     The Trustee on behalf of the Trust shall make an election for the assets
constituting REMIC IB to be treated for federal income tax purposes as a REMIC.

"regular interests" in such REMIC and the Class R-IB Interest will be designated
the "residual interests" in such REMIC.

     The Trustee on behalf of the Trust shall make an election for the assets

On the Startup Day, the REMIC II Regular Interests will be designated "regular
interests" in such REMIC and the Class R-II Interest will be designated the

     The Trustee on behalf of the Trust shall make an election for the assets
constituting REMIC III to be treated for federal income tax purposes as a REMIC.

     Whenever used in this Agreement, the following words and phrases, unless
otherwise expressly provided or unless the context otherwise requires, shall
have the meanings specified in this Article.

     ACCEPTED MASTER SERVICING PRACTICES: With respect to any Mortgage Loan, as
applicable, either (a) those customary mortgage servicing practices of prudent
mortgage servicing institutions that master service mortgage loans of the same
type and quality as such Mortgage Loan in the jurisdiction where the related
Mortgaged Property is located, to the extent applicable to the Trustee (except
in its capacity as successor to the Master Servicer), or (b) with respect to the
Master Servicer, as provided in this Agreement or, with respect to any
subservicer, as provided in the related Subservicing Agreement, but, in each
case, in no event below the standard set forth in clause (a).

     ACCOUNT: The Distribution Account or the Protected Accounts as the context
may require.

     ACCRUED CERTIFICATE INTEREST: For any Certificate for any Distribution
Date, the interest accrued during the related Interest Accrual Period at the
applicable Pass-Through Rate on the Current Principal Amount of such Certificate
immediately prior to such Distribution Date, calculated on the basis of a
360-day year consisting of twelve 30-day months, less (i) in the case of a
Senior Certificate, such Certificate's share of any Net Interest Shortfall and,
after the Cross-Over Date, the interest portion of any Realized Losses on the
Mortgage Loans allocated thereto in accordance with Section 6.02(g) and (ii) in
the case of a Subordinate Certificate, such Certificate's share of any Net
Interest Shortfall and the interest portion of any Realized Losses on the
Mortgage Loans allocated thereto in accordance with Section 6.02(g).

     AFFILIATE: As to any Person, any other Person controlling, controlled by or
under common control with such Person. "Control" means the power to direct the
management and policies of a Person, directly or indirectly, whether through
ownership of voting securities, by contract or otherwise. "Controlled" and

     AGREEMENT: This Pooling and Servicing Agreement and all amendments hereof
and supplements hereto.

     ALLOCABLE SHARE: With respect to each Class of Subordinate Certificates:

the Class Prepayment Distribution Trigger shall not be applicable) for which (x)
the related Class Prepayment Distribution Trigger has been satisfied on such
Distribution Date, the fraction, expressed as a percentage, the numerator of
which is the Current Principal Amount of such Class and the denominator of which

been satisfied on such Distribution Date, 0%; provided that if on a Distribution
Date, the Current Principal Amount of any Class of Subordinate Certificates for
which the related Class Prepayment Distribution Trigger was satisfied on such
Distribution Date is reduced to zero, any amounts distributed pursuant to this
clause (b), to the extent of such Class's remaining Allocable Share, shall be
distributed to the remaining Classes of Subordinate Certificates which satisfy
the related Class Prepayment Distribution Trigger and to the Class of
Subordinate Certificates having the lowest numerical designation in reduction of
their respective Current Principal Amounts in the order of their numerical Class
designations.

right, title and interest in, to and under the Mortgage Loans and other assets

or will, upon receipt of recording information relating to the Security
Instrument required to be included thereon, be delivered to recording offices
for recording and have not been returned to the Seller in time to permit their
delivery as specified above, the Seller may deliver a true copy thereof with a
certification by the Seller, on the face of such copy, substantially as follows:
"Certified to be a true and correct copy of the original, which has been
transmitted for recording"; (x) in lieu of the Security Instrument, assignment
to the Trustee or intervening assignments thereof, if the applicable
jurisdiction retains the originals of such documents (as evidenced by a
certification from the Seller to such effect) the Seller may deliver photocopies
of such documents containing an original certification by the judicial or other
governmental authority of the jurisdiction where such documents were recorded;
(y) in lieu of the original Mortgage Notes relating to any of the Group 1 or
Group 3 Mortgage Loans, an indemnity and lost note affidavit with a copy of the
original note, if available, will be provided (which lost note affidavit and
indemnity may be in the form of a blanket affidavit and indemnity covering all
Lost Notes as of the Closing Date so long as individual affidavits and
indemnities are provided to the Trustee within 30 days thereafter); and (z) the
Seller shall not be required to deliver intervening assignments or Mortgage Note
endorsements between the related Underlying Seller and EMC Mortgage Corporation,
between EMC Mortgage Corporation and the Seller, and between the Seller and the
Trustee; and provided, further, however, that in the case of Mortgage Loans
which have been prepaid in full after the Cut-off Date and prior to the Closing
Date, the Seller, in lieu of delivering the above documents, may deliver to the
Trustee a certification to such effect and shall deposit all amounts paid in
respect of such Mortgage Loans in the related Protected Account on the Closing
Date. The Seller shall deliver such original documents (including any original
documents as to which certified copies had previously been delivered) to the
Trustee promptly after they are received. The Seller shall cause, at its
expense, any available mortgages, intervening assignments, if any, assignments
of mortgage, and the assignment of the Security Instrument to the Trustee to be
recorded not later than 180 days after the Closing Date, unless such recordation
is not required by the Rating Agencies or an Opinion of Counsel has been
provided as set forth below in this Section 2.01(b). The Seller need not cause
to be recorded any assignment in any jurisdiction under any state other than
Maryland; provided, however, that each assignment shall be submitted for
recording by the Seller in the manner described above, at no expense to the
Trust or the Trustee upon the earliest to occur of: (i) reasonable direction by
the Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 25% of the Trust, (ii) the occurrence of an Event of
Default, (iii) the occurrence of a bankruptcy, insolvency or foreclosure
relating to the Seller and (iv) the occurrence of a servicing transfer as
described in Section 8.02 hereof. Notwithstanding the foregoing, if the Seller
fails to pay the cost of recording the assignments, such expense will be paid by
the Trustee and the Trustee shall be reimbursed for such expenses by the Trust
in accordance with Section 9.05.

     Section 2.02 ACCEPTANCE OF MORTGAGE LOANS BY TRUSTEE. (a) The Trustee
acknowledges the sale, transfer and assignment of the Trust to it by the Seller
and receipt of, subject to further review and the exceptions which may be noted
pursuant to the procedures described below, and declares that it holds, the
documents (or certified copies thereof) delivered to it pursuant to Section
2.01, and declares that it will continue to hold those documents and any
amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it as Trustee in trust for the use and benefit of all
present and future Holders of the Certificates. On the Closing Date, the Trustee
shall acknowledge with respect to each Mortgage Loan by an Initial Certification
substantially in the form of Exhibit H-1 to this Agreement receipt of the
Mortgage File, but without review of such Mortgage File, except to the extent
necessary to confirm that such Mortgage File contains the related Mortgage Note
or lost note affidavit. No later than 90 days after the Closing Date (or, with
respect to any Substitute Mortgage Loan, within five Business Days after the
receipt by the Trustee thereof), the Trustee agrees, for the benefit of the
Certificateholders, to review each Mortgage File delivered to it and to execute
and deliver, or cause to be executed and delivered, to the Seller, the Guarantor
and the Master Servicer an Interim Certification substantially in the form
annexed as Exhibit H-2 to this Agreement. In conducting such review, the Trustee
will ascertain whether all required documents have been executed and received,
and based on the Mortgage Loan Schedule, 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 the
Mortgage Loan Schedule. In performing any such review, the Trustee may
conclusively rely on the purported due execution and genuineness of any such
document and on the purported genuineness of any signature thereon. If the
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 or to appear to be defective on its face, the Trustee shall
promptly notify the Mortgage Loan Seller. In accordance with the Mortgage Loan
Purchase Agreement, the Mortgage Loan Seller shall correct or cure any such
defect within ninety (90) days from the date of notice from the Trustee of the
defect and if the Mortgage Loan Seller fails to correct or cure the defect
within such period, and such defect materially and adversely affects the
interests of the Certificateholders in the related Mortgage Loan, the Trustee
shall enforce the Mortgage Loan Seller's obligation pursuant to the Mortgage
Loan Purchase Agreement, within 90 days from the Trustee's notification, to
purchase such Mortgage Loan at the Repurchase Price; 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; provided,
however, that if such defect relates solely to the inability of the Mortgage
Loan Seller to deliver the original Security Instrument or intervening
assignments thereof, or a certified copy because the originals of such
documents, or a certified copy have not been returned by the applicable
jurisdiction, the Mortgage Loan Seller shall not be required to purchase such
Mortgage Loan if the Mortgage Loan Seller delivers such original documents or
certified copy promptly upon receipt, but in no event later than 360 days after
the Closing Date. The foregoing repurchase obligation shall not apply in the
event that the Mortgage Loan Seller cannot deliver such original or copy of any
document submitted for recording to the appropriate recording office in the
applicable jurisdiction because such document has not been returned by such
office; provided that the Mortgage Loan Seller shall instead deliver a recording
receipt of such recording office or, if such receipt is not available, a
certificate confirming that such documents have been accepted for recording, and
delivery to the Trustee shall be effected by the Mortgage Loan Seller within
thirty days of its receipt of the original recorded document.

     (b) No later than 180 days after the Closing Date, the Trustee will review,
for the benefit of the Certificateholders, the Mortgage Files delivered to it
and will execute and deliver or cause to be executed and delivered to the Seller
a Final Certification substantially in the form annexed as Exhibit H-3 to this
Agreement. In conducting such review, the Trustee will ascertain whether an
original of each document 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 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 or to
appear defective on its face, the Trustee shall promptly notify the Mortgage
Loan Seller and the Guarantor (provided, however, that with respect to those
documents described in subsection (b)(iv), (b)(v) and (b)(vi) of Section 2.01,
the Trustee's obligations shall extend only to the documents actually delivered
pursuant to such subsections). In accordance with the Mortgage Loan Purchase
Agreement, the Mortgage Loan Seller shall correct or cure any such defect or EMC
shall deliver to the Trustee and the Guarantor an Opinion of Counsel to the
effect that such defect does not materially or adversely affect the interests of
Certificateholders in such Mortgage Loan within 90 days from the date of notice
from the Trustee of the defect and if the Mortgage Loan Seller is unable to cure
such defect within such period, and if such defect materially and adversely
affects the interests of the Certificateholders in the related Mortgage Loan,
the Trustee shall enforce the Mortgage Loan Seller's obligation under the
Mortgage Loan Purchase Agreement to purchase such Mortgage Loan at the
Repurchase Price, provided, however, that if such defect relates solely to the
inability of the Mortgage Loan Seller to deliver the original Security
Instrument or intervening assignments thereof, or a certified copy, because the
originals of such documents. or a certified copy, have not been returned by the
applicable jurisdiction, the Mortgage Loan Seller shall not be required to
purchase such Mortgage Loan, if the Mortgage Loan Seller delivers such original
documents or certified copy promptly upon receipt, but in no event later than
360 days after the Closing Date.

     (c) In the event that a Mortgage Loan is purchased by the Mortgage Loan
Seller in accordance with Subsections 2.02(a) or (b) above, the Mortgage Loan
Seller shall remit to the Master Servicer the Repurchase Price for deposit in
the related Protected Account and the Mortgage Loan Seller shall provide to the
Trustee written notification detailing the components of the Repurchase Price.
Upon deposit of the Repurchase Price in the related Protected Account, the
Seller shall notify the Trustee and the Trustee (upon receipt of a Request for
Release in the form of Exhibit D attached hereto with respect to such Mortgage
Loan), shall release to the Mortgage Loan Seller the related Mortgage File and
the Trustee shall execute and deliver all instruments of transfer or assignment,
without recourse, furnished to it by the Mortgage Loan Seller as are necessary
to vest in the Mortgage Loan Seller title to and rights under the Mortgage Loan.
Such purchase shall be deemed to have occurred on the date on which the
Repurchase Price in available funds is received by the Trustee. The Trustee
shall amend the Mortgage Loan Schedule, which was previously delivered to it by
Seller in a form agreed to between the Seller and the Trustee, to reflect such
repurchase and shall promptly notify the Rating Agencies and the Master Servicer
of such amendment. The obligation of the Mortgage Loan Seller to repurchase any
Mortgage Loan as to which such a defect in a constituent document exists shall
be the sole remedy respecting such defect available to the Certificateholders or
to the Trustee on their behalf.

     Section 2.03 ASSIGNMENT OF INTEREST IN THE MORTGAGE LOAN PURCHASE
AGREEMENT. (a) The Seller hereby assigns to the Trustee, on behalf of the
Certificateholders, all of its right, title and interest in the Mortgage Loan
Purchase Agreement. The obligations of the Mortgage Loan Seller to substitute or
repurchase, as applicable, a Mortgage Loan shall be the Trustee's and the
Certificateholders' sole remedy for any breach thereof. At the request of the
Trustee, the Seller shall take such actions as may be necessary to enforce the
above right, title and interest on behalf of the Trustee and the
Certificateholders or shall execute such further documents as the Trustee may
reasonably require in order to enable the Trustee to carry out such enforcement.

     (b) If the Seller or the Trustee discovers a breach of any of the
representations and warranties set forth in the Mortgage Loan Purchase
Agreement, which breach materially and adversely affects the value of the
interests of Certificateholders or the Trustee in the related Mortgage Loan, the
party discovering the breach shall give prompt written notice of the breach to
the other parties. The Mortgage Loan Seller, within 90 days of its discovery or
receipt of notice that such breach has occurred (whichever occurs earlier),
shall cure the breach in all material respects or, subject to the Mortgage Loan
Purchase Agreement or Section 2.04 of this Agreement, as applicable, shall
purchase the Mortgage Loan or any property acquired with respect thereto from
the Trustee; provided, however, that if there is a breach of any representation
set forth in the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable, and the Mortgage Loan or the related property acquired
with respect thereto has been sold, then the Mortgage Loan Seller shall pay, in
lieu of the Repurchase Price, any excess of the Repurchase Price over the Net
Liquidation Proceeds received upon such sale. (If the Net Liquidation Proceeds
exceed the Repurchase Price, any excess shall be paid to the Mortgage Loan
Seller to the extent not required by law to be paid to the borrower.) Any such
purchase by the Mortgage Loan Seller shall be made by providing an amount equal
to the Repurchase Price to the Master Servicer for deposit in the related
Protected Account and written notification detailing the components of such
Repurchase Price. The Seller shall notify the Trustee and submit to the Trustee
a Request for Release in the form of Exhibit D attached hereto, and the Trustee
shall release to the Mortgage Loan Seller the related Mortgage File and the
Trustee shall execute and deliver all instruments of transfer or assignment
furnished to it by the Mortgage Loan Seller, without recourse, as are necessary
to vest in the Mortgage Loan Seller title to and rights under the Mortgage Loan
or any property acquired with respect thereto. Such purchase shall be deemed to
have occurred on the date on which the Repurchase Price in available funds is
received by the Trustee. The Trustee shall amend the Mortgage Loan Schedule to
reflect such repurchase and shall promptly notify the Master Servicer and the
Rating Agencies of such amendment. Enforcement of the obligation of the Mortgage
Loan Seller to purchase (or substitute a Substitute Mortgage Loan for) any
Mortgage Loan or any property acquired with respect thereto (or pay the
Repurchase Price as set forth in the above proviso) as to which a breach has
occurred and is continuing shall constitute the sole remedy respecting such
breach available to the Certificateholders or the Trustee on their behalf.

     Section 2.04 SUBSTITUTION OF MORTGAGE LOANS. Notwithstanding anything to
the contrary in this Agreement, in lieu of purchasing a Mortgage Loan pursuant
to the Mortgage Loan Purchase Agreement or Sections 2.02 or 2.03 of this
Agreement, the Mortgage Loan Seller may, no later than the date by which such
purchase by the Mortgage Loan Seller would otherwise be required, tender to the
Trustee a Substitute Mortgage Loan accompanied by a certificate of an authorized
officer of the Mortgage Loan Seller that such Substitute Mortgage Loan conforms
to the requirements set forth in the definition of "Substitute Mortgage Loan" in
the Mortgage Loan Purchase Agreement or this Agreement, as applicable; provided,
however, that substitution pursuant to the Mortgage Loan Purchase Agreement or
Section 2.04 of this Agreement, as applicable, in lieu of purchase shall not be
permitted after the termination of the two-year period beginning on the Startup
Day; provided, further, that if the breach 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 substitution must occur within 90 days from the date the breach
was discovered. The Trustee shall examine the Mortgage File for any Substitute
Mortgage Loan in the manner set forth in Section 2.02(a) and the Trustee shall
notify the Mortgage Loan Seller, in writing, within five Business Days after
receipt, whether or not the documents relating to the Substitute Mortgage Loan
satisfy the requirements of the fourth sentence of Subsection 2.02(a). Within
two Business Days after such notification, the Mortgage Loan Seller shall
provide to the Trustee for deposit in the Distribution Account the amount, if
any, by which the Outstanding Principal Balance as of the next preceding Due
Date of the Mortgage Loan for which substitution is being made, after giving
effect to Scheduled Principal due on such date, exceeds the Outstanding
Principal Balance as of such date of the Substitute Mortgage Loan, after giving
effect to Scheduled Principal due on such date, which amount shall be treated
for the purposes of this Agreement as if it were the payment by the Mortgage
Loan Seller of the Repurchase Price for the purchase of a Mortgage Loan by the
Mortgage Loan Seller. After such notification to the Mortgage Loan Seller and,
if any such excess exists, upon receipt of such deposit, the Trustee shall
accept such Substitute Mortgage Loan which shall thereafter be deemed to be a
Mortgage Loan hereunder. In the event of such a substitution, accrued interest
on the Substitute Mortgage Loan for the month in which the substitution occurs
and any Principal Prepayments made thereon during such month shall be the
property of the Trust Fund and accrued interest for such month on the Mortgage
Loan for which the substitution is made and any Principal Prepayments made
thereon during such month shall be the property of the Mortgage Loan Seller. The
Scheduled Principal on a Substitute Mortgage Loan due on the Due Date in the
month of substitution shall be the property of the Mortgage Loan Seller and the
Scheduled Principal on the Mortgage Loan for which the substitution is made due
on such Due Date shall be the property of the Trust Fund. Upon acceptance of the
Substitute Mortgage Loan (and delivery to the Trustee a Request for Release for
such Mortgage Loan), the Trustee shall release to the Mortgage Loan Seller the
related Mortgage File related to any Mortgage Loan released pursuant to the
Mortgage Loan Purchase Agreement or Section 2.04 of this Agreement, as
applicable, and shall execute and deliver all instruments of transfer or
assignment, without recourse, in form as provided to it as are necessary to vest
in the Mortgage Loan Seller title to and rights under any Mortgage Loan released
pursuant to the Mortgage Loan Purchase Agreement or Section 2.04 of this
Agreement, as applicable. The Mortgage Loan Seller shall deliver the documents
related to the Substitute Mortgage Loan in accordance with the provisions of the
Mortgage Loan Purchase Agreement or Subsections 2.01(b) and 2.02(b) of this
Agreement, as applicable, with the date of acceptance of the Substitute Mortgage
Loan deemed to be the Closing Date for purposes of the time periods set forth in
those Subsections. The representations and warranties set forth in the Mortgage
Loan Purchase Agreement shall be deemed to have been made by the Mortgage Loan
Seller with

                                      -37-

<PAGE>

respect to each Substitute Mortgage Loan as of the date of acceptance of such
Mortgage Loan by the Trustee. The Master Servicer shall amend the Mortgage Loan
Schedule to reflect such substitution and shall provide a copy of such amended
Mortgage Loan Schedule to the Trustee and the Rating Agencies.

     Section 2.05 ISSUANCE OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the other assets comprising the Trust
Fund and, concurrently therewith, has signed, and countersigned and delivered to
the Seller, in exchange therefor, Certificates in such authorized denominations
representing such Fractional Undivided Interests as the Seller has requested.
The Trustee agrees that it will hold the Mortgage Loans and such other assets as
may from time to time be delivered to it segregated on the books of the Trustee
in trust for the benefit of the Certificateholders.

     The Seller, concurrently with the execution and delivery hereof, does
hereby transfer, assign, set over and otherwise convey in trust to the Trustee
without recourse all the right, title and interest of the Seller in and to the
REMIC IA Regular Interests and REMIC IB Regular Interests and the other assets
of REMIC II for the benefit of the holders of the REMIC II REMIC Interests. The
Trustee acknowledges receipt of the REMIC IA Regular Interests and REMIC IB
Regular Interests (which are uncertificated) and the other assets of REMIC II
and declares that it holds and will hold the same in trust for the exclusive use
and benefit of the holders of the REMIC II REMIC Interests.

     The Seller, concurrently with the execution and delivery hereof, does
hereby transfer, assign, set over and otherwise convey in trust to the Trustee
without recourse all the right, title and interest of the Seller in and to the
REMIC II Regular Interests and the other assets of REMIC II for the benefit of
the holders of the REMIC III Certificates. The Trustee acknowledges receipt of
the REMIC II Regular Interests (which are uncertificated) and the other assets
of REMIC II and declares that it holds and will hold the same in trust for the
exclusive use and benefit of the holders of the REMIC III Certificates.

     Section 2.06 REPRESENTATIONS AND WARRANTIES CONCERNING THE SELLER. The
Seller hereby represents and warrants to the Trustee, the Guarantor and the
Master Servicer as follows:

          (i) the Seller (a) is a corporation duly organized, validly existing
     and in good standing under the laws of the State of Delaware and (b) is
     qualified and in good standing as a foreign corporation to do business in
     each jurisdiction where such qualification is necessary, except where the
     failure so to qualify would not reasonably be expected to have a material
     adverse effect on the Seller's business as presently conducted or on the
     Purchaser's ability to enter into this Agreement and to consummate the
     transactions contemplated hereby;

          (ii) the Seller has full corporate power to own its property, to carry
     on its business as presently conducted and to enter into and perform its
     obligations under this Agreement;

          (iii) the execution and delivery by the Seller of this Agreement have
     been duly authorized by all necessary corporate action on the part of the
     Seller; and neither the execution and delivery of this Agreement, nor the
     consummation of the transactions herein

                                      -38-

<PAGE>

     contemplated, nor compliance with the provisions hereof, will conflict with
     or result in a breach of, or constitute a default under, any of the
     provisions of any law, governmental rule, regulation, judgment, decree or
     order binding on the Seller or its properties or the articles of
     incorporation or by-laws of the Seller, except those conflicts, breaches or
     defaults which would not reasonably be expected to have a material adverse
     effect on the Seller's ability to enter into this Agreement and to
     consummate the transactions contemplated hereby;

          (iv) the execution, delivery and performance by the Seller of this
     Agreement and the consummation of the transactions contemplated hereby do
     not require the consent or approval of, the giving of notice to, the
     registration with, or the taking of any other action in respect of, any
     state, federal or other governmental authority or agency, except those
     consents, approvals, notices, registrations or other actions as have
     already been obtained, given or made;

          (v) this Agreement has been duly executed and delivered by the Seller
     and, assuming due authorization, execution and delivery by the other
     parties hereto, constitutes a valid and binding obligation of the Seller
     enforceable against it in accordance with its terms (subject to applicable
     bankruptcy and insolvency laws and other similar laws affecting the
     enforcement of the rights of creditors generally);

          (vi) there are no actions, suits or proceedings pending or, to the
     knowledge of the Seller, threatened against the Seller, before or by any
     court, administrative agency, arbitrator or governmental body (i) with
     respect to any of the transactions contemplated by this Agreement or (ii)
     with respect to any other matter which in the judgment of the Seller will
     be determined adversely to the Seller and will if determined adversely to
     the Seller materially and adversely affect the Seller's ability to enter
     into this Agreement or perform its obligations under this Agreement; and
     the Seller is not in default with respect to any order of any court,
     administrative agency, arbitrator or governmental body so as to materially
     and adversely affect the transactions contemplated by this Agreement; and

          (vii) immediately prior to the transfer and assignment to the Trustee,
     each Mortgage Note and each Mortgage were not subject to an assignment or
     pledge, and the Seller had good and marketable title to and was the sole

     charge, claim or security interest.

                                   ARTICLE III

                         Servicing of the Mortgage Loans

     Section 3.01 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS. For and on
behalf of the Certificateholders, the Master Servicer shall service and
administer the Mortgage Loans in accordance with customary and usual standards
of practice of prudent mortgage loan servicers in the respective states in which
the Mortgaged Properties are located. In connection with such servicing and
administration, the Master Servicer shall have full power and authority, acting
alone and/or through subservicers as provided in Section 3.03, to do or cause to
be done any and all things that it may deem necessary or desirable in connection
with such servicing and administration, including but not limited to, the power
and authority, subject to the terms hereof (i) to execute and deliver, on behalf
of the Certificateholders and the Trustee, customary consents or waivers and
other instruments and documents, (ii) to consent to transfers of any Mortgaged
Property and assumptions of the Mortgage Notes and related Mortgages (but only
in the manner provided herein), (iii) to collect any Insurance Proceeds and
other Liquidation Proceeds, and (iv) subject to Section 3.13, to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan; provided that the Master Servicer shall take no
action that is inconsistent with or prejudices the interests of the Trust Fund
or the Certificateholders in any Mortgage Loan or the rights and interests of
the Seller and the Trustee under this Agreement. The Master Servicer shall also
follow any applicable bankruptcy court, HUD, FHA or VA requirements and/or
regulations, where applicable, regarding the servicing of the Mortgage Loans,
including but not limited to any limitations on the ability to institute
foreclosure proceedings upon the occurrence of a default in the payment of
Monthly Payments, or the making of insurance or guaranty claims.

          Without limiting the generality of the foregoing, the Master Servicer,
in its own name or in the name of the Trust, the Seller or the Trustee, is
hereby authorized and empowered by the Trust, the Seller and the Trustee, when
the Master Servicer believes it appropriate in its reasonable judgment, to
execute and deliver, on behalf of the Trustee, the Seller, the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge and all other
comparable instruments, with respect to the Mortgage Loans, and with respect to
the Mortgaged Properties held for the benefit of the Certificateholders. The
Master Servicer shall prepare and deliver to the Seller and/or the Trustee such
documents requiring execution and delivery by any or all of them as are
necessary or appropriate to enable the Master Servicer to service and administer
the Mortgage Loans. Upon receipt of such documents, the Seller and/or the
Trustee shall execute such documents and deliver them to the Master Servicer.

          In accordance with the standards of the first paragraph of this
Section 3.01, the Master Servicer shall advance or cause to be advanced funds as
necessary for the purpose of effecting the payment of taxes and assessments on
the Mortgaged Properties, which advances shall be reimbursable in the first
instance from related collections from the Mortgagors pursuant to Section 4.03,
and further as provided in Section 4.02. All costs incurred by the Master
Servicer, if any, in effecting the timely payments of taxes and assessments on
the Mortgaged Properties and related insurance premiums shall not, for the
purpose of calculating monthly distributions to the Certificateholders, be added
to the Stated Principal Balance under the related Mortgage Loans,
notwithstanding that the terms of such Mortgage Loans so permit.

          Section 3.02 REMIC-RELATED COVENANTS.

          For as long as each REMIC shall exist, the Trustee shall act in
accordance herewith to assure continuing treatment of such REMIC as a REMIC, and
the Trustee shall comply with any directions of the Seller, any subservicer or
the Master Servicer to assure such continuing treatment. In particular, the
Trustee shall not (a) sell or permit the sale of all or any portion of the
Mortgage Loans or of any investment of deposits in an Account unless such sale
is as a result of a repurchase of the Mortgage Loans pursuant to this Agreement
or the Trustee has received a REMIC Opinion prepared at the expense of the Trust
Fund; and (b) other than with respect to a substitution pursuant to Section 2.04
of this Agreement, as applicable, accept any contribution to any REMIC after the
Startup Day without receipt of a REMIC Opinion.

          For as long as each REMIC shall exist, the Master Servicer shall act
in accordance herewith to assure continuing treatment of such REMIC as a REMIC.
Notwithstanding anything in this Agreement to the contrary, the Master Servicer
shall not (unless the Mortgagor is in default with respect to the Mortgage Loan
or such default is, in the judgment of the Master Servicer, reasonably
foreseeable) (i) make or permit any modification with respect to any Mortgage
Loan that would change the Mortgage Rate, reduce or increase the principal
balance (except for reductions resulting from actual payments of principal) or
change the final maturity date on such Mortgage Loan (other than, with respect
to FHA Loans or VA Loans, as may be required by the FHA, HUD or the VA, as
applicable, in connection with servicing regulations for such Mortgage Loans) or
(ii) make or permit any modification, waiver or amendment of any term of any
Mortgage Loan that would both (a) effect an exchange or reissuance of such
Mortgage Loan under Section 1001 of the Code (or Treasury regulations
promulgated thereunder) and (b) cause any of any REMIC to fail to qualify as a
REMIC under the Code or the imposition of any tax on "prohibited transactions"
or "contributions" after the startup date under the REMIC Provisions.

     Section 3.03 SUBSERVICING; MONITORING OF SUBSERVICERS; ENFORCEMENT OF
                  OBLIGATIONS.

          (a) The Master Servicer may arrange for the subservicing of any
Mortgage Loan by a subservicer pursuant to a Subservicing Agreement; provided
that such subservicing arrangement and the terms of the related Subservicing
Agreement must provide for the servicing of such Mortgage Loans in a manner
consistent with the servicing arrangements contemplated hereunder and be
acceptable to the Guarantor. Each Rating Agency shall be notified of any
subservicing arrangement. Notwithstanding the provisions of any Subservicing
Agreement, any of the provisions herein relating to agreements or arrangements
between the Master Servicer or a subservicer or reference to actions taken
through the Master Servicer or otherwise, the Master Servicer shall remain
obligated and liable to the Seller, the Trust, the Trustee and the
Certificateholders for the servicing and administration of the Mortgage Loans in
accordance with the provisions of this Agreement without diminution of such
obligation or liability by virtue of any such Subservicing Agreements or
arrangements or by virtue of indemnification from the subservicer and to the
same extent and under the same terms and conditions as if the Master Servicer
alone were servicing and administering the Mortgage Loans. Every Subservicing
Agreement entered into by the Master Servicer shall contain a provision giving
the successor Master Servicer the option to terminate such agreement in the
event a successor Master Servicer is appointed. All actions of each subservicer
performed pursuant to the

                                      -41-

<PAGE>

related Subservicing Agreement shall be performed as an agent of the Master
Servicer with the same force and effect as if performed directly by the Master
Servicer.

          (b) For purposes of this Agreement, the Master Servicer shall be
deemed to have received any collections, recoveries or payments with respect to
the Mortgage Loans that are received by a subservicer regardless of whether such
payments are remitted by the subservicer to the Master Servicer.

          (c) The Master Servicer, on behalf of the Trustee and the
Certificateholders, shall enforce the obligations of each subservicer under the
related Subservicing Agreement, and shall, in the event that any such
subservicer fails to perform its obligations in accordance with the related
Subservicing Agreement, subject to the preceding paragraph, terminate the rights
and obligations of such subservicer thereunder and thereafter perform the
primary servicing obligations with respect to such Mortgage Loans; provided,
however, it is understood and acknowledged by the parties hereto that there will
be a period of transition (not to exceed 90 days) before the actual servicing
functions can be fully transferred to the Master Servicer. Such enforcement,
including, without limitation, the legal prosecution of claims, termination of
Subservicing Agreements and the pursuit of other appropriate remedies, shall be
in such form and carried out to such an extent and at such time as the Master
Servicer, in its good faith business judgment, would require were it the owner
of the related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement at its own expense, provided that the Master Servicer shall not be
required to prosecute or defend any legal action except to the extent that the
Master Servicer shall have received reasonable indemnity for its costs and
expenses in pursuing such action.

     Section 3.04 SUCCESSOR MASTER SERVICER AND SUBSERVICING AGREEMENTS.

          In the event that, pursuant to Section 8.01 hereof, the Trustee or any
other Person shall become Successor Master Servicer, such Successor Master
Servicer may, at its option, succeed to any rights and obligations of the
predecessor Master Servicer under any Subservicing Agreement in accordance with
the terms thereof; provided that such Successor Master Servicer shall not incur
any liability or have any obligations in its capacity as servicer under a
Subservicing Agreement arising prior to the date of such succession unless it
expressly elects to succeed to the rights and obligations of the predecessor
Master Servicer thereunder; and the predecessor Master Servicer shall not
thereby be relieved of any liability or obligations under the Subservicing
Agreement arising prior to the date of such succession. Notwithstanding the
foregoing, the parties hereto agree that the Trustee, in its capacity as
Successor Master Servicer, immediately will assume all of the obligations of the
Master Servicer to make Monthly Advances and the Trustee will assume the other
duties of the Master Servicer as soon as practicable, but in no event later than
90 days after the Trustee becomes Successor Master Servicer pursuant to the
preceding sentence. Notwithstanding the foregoing, the Trustee, in its capacity
as Successor Master Servicer, shall not be responsible for the lack of
information and/or documents that it cannot obtain through reasonable efforts.

          Such predecessor Master Servicer shall, upon request of the Trustee,
but at the expense of such predecessor Master Servicer, deliver to the assuming
party all documents and records relating to each Subservicing Agreement and the
Mortgage Loans then being serviced

                                      -42-

<PAGE>

thereunder and an accounting of amounts collected held by it and otherwise use
its best efforts to effect the orderly and efficient transfer of the
Subservicing Agreement to the assuming party.

     Section 3.05 RIGHTS OF THE SELLER AND THE TRUSTEE IN RESPECT OF THE MASTER
                  SERVICER.

          Neither the Trustee nor the Seller shall have any responsibility or
liability for any action or failure to act by the Master Servicer and none of
them is obligated to supervise the performance of the Master Servicer.

     Section 3.06 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS.

          (a) Except as otherwise provided in this Section 3.06, when any
property subject to a Mortgage has been or is about to be conveyed by the
Mortgagor, the Master Servicer shall to the extent that it has knowledge of such
conveyance, enforce any due-on-sale clause contained in any Mortgage Note or
Mortgage, to the extent permitted under applicable law and governmental
regulations, but only to the extent that such enforcement will not adversely
affect or jeopardize coverage under any Required Insurance Policy.
Notwithstanding the foregoing, the Master Servicer is not required to exercise
such rights with respect to a Mortgage Loan if the Person to whom the related
Mortgaged Property has been conveyed or is proposed to be conveyed satisfies the
terms and conditions contained in the Mortgage Note and Mortgage related thereto
and the consent of the mortgagee under such Mortgage Note or Mortgage is not
otherwise so required under such Mortgage Note or Mortgage as a condition to
such transfer. In the event that the Master Servicer is prohibited by law from
enforcing any such due-on-sale clause, or if coverage under any Required
Insurance Policy would be adversely affected, or if nonenforcement is otherwise
permitted hereunder, the Master Servicer is authorized, subject to Section
3.06(b), to take or enter into an assumption and modification agreement from or
with the person to whom such property has been or is about to be conveyed,
pursuant to which such person becomes liable under the Mortgage Note and, unless
prohibited by applicable state law, the Mortgagor remains liable thereon,
provided that the Mortgage Loan shall continue to be covered (if so covered
before the Master Servicer enters such agreement) by the applicable Required
Insurance Policies, FHA insurance or VA guaranty. The Master Servicer, subject
to Section 3.06(b), is also authorized with the prior approval of the insurers
under any Required Insurance Policies to enter into a substitution of liability
agreement with such Person, pursuant to which the original Mortgagor is released
from liability and such Person is substituted as Mortgagor and becomes liable
under the Mortgage Note. Notwithstanding the foregoing, the Master Servicer
shall not be deemed to be in default under this Section 3.06(a) by reason of any
transfer or assumption that the Master Servicer reasonably believes it is
restricted by law from preventing.

          (b) Subject to the Master Servicer's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.06(a), in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, and such Person
is to enter into an assumption agreement or modification agreement or supplement
to the Mortgage Note or Mortgage that requires the signature of the Trustee, or
if an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Master Servicer shall prepare
and deliver or cause to be prepared and delivered to the Trustee for signature
and shall direct, in writing, the Trustee to execute the assumption agreement
with the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as

                                      -43-

<PAGE>

are reasonable or necessary to carry out the terms of the Mortgage Note or
Mortgage or otherwise to comply with any applicable laws regarding assumptions
or the transfer of the Mortgaged Property to such Person. In connection with any
such assumption, no material term of the Mortgage Note (including, but not
limited to, the Mortgage Rate, the amount of the Scheduled Payment and any other
term affecting the amount or timing of payment on the Mortgage Loan) may be
changed. In addition, the substitute Mortgagor and the Mortgaged Property must
be acceptable to the Master Servicer in accordance with its servicing standards
as then in effect. The Master Servicer shall notify the Trustee that any such
substitution or assumption agreement has been completed by forwarding to the
Trustee the original of such substitution or assumption agreement, which in the
case of the original shall be added to the related Mortgage File and shall, for
all purposes, be considered a part of such Mortgage File to the same extent as
all other documents and instruments constituting a part thereof. Any fee
collected by the Master Servicer for entering into an assumption or substitution
of liability agreement will be retained by the Master Servicer as additional
servicing compensation. If the aggregate Current Principal Amount of the Class
B-3 Certificates has been reduced to zero, the Master Servicer shall not take or
enter into any substitution, assumption or modification agreement without
obtaining the prior written consent of the Guarantor to such substitution,
assumption or modification agreement. The Master Servicer shall submit to the
Guarantor with its request for consent, such information related to the proposed
substitution, assumption or modification agreement as can be expected to be
needed by the Guarantor to evaluate the Master Servicer's request, including the
terms of the proposed substitution, assumption or modification and the reasons
for the Master Servicer's decision that such substitution, assumption or
modification agreement should be taken or entered into with respect to such
Group 1 or Group 2 Mortgage Loan. The Guarantor shall be deemed to have
consented to the Master Servicer's request in the event that the Guarantor does
not either provide the Master Servicer with its written consent to such
requested substitution, assumption or modification agreement or written notice
of its objection to such substitution, assumption or modification agreement
within five Business Days of its receipt of the Master Servicer's request. Such
requests shall be sent to the Guarantor at: Fannie Mae, 3900 Wisconsin Avenue,
N.W., Washington, D.C. 20016, Attn: Vice President-Loss Mitigation. With respect
to each substitution, assumption or modification agreement which is entered into
after the Current Principal Amount of the Class B-3 Certificates has been
reduced to zero, the Master Servicer shall give written notice to the Guarantor
to the following address: Fannie Mae, 4000 Wisconsin Avenue, N.W., Washington,
D.C. 20016, Attn: Bond Administration. Such notice shall be delivered within
thirty Business Days following the date of such substitution, assumption or
modification agreement.

     Section 3.07 RELEASE OF MORTGAGE FILES.

          (a) Upon the payment in full of any Mortgage Loan or the escrow of
such amount in a manner customary for such purposes for payment to
Certificateholders on the next Distribution Date, the Master Servicer will
promptly furnish to the Trustee two copies of a certification substantially in
the form of Exhibit D hereto signed by a Servicing Officer or in a mutually
agreeable electronic format which will, in lieu of a signature on its face,
originate from a Servicing Officer (which certification shall include a
statement to the effect that all amounts received in connection with such
payment that are required to be deposited in the Protected Account maintained by
the Master Servicer have been or will be so deposited or escrowed) and shall
request that the Trustee deliver to the Master Servicer the related Mortgage
File. Upon receipt of such certification and

                                      -44-

<PAGE>

request, the Trustee shall promptly release the related Mortgage File to the
Master Servicer and the Trustee shall have any further responsibility with
regard to such Mortgage File. Upon any such payment in full, the Master Servicer
is authorized to give, as agent for the Trustee, as the mortgagee under the
Mortgage that secured the Mortgage Loan, an instrument of satisfaction (or
assignment of mortgage without recourse) regarding the Mortgaged Property
subject to the Mortgage, which instrument of satisfaction or assignment, as the
case may be, shall be delivered to the Person or Persons entitled thereto
against receipt therefor of such payment, it being understood and agreed that no
expenses incurred in connection with such instrument of satisfaction or
assignment, as the case may be, shall be chargeable to the Protected Account.

          (b) From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan, the Trustee shall execute such documents as
shall be prepared and furnished to the Trustee by the Master Servicer (in form
reasonably acceptable to the Trustee) and as are necessary to the prosecution of
any such proceedings. The Trustee shall, upon the request of the Master
Servicer, and delivery to the Trustee, of two copies of a request for release
signed by a Servicing Officer substantially in the form of Exhibit D (or in a
mutually agreeable electronic format which will, in lieu of a signature on its
face, originate from a Servicing Officer), release the related Mortgage File
held in its possession or control to the Master Servicer. Such trust receipt
shall obligate the Master Servicer to return the Mortgage File to the Trustee,
when the need therefor by the Master Servicer no longer exists unless the
Mortgage Loan shall be liquidated, in which case, upon receipt of a certificate
of a Servicing Officer similar to that hereinabove specified, the Mortgage File
shall be released by the Trustee, to the Master Servicer.

          (c) The Trustee shall execute and deliver to the Master Servicer any
court pleadings, requests for trustee's sale or other documents furnished to the
Trustee necessary or advisable to (i) the foreclosure or trustee's sale with
respect to a Mortgaged Property; (ii) any legal action brought to obtain
judgment against any Mortgagor on the Mortgage Note or Security Instrument;
(iii) obtain a deficiency judgment against the Mortgagor; or (iv) enforce any
other rights or remedies provided by the Mortgage Note or Security Instrument or
otherwise available at law or equity. Together with such documents or pleadings
the Master Servicer shall deliver to the Trustee a certificate of a Servicing
Officer in which it requests the Trustee to execute the pleadings or documents.
The certificate shall certify and explain the reasons for which the pleadings or
documents are required. It shall further certify that the Trustee's execution
and delivery of the pleadings or documents will not invalidate any insurance
coverage under the Required Insurance Policies or invalidate or otherwise affect
the lien of the Security Instrument, except for the termination of such a lien
upon completion of the foreclosure or trustee's sale.

     Section 3.08 DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF MASTER SERVICER
                  TO BE HELD FOR TRUSTEE.

          Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Trustee as required by this Agreement all
documents and instruments in respect of a Mortgage Loan coming into the
possession of the Master Servicer from time to time and shall account fully to
the Trustee for any funds received by the Master Servicer or that otherwise are
collected by the Master Servicer as Liquidation Proceeds or Insurance Proceeds
in respect of any Mortgage Loan. All Mortgage Files and funds collected or held
by, or under the control of, the

                                      -45-

<PAGE>

Master Servicer in respect of any Mortgage Loans, whether from the collection of
principal and interest payments or from Liquidation Proceeds, including but not
limited to, any funds on deposit in the Protected Account, shall be held by the
Master Servicer for and on behalf of the Trustee and shall be and remain the
sole and exclusive property of the Trustee, subject to the applicable provisions
of this Agreement. The Master Servicer also agrees that it shall not create,
incur or subject any Mortgage File or any funds that are deposited in the
Protected Account or Distribution Account or in any Escrow Account, or any funds
that otherwise are or may become due or payable to the Trustee for the benefit
of the Certificateholders, to any claim, lien, security interest, judgment,
levy, writ of attachment or other encumbrance, or assert by legal action or
otherwise any claim or right of set off against any Mortgage File or any funds
collected on, or in connection with, a Mortgage Loan, except, however, that the
Master Servicer shall be entitled to set off against and deduct from any such
funds any amounts that are properly due and payable to the Master Servicer under
this Agreement.

     Section 3.09 MAINTENANCE OF HAZARD INSURANCE.

          The Master Servicer shall cause to be maintained, for each Mortgage
Loan, hazard insurance on buildings upon, or comprising part of, the Mortgaged
Property against loss by fire, hazards of extended coverage and such other
hazards as are customary in the area where the Mortgaged Property is located
with an insurer which is licensed to do business in the state where the
Mortgaged Property is located. Each such policy of standard hazard insurance
shall contain, or have an accompanying endorsement that contains, a standard
mortgagee clause. The Master Servicer shall also cause flood insurance to be
maintained on property acquired upon foreclosure or deed in lieu of foreclosure
of any Mortgage Loan, to the extent described below. Pursuant to Section 4.01,
any amounts collected by the Master Servicer under any such policies (other than
the amounts to be applied to the restoration or repair of the related Mortgaged
Property or property thus acquired or amounts released to the Mortgagor in
accordance with the Master Servicer's normal servicing procedures) shall be
deposited in the Protected Account maintained by the Master Servicer. Any cost
incurred by the Master Servicer in maintaining any such insurance shall not, for
the purpose of calculating monthly distributions to the Certificateholders or
remittances to the Trustee for their benefit, be added to the principal balance
of the Mortgage Loan, notwithstanding that the terms of the Mortgage Loan so
permit. Such costs shall be recoverable by the Master Servicer out of late
payments by the related Mortgagor or out of Liquidation Proceeds to the extent
permitted by Section 4.02. It is understood and agreed that no earthquake or
other additional insurance is to be required of any Mortgagor or maintained on
property acquired in respect of a Mortgage other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance. If the Mortgaged Property is located at the
time of origination of the Mortgage Loan in a federally designated special flood
hazard area and such area is participating in the national flood insurance
program, the Master Servicer shall cause flood insurance to be maintained with
respect to such Mortgage Loan. Such flood insurance shall be in an amount equal
to the least of (I) the Stated Principal Balance of the related Mortgage Loan,
(ii) minimum amount required to compensate for damage or loss on a replacement
cost basis or (iii) the maximum amount of such insurance available for the
related Mortgaged Property under the Flood Disaster Protection Act of 1973, as
amended.

                                      -46-

<PAGE>

          In the event that the Master Servicer shall obtain and maintain a
blanket policy insuring against hazard losses on all of the Mortgage Loans, it
shall conclusively be deemed to have satisfied its obligations as set forth in
the first sentence of this Section 3.09, it being understood and agreed that
such policy may contain a deductible clause on terms substantially equivalent to
those commercially available and maintained by comparable servicers. If such
policy contains a deductible clause, the Master Servicer shall, in the event
that there shall not have been maintained on the related Mortgaged Property a
policy complying with the first sentence of this Section 3.09, and there shall
have been a loss that would have been covered by such policy, deposit in the
Protected Account maintained by the Master Servicer the amount not otherwise
payable under the blanket policy because of such deductible clause. Such deposit
shall constitute a Servicing Advance. In connection with its activities as
administrator and servicer of the Mortgage Loans, the Master Servicer agrees to
present, on behalf of itself, the Seller and the Trustee for the benefit of the
Certificateholders, claims under any such blanket policy.

     Section 3.10 PRESENTMENT OF CLAIMS AND COLLECTION OF PROCEEDS.

          The Master Servicer shall prepare and present on behalf of the Trustee
and the Certificateholders all claims under the Insurance Policies and take such
actions (including the negotiation, settlement, compromise or enforcement of the
insured's claim) as shall be necessary to realize recovery under such Insurance
Policies. Any proceeds disbursed to the Master Servicer in respect of such
Insurance Policies shall be promptly deposited in the Protected Account
maintained by the Master Servicer upon receipt, except that any amounts realized
that are to be applied to the repair or restoration of the related Mortgaged
Property as a condition precedent to the presentation of claims on the related
Mortgage Loan to the insurer under any applicable Insurance Policy need not be
so deposited (or remitted).

     Section 3.11 [RESERVED].

     Section 3.12 TRUSTEE TO RETAIN POSSESSION OF CERTAIN INSURANCE POLICIES
                  AND DOCUMENTS.

          The Trustee shall retain possession and custody of the originals (to
the extent available) of any Primary Mortgage Insurance Policies, or certificate
of insurance if applicable, and any certificates of renewal as to the foregoing
as may be issued from time to time. Until all amounts distributable in respect
of the Certificates have been distributed in full and the Master Servicer
otherwise has fulfilled its obligations under this Agreement, the Trustee shall
also retain possession and custody of each Mortgage File in accordance with and
subject to the terms and conditions of this Agreement. The Master Servicer shall
promptly deliver or cause to be delivered to the Trustee, upon the execution or
receipt thereof the originals of any Primary Mortgage Insurance Policies, any
certificates of renewal, and such other documents or instruments that constitute
portions of the Mortgage File that come into the possession of the Master
Servicer from time to time.

     Section 3.13 REALIZATION UPON DEFAULTED MORTGAGE LOANS; DETERMINATION OF
                  EXCESS LIQUIDATION PROCEEDS AND REALIZED LOSSES; REPURCHASES
                  OF CERTAIN MORTGAGE LOANS.

                                      -47-

          (a) The Master Servicer shall use reasonable efforts to foreclose upon
or otherwise comparably convert the ownership of properties securing such of the
Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments. In
connection with such foreclosure or other conversion, the Master Servicer shall
follow such practices and procedures as it shall deem necessary or advisable and
as shall be normal and usual in its general mortgage servicing activities and
the requirements of the insurer under any Required Insurance Policy; provided
that the Master Servicer shall not be required to expend its own funds in
connection with any foreclosure or towards the restoration of any property
unless it shall determine (i) that such restoration and/or foreclosure will
increase the proceeds of liquidation of the Mortgage Loan after reimbursement to
itself of such expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Protected Account maintained by the Master
Servicer pursuant to Section 4.02). If the Master Servicer reasonably believes
that Liquidation Proceeds with respect to any such Mortgage Loan would not be
increased as a result of such foreclosure or other action, such Mortgage Loan
will be charged-off and will become a Liquidated Loan. The Master Servicer will
give notice of any such charge-off to the Trustee. The Master Servicer shall be
responsible for all other costs and expenses incurred by it in any such
proceedings; provided that such costs and expenses shall be Servicing Advances
and that it shall be entitled to reimbursement thereof from the proceeds of
liquidation of the related Mortgaged Property, as contemplated in Section 4.02.
If the Master Servicer has knowledge that a Mortgaged Property that the Master
Servicer is contemplating acquiring in foreclosure or by deed- in-lieu of
foreclosure is located within a one-mile radius of any site with environmental
or hazardous waste risks known to the Master Servicer, the Master Servicer will,
prior to acquiring the Mortgaged Property, consider such risks and only take
action in accordance with its established environmental review procedures.
Notwithstanding the foregoing, with respect to the Group 1 or Group 2 Mortgage
Loans, if such environmental audit reveals, or if the Master Servicer has
knowledge or notice, that the Mortgaged Property securing such Group 1 or Group
2 Mortgage Loan contains such wastes or substances or is within one mile of the
site of such wastes or substances, the Master Servicer shall not foreclose or
accept a deed in lieu of foreclosure without the prior written consent of the
Guarantor.

          With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders (or the Trustee's nominee on behalf of the
Certificateholders). The Trustee's name shall be placed on the title to such REO
Property solely as the Trustee hereunder and not in its individual capacity. The
Master Servicer shall ensure that the title to such REO Property references this
Agreement and the Trustee's capacity hereunder. Pursuant to its efforts to sell
such REO Property, the Master Servicer shall either itself or through an agent
selected by the Master Servicer protect and conserve such REO Property in the
same manner and to such extent as is customary in the locality where such REO
Property is located and may, incident to its conservation and protection of the
interests of the Certificateholders, rent the same, or any part thereof, as the
Master Servicer deems to be in the best interest of the Master Servicer and the
Certificateholders for the period prior to the sale of such REO Property. The
Master Servicer shall prepare for and deliver to the Trustee a statement with
respect to each REO Property that has been rented showing the aggregate rental
income received and all expenses incurred in connection with the management and
maintenance of such REO Property at such times as is necessary to enable the
Trustee to comply with the reporting requirements of the REMIC Provisions. The
net monthly rental income, if any, from such REO Property shall be deposited in
the Protected Account maintained by

                                      -48-

<PAGE>

the Master Servicer no later than the close of business on each Determination
Date. The Master Servicer shall perform the tax reporting and withholding
related to foreclosures, abandonments and cancellation of indebtedness income as
specified by Sections 1445, 6050J and 6050P of the Code by preparing and filing
such tax and information returns, as may be required.

          In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Master Servicer shall dispose of such Mortgaged Property
prior to three years after its acquisition by the Trust Fund or, at the expense
of the Trust Fund, request more than 60 days prior to the day on which such
three- year period would otherwise expire, an extension of the three-year grace
period unless the Trustee shall have been supplied with an Opinion of Counsel
(such opinion not to be an expense of the Trustee) to the effect that the
holding by the Trust Fund of such Mortgaged Property subsequent to such
three-year period will not result in the imposition of taxes on "prohibited
transactions" of REMIC IA, REMIC IB, REMIC II or REMIC III as defined in section
860F of the Code or cause any of REMIC IA, REMIC IB, REMIC II or REMIC III to
fail to qualify as a REMIC at any time that any Certificates are outstanding, in
which case the Trust Fund may continue to hold such Mortgaged Property (subject
to any conditions contained in such Opinion of Counsel). Notwithstanding any
other provision of this Agreement, no Mortgaged Property acquired by the Trust
Fund shall be rented (or allowed to continue to be rented) or otherwise used for
the production of income by or on behalf of the Trust Fund in such a manner or
pursuant to any terms that would (i) cause such Mortgaged Property to fail to
qualify as "foreclosure property" within the meaning of section 860G(a)(8) of
the Code or (ii) subject any of REMIC IA, REMIC IB, REMIC II or REMIC III to the
imposition of any federal, state or local income taxes on the income earned from
such Mortgaged Property under section 860G(c) of the Code or otherwise, unless
the Master Servicer has agreed to indemnify and hold harmless the Trust Fund
with respect to the imposition of any such taxes.

          The decision of the Master Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by the Master Servicer that
the proceeds of such foreclosure would exceed the costs and expenses of bringing
such a proceeding. The income earned from the management of any Mortgaged
Properties acquired through foreclosure or other judicial proceeding, net of
reimbursement to the Master Servicer for expenses incurred (including any
property or other taxes) in connection with such management and net of
unreimbursed Servicing Fees, Advances, Servicing Advances and any management fee
paid or to be paid with respect to the management of such Mortgaged Property,
shall be applied to the payment of principal of, and interest on, the related
defaulted Mortgage Loans (with interest accruing as though such Mortgage Loans
were still current) and all such income shall be deemed, for all purposes in the
Agreement, to be payments on account of principal and interest on the related
Mortgage Notes and shall be deposited into the Protected Account maintained by
the Master Servicer. To the extent the income received during a Prepayment
Period is in excess of the amount attributable to amortizing principal and
accrued interest at the related Mortgage Rate on the related Mortgage Loan, such
excess shall be considered to be a partial Principal Prepayment for all purposes
hereof.

          The Liquidation Proceeds from any liquidation of a Mortgage Loan, net
of any payment to the Master Servicer as provided above, shall be deposited in
the Protected Account on the next succeeding Determination Date following
receipt thereof for distribution on the related

                                      -49-

<PAGE>

Distribution Date, except that any Excess Liquidation Proceeds shall be retained
by the Master Servicer as additional servicing compensation.

          The proceeds of any Liquidated Loan, as well as any recovery resulting
from a partial collection of Liquidation Proceeds or any income from an REO
Property, will be applied in the following order of priority: first, to
reimburse the Master Servicer for any related unreimbursed Servicing Advances
and Servicing Fees, pursuant to Section 4.02 or this Section 3.13; second, to
reimburse the Master Servicer for any unreimbursed Advances, pursuant to Section
4.02 or this Section 3.13; third, to accrued and unpaid interest (to the extent
no Advance has been made for such amount) on the Mortgage Loan or related REO
Property, at the Net Mortgage Rate to the first day of the month in which such
amounts are required to be distributed; and fourth, as a recovery of principal
of the Mortgage Loan.

          (b) On each Determination Date, the Master Servicer shall determine
the respective aggregate amounts of Excess Liquidation Proceeds and Realized
Losses, if any, for the related Prepayment Period.

          (c) The Master Servicer has no intent to foreclose on any Mortgage
Loan based on the delinquency characteristics as of the Closing Date; provided,
that the foregoing does not prevent the Master Servicer from initiating
foreclosure proceedings on any date hereafter if the facts and circumstances of
such Mortgage Loans including delinquency characteristics in the Master
Servicer's discretion so warrant such action.

     Section 3.14 SERVICING COMPENSATION.

     As compensation for its activities hereunder, the Master Servicer shall be
entitled to retain or withdraw from the Protected Account out of each payment of
interest on a Mortgage Loan included in the Trust Fund an amount equal to the
Servicing Fee.

     Additional servicing compensation in the form of any Excess Liquidation
Proceeds, assumption fees, prepayment charges, late payment charges, all income
and gain net of any losses realized from Permitted Investments with respect to
funds in or credited to the Protected Account shall be retained by the Master
Servicer to the extent not required to be deposited in the Protected Account
pursuant to Section 4.02. The Master Servicer shall be required to pay all
expenses incurred by it in connection with its servicing activities hereunder
(including payment of any premiums for hazard insurance, as required by Section
3.09 and maintenance of the other forms of insurance coverage required by
Section 3.11) and shall not be entitled to reimbursement therefor except as
specifically provided in Section 4.02.

     Section 3.15 REO PROPERTY.

          (a) In the event the Trust Fund acquires ownership of any REO Property
in respect of any related Mortgage Loan, the deed or certificate of sale shall
be issued to the Trustee, or to its nominee, on behalf of the related
Certificateholders. The Master Servicer shall sell any REO Property as
expeditiously as possible and in accordance with the provisions of this
Agreement.

                                      -50-

<PAGE>

Pursuant to its efforts to sell such REO Property, the Master Servicer shall
protect and conserve such REO Property in the manner and to the extent required
herein, subject to the REMIC Provisions.

          (b) The Master Servicer shall deposit all funds collected and received
in connection with the operation of any REO Property into the Protected Account
maintained by the Master Servicer.

          (c) The Master Servicer, upon the final disposition of any REO
Property, shall be entitled to reimbursement for any related unreimbursed
Advances, unreimbursed Servicing Advances or Servicing Fees from Liquidation
Proceeds received in connection with the final disposition of such REO Property;
provided, that any such unreimbursed Advances or Servicing Fees as well as any
unpaid Servicing Fees may be reimbursed or paid, as the case may be, prior to
final disposition, out of any net rental income or other net amounts derived
from such REO Property.

     Section 3.16 ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE.

          (a) The Master Servicer shall deliver to the Seller, the Guarantor,
the Trustee and the Rating Agencies within 120 days after the end of its fiscal
year, commencing with its fiscal year end in 2002, an Officer's Certificate,
certifying that with respect to the period ending on its fiscal year end: (i)
such Servicing Officer has reviewed the activities of the Master Servicer during
the preceding fiscal year or portion thereof and its performance under this
Agreement and (ii) to the best of such Servicing Officer's knowledge, based on
such review, the Master Servicer has performed and fulfilled its duties,
responsibilities and obligations under this Agreement in all material respects
throughout such year, or, if there has been a default in the fulfillment of any
such duties, responsibilities or obligations, specifying each such default known
to such Servicing Officer and the nature and status thereof, (iii) nothing has
come to the attention of such Servicing Officer to lead such Servicing Officer
to believe that any subservicer has failed to perform any of its duties,
responsibilities and obligations under its Subservicing Agreement in all
material respects throughout such year, or, if there has been a material default
in the performance or fulfillment of any such duties, responsibilities or
obligations, specifying each such default known to such Servicing Officer and
the nature and status thereof.

          (b) Copies of such statements shall be provided by the Trustee to any
Certificateholder upon request at the Master Servicer's expense, provided that
such statement shall have been delivered to the Trustee.

     Section 3.17 ANNUAL INDEPENDENT ACCOUNTANT'S SERVICING REPORT.

          The Master Servicer, at its expense, shall cause a nationally
recognized firm of independent certified public accountants to furnish a
statement to the Trustee, the Guarantor, the Rating Agencies and the Seller
within 120 days after the end of each fiscal year, commencing with the fiscal
year ending in 2002 to the effect that, with respect to the most recently ended
fiscal year, such firm has examined certain records and documents relating to
the Master Servicer's performance of its servicing obligations under this
Agreement and pooling and servicing and trust agreements in material respects
similar to this Agreement and to each other and that, on the basis of such
examination conducted substantially in compliance with the audit program for
mortgages serviced

                                      -51-

<PAGE>

for Freddie Mac or the Uniform Single Attestation Program for Mortgage Bankers,
such firm is of the opinion that the Master Servicer's activities have been
conducted in compliance with this Agreement, or that such examination has
disclosed no material items of noncompliance except for (i) such exceptions as
such firm believes to be immaterial, (ii) such other exceptions as are set forth
in such statement and (iii) such exceptions that the Uniform Single Attestation
Program for Mortgage Bankers or the Audit Program for Mortgages Serviced by
Freddie Mac requires it to report. Copies of such statements shall be provided
to any Certificateholder, upon request, by the Master Servicer, or by the
Trustee at the expense of the Master Servicer if the Master Servicer shall fail
to provide such copies. If any such report discloses exceptions that are
material, the Master Servicer shall advise the Trustee whether such exceptions
have been or are susceptible of cure, and will take prompt action to do so.

     Section 3.18  REPORTS FILED WITH SECURITIES AND EXCHANGE COMMISSION.

          Within 15 days after each Distribution Date, the Trustee shall, in
accordance with industry standards, file with the Commission via the Electronic
Data Gathering and Retrieval System ("EDGAR"), a Form 8-K and shall furnish a
copy of the monthly statement to the Certificateholders for such Distribution
Date as an exhibit thereto. Prior to January 30, 2003, the Trustee shall, in
accordance with industry standards and only if instructed by the Seller, file a
Form 15 Suspension Notice with respect to the Trust Fund, if applicable. Prior
to March 30, 2003, the Trustee shall file a Form 10-K, in substance conforming
to industry standards, with respect to the Trust Fund. The Seller hereby grants
to the Trustee a limited power of attorney to execute and file each such
document on behalf of the Seller. Such power of attorney shall continue until
either the earlier of (I) receipt by the Trustee from the Seller of written
termination of such power of attorney and (ii) the termination of the Trust
Fund. The Seller agrees to promptly furnish to the Trustee, from time to time
upon request, such further information, reports and financial statements within
its control related to this Agreement and the Mortgage Loans as the Trustee
reasonably deems appropriate to prepare and file all necessary reports with the
Commission. The Trustee shall have no responsibility to file any items other
than those specified in this Section 3.18; provided, however, the Trustee will
cooperate with the Seller in connection with any additional filings with respect
to the Trust Fund as the Seller deems necessary under the Securities Exchange
Act of 1934, as amended (the "Exchange Act"). Copies of all reports filed by the
Trustee under the Exchange Act shall be sent to: the Seller c/o Bear, Stearns &
Co. Inc., Attn: Managing Director-Analysis and Control, One Metrotech Center
North, Brooklyn, New York 11202-3859. Fees and expenses incurred by the Trustee
in connection with this Section 3.18 shall not be reimbursable from the Trust
Fund.

     Section 3.19 ACCESS TO CERTAIN DOCUMENTATION.

          The Master Servicer shall provide to the OTS and the FDIC and to
comparable regulatory authorities supervising holders of the Certificates and
the examiners and supervisory agents of the OTS, the FDIC and such other
authorities, and to the Guarantor, access to any documentation as may be held by
the Master Servicer regarding the Mortgage Loans required by applicable
regulations of the OTS and the FDIC. Such access shall be afforded without
charge, but only upon reasonable and prior written request and during normal
business hours at the offices of the Master Servicer designated by it. Nothing
in this Section shall limit the obligation of the Master Servicer to observe any
applicable law prohibiting disclosure of information regarding the

                                      -52-

<PAGE>

Mortgagors and the failure of the Master Servicer to provide access as provided
in this Section as a result of such obligation shall not constitute a breach of
this Section.

     Section 3.20 OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.

     Beginning on the first Business Day of the fiscal quarter immediately
following the date on which a Mortgage Loan has become at least 91 days
delinquent, the Seller may, at its option, purchase such Mortgage Loan from the
Trustee at the Purchase Price therefor. If at any time the Seller makes a
payment to the Protected Account maintained by the Master Servicer, covering the
amount of the Purchase Price for such Mortgage Loan, and the Seller provides to
the Trustee a certification signed by a Servicing Officer stating that the
amount of such payment has been deposited in such Protected Account then the
Trustee shall execute the assignment of such Mortgage Loan at the request of the
Seller without recourse to the Seller which shall succeed to all the Trustee's
right, title and interest in and to such Mortgage Loan, and all security and
documents relative thereto. Such assignment shall be an assignment outright and
not for security. The Seller will thereupon own such Mortgage Loan, and all such
security and documents, free of any further obligation to the Trustee or the
Certificateholders with respect thereto. Notwithstanding the foregoing, any such
optional right of repurchase by the Seller hereunder with respect to a
delinquent Mortgage Loan shall, if unexercised, terminate on the earlier of (i)
the date on which such delinquency has been cured or (ii) the last Business Day
of such fiscal quarter immediately following the date on which such Mortgage
Loan became 91 days delinquent, provided however, that such optional right of
repurchase shall be reinstated if (a) in the case of clause (I), the related
Mortgage Loan shall thereafter again have become 91 or more days delinquent and
(b) in the case of clause (ii), such delinquency shall have been subsequently
cured and the related Mortgage Loan shall thereafter again become 91 or more
days delinquent in any subsequent fiscal quarter.

     In addition, the Guarantor shall have the right to purchase a Mortgage Loan
from Loan Group 1 or Loan Group 2 on the first Business Day immediately
following the date on which a Mortgage Loan has become at least 91 days
delinquent at the Purchase Price therefor if the Seller does not exercise such
right in the manner set forth above; provided, however, the Guarantor shall not
be subject to the restrictions set forth in the last sentence of the preceding
paragraph.

     Section 3.21 AGREEMENT TO APPOINT SPECIAL SERVICER.

          (a) The Guarantor may require the Master Servicer to enter into a
special subservicing agreement with a servicer with expertise in servicing
delinquent mortgage loans as designated by the Guarantor (the "Special
Servicer") on or after the earliest Distribution Date with respect to which the
aggregate Current Principal Amount of the Class B-3 Certificates has been
reduced to zero. The Rating Agencies shall be notified of the appointment of any
such Special Servicer. Such special subservicing agreement shall relate to the
servicing of only Group 1 and Group 2 Mortgage Loans that (x) have been
delinquent in payment with respect to three or more Monthly Payments (provided,
however, that the third such Monthly Payment shall not be deemed to be
delinquent for purposes of this clause (x) until the close of business on the
last day of the month in which such Monthly Payment first became due) and (y)
have been transferred to the Special Servicer in accordance with this Section
3.21 and the related special subservicing agreement (a "Specially Serviced
Mortgage Loan").

                                      -53-

provisions of this Agreement, including but not limited to this Section 3.21,
Section 3.03 and Section 3.04, except as provided otherwise in this Section
3.21. In addition, the special subservicing agreement shall be on terms which
shall be reasonably acceptable to the Guarantor and the Master Servicer and

          (A) the Special Servicer shall at all times, meet the eligibility
          criteria described in Section 3.03;

          (B) the Special Servicer shall service only the Specially Serviced
          Mortgage Loans in a manner consistent with the provisions with this
          Agreement except as provided otherwise in the special subservicing
          agreement;

          (C) the Special Servicer shall use the Fannie Mae foreclosure network
          (and pay the customary fees therefor) for foreclosures and
          bankruptcies relating to Specially Serviced Mortgage Loans;

          (D) the Special Servicer shall use the Fannie Mae disposition service
          (and pay the customary fees therefor) for the disposition of REO
          Property related to Specially Serviced Mortgage Loans;

          (E) the Special Servicer shall make Servicing Advances on the
          Specially Serviced Mortgage Loans to the same extent and in the same
          manner as the Master Servicer with respect to the Group 1 or Group 2
          Mortgage Loans pursuant to this Agreement;

          (F) the Special Servicer shall be entitled to receive the Servicing
          Fee with respect to all Specially Serviced Mortgage Loans;

          (G) prior to the transfer of servicing to the Special Servicer, the
          Master Servicer and the Special Servicer shall have provided all
          notices relating to such transfer of servicing as required to be
          delivered to the borrowers by applicable state and federal law;

          (H) the Special Servicer shall indemnify the Master Servicer, the
          Trust Administrator and the Trustee for any liabilities to them
          arising from failures of the Special Servicer to perform its
          obligations according to the terms of the subservicing agreement;

          (I) the Master Servicer shall promptly give notice thereof to the
          Trustee and the Guarantor of the transfer of servicing to the Special
          Servicer, including the loan number together with the borrower's name
          and the unpaid principal balance of the transferred Mortgage Loan at
          the time of transfer;

          (J) each of the respective obligations, duties, and liabilities of the
          Master Servicer and the Special Servicer (or either of them) with
          respect to the servicing of

                                      -54-

<PAGE>

          the Specially Serviced Mortgage Loans that have arisen prior to the
          date on which the servicing of such Specially Serviced Mortgage Loan
          was transferred to the Special Servicer (the "Effective Date"), or
          that arise on and after the Effective Date, under this Agreement and
          the subservicing agreement and that remain unperformed or unsatisfied
          shall survive any transfer of servicing;

          (K) once a Group 1 or Group 2 Mortgage Loan becomes a Specially
          Serviced Mortgage Loan, such Mortgage Loan shall remain a Specially
          Serviced Mortgage Loan, and shall continue to be serviced by the
          Special Servicer, until the earlier of the liquidation or other
          disposition of such Mortgage Loan or the termination of the
          subservicing agreement, regardless of delinquency status or otherwise;

          (L) the Guarantor may remove the Special Servicer if the Special
          Servicer at any time fails to meet any of the above criteria or
          otherwise, in the judgment of the Guarantor, fails to perform
          according to the terms of the subservicing agreement and the
          provisions of this Section 3.21; provided that prior to any such
          removal the Guarantor shall designate a successor Special Servicer
          meeting the requirements of this Section 3.21, and no removal of a
          Special Servicer shall be effective until a successor Special Servicer
          has entered into a special subservicing agreement meeting the
          requirements of this Section 3.21 and agreed to assume the duties of
          the Special Servicer or the Master Servicer has undertaken such
          duties; and

          (M) in connection with any transfer of a Group 1 or Group 2 Mortgage
          Loan to the Special Servicer as a Specially Serviced Mortgage Loan,
          the Master Servicer shall execute any appropriate assignments or other
          documents reasonable and necessary to further the prosecution of the
          Special Servicer obligations under the special subservicing agreement.

                                    Accounts

     Section 4.01 COLLECTION OF MORTGAGE LOAN PAYMENTS; PROTECTED ACCOUNT.

          (a) The Master Servicer shall make reasonable efforts in accordance
with customary and usual standards of practice of prudent mortgage lenders in
the respective states in which the Mortgaged Properties are located to collect
all payments called for under the terms and provisions of the Mortgage Loans to
the extent such procedures shall be consistent with this Agreement and the terms
and provisions of any related Required Insurance Policy. Consistent with the
foregoing, the Master Servicer may in its discretion (i) waive any late payment
charge and (ii) extend the due dates for payments due on a Mortgage Note for a
period not greater than 125 days. In the event of any such arrangement, the
Master Servicer shall make Advances on the related Mortgage Loan during the
scheduled period in accordance with the amortization schedule of such Mortgage
Loan without modification thereof by reason of such arrangements, and shall be
entitled to reimbursement therefor in accordance with Section 6.05. The Master
Servicer shall not be required to institute or join in litigation with respect
to collection of any payment (whether under a Mortgage, Mortgage Note or
otherwise or against any public or governmental authority with respect to a
taking or condemnation) if it reasonably believes that enforcing the provision
of the Mortgage or other instrument pursuant to which such payment is required
is prohibited by applicable law. In addition, if (x) a Mortgage Loan is in
default or default is imminent or (y) the Master Servicer delivers to the
Trustee a certification, based on the advice of counsel or certified public
accountants, in either case, that have a national reputation with respect to
taxation of REMICs, that a modification of such Mortgage Loan will not result in
the imposition of taxes on or disqualify any of REMIC IA, REMIC IB, REMIC II or
REMIC III, the Master Servicer may, (A) amend the related Mortgage Note to
reduce the Mortgage Rate applicable thereto and (B) amend any Mortgage Note to
extend to the maturity thereof. However, if the Current Principal Amount of the
Class B-3 Certificates has been reduced to zero, , the Master Servicer shall not
take any action pursuant to the preceding sentence with respect to a Group 1 or
Group 2 Mortgage Loan without obtaining the prior written consent of the
Guarantor to such modification. The Master Servicer shall submit to the
Guarantor with its request for consent, such information related to the proposed
modification as can be expected to be needed by the Guarantor to evaluate the
Master Servicer's request, including the terms of the proposed modification and
the reasons for the Master Servicer's decision that such Group 1 or Group 2
Mortgage Loan should be modified. The Guarantor shall be deemed to have
consented to the Master Servicer's request in the event that the Guarantor does
not either provide the Master Servicer with its written consent to such
requested modification or written notice of its objection to such modification
within five Business Days of its receipt of the Master Servicer's request.
Requests for modification shall be sent to the Guarantor at: Fannie Mae, 3900
Wisconsin Avenue, N.W., Washington, D.C. 20016, Attn: Vice President-Loss
Mitigation. With respect to each Group 1 or Group 2 Mortgage Loan which is
modified after the Current Principal Amount of the Class B-3 Certificates has
been reduced to zero, the Master Servicer shall give written notice to the
Guarantor to the following address: Fannie Mae, 4000 Wisconsin Avenue, N.W.,
Washington, D.C. 20016, Attn: Bond Administration. Such notice shall be
delivered within thirty Business Days following such modification and shall
include information with respect to the modification, including, without

                                      -56-

<PAGE>

limitation, the interest rate, the principal balance and the maturity date of
such Group 1 or Group 2 Mortgage Loan before and after such modification.

          (b) The Master Servicer shall establish and maintain a Protected
Account (which shall at all times be an Eligible Account) with a Depository
institution in the name of the Master Servicer for the benefit of the Trustee on
behalf of the Certificateholders and designated "Wells Fargo Bank Minnesota,
National Association, in trust for registered holders of Structured Asset
Mortgage Securities Inc., Bear Stearns ARM Trust, Mortgage Pass-Through
Certificates, Series 2002-1". The Master Servicer shall deposit or cause to be
deposited into the Protected Account on a daily basis within one Business Day of
receipt, except as otherwise specifically provided herein, the following
payments and collections remitted by subservicers or received by it in respect
of Mortgage Loans subsequent to the Cut-off Date (other than in respect of
principal and interest due on the Mortgage Loans on or before the Cut-off Date)
and the following amounts required to be deposited hereunder:

          (i) all payments on account of principal, including Principal
     Prepayments, on the Mortgage Loans;

          (ii) all payments on account of interest on the Mortgage Loans net of
     the related Servicing Fee permitted under Section 3.14;

          (iii) all Liquidation Proceeds, other than proceeds to be applied to
     the restoration or repair of the Mortgaged Property or released to the
     Mortgagor in accordance with the Master Servicer's normal servicing
     procedures;

          (iv) any amount required to be deposited by the Master Servicer
     pursuant to Section 4.01(c) in connection with any losses on Permitted
     Investments;

          (vi) any amounts required to be deposited by the Master Servicer
     pursuant to Section 3.09;

          (vii) the Purchase Price for any Mortgage Loan repurchased by the
     Seller pursuant to Sections 2.02, 2.03 or 3.20 of this Agreement and any
     Substitution Adjustment Amount relating to a Mortgage Loan; and

          (viii) any other amounts required to be deposited hereunder.

          The foregoing requirements for remittance by the Master Servicer into
the Protected Account shall be exclusive, it being understood and agreed that,
without limiting the generality of the foregoing, payments in the nature of late
payment charges or assumption fees, if collected, need not be remitted by the
Master Servicer. In the event that the Master Servicer shall remit any amount
not required to be remitted and not otherwise subject to withdrawal pursuant to
Section 4.02, it may at any time withdraw or direct the institution maintaining
the Protected Account, to withdraw such amount from the Protected Account, any
provision herein to the contrary notwithstanding. Such withdrawal or direction
may be accomplished by delivering written notice thereof to the institution
maintaining the Protected Account, that describes the amounts deposited in error
in the Protected

                                      -57-

<PAGE>

Account. The Master Servicer shall maintain adequate records with respect to all
withdrawals made pursuant to this Section. All funds deposited in the Protected
Account shall be held in trust for the Certificateholders until withdrawn in
accordance with Section 4.02.

          (c) The institution that maintains the Protected Account shall invest
the funds in the Protected Account, in the manner directed by the Master
Servicer, in Permitted Investments which shall mature not later than the second
Business Day next preceding the related Distribution Account Deposit Date
(except that if such Permitted Investment is an obligation of the institution
that maintains such Protected Account, then such Permitted Investment shall
mature not later than the Business Day next preceding such Distribution Account
Deposit Date) and shall not be sold or disposed of prior to its maturity. All
such Permitted Investments shall be made in the name of the Trustee, for the
benefit of the Certificateholders. All income and gain net of any losses
realized from any such investment shall be for the benefit of the Master
Servicer as servicing compensation and shall be remitted to it monthly as
provided herein. The amount of any losses incurred in the Protected Account in
respect of any such investments shall be deposited by the Master Servicer into
the Protected Account, out of the Master Servicer's own funds.

          (d) The Master Servicer shall give at least 30 days advance notice to
the Trustee, the Guarantor, each Rating Agency and the Seller of any proposed
change of location of the Protected Account prior to any change thereof.

     Section 4.02 PERMITTED WITHDRAWALS FROM THE PROTECTED ACCOUNT.

          (a) The Master Servicer may from time to time make withdrawals from
the Protected Account for the following purposes:

          (i) to pay itself (to the extent not previously paid to or withheld by
     the Master Servicer), as servicing compensation in accordance with Section
     3.14, that portion of any payment of interest that equals the Servicing Fee
     for the period with respect to which such interest payment was made, and,
     as additional servicing compensation, those other amounts set forth in
     Section 3.14;

          (ii) to reimburse the Master Servicer for Advances made by it with
     respect to the Mortgage Loans, provided, however, that the Master
     Servicer's right of reimbursement pursuant to this subclause (ii) shall be
     limited to amounts received on particular Mortgage Loan(s) (including, for
     this purpose, Liquidation Proceeds) that represent late recoveries of
     payments of principal and/or interest on such particular Mortgage Loan(s)
     in respect of which any such Advance was made;

          (iii) to reimburse the Master Servicer for any previously made portion
     of a Servicing Advance or an Advance made by the Master Servicer that, in
     the good faith judgment of the Master Servicer, will not be ultimately
     recoverable by it from the related Mortgagor, any related Liquidation
     Proceeds or otherwise (a "Nonrecoverable Advance"), to the extent not
     reimbursed pursuant to clause (ii) or clause (v);

                                      -58-

<PAGE>

          (iv) to reimburse the Master Servicer from Insurance Proceeds for
     Insured Expenses covered by the related Insurance Policy;

          (v) to pay the Master Servicer any unpaid Servicing Fees and to
     reimburse it for any unreimbursed Servicing Advances, provided, however,
     that the Master Servicer's right to reimbursement for Servicing Advances
     pursuant to this subclause (v) with respect to any Mortgage Loan shall be
     limited to amounts received on particular Mortgage Loan(s) (including, for
     this purpose, Liquidation Proceeds and purchase and repurchase proceeds)
     that represent late recoveries of the payments for which such Servicing
     Advances were made;

          (vi) to pay to the Seller, the Seller or itself, as applicable, with
     respect to each Mortgage Loan or property acquired in respect thereof that
     has been purchased pursuant to Section 2.02 or 2.03 of this Agreement, all
     amounts received thereon and not taken into account in determining the
     related Stated Principal Balance of such repurchased Mortgage Loan;

          (vii) to pay any expenses recoverable by the Master Servicer pursuant
     to Sections 3.03, 7.01, 7.03, 7.04 and 9.05 of this Agreement;

          (viii) to withdraw pursuant to Section 4.01 any amount deposited in
     the Protected Account and not required to be deposited therein; and

          (ix) to clear and terminate the Protected Account upon termination of
     this Agreement pursuant to Section 10.01 hereof.

          In addition, no later than 1:00 p.m. Eastern time on the Distribution
Account Deposit Date, the Master Servicer shall withdraw from the Protected
Account and remit to the Trustee the amount of Available Funds collected, to the
extent on deposit, and the Trustee shall deposit such amount in the Distribution
Account. In addition, on or before the Distribution Account Deposit Date, the
Master Servicer shall remit to the Trustee for deposit in the Distribution
Account any Advances or any payments of Compensating Interest required to be
made by the Master Servicer with respect to the Mortgage Loans.

          The Master Servicer shall keep and maintain separate accounting, on a
Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Protected Account pursuant to subclauses (i), (ii), (iv),
(v) and (vi) above. Prior to making any withdrawal from the Protected Account
pursuant to subclause (iii), the Master Servicer shall deliver to the Trustee an
Officer's Certificate of a Servicing Officer indicating the amount of any
previous Advance or Servicing Advance determined by the Master Servicer to be a
Nonrecoverable Advance and identifying the related Mortgage Loan(s), and their
respective portions of such Nonrecoverable Advance.

     Section 4.03 COLLECTION OF TAXES; ASSESSMENTS AND SIMILAR ITEMS; ESCROW
                  ACCOUNTS.

          To the extent required by the related Mortgage Note, the Master
Servicer shall establish and maintain one or more accounts (each, an "Escrow
Account") and deposit and retain

                                      -59-

<PAGE>

therein all collections from the Mortgagors (or advances by the Master Servicer)
for the payment of taxes, assessments, hazard insurance premiums or comparable
items for the account of the Mortgagors. Nothing herein shall require the Master
Servicer to compel a Mortgagor to establish an Escrow Account in violation of
applicable law.

          Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums, condominium or PUD association dues, or comparable items, to reimburse
the Master Servicer out of related collections for any payments made pursuant to
Section 3.01 (with respect to taxes and assessments and insurance premiums) and
Section 3.09 (with respect to hazard insurance), to refund to any Mortgagors any
sums as may be determined to be overages, to pay interest, if required by law or
the terms of the related Mortgage or Mortgage Note, to Mortgagors on balances in
the Escrow Account or to clear and terminate the Escrow Account at the
termination of this Agreement in accordance with Section 10.01 thereof. The
Escrow Account shall not be a part of the Trust Fund.

     Section 4.04 DISTRIBUTION ACCOUNT.

          (a) The Trustee shall establish and maintain in the name of the
Trustee, for the benefit of the Certificateholders, the Distribution Account as
a segregated trust account or accounts.

          (b) All amounts deposited to the Distribution Account shall be held by
the Trustee in the name of the Trustee in trust for the benefit of the
Certificateholders in accordance with the terms and provisions of this
Agreement.

          (c) The Distribution Account shall constitute an Eligible Account of
the Trust Fund segregated on the books of the Trustee and held by the Trustee
and the Distribution Account and the funds deposited therein shall not be
subject to, and shall be protected from, all claims, liens, and encumbrances of
any creditors or depositors of the Trustee (whether made directly, or indirectly
through a liquidator or receiver of the Trustee). The amount at any time
credited to the Distribution Account may be invested in the name of the Trustee,
in such Permitted Investments, or deposited in demand deposits with such
depository institutions, as determined by the Trustee. All Permitted Investments
shall mature or be subject to redemption or withdrawal on or before, and shall
be held until, the next succeeding Distribution Date if the obligor for such
Permitted Investment is the Trustee or, if such obligor is any other Person, the
Business Day preceding such Distribution Date. All investment earnings on
amounts on deposit in the Distribution Account or benefit from funds uninvested
therein from time to time shall be for the account of the Trustee. The Trustee
shall be permitted to withdraw or receive distribution of any and all investment
earnings from the Distribution Account on each Distribution Date. If there is
any loss on a Permitted Investment or demand deposit, the Trustee shall deposit
the amount of the loss in the Distribution Account. With respect to the
Distribution Account and the funds deposited therein, the Trustee shall take
such action as may be necessary to ensure that the Certificateholders shall be
entitled to the priorities afforded to such a trust account (in addition to a
claim against the estate of the Trustee) as provided by 12 U.S.C. ss. 92a(e),
and applicable regulations pursuant thereto, if applicable, or any applicable
comparable state statute applicable to state chartered banking corporations.

          (a) The Trustee will, from time to time, make or cause to be made such
withdrawals or transfers from the Distribution Account as follows:

          (i) to reimburse the Trustee for expenses, costs and liabilities
     incurred by or reimbursable to it pursuant to this Agreement;

          (ii) to pay investment income to the Trustee;

          (iii) to pay the Trustee Fee to the Trustee;

          (iv) to remove amounts deposited in error; and

          (v) to clear and terminate the Distribution Account pursuant to
     Section 10.01.

          (b) On each Distribution Date, the Trustee shall distribute the
Available Funds in the Distribution Account to the holders of the Certificates
in accordance with Section 6.01.

     Section 4.06 THE GUARANTY. On each Distribution Date following receipt of a
statement (as set forth in Section 6.04) that indicates a Deficiency Amount for
such Distribution Date, the Guarantor shall distribute to the Trustee for
payment to the Class I-A Certificates and Class II-A- Certificates a Guarantor
Payment in an aggregate amount equal to the Deficiency Amount for such
Distribution Date directly to the Holders of the Guaranteed Certificates,
without first depositing such amount in the Distribution Account, as follows:

                                  Certificates

     Section 5.01 CERTIFICATES. (a) The Depository, the Seller and the Trustee
have entered into a Depository Agreement dated as of the Closing Date (the
"Depository Agreement"). Except for the Residual Certificates, the Private
Certificates and the Individual Certificates, the Certificates shall at all
times remain registered in the name of the Depository or its nominee and at all
times: (i) registration of such Certificates may not be transferred by the
Trustee except to a successor to the Depository; (ii) ownership and transfers of
registration of such Certificates on the books of the Depository shall be
governed by applicable rules established by the Depository; (iii) the Depository
may collect its usual and customary fees, charges and expenses from its
Depository Participants; (iv) the Trustee shall deal with the Depository as
representative of such Certificate Owners of the respective Class of
Certificates for purposes of exercising the rights of Certificateholders under
this Agreement, and requests and directions for and votes of such representative
shall not be deemed to be inconsistent if they are made with respect to
different Certificate Owners; and (v) the Trustee may rely and shall be fully
protected in relying upon information furnished by the Depository with respect
to its Depository Participants.

     The Residual Certificates and the Private Certificates are initially
Physical Certificates. If at any time the Holders of all of the Certificates of
one or more such Classes request that the Trustee cause such Class to become
Global Certificates, the Trustee and the Seller will take such action as may be
reasonably required to cause the Depository to accept such Class or Classes for
trading if it may legally be so traded.

     All transfers by Certificate Owners of such respective Classes of
Book-Entry Certificates and any Global Certificates shall be made in accordance
with the procedures established by the Depository Participant or brokerage firm
representing such Certificate Owners. Each Depository Participant shall only
transfer Book-Entry Certificates of Certificate Owners it represents or of
brokerage firms for which it acts as agent in accordance with the Depository's
normal procedures.

     (b) If (i)(A) the Seller advises the Trustee in writing that the Depository
is no longer willing or able to properly discharge its responsibilities as
Depository and (B) the Trustee or the Seller is unable to locate a qualified
successor within 30 days or (ii) the Seller at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the
Depository, the Trustee shall request that the Depository notify all Certificate
Owners of the occurrence of any such event and of the availability of
definitive, fully registered Certificates to Certificate Owners requesting the
same. Upon surrender to the Trustee of the Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall issue the definitive Certificates. Neither the Seller nor the
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.

     (1) The Class I-A Certificates will bear interest at a variable
Pass-Through Rate equal to the weighted average of the Net Rates of the Group 1
Mortgage Loans, weighted on the basis of the respective Scheduled Principal
Balances of each such Mortgage Loan as of the beginning of the Due Period
immediately preceding the related Distribution Date, net of the Guaranty Fee for
such Distribution Date. The Pass-Through Rate with respect to the first Interest
Accrual Period is expected to be approximately 6.772% per annum.

     (2) The Class II-A Certificates will bear interest at a variable
Pass-Through Rate equal to the weighted average of the Net Rates of the Group 2
Mortgage Loans, weighted on the basis of the respective Scheduled Principal
Balances of each such Mortgage Loan as of the beginning of the Due Period
immediately preceding the related Distribution Date, net of the Guaranty Fee for
such Distribution Date. The Pass-Through Rate with respect to the first interest
accrual period is expected to be approximately 6.980% per annum.

     (3) The Class III-A Certificates and the Class R Certificates will bear
interest at a variable Pass-Through Rate equal to the weighted average of the
Net Rates of the Group 3 Mortgage Loans, weighted on the basis of the respective
Scheduled Principal Balances of each such Mortgage Loan as of the beginning of
the Due Period immediately preceding the related Distribution Date. The
Pass-Through Rate with respect to the first interest accrual period is expected
to be approximately 6.874% per annum.

     (4) The Class B-1, Class B-2, Class B-3, Class B-4, Class B-5 and Class B-6
Certificates will bear interest at a variable Pass-Through Rate equal to the
weighted average of the Pass-Through Rates on each REMIC II Regular Interest
ending with the designation "A"; provided that for purposes of such weighted
average, the Pass-Through Rate of each such REMIC II Regular Interest shall be
subject to a cap and a floor equal to the weighted average of the Net Rates of
the Mortgage Loans in the related Group. The Pass-Through Rates with respect to
the first interest accrual period is expected to be approximately 6.923% per
annum.

     (5) In respect of the Class R-III Interest.

     (d) Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
regulations, the Distribution Date immediately following the maturity date for
the Mortgage Loan with the latest maturity date in the Trust Fund has been
designated as the "latest possible maturity date" for the REMIC IA Regular
Interests, the REMIC IB Regular Interests, the REMIC II Regular Interests and
the REMIC Regular Certificates.

     (e) With respect to each Distribution Date, each Class of Certificates
shall accrue interest during the related Interest Accrual Period. With respect
to each Distribution Date and each such

                                      -65-

<PAGE>

Class of Certificates, interest shall be calculated, on the basis of a 360-day
year comprised of twelve 30-day months, based upon the respective Pass-Through
Rate set forth, or determined as provided, above and the Current Principal
Amount of such Class applicable to such Distribution Date.

     (f) The Certificates shall be substantially in the forms set forth in
Exhibits A-1, A-2 and A-3. On original issuance, the Trustee shall sign,
countersign and shall deliver them at the direction of the Seller. Pending the
preparation of definitive Certificates of any Class, the Trustee may sign and
countersign temporary Certificates that are printed, lithographed or
typewritten, in authorized denominations for Certificates of such Class,
substantially of the tenor of the definitive Certificates in lieu of which they
are issued and with such appropriate insertions, omissions, substitutions and
other variations as the officers or authorized signatories executing such
Certificates may determine, as evidenced by their execution of such
Certificates. If temporary Certificates are issued, the Seller will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the office of the Trustee, without charge to the Holder. Upon
surrender for cancellation of any one or more temporary Certificates, the
Trustee shall sign and countersign and deliver in exchange therefor a like
aggregate principal amount, in authorized denominations for such Class, of
definitive Certificates of the same Class. Until so exchanged, such temporary
Certificates shall in all respects be entitled to the same benefits as
definitive Certificates.

     (g) Each Class of Book-Entry Certificates will be registered as a single
Certificate of such Class held by a nominee of the Depository or the DTC
Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of (i) in the
case of the Senior Certificates (other than the Residual Certificates), $1,000
and in each case increments of $1.00 in excess thereof, and (ii) in the case of
the Offered Subordinate Certificates, $25,000 and increments of $1.00 in excess
thereof, except that one Certificate of each such Class may be issued in a
different amount so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Current Principal Amount of such
Class on the Closing Date. On the Closing Date, the Trustee shall execute and
countersign Physical Certificates all in an aggregate principal amount that
shall equal the Current Principal Amount of such Class on the Closing Date. The
Residual Certificates shall be issued in certificated fully-registered form in
the denomination of $50. Each Class of Global Certificates, if any, shall be
issued in fully registered form in minimum dollar denominations of $50,000 and
integral multiples of $1.00 in excess thereof, except that one Certificate of
each Class may be in a different denomination so that the sum of the
denominations of all outstanding Certificates of such Class shall equal the
Current Principal Amount of such Class on the Closing Date. On the Closing Date,
the Trustee shall execute and countersign (i) in the case of each Class of
Offered Certificates, the Certificate in the entire Current Principal Amount of
the respective Class and (ii) in the case of each Class of Private Certificates,
Individual Certificates all in an aggregate principal amount that shall equal
the Current Principal Amount of each such respective Class on the Closing Date.
The Certificates referred to in clause (i) and if at any time there are to be
Global Certificates, the Global Certificates shall be delivered by the Seller to
the Depository or pursuant to the Depository's instructions, shall be delivered
by the Seller on behalf of the Depository to and deposited with the DTC
Custodian. The Trustee shall sign the Certificates by facsimile or manual
signature and countersign them by manual signature on behalf of the Trustee by
one or more authorized signatories, each of whom shall be Responsible Officers
of the Trustee

                                      -66-

or its agent. A Certificate bearing the manual and facsimile signatures of
individuals who were the authorized signatories of the Trustee or its agent at
the time of issuance shall bind the Trustee, notwithstanding that such
individuals or any of them have ceased to hold such positions prior to the
delivery of such Certificate.

     (h) No Certificate shall be entitled to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Certificate the
manually executed countersignature of the Trustee or its agent, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates issued on the Closing Date shall be dated the Closing Date. All
Certificates issued thereafter shall be dated the date of their
countersignature.

     (i) The Closing Date is hereby designated as the "startup" day of each
REMIC within the meaning of Section 860G(a)(9) of the Code.

     (j) For federal income tax purposes, each REMIC shall have a tax year that
is a calendar year and shall report income on an accrual basis.

     (k) The Trustee on behalf of the Trust shall cause each REMIC to timely
elect to be treated as a REMIC under Section 860D of the Code. Any
inconsistencies or ambiguities in this Agreement or in the administration of any
Trust established hereby shall be resolved in a manner that preserves the
validity of such elections.

     (l) The following legend shall be placed on the Residual Certificates and
Private Certificates, whether upon original issuance or upon issuance of any
other Certificate of any such Class in exchange therefor or upon transfer
thereof:

Trustee shall maintain at its Corporate Trust Office a Certificate Register in
which, subject to such reasonable regulations as it may prescribe, the Trustee
shall provide for the registration of Certificates and of transfers and

     (b) Subject to Subsection 5.01(a) and, in the case of any Global
Certificate or Physical Certificate upon the satisfaction of the conditions set
forth below, upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee maintained for such purpose, the Trustee

transferee or transferees, a new Certificate of a like Class and aggregate
Fractional Undivided Interest, but bearing a different number.

     (c) By acceptance of an Individual Certificate, whether upon original
issuance or subsequent transfer, each holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth in the Securities
Legend and agrees that it will transfer such a Certificate only as provided
herein. In addition to the provisions of Subsection 5.02(h), the following
restrictions shall apply with respect to the transfer and registration of
transfer of an Individual Certificate to a transferee that takes delivery in the

     Certificate if the requested transfer is being made to a transferee who has
     provided the Trustee with a Rule 144A Certificate or comparable evidence as
     to its QIB status.

          (ii) The Trustee shall register the transfer of any Individual
     Certificate if (x) the transferor has advised the Trustee in writing that
     the Certificate is being transferred to an Institutional Accredited
     Investor; and (y) prior to the transfer the transferee furnishes to the
     Trustee an Investment Letter (and the Trustee shall be fully protected in
     so doing), provided that, if based upon an Opinion of Counsel to the effect
     that the delivery of (x) and (y) above are not sufficient to confirm that
     the proposed transfer is being made pursuant to an exemption from, or in a
     transaction not subject to, the registration requirements of the Securities
     Act and other applicable laws, the Trustee shall as a condition of the
     registration of any such transfer require the transferor to furnish such
     other certifications, legal opinions or other information prior to
     registering the transfer of an Individual Certificate as shall be set forth
     in such Opinion of Counsel.

     (d) Subject to Subsection 5.02(h), so long as a Global Certificate of such
Class is outstanding and is held by or on behalf of the Depository, transfers of
beneficial interests in such Global Certificate, or transfers by holders of

form of beneficial interests in the Global Certificate, may be made only in
accordance with this Subsection 5.02(d) and in accordance with the rules of the
Depository:

     or Certificates and the Trustee shall register such transfer only upon
     compliance with the provisions of Subsection 5.02(c)(ii).

                                      -68-

     set forth in clause (i) above, the Trustee shall register such transfer
     only upon compliance with the provisions of Subsection 5.02(c)(i).

          (iii) In the case of an Individual Certificate of a Class being
     transferred to a transferee that takes delivery in the form of a beneficial
     interest in a Global Certificate of such Class, the Trustee shall register
     such transfer if the transferee has provided the Trustee with a Rule 144A
     Certificate or comparable evidence as to its QIB status.

          (iv) No restrictions shall apply with respect to the transfer or
     registration of transfer of a beneficial interest in the Global Certificate
     of a Class to a transferee that takes delivery in the form of a beneficial
     interest in the Global Certificate of such Class; provided that each such
     transferee shall be deemed to have made such representations and warranties
     contained in the Rule 144A Certificate as are sufficient to establish that
     it is a QIB.

     (e) Subject to Subsection 5.02(h), an exchange of a beneficial interest in
a Global Certificate of a Class for an Individual Certificate or Certificates of
such Class, an exchange of an Individual Certificate or Certificates of a Class
for a beneficial interest in the Global Certificate of such Class and an
exchange of an Individual Certificate or Certificates of a Class for another
Individual Certificate or Certificates of such Class (in each case, whether or
not such exchange is made in anticipation of subsequent transfer, and, in the
case of the Global Certificate of such Class, so long as such Certificate is
outstanding and is held by or on behalf of the Depository) may be made only in
accordance with this Subsection 5.02(e) and in accordance with the rules of the
Depository:

          (i) A holder of a beneficial interest in a Global Certificate of a
     Class may at any time exchange such beneficial interest for an Individual
     Certificate or Certificates of such Class.

          (ii) A holder of an Individual Certificate or Certificates of a Class
     may exchange such Certificate or Certificates for a beneficial interest in
     the Global Certificate of such Class if such holder furnishes to the
     Trustee a Rule 144A Certificate or comparable evidence as to its QIB
     status.

          (iii) A holder of an Individual Certificate of a Class may exchange
     such Certificate for an equal aggregate principal amount of Individual
     Certificates of such Class in different authorized denominations without
     any certification.

     (f) (i) Upon acceptance for exchange or transfer of an Individual
Certificate of a Class for a beneficial interest in a Global Certificate of such
Class as provided herein, the Trustee shall cancel such Individual Certificate
and shall (or shall request the Depository to) endorse on the schedule affixed
to the applicable Global Certificate (or on a continuation of such schedule
affixed to the Global Certificate and made a part thereof) or otherwise make in
its books and records an appropriate notation evidencing the date of such
exchange or transfer and an increase in the certificate balance of the Global
Certificate equal to the certificate balance of such Individual Certificate
exchanged or transferred therefor.

          (ii) Upon acceptance for exchange or transfer of a beneficial interest
     in a Global Certificate of a Class for an Individual Certificate of such
     Class as provided herein, the Trustee shall (or shall request the
     Depository to) endorse on the schedule affixed to such Global Certificate
     (or on a continuation of such schedule affixed to such Global Certificate
     and made a part thereof) or otherwise make in its books and records an
     appropriate notation evidencing the date of such exchange or transfer and a
     decrease in the certificate balance of such Global Certificate equal to the
     certificate balance of such Individual Certificate issued in exchange
     therefor or upon transfer thereof.

     (g) The Securities Legend shall be placed on any Individual Certificate
issued in exchange for or upon transfer of another Individual Certificate or of
a beneficial interest in a Global Certificate.

     (h) Subject to the restrictions on transfer and exchange set forth in this
Section 5.02, the holder of any Individual Certificate may transfer or exchange
the same in whole or in part (in an initial certificate balance equal to the
minimum authorized denomination set forth in Section 5.01(h) above or any
integral multiple of $1.00 in excess thereof) by surrendering such Certificate
at the Corporate Trust Office, or at the office of any transfer agent, together
with an executed instrument of assignment and transfer satisfactory in form and
substance to the Trustee in the case of transfer and a written request for
exchange in the case of exchange. The holder of a beneficial interest in a
Global Certificate may, subject to the rules and procedures of the Depository,
cause the Depository (or its nominee) to notify the Trustee in writing of a
request for transfer or exchange of such beneficial interest for an Individual
Certificate or Certificates. Following a proper request for transfer or
exchange, the Trustee shall, within five Business Days of such request made at
such Corporate Trust Office, sign, countersign and deliver at such Corporate
Trust Office, to the transferee (in the case of transfer) or holder (in the case
of exchange) or send by first class mail at the risk of the transferee (in the
case of transfer) or holder (in the case of exchange) to such address as the
transferee or holder, as applicable, may request, an Individual Certificate or
Certificates, as the case may require, for a like aggregate Fractional Undivided
Interest and in such authorized denomination or denominations as may be
requested. The presentation for transfer or exchange of any Individual
Certificate shall not be valid unless made at the Corporate Trust Office by the
registered holder in person, or by a duly authorized attorney-in-fact.

     (i) At the option of the Certificateholders, Certificates may be exchanged
for other Certificates of authorized denominations of a like Class and aggregate
Fractional Undivided Interest, upon surrender of the Certificates to be
exchanged at any such office or agency; provided, however, that no Certificate
may be exchanged for new Certificates unless the original Fractional Undivided
Interest represented by each such new Certificate (i) is at least equal to the
minimum authorized denomination or (ii) is acceptable to the Seller as indicated
to the Trustee in writing. Whenever any Certificates are so surrendered for
exchange, the Trustee shall sign and countersign and the Trustee shall deliver
the Certificates which the Certificateholder making the exchange is entitled to
receive. In addition, with respect to each Class R Certificate, the holder
thereof may exchange, in the manner described above, such Class R Certificate
for four separate Certificates, each representing such holder's respective
fractional undivided interest in the Class R-IA Interest, the Class R-IB
Interest,

                                      -70-

<PAGE>

the Class R-II Interest and the Class R-III Interest, respectively, in each case
that was evidenced by the Class R Certificate being exchanged.

     (j) If the Trustee so requires, every Certificate presented or surrendered
for transfer or exchange shall be duly endorsed by, or be accompanied by a
written instrument of transfer, with a signature guarantee, in form satisfactory
to the Trustee, duly executed by the holder thereof or his or her attorney duly
authorized in writing.

     (k) No service charge shall be made for any transfer or exchange of
Certificates, but the Trustee may require payment of a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any
transfer or exchange of Certificates.

     (l) The Trustee shall cancel all Certificates surrendered for transfer or
exchange but shall retain such Certificates in accordance with its standard
retention policy or for such further time as is required by the record retention
requirements of the Securities Exchange Act of 1934, as amended, and thereafter
may destroy such Certificates.

     Section 5.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. (a) If (i)
any mutilated Certificate is surrendered to the Trustee, or the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (ii) there is delivered to the Trustee such security or
indemnity as it may require to save it harmless, and (iii) the Trustee has not
received notice that such Certificate has been acquired by a third Person, the
Trustee shall sign, countersign and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Fractional Undivided Interest but in each case bearing a different
number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Trustee and shall be of no further effect and evidence
no rights.

     (b) Upon the issuance of any new Certificate under this Section 5.03, the
Trustee may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute
complete and indefeasible evidence of ownership in the Trust Fund, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

     Section 5.04 PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate for registration of transfer, the Seller, the Trustee, the Guarantor
and any agent of the Seller or the Trustee may treat the Person in whose name
any Certificate is registered as the owner of such Certificate for the purpose
of receiving distributions pursuant to Section 6.01 and for all other purposes
whatsoever. Neither the Seller, the Trustee nor any agent of the Seller or the
Trustee shall be affected by notice to the contrary. No Certificate shall be
deemed duly presented for a transfer effective on any Record Date unless the
Certificate to be transferred is presented no later than the close of business
on the third Business Day preceding such Record Date.

     Section 5.05 TRANSFER RESTRICTIONS ON RESIDUAL CERTIFICATES. (a) Residual
Certificates, or interests therein, may not be transferred without the prior
express written consent of the Tax Matters Person and the Seller. As a
prerequisite to such consent, the proposed transferee must provide the Tax
Matters Person, the Seller and the Trustee with an affidavit that the proposed
transferee is a Permitted Transferee (and, unless the Tax Matters Person and the
Seller consent to the transfer to a person who is not a U.S. Person, an
affidavit that it is a U.S. Person) as provided in Subsection 5.05(b).

     (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee and the Seller an affidavit in the form attached
hereto as Exhibit E stating, among other things, that as of the date of such
transfer (i) such transferee is a Permitted Transferee and that (ii) such
transferee is not acquiring such Residual Certificate for the account of any
person who is not a Permitted Transferee. The Tax Matters Person shall not
consent to a transfer of a Residual Certificate if it has actual knowledge that
any statement made in the affidavit issued pursuant to the preceding sentence is
not true. Notwithstanding any transfer, sale or other disposition of a Residual
Certificate to any Person who is not a Permitted Transferee, such transfer, sale
or other disposition shall be deemed to be of no legal force or effect
whatsoever and such Person shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. None of the
Trustee, the Tax Matters Person or the Seller shall be under any liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 5.05(b) or for making payments due on such
Residual Certificate to the purported Holder thereof or taking any other action
with respect to such purported Holder under the provisions of this Agreement so
long as the written affidavit referred to above was received with respect to
such transfer, and the Tax Matters Person, the Trustee and the Seller, as
applicable, had no knowledge that it was untrue. The prior Holder shall be
entitled to recover from any purported Holder of a Residual Certificate that was
in fact not a permitted transferee under this Subsection 5.05(b) at the time it
became a Holder all payments made on such Residual Certificate. Each Holder of a
Residual Certificate, by acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this Subsection 5.05(b) and to any amendment
of this Agreement deemed necessary (whether as a result of new legislation or
otherwise) by counsel of the Tax Matters Person or the Seller to ensure that the
Residual Certificates are not transferred to any Person who is not a Permitted
Transferee and that any transfer of such Residual Certificates will not cause
the imposition of a tax upon the Trust or cause any REMIC to fail to qualify as
a REMIC.

     (c) Unless the Tax Matters Person shall have consented in writing (which
consent may be withheld in the Tax Matters Person's sole discretion), the
Residual Certificates (including a beneficial interest therein) may not be
purchased by or transferred to any person who is not a United States Person.

                                      -72-

<PAGE>

     (d) By accepting a Residual Certificate, the purchaser thereof agrees to be
a Tax Matters Person, and appoints the Trustee to act as its agent with respect
to all matters concerning the tax obligations of the Trust.

     Section 5.06 RESTRICTIONS ON TRANSFERABILITY OF CERTIFICATES. (a) No offer,
sale, transfer or other disposition (including pledge) of any Certificate shall
be made by any Holder thereof unless registered under the Securities Act, or an
exemption from the registration requirements of the Securities Act and any
applicable state securities or "Blue Sky" laws is available and the prospective
transferee (other than the Seller) of such Certificate signs and delivers to the
Trustee an Investment Letter, if the transferee is an Institutional Accredited
Investor, in the form set forth as Exhibit F-l hereto, or a Rule 144A
Certificate, if the transferee is a QIB, in the form set forth as Exhibit F-2
hereto. Notwithstanding the provisions of the immediately preceding sentence, no
restrictions shall apply with respect to the transfer or registration of
transfer of a beneficial interest in any Certificate that is a Global
Certificate of a Class to a transferee that takes delivery in the form of a
beneficial interest in the Global Certificate of such Class provided that each
such transferee shall be deemed to have made such representations and warranties
contained in the Rule 144A Certificate as are sufficient to establish that it is
a QIB. In the case of a proposed transfer of any Certificate to a transferee
other than a QIB, the Trustee may require an Opinion of Counsel that such
transaction is exempt from the registration requirements of the Securities Act.
The cost of such opinion shall not be an expense of the Trustee or the Trust
Fund.

     (b) The Private Certificates shall each bear a Securities Legend.

     Section 5.07 ERISA RESTRICTIONS. (a) Subject to the provisions of
subsection (b), no Residual Certificates or Private Certificates may be acquired
directly or indirectly by, or on behalf of, an employee benefit plan or other
retirement arrangement which is subject to Title I of ERISA and/or Section 4975
of the Code, unless the proposed transferee provides either (i) the Master
Servicer and the Trustee with an Opinion of Counsel satisfactory to the Master
Servicer and the Trustee, which opinion will not be at the expense of the Master
Servicer, that the purchase of such Certificates by or on behalf of such Plan is
permissible under applicable law, will not constitute or result in a nonexempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Trustee or the Master Servicer to any obligation in addition to
those undertaken in the Agreement or (ii) in the case of the Class B-4, Class
B-5 and Class B-6 Certificates, a representation or certification to the Trustee
(upon which the Trustee is authorized to rely) to the effect that the proposed
transfer and/or holding of such a Certificate and the servicing, management and
operation of the Trust: (I) will not result in a prohibited transaction under
Section 406 of ERISA or Section 4975 of the Code which is not covered under an
individual or class prohibited transaction exemption including but not limited
to Department of Labor Prohibited Transaction Exemption ("PTE") 84-14 (Class
Exemption for Plan Asset Transactions Determined by Independent Qualified
Professional Asset Managers); PTE 91-38 (Class Exemption for Certain
Transactions Involving Bank Collective Investment Funds); PTE 90-1 (Class
Exemption for Certain Transactions Involving Insurance Company Pooled Separate
Accounts), PTE 95-60 (Class Exemption for Certain Transactions Involving
Insurance Company General Accounts), and PTCE 96-23 (Class Exemption for Plan
Asset Transactions Determined by In-House Asset Managers and (II) will not
subject the Seller, the Master Servicer or the Trustee to any obligation in
addition to those undertaken in the Agreement.

                                      -73-

<PAGE>

     (b) Any Person acquiring an interest in a Global Certificate which is a
Private Certificate, by acquisition of such Certificate, shall be deemed to have
represented to the Trustee that in the case of the Class B-4, Class B-5 and
Class B-6 Certificates, either: (i) it is not acquiring an interest in such
Certificate directly or indirectly by, or on behalf of, an employee benefit plan
or other retirement arrangement which is subject to Title I of ERISA and/or
Section 4975 of the Code, or (ii) the transfer and/or holding of an interest in
such Certificate to that Person and the subsequent servicing, management and/or
operation of the Trust and its assets: (I) will not result in any prohibited
transaction which is not covered under an individual or class prohibited
transaction exemption, including, but not limited to, PTE 84-14, PTE 91-38, PTE
90-1, PTE 95-60 or PTE 96-23 and (II) will not subject the Seller, the Master
Servicer or the Trustee to any obligation in addition to those undertaken in the
Agreement.

     (c) Neither the Trustee nor the Master Servicer will be required to
monitor, determine or inquire as to compliance with the transfer restrictions
with respect to the Global Certificates. Any attempted or purported transfer of
any Certificate in violation of the provisions of Subsections (a) or (b) above
shall be void ab initio and such Certificate shall be considered to have been
held continuously by the prior permitted Certificateholder. Any transferor of
any Certificate in violation of such provisions, shall indemnify and hold
harmless the Trustee and the Master Servicer from and against any and all
liabilities, claims, costs or expenses incurred by the Trustee or the Master
Servicer as a result of such attempted or purported transfer. The Trustee shall
have no liability for transfer of any such Global Certificates in or through
book-entry facilities of any Depository or between or among Depository
Participants or Certificate Owners made in violation of the transfer
restrictions set forth herein.

     Section 5.08 RULE 144A INFORMATION. For so long as any Certificates are
outstanding and are "restricted securities" within the meaning of Rule 144(a)(3)
of the Securities Act, (1) the Seller will provide or cause to be provided to
any holder of such Certificates and any prospective purchaser thereof designated
by such a holder, upon the request of such holder or prospective purchaser, the
information required to be provided to such holder or prospective purchaser by
Rule 144A(d)(4) under the Securities Act; and (2) the Seller shall update such
information from time to time in order to prevent such information from becoming
false and misleading and will take such other actions as are necessary to ensure
that the safe harbor exemption from the registration requirements of the
Securities Act under Rule 144A is and will be available for resales of such
Certificates conducted in accordance with Rule 144A.

          distributions in paragraphs (A), (B) and (C) above will be distributed
          to the Group 1, Group 2 and Group 3 Senior Certificates, to the extent

          to the Group 1 Senior Certificates pursuant to clauses SECOND, THIRD
          and FOURTH of paragraph (A), to the Group 2 Senior Certificates
          pursuant to clauses SECOND, THIRD and FOURTH of paragraph (B), and to

          (E) Except as provided in paragraphs (F) and (G) below, on each
          Distribution Date prior to the Cross-Over Date, an amount equal to any
          remaining Group 1, Group 2 and Group 3 Available Funds after the
          distributions in paragraphs (A), (B) and (C) above will be distributed
          sequentially, in the following order, to the Class B-1, Class B-2,

          the reduction of the Current Principal Amount of the Group 1, Group 2
          or Group 3 Senior Certificates to zero, the remaining Class or Classes

<PAGE>

          upon their Current Principal Amounts immediately prior to such
          Distribution Date, in addition to any Principal Prepayments related to
          such remaining Senior Certificates' respective Loan Group allocated to
          such Group of Senior Certificates, 100% of the Principal Prepayments
          on any Mortgage Loan in the Loan Group relating to the fully repaid
          Class of Senior Certificates, first to the Group 1 and Group 2 Senior
          Certificates pro rata based upon their Current Principal Amounts
          immediately prior to such Distribution Date, and then to the Group 3
          Senior Certificates; provided, however, that if (i) the weighted
          average Subordinate Percentage equals or exceeds 7.00% on such
          Distribution Date and (ii) the aggregate Scheduled Principal Balance
          of the Mortgage Loans delinquent 60 days or more (including for this
          purpose any such Mortgage Loans in foreclosure and Mortgage Loans with
          respect to which the related Mortgaged Property has been acquired by
          the Trust), averaged over the last six months, as a percentage of the
          sum of the aggregate Current Principal Amount of the Subordinate
          Certificates does not exceed 100%, then the additional allocation of
          Principal Prepayments to the Senior Certificates in accordance with
          this paragraph (F) will not be made.

          (G) If on any Distribution Date on which the aggregate Current
          Principal Amount of any Class or Classes of Senior Certificates would
          be greater than the aggregate Scheduled Principal Balance of the
          Mortgage Loans in its related Loan Group and any Subordinate
          Certificates are still outstanding in each case after giving effect to
          distributions to be made on such Distribution Date, (i) 100% of
          amounts otherwise allocable to the Subordinate Certificates in respect
          of principal will be distributed to such Class or Classes of Senior
          Certificates in reduction of the Current Principal Amounts thereof,
          until the aggregate Current Principal Amount of such Class or Classes
          of Senior Certificates is an amount equal to the aggregate Scheduled
          Principal Balance of the Mortgage Loans in its related Loan Group, and
          (ii) the Accrued Certificate Interest otherwise allocable to the
          Subordinate Certificates on such Distribution Date will be reduced, if
          necessary, and distributed to such Class or Classes of Senior
          Certificates in an amount equal to the Accrued Certificate Interest
          for such Distribution Date on the excess of (x) the aggregate Current
          Principal Balance of such Class or Classes of Senior Certificates over
          (y) the aggregate Scheduled Principal Balance of the Mortgage Loans in
          the related Loan Group. Any such reduction in the Accrued Certificate
          Interest on the Subordinate Certificates will be allocated in reverse
          order of the Subordinate Certificates numerical designations,
          commencing with the Class B-6 Certificates.

          (H) If, on any Distribution Date, (i) the Guarantor exercises its
          option to purchase the Group 1 and Group 2 Mortgage Loans pursuant to
          Section 10.01, and (ii) distributing the proceeds from such purchase
          to the remaining Certificates as set forth above in paragraph (E)
          would result in the aggregate Current Principal Amount of the
          outstanding Subordinate Certificates being less than 7.00% of their
          initial Current Principal Amount, then such amount otherwise payable
          to the Subordinate Certificates will be distributed, first to the
          Class III-A Certificates, and then to the remaining Subordinate
          Certificates, on a pro rata basis, in each case in reduction of

                                      -77-

<PAGE>

          the Current Principal Amount, until the Current Principal Amount of
          such Class or Classes of Certificates have been reduced to zero.

     (b) If, after distributions have been made pursuant to priorities FIRST,
SECOND and THIRD of clauses (a)(i)(A) and (B) and priorities FIRST and SECOND of
clause (a)(i)(C) above on any Distribution Date, the remaining Group 1, Group 2
or Group 3 Available Funds are less than the sum of the Group 1, Group 2 or
Group 3 Senior Optimal Principal Amounts such amount shall be reduced, and such
remaining funds will be distributed on the related Senior Certificates on the
basis of such reduced amount.

     (c) "Pro rata" distributions among Classes of Certificates will be made in
proportion to the then Current Principal Amount of such Classes.

     (d) On each Distribution Date, any Available Funds remaining after payment
of interest and principal to the Classes of Certificates entitled thereto, as
described above, will be distributed to the Class R Certificates; provided that
if on any Distribution Date there are any Group 1, Group 2 or Group 3 Available
Funds remaining after payment of interest and principal to a Class or Classes of
Certificates entitled thereto, such amounts will be distributed, first to the
Group 1 and Group 2 Senior Certificates pro rata based upon their Current
Principal Amounts immediately prior to such Distribution Date, and then to the
Group 3 Senior Certificates, until all amounts due to all Classes of Senior
Certificates have been paid in full, before any amounts are distributed to the
Class R Certificates.

     (e) No Accrued Certificate Interest will be payable with respect to any
Class of Certificates after the Distribution Date on which the Current Principal
Amount of such Certificate has been reduced to zero.

     (f) If on any Distribution Date the Available Funds for the Senior
Certificates in any Certificate Group is less than the Accrued Certificate
Interest on the related Senior Certificates for such Distribution Date prior to
reduction for Net Interest Shortfall and the interest portion of Realized
Losses, the shortfall will be allocated among the holders of each Class of
Senior Certificates in such Certificate Group in proportion to the respective
amounts of Accrued Certificate Interest that would have been allocated thereto
in the absence of such Net Interest Shortfall and/or Realized Losses for such
Distribution Date. In addition, the amount of any interest shortfalls will
constitute unpaid Accrued Certificate Interest and will be distributable to
holders of the Certificates of the related Classes entitled to such amounts on
subsequent Distribution Dates, to the extent of the applicable Available Funds
after current interest distributions as required herein. Any such amounts so
carried forward will not bear interest. Shortfalls in interest payments will not
be offset by a reduction in the servicing compensation of the Master Servicer or
otherwise, except to the extent of applicable Compensating Interest Payments.

     (g) On each Distribution Date, the aggregate amount of Deferred Interest,
if any, that is added to the principal balance of the Mortgage Loans on the Due
Date occurring in the month in which such Distribution Date occurs will be
allocated to each class of Certificates as an Interest Shortfall as described in
clause (g) above, on a pro rata basis based on a fraction, the numerator of
which is the Current Principal Amount of each such class and the denominator of
which is the

                                      -78-

<PAGE>

aggregate Current Principal Amount of such Classes of Certificates, in each case
immediately prior to such Distribution Date. Deferred Interest allocated to any
Certificate on any Distribution Date will be added to the Current Principal
Amount thereof on such Distribution Date and will thereafter bear interest at
the then applicable adjustable Pass-Through Rate.

     (h) The expenses and fees of the Trust shall be paid by each of the REMICs,
to the extent that such expenses relate to the assets of each of such respective
REMICs, and all other expenses and fees of the Trust shall be paid pro rata by
each of the REMICs.

     Section 6.02 ALLOCATION OF LOSSES. (a) On or prior to each Determination
Date, the Master Servicer shall determine the amount of any Realized Loss in
respect of each Mortgage Loan that occurred during the immediately preceding
calendar month.

     (b) With respect to any Certificates on any Distribution Date, the
principal portion of each Realized Loss on a Mortgage Loan shall be allocated as
follows:

          FIRST, to the Class B-6 Certificates until the Current Principal
     Amount thereof has been reduced to zero;

          SECOND, to the Class B-5 Certificates until the Current Principal
     Amount thereof has been reduced to zero;

          THIRD, to the Class B-4 Certificates until the Current Principal
     Amount thereof has been reduced to zero;

          FOURTH, to the Class B-3 Certificates until the Current Principal
     Amount thereof has been reduced to zero;

          FIFTH, to the Class B-2 Certificates until the Current Principal
     Amount thereof has been reduced to zero;

          SIXTH, to the Class B-1 Certificates until the Current Principal
     Amount thereof has been reduced to zero; and

          SEVENTH, to the Senior Certificates as follows:

               (i) FIRST, if the Realized Loss occurs on a Mortgage Loan in a
          Mortgage Loan Group where the aggregate Stated Principal Balance of
          the Mortgage Loans in such Mortgage Loan Group is greater than the
          aggregate Current Principal Amount of the related Senior Certificates,
          the Realized Loss will be allocated to any Senior Certificates related
          to a Mortgage Loan Group where the aggregate Stated Principal Balance
          of the Mortgage Loans in such Mortgage Loan Group is less than the
          aggregate Current Principal Amount of the related Senior Certificates
          (any such amount, the "Group Deficiency Amount"), pro rata, based on
          the respective Group Deficiency Amount, in each case until the amount
          by which the aggregate Stated Principal Balance of the Mortgage Loans
          in the Mortgage Loan Group in which the

                                      -79-

<PAGE>

          Realized Loss occurs exceeds the aggregate Current Principal Amount of
          the related Senior Certificates has been reduced to zero; and

               (ii) SECOND, to the Senior Certificates related to the Mortgage
          Loan Group in which the Realized Loss occurred, until the Current
          Principal Amount thereof has been reduced to zero. if such loss is on
          a Group 1, Group 2 or Group 3 Mortgage Loan, to the Group 1, Group 2
          and Group 3 Senior Certificates, respectively, on a pro rata basis.

     (c) Notwithstanding the foregoing clause (b), no such allocation of any
Realized Loss shall be made on a Distribution Date to any Class of Certificates
to the extent that such allocation would result in the reduction of the
aggregate Current Principal Amounts of all the Certificates as of such
Distribution Date, after giving effect to all distributions and prior
allocations of Realized Losses on such date, to an amount less than the
aggregate Scheduled Principal Balance of all of the Mortgage Loans as of the
first day of the month of such Distribution Date (such limitation, the "Loss
Allocation Limitation").

     (d) Any Realized Losses allocated to a Class of Certificates shall be
allocated among the Certificates of such Class in proportion to their respective
Current Principal Amounts. Any allocation of Realized Losses shall be
accomplished by reducing the Current Principal Amount of the related
Certificates on the related Distribution Date.

     (e) Realized Losses shall be allocated on the Distribution Date in the
month following the month in which such loss was incurred and, in the case of
the principal portion thereof, after giving effect to distributions made on such
Distribution Date.

     (f) On each Distribution Date, the Trustee shall determine the Subordinate
Certificate Writedown Amount. Any such Subordinate Certificate Writedown Amount
shall effect a corresponding reduction in the Current Principal Amount of (i) if
prior to the Cross-Over Date, the Current Principal Amounts of the Subordinate
Certificates, in the reverse order of their numerical Class designations and
(ii) from and after the Cross-Over Date, the Senior Certificates which reduction
shall occur on such Distribution Date after giving effect to distributions made
on such Distribution Date.

     (g) Any Net Interest Shortfall will be allocated among the Classes of
Certificates in proportion to the respective amounts of Accrued Certificate
Interest that would have been allocated thereto in the absence of such Net
Interest Shortfall for such Distribution Date. The interest portion of any
Realized Losses with respect to the Mortgage Loans occurring on or prior to the
Cross-Over Date will not be allocated among any Certificates, but will reduce
the amount of Available Funds on the related Distribution Date. As a result of
the subordination of the Subordinate Certificates in right of distribution, such
Realized Losses will be borne by the Subordinate Certificates in inverse order
of their numerical Class designations. Following the Cross-Over Date, the
interest portion of Realized Losses on the Mortgage Loans in any Loan Group will
be allocated to the related Senior Certificates.

                                      -83-

<PAGE>

Trustee shall have the right to change the way such reports are distributed in
order to make such distribution more convenient and/or more accessible to the
parties, and the Trustee shall provide timely and adequate notification to all
parties regarding any such change.

     On the third Business Day preceding each Distribution Date, the Trustee

sentence) a statement identifying the Class Factor for each Class of
Certificates. The Trustee shall deliver such statement on or before 12:00 noon
(New York time) on such day via the internet using the following domain name:
bond_admin@fanniemae.com. If a Guarantor Payment will be payable on a
Distribution Date, all information required under Section 6.04 must also be
similarly delivered to Guarantor on such third Business Day proceeding such
Distribution Date. The second consecutive failure by the Trustee to deliver the
Class Factor (or to deliver an accurate Class Factor) to the Guarantor shall
constitute an event of default and permit the Guarantor to remove the Trustee
for cause; provided that the Master Servicer had delivered the information set
forth above for the related Distribution Date to the Trustee.

     (b) By April 30 of each year beginning in 2003, the Trustee will furnish

substantially comparable information shall be provided by the Trustee pursuant
to the requirements of the Code.

     Section 6.05 MONTHLY ADVANCES. The Master Servicer shall, or shall cause
the related subservicer pursuant to the Subservicing Agreement to, make an
Advance and deposit such Advance in the Protected Account. Each such Advance
shall be remitted to the Distribution Account no later than 1:00 p.m. Eastern
time on the Distribution Account Deposit Date in immediately available funds.
The Master Servicer shall be obligated to make any such Advance only to the
extent that such advance would not be a Nonrecoverable Advance. If the Master
Servicer shall have determined that it has made a Nonrecoverable Advance or that
a proposed Advance or a lesser portion of such Advance would constitute a
Nonrecoverable Advance, the Master Servicer shall deliver (i) to the Trustee for
the benefit of the Certificateholders funds constituting the remaining portion
of such Advance, if applicable, and (ii) to the Seller, each Rating Agency and
the Trustee an Officer's Certificate setting forth the basis for such
determination. Subject to the Master Servicer's recoverability determination, in
the event that a subservicer fails to make a required Advance, the Master
Servicer shall be required to remit the amount of such Advance to the
Distribution Account.

          In lieu of making all or a portion of such Advance from its own funds,
the Master Servicer may (i) cause to be made an appropriate entry in its records
relating to the Protected Account that any Amount Held for Future Distributions
has been used by the Master Servicer in discharge of its obligation to make any
such Advance and (ii) transfer such funds from the Protected Account to the
Distribution Account. Any funds so applied and transferred shall be replaced by
the Master Servicer by deposit in the Distribution Account, no later than the
close of business on the

                                      -84-

<PAGE>

Business Day immediately preceding the Distribution Date on which such funds are
required to be distributed pursuant to this Agreement.

          The Master Servicer shall be entitled to be reimbursed from the
Distribution Account for all Advances of its own funds made pursuant to this
Section as provided in Section 4.02. The obligation to make Advances with
respect to any Mortgage Loan shall continue until such Mortgage Loan is paid in
full or the related Mortgaged Property or related REO Property has been
liquidated or until the purchase or repurchase thereof (or substitution
therefor) from the Trust Fund pursuant to any applicable provision of this
Agreement, except as otherwise provided in this Section 6.05.

          Subject to and in accordance with the provisions of Article VIII
hereof, in the event the Master Servicer fails to make such Advance, then the
Trustee, as Successor Master Servicer, shall be obligated to make such Advance,
subject to the provisions of this Section 6.05.

     Section 6.06 COMPENSATING INTEREST PAYMENTS. In the event that there is a
Prepayment Interest Shortfall arising from a voluntary Principal Prepayment in
full or in part by the Mortgagor with respect to any Mortgage Loan, the Master
Servicer shall, to the extent of the Servicing Fee for such Distribution Date,
deposit into the Distribution Account, as a reduction of the Servicing Fee for
such Distribution Date, no later than the close of business on the Business Day
immediately preceding such Distribution Date, an amount equal to the Prepayment
Interest Shortfall; and in case of such deposit, the Master Servicer shall not
be entitled to any recovery or reimbursement from the Seller, the Trustee, the
Seller, the Trust Fund or the Certificateholders.

          The Master Servicer and the Seller shall each be liable in accordance
herewith only to the extent of the obligations specifically and respectively
imposed upon and undertaken by them herein.

          Section 7.02 MERGER OR CONSOLIDATION OF THE MASTER SERVICER OR THE
                       SELLER.

          The Master Servicer and the Seller will each keep in full effect its
existence, rights and franchises as a corporation under the laws of the United
States or under the laws of one of the States thereof and will each obtain and
preserve its qualification to do business as a foreign corporation in each
jurisdiction in which such qualification is or shall be necessary to protect the
validity and enforceability of this Agreement, or any of the Mortgage Loans and
to perform its respective duties under this Agreement.

          Any Person into which the Master Servicer or the Seller may be merged
or consolidated, or any Person resulting from any merger or consolidation to
which the Master Servicer or the Seller shall be a party, or any person
succeeding to the business of the Master Servicer or the Seller, shall be the
successor of the Master Servicer or the Seller, as the case may be, hereunder,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding;
provided that the successor or surviving Person to the Master Servicer shall be
qualified to sell mortgage loans to, and to service mortgage loans on behalf of,
Fannie Mae or Freddie Mac.

          Section 7.03 LIMITATION ON LIABILITY OF THE SELLER, THE GUARANTOR, THE
                       MASTER SERVICER AND OTHERS.

          None of the Seller, the Guarantor, the Master Servicer or any of the

Master Servicer shall be under any liability to the Trust Fund or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement, or for errors in judgment;
provided that this provision shall not protect the Seller, the Guarantor, the
Master Servicer or any such Person against any breach of representations or
warranties made by it herein or protect the Seller, the Guarantor, the Master
Servicer or any such Person from any liability that would otherwise be imposed
by reasons of willful misfeasance, bad faith or gross negligence in the
performance of duties or by reason of reckless disregard of obligations and
duties hereunder. The Seller, the Guarantor, the Master Servicer and any
director, officer, employee or agent of the Seller, the Guarantor or the Master
Servicer may rely in good faith on any document of any kind prima facie properly
executed and submitted by any Person respecting any matters arising hereunder.
The Seller, the Guarantor, the Master Servicer and any director, officer,
employee or agent of the Seller, the Guarantor or the Master Servicer shall be
indemnified by the Trust Fund and held harmless against any loss, liability or
expense incurred in connection with any audit, controversy or judicial
proceeding relating to a governmental taxing

Master Servicer shall be under any obligation to appear in, prosecute or defend
any legal action that is not incidental to its respective duties hereunder and
that in its opinion may involve it in any expense or liability; provided that
any of the Seller, the Guarantor or the Master Servicer may, in its discretion
undertake any such action that it may deem necessary or desirable in respect of
this Agreement and the rights and duties of the parties hereto and interests of
the Trustee and the Certificateholders hereunder. In such event, the legal
expenses and costs of such action and any liability resulting therefrom shall
be, expenses, costs and liabilities of the Trust Fund, and the Seller, the
Guarantor and the Master Servicer shall be entitled to be reimbursed therefor
out of the Protected Account as provided by Section 4.02 and out of the
Distribution Account as provided in Section 4.05 hereof.

     Section 7.04 LIMITATION ON RESIGNATION OF MASTER SERVICER.

          The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except upon (x) determination that its duties hereunder are
no longer permissible under applicable law or (y) compliance with the following
requirements: (i) the Master Servicer has proposed a successor to the Trustee
and the Trustee has consented thereto (such consent not to be withheld
unreasonably); (ii) the successor is qualified to sell mortgage loans to, and to
service mortgage loans on behalf of, Fannie Mae or Freddie Mac; and (iii) each
Rating Agency shall have delivered to the Trustee written confirmation that the
appointment of such successor will not result in the qualification, reduction or
withdrawal of the then-current ratings assigned by such Rating Agency to any of
the Certificates. Any such determination permitting the resignation of the
Master Servicer shall be evidenced by an Opinion of Counsel (which opinion shall
not be an expense of the Trustee) to such effect delivered to the Trustee. No
such resignation shall become effective until the Trustee or a successor
servicer to such appointment shall have assumed the Master Servicer's
responsibilities, duties, liabilities and obligations hereunder.

     Section 7.05 ERRORS AND OMISSIONS INSURANCE; FIDELITY BONDS.

          The Master Servicer shall obtain and maintain in force (a) a policy or
policies of insurance covering errors and omissions in the performance of its
obligations as successor servicer thereunder, and (b) a fidelity bond in respect
of its officers, employees and agents. Each such policy or policies and bond
shall, together, comply with the requirements from time to time of Fannie Mae
for persons performing servicing for mortgage loans purchased by Fannie Mae. In
the event that any such policy or bond ceases to be in effect, the Master
Servicer shall use its reasonable best efforts to obtain a comparable
replacement policy or bond from an insurer or issuer, meeting the requirements
set forth above as of the date of such replacement.

                                     Default

     Section 8.01 EVENTS OF DEFAULT. "Event of Default," wherever used herein,
means any one of the following events (whatever the reason for such Event of
Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or
any order, rule or regulation of any administrative or governmental body) and
only with respect to the defaulting Master Servicer:

          (i) The Master Servicer fails to cause to be deposited in the
     Distribution Account any amount so required to be deposited pursuant to
     this Agreement, and such failure continues unremedied for a period of three
     Business Days after the date upon which written notice of such failure,
     requiring the same to be remedied, shall have been given to the Master
     Servicer; or

          (ii) The Master Servicer fails to observe or perform in any material
     respect any other material covenants and agreements set forth in this
     Agreement to be performed by it, which covenants and agreements materially
     affect the rights of Certificateholders, and such failure continues
     unremedied for a period of 60 days after the date on which written notice
     of such failure, properly requiring the same to be remedied, shall have
     been given to the Master Servicer by the Trustee or to the Master Servicer
     and the Trustee by the Guarantor or by the Holders of Certificates
     evidencing Fractional Undivided Interests aggregating not less than 25% of
     the Trust Fund; or

          (iii) There is entered against the Master Servicer a decree or order
     by a court or agency or supervisory authority having jurisdiction in the
     premises for the appointment of a conservator, receiver or liquidator in
     any insolvency, readjustment of debt, marshaling of assets and liabilities
     or similar proceedings, or for the winding up or liquidation of its
     affairs, and the continuance of any such decree or order is unstayed and in
     effect for a period of 60 consecutive days, or an involuntary case is
     commenced against the Master Servicer under any applicable insolvency or
     reorganization statute and the petition is not dismissed within 60 days
     after the commencement of the case; or

          (iv) The Master Servicer consents to the appointment of a conservator
     or receiver or liquidator in any insolvency, readjustment of debt,
     marshaling of assets and liabilities or similar proceedings of or relating
     to the Master Servicer or substantially all of its property; or the Master
     Servicer admits in writing its inability to pay its debts generally as they
     become due, files a petition to take advantage of any applicable insolvency
     or reorganization statute, makes an assignment for the benefit of its
     creditors, or voluntarily suspends payment of its obligations; or

          (v) The Master Servicer assigns or delegates its duties or rights
     under this Agreement in contravention of the provisions permitting such
     assignment or delegation under Sections 7.05 or 7.07; or

                                      -88-

<PAGE>

     (vi) The Master Servicer ceases to be an approved servicer of Fannie Mae.

In each and every such case, so long as such Event of Default with respect to
the Master Servicer shall not have been remedied, either the Trustee, at the
direction of the Guarantor, or the Holders of Certificates evidencing Fractional
Undivided Interests aggregating not less than 51% of the principal of the Trust
Fund, by notice in writing to the Master Servicer (and to the Trustee if given
by such Certificateholders), with a copy to the Rating Agencies, may terminate
all of the rights and obligations (but not the liabilities) of the Master
Servicer under this Agreement and in and to the Mortgage Loans and/or the REO
Property serviced by the Master Servicer and the proceeds thereof. Upon the
receipt by the Master Servicer of the written notice, all authority and power of
the Master Servicer under this Agreement, whether with respect to the
Certificates, the Mortgage Loans, REO Property or under any other related
agreements (but only to the extent that such other agreements relate to the
Mortgage Loans or related REO Property) shall, subject to Section 8.02,
automatically and without further action pass to and be vested in the Trustee
pursuant to this Section 8.01; and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer as attorney-in-fact or otherwise, any and all documents and other
instruments and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Mortgage Loans and
related documents, or otherwise. The Master Servicer agrees to cooperate with
the Trustee in effecting the termination of the Master Servicer's rights and
obligations hereunder, including, without limitation, the transfer to the
Trustee of (i) the property and amounts which are then or should be part of the
Trust or which thereafter become part of the Trust; and (ii) originals or copies
of all documents of the Master Servicer reasonably requested by the Trustee to
enable it to assume the Master Servicer's duties thereunder. In addition to any
other amounts which are then, or, notwithstanding the termination of its
activities under this Agreement, may become payable to the Master Servicer under
this Agreement, the Master Servicer shall be entitled to receive, out of any
amount received on account of a Mortgage Loan or related REO Property, that
portion of such payments which it would have received as reimbursement under
this Agreement if notice of termination had not been given. The termination of
the rights and obligations of the Master Servicer shall not affect any
obligations incurred by the Master Servicer prior to such termination.

     Section 8.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) Upon the receipt
by the Master Servicer of a notice of termination pursuant to Section 8.01 or an
Opinion of Independent Counsel pursuant to Section 7.05 to the effect that the
Master Servicer is legally unable to act or to delegate its duties to a Person
which is legally able to act, or at the request of the Guarantor, the Trustee
shall automatically become the successor in all respects to the Master Servicer
in its capacity under this Agreement and the transactions set forth or provided
for herein and shall thereafter be subject to all the responsibilities, duties,
liabilities and limitations on liabilities relating thereto placed on the Master
Servicer by the terms and provisions hereof; provided, however, that EMC shall
have the right to either (a) immediately assume the duties of the Master
Servicer or (b) select a successor Master Servicer acceptable to the Guarantor;
provided further, however, that the Trustee shall have no obligation whatsoever
with respect to any liability (other than advances deemed recoverable and not
previously made) incurred by the Master Servicer at or prior to the time of
termination. Notwithstanding the foregoing, the parties hereto agree that the
Trustee, in its capacity as Successor Master Servicer, immediately will assume
all of the obligations of the Master Servicer to make Monthly Advances and the
Trustee will assume the other duties of the Master Servicer as soon as

                                      -89-

<PAGE>

practicable, but in no event later than 90 days after the Trustee becomes
Successor Master Servicer pursuant to the preceding sentence. Notwithstanding
the foregoing, the Trustee, in its capacity as Successor Master Servicer, shall
not be responsible for the lack of information and/or documents that it cannot
obtain through reasonable efforts. As compensation therefor, but subject to
Section 7.06, the Trustee shall be entitled to all funds relating to the
Mortgage Loans which the Master Servicer would have been entitled to retain if
the Master Servicer had continued to act hereunder, except for those amounts due
the Master Servicer as reimbursement permitted under this Agreement for advances
previously made or expenses previously incurred. Notwithstanding the above, the
Trustee may, if it shall be unwilling so to act, or shall, if it is legally
unable so to act, or at the request of the Guarantor, appoint or petition a
court of competent jurisdiction to appoint, any established housing and home
finance institution which is a Fannie Mae- or Freddie Mac-approved servicer
acceptable to the Guarantor, and with respect to a successor to the Master
Servicer only, having a net worth of not less than $10,000,000, as the successor
to the Master Servicer hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of the Master Servicer hereunder;
provided, that the Trustee shall obtain a letter from each Rating Agency that
the ratings, if any, on each of the Certificates will not be lowered as a result
of the selection of the successor to the Master Servicer. Pending appointment of
a successor to the Master Servicer hereunder, the Trustee shall act in such
capacity as hereinabove provided. In connection with such appointment and
assumption, the Trustee may make such arrangements for the compensation of such
successor out of payments on the Mortgage Loans as it and such successor shall
agree; provided, however, that the provisions of Section 7.06 shall apply, no
such compensation shall be in excess of that permitted the Trustee under this
Subsection 8.02(a), and that such successor shall undertake and assume the
obligations of the Trustee to pay compensation to any third Person acting as an
agent or independent contractor in the performance of master servicing
responsibilities hereunder. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

     (b) If the Trustee shall succeed to any duties of the Master Servicer
respecting the Mortgage Loans as provided herein, it shall do so in a separate
capacity and not in its capacity as Trustee and, accordingly, the provisions of
Article IX shall be inapplicable to the Trustee in its duties as the successor
to the Master Servicer in the servicing of the Mortgage Loans (although such
provisions shall continue to apply to the Trustee in its capacity as Trustee);
the provisions of Article VII, however, shall apply to it in its capacity as
successor master servicer.

     Section 8.03 NOTIFICATION TO CERTIFICATEHOLDERS. Upon any termination or
appointment of a successor to the Master Servicer, the Trustee shall give prompt
written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register and to the Rating Agencies.

     Section 8.04 WAIVER OF DEFAULTS. The Trustee shall transmit by mail to all
Certificateholders, within 60 days after the occurrence of any Event of Default
known to the Trustee, unless such Event of Default shall have been cured, notice
of each such Event of Default hereunder known to the Trustee. The Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
51% of the Trust Fund may, on behalf of all Certificateholders, waive any
default by the Master Servicer in the performance of its obligations hereunder
and the consequences thereof, except a default in the making of or the causing
to be made any required distribution on the

                                      -90-

<PAGE>

Certificates. Upon any such waiver of a past default, such default shall be
deemed to cease to exist, and any Event of Default arising therefrom shall be
deemed to have been timely remedied for every purpose of this Agreement. No such
waiver shall extend to any subsequent or other default or impair any right
consequent thereon except to the extent expressly so waived. The Trustee shall
give notice of any such waiver to the Rating Agencies.

     Section 8.05 LIST OF CERTIFICATEHOLDERS. Upon written request of three or
more Certificateholders of record, for purposes of communicating with other
Certificateholders with respect to their rights under this Agreement, the
Trustee will afford such Certificateholders access during business hours to the
most recent list of Certificateholders held by the Trustee.

                                      -91-

                                   ARTICLE IX

                             Concerning the Trustee

     Section 9.01 DUTIES OF TRUSTEE. (a) The Trustee, prior to the occurrence of
an Event of Default and after the curing or waiver of all Events of Default
which may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Agreement as duties of the Trustee. If an
Event of Default has occurred and has not been cured or waived, the Trustee
shall exercise such of the rights and powers vested in it by this Agreement, and
subject to Section 8.02(b) use the same degree of care and skill in their
exercise, as a prudent person would exercise under the circumstances in the
conduct of his own affairs.

     (b) Upon receipt of all resolutions, certificates, statements, opinions,
reports, documents, orders or other instruments which are specifically required
to be furnished to the Trustee pursuant to any provision of this Agreement, the
Trustee shall examine them to determine whether they are in the form required by
this Agreement; provided, however, that the Trustee shall not be responsible for
the accuracy or content of any resolution, certificate, statement, opinion,
report, document, order or other instrument furnished by the Master Servicer;
provided, further, that the Trustee shall not be responsible for the accuracy or
verification of any calculation provided to it pursuant to this Agreement.

     (c) On each Distribution Date, the Trustee shall make monthly distributions
and the final distribution to the Certificateholders from funds in the
Distribution Account as provided in Sections 6.01 and 10.01 herein.

     (d) No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct; provided, however, that:

          (i) Prior to the occurrence of an Event of Default, and after the
     curing or waiver of all such Events of Default which may have occurred, the
     duties and obligations of the Trustee shall be determined solely by the
     express provisions of this Agreement, the Trustee shall not be liable
     except for the performance of their respective duties and obligations as
     are specifically set forth in this Agreement, no implied covenants or
     obligations shall be read into this Agreement against the Trustee and, in
     the absence of bad faith on the part of the Trustee, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon any certificates or opinions furnished
     to the Trustee and conforming to the requirements of this Agreement;

          (ii) The Trustee shall not be liable in its individual capacity for an
     error of judgment made in good faith by a Responsible Officer or
     Responsible Officers of the Trustee unless it shall be proved that the
     Trustee was negligent in ascertaining the pertinent facts;

          (iii) The Trustee shall not be liable with respect to any action
     taken, suffered or omitted to be taken by it in good faith in accordance
     with the directions of the Guarantor or the Holders of Certificates
     evidencing Fractional Undivided Interests aggregating not less

                                      -92-

<PAGE>

     than 25% of the Trust Fund, if such action or non-action relates to the
     time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or other power conferred
     upon the Trustee under this Agreement;

          (iv) The Trustee shall not be required to take notice or be deemed to
     have notice or knowledge of any default or Event of Default unless a
     Responsible Officer of the Trustee's Corporate Trust Office shall have
     actual knowledge thereof. In the absence of such notice, the Trustee may
     conclusively assume there is no such default or Event of Default;

          (v) The Trustee shall not in any way be liable by reason of any
     insufficiency in any Account held by or in the name of Trustee unless it is
     determined by a court of competent jurisdiction that the Trustee's gross
     negligence or willful misconduct was the primary cause of such
     insufficiency (except to the extent that the Trustee is obligor and has
     defaulted thereon);

          (vi) Anything in this Agreement to the contrary notwithstanding, in no
     event shall the Trustee be liable for special, indirect or consequential
     loss or damage of any kind whatsoever (including but not limited to lost
     profits), even if the Trustee has been advised of the likelihood of such
     loss or damage and regardless of the form of action; and

          (vii) Neither EMC nor the Trustee shall be responsible for the acts or
     omissions of the other, it being understood that this Agreement shall not
     be construed to render them partners, joint venturers or agents of one
     another.

     The Trustee shall not be required 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 there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of the Master Servicer under this Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, the Master Servicer in accordance
with the terms of this Agreement.

     (e) All funds received by the Master Servicer and the Trustee and required
to be deposited in the Protected Accounts or Distribution Account pursuant to
this Agreement will be promptly so deposited by the Master Servicer and the
Trustee.

     (f) Except for those actions that the Trustee is required to take
hereunder, the Trustee shall not have any obligation or liability to take any
action or to refrain from taking any action hereunder in the absence of written
direction as provided hereunder.

     Section 9.02 CERTAIN MATTERS AFFECTING THE TRUSTEE. Except as otherwise
provided in Section 9.01:

          (i) The Trustee may rely and shall be protected in acting or
     refraining from acting in reliance on any resolution, certificate of a
     Seller, Master Servicer or Servicer, certificate of auditors or any other
     certificate, statement, instrument, opinion, report, notice, request,
     consent, order, appraisal, bond or other paper or document believed by it
     to be genuine and to have been signed or presented by the proper party or
     parties;

          (ii) The Trustee may consult with counsel and any advice of such
     counsel or any Opinion of Counsel shall be full and complete authorization
     and protection with respect to any action taken or suffered or omitted by
     it hereunder in good faith and in accordance with such advice or Opinion of
     Counsel:

          (iii) The Trustee shall not be under any obligation to exercise any of
     the trusts or powers vested in it by this Agreement, other than its
     obligation to give notices pursuant to this Agreement, or to institute,
     conduct or defend any litigation hereunder or in relation hereto at the
     request, order or direction of any of the Certificateholders pursuant to
     the provisions of this Agreement, unless such Certificateholders shall have
     offered to the Trustee reasonable security or indemnity against the costs,
     expenses and liabilities which may be incurred therein or thereby. Nothing
     contained herein shall, however, relieve the Trustee of the obligation,
     upon the occurrence of an Event of Default of which a Responsible Officer
     of the Trustee's Corporate Trust Office has actual knowledge (which has not
     been cured or waived), subject to Section 8.02(b), to exercise such of the
     rights and powers vested in it by this Agreement, and to use the same
     degree of care and skill in their exercise, as a prudent person would
     exercise under the circumstances in the conduct of his own affairs;

          (iv) Prior to the occurrence of an Event of Default hereunder and
     after the curing or waiver of all Events of Default which may have
     occurred, the Trustee shall not be liable in its individual capacity for
     any action taken, suffered or omitted by it in good faith and believed by
     it to be authorized or within the discretion or rights or powers conferred
     upon it by this Agreement;

          (v) The Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond or other paper or document, unless requested in writing to do so by
     Holders of Certificates evidencing Fractional Undivided Interests
     aggregating not less than 25% of the Trust Fund and provided that the
     payment within a reasonable time to the Trustee of the costs, expenses or
     liabilities likely to be incurred by it in the making of such investigation
     is, in the opinion of the Trustee, reasonably assured to the Trustee by the
     security afforded to it by the terms of this Agreement. The Trustee may
     require reasonable indemnity against such expense or liability as a
     condition to taking any such action. The reasonable expense of every such
     examination shall be paid by the Certificateholders requesting the
     investigation;

                                      -94-

<PAGE>

          (vi) The Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or through Affiliates, agents
     or attorneys; provided, however, that the Trustee may not appoint any agent
     to perform its custodial functions with respect to the Mortgage Files or
     paying agent functions under this Agreement without the express written
     consent of the Master Servicer, which consent will not be unreasonably
     withheld. The Trustee shall not be liable or responsible for the misconduct
     or negligence of any of the Trustee's agents or attorneys or a custodian or
     paying agent appointed hereunder by the Trustee with due care and, when
     required, with the consent of the Master Servicer;

          (vii) Should the Trustee deem the nature of any action required on its
     part, other than a payment or transfer under Subsection 4.01(b) or Section
     4.02, to be unclear, the Trustee may require prior to such action that it
     be provided by the Seller with reasonable further instructions;

          (viii) The right of the Trustee to perform any discretionary act
     enumerated in this Agreement shall not be construed as a duty, and the
     Trustee shall not be accountable for other than its negligence or willful
     misconduct in the performance of any such act;

          (ix) The Trustee shall not be required to give any bond or surety with
     respect to the execution of the trust created hereby or the powers granted
     hereunder, except as provided in Subsection 9.07; and

          (x) The Trustee shall not have any duty to conduct any affirmative
     investigation as to the occurrence of any condition requiring the
     repurchase of any Mortgage Loan by the Mortgage Loan Seller pursuant to
     this Agreement or the Mortgage Loan Purchase Agreement, as applicable, or
     the eligibility of any Mortgage Loan for purposes of this Agreement.

     Section 9.03 TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS. The
recitals contained herein and in the Certificates (other than the signature and
countersignature of the Trustee on the Certificates) shall be taken as the
statements of the Seller, and the Trustee shall not have any responsibility for
their correctness. The Trustee makes no representation as to the validity or
sufficiency of the Certificates (other than the signature and countersignature
of the Trustee on the Certificates) or of any Mortgage Loan except as expressly
provided in Sections 2.02 and 2.05 hereof; provided, however, that the foregoing
shall not relieve the Trustee of the obligation to review the Mortgage Files
pursuant to Sections 2.02 and 2.04. The Trustee's signature and countersignature
(or countersignature of its agent) on the Certificates shall be solely in its
capacity as Trustee and shall not constitute the Certificates an obligation of
the Trustee in any other capacity. The Trustee shall not be accountable for the
use or application by the Seller of any of the Certificates or of the proceeds
of such Certificates, or for the use or application of any funds paid to the
Seller with respect to the Mortgage Loans. Subject to the provisions of Section
2.05, the Trustee shall not be responsible for the legality or validity of this
Agreement or any document or instrument relating to this Agreement, the validity
of the execution of this Agreement or of any supplement hereto or instrument of
further assurance, or the validity, priority, perfection or sufficiency of the
security for the Certificates issued hereunder or intended to be issued
hereunder. The Trustee shall not at any time have any responsibility or
liability for or with respect to the legality, validity and enforceability

                                      -95-

<PAGE>

of any Mortgage or any Mortgage Loan, or the perfection and priority of any
Mortgage or the maintenance of any such perfection and priority, or for or with
respect to the sufficiency of the Trust Fund or its ability to generate the
payments to be distributed to Certificateholders, under this Agreement. The
Trustee shall not have any responsibility for filing any financing or
continuation statement in any public office at any time or to otherwise perfect
or maintain the perfection of any security interest or lien granted to it
hereunder or to record this Agreement.

     Section 9.04 TRUSTEE MAY OWN CERTIFICATES. The Trustee in its individual
capacity or in any capacity other than as Trustee hereunder may become the owner
or pledgee of any Certificates with the same rights it would have if it were not
Trustee, and may otherwise deal with the parties hereto.

     Section 9.05 TRUSTEE'S FEE AND COMPENSATION; EXPENSES. The Trustee will be
entitled to a Trustee Fee equal to the Trustee Fee Rate multiplied by the
aggregate stated principal balance of the mortgage loans as of the end of the
due period immediately preceding the Distribution Date. The Trustee Fee Rate is
0.01% per annum. The Trustee will also be entitled to any amounts earned on
funds in the Distribution Account.

     The Trustee will be entitled to recover from the Distribution Account
pursuant to Section 4.05(a) all reasonable out-of-pocket expenses, disbursements
and advances and the expenses of the Trustee, respectively, in connection with
any Event of Default, any breach of this Agreement or any claim or legal action
(including any pending or threatened claim or legal action) incurred or made by
the Trustee in the administration of the trusts hereunder (including the
reasonable compensation, expenses and disbursements of its counsel) except any
such expense, disbursement or advance as may arise from its negligence or
intentional misconduct or which is the responsibility of the Certificateholders
or the Trust Fund hereunder. If funds in the Distribution Account are
insufficient therefor, the Trustee shall recover such expenses from the Seller.
Such compensation and reimbursement obligation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust.

     Section 9.06 ELIGIBILITY REQUIREMENTS FOR TRUSTEE. The Trustee and any
successor Trustee shall during the entire duration of this Agreement be a state
bank or trust company or a national banking association organized and doing
business under the laws of such state or the United States of America,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus and undivided profits of at least $40,000,000 or, in the
case of a successor Trustee, $50,000,000, subject to supervision or examination
by federal or state authority and, in the case of the Trustee, rated "BBB" or
higher by Fitch with respect to their long-term rating and rated "BBB" or higher
by Standard & Poor's and "Baa2" or higher by Moody's with respect to any
outstanding long-term unsecured unsubordinated debt, and, in the case of a
successor Trustee, other than pursuant to Section 9.10, rated in one of the two
highest long-term debt categories of, or otherwise acceptable to, each of the
Rating Agencies. If the Trustee publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section 9.06 the combined
capital and surplus of such corporation shall be deemed to be its total equity
capital (combined capital and surplus) as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 9.06, the Trustee
shall resign immediately in the manner and with the effect specified in Section
9.08.

                                      -96-

<PAGE>

     Section 9.07 INSURANCE. The Trustee, at their own expense, shall at all
times maintain and keep in full force and effect: (i) fidelity insurance, (ii)
theft of documents insurance and (iii) forgery insurance (which may be
collectively satisfied by a "Financial Institution Bond" and/or a "Bankers'
Blanket Bond"). All such insurance shall be in amounts, with standard coverage
and subject to deductibles, as are customary for insurance typically maintained
by banks or their affiliates which act as custodians for investor-owned mortgage

with this Section 9.07 shall be furnished to any Certificateholder upon
reasonable written request.

any time resign and be discharged from the Trust hereby created by giving
written notice thereof to the Seller, the Guarantor and the Master Servicer,
with a copy to the Rating Agencies. Upon receiving such notice of resignation,
the Seller shall promptly appoint a successor Trustee acceptable to the
Guarantor, by written instrument, in triplicate, one copy of which instrument

     (b) If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.06 and shall fail to resign after written
request therefor by the Seller or the Guarantor or if at any time the Trustee
shall become incapable of acting, or shall be adjudged a bankrupt or insolvent,
or a receiver of the Trustee or of its property shall be appointed, or any
public officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Seller shall promptly remove the Trustee and appoint a successor Trustee
acceptable to the Guarantor, by written instrument, in triplicate, one copy of
which instrument shall be delivered to each of the Trustee removed and the
successor Trustee.

     (c) The Holders of Certificates evidencing Fractional Undivided Interests

quadruplicate, signed by such Holders or their attorneys-in-fact duly
authorized, one complete set of which instruments shall be delivered to the

     Section 9.09 SUCCESSOR TRUSTEE. (a) Any successor Trustee appointed as
provided in Section 9.08 shall execute, acknowledge and deliver to the Seller
and the Guarantor and to its predecessor Trustee an instrument accepting such
appointment hereunder. The resignation or removal of the predecessor Trustee
shall then become effective and such successor Trustee, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its predecessor hereunder, with like effect as if
originally named as Trustee herein. The predecessor Trustee shall after payment
of its outstanding fees and expenses promptly deliver to the successor Trustee
all assets and records of the Trust held by it hereunder, and the Seller and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in the successor Trustee all such rights, powers, duties and
obligations.

     (b) No successor Trustee shall accept appointment as provided in this
Section 9.09 unless at the time of such acceptance such successor Trustee shall
be eligible under the provisions of Section 9.06.

     (c) Upon acceptance of appointment by a successor Trustee as provided in
this Section 9.09, the successor Trustee shall mail notice of the succession of
such Trustee hereunder to all Certificateholders at their addresses as shown in
the Certificate Register and to the Rating Agencies. EMC shall pay the cost of
any mailing by the successor Trustee.

     Section 9.10 MERGER OR CONSOLIDATION OF TRUSTEE. Any state bank or trust
company or national banking association into which the Trustee may be merged or
converted or with which it may be consolidated or any state bank or trust
company or national banking association resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any state bank or trust
company or national banking association succeeding to all or substantially all
of the corporate trust business of the Trustee shall be the successor of the
Trustee hereunder, provided such state bank or trust company or national banking
association shall be eligible under the provisions of Section 9.06. Such
succession shall be valid without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding.

     Section 9.11 APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE. (a)
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust or property constituting the same may at the time be located, the Seller
and the Trustee acting jointly shall have the power and shall execute and
deliver all instruments to appoint one or more Persons approved by the Trustee
and the Seller to act as cotrustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust, and to
vest in such Person or Persons, in such capacity, such title to the Trust, or
any part thereof, and, subject to the other provisions of this Section 9.11,
such powers, duties, obligations, rights and trusts as the Seller and the
Trustee may consider necessary or desirable.

     (b) If the Seller shall not have joined in such appointment within 15 days
after the receipt by it of a written request so to do, the Trustee shall have
the power to make such appointment without the Seller.

                                      -98-

<PAGE>

     (c) No co-trustee or separate trustee hereunder shall be required to meet
the terms of eligibility as a successor Trustee under Section 9.06 hereunder and
no notice to Certificateholders of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 9.08 hereof.

     (d) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred on such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the 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 or any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

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

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

     (g) No trustee under this Agreement shall be personally liable by reason of
any act or omission of another trustee under this Agreement. The Seller and the
Trustee acting jointly may at any time accept the resignation of or remove any
separate trustee or co-trustee.

     Section 9.12 FEDERAL INFORMATION RETURNS AND REPORTS TO CERTIFICATEHOLDERS;
REMIC ADMINISTRATION. (a) For federal income tax purposes, the taxable year of
each REMIC shall be a calendar year shall maintain or cause the maintenance of
the books of each such REMIC on the accrual method of accounting.

     (b) The Trustee shall prepare and file or cause to be filed with the
Internal Revenue Service, and the Trustee shall sign, Federal tax information
returns or elections required to be made hereunder with respect to each REMIC I,
the Trust Fund, if applicable, and the Certificates containing such information
and at the times and in the manner as may be required by the Code or applicable
Treasury regulations, and shall furnish to each Holder of Certificates at any
time during

                                      -99-

<PAGE>

the calendar year for which such returns or reports are made such statements or
information at the times and in the manner as may be required thereby,
including, without limitation, reports relating to interest, original issue
discount and market discount or premium (using a constant prepayment assumption
of 25% CPR). The Trustee will apply for an Employee Identification Number from
the IRS under Form SS-4 or any other acceptable method for all tax entities. In
connection with the foregoing, the Trustee shall timely prepare and file, and
the Trustee shall sign, IRS Form 8811, which shall provide the name and address
of the person who can be contacted to obtain information required to be reported
to the holders of regular interests in each REMIC contained in the Trust Fund
(the "REMIC Reporting Agent"). The Trustee shall make elections to treat each
REMIC contained in the Trust Fund (which elections shall apply to the taxable
period ending December 31, 2002 and each calendar year thereafter) in such
manner as the Code or applicable Treasury regulations may prescribe. The Trustee
shall sign all tax information returns filed pursuant to this Section and any
other returns as may be required by the Code. The Holder of the Class R
Certificate is hereby designated as the "Tax Matters Person" (within the meaning
of Treas. Reg. ss.ss.1.860F-4(d)) for each REMIC contained in the Trust Fund.
The Trustee is hereby designated and appointed as the agent of each such Tax
Matters Person. Any Holder of a Residual Certificate will by acceptance thereof
appoint the Trustee as agent and attorney-in-fact for the purpose of acting as
Tax Matters Person for each REMIC contained in the Trust Fund during such time
as the Trustee does not own any such Residual Certificate. In the event that the
Code or applicable Treasury regulations prohibit the Trustee from signing tax or
information returns or other statements, or from acting as agent for the Tax
Matters Person, the Trustee shall take whatever action that in its sole good
faith judgment is necessary for the proper filing of such information returns or
for the provision of a tax matters person, including designation of the Holder
of a Residual Certificate to sign such returns or act as tax matters person.
Each Holder of a Residual Certificate shall be bound by this Section.

     (c) The Trustee shall provide upon request and receipt of reasonable
compensation, such information as required in Section 860D(a)(6)(B) of the Code
to the Internal Revenue Service, to any Person purporting to transfer a Residual
Certificate to a Person other than a transferee permitted by Section 5.05(b),
and to any regulated investment company, real estate investment trust, common
trust fund, partnership, trust, estate, organization described in Section 1381
of the Code, or nominee holding an interest in a pass-through entity described
in Section 860E(e)(6) of the Code, any record holder of which is not a
transferee permitted by Section 5.05(b) (or which is deemed by statute to be an
entity with a disqualified member).

     (d) The Trustee shall prepare and file or cause to be filed, and sign, any
state income tax returns required under Applicable State Law with respect to
each REMIC contained in the Trust Fund.

     (e) Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal withholding requirements respecting payments to
Certificateholders of interest or original issue discount on the Mortgage Loans,
that the Trustee reasonably believes are applicable under the Code. The consent
of Certificateholders shall not be required for such withholding. In the event
the Trustee withholds any amount from interest or original issue discount
payments or advances thereof to any Certificateholder pursuant to federal
withholding requirements, the Trustee shall, together with its monthly report to
such Certificateholders, indicate such amount withheld.

     (f) The Trustee agrees to indemnify the Trust Fund and the Seller for any
taxes and costs including, without limitation, any reasonable attorneys fees
imposed on or incurred by the Trust Fund, the Company or the Master Servicer, as
a result of a breach of the Trustee's covenants set forth in this Section 9.12;
provided, the Trustee shall not be liable or be obligated to indemnify the Trust
Fund for the failure by the other to perform any duty under this Agreement or
the breach by the other of any covenant in this Agreement.

                                   Termination

     Section 10.01 TERMINATION UPON REPURCHASE BY THE SELLER OR ITS DESIGNEE OR
LIQUIDATION OF THE MORTGAGE LOANS.

     (a) Subject to Section 10.02, the respective obligations and
responsibilities of the Seller, the Trustee, the Guarantor and the Master
Servicer created hereby, other than the obligation of the Trustee to make
payments to Certificateholders as hereinafter set forth shall terminate upon:

          (i) the repurchase by or at the direction of the Seller or its
     designee or the Guarantor of all Mortgage Loans and all related REO
     Property remaining in the Trust at a price equal to (a) 100% of the
     Outstanding Principal Balance of each Mortgage Loan (other than a Mortgage
     Loan related to REO Property) as of the date of repurchase, net of the
     principal portion of any unreimbursed Monthly Advances made by the
     purchaser, together with interest at the applicable Mortgage Interest Rate
     accrued but unpaid to, but not including, the first day of the month of
     repurchase, plus (b) the appraised value of any related REO Property, less
     the good faith estimate of the Seller of liquidation expenses to be
     incurred in connection with its disposal thereof (but not more than the
     Outstanding Principal Balance of the related Mortgage Loan, together with
     interest at the applicable Mortgage Interest Rate accrued on that balance
     but unpaid to, but not including, the first day of the month of
     repurchase), such appraisal to be calculated by an appraiser mutually
     agreed upon by the Seller, the Guarantor and the Trustee at the expense of
     the Seller, and (c) any unpaid Guarantor Reimbursement Amount and unpaid
     Guaranty Fee; or

          (ii) the later of the making of the final payment or other
     liquidation, or any advance with respect thereto, of the last Mortgage Loan
     remaining in the Trust Fund or the disposition of all property acquired
     with respect to any Mortgage Loan; provided, however, that in the event
     that an advance has been made, but not yet recovered, at the time of such
     termination, the Person having made such advance shall be entitled to
     receive, notwithstanding such termination, any payments received subsequent
     thereto with respect to which such advance was made; or

          (iii) the payment to Certificateholders of all amounts required to be
     paid to them pursuant to this Agreement.

     (b) In no event, however, shall the Trust created hereby continue beyond
the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James's, living on the date of this Agreement.

     (c) The right of the Seller or its designee to repurchase all the Mortgage
Loans pursuant to Subsection 10.01(a)(i) above shall be exercisable only if (i)
the aggregate Scheduled Principal Balance of the Mortgage Loans at the time of
any such repurchase is less than 10% of the Cut-off Date Balance or (ii) the
Seller, based upon an Opinion of Counsel, has determined that the REMIC status
of REMIC IA, in the case of Groups 1 and 2 or REMIC IB, in the case of Group 3,
has been

                                      -102-

<PAGE>

lost or that a substantial risk exists that such REMIC status will be lost for
the then-current taxable year. At any time thereafter, in the case of (i) or
(ii) above, the Seller may elect to terminate both REMIC IA and REMIC IB at any
time, and upon such election, the Seller or its designee, shall repurchase all
the Mortgage Loans in such REMICs.

     (d) If any of the Class I-A Certificates or Class II-A Certificates are
outstanding, the Guarantor shall have the right to purchase all of the Group 1
Mortgage Loans and Group 2 Mortgage Loans, as applicable, at the price set forth
in Subsection 10.01(a)(i) above. The right of the Guarantor to purchase all such
Mortgage Loans shall be exercisable only if the aggregate Scheduled Principal
Balance of the Mortgage Loans in the applicable Loan Group at the time of any
such repurchase is less than 5% of the related Cut-off Date Balance.

     (e) The Trustee shall give notice of any termination to the
Certificateholders, with a copy to the Master Servicer and the Rating Agencies,
upon which the Certificateholders shall surrender their Certificates to the
Trustee for payment of the final distribution and cancellation. Such notice
shall be given by letter, mailed not earlier than the l5th day and not later
than the 25th day of the month next preceding the month of such final
distribution, and shall specify (i) the Distribution Date upon which final
payment of the Certificates will be made upon presentation and surrender of the
Certificates at the office of the Trustee therein designated, (ii) the amount of
any such final payment and (iii) that the Record Date otherwise applicable to
such Distribution Date is not applicable, payments being made only upon
presentation and surrender of the Certificates at the office of the Trustee
therein specified.

     (f) If the option of the Seller to repurchase or cause the repurchase of
all the Mortgage Loans under Subsection 10.01 (a)(i) above is exercised, the
Seller and/or its designee shall deliver to the Trustee for deposit in the
Distribution Account, by the Business Day prior to the applicable Distribution
Date, an amount equal to the repurchase price for the Mortgage Loans being
purchased by it and all property acquired with respect to such Mortgage Loans
remaining in REMIC IA and REMIC IB. Upon presentation and surrender of the
Certificates by the Certificateholders, the Trustee shall distribute to the
Certificateholders an amount determined as follows: with respect to each
Certificate (other than the Class R Certificates), the outstanding Current
Principal Amount, plus with respect to each Certificate (other than the Class R
Certificates), one month's interest thereon at the applicable Pass-Through Rate;
and with respect to the Class R Certificates, the percentage interest evidenced
thereby multiplied by the difference, if any, between the above described
repurchase price and the aggregate amount to be distributed to the Holders of
the Certificates (other than the Class R Certificates). If the proceeds with
respect to the Group 1 Mortgage Loans are not sufficient to pay all of the Group
1 Certificates in full, any such deficiency will be allocated first, to the
Subordinate Certificates, in inverse order of their numerical designation, and
then to the Group 1 Senior Certificates on a pro rata basis. If the proceeds
with respect to the Group 2 Mortgage Loans are not sufficient to pay all of the
Group 2 Certificates in full, any such deficiency will be allocated first, to
the Subordinate Certificates, in inverse order of their numerical designation,
and then to the Group 2 Senior Certificates on a pro rata basis. If the proceeds
with respect to the Group 3 Mortgage Loans are not sufficient to pay all of the
Group 3 Certificates in full, any such deficiency will be allocated first, to
the Subordinate Certificates, in inverse order of their numerical designation,
and then to the Group 3 Senior Certificates on a pro rata basis. Upon deposit of
the required repurchase price and following such final Distribution Date, the
Trustee shall release promptly to the Seller and/or its

                                      -103-

<PAGE>

designee the Mortgage Files for the remaining applicable Mortgage Loans, and the
Accounts with respect thereto shall terminate, subject to the Trustee's
obligation to hold any amounts payable to Certificateholders in trust without
interest pending final distributions pursuant to Subsection 10.01(g). Any other
amounts remaining in the Accounts will belong to the Seller. Upon deposit of the
required repurchase price and following such final Distribution Date, the
Trustee shall release promptly to the Seller and/or its designee, as the case
may be, the Mortgage Files for the remaining Mortgage Loans, and the Accounts
with respect thereto shall terminate, subject to the Trustee's obligation to
hold any amounts payable to Certificateholders in trust without interest pending
final distributions pursuant to Subsection 10.01(g).

     (g) In the event that this Agreement is terminated by reason of the payment
or liquidation of all Mortgage Loans or the disposition of all property acquired
with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above, the
Master Servicer shall deliver to the Trustee for deposit in the Distribution
Account all distributable amounts remaining in the related Protected Account.
Upon the presentation and surrender of the Certificates, the Trustee shall
distribute to the remaining Certificateholders, in accordance with their
respective interests, all distributable amounts remaining in the Distribution
Account. Upon deposit by the Master Servicer of such distributable amounts, and
following such final Distribution Date, the Trustee shall release promptly to
the Seller or its designee the Mortgage Files for the remaining Mortgage Loans,
and the related Protected Account and the Distribution Account shall terminate,
subject to the Trustee's obligation to hold any amounts payable to the
Certificateholders in trust without interest pending final distributions
pursuant to this Subsection 10.01(g).

     (h) If not all of the Certificateholders shall surrender their Certificates
for cancellation within six months after the time specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Trustee may take appropriate steps, or appoint
any agent to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.

     Section 10.02 ADDITIONAL TERMINATION REQUIREMENTS. (a) If the option of the
Seller to repurchase all the Mortgage Loans under Subsection 10.01(a)(i) above
is exercised, or if the option of the Guarantor to repurchase the Group 1 and
Group 2 Mortgage Loans under Section 10.01 is exercised, the Trust Fund and each
REMIC shall be terminated in accordance with the following additional
requirements, unless the Trustee has been furnished with an Opinion of Counsel
to the effect that the failure of the Trust to comply with the requirements of
this Section 10.02 will not (i) result in the imposition of taxes on "prohibited
transactions" as defined in Section 860F of the Code on any or (ii) cause any
REMIC to fail to qualify as a REMIC at any time that any Regular Certificates
are outstanding:

          (i) within 90 days prior to the final Distribution Date, at the
     written direction of the Seller, the Trustee, as agent for the respective
     Tax Matters Persons, shall adopt a plan of complete liquidation of the
     related REMIC or REMICs in the case of a termination under Subsection
     10.01(a)(i), a plan of complete liquidation of REMIC IA and REMIC IB in the

                                      -104-

<PAGE>

     case of a termination under Subsection 10.01(c), or a plan of complete
     liquidation of REMIC IA in the case of a termination under Subsection
     10.01(d), provided to it by the Seller meeting the requirements of a
     "qualified liquidation" under Section 860F of the Code and any regulations
     thereunder.

          (ii) the Seller shall notify the Trustee at the commencement of such
     90-day liquidation period and, at or prior to the time of making of the
     final payment on the Certificates, the Trustee shall sell or otherwise
     dispose of all of the remaining assets of the Trust Fund in accordance with
     the terms hereof; and

          (iii) at or after the time of adoption of such a plan of complete
     liquidation of any REMIC and at or prior to the final Distribution Date,
     the Trustee shall sell for cash all of the assets of the Trust to or at the
     direction of the Seller or Guarantor, as applicable, and such REMIC, as
     applicable, shall terminate at such time.

     (b) By their acceptance of the Residual Certificates, the Holders thereof
hereby (i) agree to adopt such a plan of complete liquidation of the REMIC upon
the written request of the Seller or Guarantor, as applicable, and to take such
action in connection therewith as may be reasonably requested by the Seller or
Guarantor, as applicable, and (ii) appoint the Seller or Guarantor, as
applicable, as their attorney-in-fact, with full power of substitution, for
purposes of adopting such a plan of complete liquidation. The Trustee shall
adopt such plan of liquidation by filing the appropriate statement on the final
tax return of each REMIC. Upon complete liquidation or final distribution of all
of the assets of the Trust Fund, the Trust Fund and each REMIC shall terminate.

                            Miscellaneous Provisions

     Section 11.01 INTENT OF PARTIES. The parties intend that each of REMIC IA,
REMIC IB, REMIC II and REMIC III shall be treated as a REMIC for federal income
tax purposes and that the provisions of this Agreement should be construed in
furtherance of this intent.

     Section 11.02 AMENDMENT. (a) This Agreement may be amended from time to
time by the Seller, the Guarantor, the Master Servicer and the Trustee, without
notice to or the consent of any of the Certificateholders, to cure any
ambiguity, to correct or supplement any provisions herein or therein that may be
defective or inconsistent with any other provisions herein or therein, to comply
with any changes in the Code or to make any other provisions with respect to
matters or questions arising under this Agreement which shall not be
inconsistent with the provisions of this Agreement; provided, however, that such
action shall not, as evidenced by an Opinion of Independent Counsel, addressed
to the Trustee, adversely affect in any material respect the interests of any
Certificateholder.

     (b) This Agreement may also be amended from time to time by the Master
Servicer, the Guarantor, the Seller and the Trustee, with the consent of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than 51% of the Trust Fund or of the applicable Class or Classes, if
such amendment affects only such Class or Classes, for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the
Certificateholders; provided, however, that no such amendment shall (i) reduce
in any manner the amount of, or delay the timing of, payments received on
Mortgage Loans which are required to be distributed on any Certificate without
the consent of the Holder of such Certificate, (ii) reduce the aforesaid
percentage of Certificates the Holders of which are required to consent to any
such amendment, without the consent of the Holders of all Certificates then
outstanding, or (iii) cause any REMIC to fail to qualify as a REMIC for federal
income tax purposes, as evidenced by an Opinion of Independent Counsel which
shall be provided to the Trustee other than at the Trustee's expense.

giving or withholding of consents pursuant to Section 11.02(b), Certificates
registered in the name of or held for the benefit of the Seller, the Guarantor,
the Master Servicer, or the Trustee or any Affiliate thereof shall be entitled

such amendment to each Certificateholder, with a copy to the Rating Agencies.

     (d) In the case of an amendment under Subsection 11.02(b) above, it shall
not be necessary for the Certificateholders to approve the particular form of
such an amendment. Rather, it shall be sufficient if the Certificateholders
approve the substance of the amendment. The manner of obtaining such consents
and of evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable regulations as the
Trustee may prescribe.

applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all of the counties or other
comparable jurisdictions in which any or all of the Mortgaged Properties are
situated, and in any other appropriate public recording office or elsewhere. The
Seller shall effect such recordation, at the expense of the Trust upon the
request in writing of a Certificateholder, but only if such direction is
accompanied by an Opinion of Counsel (provided at the expense of the
Certificateholder requesting recordation) to the effect that such recordation
would materially and beneficially affect the interests of the Certificateholders
or is required by law.

     Section 11.04 LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS. (a) The death or
incapacity of any Certificateholder shall not terminate this Agreement or the
Trust, nor entitle such Certificateholder's legal representatives or heirs to
claim an accounting or to take any action or proceeding in any court for a
partition or winding up of the Trust, nor otherwise affect the rights,
obligations and liabilities of the parties hereto or any of them.

     (b) Except as expressly provided in this Agreement, no Certificateholders
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust, or the obligations of the parties hereto, nor shall
anything herein set forth, or contained in the terms of the Certificates, be
construed so as to establish the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholders be under
any liability to any third Person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

     (c) No Certificateholder shall have any right by virtue of any provision of
this Agreement to institute any suit, action or proceeding in equity or at law
upon, under or with respect to this Agreement against the Seller, the Master
Servicer or any successor to any such parties unless (i) such Certificateholder
previously shall have given to the Trustee a written notice of a continuing
default, as herein provided, (ii) the Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than 51% of the Trust Fund
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs and
expenses and liabilities to be incurred therein or thereby, and (iii) the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding.

     (d) No one or more Certificateholders shall have any right by virtue of any
provision of this Agreement to affect the rights of any other Certificateholders
or to obtain or seek to obtain priority or preference over any other such
Certificateholder, or to enforce any right under this Agreement, except in the
manner herein provided and for the equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
Section 11.04,

                                      -107-

<PAGE>

each and every Certificateholder and the Trustee shall be entitled to such
relief as can be given either at law or in equity.

     Section 11.05 ACTS OF CERTIFICATEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Agreement to be given or taken by Certificateholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Certificateholders in person or by an agent duly appointed in writing.
Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is expressly required, to the Seller. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Agreement and conclusive in favor of the Trustee and the Seller,
if made in the manner provided in this Section 11.05.

        (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such
execution is by a signer acting in a capacity other than his or her individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his or her authority. The fact and date of the execution of any such
instrument or writing, or the authority of the individual executing the same,
may also be proved in any other manner which the Trustee deems sufficient.

     (c) The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.02 made on a Certificate presented in accordance with
Section 5.04) shall be proved by the Certificate Register, and neither the
Trustee, the Seller, the Master Servicer nor any successor to any such parties
shall be affected by any notice to the contrary.

     (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action of the holder of any Certificate shall bind every future holder
of the same Certificate and the holder of every Certificate issued upon the
registration of transfer or exchange thereof, if applicable, or in lieu thereof
with respect to anything done, omitted or suffered to be done by the Trustee,
the Seller, the Master Servicer or any successor to any such party in reliance
thereon, whether or not notation of such action is made upon such Certificates.

     (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Certificates owned by the Trustee, the Guarantor, the Seller, the Master
Servicer or any Affiliate thereof shall be disregarded, except as otherwise
provided in Section 11.02(b) and except that, in determining whether the Trustee
shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent or waiver, only Certificates which the Trustee knows
to be so owned shall be so disregarded. Certificates which have been pledged in
good faith to the Trustee, the Seller, the Master Servicer or any Affiliate
thereof may be regarded as outstanding if the pledgor establishes to the
satisfaction of the Trustee the pledgor's right to act with respect to such
Certificates and that the pledgor is not an Affiliate of the Trustee, the
Guarantor, the Seller, or the Master Servicer, as the case may be.

     evidencing a fractional  undivided  interest in the distributions
     allocable to the Class [_-A] Certificates with respect to a Trust
     Fund consisting  primarily of a pool of adjustable  interest rate
     mortgage  loans  secured  by first  liens on  one-to-four  family
     residential   properties   sold  by  STRUCTURED   ASSET  MORTGAGE
     INVESTMENTS INC.

          This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Structured Asset Mortgage
Investments Inc., the Master Servicer or the Trustee referred to below or any of
their affiliates or any other person. Neither this Certificate nor the
underlying Mortgage Loans are guaranteed or insured by any governmental entity
or by Structured Asset Mortgage Investments Inc., the Master Servicer or the
Trustee or any of their affiliates or any other person, except as set forth in
the Agreement. None of Structured Asset Mortgage Investments Inc., the Master
Servicer or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

          This certifies that ________ is the registered owner of the Fractional
Undivided Interest evidenced hereby in the beneficial ownership interest of
Certificates of the same Class as this Certificate in a trust (the "Trust Fund")
generally consisting of adjustable rate mortgages loans secured by first lien on
one- to four-family residences, units in planned unit developments and
individual condominium units (collectively, the "Mortgage Loans") sold by
Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans were
sold by EMC Mortgage

                                       A-2

<PAGE>

Corporation (in such capacity, the "Mortgage Loan Seller") to SAMI. EMC Mortgage
Corporation will act as master servicer of the Mortgage Loans (in such capacity,
the "Master Servicer," which term includes any successors thereto under the
Agreement referred to below). The Trust Fund was created pursuant to the Pooling
and Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among SAMI, as seller (the "Seller"), Fannie Mae as guarantor (the
"Guarantor") with respect to the Class I-A and Class II-A Certificates, EMC
Mortgage Corporation as master servicer and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the Pass-Through
Rate set forth above and as further described in the Agreement. The Trustee will
distribute on the 25th day of each month, or, if such 25th day is not a Business
Day, the immediately following Business Day (each, a "Distribution Date"),
commencing on the First Distribution Date specified above, to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day (or if such last day is not a Business Day, the Business Day
immediately preceding such last day) of the calendar month preceding the month
of such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount (of interest and
principal, if any) required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month immediately following the month of the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the Current Principal Amount of this Class of Certificates will be reduced
to zero.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Person entitled thereto as such name and address
shall appear on the Certificate Register or, if such Person so requests by
notifying the Trustee in writing as specified in the Agreement. Notwithstanding
the above, the final distribution on this Certificate will be made after due
notice by the Trustee of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose and designated in such notice. The Initial
Current Principal Amount of this Certificate is set forth above. The Current
Principal Amount hereof will be reduced to the extent of distributions allocable
to principal hereon and any Realized Losses allocable hereto.

          This Certificate is one of a duly authorized issue of Certificates
designated as set forth on the face hereof (the "Certificates"), issued in ten
Classes. The Certificates, in the aggregate, evidence the entire beneficial
ownership interest in the Trust Fund formed pursuant to the Agreement.

          The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the Trust Fund for payment hereunder and that the
Trustee is not liable to the

                                       A-3

<PAGE>

Certificateholders for any amount payable under this Certificate or the
Agreement or, except as expressly provided in the Agreement, subject to any
liability under the Agreement.

          This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Seller, the Guarantor, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement from time to time by the Seller, the
Guarantor, the Master Servicer and the Trustee with the consent of the Holders
of Certificates evidencing Fractional Undivided Interests aggregating not less
than 51% (or in certain cases, Holders of Certificates of affected Classes
evidencing such percentage of the Fractional Undivided Interests thereof). Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable with the
Trustee upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Trustee for such purposes, duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Trustee duly executed by the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates in authorized
denominations representing a like aggregate Fractional Undivided Interest will
be issued to the designated transferee.

          The Certificates are issuable only as registered Certificates without
coupons in the Classes and denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, this
Certificate is exchangeable for one or more new Certificates evidencing the same
Class and in the same aggregate Fractional Undivided Interest, as requested by
the Holder surrendering the same.

          No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum

          The obligations created by the Agreement and the Trust Fund created
thereby (other than the obligations to make payments to Certificateholders with
respect to the termination of the Agreement) shall terminate upon the earlier of

repurchase by the party named in the Agreement of all the Mortgage Loans and
other assets of the Trust Fund in accordance with the terms of the Agreement.
Such optional repurchase may be made only on or after the Distribution Date on
which the aggregate unpaid principal balance of the Mortgage Loans specified in
the Agreement is less than the percentage of the aggregate Outstanding Principal
Balance of such Mortgage Loans at the Cut-off Date. The exercise of such right
will effect the early retirement of the Certificates. In no event, however, will
the Trust Fund created by the Agreement continue beyond the expiration of 21
years after the death of certain persons identified in the Agreement.

          Unless this Certificate has been countersigned by an authorized

                                  SERIES 2002-1

         evidencing a fractional undivided interest in the distributions
         allocable to the Class [B-_] Certificates with respect to a Trust Fund
         consisting primarily of a pool of adjustable interest rate mortgage
         loans secured by first liens on one-to-four family residential
         properties sold by STRUCTURED ASSET MORTGAGE INVESTMENTS INC.

          This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Structured Asset Mortgage
Investments Inc., the Master Servicer or the Trustee referred to below or any of
their affiliates or any other person. Neither this Certificate nor the
underlying Mortgage Loans are guaranteed or insured by any governmental entity
or by Structured Asset Mortgage Investments Inc., the Master Servicer or the
Trustee or any of their affiliates or any other person, except as set forth in
the Agreement. None of Structured Asset Mortgage Investments Inc., the Master
Servicer or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

          This certifies that _________ is the registered owner of the
Fractional Undivided Interest evidenced hereby in the beneficial ownership
interest of Certificates of the same Class as this Certificate in a trust (the
"Trust Fund") generally consisting of conventional adjustable rate mortgages
loans secured by first lien on one- to four- family residences, units in planned
unit developments and individual condominium (collectively, the "Mortgage
Loans") sold by Structured Asset Mortgage Investments Inc. ("SAMI"). The
Mortgage Loans were sold by EMC Mortgage Corporation (in such capacity, the
"Mortgage Loan Seller") to SAMI. EMC Mortgage Corporation

                                      A-2-2

<PAGE>

will act as master servicer of the Mortgage Loans (in such capacity, the "Master
Servicer," which term includes any successors thereto under the Agreement
referred to below). The Trust Fund was created pursuant to the Pooling and
Servicing Agreement dated as of the Cut-off Date specified above (the
"Agreement"), among SAMI, as seller (the "Seller"), Fannie Mae as guarantor (the
"Guarantor") with respect to the Class I-A and Class II-A Certificates, EMC
Mortgage Corporation as master servicer and Wells Fargo Bank Minnesota, National
Association, as trustee (the "Trustee"), a summary of certain of the pertinent
provisions of which is set forth hereafter. To the extent not defined herein,
capitalized terms used herein shall have the meaning ascribed to them in the
Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of its acceptance hereof assents and by which such
Holder is bound.

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the Pass-Through
Rate set forth above and as further described in the Agreement. The Trustee will
distribute on the 25th day of each month, or, if such 25th day is not a Business
Day, the immediately following Business Day (each, a "Distribution Date"),
commencing on the First Distribution Date specified above, to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day (or if such last day is not a Business Day, the Business Day
immediately preceding such last day) of the calendar month preceding the month
of such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount (of interest and
principal, if any) required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month immediately following the month of the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the Current Principal Amount of this Class of Certificates will be reduced
to zero.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Person entitled thereto as such name and address
shall appear on the Certificate Register or, if such Person so requests by
notifying the Trustee in writing as specified in the Agreement. Notwithstanding
the above, the final distribution on this Certificate will be made after due
notice by the Trustee of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose and designated in such notice. The Initial
Current Principal Amount of this Certificate is set forth above. The Current
Principal Amount hereof will be reduced to the extent of distributions allocable
to principal hereon and any Realized Losses allocable hereto.

          [This Certificate may not be acquired directly or indirectly by, or on
behalf of, an employee benefit plan or other retirement arrangement which is
subject to Title I of the Employee Retirement Income Security Act of 1974, as
amended, and/or Section 4975 of the Internal Revenue Code of 1986, as amended,
unless the proposed transfer and/or holding of a Certificate and the servicing,
management and/or operation of the trust and its assets: (i) will not result in
any prohibited transaction which is not covered under an individual or class
prohibited transaction exemption, including, but not limited to, Prohibited
Transaction Exemption ("PTE") 84-14, PTE 91-38, PTE 90-1, PTE 95-60 or PTE 96-23
and (ii) will not give rise to any additional fiduciary obligations on the part
of the Seller, the Master Servicer or the Trustee, which will be deemed
represented by an

                                      A-2-3

owner of a Book-Entry Certificate or a Global Certificate and will be evidenced
by a representation or an Opinion of Counsel to such effect by or on behalf of
an Institutional Accredited Investor.]

          This Certificate is one of a duly authorized issue of Certificates
designated as set forth on the face hereof (the "Certificates"), issued in ten
Classes. The Certificates, in the aggregate, evidence the entire beneficial
ownership interest in the Trust Fund formed pursuant to the Agreement.

          The Certificateholder, by its acceptance of this Certificate, agrees
that it will look solely to the Trust Fund for payment hereunder and that the
Trustee is not liable to the Certificateholders for any amount payable under
this Certificate or the Agreement or, except as expressly provided in the
Agreement, subject to any liability under the Agreement.

          This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Seller, the Guarantor, the Master Servicer, the Trustee and the rights of the
Certificateholders under the Agreement from time to time by the Seller, the
Guarantor, the Master Servicer and the Trustee with the consent of the Holders
of Certificates evidencing Fractional Undivided Interests aggregating not less
than 51% (or in certain cases, Holders of Certificates of affected Classes
evidencing such percentage of the Fractional Undivided Interests thereof). Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable with the
Trustee upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Trustee for such purposes, duly endorsed
by, or accompanied by a written instrument of transfer in form satisfactory to
the Trustee duly executed by the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates in authorized
denominations representing a like aggregate Fractional Undivided Interest will
be issued to the designated transferee.

          The Certificates are issuable only as registered Certificates without
coupons in the Classes and denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, this
Certificate is exchangeable for one or more new Certificates evidencing the same
Class and in the same aggregate Fractional Undivided Interest, as requested by
the Holder surrendering the same.

          No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Seller, the Master Servicer, the Trustee

                                      A-2-4

<PAGE>

and any agent of any of them may treat the Person in whose name this Certificate
is registered as the owner hereof for all purposes, and none of the Seller, the
Master Servicer, the Trustee or any such agent shall be affected by notice to
the contrary.

          The obligations created by the Agreement and the Trust Fund created
thereby (other than the obligations to make payments to Certificateholders with
respect to the termination of the Agreement) shall terminate upon the earlier of
(i) the later of the (A) final payment or other liquidation (or Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust Fund and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the Trust Fund in accordance with
the terms of the Agreement. Such optional repurchase may be made only on or
after the Distribution Date on which the aggregate unpaid principal balance of
the Mortgage Loans is less than the percentage of the aggregate Outstanding
Principal Balance of such Mortgage Loans at the Cut-off Date. The exercise of
such right will effect the early retirement of the Certificates. In no event,
however, will the Trust Fund created by the Agreement continue beyond the
expiration of 21 years after the death of certain persons identified in the
Agreement.

          Unless this Certificate has been countersigned by an authorized
signatory of the Trustee by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement, or be valid for any purpose.

                                  SERIES 2002-1

     evidencing  a  fractional  undivided  interest in the  distributions
     allocable to the Class R  Certificates  with respect to a Trust Fund
     consisting  primarily of a pool of adjustable interest rate mortgage
     loans  secured  by first  liens on  one-to-four  family  residential
     properties sold by STRUCTURED ASSET MORTGAGE INVESTMENTS INC.

          This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Structured Asset Mortgage
Investments Inc., the Master Servicer or the Trustee referred to below or any of
their affiliates or any other person. Neither this Certificate nor the
underlying Mortgage Loans are guaranteed or insured by any governmental entity
or by Structured Asset Mortgage Investments Inc., the Master Servicer or the
Trustee or any of their affiliates or any other person, except as set forth in
the Agreement. None of Structured Asset Mortgage Investments Inc., the Master
Servicer or any of their affiliates will have any obligation with respect to any
certificate or other obligation secured by or payable from payments on the
Certificates.

          This certifies that ______________________________ is the registered
owner of the Fractional Undivided Interest evidenced hereby in the beneficial
ownership interest of Certificates of the same Class as this Certificate in a
trust (the "Trust Fund") generally consisting of a pool of adjustable rate
mortgages loans secured by first liens on one- to four- family residential
properties, units in a planned development and individual condominium
(collectively, the "Mortgage Loans")

                                      A-3-3

<PAGE>

sold by Structured Asset Mortgage Investments Inc. ("SAMI"). The Mortgage Loans
were sold by EMC Mortgage Corporation (in such capacity, the"Mortgage Loan
Seller") to SAMI. EMC Mortgage Corporation will act as master servicer of the
Mortgage Loans (in such capacity, the "Master Servicer," which term includes any
successors thereto under the Agreement referred to below). The Trust Fund was
created pursuant to the Pooling and Servicing Agreement dated as of the Cut-off
Date specified above (the "Agreement"), among SAMI, as seller (the "Seller"),
Fannie Mae as guarantor (the "Guarantor") with respect to the Class I-A and
Class II-A Certificates, EMC Mortgage Corporation as master servicer and Wells
Fargo Bank Minnesota, National Association, as trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth hereafter.
To the extent not defined herein, capitalized terms used herein shall have the
meaning ascribed to them in the Agreement. This Certificate is issued under and
is subject to the terms, provisions and conditions of the Agreement, to which
Agreement the Holder of this Certificate by virtue of its acceptance hereof
assents and by which such Holder is bound.

          Interest on this Certificate will accrue during the month prior to the
month in which a Distribution Date (as hereinafter defined) occurs on the
Current Principal Amount hereof at a per annum rate equal to the Pass-Through
Rate set forth above and as further described in the Agreement. The Trustee will
distribute on the 25th day of each month, or, if such 25th day is not a Business
Day, the immediately following Business Day (each, a "Distribution Date"),
commencing on the First Distribution Date specified above, to the Person in
whose name this Certificate is registered at the close of business on the last
Business Day (or if such last day is not a Business Day, the Business Day
immediately preceding such last day) of the calendar month preceding the month
of such Distribution Date, an amount equal to the product of the Fractional
Undivided Interest evidenced by this Certificate and the amount (of interest and
principal, if any) required to be distributed to the Holders of Certificates of
the same Class as this Certificate. The Assumed Final Distribution Date is the
Distribution Date in the month immediately following the month of the latest
scheduled maturity date of any Mortgage Loan and is not likely to be the date on
which the Current Principal Amount of this Class of Certificates will be reduced
to zero.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the address of the Person entitled thereto as such name and address
shall appear on the Certificate Register. Notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency appointed by the Trustee for that
purpose and designated in such notice. The Initial Current Principal Amount of
this Certificate is set forth above. The Current Principal Amount hereof will be
reduced to the extent of distributions allocable to principal hereon and any
Realized Losses allocable hereto.

          Each Holder of this Certificate will be deemed to have agreed to be
bound by the restrictions set forth in the Agreement to the effect that (i) each
person holding or acquiring any Ownership Interest in this Certificate must be a
United States Person and a Permitted Transferee, (ii) the transfer of any
Ownership Interest in this Certificate will be conditioned upon the delivery to
the Trustee of, among other things, an affidavit to the effect that it is a
United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted

                                      A-3-4

<PAGE>

Transferee acquires any Ownership Interest in this Certificate in violation of
such restrictions, then the Seller will have the right, in its sole discretion
and without notice to the Holder of this Certificate, to sell this Certificate
to a purchaser selected by the Seller, which purchaser may be the Seller, or any
affiliate of the Seller, on such terms and conditions as the Seller may choose.

          In connection with any transfer of this Certificate, the Trustee will
also require either (i) an opinion of counsel acceptable to and in form and
substance satisfactory to the Trustee with respect to the permissibility of such
transfer under the Employee Retirement Income Security Act of 1974, as amended
("ERISA") and Section 4975 of the Internal Revenue Code (the "Code") and
stating, among other things, that the transferee's acquisition of a Class R
Certificate will not constitute or result in a non-exempt prohibited transaction
under Section 406 of ERISA or Section 4975 of the Code or (ii) a representation
letter, in the form as described by the Agreement, stating that the transferee
is not an employee benefit or other plan subject to the prohibited transaction
provisions of ERISA or Section 4975 of the Code (a "Plan"), or any other person
(including an investment manager, a named fiduciary or a trustee of any Plan)
acting, directly or indirectly, on behalf of or purchasing any Certificate with
"plan assets" of any Plan.

          This Certificate is one of a duly authorized issue of Certificates
designated as set forth on the face hereof (the "Certificates"), issued in ten
Classes. The Certificates, in the aggregate, evidence the entire beneficial
ownership interest in the Trust Fund formed pursuant to the Agreement.

          The Certificateholder, by acceptance of this Certificate, agrees that
it will look solely to the Trust Fund for payment hereunder and that the Trustee
is not liable to the Certificateholders for any amount payable under this
Certificate or the Agreement or, except as expressly provided in the Agreement,
subject to any liability under the Agreement.

          This Certificate does not purport to summarize the Agreement and
reference is made to the Agreement for the interests, rights and limitations of
rights, benefits, obligations and duties evidenced hereby, and the rights,
duties and immunities of the Trustee.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Seller, the Guarantor, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement from time to time by the Seller, the
Guarantor, the Master Servicer and the Trustee, with the consent of the Holders
of Certificates evidencing Fractional Undivided Interests aggregating not less
than 51% (or in certain cases, Holders of Certificates of affected Classes
evidencing such percentage of the Fractional Undivided Interests thereof). Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without the
consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable with the
Trustee upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Trustee for such purposes, duly

                                      A-3-5

<PAGE>

endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee or transferees.

          The Certificates are issuable only as registered Certificates without
coupons in the Classes and denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, this
Certificate is exchangeable for one or more new Certificates evidencing the same
Class and in the same aggregate Fractional Undivided Interest, as requested by
the Holder surrendering the same.

          No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith.

          The Company, the Seller, the Master Servicer, the Trustee and any
agent of any of them may treat the Person in whose name this Certificate is
registered as the Owner hereof for all purposes, and none of the Seller, the
Master Servicer, the Trustee or any such agent shall be affected by notice to
the contrary.

          The obligations created by the Agreement and the Trust Fund created
thereby (other than the obligations to make payments to Certificateholders with
respect to the termination of the Agreement) shall terminate upon the earlier of
(i) the later of the (A) final payment or other liquidation (or Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust Fund and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the Trust Fund in accordance with
the terms of the Agreement. Such optional repurchase may be made only on or
after the Distribution Date on which the aggregate unpaid principal balance of
the Mortgage Loans is less than the percentage of the aggregate Outstanding
Principal Balance specified in the Agreement of such Mortgage Loans at the
Cut-off Date. The exercise of such right will effect the early retirement of the
Certificates. In no event, however, will the Trust Fund created by the Agreement
continue beyond the expiration of 21 years after the death of certain persons
identified in the Agreement.

          Unless this Certificate has been countersigned by an authorized
signatory of the Trustee by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement, or be valid for any purpose.

          (the "Privately Offered Certificates")
          ----------------------------------------------------------------------

Dear Ladies and Gentlemen:

     In connection with our purchase of Privately Offered Certificates, we
confirm that:

          (i)  we understand that the Privately Offered Certificates are not
               being registered under the Securities Act of 1933, as amended
               (the "Act") or any applicable state securities or "Blue Sky"
               laws, and are being sold to us in a transaction that is exempt
               from the registration requirements of such laws;

          (ii) any information we desired concerning the Certificates, including
               the Privately Offered Certificates, the trust in which the
               Certificates represent the entire beneficial ownership interest
               (the "Trust") or any other matter we deemed relevant to our
               decision to purchase Privately Offered Certificates has been made
               available to us;

          (iii) we are able to bear the economic risk of investment in Privately
               Offered Certificates; we are an institutional "accredited
               investor" as defined in Section 501(a) of Regulation D
               promulgated under the Act and a sophisticated institutional
               investor;

          (iv) we are acquiring Privately Offered Certificates for our own
               account, not as nominee for any other person, and not with a
               present view to any distribution or other disposition of the
               Privately Offered Certificates;

          (v)  we agree the Privately Offered Certificates must be held
               indefinitely by us (and may not be sold, pledged, hypothecated or
               in any way disposed of)

                                      F-1-1

               unless subsequently registered under the Act and any applicable
               state securities or "Blue Sky" laws or an exemption from the
               registration requirements of the Act and any applicable state
               securities or "Blue Sky" laws is available;

          (vi) we agree that in the event that at some future time we wish to
               dispose of or exchange any of the Privately Offered Certificates
               (such disposition or exchange not being currently foreseen or
               contemplated), we will not transfer or exchange any of the
               Privately Offered Certificates unless:

               below), (2) if required by the Pooling and Servicing Agreement

               the Pooling and Servicing Agreement (as defined below) (or such
               other documentation as may be acceptable to the Trustee) is
               executed promptly by the purchaser and delivered to the
               addressees hereof and (3) all offers or solicitations in
               connection with the sale, whether directly or through any agent
               acting on our behalf, are limited only to Eligible Purchasers and
               are not made by means of any form of general solicitation or
               general advertising whatsoever; and

                    (B) if the Privately Offered Certificate is not registered
               under the Act (as to which we acknowledge you have no
               obligation), the Privately Offered Certificate is sold in a
               transaction that does not require registration under the Act and
               any applicable state securities or "blue sky" laws and, if Bank
               One, National Association (the "Trustee") so requests, a
               satisfactory Opinion of Counsel is furnished to such effect,
               which Opinion of Counsel shall be an expense of the transferor or
               the transferee;

         (vii) we agree to be bound by all of the terms (including those
               relating to restrictions on transfer) of the Pooling and
               Servicing, pursuant to which the Trust was formed; we have
               reviewed carefully and understand the terms of the Pooling and
               Servicing Agreement;

        (viii) we either: (i) are not acquiring the Privately Offered
               Certificate directly or indirectly by, or on behalf of, an
               employee benefit plan or other retirement arrangement which is

resale, pledge or transfer is being made in reliance in Rule 144A, or (ii) an
institutional "accredited investor," as such term is defined under Rule 501 of
the Act in a transaction that otherwise does not constitute a public offering.

     The undersigned agrees that if at some future time it wishes to dispose of

Certificates, if the proposed Transferee is an institutional "accredited
investor," the transferor shall obtain from the transferee and deliver to the
addressees hereof an Investment Letter in the form attached to the Pooling and
Servicing Agreement, dated as of January 1, 2002, among Structured Asset
Mortgage Investments Inc., Fannie Mae, as guarantor with respect to the Class
I-A Certificates and the Class II-A Certificates, EMC Mortgage Corporation, as

trustee, pursuant to Certificates were issued.

     The undersigned certifies that it either: (i) is not acquiring the
Privately Offered Certificate directly or indirectly by, or on behalf of, an
employee benefit plan or other retirement arrangement which is subject to Title
I of the Employee Retirement Income Security Act of 1974, as amended, and/or
section 4975 of the Internal Revenue Code of 1986, as amended, or (ii) is
providing a representation or an opinion of counsel to the effect that the
proposed transfer and/or holding of a Privately Offered Certificate and the
servicing, management and/or operation of the Trust and its assets: (I) will not
result in any prohibited transaction which is not covered under a prohibited
transaction exemption, including, but not limited to, Prohibited Transaction
Exemption ("PTE") 84- 14, PTE 91-38, PTE 90-1, PTE 95-60, PTE 96-23 or Section
401(c) of ERISA and the regulations to be promulgated thereunder and (II) will
not give rise to any additional fiduciary duties on the part of the Seller, the
Master Servicer or the Trustee.

     If the Purchaser proposes that its Certificates be registered in the name
of a nominee on its behalf, the Purchaser has identified such nominee below, and

         This Pooling and Servicing Agreement, dated and effective as of January
1, 2002, is entered into among Impac Secured Assets Corp., as company (the
"Company"), Impac Funding Corporation, as master servicer (the "Master
Servicer"), and Bankers Trust Company of California, N.A., as trustee (the
"Trustee").

                             PRELIMINARY STATEMENT:

         The Company 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 fourteen classes of
certificates, designated as (i) the Class A-I-1, (ii) Class A-I-2, (iii) Class
A-I-3, (iv) Class A-I-4, (v) Class A-I-5, (vi) Class A-I-6, (vii) Class A-II,
(viii) Class A-IO Certificates, (ix) the Class M-1 Certificates, (x) the Class
M-2 Certificates, (xi) the Class B Certificates, (xii) the Class P Certificates,
(xiii) the Class C Certificates and (xiv) the Class R Certificates.

                                     REMIC 1
                                     -------

         As provided herein, 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 (exclusive of the Pre-Funding Account,
the Interest Coverage Account and the Net WAC Shortfall Reserve Fund) 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 herein) 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.

-------------------
(1)      Solely for purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
         regulations, the Distribution Date in the month following the maturity
         date for the Mortgage Loan with the latest possible maturity date has
         been designated as the "latest possible maturity date" for each Class
         of Certificates that represents one or more of the "regular interests"
         in REMIC 3.
(2)      Calculated in accordance with the definition of "Pass-Through Rate"
         herein.
(3)      The Class C Certificates will accrue interest at their variable
         Pass-Through Rate on the Notional Amount of the Class C Certificates
         outstanding from time to time which shall equal the aggregate of the
         Uncertificated Principal Balances of the REMIC 2 Regular Interests. The
         Class C Certificates will not accrue interest on their Certificate
         Principal Balance.
(4)      The Class A-IO Certificates do not have a Certificate Principal Balance
         and are not entitled to distributions of principal. The Class A-IO
         Certificates accrue interest on a Notional Amount calculated in
         accordance with the definition of "Notional Amount" herein.
(5)      The Class P Certificates do not accrue interest.

         Using the Structuring Assumptions (as defined in the Prospectus
Supplement) and assuming a 0.00% Prepayment Assumption, no losses or
delinquencies on the Mortgage Loans, and an Overcollateralization Target Amount
of $0, the final scheduled Distribution Date on each Class of Certificates would
be as follows: (i) for the Class A-I-1 Certificates, the Distribution Date in
June 2016; (ii) for the Class A-I-2 Certificates, the Distribution Date in
August 2019; (iii) for the Class A-I-3 Certificates, the Distribution Date in
March 2023; (iv) for the Class A-I-4 Certificates, the Distribution Date in
November 2027; (v) for the Class A-IO Certificates, the Distribution Date in
July 2004; and (v) for the Class A-I-5, Class A-I-6, Class A-II, Class M, Class
B and Class C Certificates, the Distribution Date in April 2032.

         Due to Realized Losses, principal prepayments (including Principal
Prepayments, liquidations of defaulted Mortgage Loans, repurchases of Mortgage
Loans) and other differences between the Structuring Assumptions and the actual
behavior that the Mortgage Loans will exhibit during the period that they are
held in the Trust Fund, the final scheduled Distribution Date on each Class of
Certificates may be substantially earlier or later than the dates indicated in
the preceding paragraph. The failure of any Class of Certificates to be retired
on or before the applicable date indicated in the preceding paragraph shall not
constitute an Event of Default or a breach by any party hereto, nor shall any
Certificateholder (or the Trustee on behalf of any Certificateholder) be
entitled to any remedy for such failure. The termination of the Trust Fund and
the final distribution on any Class of the Certificates shall only occur in
accordance with the provisions of Article IX of this Agreement.

Class A-I-1

                                       50
<PAGE>

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 Class A-I-1 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 Class A-I-1 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 (over which the Trustee has no control), used for determining
one-month Eurodollar lending rates that is calculated and published (or
otherwise made available) by an independent party.

         The establishment of LIBOR by the Trustee on any LIBOR Rate Adjustment
Date and the Trustee's subsequent calculation of the Pass-Through Rate
applicable to the Class A-I-1 Certificates for the relevant Accrual Period, in
the absence of manifest error, will be final and binding.

         Promptly following each LIBOR Rate Adjustment Date the Trustee shall
supply the Master Servicer with the results of its determination of LIBOR on
such date. Furthermore, the Trustee will supply to any Certificateholder so
requesting by telephone the Pass-Through Rate on the Class A-I-1 Certificates
for the current and the immediately preceding Accrual Period.

Servicer on or with respect to the Mortgage Loans (other than payment of
principal and interest due on or before the Cut-off Date or Subsequent Cut-off
Date, as applicable).

         The Master Servicer hereby acknowledges the receipt by it of cash in an
amount equal to $265,625.70 (the "Special Deposit"), representing interest at
the Mortgage Rate, for the calendar month of January 2002, for those Mortgage
Loans which do not have Monthly Payments due on February 1, 2002. The Master
Servicer shall hold such amount in the Custodial Account and shall include such
amount in the Available Distribution Amount for the Distribution Date in
February 2002.

         The Trustee hereby acknowledges the receipt by it of the Pre-Funded
Amount and the Interest Coverage Amount.

         In connection with such transfer and assignment, the Company has caused
the Seller to deliver to, and deposit with the Trustee, as described in the
Mortgage Loan Purchase Agreement, with respect to each Initial Mortgage Loan,
and as described in the Subsequent Mortgage Loan Purchase Agreement, with
respect to each Subsequent Mortgage Loan, the following documents or
instruments:

         (i) the original Mortgage Note endorsed without recourse, "Bankers
Trust Company of California, N.A., as trustee under the Pooling and Servicing
Agreement relating to Impac Secured Assets Corp., Mortgage Pass-Through
Certificates, Series 2002-1" 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

                                       54
<PAGE>

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 Seller 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
recordable form to "Bankers Trust Company of California, N.A., as trustee," or
to "Bankers Trust Company of California, N.A., as trustee for holders of Impac
Secured Assets Corp., Mortgage Pass-Through Certificates, Series 2002-1";

         (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 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 Seller 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 Seller is obligated as described in the Mortgage Loan Purchase
Agreement, with respect to the Initial Mortgage Loans, and will be obligated as
described in the Subsequent Mortgage Loan Purchase Agreement, with respect to
the Subsequent Mortgage Loans, to deliver to the Trustee: (a) either the
original recorded Mortgage, or in the event such original cannot be delivered by
the Seller, 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 Seller was delivered to the Trustee 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 Seller, or in the event such original cannot be delivered by
the Seller, 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 Seller were delivered to the Trustee pursuant to clause
(iv) above. However, pursuant to the Mortgage Loan Purchase Agreement (or the
Subsequent Mortgage Loan Purchase Agreement, with respect to the Subsequent
Mortgage Loans), the Seller 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

                                       55
<PAGE>

Seller 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 Seller 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
Seller, (iv) the occurrence of a servicing transfer as described in Section 7.02
hereof and (v) if the Seller 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 Seller shall be deemed to have
satisfied its obligations hereunder upon delivery to the Trustee 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 Trustee because
of any defect therein, the Seller is required, as described in the Mortgage Loan
Purchase Agreement (or the Subsequent Mortgage Loan Purchase Agreement, as
applicable), to prepare a substitute Assignment or cure such defect, as the case
may be, and the Seller shall cause such Assignment to be recorded in accordance
with this section.

         The Seller is required as described in the Mortgage Loan Purchase
Agreement, with respect to the Initial Mortgage Loans, and will be required as
described in the Subsequent Mortgage Loan Purchase Agreement, with respect to
the Subsequent Mortgage Loans, to exercise its best reasonable efforts to
deliver or cause to be delivered to the Trustee within 120 days of the Closing
Date, with respect to the Initial Mortgage Loans, or the Subsequent Transfer
Date, with respect to the Subsequent 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 Seller further agrees that it will cause, at the
Seller's own expense, as of the Closing Date, the MERS(R) System to indicate
that such Mortgage Loans have been assigned by the Seller to the Trustee in
accordance with this Agreement for the benefit of the Certificateholders 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 Company 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.

                                       56
<PAGE>

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

         Except as may otherwise expressly be provided herein, none of the
Company, 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 Company
to the Trustee as provided in this Section be, and be construed as, a sale of
the Mortgage Loans and the REMIC 1 Regular Interests as provided for in this
Section 2.01 by the Company to the Trustee for the benefit of the
Certificateholders. It is, further, not intended that such conveyance be deemed
a pledge of the Mortgage Loans and the REMIC 1 Regular Interests by the Company
to the Trustee to secure a debt or other obligation of the Company. However, in
the event that the Mortgage Loans and the REMIC 1 Regular Interests are held to
be property of the Company, or if for any reason this Agreement is held or
deemed to create a security interest in the Mortgage Loans and the REMIC 1
Regular Interests, 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 Company to the Trustee of a security interest
in all of the Company'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, (C) the REMIC 1 Regular Interests and (D) 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 Company to the Trustee of any security interest in any and
all of the Seller'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 (D); (c) the possession by the
Trustee or any other 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
Company and the

                                       57
<PAGE>

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.

         Section 2.02.     Acceptance of the Trust Fund by the Trustee.

         The Trustee acknowledges receipt (subject to any exceptions noted in
the Initial Certification described below), 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 Trustee agrees, for the benefit of the Certificateholders, 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 Trustee agrees to execute and deliver, or cause
to be executed and delivered, to the Company and the Master Servicer on the
Closing Date, with respect to each Initial Mortgage Loan, or the Subsequent
Transfer Date, with respect to each Subsequent 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) and (iv) of the definition of the "Mortgage
Loan Schedule" accurately reflects information set forth in the Mortgage File.
Neither the Trustee nor 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. Neither the Trustee nor 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 Initial
Mortgage Loans, (or Subsequent Transfer Date, with respect to the Subsequent
Mortgage Loans) the Trustee shall deliver to the Company 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.

                                       58
<PAGE>

         If in the process of reviewing the Mortgage Files and preparing the
certifications referred to above the Trustee finds any document or documents
constituting a part of a Mortgage File to be missing or defective in any
material respect, the Trustee shall promptly notify the Seller, the Master
Servicer and the Company. The Trustee shall promptly notify the Seller of such
defect and request that the Seller cure any such defect within 60 days from the
date on which the Seller was notified of such defect, and if the Seller does not
cure such defect in all material respects during such period, request on behalf
of the Certificateholders that the Seller purchase such Mortgage Loan from the
Trust Fund at the Purchase Price within 90 days after the date on which the
Seller 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 Seller 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
Certificateholders 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 Trustee shall release or cause to be released to the
Seller the related Mortgage File and shall execute and deliver such instruments
of transfer or assignment, in each case without recourse, as the Seller shall
require as necessary to vest in the Seller ownership of any Mortgage Loan
released pursuant hereto and at such time the Trustee shall have no further
responsibility with respect to the related Mortgage File. In furtherance of the
foregoing, if the Seller 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 Seller
and shall cause such Mortgage to be removed from registration on the MERS(R)
System in accordance with MERS' rules and regulations.

         Section 2.03.     Representations, Warranties and Covenants of the
                           Master Servicer and the Company.

         (a) The Master Servicer hereby represents and warrants to and covenants
with the Company and the Trustee for the benefit of Certificateholders that:

                  (i) The Master Servicer is, and throughout the term hereof

<PAGE>

not violate the Master Servicer's articles of incorporation or bylaws or
constitute a default (or an event which, with notice or lapse of time, or both,
would constitute a default) under, or result in the breach of, any material
agreement or other instrument to which it is a party or which is applicable to
it or any of its assets;

                  (iii) The Master Servicer has the full power and authority to
enter into and consummate all transactions contemplated by this Agreement, has
duly authorized the execution, delivery and performance of this Agreement, and
has duly executed and delivered this Agreement;

                  (iv) This Agreement, assuming due authorization, execution and
delivery by the Company and the Trustee, constitutes a valid, legal and binding
obligation of the Master Servicer, enforceable against the Master Servicer in
accordance with the terms hereof, subject to (A) applicable bankruptcy,
insolvency, reorganization, moratorium and other laws affecting the enforcement
of creditors' rights generally, and (B) general principles of equity, regardless
of whether such enforcement is considered in a proceeding in equity or at law;

                  (v) The Master Servicer is not in violation of, and its
execution and delivery of this Agreement and its performance and compliance with
the terms of this Agreement will not constitute a violation of, any law, any
order or decree of any court or arbiter, or any order, regulation or demand of
any federal, state or local governmental or regulatory authority, which
violation is likely to affect materially and adversely either the ability of the
Master Servicer to perform its obligations under this Agreement or the financial
condition of the Master Servicer;

                  (vi) No litigation is pending (other than litigation with
respect to which pleadings or documents have been filed with a court, but not
served on the Master Servicer) or, to the best of the Master Servicer's
knowledge, threatened against the Master Servicer which would prohibit its
entering into this Agreement or performing its obligations under this Agreement
or is likely to affect materially and adversely either the ability of the Master
Servicer to perform its obligations under this Agreement or the financial
condition of the Master Servicer;

                  (vii) The Master Servicer will comply in all material respects
in the performance of this Agreement with all reasonable rules and requirements
of each insurer under each Insurance Policy;

                  (viii) The execution of this Agreement and the performance of

                  (ix) No information, certificate of an officer, statement

of the Master Servicer, contain any untrue statement of a material fact;

                                       60
<PAGE>

                  (x) The Master Servicer will not waive any Prepayment Charge
unless it is waived in accordance with the standard set forth in Section 3.01;
and

                  (xi) The Master Servicer is a member of MERS in good standing,
and will comply in all material respects with the rules and procedures of MERS
in connection with the servicing of the Mortgage Loans that are registered with
MERS.

         It is understood and agreed that the representations, warranties and
covenants set forth in this Section 2.03(a) shall survive the execution and
delivery of this Agreement, and shall inure to the benefit of the Company, the
Trustee and the Certificateholders. Upon discovery by the Company, the Trustee
or the Master Servicer of a breach of any of the foregoing representations,
warranties and covenants that materially and adversely affects the interests of
the Company or the Trustee, the party discovering such breach shall give prompt
written notice to the other parties. Notwithstanding the foregoing, within 90
days of the earlier of discovery by the Master Servicer or receipt of notice by
the Master Servicer of the breach of the covenant of the Master Servicer set
forth in Section 2.03(x) above which materially and adversely affects the
interests of the Holders of the Class P Certificates in any Prepayment Charge,
the Master Servicer shall remedy such breach as follows: the Master Servicer
shall pay the amount of such waived Prepayment Charge, for the benefit of the
holders of the Class P Certificates, by depositing such amount into the
Custodial Account (net of any amount actually collected by the Master Servicer
in respect of such Prepayment Charge and remitted by the Master Servicer, for
the benefit of the Holders of the Class P Certificates, in respect of such
Prepayment Charge, into the Custodial Account). The foregoing shall not,
however, limit any remedies available to the Certificateholders, the Company or
the Trustee on behalf of the Certificateholders, pursuant to the Mortgage Loan
Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement respecting
a breach of any of the representations, warranties and covenants contained in
the Mortgage Loan Purchase Agreement or the Subsequent Mortgage Loan Purchase
Agreement.

         (b) The Company hereby represents and warrants to the Master Servicer
and the Trustee for the benefit of Certificateholders that as of the Closing
Date, the representations and warranties of the Seller with respect to the
Mortgage Loans and the remedies therefor that are contained in the Mortgage Loan
Purchase Agreement or the Subsequent Mortgage Loan Purchase Agreement are as set
forth in Exhibit I 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 Trustee.

         Upon discovery by either the Company, the Master Servicer or the
Trustee of a breach of any representation or warranty set forth in this Section
2.03 which materially and adversely affects the interests of the
Certificateholders in any Mortgage Loan, the party discovering such breach shall
give prompt written notice to the other parties.

         Section 2.04.     Representations and Warranties of the Seller.

                                       61
<PAGE>

         The Company hereby assigns to the Trustee for the benefit of
Certificateholders all of its rights (but none of its obligations) in, to and
under the Mortgage Loan Purchase Agreement and the Subsequent Mortgage Loan
Purchase Agreement. Insofar as the Mortgage Loan Purchase Agreement (and the
Subsequent Mortgage Loan Purchase Agreement, with respect to the Subsequent
Mortgage Loans) relates to such representations and warranties and any remedies
provided thereunder for any breach of such representations and warranties, such
right, title and interest may be enforced by the Trustee on behalf of the
Certificateholders. Upon the discovery by the Company, the Master Servicer or
the Trustee of a breach of any of the representations and warranties made in the
Mortgage Loan Purchase Agreement in respect of any Mortgage Loan (and the
Subsequent Mortgage Loan Purchase Agreement, with respect to any Subsequent
Mortgage Loan) which materially and adversely affects the interests of the
Certificateholders in such Mortgage Loan, the party discovering such breach
shall give prompt written notice to the other parties. The Trustee shall
promptly notify the Seller of such breach and request that the Seller shall,
within 90 days from the date that the Seller was notified or otherwise obtained
knowledge of such breach, either (i) cure such breach in all material respects
or (ii) purchase such Mortgage Loan from the Trust Fund at the Purchase Price
and in the manner set forth in Section 2.02; provided that if such breach 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. However, in the case of a breach
under the Mortgage Loan Purchase Agreement, subject to the approval of the
Company the Seller shall have the option to substitute a Qualified Substitute
Mortgage Loan or Loans for such Mortgage Loan if such substitution occurs within
two years following the Closing Date, except that if the breach would cause the
Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such substitution must occur within 90 days from the
date the breach was discovered if such 90 day period expires before two years
following the Closing Date. In the event that the Seller elects to substitute a
Qualified Substitute Mortgage Loan or Loans for a Deleted Mortgage Loan pursuant
to this Section 2.04, the Trustee shall enforce the obligation of the Seller
under the Mortgage Loan Purchase Agreement to deliver to the Trustee and the
Master Servicer, as appropriate, with respect to such Qualified Substitute
Mortgage Loan or Loans, the original Mortgage Note, the Mortgage, an Assignment
of the Mortgage in recordable form, and such other documents and agreements as
are required by Section 2.01, with the Mortgage Note endorsed as required by
Section 2.01. No substitution will be made in any calendar month after the
Determination Date for such month. Monthly Payments due with respect to
Qualified Substitute Mortgage Loans in the month of substitution, to the extent
received by the Master Servicer or any Sub-Servicer, shall not be part of the
Trust Fund and will be retained by the Master Servicer and remitted by the
Master Servicer to the Seller on the next succeeding Distribution Date. For the
month of substitution, distributions to Certificateholders will include the
Monthly Payment due on a Deleted Mortgage Loan for such month and thereafter the
Seller shall be entitled to retain all amounts received in respect of such
Deleted Mortgage Loan. The Company shall amend or cause to be amended the
Mortgage Loan Schedule for the benefit of the Certificateholders to reflect the
removal of such Deleted Mortgage Loan and the substitution of the Qualified
Substitute Mortgage Loan or Loans and the Company shall deliver the amended
Mortgage Loan Schedule to the Trustee. Upon such substitution, the Qualified
Substitute Mortgage Loan or Loans shall be subject to the terms of this
Agreement in

                                       62
<PAGE>

all respects, the Seller shall be deemed to have made the representations and
warranties with respect to the Qualified Substitute Mortgage Loan contained in
the Mortgage Loan Purchase Agreement as of the date of substitution, and the
Company shall be deemed to have made with respect to any Qualified Substitute
Mortgage Loan or Loans, as of the date of substitution, the representations and
warranties set forth in Exhibit I hereof (other than representations (xiv),
(xvi), (xxix) and (xxxiii) through (xli)).

         In connection with the substitution of one or more Qualified Substitute
Mortgage Loans for one or more Deleted Mortgage Loans, the Master Servicer will
determine the amount (the "Substitution Adjustment"), if any, by which the
aggregate principal balance of all such Qualified Substitute Mortgage Loans as
of the date of substitution is less than the aggregate Stated Principal Balance
of all such Deleted Mortgage Loans (in each case after application of the
principal portion of the Monthly Payments due in the month of substitution that
are to be distributed to Certificateholders in the month of substitution). The
Trustee shall enforce the obligation of the Seller under the Mortgage Loan
Purchase Agreement to provide the Master Servicer on the day of substitution for
immediate deposit into the Custodial Account the amount of such shortfall,
without any reimbursement therefor. In accordance with the Mortgage Loan
Purchase Agreement, the Seller shall give notice in writing to the Trustee of
such event, which notice shall be accompanied by an Officers' Certificate as to
the calculation of such shortfall and by an Opinion of Counsel to the effect
that such substitution will not cause (a) any federal tax to be imposed on REMIC
1, REMIC 2 or REMIC 3, including without limitation, any federal tax imposed on
"prohibited transactions" under Section 860F(a)(1) of the Code or on
"contributions after the startup date" under Section 860G(d)(1) of the Code or
(b) any portion of REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC at
any time that any Certificate is outstanding. The costs of any substitution as
described above, including any related assignments, opinions or other
documentation in connection therewith shall be borne by the Seller.

         Except as expressly set forth herein neither the Trustee nor the Master
Servicer is under any obligation to discover any breach of the above-mentioned
representations and warranties. It is understood and agreed that the obligation
of the Seller to cure such breach, purchase or to substitute for such Mortgage
Loan as to which such a breach has occurred and is continuing shall constitute
the sole remedy respecting such breach available to Certificateholders or the

Trustee's delivery on the Subsequent Transfer Dates to or upon the written order
of the Company of all or a portion of the balance of funds in the Pre-Funding

assign, set over and convey without recourse to the Trust Fund but subject to

on the Mortgage Loan Schedule attached to the related Subsequent Transfer
Instrument delivered by the Company on such Subsequent Transfer Date, (ii) all
interest accruing thereon on and after the Subsequent Cut-off Date and all
collections in respect of interest and principal due after the Subsequent Cut-
off Date and (iii) all items with respect to such Subsequent Mortgage Loans to

Mortgage Files; provided, however, that the Company reserves and retains all
right, title and interest in and to principal received and interest accruing on

transfer to the Trustee for deposit in the mortgage pool by the Company of the

the Certificateholders to constitute and to be treated as a sale of the
Subsequent Mortgage Loans by the Company to the Trust Fund. The related Mortgage

         The purchase price paid by the Trustee from amounts released from the
Pre-Funding Account shall be one-hundred percent (100%) of the aggregate Stated
Principal Balance of the Subsequent Mortgage Loans so transferred (as identified
on the Mortgage Loan Schedule provided by the Company). This Agreement shall
constitute a fixed-price purchase contract in accordance with Section
860G(a)(3)(A)(ii) of the Code.

         (b) The Company shall transfer to the Trustee for deposit in the
mortgage pool the Subsequent Mortgage Loans and the other property and rights
related thereto as described in paragraph (a) above, and the Trustee shall
release funds from the Pre-Funding Account, only upon the satisfaction of each
of the following conditions on or prior to the related Subsequent Transfer Date:

                  (i) the Company shall have provided the Trustee and the Rating
         Agencies with a timely Addition Notice and shall have provided any
         information reasonably requested by the Trustee with respect to the
         Subsequent Mortgage Loans;

                  (ii) the Company shall have delivered to the Trustee a duly

         computer file containing such Mortgage Loan Schedule to the Trustee at
         least three (3) Business Days prior to the related Subsequent Transfer
         Date;

                  (iii) as of each Subsequent Transfer Date, as evidenced by

         been rendered insolvent by such transfer nor shall

                                       65
<PAGE>

         it be aware of any pending insolvency;

                  (iv) such sale and transfer shall not result in a material
         adverse tax consequence to the Trust Fund or the Certificateholders;

                  (v) the Funding Period shall not have terminated;

                  (vi) the Company shall not have selected the Subsequent

                  (vii) the Company shall have delivered to the Trustee a
         Subsequent Transfer Instrument confirming the satisfaction of the
         conditions precedent specified in this Section 2.06 and, pursuant to
         the Subsequent Transfer Instrument, assigned to the Trustee without
         recourse for the benefit of the Certificateholders all the right, title
         and interest of the Company, in, to and under the Subsequent Mortgage
         Loan Purchase Agreement, to the extent of the Subsequent Mortgage
         Loans;

                  (viii) with respect to the last Subsequent Transfer Date, the
         Company shall have delivered to the Trustee a letter from an
         Independent accountant (with copies provided to each Rating Agency)
         stating that the characteristics of the Subsequent Mortgage Loans
         conform to the statistical characteristics set forth in paragraphs
         (c)(iii), (vi) and (ix) and (d) below; and

                  (ix) the Company shall have delivered to the Trustee an
         Opinion of Counsel addressed to the Trustee and the Rating Agencies
         with respect to the transfer of the Subsequent Mortgage Loans
         substantially in the form of the Opinion of Counsel delivered to the
         Trustee on the Closing Date regarding the true sale of the Subsequent
         Mortgage Loans.

         (c) The obligation of the Trust Fund to purchase a Subsequent Mortgage
Loan on any Subsequent Transfer Date is subject to the satisfaction of the
conditions set forth in the immediately following paragraph and the accuracy of

with a first lien on the related Mortgaged Property; (ii) no Subsequent Mortgage
Loan will have a maturity date later than April 2032; (iii) no more than
approximately 5.0% of the Subsequent Mortgage Loans will have a credit score
less than 600 and no Subsequent Mortgage Loan will have a credit score less than
544; (iv) the transfer of such Subsequent Mortgage Loans into the mortgage pool
during the Funding Period will not result in the certificates receiving lower
credit ratings from the Ratings Agencies upon termination of the Funding Period
than the ratings that were obtained at the time of the initial offering of the
Certificates; (v) such Subsequent Mortgage Loan may not be 30 or more days
delinquent as of the last day of the month preceding the Subsequent Cut-off

(ix) no Subsequent Mortgage Loan will have a first Due Date prior to September

         (d) In addition, the Subsequent Mortgage Loans will as of the

not have more than approximately 41.9% and 13.0% of such Subsequent Mortgage

one (1) Business Day prior to the Subsequent Transfer Date, each Rating Agency
shall notify the Trustee as to which Subsequent Mortgage Loans, if any, shall
not be included in the transfer on the Subsequent Transfer Date; provided,
however, that the Master Servicer, in its capacity as Originator, shall have

                          ADMINISTRATION AND SERVICING
                                OF THE TRUST FUND

         Section 3.01.     Master Servicer to Act as Master Servicer.

         The Master Servicer shall supervise, or take such actions as are
necessary to ensure, the servicing and administration of the Mortgage Loans and
any REO Property in accordance with this Agreement and its normal servicing
practices, which generally shall conform to the standards (i) of the Servicing
Guide, if Impac Funding Corporation is Master Servicer, or (ii) if Impac Funding
Corporation is not the Master Servicer, of an institution prudently servicing
mortgage loans for its own account and shall have full authority to do anything
it reasonably deems appropriate or desirable in connection with such servicing
and administration. To the extent consistent with the foregoing, the Master
Servicer shall waive (or permit a Sub-Servicer to waive) a Prepayment Charge
only under the following circumstances: (i) such waiver is standard and
customary in servicing similar Mortgage Loans and (ii) such waiver would, in the
reasonable judgement of the Master Servicer, maximize recovery of total proceeds
taking into account the value of such Prepayment Charge and the related Mortgage
Loan and, if such waiver is made in connection with a refinancing of the related
Mortgage Loan, such refinancing is related to a default or a reasonably
foreseeable default.

         The Master Servicer may perform its responsibilities relating to
servicing through other agents or independent contractors, but shall not thereby
be released from any of its responsibilities as hereinafter set forth. The
authority of the Master Servicer, in its capacity as master servicer, and any
Sub-Servicer acting on its behalf, shall include, without limitation, the power
to (i) consult with and advise any Sub-Servicer regarding administration of a
related Mortgage Loan, (ii) approve any recommendation by a Sub-Servicer to
foreclose on a related Mortgage Loan, (iii) supervise the filing and collection
of insurance claims and take or cause to be taken such actions on behalf of the
insured Person thereunder as shall be reasonably necessary to prevent the denial
of coverage thereunder, and (iv) effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing a related Mortgage Loan,
including the employment of attorneys, the institution of legal proceedings, the
collection of deficiency judgments, the acceptance of compromise proposals, the
filing of claims under any Insurance Policy and any other matter pertaining to a
delinquent Mortgage Loan. The authority of the Master Servicer shall include, in
addition, the power on behalf of the Certificateholders, the Trustee or any of
them to (i) execute and deliver customary consents or waivers and other
instruments and documents, (ii) consent to transfer of any related Mortgaged
Property and assumptions of the related Mortgage Notes and Security Instruments
(in the manner provided in this Agreement) and (iii) collect any Insurance
Proceeds and Liquidation Proceeds. Without limiting the generality of the
foregoing, the Master Servicer and any Sub-Servicer acting on its behalf may,
and is hereby authorized, and empowered by the Trustee to, execute and deliver,
on behalf of itself, the Certificateholders or the Trustee or any of them, any
instruments of satisfaction, cancellation, partial or full release, discharge
and all other comparable instruments,

                                       68
<PAGE>

with respect to the related Mortgage Loans, the Insurance Policies and the
accounts related thereto, and the Mortgaged Properties. The Master Servicer may
exercise this power in its own name or in the name of a Sub-Servicer.

         Subject to Section 3.16, the Trustee shall execute, at the written
request of the Master Servicer, and furnish to the Master Servicer and any
Sub-Servicer such documents as are necessary or appropriate to enable the Master
Servicer or any Sub-Servicer to carry out their servicing and administrative
duties hereunder, and the Trustee hereby grants to the Master Servicer a power
of attorney to carry out such duties. The Trustee shall not be liable for the
actions of the Master Servicer or any Sub-Servicers under such powers of
attorney.

         In accordance with the standards of the preceding paragraph, the Master
Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on the Mortgaged
Properties, which advances shall be reimbursable in the first instance from
related collections from the Mortgagors pursuant to Section 3.09, and further as
provided in Section 3.11; provided that the Master Servicer shall not be
obligated to make such advance if, in its good faith judgment, the Master
Servicer determines that such advance to be a Nonrecoverable Advance.

         The Master Servicer is authorized and empowered by the Trustee, on
behalf of the Certificateholders and the Trustee, in its own name or in the name
of any Subservicer, when the Master Servicer or such Subservicer, as the case
may be, believes it is appropriate in its best judgment to register any Mortgage
Loan on the MERS(R) System, or cause the removal from the registration of any
Mortgage Loan on the MERS(R) System, to execute and deliver, on behalf of the
Trustee and the Certificateholders or any of them, any and all instruments of
assignment and other comparable instruments with respect to such assignment or
re-recording of a Mortgage in the name of MERS, solely as nominee for the
Trustee and its successors and assigns. Any expenses incurred in connection with
the actions described in the preceding sentence shall be borne by the Master
Servicer in accordance with Section 3.17, with no right of reimbursement;
provided, that if, as a result of MERS discontinuing or becoming unable to
continue operations in connection with the MERS System, it becomes necessary to
remove any Mortgage Loan from registration on the MERS System and to arrange for
the assignment of the related Mortgages to the Trustee, then any related
expenses shall be reimbursable to the Master Servicer from the Trust Fund.

         Notwithstanding anything in this Agreement to the contrary, the Master
Servicer shall not (unless the Mortgagor is in default with respect to the
Mortgage Loan or such default is, in the judgment of the Master Servicer,
reasonably foreseeable) make or permit any modification, waiver or amendment of
any term of any Mortgage Loan that would both (i) effect an exchange or
reissuance of such Mortgage Loan under Section 1001 of the Code (or Treasury
regulations promulgated thereunder) and (ii) cause any of REMIC 1, REMIC 2 or
REMIC 3 to fail to qualify as a REMIC under the Code or the imposition of any
tax on "prohibited transactions" or "contributions" after the startup date under
the REMIC Provisions.

                                       69

         The relationship of the Master Servicer (and of any successor to the
Master Servicer under this Agreement) to the Trustee under this Agreement is
intended by the parties to be that of an independent contractor and not that of
a joint venturer, partner or agent.

         Section 3.02.     Sub-Servicing Agreements Between Master Servicer and
                           Sub-Servicers.

         (a) The Master Servicer may enter into Sub-Servicing Agreements with
Sub- Servicers for the servicing and administration of the Mortgage Loans and
for the performance of any and all other activities of the Master Servicer
hereunder; provided, however, that such agreements would not result in a
withdrawal or a downgrading by Standard & Poor's of its rating on any Class of
Certificates. Each Sub-Servicer shall be either (i) an institution the accounts
of which are insured by the FDIC or (ii) another entity that engages in the
business of originating or servicing mortgage loans comparable to the Mortgage
Loans, and in either case shall be authorized to transact business in the state
or states in which the related Mortgaged Properties it is to service are
situated, if and to the extent required by applicable law to enable the Sub-
Servicer to perform its obligations hereunder and under the Sub-Servicing
Agreement, and in either case shall be a Freddie Mac or Fannie Mae approved
mortgage servicer. Any Sub- Servicing Agreement entered into by the Master
Servicer shall include the provision that such Agreement may be immediately
terminated (x) with cause and without any termination fee by any Master Servicer
hereunder or (y) without cause in which case the Master Servicer shall be
responsible for any termination fee or penalty resulting therefrom. In addition,
each Sub- Servicing Agreement shall provide for servicing of the Mortgage Loans
consistent with the terms of this Agreement. With the consent of the Trustee,
the Master Servicer and the Sub-Servicers may enter into Sub-Servicing
Agreements and make amendments to the Sub-Servicing Agreements or enter into
different forms of Sub-Servicing Agreements providing for, among other things,
the delegation by the Master Servicer to a Sub-Servicer of additional duties
regarding the administration of the Mortgage Loans; provided, however, that any
such amendments or different forms shall be consistent with and not violate the
provisions of this Agreement, and that no such amendment or different form shall
be made or entered into which could be reasonably expected to be materially
adverse to the interests of the Certificateholders, without the consent of the
Holders of Certificates entitled to at least 51% of the Voting Rights. The
parties hereto acknowledge that the initial Sub-Servicer shall be Wendover.

         The Master Servicer has entered into a Sub-Servicing Agreement with
Wendover for the servicing and administration of the Mortgage Loans and may
enter into additional Sub-Servicing Agreements with Sub-Servicers acceptable to
the Trustee for the servicing and administration of certain of the Mortgage
Loans.

         (b) As part of its servicing activities hereunder, the Master Servicer,
for the benefit of the Trustee and the Certificateholders, shall enforce the
obligations of each Sub-Servicer under the related Sub-Servicing Agreement. Such
enforcement, including, without limitation, the legal prosecution of claims,
termination of Sub-Servicing Agreements and the pursuit of other appropriate
remedies, shall be in such form and carried out to such an extent and at such
time as the Master Servicer, in its good faith business judgment, would require
were it the owner of the

                                       70
<PAGE>

related Mortgage Loans. The Master Servicer shall pay the costs of such
enforcement at its own expense, but shall be reimbursed therefor only (i) from a
general recovery resulting from such enforcement only to the extent, if any,
that such recovery exceeds all amounts due in respect of the related Mortgage
Loan or (ii) from a specific recovery of costs, expenses or attorneys' fees
against the party against whom such enforcement is directed.

         (c) The Master Servicer represents that it has entered into a contract
regarding the sale of sub-servicing rights with respect to the Mortgage Loans
with GMAC and shall transfer the subservicing of the Initial Mortgage Loans from
Wendover to GMAC on or about April 1, 2002 and with respect to the Subsequent
Mortgage Loans, no later than three months after they are transferred to the
trust. The Trustee hereby consents to such transfer.

         (d) The Master Servicer represents that it will cause any Sub-Servicer
to accurately and fully report its borrower credit files to all three credit
repositories in a timely manner.

         Section 3.03.     Successor Sub-Servicers.

         The Master Servicer shall be entitled to terminate any Sub-Servicing
Agreement and the rights and obligations of any Sub-Servicer pursuant to any
Sub-Servicing Agreement in accordance with the terms and conditions of such
Sub-Servicing Agreement. In the event of termination of any Sub-Servicer, all
servicing obligations of such Sub-Servicer shall be assumed simultaneously by
the Master Servicer without any act or deed on the part of such Sub-Servicer or
the Master Servicer, and the Master Servicer either shall service directly the
related Mortgage Loans or shall enter into a Sub-Servicing Agreement with a
successor Sub-Servicer which qualifies under Section 3.02.

         Section 3.04.     Liability of the Master Servicer.

         Notwithstanding any Sub-Servicing Agreement, any of the provisions of
this Agreement relating to agreements or arrangements between the Master
Servicer and a Sub-Servicer or reference to actions taken through a Sub-Servicer
or otherwise, the Master Servicer shall under all circumstances remain obligated
and primarily liable to the Trustee and Certificateholders for the servicing and
administering of the Mortgage Loans and any REO Property in accordance with the
provisions of Article III without diminution of such obligation or liability by
virtue of such Sub-Servicing Agreements or arrangements or by virtue of
indemnification from the Sub- Servicer and to the same extent and under the same
terms and conditions as if the Master Servicer alone were servicing and
administering the Mortgage Loans. For purposes of this Agreement, the Master
Servicer shall be deemed to have received payments on Mortgage Loans when the
Sub-Servicer has received such payments. The Master Servicer shall be entitled
to enter into any agreement with a Sub-Servicer for indemnification of the
Master Servicer by such Sub-Servicer and nothing contained in this Agreement
shall be deemed to limit or modify such indemnification.

                                       71

         Section 3.05.     No Contractual Relationship Between Sub-Servicers and
                           Trustee or Certificateholders.

         Any Sub-Servicing Agreement that may be entered into and any
transactions or services relating to the Mortgage Loans involving a Sub-Servicer
in its capacity as such and not as an originator shall be deemed to be between
the Sub-Servicer and the Master Servicer alone, and the Trustee and
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Sub-Servicer
except as set forth in Section 3.06. The Master Servicer (or Sub-Servicer) shall
be liable for the payment of any franchise taxes which may be assessed by the
California Franchise Tax Board in connection with the activities of the Trust
under this Agreement.

         Section 3.06.     Assumption or Termination of Sub-Servicing Agreements
                           by Trustee.

         (a) If the Trustee or its designee shall assume the master servicing
obligations of the Master Servicer in accordance with Section 7.02 below, the
Trustee, to the extent necessary to permit the Trustee to carry out the
provisions of Section 7.02 with respect to the Mortgage Loans, shall succeed to
all of the rights and obligations of the Master Servicer under each of the Sub-
Servicing Agreements. In such event, the Trustee or its designee as the
successor master servicer shall be deemed to have assumed all of the Master
Servicer's rights and obligations therein and to have replaced the Master
Servicer as a party to such Sub-Servicing Agreements to the same extent as if
such Sub-Servicing Agreements had been assigned to the Trustee or its designee
as a successor master servicer, except that the Trustee or its designee as a
successor master servicer shall not be deemed to have assumed any obligations or
liabilities of the Master Servicer arising prior to such assumption (other than
the obligation to make any Advances hereunder) and the Master Servicer shall not
thereby be relieved of any liability or obligations under such Sub- Servicing
Agreements arising prior to such assumption. Nothing in the foregoing shall be
deemed to entitle the Trustee or its designee as a successor master servicer at
any time to receive any portion of the servicing compensation provided under
Section 3.17 except for such portion as the Master Servicer would be entitled to
receive.

         (b) In the event that the Trustee or its designee as successor master
servicer for the Trustee assumes the servicing obligations of the Master
Servicer under Section 7.02, upon the reasonable request of the Trustee or such
designee as successor master servicer the Master Servicer shall at its own
expense deliver to the Trustee, or at its written request to such designee,
photocopies of all documents, files and records, electronic or otherwise,
relating to the Sub- Servicing Agreements and the related Mortgage Loans or REO
Property then being serviced and an accounting of amounts collected and held by
it, if any, and will otherwise cooperate and use its reasonable efforts to
effect the orderly and efficient transfer of the Sub-Servicing Agreements, or
responsibilities hereunder to the Trustee, or at its written request to such
designee as successor master servicer.

         (a) The Master Servicer will coordinate and monitor remittances by
Sub-Servicers to the Master Servicer with respect to the Mortgage Loans in
accordance with this Agreement.

         (b) The Master Servicer shall make its reasonable efforts to collect or
cause to be collected all payments required under the terms and provisions of
the Mortgage Loans and shall follow, and use its reasonable efforts to cause
Sub-Servicers to follow, collection procedures comparable to the collection
procedures of prudent mortgage lenders servicing mortgage loans for their own
account to the extent such procedures shall be consistent with this Agreement.
Consistent with the foregoing, the Master Servicer may in its discretion (i)
waive or permit to be waived any late payment charge, prepayment charge,
assumption fee, or any penalty interest in connection with the prepayment of a
Mortgage Loan and (ii) suspend or reduce or permit to be suspended or reduced
regular monthly payments for a period of up to six months, or arrange or permit
an arrangement with a Mortgagor for a scheduled liquidation of delinquencies. In
the event the Master Servicer shall consent to the deferment of the due dates
for payments due on a Mortgage Note, the Master Servicer shall nonetheless make
an Advance or shall cause the related Sub-Servicer to make an advance to the
same extent as if such installment were due, owing and delinquent and had not
been deferred through liquidation of the Mortgaged Property; provided, however,
that the obligation of the Master Servicer or related Sub-Servicer to make an
Advance shall apply only to the extent that the Master Servicer believes, in
good faith, that such advances are not Nonrecoverable Advances.

         (c) On each Determination Date, with respect to each Mortgage Loan for
which during the related Prepayment Period the Master Servicer has determined
that all amounts which it expects to recover from or on account of each such
Mortgage Loan have been recovered and that no further Liquidation Proceeds will
be received in connection therewith, the Master Servicer shall provide to the
Trustee a certificate of a Servicing Officer that such Mortgage Loan became a
Liquidated Mortgage Loan in a Cash Liquidation or REO Disposition.

         The Master Servicer shall make reasonable efforts to collect all
payments called for under the terms and provisions of the Mortgage Loans, and
shall, to the extent such procedures shall be consistent with this Agreement and
the terms and provisions of any related Insurance Policy, follow such collection
procedures as it would follow with respect to mortgage loans comparable to the
Mortgage Loans and held for its own account. The Master Servicer shall not be
required to institute or join in litigation with respect to collection of any
payment (whether under a Mortgage, Mortgage Note, Primary Hazard Insurance
Policy or otherwise or against any public or governmental authority with respect
to a taking or condemnation) if it reasonably believes that it is prohibited by
applicable law from enforcing the provision of the Mortgage or other instrument
pursuant to which such payment is required. The Master Servicer shall be
responsible for preparing and distributing all information statements relating
to payments on the Mortgage Loans, in accordance with all applicable federal and
state tax laws and regulations.

         Section 3.08.     Sub-Servicing Accounts.

         In those cases where a Sub-Servicer is servicing a Mortgage Loan
pursuant to a Sub-

                                       73
<PAGE>

Servicing Agreement, the Sub-Servicer will be required to establish and maintain
one or more accounts (collectively, the "Sub-Servicing Account"). The
Sub-Servicing Account shall be an Eligible Account and shall otherwise be
acceptable to the Master Servicer. All amounts held in a Sub-Servicing Account
shall be held in trust for the Trustee for the benefit of the
Certificateholders. Any investment of funds held in such an account shall be in
Permitted Investments maturing not later than the Business Day immediately
preceding the next Sub- Servicer Remittance Date. The Sub-Servicer will be
required to deposit into the Sub-Servicing Account no later than one Business
Day after receipt all proceeds of Mortgage Loans received by the Sub-Servicer,
less its servicing compensation and any unreimbursed expenses and advances, to
the extent permitted by the Sub-Servicing Agreement. On each Sub-Servicer
Remittance Date the Sub-Servicer will be required to remit to the Master
Servicer for deposit in the Custodial Account all funds held in the
Sub-Servicing Account with respect to any Mortgage Loan as of the Sub-Servicer
Remittance Date, after deducting from such remittance an amount equal to the
servicing compensation (including interest on Permitted Investments) and
unreimbursed expenses and advances to which it is then entitled pursuant to the
related Sub-Servicing Agreement, to the extent not previously paid to or
retained by it. In addition, on each Sub- Servicer Remittance Date the
Sub-Servicer will be required to remit to the Master Servicer any amounts
required to be advanced pursuant to the related Sub-Servicing Agreement. The
Sub- Servicer will also be required to remit to the Master Servicer, within five
Business Days of receipt, the proceeds of any Principal Prepayment made by the
Mortgagor, and, on each Sub- Servicer Remittance Date, the amount of any
Insurance Proceeds or Liquidation Proceeds received during the related
Prepayment Period.

         Section 3.09.     Collection of Taxes, Assessments and Similar Items;
                           Servicing Accounts.

         The Master Servicer and the Sub-Servicers shall establish and maintain
one or more accounts (the "Servicing Accounts"), and shall deposit and retain
therein all collections from the Mortgagors (or related advances from
Sub-Servicers) for the payment of taxes, assessments, Primary Hazard Insurance
Policy premiums, and comparable items for the account of the Mortgagors, to the
extent that the Master Servicer customarily escrows for such amounts.
Withdrawals of amounts so collected from a Servicing Account may be made only to
(i) effect payment of taxes, assessments, Primary Hazard Insurance Policy
premiums and comparable items; (ii) reimburse the Master Servicer (or a
Sub-Servicer to the extent provided in the related Sub-Servicing Agreement) out
of related collections for any payments made pursuant to Sections 3.01 (with
respect to taxes and assessments), and 3.13 (with respect to Primary Hazard
Insurance Policies); (iii) refund to Mortgagors any sums as may be determined to
be overages; or (iv) clear and terminate the Servicing Account at the
termination of this Agreement pursuant to Section 9.01. As part of its servicing
duties, the Master Servicer or Sub-Servicers shall, if and to the extent
required by law, pay to the Mortgagors interest on funds in Servicing Accounts
from its or their own funds, without any reimbursement therefor.

         Section 3.10.     Custodial Account.

         (a) The Master Servicer shall establish and maintain one or more
accounts

                                       74
<PAGE>

(collectively, the "Custodial Account") in which the Master Servicer shall
deposit or cause to be deposited on a daily basis, or as and when received from
the Sub-Servicers, the following payments and collections received or made by or
on behalf of it subsequent to the Cut-off Date (or Subsequent Transfer Date,
with respect to the Subsequent Mortgage Loans), or received by it prior to the
Cut-off Date (or Subsequent Transfer Date) but allocable to a period subsequent
thereto (other than in respect of principal and interest on the Mortgage Loans
due on or before the Cut-off Date or Subsequent Transfer Date):

                  (i) all payments (including advances by a Sub-Servicer) on
account of principal, including Principal Prepayments, on the Mortgage Loans and
all Prepayment Charges collected on the Mortgage Loans (and any Master Servicer
Prepayment Charge Payment Amounts paid by, or collected on behalf of the Trust
Fund by, the Master Servicer or any Sub- Servicer);

                  (ii) all payments (including advances by a Sub-Servicer) on
account of interest on the Mortgage Loans, net of any portion thereof retained
by the Master Servicer or any Sub- Servicer as Servicing Fees;

                  (iii) all Insurance Proceeds, other than proceeds that
represent reimbursement of costs and expenses incurred by the Master Servicer or
any Sub-Servicer in connection with presenting claims under the related
Insurance Policies, Liquidation Proceeds and REO Proceeds;

                  (iv) all proceeds of any Mortgage Loan or REO Property
repurchased or purchased in accordance with Sections 2.02, 2.04 , 3.14 or 9.01;
and all amounts required to be deposited in connection with the substitution of
a Qualified Substitute Mortgage Loan pursuant to Section 2.04; and

                  (v) any amounts required to be deposited pursuant to Section
3.12, 3.13, 3.15 or 3.22.

         The foregoing requirements for deposit in the Custodial Account shall
be exclusive. In the event the Master Servicer shall deposit in the Custodial
Account any amount not required to be deposited therein, it may withdraw such
amount from the Custodial Account, any provision herein to the contrary
notwithstanding. The Custodial Account shall be maintained as a segregated
account, separate and apart from trust funds created for mortgage pass-through
certificates of other series, and the other accounts of the Master Servicer.

         (b) Funds in the Custodial Account may be invested in Permitted
Investments in accordance with the provisions set forth in Section 3.12. The
Master Servicer shall give notice to the Trustee and the Company of the location
of the Custodial Account after any change thereof.

         Section 3.11.     Permitted Withdrawals From the Custodial Account.

         The Master Servicer may, from time to time as provided herein, make
withdrawals from

                                       75
<PAGE>

the Custodial Account of amounts on deposit therein pursuant to Section 3.10
that are attributable to the Mortgage Loans for the following purposes:

         (i) to make deposits into the Certificate Account in the amounts and in
the manner provided for in Section 4.01;

         (ii) to pay to itself, the Company, the Seller or any other appropriate
person, as the case may be, with respect to each Mortgage Loan that has
previously been purchased or repurchased pursuant to Sections 2.02, 2.04, 3.14
or 9.01 all amounts received thereon and not yet distributed as of the date of
purchase or repurchase;

         (iii) to reimburse itself or any Sub-Servicer for Advances not
previously reimbursed, the Master Servicer's or any Sub-Servicer's right to
reimbursement pursuant to this clause (iii) being limited to amounts received
which represent Late Collections (net of the related Servicing Fees) of Monthly
Payments on Mortgage Loans with respect to which such Advances were made and as
further provided in Section 3.15;

         (iv) to reimburse or pay itself, the Trustee or the Company for
expenses incurred by or reimbursable to the Master Servicer, the Trustee or the
Company pursuant to Sections 3.22, 6.03, 8.05 or 10.01(g), except as otherwise
provided in such Sections hereof;

         (v) to reimburse itself or any Sub-Servicer for costs and expenses
incurred by or reimbursable to it relating to the prosecution of any claims
pursuant to Section 3.13 that are in excess of the amounts so recovered;

         (vi) to reimburse itself or any Sub-Servicer for unpaid Master
Servicing Fees, Sub- Servicing Fees and unreimbursed Servicing Advances, the
Master Servicer's or any Sub- Servicer's right to reimbursement pursuant to this
clause (vi) with respect to any Mortgage Loan being limited to late recoveries
of the payments for which such advances were made pursuant to Section 3.01 or
Section 3.09 and any other related Late Collections;

         (vii) to pay itself as servicing compensation (in addition to the
Master Servicing Fee and Sub-Servicing Fee), on or after each Distribution Date,
any interest or investment income earned on funds deposited in the Custodial
Account for the period ending on such Distribution Date;

         (viii) to reimburse itself or any Sub-Servicer for any Advance or
Servicing Advance previously made, after a Realized Loss has been allocated with
respect to the related Mortgage Loan if the Advance or Servicing Advance was not
reimbursed pursuant to clauses (iii) and (vi);

         (ix) to pay Radian the premium under the Radian Lender-Paid PMI
Policies; and

         (x) to clear and terminate the Custodial Account at the termination of
this Agreement pursuant to Section 9.01.

                                       76
<PAGE>

         The Master Servicer shall keep and maintain separate accounting records
on a Mortgage Loan by Mortgage Loan basis, for the purpose of justifying any
withdrawal from the Custodial Account pursuant to such subclauses (ii) through
(x).

         Section 3.12.     Permitted Investments.

         Any institution maintaining the Custodial Account shall at the
direction of the Master Servicer invest the funds in such account in Permitted
Investments, each of which shall mature not later than (i) the Business Day
immediately preceding the date on which such funds are required to be withdrawn
from such account pursuant to this Agreement, if a Person other than the Trustee
is the obligor thereon, and (ii) no later than the date on which such funds are
required to be withdrawn from such account pursuant to this Agreement, if the
Trustee is the obligor thereon and shall not be sold or disposed of prior to its
maturity. All income and gain realized from any such investment as well as any
interest earned on deposits in the Custodial Account shall be for the benefit of
the Master Servicer. The Master Servicer shall deposit in the Custodial Account
an amount equal to the amount of any loss incurred in respect of any such
investment immediately upon realization of such loss without right of
reimbursement.

         Section 3.13.     Maintenance of Primary Hazard Insurance.

         (a) The Master Servicer shall cause to be maintained for each Mortgage
Loan primary hazard insurance by a Qualified Insurer or other insurer
satisfactory to the Rating Agencies with extended coverage on the related
Mortgaged Property in an amount equal to the lesser of (i) 100% of the
replacement value of the improvements, as determined by the insurance company,
on such Mortgaged Property or (ii) the unpaid principal balance of the Mortgage
Loan. The Master Servicer shall also cause to be maintained on property acquired
upon foreclosure, or deed in lieu of foreclosure, of any Mortgage Loan, fire
insurance with extended coverage in an amount equal to the replacement value of
the improvements thereon. Any costs incurred in maintaining any insurance
described in this Section 3.13 (other than any deductible described in the last
paragraph hereof) shall be recoverable as a Servicing Advance. The Master
Servicer shall not be obligated to advance any amounts pursuant to this Section
3.13 if, in its good faith judgment, the Master Servicer determines that such
advance would be a Nonrecoverable Advance. Pursuant to Section 3.10, any amounts
collected by the Master Servicer under any such policies (other than amounts to
be applied to the restoration or repair of the related Mortgaged Property or
property thus acquired or amounts released to the Mortgagor in accordance with
the Master Servicer's normal servicing procedures) shall be deposited in the
Custodial Account, subject to withdrawal pursuant to Section 3.11. Any cost
incurred by the Master Servicer in maintaining any such insurance shall not, for
the purpose of calculating monthly distributions to Certificateholders, be added
to the amount owing under the Mortgage Loan, notwithstanding that the terms of
the Mortgage Loan so permit. It is understood and agreed that no earthquake or
other additional insurance is to be required of any Mortgagor or maintained on
property acquired in respect of a Mortgage Loan other than pursuant to such
applicable laws and regulations as shall at any time be in force and as shall
require such additional insurance.

                                       77
<PAGE>

         The Master Servicer shall, or shall cause the related Sub-Servicer to,
exercise its best reasonable efforts to maintain and keep in full force and
effect each Primary Insurance Policy by a Qualified Insurer, or other insurer
satisfactory to the Rating Agencies, with respect to each first lien Mortgage
Loan as to which as of the Cut-Off Date (or Subsequent Transfer Date, with
respect to the Subsequent Mortgage Loans) such a Primary Insurance Policy was in
effect (or, in the case of a Qualified Substitute Mortgage Loan, the date of
substitution) and the original principal amount of the related Mortgage Note
exceeded 80% of the Collateral Value in an amount at least equal to the excess
of such original principal amount over 75% of such Collateral Value until the
principal amount of any such first lien Mortgage Loan is reduced below 80% of
the Collateral Value or, based upon a new appraisal, the principal amount of
such first lien Mortgage Loan represents less than 80% of the new appraised
value. The Master Servicer shall, or shall cause the related Sub-Servicer to,
effect the timely payment of the premium on each Primary Insurance Policy. The
Master Servicer and the related Sub-Servicer shall have the power to substitute
for any Primary Insurance Policy another substantially equivalent policy issued
by another Qualified Insurer, provided, that, such substitution shall be subject
to the condition that it will not cause the ratings on the Certificates to be
downgraded or withdrawn, as evidenced in writing from each Rating Agency.

         The Master Servicer shall cooperate with Radian and shall use its best
efforts to furnish all reasonable aid, evidence and information in the
possession of the Master Servicer or to which the Master Servicer has access
with respect to any Radian Insured Loan.

         The Master Servicer shall cooperate with Radian and shall use its best
efforts to furnish all reasonable aid, evidence and information in the
possession of the Master Servicer or to which the Master Servicer has access
with respect to any Radian Insured Loan.

         In the event of a default by Radian under the Radian Lender-Paid PMI
Policy (a "Replacement Event"), the Master Servicer shall use its best efforts
to obtain a substitute lender- paid primary mortgage insurance policy (a
"Substitute PMI Policy"); provided, however, that the Master Servicer shall not
be obligated, and shall have no liability for failing, to obtain a Substitute
PMI Policy unless such Substitute PMI Policy can be obtained on the following
terms and conditions: (i) the Certificates shall be rated no lower than the
rating assigned by each Rating Agency to the Certificates immediately prior to
such Replacement Event, as evidenced by a letter from each Rating Agency
addressed to the Company, the Master Servicer and the Trustee, (ii) the timing
and mechanism for drawing on such new Substitute PMI Policy shall be reasonably
acceptable to the Master Servicer and the Trustee and (iii) the premiums under
the proposed Substitute PMI Policy shall not exceed such premiums under the
existing Radian Lender-Paid PMI Policy.

         With respect to the Radian PMI Insured Loans covered by a Radian
Lender-Paid PMI Policy, the Master Servicer will confirm with Radian, and Radian
will certify to the Trustee, on or before February 15, 2002, that the Mortgage
Loans indicated on the Mortgage Loan Schedule as being covered by Radian
Lender-Paid PMI Policy are so covered.

                                       78
<PAGE>

         No earthquake or other additional insurance is to be required of any
Mortgagor or maintained on property acquired with respect to a security
instrument other than pursuant to such applicable laws and regulations as shall
at any time be in force and shall require such additional insurance. When, at
the time of origination of the Mortgage Loan or at any subsequent time, the
Mortgaged Property is located in a federally designated special flood hazard
area, the Master Servicer shall cause with respect to the Mortgage Loans and
each REO Property flood insurance (to the extent available and in accordance
with mortgage servicing industry practice) to be maintained. Such flood
insurance shall cover the Mortgaged Property, including all items taken into
account in arriving at the Collateral Value on which the Mortgage Loan was
based, and shall be in an amount equal to the lesser of (i) the Stated Principal
Balance of the related Mortgage Loan and (ii) the minimum amount required under
the terms of coverage to compensate for any damage or loss on a replacement cost
basis, but not more than the maximum amount of such insurance available for the
related Mortgaged Property under either the regular or emergency programs of the
National Flood Insurance Program (assuming that the area in which such Mortgaged
Property is located is participating in such program). Unless applicable state
law requires a higher deductible, the deductible on such flood insurance may not
exceed $1,000 or 1% of the applicable amount of coverage, whichever is less.

         In the event that the Master Servicer shall obtain and maintain a
blanket fire insurance policy with extended coverage insuring against hazard
losses on all of the Mortgage Loans, it shall conclusively be deemed to have
satisfied its obligations as set forth in the first two sentences of this
Section 3.13, it being understood and agreed that such policy may contain a
deductible clause, in which case the Master Servicer shall, in the event that
there shall not have been maintained on the related Mortgaged Property a policy
complying with the first two sentences of this Section 3.13 and there shall have
been a loss which would have been covered by such policy, deposit in the
Certificate Account from its own funds the amount not otherwise payable under
the blanket policy because of such deductible clause. Any such deposit by the
Master Servicer shall be made on the Certificate Account Deposit Date next
preceding the Distribution Date which occurs in the month following the month in
which payments under any such policy would have been deposited in the Custodial
Account. Any such deposit shall not be deemed Servicing Advances and the Master
Servicer shall not be entitled to reimbursement therefor. In connection with its
activities as administrator and servicer of the Mortgage Loans, the Master
Servicer agrees to present, on behalf of itself, the Trustee and
Certificateholders, claims under any such blanket policy.

         Section 3.14.     Enforcement of Due-on-Sale Clauses; Assumption
                           Agreements.

         The Master Servicer will, to the extent it has knowledge of any
conveyance or prospective conveyance by any Mortgagor of the Mortgaged Property
(whether by absolute conveyance or by contract of sale, and whether or not the
Mortgagor remains or is to remain liable under the Mortgage Note or the
Mortgage), exercise or cause to be exercised its rights to accelerate the
maturity of such Mortgage Loan under any "due-on-sale" clause applicable
thereto; provided, however, that the Master Servicer shall not exercise any such
rights if it reasonably believes that it is prohibited by law from doing so. The
Master Servicer or the related Sub-Servicer may

                                       79
<PAGE>

repurchase a Mortgage Loan at the Purchase Price when the Master Servicer
requires acceleration of the Mortgage Loan, but only if the Master Servicer is
satisfied, as evidenced by an Officer's Certificate delivered to the Trustee,
that either (i) such Mortgage Loan is in default or default is reasonably
foreseeable or (ii) if such Mortgage Loan is not in default or default is not
reasonably foreseeable, such repurchase will have no adverse tax consequences
for the Trust Fund or any Certificateholder. If the Master Servicer is unable to
enforce such "due-on-sale" clause (as provided in the second preceding sentence)
or if no "due-on-sale" clause is applicable, the Master Servicer or the
Sub-Servicer is authorized to enter into an assumption and modification
agreement with the Person to whom such property has been conveyed or is proposed
to be conveyed, pursuant to which such Person becomes liable under the Mortgage
Note and, to the extent permitted by applicable state law, the Mortgagor remains
liable thereon; provided, however, that the Master Servicer shall not enter into
any assumption and modification agreement if the coverage provided under the
Primary Insurance Policy, if any, would be impaired by doing so. The Master
Servicer shall notify the Trustee, whenever possible, before the completion of
such assumption agreement, and shall forward to the Trustee the original copy of
such assumption agreement, which copy shall be added by the Trustee to the
related Mortgage File and which shall, for all purposes, be considered a part of
such Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. In connection with any such assumption agreement,
the interest rate on the related Mortgage Loan shall not be changed and no other
material alterations in the Mortgage Loan shall be made unless such material
alteration would not cause any of REMIC 1, REMIC 2 or REMIC 3 to fail to qualify
as a REMIC for federal income tax purposes, as evidenced by an Opinion of
Counsel. The Master Servicer is also authorized to enter into a substitution of
liability agreement with such Person, pursuant to which the original Mortgagor
is released from liability and such Person is substituted as the Mortgagor and
becomes liable under the Mortgage Note. Any fee collected by or on behalf of the
Master Servicer for entering into an assumption or substitution of liability
agreement will be retained by or on behalf of the Master Servicer as additional
servicing compensation. In connection with any such assumption, no material term
of the Mortgage Note (including but not limited to the Mortgage Rate, the amount
of the Monthly Payment and any other term affecting the amount or timing of
payment on the Mortgage Loan) may be changed. The Master Servicer shall not
enter into any substitution or assumption if such substitution or assumption
shall (i) both constitute a "significant modification" effecting an exchange or
reissuance of such Mortgage Loan under the Code (or Treasury regulations
promulgated thereunder) and cause any of REMIC 1, REMIC 2 or REMIC 3 to fail to
qualify as a REMIC under the REMIC Provisions or (ii) cause the imposition of
any tax on "prohibited transactions" or "contributions" after the Startup Day
under the REMIC Provisions. The Master Servicer shall notify the Trustee that
any such substitution or assumption agreement has been completed by forwarding
to the Trustee the original copy of such substitution or assumption agreement,
which copy shall be added to the related Mortgage File and shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof. A portion equal to
up to 2% of the Collateral Value of the related Mortgage Loan, of any fee or
additional interest collected by the related Sub-Servicer for consenting in any
such conveyance or entering into any such assumption agreement may be retained
by the related Sub-Servicer as additional servicing compensation.

                                       80
<PAGE>

         Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Master Servicer shall not be deemed to be in default, breach or
any other violation of its obligations hereunder by reason of any assumption of
a Mortgage Loan by operation of law or any assumption that the Master Servicer
may be restricted by law from preventing, for any reason whatsoever. For
purposes of this Section 3.14, the term "assumption" is deemed to also include a
sale of a Mortgaged Property that is not accompanied by an assumption or
substitution of liability agreement.

         Section 3.15.     Realization Upon Defaulted Mortgage Loans.

         The Master Servicer shall exercise reasonable efforts, consistent with
the procedures that the Master Servicer would use in servicing loans for its own
account, to foreclose upon or otherwise comparably convert (which may include an
REO Acquisition) the ownership of properties securing such of the Mortgage Loans
as come into and continue in default and as to which no satisfactory
arrangements can be made for collection of delinquent payments pursuant to
Section 3.07, and which are not released from the Trust Fund pursuant to any
other provision hereof. The Master Servicer shall use reasonable efforts to
realize proceeds from such defaulted Mortgage Loans in such manner (including
short sales) as will maximize the receipt of principal and interest by
Certificateholders, taking into account, among other things, the timing of
foreclosure proceedings. The foregoing is subject to the provisions that, in any
case in which Mortgaged Property shall have suffered damage from an Uninsured
Cause, the Master Servicer shall not be required to expend its own funds toward
the restoration of such property unless it shall determine in its sole
discretion (i) that such restoration will increase the net proceeds of
liquidation of the related Mortgage Loan to Certificateholders after
reimbursement to itself for such expenses, and (ii) that such expenses will be
recoverable by the Master Servicer through Insurance Proceeds or Liquidation
Proceeds from the related Mortgaged Property, as contemplated in Section 3.11.
The Master Servicer shall be responsible for all other costs and expenses
incurred by it in any such proceedings; provided, however, that it shall be
entitled to reimbursement thereof from the related property, as contemplated in
Section 3.11.

         The proceeds of any Cash Liquidation or REO Disposition, as well as any
recovery resulting from a partial collection of Insurance Proceeds or
Liquidation Proceeds or any income from an REO Property, will be deposited into
the Custodial Account and applied in the following order of priority: first, to
reimburse the Master Servicer or any Sub-Servicer for any related unreimbursed
Servicing Advances, pursuant to Section 3.11(vi) or 3.22; second, to accrued and
unpaid interest on the Mortgage Loan or REO Imputed Interest, at the Mortgage
Rate, to the date of the Cash Liquidation or REO Disposition, or to the Due Date
prior to the Distribution Date on which such amounts are to be distributed if
not in connection with a Cash Liquidation or REO Disposition; and third, as a
recovery of principal of the Mortgage Loan. If the amount of the recovery so
allocated to interest is less than a full recovery thereof, that amount will be
allocated as follows: first, to unpaid Servicing Fees; and second, to interest
at the Net Mortgage Rate. The portion of the recovery so allocated to unpaid
Servicing Fees shall be reimbursed to the Master Servicer or any Sub-Servicer
pursuant to Section 3.11(vi). The portions of the recovery so allocated to
interest at the Net Mortgage Rate and to principal of the Mortgage Loan shall be

                                       81
<PAGE>

applied as follows: first, to reimburse the Master Servicer or any Sub-Servicer
for any related unreimbursed Advances in accordance with Section 3.11(iii) or
3.22, second, payment to Radian in accordance with Sections 3.11(ix) and third,
for payment to the Trustee and distribution to the Certificateholders in
accordance with the provisions of Section 4.01, subject to Section 3.22 with
respect to certain recoveries from an REO Disposition constituting Excess
Proceeds.

         Section 3.16.     Trustee to Cooperate; Release of Mortgage Files.

         Upon the payment in full of any Mortgage Loan, or the receipt by the
Master Servicer of a notification that payment in full shall be escrowed in a
manner customary for such purposes, the Master Servicer will immediately notify
the Trustee by a certification (which certification shall include a statement to
the effect that all amounts received or to be received in connection with such
payment which are required to be deposited in the Custodial Account pursuant to
Section 3.10 have been or will be so deposited) of a Servicing Officer and shall
request delivery to it of the Mortgage File in the form of the Request for
Release attached hereto as Exhibit F-2. Upon receipt of such certification and
request, the Trustee shall promptly release the related Mortgage File to the
Master Servicer. Subject to the receipt by the Master Servicer of the proceeds
of such payment in full and the payment of all related fees and expenses, the
Master Servicer shall arrange for the release to the Mortgagor of the original
canceled Mortgage Note. In connection with the satisfaction of any MOM Loan, the
Master Servicer is authorized to cause the removal from the registration on the
MERS(R) System of such Mortgage. All other documents in the Mortgage File shall
be retained by the Master Servicer to the extent required by applicable law. The
Master Servicer shall provide for preparation of the appropriate instrument of
satisfaction covering any Mortgage Loan which pays in full and the Trustee shall
cooperate in the execution and return of such instrument to provide for its
delivery or recording as may be required. No expenses incurred in connection
with any instrument of satisfaction or deed of reconveyance shall be chargeable
to the Custodial Account or the Certificate Account.

         From time to time and as appropriate for the servicing or foreclosure
of any Mortgage Loan, including, for this purpose, collection under any
insurance policy relating to the Mortgage Loan, the Trustee shall, upon request
of the Master Servicer and delivery to the Trustee of a Request for Release in
the form attached hereto as Exhibit F-1, release the related Mortgage File to
the Master Servicer and the Trustee shall execute such documents as the Master
Servicer shall prepare and request as being necessary to the prosecution of any
such proceedings. Such Request for Release shall obligate the Master Servicer to
return each document previously requested from the Mortgage File to the Trustee
when the need therefor by the Master Servicer no longer exists; and in any event
within 21 days of the Master Servicer's receipt thereof, unless the Mortgage
Loan has been liquidated and the Liquidation Proceeds relating to the Mortgage
Loan have been deposited in the Custodial Account or the Mortgage File or such
document has been delivered to an attorney, or to a public trustee or other
public official as required by law, for purposes of initiating or pursuing legal
action or other proceedings for the foreclosure of the Mortgaged Property either
judicially or non-judicially, and the Master Servicer has delivered to the
Trustee a

                                       82
<PAGE>

certificate of a Servicing Officer certifying as to the name and address of the
Person to which such Mortgage File or such document was delivered and the
purpose or purposes of such delivery. Upon receipt of a Request for Release
stating that such Mortgage Loan was liquidated and that all amounts received or
to be received in connection with such liquidation which are required to be
deposited into the Custodial Account have been or will be so deposited, or that
such Mortgage Loan has become an REO Property, a copy of the Request for Release
shall be released by the Trustee to the Master Servicer.

         Upon written request of a Servicing Officer, the Trustee shall execute
and deliver to the Master Servicer any court pleadings, requests for trustee's
sale or other documents prepared by the Master Servicer that are necessary to
the foreclosure or trustee's sale in respect of a Mortgaged Property or to any
legal action brought to obtain judgment against any Mortgagor on the Mortgage
Note or Mortgage or to obtain a deficiency judgment, or to enforce any other
remedies or rights provided by the Mortgage Note or Mortgage or otherwise
available at law or in equity. Each such request that such pleadings or
documents be executed by the Trustee shall include a certification signed by a
Servicing Officer as to the reason such documents or pleadings are required and
that the execution and delivery thereof by the Trustee will not invalidate or
otherwise affect the lien of the Mortgage, except for the termination of such a
lien upon completion of the foreclosure or trustee's sale.

         Section 3.17.     Servicing Compensation.

         As compensation for its activities hereunder, the Master Servicer shall
be entitled to withhold and retain, from deposits to the Custodial Account of
amounts representing payments or recoveries of interest, the Servicing Fees with
respect to each Mortgage Loan (less any portion of such amounts retained by any
Sub-Servicer). In addition, the Master Servicer shall be entitled to recover
unpaid Servicing Fees out of related Late Collections to the extent permitted in
Section 3.11.

         Each Sub-Servicing Agreement shall permit the related Sub-Servicer to
retain the Sub- Servicer Fees from collections on the related Mortgage Loans, or
shall provide that the Sub- Servicer be paid directly by the Master Servicer
from collections on the related Mortgage Loans. To the extent the Master
Servicer directly services a Mortgage Loan, the Master Servicer shall be
entitled to retain the Sub-Servicing Fees for that Mortgage Loan.

         The Master Servicer also shall be entitled pursuant to Section 3.11 to
receive from the Custodial Account as additional servicing compensation interest
or other income earned on deposits therein, subject to Section 3.23, as well as
any assumption fees, late payment charges and reconveyance fees. The Master
Servicer shall not be entitled to retain any Prepayment Charges. The Master
Servicer shall be required to pay all expenses incurred by it in connection with
its servicing activities hereunder (including payment of the premiums for any
blanket policy insuring against hazard losses pursuant to Section 3.13 and
servicing compensation of the Sub- Servicer to the extent not retained by it),
and shall not be entitled to reimbursement therefor except as specifically
provided in Section 3.11. The Master Servicing Fee may not be

                                       83
<PAGE>

transformed in whole or in part except in connection with the transfer of all of
the Master Servicer's responsibilities and obligations under this Agreement.

         The Master Servicer also shall be entitled pursuant to Section 3.11 to
receive from the Custodial Account as additional servicing compensation interest
or other income earned on deposits therein, subject to Section 3.23, as well as
any assumption fees, late payment charges and reconveyance fees. The Master
Servicer shall not be entitled to retain any Prepayment Charges. The Master
Servicer shall be required to pay all expenses incurred by it in connection with
its servicing activities hereunder (including payment of the premiums for any
blanket policy insuring against hazard losses pursuant to Section 3.13 and
servicing compensation of the Sub- Servicer to the extent not retained by it),
and shall not be entitled to reimbursement therefor except as specifically
provided in Section 3.11. The Servicing Fee may not be transferred in whole or
in part except in connection with the transfer of all of the Master Servicer's
responsibilities and obligations under this Agreement.

         Section 3.18.     Maintenance of Certain Servicing Policies.

         The Master Servicer shall obtain and maintain at its own expense and
shall cause each Sub-Servicer to obtain and maintain for the duration of this
Agreement a blanket fidelity bond and an errors and omissions insurance policy
covering the Master Servicer's and such Sub- Servicer's officers, employees and
other persons acting on its behalf in connection with its activities under this
Agreement. The amount of coverage shall be at least equal to the coverage
maintained by the Master Servicer or Sub-Servicer in order to be acceptable to
Fannie Mae or Freddie Mac to service loans for it or otherwise in an amount as
is commercially available at a cost that is generally not regarded as excessive
by industry standards. The Master Servicer shall promptly notify the Trustee in
writing of any material change in the terms of such bond or policy. The Master
Servicer shall provide annually to the Trustee a certificate of insurance that
such bond and policy are in effect. If any such bond or policy ceases to be in
effect, the Master Servicer shall, to the extent possible, give the Trustee ten
days' notice prior to any such cessation and shall use its reasonable best
efforts to obtain a comparable replacement bond or policy, as the case may be.

         Section 3.19.     Annual Statement as to Compliance.

         Within 120 days after December 31 of each year, commencing on the first
December 31 following the first anniversary of the Closing Date, the Master
Servicer at its own expense shall deliver to the Trustee, with a copy to the
Rating Agencies, a certificate signed by a Servicing Officer stating, as to the
signers thereof, that (i) a review of the activities of the Master Servicer
during the preceding calendar year and of performance under this Agreement has
been made under such officers' supervision, (ii) to the best of such officers'
knowledge, based on such review, the Master Servicer has fulfilled all its
obligations under this Agreement for such year, or, if there has been a default
in the fulfillment of any such obligation, specifying each such default known to
such officer and the nature and status thereof including the steps being taken
by the Master Servicer to remedy such default; (iii) a review of the activities
of each Sub-Servicer

                                       84
<PAGE>

during the Sub-Servicer's most recently ended fiscal year on or prior to such
December 31 and its performance under its Sub-Servicing Agreement has been made
under such officer's supervision; and (iv) to the best of the Servicing
Officer's knowledge, based on his review and the certification of an officer of
the Sub-Servicer (unless the Servicing Officer has reason to believe that
reliance on such certification is not justified), either each Sub-Servicer has
performed and fulfilled its duties, responsibilities and obligations under this
Agreement and its Sub-Servicing Agreement in all material respects throughout
the year, or, if there has been a default in performance or fulfillment of any
such duties, responsibilities or obligations, specifying the nature and status
of each such default known to the Servicing Officer. Copies of such statements
shall be provided by the Master Servicer to the Certificateholders upon request
or by the Trustee at the expense of the Master Servicer should the Master
Servicer fail to provide such copies.

         Section 3.20.     Annual Independent Public Accountants' Servicing
                           Statement.

         (a) Within 120 days after December 31 of each year, commencing on the
first December 31 following the first anniversary of the Closing Date, the
Master Servicer, at its expense, shall cause a firm of independent public
accountants who are members of the American Institute of Certified Public
Accountants to furnish a statement to the Master Servicer, which will be
provided to the Trustee and the Rating Agencies, to the effect that, in
connection with the firm's examination of the Master Servicer's financial
statements as of the end of such calendar year, nothing came to their attention
that indicated that the Master Servicer was not in compliance with the
provisions of this Agreement except for (i) such exceptions as such firm
believes to be immaterial and (ii) such other exceptions as are set forth in
such statement.

         (b) Within 120 days after December 31 of each year, commencing December
2002, the Master Servicer, at its expense, shall or shall cause each
Sub-Servicer to cause a nationally recognized firm of independent certified
public accountants to furnish to the Master Servicer or such Sub-Servicer a
report stating that (i) it has obtained a letter of representation regarding
certain matters from the management of the Master Servicer or such Sub-Servicer
which includes an assertion that the Master Servicer or such Sub-Servicer has
complied with certain minimum mortgage loan servicing standards (to the extent
applicable to commercial and multifamily mortgage loans) identified in the
Uniform Single Attestation Program for Mortgage Bankers established by the
Mortgage Bankers Association of America with respect to the servicing of first
and second lien conventional single family mortgage loans during the most
recently completed calendar year and (ii) on the basis of an examination
conducted by such firm in accordance with standards established by the American
Institute of Certified Public Accountants, such representation is fairly stated
in all material respects, subject to such exceptions and other qualifications
that may be appropriate. Immediately upon receipt of such report, the Master
Servicer shall or shall cause each Sub-Servicer to furnish a copy of such report
to the Trustee and the Rating Agencies.

         Section 3.21.     Access to Certain Documentation.

         The Master Servicer shall provide, and shall cause any Sub-Servicer to
provide, to the

                                       85
<PAGE>

Trustee, access to the documentation in their possession regarding the related
Mortgage Loans and REO Properties and to the Certificateholders, the FDIC, and
the supervisory agents and examiners of the FDIC (to which the Trustee shall
also provide) access to the documentation regarding the related Mortgage Loans
required by applicable regulations, such access being afforded without charge
but only upon reasonable request and during normal business hours at the offices
of the Master Servicer or the Sub-Servicers that are designated by these
entities; provided, however, that, unless otherwise required by law, the
Trustee, the Master Servicer or the Sub-Servicer shall not be required to
provide access to such documentation if the provision thereof would violate the
legal right to privacy of any Mortgagor; provided, further, however, that the
Trustee shall coordinate its requests for such access so as not to impose an
unreasonable burden on, or cause an unreasonable interruption of, the business
of the Master Servicer or any Sub-Servicer. The Master Servicer, the
Sub-Servicers and the Trustee shall allow representatives of the above entities
to photocopy any of the documentation and shall provide equipment for that
purpose at a charge that covers their own actual out-of-pocket costs.

         Section 3.22.     Title, Conservation and Disposition of REO Property.

         This Section shall apply only to REO Properties acquired for the
account of REMIC 1 and shall not apply to any REO Property relating to a
Mortgage Loan which was purchased or repurchased from REMIC 1 pursuant to
Sections 2.02, 2.04 or 3.14. In the event that title to any such REO Property is
acquired, the deed or certificate of sale shall be issued to the Trustee, or to
its nominee, on behalf of the Certificateholders. The Master Servicer, on behalf
of REMIC 1, shall either sell any REO Property before the close of the third
taxable year following the taxable year in which REMIC 1 acquires ownership of
such REO Property for purposes of Section 860G(a)(8) of the Code or, at the
expense of REMIC 1, request, more than 60 days before the day on which the
three-year grace period would otherwise expire an extension of the three-year
grace period, unless the Master Servicer has delivered to the Trustee an Opinion
of Counsel (which shall not be at the expense of the Trustee), addressed to the
Trustee and the Master Servicer, to the effect that the holding by REMIC 1 of
such REO Property subsequent to the close of the third taxable year following
the taxable year in which REMIC 1 acquires ownership of such REO Property will
not result in the imposition on REMIC 1 of taxes on "prohibited transactions"
thereof, as defined in Section 860F of the Code, or cause any of REMIC 1, REMIC
2 or REMIC 3 to fail to qualify as a REMIC under the REMIC Provisions or
comparable provisions of the laws of the State of California at any time that
any Certificates are outstanding. The Master Servicer shall manage, conserve,
protect and operate each REO Property for the Certificateholders solely for the
purpose of its prompt disposition and sale in a manner which does not cause such
REO Property to fail to qualify as "foreclosure property" within the meaning of
Section 860G(a)(8) or result in the receipt by any of REMIC 1, REMIC 2 or REMIC
3 of any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code or any "net income from foreclosure property" which is
subject to taxation under the REMIC Provisions. Pursuant to its efforts to sell
such REO Property, the Master Servicer shall either itself or through an agent
selected by the Master Servicer protect and conserve such REO Property in the
same manner and to such extent as is customary in the locality where such REO
Property is located and may, incident to its conservation and protection of the
interests of the

                                       86
<PAGE>

Certificateholders, rent the same, or any part thereof, as the Master Servicer
deems to be in the best interest of the Certificateholders for the period prior
to the sale of such REO Property.

         Any REO Disposition shall be for cash only (unless changes in the REMIC
Provisions made subsequent to the Startup Day allow a sale for other
consideration).

         The Master Servicer shall segregate and hold all funds collected and
received in connection with the operation of any REO Property separate and apart
from its own funds and general assets. The Master Servicer shall deposit, or
cause to be deposited, on a daily basis in the Custodial Account all revenues
received with respect to the REO Properties, net of any directly related
expenses incurred or withdraw therefrom funds necessary for the proper
operation, management and maintenance of the REO Property.

         If as of the date of acquisition of title to any REO Property there
remain outstanding unreimbursed Servicing Advances with respect to such REO
Property or any outstanding Advances allocated thereto the Master Servicer, upon
an REO Disposition, shall be entitled to reimbursement for any related
unreimbursed Servicing Advances and any unreimbursed related Advances as well as
any unpaid Servicing Fees from proceeds received in connection with the REO
Disposition, as further provided in Section 3.15. The Master Servicer shall not
be obligated to advance any amounts with respect to an REO Property if, in its
good faith judgment, the Master Servicer determines that such advance would
constitute a Nonrecoverable Advance.

         The REO Disposition shall be carried out by the Master Servicer at such
price and upon such terms and conditions as the Master Servicer shall determine.

         The Master Servicer shall deposit the proceeds from the REO
Disposition, net of any payment to the Master Servicer as provided above, in the
Custodial Account upon receipt thereof for distribution in accordance with
Section 4.01; provided, that any such net proceeds received by the Master
Servicer which are in excess of the applicable Stated Principal Balance plus all
unpaid REO Imputed Interest thereon through the last day of the month in which
the REO Disposition occurred ("Excess Proceeds") shall be retained by the Master
Servicer as additional servicing compensation.

         With respect to any Mortgage Loan as to which the Master Servicer has
received notice of, or has actual knowledge of, the presence of any toxic or
hazardous substance on the Mortgaged Property, the Master Servicer shall not, on
behalf of the Trustee, either (i) obtain title to the related Mortgaged Property
as a result of or in lieu of foreclosure or otherwise, or (ii) otherwise acquire
possession of, the related Mortgaged Property, unless the Master Servicer has,
at least 30 days prior to taking such action, obtained and delivered to the
Trustee an environmental audit report prepared by a Person who regularly
conducts environmental audits using customary industry standards. The Master
Servicer shall take such action as it deems to be in the best economic interest
of the Trust Fund (other than proceeding against the Mortgaged Property) and is
hereby authorized at such time as it deems appropriate to release such Mortgaged
Property from the lien of the related Mortgage.

                                       87
<PAGE>

         The cost of the environmental audit report contemplated by this Section
3.22 shall be advanced by the Master Servicer as an expense of the Trust Fund,
and the Master Servicer shall be reimbursed therefor from the Custodial Account
as provided in Section 3.11, any such right of reimbursement being prior to the
rights of the Certificateholders to receive any amount in the Custodial Account.

         If the Master Servicer determines, as described above, that it is in
the best economic interest of the Trust Fund to take such actions as are
necessary to bring any such Mortgaged Property in compliance with applicable
environmental laws, or to take such action with respect to the containment,
clean-up or remediation of hazardous substances, hazardous materials, hazardous
wastes, or petroleum-based materials affecting any such Mortgaged Property, then
the Master Servicer shall take such action as it deems to be in the best
economic interest of the Trust Fund. The cost of any such compliance,
containment, clean-up or remediation shall be advanced by the Master Servicer as
an expense of the Trust Fund, and the Master Servicer shall be entitled to be
reimbursed therefor from the Custodial Account as provided in Section 3.11, any
such right of reimbursement being prior to the rights of the Certificateholders
to receive any amount in the Custodial Account.

         Section 3.23.     Additional Obligations of the Master Servicer.

         On each Certificate Account Deposit Date, the Master Servicer shall
deliver to the Trustee for deposit in the Certificate Account from its own funds
and without any right of reimbursement therefor, a total amount equal to the
amount of Compensating Interest for the related Distribution Date.

         Section 3.24.     Additional Obligations of the Company.

         The Company agrees that on or prior to the tenth day after the Closing
Date, the Company shall provide the Trustee with a written notification,
substantially in the form of Exhibit J attached hereto, relating to each Class
of Certificates, setting forth (i) in the case of each Class of such
Certificates, (a) if less than 10% of the aggregate Certificate Principal
Balance or Notional Amount of such Class of Certificates has been sold as of
such date, the value calculated pursuant to clause (b)(iii) of Exhibit J hereto,
or, (b) if 10% or more of such Class of Certificates has been sold as of such
date but no single price is paid for at least 10% of the aggregate Certificate
Principal Balance or Notional Amount of such Class of Certificates, then the
weighted average price at which the Certificates of such Class were sold and the
aggregate percentage of Certificates of such Class sold, (c) the first single
price at which at least 10% of the aggregate Certificate Principal Balance or
Notional Amount of such Class of Certificates was sold, or (d) if any
Certificates of each Class of Certificates are retained by the Company or an
affiliate corporation, or are delivered to the Seller, the fair market value of
such Certificates as of the Closing Date, (ii) the Prepayment Assumption used in
pricing the Certificates, and (iii) such other information as to matters of fact
as the Trustee may reasonably request to enable it to comply with its reporting
requirements with respect to each Class of such Certificates to the extent such
information can in the good faith judgment of the Company be determined by it.

         Section 3.25.     Periodic Filings with the Securities and Exchange
                           Commission; Additional Information.

         The Trustee shall prepare or cause to be prepared for filing with the
Commission any and all reports, statements and information respecting the Trust
Fund and/or the Certificates required to be filed with the Commission pursuant
to the Securities Exchange Act of 1934, as amended, and shall solicit any and
all proxies of the Certificateholders whenever such proxies are required to be
solicited, pursuant to the Securities Exchange Act of 1934, as amended. The
Company shall promptly file, and exercise its reasonable best efforts to obtain
a favorable response to, no- action requests with, or other appropriate
exemptive relief from, the Commission seeking the usual and customary exemption
from such reporting requirements granted to issuers of securities similar to the
Certificates. Fees and expenses incurred by the Trustee in connection with this
Section shall not be reimbursable from the Trust Fund.

         The Master Servicer and the Company each agree to promptly furnish to
the Trustee, from time to time upon request, such further information, reports
and financial statements within their respective control related to this
Agreement and the Mortgage Loans as the Trustee reasonably deems appropriate to
prepare and file all necessary reports with the Commission.

following the date of such investment and shall not be sold or disposed of prior

the benefit of the Master Servicer and shall be subject to its withdrawal or
order from time to time. The amount of any losses incurred in respect of any
such investments shall be deposited in the

                                       94
<PAGE>

realized without any right of reimbursement.

         (h) Except as otherwise provided in Section 9.01, if the Master
Servicer anticipates that a final distribution with respect to any Class of
Certificates will be made on the next Distribution Date, the Master Servicer
shall, no later than the Determination Date in the month of such final
distribution, notify the Trustee and the Trustee shall, no later than two (2)
Business Days after such Determination Date, mail on such date to each Holder of
such Class of Certificates a notice to the effect that: (i) the Trustee
anticipates that the final distribution with respect to such Class of

and surrender of such Certificates at the office of the Trustee or as otherwise
specified therein, and (ii) no interest shall accrue on such Certificates from

         Any funds not distributed to any Holder or Holders of Certificates of
such Class on such Distribution Date because of the failure of such Holder or
Holders to tender their Certificates shall, on such date, be set aside and held
in trust and credited to the account of the appropriate non-tendering Holder or
Holders. If any Certificates as to which notice has been given pursuant to this
Section 4.01(h) shall not have been surrendered for cancellation within six
months after the time specified in such notice, the Trustee shall mail a second
notice to the remaining non- tendering Certificateholders to surrender their
Certificates for cancellation in order to receive the final distribution with
respect thereto. If within six months after the second notice all such
Certificates shall not have been surrendered for cancellation, the Trustee shall
take reasonable steps as directed by the Company, or appoint an agent to take
reasonable steps, to contact the remaining non-tendering Certificateholders
concerning surrender of their Certificates. The costs and expenses of
maintaining the funds in trust and of contacting such Certificateholders shall
be paid out of the assets remaining in the Trust Fund. If within nine months
after the second notice any such Certificates shall not have been surrendered
for cancellation, the Class R Certificateholders shall be entitled to all
unclaimed funds and other assets which remain subject hereto. No interest shall
accrue or be payable to any Certificateholder on any amount held in trust as a
result of such Certificateholder's failure to surrender its Certificate(s) for
final payment thereof in accordance with this Section 4.01(h).

         (a) On the Business Day following each Determination Date, the Master
Servicer shall deliver to the Trustee a report, prepared as of the close of

         (b) The Master Servicer shall determine the aggregate amount of
Advances required to be made for the related Distribution Date, which shall be

of any related Debt Service Reductions or reductions in the amount of interest
collectable from the Mortgagor pursuant to the Relief Act, on the Outstanding

plus (2) with respect to each Balloon Loan delinquent in respect of its Balloon
Payment as of the close of business on the related Determination Date, an amount
equal to the assumed Monthly Payment (net of the related Servicing Fees) that
would have been

                                       98
<PAGE>

due on the related Due Date based on the original principal amortization
scheduled for such Balloon Loan until such Balloon Loan is finally liquidated;
provided that no Advance shall be made if it would be a Nonrecoverable Advance.
On or before 4:00 P.M. New York time on each Certificate Account Deposit Date,
the Master Servicer shall either (i) deposit in the Certificate Account from its
own funds, or funds received therefor from the Sub-Servicers, an amount equal to
the Advances to be made by the Master Servicer in respect of the related
Distribution Date, (ii) withdraw from amounts on deposit in the Custodial
Account and deposit in the Certificate Account all or a portion of the amounts
held for future distribution in discharge of any such Advance, or (iii) make
advances in the form of any combination of (i) and (ii) aggregating the amount
of such Advance. Any portion of the amounts held for future distribution so used
shall be replaced by the Master Servicer by deposit in the Certificate Account
on or before 1:00 P.M. New York time on any future Certificate Account Deposit
Date to the extent that funds attributable to the Mortgage Loans that are
available in the Custodial Account for deposit in the Certificate Account on
such Certificate Account Deposit Date shall be less than payments to
Certificateholders required to be made on the following Distribution Date. The
amount of any reimbursement pursuant to Section 3.11 in respect of outstanding
Advances on any Distribution Date shall be allocated to specific Monthly
Payments due but delinquent for previous Due Periods, which allocation shall be
made, to the extent practicable, to Monthly Payments which have been delinquent
for the longest period of time. Such allocations shall be conclusive for
purposes of reimbursement to the Master Servicer from recoveries on related
Mortgage Loans pursuant to Section 3.11. The determination by the Master
Servicer that it has made a Nonrecoverable Advance or that any proposed Advance,
if made, would constitute a Nonrecoverable Advance, shall be evidenced by a
certificate of a Servicing Officer delivered to the Seller and the Trustee with
the Remittance Report. The Trustee shall deposit all funds it receives pursuant
to this Section 4.03 into the Certificate Account.

         (c) In the event that the Master Servicer determines as of any
Certificate Account Deposit Date that it will be unable to deposit in the
Certificate Account an amount equal to the Advance required to be made for the
immediately succeeding Distribution Date in the amount determined by the Master
Servicer pursuant to paragraph (b) above, it shall give notice to the Trustee of
its inability to Advance (such notice may be given by telecopy), not later than
4:00 P.M., New York time, on such date, specifying the portion of such amount
that it will be unable to deposit. Not later than 4:00 P.M., New York time, on
the earlier of (x) two Business Days following such Certificate Account Deposit
Date or (y) the Business Day preceding the related Distribution Date, unless by
such time the Master Servicer shall have directly or indirectly deposited in the
Certificate Account the entire amount of the Advances required to be made for
the related Distribution Date, pursuant to Section 7.01, the Trustee shall (a)
terminate all of the rights and obligations of the Master Servicer under this
Agreement in accordance with Section 7.01 and (b) assume the rights and
obligations of the Master Servicer hereunder, including the obligation to
deposit in the Certificate Account an amount equal to the Advance for the

other than the Trustee or an Affiliate of the Trustee manages or advises such
investment, or on each Subsequent Transfer Date, if the Trustee or an Affiliate
of the Trustee manages or advises such investment or (iii) within one (1)

and pay such amount to or upon the order of the Company upon satisfaction of the
conditions set forth in Section 2.06 with respect to such transfer and
assignment;

                  (ii) If the amount on deposit in the Pre-Funding Account
(exclusive of

                                      100

the Interest Coverage Account shall be held in trust by the Trustee for the
Certificateholders for the uses and purposes set forth herein.

         (b) For federal income tax purposes, the Master Servicer shall be the
owner of the Interest Coverage Account and shall report all items of income,
deduction, gain or loss arising therefrom. At no time will the Interest Coverage
Account be an asset of any REMIC created hereunder. All income and gain realized
from investment of funds deposited in the Interest Coverage Account shall be for
the sole and exclusive benefit of the Master Servicer and shall be remitted by
the Trustee to the Master Servicer no later than the first Business Day
following receipt of such income and gain by the Trustee. The Master Servicer
shall deposit in the Interest Coverage Account the amount of any net loss
incurred in respect of any such Permitted Investment immediately upon
realization of such loss.

         (c) On each Distribution Date during the Funding Period and on the
Distribution Date immediately following the end of the Funding Period, the
Trustee shall withdraw from the Interest Coverage Account and deposit in the
Certificate Account an amount equal to 30 days' interest on the excess, if any,
of the Original Pre-Funded Amount over the aggregate Principal Balance of
Subsequent Mortgage Loans that both (i) had a Due Date during the Due Period
relating to such Distribution Date and (ii) had a Subsequent Cut-off Date prior
to the first day of

                                      101

the month in which such Distribution Date occurs, at a per annum rate equal to
the weighted average of the Net Mortgage Rates of the Mortgage Loans, plus the
Trustee's Fee Rate. Such withdrawal and deposit shall be treated as a
contribution of cash by the Master Servicer to REMIC 1 on the date thereof.
Immediately following any such withdrawal and deposit, and immediately following
the conveyance of any Subsequent Mortgage Loans to the Trust on any Subsequent
Transfer Date, the Trustee shall withdraw from the Interest Coverage Account and
remit to the Master Servicer or its designee an amount equal to the excess, if
any, of the amount remaining in such Interest Coverage Account over the amount
that would be required to be withdrawn therefrom (assuming sufficient funds
therein) pursuant to the preceding sentence on each subsequent Distribution
Date, if any, that will occur during the Funding Period or that will be the
Distribution Date immediately following the end of the Funding Period, if no
Subsequent Mortgage Loans were acquired by the Trust Fund after the end of the
Prepayment Period relating to the current Distribution Date.

         (d) Upon the earliest of (i) the Distribution Date immediately
following the end of the Funding Period, (ii) the reduction of the Certificate
Principal Balances of the Certificates to zero or (iii) the termination of this
Agreement in accordance with Section 9.01, any amount remaining on deposit in

         Section 4.08.     Information Reports to Be Filed by the Master
                           Servicer.

         The Master Servicer or the Sub-Servicers shall file information reports
with respect to the receipt of mortgage interest received in a trade or
business, foreclosures and abandonments of any Mortgaged Property and the
information returns relating to cancellation of indebtedness income with respect
to any Mortgaged Property required by Sections 6050H, 6050J and 6050P of the
Code, respectively, and deliver to the Trustee an Officers' Certificate stating
that such reports have been filed. Such reports shall be in form and substance
sufficient to meet the reporting requirements imposed by such Sections 6050H,
6050J and 6050P of the Code.

         Section 4.09.     Compliance with Withholding Requirements.

         Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal withholding requirements respecting payments to
Certificateholders of interest or original issue discount on the Mortgage Loans,
that the Trustee reasonably believes are applicable under the Code. The consent
of Certificateholders shall not be required for such withholding. In the event
the Trustee withholds any amount from interest or original issue discount
payments or advances thereof to any Certificateholder pursuant to federal
withholding requirements, the Trustee shall, together with its monthly report to
such Certificateholders pursuant to Section 4.02 hereof, indicate such amount
withheld.

         Section 4.10.     Distribution of Net WAC Shortfall REMIC Amount; Net
                           WAC Shortfall Reserve Fund.

         (a) On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of Class A Certificates (other than the Class
A-I-1 Certificates and Class A-IO Certificates), the Class M Certificates and
Class B Certificates, the Net WAC Shortfall Reserve Fund. In addition, on the
Closing Date, the Trustee shall deposit into the Net WAC Shortfall

                                      107
<PAGE>

Reserve Fund an amount equal to $210,000.

         (b) On each Distribution Date, to the extent required, the Trustee
shall make withdrawals from the Net WAC Shortfall Reserve Fund and use the
amounts in the Net WAC Shortfall Reserve Fund to make distributions to the Class
A Certificates (other than the Class A- I-1 Certificates and Class A-IO
Certificates), the Class M Certificates and Class B Certificates, in an amount
equal to the amount of any Net WAC Shortfall Amount on such Certificates. Any
such amounts shall be distributed first, to such Class A Certificates on a pro
rata basis, based on the related Net WAC Shortfall Amount thereon, and then to
the Class M-1, Class M-2 and Class B Certificates, in that order, in each case
until the related Net WAC Shortfall Amount has been reduced to zero. On the 30th
Distribution Date, after the distributions described in the preceding sentence,
the Trustee shall withdraw from the Net WAC Shortfall Reserve Fund (to the
extent of funds available on deposit therein) any remaining amounts and
distribute them to the Holders of the Class C Certificates.

         (c) The Net WAC Shortfall Reserve Fund shall be an Eligible Account.
Amounts held in the Net WAC Shortfall Reserve Fund from time to time shall
continue to constitute assets of the Trust Fund, but not of the REMICs, until
released from the Net WAC Shortfall Reserve Fund pursuant to this Section 4.10.
The Net WAC Shortfall Reserve Fund constitutes an "outside reserve fund" within
the meaning of Treasury Regulation ss.ss. 1.860G-2(h) and is not an asset of the
REMICs. The Holders of the Class C Certificates shall be the owner of the Net
WAC Shortfall Reserve Fund. The Trustee shall keep records that accurately
reflect the funds on deposit in the Net WAC Shortfall Reserve Fund. The Trustee
shall, at the direction of the Majority Class C Certificateholder, invest
amounts on deposit in the Net WAC Shortfall Reserve Fund in Permitted
Investments. In the absence of written direction to the Trustee from the
Majority Class C Certificateholder, all funds in the Net WAC Shortfall Reserve
Fund shall remain uninvested. On each Distribution Date, the Trustee shall
distribute any interest earned on the Net WAC Shortfall Reserve Fund to the
Holders of the Class C Certificates.

         (d) For federal income tax purposes, the Trustee intends to take the
position that the right to receive the Net WAC Shortfall Amount has a value of
0.54% of the initial Certificate Principal Balance of each of the Class A-I-6
Certificates, the Class M-1 Certificates, the Class M-2 Certificates and Class B
Certificates, and a DE MINIMUS value with respect to the other Certificates
entitled to receive the Net WAC Shortfall Amount.

                                THE CERTIFICATES

         Section 5.01.     The Certificates.

         (a) The Certificates will be substantially in the respective forms
annexed hereto as Exhibits A and B-1 through B-4. The Certificates will be
issuable in registered form only. The Certificates (other than the Class P
Certificates, the Class C Certificates and the Class R Certificates) will be
issued in minimum denominations of $25,000 Initial Certificate Principal Balance
or Initial Notional Amount, as applicable, and integral multiples of $1 in
excess thereof. The Class C Certificates will be issued in minimum denominations
of $1.00 Initial Notional Amount and integral multiples of $1.00 in excess
thereof. The Class P Certificates and the Class R Certificates will each be
issuable in minimum denominations of any Percentage Interest representing 20.00%
and multiples of 0.01% in excess thereof.

         Upon original issue, the Certificates shall, upon the written request
of the Company executed by an officer of the Company, be executed and delivered
by the Trustee, authenticated by the Trustee and delivered to or upon the order
of the Company upon receipt by the Trustee of the documents specified in Section
2.01. The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee in its capacity as trustee hereunder by a Responsible
Officer. Certificates bearing the manual or facsimile signatures of individuals
who were at the time they signed the proper officers of the Trustee shall bind
the Trustee, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Certificates
or did not hold such offices at the date of such Certificates. No Certificate
shall be entitled to any benefit under this Agreement, or be valid for any
purpose, unless there appears on such Certificate a certificate of
authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Certificate shall be
conclusive evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates issued on the Closing
Date shall be dated the Closing Date and any Certificates delivered thereafter
shall be dated the date of their authentication.

         (b) The Class A Certificates and the Mezzanine Certificates shall
initially be issued as one or more Certificates registered in the name of the
Depository or its nominee and, except as provided below, registration of such
Certificates may not be transferred by the Trustee except to another Depository
that agrees to hold such Certificates for the respective Certificate Owners with
Ownership Interests therein. The Certificate Owners shall hold their respective
Ownership Interests in and to each of such Book-Entry Certificates through the
book-entry facilities of the Depository and, except as provided below, shall not
be entitled to Definitive Certificates in respect of such Ownership Interests.
All transfers by Certificate Owners of their respective Ownership Interests in
the Book-Entry Certificates shall be made in accordance with the

                                      109
<PAGE>

procedures established by the Depository Participant or brokerage firm
representing such Certificate Owner. Each Depository Participant shall transfer
the Ownership Interests only in the Book-Entry Certificates of Certificate
Owners it represents or of brokerage firms for which it acts as agent in
accordance with the Depository's normal procedures. The Trustee shall not be
required to monitor, determine or inquire as to compliance with the transfer
restrictions with respect to the Book-Entry Certificates, and the Trustee shall
have no liability for transfers of Ownership Interests in the Book Entry
Certificates made through the book-entry facilities of the Depositary or between
or among Depositary Participants or Certificate Owners, made in violation of the
applicable restrictions.

         The Trustee, the Master Servicer and the Company may for all purposes
(including the making of payments due on the respective Classes of Book-Entry
Certificates) deal with the Depository as the authorized representative of the
Certificate Owners with respect to the respective Classes of Book-Entry
Certificates for the purposes of exercising the rights of Certificateholders
hereunder. The rights of Certificate Owners with respect to the respective
Classes of Book-Entry Certificates shall be limited to those established by law
and agreements between such Certificate Owners and the Depository Participants
and brokerage firms representing such Certificate Owners. Multiple requests and
directions from, and votes of, the Depository as Holder of any Class of
Book-Entry Certificates with respect to any particular matter shall not be
deemed inconsistent if they are made with respect to different Certificate
Owners. The Trustee may establish a reasonable record date in connection with
solicitations of consents from or voting by Certificateholders and shall give
notice to the Depository of such record date.

         If (i)(A) the Company advises the Trustee in writing that the
Depository is no longer willing or able to properly discharge its
responsibilities as Depository and (B) the Company is unable to locate a
qualified successor or (ii) the Company at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the
Depository, the Trustee shall notify all Certificate Owners, through the
Depository, of the occurrence of any such event and of the availability of
Definitive Certificates to Certificate Owners requesting the same. Upon
surrender to the Trustee of the Book-Entry Certificates by the Depository,
accompanied by registration instructions from the Depository for registration of
transfer, the Trustee shall, at the expense of the Company, issue the Definitive
Certificates. Neither the Company, the Master Servicer nor the Trustee shall be
liable for any actions taken by the Depository or its nominee, including,
without limitation, 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 Certificates the Trustee and the Master Servicer
shall recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

         (c) Each Certificate is intended to be a "security" governed by Article
8 of the Uniform Commercial Code as in effect in the State of New York and any
other applicable jurisdiction, to the extent that any of such laws may be
applicable.

         Section 5.02.     Registration of Transfer and Exchange of
                           Certificates.

         (a) The Trustee shall maintain a Certificate Register in which, subject
to such reasonable regulations as it may prescribe, the Trustee shall provide
for the registration of Certificates and of transfers and exchanges of
Certificates as herein provided.

         (b) Except as provided in Section 5.02(c), no transfer, sale, pledge or
other disposition of a Class P Certificate, Class C Certificate or a Class R
Certificate shall be made unless such transfer, sale, pledge or other
disposition is exempt from the registration requirements of the Securities Act
of 1933, as amended (the "Act"), and any applicable state securities laws or is
made in accordance with said Act and laws. In the event that a transfer of a
Class P Certificate, Class C Certificate or Class R Certificate is to be made
under this Section 5.02(b), (i) the Trustee shall require an Opinion of Counsel
acceptable to and in form and substance satisfactory to the Trustee that such
transfer shall be made pursuant to an exemption, describing the applicable
exemption and the basis therefor, from said Act and laws or is being made
pursuant to said Act and laws, which Opinion of Counsel shall not be an expense
of the Trustee, the Company or the Master Servicer, provided that such Opinion
of Counsel will not be required in connection with the initial transfer of any
such Certificate by the Company or any affiliate thereof, to a non-affiliate of
the Company and (ii) the Trustee shall require the transferee to execute a
representation letter, substantially in the form of Exhibit G-1 hereto, and the
Trustee shall require the transferor to execute a representation letter,
substantially in the form of Exhibit G-2 hereto, each acceptable to and in form
and substance satisfactory to the Trustee certifying to the Company and the
Trustee the facts surrounding such transfer, which representation letters shall
not be an expense of the Trustee, the Company or the Master Servicer; provided,
however, that such representation letters will not be required in connection
with any transfer of any such Certificate by the Company to an affiliate of the
Company and the Trustee shall be entitled to conclusively rely upon a
representation (which, upon the request of the Trustee, shall be a written
representation) from the Company of the status of such transferee as an
affiliate of the Company. Any such Certificateholder desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee, the Company and
the Master Servicer against any liability that may result if the transfer is not
so exempt or is not made in accordance with such applicable federal and state
laws.

         (c) Notwithstanding the requirements of Section 5.02(b), transfers of
Class P Certificates, Class C Certificates and Class R Certificates may be made
in accordance with this Section 5.02(c) if the prospective transferee of a
Certificate provides the Trustee and the Company with an investment letter
substantially in the form of Exhibit G-3 attached hereto, which investment
letter shall not be an expense of the Trustee, the Company or the Master
Servicer, and which investment letter states that, among other things, such
transferee is a "qualified institutional buyer" as defined under Rule 144A. Such
transfers shall be deemed to have complied with the requirements of Section
5.02(b) hereof; provided, however, that no

                                      111
<PAGE>

Transfer of any of the Class P Certificates, Class C Certificates or Class R
Certificates may be made pursuant to this Section 5.02(c) by the Company. Any
such Certificateholder desiring to effect such transfer shall, and does hereby
agree to, indemnify the Trustee, the Company and the Master Servicer against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such applicable federal and state laws.

         The Trustee shall require an Opinion of Counsel from a prospective
transferee prior to the transfer of any Class P Certificate, Class C Certificate
or Class R Certificate to any employee benefit plan or other retirement
arrangement, including individual retirement accounts and Keogh plans, that is
subject to Section 406 of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA") or Section 4975 of the Code (any of the foregoing, a
"Plan"), to a trustee or other Person acting on behalf of any Plan, or to any
other person who is using "plan assets" of any Plan to effect such acquisition
(including any insurance company using funds in its general or separate accounts
that may constitute "plan assets"). Such Opinion of Counsel must establish to
the satisfaction of the Trustee that such transfer is permissible under
applicable law, will not violate the prohibited transaction provisions of
Section 406 of ERISA and Section 4975 of the Code, will not cause the assets of
the Trust Fund to constitute "plan assets" within the meaning of 29 C.F.R. ss.
2510.3-101, and will not subject the Trustee, the Master Servicer or the Company
to any obligation in addition to those undertaken in this Agreement. Neither the
Company, the Master Servicer nor the Trustee will be required to obtain such
Opinion of Counsel on behalf of any prospective transferee.

         (d)      [Reserved]

         (e) (i) Each Person who has or who acquires any Ownership Interest in a
Class R Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions and to
have irrevocably authorized the Trustee or its designee under clause (iii)(A)
below to deliver payments to a Person other than such Person and to negotiate
the terms of any mandatory sale under clause (iii)(B) below and to execute all
instruments of transfer and to do all other things necessary in connection with
any such sale. The rights of each Person acquiring any Ownership Interest in a
Class R Certificate are expressly subject to the following provisions:

                  (A) Each Person holding or acquiring any Ownership Interest in
a Class R Certificate shall be a Permitted Transferee and shall promptly notify
the Trustee of any change or impending change in its status as a Permitted
Transferee.

                  (B) In connection with any proposed Transfer of any Ownership
Interest in a Class R Certificate, the Trustee shall require delivery to it, and
shall not register the Transfer of any Class R Certificate until its receipt of
(I) an affidavit and agreement (a "Transfer Affidavit and Agreement" in the form
attached hereto as Exhibit G-5) from the proposed Transferee, in form and
substance satisfactory to the Trustee representing and warranting, among other
things,

                                      112
<PAGE>
<PAGE>

that it is a Permitted Transferee, that it is not acquiring its Ownership
Interest in the Class R Certificate that is the subject of the proposed Transfer
as a nominee, trustee or agent for any Person who is not a Permitted Transferee,
that for so long as it retains its Ownership Interest in a Class R Certificate,
it will endeavor to remain a Permitted Transferee, and that it has reviewed the
provisions of this Section 5.02 and agrees to be bound by them, and (II) a
certificate, in the form attached hereto as Exhibit G-4, from the Holder wishing
to transfer the Class R Certificate, in form and substance satisfactory to the
Trustee representing and warranting, among other things, that no purpose of the
proposed Transfer is to impede the assessment or collection of tax.

                  (C) Notwithstanding the delivery of a Transfer Affidavit and
Agreement by a proposed Transferee under clause (B) above, if a Responsible
Officer of the Trustee assigned to this transaction has actual knowledge that
the proposed Transferee is not a Permitted Transferee, no Transfer of an
Ownership Interest in a Class R Certificate to such proposed Transferee shall be
effected.

                  (D) Each Person holding or acquiring any Ownership Interest in
a Class R Certificate shall agree (x) to require a Transfer Affidavit and
Agreement from any other Person to whom such Person attempts to transfer its
Ownership Interest in a Class R Certificate and (y) not to transfer its
Ownership Interest unless it provides a certificate to the Trustee in the form
attached hereto as Exhibit G-4.

                  (E) Each Person holding or acquiring an Ownership Interest in
a Class R Certificate, by purchasing an Ownership Interest in such Certificate,
agrees to give the Trustee written notice that it is a "pass-through interest
holder" within the meaning of Temporary Treasury Regulations Section
1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership Interest in a Class
R Certificate, if it is "a pass-through interest holder", or is holding an
Ownership Interest in a Class R Certificate on behalf of a "pass-through
interest holder."

         (ii) The Trustee will register the Transfer of any Class R Certificate
only if it shall have received the Transfer Affidavit and Agreement in the form
attached hereto as Exhibit G-5, a certificate of the Holder requesting such
transfer in the form attached hereto as Exhibit G-4 and all of such other
documents as shall have been reasonably required by the Trustee as a condition
to such registration. Transfers of the Class R Certificates other than to
Permitted Transferees are prohibited.

         (iii) (A) If any Person other than a Permitted Transferee shall become
a Holder of a Class R Certificate, then the last preceding Permitted Transferee
shall be restored, to the extent permitted by law, to all rights and obligations
as Holder thereof retroactive to the date of registration of such Transfer of
such Class R Certificate. If a Non-United States Person shall become a Holder of
a Class R Certificate, then the last preceding Permitted Transferee shall be
restored, to the extent permitted by law, to all rights and obligations as
Holder thereof retroactive to the date of registration of such Transfer of such
Class R Certificate. If a transfer of a Class R

                                      113
<PAGE>

Certificate is disregarded pursuant to the provisions of Treasury Regulations
Section 1.860E-1 or Section 1.860G-3, then the last preceding Permitted
Transferee shall be restored, to the extent permitted by law, to all rights and
obligations as Holder thereof retroactive to the date of registration of such
transfer of such Class R Certificate. The prior Holder shall be entitled to
recover from any purported Holder of a Class R Certificate that was in fact not
a Permitted Transferee under this Section 5.05(b) at the time it became a Holder
all payments made on such Class R Certificate. Each Holder of a Class R
Certificate, by acceptance thereof, shall be deemed for all purposes to have
consented to the provisions of this clause (b) and to any amendment of this
Agreement deemed necessary (whether as a result of new legislation or otherwise)
by counsel of the Company to ensure that the Class R Certificates are not
transferred to any Person who is not a Permitted Transferee and that any
transfer of such Class R Certificates will not cause the imposition of a tax
upon the Trust or cause any such REMIC to fail to qualify as a REMIC. The
Trustee shall be under no liability to any Person for any registration of
Transfer of a Class R Certificate that is in fact not permitted by this Section
5.02 or for making any payments due on such Certificate to the holder thereof or
for taking any other action with respect to such holder under the provisions of
this Agreement.

                  (B) If any purported Transferee shall become a Holder of a
Class R Certificate in violation of the restrictions in this Section 5.02 and to
the extent that the retroactive restoration of the rights of the Holder of such
Class R Certificate as described in clause (iii)(A) above shall be invalid,
illegal or unenforceable, then the Trustee shall have the right, without notice
to the holder or any prior holder of such Class R Certificate, to sell such
Class R Certificate to a purchaser selected by the Trustee on such terms as the
Trustee may choose. Such purported Transferee shall promptly endorse and deliver
each Class R Certificate in accordance with the instructions of the Trustee.
Such purchaser may be the Trustee itself. The proceeds of such sale, net of the
commissions (which may include commissions payable to the Trustee), expenses and
taxes due, if any, will be remitted by the Trustee to such purported Transferee.
The terms and conditions of any sale under this clause (iii)(B) shall be
determined in the sole discretion of the Trustee, and the Trustee shall not be
liable to any Person having an Ownership Interest in a Class R Certificate as a
result of its exercise of such discretion.

         (iv) The Trustee shall make available to the Internal Revenue Service
and those Persons specified by the REMIC Provisions, all information necessary
to compute any tax imposed (A) as a result of the transfer of an ownership
interest in a Class R Certificate to any Person who is a Disqualified
Organization, including the information regarding "excess inclusions" of such
Class R Certificates required to be provided to the Internal Revenue Service and
certain Persons as described in Treasury Regulations Sections 1.860D-1(b)(5) and
1.860E- 2(a)(5), and (B) as a result of any regulated investment company, real
estate investment trust, common trust fund, partnership, trust, estate or
organization described in Section 1381 of the Code that holds an Ownership
Interest in a Class R Certificate having as among its record holders at any time
any Person who is a Disqualified Organization. The Trustee may charge and shall
be entitled to reasonable compensation for providing such information as may be
required

                                      114
<PAGE>

from those Persons which may have had a tax imposed upon them as specified in
clauses (A) and (B) of this paragraph for providing such information.

                  (F) Subject to the preceding paragraphs, upon surrender for
registration of transfer of any Certificate at the office of the Trustee
maintained for such purpose, the Trustee shall execute and the Trustee shall
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of the same Class of a like aggregate
Percentage Interest. Every Certificate surrendered for transfer shall be
accompanied by notification of the account of the designated transferee or
transferees for the purpose of receiving distributions pursuant to Section 4.01
by wire transfer, if any such transferee desires and is eligible for
distribution by wire transfer.

                  (G) At the option of the Certificateholders, Certificates may
be exchanged for other Certificates of authorized denominations of the same
Class of a like aggregate Percentage Interest, upon surrender of the
Certificates to be exchanged at the office of the Trustee. Whenever any
Certificates are so surrendered for exchange the Trustee shall execute,
authenticate and deliver the Certificates which the Certificateholder making the
exchange is entitled to receive. Every Certificate presented or surrendered for
transfer or exchange shall (if so required by the Trustee) be duly endorsed by,
or be accompanied by a written instrument of transfer in the form satisfactory
to the Trustee duly executed by, the Holder thereof or his attorney duly
authorized in writing. In addition, with respect to each Class R Certificate,
the Holder thereof may exchange, in the manner described above, such Class R
Certificate for three separate Certificates, each representing such Holder's
respective Percentage Interest in the Class R-1 Interest, the Class R-2 Interest
and the Class R-3 Interest, respectively, in each case that was evidenced by the
Class R Certificate being exchanged.

                  (H) No service charge shall be made to the Certificateholders
for any transfer or exchange of Certificates, but the Trustee may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer or exchange of Certificates.

                  (I) All Certificates surrendered for transfer and exchange
shall be canceled and retained by the Trustee in accordance with the Trustee's
standard procedures.

         Section 5.03.     Mutilated, Destroyed, Lost or Stolen Certificates.

         If (i) any mutilated Certificate is surrendered to the Trustee and the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate, and (ii) there is delivered to the Trustee such security or
indemnity as may be required by it to save it harmless, then, in the absence of
notice to the Trustee that such Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute, authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of the same Class and

                                      115
<PAGE>

Percentage Interest. Upon the issuance of any new Certificate under this
Section, the Trustee may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee) connected
therewith. Any replacement Certificate issued pursuant to this Section shall
constitute complete and indefeasible evidence of ownership in the Trust Fund, as
if originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

         Section 5.04.     Persons Deemed Owners.

         The Company, the Master Servicer, the Trustee and any agent of any of
them may treat the person in whose name any Certificate is registered as the
owner of such Certificate for the purpose of receiving distributions pursuant to
Section 4.01 and for all other purposes whatsoever, and neither the Company, the
Master Servicer, the Trustee nor any agent of any of them shall be affected by
notice to the contrary.

         Section 5.05.     Rule 144A Information.

         For so long as any Class P Certificates, Class C Certificates and Class
R Certificates are outstanding and are "restricted securities" within the
meaning of Rule 144(a)(3) of the Securities Act, (1) the Company will provide or
cause to be provided to any holder of such Certificates and any prospective
purchaser thereof designated by such a holder, upon the request of such holder
or prospective purchaser, the information required to be provided to such holder
or prospective purchaser by Rule 144A(d)(4) under the Securities Act; and (2)
the Company shall update such information from time to time in order to prevent
such information from becoming false and misleading and will take such other
actions as are necessary to ensure that the safe harbor exemption from the
registration requirements of the Securities Act under Rule 144A is and will be
available for resales of such Certificates conducted in accordance with Rule
144A. The Master Servicer shall cooperate with the Company and furnish the
Company such information in the Master Servicer's possession as the Company may
reasonably request.

                                   ARTICLE VI

                       THE COMPANY AND THE MASTER SERVICER

         Section 6.01.     Liability of the Company and the Master Servicer.

         The Company and the Master Servicer each shall be liable in accordance
herewith only to the extent of the obligations specifically imposed upon and
undertaken by the Company and the Master Servicer herein. Only the Master
Servicer, any successor Master Servicer or the Trustee acting as Master Servicer
shall be liable with respect to the servicing of the Mortgage Loans and the REO
Property for actions taken by any such Person in contravention of the Master
Servicer's duties hereunder.

         Section 6.02.     Merger, Consolidation or Conversion of the Company or
                           the Master Servicer.

         The Company and the Master Servicer each will keep in full effect its
existence, rights and franchises as a corporation under the laws of the state of
its incorporation, and each will obtain and preserve its qualification to do
business as a foreign corporation in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

         Any Person into which the Company or the Master Servicer may be merged,
consolidated or converted, or any corporation resulting from any merger or
consolidation to which the Company or the Master Servicer shall be a party, or
any Person succeeding to the business of the Company or the Master Servicer,
shall be the successor of the Company or the Master Servicer, as the case may
be, hereunder, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, however, that the successor or surviving Person to
the Master Servicer shall be qualified to sell mortgage loans to and service
mortgage loans for Fannie Mae or Freddie Mac.

         Section 6.03.     Limitation on Liability of the Company, the Master
                           Servicer and Others.

         Neither the Company, the Master Servicer nor any of the directors,
officers, employees or agents of the Company or the Master Servicer shall be
under any liability to the Trust Fund or the Certificateholders for any action
taken or for refraining from the taking of any action in good faith pursuant to
this Agreement, or for errors in judgment; provided, however, that this
provision shall not protect the Company or the Master Servicer (but this
provision shall protect the above described persons) against any breach of
warranties or representations made herein, or against any specific liability
imposed on the Master Servicer pursuant to Section 3.01 or any other Section
hereof; and provided further that this provision shall not protect the Company,
the

                                      117
<PAGE>

Master Servicer or any such person, against any liability which would otherwise
be imposed by reason of willful misfeasance, bad faith or gross negligence in
the performance of duties or by reason of reckless disregard of obligations and
duties hereunder. The Company, the Master Servicer and any director, officer,
employee or agent of the Company or the Master Servicer may rely in good faith
on any document of any kind PRIMA FACIE properly executed and submitted by any
Person respecting any matters arising hereunder. The Company, the Master
Servicer and any director, officer, employee or agent of the Company or the
Master Servicer shall be indemnified and held harmless by the Trust Fund against
any loss, liability or expense incurred in connection with any legal action
relating to this Agreement or the Certificates (including reasonable legal fees
and disbursements of counsel), other than (a) any loss, liability or expense
related to Master Servicer's servicing obligations with respect to any specific
Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense
shall be otherwise reimbursable pursuant to this Agreement) or related to the
Master Servicer's obligations under Section 3.01, or (b) any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or gross negligence
in the performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. Neither the Company nor the Master Servicer
shall be under any obligation to appear in, prosecute or defend any legal action
which is not incidental to its respective duties under this Agreement and which
in its opinion may involve it in any expense or liability; provided, however,
that the Company or the Master Servicer may in its sole discretion undertake any
such action which it may deem necessary or desirable with respect to this
Agreement and the rights and duties of the parties hereto and the interests of
the Certificateholders hereunder. In such event, the legal expenses and costs of
such action and any liability resulting therefrom (except any action or
liability related to the Master Servicer's obligations under Section 3.01) shall
be expenses, costs and liabilities of the Trust Fund, and the Company and the
Master Servicer shall be entitled to be reimbursed therefor from the Certificate
Account as provided in Section 3.11, any such right of reimbursement being prior
to the rights of Certificateholders to receive any amount in the Certificate
Account.

         Section 6.04.     Limitation on Resignation of the Master Servicer.

         The Master Servicer shall not resign from the obligations and duties
hereby imposed on it except (a) upon appointment of a successor servicer
reasonably acceptable to the Trustee upon receipt by the Trustee of a letter
from each Rating Agency (obtained by the Master Servicer and at its expense)
that such a resignation and appointment will not, in and of itself, result in a
downgrading of the Certificates or (b) upon determination that its duties
hereunder are no longer permissible under applicable law. Any such determination
permitting the resignation of the Master Servicer shall be evidenced by an
Opinion of Counsel (at the expense of the resigning Master Servicer) to such
effect delivered to the Trustee. No such resignation shall become effective
until the Trustee or a successor servicer shall have assumed the Master
Servicer's responsibilities, duties, liabilities and obligations hereunder.

                                      118
<PAGE>

         Section 6.05.     Sale and Assignment of Master Servicing.

         The Master Servicer may sell and assign its rights and delegate its
duties and obligations in their entirety as Master Servicer under this
Agreement; provided, however, that: (i) the purchaser or transferee accepting
such assignment and delegation (a) shall be a Person which shall be qualified to
service mortgage loans for Fannie Mae or Freddie Mac; (b) shall, in the case of
successor master servicers only, have a net worth of not less than $10,000,000
(unless otherwise approved by each Rating Agency pursuant to clause (ii) below);
(c) shall be reasonably satisfactory to the Trustee (as evidenced in a writing
signed by the Trustee) as having a comparable servicing ability to that of the
Master Servicer on the Closing Date; (d) shall execute and deliver to the
Trustee an agreement, in form and substance reasonably satisfactory to the
Trustee, which contains an assumption by such Person of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by it as master servicer under this Agreement and any custodial
agreement, from and after the effective date of such agreement; (ii) each Rating
Agency shall be given prior written notice of the identity of the proposed
successor to the Master Servicer and each Rating Agency's rating of the
Certificates in effect immediately prior to such assignment, sale and delegation
will not be downgraded or withdrawn as a result of such assignment, sale and
delegation, as evidenced by a letter to such effect obtained by the Master
Servicer at its expense and delivered to the Trustee; and (iii) the Master
Servicer assigning and selling the master servicing shall deliver to the Trustee
an Officer's Certificate and an Opinion of Counsel (at the expense of the Master
Servicer), each stating that all conditions precedent to such action under this
Agreement have been completed and such action is permitted by and complies with
the terms of this Agreement. No such assignment or delegation shall affect any
liability of the Master Servicer arising prior to the effective date thereof.

                                     DEFAULT

         Section 7.01.     Events of Default.

         "Event of Default", wherever used herein, means any one of the
following events:

         (i) any failure by the Master Servicer to deposit into the Certificate
Account on each Certificate Account Deposit Date the amounts required to be
deposited therein (other than an Advance) under the terms of this Agreement
which continues unremedied for two (2) Business Days after such amount was
required to be remitted; or

         (ii) any failure on the part of the Master Servicer duly to observe or
perform in any material respect any other of the covenants or agreements on the
part of the Master Servicer contained in the Certificates or in this Agreement
(including any breach of the Master Servicer's representations and warranties
pursuant to Section 2.03(a) which materially and adversely affects the interests
of the Certificateholders) which continues unremedied for a period of 60 days
after the date on which written notice of such failure, requiring the same to be
remedied, shall have been given to the Master Servicer by the Trustee, or to the
Master Servicer and the Trustee by the Holders of Certificates entitled to at
least 25% of the Voting Rights; or

         (iii) a decree or order of a court or agency or supervisory authority
having jurisdiction in an involuntary case under any present or future federal
or state bankruptcy, insolvency or similar law or the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshaling of assets and liabilities or similar proceedings, or for the
winding-up or liquidation of its affairs, shall have been entered against the
Master Servicer and such decree or order shall have remained in force
undischarged or unstayed for a period of 60 consecutive days; or

         (iv) the Master Servicer shall consent to the appointment of a
conservator or receiver or liquidator in any insolvency, readjustment of debt,
marshaling of assets and liabilities or similar proceedings of or relating to
the Master Servicer or of or relating to all or substantially all of its
property; or

         (v) the Master Servicer shall admit in writing its inability to pay its
debts generally as they become due, file a petition to take advantage of or
otherwise voluntarily commence a case or proceeding under any applicable
bankruptcy, insolvency, reorganization or other similar statute, make an
assignment for the benefit of its creditors, or voluntarily suspend payment of
its obligations; or

         (vi) the Master Servicer shall fail to deposit in the Certificate
Account on any

                                      120
<PAGE>

Certificate Account Deposit Date an amount equal to any required Advance which
continues unremedied for the earlier of (a) a period of two (2) Business Days or
(b) the Business Day immediately preceding the Distribution Date.

         If an Event of Default described in clauses (i) - (v) of this Section
shall occur, then, and in each and every such case, so long as such Event of
Default shall not have been remedied, the Trustee or the Holders of Certificates
entitled to at least 51% of the Voting Rights, by notice in writing to the
Master Servicer (and to the Trustee if given by such Holders of Certificates),
with a copy to the Rating Agencies, may terminate all of the rights and
obligations (but not the liabilities) of the Master Servicer under this
Agreement and in and to the Trust Fund, other than its rights as a
Certificateholder hereunder; provided, however, that the successor to the Master
Servicer appointed pursuant to Section 7.02 shall have accepted the duties of
Master Servicer effective upon the resignation or termination of the Master
Servicer. If an Event of Default described in clause (vi) hereof shall occur,
the Trustee shall, by notice to the Master Servicer, and the Company, terminate
all of the rights and obligations of the Master Servicer under this Agreement
and in and to the Trust Fund, other than its rights as a Certificateholder
hereunder; provided, however, that if the Trustee determines (in its sole
discretion) that the failure by the Master Servicer to make any required Advance
was due to circumstances beyond its control, and the required Advance was
otherwise made, the Trustee shall not terminate the Master Servicer. On or after
the receipt by the Master Servicer of such notice, all authority and power of
the Master Servicer under this Agreement, whether with respect to the
Certificates (other than as a holder thereof) or the Mortgage Loans or
otherwise, shall pass to and be vested in the Trustee pursuant to and under this
Section, and, without limitation, the Trustee is hereby authorized and empowered
to execute and deliver, on behalf of the Master Servicer, as attorney-in-fact or
otherwise, any and all documents and other instruments, and to do or accomplish
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, whether to complete the transfer and endorsement or
assignment of the Mortgage Loans and related documents, or otherwise at the
expense of the Master Servicer. The Master Servicer agrees to cooperate with
(and pay any related costs and expenses of) the Trustee in effecting the
termination of the Master Servicer's responsibilities and rights hereunder,
including, without limitation, the transfer to the Trustee or the successor
Master Servicer for administration by it of (i) the property and amounts which
are then or should be part of the Trust Fund or which thereafter become part of
the Trust Fund; (ii) originals or copies of all documents of the Master Servicer
reasonably requested by the Trustee to enable it to assume the Master Servicer's
duties thereunder; (iii) the rights and obligations of the Master Servicer under
the Sub-Servicing Agreements with respect to the Mortgage Loans; and (iv) all
cash amounts which shall at the time be deposited by the Master Servicer or
should have been deposited to the Custodial or the Certificate Account or
thereafter be received with respect to the Mortgage Loans. The Trustee shall not
be deemed to have breached any obligation hereunder as a result of a failure to
make or delay in making any distribution as and when required hereunder caused
by the failure of the Master Servicer to remit any amounts received by it or to
deliver any documents held by it with respect to the Mortgage Loans. For
purposes of this Section 7.01, the Trustee shall not be

                                      121
<PAGE>

deemed to have knowledge of an Event of Default unless a Responsible Officer of
the Trustee has actual knowledge thereof or unless notice of any event which is
in fact such an Event of Default is received by the Trustee as provided in
Section 11.05 and such notice references the Certificates, the Trust Fund or
this Agreement.

         Section 7.02.     Trustee to Act; Appointment of Successor.

         Within 90 days of the time the Master Servicer receives a notice of
termination pursuant to Section 7.01(i) - (v), the Trustee or its appointed
agent shall be the successor in all respects to the Master Servicer in its
capacity as Master Servicer under this Agreement and the transactions set forth
or provided for herein and shall be subject thereafter to all the
responsibilities, duties and liabilities relating thereto placed on the Master
Servicer including the obligation to make Advances which have been or will be
required to be made (except for the responsibilities, duties and liabilities
contained in Section 2.03 and its obligations to deposit amounts in respect of
losses pursuant to Section 3.12 and 4.01(h)) by the terms and provisions hereof;
and provided further, that any failure to perform such duties or
responsibilities caused by the Master Servicer's failure to provide information
required by Section 4.03 shall not be considered a default by the Trustee
hereunder. As compensation therefor, the Trustee shall be entitled to all funds
relating to the Mortgage Loans which the Master Servicer would have been
entitled to charge to the Custodial Account and the Certificate Account if the
Master Servicer had continued to act hereunder. If the Trustee has become the
successor to the Master Servicer in accordance with Section 6.04 or Section
7.02, then notwithstanding the above, if the Trustee shall be unwilling to so
act, or shall be unable to so act, the Trustee may appoint, or petition a court
of competent jurisdiction or appoint, any established housing and home finance
institution, which is also a Fannie Mae- or Freddie Mac-approved mortgage
servicing institution, having a net worth of not less than $10,000,000 as the
successor to the Master Servicer hereunder in the assumption of all or any part
of the responsibilities, duties or liabilities of the Master Servicer hereunder.
Pending appointment of a successor to the Master Servicer hereunder, the Trustee
shall act in such capacity as herein above provided. In connection with such
appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; provided, however, that no such compensation shall be in
excess of that permitted the Master Servicer hereunder. Each of the Seller, the
Trustee and such successor shall take such action, consistent with this
Agreement, as shall be necessary to effectuate any such succession. In no event
shall the successor Master Servicer be liable for the acts or omissions of the
predecessor Master Servicer.

         In connection with the termination or resignation of the Master
Servicer hereunder, either (i) the successor Master Servicer, including the
Trustee if the Trustee is acting as successor Master Servicer, shall represent
and warrant that it is a member of MERS in good standing and shall agree to
comply in all material respects with the rules and procedures of MERS in
connection with the servicing of the Mortgage Loans that are registered with
MERS, in which case the predecessor Master Servicer shall cooperate with the
successor Master Servicer in

                                      122
<PAGE>

causing MERS to revise its records to reflect the transfer of servicing to the
successor Master Servicer as necessary under MERS' rules and regulations, or
(ii) the predecessor Master Servicer shall cooperate with the successor Master
Servicer in causing MERS to execute and deliver an assignment of Mortgage in
recordable form to transfer the Mortgage from MERS to the Trustee and to execute
and deliver such other notices, documents and other instruments as may be
necessary or desirable to effect a transfer of such Mortgage Loan or servicing
of such Mortgage Loan on the MERS(R) System to the successor Master Servicer.
The predecessor Master Servicer shall file or cause to be filed any such
assignment in the appropriate recording office. The predecessor Master Servicer
shall bear any and all fees of MERS, costs of preparing any assignments of
Mortgage, and fees and costs of filing any assignments of Mortgage that may be
required under this Section 7.02. The successor Master Servicer shall cause such
assignment to be delivered to the Trustee promptly upon receipt of the original
with evidence of recording thereon or a copy certified by the public recording
office in which such assignment was recorded.

         Any successor, including the Trustee, to the Master Servicer shall
maintain in force during its term as master servicer hereunder policies and
fidelity bonds to the same extent as the Master Servicer is so required pursuant
to Section 3.18.

         Notwithstanding anything else herein to the contrary, in no event shall
the Trustee be liable for any Servicing Fee or for any differential in the
amount of the Servicing Fee paid hereunder and the amount necessary to induce
any successor Master Servicer or Servicer, as applicable, to act as successor
Master Servicer or Servicer, as applicable, under this Agreement and the
transactions set forth or provided for herein.

         Section 7.03.     Notification to Certificateholders.

         (a) Upon any such termination or appointment of a successor to the
Master Servicer, the Trustee shall give prompt notice thereof to
Certificateholders and to the Rating Agencies.

         (b) Within 60 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Holders of Certificates notice of each
such Event of Default hereunder known to the Trustee, unless such Event of
Default shall have been cured or waived.

         Section 7.04.     Waiver of Events of Default.

         The Holders representing at least 51% of the Voting Rights of
Certificates affected by a default or Event of Default hereunder, may waive such
default or Event of Default (other than an Event of Default set forth in Section
7.01(vi)); provided, however, that (a) a default or Event of Default under
clause (i) of Section 7.01 may be waived only by all of the Holders of
Certificates affected by such default or Event of Default and (b) no waiver
pursuant to this Section 7.04 shall affect the Holders of Certificates in the
manner set forth in the second paragraph of Section 11.01 or materially
adversely affect any non-consenting Certificateholder. Upon any such waiver of a

                                      123
<PAGE>

default or Event of Default by the Holders representing the requisite percentage
of Voting Rights of Certificates affected by such default or Event of Default,
such default or Event of Default shall cease to exist and shall be deemed to
have been remedied for every purpose hereunder. No such waiver shall extend to
any subsequent or other default or Event of Default or impair any right
consequent thereon except to the extent expressly so waived. The Master Servicer
shall give notice of any such waiver to the Rating Agencies.

         Section 7.05.     List of Certificateholders.

         Upon written request of three or more Certificateholders of record, for
purposes of communicating with other Certificateholders with respect to their
rights under this Agreement, the Trustee will afford such Certificateholders
access during business hours to the most recent list of Certificateholders held
by the Trustee.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

         Section 8.01.     Duties of Trustee.

         The Trustee, prior to the occurrence of an Event of Default and after
the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. If an Event of Default occurs, is continuing and has
not been waived, the Trustee shall exercise such of the rights and powers vested
in it by this Agreement, and use the same degree of care and skill in their
exercise as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs. Any permissive right of the Trustee enumerated in
this Agreement shall not be construed as a duty.

         The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them in accordance with the
requirements of this Agreement. If any such instrument is found not to conform
to the requirements of this Agreement in a material manner, the Trustee shall
take such action as it deems appropriate to have the instrument corrected, and
if the instrument is not corrected to the Trustee's satisfaction, the Trustee
will provide notice thereof to the Certificateholders. Notwithstanding the
foregoing, the Trustee shall not be responsible for the accuracy or content of
any resolution, certificate, statement, opinion, report, document, order or
other instrument furnished by the Master Servicer hereunder or any Opinion of
Counsel required hereunder.

         The Trustee shall prepare and file or cause to be filed on behalf of
the Trust Fund any tax return that is required with respect to REMIC 1, REMIC 2
and REMIC 3 pursuant to applicable federal, state or local tax laws.

         The Trustee covenants and agrees that it shall perform its obligations
hereunder in a manner so as to maintain the status of REMIC 1, REMIC 2 and REMIC
3 under the REMIC Provisions and to prevent the imposition of any federal, state
or local income, prohibited transaction, contribution or other tax on any of
REMIC 1, REMIC 2 or REMIC 3 to the extent that maintaining such status and
avoiding such taxes are within the control of the Trustee and are reasonably
within the scope of its duties under this Agreement.

         No provision of this Agreement shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct; provided, however, that:

         (i) Prior to the occurrence of an Event of Default, and after the
curing or waiver of all

                                      125
<PAGE>

such Events of Default which may have occurred, the duties and obligations of
the Trustee shall be determined solely by the express provisions of this
Agreement, the Trustee shall not be liable except for the performance of such
duties and obligations as are specifically set forth in this Agreement, no
implied covenants or obligations shall be read into this Agreement against the
Trustee and, in the absence of bad faith on the part of the Trustee, the Trustee
may conclusively rely, as to the truth of the statements and the correctness of
the opinions expressed therein, upon any certificates or opinions furnished to
the Trustee and conforming to the requirements of this Agreement;

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

         (iii) The Trustee shall not be liable with respect to any action taken,
suffered or omitted to be taken by it in good faith in accordance with the
direction of the Holders of Certificates entitled to at least 25% of the Voting
Rights relating to the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred
upon the Trustee, under this Agreement.

         Section 8.02.     Certain Matters Affecting the Trustee.

         Except as otherwise provided in Section 8.01:

         (a) The Trustee may conclusively rely upon and shall be fully protected
in acting or refraining from acting in reliance upon any resolution, Officers'
Certificate, certificate of auditors or any other certificate, statement,
instrument, opinion, report, notice, request, consent, order, appraisal, bond or
other paper or document reasonably believed by it to be genuine and to have been
signed or presented by the proper party or parties;

         (b) The Trustee may consult with counsel and any Opinion of Counsel
shall be full and complete authorization and protection in respect of any action
taken or suffered or omitted by it hereunder in good faith and in accordance
therewith;

         (c) The Trustee shall be under no obligation to exercise any of the
trusts or powers vested in it by this Agreement, other than its obligation to
give notice pursuant to this Agreement, or to institute, conduct or defend any
litigation hereunder or in relation hereto at the request, order or direction of
any of the Certificateholders, pursuant to the provisions of this Agreement,
unless such Certificateholders shall have offered to the Trustee security or
indemnity satisfactory to it against the costs, expenses and liabilities which
may be incurred therein or thereby; nothing contained herein shall, however,
relieve the Trustee of the obligation, upon the occurrence of an Event of
Default of which a Responsible Officer of the Trustee's corporate trust
department has actual knowledge (which has not been waived or cured), to
exercise such of the

                                      126
<PAGE>

rights and powers vested in it by this Agreement, and to use the same degree of
care and skill in their exercise as a prudent man would exercise or use under
the circumstances in the conduct of his own affairs;

         (d) The Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith and believed by it to be authorized or within the
discretion or rights or powers conferred upon it by this Agreement;

         (e) Prior to the occurrence of an Event of Default hereunder and after
the curing or waiver of all Events of Default which may have occurred, the
Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, approval, bond or other paper or document,
unless requested in writing to do so by the Holders of Certificates entitled to
at least 25% of the Voting Rights; provided, however, that if the payment within
a reasonable time to the Trustee of the costs, expenses or liabilities likely to
be incurred by it in the making of such investigation is, in the opinion of the
Trustee, reasonably assured to the Trustee by the security afforded to it by the
terms of this Agreement reasonable expense of every such examination shall be
paid by the Certificateholders requesting the investigation;

         (f) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents, nominees,
custodians or attorneys 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 Trustee shall not be required to give any bond or surety with
respect to the execution of the trust created hereby or the powers granted
hereunder; and

         (h) Whenever in the administration of the provisions of this Agreement
the Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking or suffering any action to be taken hereunder, such
matter (unless other evidence in respect thereof be herein specifically
prescribed) may, in the absence of gross negligence or bad faith on the part of
the Trustee, be deemed to be conclusively proved and established by a
certificate signed and delivered to the Trustee and such certificate, in the
absence of gross negligence or bad faith on the part of the Trustee, shall be
full warrant to the Trustee for any action taken, suffered or omitted by it
under the provisions of this Agreement upon the faith thereof.

         Section 8.03.     Trustee Not Liable for Certificates or Mortgage
                           Loans.

         The recitals contained herein and in the Certificates (other than the
signature of the Trustee, the authentication of the Trustee on the Certificates,
the acknowledgments of the Trustee contained in Article II) shall be taken as
the statements of the Company and the Trustee assumes no responsibility for
their correctness. The Trustee makes no representations or warranties as to

                                      127
<PAGE>

the validity or sufficiency of this Agreement or of the Certificates (other than
the signature and authentication of the Trustee on the Certificates) or of any
Mortgage Loan or related document, or of MERS or the MERS(R) System. The Trustee
shall not be accountable for the use or application by the Company of any of the
Certificates or of the proceeds of such Certificates, or for the use or
application of any funds paid to the Company or the Master Servicer in respect
of the Mortgage Loans or deposited in or withdrawn from the Custodial Account by
the Master Servicer.

         Section 8.04.     Trustee May Own Certificates.

         The Trustee in its individual or any other capacity (other than as
Trustee hereunder) may become the owner or pledgee of Certificates with the same
rights it would have if it were not Trustee and may otherwise deal with the
parties hereto.

         Section 8.05.     Trustee's Fees.

         On each Distribution Date, the Trustee shall be entitled to withdraw
from the Certificate Account as compensation hereunder the Trustee Fees. Such
compensation (which shall not be limited by any provision of law in regard to
the compensation of a trustee of an express trust) shall be paid for all
services rendered by it (except as otherwise reimbursed by the Seller pursuant
to a separate fee letter between the Seller and the Trustee) in the execution of
the trusts hereby created and in the exercise and performance of any of the
powers and duties hereunder or of the Trustee. Except as otherwise provided in
this Agreement, the Trustee and any director, officer, employee or agent of the
Trustee shall be indemnified and held harmless by the Trust Fund against any
claim, loss, liability, fee or expense incurred in connection with any Event of
Default, any breach of this Agreement or any claim or legal action (including
any pending or threatened claim or legal action) relating to the acceptance or
administration of its trusts hereunder or the Trustee's performance under the
Certificates, other than any claim, loss, liability or expense (i) sustained in
connection with this Agreement related to the willful misfeasance, bad faith or
negligence of the Master Servicer in the performance of its duties hereunder or
(ii) incurred in connection with a breach constituting willful misfeasance, bad
faith or negligence of the Trustee in the performance of its duties hereunder or
by reason of reckless disregard of its obligations and duties hereunder.

         The Master Servicer shall indemnify the Trustee and any director,
officer, employee or agent of the Trustee against any such claim or legal action
(including any pending or threatened claim or legal action), loss, liability,
fee or expense that may be sustained in connection with this Agreement related
to the willful misfeasance, bad faith, or negligence in the performance of the
Master Servicer's duties hereunder.

         The provisions of this Section 8.05 shall survive the resignation or
removal of the Trustee or the termination of this Agreement.

                                      128
<PAGE>

         Section 8.06.     Eligibility Requirements for Trustee.

         The Trustee hereunder shall at all times be a corporation or a national
banking association organized and doing business under the laws of any state or
the United States of America or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having a combined capital and surplus
of at least $50,000,000 and subject to supervision or examination by federal or
state authority. In addition, the Trustee shall at all times be acceptable to
the Rating Agency rating the Certificates. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 8.07.
The corporation or national banking association serving as Trustee may have
normal banking and trust relationships with the Seller and their affiliates or
the Master Servicer and its affiliates; provided, however, that such corporation
cannot be an affiliate of the Master Servicer other than the Trustee in its role
as successor to the Master Servicer.

         Section 8.07.     Resignation and Removal of the Trustee.

         The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice thereof to the Master Servicer; with a
copy to the Rating Agencies; provided, that such resignation shall not be
effective until a successor trustee is appointed and accepts appointment in
accordance with the following provisions; provided, however, that the resigning
Trustee shall not resign and be discharged from the trusts hereby created until
such time as the Rating Agency rating the Certificates approves the successor
trustee. Upon receiving such notice of resignation, the Master Servicer shall
promptly appoint a successor trustee who meets the eligibility requirements of
Section 8.06 by written instrument, in triplicate, one copy of which instrument
shall be delivered to each of the resigning Trustee and to the successor
trustee. If no successor trustee shall have been so appointed and have accepted
appointment within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor trustee.

         If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request therefor by the Master Servicer, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of

                                      129
<PAGE>

rehabilitation, conservation or liquidation, the Master Servicer may remove the
Trustee and appoint a successor trustee who meets the eligibility requirements
of Section 8.06 by written instrument, in triplicate, which instrument shall be
delivered to the Trustee so removed and to the successor trustee.

         The Holders of Certificates entitled to at least 51% of the Voting
Rights, may at any time remove the Trustee and appoint a successor trustee by
written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized, one complete set of which instruments
shall be delivered to the Master Servicer, one complete set to the Trustee so
removed and one complete set to the successor so appointed. A copy of such
instrument shall be delivered to the Certificateholders and the Company by the
Master Servicer.

         Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor trustee as
provided in Section 8.08.

         Section 8.08.     Successor Trustee.

         Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Master Servicer and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with the like effect as if originally named as trustee
herein. The predecessor trustee shall after payment of its outstanding fees and
expenses, promptly deliver to the successor trustee all assets and records of
the Trust Fund held by it hereunder, and the Master Servicer and the predecessor
trustee shall execute and deliver all such instruments and do such other things
as may reasonably be required for more fully and certainly vesting and
confirming in the successor trustee all such rights, powers, duties and
obligations.

         No successor trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.06.

         Upon acceptance of appointment by a successor trustee as provided in
this Section, the Master Servicer shall mail notice of the succession of such
trustee hereunder to all Holders of Certificates at their addresses as shown in
the Certificate Register. If the Master Servicer fails to mail such notice
within ten days after acceptance of appointment by the successor trustee, the
successor trustee shall cause such notice to be mailed at the expense of the
Master Servicer.

         Section 8.09.     Merger or Consolidation of Trustee.

                                      130
<PAGE>

         Any state bank or trust company or corporation or national banking
association into which the Trustee may be merged or converted or with which it
may be consolidated or any state bank or trust company or national banking
association resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any state bank or trust company or corporation or
national banking association succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder, provided such state bank or trust company or corporation or national
banking association shall be eligible under the provisions of Section 8.06
without the execution or filing of any paper or any further act on the part of
any of the parties hereto, anything herein to the contrary notwithstanding.

         Section 8.10.     Appointment of Co-Trustee or Separate Trustee.

         Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Fund or property securing the same may at the time be located, the
Master Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
8.10, such powers, duties, obligations, rights and trusts as the Master Servicer
and the Trustee may consider necessary or desirable. If the Master Servicer
shall not have joined in such appointment within 15 days after the receipt by it
of a request so to do, or in case an Event of Default shall have occurred and be
continuing, the Trustee alone shall have the power to make such appointment
without the Master Servicer. No co-trustee or separate trustee hereunder shall
be required to meet the terms of eligibility as a successor trustee under
Section 8.06 hereunder and no notice to Holders of Certificates of the
appointment of co-trustee(s) or separate trustee(s) shall be required under
Section 8.08 hereof.

         In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.10, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred or such
co-trustee shall be conferred or imposed upon and exercised or performed by the
Trustee and such separate trustee or co-trustee jointly, except to the extent
that under any law of any jurisdiction in which any particular act or acts are
to be performed (whether as Trustee hereunder or as successor to the Master
Servicer hereunder), the 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 Fund or any portion thereof in any
such jurisdiction) shall be exercised and performed by such separate trustee or
co-trustee at the direction of the Trustee.

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

                                      131
<PAGE>

Agreement and the conditions of this Article VIII. Each separate trustee and
co-trustee, upon its acceptance of the trusts conferred, shall be vested with
the estates or property specified in its instrument of appointment, either
jointly with the Trustee or separately, as may be provided therein, subject to
all the provisions of this Agreement, specifically including every provision of
this Agreement relating to the conduct of, affecting the liability of, or
affording protection to, the Trustee. Every such instrument shall be filed with
the Trustee.

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

                                   ARTICLE IX

                                   TERMINATION

         Section 9.01.     Termination Upon Repurchase or Liquidation of All
                           Mortgage Loans or upon Purchase of Certificates.

         (a) Subject to Section 9.03, the respective obligations and
responsibilities of the Company, the Master Servicer and the Trustee created
hereby (other than the obligations of the Master Servicer to the Trustee
pursuant to Section 8.05 and of the Master Servicer to provide for and the
Trustee to make payments to Certificateholders as hereafter set forth) shall
terminate upon payment to the Certificateholders of all amounts held by or on
behalf of the Trustee and required to be paid to them hereunder following the
earlier to occur of (i) the repurchase by the Holder of a 50.01% or greater
Percentage Interest in the Class C Certificates (the "Majority Class C
Certificateholders") or its designee of all Mortgage Loans and each REO Property
in respect thereof remaining in the Trust Fund at a price equal to (a) 100% of
the unpaid principal balance of each Mortgage Loan (other than one as to which a
REO Property was acquired) on the day of repurchase together with accrued
interest on such unpaid principal balance at the Net Mortgage Rate to the first
day of the month in which the proceeds of such repurchase are to be distributed,
plus (b) the appraised value of any REO Property (but not more than the unpaid
principal balance of the related Mortgage Loan, together with accrued interest
on that balance at the Net Mortgage Rate to the first day of the month such
repurchase price is distributed), less the good faith estimate of the Majority
Class C Certificateholders of liquidation expenses to be incurred in connection
with its disposal thereof, such appraisal to be conducted by an appraiser
mutually agreed upon by the Majority Class C Certificateholders and the Trustee
at the expense of the Master Servicer, and (ii) the final payment or other
liquidation (or any Advance with respect thereto) of the last Mortgage Loan
remaining in the Trust Fund (or the disposition of all REO Property in respect
thereof); provided, however, that in no event shall the trust created hereby
continue beyond the earlier of (i) the Distribution Date occurring in April 2032
and (ii) the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late ambassador of the United States to
the Court of St. James, living on the date hereof, and provided further, that
the purchase price set forth above shall be increased as is necessary, as
determined by the Majority Class C Certificateholders, to avoid disqualification
of any of REMIC 1, REMIC 2 or REMIC 3 as a REMIC. In the case of any repurchase
by the Majority Class C Certificateholders pursuant to clause (i), the Master
Servicer shall exercise reasonable efforts to cooperate fully with the Trustee
in effecting such repurchase and the transfer of the Mortgage Loans and related
Mortgage Files and related records to the Majority Class C Certificateholders.

         The right of the Majority Class C Certificateholders or its designee to
repurchase all Mortgage Loans pursuant to (i) above shall be conditioned upon
the aggregate Stated Principal Balance of such Mortgage Loans at the time of any
such repurchase aggregating an amount equal

                                      133
<PAGE>

to or less than 10% of the sum of the aggregate Stated Principal Balance of the
Initial Mortgage Loans at the Cut-off Date and the Original Pre-Funded Amount.
If such right is exercised, the Majority Class C Certificateholders upon such
repurchase shall provide to the Trustee, notice of such exercise prior to the
Determination Date in the month preceding the month of purchase and the
certification required by Section 3.16.

         Written notice of any termination, specifying the Distribution Date
upon which the Certificateholders may surrender their Certificates to the
Trustee for payment of the final distribution and cancellation, shall be given
promptly by the Trustee by letter to the Certificateholders mailed (a) in the
event such notice is given in connection with the Majority Class C
Certificateholder's election to repurchase, not earlier than the 15th day and
not later than the 25th day of the month next preceding the month of such final
distribution or (b) otherwise during the month of such final distribution on or
before the Determination Date in such month, in each case specifying (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of Certificates at the office of the Trustee therein
designated, (ii) the amount of any such final payment and (iii) that the Record
Date otherwise applicable to such Distribution Date is not applicable, payments
being made only upon presentation and surrender of the Certificates at the
office of the Trustee therein specified. In the event such notice is given in
connection with the Majority Class C Certificateholder or its designee's
election to repurchase, the Majority Class C Certificateholder or its designee
shall deliver to the Trustee for deposit in the Certificate Account on the
Business Day immediately preceding the Distribution Date specified in such
notice an amount equal to the above-described repurchase price payable out of
its own funds. Upon presentation and surrender of the Certificates by the
Certificateholders, the Trustee shall first, pay itself the Trustee's Fees for
such Distribution Date and any other amounts owing to the Trustee under this
Agreement, and second, distribute to the Certificateholders (i) the amount
otherwise distributable on such Distribution Date, if not in connection with the
Majority Class C Certificateholder's election to repurchase, or (ii) if the
Majority Class C Certificateholder elected to so repurchase, an amount
determined as follows: with respect to each Regular Certificate (other than the
Class A-IO Certificates), the outstanding Certificate Principal Balance thereof,
plus with respect to each Regular Certificate (other than the Class P
Certificates), one month's interest thereon at the applicable Pass-Through Rate
and any Unpaid Interest Shortfall Amount, plus with respect to each Mezzanine
Certificate, any unpaid Allocated Realized Loss Amount; and with respect to the
Class R Certificates, the Percentage Interest evidenced thereby multiplied by
the difference, if any, between the above described repurchase price and the
aggregate amount to be distributed to the Holders of the Regular Certificates,
subject to the priorities set forth in Section 4.01. Notwithstanding the
foregoing, by acceptance of the Class R Certificates, the Holders of the Class R
Certificates agree, in connection with any termination hereunder, to assign and
transfer any amounts received in respect of such termination to the Holders of
the Class C Certificates and to pay any such amounts to the Holders of the Class
C Certificates. Upon certification to the Trustee by a Servicing Officer,
following such final deposit, the Trustee shall promptly release the Mortgage
Files as directed by the Majority Class C Certificateholder for the remaining
Mortgage Loans,

                                      134
<PAGE>

and the Trustee shall execute all assignments, endorsements and other
instruments required by the Majority Class C Certificateholder as being
necessary to effectuate such transfer.

         In the event that all of the Certificateholders shall not surrender
their Certificates for cancellation within six months after the time specified
in the above-mentioned notice, the Trustee shall give a second notice to the
remaining Certificateholders to surrender their Certificates for cancellation
and receive the final distribution with respect thereto. If within six months
after the second notice all of the Certificates shall not have been surrendered
for cancellation, the Trustee shall take reasonable steps as directed by the
Company in writing, or appoint an agent to take reasonable steps, to contact the
remaining Certificateholders concerning surrender of their Certificates, and the
cost thereof shall be paid out of the funds and other assets which remain
subject hereto. If within nine months after the second notice all the
Certificates shall not have been surrendered for cancellation, the Class R
Certificateholders shall be entitled to all unclaimed funds and other assets
which remain subject hereto.

         Section 9.02.     Termination of REMIC 2 and REMIC 3.

         REMIC 2 shall be terminated on the earlier of the Final Distribution
Date and the date on which it is deemed to receive the last deemed distributions
on the REMIC 1 Regular Interests and the last distribution due on the REMIC 2
Regular Interests and the Class R Certificates (in respect of the Class R-2
Interest) is made. REMIC 3 shall be terminated on the earlier of the Final
Distribution Date and the date on which it is deemed to receive the last deemed
distributions on the REMIC 2 Regular Interests and the last distribution due on
the Regular Certificates and the Class R Certificates (in respect of the Class
R-3 Interest) is made.

         Section 9.03.     Additional Termination Requirements.

         (a) In the event the Majority Class C Certificateholder repurchases the
Mortgage Loans as provided in Section 9.01, the Trust Fund shall be terminated
in accordance with the following additional requirements, unless the Majority
Class C Certificateholder, at its own expense, obtains for the Trustee an
Opinion of Counsel to the effect that the failure of the Trust Fund to comply
with the requirements of this Section 9.03 will not (i) result in the imposition
on the Trust of taxes on "prohibited transactions," as described in Section 860F
of the Code, or (ii) cause either REMIC 1, REMIC 2 or REMIC 3 to fail to qualify
as a REMIC at any time that any Certificate is outstanding:

                  (i) The Trustee shall establish a 90-day liquidation period
for REMIC 1, REMIC 2 and REMIC 3, as the case may be, and specify the first day
of such period in a statement attached to the Trust Fund's final Tax Return
pursuant to Treasury regulations Section 1.860F-1. The Trustee also shall
satisfy all of the requirements of a qualified liquidation for REMIC 1, REMIC 2
and REMIC 3, as the case may be, under Section 860F of the Code and regulations
thereunder; and

                                      135
<PAGE>

                  (ii) The Majority Class C Certificateholder shall notify the
Trustee at the commencement of such 90-day liquidation period and, at or prior
to the time of making of the final payment on the Certificates, the Trustee
shall sell or otherwise dispose of all of the remaining assets of the Trust Fund
in accordance with the terms hereof.

         (b) Each Holder of a Certificate and the Trustee hereby irrevocably
approves and appoints the Master Servicer as its attorney-in-fact to adopt a
plan of complete liquidation for REMIC 1, REMIC 2 and REMIC 3 at the expense of
the Trust Fund in accordance with the terms and conditions of this Agreement.

                                REMIC PROVISIONS

         Section 10.01.    REMIC Administration.

         (a) The Trustee shall make an election to treat the Trust Fund as three
REMICs under the Code and, if necessary, under applicable state law. Each such
election will be made on Form 1066 or other appropriate federal tax or
information return (including Form 8811) or any appropriate state return for the
taxable year ending on the last day of the calendar year in which the
Certificates are issued. For the purposes of the REMIC elections in respect of
the Trust Fund, (i) the Class R-1 Interest will constitute the sole class of
"residual interest" in REMIC 1, (ii) the Class R-2 Interest will constitute the
sole class of "residual interest" in REMIC 2, and (iii) the Class R-3 Interest
will constitute the sole class of "residual interest" in REMIC 3, and the
Regular Certificates shall be designated as the "regular interests" in REMIC 3.
The Master Servicer and the Trustee shall not permit the creation of any
"interests" (within the meaning of Section 860G of the Code) in REMIC 1, REMIC 2
or REMIC 3 other than the REMIC 1 Regular Interests and the Class R-1 Interest
(in the case of REMIC 1), the REMIC 2 Regular Interests and the Class R-2
Interest (in the case of REMIC 2), and the Regular Certificates and the Class
R-3 Interest (in the case of REMIC 3). The Trustee will apply for an Employee
Identification Number from the IRS via form SS-4 or any other acceptable method
for each of REMIC 1, REMIC 2 and REMIC 3.

         (b) The Closing Date is hereby designated as the "startup day" of the
Trust Fund within the meaning of Section 860G(a)(9) of the Code.

         (c) The Trustee shall pay out of its own funds, without any right of
reimbursement, any and all expenses relating to any tax audit of the REMICs
(including, but not limited to, any professional fees or any administrative or
judicial proceedings with respect to the REMICs that involve the Internal
Revenue Service or state tax authorities), other than the expense of obtaining
any tax-related Opinion of Counsel except as specified herein. The Trustee, as
agent for the REMICs' tax matters person, shall (i) act on behalf of the REMICs
in relation to any tax matter or controversy involving the Trust Fund and (ii)
represent the Trust Fund in any administrative or judicial proceeding relating
to an examination or audit by any governmental taxing authority with respect
thereto. By their acceptance thereof, the holder of the largest Percentage
Interest of the Class R Certificates hereby agrees to irrevocably appoint the
Trustee or an Affiliate as its agent to perform all of the duties of the tax
matters person for the REMICs.

         (d) The Trustee shall prepare, sign and file all of the Tax Returns
(including Form 8811, which must be filed within 30 days of the Closing Date) in
respect of the REMICs created hereunder. The expenses of preparing and filing
such returns shall be borne by the Trustee without any right of reimbursement
therefor. The Master Servicer shall provide on a timely basis

                                      137
<PAGE>

to the Trustee or its designee such information with respect to the assets of
the REMICs as is in its possession and reasonably required by the Trustee to
enable it to perform its obligations under this Article X.

         (e) The Trustee shall perform on behalf of the REMICs all reporting and
other tax compliance duties that are the responsibility of the REMICs under the
Code, the REMIC Provisions or other compliance guidance issued by the Internal
Revenue Service or any state or local taxing authority. Among its other duties,
as required by the Code, the REMIC Provisions or other such compliance guidance,
the Trustee shall provide (i) to any Transferor of a Class R Certificate such
information as is necessary for the application of any tax relating to the
transfer of a Class R Certificate to any Person who is not a Permitted
Transferee, (ii) to the Certificateholders such information or reports as are
required by the Code or the REMIC Provisions including reports relating to
interest, original issue discount and market discount or premium (using the
Prepayment Assumption as required) and (iii) to the Internal Revenue Service the
name, title, address and telephone number of the person who will serve as the
representative of the REMICs. The Master Servicer shall provide on a timely
basis to the Trustee such information with respect to the assets of the REMICs,
including, without limitation, the Mortgage Loans, as is in its possession and
reasonably required by the Trustee to enable it to perform its obligations under
this subsection. In addition, the Company shall provide or cause to be provided
to the Trustee, within ten (10) days after the Closing Date, all information or
data that the Trustee reasonably determines to be relevant for tax purposes as
to the valuations and issue prices of the Certificates, including, without
limitation, the price, yield, prepayment assumption and projected cash flow of
the Certificates.

         (f) The Trustee shall take such action and shall cause the REMICs
created hereunder to take such action as shall be necessary to create or
maintain the status thereof as REMICs under the REMIC Provisions (and the Master
Servicer shall assist it, to the extent reasonably requested by it). The Trustee
shall not take any action, cause the Trust Fund to take any action or fail to
take (or fail to cause to be taken) any action that, under the REMIC Provisions,
if taken or not taken, as the case may be, could (i) endanger the status of the
REMIC 1, REMIC 2 or REMIC 3 as REMICs or (ii) result in the imposition of a tax
upon the REMICs (including but not limited to the tax on prohibited transactions
as defined in Section 860F(a)(2) of the Code and the tax on contributions to a
REMIC set forth in Section 860G(d) of the Code) (either such event, an "Adverse
REMIC Event") unless the Trustee has received an Opinion of Counsel, addressed
to the Trustee (at the expense of the party seeking to take such action but in
no event at the expense of the Trustee) to the effect that the contemplated
action will not, with respect to the REMICs created hereunder, endanger such
status or result in the imposition of such a tax, nor shall the Master Servicer
take or fail to take any action (whether or not authorized hereunder) as to
which the Trustee has advised it in writing that it has received an Opinion of
Counsel to the effect that an Adverse REMIC Event could occur with respect to
such action. In addition, prior to taking any action with respect to the REMICs
or the assets of the REMICs, or causing the REMICs to take any action, which is
not contemplated under the terms of this Agreement, the Master

                                      138
<PAGE>

Servicer will consult with the Trustee or its designee, in writing, with respect
to whether such action could cause an Adverse REMIC Event to occur with respect
to the Trust Fund, and the Master Servicer shall not take any such action or
cause the Trust Fund to take any such action as to which the Trustee has advised
it in writing that an Adverse REMIC Event could occur. The Trustee may consult
with counsel to make such written advice, and the cost of same shall be borne by
the party seeking to take the action not permitted by this Agreement, but in no
event shall such cost be an expense of the Trustee. At all times as may be
required by the Code, the Trustee will ensure that substantially all of the
assets of the REMICs created hereunder will consist of "qualified mortgages" as
defined in Section 860G(a)(3) of the Code and "permitted investments" as defined
in Section 860G(a)(5) of the Code.

         (g) In the event that any tax is imposed on "prohibited transactions"
of the REMICs created hereunder as defined in Section 860F(a)(2) of the Code, on
the "net income from foreclosure property" of the REMICs as defined in Section
860G(c) of the Code, on any contributions to the REMICs after the Startup Day
therefor pursuant to Section 860G(d) of the Code, or any other tax is imposed by
the Code or any applicable provisions of state or local tax laws, such tax shall
be charged (i) to the Trustee pursuant to Section 10.03 hereof, if such tax
arises out of or results from a breach by the Trustee of any of its obligations
under this Article X, (ii) to the Master Servicer pursuant to Section 10.03
hereof, if such tax arises out of or results from a breach by the Master
Servicer of any of its obligations under Article III or this Article X, or
otherwise, (iii) to the Master Servicer as provided in Section 3.05 and (iv)
against amounts on deposit in the Certificate Account and shall be paid by
withdrawal therefrom to the extent not required to be paid by the Master
Servicer or the Trustee pursuant to another provision of this Agreement.

         (h) On or before April 15 of each calendar year, commencing April 15,
2003, the Trustee shall deliver to the Master Servicer and the Rating Agency a
Certificate from a Responsible Officer of the Trustee stating the Trustee's
compliance with this Article X.

         (i) The Trustee shall, for federal income tax purposes, maintain books
and records with respect to the REMICs on a calendar year and on an accrual
basis.

         (j) Following the Startup Day, the Trustee shall not accept any
contributions of assets to the REMICs other than in connection with any
Qualified Substitute Mortgage Loan delivered in accordance with Section 2.04
unless it shall have received an Opinion of Counsel to the effect that the
inclusion of such assets in the REMICs will not cause the REMIC 1, REMIC 2 or
REMIC 3 to fail to qualify as REMICs at any time that any Certificates are
outstanding or subject either REMIC 1, REMIC 2 or REMIC 3 to any tax under the
REMIC Provisions or other applicable provisions of federal, state and local law
or ordinances.

         (k) Neither the Trustee nor the Master Servicer shall enter into any
arrangement by which the REMICs will receive a fee or other compensation for
services nor permit the REMICs

                                      139
<PAGE>

to receive any income from assets other than "qualified mortgages" as defined in
Section 860G(a)(3) of the Code or "permitted investments" as defined in Section
860G(a)(5) of the Code.

         Section 10.02.    Prohibited Transactions and Activities.

         None of the Company, the Master Servicer or the Trustee shall sell,
dispose of or substitute for any of the Mortgage Loans (except in connection
with (i) the foreclosure of a Mortgage Loan, including but not limited to, the
acquisition or sale of a Mortgaged Property acquired by deed in lieu of
foreclosure, (ii) the bankruptcy of the Trust Fund, (iii) the termination of
REMIC 1, REMIC 2 or REMIC 3 pursuant to Article IX of this Agreement, (iv) a
substitution pursuant to Article II of this Agreement or (v) a purchase of
Mortgage Loans pursuant to Article II or III of this Agreement), nor acquire any
assets for the Trust Fund (other than REO Property acquired in respect of a
defaulted Mortgage Loan), nor sell or dispose of any investments in the
Custodial Account or the Certificate Account for gain, nor accept any
contributions to the REMICs after the Closing Date (other than a Qualified
Substitute Mortgage Loan delivered in accordance with Section 2.04), unless it
has received an Opinion of Counsel, addressed to the Trustee (at the expense of
the party seeking to cause such sale, disposition, substitution, acquisition or
contribution but in no event at the expense of the Trustee) that such sale,
disposition, substitution, acquisition or contribution will not (a) affect
adversely the status of REMIC 1, REMIC 2 or REMIC 3 as REMICs or (b) cause the
Trust Fund to be subject to a tax on "prohibited transactions" or
"contributions" pursuant to the REMIC Provisions.

         Section 10.03.    Master Servicer and Trustee Indemnification.

         (a) The Trustee agrees to indemnify the Trust Fund, the Company, and
the Master Servicer for any taxes and costs including, without limitation, any
reasonable attorneys' fees imposed on or incurred by the Trust Fund, the Company
or the Master Servicer, as a result of a breach of the Trustee's covenants set
forth in this Article X.

         (b) The Master Servicer agrees to indemnify the Trust Fund, the Company
and the Trustee for any taxes and costs including, without limitation, any
reasonable attorneys' fees imposed on or incurred by the Trust Fund, the Company
or the Trustee, as a result of a breach of the Master Servicer's covenants set
forth in Article III or this Article X, in each case with respect to compliance
with the REMIC Provisions.

                            MISCELLANEOUS PROVISIONS

         Section 11.01.    Amendment.

statute or any temporary or final regulation, revenue ruling, revenue procedure
or other written official announcement or interpretation relating to federal
income tax laws or any proposed such action which, if made effective, would

least 66-2/3% of the Voting Rights for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this Agreement
or of modifying in any manner the rights of the Holders of Certificates;
provided, however, that no such amendment shall (i) reduce in any manner the

         Promptly after the execution of any such amendment the Trustee shall
furnish a copy of such amendment or a written statement describing the amendment
to each Certificateholder, with a copy to the Rating Agencies.

         It shall not be necessary for the consent of Certificateholders under
this Section 11.01 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

         Prior to executing any amendment pursuant to this Section, the Trustee
shall be entitled to receive an Opinion of Counsel (provided by the Person
requesting such amendment) to the effect that such amendment is authorized or
permitted by this Agreement. The cost of any Opinion of Counsel delivered
pursuant to this Section 11.01 shall be an expense of the party requesting such

Master Servicer at the expense of the Certificateholders, but only upon
direction of the Company accompanied by an Opinion of Counsel to the effect that
such recordation materially and beneficially affects the interests of the
Certificateholders.

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

Agreement or the Trust Fund, nor entitle such Certificateholder's legal
representatives or heirs to claim an accounting or to take any action or
proceeding in any court for a partition or winding up of the Trust Fund, nor
otherwise affect the rights, obligations and liabilities of the parties hereto
or any of them.

         No Certificateholder shall have any right to vote (except as expressly
provided for herein) or in any manner otherwise control the operation and
management of the Trust Fund, or the obligations of the parties hereto, nor

any liability to any third party by reason of any action taken by the parties to
this Agreement pursuant to any provision hereof.

         No Certificateholder shall have any right by virtue of any provision of
this Agreement to institute any suit, action or proceeding in equity or at law
upon or under or with respect to this Agreement, unless such Holder previously
shall have given to the Trustee a notice of an Event of Default, or of a default
by the Seller or the Trustee in the performance of any obligation hereunder, and
of the continuance thereof, as hereinbefore provided, and unless also the
Holders of Certificates entitled to at least 51% of the Voting Rights shall have
made written request upon the Trustee to institute such action, suit or
proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs, expenses
and liabilities to be incurred therein or thereby, and the Trustee, for 60 days
after its receipt of such notice, request and offer of indemnity, shall have
neglected or refused to institute any such action, suit or proceeding. It is
understood and intended, and expressly covenanted by each Certificateholder with
every other Certificateholder and the Trustee, that no one or more Holders of
Certificates shall have any right in any manner whatever by virtue of any
provision of this Agreement to affect, disturb or prejudice the rights of the
Holders of any other of such Certificates, or to obtain or seek to obtain
priority over or preference to any other such Holder, or to enforce any right
under this Agreement, except in the manner herein provided and for the equal,
ratable and common benefit of all Certificateholders. For the protection and
enforcement of the provisions of this Section, each and every Certificateholder
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

         evidencing a percentage interest in the distributions allocable to the
         Class A- ___ Certificates with respect to a Trust Fund consisting
         primarily of a pool of conforming one- to four-family fixed-rate first
         lien mortgage loans formed and sold by IMPAC SECURED ASSETS CORP.

         This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Impac Secured Assets
Corp., the Master Servicer, the Trustee referred to below or any of their
affiliates. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental agency or instrumentality or by Impac
Secured Assets Corp., the Master Servicer, the Trustee or any of their
affiliates. None of the Company, the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

         This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial [Certificate Principal Balance] [Notional Amount] of this Certificate by
the aggregate Initial [Certificate Principal Balance] [Notional Amount] of all
Class A-____ Certificates, both as specified above) in certain distributions
with respect to the Trust Fund consisting primarily of an interest in a pool of
conventional one- to four-family fixed-rate first lien mortgage loans (the
"Mortgage Loans"), formed and sold by Impac Secured Assets Corp. (hereinafter
called the "Company," which term includes any successor entity under the
Agreement

                                       A-2

referred to below). The Trust Fund was created pursuant to a Pooling and
Servicing Agreement dated as specified above (the "Agreement") among the
Company, the Master Servicer and Bankers Trust Company of California, N.A., as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
immediately preceding the month of such Distribution Date (the "Record Date"),
from the Available Distribution Amount in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount of [interest
and] [principal], if any, required to be distributed to Holders of Class
A-____Certificates on such Distribution Date.

         Distributions on this Certificate will be made either by the Trustee or
by a Paying Agent appointed by the Trustee either in immediately available funds
(by wire transfer or otherwise) for the account of the Person entitled thereto
if such Person shall have so notified the Trustee or such Paying Agent at least
5 Business Days prior to the related Record Date, or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

         Notwithstanding the above, the final distribution on this Certificate
will be made after due notice of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose in the City and State of New York. The Initial
[Certificate Principal Balance] [Notional Amount] of this Certificate is set
forth above. The [Certificate Principal Balance] [Notional Amount] hereof will
be reduced to the extent of [distributions allocable to principal and] any
Realized Losses allocable hereto.

         This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

         The Certificates are limited in right of payment to certain collections
and recoveries respecting the Mortgage Loans, all as more specifically set forth
herein and in the Agreement. In the event Master Servicer funds are advanced
with respect to any Mortgage Loan, such advance is reimbursable to the Master
Servicer, to the extent provided in the Agreement, from related recoveries on
such Mortgage Loan or from other cash that would have been distributable to
Certificateholders.

                                       A-3

<PAGE>

         As provided in the Agreement, withdrawals from the Custodial Account
and/or the Certificate Account created for the benefit of Certificateholders may
be made by the Master Servicer from time to time for purposes other than
distributions to Certificateholders, such purposes including without limitation
reimbursement to the Trustee, the Company and the Master Servicer of advances
made, or certain expenses incurred, by either of them.

         The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon the Certificate. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same Class and aggregate Percentage Interest will be issued to the
designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in Classes and in denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of authorized denominations
evidencing the same Class and aggregate Percentage Interest, as requested by the
Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Company, the Master Servicer, the Trustee and the Certificate
Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the
Master Servicer, the Trustee nor any such agent shall be affected by notice to
the contrary.

         This Certificate shall be governed by and construed in accordance with
the laws of the State of New York.

         The obligations created by the Agreement in respect of the Certificates
and the Trust Fund created thereby shall terminate upon the payment to
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the purchase by the Holder of at least 50.01% Percentage Interest in the
Class C Certificates (the "Majority Class C Certificateholder") from the Trust
Fund of all remaining Mortgage Loans and each REO Property in respect thereof
remaining in the Trust Fund, thereby effecting early retirement of the
Certificates and (ii) the final payment or other liquidation (or any Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust Fund (or
the disposition of all REO Property in respect thereof). The Agreement permits,
but does not require, the Majority Class C Certificateholder to purchase at a
price determined as provided in the Agreement all remaining Mortgage Loans and
all REO Property; provided, that any such option may only be exercised if the
aggregate Stated Principal Balance of the Mortgage Loans as of the Distribution
Date upon which the proceeds of any such purchase are distributed is less than
ten percent of the aggregate Stated Principal Balance of the Mortgage Loans at

                                  Series 2002-1

         evidencing a percentage interest in any distributions allocable to the
         Class [M-__] [B] Certificates with respect to the Trust Fund consisting
         primarily of a pool of conforming one- to four-family fixed-rate first
         lien mortgage loans formed and sold by IMPAC SECURED ASSETS CORP.

         This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Impac Secured Assets
Corp., the Master Servicer, the Trustee referred to below or any of their
affiliates. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental agency or instrumentality or by Impac
Secured Assets Corp., the Master Servicer, the Trustee or any of their
affiliates. None of the Company, the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other obligation
secured by or payable from payments on the Certificates.

         This certifies that Cede & Co. is the registered owner of the
Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial Certificate Principal Balance of this Certificate by the aggregate
Initial Certificate Principal Balance of all Class [M-_][B] Certificates, both
as specified above) in certain distributions with respect to a Trust Fund
consisting primarily of a pool of conforming one- to four-family fixed-rate
first lien mortgage loans (the "Mortgage Loans"), formed and sold by Impac
Secured Assets Corp. (hereinafter called the "Company," which term includes any
successor entity under the Agreement referred to below). The Trust Fund was
created pursuant to a Pooling and Servicing Agreement dated as specified above
(the "Agreement") among

                                      B-1-2

<PAGE>

the Company, the Master Servicer and Bankers Trust Company of California, N.A.,
as trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
immediately preceding the month of such Distribution Date (the "Record Date"),
from the Available Distribution Amount in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount (of interest
[and principal], if any) required to be distributed to Holders of Class
[M-__][B] Certificates on such Distribution Date.

         Distributions on this Certificate will be made either by the Trustee or
by a Paying Agent appointed by the Trustee either in immediately available funds
(by wire transfer or otherwise) for the account of the Person entitled thereto
if such Person shall have so notified the Trustee or such Paying Agent at least
5 Business Days prior to the related Record Date, or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

         Notwithstanding the above, the final distribution on this Certificate
will be made after due notice of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose in the City and State of New York. The Initial
Certificate Principal Balance of this Certificate is set forth above. The
Certificate Principal Balance hereof will be reduced to the extent of [the
distributions allocable to principal and] any Realized Losses allocable hereto.

         This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

         The Certificates are limited in right of payment to certain collections
and recoveries respecting the Mortgage Loans, all as more specifically set forth
herein and in the Agreement. In the event Master Servicer funds are advanced
with respect to any Mortgage Loan, such advance is reimbursable to the Master
Servicer, to the extent provided in the Agreement, from related recoveries on
such Mortgage Loan or from other cash that would have been distributable to
Certificateholders.

         As provided in the Agreement, withdrawals from the Custodial Account
and/or the Certificate Account created for the benefit of Certificateholders may
be made by the Master Servicer from time to time for purposes other than
distributions to Certificateholders, such purposes including

                                      B-1-3

<PAGE>

without limitation reimbursement to the Trustee, the Company and the Master
Servicer of advances made, or certain expenses incurred, by either of them.

         The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon the Certificate. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same Class and aggregate Percentage Interest will be issued to the
designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in Classes and in denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of authorized denominations
evidencing the same Class and aggregate Percentage Interest, as requested by the
Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Company, the Master Servicer, the Trustee and the Certificate
Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the
Master Servicer, the Trustee nor any such agent shall be affected by notice to
the contrary.

         This Certificate shall be governed by and construed in accordance with
the laws of the State of New York.

         The obligations created by the Agreement in respect of the Certificates
and the Trust Fund created thereby shall terminate upon the payment to
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the purchase by the Holder of at least 50.01% Percentage Interest in the
Class C Certificates (the "Majority Class C Certificateholder") from the Trust
Fund of all remaining Mortgage Loans and each REO Property in respect thereof
remaining in the Trust Fund, thereby effecting early retirement of the
Certificates and (ii) the final payment or other liquidation (or any Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust Fund (or
the disposition of all REO Property in respect thereof). The Agreement permits,
but does not require, the Majority Class C Certificateholder to purchase at a
price determined as provided in the Agreement all remaining Mortgage Loans and
all REO Property; provided, that any such option may only be exercised if the
aggregate Stated Principal Balance of the Mortgage Loans as of the Distribution
Date upon which the proceeds of any such purchase are distributed is less than
ten percent of the aggregate Stated Principal Balance of the Mortgage Loans at
the Cut-off Date.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

         evidencing percentage interest in the distributions allocable to the
         Class C Certificates with respect to a Trust Fund consisting primarily
         of a pool of conforming one- to four- family fixed-rate first lien
         mortgage loans formed and sold by IMPAC SECURED ASSETS CORP.

         This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Impac Secured Assets
Corp., the Master Servicer, the Trustee referred to below or any of their
affiliates. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental agency or instrumentality or by Impac
Secured Assets Corp., the Master Servicer, the Trustee or any of their
affiliates. None of the Company, the Master Servicer or any of their affiliates
will have any obligation with respect to any certificate or other or obligation
secured by or payable from payments on the Certificates.

         This certifies that __________ is the registered owner of the
Percentage Interest evidenced by this Class C Certificate (obtained by dividing
the Original Class C Certificate by the Original Class Certificate Principal
Balance) in certain distributions with respect to a Trust consisting primarily
of the Mortgage Loans deposited by Impac Secured Assets Corp. (the "Company").
The Trust was created pursuant to a Pooling and Servicing Agreement dated as of
January 1, 2002 (the "Agreement") among the Company, Impac Funding Corporation,
as master servicer (the "Master Servicer"), and Bankers Trust Company of
California, N.A., as Trustee (the "Trustee"). To the extent not defined herein,
the capitalized terms used herein have the meanings assigned in the

                                      B-2-2

<PAGE>

Agreement. This Class C Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Class C Certificate by virtue of the acceptance hereof assents and by which
such Holder is bound.

         Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last Business Day of the month
immediately preceding the month of such Distribution Date (the "Record Date"),
from the Available Distribution Amount in an amount equal to the product of the
Percentage Interest evidenced by this Certificate and the amount (of interest
and principal, if any) required to be distributed to Holders of Class C
Certificates on such Distribution Date.

         Distributions on this Certificate will be made either by the Trustee or
by a Paying Agent appointed by the Trustee either in immediately available funds
(by wire transfer or otherwise) for the account of the Person entitled thereto
if such Person shall have so notified the Trustee or such Paying Agent at least
5 Business Days prior to the related Record Date, or by check mailed to the
address of the Person entitled thereto, as such name and address shall appear on
the Certificate Register.

         Notwithstanding the above, the final distribution on this Certificate
will be made after due notice of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose in the City and State of New York.

         This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

         The Certificates are limited in right of payment to certain collections
and recoveries respecting the Mortgage Loans, all as more specifically set forth
herein and in the Agreement. In the event Master Servicer funds are advanced
with respect to any Mortgage Loan, such advance is reimbursable to the Master
Servicer, to the extent provided in the Agreement, from related recoveries on
such Mortgage Loan or from other cash that would have been distributable to
Certificateholders.

         As provided in the Agreement, withdrawals from the Custodial Account
and/or the Certificate Account created for the benefit of Certificateholders may
be made by the Master Servicer from time to time for purposes other than
distributions to Certificateholders, such purposes including without limitation
reimbursement to the Trustee, the Company and the Master Servicer of advances
made, or certain expenses incurred, by either of them.

         No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is

                                      B-2-3

<PAGE>

exempt from the registration requirements under said Act and such laws. In the
event that a transfer is to be made in reliance upon an exemption from the Act
and such laws, in order to assure compliance with the act and such laws, the
Certificateholder desiring to effect such transfer and such Certificateholder's
prospective transferee shall each certify to the Trustee and the Company in
writing the facts surrounding the transfer. In the event that such a transfer is
not to be made pursuant to Rule 144A of the act, there shall be delivered to the
Trustee and the Company of an Opinion of Counsel that such transfer may be made
pursuant to an exemption from the Act, which Opinion of Counsel shall not be
obtained at the expense of the Trustee, the Master Servicer or the Company; or
there shall be delivered to the Trustee and the Company a transferor certificate
by the transferor and an investment letter shall be executed by the transferee.
The Holder hereof desiring to effect such transfer shall, and does hereby agree
to, indemnify the Trustee and the Company against any liability that may result
if the transfer is not so exempt or is not made in accordance with such federal
and state laws.

         No transfer of this Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any person using Plan Assets to acquire this Certificate shall be
made except in accordance with Section 5.02(d) of the Agreement.

         The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon the Certificate. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee, duly endorsed by, or accompanied
by an assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same Class and aggregate Percentage Interest will be issued to the
designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in Classes and in denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of authorized

                                      B-2-4

<PAGE>

denominations evidencing the same Class and aggregate Percentage Interest, as
requested by the Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Company, the Master Servicer, the Trustee and the Certificate
Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the
Master Servicer, the Trustee nor any such agent shall be affected by notice to
the contrary.

         This Certificate shall be governed by and construed in accordance with
the laws of the State of New York.

         The obligations created by the Agreement in respect of the Certificates
and the Trust Fund created thereby shall terminate upon the payment to
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the purchase by the Holder of at least 50.01% Percentage Interest in the
Class C Certificates (the "Majority Class C Certificateholder") from the Trust
Fund of all remaining Mortgage Loans and each REO Property in respect thereof
remaining in the Trust Fund, thereby effecting early retirement of the
Certificates and (ii) the final payment or other liquidation (or any Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust Fund (or
the disposition of all REO Property in respect, thereof). The Agreement permits,
but does not require, the Majority Class C Certificateholder to purchase at a
price determined as provided in the Agreement all remaining Mortgage Loans and
all REO Property; provided, that any such option may only be exercised if the
aggregate Stated Principal Balance of the Mortgage Loans as of the Distribution
Date upon which the proceeds of any such purchase are distributed is less than
ten percent of the aggregate Stated Principal Balance of the Mortgage Loans at
the Cut-off Date.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

         of a pool of one- to four-family fixed-rate first lien mortgage loans
         formed and sold by IMPAC SECURED ASSETS CORP.

         This Certificate is payable solely from the assets of the Trust Fund,
and does not represent an obligation of or interest in Impac Secured Assets
Corp., the Master Servicer, the Trustee referred to below or any of their
affiliates. Neither this Certificate nor the underlying Mortgage Loans are
guaranteed or insured by any governmental agency or instrumentality or by Impac
Secured Assets Corp., the Master Servicer, the Trustee or any of their

will have any obligation with respect to any certificate or other obligation

         This certifies that ________________ is the registered owner of the
Percentage Interest evidenced by this Certificate stated above in certain

<PAGE>

"Mortgage Loans"), formed and sold by Impac Secured Assets Corp. (hereinafter
called the "Company," which term includes any successor entity under the
Agreement referred to below). The Trust Fund was created pursuant to a Pooling
and Servicing Agreement dated as specified above (the "Agreement") among the
Company, the Master Servicer and Bankers Trust Company of California, N.A., as
trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth hereafter. To the extent not defined herein, the capitalized
terms used herein have the meanings assigned in the Agreement. This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

         This Certificate does not have a principal balance or pass-through rate
and will be entitled to distributions only to the Patent set forth in the
Agreement. In addition, any distribution of the proceeds of any remaining assets
of the Trust will be made only upon presentment and surrender of this
Certificate at the Corporate Trust Office or the office or agency maintained by
the Trustee in California.

         This Certificate is one of a duly authorized issue of Certificates
issued in several Classes designated as Mortgage Pass-Through Certificates of
the Series specified hereon (herein collectively called the "Certificates").

         As provided in the Agreement, withdrawals from the Custodial Account
and/or the Certificate Account created for the benefit of Certificateholders may
be made by the Master Servicer from time to time for purposes other than
distributions to Certificateholders, such purposes including without limitation
reimbursement to the Trustee, the Company and the Master Servicer of advances
made, or certain expenses incurred, by either of them.

         No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Company in writing the facts surrounding the
transfer. In the event that such a transfer is not to be made pursuant to Rule
144A of the Act, there shall be delivered to the Trustee and the Company of an
Opinion of Counsel that such transfer may be made pursuant to an exemption from
the Act, which Opinion of Counsel shall not be obtained at the expense of the
Trustee, the Master Servicer or the Company; or there shall be delivered to the
Trustee and the Company a transferor certificate by the transferor and an
investment letter shall be executed by the transferee. The Holder hereof
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee and the Company against any liability that may result if the transfer is
not so exempt or is not made in accordance with such federal and state laws.

         No transfer of this Certificate to a Plan subject to ERISA or Section
4975 of the Code, any Person acting, directly or indirectly, on behalf of any
such Plan or any person using Plan Assets to acquire this Certificate shall be
made except in accordance with Section 5.02(d) of the Agreement.

         Each Holder of this Certificate will be deemed to have agreed to be
bound by the restrictions of the Agreement, including but not limited to the
restrictions that (i) each person holding or acquiring any Ownership Interest in
this Certificate must be a Permitted Transferee, (ii) no Ownership Interest, in
this Certificate may be transferred without delivery to the Trustee of (a) a
transfer affidavit of the proposed transferee and (b) a transfer certificate of
the transferor, each of such documents to be in the form described in the
Agreement, (iii) each person holding or acquiring any Ownership Interest in this
Certificate must agree to require a transfer affidavit and to deliver a transfer
certificate to the Trustee as required pursuant to the Agreement, (iv) each
person holding or acquiring an Ownership Interest in this Certificate must agree
not to transfer an Ownership Interest in this Certificate if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee. Pursuant to the Agreement, the Trustee will
provide the Internal Revenue Service and any pertinent persons with the
information needed to compute the tax imposed under the applicable tax laws on
transfers of residual interests to disqualified organizations, if any person
other than a Permitted Transferee acquires an Ownership Interest on a Class R
Certificate in violation of the restrictions mentioned above.

         The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66-2/3% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate issued upon the
transfer hereof or in exchange herefor or in lieu hereof whether or not notation
of such consent is made upon the Certificate. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

         As provided in the Agreement and subject to certain limitations therein
set forth, the transfer of this Certificate is registrable in the Certificate
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies appointed by the Trustee, duly endorsed by, or accompanied
by an, assignment in the form below or other written instrument of transfer in
form satisfactory to the Trustee and the Certificate Registrar duly executed by
the Holder hereof or such Holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of authorized denominations evidencing
the same Class and aggregate Percentage Interest will be issued to the
designated transferee or transferees.

         The Certificates are issuable only as registered Certificates without
coupons in Classes and in denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of authorized denominations
evidencing the same Class and aggregate Percentage Interest, as requested by the
Holder surrendering the same.

         No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         The Company, the Master Servicer, the Trustee and the Certificate
Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name this Certificate is
registered as the owner hereof for all purposes, and neither the Company, the
Master Servicer, the Trustee nor any such agent shall be affected by notice to
the contrary.

         This Certificate shall be governed by and construed in accordance with
the laws of the State of New York.

         The obligations created by the Agreement in respect of the Certificates
and the Trust Fund created thereby shall terminate upon the payment to
Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the purchase by the Holder of at least 50.01 % Percentage Interest in the
Class C Certificates (the "Majority Class C Certificateholder") from the Trust
Fund of all remaining Mortgage Loans and each REO Property, in respect thereof
remaining in the Trust Fund, thereby effecting early retirement of the
Certificates and (ii) the final payment or other liquidation (or any Advance
with respect thereto) of the last Mortgage Loan remaining in the Trust Fund (or
the disposition of all REO Property in respect thereof). The Agreement permits,
but does not require, the Majority Class C Certificateholder to purchase at a
price determined as provided in the Agreement all remaining Mortgage Loans and
all REO Property; provided, that any such option may only be exercised if the
aggregate Stated Principal Balance of the Mortgage Loans as of the Distribution
Date upon which the proceeds of any such purchase are distributed is less than
ten percent of the aggregate Stated Principal Balance of the Mortgage Loans at
the Cut-off Date.

         Unless the certificate of authentication hereon has been executed by
the Trustee, by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

                           1. The Purchaser understands that (a) the

                  Certificates may be resold only if registered and qualified
                  pursuant to the provisions of the Act or any state securities
                  law, or if an exemption from such registration and
                  qualification is available, (d) the Pooling and Servicing
                  Agreement contains restrictions regarding the transfer of the
                  Certificates and (e) the Certificates will bear a legend to
                  the foregoing effect.

                                      G-1-1

<PAGE>

                           2. The Purchaser is acquiring the Certificates for
                  its own account for investment only and not with a view to or
                  for sale in connection with any distribution thereof in any
                  manner that would violate the Act or any applicable state
                  securities laws.

                           3. The Purchaser is (a) a substantial, sophisticated
                  institutional investor having such knowledge and experience in
                  financial and business matters, and, in particular, in such
                  matters related to securities similar to the Certificates,
                  such that it is capable of evaluating the merits and risks of
                  investment in the Certificates, (b) able to bear the economic
                  risks of such an investment and (c) an "accredited investor"
                  within the meaning of Rule 501 (a) promulgated pursuant to the
                  Act.

                           4. The Purchaser has been furnished with, and has had
                  an opportunity to review (a) [a copy of the Private Placement
                  Memorandum, dated January 31, 2002, relating to the
                  Certificates (b)] a copy of the Pooling and Servicing
                  Agreement and [(b)] [(c)] such other information concerning
                  the Certificates, the Mortgage Loans and the Company as has
                  been requested by the Purchaser from the Company or the Seller
                  and is relevant to the Purchaser's decision to purchase the
                  Certificates. The Purchaser has had any questions arising from
                  such review answered by the Company or the Seller to the
                  satisfaction of the Purchaser. [If the Purchaser did not
                  purchase the Certificates from the Seller in connection with
                  the initial distribution of the Certificates and was provided
                  with a copy of the Private Placement Memorandum (the
                  "Memorandum") relating to the original sale (the "Original
                  Sale") of the Certificates by the Company, the Purchaser
                  acknowledges that such Memorandum was provided to it by the
                  Seller, that the Memorandum was prepared by the Company solely
                  for use in connection with the Original Sale and the Company
                  did not participate in or facilitate in any way the purchase
                  of the Certificates by the Purchaser from the Seller, and the
                  Purchaser agrees that it will look solely to the Seller and
                  not to the Company with respect to any damage, liability,
                  claim or expense arising out of, resulting from or in
                  connection with (a) error or omission, or alleged error or
                  omission, contained in the Memorandum, or (b) any information,
                  development or event arising after the date of the
                  Memorandum.]

                           5. The Purchaser has not and will not nor has it
                  authorized or will it authorize any person to (a) offer,
                  pledge, sell, dispose of or otherwise transfer any
                  Certificate, any interest in any Certificate or any other
                  similar security to any person in any manner, (b) solicit any
                  offer to buy or to accept a pledge, disposition of other
                  transfer of any Certificate, any interest in any Certificate
                  or any other similar security from any person in any manner,
                  (c) otherwise approach or negotiate with respect to any
                  Certificate, any interest in any Certificate or any other
                  similar security with any person in any manner, (d) make any
                  general solicitation by means of general advertising or in any
                  other manner or (e) take any other action, that (as to any of
                  (a) through (e) above) would constitute a distribution of any
                  Certificate under the Act,

                                      G-1-2

                  that would render the disposition of any Certificate a
                  violation of Section 5 of the Act or any state securities law,
                  or that would require registration or qualification pursuant
                  thereto. The Purchaser will not sell or otherwise transfer any
                  of the Certificates, except in compliance with the provisions
                  of the Pooling and Servicing Agreement.

                                              Very truly yours,

<PAGE>

                           d. Neither the Buyer nor anyone acting on its behalf
                  has offered, transferred, pledged, sold or otherwise disposed
                  of the Rule 144A Securities, any interest in the Rule 144A
                  Securities or any other similar security to, or solicited any

                  other similar security with, any person in any manner, or made
                  any general solicitation by means of general advertising or in
                  any other manner, or taken any other action, that would
                  constitute a distribution of the Rule 144A Securities under
                  the 1933 Act or that would render the disposition of the Rule
                  144A Securities a violation of Section 5 of the 1933 Act or

                  institutional buyer to whom notice is given that the resale,
                  pledge or transfer is being made in reliance on Rule 144A, or
                  (ii) pursuant to another exemption from registration under the
                  1933 Act.

                  3. The Buyer warrants and represents to, and covenants with,
the Transferor, the Servicer and the Company that either (1) the Buyer is not an
employee benefit plan within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") ("Plan"), or a plan
within the meaning of Section 4975(e)(1) of the Internal Revenue Code of 1986

144A, the Buyer will only purchase for the account of a third party that at the
time is a "qualified institutional buyer" within the meaning of Rule 144A. In
addition, the Buyer agrees that the Buyer will not purchase securities for a
third party unless the Buyer has obtained a current representation letter from
such third party or taken other appropriate steps contemplated by Rule 144A to
conclude that such third party independently meets the definition of "qualified
institutional buyer" set forth in Rule 144A.

         7. The Buyer will notify each of the parties to which this
certification is made of any changes in the information and conclusions herein.
Until such notice is given, the Buyer's purchase of Rule 144A Securities will
constitute a reaffirmation of this certification as of the date of such
purchase.

                           Mortgage Pass-Through Certificates
                           Series 2002-1, Class R
                           ----------------------

Ladies and Gentlemen:

                  This letter is delivered to you in connection with the sale by
________________________ (the "Seller") to _____________________________________
(the "Purchaser") of a ____% Percentage Interest in the Mortgage Pass-Through
Certificates, Series 2002-1, Class R (the "Certificates"), issued pursuant to
Section 5.02 of the Pooling and Servicing Agreement (the "Pooling and Servicing
Agreement"), dated as of January 1, 2002, among Impac Secured Assets Corp., as
company (the "Company"), Impac Funding Corporation, as master servicer and
Bankers Trust Company of California, N.A., as trustee (the "Trustee"). All terms
used herein and not otherwise defined shall have the meaning set forth in the
Pooling and Servicing Agreement. The Seller hereby certifies, represents and
warrants to, and covenants with, the Company and the Trustee that:

                  1. No purpose of the Seller relating to the sale of the
Certificates by the Seller to the Purchaser is or will be to impede the
assessment or collection of any tax.

                  2. The Seller understands that the Purchaser has delivered to
the Trustee and the Master Servicer a transfer affidavit and agreement in the
form attached to the Pooling and Servicing Agreement as Exhibit G-5. The Seller
does not know or believe that any representation contained therein is false.

                                      G-4-1

<PAGE>

                  3. The Seller has at the time of the transfer conducted a
reasonable investigation of the financial condition of the Purchaser as
contemplated by Treasury Regulations Section 1.860E- 1(c)(4)(i) and, as a result
of that investigation, the Seller has determined that the Purchaser has
historically paid its debts as they have become due and has found no significant
evidence to indicate that the Purchaser will not continue to pay its debts as
they become due in the future. The Seller understands that the transfer of the
Certificates may not be respected for United States income tax purposes (and the
Seller may continue to be liable for United States income taxes associated
therewith) unless the Seller has conducted such an investigation.

                  4. The Seller has no actual knowledge that the proposed
Transferee is a Disqualified Organization, an agent of a Disqualified
Organization or a Non-United States Person.

                                           Very truly yours,

                                           ___________________________________

                           :ss.:
COUNTY OF                           )

         ___________________, being first duly sworn, deposes, represents and
warrants:

         1. That he/she is [Title of Officer] of [Name of Owner], a [savings
institution] [corporation] duly organized and existing under the laws of [the
State of __________] [the United States], (the "Owner"), (record or beneficial
owner of the Class R Certificates (the "Class R Certificates") on behalf of
which he/she makes this affidavit and agreement). This Class R Certificates were
issued pursuant to the Pooling and Servicing Agreement (the "Pooling and
Servicing Agreement") dated as of January 1, 2002 among Impac Secured Assets
Corp., as company, Impac Funding Corporation, as master servicer (the "Master
Servicer"), and Bankers Trust Company of California, N.A., as trustee (the
"Trustee").

         2. That the Owner (i) is not and will not be a "disqualified
organization" as of _____________ [date of transfer] within the meaning of
Section 860E(e)(5) of the Internal Revenue Code of 1986, as amended (the
"Code"), (ii) will endeavor to remain other than a disqualified organization for
so long as it retains its ownership interest in the Class R Certificates, and
(iii) is acquiring the Class R Certificates for its own account or for the
account of another Owner from which it has received an affidavit and agreement
in substantially the same form as this affidavit and agreement. (For this
purpose, a "disqualified organization" means the United States, any state or
political subdivision thereof, any agency or instrumentality of any of the
foregoing (other than an instrumentality all of the activities of which are
subject to tax and, except for Freddie Mac, a majority of whose board of
directors is not selected by any such governmental entity) or any foreign
government, international organization or any agency or instrumentality of such
foreign government or organization, any rural electric or telephone cooperative,
or any organization (other than certain farmers' cooperatives) that is generally
exempt from federal income tax unless such organization is subject to the tax on
unrelated business taxable income).

         3. That the Owner is aware (i) of the tax that would be imposed on
transfers of Class R Certificates to disqualified organizations under the Code,
that applies to all transfers of Class R Certificates after March 31, 1988; (ii)

agent (which person includes a broker, nominee or middleman) for a disqualified
organization, on the agent; (iii) that the person otherwise liable for the tax
shall be relieved of liability for the tax if the transferee furnishes to such
person an affidavit that the transferee is not a disqualified organization and,
at the time of transfer, such person does not have actual knowledge

                                      G-5-1

<PAGE>

that the affidavit is false; and (iv) that the Class R Certificates may be
"noneconomic residual interests" within the meaning of Treasury regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

         4. That the Owner is aware of the tax imposed on a "pass-through
entity" holding Class R Certificates if at any time during the taxable year of
the pass-through entity a disqualified organization is the record holder of an
interest in such entity. (For this purpose, a "pass through entity" includes a
regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

         5. That the Owner is aware that the Trustee will not register the
transfer of any Class R Certificates unless the transferee, or the transferee's
agent, delivers to it an affidavit and agreement, among other things, in
substantially the same form as this affidavit and agreement. The Owner expressly
agrees that it will not consummate any such transfer if it knows or believes
that any of the representations contained in such affidavit and agreement are
false.

         6. That the Owner has reviewed the restrictions set forth on the face
of the Class R Certificates and the provisions of Section 5.02(f) of the Pooling
and Servicing Agreement under which the Class R Certificates were issued (in
particular, clause (iii)(A) and (iii)(B) of Section 5.02(f) which authorize the
Trustee to deliver payments to a person other than the Owner and negotiate a
mandatory sale by the Trustee in the event the Owner holds such Certificates in
violation of Section 5.02(f)). The Owner expressly agrees to be bound by and to
comply with such restrictions and provisions.

         7. That the Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class R Certificates will only be
owned, directly or indirectly, by an Owner that is not a disqualified
organization.

         8. The Owner's Taxpayer Identification Number is _____________________.

         9. This affidavit and agreement relates only to the Class R
Certificates held by the owner and not to any other holder of the Class R
Certificates. The Owner understands that the liabilities described herein relate
only to the Class R Certificates.

         10. That no purpose of the Owner relating to the transfer of any of the
Class R Certificates by the Owner is or will be to impede the assessment or
collection of any tax.

         11. That the Owner has no present knowledge or expectation that it will
be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding. In this regard, the Owner hereby represents to
and for the benefit of the person from whom it acquired the

                                      G-5-2

<PAGE>

Class R Certificate that the Owner intends to pay taxes associated with holding
such Class R Certificate as they become due, fully understanding that it may
incur tax liabilities in excess of any cash flows generated by the Class R
Certificate.

         12. That the Owner has no present knowledge or expectation that it will
become insolvent or subject to a bankruptcy proceeding for so long as any of the
Class R Certificates remain outstanding.

         13. The Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof, provided that
with respect to any partnership or other entity treated as a partnership for
United States federal income tax purposes, 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 or trust whose
income from sources without the United States is includible in gross income for
United States federal income tax purposes regardless of its connection with the
conduct of a trade or business within the United States.

         14. (a) The Certificates (i) are not being acquired by, and will not be
transferred to, any employee benefit plan within the meaning of section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA") or
other retirement arrangement, including individual retirement accounts and
annuities, Keogh plans and bank collective investment funds and insurance
company general or separate accounts in which such plans, accounts or
arrangements are invested, that is subject to Section 406 of ERISA or Section
4975 of the Internal Revenue Code of 1986 (the "Code") (any of the foregoing, a
"Plan"), (ii) are not being acquired with "plan assets" of a Plan within the
meaning of the Department of Labor ("DOL") regulation, 29 C.F.R. ss. 2510.3-101
or otherwise under ERISA, and (iii) will not be transferred to any entity that
is deemed to be investing in plan assets within the meaning of the DOL
regulation, 29 C.F.R. ss. 2510.3-101 or otherwise under ERISA; or

                  (b) The Owner will provide the Trustee, the Company and the
Master Servicer with an opinion of counsel acceptable to and in form and
substance satisfactory to the Trustee, the Company and the Master Servicer to
the effect that the purchase of Certificates is permissible under applicable
law, will not constitute or result in any non-exempt prohibited transaction
under ERISA or Section 4975 of the Code and will not subject the Trustee, the
Company or the Master Servicer to any obligation or liability (including
obligations or liabilities under ERISA or Section 4975 of the Code) in addition
to those undertaken in the Pooling and Servicing Agreement.

         In addition, the Owner hereby certifies, represents and warrants to,
and covenants with, the Company, the Trustee and the Master Servicer that the
Owner will not transfer such Certificates to any Plan or person unless either
such Plan or person meets the requirements set forth in either (a) or (b) above.
