           This Pooling and Servicing Agreement (this "Agreement"), dated and
effective as of __________ 1, 200_, is entered into among Impac Secured Assets
Corp., as depositor (the "Depositor"), [NAME OF MASTER SERVICER] [IMPAC FUNDING
CORPORATION], as master servicer (the "Master Servicer"), and [NAME OF TRUSTEE],
as trustee (the "Trustee").

                              PRELIMINARY STATEMENT

           The Depositor intends to sell pass-through certificates
(collectively, the "Certificates"), to be issued hereunder in multiple classes,
which in the aggregate will evidence the entire beneficial ownership interest in
the Trust Fund created hereunder. The Certificates will consist of nineteen
Classes of certificates, designated as (i) the Class A Certificates, (ii) the
Class M Certificates, (iii) the Class B Certificates, (iv) the Class P
Certificates, (v) the Class C Certificates and (vi) the Class R Certificates.

                                     REMIC 1

           As provided in this Agreement, the Trustee will make an election to
treat the segregated pool of assets consisting of the Mortgage Loans and certain
other related assets subject to this Agreement as a real estate mortgage
investment conduit (a "REMIC") for federal income tax purposes, and such
segregated pool of assets will be designated as "REMIC 1." The Class R-1
Interest will represent the sole Class of "residual interests" in REMIC 1 for
purposes of the REMIC Provisions (as defined in this Agreement) under federal
income tax law. The following table irrevocably sets forth the designation, the
Uncertificated REMIC 1 Pass-Through Rate, the initial Uncertificated Principal
Balance, and solely for purposes of satisfying Treasury regulation Section
1.860G-1(a)(4)(iii), the "latest possible maturity date" for each of the REMIC 1
Regular Interests. None of the REMIC 1 Regular Interests will be certificated.

</TABLE>

         "Uncertificated REMIC Regular Interests": The REMIC 1 Regular Interests
and the REMIC 2 Regular Interests.

         "Uninsured Cause" Any cause of damage to property subject to a Mortgage
such that the complete restoration of such property is not fully reimbursable by
the hazard insurance policies or flood insurance policies required to be
maintained pursuant to Section 3.13.

         "United States Person" A citizen or resident of the United States, a
corporation or a partnership (including an entity treated as a corporation or
partnership for United States federal income tax purposes) created or organized
in, or under the laws of, the United States or any State thereof or the District
of Columbia (except, in the case of a partnership, to the extent provided in
regulations) provided that, for purposes solely of the restrictions on the
transfer of Class R Certificates, no partnership or other entity treated as a
partnership for United States federal income tax purposes shall be treated as a
United States Person unless all persons that own an interest in such partnership
either directly or through any entity that is not a corporation for United
States federal income tax purposes are required by the applicable operative
agreement to be United States Persons or an estate whose income is subject to
United States federal income tax regardless of its source, or a trust if a court
within the United States is able to exercise primary supervision over the
administration of the trust and one or more such United States Persons have the
authority to control all substantial decisions of the trust. To the extent
prescribed in regulations by the Secretary of the Treasury, which have not yet
been issued, a trust which was in existence on August 20, 1996 (other than a
trust treated as owned by the grantor under subpart E of part I of subchapter J
of chapter 1 of the Code), and which was treated as a United States person on
August 20, 1996 may elect to continue to be treated as a United States person
notwithstanding the previous sentence.

         "Unpaid Interest Shortfall Amount" For each Class of Offered
Certificates and the first Distribution Date, zero, and with respect to each
Class of Offered Certificates and any Distribution Date after the first
Distribution Date, the amount, if any, by which (a) the sum of (1) the Monthly
Interest Distributable Amount for such Class for the immediately preceding
Distribution Date and (2) the outstanding Unpaid Interest Shortfall Amount, if
any, for such Class for such preceding Distribution Date exceeds (b) the
aggregate amount distributed on such Class in respect of interest pursuant to
clause (a) of this definition on such preceding Distribution Date, plus interest
on the amount of interest due but not paid on such Class on such preceding
Distribution Date, to the extent permitted by law, at the Pass-Through Rate for
such Class for the related Accrual Period.

         "Voting Rights" The portion of the voting rights of all of the
Certificates which is allocated to any Certificate. At all times during the term
of this Agreement, (i) 98% of all Voting Rights will be allocated among the
Holders of the Class A Certificates, the Subordinate Certificates and the Class
C Certificates in proportion to the then outstanding Certificate Principal
Balances of their respective Certificates, (ii) 1% of all Voting Rights will be
allocated to the Holders of the Class P Certificates and (iii) 1% of all Voting
Rights will be allocated to the Holders of the Class R Certificates. The Voting
Rights allocated to any Class of Certificates shall be allocated among all
Holders of the Certificates of such Class in proportion to the outstanding
Percentage Interests in such Class represented thereby.

         "Weighted Average Net Mortgage Rate" The weighted average of the Net
Mortgage Rates of the Mortgage Loans, weighted on the basis of the Stated
Principal Balances thereof as of the close of business on the first day of the
calendar month preceding the month in which such Distribution Date occurs.

         Section 1.02. DETERMINATION OF LIBOR.

          LIBOR applicable to the calculation of the Pass-Through Rate on the
Offered Certificates for any Accrual Period will be determined on each LIBOR
Rate Adjustment Date.

         On each LIBOR Rate Adjustment Date, LIBOR shall be established by the
Trustee and, as to any Accrual Period, will equal the rate for one month United
States dollar deposits that appears on the Telerate Screen Page 3750 as of 11:00
a.m., London time, on such LIBOR Rate Adjustment Date. "Telerate Screen Page
3750" means the display designated as page 3750 on the Telerate Service (or such
other page as may replace page 3750 on that service for the purpose of
displaying London interbank offered rates of major banks). If such rate does not
appear on such page (or such other page as may replace that page on that
service, or if such service is no longer offered, LIBOR shall be so established
by use of such other service for displaying LIBOR or comparable rates as may be
selected by the Trustee after consultation with the Master Servicer), the rate
will be the Reference Bank Rate. The "Reference Bank Rate" will be determined on
the basis of the rates at which deposits in U.S. Dollars are offered by the
reference banks (which shall be any three major banks that are engaged in
transactions in the London interbank market, selected by the Trustee after
consultation with the Master Servicer) as of 11:00 a.m., London time, on the
LIBOR Rate Adjustment Date to prime banks in the London interbank market for a
period of one month in amounts approximately equal to the aggregate Certificate
Principal Balance of the Offered Certificates then outstanding. The Trustee will
request the principal London office of each of the reference banks to provide a
quotation of its rate. If at least two such quotations are provided, the rate
will be the arithmetic mean of the quotations rounded up to the next multiple of
1/16%. If on such date fewer than two quotations are provided as requested, the
rate will be the arithmetic mean of the rates quoted by one or more major banks
in New York City, selected by the Trustee after consultation with the Master
Servicer, as of 11:00 a.m., New York City time, on such date for loans in U.S.
Dollars to leading European banks for a period of one month in amounts
approximately equal to the aggregate Certificate Principal Balance of the
Offered Certificates then outstanding. If no such quotations can be obtained,
the rate will be LIBOR for the prior Distribution Date; provided however, if,
under the priorities described above, LIBOR for a Distribution Date would be
based on LIBOR for the previous Distribution Date for the third consecutive
Distribution Date, the Trustee shall select an alternative comparable index
after consultation with the Master Servicer (over which the Trustee has no
control), used for determining one-month Eurodollar lending rates that is

                          CONVEYANCE OF MORTGAGE LOANS;
                         ORIGINAL ISSUANCE OF CERTIFICATES

         Section 2.01. CONVEYANCE OF MORTGAGE LOANS.

         The Depositor, as of the Closing Date, and concurrently with the
execution and delivery hereof, does hereby assign, transfer, sell, set over and
otherwise convey to the Trustee without recourse all the right, title and
interest of the Depositor in and to the Mortgage Loans identified on the
Mortgage Loan Schedule (exclusive of any prepayment fees and late payment
charges received thereon) and all other assets included or to be included in the
Trust Fund for the benefit of the Certificateholders and the Certificate
Insurer, including the amount to be deposited by or on behalf of the Depositor
into the Net WAC Shortfall Reserve Fund. Such assignment includes all principal
and interest received by the Master Servicer on or with respect to the Mortgage
Loans (other than payment of principal and interest due on or before the Cut-off
Date).

         In connection with such transfer and assignment, the Depositor has
caused the Sponsor to deliver to, and deposit with the Custodian, as described
in the Mortgage Loan Purchase Agreement, with respect to each Mortgage Loan, the
following documents or instruments:

                  (i) the original Mortgage Note endorsed without recourse in
blank or to, "[NAME OF THE TRUSTEE], as trustee under the Pooling and Servicing
Agreement relating to Impac Secured Assets Corp., Mortgage Pass-Through
Certificates, Series 200_-_" with all intervening endorsements showing an
unbroken chain of endorsements from the originator to the Person endorsing it to
the Trustee or, with respect to any Mortgage Loan as to which the original
Mortgage Note has been permanently lost or destroyed and has not been replaced,
a Lost Note Affidavit;

                  (ii) the original recorded Mortgage, noting the presence of
the MIN of the Mortgage Loan and language indicating that the Mortgage Loan is a
MOM Loan if the Mortgage Loan is a MOM Loan, with evidence of recording
indicated thereon or, if the original Mortgage has not been returned from the
public recording office, a copy of the Mortgage certified by the Sponsor or the
public recording office in which such Mortgage has been recorded to be a true
and complete copy of the original Mortgage submitted for recording;

                  (iii) unless the Mortgage Loan is registered on the MERS(R)
System, a duly executed original Assignment of the Mortgage, without recourse in
blank or to, in recordable form to [NAME OF THE TRUSTEE], as trustee," or to
"[NAME OF THE TRUSTEE], as trustee for holders of Impac Secured Assets Corp.,
Mortgage Pass-Through Certificates, Series 200_-_";

                  (iv) the original recorded Assignment or Assignments of the
Mortgage showing an unbroken chain of assignment from the originator thereof to
the Person assigning it in blank or to the Trustee (or to MERS, if the Mortgage
Loan is registered on the MERS(R) System and noting the presence of a MIN) or,
if any such Assignment has not been returned from the applicable public
recording office, a copy of such Assignment certified by the Sponsor to be a
true and complete copy of the original Assignment submitted to the title
insurance company for recording;

                  (v) the original title insurance policy, or, if such policy
has not been issued, any one of an original or a copy of the preliminary title
report, title binder or title commitment on the Mortgaged Property with the
original policy of the insurance to be delivered promptly following the receipt
thereof;

                  (vi) a copy of the related hazard insurance policy; and

                  (vii) a true and correct copy of any assumption, modification,
consolidation or substitution agreement.

         The Sponsor is obligated as described in the Mortgage Loan Purchase
Agreement, with respect to the Mortgage Loans, to deliver to the Custodian: (a)
either the original recorded Mortgage, or in the event such original cannot be
delivered by the Sponsor, a copy of such Mortgage certified as true and complete
by the appropriate recording office, in those instances where a copy thereof
certified by the Sponsor was delivered to the Custodian pursuant to clause (ii)
above; and (b) either the original Assignment or Assignments of the Mortgage,
with evidence of recording thereon, showing an unbroken chain of assignment from
the originator to the Sponsor, or in the event such original cannot be delivered
by the Sponsor, a copy of such Assignment or Assignments certified as true and
complete by the appropriate recording office, in those instances where copies
thereof certified by the Sponsor were delivered to the Custodian pursuant to
clause (iv) above. However, pursuant to the Mortgage Loan Purchase Agreement
with respect to the Mortgage Loans, the Sponsor need not cause to be recorded
any assignment in any jurisdiction under the laws of which, as evidenced by an
Opinion of Counsel delivered by the Sponsor to the Trustee and the Rating
Agencies, the recordation of such assignment is not necessary to protect the
Trustee's interest in the related Mortgage Loan; provided, HOWEVER,
notwithstanding the delivery of any Opinion of Counsel, each assignment shall be
submitted for recording by the Sponsor in the manner described above, at no
expense to the Trust or the Trustee, upon the earliest to occur of: (i)
direction by the Holders of Certificates evidencing at least 25% of the Voting
Rights, (ii) the occurrence of a Event of Default, (iii) the occurrence of a
bankruptcy, insolvency or foreclosure relating to the Sponsor, (iv) the
occurrence of a servicing transfer as described in Section 7.02 hereof and (v)
if the Sponsor is not the Master Servicer and with respect to any one
assignment, the occurrence of a bankruptcy, insolvency or foreclosure relating
to the Mortgagor under the related Mortgage.

         Notwithstanding anything to the contrary contained in this Section
2.01, in those instances where the public recording office retains the original
Mortgage after it has been recorded, the Sponsor shall be deemed to have
satisfied its obligations hereunder upon delivery to the Custodian of a copy of
such Mortgage certified by the public recording office to be a true and complete
copy of the recorded original thereof.

         If any Assignment is lost or returned unrecorded to the Custodian
because of any defect therein, the Sponsor is required, as described in the
Mortgage Loan Purchase Agreement with respect to the Mortgage Loans, to prepare
a substitute Assignment or cure such defect, as the case may be, and the Sponsor
shall cause such Assignment to be recorded in accordance with this section.

         The Sponsor is required as described in the Mortgage Loan Purchase
Agreement to exercise its best reasonable efforts to deliver or cause to be
delivered to the Custodian within 120 days of the Closing Date, with respect to
the Mortgage Loans, the original or a photocopy of the title insurance policy
with respect to each such Mortgage Loan assigned to the Trustee pursuant to this
Section 2.01.

         In connection with the assignment of any Mortgage Loan registered on
the MERS(R) System, the Sponsor further agrees that it will cause, at the
Sponsor's own expense, as of the Closing Date, the MERS(R) System to indicate
that such Mortgage Loans have been assigned by the Sponsor to the Trustee in
accordance with this Agreement for the benefit of the Certificateholders and the
Certificate Insurer by including (or deleting, in the case of Mortgage Loans
which are repurchased in accordance with this Agreement) in such computer files
(a) the code in the field which identifies the specific Trustee and (b) the code
in the field "Pool Field" which identifies the series of the Certificates issued
in connection with such Mortgage Loans. The Depositor further agrees that it
will not, and will not permit the Master Servicer to, and the Master Servicer
agrees that it will not, alter the codes referenced in this paragraph with
respect to any Mortgage Loan during the term of this Agreement unless and until
such Mortgage Loan is repurchased in accordance with the terms of this
Agreement.

         All original documents relating to the Mortgage Loans which are not
delivered to the Custodian are and shall be held by the Master Servicer in trust
for the benefit of the Trustee on behalf of the Certificateholders and the
Certificate Insurer.

         Except as may otherwise expressly be provided herein, none of the
Depositor, the Master Servicer or the Trustee shall (and the Master Servicer
shall ensure that no Sub-Servicer shall) assign, sell, dispose of or transfer
any interest in the Trust Fund or any portion thereof, or cause the Trust Fund
or any portion thereof to be subject to any lien, claim, mortgage, security
interest, pledge or other encumbrance.

         It is intended that the conveyance of the Mortgage Loans by the
Depositor to the Trustee as provided in this Section be, and be construed as, a
sale of the Mortgage Loans as provided for in this Section 2.01 by the Depositor
to the Trustee for the benefit of the Certificateholders and the Certificate
Insurer. It is, further, not intended that such conveyance be deemed a pledge of
the Mortgage Loans by the Depositor to the Trustee to secure a debt or other
obligation of the Depositor. However, in the event that the Mortgage Loans are
held to be property of the Depositor, or if for any reason this Agreement is
held or deemed to create a security interest in the Mortgage Loans, then it is
intended that, (a) this Agreement shall also be deemed to be a security
agreement within the meaning of Articles 8 and 9 of the New York Uniform
Commercial Code and the Uniform Commercial Code of any other applicable
jurisdiction; (b) the conveyance provided for in this Section shall be deemed to
be (1) a grant by the Depositor to the Trustee of a security interest in all of
the Depositor's right (including the power to convey title thereto), title and
interest, whether now owned or hereafter acquired, in and to (A) the Mortgage
Loans, including the Mortgage Notes, the Mortgages, any related Insurance
Policies and all other documents in the related Mortgage Files, (B) all amounts
payable to the holders of the Mortgage Loans in accordance with the terms
thereof and (C) all proceeds of the conversion, voluntary or involuntary, of the
foregoing into cash, instruments, securities or other property, including
without limitation all amounts from time to time held or invested in the
Certificate Account or the Custodial Account, whether in the form of cash,
instruments, securities or other property and (2) an assignment by the Depositor
to the Trustee of any security interest in any and all of the Sponsor's right
(including the power to convey title thereto), title and interest, whether now
owned or hereafter acquired, in and to the property described in the foregoing
clauses (1)(A) through (C); (c) the possession by the Trustee or any other
Custodian or agent of the Trustee of Mortgage Notes and such other items of
property as constitute instruments, money, negotiable documents or chattel paper
shall be deemed to be "possession by the secured party" or possession by a
purchaser or a person designated by such secured party, for purposes of
perfecting the security interest pursuant to the New York Uniform Commercial
Code and the Uniform Commercial Code of any other applicable jurisdiction
(including, without limitation, Sections 9-115, 9-305, 8-102, 8-301, 8-501 and
8-503 thereof); and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the Trustee
for the purpose of perfecting such security interest under applicable law. The
Depositor and the Trustee shall, to the extent consistent with this Agreement,
take such actions as may be necessary to ensure that, if this Agreement were
deemed to create a security interest in the Mortgage Loans and the REMIC 1
Regular Interests, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and will be maintained
as such throughout the term of the Agreement.

         Concurrently with the execution of this Agreement, the Swap Agreement
shall be delivered to the Supplemental Interest Trust Trustee. In connection
therewith, the Depositor hereby directs the Supplemental Interest Trust Trustee
(solely in its capacity as such) to execute and deliver the Swap Agreement.

         Section 2.02. ACCEPTANCE OF THE TRUST FUND BY THE TRUSTEE.

         The Custodian, with respect to the Mortgage Files held by it,
acknowledges receipt (subject to any exceptions noted in the Initial
Certification described below) on behalf of the Trustee, of the documents
referred to in Section 2.01 above and all other assets included in the
definition of "Trust Fund" and declares that it holds and will hold such
documents and the other documents delivered to it constituting the Mortgage
Files, and that it holds or will hold such other assets included in the
definition of "Trust Fund" (to the extent delivered or assigned to the Trustee),
in trust for the exclusive use and benefit of all present and future
Certificateholders.

         The Custodian agrees, for the benefit of the Certificateholders and the
Certificate Insurer, to review or cause to be reviewed on its behalf, each
Mortgage File on or before the Closing Date to ascertain that all documents
required to be delivered to it are in its possession, and the Custodian agrees
to execute and deliver, or cause to be executed and delivered, to the Depositor,
the Certificate Insurer and the Master Servicer on the Closing Date, with
respect to each Mortgage Loan, an Initial Certification in the form annexed
hereto as Exhibit C to the effect that, as to each Mortgage Loan listed in the
Mortgage Loan Schedule (other than any Mortgage Loan paid in full or any
Mortgage Loan specifically identified in such certification as not covered by
such certification), (i) all documents required to be delivered to it pursuant
to this Agreement with respect to such Mortgage Loan are in its possession, (ii)
such documents have been reviewed by it and appear regular on their face and
relate to such Mortgage Loan and (iii) based on its examination and only as to
the foregoing documents, the information set forth in items (i), (ii), (iii)(A),
(iv) and (v) of the definition of the "Mortgage Loan Schedule" accurately
reflects information set forth in the Mortgage File. None of the Custodian, the
Trustee or the Master Servicer shall be under any duty to determine whether any
Mortgage File should include any of the documents specified in clause (vi) or
(vii) of Section 2.01. None of the Custodian, the Trustee or the Master Servicer
shall be under any duty or obligation to inspect, review or examine said
documents, instruments, certificates or other papers to determine that the same
are genuine, enforceable or appropriate for the represented purpose or that they
have actually been recorded, or they are in recordable form or that they are
other than what they purport to be on their face.

         Within 90 days of the Closing Date, with respect to the Mortgage Loans,
the Trustee, or the Custodian on its behalf, shall deliver to the Depositor, the
Certificate Insurer and the Master Servicer a Final Certification in the form
annexed hereto as Exhibit D evidencing the completeness of the Mortgage Files,
with any applicable exceptions noted thereon, with respect to all of the
Mortgage Loans.

         If in the process of reviewing the Mortgage Files and preparing the
certifications referred to above the Custodian finds any document or documents
constituting a part of a Mortgage File to be missing or defective in any
material respect, the Custodian shall promptly notify the Sponsor, the Master
Servicer, the Certificate Insurer, the Trustee and the Depositor. The Trustee
shall promptly notify the Sponsor of such defect and request that the Sponsor
cure any such defect within 60 days from the date on which the Sponsor was
notified of such defect, and if the Sponsor does not cure such defect in all
material respects during such period, request on behalf of the
Certificateholders that the Sponsor purchase such Mortgage Loan from the Trust
Fund at the Purchase Price within 90 days after the date on which the Sponsor
was notified of such defect; provided that if such defect would cause the
Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or repurchase must occur within 90 days
from the date such breach was discovered. It is understood and agreed that the
obligation of the Sponsor to cure a material defect in, or purchase any Mortgage
Loan as to which a material defect in a constituent document exists shall
constitute the sole remedy respecting such defect available to the
Certificateholders the Certificate Insurer or the Trustee on behalf of
Certificateholders. The Purchase Price for the purchased Mortgage Loan shall be
deposited or caused to be deposited upon receipt by the Master Servicer in the
Custodial Account and, upon receipt by the Trustee of written notification of
such deposit signed by a Servicing Officer, the Custodian shall release or cause
to be released to the Sponsor the related Mortgage File and shall execute and
deliver such instruments of transfer or assignment, in each case without
recourse, as the Sponsor shall require as necessary to vest in the Sponsor
ownership of any Mortgage Loan released pursuant hereto and at such time the
Trustee and the Custodian shall have no further responsibility with respect to
the related Mortgage File. In furtherance of the foregoing, if the Sponsor is
not a member of MERS and the Mortgage is registered on the MERS(R) System, the
Master Servicer, at its own expense and without any right of reimbursement,
shall cause MERS to execute and deliver an assignment of the Mortgage in
recordable form to transfer the Mortgage from MERS to the Sponsor and shall
cause such Mortgage to be removed from registration on the MERS(R) System in
accordance with MERS' rules and regulations.

Agreement respecting a breach of any of the representations, warranties and
covenants contained in the Mortgage Loan Purchase Agreement.

         (b) The Depositor hereby represents and warrants to the Master Servicer

hereto.

         It is understood and agreed that the representations and warranties set
forth in this Section 2.03(b) shall survive delivery of the respective Mortgage
Files to the Custodian, on behalf of the Trustee.

         Upon discovery by either the Depositor, the Master Servicer, the
Certificate Insurer or the Trustee of a breach of any representation or warranty
