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

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

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

         Notes 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 Notes or did not hold
such offices at the date of such Notes.

         The Indenture Trustee shall upon Issuer Request authenticate and
deliver each Class of Notes for original issue in an aggregate initial principal
amount equal to the Initial Note Principal Balance for such Class of Notes.

         Each of the Notes shall be dated the date of its authentication. The

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

         No Note shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Note 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 Note shall be conclusive
evidence, and the only evidence, that such Note has been duly authenticated and
delivered hereunder.

         Section 2.03 ACCEPTANCE OF MORTGAGE LOANS BY INDENTURE TRUSTEE. (a) The
Indenture Trustee shall cause the Custodian as agent for the Indenture Trustee
to acknowledge 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 Purchase Agreement, and to declare
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
agent for the Indenture Trustee in trust for the use and benefit of all present
and future Holders of the Notes. No later than the Closing Date, with respect to
the Mortgage Loans (or, with respect to any Eligible Substitute Mortgage Loan,


                                        4

<PAGE>



within 5 days after the receipt by the Custodian as agent for the Indenture
Trustee thereof and, with respect to any documents received after the Closing
Date, promptly thereafter), the Indenture Trustee shall cause the Custodian, as
agent for the Indenture Trustee, to agree, for the benefit of the Noteholders,
to review each Mortgage File delivered to it and to execute and deliver, or to
cause to be executed and delivered, to the Seller, the Indenture Trustee and the
Master Servicer an Initial Certification in the form annexed to the Custodial
Agreement as Exhibit One. In conducting such review, the Indenture Trustee shall
cause the Custodian, as agent for the Indenture Trustee, to ascertain whether
all required documents described in Section 2.1(b)(i) to (v) of the Mortgage
Loan Purchase Agreement have been executed and received and whether those
documents relate, 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)(vi) of such section, the
Custodian's obligations shall extend only to documents actually delivered
pursuant to such subclause). In performing any such review, the Custodian as
agent for 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 Custodian as agent for 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
Custodian as agent for the Indenture Trustee shall promptly notify the Seller
and the Indenture Trustee of such finding.

         (b) No later than 180 days after the Closing Date, the Custodian as
agent for the Indenture Trustee will review, for the benefit of the Noteholders,
the Mortgage Files and will execute and deliver or cause to be executed and
delivered to the Seller, the Master Servicer and the Indenture Trustee, a Final
Certification in the form annexed to the Custodial Agreement as Exhibit Two. In
conducting such review, the Custodian as agent for the Indenture Trustee will
ascertain whether an original of each document described in subclauses
(b)(ii)-(iv) of Section 2.1 of (i) the Mortgage Loan Purchase Agreement,
required to be recorded has been returned from the recording office with
evidence of recording thereon or a certified copy has been obtained from the
recording office. If the Custodian as agent for the Indenture Trustee finds any
document constituting part of the Mortgage File has not been received, or to be
unrelated, to the Mortgage Loans identified in Exhibit B to this Indenture or to
appear defective on its face, the Custodian as agent for the Indenture Trustee
shall promptly notify the Seller and the Indenture Trustee.

         (c) Upon deposit by the Seller of the Repurchase Price in the Payment
Account, the Indenture Trustee shall cause the Custodian to release to the
Seller or the Master Servicer, as applicable, the related Mortgage File and the
Indenture Trustee shall execute and deliver all instruments of transfer or
assignment, without recourse, furnished to it by the Seller or the Master
Servicer, as applicable, as are necessary to vest in the Seller or the Master
Servicer, as applicable, title to and rights under the related Mortgage Loan.
Such purchase shall be deemed to have occurred on the date on which the deposit
of the Repurchase Price in the Payment Account was received by the Indenture
Trustee. The Custodian as agent for the Indenture Trustee shall amend the
applicable Mortgage Loan Schedule to reflect such repurchase and shall promptly
notify the Master Servicer and the Indenture Trustee of such amendment.

The Indenture Trustee shall establish and maintain an Eligible Account (the

Indenture Trustee with respect to the Mortgage Loans. The Indenture Trustee

where notices and demands to or upon the Issuer in respect of the Notes and this
Indenture may be served. The Issuer hereby initially appoints the Indenture
Trustee to serve as its agent for the foregoing purposes. If at any time the

Agent shall be released from all further liability with respect to such money.

held by the Indenture Trustee or any Paying Agent in trust for the payment of
any amount due with respect to any Note 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 Note 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
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 Notes 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).

existence, rights and franchises as a statutory trust under the laws of the

and franchises under the laws of such other jurisdiction) and will obtain and

Indenture Trustee that:

                  (i) This Indenture creates a valid and continuing security
interest (as defined in the applicable UCC) in the Collateral in favor of the
Indenture Trustee, which security interest is prior to all other liens, and is
enforceable as such as against creditors of and purchasers from the Issuer.

                  (ii) The Collateral constitutes "deposit accounts" or
"instruments," as applicable, within the meaning of the applicable UCC.

                  (iii) The Issuer owns and has good and marketable title to the
Collateral, free and clear of any lien, claim or encumbrance of any Person.

Indenture Trustee to become the account holder of the Collateral.



                                       22

<PAGE>



                  (v) Other than the security interest granted to the Indenture
Trustee pursuant to this Indenture, the Issuer has not pledged, assigned, sold,
granted a security interest in, or otherwise conveyed any of the Collateral.

                  (vi) The Collateral is not in the name of any Person other
than the Issuer or the Indenture Trustee. The Issuer has not consented to the
bank maintaining the Collateral to comply with instructions of any Person other
than the Indenture Trustee.

         (b) With respect to that portion of the Collateral described in clauses
(d) and (e), the Issuer represents to the Indenture Trustee that:

                  (i) This Indenture creates a valid and continuing security
interest (as defined in the applicable UCC) in the Collateral in favor of the
Indenture Trustee, which security interest is prior to all other liens, and is
enforceable as such as against creditors of and purchasers from the Issuer.

                  (ii) The Collateral constitutes "general intangibles" within

perfected by filing, the Issuer has not authorized the filing of, and is not
aware of any financing statements against, the Issuer, that include a
description of collateral covering such Collateral, other than any financing
statement relating to the security interest granted to the Indenture Trustee
hereunder or that has been terminated. The Issuer is not aware of any judgment
or tax lien filings against the Issuer.

         (d) The Issuer has caused or will have caused, within ten days, the
filing of all appropriate financing statements in the proper filing office in
the appropriate jurisdictions under applicable law in order to perfect the
security interest in all Collateral granted to the Indenture Trustee hereunder
in which a security interest may be perfected by filing. Any financing statement
that is filed in connection with this Section 3.28 shall contain a statement
that a purchase or security interest in any collateral described therein will
violate the rights of the secured party named in such financing statement.

         (e) The foregoing representations may not be waived and shall survive
the issuance of the Notes.

         Section 3.29 ALLOCATION OF REALIZED LOSSES. (a) Any Realized Losses on
the Mortgage Loans will be allocated or covered on any Payment Date as follows:
FIRST, to the related Net Monthly Excess Cashflow, by an increase in the related
Overcollateralization Increase Amount for that


                                       23

<PAGE>



Payment Date as provided in Section 3.05 of this Indenture; SECOND, to the
non-related Net Monthly Excess Cashflow, to the extent described in Section 3.05
of this Indenture above; THIRD, in reduction of the Overcollateralized Amount
for related and non-related Loan Groups, until reduced to zero (meaning, no
losses will be allocated to the Class M Notes until the aggregate Note Principal
Balance of the Notes equals the aggregate Stated Principal Balance of the
Mortgage Loans); and FOURTH, (i) if such Realized Loss is on a Group I Loan, to
the Class I-M-3, Class I-M-2 and Class I-M- 1 Notes, in that order, in reduction
of the Note Principal Balances thereof, until reduced to zero; (ii) if such
Realized Loss is on a Group II Loan, to the Class II-M-3, Class II-M-2 and Class
II-M-1 Notes, in that order, in reduction of the Note Principal Balances
thereof, until reduced to zero; (iii) if such Realized Loss is on a Group III
Loan, to the Class III-M-2 Notes and Class III-M-1 Notes, in that order, in
reduction of the Note Principal Balances thereof, until reduced to zero; and
(iv) if such Realized Loss is on a Group IV Loan, to the Class IV-M-3, Class
IV-M-2 and Class IV-M-1 Notes, in that order, in reduction of the Note Principal
Balances thereof, until reduced to zero. For purposes of clause THIRD all
Realized Losses will be allocated among all Loan Groups to their respective
Overcollateralization Amounts on a pro rata basis, based on the amount of
Realized Losses incurred during the related Prepayment Period which were not
covered on that Payment Date through a payment of Net Monthly Excess Cashflow,
until the aggregate Note Principal Balance of the Notes equals the aggregate
Stated Principal Balance of the Mortgage Loans (even if this results in an
Undercollateralization Amount) before being allocated to the related Notes as
provided in clause FOURTH. Realized Losses shall not be allocated to the Class A
Notes. All Realized Losses allocated to a Class of Notes will be allocated in
proportion to the Percentage Interests evidenced thereby.

                                   ARTICLE IV

               The Notes; Satisfaction and Discharge of Indenture

         Section 4.01 THE NOTES. Each Class of Notes shall be registered in the
name of a nominee designated by the Depository. Beneficial Owners will hold
interests in the Notes through the book- entry facilities of the Depository in
minimum initial Note 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 Notes) deal with the Depository as the authorized
representative of the Beneficial Owners with respect to the Notes for the
purposes of exercising the rights of Holders of the Notes hereunder. Except as
provided in the next succeeding paragraph of this Section 4.01, the rights of
Beneficial Owners with respect to the Notes 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 Notes as to which they are the Beneficial Owners. Requests and directions
from, and votes of, the Depository as Holder of the Notes 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 Noteholders and give notice to the
Depository of such record date. Without the consent of the Issuer and the
Indenture Trustee, no Note may be transferred by the Depository except to a
successor Depository that agrees to hold such Note 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 Notes it
beneficially owns in the manner prescribed in Section 4.08.

         The Notes 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 NOTES; APPOINTMENT OF NOTE REGISTRAR AND CERTIFICATE REGISTRAR. The Issuer
shall cause to be kept at the Corporate Trust Office a Note Register in which,
subject to such reasonable regulations as it may prescribe, the Note Registrar
shall provide for the registration of Notes and of transfers and exchanges of
Notes as herein provided.

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



                                       25

<PAGE>



         Subject to the foregoing, at the option of the Noteholders, Notes may
be exchanged for other Notes of like tenor and in authorized initial Note
Principal Balances evidencing the same Class and aggregate Percentage Interests
upon surrender of the Notes to be exchanged at the Corporate Trust Office of the
Note Registrar. Whenever any Notes are so surrendered for exchange, the Issuer
shall execute and the Indenture Trustee shall authenticate and deliver the Notes
which the Noteholder making the exchange is entitled to receive. Each Note
presented or surrendered for registration of transfer or exchange shall (if so
required by the Note Registrar) be duly endorsed by, or be accompanied by a
written instrument of transfer in form reasonably satisfactory to the Note
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. Notes
delivered upon any such transfer or exchange will evidence the same obligations,
and will be entitled to the same rights and privileges, as the Notes
surrendered.

         No service charge shall be made for any registration of transfer or
exchange of Notes, but the Note 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 Notes.

         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) Note Registrar under this
Indenture. The Indenture Trustee hereby accepts such appointments.

         Section 4.03 MUTILATED, DESTROYED, LOST OR STOLEN NOTES. If (i) any
mutilated Note is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Note, and (ii) there is delivered to the Indenture Trustee such security or
indemnity as may be required by it to hold the Issuer and the Indenture Trustee
harmless, then, in the absence of notice to the Issuer, the Note Registrar or
the Indenture Trustee that such Note 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 Note, a replacement Note; PROVIDED, HOWEVER, that if
any such destroyed, lost or stolen Note, but not a mutilated Note, shall have
become or within seven days shall be due and payable, instead of issuing a
replacement Note, the Issuer may pay such destroyed, lost or stolen Note when so
due or payable without surrender thereof. If, after the delivery of such
replacement Note or payment of a destroyed, lost or stolen Note pursuant to the
proviso to the preceding sentence, a bona fide purchaser of the original Note in
lieu of which such replacement Note was issued presents for payment such
original Note, the Issuer and the Indenture Trustee shall be entitled to recover
such replacement Note (or such payment) from the Person to whom it was delivered
or any Person taking such replacement Note from such Person to whom such
replacement Note 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 or the Indenture Trustee in connection therewith.



                                       26

<PAGE>



         Upon the issuance of any replacement Note under this Section 4.03, the
Issuer may require the payment by the Holder of such Note 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 Note issued pursuant to this Section 4.03 in
replacement of any mutilated, destroyed, lost or stolen Note shall constitute an
original additional contractual obligation of the Issuer, whether or not the
mutilated, destroyed, lost or stolen Note 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 Notes 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 Notes.

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

         Section 4.05 CANCELLATION. All Notes 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 Notes previously
authenticated and delivered hereunder which the Issuer may have acquired in any
manner whatsoever, and all Notes so delivered shall be promptly cancelled by the
Indenture Trustee. No Notes shall be authenticated in lieu of or in exchange for
any Notes cancelled as provided in this Section 4.05, except as expressly
permitted by this Indenture. All cancelled Notes 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 Notes have not been previously disposed of by
the Indenture Trustee.

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

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


                                       27

<PAGE>



                           (ii) the Note 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 Notes and the giving of instructions or directions
         hereunder) as the sole holder of the Notes, and shall have no
         obligation to the Beneficial Owners of the Notes;

                           (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 Notes and the
         Depository and/or the Depository Participants. Unless and until
         Definitive Notes 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 Notes to such Depository Participants; and

                           (v) whenever this Indenture requires or permits
         actions to be taken based upon instructions or directions of Holders of
         Notes evidencing a specified percentage of the Note Principal Balances
         of the Notes, the Depository shall be deemed to represent such
         percentage with respect to the Notes 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 Notes and has
         delivered such instructions to the Indenture Trustee.

         Section 4.07 NOTICES TO DEPOSITORY. Whenever a notice or other
communication to the Note Holders is required under this Indenture, unless and
until Definitive Notes 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 Notes to the
Depository, and shall have no obligation to the Beneficial Owners.

         Section 4.08 DEFINITIVE NOTES. If (i) the Depositor advises the
Indenture Trustee or the Note Registrar in writing that the Depository is no
longer willing or able to properly discharge its responsibilities as clearing
agency with respect to the Notes and the Depositor is unable to locate a
qualified successor within 30 days, (ii) the Depositor, at its option (with the
consent of the Indenture Trustee, which consent shall not by unreasonably
withheld), elects to terminate the book-entry system through the Depository or
(iii) after the occurrence of an Event of Default, Beneficial Owners of Notes
representing beneficial interests aggregating at least a majority of the Note
Principal Balances of the Notes 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 Note Registrar shall request
that the Depository notify all Beneficial Owners and the Indenture Trustee of
the occurrence of any such event and of the availability of Definitive Notes to
Beneficial Owners requesting the same. Upon surrender to the Indenture Trustee
of the global Note or definitive typewritten Notes representing the Book-Entry
Notes by the Depository, accompanied by registration instructions, the Note
Registrar will re-issue the Book-entry Notes as Definitive Notes issued in the
respective Note Principal Balances owned by individual Note Owners. None of the
Issuer, the Note Registrar or the Indenture Trustee shall be liable for any
delay in delivery of such instructions and may conclusively rely on, and shall
be


                                       28

<PAGE>



protected in relying on, such instructions. Upon the issuance of Definitive
Notes, the Indenture Trustee shall recognize the Holders of the Definitive Notes
as Noteholders.

         Section 4.09 TAX TREATMENT. The Issuer has entered into this Indenture,
and the Notes will be issued with the intention that, for federal, state and
local income, single business and franchise tax purposes, the Notes will qualify
as indebtedness. The Issuer and the Indenture Trustee (in accordance with
Section 6.06 hereof), by entering into this Indenture, and each Noteholder, by
its acceptance of its Note (and each Beneficial Owner by its acceptance of an
interest in the applicable Book-Entry Note), agree to treat the Notes 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 Notes except as to (i)
rights of registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Notes, (iii) rights of Noteholders 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), and (vi)
the rights of Noteholders 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 Notes and shall release and deliver the Collateral to or
upon the order of the Issuer, when

                  (A) either

                  (1) all Notes theretofore authenticated and delivered (other
         than (i) Notes that have been destroyed, lost or stolen and that have
         been replaced or paid as provided in Section 4.03 hereof and (ii) Notes
         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 Notes 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,

and the Issuer, in the case of a. or b. above, has irrevocably deposited or

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

                              Default and Remedies

         Section 5.01 EVENTS OF DEFAULT. The Issuer shall deliver to the
Indenture Trustee, within five days after learning of the occurrence of a
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 Notes, 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 at the written direction of the Holders of Notes representing
not less than a majority of the aggregate Note Principal Balance of the Notes
may declare the Notes to be immediately due and payable, by a notice in writing
to the Issuer (and to the Indenture Trustee if such notice is given by
Noteholders), and upon any such declaration the unpaid Note Principal Balance of
the Notes, together with accrued and unpaid interest thereon through the date of
acceleration, shall become immediately due and payable.

         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 that, Holders of the Notes representing
not less than a majority of the aggregate Note Principal Balance of the Notes 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 has paid or deposited with the
         Indenture Trustee a sum sufficient to pay:

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

                           (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

                           (ii) all Events of Default, other than the nonpayment
         of the principal of the Notes that has become due solely by such
         acceleration, have been cured or waived as provided in Section 5.12.

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.


                                       32

<PAGE>



         (a) The Issuer covenants that if (i) default is made in the payment of
any interest on any Note 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 Note when the same
becomes due and payable, the Issuer shall, upon demand of the Indenture Trustee,
at the direction of the Holders of a majority of the aggregate Note Principal
Balances of the Notes, pay to the Indenture Trustee, for the benefit of the
Holders of Notes, the whole amount then due and payable on the Notes for
principal and interest, with interest at the applicable Note 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, 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 Notes and collect in the manner provided by
law out of the property of the Issuer or other obligor the Notes, wherever
situated, the monies adjudged or decreed to be payable.

         (c) If an Event of Default occurs and is continuing, the Indenture
Trustee, 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 Noteholders by such
appropriate Proceedings as directed in writing by Holders of a majority of the
aggregate Note Principal Balances of the Notes, 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 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 Notes 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 Notes, or to the creditors or property of the Issuer
or such other obligor, the Indenture Trustee, as directed in writing by Holders
of a majority of the aggregate Note Principal Balances of the Notes,
irrespective of whether the principal of any Notes 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
         Notes 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


                                       33

         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) and of the
         Noteholders allowed in such Proceedings;

                           (ii) unless prohibited by applicable law and
         regulations, to vote on behalf of the Holders of Notes 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 Noteholders 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 or the Holders of Notes 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 Noteholders to make
payments to the Indenture Trustee, and, in the event that the Indenture Trustee
shall consent to the making of payments directly to such Noteholders, 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.

         (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 Noteholder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder thereof or to
authorize the Indenture Trustee to vote in respect of the claim of any
Noteholder 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 Notes, may be enforced by the Indenture Trustee without the
possession of any of the Notes 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 Notes, subject to Section 5.05 hereof.

         (g) In any Proceedings brought by the Indenture Trustee (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 Notes, and it shall not be necessary to
make any Noteholder 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 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 Notes 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 Notes 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
         Notes; and

                           (iv) sell the Trust Estate or any portion thereof or
         rights or interest therein, at one or more public or private sales
         called and conducted in any manner permitted by law;

PROVIDED, HOWEVER, that the Indenture Trustee may not sell or otherwise
liquidate the Trust Estate following an Event of Default, unless (A) the
Indenture Trustee obtains the consent of the Holders of 100% of the aggregate
Note Principal Balance of the Notes, (B) the proceeds of such sale or
liquidation distributable to the Holders of the Notes are sufficient to
discharge in full all amounts then due and unpaid upon such Notes for principal
and interest 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 Notes as they would have become due if the Notes
had not been declared due and payable, and the Indenture Trustee obtains the
consent of the Holders of a majority of the aggregate Note Principal Balance of
the Notes. 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 I Loans, Group II Loans, Group III Loans or Group IV Loans
pursuant to this Article V, it shall pay out the money or property in the
following order:

                  FIRST: to the Indenture Trustee and Master Servicer for
         amounts due under Section 6.07 hereof;

         Notes (other than Basis Risk Shortfall Carry-Forward Amounts and Net
         WAC Shortfall Carry-Forward Amounts) with respect to interest, first,

         concurrently, and second, to the Class I-M-1, Class II-M-1, Class
         III-M-1 and Class IV-M-1 Noteholders, concurrently, third, to the Class
         I-M-2, Class II-M-2, Class III-M-2 and Class IV-M-2 Noteholders,
         concurrently, and fourth, to the Class I-M-3, Class II-M-3 and Class
         IV-M-3 Noteholders, concurrently, according to the amounts due and
         payable on the Notes for interest;

                  THIRD: to Noteholders for amounts due and unpaid on the
         Noteholders with respect to principal, and to each Noteholder ratably,
         without preference or priority of any kind, according to the amounts
         due and payable on such Notes for principal, until the Note Principal
         Balance of each such Class is reduced to zero;

                  FOURTH: to the related Class M Notes, in order of payment
         priority, the amount of any related Allocated Realized Loss Amount not
         previously paid;

                  FIFTH: to the Noteholders for Basis Risk Shortfall
         Carry-Forward Amounts and Net WAC Shortfall Carry-Forward Amounts, with
         respect to amounts remaining with respect to the Group I Loans,
         sequentially, to the Class I-A, Class I-M-1, Class I-M-2 and Class
         I-M-3 Noteholders, with respect to amounts remaining with respect to
         the Group II Loans, sequentially, to the Class II-A, Class II-M-1,
         Class II-M-2 and Class II-M-3 Noteholders, with respect to amounts
         remaining with respect to the Group III Loans, sequentially, to the
         Class III-A, Class III-M-1 and Class III-M-2 Noteholders, and with
         respect to amounts remaining with respect to the Group IV Loans,
         sequentially, to the Class IV-A, Class IV-M- 1, Class IV-M-2 and Class
         IV-M-3 Noteholders; and

                  SIXTH: to the payment of the remainder, if any, to the holders
         of the Trust Certificates on behalf of the Issuer.

         The Indenture Trustee may fix a record date and Payment Date for any
payment to Noteholders pursuant to this Section 5.04. At least 15 days before
such record date, the Indenture Trustee shall mail to each Noteholder a notice
that states the record date, the Payment Date and the amount to be paid.

         Section 5.05 OPTIONAL PRESERVATION OF THE TRUST ESTATE. If the Notes
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 elect to take and maintain possession of the
Trust Estate. It is the desire of the parties hereto and the Noteholders that
there be at all times sufficient funds for the payment of principal of and
interest on the Notes and other obligations of the Issuer and the Indenture
Trustee, 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.

         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; and

                           (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 Note Principal Balances of
         the Notes.

It is understood and intended that no one or more Holders of Notes 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 Notes 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

Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or

adversely to the Indenture Trustee or to such Noteholder, then and in every such
case the Issuer, the Indenture Trustee and the Noteholders 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 and the Noteholders shall continue as though no such
Proceeding had been instituted.

conferred upon or reserved to the Indenture Trustee or to the Noteholders 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 or any Holder of any Note 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 or to the Noteholders may be exercised from time to time, and as often
as may be deemed expedient, by the Indenture Trustee or by the Noteholders, as
the case may be.

         Section 5.11 CONTROL BY NOTEHOLDERS. The Holders of a majority of the
aggregate Note Principal Balances of Notes shall have the right to direct the
time, method and place of conducting any Proceeding for any remedy available to
the Indenture Trustee with respect to the Notes 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) any direction to the Indenture Trustee to sell
         or liquidate the Trust Estate shall be by Holders of Notes representing
         not less than 100% of the Note Principal Balances of the Notes; and

                           (iii) 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 Notes representing a majority of the
         Note Principal Balances of the Notes.

Notwithstanding the rights of Noteholders set forth in this Section 5.11 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 Notes as provided in Section 5.02 hereof,
the Holders of Notes representing not less than a majority of the aggregate Note
Principal Balance of the Notes 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 Notes, or (b) in respect of a covenant or provision
hereof which cannot be modified or amended without the consent of the Holder of
each Note. In the case of any such waiver, the Issuer, the Indenture Trustee and
the Holders of the Notes shall be restored to their


                                       38

<PAGE>



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 Note 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 Noteholder, or group of
Noteholders, in each case holding in the aggregate more than 10% of the Note
Principal Balances of the Notes or (c) any suit instituted by any Noteholder for
the enforcement of the payment of principal of or interest on any Note on or
after the respective due dates expressed in such Note 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.

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

Indenture shall have been paid. The Indenture Trustee, may from time to time
postpone any public Sale by public announcement made at the time and place of

         returned to the Holders thereof after being appropriately stamped to
         show such partial payment;

                              The Indenture Trustee

         Section 6.01 DUTIES OF INDENTURE TRUSTEE. (a) If an Event of Default

         requirements of this Indenture; however, the Indenture Trustee shall
         examine the certificates, reports, documents, Issuer Requests or other
         instruments 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:

                           (iii) the Indenture Trustee shall not be liable with

such risk or liability is not reasonably assured to it.

         (f) For the limited purpose of effecting any action to be undertaken by

<PAGE>



responsible for any willful misconduct or negligence on the part of any agent,
attorney, custodian or nominee so appointed.

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

         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 Notes 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 Note 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, the Notes or any other Basic Document, it shall not
be accountable for the Issuer's use of the proceeds from the Notes, 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 Notes or in the Notes 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 Noteholder 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 Note, 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 Noteholders.

         Section 6.06 REPORTS BY INDENTURE TRUSTEE TO HOLDERS AND TAX
ADMINISTRATION. The Indenture Trustee shall deliver to each Noteholder 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.
On each Payment Date the Indenture


                                       44

<PAGE>



Trustee shall be entitled to withdraw from the Payment Account, the Indenture
Trustee Fee for such Payment Date in accordance with Section 3.07 of the
Servicing Agreement. 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 and under the other Basic
Documents. The Indenture Trustee shall notify the Issuer promptly of any 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. Holders of a majority of Note
Principal Balances of the Notes may remove the Indenture Trustee by so notifying
the Indenture Trustee and may appoint a successor Indenture Trustee. The Issuer
shall, 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, promptly appoint a successor Indenture Trustee.

         A successor Indenture Trustee shall deliver a written acceptance of its
appointment to the retiring Indenture Trustee and to the Issuer. Thereupon, the
resignation or removal of the retiring


                                       45

<PAGE>



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 Noteholders. The retiring Indenture Trustee shall promptly transfer all
property held by it as Indenture Trustee to the successor Indenture Trustee.

         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 or the Holders of a majority of Note Principal
Balances of the Notes 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 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 Notes 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 Notes so
authenticated; and if at that time any of the Notes shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Notes 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 Notes 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
Noteholders, 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 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.

         (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:

                           (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.

same, in a manner and under circumstances that are not inconsistent with the
provisions of this Indenture, including for the purposes of any repurchase by
the Master Servicer of a Mortgage Loan pursuant to Section 3.18 of the Servicing

Certificateholder shall have the option to redeem the Notes, in whole, but not
in part, on any Payment Date on or after 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 10% of the aggregate Stated Principal Balance of
the Mortgage Loans as of Cut-off Date. The aggregate redemption price (the
"Redemption Price") for the Notes, will be equal to the unpaid Note Principal
Balance of the Notes as of the Payment Date on which the proposed redemption
will take place in accordance with the foregoing, together with accrued and
unpaid interest thereon at the applicable Note Interest Rate through such
Payment Date

Carry-Forward Amount and Net WAC Shortfall Carry-Forward Amount), plus an amount
sufficient to pay in full all amounts owing to the Indenture Trustee under this

written notice of its exercise of such option to the Indenture Trustee, the
Owner Trustee and the Master Servicer at least 15 days prior to its exercise.
Following receipt of the notice, the Indenture Trustee shall provide notice to
the Noteholders of the final payment on the Notes. In addition, the Majority
Certificateholder shall, not less than one Business Day prior to the proposed
Payment Date on which such redemption is to be made, deposit the Redemption
Price specified in (a) above with the Indenture Trustee, who shall deposit the
Redemption Price into the Payment Account and shall, on the Payment Date after
receipt of the funds, apply such funds to make final payments of principal and
interest on the Notes in accordance with Section 3.05(b) and (c) hereof and
payment in full to the Indenture Trustee, and this Indenture shall be discharged
subject to the provisions of Section 4.10 hereof. If for any reason the amount
deposited by the Majority Certificateholder is not sufficient to make such
redemption or such redemption cannot be completed for any reason, (a) the amount
so deposited by the Majority Certificateholder with the Indenture Trustee shall
be immediately returned to the Majority Certificateholder in full and shall not
be used for any other purpose or be deemed to be part of the Trust Estate and
(b) the Note Principal Balance of the Notes shall continue to bear interest at
the related Note Interest Rate.

any such supplemental indenture and to make any further appropriate agreements
and stipulations that may be therein contained.

supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture or of
modifying in any manner the rights of the Holders of the Notes under this

indenture or indentures supplemental hereto for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or of modifying in any manner the rights of the Holders of
the Notes under this Indenture; PROVIDED, HOWEVER, that no such supplemental
indenture shall, without the consent of the Holder of each Note affected
thereby:

                           (i) change the date of payment of any installment of
         principal of or interest on any Note, or reduce the principal amount
         thereof or the interest rate thereon, change the provisions of this
         Indenture relating to the application of collections on, or the

         coin or currency in which, any Note or the interest thereon is payable,
         or impair the right to institute suit for the enforcement of the
         provisions of this Indenture requiring the application of funds

         Balances of the Notes, the consent of the Holders of which is required
         for any such supplemental indenture, or the consent of the Holders of

         of this Indenture or certain defaults hereunder and their consequences
         provided for in this Indenture;

                           (iii) modify or alter the provisions of the proviso
         to the definition of the term "Outstanding" or modify or alter the
         exception in the definition of the term "Holder";

                           (iv) reduce the percentage of the Note Principal

                           (v) modify any provision of this Section 9.02 except
         to increase any percentage specified herein or to provide that certain
         additional provisions of this Indenture or the Basic Documents cannot
         be modified or waived without the consent of the Holder of each Note
         affected thereby;

                           (vi) modify any of the provisions of this Indenture
         in such manner as to affect the calculation of the amount of any
         payment of interest or principal due on any Note on any Payment Date

         calculation); or

                           (vii) permit the creation of any lien ranking prior
         to or on a parity with the lien of this Indenture with respect to any
         part of the 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 Note
         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 American
Home Mortgage Securities LLC) 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.

         It shall not be necessary for any Act of Noteholders 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 Notes to which such amendment or supplemental
indenture relates a notice setting forth in general terms 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 Notes 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 Notes
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 NOTES TO SUPPLEMENTAL INDENTURES. Notes
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 Notes 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 Notes.

         (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 such securities made the


                                       63

<PAGE>



         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 Note Principal Balances of the Notes, 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 Note Principal Balances of the Notes.

                           (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 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 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
         Note Principal Balances of the Notes, 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 Note Principal
         Balances of the Notes.

         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 NOTEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Noteholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Noteholders 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 Noteholders 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 Notes shall be proved by the Note Registrar.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other action by the Holder of any Notes shall bind the Holder of every
Note 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 Note.

         Section 10.04 NOTICES ETC., TO INDENTURE TRUSTEE ISSUER AND RATING
AGENCIES. Any request, demand, authorization, direction, notice, consent, waiver
or Act of Noteholders 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 Noteholders is to be made upon, given or
furnished to or filed with:

                           (i) the Indenture Trustee by any Noteholder or by the
         Issuer shall be sufficient for every purpose hereunder if made, given,
         furnished or filed in writing to or with the Indenture Trustee at the
         Corporate Trust Office. The Indenture Trustee shall promptly transmit
         any notice received by it from the Noteholders to the Issuer; or

                           (ii) the Issuer by the Indenture Trustee or by any
         Noteholder shall be sufficient for every purpose hereunder if in
         writing and mailed first-class, postage prepaid

         to the Issuer addressed to: American Home Mortgage Investment Trust
         2004-1, 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 Noteholders
         to the Indenture Trustee; or

         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 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 NOTEHOLDERS; WAIVER. Where this Indenture
provides for notice to Noteholders 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 Noteholder affected by such
event, at such Person's address as it appears on the Note 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 Noteholders is given by mail,
neither the failure to mail such notice nor any defect in any notice so mailed
to any particular Noteholder shall affect the sufficiency of such notice with
respect to other Noteholders, 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 Noteholders 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 Noteholders when such notice is required to be
given pursuant to any provision of this Indenture, then any manner of 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 Notes 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 Notes 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     [RESERVED].

         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 Notes 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.

         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 Noteholders 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 Notes 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


                                       67

<PAGE>



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 Noteholder, by accepting a Note, 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 Notes, 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, 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 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) and except to the extent that the Indenture Trustee may reasonably
determine that such disclosure is consistent with its obligations hereunder.

         American Home Mortgage Investment Trust 2004-1 (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

Note Principal Balance of this Note (this "Note") outstanding from time to time
as provided below.

         This Note is one of a duly authorized issue of the Issuer's
Mortgage-Backed Notes, Series 2004-1 (the "Notes"), issued under an Indenture
dated as of March 31, 2004 (the "Indenture"), between the Issuer and Wells Fargo

statement of the respective rights thereunder of the Issuer, the Indenture
Trustee, and the Holders of the Notes and the terms upon which the Notes are to

Majority Certificateholder on any Payment Date on or after 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 10% of the aggregate Stated
Principal Balance of the Mortgage Loans as of Cut-off Date.

         The Issuer shall not be liable upon the indebtedness evidenced by the
Notes except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Notes. The assets included in the
Trust Estate will be the sole source of payments on the Class [_] Notes, and
each Holder hereof, by its acceptance of this Note, agrees that (i) such Note
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, AHM SPV III, LLC, American
Home Mortgage Securities LLC, American Home Mortgage Investment Corp., 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 [__] Notes pursuant to the Indenture and the rights conveyed to the Issuer
under the Indenture.

         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note 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 Note Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Note, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Note 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 Note (or
one or more predecessor Notes) effected by payments of principal made on any
Payment Date shall be binding upon all Holders of this Note and of any Note
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, whether or not such payment is noted on such Note. The final
payment of this Note 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 Note delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Note shall carry the right to unpaid principal and interest that were
carried by such other Note.

         If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Notes, the Notes 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
Note Principal Balance of the Notes, the amount payable to the Holder of this
Note will be equal to the sum of the unpaid Note Principal Balance of the Notes,
together with accrued and unpaid interest thereon as described in the Indenture.
The Indenture provides that, notwithstanding


                                      A-1-3

<PAGE>



the acceleration of the maturity of the Notes, under certain circumstances
specified therein, all amounts collected as proceeds of the Trust Estate
securing the Notes or otherwise shall continue to be applied to payments of
principal of and interest on the Notes 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 Note or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Note with Plan
Assets or (2) (A) the acquisition, holding and transfer of a Note will not give
rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code and (B) the Notes are rated investment grade or better and such
person believes that the Notes are properly treated as indebtedness without
substantial equity features for purposes of the DOL Regulations, and agrees to
so treat the Notes. Alternatively, regardless of the rating of the Notes, 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 Note 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 Note may be registered on the Note Register of
the Issuer. Upon surrender for registration of transfer of, or presentation of a
written instrument of transfer for, this Note 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 Notes
of any authorized denominations and of a like aggregate initial Note Principal
Balance, will be issued to the designated transferee or transferees.

         Prior to the due presentment for registration of transfer of this Note,
the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture
Trustee may treat the Person in whose name this Note is registered as the owner
of such Note (i) on the applicable Record Date for the purpose of making
payments and interest of such Note, and (ii) on any other date for all other
purposes whatsoever, as the owner hereof, whether or not this Note 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 Notes under the Indenture at any
time by the Issuer with the consent of the Holders of a majority of each Class
of Notes affected thereby. The Indenture also contains provisions permitting the
Holders of Notes representing specified percentages of the aggregate Note
Principal Balance of the Notes on behalf of the Holders of all the Notes, to
waive any past Default under the Indenture and its


                                      A-1-4

<PAGE>



consequences. Any such waiver by the Holder, at the time of the giving thereof,
of this Note (or any one or more predecessor Notes) shall bind the Holder of
every Note 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 Note. 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 Notes issued thereunder.

         Initially, the Notes will be registered in the name of CEDE & Co. as
nominee of DTC, acting in its capacity as the Depository for the Notes. The
Notes will be delivered by the clearing agency in denominations as provided in
the Indenture and subject to certain limitations therein set forth. The Notes
are exchangeable for a like aggregate initial Note Principal Balance of Notes 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 Note shall not be entitled to
any benefit under the Indenture, or be valid or obligatory for any purpose.

         AS PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS
NOTE 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.

         American Home Mortgage Investment Trust 2004-1 (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 succeeding Business Day (each a
"Payment Date"), commencing in April 2004 and ending on or before the Payment
Date occurring in [______] (the "Final Scheduled Payment Date") and to pay
interest on the Note Principal Balance of this Note (this "Note") outstanding
from time to time as provided below.

         This Note is one of a duly authorized issue of the Issuer's
Mortgage-Backed Notes, Series 2004-1 (the "Notes"), issued under an Indenture
dated as of March 31, 2004 (the "Indenture"), between the Issuer and Wells Fargo
Bank, National Association, 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 Notes and the terms upon which the Notes are to
be authenticated and delivered. All terms used in this Note which are defined in
the Indenture shall have the meanings assigned to them in the Indenture.

         Payments of principal and interest on this Note will be made on each
Payment Date to the Noteholder of record as of the related Record Date. The
"Note Principal Balance" of a Note as of any date of determination is equal to
the initial Note Principal Balance thereof, reduced by the aggregate of all
amounts previously paid with respect to such Note on account of principal and
the aggregate amount of cumulative Realized Losses allocated to such Note on all
prior Payment Dates.

         The principal of, and interest on, this Note 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 Note shall
be equal to this Note's pro rata share of the aggregate payments on all Class
[__]-M-[_] Notes as described above, and shall be applied as between interest
and principal as provided in the Indenture.

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


                                      A-2-2

<PAGE>



         The Notes are subject to redemption in whole, but not in part, by the
Majority Certificateholder on any Payment Date on or after the Payment Date on
which the aggregate Stated Principal Balance of the Mortgage Loans is less than
or equal to 10% of aggregate Stated Principal Balance of the Mortgage Loans as
of Cut-off Date.

         The Issuer shall not be liable upon the indebtedness evidenced by the
Notes except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Notes. The assets included in the
Trust Estate will be the sole source of payments on the Class [__]- M-[_] Notes,
and each Holder hereof, by its acceptance of this Note, agrees that (i) such
Note 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, American Home Mortgage
Securities LLC, American Home Mortgage Investment Corp., 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 [__]-M-[_]
Notes pursuant to the Indenture and the rights conveyed to the Issuer under the
Indenture.

         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note 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 Note Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Note, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Note 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 Note (or
one or more predecessor Notes) effected by payments of principal made on any
Payment Date shall be binding upon all Holders of this Note and of any Note
issued upon the registration of transfer thereof or in exchange therefor or in
lieu thereof, whether or not such payment is noted on such Note. The final
payment of this Note 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 Note delivered under the
Indenture, upon registration of transfer of or in exchange for or in lieu of any
other Note shall carry the right to unpaid principal and interest that were
carried by such other Note.

         If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Notes, the Notes 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
Note Principal Balance of the Notes, the amount payable to the Holder of this
Note will be equal to the sum of the unpaid Note Principal Balance of the Notes,
together with accrued and unpaid interest thereon as described in the Indenture.
The Indenture provides that, notwithstanding the acceleration of the maturity of
the Notes, under certain circumstances specified therein, all amounts collected
as proceeds of the Trust Estate securing the Notes or otherwise shall continue
to


                                      A-2-3

<PAGE>



be applied to payments of principal of and interest on the Notes 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 Note or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Note with Plan
Assets or (2) (A) the acquisition, holding and transfer of a Note will not give
rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code and (B) the Notes are rated investment grade or better and such
person believes that the Notes are properly treated as indebtedness without
substantial equity features for purposes of the DOL Regulations, and agrees to
so treat the Notes. Alternatively, regardless of the rating of the Notes, 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 Note 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 Note may be registered on the Note Register of
the Issuer. Upon surrender for registration of transfer of, or presentation of a
written instrument of transfer for, this Note 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 Notes
of any authorized denominations and of a like aggregate initial Note Principal
Balance, will be issued to the designated transferee or transferees.

         Prior to the due presentment for registration of transfer of this Note,
the Issuer, the Indenture Trustee and any agent of the Issuer or the Indenture
Trustee may treat the Person in whose name this Note is registered as the owner
of such Note (i) on the applicable Record Date for the purpose of making
payments and interest of such Note, and (ii) on any other date for all other
purposes whatsoever, as the owner hereof, whether or not this Note 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 Notes under the Indenture at any
time by the Issuer with the consent of the Holders of a majority of each Class
of Notes affected thereby. The Indenture also contains provisions permitting the
Holders of Notes representing specified percentages of the aggregate Note
Principal Balance of the Notes on behalf of the Holders of all the Notes, 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 Note (or any one or
more predecessor Notes) shall bind the Holder of every Note issued upon the
registration of


                                      A-2-4

<PAGE>



transfer hereof or in exchange hereof or in lieu hereof, whether or not notation
of such consent or waiver is made upon such Note. 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 Notes
issued thereunder.

         Initially, the Notes will be registered in the name of Cede & Co. as
nominee of DTC, acting in its capacity as the Depository for the Notes. The
Notes will be delivered by the clearing agency in denominations as provided in
the Indenture and subject to certain limitations therein set forth. The Notes
are exchangeable for a like aggregate initial Note Principal Balance of Notes 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 Note shall not be entitled to
any benefit under the Indenture, or be valid or obligatory for any purpose.

         AS PROVIDED IN THE INDENTURE, THIS NOTE AND THE INDENTURE CREATING THIS
NOTE 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.

(in the absence of manifest error) be final and binding.

         ONE-YEAR LIBOR: With respect to any Accrual Period, the rate determined

         than two Reference Banks provide such offered quotations, One-Year
         LIBOR for the related Accrual Period shall be the higher of (i)
         One-Year LIBOR as determined on the previous Interest Determination
         Date and (ii) the Reserve Interest Rate.

                           (iii) If no such quotations can be obtained and no
         Reference Bank rate is available, One-Month LIBOR will be the One-Month
