                  INDENTURE, dated as of June 1, 2004 (the "Indenture"), between
SEQUOIA HELOC TRUST 2004-1, a Delaware statutory trust (the "Issuer"), and WELLS
FARGO BANK, N.A., a national banking association, as trustee (the "Indenture
Trustee").

                  Each party agrees as follows for the benefit of the other
party and for the equal and ratable benefit of the Holders of the Issuer's HELOC
Asset-Backed Notes, Series 2004-1 (the "Notes").

                  As security for the payment and performance by the Issuer of
its obligations under this Indenture and the Notes, the Issuer has agreed to
assign the Collateral (as defined below) to the Indenture Trustee on behalf of
the Noteholders and the Insurer.

                  Ambac Assurance Corporation (the "Insurer") has issued and
delivered a certificate guaranty insurance policy for the Notes, dated the
Closing Date (the "Policy"), pursuant to which the Insurer guarantees the
Insured Amounts and Preference Amount (as defined in the Policy).

                  As an inducement to the Insurer to issue and deliver the
Policy, the Issuer and the Insurer have executed and delivered the Insurance and
Indemnity Agreement, dated as of June 29, 2004 (as amended from time to time,
the "Insurance Agreement"), among the Insurer, the Issuer, the Servicer, the
Seller, the Depositor and the Indenture Trustee.

                  As an additional inducement to the Insurer to issue the
Policy, and as security for the performance by the Issuer of the Insurer Issuer
Secured Obligations and as security for the performance by the Issuer of the
Indenture Trustee Issuer Secured Obligations, the Issuer has agreed to grant and
assign the Collateral (as defined below) to the Indenture Trustee for the
benefit of the Issuer Secured Parties, as their respective interests may appear.

<PAGE>

                                 GRANTING CLAUSE

The Issuer hereby Grants to the Indenture Trustee at the Closing Date, for the
benefit of the Issuer Secured Parties all of the Issuer's right, title and
interest in and to: (i) a pool (the "Pool") of certain adjustable rate home
equity revolving credit line loans (the "Mortgage Loans") (including any
Additional Balances related thereto) in each case as set forth in Exhibit A to
the Sale and Servicing Agreement; (ii) the collections in respect of the
Mortgage Loans conveyed to the Trust and received (or, in the case of Interest
Collections, due) (A) in the case of Interest Collections, with respect to the
Principal Balance thereof as of such date, after the close of business on the
Cut-Off Date and (B) in the case of all Principal Collections and Interest
Collections on Additional Balances created after the Cut-Off Date, after the
close of business on the Issue Date; (iii) property that secured a Mortgage Loan
that has been acquired by foreclosure or deed in lieu of foreclosure; (iv)
rights of the Depositor under hazard insurance policies covering the Mortgaged
Properties; (v) amounts on deposit from time to time in the Collection Account
and the Distribution Account; (vi) all rights under the Mortgage Loan Purchase
and Sale Agreement and the Purchase and Servicing Agreements assigned to the
Issuer (including all representations and warranties of the Seller contained
therein) and all rights of the Issuer under the Sale and Servicing Agreement;
(vii) the Policy (solely for the benefit of the Noteholders); and (viii) any and
all proceeds of the foregoing (the items set forth in (i) through (viii) above,
the "Collateral").

                  The foregoing Grant is made in trust to the Indenture Trustee,
for the benefit first, of the Indenture Trustee and the Holders of the Notes,
and second, for the benefit of the Insurer. The Indenture Trustee hereby
acknowledges such Grant, accepts the trusts under this Indenture in accordance
with the provisions of this Indenture and agrees to perform its duties required
in this Indenture to the best of its ability to the end that the interests of
such parties, recognizing the priorities of their respective interests may be
adequately and effectively protected.

                  The Indenture Trustee hereby agrees that it will hold the
Policy in trust and that it will hold any proceeds of any claim made upon the
Policy solely for the use and the benefit of the Noteholders in accordance with
the terms hereof and the terms of the Policy.

                  Neither the Indenture Trustee nor the Issuer assumes or shall
assume any obligation under any Credit Line Agreement that provides for the
funding of future Draws to the Mortgagor thereunder, and neither the Indenture
Trustee nor the Issuer shall be obligated or permitted to fund any such future
Draws.

                  All obligations of the Issuer hereunder shall be effective as
of the Closing Date.

                                    ARTICLE I

                   Definitions and Incorporation by Reference

                  SECTION 1.1. Definitions. Except as otherwise specified
herein, the following terms have the respective meanings set forth in Annex A to
this Indenture.

                  SECTION 1.2. Incorporation by Reference of the Trust Indenture
Act. Whenever this Indenture refers to a provision of the Trust Indenture Act
("TIA"), the provision is

                                       2

<PAGE>

incorporated by reference in and made a part of this Indenture. The following
TIA terms used in this Indenture have the following meanings:

                  "Commission" means the Securities and Exchange Commission.

                  "indenture securities" means the Notes.

                  "indenture security holder" means a Holder of a Note.

                  "indenture to be qualified" means this Indenture.

                  "Indenture Trustee" or "institutional trustee" means the
Indenture Trustee.

                  "obligor" on the indenture securities means the Issuer.

                  All other TIA terms used in this Indenture that are defined by
the TIA, or defined by Commission rule have the meaning assigned to them by such
definitions.

                  SECTION 1.3. Rules of Construction. Unless the context
otherwise requires:

                        (i) a term has the meaning assigned to it;

                        (ii) an accounting term not otherwise defined has the
            meaning assigned to it in accordance with generally accepted
            accounting principles as in effect from time to time;

                        (iii) "or" is not exclusive;

                        (iv) "including" means including without limitation; and

            in the plural include the singular.

                  SECTION 1.4. Action by or Consent of Noteholders and Residual
Certificateholders. Whenever any provision of this Indenture refers to action to
be taken, or consented to, by Noteholders or Residual Certificateholders, such
provision shall be deemed to refer to the Noteholder or Residual
Certificateholder, as the case may be, of record as of the Record Date
immediately preceding the date on which such action is to be taken, or consent
given, by Noteholders or Residual Certificateholders. Solely for the purposes of
any action to be taken, or consented to, by Noteholders, any Note registered in
the name of Sequoia Mortgage Funding Corporation or any Affiliate thereof shall
be deemed not to be outstanding; provided, however, that, solely for the purpose
of determining whether the Indenture Trustee is entitled to rely upon any such
action or consent, only Notes which the Indenture Trustee actually knows to be
so owned shall be so disregarded.

                  SECTION 1.5. Conflict with TIA. If any provision hereof
limits, qualifies or conflicts with a provision of the TIA that is required
under the TIA to be part of and govern this Indenture, the latter provision
shall control and all provisions required by the TIA are hereby

                                       3

<PAGE>

incorporated by reference. If any provision of this Indenture modifies or
excludes any provision of the TIA that may be so modified or excluded, the
latter provisions shall be deemed to apply to this Indenture as so modified or
to be excluded, as the case may be.

                                   ARTICLE II

substitutions and other variations as are required or permitted by this
Indenture and may have such letters, numbers or other marks of identification

execution of the Notes. Any portion of the text of any Notes may be set forth on
the reverse thereof, with an appropriate reference thereto on the face of the
Note.

                  Each Note shall be dated the date of its authentication. The
terms of the Notes set forth in Exhibit A are part of the terms of this
Indenture.

                  SECTION 2.2. 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 original or
facsimile.

                  Notes bearing the original 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 authenticate and deliver Notes for
original issue in the principal amount of $317,044,000. The Notes outstanding at
any time may not exceed such amount.

                  Each Note shall be dated the date of its authentication. The
Notes shall be issuable as registered Notes in the minimum denomination 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 attached to 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 attached to any Notes shall be
conclusive evidence, and the only evidence, that such Notes have been duly
authenticated and delivered hereunder. Subject to Section 2.11, the Notes shall
be Book Entry Notes.

                                       4

                  SECTION 2.3. Registration; Registration of Transfer and
Exchange. The Issuer shall cause to be kept a register (the "Note Register") in
which, subject to such reasonable regulations as it may prescribe, the Issuer
shall provide for the registration of Notes and the registration of transfers of
Notes. The Indenture Trustee shall be "Note Registrar" for the purpose of
registering Notes and transfers of Notes as herein provided. Upon any
resignation of any Note Registrar, the Issuer shall promptly appoint a successor
or, if it elects not to make such an appointment, assume the duties of Note
Registrar.

                  If a Person other than the Indenture Trustee is appointed by
the Issuer as Note Registrar, the Issuer will give the Indenture Trustee and the
Insurer prompt written notice of the appointment of such Note Registrar and of
the location, and any change in the location, of the Note Register, and the
Indenture Trustee and the Insurer shall have the right to inspect the Note
Register at all reasonable times and to obtain copies thereof. The Indenture
Trustee shall have the right to rely upon a certificate executed on behalf of
the Note Registrar by an Authorized Officer thereof as to the names and
addresses of the Holders of the Notes and the principal amounts and number of
such Notes.

                  Upon surrender for registration or transfer of any Note at the
office or agency of the Issuer to be maintained as provided in Section 3.2, and
if the requirements of Section 8-401(1) of the UCC are met, the Issuer shall
execute and cause the Indenture Trustee to authenticate one or more new Notes,
in any authorized denominations, of like aggregate principal amount. A
Noteholder may also obtain from the Indenture Trustee, in the name of the
designated transferee or transferees one or more new Notes, in any authorized
denominations, of like aggregate principal amount. Such requirements shall not
be deemed to create a duty in the Indenture Trustee to monitor the compliance by
the Issuer with Section 8-401 of the UCC.

                  At the option of the Holder, Notes may be exchanged for other
Notes in any authorized denominations, of like aggregate principal amount, upon
surrender of the Notes to be exchanged at such office or agency. Whenever any
Notes are so surrendered for exchange, and if the requirements of Section
8-401(1) of the UCC are met, the Issuer shall execute and upon its request the
Indenture Trustee shall authenticate the Notes which the Noteholder making the
exchange is entitled to receive. Such requirements shall not be deemed to create
a duty in the Indenture Trustee to monitor the compliance by the Issuer with
Section 8-401 of the UCC.

                  All Notes issued upon any registration of transfer or exchange
of Notes shall be the valid obligations of the Issuer, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Notes surrendered
upon such registration of transfer or exchange.

                  Every Note presented or surrendered for registration of
transfer or exchange shall be (i) duly endorsed by, or be accompanied by a
written instrument of transfer in the form attached to Exhibit A, duly executed
by the Holder thereof or such Holder's attorney duly authorized in writing, with
such signature guaranteed by an "eligible guarantor institution" meeting the
requirements of the Note Registrar all in accordance with the Exchange Act, and
(ii) accompanied by such other documents as the Note Registrar may require.

                  No service charge shall be made to a Holder for any
registration of transfer or exchange of Notes, but the Note Registrar may
require payment of a sum sufficient to cover any

                                       5

<PAGE>

tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Notes, other than exchanges pursuant to
Section 2.4 or 9.6 not involving any transfer.

                  The Note Registrar shall not register the transfer of a
Definitive Note unless the Indenture Trustee has received a representation
letter (in form and substance satisfactory to the Indenture Trustee) from the
prospective transferee to the effect that either such transferee (i) is not
acquiring such Note for, or with the assets of, an employee benefit plan or
other retirement arrangement that is subject to Section 406 of ERISA or Section
4975 of the Code or any substantially similar law ("Similar Law"), or any entity
deemed to hold the plan assets of the foregoing (collectively, "Benefit Plans"),
or (ii) its acquisition and holding of such Note for, or with the assets of, a
Benefit Plan will not result in a non-exempt prohibited transaction under
Section 406 of ERISA or Section 4975 of the Code which is not covered under
Prohibited Transaction Class Exemption ("PTCE") 84-14, PTCE 90-1, PTCE 91-38,
PTCE 95-60, PTCE 96-23 or some other applicable exemption, and will not result
in a non-exempt violation of any Similar Law. Each Note Owner, by acceptance of
a beneficial interest in a Book-Entry Note, will be deemed to make one of the
foregoing representations.

                  SECTION 2.4. Mutilated, Destroyed, Lost or Stolen Notes. If
(i) any mutilated Note is surrendered to the Note Registrar, or the Note
Registrar receives evidence to its satisfaction of the destruction, loss or
theft of any Note, and (ii) there is delivered to the Issuer, the Indenture
Trustee, the Note Registrar and the Insurer such security or indemnity as may be
required by it to hold the Issuer, the Indenture Trustee, the Note Registrar and
the Insurer 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 (such requirement
shall not be deemed to create a duty in the Indenture Trustee to monitor the
compliance by the Issuer with Section 8-405); 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, or shall have been called for
redemption, the Issuer may, instead of issuing a replacement Note, direct the
Indenture Trustee, in writing, to pay such destroyed, lost or stolen Note when
so due or payable or upon the Redemption Date 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, the Indenture Trustee and
the Insurer 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, the Indenture Trustee or
the Insurer in connection therewith.

                  Upon the issuance of any replacement Note under this Section,
the Issuer may require the payment by the Holder of such Note of a sum
sufficient to cover any tax or other

                                       6

<PAGE>

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 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 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 2.5. Persons Deemed Owners. Prior to due presentment
for registration of transfer of any Note, the Issuer, the Indenture Trustee and
the Insurer and any agent of the Issuer, the Indenture Trustee, the Note
Registrar and the Insurer shall treat the Person in whose name any Note is
registered (as of the Record Date) 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 none of
the Issuer, the Insurer, the Note Registrar, the Indenture Trustee nor any agent
of the Issuer, the Insurer , the Note Registrar or the Indenture Trustee shall
be affected by notice to the contrary.

                  SECTION 2.6. Payment of Principal and Interest; Defaulted
Interest.

                  (a) The Notes shall accrue interest as provided herein, and
such amount shall be payable on each Payment Date as specified herein. Any
installment of interest or principal, if any, payable on any Note which is
punctually paid or duly provided for by the Issuer on the applicable Payment
Date shall be paid to the Person in whose name such Note (or one or more
Predecessor Notes) is registered on the Record Date, (1) with respect to
Book-Entry Notes, by wire transfer in immediately available funds to the account
designated by the nominee of the Clearing Agency (initially, such nominee to be
Cede & Co.), and (2) if Definitive Notes have been issued pursuant to Section
2.11, then by check mailed first class, postage prepaid, (or upon the request of
a Holder holding Notes having denominations aggregating at least $1,000,000 and
received by the Indenture Trustee at least five Business Days prior to the
related Record Date, by wire transfer) to such Person who's name appears on the
Note Register on such Record Date; provided that the final installment of
principal payable with respect to such Note on a Payment Date or on the Final
Scheduled Payment Date (except for the Redemption Price for any Note called for
redemption pursuant to Section 10.1) shall be payable by check or draft upon
presentation of the Note to the Indenture Trustee. The funds represented by any
such checks returned undelivered shall be held in accordance with Section 3.3.

                  (b) Upon written notice from the Issuer, the Indenture Trustee
shall notify the Person in whose name a Note is registered at the close of
business on the Record Date preceding the Payment Date on which the Issuer
expects that the final installment of principal of and interest on such Note
will be paid. Such notice shall be mailed or transmitted by facsimile prior to
such final Payment Date and shall specify that such final installment will be
payable only upon presentation and surrender of such Note and shall specify the
place where such Note may

                                       7

<PAGE>

be presented and surrendered for payment of such installment. Notices in
connection with redemptions of Notes shall be mailed to Noteholders as provided
in Section 10.2.

                  (c) If the Issuer defaults in a payment of interest on the
Notes, the Issuer shall pay defaulted interest (plus interest on such defaulted
interest to the extent lawful) at the Note Rate to the extent lawful. The Issuer
may pay such defaulted interest to the Persons who are Noteholders on a
subsequent special Record Date, which date shall be at least five Business Days
prior to the Payment Date. The Issuer shall fix or cause to be fixed any such
special Record Date and Payment Date, and, at least 15 days before any such
special Record Date, the Issuer shall mail to each Noteholder, the Insurer and
the Indenture Trustee a notice that states the special Record Date, the Payment
Date and the amount of defaulted interest to be paid.

                  (d) Promptly following the date on which all principal of and
interest on the Notes has been paid in full and the Notes have been surrendered
to the Indenture Trustee, the Indenture Trustee shall, upon written notice from
the Depositor of the amounts, if any, that the Insurer has paid in respect of
the Notes under the Policy or otherwise which has not been reimbursed to the
Insurer, deliver such surrendered Notes to the Insurer to the extent not
previously canceled or destroyed.

                  SECTION 2.7. Cancellation. Subject to Section 2.6(d), 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 canceled by the
Indenture Trustee. Subject to Section 2.6(d), 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 canceled by the Indenture Trustee.
No Notes shall be authenticated in lieu of or in exchange for any Notes canceled
as provided in this Section, except as expressly permitted by this Indenture.
Subject to Section 2.6(d), all canceled 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 Order that
they be returned to it; provided that such Issuer Order is timely and the Notes
have not been previously disposed of by the Indenture Trustee.

                  SECTION 2.8. Release of Collateral. The Indenture Trustee
shall, on or after the Termination Date, release any remaining portion of the
Collateral from the lien created by this Indenture and deposit in the
Distribution Account any funds then on deposit in any other Account. The
Indenture Trustee shall release property from the lien created by this Indenture
pursuant to this Section 2.8 only upon receipt of an Issuer Request by it
accompanied by an Officer's Certificate and an Opinion of Counsel (which shall
also be addressed to the Insurer) and (if required by the TIA) Independent
Certificates in accordance with TIA Sections 314(c) and 314(d)(1) meeting the
applicable requirements of Section 11.1.

                  SECTION 2.9. 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 or its
custodian, the initial Clearing Agency, by, or on behalf of, the Issuer. Such
Notes shall initially be registered on the Note Register in the name of Cede &
Co., the nominee of the initial Clearing Agency, and no Note Owner will receive
a Definitive

                                       8

<PAGE>

Note representing such Note Owner's interest in such Note, except as provided in
Section 2.11. Unless and until definitive, fully registered Notes (the
"Definitive Notes") have been issued to Note Owners pursuant to Section 2.11:

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

                           (ii) the Note Registrar and the Indenture Trustee
         shall be entitled to deal with the Clearing Agency 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 Note
         Owners;

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

                           (iv) the rights of Note Owners shall be exercised
         only through the Clearing Agency and shall be limited to those
         established by law and agreements between such Note Owners and the
         Clearing Agency and/or the Clearing Agency Participants. Unless and
         until Definitive Notes are issued pursuant to Section 2.11, the initial
         Clearing Agency will make book-entry transfers among the Clearing
         Agency Participants and receive and transmit payments of principal of
         and interest on the Notes to such Clearing Agency Participants;

                           (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 Outstanding Amount of
         the Notes, the Clearing Agency shall be deemed to represent such
         percentage only to the extent that it has received instructions to such
         effect from Note Owners and/or Clearing Agency Participants owning or
         representing, respectively, such required percentage of the beneficial
         interest in the Notes and has delivered such instructions to the
         Indenture Trustee; and

                           (vi) Note Owners may receive copies of any reports
         sent to Noteholders pursuant to this Indenture, upon written request,
         together with a certification that they are Note Owners and payment of
         reproduction and postage expenses associated with the distribution of
         such reports, from the Indenture Trustee at the Corporate Trust Office.

                  SECTION 2.10. Notices to Clearing Agency. Whenever a notice or
other communication to the Noteholders is required under this Indenture, unless
and until Definitive Notes shall have been issued to Note Owners pursuant to
Section 2.11, the Indenture Trustee shall give all such notices and
communications specified herein to be given to Holders of the Notes to the
Clearing Agency, and shall have no obligation to the Note Owners.

                  SECTION 2.11. Definitive Notes. If (i) the Clearing Agency
advises the Indenture Trustee in writing that the Clearing Agency is no longer
willing or able to properly discharge its responsibilities with respect to the
Notes, and the Depositor or the Indenture Trustee is unable to locate a
qualified successor, (ii) the Depositor, with the consent of the applicable
Clearing Agency participants, elects to terminate the book-entry system through
the

                                       9

<PAGE>

Clearing Agency or (iii) with the consent of the Insurer after the occurrence of
a Rapid Amortization Event, Note Owners representing beneficial interests
aggregating at least a majority of the Outstanding Amount of the Notes advise
the Indenture Trustee through the Clearing Agency in writing that the
continuation of a book entry system through the Clearing Agency is no longer in
the best interests of the Note Owners, then the Clearing Agency shall notify all
Note Owners and the Indenture Trustee of the occurrence of any such event and of
the availability of Definitive Notes to Note Owners requesting the same. Upon
surrender to the Indenture Trustee of the typewritten Note or Notes representing
the Book-Entry Notes by the Clearing Agency, accompanied by registration
instructions, the Issuer shall execute and the Indenture Trustee shall
authenticate the Definitive Notes in accordance with the instructions of the
Clearing Agency. 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 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.

                                   ARTICLE III

             Covenants; Representations and Warranties of the Issuer

                  SECTION 3.1. Payment of Principal and Interest. The Issuer
will duly and punctually pay the principal of and interest on the Notes in
accordance with the terms of the Notes and this Indenture. The Notes are
nonrecourse debt obligations of the Issuer and shall be limited in right of
payment to amounts available from the Issuer as provided in this Indenture and
the Issuer shall not otherwise be liable for payments on the Notes. No person
shall be personally liable for any amounts payable under the Notes. Amounts
properly withheld under the Code by any Person from a payment to any Noteholder
of interest and/or principal shall be considered as having been paid by the
Issuer to such Noteholder for all purposes of this Indenture.

                  SECTION 3.2. Maintenance of Office or Agency. The Issuer will
maintain an office or agency where Notes may be surrendered for registration,
transfer or exchange of the Notes, and 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 at its corporate office in
Minneapolis, Minnesota to serve as its agent for the foregoing purposes. The
Issuer will give prompt written notice to the Indenture Trustee of the location,
and of any change in the location, of any such office or agency. If at any time
the Issuer shall fail to maintain any such office or agency or shall fail to
furnish the Indenture Trustee with the address thereof, such surrenders, notices
and demands may be made or served at the Corporate Trust Office of the Indenture
Trustee, and the Issuer hereby appoints the Indenture Trustee as its agent to
receive all such surrenders, notices and demands.

                  SECTION 3.3. Money for Payments to be Held in Trust. The
Issuer will cause each Note Paying Agent other than the Indenture Trustee to
execute and deliver to the Indenture Trustee and the Insurer an instrument in
which such Note Paying Agent shall agree with the Indenture Trustee (and if the
Indenture Trustee acts as Note Paying Agent, it hereby so agrees), subject to
the provisions of this Section, that such Note Paying Agent will:

                                       10

<PAGE>

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

                           (ii) give the Indenture Trustee (unless the Indenture
         Trustee is acting as Note Paying Agent) and the Insurer written notice
         of any default by the Issuer (or any other obligor upon the Notes) of
         which it has actual knowledge in the making of any payment required to
         be made with respect to the Notes;

                           (iii) at any time during the continuance of any such
         default, upon the written request of the Indenture Trustee (unless the
         Indenture Trustee is acting as Note Paying Agent) with the consent of
         the Insurer, if the Insurer is the Controlling Party, forthwith pay to
         the Indenture Trustee all sums so held in trust by such Note Paying
         Agent;

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

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

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

                  Subject to applicable laws with respect to the escheat of
funds, any money held by the Indenture Trustee or any Note Paying Agent in trust
for the payment of any amount due with respect to any Note and remaining
unclaimed for two years after such amount has become due and payable shall be
discharged from such trust and be paid to the Issuer, with the prior consent of
the Insurer, on Issuer Request, and shall be deposited by the Indenture Trustee
in the Distribution Account; 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, the Insurer or such Note Paying Agent with respect to
such trust money shall thereupon cease; provided, however, that if such money or
any portion thereof had been previously deposited by the Insurer with the
Indenture Trustee for the payment of principal or interest on the Notes, to the
extent any amounts are owing to the Insurer, such amounts shall be paid promptly
to the Insurer upon receipt of a written request by the Insurer to such effect.

<PAGE>

                  SECTION 3.4. Existence. The Issuer will keep in full effect
its existence, rights and franchises as a statutory trust under the laws of the
State of Delaware (unless it becomes, or any successor Issuer hereunder is or
becomes, organized under the laws of any other state or of the United States of
America, in which case the Issuer will keep in full effect its existence, rights
and franchises under the laws of such other jurisdiction) and will obtain and
preserve its qualification to do business in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Indenture, the Collateral, the Notes, and each other
instrument or agreement included in the Collateral.

                  SECTION 3.5. Protection of Collateral. The Issuer intends the
security interest granted pursuant to this Indenture in favor of the Issuer
Secured Parties to be prior to all other liens in respect of the Collateral and
the Issuer shall take all actions necessary to obtain and maintain, in favor of
the Indenture Trustee, for the benefit of the Issuer Secured Parties, a first
lien on and a first priority, perfected security interest in the Collateral. The
Issuer will from time to time prepare (or shall cause to be prepared), execute
and deliver all such supplements and amendments hereto and all such financing

                           (i) Grant more effectively all or any portion of the
         Collateral;

                           (ii) maintain or preserve the lien and security

         upon the Collateral when due.

The Issuer hereby designates the Indenture Trustee its agent and
attorney-in-fact to execute any financing statement, continuation statement or
other instrument required pursuant to this Section; provided that, such
designation shall not relieve the Issuer of its obligation to make any such
filing, nor be deemed to create a duty in the Indenture Trustee to prepare any
financing statement, continuation statement or other instrument or monitor the
compliance of the Issuer with respect to its duties under this Section 3.5 or
the adequacy of any financing statement, continuation statement or other
instrument prepared by the Issuer.

                  SECTION 3.6. Opinions as to Collateral.

such counsel, such actions have been taken with respect to the recording and
filing of this Indenture, any indentures supplemental hereto, and any other
requisite documents, and with respect to the execution and filing of any
financing statements and continuation statements, as are necessary to perfect
and make effective the first priority lien and security interest in the
Collateral in favor of the Indenture Trustee, for the benefit of the Issuer
Secured Parties, created by this Indenture, subject to the exceptions and
qualifications set forth in such Opinion of Counsel.

                  (b) Within 90 days after the beginning of each calendar year,

and any other requisite documents and with respect to the execution and filing
of any financing statements and continuation statements as are necessary to
maintain the lien and security interest created by this Indenture in the
Collateral and reciting the details of such action or stating that in the
opinion of such counsel, no such action is necessary to maintain such lien and
security interest. Such Opinion of Counsel shall also describe the recording,
filing, re-recording and refiling of this Indenture, any indentures supplemental
hereto and any other requisite documents and the execution and filing of any
financing statements and continuation statements that will, in the opinion of
such counsel, be required to maintain the lien and security interest of this

                  SECTION 3.7. Performance of Obligations; Servicing of Mortgage
Loans.

                  (a) The Issuer will not take any action and will use its best
efforts not to permit any action to be taken by others that would release any
Person from any of such Person's material covenants or obligations under any
instrument or agreement included in the Collateral or that would result in the
amendment, hypothecation, subordination, termination or discharge of, or impair
the validity or effectiveness of, any such instrument or agreement, except as
ordered by any bankruptcy or other court or as expressly provided in this
Indenture, the Basic Documents or such other instrument or agreement.

                  (b) The Issuer may contract with other Persons acceptable to
the Insurer to assist it in performing its duties under this Indenture, and any
performance of such duties by a Person identified to the Indenture Trustee and
the Insurer in an Officer's Certificate of the Issuer shall be deemed to be
action taken by the Issuer. Initially, the Issuer has contracted with the
Depositor to assist the Issuer in performing its duties under this Indenture.

                  (c) The Issuer will punctually perform and observe all of its
obligations and agreements contained in this Indenture, the Basic Documents and

accordance with and within the time periods provided for herein and therein.
Except as otherwise expressly provided therein, the Issuer shall not waive,
amend, modify, supplement or terminate any Basic Document or any provision
thereof without the consent of the Indenture Trustee and the Insurer.

                  (d) If a Responsible Officer of the Owner Trustee shall have
actual knowledge of the occurrence of an Event of Servicing Termination under
the Sale and Servicing Agreement, the Issuer shall promptly notify the Indenture
Trustee, the Insurer and the Rating Agencies thereof in accordance with Section
11.4, and shall specify in such notice the action, if any, the Issuer is taking
at the direction of the Controlling Party in respect of such default. If an
Event of Servicing Termination shall arise from the failure of the Servicer to
perform any of its duties or obligations under the Sale and Servicing Agreement
with respect to the Mortgage Loans, the Issuer shall take all reasonable steps
available to it to remedy such failure.

                  (e) The Issuer agrees that it will not waive timely
performance or observance by the Servicer or the Depositor of their respective
duties under the Basic Documents (x) without the prior consent of the Insurer or

         or the Basic Documents, sell, transfer, exchange or otherwise dispose
         of any of the properties or assets of the Issuer, including those
         included in the Collateral (but excluding any Mortgage Loans removed
         from the Pool pursuant to Section 2.07 of the Sale and Servicing
         Agreement), without the consent of the Insurer (which consent may not
         be unreasonably withheld) provided, that if an Insurer Default has
         occurred and is continuing the Noteholders representing 66-2/3% of the
         Outstanding Amount may direct the Indenture Trustee to sell or dispose
         of the Collateral.

                           (ii) claim any credit on, or make any deduction from
         the principal or interest payable in respect of, the Notes (other than
         amounts properly withheld from such payments under the Code) or assert
         any claim against any present or former Noteholder by reason of the
         payment of the taxes levied or assessed upon any part of the
         Collateral; or

                           (iii) (A) permit the validity or effectiveness of
         this Indenture to be impaired, or permit the lien in favor of the
         Indenture Trustee created by this Indenture to be amended,
         hypothecated, subordinated, terminated or discharged, or permit any
         Person to be released from any covenants or obligations with respect to
         the Notes under this Indenture except as may be expressly permitted
         hereby, (B) permit any lien, charge, excise, claim, security interest,
         mortgage or other encumbrance (other than the lien of this Indenture)
         to be created on or extend to or otherwise arise upon or burden the
         Collateral or any part thereof or any interest therein or the proceeds
         thereof (other than tax liens, mechanics' liens and other liens that
         arise by operation of law, in each case on a Mortgaged Property and
         arising solely as a result of an action or omission of the related
         obligor), (C) permit the lien of this Indenture not to constitute a
         valid first priority (other than with respect to any such tax,
         mechanics' or other lien) security interest in the Collateral or (D)
         amend, modify or fail to comply with the provisions of the Basic
         Documents without the prior written consent of the Insurer, which
         consent may not be unreasonably withheld.

         conditions and covenants under this Indenture throughout such year, or,

Residual Certificates, (ii) the Notes, (iii) obligations owing from time to time
to the Insurer under the Insurance Agreement and (iv) any other indebtedness
permitted by or arising under the Basic Documents, except that the Issuer shall
not incur any indebtedness that would cause it, or any portion thereof, to be
treated as a "taxable mortgage pool" under Section 7701 of the Code. The
proceeds of the Notes and the Residual Certificates shall be used exclusively to
fund the Issuer's purchase of the Mortgage Loans and the other assets specified

transactional and start-up expenses.

                  SECTION 3.13. Servicer's Obligations. The Issuer shall cause

         Indenture Trustee pursuant to this Indenture, the Issuer has not
         pledged, assigned, sold, granted a security interest in, or otherwise

                  In the event the Indenture Trustee shall receive conflicting
or inconsistent requests and indemnity from two or more groups of Holders of
Notes, each representing less than a majority of the Outstanding Amount of the
Notes, the Indenture Trustee shall take direction from the group providing
indemnity and representing the greater percentage of the Outstanding Amount of
the Notes, notwithstanding any other provisions of this Indenture.

                  SECTION 5.3. Unconditional Rights of Noteholders To Receive
Principal and Interest. Notwithstanding any other provisions in this Indenture,
the Holder of any Note shall have the right, which is absolute and
unconditional, to receive payment of the principal of and interest, if any, on
such Note on or after the respective due dates thereof expressed in such Note or
in this Indenture (or, in the case of redemption, on or after the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
right shall not be impaired without the consent of such Holder.

                  SECTION 5.4. Restoration of Rights and Remedies. If the
Indenture Trustee or any Noteholder has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, then and in every such case the Issuer, the
Insurer, 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, the Insurer and the Noteholders shall continue as though no
such proceeding had been instituted.

                  SECTION 5.5. Rights and Remedies Cumulative. No right or
remedy herein conferred upon or reserved to the Controlling Party or to the
related 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 5.6. Delay or Omission Not a Waiver. No delay or
omission of the Indenture Trustee, the Insurer or any Holder of any Note to
exercise any right or remedy accruing upon any Rapid Amortization Event shall
impair any such right or remedy or constitute a waiver of any such Rapid
Amortization Event or an acquiescence therein. Every right and remedy given by
this Article V or by law to the Indenture Trustee, the Insurer or to the
Noteholders may be exercised from time to time, and as often as may be deemed
expedient, by the Indenture Trustee, the Insurer or by the Noteholders, as the
case may be.

                  SECTION 5.7. Control by Insurer and Noteholders. The Insurer
(or, if an Insurer Default shall have occurred and is continuing, Holders of a
majority of the Outstanding Amount of the Notes) shall have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Indenture Trustee pursuant to Section 12.2 hereof

                                       20

<PAGE>

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) the Indenture Trustee may take any other action
         deemed proper by the Indenture Trustee that is not inconsistent with
         such direction;

provided, however, that, subject to Section 6.1, the Indenture Trustee need not
take any action that it determines might involve it in liability or might
materially adversely affect the rights of any Noteholders not consenting to such
action.

                  SECTION 5.8. Undertaking for Costs. All parties to this
Indenture agree, and each Holder of any Note by such Holder'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 and
expenses, 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 shall not apply to (a) any suit instituted by the
Indenture Trustee, (b) any suit instituted by the Insurer, any Noteholder, or
group of Noteholders with the prior written consent of the Insurer (so long as
no Insurer Default has occurred), in each case holding in the aggregate more
than 10% of the Outstanding Amount 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 (or, in the case of redemption, on or after the Redemption Date).

                  SECTION 5.9. 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
will not hinder, delay or impede the execution of any power herein granted to
the Indenture Trustee, but will suffer and permit the execution of every such
power as though no such law had been enacted.

                  SECTION 5.10. Action on Notes. The Indenture Trustee's right
to seek and recover judgment on the Notes or under this Indenture shall not be
affected by the seeking, obtaining or application of any other relief under or
with respect to this Indenture. Neither the lien of this Indenture nor any
rights or remedies of the Indenture Trustee, the Insurer or the Noteholders
shall be impaired by the recovery of any judgment by the Indenture Trustee or
the Insurer against the Issuer or by the levy of any execution under such
judgment upon any portion of the Collateral or upon any of the assets of the
Issuer.

                  SECTION 5.11. Performance and Enforcement of Certain
Obligations.

                                       21

<PAGE>

                  (a) Promptly following a request from the Indenture Trustee
(at the direction of the Insurer) to do so and at the Depositor's expense, the
Issuer agrees to take all such lawful action as the Indenture Trustee may
request to compel or secure the performance and observance by the Depositor and
the Servicer, as applicable, of each of their obligations to the Issuer under or
in connection with the Sale and Servicing Agreement in accordance with the terms
thereof, and to exercise any and all rights, remedies, powers and privileges
lawfully available to the Issuer under or in connection with the Sale and
Servicing Agreement to the extent and in the manner directed by the Indenture
Trustee, including the transmission of notices of default on the part of the
Depositor or the Servicer thereunder and the institution of legal or
administrative actions or proceedings to compel or secure performance by the
Depositor or the Servicer of each of their obligations under the Sale and
Servicing Agreement.

                  (b) If a Rapid Amortization Event has occurred and is
continuing, the Indenture Trustee, with the consent of the Insurer, may, and, at
the written direction of the Insurer (or, if an Insurer Default has occurred and
is continuing, the Holders of 66 2/3% of the Outstanding Amount of the Notes)
shall, exercise all rights, remedies, powers, privileges and claims of the
Issuer against the Depositor or the Servicer under or in connection with the
Sale and Servicing Agreement, including the right or power to take any action to
compel or secure performance or observance by the Depositor or the Servicer of
each of their obligations to the Issuer thereunder and to give any consent,
request, notice, direction, approval, extension or waiver under the Sale and
Servicing Agreement, and any right of the Issuer to take such action shall be
suspended.

                  SECTION 5.12. Subrogation. The Indenture Trustee shall receive
as attorney-in-fact of each Noteholder any Insured Amounts or Preference Amounts
from the Insurer pursuant to the Policy. Any and all Insured Amounts and
Preference Amounts disbursed by the Indenture Trustee from claims made under the
Policy shall not be considered payment by the Issuer, and shall not discharge
the obligations of the Issuer with respect thereto. The Insurer shall, to the
extent it makes any payment with respect to the Notes, become subrogated to the
rights of the recipient of such payments to the extent of such payments. Subject
to and conditioned upon any payment with respect to the Notes by or on behalf of
the Insurer, the Indenture Trustee shall assign to the Insurer all rights to the
payment of interest or principal with respect to the Notes which are then due
for payment to the extent of all payments made by the Insurer.

                  SECTION 5.13. Preference Claims.

                  (a) In the event that the Indenture Trustee has received a
certified copy of an order of the appropriate court that any payment of
principal and interest on a Note has been avoided in whole or in part as a
preference payment under applicable bankruptcy law, the Indenture Trustee shall
so notify the Insurer, shall comply with the provisions of the Policy to obtain
payment by the Insurer of such avoided payment, and shall, at the time it
provides notice to the Insurer, notify Holders of the Notes by mail that, in the
event that any Noteholder's payment is so recoverable, such Noteholder will be
entitled to payment pursuant to the terms of the Policy. The Indenture Trustee
shall furnish to the Insurer at its written request, the requested records it
holds in its possession evidencing the payments of principal of and interest on
Notes, if any, which have been made by the Indenture Trustee and subsequently
recovered from

                                       22

<PAGE>

Noteholders and the dates on which such payments were made. Pursuant to the
terms of the Policy, the Insurer will make such payment on behalf of the related
Noteholder to the receiver, conservator, debtor-in-possession or trustee in
bankruptcy named in the final order of the court exercising jurisdiction on
behalf of the Noteholders and not to the Indenture Trustee, any Noteholder
directly (unless such Noteholder has returned principal or interest paid on the
Notes to such receiver or trustee in bankruptcy, in which case the Insurer shall
make such payment to the Indenture Trustee for payment to such Noteholder in
accordance with the terms of the Policy).

                  (b) The Indenture Trustee shall promptly notify the Insurer of
any proceeding or the institution of any action (of which the Indenture Trustee
has actual knowledge) seeking the avoidance as a preferential transfer under
applicable bankruptcy, insolvency, receivership, rehabilitation or similar law
(a "Preference Claim") of any distribution made with respect to the Notes. Each
Holder, by its purchase of Notes, and the Indenture Trustee hereby agree that so
long as an Insurer Default shall not have occurred and be continuing, the
Insurer may at any time during the continuation of any proceeding relating to a
Preference Claim direct all matters relating to such Preference Claim,
including, without limitation, (i) the direction of any appeal of any order
relating to any Preference Claim and (ii) the posting of any surety, supersedes
or performance bond pending any such appeal at the expense of the Insurer, but
subject to reimbursement as provided in the Insurance Agreement. In addition,
and without limitation of the foregoing, as set forth in Section 5.12, the
Insurer shall be subrogated to, and each Noteholder and the Indenture Trustee
hereby delegate and assign, to the fullest extent permitted by law, the rights
of the Indenture Trustee and each Noteholder in the conduct of any proceeding
with respect to a Preference Claim, including, without limitation, all rights of
any party to an adversary proceeding action with respect to any court order
issued in connection with any such Preference Claim. All actions taken under
this Section 5.13(b) by the Indenture Trustee shall be taken in accordance with
the terms of the Policy.

                  SECTION 5.14. Noteholder Rights. Each Noteholder by the
acceptance of its Note agrees that, so long as no Insurer Default has occurred
and is continuing, the Insurer shall be treated by the Issuer, the Seller, the
Depositor, the Servicer, the Owner Trustee and the Indenture Trustee as if the
Insurer were the Holder of the Note for the purpose of the giving of any
consent, the making of any direction or the exercise of any voting or other
control rights otherwise given to the Noteholder hereunder without any further
consent of the Noteholder. So long as no Insurer Default has occurred and is
continuing, the Noteholders may only exercise such rights with the consent of
the Insurer.

                  SECTION 5.15. Insurer's Rights Regarding Actions, Proceedings
or Investigations. Until all Notes have been paid in full, all amounts owed to
the Insurer have been paid in full, the Insurance Agreement has terminated and
the Policy has been returned to the Insurer for cancellation, the following
provisions shall apply:

                  (a) Unless an Insurer Default resulting from the failure of
the Insurer to make payments under the Policy has occurred or is continuing,
notwithstanding anything contained herein or in the other Basic Documents to the
contrary, the Insurer shall have the right to participate in, to direct the
enforcement or defense of, and, at the Insurer's sole option, to institute or
assume the defense of, any action, proceeding or investigation that could
adversely

                                       23

<PAGE>

affect the Issuer, the Collateral, the Trust Property or the rights or
obligations of the Insurer hereunder or under the Policy or the Basic Documents,
including (without limitation) any insolvency or bankruptcy proceeding in
respect of the Servicer, the Seller, the Depositor, the Issuer or any affiliate
thereof. Following notice to the Indenture Trustee and subject to the preceding
sentence, the Insurer shall have exclusive right to determine, in its sole
discretion, the actions necessary to preserve and protect the Issuer, the
Collateral, and the Trust Property. All costs and expenses of the Insurer in
connection with such action, proceeding or investigation, including (without
limitation) any judgment or settlement entered into affecting the Insurer or the
Insurer's interests, shall be included in the Reimbursement Amount.

                  (b) In connection with any action, proceeding or investigation
that could adversely affect the Issuer, the Collateral, the Trust Property or
the rights or obligations of the Insurer hereunder or under the Policy or the
Basic Documents, including (without limitation) any insolvency or bankruptcy
proceeding in respect of the Servicer, the Seller, the Depositor, the Issuer or
any affiliate thereof, the Indenture Trustee hereby agrees to cooperate with,
and to take such action as directed by, the Insurer, including (without
limitation) entering into such agreements and settlements as the Insurer shall
direct, in its sole discretion, without the consent of any Noteholder.

                  (c) The Indenture Trustee hereby agrees to provide to the
Insurer prompt written notice of any action, proceeding or investigation of
which a Responsible Officer has received notice or has actual knowledge that
names the Issuer or the Indenture Trustee as a party or that could adversely
affect the Issuer, the Collateral, the Trust Property or the rights or
obligations of the Insurer hereunder or under the Policy or the Basic Documents,
including (without limitation) any insolvency or bankruptcy proceeding in
respect of the Servicer, the Seller, the Depositor, the Trust or any affiliate
thereof.

                  (d) Notwithstanding anything contained herein or in any of the
other Basic Documents to the contrary, the Indenture Trustee shall not, without
the Insurer's prior written consent or unless directed by the Insurer, undertake
or join any litigation or agree to any settlement of any action, proceeding or
investigation affecting the Issuer, the Collateral, the Trust Property or the
rights or obligations of the Insurer hereunder or under the Policy or the Basic
Documents.

                  (e) Each Noteholder, by acceptance of its Note, and the
Indenture Trustee agree that the Insurer shall have such rights as set forth in
this Section, which are in addition to any rights of the Insurer pursuant to the
other provisions of the Basic Documents, that the rights set forth in this
Section may be exercised by the Insurer, in its sole discretion, without the
need for the consent or approval of any Noteholder or the Indenture Trustee,
notwithstanding any other provision contained herein or in any of the other
Basic Documents, and that nothing contained in this Section shall be deemed to
be an obligation of the Insurer to exercise any of the rights provided for
herein.

                              The Indenture Trustee

                  SECTION 6.1. Duties of Indenture Trustee.

                  (a) If a Rapid Amortization Event of which a Responsible
Officer of the Indenture Trustee has received notice or has actual knowledge has
occurred and is continuing, the Indenture Trustee shall exercise the rights and
powers vested in it by this Indenture and the Basic Documents and use the same
degree of care and skill in its exercise as a prudent person would exercise or
use under the circumstances in the conduct of such person's own affairs;

                  (b) Except during the continuance of a Rapid Amortization
Event of which a Responsible Officer of the Indenture Trustee has notice or
actual knowledge:

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

                           (ii) in the absence of bad faith on its part, the
         Indenture Trustee may conclusively rely, as to the truth of the
         statements and the correctness of the opinions expressed therein, upon
         certificates or opinions furnished to the Indenture Trustee and
         conforming to the requirements of this Indenture; however, the
         Indenture Trustee shall examine the certificates and opinions to
         determine whether or not they conform on their face 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, its negligent failure to perform its material obligations in
compliance with this Agreement, or any liability which would be imposed by
reason of its willful misfeasance or bad faith; except that:

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

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

                           (iii) the Indenture Trustee shall not be liable with
         respect to any action it takes or omits to take in reasonable good
         faith in accordance with a direction received by it pursuant to the
         terms herein; and

                           (iv) the Indenture Trustee shall not be charged with
         knowledge of any Rapid Amortization Event or any failure by the
         Servicer to comply with the obligations of the Servicer in the Sale and
         Servicing Agreement unless a Responsible Officer of the Indenture
         Trustee at the Corporate Trust Office obtains actual knowledge of such
         Rapid Amortization Event or failure or the Indenture Trustee receives
         written notice of such

                                       25

<PAGE>

         Rapid Amortization Event or failure from the Servicer, the Insurer or
         the Holders of Notes evidencing more than 50% of the Outstanding
         Amount.

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

                  (e) No provision of this Indenture shall require the Indenture
Trustee to expend or risk its own funds or otherwise incur financial liability
in the performance of any of its duties hereunder or in the exercise of any of
its rights or powers (including, but not limited to, its powers and obligations
to sell, dispose of, or otherwise liquidate, the Collateral pursuant to Section
12.2), if it shall have reasonable grounds to believe that repayment of such
funds or indemnity reasonably satisfactory to it against such risk or liability
is not reasonably assured to it.

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

                  (g) The Indenture Trustee shall, upon three Business Days'
prior written notice to the Indenture Trustee, permit any representative of the
Insurer, during the Indenture Trustee's normal business hours, to examine all
books of account, records, reports and other papers of the Indenture Trustee
relating to the Notes, to make copies and extracts (at the expense of the party
requesting such copies or extracts) therefrom and to discuss the Indenture
Trustee's affairs and actions, as such affairs and actions relate to the
Indenture Trustee's duties with respect to the Notes, with the Indenture
Trustee's officers and employees responsible for carrying out the Indenture
Trustee's duties with respect to the Notes.

                  (h) The Indenture Trustee shall, and hereby agrees that it
will, perform all of the obligations and duties required of it under the Sale
and Servicing Agreement.

                  (i) The Indenture Trustee shall, and hereby agrees that it
will, hold the Policy in trust, and will hold any proceeds of any claim on the
Policy in trust solely for the use and benefit of the Noteholders.

                  (j) In no event shall Wells Fargo Bank, N.A., in any of its
capacities hereunder, be deemed to have assumed any duties of the Owner Trustee
under the Delaware Statutory Trust Statute, common law, or (other than those
duties expressly assumed by the Indenture Trustee thereunder) the Trust
Agreement.

                  (k) The Indenture Trustee shall have no duty (A) to see to any
recording, filing, or depositing of this Indenture or any agreement referred to
herein or any financing statement or continuation statement evidencing a
security interest, or to see to the maintenance of any such recording or filing
or depositing or to any rerecording, refiling or redepositing of any thereof,
(B) to see to any insurance, (C) to see to the payment or discharge of any tax,
assessment, or other governmental charge or any lien or encumbrance of any kind
owing with respect to, assessed or levied against, any part of the Collateral or
(D) to confirm or verify the contents of any reports or certificates of the
Issuer, the Depositor or the Servicer delivered to the

                                       26

<PAGE>

Indenture Trustee pursuant to this Indenture reasonably believed by the
Indenture Trustee to be genuine and to have been signed or presented by the
proper party or parties.

                  SECTION 6.2. Rights of Indenture Trustee.

                  (a) The Indenture Trustee may conclusively rely on any
resolution, opinion of counsel, officer's certificate, certificate of auditors,
servicing officer's or any other certificate, statement, instrument, opinion,
report, notice, request, consent, order, appraisal, bond or other paper or
document reasonably believed by it to be genuine and to have been signed or
presented by the proper person. The Indenture Trustee need not investigate any
fact or matter stated in such document.

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

                  (c) The Indenture Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or
through agents or attorneys or a custodian or nominee and the Indenture Trustee
shall not be liable for the negligence of such agents, attorneys, custodians or
nominees appointed (i) with due care and (ii) with the consent of the Insurer,
which consent shall not be unreasonably withheld, delayed or denied.

                  (d) The Indenture Trustee shall not be liable for any action
it takes or omits to take in good faith which it believes to be authorized or
within its rights or powers; provided, however, that the Indenture Trustee's
conduct does not constitute willful misconduct, negligence or bad faith. The
Indenture Trustee shall not, in any event, be liable for any action, or failure
to act, of the Custodian if the Custodian is at any time not the same Person as
the Indenture Trustee.

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

                  (f) The Indenture Trustee shall be under no obligation to
institute, conduct or defend any litigation under this Indenture or in relation
to this Indenture, at the request, order or direction of any of the Holders of
Notes or the Controlling Party, pursuant to the provisions of this Indenture,
unless such Holders of Notes or the Controlling Party shall have offered to the
Indenture Trustee security or indemnity reasonably satisfactory to it against
the costs, expenses and liabilities that may be incurred therein or thereby;
provided, however, that the Indenture Trustee shall, subject to Section 6.1(e),
upon the occurrence of a Rapid Amortization Event of which a Responsible Officer
of the Indenture Trustee shall have received notice or have actual knowledge
(that has not been cured or waived), exercise the rights and powers vested in it
by this Indenture or the Sale and Servicing Agreement with reasonable care and
skill.

                  (g) The Indenture Trustee shall not be bound to make any
investigation into the facts or matters stated in any resolution, certificate,
statement, instrument, opinion, report,

                                       27

<PAGE>

notice, request, consent, order, approval, bond or other paper or document,
unless requested in writing to do so by the Insurer or by the Holders of Notes
evidencing not less than a majority of the Outstanding Amount thereof; provided,
however, that if the payment within a reasonable time to the Indenture Trustee
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Indenture Trustee, not
reasonably assured to the Indenture Trustee by the security afforded to it by
the terms of this Indenture or the Sale and Servicing Agreement, the Indenture
Trustee may require indemnity reasonably satisfactory to it against such cost,
expense or liability as a condition to so proceeding; the reasonable expense of
every such examination shall be paid by the Person making such request, or, if
paid by the Indenture Trustee shall be reimbursed by the Person making such
request upon demand.

                  (h) The Indenture Trustee shall not be accountable, shall have
no liability and makes no representation as to any acts or omissions hereunder
of the Servicer until such time as the Indenture Trustee may be required to act
as Servicer.

                  (i) The right of the Indenture Trustee to perform any
discretionary act enumerated in this Indenture shall not be construed as a duty,
and the Indenture Trustee shall not be answerable for other than its negligence
or willful misconduct in the performance of such act.

                  SECTION 6.3. 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. Any Note
Paying Agent, 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.

                  SECTION 6.4. 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 Collateral, the Trust Property or
the Notes, 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 6.5. Notice of Rapid Amortization Events and Events of
Servicing Termination. If a Rapid Amortization Period or an Event of Servicing
Termination occurs and is continuing and if a Responsible Officer of the
Indenture Trustee either has actual knowledge thereof, or has received written
notice of the existence thereof, the Indenture Trustee shall (i) promptly mail
to the Insurer notice of such event, and (ii) within 90 days after such
knowledge or notice occurs, mail to each Noteholder notice of such event. Except
in the case of a default in payment of principal of or interest on any Note, the
Indenture Trustee may withhold the notice to the Noteholders if and so long as
one of its Responsible Officers in good faith determines that withholding the
notice is in the interests of Noteholders; provided that the Indenture Trustee
shall not withhold any such notice to the Insurer.

                  SECTION 6.6. Reports by Indenture Trustee to Holders. Within a
reasonable period of time after the end of each calendar year, the Indenture
Trustee shall furnish to each Person who at any time during the calendar year
was a Holder of a Note, if requested in writing

                                       28

<PAGE>

by such Person, a statement containing the information set forth in clauses (ii)
and (v) above, in each case aggregated for such calendar year or applicable
portion thereof during which such Person was a Note Holder. Such obligation of
the Indenture Trustee shall be deemed to have been satisfied to the extent that
substantially comparable information shall be provided by the Indenture Trustee
pursuant to any requirements of the Code as from time to time in force.

                  SECTION 6.7. Compensation and Indemnity.

                  (a) Pursuant to Section 8.7 and subject to Section 6.10
herein, the Issuer shall, or shall cause the Depositor to, pay to the Indenture
Trustee from time to time compensation as agreed to in writing between the
Depositor and the Indenture Trustee for its services. The Indenture Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Issuer or, to the extent provided in the Sale and Servicing
Agreement, the Depositor, shall reimburse the Indenture Trustee for all
reasonable out-of-pocket expenses incurred or made by it, including, but not
limited to, costs of collection, in addition to the compensation for its
services. Such expenses shall include the reasonable compensation and expenses,
disbursements and advances of the Indenture Trustee's agents, counsel (including
internal counsel), accountants and experts (including internal experts). The
Issuer or, to the extent provided in the Sale and Servicing Agreement, the
Depositor and the Seller, shall indemnify the Indenture Trustee and its
respective officers, directors, employees and agents against any and all loss,
liability or expense (including attorneys' fees and expenses) incurred by each
of them in connection with the acceptance or the administration of this trust
and the performance of its duties hereunder or under any other Basic Document.
The Indenture Trustee shall notify the Issuer, the Depositor and the Seller
promptly of any claim for which it may seek indemnity. Failure by the Indenture
Trustee to so notify the Issuer, the Depositor and the Seller shall not relieve
the Issuer of its obligations hereunder or the Depositor or the Seller of their
obligations under Article VIII of the Sale and Servicing Agreement. The Issuer
shall or shall cause the Depositor and the Seller to defend the claim, the
Indenture Trustee may have separate counsel and the Issuer or, to the extent
provided in the Sale and Servicing Agreement, the Depositor and the Seller,
shall pay the fees and expenses of such counsel. Neither the Issuer nor the
Depositor nor the Seller need 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. Anything is
this Indenture to the contrary notwithstanding, in no event shall the Indenture
Trustee be liable for special, indirect or consequential loss or damage of any
kind, whatsoever (including but not limited to lost profits), even if the
Indenture Trustee has been advised of the likelihood of such loss or damage and
regardless of the form of action.

                  (b) The Issuer's, the Depositor's and the Seller's payment
obligations to the Indenture Trustee (including, without limitation, the
indemnity obligations set forth above) shall also apply to the Indenture Trustee
in its capacity as Custodian, subject to the Indenture Trustee Expense Limit. In
the event that the Indenture Trustee is required to become the successor
Servicer, the out of pocket costs and expenses of the Indenture Trustee in
connection with the transfer of servicing shall also be reimbursable as set
forth above without regard to the Indenture Trustee Expense Limit. In addition,
in the event of any loss, liability or expense (including attorneys' fees and
expenses) incurred by the Indenture Trustee (including the Indenture Trustee in
the capacity as successor Servicer) arising out of a breach of the Seller's
representations set

                                       29

<PAGE>

forth in clause (xxxii), (xxxiii), (xxxiv), (xxxv) or (xxxvi) of Schedule A to
the Mortgage Loan Purchase and Sale Agreement, the Issuer's indemnity obligation
with respect thereto shall be without regard to the Indenture Trustee Expense
Limit.

                  (c) The Issuer's, the Depositor's and the Seller's payment
obligations to the Indenture Trustee pursuant to this Section shall survive the
discharge of this Indenture. Notwithstanding anything else set forth in this
Indenture or the Basic Documents, the Indenture Trustee agrees that the
obligations of the Issuer (but not the Depositor or the Seller) to the Indenture
Trustee hereunder and under the Basic Documents shall be recourse to the
Collateral only and shall not be recourse to any other assets of the Issuer or
any assets of any Noteholder. In addition, the Indenture Trustee agrees that its
recourse to the Collateral is subject to certain priorities and limitations as
specifically provided for in this Indenture.

                  SECTION 6.8. Replacement of Indenture Trustee. The Indenture
Trustee may resign at any time by so notifying the Issuer and the Insurer by
written notice. Upon receiving such notice of resignation, the Issuer shall
promptly appoint a successor Indenture Trustee (approved in writing by the
Insurer, so long as such approval is not unreasonably withheld) by written
instrument, in duplicate, one copy of such instrument shall be delivered to the
resigning Indenture Trustee (who shall deliver a copy to the Servicer, the
Depositor and the Insurer) and one copy to the successor Indenture Trustee;
provided, however, that any such successor Indenture Trustee shall be subject to
the prior written approval of the Depositor, which approval shall not be
unreasonably withheld, delayed or denied. The Issuer may, and at the request of
the Insurer shall, remove the Indenture Trustee, if:

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

                           (ii) a court having jurisdiction in the premises in
         respect of the Indenture Trustee in an involuntary case or proceeding
         under federal or state banking or bankruptcy laws, as now or hereafter
         constituted, or any other applicable federal or state bankruptcy,
         insolvency or other similar law, shall have entered a decree or order
         granting relief or appointing a receiver, liquidator, assignee,
         custodian, trustee, conservator, sequestrator (or similar official) for
         the Indenture Trustee or for any substantial part of the Indenture
         Trustee's property, or ordering the winding-up or liquidation of the
         Indenture Trustee's affairs;

                           (iii) an involuntary case under the federal
         bankruptcy laws, as now or hereafter in effect, or another present or
         future federal or state bankruptcy, insolvency or similar law is
         commenced with respect to the Indenture Trustee and such case is not
         dismissed within 60 days;

                           (iv) the Indenture Trustee commences a voluntary case
         under any federal or state banking or bankruptcy laws, as now or
         hereafter constituted, or any other applicable federal or state
         bankruptcy, insolvency or other similar law, or consents to the
         appointment of or taking possession by a receiver, liquidator,
         assignee, custodian, trustee, conservator, sequestrator (or other
         similar official) for the Indenture Trustee or for any substantial part
         of the Indenture Trustee's property, or makes any assignment for the

                                       30

<PAGE>

         benefit of creditors or fails generally to pay its debts as such debts
         become due or takes any corporate action in furtherance of any of the
         foregoing;

                           (v) the Indenture Trustee otherwise becomes incapable
         of acting; or

                           (vi) the Indenture Trustee materially breaches any
         covenant or obligation under the Basic Documents.

                  Additionally, the Issuer shall remove the Indenture Trustee at
the request of the Insurer.

                  If the Indenture Trustee resigns or is removed or if a vacancy
exists in the office of 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 acceptable to the
Insurer. If the Issuer fails to appoint such a successor Indenture Trustee
within 30 days, the Insurer may appoint a successor Indenture Trustee. If no
successor Indenture Trustee shall have been so appointed and have accepted
appointment within 45 days after the giving of such notice of resignation or
removal, the resigning or removed Indenture Trustee may petition any court of
competent jurisdiction for the appointment of a successor Indenture Trustee.

                  A successor Indenture Trustee shall deliver a written
acceptance of its appointment to the retiring Indenture Trustee, to the Insurer
and to the Issuer. Thereupon the resignation or removal of the retiring
Indenture Trustee shall become effective, and the successor Indenture Trustee
shall have all the rights, powers and duties of the retiring 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
30 days after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Issuer, the Insurer, or the Holders of a majority in
Outstanding Amount of the Notes may, at the expense of the Depositor, petition
any court of competent jurisdiction for the appointment of a successor Indenture
Trustee acceptable to the Insurer.

                  If the Indenture Trustee fails to comply with Section 6.11,
any Noteholder may petition any court of competent jurisdiction for the removal
of the Indenture Trustee and the appointment of a successor Indenture Trustee
acceptable to the Insurer.

                  Any resignation or removal of the Indenture Trustee and
appointment of a successor Indenture Trustee pursuant to any of the provisions
of this Section shall not become effective until acceptance of appointment by
the successor Indenture Trustee pursuant to Section 6.8 and payment of all fees
and expenses owed to the outgoing Indenture Trustee.

                  Notwithstanding the replacement of the Indenture Trustee
pursuant to this Section, the Issuer's, the Depositor's and the Seller's
indemnity obligations under Section 6.7 shall continue for the benefit of the
retiring Indenture Trustee and the Depositor shall pay any amounts owing to the
Indenture Trustee.

                  SECTION 6.9. 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 entity meets the requirements of Section 6.11 hereunder and
is otherwise acceptable to the Insurer (unless an Insurer Default has occurred
and is continuing). The Indenture Trustee shall provide the Insurer, the
Depositor and the Servicer with notice of any such transaction.

                  In case 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 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 in case 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 anywhere in the Notes or in this
Indenture.

                  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 may at the time be located, the Indenture
Trustee, with the consent of the Insurer, which consent shall not be
unreasonably withheld, delayed or denied, 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, and to vest in such Person or Persons, in such capacity
and for the benefit of the Noteholders, such title to the Trust, 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.

                  (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 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;

                                       32
<PAGE>

                           (ii) no trustee hereunder shall be personally liable
         by reason of any act or omission of any other trustee hereunder,
         including acts or omissions of predecessor or successor trustees; and

                           (iii) the Indenture Trustee and the Depositor acting
         jointly 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, dissolve, become insolvent, 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.

                  (e) The Depositor shall be responsible for the fees of any
co-trustee or separate trustee appointed hereunder.

                  (f) No separate trustee or co-trustee hereunder shall be
required to meet the terms of eligibility as an indenture trustee under Section
6.11 hereunder and no notice to the Noteholders shall be required under Section
11.05.

                  SECTION 6.11. Eligibility; Disqualification. The Indenture
Trustee shall at all times satisfy the requirements of TIA Section 310(a). The
Indenture Trustee shall have a combined capital and surplus of at least

connection herewith, except that the Indenture Trustee shall be liable for its
negligence, bad faith or willful misconduct; nor shall the Indenture Trustee be
responsible for the validity, effectiveness, value, sufficiency or
enforceability against the Issuer of this Indenture or any of the Collateral (or
any part thereof).

                  SECTION 6.16. Reliance Upon Documents. In the absence of
negligence, bad faith or willful misconduct on its part, the Indenture Trustee
shall be entitled to conclusively rely on any communication, instrument, paper
or other document reasonably believed by it to be genuine and correct and to

liability in acting, or omitting to act, where such action or omission to act is
in reasonable reliance upon any statement or opinion contained in any such
document or instrument.

Documents.

                  SECTION 6.18. Waiver of Setoff. The Indenture Trustee hereby

                  SECTION 6.19. Control by the Controlling Party. The Indenture

which such judgment has been recovered.

                  SECTION 6.21. Suits for Enforcement. In case an Event of
Servicing Termination or other default by the Servicer or the Depositor
hereunder shall occur and be continuing, the Controlling Party may proceed to
protect and enforce its rights and the rights of the Noteholders under this
Indenture by a suit, action or proceeding in equity or at law or otherwise,
whether for the specific performance of any covenant or agreement contained in
this Indenture or in aid of the execution of any power granted in this Indenture
or for the enforcement of any other legal, equitable or other remedy, as the
Indenture Trustee, being advised by counsel, shall deem most effectual to
protect and enforce any of the rights of the Indenture Trustee and the
Noteholders.

                  SECTION 6.22. Mortgagor Claims. In connection with any offset
defenses, or affirmative claim for recovery, asserted in legal actions brought

                  (a) The Indenture Trustee is the holder of the Mortgage Loans

Servicer, the Insurer, the Issuer, the Depositor, or holders of the Notes in
their defense of legal actions by Mortgagors to recover affirmative claims if
such cooperation and assistance is not contrary to the interests of the
Indenture Trustee as a party to such legal actions and if the Indenture Trustee
is satisfactorily indemnified for all liability, costs and expenses (including
attorneys' fees and expenses) arising therefrom.

                  (f) The Trust and the Seller (pursuant to the Sale and
Servicing Agreement) hereby agree to indemnify, hold harmless and defend the

of, and shall receive and collect, directly and without intervention or
assistance of any fiscal agent or other intermediary, all money and other

payment or performance under any agreement or instrument that is part of the
Collateral, the Indenture Trustee may, with the consent of the Insurer (so long
as no Insurer Default has occurred and is continuing, in which case, with the
consent of the majority of the Noteholders), or shall at the direction of the

                  (b) The Indenture Trustee shall, at such time as there are no
Notes outstanding and all sums due the Indenture Trustee pursuant to Section 6.7
or otherwise under this Indenture or the Basic Documents, and to the Insurer
pursuant to the Insurance Agreement have been paid and the Policy has been
cancelled and returned to the Insurer, release any remaining portion of the
Collateral that secured the Notes from the lien of this Indenture and release to
the Issuer or any other Person entitled thereto any funds then on deposit in the
Accounts. The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.2(b) only upon receipt by the Indenture

                  SECTION 8.3. Establishment of Distribution Account. The
Depositor shall cause to be established, and the Indenture Trustee shall
maintain, at the Corporate Trust Office of the Indenture Trustee, a Distribution
Account to be held by the Indenture Trustee in the name of the Issuer for the
benefit of the Indenture Trustee, the Noteholders and the Insurer, as their
interests may appear. Such account shall be an Eligible Account. The Indenture
Trustee shall hold funds in the Distribution Account uninvested or may invest
such funds in Eligible Investments selected by the Indenture Trustee, all in its
discretion. All income and gain realized from the Indenture Trustee's holding or
investment of the funds in the Distribution Account shall be for the benefit of
the Indenture Trustee and shall be subject to its withdrawal from time to time.
Any withdrawal of funds from the Distribution Account by the Indenture Trustee
shall be made for the following purposes:

                           (i) If not received by the Servicer pursuant to the
         Master Servicing Agreement, to the Servicer in payment of the Servicing
         Fee;

                           (ii) To withdraw and retain any earnings on or
         investment income with respect to funds in or credited to the
         Distribution Account;

                           (iii) To make or to permit the Indenture Trustee to
         make distributions and payments pursuant to Section 8.7 of the
         Indenture;

                           (iv) To pay to the Servicer any Liquidation Expenses
         not reimbursed prior to the deposit of Net Liquidation Proceeds to the
         Distribution Account; and

                           (v) Upon termination of the Trust, to make any
         payments required by Section 7.01.

                  If the Servicer deposits in the Distribution Account any
amount not required to be deposited therein or any amount in respect of payments
by Mortgagors made by checks subsequently returned for insufficient funds or
other reason for non payment, the Indenture Trustee shall, upon request of the
Servicer, immediately withdraw such amount from the Distribution Account, and
any such amounts shall not be included in the amounts to be deposited

                                       39

in the Distribution Account pursuant to this Agreement, any provision herein to
the contrary notwithstanding.

                  SECTION 8.4. The Policy.

                  (a) By the close of business on the Business Day preceding
each Determination Date the Indenture Trustee shall determine from the Servicing
Certificate with respect to the immediately following Payment Date, the
Deficiency Amount, if any.

                  (b) If the Indenture Trustee determines pursuant to paragraph
(a) above that a Deficiency Amount would exist, the Indenture Trustee shall
complete a Notice in the form of Exhibit A to the Policy and submit such notice
to the Insurer no later than 12:00 noon New York City time on the related
Determination Date preceding such Payment Date as a claim for the payment of an
Insured Amount in an amount equal to the Deficiency Amount.

                  (c) The Indenture Trustee shall establish an Eligible Account
(which may be a sub-account of the Distribution Account) for the benefit of the
Noteholders and the Insurer referred to herein as the "Policy Payment Account"
over which the Indenture Trustee shall have exclusive control and sole right of
withdrawal. The Indenture Trustee shall deposit upon receipt any amount paid
under the Policy into the Policy Payment Account and distribute such amount only
for purposes of payment to the Noteholders of the Insured Amount for which a
claim was made and such amount may not be applied to satisfy any costs, expenses
or liabilities of the Depositor, the Servicer, the Indenture Trustee or the
Trust. Amounts paid under the Policy, to the extent needed to pay the Insured
Amount, shall be disbursed by the Indenture Trustee to the Noteholders in
accordance with Section 8.7(b)(iv), (vi) and (vii), as applicable. It shall not
be necessary for such payments to be made by check or wire transfers separate
from checks or wire transfers used to pay the Insured Amount with other funds
available to make such payment. However, the amount of any payment of principal
or interest on the Notes to be paid from funds transferred from the Policy
Payment Account shall be noted as provided in subsection (d) of this Section 8.4
and in the Indenture Trustee's Statement to Noteholders. Funds held in the
Policy Payment Account shall not be invested. Any funds remaining in the Policy
Payment Account on the first Business Day following a Payment Date shall be
returned to the Insurer pursuant to the written instructions of the Insurer by
the end of such Business Day.

                  (d) The Indenture Trustee shall keep a complete and accurate
record of the amount of interest and principal paid in respect of any Note from
moneys received under the Policy. The Insurer shall have the right to inspect
such records at reasonable times during normal business hours upon one (1)
Business Day's prior written notice to the Indenture Trustee.

                  (e) The Indenture Trustee shall, upon retirement of the Notes,
furnish to the Insurer a notice of such retirement, and, upon retirement of the
Notes and the expiration of the term of the Policy, surrender the Policy to the
Insurer for cancellation.

the Insurer shall receive at least seven days' notice when requested by the

condition to such action, an Opinion of Counsel (addressed to the Indenture
Trustee and to the Insurer), stating the legal effect of any such action,

conditions precedent to the taking of such action have been complied with and
such action will not materially and adversely impair the security for the Notes
or the rights of the Noteholders or the Insurer in contravention of the
provisions of this Indenture; provided, however, that such Opinion of Counsel
shall not be required to express an opinion as to the fair value of the
Collateral. Counsel rendering any such opinion may rely, without independent
investigation, on the accuracy and validity of any certificate or other
instrument delivered to the Indenture Trustee in connection with any such
action.

shall not, as evidenced by an Opinion of Counsel, adversely affect in any
material respect the interests of any Noteholder.

                  SECTION 9.2. Supplemental Indentures with Consent of
Noteholders. The parties hereto, when authorized by an Issuer Order, also may,

that, subject to the express rights of the Insurer under the Basic Documents, no
such supplemental indenture shall, without the consent of the Holder of each
Outstanding Notes affected thereby:

                           (i) change the date of payment of any installment of

         thereof, the interest rate thereon or the Redemption Price with respect
         thereto, change the provision of this Indenture relating to the

         respective due dates thereof (or, in the case of redemption, on or
         after the Redemption Date);

                           (iii) reduce the percentage of the Outstanding Amount
         of the Notes, the consent of the Holders of which is required for any
         such supplemental indenture, or the consent of the Holders of which is
         required for any waiver of compliance with certain provisions of this
         Indenture or certain defaults hereunder and their consequences provided
         for in this Indenture;

         increase any percentage specified herein or to provide that certain

         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.

                  The Indenture Trustee may conclusively rely as to whether or
not any Notes would be adversely affected by any supplemental indenture upon
receipt of an Opinion of

                                       47
<PAGE>

Counsel addressed and delivered to the Indenture Trustee and the Insurer to that
effect and any such determination shall be conclusive upon the Holders of all
Notes, whether theretofore or thereafter authenticated and delivered hereunder.
The Indenture Trustee shall not be liable for relying on such Opinion of Counsel
in good faith.

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

supplemental indenture pursuant to this Section, 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 9.3. Execution of Supplemental Indentures. In
executing, or permitting the additional trusts created by, any supplemental
indenture permitted by this Article IX or the modifications thereby of the
trusts created by this Indenture, the Indenture Trustee and the Insurer shall be
entitled to receive, and subject to Sections 6.1 and 6.2, shall be fully
protected in relying upon, an Opinion of Counsel (and, if requested, an
Officer's Certificate) 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 9.4. Effect of Supplemental Indenture. Upon the
execution of any supplemental indenture pursuant to the provisions hereof, this
Indenture shall be and 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 9.5. Reference in Notes to 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 TIA as then in effect so long as this Indenture shall then be qualified
under the TIA.

                  SECTION 9.6. 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

                                       48
<PAGE>

prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Notes.

                                    ARTICLE X

                               Redemption of Notes

                  SECTION 10.1. Redemption; Repurchase. The Notes are subject to
redemption or repurchase in whole, but not in part, at the direction of the
applicable Optional Redemption Holder pursuant to Section 7.01(b) of the Sale
and Servicing Agreement, on any Payment Date on which such Optional Redemption
Holder exercises its option to transfer the Trust Property pursuant to said
Section 7.01(b) or to repurchase for a purchase price equal to the Redemption
Price the Notes without the transfer of the Trust Property. The Depositor or the
Issuer shall furnish the Insurer notice of such redemption or repurchase not
later than 35 days prior to the Redemption Date. If the Notes are to be redeemed
or repurchased pursuant to this Section 10.1, the Depositor or the Issuer shall
furnish notice of such election to the Indenture Trustee not later than 35 days
prior to the Redemption Date and the Issuer shall deposit or undertake to
deposit on or prior to the Redemption Date with the Indenture Trustee in the
Distribution Account the Redemption Price of such Notes whereupon all such Notes
shall be due and payable on the Redemption Date (or, in the case of a
repurchase, the Redemption Price shall be payable to the Holders thereof) upon
the furnishing of a notice complying with Section 10.2 (unless the Issuer shall
default in the deposit of the Redemption Price). If the Notes are redeemed by
the Optional Redemption Holder without the purchase of the Trust Property, the
Notes will remain Outstanding and will be registered to, or to the order of, the
Optional Redemption Holder in accordance with the terms of this Indenture.

                  SECTION 10.2. Surrender of Notes.

                  (a) Notice of any termination or other redemption, specifying
the Payment Date (which shall be a date that would otherwise be a Payment Date)
upon which the Noteholders may surrender their Notes to the Indenture Trustee
for payment of the final distribution and (if applicable) cancellation, shall be
given by the Indenture Trustee (upon receipt of written directions from the
Optional Redemption Holder, if the Optional Redemption Holder is exercising its
right to transfer the Mortgage Loans) promptly to the Insurer, the Servicer, the
Depositor and to the Noteholders in accordance with Section 10.03. In the event
written directions are delivered to the Indenture Trustee as described in
Section 10.01, the Optional Redemption Holder shall deposit in the Distribution
Account on or before the Payment Date for such final distribution in immediately
available funds an amount which, when added to the funds on deposit in the
Collection Account that are payable to the Noteholders, will be equal to the
Redemption Price, together with all amounts due and owing to the Indenture
Trustee under this Indenture and the Basic Documents and to the Insurer for
unpaid premiums and unreimbursed draws on the Policy and all other amounts due
and owing to the Insurer pursuant to the Insurance Agreement, together with
interest thereon as provided under the Insurance Agreement.

                  (b) Upon presentation and surrender of the Notes, the
Indenture Trustee shall cause to be distributed to the Holders of Notes on the
Payment Date for such final distribution, in proportion to the Percentage
Interests of their respective Notes and to the extent that funds are

                                       49
<PAGE>

available for such purpose, the amount required to be distributed to Noteholders
pursuant to Section 10.1 of this Indenture for such Payment Date. The
distribution on such final Payment Date pursuant to a redemption pursuant to
Section 7.01(a)(B)(i) of the Sale and Servicing Agreement shall be in lieu of
the distribution otherwise required to be made on such Payment Date in respect
of the Notes. On the final Payment Date prior to having made the distributions
called for above, the Indenture Trustee shall withdraw from the Distribution
Account and pay to reimburse itself for all amounts due and owing to the
Indenture Trustee under this Indenture and the Basic Documents and shall, based
upon the information set forth in the Servicing Certificate for such Payment
Date, withdraw from the Distribution Account and remit to the Insurer the lesser
of (x) the amount available for distribution on such final Payment Date and (y)
the unpaid amounts due and owing to the Insurer for unpaid premiums and
unreimbursed draws on the Policy and all other amounts due and owing to the
Insurer pursuant to the Insurance Agreement, together with interest thereon as
provided under the Insurance Agreement.

                  (c) In the event that all of the Noteholders shall not
surrender their Notes for final payment and (if applicable) cancellation on or
before such final Payment Date, the Indenture Trustee shall on such date cause
all funds in the Distribution Account not distributed in final distribution to
Noteholders to be withdrawn therefrom and credited to the remaining Noteholders
by depositing such funds in a separate escrow account for the benefit of such
Noteholders and the Optional Redemption Holder (if the Optional Redemption
Holder has exercised its right to transfer the Mortgage Loans) or the Indenture
Trustee (in any other case) and shall give a second written notice to the
remaining Noteholders to surrender their Notes for cancellation and receive the
final distribution with respect thereto. If within one year after the second
notice all the Notes shall not have been surrendered for cancellation, the
Indenture Trustee may take appropriate steps, or may appoint an agent to take
appropriate steps, to contact the remaining Noteholders concerning surrender of
their Notes, and the cost thereof shall be paid out of the funds on deposit in
such escrow account.

                  SECTION 10.3. Redemption Notice. Notice of redemption supplied
under Section 10.1 shall be given by the Indenture Trustee by facsimile or by
first-class mail, postage prepaid, transmitted or mailed at least 20 days prior
to the applicable Redemption Date to each Holder of Notes of record, as of the
Record Date for the last Payment Date preceding the applicable Redemption Date,
at such Holder's address appearing in the Note Register.

                  All notices of redemption shall state:

                           (i) the Redemption Date upon which final payment of
         the Notes will be made (if the Notes are being retired) and whether the
         Notes will remain Outstanding thereafter;

                           (ii) the amount of any distribution on the Redemption
         Date;

                           (iii) that the Record Date otherwise applicable to
         such Redemption Date is not applicable and that payments shall be made
         only upon presentation and surrender of such Notes at the place where
         such Notes are to be surrendered for payment of the Redemption Price
         (which shall be the office or agency of the Issuer to be maintained as
         provided in Section 3.2); and

                                       50
<PAGE>

                           (iv) that interest on the Notes shall cease to accrue
         on the Redemption Date.

                  Notice of redemption of the Notes shall be given by the
Indenture Trustee in the name and at the expense of the Issuer. Failure to give
notice of redemption, or any defect therein, to any Holder of any Note shall not
impair or affect the validity of the redemption of any other Note.

                  SECTION 10.4. Notes Payable on Redemption Date. The Notes to
be redeemed shall (unless such Notes will remain Outstanding as set forth
above), following notice of redemption as required by Section 10.2, on the
Redemption Date become due and payable at the Redemption Price (and, if such
Notes will remain Outstanding, the Redemption Price will be payable to the
then-current Holders of the Notes) and (unless the Issuer shall default in the
payment of the Redemption Price) no interest shall accrue on the Redemption
Price for any period after the date to which accrued interest is calculated for
purposes of calculating the Redemption Price.

                                   ARTICLE XI

                  SECTION 11.1. Compliance Certificates and Opinions, etc. Upon
any application or request by the Issuer to the Indenture Trustee to take any
action under any provision of this Indenture, the Issuer shall furnish to the
Indenture Trustee and to the Insurer if the application or request is made to
the Indenture Trustee (i) an Officer's Certificate stating that all conditions
precedent, if any, provided for in this Indenture relating to the proposed
action have been complied with, (ii) an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent, if any, have been
complied with and (iii) (if required by the TIA or any provision of this
Agreement) an Independent Certificate from a firm of certified public
accountants meeting the applicable requirements of this Section, except that, in
the case of any such application or request as to which the furnishing of such
documents is specifically required by any provision of this Indenture, no
additional certificate or opinion need be furnished.

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

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

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

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

                                       51
<PAGE>

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

                  SECTION 11.2. 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 or her 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 Servicer, the Depositor or the Issuer, stating that the information with
respect to such factual matters is in the possession of the Servicer, the
Depositor 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. Any certificate, Issuer Order or
Issuer Request may be executed on behalf of the Issuer by the Depositor.

                  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 conclusively
rely upon the truth and accuracy of any statement or opinion contained in any
such document as provided in Article VI.

                  SECTION 11.3. 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

                                       52
<PAGE>

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 6.1) conclusive in favor of
the Indenture Trustee and the Issuer, if made in the manner provided in this
Section.

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

                  (c) The ownership of Notes shall be proved by the Note
Register.

                  (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 11.4. Notices, etc., to Indenture Trustee, Issuer,
Insurer and Rating Agencies. Any request, demand, authorization, direction,
notice, order, instruction, consent, waiver or Act of Noteholders or other
documents provided or permitted by this Indenture to be made upon, given or
furnished to or filed with:

                  (a) The Indenture Trustee by any Noteholder or by the Issuer
shall be made in writing and either personally delivered, delivered by facsimile
by overnight courier or mailed first-class to the Indenture Trustee at Sixth

all other purposes at its Corporate Trust Office, or

                  (b) The Issuer by the Indenture Trustee or by any Noteholder
shall be sufficient for every purpose hereunder if personally delivered,
delivered by facsimile or overnight courier or mailed first class, and shall
deemed to have been duly given upon receipt to the Issuer addressed to: Sequoia
HELOC Trust 2004-1, in care of Wilmington Trust Company, Rodney Square North,
1100 North Market Street, Wilmington, Delaware 19890-1605, Telecopy: (302)
636-4140, Attention: Corporate Trust Administration, or at any other address
previously furnished in writing to the Indenture Trustee by Issuer. The Issuer
shall promptly transmit any notice received by it from the Noteholders to the
Indenture Trustee and the Indenture Trustee shall provide a copy of any notice
it receives from the Issuer or any Noteholder to the Owner Trustee for
distribution to the Class L Certificateholders.

                  (c) The Insurer by the Issuer or the Indenture Trustee shall
be sufficient for any purpose hereunder if in writing and mailed by first-class
mail personally delivered or telecopied to the recipient as follows:

                  To the Insurer:      Ambac Assurance Corporation
                                       One State Street Plaza

                                       New York, NY 10004
                                       Attention: Managing Director

                                       Telecopy: (212) 363-1459

                  Notices required to be given to the Rating Agencies by the
Issuer, the Indenture Trustee or the Owner Trustee shall be in writing,
personally delivered, delivered by overnight courier or first class or via
facsimile to (i) in the case of Moody's, at the following address: Moody's
Investors Service, Inc., 99 Church Street, New York, New York 10004, Fax No:
(212) 533-0355 and (ii) in the case of S&P, at the following address: Standard &
Poor's, a division of The McGraw-Hill Companies, Inc., 55 Water Street, New
York, New York 10041, Attention: Asset Backed Surveillance Department, Fax No:
(212) 438-2661; or as to each of the foregoing, at such other address as shall
be designated by written notice to the other parties.

                  SECTION 11.5. 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 (and in all cases, the Insurer shall receive notice), at his 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.

                  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.

                  SECTION 11.6. Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Notes to the
contrary, the Issuer may enter into any agreement with any Holder of a Note
providing for a method of payment, or notice by the Indenture Trustee or any
Note Paying Agent to such Holder, that is different from the methods provided
for in this Indenture for such payments or notices, provided that such methods
are reasonable and consented to by the Indenture Trustee (which consent shall
not be unreasonably withheld). The Issuer will furnish to the Indenture Trustee
a copy of each such agreement and the

                                       54
<PAGE>

Indenture Trustee will cause payments to be made and notices to be given in
accordance with such agreements.

                  SECTION 11.7. 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 TIA, such required provision shall control.

                  The provisions of TIA Sections 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 11.8. Effect of Headings and Table of Contents. The
Article and Section headings herein and the Table of Contents are for
convenience only and shall not affect the construction hereof.

                  Notwithstanding anything to the contrary contained in this
Indenture or any document delivered herewith, all persons may disclose to any
and all persons, without limitation of any kind, the federal income tax
treatment of the Notes, any fact relevant to understanding the federal tax
treatment of the Notes, and all materials of any kind (including opinions or
other tax analyses) relating to such federal tax treatment.

                  SECTION 11.9. 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.

                  SECTION 11.10. Severability. 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 11.11. Benefits of Indenture. The Insurer and its
successors and assigns shall be third-party beneficiaries to the provisions of
this Indenture, and shall be entitled to rely upon and directly to enforce such
provisions of this Indenture. Nothing in this Indenture or in the Notes, express
or implied, shall give to any Person, other than the parties hereto and their
successors hereunder, the Insurer, and the Noteholders, and any other party
secured hereunder, and any other person with an ownership interest in any part
of the Collateral, any benefit or any legal or equitable right, remedy or claim
under this Indenture. The Insurer may disclaim any of its rights and powers
under this Indenture (in which case the Indenture Trustee may exercise such
rights or powers hereunder), but not its duties and obligations under the Policy
upon delivery of a written notice to the Indenture Trustee.

                  SECTION 11.12. 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.

                                       55

                  SECTION 11.13. GOVERNING LAW. THIS INDENTURE SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT
REFERENCE TO ITS CONFLICT OF LAW PROVISIONS (OTHER THAN SECTIONS 5-1401 AND
5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW), AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH
LAWS.

                  SECTION 11.14. 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 11.15. 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 (which may be counsel to the Issuer or any other counsel reasonably
acceptable to the Indenture Trustee and the Insurer) 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 11.16. Trust Obligation. No recourse may be taken,
directly or indirectly, with respect to the obligations of the Issuer, the
Depositor, the Servicer, the Owner Trustee or the Indenture Trustee on the Notes
or under this Indenture or any Note or other writing delivered in connection
herewith or therewith, against (i) the Depositor, the Servicer, 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, shareholder, employee or agent of the Depositor, the
Servicer, the Indenture Trustee or the Owner Trustee in its individual capacity,
any holder of a beneficial interest in the Issuer, the Depositor, the Servicer,
the Owner Trustee or the Indenture Trustee or of any successor or assign of the
Depositor, the Servicer, the Indenture Trustee or the Owner Trustee in its
individual capacity, except as any such Person may have expressly agreed (it
being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such 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 Articles VI, VII and VIII of the Trust
Agreement.

                  SECTION 11.17. 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 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.

                                       56
<PAGE>

                  SECTION 11.18. Inspection. The Issuer agrees that, on
reasonable prior notice, it will permit any representative of the Indenture
Trustee or of the Insurer, during the Issuer's normal business hours, to examine
all the books of account, records, reports, and other papers of the Issuer, to
make copies and extracts therefrom, to cause such books to be audited by
independent certified public accountants, and to discuss the Issuer's affairs,
finances and accounts with the Issuer's officers, employees, and independent
certified public accountants, all at such reasonable times and as often as may
be reasonably requested. The Indenture Trustee shall and 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.

                  SECTION 11.19. Limitation of Liability. It is expressly
understood and agreed by the parties hereto that (a) this Indenture is executed
and delivered by Wilmington Trust Company, not individually or personally but
solely as Owner Trustee of the Issuer under the Trust Agreement, in the exercise
of the powers and authority conferred and vested in it, (b) each of the
representations, undertakings and agreements herein made on the part of the
Issuer is made and intended not as personal representations, undertakings and
agreements by Wilmington Trust Company but is made and intended for the purpose
for binding only the Issuer, (c) nothing herein contained shall be construed as
creating any liability on Wilmington Trust Company individually or personally,
to perform any covenant either expressed or implied contained herein, all such
liability, if any, being expressly waived by the parties to this Indenture and
by any person claiming by, through or under them and (d) under no circumstances
shall Wilmington Trust Company be personally liable for the payment of any
indebtedness or expenses of the Issuer or be liable for the breach or failure of
any obligation, representation, warranty or covenant made or undertaking by the
Issuer under this Indenture or any related documents.

                                   ARTICLE XII

                  Rapid Amortization Events; Events of Default

                  SECTION 12.1. Rapid Amortization Events. The following shall
constitute Rapid Amortization Events with respect to the Notes:

                  (a) failure on the part of the Seller, the Depositor or the
Servicer, as the case may be, (i) to make any payment or deposit required by the
terms of this Indenture, the Sale and Servicing Agreement or the Insurance
Agreement, as applicable, within five Business Days after notification that such
payment or deposit is required to be made, or (ii) to observe or perform in any
material respect the covenants or agreements of the Seller, the Depositor or the
Servicer, as the case may be, set forth in the Sale and Servicing Agreement or
the Insurance Agreement or this Indenture, as the case may be, and which, in the
case of clause (ii), continues unremedied for a period of 60 days after the date
on which written notice of such failure, requiring the same to be remedied,
shall have been given to the Seller, the Depositor or the Servicer, as the case
may be, by the Indenture Trustee, or to the Seller, the Depositor or the
Servicer, as the case may be, and the Indenture Trustee by the Insurer;

                                       57
<PAGE>

                  (b) any representation or warranty made by the Seller, the
Depositor or the Servicer, as the case may be, in this Indenture, the Sale and
Servicing Agreement or the Insurance Agreement shall prove to have been
incorrect in any material respect when made, as a result of which the interests
of the Noteholders or the Insurer are materially and adversely affected and
which continues to be incorrect in any material respect and continues to affect
materially and adversely the interests of the Noteholders or the Insurer for a
period of 60 days after the date on which written notice of such failure,
requiring the same to be remedied, shall have been given to the Depositor, the
Seller or the Servicer, as the case may be, by the Indenture Trustee, or to the
Depositor, the Seller or the Servicer, as the case may be, and the Indenture
Trustee by the Insurer; provided, however, that with respect to any such
representation or warranty made with respect to any Mortgage Loan, a Rapid
Amortization Event shall not be deemed to occur if the Seller has purchased such
Home Equity Loan within 90 days (or within an additional 30 days with the
consent of the Indenture Trustee and the Insurer).

                  (c) the Seller or the Depositor or any of their Subsidiaries
or Affiliates shall voluntarily go into liquidation, consent to the appointment
of a conservator or receiver or liquidator or similar person in any insolvency,
readjustment of debt, marshalling of assets and liabilities or similar
proceedings of or relating to the Seller or the Depositor or of or relating to
all or substantially all of such Person's property, or a decree or order of a
court or agency or supervisory authority having jurisdiction in the premises for
the appointment of a conservator, receiver, liquidator or similar person in any
insolvency, readjustment of debt, marshalling of assets and liabilities or
similar proceedings, or for the winding-up or liquidation of its affairs, shall
have been entered against the Seller or the Depositor and such decree or order
shall have remained in force undischarged or unstayed for a period of 30 days;
or the Seller or the Depositor shall admit in writing its inability to pay its
debts generally as they become due, file a petition to take advantage of any
applicable insolvency or reorganization statute, make an assignment for the
benefit of its creditors or voluntarily suspend payment of its obligations;

                  (d) the Issuer becomes subject to regulation by the Securities
and Exchange Commission as an investment company within the meaning of the
Investment Company Act of 1940, as amended;

                  (e) any draw is made under the Policy in respect of principal
of the Notes;

                  (f) an Event of Servicing Termination has occurred;

                  (g) the Issuer is determined to be an association taxable as a
corporation that does not constitute a "qualified REIT subsidiary" under the
Code for federal income tax purposes; or

                  (h) an Event of Default has occurred.

                  In the case of any event described in clauses (a) through (h)
above, a Rapid Amortization Event will be deemed to have occurred only if, after
the applicable grace period, if any, described in the Indenture or Sale and
Servicing Agreement, any of the Indenture Trustee or Holders holding Notes
evidencing more than 50% of the Outstanding Amount, in each case with the prior
written consent of the Insurer (so long as no Insurer Default has occurred and
is
                                       58
<PAGE>

continuing) or the Insurer (so long as no Insurer Default has occurred and is
continuing), by written notice to the Issuer, the Insurer, the Depositor, and
the Servicer (and to the Indenture Trustee, if given by the Noteholders or the
Insurer) declare that a Rapid Amortization Event has occurred as of the date of
such notice.

                  In addition to the consequences of a Rapid Amortization Event
discussed above, if the Depositor voluntarily files a bankruptcy petition or
goes into liquidation or any person is appointed a receiver or bankruptcy
trustee of the Depositor, on the day of any such filing or appointment no
further Additional Balances will be transferred to the Trust and the Depositor
will promptly give notice to the Indenture Trustee and the Insurer of any such
filing or appointment. Within 15 days, the Indenture Trustee notify the Holders
of the Notes of the occurrence of such event.

                  SECTION 12.2. Certain Consequences of an Event of Default.
Following the occurrence of an Event of Default, if so directed by the Insurer,
so long as no Insurer Default has occurred and is continuing (or, if an Insurer
Default has occurred and is continuing, if so directed by Holders holding Notes
evidencing more than 50% of the Outstanding Amount), the Indenture Trustee will
sell, dispose of or otherwise liquidate the Collateral with respect to the
Mortgage Loans in a commercially reasonable manner and on commercially
reasonable terms. So long as (i) no Event of Servicing Termination has occurred
and is continuing and (ii) such Event of Default was not caused by the Servicer,
any such sale, disposal or liquidation will be "servicing retained" by the
Servicer. With respect to the Notes, the net proceeds of such sale will be paid
(i) first, to the Indenture Trustee and the Owner Trustee, any unpaid fees due
and owing and to the Indenture Trustee, any unpaid expenses due and owing
(subject to the Indenture Trustee Expense Limit), (ii) second, to the Holders of
the Notes, insofar as may be necessary to reduce the Note Principal Balance of
the Notes, together with all accrued and unpaid interest due thereon, to zero,
(iii) third, to reimburse the Insurer to the extent of unreimbursed draws under
the Policy and other amounts owing to the Insurer, (iv) fourth, to the Indenture
Trustee and the Owner Trustee, any unreimbursed expenses due and owing,
including, with respect to the Indenture Trustee, all unreimbursed expenses
incurred by the Indenture Trustee in connection with such Event of Default and
sale of the Collateral and (v) fifth, to the Residual Certificateholders, in the
order and priority described in Section 8.7(b)(xiv), any remaining amounts.

                     HELOC ASSET-BACKED NOTES, SERIES 2004-1

                  Sequoia HELOC Trust 2004-1, a statutory trust organized and
existing under the laws of the State of Delaware (herein referred to as the
"Issuer"), for value received, hereby promises to pay to CEDE & CO., or
registered assigns, the principal sum of [_______________________]
($[___________]), such amount payable on each Payment Date in an amount equal to
the result obtained by multiplying (i) a fraction the numerator of which is
$[_________] and the denominator of which is $[_________] by (ii) the aggregate
amount, if any, payable from the Distribution Account in respect of principal on
the Notes pursuant to Section 8.7 of the Indenture; provided, however, that the
entire unpaid principal amount of this Note and all accrued and unpaid interest
shall be due and payable on the Payment Date in [_____] (the "Final Scheduled
Payment Date"). The Issuer will pay accrued interest on this Note on each
Payment Date in accordance with the priority of payments set forth in the
Indenture. Interest on this Note will accrue for each Payment Date at the Note
Rate on the Outstanding Amount hereof from the most recent Payment Date on which
interest has been paid to but excluding such Payment Date or, if no interest has
yet been paid, from the Closing Date. Interest will be computed on the basis of
the actual number of days elapsed in a 360-day year. Such principal of and
interest on this Note shall be paid in the manner specified on the reverse
hereof.

                  The principal of and interest on this Note are payable 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 applied first to interest due and
payable on this Note as provided above and then to the unpaid principal of this
Note.

                  The Notes are entitled to the benefits of a certificate
guaranty insurance policy (the "Policy") issued by Ambac Assurance Corporation
(the "Insurer"), pursuant to which the Insurer has unconditionally guaranteed
payments of the Insured Amounts with respect to the Notes on each Payment Date
and Preference Amounts, all as more fully set forth in the Policy.

                  For purposes of federal income, state and local income and
franchise and any other income taxes, the Issuer will treat the Notes as
indebtedness of the Issuer and the Residual Certificates as equity in the Issuer
and has instructed the Indenture Trustee to prepare tax returns and reports
regarding the Notes and the Trust consistent with such treatment for federal and
state tax reporting purposes. Each Noteholder by acceptance of a Note (and each
owner of a beneficial interest in a Note by acceptance of such beneficial
interest) agrees to treat the Notes for federal income, state and local income
and franchise and any other income taxes as indebtedness of the Issuer.

                  Each Noteholder or Note Owner, by acceptance of this Note or,
in the case of a Note Owner, a beneficial interest in a Note, covenants and
agrees that 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 the Indenture or any certificate or other writing delivered in
connection therewith, against (i) the Depositor, the Seller, the Servicer, the

                                      A-1-2

<PAGE>

Indenture Trustee, or the Owner Trustee in its individual capacity, (ii) any
owner of a beneficial interest in the Issuer or (iii) any owner, beneficiary,
agent, officer, director, shareholder or employee of the Depositor, the Seller,
the Servicer, the Indenture Trustee, or the Owner Trustee in its individual
capacity, any holder of a beneficial interest in the Issuer, the Depositor, the
Seller, the Servicer, the Owner Trustee or the Indenture Trustee or of any
successor or assign of the Depositor, the Seller, the Servicer, the Indenture
Trustee, or the Owner Trustee in its individual capacity, except as any such
Person may have expressly agreed (it being understood that the Indenture Trustee
and the Owner Trustee have no such obligations in their individual capacity) and
except that any such 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.

                  Reference is made to the further provisions of this Note set
forth on the reverse hereof, which shall have the same effect as though fully
set forth on the face of this Note.

                  Unless the certificate of authentication hereon has been
executed by the Indenture Trustee whose name appears below by manual signature,
this Note shall not be entitled to any benefit under the Indenture referred to
on the reverse hereof, or be valid or obligatory for any purpose.

                  This Note is one of a duly authorized issue of Notes of the
Issuer, designated as its HELOC Asset-Backed Notes, Series 2004-1 issued under
an Indenture dated as of June 1, 2004 (such agreement, as supplemented or
amended, is herein called the "Indenture"), between the Issuer and Wells Fargo
Bank, N.A., as Indenture Trustee (the "Indenture Trustee"), which term includes
any successor Indenture Trustee under the Indenture.

                  All terms used in this Note that are defined in the Indenture,
as supplemented or amended, shall have the meanings assigned to them in or
pursuant to the Indenture, as so supplemented or amended. If any such terms are
not defined in the Indenture, as supplemented or amended, then such terms shall
have the meanings assigned to them in or pursuant to the Trust Agreement dated
as of June 1, 2004 (such trust agreement, as supplemented or amended is herein
called the "Trust Agreement"), between Sequoia Mortgage Funding Corporation, as
Depositor, and Wilmington Trust Company, as Owner Trustee (the "Owner Trustee,"
which term includes any successor Owner Trustee under the Trust Agreement), as
so supplemented or amended.

                  The Notes are and will be secured by the collateral pledged as
security therefor as provided in the Indenture.

                  Principal of the Notes will be payable on each Payment Date in
an amount described in the Indenture. "Payment Date" means the twentieth (20th)
day of each month, or, if any such date is not a Business Day, the next
succeeding Business Day, commencing in July 2004. The term "Payment Date," shall
be deemed to include the Final Scheduled Payment Date.

                  As described above, the entire unpaid principal amount of this
Note shall be due and payable on the earlier of the Final Scheduled Payment Date
and the Redemption Date, if any, pursuant to Section 10.1 of the Indenture.
Notwithstanding the foregoing, on the date on which an Event of Default shall
have occurred and be continuing, the Insurer (so long as there is no

                                      A-1-3

<PAGE>

continuing Insurer Default) or, if an Insurer Default has occurred and is
continuing, Holders holding Notes evidencing more than 50% of the Outstanding
Amount, shall have the right among others to direct the Indenture Trustee to
sell or liquidate the Mortgage Loans as provided in Section 12.2 of the
Indenture and pay such amounts to the Holders of the Notes. All principal
payments on the Notes shall be made pro rata to the Holders of the Notes
entitled thereto.

                  Payments of accrued interest on this Note due and payable on
each Payment Date, together with the installment of principal, if any, to the
extent not in full payment of this Note, shall be made by wire transfer (or upon
the request of a Holder holding Notes having denominations aggregating at least
$1,000,000 and received by the Indenture Trustee at least five Business Days
prior to the related Record Date, by check or money order or otherwise) to the
Person whose name appears as the Holder of this Note (or one or more Predecessor
Notes) on the Note Register as of the close of business on each Record Date,
except that with respect to Note registered on the Record Date in the name of
the nominee of the Clearing Agency (initially, such nominee to be Cede & Co.),
payments will be made by wire transfer in immediately available funds to the
account designated by such nominee. Any check or money order shall be mailed to
the Person entitled thereto at the address of such Person as it appears on the
Note Register as of the applicable Record Date without requiring that this Note
be submitted for notation of payment. Any reduction in the principal amount of
this Note (or any one or more Predecessor Notes) effected by any payments made
on any Payment Date shall be binding upon all future Holders of this Note and of
any Note issued upon the registration of transfer hereof or in exchange hereof
or in lieu hereof, whether or not noted hereon. If funds are expected to be
available, as provided in the Indenture, for payment in full of the then
remaining unpaid principal amount of this Note on a Payment Date, then the
Indenture Trustee, in the name of and on behalf of the Issuer, will notify the
Person who was the Holder hereof as of the Record Date preceding such Payment
Date by notice mailed prior to such Payment Date and the amount then due and
payable shall be payable only upon presentation and surrender of this Note at
the office designated by the Indenture Trustee for such purposes.

                  The Issuer shall pay interest on overdue installments of
interest at the Note Rate to the extent lawful.

                  As provided in the Indenture, the Notes may be redeemed
pursuant to Section 10.1 of the Indenture, in whole, but not in part, at the
option of the holder of the Class C Interest or the holder of the majority
interest in the Class O Certificates (with the consent of the Insurer under
certain circumstances), on any Payment Date occurring after the end of a
Collection Period on which the Note Balance on such Payment Date is less than or
equal to 20% or 10%, respectively, of the Original Note Balance. In the case of
a redemption at the option of the holder of the Class C Interest, such holder
may elect to keep the Notes Outstanding following repurchase from the
then-current Holder.

                  As provided in the Indenture and subject to certain
limitations set forth therein, the transfer of this Note may be registered on
the Note Register upon surrender of this Note for registration of transfer at
the office or agency designated by the Issuer pursuant to the Indenture, (i)
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Indenture Trustee duly executed by, the Holder hereof or his
attorney duly authorized in writing, with such signature guaranteed by an
"eligible guarantor institution" meeting the

                                      A-1-4

<PAGE>

requirements of the Note Registrar which requirements include membership or
participation in Notes Transfer Agents Medallion Program ("Stamp") or such other
"signature guarantee program" as may be determined by the Registrar in addition
to, or in substitution for, Stamp, all in accordance with the Exchange Act, and
(ii) accompanied by such other documents as the Indenture Trustee may require,
and thereupon one or more new Notes of authorized denominations and in the same
aggregate principal amount will be issued to the designated transferee or
transferees. No service charge will be charged for any registration of transfer
or exchange of this Note, but the transferor may be required to pay a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection with any such registration of transfer or exchange.

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note covenants and agrees
that 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 the Indenture or any certificate or other writing delivered in
connection therewith, against (i) the Depositor, the Seller, the Servicer, the
Indenture Trustee or the Owner Trustee in its individual capacity, (ii) any
owner of a beneficial interest in the Issuer or (iii) any owner, beneficiary,
agent, officer, director, shareholder or employee of the Depositor, the Seller,
the Servicer, the Indenture Trustee or the Owner Trustee in its individual
capacity, any holder of a beneficial interest in the Issuer, the Depositor, the
Seller, the Servicer, the Owner Trustee or the Indenture Trustee or of any
successor or assign of the Depositor, the Seller, the Servicer, the Indenture
Trustee or the Owner Trustee in its individual capacity, except as any such
Person may have expressly agreed (it being understood that the Indenture Trustee
and the Owner Trustee have no such obligations in their individual capacity) and
except that any such 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.

                  Each Noteholder or Note Owner, by acceptance of a Note or, in
the case of a Note Owner, a beneficial interest in a Note covenants and agrees
that by accepting the benefits of the Indenture and the Trust Agreement that
such Noteholder will not at any time 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, the Trust
Agreement, the Indenture or the Basic Documents.

                  Prior to the due presentment for registration of transfer of
this Note, the Issuer, the Indenture Trustee and the Insurer and any agent of
the Issuer, the Indenture Trustee or the Insurer shall treat the Person in whose
name this Note (as of the day of determination or as of such other date as may
be specified in the Indenture) is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Issuer, the
Indenture Trustee nor any such agent 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 Note under the
Indenture at any time by the Issuer with the consent of the

                                      A-1-5

<PAGE>

Insurer and of the Holders of Notes representing a majority of the Outstanding
Amount of all Notes at the time Outstanding. Any such consent or waiver by the
Holder of this Note (or any one of more Predecessor Notes) shall be conclusive
and binding upon such Holder and upon all future Holders of this Note and of any
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 this
Note. The Indenture also permits the Indenture Trustee to amend or waive certain
terms and conditions set forth in the Indenture without the consent of Holders
of the Notes issued thereunder but with the consent of the Insurer.

                  The term "Issuer" as used in this Note includes any successor
to the Issuer under the Indenture or the Trust Agreement.

                  The Notes are issuable only in registered form in
denominations as provided in the Indenture, subject to certain limitations
therein set forth.

                  This Note and the 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
and thereunder shall be determined in accordance with such laws. The Trust
Agreement shall be construed in accordance with the laws of the State of
Delaware, without reference to its conflict of law provisions, and the
obligations, rights and remedies of the parties hereunder and thereunder shall
be determined in accordance with such laws.

                  No reference herein to the Trust Agreement or the Indenture
and no provision of this Note, the Trust Agreement or of the Indenture shall
alter or impair the obligation of the Issuer, which is absolute and
unconditional, to pay the principal of and interest on this Note at the times,
place, and rate, and in the coin or currency herein prescribed.

                  Anything herein to the contrary notwithstanding, except as
expressly provided in the Trust Agreement, the Indenture or the Basic Documents,
neither Wilmington Trust Company in its individual capacity, any owner of a
beneficial interest in the Issuer, nor any of their respective beneficiaries,
agents, officers, directors, shareholders, employees or successors or assigns
shall be personally liable for, nor shall recourse be had to any of them for,
the payment of principal of or interest on, or performance of, or omission to
perform, any of the covenants, obligations or indemnifications contained in this
Note or the Indenture, it being expressly understood that said covenants,
obligations and indemnifications have been made by the Issuer for the sole
purposes of binding the interests of the Issuer in the assets of the Issuer. The
Holder of this Note by the acceptance hereof agrees that except as expressly
provided in the Indenture or the Basic Documents in the case of a Rapid
Amortization Event or an Event of Default with respect to the Notes under the
Indenture, the Holder shall have no claim against any of the foregoing for any
deficiency, loss or claim therefrom; provided, however, that nothing contained
herein shall be taken to prevent recourse to, and enforcement against, the
assets of the Issuer for any and all liabilities, obligations and undertakings
contained in the Indenture or in this Note.
