     Section 2.01 FORM. The Class A, Class M and Class B Bonds, together with
the Indenture Trustee's certificate of authentication, shall be in substantially
the form set forth in Exhibits A-1, A-2 and A-3 to this Indenture, respectively,
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture.

     The Bonds shall be typewritten, printed, lithographed or engraved or
produced by any combination of these methods (with or without steel engraved
borders).

     The terms of the Bonds set forth in Exhibits A-1, A-2 and A-3 to this
Indenture are part of the terms of this Indenture.

     Section 2.02 EXECUTION, AUTHENTICATION AND DELIVERY. The Bonds shall be
executed on behalf of the Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Bonds may be manual or
facsimile.

     Bonds bearing the manual or facsimile signature of individuals who were at
any time Authorized Officers of the Issuer shall bind the Issuer,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Bonds or did not hold
such offices at the date of such Bonds.

     The Indenture Trustee shall upon Issuer Request authenticate and deliver
the Class 1-A-1, Class 2-A-1, Class 3-A-1, Class 3-M-1, Class 3-M-2, Class 1-B-1

be issued in an aggregate initial principal amount of $259,500,000, the Class
3-M-1 Bonds shall be issued in an aggregate initial principal amount of

initial principal amount of $14,850,000 and the Class 3-B-1 Bonds shall be
issued in an aggregate initial principal amount of $5,250,000.

     The Class 3-A-IO Bonds will not have a Bond Principal Balance and will not

interest on the related Notional Amount. For the April 2003 Payment Date through
the March 2004 Payment Date, the Notional Amount of the Class 3-A-IO Bonds will
be $37,500,695, for the April 2004 Payment Date through the September 2004

minimum initial Bond Principal Balances of $25,000 and in integral multiples of
$1 in excess thereof.


                                        4

     No Bond shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Bond a certificate
of authentication substantially in the form provided for herein executed by the
Indenture Trustee by the manual signature of one of its authorized signatories,
and such certificate upon any Bond shall be conclusive evidence, and the only
evidence, that such Bond has been duly authenticated and delivered hereunder.

     Section 2.03 ACCEPTANCE OF MORTGAGE LOANS BY INDENTURE TRUSTEE. (a) The
Indenture Trustee acknowledges receipt of, subject to the exceptions it notes
pursuant to the procedures described below, the documents (or certified copies
thereof) referred to in Section 2.1(b) of the Mortgage Loan Sale and
Contribution Agreement, and declares that it holds and will continue to hold
those documents and any amendments, replacements or supplements thereto and all
other assets of the Trust Estate as Indenture Trustee in trust for the use and
benefit of all present and future Holders of the Bonds and the Bond Insurer. No
later than 45 days after the Closing Date, with respect to the Initial Mortgage
Loans, or the applicable Subsequent Transfer Date, with respect to the related
Group 1 Subsequent Mortgage Loans (or, with respect to any Eligible Substitute
Mortgage Loan, within 5 days after the receipt by the Indenture Trustee thereof
and, with respect to any documents received beyond 45 days after the Closing
Date or Subsequent Transfer Date, as applicable, promptly thereafter), the
Indenture Trustee agrees, for the benefit of the Bondholders and the Bond
Insurer, to review each Mortgage File delivered to it and to execute and
deliver, or cause to be executed and delivered, to the Seller, the Bond Insurer
and the Master Servicer an Initial Certification in the form annexed hereto as
Exhibit C. In conducting such review, the Indenture Trustee will ascertain
whether all required documents described in Section 2.1(b) of (i) the Mortgage
Loan Sale and Contribution Agreement, with respect to the Initial Mortgage
Loans, and (ii) the applicable Subsequent Mortgage Loan Sale and Contribution
Agreements, with respect to the related Group 1 Subsequent Mortgage Loans, have
been executed and received and whether those documents relate, determined on the
basis of the Mortgagor name, original principal balance and loan number, to the
Mortgage Loans it has received, as identified in Exhibit B to this Indenture, as
supplemented (PROVIDED, HOWEVER, that with respect to those documents described
in subclause (b)(vii) of such section, the Indenture Trustee's obligations shall
extend only to documents actually delivered pursuant to such subclause). In
performing any such review, the Indenture Trustee may conclusively rely on the
purported due execution and genuineness of any such document and on the
purported genuineness of any signature thereon. If the Indenture Trustee finds
any document constituting part of the Mortgage File not to have been executed or
received, or to be unrelated to the Mortgage Loans identified in Exhibit B to
this Indenture or to appear to be defective on its face, the Indenture Trustee
shall promptly notify the Seller and the Bond Insurer of such finding and the
Seller's obligation to cure such defect or repurchase or substitute for the
related Mortgage Loan. To the extent the Indenture Trustee has not received a
Mortgage File with respect to any of the Initial Mortgage Loans by the Closing
Date, or any of the related Group 1 Subsequent Mortgage Loans by the applicable
Subsequent Transfer Date, the Indenture Trustee shall not require the deposit of

                                    Covenants

     Section 3.01 COLLECTION OF PAYMENTS WITH RESPECT TO THE MORTGAGE LOANS. The
Indenture Trustee shall establish and maintain an Eligible Account (the "Payment
Account") in which the Indenture Trustee shall, subject to the terms of this
paragraph, deposit, on the same day as it is received from the Master Servicer,
each remittance received by the Indenture Trustee with respect to the Mortgage

Bonds may be surrendered for registration of transfer or exchange, and where
notices and demands to or upon the Issuer in respect of the Bonds and this

Trustee to serve as its agent for the foregoing purposes. If at any time the
Issuer shall fail to maintain any such office or agency or shall fail to furnish
the Indenture Trustee with the address thereof, such surrenders may be made at
the office of the Indenture Trustee located at c/o DTC Transfer Services, 55
Water Street, Jeanette Park Entrance, New York, New York 10041, and notices and
demands may be made or served at the Corporate Trust Office, and the Issuer
hereby appoints the Indenture Trustee as its agent to receive all such
surrenders, notices and demands.

     Section 3.03 MONEY FOR PAYMENTS TO BE HELD IN TRUST; PAYING AGENT. (a) As
provided in Section 3.01, all payments of amounts due and payable with respect
to any Bonds that are to be made from amounts withdrawn from the Payment Account
pursuant to Section 3.01 shall be made on behalf of the Issuer by the Indenture
Trustee or by the Paying Agent, and no amounts so withdrawn from the Payment
Account for payments of Bonds shall be paid over to the Issuer except as
provided in this Section 3.03. The Issuer hereby appoints the Indenture Trustee
as its Paying Agent.

     The Issuer will cause each Paying Agent other than the Indenture Trustee to
execute and deliver to the Indenture Trustee an instrument in which such Paying
Agent shall agree with the Indenture Trustee (and if the Indenture Trustee acts
as Paying Agent it hereby so agrees), subject to the provisions of this Section
3.03, that such Paying Agent will:

               (i) hold all sums held by it for the payment of amounts due with
     respect to the Bonds in trust for the benefit of the Persons entitled
     thereto until such sums shall be paid to such Persons or otherwise disposed
     of as herein provided and pay such sums to such Persons as herein provided;

               (ii) give the Indenture Trustee and the Bond Insurer notice of
     any default by the Issuer of which it has actual knowledge in the making of
     any payment required to be made with respect to the Bonds;

<PAGE>



               (iii) at any time during the continuance of any such default,
     upon the written request of the Indenture Trustee, forthwith pay to the
     Indenture Trustee all sums so held in trust by such Paying Agent;

               (iv) immediately resign as Paying Agent and forthwith pay to the
     Indenture Trustee all sums held by it in trust for the payment of Bonds if
     at any time it ceases to meet the standards required to be met by a Paying
     Agent at the time of its appointment;

               (v) comply with all requirements of the Code with respect to the
     withholding from any payments made by it on any Bonds of any applicable
     withholding taxes imposed thereon and with respect to any applicable
     reporting requirements in connection therewith; and

               (vi) not commence a bankruptcy proceeding against the Issuer in
     connection with this Indenture.

     The Issuer may at any time, for the purpose of obtaining the satisfaction
and discharge of this Indenture or for any other purpose, by Issuer Request
direct any Paying Agent to pay to the Indenture Trustee all sums held in trust
by such Paying Agent, such sums to be held by the Indenture Trustee upon the
same trusts as those upon which the sums were held by such Paying Agent; and
upon such payment by any Paying Agent to the Indenture Trustee, such Paying
Agent shall be released from all further liability with respect to such money.

     Subject to applicable laws with respect to escheat of funds, any money held
by the Indenture Trustee or any Paying Agent in trust for the payment of any
amount due with respect to any Bond (other than amounts paid under the Bond
Insurance Policy) and remaining unclaimed for one year after such amount has
become due and payable shall be discharged from such trust and be paid to the
Issuer on Issuer Request; and the Holder of such Bond shall thereafter, as an
unsecured general creditor, look only to the Issuer for payment thereof (but
only to the extent of the amounts so paid to the Issuer), and all liability of
the Indenture Trustee or such Paying Agent with respect to such trust money
shall thereupon cease; PROVIDED, HOWEVER, that the Indenture Trustee or such
Paying Agent, before being required to make any such repayment, shall at the
expense and direction of the Issuer cause to be published once, in an Authorized
Newspaper published in the English language, notice that such money remains
unclaimed and that, after a date specified therein which shall not be less than
30 days from the date of such publication, any unclaimed balance of such money
then remaining will be repaid to the Issuer. The Indenture Trustee, with the
written consent of the Bond Insurer, so long as no Bond Insurer Default exists,
may also adopt and employ, at the expense and direction of the Issuer, any other
reasonable means of notification of such repayment (including, but not limited
to, mailing notice of such repayment to Holders whose Bonds have been called but
have not been surrendered for redemption or whose right to or interest in monies
due and payable but not claimed is determinable from the records of the
Indenture Trustee or of any Paying Agent, at the last address of record for each
such Holder).

rights and franchises as a statutory trust under the laws of the State of
Delaware (unless it becomes, or any successor Issuer hereunder is or becomes,
organized under the laws of any other state or of the

     section 1.1001-3, or adversely affect the status of the Bonds as

of the Group 1 Loans is less than the aggregate Bond Principal Balances of the
Class 1-A-1 Bonds and Class 1-B-1 Bonds due to Realized Losses on the Group 1
Loans, the Bond Principal Balances of the Class 1-B-1 Bonds shall be reduced,
until the Bond Principal Balance thereof has been reduced to zero. Any further
losses will be covered by the Bond Insurance Policy in accordance with the terms
thereof, however, to the extent such Realized Losses are not covered by the Bond
Insurance Policy, the Bond Principal Balance of the Class 1-A-1 Bonds will not
be reduced by the amount of such Realized Losses. On each Payment Date following

Policy in accordance with the terms thereof, however, to the extent such
Realized Losses are not covered by the Bond Insurance Policy, the Bond Principal
Balance of the Class 2-A-1 Bonds will not be reduced by the amount of such
Realized Losses. On each Payment Date following the application of all amounts
distributable on such date, to the extent the aggregate Stated Principal Balance

Realized Losses on the Group 3 Loans, the Bond Principal Balances of the Class
3-B-1 Bonds, Class 3-M-2 Bonds and Class 3-M-1 Bonds shall be reduced
sequentially, in that order, until the respective Bond Principal Balance thereof
has been reduced to zero. All Realized Losses allocated to a Class of Bonds will

                                   ARTICLE IV

               The Bonds; Satisfaction and Discharge of Indenture

     Section 4.01 THE BONDS. Each Class of Bonds shall be registered in the name
of a nominee designated by the Depository. Beneficial Owners will hold interests
in the Bonds through the book- entry facilities of the Depository in minimum
initial Bond Principal Balances of $25,000 and integral multiples of $1 in
excess thereof.

     The Indenture Trustee may for all purposes (including the making of
payments due on the Bonds) deal with the Depository as the authorized
representative of the Beneficial Owners with respect to the Bonds for the
purposes of exercising the rights of Holders of the Bonds hereunder. Except as
provided in the next succeeding paragraph of this Section 4.01, the rights of
Beneficial Owners with respect to the Bonds shall be limited to those
established by law and agreements between such Beneficial Owners and the
Depository and Depository Participants. Except as provided in Section 4.08
hereof, Beneficial Owners shall not be entitled to definitive certificates for
the Bonds as to which they are the Beneficial Owners. Requests and directions
from, and votes of, the Depository as Holder of the Bonds shall not be deemed
inconsistent if they are made with respect to different Beneficial Owners. The
Indenture Trustee may establish a reasonable record date in connection with
solicitations of consents from or voting by Bondholders and give notice to the
Depository of such record date. Without the consent of the Issuer and the
Indenture Trustee, no Bond may be transferred by the Depository except to a
successor Depository that agrees to hold such Bond for the account of the
Beneficial Owners.

     In the event the Depository Trust Company resigns or is removed as
Depository, the Indenture Trustee with the approval of the Issuer may appoint a
successor Depository. If no successor Depository has been appointed within 30
days of the effective date of the Depository's resignation or removal, each
Beneficial Owner shall be entitled to certificates representing the Bonds it
beneficially owns in the manner prescribed in Section 4.08.

     The Bonds shall, on original issue, be executed on behalf of the Issuer by
the Owner Trustee, not in its individual capacity but solely as Owner Trustee,
authenticated by the Indenture Trustee and delivered by the Indenture Trustee to
or upon the order of the Issuer.

     Section 4.02 REGISTRATION OF AND LIMITATIONS ON TRANSFER AND EXCHANGE OF
BONDS; APPOINTMENT OF BOND REGISTRAR AND CERTIFICATE REGISTRAR. The Issuer shall
cause to be kept at the Corporate Trust Office a Bond Register in which, subject
to such reasonable regulations as it may prescribe, the Bond Registrar shall
provide for the registration of Bonds and of transfers and exchanges of Bonds as
herein provided.

     Subject to the restrictions and limitations set forth below, upon surrender
for registration of transfer of any Bond at the Corporate Trust Office, the
Issuer shall execute and the Bond Registrar shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new Bonds in
authorized initial Bond Principal Balances evidencing the same Class and
aggregate Percentage Interests.



                                       31

<PAGE>



     Subject to the foregoing, at the option of the Bondholders, Bonds may be
exchanged for other Bonds of like tenor and in authorized initial Bond Principal
Balances evidencing the same Class and aggregate Percentage Interests upon
surrender of the Bonds to be exchanged at the Corporate Trust Office of the Bond
Registrar. Whenever any Bonds are so surrendered for exchange, the Issuer shall
execute and the Indenture Trustee shall authenticate and deliver the Bonds which
the Bondholder making the exchange is entitled to receive. Each Bond presented
or surrendered for registration of transfer or exchange shall (if so required by
the Bond Registrar) be duly endorsed by, or be accompanied by a written
instrument of transfer in form reasonably satisfactory to the Bond Registrar
duly executed by the Holder thereof or his attorney duly authorized in writing
with such signature guaranteed by a commercial bank or trust company located or
having a correspondent located in the city of New York. Bonds delivered upon any
such transfer or exchange will evidence the same obligations, and will be
entitled to the same rights and privileges, as the Bonds surrendered.

     No service charge shall be made for any registration of transfer or
exchange of Bonds, but the Bond Registrar shall require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any registration of transfer or exchange of Bonds.

     The Issuer hereby appoints the Indenture Trustee as (i) Certificate
Registrar to keep at its Corporate Trust Office a Certificate Register pursuant
to Section 3.09 of the Trust Agreement in which, subject to such reasonable
regulations as it may prescribe, the Certificate Registrar shall provide for the
registration of Certificates and of transfers and exchanges thereof pursuant to
Section 3.05 of the Trust Agreement and (ii) Bond Registrar under this
Indenture. The Indenture Trustee hereby accepts such appointments.

     Section 4.03 MUTILATED, DESTROYED, LOST OR STOLEN BONDS. If (i) any
mutilated Bond is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Bond, and (ii) there is delivered to the Indenture Trustee such security or
indemnity as may be required by it to hold the Issuer, the Bond Insurer and the
Indenture Trustee harmless, then, in the absence of notice to the Issuer, the
Bond Registrar or the Indenture Trustee that such Bond has been acquired by a
bona fide purchaser, and provided that the requirements of Section 8-405 of the
UCC are met, the Issuer shall execute, and upon its request the Indenture
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Bond, a replacement Bond; PROVIDED,
HOWEVER, that if any such destroyed, lost or stolen Bond, but not a mutilated
Bond, shall have become or within seven days shall be due and payable, instead
of issuing a replacement Bond, the Issuer may pay such destroyed, lost or stolen
Bond when so due or payable without surrender thereof. If, after the delivery of
such replacement Bond or payment of a destroyed, lost or stolen Bond pursuant to
the proviso to the preceding sentence, a bona fide purchaser of the original
Bond in lieu of which such replacement Bond was issued presents for payment such
original Bond, the Issuer, the Bond Insurer and the Indenture Trustee shall be
entitled to recover such replacement Bond (or such payment) from the Person to
whom it was delivered or any Person taking such replacement Bond from such
Person to whom such replacement Bond was delivered or any assignee of such
Person, except a bona fide purchaser, and shall be entitled to recover upon the
security or indemnity provided therefor to the extent of any loss, damage, cost
or expense incurred by the Issuer, the Bond Insurer or the Indenture Trustee in
connection therewith.



                                       32

<PAGE>



     Upon the issuance of any replacement Bond under this Section 4.03, the
Issuer may require the payment by the Holder of such Bond of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and any other reasonable expenses (including the fees and expenses of
the Indenture Trustee) connected therewith.

     Every replacement Bond issued pursuant to this Section 4.03 in replacement
of any mutilated, destroyed, lost or stolen Bond shall constitute an original
additional contractual obligation of the Issuer, whether or not the mutilated,
destroyed, lost or stolen Bond shall be at any time enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Bonds duly issued hereunder.

     The provisions of this Section 4.03 are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Bonds.

     Section 4.04 PERSONS DEEMED OWNERS. Prior to due presentment for
registration of transfer of any Bond, the Issuer, the Bond Insurer, the
Indenture Trustee, the Paying Agent and any agent of the Issuer, the Bond
Insurer or the Indenture Trustee may treat the Person in whose name any Bond is
registered (as of the day of determination) as the owner of such Bond for the
purpose of receiving payments of principal of and interest, if any, on such Bond
and for all other purposes whatsoever, whether or not such Bond be overdue, and
neither the Issuer, the Bond Insurer, the Indenture Trustee, the Paying Agent
nor any agent of the Issuer, the Bond Insurer or the Indenture Trustee shall be
affected by notice to the contrary.

     Section 4.05 CANCELLATION. All Bonds surrendered for payment, registration
of transfer, exchange or redemption shall, if surrendered to any Person other
than the Indenture Trustee, be delivered to the Indenture Trustee and shall be
promptly cancelled by the Indenture Trustee. The Issuer may at any time deliver
to the Indenture Trustee for cancellation any Bonds previously authenticated and
delivered hereunder which the Issuer may have acquired in any manner whatsoever,
and all Bonds so delivered shall be promptly cancelled by the Indenture Trustee.
No Bonds shall be authenticated in lieu of or in exchange for any Bonds
cancelled as provided in this Section 4.05, except as expressly permitted by
this Indenture. All cancelled Bonds may be held or disposed of by the Indenture
Trustee in accordance with its standard retention or disposal policy as in
effect at the time unless the Issuer shall direct by an Issuer Request that they
be destroyed or returned to it; PROVIDED, HOWEVER, that such Issuer Request is
timely and the Bonds have not been previously disposed of by the Indenture
Trustee.

     Section 4.06 BOOK-ENTRY BONDS. The Bonds, upon original issuance, will be
issued in the form of typewritten Bonds representing the Book-Entry Bonds, to be
delivered to The Depository Trust Company, the initial Depository, by, or on
behalf of, the Issuer. The Bonds shall initially be registered on the Bond
Register in the name of Cede & Co., the nominee of the initial Depository, and
no Beneficial Owner will receive a Definitive Bond representing such Beneficial
Owner's interest in such Bond, except as provided in Section 4.08. With respect
to such Bonds, unless and until definitive, fully registered Bonds (the
"Definitive Bonds") have been issued to Beneficial Owners pursuant to Section
4.08:



                                       33

<PAGE>



               (i) the provisions of this Section 4.06 shall be in full force
     and effect;

               (ii) the Bond Registrar, the Paying Agent and the Indenture
     Trustee shall be entitled to deal with the Depository for all purposes of
     this Indenture (including the payment of principal of and interest on the
     Bonds and the giving of instructions or directions hereunder) as the sole
     holder of the Bonds, and shall have no obligation to the Beneficial Owners
     of the Bonds;

               (iii) to the extent that the provisions of this Section 4.06
     conflict with any other provisions of this Indenture, the provisions of
     this Section 4.06 shall control;

               (iv) the rights of Beneficial Owners shall be exercised only
     through the Depository and shall be limited to those established by law and
     agreements between such Owners of Bonds and the Depository and/or the
     Depository Participants. Unless and until Definitive Bonds are issued
     pursuant to Section 4.08, the initial Depository will make book- entry
     transfers among the Depository Participants and receive and transmit
     payments of principal of and interest on the Bonds to such Depository
     Participants; and

               (v) whenever this Indenture requires or permits actions to be
     taken based upon instructions or directions of Holders of Bonds evidencing
     a specified percentage of the Bond Principal Balances of the Bonds, the
     Depository shall be deemed to represent such percentage with respect to the
     Bonds only to the extent that it has received instructions to such effect
     from Beneficial Owners and/or Depository Participants owning or
     representing, respectively, such required percentage of the beneficial
     interest in the Bonds and has delivered such instructions to the Indenture
     Trustee.

     Section 4.07 NOTICES TO DEPOSITORY. Whenever a notice or other
communication to the Bond Holders is required under this Indenture, unless and
until Definitive Bonds shall have been issued to Beneficial Owners pursuant to
Section 4.08, the Indenture Trustee shall give all such notices and
communications specified herein to be given to Holders of the Bonds to the
Depository, and shall have no obligation to the Beneficial Owners.

     Section 4.08 DEFINITIVE BONDS. If (i) the Indenture Trustee determines that
the Depository is no longer willing or able to properly discharge its
responsibilities with respect to the Bonds and the Indenture Trustee is unable
to locate a qualified successor, (ii) the Indenture Trustee elects to terminate
the book-entry system through the Depository or (iii) after the occurrence of an
Event of Default, Beneficial Owners of Bonds representing beneficial interests
aggregating at least a majority of the Bond Principal Balances of the Bonds (for
which purpose the Class 3-A-IO Bonds will be deemed to have a Bond Principal
Balance equal to 5% of the aggregate Bond Principal Balance of the other Classes
of Bonds) advise the Depository in writing that the continuation of a book-entry
system through the Depository is no longer in the best interests of the
Beneficial Owners, then the Depository shall notify all Beneficial Owners and
the Indenture Trustee of the occurrence of any such event and of the
availability of Definitive Bonds to Beneficial Owners requesting the same. Upon
surrender to the Indenture Trustee of the typewritten Bonds representing the
Book-Entry Bonds by the Depository, accompanied by registration instructions,
the Issuer shall execute and the Indenture Trustee shall authenticate the
Definitive Bonds in accordance with the instructions of the


                                       34

<PAGE>



Depository. None of the Issuer, the Bond Registrar or the Indenture Trustee
shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Bonds, the Indenture Trustee shall recognize the
Holders of the Definitive Bonds as Bondholders.

     Section 4.09 TAX TREATMENT. The Issuer has entered into this Indenture, and
the Bonds will be issued with the intention that, for federal, state and local
income, single business and franchise tax purposes, the Bonds will qualify as
indebtedness. The Issuer and the Indenture Trustee (in accordance with Section
6.06 hereof), by entering into this Indenture, and each Bondholder, by its
acceptance of its Bond (and each Beneficial Owner by its acceptance of an
interest in the applicable Book-Entry Bond), agree to treat the Bonds for
federal, state and local income, single business and franchise tax purposes as
indebtedness.

     Section 4.10 SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture shall
cease to be of further effect with respect to the Bonds except as to (i) rights
of registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Bonds, (iii) rights of Bondholders (and the Bond
Insurer, as subrogee of the Bondholders) to receive payments of principal
thereof and interest thereon, (iv) Sections 3.03, 3.04, 3.06, 3.09, 3.17, 3.19
and 3.20, (v) the rights, obligations and immunities of the Indenture Trustee
hereunder (including the rights of the Indenture Trustee under Section 6.07 and
the obligations of the Indenture Trustee under Section 4.11), (vi) the right of
the Derivative Contract Counterparty to receive the related Net Derivative Fee
and (vii) the rights of Bondholders as beneficiaries hereof with respect to the
property so deposited with the Indenture Trustee payable to all or any of them,
and the Indenture Trustee, on demand of and at the expense of the Issuer, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture with respect to the Bonds and shall release and deliver the Collateral
to or upon the order of the Issuer, when

          (A) either

          (1) all Bonds theretofore authenticated and delivered (other than (i)
     Bonds that have been destroyed, lost or stolen and that have been replaced
     or paid as provided in Section 4.03 hereof and (ii) Bonds for whose payment
     money has theretofore been deposited in trust or segregated and held in
     trust by the Issuer and thereafter repaid to the Issuer or discharged from
     such trust, as provided in Section 3.03) have been delivered to the
     Indenture Trustee for cancellation; or

          (2) all Bonds not theretofore delivered to the Indenture Trustee for
     cancellation

               a.   have become due and payable,

               b.   will become due and payable at the Final Scheduled Payment
                    Date within one year, or

               c.   have been called for early redemption and the Trust has been
                    terminated pursuant to Section 8.07 hereof,



                                       35

<PAGE>



and the Issuer, in the case of a. or b. above, has irrevocably deposited or
caused to be irrevocably deposited with the Indenture Trustee cash or direct
obligations of or obligations guaranteed by the United States of America (which
will mature prior to the date such amounts are payable), in trust for such
purpose, in an amount sufficient to pay and discharge the entire indebtedness on
such Bonds then outstanding not theretofore delivered to the Indenture Trustee
for cancellation when due on the Final Scheduled Payment Date or other final
Payment Date and has delivered to the Indenture Trustee and the Bond Insurer a
verification report from a nationally recognized accounting firm certifying that
the amounts deposited with the Indenture Trustee are sufficient to pay and
discharge the entire indebtedness of such Bonds, or, in the case of c. above,
the Issuer shall have complied with all requirements of Section 8.07 hereof,

          (B) the Issuer has paid or caused to be paid all other sums payable
     hereunder and under the Insurance Agreement by the Issuer as evidenced by
     the written consent of the Bond Insurer; and

          (C) the Issuer has delivered to the Indenture Trustee and the Bond
     Insurer an Officer's Certificate and an Opinion of Counsel, each meeting
     the applicable requirements of Section 10.01 hereof, each stating that all
     conditions precedent herein provided for relating to the satisfaction and
     discharge of this Indenture have been complied with and, if the Opinion of
     Counsel relates to a deposit made in connection with Section 4.10(A)(2)b.
     above, such opinion shall further be to the effect that such deposit will
     constitute an "in-substance defeasance" within the meaning of Revenue
     Ruling 85-42, 1985-1 C.B. 36, and in accordance therewith, the Issuer will
     be the owner of the assets deposited in trust for federal income tax
     purposes.

     Section 4.11 APPLICATION OF TRUST MONEY. All monies deposited with the
Indenture Trustee pursuant to Section 4.10 hereof shall be held in trust and
applied by it, in accordance with the provisions of the Bonds and this
Indenture, to the payment, either directly or through any Paying Agent or the
Issuer, Certificate Paying Agent as designee of the Issuer or the Bond Insurer,
as the Indenture Trustee may determine, to the Holders of Securities, of all
sums due and to become due thereon for principal and interest or otherwise; but
such monies need not be segregated from other funds except to the extent
required herein or required by law.

     Section 4.12 SUBROGATION AND COOPERATION. (a) The Issuer and the Indenture
Trustee acknowledge that (i) to the extent the Bond Insurer makes payments under
the Bond Insurance Policy on account of principal of or interest on the Class
1-A-1 Bonds and Class 2-A-1 Bonds, the Bond Insurer will be fully subrogated to
the rights of such Holders to receive such principal and interest from the
Issuer, and (ii) the Bond Insurer shall be paid such principal and interest but
only from the sources and in the manner provided herein and in the Insurance
Agreement for the payment of such principal and interest.

     The Indenture Trustee shall, so long as it is indemnified to its
satisfaction, cooperate in all respects with any reasonable written request by
the Bond Insurer (unless a Bond Insurer Default exists) for action to preserve
or enforce the Bond Insurer's rights or interest under this Indenture or the
Insurance Agreement, consistent with this Indenture and without limiting the
rights of the Bondholders as otherwise set forth in the Indenture, including,
without limitation, upon the


                                       36

<PAGE>



occurrence and continuance of a default under the Insurance Agreement, a request
to take any one or more of the following actions:

               (i) institute Proceedings for the collection of all amounts then
     payable on the Class 1-A-1 Bonds and Class 2-A-1 Bonds, or under this
     Indenture in respect of the Class 1-A-1 Bonds and Class 2-A-1 Bonds and all
     amounts payable under the Insurance Agreement, enforce any judgment
     obtained and collect from the Issuer monies adjudged due;

               (ii) sell or cause to be sold the Trust Estate or any portion
     thereof or rights or interest therein, at one or more public or private
     Sales (as defined in Section 5.15 (a) hereof) called and conducted in any
     manner permitted by law;

               (iii) institute Proceedings from time to time for the complete or
     partial foreclosure of this Indenture; and

               (iv) exercise any remedies of a secured party under the UCC and
     take any other appropriate action to protect and enforce the rights and
     remedies of the Bond Insurer hereunder;

provided, however, action shall be taken pursuant to this Section 4.12 by the
Indenture Trustee to preserve the Bond Insurer's rights or interest under this
Agreement or the Insurance Agreement only to the extent such action is available
to the Class 1-A-1 Bondholders and Class 2-A-1 Bondholders or the Bond Insurer
under other provisions of this Indenture.

     Notwithstanding any provision of this Indenture to the contrary, so long as
no Bond Insurer Default exists, the Bond Insurer shall at all times be treated
as if it were the exclusive owner of all Class 1-A-1 Bonds and Class 2-A-1 Bonds
Outstanding for the purposes of all approvals, consents, waivers and the
institution of any action and the written direction of all remedies, and the
Indenture Trustee shall act in accordance with the written directions of the
Bond Insurer so long as it is indemnified therefor to its reasonable
satisfaction.

     Section 4.13 REPAYMENT OF MONIES HELD BY PAYING AGENT. In connection with
the satisfaction and discharge of this Indenture with respect to the Bonds, all
monies then held by any Person other than the Indenture Trustee under the
provisions of this Indenture with respect to such Bonds shall, upon demand of
the Issuer, be paid to the Indenture Trustee to be held and applied according to
Section 3.05 and thereupon such Person shall be released from all further
liability with respect to such monies.

     Section 4.14 TEMPORARY BONDS. Pending the preparation of any Definitive
Bonds, the Issuer may execute and upon its written direction, the Indenture
Trustee may authenticate and make available for delivery, temporary Bonds that
are printed, lithographed, typewritten, photocopied or otherwise produced, in
any denomination, substantially of the tenor of the Definitive Bonds in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Bonds may
determine, as evidenced by their execution of such Bonds.



                                       37

<PAGE>



     If temporary Bonds are issued, the Issuer will cause Definitive Bonds to be
prepared without unreasonable delay. After the preparation of the Definitive
Bonds, the temporary Bonds shall be exchangeable for Definitive Bonds upon
surrender of the temporary Bonds at the office of the Indenture Trustee located
at 123 Washington Street, New York, New York 10006, without charge to the
Holder. Upon surrender for cancellation of any one or more temporary Bonds, the
Issuer shall execute and the Indenture Trustee shall authenticate and make
available for delivery, in exchange therefor, Definitive Bonds of authorized
denominations and of like tenor, class and aggregate principal amount. Until so
exchanged, such temporary Bonds shall in all respects be entitled to the same
benefits under this Indenture as Definitive Bonds.

     Section 4.15 REPRESENTATION REGARDING ERISA. By acquiring a Bond or
interest therein, each Holder of such Bond or Beneficial Owner of any such
interest will be deemed to represent that either (1) it is not acquiring the
Bond with Plan Assets or (2) (A) the acquisition, holding and transfer of such
Bond will not give rise to a nonexempt prohibited transaction under Section 406
of ERISA or Section 4975 of the Code as a result of the Issuer, the Seller, the
Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master
Servicer, any Subservicer, any other servicer, any administrator, any provider
of credit support, including the Derivative Contract Counterparty, any owner of
the Certificates, or any of their Affiliates being a "Party in Interest" (within
the meaning of ERISA) or Disqualified Person (within the meaning of the Code)
with respect to such Holder or Beneficial Owner that is a Plan and (B) the Bonds
are rated investment grade or better and such person believes that the Bonds are
properly treated as indebtedness without substantial equity features for
purposes of the Department of Labor regulation 29 C.F.R. ss. 2510.3-101, and
agrees to so treat the Bonds. Alternatively, regardless of the rating of the
Bonds, such person may provide the Indenture Trustee and the Owner Trustee with
an opinion of counsel, which opinion of counsel will not be at the expense of
the Issuer, the Seller, any Underwriter, the Owner Trustee, the Indenture
Trustee, the Master Servicer or any successor servicer which opines that the
acquisition, holding and transfer of such Bond or interest therein is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Issuer, the Seller, the Depositor, any Underwriter, the Owner
Trustee, the Indenture Trustee, the Master Servicer or any successor servicer to
any obligation in addition to those undertaken in the Indenture.

                                    ARTICLE V

                              Default and Remedies

     Section 5.01 EVENTS OF DEFAULT. The Issuer shall deliver to the Indenture
Trustee and the Bond Insurer, within five days after learning of the occurrence
of an Event of Default, written notice in the form of an Officer's Certificate
of any event which with the giving of notice and the lapse of time would become
an Event of Default under clause (iii) or (iv) of the definition of "Event of
Default", its status and what action the Issuer is taking or proposes to take
with respect thereto. The Indenture Trustee shall not be deemed to have
knowledge of any Event of Default unless a Responsible Officer has actual
knowledge thereof or unless written notice of such Event of Default is received
by a Responsible Officer and such notice references the Bonds, the Trust Estate
or this Indenture.

     Section 5.02 ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee (i) at the written direction of the Holders of the Group 1
Bonds and Group 2 Bonds representing not less than a majority of the aggregate
Bond Principal Balance of the Group 1 Bonds and Group 2 Bonds shall declare the
principal of the Group 1 Bonds and Group 2 Bonds, together with accrued and
unpaid interest thereon through the date of acceleration, to be immediately due
and payable, and/or (ii) at the written direction of the Holders of the Group 3
Bonds representing not less than a majority of the aggregate Bond Principal
Balance of the Group 3 Bonds (other than the Class 3-A-IO Bonds) and not less
than a majority of the aggregate Notional Amount of the Class 3-A-IO Bonds then
outstanding shall declare the Group 3 Bonds to be immediately due and payable,
in each case by a notice in writing to the Issuer (and to the Indenture Trustee
if such notice is given by Bondholders), and upon any such declaration the
unpaid Bond Principal Balance of the applicable Bonds, together with accrued and
unpaid interest thereon through the date of acceleration, shall become
immediately due and payable; provided, however, that for purposes of this
sentence and for purposes of this Article V, unless a Bond Insurer Default
exists, the Bond Insurer may exercise the rights of all of the Holders of the
Class 1-A-1 Bonds and Class 2-A-1 Bonds.

     At any time after such declaration of acceleration of maturity with respect
to an Event of Default has been made and before a judgment or decree for payment
of the money due has been obtained by the Indenture Trustee as hereinafter in
this Article V provided, Holders of the applicable Bonds representing not less
than a majority of the aggregate Bond Principal Balance of the related Bonds
(other than the Class 3-A-IO Bonds in the case of the Group 3 Bonds) and, in the
case of the Group 3 Bonds, not less than a majority of the aggregate Notional
Amount of the Class 3-A-IO Bonds, by written notice to the Issuer and the
Indenture Trustee, may waive the related Event of Default and rescind and annul
such declaration and its consequences if

               (i) the Issuer or the Bond Insurer has paid or deposited with the
     Indenture Trustee a sum sufficient to pay:

               (A) all payments of principal of and interest on the Bonds and
          all other amounts that would then be due hereunder or upon the Bonds
          if the Event of Default giving rise to such acceleration had not
          occurred;


                                       39

<PAGE>



               (B) all sums paid or advanced by the Indenture Trustee hereunder
          and the reasonable compensation, expenses, disbursements and advances
          of the Indenture Trustee and its agents and counsel; and

               (C) all amounts owed to the Derivative Contract Counterparty; and

               (ii) all Events of Default, other than the nonpayment of the
     principal of the Bonds that has become due solely by such acceleration,
     have been cured or waived as provided in Section 5.12; provided, however,
     the Bond Insurer, so long as no Bond Insurer Default exists, may waive an
     Event of Default regardless of Section 5.02(i) above.

No such rescission shall affect any subsequent default or impair any right
consequent thereto.

     Section 5.03 COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY
                  INDENTURE TRUSTEE.

     (a) The Issuer covenants that if (i) default is made in the payment of any
interest on any Bond when the same becomes due and payable, and such default
continues for a period of five days, or (ii) default is made in the payment of
the principal of or any installment of the principal of any Bond when the same
becomes due and payable, the Issuer shall, upon demand of the Indenture Trustee,
at the direction of the Bond Insurer, so long as no Bond Insurer Default exists,
or if a Bond Insurer Default does exist, (i) at the direction of the Holders of
a majority of the aggregate Bond Principal Balances of the Group 1 Bonds and
Group 2 Bonds, and/or (ii) at the direction of the Holders of a majority of the
aggregate Bond Principal Balances of the Group 3 Bonds (other than the Class
3-A-IO Bonds) and a majority of the Notional Amount of the Class 3-A-IO Bonds,
pay to the Indenture Trustee, for the benefit of the Holders of Bonds, the whole
amount then due and payable on the applicable Bonds for principal and interest,
with interest at the applicable Bond Interest Rate upon the overdue principal,
and in addition thereto such further amount as shall be sufficient to cover the
costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Indenture Trustee and its agents and
counsel.

     (b) In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Indenture Trustee, in its own name and as trustee of an express
trust, and at the direction of the Bond Insurer, so long as no Bond Insurer
Default exists, subject to the provisions of Section 10.16 hereof may institute
a Proceeding for the collection of the sums so due and unpaid, and may prosecute
such Proceeding to judgment or final decree, and may enforce the same against
the Issuer or other obligor upon the Bonds and collect in the manner provided by
law out of the property of the Issuer or other obligor the Bonds, wherever
situated, the monies adjudged or decreed to be payable.

     (c) If an Event of Default occurs and is continuing, the Indenture Trustee,
at the direction of the Bond Insurer, so long as no Bond Insurer Default exists
subject to the provisions of Section 10.16 hereof may, as more particularly
provided in Section 5.04 hereof, in its discretion, proceed to protect and
enforce its rights and the rights of the Bondholders and the Bond Insurer, by
such appropriate Proceedings as the Indenture Trustee shall be directed by the
Bond Insurer, so long as no Bond Insurer Default exists, to protect and enforce
any such rights, whether for the specific enforcement of any covenant or
agreement in this Indenture or in aid of the exercise of any power


                                       40

<PAGE>



granted herein, or to enforce any other proper remedy or legal or equitable
right vested in the Indenture Trustee by this Indenture or by law.

     (d) In case there shall be pending, relative to the Issuer or any other
obligor upon the Bonds or any Person having or claiming an ownership interest in
the Trust Estate, Proceedings under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other comparable judicial Proceedings relative to the Issuer
or other obligor upon the Bonds, or to the creditors or property of the Issuer
or such other obligor, the Indenture Trustee, at the direction of the Bond
Insurer, so long as no Bond Insurer Default exists, irrespective of whether the
principal of any Bonds shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Indenture Trustee shall
have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such Proceedings or otherwise:

               (i) to file and prove a claim or claims for the whole amount of
     principal and interest owing and unpaid in respect of the Bonds and to file
     such other papers or documents as may be necessary or advisable in order to
     have the claims of the Indenture Trustee (including any claim for
     reasonable compensation to the Indenture Trustee and each predecessor
     Indenture Trustee, and their respective agents, attorneys and counsel, and
     for reimbursement of all expenses and liabilities incurred, and all
     advances made, by the Indenture Trustee and each predecessor Indenture
     Trustee, except as a result of negligence or bad faith), the Bond Insurer
     and of the Bondholders allowed in such Proceedings;

               (ii) unless prohibited by applicable law and regulations, to vote
     on behalf of the Holders of Bonds in any election of a trustee, a standby
     trustee or Person performing similar functions in any such Proceedings;

               (iii) to collect and receive any monies or other property payable
     or deliverable on any such claims and to distribute all amounts received
     with respect to the claims of the Bondholders, the Bond Insurer and of the
     Indenture Trustee on their behalf, and

               (iv) to file such proofs of claim and other papers or documents
     as may be necessary or advisable in order to have the claims of the
     Indenture Trustee, the Bond Insurer or the Holders of Bonds allowed in any
     judicial proceedings relative to the Issuer, its creditors and its
     property;

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such Bondholders to make
payments to the Indenture Trustee, with the consent of the Bond Insurer so long
as no Bond Insurer Default exists, and, in the event that the Indenture Trustee
shall consent to the making of payments directly to such Bondholders, to pay to
the Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Indenture Trustee and each
predecessor Indenture Trustee and all amounts due to the Bond Insurer.

     (e) Nothing herein contained shall be deemed to authorize the Indenture
Trustee to authorize or consent to or vote for or accept or adopt on behalf of
any Bondholder any plan of reorganization, arrangement, adjustment or
composition affecting the Bonds or the rights of any Holder thereof or to
authorize the Indenture Trustee to vote in respect of the claim of any
Bondholder in any such proceeding except, as aforesaid, to vote for the election
of a trustee in bankruptcy or similar Person.

     (f) All rights of action and of asserting claims under this Indenture, or
under any of the Bonds, may be enforced by the Indenture Trustee without the
possession of any of the Bonds or the production thereof in any trial or other
Proceedings relative thereto, and any such action or proceedings instituted by
the Indenture Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment, subject to the payment of the expenses,
disbursements and compensation of the Indenture Trustee, each predecessor
Indenture Trustee and their respective agents and attorneys, shall be for the
ratable benefit of the Holders of the Bonds, subject to Section 5.05 hereof.

     (g) In any Proceedings brought by the Indenture Trustee with the consent of
the Bond Insurer so long as no Bond Insurer Default exists (and also any
Proceedings involving the interpretation of any provision of this Indenture to
which the Indenture Trustee shall be a party), the Indenture Trustee shall be
held to represent all the Holders of the Bonds, and it shall not be necessary to
make any Bondholder a party to any such Proceedings.

     Section 5.04 REMEDIES; PRIORITIES. (a) If an Event of Default shall have
occurred and be continuing and if an acceleration has been declared and not
rescinded pursuant to Section 5.02 hereof, the Indenture Trustee subject to the
provisions of Section 10.16 hereof may with the consent of the Bond Insurer, so
long as a Bond Insurer Default does not exist, and shall at the direction of the
Bond Insurer so long as no Bond Insurer Default exists, in each case do one or
more of the following (subject to Section 5.05 hereof):

               (i) institute Proceedings in its own name and as trustee of an
     express trust for the collection of all amounts then payable on the Bonds
     or under this Indenture with respect thereto, whether by declaration or
     otherwise, and all amounts payable under the Insurance Agreement, enforce
     any judgment obtained, and collect from the Issuer and any other obligor
     upon such Bonds monies adjudged due;

               (ii) institute Proceedings from time to time for the complete or
     partial foreclosure of this Indenture with respect to the Trust Estate;

               (iii) exercise any remedies of a secured party under the UCC and
     take any other appropriate action to protect and enforce the rights and
     remedies of the Indenture Trustee and the Holders of the Bonds and the Bond
     Insurer; and

PROVIDED, HOWEVER, that so long as a Bond Insurer Default exists the Indenture
Trustee may not sell or otherwise liquidate the Trust Estate following an Event
of Default, unless (A) the Indenture Trustee obtains (i) the consent of the
Holders of 100% of the aggregate Bond Principal Balance of the Group 1 Bonds and
Group 2 Bonds and/or (ii) the consent of the Holders of 100% of the aggregate
Bond Principal Balance of the Group 3 Bonds and 50% of the Notional Amount of
the Class 3-A-IO Bonds, (B) the proceeds of such sale or liquidation
distributable to the Holders of the applicable Bonds are sufficient to discharge
in full all amounts then due and unpaid upon such Bonds for principal and
interest and to reimburse the Bond Insurer for any amounts drawn under the Bond
Insurance Policy and any other amounts due to the Bond Insurer under the
Insurance Agreement or (C) the Indenture Trustee determines that the Mortgage
Loans will not continue to provide sufficient funds for the payment of principal
of and interest on the applicable Bonds as they would have become due if the
Bonds had not been declared due and payable, and the Indenture Trustee obtains
(i) the consent of the Holders of a majority of the aggregate Bond Principal
Balance of the Group 1 Bonds and Group 2 Bonds and/or (ii) the consent of the
Holders of a majority of the aggregate Bond Principal Balance of the Group 1
Bonds and a majority of the Notional Amount of the Class 3-A-IO Bonds. In
determining such sufficiency or insufficiency with respect to clause (B) and
(C), the Indenture Trustee may, but need not, obtain and rely upon an opinion
(obtained at the expense of the Trust) of an Independent investment banking or
accounting firm of national reputation as to the feasibility of such proposed
action and as to the sufficiency of the Trust Estate for such purpose.
Notwithstanding the foregoing, so long as an Event of Servicer Termination has
not occurred, any Sale of the Trust Estate shall be made subject to the
continued servicing of the Mortgage Loans by the Master Servicer as provided in
the Servicing Agreement.

     (b) If the Indenture Trustee collects any money or property with respect to
the Group 1 Loans or Group 2 Loans pursuant to this Article V, it shall pay out
the money or property in the following order; PROVIDED, HOWEVER, that any

     The Indenture Trustee may fix a record date and Payment Date for any
payment to Bondholders pursuant to this Section 5.04. With respect to any
acceleration at the direction of the Bond Insurer, the first Payment Date after
the acceleration shall be the first Payment Date after the acceleration. At
least 15 days before such record date, the Indenture Trustee shall mail to each
Bondholder a notice that states the record date, the Payment Date and the amount

     Section 5.05 OPTIONAL PRESERVATION OF THE TRUST ESTATE. If the Bonds have
been declared to be due and payable under Section 5.02 following an Event of
Default and such declaration and its consequences have not been rescinded and
annulled, the Indenture Trustee may, with the consent of the Bond Insurer (which
consent shall not be required if a Bond Insurer Default exists), and shall, at
the direction of the Bond Insurer so long as no Bond Insurer Default exists,
elect to take and maintain possession of the Trust Estate. It is the desire of
the parties hereto and the Bondholders that there be at all times sufficient
funds for the payment of principal of and interest on the Bonds and other
obligations of the Issuer including payment to the Bond Insurer, and the
Indenture Trustee, unless directed otherwise by the Bond Insurer, shall take
such desire into account when determining whether or not to take and maintain
possession of the Trust Estate. In determining whether to take and maintain
possession of the Trust Estate, the Indenture Trustee may, but need not, obtain
and rely upon an opinion of an Independent investment banking or accounting firm
of national reputation as to the feasibility of such proposed action and as to
the sufficiency of the Trust Estate for such purpose.

     Section 5.06 LIMITATION OF SUITS. No Holder of any Bond shall have any
right to institute any Proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless and subject to the provisions of Section 10.16 hereof


                                       45

<PAGE>



               (i) such Holder has previously given written notice to the
     Indenture Trustee of a continuing Event of Default;

               (ii) the Holders of not less than 25% of the aggregate Bond
     Principal Balances of the Bonds (for which purpose the Class 3-A-IO Bonds
     will be deemed to have a Bond Principal Balance equal to 5% of the
     aggregate Bond Principal Balance of the other Classes of Bonds) have made a
     written request to the Indenture Trustee to institute such Proceeding in
     respect of such Event of Default in its own name as Indenture Trustee
     hereunder;

               (iii) such Holder or Holders have offered to the Indenture
     Trustee reasonable indemnity against the costs, expenses and liabilities to
     be incurred in complying with such request;

               (iv) the Indenture Trustee for 60 days after its receipt of such
     notice of request and offer of indemnity has failed to institute such
     Proceedings;

               (v) no direction inconsistent with such written request has been
     given to the Indenture Trustee during such 60-day period by the Holders of
     a majority of the Bond Principal Balances of the Bonds and a majority of
     the Notional Amount of the Class 3-A-IO Bonds; and

               (vi) such Holder or Holders have the written consent of the Bond
     Insurer, unless a Bond Insurer Default exists.

It is understood and intended that no one or more Holders of Bonds shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of Bonds or to obtain or to seek to obtain priority or preference over
any other Holders or to enforce any right under this Indenture, except in the
manner herein provided.

     Subject to the last paragraph of Section 5.11 herein, in the event the
Indenture Trustee shall receive conflicting or inconsistent requests and
indemnity from two or more groups of Holders of Bonds, each representing less
than a majority of the Bond Principal Balances of the Bonds (for which purpose
the Class 3-A-IO Bonds will be deemed to have a Bond Principal Balance equal to
5% of the aggregate Bond Principal Balance of the other Classes of Bonds), the
Indenture Trustee in its sole discretion may determine what action, if any,
shall be taken, notwithstanding any other provisions of this Indenture.

     Section 5.07 UNCONDITIONAL RIGHTS OF BONDHOLDERS TO RECEIVE PRINCIPAL AND
INTEREST. Notwithstanding any other provisions in this Indenture, the Holder of
any Bond shall have the right, which is absolute and unconditional, to receive
payment of the principal of and interest, if any, on such Bond on or after the
respective due dates thereof expressed in such Bond or in this Indenture and to
institute suit for the enforcement of any such payment, and such right shall not
be impaired without the consent of such Holder.

     Section 5.08 RESTORATION OF RIGHTS AND REMEDIES. If the Indenture Trustee
or any Bondholder has instituted any Proceeding to enforce any right or remedy
under this Indenture and such Proceeding has been discontinued or abandoned for
any reason or has been determined adversely to the Indenture Trustee, the Bond
Insurer or to such Bondholder, then and in every such case the Issuer, the
Indenture Trustee, the Bond Insurer and the Bondholders shall, subject to any
determination in such Proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Indenture Trustee, the Bond Insurer and the Bondholders shall continue as though
no such Proceeding had been instituted.

     Section 5.09 RIGHTS AND REMEDIES CUMULATIVE. No right or remedy herein
conferred upon or reserved to the Indenture Trustee, to the Bond Insurer or to
the Bondholders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative and
in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

     Section 5.10 DELAY OR OMISSION NOT A WAIVER. No delay or omission of the
Indenture Trustee, the Bond Insurer or any Holder of any Bond to exercise any
right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article V or by law to the
Indenture Trustee, the Bond Insurer or to the Bondholders may be exercised from
time to time, and as often as may be deemed expedient, by the Indenture Trustee,
the Bond Insurer or by the Bondholders, as the case may be.

     Section 5.11 CONTROL BY BOND INSURER. The Bond Insurer, unless a Bond
Insurer Default exists, or (i) the Holders of a majority of the aggregate Bond
Principal Balances of Group 1 Bonds and Group 2 Bonds and/or (ii) the Holders of
a majority of the aggregate Bond Principal Balances of Group 3 Bonds (for which
purpose the Class 3-A-IO Bonds will be deemed to have a Bond Principal Balance
equal to 5% of the aggregate Bond Principal Balance of the other Classes of
Bonds), if a Bond Insurer Default exists, shall have the right (subject to the
provisions of Section 5.06) to direct the time, method and place of conducting
any Proceeding for any remedy available to the Indenture Trustee with respect to
the Bonds or exercising any trust or power conferred on the Indenture Trustee;
provided that:


               (i) such direction shall not be in conflict with any rule of law
     or with this Indenture;

               (ii) if a Bond Insurer Default exists, any direction to the
     Indenture Trustee to sell or liquidate the Trust Estate shall be by (A)
     Holders of Group 1 Bonds and Group 2 Bonds representing not less than 100%
     of the Bond Principal Balances of the Class 1-A-1, Class 2-A-1 and Class
     1-B-1 Bonds and/or (B) Holders of Group 3 Bonds representing not less than
     100% of the Bond Principal Balances of the Group 3 Bonds (other than the
     Class 3-A-IO Bonds) and 100% of the Notional Amount of the Class 3-A-IO
     Bonds;



                                       47

<PAGE>



               (iii) if the conditions set forth in Section 5.05 hereof have
     been satisfied and the Indenture Trustee, with the consent of the Bond
     Insurer (which consent shall not be required if a Bond Insurer Default
     exists), elects to retain the Trust Estate pursuant to such Section, then
     any direction to the Indenture Trustee by (A) Holders of Bonds representing
     less than 100% of the Bond Principal Balances of the Group 1 Bonds and
     Group 2 Bonds and /or (ii) Holders of Bonds representing less than 100% of
     the Bond Principal Balances of the Group 3 Bonds and less than 100% of the
     Notional Amount of the Class 3-A-IO Bonds to sell or liquidate the related
     portion of the Trust Estate shall be of no force and effect; and

               (iv) if a Bond Insurer Default exists, the Indenture Trustee may
     take any other action deemed proper by the Indenture Trustee that is not
     inconsistent with such direction of the Holders of Bonds representing a
     majority of the Bond Principal Balances of the Bonds.

Notwithstanding the rights of Bondholders set forth in this Section, subject to
Section 6.01, the Indenture Trustee need not take any action that it determines
might involve it in liability.

     Section 5.12 WAIVER OF PAST DEFAULTS. Prior to the declaration of the
acceleration of the maturity of the Bonds as provided in Section 5.02 hereof,
the Holders of Bonds representing not less than a majority of the aggregate Bond
Principal Balance of the Bonds and a majority of the Notional Amount of the
Class 3-A-IO Bonds may waive any past Event of Default and its consequences
except an Event of Default (a) with respect to payment of principal of or
interest on any of the Bonds, (b) in respect of a covenant or provision hereof
which cannot be modified or amended without the consent of the Holder of each
Bond or (c) the waiver of which would materially and adversely affect the
interests of the Bond Insurer or modify its obligation under the Bond Insurance
Policy. In the case of any such waiver, the Issuer, the Indenture Trustee and
the Holders of the Bonds shall be restored to their former positions and rights
hereunder, respectively, but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereto.

     Upon any such waiver, any Event of Default arising therefrom shall be
deemed to have been cured and not to have occurred, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Event of
Default or impair any right consequent thereto.

     Section 5.13 UNDERTAKING FOR COSTS. All parties to this Indenture agree,
and each Holder of any Bond and each Beneficial Owner of any interest therein by
such Holder's or Beneficial Owner's acceptance thereof shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.13 shall not apply to (a) any suit instituted by
the Indenture Trustee, (b) any suit instituted by any Bondholder, or group of
Bondholders, in each case holding in the aggregate more than 10% of the Bond
Principal Balances of the Bonds or (c) any suit instituted by any Bondholder for
the enforcement of the payment of


                                       48

principal of or interest on any Bond on or after the respective due dates
expressed in such Bond and in this Indenture.

     Section 5.14 WAIVER OF STAY OR EXTENSION LAWS. The Issuer covenants (to the
extent that it may lawfully do so) that it will not at any time insist upon, or
plead or in any manner whatsoever, claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, that may affect the covenants or the performance of this Indenture; and
the Issuer (to the extent that it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it shall not
hinder, delay or impede the execution of any power herein granted to the
Indenture Trustee, but will suffer and permit the execution of every such power
as though no such law had been enacted.

     Section 5.15 SALE OF TRUST ESTATE. (a) The power to effect any sale or
other disposition (a "Sale") of any portion of the Trust Estate pursuant to
Section 5.04 hereof is expressly subject to the provisions of Section 5.05
hereof and this Section 5.15. The power to effect any such Sale shall not be
exhausted by any one or more Sales as to any portion of the Trust Estate
remaining unsold, but shall continue unimpaired until the entire Trust Estate
shall have been sold or all amounts payable on the Bonds and under this
Indenture and under the Insurance Agreement shall have been paid. The Indenture
Trustee with the consent of the Bond Insurer (which consent shall not be
required if a Bond Insurer Default exists), may from time to time postpone any
public Sale by public announcement made at the time and place of such Sale. The
Indenture Trustee hereby expressly waives its right to any amount fixed by law
as compensation for any Sale.

     (b) The Indenture Trustee shall not in any private Sale sell the Trust
Estate, or any portion thereof, unless

          (1) the Bond Insurer, unless a Bond Insurer Default exists, or the
     Holders of all Bonds if a Bond Insurer Default exists, consent to or direct
     the Indenture Trustee to make, such Sale, or

          (2) the proceeds of such Sale would be not less than the entire amount
     which would be payable to the Bondholders under the Bonds and the Bond
     Insurer in respect of amounts drawn under the Bond Insurance Policy and any
     other amounts due to the Bond Insurer under the Insurance Agreement, in
     full payment thereof in accordance with Section 5.02 hereof, on the Payment
     Date next succeeding the date of such Sale, or

          (3) the Indenture Trustee determines that the conditions for retention
     of the Trust Estate set forth in Section 5.05 hereof cannot be satisfied
     (in making any such determination, the Indenture Trustee may rely upon an
     opinion of an Independent investment banking firm obtained and delivered as
     provided in Section 5.05 hereof), and the Bond Insurer consents to such
     Sale, or if a Bond Insurer Default exists, the Holders of Bonds
     representing at least 100% of the Bond Principal Balances of the Class
     1-A-1, Class 2-A-1 and Class 1-B-1 Bonds consent to such Sale.

The purchase by the Indenture Trustee of all or any portion of the Trust Estate
at a private Sale shall not be deemed a Sale or other disposition thereof for
purposes of this Section 5.15(b).


                                       49

<PAGE>



     (c) Unless the Bond Insurer, or if a Bond Insurer Default exists, the
Holders representing at least 66-2/3% of the Bond Principal Balances of the
Bonds have otherwise consented or directed the Indenture Trustee, at any public
Sale of all or any portion of the Trust Estate at which a minimum bid equal to
or greater than the amount described in paragraph (2) of subsection (b) of this
Section 5.15 has not been established by the Indenture Trustee and no Person
bids an amount equal to or greater than such amount, the Indenture Trustee, as
trustee for the benefit of the Holders of the Bonds, shall bid an amount at
least $1.00 more than the highest other bid.

     (d) In connection with a Sale of all or any portion of the Trust Estate,

          (1) any Holder or Holders of Bonds may bid for and purchase the
     property offered for sale, and upon compliance with the terms of sale may
     hold, retain and possess and dispose of such property, without further
     accountability, and may, in paying the purchase money therefor, deliver any
     Bonds or claims for interest thereon in lieu of cash up to the amount which
     shall, upon distribution of the net proceeds of such sale, be payable

     less than the amount due thereon, shall be returned to the Holders thereof
     after being appropriately stamped to show such partial payment;

          (2) the Indenture Trustee, with the consent of the Bond Insurer so
     long as no Bond Insurer Default exists, may bid for and acquire the
     property offered for Sale in connection with any Sale thereof, and, subject
     to any requirements of, and to the extent permitted by, applicable law in
     connection therewith, may purchase all or any portion of the Trust Estate
     in a private sale, and, in lieu of paying cash therefor, may make
     settlement for the purchase price by crediting the gross Sale price against
     the sum of (A) the amount which would be distributable to the Holders of
     the Bonds and Holders of Certificates and amounts distributable to the Bond
     Insurer as a result of such Sale in accordance with Section 5.04(b) hereof
     on the Payment Date next succeeding the date of such Sale and (B) the
     expenses of the Sale and of any Proceedings in connection therewith which
     are reimbursable to it, without being required to produce the Bonds in
     order to complete any such Sale or in order for the net Sale price to be
     credited against such Bonds, and any property so acquired by the Indenture
     Trustee shall be held and dealt with by it in accordance with the
     provisions of this Indenture;

          (3) the Indenture Trustee shall execute and deliver an appropriate
     instrument of conveyance, prepared by the Issuer and satisfactory to the
     Indenture Trustee, transferring its interest in any portion of the Trust
     Estate in connection with a Sale thereof;

          (4) the Indenture Trustee is hereby irrevocably appointed the agent
     and attorney- in-fact of the Issuer to transfer and convey its interest in
     any portion of the Trust Estate in connection with a Sale thereof, and to
     take all action necessary to effect such Sale; and

     of any conditions precedent or see to the application of any monies.

     Section 5.16 ACTION ON BONDS. The Indenture Trustee's right to seek and
recover judgment on the Bonds or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Bondholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Issuer or by the levy of any
execution under such judgment upon any portion of the Trust Estate or upon any
of the assets of the Issuer. Any money or property collected by the Indenture
Trustee shall be applied in accordance with Section 5.04(b) hereof.

     Section 5.17 PERFORMANCE AND ENFORCEMENT OF CERTAIN OBLIGATIONS. (a)
Promptly following a request from the Indenture Trustee to do so, the Issuer in
its capacity as holder of the Mortgage Loans, shall take all such lawful action
as the Indenture Trustee or the Bond Insurer may request to cause the Issuer to
compel or secure the performance and observance by the Seller and the Master
Servicer, as applicable, of each of their obligations to the Issuer under or in
connection with the Mortgage Loan Sale and Contribution Agreement, any
Subsequent Mortgage Loan Sale and Contribution Agreement and the Servicing
Agreement, and to exercise any and all rights, remedies, powers and privileges
lawfully available to the Issuer under or in connection with the Mortgage Loan

including the transmission of notices of default on the part of the Seller or
the Master Servicer thereunder and the institution of legal or administrative
actions or proceedings to compel or secure performance by the Seller or the
Master Servicer of each of their obligations under the Mortgage Loan Sale and
Contribution Agreement, any Subsequent Mortgage Loan Sale and Contribution
Agreement and the Servicing Agreement. So long as no Bond Insurer Default

successor to the Master Servicer (other than the Indenture Trustee) under the
Servicing Agreement.

     (b) The Indenture Trustee, as pledgee of the Mortgage Loans, subject to the
rights of the Bond Insurer under this Agreement and the Servicing Agreement,
may, and at the direction (which direction shall be in writing or by telephone
(confirmed in writing promptly thereafter)) of the Bond Insurer or if a Bond
Insurer Default exists, of the Holders of 66-2/3% of the Bond Principal Balances
of the Bonds, shall exercise all rights, remedies, powers, privileges and claims
of the Issuer against the Seller or the Master Servicer under or in connection
with the Mortgage Loan Sale and Contribution Agreement, any Subsequent Mortgage
Loan Sale and Contribution Agreement and the Servicing Agreement, including the
right or power to take any action to compel or secure performance or observance

obligations to the Issuer thereunder and to give any consent, request, notice,
direction, approval, extension or waiver under the Mortgage Loan Sale and
Contribution Agreement and Contribution Agreement, any Subsequent Mortgage Loan
Sale and Contribution Agreement and the Servicing Agreement, as the case may be,
and any right of the Issuer to take such action shall not be suspended.

                              The Indenture Trustee

     Section 6.01 DUTIES OF INDENTURE TRUSTEE. (a) If an Event of Default has
occurred and is continuing, the Indenture Trustee shall exercise the rights and
powers vested in it by this Indenture and use the same degree of care and skill
in their exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person's own affairs.

     (b) Except during the continuance of an Event of Default:

               (i) the Indenture Trustee undertakes to perform such duties and
     only such duties as are specifically set forth in this Indenture and no
     implied covenants or obligations shall be read into this Indenture against
     the Indenture Trustee; and

               (ii) in the absence of bad faith on its part, the Indenture
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Indenture Trustee and conforming to the
     requirements of this Indenture; however, the Indenture Trustee shall
     examine the certificates and opinions to determine whether or not they
     conform to the requirements of this Indenture.

     (c) The Indenture Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful
misconduct, except that:

               (i) this paragraph does not limit the effect of paragraph (b) of
     this Section 6.01;

               (ii) the Indenture Trustee shall not be liable for any error of
     judgment made in good faith by a Responsible Officer unless it is proved
     that the Indenture Trustee was negligent in ascertaining the pertinent
     facts; and

               (iii) the Indenture Trustee shall not be liable with respect to
     any action it takes or omits to take in good faith in accordance with a
     direction received by it (A) from Bondholders or from the Issuer, which
     they are entitled to give under the Basic Documents or (B) from the Bond
     Insurer, which it is entitled to give under the Basic Documents.

     (d) The Indenture Trustee shall not be liable for interest on any money
received by it except as the Indenture Trustee may agree in writing with the
Issuer.

     (e) Money held in trust by the Indenture Trustee need not be segregated
from other trust funds except to the extent required by law or the terms of this
Indenture or the Trust Agreement.

     (f) No provision of this Indenture shall require the Indenture Trustee to
expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that


                                       52

<PAGE>



repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

     (g) Every provision of this Indenture relating to the conduct or affecting
the liability of or affording protection to the Indenture Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

     (h) The Indenture Trustee shall act in accordance with Sections 6.03 and
6.04 of the Servicing Agreement and shall act as successor to the Master
Servicer or appoint a successor Master Servicer in accordance with Section 6.02
of the Servicing Agreement.

     Section 6.02 RIGHTS OF INDENTURE TRUSTEE. (a) The Indenture Trustee may
rely on any document believed by it to be genuine and to have been signed or
presented by the proper person. The Indenture Trustee need not investigate any
fact or matter stated in the document.

     (b) Before the Indenture Trustee acts or refrains from acting, it may
require an Officer's Certificate or an Opinion of Counsel. The Indenture Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on an Officer's Certificate or Opinion of Counsel.

     (c) The Indenture Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through agents or
attorneys or a custodian or nominee.

     (d) The Indenture Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers; PROVIDED, HOWEVER, that the Indenture Trustee's conduct does
not constitute willful misconduct, negligence or bad faith.

     (e) The Indenture Trustee may consult with counsel, and the advice or
Opinion of Counsel with respect to legal matters relating to this Indenture and
the Bonds shall be full and complete authorization and protection from liability
in respect to any action taken, omitted or suffered by it hereunder in good
faith and in accordance with the advice or opinion of such counsel.

     (f) For the limited purpose of effecting any action to be undertaken by the
Indenture Trustee, but not specifically as a duty of the Indenture Trustee in
the Indenture, the Indenture Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder, either directly or by or through
agents, attorneys, custodians or nominees appointed with due care, and shall not
be responsible for any willful misconduct or negligence on the part of any
agent, attorney, custodian or nominee so appointed.

     (g) The Indenture Trustee or its Affiliates are permitted to receive
additional compensation that could be deemed to be in the Indenture Trustee's
economic self-interest for (i) serving as investment adviser, administrator,
shareholder servicing agent, custodian or sub-custodian with respect to certain
of the Eligible Investments, (ii) using Affiliates to effect transactions in
certain Eligible Investments and (iii) effecting transactions in certain
Eligible Investments. Such compensation shall not be considered an amount that
is reimbursable or payable to the Indenture Trustee (i) as part of the Indenture
Trustee Fee, (ii) pursuant to Sections 3.05(d), 3.05(h), 5.04(b), 6.07 or

     Section 6.03 INDIVIDUAL RIGHTS OF INDENTURE TRUSTEE. The Indenture Trustee
in its individual or any other capacity may become the owner or pledgee of Bonds
and may otherwise deal with the Issuer or its Affiliates with the same rights it
would have if it were not Indenture Trustee, subject to the requirements of the
Trust Indenture Act. Any Bond Registrar, co-registrar or co-paying agent may do
the same with like rights. However, the Indenture Trustee must comply with
Sections 6.11 and 6.12 hereof.

     Section 6.04 INDENTURE TRUSTEE'S DISCLAIMER. The Indenture Trustee shall
not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Bonds, it shall not be accountable for the
Issuer's use of the proceeds from the Bonds, and it shall not be responsible for
any statement of the Issuer in the Indenture or in any document issued in
connection with the sale of the Bonds or in the Bonds other than the Indenture
Trustee's certificate of authentication.

     Section 6.05 NOTICE OF EVENT OF DEFAULT. Subject to Section 5.01, the
Indenture Trustee shall promptly mail to each Bondholder and the Bond Insurer
notice of the Event of Default after it is known to a Responsible Officer of the
Indenture Trustee, unless such Event of Default shall have been waived or cured.
Except in the case of an Event of Default in payment of principal of or interest
on any Bond, the Indenture Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of Bondholders.

     Section 6.06 REPORTS BY INDENTURE TRUSTEE TO HOLDERS AND TAX
ADMINISTRATION. The Indenture Trustee shall deliver to each Bondholder such
information as may be required to enable such holder to prepare its federal and
state income tax returns.

     The Indenture Trustee shall prepare and file (or cause to be prepared and
filed), on behalf of the Owner Trustee, all tax returns (if any) and information
reports, tax elections and such annual or other reports of the Issuer as are
necessary for preparation of tax returns and information reports as provided in
Section 5.03 of the Trust Agreement, including without limitation Form 1099. All
tax returns and information reports shall be signed by the Owner Trustee as
provided in Section 5.03 of the Trust Agreement.

     Section 6.07 COMPENSATION AND INDEMNITY. The Issuer shall pay to the
Indenture Trustee on each Payment Date reasonable compensation for its services.
The amount of the Indenture Trustee's Fee shall be paid by the Master Servicer
to the Indenture Trustee on each Payment Date pursuant to Section 3.07(a)(x) of
the Servicing Agreement and all amounts owing to the Indenture Trustee hereunder
(including amounts owing from the Issuer for indemnification and otherwise) in
excess of such amount shall be paid solely as provided in Section 3.05(d)(ix),
Section 3.05(h)(viii) and Section 5.04(b) hereof. The Indenture Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Issuer shall reimburse the Indenture Trustee for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, in addition to compensation for its services. Such expenses shall
include reasonable compensation and expenses, disbursements and advances of the
Indenture Trustee's agents, counsel, accountants and experts. The Issuer shall
indemnify the Indenture Trustee against any and all loss, liability or expense
(including attorneys' fees) incurred by it in connection with the administration
of this Trust and the performance of its duties hereunder. The Indenture Trustee
shall notify the Issuer promptly of any


                                       54

<PAGE>



claim for which it may seek indemnity. Failure by the Indenture Trustee to so
notify the Issuer shall not relieve the Issuer of its obligations hereunder. The
Issuer shall defend any such claim, and the Indenture Trustee may have separate
counsel and the Issuer shall pay the fees and expenses of such counsel. The
Issuer is not obligated to reimburse any expense or indemnify against any loss,
liability or expense incurred by the Indenture Trustee through the Indenture
Trustee's own willful misconduct, negligence or bad faith.

     The Issuer's payment obligations to the Indenture Trustee pursuant to this
Section 6.07 shall survive the discharge of this Indenture and the termination
or resignation of the Indenture Trustee. When the Indenture Trustee incurs
expenses after the occurrence of an Event of Default with respect to the Issuer,
the expenses are intended to constitute expenses of administration under Title
11 of the United States Code or any other applicable federal or state
bankruptcy, insolvency or similar law.

     Section 6.08 REPLACEMENT OF INDENTURE TRUSTEE. No resignation or removal of
the Indenture Trustee and no appointment of a successor Indenture Trustee shall
become effective until the acceptance of appointment by the successor Indenture
Trustee pursuant to this Section 6.08. The Indenture Trustee may resign at any
time by so notifying the Issuer and the Bond Insurer. The Bond Insurer or, if a
Bond Insurer Default exists, the Holders of a majority of Bond Principal
Balances of the Bonds (for which purpose the Class 3-A-IO Bonds will be deemed
to have a Bond Principal Balance equal to 5% of the aggregate Bond Principal
Balance of the other Classes of Bonds) may remove the Indenture Trustee by so
notifying the Indenture Trustee and the Bond Insurer and may appoint a successor
Indenture Trustee. The Issuer shall, with the consent of the Bond Insurer so
long as no Bond Insurer Default exists, remove the Indenture Trustee if:

               (i) the Indenture Trustee fails to comply with Section 6.11
     hereof;

               (ii) the Indenture Trustee is adjudged a bankrupt or insolvent;

               (iii) a receiver or other public officer takes charge of the
     Indenture Trustee or its property; or

               (iv) the Indenture Trustee otherwise becomes incapable of acting.

     If the Indenture Trustee resigns or is removed or if a vacancy exists in
the office of the Indenture Trustee for any reason (the Indenture Trustee in
such event being referred to herein as the retiring Indenture Trustee), the
Issuer shall, with the consent of the Bond Insurer so long as no Bond Insurer
Default exists, promptly appoint a successor Indenture Trustee.

     A successor Indenture Trustee shall deliver a written acceptance of its
appointment to the retiring Indenture Trustee, to the Bond Insurer and to the
Issuer. Thereupon, the resignation or removal of the retiring Indenture Trustee
shall become effective, and the successor Indenture Trustee shall have all the
rights, powers and duties of the Indenture Trustee under this Indenture. The
successor Indenture Trustee shall mail a notice of its succession to
Bondholders. The retiring Indenture Trustee shall promptly transfer all property
held by it as Indenture Trustee to the successor Indenture Trustee.



                                       55

<PAGE>



     If a successor Indenture Trustee does not take office within 60 days after
the retiring Indenture Trustee resigns or is removed, the retiring Indenture
Trustee, the Issuer, the Bond Insurer or the Holders of a majority of Bond
Principal Balances of the Bonds (for which purpose the Class 3-A-IO Bonds will
be deemed to have a Bond Principal Balance equal to 5% of the aggregate Bond
Principal Balance of the other Classes of Bonds) may petition any court of
competent jurisdiction for the appointment of a successor Indenture Trustee.

     Notwithstanding the replacement of the Indenture Trustee pursuant to this
Section, the Issuer's obligations under Section 6.07 shall continue for the
benefit of the retiring Indenture Trustee.

     Section 6.09 SUCCESSOR INDENTURE TRUSTEE BY MERGER. If the Indenture
Trustee consolidates with, merges or converts into, or transfers all or
substantially all of its corporate trust business or assets to, another
corporation or banking association, the resulting, surviving or transferee
corporation, without any further act, shall be the successor Indenture Trustee;
provided, that such corporation or banking association shall be otherwise
qualified and eligible under Section 6.11 hereof. The Indenture Trustee shall
provide the Rating Agencies and the Bond Insurer with prior written notice of
any such transaction.

     If at the time such successor or successors by merger, conversion or
consolidation to the Indenture Trustee shall succeed to the trusts created by
this Indenture and any of the Bonds shall have been authenticated but not
delivered, any such successor to the Indenture Trustee may adopt the certificate
of authentication of any predecessor trustee and deliver such Bonds so
authenticated; and if at that time any of the Bonds shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Bonds either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force which it is in the Bonds or in this Indenture provided
that the certificate of the Indenture Trustee shall have.

     Section 6.10 APPOINTMENT OF CO-INDENTURE TRUSTEE OR SEPARATE INDENTURE
TRUSTEE. (a) Notwithstanding any other provisions of this Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the Trust Estate may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, or separate
trustee or separate trustees, of all or any part of the Trust Estate, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Bondholders and the Bond Insurer, such title to the Trust Estate, or any part
hereof, and, subject to the other provisions of this Section, such powers,
duties, obligations, rights and trusts as the Indenture Trustee or the Bond
Insurer may consider necessary or desirable. No co-trustee or separate trustee
hereunder shall be required to meet the terms of eligibility as a successor
trustee under Section 6.11 hereof and notice to the Bond Insurer but not to the
Bondholders (unless a Bond Insurer Default exists, in which case notice will be
sent to the Bondholders) of the appointment of any co-trustee or separate
trustee shall be required under Section 6.08 hereof.

     (b) Every separate trustee and co-trustee shall, to the extent permitted by
law, be appointed and act subject to the following provisions and conditions:



                                       56

<PAGE>



               (i) all rights, powers, duties and obligations conferred or
     imposed upon the Indenture Trustee shall be conferred or imposed upon and
     exercised or performed by the Indenture Trustee and such separate trustee
     or co-trustee jointly (it being understood that such separate trustee or
     co-trustee is not authorized to act separately without the Indenture
     Trustee joining in such act), except to the extent that under any law of
     any jurisdiction in which any particular act or acts are to be performed
     the Indenture Trustee shall be incompetent or unqualified to perform such
     act or acts, in which event such rights, powers, duties and obligations
     (including the holding of title to the Trust Estate or any portion thereof
     in any such jurisdiction) shall be exercised and performed singly by such
     separate trustee or co-trustee, but solely at the direction of the
     Indenture Trustee;

               (ii) no trustee hereunder shall be personally liable by reason of
     any act or omission of any other trustee hereunder; and

               (iii) the Indenture Trustee may at any time accept the
     resignation of or remove any separate trustee or co-trustee.

     (c) Any notice, request or other writing given to the Indenture Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Indenture and
the conditions of this Article VI. Each separate trustee and co-trustee, upon
its acceptance of the trusts conferred, shall be vested with the estates or
property specified in its instrument of appointment, either jointly with the
Indenture Trustee or separately, as may be provided therein, subject to all the
provisions of this Indenture, specifically including every provision of this
Indenture relating to the conduct of, affecting the liability of, or affording
protection to, the Indenture Trustee. Every such instrument shall be filed with
the Indenture Trustee.

     (d) Any separate trustee or co-trustee may at any time constitute the
Indenture Trustee, its agent or attorney-in-fact with full power and authority,
to the extent not prohibited by law, to do any lawful act under or in respect of
this Indenture on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

     Section 6.11 ELIGIBILITY; DISQUALIFICATION. The Indenture Trustee shall at
all times satisfy the requirements of TIA ss. 310(a). The Indenture Trustee
shall have a combined capital and surplus of at least $50,000,000 as set forth
in its most recent published annual report of condition and it or its parent
shall have a long-term debt rating of Baa3 or better by Moody's and BBB or
better by Standard & Poor's. The Indenture Trustee shall comply with TIA ss.
310(b), including the optional provision permitted by the second sentence of TIA
ss. 310(b)(9); PROVIDED, HOWEVER, that there shall be excluded from the
operation of TIA ss. 310(b)(1) any indenture or indentures under which other
securities of the Issuer are outstanding if the requirements for such exclusion
set forth in TIA ss. 310(b)(1) are met.

     Section 6.12 PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUER. The
Indenture Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). An Indenture Trustee who has resigned or
been removed shall be subject to TIA ss. 311(a) to the extent indicated.

     Section 6.13 REPRESENTATIONS AND WARRANTIES. The Indenture Trustee hereby
represents that:

               (i) The Indenture Trustee is duly organized and validly existing

     (with or without notice or lapse of time) a default under, the articles of
     incorporation or bylaws of the Indenture Trustee or any agreement or other
     instrument to which the Indenture Trustee is a party or by which it is
     bound; and

               (iv) To the Indenture Trustee's knowledge, there are no
     proceedings or investigations pending or threatened before any court,
     regulatory body, administrative agency or other governmental
     instrumentality having jurisdiction over the Indenture Trustee or its
     properties: (A) asserting the invalidity of this Indenture (B) seeking to
     prevent the consummation of any of the transactions contemplated by this

     Trust Estate or, except as otherwise permitted or contemplated herein,
     terminate the lien of this Indenture on any property at any time subject
     hereto or deprive the Holder of any Bond of the security provided by the
     lien of this Indenture;

and PROVIDED, FURTHER, that such action shall not, as evidenced by an Opinion of
Counsel, cause the Issuer (if 100% of the Certificates are not owned by IMH
Assets Corp.) to be subject to an entity level tax.

     Any such action shall not adversely affect in any material respect the
interest of any Holder (other than a Holder who shall consent to such
supplemental indenture) as evidenced by an Opinion of Counsel (provided by the
Person requesting such supplemental indenture) delivered to the Indenture
Trustee.

     No supplemental indenture adverse to the interests of the Derivative
Contract Counterparty shall be entered into without the Derivative Contract
Counterparty's written consent.

     It shall not be necessary for any Act of Bondholders under this Section
9.02 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such Act shall approve the substance thereof.

     Promptly after the execution by the Issuer and the Indenture Trustee of any
supplemental indenture pursuant to this Section 9.02, the Indenture Trustee
shall mail to the Holders of the Bonds to which such amendment or supplemental
indenture relates a notice setting forth in general terms


                                       68

<PAGE>



the substance of such supplemental indenture. Any failure of the Indenture
Trustee to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental indenture.

     Section 9.03 EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or
permitting the additional trusts created by, any supplemental indenture
permitted by this Article IX or the modification thereby of the trusts created
by this Indenture, the Indenture Trustee shall be entitled to receive, and
subject to Sections 6.01 and 6.02 hereof, shall be fully protected in relying
upon, an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Indenture Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
that affects the Indenture Trustee's own rights, duties, liabilities or
immunities under this Indenture or otherwise.

     Section 9.04 EFFECT OF SUPPLEMENTAL INDENTURE. Upon the execution of any
supplemental indenture pursuant to the provisions hereof, this Indenture shall
be and shall be deemed to be modified and amended in accordance therewith with
respect to the Bonds affected thereby, and the respective rights, limitations of
rights, obligations, duties, liabilities and immunities under this Indenture of
the Indenture Trustee, the Issuer and the Holders of the Bonds shall thereafter
be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

     Section 9.05 CONFORMITY WITH TRUST INDENTURE ACT. Every amendment of this
Indenture and every supplemental indenture executed pursuant to this Article IX
shall conform to the requirements of the Trust Indenture Act as then in effect
so long as this Indenture shall then be qualified under the Trust Indenture Act.

     Section 9.06 REFERENCE IN BONDS TO SUPPLEMENTAL INDENTURES. Bonds
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX may, and if required by the Indenture Trustee shall,
bear a notation in form approved by the Indenture Trustee as to any matter
provided for in such supplemental indenture. If the Issuer or the Indenture
Trustee shall so determine, new Bonds so modified as to conform, in the opinion
of the Indenture Trustee and the Issuer, to any such supplemental indenture may
be prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Bonds.

                                    ARTICLE X

                                  Miscellaneous

     Section 10.01 COMPLIANCE CERTIFICATES AND OPINIONS, ETC. (a) Upon any
application or request by the Issuer to the Indenture Trustee to take any action
under any provision of this Indenture, the Issuer shall furnish to the Indenture
Trustee and to the Bond Insurer (i) an Officer's Certificate stating that all
conditions precedent, if any, provided for in this Indenture relating to the
proposed action have been complied with and (ii) an Opinion of Counsel stating
that in the opinion of such counsel all such conditions precedent, if any, have
been complied with, except that, in the case of any such application or request
as to which the furnishing of such documents is specifically required by any
provision of this Indenture, no additional certificate or opinion need be
furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant provided for in this Indenture shall include:

          (1) a statement that each signatory of such certificate or opinion has
     read or has caused to be read such covenant or condition and the
     definitions herein relating thereto;

          (2) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (3) a statement that, in the opinion of each such signatory, such
     signatory has made such examination or investigation as is necessary to
     enable such signatory to express an informed opinion as to whether or not
     such covenant or condition has been complied with;

          (4) a statement as to whether, in the opinion of each such signatory,
     such condition or covenant has been complied with; and

          (5) if the signatory of such certificate or opinion is required to be
     Independent, the statement required by the definition of the term
     "Independent".

     (b) (i) Prior to the deposit of any Collateral or other property or
securities with the Indenture Trustee that is to be made the basis for the
release of any property or securities subject to the lien of this Indenture, the
Issuer shall, in addition to any obligation imposed in Section 10.01 (a) or
elsewhere in this Indenture, furnish to the Indenture Trustee and the Bond
Insurer an Officer's Certificate certifying or stating the opinion of each
person signing such certificate as to the fair value (within 90 days prior to
such deposit) to the Issuer of the Collateral or other property or securities to
be so deposited and a report from a nationally recognized accounting firm
verifying such value.

               (ii) Whenever the Issuer is required to furnish to the Indenture
     Trustee and the Bond Insurer an Officer's Certificate certifying or stating
     the opinion of any signer thereof as to the matters described in clause (i)
     above, the Issuer shall also deliver to the Indenture Trustee an
     Independent Certificate from a nationally recognized accounting firm as to
     the same matters, if the fair value of the securities to be so deposited
     and of all other


                                       70

<PAGE>



     such securities made the basis of any such withdrawal or release since the
     commencement of the then current fiscal year of the Issuer, as set forth in
     the certificates delivered pursuant to clause (i) above and this clause
     (ii), is 10% or more of the Bond Principal Balances of the Bonds, but such
     a certificate need not be furnished with respect to any securities so
     deposited, if the fair value thereof as set forth in the related Officer's
     Certificate is less than $25,000 or less than one percent of the Bond
     Principal Balances of the Bonds.

               (iii) Whenever any property or securities are to be released from
     the lien of this Indenture, the Issuer shall also furnish to the Indenture
     Trustee and the Bond Insurer an Officer's Certificate certifying or stating
     the opinion of each person signing such certificate as to the fair value
     (within 90 days prior to such release) of the property or securities
     proposed to be released and stating that in the opinion of such person the
     proposed release will not impair the security under this Indenture in
     contravention of the provisions hereof.

               (iv) Whenever the Issuer is required to furnish to the Indenture
     Trustee and the Bond Insurer an Officer's Certificate certifying or stating
     the opinion of any signer thereof as to the matters described in clause
     (iii) above, the Issuer shall also furnish to the Indenture Trustee an
     Independent Certificate as to the same matters if the fair value of the
     property or securities and of all other property or securities released
     from the lien of this Indenture since the commencement of the then-current
     calendar year, as set forth in the certificates required by clause (iii)
     above and this clause (iv), equals 10% or more of the Bond Principal
     Balances of the Bonds, but such certificate need not be furnished in the
     case of any release of property or securities if the fair value thereof as
     set forth in the related Officer's Certificate is less than $25,000 or less
     than one percent of the then Bond Principal Balances of the Bonds.

     Section 10.02 FORM OF DOCUMENTS DELIVERED TO INDENTURE TRUSTEE. In any case
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters, and any such Person may certify or give an opinion as to
such matters in one or several documents.

     Any certificate or opinion of an Authorized Officer of the Issuer may be
based, insofar as it relates to legal matters, upon a certificate or opinion of,
or representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate of an Authorized Officer or Opinion of Counsel
may be based, insofar as it relates to factual matters, upon a certificate or
opinion of, or representations by, an officer or officers of the Seller or the
Issuer, stating that the information with respect to such factual matters is in
the possession of the Seller or the Issuer, unless such counsel knows, or in the
exercise of reasonable care should know, that the certificate or opinion or
representations with respect to such matters are erroneous.

     Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Indenture, they may, but need not, be consolidated and
form one instrument.

     Whenever in this Indenture, in connection with any application or
certificate or report to the Indenture Trustee, it is provided that the Issuer
shall deliver any document as a condition of the granting of such application,
or as evidence of the Issuer's compliance with any term hereof, it is intended
that the truth and accuracy, at the time of the granting of such application or
at the effective date of such certificate or report (as the case may be), of the
facts and opinions stated in such document shall in such case be conditions
precedent to the right of the Issuer to have such application granted or to the
sufficiency of such certificate or report. The foregoing shall not, however, be
construed to affect the Indenture Trustee's right to rely upon the truth and
accuracy of any statement or opinion contained in any such document as provided
in Article VI.

     Section 10.03 ACTS OF BONDHOLDERS. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Bondholders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Bondholders in person
or by agents duly appointed in writing; and except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
are delivered to the Indenture Trustee, and, where it is hereby expressly
required, to the Issuer. Such instrument or instruments (and the action embodied
therein and evidenced thereby) are herein sometimes referred to as the "Act" of
the Bondholders signing such instrument or instruments. Proof of execution of
any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 6.01
hereof) conclusive in favor of the Indenture Trustee and the Issuer, if made in
the manner provided in this Section 10.03 hereof.

     (b) The fact and date of the execution by any person of any such instrument
or writing may be proved in any manner that the Indenture Trustee deems
sufficient.

     (c) The ownership of Bonds shall be proved by the Bond Registrar.

     (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action by the Holder of any Bonds shall bind the Holder of every Bond
issued upon the registration thereof or in exchange therefor or in lieu thereof,
in respect of anything done, omitted or suffered to be done by the Indenture
Trustee or the Issuer in reliance thereon, whether or not notation of such
action is made upon such Bond.

     Section 10.04 NOTICES ETC., TO INDENTURE TRUSTEE ISSUER AND RATING
AGENCIES. Any request, demand, authorization, direction, notice, consent, waiver
or Act of Bondholders or other documents provided or permitted by this Indenture
shall be in writing and if such request, demand, authorization, direction,
notice, consent, waiver or act of Bondholders is to be made upon, given or
furnished to or filed with:

               (i) the Indenture Trustee by any Bondholder or by the Issuer
     shall be sufficient for every purpose hereunder if made, given, furnished
     or filed in writing to or with


                                       72

<PAGE>



     the Indenture Trustee at the Corporate Trust Office. The Indenture Trustee
     shall promptly transmit any notice received by it from the Bondholders to
     the Issuer; or

               (ii) the Issuer by the Indenture Trustee or by any Bondholder
     shall be sufficient for every purpose hereunder if in writing and mailed
     first-class, postage prepaid to the Issuer addressed to: Impac CMB Trust
     Series 2003-4, in care of Wilmington Trust Company, Rodney Square North,
     1100 North Market Street, Wilmington, Delaware 19990- 0001, Attention:
     Corporate Trust Administration, or at any other address previously
     furnished in writing to the Indenture Trustee by the Issuer. The Issuer
     shall promptly transmit any notice received by it from the Bondholders to
     the Indenture Trustee; or

               (iii) the Bond Insurer by the Issuer, the Indenture Trustee or by
     any Bondholders shall be sufficient for every purpose hereunder if in
     writing and mailed, first- class postage pre-paid, or personally delivered
     or telecopied to: Ambac Assurance Corporation, One State Street Plaza, New
     York, New York 10004, Attention: Consumer Asset-Backed Securities Group,
     Telephone: (212) 208-3394, Telecopier: (212) 363-1459. The Bond Insurer
     shall promptly transmit any notice received by it from the Issuer, the
     Indenture Trustee or the Bondholders to the Issuer or Indenture Trustee, as
     the case may be.

     Notices required to be given to the Rating Agencies by the Issuer, the
Indenture Trustee or the Owner Trustee shall be in writing, mailed first-class
postage pre-paid, to (i) in the case of Moody's, at the following address:
Moody's Investors Service, Inc., Residential Mortgage Monitoring Department, 99
Church Street, New York, New York 10007 and (ii) in the case of Standard &
Poor's, at the following address: Standard & Poor's, 55 Water Street, 41st
Floor, New York, New York 10041, Attention of Asset Backed Surveillance
Department; or as to each of the foregoing, at such other address as shall be
designated by written notice to the other parties.

     Section 10.05 NOTICES TO BONDHOLDERS; WAIVER. Where this Indenture provides
for notice to Bondholders of any event, such notice shall be sufficiently given
(unless otherwise herein expressly provided) if in writing and mailed,
first-class, postage prepaid to each Bondholder affected by such event, at such
Person's address as it appears on the Bond Register, not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice. In any case where notice to Bondholders is given by mail, neither the
failure to mail such notice nor any defect in any notice so mailed to any
particular Bondholder shall affect the sufficiency of such notice with respect
to other Bondholders, and any notice that is mailed in the manner herein
provided shall conclusively be presumed to have been duly given regardless of
whether such notice is in fact actually received.

     Where this Indenture provides for notice in any manner, such notice may be
waived in writing by any Person entitled to receive such notice, either before
or after the event, and such waiver shall be the equivalent of such notice.
Waivers of notice by Bondholders shall be filed with the Indenture Trustee but
such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such a waiver.

     In case, by reason of the suspension of regular mail service as a result of
a strike, work stoppage or similar activity, it shall be impractical to mail
notice of any event to Bondholders when such notice is required to be given
pursuant to any provision of this Indenture, then any manner of


                                       73

<PAGE>



giving such notice as shall be satisfactory to the Indenture Trustee shall be
deemed to be a sufficient giving of such notice.

     Where this Indenture provides for notice to the Rating Agencies, failure to
give such notice shall not affect any other rights or obligations created
hereunder, and shall not under any circumstance constitute an Event of Default.

     Section 10.06 CONFLICT WITH TRUST INDENTURE ACT. If any provision hereof
limits, qualifies or conflicts with another provision hereof that is required to
be included in this Indenture by any of the provisions of the Trust Indenture
Act, such required provision shall control.

     The provisions of TIA ss.ss. 310 through 317 that impose duties on any
Person (including the provisions automatically deemed included herein unless
expressly excluded by this Indenture) are a part of and govern this Indenture,
whether or not physically contained herein.

     Section 10.07 EFFECT OF HEADINGS. The Article and Section headings herein
are for convenience only and shall not affect the construction hereof.

     Section 10.08 SUCCESSORS AND ASSIGNS. All covenants and agreements in this
Indenture and the Bonds by the Issuer shall bind its successors and assigns,
whether so expressed or not. All agreements of the Indenture Trustee in this
Indenture shall bind its successors, co-trustees and agents.

     Section 10.09 SEPARABILITY. In case any provision in this Indenture or in
the Bonds shall be invalid, illegal or unenforceable, the validity, legality,
and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby.

     Section 10.10 BENEFITS OF INDENTURE. The Bond Insurer and its successors
and assigns shall be a third-party beneficiary to the provisions of this
Indenture. To the extent that this Indenture confers upon or gives or grants to
the Bond Insurer any right, remedy or claim under or by reason of this
Indenture, the Bond Insurer may enforce any such right, remedy or claim
conferred, given or granted hereunder. Nothing in this Indenture or in the
Bonds, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Bondholders and the Bond Insurer,
any benefit or any legal or equitable right, remedy or claim under this
Indenture.

     Section 10.11 LEGAL HOLIDAYS. In any case where the date on which any
payment is due shall not be a Business Day, then (notwithstanding any other
provision of the Bonds or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

     Section 10.12 GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS, AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE
PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.


                                       74

     Section 10.13 COUNTERPARTS. This Indenture may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but
all such counterparts shall together constitute but one and the same instrument.

     Section 10.14 RECORDING OF INDENTURE. If this Indenture is subject to
recording in any appropriate public recording offices, such recording is to be
effected by the Issuer and at its expense accompanied by an Opinion of Counsel
at its expense (which may be counsel to the Indenture Trustee or any other
counsel reasonably acceptable to the Indenture Trustee) to the effect that such
recording is necessary either for the protection of the Bondholders or any other
Person secured hereunder or for the enforcement of any right or remedy granted
to the Indenture Trustee under this Indenture.

     Section 10.15 ISSUER OBLIGATION. No recourse may be taken, directly or
indirectly, with respect to the obligations of the Issuer, the Owner Trustee or
the Indenture Trustee on the Bonds or under this Indenture or any certificate or
other writing delivered in connection herewith or therewith, against (i) the
Indenture Trustee or the Owner Trustee in its individual capacity, (ii) any
owner of a beneficial interest in the Issuer or (iii) any partner, owner,
beneficiary, agent, officer, director, employee or agent of the Indenture
Trustee or the Owner Trustee in its individual capacity, any holder of a
beneficial interest in the Issuer, the Owner Trustee or the Indenture Trustee or
of any successor or assign of the Indenture Trustee or the Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits
of, the terms and provisions of Article VI, VII and VIII of the Trust Agreement.

     Section 10.16 NO PETITION. The Indenture Trustee, by entering into this
Indenture, and each Bondholder, by accepting a Bond, hereby covenant and agree
that they will not at any time prior to one year from the date of termination
hereof, institute against the Depositor or the Issuer, or join in any
institution against the Depositor or the Issuer of, any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceedings, or other
proceedings under any United States federal or state bankruptcy or similar law
in connection with any obligations relating to the Bonds, this Indenture or any
of the Basic Documents.

     Section 10.17 INSPECTION. The Issuer agrees that, at its expense, on
reasonable prior notice, it shall permit any representative of the Indenture
Trustee and the Bond Insurer, during the Issuer's normal business hours, to
examine all the books of account, records, reports and other papers of the
Issuer, to make copies and extracts therefrom, to cause such books to be audited
by Independent certified public accountants, and to discuss the Issuer's
affairs, finances and accounts with the Issuer's officers, employees, and
Independent certified public accountants, all at such reasonable times and as
often as may be reasonably requested. The Indenture Trustee and the Bond Insurer
shall cause its representatives to hold in confidence all such information
except to the extent disclosure may be required by law (and all reasonable
applications for confidential treatment are unavailing)


                                       75

<PAGE>



and except to the extent that the Indenture Trustee or the Bond Insurer may
reasonably determine that such disclosure is consistent with its obligations
hereunder.

     On this 31st day of March, 2003, before me personally appeared James F.
Noriega to me known, who being by me duly sworn, did depose and say, that he is
the Associate of the Indenture Trustee, one of the corporations described in and

     Impac CMB Trust Series 2003-4 (the "Issuer"), a Delaware statutory trust,
for value received, hereby promises to pay to Cede & Co. or registered assigns,
the principal sum of ($_________________) in monthly installments on the
twenty-fifth day of each month or, if such day is not a Business Day, the next

2033][September 2005] (the "Final Scheduled Payment Date") and to pay interest
on the [Bond Principal Balance][Notional Amount] of this Bond (this "Bond")
outstanding from time to time as provided below.

     This Bond is one of a duly authorized issue of the Issuer's Collateralized
Asset-Backed Bonds, Series 2003-4 (the "Bonds"), issued under an Indenture dated
as of March 31, 2003 (the "Indenture"), between the Issuer and Deutsche Bank
National Trust Company, as indenture trustee (the "Indenture Trustee", which
term includes any successor Indenture Trustee under the Indenture), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights thereunder of the Issuer, the Indenture
Trustee, and the Holders of the Bonds and the terms upon which the Bonds are to
be authenticated and delivered. All terms used in this Bond which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.

     [Ambac Assurance Corporation (the "Bond Insurer"), in consideration of the
payment of the premium and subject to the terms of the bond insurance policy
(the "Bond Insurance Policy") issued thereby, has unconditionally and
irrevocably guaranteed the payment of the Group 1 and Group 2 Insured Amount
with respect to the Class 1-A-1 Bonds and Class 2-A-1 Bonds, respectively, with
respect to each Payment Date. Such Bond Insurance Policy will not cover any
Prepayment Interest Shortfalls, Relief Act Shortfalls or Basis Risk Shortfall
Carry- Forward Amount.]

     Payments of [principal and] interest on this Bond will be made on each
Payment Date to the Bondholder of record as of the related Record Date. [The
"Bond Principal Balance" of a Bond as of any date of determination is equal to
the initial Bond Principal Balance thereof, reduced by the aggregate of all
amounts previously paid with respect to such Bond on account of principal and
the


                                      A-1-2

aggregate amount of cumulative Realized Losses allocated to such Bond on all
prior Payment Dates.][The "Notional Amount" of this Bond, immediately prior to
the related Payment Date, for the April 2003 Payment Date through the March 2004
Payment Date is $37,500,695, for the April 2004 Payment Date through the

     The [principal of, and] interest on[,] this Bond [are][is] due and payable
as described in the Indenture, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. All payments made by the Issuer with respect to this Bond shall
be equal to this Bond's pro rata share of the aggregate payments on all Class
[_-A-_] Bonds as described above, and shall be applied as [between] interest
[and principal] as provided in the Indenture. [In addition, any payments
received by the Indenture Trustee in respect of the Seller Guarantee shall be
paid to the Holders of this Bond pursuant to Section 3.32 of the Indenture.]

     All [principal and] interest accrued on the Bonds, if not previously paid,
will become finally due and payable at the Final Scheduled Payment Date.

     The Bonds, other than the Class 3-A-IO Bonds, are subject to redemption in
whole, but not in part, by the Majority Certificateholder on any Payment Date on
or after the earlier of (i) the Payment Date on which the aggregate Stated
Principal Balance of the Mortgage Loans as of the end of the prior Due Period is
less than or equal to 25% of the aggregate Stated Principal Balance of the
Mortgage Loans as of Cut-off Date and (ii) the Payment Date in April 2013.

     The Issuer shall not be liable upon the indebtedness evidenced by the Bonds
except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Bonds. The assets included in the
Trust Estate will be the sole source of payments on the Class [_-A- _] Bonds,
and each Holder hereof, by its acceptance of this Bond, agrees that (i) such
Bond will be limited in right of payment to amounts available from the Trust
Estate as provided in the Indenture and (ii) such Holder shall have no recourse
to the Issuer, the Owner Trustee, the Indenture Trustee, IMH Assets Corp., Impac
Mortgage Holdings, Inc., the Master Servicer or any of their respective
affiliates, or to the assets of any of the foregoing entities, except the assets
of the Issuer pledged to secure the Class [_-A-_] Bonds pursuant to the
Indenture and the rights conveyed to the Issuer under the Indenture.

     Any payment [of principal or] interest payable on this Bond which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Bond is registered at the close of business on the Record Date
for such Payment Date by check mailed to such person's address as it appears in
the Bond Register on such Record Date, except for the final installment of
[principal and] interest payable with respect to such Bond, which shall be
payable as provided below. Notwithstanding the foregoing, upon written request
with appropriate instructions by the Holder of this Bond delivered to the
Indenture Trustee at least five Business Days prior to the Record Date, any
payment of [principal or] interest, other than the final installment of
[principal or] interest, shall be made by wire transfer to an account in the
United States designated by such Holder. All [scheduled] reductions in the
[Notional Amount] [principal amount] of a Bond (or one or more predecessor
Bonds) [effected by payments of principal made on any Payment Date] shall be
binding upon all


                                      A-1-3

<PAGE>



Holders of this Bond and of any bond issued upon the registration of transfer
thereof or in exchange therefor or in lieu thereof, whether or not such payment
is noted on such Bond. The final payment of this Bond shall be payable upon
presentation and surrender thereof on or after the Payment Date thereof at the
Corporate Trust Office or the office or agency of the Issuer maintained by it
for such purpose pursuant to Section 3.02 of the Indenture.

     Subject to the foregoing provisions, each Bond delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Bond shall carry the right to unpaid [principal and] interest that were
carried by such other Bond.

     If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Bonds, the Bonds may become or be declared due
and payable in the manner and with the effect provided in the Indenture. If any
such acceleration of maturity occurs [prior to the payment of the entire unpaid
Bond Principal Balance of the Bonds], the amount payable to the Holder of this
Bond will be equal to the [sum of the unpaid Bond Principal Balance of the
Bonds, together with] accrued and unpaid interest [thereon][on the Notional
Amount] as described in the Indenture. The Indenture provides that,
notwithstanding the acceleration of the maturity of the Bonds, under certain
circumstances specified therein, all amounts collected as proceeds of the Trust
Estate securing the Bonds or otherwise shall continue to be applied to payments
of [principal of and] interest on the Bonds as if they had not been declared due
and payable.

     The failure to pay any Unpaid Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     The Holder of this Bond or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Bond with Plan
Assets or (2) (A) the acquisition, holding and transfer of a Bond will not give
rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code as a result of the Issuer, the Seller, the Depositor, the
Underwriters, the Owner Trustee, the Indenture Trustee, the Master Servicer, any
Subservicer, any other servicer, any administrator, any provider of credit
support, any owner of the Certificates, or any of their Affiliates being a
"Party in Interest" (within the meaning of ERISA) or Disqualified Person (within
the meaning of the Code) with respect to such Holder or Beneficial Owner that is
a Plan and (B) the Bonds are rated investment grade or better and such person
believes that the Bonds are properly treated as indebtedness without substantial
equity features for purposes of the DOL Regulations, and agrees to so treat the
Bonds. Alternatively, regardless of the rating of the Bonds, such person may
provide the Indenture Trustee and the Owner Trustee with an opinion of counsel,
which opinion of counsel will not be at the expense of the Issuer, the Seller,
any Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer
or any successor servicer which opines that the acquisition, holding and
transfer of such Bond or interest therein is permissible under applicable law,
will not constitute or result in a non-exempt prohibited transaction under ERISA
or Section 4975 of the Code and will not subject the Issuer, the Seller, the
Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master
Servicer or any successor servicer to any obligation in addition to those
undertaken in the Indenture.

     Pursuant to the Indenture, unless a Bond Insurer Default (as defined in the
Indenture) exists (i) the Bond Insurer shall be deemed to be the holder of the
Class [_-A-_] Bonds for certain purposes specified in the Indenture (other than
with respect to payment on the Class [_-A-_] Bonds), and will be entitled to
exercise all rights of the Bondholders thereunder, including the rights of
Bondholders relating to the occurrence of, and the remedies with respect to, an
Event of Default, without the consent of such Bondholders, and (ii) the Trustee
may take actions which would otherwise be at its option or within its
discretion, including actions relating to the occurrence of, and the remedies
with respect to, an Event of Default, only at the direction, or with the
consent, of the Bond Insurer.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Bond may be registered on the Bond Register of the
Issuer. Upon surrender for registration of transfer of, or presentation of a
written instrument of transfer for, this Bond at the office or agency designated
by the Issuer pursuant to the Indenture, accompanied by proper instruments of
assignment in form satisfactory to the Indenture Trustee, one or more new Bonds
of any authorized denominations and of a like aggregate initial Bond Principal
Balance, will be issued to the designated transferee or transferees.

     Prior to the due presentment for registration of transfer of this Bond, the
Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture
Trustee may treat the Person in whose name this Bond is registered as the owner
of such Bond (i) on the applicable Record Date for the purpose of making
payments and interest of such Bond, and (ii) on any other date for all other
purposes whatsoever, as the owner hereof, whether or not this Bond be overdue,
and neither the Issuer, the Indenture Trustee nor any such agent of the Issuer
or the Indenture Trustee shall be affected by notice to the contrary.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Bond Insurer and the Holders of a
majority of all Bonds at the time outstanding. The Indenture also contains
provisions permitting (i) the Bond Insurer or (ii) if the Bond Insurer defaults,
the Holders of Bonds representing specified percentages of the aggregate Bond
Principal Balance and Notional Amount of the Bonds on behalf of the Holders of
all the Bonds, to waive any past Default under the Indenture and its
consequences. Any such waiver by the Holder, at the time of the giving thereof,
of this Bond (or any one or more predecessor Bonds) shall bind the Holder of
every Bond issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not notation of such consent or waiver is made
upon such Bond. The Indenture also permits the Issuer and the Indenture Trustee
to amend or waive certain terms and conditions set forth in the Indenture
without the consent of the Holders of the Bonds issued thereunder.

     Initially, the Bonds will be registered in the name of CEDE & Co. as
nominee of DTC, acting in its capacity as the Depository for the Bonds. The
Bonds will be delivered by the clearing agency in denominations as provided in
the Indenture and subject to certain limitations therein set forth. The Bonds
are exchangeable for a like aggregate initial [Bond Principal Balance][Notional
Amount] of Bonds of different authorized denominations, as requested by the
Holder surrendering same.

amounts previously paid with respect to such Bond on account of principal and
the aggregate amount of cumulative Realized Losses allocated to such Bond on all
prior Payment Dates.

     The principal of, and interest on, this Bond are due and payable as
described in the Indenture, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. All payments made by the Issuer with respect to this Bond shall
be equal to this Bond's pro rata share of the aggregate payments on all Class
3-M-[_] Bonds as described above, and shall be applied as between interest and
principal as provided in the Indenture.

     All principal and interest accrued on the Bonds, if not previously paid,
will become finally due and payable at the Final Scheduled Payment Date.

     The Bonds are subject to redemption in whole, but not in part, by the
Majority Certificateholder on any Payment Date on or after the earlier of (i)
the Payment Date on which the aggregate Stated Principal Balance of the Mortgage
Loans is less than or equal to 25% of aggregate Stated Principal Balance of the
Mortgage Loans as of Cut-off Date and (ii) the Payment Date in April 2013.

     The Issuer shall not be liable upon the indebtedness evidenced by the Bonds
except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Bonds. The assets included in the
Trust Estate will be the sole source of payments on the Class 3-M- [_] Bonds,
and each Holder hereof, by its acceptance of this Bond, agrees that (i) such
Bond will be limited in right of payment to amounts available from the Trust
Estate as provided in the Indenture and (ii) such Holder shall have no recourse
to the Issuer, the Owner Trustee, the Indenture Trustee, IMH Assets Corp., Impac
Mortgage Holdings, Inc., the Master Servicer or any of their respective
affiliates, or to the assets of any of the foregoing entities, except the assets
of the Issuer pledged to secure the Class 3-M-[_] Bonds pursuant to the
Indenture and the rights conveyed to the Issuer under the Indenture.

     Any payment of principal or interest payable on this Bond which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Bond is registered at the close of business on the Record Date
for such Payment Date by check mailed to such person's address as it appears in
the Bond Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Bond, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Bond delivered to the Indenture
Trustee at least five Business Days prior to the Record Date, any payment of
principal or interest, other than the final installment of principal or
interest, shall be made by wire transfer to an account in the United States
designated by such Holder. All reductions in the principal amount of a Bond (or
one or more predecessor Bonds) effected by payments of principal made on any
Payment Date shall be binding upon all Holders of this Bond and of any bond
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, whether or not such payment is noted on such Bond. The final
payment of this Bond shall be payable upon presentation and surrender thereof on
or after the Payment Date thereof at the Corporate Trust Office or the office or
agency of the Issuer maintained by it for such purpose pursuant to Section 3.02
of the Indenture.

     Subject to the foregoing provisions, each Bond delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Bond shall carry the right to unpaid principal and interest that were
carried by such other Bond.

     If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Bonds, the Bonds may become or be declared due
and payable in the manner and with the effect provided in the Indenture. If any
such acceleration of maturity occurs prior to the payment of the entire unpaid
Bond Principal Balance of the Bonds, the amount payable to the Holder of this
Bond will be equal to the sum of the unpaid Bond Principal Balance of the Bonds,
together with accrued and unpaid interest thereon as described in the Indenture.
The Indenture provides that, notwithstanding the acceleration of the maturity of
the Bonds, under certain circumstances specified therein, all amounts collected
as proceeds of the Trust Estate securing the Bonds or otherwise shall


                                      A-2-3

<PAGE>



continue to be applied to payments of principal of and interest on the Bonds as
if they had not been declared due and payable.

     The failure to pay any Unpaid Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     The Holder of this Bond or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Bond with Plan
Assets or (2) (A) the acquisition, holding and transfer of a Bond will not give
rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code as a result of the Issuer, the Seller, the Depositor, the
Underwriters, the Owner Trustee, the Indenture Trustee, the Master Servicer, any
Subservicer, any other servicer, any administrator, any provider of credit
support, any owner of the Certificates, or any of their Affiliates being a
"Party in Interest" (within the meaning of ERISA) or Disqualified Person (within
the meaning of the Code) with respect to such Holder or Beneficial Owner that is
a Plan and (B) the Bonds are rated investment grade or better and such person
believes that the Bonds are properly treated as indebtedness without substantial
equity features for purposes of the DOL Regulations, and agrees to so treat the
Bonds. Alternatively, regardless of the rating of the Bonds, such person may
provide the Indenture Trustee and the Owner Trustee with an opinion of counsel,
which opinion of counsel will not be at the expense of the Issuer, the Seller,
any Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer
or any successor servicer which opines that the acquisition, holding and
transfer of such Bond or interest therein is permissible under applicable law,
will not constitute or result in a non-exempt prohibited transaction under ERISA
or Section 4975 of the Code and will not subject the Issuer, the Seller, the
Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master
Servicer or any successor servicer to any obligation in addition to those
undertaken in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Bond may be registered on the Bond Register of the
Issuer. Upon surrender for registration of transfer of, or presentation of a
written instrument of transfer for, this Bond at the office or agency designated
by the Issuer pursuant to the Indenture, accompanied by proper instruments of
assignment in form satisfactory to the Indenture Trustee, one or more new Bonds
of any authorized denominations and of a like aggregate initial Bond Principal
Balance, will be issued to the designated transferee or transferees.

     Prior to the due presentment for registration of transfer of this Bond, the
Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture
Trustee may treat the Person in whose name this Bond is registered as the owner
of such Bond (i) on the applicable Record Date for the purpose of making
payments and interest of such Bond, and (ii) on any other date for all other
purposes whatsoever, as the owner hereof, whether or not this Bond be overdue,
and neither the Issuer, the Indenture Trustee nor any such agent of the Issuer
or the Indenture Trustee shall be affected by notice to the contrary.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the Indenture at any
time by the Issuer with the consent of the Bond Insurer and the


                                      A-2-4

<PAGE>



Holders of a majority of all Bonds at the time outstanding. The Indenture also
contains provisions permitting the Holders of Bonds representing specified
percentages of the aggregate Bond Principal Balance of the Bonds on behalf of
the Holders of all the Bonds, to waive any past Default under the Indenture and
its consequences. Any such waiver by the Holder, at the time of the giving
thereof, of this Bond (or any one or more predecessor Bonds) shall bind the
Holder of every Bond issued upon the registration of transfer hereof or in
exchange hereof or in lieu hereof, whether or not notation of such consent or
waiver is made upon such Bond. The Indenture also permits the Issuer and the
Indenture Trustee to amend or waive certain terms and conditions set forth in
the Indenture without the consent of the Holders of the Bonds issued thereunder.

     Initially, the Bonds will be registered in the name of Cede & Co. as
nominee of DTC, acting in its capacity as the Depository for the Bonds. The
Bonds will be delivered by the clearing agency in denominations as provided in
the Indenture and subject to certain limitations therein set forth. The Bonds
are exchangeable for a like aggregate initial Bond Principal Balance of Bonds of
different authorized denominations, as requested by the Holder surrendering
same.

     Unless the Certificate of Authentication hereon has been executed by the
Indenture Trustee by manual signature, this Bond shall not be entitled to any
benefit under the Indenture, or be valid or obligatory for any purpose.

     AS PROVIDED IN THE INDENTURE, THIS BOND AND THE INDENTURE CREATING THIS
BOND SHALL BE CONSTRUED IN ACCORDANCE WITH, AND GOVERNED BY, THE LAWS OF THE
STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED THEREIN.

for value received, hereby promises to pay to Cede & Co. or registered assigns,
the principal sum of ______________________________ ($___________) in monthly

[July][October] 2033 (the "Final Scheduled Payment Date") and to pay interest on
the Bond Principal Balance of this Bond (this "Bond") outstanding from time to

     This Bond is one of a duly authorized issue of the Issuer's Collateralized

as of March 31, 2003 (the "Indenture"), between the Issuer and Deutsche Bank

Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights thereunder of the Issuer, the Indenture
Trustee, and the Holders of the Bonds and the terms upon which the Bonds are to
be authenticated and delivered. All terms used in this Bond which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.

     Payments of principal and interest on this Bond will be made on each
Payment Date to the Bondholder of record as of the related Record Date. The
"Bond Principal Balance" of a Bond as of any date of determination is equal to
the initial Bond Principal Balance thereof, reduced by the aggregate of all

prior Payment Dates.

     The principal of, and interest on, this Bond are due and payable as

Majority Certificateholder on any Payment Date on or after the earlier of (i)
the Payment Date on which the aggregate Stated Principal Balance of the Mortgage
Loans is less than or equal to 25% of aggregate Stated Principal Balance of the
Mortgage Loans as of Cut-off Date and (ii) the Payment Date in April 2013.

     The Issuer shall not be liable upon the indebtedness evidenced by the Bonds
except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Bonds. The assets included in the
Trust Estate will be the sole source of payments on the Class [_]- B-1 Bonds,
and each Holder hereof, by its acceptance of this Bond, agrees that (i) such
Bond will be limited in right of payment to amounts available from the Trust

affiliates, or to the assets of any of the foregoing entities, except the assets
of the Issuer pledged to secure the Class [_]-B-1 Bonds pursuant to the
Indenture and the rights conveyed to the Issuer under the Indenture.

     Any payment of principal or interest payable on this Bond which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Bond is registered at the close of business on the Record Date
for such Payment Date by check mailed to such person's address as it appears in
the Bond Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Bond, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Bond delivered to the Indenture
Trustee at least five Business Days prior to the Record Date, any payment of
principal or interest, other than the final installment of principal or
interest, shall be made by wire transfer to an account in the United States
designated by such Holder. All reductions in the principal amount of a Bond (or
one or more predecessor Bonds) effected by payments of principal made on any
Payment Date shall be binding upon all Holders of this Bond and of any bond
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, whether or not such payment is noted on such Bond. The final
payment of this Bond shall be payable upon presentation and surrender thereof on
or after the Payment Date thereof at the Corporate Trust Office or the office or
agency of the Issuer maintained by it for such purpose pursuant to Section 3.02
of the Indenture.

     Subject to the foregoing provisions, each Bond delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Bond shall carry the right to unpaid principal and interest that were
carried by such other Bond.

     If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Bonds, the Bonds may become or be declared due
and payable in the manner and with the effect provided in the Indenture. If any
such acceleration of maturity occurs prior to the payment of the entire unpaid
Bond Principal Balance of the Bonds, the amount payable to the Holder of this
Bond will be equal to the sum of the unpaid Bond Principal Balance of the Bonds,
together with accrued and unpaid interest thereon as described in the Indenture.
The Indenture provides that, notwithstanding the acceleration of the maturity of
the Bonds, under certain circumstances specified therein, all amounts collected
as proceeds of the Trust Estate securing the Bonds or otherwise shall


                                      A-3-3

if they had not been declared due and payable.

     The failure to pay any Unpaid Interest Shortfall at any time when funds are
not available to make such payment as provided in the Indenture shall not
constitute an Event of Default under the Indenture.

     The Holder of this Bond or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Bond with Plan

Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master
Servicer or any successor servicer to any obligation in addition to those
undertaken in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Bond may be registered on the Bond Register of the
Issuer. Upon surrender for registration of transfer of, or presentation of a
written instrument of transfer for, this Bond at the office or agency designated

assignment in form satisfactory to the Indenture Trustee, one or more new Bonds
of any authorized denominations and of a like aggregate initial Bond Principal

         A Trigger Event is in effect with respect to any Payment Date with
respect to the Group 2 Loans if, in the case of any Payment Date after the 36th
Payment Date, the three month average of the aggregate principal balance of
Group 2 Loans that are 60 or more days delinquent (including for this purpose
any such Mortgage Loans in bankruptcy or foreclosure and Group 2 Loans with

For purposes of the foregoing calculations, a Mortgage Loan is considered "60
days" and "90 days" delinquent if a payment due on the first day of a month has
not been received by the second day of the second following month and third
following month, respectively.
