                                    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
in the Borough of Manhattan, The City of New York, 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, 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respect to any Bonds that are to be made from amounts withdrawn from the Payment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Indenture Trustee or by the Paying Agent, and no amounts so withdrawn from the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 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;



                                                         6

<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
related 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 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 business trust under the laws of the State
of Delaware (unless it becomes, or any


                                        7

<PAGE>



successor Issuer hereunder is or becomes, organized under the laws of any other
state or of the United States of America, in which case the Issuer will keep in
full effect its existence, rights and franchises under the laws of such other
jurisdiction) and will obtain and preserve its qualification to do business in
each jurisdiction in which such qualification is or shall be necessary to
protect the validity and enforceability of this Indenture, the Bonds, the
Mortgage Loans and each other instrument or agreement included in the Trust
Estate.

Insurer or used to pay principal to the Bondholders pursuant to clauses (b)(ii)

all other available funds.

         Section 3.12. REPRESENTATIONS AND WARRANTIES CONCERNING THE MORTGAGE

of the representations and warranties made by the Seller in the Mortgage Loan

and Contribution Agreement, the Indenture Trustee shall promptly notify 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.

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
the event of any such replacement the Issuer shall give written notice thereof
to the Rating Agencies.

                                   ARTICLE IV

               The Bonds; Satisfaction and Discharge of Indenture

         Section 4.01. THE BONDS. The Bonds shall be registered in the name of a
nominee desig nated 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 inte gral 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
aggregate Percentage Interests.


                                       20

<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 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 Bond holder 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


                                       21

<PAGE>



provided therefor to the extent of any loss, 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 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 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 Owner will receive a Definitive Bond representing such


                                       22

<PAGE>



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 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
Definitive Bonds to Beneficial Owners requesting the same. Upon surrender to the
Indenture Trustee of the


                                       23

<PAGE>



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, 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, 3.16, 3.18
and 3.19, (v) the rights, obligations and immunities of the Indenture Trustee
hereunder (including the rights of the Indenture Trustee under Section 6.07 and
the obligations of the Indenture Trustee under Section 4.11) and (vi) the rights
of 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



                                       24

<PAGE>



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

         and the Issuer, in the case of a. or b. above, has irrevocably
         deposited or caused to be irrevocably deposited with the Indenture
         Trustee cash or direct obligations of or obligations guaranteed by the
         United States of America (which will mature prior to the date such
         amounts are payable), in trust for such purpose, in an amount
         sufficient to pay and discharge the entire indebtedness on such 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 applicable, as the Indenture Trustee may determine, to the Holders of
Securities, of all sums due and to become due thereon for principal and interest
or otherwise; but such monies need not be segregated from other funds except to
the extent required herein or required by law.

         Section 4.12. SUBROGATION AND COOPERATION. (a) The Issuer and the
Indenture Trustee acknowledge that (i) to the extent the Bond Insurer makes
payments under either Bond Insurance Policy on account of principal of or
interest on the 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.



                                       25

<PAGE>



         The Indenture Trustee shall cooperate in all respects with any
reasonable request by the Bond Insurer for action 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 Bonds, or under this Indenture in respect
         to the 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 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 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 Bonds Outstanding for the
purposes of all approvals, consents, waivers and the institution of any action
and the direction of all remedies, and the Indenture Trustee shall act in
accordance with the 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,


                                       26

<PAGE>



photocopied or otherwise produced, in any denomination, substantially of the
tenor of the Definitive Bonds in lieu of which they are issued and 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 or agency of the Indenture
Trustee, 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 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.

                                    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) of the definition of "Event
of Default", its status and what action the Issuer is taking or proposes to take
with respect thereto.

         Section 5.02. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee at the written direction of the Bond Insurer (which such
written direction shall include a statement to the effect that such acceleration
is at the sole option of the Bond Insurer), or if a Bond Insurer Default exists
Holders of Bonds representing not less than a majority of the Bond Principal
Balances of all 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 given by
Bondholders), and upon any such declaration the unpaid Bond Principal Balance of
the Bonds, together with accrued and unpaid interest thereon through the date of
acceleration, shall become immediately due and payable.

         At any time after such declaration of acceleration of maturity with
respect to an Event of Default has been made and before a judgment or decree for
payment of the money due has been obtained by the Indenture Trustee as
hereinafter in this Article V provided, the Bond Insurer, unless a Bond Insurer
Default exists, or the Holders of Bonds representing a majority of the Bond
Principal Balances of all Bonds if a Bond Insurer Default exists, 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; and

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

                        (ii) all Events of Default, other than the nonpayment of
         the principal of the 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.


                                       28

         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,
pay to the Indenture Trustee, for the benefit of the Holders of Bonds and the
Bond Insurer, the whole amount then due and payable on the Bonds for principal
and interest, with interest at the 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 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


                                       29

<PAGE>



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 except as a result of negligence or bad faith 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 Bond
holder in any such proceeding except, as aforesaid, to vote for the election of
a trustee in bankruptcy or similar Person.

         (f) All rights of action and of asserting claims under this Indenture,
or under any of the Bonds, may be enforced by the Indenture Trustee without the
possession of any of the Bonds or


                                       30

<PAGE>



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, and
at the direction of the Bond Insurer so long as no Bond Insurer Default exists
shall, do one or more of the following (subject to Section 5.05 hereof):

                        (i) institute Proceedings in its own name and as trustee
         of an express trust for the collection of all amounts then payable on
         the 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, 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, (B) the proceeds of such sale
or liquidation distributable to the Holders of the Bonds are sufficient 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
related 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 become due if the
Bonds had not been declared due and payable, and the Indenture Trustee obtains
the consent of the Holders


                                       31

<PAGE>



of a majority of the aggregate Bond Principal Balance. In determining such
sufficiency or insufficiency with respect to clause (B) and (C), the Indenture
Trustee may, but need not, obtain and rely upon an opinion (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 Bondholders pursuant to
clauses THIRD and FOURTH below:

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

                  SECOND: 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;

                  THIRD: to the Bondholders for amounts due and unpaid on the
                  Bonds with respect to interest, ratably, without preference or
                  priority of any kind, according to the amounts due and payable
                  on the Bonds for interest (including any Unpaid Interest
                  Shortfalls);

                  FOURTH: to Bondholders for amounts due and unpaid on the Bonds
                  with respect to principal (including, but not limited to, any
                  related ARM Pool Principal Payment Amount or High LTV Pool
                  Principal Payment Amount), and to each Bondholder ratably,
                  without preference or priority of any kind, according to the
                  amounts due and payable on the Bonds for principal, until the
                  Bond Principal Balance is reduced to zero;

                  FIFTH: 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);

                  SIXTH: to the Bondholders for amounts due and unpaid on the
                  Bonds with respect to any Unpaid Interest Shortfalls or
                  Carry-Forward Amounts, ratably, without preference or priority
                  of any kind, according to the amounts due and payable on the
                  Bonds with respect thereto, from amounts available in the
                  Trust Estate for the Bondholders; and

                  SEVENTH: 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.



                                       32

<PAGE>



         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 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;

                        (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



                                       33

<PAGE>



                        (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 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


                                       34

<PAGE>



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 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, subject to the
         express terms of Section 5.04, 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
         Bonds;

                      (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
         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.

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 or might materially adversely affect the rights of
any Bondholders not consenting to such action.

         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 Bond Insurer, unless a Bond Insurer Default exists, or the Holders of Bonds
of not less than a majority of the Bond Principal Balances of the Bonds, if a
Bond Insurer Default exists, may waive any past Event of Default and its
consequences except an Event of Default (a) with respect to payment of principal
of or interest on any of the 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 related 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.



                                       35

<PAGE>



         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 by such Holder's acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Indenture Trustee for any action taken, suffered or omitted by it as
Indenture Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 5.13 shall not apply to (a) any suit instituted by
the Indenture Trustee, (b) any suit instituted by any 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.

         (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


                                       36

<PAGE>



                  (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 related 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 with the consent of the
Bond Insurer, so long as no Bond Insurer Default exists, 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
66-2/3% of the Bond Principal Balances of the 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 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 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 owing 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


                                       37

<PAGE>



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 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))


                                       38

<PAGE>



of the Bond Insurer or if a Bond Insurer Default exists, 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
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 on their face to the requirements
         of this Indenture to the extent specified herein.

         (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, which
         they are entitled to give under any of the Basic Documents or (B) from
         the Bond Insurer, which it is entitled to give under any of 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.

         (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


                                       40

<PAGE>



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 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 and shall not be liable for the
action or inaction of any such person appointed by it with due
care.

         (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.

         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. 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 or any other Person 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.



                                       41

<PAGE>



         Section 6.05. NOTICE OF EVENT OF DEFAULT. If an Event of Default occurs
and is continuing and if it is actually known to a Responsible Officer of the
Indenture Trustee, the Indenture Trustee shall give prompt notice thereof to the
Bond Insurer. The Trustee shall mail to each Bondholder notice of the Event of
Default within 10 days after a Responsible Officer of the Indenture Trustee
obtains actual knowledge thereof, 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. In addition, upon the Issuer's written request, the
Indenture Trustee shall promptly furnish information reasonably requested by the
Issuer that is reasonably available to the Indenture Trustee to enable the
Issuer to perform its federal and state income tax reporting obligations.

         The Indenture Trustee shall prepare and file (or cause to be prepared
and filed), on behalf of the Owner Trustee, all 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.

         For purposes of preparing Form 1099 and any other information report
requiring the provision of a federal employer identification number (EIN), so
long as the Trust is disregarded for federal income tax purposes the Indenture
Trustee shall use the EIN of IMPAC Mortgage Holdings, Inc. In the event the
Trust is to be treated as a partnership or the certificates are in any event
transferred to another person, the Master Servicer shall provide the Indenture
Trustee with the applicable EIN.

         Section 6.07. COMPENSATION AND INDEMNITY. The Issuer shall pay to the
Indenture Trustee on each Payment Date reasonable compensation for its services.
The amount of the Indenture Trustee Fee shall be paid by the Master Servicer to
the Indenture Trustee on each Payment Date pursuant to Section 3.07(a)(x) of the
Servicing Agreement and all amounts owing to the Indenture Trustee hereunder
(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(b)(viii),
Section 3.05(c)(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
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 and any director, officer, employee or agent of
the Indenture Trustee or any Person that "controls" the Trustee within the
meaning of the Securities Act and the Exchange Act 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


                                       42

<PAGE>



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
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.



                                       43

<PAGE>



         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.

         No termination of the Indenture Trustee without cause will be effective
unless the costs and expenses of such Indenture Trustee have been reimbursed in
connection with such removal.

         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 meet ing any legal requirement of any jurisdiction in
which any part of the Trust Estate may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
appoint one or more Persons to act as a co-trustee or co-trustees, or separate
trustee or separate trustees, of all or any part of the Trust Estate, and to
vest in such Person or Persons, in such capacity and for the benefit of the
Bondholders and the Bond Insurer, such title to the Trust Estate, or any part
hereof, and, subject to the other provisions of this Section, such powers,
duties, obli gations, rights and trusts as the Indenture Trustee or the Bond
Insurer may consider necessary or desirable. No co-trustee or separate trustee
hereunder shall be required to meet the terms of eligibility as a successor
trustee under Section 6.11 hereof and notice to the Bond Insurer but not to the
Bondholders of the appointment of any co-trustee or separate trustee shall be
required under Section 6.08 hereof.



                                       44

<PAGE>



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

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

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

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

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

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

         Section 6.11. ELIGIBILITY; DISQUALIFICATION. The Indenture Trustee

Trustee shall apply all such money received by it as provided in this Indenture.
Except as otherwise expressly provided in this Indenture, if any default occurs

         Section 8.04. TERMINATION UPON DISTRIBUTION TO BONDHOLDERS. This

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

or see to the application of any monies.

         (b) The Indenture Trustee shall, at such time as (i) there are no Bonds
Outstanding, (ii) all sums due to the Indenture Trustee pursuant to this
Indenture have been paid and (iii) all sums due to the Bond Insurer have been

Indenture pursuant to this Section 8.05 only upon receipt of a request from the
Issuer accompanied by an Officers' Certificate and an Opinion of Counsel stating
that all applicable requirements have been satisfied, and a letter from the Bond
Insurer stating that the Bond Insurer has no objection to such request from the
Issuer.

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

         Section 8.07. OPTIONAL REDEMPTION OF THE BONDS. (a) The Issuer shall
have the option to redeem the Bonds in whole, but not in part, on any Payment
Date on or after the earlier of (i) the Payment Date on which the aggregate
Principal Balance of the Mortgage Loans is less than or equal to 25% of the
aggregate Principal Balance of the Mortgage Loans as of the Cut-off Date or (ii)
the Payment Date occurring in March 2006. The aggregate redemption price for the
Bonds, as evidenced by an Officer's Certificate of the Master Servicer addressed
to the Indenture Trustee attesting to the accuracy and detailing the steps of
such calculation, will be equal to the unpaid Bond Principal Balance of the
Bonds as of the Payment Date on which the proposed redemption will take place in
accordance with the foregoing, together with accrued and unpaid interest thereon
at the Bond Interest Rate through such Payment Date (including any Unpaid
Interest Shortfalls and Carry-Forward Amounts), plus an amount sufficient to pay
in full all amounts owing to the Bond Insurer and the Indenture Trustee under
this Indenture and the Insurance Agreement (which


                                       53

<PAGE>



amounts shall be specified in writing upon request of the Issuer by the
Indenture Trustee and the Bond Insurer).

         (b) In order to exercise the foregoing option, the Issuer shall, not
less than 15 days prior to the proposed Payment Date on which such redemption is
to be made, deposit the aggregate redemption price specified in (a) above with
the Indenture Trustee, and shall provide written notice of its exercise of such
option to the Indenture Trustee, the Bond Insurer, the Owner Trustee and the
Master Servicer. Following receipt of the notice and the aggregate redemption
price, calculated as specified in Section 8.07(a) hereof, pursuant to the
foregoing, the Indenture Trustee shall provide notice to the Bondholders of the
final payment on the Bonds and shall apply such funds to make final payments of
principal and interest on the Bonds in accordance with Section 3.05(b) and
3.05(c) hereof, and this Indenture shall be discharged subject to the provisions
of Section 4.10 hereof. If for any reason the amount deposited by the Issuer is
not sufficient to make such redemption or such redemption cannot be completed
for any reason, the amount so deposited by the Issuer with the Indenture Trustee
shall be immediately returned to the Issuer in full and shall not be used for
any other purpose or be deemed to be part of the Trust Estate.

         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;


                                       55

<PAGE>



provided, however, that no such indenture supplements shall be entered into
unless the Indenture Trustee shall have received an Opinion of Counsel 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 Balances of the 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


                                       56

<PAGE>



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

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

                        (iv) reduce the percentage of the 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.

         The Indenture Trustee may, with the consent of the Bond Insurer, so
long as no Bond Insurer Default exists, in its discretion determine whether or
not any Bonds would be affected by any supplemental indenture and any such
determination shall be conclusive upon the Holders of all Bonds, whether
theretofore or thereafter authenticated and delivered hereunder. The Indenture
Trustee shall not be liable for any such determination made in good faith.

         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 require ments of the Trust Indenture Act as then
in effect so long as this Indenture shall then be qualified under the Trust
Indenture Act.

         Section 9.06. REFERENCE IN 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 Inden ture
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.



                                       59

<PAGE>



                            (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
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


                                       60

<PAGE>



such factual matters is in the possession of the Seller or the Issuer, unless
such counsel knows, or in the exercise of reasonable care should know, that the
certificate or opinion or representations with respect to such matters are
erroneous.

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

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

         Section 10.03. ACTS OF 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


                                       61

<PAGE>



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:

                            (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 1999-1, in care of Wilmington Trust Company,
         Rodney Square North, 1100 North Market Street, Wilmington, Delaware
         19890-0001, Attention: Corporate Trust Administration, or at any other
         address previously furnished in writing to the Indenture Trustee by the
         Issuer. The Issuer shall promptly transmit any notice received by it
         from the 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: Structured
         Finance-Mortgage Backed Securities, Telephone (212) 208-3387,
         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, 26 Broadway (15th Floor),
New York, New York 10004, 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.


                                       62

<PAGE>



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

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

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

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

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

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

         Section 10.08. SUCCESSORS AND ASSIGNS. All covenants and agreements in
this Indenture and the Bonds by the Issuer shall bind its successors and
assigns, whether so expressed or not. All agreements of the Indenture Trustee in
this Indenture shall bind its successors, 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.



                                       63

         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
effect as if made on the date on which nominally due, and no interest shall
accrue for the period from and after any such nominal date.

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

         Impac CMB Trust Series 1999-1 (the "Issuer"), a Delaware business
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 March 1999 and ending on or before the
Payment Date occurring in _____________________________ (the "Stated Maturity")
and to pay interest on the Bond Principal Balance of this Class A-1 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 1999-1 (the "Bonds"), issued under an
Indenture dated as of February 26, 1999 (the "Indenture"), between the Issuer
and LaSalle National Bank, 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 Insured Amount with respect to the
Class A-1 Bonds with respect to each Payment Date. Such Bond Insurance Policy
will not cover any Prepayment Interest Shortfalls, Relief Act Shortfalls or ARM
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. On each
Payment Date, Bondholders will be entitled to receive interest payments in an
aggregate amount equal to the aggregate Accrued Bond Interest for such Payment
Date, together with principal payments in an aggregate amount equal to the ARM
Pool Principal Payment Amount, if any, for such Payment 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 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.




<PAGE>



         The Bonds are subject to redemption in whole, but not in part, by the
Issuer on any Payment Date on or after the earlier of (i) the Payment Date on
which the aggregate Principal Balance of the Mortgage Loans is less than or
equal to 25% of the aggregate Principal Balance of the Mortgage Loans as of the
Cut-off Date and (ii) the Payment Date in March 2006.

         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 and payments under the Bond Insurance Policy will be the sole
source of payments on the 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 and the Bond Insurance Policy 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. (formerly known as Imperial Credit Mortgage Holdings,
Inc.), the Master Servicer or any of their respective affiliates, or to the
assets of any of the foregoing entities, except the assets of the Issuer pledged
to secure the Bonds pursuant to the Indenture and the rights conveyed to the
Issuer under the Indenture and the Bond Insurance Policy.

         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 described in the Indenture.
The



<PAGE>



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.

         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 Bonds for certain purposes specified in the Indenture (other than with
respect to payment on the 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 discretion, including actions
relating to the occurrence of, and the remedies with respect to, an Event of
Default, only at the direction 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 a Bond Insurer Default
exists, 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.



<PAGE>



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.

aggregate amount equal to the aggregate Accrued Bond Interest for such Payment
Date, together with principal payments in an aggregate amount equal to the High
LTV Pool Principal Payment Amount, if any, for such Payment 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 Bonds as
described above, and shall be applied as between interest and principal as
provided 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 Insured Amount for the Class A-2 Bonds
with respect to each Payment Date. Such Bond Insurance Policy will not cover any
Prepayment Interest Shortfalls, Relief Act Shortfalls or High LTV Pool Basis
Risk Shortfall Carry-Forward Amount.

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




<PAGE>



         The Bonds are subject to redemption in whole, but not in part, by the
Issuer on any Payment Date on or after the earlier of (i) the Payment Date on
which the aggregate Principal Balance of the Mortgage Loans is less than or
equal to 25% of the aggregate Principal Balance of the Mortgage Loans as of the
Cut-off Date and (ii) the Payment Date in March 2006.

         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 and payments under the related Bond Insurance Policy will be the
sole source of payments on the 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 and the related Bond Insurance Policy 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. (formerly known as Imperial Credit Mortgage Holdings,
Inc.), the Master Servicer or any of their respective affiliates, or to the
assets of any of the foregoing entities, except the assets of the Issuer pledged
to secure the Bonds pursuant to the Indenture and the rights conveyed to the
Issuer under the Indenture and the related Bond Insurance Policy.

         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



<PAGE>



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.

         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 Bonds for certain purposes specified in the Indenture (other than with
respect to payment on the 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 discretion, including actions
relating to the occurrence of, and the remedies with respect to, an Event of
Default, only at the direction 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 a Bond Insurer Default
exists, 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



<PAGE>



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.

         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.

                          W I T N E S S E T H  T H A T :
                          - - - - - - - - - -  - - - -


                  WHEREAS, pursuant to the terms of a Mortgage Loan Sale and
Contribution Agreement, dated as of the Closing Date (the "MLSCA"), Impac

                  NOW, THEREFORE, in consideration of the premises and the

the Master Servicer and the Custodian hereby agree as follows:

                                       -2-


                                    ARTICLE I

                                   Definitions

                  Section 1.1. DEFINITIONS. Capitalized terms used and not
defined herein shall have the meanings assigned thereto in the Definitions
contained in Appendix A to the Indenture dated February 26, 1999 (the
"Indenture"), between Impac CMB Trust Series 1999-1, as issuer, and LaSalle
National Bank, as indenture trustee, which is incorporated by reference herein.


                                   ARTICLE II

                        Custody of the Mortgage Documents

                  Section 2.1. CUSTODIAN TO ACT AS AGENT; ACCEPTANCE OF THE
MORTGAGE FILES. The Custodian, as the duly appointed agent of the Indenture
Trustee for these purposes, acknowledges receipt of the mortgage files (the
"Mortgage Files") purporting to contain the Related Documents relating to each
of the Mortgage Loans identified on Schedule A attached hereto (the "Mortgage
Loan Schedule") and declares that it holds and will hold the Mortgage Files as
agent solely for the Indenture Trustee in trust, for the use and benefit of the
Securities and the Bond Insurer.

                  Pursuant to Section 8.05 of the Indenture, the Indenture
Trustee, as pledgee of the Mortgage Loans, may execute instruments to release
property from the Issuer, in a manner consistent with the provisions of the
Indenture. In connection with the foregoing, the Indenture Trustee, as pledgee
of the Mortgage Loans, shall provide promptly a copy of such executed
instruments to the Custodian. No party relying upon an instrument executed by
the Indenture Trustee, as pledgee of the Mortgage Loans, as provided in this
Section 2.1 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 moneys.

                  Section 2.2. RECORDATION OF ASSIGNMENTS. If and to the extent
requested to do so by the Seller, the Custodian shall complete the assignment of
Mortgage in blank included in each Mortgage File in the name of the Indenture
Trustee, as pledgee of the Mortgage Loans, and shall deliver each such
assignment to the Seller for the purpose of recording it in the appropriate
public office for real property records. The Seller, at no expense to the
Custodian, shall, pursuant to Section 2.1(c) of the MLSCA, promptly cause to be
recorded in the appropriate public office for real property records of each such
assignment completed in favor of the Indenture Trustee, as pledgee of the
Mortgage Loans, and, upon receipt thereof from such public office, shall return
each such assignment to the Custodian.

                  Section 2.3.  REVIEW OF THE MORTGAGE FILES.

                  (a) The Custodian 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)(i) through (v) of
the MLSCA and declares that it holds and will continue to hold



<PAGE>


                                       -3-


those documents and any amendments, replacements or supplements thereto on
behalf of the 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 Business Days after the receipt by the Custodian thereof and,
with respect to any documents received beyond 45 days after the Closing Date,
promptly thereafter), the Custodian 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 Indenture
Trustee, as pledgee of the Mortgage Loans, an Initial Certification in the form
annexed hereto as Exhibit 1. In conducting such review, the Custodian will
ascertain whether all required documents described in Section 2.1(b) of the
MLSCA 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 Schedule A,
as supplemented (PROVIDED, HOWEVER, that with respect to those documents
described in subclause (b)(vii) of such section, the Custodian's obligations
shall extend only to documents actually delivered pursuant to such subclause).
In performing any such review, the Custodian may conclusively rely on the
purported due execution and genuineness of any such document and on the
purported genuineness of any signature thereon. If the Custodian 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 Schedule A or
to appear to be defective on its face, the Custodian shall promptly notify the
Indenture Trustee, 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.

         (b) No later than 180 days after the Closing Date, the Custodian will
review on behalf of the Indenture Trustee as pledgee of the Mortgage Loans, 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 Indenture
Trustee, as pledgee of the Mortgage Loans, a Final Certification in the form
annexed hereto as Exhibit 2. In conducting such review, the Custodian will
ascertain whether an original of each document described in subclauses
(b)(ii)-(iv) of Section 2.1 of the MLSCA required to be recorded has been
returned from the recording office with evidence of recording thereon or a
certified copy has been obtained from the recording office. If the Custodian
finds any document constituting part of the Mortgage File has not been received,
or to be unrelated, determined on the basis of the Mortgagor name, original
principal balance and loan number, to the Mortgage Loans identified in Schedule
A or to appear defective on its face, the Custodian shall promptly notify the
Indenture Trustee, the Seller and the Bond Insurer.

                  Upon receipt of written request from the Indenture Trustee, as
pledgee of the Mortgage Loans, the Custodian shall as soon as practicable supply
the Indenture Trustee, as pledgee of the Mortgage Loans, with a list of all of
the documents relating to the Mortgage Loans then contained in the Mortgage
Files and reviewed as required pursuant to Section 2.3 hereof.

                  Custodian makes no representations as to (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, or (ii) the collectability, insurability, effectiveness or
suitability of any such Mortgage Loan, and Custodian shall incur no liability or
responsibility in respect of any such matters.

                                       -4-


                  Section 2.4. NOTIFICATION OF BREACHES OF REPRESENTATIONS AND
WARRANTIES. Upon discovery by the Custodian of a breach of any representation or
warranty made by (i) the Seller in the MLSCA or assigned by the Seller pursuant
to the MLSCA or (ii) the Master Servicer in the Servicing Agreement or assigned
by the Master Servicer pursuant to the Servicing Agreement, with respect to a
Mortgage Loan relating to a Mortgage File, the Custodian shall give prompt
written notice to the Seller or the Master Servicer, as applicable, and the Bond
Insurer.

                  Section 2.5. CUSTODIAN TO COOPERATE; RELEASE OF THE MORTGAGE
FILES. The Master Servicer shall notify the Custodian (with a copy to the
Indenture Trustee) of the termination of or the payment in full and the
termination of any Mortgage Loan, by a certification of a Request for Release in
one of the forms of Exhibit 3 (or an electronic request in a form acceptable to
the Custodian) of this Agreement, signed by a Servicing Officer (which
certification shall include a statement to the effect that all amounts received
or to be received in connection with such payments which are required to be
deposited pursuant to the Servicing Agreement have been or will be so deposited)
and shall request delivery to it of the Mortgage File. The Custodian agrees,
upon receipt of such certification and request, promptly to release to the
Master Servicer the related Mortgage File. The Master Servicer shall deliver to
the Custodian and the Custodian agrees to accept the Mortgage Note and other
documents constituting the Mortgage File with respect to any Eligible Substitute
Loan.

                  From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan, the Custodian shall, upon request of the
Master Servicer and delivery to the Custodian, with a copy to the Indenture
Trustee, as pledgee of the Mortgage Loans, of a trust receipt in one of the
forms annexed hereto as Exhibit 3, signed by a Servicing Officer, release or
cause to be released the related Mortgage File to the Master Servicer. Such
trust receipt shall obligate the Master Servicer to return the Mortgage File to
the Custodian (specified in such receipt) when the need therefor by the Master
Servicer no longer exists unless the Mortgage Loan shall be liquidated, in which
case, upon receipt of a Request for Release of a Servicing Officer in one of the
forms of Exhibit 3, the trust receipt shall be released to the Master Servicer.

                  Section 2.6. ASSUMPTION AGREEMENTS. In the event that any
assumption agreement or substitution of liability agreement is entered into with
respect to any Mortgage Loan subject to this Agreement in accordance with the
terms and provisions of the Servicing Agreement, the Master Servicer shall
notify the Custodian, the Indenture Trustee and the Bond Insurer that such
assumption or substitution agreement has been completed and shall forward to the
Custodian, with a copy to the Bond Insurer, the original of such assumption or
substitution agreement, which shall be added to the related Mortgage File and,
for all purposes, shall be considered a part of such Mortgage File to the same
extent as all other documents and instruments constituting parts thereof.


                                   ARTICLE III

                            Concerning the Custodian




<PAGE>


                                       -5-


                  Section 3.1. CUSTODIAN AS BAILEE AND AGENT OF THE INDENTURE
TRUSTEE. With respect to each Mortgage Note, Mortgage and other Related
Documents constituting each Mortgage File which are delivered to the Custodian,
the Custodian is exclusively the bailee of the Indenture Trustee and has no
instructions to hold any Mortgage Note or Mortgage for the benefit of any person
other than the Indenture Trustee and undertakes to perform such duties and only
such duties as are specifically set forth in this Agreement. Except upon
compliance with the provisions of Section 2.2, Section 2.3(b) or Section 2.5 of
this Agreement, no Mortgage Note, Mortgage or other document constituting a part
of a Mortgage File shall be delivered by the Custodian to the Master Servicer or
otherwise released from the possession of the Custodian.

                  Section 3.2. INDEMNIFICATION. The Master Servicer hereby
agrees to indemnify and hold the Custodian harmless from and against all claims,
liabilities, losses, actions, suits or proceedings at law or in equity, or any
other expenses, fees or charges of any character or nature, which the Custodian
may incur or with which the Custodian may be threatened by reason of its acting
as custodian under this Agreement, including indemnification of the Custodian
against any and all expenses, including reasonable attorney's fees, and the cost
of defending any action, suit or proceedings or resisting any claim.
Notwithstanding the foregoing, it is specifically understood and agreed that in
the event any such claim, liability, loss, action, suit or proceeding or other
expense, fee or charge shall have been caused by reason of any negligent act,
negligent failure to act, willful misconduct or bad faith on the part of the
Custodian, or which shall constitute a willful breach of its duties hereunder,
the indemnification provisions of this Agreement shall not apply.

                  Section 3.3. CUSTODIAN MAY OWN SECURITIES. The Custodian in
its individual or any other capacity may become the owner or pledgee of the
Securities with the same rights it would have if it were not Custodian.

                  Section 3.4. MASTER SERVICER TO PAY CUSTODIAN'S FEES AND
EXPENSES. The Master Servicer covenants and agrees on behalf of the Issuer to
pay to the Custodian from time to time, and the Custodian shall be entitled to,
reasonable compensation for all services rendered by it in the exercise and
performance of any of the powers and duties hereunder of the Custodian, and the
Master Servicer will pay or reimburse the Custodian upon its request for all
reasonable expenses, disbursements and advances incurred or made by the
Custodian in accordance with any of the provisions of this Agreement (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all persons not regularly in its employ), except any such expense,
disbursement or advance as may arise from its negligence, willful misconduct or
bad faith.

                  Section 3.5. CUSTODIAN MAY RESIGN; INDENTURE TRUSTEE MAY
REMOVE CUSTODIAN. The Custodian may resign from the obligations and duties
hereby imposed upon it as such obligations and duties relate to its acting as
the Custodian of the Mortgage Loans. Upon receiving such notice of resignation,
the Indenture Trustee, as pledgee of the Mortgage Loans and with the consent of
the Bond Insurer, shall either take custody of the Mortgage Files itself and
give prompt notice thereof to the Master Servicer, the Bond Insurer and the
Custodian, or promptly appoint a successor Custodian by written instrument, in
triplicate, one copy of which instrument shall be delivered to the resigning
Custodian, one copy to the successor Custodian and one copy to the Bond Insurer.
If the Indenture Trustee, as pledgee of the Mortgage Loans shall not have taken
custody of the Mortgage

Files and no successor Custodian shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Custodian may petition any court of competent jurisdiction for the
appointment of a successor Custodian.

                  The Indenture Trustee, as pledgee of the Mortgage Loans may
remove the Custodian at any time for cause, based upon a material breach by the
Custodian of its duties and obligations hereunder. In such event, the Indenture
Trustee, as pledgee of the Mortgage Loans shall appoint, or petition a court of
competent jurisdiction to appoint, a successor Custodian hereunder. Any
successor Custodian shall be a depository institution subject to supervision or
examination by federal or state authority and shall be able to satisfy the other
requirements contained in Section 3.7 and shall be unaffiliated with the
Depositor or the Issuer.

                  Any resignation or removal of the Custodian and appointment of
a successor Custodian pursuant to any of the provisions of this Section 3.5
shall become effective upon acceptance of appointment by the successor
Custodian. The Indenture Trustee, as pledgee of the Mortgage Loans shall give
prompt notice to the Depositor and the Master Servicer of the appointment of any
successor Custodian. No successor Custodian other than LaSalle National Bank
shall be appointed by the Indenture Trustee, as pledgee of the Mortgage Loans
without the prior approval of the Depositor, the Bond Insurer and the Master
Servicer.

                  Section 3.6. MERGER OR CONSOLIDATION OF CUSTODIAN. Any Person
into which the Custodian may be merged or converted or with which it may be
consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Custodian shall be a party, or any Person succeeding
to the business of the Custodian, shall be the successor of the Custodian
hereunder, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                  Section 3.7. REPRESENTATIONS OF THE CUSTODIAN. The Custodian
hereby represents that it is a depository institution subject to supervision or
examination by a federal or state authority, has a combined capital and surplus
of at least $10,000,000 and is qualified to do business in the
jurisdictions in which it will hold any Mortgage File.

                  Section 3.8. INDEMNIFICATION OF THE INDENTURE TRUSTEE. The
Indenture Trustee and any director, officer, employee or agent of the Indenture
Trustee or any Person that "controls" the Indenture Trustee within the meaning
of the 1933 Act and the 1934 Act shall be entitled to indemnification by the
Custodian for any loss, liability or expense (including without limitation costs
and expenses of litigation, and of investigation, counsel fees, damages,
judgments and amounts paid in settlement) incurred by the Indenture Trustee or
such other person and arising out of the transactions contemplated by this
Agreement including, without limitation, those incurred in connection with the
Indenture Trustee or Custodian (i) performing their respective duties under this
Agreement and the Indenture Trustee enforcing its rights and remedies and
protecting the interests, and enforcing the rights and remedies of the
Bondholders and (ii) the defending or prosecuting any legal action in respect of
this Agreement or the Bonds; provided, however, that such indemnification will

or negligence on the part of the Indenture Trustee in the performance of its
obligations and duties thereunder; provided, however, that with respect to any
third party claim:

                  (1)      the Indenture Trustee shall have given the Custodian
                           written notice thereof promptly after a Responsible
                           Officer of the Indenture Trustee shall have actual
                           knowledge thereof except that any failure to give
                           such notice shall not in any way limit the right to
                           indemnification set forth in this Section 3.8;

                  (2)      while maintaining control over its own defense, the
                           Indenture Trustee shall cooperate and consult fully
                           with the Custodian in preparing such defense; and

                  (3)      notwithstanding anything to the contrary in this
                           Section 3.8, the Custodian shall not be liable for
                           settlement of any such claim by the Indenture
                           Trustee, entered into without the prior consent of
                           the Custodian, which consent shall not be
                           unreasonably withheld.

The foregoing indemnification shall survive any termination or assignment of
this Agreement.

                                   ARTICLE IV

                  Section 4.4. RECORDATION OF AGREEMENT. To the extent permitted
by applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the
Mortgages are situated, and in any other appropriate public recording office or
elsewhere, such recordation to be effected by the Master Servicer and at its
expense on direction by the Indenture Trustee, as pledgee of the Mortgage Loans,
but only upon direction accompanied by an Opinion of Counsel obtained at the
expense of the Master Servicer and reasonably satisfactory to the Master
Servicer to the effect that the failure to effect such recordation is likely to
materially and adversely affect the interests of the Securities or the Bond
Insurer.

                  For the purpose of facilitating the recordation of this
Agreement as herein provided and for other purposes, this Agreement may be
executed simultaneously in any number of counterparts, each of which
counterparts shall be deemed to be an original, and such counterparts
shall constitute but one and the same instrument.

                  Section 4.5. SEVERABILITY OF PROVISIONS. If any one or more of
the covenants, agreements, provisions or terms of this Agreement shall be for
any reason whatsoever held invalid, then such covenants, agreements, provisions
or terms shall be deemed severable from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Securities or
the rights of the Holders thereof.

                  Section 4.6. RELIANCE OF CUSTODIAN. In the absence of bad
faith on the part of the Custodian, the Custodian may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon any request, instructions, certificate, opinion or other document
furnished to the Custodian, reasonably believed by the Custodian to be genuine
and to have been signed or presented by the proper party or parties and
conforming to the requirements of this Agreement; but in the case of any loan
document or other request, instruction, document or certificate which by any
provision hereof is specifically required to be furnished to the Custodian, the
Custodian shall be under a duty to examine the same to determine whether or not
it conforms to the requirements of this Agreement

                  Section 4.7. TRANSMISSION OF MORTGAGE FILES AND OTHER
DOCUMENTS. Prior to any shipment of any Mortgage Files hereunder, the requesting
party shall deliver to the Custodian written instructions as to the method of
shipment and shipper(s) the Custodian is to utilize in connection with the
transmission of Mortgage Files or other loan documents in the performance of the
Custodian's duties hereunder. The requesting party shall arrange for the
provision of such services at its sole cost and expense (or, at the Custodian's
option, reimburse the Custodian for all costs and expenses incurred by the
Custodian consistent with such instructions) and will maintain such insurance
against loss or damage to mortgage files or other loan documents as the
requesting party deems appropriate. Without limiting the generality of the
provisions of Section 3.2 above, it is expressly agreed that in no event shall
the Custodian have any liability for any losses or damages to any person,
including without limitation, the Indenture Trustee or the Master Servicer,
arising out of actions of the Custodian consistent with instruction of the
requesting party. In the event the
