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

            "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

or consent, only Bonds or Residual Certificates which the Owner Trustee or the
Indenture Trustee, respectively, 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

                                    The Bonds

            SECTION 2.1. Form. The Class A Bonds, together with the Indenture
Trustee's certificate of authentication, shall be in substantially the form set
forth in Exhibit A hereto, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture and may have such letters, numbers or other marks of identification
and such legends or endorsements placed thereon as may, consistently herewith,
be determined by the officers executing such Bonds, as evidenced by their
execution of the Bonds. Any portion of the text of any Bonds may be set forth on
the reverse thereof, with an appropriate reference thereto on the face of the
Bond.

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

            SECTION 2.2. Execution, Authentication and Delivery. The Bonds shall
be executed on behalf of the Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Bonds may be original or
facsimile.

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

            The Indenture Trustee shall authenticate and deliver Class A Bonds
for original issue in the aggregate principal amount of $_____________. The
Class A Bonds outstanding at any time may not exceed such amounts.

            Each Bond shall be dated the date of its authentication. The Bonds
shall be issuable as registered Bonds in the minimum denomination of $1,000 and
in integral multiples of $1,000 in excess thereof.

            No Bond shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears attached to such Bond
a certificate of authentication substantially in the form provided for herein
executed by the Indenture Trustee by the manual signature of one of its
authorized signatories, and such certificate attached to any Bonds shall be
conclusive evidence, and the only evidence, that such Bonds have been duly
authenticated and delivered hereunder. Subject to Section 2.11, the Bonds shall
be Book Entry Bonds.

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

                                       4
<PAGE>

            If a Person other than the Indenture Trustee is appointed by the
Issuer as Bond Registrar, the Issuer will give the Indenture Trustee and the
Insurer prompt written notice of the appointment of such Bond Registrar and of
the location, and any change in the location, of the Bond Register, and the
Indenture Trustee and the Insurer shall have the right to inspect the Bond
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 Bond Registrar by an Authorized Officer thereof as to the names and
addresses of the Holders of the Bonds and the principal amounts and number of
such Bonds.

            Upon surrender for registration or transfer of any Bond 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 or cause the Indenture Trustee to authenticate one or more new Bonds, in
any authorized denominations, of the same class and a like aggregate principal
amount. A Bondholder may also obtain from the Indenture Trustee, in the name of
the designated transferee or transferees one or more new Bonds, in any
authorized denominations, of the same class and a 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, Bonds may be exchanged for other Bonds
in any authorized denominations, of the same class and a like aggregate
principal amount, upon surrender of the Bonds to be exchanged at such office or
agency. Whenever any Bonds 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 Bonds which
the Bondholder 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 Bonds issued upon any registration of transfer or exchange of
Bonds shall be the valid obligations of the Issuer, evidencing the same debt,
and entitled to the same benefits under this Indenture, as the Bonds surrendered
upon such registration of transfer or exchange.

            Every Bond 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 Bond Registrar all in accordance with the Exchange Act, and
(ii) accompanied by such other documents as the Bond Registrar may require.

            No service charge shall be made to a Holder for any registration of
transfer or exchange of Bonds, but the Bond Registrar may require payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection with any registration of transfer or exchange of Bonds, other than
exchanges pursuant to Section 2.4 or 9.6 not involving any transfer.

            The Bond Registrar shall not register the transfer of a Definitive
Bond unless the Indenture Trustee has received a representation letter (in form
and substance satisfactory to the

                                       5
<PAGE>

Indenture Trustee) from the prospective transferee to the effect that either (a)
such transferee is not an employee benefit plan (as defined in Section 3(3) of
ERISA) that is subject to the provisions of Title I of ERISA or a plan (as
defined in Section 4975(e)(1) of the Code) that is subject to Section 4975 of
the Code (each, a "Benefit Plan") and is not acting on behalf of or investing
the assets of a Benefit Plan or (b) the acquisition and continued holding of
such Bond by the transferee will be covered by a U.S. Department of Labor
prohibited transaction class exemption. Each Bond Owner, by acceptance of a
beneficial interest in a Book-Entry Bond, will be deemed to make one of the
foregoing representations.

            SECTION 2.4. Mutilated, Destroyed, Lost or Stolen Bonds. If (i) any
mutilated Bond is surrendered to the Bond Registrar, or the Bond Registrar
receives evidence to its satisfaction of the destruction, loss or theft of any
Bond, and (ii) there is delivered to the Indenture Trustee and the Insurer such
security or indemnity as may be required by it to hold the Issuer, the Indenture
Trustee and the Insurer harmless, then, in the absence of notice to the Issuer,
the Bond Registrar or the Indenture Trustee that such Bond has been acquired by
a bona fide purchaser, and provided that the requirements of Section 8-405 of
the UCC are met, the Issuer shall execute and upon its request the Indenture
Trustee shall authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Bond, a replacement Bond (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 Bond, but not a mutilated Bond, 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 Bond, direct the
Indenture Trustee, in writing, to pay such destroyed, lost or stolen Bond when
so due or payable or upon the Redemption Date without surrender thereof. If,
after the delivery of such replacement Bond or payment of a destroyed, lost or
stolen Bond pursuant to the proviso to the preceding sentence, a bona fide
purchaser of the original Bond in lieu of which such replacement Bond was issued
presents for payment such original Bond, the Issuer, the Indenture Trustee and
the Insurer shall be entitled to recover such replacement Bond (or such payment)
from the Person to whom it was delivered or any Person taking such replacement
Bond from such Person to whom such replacement Bond was delivered or any
assignee of such Person, except a bona fide purchaser, and shall be entitled to
recover upon the security or indemnity provided therefor to the extent of any
loss, damage, cost or expense incurred by the Issuer, the Indenture Trustee or
the Insurer in connection therewith.

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

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

                                       6
<PAGE>

            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 Bonds.

            SECTION 2.5. Persons Deemed Owners. Prior to due presentment for
registration of transfer of any Bond, the Issuer, the Indenture Trustee and the
Insurer and any agent of the Issuer, the Indenture Trustee and the Insurer may
treat the Person in whose name any Bond is registered (as of the Record Date) as
the owner of such Bond for the purpose of receiving payments of principal of and
interest, if any, on such Bond and for all other purposes whatsoever, whether or
not such Bond be overdue, and none of the Issuer, the Insurer, the Indenture
Trustee nor any agent of the Issuer, the Insurer or the Indenture Trustee shall
be affected by notice to the contrary.

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

            (a)   The Bonds 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 Bond 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 Bond (or one or more
Predecessor Bonds) is registered on the Record Date, by check mailed
first-class, postage prepaid, to such Person's address as it appears on the Bond
Register on such Record Date, except that, unless Definitive Bonds have been
issued pursuant to Section 2.11, with respect to Bonds registered on the Record
Date in the name of the nominee of the Clearing Agency (initially, such nominee
to be Cede & Co.), payment will be made by wire transfer in immediately
available funds to the account designated by such nominee and except for the
final installment of principal payable with respect to such Bond on a Payment
Date or on the Final Scheduled Payment Date (and except for the Redemption Price
for any Bond called for redemption pursuant to Section 10.1) which shall be
payable as provided below. 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 Bond 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 Bond
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 Bond and shall specify the
place where such Bond may be presented and surrendered for payment of such
installment. Notices in connection with redemptions of Bonds shall be mailed to
Bondholders as provided in Section 10.2.

            (c)   If the Issuer defaults in a payment of interest on the Bonds,
the Issuer shall pay defaulted interest (plus interest on such defaulted
interest to the extent lawful) at the applicable Bond Rate to the extent lawful.
The Issuer may pay such defaulted interest to the Persons who are Bondholders 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 Bondholder, 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.

                                       7
<PAGE>

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

            SECTION 2.7. Cancellation. Subject to Section 2.6(d), all Bonds
surrendered for payment, registration of transfer, exchange or redemption shall,
if surrendered to any Person other than the Indenture Trustee, be delivered to
the Indenture Trustee and shall be promptly 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 Bonds previously authenticated and delivered
hereunder which the Issuer may have acquired in any manner whatsoever, and all
Bonds so delivered shall be promptly canceled by the Indenture Trustee. No Bonds
shall be authenticated in lieu of or in exchange for any Bonds canceled as
provided in this Section, except as expressly permitted by this Indenture.
Subject to Section 2.6(d), all canceled Bonds may be held or disposed of by the
Indenture Trustee in accordance with its standard retention or disposal policy
as in effect at the time unless the Issuer shall direct by an Issuer Order that
they be returned to it; provided that such Issuer Order is timely and the Bonds
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 Trust
Property from the lien created by this Indenture and deposit in the Collection
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 Bonds. The Bonds, upon original issuance,
will be issued in the form of typewritten Bonds representing the Book-Entry
Bonds, to be delivered to The Depository Trust Company or its custodian, the
initial Clearing Agency, by, or on behalf of, the Issuer. Such Bonds shall
initially be registered on the Bond Register in the name of Cede & Co., the
nominee of the initial Clearing Agency, and no Bond Owner will receive a
Definitive Bond representing such Bond Owner's interest in such Bond, except as
provided in Section 2.11. Unless and until definitive, fully registered Bonds
(the "Definitive Bonds") have been issued to Bond Owners pursuant to Section
2.11:

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

                  (ii)  the Bond 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 Bonds
      and the giving of instructions or directions hereunder) as the sole Holder
      of the Bonds, and shall have no obligation to the Bond Owners;

                                       8
<PAGE>

                  (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 Bond Owners shall be exercised only
      through the Clearing Agency and shall be limited to those established by
      law and agreements between such Bond Owners and the Clearing Agency and/or
      the Clearing Agency Participants. Unless and until Definitive Bonds 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 Bonds to such
      Clearing Agency Participants;

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

                  (vi)  Bond Owners may receive copies of any reports sent to
      Bondholders pursuant to this Indenture, upon written request, together
      with a certification that they are Bond 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 Bondholders is required under this Indenture, unless and
until Definitive Bonds shall have been issued to Bond 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 Bonds to the Clearing Agency, and
shall have no obligation to the Bond Owners.

            SECTION 2.11. Definitive Bonds. If (i) the Servicer 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 Bonds, and
the Servicer is unable to locate a qualified successor, (ii) the Servicer at its
option advises the Indenture Trustee in writing that it elects to terminate the
book-entry system through the Clearing Agency or (iii) after the occurrence of a
Rapid Amortization Event, Bond Owners representing beneficial interests
aggregating at least a majority of the Outstanding Amount of the Bonds 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 Bond Owners, then the Clearing Agency shall notify all
Bond Owners and the Indenture Trustee of the occurrence of any such event and of
the availability of Definitive Bonds to Bond Owners requesting the same. Upon
surrender to the Indenture Trustee of the typewritten Bond or Bonds representing
the Book-Entry Bonds by the Clearing Agency, accompanied by registration
instructions, the Issuer shall execute and the Indenture Trustee shall
authenticate the Definitive Bonds in accordance with the instructions of the
Clearing Agency. None of the Issuer, the Bond Registrar or the Indenture Trustee
shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be

                                       9
<PAGE>

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

                                  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 Bonds in accordance with
the terms of the Bonds and this Indenture. The Bonds shall be debt obligations
of the Trust and shall be limited in right of payment to amounts available from
the Trust as provided in this Indenture and the Trust shall not otherwise be
liable for payments on the Bonds. No person shall be personally liable for any
amounts payable under the Bonds. Amounts properly withheld under the Code by any
Person from a payment to any Bondholder of interest and/or principal shall be
considered as having been paid by the Issuer to such Bondholder for all purposes
of this Indenture.

            SECTION 3.2. Maintenance of Office or Agency. The Issuer will
maintain in [___________], an office or agency where Bonds may be surrendered
for registration, transfer or exchange of the Bonds, and where notices and
demands to or upon the Issuer in respect of the Bonds and this Indenture may be
served. The Issuer hereby initially appoints the Indenture Trustee 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, 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 Bond Paying Agent other than the Indenture Trustee to execute and
deliver to the Indenture Trustee and the Insurer an instrument in which such
Bond Paying Agent shall agree with the Indenture Trustee (and if the Indenture
Trustee acts as Bond Paying Agent, it hereby so agrees), subject to the
provisions of this Section, that such Bond Paying Agent will:

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

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

                  (iii) at any time during the continuance of any such default,
      upon the written request of the Indenture Trustee 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 Bond Paying Agent;

                                       10
<PAGE>

                  (iv)  immediately resign as a Bond Paying Agent and forthwith
      pay to the Indenture Trustee all sums held by it in trust for the payment
      of Bonds if at any time it ceases to meet the standards required to be met
      by a Bond 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 Bonds 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 Bond Paying Agent to pay to the Indenture Trustee all sums held
in trust by such Bond 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 Bond
Paying Agent; and upon such a payment by any Bond Paying Agent to the Indenture
Trustee, such Bond 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 Bond Paying Agent in trust for the
payment of any amount due with respect to any Bond 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
Collection Account; and the Holder of such Bond shall thereafter, as an
unsecured general creditor, look only to the Issuer for payment thereof (but
only to the extent of the amounts so paid to the Issuer), and all liability of
the Indenture Trustee, the Insurer or such Bond 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 Bonds, 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.

            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 Trust Property, the Bonds, and each other
instrument or agreement included in the Trust Property.

            SECTION 3.5. Protection of Trust Property. 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 Trust Property
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 Trust Property.
The Issuer will from time to time prepare (or shall cause to be prepared),
execute and deliver all such

                                       11
<PAGE>

supplements and amendments hereto and all such financing statements,
continuation statements, instruments of further assurance and other instruments,
and will take such other action necessary or advisable to:

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

                  (ii)  maintain or preserve the lien and security interest (and
      the priority thereof) in favor of the Indenture Trustee for the benefit of
      the Issuer Secured Parties created by this Indenture or carry out more
      effectively the purposes hereof;

                  (iii) perfect, publish notice of or protect the validity of
      any Grant made or to be made by this Indenture;

                  (iv)  enforce any of the Collateral;

                  (v)   preserve and defend title to the Trust Property and the
      rights of the Indenture Trustee in such Trust Property against the claims
      of all persons and parties; and

                  (vi)  pay all taxes or assessments levied or assessed upon the
      Trust Property 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 be deemed to create a duty in the Indenture Trustee to
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 Trust Property.

            (a)   On the Closing Date, the Issuer shall furnish to the
Indenture Trustee and the Insurer an Opinion of Counsel in the form of Exhibit B
hereto, stating that, in the opinion of 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 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,
beginning in 200_, the Issuer shall furnish to the Indenture Trustee and the
Insurer, an Opinion of Counsel either stating that, in the opinion of such
counsel, such actions have been taken with respect to the recording, filing,
re-recording and refiling 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
maintain the lien and security interest created by this Indenture 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

                                       12
<PAGE>

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
Indenture.

            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 Trust Property 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
Servicer to assist the Issuer in performing its duties under this Indenture.

            (c)   The Issuer will punctually perform and observe all of its

be filed) all UCC financing statements and continuation statements required to
be filed by the terms of this Indenture and the Sale and Servicing Agreement in

actual knowledge of the occurrence of an Event of Servicing Termination under

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 (y) if the
effect thereof would adversely affect the Holders of the Bonds.

      Bondholders representing 66-2/3% of the Outstanding Amount may direct the
      Indenture Trustee to sell or dispose of the Trust Property.

                  (ii)  claim any credit on, or make any deduction from the

      taxes levied or assessed upon any part of the Trust Property; or

      Trustee created by this Indenture to be amended, hypothecated,

      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 Trust Property or (D) amend, modify or fail to comply with the

                  (ii)  the Holders of not less than 50% of the Outstanding
      Amount of the related Bonds have made written request to the Indenture

      hereunder;

                  (iii) such Holder or Holders have offered to the Indenture
      Trustee indemnity reasonably satisfactory to it against the costs,

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

                  (v)   no direction inconsistent with such written request has

<PAGE>

            SECTION 5.4. Restoration of Rights and Remedies. If the Indenture
Trustee or any Bondholder has instituted any proceeding to enforce any right or
remedy under this Indenture and such proceeding has been discontinued or
abandoned for any reason, then and in every such case the Issuer, the Insurer,
the Indenture Trustee and the Bondholders shall, subject to any determination in
such proceeding, be restored severally and respectively to their former
positions hereunder, and thereafter all rights and remedies of the Indenture
Trustee, the Insurer and the Bondholders shall continue as though no such
proceeding had been instituted.

herein conferred upon or reserved to the Controlling Party or to the related
Bondholders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

the Indenture Trustee, the Insurer or any Holder of any Bond 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 Bondholders may be exercised
from time to time, and as often as may be deemed expedient, by the Indenture
Trustee, the Insurer or by the Bondholders, as the case may be.

of the Outstanding Amount of the related Bonds) 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 12.1 hereof with respect to the
Bonds or exercising any trust or power conferred on the Indenture Trustee;
provided that:

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

                  (ii)  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 Bondholders not consenting to such
action.

            SECTION 5.8. Undertaking for Costs. All parties to this Indenture
agree, and each Holder of any Bond by such Holder's acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, 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

                                       20
<PAGE>

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 Bondholder, or group of Bondholders 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 Bonds or (c) any suit instituted by any Bondholder for
the enforcement of the payment of principal of or interest on any Bond on or
after the respective due dates expressed in such Bond 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 Bonds. The Indenture Trustee's right to seek
and recover judgment on the Bonds or under this Indenture shall not be affected
by the seeking, obtaining or application of any other relief under or with
respect to this Indenture. Neither the lien of this Indenture nor any rights or
remedies of the Indenture Trustee, the Insurer or the Bondholders 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 Trust Property or upon any of the assets of the Issuer.

            SECTION 5.11. Performance and Enforcement of Certain Obligations.

            (a)   Promptly following a request from the Indenture Trustee (at
the direction of the Insurer) to do so and at the Servicer'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 (i) an Insurer Default has occurred and is
continuing or (ii) a Rapid Amortization Event described in clause (g) of Section
12.1 has occurred and is continuing, the Holders of 66-2/3% of the Outstanding
Amount of the Bonds) shall, exercise all rights, remedies, powers, privileges
and claims of the Issuer against the Depositor or the Servicer under or in
connection

                                       21
<PAGE>

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 Bondholder 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 Bonds, 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 Bonds 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 Bonds 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 Insured Amount on a
Bond 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 Bonds by mail that, in the event that any
Bondholder's payment is so recoverable, such Bondholder 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 Bonds, if
any, which have been made by the Indenture Trustee and subsequently recovered
from Bondholders 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
Bondholder 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 Bondholders and not to the Indenture Trustee, any Bondholder
directly (unless such Bondholder has returned principal or interest paid on the
Bonds to such receiver or trustee in bankruptcy, in which case the Insurer shall
make such payment to the Indenture Trustee for payment to such Bondholder 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 Bonds. Each
Holder, by its purchase of Bonds, 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

                                       22
<PAGE>

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 Bondholder and the Indenture Trustee
hereby delegate and assign, to the fullest extent permitted by law, the rights
of the Indenture Trustee and each Bondholder 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. Bondholder Rights. Each Bondholder by the acceptance
of its Bond 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 Bond 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 Bondholder hereunder without any further
consent of the Bondholder. So long as no Insurer Default has occurred and is
continuing, the Bondholders may only exercise such rights with the consent of
the Insurer.

            SECTION 5.15. Insurer's Rights Regarding Actions, Proceedings or
Investigations. Until all Bonds 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)   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 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, 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 Bondholder.

                                       23
<PAGE>

            (c)   The Indenture Trustee hereby agrees to provide to the Insurer
prompt written notice of any action, proceeding or investigation 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 Bondholder, by acceptance of its Bond, 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 Bondholder 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.

                                   ARTICLE VI

                              The Indenture Trustee

            SECTION 6.1. Duties of Indenture Trustee.

            (a)   If a Rapid Amortization Event 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; provided, however, that if the
Indenture Trustee is acting as Servicer, it shall use the same degree of care
and skill as is required of the Servicer under the Sale and Servicing Agreement.

            (b)   Except during the continuance of a Rapid Amortization Event

                  (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.

                                       24
<PAGE>

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

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

                  (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 good faith in accordance with a
      direction received by it pursuant to Section 5.12; and

                  (iv)  the Indenture Trustee shall not be charged with
      knowledge of any failure by the Servicer to comply with the obligations of
      the Servicer referred to in clause (ii) of Section 6.01 of the Sale and
      Servicing Agreement unless a Responsible Officer of the Indenture Trustee
      at the Corporate Trust Office obtains actual knowledge of such failure or
      occurrence or the Indenture Trustee receives written notice of such
      failure or occurrence from the Servicer, the Insurer or the Holders of
      Bonds 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, 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 Bonds, 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 Bonds, with the Indenture
Trustee's officers and employees responsible for carrying out the Indenture
Trustee's duties with respect to the Bonds.

            (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.

                                       25
<PAGE>

            (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 Bondholders.

            (j)   In no event shall [Indenture Trustee], in any of its
capacities hereunder, be deemed to have assumed any duties of the Owner Trustee
under the Delaware Business Trust Statute, common law, or the Trust Agreement.

            SECTION 6.2. Rights of Indenture Trustee.

            (a)   The Indenture Trustee may conclusively rely on any 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 the document.

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

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

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

            (f)   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
Bonds or the Controlling Party, pursuant to the provisions of this Indenture,
unless such Holders of Bonds 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, upon the occurrence of a
Rapid Amortization Event or Event of Servicing Termination as defined in the
Sale and Servicing Agreement (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.

                                       26
<PAGE>

            (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, 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 Bonds evidencing not less than 25% 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.

            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 Bonds and may otherwise deal with the Issuer or its Affiliates with the same
rights it would have if it were not Indenture Trustee. Any Bond Paying Agent,
Bond Registrar, co-registrar or co-paying agent may do the same with like
rights. However, the Indenture Trustee must comply with Sections 6.11 and 6.12.

            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 Trust Property or the Bonds, it shall not be
accountable for the Issuer's use of the proceeds from the Bonds, and it shall
not be responsible for any statement of the Issuer in the Indenture or in any
document issued in connection with the sale of the Bonds or in the Bonds other
than the Indenture Trustee's certificate of authentication.

            SECTION 6.5. 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 it is either known by, or written
notice of the existence thereof has been delivered to, a Responsible Officer of
the Indenture Trustee, 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 Bondholder notice of such event. Except in the case
of a default in payment of principal of or interest on any Bond, the Indenture
Trustee may withhold the notice to the Bondholders if and so long as one of its
Responsible Officers in good faith determines that withholding the notice is in
the interests of Bondholders; provided that the Indenture Trustee shall not
withhold any such notice to the Insurer.

            SECTION 6.6. Reports by Indenture Trustee to Holders. Upon written
request, the Bond Paying Agent or the Servicer shall on behalf of the Issuer
deliver to each Bondholder such information as may be reasonably required to
enable such Holder to prepare its federal and state income tax returns required
by law.

                                       27
<PAGE>

            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 Servicer to, pay to the Indenture Trustee
from time to time compensation as agreed to in writing between the Servicer 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 shall or shall cause the Servicer to reimburse the Indenture
Trustee for all reasonable out-of-pocket expenses incurred or made by it,
including 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,
accountants and experts. The Issuer shall or shall cause the Servicer to
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 and the Servicer promptly of any claim for which it may seek
indemnity. Failure by the Indenture Trustee to so notify the Issuer and the
Servicer shall not relieve the Issuer of its obligations hereunder or the
Servicer of its obligations under Article VIII of the Sale and Servicing
Agreement. The Issuer shall or shall cause the Servicer to defend the claim, the
Indenture Trustee may have separate counsel and the Issuer shall or shall cause
the Servicer to pay the fees and expenses of such counsel. Neither the Issuer
nor the Servicer 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.

            (b)   The Issuer'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 Servicer) to the Indenture Trustee hereunder and under the Basic
Documents shall be recourse to the Trust Property only and specifically shall
not be recourse to the assets of the Issuer or any Bondholder. In addition, the
Indenture Trustee agrees that its recourse to the Issuer, the Trust Property and
the Depositor shall be limited to the right to receive the distributions
referred to in Section 8.7 herein.

            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 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 Servicer. 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

                                       28
<PAGE>

     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 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, the
Insurer may appoint 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 Bondholders. 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 Bonds may, at the expense of the Servicer, petition
any court of competent jurisdiction for the appointment of a successor Indenture
Trustee acceptable to the Insurer.

                                       29
<PAGE>

            If the Indenture Trustee fails to comply with Section 6.11, any
Bondholder 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 and the Servicer's indemnity obligations under
Section 6.7 shall continue for the benefit of the retiring Indenture Trustee and
the Servicer 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

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 Insurer and the Servicer
with at least 30 days 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 Bonds shall have been authenticated but not
delivered, any such successor to the Indenture Trustee may adopt the certificate
of authentication of any predecessor trustee, and deliver such Bonds so
authenticated; and in case at that time any of the Bonds shall not have been
authenticated, any successor to the Indenture Trustee may authenticate such
Bonds either in the name of any predecessor hereunder or in the name of the
successor to the Indenture Trustee; and in all such cases such certificates
shall have the full force which it is anywhere in the Bonds or in this
Indenture.

with the consent of the Insurer, 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 Bondholders, 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;

                  (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 Servicer acting jointly
      may at any time accept the resignation of or remove any separate trustee
      or co-trustee except that following the occurrence of an Event of
      Servicing Termination, the Indenture Trustee acting alone may 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 Servicer shall be responsible for the fees of any
co-trustee or separate trustee appointed hereunder.

(which may be a sub-account of the Collection Account) for the benefit of the
Bondholders 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 Bondholders 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 Bondholders in
accordance with Section 8.7(b). 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 Bonds to be
paid from funds transferred from the Policy Payment Account shall be noted as
provided in subsection (d) of this Section 8.4 in the Bond Register and in the
Indenture Trustee's Statement to Bondholders. 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

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 Bonds,
furnish to the Insurer a notice of such retirement, and, upon retirement of the
Bonds, and, upon retirement of the Bonds and the expiration of the term of the
Policy surrender the Policy to the Insurer for cancellation.

shall prepare or cause to be prepared and shall forward to the Indenture Trustee
the information set forth in clauses (i) and (ii) above aggregated for such
calendar year. Such obligation of the Servicer shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Servicer or a Bond Paying Agent pursuant to any requirements of
the Code.

            SECTION 8.9. Indenture Trustee Annual Certification. On or before
January 31 of each year, the Manager, on behalf of the Trust, shall provide the
Indenture Trustee with a written notice listing all Payment Date reports to

such prior calendar year, no written notice shall be required. No later than
March 15 of each year in which such written notice is provided by the Manager to
the Indenture Trustee, the Indenture Trustee shall sign a certification (in the

Insurer shall receive at least seven days' notice when requested by the Issuer
to take any action pursuant to Section 8.2(a), accompanied by copies of any
instruments involved, and the Indenture Trustee shall also require as a
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,
outlining the steps required to complete the same, and concluding that all
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 Bonds
or the rights of the Bondholders 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 Trust
Property. 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.

in form satisfactory to the Indenture Trustee and the Insurer, for any of the
following purposes:

                  (i)   to correct or amplify the description of any property at
      any time subject to the lien of this Indenture, or better to assure,

                  (vi)  to evidence and provide for the acceptance of the
      appointment hereunder by a successor trustee with respect to the Bonds and

indenture or indentures supplemental hereto for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or of modifying in any manner the rights of the Holders of
the Bonds under this Indenture; provided, however, that such action shall not,
as evidenced by an Opinion of Counsel, adversely affect in any material respect
the interests of any Bondholder.

            SECTION 9.2. Supplemental Indentures with Consent of Bondholders.
The parties hereto, when authorized by an Issuer Order, also may, with prior
notice to the Rating Agencies, with the consent of the Insurer and with the
consent of the Holders of not less than a majority of the Outstanding Amount of
the Bonds, by Act of such Holders delivered to the parties hereto, enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or of modifying in any manner the rights of the Holders of

                  (i)   change the date of payment of any installment of
      principal of or interest on any Bond, or reduce the principal amount
      thereof, the interest rate thereon or the Redemption Price with respect
      thereto, change the provision of this Indenture relating to the
      application of collections on, or the proceeds of the sale of, the Trust
      Property to payment of principal of or interest on the Bonds, or change

                  (ii)  impair the right to institute suit for the enforcement
      of the provisions of this Indenture requiring the application of funds

      in the case of redemption, on or after the Redemption Date);

                  (iii) reduce the percentage of the Outstanding Amount of the
      Bonds, the consent of the Holders of which is required for any such

<PAGE>

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

                  (vii) modify any of the provisions of this Indenture in such
      manner as to affect the calculation of the amount of any payment of
      interest or principal due on any Bond on any Payment Date (including the
      calculation of any of the individual components of such calculation); or

                  (viii) permit the creation of any lien ranking prior to or on
      a parity with the lien of this Indenture with respect to any part of the
      Trust Property or, except as otherwise permitted or contemplated herein or
      in any of the Basic Documents, terminate the lien of this Indenture on any
      property at any time subject hereto or deprive the Holder of any Bond of
      the security provided by the lien of this Indenture.

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

            Promptly after the execution by the parties hereto of any
supplemental indenture pursuant to this Section, the Indenture Trustee shall
mail to the Holders of the Bonds to which such amendment or supplemental
indenture relates a notice setting forth in general terms 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 Bond)
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 Bonds affected thereby,

                                       45
<PAGE>

and the respective rights, limitations of rights, obligations, duties,
liabilities and immunities under this Indenture of the Indenture Trustee, the
Issuer and the Holders of the Bonds shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments, and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture
for any and all purposes.

            SECTION 9.5. Reference in Bonds 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 Bonds to Supplemental Indentures. Bonds
authenticated and delivered after the execution of any supplemental indenture
pursuant to this Article IX may, and if required by the Indenture Trustee shall,
bear a notation in form approved by the Indenture Trustee as to any matter
provided for in such supplemental indenture. If the Issuer or the Indenture
Trustee shall so determine, new Bonds so modified as to conform, in the opinion
of the Indenture Trustee and the Issuer, to any such supplemental indenture may
be prepared and executed by the Issuer and authenticated and delivered by the
Indenture Trustee in exchange for Outstanding Bonds.

Section 7.01(b), for a purchase price equal to the Redemption Price. The
Servicer or the Issuer shall furnish the Insurer notice of such redemption not
later than 35 days prior to the Redemption Date. If the Bonds are to be redeemed
pursuant to this Section 10.1, the Servicer 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 Collection Account the
Redemption Price of such Bonds whereupon all such Bonds shall be due and payable
on the Redemption Date upon the furnishing of a notice complying with Section
10.2 (unless the Issuer shall default in the deposit of the Redemption Price).

            SECTION 10.2. Surrender of Bonds.

            (a)   Notice of any termination, specifying the Payment Date (which
shall be a date that would otherwise be a Payment Date) upon which the
Bondholders may surrender their Bonds to the Indenture Trustee for payment of
the final distribution and cancellation, shall be given promptly by the
Indenture Trustee (upon receipt of written directions from the Depositor, if the
Depositor is exercising its right to transfer of the Mortgage Loans, given not
later than the first day of the month preceding the month of such final
distribution) to the Insurer and to the Servicer and by letter to Bondholders
mailed not earlier than the 15th day and not later than the

distribution and (iii) that the Record Date otherwise applicable to such Payment
Date is not applicable, distributions being made only upon presentation and
surrender of the Bonds at the office or agency of the Indenture Trustee therein
specified. In the event written directions are delivered by the Depositor to the
Indenture Trustee as described in the preceding sentence, the Depositor shall
deposit in the Collection 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 Bondholders,
will be equal to the retransfer amount for the Mortgage Loans computed as above
provided, together with all 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.

Trustee shall cause to be distributed to the Holders of Bonds on the Payment
Date for such final distribution, in proportion to the Percentage Interests of
their respective Bonds and to the extent that funds are available for such
purpose, the amount required to be distributed to Bondholders pursuant to
Section 10.1 of this Indenture for such Payment Date. The distribution on such
final Payment Date pursuant to a retransfer 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 Bonds. On the final
Payment Date prior to having made the distributions called for above, the
Indenture Trustee shall, based upon the information set forth in the Servicing
Certificate for such Payment Date, withdraw from the Collection Account and
remit to the Insurer the lesser of (x) the amount available for distribution on
such final Payment Date, net of any portion thereof necessary to pay the amounts
described in clauses (i) and (ii) above 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 Bondholders shall not surrender
their Bonds for final payment and cancellation on or before such final Payment
Date, the Indenture Trustee shall on such date cause all funds in the Collection
Account not distributed in final distribution to Bondholders to be withdrawn
therefrom and credited to the remaining Bondholders by depositing such funds in
a separate escrow account for the benefit of such Bondholders and the Depositor
(if the Depositor 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 Bondholders to surrender their Bonds for cancellation and receive
the final distribution with respect thereto. If within one year after the second
notice all the Bonds 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 Bondholders concerning surrender of
their Bonds, and the cost thereof shall be paid out of the funds on deposit in
such escrow account.

            SECTION 10.3. Form of Redemption Notice. Notice of redemption
supplied to the Indenture Trustee by the Depositor under Section 10.1 shall be
given by the Indenture

                                       47
<PAGE>

Trustee by facsimile or by first-class mail, postage prepaid, transmitted or
mailed prior to the applicable Redemption Date to each Holder of Bonds of
record, as of the close of business on the date which is not less than 5 days
prior to the applicable Redemption Date, at such Holder's address appearing in
the Bond Register.

            All notices of redemption shall state:

                  (i)   the Redemption Date;

                  (ii)  the Redemption Price;

                  (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 Bonds at the place where such
      Bonds 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

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

            Notice of redemption of the Bonds 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 Bond shall not impair or
affect the validity of the redemption of any other Bond.

            SECTION 10.4. Bonds Payable on Redemption Date. The Bonds to be
redeemed shall, following notice of redemption as required by Section 10.2, on
the Redemption Date become due and payable at the Redemption Price 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

                                  Miscellaneous

            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.

                                       48
<PAGE>

            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

                  (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.

            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

                                       49
<PAGE>

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 Bondholders.

            (a)   Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Bondholders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Bondholders in person or by agents
duly appointed in writing; and except as herein otherwise expressly provided
such action shall become effective when such instrument or instruments are
delivered to the Indenture Trustee, and, where it is hereby expressly required,
to the Issuer. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the
Bondholders signing such instrument or instruments. Proof of execution of any
such instrument or of a writing appointing any such agent shall be sufficient
for any purpose of this Indenture and (subject to Section 6.1) 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 Bonds shall be proved by the Bond Register.

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

            SECTION 11.4. Notices, etc., to Indenture Trustee, Issuer, Insurer
and Rating Agencies. Any request, demand, authorization, direction, notice,
consent, waiver or Act of Bondholders 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 Bondholder or by the Issuer shall
be sufficient for every purpose hereunder if personally delivered, delivered by
overnight courier or mailed first-class and shall be deemed to have been duly
given upon receipt to the Indenture Trustee at its Corporate Trust Office and
any notice delivered by facsimile shall be addressed to the Corporate Trust
Office, telecopy number (____) ____-____, or

            (b)   The Issuer by the Indenture Trustee or by any Bondholder 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 Mortgage Trust
200_-_, in care of [Owner Trustee], [Owner Trustee's Address], or at any other
address previously furnished in writing to the Indenture

                                       50
<PAGE>

Trustee by Issuer. The Issuer shall promptly transmit any notice received by it
from the Bondholders to the Indenture Trustee.

            (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:       [Insurer]
                                  [Insurer's Address]

                                  Telecopy: (____) ____-_____

            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 [First Rating Agency], at the following address: [First Rating
Agency's Address], Fax No: (___) ____-_____ and (ii) in the case of [Second
Rating Agency], at the following address: [Second Rating Agency's Address], Fax
No: (___) ____-_____; 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 Bondholders; Waiver. Where this Indenture
provides for notice to Bondholders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class, postage prepaid to each Bondholder affected by such
event (and in all cases, the Insurer shall receive notice), at his address as it
appears on the Bond Register, not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice. In any case
where notice to Bondholders is given by mail, neither the failure to mail such
notice nor any defect in any notice so mailed to any particular Bondholder shall
affect the sufficiency of such notice with respect to other Bondholders, and any
notice that is mailed in the manner herein provided shall conclusively be
presumed to have been duly given.

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

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

                                       51
<PAGE>

            SECTION 11.6. Alternate Payment and Notice Provisions.
Notwithstanding any provision of this Indenture or any of the Bonds to the
contrary, the Issuer may enter into any agreement with any Holder of a Bond
providing for a method of payment, or notice by the Indenture Trustee or any
Bond 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 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
Bonds, any fact relevant to understanding the federal tax treatment of the
Bonds, 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 Bonds by the Issuer shall bind its successors and
assigns, whether so expressed or not. All agreements of the Indenture Trustee in
this Indenture shall bind its successors.

            SECTION 11.10. Separability. In case any provision in this Indenture
or in the Bonds shall be invalid, illegal or unenforceable, the validity,
legality, and enforceability of the remaining provisions shall not in any way be
affected or impaired thereby.

            SECTION 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 Bonds, express
or implied, shall give to any Person, other than the parties hereto and their
successors hereunder, the Insurer, and the Bondholders, and any other party
secured hereunder, and any other person with an ownership interest in any part
of the Trust Property, 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.

                                       52
<PAGE>

            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 Bonds or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

            SECTION 11.13. GOVERNING LAW. THIS INDENTURE SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REFERENCE TO ITS
CONFLICT OF LAW PROVISIONS (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 Trust 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 Bondholders or any other
person secured hereunder or for the enforcement of any right or remedy granted
to the Indenture Trustee under this Indenture.

            SECTION 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 Bonds or under this
Indenture or any Bond 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, 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 Bondholder, by accepting a Bond, 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

                                       53
<PAGE>

liquidation proceedings, or other proceedings under any United States Federal or
state bankruptcy or similar law in connection with any obligations relating to
the Bonds, this Indenture or any of the Basic Documents.

            SECTION 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 [Owner Trustee], 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 [Owner
Trustee] 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
[Owner Trustee] 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 [Owner Trustee] 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

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

            (a)   failure on the part of the Issuer, 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, within two 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 Issuer, 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 Issuer, the Depositor or the Servicer, as the case
may be, by the

                                       54
<PAGE>

Indenture Trustee, or to the Issuer, the Depositor or the Servicer, as the case
may be, and the Indenture Trustee by the Insurer or Holders of Bonds evidencing
more than 50% of the Outstanding Amount;

            (b)   any representation or warranty made by the Issuer, 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 Bondholders 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 Bondholders 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 Issuer, the
Depositor or the Servicer, as the case may be, by the Indenture Trustee, or to
the Issuer, the Depositor or the Servicer, as the case may be, and the Indenture
Trustee by either the Insurer or the Holders of Bonds evidencing more than 50%
of the Outstanding Amount; provided, however, that with respect to any such
representation or warranty made with respect to the related Mortgage Loans, a
Rapid Amortization Event pursuant to this subparagraph (b) shall not be deemed
to have occurred hereunder if the Servicer or the Depositor has accepted
retransfer of such related Mortgage Loan or related Mortgage Loans during such
period (or such longer period not to exceed an additional 60 days as the
Indenture Trustee may specify with the consent of the Insurer) in accordance
with the provisions hereof;

            (c)   the Servicer, the Depositor or the Issuer or any of their
Subsidiaries o r 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 Servicer, the Depositor or the Trust
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
Servicer, the Depositor of the Trust and such decree or order shall have
remained in force undischarged or unstayed for a period of 30 days; or the
Servicer, the Depositor or the Trust 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 with respect to any Class;

            (f)   an Event of Servicing Termination has occurred;

            (g)   a default in the payment of any Deferred Interest on the Class
A Bonds on the Final Maturity Date; and

                                       55
<PAGE>

            (h)   default in the payment of any interest, principal or any
installment of principal on the Bonds when the same becomes due and payable, and
such default continues for a period of five Business Days.

            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 Class A
Bonds evidencing more than 50% of the outstanding principal balance of the Class
A Bonds, in each case with the prior written consent of the Insurer (so long as
no Insurer Default has occurred and is continuing or unless a Rapid Amortization
Event described in clause (g) above has occurred) or the Insurer (so long as no
Insurer Default has occurred and is continuing), by written notice to the Trust,
the Insurer, the Depositor, and the Servicer (and to the Indenture Trustee, if
given by the Bondholders or the Insurer) declare that a Rapid Amortization Event
has occurred as of the date of such notice.

            If so directed by the Insurer, so long as no Insurer Default has
occurred and is continuing, the Indenture Trustee will and the Insurer (so long
as no Insurer Default has occurred and is continuing) or Holders holding Class A
Bonds evidencing more than 50% of the outstanding principal balance of the Class
A Bonds (if a Rapid Amortization Event described in clause (g) above has
occurred) shall have the right to direct the Indenture Trustee to sell, dispose
of or otherwise liquidate the Trust Property with respect to the Mortgage Loans
in a commercially reasonable manner and on commercially reasonable terms. So
long as no Event of Servicing Termination has occurred and is continuing, any
such sale, disposal or liquidation will be "servicing retained" by the Servicer.
With respect to the Bonds, the net proceeds of such sale will be paid (i) first,
to the Holders of the Bonds insofar as may be necessary to reduce the principal
balance of such Class, together with all accrued and unpaid interest due
thereon, to zero, (ii) second, to reimburse the Insurer to the extent of
unreimbursed draws under the Policy and other amounts owing to the Insurer, and
(iii) third, to the Residual Certificateholder.

            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 Bonds of the occurrence of such event.

                          COLLATERALIZED MORTGAGE BONDS

            Sequoia Mortgage Trust 200_-_, 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 ________________________ MILLION
DOLLARS ($____________), 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 Collection Account in respect of
principal on the Class A Bonds pursuant to Section 8.7 of the Indenture;
provided, however, that the entire unpaid principal amount of this Class A Bond
shall be due and payable on the Payment Date in _______ 20__ (the "Final
Scheduled Payment Date"). The Issuer will pay interest on this Bond at the rate
per annum provided in the Indenture on each Payment Date on the principal amount
of this Class A Bond outstanding on the preceding Payment Date (after giving
effect to all payments of principal made on the preceding Payment Date).
Interest on this Class A Bond will accrue for each Payment Date 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 ______, 200_. 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 Class A Bond shall be paid in the
manner specified on the reverse hereof.

            The principal of and interest on this Class A Bond 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 Class A Bond shall be applied first to interest
due and payable on this Class A Bond as provided above and then to the unpaid
principal of this Class A Bond.

            The Bonds are entitled to the benefits of a financial guaranty
insurance policy (the "Policy") issued by [Insurer] (the "Insurer"), pursuant to
which the Insurer has unconditionally guaranteed payments of the Insured Amounts
with respect to the Class A Bonds 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 Bonds as indebtedness of
the Depositor and hereby instructs the Indenture Trustee to treat the Bonds as
indebtedness of the Depositor for federal and state tax reporting purposes. Each
Bondholder by acceptance of a Bond (and each owner of a beneficial interest in a
Bond by acceptance of such beneficial interest) agrees to treat the Bonds for
federal income, state and local income and franchise and any other income taxes
as indebtedness of the Depositor.

            Each Bondholder or Bond Owner, by acceptance of this Class A Bond
or, in the case of a Bond Owner, a beneficial interest in a Bond, 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
Class A Bonds or under the Indenture or any certificate or other writing
delivered in connection therewith, against (i) the Depositor, the Servicer, the
Indenture

                                      A-1-2

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 or employee 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.

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

            Unless the certificate of authentication hereon has been executed by
the Indenture Trustee whose name appears below by manual signature, this Class A
Bond 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 Class A Bond is one of a duly authorized issue of Bonds of the
Issuer, designated as its Collateralized Mortgage Bonds (herein called the
"Class A Bonds"), all issued under an Indenture dated as of _______, 200_ (such
agreement, as supplemented or amended, is herein called the "Indenture"),
between the Issuer and [Indenture Trustee], as Indenture Trustee (the "Indenture
Trustee"), which term includes any successor Indenture Trustee under the
Indenture.

            All terms used in this Class A Bond 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 _______, 200_ (such trust agreement, as supplemented or
amended is herein called the "Trust Agreement"), between Sequoia Mortgage
Funding Corporation, as Depositor, and [Owner Trustee], as Owner Trustee (the
"Owner Trustee," which term includes any successor Owner Trustee under the Trust
Agreement), as so supplemented or amended.

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

            Principal of the Class A Bonds will be payable on each Payment Date
in an amount described in the Indenture. "Payment Date" means the fifteenth day
of each month, or, if any such date is not a Business Day, the next succeeding
Business Day, commencing _____, 200_. The term "Payment Date," shall be deemed
to include the Final Scheduled Payment Date.

            As described above, the entire unpaid principal amount of this Class
A Bond shall be due and payable on the earlier of the Final Scheduled Payment
Date and the Redemption

                                     A-1-3
<PAGE>

Date, if any, pursuant to Section 10.1 of the Indenture. Notwithstanding the
foregoing, on the date on which a Rapid Amortization Period as described in
Section 5.1(a) shall have occurred and be continuing and, in the limited
instances specified in the Indenture, the Holders representing more than 50% of
the Outstanding Amount of the Class A Bonds, with the prior written consent of
the Insurer (so long as there is no continuing Insurer Default) shall have the
right among others to direct the Indenture Trustee to sell or liquidate the
Mortgage Loans as provided in Section 12.1 of the Indenture and pay such amounts
to the Holders of the Class A Bonds. All principal payments on the Class A Bonds
shall be made pro rata to the Holders of the Class A Bonds entitled thereto.

            Payments of interest on this Class A Bond due and payable on each
Payment Date, together with the installment of principal, if any, to the extent
not in full payment of this Class A Bond, shall be made by check mailed to the
Person whose name appears as the Holder of this Class A Bond (or one or more
Predecessor Bonds) on the Bond Register as of the close of business on each
Record Date, except that with respect to Class A Bond 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. Such checks shall be
mailed to the Person entitled thereto at the address of such Person as it
appears on the Bond Register as of the applicable Record Date without requiring
that this Bond be submitted for notation of payment. Any reduction in the
principal amount of this Bond (or any one or more Predecessor Bonds) effected by
any payments made on any Payment Date shall be binding upon all future Holders
of this Class A Bond and of any Class A Bond 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 Class A
Bond 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 Class A Bond at the office designated by the Indenture Trustee
for such purposes located in The City of ________.

            The Issuer shall pay interest on overdue installments of interest at
the Class A-1 Interest Rate to the extent lawful.

            As provided in the Indenture, the Class A Bonds may be redeemed
pursuant to Section 10.1 of the Indenture, in whole, but not in part, at the
option of the Depositor (with the consent of the Insurer under certain
circumstances), on any Payment Date after the Payment Date on which the Bond
Principal Balance is less than or equal to 10% of the Pool Balance, after taking
into account all distributions made on such Payment Date.

            As provided in the Indenture and subject to certain limitations set
forth therein, the transfer of this Class A Bond may be registered on the Bond
Register upon surrender of this Class A Bond 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 requirements of the Bond Registrar
which requirements include membership or

                                     A-1-4
<PAGE>

participation in Bonds 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 Bonds 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 Class A Bond, 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 Bondholder or Bond Owner, by acceptance of a Bond or, in the
case of a Bond Owner, a beneficial interest in a Bond 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
Bonds or under the Indenture or any certificate or other writing delivered in
connection 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 owner, beneficiary, agent,
officer, director or employee 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.

            Each Bondholder or Bond Owner, by acceptance of a Bond or, in the
case of a Bond Owner, a beneficial interest in a Bond covenants and agrees that
by accepting the benefits of the Indenture and the Trust Agreement that such
Bondholder 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 Bonds, the Trust
Agreement, the Indenture or the Basic Documents.

            Prior to the due presentment for registration of transfer of this
Bond, the Issuer, the Indenture Trustee and the Insurer and any agent of the
Issuer, the Indenture Trustee or the Insurer may treat the Person in whose name
this Bond (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 Bond 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 Bond under the Indenture at any time
by the Issuer with the consent of the Insurer and of the Holders of Bonds
representing a majority of the Outstanding Amount of all Bonds at the time
Outstanding. Any such consent or waiver by the Holder of this Bond (or any

                                     A-1-5
<PAGE>

one of more Predecessor Bonds) shall be conclusive and binding upon such Holder
and upon all future Holders of this Bond and of any Bond issued upon the
registration of transfer hereof or in exchange hereof or in lieu hereof whether
or not notation of such consent or waiver is made upon this Bond. 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
Bonds issued thereunder but with the consent of the Insurer.

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

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

            This Bond, the Trust Agreement 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.

            No reference herein to the Trust Agreement or the Indenture and no
provision of this Bond, 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 Bond 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
[Owner Trustee] in its individual capacity, any owner of a beneficial interest
in the Issuer, nor any of their respective beneficiaries, agents, officers,
directors, 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 Bond 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 Bond 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 with respect to
the Class A Bonds 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 Bond.

                                   ARTICLE II

                          CONVEYANCE OF MORTGAGE LOANS;
                           ORIGINAL ISSUANCE OF BONDS;
                                  TAX TREATMENT

      Section 2.01. Conveyance of Mortgage Loans; Retention of Obligation to
Fund Advances Under Credit Line Agreements.

      (a)   In consideration of the Issuer's delivery to or upon the order of
the Depositor on the Closing Date of the net proceeds from the sale of the Bonds
and the Residual Certificates and the other amounts to be distributed from time
to time to the Depositor in accordance with the terms of this Agreement, the
Depositor, concurrently with the execution and delivery of this Agreement,
hereby sells, transfers, assigns, sets over and otherwise conveys to the Issuer,
without recourse (subject to Sections 2.03, 2.05 and 2.07), all of its right,
title and interest in and to (i) each Mortgage Loan, including its Principal
Balance (including any Additional Balances related thereto) and all collections
in respect thereof received after the Cut-Off Date (excluding Interest
Collection due on or prior to the Cut-Off Date); (ii) property that secured a
Mortgage Loan that is acquired by foreclosure or deed in lieu of foreclosure;
(iii) all of the Depositor's rights under the Purchase Agreement (including all
representations and warranties of the Seller contained therein); (iv) the
Depositor's rights under the hazard insurance policies; (v) the Policy; (vi) the
Collection Account; and (vii) any proceeds of the foregoing and any other Trust
Property and all other assets included or to be included in the Trust for the
benefit of Bondholders, the Residual Certificateholders and the Insurer;
provided, however, neither the Indenture Trustee nor the Trust assumes or shall
assume the obligation under any Credit Line Agreement that provides for the
funding of future advances to the Mortgagor thereunder, and neither the Trust
nor the Indenture Trustee shall be obligated or permitted to fund any such
future advances. With respect to the HELOC Mortgage Loans, Additional Balances
shall be part of the related Principal Balance and are hereby transferred to the
Trust on the Closing Date pursuant to this Section 2.01, and therefore part of
the Trust Property. On or prior to the Closing Date, the Depositor shall cause
the Insurer to deliver the Policy to the Indenture Trustee for the benefit of
the Bondholders. It is the intention of the Depositor that the transfer and
assignment contemplated by this Agreement shall constitute a sale of the
Mortgage

                                       2

<PAGE>

Loans and other Trust Property from the Depositor to the Issuer and that such
sale should constitute a valid transfer and assignment of the Mortgage Loans and
other Trust Property to the Issuer and the beneficial interest in and title to
the Mortgage Loans and the other Trust Property shall not be part of the
Depositor's estate in the event of the filing of a bankruptcy petition by or
against the Depositor under any bankruptcy law. In the event that,
notwithstanding the intent of the Depositor, the transfer and assignment
contemplated hereby is held not to be a sale, this Agreement shall constitute a
grant of a security interest in the property referred to in this Section 2.01
for the benefit of the Bondholders, the Residual Certificateholders and the
Insurer. To the extent that the fair market value of any Additional Balance is
greater than the cash consideration paid by the Issuer for such Additional
Balance, the difference between such fair market value and the amount of such
cash consideration shall be deemed to be a capital contribution made to the
Issuer by the Depositor. To the extent that the Depositor receives cash
consideration for the entire fair market value of such Additional Balance on any
future date, any corresponding capital contribution that had previously been
deemed to have been made to the Issuer by the Depositor shall be deemed to have
been redeemed.

      (b)   Each of the Servicer and the Depositor agrees to take or cause to be
taken such actions and execute such documents (including, without limitation,
the filing of all necessary continuation statements for the UCC-1 financing
statements filed in the States of California, and Delaware, respectively, which
shall have been filed on or as of the Closing Date) describing the Cut-Off Date
Principal Balances and Additional Balances and naming (i) the Servicer as debtor
and the Depositor as secured party, and (ii) the Depositor as debtor and the
Issuer as secured party and any amendments to UCC-1 financing statements
required to reflect a change in the name or corporate structure of the Issuer,
the Servicer or the Depositor or the filing of any additional UCC-1 financing
statements due to the change in the principal office of the Servicer or the
Depositor (within 10 days of any event necessitating such filing) as are
necessary to perfect and protect the Bondholders' and the Insurer's interests in
each Cut-Off Date Principal Balance and Additional Balance and the proceeds
thereof (other than maintaining possession by the Indenture Trustee of the
Mortgage Loans and the Mortgage Files).

      (c)   In connection with such transfer and assignment, the Servicer shall
deliver to the Custodian on behalf of the Indenture Trustee the following
documents or instruments (each a "Related Document" and together for each
Mortgage Loan, the "Mortgage File") with respect to each Mortgage Loan on the
Closing Date:

            (i)       with respect to any Closed End Mortgage Loan, the original
      Mortgage Note endorsed in blank or endorsed with the following:
      "[---Servicer---] to the Sequoia Mortgage Trust 200_-_, by [Indenture
      Trustee], as trustee, for the Collateralized Mortgage Bonds, Series 200_-_
      without recourse", and with respect to any HELOC Mortgage Loan, the
      original Credit Line Agreement;

            (ii)      for each Mortgage Loan that is not a MERS Mortgage Loan,
      an unsigned and un-notarized but otherwise complete original Assignment of
      Mortgage in blank;

            (iii)     (A) for each Mortgage Loan that is not a MERS Mortgage
      Loan, the original recorded Mortgage or, if in connection with any
      Mortgage Loan, the original

                                       3

<PAGE>

      recorded Mortgage with evidence of recording thereon cannot be delivered
      on or prior to the Closing Date because of a delay caused by the public
      recording office where such original Mortgage has been delivered for
      recordation or because such original Mortgage has been lost, the Depositor
      shall deliver or cause to be delivered to the Indenture Trustee, a true
      and correct copy of such Mortgage, together with (i) in the case of a
      delay caused by the public recording office, an Officer's Certificate of
      the Depositor stating that such original Mortgage has been dispatched to
      the appropriate public recording official or (ii) in the case of an
      original Mortgage that has been lost, a certificate by the appropriate
      county recording office where such Mortgage is recorded, and (B) in the
      case of each MERS Mortgage Loan, the original Mortgage, noting the
      presence of the "Mortgage Identification Number" of such MERS Mortgage
      Loan;

            (iv)      if applicable, the original intervening assignments, if
      any ("Intervening Assignments"), with evidence of recording thereon,
      showing a complete chain of title to the Mortgage from the originator to
      the RWT Holdings, Inc. (and the endorsed in blank in accordance with
      clause (ii) above) or, if any such original Intervening Assignment has not
      been returned from the applicable recording office or has been lost, a
      true and correct copy thereof, together with (i) in the case of a delay
      caused by the public recording office, an Officer's Certificate of the
      Depositor stating that such original Intervening Assignment has been
      dispatched to the appropriate public recording official for recordation or
      (ii) in the case of an original Intervening Assignment that has been lost,
      a certificate by the appropriate county recording office where such
      Mortgage is recorded;

            (v)       either a title policy or guaranty title with respect to
      the related Mortgaged Property;

            (vi)      the original of any guaranty executed in connection with
      the Mortgage Note;

            (vii)     the original of each assumption, modification,
      consolidation or substitution agreement, if any, relating to the Mortgage
      Loans; and

            (viii)    any security agreement, chattel mortgage or equivalent
      instrument executed in connection with the Mortgage.

      The Depositor hereby confirms to the Indenture Trustee that it has caused
the portions of the Electronic Ledgers relating to the Mortgage Loans as of the
Closing Date to be clearly and unambiguously marked, and has made, or will make,
the appropriate entries in its general accounting records to indicate that such
Mortgage Loans have been transferred to the Trust. The Servicer hereby confirms
to the Indenture Trustee that it has clearly and unambiguously made appropriate
entries in its general accounting records indicating that such Mortgage Loans
constitute part of the Trust and are serviced by it on behalf of the Trust in
accordance with the terms hereof.

      (d)   Notwithstanding the characterization of the Bonds as debt for
federal, state and local income and franchise tax purposes, the parties hereto
intend to treat the transfer of the Mortgage Loans to the Trust as provided
herein as a sale, for certain non-tax purposes, of all the

                                       4

<PAGE>

Depositor's right, title and interest in and to the Mortgage Loans, whether now
existing or hereafter created, and the other property described above and all
proceeds thereof. In the event such transfer is deemed not to be a sale for such
purposes, the Depositor grants to the Trust, a security interest in all of such
party's right, title and interest in, to and under the Mortgage Loans, whether
now existing or hereafter created, and the other property described above and
all proceeds thereof; and this Agreement shall constitute a security agreement
under applicable law.

      (e)   Within 90 days following delivery of the Mortgage Files to the
Custodian on behalf of the Indenture Trustee pursuant to this Section, the
Indenture Trustee shall cause the Custodian to review on its behalf or the
Indenture Trustee shall review each such Mortgage File to ascertain that all
required documents set forth in this Section 2.01 have been executed and
received, and that such documents relate to the Mortgage Loans identified on the
Mortgage Loan Schedule and in so doing the Custodian on behalf of the Indenture
Trustee and/or the Indenture Trustee may rely on the purported due execution and
genuineness of any signature thereon. If within such 90-day period the Custodian
on behalf of the Indenture Trustee and/or the Indenture Trustee finds any
document constituting a part of a Mortgage File not to have been executed or
received or to be unrelated to the Mortgage Loans identified in said Mortgage
Loan Schedule or, if in the course of its review, the Custodian on behalf of the
Indenture Trustee and/or the Indenture Trustee determines that such Mortgage
File is otherwise defective in any material respect, the Indenture Trustee shall
promptly upon the conclusion of its review or the Custodian's review on its
behalf notify the Depositor and the Insurer, and the Depositor shall have a
period of 90 days after such notice within which to correct or cure any such
defect. Upon the completion of its 90-day review, the Custodian on behalf of the
Indenture Trustee and/or the Indenture Trustee shall also notify the Insurer of
any Mortgage File with respect to which it has been delivered any items other
than the original recorded Mortgage with respect to Section 2.01(c)(iii).

      Neither the Custodian on behalf of the Indenture Trustee nor the Indenture
Trustee shall have any responsibility for reviewing any Mortgage File except as
expressly provided in this Section 2.01. In reviewing any Mortgage File pursuant
to this Section, the Indenture Trustee and the Custodian on behalf of the
Indenture Trustee shall have no responsibility for determining whether any
document is valid and binding, whether the text of any assignment or endorsement
is in proper or recordable form (except, if applicable, to determine if the
Indenture Trustee is the assignee or endorsee), whether any document has been
recorded in accordance with the requirements of any applicable jurisdiction, or
whether a blanket assignment is permitted in any applicable jurisdiction,
whether any Person executing any document is authorized to do so or whether any
signature thereon is genuine, but shall only be required to determine whether a
document has been executed, that it appears to be what it purports to be, and,
where applicable, that it purports to be recorded.

      Upon its receipt of written notice from the Servicer or the Insurer that a
Recordation Event has occurred the Indenture Trustee shall take all necessary
steps to prepare and submit for recordation an Assignment of Mortgage (or a
blanket Assignment of Mortgage covering multiple Mortgage Loans if the same is
permitted in any applicable jurisdiction) at the expense of the Servicer or, if
the Servicer fails to pay such amounts or is no longer a party hereto, pursuant
to Section 8.7(d)(ix) of the Indenture.

                                       5

<PAGE>

      (f)   The Depositor shall sell, assign, transfer, set over and otherwise
convey without recourse to the Indenture Trustee all right, title and interest
of the Depositor in and to any Eligible Substitute Mortgage Loan delivered to
the Indenture Trustee on behalf of the Trust by the Depositor pursuant to
Section 2.03 or Section 2.05 hereof and all its right, title and interest to
principal collected and interest accruing on such Eligible Substitute Mortgage
Loan on and after the applicable Substitute Cut-Off Date; provided, however,
that the Depositor shall reserve and retain all right, title and interest in and
to payments of interest due on such Eligible Substitute Mortgage Loan prior to
the applicable Substitute Cut-Off Date; provided, further, that neither the
Trust nor the Indenture Trustee shall be obligated to fund any future advances
to the related Mortgagor under such Eligible Substitute Mortgage Loan.

      In connection with any transfer and assignment of an Eligible Substitute
Mortgage Loan to the Indenture Trustee on behalf of the Trust, the Depositor
agrees to cause to be delivered to the Custodian on behalf of the Indenture
Trustee the items described in Section 2.01(c) on the date of such transfer and
assignment or, if a later delivery time is permitted by Section 2.01(c), then no
later than such later delivery time.

      (g)   Each Defective Mortgage Loan that is required to be repurchased or
substituted pursuant to the provisions this Agreement or the Purchase Agreement
shall, upon such repurchase or substitution in accordance with the provisions
hereof, be released from the Trust and from the lien created by the Indenture.
As to each Mortgage Loan released from the Trust in connection with the
repurchase thereof or the conveyance of an Eligible Substitute Mortgage Loan
therefor, the Indenture Trustee will transfer, assign, set over and otherwise
convey without recourse, to or upon the order of the Depositor, all of its
right, title and interest in and to such released Mortgage Loan and all the
Trust's right title and interest to principal collected and interest accruing on
such released Mortgage Loan on and after the first day of the calendar month in
which such Mortgage Loan is released; provided, however, that the Trust shall
reserve and retain all right, title and interest in and to payments of principal
and interest collected on such released Mortgage Loan prior to such date.

      Section 2.02. Further Encumbrance of Trust Property.

      (a)   Immediately upon the conveyance to the Trust by the Depositor of any
item of the Trust Property pursuant to Section 2.01, all right, title and
interest of the Depositor in and to such item of Trust Property shall terminate,
and all such right, title and interest shall vest in the Trust, in accordance
with the Trust Agreement and Sections 3802 and 3805 of the Delaware Statutory
Trust Act (12 Del. Code, ss. 3801 et seq.).

      (b)   Immediately upon the vesting of the Trust Property in the Trust, the
Trust shall have the sole right to pledge or otherwise encumber, such Trust
Property. Pursuant to the Indenture and contemporaneously with such property
vesting in the Trust pursuant to (a) above, the Trust shall grant a security
interest in the Trust Property to secure the repayment of the Issuer Secured
Obligations. The Residual Certificates shall represent the beneficial ownership
interest in the Trust Property, and the Residual Certificateholders shall be
entitled to receive distributions with respect thereto as set forth herein.

                                       6

<PAGE>

      (c)   Prior to the payment in full on the Bonds, the payment of all
amounts due to the Insurer under the Insurance Agreement, the termination of the
Policy (as defined therein) and the surrender of the Policy by the Indenture
Trustee to the Insurer, the Indenture Trustee shall hold the Trust Property on
behalf of the Issuer Secured Parties. Following the payment in full of the Bonds
and the payment of all amounts due to the Insurer under the Insurance Agreement,
and the release and discharge of the Indenture, all covenants of the Issuer
under Article III of the Indenture shall, until payment in full of the Residual
Certificates, remain as covenants of the Issuer for the benefit of the Residual
Certificateholders, enforceable by the Residual Certificateholders to the same
extent as such covenants were enforceable by the Insurer and the Bondholders
prior to the discharge of the Indenture. Any rights of the Indenture Trustee
under Article III of the Indenture, following the discharge of the Indenture,
shall vest in the Residual Certificateholders.

      Section 2.03. Acceptance by Indenture Trustee; Certain Substitution of
Mortgage Loans.

      (a)   The Indenture Trustee shall, at such time as there are no Bonds
outstanding and all sums due to (i) the Indenture Trustee or any agent or
counsel thereof pursuant to the Indenture, (ii) the Indenture Trustee pursuant
to this Agreement and (iii) the Insurer pursuant to the Insurance Agreement have
been paid, release any remaining portion of the Trust Property to the Depositor.

      (b)   The Issuer hereby acknowledges its receipt of the Policy and the
Mortgage Loans, and declares that the Indenture Trustee holds and will hold such
instruments, and to the extent that any documents are delivered to it pursuant
to Section 2.01, will hold such documents, and all amounts received by it
thereunder and hereunder, in trust, upon the terms herein set forth, for the use
and benefit of all present and future Bondholders, and the Insurer. If the time
to cure any defect in respect of any Mortgage Loan of which the Indenture
Trustee or the Insurer has notified the Depositor following the review pursuant
to Section 2.01 has expired or if at any time any loss is suffered by the Issuer
or the Indenture Trustee on behalf of the Bondholders or the Insurer, in respect
of any Mortgage Loan as a result of (i) a defect in any document constituting a
part of its Mortgage File or (ii) an Assignment of Mortgage to the Indenture
Trustee not having been recorded as required by Section 2.01, then on the next
succeeding Business Day, the Depositor shall (i) substitute in lieu of such
Mortgage Loan Eligible Substitute Mortgage Loans, and deliver the Substitution
Amount applicable thereto to the Servicer for deposit in the Collection Account
or (ii) purchase such Mortgage Loan at a purchase price equal to the Loan
Purchase Price thereof, which purchase price shall be delivered to the Servicer
for deposit in the Collection Account. Upon receipt of any Mortgage Loan or of
written notification signed by a Servicing Officer to the effect that the Loan
Purchase Price in respect of a Defective Mortgage Loan has been deposited into
the Collection Account, then as promptly as practicable, the Indenture Trustee
shall execute such documents and instruments of transfer presented by the
Depositor, in each case without recourse, representation or warranty, and take
such other actions as shall reasonably be requested by the Depositor to effect
such transfer by the Trust of such Defective Mortgage Loan pursuant to this
Section. It is understood and agreed that the obligation of the Depositor to
accept a transfer of a Defective Mortgage Loan and to either convey an Eligible
Substitute Mortgage Loan or to make a deposit of any related

                                       7

<PAGE>

Loan Purchase Price into the Collection Account shall constitute the sole remedy
respecting such defect available to Bondholders and the Indenture Trustee
against the Depositor.

      (c)   As to any Eligible Substitute Mortgage Loan, the Depositor shall, if
required to deliver any such Eligible Substitute Mortgage Loan, deliver to the
Custodian on behalf of the Indenture Trustee with respect to such Eligible
Substitute Mortgage Loan such documents and agreements as are required to be
held by the Indenture Trustee in accordance with Section 2.01. For any
Collection Period during which the Depositor substitutes one or more Eligible
Substitute Mortgage Loans, the Servicer shall determine the Substitution Amount
which amount shall be deposited by the Depositor in the Collection Account at
the time of substitution. All amounts received in respect of the Eligible
Substitute Mortgage Loan during the Collection Period in which the circumstances
giving rise to such substitution occur shall not be a part of the Trust and
shall not be deposited by the Servicer in the Collection Account. All amounts
received by the Servicer during the Collection Period in which the circumstances
giving rise to such substitution occur in respect of any Defective Mortgage Loan
so removed by the Trust shall be deposited by the Servicer in the Collection
Account. Upon such substitution, the Eligible Substitute Mortgage Loan shall be
subject to the terms of this Agreement in all respects, and the Depositor shall
be deemed (i) to have made with respect to such Eligible Substitute Mortgage
Loan as of the date of substitution, the covenants, representations and
warranties set forth in Section 2.05 and (ii) to have certified that such
Mortgage Loan is an Eligible Substitute Mortgage Loan. The procedures applied by
the Depositor in selecting each Eligible Substitute Mortgage Loan shall not be
materially adverse to the interests of the Indenture Trustee, the Bondholders or
the Insurer.

      The Servicer, promptly following the transfer of a Defective Mortgage Loan
from, or an Eligible Substitute Mortgage Loan to, the Trust pursuant to this
Section, shall amend the Mortgage Loan Schedule and make appropriate entries in
its general account records to reflect such transfer. The Servicer shall,
following such transfer, appropriately mark its records to indicate that it is
no longer servicing such Mortgage Loan on behalf of the Trust. The Depositor,
promptly following such transfer, shall appropriately mark its Electronic Ledger

the Insurer, or a Responsible Officer of the Indenture Trustee that the
substance of such representation and warranty is inaccurate and such inaccuracy
materially and adversely affects the value of the related Mortgage Loan then,
notwithstanding the Depositor's lack of knowledge with respect to the substance
of such representation and warranty being inaccurate at the time the
representation or warranty was made, such inaccuracy shall be deemed a breach of
the applicable representation or warranty. Notwithstanding the foregoing, a
breach of any of the representations and warranties set forth in clauses (lxiii)
through (lxvi) of this Section 2.05 will be deemed to materially and adversely
affect the value of the related Mortgage Loan.

      (b)   It is understood and agreed that the representations and warranties
set forth in this Section 2.05 shall survive delivery of the respective Mortgage
Files to the Indenture Trustee pursuant to Section 2.01 and the termination of
the rights and obligations of the Servicer pursuant to Section 5.04 or 6.02.
Upon discovery by the Depositor, the Servicer, the Insurer or a Responsible
Officer of the Indenture Trustee of a breach of any of the foregoing
representations and warranties, without regard to any limitation set forth
therein concerning the knowledge of the Depositor as to the facts stated
therein, which materially and adversely affects the interests of the Trust or
the Bondholders or the Insurer in the related Mortgage Loans, the party
discovering such breach shall give prompt written notice to the other parties
and to the Insurer. Within 90 days of its discovery or its receipt of notice of
such breach, the Depositor shall use all reasonable efforts to cure such breach
or shall, not later than the Business Day next preceding the Payment Date in the
month following the Collection Period in which any such cure period expired (or
such later date that is acceptable to the Indenture Trustee or the Insurer as
evidenced by their written consents), either (a) repurchase such Mortgage Loan
from the Trust at the Loan Purchase Price or (b) substitute an Eligible
Substitute Mortgage Loan, each in the same manner and subject to the same
conditions as set forth in Section 2.03 and the representations and warranties
set forth in Section 2.04; provided, however, that the cure for any breach of a
representation and warranty relating to the characteristics of the Mortgage
Loans in the aggregate shall be a repurchase of or substitution for only the
Mortgage Loans necessary to cause such characteristics to be in compliance with
the related representation and warranty. Upon accepting such transfer and making
any required deposit into the Collection Account or substitution of an Eligible
Substitute Mortgage Loans, as the case may be, the Depositor shall be entitled
to receive an instrument of assignment or transfer from the Indenture Trustee to
the same extent as set forth in Section 2.03 with respect to the transfer of
Mortgage Loans under that Section. The Insurer shall be notified of any
substitution of an Eligible Substitute Mortgage Loan.

      It is understood and agreed that the obligation of the Depositor to
repurchase a Mortgage Loan as to which a breach has occurred and is continuing
and deposit in the Collection Account the Loan Purchase Price or to substitute
an Eligible Substitute Mortgage Loan, as the case may be, shall constitute the
sole remedy against the Depositor respecting such breach available to
Bondholders, the Indenture Trustee on behalf of Bondholders and the Insurer;
provided, however, that the Depositor shall defend and indemnify the Indenture
Trustee, the Insurer and

                                       23

the Bondholders against all reasonable costs and expenses, and all losses,
damages, claims and liabilities, including reasonable fees and expenses of
counsel and the amount of any settlement entered into with the consent of the
Depositor (such consent not to be unreasonably withheld), which may be asserted
against or incurred by any of them as a result of any third-party action arising
out of any breach of any such representation and warranty. Notwithstanding the
foregoing, with regard to any breach of the representation and warranty set
forth in Section 2.05(a)(xxxi), the Depositor shall pay to the Trust the Loan
Purchase Price.

      The Depositor does hereby assign to the Trust the benefits of the
representations and warranties made to it with respect to the Mortgage Loans
under the Mortgage Loan Purchase Agreement and the Trust may exercise the rights

Insurer of the existence of any Lien on any Mortgage Loans immediately upon
discovery thereof; and the Depositor will defend the Trust's right, title and
interest (including the Trust's security interest) in, to and under the Mortgage
Loans, whether now existing or hereafter created, against all claims of third
parties claiming through or under the Depositor; provided, however, that nothing
in this Section 2.06(a) shall prevent or be deemed to prohibit the Depositor
from suffering to exist upon any of the Mortgage Loans any Liens for municipal
or other local taxes and other governmental charges if such taxes or
governmental charges shall not at the time be due and payable or if the
Depositor shall currently be contesting the validity thereof in good faith by
appropriate proceedings and shall have set aside on its books adequate reserves
with respect thereto.

Mortgage Loans and, to the extent not already included in such filing, on the
applicable Transfer Date with respect to any Eligible Substitute Mortgage Loans,

assign, exchange, pledge, finance, hypothecate, grant a security interest in or
otherwise convey the Residual Certificates except in accordance with Sections
5.04 and 6.02 hereof and in accordance with the Insurance Agreement and the
Trust Agreement.

      (d)   Downgrading. The Depositor will not engage in any activity which
would result in a downgrading or withdrawal of the ratings on the Bonds without
regard to the effect of the Policy.

      (e)   Amendment to Certificate of Formation. The Depositor will not amend
its certificate of formation without prior written notice to the Indenture
Trustee and the Rating

                                       24

Agencies and the prior written consent of the Insurer which consent shall not be
unreasonably withheld.

      (f)   Principal Place of Business. The Depositor's principal place of
business is in California, and the Depositor will not change its principal place
of business without prior written notice to the Indenture Trustee, the Rating
Agencies and the Insurer.

      (g)   No Notification of Mortgagors. The Depositor hereby agrees not to
notify Mortgagors of the transfer of the Mortgage Loans to the Trust unless
required by the terms of the Mortgage Loans or applicable law.

      Section 2.07. Removal of Mortgage Loans at Election of Issuer. Subject to
the conditions set forth below and Section 8.2 of the Indenture, the Issuer may,
but shall not be obligated to, require the removal of Mortgage Loans, from time
to time, as of the close of business on a Payment Date (each, a "Removal Date").
On the tenth Business Day (the "Removal Notice Date") prior to the Removal Date
designated in such notice, the Issuer shall give the Indenture Trustee, the
Insurer and the Servicer a notice of the proposed removal that contains a list
of the Mortgage Loans in the Pool to be removed. Such removal of Mortgage Loans
shall be permitted upon satisfaction of the following conditions:

            (i)       A Rapid Amortization Event shall not have occurred;

            (ii)      On the Removal Date, the Overcollateralization Amount
      (after giving effect to the removal of the Mortgage Loans proposed to be
      removed) equals or exceeds the Specified Overcollateralization Amount;

            (iii)     The transfer of such Mortgage Loans on any Removal Date
      during the Managed Amortization Period shall not, in the reasonable belief
      of the Depositor, cause a Rapid Amortization Event to occur or an event
      which with notice or lapse of time or both would constitute such a Rapid
      Amortization Event and a Rapid Amortization Event has not occurred;

            (iv)      On or before the Removal Date, the Issuer shall have
      delivered to the Indenture Trustee a revised Mortgage Loan Schedule,
      reflecting the proposed transfer and the Removal Date, and the Servicer
      shall have marked the Electronic Ledger to show that the Mortgage Loans
      removed are no longer included in the Pool;

            (v)       The Seller shall represent and warrant that its selection
      procedures are random and no selection procedures reasonably believed by
      the Seller to be adverse to the interests of the Bondholders or the
      Insurer were utilized in selecting the Mortgage Loans to be removed from
      the Pool;

            (vi)      In connection with each such removal of Mortgage Loans
      pursuant to this Section, each Rating Agency shall have received on or
      prior to the related Removal Notice Date notice of such proposed removal
      of Mortgage Loans and, prior to the Removal Date, shall have notified the
      Indenture Trustee and the Insurer in writing that such removal of Mortgage
      Loans would not result in a reduction or withdrawal of its then current
      ratings of the Bonds, without regard to the Policy; and

                                       25

<PAGE>

            (vii)     The Issuer shall have delivered to the Indenture Trustee
      and the Insurer an Officer's Certificate certifying that the items set
      forth in subparagraphs (i) through (vi), inclusive, have been performed or
      are true and correct, as the case may be. The Indenture Trustee and the
      Insurer may conclusively rely on such Officer's Certificate, shall have no
      duty to make inquiries with regard to the matters set forth therein and
      shall incur no liability in so relying.

            (viii)    The Insurer shall have been given an opportunity to review
      any Mortgage Loans proposed to be removed by the Trust.

            (ix)      The Issuer shall have delivered a certificate in the form
      of Exhibit C-1 hereto to the Indenture Trustee.

      Upon receiving the requisite information from the Issuer, the Servicer
shall perform in a timely manner those acts required of it, as specified above.
Upon satisfaction of the above conditions, on the Removal Date the Indenture
Trustee shall deliver, or cause to be delivered, to the Issuer the Mortgage File
for each Mortgage Loan being so transferred, and the Indenture Trustee shall
execute and deliver to the Issuer such other documents prepared by the Issuer as
shall be reasonably necessary to remove such Mortgage Loans from the Pool. Any
such removal of Mortgage Loans shall be without recourse, representation or
warranty by or of the Indenture Trustee or the Trust to the Issuer. The review
right given to the Insurer in clause (viii), above, must be completed prior to
the Removal Date.

      Section 2.08. Execution and Authentication of Bonds. The Indenture
Trustee, on behalf of the Issuer, has caused to be executed, authenticated and
delivered to or upon the order of the Depositor, in exchange for the Issuer,
concurrently with the sale, assignment and conveyance to the Indenture Trustee
of the Issuer, one Class of Bonds in authorized denominations and the Residual
Certificates, evidencing the ownership of the Issuer.

      Section 2.09. Tax Treatment. It is the intention of the Depositor and the
Residual Certificateholders that the Bonds will be indebtedness of the Depositor
for federal, state and local income and franchise tax purposes and for purposes
of any other tax imposed on or measured by income. The Depositor, the Indenture
Trustee and each Bondholder (or Bond Owner) by acceptance of its Bond (or, in
the case of a Bond Owner, by virtue of such Bond Owner's acquisition of a
beneficial interest therein) agrees to treat the Bonds (or beneficial interest
therein), for purposes of federal, state and local income or franchise taxes and
any other tax imposed on or measured by income, as indebtedness of the Depositor
secured by the assets of the Trust and to report the transactions contemplated
by this Agreement on all applicable tax returns in a manner consistent with such
treatment. Each Bondholder agrees that it will cause any Bond Owner acquiring an
interest in a Bond through it to comply with this Agreement as to treatment of
the Bonds as indebtedness for federal, state and local income and franchise tax
purposes and for purposes of any other tax imposed on or measured by income. The
Indenture Trustee will prepare and file all tax reports required hereunder
consistent with this Agreement except as may be required by or provided in
Section 3.15.

      Section 2.10. [Reserved].

                                  ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

      Section 3.01. The Servicer.

      (a)   The Servicer is hereby authorized to act as agent for the Trust and
in such capacity shall manage, service, administer and make collections on the
Mortgage Loans and perform the other actions under this Agreement. The Servicer
shall service and administer the Mortgage Loans in a manner consistent with the
terms of this Agreement and with general industry practice and shall have full
power and authority, acting alone or through a subservicer, to do any and all
things in connection with such servicing and administration which it may deem
necessary or desirable, it being understood, however, that the Servicer shall at
all times remain responsible to the Indenture Trustee, the Bondholders, the
Residual Certificateholders and the Insurer for the performance of its duties
and obligations hereunder in accordance with the terms hereof. Any amounts
received by any subservicer in respect of a Mortgage Loan shall be deemed to
have been received by the Servicer whether or not actually received by it.
Without limiting the generality of the foregoing, the Servicer shall continue,
and is hereby authorized and empowered by the Trust, to execute and deliver, on
behalf of the Trust, any and all instruments of satisfaction or cancellation, or
of partial or full release or discharge and all other comparable instruments,
with respect to the Mortgage Loans and with respect to the Mortgaged Properties
and to make deposits to and withdrawals from the Collection Account. The
Indenture Trustee and the Owner Trustee shall, upon the written request of a
Servicing Officer, furnish the Servicer with any powers of attorney and other
documents necessary or appropriate to enable the Servicer to carry out its
servicing and administrative duties hereunder and consistent with the Indenture
Trustee's internal policies. The Servicer in such capacity may also consent to
the placing of a lien senior to that of any Mortgage on the related Mortgaged
Property, provided that

            (i)       such Mortgage succeeded to a first lien position after the
      related Mortgage Loan was conveyed to the Trust and, immediately following
      the placement of such senior lien, such Mortgage is in a second lien
      position and the outstanding principal amount of the mortgage loan secured
      by such subsequent senior lien is no greater than the outstanding
      principal amount of the senior mortgage loan secured by the Mortgaged
      Property as of the date the related Mortgage Loan was originated; or

            (ii)      the Mortgage relating to such Mortgage Loan was in a
      second lien position as of the Cut-Off Date and the new senior lien
      secures a mortgage loan that refinances an existing first mortgage loan
      and the outstanding principal amount of the replacement first mortgage
      loan immediately following such refinancing is not greater than the
      outstanding principal amount of such existing first mortgage loan at the
      date of origination of such Mortgage Loan;

provided, further, that such senior lien does not secure a note that provides
for negative amortization.

                                       27

<PAGE>

      The Servicer may also, without prior approval from the Rating Agencies or
the Insurer, increase the Credit Limits on HELOC Mortgage Loans provided that
(i) new appraisals are obtained and the Combined Loan-to-Value Ratios of the
HELOC Mortgage Loans after giving effect to such increase are less than or equal
to the Combined Loan-to-Value Ratios of the Mortgage Loans as of the Cut-Off
Date and (ii) such increases are consistent with the Servicer's credit and
collection policies. No material change or departure from the Servicer's credit
and collection policies with respect to any Mortgage Loans as in effect as of
the Closing Date shall be permitted without the prior written consent of the
Insurer.

      In addition, the Servicer may agree to changes in the terms of a Mortgage
Loan at the request of the Mortgagor; provided that (i) such changes do not
materially and adversely affect the interests of Bondholders, the Residual
Certificateholders or the Insurer, (ii) such changes are consistent with prudent
and customary business practice as evidenced by a certificate signed by a
Servicing Officer delivered to the Indenture Trustee and the Insurer and (iii)
the Rating Agencies and the Insurer are promptly notified of the changes.

      In addition to the foregoing, the Servicer may solicit Mortgagors to
change any other terms of the related Mortgage Loans; provided that such changes
(i) do not materially and adversely affect the interest of Bondholders or the
Insurer, (ii) are consistent with prudent and customary business practice as
evidenced by a certificate signed by a Servicing Officer delivered to the
Indenture Trustee and the Insurer and (iii) do not adjust the maturity date of
such Mortgage Loan past the date that is six months before the Final Scheduled
Payment Date of the Bonds. Nothing herein shall limit the right of the Servicer
to solicit Mortgagors with respect to new loans (including mortgage loans) that
are not Mortgage Loans.

      The relationship of the Servicer (and of any successor to the Servicer as
servicer under this Agreement) to the Indenture Trustee under this Agreement is
intended by the parties to be that of an independent contractor and not that of
a joint venturer, partner or agent.

      (b)   In the event that the rights, duties and obligations of the Servicer
are terminated hereunder, any successor to the Servicer in its sole discretion
may, to the extent permitted by applicable law, terminate the existing
subservicer arrangements with any subservicer, without charge, or assume the
terminated Servicer's rights under such subservicing arrangements which
termination or assumption will not violate the terms of such arrangements.

      Section 3.02. Collection of Certain Mortgage Loan Payments.

      (a)   Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Mortgage Loans, and shall, to
the extent such procedures shall be consistent with this Agreement, follow such
collection procedures as it follows with respect to home equity loans in its
servicing portfolio comparable to the Mortgage Loans. Consistent with the
foregoing, and without limiting the generality of the foregoing, the Servicer
may in its discretion (i) waive any late payment charge or any assumption fees
or other fees which may be collected in the ordinary course of servicing such
Mortgage Loans and (ii) arrange with a Mortgagor a schedule for the payment of
interest due and unpaid; provided that such arrangement is consistent with the
Servicer's policies with respect to the Mortgage Loans it owns or services;
provided, further, that notwithstanding such arrangement such Mortgage Loans
will

                                       28

<PAGE>

be included in the information regarding delinquent Mortgage Loans set forth in
the Servicing Certificate and monthly statement to Bondholders pursuant to
Section 4.01.

      (b)   The Servicer shall on the Closing Date deposit into the Collection
Account any amounts representing payments on, and any collections in respect of,
the Mortgage Loans received after the Cut-Off Date and prior to the Closing Date
(exclusive of payments in respect of accrued interest due on or prior to such
Cut-Off Date) and thereafter the Servicer, or the Depositor, as the case may be,
shall deposit into the Collection Account within one Business Day following
receipt thereof the following payments and collections received or made by it
(without duplication):

            (i)       all collections on and in respect of the Mortgage Loans;

            (ii)      the amounts, if any, deposited to the Collection Account
      pursuant to Section 3.04;

            (iii)     Net Liquidation Proceeds;

            (iv)      Insurance Proceeds (including, for this purpose, any
      amount required to be credited by the Servicer pursuant to the last
      sentence of Section 3.04 and excluding the portion thereof, if any, that
      has been applied to the restoration or repair of the related Mortgaged
      Property or released to the related Mortgagor in accordance with the
      normal servicing procedures of the Servicer);

            (v)       any amounts required to be deposited therein pursuant to
      Section 7.01;

            (vi)      any amounts drawn under the Policy pursuant to Section
      8.4(f) of the Indenture, but only to be used for the payment of the items
      specified in Sections 8.7(d)(iii) and (vi) of the Indenture, as
      applicable; and

            (vii)     the amounts, if any, required to be deposited therein by
      the Depositor pursuant to Section 2.05(b) hereof;

provided, however, that with respect to each Collection Period, the Servicer
shall be permitted to retain from payments in respect of interest on the
Mortgage Loans, the Servicing Fee for such Collection Period. The foregoing
requirements respecting deposits to the Collection Account are exclusive, it
being understood that, without limiting the generality of the foregoing, the
Servicer need not deposit in the Collection Account amounts representing
Foreclosure Profits, fees (including annual fees) or late charge penalties
payable by Mortgagors, or amounts received by the Servicer for the accounts of
Mortgagors for application towards the payment of taxes, insurance premiums,
assessments, excess pay off amounts and similar items. The Servicer shall remit
all Foreclosure Profits to the Depositor.

      The Indenture Trustee shall hold amounts deposited in the Collection
Account as Indenture Trustee for the Bondholders and the Insurer. The Servicer
shall notify the Indenture Trustee and the Insurer in writing on each
Determination Date of the amount of payments and

                                       29

<PAGE>

collections in the Collection Account allocable to Interest Collections and
Principal Collections for the related Payment Date. Following such notification,
the Servicer shall be entitled to withdraw from the Collection Account and
retain any amounts that constitute income and gain realized from the investment
of such payments and collections.

      At the written direction of the Servicer, the Indenture Trustee shall
invest funds in the Collection Account in Eligible Investments specified in such
written direction. All income and gain realized from any investment in Eligible
Investments of funds in the Collection Account shall be for the benefit of the
Servicer and shall be subject to its withdrawal from time to time. The amount of
any losses incurred in respect of the principal amount of any such investments
shall be deposited in the Collection Account by the Servicer out of its own
funds immediately as realized. In the absence of written direction the Indenture
Trustee shall invest funds in the Collection Account as directed by the
Depositor.

      Section 3.03. Withdrawals from the Collection Account. From time to time,
withdrawals may be made from the Collection Account by the Servicer or the
Indenture Trustee for the following purposes:

            (i)       If not received by the Servicer pursuant to Section
      3.02(b), to the Servicer as payment for its Servicing Fee pursuant to
      Section 3.08;

            (ii)      To pay to the Servicer amounts on deposit in the
      Collection Account that are not to be included in the distributions and
      payments pursuant to Section 8.7 of the Indenture to the extent provided
      by the second to the last and the last paragraph of Section 3.02(b);

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

            (iv)      Prior to the Collection Period preceding the commencement
      of the Rapid Amortization Period, to pay to the Depositor the amount of
      any Additional Balances related to HELOC Mortgage Loans included in the
      Pool as and when created during the related Collection Period; provided,
      that the aggregate amount so paid to the Depositor in respect of
      Additional Balances with respect to the HELOC Mortgage Loans at any time
      during any Collection Period shall not exceed the amount of Principal
      Collections theretofore received for such Collection Period;

            (v)       To pay to the Servicer any Liquidation Expenses not
      reimbursed prior to the deposit of Net Liquidation Proceeds to the
      Collection Account;

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

      If the Servicer deposits in the Collection 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 it may at any time withdraw such amount from the Collection Account,
and any such amounts shall not be included

                                       30

<PAGE>

in the amounts to be deposited in the Collection Account pursuant to Section
3.02(b), any provision herein to the contrary notwithstanding.

      Section 3.04. Maintenance of Hazard Insurance; Property Protection
Expenses. The Servicer shall cause to be maintained for each Mortgage Loan
hazard insurance naming the Servicer or its successors or assigns as loss payee
thereunder providing extended coverage in an amount which is at least equal to
the lesser of (i) the maximum insurable value of the improvements securing such
Mortgage Loan from time to time or (ii) the combined principal balance owing on
such Mortgage Loan and any mortgage loan senior to such Mortgage Loan from time
to time. The Servicer shall also maintain on property acquired upon foreclosure,
or by deed in lieu of foreclosure, hazard insurance with extended coverage in an
amount which is at least equal to the lesser of (i) the maximum insurable value
from time to time of the improvements which are a part of such property or (ii)
the combined principal balance owing on such Mortgage Loan and any mortgage loan
senior to such Mortgage Loan at the time of such foreclosure or deed in lieu of
foreclosure plus accrued interest and the good-faith estimate of the Servicer of
related Liquidation Expenses to be incurred in connection therewith. Amounts
collected by the Servicer under any such policies shall be deposited in the
Collection Account to the extent called for by Section 3.02. In cases in which
any Mortgaged Property is located in a federally designated flood area, the
hazard insurance to be maintained for the related Mortgage Loan shall include
flood insurance. All such flood insurance shall be in such amounts as are
required under applicable guidelines of the Federal Flood Emergency Act. The
Servicer shall be under no obligation to require that any Mortgagor maintain
earthquake or other additional insurance and shall be under no obligation itself
to maintain any such additional insurance on property acquired in respect of a
Mortgage Loan, other than pursuant to such applicable laws and regulations as
shall at any time be in force and as shall require such additional insurance. If
the Servicer shall obtain and maintain a blanket policy consistent with prudent
industry standards insuring against hazard losses on all of the Mortgage Loans
in an aggregate amount prudent under industry standards, it shall (a)
conclusively be deemed to have satisfied its obligations as set forth in the
first sentence of this Section 3.04 and (b) if there shall have been a loss
which would have been covered by such policy, deposit in the Collection Account
without right of reimbursement, as the case may be, the amount not otherwise
payable under the blanket policy because of any deductible clause.

      Section 3.05. Assumption and Modification Agreements. In any case in which
a Mortgaged Property has been or is about to be conveyed by the Mortgagor, the
Servicer shall exercise its right to accelerate the maturity of such Mortgage
Loan consistent with the then current practice of the Servicer and without
regard to the inclusion of such Mortgage Loan in the Trust. If it elects not to
enforce its right to accelerate or if it is prevented from doing so by
applicable law, the Servicer (so long as such action conforms with the
underwriting standards generally acceptable in the industry at the time for new
origination) is authorized to take or enter into an assumption and modification
agreement from or with the Person to whom such Mortgaged Property has been or is
about to be conveyed, pursuant to which such Person becomes liable under the
Loan Agreement and, to the extent permitted by applicable law, the Mortgagor
remains liable thereon. The Servicer shall notify the Indenture Trustee that any
assumption and modification agreement has been completed by delivering to the
Indenture Trustee an Officer's Certificate signed by a Servicing Officer
certifying that such agreement is in compliance with this Section 3.05 and by
forwarding to the Indenture Trustee the original copy

                                       31

<PAGE>

of such assumption and modification agreement. Any such assumption and
modification agreement shall, for all purposes, be considered a part of the
related Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. No change in the terms of the related Loan
Agreement may be made by the Servicer in connection with any such assumption to
the extent that such change would not be permitted to be made in respect of the
original Loan Agreement pursuant to the fourth paragraph of Section 3.01(a). Any
fee collected by the Servicer for entering into any such agreement will be
retained by the Servicer as additional servicing compensation.

      Section 3.06. Realization Upon Defaulted Mortgage Loans; Repurchase of
Certain Mortgage Loans. The Servicer shall foreclose upon or otherwise
comparably convert to ownership Mortgaged Properties securing such of the
Mortgage Loans as come into and continue in default when, in the opinion of the
Servicer based upon the practices and procedures referred to in the following
sentence, no satisfactory arrangements can be made for collection of delinquent
payments pursuant to Section 3.02; provided, that if the Servicer has knowledge
or reasonably believes that any Mortgaged Property is affected by hazardous or
toxic wastes or substances and that the acquisition of such Mortgaged Property
would not be commercially reasonable, then the Servicer will not cause the Trust
to acquire title to such Mortgaged Property in a foreclosure or similar
proceeding. In connection with such foreclosure or other conversion, the
Servicer shall follow such practices (including, in the case of any default on a
related senior mortgage loan, the advancing of funds to correct such default)
and procedures as it shall deem necessary or advisable and as shall be normal
and usual in its general mortgage servicing activities. The foregoing is subject
to the proviso that the Servicer shall not incur any Liquidation Expenses or
otherwise expend its own funds in connection with any foreclosure or towards the
correction of any default on a related senior mortgage loan or restoration of
any property unless it shall determine that such expenditure will increase Net
Liquidation Proceeds.

      In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure, the deed or certificate of sale
shall be issued to the Indenture Trustee, or to its nominee on behalf of the
Trust.

      Section 3.07. Indenture Trustee to Cooperate. On or before each Payment
Date, the Servicer will notify the Indenture Trustee of the payment in full of
the Principal Balance of any Mortgage Loan during the preceding Collection
Period, which notification shall be by a certification (which certification
shall include a statement to the effect that all amounts received in connection
with such payment which are required to be deposited in the Collection Account
pursuant to Section 3.02 have been so deposited or credited) of a Servicing
Officer. Upon any such payment in full, the Servicer is authorized to execute,
pursuant to the authorization contained in Section 3.01, if the assignments of
Mortgage have been recorded as required hereunder, an instrument of satisfaction
regarding the related Mortgage, which instrument of satisfaction shall be
recorded by the Servicer if required by applicable law and be delivered to the
Person entitled thereto. It is understood and agreed that no expenses incurred
in connection with such instrument of satisfaction or transfer shall be
reimbursed from amounts deposited in the Collection Account. If the Indenture
Trustee is holding the Mortgage Files, from time to time and as appropriate for
the servicing or foreclosure of any Mortgage Loan, or in connection with the
payment in full of the Principal Balance of any Mortgage Loan, the Indenture
Trustee shall, upon request of the Servicer and delivery to the Indenture
Trustee of a Request for Release

                                       32

<PAGE>

substantially in the form attached hereto as Exhibit C signed by a Servicing
Officer, release the related Mortgage File to the Servicer and the Indenture
Trustee shall execute such documents, in the forms provided by the Servicer, as
shall be necessary to the prosecution of any such proceedings or the taking of
other servicing actions. Such trust receipt shall obligate the Servicer to
return the Mortgage File to the Indenture Trustee when the need therefor by the
Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which
case, upon receipt of a certificate of a Servicing Officer similar to that
hereinabove specified, the trust receipt shall be released by the Indenture
Trustee.

      In order to facilitate the foreclosure of the Mortgage securing any
Mortgage Loan that is in default following recordation of the Assignment of
Mortgage in accordance with the provisions hereof, the Indenture Trustee shall,
if so requested in writing by the Servicer, execute an appropriate assignment in
the form provided to the Indenture Trustee by the Servicer to assign such
Mortgage Loan for the purpose of collection to the Servicer or to the related
subservicer (any such assignment shall unambiguously indicate that the
assignment is for the purpose of collection only), and, upon such assignment,
the Servicer will thereupon bring all required actions in its own name and
otherwise enforce the terms of the Mortgage Loan and deposit the Net Liquidation
Proceeds, exclusive of Foreclosure Profits, received with respect thereto in the
Collection Account. In the event that all delinquent payments due under any such
Mortgage Loan are paid by the Mortgagor and any other defaults are cured, then
the Servicer shall, within two Business Days, reassign such Mortgage Loan to the
Indenture Trustee and return the related Mortgage File to the place where it was
being maintained. After such reassignment, the Servicer, if requested by such
Residual Certificateholders and if offered suitable indemnification and
reimbursement for expenses, is authorized to seek a deficiency judgment if
permitted by law against the Mortgagor under such Liquidated Mortgage Loan on
behalf of the Residual Certificateholders to the extent of any losses on
liquidation of any Mortgage Loan.

      Section 3.08. Servicing Compensation; Payment of Certain Expenses by
Servicer. The Servicer shall be entitled to receive the Servicing Fee pursuant
to Section 3.03 as compensation for its services in connection with servicing
the Mortgage Loans. Moreover, additional servicing compensation in the form of
late payment charges or other receipts not required to be deposited in the
Collection Account (other than Foreclosure Profits) shall be retained by the
Servicer. The Servicer shall be required to pay all expenses incurred by it in
connection with its activities hereunder (including payment of all other fees
and expenses not expressly stated hereunder to be for the account of the

      Section 3.10. Annual Servicing Report. On or before ____________ of each
year, beginning ___________, 200_, the Servicer, at its expense, shall cause a
firm of nationally recognized independent public accountants (who may also

Trustee, the Insurer and each Rating Agency to the effect that such firm has
examined certain documents and records relating to the servicing of mortgage
loans during the most recent fiscal year then ended under pooling and servicing
agreements (substantially similar to this Agreement, including this Agreement),
that such examination was conducted substantially in compliance with the audit
guide for audits of non-supervised mortgagees approved by the Department of
Housing and Urban Development for use by independent public accountants (to the
extent that the procedures in such audit guide are applicable to the servicing
obligations set forth in such agreements) and that such examination has
disclosed no items of noncompliance with the provisions of this Agreement which,
in the opinion of such firm, are material, except for such items of

access to the documentation regarding the Mortgage Loans required by applicable
regulations of the Office of Thrift Supervision and the FDIC (acting as operator
of the SAIF or the BIF), such access being afforded without charge but only upon
reasonable request and during normal business hours at the offices of the
Servicer. Nothing in this Section 3.12 shall derogate from the obligation of the
Servicer to observe any applicable law prohibiting disclosure of information
regarding the Mortgagors and the failure of the Servicer to provide access as
provided in this Section 3.12 as a result of such obligation shall not
constitute a breach of this Section 3.12.

      (b)   The Servicer shall supply information in such form as the Indenture
Trustee shall reasonably request to the Indenture Trustee and the Bond Paying
Agent, on or before the start of the Determination Date preceding the related

"Fidelity Bond") and an errors and omissions insurance policy, with broad
coverage with financially responsible companies on all officers, employees, or
other persons acting in any capacity with regard to the Mortgage Loans to handle
funds, money, documents and papers relating to the Mortgage Loans. The Fidelity
Bond and errors and omissions insurance policy shall be in the form of the
Mortgage Banker's Blanket Bond and shall protect and insure the Servicer against
losses, including forgery, theft, embezzlement, fraud, errors and omissions and
negligent acts of such persons. Such Fidelity Bond shall also protect and insure
the Servicer against losses in connection with the failure to maintain any
insurance policies required pursuant to this Agreement and the release or
satisfaction of a Mortgage Loan without having obtained payment in full of the
indebtedness secured thereby. No provision of this Section 3.13 requiring the
Fidelity Bond and errors and omissions insurance policy shall diminish or
relieve the Servicer from its duties and obligations as set forth in this
Agreement. The minimum coverage under any such bond and insurance policy shall
be at least equal to the corresponding amounts required by the Federal Home Loan
Mortgage Corporation in the Federal Home Loan Mortgage Corporation's
Seller/Servicer's Guide. Upon request of the Indenture Trustee or the Insurer,
the Servicer shall cause to be delivered to the Indenture Trustee or the Insurer
a certified true copy of the Fidelity Bond and errors and omissions insurance
policy and a statement from the surety and the insurer that such Fidelity Bond

Trustee and the Insurer.

its control related to this Agreement and the Mortgage Loans as the Manager

tax return for the Trust as well as any other applicable return and apply for a
taxpayer identification number on behalf of the Trust as provided in Article VI
of the Trust Agreement, including, without limitation, forms 1099 and 1065. The
Depositor shall treat the Mortgage Loans as its property for all federal, state
or local tax purposes and shall report all income earned thereon (including
amounts payable as fees to the Servicer) as its income for income tax purposes.
In the event the Trust shall be required pursuant to an audit or administrative
proceeding or change in applicable regulations to file federal, state or local
tax returns, the Servicer shall prepare and file or shall cause to be prepared
and filed any tax returns required to be filed by the Trust; the Indenture
Trustee shall promptly sign such returns and deliver such returns after
signature to the Servicer and such returns shall be filed by the Servicer. The
Indenture Trustee shall also prepare or shall cause to be prepared all tax
information required by law to be distributed to Bondholders. In no event shall
the Indenture Trustee or the Servicer be liable for any liabilities, costs or
expenses of the Trust, the Bondholders, the Residual Certificateholders or the
Bond Owners arising under any tax law, including, without limitation, federal,
state or local income and franchise or excise taxes or any other tax imposed on
or measured by income (or any interest or penalty with respect thereto or

has reason to know that any Mortgaged Property has been abandoned. The reports
from the Servicer shall be in form and substance sufficient to meet the
reporting requirements imposed by Section 6050J.

      Section 3.17. Reporting Requirements. For each Mortgage Loan, the Servicer
will accurately and fully report its borrower credit files to each of Equifax
Credit Information Services, Inc., TransUnion, LLC and Experion Information
Solution, Inc. (or their successors) in a timely manner on a monthly basis.

      Section 3.18. Matters Relating to MERS Loans.

      (a)   The Servicer further is authorized and empowered by the Indenture
Trustee and the Insurer, on behalf of the Bondholders, the Insurer and the
Indenture Trustee, in its own name or in the name of the subservicer, when the
Servicer believes it appropriate in its best judgment to register any Mortgage
Loan on the MERS System, or cause the removal from the registration of any
Mortgage Loan on the MERS System, to execute and deliver, on behalf of the
Indenture

                                       36

Trustee, the Insurer and the Bondholders or any of them, any and all instruments
of assignment and other comparable instruments with respect to such assignment
or re-recording of a Mortgage in the name of MERS, solely as nominee for the
Indenture Trustee and its successors and assigns.

      (b)   In connection with the sale and assignment of any MERS Mortgage Loan
by the Depositor to the Issuer, the Depositor agrees that it will cause, at the
Depositor's expense, the MERS System to indicate that such Mortgage Loans have
been assigned by the Depositor to the Indenture Trustee in accordance with the
Indenture for the benefit of the Issuer Secured Parties by including (or
deleting, in the case of Mortgage Loans which are repurchased in accordance with
this Agreement) in such computer files the information required by the MERS
System to identify the series of the Bonds issued in connection with such
Mortgage Loans. The Depositor further agrees that it will not, and will not
permit the Seller or the Servicer to, and the Seller and the Servicer agree that
they will not, alter the information referenced in this paragraph with respect
to any Mortgage Loan during the term of this Agreement unless and until such
Mortgage Loan is repurchased in accordance with the terms of this Agreement. If
at any time pursuant to Section 2.03, 2.05 or 2.07 the Depositor repurchases a
Mortgage Loan that is a MERS Mortgage Loan, the Servicer shall either (i) cause
MERS to execute and deliver an assignment of the Mortgage in recordable form to
transfer the Mortgage from MERS to the Depositor and shall cause such Mortgage
to be removed from registration on the MERS System in accordance with MERS'
rules and regulations or (ii) cause MERS to designate on the MERS System the
Depositor (or any party indicated by the Depositor) as the beneficial holder of
such Mortgage Loan.

      (c)   In connection with the termination or resignation of the Servicer
hereunder, either (i) the successor Servicer, including the Indenture Trustee if
the Indenture Trustee is acting as successor Servicer, shall represent and
warrant that it is a member of MERS in good standing and shall agree to comply
in all material respects with the rules and procedures of MERS in connection
with the servicing of the Mortgage Loans that are registered with MERS, or (ii)
the predecessor Servicer shall cooperate with the successor Servicer either (x)
in causing MERS to execute and deliver an assignment of Mortgage in recordable
form to transfer the Mortgage from MERS to the Indenture Trustee and to execute
and deliver such other notices, documents and other instruments as may be
necessary or desirable to effect a transfer of such Mortgage Loan or servicing
of such Mortgage Loan on the MERS System to the successor Servicer or (y) in
causing MERS to designate on the MERS System the successor Servicer as the
servicer of such Mortgage Loan.

of, the Servicer or the Depositor. Any entity into which the Servicer or the
Depositor may be merged or consolidated, or any entity resulting from any
merger, conversion or consolidation to which the Servicer or the Depositor shall
be a party, or any entity succeeding to the business of the Servicer or the
Depositor, shall be the successor of the Servicer or the Depositor, as the case
may be, hereunder, without the execution or filing of any paper or any further
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

      Section 5.03. Limitation on Liability of the Servicer and Others. Neither
the Servicer nor any of the directors or officers or employees or agents of the
Servicer shall be under any liability to the Trust or the Bondholders or
Residual Certificateholders for any action taken or for refraining from the
taking of any action by the Servicer in good faith pursuant to this Agreement,
or for errors in judgment; provided, however, that this provision shall not
protect the Servicer or any such Person against any breach of representations
and warranties made herein, or against any specific liability imposed on the
Servicer for a breach of its servicing under this Agreement or against liability
which would otherwise be imposed by reason of willful misfeasance, bad faith or
negligence in the performance of duties of the Servicer or by reason of reckless
disregard of obligations and duties of the Servicer hereunder. The Servicer and
any director or officer or employee or agent of the Servicer may rely in good
faith on any document of any kind prima facie properly executed and submitted by
any Person respecting any matters arising hereunder. The Servicer and any
director or officer or employee or agent of the Servicer shall be indemnified by
the Trust, in accordance with the priorities set forth in Section 8.7(b) of the
Indenture and held harmless against any loss, liability or expense incurred in
connection with any legal action relating to this Agreement or the Bonds, other
than any loss, liability or expense related to any specific Mortgage Loan

pursuant to this Agreement) and any loss, liability or expense incurred by
reason of its willful misfeasance, bad faith or negligence, breach of
representations and warranties made herein, or against any specific liability
imposed on the Servicer for a breach of its servicing under this Agreement or

Agreement, and which in its opinion may

                                       39

<PAGE>

involve it in any expense or liability; provided, however, that the Servicer may
in its sole discretion undertake any such action which it may deem necessary or
desirable in respect of this Agreement, and the rights and duties of the parties
hereto and the interests of the Bondholders and Residual Certificateholders
hereunder. In such event, the reasonable legal expenses and costs of such action
and any liability resulting therefrom shall be expenses, costs and liabilities
of the Trust and the Servicer shall only be entitled to be reimbursed therefor
pursuant to Section 8.7(d)(ix) of the Indenture. The Servicer's right to
indemnity or reimbursement pursuant to this Section 5.03 shall survive any
resignation or termination of the Servicer pursuant to Section 5.04 or 6.01 with
respect to any losses, expenses, costs or liabilities arising prior to such
resignation or termination (or arising from events that occurred prior to such
resignation or termination).

      Section 5.04. Servicer Not to Resign. Subject to the provisions of Section
5.02, the Servicer shall not resign from the obligations and duties hereby
imposed on it except (i) upon determination that the performance of its
obligations or duties hereunder are no longer permissible under applicable law
or are in material conflict by reason of applicable law with any other
activities carried on by it or its subsidiaries or Affiliates, the other
activities of the Servicer so causing such a conflict being of a type and nature
carried on by the Servicer or its subsidiaries or Affiliates at the date of this
Agreement or (ii) upon satisfaction of the following conditions: (a) the
Servicer has proposed a successor servicer to the Indenture Trustee and the
Insurer in writing and such proposed successor servicer is reasonably acceptable
to the Indenture Trustee; (b) each Rating Agency shall have delivered a letter
to the Indenture Trustee and the Insurer prior to the appointment of the
successor servicer stating that the proposed appointment of such successor
servicer as Servicer hereunder will not result in the qualification, reduction
or withdrawal of the then current rating of the Bonds without regard to the
Policy; and (c) such proposed successor servicer is reasonably acceptable to the
Insurer, as evidenced by a letter from each to the Indenture Trustee; provided,
however, that no such resignation by the Servicer shall become effective until
the Indenture Trustee or successor servicer designated by the Servicer as
provided above shall have assumed the Servicer's responsibilities and
obligations hereunder or the Indenture Trustee shall have designated a successor
servicer in accordance with Section 6.02. Any such resignation shall not relieve
the Servicer of responsibility for any of the obligations specified in Sections
6.01 and 6.02 as obligations that survive the resignation or termination of the
Servicer. Any such determination permitting the resignation of the Servicer
pursuant to clause (i) above shall be evidenced by an Opinion of Counsel to such

including any of its Affiliates, or any subservicer referred to in Section 3.01,
who agrees to conduct such duties in accordance with standards comparable to
those with which the Servicer complies pursuant to Section 3.01. Such delegation
shall not relieve the Servicer of its liabilities and responsibilities with
respect to such duties and shall not constitute a resignation within the meaning
of Section 5.04. The Servicer's delegation of any of its duties hereunder to any
subservicer shall be subject to the prior approval of the Insurer. The Servicer
shall terminate its delegation of any of its duties hereunder to any subservicer
at the Insurer's reasonable request.

      Section 5.06. Indemnification of the Trust by the Servicer. The Servicer
shall indemnify and hold harmless the Trust, the Owner Trustee and the Indenture
Trustee from and against any loss, liability, expense, damage or injury suffered
or sustained by reason of the Servicer's activities or omissions in servicing or
administering the Mortgage Loans that are not in accordance with this Agreement
or breach of representations and warranties made herein, including, but not
limited to, any judgment, award, settlement, reasonable attorneys' fees and
expenses and other costs or expenses incurred in connection with the defense of
any actual or threatened action, proceeding or claim. Any such indemnification,
including any amounts the Issuer shall cause the Servicer to pay pursuant to
Section 6.7 of the Indenture, shall not be payable from the assets of the Trust.

injured party subject to the limitations hereof. The provisions of this Section
5.06 shall survive termination of this Agreement.

Notwithstanding anything to the contrary contained herein, the Depositor (i)
agrees to be liable directly to the injured party for the entire amount of any
losses, claims, damages, liabilities and expenses of the Trust (other than those
attributable to a Bondholder as a result of defaults on the Mortgage Loans) to
the extent that the Depositor would be liable if the Trust were a partnership
under the Delaware Revised Uniform Limited Partnership Act in which the
Depositor was a general partner and (ii) shall indemnify and hold harmless the
Trust, the Owner Trustee and the Indenture Trustee from and against any loss,
liability, expense, damage, claim or injury (other than those attributable to a
Bondholder as a result of defaults on the Mortgage Loans) arising out of or
based on this Agreement by reason of any acts, omissions, or alleged acts or
omissions arising out of activities of the Trust, the Owner Trustee or the
Indenture Trustee, or the actions of the Servicer, including, but not limited
to, amounts payable to the Servicer pursuant to Section 5.03, any judgment,
award, settlement, reasonable attorneys' fees and expenses and other costs or
expenses incurred in connection with the defense of any actual or threatened
action, proceeding or claim; provided that the Depositor shall not indemnify the
Owner Trustee or the Indenture Trustee (but shall indemnify any other injured
party) if such loss, liability, expense, damage or injury is due to the Owner
Trustee's or the Indenture Trustee's willful misconduct, bad faith or
negligence, breach of representations and warranties made herein, or against any
specific liability imposed on the Owner Trustee or Indenture Trustee for a
breach of its obligations hereunder. The provisions of this indemnity shall run
directly to and be enforceable by an injured party subject to the limitations
hereof.

      Section 5.08. Limitation on Liability of the Depositor. None of the
directors or officers or employees or agents of the Depositor shall be under any
liability to the Trust, the Owner Trustee or the Indenture Trustee, the
Bondholders or the Residual Certificateholders, it being expressly understood
that all such liability is expressly waived and released as a condition of, and
as consideration for, the execution of this Agreement and the issuance of the
Bonds; provided, however, that this provision shall not protect any such Person
against any liability which would otherwise be imposed by reason of willful
misfeasance, bad faith, negligence or breach of representations and warranties
made herein, or against any specific liability imposed on such Person in the
performance of the duties hereunder. Except as provided in Section 5.07, the
Depositor shall not be under any liability to the Trust, the Owner Trustee or
the Indenture Trustee or the Bondholders or the Residual Certificateholders for
any action taken or for refraining from the taking of any action in its capacity
as Depositor pursuant to this Agreement

                                       41

<PAGE>

whether arising from express or implied duties under this Agreement; provided,
however, that this provision shall not protect the Depositor against any
liability which would otherwise be imposed by reason of willful misconduct, bad
faith or negligence in the performance of its duties or by reason of reckless
disregard of its obligations and duties hereunder. The Depositor and any
director or officer or employee or agent of the Depositor may rely in good faith
on any document of any kind prima facie properly executed and submitted by any
Person respecting any matters arising hereunder.

      principal amount of at least $1,000,000 when due, subject to the
      applicable grace period, if any, specified in the agreement or other
      instrument relating to such debt and shall continue after the applicable
      grace period if the effect of such event is to accelerate the maturity and
      repayment of such debt before the stated maturity thereof;

            (xi)      Redwood Trust, Inc. shall no longer own 100% of the Issuer
      either directly or indirectly;

then, and in each and every such case, so long as an Event of Servicing
Termination shall not have been remedied by the Servicer, either the Indenture
Trustee, the Insurer or the Holders of Bonds evidencing more than 50% of the
Outstanding Amount of the Bonds, in each case with the consent of the Insurer,
by notice then given in writing to the Servicer (and to the Indenture Trustee if
given by the Insurer or the Holders of Bonds) may terminate all of the rights
and obligations of the Servicer as servicer under this Agreement. Any such
notice to the Servicer

                                       43

<PAGE>

shall also be given to each Rating Agency and the Insurer. On or after the
receipt by the Servicer of such written notice, all authority and power of the
Servicer under this Agreement, whether with respect to the Bonds or the Mortgage
Loans or otherwise, shall pass to and be vested in the Indenture Trustee
pursuant to and under this Section 6.01; and, without limitation, the Indenture
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
the Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and related
documents, or otherwise. The Servicer agrees to cooperate with the Indenture
Trustee in effecting the termination of the responsibilities and rights of the
Servicer hereunder, including, without limitation, the transfer to the Indenture
Trustee for the administration by it of all cash amounts that shall at the time
be held by the Servicer to be deposited by it in the Collection Account, or that
have been deposited by the Servicer in the Collection Account or thereafter
received by the Servicer with respect to the Mortgage Loans. All reasonable
costs and expenses (including attorneys' fees and expenses) incurred in
connection with amending this Agreement to reflect such succession as Servicer
pursuant to this Section 6.01 shall be paid by the predecessor Servicer (or if
the predecessor Servicer is the Indenture Trustee, the initial Servicer) upon
presentation of reasonable documentation of such costs and expenses.

      Notwithstanding the foregoing, a delay in or failure of performance under
Section 6.01(i) for a period of one Business Day or under Section 6.01(ii) for a
period of 15 days, shall not constitute an Event of Servicing Termination if
such delay or failure could not be prevented by the exercise of reasonable
diligence by the Servicer and such delay or failure was caused by an act of God
or the public enemy, acts of declared or undeclared war, public disorder,
rebellion or sabotage, epidemics, landslides, lightning, fire, hurricanes,
earthquakes or floods. The preceding sentence shall not relieve the Servicer
from using its best efforts to perform its respective obligations in a timely
manner in accordance with the terms of this Agreement and the Servicer shall
provide the Indenture Trustee, the Depositor, the Insurer and the Bondholders
and Residual Certificateholders with an Officer's Certificate giving prompt
notice of such failure or delay by it, together with a description of its
efforts to so perform its obligations. The Servicer shall immediately notify the
Indenture Trustee and the Insurer in writing of any Events of Servicing
Termination.

      Section 6.02. Indenture Trustee to Act; Appointment of Successor.

      (a)   On and after the time the Servicer receives a notice of termination
pursuant to Section 6.01 or resigns pursuant to Section 5.04, the Indenture
Trustee shall be the successor in all respects to the Servicer in its capacity
as servicer under this Agreement and the transactions set forth or provided for
herein and shall be subject to all the responsibilities, duties and liabilities
relating thereto placed on the Servicer by the terms and provisions hereof.
Notwithstanding the above, if the Indenture Trustee becomes the Servicer
hereunder, it shall have no responsibility or obligation (i) of repurchase or
substitution with respect to any Mortgage Loan, (ii) with respect to any
representation or warranty of the Servicer, and (iii) for any act or omission of
either a predecessor or successor Servicer other than the Indenture Trustee. As
compensation therefor, the Indenture Trustee shall be entitled to such
compensation as the Servicer would have been entitled to hereunder if no such
notice of termination had been given. In addition, the Indenture Trustee will be
entitled to compensation with respect to its

                                       44

<PAGE>

expenses in connection with conversion of certain information, documents and
record keeping, as provided in Sections 6.7 and 6.8 of the Indenture.
Notwithstanding the above, (i) if the Indenture Trustee is unwilling to act as
successor Servicer, or (ii) if the Insurer is unwilling to have the Indenture
Trustee act as successor Servicer or (iii) if the Indenture Trustee is legally
unable so to act, the Indenture Trustee may with the consent of the Insurer (in
the situation described in clauses (i) or (ii)) or shall (in the situation
described in clause (iii)) appoint or petition a court of competent jurisdiction
to appoint, any established housing and home finance institution, bank or other
mortgage loan or home equity loan servicer with all licenses and permits
required to perform its obligations under this Agreement and having a net worth
of not less than $15,000,000 as the successor to the Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Servicer hereunder; provided that any such successor Servicer shall be
acceptable to the Insurer, as evidenced by its prior written consent, which
consent shall not be unreasonably withheld; and provided, further, that the
appointment of any such successor Servicer will not result in the qualification,
reduction or withdrawal of the ratings assigned to the Bonds by the Rating
Agencies without regard to the Policy. Pending appointment of a successor to the
Servicer hereunder, unless the Indenture Trustee is prohibited by law from so
acting, the Indenture Trustee shall act in such capacity as hereinabove
provided. In connection with such appointment and assumption, the successor
shall be entitled to receive compensation out of payments on Mortgage Loans in
an amount equal to the compensation which the Servicer would otherwise have
received pursuant to Section 3.08 (or such lesser compensation as the Indenture
Trustee and such successor shall agree). The Indenture Trustee and such
successor shall take such action, consistent with this Agreement, as shall be
necessary to effectuate any such succession.

      (b)   Any successor, including the Indenture Trustee, to the Servicer as
servicer shall during the term of its service as servicer (i) continue to
service and administer the Mortgage Loans for the benefit of the Bondholders,
Residual Certificateholders and the Insurer and (ii) maintain in force a policy
or policies of insurance covering errors and omissions in the performance of its
obligations as Servicer hereunder and a fidelity bond in respect of its
officers, employees and agents to the same extent as the Servicer is so required
pursuant to Section 3.13. The appointment of a successor Servicer shall not
affect any liability of the predecessor Servicer which may have arisen under
this Agreement prior to its termination as Servicer (including, without
limitation, any deductible under an Insurance Policy pursuant to Section 3.04),
nor shall any successor Servicer be liable for any acts or omissions of the
predecessor Servicer or for any breach by such Servicer of any of its
representations or warranties contained herein.

      Section 6.03. Notification to Bondholders and Residual Certificateholders.
Upon any termination or appointment of a successor to the Servicer pursuant to
this Article VI or Section 5.04, the Indenture Trustee shall give prompt written
notice thereof to the Bondholders, Residual Certificateholders (at their
respective addresses appearing in the Bond Register and in the Residual
Certificate Register), the Insurer and each Rating Agency.

                                  TERMINATION

      Section 7.01. Termination.

      (a)   The respective obligations and responsibilities of the Servicer, the
Depositor and the Indenture Trustee created hereby (other than the obligation of
the Indenture Trustee to make certain payments to Bondholders after the final
Payment Date and the obligation of the Servicer to send certain notices as
hereinafter set forth) shall terminate upon the last action required to be taken
by the Indenture Trustee on the final Payment Date pursuant to this Article VII
following the later of (A) the Payment Date following payment in full of all
amounts owing to the Insurer under the Insurance Agreement and (B) the earliest
of (i) the transfer, under the conditions specified in Section 7.01(b), to the
Depositor of the Bondholders' interest in each remaining Mortgage Loan and all
property acquired in respect of any remaining Mortgage Loans, (ii) the day
following the Payment Date on which the distribution made to Bondholders has
reduced the Bond Principal Balance to zero and no other amounts are owed to the
Bondholders hereunder, and no other amounts are owed to the Insurer pursuant to
the Insurance Agreement and Section 8.7 of the Indenture, (iii) the final
payment or other liquidation of the last Mortgage Loan remaining in the Trust
(including, without limitation, the disposition of the Mortgage Loans pursuant
to Section 5.4 of the Indenture) or the disposition of all property acquired
upon foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (iv)
the Payment Date in _____ 20__; provided, however, that in no event shall the
trust created hereby continue beyond the expiration of 21 years from the date of
death of the last surviving descendants of Joseph P. Kennedy, the late
ambassador of the United States to the Court of St. James, living on the date
hereof. Upon termination in accordance with clause (a)(B)(i) of this Section
7.01, the Indenture Trustee shall execute such documents and instruments of
transfer presented by the Depositor, in each case without recourse,
representation or warranty, and take such other actions as the Depositor may
reasonably request to effect the transfer of the Mortgage Loans to the
Depositor.

      (b)   Subject to Section 7.01(d), the Depositor shall have the right to
effect the transfer to the Depositor of each Mortgage Loan on any Payment Date
on or after the Payment Date immediately prior to which the Pool Balance is less
than or equal to ten percent (10%) of the Initial Pool Balance. If the Depositor
elects to exercise its right it will notify the Issuer, the Servicer, the
Indenture Trustee and the Insurer no later than thirty-five (35) days prior to
the Payment Date on which the transfer is to take place. The Indenture Trustee
will make the transfer on such Payment Date subject to Section 7.01(d) and
provided that the Redemption Price for the Bonds has been deposited with it not
less than five (5) Business Days prior to such Payment Date.

      (c)   The Depositor, at its expense, shall prepare and deliver to the
Indenture Trustee for execution, at the time the related Mortgage Loans are to
be released to the Depositor, appropriate documents assigning each such Mortgage
Loan from the Indenture Trustee to the Depositor and shall promptly record such
assignments.

      (d)   The Depositor shall not exercise its right to repurchase the
Mortgage Loans pursuant to Section 7.01(b) hereof if (a) such repurchase would
result in a draw on the Policy,

                                       46

<PAGE>

without the consent of the Insurer, and (b) any Reimbursement Amount due to the
Insurer would not be fully satisfied pursuant to the repurchase.

      in connection with the resignation or removal of the Owner Trustee, and

      opinion, no less favorable to the Issuer in any material respect.

      (c)   Non-Ministerial Matters. With respect to matters that in the
reasonable judgment of the Servicer are non-ministerial, the Servicer shall not
take any action pursuant to this Article VIII unless within a reasonable time
before the taking of such action, the Servicer shall have notified the Owner

                            MISCELLANEOUS PROVISIONS

      Section 9.01. Amendment. This Agreement may be amended from time to time
by agreement among the Depositor, the Servicer, and the Indenture Trustee, in
each case without notice to or the consent of any of the Bondholders or Residual
Certificateholders, but only with the consent of the Insurer (which consent
shall not be unreasonably withheld), (i) to cure any ambiguity, (ii) to correct
any defective provisions or to correct or supplement any provisions herein that
may be inconsistent with any other provisions herein, (iii) to add to the duties
of the Depositor or the Servicer, (iv) to add any other provisions with respect
to matters or questions arising under this Agreement or the Policy, as the case
may be, which shall not be inconsistent with the provisions of this Agreement,
(v) to add or amend any provisions of this Agreement as required by any Rating
Agency or any other nationally recognized statistical rating organization in
order to maintain or improve any rating of the Bonds (it being understood that,
after obtaining the ratings in effect on the Closing Date, neither the Indenture
Trustee, the Depositor nor the Servicer is obligated to obtain, maintain or
improve any such rating) or (vi) to comply with any requirement imposed by the
Code; provided, however, that such action shall not, as evidenced by an Opinion
of Counsel, materially and adversely affect the interests of any Bondholder, any
Residual Certificateholder, or the Insurer; and provided, further, that the
amendment shall be deemed not to adversely affect in any material respect the
interests of the Bondholders and the Residual Certificateholders and no opinion
referred to in the preceding proviso shall be required to be delivered if the
Person requesting the amendment obtains a letter from each Rating Agency stating
that the amendment would not result in the downgrading or withdrawal of the
respective ratings then assigned to the Bonds without regard to the Policy.

      This Agreement also may be amended from time to time by agreement among
the Servicer, the Depositor and the Indenture Trustee, with the consent of the
Insurer and the Holders of the Bonds evidencing more than 50% of the Outstanding
Amount of the Bonds and the Holders of the Residual Certificates evidencing more
than 50% of the percentage interest in the Residual Certificates (which consent
of such Holders of Bonds and Residual Certificates given pursuant to this
Section 9.01 or pursuant to any other provision of this Agreement shall be
conclusive and binding on such Holder and all future Holders of such securities
and of any security issued upon the transfer thereof or in exchange thereof or
in lieu thereof whether or not

                                       49

<PAGE>

notation of such consent is made upon the security) for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement or of modifying in any manner the rights of the Bondholders or
the Residual Certificateholders; provided, however, that no such amendment shall
(i) reduce in any manner the amount of, or delay the timing of, payments on the
Bonds or distributions or payments under the Policy which are required to be
made on any Bond without the consent of the Holder of such Bond or (ii) reduce
the aforesaid percentage required to consent to any such amendment, without the
consent of the Holders of all then outstanding Bonds and Residual Certificates
or (iii) adversely affect in any material respect the interests of the Insurer.

      Following the execution and delivery of any such amendment hereto or to
the Policy, either the Depositor, if the Depositor requested the amendment, or
the Servicer, if the Servicer requested the amendment, shall reimburse the
Insurer for the reasonable out-of-pocket costs and expenses incurred by each in
connection with such amendment.

      Prior to the execution of any such amendment, the party hereto requesting
any such amendment shall furnish written notification of the substance of such
amendment to each Rating Agency. In addition, promptly after the execution of
any such amendment made with the consent of the Bondholders or the Residual
Certificateholders, the Indenture Trustee shall furnish written notification of
the substance of such amendment to each Bondholder and Residual
Certificateholder and fully executed original counterparts of the instruments
effecting such amendment to the Insurer.

      It shall not be necessary for the consent of Bondholders or Residual
Certificateholders under this Section 9.01 to approve the particular form of any
proposed amendment or consent, but it shall be sufficient if such consent shall
approve the substance thereof. The manner of obtaining such consents and of
evidencing the authorization of the execution thereof by Bondholders and
Residual Certificateholders shall be subject to such reasonable requirements as
the Indenture Trustee may prescribe.

      In executing any amendment permitted by this Section 9.01, the Indenture
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Opinion of Counsel stating that such amendment is authorized or
permitted hereby and that all conditions precedent to the execution and delivery
of such amendment have been satisfied. The Indenture Trustee may, but shall not
be obligated to, enter into any such amendment which affects the Indenture

members of an association; nor shall any Bondholder be under any liability to
any third person by reason of any action taken by the parties to this Agreement
pursuant to any provision hereof.

      No Bondholder shall have any right by virtue or by availing itself of any

receipt of such notice, request and offer of indemnity, shall have neglected or
refused to institute any such action, suit or proceeding; it being understood
and intended, and being expressly covenanted by each Bondholder with every other
Bondholder and the Indenture Trustee, that no one or more Holders of Bonds shall
have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice

obtain priority over or preference to any other such Holder, or to enforce any
right under this Agreement, except in the manner herein provided and for the
equal, ratable and common benefit of all Bondholders. For the protection and
enforcement of the provisions of this Section 9.03, each and every Bondholder
and the Indenture Trustee shall be entitled to such relief as can be given
either at law or in equity.

      Anything to the contrary notwithstanding, by accepting its Bond, each

the right to exercise all rights of the Bondholder under this Agreement without
any further consent of the Bondholder.
