together with the Indenture Trustee's certificate of authentication, shall be in

respectively, with such appropriate insertions, omissions, substitutions and
other variations as are required or permitted by this Indenture.

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

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

        Section 2.02 Execution, Authentication and Delivery. The Bonds shall be
executed on behalf of the Issuer by any of its Authorized Officers. The
signature of any such Authorized Officer on the Bonds may be manual or
facsimile.

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

        The Indenture Trustee shall upon Issuer Request authenticate and deliver
the Class 1-A-1, Class 2-A-1 and Class 1-B-1 Bonds for original issue in an

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

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

        Section 2.03 Acceptance of Mortgage Loans by Indenture Trustee. (a) The
Indenture Trustee acknowledges receipt of, subject to the exceptions it notes
pursuant to the procedures described below, the documents (or certified copies
thereof) referred to in Section 2.1(b) of the Mortgage Loan Sale and

                                        4

<PAGE>

Contribution Agreement, and declares that it holds and will continue to hold
those documents and any amendments, replacements or supplements thereto and all
other assets of the Trust Estate as Indenture Trustee in trust for the use and
benefit of all present and future Holders of the Bonds and the Bond Insurer. No
later than 45 days after the Closing Date (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 Bondholders and the Bond Insurer, to review each Mortgage File
delivered to it and to execute and deliver, or cause to be executed and
delivered, to the Seller, the Bond Insurer and the Master Servicer an Initial
Certification in the form annexed hereto as Exhibit C. In conducting such
review, the Indenture Trustee will ascertain whether all required documents
described in Section 2.1(b) of (i) the Mortgage Loan Sale and Contribution
Agreement have been executed and received and whether those documents relate,
determined on the basis of the Mortgagor name, original principal balance and
loan number, to the Mortgage Loans it has received, as identified in Exhibit B
to this Indenture, as supplemented (provided, however, that with respect to
those documents described in subclause (b)(vii) of such section, the Indenture
Trustee's obligations shall extend only to documents actually delivered pursuant
to such subclause). In performing any such review, the Indenture Trustee may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon. If the
Indenture Trustee finds any document constituting part of the Mortgage File not
to have been executed or received, or to be unrelated to the Mortgage Loans
identified in Exhibit B to this Indenture or to appear to be defective on its
face, the Indenture Trustee shall promptly notify the Seller and the Bond
Insurer of such finding and the Seller's obligation to cure such defect or
repurchase or substitute for the related Mortgage Loan. To the extent the
Indenture Trustee has not received a Mortgage File with respect to any of the
Mortgage Loans by the Closing Date, the Indenture Trustee shall not require the
deposit of cash into the Payment Account or any other account to cover the
amount of that Mortgage Loan and shall solely treat such Mortgage Loan as if it
were in breach of a representation or warranty; provided that the aggregate
Stated Principal Balance of such Mortgage Loans does not exceed 1% of the
Cut-off Date Balance.

        (b) No later than 180 days after the Closing Date, the Indenture Trustee
will review, for the benefit of the Bondholders and the Bond Insurer, the
Mortgage Files and will execute and deliver or cause to be executed and
delivered to the Seller and the Bond Insurer, a Final Certification in the form
annexed hereto as Exhibit D. 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 (i) the Mortgage Loan Sale and Contribution
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

                                    Covenants

        Section 3.01 Collection of Payments with respect to the Mortgage Loans.
The Indenture Trustee shall establish and maintain an Eligible Account (the
"Payment Account") in which the Indenture Trustee shall, subject to the terms of
this paragraph, deposit, on the same day as it is received from the Master
Servicer, each remittance received by the Indenture Trustee with respect to the
Mortgage Loans. The Indenture Trustee shall make all payments of principal of
and interest on the Bonds, 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
an office or agency where, subject to satisfaction of conditions set forth
herein, Bonds may be surrendered for registration of transfer or exchange, and
where notices and demands to or upon the Issuer in respect of the Bonds and this
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 may be made at
the office of the Indenture Trustee located at c/o DTC Transfer Services, 55
Water Street, Jeanette Park Entrance, New York, New York 10041, and notices and
demands may be made or served at the Corporate Trust Office, and the Issuer
hereby appoints the Indenture Trustee as its agent to receive all such
surrenders, notices and demands.

        Section 3.03 Money for Payments To Be Held in Trust; Paying Agent. (a)
As provided in Section 3.01, all payments of amounts due and payable with
respect to any Bonds that are to be made from amounts withdrawn from the Payment
Account pursuant to Section 3.01 shall be made on behalf of the Issuer by the
Indenture Trustee or by the Paying Agent, and no amounts so withdrawn from the
Payment Account for payments of Bonds shall be paid over to the Issuer except as
provided in this Section 3.03. The Issuer hereby appoints the Indenture Trustee
as its Paying Agent.

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

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

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

                                        7

<PAGE>

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

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

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

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

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

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

        Section 3.04 Existence. The Issuer will keep in full effect its
existence, rights and franchises as a statutory trust under the laws of the
State of Delaware (unless it becomes, or any successor Issuer

                                        8

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

enforceability of this Indenture, the Bonds, the Mortgage Loans and each other
instrument or agreement included in the Trust Estate.

the Trust Estate.

        (b) The Issuer, with the consent of the Bond Insurer so long as no Bond
Insurer Default exists, may contract with other Persons to assist it in
performing its duties under this Indenture, and any performance of such duties
by a Person identified to the Indenture Trustee in an Officer's Certificate of

        (c) The Issuer will not take any action or permit any action to be taken
by others which would release any Person from any of such Person's covenants or
obligations under any of the documents relating to the Mortgage Loans or under
any instrument included in the Trust Estate, or which would result in the
amendment, hypothecation, subordination, termination or discharge of, or impair
the validity or effectiveness of, any of the documents relating to the Mortgage
Loans or any such instrument, except such actions as the Master Servicer is
expressly permitted to take in the Servicing Agreement. The Indenture Trustee,

        directed to do so by the Indenture Trustee, unless directed to do so by
        the Bond Insurer or the Indenture Trustee with the consent of the Bond
        Insurer, so long as no Bond Insurer Default exists;

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

                      (iii) (A) permit the validity or effectiveness of this
        Indenture to be impaired, or permit the lien of this Indenture to be
        amended, hypothecated, subordinated, terminated or discharged, or permit

        to the Bonds under this Indenture except as may be expressly permitted
        hereby, (B) permit any lien, charge, excise, claim, security interest,
        mortgage or other encumbrance (other than the lien of this Indenture) to

        Estate or any part thereof or any interest therein or the proceeds
        thereof or (C) permit the lien of this Indenture not to constitute a
        valid first priority security interest in the Trust Estate; or

                      (iv) waive or impair, or fail to assert rights under, the
        Mortgage Loans, or impair or cause to be impaired the Issuer's interest
        in the Mortgage Loans, the Mortgage Loan Sale and Contribution Agreement
        or in any Basic Document, if any such action would materially and
        adversely affect the interests of the Bondholders or the Bond Insurer.

        Section 3.10 Annual Statement as to Compliance. The Issuer will deliver
to the Indenture Trustee and the Bond Insurer, by March 1 of each year
commencing with the calendar year 2004, an Officer's Certificate stating, as to
the Authorized Officer signing such Officer's Certificate, that:

                                       15

<PAGE>

                      (i) a review of the activities of the Issuer during the
        previous calendar year and of its performance under this Indenture has
        been made under such Authorized Officer's supervision; and

                      (ii) to the best of such Authorized Officer's knowledge,
        based on such review, the Issuer has complied with all conditions and
        covenants under this Indenture throughout such year, or, if there has
        been a default in its compliance with any such condition or covenant,
        specifying each such default known to such Authorized Officer and the
        nature and status thereof.

        Section 3.11 Representations and Warranties Concerning the Mortgage
Loans. The Indenture Trustee, as pledgee of the Mortgage Loans, has the benefit
of the representations and warranties made by the Seller in the Mortgage Loan
Sale and Contribution Agreement concerning the Seller and the Mortgage Loans to
the same extent as though such representations and warranties were made directly
to the Indenture Trustee. If a Responsible Officer of the Indenture Trustee has
actual knowledge of any breach of any representation or warranty made by the
Seller in the Mortgage Loan Sale and Contribution Agreement, the Indenture
Trustee shall promptly notify the Seller and the Bond Insurer of such finding
and the Seller's obligation to cure such defect or repurchase or substitute for
the related Mortgage Loan.

        Section 3.12 Amendments to Servicing Agreement. The Issuer covenants
with the Indenture Trustee and the Bond Insurer that it will not enter into any
amendment or supplement to the Servicing Agreement without the prior written
consent of the Indenture Trustee and, so long as no Bond Insurer Default exists,
the Bond Insurer.

        Section 3.13 Master Servicer as Agent and Bailee of the Indenture
Trustee. Solely for purposes of perfection under Section 9-305 of the Uniform
Commercial Code or other similar applicable law, rule or regulation of the state
in which such property is held by the Master Servicer, the Issuer and the
Indenture Trustee hereby acknowledge that the Master Servicer is acting as
bailee of the Indenture Trustee in holding amounts on deposit in the Collection
Account, as well as its bailee in holding any Related Documents released to the
Master Servicer, and any other items constituting a part of the Trust Estate
which from time to time come into the possession of the Master Servicer. It is
intended that, by the Master Servicer's acceptance of such bailee arrangement,
the Indenture Trustee, as a secured party of the Mortgage Loans, will be deemed
to have possession of such Related Documents, such monies and such other items
for purposes of Section 9-305 of the Uniform Commercial Code of the state in
which such property is held by the Master Servicer. The Indenture Trustee shall
not be liable with respect to such documents, monies or items while in
possession of the Master Servicer.

        Section 3.14 Investment Company Act. The Issuer shall not become an
"investment company" or be under the "control" of an "investment company" as
such terms are defined in the Investment Company Act of 1940, as amended (or any
successor or amendatory statute), and the rules and regulations thereunder
(taking into account not only the general definition of the term "investment
company" but also any available exceptions to such general definition);
provided, however, that the Issuer shall be in compliance with this Section 3.15
if it shall have obtained an order exempting it from regulation as an
"investment company" so long as it is in compliance with the conditions imposed
in such order.

        In addition, a draw may be made under the Bond Insurance Policy in
respect of any Preference Amount applicable to any of the Class 1-A-1
Bondholders or Class 2-A-1 Bondholders (as defined in and pursuant to the terms
and conditions of the such Bond Insurance Policy) and the Indenture Trustee

accordance with and upon satisfaction of the conditions set forth in the Bond
Insurance Policy, including, without limitation, payment in full of all amounts
owed to the Bond Insurer, may, but shall not be required to, substitute a new
surety bond or surety bonds for the existing Bond Insurance Policy or may
arrange for any other form of credit enhancement; provided, however, that in
each case after giving effect to such substitute or other form of credit
enhancement the Class 1-A-1, Class 2-A-1 and Class 1-B-1 Bonds shall be rated no

2-A-1 and Class 1-B-1 Bonds, respectively, immediately prior to such Replacement
Event and the timing and mechanism for drawing on such new credit enhancement
shall be reasonably acceptable to the Indenture Trustee and provided further
that the premiums under the proposed credit enhancement shall not exceed such
premiums under the existing Bond Insurance Policy. It shall be a condition to
substitution of any new credit enhancement that there be delivered to the
Indenture Trustee (i) an Opinion of Counsel, acceptable in form to the Indenture
Trustee and the Rating Agencies, from counsel to the provider of such new credit
enhancement with respect to the enforceability thereof and such other matters as
the Indenture Trustee and the Rating Agencies may require and (ii) an Opinion of
Counsel to the effect that such substitution would not (a) result in a
"substantial modification" of the Bonds under Treasury Regulation section
1.1001-3, or adversely affect the status of the Bonds as indebtedness for
federal income tax purposes, or (b) if 100% of the Certificates are not owned by
IMH Assets Corp., cause the Trust to be subject to an entity level tax for
federal income tax purposes. Upon receipt of the items referred to above and
payment of all amounts owing to the Bond Insurer and the taking of physical
possession of the new credit enhancement, the Indenture Trustee shall, within
five Business Days following receipt of such items and such taking of physical
possession, deliver the replaced Bond Insurance Policy to the Bond Insurer. In

to the Rating Agencies.

Contracts (a "Derivative Contract Default"), the Issuer, at its expense, may,
but shall not be required to, substitute a new derivative contract for the
existing Derivative Contracts or any other form of similar coverage for basis
risk shortfalls; provided,

however, that the timing and mechanism for receiving payments under such new
derivative contracts shall be reasonably acceptable to the Indenture Trustee. It
shall be a condition to substitution of any new derivative contracts that there
be delivered to the Indenture Trustee an Opinion of Counsel to the effect that
such substitution would not (a) result in a "substantial modification" of the
Bonds under Treasury Regulation section 1.1001-3, or adversely affect the status
of the Bonds as indebtedness for federal income tax purposes, or (b) if 100% of
the Certificates are not owned by IMH Assets Corp., cause the Trust to be
subject to an entity level tax for federal income tax purposes.

        Section 3.30 Allocation of Realized Losses. (a) Prior to each Payment
Date, the Master Servicer shall determine the total amount of Realized Losses
that occurred during the related Prepayment Period. The amount of each Realized
Loss shall be evidenced by an Officer's Certificate delivered to the Indenture
Trustee with the related Remittance Report.

        (b) On each Payment Date following the application of all amounts
distributable on such date, to the extent the aggregate Stated Principal Balance
of the Group 1 Loans is less than the aggregate Bond Principal Balances of the
Class 1-A-1 Bonds and Class 1-B-1 Bonds due to Realized Losses on the Group 1
Loans, the Bond Principal Balances of the Class 1-B-1 Bonds shall be reduced,
until the Bond Principal Balance thereof has been reduced to zero. Any further
losses will be covered by the Bond Insurance Policy in accordance with the terms
thereof, however, to the extent such Realized Losses are not covered by the Bond
Insurance Policy, the Bond Principal Balance of the Class 1-A-1 Bonds will not
be reduced by the amount of such Realized Losses. On each Payment Date following
the application of all amounts distributable on such date, to the extent the
aggregate Stated Principal Balance of the Group 2 Loans is less than the
aggregate Bond Principal Balances of the Class 2-A-1 Bonds due to Realized
Losses on the Group 2 Loans, such losses will be covered by the Bond Insurance
Policy in accordance with the terms thereof, however, to the extent such
Realized Losses are not covered by the Bond Insurance Policy, the Bond Principal
Balance of the Class 2-A-1 Bonds will not be reduced by the amount of such
Realized Losses. All Realized Losses allocated to a Class of Bonds will be
allocated in proportion to the Percentage Interests evidenced thereby.

                                   ARTICLE IV

               The Bonds; Satisfaction and Discharge of Indenture

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

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

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

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

        Section 4.02 Registration of and Limitations on Transfer and Exchange of
Bonds; Appointment of Bond Registrar and Certificate Registrar. The Issuer shall
cause to be kept at the Corporate Trust Office a Bond Register in which, subject
to such reasonable regulations as it may prescribe, the Bond Registrar shall
provide for the registration of Bonds and of transfers and exchanges of Bonds as
herein provided.

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

                                       24

<PAGE>

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

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

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

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

                                       25

<PAGE>

damage, cost or expense incurred by the Issuer, the Bond Insurer or the
Indenture Trustee in connection therewith.

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

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

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

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

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

        Section 4.06 Book-Entry Bonds. The Bonds, upon original issuance, will
be issued in the form of typewritten Bonds representing the Book-Entry Bonds, to
be delivered to The Depository Trust Company, the initial Depository, by, or on
behalf of, the Issuer. The Bonds shall initially be registered on the Bond
Register in the name of Cede & Co., the nominee of the initial Depository, and
no Beneficial

                                       26

<PAGE>

Owner will receive a Definitive Bond representing such Beneficial Owner's
interest in such Bond, except as provided in Section 4.08. With respect to such
Bonds, unless and until definitive, fully registered Bonds (the "Definitive
Bonds") have been issued to Beneficial Owners pursuant to Section 4.08:

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

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

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

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

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

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

        Section 4.08 Definitive Bonds. If (i) the Indenture Trustee determines
that the Depository is no longer willing or able to properly discharge its
responsibilities with respect to the Bonds and the Indenture Trustee is unable
to locate a qualified successor, (ii) the Indenture Trustee elects to terminate
the book- entry system through the Depository or (iii) after the occurrence of
an Event of Default, Beneficial Owners of Bonds representing beneficial
interests aggregating at least a majority of the Bond Principal Balances of the
Bonds 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

                                       27

<PAGE>

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

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

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

               (A) either

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

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

                      a.     have become due and payable,

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

                                       28

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

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

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

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

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

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

        The Indenture Trustee shall, so long as it is indemnified to its
satisfaction, cooperate in all respects with any reasonable written request by
the Bond Insurer (unless a Bond Insurer Default exists) for action

                                       29

<PAGE>

to preserve or enforce the Bond Insurer's rights or interest under this
Indenture or the Insurance Agreement, consistent with this Indenture and without
limiting the rights of the Bondholders as otherwise set forth in the Indenture,
including, without limitation, upon the occurrence and continuance of a default
under the Insurance Agreement, a request to take any one or more of the
following actions:

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

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

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

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

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

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

        Section 4.13 Repayment of Monies Held by Paying Agent. In connection
with the satisfaction and discharge of this Indenture with respect to the Bonds,
all monies then held by any Person other than the Indenture Trustee under the
provisions of this Indenture with respect to such Bonds shall, upon demand of
the Issuer, be paid to the Indenture Trustee to be held and applied according to
Section 3.05 and thereupon such Person shall be released from all further
liability with respect to such monies.

        Section 4.14 Temporary Bonds. Pending the preparation of any Definitive
Bonds, the Issuer may execute and upon its written direction, the Indenture
Trustee may authenticate and make available for delivery, temporary Bonds that
are printed, lithographed, typewritten, photocopied or otherwise produced, in
any denomination, substantially of the tenor of the Definitive Bonds in lieu of
which they are issued and

                                       30

<PAGE>

with such appropriate insertions, omissions, substitutions and other variations
as the officers executing such Bonds may determine, as evidenced by their
execution of such Bonds.

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

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

                                    ARTICLE V

                              Default and Remedies

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

        Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee at the written direction of the Holders of Bonds representing
not less than a majority of the aggregate Bond Principal Balance of the Bonds
may declare the Bonds to be immediately due and payable, by a notice in writing
to the Issuer (and to the Indenture Trustee if such notice is given by
Bondholders), and upon any such declaration the unpaid Bond Principal Balance of
the Class 1-A-1, Class 2-A-1 and Class 1-B-1 Bonds, together with accrued and
unpaid interest thereon through the date of acceleration, shall become
immediately due and payable; provided, however, that for purposes of this
sentence and for purposes of this Article V, unless a Bond Insurer Default
exists, the Bond Insurer may exercise the rights of all of the Holders of the
Class 1-A-1 Bonds and Class 2-A-1 Bonds.

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

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

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

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

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

                                       32

<PAGE>

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

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

        Section 5.03 Collection of Indebtedness and Suits for Enforcement by
Indenture Trustee.

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

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

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

        (d) In case there shall be pending, relative to the Issuer or any other
obligor upon the Bonds or any Person having or claiming an ownership interest in
the Trust Estate, Proceedings under Title 11 of the United States Code or any
other applicable federal or state bankruptcy, insolvency or other similar law,
or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or
taken possession of the Issuer or its property or such other obligor

                                       33

<PAGE>

or Person, or in case of any other comparable judicial Proceedings relative to
the Issuer or other obligor upon the Bonds, or to the creditors or property of
the Issuer or such other obligor, the Indenture Trustee, at the direction of the
Bond Insurer, so long as no Bond Insurer Default exists, irrespective of whether
the principal of any Bonds shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Indenture Trustee
shall have made any demand pursuant to the provisions of this Section, shall be
entitled and empowered, by intervention in such Proceedings or otherwise:

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

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

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

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

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

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

                                       34

<PAGE>

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

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

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

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

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

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

                      (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 so long as a Bond Insurer Default exists the Indenture
Trustee may not sell or otherwise liquidate the Trust Estate following an Event
of Default, unless (A) the Indenture Trustee obtains the consent of the Holders
of 100% of the aggregate Bond Principal Balance to discharge in full all amounts
then due and unpaid upon the Bonds for principal and interest and to reimburse
the Bond Insurer for any amounts drawn under the Bond Insurance Policy and any
other amounts due to the Bond Insurer under the Insurance Agreement or (C) the
Indenture Trustee determines that the Mortgage Loans will not continue to
provide sufficient funds for the payment of principal of and interest on the
Bonds as they would have

                                       35

<PAGE>

become due if the Bonds had not been declared due and payable, and the Indenture
Trustee obtains the consent of the Holders of a majority of the aggregate Bond
Principal Balance of the Class 1-A-1, Class 2-A-1 and Class 1-B-1 Bonds. In
determining such sufficiency or insufficiency with respect to clause (B) and
(C), the Indenture Trustee may, but need not, obtain and rely upon an opinion
(obtained at the expense of the Trust) of an Independent investment banking or
accounting firm of national reputation as to the feasibility of such proposed
action and as to the sufficiency of the Trust Estate for such purpose.
Notwithstanding the foregoing, so long as an Event of Servicer Termination has
not occurred, any Sale of the Trust Estate shall be made subject to the
continued servicing of the Mortgage Loans by the Master Servicer as provided in
the Servicing Agreement.

        (b) If the Indenture Trustee collects any money or property pursuant to
this Article V, it shall pay out the money or property in the following order;
provided, however, that any amounts representing payments from the Bond Insurer
shall only be used to pay interest and principal to the Class 1-A-1 Bondholders
and Class 2-A-1 Bondholders pursuant to clauses FOURTH and FIFTH below:

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

               SECOND: to the Derivative Contract Counterparty, any amounts
        owed under the Derivative Contracts, other than any Additional
        Derivative Counterparty Payment;

               THIRD: to the Bond Insurer, provided no Bond Insurer Default
        exists, with respect to any Premium Amount then due to the extent unpaid
        pursuant to the Servicing Agreement;

               FOURTH: to the Bondholders for amounts due and unpaid on the
        Bonds (other than Unpaid Interest Shortfalls and Basis Risk Shortfall
        Carry-Forward Amounts) with respect to interest, first, to the Class
        1-A-1 Bondholders and Class 2-A-1 Bondholders, concurrently, and second,
        to the Class 1-B-1 Bondholders, according to the amounts due and payable
        on the Bonds for interest;

               FIFTH: to Bondholders for amounts due and unpaid on the Class
        1-A-1, Class 2-A-1 and Class 1-B-1 Bonds with respect to principal, and
        to each Bondholder ratably, without preference or priority of any kind,
        according to the amounts due and payable on such Bonds for principal,
        until the Bond Principal Balance of each such Class is reduced to zero;

               SIXTH: to the payment of all amounts due and owing to the Bond
        Insurer under the Insurance Agreement (including any Premium Amount not
        paid pursuant to clause SECOND above);

               SEVENTH: to the Bondholders for amounts due and unpaid on the
        Bonds with respect to any related Basis Risk Shortfall Carry-Forward
        Amounts, first, to the Class 1-A-1 Bondholders and Class 2-A-1
        Bondholders, concurrently, and second, to the Class 1-B-1 Bondholders,
        according to the amounts due and payable on the Bonds with respect
        thereto, from amounts available in the Trust Estate for the Bondholders;

                                       36

<PAGE>

               EIGHTH: to the Bondholders for amounts due and unpaid on the
        Bonds with respect to any related Unpaid Interest Shortfall, first, to
        the Class 1-A-1 Bondholders and Class 2-A-1 Bondholders, concurrently,
        and second, to the Class 1-B-1 Bondholders, according to the amounts due
        and payable on the Bonds with respect thereto, from amounts available in
        the Trust Estate for the Bondholders; and

               NINTH: to the Derivative Contract Counterparty, any Additional
        Derivative Counterparty Payment; and

               TENTH: to the payment of the remainder, if any to the
        Certificate Paying Agent on behalf of the Issuer or to any other person
        legally entitled thereto.

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

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

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

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

                      (ii) the Holders of not less than 25% of the aggregate
        Bond Principal Balances of the Bonds 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;

                                       37

<PAGE>

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

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

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

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

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

        Subject to the last paragraph of Section 5.11 herein, in the event the
Indenture Trustee shall receive conflicting or inconsistent requests and
indemnity from two or more groups of Holders of Bonds, each representing less
than a majority of the Bond Principal Balances of the Bonds, the Indenture
Trustee in its sole discretion may determine what action, if any, shall be
taken, notwithstanding any other provisions of this Indenture.

        Section 5.07 Unconditional Rights of Bondholders To Receive Principal
and Interest. Notwithstanding any other provisions in this Indenture, the Holder
of any Bond shall have the right, which is absolute and unconditional, to
receive payment of the principal of and interest, if any, on such Bond on or
after the respective due dates thereof expressed in such Bond or in this
Indenture and to institute suit for the enforcement of any such payment, and
such right shall not be impaired without the consent of such Holder.

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

        Section 5.09 Rights and Remedies Cumulative. No right or remedy herein
conferred upon or reserved to the Indenture Trustee, to the Bond Insurer or to
the Bondholders is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be

                                       38

<PAGE>

cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

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

        Section 5.11 Control By Bond Insurer. The Bond Insurer, unless a Bond
Insurer Default exists, or the Holders of a majority of the aggregate Bond
Principal Balances of Bonds, if a Bond Insurer Default exists, shall have the
right (subject to the provisions of Section 5.06) to direct the time, method and
place of conducting any Proceeding for any remedy available to the Indenture
Trustee with respect to the Bonds or exercising any trust or power conferred on
the Indenture Trustee; provided that:

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

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

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

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

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

        Section 5.12 Waiver of Past Defaults. Prior to the declaration of the
acceleration of the maturity of the Bonds as provided in Section 5.02 hereof,
the Holders of Bonds representing not less than a majority of the aggregate Bond
Principal Balance of the Bonds 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

                                       39

<PAGE>

the Bonds, (b) in respect of a covenant or provision hereof which cannot be
modified or amended without the consent of the Holder of each Bond or (c) the
waiver of which would materially and adversely affect the interests of the Bond
Insurer or modify its obligation under the Bond Insurance Policy. In the case of
any such waiver, the Issuer, the Indenture Trustee and the Holders of the Bonds
shall be restored to their former positions and rights hereunder, respectively,
but no such waiver shall extend to any subsequent or other Event of Default or
impair any right consequent thereto.

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

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

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

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

                                       40

<PAGE>

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

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

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

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

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

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

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

               (1) any Holder or Holders of Bonds may bid for and purchase the
        property offered for sale, and upon compliance with the terms of sale
        may hold, retain and possess and dispose of such property, without
        further accountability, and may, in paying the purchase money therefor,
        deliver any Bonds or claims for interest thereon in lieu of cash up to
        the amount which shall, upon distribution of the net proceeds of such
        sale, be payable thereon, and such Bonds, 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, with the consent of the Bond Insurer
        so long as no Bond Insurer Default exists, may bid for and acquire the
        property offered for Sale in connection with any Sale thereof, and,
        subject to any requirements of, and to the extent permitted by,
        applicable law

                                       41

<PAGE>

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

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

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

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

        Section 5.17 Performance and Enforcement of Certain Obligations. (a)
Promptly following a request from the Indenture Trustee to do so, the Issuer in
its capacity as holder of the Mortgage Loans, shall take all such lawful action
as the Indenture Trustee or the Bond Insurer may request to cause the Issuer to
compel or secure the performance and observance by the Seller and the Master
Servicer, as applicable, of each of their obligations to the Issuer under or in
connection with the Mortgage Loan Sale and Contribution Agreement 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 Sale and Contribution Agreement and the Servicing Agreement to the
extent and in the manner directed by the Indenture Trustee, with the consent of
the Bond Insurer so long as no Bond Insurer Default exists, 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

                                       42

<PAGE>

Mortgage Loan Sale and Contribution Agreement and the Servicing Agreement. So
long as no Bond Insurer Default exists, the Bond Insurer shall have the right to
approve or reject any proposed successor to the Master Servicer (other than the
Indenture Trustee) under the Servicing Agreement.

        (b) The Indenture Trustee, as pledgee of the Mortgage Loans, subject to
the rights of the Bond Insurer under this Agreement and the Servicing Agreement,
may, and at the direction (which direction shall be in writing or by telephone
(confirmed in writing promptly thereafter)) of the Bond Insurer or if a Bond
Insurer Default exists, of the Holders of 66-2/3% of the Bond Principal Balances
of the Bonds, shall exercise all rights, remedies, powers, privileges and claims
of the Issuer against the Seller or the Master Servicer under or in connection
with the Mortgage Loan Sale and Contribution Agreement 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 Sale and Contribution Agreement and Contribution Agreement and the
Servicing Agreement, as the case may be, and any right of the Issuer to take
such action shall not be suspended.

                                   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
        respect to any action it takes or omits to take in good faith in
        accordance with a direction received by it (A) from Bondholders or from
        the Issuer, which they are entitled to give under the Basic Documents or
        (B) from the Bond Insurer, which it is entitled to give under the Basic
        Documents.

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

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

                                       44

<PAGE>

        (f) No provision of this Indenture shall require the Indenture Trustee
to expend or risk its own funds or otherwise incur financial liability in the
performance of any of its duties hereunder or in the exercise of any of its
rights or powers, if it shall have reasonable grounds to believe that repayment
of such funds or adequate indemnity against such risk or liability is not
reasonably assured to it.

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

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

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

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

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

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

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

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

        (g) The Indenture Trustee or its Affiliates are permitted to receive
additional compensation that could be deemed to be in the Indenture Trustee's
economic self-interest for (i) serving as investment adviser, administrator,
shareholder servicing agent, custodian or sub-custodian with respect to certain
of the Eligible Investments, (ii) using Affiliates to effect transactions in
certain Eligible Investments and (iii)

                                       45

<PAGE>

effecting transactions in certain Eligible Investments. Such compensation shall
not be considered an amount that is reimbursable or payable to the Indenture
Trustee (i) as part of the Indenture Trustee Fee, (ii) pursuant to Sections
3.05(d), 3.05(h), 5.04(b), 6.07 or 8.02(c) hereunder or (iii) out of Available
Funds.

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

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

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

        Section 6.06 Reports by Indenture Trustee to Holders and Tax
Administration. The Indenture Trustee shall deliver to each Bondholder such
information as may be required to enable such holder to prepare its federal and
state income tax returns.

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

        Section 6.07 Compensation and Indemnity. The Issuer shall pay to the
Indenture Trustee on each Payment Date reasonable compensation for its services.
The amount of the Indenture Trustee's Fee shall be paid by the Master Servicer
to the Indenture Trustee on each Payment Date pursuant to Section 3.07(a)(x) of
the Servicing Agreement and all amounts owing to the Indenture Trustee hereunder
(including amounts owing from the Issuer for indemnification and otherwise) in
excess of such amount shall be paid solely as provided in Section 3.05(d)(ix),
Section 3.05(h)(viii) and Section 5.04(b) hereof. The Indenture Trustee's
compensation shall not be limited by any law on compensation of a trustee of an
express trust. The Issuer shall reimburse the Indenture Trustee for all
reasonable out-of-pocket expenses incurred or made by it, including costs of
collection, in addition to compensation for its services. Such expenses shall

                                       46

<PAGE>

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,
negligence or bad faith.

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

        Section 6.08 Replacement of Indenture Trustee. No resignation or removal
of the Indenture Trustee and no appointment of a successor Indenture Trustee
shall become effective until the acceptance of appointment by the successor
Indenture Trustee pursuant to this Section 6.08. The Indenture Trustee may
resign at any time by so notifying the Issuer and the Bond Insurer. The Bond
Insurer or, if a Bond Insurer Default exists, the Holders of a majority of Bond
Principal Balances of the Bonds may remove the Indenture Trustee by so notifying
the Indenture Trustee and the Bond Insurer and may appoint a successor Indenture
Trustee. The Issuer shall, with the consent of the Bond Insurer so long as no
Bond Insurer Default exists, remove the Indenture Trustee if:

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

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

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

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

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

        A successor Indenture Trustee shall deliver a written acceptance of its
appointment to the retiring Indenture Trustee, to the Bond Insurer and to the
Issuer. Thereupon, the resignation or removal of the retiring Indenture Trustee
shall become effective, and the successor Indenture Trustee shall have all the

                                       47

<PAGE>

rights, powers and duties of the Indenture Trustee under this Indenture. The
successor Indenture Trustee shall mail a notice of its succession to
Bondholders. The retiring Indenture Trustee shall promptly transfer all property
held by it as Indenture Trustee to the successor Indenture Trustee.

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

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

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

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

        Section 6.10 Appointment of Co-Indenture Trustee or Separate Indenture
Trustee. (a) Notwithstanding any other provisions of this Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the Trust Estate may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to

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

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

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

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

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

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

principal and interest on the Bonds in accordance with Section 3.05(b) and (c)
hereof and payment in full to the Bond Insurer for all amounts owing under the
Insurance Agreement and the Indenture Trustee, and this Indenture shall be
discharged subject to the provisions of Section 4.10 hereof. If for any reason
the amount deposited by the 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 Bondholders. (a)
Without the consent of the Holders of any Bonds but with the prior written
consent of the Bond Insurer and prior notice to the Rating Agencies and the Bond
Insurer, 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 Bonds contained;

                      (iii) to add to the covenants of the Issuer, for the
        benefit of the Holders of the Bonds, 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 Bonds;

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

                                       59

<PAGE>

provided, however, that no such indenture supplements shall be entered into
unless the Indenture Trustee shall have received an Opinion of Counsel as to the
enforceability of any such indenture supplement and to the effect that (i) such
indenture supplement is permitted hereunder and (ii) entering into such
indenture supplement will not result in a "substantial modification" of the
Bonds under Treasury Regulation Section 1.1001-3 or adversely affect the status
of the Bonds 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 Bonds but
with the prior written consent of the Bond Insurer and prior notice to the
Rating Agencies and the Bond Insurer, 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 Bonds under this
Indenture; provided, however, that such action as evidenced by an Opinion of
Counsel, (i) is permitted by this Indenture, and shall not (ii) adversely affect
in any material respect the interests of any Bondholder or (iii) if 100% of the
Certificates are not owned by IMH 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 Bondholders. The
Issuer and the Indenture Trustee, when authorized by an Issuer Request, also
may, with prior notice to the Rating Agencies and, with the prior written
consent of the Bond Insurer and with the consent of the Holders of not less than
a majority of the Bond Principal Balance of each Class of Bonds 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 Bonds under this
Indenture; provided, however, that no such supplemental indenture shall, without
the consent of the Holder of each Bond affected thereby:

                      (i) change the date of payment of any installment of
        principal of or interest on any Bond, 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 Bonds, or change any place of payment where, or the coin or
        currency in which, any Bond 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
        Bonds on or after the respective due dates thereof;

                      (ii) reduce the percentage of the Bond Principal Balances
        of the Bonds, 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;

                                       60

<PAGE>

                      (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 Bond Principal Balances
        of the Bonds 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 Bond
        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 Bond 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 Bond of the security
        provided by the lien of this Indenture;

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

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

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

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

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

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

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

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

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

                                    ARTICLE X

                                  Miscellaneous

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

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

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

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

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

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

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

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

                      (ii) Whenever the Issuer is required to furnish to the
        Indenture Trustee and the Bond Insurer an Officer's Certificate
        certifying or stating the opinion of any signer thereof as to the
        matters described in clause (i) above, the Issuer shall also deliver to
        the Indenture Trustee an

                                       63

<PAGE>

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

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

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

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

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

                                       64

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

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

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

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

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

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

        Section 10.04 Notices etc., to Indenture Trustee Issuer and Rating
Agencies. Any request, demand, authorization, direction, notice, consent, waiver
or Act of Bondholders or other documents provided or permitted by this Indenture
shall be in writing and if such request, demand, authorization, direction,
notice, consent, waiver or act of Bondholders is to be made upon, given or
furnished to or filed with:

                                       65

<PAGE>

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

                      (ii) the Issuer by the Indenture Trustee or by any
        Bondholder shall be sufficient for every purpose hereunder if in writing
        and mailed first-class, postage prepaid to the Issuer addressed to:
        Impac CMB Trust Series 2003-1, in care of Wilmington Trust Company,
        Rodney Square North, 1100 North Market Street, Wilmington, Delaware
        19990-0001, Attention: Corporate Trust Administration, or at any other
        address previously furnished in writing to the Indenture Trustee by the
        Issuer. The Issuer shall promptly transmit any notice received by it
        from the Bondholders to the Indenture Trustee; or

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

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

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

        Where this Indenture provides for notice in any manner, such notice may
be waived in writing by any Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by Bondholders shall be filed with the Indenture
Trustee but

                                       66

<PAGE>

such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such a waiver.

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

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

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

        The provisions of TIA ss.ss. 310 through 317 that impose duties on any

this Indenture shall bind its successors, co-trustees and agents.

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

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

        Section 10.11 Legal Holidays. In any case where the date on which any
payment is due shall not be a Business Day, then (notwithstanding any other
provision of the Bonds or this Indenture) payment need not be made on such date,
but may be made on the next succeeding Business Day with the same force and

                                       67

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

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

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

        Section 10.15 Issuer Obligation. No recourse may be taken, directly or

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

such disclosure is consistent with its obligations hereunder.

        Impac CMB Trust Series 2003-1 (the "Issuer"), a Delaware statutory
trust, for value received, hereby promises to pay to Cede & Co. or registered
assigns, the principal sum of ($_________________) in monthly installments on
the twenty-fifth day of each month or, if such day is not a Business Day, the
next succeeding Business Day (each a "Payment Date"), commencing in February
2003 and ending on or before the Payment Date occurring in March 2033 (the
"Final Scheduled Payment Date") and to pay interest on the Bond Principal
Balance of this Bond (this "Bond") outstanding from time to time as provided
below.

        This Bond is one of a duly authorized issue of the Issuer's
Collateralized Asset-Backed Bonds, Series 2003-1 (the "Bonds"), issued under an
Indenture dated as of January 30, 2003 (the "Indenture"), between the Issuer and
Deutsche Bank National Trust Company, as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee, and the Holders of the Bonds and the terms upon
which the Bonds are to be authenticated and delivered. All terms used in this
Bond which are defined in the Indenture shall have the meanings assigned to them
in the Indenture.

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

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

                                      A-1-2

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

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

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

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

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

                                      A-1-3

<PAGE>

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

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

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

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

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

                                      A-1-4

<PAGE>

discretion, including actions relating to the occurrence of, and the remedies
with respect to, an Event of Default, only at the direction, or with the
consent, of the Bond Insurer.

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

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

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

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

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

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

        Impac CMB Trust Series 2003-1 (the "Issuer"), a Delaware statutory
trust, for value received, hereby promises to pay to Cede & Co. or registered
assigns, the principal sum of ______________________________ ($___________) in
monthly installments on the twenty-fifth day of each month or, if such day is
not a Business Day, the next succeeding Business Day (each a "Payment Date"),
commencing in February 2003 and ending on or before the Payment Date occurring
in March 2033 (the "Final Scheduled Payment Date") and to pay interest on the
Bond Principal Balance of this Bond (this "Bond") outstanding from time to time
as provided below.

        This Bond is one of a duly authorized issue of the Issuer's
Collateralized Asset-Backed Bonds, Series 2003-1 (the "Bonds"), issued under an
Indenture dated as of January 30, 2003 (the "Indenture"), between the Issuer and
Deutsche Bank National Trust Company, as indenture trustee (the "Indenture
Trustee", which term includes any successor Indenture Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto reference
is hereby made for a statement of the respective rights thereunder of the
Issuer, the Indenture Trustee, and the Holders of the Bonds and the terms upon
which the Bonds are to be authenticated and delivered. All terms used in this
Bond which are defined in the Indenture shall have the meanings assigned to them
in the Indenture.

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

        The principal of, and interest on, this Bond are due and payable as
described in the Indenture, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts. All payments made by the Issuer with respect to this Bond shall
be equal to this Bond's pro rata share of the aggregate payments on all Class
1-B-1 Bonds as described above, and shall be applied as between interest and
principal as provided in the Indenture.

                                      A-2-2

<PAGE>

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

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

        The Issuer shall not be liable upon the indebtedness evidenced by the
Bonds except to the extent of amounts available from the Trust Estate which
constitutes security for the payment of the Bonds. The assets included in the
Trust Estate will be the sole source of payments on the Class 1-B-1 Bonds, and
each Holder hereof, by its acceptance of this Bond, agrees that (i) such Bond
will be limited in right of payment to amounts available from the Trust Estate
as provided in the Indenture and (ii) such Holder shall have no recourse to the
Issuer, the Owner Trustee, the Indenture Trustee, IMH Assets Corp., Impac
Mortgage Holdings, Inc., the Master Servicer or any of their respective
affiliates, or to the assets of any of the foregoing entities, except the assets
of the Issuer pledged to secure the Class 1-B-1 Bonds pursuant to the Indenture
and the rights conveyed to the Issuer under the Indenture.

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

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

        If an Event of Default as defined in the Indenture shall occur and be
continuing with respect to the Bonds, the Bonds may become or be declared due
and payable in the manner and with the effect provided in the Indenture. If any
such acceleration of maturity occurs prior to the payment of the entire unpaid
Bond Principal Balance of the Bonds, the amount payable to the Holder of this
Bond will be equal to the sum of the unpaid Bond Principal Balance of the Bonds,
together with accrued and unpaid interest thereon as

                                      A-2-3

<PAGE>

described in the Indenture. The Indenture provides that, notwithstanding the
acceleration of the maturity of the Bonds, under certain circumstances specified
therein, all amounts collected as proceeds of the Trust Estate securing the
Bonds or otherwise shall continue to be applied to payments of principal of and
interest on the Bonds as if they had not been declared due and payable.

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

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

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

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

        The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the Bonds under the

                                      A-2-4

<PAGE>

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

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

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

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

                Series 2003- 1 and Deutsche Bank National Trust Company

Ladies and Gentlemen:

               In accordance with Section 2.03(a) of the above-captioned
Indenture, and Section 2.1(b)(i)-(v) of the Mortgage Loan Sale and Contribution
Agreement, dated as of January 30, 2003 between Impac Mortgage Holdings, Inc.
and Impac Funding Corporation (the "MLSCA"; and together with the Indenture, the
"Agreements"), the undersigned, as Indenture Trustee, hereby certifies that as
to each Mortgage Loan listed in the Mortgage Loan Schedule (other than any
Mortgage Loan paid in full or listed on the exception report attached hereto) it
has reviewed the Mortgage File and the Mortgage Loan Schedule and has determined
that: (i) all documents required to be included in the Mortgage File are in its
possession; (ii) such documents have been reviewed by it and appear regular on
their face and relate to such Mortgage Loan; and (iii) based on examination by
it, and only as to such documents, the information set forth in items (iii) and
(v) of the definition or description of "Mortgage Loan Schedule" is correct.

               The Indenture Trustee has made no independent examination of any
documents contained in each Mortgage File beyond the review specifically
required in the above-referenced Agreements. The Indenture Trustee makes no
representation that any documents specified in clause (v) of Section 2.1 (b) of
the MLSCA should be included in any Mortgage File. The Indenture Trustee makes
no representations as to and shall not be responsible to verify: (i) the
validity, legality, sufficiency, enforceability, due authorization,
recordability or genuineness of any of the documents contained in each Mortgage
File of any of the Mortgage Loans identified on the Mortgage Loan Schedule, (ii)
the collectability, insurability, effectiveness or suitability of any such
Mortgage Loan, or (iii) the existence of any assumption, modification, written
assurance or substitution agreement with respect to any Mortgage File if no such
documents appear in the Mortgage File delivered to the Indenture Trustee.

confusion.

Territory (such as, for example, any activity which may be considered by a
competent court to infringe a Patent Right owned by a Third Party), and Elan
shall be responsible for obtaining any rights or licenses to Third Party
Intellectual Property required for the manufacture, sale, offer for sale, use,
promotion, import or export of the Product or any Elan Improvement outside of
the Territory. Each of Enzon and Elan shall provide prompt written notice to the
other of the particulars of any Third Party Intellectual

by or granted hereunder shall be freely sublicensable by the licensee, its
Affiliates and their respective licensees, sublicensees or contracting parties

days following the Closing Date, the parties shall agree on a schedule for the
comprehensive disclosure by Elan to Enzon of all Product Know-How. Elan shall

qualified and knowledgeable personnel to promptly respond to reasonable
questions pertaining to Product Know-How. Elan will make its personnel available
for up to 100 hours without additional charge, and for up to an additional two
hundred (200) hours at an hourly rate agreed upon by the parties. Upon the
expiration of the Transfer Period, Elan shall have no further transfer
obligations.

                                    ARTICLE 3

                           MAINTENANCE AND ENFORCEMENT
                         OF INTELLECTUAL PROPERTY RIGHTS

            Section 3.01. Prosecution and Maintenance of Patent Rights.

            (a) Decisions as to whether to file, prosecute and maintain, the
Product Specific Patent Rights, along with other strategic decisions relating to
patent prosecution thereof in the Territory, shall be made by Enzon, at Enzon's
sole expense and discretion. Elan shall coordinate and cooperate in the filing,
maintenance or prosecution of the Product Specific Patent Rights with the person
or persons designated in writing by Enzon. Enzon shall reasonably advise Elan of
the status and prosecution strategy of the actual and prospective patent
filings. Enzon shall not materially prejudice any foreign counterparts of the
Product Specific Patent Rights. Elan shall be permitted to comment on the
prosecution of the Patent Rights subject to this Section 3.01(a) and may, at
its own expense and

                                       -6-

<PAGE>

discretion, submit such comments to Enzon. Enzon shall consider such comments in
good faith, but shall not be obligated to implement them.

            (b) Decisions as to whether to file, prosecute and maintain, the
Product Related Patent Rights or the foreign counterparts of the Product Patent
Rights, along with other strategic decisions relating to patent prosecution
thereof, shall be made by Elan, at Elan's sole expense and discretion. Enzon
shall coordinate and cooperate in the filing, maintenance or prosecution of the
Product Related Patent Rights with the person or persons designated in writing
by Elan; provided, however, that to the extent such activities are unrelated to
the Product or any Product Improvement, Enzon shall be reimbursed for its
reasonable out-of-pocket costs relating thereto. Elan shall reasonably advise
Enzon of the status and prosecution strategy of the actual and prospective
patent filings in the Territory. Elan shall not materially prejudice the Product
Patent Rights. Enzon shall be permitted to comment on the prosecution of the
Patent Rights subject to this Section 3.01(b) and may, at its own expense and
discretion, submit such comments to Elan. Elan shall consider such comments in
good faith, but shall not be obligated to implement them.

            (c) Immediately upon the decision of either party not to file,
maintain or continue the prosecution of any Product Patent Rights or foreign
counterparts thereof, and at least sixty (60) days before ceasing prosecution
and/or maintenance of any such Patent Rights, if a party elects not to file a
patent application or ceases the diligent prosecution and/or maintenance of any
such Patent Right, the other party at its sole discretion, may elect to file
and/or continue prosecution and/or maintenance or assume control of the
prosecution of such Patent Rights at its own cost and expense.

            (d) The parties shall cooperate, if necessary and appropriate, with
each other in gaining patent term extensions that are now available or become
available in the future wherever applicable to the Product, a Product
Improvement or an Elan Improvement. The parties shall, if necessary and
appropriate, use reasonable efforts to agree upon a joint strategy relating to
patent term extensions, but, in the absence of mutual agreement with respect to
any extension issue, a patent shall be extended if either party elects to extend
such patent. All filings for such extension shall be made by the party to whom
the patent is assigned; provided, however, such party shall (i) inform the other
party of its intention not to file and (ii) grant the other party the right to
file for such extension.

            (e) Except as otherwise provided for by the Asset Purchase Agreement
or the Supply Agreement, the parties shall bear their own costs and expenses of
filing, prosecuting, maintaining and extending any Patent Rights subject to this
Agreement.

            Section 3.02. Infringement of Licensed Property.

            (a) Enzon shall, with respect to infringement claims maturing after
the Effective Date, within the Territory, have the sole and exclusive right to
enforce, even as to acts or products unrelated to the Product or any Product
Improvement (a "Non-Product Claim"), the Patent Specific Product Rights. Elan
shall, within and without the Territory, have and retain the sole and exclusive
right to enforce, even as to acts or products related to the Product or any
Product Improvement (a "Product Related Claim") of the Patent Related Product
Rights and the foreign counterparts of the Product Patent Rights. In
prosecuting, as applicable, the enforcement rights retained or granted under

                                       -7-

<PAGE>

this Section 3.02(a), neither party may materially prejudice the other party's
rights, as applicable, in the Product Patent Rights or their foreign
counterparts. The parties agree to cooperate in the enforcement of the Product
Patent Rights. If one party brings any action or proceeding to enforce the
Product Patent Rights, the second party may be joined as a party plaintiff if
necessary for the action or proceeding to proceed and, in case of joining, the
second party agrees to give the first party reasonable assistance and authority
to file and to prosecute such suit. Each party agrees to provide the party that
is seeking to prevent or enjoin any such infringement with all reasonable
assistance, information and authority to perform the foregoing. The
non-prosecuting party shall have the right, but not the obligation at its own
expense, to be represented in such action by its own counsel. Each party shall
keep the other party reasonably informed as to the status and conduct of the
litigation and shall, at the other party's sole cost and expense, accept and
reasonably consider the other party's comments relating thereto. A party having
knowledge that any of the Product Patent Rights are subject to infringement, or
having knowledge of a reasonable probability of such infringement, shall
promptly notify the other in writing, but in any event within thirty (30) days
of receipt of written notice of such infringement. The notice shall set forth
the facts of such infringement in reasonable detail.

            (b) Upon receiving notice of infringement or suspected infringement
of the Product Specific Patent Rights, including, without limitation, a
Non-Product Claim, Enzon shall have the sole right and discretion, but not the
obligation, to institute, prosecute, and control with its own counsel at its own
expense any action or proceeding with respect to infringement of the Product
Specific Patents and Elan shall have the right, but not the obligation at its
own expense, to be represented in such action by its own counsel. Enzon shall be
entitled to retain all awards, damages and settlement amounts arising out of any
action initiated pursuant to this Section 3.02(b); provided, however, Elan shall
be entitled to receive fifty percent (50%) of any amount directly attributable
to any Non-Product Claim less Enzon's reasonable attorneys' fees and expenses
relating to prosecuting such Non-Product Claim. Elan shall have no right to
institute or prosecute such an infringement action if Enzon declines to do so.

            (c) Upon receiving notice of infringement or suspected infringement
of the Product Related Patent Rights or the foreign counterparts of the Product
Patent Rights, including, without limitation, a Product Related Claim, Elan
shall have the sole right and discretion, but not the obligation, to institute,
prosecute, and control with its own counsel at its own expense any action or
proceeding with respect to infringement of the Product Related Patent Rights or
the foreign counterparts of the Product Patent Rights and Enzon shall have the
right, but not the obligation at its own expense, to be represented in such
action by its own counsel. Elan shall be entitled to retain all awards, damages
and settlement amounts arising out of any action initiated pursuant to this
Section 3.02(b); provided, however, Enzon shall be entitled to receive fifty
percent (50%) of any amount directly attributable to any Product Related Claim
arising out of the Product Related Patent Rights less Elan's reasonable
attorneys' fees and expenses relating to prosecuting such Product Related Claim.
Enzon shall have no right to institute such an infringement action if Elan to do
so.

            Section 3.03. Challenge of Patents. Neither party or its Affiliates,
nor their respective sublicensees, will challenge (other than in defense of an
action for infringement of a Product Patent Right or in an action for breach of
contract) any of the Patent Rights owned or Controlled by the other party or its
Affiliates that are related to the Product, or to any Product Improvement in the

                                       -8-

<PAGE>

case of Enzon and any Elan Improvement in the case of Elan, or support an action
of its Affiliate or a Third Party challenging the validity of any such Patent
Rights.

                                    ARTICLE 4

                              TERM AND TERMINATION

            Section 4.01. Term and Expiration. This Agreement shall become
effective as of the Effective Date and shall continue in perpetuity unless and
until all licenses under Section 2 have terminated by mutual written agreement
of the parties.

            Section 4.02. Accrued Rights; Surviving Obligations. Termination of
this Agreement shall be without prejudice to any rights that shall have accrued
to the benefit of any party prior to such termination. Such termination shall
not relieve any party from obligations that are expressly indicated to survive
termination of this Agreement.

                                    ARTICLE 5

                                  MISCELLANEOUS

            Section 5.01. Assignment, Binding Effect. Neither Elan nor Enzon may
assign this agreement, or any of their respective right or obligations
hereunder, without the prior written consent of the other party, which consent
shall not be unreasonably withheld; provided, however, that (i) either party may
assign this Agreement to an Affiliate without the prior written consent of the
other party, and (ii) either party may assign or transfer this Agreement without
consent to any entity into or with which such party merges or consolidates, or
to whom such party transfers all or substantially all of its business or assets
to which this Agreement relates, subject in either case to the assignee or
transferee agreeing in advance and in writing to assume all of the assignor's or
transferor's obligations under this Agreement. Notwithstanding the foregoing,
the Product Patent Rights may not be assigned to an Affiliate or a Third Party
without the concomitant assignment of this Agreement or all of the obligations
hereunder to the assignee and any attempt to do so will be null and void. This
Agreement is binding upon, inures to the benefit of and is enforceable by the
parties hereto and each of their respective successors and permitted assigns.
The covenants, licenses and obligations contained herein are appurtenant to and
shall run with transfer, assignment, sale or other disposition of the Patent
Rights subject to this Agreement. Each party, at the request of the other party,
shall take such reasonable steps, including, without limitation, filings with
the applicable patent office, as are necessary to perfect the other party's
rights with respect to such Patent Rights under this Agreement.

            Section 5.02. Insolvency. All rights and licenses granted under or
pursuant to this Agreement by either party are, and shall otherwise be deemed to
be, for purposes of Section 365(n) of the U.S. Bankruptcy Code and other similar
foreign laws, licenses of rights to "intellectual property" as defined under
Section 101 of the U.S. Bankruptcy Code or such foreign laws. Each party

                                       -9-

<PAGE>

agrees that the other party, as a licensee of such rights under this Agreement,
shall retain and may fully exercise all of its rights and elections under
Section 365(n) of the U.S. Bankruptcy Code and other similar foreign laws, and
neither party shall claim that this Agreement does not fall within the scope
thereof. Each party further agrees that, upon the commencement of a bankruptcy
proceeding by or against such party under the U.S. Bankruptcy Code, the other
party shall be immediately entitled to a complete duplicate of (or complete
access to, as appropriate) any such intellectual property and all embodiments of
such intellectual property, and the same, if not already in such other party's
possession, shall be promptly delivered to the other party if such party rejects
this Agreement, fails to promptly elect in writing to continue to perform all of
its obligations under this Agreement, and/or fails to take all steps necessary
to protect such intellectual property.

            Section 5.03. Tax Matters. Elan agrees that it will deliver to Enzon
two (2) duly completed, appropriate and valid Withholding Certificates (as
defined under ss. 1.1441-1(c)(16) of the U.S. Income Tax Regulations)
certifying its status (i.e., U.S. or foreign person).

            Section 5.04. Affiliates. Each party guarantees that its Affiliates
shall comply with the terms and conditions of this Agreement relating thereto,
including, without limitation, the terms and conditions of this Agreement
applicable to the license of any rights hereunder.

            Section 5.05. Miscellaneous Terms. For the sake of brevity, this
Agreement incorporates by reference the provisions of the Asset Purchase
Agreement where this Agreement is silent. By way of example, such incorporation
includes but is not limited to Choice of Law, Indemnification, Confidentiality,
Public Announcements, Descriptive Headings, Injunctive Relief, Non-Waiver,
Relationship of the Parties, Severability, and Counterparts, as they appear in
the Asset Purchase Agreement.
