         THIS POOLING AND SERVICING AGREEMENT, dated as of December 1, 2000, is
hereby executed by and among STRUCTURED ASSET MORTGAGE INVESTMENTS INC., a
Delaware corporation, as seller (the "Seller"), WASHINGTON MUTUAL BANK, FA
("Washington Mutual"), in its capacity as mortgage loan seller (the "Mortgage
Loan Seller") and in its capacity as master servicer (the "Master Servicer"),
and BANKERS TRUST COMPANY OF CALIFORNIA, N.A., a national banking association,
as trustee (the "Trustee"). Capitalized terms used in this Agreement and not
otherwise defined herein will have the meanings assigned to them in Article I
below.

                              PRELIMINARY STATEMENT

         The Seller has acquired the Mortgage Loans from the Mortgage Loan
Seller on the Closing Date pursuant to the Mortgage Loan Purchase Agreement and
is the owner of the Mortgage Loans and the other property being conveyed by it
to the Trustee for inclusion in the Trust Fund. The Seller has duly authorized
the execution and delivery of this Agreement to provide for the conveyance to
the Trustee of the Mortgage Loans and the other property constituting the Trust
Fund in exchange for the Certificates.

         All covenants and agreements made by the Seller, the Mortgage Loan
Seller, the Master Servicer and the Trustee herein with respect to the Mortgage
Loans and the other property constituting the Trust Fund are for the benefit and
security of the Certificateholders. The Seller, the Mortgage Loan Seller and the
Master Servicer are entering into this Agreement, and the Trustee is accepting
the trusts created hereby and thereby, for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged.

         The Trustee on behalf of the Trust shall make an election for the
assets constituting the Trust Fund to be treated for federal income tax purposes
as a REMIC. On the Closing Date, all the Classes of Certificates (other than the
Class R Certificates) will be designated "regular interests" in the REMIC and
the Class R Certificates will be designated the "residual interest" in the
REMIC.

         As of the Cut-off Date, the Mortgage Loans had an aggregate Scheduled
Principal Balance of $1,996,677,711.

         The parties hereto intend to effect an absolute sale and assignment of
the Mortgage Loans to the Trustee for the benefit of Certificateholders under
the Mortgage Loan Purchase Agreement and this Agreement. However, the Mortgage
Loan Seller and the Seller will hereunder absolutely assign, and as a
precautionary matter grant a security interest in and to, its rights, if any, in
the Trust Fund and the Mortgage Loans to the Trustee on behalf of
Certificateholders to ensure that the interest of the Certificateholders
hereunder in the Mortgage Loans is fully protected.

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

         In consideration of the mutual agreements herein contained, the Seller,

Mortgage Loans and the interest portion of any Realized Losses on the Mortgage
Loans allocated thereto 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. Such Net Interest

         SECTION 2.04      REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
                           MORTGAGE LOAN SELLER WITH RESPECT TO THE MORTGAGE
                           LOANS.
                           -------------------------------------------------

         (a) The Mortgage Loan Seller hereby represents and warrants to, and
covenants with, the Seller and the Trustee for the benefit of the
Certificateholders that, as to each Mortgage Loan, as of the Cut-off Date or
such other date specifically set forth herein, and with respect to
representation (i) listed below, as of the Closing Date:

                  (i) The information set forth in the Mortgage Loan Schedule is
         complete, true and correct.

                  (ii) None of the Mortgage Loans (by Scheduled Principal
         Balance) are more than 30 days delinquent; Washington Mutual has not
         advanced funds to, or induced, solicited or knowingly received any
         advance of funds from a party other than the owner of the Mortgaged
         Property subject to the Mortgage, directly or indirectly, for the
         payment of any amount required by the Mortgage Loan.

                  (iii) There are no delinquent taxes, ground rents, water
         charges, sewer rents, assessments, insurance premiums, leasehold
         payments, including assessments payable in future installments or other
         outstanding charges affecting the related Mortgaged Property.

                  (iv) The terms of the Mortgage Note and the Mortgage have not
         been impaired, waived, altered or modified in any respect, except by
         written instruments which have been recorded, if necessary to protect
         the interests of the Trustee, and which are included in the Trustee
         Mortgage File, the substance of which waiver, alteration or
         modification has been approved by the primary mortgage guaranty
         insurer, if any, and by the title insurer, to the extent required by
         the related policy and is reflected on the Mortgage Loan Schedule. No
         instrument of waiver, alteration or modification has been executed, and
         no Mortgagor has been released, in whole or in part, except in
         connection with an assumption agreement approved by the primary
         mortgage insurer, if any, and title insurer, to the extent required by
         the policy, and which assumption agreement is part of the Mortgage
         File.

                  (v) The Mortgage Note and the Mortgage are not subject to any
         right of rescission, set-off, counterclaim or defense, including the
         defense of usury, nor will the operation of any of the terms of the
         Mortgage Note and Mortgage, or the exercise of any right thereunder,
         render the Mortgage unenforceable, in whole or in part, or subject to
         any right of rescission, set-off, counterclaim or defense, including
         the defense of usury and no such right of rescission, set-off,
         counterclaim or defense has been asserted with respect thereto.

                  (vi) All buildings upon the Mortgaged Property are insured by
         a generally acceptable insurer against loss by fire, hazards of
         extended coverage and such other hazards as are customary in the area
         where the Mortgaged Property is located. All such insurance policies
         contain a standard mortgagee clause naming the Master Servicer, its
         successors and

                                       31

<PAGE>

         assigns as mortgagee and all premiums due thereon have been paid. If
         upon origination of the Mortgage Loan, the Mortgaged Property was in an
         area identified in the Federal Register by the Federal Emergency
         Management Agency as having special flood hazards (and such flood
         insurance has been made available) a flood insurance policy meeting the
         requirements of the current guidelines of the Federal Insurance
         Administration is in effect which policy conforms to the requirements
         of Fannie Mae or Freddie Mac. The Mortgage obligates the Mortgagor
         thereunder to maintain all such insurance at Mortgagor's cost and
         expense, and on the Mortgagor's failure to do so, authorizes the holder
         of the Mortgage to maintain such insurance at Mortgagor's cost and
         expense and to seek reimbursement therefor from the Mortgagor.

                  (vii) Any and all requirements of any federal, state or local
         law including, without limitation, environmental, usury, truth in
         lending, real estate settlement procedures, consumer credit protection,
         equal credit opportunity or disclosure laws applicable to the Mortgage
         Loan and the related Mortgaged Property have been complied with.

                  (viii) The Mortgage has not been satisfied, canceled or
         subordinated, or rescinded, in whole or in part, and the Mortgaged
         Property has not been released from the lien of the Mortgage, in whole
         or in part, nor has any instrument been executed that would effect any
         such release, cancellation, subordination or rescission.

                  (ix) The Mortgage is a valid, existing and enforceable first
         lien on the Mortgaged Property, including all improvements on the
         Mortgaged Property subject only to (A) the lien of current real
         property taxes and assessments not yet due and payable, (B) covenants,
         conditions and restrictions, rights of way, easements and other matters
         of the public record as of the date of recording being acceptable to
         mortgage lending institutions generally and specifically referred to in
         lender's title insurance policy delivered to the originator of the
         Mortgage Loan and which do not adversely affect the Appraised Value of
         the Mortgaged Property, and (C) other matters to which like properties
         are commonly subject which do not materially interfere with the
         benefits of the security intended to be provided by the Mortgage or the
         use, enjoyment, value or marketability of the related Mortgaged
         Property. Any security agreement, chattel mortgage or equivalent
         document related to and delivered in connection with the Mortgage
         establishes and creates a valid, existing and enforceable first lien
         and first priority security interest on the property described therein
         and the Mortgage Loan Seller has full right to sell and assign the same
         to the Seller.

                  (x) The Mortgage Note and the related Mortgage are genuine and
         each is the legal, valid and binding obligation of the maker thereof,
         enforceable in accordance with its terms, except as the enforceability
         thereof may be limited by bankruptcy, insolvency, or reorganization.

                  (xi) All parties to the Mortgage Note and the Mortgage had
         legal capacity to enter into the Mortgage Loan and to execute and
         deliver the Mortgage Note and the Mortgage, and the Mortgage Note and
         the Mortgage have been duly and properly executed by such parties.

                                       32

<PAGE>

                  (xii) The proceeds of the Mortgage Loan have been fully
         disbursed and there is no requirement for future advances thereunder
         and any and all requirements as to completion of any on-site or
         off-site improvement and as to disbursements of any escrow funds
         therefor have been complied with. All costs, fees and expenses incurred
         in making or closing the Mortgage Loan and the recording of the
         Mortgage were paid, and the Mortgagor is not entitled to any refund of
         any amounts paid or due under the Mortgage Note or Mortgage.

                  (xiii) As of the Closing Date, the Mortgage Note and the
         Mortgage are not assigned or pledged, and immediately prior to the sale
         of the Mortgage Loan to the Seller, the Mortgage Loan Seller was the
         sole owner of record and holder thereof and with full right to transfer
         and sell the Mortgage Loan to the Seller free and clear of any
         encumbrance, equity, lien, pledge, charge, claim or security interest
         and with full right and authority subject to no interest or
         participation of, or agreement with, any other party, to sell and
         assign each Mortgage Loan pursuant to the Mortgage Loan Purchase
         Agreement.

                  (xiv) The Mortgage Loan Seller or, if the Mortgage Loan was
         not originated by the Mortgage Loan Seller, the originator is or was
         (or, during the period in which they held and disposed of such
         interest, were) (A) in compliance with any and all applicable licensing
         requirements of the laws of the state wherein the Mortgaged Property is
         located, and (B) either (i) organized under the laws of such state, or
         (ii) qualified to do business in such state, or (iii) federal savings
         and loan associations or national banks having principal offices in
         such state, or (iv) not doing business in such state.

                  (xv) The Mortgage Loan is covered by an ALTA lender's title
         insurance policy acceptable to Fannie Mae or Freddie Mac, issued by a
         title insurer acceptable to Fannie Mae or Freddie Mac and qualified to
         do business in the jurisdiction where the Mortgaged Property is
         located, insuring (subject to the exceptions contained in (ix)(A)
         through (C) above) the Mortgage Loan Seller, its successors and assigns
         as to the first priority lien of the Mortgage in the original principal
         amount of the Mortgage Loan. The original title policy (or a copy
         thereof sufficient to entitle the insured to make a claim thereunder)
         and all riders thereto are in the Master Servicer Mortgage File or
         otherwise maintained by the Master Servicer. Additionally, such
         lender's title insurance policy affirmatively insures ingress and
         egress, and against encroachments by or upon the Mortgaged Property or
         any interest therein. The Mortgage Loan Seller is the sole insured of
         such lender's title insurance policy, and such lender's title insurance
         policy is in full force and effect and will be in full force and effect
         upon the consummation of the transactions contemplated by this
         Agreement. No claims have been made under such lender's title insurance
         policy, and no prior holder of the related Mortgage, including the
         Mortgage Loan Seller, has done, by act or omission, anything which
         would impair the coverage of such lender's title insurance policy.

                  (xvi) Except for Mortgage Loans which are delinquent in
         payment not more than 30 days, there is no default, breach, violation
         or event of acceleration existing under the Mortgage or the Mortgage
         Note and no event which, with the passage of time or with notice and
         the expiration of any grace or cure period, would constitute a default,
         breach, violation or event of acceleration, and the Mortgage Loan
         Seller has not waived any default, breach, violation or event of
         acceleration.

                                       33

<PAGE>

                  (xvii) There are no mechanics' or similar liens or claims
         which have been filed for work, labor or material (and no rights are
         outstanding that under law could give rise to such lien) affecting the
         related Mortgaged Property which are or may be liens prior to, or equal
         or on parity with, the lien of the related Mortgage.

                  (xviii) All improvements which were considered in determining
         the Appraised Value of the related Mortgaged Property lay wholly within
         the boundaries and building restriction lines of the Mortgaged
         Property, and no improvements on adjoining properties encroach upon the
         Mortgaged Property.

                  (xix) The Mortgage Loan was originated by the Mortgage Loan
         Seller. Principal payments on the Mortgage Loan commenced no more than
         sixty-two days after funds were disbursed in connection with the
         Mortgage Loan. Each Mortgage Note has a Mortgage Rate that is
         adjustable, based on One-Month U.S. Treasury, in the following manner:
         Monthly Payments are due on the Due Date specified in the Mortgage Loan
         Schedule. Following the first interest rate adjustment date, the
         Mortgage Rate is subject to adjustment monthly on each interest rate
         adjustment date to a new Mortgage Rate (rounded as provided in the
         related Mortgage Note) equal to the Index (determined as of the date
         specified in the related Mortgage Note) plus the Gross Margin as
         specified in the Mortgage Loan Schedule, subject to a maximum lifetime
         interest rate as specified in the Mortgage Loan Schedule. The amount of
         each Monthly Payment is subject to adjustment on the anniversary of the
         first Due Date and annually on the same date thereafter, subject to the
         conditions that (i) the amount of a Monthly Payment will not increase
         or decrease by an amount that is more or less than 7.5% of the current
         Monthly Payment, (ii) on the fifth anniversary of the first Due Date
         and on the same day every five years thereafter, the Monthly Payment
         will be adjusted, without regard to the limitation in clause (i), to
         fully amortize the then unpaid principal balance over the remaining
         term to maturity and (iii) in the event that, as a result of Deferred
         Interest, the unpaid principal balance at any time would exceed the
         Negative Amortization Limit, the Monthly Payment will be adjusted at
         such time, without regard to the limitation in clause (i), to fully
         amortize the then unpaid principal balance over the remaining term to
         maturity. Any Deferred Interest will be added to the unpaid principal
         balance of the Mortgage Note on each Due Date, unless the Mortgagor (to
         the extent permitted in the Mortgage Note) elects to increase the
         amount of the Monthly Payment to include the amount of Deferred
         Interest or make a payment of the amount of Deferred Interest.

                  (xx) The origination practices used by the Mortgage Loan
         Seller and the collection practices used by the Master Servicer with
         respect to each Mortgage Note and Mortgage have been in all respects
         legal, proper, prudent and customary in the mortgage origination and
         servicing business. With respect to escrow deposits and escrow
         payments, if any, all such payments are in the possession of, or under
         the control of, the Master Servicer and there exist no deficiencies in
         connection therewith for which customary arrangements for repayment
         thereof have not been made.

                  (xxi) The Mortgaged Property is free of material damage and
         waste and there is no proceeding pending for the total or partial
         condemnation thereof.

                                       34

<PAGE>

                  (xxii) The Mortgage contains customary and enforceable
         provisions such as to render the rights and remedies of the holder
         thereof adequate for the realization against the Mortgaged Property of
         the benefits of the security provided thereby, including, (A) in the
         case of a Mortgage designated as a deed of trust, by trustee's sale,
         and (B) otherwise by judicial foreclosure. There is no other exemption
         available to the Mortgagor which would interfere with the right to sell
         the Mortgaged Property at a trustee's sale or the right to foreclose
         the Mortgage. The Mortgagor has not notified the Master Servicer and
         the Master Servicer has no knowledge of any relief requested or allowed
         to the Mortgagor under the Relief Act.

                  (xxiii) The Mortgage Loan was underwritten generally in
         accordance with the Mortgage Loan Seller's underwriting standards in
         effect at the time the Mortgage Loan was originated.

                  (xxiv) The Mortgage Note is not secured by any collateral
         except the lien of the corresponding Mortgage and the security interest
         of any applicable security agreement or chattel mortgage referred to in
         (ix) above.

                  (xxv) The Master Servicer Mortgage File contains an appraisal
         of the related Mortgaged Property signed prior to the approval of the
         Mortgage Loan application by a qualified appraiser, duly appointed by
         the originator of the Mortgage Loan, who had no interest, direct or
         indirect in the Mortgaged Property or in any loan made on the security
         thereof, and whose compensation is not affected by the approval or
         disapproval of the Mortgage Loan.

                  (xxvi) In the event the Mortgage constitutes a deed of trust,
         a trustee, duly qualified under applicable law to serve as such, has
         been properly designated and currently so serves and is named in the
         Mortgage, and no fees or expenses are or will become payable by the
         Seller to the trustee under the deed of trust, except, in connection
         with a trustee's sale after default by the Mortgagor.

                  (xxvii) No Mortgage Loan (A) contains provisions pursuant to
         which Monthly Payments are paid or partially paid with funds deposited
         in any separate account established by the Mortgage Loan Seller, the
         Mortgagor, or anyone on behalf of the Mortgagor or paid by any source
         other than the Mortgagor or (B) contains any provision permitting a
         temporary "buydown" of the related Mortgage Rate. No Mortgage Loan was
         a graduated payment mortgage loan as of the date of its origination. No
         Mortgage Loan has a shared appreciation or other contingent interest
         feature.

                  (xxviii) The Mortgage Loan Seller has no knowledge of any
         circumstances or condition existing on the Cut-off Date with respect to
         the Mortgage, the Mortgaged Property, the Mortgagor or the Mortgagor's
         credit standing that as of the Cut-off Date causes the Mortgage Loan to
         be an unacceptable investment, causes the Mortgage Loan to become
         delinquent, or adversely affects the value of the Mortgage Loan.

                  (xxix) Each such Mortgage Loan with a Loan-to-Value Ratio at
         origination in excess of 80% is and will be subject to a Primary
         Mortgage Insurance Policy, issued by a Fannie Mae or Freddie Mac
         approved insurer, which provided private mortgage insurance in an
         amount meeting Fannie Mae and Freddie Mac requirements. All provisions
         of such Primary Mortgage Insurance Policy have been and are being
         complied with, such policy is in full force and effect, and all
         premiums due thereunder have been paid. Any Mortgage subject to any
         such Primary Mortgage Insurance Policy obligates the Mortgagor
         thereunder to maintain such insurance and to pay all premiums and
         charges in connection therewith.

                  (xxx) The Mortgaged Property is lawfully occupied under
         applicable law. All inspections, licenses and certificates required to
         be made or issued with respect to all occupied portions of the related
         Mortgaged Property and, with respect to the use and occupancy of the
         same, including but not limited to certificates of occupancy, had been
         made or obtained from the appropriate authorities.

                  (xxxi) No defense against coverage under any private mortgage
         insurance (including, without limitation, any exclusions, denials or
         defenses which would limit or reduce the availability of the timely
         payment of the full amount of the loss otherwise due thereunder to the
         insured) exists arising out of actions, representations, errors,
         omissions, negligence, or fraud of the Mortgage Loan Seller, and the
         Mortgage Loan Seller is not aware of any fact that could reasonably
         lead the Mortgage Loan Seller to believe that any such defense exists
         arising out of the actions, representations, errors, omissions,
         negligence or fraud of the related Mortgagor or any party involved in
         the application for such coverage.

                  (xxxii) The Assignment is in recordable form, is acceptable
         for recording under the laws of the jurisdiction in which the Mortgaged
         Property is located and includes all applicable recording information,
         except where the related original Mortgage has been delivered for
         recording to the appropriate public recording office but has not yet
         been returned to the Mortgage Loan Seller.

                  (xxxiii) Any advances made to the Mortgagor prior to the
         Cut-off Date have been consolidated with the outstanding principal
         amount secured by the Mortgage, and the secured principal amount, as
         consolidated, bears a single interest rate and single repayment term.
         The lien of the Mortgage securing the consolidated principal amount is
         expressly insured as having first lien priority by a title insurance
         policy, an endorsement to the policy insuring the mortgagee's
         consolidated interest or by other title evidence acceptable to Fannie
         Mae or Freddie Mac. The consolidated principal amount does not exceed
         the original principal amount of the Mortgage Loan.

                  (xxxiv) If the Mortgaged Property is a condominium unit or a
         planned unit development (other than a de minimis planned unit
         development) such condominium or planned unit development project meets
         the Mortgage Loan Seller's eligibility requirements.

                  (xxxv) Each Mortgage Loan is a "qualified mortgage" for
         purposes of the REMIC Provisions.

                                       36

<PAGE>

                  (xxxvi) No fraud was committed by the originator of the
         Mortgage Loan and the Mortgage Loan Seller is not aware of any fact
         that would reasonably lead the Mortgage Loan Seller to believe that any
         Mortgagor had committed fraud in connection with the origination of
         such Mortgage Loan.

                  (xxxvii) Each Mortgage Loan identified on the Mortgage Loan
         Schedule as being covered by the PMI Policy is covered by the PMI
         Policy.

         (b) Upon the discovery by the Seller, the Mortgage Loan Seller, the
Master Servicer or the Trustee (or upon notice thereof in writing from a
Certificateholder) of a breach or breaches of any of the representations and
warranties of the Mortgage Loan Seller made in Section 2.04(a) in respect of any
Mortgage Loan, or any breach of a representation or warranty of the Mortgage
Loan Seller or Master Servicer set forth in Section 2.03 or any breach of
representation or warranty of the Mortgage Loan Seller in Section 2 of the
Mortgage Loan Purchase Agreement, which breach or breaches, individually or in
the aggregate, materially and adversely affect the interests of the
Certificateholders, the party discovering such breach shall give prompt written
notice to the other parties. The Trustee shall promptly notify the Mortgage Loan
Seller and Master Servicer of such breach of which a Responsible Officer has
actual knowledge or receives written notice and request that the Mortgage Loan
Seller or Master Servicer, as the case may be, cure such breach within 60 days
(or if such breach is not capable of being cured within 60 days and provided the
Mortgage Loan Seller or the Master Servicer, as the case may be is diligently
pursuing the cure thereof, within 120 days) from the date of such notice, and if
the Mortgage Loan Seller or Master Servicer does not cure such breach in all
material respects, the Mortgage Loan Seller or Master Servicer, as the case may
be, shall either (i) substitute a Replacement Mortgage Loan or Loans for the
related Mortgage Loan, which substitution must be made as specified in this
Section or (ii) purchase such Mortgage Loan held for the benefit of the
Certificateholders from the Trustee at the Purchase Price therefor.

         The Mortgage Loan Seller or Master Servicer shall not have any right to
substitute a Replacement Mortgage Loan or Loans for the affected Mortgage Loan
more than two years after the Closing Date if the related Mortgage Loan is a
"defective obligation" within the meaning of Section 860G(a)(4)(B)(ii) of the
Code, and any substitution must be accompanied by an Officers' Certificate
delivered to the Trustee, certifying that such Replacement Mortgage Loan
conforms to the requirements of this Agreement, and by an Opinion of Counsel to
the effect that such substitution will not cause the Trust Fund to fail to
qualify as a REMIC and will not result in a prohibited transaction tax, which
Opinion of Counsel shall be paid for by the Mortgage Loan Seller or Master
Servicer, as the case may be. Notwithstanding the foregoing, if any such breach
would cause a Mortgage Loan to be other than a "qualified mortgage loan" as
described in Section 860G(a)(3) of the Code, any substitution or purchase shall
occur within 90 days of the discovery of the breach.

         As to any Replacement Mortgage Loan or Loans, the Mortgage Loan Seller
or Master Servicer shall deliver to the Trustee or its agent for such
Replacement Mortgage Loan or Loans, the Mortgage Note, the Mortgage, and such
other documents and agreements as are required by Section 2.01(b), with the
Mortgage Note (i) endorsed in blank by facsimile signature if no Downgrade Event
has occurred or (ii) if a Downgrade Event has occurred, endorsed by facsimile
signature to the Trustee for the benefit of the Holders of the Washington Mutual
Mortgage Loan Trust Mortgage Pass-Through Certificates, Series 2000-3 (which
endorsement, in either case, may be in the form of

                                       37

<PAGE>

a note allonge). As to any Replacement Mortgage Loan or Loans, the Mortgage Loan
Seller or Master Servicer shall deliver to the Trustee the related Assignment
(i) in blank in recordable form or (ii) if a Downgrade Event has occurred,
assigned to the Trustee for the benefit of the Holders of the Washington Mutual
Mortgage Loan Trust Mortgage Pass-Through Certificates, Series 2000-3. No
substitution will be made in any calendar month after the Determination Date for
such month. Monthly Payments due with respect to Replacement Mortgage Loans in
the month of substitution shall not be part of the Trust Fund and will be
remitted by the Master Servicer to the Mortgage Loan Seller on the next
succeeding Distribution Date. For the month of substitution, distributions to
Certificateholders will include the Monthly Payment due on such Deleted Mortgage
Loan for such month and thereafter the Mortgage Loan Seller or Master Servicer,
as the case may be, shall be entitled to retain all amounts received in respect
of such Deleted Mortgage Loan.

         Upon such substitution, the Master Servicer shall amend or cause to be
amended the Mortgage Loan Schedule to reflect the removal of such Deleted
Mortgage Loan and the substitution of the Replacement Mortgage Loan or Loans and
shall deliver such amended Mortgage Loan Schedule to the Seller, the Mortgage
Loan Seller and the Trustee. Upon such substitution, the Replacement Mortgage
Loan or Loans shall be subject to the terms of this Agreement in all respects
and the Mortgage Loan Seller shall be deemed to have made, as of the date of
substitution, with respect to the Replacement Mortgage Loan or Loans, the
representations and warranties pertaining to the Mortgage Loans contained in
Section 2.04(a) hereof. Upon receipt of the Trustee Mortgage File pertaining to
any Replacement Mortgage Loans, the Trustee shall release, or cause to be
released, the Trustee Mortgage File held for the benefit of the
Certificateholders relating to such Deleted Mortgage Loan to the Mortgage Loan
Seller or Master Servicer as applicable and shall execute and deliver such
instruments of transfer or assignment, in each case without recourse, as shall
be necessary to vest title (to the extent that such title was transferred to the
Trustee) in the Mortgage Loan Seller or Master Servicer as applicable, or its
designee, to any Deleted Mortgage Loan substituted for pursuant to this Section
2.04(b).

         In any month in which the Mortgage Loan Seller or Master Servicer
substitutes one or more Replacement Mortgage Loans for one or more Deleted
Mortgage Loans, the Master Servicer will determine the Replacement Amount (if
any) (after application of scheduled principal portion of the Monthly Payments
received in the month of substitution). Such Replacement Amount shall be
deposited into the Custodial Account by the Mortgage Loan Seller or Master
Servicer in the month of substitution pursuant to Section 3.07, without any
reimbursement thereof. The Master Servicer shall give notice in writing to the
Trustee of such event, which notice shall be accompanied by a certificate of a
Servicing Officer as to the calculation of such shortage.

         In the event that the Mortgage Loan Seller or Master Servicer shall
have repurchased a Mortgage Loan, upon receipt by the Trustee of written
notification of the deposit of the Purchase Price, the Trustee shall release, or
cause to be released, the related Trustee Mortgage File held for the benefit of
the Certificateholders to the Mortgage Loan Seller or Master Servicer as
applicable and the Trustee shall execute and deliver the related instruments of
transfer or assignment, in each case without recourse, as shall be necessary to
transfer title (to the extent that such title was transferred to the Trustee)
from the Trustee for the benefit of the Certificateholders and vest title in the
Mortgage Loan Seller or Master Servicer, or the designee thereof, as the case
may be, to any Mortgage Loan purchased pursuant to this Section 2.04(b). It is
understood and agreed that the

                                       38

<PAGE>

obligation under this Agreement of any Person to repurchase or substitute any
Mortgage Loan as to which such breach has occurred and is continuing shall
constitute the sole and exclusive remedy respecting such breach available to
Certificateholders or the Trustee on their behalf.

         SECTION 2.05      ISSUANCE OF CERTIFICATES.
                           ------------------------

         The Trustee acknowledges the assignment to it of the Mortgage Loans
together with the assignment to it of all other assets included in the Trust
Fund. Concurrently with such assignment and delivery, the Trustee, pursuant to
the written request of the Seller executed by an officer of the Seller, has
executed the Class A, Class M-1, Class M-2, Class M-3, Class B-1, Class B-2,
Class B-3 and Class R Certificates and caused them to be authenticated and
delivered to or upon the order of the Seller in authorized denominations which
evidence ownership of the Trust Fund. The rights of the Holders of such
Certificates to receive distributions from the Trust Fund and all ownership
interests of the Holders of the Class A, Class M-1, Class M-2, Class M-3, Class
B-1, Class B-2, Class B-3 and Class R Certificates in such distributions shall
be as set forth in this Agreement.

         SECTION 2.06      REMIC PROVISIONS.
                           ----------------

         (a) As set forth in the Preliminary Statement hereto, the Trustee shall
elect to treat the Trust Fund as a REMIC in accordance with the REMIC
Provisions. The Trustee shall make such election on Form 1066 or other
appropriate federal tax or information return for the taxable year ending on the
last day of the calendar year in which the Certificates are issued. For the
purposes of such election, each Class of Certificates, other than the Class R
Certificates, is hereby designated as a regular interest in the REMIC, and the
Class R Certificates are hereby designated as the sole residual interest in the
REMIC.

         (b) The Closing Date is hereby designated as the "Startup Day" of each
REMIC within the meaning of section 86OG(a)(9) of the Code.

         (c) The Trustee shall pay any and all tax related expenses (not
including taxes) of the REMIC, including but not limited to any professional
fees or expenses related to audits or any administrative or judicial proceedings
with respect to such REMIC that involve the Internal Revenue Service or state
tax authorities, but only to the extent that (i) such expenses are ordinary or
routine expenses, including expenses of a routine audit but not expenses of
litigation (except as described in (ii)); or (ii) such expenses or liabilities
(including taxes and penalties) are attributable to the negligence or willful
misconduct of the Trustee in fulfilling its duties hereunder (including its
duties as tax return preparer). The Trustee shall be entitled to reimbursement
of expenses to the extent provided in clause (i) above from the Certificate
Account.

         (d) The Trustee shall prepare, sign and timely file, all of the REMIC's
federal and state tax and information returns as such REMIC's direct
representative. The expenses of preparing and filing such returns shall be borne
by the Trustee.

         (e) The Trustee or its designee shall perform as directed by the Master
Servicer on behalf of the REMIC all reporting and other tax compliance duties
that are the responsibility of such REMIC under the Code, the REMIC Provisions,
or other compliance guidance issued by the Internal

                                       39

<PAGE>

Revenue Service or any state or local taxing authority. Among its other duties,
if required by the Code, the REMIC Provisions, or other such guidance, the
Trustee shall provide (i) to the Treasury or other governmental authority such
information as is necessary for the application of any tax relating to the
transfer of a Residual Certificate to any disqualified person or organization
and (ii) to the Certificateholders such information or reports as are required
by the Code or REMIC Provisions.

         (f) The Trustee, the Master Servicer and the Holders of Certificates
shall take any action or cause the REMIC to take any action necessary to create
or maintain the status of such REMIC as a REMIC under the REMIC Provisions and
shall assist each other as necessary to create or maintain such status. Neither
the Trustee, the Master Servicer nor the Holder of any Residual Certificate
shall take any action, cause the REMIC 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 such REMIC as
a REMIC or (ii) result in the imposition of a tax upon such REMIC (including but
not limited to the tax on prohibited transactions as defined in Code Section
860F(a)(2) and the tax on prohibited contributions set forth on Section 860G(d)
of the Code) (either such event, an "Adverse REMIC Event") unless the Trustee
and the Master Servicer have received an Opinion of Counsel (at the expense of
the party seeking to take such action) to the effect that the contemplated
action will not endanger such status or result in the imposition of such a tax.
In addition, prior to taking any action with respect to the REMIC or the assets
therein, or causing such REMIC to take any action, which is not expressly
permitted under the terms of this Agreement, any Holder of a Residual
Certificate will consult with the Trustee and the Master Servicer, or their
respective designees, in writing, with respect to whether such action could
cause an Adverse REMIC Event to occur with respect to such REMIC, and no such
Person shall take any such action or cause such REMIC to take any such action as
to which the Trustee or the Master Servicer has advised it in writing that an
Adverse REMIC Event could occur.

         (g) Each Holder of a Residual Certificate shall pay when due any and
all taxes imposed on the REMIC by federal or state governmental authorities. To
the extent that such Trust taxes are not paid by a Residual Certificateholder,
the Trustee shall pay any remaining REMIC taxes out of current or future amounts
otherwise distributable to the Holder of the Residual Certificate in the REMIC
or, if no such amounts are available, out of other amounts held in the
Certificate Account, and shall reduce amounts otherwise payable to holders of
regular interests in the REMIC.

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

         (i) Within 30 days after the Closing Date, the Trustee shall prepare
and file with the Internal Revenue Service Form 8811, "Information Return for
Real Estate Mortgage Investment Conduits (REMIC) and Issuers of Collateralized
Debt Obligations" for the REMIC.

         (j) Neither the Trustee nor the Master Servicer shall sell, dispose of
or substitute for any of the Mortgage Loans (except in connection with (i) the
default, imminent default or 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 the Trust Fund pursuant to Article X of this Agreement or (iv) a
purchase of Mortgage Loans

                                       40

<PAGE>

pursuant to Article II or III of this Agreement) nor acquire any assets for the
Trust Fund, nor sell or dispose of any investments in the Custodial Account or
the Certificate Account for gain nor accept any contributions to the Trust Fund
after the Closing Date (a) unless it has received an Opinion of Counsel that
such sale, disposition, substitution or acquisition will not affect adversely
the status of the Trust Fund as a REMIC or (b) unless the Master Servicer has
determined in its sole discretion to indemnify the Trust Fund against such tax.

         (k) In order to enable the Trustee to perform its duties as set forth
herein, the Seller shall provide, or cause to be provided to the Trustee, within
ten days after the Settlement Date, all information or data that the Trustee
determines to be relevant for tax purposes to the valuations and offering prices
of the Certificates, including, without limitation, the price, yield, prepayment
assumption and projected cash flows of the Certificates and the Mortgage Loans
and the Trustee shall be entitled to rely upon any and all such information and
data in the performance of its duties set forth herein. Thereafter, the Master
Servicer shall provide, promptly upon request therefor, any such additional
information or data that the Trustee may from time to time reasonably request in
order to enable the Trustee to perform its duties as set forth herein and the
Trustee shall be entitled to rely upon any and all such information and data in
the performance of its duties set forth herein. The Seller shall indemnify the
Trustee and hold it harmless for any loss, liability, damage, claim or expense
of the Trustee arising from any failure of the Seller to provide, or to cause to
be provided, accurate information or data to the Trustee on a timely basis. The
Master Servicer shall indemnify the Trustee and hold it harmless for any loss,
liability, damage, claim or expense of the Trustee arising from any failure of
the Master Servicer to provide, or to cause to be provided, accurate information
or data to the Trustee on a timely basis. The indemnification provisions
hereunder shall survive the termination of this Agreement and shall extend to
any co-trustee appointed pursuant to this Agreement.

         (l) The Department of Labor has granted administrative exemptions to
Bear, Stearns & Co. Inc. (Prohibited Transaction Exemption 90-30, 55 F.R.
21455), Credit Suisse First Boston Corporation (Prohibited Transaction Exemption
89-90, 55 F.R. 42581) and Greenwich Capital Markets, Inc. (Prohibited
Transaction Exemption 90-59, 55 F.R. 36724), each as amended (each an
"Exemption") from certain of the prohibited transaction rules of ERISA and the
Code.

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

         SECTION 3.01      SERVICING STANDARD.
                           ------------------

         (a) For and on behalf of the Trustee and the Certificateholders, the
Master Servicer shall service and administer the Mortgage Loans in accordance
with prudent mortgage loan servicing standards and procedures generally accepted
in the mortgage banking industry and generally in a manner consistent with
Fannie Mae guidelines except as otherwise expressly provided in this Agreement.
In connection with such servicing and administration, the Master Servicer shall
have full power and authority, acting alone and/or through any Sub-Servicer as
provided in Section 3.02 hereof, 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 (1) to execute and deliver, on behalf of the
Certificateholders and the Trustee, customary consents or waivers and other
instruments and documents (including, without limitation, estoppel
certificates), (ii) to consent to transfers of any Mortgaged Property and
assumptions of the Mortgage Notes and related Mortgages (but only in the manner
provided in this Agreement), (iii) to collect any Insurance Proceeds and
Liquidation Proceeds, (iv) to consent to any subordinate financings to be
secured by any Mortgaged Property to the extent that such consent is required
pursuant to the terms of the related Mortgage, (v) to consent to the application
of any proceeds of insurance policies or condemnation awards to the restoration
of the applicable Mortgaged Property or otherwise, and (vi) subject to the
provisions of Section 3.07 and 3.13, to effectuate foreclosure or other
conversion of the ownership of the Mortgage Property securing any Mortgage Loan;
provided, however, that the Master Servicer shall take no action that is
materially inconsistent with or materially prejudices the interest of the
Trustee or the Certificateholders in any Mortgage Loan or the rights and
interest of the Seller, the Trustee and the Certificateholders under the terms
of this Agreement unless such action is specifically called for by the terms
hereof.

         (b) Without limiting the generality of the foregoing, but subject to
the terms hereof, the Master Servicer, in its own name or in the name of the
Trustee, is hereby authorized and empowered by the Seller and the Trustee, when
the Master Servicer believes it appropriate in its best judgment, to execute and
deliver, on behalf of the Trustee, the Certificateholders or any of them, any
and all instruments of modification, satisfaction, cancellation or assignment,
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
promptly notify the Trustee of any such execution and delivery. The Trustee for
the benefit of the Certificateholders shall execute any powers of attorney and
other documents necessary or appropriate to enable the Master Servicer to
service and administer the Mortgage Loans.

         (c) 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,
imminent) permit any modification with respect to any Mortgage Loan (i) that
would change the Net Mortgage Rate or, reduce or increase the principal balance

                                       42

<PAGE>

(except for increases resulting from the addition of Deferred Interest and
reductions resulting from actual payments of principal) or (ii) that would both
constitute a sale or exchange of such Mortgage Loan within the meaning of
Section 1001 of the Code (including any proposed, temporary or final regulations
promulgated thereunder) (other than in connection with a proposed conveyance or
assumption of such Mortgage Loan that is a Principal Prepayment made (or treated
as made) by the Mortgagor of the entire principal balance of a Mortgage Loan)
and cause the Trust Fund to fail to qualify as a REMIC under the Code.

         (d) If an Index of One-Year MTA is no longer available, the Master
Servicer will choose a new Index which is based on comparable information. In
such event, the Master Servicer will also determine a new Gross Margin. The new
Gross Margin will be the difference between the average of One-Year MTA for the
most recent three-year period which ends on the last date One-Year MTA was
available plus the Gross Margin on the last date One-Year MTA was available and
the average of the new index for the most recent three year period which ends on
that date (or, if not available for such three-year period, for such time as it
is available), rounded as provided in the Mortgage Note.

         SECTION 3.02      ENFORCEMENT OF THE OBLIGATIONS OF SUB-SERVICERS.
                           -----------------------------------------------

         (a) For purposes of this Agreement, the Master Servicer shall be deemed
to have received the payments on the Mortgage Loans referred to in Sections 3.07
and 3.08 hereof when the related Sub-Servicer, if any, has received such
payments and shall remain obligated to deposit such payments in accordance with
Sections 3.07 and 3.08 hereof, regardless of whether such payments are remitted
by the Sub-Servicer to the Master Servicer. The Master Servicer and the related
Sub-Servicer may enter into amendments to any applicable Sub-Servicing
Agreement; provided, however, that any such amendments shall be consistent with
and shall not violate the provisions of this Agreement.

         (b) As part of its servicing activities hereunder, the Master Servicer,
for the benefit of the Seller, the Trustee and the Certificateholders, shall
supervise, administer, monitor and oversee the servicing of the Mortgage Loans
that are not serviced by it directly, and shall enforce the obligations of each
Sub-Servicer, if any, under the related Sub-Servicing Agreement. Such
enforcement shall include, without limitation, the legal prosecution of claims,
termination of Sub-Servicing Agreements, as appropriate, and the pursuit of
other appropriate remedies, and 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, 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 Loans or (ii) from a specific
recovery of costs, expenses or attorneys fees against the party against whom
such enforcement is directed. The Master Servicer shall not waive any event of
default by a Sub-Servicer under a Sub-Servicing Agreement which is a failure to
remit any payment required to be made by such Sub-Servicer that would result in
an Event of Default under this Agreement.

         (c) During the term of this Agreement, the Master Servicer shall
consult fully with each of the Sub-Servicers as may be necessary from time to
time to perform and carry out the Master

                                       43

<PAGE>

Servicer's obligations hereunder and receive, review and evaluate all reports,
information and other data that are provided to the Master Servicer by each
Sub-Servicer and otherwise exercise reasonable efforts to cause each
Sub-Servicer to perform and observe the covenants, obligations and conditions to
be performed or observed by it under its Sub-Servicing Agreement.

         SECTION 3.03      TERMINATION OF THE RIGHTS OF SUB-SERVICERS.
                           ------------------------------------------

         If the Master Servicer terminates the rights of a Sub-Servicer under
any Sub-Servicing Agreement, the Master Servicer shall service the Mortgage
Loans directly pursuant to and in accordance with the terms of this Agreement,
or at the Master Servicer's election, enter into a substitute servicing
agreement with another mortgage loan servicing company reasonably acceptable to
the Master Servicer under which such mortgage loan servicing company shall
assume, satisfy, perform and carry out all liabilities, duties, responsibilities
and obligations that are to be, or otherwise were to have been, satisfied,
performed and carried out by the terminated Sub-Servicer, regardless of whether
such liabilities, duties, responsibilities or obligations shall have accrued
before or after the termination of the rights of such Sub-Servicer; provided,
however, that any such substitute servicer and any such substitute servicing
shall satisfy the requirements of Sections 3.01 and 3.02. If the Master Servicer
does not elect to enter into a substitute servicing agreement with a successor
servicer, the Master Servicer shall nevertheless service the Mortgage Loans
directly pursuant to and in accordance with the terms of this Agreement, until a
substitute Sub-Servicer has been appointed and designated and a substitute
servicing agreement has been entered into by the Master Servicer and such
substitute Sub-Servicer.

         SECTION 3.04      LIABILITY OF THE MASTER SERVICER.
                           --------------------------------

         Notwithstanding the provisions of any Sub-Servicing Agreement, any of
the provisions of this Agreement relating to agreements or arrangements between
the Master Servicer or a Sub-Servicer or reference to actions taken through a
Sub-Servicer or otherwise, the Master Servicer shall remain obligated and liable
to the Seller, the Trustee and the Certificateholders for the servicing and
administering of the Mortgage Loans included in the Trust Fund in accordance
with (and subject to the limitations contained within) the provisions of this
Agreement without diminution of such obligation or liability by virtue of such
Sub-Servicing Agreements or 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. The Master Servicer shall be entitled to enter
into any agreement with a Sub-Servicer for indemnification of the Master
Servicer and nothing contained in this Agreement shall be deemed to limit or
modify such indemnification.

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

         The Master Servicer shall afford the Seller and the Trustee, without
charge but only upon reasonable notice and during normal business hours, access
to all records and documentation in the Master Servicer's possession regarding
the Mortgage Loans and to all accounts, insurance policies and other matters in
the Master Servicer's possession relating to this Agreement and access to
officers of the Master Servicer responsible for its obligations hereunder. The
Seller may, but is not

                                       44

<PAGE>

obligated to, enforce the obligations of the Master Servicer hereunder. The
Seller shall not have any responsibility or liability for any action or failure
to act by the Master Servicer and is not obligated to supervise the performance
of the Master Servicer hereunder or otherwise.

         SECTION 3.06      TRUSTEE TO ACT AS MASTER SERVICER.
                           ---------------------------------

         In the event that the Master Servicer shall for any reason no longer be
the Master Servicer hereunder (including by reason of an Event of Default), the
Trustee shall thereupon assume all of the rights and obligations of the Master
Servicer hereunder arising thereafter (except that the Trustee shall not be
liable for losses in connection with Eligible Investments required to be paid by
the Master Servicer pursuant to Section 3.07 or 4.01 hereof, obligated to make
Monthly Advances if prohibited by applicable law, nor to effectuate repurchases
or substitutions of Mortgage Loans hereunder as substitute Master Servicer,
including pursuant to Section 2.04 hereof and except that the Trustee makes no
representations and warranties hereunder, including pursuant to Section 2.04
hereof). If the Master Servicer shall for any reason no longer be the Master
Servicer (including by reason of any Event of Default), the Trustee (or any
other successor master servicer) shall succeed to any rights and obligations of
the Master Servicer under any Sub-Servicing Agreement and shall be deemed to
have assumed the Master Servicer's interest therein; provided, however, that the
Master Servicer shall not thereby be relieved of any liability or obligations
under this Agreement, any Sub-Servicing or substitute servicing agreement
arising prior to the date of such succession.

         The Master Servicer shall, upon request of the Trustee, but at the
expense of the Master Servicer, deliver to the assuming party all documents and
records relating to the Mortgage Loans then being serviced thereunder and an
accounting of amounts collected and held by it and otherwise use its best
efforts to effect the orderly and efficient transfer of servicing to the
assuming party.

         SECTION 3.07      COLLECTION OF MORTGAGE LOAN PAYMENTS.
                           ------------------------------------

         (a) 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,
follow such collection procedures as it follows with respect to mortgage loans
comparable to the Mortgage Loans held in its own portfolio and serviced by the
Master Servicer. Consistent with the foregoing, the Master Servicer may in its
discretion (a) waive any late payment charge or any prepayment charge or penalty
interest in connection with the prepayment of a Mortgage Loan and (b) subject to
Section 3.01, only upon determining that the coverage of such Mortgage Loan by
any related Primary Mortgage Insurance Policy will not be affected, extend the
due dates for payments due on a Mortgage Note for a period not greater than 365
days, but in no event beyond the maturity date of any Mortgage Loan. In the
event of any such arrangement described in clause (b) of the preceding sentence,
the Master Servicer shall continue to make timely Monthly Advances on the
related Mortgage Loan, pursuant to and in accordance with Section 5.04 of this
Agreement (but subject to any limitations contained therein), during the
scheduled period in accordance with the amortization schedule of such Mortgage
Loan without modification thereof by reason of such arrangements.

         (b) The Master Servicer shall establish and maintain, in its name on
behalf of the Certificateholders, the Custodial Account. The Master Servicer
shall deposit into the Custodial

                                       45

<PAGE>

Account within two Business Days of receipt by the Master Servicer, or receipt
from the Sub-Servicers except as otherwise specifically provided herein, the
following payments and collections received or made by it subsequent to the
Cut-off Date (other than in respect of principal of and interest and any other
payments on the Mortgage Loans due on or before the Cut-off Date):

                  (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
         less the Servicing Fee, and the Retained Interest;

                  (iii) all Insurance Proceeds and 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, net of Liquidation
         Expenses, unpaid servicing compensation and unreimbursed Monthly
         Advances;

                  (iv) any amount of any losses required to be deposited by the
         Master Servicer pursuant to Section 3.07(c) in connection with any
         losses on Eligible Investments;

                  (v) any amounts required to be deposited by the Master
         Servicer pursuant to Section 3.11 hereof;

                  (vi) all proceeds of any purchase by the Mortgage Loan Seller
         or the Master Servicer, as the case may be, of any Mortgage Loans or
         property acquired in respect of the Mortgage Loans pursuant to Sections
         2.01, 2.02, 2.03, 2.04, 3.12 or 10.01 hereof and any Replacement
         Amounts required to be deposited in connection with the substitution of
         Replacement Mortgage Loans pursuant to Sections 2.01, 2.02, 2.03, 2.04
         or 3.12 hereof; and

                  (vii) any other amounts required to be deposited in the
         Custodial Account pursuant to this Agreement including, without
         limitation, the amounts required to be deposited therein pursuant to
         Section 3.13 hereof.

         The foregoing requirements for remittance by the Master Servicer shall
be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, the Servicing Fee, payments in the nature of
prepayment penalties, fees or premiums, late payment charges and assumption fees
and any excess interest charges payable by the Mortgagor by virtue of any
default or other non-compliance by the Mortgagor with the terms of the Mortgage
or any other instrument or document executed in connection therewith or
otherwise, if collected, need not be remitted or deposited into the Custodial
Account by the Master Servicer. In the event that the Master Servicer shall
remit or deposit any amount not required to be remitted or deposited and not
otherwise subject to withdrawal pursuant to Section 3.09 hereof, it may at any
time withdraw such amount from the Custodial Account on the following
Distribution Date, any provision herein to the contrary notwithstanding. All
funds deposited in the Custodial Account shall be held by the Master Servicer in
trust for the Certificateholders until disbursed in accordance with this
Agreement or withdrawn in accordance with Section 3.09. In no event shall the
Trustee incur liability for withdrawals from the Custodial Account at the
direction of the Master Servicer.

                                       46

<PAGE>

         (c) Any investments of amounts on deposit in the Custodial Account
shall be made by the Master Servicer in Eligible Investments, which shall mature
not later than the second Business Day preceding the Distribution Date following
the date of such investment (except that if such Eligible Investment is an
obligation of the institution that maintains the Custodial Account, then such
Eligible Investment shall mature not later than such Distribution Date). All
such Eligible 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 and shall be subject to withdrawal at its direction from time to time.
The amount of any losses net of any gains incurred by the Master Servicer in
respect of any such investments shall be remitted to the Trustee or deposited in
the Custodial Account out of the Master Servicer's own funds promptly following
the date the same are realized.

         (d) The Master Servicer shall promptly give notice to the Trustee, the
Rating Agencies and the Seller of the location of the Custodial Account and of
any change thereof.

         SECTION 3.08      COLLECTION OF TAXES, ASSESSMENTS AND SIMILAR ITEMS;
                           ESCROW ACCOUNTS.
                           ---------------------------------------------------

         (a) In addition to the Custodial Account, the Master Servicer shall
establish and maintain one or more custodial accounts (each, an "Escrow
Account") and deposit and retain therein all collections from the Mortgagors (or
advances by the Master Servicer) for the payment of taxes, assessments and
hazard insurance premiums or comparable items for the account of the Mortgagors.
Escrow Accounts shall be Eligible Accounts. All costs incurred by the Master
Servicer or by the related Sub-Servicer 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 Scheduled Principal Balance under the
related Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so
permit.

         (b) Withdrawals of amounts so collected from the Escrow Accounts may be
made only to effect timely payment of taxes, assessments, hazard insurance
premiums or Primary Mortgage Insurance Policy premiums, condominium or PUD
association dues, or comparable items, to reimburse the Master Servicer pursuant
to Section 3.10 hereof (with respect to the Primary Mortgage Insurance Policy)
and this Section 3.08 (with respect to taxes and assessments) and Section 3.11
hereof (with respect to hazard insurance), to refund to any Mortgagors any sums
as may be determined to be overages, to pay interest, if required, 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 hereof. As
part of its servicing duties, the Master Servicer shall, and the Sub-Servicers
shall, pursuant to any Sub-Servicing Agreement, be required to, pay to the
Mortgagors interest on funds in the Escrow Account, to the extent required by
law.

         (c) The Master Servicer shall, with respect to each Mortgage Loan, to
the extent any related Sub-Servicer does not do so, advance the payments
referred to in Section 3.08(b) that are not timely paid by the Mortgagors;
provided, however, that the Master Servicer shall be required to so advance only
to the extent that such advances, in the good faith judgment of the Master
Servicer, will be recoverable by the Master Servicer out of Insurance Proceeds,
Liquidation Proceeds or otherwise

                                       47

<PAGE>

out of the related Mortgage Loan; and provided further, that such payments shall
be advanced when the tax, premium or other cost for which such payment is
intended is due.

         SECTION 3.09      PERMITTED WITHDRAWALS FROM THE CUSTODIAL ACCOUNT.
                           ------------------------------------------------

         (a) The Master Servicer may (and, with respect to clauses (v) and (vii)
below, shall), from time to time, make, to the extent required or authorized
hereunder, withdrawals from the Custodial Account for the following purposes:

                  (i) to pay to the Master Servicer from funds on deposit in the
         Custodial Account earnings on or investment income with respect to
         funds in the Custodial Account less losses referred to in Section
         3.07(iv);

                  (ii) to reimburse the Master Servicer for advances made
         pursuant to Sections 3.01, 3.08, 3.10, 3.11, 3.13, 5.04 and 5.05
         hereof, such right of reimbursement pursuant to this subclause (ii)
         being limited to amounts received in respect of the particular Mortgage
         Loan (including, for this purpose, Insurance Proceeds, Liquidation
         Proceeds, amounts representing proceeds of other insurance policies, if
         any, covering the related Mortgaged Property, rental and other income
         from REO Property and proceeds of any purchase or repurchase of the
         related Mortgage Loan);

                  (iii) to reimburse the Master Servicer for any Nonrecoverable
         Advances made in respect of any Mortgage Loan;

                  (iv) to reimburse the Master Servicer from Liquidation
         Proceeds for Liquidation Expenses and, to the extent that Liquidation
         Proceeds after such reimbursement are in excess of the Scheduled
         Principal Balance of the related Mortgage Loan together with accrued
         and unpaid interest thereon at a rate equal to the Mortgage Rate, to
         pay out of such excess the amount of any unpaid servicing compensation
         to the Master Servicer with respect to any Mortgage Loan, which may
         include any unpaid servicing compensation to a Sub-Servicer (for
         disbursement in accordance with Section 3.16 hereof);

                  (v) to pay to the Mortgage Loan Seller or the Master Servicer,
         as the case may be, with respect to each Mortgage Loan or property
         acquired in respect thereof that has been purchased pursuant to
         Sections 2.01, 2.02, 2.04 or 3.12 hereof all amounts received thereon
         and not taken into account in determining the Purchase Price of such
         repurchased Mortgage Loan;

                  (vi) to reimburse the Master Servicer or the Seller for
         expenses incurred by and reimbursable to the Master Servicer or the
         Seller pursuant to Section 7.03 hereof or Section 9.10(f);

                  (vii) to withdraw any amount deposited in the Custodial
         Account pursuant to Section 3.07 and not required to be deposited
         therein; and

                                       48

<PAGE>

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

         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 Custodial Account pursuant to such subclauses (ii) through
(v).

         (b) On or prior to the Servicer Remittance Date, after payment of items
(i) through (ix) of Section 3.09(a), the Master Servicer shall withdraw from the
Custodial Account and remit the following:

                  (i) to the PMI Insurer, the PMI Insurance Premium for such
                  Servicer Remittance Date;

                  (ii) to the Trustee, in immediately available funds, an amount
                  equal to the Total Distribution Amount for such Distribution
                  Date, which the Trustee, upon receipt thereof, shall deposit
                  in the Certificate Account.

         SECTION 3.10      MAINTENANCE OF PRIMARY MORTGAGE INSURANCE POLICIES
                           AND PMI POLICY; COLLECTIONS THEREUNDER.
                           --------------------------------------------------

         (a) The Master Servicer shall not take, or permit any Sub-Servicer to
take, any action that would result in loss of coverage under any applicable
Primary Mortgage Insurance Policy for any loss which, but for the actions of the
Master Servicer or Sub-Servicer, would have been covered thereunder.

         (b) The Master Servicer shall keep in full force and effect each
Primary Mortgage Insurance Policy applicable to a Mortgage Loan being serviced
by it until the principal balance of the related Mortgage Loan, in the case of a
Mortgage Loan having a Loan-to-Value Ratio at origination in excess of 80%, is
reduced to (i) 80% or less of the Appraised Value or (ii) 80% or less of its
current value based on a new appraisal. The Master Servicer agrees to pay to the
extent the related Mortgagor does not do so, the premiums for each Primary
Mortgage Insurance Policy on a timely basis and shall use its best reasonable
efforts to cause itself or the Sub-Servicer to be named as loss payee; provided,
however, that the Master Servicer shall be required to pay such premiums only to
the extent that such advances, in the good faith judgment of the Master
Servicer, will be recoverable by the Master Servicer out of Insurance Proceeds,
Liquidation Proceeds or otherwise out of the related Mortgage Loan. In the event
that the insurer under any Primary Mortgage Insurance Policy shall cease to be
qualified to transact a mortgage guaranty insurance business under the laws of
the state of its organization or any other state that has jurisdiction over such
insurer (or if such insurer's claims-paying ability shall adversely affect the
rating on the Class A Certificates) or such Primary Mortgage Insurance Policy is
cancelled or terminated for any reason, the Master Servicer shall exercise its
best reasonable efforts to obtain, or to cause the related Sub-Servicer to
obtain, from another Qualified Insurer, a replacement policy comparable to such
Primary Mortgage Insurance Policy at the expense of the Mortgagor. The Master
Servicer shall not consent to the cancellation or refusal to renew any such
Primary Mortgage Insurance Policy applicable to any Mortgage Loan, which is in
effect at the date of the initial issuance of the Certificates and is required

                                       49

<PAGE>

to be kept in force hereunder unless the replacement Primary Mortgage Insurance
Policy for such cancelled or non-renewed policy is maintained with an insurer
with a rating not lower than the insurer issuing the Primary Mortgage Insurance
Policy in effect at the date of the initial issuance of the Certificates or
whose claims-paying will not adversely affect the rating on the Certificates or
unless any such cancellation or refusal, or consent thereto, will not adversely
affect the rating on the Certificates. In connection with any assumption and
modification agreement entered into by the Master Servicer or a Sub-Servicer
pursuant to Section 3.12, the Master Servicer shall obtain a replacement Primary
Mortgage Insurance Policy, as provided above.

         (c) The Master Servicer shall cooperate with the PMI Insurer and shall
use its best efforts to furnish to the PMI Insurer all reasonable information in
the possession of the Master Servicer or to which the Master Servicer has access
with respect to each Mortgage Loan.

         (d) In the event of a default by the PMI Insurer under the 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 Seller, 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 PMI
Policy.

         (e) In connection with its activities as administrator and servicer of
the Mortgage Loans, the Master Servicer agrees to present, on behalf of itself,
and on behalf of the Trustee for the benefit of the Certificateholders, claims
to the insurer under any Primary Mortgage Insurance Policies and claims to the
PMI Insurer with respect to the PMI Policy and, in this regard, to take such
reasonable action as shall be necessary to permit recovery under any Primary
Mortgage Insurance Policies or the PMI Policy respecting defaulted Mortgage
Loans. Pursuant to Section 3.07 hereof, any amounts collected by the Master
Servicer under any Primary Mortgage Insurance Policy or the PMI Policy shall be
deposited in the Custodial Account, subject to withdrawal pursuant to Section
3.09 hereof.

         SECTION 3.11      MAINTENANCE OF HAZARD INSURANCE AND OTHER INSURANCE.
                           ---------------------------------------------------

         (a) The Master Servicer shall cause to be maintained for each Mortgage
Loan, hazard insurance with extended coverage in an amount that is at least
equal to the replacement cost of improvements securing such Mortgage Loan or its
Scheduled Principal Balance, whichever is less.

         (b) Each policy of standard hazard insurance shall contain, or have an
accompanying endorsement that contains, a standard mortgagee clause complying in
all material respects in form and substance to applicable Fannie Mae guidelines.
The Master Servicer shall cause to be maintained on property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan, liability
insurance and, to the extent described below, flood insurance. Pursuant to
Section 3.07 hereof, any amounts collected by the Master Servicer under any such
policies (other than

                                       50

<PAGE>

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 terms of the applicable Mortgage or the Master Servicer's
normal servicing procedures) shall be deposited in the Custodial Account,
subject to withdrawal pursuant to Section 3.09 hereof.

         Any cost incurred by the Master Servicer or the related Sub-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 Scheduled 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 payments by the related Mortgagor
or out of Insurance Proceeds or Liquidation Proceeds to the extent permitted by
Section 3.09 hereof. If the Mortgaged Property is located at the time of
origination of the Mortgage Loan in a federally designated special flood hazard
area, the Master Servicer shall cause flood insurance to be maintained. Such
flood insurance shall be in an amount equal to the lesser of (i) the unpaid
Scheduled Principal Balance of the related Mortgage Loan or (ii) the maximum
amount of such insurance available for the related Mortgaged Property under the
national flood insurance program, if the area in which such Mortgaged Property
is located is participating in such program. Notwithstanding anything in this
paragraph to the contrary, the Master Servicer shall be required to pay the
costs of maintaining any insurance contemplated by this Section 3.11 only to the
extent that such advances, in the good faith judgment of the Master Servicer,
will be recoverable by the Master Servicer out of Insurance Proceeds,
Liquidation Proceeds or otherwise out of the related Mortgage Loan.

         (c) 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 Section 3.11(a), 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, and
provided that the provider of such blanket policy is rated by A.M. Best Company
A:V or higher and the claims-paying ability of such provider is rated in one of
the three highest rating categories by at least one nationally recognized
statistical rating organization. If such policy contains a deductible clause,
the Master Servicer shall, to the extent that there shall not have been
maintained on the related Mortgaged Property a policy complying with the first
sentence of Section 3.11(a) and there shall have been a loss that would have
been covered by such policy, remit to the Trustee for deposit in the Custodial
Account the amount not otherwise payable under the blanket policy because of
such deductible clause, accompanied by a certificate of a Servicing Officer
describing the calculation of such amount. 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, the Trustee or its agent for the
benefit of the Certificateholders, claims under any such blanket policy.

         SECTION 3.12      ENFORCEMENT OF DUE-ON-SALE CLAUSES; ASSUMPTION
                           AGREEMENTS.
                           ----------------------------------------------

         (a) Except as otherwise provided in this Section 3.12(a), when any
property subject to a Mortgage has been 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

                                       51

<PAGE>

Insurance Policy. In the event that the Master Servicer or the related
Sub-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, the
Master Servicer is authorized, subject to Section 3.12(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. The Master
Servicer, subject to Section 3.12(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 3.12(a) by reason of any transfer or assumption which the Master
Servicer is restricted by law from preventing, for any reason whatsoever.

         (b) Subject to the Master Servicer's duty to enforce any due-on-sale
clause to the extent set forth in Section 3.12(a) hereof, in any case in which a
Mortgaged Property has been conveyed to a Person by a Mortgagor, if an
assumption is permitted under Section 3.12(a) and such Person is to enter into
an assumption agreement or modification agreement or supplement to the Mortgage
Note or Mortgage held for the benefit of the Certificateholders 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 deliver or cause to be delivered to the Trustee for
signature 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 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. The Master Servicer shall also deliver or cause to be
delivered to the Trustee with the foregoing documents a letter explaining the
nature of such documents and the reason or reasons why the Trustee's signature
is required.

         With such letter, the Master Servicer shall deliver to the Trustee a
certificate of a Servicing Officer certifying that: (i) a Servicing Officer has
examined and approved such documents as to form and substance, (ii) the
Trustee's execution and delivery thereof will not conflict with or violate any
terms of this Agreement or cause the unpaid balance and interest on the Mortgage
Loan to be uncollectible in whole or in part, (iii) any required consents of
insurers under any Required Insurance Policies have been obtained and (iv)
subsequent to the closing of the transaction involving the assumption or
transfer (A) the Mortgage Loan will continue to be secured by a first mortgage
lien pursuant to the terms of the Mortgage, (B) such transaction will not
adversely affect the coverage under any Required Insurance Policies, (C) the
Mortgage Loan will fully amortize over the remaining term thereof or, if the
Mortgage Loan provided that the amortization period on which the Monthly
Payments were based was a longer period, such period has not been extended, (D)
the interest rate on the Mortgage Loan will not be altered nor will the term of
the Mortgage Loan be increased as a result of such assumption or transfer and
(E) if the seller/transferor of the Mortgaged Property is to be released from
liability on the Mortgage Loan, the Master Servicer used the same underwriting
standards in evaluating the creditworthiness of the purchaser/transferee as were
used in making the

                                       52

<PAGE>

original Mortgage Loan, and, based on such underwriting criteria, such release
will not (based on the Master Servicer's good faith determination) adversely
affect the collectibility of the Mortgage Loan. Upon receipt of such
certificate, the Trustee for the benefit of the Certificateholders shall execute
any necessary instruments for such assumption or substitution of liability. Upon
the closing of the transactions contemplated by such documents, the Master
Servicer shall cause the originals of the assumption agreement, the release (if
any), or the modification or supplement to the Mortgage Note or Mortgage to be
delivered to the Trustee or its agent for the benefit of the Certificateholders
and deposited with the Trustee Mortgage File for such Mortgage Loan. 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.

         In the event that the Master Servicer, in connection with any such
assumption or modification agreement or supplement to the Mortgage Note, is
unable to deliver the certificate of the Servicing Officer set forth above, the
Master Servicer shall purchase, or cause the related Sub-Servicer to purchase,
the related Mortgage Loan in the manner, and at the Purchase Price, set forth in
Section 2.04(b) hereof.

         SECTION 3.13      REALIZATION UPON DEFAULTED MORTGAGE LOANS.
                           -----------------------------------------

         (a) The Master Servicer shall 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, in the reasonable judgment of the
Master Servicer, no satisfactory arrangements can, in accordance with prudent
lending practices, be made for collection of delinquent payments pursuant to
Section 3.01 hereof. In connection with such foreclosure or other conversion,
the Master Servicer shall follow such practices and procedures as it shall deem
necessary or advisable, as shall be normal and usual in its general mortgage
servicing activities and for its own portfolio and as are in accordance with the
requirements of the insurer under any Required Insurance Policy and shall
deliver to the Trustee a liquidation report with respect to the related Mortgage
Loan on the form of report customarily prepared by the Master Servicer. In
particular, the Master Servicer will service each Mortgage Loan in a manner that
preserves the right to proceed against all collateral securing such Mortgage
Loan (e.g., in accordance with any applicable "single action" rule). The Master
Servicer shall not be required to expend its own funds in connection with any
foreclosure or towards the restoration, repair, protection or maintenance of any
property unless it shall determine in its sole discretion that such expenses
will be recoverable to it as Liquidation Expenses either through Liquidation
Proceeds (respecting which it shall have priority for purposes of withdrawals
from the Custodial Account pursuant to Section 3.09(a) hereof) or through
Insurance Proceeds (respecting which it shall have similar priority). 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 proceeds of liquidation of the related Mortgaged
Property, as contemplated in Section 3.09 hereof.

         (b) In the event that any Mortgaged Property becomes an REO Property,
the deed or certificate of sale shall be taken in the name of the Trustee for
the benefit of the Certificateholders, or its nominee, on behalf of the
Certificateholders. 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

                                       53

<PAGE>

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 on such terms and conditions and for such periods as the
Master Servicer deems to be in the best interest of the Master Servicer and the
Certificateholders. Notwithstanding anything herein to the contrary, in the
event that the Trust Fund acquires any REO Property as aforesaid or otherwise in
connection with a default or imminent default on a Mortgage Loan, the Master
Servicer, on behalf of the Trust Fund, shall dispose of such REO Property within
three full years after the taxable year of its acquisition by the Trust Fund for
purposes of Section 860G(a)(8) of the Code (or such shorter period as may be
necessary under applicable state (including any state in which such property is
located) law to maintain the status of any REMIC as a REMIC under applicable
state law and avoid taxes resulting from such property failing to be foreclosure
property under applicable state law) or, at the expense of the Trust Fund,
request, more than 60 days before the day on which such grace period would
otherwise expire, an extension of such grace period unless the Master Servicer
obtains for the Trustee an Opinion of Counsel, addressed to the Trustee and the
Master Servicer, to the effect that the holding by the Trust Fund of such REO
Property subsequent to such period will not result in the imposition of taxes on
"prohibited transactions" as defined in Section 860F of the Code, or cause any
REMIC to fail to qualify as a REMIC under the Code at any time that any
Certificates are outstanding, in which case the Trust Fund may continue to hold
such REO Property (subject to any conditions contained in such Opinion of
Counsel). The Master Servicer shall be entitled to be reimbursed from the
Custodial Account for any costs incurred in obtaining such Opinion of Counsel.
Notwithstanding any other provision of this Agreement, no REO Property acquired
by the Trust Fund shall be rented (or allowed to continue to be rented) or
otherwise used by or on behalf of the Trust Fund in such circumstances or manner
or pursuant to any terms that would (i) cause such REO Property to fail to
qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code or (ii) subject any REMIC to the imposition of any federal income taxes
on the income earned from such REO Property, including any taxes imposed by
reason of Section 860G(c) of the Code, unless the Master Servicer has agreed to
indemnify and hold harmless the Trust Fund with respect to the imposition of any
such taxes.

         (c) 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 on behalf
of the Certificateholders, net of reimbursement to the Master Servicer for
expenses incurred (including any taxes) in connection with such management,
advances made by the Master Servicer pursuant to Sections 3.01, 3.08, 3.10,
3.11, 3.13, 5.04 or 5.05 in connection with the related Mortgage Loan or REO
Property and Liquidation Expenses incurred by the Master Servicer in connection
with the related Mortgage Loan, shall be applied to the payment of principal of
and interest on the related defaulted Mortgage Loans (with interest accruing and
principal amortizing as though such Mortgage Loans were still current) and all
such income shall be deemed, for all purposes in this Agreement, to be payments
on account of principal of and interest on the related Mortgage Notes and shall
be deposited into the Custodial Account.

         (d) Prior to obtaining or causing the Trustee to obtain a deed as a
result of or in lieu of foreclosure, or otherwise acquiring (or causing the
Trustee to acquire) possession of or title to any

                                       54

<PAGE>

Mortgaged Property, if the Master Servicer determines that obtaining a deed or
otherwise acquiring title or possession of such Mortgaged Property would likely
subject the Master Servicer, the Trustee or the Trust Fund to substantial
liability in respect of environmental conditions concerning the Mortgaged
Property, (a) the Master Servicer shall (i) notify the Trustee and the Seller of
such determination and (ii) refrain from obtaining or directing the Trustee to
obtain a deed as a result of or in lieu of foreclosure or otherwise acquiring
title or possession to such Mortgaged Property and (b) the obligations of the
Master Servicer to make advances, including, without limitation, Monthly
Advances, in connection with the Mortgage Loan in question shall cease as of the
date that the Master Servicer makes such determination.

         SECTION 3.14      TRUSTEE TO COOPERATE; RELEASE OF TRUSTEE 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 will be escrowed in a
manner customary for such purposes, and upon notification by the Master Servicer
in the form of 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 have been or
will be so deposited) of a Servicing Officer and a Request for Release of the
Trustee Mortgage File in the form of Exhibit G hereto the Trustee shall promptly
release the related Trustee Mortgage File to the Master Servicer, and the
Trustee shall execute and deliver to the Master Servicer the request for
reconveyance, deed of reconveyance or release, satisfaction or assignment of
mortgage or such instrument releasing the lien of the Mortgage, and, in each
case, such other documents or instruments as may be reasonably required in
connection therewith, as directed by the Master Servicer, together with the
Mortgage Note with written evidence of cancellation thereon. The provisions of
the immediately preceding sentence shall not, in any manner, limit or impair the
right of the Master Servicer to execute and deliver, on behalf of the Trustee,
the Certificateholders or any of them, any and all instruments of satisfaction,
cancellation or assignment, 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. No expenses incurred in connection with any instrument of
satisfaction or deed of reconveyance shall be chargeable to the Certificate
Account but shall be paid by the Master Servicer. From time to time and as shall
be appropriate for the servicing or foreclosure of any Mortgage Loan, including,
without limitation, for such purpose, collection under any policy of flood
insurance, any fidelity bond or errors or omissions policy, or for the purposes
of effecting a partial or total release of any Mortgaged Property from the lien
of the Mortgage or the making of any corrections to the Mortgage Note or the
Mortgage or any of the other documents included in the Trustee Mortgage File,
the Trustee shall, upon request of the Master Servicer and the delivery to the
Trustee of a Request for Release signed by a Servicing Officer, in the form of
Exhibit G hereto, release the Trustee Mortgage File to the Master Servicer. If
the Master Servicer at any time seeks to initiate a foreclosure proceeding in
respect of any Mortgaged Property, the Master Servicer shall deliver to the
Trustee, for signature as appropriate, any court pleadings, requests for
trustee's sale or other documents necessary to effectuate such foreclosure or
any legal action brought to obtain judgment against the Mortgagor on the
Mortgage Note or the Mortgage or to obtain a deficiency judgment or to enforce
any other remedies or rights provided by the Mortgage Note or the Mortgage or
otherwise available at law or in equity, together with a certificate of a
Servicing Officer requesting that such pleadings or documents be executed by the
Trustee. A Servicing Officer shall certify as to the reason such documents or
pleadings are required and that the

                                       55

<PAGE>

execution and delivery thereof by the Trustee will not invalidate the insurance
coverage under any Required Insurance Policy or invalidate or otherwise affect
the lien of the Mortgage except for the termination of such lien upon completion
of the foreclosure.

         SECTION 3.15      DOCUMENTS, RECORDS AND FUNDS IN POSSESSION OF
                           MASTER SERVICER TO BE HELD FOR THE TRUSTEE FOR THE
                           BENEFIT OF THE CERTIFICATEHOLDERS.
                           --------------------------------------------------

         Notwithstanding any other provisions of this Agreement, the Master
Servicer shall transmit to the Trustee to the extent required by this Agreement
all documents and instruments coming into the possession of the Master Servicer
from time to time and shall account fully to the Trustee for the benefit of the
Certificateholders for any funds received by the Master Servicer or which
otherwise are collected by the Master Servicer as Liquidation Proceeds or
Insurance Proceeds in respect of any Mortgage Loan. All Master Servicer Mortgage
Files or Trustee Mortgage Files and funds collected or held by, or under the
control of, the Master Servicer in respect of any Mortgage Loans, whether from
the collection of principal and interest payments or from Liquidation Proceeds
or Insurance Proceeds, including but not limited to, any funds on deposit in the
Custodial Account, shall be held by the Master Servicer for and on behalf of the
Trustee for the benefit of the Certificateholders 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 Master Servicer Mortgage File or Trustee Mortgage File or
any funds that are deposited in the Custodial Account or 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 setoff against any Master Servicer
Mortgage File or Trustee 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
subject to the terms of this Agreement.

         SECTION 3.16      SERVICING COMPENSATION; COMPENSATING INTEREST.
                           ---------------------------------------------

         (a) As compensation for its activities hereunder, the Master Servicer
shall be entitled to (i) retain from the Monthly Payments the Servicing Fee for
each Mortgage Loan and (ii) retain from the Custodial Account or withdraw from
the Custodial Account the amounts specified in subclause (i) of Section 3.09(a)
hereof as payable to it.

         (b) Additional servicing compensation in the form of prepayment
penalties, fees or premiums, assumption fees, modification fees, late payment
charges or otherwise or any excess interest charges payable by the Mortgagor by
virtue of any default or other non-compliance by the Mortgagor with the terms of
the Mortgage or any other instrument or document executed in connection
therewith or otherwise shall be retained by the Master Servicer to the extent
not required to be deposited in the Custodial Account pursuant to Section 3.07
hereof. To the extent provided in this Agreement, the Master Servicer shall be
required to pay all expenses incurred by it in connection with its servicing
activities hereunder (including the payment of premiums for Primary Mortgage
Insurance Policies, to the extent such premiums are not required to be paid or
have not

                                       56

<PAGE>

been paid by the related Mortgagor or the related Sub-Servicer, payment of any
premiums for hazard insurance, as required by Section 3.11 hereof and
maintenance of the other forms of insurance coverage required by Section 3.11
hereof, the payment of servicing compensation to any Sub-Servicers pursuant to
any Sub-Servicing Agreement and the payment of the expenses of the Trustee to
the extent provided in Section 9.05), and shall not be entitled to reimbursement
therefor except as specifically provided in Sections 3.09, 3.13, 4.01 and 5.05
hereof.

         (c) Notwithstanding any other provision herein, the amount of servicing
compensation that the Master Servicer shall be entitled to receive for its
activities hereunder for the period ending on each Distribution Date shall be
reduced (but not below zero) by an amount equal to Compensating Interest (if
any) for such Distribution Date. The Master Servicer shall, within one Business
Day of each Distribution Date, remit to the Trustee (but without duplication of
any Compensating Interest taken into account in any Monthly Advance made on such
date) the Compensating Interest due on such Distribution Date.

         (d) In addition to the foregoing, in consideration for entering into
this Agreement, the Mortgage Loan Seller assigns all of its right, title and
interest to the Retained Interest to the Master Servicer. The Master Servicer,
so long as it is acting in such capacity hereunder, shall be entitled to retain
the Retained Interest as servicing compensation on a daily basis from
collections on the Mortgage Loans, and any successor to the Master Servicer
hereunder shall automatically succeed to such right.

         SECTION 3.17      REPORTS TO THE SELLER; ACCOUNT STATEMENTS.
                           -----------------------------------------

         Within five Business Days following each Distribution Date, the Master
Servicer shall deliver to the Trustee a statement setting forth the status of
the Custodial Account, if any, as of the close of business on such Distribution
Date showing, for the period covered by such statement, the aggregate of
deposits in or withdrawals from the Custodial Account, if any, for each category
of deposit specified in Section 3.07 hereof and each category of withdrawal

Certificate stating, as to each signer thereof, that (a) a review of the
activities of the Master Servicer during the year ended on the preceding
December 31 and of the performance of the Master Servicer under this Agreement
has been made under such officer's supervision, (b) to the best of such
officer's knowledge, based on such review, the Master Servicer has fulfilled all
its obligations under this Agreement in all material respects throughout 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, (c) a Servicing Officer has conducted an examination of the activities
of each Sub-Servicer during the immediately preceding year and its performance
under any Sub-Servicing Agreement, and (d) to the best of such Servicing
Officer's knowledge, based on such examination, each Sub-Servicer has performed
and fulfilled its duties, responsibilities and obligations under such
Sub-Servicing Agreement in all material respects throughout such year, or if
there has been a default in the performance or fulfillment of any such

                                       57

<PAGE>

duties, responsibilities or obligations, specifying each such default known to

         On or before March 31 of each year, beginning with the first March 31
that occurs at least eleven months after the Cut-off Date, the Master Servicer,
at its expense, shall cause a firm of independent public accountants that is a
member of the American Institute of Certified Public Accountants to furnish a
statement to the Seller and the Trustee for the benefit of the
Certificateholders to the effect that such firm has examined certain documents
substantially similar to this Agreement and records relating to the servicing of
mortgage loans serviced by the Master Servicer or any successor master servicer
that are substantially similar to the Mortgage Loans and that, on the basis of
an examination conducted substantially in compliance with the Uniform Single
Audit Program for Mortgage Bankers or the Audit Program for Mortgages serviced
for Freddie Mac, such servicing has been conducted in compliance with such
agreements except for such significant exceptions or errors in records that, in
the opinion of such firm, the Uniform Single Audit Program for Mortgage Bankers
or the Audit Program for Mortgages serviced for Freddie Mac requires it to
report. In rendering such statement such firm may rely, as to matters relating
to direct servicing of Mortgage Loans by Sub-Servicers, if any, upon comparable
statements for examinations conducted substantially in compliance with the
Uniform Single Audit Program for Mortgage Bankers or the Audit Program for
Mortgages serviced for Freddie Mac (rendered within one year of such statement)
of independent public accounts with respect to the related Sub-Servicer. The
Master Servicer shall forward a copy of each such report to the Rating Agencies.

         SECTION 3.20      REPORTS TO TRUSTEE.
                           ------------------

Section 4.03(a). The Trustee may conclusively rely on information provided by
the Master Servicer and shall have no obligation to recompute, recalculate, or
verify the accuracy of such information.

                           -------------------

         (a) The Trustee shall establish, prior to the Closing Date, and shall
maintain, in the name of the Trustee on behalf of the Holders of interests in
the Trust Fund, the Certificate Account, which shall be an Eligible Account,
into which the Trustee upon receipt from the Master Servicer shall deposit all
payments remitted by the Master Servicer and any amounts required to be remitted
by the Seller pursuant to the terms hereof. All distributions to be made from
time to time to Holders of interests in the Trust Fund out of funds in the
Certificate Account shall be made by or on behalf of the Trustee. The
Certificate Account shall relate solely to the Certificates issued hereunder and
funds in the Certificate Account shall be held separate and apart from and shall
not be commingled with any monies including, without limitation, other monies of
the Trustee held under this Agreement. The Trustee will give notice to the
Master Servicer and the Seller of the location of the Certificate Account and of
any change thereof, prior to the use thereof. Funds held in the Certificate
Account and delivered to the Trustee earlier than one Business Day prior to the
next Distribution Date (or delivered on such Distribution Date within time
frames to be agreed upon between the Master Servicer and the Trustee) shall be
invested by the Trustee in Eligible Investments as directed by the Master
Servicer for the benefit of the Master Servicer or shall remain uninvested. The
Trustee shall cause each such Eligible Investment to be Delivered to it or its
nominee (including a securities intermediary). All income and gain net of any
losses realized from any such investment shall be for the benefit of the Master
Servicer and shall be subject to withdrawal at the Master Servicer's direction
from time to time. The amount of any losses net of any gains incurred by the
Master Servicer in respect of any such investments shall be deposited in the
Certificate Account out of the Master Servicer's own funds immediately as
realized.

         (b) The Trustee shall make, to the extent required or authorized
hereunder, withdrawals from the Certificate Account for the following purposes:

                  (i) as directed by the Master Servicer, to withdraw any amount
         deposited in the Certificate Account and not required to be deposited
         therein;

                  (ii) to reimburse the Master Servicer for any unreimbursed
         Nonrecoverable Advance;

                  (iii) to make required distributions pursuant to Section 5.02;
         and

                  (iv) to pay to the Seller or the Master Servicer any amount to
         which it is entitled pursuant to Section 7.03.

                       DISTRIBUTIONS TO CERTIFICATEHOLDERS

         SECTION 5.01      DISTRIBUTIONS GENERALLY.
                           -----------------------

         (a) Subject to Section 10.01 respecting the final distribution on the
Certificates, on each Distribution Date the Trustee shall make distributions in
accordance with this Article V. Such distributions shall be made by check mailed
to each Certificateholder's address as it appears on the Certificate Register of
the Certificate Registrar (which shall initially be the Trustee) or, upon
written request made to the Trustee at least five Business Days prior to the
related Record Date by any Certificateholder owning an aggregate initial Current
Principal Amount of at least $1,000,000, or, in the case of a Class R
Certificate, a Percentage Interest of 100%, by wire transfer in immediately
available funds to an account specified in the request and at the expense of
such Certificateholder; provided, however, that the final distribution in
respect of any Certificate shall be made only upon presentation and surrender of
such Certificate at the Corporate Trust Office. Wire transfers will be made at
the expense of the Holder requesting such wire transfer by deducting a wire
transfer fee from the related distribution. Notwithstanding such final payment
of principal of any of the Certificates, the Residual Certificate will remain
outstanding until the termination of the REMIC and the payment in full of all
other amounts due with respect to such Certificates and at such time such final
payment in retirement of any Residual Certificate will be made only upon
presentation and surrender of such Certificate at the Corporate Trust Office or
at the office of the Trustee's New York presenting agent. If any payment
required to be made on the Certificates is to be made on a day that is not a
Business Day, then such payment will be made on the next succeeding Business
Day.

         (b) All distributions or allocations made with respect to
Certificateholders within each Class on each Distribution Date shall be
allocated among the outstanding Certificates in such Class equally in proportion
to their respective initial Current Principal Amounts (or Percentage Interests).

         SECTION 5.02      DISTRIBUTIONS FROM THE CERTIFICATE ACCOUNT.
                           ------------------------------------------

         (a) On each Distribution Date the Trustee shall withdraw from the
Certificate Account the Total Distribution Amount for such date, shall allocate
such amount to the interests issued in respect of the Trust Fund and shall
distribute such amount as specified in this Section.

         (b) On each Distribution Date, the Trustee shall distribute the
Interest Remittance Amount for such date in the following order of priority:

                  (i) to the Trustee, the Trustee Fee for such Distribution
         Date; and

                  (ii) to the Senior Certificates, pro rata, Accrued Certificate
         Interest for such Class and such Distribution Date, plus any unpaid
         Accrued Certificate Interest remaining unpaid from any prior
         Distribution Date;

                                       63

         Distribution Date;

                  (iv) to the Class M-2 Certificates, Accrued Certificate

         Distribution Date;

                  (v) to the Class M-3 Certificates, Accrued Certificate
         Interest for such Class and such Distribution Date, plus any unpaid
         Accrued Certificate Interest remaining unpaid from any prior
         Distribution Date;

                  (vi) to the Class B-1 Certificates, Accrued Certificate
         Interest for such Class and such Distribution Date, plus any unpaid
         Accrued Certificate Interest remaining unpaid from any prior
         Distribution Date;

                  (vii) to the Class B-2 Certificates, Accrued Certificate
         Interest for such Class and such Distribution Date, plus any unpaid
         Accrued Certificate Interest remaining unpaid from any prior
         Distribution Date;

                  (viii) to the Class B-3 Certificates, Accrued Certificate
         Interest for such Class and such Distribution Date, plus any unpaid
         Accrued Certificate Interest remaining unpaid from any prior
         Distribution Date; and

                  (ix) any remaining Interest Remittance Amount to the Class R
         Certificates.

         (c) On each Distribution Date, the Trustee shall distribute the
Principal Remittance Amount for such date as follows:

                  (i) to the holders of the Class R Certificates and Class A
         Certificates, in that order, to the extent of the Principal Remittance
         Amount, the Senior Principal Distribution Amount, in reduction of the
         Current Principal Amounts thereof, until the Current Principal Amounts
         thereof have been reduced to zero;

                  (ii) to the holders of the Class M-1 Certificates, to the
         extent of the portion of the Principal Remittance Amount remaining
         after the distribution in clause (i) above, the Class M-1 Principal
         Distribution Amount, in reduction of the Current Principal Amount
         thereof, until the Current Principal Amount thereof has been reduced to
         zero;

                  (iii) to the holders of the Class M-2 Certificates, to the
         extent of the portion of the Principal Remittance Amount remaining
         after distributions in clauses (i) and (ii) above, the Class M-2
         Principal Distribution Amount, in reduction of the Current Principal
         Amount thereof, until the Current Principal Amount thereof has been
         reduced to zero;

                  (iv) to the holders of the Class M-3 Certificates, to the
         extent of the portion of the Principal Remittance Amount remaining
         after distributions in clauses (i) through (iii) above,

                                       64

<PAGE>

         the Class M-3 Principal Distribution Amount, in reduction of the
         Current Principal Amount thereof, until the Current Principal Amount
         thereof has been reduced to zero;

                  (v) to the holders of the Class B-1 Certificates, to the
         extent of the portion of the Principal Remittance Amount remaining
         after the distributions in clauses (i) through (iv) above, the Class
         B-1 Principal Distribution Amount, in reduction of the Current
         Principal Amount thereof, until the Current Principal Amount thereof
         has been reduced to zero;

                  (vi) to the holders of the Class B-2 Certificates, to the
         extent of the portion of the Principal Remittance Amount remaining
         after the distributions in clauses (i) through (v) above, the Class B-2
         Principal Distribution Amount, in reduction of the Current Principal
         Amount thereof, until the Current Principal Amount thereof has been
         reduced to zero; and

                  (vii) to the holders of the Class B-2, Class B-1, Class M-3,
         Class M-2, Class M-1, Class A and Class B-3 Certificates, in that
         order, the Principal Remittance Amount remaining after the
         distributions in clauses (i) through (vi) above, in reduction of the
         Current Principal Amounts thereof, until the Current Principal Amounts
         thereof have been reduced to zero; and

                  (viii) to the holders of the Class R Certificates.

         Notwithstanding the foregoing, on any Distribution Date on which the
Class Principal Amount of each Class of Certificates having a higher priority of
distribution has been reduced to zero, any remaining Principal Remittance Amount
will be distributed to the remaining Certificates in the order of priority set
forth above until the Class Principal Amount of each such Class has been reduced
to zero.

         (d) On or prior to each Determination Date, the Master Servicer shall
determine the amount of any Deferred Interest in respect of each Mortgage Loan
that occurred during the immediately preceding calendar month and provide such
information to the Trustee pursuant to Section 3.20. With respect to any
Distribution Date, the aggregate amount of Deferred Interest, if any, that is
added to the Scheduled Principal Balance of the Mortgage Loans on the Due Date
occurring in the month in which such Distribution Date occurs will be added to
the Current Principal Amounts of the Certificates 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 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
Pass-Through Rate.

         SECTION 5.03      ALLOCATION OF LOSSES.
                           --------------------

         (a) On each Distribution Date, Realized Losses will be allocated to the
Class A, Class M-1, Class M-2, Class M-3, Class B-1, Class B-2 and Class B-3
Certificates, in the following order of priority:

                                       65

<PAGE>

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

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

                  (iii) to the Class B-1 Certificates, until the Current
         Principal Amount thereof has been reduced to zero;

                  (iv) to the Class M-3 Certificates, until the Current
         Principal Amount thereof has been reduced to zero;

                  (v) to the Class M-2 Certificates, until the Current Principal
         Amount thereof has been reduced to zero;

                  (vi) to the Class M-1 Certificates, until the Current
         Principal Amount thereof has been reduced to zero; and

                  (vii) to the Class A Certificates, until the Current Principal
         Amount thereof has been reduced to zero.

         (b) Notwithstanding the foregoing, 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").

         (c) 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.

         (d) 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.

         (e) On each Distribution Date, the Trustee shall determine the
Subordinate Certificate Writedown Amount based solely on the information
received from the Master Servicer. Any such Subordinate Certificate Writedown
Amount shall effect a corresponding reduction in the Current Principal Amount of
the Current Principal Amounts of the Subordinate Certificates, in the reverse
order of their numerical Class designations, and then the Senior Certificates,
pro rata based on their respective Current Principal Amounts, which reduction
shall occur on such Distribution Date after giving effect to distributions made
on such Distribution Date.

         SECTION 5.04      MONTHLY ADVANCES BY THE MASTER SERVICER.
                           ---------------------------------------

         (a) Subject to the conditions of this Article V, the Master Servicer,
as required below, on each Master Servicer Advance Date shall make an advance (a
"Monthly Advance") to the Certificate Account, in the amount, if any, of the
aggregate Monthly Payments less Net Prepayment Interest Shortfalls and Relief
Act Shortfalls, after adjustment of the interest portion of each such Monthly
Payment to the Net Mortgage Rate, on the Mortgage Loans that were due on the Due
Date but that were not received and remitted to the Certificate Account on or
prior to such Master Servicer Advance Date. The Master Servicer shall be
obligated to make any such Monthly Advance only to the extent that such advance,
in the good faith judgment of the Master Servicer, will not be a Nonrecoverable
Advance.

         (b) On the Determination Date immediately preceding the related
Distribution Date, the Master Servicer shall determine whether and to what
extent any Mortgagor has failed to make any Monthly Payment due on the Due Date
and whether such deficiencies, if advanced by the Master Servicer, would be a
Nonrecoverable Advance. If the Master Servicer shall have determined that it is
not obligated to make the entire Monthly Advance because all or a lesser portion
of such Monthly Advance would not be recoverable by the Master Servicer from
related Insurance Proceeds or Liquidation Proceeds (net of Liquidation
Expenses), the Master Servicer shall deliver to the Trustee, not less than one
Business Day after the related Determination Date, for the benefit of the
Certificateholders, a certificate of a Servicing Officer setting forth the
reasons for such determination.

         (c) In lieu of making all or a portion of any Monthly Advance, the
Master Servicer may cause to be made an appropriate entry in its records
relating to the Custodial Account that funds in such account, including but not
limited to any amounts received in respect of scheduled principal and interest
on any Mortgage due after the related Due Period, in excess of the Total
Distribution Amount (less the amount of such Monthly Advance) for the related
Distribution Date have been used by the Master Servicer in discharge of its
obligation to make any such Monthly Advance. Any funds so applied shall be
replaced by the Master Servicer by deposit, in the manner set forth above, in
the Custodial Account no later than the next Master Servicer Advance Date to the
extent that funds in the Custodial Account on such date are less than the
amounts required to be distributed on the related Distribution Date. The Master
Servicer shall be entitled to be reimbursed from the Custodial Account and the
Certificate Account for all Monthly Advances of its own funds made pursuant to
this Section as provided in Section 3.09 and 4.01.

         SECTION 5.05      ADVANCES FOR ATTORNEYS' FEES.
                           ----------------------------

         The Master Servicer shall make advances from time to time for
attorneys' fees and court costs incurred, or which reasonably can be expected to
be incurred, for the foreclosure of any Mortgage Loan or for any transaction in
which the Trustee for the benefit of the Certificateholders is expected to
receive a deed-in-lieu of foreclosure, unless the Master Servicer has made a
good faith determination that such advances would be Nonrecoverable Advances. If
the Master Servicer shall make a good faith determination that such advances
would not be so recoverable, the Master Servicer shall promptly deliver to the
Trustee a Certificate of a Servicing Officer setting forth the reasons for

                                       67

<PAGE>

such determination. The Master Servicer shall be entitled to reimbursement for
any such advance as provided in Section 3.09 hereof.

         SECTION 5.06      NONRECOVERABLE ADVANCES.
                           -----------------------

         The determination by the Master Servicer that it has made a
Nonrecoverable Advance shall be evidenced by a certificate of a Servicing
Officer promptly delivered to the Trustee setting forth the reasons for such
determination. Following the Trustee's receipt of such certificate, the Master
Servicer shall be entitled to reimbursement for such Nonrecoverable Advance as
provided in Section 3.09 and 4.01 hereof.

         SECTION 5.07      ADVANCE PROCEDURES.
                           ------------------

         (a) If, on any Determination Date, the Master Servicer determines to
make a Monthly Advance in accordance with Section 5.04, it shall make such
Monthly Advance on or before noon, New York time, on the Business Day prior to
the related Distribution Date (the "Master Servicer Advance Date"). The Master
Servicer shall notify the Trustee of the aggregate amount of Monthly Advances
for a Distribution Date on or before three Business Days prior to such
Distribution Date. Any such Monthly Advance shall be included with the
distribution on the related Distribution Date pursuant to Section 5.02.

         (b) In the event that the Master Servicer fails to make a Monthly
Advance required to be made pursuant to Section 5.04 on or before the close of
business, on the Master Servicer Advance Date, the Trustee shall on or before 12
noon, New York time on the next Business Day provide notice to the Master
Servicer, by telephone and by writing (which may be by telecopy) of such failure
and the amount of such failure and that continuance of such failure for a period
of one Business Day thereafter will be an Event of Default.

         SECTION 6.01      THE CERTIFICATES.
                           ----------------

         (a) The Certificates shall be in substantially the forms set forth in
Exhibits A, B, C and D hereto, with such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Agreement or as may in the reasonable judgment of the Trustee or the Seller be
necessary, appropriate or convenient to comply, or facilitate compliance, with
applicable laws, and may have such letters, numbers or other marks of
identification and such legends or endorsements placed thereon as may be
required to comply with the rules of any securities exchange on which any of the
Certificates may be listed, or as may, consistently herewith, be determined by
the officers executing such Certificates, as evidenced by their execution
thereof.

         (b) The Definitive Certificates shall be printed, typewritten,
lithographed or engraved or produced by any combination of these methods or may
be produced in any other manner permitted by the rules of any securities
exchange on which any of the Certificates may be listed, all as determined by
the officers executing such Certificates, as evidenced by their execution
thereof.

         (c) Each Class of Book-Entry Certificates will be evidenced by one or
more certificates, beneficial ownership of which will be held in the dollar
denominations in Current Principal Amount specified in this paragraph. Each
Class of Class A Certificates will be issued in minimum denominations of a
$1,000 Current Principal Amount and integral multiples of $1 in excess thereof.
Each Class of Class M Certificates will be issued in minimum denominations of a
$25,000 Current Principal Amount and integral multiples of $1 in excess thereof.
Each Class of Class B Certificates will be maintained in definitive, fully
registered form in minimum denominations of $100,000 Current Principal Amount
and integral multiples of $1 in excess thereof. The Class R Certificates will be
issued as a single Certificate and maintained in definitive, fully registered
form in a minimum denomination equal to 100% of the Percentage Interest of such
Class. One Certificate of each Class of Certificates other than the Class R
Certificates may be issued in any denomination in excess of the minimum
denomination.

         (d) The Certificates shall be executed by manual or facsimile signature
on behalf of the Trust Fund by the Trustee by a Responsible Officer.
Certificates bearing the manual or facsimile signatures of individuals who were,
at the time when such signatures were affixed, authorized to sign on behalf of
the Trustee shall bind the Trust Fund, notwithstanding that such individuals or
any of them have ceased to be so authorized prior to the authentication and
delivery of such Certificates or did not hold such offices at the date of such
Certificate. 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 executed by the Trustee by manual signature, and
such certificate of authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication.

                           CERTIFICATES.
                           ----------------------------------------

         (a) The Trustee shall maintain, or cause to be maintained, 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. Upon surrender for
registration of transfer of any Certificate, the Trustee shall execute,

         (b) At the option of a Certificateholder, Certificates (other than

exchanged for other Certificates of authorized denominations and the same
aggregate interest in the Trust Fund and of the same Class, upon surrender of
the Certificates to be exchanged at the office or agency of the Trustee in the
City of New York at 123 Washington Street, New York, New York 10006 where
Certificates may be surrendered for registration of transfer or exchange. The
Trustee will give prompt written notice to Certificateholders of any change in
the location of the any such office or agency. The Certificate Register will be
kept in Santa Ana, California at the offices of the Trustee located at the
Corporate Trust Office and may be kept in an electronic form capable of printing
out a hard copy of the Certificate Register. 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 registration of transfer
or exchange shall be accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder thereof or his attorney
duly authorized in writing.

         (c) All Certificates surrendered for registration of transfer and
exchange shall be canceled and subsequently destroyed by the Trustee in
accordance with the Trustee's customary procedures.

         (d) By acceptance of a Restricted 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 thereon and
agrees that it will transfer such a Certificate only as provided herein. With
respect to the transfer and registration of transfer of a Restricted Certificate
to a transferee that takes delivery in the form of a Definitive Certificate, the
Trustee shall register the transfer of a Restricted Certificate if the requested
transfer is (x) to the Seller or the Placement Agents, an affiliate (as defined
in Rule 405 under the 1933 Act) of the Seller or the Placement Agents or (y)
being made to a "qualified institutional buyer" (a "QIB") as defined in Rule
144A under the 1933 Act by a transferor that has provided the Trustee with a
certificate in the form of Exhibit H hereto.

         (e) No transfer of an ERISA-Restricted Certificate in the form of a
Definitive Certificate shall be made to any Person unless the Trustee has
received (A) in the case of a Class B-1, Class B-2 or Class B-3 Certificate, a
certificate substantially in the form of Exhibit I hereto from such transferee
or (B) an Opinion of Counsel satisfactory to the Trustee, the Master Servicer
and the Seller to the effect that the purchase and holding of such a Certificate
will not constitute or result in the assets of the Trust Fund being deemed to be
"plan assets" subject to the prohibited transactions provisions of ERISA or
Section 4975 of the Code and will not subject the Trustee, the Master Servicer
or the Seller to any obligation in addition to those undertaken in the
Agreement; provided,

                                       70

<PAGE>

however, that the Trustee will not require such certificate or opinion in the
event that, as a result of a change of law or otherwise, counsel satisfactory to
the Trustee has rendered an opinion to the effect that the purchase and holding
of an ERISA-Restricted Certificate by a Plan or a Person that is purchasing or
holding such a Certificate with the assets of a Plan will not constitute or
result in a prohibited transaction under ERISA or Section 4975 of the Code. The
preparation and delivery of the certificate and opinions referred to above shall
not be an expense of the Trust Fund, the Trustee or the Seller. Notwithstanding
the foregoing, no opinion or certificate shall be required for the initial
issuance of the ERISA-Restricted Certificates.

         (f) As a condition of the registration of transfer or exchange of any
Certificate, the Trustee may require the certified taxpayer identification
number of the owner of the Certificate and the payment of a sum sufficient to
cover any tax or other governmental charge imposed in connection therewith;
provided, however, that the Trustee shall have no obligation to require such
payment or to determine whether or not any such tax or charge may be applicable.
No service charge shall be made to the Certificateholder for any registration,
transfer or exchange of Certificate.

         (g) Notwithstanding anything to the contrary contained herein, no
Residual Certificate may be owned, pledged or transferred, directly or
indirectly, by or to (i) a Disqualified Organization or (ii) an individual,
corporation or partnership or other person unless such person (A) is not a
Non-U.S. Person or (B) is a Non-U.S. Person that holds a Residual Certificate in
connection with the conduct of a trade or business within the United States and
has furnished the transferor and the Trustee with an effective Internal Revenue
Service Form 4224, Form W-8ECI or successor form at the time and in the manner
required by the Code (any such person who is not covered by clause (A) or (B)
above is referred to herein as a "Non-permitted Foreign Holder").

         Prior to and as a condition of the registration of any transfer, sale
or other disposition of a Residual Certificate, the proposed transferee shall
deliver to the Trustee an affidavit in substantially the form attached hereto as
Exhibit J-1 representing and warranting, among other things, that such
transferee is neither a Disqualified Organization, an agent or nominee acting on
behalf of a Disqualified Organization, nor a Non-permitted Foreign Holder (any
such transferee, a "Permitted Transferee") and the proposed transferor shall
deliver to the Trustee an affidavit in substantially the form attached hereto as
Exhibit J-2. In addition, the Trustee may (but shall have no obligation to)
require, prior to and as a condition of any such transfer, the delivery by the
proposed transferee of an Opinion of Counsel, addressed to the Seller and the
Trustee satisfactory in form and substance to the Seller, that such proposed
transferee or, if the proposed transferee is an agent or nominee, the proposed
beneficial owner, is not a Disqualified Organization, agent or nominee thereof,
or Non-permitted Foreign Holder. Notwithstanding the registration in the
Certificate Register of any transfer, sale, or other disposition of a Residual
Certificate to a Disqualified Organization, an agent or nominee thereof, or
Non-permitted Foreign Holder, such registration shall be deemed to be of no
legal force or effect whatsoever and such Disqualified Organization, agent or
nominee thereof, or Non-permitted Foreign Holder shall not be deemed to be a
Certificateholder for any purpose hereunder, including, but not limited to, the
receipt of distributions on such Residual Certificate. The Trustee shall not be
under any liability to any person for any registration or transfer of a Residual
Certificate to a Disqualified Organization, agent or nominee thereof, or
Non-permitted Foreign Holder or for the maturity of any payments due on such
Residual Certificate to the Holder thereof or for taking any other action with
respect to such Holder under the provisions of the Agreement, so

                                       71

<PAGE>

long as the transfer was effected in accordance with this Section 6.02(g),
unless the Trustee shall have actual knowledge at the time of such transfer or
the time of such payment or other action that the transferee is a Disqualified
Organization, agent or nominee thereof, or Non-permitted Foreign Holder. The
Trustee shall be entitled to recover from any Holder of a Residual Certificate
that was a Disqualified Organization, agent or nominee thereof, or Non-permitted
Foreign Holder at the time it became a Holder or any subsequent time it became a
Disqualified Organization, agent or nominee thereof, or Non-permitted Foreign
Holder, all payments made on such Residual Certificate at and after either such
times (and all costs and expenses, including but not limited to attorneys' fees,
incurred in connection therewith). Any payment (not including any such costs and
expenses) so recovered by the Trustee shall be paid and delivered to the last
preceding Holder of such Residual Certificate.

         If any purported transferee shall become a registered Holder of a
Residual Certificate in violation of the provisions of this Section 6.02(g),
then upon receipt of written notice to the Trustee that the registration of
transfer of such Residual Certificate was not in fact permitted by this Section
6.02(g), the last preceding Permitted Transferee shall be restored to all rights
as Holder thereof retroactive to the date of such registration of transfer of
such Residual Certificate. The Trustee shall be under no liability to any Person
for any registration of transfer of a Residual Certificate that is in fact not
permitted by this Section 6.02(g), for making any payment due on such
Certificate to the registered Holder thereof or for taking any other action with
respect to such Holder under the provisions of this Agreement so long as the
transfer was registered upon receipt of the affidavit described in the preceding
paragraph of this Section 6.02(g).

         (h) Each Holder of a Residual Certificate, by such Holder's acceptance
thereof, shall be deemed for all purposes to have consented to the provisions of
this section.

         SECTION 6.03      MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.
                           -------------------------------------------------

         If (a) 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 (b) there is delivered to the Master Servicer and the
Trustee such security or indemnity as may be required by them to save each of
them 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 like
tenor and interest in the Trust Fund. In connection with the issuance of any new
Certificate under this Section 6.03, 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 replacement Certificate issued pursuant to
this Section 6.03 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 6.04      PERSONS DEEMED OWNERS.

         Subject to the provisions of Section 6.07 with respect to any
Book-Entry Certificates, prior to due presentation of a Certificate for
registration of transfer, the Master Servicer, the Trustee, and any agent of the
Master Servicer 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 as provided in this Agreement and for all other purposes
whatsoever, and neither the Master Servicer, the Trustee nor any agent of the
Master Servicer or the Trustee shall be affected by any notice to the contrary.

         SECTION 6.05      ACCESS TO LIST OF CERTIFICATEHOLDERS' NAMES AND
                           ADDRESSES.
                           -----------------------------------------------

         (a) If three or more Certificateholders (i) request in writing from the
Trustee a list of the names and addresses of Certificateholders, (ii) state that
such Certificateholders desire to communicate with other Certificateholders with
respect to their rights under this Agreement or under the Certificates and (iii)
provide a copy of the communication which such Certificateholders propose to
transmit, then the Trustee shall, within ten Business Days after the receipt of
such request, afford such Certificateholders access during normal business hours
to a current list of the Certificateholders. The expense of providing any such
information requested by a Certificateholder shall be borne by the
Certificateholders requesting such information and shall not be borne by the
Trustee. Every Certificateholder, by receiving and holding a Certificate, agrees
that the Trustee shall not be held accountable by reason of the disclosure of
any such information as to the list of the Certificateholders hereunder,
regardless of the source from which such information was derived.

         (b) The Master Servicer, so long as it is the Master Servicer
hereunder, shall have unlimited access to a list of the names and addresses of
the Certificateholders which list shall be provided by the Trustee promptly upon
the request of the Master Servicer.

         SECTION 6.06      MAINTENANCE OF OFFICE OR AGENCY.
                           -------------------------------

         The Trustee will maintain or cause to be maintained at its expense an
office or offices or agency or agencies where Certificates may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Trustee in respect of the Certificates and this Agreement may be
served. The Trustee initially designates its office at 123 Washington Street,
New York, New York 10006 as its office for such purpose. The Trustee will give
prompt written notice to the Certificateholders of any change in the location of
any such office or agency.

         SECTION 6.07      BOOK-ENTRY CERTIFICATES.
                           -----------------------

         (a) Each class of Book-Entry Certificates, upon original issuance,
shall be issued in the form of one or more typewritten Certificates representing
the Book-Entry Certificates, to be delivered to DTC, the initial Clearing
Agency, by, or on behalf of, the Seller. The Book-Entry Certificates shall
initially be registered on the Certificate Register in the name of the nominee
of DTC, and no Beneficial Holder will receive a definitive certificate
representing such Beneficial Holder's interest in the Book-Entry Certificates,
except as provided in Section 6.09. Unless and until Definitive Certificates
have been issued to the Beneficial Holders pursuant to Section 6.09:

                                       73

<PAGE>

                  (i) the provisions of this Section 6.07 shall be in full force
         and effect with respect to such Book-Entry Certificates;

                  (ii) the Seller and the Trustee may deal with the Clearing
         Agency for all purposes with respect to such Book-Entry Certificates
         (including the making of distributions on such Certificates) as the
         sole Holder of such Certificates;

                  (iii) to the extent that the provisions of this Section 6.07
         conflict with any other provisions of this Agreement, the provisions of
         this Section 6.07 shall control;

                  (iv) the rights of the Beneficial Holders of such Book-Entry
         Certificates shall be exercised only through the Clearing Agency and
         the Participants and shall be limited to those established by law and
         agreements between such Beneficial Holders and the Clearing Agency
         and/or the Participants. Pursuant to the Depository Agreement, unless
         and until Definitive Certificates are issued pursuant to Section 6.09,
         the initial Clearing Agency will make book-entry transfers among the
         Participants and receive and transmit distributions of principal and
         interest on the related Certificates to such Participants; and

                  (v) any transferee of a beneficial interest in a Restricted
         Certificate in the form of a Book-Entry Certificate will be deemed to
         have made one of the representations set forth in Exhibit H hereto and
         if any purported transferee shall become a registered Holder of a
         Restricted Certificate in violation of such representations, then the
         last preceding qualified transferee shall be deemed restored to all
         rights as Holder thereof retroactive to the date of such transfer of
         such Restricted Certificate.

         (b) For purposes of any provision of this Agreement requiring or
permitting actions with the consent of, or at the direction of, Holders of each
Class of such Book-Entry Certificates evidencing a specified percentage of the
aggregate unpaid principal amount of such Certificates, such direction or
consent may be given by the Clearing Agency at the direction of Beneficial
Holders owning such Certificates evidencing the requisite percentage of
principal amount of such Certificates. The Clearing Agency may take conflicting
actions with respect to each Class of such Book-Entry Certificates to the extent
that such actions are taken on behalf of the Beneficial Holders.

         SECTION 6.08      NOTICES TO CLEARING AGENCY.
                           --------------------------

         Whenever notice or other communication to the Holders of each Class of
Book-Entry Certificates is required under this Agreement, unless and until
Definitive Certificates shall have been issued to the related Certificateholders
pursuant to Section 6.09, the Trustee shall give all such notices and
communications specified herein to be given to Holders of each Class of the
Book-Entry Certificates to the Clearing Agency which shall give such notices and
communications to the related Participants in accordance with its applicable
rules, regulations and procedures.

         SECTION 6.09      DEFINITIVE CERTIFICATES.
                           -----------------------

         If (a) the Seller advises the Trustee in writing that the Clearing
Agency is no longer willing or able to properly discharge its responsibilities
under the Depository Agreement with respect to the Certificates and the Trustee
or the Seller is unable to locate a qualified successor, (b) the Seller, at its
option, advises the Trustee in writing that it elects to terminate the
book-entry system with respect to any or all of the Book-Entry Certificates
through the Clearing Agency or (c) after the occurrence of an Event of Default,
Holders of each Class of Book-Entry Certificates evidencing not less than
66-2/3% of the aggregate Current Principal Amount of such Class of the
Book-Entry Certificates advise the Trustee in writing that the continuation of a
book-entry system with respect to the such Certificates through the Clearing
Agency is no longer in the best interests of the Holders of such Certificates
with respect to such Class of the Book-Entry Certificates, the Trustee shall
notify all Holders of such Certificates of the occurrence of any such event and
the availability of Definitive Certificates. Upon surrender to the Trustee of
the such Certificates by the Clearing Agency, accompanied by registration
instructions from the Clearing Agency for registration, the Trustee shall
authenticate and deliver 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.
Upon the issuance of Definitive Certificates all references herein to
obligations imposed upon or to be performed by the Clearing Agency shall be
deemed to be imposed upon and performed by the Trustee, to the extent applicable
with respect to such Definitive Certificates, and the Trustee shall recognize
the Holders of Definitive Certificates as Certificateholders hereunder.

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

         (b) It is understood and agreed that the obligation under this
Agreement of the Mortgage Loan Seller or the Master Servicer to repurchase or
substitute any Mortgage Loan as to which any breach of representation or
warranty or other obligation contained in Section 2.01, 2.02, 2.03, 2.04 or 3.12
of this Agreement or in Section 2 of the Mortgage Loan Purchase Agreement has
occurred and is continuing shall constitute the sole and exclusive remedy
respecting such breach available to the Seller, the Certificateholders or the
Trustee on their behalf so long as the Mortgage Loan Seller repurchases or
substitutes any such Mortgage Loan. Neither the Certificateholders nor the
Trustee on their behalf shall be entitled to any consequential damages.

         (c) Without limiting the effect of Section 7.01(b), the Master Servicer
shall defend and indemnify the Trust Fund, the Trustee, the Seller, the
Certificate Registrar, the Mortgage Loan Seller and the Certificateholders
against any and all costs, expenses, losses, damages, claims or liabilities,
including reasonable fees and expenses of counsel and expenses of litigation,
arising from third party claims or actions (including penalties or fees imposed
by any governmental or regulatory body or agency) in respect of any breach of
the Master Servicer's covenants, representations or warranties set forth herein
or in respect of any action taken or omitted by the Master Servicer with respect
to any Mortgage Loan constituting a failure by the Master Servicer to perform
its obligations under this Agreement. This indemnity shall survive any Event of
Default (but a Master Servicer's obligations under this Section 7.01 shall not
relate to any actions of any predecessor or subsequent Master Servicer after an
Event of Default) and any payment of the amount owing under, or any repurchase
by the Master Servicer of, any such Mortgage Loan.

Seller shall defend and indemnify the Trust Fund, the Trustee, the Seller, the
Certificate Registrar, the Master Servicer and the Certificateholders against
any and all costs, expenses, losses, damages, claims or liabilities, including

Mortgage Loan Seller's covenants, representations or warranties set forth herein
or in respect of any action taken or omitted by the Mortgage Loan Seller with
respect to any Mortgage Loan constituting a failure by the Mortgage Loan Seller
to perform its obligations under this Agreement. This indemnity shall survive
any payment of the amount owing under, or any repurchase by the Mortgage Loan
Seller of, any such Mortgage Loan.

         (e) Any amounts received by the Trustee from the Mortgage Loan Seller
or Master Servicer on behalf of the Trust Fund pursuant to this Article VII
shall be deposited in the Certificate Account and shall be distributed as part
of the Total Distribution Amount. If either the Mortgage Loan Seller or the
Master Servicer has made any indemnity payments to the Trustee pursuant to this
Article VII and the Trustee thereafter collects any of such amounts from others,
the Trustee will repay such amounts collected to the Mortgage Loan Seller or
Master Servicer, as applicable, together with any interest collected thereon.

         SECTION 7.02      MERGER OR CONSOLIDATION OF THE SELLER, THE MORTGAGE
                           LOAN SELLER OR THE MASTER SERVICER.
                           ---------------------------------------------------

         (a) Subject to Section 7.02(b), the Seller, the Mortgage Loan Seller
and the Master Servicer will each do or cause to be done all things necessary to
preserve and keep in full force and effect its existence, rights and franchises
(charter and statutory) 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.

         (b) Any of the Mortgage Loan Seller, the Master Servicer or the Seller
may merge or consolidate with any Person, and any Person into which the Mortgage
Loan Seller, the Master Servicer or the Seller may be merged or consolidated, or
any Person resulting from any merger or consolidation to which the Mortgage Loan
Seller or the Master Servicer shall be a party, or any Person succeeding to the
business of the Mortgage Loan Seller, Master Servicer or the Seller, shall be
the successor of the Mortgage Loan Seller, 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, however, 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.

         (c) Notwithstanding anything else in this Section 7.02 or in Section
7.04 hereof to the contrary, the Master Servicer may assign its rights and
delegate its duties and obligations under this Agreement (except for the
obligation of the Master Servicer or Mortgage Loan Seller to effectuate
repurchases or substitutions of Mortgage Loans hereunder, including pursuant to
Section 2.01, 2.02 or 2.04 hereof, which shall remain with Washington Mutual
hereunder); provided, however, that the Master Servicer gives the Seller and the
Trustee notice of such assignment; and provided further, that such purchaser or
transferee accepting such assignment and delegation shall be an institution that
is a Fannie Mae and Freddie Mac approved seller/servicer in good standing, which
has a net worth of at least $15,000,000, and which is willing to service the
Mortgage Loans and executes and delivers to the Seller and the Trustee an
agreement accepting such delegation and assignment, which contains an assumption
by such Person of the rights, powers, duties, responsibilities, obligations and
liabilities of the Master Servicer, with like effect as if originally named as a
party to this Agreement. In the case of any such assignment and delegation, the
Master Servicer shall be released from its obligations under this Agreement
(except as provided above), except that the Master Servicer shall remain liable
for all liabilities and obligations incurred by it as Master Servicer hereunder
prior to the satisfaction of the conditions to such assignment and delegation
set forth in the preceding sentence.

         Neither the Seller nor the Master Servicer nor any of the directors,
officers, employees or agents of the Seller or the Master Servicer shall be
under any liability to 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 Seller or the Master Servicer against any breach of
representations or warranties made by it herein or protect the Seller or the
Master Servicer or any such person from any liability which would otherwise be
imposed by reasons of willful misfeasance, bad faith or negligence in the
performance of duties or by reason of reckless disregard of obligations and
duties hereunder. The Seller, the Master Servicer and any director, officer,
employee or agent of the Seller 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 Master Servicer
and any director, officer, employee or agent of the Seller 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 legal action relating
to this Agreement or the Certificates, other than any loss, liability or expense
incurred by reason of willful misfeasance, bad faith or negligence in the
performance of duties hereunder or by reason of reckless disregard of
obligations and duties hereunder. Neither the Seller nor the Master Servicer
shall be under any obligation to appear in, prosecute or defend any legal action
that is not incidental to their respective duties hereunder and which in its
opinion may involve it in any expense or liability; provided, however, that
either the Seller 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.

         SECTION 7.04      MASTER SERVICER NOT TO RESIGN.
                           -----------------------------

         The Master Servicer shall not resign from the obligations and duties
imposed upon it hereunder except upon determination that such obligations and
duties hereunder are no longer permissible under applicable law or except in
connection with a permitted assignment pursuant to Section 7.02. Any such
determination that the Master Servicer's obligations are no longer permissible
shall be evidenced by an Opinion of Counsel to such effect delivered to the
Trustee. The Master Servicer shall give notice of any proposed resignation to
the Trustee, the Certificateholders and the Rating Agencies. No such resignation
by the Master Servicer shall become effective until the Trustee or a successor
master servicer shall have assumed the Master Servicer's responsibilities and
obligations in accordance with Section 8.02 hereof or shall affect any
obligation of the Mortgage Loan Seller hereunder.

         SECTION 7.05      ERRORS AND OMISSIONS INSURANCE; FIDELITY BONDS.
                           ----------------------------------------------

under this Agreement, obtain and maintain in force (a) a policy or policies of
insurance covering errors and omissions in the performance of its obligations as

employees and agents. Each such policy or policies and bond shall, together,
comply

                                       78

<PAGE>

with the requirements from time to time of Fannie Mae or Freddie Mac for persons
performing servicing for mortgage loans purchased by Fannie Mae or Freddie Mac.
In the event that any such policy or bond ceases to be in effect, the Master
Servicer shall obtain a comparable replacement policy or bond from an insurer or
issuer, meeting the requirements set forth above as of the date of such

                                     DEFAULT

         SECTION 8.01      EVENTS OF DEFAULT.
                           -----------------

         (a) "Event of Default," wherever used herein, means any one of the
following events (whatever 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):

                  (i) any failure by the Master Servicer to remit to the Trustee
         any payment other than a Monthly Advance required to be made by the
         Master Servicer under the terms of this Agreement, which failure shall
         continue unremedied for a period of three Business Days after the date
         upon which written notice of such failure shall have been given to the
         Master Servicer by the Trustee or the Seller or to the Master Servicer
         and the Trustee by the Holders of Certificates having not less than 25%
         of the Voting Interests evidenced by the Certificates; or

                  (ii) any failure by the Master Servicer to observe or perform
         in any material respect any other of the covenants or agreements on the
         part of the Master Servicer contained in this Agreement (except as set
         forth in (iii) below) which failure (A) materially affects the rights
         of the Certificateholders and (B) shall continue unremedied for a
         period of 60 days after the date on which written notice of such
         failure shall have been given to the Master Servicer by the Trustee or
         the Seller, or to the Master Servicer and the Trustee by the Holders of
         Certificates evidencing not less than 25% of the Voting Interests
         evidenced by the Certificates; or

                  (iii) if a representation or warranty set forth in Section
         2.03 hereof shall prove to be materially incorrect as of the time made
         in any respect that materially and adversely affects interests of the
         Certificateholders, and the circumstances or condition in respect of
         which such representation or warranty was incorrect shall not have been
         eliminated or cured, or any affected Mortgage Loan shall not have been
         substituted for or repurchased, within 60 days (or, if such breach is
         not capable of being cured within 60 days and is not subject to the
         remedies set forth in Section 2.04 and provided that the Master
         Servicer believes in good faith that such breach can be cured and is
         diligently pursuing the cure thereof, within 120 days) after the date
         on which written notice thereof shall have been given to the Master
         Servicer and Mortgage Loan Seller by the Trustee for the benefit of the
         Certificateholders or by the Seller; or

                  (iv) a decree or order of a court or agency or supervisory
         authority having jurisdiction in the premises for the appointment of a
         conservator or receiver or liquidator in any insolvency, readjustment
         of debt, marshalling of assets and liabilities or similar proceedings,
         or for the winding-up or liquidation of its affairs, shall have been
         entered

<PAGE>

         against the Master Servicer and such decree or order shall have
         remained in force undischarged or unstayed for a period of 60 days; or

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

                  (vi) 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 commence a voluntary case under, any applicable
         insolvency or reorganization statute, make an assignment for the
         benefit of its creditors, or voluntarily suspend payment of its
         obligations; or

                  (vii) either Rating Agency shall lower or withdraw the
         outstanding rating of the Certificates because the existing or
         prospective financial condition or mortgage loan servicing capability
         of the Master Servicer is insufficient to maintain such outstanding
         rating; or

                  (viii) any failure of the Master Servicer to make any Monthly
         Advance in the manner and at the time required to be made from its own
         funds pursuant to this Agreement and after receipt of notice from the
         Trustee pursuant to Section 5.04, which failure continues unremedied
         after the close of business on the Business Day immediately following
         the Distribution Date.

         (b) If an Event of Default due to the actions or inaction of the Master
Servicer described in clauses (i) through (vii) of Section 8.01(a) shall occur,
then, and in each and every such case, so long as such Event of Default shall
not have been remedied, the Trustee shall, if so directed by the Holders of
Certificates evidencing not less than 25% of the Voting Interests evidenced by
the Certificates, by notice in writing to the Master Servicer (with a copy to
the Rating Agencies), terminate all of the rights and obligations of the Master
Servicer under this Agreement (other than rights to reimbursement for Monthly
Advances or other advances previously made, as provided in Section 3.09 or
4.01).

         (c) If an Event of Default described in clause (viii) shall occur, the
Trustee shall, prior to the next Distribution Date, terminate the rights and
obligations of the Master Servicer hereunder (other than rights to reimbursement
for Monthly Advances or other advances previously made, as provided in Section
3.09 or 4.01) and succeed to the rights and obligations of the Master Servicer
hereunder pursuant to Section 8.02, including the obligation to make Monthly
Advances on such Distribution Date pursuant to the terms hereof.

         SECTION 8.02      TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR.
                           ----------------------------------------

         (a) On and after the time the Master Servicer receives a notice of
termination pursuant to Section 8.01 hereof or resigns pursuant to Section 7.04
hereof, subject to the provisions of Section 3.06 hereof, the Trustee shall be
the successor in all respects to the Master Servicer in its capacity as master
servicer under this Agreement and with respect to the transactions set forth or
provided

                                       81

<PAGE>

for herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Master Servicer by the terms and
provisions hereof, provided that neither the Trustee nor any other successor to
the Master Servicer pursuant to this Section 8.02 shall be deemed to have made
any representation or warranty made by the Master Servicer, shall be obligated
to effect any repurchase or substitute of any Mortgage Loan, or shall have any
responsibility for an act or omission of any predecessor Master Servicer. As
compensation therefor, the Trustee shall be entitled to all funds relating to
the Mortgage Loans that the Master Servicer would have been entitled to charge
to the related Custodial Account if the Master Servicer had continued to act
hereunder (except that the terminated Master Servicer shall retain the right to
be reimbursed for advances (including, without limitation, Monthly Advances)
theretofore made by the Master Servicer with respect to which it would be
entitled to be reimbursed if it had not been so terminated as Master Servicer).

         Notwithstanding the foregoing, if the Trustee has become the successor
to the Master Servicer in accordance with this Section 8.02, the Trustee may, if
it shall be unwilling to so act, or shall, if it is unable to so act, appoint,
or petition a court of competent jurisdiction to appoint, any established
mortgage loan servicing institution, the appointment of which does not adversely
affect the then current rating of the Certificates, 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. Pending
appointment of a successor to the Master Servicer hereunder, the Trustee, unless
the Trustee is prohibited by law from so acting, shall act in such capacity as
provided herein. 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. The Trustee and such successor shall take such
action, consistent with this Agreement, as shall be necessary to effectuate any
such succession.

         (b) The Master Servicer that has been terminated shall, at the request
of the Trustee but at the expense of such Master Servicer, deliver to the
assuming party all documents and records relating to each Sub-Servicing
Agreement and the related Mortgage Loans and an accounting of amounts collected
and held by it and otherwise use its best efforts to effect the orderly and
efficient transfer of each Sub-Servicing Agreement to the assuming party.

         (c) The Master Servicer shall cooperate with the Trustee and any
successor Master Servicer in effecting the termination of the Master Servicer's
responsibilities and rights hereunder, including without limitation, the
transfer to such successor for administration by it of all cash amounts which
shall at the time be credited by the Master Servicer to the Custodial Account or
thereafter received with respect to the Mortgage Loans and the Master Servicer
Mortgage Files.

         (d) Neither the Trustee nor any other successor master servicer shall
be deemed to be in default hereunder by reason of any failure to make, or any
delay in making, any distribution hereunder or any portion thereof caused by (a)
the failure of the Master Servicer to (i) deliver, or any delay in delivering,
cash, documents or records to it, (ii) cooperate as required by this Agreement,
or (iii) deliver the Master Servicer Mortgage Files to the Trustee as required
by this Agreement, or (b) restrictions imposed by any regulatory authority
having jurisdiction over the Master Servicer.

                                       82

<PAGE>

         (e) Any successor to the Master Servicer as master servicer shall
during the term of its service as master servicer maintain in force the policy
or policies that the Master Servicer is required to maintain pursuant to Section
7.05 hereof. No termination of the Master Servicer shall have any affect on the
obligations of the Mortgage Loan Seller hereunder.

         SECTION 8.03      NOTIFICATION TO CERTIFICATEHOLDERS.
                           ----------------------------------

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

         (b) Within 2 Business Days after its notice of the occurrence of any
Event of Default, the Trustee shall transmit by mail to all Certificateholders
and the Rating Agencies notice of each such Event of Default hereunder known to
the Trustee, unless such Event of Default shall have been cured or waived.

         SECTION 8.04      WAIVER OF EVENTS OF DEFAULT.
                           ---------------------------

         The Holders representing at least 66-2/3% of the Voting Interests of
Certificates affected by a default or Event of Default hereunder may waive any
default or Event of Default, provided, however, that (a) a default or Event of
Default under clause (i) or (viii) of Section 8.01(a) may be waived only by
Holders of Certificates of 100% of the Class affected by such default or Event
of Default and (b) no waiver pursuant to this Section 8.04 shall affect the
Holders of Certificates in the manner set forth in Section 11.01(b)(i), (ii) or
(iii). Upon any such waiver of a default or Event of Default by the Holders
representing the requisite percentage of Voting Interests 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.

                             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 that may have occurred,
undertakes with respect to the Trust Fund to perform such duties and only such
duties as are specifically set forth in this Agreement. In case an Event of
Default has occurred and remains uncured and not 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 person would
exercise or use under the circumstances in the conduct of such person's own
affairs. Any permissive right of the Trustee set forth in this Agreement shall
not be construed as a duty.

         (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee that are specifically required to be furnished pursuant to any
provision of this Agreement shall examine them to determine whether they conform
to the requirements of this Agreement. The Trustee shall have no duty to
recompute, recalculate or verify the accuracy of any resolution, certificate,
statement, opinion, report, document, order or other instrument so furnished to
the Trustee.

         (c) 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 misconduct, its negligent failure to perform its obligations
in compliance with this Agreement, or any liability which would be imposed by
reason of its willful misfeasance or bad faith; 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 that 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 personally 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 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 which it reasonably believed in good
         faith to be genuine and to have been duly executed by the proper
         authorities respecting any matters arising hereunder;

                  (ii) the Trustee shall not be personally liable for an error
         of judgment made in good faith by a Responsible Officer or Responsible
         Officers of the Trustee, unless the Trustee was negligent or acted in
         bad faith or with willful misfeasance;

                  (iii) the Trustee shall not be personally liable with respect
         to any action taken, suffered or omitted to be taken by it in good
         faith in accordance with the direction of Holders of Certificates
         evidencing not less than 25% of the Voting Interests allocated to each
         Class

                                       84

<PAGE>

         of Certificates 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;
         and

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

         (d) Except with respect to an Event of Default described in clause (i)
of Section 8.01(a), the Trustee shall not be deemed to have knowledge of any
Event of Default or event which, with notice or lapse of time, or both, would
become an Event of Default, unless a Responsible Officer of the Trustee shall
have received written notice thereof from the Master Servicer, the Seller or a
Certificateholder, or a Responsible Officer of the Trustee has actual notice
thereof, and in the absence of such notice no provision hereof requiring the
taking of any action or the assumption of any duties or responsibility by the
Trustee following the occurrence of any Event of Default or event which, with
notice or lapse of time or both, would become an Event of Default, shall be
effective as to the Trustee.

         (e) The Trustee shall have no duty hereunder with respect to any
complaint, claim, demand, notice or other document it may receive or which may
be alleged to have been delivered to or served upon it by the parties as a
consequence of the assignment of any Mortgage Loan hereunder; provided, however,
that the Trustee shall use its best efforts to remit to the Master Servicer,
upon receipt, any such complaint, claim, demand, notice or other document (i)
which is delivered to the Corporate Trust Office of the Trustee, (ii) of which a
Responsible Officer has actual knowledge, and (iii) which contains information
sufficient to permit the Trustee to make a determination that the real property
to which such document relates is a Mortgaged Property.

         SECTION 9.02      CERTAIN MATTERS AFFECTING THE TRUSTEE.
                           -------------------------------------

         (a) Except as otherwise provided in Section 9.01:

                  (i) the Trustee may request and rely upon and shall be
         protected in acting or refraining from acting upon any resolution,
         Officers' Certificate, certificate of Servicing Officers, 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 or 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 with such Opinion of Counsel;

                  (iii) the Trustee shall be under no obligation to exercise any
         of the trusts or powers vested in it by 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

                                       85

<PAGE>

         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 (which has not been cured or waived), 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 or use under the circumstances in the conduct of such person's
         own affairs;

                  (iv) the Trustee shall not be personally 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;

                  (v) prior to the occurrence of an Event of Default hereunder
         and after the curing or waiving of all Events of Default that 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 so to do
         by Holders of Certificates evidencing not less than 25% of the Voting
         Interests allocated to each Class of Certificates; 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, not
         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 investigation shall be
         paid by the Master Servicer in the event that such investigation
         relates to an Event of Default by the Master Servicer, if an Event of
         Default by the Master Servicer shall have occurred and is continuing,
         and otherwise by the Certificateholders requesting the investigation;

                  (vi) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or by or
         through affiliates, agents or attorneys;

                  (vii) the Trustee shall not be required to expend its own
         funds or otherwise incur any financial liability in the performance of
         any of its duties hereunder if it shall have reasonable grounds for
         believing that repayment of such funds or adequate indemnity against
         such liability is not assured to it; and

                  (viii) the Trustee shall not be liable for any loss on any
         investment of funds pursuant to this Agreement.

         (b) All rights of action under this Agreement or under any of the
Certificates, enforceable by the Trustee, may be enforced by it without the
possession of any of the Certificates, or the production thereof at the trial or
other proceeding relating thereto, and any such suit, action or proceeding
instituted by the Trustee shall be brought in its name for the benefit of all
the Holders of such Certificates, subject to the provisions of this Agreement.

responsibility for their correctness. The Trustee makes no representations as to

by reason of willful misfeasance, bad faith or negligence in the performance of
any of the Trustee's duties hereunder or by reason of reckless disregard of the
Trustee's obligations and duties hereunder and (ii) resulting from the exercise
of any power of attorney granted by the Trustee to the Master Servicer in

                           ------------------------------------

         The Trustee hereunder shall at all times be a corporation or

         SECTION 9.07      RESIGNATION AND REMOVAL OF TRUSTEE.
                           ----------------------------------

         (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by (i) giving written notice of resignation to the Seller,
the Mortgage Loan Seller and the Master Servicer and by mailing notice of
resignation by first class mail, postage prepaid, to the Certificateholders at
their addresses appearing on the Certificate Register, and to the Rating
Agencies, not less than 60 days before the date specified in such notice when,
subject to Section 9.08, such resignation is to take effect, and (ii) acceptance
by a successor trustee in accordance with Section 9.08 meeting the
qualifications set forth in Section 9.06. 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.

         (b) If at any time (i) the Trustee shall cease to be eligible in
accordance with the provisions of Section 9.06 hereof and shall fail to resign
after written request thereto by the Master Servicer, (ii) 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, (iii) a
tax is imposed or threatened with respect to the Trust Fund by any state in
which the Trustee or the Trust Fund held by the Trustee is located, (iv) the
continued use of the Trustee would result in a downgrading of the rating by the
Rating Agencies of any Class of Certificates with a rating or (v) the Trustee
breaches any of its obligations or representations hereunder, then the Seller,
with the consent of the Master Servicer, may remove the Trustee and, with the
consent of the Master Servicer, appoint a successor trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
Trustee and one copy to the successor trustee. The Trustee may also be removed
at any time by the Holders of Certificates evidencing not less than 50% of the
Voting Interests evidenced by the Certificates. Notice of any removal of the
Trustee and acceptance of appointment by the successor trustee shall be given to
the Rating Agencies by the Master Servicer.

         (c) Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 9.07 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 9.08 hereof.

         SECTION 9.08      SUCCESSOR TRUSTEE.
                           -----------------

         (a) If the Trustee resigns pursuant to Section 9.07, the Seller, with
the consent of the Master Servicer, shall appoint a successor trustee that
satisfies the requirements of Section 9.06. Any successor trustee appointed as
provided in Section 9.07 hereof shall execute, acknowledge and deliver to the
Seller and 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 Seller and the
predecessor trustee shall execute and deliver such instruments and do such other
things as may reasonably be required

                                       88

<PAGE>

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 9.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 9.06 hereof and shall not adversely
affect the then current rating of the Certificates.

         (c) Upon acceptance of appointment by a successor trustee as provided
in this Section 9.08, 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
Seller.

         SECTION 9.09      MERGER OR CONSOLIDATION OF TRUSTEE.
                           ----------------------------------

         Any Person into which the Trustee may be merged or converted or with
which it may be consolidated or any Person resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any Person succeeding
to the business of the Trustee, shall be the successor of the Trustee hereunder,
provided that such Person shall be eligible under the provisions of Section 9.06
hereof without the execution or filing of any paper or further act on the part
of any of the parties hereto, anything herein to the contrary notwithstanding.

         SECTION 9.10      APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
                           ---------------------------------------------

         (a) Notwithstanding any other provisions of this Agreement, 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 any Mortgage Note 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 and
for the benefit of the applicable Certificateholders, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
9.10, 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 fifteen days after the receipt
by it of a request to do so, or in the case an Event of Default shall have
occurred and be continuing, the Trustee alone shall have the power to make such
appointment. No co-trustee or separate trustee hereunder shall be required to
meet the terms of eligibility as a successor trustee under Section 9.06 and no
notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 9.08.

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

                  (i) all rights, powers, duties and obligations conferred or
         imposed upon the Trustee, except for any obligation of the Trustee
         under this Agreement to advance funds on behalf of the Master Servicer,
         shall be conferred or imposed upon and exercised or

                                       89

<PAGE>

         performed by the Trustee and such separate trustee or co-trustee
         jointly (it being understood that such separate trustee or co-trustee
         is not authorized to act separately without the Trustee joining in such
         act), except to the extent that under any law of any jurisdiction in
         which any particular act or acts are to be performed by the Trustee
         (whether as Trustee hereunder or as successor to the Master Servicer),
         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
         singly by such separate trustee or co-trustee, but solely at the
         direction of the Trustee;

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

                  (iii) the Master Servicer and the Trustee acting jointly may
         at any time accept the resignation of or remove any separate trustee or
         co-trustee.

         (c) Any notice, request or other writing given to the 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 and a copy thereof given to the
Master Servicer and the Seller.

         (d) 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.

         (e) The Trustee agrees to instruct the co-trustees, if any, to the
extent necessary to fulfill the Trustee's obligations hereunder.

         (f) The Master Servicer shall pay what it determines in its sole
discretion to be the reasonable compensation of any co-trustee required to be
appointed hereunder, provided that any such expenditure shall be a reimbursable
expense of the Master Servicer from funds on deposit in the Custodial Account
pursuant to Section 3.09(a)(vii).

demands is the Corporate Trust Office.

         SECTION 9.12      TAX RETURNS, 1934 ACT REPORTING, OTHER DATA.
                           -------------------------------------------

         (a) The Trustee shall prepare or cause to be prepared on behalf of the
Trust Fund, based upon the information furnished by the Master Servicer or
calculated by the Trustee in accordance with this Agreement pursuant to
instructions given by the Seller, and shall file federal tax returns and
appropriate state income tax returns and such other returns as may be required
by applicable law relating to the Trust Fund and shall forward copies to the
Seller of all such returns and Form 1099 information and such other information
within the control of the Trustee as the Seller may reasonably request in
writing, and shall forward to each Certificateholder such forms and furnish such
information within the control of the Trustee as are required by the Code and
the REMIC Provisions to be furnished to them, and will prepare and disseminate
to Certificateholders Form 1099s (or otherwise furnish information within the
control of the Trustee) to the extent required by applicable law.

         (b) The Trustee shall prepare and file with the Internal Revenue
Service ("IRS"), on behalf of the Trust Fund, an application on IRS Form SS-4.

         (c) Within 15 days after each Distribution Date, the Trustee shall, in
accordance with industry standards, file with the Securities and Exchange
Commission via the Electronic Data Gathering and Retrieval System ("EDGAR"), a
Form 8-K with a copy of the statement to the Certificateholders for such
Distribution Date as an exhibit thereto. The Trustee shall, in accordance with
industry standards and only when instructed by the Seller, file a Form 15
Suspension Notice with respect to the Trust Fund, if applicable. Prior to March
31 of each calendar year commencing March 31, 2001, 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 Securities and Exchange Commission. The Trustee
shall have no responsibility to file any items other than those specified in
this Section 9.12(c); 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 9.12(c) shall not be reimbursable from the Trust
Fund.

         SECTION 10.01     TERMINATION UPON LIQUIDATION OR REPURCHASE OF ALL
                           MORTGAGE LOANS.
                           -------------------------------------------------

         (a) The obligations and responsibilities of the Master Servicer, the
Mortgage Loan Seller, the Seller and the Trustee created hereby with respect to
the Trust Fund created hereby shall terminate upon the earlier of:

                  (i) the repurchase by the Master Servicer at its election, of
         all Mortgage Loans and all property acquired in respect of any Mortgage
         Loan remaining in the Trust Fund, which repurchase right the Master
         Servicer may exercise at its sole and exclusive election as of any
         Distribution Date (such applicable Distribution Date being herein
         referred to as the "Optional Termination Date") following the
         Distribution Date on which the aggregate Scheduled Principal Balance of
         the Mortgage Loans at the time of the repurchase is less than or equal
         to 10% of the aggregate Scheduled Principal Balance of the Mortgage
         Loans as of the Cut-off Date; and

                  (ii) the later of (A) twelve months after the maturity of the
         last Mortgage Loan remaining in the Trust Fund, (B) the liquidation (or
         any advance with respect thereto) of the last Mortgage Loan remaining
         in the Trust Fund and the disposition of all REO Property and (C) the
         distribution to Certificateholders of all amounts required to be
         distributed to them pursuant to this Agreement.

In no event shall the trust created hereby continue beyond the expiration of 21
years from the death of the last survivor of the descendants of Mr. Joseph P.
Kennedy, former Ambassador of the United States to Great Britain, living on the
date of execution of this Agreement. Any termination of the Trust Fund pursuant
to clause (i) above shall be carried out in such a manner so that the
termination of the REMIC included therein shall qualify as a "qualified
liquidation" under the REMIC Provisions.

         (b) The Mortgage Loan Repurchase Price for any such Optional
Termination of the Trust Fund shall be equal to the Aggregate Loan Balance of
the Mortgage Loans as of the date of repurchase, together with accrued and
unpaid interest thereon from the date to which such interest was paid or
advanced at the sum of the applicable Net Mortgage Rate with respect to each
Mortgage Loan through the last day of the month of such repurchase, plus any
sums on account of such Mortgage Loan that have been advanced by the Master
Servicer and are reimbursable to the Master Servicer hereunder (including the
Scheduled Principal Balance of each Mortgage Loan that was secured by any REO
Property); provided, however, that if the Master Servicer shall so choose, the
Master Servicer may remit the Mortgage Loan Repurchase Price net of advances
that would otherwise be reimbursable to the Master Servicer and the Master
Servicer will have no further entitlement to reimbursement for such advances.
The Trustee shall give notice to the Rating

pursuant to this Section 10.01 and of the Optional Termination Date.

         SECTION 10.02     PROCEDURE UPON OPTIONAL OR OTHER FINAL TERMINATION.
                           --------------------------------------------------

         (a) In case of any Optional Termination pursuant to Section 10.01, the
Master Servicer shall, at least twenty days prior to the date notice is to be
mailed to the affected Certificateholders pursuant to Section 10.02(c), notify
the Trustee of such Optional Termination Date and of the Mortgage Loan
Repurchase Price.

         (b) Any repurchase of the Mortgage Loans by the Master Servicer shall
be made on an Optional Termination Date by deposit of the Mortgage Loan
Repurchase Price into the Certificate Account before the Distribution Date on
which such repurchase is effected. Upon receipt by the Trustee of an Officers'
Certificate of the Master Servicer certifying as to the deposit of such
repurchase price into the Certificate Account, the Master Servicer shall prepare
and the Trustee and each co-trustee and separate trustee, if any, then acting as
such under this Agreement, shall, upon request and at the expense of the Master
Servicer execute and deliver all such instruments of transfer or assignment, in
each case without recourse, as shall be necessary, to vest title in the Master
Servicer in the Mortgage Loans so repurchased and shall transfer or deliver to
the Master Servicer the repurchased Mortgage Loans. Any distributions on the
Mortgage Loans received by the Trustee subsequent to (or with respect to any
period subsequent to) the Optional Termination Date shall be promptly remitted
by it to the Master Servicer.

         (c) Notice of the Distribution Date on which the Master Servicer
anticipates that the final distribution shall be made (whether upon Optional
Termination or otherwise), shall be given promptly by the Master Servicer to the
Trustee and by the Trustee by first class mail to Holders of the affected
Certificates. Such notice shall be mailed no earlier than the 15th day and not
later than the 10th day preceding the Optional Termination Date or date of final
distribution, as the case may be. Such notice shall specify (i) the Distribution
Date upon which final distribution on the affected Certificates will be made
upon presentation and surrender of such Certificates at the office or agency
therein designated, (ii) the amount of such final distribution and (iii) that
the Record Date otherwise applicable to such Distribution Date is not
applicable, such distribution being made only upon presentation and surrender of
such Certificates at the office or agency maintained for such purposes (the
address of which shall be set forth in such notice).

         (d) In the event that any Certificateholders shall not surrender
Certificates for cancellation within six months after the date specified in the
above mentioned written notice, the Trustee shall give a second written notice
to the remaining such Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice all the Certificates shall not have been
surrendered for cancellation, the Trustee may take appropriate steps, or may
appoint an 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
the Trust Fund. If, after such actions have been taken, such Certificates have
not been surrendered for cancellation, the Trustee shall pay over all such
remaining funds to the Seller.

                           -----------------------------------

         (a) In the event the Master Servicer exercises its purchase option
pursuant to Section 10.01, the Trust Fund shall be terminated in accordance with
the following additional requirements, unless the Trustee has received an
Opinion of Counsel to the effect that the failure of the Trust Fund to comply
with the requirements of this Section will not (i) result in the imposition of
taxes on a "prohibited transaction" of the Trust Fund, as described in Section
860F of the Code, or (ii) cause the Trust Fund to fail to qualify as a REMIC at
any time that any Certificates are outstanding:

                  (i) within 90 days prior to the final Distribution Date set
         forth in the notice given by the Master Servicer under Section 10.02,
         the Trustee shall adopt a plan of complete liquidation of the Trust
         Fund and specify the first day of the applicable 90-day liquidation
         period in a statement attached to the Trust Fund's final tax return
         pursuant to Treasury Regulations Section 1.860F-1, and satisfy (or
         cause to be satisfied) all of the requirements of a qualified
         liquidation under the REMIC Provisions; and

                  (ii) at or after the time of adoption of any such plan of
         complete liquidation for the Trust Fund at or prior to the Final
         Distribution Date, the Trustee shall sell all of the assets (if any) of
         the Trust Fund to the Master Servicer for cash; provided, however, that
         in the event that a calendar quarter ends after the time of adoption of
         such a plan of complete liquidation but prior to the final Distribution
         Date, the Trustee shall not sell any of the assets of the Trust Fund
         prior to the close of that calendar quarter.

         (b) By its acceptance of a Class R Certificate, the Holders thereof
hereby agree to adopt such a plan of complete liquidation and to take such other
action in connection therewith as may be reasonably required to liquidate and
otherwise terminate the Trust Fund.

         received an Opinion of Counsel to the effect that (A) such action is
         necessary or desirable to maintain such qualification or to avoid or

         SECTION 11.04     INTENTION OF PARTIES.
                           --------------------

         (a) It is the express intent of the Seller, the Mortgage Loan Seller,
the Master Servicer and the Trustee that the conveyance by the Mortgage Loan
Seller to the Seller pursuant to the Mortgage Loan Purchase Agreement and the
conveyance by the Seller to the Trustee and by the Mortgage Loan Seller to the
Trustee as provided for in Section 2.01 of each of the Mortgage Loan Seller's
and Seller's right, title and interest in and to the Mortgage Loans be, and be
construed as, an absolute sale and assignment by the Mortgage Loan Seller to the
Seller and by the Seller to the Trustee of the Mortgage Loans for the benefit of
the Certificateholders. Further, it is not intended that either conveyance be
deemed to be a pledge of the Mortgage Loans by the Mortgage Loan Seller to the
Seller or by the Seller to the Trustee to secure a debt or other obligation.
However, in the event that the Mortgage Loans are held to be property of the
Mortgage Loan Seller or the Seller, or if for any reason the Mortgage Loan
Purchase Agreement or this Agreement is held or deemed to create a security
interest in the Mortgage Loans, then it is intended that (i) 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; (ii) the conveyances provided for in Section
2.01 shall be deemed to be a grant by the Mortgage Loan Seller and the Seller to
the Trustee on behalf of the Certificateholders, to secure payment in full of
the Secured Obligations (as defined below), of a security interest in all of the
Mortgage Loan Seller's and the Seller's right (including the power to convey
title thereto), title and interest, whether now owned or hereafter acquired, in
and to the Mortgage Loans, including the Mortgage Notes, the Mortgages, any
related insurance policies and all other documents in the related Trustee
Mortgage Files, and all accounts, general intangibles, chattel paper,
instruments, documents, money, deposit accounts, certificates of deposit, goods,
letters of credit, advices of credit and investment property consisting of the
Trust Fund, arising from or relating to (A) the Mortgage Loans, including with
respect to each Mortgage Loan, the Mortgage Note and related Mortgage, and all
other documents in the related Trustee Mortgage Files, and including any
Replacement Mortgage Loans; (B) pool insurance policies, hazard insurance
policies and any bankruptcy bond relating to the foregoing, if applicable; (C)
the Certificate Account; (D) the Custodial Account; (E) all amounts payable on
or after the Cut-off Date to the holders of the Mortgage Loans in accordance
with the terms thereof; (F) all income, payments, proceeds and products 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, whether in the form of
cash, instruments, securities or other property; and (G) all cash and non-cash
proceeds of any of the foregoing; (iii) the possession or control by the Trustee
or any other agent of the Trustee of Mortgage Notes or such other items of
property as constitute instruments, money, documents, advices of credit, letters
of credit, goods, certificated securities or chattel paper shall be deemed to be
possession or control by the secured party, or possession or control by a
purchaser, for purposes of perfecting the

                                       98

<PAGE>

security interest pursuant to the Uniform Commercial Code (including, without
limitation, Sections 9-305 or 9-115 thereof); and (iv) 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, securities intermediaries,
bailees or agents of, or persons holding for, the Trustee, as applicable, for
the purpose of perfecting such security interest under applicable law. "Secured
Obligations" means (i) the rights of each Certificateholder to be paid any
amount owed to it under this Agreement, (ii) all other obligations of the
Mortgage Loan Seller and the Seller under this Agreement and the Mortgage Loan
Purchase Agreement and (iii) the right of the Certificateholders to the Mortgage
Loans.

         (b) The Mortgage Loan Seller and the Seller, and, at the Seller's
direction, the Master Servicer and the Trustee, shall, to the extent consistent
with this Agreement, take such reasonable actions as may be necessary to ensure
that, if this Agreement were deemed to create a security interest in the
Mortgage Loans and the other Trust Fund property described above, such security
interest would be deemed to be a perfected security interest of first priority
as applicable. The Master Servicer shall file, at its expense, all filings
necessary to maintain the effectiveness of any original filings necessary under
the Uniform Commercial Code as in effect in any jurisdiction to perfect the
Trustee's security interest in or lien on the Mortgage Loans, including without
limitation (i) continuation statements, (ii) such other statements as may be
occasioned by any transfer of any interest of the Master Servicer or the Seller
in any Mortgage Loan; and filings necessary as a result in any change in the
UCC.

                           ------------------------------------------

         (a) The death or incapacity of any Certificateholder shall not operate
to terminate this Agreement or the Trust Fund, nor entitle such
Certificateholder's legal representative or heirs to claim an accounting or to
take any action or commence any proceeding in any court for a petition or
winding up of the Trust Fund, or otherwise affect the rights, obligations and

         (b) No Certificateholder shall have any right to vote (except as
provided herein) or in any manner otherwise control the operation and management

         (c) No Certificateholder shall have any right by virtue or by availing

upon the Trustee to institute such action, suit or proceeding in its own name as

         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 conventional one- to four-family adjustable interest rate
         mortgage loans 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. 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
Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial Current Principal Amount of this Certificate by the aggregate Initial
Current Principal Amount of all Class A Certificates, both as specified above)
in the beneficial ownership interest of Certificates of the same Class as this
Certificate in a trust (the "Trust Fund") generally consisting of conventional
first lien, adjustable rate mortgages loans secured by 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 Washington Mutual
Bank, FA (in such capacity, the "Mortgage Loan Seller") to SAMI. Washington
Mutual Bank, FA 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

                                       A-2

<PAGE>

pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date
specified above (the "Agreement"), between SAMI, as seller (the "Seller"), the
Master Servicer, the Mortgage Loan Seller 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, 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. 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 Percentage 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 first anniversary of the Distribution Date
immediately following 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 eight 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 Mortgage Loan Seller and the Master Servicer and
the rights of the Certificateholders under the Agreement from time to time by
the Seller, the Mortgage Loan Seller, the Master Servicer and the Trustee with
the consent of the Holders of Certificates evidencing Voting Interests
aggregating not less than 66-2/3% (or in certain cases, Holders of Certificates
of affected Classes evidencing such percentage of the Voting 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 Percentage 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 Percentage 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 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 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 scheduled principal balance of the

                                       A-4

<PAGE>

Mortgage Loans is less than the percentage of the aggregate Scheduled Principal
Balance specified in the Agreement of the 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 2000-3

         evidencing a percentage interest in the distributions allocable to the
         Class M-__ Certificates with respect to a Trust Fund consisting
         primarily of a pool of conventional one- to four-family adjustable
         interest rate mortgage loans 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. 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
Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial Current Principal Amount of this Certificate by the aggregate Initial
Current Principal Amount of all Class M-__ Certificates, both as specified
above) in the beneficial ownership interest of Certificates of the same Class as
this Certificate in a trust (the "Trust Fund") generally consisting of
conventional first lien, adjustable rate mortgages loans secured by 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 Washington
Mutual Bank, FA (in such capacity, the "Mortgage Loan Seller") to SAMI.
Washington Mutual Bank, FA 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

                                       B-2

<PAGE>

pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date
specified above (the "Agreement"), between SAMI, as seller (the "Seller"), the
Master Servicer, the Mortgage Loan Seller 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, 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. 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 Percentage 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 first anniversary of the Distribution Date
immediately following 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 eight 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.

attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Percentage Interest
will be issued to the designated transferee.

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 scheduled principal balance of the

Mortgage Loans is less than the percentage of the aggregate Scheduled Principal
Balance specified in the Agreement of the 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

                                  SERIES 2000-3

         evidencing a percentage interest in the distributions allocable to the
         Class B-__ Certificates with respect to a Trust Fund consisting
         primarily of a pool of conventional one- to four-family adjustable
         interest rate mortgage loans 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. 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
Percentage Interest evidenced by this Certificate (obtained by dividing the
Initial Current Principal Amount of this Certificate by the aggregate Initial
Current Principal Amount of all Class B-__ Certificates, both as specified
above) in the beneficial ownership interest of Certificates of the same Class as
this Certificate in a trust (the "Trust Fund") generally consisting of
conventional first lien, adjustable rate mortgages loans secured by 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 Washington
Mutual Bank, FA (in such capacity, the "Mortgage Loan Seller") to SAMI.
Washington Mutual Bank, FA 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

                                       C-3

<PAGE>

pursuant to the Pooling and Servicing Agreement dated as of the Cut-off Date
specified above (the "Agreement"), between SAMI, as seller (the "Seller"), the
Master Servicer, the Mortgage Loan Seller 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, 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. 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 Percentage 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 first anniversary of the Distribution Date
immediately following 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
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 eight 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 Mortgage Loan Seller and the Master Servicer and
the rights of the Certificateholders under the Agreement from time to time by
the Seller, the Mortgage Loan Seller, the Master Servicer and the Trustee with
the consent of the Holders of Certificates evidencing Voting Interests
aggregating not less than 66-2/3% (or in certain cases, Holders of Certificates
of affected Classes evidencing such percentage of the Voting 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 Percentage 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 Percentage 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 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 scheduled principal balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified in the
Agreement of the 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.

"Agreement"), between SAMI, as seller (the "Seller"), the Master Servicer, the
Mortgage Loan Seller and Bankers Trust Company of California, N.A., as trustee

and the amount (of interest and principal, if any) required to be distributed to

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 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 Company,
which purchaser may be the Seller, or any affiliate of the Seller, on such terms
and conditions as the Seller may choose.

                  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

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

on the part of the Seller, the Master Servicer or the Trustee, which will be

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 eight 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 Mortgage Loan Seller and the Master Servicer and
the rights of the Certificateholders under the Agreement from time to time by
the Seller, the Mortgage Loan Seller, the Master Servicer and the Trustee with
the consent of the Holders of Certificates evidencing Voting Interests
aggregating not less than 66-2/3% (or in certain cases, Holders of Certificates
of affected Classes evidencing such percentage of the Voting 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

                                       D-5

<PAGE>

thereupon one or more new Certificates in authorized denominations representing
a like aggregate Percentage 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 Percentage 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 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 scheduled principal balance of the Mortgage Loans is less than the
percentage of the aggregate Scheduled Principal Balance specified in the
Agreement of the 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.

         2. The Investor either (x) is not an employee benefit plan subject to
Section 406 or Section 407 of the Employee Retirement Income Security Act of
1974, as amended ("ERISA"), or Section 4975 of the Internal Revenue Code of

Agreement, no transfer of a Class [B-1][B-2][B-3] Certificate shall be permitted

Mortgage Investments Inc., as Seller, Bankers Trust Company of California, N.A.,
as Trustee and Washington Mutual Bank, FA, as Mortgage Loan Seller and Master
Servicer, dated as of December 1, 2000, no transfer of a Residual Certificate

<PAGE>

ERISA or a plan subject to Section 4975 of the Code and is not using the assets
of any employee benefit plan or other plan to acquire a Residual Certificate.

holding such Residual Certificate as they become due.

Person that holds a Residual Certificate in connection with the conduct of a
trade or business within the United States and has furnished the transferor and
the Trustee with an effective Internal Revenue Service Form 4224 or successor
form at the time and in the manner required by the Code. "Non-U.S. Person" means
any person other than (i) a citizen or resident of the United States; (ii) a
corporation (or entity treated as a corporation for tax purposes) created or
organized in the United States or under the laws of the United States or of any

the United States or under the laws of the United States or of any state
thereof, including, for this purpose, the District of Columbia (unless provided
otherwise by future Treasury regulations) provided that, for purposes solely of
the Class R Certificates, no partnership or other entity treated as a

United States Person unless all persons that own an interest in such partnership

States federal income tax purposes are United States Persons; (iv) an estate

affidavit of _____________________________ (the "Transferee"), and has no actual
knowledge that such affidavit is not true and has no reason to believe that the

has no reason to believe that the Transferee has the intention to impede the
assessment or collection of any federal, state or local taxes legally required
to be paid with respect to a Residual Certificate. In addition, the Transferor
has conducted a reasonable investigation at the time of the transfer and found
that the Transferee had historically paid its debts as they came due and found
no significant evidence to indicate that the Transferee will not continue to pay
its debts as they become due.

                             A DELAWARE CORPORATION

Pursuant to Section 151 and Section 103 of the General Corporation Law of the
State of Delaware, Steven Gillis and Kathleen McKereghan hereby certify that:

        (a)    They are the duly elected Chief Executive Officer and Secretary,
respectively, of Corixa Corporation, a Delaware corporation (the "Corporation").

        (b)    Pursuant to the authority conferred upon the Board of Directors
of the Corporation by the second paragraph of Article IV of the Corporation's
Fifth Amended and Restated Certificate of Incorporation (the "Certificate"), the
Board of Directors of the Corporation on December 24, 2000 adopted the following
recitals and resolutions creating a new series of preferred stock designated as
Series B Preferred Stock:

        "WHEREAS, the Certificate provides for a class of shares known as
Preferred Stock, issuable from time to time in one or more series;

        WHEREAS, the Board of Directors of the Corporation is authorized by the
Certificate to determine the powers, rights, preferences, limitations and
restrictions granted to or imposed upon any wholly unissued series of Preferred
Stock, to fix the number of shares constituting any such series, and to
determine the designation thereof, or any of them;

        WHEREAS, the Board of Directors of the Corporation desires, pursuant to
its authority as aforesaid, to determine and fix the powers, rights preferences,
limitations and restrictions relating to a series of Preferred Stock and the
number of shares constituting, and the designation of, such series;

        NOW, THEREFORE, BE IT RESOLVED, that pursuant to the authority vested in
the Board of Directors of the Corporation in accordance with the provisions of
the Certificate, a new series of Preferred Stock to be designated "Series B
Preferred Stock," is hereby created, and the Board of Directors hereby fixes and
determines the designation of, the number of shares constituting, and the
rights, preferences, privileges and restrictions relating to, such series of
Preferred Stock as follows (all terms used herein which are not otherwise
defined shall have the meanings set forth in the Certificate):

        1.     Designation. The series of Preferred Stock of the Corporation
(the "Preferred Stock") shall be designated as "Series B Preferred Stock" with a
par value of $0.001 per share.

        2.     Authorized Number. The number of shares constituting the Series B
Preferred Stock shall be Thirty Seven Thousand Five Hundred (37,500) shares. The
rights, preferences, restrictions and other matters relating to the Series B
Preferred Stock set forth below are subject to the issuance of any subsequent
series of preferred stock. The Board of Directors is also

<PAGE>   2
authorized to decrease the number of shares of any series of preferred stock
prior or subsequent to the issue of that series, but not below the number of
shares of such series then outstanding. In case the number of shares of any
series shall be so decreased, the shares constituting such decrease shall resume
the status which they had prior to the adoption of the resolution originally
fixing the number of shares of such series.

        3.     Dividend Provisions.

               (A)    Subject to the prior and superior rights of the holders of
any shares of any series of Preferred Stock which may from time to time come
into existence ranking prior and superior to the shares of Series B Preferred
Stock with respect to dividends and to the provisions of this Section 3, the
holders of the Series B Preferred Stock shall be entitled to receive, when, as,
and if declared by the Board of Directors out of funds legally available for
such purpose, dividends at the rate of $50.00 per annum per share, and no more,
which shall be cumulative, shall accrue without interest (except as otherwise
provided herein as to dividends in arrears) from the date of original issuance
of such share of Series B Preferred Stock (the "Issuance Date" with respect to
such share) and shall be payable on an annual basis in cash or in shares of
Common Stock as provided herein, on the date that is the yearly anniversary of
the Issuance Date applicable to such share of Series B Preferred Stock (each
such date being referred to herein as an "Annual Dividend Payment Date"), to
holders of Series B Preferred Stock of record as they appear on the stock books
of the Corporation on such record dates, not more than thirty (30) days
preceding the payment dates for such dividends, as shall be fixed by the Board.

               Dividends shall begin to accrue and be cumulative on outstanding
shares of Series B Preferred Stock from the Issuance Date with respect to such
shares. Dividends on the Series B Preferred Stock shall be paid in cash or
shares of Common Stock or any combination of cash and shares of Common Stock, at
the option of the Corporation as hereinafter provided. No dividends or other
distributions, other than dividends payable solely in shares of Common Stock,
shall be paid or set apart for payment on any shares of Common Stock, and no
purchase, redemption, or other acquisition shall be made by the Corporation of
any shares of Common Stock (other than pursuant to any stock repurchase rights
in existence prior to the date of issuance of the Series B Preferred Stock and
the repurchase of shares of Common Stock from employees, officers, directors,
consultants or other persons performing services for the Corporation or any
subsidiary pursuant to agreements under which the Corporation has the option to
repurchase such shares at cost upon the occurrence of certain events, such as
the termination of employment, or through the exercise of any right of first
refusal) unless and until all accrued and unpaid dividends (and applicable
Arrearage Interest (as defined in Section 3(C) below) on dividends in arrears)
on the Series B Preferred Stock shall have been paid or declared and set apart
for payment.

               Any references to "distribution" contained in this Section 3
shall not be deemed to include any stock dividend or distributions made in
connection with any liquidation, dissolution, or winding up of the Corporation,
whether voluntary or involuntary.

               (B)    If the Corporation elects in the exercise of its sole
discretion to issue shares of Common Stock in payment of dividends on the Series
B Preferred Stock with respect to any Annual Dividend Payment Date, the
Corporation shall (1) give notice to the holders of the

                                      -2-
<PAGE>   3
Series B Preferred Stock at least five days prior to the applicable Annual
Dividend Payment Date of the Corporation's election to exercise such right and
(2) deliver, or cause to be delivered, by the fifth trading day after such
Annual Dividend Payment Date to each holder of such shares the number of whole
shares of Common Stock arrived at by dividing (i) the applicable per share
Conversion Price of such shares of Common Stock (as determined in accordance
with Section 6(C) below) into (ii) the total amount of cash dividends such
holder would be entitled to receive if the aggregate dividends on the Series B
Preferred Stock held by such holder which are being paid in shares of Common
Stock were being paid in cash. No fractional shares of Common Stock shall be
issued in payment of dividends. In lieu thereof, the Corporation shall pay cash
in an amount equal to the product of (x) the applicable Conversion Price
multiplied by (y) the fraction of a share of Common Stock which would otherwise
be issuable by the Corporation.

               Shares of Common Stock issued in payment of dividends on Series B
Preferred Stock pursuant to this Section shall be, and for all purposes shall be
deemed to be, validly issued, fully paid and nonassessable shares of Common
Stock; the issuance and delivery thereof is hereby authorized; and the dispatch
in full thereof will be, and for all purposes shall be deemed to be, payment in
full of the cumulative dividends to which holders are entitled on the applicable
Annual Dividend Payment Date.

               (C)    In the event the Corporation fails to elect whether to pay
dividends with respect to a particular Annual Dividend Payment Date in cash, in
shares of Common Stock, or in any combination of cash and shares of Common Stock
within thirty (30) days following such Annual Dividend Payment Date and fails to
pay such dividends within such thirty (30) day period, then such dividends will
bear Arrearage Interest, effective beginning on the applicable Annual Dividend
Payment Date, until paid. For purposes of this Section 3(C), "Arrearage
Interest" means simple interest per annum, at the then applicable rate of
interest announced by Chase Manhattan Bank, N.A. from time to time as its prime
rate, on any dividend on shares of Series B Preferred Stock which dividend is
not paid within thirty (30) days following the applicable Annual Dividend
Payment Date.

               (D)    Dividends will be paid by the Corporation on each
outstanding share of Series B Preferred Stock for a minimum of four (4) years
and a maximum of seven (7) years as provided in this Section 3(D).

                      (i)    In the event any shares of Series B Preferred Stock
are converted into Common Stock pursuant to Section 6(A) or 6(B) hereof at any
time after the Issuance Date with respect to such shares pursuant to the Letter
Agreement dated December 21, 2000 (the "First Amendment"), amending the Equity
Line of Credit and Securities Purchase Agreement between the Corporation and
Castle Gate, L.L.C. dated April 8, 1999 (the "Purchase Agreement"), the
Corporation's obligation to pay dividends pursuant to this Section 3 with
respect to such shares shall terminate on the effectiveness of such conversion
in accordance with the terms of this Certificate of Designation; provided,
however, that notwithstanding anything to the contrary in this Section 3(D) in
no event will the Corporation's obligation to pay dividends on such shares,
whether or not such shares have been converted into Common Stock, terminate
before four (4) annual dividend payments (together with any applicable Arrearage
Interest on dividends in arrears) have been made with respect to such shares.

                      (ii)   In the event (a) any shares of Series B Preferred
Stock have not been converted into shares of Common Stock pursuant to Section
6(A) or 6(B) on or prior to the date that is the four-year anniversary of the
Issuance Date with respect to such shares (the "4 Year Anniversary" with respect
to such shares) and (b) on the earlier of the 4 Year Anniversary or any
subsequent annual anniversary of such Issuance Date the average per share
closing price of the Common Stock on the Nasdaq National Market as reported in
the Wall Street Journal (the "Closing Price") for the sixty (60) day period
prior to such 4 Year Anniversary or subsequent annual anniversary, as
applicable, is greater than the product of C x 1.20N (where "C" equals the
Conversion Price applicable to such shares of Series B Preferred Stock and "N"
equals the number of years from the Issuance Date with respect to such shares of
Series B Preferred Stock), then the Corporation's obligation to issue dividends
pursuant to this Section 3 with respect to such shares shall terminate effective
as of such 4 Year Anniversary or subsequent annual anniversary, as applicable,
provided that the Corporation has made at least four (4) annual dividend
payments (together with any applicable Arrearage Interest on dividends in
arrears) with respect to such shares.

                      (iii)  Regardless of whether any shares of Series B
Preferred Stock have been converted into shares of Common Stock in accordance
with this Certificate of Designation, the Corporation's obligation to pay
dividends pursuant to this Section 3 shall terminate fully and be no further
force or effect with respect to any shares of Series B Preferred Stock on the
date that is the seven-year anniversary of the Issuance Date with respect to
such shares; provided that the Corporation has paid all applicable accrued
dividends (together with any applicable Arrearage Interest on dividends in
arrears) in accordance with the terms of this Section 3.

        4.     Liquidation.

               (A)    Subject to the prior and superior rights of the holders of
any shares of any series of Preferred Stock which may from time to time come
into existence ranking prior and superior to the shares of Series B Preferred
Stock with respect to liquidation, in the event of any liquidation, dissolution,
or winding up of the Corporation, whether voluntary or involuntary, all of the
assets and surplus funds of the Corporation legally available for distribution
shall be distributed among the holders of Series A Preferred Stock, Series B
Preferred Stock and Common Stock pro rata based on the number of shares of
Common Stock held by each (assuming full conversion of all such Series B
Preferred Stock in accordance with the terms of this Certificate of
Designation).

               (B)    For purposes of this Section 4, a liquidation, dissolution
or winding up of the Corporation shall be deemed to occur if the Corporation
shall sell, convey, or otherwise dispose of all or substantially all of its
property or business or merge into or consolidate with any other corporation
(other than a wholly-owned subsidiary corporation) or effect any other
transaction or series of related transactions in which more than fifty percent
(50%) of the voting power of the Corporation is disposed of, provided that this
Section 4(b) shall not apply to a merger effected exclusively for the purpose of
changing the domicile of the Corporation; provided further that, if such
transaction or series of transactions results in the holders of the Series B
Preferred Stock receiving securities upon conversion which may then be resold
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "1933

                                      -4-
<PAGE>   5
Act"), then such transactions or series of transactions shall not be as a
liquidation, dissolution change of control or winding up of the Corporation
within the meaning of this Section 4.

               (C)    Whenever the distribution provided for in this Section 4
shall be payable in securities or property other than cash, the value of such
distribution shall be as follows:

                      (i)    Securities not subject to investment letter or
other similar restrictions on free marketability:

                             (A)    If traded on a securities exchanges or The
Nasdaq Stock Market, the value shall be deemed to be average of the closing
prices of the securities on such exchange over the 30-day period ending three
(3) days prior to the closing;

                             (B)    If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid or sale prices
(whichever is applicable) over the 30-day period ending three (3) days prior to
the closing; and

                             (C)    If there is no active public market, the
value shall be the fair market value thereof, as determined in good faith by the
Board of Directors of the Corporation.

                      (ii)   The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a stockholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined in good faith by the Board of Directors of the Corporation.

        5.     Redemption. The Series B Preferred Stock shall not be redeemable.

        6.     Conversion. The holders of Series B Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

               (A)    Optional Conversion. Subject to the limitations on
conversions contained in Section 6(E) below, each share of Series B Preferred
Stock shall be convertible, at the option of the holder thereof, at any time
following the Issuance Date thereof at the office of the Corporation or any
transfer agent for the Preferred Stock, into such number of fully paid and
nonassessable shares of Common Stock as is determined by dividing $1,000.00 by
the applicable Conversion Price for the Series B Preferred Stock (determined as
provided in Section 6(C)).

               (B)    Automatic Conversion. Each share of Series B Preferred
Stock shall automatically be converted into fully paid and nonassessable shares
of Common Stock at the applicable Conversion Price for such share of Series B
Preferred Stock on the earlier of the following: (i) in the event that on the 4
Year Anniversary or any subsequent annual anniversary of the Issuance Date for
such share the Closing Price for the sixty (60) day period prior to such 4 Year
Anniversary or subsequent annual anniversary, as applicable, is greater than the
product of C x 1.30N (where "C" equals the Conversion Price applicable to such
shares of Series B Preferred Stock and "N" equals the number of years from the
Issuance Date with respect to such shares of

                                      -5-
<PAGE>   6
Series B Preferred Stock), and (ii) the date that is the seven-year anniversary
of the Issuance Date applicable to the first share of Series B Preferred Stock
issued pursuant to the First Amendment.

               (C)    Conversion Price. The Conversion Price applicable to a
share of Series B Preferred Stock issued on December 29, 2000 shall be the
average per share closing price of Corixa Common Stock on the Nasdaq National
Market as reported in the Wall Street Journal for the three trading days,
December 26, 2000 through December 28, 2000.

               (D)    Mechanics of Conversion.

                      (i)    In order to effect an optional conversion pursuant
to Section 6(A) above, a holder of Series B Preferred Stock shall fax (or
otherwise deliver) a copy of the fully executed Notice of Conversion attached
hereto as Exhibit A to the Corporation and to the Corporation's transfer agent
with respect to the Common Stock. Upon receipt by the Corporation of the fax
copy of a Notice of Conversion from a holder, the Corporation shall promptly
send, via fax, a confirmation to such holder stating that the Notice of
Conversion has been received, the date upon which the Corporation expects to
deliver the Common Stock issuable upon such conversion and the name and
telephone number of a contact person at the Corporation regarding the
conversion. No later than two (2) business days after receipt of such
confirmation of receipt of Notice of Conversion, the holder shall surrender or
cause to be surrendered to a reputable overnight courier for next business day
delivery (two (2) business day delivery if from outside the United States) to
the Corporation, the certificates representing the shares of Series B Preferred
Stock being converted ("Preferred Stock Certificates") accompanied by duly
executed stock powers and a copy of the Notice of Conversion. The Corporation
shall, as soon as practicable thereafter, issue and deliver at such office to
such holder of the Series B Preferred Stock, or to the nominee or nominees of
such holder, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid. If such holder was a
holder of shares of Series B Preferred Stock on a record date for a dividend
payment corresponding to a particular Annual Dividend Payment Date in accordance
with Section 3(A) and such holder converts any of such shares of Series B
Preferred Stock into Common Stock on or after such Annual Dividend Payment Date,
then such holder will receive the dividend payable by the Corporation on such
shares of Series B Preferred Stock on such Annual Dividend Payment Date in
accordance with the provisions of Section 3. Upon the date of conversion stated
in the Notice of Conversion by a holder of Series B Preferred Stock, (i) the
shares covered thereby (other than the shares, if any, which cannot be issued
because their issuance would exceed the limit set forth in subsection 6(E)(i)
below) shall be deemed converted into shares of Common Stock and (ii) the
holder's rights as a holder of such converted shares of Series B Preferred Stock
shall cease and terminate, excepting only the right to receive certificates for
such shares of Common Stock and to any remedies provided herein or otherwise
available at law or in equity to such holder because of a failure by the
Corporation to comply with the terms of this Certificate of Designation.

                      (ii)   In the event of an automatic conversion pursuant to
Section 6(B) above, the Corporation shall promptly send notification to the
applicable holders of Series B Preferred Stock stating the number of shares of
Series B Preferred Stock that have been automatically converted, the effective
date of such automatic conversion, and an explanation of

                                      -6-
<PAGE>   7
events that led to such automatic conversion. No later than two (2) business
days after receipt of such confirmation of receipt of Notice of Conversion, the
holder shall surrender or cause to be surrendered to a reputable overnight
courier for next business day delivery (two (2) business day delivery if from
outside the United States) to the Corporation, the Preferred Stock Certificates
accompanied by duly executed stock powers and a statement of the name or names
in which the certificate or certificates for shares of Common Stock are to be
issued. The Corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of the Series B Preferred Stock, or to the
nominee or nominees of such holder, a certificate or certificates for the number
of shares of Common Stock to which such holder shall be entitled as aforesaid.
If such holder was a holder of shares of Series B Preferred Stock on a record
date for a dividend payment corresponding to a particular Annual Dividend
Payment Date in accordance with Section 3(A) and such shares are automatically
converted into shares of Common Stock on or after such Annual Dividend Payment
Date, then such holder will receive the dividend payable by the Corporation on
such shares of Series B Preferred Stock on such Annual Dividend Payment Date in
accordance with the provisions of Section 3. Upon the effective date of an
automatic conversion, (i) the shares of Series B Preferred Stock converted
thereby (other than the shares, if any, which cannot be issued because their
issuance would exceed the limit set forth in subsection 6(E)(i) below) shall be
deemed converted into shares of Common Stock and (ii) the holder's rights as a
holder of such converted shares of Series B Preferred Stock shall cease and
terminate, excepting only the right to receive certificates for such shares of
Common Stock and to any remedies provided herein or otherwise available at law
or in equity to such holder because of a failure by the Corporation to comply
with the terms of this Certificate of Designation.

                      (iii)  Unless otherwise provided in this Certificate of
Designation, such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the Series B Preferred
Stock to be converted, and the person or persons entitled to receive the shares
of Common Stock issuable upon such conversion shall be treated for all purposes
as the record holder or holders of such shares of Common Stock as of such date.

               (E)    Limitations on Conversions. The conversion of shares of
Series B Preferred Stock shall be subject to the following limitations (each of
which limitations shall be applied independently):

                      (i)    NASDAQ Rule 4460(i). So long as the Common Stock is
listed for trading on The Nasdaq National Market ("Nasdaq") or an exchange or
quotation system with a rule substantially similar to Rule 4460(i) of the Rules
and Regulations of the National Association of Securities Dealers, Inc. ("Rule
4460(i)"), then notwithstanding anything to the contrary contained in this
Certificate of Designation, the First Amendment, or the Purchase Agreement, if,
at any time, the aggregate number of shares of Common Stock then issued or
issuable upon conversion of the Series B Preferred Stock (including any shares
of Common Stock then issued or issuable upon exercise of outstanding Warrants
(as such term is defined in the Purchase Agreement, as modified by the First
Amendment), and any shares of capital stock or rights to acquire shares of
capital stock issued by the Corporation which are aggregated or integrated with
the shares of Common Stock issuable upon conversion of the Series B Preferred
Stock and the shares of Common Stock issuable upon exercise of outstanding
Warrants for

                                      -7-
<PAGE>   8
purposes of such rule) equals 19.99% of the "Outstanding Common Amount" (as
hereinafter defined), the Series B Preferred Stock shall, from that time
forward, cease to be convertible into shares of Common Stock in accordance with
the terms of this Section 6, until such time as the Corporation (i) has obtained
approval of the issuance of the Common Stock upon conversion of the Series B
Preferred Stock pursuant to the Purchase Agreement by a majority of the total
votes cast on such proposal, in person or by proxy, by the holders of the
then-outstanding Common Stock (not including any shares of Series B Preferred
Stock or any shares of Common Stock held by present or former holders of Series
B Preferred Stock that were issued upon conversion of Series B Preferred Stock)
(the "Stockholder Approval"), or (ii) shall have otherwise obtained permission
to allow such issuances from Nasdaq in accordance with Rule 4460(i). If the
Common Stock is not then listed on Nasdaq or an exchange or quotation system
that has a rule substantially similar to Rule 4460(i) then the limitations set
forth herein shall be inapplicable and of no force and effect. For purposes of
this subsection 6(E)(i), "Outstanding Common Amount" means (i) the number of
shares of the Common Stock outstanding immediately prior to the Initial Closing
(as such term is defined in the Purchase Agreement).

                      (ii)   Minimum Conversion. In no event will the
Corporation be required to effect an optional conversion of any shares of Series
B Preferred Stock pursuant to Section 6(A) unless such conversion will result in
the issuance of that number of shares of Common Stock having an aggregate value
of at least $10,000,000, based upon the applicable Conversion Price for such
shares of Series B Preferred Stock, provided that if the date is more than two
(2) years after the Execution Date (as such term is defined in the Purchase
Agreement) and the aggregate value based upon the applicable Conversion Price of
all the shares of Series B Preferred Stock held by all holder(s) thereof is less
than $10,000,000, the Company will convert all, but not less than all, of such
shares of Series B Preferred Stock at the unanimous election of the holder(s)
thereof in accordance with Section 6(A).

               (F)    Taxes. The Corporation shall pay any and all taxes (other
than transfer taxes or income taxes, if any, payable by the holder) which may be
imposed with respect to the issuance and delivery of the shares of Common Stock
pursuant to conversion of the Series B Preferred Stock.

               (G)    No Fractional Shares. No fractional shares of Common Stock
are to be issued upon the conversion of the Series B Preferred Stock. In lieu
thereof, the Corporation shall pay cash in an amount equal to the product of (x)
the applicable Conversion Price multiplied by (y) the fraction of a share of
Common Stock which would otherwise be issuable by the Corporation.

               (H)    Adjustments To Conversion Prices for Stock Dividends and
for Combinations or Subdivisions of Common Stock. In the event that the
Corporation at any time or from time to time after the Issuance Date of shares
of Series B Preferred Stock shall declare or pay, without consideration, any
dividend on the Common Stock payable in Common Stock or in any right to acquire
Common Stock for no consideration, or shall effect a subdivision of the
outstanding shares of Common Stock into a greater number of shares of Common
Stock (by stock split, reclassification or otherwise than by payment of a
dividend in Common Stock or in any right to acquire Common Stock), or in the
event the outstanding shares of Common Stock

                                      -8-
<PAGE>   9
shall be combined or consolidated, by reclassification or otherwise, into a
lesser number of shares of Common Stock, then the applicable Conversion Price
for such shares of Series B Preferred Stock in effect immediately prior to such
event shall, concurrently with the effectiveness of such event, be
proportionately decreased or increased, as appropriate. In the event that the
Corporation shall declare or pay, without consideration, any dividend on the
Common Stock payable in any right to acquire Common Stock for no consideration
then the Corporation shall be deemed to have made a dividend payable in Common
Stock in an amount of shares equal to the maximum number of shares issuable upon
exercise of such rights to acquire Common Stock.

               (I)    Adjustments for Reclassification and Reorganization. If
the Common Stock issuable upon conversion of shares of Series B Preferred Stock
shall be changed into the same or a different number of shares of any other
class or classes of stock, whether by capital reorganization, reclassification
or otherwise (other than a subdivision or combination of shares provided for in
subsection 6(H) above or a merger or other reorganization referred to in Section
4(B) above), the applicable Conversion Price then in effect for such shares
shall, concurrently with the effectiveness of such reorganization or
reclassification, be proportionately adjusted so that the Series B Preferred
Stock shall be convertible into, in lieu of the number of shares of Common Stock
which the holders would otherwise have been entitled to receive, a number of
shares of such other class or classes of stock equivalent to the number of
shares of Common Stock that would have been subject to receipt by the holders
upon conversion of the Series B Preferred Stock immediately before that change.

               (J)    Purchase Rights. If at any time when any Series B
Preferred Stock is issued and outstanding, the Corporation issues any
convertible securities or rights to purchase stock, warrants, securities or
other property (the "Purchase Rights") pro rata to the record holders of any
class of Common Stock, then the holders of Series B Preferred Stock will be
entitled to acquire, upon the terms applicable to such Purchase Rights, the
aggregate Purchase Rights which such holder could have acquired if such holder
had held the number of shares of Common Stock acquirable upon complete
conversion of the Series B Preferred Stock (without regard to any limitations on
conversion contained herein) immediately before the date on which a record is
taken for the grant, issuance or sale of such Purchase Rights, or, if no such
record is taken, the date as of which the record holders of Common Stock are to
be determined for the grant, issue or sale of such Purchase Rights.

               (K)    No Impairment. The Corporation will not, by amendment of
its Certificate or through any reorganization, recapitalization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the Corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of this Section 6 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Series B Preferred Stock against impairment.

               (L)    Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Price of the Series B Preferred
Stock pursuant to this Section 6, the Corporation, at its expense, shall
promptly compute such adjustment or readjustment in

                                      -9-
<PAGE>   10
accordance with the terms hereof and prepare and furnish to each holder of
Series B Preferred Stock a certificate setting forth such adjustment of
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any affected holder of Series B Preferred Stock, furnish or cause to be
furnished to such holder a like certificate setting forth (A) such adjustment
and readjustment, (B) the Conversion Price at the time in effect, and (C) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of the Series B Preferred
Stock.]

               (M)    Reservation of Stock Issuable Upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock solely for the purpose of effecting the
conversion of the Series B Preferred Stock such number of its shares of Common
Stock as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series B Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect the conversion of all the then outstanding Series B Preferred Stock,
in addition to such other remedies as shall be available to the holder of such
Series B Preferred Stock, the Corporation will take such corporate action as
may, in the opinion of its counsel, be necessary to increase its authorized but
unissued shares of Common Stock to such number of shares as shall be sufficient
for such purposes.

               (N)    Notice. Any notice required by the provisions of this
Section 6 to be given to the holder of Series B Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at his address appearing on the books of the Corporation.

        7.     Voting Rights.

               (A)    Subject to Section 7(D) below, the holder of each share of
Series B Preferred Stock shall have the right to one vote for each share of
Common Stock into which such Series B Preferred Stock could then be converted,
and with respect to such vote, such holder shall have full voting rights and
powers equal to the voting rights and powers of the holders of Common Stock, and
shall be entitled to notice of any stockholders' meeting in accordance with the
bylaws of the Corporation, and shall be entitled to vote, together with holders
of Common Stock, with respect to any question upon which holders of Common Stock
have the right to vote. Fractional votes shall not, however, be permitted and
any fractional voting rights resulting from the above formula (after aggregating
all shares into which shares of Series B Preferred Stock held by each holder
could be converted) shall be rounded to the nearest whole number (with one-half
being rounded upward). Each holder of Common Stock shall be entitled to one (1)
vote for each share of Common Stock held.

               (B)    Except as otherwise provided in Section 8 or by law, the
holders of shares of Series B Preferred Stock, the holders of shares of Series A
Preferred Stock and the holders of shares of Common Stock shall vote together as
one class on all matters submitted to a vote of stockholders of the Corporation.

                                      -10-
<PAGE>   11
               (C)    Except as required by law, holders of Series B Preferred
Stock shall have no special voting rights and their consent shall not be
required (except to the extent they are entitled to vote with holders of Common
Stock as set forth herein) for taking any corporate action.

               (D)    To the extent that the holders of the Series B Preferred
Stock are entitled to vote on a matter with holders of Common Stock, voting
together as one class, or as a separate class in accordance with Section 8
hereof, each share of Series B Preferred Stock shall be entitled to a number of
votes equal to the number of shares of Common Stock into which it is then based
on the applicable Conversion Price; provided, however, in the event the
applicable Conversion Price is deemed to be less than the greater of the
applicable book or market value of a share of Common Stock, as determined in
accordance with Rule 4460(i) and Nasdaq's interpretation thereof as applicable
to the Purchase Agreement and the transactions contemplated thereby (the "Fair
Market Value" of such share of Common Stock), then each share of Series B
Preferred Stock shall be entitled to a number of votes equal to the number of
shares of Common Stock into which it would be convertible in accordance with
such Fair Market Value, without reference to the Conversion Price.

        8.     Protective Provisions. So long as any shares of Series B
Preferred Stock are outstanding, the Corporation shall not without first
obtaining the approval by vote of the holders of at least a majority of the then
outstanding shares of Series B Preferred Stock:

               (i)    alter or change the rights, preferences or privileges of
the Series B Preferred Stock so as to affect adversely the Series B Preferred
Stock;

               (ii)   create any new class or series of capital stock having a
preference over the Series B Preferred Stock as to distribution of assets upon
liquidation, dissolution or winding up of the Corporation; or

               (iii)  increase the authorized number of shares of Series B
Preferred Stock.

               In the event holders of at least a majority of the then
outstanding shares of Series B Preferred Stock agree to allow the Corporation to
alter or change the rights, preferences or privileges of the shares of Series B
Preferred Stock, pursuant to subsection (i) above, so as to affect the Series B
Preferred Stock, then the Corporation will deliver notice of such approved
change to the holders of the Series B Preferred Stock that did not agree to such
alteration or change (the "Dissenting Holders") and Dissenting Holders shall
have the right for a period of thirty (30) days to convert pursuant to the terms
of this Certificate of Designation as they exist prior to such alteration or
change or continue to hold their shares of Series B Preferred Stock.

        9.     Status of Converted Stock. In the event any Series B Preferred
Stock shall be converted pursuant to Section 6 hereof, the shares so converted
shall be cancelled, shall return to the status of authorized but unissued
preferred stock of no designated series, and shall not be issuable by the
Corporation as Preferred Stock.

                                      -11-
<PAGE>   12
        10.    Status as Stockholder. Upon submission of a Notice of Conversion
by a holder of Series B Preferred Stock, the shares covered thereby shall be
deemed converted into shares of Common Stock and the holder's rights as a holder
of such converted shares of Series B Preferred Stock shall cease and terminate,
excepting only the right to receive certificates for such shares of Common Stock
and to any remedies provided herein or otherwise available at law or in equity
to such holder because of a failure by the Corporation to comply with the terms
of this Certificate of Designation.

        11.    Lost or Stolen Certificates. Upon receipt by the Corporation of
evidence of the loss, theft, destruction or mutilation of any Preferred Stock
Certificates representing shares of Series B Preferred Stock, and (in the case
of loss, theft or destruction) of indemnity reasonably satisfactory to the
Corporation, and upon surrender and cancellation of the Preferred Stock
Certificate(s), if mutilated, the Corporation shall execute and deliver new
Preferred Stock Certificate(s) of like tenor and date.

                                      * * *

        RESOLVED FURTHER, that the Chief Executive Officer, the President or any
Vice President, and the Secretary, the Chief Financial Officer, the Treasurer,
or any Assistant Secretary or Assistant Treasurer of the Corporation are each
authorized to execute, verify, and file a Certificate of Designation of Rights
Preferences and Privileges in accordance with Delaware law."
