      No Bond shall be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose, unless there appears on such Bond a certificate

Indenture Trustee by the manual signature of one of its authorized signatories,
and such certificate upon any Bond shall be conclusive evidence, and the only
evidence, that such Bond has been duly authenticated and delivered hereunder.

      Section 2.03 Acceptance of Mortgage Loans by Indenture Trustee. (a) The
Custodian as agent for the Indenture Trustee acknowledges receipt of, subject to
the exceptions it notes pursuant to the procedures described below, the
documents (or certified copies thereof) referred to in Section 2.1(b) of the
Mortgage Loan Purchase Agreement, and declares that it holds and will continue
to hold those documents and any amendments, replacements or supplements thereto
and all other assets of the Trust Estate as agent for the Indenture Trustee in
trust for the use and benefit of all present and future Holders of the Bonds. No
later than 45 days after the Closing Date, with respect to the Initial Mortgage
Loans, or the applicable Subsequent Transfer Date, with respect to the related
Group 1 Subsequent Mortgage Loans and Group 2 Subsequent Mortgage Loans (or,
with respect to any Eligible Substitute Mortgage Loan, within 5 days after the
receipt by the Custodian as agent for the Indenture Trustee thereof and, with
respect to any documents received beyond 45 days after the Closing Date,
promptly thereafter), the Custodian as agent for the Indenture Trustee agrees,
for the benefit of the Bondholders, to review each Mortgage File delivered to it
and to execute and deliver, or cause to be executed and delivered, to the
Seller, the Indenture Trustee and the Master Servicer an Initial Certification
in the form annexed to the Custodial Agreement as Exhibit One. In conducting
such review, the Custodian as agent for the Indenture Trustee will ascertain
whether all required documents described in Section 2.1(b) of (i) the Mortgage
Loan Purchase Agreement, with respect to the Initial Mortgage Loans, and (ii)
the applicable Group 1 Subsequent Mortgage Loan Purchase Agreements and Group 2
Subsequent Mortgage Loan Purchase Agreements, with respect to the related Group
1 Subsequent Mortgage Loans and Group 2 Subsequent Mortgage Loans, respectively,
have been executed and received and whether those documents relate, determined
on the basis of the Mortgagor name, original principal balance and loan number,
to the Mortgage Loans it has received, as identified in Exhibit B to this
Indenture, as supplemented (provided, however, that with respect to those
documents described in subclause (b)(vii) of such section, the 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 as agent for
the Indenture Trustee finds any document constituting part of the Mortgage File
not to have been executed or received, or to be unrelated to the Mortgage Loans
identified in Exhibit B to this Indenture or to appear to be defective on its
face, the Custodian as agent for the Indenture Trustee shall promptly notify the
Seller of such finding and the Seller's obligation to cure such defect or
repurchase or substitute for the related Mortgage Loan. To the extent the
Custodian as agent for the Indenture Trustee has not received a Mortgage File
with respect to any of the Initial Mortgage Loans by the Closing Date, or any of
the related Group 1 Subsequent Mortgage Loans and Group 2 Subsequent Mortgage
Loans by the applicable Subsequent Transfer Date, neither the Indenture Trustee
nor the Custodian as agent for the Indenture Trustee shall require
the deposit of cash into the Payment Account or any other account to cover the
amount

                                       6

of that Mortgage Loan and shall solely treat such Mortgage Loan as if it were in
breach of a representation or warranty; provided that the aggregate Stated
Principal Balance of such Mortgage Loans does not exceed 1% of the sum of the
Cut-off Date Balance and the Group 1 Original Pre-Funded Amount and Group 2
Original Pre-Funded Amount.

      (b) No later than 180 days after the Closing Date (with respect to the
Initial Mortgage Loans) or the applicable Subsequent Transfer Date (with respect
to the related Group 1 Subsequent Mortgage Loans and Group 2 Subsequent Mortgage
Loans), the Custodian as agent for the Indenture Trustee will review, for the
benefit of the Bondholders, the Mortgage Files and will execute and deliver or
cause to be executed and delivered to the Seller and the Indenture Trustee, a
Final Certification in the form annexed to the Custodial Agreement as Exhibit
Two. In conducting such review, the Custodian as agent for the Indenture Trustee
will ascertain whether an original of each document described in subclauses
(b)(ii)-(iv) of Section 2.1 of (i) the Mortgage Loan Purchase Agreement, with
respect to the Initial Mortgage Loans, and (ii) any Group 1 or Group 2
Subsequent Mortgage Loan Purchase Agreement, with respect to the related Group 1
Subsequent Mortgage Loans and Group 2 Subsequent Mortgage Loans, 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 as agent for the Indenture Trustee finds any document constituting
part of the Mortgage File has not been received, or to be unrelated, determined
on the basis of the Mortgagor name, original principal balance and loan number,
to the Mortgage Loans identified in Exhibit B to this Indenture or to appear
defective on its face, the Custodian as agent for the Indenture Trustee shall
promptly notify the Seller and the Indenture Trustee.

      (c) Upon deposit of the Repurchase Price in the Payment Account, the
Custodian as agent for the Custodian as agent for the Indenture Trustee shall
release to the Seller the related Mortgage File and shall execute and deliver
all instruments of transfer or assignment, without recourse, furnished to it by
the Seller as are necessary to vest in the Seller title to and rights under the
related Mortgage Loan. Such purchase shall be deemed to have occurred on the
date on which the deposit of the Repurchase Price in the Payment Account was
received by the Indenture Trustee. The Custodian as agent for the Indenture
Trustee shall amend the applicable Mortgage Loan Schedule to reflect such
repurchase and shall promptly notify the Master Servicer, the Rating Agencies
and the Indenture Trustee of such amendment.

      Section 2.04 Acceptance of Derivative Contracts and Special Certificate
Cap Contract by Indenture Trustee. The Indenture Trustee acknowledges receipt of
the Derivative Contracts and the Special Certificate Cap Contract and declares
that it holds and will continue to hold these documents and any amendments,
replacements or supplements thereto and all other assets of the Trust Estate as
Indenture Trustee in trust for the use and benefit of all present and future
Holders of the Bonds. The Indenture Trustee shall enforce the Derivative
Contracts and the Special Certificate Cap Contract in accordance with their
terms.

                  (iii) at any time during the continuance of any such default,

                  (iv) immediately resign as Paying Agent and forthwith pay to
      the Indenture Trustee all sums held by it in trust for the payment of

                  (v) comply with all requirements of the Code with respect to

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

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

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

have possession of such Related Documents, such monies and such other items for

(taking into account not only the general definition of the term "investment
company" but also any available exceptions to such general definition);

if it shall have obtained an order exempting it from regulation as an
"investment company" so long as it is in compliance with the conditions imposed
in such order.

as applicable, within the meaning of the applicable UCC.

            (iii) The Issuer owns and has good and marketable title to the
Collateral, free and clear of any lien, claim or encumbrance of any Person.

            (iv) The Issuer has taken all steps necessary to cause the Indenture
Trustee to become the account holder of the Collateral.

            (v) Other than the security interest granted to the Indenture

granted a security interest in, or otherwise conveyed any of the Collateral.

Class M-3-2, Class M-3- 1, Class M-2-2, Class M-2-1, Class M-1-2 and Class
M-1-1, in that order, shall be reduced, until the Bond Principal Balance thereof
has been reduced to zero. All Realized Losses allocated to a Class of Bonds will
be allocated in proportion to the Percentage Interests evidenced thereby.

                                   ARTICLE IV

               The Bonds; Satisfaction and Discharge of Indenture

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

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

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

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

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

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

                                       35
<PAGE>

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

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

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

      Section 4.03 Mutilated, Destroyed, Lost or Stolen Bonds. If (i) any
mutilated Bond is surrendered to the Indenture Trustee, or the Indenture Trustee
receives evidence to its satisfaction of the destruction, loss or theft of any
Bond, and (ii) there is delivered to the Indenture Trustee such security or
indemnity as may be required by it to hold the Issuer 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 and the Indenture Trustee shall be entitled to recover
such replacement Bond (or such payment) from the Person to whom it was delivered
or any Person taking such replacement Bond from such Person to whom such
replacement Bond was delivered or any assignee of such Person, except a bona
fide purchaser, and shall be entitled to recover upon the security or indemnity
provided therefor to the extent of any loss, damage, cost or expense incurred by
the Issuer or the Indenture Trustee in connection therewith.

                                       36
<PAGE>

      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 Indenture Trustee, the
Paying Agent and any agent of the Issuer 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 Indenture Trustee, the
Paying Agent nor any agent of the Issuer 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 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;

                                       37
<PAGE>

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

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

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

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

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

      Section 4.08 Definitive Bonds. If (i) the Indenture Trustee determines
that the Depository is no longer willing or able to properly discharge its
responsibilities with respect to the Bonds and the Indenture Trustee is unable
to locate a qualified successor, (ii) the Indenture Trustee elects to terminate
the book-entry system through the Depository or (iii) after the occurrence of an
Event of Default, Beneficial Owners of Bonds representing beneficial interests
aggregating at least a majority of the Bond Principal Balances of the Bonds
advise the Depository in writing that the continuation of a book-entry system
through the Depository is no longer in the best interests of the Beneficial
Owners, then the Depository shall notify all Beneficial Owners and the Indenture
Trustee of the occurrence of any such event and of the availability of
Definitive Bonds to Beneficial Owners requesting the same. Upon surrender to the
Indenture Trustee of the typewritten Bonds representing the Book-Entry Bonds by
the Depository, accompanied by registration instructions, the Issuer shall
execute and the Indenture Trustee shall authenticate the Definitive Bonds in
accordance with the instructions of the Depository. None of the Issuer, the Bond
Registrar or the Indenture Trustee shall be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be protected in
relying on, such instructions. Upon the issuance of Definitive Bonds, the
Indenture Trustee shall recognize the Holders of the Definitive Bonds as
Bondholders.

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

      Section 4.10 Satisfaction and Discharge of Indenture. This Indenture shall
cease to be of further effect with respect to the Bonds except as to (i) rights
of registration of transfer and exchange, (ii) substitution of mutilated,
destroyed, lost or stolen Bonds, (iii) rights of Bondholders (and the Bond
Insurer, as subrogee of the Class 2-A 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), (vi) the
right of the Derivative Contract Counterparty to receive the Net Derivative Fee
and (vii) the rights of Bondholders as beneficiaries hereof with respect to the
property so deposited with the Indenture Trustee payable to all or any of them,
and the Indenture Trustee, on demand of and at the expense of the Issuer, shall
execute proper instruments acknowledging satisfaction and discharge of this
Indenture with respect to the Bonds and shall release and deliver the Collateral
to or upon the order of the Issuer, when

            (A) either

            (1) all Bonds theretofore authenticated and delivered (other than

      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

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

and the Issuer, in the case of a. or b. above, has irrevocably deposited or
caused to be irrevocably deposited with the Indenture Trustee cash or direct
obligations of or obligations guaranteed by the United States of America (which
will mature prior to the date such amounts are payable), in trust for such

      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, as the Indenture
Trustee may determine, to the Holders of Securities, of all sums due and to

      Section 4.12 [Reserved].

      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 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

surrender for cancellation of any one or more temporary Bonds, the Issuer shall
execute and the Indenture Trustee shall authenticate and make available for
delivery, in exchange therefor, Definitive Bonds of authorized denominations and
of like tenor, class and aggregate principal amount. Until so exchanged, such
temporary Bonds shall in all respects be entitled to the same benefits under
this Indenture as Definitive Bonds.

      Section 4.15 Representation Regarding ERISA. By acquiring a Class 1-A-1,
Class 1-A-2, Class 1-A-3 or Class 2-A Bond or interest therein, each Holder of
such Bond or Beneficial Owner of any such interest will be deemed to represent
that either (1) it is not acquiring such Bond with Plan Assets or (2) (A) the
acquisition, holding and transfer of such Bond will not give rise to a nonexempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code
and (B) the Bonds are rated investment grade or better and such purchaser agrees
to treat them as indebtedness for federal income tax purposes. Alternatively,
regardless of the rating of such Bonds, such person may provide the Indenture
Trustee and the Owner Trustee with an opinion of counsel, which opinion of
counsel will not be at the expense of the Issuer, the Seller, the Depositor, any
Underwriter, the Owner Trustee, the Indenture Trustee, the Master Servicer or
any successor servicer, which opines that the acquisition, holding and transfer
of such Bond or interest therein is permissible under applicable law, will not
constitute or result in a non-exempt prohibited transaction under ERISA or
Section 4975 of the Code and will not subject the Issuer, the Seller, the
Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the Master
Servicer or any successor servicer to any obligation in addition to those
undertaken in the Indenture.

                              Default and Remedies

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

      Section 5.02 Acceleration of Maturity; Rescission and Annulment. If an
Event of Default should occur and be continuing, then and in every such case the
Indenture Trustee at the written direction of the Holders of Bonds representing
not less than a majority of the aggregate Bond Principal Balance of the Bonds
may declare the Bonds to be immediately due and payable, by a notice in writing
to the Issuer (and to the Indenture Trustee if such notice is given by
Bondholders), and upon any such declaration the unpaid Bond Principal Balance of
the Class A Bonds and Class M 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, Holders of the Bonds representing not
less than a majority of the aggregate Bond Principal Balance of the Bonds, by
written notice to the Issuer and the Indenture Trustee, may waive the related
Event of Default and rescind and annul such declaration and its consequences if

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

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

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

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

                  (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.

                                       42
<PAGE>

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 Holders of a majority of the aggregate Bond Principal
Balances of the Bonds, pay to the Indenture Trustee, for the benefit of the
Holders of Bonds, the whole amount then due and payable on the Bonds for
principal and interest, with interest at the applicable Bond Interest Rate upon
the overdue principal, and in addition thereto such further amount as shall be
sufficient to cover the costs and expenses of collection, including the
reasonable compensation, expenses, disbursements and advances of the Indenture
Trustee and its agents and counsel.

      (b) In case the Issuer shall fail forthwith to pay such amounts upon such
demand, the Indenture Trustee, in its own name and as trustee of an express
trust, 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, 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, by such
appropriate Proceedings, as directed in writing by Holders of a majority of the
aggregate Bond Principal Balances of the Bonds, 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, as directed in writing by Holders
of a majority of the aggregate Bond Principal Balances of the Bonds,
irrespective of whether the principal of any Bonds shall then be due and payable
as therein expressed or by declaration or otherwise and irrespective of whether
the Indenture Trustee shall have made any demand pursuant to the provisions of
this Section, shall be entitled and empowered, by intervention in such
Proceedings or otherwise:

                                       43
<PAGE>

                  (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) 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 and of the
      Indenture Trustee on their behalf, and

                  (iv) to file such proofs of claim and other papers or
      documents as may be necessary or advisable in order to have the claims of
      the Indenture Trustee or the Holders of 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 and, in the event that the Indenture Trustee
shall consent to the making of payments directly to such Bondholders, to pay to
the Indenture Trustee such amounts as shall be sufficient to cover reasonable
compensation to the Indenture Trustee, each predecessor Indenture Trustee and
their respective agents, attorneys and counsel, and all other expenses and
liabilities incurred, and all advances made, by the Indenture Trustee and each
predecessor Indenture Trustee and all amounts due to the Bond Insurer.

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

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

                                       44

      (g) In any Proceedings brought by the Indenture Trustee (and also any
Proceedings involving the interpretation of any provision of this Indenture to
which the Indenture Trustee shall be a party), the Indenture Trustee shall be
held to represent all the Holders of the 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, and shall, at the written direction of
the Holders of a majority of the aggregate Bond Principal Balances of the Bonds,
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 enforce any judgment obtained, and collect from the Issuer and
      any other obligor upon such Bonds monies adjudged due;

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

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

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

provided, however, that the Indenture Trustee may not sell or otherwise
liquidate the Trust Estate following an Event of Default, unless (A) the
Indenture Trustee obtains the consent of the Holders of 100% of the aggregate
Bond Principal Balance of the Bonds, (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 such Bonds for principal
and interest and to reimburse the Bond Insurer for any amounts drawn under the
Bond Insurance Policy and any other amounts due to the Bond Insurer under the
Bond Insurance Policy 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 applicable 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 of a majority of the aggregate Bond Principal Balance
of the Bonds. In determining such sufficiency or insufficiency with respect to
clause (B) and (C), the Indenture Trustee may, but need not, obtain and rely
upon an opinion (obtained at the expense of the Trust) of an Independent
investment banking or accounting firm of national reputation as to the
feasibility of such proposed action and as to the sufficiency of the Trust
Estate for such purpose. Notwithstanding the foregoing, so long as an Event of
Servicer Termination has not occurred, any Sale of the Trust Estate shall be
made subject to the continued servicing of the Mortgage Loans by the Master
Servicer as provided in the Servicing Agreement.

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

                                       45

      Insurer under the Bond Insurance Policy (including any Premium Amount not
      paid pursuant to clause THIRD above);

            SEVENTH: to the Bondholders, first, to the Class 1-A-1, Class 1-A-2

            NINTH: to the payment of the remainder, if any to the Certificate
      Paying Agent on behalf of the Issuer or to any other person legally

payment to Bondholders pursuant to this Section 5.04. 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 elect to take and maintain possession of the
Trust Estate. It is the desire of the parties hereto and the Bondholders that
there be at all times sufficient funds for the payment of principal of and
interest on the Bonds and other obligations of the Issuer, including payment to
the Bond Insurer, and the Indenture Trustee, unless directed otherwise by the
Bond Insurer, shall take such desire into account when determining whether or
not to take and maintain possession of the Trust Estate. In determining whether
to take and maintain possession of the Trust Estate, the Indenture Trustee may,
but need not, obtain and rely upon an opinion of an Independent investment
banking or accounting firm of national reputation as to the feasibility of such
proposed action and as to the sufficiency of the Trust Estate for such purpose.

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

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

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

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

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

                                       47
<PAGE>

                  (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.

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 or to such
Bondholder, then and in every such case the Issuer, the Indenture Trustee and
the Bondholders shall, subject to any determination in such Proceeding, be
restored severally and respectively to their former positions hereunder, and
thereafter all rights and remedies of the Indenture Trustee 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 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 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 or to the Bondholders may be exercised from time to time, and as often
as may be deemed expedient, by the Indenture Trustee or by the Bondholders, as
the case may be.

      Section 5.11 Control By Bondholders. The Holders of a majority of the
aggregate Bond Principal Balances of Bonds shall have the right 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) any direction to the Indenture Trustee to sell or
      liquidate the Trust Estate shall be by Holders of Bonds representing not
      less than 100% of the Bond Principal Balances of the Bonds; and

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

Notwithstanding the rights of Bondholders set forth in this Section 5.11 the
Indenture Trustee need not take any action that it determines might involve it
in liability.

      Section 5.12 Waiver of Past Defaults. Prior to the declaration of the
acceleration of the maturity of the Bonds as provided in Section 5.02 hereof,
the Holders of Bonds representing not less than a majority of the aggregate Bond
Principal Balance of the Bonds may waive any past Event of Default and its
consequences except an Event of Default (a) with respect to payment of principal
of or interest on any of 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 obligations under the Bond Insurance
Policy. In the case of any such waiver, the Issuer, the Indenture Trustee and
the Holders of the Bonds shall be restored to their former positions and rights
hereunder, respectively, but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereto.

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

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

                                       49
<PAGE>

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 Bond Insurance Policy shall have been paid. The
Indenture Trustee may from time to time postpone any public Sale by public
announcement made at the time and place of such Sale. The Indenture Trustee
hereby expressly waives its right to any amount fixed by law as compensation for
any Sale.

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

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

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

            (3) the Indenture Trustee determines that the conditions for
      retention of the Trust Estate set forth in Section 5.05 hereof cannot be
      satisfied (in making any such determination, the Indenture Trustee may
      rely upon an opinion of an Independent investment banking firm obtained
      and delivered as provided in Section 5.05 hereof), the Holders of Bonds
      representing at least 100% 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 Holders representing at least 66-2/3% of the Bond Principal
Balances of the Bonds have otherwise consented or directed the Indenture
Trustee, at any public Sale of all or any portion of the Trust Estate at which a
minimum bid equal to or greater than the amount described in paragraph (2) of
subsection (b) of this Section 5.15 has not been established by the Indenture
Trustee and no Person bids an amount equal to or greater than such amount, the
Indenture

                                       50
<PAGE>

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, 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 distributable
      to the Bond Insurer as a result of such Sale in accordance with Section
      5.04(b) hereof on the Payment Date next succeeding the date of such Sale
      and (B) the expenses of the Sale and of any Proceedings in connection
      therewith which are reimbursable to it, without being required to produce
      the Bonds in order to complete any such Sale or in order for the net Sale
      price to be credited against such Bonds, and any property so acquired by
      the Indenture Trustee shall be held and dealt with by it in accordance
      with the provisions of this Indenture;

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

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

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

      Section 5.16 Action on Bonds. The Indenture Trustee's right to seek and
recover judgment on the Bonds or under this Indenture shall not be affected by
the seeking, obtaining or application of any other relief under or with respect
to this Indenture. Neither the lien of this Indenture nor any rights or remedies
of the Indenture Trustee or the Bondholders shall be impaired by the recovery of
any judgment by the Indenture Trustee against the Issuer or by the levy of any
execution under such judgment upon any portion of the Trust Estate or upon any
of the assets of the Issuer. Any money

                                       51
<PAGE>

or property collected by the Indenture Trustee shall be applied in accordance
with Section 5.04(b) hereof.

      Section 5.17 Performance and Enforcement of Certain Obligations. (a)
Promptly following a request from the Indenture Trustee to do so, the Issuer in
its capacity as holder of the Mortgage Loans, shall take all such lawful action
as the Indenture Trustee may request to cause the Issuer to compel or secure the
performance and observance by the Seller and the Master Servicer, as applicable,
of each of their obligations to the Issuer under or in connection with the
Mortgage Loan Purchase Agreement, any Group 1 or Group 2 Subsequent Mortgage
Loan Purchase Agreement and the Servicing Agreement, and to exercise any and all
rights, remedies, powers and privileges lawfully available to the Issuer under
or in connection with the Mortgage Loan Purchase Agreement, any Group 1 or Group
2 Subsequent Mortgage Loan Purchase Agreement and the Servicing Agreement to the
extent and in the manner directed by the Indenture Trustee, as pledgee of the
Mortgage Loans, including the transmission of notices of default on the part of
the Seller or the Master Servicer thereunder and the institution of legal or
administrative actions or proceedings to compel or secure performance by the
Seller or the Master Servicer of each of their obligations under the Mortgage
Loan Purchase Agreement, any Group 1 or Group 2 Subsequent Mortgage Loan
Purchase Agreement and the Servicing Agreement.

      (b) The Indenture Trustee, as pledgee of the Mortgage Loans, may, and at

writing promptly thereafter)) of the Holders of 66-2/3% of the Bond Principal
Balances of the Bonds, shall exercise all rights, remedies, powers, privileges
and claims of the Issuer against the Seller or the Master Servicer under or in
connection with the Mortgage Loan Purchase Agreement, any Group 1 or Group 2
Subsequent Mortgage Loan Purchase Agreement and the Servicing Agreement,
including the right or power to take any action to compel or secure performance
or observance by the Seller or the Master Servicer, as the case may be, of each
of their obligations to the Issuer thereunder and to give any consent, request,
notice, direction, approval, extension or waiver under the Mortgage Loan
Purchase Agreement, any Group 1 or Group 2 Subsequent Mortgage Loan Purchase
Agreement and the Servicing Agreement, as the case may be, and any right of the
Issuer to take such action shall not be suspended.

                                   ARTICLE VI

                              The Indenture Trustee

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

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

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

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

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

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

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

                  (iii) the Indenture Trustee shall not be liable with respect
      to any action it takes or omits to take in good faith in accordance with a
      direction received by it from Bondholders or from the Issuer, which they
      are entitled to give under the Basic Documents.

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

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

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

                                       53
<PAGE>

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

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

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

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

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

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

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

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

      (g) The Indenture Trustee or its Affiliates are permitted to receive
additional compensation that could be deemed to be in the Indenture Trustee's
economic self-interest for (i) serving as investment adviser, administrator,
shareholder servicing agent, custodian or sub-custodian with respect to certain
of the Eligible Investments, (ii) using Affiliates to effect transactions in
certain Eligible Investments and (iii) effecting transactions in certain
Eligible Investments. Such compensation shall not be considered an amount that
is reimbursable or payable to the Indenture Trustee (i) as part of the Indenture
Trustee Fee, (ii) pursuant to Sections 3.05(d), 3.05(h), 5.04(b), 6.07 or
8.02(c) hereunder or (iii) out of Available Funds.

      Section 6.03 Individual Rights of Indenture Trustee. The Indenture Trustee
in its individual or any other capacity may become the owner or pledgee of Bonds
and may otherwise deal with the Issuer or its Affiliates with the same rights it
would have if it were not Indenture Trustee, subject

                                       54
<PAGE>

to the requirements of the Trust Indenture Act. Any Bond Registrar, co-registrar
or co-paying agent may do the same with like rights. However, the Indenture
Trustee must comply with Sections 6.11 and 6.12 hereof.

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

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

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

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

      Section 6.07 Compensation and Indemnity. The Issuer shall pay to the
Indenture Trustee on each Payment Date reasonable compensation for its services.
On each Payment Date, the Indenture Trustee shall pay itself from amounts on
deposit in the Payment Account for such Payment Date and all amounts owing to
the Indenture Trustee hereunder (including amounts owing from the Issuer for
indemnification and otherwise) in excess of such amount shall be paid solely as
provided in Section 3.05(d)(xii), Section 3.05(h)(xii) 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 against any and all
loss, liability or expense (including attorneys' fees) incurred by it in
connection with the administration of this Trust and the performance of its
duties hereunder. The Indenture Trustee shall notify the Issuer promptly of any
claim for which it may seek indemnity. Failure by the Indenture Trustee to so
notify the Issuer shall not relieve the Issuer of its obligations hereunder. The
Issuer shall defend any such claim, and the Indenture Trustee may have separate
counsel and the Issuer shall pay the fees and expenses of such counsel. The
Issuer is not obligated

                                       55
<PAGE>

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. Holders of a majority of Bond
Principal Balances of the Bonds may remove the Indenture Trustee by so notifying
the Indenture Trustee and may appoint a successor Indenture Trustee. The Issuer
shall, remove the Indenture Trustee if:

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

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

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

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

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

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

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

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

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

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

      Section 6.10 Appointment of Co-Indenture Trustee or Separate Indenture
Trustee. (a) Notwithstanding any other provisions of this Indenture, at any
time, for the purpose of meeting any legal requirement of any jurisdiction in
which any part of the Trust Estate may at the time be located, the Indenture
Trustee shall have the power and may execute and deliver all instruments to
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, such title to the Trust Estate, or any part hereof, and, subject to
the other provisions of this Section, such powers, duties, obligations, rights
and trusts as the Indenture Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 6.11 hereof.

      (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

      convey and confirm unto the Indenture Trustee any property subject or
      required to be subjected to the lien of this Indenture, or to subject to
      the lien of this Indenture additional property;

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

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

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

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

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

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

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

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

                                       67

supplement and to the effect that (i) such indenture supplement is permitted
hereunder and (ii) entering into such indenture supplement will not result in a
"substantial modification" of the Bonds under Treasury Regulation Section
1.1001-3 or adversely affect the status of the Bonds as indebtedness for federal
income tax purposes.

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

      (b) The Issuer and the Indenture Trustee, when authorized by an Issuer
Request, may, also without the consent of any of the Holders of the Bonds and
prior notice to the Rating Agencies, enter into an indenture or indentures
supplemental hereto for the purpose of adding any provisions to, or changing in
any manner or eliminating any of the provisions of, this Indenture or of
modifying in any manner the rights of the Holders of the 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 consent of the
Holders of not less than a majority of the Bond Principal Balance of each Class
of Bonds affected thereby, by Act (as defined in Section 10.03 hereof) of such
Holders delivered to the Issuer and the Indenture Trustee, enter into an
indenture or indentures supplemental hereto for the purpose of adding any
provisions to, or changing in any manner or eliminating any of the provisions
of, this Indenture or of modifying in any manner the rights of the Holders of
the Bonds under this Indenture; provided, however, that no such supplemental
indenture shall, without the consent of the Holder of each Bond affected
thereby:

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

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

                  (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";

                                       68
<PAGE>

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

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

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

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

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

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

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

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

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

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

                                       69
<PAGE>

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

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

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

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

                                    ARTICLE X

                                  Miscellaneous

      Section 10.01 Compliance Certificates and Opinions, etc. (a) Upon any
application or request by the Issuer to the Indenture Trustee to take any action
under any provision of this Indenture, the Issuer shall furnish to the Indenture
Trustee (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 an Officer's
Certificate certifying or stating the opinion of each person signing such
certificate as to the fair value (within 90 days prior to such deposit) to the
Issuer of the Collateral or other property or securities to be so deposited and
a report from a nationally recognized accounting firm verifying such value.

                  (ii) Whenever the Issuer is required to furnish to the
      Indenture Trustee 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

                                       71
<PAGE>

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

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

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

      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.

                                       72
<PAGE>

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

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

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

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

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

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

                  (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

                                       73
<PAGE>

      to the Issuer addressed to: Impac CMB Trust Series 2004-6, in care of
      Wilmington Trust Company, Rodney Square North, 1100 North Market Street,
      Wilmington, Delaware 19990- 0001, Attention: Corporate Trust
      Administration, or at any other address previously furnished in writing to
      the Indenture Trustee by the Issuer. The Issuer shall promptly transmit
      any notice received by it from the Bondholders to the Indenture Trustee;
      or

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

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

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

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

      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
PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

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

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

being understood that the Indenture Trustee and the Owner Trustee have no such
obligations in their individual capacity) and except that any such partner,
owner or beneficiary shall be fully liable, to the extent provided by applicable
law, for any unpaid consideration for stock, unpaid capital contribution or
failure to pay any installment or call owing to such entity. For all purposes of
this Indenture, in the performance of any duties or obligations of the Issuer
hereunder, the Owner Trustee shall be subject to, and entitled to the benefits

      Section 10.16 No Petition. The Indenture Trustee, by entering into this
Indenture, and each Bondholder, by accepting a Bond, hereby covenant and agree

public accountants, and to discuss the Issuer's affairs, finances and accounts

confidence all such information except to the extent disclosure may be required
by law (and all reasonable applications for confidential treatment are
unavailing) and except to the extent that the Indenture Trustee may reasonably
determine that such disclosure is consistent with its obligations hereunder.

                                   ARTICLE XI

                   Certain Matters Regarding the Bond Insurer

      Section 11.01 Rights of the Bond Insurer to Exercise the Rights of the
Class 2-A Bonds. By accepting its Bond, each Class 2-A Bondholder agrees that
unless an Bond Insurer Default exists, the Bond Insurer shall have the right to
exercise all consent, voting, direction and other control rights of the Class
2-A Bondholders under this Indenture without any further consent of the Class
2-A Bondholders.

      Section 11.02 Claims Upon the Bond Insurance Policy; Insurance Account.
(a) If, on the Business Day next succeeding the Determination Date, the Master
Servicer determines that (i) the funds that will be on deposit in the Payment
Account on the third Business Day prior to the related Payment Date, to the
extent payable to the Class 2-A Bondholders pursuant to Section 3.05, are
insufficient to pay the Accrued Bond Interest on the Class 2-A Bonds for such
Payment Date, net of any Prepayment Interest Shortfalls, Relief Act Shortfalls
or Basis Risk Shortfalls allocated to the Class 2-A Bonds, (ii) the principal
portion of any Realized Loss is allocated to the Class 2-A Bonds on such Payment
Date or (iii) the funds available in connection with an optional redemption of
the Bonds pursuant to Section 8.07 or on the Final Scheduled Payment Date will
be insufficient to reduce the Bond Principal Balance of the Class 2-A Bonds to
zero, the Master Servicer shall deliver to the Indenture Trustee not later than
1:00 p.m. New York City time on the Business Day next succeeding the
Determination Date a certificate signed by a Servicing Officer directing the
Indenture Trustee to draw on the Bond Insurance Policy and stating the amount to
be drawn and stating the Insured Amount for the Class 2-A Bonds, and the
Indenture Trustee shall give notice by telephone or telecopy of the aggregate
amount of such deficiency, confirmed in writing in the form set forth as Exhibit
A to the endorsement of the Bond Insurance Policy, to the Bond Insurer at or
before 12:00 noon, New York City time, on the Business Day prior to such Payment
Date. If, subsequent to such notice, and prior to payment by the Bond Insurer
pursuant to such notice, additional amounts are deposited in the Payment
Account, the Indenture Trustee shall reasonably promptly notify the Bond Insurer
and withdraw the notice or reduce the amount claimed, as appropriate.

      (b) The Indenture Trustee shall establish a separate special purpose trust
account for the benefit of Holders of the Class 2-A Bonds and the Bond Insurer
referred to herein as the "Insurance Account" over which the Indenture Trustee
shall have exclusive control and sole right of withdrawal. The Indenture Trustee
shall deposit any amount paid to it under the Bond Insurance Policy in the
Insurance Account and distribute such amount only for purposes of payment to
Holders of Class 2-A Bonds of the Insured Amount for which a claim was made.
Such amount may not be applied to satisfy any costs, expenses or liabilities of
the Master Servicer, the Indenture Trustee or the Trust Estate. Amounts paid
under the Bond Insurance Policy shall be transferred to the Payment Account in
accordance with the next succeeding paragraph and disbursed by the Indenture
Trustee to Holders of Class 2-A Bonds in accordance with Section 3.05 or Section
8.04, as applicable. It shall not be necessary for such payments to be made by
checks or wire transfers separate from the checks or wire transfers used to pay
the Insured Amount with other funds available to make such payment. However, the
amount of any payment of principal of or interest on the Class 2-A Bonds to be
paid from funds transferred from the Insurance Account shall be noted as
provided in paragraph (c) below and in the statement to be furnished to Holders
of the Bonds and Certificates

                                       77
<PAGE>

pursuant to Section 3.25. Funds held in the Insurance Account shall not be
invested by the Master Servicer.

      On any Payment Date with respect to which a claim has been made under the
Bond Insurance Policy, the amount of any funds received by the Indenture Trustee
as a result of any claim under the Bond Insurance Policy, to the extent required
to pay the Insured Amount on such Payment Date, shall be withdrawn by the
Indenture Trustee from the Insurance Account and deposited in the Payment
Account and applied by the Indenture Trustee, together with the other funds to
be distributed to the Class 2-A Bondholders pursuant to Section 3.05, directly
to the payment in full of the Insured Amount due on the Class 2-A Bonds. Any
funds remaining in the Insurance Account on the first Business Day following a
Payment Date shall be remitted by the Indenture Trustee to the Bond Insurer,
pursuant to the written instructions of the Bond Insurer, by the end of such
Business Day.

      (c) The Indenture Trustee shall keep a complete and accurate record of the
amount of interest and principal paid into the Insurance Account in respect of
any Class 2-A Bond from moneys received by the Indenture Trustee under the Bond
Insurance Policy. The Bond Insurer shall have the right to inspect such records
at reasonable times during normal business hours upon two Business Day's prior
written notice to the Indenture Trustee.

      Section 11.03 Effect of Payments by the Bond Insurer; Subrogation.
Anything herein to the contrary notwithstanding, for purposes of this Section
11.03, any payment with respect to principal of or interest on the Class 2-A
Bonds which is made with monies received pursuant to the terms of the Bond
Insurance Policy shall not be considered payment of the Class 2-A Bonds from the
Trust Estate. The Master Servicer and the Indenture Trustee acknowledge, and
each Holder by its acceptance of a Class 2-A Bond agrees, that without the need
for any further action on the part of the Bond Insurer, the Master Servicer, the
Indenture Trustee or the Certificate Registrar, to the extent the Bond Insurer
makes payments, directly or indirectly, on account of principal of or interest
on the Class 2-A Bonds to the Holders of such Bonds, the Bond Insurer will be
fully subrogated to, and each Class 2-A Bondholder and the Indenture Trustee
hereby delegate and assign to the Bond Insurer, to the fullest extent permitted
by law, the rights of such Holders to receive such principal and interest from
the Trust Estate; provided that the Bond Insurer shall be paid such amounts only
from the sources and in the manner explicitly provided for herein.

      The Indenture Trustee and the Master Servicer 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 interests under this Indenture without
limiting the rights or affecting the interests of the Holders as otherwise set
forth herein.

      Section 11.04 Notices and Information to the Bond Insurer. All notices,
statements, reports, certificates or opinions required by this Indenture to be
sent or made available to any other party hereto or to the Bondholders or
Certificateholders shall also be sent or made available to the Bond Insurer.

                                       78

      Section 11.05 Trustee to Hold Bond Insurance Policy. The Indenture Trustee
will hold the Bond Insurance Policy in trust as agent for the Class 2-A
Bondholders for the purpose of making claims thereon and distributing the
proceeds thereof. Neither the Bond Insurance Policy, nor the amounts paid on the
Bond Insurance Policy will constitute part of the Trust Estate. Each Class 2-A
Bondholder, by accepting its Bond, appoints the Indenture Trustee as
attorney-in-fact for the purpose of making claims on the Bond Insurance Policy.
The Indenture Trustee shall surrender the Bond Insurance Policy to the Bond
Insurer for cancellation upon the expiration of the term of the Bond Insurance
Policy as provided in the Bond Insurance Policy following the retirement of the
Class 2-A Bonds.

      Impac CMB Trust Series 2004-6 (the "Issuer"), a Delaware statutory trust,
for value received, hereby promises to pay to Cede & Co. or registered assigns,
the principal sum of ($_________________) in monthly installments on the
twenty-fifth day of each month or, if such day is not a Business Day, the next
succeeding Business Day (each a "Payment Date"), commencing in July 2003 and
ending on or before the Payment Date occurring in _____________ (the "Final
Scheduled Payment Date") and to pay interest on the Bond Principal Balance of
this Bond (this "Bond") outstanding from time to time as provided below.

      This Bond is one of a duly authorized issue of the Issuer's Collateralized
Asset-Backed Bonds, Series 2004-6 (the "Bonds"), issued under an Indenture dated
as of June 29, 2004 (the "Indenture"), between the Issuer and Wells Fargo Bank,
N.A., as indenture trustee (the "Indenture Trustee", which term includes any
successor Indenture Trustee under the Indenture), 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 certificate guaranty
insurance policy (the "Bond Insurance Policy") issued thereby, has
unconditionally and irrevocably guaranteed the payment of the Insured Amount
with respect to the Class 2-A Bonds with respect to each Payment Date. Such Bond
Insurance Policy will not cover any Prepayment Interest Shortfalls, Relief Act
Shortfalls or Basis Risk Shortfall Carry- Forward Amount.]

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

                                      A-1-2
<PAGE>

and the aggregate amount of cumulative Realized Losses allocated to such Bond on
all prior Payment Dates.

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

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

      The Bonds are subject to redemption in whole, but not in part, by the
Majority Certificateholder on any Payment Date on or after the earlier of (i)
the Payment Date on which the aggregate Stated Principal Balance of the Mortgage
Loans as of the end of the prior Due Period is less than or equal to 20% of the
aggregate Stated Principal Balance of the Mortgage Loans as of Cut-off Date and
the aggregate amount deposited into the Group 1 Pre-Funding Account and Group 2
Pre-Funding Account on the Closing Date and (ii) the Payment Date in July 2014.

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

      Any payment of principal or interest payable on this Bond which is
punctually paid on the applicable Payment Date shall be paid to the Person in
whose name such Bond is registered at the close of business on the Record Date
for such Payment Date by check mailed to such person's address as it appears in
the Bond Register on such Record Date, except for the final installment of
principal and interest payable with respect to such Bond, which shall be payable
as provided below. Notwithstanding the foregoing, upon written request with
appropriate instructions by the Holder of this Bond delivered to the Indenture
Trustee at least five Business Days prior to the Record Date, any payment of
principal or interest, other than the final installment of principal or
interest, shall be made by wire transfer to an account in the United States
designated by such Holder. All [scheduled] 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

                                      A-1-3
<PAGE>

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

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

      The Holder of this Bond or Beneficial Owner of any interest herein is
deemed to represent that either (1) it is not acquiring the Bond with Plan
Assets or (2) (A) the acquisition, holding and transfer of a Bond will not give
rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section
4975 of the Code and (B) the Bonds are rated investment grade or better and such
person agrees to treat them as indebtedness for federal income tax purposes.
Alternatively, regardless of the rating of such Bonds, such person may provide
the Indenture Trustee and the Owner Trustee with an opinion of counsel, which
opinion of counsel will not be at the expense of the Issuer, the Seller, any
Underwriter, the Owner Trustee, the Indenture Trustee, the Depositor, the Master
Servicer or any successor servicer which opines that the acquisition, holding
and transfer of such Bond or interest therein is permissible under applicable
law, will not constitute or result in a non-exempt prohibited transaction under
ERISA or Section 4975 of the Code and will not subject the Issuer, the Seller,
the Depositor, any Underwriter, the Owner Trustee, the Indenture Trustee, the
Depositor, the Master Servicer or any successor servicer to any obligation in
addition to those undertaken in the Indenture.

      [Pursuant to the Indenture, unless a Bond Insurer Default (as defined in
the Indenture) exists (i) the Bond Insurer shall be deemed to be the holder of
the Class 2-A Bonds for certain purposes specified in the Indenture (other than
with respect to payment on the Class 2-A Bonds), and will be entitled to
exercise all rights of the Bondholders thereunder, including the rights of
Bondholders relating to the occurrence of, and the remedies with respect to, an
Event of Default, without the consent of such Bondholders, and (ii) the Trustee
may take actions which would otherwise be at its option or within its
discretion, including actions relating to the occurrence of, and the remedies
with respect to, an Event of Default, only at the direction, or with the
consent, of the Bond Insurer.]

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

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

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

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

      Impac CMB Trust Series 2004-6 (the "Issuer"), a Delaware statutory trust,
for value received, hereby promises to pay to Cede & Co. or registered assigns,
the principal sum of ______________________________ ($___________) in monthly
installments on the twenty-fifth day of each month or, if such day is not a
Business Day, the next succeeding Business Day (each a "Payment Date"),
commencing in July 2003 and ending on or before the Payment Date occurring in
_____________ (the "Final Scheduled Payment Date") and to pay interest on the
Bond Principal Balance of this Bond (this "Bond") outstanding from time to time
as provided below.

      This Bond is one of a duly authorized issue of the Issuer's Collateralized
Asset-Backed Bonds, Series 2004-6 (the "Bonds"), issued under an Indenture dated
as of June 29, 2004 (the "Indenture"), between the Issuer and Wells Fargo Bank,
N.A., as indenture trustee (the "Indenture Trustee", which term includes any
successor Indenture Trustee under the Indenture), to which Indenture and all
indentures supplemental thereto reference is hereby made for a statement of the
respective rights thereunder of the Issuer, the Indenture Trustee, and the
Holders of the Bonds and the terms upon which the Bonds are to be authenticated
and delivered. All terms used in this Bond which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

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

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

                                      A-2-2
<PAGE>

      The Bonds are subject to redemption in whole, but not in part, by the
Majority Certificateholder on any Payment Date on or after the earlier of (i)
the Payment Date on which the aggregate Stated Principal Balance of the Mortgage
Loans is less than or equal to 20% of aggregate Stated Principal Balance of the
Mortgage Loans as of Cut-off Date and the aggregate amount deposited into the
Group 1 Pre-Funding Account and Group 2 Pre-Funding Account on the Closing Date
and (ii) the Payment Date in July 2014.

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

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

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

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

                                      A-2-3
<PAGE>

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.

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

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

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

 (5) “Small business firm” means a small business concern as defined at section 2 of Pub. L.
85-536 (15 U.S.C. 632) and implementing regulations of the Administrator of the Small Business Administration. For the purpose of this clause, the size standards for small business concerns involved in Government procurement and subcontracting at 13

 (6) “Subject invention” means any invention of the contractor conceived or first actually reduced to practice in the performance of work under this contract, provided that in the case of a variety of plant, the date of
determination (as defined in section 41(d) of the Plant Variety Protection Act, 7 U.S.C. 240l(d)) must also occur during the period of contract performance. 
  
 (b) Allocation of principal rights. The Contractor may retain, the entire right, title, and interest throughout the world to each subject invention subject to the
provisions of this clause and 35 U.S.C. 203. With respect to any subject invention in which the Contractor retains title, the Federal Government shall have a nonexclusive, nontransferable, irrevocable, paid-up license to practice or have practiced
for or on behalf of the United States the subject invention throughout the world. 
  
 (c) Invention disclosure, election of title, and filing of patent application by Contractor. 
  
 (1) The Contractor will disclose each subject invention to the Federal agency within 2 months after the inventor discloses it in writing to Contractor
personnel responsible for patent matters. The disclosure to the agency shall be in the form of a written report and shall identify the contract under which the invention was made and the inventor(s). It shall be sufficiently complete in technical
detail to convey a clear understanding to the extent known at the time of the disclosure, of the nature, purpose, operation, and the physical, chemical, biological or electrical characteristics of the invention. The disclosure shall also identify
any publication, on sale or public use of the invention and whether a manuscript describing the invention has been submitted for publication and, if so, whether it has been accepted for publication at the time of disclosure. In addition, after
disclosure to the agency, the Contractor will promptly notify the agency of the acceptance of any manuscript
describing the invention for publication or of any on sale or public use planned by the Contractor. 
  
 (2) The Contractor will elect in writing whether or not to retain title to any such invention by notifying the Federal agency within 2 years of disclosure
to the Federal agency. However, in any case where publication, on sale or public use has initiated the 1-year statutory period wherein valid patent protection can still be obtained in the United States, the period for election of title may be
shortened by the agency to a date that is no more than 60 days prior to the end of the statutory period. 
  
 (3) The Contractor will file its initial patent application on a subject invention to which it elects to retain title within 1 year after election of
title or, if earlier, prior to the end of any statutory period wherein valid patent protection can be obtained in the United States after a publication, on sale, or public use. The Contractor will file patent applications in additional countries or
international patent offices within either 10 months of the corresponding initial patent application or 6 months from the date permission is granted by the Commissioner of Patents and Trademarks to file foreign patent applications where such filing
has been prohibited by a Secrecy Order. 
  
 (4) Requests for
extension of the time for disclosure election, and filing under subparagraphs (c)(1), (2), and (3) of this clause may, at the discretion of the agency, be granted. 
  
 (d) Conditions when the Government may obtain title. The Contractor will convey to the Federal agency, upon written request, title to
any subject invention— 
  
 (1) If the Contractor fails to
disclose or elect title to the subject invention within the times Specified in paragraph (c) of this clause, or elects not to retain title; provided, that the agency may only request title within 60 days after learning of the failure of the
Contractor to disclose or elect within the specified times.

 (2) In those countries in which the Contractor fails to file patent applications within the times
specified in paragraph (c) of this clause; provided, however, that if the Contractor has filed a patent application in a country after the times specified in paragraph (c) of this clause, but prior to its receipt of the written request of the
Federal agency, the Contractor shall continue to retain title in that country. 
  
 (3) In any country in which the Contractor decides not to continue the prosecution of any application for, to pay the maintenance fees on, or defend in reexamination or opposition proceeding on, a patent on a subject
invention. 
  
 (e) Minimum rights to Contractor and protection of the Contractor
right to file. 
  
 (1) The Contractor will retain a nonexclusive
royalty-free license throughout the world in each subject invention to which the Government obtains title, except if the Contractor fails to disclose the invention within the times specified in paragraph (c) of this clause. The Contractor’s
license extends to its domestic subsidiary and affiliates, if any, within the corporate structure of which the Contractor is a party and includes the right to grant sublicenses of the same scope to the extent the Contractor was legally obligated to
do so at the time the contract was awarded. The license is transferable only with the approval of the Federal agency, except when transferred to the successor of that part of the Contractor’s business to which the invention pertains.

  
 (2) The Contractor’s domestic license may be revoked or
modified by the funding Federal agency to the extent necessary to achieve expeditious practical application of subject invention pursuant to an application for an exclusive license submitted in accordance with applicable provisions at 37 CFR Part
404 and agency licensing regulations (if any). This license will not be revoked in that field of use or the geographical areas in which the Contractor has achieved practical application and continues to make the benefits of the invention reasonably
accessible to the public. The license in any foreign country may be revoked or modified at the discretion of the funding Federal agency to the extent the Contractor, its licensees, or the domestic subsidiaries or affiliates have failed to achieve
practical application in that foreign country. 
  
 (3) Before
revocation or modification of the license, the funding Federal agency will furnish the Contractor a written notice of its intention to revoke or modify the license, and the Contractor will be allowed 30 days (or such other time as may be authorized
by the funding Federal agency for good cause shown by the Contractor) after the notice to show cause why the license should not be revoked or modified. The Contractor has the right to appeal, in accordance with applicable regulations in 37 CFR Part
404 and agency regulations, if any, concerning the licensing of Government-owned inventions, any decision concerning the revocation or modification of the license. 
  
 (f) Contractor action to protect the Government’s interest. 
  
 (1) The Contractor agrees to execute or to have executed and promptly deliver to the Federal agency all instruments
necessary to (i) establish or confirm the rights the Government has throughout the world in those subject inventions to which the Contractor elects to retain title, and (ii) convey title to the Federal agency when requested under paragraph (d) of
this clause and to enable the Government to obtain patent protection throughout the world in that subject invention. 
  
 (2) The Contractor agrees to require, by written agreement, its employees, other than clerical and nontechnical employees, to disclose promptly in writing
to personnel identified as responsible for the administration of patent matters and in a format suggested by the Contractor each subject invention made under contract in order that the Contractor can comply with the disclosure provisions of
paragraph (c) of this clause, and to execute all papers necessary to file patent applications on subject inventions and to establish the Government’s rights in the subject inventions. This disclosure format should require, as a minimum, the
information required by subparagraph (c)(1) of this clause. The Contractor shall instruct such employees, 

  

 17 of 25 
 UNCLASSIFIED 
  
 MODIFICATION P00012 TO

 UNCLASSIFIED 
  

 
through employee agreements or other suitable educational programs, on the importance of reporting inventions in sufficient time to permit the filing of
patent applications prior to U.S. or foreign statutory bars. 
  
 (3) The Contractor will notify the Federal agency of any decisions not to continue the prosecution of a patent application, pay maintenance fees, or defend in a reexamination or opposition proceeding on a patent, in any country, not less
than 30 days before the expiration of the response period required by the relevant patent office. 
  
 (4) The Contractor agrees to include, within the specification of any United States patent application and any patent, issuing thereon covering a subject
invention, the following statement, “This invention was made with Government support under (identify the contract) awarded by (identify the Federal agency). The Government has certain rights in the invention.” 
  
 (g) Subcontracts. 
  
 (1) The Contractor will include this clause, suitably modified to identify the parties, in al subcontracts, regardless of
tier, for experimental, developmental, or research work to be performed by a small business firm or domestic nonprofit organization. The subcontractor will retain all rights provided for the Contractor in this clause, and the Contractor will not, as
part of the consideration for awarding the subcontract, obtain rights in the subcontractor’s subject inventions. 
  
 (2) The Contractor will include in all other subcontracts, regardless of tier, for experimental, developmental, or research work the patent rights clause
required by Subpart 27.3. 
  
 (3) In the case of
subcontracts, at any tier, the agency, subcontractor, and the Contractor agree that the mutual obligations of the parties created by this clause constitute a contract between the subcontractor and the Federal agency with respect to the matters
covered by the clause; provided, however, that nothing in this paragraph is intended to confer any jurisdiction under the Contract Disputes Act in connection with proceedings under paragraph (j) of this clause. 
  
 (h) Reporting on utilization of subject inventions. The Contractor agrees to submit,
on request, periodic reports no more frequently than annually on the utilization of a subject invention or on efforts at obtaining such utilization that are being made by the Contractor or its licensees or assignees. Such reports shall include
information regarding the status of development, date of first commercial sale or use, gross royalties received by the Contractor, and such other data and information as the agency may reasonably specify. The Contractor also agrees to provide
additional reports as may be requested by the agency in connection with any march-in proceeding undertaken by the agency in accordance with paragraph (j) of this clause. As required by 35 U.S.C. 202(c)(5), the agency agrees it will not disclose such
information to persons outside the Government without permission of the Contractor. 
  
 (i) Preference for United States industry. Notwithstanding any other provision of this clause, the Contractor agrees that neither it nor any assignee will grant to any person the exclusive right to use or sell any subject invention
in the United States unless such person agrees that any product embodying the subject invention or produced through the use of the subject invention will be manufactured substantially in the United States. However, in individual cases, the
requirement for such an agreement may be waived by the Federal agency upon a showing by the Contractor or its assignee that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be
likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible. 
  
 (j) March-in rights. The Contractor agrees that, with respect to any subject invention in which it has acquired title, the Federal agency has the right in
accordance with the procedures in 37 CFR 401.6 and any supplemental regulations of the agency to require the Contractor, an assignee or exclusive licensee of a subject invention to 

  

 18 of 25 
 UNCLASSIFIED 
  
 MODIFICATION P00012 TO

 [REDACTED] 000-01-C-0315 

 UNCLASSIFIED 
  

 
grant a nonexclusive, partially exclusive, or exclusive license in any field of use to a responsible applicant or applicants, upon terms that are reasonable
under the circumstances, and if the Contractor, assignee, or exclusive licensee refuses such a request the Federal agency has the right to grant such a license itself if the Federal agency determines that— 
  
 (1) Such action is necessary because the Contractor or assignee has not
taken, or is not expected to take within a reasonable time, effective steps to achieve practical application of the subject invention in such field of use; 
  
 (2) Such action is necessary to alleviate health or safety needs which are not reasonably satisfied by the Contractor, assignee, or their licensees;

  
 (3) Such action is necessary to meet requirements for public
use specified by Federal regulations and such requirements are not reasonably satisfied by the Contractor, assignee, or licensees; or 
  
 (4) Such action is necessary because the agreement required by paragraph (i) of this clause has not been obtained or waived or because a licensee of the
exclusive right to use or sell any subject invention in the United States is in breach of such agreement. 
  
 (k) Special provisions for contracts with nonprofit organizations. If the Contractor is a nonprofit organization, it agrees that — 
  
 (1) Rights to a subject invention in the United States may not be assigned without the approval of the Federal agency,
except where such assignment is made to an organization which has as one of its primary functions the management of inventions; provided, that such assignee will be subject to the same provisions as the Contractor; 
  
 (2) The Contractor will share royalties collected on a subject invention with
the inventor, including Federal employee co-inventors (when the agency deems it appropriate) when the subject invention is assigned in accordance with 35 U.S.C. 202(e) and 37 CFR 401.10; 
  
 (3) The balance of any royalties or income earned by the Contractor with respect to subject inventions, after payment of
expenses (including payments to inventors) incidental to the administration of subject inventions will be utilized for the support of scientific research or education; and 
  
 (4) It will make efforts that are reasonable under the circumstances to attract licensees of subject inventions that are
small business firms, and that it will give a preference to a small business firm when licensing a subject invention if the Contractor determines that the small business firm has a plan or proposal for marketing the invention which, if executed, is
equally as likely to bring the invention to practical application as any plans or proposals from applicants that are not small business firms; provided, that the Contractor is also satisfied that the small business firm has the capability and
resources to carry out its plan or proposal. The decision whether to give a preference in any specific case will be at the discretion of the contractor. However, the Contractor agrees that the Secretary of Commerce may review the Contractor’s
licensing program and decisions regarding small business applicants, and the Contractor will negotiate changes to its licensing policies, procedures, or practices with the Secretary of Commerce when the Secretary’s review discloses that the
Contractor could take reasonable steps to more effectively implement the requirements of this subparagraph (k)(4).

 UNCLASSIFIED 
  

 b) The “International System of Units” is as established by the General Conference of Weights and Measures
in 1960; it is also known as “System International (SI)” or “Metric System”; and it is interpreted for US usage by the Department of Commerce’s Interpretation of the International System of Units for the United States as
printed in Federal Register Volume 55, Page 52242, Dec. 20,1990, and supplemented for the Federal Government’s usage by the General Services Administration’s Federal Standard 376, Preferred Metric Units of General Use by the

 (b) The contractor shall continually evaluate the total level-of-effort
required and recommend to the Government changes thereto which are considered beneficial in attaining the overall objectives of this contract. In controlling the utilization of man-hours of effort, the contractor shall promptly notify the
contracting officer, in writing, when there is an indication that premature exhaustion of the total man-hours of effort is predicted. 
  
 (c) It is understood and agreed that the rate of man-hours per month may fluctuate in pursuit of the technical objective; however, such fluctuations will be controlled to
