                                WITNESSETH THAT

      In consideration of the mutual agreements contained in this Agreement,
the parties to this Agreement 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. The Trust Fund (excluding the
Carryover Reserve Fund) for federal income tax purposes will consist of three
REMICs (the "Swap-IO REMIC," the " Strip REMIC" and the "Master REMIC").
Each Certificate, other than the Class A-R Certificate, will represent
ownership of one or more regular interests in the Master REMIC for purposes
of the REMIC Provisions. The Class A-R Certificate represents ownership of
the sole class of residual interest in the Swap-IO REMIC,   Strip REMIC and
the Master REMIC.   The Master REMIC will hold as assets the several classes
of uncertificated Strip REMIC Interests (other than the STR-A-R Interest).
Each Strip REMIC Interest (other than the STR-A-R Interest) is hereby
designated as a regular interest in the Strip REMIC.   The Strip REMIC will
hold as assets the several classes of uncertificated Swap-IO REMIC Interests
(other than the SWR-A-R Interest). Each Swap-IO REMIC Interest (other than
the SWR-A-R Interest) is hereby designated as a regular interest in the
Swap-IO REMIC.   The Swap-IO REMIC will hold as assets all property of the
Trust Fund (excluding the Carryover Reserve Fund).   The latest possible
maturity date of all REMIC regular interests created in this Agreement shall
be the Latest Possible Maturity Date.

      The Swap Trust, Swap Contract and Swap Account will not constitute any

(1)    This Strip REMIC Interest has a principal balance that is initially
equal to 100% of its corresponding Certificate Class issued by the Master
REMIC.   Principal payments, both scheduled and prepaid, Realized Losses and
Subsequent Recoveries attributable to the SWAP-IO REMIC Interests held by the
Strip REMIC will be allocated to this class to maintain its size relative to
its corresponding Certificate Class.

(2)    On each Distribution Date, the pass through rate will equal the "Strip
REMIC Cap."   The Strip REMIC Cap will equal the weighted average of the pass
through rates of the Swap-IO REMIC Interests (other than the Class SWR-P and
Class SWR-A-R Interests) treating each "B" Interest the cardinal number of
which (for example, SW-1B, SW-2B, SW-3B, etc.,) is not less than the ordinal
number of the Distribution Date (first Distribution Date, second Distribution
Date, third Distribution Date, etc., ) as capped at a rate equal to the
product of (i) 2 and (ii) LIBOR.

(3)    This Strip REMIC Interest pays no interest.

(4)    This Strip REMIC Interest has a principal balance that is initially
equal to 100% of the Overcollateralization Amount.   Principal payments, both
scheduled and prepaid, Realized Losses and Subsequent Recoveries attributable
to the Swap-IO REMIC Interests held by the Strip


                                       5
<PAGE>


REMIC will be allocated to this class to maintain its size relative to the
Overcollateralization Amount.

(5)    For each Distribution Date, the STR-C-Swap-IO Interest is entitled to
receive from each Swap REMIC "B" Interest the cardinal number of which (for
example, SW-1B, SW-2B, SW-3B, etc.,) is not less than the ordinal number of
the Distribution Date (first Distribution Date, second Distribution Date,
third Distribution Date, etc.) the interest accruing on such interest in
excess of a per annum rate equal to the product of (i) 2 and (ii) LIBOR.

(6)    The STR-P Interest is entitled to all amounts payable with respect to
the SWR-P Interest.   It pays no interest.

(7)    The STR-A-R Interest is the sole class of residual interest in the
Strip REMIC.   It has no principal balance and pays no principal or interest.

      On each Distribution Date, the Interest Funds and the Principal
Distribution Amount payable with respect to the Swap-IO Interests shall be
payable with respect to the Strip REMIC Interests in the following manner:

      (1)    Interest.   Interest is to be distributed with respect to each
Strip REMIC Interest at the rate, or according to the formulas, described
above.

      (2)    Principal.   Principal Distribution Amounts shall be allocated
among the Strip REMIC   Interests as described above.

      (3) Prepayment Penalties.   All Prepayment Charges are allocated to the
STR-P Interest.

(1)    The Certificates will accrue interest at the related Pass-Through Rates
identified in this Agreement.   For federal income tax purposes, including the
computation of the Class C Distributable Amount and entitlement to Net Rate
Carryover the pass-through rate in respect of each Class 1 Certificate, Class
2 Certificate and Class M Certificate will be subject to a cap equal to the
Strip REMIC Cap rather than its applicable Net Rate Cap.

(2)    For federal income tax purposes, the Class C Certificates will be
treated as having a Certificate Principal Balance equal to the
Overcollateralized Amount.

(3)    For each Interest Accrual Period the Class C Certificates are entitled
to an amount (the "Class C Distributable Amount") equal to the sum of (a) the
interest payable on the STR-C-Swap-IO Interest, (b) the interest payable on
the STR-C-OC Interest and (c) a specified portion of the interest payable on
the Strip REMIC Regular Interests (other than the STR-$100, STR-C-OC,
STR-C-Swap-IO and STR-X Interests) equal to the excess of the Pool Tax Cap
over the weighted average interest rate of the Strip REMIC   Regular Interests
(other than the STR-$100, STR-C and STR-P Interests) with each such Class
subject to a cap and a floor equal to the Pass-Through Rate of the
Corresponding Master REMIC Class.   The Pass-Through Rate of the Class C
Certificates shall be a rate sufficient to entitle it to an amount equal to
all interest accrued on the Mortgage Loans less the interest accrued on the
other interests issued by the Master REMIC.   The Class C Distributable Amount
for any Distribution Date is payable from current interest on the Mortgage
Loans and any related Overcollateralization Reduction Amount for that
Distribution Date.

(4)    For each Distribution Date the Class P Certificates are entitled to all
Prepayment Charges distributed with respect to the STR-P Interest.

(5)    The Class A-R Certificates represent the sole class of residual
interest in each REMIC created hereunder.   The Class A-R Certificates are not
entitled to distributions of interest.

      The foregoing REMIC structure is intended to cause all of the cash from
the Mortgage Loans to flow through to the Master REMIC as cash flow on REMIC
regular interests, without creating any shortfall--actual or potential (other
than for credit losses)-- to any REMIC regular interest. It is not intended
that the Class A-R Certificates be entitled to any cash flows pursuant to
this Agreement except as provided in Section 4.02(b) hereunder.

                         CONVEYANCE OF MORTGAGE LOANS;
                        REPRESENTATIONS AND WARRANTIES

      SECTION 2.01.      Conveyance of Mortgage Loans.

       (a)    Each Seller, concurrently with the execution and delivery of this
Agreement, 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
applicable 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 payments of principal and interest due and
payable on such Mortgage Loans on or before the Cut-off Date.   On or prior to
the Closing Date, Countrywide shall deliver to the Depositor or, at the
Depositor's direction, to the Trustee or other designee of the Depositor, the
Mortgage File for each Mortgage Loan listed in the Mortgage Loan Schedule
(except that, in the case of the Delay Delivery Mortgage Loans (which may
include Countrywide Mortgage Loans, Park 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 applicable
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 in this Agreement 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


                                      48
<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, (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 a copy of
            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;


                                      49
<PAGE>


                    (E) The executed UCC-1 financing statement with evidence
                 of recording thereon which have been filed in all places
                 required to perfect the applicable 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).

      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, or (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 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 assignments, 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


                                      50
<PAGE>


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 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, Inc., Series
2006-OC7, 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.

      Notwithstanding anything to the contrary in this Agreement, within
thirty (30) days after the Closing Date with respect to the Mortgage Loans,
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


                                      51
<PAGE>


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 (an
"Initial Certification") 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 Park Sienna) an Initial Certification
in the form annexed to this Agreement 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 the Mortgage Loans.   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 (a "Delay Delivery Certification"),
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 (a "Final Certification"), 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 that 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


                                      52
<PAGE>


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) that 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, 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 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 a 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.

or instruments constituting the Mortgage File as come into the possession of

      (e)    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.

                        Sellers and Master Servicer.

      (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, the NIM Insurer and
the Swap Counterparty.   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) that 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, 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.   Any breach of a representation set forth in clauses (45) through
(64) of Schedule III-A with respect to a Mortgage Loan in Loan Group 1 shall
be deemed to materially and adversely affect the Certificateholders.

      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 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


                                      55
<PAGE>


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 of this Agreement or such other
date set forth in this Agreement


                                      56
<PAGE>


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.

      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), together with all rights of the Depositor to require a
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 and the NIM Insurer.

      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 under this Agreement 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
and the NIM Insurer.   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 to this Section 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


                                       57
<PAGE>


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 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, subject
to the terms of this Agreement (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 3.01 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
under this Agreement 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.


                                       59
<PAGE>


      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 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 under this Agreement; provided, however, that the NIM Insurer
shall have consented to such subservicing agreements (which consent shall not
be unreasonably withheld).   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, the NIM Insurer and the
                        Trustee in Respect of the Master Servicer.

      The Depositor may, but is not obligated to, enforce the obligations of
the Master Servicer under this Agreement and may, but is not obligated to,
perform, or cause a designee to perform, any defaulted obligation of the
Master Servicer under this Agreement and in connection with any such
defaulted obligation to exercise the related rights of the Master Servicer
under this Agreement; provided that the Master Servicer shall not be relieved
of any of its obligations under this Agreement by virtue of such performance
by the Depositor or its designee.   None of the Trustee, the NIM Insurer or
the Depositor shall have any responsibility or liability for any action


                                      60
<PAGE>


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
under this Agreement 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 under this Agreement (including by reason of an Event of
Default or termination by the Depositor), the Trustee or its successor shall
then assume all of the rights and obligations of the Master Servicer under
this Agreement arising thereafter (except that the Trustee shall not be
(i) liable for losses of the Master Servicer pursuant to Section 3.09 or any
acts or omissions of the predecessor Master Servicer under this Agreement),
(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 under this Agreement including, but not limited to,
repurchases or substitutions of Mortgage Loans pursuant to Section 2.02 or
2.03, (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 under this Agreement).   Any such assumption shall be
subject to Section 7.02.   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; Carryover Reserve
                         Fund; Principal 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, subject to Section 3.20, 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.   In addition, the NIM Insurer's prior written
consent shall be required for any waiver of Prepayment Charges or for the
extension of the due dates for payments due on a Mortgage Note, if the
aggregate number of outstanding Mortgage Loans that


                                      61
<PAGE>


have been granted such waivers or extensions exceeds 5% of the aggregate
number of Mortgage Loans.   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 "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 in this Agreement, 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 under this Agreement:

            (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 related Master Servicing Fee, Prepayment Interest Excess and
      any lender paid mortgage insurance premiums;

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

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

            (v)    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;

            (vi)   all Substitution Adjustment Amounts;

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

             (viii) all payments on account of Prepayment Charges on the Mortgage
      Loans; and

            (ix)   any other amounts required to be deposited under this
      Agreement.

      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


                                      62
<PAGE>


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
related 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 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 amount not
required to be remitted, it may at any time withdraw or direct the
institution maintaining the Certificate Account to withdraw such amount from
the Certificate Account, any provision in this Agreement to the contrary
notwithstanding.   Such withdrawal or direction may be accomplished by
delivering written notice thereof to the Trustee or such other institution
maintaining the Certificate Account which describes the amounts deposited in
error in the Certificate Account.   The Master Servicer shall maintain
adequate records with respect to all withdrawals made pursuant to this
Section.   All funds deposited in the Certificate Account shall be held in
trust for the Certificateholders until withdrawn in accordance with
Section 3.08.

      (c)    The Trustee shall establish and maintain, on behalf of the
Certificateholders, a Principal Reserve Fund in the name of the Trustee.   On
the Closing Date, the Depositor shall deposit into the Principal Reserve Fund
$100.   Funds on deposit in the Principal Reserve Fund shall not be invested.
The Principal Reserve Fund shall be treated as an "outside reserve fund"
under applicable Treasury regulations and shall not be part of any REMIC
created under this Agreement.   Amounts on deposit in the Principal Reserve
Fund shall not be invested.

      (d)    The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Distribution Account.   The Trustee shall, promptly
upon receipt, deposit in the Distribution Account and retain in the
Distribution Account the following:

            (i)    the aggregate amount remitted by the Master Servicer to the
      Trustee pursuant to Section 3.08(a)(ix);

             (ii)   any amount 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; and

            (iii) any other amounts deposited hereunder which are required to
      be deposited in the Distribution Account.

      In the event that the Master Servicer shall remit any amount not
required to be remitted, it may at any time direct the Trustee to withdraw
such amount from the Distribution Account, any provision in this Agreement to
the contrary notwithstanding.   Such direction may be accomplished by
delivering an Officer's Certificate to the Trustee which describes the
amounts deposited in error in the Distribution Account.   All funds deposited
in the Distribution Account shall be held by the Trustee in trust for the
Certificateholders until disbursed in accordance with this Agreement or
withdrawn in accordance with Section 3.08.   In no event shall the Trustee
incur liability for withdrawals from the Distribution Account at the
direction of the Master Servicer.


                                      63
<PAGE>


      (e)    Each institution at which the Certificate Account or the
Distribution Account is maintained shall invest the funds therein as directed
in writing by the Master Servicer in Permitted Investments, which shall
mature not later than (i) in the case of the Certificate Account, the second
Business Day next preceding the related Distribution Account Deposit Date
(except that if such Permitted Investment is an obligation of the institution
that maintains such account, then such Permitted Investment shall mature not
later than the Business Day next preceding such Distribution Account Deposit
Date) and (ii) in the case of the Distribution Account, the Business Day next
preceding the Distribution Date (except that if such Permitted Investment is
an obligation of the institution that maintains such fund or account, then
such Permitted Investment shall mature not later than such Distribution Date)
and, in each case, shall not be sold or disposed of prior to its maturity.
All such Permitted Investments shall be made in the name of the Trustee, for
the benefit of the Certificateholders.   All income and gain net of any losses
realized from any such investment of funds on deposit in the Certificate
Account, or the Distribution Account shall be for the benefit of the Master
Servicer as servicing compensation and shall be remitted to it monthly as
provided in this Agreement.   The amount of any realized losses in the
Certificate Account or the Distribution Account incurred in any such account
in respect of any such investments shall promptly be deposited by the Master
Servicer in the Certificate Account or paid to the Trustee for deposit into
the Distribution Account, as applicable.   The Trustee in its fiduciary
capacity shall not be liable for the amount of any loss incurred in respect
of any investment or lack of investment of funds held in the Certificate
Account or the Distribution Account and made in accordance with this Section
3.05.

      (f)    The Master Servicer shall give notice to the Trustee, each
Seller, each Rating Agency and the Depositor of any proposed change of the
location of the Certificate Account prior to any change thereof.   The Trustee
shall give notice to the Master Servicer, each Seller, each Rating Agency and
the Depositor of any proposed change of the location of the Distribution
Account or the Carryover Reserve Fund prior to any change thereof.

      (g)    On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of the Holders of the Offered
Certificates, the Carryover Reserve Fund and shall deposit $1,000 therein
upon receipt from or on behalf of the Depositor of such amount.   The
Carryover Reserve Fund shall be an Eligible Account, and funds on deposit
therein shall be held separate and apart from, and shall not be commingled
with, any other moneys, including without limitation, other moneys held by
the Trustee pursuant to this Agreement.

      Funds in the Carryover Reserve Fund may be invested in Permitted
Investments at the direction of the Majority of the Holders of the Class C
Certificates, which Permitted Investments shall mature not later than the
Business Day immediately preceding the first Distribution Date that follows
the date of such investment (except that if such Permitted Investment is an
obligation of the institution that maintains the Carryover Reserve Fund, then
such Permitted Investment shall mature not later than such Distribution Date)
and shall not be sold or disposed of prior to maturity.   All such Permitted
Investments shall be made in the name of the Trustee, for the benefit of the
Holders of the Class C Certificates. In the absence of such written
direction, all funds in the Carryover Reserve Fund shall be invested by the
Trustee in The Bank of New York cash reserves.   Any net investment earnings
on such amounts shall be retained therein until withdrawn as provided in
Section 3.08.   Any losses incurred in the Carryover Reserve Fund in respect
of any such investments shall be charged against amounts on deposit in the
Carryover Reserve Fund (or such investments) immediately as realized.   The
Trustee shall not be liable for


                                       64
<PAGE>


the amount of any loss incurred in respect of any investment or lack of
investment of funds held in the Carryover Reserve Fund and made in accordance
with this Section 3.05.   The Carryover Reserve Fund will not constitute an
asset of any REMIC created hereunder.   The Class C Certificates shall
evidence ownership of the Carryover Reserve Fund for federal tax purposes.

      SECTION 3.06.      Collection of Taxes, Assessments and Similar Items;
                        Escrow Accounts.

       (a)    To the extent required by the related Mortgage Note and not
violative of current law, the Master Servicer shall establish and maintain
one or more accounts (each, an "Escrow Account") and deposit and retain
therein all collections from the Mortgagors (or advances by the Master
Servicer) for the payment of taxes, assessments, hazard insurance premiums or
comparable items for the account of the Mortgagors.   Nothing in this
Agreement shall require the Master Servicer to compel a Mortgagor to
establish an Escrow Account in violation of applicable law.

      (b)    Withdrawals of amounts so collected from the Escrow Accounts may
be made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to
reimburse the Master Servicer out of related collections for any payments
made pursuant to Sections 3.01 (with respect to taxes and assessments and
insurance premiums) and 3.09 (with respect to hazard insurance), to refund to
any Mortgagors any sums determined to be overages, to pay interest, if
required by law or the terms of the related Mortgage or Mortgage Note, to
Mortgagors on balances in the Escrow Account or to clear and terminate the
Escrow Account at the termination of this Agreement in accordance with
Section 9.01.   The Escrow Accounts shall not be a part of the Trust Fund.

      (c)    The Master Servicer shall advance any payments referred to in
Section 3.06(a) that are not timely paid by the Mortgagors on the date when
the tax, premium or other cost for which such payment is intended is due, but
the Master Servicer shall be required so to advance only to the extent that
such advances, in the good faith judgment of the Master Servicer, will be
recoverable by the Master Servicer out of Insurance Proceeds, Liquidation
Proceeds or otherwise.

      SECTION 3.07.      Access to Certain Documentation and Information
                        Regarding the Mortgage Loans.

      The Master Servicer shall afford each Seller, the Depositor, the NIM
Insurer and the Trustee reasonable access to all records and documentation
regarding the Mortgage Loans and all accounts, insurance information and
other matters relating to this Agreement, such access being afforded without
charge, but only upon reasonable request and during normal business hours at
the office designated by the Master Servicer.

      Upon reasonable advance notice in writing, the Master Servicer will
provide to each Certificateholder and/or Certificate Owner which is a savings
and loan association, bank or insurance company certain reports and
reasonable access to information and documentation regarding the Mortgage
Loans sufficient to permit such Certificateholder and/or Certificate Owner to
comply with applicable regulations of the OTS or other regulatory authorities
with respect to investment in the Certificates; provided that the Master
Servicer shall be entitled to be


                                      65
<PAGE>


reimbursed by each such Certificateholder and/or Certificate Owner for actual
expenses incurred by the Master Servicer in providing such reports and
access.   Upon request, the Master Servicer shall furnish to the Trustee and
the NIM Insurer its most recent publicly available financial statements and
any other information relating to its capacity to perform its obligations
under this Agreement reasonably requested by the NIM Insurer.

      SECTION 3.08.      Permitted Withdrawals from the Certificate Account,
                        the Distribution Account, the Carryover Reserve Fund
                        and the Principal Reserve Fund.

      (a)    The Master Servicer may from time to time make withdrawals from
the Certificate Account for the following purposes:

            (i)    to pay to the Master Servicer (to the extent not previously
      retained by the Master Servicer) the servicing compensation to which it
      is entitled pursuant to Section 3.14 and to pay to the Master Servicer,
      as additional servicing compensation, earnings on or investment income
      with respect to funds in or credited to the Certificate Account;

            (ii)   to reimburse each of the Master Servicer and the Trustee
      for unreimbursed Advances made by it, such right of reimbursement
      pursuant to this subclause (ii) being limited to amounts received on
      the Mortgage Loan(s) in respect of which any such Advance was made;

            (iii) to reimburse each of the Master Servicer and the Trustee
      for any Nonrecoverable Advance previously made by it;

            (iv)   to reimburse the Master Servicer for Insured Expenses from
      the related Insurance Proceeds;

            (v)    to reimburse the Master Servicer for (a) unreimbursed
      Servicing Advances, the Master Servicer's right to reimbursement
      pursuant to this clause (a) with respect to any Mortgage Loan being
      limited to amounts received on such Mortgage Loan(s) that represent
      late recoveries of the payments for which such advances were made
      pursuant to Section 3.01 or Section 3.06 and (b) for unpaid Master
      Servicing Fees as provided in Section 3.11;

            (vi)   to pay to the purchaser, with respect to each Mortgage Loan
      or property acquired in respect thereof that has been purchased
      pursuant to Section 2.02, 2.03 or 3.11, all amounts received on such
      Mortgage Loan after the date of such purchase;

            (vii) to reimburse the Sellers, the Master Servicer, the NIM
      Insurer or the Depositor for expenses incurred by any of them and
      reimbursable pursuant to Section 6.03;

            (viii) to withdraw any amount deposited in the Certificate Account
      and not required to be deposited in the Certificate Account;


                                      66
<PAGE>


             (ix)   on or prior to the Distribution Account Deposit Date, to
      withdraw an amount equal to the related Interest Remittance Amount,
      Principal Remittance Amount, Prepayment Charge Amount collected and the
      Trustee Fee for such Distribution Date and remit such amount to the
      Trustee for deposit in the Distribution Account;   and

            (x)    to clear and terminate the Certificate Account upon
      termination of this Agreement pursuant to Section 9.01.

      The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Certificate Account pursuant to such subclauses (i),
(ii), (iv), (v) and (vi).   Prior to making any withdrawal from the
Certificate Account pursuant to subclause (iii), the Master Servicer shall
deliver to the Trustee an Officer's Certificate of a Servicing Officer
indicating the amount of any previous Advance determined by the Master
Servicer to be a Nonrecoverable Advance and identifying the related Mortgage
Loans(s), and their respective portions of such Nonrecoverable Advance.

      (b)    The Trustee shall withdraw funds from the Distribution Account
for distributions to Certificateholders and remittance to the Swap Account,
in the manner specified in this Agreement (and to withhold from the amounts
so withdrawn, the amount of any taxes that it is authorized to withhold
pursuant to the third paragraph of Section 8.11).   In addition, the Trustee
may from time to time make withdrawals from the Distribution Account for the
following purposes:

            (i)    to pay to itself the Trustee Fee for the related
      Distribution Date;

            (ii)   to pay to the Master Servicer as additional servicing
      compensation earnings on or investment income with respect to funds in
      the Distribution Account;

            (iii) to withdraw and return to the Master Servicer any amount
      deposited in the Distribution Account and not required to be deposited
      therein;

            (iv)   to reimburse the Trustee for any unreimbursed Advances made
      by it pursuant to Section 4.01(b) hereof, such right of reimbursement
      pursuant to this subclause (iv) being limited to (x) amounts received
      on the related Mortgage Loan(s) in respect of which any such Advance
      was made and (y) amounts not otherwise reimbursed to the Trustee
      pursuant to Section 3.08(a)(ii) hereof;

            (v)    to reimburse the Trustee for any Nonrecoverable Advance
      previously made by the Trustee pursuant to Section 4.01(b) hereof, such
      right of reimbursement pursuant to this subclause (v) being limited to
      amounts not otherwise reimbursed to the Trustee pursuant to Section
      3.08(a)(iii) hereof; and

             (vi)   to clear and terminate the Distribution Account upon
      termination of the Agreement pursuant to Section 9.01.

      (c)    The Trustee shall withdraw funds from the Carryover Reserve Fund
for distribution to the LIBOR Certificates and the Class C Certificates in
the manner specified in Section 4.02(e) (and to withhold from the amounts so
withdrawn the amount of any taxes that it


                                      67
<PAGE>


is authorized to retain pursuant to the third paragraph of Section 8.11).   In
addition, the Trustee may from time to time make withdrawals from the
Carryover Reserve Fund for the following purposes:

            (i)    to withdraw any amount deposited in the Carryover Reserve
      Fund and not required to be deposited therein; and

            (ii)   to clear and terminate the Carryover Reserve Fund upon the
      termination of this Agreement pursuant to Section 9.01.

      (d)    On the Business Day before the Class P Principal Distribution
Date, the Trustee shall transfer $100.00 from the Principal Reserve Fund to
the Distribution Account and shall distribute such amount to the Class P
Certificates on the Class P Principal Distribution Date.   Following the
distributions to be made in accordance with the preceding sentence, the
Trustee shall then terminate the Principal Reserve Fund.

      SECTION 3.09.      Maintenance of Hazard Insurance; Maintenance of
                        Primary Insurance Policies.

      (a)    The Master Servicer shall cause to be maintained, for each
Mortgage Loan, hazard insurance with extended coverage in an amount that is
at least equal to the lesser of (i) the maximum insurable value of the
improvements securing such Mortgage Loan or (ii) the greater of (y) the
outstanding principal balance of the Mortgage Loan and (z) an amount such
that the proceeds of such policy shall be sufficient to prevent the Mortgagor
and/or the mortgagee from becoming a co-insurer.   Each such policy of
standard hazard insurance shall contain, or have an accompanying endorsement
that contains, a standard mortgagee clause.   Any amounts collected by the
Master Servicer under any such policies (other than the amounts to be applied
to the restoration or repair of the related Mortgaged Property or amounts
released to the Mortgagor in accordance with the Master Servicer's normal
servicing procedures) shall be deposited in the Certificate Account.   Any
cost incurred by the Master Servicer in maintaining any such insurance shall
not, for the purpose of calculating monthly distributions to the
Certificateholders or remittances to the Trustee for their benefit, be added
to the principal balance of the Mortgage Loan, notwithstanding that the terms
of the Mortgage Loan so permit.   Such costs shall be recoverable by the
Master Servicer out of late payments by the related Mortgagor or out of
proceeds of liquidation of the Mortgage Loan or Subsequent Recoveries to the
extent permitted by Section 3.08.   It is understood and agreed that no
earthquake or other additional insurance is to be required of any Mortgagor
or maintained on property acquired in respect of a Mortgage other than
pursuant to such applicable laws and regulations as shall at any time be in
force and as shall require such additional insurance.   If the Mortgaged
Property is located at the time of origination of the Mortgage Loan in a
federally designated special flood hazard area and such area is participating
in the national flood insurance program, the Master Servicer shall cause
flood insurance to be maintained with respect to such Mortgage Loan.   Such
flood insurance shall be in an amount equal to the least of (i) the
outstanding principal balance of the related Mortgage Loan, (ii) the
replacement value of the improvements which are part of such Mortgaged
Property, and (iii) the maximum amount of such insurance available for the
related Mortgaged Property under the national flood insurance program.

      (b)    [Reserved].


                                      68
<PAGE>


      (c)    The Master Servicer shall not take any action which would result
in non-coverage under any applicable Primary Insurance Policy of any loss
which, but for the actions of the Master Servicer, would have been covered
thereunder.   The Master Servicer shall not cancel or refuse to renew any such
Primary Insurance Policy that is in effect at the date of the initial
issuance of the Certificates and is required to be kept in force hereunder
unless the replacement Primary Insurance Policy for such canceled or
non-renewed policy is maintained with a Qualified Insurer.

      Except with respect to any Lender PMI Mortgage Loans, the Master
Servicer shall not be required to maintain any Primary Insurance Policy
(i) with respect to any Mortgage Loan with a Loan-to-Value Ratio less than or
equal to 80% as of any date of determination or, based on a new appraisal,
the principal balance of such Mortgage Loan represents 80% or less of the new
appraised value or (ii) if maintaining such Primary Insurance Policy is
prohibited by applicable law.   With respect to the Lender PMI Mortgage Loans,
the Master Servicer shall maintain the Primary Insurance Policy for the life
of such Mortgage Loans, unless otherwise provided for in the related Mortgage
Note or prohibited by law.

      The Master Servicer agrees to effect the timely payment of the premiums
on each Primary Insurance Policy, and such costs not otherwise recoverable
shall be recoverable by the Master Servicer from the related proceeds of
liquidation and Subsequent Recoveries.

      (d)    In connection with its activities as Master Servicer of the
Mortgage Loans, the Master Servicer agrees to present on behalf of itself,
the Trustee and Certificateholders, claims to the insurer under any Primary
Insurance Policies and, in this regard, to take such reasonable action as
shall be necessary to permit recovery under any Primary Insurance Policies
respecting defaulted Mortgage Loans.   Any amounts collected by the Master
Servicer under any Primary Insurance Policies shall be deposited in the
Certificate Account.

      SECTION 3.10.      Enforcement of Due-on-Sale Clauses; Assumption
                        Agreements.

      (a)    Except as otherwise provided in this Section, when any property
subject to a Mortgage has been conveyed by the Mortgagor, the Master Servicer
shall to the extent that it has knowledge of such conveyance, enforce any
due-on-sale clause contained in any Mortgage Note or Mortgage, to the extent
permitted under applicable law and governmental regulations, but only to the
extent that such enforcement will not adversely affect or jeopardize coverage
under any Required Insurance Policy.   Notwithstanding the foregoing, the
Master Servicer is not required to exercise such rights with respect to a
Mortgage Loan if the Person to whom the related Mortgaged Property has been
conveyed or is proposed to be conveyed satisfies the terms and conditions
contained in the Mortgage Note and Mortgage related thereto and the consent
of the mortgagee under such Mortgage Note or Mortgage is not otherwise so
required under such Mortgage Note or Mortgage as a condition to such
transfer.   In the event that the Master Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is
otherwise permitted hereunder, the Master Servicer is authorized, subject to
Section 3.10(b), to take or enter into an assumption and modification
agreement from or with the person to whom such property has been or is about
to be conveyed, pursuant to which such person becomes liable under the
Mortgage Note and, unless prohibited by applicable state law, the Mortgagor
remains liable thereon, provided that the Mortgage Loan shall continue to be
covered (if so covered


                                       69
<PAGE>


before the Master Servicer enters such agreement) by the applicable Required
Insurance Policies.   The Master Servicer, subject to Section 3.10(b), is also
authorized with the prior approval of the insurers under any Required
Insurance Policies to enter into a substitution of liability agreement with
such Person, pursuant to which the original Mortgagor is released from
liability and such Person is substituted as Mortgagor and becomes liable
under the Mortgage Note.   Notwithstanding the foregoing, the Master Servicer
shall not be deemed to be in default under this Section by reason of any
transfer or assumption which the Master Servicer reasonably believes it is
restricted by law from preventing, for any reason whatsoever.

       (b)    Subject to the Master Servicer's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.10(a), in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such
Person is to enter into an assumption agreement or modification agreement or
supplement to the Mortgage Note or Mortgage that requires the signature of
the Trustee, or if an instrument of release signed by the Trustee is required
releasing the Mortgagor from liability on the Mortgage Loan, the Master
Servicer shall prepare and deliver or cause to be prepared and delivered to
the Trustee for signature and shall direct, in writing, the Trustee to
execute the assumption agreement with the Person to whom the Mortgaged
Property is to be conveyed and such modification agreement or supplement to
the Mortgage Note or Mortgage or other instruments as are reasonable or
necessary to carry out the terms of the Mortgage Note or Mortgage or
otherwise to comply with any applicable laws regarding assumptions or the
transfer of the Mortgaged Property to such Person.   In connection with any
such assumption, no material term of the Mortgage Note may be changed.   In
addition, the substitute Mortgagor and the Mortgaged Property must be
acceptable to the Master Servicer in accordance with its underwriting
standards as then in effect.   Together with each such substitution,
assumption or other agreement or instrument delivered to the Trustee for
execution by it, the Master Servicer shall deliver an Officer's Certificate
signed by a Servicing Officer stating that the requirements of this
subsection have been met in connection therewith.   The Master Servicer shall
notify the Trustee that any such substitution or assumption agreement has
been completed by forwarding to the Trustee the original of such substitution
or assumption agreement, which in the case of the original shall be added to
the related Mortgage File and shall, for all purposes, be considered a part
of such Mortgage File to the same extent as all other documents and
instruments constituting a part thereof.   Any fee collected by the Master
Servicer for entering into an assumption or substitution of liability
agreement will be retained by the Master Servicer as additional servicing
compensation.

      SECTION 3.11.      Realization Upon Defaulted Mortgage Loans; Repurchase
                        of Certain Mortgage Loans.

      (a)    The Master Servicer shall use reasonable efforts to foreclose
upon or otherwise comparably convert the ownership of properties securing
such of the Mortgage Loans as come into and continue in default and as to
which no satisfactory arrangements can be made for collection of delinquent
payments.   In connection with such foreclosure or other conversion, the
Master Servicer shall follow such practices and procedures as it shall deem
necessary or advisable and as shall be normal and usual in its general
mortgage servicing activities and meet the requirements of the insurer under
any Required Insurance Policy; provided, however, that the Master Servicer
shall not be required to expend its own funds in connection with any
foreclosure or towards the restoration of any property unless it shall
determine (i) that such restoration and/or foreclosure will increase the
proceeds of liquidation of the Mortgage Loan after reimbursement


                                      70
<PAGE>


to itself of such expenses and (ii) that such expenses will be recoverable to
it through the proceeds of liquidation of the Mortgage Loan and Subsequent
Recoveries (respecting which it shall have priority for purposes of
withdrawals from the Certificate Account).   The Master Servicer shall be
responsible for all other costs and expenses incurred by it in any such
proceedings; provided, however, that it shall be entitled to reimbursement
thereof from the proceeds of liquidation of the Mortgage Loan and Subsequent
Recoveries with respect to the related Mortgaged Property, as provided in the
definition of Liquidation Proceeds.   If the Master Servicer has knowledge
that a Mortgaged Property which the Master Servicer is contemplating
acquiring in foreclosure or by deed in lieu of foreclosure is located within
a 1 mile radius of any site listed in the Expenditure Plan for the Hazardous
Substance Clean Up Bond Act of 1984 or other site with environmental or
hazardous waste risks known to the Master Servicer, the Master Servicer will,
prior to acquiring the Mortgaged Property, consider such risks and only take
action in accordance with its established environmental review procedures.

      With respect to any REO Property, the deed or certificate of sale shall
be taken in the name of the Trustee for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders.   The
Trustee's name shall be placed on the title to such REO Property solely as
the Trustee hereunder and not in its individual capacity.   The Master
Servicer shall ensure that the title to such REO Property references the
Pooling and Servicing Agreement and the Trustee's capacity thereunder.
Pursuant to its efforts to sell such REO Property, the Master Servicer shall
either itself or through an agent selected by the Master Servicer protect and
conserve such REO Property in the same manner and to such extent as is
customary in the locality where such REO Property is located and may,
incident to its conservation and protection of the interests of the
Certificateholders, rent the same, or any part thereof, as the Master
Servicer deems to be in the best interest of the Certificateholders for the
period prior to the sale of such REO Property.   The Master Servicer shall
prepare for and deliver to the Trustee a statement with respect to each REO
Property that has been rented showing the aggregate rental income received
and all expenses incurred in connection with the maintenance of such REO
Property at such times as is necessary to enable the Trustee to comply with
the reporting requirements of the REMIC Provisions.   The net monthly rental
income, if any, from such REO Property shall be deposited in the Certificate
Account no later than the close of business on each Determination Date.   The
Master Servicer shall perform the tax reporting and withholding required by
Sections 1445 and 6050J of the Code with respect to foreclosures and
abandonments, the tax reporting required by Section 6050H of the Code with
respect to the receipt of mortgage interest from individuals and any tax
reporting required by Section 6050P of the Code with respect to the
cancellation of indebtedness by certain financial entities, by preparing such
tax and information returns as may be required, in the form required, and
delivering the same to the Trustee for filing.

      In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property
as soon as practicable in a manner that maximizes the Liquidation Proceeds
thereof, but in no event later than three years after its acquisition by the
Trust Fund.   In that event, the Trustee shall have been supplied with an
Opinion of Counsel to the effect that the holding by the Trust Fund of such
Mortgaged Property subsequent to a three-year period, if applicable, will not
result in the imposition of taxes on "prohibited transactions" of any REMIC
hereunder as defined in Section 860F of the Code or cause any REMIC hereunder
to fail to qualify as a REMIC at any time that any Certificates are


                                      71
<PAGE>


outstanding, and that the Trust Fund may continue to hold such Mortgaged
Property (subject to any conditions contained in such Opinion of Counsel)
after the expiration of such three-year period.   Notwithstanding any other
provision of this Agreement, no Mortgaged Property acquired by the Trust Fund
shall be rented (or allowed to continue to be rented) or otherwise used for
the production of income by or on behalf of the Trust Fund in such a manner
or pursuant to any terms that would (i) cause such Mortgaged Property to fail
to qualify as "foreclosure property" within the meaning of Section 860G(a)(8)
of the Code or (ii) subject any REMIC hereunder to the imposition of any
federal, state or local income taxes on the income earned from such Mortgaged
Property under Section 860G(c) of the Code or otherwise, unless the Master
Servicer has agreed to indemnify and hold harmless the Trust Fund with
respect to the imposition of any such taxes.

      In the event of a default on a Mortgage Loan one or more of whose
obligor is not a United States Person, as that term is defined in
Section 7701(a)(30) of the Code, in connection with any foreclosure or
acquisition of a deed in lieu of foreclosure (together, "foreclosure") in
respect of such Mortgage Loan, the Master Servicer will cause compliance with
the provisions of Treasury Regulation Section 1.1445-2(d)(3) (or any
successor thereto) necessary to assure that no withholding tax obligation
arises with respect to the proceeds of such foreclosure except to the extent,
if any, that proceeds of such foreclosure are required to be remitted to the
obligors on such Mortgage Loan.

      The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of
bringing such a proceeding.   The income earned from the management of any REO
Properties, net of reimbursement to the Master Servicer for expenses incurred
(including any property or other taxes) in connection with such management
and net of unreimbursed Master Servicing Fees, Advances and Servicing
Advances, shall be applied to the payment of principal of and interest on the
related defaulted Mortgage Loans (with interest accruing as though such
Mortgage Loans were still current) and all such income shall be deemed, for
all purposes in this Agreement, to be payments on account of principal and
interest on the related Mortgage Notes and shall be deposited into the
Certificate Account.   To the extent the net income received during any
calendar month is in excess of the amount attributable to amortizing
principal and accrued interest at the related Mortgage Rate on the related
Mortgage Loan for such calendar month, such excess shall be considered to be
a partial prepayment of principal of the related Mortgage Loan.

      The proceeds from any liquidation of a Mortgage Loan, as well as any
income from an REO Property, will be applied in the following order of
priority: first, to reimburse the Master Servicer for any related
unreimbursed Servicing Advances and Master Servicing Fees; second, to
reimburse the Master Servicer or the Trustee for any unreimbursed Advances;
third, to reimburse the Certificate Account for any Nonrecoverable Advances
(or portions thereof) that were previously withdrawn by the Master Servicer
or the Trustee pursuant to Section 3.08(a)(iii) that related to such Mortgage
Loan; fourth, to accrued and unpaid interest (to the extent no Advance has
been made for such amount or any such Advance has been reimbursed) on the
Mortgage Loan or related REO Property, at the Adjusted Net Mortgage Rate to
the Due Date occurring in the month in which such amounts are required to be
distributed; and fifth, as a recovery of principal of the Mortgage Loan.
Excess Proceeds, if any, from the liquidation of a Liquidated


                                      72
<PAGE>


Mortgage Loan will be retained by the Master Servicer as additional servicing
compensation pursuant to Section 3.14.

      The Master Servicer, in its sole discretion, shall have the right to
purchase for its own account from the Trust Fund any Mortgage Loan which is
151 days or more delinquent at a price equal to the Purchase Price; provided,
however, that the Master Servicer may only exercise this right on or before
the next to the last day of the calendar month which such Mortgage Loan
became 151 days delinquent (such month, the "Eligible Repurchase Month");
provided further, that any such Mortgage Loan which becomes current but
thereafter becomes delinquent may be purchased by the Master Servicer
pursuant to this Section in any ensuing Eligible Repurchase Month.   The
Master Servicer, in its sole discretion, shall also have the right to
purchase for its own account from the Trust Fund at a price equal to the
Purchase Price any Eligible EPD Protected Mortgage Loan.   The Master
Servicer's right to purchase any such Eligible EPD Protected Mortgage Loan
shall expire on the 270th day following the date on which such Mortgage Loan
became an Eligible EPD Protected Mortgage Loan.   The Purchase Price for any
Mortgage Loan purchased under this Section 3.11 shall be deposited in the
Certificate Account and the Trustee, upon receipt of a certificate from the
Master Servicer in the form of Exhibit N to this Agreement, shall release or
cause to be released to the purchaser of such Mortgage Loan the related
Mortgage File and shall execute and deliver such instruments of transfer or
assignment prepared by the purchaser of such Mortgage Loan, in each case
without recourse, as shall be necessary to vest in the purchaser of such
Mortgage Loan any Mortgage Loan released pursuant hereto and the purchaser of
such Mortgage Loan shall succeed to all the Trustee's right, title and
interest in and to such Mortgage Loan and all security and documents related
thereto.   Such assignment shall be an assignment outright and not for
security.   The purchaser of such Mortgage Loan shall thereupon own such
Mortgage Loan, and all security and documents, free of any further obligation
to the Trustee or the Certificateholders with respect thereto.

      (b)    Countrywide may agree to a modification of any Mortgage Loan (the
"Modified Mortgage Loan") if (i) the modification is in lieu of a refinancing
and (ii) the Mortgage Rate on the Modified Mortgage Loan is approximately a
prevailing market rate for newly originated mortgage loans having similar
terms and (iii) Countrywide purchases the Modified Mortgage Loan from the
Trust Fund as described below. Effective immediately after the modification,
and, in any event, on the same Business Day on which the modification occurs,
all interest of the Trustee in the Modified Mortgage Loan shall automatically
be deemed transferred and assigned to Countrywide and all benefits and
burdens of ownership thereof, including the right to accrued interest thereon
from the date of modification and the risk of default thereon, shall pass to
Countrywide. The Master Servicer shall promptly deliver to the Trustee a
certification of a Servicing Officer to the effect that all requirements of
this paragraph have been satisfied with respect to the Modified Mortgage
Loan.   For federal income tax purposes, the Trustee shall account for such
purchase as a prepayment in full of the Modified Mortgage Loan.

       Countrywide shall remit to the Master Servicer and the Master Service
shall deposit the Purchase Price for any Modified Mortgage Loan in the
Certificate Account pursuant to Section 3.05 within one Business Day after
the purchase of the Modified Mortgage Loan. Upon receipt by the Trustee of
written notification of any such deposit signed by a Servicing Officer, the
Trustee shall release to Countrywide the related Mortgage File and shall
execute and deliver such instruments of transfer or assignment, in each case
without recourse, as shall be necessary to vest in Countrywide any Modified
Mortgage Loan previously transferred and assigned pursuant


                                      73
<PAGE>


hereto. Countrywide covenants and agrees to indemnify the Trust Fund against
any liability for any "prohibited transaction" taxes and any related
interest, additions, and penalties imposed on the Trust Fund established
hereunder as a result of any modification of a Mortgage Loan effected
pursuant to this subsection (b), any holding of a Modified Mortgage Loan by
the Trust Fund or any purchase of a Modified Mortgage Loan by Countrywide
(but such obligation shall not prevent Countrywide or any other appropriate
Person from in good faith contesting any such tax in appropriate proceedings
and shall not prevent Countrywide from withholding payment of such tax, if
permitted by law, pending the outcome of such proceedings). Countrywide shall
have no right of reimbursement for any amount paid pursuant to the foregoing
indemnification, except to the extent that the amount of any tax, interest,
and penalties, together with interest thereon, is refunded to the Trust Fund
or Countrywide.

      SECTION 3.12.      Trustee to Cooperate; Release of Mortgage Files.

      Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, the Master Servicer will immediately
notify the Trustee by delivering, or causing to be delivered a "Request for
Release" substantially in the form of Exhibit N of this Agreement.   Upon
receipt of such request, the Trustee shall promptly release the related
Mortgage File to the Master Servicer, and the Trustee shall at the Master
Servicer's direction execute and deliver to the Master Servicer the request
for reconveyance, deed of reconveyance or release or satisfaction of mortgage
or such instrument releasing the lien of the Mortgage in each case provided
by the Master Servicer, together with the Mortgage Note with written evidence
of cancellation on the Mortgage Note.   The Master Servicer is authorized to
cause the removal from the registration on the MERS(R) System of such Mortgage
and to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation or of partial or full release.   Expenses incurred in connection
with any instrument of satisfaction or deed of reconveyance shall be
chargeable to the related Mortgagor.   From time to time and as shall be
appropriate for the servicing or foreclosure of any Mortgage Loan, including
for such purpose, collection under any policy of flood insurance, any
fidelity bond or errors or omissions policy, or for the purposes of effecting
a partial release of any Mortgaged Property from the lien of the Mortgage or
the making of any corrections to the Mortgage Note or the Mortgage or any of
the other documents included in the Mortgage File, the Trustee shall, upon
delivery to the Trustee of a Request for Release in the form of Exhibit M
signed by a Servicing Officer, release the Mortgage File to the Master
Servicer.   Subject to the further limitations set forth below, the Master
Servicer shall cause the Mortgage File or documents so released to be
returned to the Trustee when the need therefor by the Master Servicer no
longer exists, unless the Mortgage Loan is liquidated and the proceeds
thereof are deposited in the Certificate Account, in which case the Master
Servicer shall deliver to the Trustee a Request for Release in the form of
Exhibit N, signed by a Servicing Officer.

      If the Master Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this
Agreement, the Master Servicer shall deliver or cause to be delivered to the
Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents necessary to effectuate such foreclosure or
any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to
enforce any other remedies or rights provided by the Mortgage Note or the
Mortgage or otherwise available at law or in equity.

      SECTION 3.13.      Documents, Records and Funds in Possession of Master
                        Servicer to be Held for the Trustee.

      Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully
to the Trustee for any funds received by the Master Servicer or which
otherwise are collected by the Master Servicer as Liquidation Proceeds,
Insurance Proceeds or Subsequent Recoveries in respect of any Mortgage Loan.
All Mortgage Files and funds collected or held by, or under the control of,
the Master Servicer in respect of any Mortgage Loans, whether from the
collection of principal and interest payments or from Liquidation Proceeds
and any Subsequent Recoveries, including but not limited to, any funds on
deposit in the Certificate Account, shall be held by the Master Servicer for
and on behalf of the Trustee and shall be and remain the sole and exclusive
property of the Trustee, subject to the applicable provisions of this
Agreement.   The Master Servicer also agrees that it shall not create, incur
or subject any Mortgage File or any funds that are deposited in the
Certificate Account, Distribution Account or any Escrow Account, or any funds
that otherwise are or may become due or payable to the Trustee for the
benefit of the Certificateholders, to any claim, lien, security interest,
judgment, levy, writ of attachment or other encumbrance, or assert by legal
action or otherwise any claim or right of setoff against any Mortgage File or
any funds collected on, or in connection with, a Mortgage Loan, except,
however, that the Master Servicer shall be entitled to set off against and
deduct from any such funds any amounts that are properly due and payable to
the Master Servicer under this Agreement.

      SECTION 3.14.      Servicing Compensation.

      As compensation for its activities hereunder, the Master Servicer shall
be entitled to retain or withdraw from the Certificate Account an amount
equal to the Master Servicing Fee; provided, that the aggregate Master
Servicing Fee with respect to any Distribution Date shall be reduced (i) by
an amount equal to the aggregate of the Prepayment Interest Shortfalls, if
any, with respect to such Distribution Date, but not by more than the
Compensating Interest for that Distribution Date, and (ii) with respect to
the first Distribution Date, an amount equal to any amount to be deposited
into the Distribution Account by the Depositor pursuant to Section 2.01(a)
and not so deposited.

      Additional servicing compensation in the form of Excess Proceeds,
Prepayment Interest Excess, assumption fees, late payment charges and all
income and gain net of any losses realized from Permitted Investments shall
be retained by the Master Servicer to the extent not required to be deposited
in the Certificate Account pursuant to Section 3.05.   The Master Servicer
shall be required to pay all expenses incurred by it in connection with its
master servicing activities hereunder (including payment of any premiums for
hazard insurance and any Primary Insurance Policy and maintenance of the
other forms of insurance coverage required by this Agreement) and shall not
be entitled to reimbursement therefor except as specifically provided in this
Agreement.

comparable regulatory authorities supervising Holders and/or Certificate
Owners and the examiners and supervisory agents of the OTS, the FDIC and such
other authorities, access to the documentation regarding the Mortgage Loans
required by applicable regulations of the OTS and the FDIC.   Such access
shall be afforded without charge, but only upon reasonable and prior written
request and during normal business hours at the offices designated by the
Master Servicer.   Nothing in this Section shall limit the obligation of the
Master Servicer to observe any applicable law prohibiting disclosure of
information regarding the Mortgagors and the failure of the Master Servicer
to provide access as provided in this Section as a result of such obligation
shall not constitute a breach of this Section.

      The Master Servicer acknowledges that as part of its servicing
activities, the Master Servicer shall fully furnish, in accordance with the
Fair Credit Reporting Act and its implementing regulations, accurate and
complete information (i.e., favorable and unfavorable) on its borrower credit
files related to the Mortgage Loans to Equifax, Experian and Trans Union
Credit Information Company (three of the nationally recognized credit
bureaus) on a monthly basis.

      SECTION 3.16.      Annual Statement as to Compliance.

      (a)    The Master Servicer shall deliver to the Depositor and the
Trustee on or before March 15 of each year, commencing with its 2007 fiscal

primary servicing agreement, has been made under such officer's supervision
and (ii) to the best of such officer's knowledge, based on such review, such
Subservicer has fulfilled all its obligations under the applicable
Subservicing Agreement or primary servicing agreement, in all material

      (c)    The Trustee shall forward a copy of each such statement to each

      SECTION 3.17.      Errors and Omissions Insurance; Fidelity Bonds.


                                      76
<PAGE>


      The Master Servicer shall for so long as it acts as master servicer
under this Agreement, obtain and maintain in force (a) a policy or policies
of insurance covering errors and omissions in the performance of its
obligations as Master Servicer hereunder and (b) a fidelity bond in respect
of its officers, employees and agents.   Each such policy or policies and bond
shall, together, comply with the requirements from time to time of FNMA or
FHLMC for persons performing servicing for mortgage loans purchased by FNMA
or FHLMC.   In the event that any such policy or bond ceases to be in effect,
the Master Servicer shall obtain a comparable replacement policy or bond from
an insurer or issuer, meeting the requirements set forth above as of the date
of such replacement.

      SECTION 3.18.      Notification of Adjustments.

      On each Adjustment Date, the Master Servicer shall make interest rate
adjustments for each Mortgage Loan in compliance with the requirements of the
related Mortgage and Mortgage Note and applicable regulations.   The Master
Servicer shall execute and deliver the notices required by each Mortgage and
Mortgage Note and applicable regulations regarding interest rate
adjustments.   The Master Servicer also shall provide timely notification to
the Trustee of all applicable data and information regarding such interest
rate adjustments and the Master Servicer's methods of implementing such
interest rate adjustments.   Upon the discovery by the Master Servicer or the
Trustee that the Master Servicer has failed to adjust or has incorrectly
adjusted a Mortgage Rate or a monthly payment pursuant to the terms of the
related Mortgage Note and Mortgage, the Master Servicer shall immediately
deposit in the Certificate Account from its own funds the amount of any
interest loss caused thereby without reimbursement therefor; provided,
however, the Master Servicer shall be held harmless with respect to any
interest rate adjustments made by any servicer prior to the Master Servicer.

      SECTION 3.19.      The Swap Contract.

      Countrywide shall cause The Bank of New York to enter into the Swap

and interest in and to the interest rate swap transaction evidenced by the

transaction to be assumed by, the Swap Contract Administrator, on the terms
and conditions set forth in the Swap Contract Assignment Agreement.   The
Trustee's rights to receive certain proceeds of the Swap Contract as provided
in the Swap Contract Administration Agreement shall be rights of the Trustee
as Swap Trustee hereunder, shall be an asset of the Swap Trust and shall not
be an asset of the Trust Fund nor of any REMIC.   The Swap Trustee shall
deposit any amounts received from time to time from the Swap Contract
Administrator with respect to the Swap Contract into the Swap Account.   The
Master Servicer shall deposit any amounts received on behalf of the Swap
Trustee from time to time with respect to the Swap Contract into the Swap
Account.

      On the Business Day preceding each Distribution Date, the Swap Trustee
shall notify the Swap Contract Administrator of any amounts distributable to
the Covered Certificates pursuant to Section 4.02(d)(iii) through (viii) that
will remain unpaid following all distributions to be made on such
Distribution Date pursuant to Section 4.02(a) through (c).

<PAGE>


      No later than two Business Days following each Distribution Date, the
Trustee shall provide the Swap Contract Administrator with information
regarding the aggregate Class Certificate Balance of the LIBOR Certificates
after all distributions on such Distribution Date.

      Upon the Swap Contract Administrator obtaining actual knowledge of the
rating of the Swap Counterparty falling below the Approved Rating Thresholds
(as defined in the Swap Contract) or upon the Swap Contract Administrator
obtaining actual knowledge of a Ratings Event (as defined in the Swap
Contract), the Swap Trustee shall direct the Swap Contract Administrator to
(i) demand payment of the Delivery Amount (as defined in the ISDA Credit
Support Annex) on each Valuation Date (as defined in the ISDA Credit Support
Annex) and to perform its other obligations in accordance with the ISDA
Credit Support Annex or (ii) take such other action required under the Swap
Contract.   If a Delivery Amount is demanded, the Swap Trustee shall set up an
account in accordance with Section 4.09 to hold cash or other eligible
investments pledged under the ISDA Credit Support Annex.   Any cash or other
eligible investments pledged under the ISDA Credit Support Annex shall not be
part of the Distribution Account or the Swap Account unless they are applied
in accordance with the ISDA Credit Support Annex to make a payment due to the
Swap Contract Administrator pursuant to the Swap Contract.   If Eligible
Credit Support (as defined in the ISDA Credit Support Annex) with a value
equal to the Delivery Amount is not delivered, the Swap Trustee shall direct
the Swap Contract Administrator to notify the Swap Counterparty of such
failure.

       Upon the Swap Trustee obtaining actual knowledge of an Event of Default
(as defined in the Swap Contract) or Termination Event (as defined in the
Swap Contract) for which the Swap Contract Administrator has the right to
designate an Early Termination Date (as defined in the Swap Contract), the
Swap Trustee shall act at the written direction of the Depositor as to
whether to direct the Swap Contract Administrator to designate an Early
Termination Date; provided, however, that the Swap Trustee shall provide
written notice to each Rating Agency following the Event of Default or
Termination Event.   Upon the termination of the Swap Contract under the
circumstances contemplated by this Section 3.19, the Swap Trustee shall use
its reasonable best efforts to enforce the rights of the Swap Contract
Administrator as may be permitted by the terms of the Swap Contract and
consistent with the terms hereof, and Countrywide shall assist the Swap
Contract Administrator in procuring a replacement swap contract with terms
approximating those of the original Swap Contract.

            In the event that the swap counterparty in respect of a
replacement swap contract pays any upfront amount to the Swap Contract
Administrator in connection with entering into the replacement swap contract
and such upfront amount is received by the Swap Contract Administrator prior
to the Distribution Date on which any Swap Termination Payment will be
payable to the Swap Counterparty in respect of the original Swap Contract, a
portion of that upfront amount equal to the lesser of (x) that upfront amount
and (y) the amount of the Swap Termination Payment due to the Swap
Counterparty in respect of the original Swap Contract   (the "Adjusted
Replacement Upfront Amount") shall be included in Interest Funds for Loan
Group 1 and Loan Group 2 pro rata based on their respective Interest Funds
for that Distribution Date and any upfront amount in excess of the Adjusted
Replacement Upfront Amount shall be distributed to Countrywide and will not
be available to make distributions in respect of any Class of Certificates.
Any upfront amount paid to the Swap Contract Administrator by the swap
counterparty in respect of a replacement swap contract after the Distribution
Date on which any Swap Termination Payment will be payable to the Swap
Counterparty in respect of the original


                                      78
<PAGE>


Swap Contract shall be retained by the Swap Contract Administrator and
remitted to the Swap Trustee on subsequent Distribution Dates up to and
including the Swap Contract Termination Date to pay any amounts distributable
to the Covered Certificates pursuant to Section 4.02(d)(iii) through (viii)
that will remain unpaid following all distributions to be made on such
Distribution Date pursuant to Section 4.02(a) through (c).

      Any portion of any Net Swap Payment or Swap Termination Payment payable
by the Swap Counterparty and not remitted by the Swap Contract Administrator
to the Swap Trustee with respect to any Distribution Date will be remitted to
Countrywide and will not be available to make distributions in respect of any
Class of Certificates.

      The Swap Counterparty shall be an express third party beneficiary of
this Agreement for the purpose of enforcing the provisions hereof to the
extent of the Swap Counterparty's rights explicitly specified herein as if a
party hereto.

      SECTION 3.20.      Prepayment Charges.

      (a)    Notwithstanding anything in this Agreement to the contrary, in
the event of a Principal Prepayment in full or in part of a Mortgage Loan,
the Master Servicer may not waive any Prepayment Charge or portion thereof
required by the terms of the related Mortgage Note unless (i) such Mortgage
Loan is in default or the Master Servicer believes that such a default is
imminent, and the Master Servicer determines that such waiver would maximize
recovery of Liquidation Proceeds for such Mortgage Loan, taking into account
the value of such Prepayment Charge, or (ii) (A) the enforceability thereof
is limited (1) by bankruptcy, insolvency, moratorium, receivership, or other
similar law relating to creditors' rights generally or (2) due to
acceleration in connection with a foreclosure or other involuntary payment,
or (B) the enforceability is otherwise limited or prohibited by applicable
law.   In the event of a Principal Prepayment in full or in part with respect
to any Mortgage Loan, the Master Servicer shall deliver to the Trustee an
Officer's Certificate substantially in the form of Exhibit T no later than
the third Business Day following the immediately succeeding Determination
Date with a copy to the Class P Certificateholders.   If the Master Servicer
has waived or does not collect all or a portion of a Prepayment Charge
relating to a Principal Prepayment in full or in part due to any action or
omission of the Master Servicer, other than as provided above, the Master
Servicer shall deliver to the Trustee, together with the Principal Prepayment
in full or in part, the amount of such Prepayment Charge (or such portion
thereof as had been waived) for deposit into the Certificate Account (not
later than 1:00 p.m. Pacific time on the immediately succeeding Master
Servicer Advance Date, in the case of such Prepayment Charge) for
distribution in accordance with the terms of this Agreement.
