Class 1-A11, Class 1-A12, Class 1-A13, Class 1-A14, Class 1-A15, Class 1-A17,
Class 1-A19, Class 1-A20, Class 1-AX and Class A-R Certificates will be 6.00%,
(ii) in the case of the Class 1-A16 Certificates will be 5.875%, (iii) in the
case of the Class 1-A10 Certificates will be 5.750% and (iv) in the case of the
Class 1-A21, Class 2-A1 and Class 2-AX Certificates will be 5.50%. In the case
of the Class 1-A1 Certificates, the Certificate Rate with respect to the first
Distribution Date will be 5.92%, and as to any Distribution Date thereafter, the
Certificate Rate on the Class 1-A1 Certificates will equal the lesser of (A)
0.60% plus LIBOR and (B) 20.00%, but not less than 0.60%. In the case of the
Class 1-A2 Certificates, the Certificate Rate with respect to the first
Distribution Date will be 0.08%, and as to any Distribution Date thereafter, the
Certificate Rate on the Class 1-A2 Certificates will equal the greater of (A)
5.40% minus LIBOR and (B) 0.00%. In the case of the Class 1-A8 Certificates, the

(ii) with respect to any Distribution Date thereafter but prior to the interest

LIBOR and (B) 9.50%, but not less than 5.75% and (iii) commencing with the
interest accrual period relating to the Distribution Date in May 2010 and with
respect to any Distribution Date thereafter, 5.75%. In the case of the Class
1-A18, Class 1-A22, Class 1-A23 and Class 1-A24 Certificates, the Certificate
Rates will equal a per annum rate equal to , for any Distribution Date (i) prior
to the Credit Support Depletion Date, 6.000%, 5.625%, 5.750% and 5.875%,
respectively, or (ii) on or after the Credit Support Depletion Date, the sum of
(A) 5.50% and (B) a fraction, the numerator of which is the product of (1) 12,
(2) the interest accrued on the Class 1-A17 Certificates (without taking account
of any exchanges) for such Distribution Date and (3)(a) 14,881,000, (b)
3,720,250, (c) 7,440,500 and (d) 11,160,750, respectively, and the denominator

of the Class 1-A18, Class 1-A22, Class 1-A23 or Class 1-A24 Certificates is
reduced to zero while any such Class of Certificates is entitled to receive
interest amounts from the portion of the Class 1-A17 Certificates exchanged for
such Class, such interest entitlement will not be expressed as a Certificate
Rate and such Class will be entitled to interest amounts that would otherwise be
paid to the Class 1-A17 Certificates exchanged for such Class. With respect to
each Class of Subordinated Certificates, the per annum rate of interest will
equal the fraction, expressed as a percentage, (I) the numerator of which will
equal the sum of (i) the product of (x) 6.00% and (y) the Group One Subordinated
Amount, and (ii) the product of (x) 5.50% and (y) the Group Two Subordinated
Amount and (II) the denominator of which will equal the sum of the Group One
Subordinated Amount and the Group Two Subordinated Amount. For federal income
tax purposes, the Certificate Rate on each Class of Subordinate Certificates can
be expressed as a per annum rate equal to the weighted average of the interest
rates on the Lower-Tier REMIC Regular Interests ending with the designation "A"
weighted on the basis of their principal amounts immediately prior to such
Distribution Date. Interest with respect

of MERS for purposes of the system of recording transfers of beneficial
ownership of mortgages maintained by MERS.

The ownership of each Mortgage Note, the Mortgage and the contents of the
related Mortgage File is vested in the Trustee. Neither the Depositor nor the
Servicer shall take any action inconsistent with such ownership and shall not
claim any ownership interest therein. The Depositor and the Servicer shall
respond to any third party inquiries with respect to ownership of the Mortgage
Loans by stating that such ownership is held by the Trustee on behalf of the
Certificateholders. Mortgage documents relating to the Mortgage Loans not

Sub-Servicer, for the benefit of the Trustee as the owner thereof, and the

File so retained is for the sole purpose of servicing the related Mortgage Loan,
and such retention and possession by the Servicer or such Sub-Servicer is in a
custodial capacity only. The Depositor agrees to take no action inconsistent
with the Trustee's ownership of the Mortgage Loans, to promptly indicate to all
inquiring parties that the Mortgage Loans have been sold and to claim no
ownership interest in the Mortgage Loans. Each Mortgage File and the mortgage
documents relating to the Mortgage Loans contain proprietary business
information of the Servicer and its customers. The Trustee and the Depositor
agree that they will not use such information for business purposes without the
express written consent of the Servicer and that all such information shall be
kept strictly confidential.

It is the intention of this Agreement that the conveyance of the
Depositor's right, title and interest in and to the Trust Fund pursuant to this
Agreement shall constitute a purchase and sale and not a loan. If a conveyance
of Mortgage Loans from any Seller to the Depositor is characterized as a pledge
and not a sale, then the Depositor shall be deemed to have transferred to the
Trustee all of the Depositor's right, title and interest in, to and under the
obligations of such Seller deemed to be secured by said pledge; and it is the
intention of this Agreement that the Depositor shall also be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title, and interest in, to and under the obligations of such
Seller to the Depositor deemed to be secured by said pledge and that the Trustee
shall be deemed to be an independent custodian for purposes of perfection of the
security interest granted to the Depositor. If the conveyance of the Mortgage
Loans from the Depositor to the Trustee is characterized as a pledge, it is the
intention of this Agreement that this Agreement shall constitute a security
agreement under applicable law, and that the Depositor shall be deemed to have
granted to the Trustee a first priority security interest in all of the
Depositor's right, title and interest in, to and under the Mortgage Loans, all
payments of principal of or interest on such Mortgage Loans, all other rights
relating to and payments made in respect of the Trust Fund, and all proceeds of
any thereof. If the trust created by this Agreement

48

<PAGE>

terminates prior to the satisfaction of the claims of any Person in any
Certificates, the security interest created hereby shall continue in full force
and effect and the Trustee shall be deemed to be the collateral agent for the
benefit of such Person.

In addition to the conveyance made in the first paragraph of this Section
2.01, the Depositor does hereby convey, assign and set over to the Trustee all
of its right, title and interest in that portion of the Trust Fund described in
items (ii), (iii), (iv) and (v) of the definition thereof and further assigns to
the Trustee for the benefit of the Certificateholders those representations and
warranties of the Seller contained in the Sale Agreement and described in
Section 3.01 hereof and the benefit of the repurchase obligations of the Seller
described in Sections 2.02 and 3.01 hereof and the obligations of the Seller
contained in the Sale Agreement to take, at the request of the Depositor or the
Trustee, all action on its part which is reasonably necessary to ensure the
enforceability of a Mortgage Loan.

The parties hereto agree and understand that it is not intended that any
mortgage loan be included in the Trust that is any of (i) a "High-Cost Home

Cost Home Loan Law effective January 1, 2005.

Section 2.02 Acceptance by Trustee. Except as set forth in the Exception
Report delivered contemporaneously herewith (the "Exception Report"), the
Trustee acknowledges receipt by the Custodian on the Trustee's behalf of the
Mortgage Note for each Mortgage Loan and delivery of a Mortgage File (but does
not acknowledge receipt of all documents required to be included in such
Mortgage File) with respect to each Mortgage Loan and declares that the
Custodian holds and will hold on the Trustee's behalf such documents and any
other documents constituting a part of the Mortgage Files delivered to it in
trust for the use and benefit of all present and future Certificateholders. The
Depositor will cause the Seller to repurchase any Mortgage Loans to which an
exception was taken in the Exception Report unless such exception is cured to
the satisfaction of the Trustee within 45 Business Days of the Closing Date. The
Trustee may accept delivery of such Mortgage Files by the Custodian on its
behalf. The Custodian will deliver a copy of the Exception Report to the
Depositor and the Trustee

The Custodian, on the Trustee's behalf, agrees, for the benefit of
Certificateholders, to review each Mortgage File delivered to it within 270 days
after the Closing Date to ascertain that all documents required by Section 2.01
have been executed and received, and that such documents relate to the Mortgage
Loans identified in Exhibit A that have been conveyed to it. If the Custodian on
the Trustee's behalf finds any document or documents constituting a part of a
Mortgage File to be missing or defective (that is, mutilated, damaged, defaced
or unexecuted) in any material respect, the Custodian on the Trustee's behalf
shall promptly (and in any event within no more than five Business Days) after
such finding so notify the Servicer, the Seller, the Trustee and the Depositor.
In addition, the Custodian on the Trustee's behalf shall also notify the
Servicer, the Seller, the Trustee and the Depositor, if (a) in examining the
Mortgage Files, the documentation shows on its face (i) any adverse claim, lien
or encumbrance, (ii) that any Mortgage Note was overdue or had been dishonored,
(iii) any evidence on the face of any Mortgage Note or Mortgage of any security
interest or other right or interest therein, or (iv) any defense against or
claim to the Mortgage Note by any party or (b) the original Mortgage with
evidence of recording thereon with respect to a Mortgage Loan is not received
within 270 days of the Closing Date; provided, however, that if the Depositor
cannot deliver the original Mortgage with evidence of recording thereon because
of a delay caused by the public recording office where such Mortgage has been
delivered for recordation, the Depositor shall deliver or cause to be delivered
to the Custodian and the Trustee written notice stating that such Mortgage has
been delivered to the appropriate public

49

<PAGE>

recording officer for recordation and thereafter the Depositor shall deliver or
cause to be delivered such Mortgage with evidence of recording thereon upon
receipt thereof from the public recording office. The Depositor shall request
that the Seller correct or cure such omission, defect or other irregularity, or
substitute a Mortgage Loan pursuant to the provisions of Section 3.03, within 60
days from the date the Seller was notified of such omission or defect and, if
the Seller does not correct or cure such omission or defect within such period,
that the Seller purchase such Mortgage Loan from the Trustee within 90 days from
the date the Depositor notified the Seller and the Trustee of such omission,
defect or other irregularity at the Purchase Price of such Mortgage Loan. The
Purchase Price for any Mortgage Loan purchased pursuant to this Section 2.02
shall be paid to the Servicer and deposited by the Servicer in the Collection
Account promptly upon receipt, and, upon receipt by the Trustee of written
notification of such deposit signed by a Servicing Officer, the Trustee shall
promptly release to the Seller the related Mortgage File and the Trustee shall
execute and deliver such instruments of transfer or assignment, without
recourse, as shall be necessary to vest in the Seller or its designee, as the
case may be, any Mortgage Loan released pursuant hereto, and the Trustee shall
have no further responsibility with regard to such Mortgage Loan. It is
understood and agreed that the obligation of the Seller to purchase, cure or
substitute any Mortgage Loan as to which a material defect in or omission of a
constituent document exists shall constitute the sole remedy respecting such
defect or omission available to the Trustee on behalf of Certificateholders. The
Trustee shall be under no duty or obligation to inspect, review and examine such
documents, instruments, certificates or other papers to determine that they are
genuine, enforceable or appropriate to the represented purpose, or that they
have actually been recorded, or that they are other than what they purport to be
on their face. The Trustee shall keep confidential the name of each Mortgagor
and shall not solicit any such Mortgagor for the purpose of refinancing the
related Mortgage Loan.

Within 280 days of the Closing Date, the Trustee based solely on
information provided to it by the Custodian shall deliver to the Depositor and
the Servicer the Trustee's Certification, substantially in the form of Exhibit G
attached hereto, setting forth the status of the Mortgage Files as of such date.

Section 2.03 Trust Fund; Authentication of Certificates. The Trustee
acknowledges and accepts the assignment to it of the Trust Fund created pursuant
to this Agreement in trust for the use and benefit of all present and future
Certificateholders. The Trustee acknowledges the assignment to it for the
benefit of the Trust Fund of the Mortgage Loans and has caused to be
authenticated and delivered to or upon the order of the Depositor, in exchange
for the Mortgage Loans, Certificates and Uncertificated REMIC Interests duly
authenticated by the Trustee or, if an Authenticating Agent has been appointed
pursuant to Section 4.06, the Authenticating Agent in authorized denominations
evidencing ownership of the entire Trust Fund.

Section 2.04 REMIC Elections.

(a) The Depositor hereby instructs and authorizes the Paying Agent to make
appropriate elections to treat the Trust Fund as comprising three REMICs (the
Lower-Tier REMIC, the Middle-Tier REMIC and the Upper-Tier REMIC). This
Agreement shall be construed so as to carry out the intention of the parties
that each REMIC created hereunder be treated as a REMIC at all times prior to
the date on which the Trust Fund is terminated. The Closing Date is hereby
designated as the "startup day" of each REMIC created hereunder within the
meaning of Section 860G(a)(9) of the Code. The Lower-Tier REMIC shall hold as
assets all property of the Trust Fund other than (i) the Lower-Tier REMIC
Interests and the Middle-Tier REMIC Interests and (ii) the Yield Maintenance
Agreements and the Reserve Fund. Each of the Lower-Tier REMIC Regular Interests
is hereby designated a "regular interest" (within the meaning of

50

<PAGE>

Section 860G(a)(1) of the Code) in the Lower-Tier REMIC. The Middle-Tier REMIC
shall hold as assets the several classes of uncertificated Lower-Tier REMIC
Regular Interests. Each of the Middle-Tier REMIC Regular Interests is hereby
designated a "regular interest" (within the meaning of Section 860G(a)(1) of the
Code) in the Middle-Tier REMIC. The Upper-Tier REMIC shall hold as assets the
several classes of uncertificated Middle-Tier REMIC Regular Interests. Each of
the Upper-Tier REMIC Regular Interests is hereby designated as a "regular
interest" (within the meaning of Section 860G(a)(1) of the Code) in the
Upper-Tier REMIC. The Class LT-R Interest is hereby designated as the sole
residual interest (within the meaning of Section 860G(a)(2) of the Code) in the
Lower-Tier REMIC. The Class MT-R Interest is hereby designated as the sole
residual interest (within the meaning of Section 860G(a)(2) of the Code) in the
Middle-Tier REMIC. The Residual Interest is hereby designated as the sole
residual interest (within the meaning of Section 860G(a)(2) of the Code) in the
Upper-Tier REMIC. The Class A-R Certificate evidences ownership of the Class
LT-R Interest, the Class MT-R Interest and the Residual Interest. All interests
described in this Section 2.04(a) shall be designated as such on the Startup
Day.

</TABLE>

-------------

(1) The Class LT-R Interest shall represent the sole class of residual
interest in the Lower-Tier REMIC. The Class LT-R Interest will not have a
principal amount or an interest rate. The Class LT-R Interest shall be
represented by the Class A-R Certificate.

(2) The initial principal amount of the Class LTA-P Interest shall equal the
Original Certificate Principal Balance of the Class A-P Certificates.

(3) The Class LT1A-X Interest is an interest only interest, has no principal
balance, is not entitled to payments of principal and will bear interest
on its notional amount. The notional amount of the Class LT1A-X Interest
shall equal the Class 1-AX Notional Amount.

(4) The Class LT2A-X Interest is an interest only interest, has no principal
balance, is not entitled to payments of principal and will bear interest
on its notional amount. The notional amount of the Class LT2A-X Interest
shall equal the Class 2-AX Notional Amount.

(5) The initial principal amount of the Class LT1-A Interest shall equal 1% of
the Group One Subordinated Amount as of the first Distribution Date.

(6) The initial principal amount of each Lower-Tier REMIC Interest ending with
the designation "B" shall equal the excess of (i) the initial Group One
Non-PO Allocated Amount (in the case of the Class LT1-B Interest) or the
initial Group Two Non-PO Allocated Amount (in the case of the Class LT2-B
Interest) over (ii) the initial principal amount of the Lower-Tier REMIC
Interest ending with the designation "A" that is related to the same
Mortgage Group.

(7) The initial principal amount of the Class LT2-A Interest shall equal 1% of
the Group Two Subordinated Amount as of the first Distribution Date.

Interest shall be payable to, and shortfalls and losses are allocable to,
the Class LT1-AX Interest as such amounts are payable or allocable to the Class
1-AX Certificates. Interest shall be payable to, and shortfalls and losses are
allocable to, the Class LT2-AX Interest as such amounts are payable or allocable
to the Class 2-AX Certificates.

Principal shall be payable to, and shortfalls, losses, prepayments and
increases in principal amount related to Subsequent Recoveries are allocable to,
the Class LTA-P Interest as such amounts are payable or allocable to the Class
A-P Certificates.

After the foregoing allocations and distributions are made to the Class
LT1-AX Interest, Class

52

<PAGE>

LT2-AX Interest and the Class LTA-P Interest, distributions shall be deemed to
be made and Realized Losses shall be deemed to be allocated to the other
Lower-Tier REMIC Regular Interests first, so as to keep the Uncertificated
Principal Balance of each Lower-Tier REMIC Regular Interest ending with the
designation "A" equal to 1% of the excess of (x) the Group One Non-PO Allocated
Amount (in the case of the Class LT1-A Interest) or the Group Two Non-PO
Allocated Amount (in the case of the Class LT2-A Interest) over (y) the
aggregate class principal amounts of the Class 1-A Certificates (in the case of
the Class LT1-A Interest) or the Class 2-A Certificates (in the case of the
Class LT2-A Interest) (except that if 1% of any such excess is greater than the
principal amount of the corresponding Lower-Tier REMIC Regular Interest ending
with the designation "A", the least amount of principal and Realized Losses
shall be distributed and allocated to such Lower-Tier REMIC Regular Interests
such that the Lower-Tier REMIC Subordinated Balance Ratio is maintained); and
second, any remaining principal and Realized Losses to the Lower-Tier REMIC
Regular Interests ending with the designation "B" in such a manner that the
remaining principal balance of each such Lower-Tier REMIC Regular Interest
equals the excess of (x) the Group One Non-PO Allocated Amount (in the case of
the Class LT1-B Interest) or the Group Two Non-PO Allocated Amount (in the case
of the Class LT2-B Interest) over (y) the Uncertificated Principal Balance of
the Lower-Tier REMIC Regular Interest ending with the designation "A" which is
related to the same Mortgage Group. All computations with respect to the
Lower-Tier REMIC Interests shall be taken out to eight decimal places.

If on any Distribution Date there is an increase in the principal amount
of any Class of Certificates (other than the Class A-P Certificates) related to
Subsequent Recoveries, then, prior to distributions of principal and allocations
of losses on such Distribution Date with respect to the Lower-Tier REMIC, there
shall be a corresponding increase in the Uncertificated Principal Balance of the
Lower-Tier REMIC Regular Interests, with such increase allocated among the
Lower-Tier REMIC Regular Interests first, to each Lower-Tier REMIC Regular
Interest ending with the designation "A", so that the Uncertificated Principal
Balance of each such Lower-Tier REMIC Regular Interest continues to equal the
same percentage of the excess of (x) the Group One Non-PO Allocated Amount (in
the case of the Class LT1-A Interest) or the Group Two Non-PO Allocated Amount
(in the case of the Class LT2-A Interest) over (y) the aggregate class principal
amounts of the Class 1-A Certificates (in the case of the Class LT1-A Interest)
or the Class 2-A Certificates (in the case of the Class LT2-A Interest) and so
that the Lower-Tier REMIC Subordinated Balance Ratio is maintained; and second,
any remaining increase allocated to the Lower-Tier REMIC Regular Interests
ending with the designation "B" in such a manner that the principal balance of
each such Lower-Tier REMIC Regular Interest equals the excess of (x) the Group
One Non-PO Allocated Amount (in the case of the Class LT1-B Interest) or the
Group Two Non-PO Allocated Amount (in the case of the Class LT2-B Interest) over
(y) the Uncertificated Principal Balance of the Lower-Tier REMIC Regular
Interest ending with the designation "A" which is related to the same Mortgage
Group.

(b) Solely for the purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
Regulations, the "latest possible maturity date" of each "regular interest" in
each REMIC created hereunder is the Distribution Date immediately following the
latest scheduled maturity of any Mortgage Loan.

(c) The "tax matters person" with respect to each REMIC created hereunder
for purposes of the REMIC Provisions shall be the beneficial owner of the Class
A-R Certificate having the largest Percentage Interest of such Class; provided,
however, that such largest beneficial owner and, to the extent relevant, each
other Holder of a Class A-R Certificate, by its acceptance thereof, irrevocably
appoints the Servicer as its agent and attorney-in-fact to act as "tax matters
person" with respect to each REMIC created hereunder for purposes of the REMIC
provisions.

(d) It is intended that each REMIC created hereunder shall constitute, and
that the affairs of the Trust Fund shall be conducted so as to qualify each
REMIC created hereunder as, a "real estate mortgage investment conduit" as
defined in and in accordance with the REMIC Provisions. In furtherance of such
intention, the Servicer covenants and agrees that it shall act as agent (and the
Servicer is hereby appointed to act as agent) on behalf of the Trust Fund, each
REMIC created hereunder and the Holder of the Class A-R Certificate and that in
such capacity it shall:

(i) prepare and file, or cause to be prepared and filed, in a timely
manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return
(Form 1066) for each REMIC created hereunder and prepare and file or cause

and shall furnish or cause to be furnished to Certificateholders the
schedules, statements or information at such times and in such manner as
may be required thereby;

(ii) within thirty days of the Closing Date, shall furnish or cause
to be furnished to the Internal Revenue Service, on Form 8811 or as
otherwise may be required by the Code, the name, title, address, and
telephone number of the person that the Holders of the Certificates may
contact for tax information relating thereto (and the Servicer shall act
as the representative of the Trust Fund for this purpose), together with
such additional information as may be required by such Form, and shall
update such information at the time or times in the manner required by the
Code;

(iii) make or cause to be made an election, on behalf of each REMIC
created hereunder, to be treated as a REMIC, and make the appropriate
designations, if applicable, in accordance with this Section 2.04 on the
federal tax return of each REMIC hereunder for its first taxable year
(and, if necessary, under applicable state law);

(iv) prepare and forward, or cause to be prepared and forwarded, to
the Certificateholders and to the Internal Revenue Service and, if
necessary, state tax authorities, all information returns or reports, or
furnish or cause to be furnished by telephone, mail, publication or other
appropriate method such information, as and when required to be provided
to them in accordance with the REMIC Provisions, including without
limitation, the calculation of any original issue discount;

(v) provide information necessary for the computation of tax imposed
on the transfer of the Class A-R Certificate to a Disqualified
Organization, or an agent (including a broker,

56

<PAGE>

nominee or other middleman) of a Disqualified Organization, or a
pass-through entity in which a Disqualified Organization is the record
holder of an interest (the reasonable cost of computing and furnishing
such information may be charged to the Person liable for such tax);

returns shall be signed by the Trustee or such other Person as may be
required to sign such returns by the Code or state or local laws,
regulations or rules; and

Trustee, hereby appoints the Global Corporate Trust MBS Group of The Bank of New
York Trust Company, N.A. to perform the duties enumerated in (d) above.

(f) It is intended that the rights of each of the Class 1-A1 and Class
1-A8 Certificates to receive payments in respect of Basis Risk Shortfall
Carryover Amounts shall be treated as a right in interest rate cap contracts and
such shall be accounted for as property held separate and apart from each of the
regular interests in the Upper-Tier REMIC held by the Holders of the Class 1-A1
and Class 1-A8 Certificates, respectively. This provision is intended to satisfy
the requirements of Treasury Regulations Section 1.860G-2(i) for the treatment
of property rights coupled with REMIC interests to be separately respected and
shall be interpreted consistently with such regulation.

REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR AND
THE SERVICER; REPURCHASE OF MORTGAGE LOANS

Section 3.01 Representations and Warranties of the Depositor with respect
to the Mortgage Loans.

The Depositor hereby represents and warrants to the Trustee for the
benefit of the Certificateholders that on or before the Closing Date it has
entered into the Sale Agreement with the Seller, that the Seller has made the
following representations and warranties with respect to each Mortgage Loan in
the Sale Agreement as of the Closing Date, which representations and warranties
run to and are for the benefit of the Depositor and the Trustee for the benefit
of the Certificateholders, and as to which the Depositor has assigned to the
Trustee for the benefit of the Certificateholders, pursuant to Section 2.01
hereof, the right to cause the Seller to repurchase a Mortgage Loan as to which
there has occurred an uncured breach of representations and warranties in
accordance with the provisions of the Sale Agreement.

57

<PAGE>

(a) The information set forth in the Mortgage Loan Schedule is complete,
true and correct in all material respects;

(b) With respect to a Mortgage Loan which is not a Co-op Loan, the
Mortgage creates a first lien or a first priority ownership interest in an
estate in fee simple in real property securing the related Mortgage Note. With
respect to a Co-op Loan, the related Mortgage is a valid, enforceable and
subsisting first security interest on the related cooperative shares securing
the related Mortgage Note, subject only to (a) liens of the related residential
cooperative housing corporation for unpaid assessments representing the
Mortgagor's pro rata share of the related residential cooperative housing
corporation's payments for its blanket mortgage, current and future real
property taxes, insurance premiums, maintenance fees and other assessments to
which like collateral is commonly subject and (b) other matters to which like
collateral is commonly subject which do not materially interfere with the
benefits of the security intended to be provided by the related security
agreement. There are no liens against or security interest in the cooperative
shares relating to each Co-op Loan (except for unpaid maintenance, assessments
and other amounts owed to the related cooperative which individually or in the
aggregate will not have a material adverse effect on such Co-op Loan), which
have priority over the Trustee's security interest in such cooperative shares;

(c) All payments due prior to the Cut-off Date for such Mortgage Loan have
been made as of the Closing Date, the Mortgage Loan is not delinquent in payment
more than 30 days and has not been dishonored; to the best of the Seller's
knowledge, there are no material defaults under the terms of the Mortgage Loan;
the Seller has not advanced funds, or induced, solicited or knowingly received
any advance of funds from a party other than the owner of the Mortgaged Property
subject to the Mortgage (or, with respect to a Co-op Loan, the related
Mortgagor), directly or indirectly, for the payment of any amount required by
the Mortgage Loan; there has been no more than one delinquency in excess of 30
days during the preceding twelve-month period;

(d) To the best of the Seller's knowledge, all taxes, governmental
assessments, insurance premiums, water, sewer and municipal charges, leasehold
payments or ground rents which previously became due and owing have been paid,
or escrow funds have been established in an amount sufficient to pay for every
such escrowed item which remains unpaid and which has been assessed but is not
yet due and payable;

(e) The terms of the Mortgage Note and the Mortgage have not been
impaired, waived, altered or modified in any respect, except by written
instruments. No Mortgagor has been released, in whole or in part, from the terms
thereof except in connection with an assumption agreement and which assumption
agreement is part of the Mortgage File and the terms of which are reflected in
the Mortgage Loan Schedule;

(f)The Mortgage Note and the Mortgage are not subject to any right of
rescission, set-off, counterclaim or defense, including, without limitation, the
defense of usury, nor will the operation of any of the terms of the Mortgage
Note or Mortgage, or the exercise of any right thereunder, render the Mortgage
Note or Mortgage unenforceable, in whole or in part, or subject to any right of
rescission, set-off, counterclaim or defense, including the defense of usury,
and no such right of rescission, set-off, counterclaim or defense has been
asserted with respect thereto, and the Mortgagor was not a debtor in any state
or federal bankruptcy or insolvency proceeding at the time the Mortgage Loan was
originated;

(g) With respect to a Mortgage Loan which is not a Co-op Loan, all
buildings or other customarily insured improvements upon the Mortgaged Property
are insured by an insurer acceptable under the FNMA Guides against loss by fire,
hazards of extended coverage and such other hazards as are provided for in the
FNMA Guides or by FHLMC. All such standard hazard policies are in full force and

58

<PAGE>

effect and on the date of origination contained a standard mortgagee clause
naming the Seller and its successors in interest and assigns as loss payee and
such clause is still in effect and all premiums due thereon have been paid. If
required by the Flood Disaster Protection Act of 1973, as amended, the Mortgaged
Property is covered by a flood insurance policy meeting the requirements of the
current guidelines of the Federal Insurance Administration which policy conforms
to FNMA and FHLMC requirements. The Mortgage obligates the Mortgagor thereunder
to maintain all such insurance at the Mortgagor's cost and expense, and on the
Mortgagor's failure to do so, authorizes the holder of the Mortgage to maintain
such insurance at the Mortgagor's cost and expense and to seek reimbursement
therefor from the Mortgagor;

(h) Any and all requirements of any federal, state or local laws and all
applicable predatory and abusive lending laws, including, without limitation,
usury, truth-in-lending, real estate settlement procedures, consumer credit
protection, equal credit opportunity or disclosure laws applicable to the
Mortgage Loan have been complied with in all material respects;

(i) The Mortgage has not been satisfied, canceled or subordinated, in
whole or in part, or rescinded, and the Mortgaged Property has not been released
from the lien of the Mortgage, in whole or in part nor has any instrument been
executed that would effect any such release, cancellation, subordination or
rescission;

(j) With respect to a Mortgage Loan which is not a Co-op Loan, the
Mortgage is a valid, subsisting, enforceable and perfected first lien on the
Mortgaged Property, including, all buildings on the Mortgaged Property. The
Mortgage and the Mortgage Note do not contain any evidence of any security
interest or other interest or right thereto. Such lien is free and clear of all
adverse claims, liens and encumbrances having priority over the first lien of
the Mortgage subject only to (1) the lien of non-delinquent current real
property taxes and assessments not yet due and payable, (2) covenants,
conditions and restrictions, rights of way, easements and other matters of the
public record as of the date of recording which are acceptable to mortgage
lending institutions generally and either (A) which are referred to or otherwise
considered in the appraisal made for the originator of the Mortgage Loan, or (B)
which do not adversely affect the Appraised Value of the Mortgaged Property as
set forth in such appraisal, and (3) other matters to which like properties are
commonly subject which do not materially interfere with the benefits of the
security intended to be provided by the Mortgage or the use, enjoyment, value or
marketability of the related Mortgaged Property. Any security agreement, chattel
mortgage or equivalent document related to and delivered in connection with the
Mortgage Loan establishes and creates a valid, subsisting, enforceable and
perfected first lien and first priority security interest on the property
described therein, and the Depositor has the full right to sell and assign the
same to the Trustee for the benefit of the Certificateholders;

(k) The Mortgage Note and the related Mortgage are original and genuine
and each is the legal, valid and binding obligation of the maker thereof,
enforceable in all respects in accordance with its terms subject to bankruptcy,
insolvency and other laws of general application affecting the rights of
creditors and the Depositor has taken all action necessary to transfer such
rights of enforceability to the Trustee for the benefit of the
Certificateholders. All parties to the Mortgage Note and the Mortgage had the
legal capacity to enter into the Mortgage Loan and to execute and deliver the
Mortgage Note and the Mortgage. The Mortgage Note and the Mortgage have been
duly and property executed by such parties. The proceeds of the Mortgage Loan
have been fully disbursed and there is no requirement for future advances
thereunder, and any and all requirements as to completion of any on-site or
off-site improvements and as to disbursements of any escrow funds therefor have
been complied with;

(l) The Seller is the sole owner and holder of the Mortgage Loan and the
indebtedness evidenced by the Mortgage Note, except for the Assignments of
Mortgage which have been sent for

59

<PAGE>

recording, and upon recordation the Seller will be the owner of record of the
Mortgage and the indebtedness evidenced by the Mortgage Note, and upon the sale
of the Mortgage Loan to the Trust for the benefit of the Certificateholders, the
Seller will retain the Mortgage File or any part thereof with respect thereto
not delivered to the Trust for the benefit of the Certificateholders or its
designee in trust only for the purpose of servicing and supervising the
servicing of the Mortgage Loan. Immediately prior to the transfer and assignment
to the Trust for the benefit of the Certificateholders, the Mortgage Loan,
including the Mortgage Note and the Mortgage, were not subject to an assignment
or pledge, and the Depositor had good and marketable title to and was the sole
owner thereof and had full right to transfer and sell the Mortgage Loan to the
Trustee for the benefit of the Certificateholders free and clear of any
encumbrance, equity, lien, pledge, charge, claim or security interest and has
the full right and authority subject to no interest or participation of, or
agreement with, any other party, to sell and assign the Mortgage Loan pursuant
to this Agreement and following the sale of the Mortgage Loan, the Trustee for
the benefit of the Certificateholders will own such Mortgage Loan free and clear
of any encumbrance, equity, participation interest, lien, pledge, charge, claim
or security interest;

(m) With respect to a Mortgage Loan which is not a Co-op Loan, the
Mortgage Loan is covered by an ALTA lender's title insurance policy or other
generally acceptable form of policy or insurance acceptable to FNMA or FHLMC,
issued by a title insurer acceptable to FNMA or FHLMC and qualified to do
business in the jurisdiction where the Mortgaged Property is located, insuring
(subject to the exceptions contained in (j) (1), (2) and (3) above) the Seller,
its successors and assigns, as to the first priority lien of the Mortgage in the
original principal amount of the Mortgage Loan. Such lender's title insurance
policy insures ingress and egress by or upon the Mortgaged Property or any
interest therein. Where required by state law or regulation, the Mortgagor has
been given the opportunity to choose the carrier of the required mortgage title
insurance. The Seller, its successors and assigns, are the sole insureds of such
lender's title insurance policy, and such lender's title insurance policy is in
full force and effect and will be in full force and effect upon the consummation
of the transactions contemplated by this Agreement. No claims have been made
under such lender's title insurance policy, and no prior holder of the related
Mortgage, including the Seller, has done, by act or omission, anything which
would impair the coverage of such lender's title insurance policy;

(n) There is no default, breach, violation or event of acceleration
existent, under the Mortgage or the related Mortgage Note and no event which,
with the passage of time or with notice and the expiration of any grace or cure
period, would constitute a default, breach, violation or event permitting
acceleration; and neither the Seller nor any prior mortgagee has waived any
default, breach, violation or event permitting acceleration;

(o) There are no mechanics', or similar liens or claims which have been
filed for work, labor or material (and no rights are outstanding that under law
could give rise to such liens) affecting the related Mortgaged Property (or the
related residential dwelling unit in the Underlying Mortgage Property, in the
case of a Co-op Loan) which are or may be liens prior to or equal to the lien of
the related Mortgage;

(p) With respect to a Mortgage Loan which is not a Co-op Loan, all
improvements subject to the Mortgage which were considered in determining the
Appraised Value of the Mortgaged Property lie wholly within the boundaries and
building restriction lines of the Mortgaged Property (and wholly within the
project with respect to a condominium unit) and no improvements on adjoining
properties encroach upon the Mortgaged Property except those which are insured
against by the title insurance policy referred to in clause (m) above and all
improvements on the property comply with all applicable zoning and subdivision
laws and ordinances; the Mortgaged Property is lawfully occupied under
applicable law;

(q) The Mortgage Loan complies in all material respects with all the
terms, conditions and requirements of the Seller's underwriting standards in
effect at the time of origination of such Mortgage

60

<PAGE>

Loan. The Mortgage Notes and Mortgages (exclusive of any riders) are on forms
generally acceptable to FNMA or FHLMC. Monthly Payments under the Mortgage Note
are due and payable on the first day of each month. The Mortgage contains the
usual and enforceable provisions of the originator at the time of origination
for the acceleration of the payment of the unpaid principal amount of the
Mortgage Loan if the related Mortgaged Property is sold without the prior
consent of the mortgagee thereunder;

(r) The Mortgaged Property (or Underlying Mortgaged Property, in the case
of a Co-op Loan), is not subject to any material damage by waste, fire,
earthquake, windstorm, flood or other casualty. To the best of the Seller's
knowledge, at origination of the Mortgage Loan there was, and there currently
is, no proceeding pending for the total or partial condemnation of the Mortgaged
Property (or Underlying Mortgaged Property, in the case of a Co-op Loan);

(s) The related Mortgage contains customary and enforceable provisions
such as to render the rights and remedies of the holder thereof adequate for the
realization against the Mortgaged Property of the benefits of the security
provided thereby, including, (l) in the case of a Mortgage designated as a deed
of trust, by trustee's sale, and (2) otherwise by judicial foreclosure. There is
no homestead or other exemption available to the Mortgagor which would interfere
with the right to sell the Mortgaged Property at a trustee's sale or the right
to foreclose the Mortgage subject to applicable federal and state laws and
judicial precedent with respect to bankruptcy and right of redemption or similar
law;

(t) If the Mortgage constitutes a deed of trust, a trustee, authorized and
duly qualified if required under applicable law to act as such, has been
properly designated and currently so serves and is named in the Mortgage, and no
fees or expenses, except as may be required by local law, are or will become
payable by the Purchaser to the trustee under the deed of trust, except in
connection with a trustee's sale or attempted sale after default by the
Mortgagor;

(u) The Mortgage File contains an appraisal or a recertification document
(in the case of a Mortgage Loan originated under CHF's Streamlined Refinance
Program) of the related Mortgaged Property (or the related residential dwelling
unit in the Underlying Mortgaged Property, in the case of a Co-op Loan), signed
prior to the final approval of the mortgage loan application by an appraiser
approved by the Seller who had no interest, direct or indirect, in the Mortgaged
Property (or Underlying Mortgaged Property, in the case of a Co-op Loan), or in
any loan made on the security thereof, and whose compensation is not affected by
the approval or disapproval of the Mortgage Loan. The appraisal is in a form
acceptable to FNMA or FHLMC;

(v) All parties which have had any interest in the Mortgage, whether as
mortgagee, assignee, pledgee or otherwise, are (or, during the period in which
they held and disposed of such interest, were) (A) in substantial compliance
with any and all applicable licensing requirements of the laws of the state
wherein the Mortgaged Property (or Underlying Mortgaged Property, in the case of
a Co-op Loan), is located, and (B) (1) organized under the laws of such state,
or (2) qualified to do business in such state, or (3) federal savings and loan
associations or national banks or a Federal Home Loan Bank or savings bank
having principal offices in such state, or (4) not doing business in such state;

(w) The related Mortgage Note is not and has not been secured by any
collateral except the lien of the corresponding Mortgage and the security
interest of any applicable security interest of any applicable agreement or
chattel mortgage referred to above and such collateral does not serve as
security for any other obligation;

(x) The Mortgagor has received all disclosure materials required by
applicable law with respect to the making of such mortgage loans;

61

<PAGE>

(y) The Mortgage Loan does not contain "graduated payment" features;

(z) The Mortgagor is not in bankruptcy and, to the best of the Seller's
knowledge, the Mortgagor is not insolvent;

(aa) The Mortgage Loans are fixed rate mortgage loans. Each Mortgage Loan
has an original term to maturity of not more than thirty (30) years with
interest payable in arrears on the first day of each month. No Mortgage Loan
contains terms or provisions which would result in negative amortization;

(bb) Each Mortgage Note, each Mortgage, each Assignment of Mortgage and
any other documents required pursuant to this Agreement to be delivered to the
Trustee on behalf of the Certificateholders or its designee, or its assignee for
each Mortgage Loan, have been, on or before the Closing Date, delivered to the
Trustee on behalf of the Certificateholders or its designee, or its assignee;

(cc) All escrow payments have been collected in full compliance with state
and federal law and the provisions of the related Mortgage Note and Mortgage. As
to any Mortgage Loan that is the subject of an escrow, escrow of funds is not
prohibited by applicable law and has been established in an amount sufficient to
pay for every escrowed item that remains unpaid and has been assessed but is not
yet due and payable. No escrow deposits or other charges or payments due under
the Mortgage Note have been capitalized under any Mortgage or the related
Mortgage Note. Any interest required to be paid pursuant to state, federal and
local law has been properly paid and credited;

(dd) [Reserved];

(ee) In the event that at origination the Mortgage Loan has a
Loan-to-Value Ratio greater than 80%, the excess of the principal balance of the
Mortgage Loan over 75% of the Appraised Value of the Mortgaged Property, with
respect to a refinanced Mortgage Loan, or the lesser of the Appraised Value or
the purchase price of the Mortgaged Property (or Underlying Mortgaged Property,
in the case of a Co-op Loan), with respect to a purchase money Mortgage Loan, is
and will be insured as to payment defaults by a Primary Insurance Policy issued
by a Qualified Insurer, except where the primary mortgage insurance was (i)
impermissible at origination at applicable law, in which case such Mortgage Loan
was originated in accordance with applicable law, (ii) cancelled at the request
of the Mortgagor pursuant to the cancellation requirements of FNMA, FHLMC, state
law or, as applicable the Home Owner and Equity Protection Act of 1994, as
amended, or (iii) automatically terminated in accordance with the termination
requirements of FNMA, FHLMC, state law or, as applicable the Home Owner and
Equity Protection Act of 1994, as amended. All provisions of such Primary
Insurance Policy have been and are being complied with, such policy is in full
force and effect, and all premiums due thereunder have been paid. No action,
inaction, or event has occurred and no state of facts exists that has, or will
result in the exclusion from, denial of, or defense to coverage. Any Mortgage
Loan subject to a Primary Insurance Policy obligates the Mortgagor thereunder to
maintain the Primary Insurance Policy and to pay all premiums and charges in
connection therewith. The Mortgage Rate for the Mortgage Loan as set forth on
the Mortgage Loan Schedule is net of any such insurance premium;

(ff) The Assignment of Mortgage is in recordable form and is acceptable
for recording (or, in the case of a Co-op Loan, is in a form acceptable for
filing) under the laws of the jurisdiction in which the Mortgaged Property (or
underlying Mortgaged Property, in the case of a Co-op Loan) is located;

(gg) As to Mortgage Loans that are not secured by an interest in a
leasehold estate, the Mortgaged Property (or Underlying Mortgaged Property, in
the case of a Co-op Loan), is located in the state identified in the Mortgage
Loan Schedule and consists of a single parcel of real property with a detached
single family residence erected thereon, or a two-to four-family dwelling, or an
individual

62

<PAGE>


condominium unit in a condominium project, or a dwelling unit in a residential
cooperative housing corporation or an individual unit in an attached planned
unit development or a detached planned unit development, provided, however, that
no residence or dwelling is a single parcel of real property with a mobile home
thereon. As of the date of origination, no portion of the Mortgaged Property (or
Underlying Mortgaged Property, in the case of a Co-op Loan), was used for
commercial purposes, and since the date of origination, to the best of the
Seller's knowledge, no portion of the Mortgaged Property (or Underlying
Mortgaged Property, in the case of a Co-op Loan), is used for commercial
purposes;

(hh) If the Mortgaged Property is a condominium unit or a planned unit
development (other than a de minimis planned unit development), as of the date
of origination of the related Mortgage Loan, such condominium or planned unit
development project met the Seller's eligibility requirements, as set forth in
the Seller's underwriting guidelines as of such date; in the case of each Co-op
Loan, the related residential cooperative housing corporation complied in all
material respects with the Seller's requirements as set forth in the Seller's
underwriting guidelines as of such date;

(ii) To the best of the Seller's knowledge, there is no pending action or
proceeding directly involving the Mortgaged Property (or Underlying Mortgaged
Property, in the case of a Co-op Loan), in which compliance with any
environmental law, rule or regulation is an issue;

(jj) As of the Cut-off Date, the Seller has not granted any interest rate
relief to the Mortgagor under the Relief Act;

(kk) No Mortgage Loan was made in connection with the construction or
rehabilitation of a Mortgaged Property (or Underlying Mortgaged Property, in the
case of a Co-op Loan), or facilitating the trade-in or exchange of a Mortgaged
Property (or Underlying Mortgaged Property, in the case of a Co-op Loan);

(ll) No action has been taken or failed to be taken by Depositor, on or
prior to the Closing Date, which has resulted or will result in an exclusion
from, denial of, or defense to coverage under any Primary Insurance Policy
(including, without limitation, any exclusions, denials or defenses which would
limit or reduce the availability of the timely payment of the full amount of the
loss otherwise due thereunder to the insured) whether arising out of actions,
representations, errors, omissions, negligence, or fraud of the Depositor, or
for any other reason under such coverage;

(mm) The Mortgage Loan was originated by a mortgagee approved by the
Secretary of Housing and Urban Development pursuant to Sections 203 and 211 of
the National Housing Act, as amended, a savings and loan association, a savings
bank, a commercial bank, credit union, insurance company or similar institution
which is supervised and examined by a federal or state authority;

(nn) Principal payments on the Mortgage Loan commenced no more than sixty
(60) days after funds were disbursed in connection with the Mortgage Loan. The
Mortgage Note is payable on the first day of each month in equal monthly
installments of principal and interest, with interest calculated and payable in
arrears, sufficient to amortize the Mortgage Loan fully by the stated maturity
date, over an original term of not more than thirty years from commencement of
amortization;

(oo) As of the Closing Date, the Mortgage Loan is a "qualified mortgage"
within the meaning of Section 860G(a)(3) of the Code (without regard to Treasury
Regulations Section 1.860G-2(f) or any similar rule that provides that a
defective obligation is a qualified mortgage for a temporary period);

63

<PAGE>

(pp) With respect to a Mortgage Loan that is a Co-op Loan, the stock that
is pledged as security for the Mortgage Loan is held by a Person as a
tenant-stockholder (as defined in Section 216 of the Code) in a cooperative
housing corporation (as defined in Section 216 of the Code);

(qq) As of the Closing Date, the Mortgage Loan is not the subject of
pending or final foreclosure proceedings and the Seller would not, based on the
delinquency status of the Mortgage Loan, institute foreclosure proceedings with
respect to the Mortgage Loan prior to the next scheduled payment for the
Mortgage Loan;

(rr) As of the Closing Date, the Mortgage Loan does not provide for
interest other than at either (i) a single fixed rate in effect throughout the
term of the Mortgage Loan or (ii) a "variable rate" (within the meaning of
Treasury Regulation Section 1.860G-1(a)(3)) in effect throughout the term of the
Mortgage Loan;

(ss) No Mortgage Loan is a "covered loan" within the meaning of the
Georgia Fair Lending Act of 2002, as amended;

(tt) None of the Mortgage Loans are (a) covered by the Home Ownership and
Equity Protection Act of 1994 or (b) classified as a "high cost" loan or
similarly classified using different terminology under any federal, state or
local law imposing heightened regulatory scrutiny or additional legal liability
for residential mortgage loans having high interest rates, points and/or fees
such as predatory lending laws; None of the Mortgage Loans are "high cost" loans
as defined by the applicable federal, state or local predatory and abusive
lending laws nor is any Mortgage Loan a "High Cost Loan" or "Covered Loan," as
applicable (as such terms are defined in the current Standard & Poor's LEVELS(R)
Glossary which is now version 5.6 revised, appendix E) and no Mortgage Loan
originated on or after October 1, 2002 through March 6, 2003 is governed by the
Georgia Fair Lending Act of 2002, as amended; and

(uu) As to each Mortgage Loan that is secured by an interest in a
leasehold estate, (i) the use of a leasehold estate for residential properties
is an accepted practice in the area where the related Mortgaged Property is
located, (ii) residential property consisting of leasehold estates is marketable
in the area where the related Mortgaged Property is located, (iii) the related
lease has been recorded in the applicable land records, (iv) the lease is valid
and in good standing and is not subject to any prior lien by which the lease
could be terminated or subject to any charge or penalty, and (v) the remaining
term of the lease does not terminate less than five years after the maturity
date of such Mortgage Loan.

Upon discovery by any of the Depositor, the Servicer or the Trustee of a
breach of any of the foregoing representations and warranties which materially
and adversely affects the value of a Mortgage Loan or the interest of the
Certificateholders (or which materially and adversely affects the interests of
the Certificateholders in the related Mortgage Loan in the case of a
representation and warranty relating to a particular Mortgage Loan), the party
discovering such breach shall give prompt written notice to the other parties
and to the Seller, which notice shall specify the date of discovery. Pursuant to
the Sale Agreement, the Seller shall within 90 days from the earlier of (i) the
date of receipt of notice of such breach or (ii) the date the Seller otherwise
discovers such breach, cure such breach, substitute a Mortgage Loan pursuant to
the provisions of Section 3.03 or, if the breach relates to a particular
Mortgage Loan, purchase such Mortgage Loan from the Trustee at the Purchase
Price. The Purchase Price for the purchased Mortgage Loan shall be paid to the
Servicer and shall be deposited by the Servicer in the Collection Account
promptly upon receipt, and, upon receipt by the Trustee of written notification
of such deposit signed by a Servicing Officer, the Trustee shall promptly
release to the Seller the related Mortgage File, and the Trustee shall execute
and deliver such instruments of transfer or assignment as may be provided to it
by the Servicer, without recourse, as shall be necessary to vest in the Seller
or its

64

<PAGE>

designee, as the case may be, any Mortgage Loan released pursuant hereto, and
the Trustee shall have no further responsibility with regard to such Mortgage
Loan. It is understood and agreed that the obligation of the Seller to cure,
substitute or purchase any Mortgage Loan as to which such a breach has occurred
shall constitute the sole remedy respecting such breach available to
Certificateholders or the Trustee on behalf of Certificateholder.

Section 3.02 Representations and Warranties of the Servicer. The Servicer
represents and warrants to, and covenants with, the Trustee for the benefit of
the Certificateholders that as of the Closing Date:

(a) The Servicer is a limited liability company duly chartered and validly
existing in good standing under the laws of the State of Delaware, and the
Servicer is duly qualified or registered as a foreign corporation in good
standing in each jurisdiction in which the ownership or lease or its properties
or the conduct of its business requires such qualification;

(b) The execution and delivery of this Agreement by the Servicer and its
performance and compliance with the terms of this Agreement will not violate the
Servicer's certificate of formation or by-laws or constitute a default (or an
event which, with notice or lapse of time, or both, would constitute a default)
under, or result in the breach of, any material contract, agreement or other
instrument to which the Servicer is a party or which may be applicable to the
Servicer or any of its assets;

(c) This Agreement, assuming due authorization, execution and delivery by
the Trustee and the Depositor, constitutes a valid, legal and binding obligation
of the Servicer, enforceable against it in accordance with the terms hereof
subject to applicable bankruptcy, insolvency, reorganization, moratorium and
other laws affecting the enforcement of creditors' rights generally and to
general principles of equity, regardless of whether such enforcement is
considered in a proceeding in equity or at law;

(d) The Servicer is not in default with respect to any order or decree of
any court or any order, regulation or demand of any federal, state, municipal or
governmental agency, which default might have consequences that would materially
and adversely affect the condition (financial or other) or operations of the
Servicer or its properties or might have consequences that would affect its
performance hereunder; and

(e) No litigation is pending or, to the best of the Servicer's knowledge,
threatened against the Servicer which would prohibit its entering into this
Agreement or performing its obligations under this Agreement. It is understood
and agreed that the representations and warranties set forth in this Section
3.02 shall survive the issuance and delivery of the Certificates and shall be
continuing as long as any Certificate shall be outstanding or this Agreement has
been terminated.

Section 3.03 Option to Substitute. If the Seller is required to repurchase
any Mortgage Loan pursuant to Section 2.02 or 3.01, the Seller may, at its
option, within two years from the Closing Date, remove such defective Mortgage
Loan from the terms of this Agreement and substitute another mortgage loan for
such defective Mortgage Loan, in lieu of repurchasing such defective Mortgage
Loan. Any substitute Mortgage Loan shall (a) have a Principal Balance at the
time of substitution not in excess of the Principal Balance of the removed
Mortgage Loan (the amount of any difference, plus one month's interest thereon
at the Mortgage Rate borne by the removed Mortgage Loan, being paid by the
Seller and deemed to be a Principal Prepayment to be deposited by the Servicer
in the Collection Account), (b) have a Mortgage Rate not less than, and not more
than one percentage point greater than, the Mortgage Rate of the removed
Mortgage Loan (provided, however, that if the Mortgage Rate on the substitute
Mortgage Loan exceeds the Mortgage Rate on the removed Mortgage Loan, the amount
of that excess interest (the

65

<PAGE>

"Substitute Excess Interest") shall be payable to the Class A-R Certificate),
(c) have a remaining term to stated maturity not later than, and not more than
one year less than, the remaining term to stated maturity of the removed
Mortgage Loan, (d) be, in the reasonable determination of the Servicer, of the
same type, quality and character (including location of the Mortgaged Property
(or underlying Mortgaged Property, in the case of a Co-op Loan)) as the removed
Mortgage Loan as if the breach had not occurred, (e) have a Loan-to-Value Ratio
at origination no greater than that of the removed Mortgage Loan and (f) be, in
the reasonable determination of the Seller, in material compliance with the
representations and warranties contained in the Sale Agreement and described in
Section 3.01, as of the date of substitution.

The Seller shall amend the Mortgage Loan Schedule to reflect the
withdrawal of the removed Mortgage Loan from this Agreement and the substitution
of such substitute Mortgage Loan therefor and shall send a copy of such amended
Mortgage Loan Schedule to the Servicer and the Trustee. The Sale Agreement
provides that upon such amendment the Seller shall be deemed to have made as to
such substitute Mortgage Loan the representations and warranties set forth in
Section 3.01 as of the date of such substitution, which shall be continuing as
long as any Certificate shall be outstanding or this Agreement has not been
terminated, and the remedies for breach of any such representation or warranty
shall be as set forth in Section 3.01. Upon such amendment, the Custodian on
behalf of the Trustee shall review the Mortgage File delivered to it relating to
the substitute Mortgage Loan, within the time and in the manner and with the
remedies specified in Section 2.02, except that for purposes of this Section
3.03 (other than the two-year period specified in the first sentence of this
Section), such time shall be measured from the date of the applicable
substitution. In the event of such a substitution, accrued interest on the
substitute Mortgage Loan for the month in which the substitution occurs and any
Principal Prepayments made thereon during such month shall be the property of
the Trust Fund, and accrued interest for such month on the Mortgage Loan for
which the substitution is made and any Principal Prepayments made thereon during
such month shall be the property of the Seller. The principal payment on a
substitute Mortgage Loan due on the Due Date in the month of substitution shall
be the property of the Seller, and the principal payment on the Mortgage Loan
for which the substitution is made due on such date shall be the property of the
Trust Fund.

(1) The Class 1-A2, Class 1-A9, Class 1-A11, Class 1-A17, Class 1-AX and Class
2-AX Certificates are interest-only certificates, have no principal
balance, are not entitled to payments of principal

68

<PAGE>

and will bear interest on their notional amounts. The initial notional
amounts of the Class 1-A2, Class 1-A9, Class 1-A11, Class 1-A17, Class
1-AX and Class 2-AX Certificates will be $185,000,000, $125,000,
$2,083,333, $16,443,500, $34,248,973 and $3,774,503, respectively.

(2) The Class A-R Certificate represents the residual interest in each of the
REMIC Pools.

(3) The Class A-P Certificates consist of two components. The original
principal amount of Class A-P Component One is $4,389,470.00 and the
original principal amount of Class A-P Component Two is $49,835.00.

(4) Each of these Classes of Certificates is an Exchangeable Initial
Certificate which will not be issued under this Agreement and instead will
be issued pursuant to the Trust Agreement.

(5) Each of these Certificates is an Exchangeable Certificate which will not
be issued under this Agreement and instead will be issued pursuant to the
Trust Agreement. The Original Certificate Principal Balance or notional
amount, as applicable, of each such Class of Certificates will be zero.

The Certificates shall be signed by manual or facsimile signature on
behalf of the Depositor by an officer of the Depositor. Certificates bearing the
manual or facsimile signatures of individuals who were at the time of signature
officers of the Depositor shall bind the Depositor, notwithstanding that such
individuals or any of them have ceased to be an officer prior to the
authentication and delivery of such Certificate or did not hold such offices at
the date of such Certificates. No Certificate shall be entitled to any benefit
under this Agreement, or be valid for any purpose, unless there appears on such
Certificate a manual authentication by an officer of the Trustee (or if an
Authenticating Agent has been appointed pursuant to Section 4.06, the
Authenticating Agent) and such authentication upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication.

Section 4.02 Registration of Transfer and Exchange of Certificates.

(a) The Trustee or, if a Paying Agent has been appointed under Section
4.05, the Paying Agent, shall cause to be kept a certificate register (the
"Certificate Register") in which, subject to such reasonable regulations as it
may prescribe, the Trustee or, if a Paying Agent has been appointed under
Section 4.05, the Paying Agent, shall provide for the registration of
Certificates and of transfers and exchanges of Certificates as herein provided.

(b) Upon surrender for registration of transfer of any Certificate at any
office or agency of the Trustee, or if a Paying Agent has been appointed
hereunder pursuant to Section 4.05, the Paying Agent maintained for such
purpose, the Depositor shall execute and the Trustee or if an Authenticating
Agent is appointed under Section 4.06, the Authenticating Agent shall
authenticate and deliver, in the name of the designated transferee or
transferees, a Certificate of a like Class and aggregate Percentage Interest and
dated the date of authentication by the Authenticating Agent.

(c) No transfer of a Class B-3, Class B-4 or Class B-5 Certificate shall
be made unless such transfer is made pursuant to an effective registration
statement or otherwise in accordance with the requirements under the Securities
Act. If such a transfer is to be made in reliance upon an exemption from said
Act, (i) the Depositor may require (except with respect to the initial transfer
of a Class B-3, Class B-4 or Class B-5 Certificate from J.P. Morgan Securities
Inc. and except if the transferee executes a certificate substantially in the
form of Exhibit H hereto) a written opinion of independent counsel acceptable to
and in form and substance reasonably satisfactory to the Depositor and the
Trustee that such transfer may be made pursuant to an exemption, describing the
applicable exemption and the basis therefor, from said Act and laws or is being
made pursuant to said Act and laws, which opinion of counsel shall not be an
expense of the Trust Fund, the Trustee, the Depositor or the Servicer, and (ii)
the

69

<PAGE>

Depositor shall require the transferee to execute a certification substantially
in the form of Exhibit H or Exhibit I.

(d) (i) No transfer of an ERISA Restricted Certificate or a Class A-R
Certificate shall be made unless the prospective transferee provides the
Depositor and the Trustee with (I) a representation as set forth in Exhibit K
for Class A-R Certificates or in Exhibit M for ERISA Restricted Certificates to
the effect that such transferee is not an employee benefit plan subject to Title
I of ERISA, a plan subject to Section 4975 of the Code or a plan or arrangement
subject to any provisions under any federal, state, local, non-U.S. or other
laws or regulations that are substantively similar to the foregoing provisions
of ERISA or the Code ("Similar Law") (collectively, a "Plan"), and is not
directly or indirectly acquiring the Certificate for, on behalf of or with any
assets of any such Plan, or (II) solely in the case of an ERISA Restricted
Certificate, (A) if the Certificate has been the subject of an ERISA-Qualifying
Underwriting, a representation as set forth in Exhibit M that such transferee is
an insurance company that is acquiring the ERISA-Restricted Certificate with
assets contained in an "insurance company general account," as defined in
Section V(E) of Prohibited Transaction Class Exemption ("PTCE") 95-60, and the
acquisition and holding of the Certificate are covered and exempt under Sections
I and III of PTCE 95-60, or (B) solely in the case of a Definitive Certificate,
an Opinion of Counsel reasonably satisfactory to the Depositor and the Trustee
to the effect that the acquisition and holding of such Certificate will not
constitute or result in a nonexempt prohibited transaction under ERISA or the
Code, or a violation of Similar Law, and will not subject the Depositor, the
Servicer or the Trustee to any obligation in addition to those expressly
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Depositor, the Servicer or the Trustee.

(ii) Except in the case of a Definitive Certificate, the
representations set forth in paragraph (i) of this Subsection 4.02(d), other
than subparagraph (i)(II)(B), shall be deemed to have been made to the Depositor
and the Trustee by the transferee's acceptance of an ERISA Restricted
Certificate or a Class A-R Certificate (or the acceptance by a Certificate Owner
of the beneficial interest in any Class of ERISA Restricted Certificates or a
Class A-R Certificate). Notwithstanding any other provision herein to the
contrary, any purported transfer of an ERISA Restricted Certificate or a Class
A-R Certificate to or on behalf of a Plan without the delivery to the Depositor
of a representation or an Opinion of Counsel reasonably satisfactory to the
Depositor and the Trustee as described above shall be void and of no effect.
None of the Depositor, the Servicer or the Trustee shall be under any liability
to any Person for any registration or transfer of any ERISA Restricted
Certificate or Class A-R Certificate that is in fact not permitted by this
Section 4.02(d) nor shall the Paying Agent be under any liability for making any
payments due on such Certificate to the Holder thereof or taking any other
action with respect to such Holder under the provisions of this Agreement so
long as the transfer was registered in accordance with the foregoing
requirements. The Depositor, Servicer, Paying Agent and/or Trustee shall be
entitled, but not obligated, to recover from any Holder of any ERISA Restricted
Certificate or Class A-R Certificate that was in fact a Plan and that held such
Certificate in violation of this Section 4.02(d) all payments made on such ERISA
Restricted Certificate or Class A-R Certificate at and after the time it
commenced such holding. Any such payments so recovered shall be paid and
delivered to the last preceding Holder of such Certificate that is not a Plan.

(e) At the option of a Certificateholder, a Certificate may be exchanged
for another Certificate or Certificates of authorized denominations of a like
Class, upon surrender of the Certificate to be exchanged at any office or agency
of the Trustee, or if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, maintained for such purpose. Whenever the Certificate is so
surrendered for exchange, the Depositor shall execute and the Authenticating
Agent shall authenticate and deliver, the Certificate which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer or exchange shall (if so required by the
Authenticating Agent) be

70

<PAGE>

duly endorsed by, or be accompanied by a written instrument of transfer in the
form satisfactory to the Authenticating Agent duly executed by, the Holder
thereof or his attorney duly authorized in writing.

(f) No service charge shall be made to the Holder for any transfer or
exchange of a Certificate, but the Servicer may require payment by the
Certificateholders of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any transfer or exchange of such
Certificate.

(g) All Certificates surrendered for transfer or exchange shall be
destroyed by the Trustee or if a Paying Agent has been appointed under Section
4.05, the Paying Agent, in accordance with the Trustee's or, if a Paying Agent
has been appointed under Section 4.05, the Paying Agent's, standard procedures.

(h) [Reserved].

(i) A Disqualified Organization is prohibited from acquiring beneficial
ownership of a Class A-R Certificate. Notwithstanding anything to the contrary
contained herein, (i) unless and until the Servicer and the Trustee shall have
received an Opinion of Counsel, satisfactory to it in form and substance, to the
effect that the absence of the conditions contained in this Section 4.02(i)
would not result in the imposition of federal tax upon any REMIC created
hereunder or cause any REMIC created hereunder to fail to qualify as a REMIC, no
transfer, sale or other disposition of the Class A-R Certificate (including for
purposes of this section any beneficial interest therein) may be made without
the express written consent of the Certificate Registrar or, if no Certificate
Registrar is appointed, the Trustee, which consent is to be granted by the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee
only upon compliance with the requirements of this Section and (ii) no transfer,
sale or other disposition of the Class A-R Certificate (or any beneficial
interest therein) may be made to a Person who is not a U.S. Person unless such
Person furnishes the transferor, the Certificate Registrar and the Trustee, with
a duly completed and effective Form W-8ECI (or any successor thereto) or an
Opinion of Counsel to the effect that such transfer is in accordance with the
requirements of the Code and that the transfer will not be disregarded for
federal income tax purposes. As a condition to granting its consent to a
transfer of a Class A-R Certificate, the Certificate Registrar or, if no
Certificate Registrar is appointed, the Trustee, shall require the proposed
transferee of such Certificate (including, in the case of the initial issuance
of the Class A-R Certificate, the initial Holder thereof) to execute a letter
and affidavit substantially in the form attached hereto as Exhibit K and shall
require the proposed transferor (other than in the case of the transfer to the
initial Holder) of such Certificate to execute a letter substantially in the
form attached hereto as Exhibit K-1. In the absence of a contrary instruction
from the transferor of such Certificate, declaration (11) in the affidavit in
Exhibit K may be left blank. If the transferor requests by written notice to the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee,
prior to the date of the proposed transfer that one of the two other forms of
declaration (11) of such affidavit be used, then the Certificate Registrar or,
if no Certificate Registrar is appointed, the Trustee, shall require that such
form of declaration (11) be included in such affidavit.

As a condition to the granting of the consent referred to in this Section
4.02(i), prior to the transfer, sale, pledge, hypothecation or other disposition
of the Class A-R Certificate or any interest therein, the Certificate Registrar
or, if no Certificate Registrar is appointed, the Trustee shall require that (1)
the proposed transferee deliver to the Trustee or Certificate Registrar, as
applicable, its taxpayer identification number and state, under penalties of
perjury that such number is the social security or employer identification
number, as the case may be, of the transferee or provide an affidavit under
penalties of perjury stating that as of the date of such transfer such
transferee is not and has no intention of becoming a Disqualified Organization;
(2) the proposed transferee deliver to the Trustee or Certificate Registrar, as
applicable, an affidavit stating (i) that such transferee is not acquiring such
Class A-R

71

<PAGE>

Certificate as an agent, broker, nominee, or middleman for a Disqualified
Organization, (ii) if the Class A-R Certificate is a "non-economic residual
interest" within the meaning of Treas. Reg. Section 1.860E-1(c)(2), (X) that no
purpose of the acquisition of the Class A-R Certificate is to avoid or impede
the assessment or collection of tax, (Y) that such transferee has historically
paid its debts as they came due and will continue to pay its debts as they come
due, and (Z) that such transferee represents that it understands that, as the
holder of the non-economic residual interest, the transferee may incur tax
liabilities in excess of any cash flows generated by the interest and that the
transferee intends to pay taxes associated with holding the residual interest,
and (iii) unless the Certificate Registrar or, if no Certificate Registrar is
appointed, the Trustee consents to the transfer of the Class A-R Certificate to
a Person who is not a U.S. Person and who has furnished either a duly completed
and effective Form W-8ECI (or any successor thereto) or an Opinion of Counsel to
the effect that the transfer will not be disregarded for federal income tax
purposes, that it is a U.S. Person; (3) if so requested by the transferor in
written notice provided to the Certificate Registrar or, if no Certificate
Registrar is appointed, the Trustee, prior to the date of the proposed transfer,
the proposed transferee deliver to the Trustee or Certificate Registrar, as
applicable, an affidavit that includes a declaration made in the form of
declaration (11) in the affidavit set forth in Exhibit K requested by the
transferor; and (4) the transferor deliver to the Certificate Registrar or, if
no Certificate Registrar is appointed, the Trustee a written certification that
as of the date of such transfer it has no knowledge and no reason to know that
the affirmations described in clauses (1), (2) and (3) were false. The
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee
shall not grant the consent referred to in this Section 4.02(i) if it has actual
knowledge that any statement made in the affidavit issued pursuant to the
preceding sentence is not true. Notwithstanding any purported transfer, sale or
other disposition of the Class A-R Certificate to a Disqualified Organization or
in violation of the provisions of this Section 4.02(i), such transfer, sale or
other disposition shall be deemed to be of no legal force or effect whatsoever
and such Disqualified Organization shall not be deemed to be a Class A-R
Certificateholder for any purpose hereunder, including, but not limited to, the
receipt of distributions on such Class A-R Certificate. If any purported
transfer shall be in violation of the provisions of this Section 4.02(i) then
the prior Holder of the Class A-R Certificate shall, upon discovery that the
transfer of such Class A-R Certificate was not in fact permitted by this Section
4.02(i), be restored to all rights and obligations as a Holder thereof
retroactive to the date of the purported transfer of such Class A-R Certificate.
The Trustee, the Servicer and the Certificate Registrar shall be under no
liability to any Person for any registration or transfer of a Class A-R
Certificate that is not permitted by this Section 4.02(i) or for making payments
due on such Class A-R Certificate to the purported Holder thereof or taking any
other action with respect to such purported Holder under the provisions of this
Agreement so long as the transfer was not registered under the written
certification of the Certificate Registrar or, if no Certificate Registrar is
appointed, the Trustee as described in this Section 4.02(i). The prior Holder
shall be entitled to recover from any purported Holder of a Class A-R
Certificate that was in fact not a permitted purported transferee under this
Section 4.02(i) at the time it became a purported Holder all payments made to
such purported Holder on such Class A-R Certificate; provided that the Servicer
shall not be responsible for such recovery. Each Class A-R Certificateholder, by
the acceptance of the Class A-R Certificate, shall be deemed for all purposes to
have consented to the provisions of this Section 4.02(i) and to any amendment to
this Agreement deemed necessary by counsel of the Trustee or the Servicer to
ensure that the Class A-R Certificate is not transferred to a Disqualified
Organization and that any transfer of such Class A-R Certificate will not cause
the imposition of a tax upon any REMIC created hereunder or cause any REMIC
created hereunder to fail to qualify as a REMIC. The restrictions on transfer of
the Class A-R Certificate will cease to apply and be void upon receipt by the
Certificate Registrar or, if no Certificate Registrar is appointed, the Trustee
of an Opinion of Counsel to the effect that such restrictions on transfer are no
longer necessary to avoid the risk of material federal taxation to any REMIC
created hereunder or prevent any REMIC created hereunder from qualifying as a
REMIC.

72

<PAGE>

(j) The Servicer shall make available upon written request to each Holder
and each proposed transferee of a Class B-4, Class B-5 or Class B-6 Certificate
such information as may be required to permit the proposed transfer to be
effected pursuant to Rule 144A under the Securities Act.

Section 4.03 Mutilated, Destroyed, Lost or Stolen Certificates. If (a) any
mutilated Certificate is surrendered to the Trustee or, if a Paying Agent has
been appointed under Section 4.05, the Paying Agent, or the Trustee or, if a
Paying Agent has been appointed under Section 4.05, the Paying Agent, receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (b) there is delivered to the Trustee or, if a Paying Agent has
been appointed under Section 4.05, the Paying Agent, such security or indemnity
as may be required by it to save it harmless, then, in the absence of notice to
the Trustee or, if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, that such Certificate has been acquired by a bona fide purchaser,
the Trustee or, if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, shall authenticate and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Class. Upon the issuance of any new Certificate under this Section,
the Trustee or, if a Paying Agent has been appointed under Section 4.05, the
Paying Agent, may require of the Certificateholder the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses connected therewith. Any replacement
Certificate of any Class issued pursuant to this Section shall constitute
complete and indefeasible evidence of ownership of the Percentage Interest in
the distributions to which the Certificateholders of such Class are entitled, as
if originally issued, whether or not the mutilated, destroyed, lost or stolen
Certificate shall be found at any time, and such mutilated, destroyed, lost or
stolen Certificate shall be of no force or effect under this Agreement, to the
extent permitted by law.

Section 4.04 Persons Deemed Owners. Prior to due presentation of a
Certificate of any Class for registration of transfer, the Depositor, the
Servicer, the Paying Agent and the Trustee may treat the Person in whose name
any Certificate is registered on the Record Date as the owner of such
Certificate and the Percentage Interest in the distributions to which the
Certificateholders of such Class are entitled on the relevant date as the Holder
of such Certificate and the Percentage Interest represented by such Certificate
for the purpose of receiving remittances pursuant to Section 6.01 and for all
other purposes whatsoever, and neither the Depositor, the Servicer, the Paying
Agent nor the Trustee shall be affected by notice to the contrary.

Section 4.05 Appointment of Paying Agent and Certificate Registrar;
Certificate Account. The Trustee shall appoint a Paying Agent and a Certificate
Registrar (the "Certificate Registrar") hereunder, provided such Paying Agent
and such Certificate Registrar shall not be the Depositor, any Seller, or an
Affiliate of the Depositor or any Seller. No later than two Business Days prior
to each Distribution Date, the Servicer shall deposit or cause to be deposited
with the Paying Agent from funds on deposit in the Collection Account a sum up
to the Available Distribution Amount, such sum to be held in trust for the
benefit of Certificateholders in a segregated account (the "Certificate
Account") which shall be an Eligible Account in the name of "The Bank of New
York Trust Company, N.A., as Trustee, in trust for and for the benefit of the
Certificateholders of Multi-Class Mortgage Pass-Through Certificates, Chase
Mortgage Finance Corporation, Series 2007-S3 - Certificate Account". The Paying
Agent shall establish such Certificate Account with a commercial bank, a savings
bank or a savings and loan association. The Paying Agent may invest moneys in
the Certificate Account in Eligible Investments, which shall mature not later
than a date sufficient to make payment on the Distribution Date next following
the date of such investment and shall not be sold or disposed of prior to
maturity. All income and gain realized from any such investment shall be for the
benefit of the Paying Agent as additional compensation and shall be subject to
its withdrawal or order from time to time. The amount of any losses incurred in
respect of any such investments (to the extent not offset by income from other
such investments) shall be deposited in the Certificate Account by the Paying
Agent out of its own funds

73

<PAGE>

immediately as realized. The Servicer shall cause the Paying Agent to perform
each of the obligations of the Paying Agent set forth herein and shall be liable
to the Trustee and the Certificateholders for failure of the Paying Agent to
perform such obligations. So long as the Paying Agent is a party other than the
Trustee, the Trustee shall have no liability in connection with the performance
or failure of performance of the Paying Agent. The Trustee designates The Bank
of New York Trust Company, N.A. as the initial Paying Agent and initial
Certificate Registrar. Only the Trustee may remove the Paying Agent and
Certificate Registrar and may do so at will, provided that the Trustee gives 20
days' prior written notice of such removal to the Paying Agent and Certificate
Registrar and the Rating Agencies.

The Paying Agent will hold all sums held by it for the payment to
Certificateholders in trust for the benefit of the Certificateholders entitled
thereto until such sums shall be paid to such Certificateholders.

Section 4.06 Authenticating Agents.

(a) The Trustee may appoint one or more Authenticating Agents (each, an
"Authenticating Agent") which shall be authorized to act on behalf of the
Trustee in authenticating the Certificates. Wherever reference is made in this
Agreement to the authentication of Certificates by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication on behalf of the Trustee by an Authenticating Agent and a
certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent. Each Authenticating Agent must be an entity organized and
doing business under the laws of the United States of America or of any state,
having a combined capital and surplus of at least $15,000,000, authorized under
such laws to do a trust business and subject to supervision or examination by
federal or state authorities. So long as the Authenticating Agent is a party
other than the Trustee, the Trustee shall have no liability in connection with
the performance or failure of performance of the Authenticating Agent. The
Trustee hereby appoints the Paying Agent as the initial Authenticating Agent.

(b) Any Person into which any Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from any
merger, conversion or consolidation to which any Authenticating Agent shall be a
party, or any Person succeeding to the corporate agency business of any
Authenticating Agent, shall continue to be the Authenticating Agent without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

(c) Any Authenticating Agent may at any time resign by giving at least 30
days' advance written notice of resignation to the Trustee and the Depositor.
The Trustee may at any time terminate the agency of any Authenticating Agent by
giving written notice of termination to such Authenticating Agent and the
Depositor. Upon receiving a notice of resignation or upon such a termination, or
in case at any time any Authenticating Agent shall cease to be eligible in
accordance within the provisions of this Section 4.06, the Trustee may appoint a
successor Authenticating Agent, shall give written notice of such appointment to
the Depositor and shall mail notice of such appointment to all Holders of
Certificates. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall
