting
such breach available to Certificateholders, the Depositor or the Trustee on
their behalf.

          The representations and warranties made pursuant to this Section
2.03 shall survive delivery of the respective Mortgage Files to the Trustee
for the benefit of the Certificateholders.

          SECTION 2.04. Representations and Warranties of the Depositor as to
                        the Mortgage Loans.

          The Depositor hereby represents and warrants to the Trustee with
respect to each Mortgage Loan as of the date hereof or such other date set
forth herein that as of the Closing Date, and following the transfer of the
Mortgage Loans to it by each Seller, the Depositor had good title to the
Mortgage Loans and the Mortgage Notes were subject to no offsets, defenses or
counterclaims.


                                     II-8
<PAGE>


          The Depositor hereby assigns, transfers and conveys to the Trustee
all of its rights with respect to the Mortgage Loans including, without
limitation, the representations and warranties of each Seller made pursuant to
Section 2.03(a)(ii) hereof, together with all rights of the Depositor to
require each Seller to cure any breach thereof or to repurchase or substitute
for any affected Mortgage Loan in accordance with this Agreement.

          It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the Mortgage Files to
the Trustee. Upon discovery by the Depositor or the Trustee of a breach of any
of the foregoing representations and warranties set forth in this Section 2.04
(referred to herein as a "breach"), which breach materially and adversely
affects the interest of the Certificateholders, the party discovering such
breach shall give prompt written notice to the others and to each Rating
Agency.

          SECTION 2.05. Delivery of Opinion of Counsel in Connection with
                        Substitutions.

          (a) Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to Section 2.02 or Section 2.03 shall be made more than
90 days after the Closing Date unless Countrywide delivers to the Trustee an
Opinion of Counsel, which Opinion of Counsel shall not be at the expense of
either the Trustee or the Trust Fund, addressed to the Trustee, to the effect
that such substitution will not (i) result in the imposition of the tax on
"prohibited transactions" on the Trust Fund or contributions after the Startup
Date, as defined in Sections 860F(a)(2) and 860G(d) of the Code, respectively,
or (ii) cause any REMIC created hereunder to fail to qualify as a REMIC at any
time that any Certificates are outstanding.

          (b) Upon discovery by the Depositor, a Seller, the Master Servicer,
or the Trustee that any Mortgage Loan does not constitute a "qualified
mortgage" within the meaning of Section 860G(a)(3) of the Code, the party
discovering such fact shall promptly (and in any event within five (5)
Business Days of discovery) give written notice thereof to the other parties.
In connection therewith, the Trustee shall require Countrywide (on its own
behalf and on behalf of Park Granada, Park Monaco and Park Sienna), at its
option, to either (i) substitute, if the conditions in Section 2.03(c) with
respect to substitutions are satisfied, a Substitute Mortgage Loan for the
affected Mortgage Loan, or (ii) repurchase the affected Mortgage Loan within
90 days of such discovery in the same manner as it would a Mortgage Loan for a
breach of representation or warranty made pursuant to Section 2.03. The
Trustee shall reconvey to Countrywide the Mortgage Loan to be released
pursuant hereto in the same manner, and on the same terms and conditions, as
it would a Mortgage Loan repurchased for breach of a representation or
warranty contained in Section 2.03.

          SECTION 2.06. Execution and Delivery of Certificates.

          The Trustee acknowledges the transfer and assignment to it of the
Trust Fund and, concurrently with such transfer and assignment, has executed
and delivered to or upon the order of the Depositor, the Certificates in
authorized denominations evidencing directly or indirectly the entire
ownership of the Trust Fund. The Trustee agrees to hold the Trust Fund and
exercise the rights referred to above for the benefit of all present and
future Holders of the Certificates and to perform the duties set forth in this
Agreement, to the end that the interests of the Holders of the Certificates
may be adequately and effectively protected.

          SECTION 2.07. REMIC Matters.

          The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests
created hereby. The "Startup Day" for purposes of the


                                     II-9
<PAGE>


REMIC Provisions shall be the Closing Date. The "tax matters person" with
respect to each REMIC hereunder shall be the Trustee and the Trustee shall
hold the Tax Matters Person Certificate. Each REMIC's fiscal year shall be the
calendar year.

          SECTION 2.08. Covenants of the Master Servicer.

          The Master Servicer hereby covenants to the Depositor and the
Trustee as follows:

          (a) the Master Servicer shall comply in the performance of its
obligations under this Agreement with all reasonable rules and requirements of
the insurer under each Required Insurance Policy; and

          (b) no written information, certificate of an officer, statement
furnished in writing or written report delivered to the Depositor, any
affiliate of the Depositor or the Trustee and prepared by the Master Servicer
pursuant to this Agreement will contain any untrue statement of a material
fact or omit to state a material fact necessary to make such information,
certificate, statement or report not misleading.

                                  ARTICLE III

                         ADMINISTRATION AND SERVICING
                               OF MORTGAGE LOANS

          SECTION 3.01. Master Servicer to Service Mortgage Loans.

          For and on behalf of the Certificateholders, the Master Servicer
shall service and administer the Mortgage Loans in accordance with the terms
of this Agreement and customary and usual standards of practice of prudent
mortgage loan servicers. In connection with such servicing and administration,
the Master Servicer shall have full power and authority, acting alone and/or
through Subservicers as provided in Section 3.02 hereof, subject to the terms
hereof (i) to execute and deliver, on behalf of the Certificateholders and the
Trustee, customary consents or waivers and other instruments and documents,
(ii) to consent to transfers of any Mortgaged Property and assumptions of the
Mortgage Notes and related Mortgages (but only in the manner provided in this
Agreement), (iii) to collect any Insurance Proceeds and other Liquidation
Proceeds (which, for the purpose of this Section, includes any Subsequent
Recoveries), and (iv) to effectuate foreclosure or other conversion of the
ownership of the Mortgaged Property securing any Mortgage Loan; provided that
the Master Servicer shall not take any action that is inconsistent with or
prejudices the interests of the Trust Fund or the Certificateholders in any
Mortgage Loan or the rights and interests of the Depositor, the Trustee and
the Certificateholders under this Agreement. The Master Servicer shall
represent and protect the interests of the Trust Fund in the same manner as it
protects its own interests in mortgage loans in its own portfolio in any
claim, proceeding or litigation regarding a Mortgage Loan, and shall not make
or permit any modification, waiver or amendment of any Mortgage Loan which
would cause any REMIC created hereunder to fail to qualify as a REMIC or
result in the imposition of any tax under Section 860F(a) or Section 860G(d)
of the Code. Without limiting the generality of the foregoing, the Master
Servicer, in its own name or in the name of the Depositor and the Trustee, is
hereby authorized and empowered by the Depositor and the Trustee, when the
Master Servicer believes it appropriate in its reasonable judgment, to execute
and deliver, on behalf of the Trustee, the Depositor, the Certificateholders
or any of them, any and all instruments of satisfaction or cancellation, or of
partial or full release or discharge and all other comparable instruments,
with respect to the Mortgage Loans, and with respect to the Mortgaged
Properties held for the benefit of the Certificateholders. The Master Servicer
shall prepare and deliver to the Depositor and/or the Trustee such documents
requiring execution and delivery by either or both of them as are necessary or
appropriate to enable the Master Servicer to service and administer the
Mortgage Loans to the extent that the Master Servicer is not permitted to
execute and deliver such documents pursuant to the preceding sentence. Upon
receipt of such documents, the Depositor and/or the Trustee shall execute such
documents and deliver them to the Master Servicer. The Master Servicer further
is authorized and empowered by the Trustee, on behalf of the
Certificateholders and the Trustee, in its own name or in the name of the
Subservicer, when the Master Servicer or the Subservicer, as the case may be,
believes it appropriate in its best judgment to register any Mortgage Loan on
the MERS(R) System, or cause the removal from the registration of any Mortgage
Loan on the MERS(R) System, to execute and deliver, on behalf of the Trustee
and the Certificateholders or any of them, any and all instruments of
assignment and other comparable instruments with respect to such assignment or
re-recording of a Mortgage in the name of MERS, solely as nominee for the
Trustee and its successors and assigns.

          In accordance with the standards of the preceding paragraph, the
Master Servicer shall advance or cause to be advanced funds as necessary for
the purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.06, and further
as provided in Section 3.08. The costs incurred by the Master Servicer, if
any, in effecting the timely payments of taxes and assessments on the
Mortgaged Properties and related insurance premiums shall not, for the purpose
of


                                    III-1
<PAGE>


calculating monthly distributions to the Certificateholders, be added to the
Stated Principal Balances of the related Mortgage Loans, notwithstanding that
the terms of such Mortgage Loans so permit.

          SECTION 3.02. Subservicing; Enforcement of the Obligations of
                        Subservicers.

          (a) The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a Subservicer pursuant to a subservicing agreement; provided,
however, that such subservicing arrangement and the terms of the related
subservicing agreement must provide for the servicing of such Mortgage Loans
in a manner consistent with the servicing arrangements contemplated hereunder.
Unless the context otherwise requires, references in this Agreement to actions
taken or to be taken by the Master Servicer in servicing the Mortgage Loans
include actions taken or to be taken by a Subservicer on behalf of the Master
Servicer. Notwithstanding the provisions of any subservicing agreement, any of
the provisions of this Agreement relating to agreements or arrangements
between the Master Servicer and a Subservicer or reference to actions taken
through a Subservicer or otherwise, the Master Servicer shall remain obligated
and liable to the Depositor, the Trustee and the Certificateholders for the
servicing and administration of the Mortgage Loans in accordance with the
provisions of this Agreement without diminution of such obligation or
liability by virtue of such subservicing agreements or arrangements or by
virtue of indemnification from the Subservicer and to the same extent and
under the same terms and conditions as if the Master Servicer alone were
servicing and administering the Mortgage Loans. All actions of each
Subservicer performed pursuant to the related subservicing agreement shall be
performed as an agent of the Master Servicer with the same force and effect as
if performed directly by the Master Servicer.

          (b) For purposes of this Agreement, the Master Servicer shall be
deemed to have received any collections, recoveries or payments with respect
to the Mortgage Loans that are received by a Subservicer regardless of whether
such payments are remitted by the Subservicer to the Master Servicer.

          SECTION 3.03. Rights of the Depositor and the Trustee in Respect of
                        the Master Servicer.

          The Depositor may, but is not obligated to, enforce the obligations
of the Master Servicer hereunder and may, but is not obligated to, perform, or
cause a designee to perform, any defaulted obligation of the Master Servicer
hereunder and in connection with any such defaulted obligation to exercise the
related rights of the Master Servicer hereunder; provided that the Master
Servicer shall not be relieved of any of its obligations hereunder by virtue
of such performance by the Depositor or its designee. Neither the Trustee nor
the Depositor shall have any responsibility or liability for any action or
failure to act by the Master Servicer nor shall the Trustee or the Depositor
be obligated to supervise the performance of the Master Servicer hereunder or
otherwise.

          SECTION 3.04. Trustee to Act as Master Servicer.

          In the event that the Master Servicer shall for any reason no longer
be the Master Servicer hereunder (including by reason of an Event of Default
or termination by the Depositor), the Trustee or its successor shall thereupon
assume all of the rights and obligations of the Master Servicer hereunder
arising thereafter (except that the Trustee shall not be (i) liable for losses
of the Master Servicer pursuant to Section 3.09 hereof or any acts or
omissions of the predecessor Master Servicer hereunder), (ii) obligated to
make Advances if it is prohibited from doing so by applicable law, (iii)
obligated to effectuate repurchases or substitutions of Mortgage Loans
hereunder including, but not limited to, repurchases or substitutions of
Mortgage Loans pursuant to Section 2.02 or 2.03 hereof, (iv) responsible for
expenses of the Master Servicer pursuant to Section 2.03 or (v) deemed to have
made any representations and warranties of the Master Servicer hereunder). Any
such assumption shall be subject to Section 7.02


                                    III-2
<PAGE>


hereof. If the Master Servicer shall for any reason no longer be the Master
Servicer (including by reason of any Event of Default or termination by the
Depositor), the Trustee or its successor shall succeed to any rights and
obligations of the Master Servicer under each subservicing agreement.

           The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party all documents
and records relating to each subservicing agreement or substitute subservicing
agreement and the Mortgage Loans then being serviced thereunder and an
accounting of amounts collected or held by it and otherwise use its best
efforts to effect the orderly and efficient transfer of the substitute
subservicing agreement to the assuming party.

          SECTION 3.05. Collection of Mortgage Loan Payments; Certificate
                        Account; Distribution Account; the Supplemental
                        Interest Trust, the Corridor Contract Reserve Fund.

          (a) The Master Servicer shall make reasonable efforts in accordance
with the customary and usual standards of practice of prudent mortgage
servicers to collect all payments called for under the terms and provisions of
the Mortgage Loans to the extent such procedures shall be consistent with this
Agreement and the terms and provisions of any related Required Insurance
Policy. Consistent with the foregoing, the Master Servicer may in its
discretion (i) waive any late payment charge or any Prepayment Charge or
penalty interest in connection with the prepayment of a Mortgage Loan and (ii)
extend the due dates for payments due on a Mortgage Note for a period not
greater than 180 days; provided, however, that the Master Servicer cannot
extend the maturity of any such Mortgage Loan past the date on which the final
payment is due on the latest maturing Mortgage Loan as of the Cut-off Date. In
the event of any such arrangement, the Master Servicer shall make Advances on
the related Mortgage Loan in accordance with the provisions of Section 4.01
during the scheduled period in accordance with the amortization schedule of
such Mortgage Loan without modification thereof by reason of such
arrangements. The Master Servicer shall not be required to institute or join
in litigation with respect to collection of any payment (whether under a
Mortgage, Mortgage Note or otherwise or against any public or governmental
authority with respect to a taking or condemnation) if it reasonably believes
that enforcing the provision of the Mortgage or other instrument pursuant to
which such payment is required is prohibited by applicable law.

          (b) The Master Servicer shall establish and maintain a Certificate
Account into which the Master Servicer shall deposit or cause to be deposited
no later than two Business Days after receipt (or, if the current long-term
credit rating of Countrywide is reduced below "A-" by S&P or Fitch, or "A3" by
Moody's, the Master Servicer shall deposit or cause to be deposited on a daily
basis within one Business Day of receipt), except as otherwise specifically
provided herein, the following payments and collections remitted by
Subservicers or received by it in respect of Mortgage Loans subsequent to the
Cut-off Date (other than in respect of principal and interest due on the
Mortgage Loans on or before the Cut-off Date) and the following amounts
required to be deposited hereunder:

          (i) all payments on account of principal on the Mortgage Loans,
     including Principal Prepayments;

          (ii) all payments on account of interest on the Mortgage Loans, net
     of the Master Servicing Fee, Prepayment Interest Excess and any
     lender-paid mortgage insurance premiums;

          (iii) [Reserved];


                                    III-3
<PAGE>


          (iv) all Insurance Proceeds, Subsequent Recoveries and Liquidation
     Proceeds, other than proceeds to be applied to the restoration or repair
     of the Mortgaged Property or released to the Mortgagor in accordance with
     the Master Servicer's normal servicing procedures;

           (v) any amount required to be deposited by the Master Servicer or
     the Depositor pursuant to Section 3.05(e) in connection with any losses
     on Permitted Investments for which it is responsible;

          (vi) any amounts required to be deposited by the Master Servicer
     pursuant to Section 3.09(c) and in respect of net monthly rental income
     from REO Property pursuant to Section 3.11 hereof;

          (vii) all Substitution Adjustment Amounts;

          (viii) all Advances made by the Master Servicer pursuant to Section
     4.01; and

          (ix) any other amounts required to be deposited hereunder.

          In addition, with respect to any Mortgage Loan that is subject to a
buydown agreement, on each Due Date for such Mortgage Loan, in addition to the
monthly payment remitted by the Mortgagor, the Master Servicer shall cause
funds to be deposited into the Certificate Account in an amount required to
cause an amount of interest to be paid with respect to such Mortgage Loan
equal to the amount of interest that has accrued on such Mortgage Loan from
the preceding Due Date at the Mortgage Rate net of the Master Servicing Fee.

          The foregoing requirements for remittance by the Master Servicer
shall be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of Prepayment Charges,
late payment charges or assumption fees, if collected, need not be remitted by
the Master Servicer. In the event that the Master Servicer shall remit any
