                              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 ten 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-1 Certificates, (vi) the Class B-2 Certificates,

                                     -------

                  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 the Interest Rate Cap
Account and the Interest Rate Cap Agreement) as a real estate mortgage
investment conduit (a "REMIC") for federal income tax purposes, and such
segregated pool of assets will be designated as "REMIC 1." The Class R-1
Interest will represent the sole class of "residual interests" in REMIC 1 for
purposes of the REMIC Provisions (as defined 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

         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

                                       42

<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 MERS(R) 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 any Servicer to, and each 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

                                       43

<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.

                  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.

                  The Custodian is required under the Custodial Agreement to
execute and deliver on the Closing Date to the Depositor, the Seller, the
Trustee and the Servicers 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, pursuant to the Custodial Agreement,
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
Servicers 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, pursuant to the Custodial Agreement, 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.

                                       44

<PAGE>

                  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 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.

                  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 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

                                       45

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
                               Servicers.

                  (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 IIIA
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.

                  (c) Ocwen, in its capacity as Servicer, hereby makes the
representations and warranties set forth in Schedule IIIB 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 applicable Cut- off Date.

                  (d) Long Beach, in its capacity as Servicer, hereby makes the
representations and warranties set forth in Schedule IIIC 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 applicable Cut- off Date.

                  (e) Each of Wilshire, Long Beach and Ocwen, in their 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.

                  (f) 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 if so specified
therein, as of the Cut-off Date or such other date as may be specified.

                  (g) Upon discovery by any of the parties hereto of a breach of
a representation or warranty made pursuant to Section 2.03(f) 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(f) 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;

                                       46

<PAGE>

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 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(f) 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 sum
of (i) the aggregate of any unreimbursed Advances with respect to

                                       47

<PAGE>

such Deleted Mortgage Loans and (ii) any costs and damages actually incurred and
paid by or on behalf of the Trust in connection with any breach of the
representation and warranty set forth in Schedule III (xx) as the result of a
violation of a predatory or abusive lending law applicable to such Mortgage Loan
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 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

                                       48

<PAGE>

(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 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 Class A-1, Class A-2, Class M-1, Class M-2,
Class B-1, Class B-2, Class P and Class X-1 Certificates shall be designated as
the "regular interests" in REMIC 2. The Class A-R Certificates will represent
beneficial ownership of two residual interests, each of which will constitute
the sole class of residual interests in each of REMIC 1 and REMIC 2. The Trustee
shall not permit the creation of any "interests" (within the meaning of Section
860G of the Code) in REMIC 1 or REMIC 2 other than the Certificates or the
Uncertificated REMIC Regular Interests. The "tax matters person" with respect to
each of REMIC 1 and REMIC 2 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 each Servicer.

                  Each respective 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 such Servicer and delivered
to the Depositor, any affiliate of the Depositor or the Trustee and prepared by
such 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 Regular Certificates and the Class R-2 Interest. The Trustee acknowledges
receipt

                                       49

<PAGE>

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 Regular Certificates and the Class R-2 Interest. The
interests evidenced by the Class R-2 Interest, together with the Regular
Certificates, constitute the entire beneficial ownership interest in REMIC 2.

                  (b) In exchange for the REMIC 1 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-2 Interest) the entire beneficial ownership interest in REMIC 2.

                  (c) 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); and (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) 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

                          ADMINISTRATION AND SERVICING
                                OF MORTGAGE LOANS

                  SECTION 3.01 Servicers to Service Mortgage Loans.

                  For and on behalf of the Certificateholders, each Servicer
shall service and administer the Mortgage Loans in accordance with the terms of
this Agreement and with Accepted Servicing Practices. The obligations of each of
Wilshire, Long Beach and Ocwen hereunder to service and administer the Mortgage
Loans shall be limited to the Wilshire Serviced Loans, the Long Beach Serviced
Loans and the Ocwen Serviced Loans, respectively; and with respect to the duties
and obligations of each Servicer, references herein to "Mortgage Loans" or
"related Mortgage Loans" shall be limited to the Wilshire Serviced Loans (and
the related proceeds thereof and related REO Properties) in the case of
Wilshire, the Long Beach Serviced Loans (and the related proceeds thereof and
related REO Properties) in the case of Long Beach and the Ocwen Serviced Loans
(and the related proceeds thereof and related REO Properties), in the case of
Ocwen, and in no event shall any Servicer have any responsibility or liability
with respect to any of the other Mortgage Loans. Notwithstanding anything in
this Agreement, any Servicing Agreement or any Credit Risk Management Agreement
to the contrary, neither Ocwen nor Wilshire shall have any duty or obligation to
enforce any Credit Risk Management Agreement or to supervise, monitor or oversee
the activities of the Credit Risk Manager under its Credit Risk Management
Agreement with respect to any action taken or not taken by Ocwen or Wilshire, as
applicable, pursuant to a recommendation of the Credit Risk Manager. In
connection with such servicing and administration, each 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 a 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 each Servicer, prepared by each
Servicer and reasonably acceptable to the Trustee, to permit each Servicer to
act on behalf of the Trustee under this Agreement. Each 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. Each
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. Each Servicer
further is hereby authorized and empowered in its own name or in the name of the
Subservicer, when such 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

                                       51

<PAGE>

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 such Servicer. Notwithstanding the
foregoing, subject to Section 3.05(a), the Servicers 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 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 or REMIC
2 to fail to qualify as a REMIC. Without limiting the generality of the
foregoing, each 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 such 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. Each
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 such Servicer to service and administer the
Mortgage Loans to the extent that such 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 such
Servicer.

                  In accordance with the standards of the preceding paragraph,
each 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 each
Servicer shall be required to advance only to the extent that such advances, in
the good faith judgment of such Servicer, will be recoverable by such 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 a 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 a Servicer, and furnish to such Servicer and any Subservicer
such documents as are necessary or appropriate to enable such Servicer or any
Subservicer to carry out their servicing and administrative duties

                                       52

<PAGE>

hereunder, and the Trustee hereby grants to each Servicer a power of attorney to
carry out such duties. The Trustee shall not be liable for the actions of the
Servicers 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 related Servicer, in such capacity, may consent to the refinancing of
the prior senior lien, provided that the following requirements are met:

                  (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.

                  With respect to the Mortgage Loans, the Servicer of each
Mortgage Loan agrees that, with respect to the Mortgagors of such Mortgage
Loans, such Servicer for each Mortgage Loan shall furnish, in accordance with
the Fair Credit Reporting Act and its implementing regulations, accurate and
complete information on its borrower credit files to Equifax, Experian and Trans
Union Credit Information Company on a monthly basis.

                  SECTION 3.02 Subservicing; Enforcement of the Obligations of
                               Subservicers.

                  (a) The Mortgage Loans may be subserviced by a Subservicer on
behalf of the related 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. A 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 such Servicer of
the Subservicer shall not release such Servicer from any of its obligations
hereunder and such Servicer shall remain responsible hereunder for all acts and
omissions of the Subservicer as fully as if such acts and omissions were those
of such Servicer. Each Servicer shall pay all fees and expenses of any
Subservicer engaged by such Servicer from its own funds.

                  Notwithstanding the foregoing, each 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 such
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 a
Servicer of any such Outsourcer shall not release such Servicer from any of its
obligations hereunder and such Servicer shall remain responsible hereunder for
all acts and omissions of such Outsourcer as fully as if such

                                       53

<PAGE>

acts and omissions were those of such Servicer, and such Servicer shall pay all
fees and expenses of the Outsourcer from such Servicer's own funds.

                  (b) At the cost and expense of a Servicer, without any right
of reimbursement from the Depositor, Trustee, the Trust Fund, or the applicable
Collection Account, such 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 such Servicer, at such
Servicer's option, from electing to service the related Mortgage Loans itself.
In the event that a Servicer's responsibilities and duties under this Agreement
are terminated pursuant to Section 7.01, and if requested to do so by the
Trustee, such Servicer shall at its own cost and expense terminate the rights
and responsibilities of its Subservicer as soon as is reasonably possible. Each
Servicer shall pay all fees, expenses or penalties necessary in order to
terminate the rights and responsibilities of its Subservicer from such
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 a Servicer and its Subservicer, a
Servicer and its Outsourcer, or any reference herein to actions taken through
the Subservicer, the Outsourcer, or otherwise, no Servicer shall 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. Each Servicer
shall be entitled to enter into an agreement with its Subservicer and Outsourcer
for indemnification of such 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, a 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 such 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 related
Servicer alone, and the Depositor, the Trustee and the other Servicer 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 any Servicer shall for any reason no
longer be a 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 such Servicer hereunder arising thereafter (except that the
Trustee shall not be (i) liable for losses of such Servicer pursuant to Section
3.09 hereof or any acts

                                       54

<PAGE>

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 such Servicer
hereunder). Any such assumption shall be subject to Section 7.02 hereof.

                  Each Servicer shall, upon request of the Trustee, but at the
expense of such 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
such 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.

                  (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, each 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 a 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, each 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 such 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 such 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 such 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 and provided, further, that any such waiver, modification,
postponement or indulgence granted to a Mortgagor by a Servicer in connection
with

thereof by reason of such arrangements. Each 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.

                                       55

<PAGE>

its servicing of the related First Mortgage Loan shall not be considered
relevant to a determination of whether such Servicer has acted consistently with
the terms and standards of this Agreement, so long as in such Servicer's
determination such action is not materially adverse to the interests of the
Certificateholders. In the event of any such arrangement, the related 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

                  (b) Each 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 2003-4"
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 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 applicable Servicer in
accordance with Section 3.08.

                  Each Servicer shall deposit in the Collection Account within
two Business Days of receipt and retain therein, the following collections
remitted by Subservicers or payments received by such Servicer and payments made
by such 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 such 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 such
         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;

                                       56

<PAGE>

                  (vii) any amounts required to be deposited by such 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 such Servicer into such Collection Account. In addition, notwithstanding the
provisions of this Section 3.05, each 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 a
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. Each Servicer shall 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 each 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 a 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(b). In no event shall the Trustee incur liability for withdrawals from the
Certificate Account at the direction of a Servicer.

                  (d) Each institution at which a Collection Account or the
Certificate Account is maintained shall either hold such funds on deposit
uninvested or shall invest the funds therein as directed in writing by the
related Servicer (in the case of a Collection Account) or the Trustee (in the

                                       57
<PAGE>

case of the Certificate 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, 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 related 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 related Servicer in the related 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. 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.

                  (e) Each 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 each 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.

                  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 applicable 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 2003-4"
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 [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 related 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 a Servicer, or
by a letter agreement in the form of Exhibit P-2 hereto, in the case of an
account held by a depository other than a Servicer. A copy of such certification
shall be furnished to the Depositor and Trustee.

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

                                       58
<PAGE>

                  (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.

                  Each 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). Each 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 applicable 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 related 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 such Servicer for any Servicing Advances
         made by such 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;

                  (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 such 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.

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

                  (a) Each 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 such
Servicer.

                  (b) Each Servicer shall inspect the Mortgaged Properties as
often as deemed necessary by such Servicer in such 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 delinquent, each Servicer
shall conduct subsequent inspections in accordance with Accepted Servicing
Practices or as may be required by the primary mortgage guaranty insurer. Each
Servicer shall keep a written or electronic report of each such inspection.

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

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

                  (ii) to reimburse such 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 and 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 such Servicer);

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

                  (iv) to reimburse such Servicer for (A) unreimbursed Servicing
         Advances, such 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 and 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, (B) for
         unpaid Servicing Fees

                                       60
<PAGE>

         as provided in Section 3.11 and unreimbursed Servicing Advances and
         Advances as provided in Section 3.11(a)(iv)(A) hereof and (C) in the
         case of Ocwen, for (i) unpaid Servicing Fees not otherwise collected
         from Liquidation Proceeds and (ii) deboarding fees pursuant to Section
         3.11(a)(iv)(A) or Section 6.04(b);

                  (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 such 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;

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

                  Each 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
related Servicer shall deliver to the Trustee a certificate of a Servicing
Officer indicating the amount of any previous Advance determined by such
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 applicable Servicer for
         deposit to the Collection Account any amount deposited in the
         Certificate Account and not required to be deposited therein; and

                                       61
<PAGE>

                  (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.

                  Each 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 a Servicer under any such policy relating to a Mortgage Loan (for
the avoidance of doubt, remaining after application of any such amounts to any
related First Mortgage Loan) shall be deposited in the related 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 related 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 such Servicer's
funds, without reimbursement therefor. Upon request of the Trustee, a 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, each 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 a 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 such 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 a 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, each 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 such Servicer, will be recoverable.

                  A 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, each Servicer shall comply with
the following conditions in connection with any such release of Insurance
Proceeds:

                                       62
<PAGE>

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

                  (ii) such 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 mechanics' and materialmen's liens;
         and

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

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

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

                  Each 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
related 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 such 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 or, if consistent with Accepted
Servicing Practices, the Servicer believes the collections and other recoveries
in respect of such Mortgage Loans could reasonably be expected to be maximized
if the Mortgage Loan were not accelerated.

                  If a Servicer reasonably believes it is unable under
applicable law to enforce such "due-on-sale" clause or, if any of the other
conditions set forth in the last sentence of the preceding paragraph apply, such
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 such Servicer is unable under applicable law to
require that the original Mortgagor remain liable under the Mortgage Note and
such 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, a Servicer shall
not be deemed to be in default under this Section by reason of any transfer or
assumption which such 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.

                                       63
<PAGE>

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

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

                  (a) (i) Each 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, each 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 related Servicer shall take
such action as (i) such 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) such Servicer shall
determine consistently with Accepted Servicing Practices to be in the best
interest of the Trustee and Certificateholders, provided, that actions taken by
a Servicer in connection with its servicing of the related First Mortgage Loan
shall not be considered relevant to a determination of whether such Servicer has
met the standard set forth in this clause (iii), so long as so long as in such
Servicer's determination such action is not materially adverse to the interests
of the Certificateholders and (iv)

                                       64
<PAGE>

is consistent with the requirements of the insurer under any Required Insurance
Policy; provided, however, that such 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
related Collection Account). The related 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 related Servicer shall obtain a broker's price
opinion with respect to the related Mortgaged Property and shall use all
reasonable efforts to obtain a total indebtedness balance (including, but not
limited to, unpaid principal, interest, escrows, taxes and expenses) for any
related senior lien. The cost of obtaining any such broker's price opinion shall
be reimbursable to the related Servicer as a Servicing Advance pursuant to
Section 3.08(iii) or (iv). After obtaining the related broker's price opinion,
the related Servicer will determine whether any Significant Net Recovery is
possible through foreclosure proceedings or other liquidation of the related
Mortgaged Property. If the related 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 related 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 may, at its discretion, charge off such delinquent Mortgage Loan in
accordance with subsections (a)(iii) and (a)(iv) below. As to any Ocwen Serviced
Loan:

                           (A) prior to obtaining the broker's price opinion
                  described above and thereafter except as described in clause
                  (B) below, Ocwen shall have absolutely no obligation to
                  perform loss mitigation or default management services (other
                  than its standard collection activities) with respect to any
                  such Mortgage Loan, provided, however, that Ocwen shall be
                  entitled to receive its Servicing Fee with respect to such
                  Mortgage Loan through the 120th day of delinquency; and

                           (B) if Ocwen determines that (x) a Significant Net
                  Recovery is possible through foreclosure proceedings or other
                  liquidation of the related Mortgaged Property and (y) the
                  potential Net Recoveries are anticipated to be an amount,
                  determined by Ocwen 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, then Ocwen shall Special Service
                  the related Mortgage Loan and shall receive as servicing
                  compensation (i) $100 per month from the date on which Ocwen
                  begins to Special Service such Mortgage Loan through
                  foreclosure or liquidation and (ii) $135 per month for the
                  period during which Ocwen is Special Servicing the related REO
                  Property, provided that, if Ocwen acts as Special Servicer
                  with respect to a Mortgage Loan pursuant to this clause (B),

                                       65
<PAGE>

                  Ocwen shall receive such compensation in lieu of its Servicing
                  Fee pursuant to clause (A) above. As to any Ocwen Serviced
                  Loan for which Ocwen is to receive the compensation described
                  in the previous sentence in lieu of its Servicing Fee, Ocwen
                  shall report such information to the Trustee together with the
                  information reported to the Trustee on each Servicer Data
                  Remittance Date pursuant to Section 4.06 hereof.

                  (iii) If the related 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 related 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
related Servicer will discontinue making Advances, the related 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 related Servicer will follow the
procedures described in paragraph (a)(iv) below. If the related 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 related
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, such Servicer may continue
to make Advances or Servicing Advances on the related Mortgage Loan that has
become 180 days delinquent and, in the case of Ocwen or Wilshire, as applicable,
will notify the Credit Risk Manager of that decision.

                  (iv) (A) With respect to any Ocwen Serviced Loan or Long Beach
                  Serviced Loan that becomes a Charged Off Loan, Ocwen or Long
                  Beach, as applicable, shall notify Wilshire of its decision to
                  charge off such Mortgage Loan and the servicing of such Ocwen
                  Serviced Loan or Long Beach Serviced Loan will be transferred
                  to Wilshire, such transfer to be initiated by Ocwen or Long
                  Beach, as applicable, on the 15th day of the month (or if the
                  15th of the month is not a Business Day, the next Business
                  Day) following the month in which such Ocwen Serviced Loan or
                  Long Beach Serviced Loan becomes a Charged Off Loan and may be
                  serviced, at Wilshire's discretion, using Wilshire Special
                  Servicing as provided in paragraph (iv)(B) below. Immediately
                  upon transfer of any Ocwen Serviced Loan or Long Beach
                  Serviced Loan to Wilshire, Ocwen or Long Beach, as applicable,
                  shall be reimbursed for all unreimbursed Advances and
                  Servicing Advances (including any trailing expenses incurred
                  prior to but invoiced after the date servicing is transferred
                  to Wilshire, so long as Ocwen or Long Beach, as applicable,
                  notifies the Trustee of such trailing expenses within 60 days
                  of the date of such transfer) and unpaid Servicing Fees
                  relating to such transferred Mortgage Loan out of funds on
                  deposit in the Collection Account. The related Servicer shall
                  provide an Officer's Certificate to the Trustee no later than
                  the related Servicer Remittance Date evidencing the amount to
                  be reimbursed pursuant to the previous sentence with respect
                  to any Mortgage Loans

                                       66
<PAGE>

                  transferred by such Servicer to Wilshire. With respect to any
                  Ocwen Serviced Loan transferred to Wilshire pursuant to this
                  clause (iv)(A) prior to such Mortgage Loan being serviced by
                  Ocwen for a period of one year, Ocwen shall receive $25 as a
                  deboarding fee. Ocwen or Long Beach shall notify the Trustee
                  of any Ocwen Serviced Loan or Long Beach Serviced Loan, as
                  applicable, that is transferred to Wilshire. Ocwen or Long
                  Beach, as applicable, shall provide servicing information on
                  such transferred Mortgage Loans as reasonably requested by
                  Wilshire including, but not limited to, an electronic data
                  tape containing the fields set forth in Exhibit T hereto, and
                  an electronic file or hard copy containing collection
                  comments, outstanding advance balances, payment histories, and
                  hardcopies of any imaged files. Ocwen or Long Beach, as
                  applicable, shall be responsible for any other reasonable
                  actions required by Accepted Servicing Practices relating to
                  the transfer of servicing and the charging off of such
                  Mortgage Loans. All costs of such transfer of the electronic
                  data tape and files relating to Ocwen Serviced Loans shall be
                  paid by Ocwen. All costs of such transfer of the electronic
                  data tape and files relating to Long Beach Serviced Loans
                  shall be reimbursable to Long Beach as a Servicing Advance
                  immediately upon transfer of such Long Beach Serviced Loans to
                  Wilshire. Neither Ocwen nor Long Beach shall be responsible
                  for Wilshire's boarding costs of such transferred Mortgage
                  Loans. Wilshire shall not be responsible for the reimbursement
                  of any Advance or Servicing Advance on a transferred Mortgage
                  Loan.

                           (B) Any (x) Wilshire Serviced Loan that becomes a
                  Charged Off Loan and (y) any Ocwen Serviced Loan or Long Beach
                  Serviced Loan that becomes a Charged Off Loan and is
                  transferred to Wilshire pursuant to paragraph (iv)(A) above
                  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

                                       67
<PAGE>

(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 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, and if the modification would adversely affect or
materially increase the obligations of Ocwen or Long Beach, with the consent of
Ocwen or Long Beach, as applicable, 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 related 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 such Servicer. Upon completion of the inspection, the related
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 related Servicer shall not proceed with foreclosure or
acceptance of a deed in lieu of foreclosure if the estimated costs of the

                                       68
<PAGE>

environmental clean up, as estimated in the environmental inspection report,
together with the Servicing Advances made by such 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 related Servicer may, in
its reasonable judgment and in accordance with Accepted Servicing Practices,
choose to proceed with foreclosure or acceptance of a deed in lieu of
foreclosure and such 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 such Servicer, such Servicer shall be entitled to be reimbursed from
amounts in the related Collection Account pursuant to Section 3.08 hereof. In
the event the related Servicer does not proceed with foreclosure or acceptance
of a deed in lieu of foreclosure pursuant to the first sentence of this
paragraph, such 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, such 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 related 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 related 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 related Servicer, either itself or through an
agent selected by such 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
related 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 related 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
such 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 related 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

                                       69
<PAGE>

for filing. Notwithstanding the previous sentence, with respect to any Ocwen
Serviced Loan or Long Beach Serviced Loan that becomes a Charged Off Loan and is
transferred to Wilshire pursuant to Section 3.11(a)(iv)(A) above, neither Ocwen
nor Long Beach shall file a Form 1099C or other tax report relating to the
forgiveness of debt of the related Mortgagor.

                  To the extent consistent with Accepted Servicing Practices,
the related 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 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 a 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, each 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 such 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 related 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 applicable 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 applicable 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 related 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 related 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

                                       70
<PAGE>

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 a Servicer to foreclose on a defaulted
Mortgage Loan shall be subject to a determination by such 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 such 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 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.

                  No Servicer shall 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 applicable 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. With respect to
each Servicer, the foregoing percentage limitations will apply only to the
Mortgage Loans serviced by such Servicer.

                  (e) The proceeds from any liquidation of a Mortgage Loan, as
well as any income from an REO Property, if applicable, will be applied in the
following order of priority: first, to reimburse the related Servicer for any
related unreimbursed Servicing Advances and Servicing Fees; second, to reimburse
such Servicer for any unreimbursed Advances; third, to reimburse the related
Collection Account for any Nonrecoverable Advances (or portions thereof) that
were previously withdrawn by such 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

                                       71
<PAGE>

of principal of the Mortgage Loan. Excess proceeds, if any, from the liquidation
of a Liquidated Mortgage Loan will be retained by the related 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 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 a Servicer of a notification that payment in full will be escrowed in a
manner customary for such purposes, such 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
related Servicer, and the Trustee shall within three Business Days of such
Servicer's direction execute and deliver to such 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 such
Servicer, together with the Mortgage Note with written evidence of cancellation
thereon. Each 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 related Servicer. Subject to
the further limitations set forth below, the related 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 such Servicer no longer
exists, unless the Mortgage Loan is liquidated and the proceeds thereof are
deposited in the related Collection Account, in which case such 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.

                                       72
<PAGE>

                  If a Servicer at any time seeks to initiate a foreclosure
proceeding in respect of any Mortgaged Property as authorized by this Agreement,
such Servicer shall, if applicable, deliver or cause to be delivered to the
Trustee, for signature, as appropriate, any court pleadings, requests for
trustee's sale or other documents (which, if acceptable by the related court,
may be copies) 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.

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

                  Notwithstanding any other provisions of this Agreement, each
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 related 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 such Servicer or which otherwise are collected by such
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, a 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 related 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. Each 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 (other
than the lien of a related First Mortgage Loan), 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 such
Servicer shall be entitled to set off against and deduct from any such funds any
amounts that are properly due and payable to such Servicer under this Agreement.

                  SECTION 3.14 Servicing Fee.

                  As compensation for its services hereunder, each 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 such 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 related Servicer or as otherwise provided in Section 3.08.

                  Additional servicing compensation in the form of Ancillary
Income shall be retained by the related Servicer. Each 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

                  SECTION 3.15 Access to Certain Documentation.

                  Each 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
such Servicer. Nothing in this Section shall limit the obligation of any
Servicer to observe any applicable law prohibiting disclosure of information
regarding the Mortgagors and the failure of such 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 any Servicer
to collect, create, collate or otherwise generate any information that it does
not generate in its usual course of business.

                  SECTION 3.16 Annual Statement as to Compliance.

                  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), each Servicer shall deliver to the Depositor, the Rating Agencies
and the 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 such Servicer under this Agreement has been made
under such officer's supervision, and (ii) to the best of such officer's
knowledge, based on such review, such Servicer has fulfilled all its obligations
under this Agreement throughout such year, or, if there has been a default in
the fulfillment of any such obligation, specifying each such default known to
such officer and the nature and status thereof and the action being taken by
such Servicer to cure such default.

                  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), each Servicer at its expense shall cause a nationally or
regionally recognized firm of independent public accountants (who may also
render other services to such 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 such Servicer is servicing, which may include the related

                                       74
<PAGE>

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, each Servicer
shall disclose to such firm all significant deficiencies relating to such
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 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 related
Servicer's expense, provided such statement is delivered by such Servicer to the
Trustee.

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

                  Each 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 related
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 a 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 related 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 the Depositor with 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

                                       75
<PAGE>

Management Agreement and the Credit Risk Manager shall look solely to the
related 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; provided, however, that in no event shall Long
Beach be obligated or required to provide any such loan level information or any
other data to the Credit Risk Manager under this Agreement. 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 Servicers, 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 a 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 Agreements. 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 Agreements in the performance of its
duties thereunder and hereunder.

                  SECTION 3.21 Advance Facility.

                  (a) Ocwen and Wilshire are each hereby authorized to enter
into a financing or other facility (any such arrangement, an "Advance Facility")
under which (1) Ocwen or Wilshire, as applicable, assigns or pledges to another
Person (an "Advancing Person") such Servicer's 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 Ocwen or Wilshire, as applicable, pursuant to this Agreement. No consent
of the Trustee, Certificateholders or any other party is required before Ocwen
or Wilshire, as applicable, 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 Ocwen or Wilshire, as
applicable, 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 such Servicer's behalf, Ocwen or Wilshire, as applicable, 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 Ocwen or
Wilshire enters into an Advance Facility, and for so long as an Advancing Person

                                       76
<PAGE>

remains entitled to receive reimbursement for any Advances or Servicing Advances
outstanding and previously unreimbursed pursuant to this Agreement, then Ocwen
or Wilshire, as applicable, 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 Ocwen or Wilshire, as applicable, shall be required to include
amounts collected that would otherwise be retained by Ocwen or Wilshire, as
applicable, to reimburse it for previously unreimbursed Advances ("Advance
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. Ocwen or Wilshire, as applicable, 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 Ocwen or Wilshire enters into an Advance Facility and
makes the election set forth in Section 3.21(a), Ocwen or Wilshire, as
applicable, 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 Ocwen or Wilshire, as applicable,
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 Ocwen or Wilshire, as applicable, would be permitted to
reimburse itself in accordance with Section 3.08(ii), (iii) and (iv) hereof,
assuming Ocwen or Wilshire, as applicable, 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 applicable Servicer's
report of the amount of Advance Reimbursement Amounts and Servicing Advance
Reimbursement Amounts that were included in the remittance from Ocwen or
Wilshire, as applicable, to the Trustee pursuant to Section 3.08(viii). Ocwen or
Wilshire, as applicable, shall maintain and provide to any successor

                                       77
<PAGE>

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
Ocwen or Wilshire, as applicable, 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
Ocwen or 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 Ocwen or Wilshire, as applicable, to
provide to the related Advancing Person or Advance Facility Trustee loan-by-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.
Ocwen or Wilshire, as applicable, shall remain entitled to be reimbursed by the
Advancing Person or Advance Facility Trustee for all Advances and Servicing
Advances funded by Ocwen or Wilshire, as applicable, to the extent the related
rights to be reimbursed therefor have not been assigned or pledged to an
Advancing Person.

                  (f) If Ocwen or Wilshire enters into an Advance Facility,
Ocwen or Wilshire, as applicable, 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 Ocwen or
Wilshire, as applicable, 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 SERVICERS

                  SECTION 4.01 Advances by the Servicers.

                  Each Servicer shall deposit in a Collection Account an amount
equal to 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; provided however, that with respect to
any Balloon Loan that is delinquent on its maturity date, the related 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).
Each 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 such Servicer, been completely liquidated;
provided however, that such obligation with respect to any related Mortgage Loan
shall cease if such Servicer determines, in its reasonable opinion, that
Advances with respect to such Mortgage Loan are Nonrecoverable Advances;
provided that the related 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 related Servicer determines that such
Advances with respect to such Mortgage Loan are Nonrecoverable Advances. In the
event that such Servicer determines that any such Advances are Nonrecoverable
Advances, such 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 related
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 related 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 related 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
related 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.

                  SECTION 4.02 Priorities of Distribution.

                  (a) On each Distribution Date, prior to making distributions
to the holders of the Certificates, the Trustee first, shall pay itself the
Trustee's Fee for such Distribution Date, and second, shall pay the Credit Risk
Manager the Credit Risk Manager Fee.

                  (b) With respect to the Available Funds, on each Distribution
Date, the Trustee shall withdraw such Available Funds from the Certificate
Account and based on the information provided to it by the Servicers, apply such
funds to distributions on the Certificates in the following order and priority
and, in each case, to the extent of such Available Funds remaining:

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

                  A.       to the Senior Certificates, pro rata, Current
                           Interest and any Carryforward Interest, as
                           applicable, for each such Class and such Distribution
                           Date;

                  B.       to the Class M-1 Certificates, Current Interest and
                           any Carryforward Interest for such Class and such

                  C.       to the Class M-2 Certificates, Current Interest and

                           Distribution Date;

                  D.       to the Class B-1 Certificates, Current Interest and

                           Distribution Date;

                  E.       to the Class B-2 Certificates, Current Interest and
                           any Carryforward Interest for such Class and such
                           Distribution Date; and

                  F.       for application in the same manner as the Monthly

                  (ii) On each Distribution Date (a) prior to the Stepdown Date
         or (b) with respect to which a Trigger Event has occurred, the Trustee
         shall distribute the Principal Payment Amount for such date in the
         following order of priority:

                           case until the Class Principal Balance thereof has
                           been reduced to zero;

                  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
Uncertificated Accrued Interest payable to the REMIC 1 Regular Interests LT-AA
and LT-ZZ up to an aggregate amount equal to the excess of (a) the REMIC 1
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 1 Regular Interests LT-AA and LT-ZZ up to an
aggregate amount equal to the REMIC 1 Principal Loss Allocation Amount, 98% and
2%, respectively; third, to the Uncertificated Principal Balances of REMIC 1
Regular Interest LT-AA, REMIC 1 Regular Interest LT-B2 and REMIC 1 Regular
Interest LT-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated Principal
Balance of REMIC 1 Regular Interest LT-B2 has been reduced to zero; fourth, to

of REMIC 1 Regular Interest LT-AA, REMIC 1 Regular Interest LT-B1 and REMIC 1
Regular Interest LT-ZZ, 98%, 1% and 1%, respectively, until the Uncertificated

fifth, to the Uncertificated Principal Balances of REMIC 1 Regular Interest
LT-AA, REMIC 1 Regular Interest LT-M2 and REMIC 1 Regular Interest LT-ZZ, 98%,

                  (a) Not later than each Distribution Date, the Trustee shall

                  Assistance in using the website can be obtained by calling the
Trustee's customer service desk at 877-722-1095. Parties that are unable to use
the website are entitled to have a paper copy mailed to them via first class
mail by written notice to the Trustee at its Corporate Trust Office. The
Trustee's responsibility for disbursing the above information to the
Certificateholders is limited to the availability, timeliness and accuracy of
the information derived from the Servicers. The foregoing information shall be
reported to the Trustee each month on or before the Servicer Data Remittance
Date.

                  (b) Within a reasonable period of time after the end of each
calendar year, the Trustee shall cause to be furnished to each Person who at any
time during the calendar year was a Certificateholder, a statement containing
the information set forth in, items (i)(c), (i)(d), (i)(g), (i)(j), (i)(k),
(ii)(c), (ii)(d), (ii)(g), (ii)(i), (v)(d), (v)(e) and (v)(s) of Exhibit V

such Person was a Certificateholder. Such obligation of the Trustee shall be
deemed to have been satisfied to the extent that substantially comparable

Code as from time to time in effect.

                  SECTION 4.07 Distributions on the REMIC 1 Regular Interests.

                  (a) Distributions on the REMIC 1 Regular Interests.

following order of priority, the following amounts to be distributed by REMIC 1
to REMIC 2 on account of the REMIC 1 Regular Interests or withdrawn from the
Distribution Account and distributed to the holders of the Class A-R
Certificates (in respect of the Class R-1 Interest), as the case may be:

                  (i) first, to the extent of the sum of Available Funds for
         such Distribution Date, to Holders of REMIC 1 Regular Interests LT-AA,
         LT-A1, LT-A2, LT-M1, LT-M2, LT-B1, LT-B2, LT-ZZ, LT-P and LT-R, pro

         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 1 Regular Interest
         LT-ZZ shall be reduced when the REMIC 1 Overcollateralization Amount is
         less than the REMIC 1 Overcollateralization

                           (a) to the Holders of REMIC 1 Regular Interest LT-R,
         an amount equal to the amount of principal distributed to the holder of
         the Corresponding Certificate on such Distribution Date pursuant to
         Section 4.02; and

                           (b) to the Holders of REMIC 1 Regular Interest LT-P,
         an amount equal to the sum of (i) the amount of principal distributed
         to the holder of the Corresponding Certificate on such Distribution
         Date pursuant to Section 4.02(b)(ii)A. and (ii) the amount distributed
         to the holder of the Corresponding Certificate on such Distribution
         Date pursuant to Section 4.02(b)(v); and

                  (iii) third, to the Holders of REMIC 1 Regular Interests, in

                           (b) with respect to the Holders of REMIC 1 Regular
         Interest LT-A1, LT-A2, LT-M1, LT-M2, LT-B1 and LT-B2, 1.00% of such
         remainder, in the same proportion as principal payments are allocated
         to the Corresponding Certificates, until the Uncertificated Principal
         Balances of such REMIC 1 Regular Interests are reduced to zero;

                           (c) to the Holders of REMIC 1 Regular Interest LT-ZZ,
         1.00% of such remainder, until the Uncertificated Principal Balance of

                  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 related 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 related 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 related Servicer may waive a
Prepayment Penalty in connection with a short sale or short payoff on a
defaulted Mortgage Loan. If the related Servicer has waived all or a portion of
a Prepayment Penalty relating to a Principal Prepayment, other than as provided
above, the related 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 related Servicer shall not have any
obligation to pay the amount of any uncollected Prepayment Penalty under this
Section 4.09 if such Servicer did not have a copy of the related Mortgage Note,
such 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 related 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. Notwithstanding any provision in this Agreement to the contrary, in the
event the Prepayment Penalty payable under the terms of the Mortgage Note is
different from the amount of the Prepayment Penalty set forth in the Mortgage
Loan Schedule or other information provided to the related Servicer, such
Servicer shall rely conclusively on the Prepayment Penalty as set forth under
the terms of the Mortgage Note. To the extent the Prepayment Penalty payable
under the terms of the Mortgage Note is less than the amount of the Prepayment
Penalty set forth in the Mortgage Loan Schedule or other information provided to
the related Servicer, such Servicer shall not have any liability or obligation
with respect to such difference, and in addition shall not have any liability or
obligation to pay the amount of any uncollected Prepayment Penalty if the
failure to collect such amount is the direct result of inaccurate or incomplete
information on the Mortgage Loan Schedule.

                  SECTION 4.10 Servicers to Cooperate.

                  Each 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 serviced by such Servicer 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 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 Part 3(a) of the Schedule to the ISDA Master Agreement.

                  (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, Class B-1 and Class
                  B-2 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 F. 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, to the extent the
                  Overcollateralization Amount for such Distribution Date would
                  be less than or equal to zero after giving effect to such
                  Realized Losses.

                  (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

                                       87

<PAGE>

treat amounts paid by the Interest Rate Cap Account as payments made from
outside the REMIC's 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.

                  (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 on or after the Stepdown Date (so long as a Trigger Event is not in
effect) shall the amount on deposit in the Interest Rate Cap Account exceed
$1,500,000. On of after the Stepdown Date (so long as a Trigger Event is not in
effect) the Trustee shall distribute any amount on deposit in the Interest Rate
Cap Account in excess of $1,500,000 (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.

                                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, 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

                                       89

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.

                  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

                                       90

<PAGE>

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 Servicers 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 Servicers 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 Servicers 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 transferee's (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 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

                                       92

<PAGE>

         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 Servicers, 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, 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

                                       93

<PAGE>

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 Seller, the Servicers, 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 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 Servicers, the Trustee and any agent of the Servicers 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 Servicers, the Trustee or any agent of the Servicers or the Trustee shall be
affected by any notice to the contrary.

                               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 Servicers 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.

                               Sellers and the Servicers.

                  The Depositor, the Seller and each 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 each 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 a Servicer may be merged or
consolidated into another Person in accordance with the following paragraph.

                  Any Person into which the Depositor, the Seller or a Servicer
may be merged or consolidated, or any Person resulting from any merger or
consolidation to which the Depositor, the Seller or a Servicer shall be a party,
or any person succeeding to the business of the Depositor, the Seller or a
Servicer, shall be the successor of the Depositor, the Seller or a 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 a 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 a 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 Servicers and Others.

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

                                       96

of obligations and duties hereunder. The Depositor, the Seller, each Servicer
and any director, officer, employee or agent of the Depositor, the Seller or a
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, each Servicer and any director, officer,
employee or agent of the Depositor, the Seller, the Trustee, or the related
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 any 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 any 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 each Servicer shall be entitled to be reimbursed
therefor out of the Collection Account. Each Servicer's right to indemnity or
reimbursement pursuant to this Section 6.03 shall survive the resignation or
termination of such Servicer as set forth herein.

                  SECTION 6.04 Limitation on Resignation of a Servicer.

                  (a) Subject to Section 6.04(b) below, a 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 a 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 such 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 or Ocwen 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; and provided further that if Ocwen resigns as Servicer
pursuant to this Section 6.04(b), Ocwen shall receive $25 as a deboarding fee
for any Mortgage Loan for which Ocwen was the Servicer for less than one year.

                  SECTION 7.01 Events of Default.

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

                  (i) any failure by a 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
         such Servicer by the Trustee or the Depositor, or to such 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 a Servicer duly to observe or perform in
         any material respect any other of the covenants or agreements on the
         part of such 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 such Servicer by the Trustee or
         the Depositor, or to such 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), (c) or (d), 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 related 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 related Servicer by the Trustee for the benefit
         of the Certificateholders or by the Depositor; or

                  (iv) failure by a 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 a Servicer and such decree or order shall
         have remained in force undischarged or unstayed for a period of 60
         consecutive days; or

<PAGE>

                  (vi) a 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 such Servicer or of or relating to all or substantially
         all of its property; or

                  (vii) any failure of a 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) a 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 a
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 such Servicer (with a copy to each Rating Agency),
terminate all of the rights and obligations of such Servicer under this
Agreement and in and to the related Mortgage Loans and the proceeds thereof,
other than its rights as a Certificateholder hereunder (other than the rights to
reimbursement for Advances and Servicing Advances previously made pursuant to
this Agreement, the right to accrued and unpaid Servicing Fees and the rights
under Section 6.03 with respect to events occurring prior to such termination).
If an Event of Default results from the failure of a Servicer to make an
Advance, the Trustee shall prior to the Distribution Date occurring in the
succeeding calendar month, by notice in writing to such Servicer and the
Depositor (with a copy to each Rating Agency), terminate all of the rights and
obligations of such 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 related Servicer, terminate all of the rights and obligations of such
Servicer under this Agreement (other than rights to reimbursement for Advances
and Servicing Advances previously made, as provided in Section 3.08, the right
to accrued and unpaid Servicing Fees and the rights under Section 6.03 with
respect to events occurring prior to such termination) and

                                       99

<PAGE>

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.

                  Upon receipt by a Servicer of such written notice of
termination, all authority and power of such Servicer under this Agreement,
whether with respect to the related Mortgage Loans or otherwise, shall pass to
and be vested in the Trustee or its nominee. Upon written request from the
Trustee, such 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 related 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 related Mortgage Loans and related
documents, at such Servicer's sole expense. Each Servicer shall cooperate with
the Trustee and such successor in effecting the termination of such 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 such Servicer to the Collection Account or
Escrow Account or thereafter received with respect to the related Mortgage
Loans. The Trustee shall thereupon make any Advance. The Trustee is hereby
authorized and empowered to execute and deliver, on behalf of such 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 a Servicer receives a notice of
termination pursuant to Section 7.01 of this Agreement or the resignation of
such Servicer pursuant to Section 6.04, the Trustee shall, subject to and to the
extent provided herein, be the successor to such 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 such 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 such 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 such Servicer. Notwithstanding the
foregoing, if the Trustee has become the successor to a 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 such Servicer hereunder in the assumption of all or any part of the
responsibilities, duties or liabilities of such Servicer hereunder. Any
successor to a 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

                                      100

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 such Servicer (other than liabilities of such Servicer under
Section 6.03 hereof incurred prior to termination of such Servicer under Section
7.01 hereunder), with like effect as if originally named as a party to this
Agreement; provided that each Rating Agency 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 such 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 such 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 any
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 a 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 such 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 a
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.

                  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.

                  (i) the Trustee may request and conclusively rely upon and

         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

         ascertain or confirm the genuineness of any signature of any such party
         or parties;

                  (ii) the Trustee may consult with counsel, financial advisers

         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,

         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

         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

         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 a 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, any 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 Servicers, to the extent such indemnity related to the failure of the
related 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 related 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

                                       105

<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, each 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 each Servicer and the
Seller and one copy to the successor trustee.

                                       106

<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 each 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 each 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, each
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.

                                       107

                  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, each 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 each
Servicer and the Trustee may consider necessary or desirable. If a 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 a 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

                                       108

<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 each 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 and REMIC 2
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 and
REMIC 2 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-through entity in

                                       109

<PAGE>

which a Non-Permitted Transferee is the record holder of an interest (the
reasonable cost 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 and REMIC 2
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 or REMIC 2; (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, each 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 and REMIC 2
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 or REMIC 2.

                  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

                                       110

<PAGE>

otherwise provided for herein, such tax shall be paid by (i) the Trustee, if any
such other tax arises out of or results from a breach by the Trustee of any of
its obligations under this Agreement, (ii) the related Servicer or the Seller,
in the case of any such minimum tax, if such tax arises out of or results from a
breach by such 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 a Servicer nor the Trustee shall enter into any
arrangement by which any of REMIC 1 or REMIC 2 will receive a fee or other
compensation for services nor permit any of REMIC 1 or REMIC 2 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 each 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, each
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.

                                       111

<PAGE>

                  (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 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), each
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. Each Servicer agrees to indemnify and hold harmless the Depositor,
the Trustee and each Person, if any, who "controls" 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 such 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 such Servicer is unavailable or insufficient to hold harmless such
Persons, then such 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 such Servicer on the other. Each
Servicer acknowledges that the Depositor and the Trustee are relying on such
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

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, Servicers and Trustee will reasonably cooperate to
amend the provisions of this Section 8.12 in order to comply with such 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, Servicers 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 Servicers 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 Loan 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 Loan 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 Servicers 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

                                       114

<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 or REMIC 2 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;

                           (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 each
                                    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 and REMIC 2 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

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

                            MISCELLANEOUS PROVISIONS

                  SECTION 10.01 Amendment.

                  This Agreement may be amended from time to time by the
Depositor, each 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
Servicers 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 or REMIC 2 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 Servicers, 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.

                  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 or REMIC 2 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.

                  THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND

                  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

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

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

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

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.

         evidencing a percentage interest in the distributions allocable to the
         Certificates of the above-referenced Class with respect to a Trust Fund
         consisting primarily of a pool of conventional mortgage loans (the
         "Mortgage Loans") secured by fixed rate, first and second lien
         residential mortgage loans.

       Credit Suisse First Boston Mortgage Securities Corp., as Depositor

         Principal in respect of this Certificate is distributable monthly as
set forth herein. Accordingly, the Certificate Balance of this Class P
Certificate at any time may be less than the Initial Certificate Balance set
forth on the face hereof, as described herein. This Class P Certificate does not
evidence an obligation of, or an interest in, and is not guaranteed by the
Depositor, the Servicers or the Trustee referred to below or any of their
respective affiliates.

         This certifies that _________________ is the registered owner of the
Percentage Interest evidenced by this Class P Certificate (obtained by dividing
the Denomination of this Class P Certificate by the Initial Class Principal
Balance) in certain distributions with respect to a Trust consisting primarily
of the Mortgage Loans deposited by Credit Suisse First Boston Mortgage
Securities Corp. (the "Depositor"). The Trust was created pursuant to a Pooling
and Servicing Agreement dated as of July 1, 2003 (the "Agreement") among the
Depositor, DLJ Mortgage Capital Inc., as seller ("DLJMC"), Wilshire Credit
Corporation as a servicer ("Wilshire"), Long Beach Mortgage Company as a
servicer ("Long Beach"), Ocwen Federal Bank FSB as a servicer ("Ocwen") and
JPMorgan Chase Bank, as trustee (the "Trustee"). To the extent not defined
herein, the capitalized terms used herein have the meanings assigned in the
Agreement. This Class P Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which

                                       E-2

<PAGE>

Agreement the Holder of this Class P Certificate by virtue of the acceptance
hereof assents and by which such Holder is bound.

         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
from the Act, which Opinion of Counsel shall not be obtained at the expense of
the Trustee, the Seller, the Servicers or the Depositor; or there shall be
delivered to the Trustee and the Depositor a transferor certificate by the
transferor and an investment letter shall be executed by the transferee. The
Holder hereof desiring to effect such transfer shall, and does hereby agree to,
indemnify the Trustee and the 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.

         No transfer of a Class P 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 P 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 P 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 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.

         Reference is hereby made to the further provisions of this Class P
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.

          Home Equity Mortgage Pass-Through Certificates, Series 2003-4
                                 Class [_______]

         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.

                                       F-1

         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 Servicers, 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 Servicers, 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

                           ) ss.:
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 a servicer ("Wilshire"), Long
Beach Mortgage Company as a servicer ("Long Beach"), Ocwen Federal Bank FSB as a
servicer ("Ocwen") 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,

                                       I-1

<PAGE>

a real estate investment trust or common trust fund, a partnership, trust or
estate, and certain cooperatives and, except as may be provided in Treasury
Regulations, persons holding interests in pass-through entities as a nominee for
another 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

Corporation, a majority of its board of directors is not selected by such
government unit.

         "Person": Any individual, corporation, partnership, joint venture,
association, limited liability company, joint-stock company, trust,

subdivision thereof.

         "Transfer": Any direct or indirect transfer or sale of any Ownership
Interest in a Residual Certificate.

cities in which payments are to be made or otherwise) it is not possible for
simultaneous payments to be made on any date on which both parties are required
to make payments hereunder, either party may at its option and in its sole
discretion notify the other party that payments on that date are to be made in
escrow. In this case deposit of the payment due earlier on that date shall be
made by 2:00 p.m. (local time at the place for the earlier payment) on that date
with an escrow agent selected by the notifying party, accompanied by irrevocable
payment instructions (i) to release the deposited payment to the intended
recipient upon receipt by the escrow agent of the required deposit of the

of any suit, action or proceeding relating to this Agreement or any Credit

attorney of the other party or any Credit Support Provider has represented,
expressly or otherwise, that such other party would not, in the event of such a
suit action or proceeding, seek to enforce the foregoing waiver and (ii)

         Pooling and Servicing Agreement as a third-party beneficiary, Party A

         instituting against, Party B any bankruptcy, reorganization,
         arrangement, insolvency, moratorium or liquidation proceedings or other
         proceedings under U.S. Federal or state bankruptcy or similar laws (of
         any other jurisdiction) until at least one year and one day after the
         payment in full of all of the Certificates issued under the Pooling and
         Servicing Agreement; and, further acknowledges that Party B's
         obligations hereunder shall be solely the corporate obligations of
         Party B and Party A shall have no recourse, in the absence of willful
         misconduct or fraud, to any of the directors, officers, employees,
         shareholders or affiliates of Party B with respect to any claims,
         losses, damages, liabilities, indemnities or other obligations in
         connection with any transactions contemplated hereby and further, that
         recourse in respect of any obligations of Party B hereunder will be
         limited to the Pooling and Servicing Agreement Collateral (as defined
         above) as applied in accordance with the terms of the Pooling and
         Servicing Agreement and, on exhaustion thereof, all claims against
         Party B arising from this Agreement or contemplated hereby shall be
         extinguished.

(L)      TAX EVENT. In Section 5(b)(ii)(y) of this Agreement the words ", or
         there is a substantial likelihood that it will," shall be deleted.

(M)      AMENDMENT; CONSENT. Section 9(b) of this Agreement is amended by adding
         the following at the end of such Section:

         No amendment, modification or waiver in respect of this Agreement will
         be effective unless the Rating Agency Condition is satisfied.

(N)      ADDITIONAL TRANSACTIONS OR AMENDMENT TO CURRENT TRANSACTION ABSENT
         CONSENT. No Transaction between Party A and Party B (other than the
         Transactions relating to the Relevant Certificates originally entered
         into in connection with the execution of this Agreement) shall be
         entered into, nor shall any amendment, modification or waiver in
         respect of any such Transaction or the Confirmation thereof be entered
         into, unless the Rating Agency Condition is satisfied.

(O)      SEVERABILITY. If any term, provision, covenant, or condition of this
         Agreement, or the application thereof to any party or circumstance,
         shall be held to be invalid or unenforceable (in whole or in part) for
         any reason, the remaining terms, provisions, covenants, and conditions
         hereof shall continue in full force and effect as if this Agreement had
         been executed with the invalid or unenforceable portion eliminated, so
         long as this Agreement as so modified continues to express, without
         material change, the original intentions of the parties as to the
         subject matter of this Agreement and the deletion of such portion of
         this Agreement will not substantially impair the respective benefits or
         expectations of the parties.

         The parties shall endeavor to engage in good faith negotiations to
         replace any invalid or unenforceable term, provision, covenant or
         condition with a valid or enforceable term, provision, covenant or
         condition, the economic effect of which comes as close as possible to
         that of the invalid or unenforceable term, provision, covenant or
         condition.

(P)      TRANSFER. Section 7 is hereby deleted in its entirety and replaced by
         the following:

         "Subject to Section 6(b)(ii) of the Agreement, and except as expressly
         provided in this Agreement, neither this Agreement, any interest or
         obligation in or under this Agreement, nor any Transaction may be
         transferred by either party without the prior written consent of the
         other party and, in the case of a transfer by Party A, the Rating
         Agency Condition being satisfied (other than pursuant to a
         consolidation or amalgamation with, or merger into, or transfer of all
         or substantially all of such party's assets to, or reorganization,
         incorporation, reincorporation, or reconstitution into or as, another
         entity).

(Q)      DOWNGRADE. In the event that Party A's short-term unsecured and
         unsubordinated debt rating is withdrawn or reduced below "A-1," by S&P
         or its short-term unsecured and unsubordinated debt rating is withdrawn
         or reduced below "P-1" by Moody's (and together with S&P, the "Swap
         Rating Agencies", and such rating thresholds, "Approved Rating
         Thresholds"), within 30 days after such rating withdrawal or downgrade
         (unless, within 30 days after such withdrawal or downgrade, each such
         Swap Rating Agency has reconfirmed the rating of the Notes in effect
         immediately prior to such withdrawal or downgrade), Party A, at its own
         expense, shall (i) seek another entity to replace Party A as party to
         this Agreement that meets or exceeds the Approved Rating

                                      AA-15

<PAGE>

         Thresholds on terms substantially similar to this Agreement, (ii)
         obtain a guaranty of, or a contingent agreement of another person with
         the Approved Rating Thresholds, to honor, Party A's obligations under
         this Agreement, (iii) post collateral which will be sufficient to
         restore the immediately prior ratings of the Certificates that were
         rated when issued or (iv) establish any other arrangement satisfactory
         to the applicable Swap Rating Agency which will be sufficient to
         restore the immediately prior ratings of the Certificates.

(R)      LIMITATION ON EVENTS OF DEFAULT.  Notwithstanding the terms of Sections
         5 and 6 of this Agreement, if at any time and so long as Party B has
         satisfied in full all its payment obligations under Section 2(a)(i) of
         this Agreement and has at the time no future payment obligations,
         whether absolute or contingent, under such Section, then unless Party
         A is required pursuant to appropriate proceedings to return to Party B
         or otherwise returns to Party B upon demand of Party B any portion of
         any such payment, (a) the occurrence of an event described in Section
         5(a) of this Agreement with respect to Party B shall not constitute an
         Event of Default or Potential Event of Default with respect to Party B
         as Defaulting Party and (b) Party A shall be entitled to designate an
         Early Termination Date pursuant to Section 6 of this Agreement only as
         a result of the occurrence of a Termination Event set forth in either
         Section 5(b)(i) or 5(b)(ii) of this Agreement with respect to Party A
         as the Affected Party.

(S)      ADDITIONAL DEFINITIONAL PROVISIONS.

         (i) As used in this Agreement, the following terms shall have the
         meanings set forth below, unless the context clearly requires
         otherwise:

                  "Rating Agency Condition" means, with respect to any
                  particular proposed act or omission to act hereunder that the
                  party acting or failing to act having consulted with any of
                  the Rating Agencies then providing a rating of the Relevant
                  Certificates and having received from the Rating Agencies, a
                  written confirmation that the proposed action or inaction
                  would not cause a downgrading or withdrawal of the
                  then-current rating of the Relevant Certificates.

                  "Moody's" means Moody's Investors Services, Inc., or any

                                   SCHEDULE IV

          REPRESENTATIONS AND WARRANTIES RELATING TO THE MORTGAGE LOANS

         DLJMC, in its capacity as Seller, hereby makes the representations and
warranties set forth in this Schedule IV to the Depositor and the Trustee, as of
the Closing Date, or the date specified herein, with respect to the Mortgage
Loans identified on Schedule I hereto.

         (i) The Seller or its affiliate is the sole owner of record and holder
of the Mortgage Loan and the indebtedness evidenced by the Mortgage Note.
Immediately prior to the transfer and assignment to the Depositor on the Closing
Date, the Mortgage Loan, including the Mortgage Note and the Mortgage, were not
subject to an assignment or pledge, and the Seller had good and marketable title
to and was the sole owner thereof and had full right to transfer and sell the
Mortgage Loan to the Depositor free and clear of any encumbrance, equity, lien,
pledge, charge, claim or security interest and has the full right and authority
subject to no interest or participation of, or agreement with, any other party,
to sell and assign the Mortgage Loan and following the sale of the Mortgage
Loan, the Depositor will own such Mortgage Loan free and clear of any
encumbrance, equity, participation interest, lien, pledge, charge, claim or
security interest.

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

         (iii) The terms of the Mortgage Note and the Mortgage have not been
impaired, waived, altered or modified in any respect, except by written
instruments which have been recorded to the extent any such recordation is
required by law, or, necessary to protect the interest of the Depositor. No
instrument of waiver, alteration or modification has been executed, and no
Mortgagor has been released, in whole or in part, from the terms thereof except
in connection with an assumption agreement and which assumption agreement is
part of the Mortgage File and the terms of which are reflected in the Mortgage
Loan Schedule; the substance of any such waiver, alteration or modification has
been approved by the issuer of any related Primary Insurance Policy and title
insurance policy, to the extent required by the related policies.

         (iv) The Mortgage Loan complies with all the terms, conditions and
requirements of the originator's underwriting standards in effect at the time of
origination of such Mortgage Loan.

         (v) The information set forth in the Mortgage Loan Schedule, attached
to the Agreement as Schedule I, is complete, true and correct in all material
respects as of the Cut-off Date.

         (vi) With respect to any first lien Mortgage Loan, the related Mortgage
is a valid, subsisting, enforceable and perfected first lien on the Mortgaged
Property and, with respect to any second lien Mortgage Loan, the related
Mortgage is a valid, subsisting, enforceable and perfected second lien on the
Mortgaged Property, and all buildings on the Mortgaged Property and all
installations and mechanical, electrical, plumbing, heating and air conditioning
systems affixed to such buildings, and all additions, alterations and
replacements made at any time with respect to the foregoing securing the
Mortgage Note's original principal balance. The Mortgage and the Mortgage Note
do not contain any evidence of any security interest or other interest or right
thereto. Such lien

                                      IV-1

<PAGE>

is free and clear of all adverse claims, liens and encumbrances having priority
over the first or second lien, as applicable, of the Mortgage subject only to
(1) with respect to any Second Mortgage Loan, the related First Mortgage Loan,
(2) the lien of non-delinquent current real property taxes and assessments not
yet due and payable, (3) covenants, conditions and restrictions, rights of way,
easements and other matters of the public record as of the date of recording
which are acceptable to mortgage lending institutions generally and either (A)
which are referred to or otherwise considered in the appraisal made for the
originator of the Mortgage Loan, or (B) which do not adversely affect the
appraised value of the Mortgaged Property as set forth in such appraisal, and
(4) other matters to which like properties are commonly subject which do not
materially interfere with the benefits of the security intended to be provided
by the Mortgage or the use, enjoyment, value or marketability of the related
Mortgaged Property. Any security agreement, chattel mortgage or equivalent
document related to and delivered in connection with the Mortgage Loan
establishes and creates (1) with respect to any First Mortgage Loan, a valid,
subsisting, enforceable and perfected first lien and first priority security
interest and (2) with respect to any second lien Mortgage Loan, a valid,
subsisting, enforceable and perfected second lien and second priority security
interest, in each case, on the property described therein, and the Seller has
the full right to sell and assign the same to the Depositor.

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

         (viii) All taxes, governmental assessments, insurance premiums, water,
sewer and municipal charges, leasehold payments or ground rents which previously
became due and owing have been paid, or escrow funds have been established in an
amount sufficient to pay for every such escrowed item which remains unpaid and
which has been assessed but is not yet due and payable.

         (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
Note or the Mortgage, or the exercise of any right thereunder, render the
Mortgage Note or Mortgage unenforceable, in whole or in part, or subject to any
right of rescission, set-off, counterclaim or defense, including the defense of
usury, and no such right of rescission, set-off, counterclaim or defense has
been asserted with respect thereto.

         (x) The Mortgaged Property is not subject to any material damage by
waste, fire, earthquake, windstorm, flood or other casualty. At origination of
the Mortgage Loan there was, and there currently is, no proceeding pending for
the total or partial condemnation of the Mortgaged Property.

         (xi) All improvements subject to the Mortgage which were considered in
determining the appraised value of the Mortgaged Property lie wholly within the
boundaries and building restriction lines of the Mortgaged Property (and wholly
within the project with respect to a condominium unit) and no improvements on
adjoining properties encroach upon the Mortgaged Property except those which are
insured against by a title insurance policy and all improvements on the property
comply with all applicable zoning and subdivision laws and ordinances.

         (xii) Seller has delivered or caused to be delivered to the Trustee or
the Custodian on behalf of the Trustee the original Mortgage bearing evidence
that such instruments have been

                                      IV-2

<PAGE>

recorded in the appropriate jurisdiction where the Mortgaged Property is located
as determined by the Seller (or, in lieu of the original of the Mortgage or the
assignment thereof, a duplicate or conformed copy of the Mortgage or the
instrument of assignment, if any, together with a certificate of receipt from
the Seller or the settlement agent who handled the closing of the Mortgage Loan,
certifying that such copy or copies represent true and correct copy(ies) of the
original(s) and that such original(s) have been or are currently submitted to be
recorded in the appropriate governmental recording office of the jurisdiction
where the Mortgaged Property is located) or a certification or receipt of the
recording authority evidencing the same.

         (xiii) The Mortgage File contains each of the documents specified in
Section 2.01(b) of the Agreement.

         (xiv) As of the Closing Date, each Mortgage Loan shall be serviced in
all material respects in accordance with the terms of the Agreement.

         (xv) All buildings or other customarily insured improvements upon the
Mortgaged Property are insured by an insurer acceptable under the FNMA Guides,
against loss by fire, hazards of extended coverage and such other hazards as are
provided for in the FNMA Guides or by FHLMC, as well as all additional
requirements set forth in this Agreement. All such standard hazard policies are
in full force and effect and on the date of origination contained a standard
mortgagee clause naming the Seller and its successors in interest and assigns as
loss payee and such clause is still in effect and all premiums due thereon have
been paid. If at the time of origination, the Mortgage Loan was required to have
flood insurance coverage in accordance with the Flood Disaster Protection Act of
1973, as amended, such Mortgage Loan is covered by a flood insurance policy
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) With respect to each Mortgage Loan that has a Prepayment Penalty
feature, each such Prepayment Penalty is enforceable and, at the time such
Mortgage Loan was originated, each Prepayment Penalty complied with applicable
federal, state and local law, subject to federal preemption where applicable.

         (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.

amended

material respects with applicable local, state and federal laws, including, but

<PAGE>

                              REVOLVING CREDIT NOTE

$7,000,000.00                                         White Plains, New York
                                                      July 31, 2003

         INTEGRAMED AMERICA, INC., a Delaware corporation (the "Borrower"), for
value received, hereby promises to pay to the order of FLEET NATIONAL BANK (the
"Bank") on the Termination Date, as such term is defined in the Loan Agreement
dated as of September 28, 2001, between the Borrower and the Bank, as amended
from time to time (as so amended the "Agreement"; terms defined in the Agreement
shall have their defined meanings when used in this Note), at the office of the
Bank specified in Section 10.1 of the Agreement, in lawful money of the United
States of America and in immediately available funds the principal amount of
SEVEN MILLION and 00/100 DOLLARS ($7,000,000.00) or, if less than such principal
amount, the aggregate unpaid principal amount of all Loans made by the Bank to
the Borrower pursuant to Section 2.1(a) of the Agreement. The Borrower further
promises to pay interest in like money on the unpaid principal balance of this
Note from time to time outstanding at an annual rate as selected by the Borrower
pursuant to the terms of Section 2.2 of the Agreement. Interest shall be
computed on the basis of a 360-day year for actual days elapsed and shall be
payable as provided in the Agreement. All Loans made by the Bank pursuant to
subsection 2.1(a) of the Agreement and all payments of the principal thereon may
be endorsed by the holder of this Note on the schedule annexed hereto, to which
the holder may add additional pages. The aggregate net unpaid amount of Loans
set forth in such schedule shall be presumed to be the principal balance hereof.
After the stated or any accelerated maturity hereof, this Note shall bear
interest at an increased rate as set forth in the Agreement, payable on demand,
but in no event in excess of the maximum rate of interest permitted under
applicable law.

         This Note is the Revolving Credit Note referred to in the Agreement,
and is entitled to the benefits thereof and may be prepaid, and is required to
be prepaid, in whole or in part (subject to the indemnity provided in the
Agreement) as provided therein. Upon the occurrence of any one or more of the
Events of Default specified in the Agreement, all amounts then remaining unpaid
on this Note may be declared to be immediately due and payable as provided in
the Agreement. This Note is secured by the collateral described in each Security
Agreement.

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

         This Note shall replace and supersede the Revolving Credit Note made by
the Borrower to the order of the Bank dated as of September 28, 2001 (the "Prior
Note"); provided, however, that the execution and delivery of this Note shall
not in any circumstance be deemed to have terminated, extinguished or discharged
the Borrower's indebtedness under such Prior Note, all of which indebtedness
shall continue under and be governed by this Note and the documents, instruments
and agreements executed pursuant hereto or in connection herewith. This Note is
a replacement, consolidation, amendment and restatement of the Prior Note and IS
NOT A NOVATION. The Borrower shall also pay and this Note shall also evidence
any and all unpaid interest on all Revolving Credit Loans made by the Bank to

                                    TERM NOTE

$5,750,000.00                                            White Plains, New York
                                                         July 31, 2003

         INTEGRAMED AMERICA, INC., a Delaware corporation (the "Borrower"), for
value received, hereby promises to pay to the order of FLEET NATIONAL BANK (the
"Bank") at its office specified in Section 10.1 of the Loan Agreement dated as
of September 28, 2001 between the Borrower and the Bank, as amended from time to
time (as so amended the "Agreement"; terms defined in the Agreement shall have
their defined meanings when used in this Note) in lawful money of the United
States and in immediately available funds, the principal sum of Five Million
Seven Hundred Fifty Thousand and 00/100 Dollars ($5,750,000), payable in twelve
(12) consecutive quarterly principal installments as follows: the first eleven
(11) principal installments shall each in an amount equal to Two Hundred Eighty
Seven Thousand Five Hundred Dollars and 00/100 ($287,500.00) and shall be
payable on the last day of each December, March, June and September commencing
September 30, 2003 and the twelfth and final principal installment shall be in
an amount equal to the then remaining unpaid principal balance and shall be due
and payable, together with all accrued and unpaid interest, on June 30, 2006. In
addition to such principal payments, the Borrower further promises to pay
interest at said office in like money on the unpaid principal balance of this
Note from time to time outstanding (computed on the basis of a 360 day year for
actual days elapsed) at an annual rate as selected by the Borrower pursuant to
the terms of Article 2 of the Agreement. Interest shall be payable as provided
in the Agreement. Whenever the entire unpaid principal amount of this Note
becomes due and payable (whether at the stated maturity hereof, by acceleration
or otherwise) interest hereon shall thereafter be payable on demand at a rate as
set forth in the Agreement, but in no event in excess of the maximum rate of
interest permitted under any applicable law.

         This Note is the Term Note referred to in the Agreement, and is
entitled to the benefits and subject to the terms thereof and may be prepaid in
whole or in part (subject to the indemnity provided in the Agreement) as
provided therein. This Note is secured by the Collateral described in each
Security Agreement.

         Upon the occurrence of any one or more of the Events of Default
specified in the Agreement, all amount then remaining unpaid under the Note may
be declared immediately due and payable as provided in the Agreement.

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

         This Note shall replace and supersede the Term Note made by the
Borrower to the order of the Bank dated as of September 11, 1998 (the "Prior
Note"); provided, however, that the execution and delivery of this Note shall
not in any circumstance be deemed to have terminated, extinguished or discharged
the Borrower's indebtedness under such Prior Note, all of which indebtedness
shall continue under and be governed by this Note and the documents, instruments
and agreements executed pursuant hereto or in connection herewith. This Note is
a replacement, increase, consolidation, amendment and restatement of the Prior
Note and IS NOT A NOVATION. The Borrower shall also pay and this Note shall also
evidence any and all unpaid interest on the Term Loan made by the Bank to the
Borrower pursuant to Prior Note, and at the interest rate specified therein, for
which this Note has been issued as replacement therefor.
