                           Original Issuance of Notes

         Section 2.01. FORM. The Notes, together with the Indenture Trustee's
certificate of authentication, shall be in substantially the forms set forth in
Exhibits A-1 through A-3, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture.

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

         The terms of the Notes set forth in Exhibits A-1 through A-3 are part
of the terms of this Indenture.

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

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

         The Indenture Trustee shall upon Issuer Request authenticate and
deliver Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class M-1, Class
M-2 and Class B-1 Notes for original issue. The Notes shall be issued in an
aggregate initial principal amount of $292,395,000.00.

         Each Class of Notes shall be dated the date of its authentication. The
Class A Notes and Class M-1 Notes shall be issuable as registered Notes and
shall be issuable in the minimum initial Note Principal Balances of $25,000 and
in integral multiples of $1 in excess thereof. The Class M-2 Notes and Class B-1
Notes shall be issuable as registered Notes and shall be issuable in the minimum
initial Note Principal Balances of $250,000 and in integral multiples of $1 in
excess thereof.

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

         Section 2.03. ACCEPTANCE OF MORTGAGE LOANS BY INDENTURE TRUSTEE. (a)
The Indenture Trustee acknowledges receipt of, subject to the exceptions it
notes pursuant to the procedures described below, the documents (or certified
copies thereof) referred to in Section 2.1(b) of the Mortgage Loan Purchase
Agreement and declares that it holds and will continue to hold those

                                        4





documents and any amendments, replacements or supplements thereto and all other
assets of the Trust Estate as Indenture Trustee in trust for the use and benefit
of all present and future Holders of the Notes. No later than 45 days after the
Closing Date and each Subsequent Transfer Date (or, with respect to any Eligible
Substitute Mortgage Loan, within 5 days after the receipt by the Indenture
Trustee thereof and, with respect to any documents received beyond 45 days after
the Closing Date, promptly thereafter), the Indenture Trustee agrees, for the
benefit of the Noteholders, to review each Mortgage File delivered to it and to
execute and deliver, or cause to be executed and delivered, to the Seller and
the Master Servicer an Initial Certification in the form annexed hereto as
Exhibit B. In conducting such review, the Indenture Trustee will ascertain
whether all required documents described in Section 2.1(b) of the Mortgage Loan
Purchase Agreement have been executed and received and whether those documents
relate, determined on the basis of the Mortgagor name, original principal
balance and loan number, to the Mortgage Loans it has received, as identified in
Exhibit D to this Indenture, as supplemented (PROVIDED, HOWEVER, that with
respect to those documents described in subclause (b)(vii) of such section, the
Indenture Trustee's obligations shall extend only to documents actually
delivered pursuant to such subclause). In performing any such review, the
Indenture Trustee may conclusively rely on the purported due execution and
genuineness of any such document and on the purported genuineness of any
signature thereon. If the Indenture Trustee finds any document constituting part
of the Mortgage File not to have been executed or received, or to be unrelated
to the Mortgage Loans identified in Exhibit D or to appear to be defective on
its face, the Indenture Trustee shall promptly notify the Seller of such finding
and the Seller's obligation to cure such defect or repurchase or substitute for
the related Mortgage Loan.

         (b) No later than 180 days after the Closing Date, the Indenture
Trustee will review, for the benefit of the Noteholders, the Mortgage Files and
will execute and deliver or cause to be executed and delivered to the Seller, a
Final Certification in the form annexed hereto as Exhibit C. In conducting such
review, the Indenture Trustee will ascertain whether an original of each
document described in subclauses (b)(ii)-(iv) of Section 2.1 of the Mortgage
Loan Purchase Agreement required to be recorded has been returned from the
recording office with evidence of recording thereon or a certified copy has been
obtained from the recording office. If the Indenture Trustee finds any document
constituting part of the Mortgage File has not been received, or to be
unrelated, determined on the basis of the Mortgagor name, original principal
balance and loan number, to the Mortgage Loans identified in Exhibit D or to
appear defective on its face, the Indenture Trustee shall promptly notify the
Seller and the Indenture Trustee shall enforce its rights against the Seller
with respect thereto as provided in Section 2.1 of the Mortgage Loan Purchase
Agreement.

         (c) In the event of a repurchase of the related Mortgage Loan, upon
deposit of the Repurchase Price in the Payment Account, or in the event of a
substitution, upon deposit of the Substitution Adjustment Amount (or if none,
then within one Business Day of when the Mortgage File for the Eligible
Substitute Mortgage Loan is received), the Indenture Trustee shall release to
the Seller the related Mortgage File and shall execute and deliver all
instruments of transfer or assignment, without recourse, furnished to it by the
Seller as are necessary to vest in the Seller title to and rights under the
related Mortgage Loan. Such purchase shall be deemed to have occurred on the
date on which certification of the deposit of the Repurchase Price (or the

                                        5





Substitution Adjustment Amount, if any) in the Payment Account was received by
the Indenture Trustee, or if no such amount was received, within one Business
Day of when the Mortgage File for the Eligible Substitute Mortgage Loan is
received. The Indenture Trustee shall amend the applicable Mortgage Loan
Schedule to reflect such repurchase or substitution and shall promptly notify
the Master Servicer and the Rating Agencies of such amendment.

                                    Covenants

         Section 3.01. COLLECTION OF PAYMENTS WITH RESPECT TO THE MORTGAGE
LOANS. The Indenture Trustee shall establish and maintain an Eligible Account
(the "Payment Account") in which the Indenture Trustee shall, subject to the
terms of this paragraph, deposit, (i) on the same day as it is received from the
Master Servicer, each remittance received by the Indenture Trustee with respect
to the Mortgage Loans and (ii) all amounts transferred from the Pre-Funding
Account and the Interest Coverage Account. The Indenture Trustee shall make all
payments of principal of and interest on the Notes, subject to Section 3.03 as
provided in Section 3.05 herein from monies on deposit in the Payment Account.

         Section 3.02. MAINTENANCE OF OFFICE OR AGENCY. The Issuer will maintain
in the Borough of Manhattan, The City of New York, an office or agency where,
subject to satisfaction of conditions set forth herein, Notes may be surrendered
for registration of transfer or exchange, and where notices and demands to or
upon the Issuer in respect of the Notes and this Indenture may be served. The
Issuer hereby initially appoints the Indenture Trustee to serve as its agent for
the foregoing purposes. If at any time the Issuer shall fail to maintain any
such office or agency or shall fail to furnish the Indenture Trustee with the
address thereof, such surrenders, notices and demands may be made or served at
the Corporate Trust Office, and the Issuer hereby appoints the Indenture Trustee
as its agent to receive all such surrenders, notices and demands.

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

         The Issuer hereby designates the Indenture Trustee as Paying Agent,
which initially shall be Bankers Trust of California, N.A.

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

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


                                        7





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

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

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

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

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

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

         Subject to applicable laws with respect to escheat of funds, any money
held by the Indenture Trustee or any Paying Agent in trust for the payment of
any amount due with respect to any Note and remaining unclaimed for one year
after such amount has become due and payable shall be discharged from such trust
and be paid to the Issuer on Issuer Request; and the Holder of such Note shall
thereafter, as an unsecured general creditor, look only to the Issuer for
payment thereof (but only to the extent of the amounts so paid to the Issuer),
and all liability of the Inden ture Trustee or such Paying Agent with respect to
such trust money shall thereupon cease; provided, however, that the Indenture
Trustee or such Paying Agent, before being required to make any such repayment,
shall at the expense and direction of the Issuer cause to be published once, in
an Authorized Newspaper published in the English language, notice that such
money remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication, any unclaimed
balance of such money then remaining will be repaid to the Issuer. The Indenture
Trustee may also adopt and employ, at the expense and direction of the Issuer,
any other reasonable means of notification of such repayment (including, but not
limited to, mailing notice of such repayment to Holders whose Notes have been
called but have not been surrendered for redemption or whose right to or
interest in monies due and payable but not claimed is determinable from the
records of the Indenture Trustee or of any Paying Agent, at the last address of
record for each such Holder).

                                        8





         Section 3.04. EXISTENCE. The Issuer will keep in full effect its
existence, rights and franchises as a business 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 Notes, the Mortgage Loans and each other
instrument or agreement included in the Trust Estate.

         Section 3.05. PAYMENT OF PRINCIPAL AND INTEREST. (a) On each Payment
Date from amounts on deposit in the Payment Account in accordance with Section
8.02 hereof, the Indenture Trustee shall pay to the Noteholders, and to other
Persons the Interest Remittance Amount and Principal Distribution Amount.

         (b) On each Payment Date, the Interest Remittance Amount shall be
distributed in the following priority, in each case to the extent of the then
remaining Interest Remittance
Amount:

                           (i) to the Class A Noteholders, on a pro rata basis,
         Accrued Note Interest thereon for such Payment Date, plus any Unpaid
         Interest Shortfalls thereon remaining unpaid from any previous Payment
         Date; provided, however, that if on any Payment Date the Interest
         Remittance Amount is less than the aggregate Accrued Note Interest on
         the Class A Notes, the amount payable to the Class A Noteholders
         pursuant to this clause (i) shall be reduced on a pro rata basis among
         the Class A Notes based upon the Accrued Note Interest payable thereon;

                           (ii) to the Class M-1 Noteholders, Accrued Note
         Interest thereon for such Payment Date;

                           (iii) to the Class M-2 Noteholders, Accrued Note
         Interest thereon for such Payment Date;

                           (iv) to the Class B-1 Noteholders, Accrued Note
         Interest thereon for such Payment Date;

                           (v) to the Class M-1 Noteholders, any Unpaid Interest
         Shortfalls thereon remaining unpaid from any previous Payment Date;

                           (vi) to the Class M-2 Noteholders, any Unpaid
         Interest Shortfalls thereon remaining unpaid from any previous Payment
         Date;

                           (vii) to the Class B-1 Noteholders, any Unpaid
         Interest Shortfalls thereon remaining unpaid from any previous Payment
         Date;

                           (viii) to the Certificate Paying Agent on behalf of
         the Class B-2 Certificateholders, Accrued Certificate Interest thereon
         for such Payment Date; provided,

                                        9





         however, that on any Payment Date on which the Certificate Principal
         Balance of the Class B-2 Certificates is reduced to zero due to
         Realized Losses, in the event the Note Principal Balance of the Class
         B-1 Notes would also be reduced on such Payment Date as a result of the
         allocation of Realized Losses, the amount payable to the Class B-2
         Certificates pursuant to this clause will be reduced by the amount
         which the Class B-1 Notes would have had its Note Principal Balance
         reduced; and

                  (ix) any amount remaining (such amount, the "Net Monthly
Excess Interest Amount") for such Payment Date shall be included in the Net
Monthly Excess Cash Flow and be
distributed as provided in 3.05(e).

         (c) On each Payment Date prior to the Stepdown Date, the Principal
Distribution Amount shall be distributed in the following priority, in each case
to the extent of the then remaining Principal Distribution Amount:

                           (i) first, to the Class A Noteholders, in the
         priorities set forth in Sections 3.05(f) and (g), until the aggregate

         an amount equal to the lesser of (a) the Principal Distribution Amount
         for such Payment Date and (b) the aggregate Note Principal Balance of
         the Class A Notes immediately prior to such Payment Date;

                           (ii) second, to the Class M-1 Notes, until the Note

         Principal Balances of the Class A Notes have been reduced to an amount
         equal to (x) the aggregate Principal Balance of the Mortgage

         the Principal Distribution Amount after the distribution described in
         clause (i) above, to the Class M-1 Notes, until the sum of the Note
         Principal Balance of the Class A Notes and the Class M-1 Notes has been
         reduced to an amount equal to (x) the aggregate Principal Balance of
         the Mortgage Loans as of the last day of the related Due Period minus
         (y) the greater of (a) 37.37% of the aggregate Principal Balance of the
         Mortgage Loans as of the last day of the related Due Period plus the

from, and votes of, the Depository as Holder of the Notes shall not be deemed
inconsistent if they are made with respect to different Beneficial Owners. The
Indenture Trustee may establish a reasonable record date in connection with
solicitations of consents from or voting by Noteholders and give notice to the
Depository of such record date. Without the consent of the Issuer and the
Indenture Trustee, no Note may be transferred by the Depository except to a
successor Depository that agrees to hold such Class A Note for the account of
the Beneficial Owners.

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

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

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

         Subject to the restrictions and limitations set forth below, upon
surrender for registration of transfer of any Note at the Corporate Trust
Office, the Issuer shall execute and the Note

                                       22





Registrar shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Notes in authorized initial Note
Principal Balances evidencing the same aggregate Percentage Interests.

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

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

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

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

                                       23





replacement Note was delivered or any assignee of such Person, except a bona
fide purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
the Issuer or the Indenture Trustee in connection
therewith.

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

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

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

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

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

         Section 4.06. BOOK-ENTRY NOTES. The Notes, upon original issuance, will
be issued in the form of typewritten Notes representing the Book-Entry Notes, to
be delivered to The Depository Trust Company, the initial Depository, by, or on
behalf of, the Issuer. Such Notes shall initially be registered on the Note
Register in the name of Cede & Co., the nominee of the initial

                                       24





Depository, and no Beneficial Owner will receive a Definitive Note representing
such Beneficial Owner's interest in such Note, except as provided in Section
4.08. With respect to such Notes, unless and until definitive, fully registered
Notes (the "Definitive Notes") have been issued to Beneficial Owners pursuant to
Section 4.08:

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

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

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

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

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

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

         Section 4.08. DEFINITIVE NOTES. If (i) the Indenture Trustee determines
that the Depository is no longer willing or able to properly discharge its
responsibilities with respect to the Notes and the Indenture Trustee is unable
to locate a qualified successor, (ii) the Indenture Trustee elects to terminate
the book-entry system through the Depository or (iii) after the occurrence of an
Event of Default, Beneficial Owners of Notes representing beneficial interests
aggregating at least a majority of the Note Principal Balances of the Notes
advise the Depository in writing that the continuation of a book-entry system
through the Depository is no longer in the best interests of the Beneficial
Owners, then the Depository shall notify all Beneficial Owners and the Indenture
Trustee of the occurrence of any such event and of the availability of
Definitive Notes to Beneficial

                                       25





Owners requesting the same. Upon surrender to the Indenture Trustee of the
typewritten Notes representing the Book-Entry Notes by the Depository,
accompanied by registration instructions, the Issuer shall execute and the
Indenture Trustee shall authenticate the Definitive Notes in accordance with the
instructions of the Depository. None of the Issuer, the Note Registrar or the
Indenture Trustee shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Notes, the Indenture Trustee shall
recognize the Holders of the Definitive Notes as Noteholders.

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

         Section 4.10. SATISFACTION AND DISCHARGE OF INDENTURE. This Indenture
shall cease to be of further effect with respect to the Notes except as to (i)
rights of registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Notes, (iii) rights of Noteholders to receive payments
of principal thereof and interest thereon, (iv) Sections 3.03, 3.04, 3.06, 3.09,
3.16, 3.18 and 3.19, (v) the rights, obligations and immunities of the Indenture
Trustee hereunder (including the rights of the Indenture Trustee under Section
6.07 and the obligations of the Indenture Trustee under Section 4.11) and (vi)
the rights of Noteholders as beneficiaries hereof with respect to the property
so deposited with the Indenture Trustee payable to all or any of them, and the
Indenture Trustee, on demand of and at the expense of the Issuer, shall execute
proper instruments acknowledging satisfaction and discharge of this Indenture
with respect to the Notes and shall release and deliver the Collateral to or
upon the order of the Issuer, when

                  (A) either

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

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

                           a.       have become due and payable,

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


                                       26





                           c. have been called for early redemption pursuant to
                  Section 8.07 hereof,

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

                  (B) the Issuer has paid or caused to be paid all other sums
         payable hereunder; and

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

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

         Section 4.12. REPAYMENT OF MONIES HELD BY PAYING AGENT. In connection
with the satisfaction and discharge of this Indenture with respect to the Notes,
all monies then held by any Person other than the Indenture Trustee under the
provisions of this Indenture with respect to such Notes shall, upon demand of
the Issuer, be paid to the Indenture Trustee to be held and applied according to
Section 3.05 and thereupon such Paying Agent shall be released from all further
liability with respect to such monies.

         Section 4.13. TEMPORARY NOTES. Pending the preparation of any
Definitive Notes, the Issuer may execute and upon its written direction, the
Indenture Trustee may authenticate and make available for delivery, temporary
Notes that are printed, lithographed, typewritten,

                                       27





photocopied or otherwise produced, in any denomination, substantially of the
tenor of the Definitive Notes in lieu of which they are issued and with such
appropriate insertions, omissions, substitutions and other variations as the
officers executing such Notes may determine, as evidenced
by their execution of such Notes.

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


                                       28





                                    ARTICLE V

                              DEFAULT AND REMEDIES

         Section 5.01. EVENTS OF DEFAULT. The Issuer shall deliver to the
Indenture Trustee, within five days after learning of the occurrence of an Event
of Default, written notice in the form of an Officer's Certificate of any event
which with the giving of notice and the lapse of time would become an Event of
Default under clause (iii) of the definition of "Event of Default", its status
and what action the Issuer is taking or proposes to take with respect thereto.

         Section 5.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee at the written direction of the Holders of Notes representing
not less than a majority of the Note Principal Balances of the Notes, may
declare the Notes to be immediately due and payable, by a notice in writing to
the Issuer (and to the Indenture Trustee if given by Noteholders), and upon any
such declaration the unpaid Note Principal Balance of the Notes, together with
accrued and unpaid interest thereon through the date of acceleration, shall
become immediately due and payable.

         At any time after such declaration of acceleration of maturity with
respect to an Event of Default has been made and before a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as
hereinafter in this Article V, the Holders of Notes representing a majority of
the Note Principal Balances of all Notes, by written notice to the Issuer and
the Indenture Trustee, may waive the related Event of Default and rescind and
annul such declaration and its consequences if:

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

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

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

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


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


                                       29





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

         (a) The Issuer covenants that if a default is made in the payment of
(i) Accrued Note Interest or Unpaid Interest Shortfalls with respect to any
Class of Notes, (ii) the Principal Distribution Amount with respect to any Class
of Notes, (iii) the Extra Principal Distribution Amount with respect to a
Payment Date, but only to the extent funds are available to make such payment
any interest or (iv) payment of principal in full on the related Final Scheduled
Maturity Date with respect to any Class of Notes, in each case when the same
becomes due and payable, and such default continues for a period of five days,
the Issuer shall, upon demand of the Indenture Trustee, pay to the Indenture
Trustee, for the benefit of the Holders of Notes, the whole amount then due and
payable on the Notes for principal and interest, with interest at the Note
Interest Rate upon the overdue principal, and in addition thereto such further
amount as shall be sufficient to cover the costs and expenses of collection,
including the reasonable compensation, expenses, disbursements and advances of
the Indenture Trustee and its agents and counsel.

         (b) In case the Issuer shall fail forthwith to pay such amounts upon
such demand, the Indenture Trustee, in its own name and as trustee of an express
trust, subject to the provisions of Section 10.16 hereof may institute a
Proceeding for the collection of the sums so due and unpaid, and may prosecute
such Proceeding to judgment or final decree, and may enforce the same against
the Issuer or other obligor upon the Notes and collect in the manner provided by
law out of the property of the Issuer or other obligor the Notes, wherever
situated, the monies adjudged or decreed to be payable.

         (c) If an Event of Default occurs and is continuing, the Indenture
Trustee, subject to the provisions of Section 10.16 hereof may, as more
particularly provided in Section 5.04 hereof, in its discretion, proceed to
protect and enforce its rights and the rights of the Noteholders, by such
appropriate Proceedings as the Indenture Trustee shall deem most effective to
protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power
granted herein, or to enforce any other proper remedy or legal or equitable
right vested in the Indenture Trustee by this Indenture or by law.

         (d) In case there shall be pending, relative to the Issuer or any other
obligor upon the Notes or any Person having or claiming an ownership interest in
the Trust Estate, Proceedings under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor or Person,
or in case of any other comparable judicial Proceedings relative to the Issuer
or other obligor upon the Notes, or to the creditors or property of the Issuer
or such other obligor, the Indenture Trustee, irrespective of whether the
principal of any Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Indenture Trustee shall
have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such Proceedings or otherwise:


                                       30





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

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

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

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

and any trustee, receiver, liquidator, custodian or other similar official in
any such Proceeding is hereby authorized by each of such Noteholders to make
payments to the Indenture Trustee, and, in the event that the Indenture Trustee
shall consent to the making of payments directly to such Noteholders, to pay to
the Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Indenture Trustee and each
predecessor Indenture Trustee except as a result of negligence or bad faith.

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

         (f) All rights of action and of asserting claims under this Indenture,
or under any of the Notes, may be enforced by the Indenture Trustee without the
possession of any of the Notes or the production thereof in any trial or other
Proceedings relative thereto, and any such action or proceedings instituted by
the Indenture Trustee shall be brought in its own name as trustee of an express
trust, and any recovery of judgment, subject to the payment of the expenses,
disbursements and compensation of the Indenture Trustee, each predecessor
Indenture Trustee and

                                       31





their respective agents and attorneys, shall be for the ratable benefit of the
Holders of the Notes, subject to Section 5.05 hereof.

         (g) In any Proceedings brought by the Indenture Trustee (and also any
Proceedings involving the interpretation of any provision of this Indenture to
which the Indenture Trustee shall be a party), the Indenture Trustee shall be
held to represent all the Holders of the Notes, and it shall not be necessary to
make any Noteholder a party to any such Proceedings.

         Section 5.04. REMEDIES; PRIORITIES. (a) If an Event of Default shall
have occurred and be continuing and if an acceleration has been declared and not
rescinded pursuant to Section 5.02 hereof, the Indenture Trustee subject to the
provisions of Section 10.16 hereof shall, do one or more of the following
(subject to Section 5.05 hereof):

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

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

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

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

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Trust Estate following an Event of Default, unless (A) the
Indenture Trustee obtains the consent of the Holders of 100% of the aggregate
Note Principal Balance, (B) the proceeds of such sale or liquidation
distributable to the Holders of the Notes are sufficient to discharge in full
all amounts then due and unpaid upon the Notes for principal and interest or (C)
the Indenture Trustee determines that the Mortgage Loans will not continue to
provide sufficient funds for the payment of principal of and interest on the
Notes as they would have become due if the Notes had not been declared due and
payable, and the Indenture Trustee obtains the consent of the Holders of a
majority of the aggregate Note Principal Balance. In determining such
sufficiency or insufficiency with respect to clause (B) and (C), the Indenture
Trustee may, but need not, obtain and rely upon an opinion of an Independent
investment banking or accounting firm of national reputation as to the
feasibility of such proposed action and as to the sufficiency of the Trust
Estate for such purpose. Notwithstanding the foregoing, so long as an Event of
Servicer Termination has not occurred, any Sale of the Trust Estate shall be
made subject to the continued servicing of the Mortgage Loans by the Master
Servicer as provided in the Servicing Agreement.


                                       32





         (b) If the Indenture Trustee collects any money or property pursuant to
this Article V, it shall pay out the money or property in the following order:

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

                  SECOND: to the Noteholders for amounts due and unpaid on the
                  Notes, first to the Senior Notes without preference or
                  priority of any kind, second to the Class M- 1 Notes, third to
                  the Class M-2 Notes and fourth, to the Class B-1 Notes,
                  according to the amounts due and payable on the Notes for
                  interest (including the Interest Remittance Amount and Unpaid
                  Interest Shortfalls) from amounts available in the Trust
                  Estate for the Noteholders;

                  THIRD: to Noteholders for amounts due and unpaid on the Notes
                  with respect to principal (including, but not limited to, any
                  Principal Distribution Amount), from amounts available in the
                  Trust Estate for such Noteholders, to the Noteholders, the
                  amount of principal then due and unpaid on the Notes, first to
                  the Senior Notes without preference or priority of any kind,
                  second to the Class M-1 Notes, third to the Class M-2 Notes
                  and fourth, to the Class B-1 Notes, in each case until the
                  Note Principal Balance is reduced to zero; and

                  FOURTH: to the payment of the remainder, if any to the Issuer,
                  or the Certificate Paying Agent as its designee, or any other
                  person legally entitled thereto.

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

         Section 5.05. OPTIONAL PRESERVATION OF THE TRUST ESTATE. If the Notes
have been declared to be due and payable under Section 5.02 following an Event
of Default and such declaration and its consequences have not been rescinded and
annulled, the Indenture Trustee shall elect to take and maintain possession of
the Trust Estate. It is the desire of the parties hereto and the Noteholders
that there be at all times sufficient funds for the payment of principal of and
interest on the Notes and other obligations of the Issuer, and the Indenture
Trustee shall take such desire into account when determining whether or not to
take and maintain possession of the Trust Estate. In determining whether to take
and maintain possession of the Trust Estate, the Indenture Trustee may, but need
not, obtain and rely upon an opinion of an Independent investment banking or
accounting firm of national reputation as to the feasibility of such proposed
action and as to the sufficiency of the Trust Estate for such purpose.


                                       33





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

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

                       (ii) the Holders of not less than 25% of the Note
         Principal Balances of the Notes have made a written request to the
         Indenture Trustee to institute such Proceeding in respect of such Event
         of Default in its own name as Indenture Trustee hereunder;

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

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

                        (v) no direction inconsistent with such written request
         has been given to the Indenture Trustee during such 60-day period by
         the Holders of a majority of the Note Principal Balances of the Notes.

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

         Subject to the last paragraph of Section 4.12 herein, in the event the
Indenture Trustee shall receive conflicting or inconsistent requests and
indemnity from two or more groups of Holders of Notes, each representing less
than a majority of the Note Principal Balances of the Notes, the Indenture
Trustee in its sole discretion may determine what action, if any, shall be
taken, notwithstanding any other provisions of this Indenture.

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

         Section 5.08. RESTORATION OF RIGHTS AND REMEDIES. If the Indenture
Trustee or any Noteholder has instituted any Proceeding to enforce any right or
remedy under this Indenture and such Proceeding has been discontinued or
abandoned for any reason or has been determined

                                       34





adversely to the Indenture Trustee or to such Noteholder, then and in every such
case the Issuer, the Indenture Trustee and the Noteholders shall, subject to any
determination in such Proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Indenture Trustee and the Noteholders shall continue as though no such
Proceeding had been instituted.

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

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

         Section 5.11. CONTROL BY NOTEHOLDERS. The Holders of a majority of the
Note Principal Balances of Notes shall have the right (subject to the provisions
of Section 5.06) to direct the time, method and place of conducting any
Proceeding for any remedy available to the Indenture Trustee with respect to the
Notes or exercising any trust or power conferred on the
Indenture Trustee; provided that:

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

                        (ii) any direction to the Indenture Trustee to sell or
         liquidate the Trust Estate shall be by Holders of Notes representing
         not less than 100% of the Note Principal Balances of Notes;

                        (iii) if the conditions set forth in Section 5.05 hereof
         have been satisfied and the Indenture Trustee elects to retain the
         Trust Estate pursuant to such Section, then any direction to the
         Indenture Trustee by Holders of Notes representing less than 100% of
         the Note Principal Balances of Notes to sell or liquidate the Trust
         Estate shall be of no force and effect; and

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


                                       35





Notwithstanding the rights of Noteholders set forth in this Section, subject to
Section 6.01, the Indenture Trustee need not take any action that it determines
might involve it in liability or might materially adversely affect the rights of
any Noteholders not consenting to such action.

         Section 5.12. WAIVER OF PAST DEFAULTS. Prior to the declaration of the
acceleration of the maturity of the Notes as provided in Section 5.02 hereof,
the Holders of Notes of not less than a majority of the Note Principal Balances
of the Notes may waive any past Event of Default and its consequences except an
Event of Default (a) with respect to payment of principal of or interest on any
of the Notes or (b) in respect of a covenant or provision hereof which cannot be
modified or amended without the consent of the Holder of each Note. In the case
of any such waiver, the Issuer, the Indenture Trustee and the Holders of the
Notes shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other Event
of Default or impair any right consequent thereto.

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

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

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

         Section 5.15. SALE OF TRUST ESTATE. (a) The power to effect any sale or
other disposition (a "Sale") of any portion of the Trust Estate pursuant to
Section 5.04 hereof is expressly subject to the provisions of Section 5.05
hereof and this Section 5.15. The power to effect any such Sale shall not be
exhausted by any one or more Sales as to any portion of the Trust

                                       36





Estate remaining unsold, but shall continue unimpaired until the entire Trust
Estate shall have been sold or all amounts payable on the Notes and under this
Indenture shall have been paid. The Indenture Trustee may from time to time
postpone any public Sale by public announcement made at the time and place of
such Sale. The Indenture Trustee hereby expressly waives its right to any amount
fixed by law as compensation for any Sale.

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

                  (1) the Holders of all Notes, consent to or direct the
Indenture Trustee to make, such Sale, or

                  (2) the proceeds of such Sale would be not less than the
entire amount which would be payable to the Noteholders under the Notes on the
Payment Date next succeeding the date of such Sale; or

                  (3) Indenture Trustee determines, that the conditions for
retention of the Trust Estate set forth in Section 5.05 hereof cannot be
satisfied (in making any such determination, the Indenture Trustee may rely upon
an opinion of an Independent investment banking firm obtained and delivered as
provided in Section 5.05 hereof), and the Holders of Notes representing at least
a majority of the Note Principal Balances of the Notes consent to such Sale.

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

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

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

                  (1) any Holder or Holders of Notes may bid for the property
offered for sale, and upon compliance with the terms of sale may hold, retain
and possess and dispose of such property, without further accountability, and
may, in paying the purchase money therefor, deliver any Notes or claims for
interest thereon in lieu of cash up to the amount which shall, upon distribution
of the net proceeds of such sale, be payable thereon, and such Notes, in case
the amounts so payable thereon shall be less than the amount due thereon, shall
be returned to the Holders thereof after being appropriately stamped to show
such partial payment;

                  (2) the Indenture Trustee may bid for and acquire the property
offered for Sale in connection with any Sale thereof, and, subject to any
requirements of, and to the extent

                                       37





permitted by, applicable law in connection therewith, may purchase all or any
portion of the Trust Estate in a private sale, and, in lieu of paying cash
therefor, may make settlement for the purchase price by crediting the gross Sale
price against the sum of (A) the amount which would be distributable to the
Holders of the Notes and Holders of Certificates as a result of such Sale in
accordance with Section 5.04(b) hereof on the Payment Date next succeeding the
date of such Sale and (B) the expenses of the Sale and of any Proceedings in
connection therewith which are reimbursable to it, without being required to
produce the Notes in order to complete any such Sale or in order for the net
Sale price to be credited against such Notes, and any property so acquired by
the Indenture Trustee shall be held and dealt with by it in accordance with the
provisions of this Indenture;

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

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

                  (5) no purchaser or transferee at such a Sale shall be bound
to ascertain the Indenture Trustee's authority, inquire into the satisfaction of
any conditions precedent or see to the application of any monies.

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

         Section 5.17. PERFORMANCE AND ENFORCEMENT OF CERTAIN OBLIGATIONS. (a)
Promptly following a request from the Indenture Trustee to do so, the Issuer in
its capacity as holder of the Mortgage Loans, shall take all such lawful action
as the Indenture Trustee may request to cause the Issuer to compel or secure the
performance and observance by the Seller and the Master Servicer, as applicable,
of each of their obligations to the Issuer under or in connection with the
Mortgage Loan Purchase Agreement and the Servicing Agreement, and to exercise
any and all rights, remedies, powers and privileges lawfully available to the
Issuer under or in connection with the Mortgage Loan Purchase Agreement and the
Servicing Agreement to the extent and in the manner directed by the Indenture
Trustee as pledgee of the Mortgage Loans, including the transmission of notices
of default on the part of the Seller or the Master Servicer thereunder and the
institution of legal or administrative actions or proceedings to compel or
secure performance by the Seller or the Master Servicer of each of their
obligations under the Mortgage Loan Purchase Agreement and the Servicing
Agreement.

                                       38





         (b) The Indenture Trustee, as pledgee of the Mortgage Loans, may, and
at the direction (which direction shall be in writing or by telephone (confirmed
in writing promptly thereafter)) of Holders of 66-2/3% of the Note Principal
Balances of the Notes, shall exercise all rights, remedies, powers, privileges
and claims of the Issuer against the Seller or the Master Servicer under or in
connection with the Mortgage Loan Purchase Agreement and the Servicing
Agreement, including the right or power to take any action to compel or secure
performance or observance by the Seller or the Master Servicer, as the case may
be, of each of their obligations to the Issuer thereunder and to give any
consent, request, notice, direction, approval, extension or waiver under the
Mortgage Loan Purchase Agreement and the Servicing Agreement, as the case may
be, and any right of the Issuer to take such action shall not be suspended.

                                       39





                                   ARTICLE VI

                              THE INDENTURE TRUSTEE

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

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

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

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

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

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

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

                        (iii) the Indenture Trustee shall not be liable with

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

                                       40





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

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

         (h) The Indenture Trustee shall act in accordance with Sections 6.03

fact or matter stated in the document.

         (b) Before the Indenture Trustee acts or refrains from acting, it may

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

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

         Section 6.04. INDENTURE TRUSTEE'S DISCLAIMER. The Indenture Trustee
shall not be responsible for and makes no representation as to the validity or

any statement of the Issuer in the Indenture or in any document issued in
connection with the sale of the Notes or in the Notes other than the Indenture
Trustee's certificate of authentication.


                                       41





         Section 6.05. NOTICE OF EVENT OF DEFAULT. The Indenture Trustee shall
mail to each Noteholder notice of the Event of Default within 10 days after it
is known to a Responsible Officer of the Indenture Trustee, unless such Event of
Default shall have been waived or cured. Except in the case of an Event of
Default in payment of principal of or interest on any Note, the Indenture
Trustee may withhold the notice if and so long as a committee of its Responsible
Officers in good faith determines that withholding the notice is in the
interests of Noteholders.

         Section 6.06. REPORTS BY INDENTURE TRUSTEE TO HOLDERS. The Indenture
Trustee shall deliver to each Noteholder such information as may be required to
enable such holder to prepare its federal and state income tax returns. In
addition, upon the Issuer's written request, the Indenture Trustee shall
promptly furnish information reasonably requested by the Issuer that is
reasonably available to the Indenture Trustee to enable the Issuer to perform
its federal and state income tax reporting obligations.

         Section 6.07. COMPENSATION AND INDEMNITY. The Issuer shall pay to the
Indenture Trustee on each Payment Date reasonable compensation for its services.
The amount of the Indenture Trustee Fee shall be paid by the Master Servicer to
the Indenture Trustee on each Payment Date pursuant to Section 3.07(a)(x) of the
Servicing Agreement, and all amounts owing to the Indenture Trustee hereunder in
excess of such amount shall be paid solely as provided in a separate agreement
between the Indenture Trustee and the Master Servicer. The Indenture Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Issuer shall reimburse the Indenture Trustee for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, in addition to compensation for its services. Such expenses shall
include reasonable compensation and expenses, disbursements and advances of the
Indenture Trustee's agents, counsel, accountants and experts. The Issuer shall
indemnify the Indenture Trustee against any and all loss, liability or expense
(including attorneys' fees) incurred by it in connection with the administration
of this Trust and the performance of its duties hereunder. The Indenture Trustee
shall notify the Issuer promptly of any claim for which it may seek indemnity.
Failure by the Indenture Trustee to so notify the Issuer shall not relieve the
Issuer of its obligations hereunder. The Issuer shall defend any such claim, and
the Indenture Trustee may have separate counsel and the Issuer shall pay the
fees and expenses of such counsel. The Issuer is not obligated to reimburse any
expense or indemnify against any loss, liability or expense incurred by the
Indenture Trustee through the Indenture Trustee's own willful misconduct, negli
gence or bad faith.

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

         Section 6.08. REPLACEMENT OF INDENTURE TRUSTEE. No resignation or
removal of the Indenture Trustee and no appointment of a successor Indenture
Trustee shall become effective until the acceptance of appointment by the
successor Indenture Trustee pursuant to this Section 6.08. The Indenture Trustee
may resign at any time by so notifying the Issuer. The Holders of a

                                       42





majority of Note Principal Balances of the Notes may remove the Indenture
Trustee by so notifying the Indenture Trustee and may appoint a successor
Indenture Trustee. The Issuer shall remove the Indenture Trustee if:

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

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

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

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

         If the Indenture Trustee resigns or is removed or if a vacancy exists
in the office of the Indenture Trustee for any reason (the Indenture Trustee in
such event being referred to herein as the retiring Indenture Trustee), the
Issuer shall promptly appoint a successor Indenture
Trustee.

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

         If a successor Indenture Trustee does not take office within 60 days
after the retiring Indenture Trustee resigns or is removed, the retiring
Indenture Trustee, the Issuer or the Holders of a majority of Note Principal
Balances of the Notes may petition any court of competent jurisdiction for the
appointment of a successor Indenture Trustee.

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

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

         If at the time such successor or successors by merger, conversion or
consolidation to the Indenture Trustee shall succeed to the trusts created by
this Indenture and any of the Notes shall have been authenticated but not
delivered, any such successor to the Indenture Trustee may adopt the certificate
of authentication of any predecessor trustee and deliver such Notes so
authenticated;

                                       43





and if at that time any of the Notes shall not have been authenticated, any
successor to the Indenture Trustee may authenticate such Notes either in the
name of any predecessor hereunder or in the name of the successor to the
Indenture Trustee; and in all such cases such certificates shall have the full
force which it is in the Notes or in this Indenture provided that the
certificate of the Indenture Trustee shall have.

         Section 6.10. APPOINTMENT OF CO-INDENTURE TRUSTEE OR SEPARATE INDENTURE
TRUSTEE. (a) Notwithstanding any other provisions of this Indenture, at any
time, for the purpose of meet ing any legal requirement of any jurisdiction in
which any part of the Trust Estate may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, or separate
trustee or separate trustees, of all or any part of the Trust Estate, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Noteholders, such title to the Trust Estate, or any part hereof, and, subject to
the other provisions of this Section, such powers, duties, obligations, rights
and trusts as the Indenture Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 6.11 hereof and no notice to
the Noteholders of the appointment of any co-trustee or separate trustee shall
be required.

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

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

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

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

         (c) Any notice, request or other writing given to the Indenture Trustee
shall be deemed to have been given to each of the then separate trustees and
co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Agreement 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

                                       44





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 Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Indenture Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

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

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

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

         this Indenture and the fulfillment of the terms hereof do not conflict
         with, result in any breach of any of the terms and provisions of, or
         constitute (with or without notice or lapse of time) a default under,
         the articles of organization or bylaws of the Indenture Trustee or any
         agreement or other instrument to which the Indenture Trustee is a party
         or by which it is bound; and

                    (iv) To the Indenture Trustee's best knowledge, there are no

         to prevent the consummation of any of the transactions contemplated by
         this Indenture or (C) seeking any determination or ruling that might
         materially and adversely affect the performance by the Indenture

                      ACCOUNTS, DISBURSEMENTS AND RELEASES

         Section 8.01. COLLECTION OF MONEY. Except as otherwise expressly
provided herein, the Indenture Trustee may demand payment or delivery of, and
shall receive and collect, directly and without intervention or assistance of
any fiscal agent or other intermediary, all money and other property payable to
or receivable by the Indenture Trustee pursuant to this Indenture. The Indenture
Trustee shall apply all such money received by it as provided in this Indenture.
Except as otherwise expressly provided in this Indenture, if any default occurs
in the making of any payment or performance under any agreement or instrument
that is part of the Trust Estate, the Indenture Trustee may take such action as
may be appropriate to enforce such payment or performance, including the
institution and prosecution of appropriate Proceedings. Any such action shall be
without prejudice to any right to claim a Default or Event of Default under this
Indenture and any right to proceed thereafter as provided in Article V.

         Section 8.02. TRUST ACCOUNTS.

         On or prior to the Closing Date, the Issuer shall cause the Indenture
Trustee to establish and maintain, in the name of the Indenture Trustee, for the
benefit of the Noteholders, the Payment Account as provided in Section 3.01
hereof.

          All monies deposited from time to time in the Payment Account and all
investments made with such monies including all income or other gain from such
investments pursuant to the Servicing Agreement and all deposits therein
pursuant to this Indenture are for the benefit of the Noteholders. The amount of
any losses incurred with respect to any such investments shall be deposited in
the Payment Account by the Master Servicer.

         On each Payment Date, the Indenture Trustee shall distribute all
amounts on deposit in the Payment Account, after payment to the Indenture
Trustee of the Indenture Trustee Fee and payment to the Owner Trustee of the
Owner Trustee Fee, to the Noteholders in respect of the Notes and to such other
persons in the order of priority set forth in Section 3.05 hereof (except
as otherwise provided in Section 5.04(b) hereof).

         The Indenture Trustee shall invest any funds in the Payment Account in
Eligible Investments, as directed by the Master Servicer, maturing no later than
the Business Day preceding each Payment Date and such Eligible Investments shall
not be sold or disposed of prior to their maturity. In the absence of such
direction, the Indenture Trustee shall invest the funds in the Payment Account
in money market funds as further described in clause (vii) of the definition of
Eligible Investments.

         Section 8.03. OFFICER'S CERTIFICATE. The Indenture Trustee shall
receive at least seven days' notice when requested by the Issuer to take any
action pursuant to Section 8.05(a) hereof, accompanied by copies of any
instruments to be executed, and the Indenture Trustee shall also require, as a
condition to such action, an Officer's Certificate, in form and substance
satisfactory

                                       50





to the Indenture Trustee, 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.

         Section 8.04. TERMINATION UPON DISTRIBUTION TO NOTEHOLDERS. This
Indenture and the respective obligations and responsibilities of the Issuer and
the Indenture Trustee created hereby shall terminate upon the distribution to
Noteholders, the Certificate Paying Agent on behalf of the Certificateholders
and the Indenture Trustee of all amounts required to be distributed pursuant to
Article III; provided, however, that in no event shall the trust created hereby
continue beyond the expiration of 21 years from the death of the survivor of the
descendants of Joseph P. Kennedy, the late ambassador of the United States to
the Court of St. James, living on the date hereof.

         Section 8.05. RELEASE OF TRUST ESTATE. (a) Subject to the payment of
its fees and expenses, the Indenture Trustee may, and when required by the
provisions of this Indenture shall, execute instruments to release property from
the lien of this Indenture, or convey the Indenture Trustee's interest in the
same, in a manner and under circumstances that are not inconsistent with the
provisions of this Indenture. No party relying upon an instrument executed by
the Indenture Trustee as provided in Article VIII hereunder shall be bound to
ascertain the Indenture Trustee's authority, inquire into the satisfaction of
any conditions precedent, or see to the application of any monies.

         (b) The Indenture Trustee shall, at such time as (i) there are no Notes
Outstanding and (ii) all sums due to the Indenture Trustee pursuant to this
Indenture have been paid, release any remaining portion of the Trust Estate that
secured the Notes from the lien of this Indenture.

         (c) The Indenture Trustee shall release property from the lien of this
Indenture pursuant to this Section 8.05 only upon receipt of a request from the
Issuer accompanied by an Officers' Certificate and an Opinion of Counsel stating
that all applicable requirements have been
satisfied.

         Section 8.06. SURRENDER OF NOTES UPON FINAL PAYMENT. By acceptance of
any Note, the Holder thereof agrees to surrender such Note to the Indenture
Trustee promptly, prior to such Noteholder's receipt of the final payment
thereon.

         Section 8.07. OPTIONAL REDEMPTION OF THE NOTES. (a) The Issuer shall
have the option to redeem the Notes in whole, but not in part, on any Payment
Date on which the aggregate Principal Balance of the Mortgage Loans is less than
or equal to 10.00% of the aggregate Principal Balance of the Mortgage Loans as
of the Cut-off Date. The aggregate redemption price for the Notes will be equal
to the unpaid Note Principal Balance of the Notes as of the Payment Date on
which the proposed redemption will take place in accordance with the foregoing,
together with accrued and unpaid interest thereon at the Note Interest Rate
through such Payment Date, plus an amount sufficient to pay in full all amounts
owing to the Indenture Trustee under this Indenture (which amounts shall be
specified in writing upon request of the Issuer by the Indenture Trustee).

         (b) In order to exercise the foregoing option, the Issuer shall, not
less than 15 days prior to the proposed Payment Date on which such redemption is
to be made, deposit the aggregate

                                       51





redemption price specified in (a) above with the Indenture Trustee, and shall
provide written notice of its exercise of such option to the Indenture Trustee,
the Owner Trustee and the Master Servicer. Following receipt of the notice and
the aggregate redemption price, calculated as specified in Section 8.07(a)
hereof, pursuant to the foregoing, the Indenture Trustee shall provide notice to
the Noteholders of the final payment on the Notes and shall apply such funds to
make final payments of principal and interest on the Notes in accordance with
Section 3.05(b) hereof, and this Indenture shall be discharged subject to the
provisions of Section 4.10 hereof. If for any reason the amount deposited by the
Issuer is not sufficient to make such redemption or such redemption cannot be
completed for any reason, the amount so deposited by the Issuer with the
Indenture Trustee shall be immediately returned to the Issuer in full and shall
not be used for any other purpose or be deemed to be part of the Trust Estate.

                             SUPPLEMENTAL INDENTURES

         Section 9.01. SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF NOTEHOLDERS.
(a) Without the consent of the Holders of any Notes but with prior notice to the
Rating Agencies, the Issuer and the Indenture Trustee, when authorized by an
Issuer Request, at any time and from time to time, may enter into one or more
indentures supplemental hereto (which shall conform to the provisions of the TIA
as in force at the date of the execution thereof), in form satisfactory to the
Indenture Trustee, 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, convey and confirm unto the Indenture Trustee any property
         subject or required to be subjected to the lien of this Indenture, or
         to subject to the lien of this Indenture additional property;

                         (ii) to evidence the succession, in compliance with the
         applicable provisions hereof, of another person to the Issuer, and the
         assumption by any such successor of the covenants of the Issuer herein
         and in the Notes contained;

                         (iii) to add to the covenants of the Issuer, for the
         benefit of the Holders of the Notes, or to surrender any right or power
         herein conferred upon the Issuer;

                         (iv) to convey, transfer, assign, mortgage or pledge
         any property to or with the Indenture Trustee;

                         (v) to cure any ambiguity, to correct or supplement any
         provision herein or in any supplemental indenture that may be
         inconsistent with any other provision herein or in any supplemental
         indenture;

                         (vi) to make any other provisions with respect to
         matters or questions arising under this Indenture or in any
         supplemental indenture; provided, that such action shall not materially
         and adversely affect the interests of the Holders of the Notes;

                         (vii) to evidence and provide for the acceptance of the
         appointment hereunder by a successor trustee with respect to the Notes
         and to add to or change any of the provisions of this Indenture as
         shall be necessary to facilitate the administration of the trusts
         hereunder by more than one trustee, pursuant to the requirements of
         Article VI hereof; or

                         (viii) to modify, eliminate or add to the provisions of
         this Indenture to such extent as shall be necessary to effect the
         qualification of this Indenture under the TIA or under any similar
         federal statute hereafter enacted and to add to this Indenture such
         other provisions as may be expressly required by the TIA;


                                       53





provided, however, that no such indenture supplements shall be entered into
unless the Indenture Trustee shall have received an Opinion of Counsel that
entering into such indenture supplement will not result in a "substantial
modification" of the Notes under Treasury Regulation Section 1.1001.3 or
adversely affect the status of the Notes as indebtedness for federal income tax
purposes.

         The Indenture Trustee is hereby authorized to join in the execution of
any such supplemental indenture and to make any further appropriate agreements
and stipulations that may
be therein contained.

         (b) The Issuer and the Indenture Trustee, when authorized by an Issuer
Request, may, also without the consent of any of the Holders of the Notes but
with prior notice to the Rating Agencies, 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 the Notes under this
Indenture; provided, however, that such action shall not, as evidenced by an
Opinion of Counsel, (i) adversely affect in any material respect the interests
of any Noteholder or (ii) if 100% of the Certificates are not owned by Impac
Secured Assets Corp., cause the Issuer to be subject to an entity level tax for
federal income tax purposes.

         Section 9.02. SUPPLEMENTAL INDENTURES WITH CONSENT OF NOTEHOLDERS. The
Issuer and the Indenture Trustee, when authorized by an Issuer Request, also
may, with prior notice to the Rating Agencies and, with the consent of the
Holders of not less than a majority of the Note Principal Balances of the Notes
affected thereby, by Act (as defined in Section 10.03 hereof) of such Holders
delivered to the Issuer and the Indenture Trustee, 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 the Notes under this
Indenture; provided, however, that no such supplemental indenture shall, without
the consent of the Holder of each Note affected thereby:

                         (i) change the date of payment of any installment of
         principal of or interest on any Note, or reduce the principal amount
         thereof or the interest rate thereon, change the provisions of this
         Indenture relating to the application of collections on, or the
         proceeds of the sale of, the Trust Estate to payment of principal of or
         interest on the Notes, or change any place of payment where, or the
         coin or currency in which, any Note or the interest thereon is payable,
         or impair the right to institute suit for the enforcement of the
         provisions of this Indenture requiring the application of funds
         available therefor, as provided in Article V, to the payment of any
         such amount due on the Notes on or after the respective due dates
         thereof;

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

                                       54





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

                         (iv) reduce the percentage of the Note Principal
         Balances of the Notes required to direct the Indenture Trustee to
         direct the Issuer to sell or liquidate the Trust Estate pursuant to
         Section 5.04 hereof;

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

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

                         (vii) permit the creation of any lien ranking prior to
         or on a parity with the lien of this Indenture with respect to any part
         of the Trust Estate or, except as otherwise permitted or contemplated
         herein, terminate the lien of this Indenture on any property at any
         time subject hereto or deprive the Holder of any Note of the security
         provided by the lien of this Indenture; and provided, further, that
         such action shall not, as evidenced by an Opinion of Counsel, cause the
         Issuer (if 100% of the Certificates are not owned by Impac Secured
         Assets Corp.) to be subject to an entity level tax.

         The Indenture Trustee may, in its discretion determine whether or not
any Notes would be affected by any supplemental indenture and any such
determination shall be conclusive upon the Holders of all Notes, whether
theretofore or thereafter authenticated and delivered hereunder. The Indenture
Trustee shall not be liable for any such determination made in good faith.

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

         Promptly after the execution by the Issuer and the Indenture Trustee of
any supplemental indenture pursuant to this Section 9.02, the Indenture Trustee
shall mail to the Holders of the Notes to which such amendment or supplemental
indenture relates a notice setting forth in general terms the substance of such
supplemental indenture. Any failure of the Indenture Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

         Section 9.03. EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or
permitting the additional trusts created by, any supplemental indenture
permitted by this Article IX or the modification thereby of the trusts created
by this Indenture, the Indenture Trustee shall be entitled to receive, and
subject to Sections 6.01 and 6.02 hereof, shall be fully protected in relying
upon,

                                       55





an Opinion of Counsel stating that the execution of such supplemental indenture
is authorized or permitted by this Indenture. The Indenture Trustee may, but
shall not be obligated to, enter into any such supplemental indenture that
affects the Indenture Trustee's own rights, duties, liabilities or immunities
under this Indenture or otherwise.

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

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

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


                                       56

the Indenture Trustee an Officer's Certificate certifying or stating the opinion
of any signer thereof as to the matters described in clause (iii) above, the

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

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

                                       58





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

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

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

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

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

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

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

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

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

                            (ii) the Issuer by the Indenture Trustee or by any
         Noteholder shall be sufficient for every purpose hereunder if in
         writing and mailed first-class, postage prepaid to the Issuer addressed
         to: Impac Secured Assets CMN Trust Series 1998-1, in care of Wilmington
         Trust Company, Rodney Square North, 1100 North Market Street,
         Wilmington, Delaware 19890-0001, Attention: Corporate Trust
         Administration, or at any other address previously furnished in writing
         to the Indenture Trustee by the Issuer. The Issuer shall promptly
         transmit any notice received by it from the Noteholders to the
         Indenture Trustee.

         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
or mailed first-class postage pre-paid, to (i) in the case of Moody's, at the
following address: Moody's Investors Service, Inc., Residential Mortgage
Monitoring Department, 99 Church Street, New York, New York 10007 and (ii) in
the case of Fitch, at the following address: One State Street Plaza, 33rd Floor,
New York, NY 10004; or as to each of the foregoing, at such other address as
shall be designated by written notice to the other parties.

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

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


                                       60





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

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

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

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

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

         Section 10.08. SUCCESSORS AND ASSIGNS. All covenants and agreements in

assigns, whether so expressed or not. All agreements of the Indenture Trustee in
this Indenture shall bind its successors, co-trustees and agents.

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

         Section 10.10. BENEFITS OF INDENTURE. Nothing in this Indenture or in
the Notes, express or implied, shall give to any Person, other than the parties
hereto and their successors hereunder, and the Noteholders, any benefit or any
legal or equitable right, remedy or claim under this Indenture.

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

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

                                       61





RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE
WITH SUCH LAWS.

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

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

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

         Section 10.16. NO PETITION. The Indenture Trustee, by entering into
this Indenture, and each Noteholder, by accepting a Note, hereby covenant and

bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings,
or other proceedings under any United States federal or state bankruptcy or
similar law in connection with any obligations relating to the Notes, this
Indenture or any of the Basic Documents. This Section 10.16 will survive for one
year following the termination of this Indenture.

         Section 10.17. INSPECTION. The Issuer agrees that, on reasonable prior
notice, it shall permit any representative of the Indenture Trustee, during the
Issuer's normal business hours, to examine all the books of account, records,

to cause such books to be audited by Independent certified public

                                       62





accountants, and to discuss the Issuer's affairs, finances and accounts with the
Issuer's officers, employees, and Independent certified public accountants, all
at such reasonable times and as often as may be reasonably requested. The
Indenture Trustee shall cause its representatives to hold in confidence all such
information except to the extent disclosure may be required by law (and all
reasonable applications for confidential treatment are unavailing) and except to
the extent that the Indenture Trustee may reasonably determine that such
disclosure is consistent with its obligations hereunder.

         Impac Secured Assets CMN Trust Series 1998-1 (the "Issuer"), a Delaware
business trust, for value received, hereby promises to pay to __________ or
registered assigns, the principal sum of ______________________________________
($___________) in monthly installments on the twenty-fifth day of each month or,
if such day is not a Business Day, the next succeeding Business Day (each a
"Payment Date"), commencing in April 1998 and ending on or before the Payment
Date occurring in _______ 201_ and to pay interest on the Note Principal Balance
of this Class A-___ Note ( this "Note") outstanding from time to time as
provided below.

         This Note is one of a duly authorized issue of the Issuer's
Collateralized Asset-Backed Notes, Series 1998-1, (the "Notes"), issued under an
Indenture dated as of March 31, 1998 (the "Indenture"), between the Issuer and
Bankers Trust Company of California, N.A., as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee, and the Holders of the Notes and the terms upon
which the Notes are to be authenticated and delivered. All terms used in this
Note which are defined in the Indenture shall have the meanings assigned to them
in the Indenture.

         Payments of principal and interest on this Note will be made on each
Payment Date to the Noteholder of record as of the related Record Date. On each
Payment Date, Noteholders will be entitled to receive interest payments in an
aggregate amount equal to the Interest Remittance Amount for such Payment Date,
together with principal payments in an aggregate amount equal to the Principal
Distribution Amount plus the Net Monthly Excess Cash Flow, if any, for such
Payment Date. The "Note Principal Balance" of a Note as of any date of
determination is equal to the initial Note Principal Balance thereof, reduced by
the aggregate of all amounts previously paid with respect to such Note on
account of principal.

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

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

         The Notes are subject to redemption in whole, but not in part, by the
Issuer on any Payment Date on or after the Payment Date on which the aggregate
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
Original Pool Principal Balance.

         The Issuer shall not be liable upon the indebtedness evidenced by the
Notes except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Notes. The assets included in the
Trust Estate will be the sole source of payments on the Notes, and each Holder
hereof, by its acceptance of this Note, agrees that (i) such Note will be
limited in right of payment to amounts available from the Trust Estate as
provided in the Indenture






and (ii) such Holder shall have no recourse to the Issuer, the Owner Trustee,
the Indenture Trustee, Impac Secured Assets Corp., Imperial Credit Mortgage
Holdings, Inc., the Master Servicer or any of their respective affiliates, or to
the assets of any of the foregoing entities, except the assets of the Issuer
pledged to secure the Notes pursuant to the Indenture and the rights
conveyed to the Issuer under the Indenture.

         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note (or one or more Predecessor Notes) is registered at the
close of business on the Record Date for such Payment Date by check mailed to
such person's address as it appears in the Note Register on such Record Date,
except for the final installment of principal and interest payable with respect
to such Note, which shall be payable as provided below. Notwithstanding the
foregoing, upon written request with appropriate instructions by the Holder of
this Note (holding an aggregate Initial Note Principal Balance of at least
$5,000,000) delivered to the Indenture Trustee at least five Business Days prior
to the Record Date, any payment of principal or interest, other than the final
installment of principal or interest, shall be made by wire transfer to an
account in the United States designated by such Holder. All reductions in the
principal amount of a Note (or one or more Predecessor Notes) effected by
payments of principal made on any Payment Date shall be binding upon all Holders
of this Note and of any note issued upon the registration of transfer thereof or
in exchange therefor or in lieu thereof, whether or not such payment is noted on
such Note. The final payment of this Note shall be payable upon presentation and
surrender thereof on or after the Payment Date thereof at the Corporate Trust
Office or the office or agency of the Issuer maintained by it for such purpose
pursuant to Section 3.02 of the Indenture.

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

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

         The failure to pay any Net Monthly Excess Cash Flow at any time when
funds are not available to make such payment as provided in the Indenture shall
not constitute an Event of Default under the Indenture.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Note may be registered on the Note Register of
the Issuer. Upon surrender for registration

                                      -69-





of transfer of, or presentation of a written instrument of transfer for, this
Note at the office or agency designated by the Issuer pursuant to the Indenture,
accompanied by proper instruments of assignment in form satisfactory to the
Indenture Trustee, one or more new Notes of any authorized denominations and of
a like aggregate initial Note Principal Balance, will be issued to the
designated transferee or transferees.

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

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

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

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

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

                                      -70-





         IN WITNESS WHEREOF, the Issuer has caused this instrument to be duly
executed by Wilmington Trust Company, not in its individual capacity but solely

         Impac Secured Assets CMN Trust Series 1998-1 (the "Issuer"), a Delaware
business trust, for value received, hereby promises to pay to __________ or
registered assigns, the principal sum of ______________________________________
($___________) in monthly installments on the twenty-fifth day of each month or,
if such day is not a Business Day, the next succeeding Business Day (each a

Date occurring in ______ 201_ and to pay interest on the Note Principal Balance
of this Class M- ___ Note ( this "Note") outstanding from time to time as
provided below.


                                       -3-





         This Note is one of a duly authorized issue of the Issuer's
Collateralized Asset-Backed Notes, Series 1998-1, (the "Notes"), issued under an
Indenture dated as of March 31, 1998 (the "Indenture"), between the Issuer and
Bankers Trust Company of California, N.A., as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee, and the Holders of the Notes and the terms upon
which the Notes are to be authenticated and delivered. All terms used in this
Note which are defined in the Indenture shall have the meanings assigned to them
in the Indenture.

         Payments of principal and interest on this Note will be made on each
Payment Date to the Noteholder of record as of the related Record Date. On each
Payment Date, Noteholders will be entitled to receive interest payments in an
aggregate amount equal to the Interest Remittance Amount for such Payment Date,
together with principal payments in an aggregate amount equal to the Principal
Distribution Amount plus the Net Monthly Excess Cash Flow, if any, for such
Payment Date. The "Note Principal Balance" of a Note as of any date of
determination is equal to the initial Note Principal Balance thereof, reduced by
the aggregate of all amounts previously paid with respect to such Note on
account of principal and the aggregate amount of cumulative Realized Losses
allocated to such Note on all prior Payment Dates.

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

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

         The Notes are subject to redemption in whole, but not in part, by the
Issuer on any Payment Date on or after the Payment Date on which the aggregate
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
Original Pool Balance.

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







         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note (or one or more Predecessor Notes) is registered at the
close of business on the Record Date for such Payment Date by check mailed to
such person's address as it appears in the Note Register on such Record Date,
except for the final installment of principal and interest payable with respect
to such Note, which shall be payable as provided below. Notwithstanding the
foregoing, upon written request with appropriate instructions by the Holder of
this Note (holding an aggregate Initial Note Principal Balance of at least
$5,000,000) delivered to the Indenture Trustee at least five Business Days prior
to the Record Date, any payment of principal or interest, other than the final
installment of principal or interest, shall be made by wire transfer to an
account in the United States designated by such Holder. All reductions in the
principal amount of a Note (or one or more Predecessor Notes) effected by
payments of principal made on any Payment Date shall be binding upon all Holders
of this Note and of any note issued upon the registration of transfer thereof or
in exchange therefor or in lieu thereof, whether or not such payment is noted on
such Note. The final payment of this Note shall be payable upon presentation and
surrender thereof on or after the Payment Date thereof at the Corporate Trust
Office or the office or agency of the Issuer maintained by it for such purpose
pursuant to Section 3.02 of the Indenture.

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

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

         The failure to pay any Net Monthly Excess Cash Flow at any time when
funds are not available to make such payment as provided in the Indenture shall
not constitute an Event of Default under the Indenture.

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


                                       -5-





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

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

         The Notes are exchangeable for a like aggregate initial Note Principal
Balance of Notes of different authorized denominations, as requested by the
Holder surrendering same.

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

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

                                       -6-





         IN WITNESS WHEREOF, the Issuer has caused this instrument to be duly

                                       -3-





         This Note is one of a duly authorized issue of the Issuer's
Collateralized Asset-Backed Notes, Series 1998-1, (the "Notes"), issued under an
Indenture dated as of March 31, 1998 (the "Indenture"), between the Issuer and
Bankers Trust Company of California, N.A., as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee, and the Holders of the Notes and the terms upon
which the Notes are to be authenticated and delivered. All terms used in this
Note which are defined in the Indenture shall have the meanings assigned to them
in the Indenture.

         Payments of principal and interest on this Note will be made on each
Payment Date to the Noteholder of record as of the related Record Date. On each
Payment Date, Noteholders will be entitled to receive interest payments in an
aggregate amount equal to the Interest Remittance Amount for such Payment Date,
together with principal payments in an aggregate amount equal to the Principal
Distribution Amount plus the Net Monthly Excess Cash Flow, if any, for such
Payment Date. The "Note Principal Balance" of a Note as of any date of
determination is equal to the initial Note Principal Balance thereof, reduced by
the aggregate of all amounts previously paid with respect to such Note on
account of principal and the aggregate amount of cumulative Realized Losses
allocated to such Note on all prior Payment Dates.

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

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

         The Notes are subject to redemption in whole, but not in part, by the
Issuer on any Payment Date on or after the Payment Date on which the aggregate
Principal Balance of the Mortgage Loans is less than or equal to 10% of the
Original Pool Balance.

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







         Any payment of principal or interest payable on this Note which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Note (or one or more Predecessor Notes) is registered at the
close of business on the Record Date for such Payment Date by check mailed to
such person's address as it appears in the Note Register on such Record Date,
except for the final installment of principal and interest payable with respect
to such Note, which shall be payable as provided below. Notwithstanding the
foregoing, upon written request with appropriate instructions by the Holder of
this Note (holding an aggregate Initial Note Principal Balance of at least
$5,000,000) delivered to the Indenture Trustee at least five Business Days prior
to the Record Date, any payment of principal or interest, other than the final
installment of principal or interest, shall be made by wire transfer to an
account in the United States designated by such Holder. All reductions in the
principal amount of a Note (or one or more Predecessor Notes) effected by
payments of principal made on any Payment Date shall be binding upon all Holders
of this Note and of any note issued upon the registration of transfer thereof or
in exchange therefor or in lieu thereof, whether or not such payment is noted on
such Note. The final payment of this Note shall be payable upon presentation and
surrender thereof on or after the Payment Date thereof at the Corporate Trust
Office or the office or agency of the Issuer maintained by it for such purpose
pursuant to Section 3.02 of the Indenture.

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

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

         The failure to pay any Net Monthly Excess Cash Flow at any time when
funds are not available to make such payment as provided in the Indenture shall
not constitute an Event of Default under the Indenture.

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

of any authorized denominations and of a like aggregate initial Note Principal
Balance, will be issued to the designated transferee or transferees.
