         Re:      Factoring Agreement, entered into concurrently herewith, by
                  and between Unzipped Apparel LLC, a Delaware limited liability
                  company ("Client") and GE Capital Commercial Services, Inc.
                  ("Factor") (the "Factoring Agreement")

Ladies and Gentlemen:

         Reference is hereby made to the Factoring Agreement and any and all
supplements and agreements entered into in connection therewith (collectively,
the "Factoring Documents") pursuant to which, among other things, Factor has
agreed to factor Client's accounts receivable (the "Factored Accounts") and make
advances to Client against the purchase price of certain Factored Accounts (the
"Advances"). The terms and the provisions of the Factoring Agreement are hereby
incorporated by this reference and except as specifically provided herein all of
the terms and provisions of the Factoring Agreement shall control the
relationship of the parties. All initially capitalized terms used but not
defined herein shall have the meanings attributed to same in the Factoring
Agreement.

         Client's accounts receivable are presently being factored with The CIT
Group/Commercial Services ("CIT"). Pursuant to the terms of the factoring
agreement between Client and CIT the existing factoring relationship with CIT is
scheduled to continue until September 30, 2003. As a result, no Accounts will be
factored and no Advances will be made under the Factoring Agreement (i) until
the Client's factoring relationship with CIT has terminated, (ii) the Client has
provided Factor with a payoff letter/letter of indemnity from CIT, in form and
substance acceptable to Factor in its sole and absolute discretion, and (iii)
there does not then exist an Event of Default under the Factoring Agreement
(collectively, the "Triggering Event").

         During the interim period from the Effective Date through the
Triggering Event, Factor may, in its sole discretion, from time to time at
Client's request provide Client with advances against factor balances owing from
CIT to Client (the "Due From Factor Advances") up to an aggregate principal
amount outstanding at any one time equal to eighty-five percent (85%) of
confirmed factor balances owing from CIT to Client. Factor has the right, at any
time and from time to time, to adjust this advance rate, hold any reserves it
deems necessary as security for the payment and performance of the Obligations,
and to impose other limitations that it deems necessary on Client's ability to
obtain Due From Factor Advances. In no event shall a Due From Factor Advance be
made or (if applicable) a letter of credit be issued if such Due From Factor
Advance or issuance would cause the sum of (a) outstanding Due From Factor
Advances (as determined and calculated in Factor's sole discretion), plus (b)
the aggregate undrawn amounts of all outstanding letters of credit, plus (c) the
aggregate principal amount of Inventory Advances then outstanding under the
Factoring Agreement - Inventory Supplement, between Factor and Client of even
date herewith, at any time exceed $25,000,000.

         Due From Factor Advances may be made available by Factor as provided
herein, provided that: (i) Factor has received satisfactory evidence of
termination of the assignment by Client to Congress of all factor balances owing
to Client by CIT, with the form and substance of same to be acceptable to Factor
in its sole and absolute discretion; (ii) CIT has agreed to the assignment by
Client to Factor of all factor balances pursuant to an assignment of factor
balances agreement executed by and among Client, Factor and CIT, with the form
and substance of same to be acceptable to Factor in its sole and absolute

<PAGE>

discretion; (iii) Client has not (1) obtained any loans or advances from CIT,
(2) obtained CIT's guarantee of any amount due or to become due from Client to
any third party, or (3) opened any letters of credit through CIT; (iv) Client is
not factoring its accounts receivable with any other entity other than CIT; (v)
no event of default has occurred under the factoring agreement between CIT and
Client; (vi) no Event of Default has occurred under the Factoring Agreement; and
(vii) Factor is in receipt of evidence of the amount of the factor balances
owing from CIT to Client, with such evidence to be provided on an ongoing basis
as requested by Factor, with the form and substance of same to be acceptable to
Factor in its sole and absolute discretion.

         All Due From Factor Advances shall be made according the terms and
subject to the conditions of the Factoring Agreement (including, without
limitation, terms and conditions applicable to Advances such as interest
calculations and repayment obligations) and for all purposes shall constitute
"Obligations" under the Factoring Agreement secured by the Collateral. Client
and Factor agree that the terms and provisions of the Factoring Documents which
contemplate the factoring of accounts receivable and the payment of certain
commissions and fees in connection with such factoring activities will be
postponed until such time that the Triggering Event occurs, if ever.

         Assigned factor balances proceeds will be applied against Client's
outstanding Obligations in such order and manner as determined by Factor in its
sole and absolute discretion.

         Upon the occurrence of the Triggering Event, any outstanding Due From
Factor Advances shall become outstanding Advances.

         Notwithstanding anything to the contrary contained in the foregoing, in
the event that the Triggering Event has not occurred on or before September 30,
2003, Factor may, at its option, deem the non-occurrence of the Triggering Event
an Event of Default under the Factoring Agreement entitling Factor to, among
other things, terminate the Factoring Agreement. Upon the termination of the
Factoring Agreement as a result of the failure of the Triggering Event to occur
on or before September 30, 2003, all Due From Factor Advances, plus any and all
accrued interest thereon shall be immediately due and payable, together with any
and all early termination fees and other Obligations that became due and owing
as a result of such termination, as more particularly described in the Factoring
Agreement.

         In consideration of Factor's agreement to provide Due From Factor
Advances, Client agrees to pay: (i) interest on such outstanding Due From Factor
Advances at the interest rate applicable to outstanding Advances under the
Factoring Agreement; (ii) a monthly accommodation fee of $10,000 per month, with
such fee to be prorated for any partial months; and (iii) any other fees set
forth in the Factoring Documents that do not specifically relate to the
factoring of accounts receivable.

         Please acknowledge your agreement to the foregoing by executing where
indicated below.

Sincerely,

GE CAPITAL COMMERCIAL SERVICES, INC.

                                 WITNESSETH THAT

          In consideration of the mutual agreements herein contained, the
parties hereto agree as follows:

                              PRELIMINARY STATEMENT

          The Depositor intends to sell pass-through certificates (collectively,
the "Certificates"), to be issued hereunder in multiple classes, which in the
aggregate will evidence the entire beneficial ownership interest in the Trust
Fund created hereunder. The Certificates will consist of nine classes of
certificates, designated as (i) the Class A-1 Certificates, (ii) the Class A-2
Certificates, (iii) the Class M-1 Certificates, (iv) the Class M-2 Certificates,
(v) the Class B Certificates, (vi) the Class P Certificates, (vii) the Class X-1
Certificates, (viii) the Class X-2 Certificates and (ix) the Class A-R

                                     REMIC 1
                                     -------

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

          (b) In connection with the transfer and assignment set forth in clause

          (iii) the original Assignment of Mortgage, in blank, which assignment

     recording authority evidencing the same; and

          (ix) in the case of the First Mortgage Loans, the original mortgage
     title insurance policy, or if such mortgage title insurance policy has not

     pro forma title insurance policy marked as binding and countersigned by the
     title insurance company or its authorized agent either on its face or by an
     acknowledged closing instruction or escrow letter.

          In the event the Seller delivers to the Trustee certified copies of
any document or instrument set forth in 2.01(b) because of a delay caused by the
public recording office in returning any recorded document, the Seller shall
deliver to the Trustee, within 60 days of the Closing Date, an Officer's
Certificate which shall (i) identify the recorded document, (ii) state that the
recorded document has not been delivered to the Trustee due solely to a delay
caused by the public recording office, and (iii) state the amount of time
generally required by the applicable recording office to record and return a
document submitted for recordation.

          In the event that in connection with any Mortgage Loan the Depositor
cannot deliver (a) the original recorded Mortgage, (b) all interim recorded
assignments or (c) the lender's title policy (together with all riders thereto)
satisfying the requirements set forth above, concurrently with the execution and
delivery hereof because such document or documents have not been returned from
the applicable public recording office in the case of clause (a) or (b) above,
or because the title policy has not been delivered to the Seller or the
Depositor by the applicable title insurer in the case of clause (c) above, the
Depositor shall promptly deliver to the Trustee, in the case of clause (a) or
(b) above, such original Mortgage or such interim assignment, as the case may
be, with evidence of recording indicated thereon upon receipt thereof from the
public recording office, or a copy thereof, certified, if appropriate, by the
relevant recording office and in the case of clause (c) above, if such lender's
title policy is received by the Depositor, upon receipt thereof.

          As promptly as practicable subsequent to such transfer and assignment,
and in any event, within thirty (30) days thereafter, the Trustee shall (at the
Seller's expense) (i) affix the Trustee's name to each Assignment of Mortgage,
as the assignee thereof, (ii) cause such assignment to be in proper form for
recording in the appropriate public office for real property records within
thirty (30) days after receipt thereof and (iii) cause to be delivered for
recording in the appropriate public office for real property records the
assignments of the Mortgages to the Trustee, except that, with respect to any
assignment of a Mortgage as to which the Trustee has not received the
information required to prepare such assignment in recordable form, the
Trustee's obligation to do so and to deliver the same for such recording shall
be as soon as practicable after receipt of such information and in any event
within thirty (30) days after the receipt thereof, and the Trustee need not
cause to be recorded (a) any assignment referred to in clause (iii) above which
relates to a Mortgage Loan in any jurisdiction under the laws of which, as
evidenced by an Opinion of Counsel delivered to the Trustee (at the Depositor's
expense, provided such expense has been previously approved by the Depositor in
writing) within 180 days of the Closing Date, acceptable to the Rating Agencies,
the recordation of such assignment is not necessary to protect the Trustee's and
the Certificateholders' interest in the related Mortgage Loan or (b) if MERS is
identified on the

                                       45
<PAGE>

Mortgage or on a properly recorded assignment of the Mortgage as the mortgagee
of record solely as nominee for the Seller and its successors and assigns.

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

          (c) The Trustee is authorized to appoint any bank or trust company
approved by the Depositor as Custodian of the documents or instruments referred
to in this Section 2.01, and to enter into a Custodial Agreement for such
purpose and any documents delivered thereunder shall be delivered to the
Custodian and any Officer's Certificates delivered with respect thereto shall be
delivered to the Trustee and the Custodian.

          (d) It is the express intent of the parties to this Agreement that the
conveyance of the Mortgage Loans by the Depositor to the Trustee as provided in
this Section 2.01 be, and be construed as, a sale of the Mortgage Loans by the
Depositor to the Trustee. It is, further, not the intention of the parties to
this Agreement that such conveyance be deemed a pledge of the Mortgage Loans by
the Depositor to the Trustee to secure a debt or other obligation of the
Depositor. However, in the event that, notwithstanding the intent of the parties
to this Agreement, the Mortgage Loans are held to be the property of the
Depositor, or if for any other reason this Agreement is held or deemed to create
a security interest in the Mortgage Loans then (a) this Agreement shall also be
deemed to be a security agreement within the meaning of Articles 8 and 9 of the
New York Uniform Commercial Code; (b) the conveyance provided for in this
Section 2.01 shall be deemed to be a grant by the Depositor to the Trustee for
the benefit of the Certificateholders of a security interest in all of the
Depositor's right, title and interest in and to the Mortgage Loans and all
amounts payable to the holders of the Mortgage Loans in accordance with the
terms thereof and all proceeds of the conversion, voluntary or involuntary, of
the foregoing into cash, instruments, securities or other property, including
without limitation all amounts, other than investment earnings, from time to
time held or invested in the Certificate Account, whether in the form of cash,
instruments, securities or other property; (c) the possession by the Trustee or
any Custodian of such items of property and such other items of property as
constitute instruments, money, negotiable documents or chattel paper shall be
deemed to be "in possession by the secured party" for purposes of perfecting the
security interest pursuant to Section 9-305 of the New York Uniform Commercial
Code; and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the Trustee
for the

                                       46
<PAGE>

benefit of the Certificateholders for the purpose of perfecting such security
interest under applicable law (except that nothing in this clause (e) shall
cause any person to be deemed to be an agent of the Trustee for any purpose
other than for perfection of such security interests unless, and then only to
the extent, expressly appointed and authorized by the Trustee in writing). The
Depositor and the Trustee, upon directions from the Depositor, shall, to the
extent consistent with this Agreement, take such actions as may be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
Mortgage Loans, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and will be maintained
as such throughout the term of this Agreement.

          (e) The Depositor hereby sells, transfers, assigns, sets over and
otherwise conveys to the Trustee in trust for the benefit of the
Certificateholders, without recourse, all right, title and interest in such
Subsequent Mortgage Loans (which does not include servicing rights), including
all interest and principal due on or with respect to such Subsequent Mortgage
Loans on or after the related Subsequent Transfer Date and all interest and
principal payments on such Subsequent Mortgage Loans received prior to the
Subsequent Transfer Date in respect of installments of interest and principal
due thereafter, but not including principal and interest due on such Subsequent
Mortgage Loans prior to the related Subsequent Transfer Date, any insurance
policies in respect of such Subsequent Mortgage Loans and all proceeds of any of
the foregoing.

          (f) Upon one Business Day's prior written notice to the Trustee, the
Servicer and the Rating Agencies, on any Business Day during the Pre-Funding
Period designated by the Depositor, the Depositor, DLJMC, the Servicer and the
Trustee shall complete, execute and deliver a Subsequent Transfer Agreement so
long as no Rating Agency has provided notice that the execution and delivery of
such Subsequent Transfer Agreement will result in a reduction or withdrawal of
the ratings assigned to the Certificates.

     with respect to a Subsequent Mortgage Loan, the obligation under Section
     2.03(f) of this Agreement of the Seller to cure, repurchase or replace such

     Depositor or the Trustee;

          (ii) the Trustee and the Rating Agencies are provided with an Opinion

          SECTION 2.02 Acceptance by the Trustee.

          The Trustee acknowledges receipt by the Custodian of the documents
identified in the Initial Certification in the form annexed hereto as Exhibit G
and declares that the Custodian on its behalf hold and will hold the documents
delivered to the Custodian constituting the Mortgage Files, and that it or the
Custodian holds or will hold such other assets as are included in the Trust
Fund, in trust for the exclusive use and benefit of all present and future
Certificateholders. The Trustee acknowledges that it will maintain possession
through the Custodian of the Mortgage Notes in the State of Texas or the State
of Illinois, as directed by the Seller, unless otherwise permitted by the Rating
Agencies.

                                       49
<PAGE>

          The Custodian agrees to execute and deliver on the Closing Date to the
Depositor, the Seller, the Trustee and the Servicer an Initial Certification in
the form annexed hereto as Exhibit G. Based on its review and examination, and
only as to the documents identified in such Initial Certification, the Custodian
will acknowledge that such documents appear regular on their face and relate to
such Mortgage Loan. Neither the Trustee nor the Custodian shall be under any
duty or obligation to inspect, review or examine said documents, instruments,
certificates or other papers to determine that the same are genuine, enforceable
or appropriate for the represented purpose or that they have actually been
recorded in the real estate records or that they are other than what they
purport to be on their face.

          Not later than 90 days after the Closing Date, the Custodian is
required to deliver to the Depositor, the Seller, the Trustee and the Servicer a
Final Certification in the form annexed hereto as Exhibit H, with any applicable
exceptions noted thereon.

          If, in the course of such review, the Custodian finds any document
constituting a part of a Mortgage File which does not meet the requirements of
Section 2.01, the Custodian will list such as an exception in the Final
Certification; provided, however, that neither the Trustee nor the Custodian
shall make any determination as to whether (i) any endorsement is sufficient to
transfer all right, title and interest of the party so endorsing, as noteholder
or assignee thereof, in and to that Mortgage Note or (ii) any assignment is in
recordable form or is sufficient to effect the assignment of and transfer to the
assignee thereof under the mortgage to which the assignment relates.

          The Seller shall promptly correct or cure such defect within 120 days
from the date it was so notified of such defect and, if the Seller does not
correct or cure such defect within such period, the Seller shall either (a)
substitute for the related Mortgage Loan a Qualified Substitute Mortgage Loan,
which substitution shall be accomplished in the manner and subject to the
conditions set forth in Section 2.03, or (b) purchase such Mortgage Loan from
the Trustee within 120 days from the date the Seller was notified of such defect
in writing at the Repurchase Price of such Mortgage Loan; provided, however,
that in no event shall such substitution or repurchase occur more than 540 days
from the Closing Date, except that if the substitution or repurchase of a
Mortgage Loan pursuant to this provision is required by reason of a delay in
delivery of any documents by the appropriate recording office, then such
substitution or repurchase shall occur within 720 days from the Closing Date;
and further provided, that the Seller shall have no liability for recording any
Assignment of Mortgage in favor of the Trustee or for the Trustee's failure to
record such Assignment of Mortgage, and the Seller shall not be obligated to
repurchase or cure any Mortgage Loan solely as a result of the Trustee's failure
to record such Assignment of Mortgage. The Trustee shall deliver written notice
to each Rating Agency within 360 days from the Closing Date indicating each
Mortgage Loan (a) the Assignment of Mortgage which has not been returned by the
appropriate recording office or (b) as to which there is a dispute as to
location or status of such Mortgage Loan. Such notice shall be delivered every
90 days thereafter until the Assignment of Mortgage for the related Mortgage
Loan is returned to the Trustee or the dispute as to location or status has been
resolved. Any such substitution pursuant to (a) above shall not be effected
prior to the delivery to the Trustee of the Opinion of Counsel required by
Section 2.05 hereof, if any, and any substitution pursuant to (a) above shall
not be effected prior to the additional delivery to the Trustee of a Request for
Release substantially in the form of Exhibit M. No substitution is permitted to
be made in any calendar month after the Determination Date for such month. The
Repurchase Price for any such

                                       50
<PAGE>

Mortgage Loan shall be deposited by the Seller in the Certificate Account on or
prior to the Business Day immediately preceding such Distribution Date in the
month following the month of repurchase and, upon receipt of such deposit and
certification with respect thereto in the form of Exhibit M hereto, the Trustee
shall release the related Mortgage File to the Seller and shall execute and
deliver at such entity's request such instruments of transfer or assignment
prepared by such entity, in each case without recourse, as shall be necessary to
vest in such entity, or a designee, the Trustee's interest in any Mortgage Loan
released pursuant hereto. In furtherance of the foregoing, if the Seller is not
a member of MERS and repurchases a Mortgage Loan which is registered on the
MERS(R) System, the Seller, at its own expense and without any right of
reimbursement, shall cause MERS to execute and deliver an assignment of the
Mortgage in recordable form to transfer the Mortgage from MERS to the Seller and
shall cause such Mortgage to be removed from registration on the MERS(R) System
in accordance with MERS' rules and regulations.

          Pursuant to the Custodial Agreement, the Custodian is required to
execute and deliver on the Subsequent Transfer Date to the Depositor, the
Seller, the Trustee and the Servicer an Initial Certification in the form
annexed hereto as Exhibit G. Based on its review and examination, and only as to
the documents identified in such Initial Certification, the Custodian shall
acknowledge that such documents appear regular on their face and relate to such
Subsequent Mortgage Loan. Neither the Trustee nor the Custodian shall be under a
duty or obligation to inspect, review or examine said documents, instruments,
certificates or other papers to determine that the same are genuine, enforceable
or appropriate for the represented purpose or that they have actually been
recorded in the real estate records or that they are other than what they
purport to be on their face.

          Pursuant to the Custodial Agreement, not later than 90 days after the
end of the Pre- Funding Period, the Custodian is required to deliver to the
Depositor, the Seller, the Trustee and the related Servicer a Final
Certification with respect to the Subsequent Mortgage Loans in the form annexed
hereto as Exhibit H with any applicable exceptions noted thereon.

          If, in the course of such review of the Mortgage Files relating to the
Subsequent Mortgage Loans, the Custodian finds any document constituting a part
of a Mortgage File which does not meet the requirements of Section 2.01,
pursuant to the Custodial Agreement, the Custodian will be required to list such
as an exception in the Final Certification; provided, however that neither the
Trustee nor the Custodian shall make any determination as to whether (i) any
endorsement is sufficient to transfer all right, title and interest of the party
so endorsing, as noteholder or assignee thereof, in and to that Mortgage Note or
(ii) any assignment is in recordable form or is sufficient to effect the
assignment of and transfer to the assignee thereof under the mortgage to which
the assignment relates. The Seller shall cure any such defect or repurchase or
substitute for any such Mortgage Loan in accordance with Section 2.02(a).

          It is understood and agreed that the obligation of the Seller to cure,
substitute for or to repurchase any Mortgage Loan which does not meet the
requirements of Section 2.01 shall constitute the sole remedy respecting such
defect available to the Trustee, the Depositor and any Certificateholder against
the Seller.

          The Trustee shall pay to the Custodian from time to time reasonable
compensation for all services rendered by it hereunder or under the Custodial
Agreement, and the Trustee shall pay

                                       51
<PAGE>

or reimburse the Custodian upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Custodian in accordance with
any of the provisions of this Agreement or the Custodial Agreement, except any
such expense, disbursement or advance as may arise from its negligence or bad
faith.

          SECTION 2.03 Representations and Warranties of the Seller and
Servicer.

          (a) The Seller hereby makes the representations and warranties
applicable to it set forth in Schedule II hereto, and by this reference
incorporated herein, to the Depositor and the Trustee, as of the Closing Date,
or if so specified therein, as of the Cut-off Date or such other date as may be
specified.

          (b) Wilshire, in its capacity as Servicer, hereby makes the
representations and warranties applicable to it set forth in Schedule III
hereto, and by this reference incorporated herein, to the Depositor and the
Trustee, as of the Closing Date, or if so specified therein, as of the Cut Date
or such other date as may be specified.

          (c) Wilshire, in its capacity as Servicer, will use its reasonable
efforts to become a member of MERS in good standing, and will comply in all
material respects with the rules and procedures of MERS in connection with the
servicing of the Mortgage Loans that are registered with MERS.

          (d) The Seller hereby makes the representations and warranties set
forth in Schedule IV as applicable hereto, and by this reference incorporated
herein, to the Trustee, as of the Closing Date, or the Subsequent Transfer Date,
as applicable, or if so specified therein, as of the Cut- off Date or such other
date as may be specified.

          (e) Upon discovery by any of the parties hereto of a breach of a
representation or warranty made pursuant to Section 2.03(d) that materially and
adversely affects the interests of the Certificateholders in any Mortgage Loan,
the party discovering such breach shall give prompt notice thereof to the other
parties. The Seller hereby covenants that within 120 days of the earlier of its
discovery or its receipt of written notice from any party of a breach of any
representation or warranty made by it pursuant to Section 2.03(d) which
materially and adversely affects the interests of the Certificateholders in any
Mortgage Loan sold by the Seller to the Depositor, it shall cure such breach in
all material respects, and if such breach is not so cured, shall, (i) if such
120-day period expires prior to the second anniversary of the Closing Date,
remove such Mortgage Loan (a "Deleted Mortgage Loan") from the Trust Fund and
substitute in its place a Qualified Substitute Mortgage Loan, in the manner and
subject to the conditions set forth in this Section; or (ii) repurchase the
affected Mortgage Loan from the Trustee at the Repurchase Price in the manner
set forth below; provided, however, that any such substitution pursuant to (i)
above shall not be effected prior to the delivery to the Trustee of the Opinion
of Counsel required by Section 2.05 hereof, if any, and any such substitution
pursuant to (i) above shall not be effected prior to the additional delivery to
the Trustee of a Request for Release substantially in the form of Exhibit M and
the Mortgage File for any such Qualified Substitute Mortgage Loan. The Seller
shall promptly reimburse the Trustee for any actual out-of-pocket expenses
reasonably incurred by the Trustee in respect of enforcing the remedies for such
breach. With respect to any representation and warranties described in this
Section

                                       52
<PAGE>

which are made to the best of a Seller's knowledge if it is discovered by the
Depositor, the Seller or the Trustee that the substance of such representation
and warranty is inaccurate and such inaccuracy materially and adversely affects
the value of the related Mortgage Loan or the interests of the
Certificateholders therein, notwithstanding the Seller's lack of knowledge with
respect to the substance of such representation or warranty, such inaccuracy
shall be deemed a breach of the applicable representation or warranty.

          With respect to any Qualified Substitute Mortgage Loan or Loans, the
Seller shall deliver to the Trustee for the benefit of the Certificateholders
the Mortgage Note, the Mortgage, the related assignment of the Mortgage, and
such other documents and agreements as are required by Section 2.01(b), with the
Mortgage Note endorsed and the Mortgage assigned as required by Section 2.01. No
substitution is permitted to be made in any calendar month after the
Determination Date for such month. Scheduled Payments due with respect to
Qualified Substitute Mortgage Loans in the month of substitution shall not be
part of the Trust Fund and will be retained by the Seller on the next succeeding
Distribution Date. For the month of substitution, distributions to
Certificateholders will include the monthly payment due on any Deleted Mortgage
Loan for such month and thereafter the Seller shall be entitled to retain all
amounts received in respect of such Deleted Mortgage Loan. The Seller shall
amend the Mortgage Loan Schedule for the benefit of the Certificateholders to
reflect the removal of such Deleted Mortgage Loan and the substitution of the
Qualified Substitute Mortgage Loan or Loans and the Seller shall deliver the
amended Mortgage Loan Schedule to the Trustee. Upon such substitution, the
Qualified Substitute Mortgage Loan or Loans shall be subject to the terms of
this Agreement in all respects, and the Seller shall be deemed to have made with
respect to such Qualified Substitute Mortgage Loan or Loans, as of the date of
substitution, the representations and warranties made pursuant to Section
2.03(d) with respect to such Mortgage Loan. Upon any such substitution and the
deposit to the Certificate Account of the amount required to be deposited
therein in connection with such substitution as described in the following
paragraph, the Trustee shall release the Mortgage File held for the benefit of
the Certificateholders relating to such Deleted Mortgage Loan to the Seller and
shall execute and deliver at the Seller's direction such instruments of transfer
or assignment prepared by the Seller, in each case without recourse, as shall be
necessary to vest title in the Seller, or its designee, the Trustee's interest
in any Deleted Mortgage Loan substituted for pursuant to this Section 2.03.

          For any month in which the Seller substitutes one or more Qualified
Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Trustee
shall determine the amount (if any) by which the aggregate principal balance of
all such Qualified Substitute Mortgage Loans as of the date of substitution is
less than the aggregate Stated Principal Balance of all such Deleted Mortgage
Loans (after application of the scheduled principal portion of the monthly
payments due in the month of substitution). The amount of such shortage (the
"Substitution Adjustment Amount") plus an amount equal to the aggregate of any
unreimbursed Advances with respect to such Deleted Mortgage Loans shall be
deposited in the Certificate Account by the Seller on or before the Business Day
immediately preceding the Distribution Date in the month succeeding the calendar
month during which the related Mortgage Loan became required to be repurchased
or replaced hereunder.

          In the event that the Seller shall have repurchased a Mortgage Loan,
the Repurchase Price therefor shall be deposited in the Certificate Account on
or before the Business Day immediately preceding the Distribution Date in the
month following the month during which the

                                       53
<PAGE>

Seller became obligated hereunder to repurchase or replace such Mortgage Loan
and upon such deposit of the Repurchase Price, the delivery of the Opinion of
Counsel if required by Section 2.05 and receipt of a Request for Release in the
form of Exhibit M hereto, the Trustee shall release the related Mortgage File
held for the benefit of the Certificateholders to such Person, and the Trustee
shall execute and deliver at such Person's direction such instruments of
transfer or assignment prepared by such Person, in each case without recourse,
as shall be necessary to transfer title from the Trustee. It is understood and
agreed that the obligation under this Agreement of any Person to cure,
repurchase or substitute any Mortgage Loan as to which a breach has occurred and
is continuing shall constitute the sole remedy against such Persons respecting
such breach available to Certificateholders, the Depositor or the Trustee on
their behalf.

          The representations and warranties made pursuant to this Section 2.03
shall survive delivery of the respective Mortgage Files to the Trustee for the
benefit of the Certificateholders.

          SECTION 2.04 Representations and Warranties of the Depositor as to the
                       Mortgage Loans.

          The Depositor hereby represents and warrants to the Trustee with
respect to the Mortgage Loans that, as of the Closing Date, assuming good title
has been conveyed to the Depositor, the Depositor had good title to the Mortgage
Loans and Mortgage Notes, and did not encumber the Mortgage Loans during its
period of ownership thereof, other than as contemplated by the Agreement.

          It is understood and agreed that the representations and warranties
set forth in this Section 2.04 shall survive delivery of the Mortgage Files to
the Trustee.

          SECTION 2.05 Delivery of Opinion of Counsel in Connection with
                       Substitutions.

          Notwithstanding any contrary provision of this Agreement, no
substitution pursuant to Section 2.02 shall be made more than 120 days after the
Closing Date unless the Seller delivers to the Trustee an Opinion of Counsel,
which Opinion of Counsel shall not be at the expense of either the Trustee or
the Trust Fund, addressed to the Trustee, to the effect that such substitution
will not (i) result in the imposition of the tax on "prohibited transactions" on
the Trust Fund or contributions after the Startup Date, as defined in Sections
860F(a)(2) and 860G(d) of the Code, respectively, or (ii) cause any REMIC
created hereunder to fail to qualify as a REMIC at any time that any
Certificates are outstanding.

          SECTION 2.06 Execution and Delivery of Certificates.

          The Trustee (or the Custodian) acknowledges receipt of the items
described in Section 2.02 of this Agreement and the documents identified in the
Initial Certification in the form annexed hereto as Exhibit G and, concurrently
with such receipt, has executed and delivered to or upon the order of the
Depositor, the Certificates in authorized denominations evidencing directly or
indirectly the entire ownership of the Trust Fund. The Trustee agrees to hold
the Trust Fund and exercise the rights referred to above for the benefit of all
present and future Holders of the Certificates and to

                                       54
<PAGE>

perform the duties set forth in this Agreement to the best of its ability, to
the end that the interests of the Holders of the Certificates may be adequately
and effectively protected.

          SECTION 2.07 REMIC Matters.

          The Preliminary Statement sets forth the designations and "latest
possible maturity date" for federal income tax purposes of all interests created
hereby. The "Startup Day" for purposes of the REMIC Provisions shall be the
Closing Date. The REMIC 1 Regular Interests shall be designated as the "regular
interests" in REMIC 1. The REMIC 2 Regular Interests shall be designated as the
"regular interests" in REMIC 2. The Class A-1, Class A-2, Class M-1, Class M2,
Class B, Class P and Class X-1 Certificates shall be designated as the "regular
interests" in REMIC 3. The Class A-R Certificates will represent beneficial
ownership of three residual interests, each of which will constitute the sole
class of residual interests in each of REMIC 1, REMIC 2 and REMIC 3. The Trustee
shall not permit the creation of any "interests" (within the meaning of Section
860G of the Code) in REMIC 1, REMIC 2 or REMIC 3 other than the Certificates or
the Uncertificated REMIC Regular Interests. The "tax matters person" with
respect to each of REMIC 1, REMIC 2 and REMIC 3 shall be the Holder of the Class
A-R Certificate at any time holding the largest Percentage Interest thereof in
the manner provided under Treasury regulations section 1.860F-4(d) and Treasury
regulations section 301.6231(a)(7)-1. The fiscal year for each REMIC shall be
the calendar year.

          SECTION 2.08 Covenants of the Servicer.

          The Servicer hereby covenants to the Depositor and the Trustee that no
written information, certificate of an officer, statement furnished in writing
or written report prepared by the Servicer and delivered to the Depositor, any
affiliate of the Depositor or the Trustee and prepared by the Servicer pursuant
to this Agreement will contain any untrue statement of a material fact.

          SECTION 2.09 Conveyance of REMIC Regular Interests and Acceptance of
                       REMIC 1 and REMIC 2 by the Trustee; Issuance of
                       Certificates.

          (a) The Depositor, concurrently with the execution and delivery
hereof, does hereby transfer, assign, set over and otherwise convey in trust to
the Trustee without recourse all the right, title and interest of the Depositor
in and to the REMIC 1 Regular Interests for the benefit of the Holder of the
REMIC 2 Regular Interests and the Holders of the Class R-2 Interest. The Trustee
acknowledges receipt of the REMIC 1 Regular Interests (each of which is
uncertificated) and declares that it holds and will hold the same in trust for
the exclusive use and benefit of the Holders of the REMIC 2 Regular Interests
and Holder of the Class R-2 Interest. The interests evidenced by the Class R-2
Interest, together with the REMIC 2 Regular Interests, constitute the entire
beneficial ownership interest in REMIC 2.

          (b) The Depositor, concurrently with the execution and delivery
hereof, does hereby transfer, assign, set over and otherwise convey in trust to
the Trustee without recourse all the right, title and interest of the Depositor
in and to the REMIC 2 Regular Interests for the benefit of the holders of the
Regular Certificates and the Class R-3 Interest. The Trustee acknowledges
receipt of the REMIC 2 Regular Interests (each of which is uncertificated) and
declares that it holds and will

                                       55
<PAGE>

hold the same in trust for the exclusive use and benefit of the holders of the
Regular Certificates and the Class R-3 Interest. The interests evidenced by the
Class R-3 Interest, together with the Regular Certificates, constitute the
entire beneficial ownership interest in REMIC 3.

          (c) In exchange for the REMIC 2 Regular Interests and, concurrently
with the assignment to the Trustee thereof, pursuant to the written request of
the Depositor executed by an officer of the Depositor, the Trustee has executed,
authenticated and delivered to or upon the order of the Depositor, the Regular
Certificates in authorized denominations evidencing (together with the Class R-3
Interest) the entire beneficial ownership interest in REMIC 3.

          (d) Concurrently with (i) the assignment and delivery to the Trustee
of REMIC 1 (including the Residual Interest therein represented by the Class R-1
Interest) and the acceptance by the Trustee thereof, pursuant to Section 2.01,
Section 2.02 and Section 2.09(a); (ii) the assignment and delivery to the
Trustee of REMIC 2 (including the Residual Interest therein represented by the
Class R-2 Interest) and the acceptance by the Trustee thereof, pursuant to
Section 2.09(b) and (iii) the assignment and delivery to the Trustee of REMIC 3
(including the Residual Interest therein represented by the Class R-3 Interest)
and the acceptance by the Trustee thereof, pursuant to Section 2.09(c) the
Trustee, pursuant to the written request of the Depositor executed by an officer
of the Depositor, has executed, authenticated and delivered to or upon the order
of the Depositor, the Class A-R Certificates in authorized denominations
evidencing the Class R-1 Interest, the Class R-2 Interest and the Class R-3
Interest.

                                   ARTICLE III

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

          SECTION 3.01 Servicer to Service Mortgage Loans.

          For and on behalf of the Certificateholders, the Servicer shall
service and administer the Mortgage Loans in accordance with the terms of this
Agreement and with Accepted Servicing Practices. Notwithstanding anything in
this Agreement, any Servicing Agreement or the Credit Risk Management Agreement
to the contrary, the Servicer shall have no duty or obligation to enforce the
Credit Risk Management Agreement or to supervise, monitor or oversee the
activities of the Credit Risk Manager under the Credit Risk Management Agreement
with respect to any action taken or not taken by the Servicer, pursuant to a
recommendation of the Credit Risk Manager. In connection with such servicing and
administration, the Servicer shall have full power and authority, acting alone
and/or through Subservicers 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 (i) to execute and deliver,
on behalf of the Certificateholders and the Trustee, customary consents or
waivers and other instruments and documents, (ii) to consent to transfers of any
Mortgaged Property and assumptions of the Mortgage Notes and related Mortgages
(but only in the manner provided in this Agreement), (iii) to collect any
Insurance Proceeds and other Liquidation Proceeds, and (iv) to effectuate
foreclosure or other conversion of the ownership of the Mortgaged Property
securing any Mortgage Loan; provided that the Servicer shall not take any action
that is materially inconsistent with or materially prejudices the interests of
the Trust Fund or the Certificateholders in any Mortgage Loan or the rights and
interests of the Depositor, the Trustee or the Certificateholders under this
Agreement unless such action is specifically called for by the terms hereof. The
Trustee will provide a limited power of attorney to the Servicer, prepared by
the Servicer and reasonably acceptable to the Trustee, to permit the Servicer to
act on behalf of the Trustee under this Agreement. The Servicer hereby
indemnifies the Trustee for all costs and expenses incurred by the Trustee in
connection with the negligent or willful misuse of such power of attorney. The
Servicer shall represent and protect the interests of the Trust Fund in the same
manner as it protects its own interests in mortgage loans in its own portfolio
in any claim, proceeding or litigation regarding a Mortgage Loan. The Servicer
further is hereby authorized and empowered in its own name or in the name of the
Subservicer, when the Servicer or the Subservicer, as the case may be, believes
it is appropriate in its best judgment to register any Mortgage Loan on the
MERS(R) System, or cause the removal from the registration of any Mortgage Loan
on the MERS(R) System, to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of assignment and
other comparable instruments with respect to such assignment or re-recording of
a Mortgage in the name of MERS, solely as nominee for the Trustee and its
successors and assigns. Any reasonable expenses incurred in connection with the
actions described in the preceding sentence or as a result of MERS discontinuing
or becoming unable to continue operations in connection with the MERS(R) System,
shall be reimbursable by the Trust Fund to the Servicer. Notwithstanding the
foregoing, subject to Section 3.05(a), the Servicer shall not make or permit any
modification, waiver or amendment of any Mortgage Loan that would both
constitute a sale or exchange of such Mortgage Loan within the meaning of
Section 1001 of the Code and any proposed, temporary or final

                                       57
<PAGE>

regulations promulgated thereunder (other than in connection with a proposed
conveyance or assumption of such Mortgage Loan that is treated as a Principal
Prepayment in Full pursuant to Section 3.10 hereof) which would cause any of
REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC. Without limiting the
generality of the foregoing, the Servicer, in its own name or in the name of the
Depositor and the Trustee, is hereby authorized and empowered by the Depositor
and the Trustee, when the Servicer believes it appropriate in its reasonable
judgment, to execute and deliver, on behalf of the Trustee, the Depositor, the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation, or of partial or full release or discharge and all other
comparable instruments, with respect to the Mortgage Loans, and with respect to
the Mortgaged Properties held for the benefit of the Certificateholders. The
Servicer shall prepare and deliver to the Depositor and/or the Trustee such
documents requiring execution and delivery by either or both of them as are
necessary or appropriate to enable the Servicer to service and administer the
Mortgage Loans to the extent that the Servicer is not permitted to execute and
deliver such documents pursuant to the preceding sentence. Upon receipt of such
documents and a written request signed by an authorized officer, the Depositor
and/or the Trustee shall execute such documents and deliver them to the
Servicer.

          In accordance with the standards of the preceding paragraph, the
Servicer shall advance or cause to be advanced funds as necessary for the
purpose of effecting the payment of taxes and assessments on any Mortgaged
Property (to the extent the Servicer has been notified that such taxes or
assessments have not paid by the related Mortgagor or the owner or the servicer
of the related First Mortgage Loan), which advances shall be reimbursable in the
first instance from related collections from the Mortgagors pursuant to Section
3.06, and further as provided in Section 3.08; provided, however, that the
Servicer shall be required to advance only to the extent that such advances, in
the good faith judgment of the Servicer, will be recoverable by the Servicer out
of Insurance Proceeds, Liquidation Proceeds, or otherwise out of the proceeds of
the related Mortgage Loan; and provided, further, that such payments shall be
advanced when the tax, premium or other cost for which payment is intended is
due to the extent the Servicer has been notified that such payment has not been
made at least five (5) Business Days prior to the due date. The costs incurred
by the Servicer, if any, in effecting the timely payments of taxes and
assessments on the Mortgaged Properties and related insurance premiums shall
not, for the purpose of calculating monthly distributions to the
Certificateholders, be added to the Stated Principal Balances of the related
Mortgage Loans, notwithstanding that the terms of such Mortgage Loans so permit.

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

          If the Mortgage relating to a Mortgage Loan had a lien senior to the
Mortgage Loan on the related Mortgaged Property as of the Cut-off Date, then the
Servicer, in such capacity, may consent to the refinancing of the prior senior
lien, provided that the following requirements are met:

                                       58
<PAGE>

          (i) the resulting Combined Loan-to-Value Ratio of such Mortgage Loan
     is no higher than the Combined Loan-to-Value Ratio prior to such
     refinancing; and

          (ii) the interest rate, or, in the case of an adjustable rate existing
     senior lien, the maximum interest rate, for the loan evidencing the
     refinanced senior lien is no more than 2.0% higher than the interest rate
     or the maximum interest rate, as the case may be, on the loan evidencing
     the existing senior lien immediately prior to the date of such refinancing;
     and

          (iii) the loan evidencing the refinanced senior lien is not subject to
     negative amortization.

          SECTION 3.02 Subservicing; Enforcement of the Obligations of
                       Subservicers.

          (a) The Mortgage Loans may be subserviced by a Subservicer on behalf
of the Servicer in accordance with the servicing provisions of this Agreement,
provided that the Subservicer is an approved Fannie Mae or Freddie Mac
seller/servicer in good standing. The Servicer may perform any of its servicing
responsibilities hereunder or may cause the Subservicer to perform any such
servicing responsibilities on its behalf, but the use by the Servicer of the
Subservicer shall not release the Servicer from any of its obligations hereunder
and the Servicer shall remain responsible hereunder for all acts and omissions
of the Subservicer as fully as if such acts and omissions were those of the
Servicer. The Servicer shall pay all fees and expenses of any Subservicer
engaged by the Servicer from its own funds.

          Notwithstanding the foregoing, the Servicer shall be entitled to
outsource one or more separate servicing functions to a Person (each, an
"Outsourcer") that does not meet the eligibility requirements for a Subservicer,
so long as such outsourcing does not constitute the delegation of the Servicer's
obligation to perform all or substantially all of the servicing of the related
Mortgage Loans to such Outsourcer. In such event, the use by the Servicer of any
such Outsourcer shall not release the Servicer from any of its obligations
hereunder and the Servicer shall remain responsible hereunder for all acts and
omissions of such Outsourcer as fully as if such acts and omissions were those
of the Servicer, and the Servicer shall pay all fees and expenses of the
Outsourcer from the Servicer's own funds.

          (b) At the cost and expense of the Servicer, without any right of
reimbursement from the Depositor, Trustee, the Trust Fund, or the Collection
Account, the Servicer shall be entitled to terminate the rights and
responsibilities of its Subservicer and arrange for any servicing
responsibilities to be performed by a successor Subservicer meeting the
requirements set forth in Section 3.02(a), provided, however, that nothing
contained herein shall be deemed to prevent or prohibit the Servicer, at the
Servicer's option, from electing to service the related Mortgage Loans itself.
In the event that the Servicer's responsibilities and duties under this
Agreement are terminated pursuant to Section 7.01, and if requested to do so by
the Trustee, the Servicer shall at its own cost and expense terminate the rights
and responsibilities of its Subservicer as soon as is reasonably possible. The
Servicer shall pay all fees, expenses or penalties necessary in order to
terminate the

                                       59
<PAGE>

rights and responsibilities of its Subservicer from the Servicer's own funds
without any right of reimbursement from the Depositor, Trustee, the Trust Fund,
or the Collection Account.

          (c) Notwithstanding any of the provisions of this Agreement relating
to agreements or arrangements between the Servicer and its Subservicer, the
Servicer and its Outsourcer, or any reference herein to actions taken through
the Subservicer, the Outsourcer, or otherwise, the Servicer shall not be
relieved of its obligations to the Depositor, Trustee or Certificateholders and
shall be obligated to the same extent and under the same terms and conditions as
if it alone were servicing and administering the related Mortgage Loans. The
Servicer shall be entitled to enter into an agreement with its Subservicer and
Outsourcer for indemnification of the Servicer or Outsourcer, as applicable, by
such Subservicer and nothing contained in this Agreement shall be deemed to
limit or modify such indemnification.

          For purposes of this Agreement, the Servicer shall be deemed to have
received any collections, recoveries or payments with respect to the related
Mortgage Loans that are received by a related Subservicer or Outsourcer, as
applicable, regardless of whether such payments are remitted by the Subservicer
or Outsourcer, as applicable, to the Servicer.

          Any Subservicing Agreement and any other transactions or services
relating to the Mortgage Loans involving a Subservicer or an Outsourcer shall be
deemed to be between the Subservicer or an Outsourcer, and the Servicer alone,
and the Depositor and the Trustee shall have no obligations, duties or
liabilities with respect to a Subservicer including no obligation, duty or
liability of the Depositor and Trustee or the Trust Fund to pay a Subservicer's
fees and expenses.

          SECTION 3.03 [Reserved].

          SECTION 3.04 Trustee to Act as Servicer.

          (a) In the event that the Servicer shall for any reason no longer be
the Servicer hereunder (including by reason of an Event of Default), the Trustee
or its successor shall thereupon assume all of the rights and obligations of the
Servicer hereunder arising thereafter (except that the Trustee shall not be (i)
liable for losses of the Servicer pursuant to Section 3.09 hereof or any acts or
omissions of the related predecessor Servicer hereunder, (ii) obligated to make
Advances if it is prohibited from doing so by applicable law or (iii) deemed to
have made any representations and warranties of the Servicer hereunder). Any
such assumption shall be subject to Section 7.02 hereof.

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

          (b) [reserved]

          SECTION 3.05 Collection of Mortgage Loans; Collection Accounts;
                       Certificate Account; Pre-Funding Account; Capitalized
                       Interest Account.

          (a) Continuously from the date hereof until the principal and interest
on all Mortgage Loans have been paid in full or such Mortgage Loans have become
Liquidated Mortgage Loans, the Servicer shall proceed in accordance with the
customary and usual standards of practice of prudent mortgage loan servicers to
collect all payments due under each of the related Mortgage Loans when the same
shall become due and payable to the extent consistent with this Agreement and,
consistent with such standard, with respect to Mortgage Loans for which the
Servicer collects escrow payments, shall ascertain and estimate Escrow Payments
and all other charges that will become due and payable with respect to the
Mortgage Loans and the Mortgaged Properties, to the end that the installments
payable by the Mortgagors will be sufficient to pay such charges as and when
they become due and payable. Consistent with the terms of this Agreement, the
Servicer may also waive, modify or vary any term of any Mortgage Loan or consent
to the postponement of strict compliance with any such term or in any manner
grant indulgence to any Mortgagor if in the Servicer's determination such
waiver, modification, postponement or indulgence is not materially adverse to
the interests of the Certificateholders (taking into account any estimated
Realized Loss that might result absent such action); provided, however, that the
Servicer may not modify materially or permit any Subservicer to modify any
Mortgage Loan, including without limitation any modification that would change
the Mortgage Rate, forgive the payment of any principal or interest (unless in
connection with the liquidation of the related Mortgage Loan or except in
connection with prepayments to the extent that such reamortization is not
inconsistent with the terms of the Mortgage Loan), or extend the final maturity
date of such Mortgage Loan, unless such Mortgage Loan is in default or, in the
judgment of the Servicer, such default is reasonably foreseeable; and that no
such modification shall reduce the interest rate on a Mortgage Loan below the
rate at which the Servicing Fee with respect to such Mortgage Loan accrues. In
the event of any such arrangement, the Servicer shall make Advances on the
related Mortgage Loan in accordance with the provisions of Section 4.01 during
the scheduled period in accordance with the amortization schedule of such
Mortgage Loan without modification thereof by reason of such arrangements. The
Servicer shall not be required to institute or join in litigation with respect
to collection of any payment (whether under a Mortgage, Mortgage Note or
otherwise or against any public or governmental authority with respect to a
taking or condemnation) if it reasonably believes that enforcing the provision
of the Mortgage or other instrument pursuant to which such payment is required
is prohibited by applicable law.

          (b) The Servicer shall segregate and hold all funds collected and
received pursuant to a Mortgage Loan separate and apart from any of its own
funds and general assets and shall establish and maintain one or more Collection
Accounts, in the form of time deposit or demand accounts, titled "[Servicer's
name], in trust for the Holders of Credit Suisse First Boston Mortgage
Securities Corp., Home Equity Mortgage Pass-Through Certificates, Series 2003-3"
or, if established and maintained by a Subservicer on behalf of the related
Servicer, "[Subservicer's name], in trust for [Servicer's name]" or
"[Subservicer's name], as agent, trustee and/or bailee of principal and interest
custodial account for [Servicer's name], its successors and assigns, for various
owners of interest in [Servicer's name] mortgage-backed pools". Each Collection
Account shall be an Eligible Account. Any funds deposited in a Collection
Account shall at all times be either invested in Eligible

                                       61
<PAGE>

Investments or shall be fully insured to the full extent permitted under
applicable law. Funds deposited in a Collection Account may be drawn on by the
Servicer in accordance with Section 3.08.

          The Servicer shall deposit in the Collection Account on a daily basis
and retain therein, the following collections remitted by Subservicers or
payments received by the Servicer and payments made by the Servicer subsequent
to the Cut-off Date, other than payments of principal and interest due on or
before the Cut-off Date:

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

          (ii) all payments on account of interest on the Mortgage Loans
     adjusted to the per annum rate equal to the Mortgage Rate reduced by the
     related Servicing Fee Rate;

          (iii) all Liquidation Proceeds on the Mortgage Loans;

          (iv) all Insurance Proceeds on the Mortgage Loans including amounts
     required to be deposited pursuant to Section 3.09 (other than proceeds to
     be held in the Escrow Account and applied to the restoration or repair of
     the Mortgaged Property or released to the Mortgagor in accordance with
     Section 3.09);

          (v) all Advances made by the Servicer pursuant to Section 4.01;

          (vi) with respect to each Principal Prepayment on the Mortgage Loans,
     the Prepayment Interest Shortfall, if any, for the Prepayment Period. The
     aggregate of such deposits shall be made from the Servicer's own funds,
     without reimbursement therefor, up to a maximum amount per month equal to
     the Compensating Interest Payment, if any, for the Mortgage Loans and that
     Distribution Date;

          (vii) any amounts required to be deposited by the Servicer in respect
     of net monthly income from REO Property pursuant to Section 3.11; and

          (viii) any other amounts required to be deposited hereunder including
     all collected Prepayment Penalties.

          The foregoing requirements for deposit into each Collection Account
shall be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, Ancillary Income need not be deposited by the
Servicer into such Collection Account. In addition, notwithstanding the
provisions of this Section 3.05, the Servicer may deduct from amounts received
by it, prior to deposit to the applicable Collection Account, any portion of any
Scheduled Payment representing the applicable Servicing Fee. In the event that
the Servicer shall remit any amount not required to be remitted, it may at any
time withdraw or direct the institution maintaining the related Collection
Account to withdraw such amount from such Collection Account, any provision
herein to the contrary notwithstanding. Such withdrawal or direction may be
accomplished by delivering written notice thereof to the Trustee or such other
institution maintaining such Collection Account which describes the amounts
deposited in error in such Collection Account. The Servicer shall

                                       62
<PAGE>

maintain adequate records with respect to all withdrawals made by it pursuant to
this Section. All funds deposited in a Collection Account shall be held in trust
for the Certificateholders until withdrawn in accordance with Section 3.08.

          (c) On or prior to the Closing Date, the Trustee shall establish and
maintain, on behalf of the Certificateholders, the Certificate Account. The
Trustee shall, promptly upon receipt, deposit in the Certificate Account and
retain therein the following:

          (i) the aggregate amount remitted by the Servicer to the Trustee
     pursuant to Section 3.08(viii);

          (ii) any amount deposited by the Trustee pursuant to Section 3.05(e)
     in connection with any losses on Eligible Investments; and

          (iii) any other amounts deposited hereunder which are required to be
     deposited in the Certificate Account.

          In the event that the Servicer shall remit to the Trustee any amount
not required to be remitted, it may at any time direct the Trustee to withdraw
such amount from the Certificate Account, any provision herein to the contrary
notwithstanding. Such direction may be accomplished by delivering an Officer's
Certificate to the Trustee which describes the amounts deposited in error in the
Certificate Account. All funds deposited in the Certificate Account shall be
held by the Trustee in trust for the Certificateholders until disbursed in
accordance with this Agreement or withdrawn in accordance with Section 3.08. In
no event shall the Trustee incur liability for withdrawals from the Certificate
Account at the direction of the Servicer.

          (d) Each institution at which a Collection Account, the Certificate
Account or the Pre-Funding Account is maintained shall either hold such funds on
deposit uninvested or shall invest the funds therein as directed in writing by
the Servicer (in the case of a Collection Account), the Trustee (in the case of
the Certificate Account) or the Depositor (in the case of the Pre-Funding
Account), in Eligible Investments, which shall mature not later than (i) in the
case of a Collection Account, the second Business Day immediately preceding the
related Distribution Date and (ii) in the case of the Certificate Account and
the Pre-Funding Account, the Business Day immediately preceding the Distribution
Date and, in each case, shall not be sold or disposed of prior to its maturity.
All income and gain net of any losses realized from any such balances or
investment of funds on deposit in a Collection Account shall be for the benefit
of the Servicer as servicing compensation and shall be remitted to it monthly as
provided herein. The amount of any realized losses in a Collection Account
incurred in any such account in respect of any such investments shall promptly
be deposited by the Servicer in the Collection Account. The Trustee in its
fiduciary capacity shall not be liable for the amount of any loss incurred in
respect of any investment or lack of investment of funds held in a Collection
Account or the Pre-Funding Account. All income and gain net of any losses
realized from any such investment of funds on deposit in the Certificate Account
shall be for the benefit of the Trustee as compensation and shall be remitted to
it monthly as provided herein. The amount of any realized losses in the
Certificate Account incurred in any such account in respect of any such
investments shall promptly be deposited by the Trustee in the Certificate
Account. All income and gain net of any losses realized from any such balances
or

                                       63
<PAGE>

investment of funds on deposit in the Pre-Funding Account shall be for the
benefit of the Depositor and shall be remitted to it monthly.

          (e) The Servicer shall give notice to the Trustee, the Seller, each
Rating Agency and the Depositor of any proposed change of the location of the
related Collection Account prior to any change thereof. The Trustee shall give
notice to the Servicer, the Seller, each Rating Agency and the Depositor of any
proposed change of the location of the Certificate Account prior to any change
thereof.

          (f) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Pre-Funding Account. On the Closing Date, the Depositor
shall remit the Pre-Funding Amount to the Trustee for deposit in the Pre-Funding
Account. On each Subsequent Transfer Date, upon satisfaction of the conditions
for such Subsequent Transfer Date set forth in Section 2.01(f), with respect to
the related Subsequent Transfer Agreement, the Trustee shall remit to the
Depositor the applicable Aggregate Subsequent Transfer Amount as payment of the
purchase price for the related Subsequent Mortgage Loans.

          If any funds remain in the Pre-Funding Account on August 24, 2003, to
the extent they represent interest earnings on the amounts originally deposited
into the Pre-Funding Account, the Trustee shall distribute them to the order of
the Depositor. The remaining funds in the Pre- Funding Account shall be
transferred to the Certificate Account to be included as part of principal
distributions to the Class A-1 Certificates and Class A-2 Certificates in the
manner and priority set forth herein on the August 2003 Distribution Date.

          (g) The Trustee shall establish and maintain, on behalf of the
Certificateholders, the Capitalized Interest Account. On the Closing Date, the
Depositor shall remit the Capitalized Interest Deposit to the Trustee for
deposit in the Capitalized Interest Account. On the Business Day prior to each
of the June 2003, July 2003 and August 2003 Distribution Dates, the Trustee
shall transfer from each Capitalized Interest Account to the Certificate Account
an amount equal to the Capitalized Interest Requirement for such Distribution
Date. On each of the June 2003 and July 2003 Distribution Dates, the Overfunded
Interest Amount shall be withdrawn from the Capitalized Interest Account and
paid to the Depositor. Any funds remaining in the Capitalized Interest Account
immediately after the April 2003 Distribution Date shall be paid to the
Depositor.

          SECTION 3.06 Establishment of and Deposits to Escrow Accounts;
                       Permitted Withdrawals from Escrow Accounts; Payments of
                       Taxes, Insurance and Other Charges.

          (a) To the extent required by the related Mortgage Note and not
violative of current law, the Servicer shall segregate and hold all funds
collected and received pursuant to a Mortgage Loan constituting Escrow Payments
separate and apart from any of its own funds and general assets and shall
establish and maintain one or more Escrow Accounts, in the form of time deposit
or demand accounts, titled, "Credit Suisse First Boston Mortgage Securities
Corp., Home Equity Mortgage Pass-Through Certificates, Series 2003-3" or, if
established and maintained by a Subservicer on behalf of the related Servicer,
"[Subservicer's name], in trust for [Servicer's name]" or "[Subservicer's name],
as agent, trustee and/or bailee of taxes and insurance custodial account for

                                       64
<PAGE>

[Servicer's name], its successors and assigns, for various owners of interest in
[Servicer's name] mortgage-backed pools". The Escrow Accounts shall be Eligible
Accounts. Funds deposited in the Escrow Account may be drawn on by the Servicer
in accordance with Section 3.06(b). The creation of any Escrow Account shall be
evidenced by a certification in the form of Exhibit P-1 hereto, in the case of
an account established with the Servicer, or by a letter agreement in the form
of Exhibit P2 hereto, in the case of an account held by a depository other than
the Servicer. A copy of such certification shall be furnished to the Depositor
and Trustee.

          (b) The Servicer shall deposit in its Escrow Account or Accounts on a
daily basis within one Business Day of receipt and retain therein:

          (i) all Escrow Payments collected on account of the related Mortgage
     Loans, for the purpose of effecting timely payment of any such items as
     required under the terms of this Agreement; and

          (ii) all amounts representing Insurance Proceeds which are to be
     applied to the restoration or repair of any Mortgaged Property.

          The Servicer shall make withdrawals from the Escrow Account only to
effect such payments as are required under this Agreement, as set forth in
Section 3.06(c). The Servicer shall be entitled to retain any interest paid on
funds deposited in the related Escrow Account by the depository institution,
other than interest on escrowed funds required by law to be paid to the
Mortgagor. To the extent required by law, the Servicer shall pay interest on
escrowed funds to the Mortgagor notwithstanding that the Escrow Account may be
non-interest bearing or that interest paid thereon is insufficient for such
purposes.

          (c) Withdrawals from the Escrow Account or Accounts may be made by the
Servicer only:

          (i) to effect timely payments of ground rents, taxes, assessments,
     water rates, mortgage insurance premiums, condominium charges, fire and
     hazard insurance premiums or other items constituting Escrow Payments for
     the related Mortgage;

          (ii) to reimburse the Servicer for any Servicing Advances made by the
     Servicer pursuant to this Agreement with respect to a related Mortgage
     Loan, but only from amounts received on the related Mortgage Loan which
     represent late collections of Escrow Payments thereunder;

          (iii) to refund to any Mortgagor any funds found to be in excess of
     the amounts required under the terms of the related Mortgage Loan;

          (iv) for transfer to the related Collection Account to reduce the
    principal balance of the related Mortgage Loan in accordance with the terms
     of the related Mortgage and Mortgage Note;

                                       65
<PAGE>

          (v) for application to restore or repair of the related Mortgaged
     Property in accordance with the procedures outlined in Section 3.09;

          (vi) to pay to the Servicer, or any Mortgagor to the extent required
     by law, any interest paid on the funds deposited in such Escrow Account;
     and

          (vii) to clear and terminate such Escrow Account on the termination of
     this Agreement.

          (d) No later than the Closing Date, the Servicer shall establish and
maintain a sub- account of the Collection Account titled "[Servicer's name],
Simple Interest Excess Sub-Account in trust for the Holders of Credit Suisse
First Boston Mortgage Securities Corp., Home Equity Mortgage Pass-Through
Certificates, Series 2003-3 ". The Servicer shall, on each Determination Date
transfer from the Collection Account to the Simple Interest Excess Sub-Account
all Net Simple Interest Excess, if any, pursuant to Section 3.08(ix), and shall
maintain a record of all such deposits.

          (e) The Servicer shall withdraw amounts on deposit in the Simple
Interest Excess Sub-Account on each Determination Date for deposit to the
Certificate Account in an amount equal to the lesser of (i) the amount on
deposit therein, and (ii) the Net Simple Interest Shortfall for such
Distribution Date.

          (f) The Servicer shall remit to the Trustee which shall thereupon
distribute to the Class X-1 Certificateholder 90% of the balance in the Simple
Interest Excess Sub-Account on the Distribution Date each year occurring in
December, commencing in December 2003. Such distributions shall be deemed to be
made on a first-in, first-out basis. In addition, the Servicer shall clear and
terminate the Simple Interest Excess Sub-Account upon the termination of this
Agreement and retain any funds remaining therein.

          (g) Amounts on deposit in the Simple Interest Excess Sub-Accounts may
be invested in Eligible Investments. All income and gain net of any losses
realized from any such balances or investment of funds on deposit in the Simple
Interest Excess Sub-Account shall be for the benefit of the Servicer as
servicing compensation and shall be remitted to it monthly. The amount of any
net investment losses in the Simple Interest Excess Sub-Account shall promptly
be deposited by the Servicer in such Simple Interest Excess Sub-Account.

          SECTION 3.07 Access to Certain Documentation and Information Regarding
                       the Mortgage Loans; Inspections.

          (a) The Servicer shall afford the Depositor and the Trustee reasonable
access to all records and documentation regarding the Mortgage Loans and all
accounts, insurance information and other matters relating to this Agreement,
such access being afforded without charge, but only upon reasonable request and
during normal business hours at the office designated by the Servicer.

          (b) The Servicer shall inspect the Mortgaged Properties as often as
deemed necessary by the Servicer in the Servicer's sole discretion, to assure
itself that the value of such Mortgaged Property is being preserved. In
addition, if any Mortgage Loan is more than 60 days

                                       66
<PAGE>

delinquent, the Servicer shall conduct subsequent inspections in accordance with
Accepted Servicing Practices or as may be required by the primary mortgage
guaranty insurer. The Servicer shall keep a written or electronic report of each
such inspection.

          SECTION 3.08 Permitted Withdrawals from the Collection Accounts and
                       Certificate Account.

          The Servicer may (and in the case of clause (viii) below, shall) from
time to time make withdrawals from the related Collection Account for the
following purposes:

          (i) to pay to the Servicer (to the extent not previously retained by
     the Servicer) the servicing compensation to which it is entitled pursuant
     to Section 3.14, and to pay to the Servicer, as additional servicing
     compensation, earnings on or investment income with respect to funds in or
     credited to such Collection Account;

          (ii) to reimburse the Servicer for unreimbursed Advances made by it,
     such right of reimbursement pursuant to this subclause (ii) being limited
     to amounts received on the Mortgage Loan(s) in respect of which any such
     Advance was made (including without limitation, late recoveries of
     payments, Liquidation Proceeds, Insurance 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, to the extent
     received by the Servicer);

          (iii) to reimburse the Servicer for any Nonrecoverable Advance
     previously made from collections or proceeds of any of the Mortgage Loans;

          (iv) to reimburse the Servicer for (A) unreimbursed Servicing
     Advances, the Servicer's right to reimbursement pursuant to this clause (A)
     with respect to any Mortgage Loan being limited to amounts received on such
     Mortgage Loan which represent late payments of principal and/or interest
     (including, without limitation, Liquidation Proceeds, Insurance 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
     with respect to such Mortgage Loan) respecting which any such advance was
     made and (B) for unpaid Servicing Fees as provided in Section 3.11;

          (v) to pay to the purchaser, with respect to each Mortgage Loan or
     property acquired in respect thereof that has been purchased pursuant to
     Section 2.02, 2.03 or 3.11, all amounts received thereon after the date of
     such purchase;

          (vi) to reimburse the Servicer or the Depositor for expenses incurred
     by any of them and reimbursable pursuant to Section 6.03 hereof;

          (vii) to withdraw any amount deposited in such Collection Account and
     not required to be deposited therein;

                                       67
<PAGE>

          (viii) on or prior to the Servicer Cash Remittance Date, to withdraw
     an amount equal to the Available Funds plus any related Expense Fees (other
     than the Servicing Fee) for such Distribution Date and any Prepayment
     Penalties received in respect of the Mortgage Loans, subject to the
     collection of funds included in the definition of "Available Funds" and
     remit such amount to the Trustee for deposit in the Certificate Account;
     and

          (ix) to deposit to the Simple Interest Excess Sub-Account any amount
     required to be deposited therein pursuant to Section 3.06(d); and

          (x) to clear and terminate such Collection Account upon termination of
     this Agreement pursuant to Section 9.01 hereof.

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

          The Trustee shall withdraw funds from the Certificate Account for
distributions to the Certificateholders and the Credit Risk Manager, if
applicable, in the manner specified in this Agreement (and to withhold from the
amounts so withdrawn, the amount of any taxes that it is authorized to withhold
pursuant to the last paragraph of Section 8.11). In addition, the Trustee may
from time to time make withdrawals from the Certificate Account for the
following purposes:

          (i) to pay to itself the Trustee Fee and any investment income earned
     for the related Distribution Date;

          (ii) to withdraw and return to the Servicer for deposit to the
     Collection Account any amount deposited in the Certificate Account and not
     required to be deposited therein; and

          (iii) to clear and terminate the Certificate Account upon termination
     of this Agreement pursuant to Section 9.01 hereof.

          SECTION 3.09 Maintenance of Hazard Insurance and Mortgage Impairment
                       Insurance; Claims; Restoration of Mortgaged Property.

          The Servicer shall obtain and maintain a blanket policy insuring
against losses arising from fire and hazards covered under extended coverage on
all of the related Mortgage Loans, which policy shall provide coverage in an
amount equal to the amount at least equal to the lesser of (i) the maximum
insurable value of the improvements securing such Mortgage Loan and (ii) the
greater of (A) the outstanding principal balance of the Mortgage Loan and (B) an
amount such that the proceeds of such policy shall be sufficient to prevent the
Mortgagor and/or the mortgagee from becoming co-insurer. Any amounts collected
by the Servicer under any such policy relating to a

                                       68
<PAGE>

Mortgage Loan shall be deposited in the Collection Account subject to withdrawal
pursuant to Section 3.08. Such policy may contain a deductible clause, in which
case, in the event that there shall not have been maintained on the related
Mortgaged Property a standard hazard insurance policy, and there shall have been
a loss which would have been covered by such policy, the Servicer shall deposit
in the related Collection Account at the time of such loss the amount not
otherwise payable under the blanket policy because of such deductible clause,
such amount to be deposited from the Servicer's funds, without reimbursement
therefor. Upon request of the Trustee, the Servicer shall cause to be delivered
to the Trustee a certified true copy of such policy and a statement from the
insurer thereunder that such policy shall in no event be terminated or
materially modified without 30 days' prior written notice to the Trustee. In
connection with its activities as Servicer of the Mortgage Loans, the Servicer
agrees to present, on behalf of itself, the Depositor, and the Trustee for the
benefit of the Certificateholders, claims under any such blanket policy.

          Pursuant to Section 3.05, any amounts collected by the Servicer under
any such policies (other than amounts to be deposited in the related Escrow
Account and applied to the restoration or repair of the related Mortgaged
Property, or property acquired in liquidation of the Mortgage Loan, or to be
released to the Mortgagor, in accordance with the Servicer's normal servicing
procedures) shall be deposited in the related Collection Account (subject to
withdrawal pursuant to Section 3.08). Any costs incurred by the Servicer in
maintaining such insurance shall be recoverable by the Servicer as a Servicing
Advance out of payments by the related Mortgagor or out of Insurance Proceeds or
Liquidation Proceeds. Notwithstanding anything to the contrary in this
paragraph, the Servicer shall be required to pay the costs of maintaining any
insurance contemplated by this Section 3.09 only to the extent that such
advances, in the good faith judgment of the Servicer, will be recoverable.

          The Servicer need not obtain the approval of the Trustee prior to
releasing any Insurance Proceeds to the Mortgagor to be applied to the
restoration or repair of the Mortgaged Property if such release is in accordance
with Accepted Servicing Practices. At a minimum, the Servicer shall comply with
the following conditions in connection with any such release of Insurance
Proceeds:

          (i) the Servicer shall receive satisfactory independent verification
     of completion of repairs and issuance of any required approvals with
     respect thereto;

          (ii) the Servicer shall take all steps necessary to preserve the
     priority of the lien of the Mortgage, including, but not limited to
     requiring waivers with respect to m and materialmen's liens; and

          (iii) pending repairs or restoration, the Servicer shall place the
     Insurance Proceeds in the related Escrow Account.

          If the Trustee is named as an additional loss payee, the Servicer is
hereby empowered to endorse any loss draft issued in respect of such a claim in
the name of the Trustee.

                                       69

          SECTION 3.10 Enforcement of Due-on-Sale Clauses; Assumption
                       Agreements.

          The Servicer shall use its best efforts to enforce any "due-on-sale"
provision contained in any related Mortgage or Mortgage Note and to deny
assumption by the person to whom the Mortgaged Property has been or is about to
be sold whether by absolute conveyance or by contract of sale, and whether or
not the Mortgagor remains liable on the Mortgage and the Mortgage Note. When the
Mortgaged Property has been conveyed by the Mortgagor, the Servicer shall, to
the extent it has knowledge of such conveyance, exercise its rights to
accelerate the maturity of such Mortgage Loan under the "due-on-sale" clause
applicable thereto, provided, however, that the Servicer shall not exercise such
rights if prohibited by law from doing so or if the exercise of such rights
would impair or threaten to impair any recovery under the related Primary
Insurance Policy, if any.

          If the Servicer reasonably believes it is unable under applicable law
to enforce such "due-on-sale" clause, the Servicer shall enter into (i) an
assumption and modification agreement with the person to whom such property has
been conveyed, pursuant to which such person becomes liable under the Mortgage
Note and the original Mortgagor remains liable thereon or (ii) in the event the
Servicer is unable under applicable law to require that the original Mortgagor
remain liable under the Mortgage Note and the Servicer has the prior consent of
the primary mortgage guaranty insurer, a substitution of liability agreement
with the purchaser of the Mortgaged Property pursuant to which the original
Mortgagor is released from liability and the purchaser of the Mortgaged Property
is substituted as Mortgagor and becomes liable under the Mortgage Note.
Notwithstanding the foregoing, the Servicer shall not be deemed to be in default
under this Section by reason of any transfer or assumption which the Servicer
reasonably believes it is restricted by law from preventing, for any reason
whatsoever. In connection with any such assumption, no material term of the
Mortgage Note, including without limitation, the Mortgage Rate borne by the
related Mortgage Note, the term of the Mortgage Loan or the outstanding
principal amount of the Mortgage Loan shall be changed.

          Subject to the Servicer's duty to enforce any due-on-sale clause to
the extent set forth in this Section 3.10, in any case in which a Mortgaged
Property has been conveyed to a Person by a Mortgagor, and such Person is to
enter into an assumption agreement or modification agreement or supplement to
the Mortgage Note or Mortgage that requires the signature of the Trustee, or if
an instrument of release signed by the Trustee is required releasing the
Mortgagor from liability on the Mortgage Loan, the Servicer shall prepare and
deliver or cause to be prepared and delivered to the Trustee for signature and
shall direct, in writing, the Trustee to execute the assumption agreement with
the Person to whom the Mortgaged Property is to be conveyed and such
modification agreement or supplement to the Mortgage Note or Mortgage or other
instruments as are reasonable or necessary to carry out the terms of the
Mortgage Note or Mortgage or otherwise to comply with any applicable laws
regarding assumptions or the transfer of the Mortgaged Property to such Person.
In connection with any such assumption, no material term of the Mortgage Note
may be changed. Together with each such substitution, assumption or other
agreement or instrument delivered to the Trustee for execution by it, the
Servicer shall deliver an Officer's Certificate signed by a Servicing Officer
stating that the requirements of this Section 3.10 have been met in connection
therewith. The Servicer shall notify the Trustee that any such substitution or
assumption agreement has been

                                       70
<PAGE>

completed by forwarding to the Trustee the original of such substitution or
assumption agreement, which in the case of the original shall be added to the
related Mortgage File and shall, for all purposes, be considered a part of such
Mortgage File to the same extent as all other documents and instruments
constituting a part thereof. Any fee collected by the Servicer for entering into
an assumption or substitution of liability agreement will be retained by the
Servicer as additional servicing compensation.

          SECTION 3.11 Realization Upon Defaulted Mortgage Loans; Repurchase of
                       Certain Mortgage Loans.

          (a) (i) The Servicer shall use reasonable efforts to foreclose upon or
otherwise comparably convert the ownership of properties securing such of the
related Mortgage Loans as come into and continue in default and as to which no
satisfactory arrangements can be made for collection of delinquent payments.
With respect to such of the Mortgage Loans as come into and continue in default,
the Servicer will decide whether to (i) foreclose upon the Mortgaged Properties
securing such Mortgage Loans, (ii) write off the unpaid principal balance of the
Mortgage Loans as bad debt, (iii) take a deed in lieu of foreclosure, (iv)
accept a short sale (a payoff of the Mortgage Loan for an amount less than the
total amount contractually owed in order to facilitate a sale of the Mortgaged
Property by the Mortgagor) or permit a short refinancing (a payoff of the
Mortgage Loan for an amount less than the total amount contractually owed in
order to facilitate refinancing transactions by the Mortgagor not involving a
sale of the Mortgaged Property), (v) arrange for a repayment plan, or (vi) agree
to a modification in accordance with this Agreement. In connection with such
decision, the Servicer shall take such action as (i) the Servicer would take
under similar circumstances with respect to a similar mortgage loan held for its
own account for investment, (ii) shall be consistent with Accepted Servicing
Practices, (iii) the Servicer shall determine consistently with Accepted
Servicing Practices to be in the best interest of the Trustee and
Certificateholders, and (iv) is consistent with the requirements of the insurer
under any Required Insurance Policy; provided, however, that the Servicer shall
not be required to expend its own funds in connection with any foreclosure or
towards the restoration of any property unless it shall determine in its sole
discretion (i) that such restoration and/or foreclosure will increase the
proceeds of liquidation of the related Mortgage Loan after reimbursement to
itself of such expenses and (ii) that such expenses will be recoverable to it
through Liquidation Proceeds (respecting which it shall have priority for
purposes of withdrawals from the Collection Account). The 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 liquidation proceeds with respect to the related Mortgaged
Property, as provided in the definition of Liquidation Proceeds and as provided
in Section 3.08(iv)(A).

          (ii) Notwithstanding anything to the contrary contained in this
Agreement, with respect to any Mortgage Loan that is one hundred twenty (120)
days delinquent, the Servicer shall obtain a broker's price opinion with respect
to the related Mortgaged Property, the cost of obtaining any such broker's price
opinion to be reimbursable to the Servicer as a Servicing Advance pursuant to
Section 3.08(iii) or (iv). After obtaining the related broker's price opinion,
the Servicer will determine whether any Significant Net Recovery is possible
through foreclosure proceedings or other liquidation of the related Mortgaged
Property. If the Servicer determines that (x) no Significant Net Recovery is
possible or (y) the potential Net Recoveries are anticipated to be an amount,
determined by the Servicer in its good faith judgment and in light of other
mitigating

                                       71
<PAGE>

circumstances, that is insufficient to warrant proceeding through foreclosure or
other liquidation of the related Mortgaged Property, it may, at its discretion,
charge off such delinquent Mortgage Loan in accordance with subsections (a)(iii)
and (a)(iv) below.

          (iii) If the Servicer determines based on the broker's price opinion
obtained under paragraph (a)(ii) above and other relevant considerations that
(x) no Significant Net Recovery is possible through foreclosure proceedings or
other liquidation of the related Mortgaged Property or (y) the potential Net
Recoveries are anticipated to be an amount, determined by the Servicer in its
good faith judgment and in light of other mitigating circumstances, that is
insufficient to warrant proceeding through foreclosure or other liquidation of
the related Mortgaged Property, it will be obligated to charge off the related
Mortgage Loan at the time such Mortgage Loan becomes 180 days delinquent. Once a
Mortgage Loan has been charged off, the Servicer will discontinue making
Advances, the Servicer will not be entitled to any additional servicing
compensation (except as described in paragraphs(a)(ii) or (a) (iv) of this
Section 3.11), the Charged Off Loan will give rise to a Realized Loss, and the
Servicer will follow the procedures described in paragraph (a)(iv) below. If the
Servicer determines that (x) a Significant Net Recovery is possible through
foreclosure proceedings or other liquidation of the Mortgaged Property and (y)
the potential Net Recoveries are anticipated to be an amount, determined by the
Servicer in its good faith judgment and in light of other mitigating
circumstances, that is sufficient to warrant proceeding through foreclosure or
other liquidation of the related Mortgaged Property, the Servicer may continue
to make Advances or Servicing Advances on the related Mortgage Loan that has
become 180 days delinquent and will notify the Credit Risk Manager of that
decision.

          (iv) Any Mortgage Loan that becomes a Charged Off Loan may continue to
be serviced by Wilshire for the Certificateholders using Wilshire Special
Servicing. Wilshire will accrue, but not be entitled to any Servicing Fees and
reimbursement of expenses in connection with such Charged Off Loans, except to
the extent of funds available from the aggregate amount of recoveries on all
Charged Off Loans. Such aggregate recovery amounts on Charged Off Loans shall be
paid to Wilshire first, as reimbursement of any outstanding and unpaid expenses,
and second, as any accrued and unpaid Servicing Fees. Wilshire will only be
entitled to previously accrued Servicing Fees and expenses on any such Charged
Off Loans. Wilshire will not be entitled to receive any future unaccrued
Servicing Fees or expenses from collections on such Charged Off Loans. Any
Charged Off Loan serviced by Wilshire using Wilshire Special Servicing shall be
so serviced until the Release Date described below. Any Net Recoveries on such
Charged Off Loans received prior to the Release Date will be treated as
Liquidation Proceeds and included in Available Funds.

          On the date (the "Release Date") which is no more than six months
after the date on which Wilshire begins servicing any Charged Off Loans using
Wilshire Special Servicing, unless specific Net Recoveries are anticipated by
Wilshire on a particular Charged Off Loan (in which case the Release Date will
be delayed until all such specific anticipated Net Recoveries are received),
such Charged Off Loan will be released from the Trust Fund, will no longer be an
asset of any REMIC, and will be transferred to the Class X-2 Certificateholders,
without recourse, and thereafter (i) those Holders will be entitled to any
amounts subsequently received in respect of any such Released Loans, (ii) the
Majority in Interest Class X-2 Certificateholder may designate any servicer to
service any such Released Loan and (iii) the Majority in Interest Class X-2
Certificateholder may

                                       72
<PAGE>

sell any such Released Loan to a third party. Notwithstanding the previous
sentence, if at any time after a Mortgage Loan has been Charged Off and prior to
six months after the date on which Wilshire begins servicing such Charged Off
Loan using Wilshire Special Servicing, Wilshire determines that there will not
be any Net Recoveries on such Charged Off Loan under any circumstances, Wilshire
may release such Charged Off Loan to the Majority in Interest Class X-2
Certificateholder in accordance with the provisions set forth in the previous
sentence.

          Notwithstanding the foregoing, the procedures described above in this
subsection 3.11(a)(iv) relating to the treatment of Charged Off Loans may be
modified at any time at the discretion of the Majority in Interest Class X-1
Certificateholder, with the consent of Wilshire, which consent shall not be
unreasonably withheld,; provided, however, that in no event shall the Majority
in Interest Class X-1 Certificateholder change the fee structure relating to
Charged Off Loans in a manner that would cause fees to be paid to Wilshire other
than from recoveries on Charged Off Loans.

          The Trustee shall track collections received by Wilshire on any
Charged Off Loans based upon loan level data provided to the Trustee by Wilshire
on each Servicer Data Remittance Date in a report in the form of Exhibit U
hereto, identifying the Charged Off Loans as of the related Due Period that
Wilshire will continue to service until the related Release Date using Wilshire
Special Servicing. On each Distribution Date, the Trustee shall verify, based on
the recovery and expense information provided by Wilshire on the related
Servicer Data Remittance Date, (i) the aggregate amount of accrued and unpaid
Servicing Fees to be paid to Wilshire and expenses to be reimbursed to Wilshire
on such Charged Off Loans as of the related Due Period and (ii) the amount of
Net Recoveries on such Charged Off Loans for such Distribution Date. The Trustee
shall be entitled to rely, without independent verification, on the loan level
data provided by Wilshire that identifies the recovery amounts and the
outstanding and unpaid expenses on any Charged Off Loan in order to verify the
amount in clause (ii) of the previous sentence. The Trustee will be responsible
for independently verifying the aggregate amount of accrued and unpaid Servicing
Fees described in clause (i) of the second preceding sentence to be paid to
Wilshire.

          (v) Notwithstanding anything to the contrary contained in this
Agreement, in connection with a foreclosure or acceptance of a deed in lieu of
foreclosure, in the event the Servicer has reasonable cause to believe that a
Mortgaged Property is contaminated by hazardous or toxic substances or wastes,
or if the Trustee otherwise requests, an environmental inspection or review of
such Mortgaged Property conducted by a qualified inspector shall be arranged for
by the Servicer. Upon completion of the inspection, the Servicer shall promptly
provide the Trustee with a written report of environmental inspection.

          (vi) In the event the environmental inspection report indicates that
the Mortgaged Property is contaminated by hazardous or toxic substances or
wastes, the Servicer shall not proceed with foreclosure or acceptance of a deed
in lieu of foreclosure if the estimated costs of the environmental clean up, as
estimated in the environmental inspection report, together with the Servicing
Advances made by the Servicer and the estimated costs of foreclosure or
acceptance of a deed in lieu of foreclosure exceeds the estimated value of the
Mortgaged Property. If however, the aggregate of such clean up and foreclosure
costs and Servicing Advances are less than or equal to the estimated value of
the Mortgaged Property, then the Servicer may, in its reasonable judgment

                                       73
<PAGE>

and in accordance with Accepted Servicing Practices, choose to proceed with
foreclosure or acceptance of a deed in lieu of foreclosure and the Servicer
shall be reimbursed for all reasonable costs associated with such foreclosure or
acceptance of a deed in lieu of foreclosure and any related environmental clean
up costs, as applicable, from the related Liquidation Proceeds, or if the
Liquidation Proceeds are insufficient to fully reimburse the Servicer, the
Servicer shall be entitled to be reimbursed from amounts in the related
Collection Account pursuant to Section 3.08 hereof. In the event the Servicer
does not proceed with foreclosure or acceptance of a deed in lieu of foreclosure
pursuant to the first sentence of this paragraph, the Servicer shall be
reimbursed for all Servicing Advances made with respect to the related Mortgaged
Property from the related Collection Account pursuant to Section 3.08 hereof,
the Servicer shall have no further obligation to service such Mortgage Loan
under the provisions of this Agreement and the related Mortgage Loan will be
transferred to Wilshire in accordance with paragraph (iv) above.

          (b) With respect to any REO Property, the deed or certificate of sale
shall be taken in the name of the Trustee for the benefit of the
Certificateholders, or its nominee, on behalf of the Certificateholders. The
Trustee's name shall be placed on the title to such REO Property solely as the
Trustee hereunder and not in its individual capacity. The Servicer shall ensure
that the title to such REO Property references this Agreement and the Trustee's
capacity hereunder. Pursuant to its efforts to sell such REO Property, the
Servicer shall in accordance with Accepted Servicing Practices manage, conserve,
protect and operate each REO Property for the purpose of its prompt disposition
and sale. The Servicer, either itself or through an agent selected by the
Servicer, shall manage, conserve, protect and operate the REO Property in the
same manner that it manages, conserves, protects and operates other foreclosed
property for its own account, and in the same manner that similar property in
the same locality as the REO Property is managed. The Servicer may rent such
property, as the Servicer deems to be in the best interest of the Trustee 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 Servicer deems to be in
the best interest of the Trustee and the Certificateholders. The Servicer shall
furnish to the Trustee on or before each Distribution Date a statement with
respect to any REO Property covering the operation of such REO Property for the
previous calendar month and the Servicer's efforts in connection with the sale
of such REO Property and any rental of such REO Property incidental to the sale
thereof for the previous calendar month. That statement shall be accompanied by
such other information as the Trustee shall reasonably request and which is
necessary to enable the Trustee to comply with the reporting requirements of the
REMIC Provisions. The net monthly rental income, if any, from such REO Property
shall be deposited in the related Collection Account no later than the close of
business on each Determination Date. The Servicer shall perform the tax
reporting and withholding required by Sections 1445 and 6050J of the Code with
respect to foreclosures and abandonments, the tax reporting required by Section
6050H of the Code with respect to the receipt of mortgage interest from
individuals and any tax reporting required by Section 6050P of the Code with
respect to the cancellation of indebtedness by certain financial entities, by
preparing such tax and information returns as may be required, in the form
required, and delivering the same to the Trustee for filing.

          To the extent consistent with Accepted Servicing Practices, the
Servicer shall also maintain on each REO Property fire and hazard insurance with
extended coverage in amount which is equal to the outstanding principal balance
of the related Mortgage Loan (as reduced by any amount applied as a reduction of
principal at the time of acquisition of the REO Property), liability

                                       74
<PAGE>

insurance and, to the extent required and available under the Flood Disaster
Protection Act of 1973, as amended, flood insurance in the amount required
above. Any costs incurred by the Servicer in maintaining such insurance shall be
recoverable by the Servicer as a Servicing Advance out of payments by the
related Mortgagor or out of Insurance Proceeds or Liquidation Proceeds.
Notwithstanding anything to the contrary in this paragraph, the Servicer shall
be required to pay the costs of maintaining any insurance contemplated by this
Section 3.11(b) only to the extent that such advances, in the good faith
judgment of the Servicer, will be recoverable.

          (c) In the event that the Trust Fund acquires any Mortgaged Property
as aforesaid or otherwise in connection with a default or imminent default on a
Mortgage Loan, the Servicer shall dispose of such Mortgaged Property prior to
three years after the end of the calendar year of its acquisition by the Trust
Fund unless (i) the Trustee shall have been supplied with an Opinion of Counsel
to the effect that the holding by the Trust Fund of such Mortgaged Property
subsequent to such three-year period will not result in the imposition of taxes
on "prohibited transactions" of any REMIC hereunder as defined in section 860F
of the Code or cause any REMIC hereunder to fail to qualify as a REMIC at any
time that any Certificates are outstanding, in which case the Trust Fund may
continue to hold such Mortgaged Property (subject to any conditions contained in
such Opinion of Counsel) or (ii) the Servicer shall have applied for, prior to
the expiration of such three-year period, an extension of such three-year period
in the manner contemplated by Section 856(e)(3) of the Code, in which case the
three-year period shall be extended by the applicable extension period. The
Servicer shall be entitled to be reimbursed from the Collection Account, as a
Servicing Advance, for any costs incurred in obtaining such Opinion of Counsel.
Notwithstanding any other provision of this Agreement, no Mortgaged Property
acquired by the Trust Fund shall be rented (or allowed to continue to be rented)
or otherwise used for the production of income by or on behalf of the Trust Fund
in such a manner or pursuant to any terms that would (i) cause such Mortgaged
Property to fail to qualify as "foreclosure property" within the meaning of
section 860G(a)(8) of the Code or (ii) subject any REMIC hereunder to the
imposition of any federal, state or local income taxes on the income earned from
such Mortgaged Property under Section 860G(c) of the Code or otherwise, unless
the Servicer has agreed to indemnify and hold harmless the Trust Fund with
respect to the imposition of any such taxes.

          In the event of a default on a Mortgage Loan one or more of whose
obligor is not a United States Person, as that term is defined in Section
7701(a)(30) of the Code, in connection with any foreclosure or acquisition of a
deed in lieu of foreclosure (together, "foreclosure") in respect of such
Mortgage Loan, the Servicer will cause compliance with the provisions of
Treasury Regulation Section 1.1445-2(d)(3) (or any successor thereto) necessary
to assure that no withholding tax obligation arises with respect to the proceeds
of such foreclosure except to the extent, if any, that proceeds of such
foreclosure are required to be remitted to the obligors on the Mortgage Loan.

          (d) The decision of the Servicer to foreclose on a defaulted Mortgage
Loan shall be subject to a determination by the 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 REO Properties, net of
reimbursement to the Servicer for expenses incurred (including any property or
other taxes) in connection with such management and net of applicable accrued
and unpaid Servicing Fees, and unreimbursed Advances and Servicing Advances,
shall be applied to the payment of principal of and interest on the related
defaulted Mortgage Loans (with interest accruing

                                       75
<PAGE>

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 and interest on the related Mortgage Notes and shall be deposited into
the related Collection Account. To the extent the net income received during any
calendar month is in excess of the amount attributable to amortizing principal
and accrued interest at the related Mortgage Rate on the related Mortgage Loan
for such calendar month, such excess shall be considered to be a partial
prepayment of principal of the related Mortgage Loan.

          The Servicer shall not acquire any Mortgaged Property on behalf of any
REMIC created hereunder in connection with a default or imminent default on a
Foreclosure Restricted Loan, if acquiring title to the Mortgaged Property
underlying the loan would cause the adjusted basis, for federal income tax
purposes, of these Mortgaged Properties owned by the related REMIC after
foreclosure, along with any other assets owned by the related REMIC other than
"qualified mortgages" and "permitted investments" within the meaning of Section
860G of the Code, to exceed 0.75% of the adjusted basis of the assets of the
related REMIC. If the adjusted basis of such Mortgaged Properties in
foreclosure, along with any other assets owned by the related REMIC, other than
"qualified mortgages" and "permitted investments" with the meaning of Section
860G of the Code, exceed 1.0% of the adjusted basis of the assets of the related
REMIC immediately after the distribution of principal and interest on any
Distribution Date, the Servicer will dispose of enough of such Mortgaged
Properties in foreclosure, for cash or otherwise, so that the adjusted basis of
such Mortgaged Properties in foreclosure, along with any other assets owned by
the related REMIC, other than "qualified mortgages" and "permitted investments"
within the meaning of Section 860G of the Code, will be less than 1.0% of the
adjusted basis of the assets of the related REMIC.

          (e) The proceeds from any liquidation of a Mortgage Loan, as well as
any income from an REO Property, will be applied in the following order of
priority: first, to reimburse the Servicer for any related unreimbursed
Servicing Advances and Servicing Fees; second, to reimburse the Servicer for any
unreimbursed Advances; third, to reimburse the related Collection Account for
any Nonrecoverable Advances (or portions thereof) that were previously withdrawn
by the Servicer pursuant to Section 3.08(iii) that related to such Mortgage
Loan; fourth, to accrued and unpaid interest (to the extent no Advance has been
made for such amount or any such Advance has been reimbursed) on the Mortgage
Loan or related REO Property, at the per annum rate equal to the related
Mortgage Rate reduced by the related Servicing Fee Rate, to the Due Date
occurring in the month in which such amounts are required to be distributed; and
fifth, as a recovery of principal of the Mortgage Loan. Excess proceeds, if any,
from the liquidation of a Liquidated Mortgage Loan will be retained by the
Servicer as additional servicing compensation pursuant to Section 3.14.

          (f) [reserved].

          (g) The Majority in Interest Class X-2 Certificateholder, at its
option, may (but is not obligated to) repurchase from the Trust Fund, (a) any
related Mortgage Loan that is delinquent in payment by three or more Scheduled
Payments or (b) any related Mortgage Loan with respect to which there has been
initiated legal action or other proceedings for the foreclosure of the related
Mortgaged Property either judicially or non-judicially. If it elects to make any
such repurchase, the Majority in Interest Class X-2 Certificateholder shall
repurchase such Mortgage Loan with its own funds at a price equal to the
Repurchase Price for such Mortgage Loan. The Majority in Interest

                                       76
<PAGE>

Class X-2 Certificateholder may designate any servicer to service any such
Mortgage Loan purchased from the Trust.

          SECTION 3.12 Trustee to Cooperate; Release of Mortgage Files.

          Upon the payment in full of any Mortgage Loan, or the receipt by the
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Servicer will immediately notify the Trustee
(or the Custodian, as the case may be) by delivering, or causing to be delivered
a "Request for Release" substantially in the form of Exhibit M. Upon receipt of
such request, the Trustee (or the Custodian, as the case may be) shall within
three Business Days release the related Mortgage File to the Servicer, and the
Trustee shall within three Business Days of the Servicer's direction execute and
deliver to the Servicer the request for reconveyance, deed of reconveyance or
release or satisfaction of mortgage or such instrument releasing the lien of the
Mortgage in each case provided by the Servicer, together with the Mortgage Note
with written evidence of cancellation thereon. The Servicer is authorized to
cause the removal from the registration on the MERS(R) System of such Mortgage,
if applicable, and to execute and deliver, on behalf of the Trustee and the
Certificateholders or any of them, any and all instruments of satisfaction or
cancellation or of partial or full release. Expenses incurred in connection with
any instrument of satisfaction or deed of reconveyance shall be chargeable to
the related Mortgagor to the extent permitted by law and otherwise shall
constitute a Servicing Advance. From time to time and as shall be appropriate
for the servicing or foreclosure of any Mortgage Loan, including 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 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 Mortgage File, the Trustee shall, within three Business Days of
delivery to the Trustee (or the Custodian, as the case may be) of a Request for
Release in the form of Exhibit M signed by a Servicing Officer, release the
Mortgage File to the Servicer. Subject to the further limitations set forth
below, the Servicer shall cause the Mortgage File or documents so released to be
returned to the Trustee (or the Custodian, as the case may be) when the need
therefor by the Servicer no longer exists, unless the Mortgage Loan is
liquidated and the proceeds thereof are deposited in the related Collection
Account, in which case the Servicer shall deliver to the Trustee (or the
Custodian, as the case may be) a Request for Release in the form of Exhibit M,
signed by a Servicing Officer.

          If the Servicer at any time seeks to initiate a foreclosure proceeding
in respect of any Mortgaged Property as authorized by this Agreement, the
Servicer shall deliver or cause to be delivered 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.

                                       77
<PAGE>

          SECTION 3.13 Documents, Records and Funds in Possession of the
                       Servicer to be Held for the Trustee.

          Notwithstanding any other provisions of this Agreement, the Servicer
shall transmit to the Trustee as required by this Agreement all documents and
instruments in respect of a Mortgage Loan coming into the possession of the
Servicer from time to time required to be delivered to the Trustee pursuant to
the terms hereof and shall account fully to the Trustee for any funds received
by the Servicer or which otherwise are collected by the Servicer as Liquidation
Proceeds or Insurance Proceeds in respect of any Mortgage Loan. All Mortgage
Files and funds collected or held by, or under the control of, the Servicer in
respect of any Mortgage Loans, whether from the collection of principal and
interest payments or from Liquidation Proceeds, including but not limited to,
any funds on deposit in a Collection Account, shall be held by the Servicer for
and on behalf of the Trustee and shall be and remain the sole and exclusive
property of the Trustee, subject to the applicable provisions of this Agreement.
The Servicer also agrees that it shall not create, incur or subject any Mortgage
File or any funds that are deposited in the related Collection Account,
Certificate Account or any related 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 Mortgage File or any funds collected on, or
in connection with, a Mortgage Loan, except, however, that the Servicer shall be
entitled to set off against and deduct from any such funds any amounts that are
properly due and payable to the Servicer under this Agreement.

          SECTION 3.14 Servicing Fee.

          As compensation for its services hereunder, the Servicer shall be
entitled to withdraw from the Collection Account or to retain from interest
payments on the related Mortgage Loans the amount of its Servicing Fee for each
Mortgage Loan, less any amounts in respect of its Servicing Fee payable by the
Servicer pursuant to Section 3.05(b)(vi). The Servicing Fee is limited to, and
payable solely from, the interest portion of such Scheduled Payments collected
by the Servicer or as otherwise provided in Section 3.08.

          Additional servicing compensation in the form of Ancillary Income
shall be retained by the Servicer. The Servicer shall be required to pay all
expenses incurred by it in connection with its servicing activities hereunder
(including the payment of any expenses incurred in connection with any
Subservicing Agreement entered into pursuant to Section 3.02) and shall not be
entitled to reimbursement thereof except as specifically provided for in this
Agreement.

          SECTION 3.15 Access to Certain Documentation.

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

                                       78
<PAGE>

regarding the Mortgagors and the failure of the Servicer to provide access as
provided in this Section as a result of such obligation shall not constitute a
breach of this Section. Nothing in this Section 3.15 shall require the Servicer
to collect, create, collate or otherwise generate any information that it does

Trustee an Officer's Certificate stating, as to the signer thereof, that (i) a
review of the activities of the Servicer during the preceding calendar year and
of the performance of the Servicer under this Agreement has been made under such

on such review, the Servicer has fulfilled all its obligations under this

          SECTION 3.17 Annual Independent Public Accountants' Servicing
                       Statement; Financial Statements.

          Not later than the earlier of (a) March 15 of each calendar year
(other than the calendar year during which the Closing Date occurs) or (b) with
respect to any calendar year during which the Depositor's annual report on Form
10-K is required to be filed in accordance with the Exchange Act and the rules
and regulations of the Commission, 15 calendar days before the date on which the
Depositor's annual report on Form 10-K is required to be filed in accordance
with the Exchange Act and the rules and regulations of the Commission (or, in
each case, if such day is not a Business Day, the immediately preceding Business
Day), the Servicer at its expense shall cause a nationally or regionally
recognized firm of independent public accountants (who may also render other
services to the Servicer, the Seller or any affiliate thereof) which is a member
of the American Institute of Certified Public Accountants to furnish a statement
to the Trustee and the Depositor to the effect that such firm has examined
certain documents and records relating to the servicing of mortgage loans which
the Servicer is servicing, which may include the related Mortgage Loans or
similar mortgage loans, and that, on the basis of such examination, conducted
substantially in compliance with the Uniform Single Attestation Program for
Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved
Mortgagees and Loan Correspondent Programs, nothing has come to their attention
which would indicate that such servicing has not been conducted in compliance
with Accepted Servicing Practices, except for (a) such exceptions as such firm
shall believe to be immaterial, and (b) such other exceptions as shall be set
forth in such statement. In addition, the Servicer shall disclose to such firm
all significant deficiencies relating to the Servicer's compliance with the
minimum servicing standards set forth in this Agreement. In rendering such
statement, such firm may rely, as to matters relating to direct servicing of
mortgage loans by

                                       79
<PAGE>

Subservicers, upon comparable statements for examinations conducted
substantially in compliance with the Uniform Single Attestation Program for
Mortgage Bankers or the Audit Guide for HUD Approved Title II Approved
Mortgagees and Loan Correspondent Programs (rendered within one year of such
statement) of independent public accountants with respect to the related
Subservicer. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request at the Servicer's expense, provided such
statement is delivered by the Servicer to the Trustee.

          SECTION 3.18 Maintenance of Fidelity Bond and Errors and Omissions
                       Insurance.

          The Servicer shall maintain with responsible companies, at its own
expense, a blanket Fidelity Bond and an Errors and Omissions Insurance Policy,
with broad coverage on all officers, employees or other persons acting in any
capacity requiring such persons to handle funds, money, documents or papers
relating to the related Mortgage Loans ("Servicer Employees"). The amount of
coverage under any such Fidelity Bond and Errors and Omissions Insurance Policy
shall be at least equal to the coverage maintained by the Servicer in order to
be acceptable to Fannie Mae or Freddie Mac to service loans for it or otherwise
in an amount as is commercially available at a cost that is generally not
regarded as excessive by industry standards. No provision of this Section 3.18
requiring such Fidelity Bond and Errors and Omissions Insurance Policy shall
diminish or relieve the Servicer from its duties and obligations as set forth in
this Agreement. The minimum coverage under any such bond and insurance policy
shall be at least equal to the corresponding amounts required by Fannie Mae.
Upon the request of the Trustee, the Servicer shall cause to be delivered to the
Trustee a certificate of insurance of the insurer and the surety including a
statement from the surety and the insurer that such fidelity bond and insurance
policy shall in no event be terminated or materially modified without 30 days'
prior written notice to the Trustee.

          SECTION 3.19 Duties of the Credit Risk Manager.

          The Depositor appoints The Murrayhill Company as Credit Risk Manager.
For and on behalf of the Depositor, and the Trustee, the Credit Risk Manager
will provide reports and recommendations concerning Mortgage Loans that are past
due, as to which there has been commencement of foreclosure, as to which there
has been forbearance in exercise of remedies which are in default, as to which
obligor is the subject of bankruptcy, receivership, or an arrangement of
creditors, or as to which have become REO Properties. Such reports and
recommendations will be based upon information provided to the Credit Risk
Manager pursuant to the Credit Risk Management Agreement and the Credit Risk
Manager shall look solely to the Servicer for all information and data
(including loss and delinquency information and data) and loan level information
and data relating to the servicing of the Mortgage Loans. If the Credit Risk
Manager is no longer able to perform its duties hereunder, the Depositor shall
terminate the Credit Risk Manager and cause the appointment of a successor
Credit Risk Manager. Upon any termination of the Credit Risk Manager or the
appointment of a successor Credit Risk Manager, the Depositor shall give written
notice thereof to the Seller, the Servicer, the Trustee and each Rating Agency.
Notwithstanding the foregoing, the termination of the Credit Risk Manager
pursuant to this Section 3.19 shall not become effective until the appointment
of a successor Credit Risk Manager.

          SECTION 3.20 Limitation Upon Liability of the Credit Risk Manager.

          Neither the Credit Risk Manager, nor any of the directors, officers,
employees or agents of the Credit Risk Manager, shall be under any liability to
the Trustee, the Certificateholders or the Depositor for any action taken or for
refraining from the taking of any action in good faith pursuant to this
Agreement, in reliance upon information provided by the Servicer under the
Credit Risk Management Agreements or of errors in judgment; provided, however,
that this provision shall not protect the Credit Risk Manager or any such person
against liability that would otherwise be imposed by reason of willful
malfeasance, bad faith or gross negligence in its performance of its duties
under this Agreement or the Credit Risk Manager Agreement. The Credit Risk
Manager and any director, officer, employee or agent of the Credit Risk Manager
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, and may
rely in good faith upon the accuracy of information furnished by any Servicer
pursuant to the Credit Risk Management Agreement in the performance of its
duties thereunder and hereunder.

          SECTION 3.21 Advance Facility.

          (a) Wilshire is hereby authorized to enter into a financing or other
facility (any such arrangement, an "Advance Facility") under which (1) Wilshire
assigns or pledges to another Person (an "Advancing Person") its rights under
this Agreement to be reimbursed for any Advances or Servicing Advances and/or
(2) an Advancing Person agrees to fund some or all Advances and/or Servicing
Advances required to be made by Wilshire pursuant to this Agreement. No consent
of the Trustee, Certificateholders or any other party is required before
Wilshire may enter into an Advance Facility; PROVIDED, HOWEVER, that the consent
of the Trustee (which consent shall not be unreasonably withheld) shall be
required before Wilshire may cause to be outstanding at one time more than one
Advance Facility with respect to Advances or more than one Advance Facility with
respect to Servicing Advances. Notwithstanding the existence of any Advance
Facility under which an Advancing Person agrees to fund Advances and/or
Servicing Advances on the Servicer's behalf, Wilshire shall remain obligated
pursuant to this Agreement to make Advances and Servicing Advances pursuant to
and as required by this Agreement, and shall not be relieved of such obligations
by virtue of such Advance Facility. If Wilshire enters into an Advance Facility,
and for so long as an Advancing Person remains entitled to receive reimbursement
for any Advances or Servicing Advances outstanding and previously unreimbursed
pursuant to this Agreement, then Wilshire may elect by providing written notice
to the Trustee not to be permitted to reimburse itself for Advances and/or
Servicing Advances, as applicable, pursuant to Section 3.08 of this Agreement,
but following any such election Wilshire shall be required to include amounts
collected that would otherwise be retained by Wilshire to reimburse it for
previously unreimbursed Advances ("Advan Reimbursement Amounts") and/or
previously unreimbursed Servicing Advances ("Servicing Advance Reimbursement
Amounts" and together with Advance Reimbursement Amounts, "Reimbursement
Amounts") (in each case to the extent such type of Reimbursement Amount is
included in the Advance Facility) in the remittance to the Trustee made pursuant
to this Agreement to the extent of amounts on deposit in the Collection Account
on the related Servicer Cash Remittance Date. Notwithstanding anything to the
contrary herein, in no event shall Advance Reimbursement Amounts or Servicing
Advance Reimbursement Amounts be included in Interest Remittance Amounts or
Principal Remittance Amounts or distributed to Certificateholders.

                                       81
<PAGE>

Wilshire, if making the election set forth herein, shall report to the Trustee
the portions of the Reimbursement Amounts that consist of Advance Reimbursement
Amounts and Servicing Advance Reimbursement Amounts, respectively.

          (b) If Wilshire enters into an Advance Facility and makes the election
set forth in Section 3.21(a), Wilshire and the related Advancing Person shall
deliver to the Trustee a written notice and payment instruction (an "Advance
Facility Notice"), providing the Trustee with written payment instructions as to
where to remit Advance Reimbursement Amounts and/or Servicing Advance
Reimbursement Amounts (each to the extent such type of Reimbursement Amount is
included within the Advance Facility) on subsequent Distribution Dates. The
payment instruction shall require the applicable Reimbursement Amounts to be
distributed to the Advancing Person or to a trustee or custodian (an "Advance
Facility Trustee") designated in the Advance Facility Notice. An Advance
Facility Notice may only be terminated by the joint written direction of
Wilshire and the related Advancing Person (and any related Advance Facility
Trustee); PROVIDED, HOWEVER, that the provisions of this Section 3.21 shall
cease to be applicable when all Advances and Servicing Advances funded by an
Advancing Person, and when all Advances and Servicing Advances (the rights to be
reimbursed for which have been assigned or pledged to an Advancing Person), have
been repaid to the related Advancing Person in full.

          (c) Reimbursement Amounts shall consist solely of amounts in respect
of Advances and/or Servicing Advances made with respect to the Mortgage Loans
for which Wilshire would be permitted to reimburse itself in accordance with
Section 3.08(ii), (iii) and (iv) hereof, assuming Wilshire had made the related
Advance(s) and/or Servicing Advance(s). Notwithstanding the foregoing, no Person
shall be entitled to reimbursement from funds held in the Collection Account for
future distribution to Certificateholders pursuant to the provisions of Section
4.01. The Trustee shall not have any duty or liability with respect to the
calculation of any Reimbursement Amount and shall be entitled to rely without
independent investigation on the Advance Facility Notice and on the Servicer's
report of the amount of Advance Reimbursement Amounts and Servicing Advance
Reimbursement Amounts that were included in the remittance from Wilshire to the
Trustee pursuant to Section 3.08(viii). Wilshire shall maintain and provide to
any successor Servicer a detailed accounting on a loan-by-loan basis as to
amounts advanced by, pledged or assigned to, and reimbursed to any Advancing
Person. The successor Servicer shall be entitled to rely on any such information
provided by Wilshire and the successor Servicer shall not be liable for any
errors in such information.

          (d) An Advancing Person who receives an assignment or pledge of the
rights to be reimbursed for Advances and/or Servicing Advances, and/or whose
obligations hereunder are limited to the funding of Advances and/or Servicing
Advances shall not be required to meet the criteria for qualification of a
Subservicer set forth in Section 3.02 hereof.

          (e) With respect to any Advance Facility pursuant to which Wilshire
has made the election set forth in Section 3.21(a), the documentation
establishing any Advance Facility shall require that Reimbursement Amounts
distributed with respect to each Mortgage Loan be allocated to outstanding
unreimbursed Advances or Servicing Advances (as the case may be) made with
respect to that Mortgage Loan on a "first-in, first-out" (FIFO) basis. Such
documentation shall also require Wilshire to provide to the related Advancing
Person or Advance Facility Trustee loan-by-

                                       82
<PAGE>

loan information with respect to each Reimbursement Amount distributed by the
Trustee to such Advancing Person or Advance Facility Trustee on each
Distribution Date, to enable the Advancing Person or Advance Facility Trustee to
make the FIFO allocation of each Reimbursement Amount with respect to each
Mortgage Loan. Wilshire shall remain entitled to be reimbursed by the Advancing
Person or Advance Facility Trustee for all Advances and Servicing Advances
funded by Wilshire to the extent the related rights to be reimbursed therefor
have not been assigned or pledged to an Advancing Person.

          (f) If Wilshire enters into an Advance Facility, Wilshire shall
indemnify the Trustee and the Trust and any successor Servicer, as applicable,
from and against any claims, losses, liabilities or damages resulting from any
claim by the related Advancing Person, except to the extent that such claim,
loss, liability or damage resulted from or arose out of negligence, recklessness
or willful misconduct on the part of the successor Servicer or the Trustee, or
failure by the successor Servicer or the Trustee to remit funds as required by
Section 3.21(b). Any amendment to this Section 3.21 or to any other provision of
this Agreement that may be necessary or appropriate to effect the terms of an
Advance Facility as described generally in this Section 3.21, including
amendments to add provisions relating to a successor Servicer, may be entered
into by the Trustee, the Seller and Wilshire without the consent of any
Certificateholder notwithstanding anything to the contrary in Section 10.01 of
or elsewhere in this Agreement.

                                DISTRIBUTIONS AND
                            ADVANCES BY THE SERVICER

          SECTION 4.01 Advances by the Servicer.

          The Servicer shall deposit in a Collection Account an amount equal to
(i) with respect to the Mortgage Loans other than the Simple Interest Mortgage
Loans, all Scheduled Payments (with interest at the Mortgage Rate less the
Servicing Fee Rate) which were due but not received on the related Mortgage
Loans during the applicable Due Period and (ii) with respect to the Simple
Interest Mortgage Loans, 30 day's interest on each such Mortgage Loan for which
the Scheduled Payment was due but not received during the applicable Due Period,
less the Servicing Fee; provided however, that with respect to any Balloon Loan
that is delinquent on its maturity date, the Servicer will not be required to
advance the related balloon payment but will be required to continue to make
Advances in accordance with this Section 4.01 with respect to such Balloon Loan
in an amount equal to an assumed scheduled payment that would otherwise be due
based on the original amortization schedule for that Mortgage Loan (with
interest at the Mortgage Rate less the Servicing Fee Rate). The Servicer's
obligation to make such Advances as to any related Mortgage Loan will continue
through the last Scheduled Payment due prior to the payment in full of such
Mortgage Loan, or through the date that the related Mortgaged Property has, in
the judgment of the Servicer, been completely liquidated; provided however, that
such obligation with respect to any related Mortgage Loan shall cease if the
Servicer determines, in its reasonable opinion, that Advances with respect to
such Mortgage Loan are Nonrecoverable Advances; provided that the Servicer will
be required to make Advances until the earlier of (i) the time at which the
related Mortgage Loan becomes 120 days delinquent or (ii) the time at which the
Servicer determines that such Advances with respect to such Mortgage Loan are
Nonrecoverable Advances. In the event that the Servicer determines that any such
Advances are Nonrecoverable Advances, the Servicer shall provide the Trustee
with a certificate signed by a Servicing Officer evidencing such determination.

          If an Advance is required to be made hereunder, the Servicer shall on
the second Business Day immediately preceding the Distribution Date immediately
following the related Determination Date either (i) deposit in the Collection
Account from its own funds an amount equal to such Advance, (ii) cause to be
made an appropriate entry in the records of the Collection Account that funds in
such account being held for future distribution or withdrawal have been, as
permitted by this Section 4.01, used by the Servicer to make such Advance or
(iii) make Advances in the form of any combination of clauses (i) and (ii)
aggregating the amount of such Advance. Any such funds being held in a
Collection Account for future distribution and so used shall be replaced by the
Servicer from its own funds by deposit in such Collection Account on or before
any future Distribution Date in which such funds would be due. The Servicer
shall be entitled to be reimbursed from the Collection Account for all Advances
of its own funds made pursuant to this Section as provided in Section 3.08.

each case, to the extent of such Available Funds remaining:

          (i) On each Distribution Date, the Trustee shall distribute the

          C. to the Class M-1 Certificates, the Class M-1 Principal Payment

          SECTION 4.03 [Reserved]

          SECTION 4.04 [Reserved]

          SECTION 4.05 Allocation of Realized Losses.

          On each Distribution Date, the Trustee shall determine the total of
the Applied Loss Amount, if any, for such Distribution Date. The Applied Loss
Amount for any Distribution Date shall be applied by reducing the Class
Principal Balance of each Class of Subordinate Certificates beginning with the
Class of Subordinate Certificates then outstanding with the lowest relative
payment priority, in each case until the respective Class Principal Balance
thereof is reduced to zero. Any Applied Loss Amount allocated to a Class of
Subordinate Certificates shall be allocated among the Subordinate Certificates
of such Class in proportion to their respective Percentage Interests.

          All Realized Losses on the Mortgage Loans shall be allocated on each
Distribution Date to the following REMIC 1 Regular Interests: first, to REMIC 1
Regular Interests LTI-1 until the Uncertificated Principal Balance thereof has
been reduced to zero, then to REMIC 1 Regular Interest LTI-1PF until the
Uncertificated Principal Balance thereof has been reduced to zero, however, that
with respect to the first three Distribution Dates, Realized Losses relating to
the Initial Mortgage Loans shall be allocated to REMIC 1 Regular Interest LTI-1
and Realized Losses relating to the Subsequent Mortgage Loans shall be allocated
to REMIC 1 Regular Interest LTI-1PF until the Uncertificated Principal Balance
thereof has been reduced to zero. All Realized Losses on the REMIC 1 Regular
Interests LTI-1 and LTI-1PF shall be deemed to have been allocated to the
following REMIC 2 Regular Interests in the specified percentages, as follows:
first to Uncertificated Accrued Interest payable to the REMIC 2 Regular
Interests MT-AA and MT-ZZ up to an aggregate amount equal to the excess of (a)
the REMIC 2 Interest Loss Allocation Amount over (b) Prepayment Interest
Shortfalls (to the extent not covered by Compensating Interest) relating to the
Mortgage Loans for such Distribution Date, 98% and 2%, respectively; second, to
the Uncertificated Principal Balances of the REMIC 2 Regular Interests MT-AA and
MT-ZZ up to an aggregate

                                       88

amount equal to the REMIC 2 Principal Loss Allocation Amount, 98% and 2%,
respectively; third, to the Uncertificated Principal Balances of REMIC 2 Regular
Interest MT-AA, REMIC 2 Regular Interest MT-B and REMIC 2 Regular Interest
MT-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal Balance
of REMIC 2 Regular Interest MT-B has been reduced to zero; fourth, to the
Uncertificated Principal Balances of REMIC 2 Regular Interest MT-AA, REMIC 2
Regular Interest MT-M2 and REMIC 2 Regular Interest MT-ZZ, 98%, 1% and 1%,
respectively, until the Uncertificated Principal Balance of REMIC 2 Regular
Interest MT-M2 has been reduced to zero; and fifth, to the Uncertificated
Principal Balances of REMIC 2 Regular Interest MT-AA, REMIC 2 Regular Interest
MT-M1 and REMIC 2 Regular Interest MT-ZZ, 98%, 1% and 1%, respectively, until
the Uncertificated Principal Balance of REMIC 2 Regular Interest MT-M1 has been
reduced to zero.

               (c) to the Holders of REMIC 1 Regular Interest LTI-1, until the
     Uncertificated Principal Balance of Uncertificated REMIC 1 Regular Interest
     LTI-1 is reduced to zero;

               (d) to the Holders of REMIC 1 Regular Interest LTI-1PF, until the
     Uncertificated Principal Balance of REMIC 1 Regular Interest LTI-1PF is
     reduced to zero; and

          (iii) any remaining amount to the Holders of the Class R-1 Interest;

provided, however, that for the first three Distribution Dates, such amounts

          (b) Distributions on the REMIC 2 Regular Interests.

          On each Distribution Date, the Trustee shall cause in the following
order of priority, the following amounts to be distributed by REMIC 2 to REMIC 3

     Accrued Interest for such Distribution Date, plus (B) any amounts in
     respect thereof remaining unpaid from previous Distribution Dates. Amounts
     payable as Uncertificated Accrued Interest in respect of REMIC 2 Regular
     Interest MT-ZZ shall be reduced when the REMIC 2 Overcollateralization
     Amount is less than the REMIC 2 Overcollateralization Target Amount, by the
     lesser of (x) the amount of such difference and (y) the REMIC 2 Regular
     Interest MT-ZZ Maximum Interest Deferral Amount;

          (ii) second, to the Holders of REMIC 2 Regular Interests, in an amount

          (iii) third, to the Holders of REMIC 2 Regular Interests, in an amount
     equal to the remainder of the Available Funds for such Distribution Date
     after the distributions made pursuant to clauses (i) and (ii) above,
     allocated as follows:

               (a) with respect to the Holders of REMIC 2 Regular Interest
     MT-AA, 98.00% of such remainder, until the Uncertificated Principal Balance
     of such Uncertificated REMIC 2 Regular Interest is reduced to zero;

               (b) with respect to the Holders of REMIC 2 Regular Interest
     MT-A1, MT-A2, MT-M1, MT-M2 and MT-B, 1.00% of such remainder, in the same

               (d) any remaining amount to the Holders of the Class A-R
     Certificates (in respect of the Class R-2 Interest);

provided, however, 98.00% and 2.00% of any principal payments that are
attributable to an Overcollateralization Release Amount shall be allocated to
Holders of REMIC 2 Regular Interest MT-AA and REMIC 2 Regular Interest MT-ZZ,
respectively.

          SECTION 4.08 [Reserved].

          SECTION 4.09 Prepayment Penalties.

          Notwithstanding anything in this Agreement to the contrary, in the
event of a Principal Prepayment of a Mortgage Loan, the Servicer may not waive
any Prepayment Penalty or portion thereof required by the terms of the related
Mortgage Note unless (i) the Mortgage Loan is in default or foreseeable default
and such waiver (a) is standard and customary in servicing similar mortgage
loans to the Mortgage Loans and (b) would, in the reasonable judgment of the
Servicer, maximize recovery of total proceeds taking into account the value of
such Prepayment Penalty and the related Mortgage Loan or (ii)(A) the
enforceability thereof is limited (1) by bankruptcy, insolvency, moratorium,
receivership, or other similar law relating to creditors' rights generally or
(2) due to acceleration in connection with a foreclosure or other involuntary
payment, or (B) the enforceability is otherwise limited or prohibited by
applicable law. For the avoidance of doubt, the Servicer may waive a Prepayment
Penalty in connection with a short sale or short payoff on a defaulted Mortgage
Loan. If the Servicer has waived all or a portion of a Prepayment Penalty
relating to a Principal Prepayment, other than as provided above, the Servicer
shall deliver to the Trustee no later than the Business Day immediately
preceding the next Distribution Date, for deposit into the Certificate Account
the amount of such Prepayment Penalty (or such portion thereof as had been
waived) for distribution in accordance with the terms of this Agreement;
provided, however, the Servicer shall not have any obligation to pay the amount
of any uncollected Prepayment Penalty under this Section 4.09 if the Servicer
did not have a copy of the related Mortgage Note, the Servicer requested via
email a copy of the same from the Trustee and the Trustee failed to provide such
a copy within two (2) Business Days of receipt of such request. If the Servicer
has waived all or a portion of a Prepayment Penalty for any reason, it shall
promptly notify the Trustee thereof and shall include such information in any
monthly reports it provides the Trustee.

          SECTION 4.10 Servicer to Cooperate.

          The Servicer shall provide to the Trustee the information set forth in
Exhibit Z hereto in such form as the Trustee shall reasonably request with
respect to each Mortgage Loan no later than twelve noon on the Servicer Data
Remittance Date to enable the Trustee to calculate the amounts to be distributed
to each Class of Certificates and otherwise perform its distribution, accounting
and reporting requirements hereunder.

          SECTION 4.11 The Interest Rate Cap Agreement.

          (a) On the Closing Date, the Trustee shall establish and maintain in
its name, in trust for the benefit of the Certificates, the Interest Rate Cap
Account. The Interest Rate Cap Account shall be an Eligible Account, and funds
on deposit therein shall be held separate and apart from, and shall not be
commingled with, any other moneys, including without limitation, other moneys
held by the Trustee pursuant to this Agreement.

          (b) On or prior to the Closing Date, the Trustee, on behalf of the
Trust, is hereby directed to enter into the Interest Rate Cap Agreement for the
benefit of the Holders of the LIBOR

                                       92
<PAGE>

Certificates. The Interest Rate Cap Agreement will be an asset of the Trust Fund
but will not be an asset of any REMIC. The Trustee shall deposit any amounts
received with respect to the Interest Rate Cap Agreement into the Interest Rate
Cap Account.

          (c) The Trustee will prepare and deliver any notices required to be
delivered to the Interest Rate Cap Agreement Counterparty under Sections 2(b),
2(d), 4(d), 5(a), 6(a), 6(b), 6(d) and 12(b) of the ISDA Master Agreement and
Parts 3(a) and 5(g) of Schedule B to the Confirmation.

          (d) The Trustee shall terminate the Interest Rate Cap Agreement
Counterparty upon the occurrence of an event of default under the Interest Rate
Cap Agreement of which a Responsible Officer of the Trustee has actual
knowledge. Upon such a termination, the Interest Rate Cap Agreement Counterparty
may be required to pay a termination payment to the Trustee in respect of the
Interest Rate Cap Agreement. Any such termination payment shall be applied by
the Trustee to the purchase of a substantially equivalent interest rate cap
agreement at the direction of the Majority in Interest Class X-1
Certificateholder.

          (e) On each Distribution Date, the Trustee shall distribute amounts on
deposit in the Interest Rate Cap Account to pay the following amounts:

          (i) to the Class M-1, Class M-2 and Class B Certificates, in that
     order, any applicable Deferred Amounts, with interest therein at the
     applicable Pass-Through Rate, prior to giving effect to amounts available
     to be paid in respect of Deferred Amounts as described in Section
     4.02(b)(iv)C. through E. on such Distribution Date; and

          (ii) to the Principal Remittance Amount, up to the amount of Realized
     Losses on the Mortgage Loans incurred during the related Collection Period,
     prior to giving effect to any Excess Cashflow Loss Payment.

          (f) Funds in the Interest Rate Cap Account may be invested in Eligible
Investments by the Trustee at the direction of the Majority in Interest Class
X-1 Certificateholder maturing on or prior to the next succeeding Distribution
Date. The Trustee shall account for the Interest Rate Cap Account as an outside
reserve fund within the meaning of Treasury regulation 1.860G-2(h) and not an
asset of any REMIC created pursuant to this Agreement. The Trustee shall treat
amounts paid by the Interest Rate Cap Account as payments made from outside the
R for all federal tax purposes. Any net investment earnings on such amounts
shall be payable to the Class X-1 Certificateholders. The Class X-1
Certificateholders will be the owner of the Interest Rate Cap Account for
federal tax purposes and the Majority in Interest Class X-1 Certificateholder
shall direct the Trustee in writing as to the investment of amounts therein. In
the absence of such written direction, all funds in the Interest Rate Cap
Account shall remain uninvested with no liability for interest or other
compensation thereon. The Trustee shall have no liability for losses on
investments in Eligible Investments made pursuant to this Section 4.10(f) (other
than as obligor on any such investments). Upon termination of the Trust Fund,
any amounts remaining in the Interest Rate Cap Account shall be distributed to
the Class X-1 Certificateholders.

                                       93
<PAGE>

          (g) Amounts paid under the Interest Rate Cap Agreement not used on any
Distribution Date as described in Section 4.11(e) shall remain on deposit in the
Interest Rate Cap Account and may be available on future Distribution Dates to
make the payments described in Section 4.11(e). However, at no time shall the
amount on deposit in the Interest Rate Cap Account exceed the Target Amount. The
"Target Amount" will be calculated on each Distribution Date, after giving
effect to withdrawals from the Interest Rate Cap Account on such Distribution
Date and distribution and allocation of losses on the LIBOR Certificates on such
Distribution Date, and will equal the sum of (A) the excess, if any, of the
Targeted Overcollateralization Amount over the Overcollateralization Amount, in
each case for such Distribution Date and (B) an amount equal to the excess, if
any, of (1) $756,000 over (2) the aggregate of all amounts paid from the
Interest Rate Cap Account on such Distribution Date and all previous
Distribution Dates pursuant to clauses (e)(i) and (ii) of this Section 4.11. On
each Distribution Date, the Trustee shall distribute amounts in the Interest
Rate Cap Account in excess of the Target Amount (after giving effect to all
distributions on such Distribution Date) and any amounts remaining therein at
the termination of the Trust Fund, to the Class X-1 Certificateholders.

                                   ARTICLE V

                                THE CERTIFICATES

          SECTION 5.01 The Certificates.

          The Certificates shall be substantially in the forms attached hereto
as exhibits. The Certificates shall be issuable in registered form, in the
minimum denominations, integral multiples in excess thereof (except that one
Certificate in each Class may be issued in a different amount which must be in
excess of the applicable minimum denomination) and aggregate denominations per
Class set forth in the Preliminary Statement.

          Subject to Section 9.02 respecting the final distribution on the
Certificates, on each Distribution Date the Trustee shall make distributions to
each Certificateholder of record on the preceding Record Date either (x) by wire
transfer in immediately available funds to the account of such holder at a bank
or other entity having appropriate facilities therefor, if (i) such Holder has
so notified the Trustee at least five Business Days prior to the related Record
Date and (ii) such Holder shall hold (A) a Notional Amount Certificate, (B) 100%
of the Class Principal Balance of any Class of Certificates or (C) Certificates
of any Class with aggregate principal Denominations of not less than $1,000,000
or (y) by check mailed by first class mail to such Certificateholder at the
address of such holder appearing in the Certificate Register.

          The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer upon the written order of the
Depositor. Certificates bearing the manual or facsimile signatures of
individuals who were, at the time such signatures were affixed,

                                       94
<PAGE>

authorized to sign on behalf of the Trustee shall bind the Trustee,
notwithstanding that such individuals or any of them have ceased to be so
authorized prior to the countersignature and delivery of any 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 countersigned by the Trustee by manual signature, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates shall be dated the date of their countersignature. On the
Closing Date, the Trustee shall countersign the Certificates to be issued at the
written direction of the Depositor, or any affiliate thereof.

          The Depositor shall provide, or cause to be provided, to the Trustee
on a continuous basis, an adequate inventory of Certificates to facilitate
transfers.

          The Trustee shall have no obligation or duty to monitor, determine or
inquire as to compliance with any restriction or transfer imposed under Article
V of this Agreement or under applicable law with respect to any transfer of any
Certificate, or any interest therein, other than to require delivery of the
certification(s) and/or opinions of counsel described in Article V applicable
with respect to changes in registration of record ownership of Certificates in
the Certificate Register. The Trustee shall have no liability for transfers,
including transfers made through the book-entry facilities of the Depository or
between or among Depository Participants or beneficial owners of the
Certificates made in violation of applicable restrictions.

          SECTION 5.02 Certificate Register; Registration of Transfer and
                       Exchange of Certificates.

          (a) The Trustee shall maintain, or cause to be maintained in
accordance with the provisions of Section 5.06, a Certificate Register for the
Trust Fund in which, subject to the provisions of subsections (b) and (c) below
and 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 and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of the same
Class and aggregate Percentage Interest.

          At the option of a Certificateholder, Certificates may be exchanged
for other Certificates of the same Class in authorized denominations and
evidencing the same aggregate Percentage Interest upon surrender of the
Certificates to be exchanged at the office or agency of the Trustee. Whenever
any Certificates are so surrendered for exchange, the Trustee shall execute,
authenticate, and deliver the Certificates which the Certificateholder making
the exchange is entitled to receive. Every Certificate presented or surrendered
for 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.

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

                                       95
<PAGE>

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

          (b) No transfer of a Private Certificate shall be made unless such
transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under said Act and such state securities laws. Except
in connection with any transfer of a Private Certificate by the Depositor to any
affiliate, in the event that a transfer is to be made in reliance upon an
exemption from the Securities Act and such laws, in order to assure compliance
with the Securities Act and such laws, the Certificateholder desiring to effect
such transfer and such Certificateholder's prospective transferee shall each
certify to the Trustee in writing the facts surrounding the transfer in
substantially the form set forth in Exhibit J (the "Transferor Certificate") and
(i) deliver a letter in substantially the form of either (A) Exhibit K (the
"Investment Letter") provided that all of the Class X Certificates of a Class
shall be transferred to one investor or the Depositor otherwise consents to such
transfer, or (B) Exhibit L (the "Rule 144A Letter") or (ii) there shall be
delivered to the Trustee at the expense of the transferor an Opinion of Counsel
that such transfer may be made pursuant to an exemption from the Securities Act.
The Depositor shall provide to any Holder of a Private Certificate and any
prospective transferee designated by any such Holder, information regarding the
related Certificates and the Mortgage Loans and such other information as shall
be necessary to satisfy the condition to eligibility set forth in Rule
144A(d)(4) for transfer of any such Certificate without registration thereof
under the Securities Act pursuant to the registration exemption provided by Rule
144A. The Trustee and the Servicer shall cooperate with the Depositor in
providing the Rule 144A information referenced in the preceding sentence,
including providing to the Depositor such information regarding the
Certificates, the Mortgage Loans and other matters regarding the Trust Fund as
the Depositor shall reasonably request to meet its obligation under the
preceding sentence. Each Holder of a Private Certificate desiring to effect such
transfer shall, and does hereby agree to, indemnify the Trustee, the Depositor,
the Seller and the Servicer against any liability that may result if the
transfer is not so exempt or is not made in accordance with such federal and
state laws.

          No transfer of an ERISA-Restricted Certificate shall be made unless
the Trustee shall have received either (i) a representation from the transferee
of such Certificate, acceptable to and in form and substance satisfactory to the
Trustee (in the event such Certificate is a Private Certificate or a Residual
Certificate, such requirement is satisfied only by the Trustee's receipt of a
representation letter from the transferee substantially in the form of Exhibit K
or Exhibit L, as applicable), to the effect that such transferee is not an
employee benefit plan or arrangement subject to Section 406 of ERISA or a plan
subject to Section 4975 of the Code, nor a person acting on behalf of any such
plan or arrangement nor using the assets of any such plan or arrangement to
effect such transfer or (ii) in the case of any such ERISA-Restricted
Certificate presented for registration in the name of an employee benefit plan
subject to ERISA, or a plan or arrangement subject to Section 4975 of the Code
(or comparable provisions of any subsequent enactments), or a trustee of any
such plan or any other person acting on behalf of any such plan or arrangement
or using such plan's or arrangement's assets, an Opinion of Counsel satisfactory
to the Trustee, which Opinion of Counsel shall not be an expense of either the
Trustee or the Trust Fund, addressed to the Trustee, to the effect that the
purchase or holding of such ERISA-Restricted Certificate will not result in the
assets of the Trust Fund being deemed to be "plan assets" and subject to the
prohibited transaction provisions of ERISA and the Code and will not subject the
Trustee or the Servicer to any obligation in addition

to those expressly undertaken in this Agreement or to any liability. For
purposes of the preceding sentence, with respect to an ERISA-Restricted
Certificate that is not a Private Certificate or a Residual Certificate, in the
event the representation letter referred to in the preceding sentence is not
furnished, such representation shall be deemed to have been made to the Trustee
by the ts (including an initial acquiror's) acceptance of the ERISA-Restricted
Certificates. Notwithstanding anything else to the contrary herein, any
purported transfer of an ERISA-Restricted Certificate to or on behalf of an
employee benefit plan subject to ERISA or to the Code without the delivery to
the Trustee of an Opinion of Counsel satisfactory to the Trustee as described
above shall be void and of no effect.

          To the extent permitted under applicable law (including, but not
limited to, ERISA), the Trustee shall be under no liability to any Person for
any registration of transfer of any ERISA- Restricted Certificate that is in
fact not permitted by this Section 5.02(b) or for making any payments due on
such Certificate to the Holder thereof or taking any other action with respect
to such Holder under the provisions of this Agreement so long as the transfer
was registered by the Trustee in accordance with the foregoing requirements.

          (c) Each Person who has or who acquires any Ownership Interest in a
Residual Certificate shall be deemed by the acceptance or acquisition of such
Ownership Interest to have agreed to be bound by the following provisions, and
the rights of each Person acquiring any Ownership Interest in a Residual
Certificate are expressly subject to the following provisions:

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

          (ii) No Ownership Interest in a Residual Certificate may be registered
     on the Closing Date or thereafter transferred, and the Trustee shall not
     register the Transfer of any Residual Certificate unless, in addition to
     the certificates required to be delivered to the Trustee under subparagraph
     (b) above, the Trustee shall have been furnished with an affidavit (a
     "Transfer Affidavit") of the initial owner or the proposed transferee in
     the form attached hereto as Exhibit I.

          (iii) Each Person holding or acquiring any Ownership Interest in a
     Residual Certificate shall agree (A) to obtain a Transfer Affidavit from
     any other Person to whom such Person attempts to Transfer its Ownership
     Interest in a Residual Certificate, (B) to obtain a Transfer Affidavit from
     any Person for whom such Person is acting as nominee, trustee or agent in
     connection with any Transfer of a Residual Certificate and (C) not to
     Transfer its Ownership Interest in a Residual Certificate or to cause the
     Transfer of an Ownership Interest in a Residual Certificate to any other
     Person if it has actual knowledge that such Person is not a Permitted
     Transferee.

          (iv) Any attempted or purported Transfer of any Ownership Interest in
     a Residual Certificate in violation of the provisions of this Section
     5.02(c) shall be absolutely null and void and shall vest no rights in the
     purported Transferee. If any purported transferee shall become a Holder of
     a Residual Certificate in violation of the provisions of this Section

                                       97
<PAGE>

     5.02(c), then the last preceding Permitted Transferee shall be restored to
     all rights as Holder thereof retroactive to the date of 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 Section 5.02(b) and this
     Section 5.02(c) or for making any payments due on such Certificate to the
     Holder thereof or taking any other action with respect to such Holder under
     the provisions of this Agreement so long as the Transfer was registered
     after receipt of the related Transfer Affidavit, Transferor Certificate and
     either the Rule 144A Letter or the Investment Letter. The Trustee shall be
     entitled but not obligated to recover from any Holder of a Residual
     Certificate that was in fact not a Permitted Transferee at the time it
     became a Holder or, at such subsequent time as it became other than a
     Permitted Transferee, all payments made on such Residual Certificate at and
     after either such time. Any such payments so recovered by the Trustee shall
     be paid and delivered by the Trustee to the last preceding Permitted
     Transferee of such Certificate.

          (v) The Depositor shall use its best efforts to make available, upon
     receipt of written request from the Trustee, all information necessary to
     compute any tax imposed under Section 860E(e) of the Code as a result of a
     Transfer of an Ownership Interest in a Residual Certificate to any Holder
     who is not a Permitted Transferee.

          The restrictions on Transfers of a Residual Certificate set forth in
this Section 5.02(c) shall cease to apply (and the applicable portions of the
legend on a Residual Certificate may be deleted) with respect to Transfers
occurring after delivery to the Trustee of an Opinion of Counsel, which Opinion
of Counsel shall not be an expense of the Trust Fund, the Trustee, the Seller or
the Servicer, to the effect that the elimination of such restrictions will not
cause the Trust Fund hereunder to fail to qualify as a REMIC at any time that
the Certificates are outstanding or result in the imposition of any tax on the
Trust Fund, a Certificateholder or another Person. Each Person holding or
acquiring any Ownership Interest in a Residual Certificate hereby consents to
any amendment of this Agreement which, based on an Opinion of Counsel furnished
to the Trustee, is reasonably necessary (a) to ensure that the record ownership
of, or any beneficial interest in, a Residual Certificate is not transferred,
directly or indirectly, to a Person that is not a Permitted Transferee and (b)
to provide for a means to compel the Transfer of a Residual Certificate which is
held by a Person that is not a Permitted Transferee to a Holder that is a
Permitted Transferee.

          (d) The preparation and delivery of all certificates and opinions
referred to above in this Section 5.02 in connection with transfer shall be at
the expense of the parties to such transfers.

          (e) Except as provided below, the Book-Entry Certificates shall at all
times remain registered in the name of the Depository or its nominee and at all
times: (i) registration of the Certificates may not be transferred by the
Trustee except to another Depository; (ii) the Depository shall maintain
book-entry records with respect to the Certificate Owners and with respect to
ownership and transfers of such Book-Entry Certificates; (iii) ownership and
transfers of registration of the Book-Entry Certificates on the books of the
Depository shall be governed by applicable rules established by the Depository;
(iv) the Depository may collect its usual and customary fees, charges and
expenses from its Depository Participants; (v) the Trustee shall deal with the
Depository, Depository Participants and indirect participating firms as
representatives of the Certificate Owners of the Book-Entry Certificates for
purposes of exercising the rights of holders under this Agreement,

                                       98
<PAGE>

and requests and directions for and votes of such representatives shall not be
deemed to be inconsistent if they are made with respect to different Certificate
Owners; and (vi) the Trustee may rely and shall be fully protected in relying
upon information furnished by the Depository with respect to its Depository
Participants and furnished by the Depository Participants with respect to
indirect participating firms and persons shown on the books of such indirect
participating firms as direct or indirect Certificate Owners.

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

          If (x) (i) the Depository or the Depositor advises the Trustee in
writing that the Depository is no longer willing or able to properly discharge
its responsibilities as Depository, and (ii) the Trustee or the Depositor is
unable to locate a qualified successor, (y) the Depositor at its option advises
the Trustee in writing that it elects to terminate the book-entry system through
the Depository or (z) after the occurrence of an Event of Default, Certificate
Owners representing at least 51% of the Certificate Balance of the Book-Entry
Certificates together advise the Trustee and the Depository through the
Depository Participants in writing that the continuation of a book-entry system
through the Depository is no longer in the best interests of the Certificate
Owners, the Trustee shall notify all Certificate Owners, through the Depository,
of the occurrence of any such event and of the availability of definitive,
fully-registered Certificates (the "Definitive Certificates") to Certificate
Owners requesting the same. Upon surrender to the Trustee of the related Class
of Certificates by the Depository, accompanied by the instructions from the
Depository for registration, the Trustee shall issue the Definitive
Certificates. None of the Sellers, the Servicer, the Depositor or the Trustee
shall be liable for any delay in delivery of such instruction and each may
conclusively rely on, and shall be protected in relying on, such instructions.
The Depositor shall provide the Trustee with an adequate inventory of
certificates to facilitate the issuance and transfer of Definitive Certificates.
Upon the issuance of Definitive Certificates all references herein to
obligations imposed upon or to be performed by the Depository 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 the Definitive Certificates as Certificateholders hereunder; provided
that the Trustee shall not by virtue of its assumption of such obligations
become liable to any party for any act or failure to act of the Depository.

          SECTION 5.03 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 Trustee such security or
indemnity as may be required by it to hold it harmless, then, in the absence of
notice to the Trustee that such Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute, countersign and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like Class, tenor and Percentage Interest. In connection with the
issuance of any new Certificate under this Section 5.03, the Trustee may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be

                                       99
<PAGE>

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 5.03 shall constitute complete and indefeasible
evidence of ownership, as if originally issued, whether or not the lost, stolen
or destroyed Certificate shall be found at any time.

          SECTION 5.04 Persons Deemed Owners.

          The Servicer, the Trustee and any agent of the 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 none of the Servicer, the
Trustee or any agent of the Servicer or the Trustee shall be affected by any
notice to the contrary.

          SECTION 5.05 Access to List of Certificateholders' Names and
                       Addresses.

          If three or more Certificateholders (a) request such information in
writing from the Trustee, (b) state that such Certificateholders desire to
communicate with other Certificateholders with respect to their rights under
this Agreement or under the Certificates, and (c) provide a copy of the
communication which such Certificateholders propose to transmit, or if the
Depositor or a Servicer shall request such information in writing from the
Trustee, then the Trustee shall, within ten Business Days after the receipt of
such request, provide the Depositor, the Servicer or such Certificateholders at
such recipients' expense the most recent list of the Certificateholders of such
Trust Fund held by the Trustee, if any. The Depositor and every
Certificateholder, by receiving and holding a Certificate, agree 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.

          SECTION 5.06 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 in New York, New York where Certificates
may be surrendered for registration of transfer or exchange. The Trustee
initially designates its Corporate Trust Office for such purposes. The Trustee
will give prompt written notice to the Certificateholders of any change in such
location of any such office or agency.

                   THE DEPOSITOR, THE SELLER AND THE SERVICER

          SECTION 6.01 Respective Liabilities of the Depositor, the Sellers and
                       the Servicer.

          The Depositor, the Seller and the 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.

          SECTION 6.02 Merger or Consolidation of the Depositor, the Seller or a
                       Servicer.

          The Depositor, the Seller and the Servicer will each keep in full
effect its existence, rights and franchises as a corporation under the laws of
the United States or under the laws of one of the states thereof or as a
federally chartered savings bank organized under the laws of the United States
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.
Notwithstanding the foregoing, the Seller or the Servicer may be merged or
consolidated into another Person in accordance with the following paragraph.

          Any Person into which the Depositor, the Seller or the Servicer may be
merged or consolidated, or any Person resulting from any merger or consolidation
to which the Depositor, the Seller or the Servicer shall be a party, or any
person succeeding to the business of the Depositor, the Seller or the Servicer,
shall be the successor of the Depositor, the Seller or the Servicer, as the case
may be, hereunder, without the execution or filing of any paper or any further
act on the part of any of the parties hereto, anything herein to the contrary
notwithstanding, provided, however, that the successor or surviving Person with
respect to a merger or consolidation of the Servicer shall be an institution
which is a Fannie Mae or Freddie Mac approved company in good standing. In
addition to the foregoing, there must be delivered to the Trustee a letter from
each of the Rating Agencies, to the effect that such merger, conversion or
consolidation of the Servicer will not result in a disqualification, withdrawal
or downgrade of the then current rating of any of the Certificates.

          SECTION 6.03 Limitation on Liability of the Depositor, the Seller, the
                       Servicer and Others.

          None of the Depositor, the Seller, the Servicer nor any of the
directors, officers, employees or agents of the Depositor, the Seller or the
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 Depositor, the Seller, the Servicer or any such
Person against any breach of representations or warranties made by it herein or
protect the Depositor, the Seller, the 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

                                      101
<PAGE>

of obligations and duties hereunder. The Depositor, the Seller, the Servicer and
any director, officer, employee or agent of the Depositor, the Seller or the
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 Depositor, the Seller, the Trustee, the Servicer and any director, officer,
employee or agent of the Depositor, the Seller, the Trustee, or the Servicer
shall be indemnified by the Trust Fund out of the Collection Account 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 its duties hereunder or by reason of
reckless disregard of obligations and duties hereunder. None of the Depositor,
the Seller or the Servicer shall be under any obligation to appear in, prosecute
or defend any legal action that is not incidental to its respective duties
hereunder and which in its opinion may involve it in any expense or liability;
provided, however, that any of the Depositor, the Seller or the Servicer may in
its discretion undertake any such action that it may deem necessary or desirable
in respect of this Agreement and the rights and duties of the parties hereto and
interests of the Trustee and the Certificateholders hereunder. In such event,
the legal expenses and costs of such action and any liability resulting
therefrom shall be expenses, costs and liabilities of the Trust Fund, and the
Depositor, the Seller and the Servicer shall be entitled to be reimbursed
therefor out of the Collection Account. The Servicer's right to indemnity or
reimbursement pursuant to this Section 6.03 shall survive the resignation or
termination of the Servicer as set forth herein.

          SECTION 6.04 Limitation on Resignation of the Servicer.

          (a) Subject to Section 6.04(b) below, the Servicer shall not resign
from the obligations and duties hereby imposed on it except (a)(i) upon
appointment, pursuant to the provisions of Section 7.02, of a successor servicer
which (x) has a net worth of not less than $10,000,000 and (y) is a Fannie Mae
or Freddie Mac approved company in good standing and (ii) receipt by the Trustee
of a letter from each Rating Agency that such a resignation and appointment will
not result in a qualification, withdrawal or downgrading of the then current
rating of any of the Certificates, or (b) upon determination that its duties
hereunder are no longer permissible under applicable law. Any such determination
under clause (b) permitting the resignation of the Servicer shall be evidenced
by an Opinion of Counsel to such effect delivered to the Trustee. No such
resignation shall become effective until the Trustee or a successor servicer
shall have assumed the Servicer's responsibilities, duties, liabilities and
obligations hereunder and the requirements of Section 7.02 have been satisfied.

          (b) Notwithstanding the foregoing, at the Seller's request, so long as
it is the owner of the servicing rights, Wilshire shall resign upon the Seller's
selection and appointment of a successor servicer; provided that the Seller
delivers to the Trustee the letter required by Section 6.04(a)(ii) above.

                                     DEFAULT

          SECTION 7.01 Events of Default.

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

          (i) any failure by the Servicer to make any deposit or payment
     required pursuant to this Agreement which continues unremedied for a period
     of one Business Day (or, in the case of any such failure to make any
     deposit or payment due to any outbreak or escalation of hostilities,
     declaration by the United States of a national emergency or war or other
     calamity or crisis or act of god, for a period of three Business Days)
     after the date upon which written notice of such failure, requiring the
     same to be remedied, shall have been given to the Servicer by the Trustee
     or the Depositor, or to the Servicer and the Trustee by the Holders of
     Certificates having not less than 25% of the Voting Rights evidenced by the
     Certificates; or

          (ii) any failure by the Servicer duly to observe or perform in any
     material respect any other of the covenants or agreements on the part of
     the Servicer set forth in this Agreement, which failure or breach (a)
     materially affects the rights of the Certificateholders and (b) continues
     unremedied for a period of 30 days after the date on which written notice
     of such failure or breach, requiring the same to be remedied, shall have
     been given to the Servicer by the Trustee or the Depositor, or to the
     Servicer and the Trustee by the Holders of Certificates having not less
     than 25% of the Voting Rights evidenced by the Certificates; or

          (iii) if a representation or warranty set forth in Section 2.03(b) or
     (c), as applicable, 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, within 30 days (or, if such breach is not capable of
     being cured within 30 days and provided that the Servicer believes in good
     faith that such breach can be cured and is diligently pursuing the cure
     thereof, within 90 days) after the date on which written notice thereof
     shall have been given to the Servicer by the Trustee for the benefit of the
     Certificateholders or by the Depositor; or

          (iv) failure by the Servicer to maintain, if required, its license to
     do business in any jurisdiction where the related Mortgaged Property is
     located; or

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

                                      103
<PAGE>

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

          (vii) any failure of the Servicer to make any Advance, to the extent
     required under Section 4.01 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, which failure continues unremedied after the close
     of business on the Business Day immediately preceding the related
     Distribution Date; or

          (viii) the 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, bankruptcy or
     reorganization statute, make an assignment for the benefit of its
     creditors, voluntarily suspend payment of its obligations or cease its
     normal business operations for three Business Days; or

          (ix) (a) either (I) the servicer rankings or ratings of the Servicer
     are downgraded two or more levels below the level in effect on the Closing
     Date by one or more of the Rating Agencies rating the Certificates or (II)
     the servicer rankings or ratings for the Servicer are downgraded to "below
     average" status by one or more of the Rating Agencies rating the
     Certificates or (b) one or more Classes of the Certificates are downgraded
     or placed on negative watch due in whole or in part to the performance or
     servicing of the Servicer.

          Other than an Event of Default resulting from a failure of the
Servicer to make any Advance, if an Event of Default described in clauses (i)
through (viii) of this Section shall occur, then, and in each and every such
case, so long as such Event of Default shall not have been remedied, the Trustee
may, or at the direction of the Holders of Certificates evidencing not less than
51% of the Voting Rights evidenced by the Certificates, the Trustee shall by
notice in writing to the Servicer (with a copy to each Rating Agency), terminate
all of the rights and obligations of the Servicer under this Agreement and in
and to the related Mortgage Loans and the proceeds thereof, other than its
rights as a Certificateholder hereunder and its rights to reimbursement for
Advances or other advances previously made pursuant to this Agreement. If an
Event of Default results from the failure of the Servicer to make an Advance,
the Trustee shall prior to the Distribution Date occurring in the succeeding
calendar month, by notice in writing to the Servicer and the Depositor (with a
copy to each Rating Agency), terminate all of the rights and obligations of the
Servicer under this Agreement prior to the Distribution Date occurring in the
succeeding calendar month and in and to the related Mortgage Loans and the
proceeds thereof, other than its rights as a Certificateholder hereunder. If an
Event of Default described in clause (ix) of this Section occurs, the Trustee
shall, at the direction of the Seller, by notice in writing to the Servicer,
terminate all of the rights and obligations of the Servicer under this Agreement
(other than rights to reimbursement for Advances and Servicing Advances
previously made, as provided in Section 3.08) and shall appoint as successor
Servicer the entity selected by the Seller in accordance with Section 7.02;
provided the Seller shall first furnish to the Trustee a letter from each Rating
Agency that the appointment of such successor will not result in a downgrading
of the rating of any of the Certificates.

                                      104
<PAGE>

          Upon receipt by the Servicer of such written notice of termination,
all authority and power of the Servicer under this Agreement, whether with
respect to the Mortgage Loans or otherwise, shall pass to and be vested in the
Trustee or its nominee. Upon written request from the Trustee, the Servicer
shall prepare, execute and deliver to the successor entity designated by the
Trustee any and all documents and other instruments, place in such successor's
possession all Mortgage Files, and do or cause to be done all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, including but not limited to the transfer and endorsement or
assignment of the Mortgage Loans and related documents, at the Servicer's sole
expense. The Servicer shall cooperate with the Trustee and such successor in
effecting the termination of the 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 Servicer to the Collection Account or Escrow Account or thereafter received
with respect to the Mortgage Loans. The Trustee shall thereupon make any
Advance. The Trustee is hereby authorized and empowered to execute and deliver,
on behalf of the Servicer, as attorney-in-fact or otherwise, any and all
documents and other instruments, and to do or accomplish all other acts or
things necessary or appropriate to effect the purposes of such notice of
termination, whether to complete the transfer and endorsement or assignment of
the related Mortgage Loans and related documents, or otherwise.

          SECTION 7.02 Trustee to Act; Appointment of Successor.

          On and after the time the Servicer receives a notice of termination
pursuant to Section 7.01 of this Agreement or the resignation of the Servicer
pursuant to Section 6.04, the Trustee shall, subject to and to the extent
provided herein, be the successor to the Servicer, but only in its capacity as
servicer under this Agreement, and not in any other, and the transactions set
forth herein and shall be subject to all the responsibilities, duties and
liabilities relating thereto placed on the Servicer by the terms and provisions
hereof and applicable law including the obligation to make Advances pursuant to
Section 4.01. As compensation therefor, the Trustee shall be entitled to all
funds relating to the related Mortgage Loans that the Servicer would have been
entitled to charge to the Collection Account, provided that the terminated
Servicer shall nonetheless be entitled to payment or reimbursement as provided
in Section 3.08 to the extent that such payment or reimbursement relates to the
period prior to termination of the Servicer. Notwithstanding the foregoing, if
the Trustee has become the successor to the Servicer in accordance with Section
7.01, the Trustee may, if it shall be unwilling to so act, or shall, if it is
prohibited by applicable law from making Advances pursuant to 4.01 hereof, or if
it is otherwise 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 by each Rating Agency, as the successor to the Servicer hereunder
in the assumption of all or any part of the responsibilities, duties or
liabilities of the Servicer hereunder. Any successor to the Servicer shall be an
institution which is a Fannie Mae or Freddie Mac approved seller/servicer for
first and second loans in good standing, which has a net worth of at least
$10,000,000, which is willing to service the related Mortgage Loans and which
executes and delivers to the Depositor and the Trustee an agreement accepting
such delegation and assignment, containing an assumption by such Person of the
rights, powers, duties, responsibilities, obligations and liabilities of the
Servicer (other than liabilities of the Servicer under Section 6.03 hereof
incurred prior to termination of the Servicer under Section 7.01 hereunder),
with like effect as if originally named as a party to this Agreement; provided
that each Rating Agency

                                      105
<PAGE>

acknowledges that its rating of the Certificates in effect immediately prior to
such assignment and delegation will not be qualified, withdrawn or downgraded as
a result of such assignment and delegation. Pending appointment of a successor
to the Servicer hereunder, the Trustee, unless the Trustee is prohibited by law
from so acting, shall, subject to the limitations described herein, act in such
capacity as hereinabove provided. In connection with such appointment and
assumption, the Trustee may make such arrangements for the compensation of such
successor out of payments on the related Mortgage Loans as it and such successor
shall agree; provided, however, that no such compensation shall be in excess of
the Servicing Fee. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession. Neither the Trustee nor any other successor servicer shall be deemed
to be in default by reason of any failure to make, or any delay in making, any
distribution hereunder or any portion thereof or any failure to perform, or any
delay in performing, any duties or responsibilities hereunder, in either case
caused by the failure of the Servicer to deliver or provide, or any delay in
delivering or providing, any cash, information, documents or records to it.

          In connection with the termination or resignation of the Servicer
hereunder, either (i) the successor servicer, including the Trustee if the
Trustee is acting as successor Servicer, shall represent and warrant that it is
a member of MERS in good standing and shall agree to comply in all material
respects with the rules and procedures of MERS in connection with the servicing
of the Mortgage Loans that are registered with MERS, in which case the
predecessor Servicer shall cooperate with the successor Servicer in causing MERS
to revise its records to reflect the transfer of servicing to the successor
Servicer as necessary under MERS' rules and regulations, or (ii) the predecessor
Servicer shall cooperate with the successor Servicer in causing MERS to execute
and deliver an assignment of Mortgage in recordable form to transfer the
Mortgage from MERS to the Trustee and to execute and deliver such other notices,
documents and other instruments as may be necessary or desirable to effect a
transfer of such Mortgage Loan or servicing of such Mortgage Loan on the MERS(R)
System to the successor Servicer. The predecessor Servicer shall file or cause
to be filed any such assignment in the appropriate recording office. The
predecessor Servicer shall bear any and all fees of MERS, costs of preparing any
assignments of Mortgage, and fees and costs of filing any assignments of
Mortgage that may be required under this subsection.

          Any successor to the Servicer shall give notice to the Mortgagors of
such change of servicer and shall, during the term of its service as servicer,
maintain in force the policy or policies that the Servicer is required to
maintain pursuant to this Agreement.

          SECTION 7.03 Notification to Certificateholders.

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

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

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

          SECTION 8.01 Duties of the Trustee.

          The Trustee, prior to the occurrence of an Event of Default and after
the curing of all Events of Default that may have occurred, shall undertake 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, 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.

          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 are in
the form required by this Agreement; provided, however, that the Trustee shall
not be responsible for the accuracy or content of any such resolution,
certificate, statement, opinion, report, document, order or other instrument.

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

          (i) unless an Event of Default actually known to the Trustee shall
     have occurred and be continuing, the duties and obligations of the Trustee
     shall be determined solely by the express provisions of this Agreement, the
     Trustee shall not be liable except for the performance of such duties and
     obligations as are specifically set forth in this Agreement, no implied
     covenants or obligations shall be read into this Agreement against the
     Trustee and 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 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 liable for an error of judgment made in
     good faith by a Responsible Officer or Responsible Officers of the Trustee,
     unless it shall be finally proven that the Trustee was negligent in
     ascertaining the pertinent facts; and

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

          SECTION 8.02 Certain Matters Affecting the Trustee.

          Except as otherwise provided in Section 8.01:

          (i) the Trustee may request and conclusively rely upon and shall be
     protected in acting or refraining from acting upon any resolution,
     Officers' Certificate, certificate of auditors or any other certificate,
     statement, instrument, opinion, report, notice, request, consent, order,
     appraisal, bond or other paper or document believed by it to be genuine and
     to have been signed or presented by the proper party or parties and the
     Trustee shall have no responsibility to ascertain or confirm the
     genuineness of any signature of any such party or parties;

          (ii) the Trustee may consult with counsel, financial advisers or
     accountants and the advice of any such counsel, financial advisers or
     accountants and any Opinion of Counsel shall be full and complete
     authorization and protection in respect of any action taken or suffered or
     omitted by it hereunder in good faith and in accordance with such advice or
     Opinion of Counsel;

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

          (iv) 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 Rights
     allocated to each Class of Certificates;

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

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

          (vii) the Trustee shall not be liable for any loss on any investment
     of funds pursuant to this Agreement (other than as issuer of the investment
     security);

          (viii) the Trustee shall not be deemed to have knowledge of an Event
     of Default until a Responsible Officer of the Trustee shall have received
     written notice thereof; and

          (ix) the Trustee shall be under no obligation to exercise any of the
     trusts, rights 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

                                      108
<PAGE>

     Certificateholders, pursuant to the provisions of this Agreement, unless
     such Certificateholders shall have offered to the Trustee reasonable
     security or indemnity satisfactory to the Trustee against the costs,
     expenses and liabilities which may be incurred therein or thereby.

          SECTION 8.03 Trustee Not Liable for Certificates or Mortgage Loans.

          The recitals contained herein and in the Certificates shall be taken
as the statements of the Depositor or the Seller, as the case may be, and the
Trustee assumes no responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Agreement or of the
Certificates or of any Mortgage Loan or related document, or of MERS or the
MERS(R) System, other than with respect to the Trustee's execution and
countersignature of the Certificates. The Trustee shall not be accountable for
the use or application by the Depositor or a Servicer of any funds paid to the
Depositor or a Servicer in respect of the Mortgage Loans or deposited in or
withdrawn from the Collection Account by the Depositor or the Servicer.

          SECTION 8.04 Trustee May Own Certificates.

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Certificates and may transact business with the Depositor,
the Seller, the Servicer and their affiliates, with the same rights as it would
have if it were not the Trustee.

          SECTION 8.05 Trustee's Fees and Expenses.

          The Trustee, as compensation for its activities hereunder, shall be
entitled to withdraw from the Certificate Account on each Distribution Date
prior to making distributions pursuant to Section 4.02 an amount equal to the
Trustee Fee for such Distribution Date. The Trustee and any director, officer,
employee or agent of the Trustee shall be indemnified by the Depositor and the
Servicer, to the extent such indemnity related to the failure of the Servicer to
perform its servicing obligations in accordance with this Agreement, and held
harmless against any loss, liability or expense (including reasonable attorney's
fees and expenses) (i) incurred in connection with any claim or legal action
relating to (a) this Agreement, (b) the Custodial Agreement, (c) the
Certificates, or (d) the performance of any of the Trustee's duties hereunder,
other than any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or negligence in the performance of any of the Trustee's
duties hereunder or incurred by reason of any action of the Trustee taken at the
direction of the Certificateholders and (ii) resulting from any error in any tax
or information return prepared by the Servicer. Such indemnity shall survive the
termination of this Agreement or the resignation or removal of the Trustee
hereunder. Without limiting the foregoing, the Depositor covenants and agrees,
except as otherwise agreed upon in writing by the Depositor and the Trustee, and
except for any such expense, disbursement or advance as may arise from the
Trustee's negligence, bad faith or willful misconduct, to pay or reimburse the
Trustee, for all reasonable expenses, disbursements and advances incurred or
made by the Trustee in accordance with any of the provisions of this Agreement
with respect to: (A) the reasonable compensation and the expenses and
disbursements of its counsel not associated with the closing of the issuance of
the Certificates, (B) the reasonable compensation, expenses and disbursements of
any accountant, engineer or appraiser that is not regularly employed by the
Trustee, to the extent that the Trustee must engage

                                      109
<PAGE>

such persons to perform acts or services hereunder and (C) printing and
engraving expenses in connection with preparing any Definitive Certificates.
Except as otherwise provided herein, the Trustee shall not be entitled to
payment or reimbursement for any routine ongoing expenses incurred by the
Trustee in the ordinary course of its duties as Trustee, Registrar or agent for
the Tax Matters Person hereunder or for any other expenses.

          SECTION 8.06 Eligibility Requirements for the Trustee and Custodian.

          The Trustee hereunder shall at all times be a corporation or
association organized and doing business under the laws of a state or the United
States of America, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, subject
to supervision or examination by federal or state authority and with a credit
rating which would not cause either of the Rating Agencies to reduce their
respective then current Ratings of the Certificates (or having provided such
security from time to time as is sufficient to avoid such reduction) as
evidenced in writing by each Rating Agency. If such corporation or association
publishes reports of condition at least annually, pursuant to law or to the
requirements of the aforesaid supervising or examining authority, then for the
purposes of this Section 8.06 the combined capital and surplus of such
corporation or association shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. In
case at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 8.06, the Trustee shall resign immediately in the
manner and with the effect specified in Section 8.07. The entity serving as
Trustee may have normal banking and trust relationships with the Depositor and
its affiliates or a Servicer and its affiliates; provided, however, that such
entity cannot be an affiliate of the Seller, the Depositor or a Servicer other
than the Trustee in its role as successor to a Servicer.

          SECTION 8.07 Resignation and Removal of the Trustee.

          The Trustee may at any time resign and be discharged from the trusts
hereby created by giving written notice of resignation to the Depositor, the
Seller, the Servicer and each Rating Agency not less than 60 days before the
date specified in such notice, when, subject to Section 8.08, such resignation
is to take effect, and acceptance by a successor trustee in accordance with
Section 8.08 meeting the qualifications set forth in Section 8.06. If no
successor trustee meeting such qualifications shall have been so appointed and
have accepted appointment within 30 days after the giving of such notice of
resignation or removal (as provided below), the resigning or removed Trustee may
petition any court of competent jurisdiction for the appointment of a successor
trustee.

          If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 8.06 and shall fail to resign after written
request thereto by the Depositor, or if at any time the Trustee shall become
incapable of acting, or shall be adjudged as 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, or a tax
is imposed with respect to the Trust Fund by any state in which the Trustee or
the Trust Fund is located and the imposition of such tax would be avoided by the
appointment of a different trustee, then the Depositor may remove the Trustee
and appoint a successor trustee by written instrument, in triplicate, one copy
of which shall be delivered to the Trustee, one copy to the Servicer and the
Seller and one copy to the successor trustee.

                                      110
<PAGE>

          The Holders of Certificates entitled to at least 51% of the Voting
Rights may at any time remove the Trustee and appoint a successor trustee by
written instrument or instruments, in triplicate, signed by such Holders or
their attorneys-in-fact duly authorized, one complete set of which shall be
delivered by the successor Trustee to the Servicer and the Seller, one complete
set to the Trustee so removed and one complete set to the successor so
appointed. Notice of any removal of the Trustee shall be given to each Rating
Agency by the successor trustee. All costs and expenses incurred by the Trustee
in connection with the removal of the Trustee without cause shall be reimbursed
to the Trustee from amounts on deposit in the Collection Account.

          Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 8.07 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 8.08.

          SECTION 8.08 Successor Trustee.

          Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Depositor and to its predecessor trustee
and the Servicer and the Seller 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 Depositor, the Servicer and the predecessor trustee
shall execute and deliver such instruments and do such other things as may
reasonably be required for more fully and certainly vesting and confirming in
the successor trustee all such rights, powers, duties, and obligations.

          No successor trustee shall accept appointment as provided in this
Section 8.08 unless at the time of such acceptance such successor trustee shall
be eligible under the provisions of Section 8.06 and its appointment shall not
adversely affect the then current rating of the Certificates.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 8.08, the Depositor shall mail notice of the succession of such
trustee hereunder to all Holders of Certificates. If the Depositor fails to mail
such notice within 10 days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Depositor.

          SECTION 8.09 Merger or Consolidation of the Trustee.

          Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to the business of the Trustee, shall be the successor of
the Trustee hereunder, provided that such corporation shall be eligible under
the provisions of Section 8.06 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.

                                      111
<PAGE>

          SECTION 8.10 Appointment of Co-Trustee or Separate Trustee.

          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 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 Certificateholders, such title to the Trust Fund or any part
thereof, whichever is applicable, and, subject to the other provisions of this
Section 8.10, such powers, duties, obligations, rights and trusts as the
Servicer and the Trustee may consider necessary or desirable. If the Servicer
shall not have joined in such appointment within 15 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 8.06 and no
notice to Certificateholders of the appointment of any co-trustee or separate
trustee shall be required under Section 8.08.

          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) To the extent necessary to effectuate the purposes of this Section
     8.10, all rights, powers, duties and obligations conferred or imposed upon
     the Trustee shall be conferred or imposed upon and exercised or 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 (whether as Trustee hereunder or as successor
     to the Servicer hereunder), the Trustee shall be incompetent or unqualified
     to perform such act or acts, in which event such rights, powers, duties and
     obligations (including the holding of title to the applicable 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 such appointment
     shall not, and shall not be deemed to, constitute any such separate trustee
     or co-trustee as agent of the Trustee;

          (iii) The Trustee may at any time accept the resignation of or remove
     any separate trustee or co-trustee; and

          (iv) The Depositor, and not the Trustee, shall be liable for the
     payment of reasonable compensation, reimbursement and indemnification to
     any such separate trustee or co-trustee.

          Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the separate trustees and co-trustees, when
and as effectively as if given to each of

                                      112
<PAGE>

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

          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.

          SECTION 8.11 Tax Matters.

                  It is intended that the assets with respect to which the REMIC
elections are to be made, as set forth in the Preliminary Statement, shall
constitute, and that the conduct of matters relating to each such segregated
pool of assets shall be such as to qualify such assets as, a "real estate
mortgage investment conduit" as defined in and in accordance with the Trust Fund
Provisions. In furtherance of such intention, the Trustee covenants and agrees
that it shall act as agent (and the Trustee is hereby appointed to act as agent)
for the Tax Matters Person and on behalf of the Trust Fund and that in such
capacity it shall: (a) prepare and file, or cause to be prepared and filed, in a
timely manner, a U.S. Real Estate Mortgage Investment Conduit Income Tax Return
(Form 1066 or any successor form adopted by the Internal Revenue Service) and
prepare and file or cause to be prepared and filed with the Internal Revenue
Service and applicable state or local tax authorities income tax or information
returns for each taxable year with respect to each of REMIC 1, REMIC 2 and REMIC
3 containing such information and at the times and in the manner as may be
required by the Code or state or local tax laws, regulations, or rules, and
furnish or cause to be furnished to Certificateholders the schedules, statements
or information at such times and in such manner as may be required thereby; (b)
within thirty days of the Closing Date, furnish or cause to be furnished to the
Internal Revenue Service, on Forms 8811 or as otherwise may be required by the
Code, the name, title, address, and telephone number of the person that the
holders of the Certificates may contact for tax information relating thereto,
together with such additional information as may be required by such form, and
update such information at the time or times in the manner required by the Code;
(c) make or cause to be made elections that the assets of each of REMIC 1, REMIC
2 and REMIC 3 be treated as a REMIC on the federal tax return for its first
taxable year (and, if necessary, under applicable state law); (d) prepare and
forward, or cause to be prepared and forwarded, to the Certificateholders and to
the Internal Revenue Service and, if necessary, state tax authorities, all
information returns and reports as and when required to be provided to them in
accordance with the REMIC Provisions, including without limitation, the
calculation of any original issue discount using the Prepayment Assumption; (e)
provide information necessary for the computation of tax imposed on the transfer
of a Residual Certificate to a Person that is not a Permitted Transferee, or an
agent (including a broker, nominee or other middleman) of a Non-Permitted
Transferee, or a pass-th entity in which a Non-Permitted Transferee is the
record holder of an interest (the reasonable cost

                                      113
<PAGE>

of computing and furnishing such information may be charged to the Person liable
for such tax); (f) to the extent that they are under its control, conduct
matters relating to such assets at all times that any Certificates are
outstanding so as to maintain the status of REMIC 1, REMIC 2 and REMIC 3 as a
REMIC under the REMIC Provisions; (g) not knowingly or intentionally take any
action or omit to take any action that would cause the termination of the REMIC
status of REMIC 1, REMIC 2 or REMIC 3; (h) pay, from the sources specified in
the fourth paragraph of this Section 8.11, the amount of any federal or state
tax, including prohibited transaction taxes as described below, imposed on the
Trust Fund prior to its termination when and as the same shall be due and
payable (but such obligation shall not prevent the Trustee or any other
appropriate Person from contesting any such tax in appropriate proceedings and
shall not prevent the Trustee from withholding payment of such tax, if permitted
by law, pending the outcome of such proceedings); (i) ensure that federal, state
or local income tax or information returns shall be signed by the Trustee or
such other person as may be required to sign such returns by the Code or state
or local laws, regulations or rules; (j) maintain records relating to the Trust
Fund, including but not limited to the income, expenses, assets and liabilities
thereof and the fair market value and adjusted basis of the assets determined at
such intervals as may be required by the Code, as may be necessary to prepare
the foregoing returns, schedules, statements or information; and (k) as and when
necessary and appropriate, represent the Trust Fund in any administrative or
judicial proceedings relating to an examination or audit by any governmental
taxing authority, request an administrative adjustment as to any taxable year of
the Trust Fund, enter into settlement agreements with any governmental taxing
agency, extend any statute of limitations relating to any tax item of the Trust
Fund, and otherwise act on behalf of the Trust Fund in relation to any tax
matter or controversy involving it.

          To the extent that they are under its control, the Servicer shall
conduct matters relating to the assets of each REMIC at all times that any
Certificates are outstanding so as to maintain the status of REMIC 1, REMIC 2
and REMIC 3 as a REMIC under the REMIC Provisions. No Servicer shall knowingly
or intentionally take any action that would cause the termination of the REMIC
status of REMIC 1, REMIC 2 or REMIC 3.

          In order to enable the Trustee to perform its duties as set forth
herein, the Depositor shall provide, or cause to be provided, to the Trustee
within ten (10) days after the Closing Date all information or data that the
Trustee requests in writing and 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. Thereafter, the Depositor shall provide
to the Trustee promptly upon written 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. The
Depositor hereby indemnifies the Trustee for any losses, liabilities, damages,
claims or expenses of the Trustee arising from any errors or miscalculations of
the Trustee that result from any failure of the Depositor to provide, or to
cause to be provided, accurate information or data to the Trustee on a timely
basis.

          In the event that any tax is imposed on "prohibited transactions" of
the Trust Fund as defined in Section 860F(a)(2) of the Code, on the "net income
from foreclosure property" of the Trust Fund as defined in Section 860G(c) of
the Code, on any contribution to the Trust Fund after the Startup Day pursuant
to Section 860G(d) of the Code, or any other tax is imposed, if not paid as
otherwise provided for herein, such tax shall be paid by (i) the Trustee, if any
such other tax arises

                                      114
<PAGE>

out of or results from a breach by the Trustee of any of its obligations under
this Agreement, (ii) the Servicer or the Seller, in the case of any such minimum
tax, if such tax arises out of or results from a breach by the Servicer or the
Seller of any of their obligations under this Agreement or (iii) the Seller, if
any such tax arises out of or results from the Seller's obligation to repurchase
a related Mortgage Loan pursuant to Section 2.02 or 2.03 or (iv) in all other
cases, or in the event that the Trustee, the related Servicer or Seller fails to
honor its obligations under the preceding clauses (i), (ii) or (iii), any such
tax will be paid with amounts otherwise to be distributed to the
Certificateholders, as provided in Section 4.02.

          Neither the Servicer nor the Trustee shall enter into any arrangement
by which any of REMIC 1, REMIC 2 or REMIC 3 will receive a fee or other
compensation for services nor permit any of REMIC 1, REMIC 2 or REMIC 3 to
receive any income from assets other than "qualified mortgages" as defined in
Section 860G(a)(3) of the Code or "permitted investments" as defined in Section
860G(a)(5) of the Code.

          SECTION 8.12 Commission Reporting.

          (a) The Trustee and the Servicer shall reasonably cooperate with the
Depositor in connection with the Trust's satisfying the reporting requirements
under the Exchange Act. The Trustee shall prepare on behalf of the Depositor any
Forms 8-K and 10-K customary for similar securities as required by the Exchange
Act and the rules and regulations of the Commission thereunder, and the
Depositor shall sign and the Trustee shall file (via EDGAR) such Forms on behalf
of the Depositor. The Depositor hereby grants to the Trustee a limited power of
attorney to execute and file each such document on behalf of the Depositor. Such
power of attorney shall continue until the earlier of (i) receipt by the Trustee
from the Depositor of written termination of such power of attorney and (ii) the
termination of the Trust.

          (b) Each Form 8-K shall be filed by the Trustee within 15 days after
each Distribution Date, with a copy of the statement to the Certificateholders
for such Distribution Date as an exhibit thereto. Prior to March 31st of the
calendar year following the calendar year during which the Closing Date occurs
(or such earlier date as may be required by the Exchange Act and the rules and
regulations of the Commission), the Trustee shall file a Form 10-K, in substance
as required by applicable law or applicable Commission staff's interpretations.
Such Form 10-K shall include as exhibits, the Servicer's annual statement of
compliance described under Section 3.16 and the accountant's report described
under Section 3.17, in each case to the extent they have been timely delivered
to the Trustee. If they are not so timely delivered, the Trustee shall file an
amended Form 10-K including such documents as exhibits promptly after they are
delivered to the Trustee. The Trustee shall have no liability with respect to
any failure to properly or timely prepare or file such periodic reports
resulting from or relating to the Trustee's inability or failure to obtain any
information not resulting from its own negligence or willful misconduct. The
Form 10-K shall also include a certification in the form attached hereto as
Exhibit W (the "Depositor Certification"), which shall be signed by the senior
officer of the Depositor in charge of securitization. The Trustee shall have no
responsibility to file any items other than those specified in this Section
8.12.

          (c) Not later than 15 calendar days before the date on which the
Depositor's annual report on Form 10-K is required to be filed in accordance
with the Exchange Act and the rules

                                      115
<PAGE>

and regulations of the Commission (or, if such day is not a Business Day, the
immediately preceding Business Day), the Trustee shall sign a certification in
the form attached hereto as Exhibit X (the "Trustee Certification") for the
benefit of the Depositor and its officers, directors and affiliates regarding
certain aspects of items 1 through 3 of the Depositor Certification. In
addition, the Trustee shall, subject to the provisions of Section 8.01 and 8.02
hereof, indemnify and hold harmless the Depositor and each Person, if any, who
"controls" the Depositor within the meaning of the Securities Act and its
officers, directors and affiliates from and against any losses, damages,
penalties, fines, forfeitures, reasonable and necessary legal fees and related
costs, judgments and other costs and expenses arising out of or based upon a
breach of the Trustee's obligations under this Section 8.12 or any inaccuracy
made in the Trustee Certification. If the indemnification provided for in this
Section 8.12(c) is unavailable or insufficient to hold harmless such Persons,
then the Trustee shall contribute to the amount paid or payable by such Persons
as a result of the losses, claims, damages or liabilities of such Persons in
such proportion as is appropriate to reflect the relative fault of the Depositor
on the one hand and the Trustee on the other. The Trustee acknowledges that the
Depositor is relying on the Trustee's performance of its obligations under this
Section 8.12 in order to perform its obligations under Section 8.12(b) above.

          (d) Not later than 15 calendar days before the date on which the
Depositor's annual report on Form 10-K is required to be filed in accordance
with the Exchange Act and the rules and regulations of the Commission (or, if
such day is not a Business Day, the immediately preceding Business Day), the
Servicer will deliver to the Depositor and the Trustee an Officer's Certificate
for the prior calendar year in substantially the form of Exhibit Y to this
Agreement. The Servicer agrees to indemnify and hold harmless the Depositor, the
Trustee and each Person, if any, who " the Depositor or the Trustee within the
meaning of the Securities Act and their respective officers, directors and
affiliates from and against any losses, damages, penalties, fines, forfeitures,
reasonable and necessary legal fees and related costs, judgments and other
costs, fees and expenses that such Person may sustain arising out of third party
claims based on (i) the failure of the Servicer to deliver or caused to be
delivered when required any Officer's Certificate pursuant to this Section
8.12(d), or (ii) any material misstatement or omission contained in any
Officer's Certificate provided pursuant to this Section 8.12(d). If an event
occurs that would otherwise result in an indemnification obligation under
clauses (i) or (ii) above, but the indemnification provided for in this Section
8.12(d) by the Servicer is unavailable or insufficient to hold harmless such
Persons, then the Servicer shall contribute to the amount paid or payable by
such Persons as a result of the losses, claims, damages or liabilities of such
Persons in such proportion as is appropriate to reflect the relative fault of
the Depositor or Trustee on the one hand and the Servicer on the other. The
Servicer acknowledges that the Depositor and the Trustee are relying on the
Servicer's performance of its obligations under this Agreement in order to
perform their respective obligations under this Section 8.12.

          (e) Upon any filing with the Commission, the Trustee shall promptly
deliver to the Depositor a copy of any executed report, statement or
information.

          (f) If the Commission issues additional interpretative guidance or
promulgates additional rules or regulations, or if other changes in applicable
law occur, that would require the reporting arrangements, or the allocation of
responsibilities with respect thereto, described in this Section 8.12, to be
conducted differently than as described, the Depositor, Servicer and Trustee
will reasonably cooperate to amend the provisions of this Section 8.12 in order
to comply with such

                                      116
<PAGE>

amended reporting requirements and such amendment of this Section 8.12. Any such
amendment shall be made in accordance with Section 10.01 without the consent of
the Certificateholders, and may result in a change in the reports filed by the
Trustee on behalf of the Trust under the Exchange Act. Notwithstanding the
foregoing, the Depositor, Servicer and Trustee shall not be obligated to enter
into any amendment pursuant to this Section 8.12 that adversely affects its
obligations and immunities under this Agreement.

          (g) Prior to January 31 of the first year in which the Trustee is able
to do so under applicable law, the Trustee shall file a Form 15D Suspension
Notification with respect to the Trust.

                                   TERMINATION

          SECTION 9.01 Termination upon Liquidation or Purchase of the Mortgage
                       Loans.

          Subject to Section 9.03, the rights, obligations and responsibilities
of the Depositor, the Seller, the Servicer and the Trustee created hereunder
with respect to the Trust Fund shall terminate upon the earlier of (a) the
purchase by the Optional Termination Holder of all Mortgage Loans (and REO
Properties) remaining at the price equal to the sum of (A) 100% of the Aggregate
Collateral Balance plus one month's accrued interest thereon at the applicable
Mortgage Rate, (B) the lesser of (x) the appraised value of any REO Property as
determined by the higher of two appraisals completed by two independent
appraisers selected by the Depositor at the expense of the Depositor and (y) the
Stated Principal Balance of each Mortgage Loan related to any REO Property, in
each case plus accrued and unpaid interest thereon at the applicable Mortgage
Rate and (C) any unreimbursed Servicing Advances and (b) the later of (i) the
maturity or other 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 (ii) the distribution to Certificateholders of all amounts required
to be distributed to them pursuant to this Agreement. In no event shall the
trusts created hereby continue beyond the expiration of 21 years from the death
of the survivor of the descendants of Joseph P. Kennedy, the late Ambassador of
the United States to the Court of St. James's, living on the date hereof. The
right to repurchase all Mortgage Loans and REO Properties pursuant to clause (a)
above shall be conditioned upon the aggregate Stated Principal Balance of the
Mortgage Loans and the appraised value of the REO Properties at the time of any
such repurchase, aggregating less than ten percent of the Aggregate Collateral
Balance as of the Cut-off Date.

          SECTION 9.02 Final Distribution on the Certificates.

          If on any Determination Date, the Trustee determines that there are no
Outstanding Mortgage Loans and no other funds or assets in the Trust Fund other
than the funds in the Collection Accounts and Certificate Account, the Trustee
shall promptly send a final distribution notice to each Certificateholder. If
the Optional Termination Holder above elects to terminate the Trust Fund
pursuant to Section 9.01, at least 20 days prior to the date notice is to be
mailed to the affected Certificateholders such Person shall notify the Servicer
and the Trustee of the date the Depositor intends to terminate the Trust Fund
and of the applicable repurchase price of the Mortgage Loans and REO Properties.

          Notice of any termination of the Trust Fund, specifying the
Distribution Date on which Certificateholders shall surrender their Certificates
for payment of the final distribution and cancellation, shall be given promptly
by the Trustee by letter to Certificateholders mailed not earlier than the 10th
day and not later than the 15th day of the month next preceding the month of
such final distribution. Any such notice shall specify (a) the Distribution Date
upon which final distribution on the Certificates will be made upon presentation
and surrender of Certificates at the office therein designated, (b) the amount
of such final distribution, (c) the location of the office or agency at which
such presentation and surrender must be made, and (d) that the Record Date
otherwise applicable

                                      118
<PAGE>

to such Distribution Date is not applicable, distributions being made only upon
presentation and surrender of the Certificates at the office therein specified.
The Trustee shall give such notice to each Rating Agency at the time such notice
is given to Certificateholders.

          Upon presentation and surrender of the Certificates, the Trustee shall
cause to be distributed to the Certificateholders of each Class, in each case on
the final Distribution Date and in the order set forth in Section 4.02, in the
case of the Certificateholders, in proportion to their respective Percentage
Interests, with respect to Certificateholders of the same Class, an amount equal
to (i) as to each Class of Regular Certificates, the Certificate Balance thereof
plus accrued interest thereon (or on their Notional Amount, if applicable) in
the case of an interest-bearing Certificate and (ii) as to the Residual
Certificates, the amount, if any, which remains on deposit in the Collection
Accounts (other than the amounts retained to meet claims) after application
pursuant to clause (i) above.

          In the event that any affected 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 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 applicable 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 a part of
the Trust Fund. If within one year after the second notice all Certificates
shall not have been surrendered for cancellation, the Class A-R
Certificateholders shall be entitled to all unclaimed funds and other assets of
the Trust Fund which remain subject hereto and the Trustee shall be discharged
from all further liability with respect to the Certificates and this Agreement.

          SECTION 9.03 Additional Termination Requirements.

          (a) In the event that the Optional Termination Holder exercises its
purchase option with respect to the Mortgage Loans as provided in Section 9.01,
at such time as the Mortgage Loans are so purchased, the Trust Fund shall be
terminated in accordance with the following additional requirements, unless the
Trustee has been supplied with an Opinion of Counsel, at the expense of the
Depositor, to the effect that the failure to comply with the requirements of
this Section 9.03 will not (i) result in the imposition of taxes on "prohibited
transactions" on any REMIC as defined in Section 860F of the Code, or (ii) cause
REMIC 1, REMIC 2 or REMIC 3 to fail to qualify as a REMIC at any time that any
Certificates are outstanding:

              (1) Within 90 days prior to the final Distribution Date set forth
                  in the notice given by the Trustee under Section 9.02, the
                  Depositor shall prepare and the Trustee, at the expense of the
                  Depositor, shall adopt a plan of complete liquidation within
                  the meaning of Section 860F(a)(4) of the Code which, as
                  evidenced by an Opinion of Counsel (which opinion shall not be
                  an expense of the Trustee, the Tax Matters Person or the Trust
                  Fund), meets the requirements of a qualified liquidation;

                                      119
<PAGE>

              (2) Within 90 days after the time of adoption of such a plan of
                  complete liquidation, the Trustee shall sell all of the assets
                  of the Trust Fund to the Depositor for cash in accordance with
                  Section 9.01; and

                       On the date specified for final payment of the
                  Certificates, the Trustee shall, after payment of any
                  unreimbursed Advances, Servicing Advances, Servicing Fees or
                  other fee compensation payable to the Servicer pursuant to
                  this Agreement, make final distributions of principal and
                  interest on the Certificates in accordance with Section 4.02
                  and distribute or credit, or cause to be distributed or
                  credited, to the Holders of the Residual Certificates all cash
                  on hand after such final payment (other than the cash retained
                  to meet claims), and the Trust Fund (and any REMIC) shall
                  terminate at that time.

          (b) The Trustee as agent for REMIC 1, REMIC 2 and REMIC 3 hereby
agrees to adopt and sign such a plan of complete liquidation upon the written
request of the Depositor, and the receipt of the Opinion of Counsel referred to
in Section 9.03(a)(1) and to take such other action in connection therewith as
may be reasonably requested by the Depositor.

          (c) By their acceptance of the Certificates, the Holders thereof
hereby authorize the Depositor to prepare and the Trustee to adopt and sign a
plan of complete liquidation.

                            MISCELLANEOUS PROVISIONS

          SECTION 10.01 Amendment.

          This Agreement may be amended from time to time by the Depositor, the
Servicer, the Seller and the Trustee without the consent of any of the
Certificateholders (i) to cure any ambiguity or mistake, (ii) to correct any
defective provision herein or to supplement any provision herein which may be
inconsistent with any other provision herein, (iii) to add to the duties of the
Depositor, the Seller or any Servicer, (iv) to add any other provisions with
respect to matters or questions arising hereunder or (v) to modify, alter,
amend, add to or rescind any of the terms or provisions contained in this
Agreement; provided that any action pursuant to clauses (iv) or (v) above shall
not, as evidenced by an Opinion of Counsel (which Opinion of Counsel shall not
be an expense of the Trustee or the Trust Fund, but shall be at the expense of
the party proposing such amendment), adversely affect in any material respect
the interests of any Certificateholder; provided, however, that no such Opinion
of Counsel shall be required if the Person requesting the amendment obtains a
letter from each Rating Agency stating that the amendment would not result in
the downgrading or withdrawal of the respective ratings then assigned to the
Certificates; it being understood and agreed that any such letter in and of
itself will not represent a determination as to the materiality of any such
amendment and will represent a determination only as to the credit issues
affecting any such rating. The Trustee, the Depositor, the Seller and the
Servicer also may at any time and from time to time amend this Agreement without
the consent of the Certificateholders to modify, eliminate or add to any of its
provisions to such extent as shall be necessary or helpful to (i) maintain the
qualification of REMIC 1, REMIC 2 or REMIC 3 as a REMIC under the Code, (ii)
avoid or minimize the risk of the imposition of any tax on the Trust Fund
pursuant to the Code that would be a claim at any time prior to the final
redemption of the Certificates or (iii) comply with any other requirements of
the Code, provided that the Trustee has been provided an Opinion of Counsel,
which opinion shall be an expense of the party requesting such opinion but in
any case shall not be an expense of the Trustee or the Trust Fund, to the effect
that such action is necessary or helpful to, as applicable, (i) maintain such
qualification, (ii) avoid or minimize the risk of the imposition of such a tax
or (iii) comply with any such requirements of the Code.

          This Agreement may also be amended from time to time by the Depositor,
the Servicer, the Seller and the Trustee with the consent of the Holders of a
Majority in Interest of each Class of Certificates affected thereby for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Agreement or of modifying in any manner the rights of
the Holders of Certificates; provided, however, that no such amendment shall (i)
reduce in any manner the amount of, or delay the timing of, payments required to
be distributed on any Certificate without the consent of the Holder of such
Certificate, (ii) adversely affect in any material respect the interests of the
Holders of any Class of Certificates in a manner other than as described in
clause (i), without the consent of the Holders of Certificates of such Class
evidencing, as to such Class, Percentage Interests aggregating 66%, or (iii)
reduce the aforesaid percentages of Certificates the Holders of which are
required to consent to any such amendment, without the consent of the Holders of
all such Certificates then outstanding.

                                      121
<PAGE>

          Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel, which opinion shall not be an expense of the
Trustee or the Trust Fund, but shall be at the expense of the party preparing
such amendment, to the effect that such amendment will not cause the imposition
of any federal tax on the Trust Fund or the Certificateholders or cause REMIC 1,
REMIC 2 or REMIC 3 to fail to qualify as a REMIC at any time that any
Certificates are outstanding.

          Promptly after the execution of any amendment to this Agreement, the
Trustee shall furnish written notification of the substance or a copy of such
amendment to each Certificateholder if the consent of Certificateholders was
required and each Rating Agency.

          It shall not be necessary for the consent of Certificateholders under
this Section 10.01 to approve the particular form of any proposed amendment, but
it shall be sufficient if such consent shall approve the substance thereof. The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

          Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel (which Opinion shall not be an
expense of the Trustee or the Trust Fund), satisfactory to the Trustee that (i)
such amendment is permitted and is not prohibited by this Agreement and that all
requirements for amending this Agreement have been complied with; and (ii)
either (A) the amendment does not adversely affect in any material respect the
interests of any Certificateholder or (B) the conclusion set forth in the
immediately preceding clause (A) is not required to be reached pursuant to this
Section 10.01.

          SECTION 10.02 Recordation of Agreement; Counterparts.

          This Agreement is subject to recordation in all appropriate public
offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the properties subject to the Mortgages are
situated, and in any other appropriate public recording office or elsewhere,
such recordation to be effected by the Depositor at its expense, but only upon
direction by the Trustee accompanied by an Opinion of Counsel to the effect that
such recordation materially and beneficially affects the interests of the
Certificateholders.

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

          SECTION 10.03 Governing Law.

          Notwithstanding anything to the contrary contained herein, except as
provided in Sections 6.02 and 6.04, this Agreement may not be assigned by the
Servicer without the prior written consent of the Trustee and Depositor;
provided, however, that neither the Depositor nor the Trustee shall consent to

assignment will not cause a reduction or withdrawal of the ratings then assigned
by it to any Class of Certificates.

          SECTION 10.08 Limitation on Rights of Certificateholders.

          The death or incapacity of any Certificateholder shall not operate to
terminate this Agreement or the trust created hereby, 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 created hereby, or otherwise affect the rights,
obligations and liabilities of the parties hereto or any of them.

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

          No Certificateholder shall have any right by virtue or by availing
itself of any provisions of this Agreement to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Agreement,
unless such Holder previously shall have given to the Trustee a written notice
of an Event of Default and of the continuance thereof, as herein provided, and
unless the Holders of Certificates evidencing not less than 25% of the Voting
Rights evidenced by the Certificates shall also have made written request to the
Trustee to institute such action, suit or proceeding in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity as it
may require against the costs, expenses, and liabilities to be incurred therein
or thereby, and the Trustee, for 60 days after its receipt of such notice,
request and offer of indemnity shall have neglected or refused to institute any
such action, suit or proceeding; it being understood and intended, and being
expressly covenanted by each Certificateholder with every other

Certificateholder and the Trustee, that no one or more Holders of Certificates
shall have any right in any manner whatever by virtue or by availing itself or
themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over or preference to any other such Holder or to enforce any
right under this Agreement, except in the manner herein provided and for the
common benefit of all Certificateholders. For the protection and enforcement of
the provisions of this Section 10.08, each and every Certificateholder and the
Trustee shall be entitled to such relief as can be given either at law or in
equity.

          SECTION 10.09 Certificates Nonassessable and Fully Paid.

          It is the intention of the Depositor that Certificateholders shall not
be personally liable for obligations of the Trust Fund, that the interests in
the Trust Fund represented by the Certificates shall be nonassessable for any
reason whatsoever, and that the Certificates, upon due authentication thereof by
the Trustee pursuant to this Agreement, are and shall be deemed fully paid.

satisfactory to the Trustee, to the effect that such transferee is not an

Code, or a person acting on behalf of any such plan or arrangement or using the
assets of any such plan or arrangement to effect such transfer, which
representation letter shall not be an expense of the Trustee or the Trust Fund,
(ii) if the purchaser is an insurance company, a representation that the
purchaser is an insurance company which is purchasing such Certificates with
funds contained in an "insurance company general account" (as such term is
defined in Section V(e) of Prohibited Transaction Class Exemption 95-60 ("PTCE
95-60")) and that the purchase and holding of such Certificates satisfy the
requirements for exemptive relief under Sections I and III of PTCE 95-60 or
(iii) in the case of any such Certificate presented for registration in the name
of an employee benefit plan subject to ERISA, or Section 4975 of the Code (or
comparable provisions of any subsequent enactments), or a trustee of any such
plan or any other person acting on behalf of any such plan or arrangement, or
using such plan's or arrangement's assets, an Opinion of Counsel satisfactory to
the Trustee to the effect that the purchase or holding of such Certificate will
not result in the assets of the Trust Fund being deemed to be "plan assets" and
subject to the prohibited transaction provisions of ERISA and the Code and will
not subject the Trustee or the Servicer to any obligation in addition to those
undertaken in this Agreement, which Opinion of Counsel shall not be an expense
of the Trustee or the Trust Fund. Notwithstanding anything else to the contrary
herein, any purported transfer of a Certificate to or on behalf of an employee
benefit plan subject to ERISA or to the Code without the Opinion of Counsel
satisfactory to the Trustee as described above shall be void and of no effect.]

     [No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state securities laws or is exempt from the
registration requirements under said Act and such laws. In the event that a
transfer is to be made in reliance upon an exemption from the Securities Act and
such laws, in order to assure compliance with the Securities Act and such laws,
the Certificateholder desiring to effect such transfer and such
Certificateholder's prospective transferee shall each certify to the Trustee in
writing the facts surrounding the transfer. In the event that such a transfer is
to be made within three years from the date of the initial issuance of
Certificates pursuant hereto, there shall also be delivered (except in the case
of a transfer pursuant to Rule 144A of the Securities Act) to the Trustee an
Opinion of Counsel that such transfer may be made pursuant to an exemption from
the Securities Act and such state securities laws, which Opinion of Counsel
shall not be obtained at the expense of the Trustee, the Seller, the Servicer or
the Depositor. The Holder hereof desiring to effect such transfer shall, and
does hereby agree to, indemnify the Trustee and the Depositor against any
liability that may result if the transfer is not so exempt or is not made in
accordance with such federal and state laws.]

     Principal in respect of this Certificate is distributable monthly as set
forth herein. Accordingly, the Certificate Balance at any time may be less than
the Certificate Balance as set forth herein. This Certificate is payable solely
from the assets of the Trust and does not evidence an obligation of, or an
interest in, and is not guaranteed by the Depositor, the Seller, the Servicer or
the Trustee referred to below or any of their respective affiliates. This
Certificate and the Mortgage Loans are not guaranteed or insured by any
governmental agency or instrumentality.

     This certifies that [______________________] is the registered owner of the

the Depositor, DLJ Mortgage Capital, Inc. as seller ("DLJMC"), Wilshire Credit
Corporation as servicer ("Wilshire") and JPMorgan Chase Bank as trustee (the

     Any distribution of the proceeds of any remaining assets of the Trust Fund
will be made only upon presentment and surrender of this Class A-R Certificate
at the Corporate Trust Office or the office or agency maintained by the Trustee
in New York, New York.

     No transfer of a Class A-R Certificate shall be made unless the Trustee
shall have received either (i) a representation letter from the transferee of
such Certificate, acceptable to and in form and substance satisfactory to the
Trustee, to the effect that such transferee is not an employee benefit plan
subject to Section 406 of ERISA or Section 4975 of the Code, or a person acting
on behalf of any such plan or arrangement or using the assets of any such plan
or arrangement to effect such transfer, which representation letter shall not be
an expense of the Trustee or the Trust Fund or (ii) in the case of any such
Class A-R Certificate presented for registration in the name of an employee
benefit plan subject to ERISA, or Section 4975 of the Code (or comparable
provisions of any subsequent enactments), or a trustee of any such plan or any
other person acting on behalf of any such plan or arrangement, or using such
plan's or arrangement's assets, an Opinion of Counsel satisfactory to the
Trustee to the effect that the purchase or holding of such Class A-R Certificate
will not result in the assets of the Trust Fund being deemed to be "plan assets"
and subject to the prohibited transaction provisions of ERISA and the Code and
will not subject the Trustee to any obligation in addition to those undertaken
in this Agreement, which Opinion of Counsel shall not be an expense of the
Trustee or the Trust Fund. Notwithstanding anything else to the contrary herein,
any purported transfer of a Class A-R Certificate to or on behalf of an employee
benefit plan subject to ERISA or to the Code without the Opinion of Counsel
satisfactory to the Trustee as described above shall be void and of no effect.

     Each Holder of this Class A-R Certificate will be deemed to have agreed to
be bound by the restrictions of the Agreement, including but not limited to the
restrictions that (i) each person holding or acquiring any Ownership Interest in
this Class A-R Certificate must be a Permitted Transferee, (ii) no Ownership
Interest in this Class A-R Certificate may be transferred without delivery to
the Trustee of (a) a transfer affidavit of the proposed transferee and (b) a
transfer certificate of the transferor, each of such documents to be in the form
described in the Agreement, (iii) each person holding or acquiring any Ownership
Interest in this Class A-R Certificate must agree to require a transfer
affidavit and to deliver a transfer certificate to the Trustee as required
pursuant to the Agreement, (iv) each person holding or acquiring an Ownership
Interest in this Class A-R Certificate must agree not to transfer an Ownership
Interest in this Class A-R Certificate if it has actual knowledge that the
proposed transferee is not a Permitted Transferee and (v) any attempted or
purported transfer of any Ownership Interest in this Class A-R Certificate in
violation of such restrictions will be absolutely null and void and will vest no
rights in the purported transferee.

     Reference is hereby made to the further provisions of this Certificate set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

     This Certificate shall not be entitled to any benefit under the Agreement
or be valid for any purpose unless manually countersigned by an authorized

     This Certificate does not have a pass-through rate and will be entitled to
distributions only to the extent set forth in the Agreement.

     No transfer of a Certificate of this Class shall be made unless such
transfer is made pursuant to an effective registration statement under the Act
and any applicable state securities laws or is exempt from the registration
requirements under said Act and such laws. In the event that a transfer is to be
made in reliance upon an exemption from the Act and such laws, in order to
assure compliance with the Act and such laws, the Certificateholder desiring to
effect such transfer and such Certificateholder's prospective transferee shall
each certify to the Trustee and the Depositor in writing the facts surrounding
the transfer. In the event that such a transfer is not to be made pursuant to
Rule 144A of the Act, there shall be delivered to the Trustee and the Depositor
of an Opinion of Counsel that such transfer may be made pursuant to an exemption

or arrangement to effect such transfer, which representation letter shall not be

provisions of any subsequent enactments), or a trustee of any such plan or any
other person acting on behalf of any such plan or arrangement, or using such

in this Agreement, which Opinion of Counsel shall not be an expense of the
Trustee or the Trust Fund. Notwithstanding anything else to the contrary herein,
any purported transfer of a Class P Certificate to or on behalf of an employee
benefit plan subject to ERISA or to the Code without the Opinion of Counsel
satisfactory to the Trustee as described above shall be void and of no effect.

     This Certificate is one of a duly authorized issue of Certificates
designated as Credit Suisse First Boston Mortgage Securities Corp., Mortgage
Pass-Through Certificates, of the Series specified on the face hereof (herein
collectively called the "Certificates"), and representing a beneficial ownership
interest in the Trust Fund created by the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the funds on deposit in the Certificate Account 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 thereby, and the rights, duties and
immunities of the Trustee.

     Pursuant to the terms of the Agreement, a distribution will be made on the
25th day of each month or, if such 25th day is not a Business Day, the Business
Day immediately following (the "Distribution Date"), commencing on the first
Distribution Date specified on the face hereof, to the Person in whose name this
Certificate is registered at the close of business on the applicable Record Date
in an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount required to be distributed to Holders of Certificates
of the Class to which this Certificate belongs on such Distribution Date
pursuant to the Agreement. [The Record Date applicable to each Distribution Date
is the last Business Day of the month next preceding the month of such
Distribution Date.][The Record Date applicable to each Distribution Date is the
Business Day immediately preceding the related Distribution Date; provided that
if this Certificate is not a Book-Entry Certificate, then the Record Date
applicable to each Distribution Date is the last Business Day of the month next
preceding such Distribution Date.]

     Distributions on this Certificate shall be made by wire transfer of
immediately available funds to the account of the Holder hereof at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing at least five Business Days prior
to the related Record Date and such Certificateholder shall satisfy the
conditions to receive such form of payment set forth in the Agreement, or, if
not, by check mailed by first class mail to the address of such
Certificateholder appearing in the Certificate Register. The final distribution
on each Certificate will be made in like manner, but only upon presentment and
surrender of such Certificate at the Corporate Trust Office or such other
location specified in the notice to Certificateholders of such final
distribution.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Trustee and the rights of the Certificateholders under the Agreement at any time
by the Depositor, the Servicer, the Seller and the Trustee with the consent of
the Holders of Certificates affected by such amendment evidencing the requisite
Percentage Interest, as provided in the Agreement. Any such consent by the
Holder of this Certificate shall be conclusive and binding on such Holder and
upon all future Holders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange therefor 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 in the Certificate
Register of the Trustee upon surrender of this Certificate for registration of
transfer at the Corporate Trust Office or the office or agency maintained by the
Trustee in New York, New York, accompanied by a written instrument of transfer
in form satisfactory to the Trustee and the Certificate Registrar duly executed
by the holder hereof or such holder's attorney duly authorized in writing, and
thereupon one or more new Certificates of the same Class in authorized
denominations and evidencing the same aggregate Percentage Interest in the Trust
Fund will be issued to the designated transferee or transferees.

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

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

     The Depositor, the Servicer, the Seller and the Trustee and any agent of
the Depositor or the Trustee may treat the Person in whose name this Certificate
is registered as the owner hereof for all purposes, and the Seller, the
Depositor, the Trustee, or any such agent shall be affected by any notice to the
contrary.

     On any Distribution Date on which the sum of the aggregate Stated Principal
Balance of the Mortgage Loans and the appraised value of the REO Properties at
the time of repurchase is less than 10% of the sum of the Aggregate Collateral
Balance of the Mortgage Loans, the Optional Termination Holder will have the
option to repurchase, in whole, from the Trust Fund all remaining Mortgage Loans
and REO Properties at a purchase price determined as provided in the Agreement.
In the event that no such optional termination occurs, the obligations and
responsibilities created by the Agreement will terminate upon the later of the
maturity or other liquidation (or any advance with respect thereto) of the last
Mortgage Loan remaining in the Trust Fund and the distribution to
Certificateholders of all amounts required to be distributed pursuant to the
Agreement. In no event, however, will the trust created by the Agreement
continue beyond the expiration of 21 years from

COUNTY OF      )

     The undersigned, being first duly sworn, deposes and says as follows:

     1. The undersigned is an officer of _______________ , the proposed
Transferee of an Ownership Interest in a Class A-R Certificate (the
"Certificate") issued pursuant to the Pooling and Servicing Agreement, (the
"Agreement"), relating to the above-referenced Series, among Credit Suisse First
Boston Mortgage Securities Corp. as depositor, DLJ Mortgage Capital, Inc. as
seller ("DLJMC"), Wilshire Credit Corporation as servicer ("Wilshire") and
JPMorgan Chase Bank as trustee (the "Trustee"). Capitalized terms used, but not
defined herein or in Exhibit 1 hereto, shall have the meanings ascribed to such
terms in the Agreement. The Transferee has authorized the undersigned to make
this affidavit on behalf of the Transferee.

     2. The Transferee is, as of the date hereof, and will be, as of the date of
the Transfer, a Permitted Transferee. The Transferee is acquiring its Ownership
Interest in the Certificate either (i) for its own account or (ii) as nominee,
trustee or agent for another Person and has attached hereto an affidavit from
such Person in substantially the same form as this affidavit. The Transferee has
no knowledge that any such affidavit is false.

     3. The Transferee has been advised of, and understands that (i) a tax will
be imposed on Transfers of the Certificate to Persons that are not Permitted
Transferees; (ii) such tax will be imposed on the transferor, or, if such
Transfer is through an agent (which includes a broker, nominee or middleman) for
a Person that is not a Permitted Transferee, on the agent; and (iii) the Person
otherwise liable for the tax shall be relieved of liability for the tax if the
subsequent Transferee furnished to such Person an affidavit that such subsequent
Transferee is a Permitted Transferee and, at the time of Transfer, such Person
does not have actual knowledge that the affidavit is false.

     4. The Transferee has been advised of, and understands that a tax will be
imposed on a "pass-through entity" holding the Certificate if at any time during
the taxable year of the pass-through entity a Person that is not a Permitted
Transferee is the record holder of an interest in such entity. The Transferee
understands that such tax will not be imposed for any period with respect to
which the record holder furnishes to the pass-through entity an affidavit that
such record holder is a Permitted Transferee and the pass-through entity does
not have actual knowledge that such affidavit is false. (For this purpose, a
"pass-through entity" includes a regulated investment company, a real estate
investment trust or common trust fund, a partnership, trust or estate, and

                                       I-1

<PAGE>

Person.)

     5. The Transferee has reviewed the provisions of Section 5.02(c) of the
Agreement (attached hereto as Exhibit 2 and incorporated herein by reference)
and understands the legal consequences of the acquisition of an Ownership
Interest in the Certificate including, without limitation, The restrictions on
subsequent Transfers and the provisions regarding voiding the Transfer and
mandatory sales. The Transferee expressly agrees to be bound by and to abide by
the provisions of Section 5.02(c) of the Agreement and the restrictions noted on
the face of the Certificate. The Transferee understands and agrees that any
breach of any of the representations included herein shall render the Transfer
to the Transferee contemplated hereby null and void.

     6. The Transferee agrees to require a Transfer Affidavit from any Person to
whom the Transferee attempts to Transfer its Ownership Interest in the
Certificate, and in connection with any Transfer by a Person for whom the
Transferee is acting as nominee, trustee or agent, and the Transferee will not
Transfer its Ownership Interest or cause any Ownership Interest to be
Transferred to any Person that the Transferee knows is not a Permitted
Transferee. In connection with any such Transfer by the Transferee, The
Transferee agrees to deliver to the Trustee a certificate substantially in the
form set forth as EXHIBIT J to the Agreement (a "Transferor Certificate") to the
effect that such Transferee has no actual knowledge that the Person to which the
Transfer is to be made is not a Permitted Transferee.

     7. The Transferee does not have the intention to impede the assessment or
collection of any tax legally required to be paid with respect to the
Certificate.

     8. The Transferee's taxpayer identification number is [_____________].

     9. The Transferee is a United States Person.

     10. The Transferee is aware that the Certificate may be a "noneconomic
residual interest" within the meaning of proposed Treasury regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

     11. The Transferee is (a) not an employee benefit plan that is subject to
ERISA or a plan that is subject to Section 4975 of the Code, and the Transferee
is not acting on behalf of such a plan or (b) an employee benefit plan that is
subject to ERISA or a plan that is subject to Section 4975 of the Code, and the
Transferee is not acting on behalf of such a plan and will provide an Opinion of
Counsel in accordance with the provisions of Agreement.

CERTAIN DEFINITIONS
-------------------

     "Ownership Interest": As to any Residual Certificate, any ownership
interest in such Certificate, including any interest in such Certificate as the
Holder thereof and any other interest therein, whether direct or indirect, legal
or beneficial.

     "Permitted Transferee": Any person other than (i) The United States, any
State or political subdivision thereof, or any agency or instrumentality of any
of the foregoing, (ii) a foreign government, International Organization or any
agency or instrumentality of either of the foregoing, (iii) an organization
(except certain farmers' cooperatives described in section 521 of the Code)
which is exempt from tax imposed by Chapter 1 of the Code (including the tax
imposed by section 511 of the Code on unrelated business taxable income) on any
excess inclusions (as defined in section 860E(c)(1) of the Code) with respect to
any Residual Certificate, (iv) rural electric and telephone cooperatives
described in section 1381(a)(2)(C) of the Code, (v) a Person that is not a
citizen or resident of the United States, a corporation, partnership, or other
entity created or organized in or under the laws of the United States, any State
thereof or the District of Columbia, or an estate whose income from sources
without the United States is includible in gross income for federal income tax
purposes regardless of its connection with the conduct of a trade or business
within the United States or a trust if a court within the United States is able
to exercise primary supervision over the administration of the trust and one or
more United States persons have the authority to control all substantial
decisions of the trust unless such Person has furnished the transferor and the
Trustee with a duly completed Internal Revenue Service Form W-8ECI or successor
form, and (vi) any other Person so designated by the Depositor based upon an

     (ix) The Mortgage Note and the Mortgage are not subject to any right of
rescission, set-off, counterclaim or defense, including, without limitation, the
defense of usury, nor will the operation of any of the terms of the Mortgage

meeting the requirements of the current guidelines of the Federal Insurance
Administration which policy conforms to FNMA and FHLMC requirements, as well as
all additional requirements set forth in this Agreement. Such policy was issued
by an insurer acceptable under FNMA or FHLMC guidelines. The Mortgage obligates
the Mortgagor thereunder to maintain all such insurance at the Mortgagor's cost
and expense, and upon the Mortgagor's failure to do so, authorizes the holder of
the Mortgage to maintain such insurance at the Mortgagor's cost and expense and
to seek reimbursement therefor from the Mortgagor.

     (xvi) The Mortgage creates a first or second lien or a first or second
priority ownership interest in an estate in fee simple in real property securing
the related Mortgage Note.

     (xvii) As of the Cut-off Date, no Mortgage Loan is (a) a non-performing
loan (i.e. a mortgage loan that is more than 90 days delinquent); (b) a
re-performing loan (i.e. a mortgage loan that was more than 90 days delinquent
within the twelve month period preceding the Cut-off Date but is contractually
current); or (c) a sub-performing loan (i.e. a mortgage loan that is at least 30
days delinquent but subject to a payment plan or agreement pursuant to which the
Mortgagor is contractually current).

     (xviii) The Mortgage Note and the related Mortgage are original and genuine
and each is the legal, valid and binding obligation of the maker thereof,
enforceable in all respects in accordance with its terms subject to bankruptcy,
insolvency, moratorium, reorganization and other laws of general application
affecting the rights of creditors and by general equitable principles.

     (xix) No Mortgage Loan that was originated on or after October 1, 2002 and
before March 7, 2003, which is secured by a Mortgaged Property located in the
State of Georgia is a "home loan" as defined in the Georgia Fair Lending Act (HB
1361), as amended.

     (xx) Each Mortgage Loan at the time it was made complied in all material
respects with applicable local, state and federal laws, including, but not
limited to, all applicable predatory and abusive lending laws.
