                  This is a Pooling and Servicing Agreement, dated as of April
1, 2000, among WMC SECURED ASSETS CORP. (together with its permitted successors
and assigns, the "Company"), WMC MORTGAGE CORP., as master servicer (together
with its permitted successors and assigns, the "Master Servicer") and BANK ONE,
NATIONAL ASSOCIATION, as trustee (together with its permitted successors and
assigns, the "Trustee").

                             PRELIMINARY STATEMENT:

         The Company intends to sell Mortgage 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 (as defined herein) created hereunder. The Trust Fund will
consist primarily of the Mortgage Loans, the Certificate Account, the
Distribution Account and the Pre-Funding Account (each, as defined herein).

         As provided herein, the REMIC Administrator will make an election to
treat the segregated pool of assets described in the definition of REMIC I (as
defined herein), 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 I." The Uncertificated REMIC I Regular Interests (as
defined herein) will evidence the "regular interests" in REMIC I and the Class
R-I Certificates will evidence the sole class of "residual interests" in REMIC I
for purposes of the REMIC Provisions (as defined herein).

         The following table irrevocably sets forth the designation, the
Uncertificated REMIC I 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
Uncertificated REMIC I Regular Interests (as defined herein). None of the
Uncertificated REMIC I Regular Interests will be certificated.

"regular interests" in REMIC III, and the Class R-III Certificates will evidence
the sole class of "residual interests" therein within the meaning of the REMIC
Provisions.

         The following table irrevocably sets forth the designation,
Pass-Through Rate, Initial Certificate Principal Balance, and solely for
purposes of satisfying Treasury regulation section 1.860G-1(a)(4)(iii), the
"latest possible maturity date" for each Class of Certificates representing

                           (ii) the original Mortgage with evidence of recording
                  thereon, or, if the original Mortgage has not yet been
                  returned from the public recording office, a copy of the
                  original Mortgage certified by the Seller, Seller's agent or
                  the public recording office in which such original Mortgage
                  has been submitted for recording;

                           (iii) an Assignment in blank;

                            (iv) originals of any intervening assignments of the
                  Mortgage, with evidence of recording thereon, or, if the
                  original of any such intervening assignment has not yet been
                  returned from the public recording office, a copy of such
                  original intervening assignment certified by the Seller,
                  Seller's agent or the public recording office in which such
                  original intervening assignment has been submitted for
                  recording;

                           (v) the original policy of title insurance (or a
                  commitment for title insurance, if the policy is being held by
                  the title insurance company pending recordation of the
                  Mortgage or has otherwise not yet been received by the title
                  company); and

                           (vi) a true and correct copy of each assumption,
                  modification, consolidation or substitution agreement, if any,
                  relating to the Mortgage Loan.

                  Promptly upon receipt of the recording information for the
Mortgage Loans after the Closing Date (or after the date of transfer of any
Qualified Substitute Mortgage Loan or Subsequent Mortgage Loan), the Seller, at
its own expense (or if the Seller shall have been replaced as Master Servicer,
at the expense of the successor Master Servicer unless the successor Master
Servicer is the Trustee in its capacity as such pursuant to Section 7.02), shall
complete or cause to be completed each original Assignment referred to in clause
(iii) above in the following form: "Bank One, National Association, as Trustee
under the applicable agreement" and submit each Assignment for recording in the
appropriate public recording office for real property records, except in states
where, in the opinion of counsel acceptable to the Trustee, the Rating Agencies
and the Master Servicer, such recording is not required to protect the Trustee's
interest in such Mortgage Loan, against the claim of any subsequent transferee
or any successor to or creditor of the Seller or the originator of such Mortgage
Loan, and the Trustee shall retain a photocopy of each such Assignment. If any
Assignment is lost or returned unrecorded to the Trustee because of any defect
therein, the Seller shall prepare a substitute Assignment or cure such defect,
as the case may be, and the Seller shall cause such substitute Assignment to be
recorded in accordance with this paragraph. Notwithstanding the foregoing,
however, for administrative convenience and facilitation of servicing and to
reduce closing costs, the Assignments shall not be required to be completed and
submitted for recording with respect to any Mortgage Loan if the Trustee and
each Rating Agency has received an opinion of counsel, satisfactory in form and
substance to the Trustee and each Rating Agency, to the effect that the
recordation of such Assignments in any specific jurisdiction is not necessary to
protect the Trustee's interest in the related Mortgage Note; provided further,
however, notwithstanding the delivery of any opinion of counsel, each Assignment
shall be submitted for recording by the Seller (or the successor Master
Servicer) in the manner and within the time frame described above, at no expense
to the Trust Fund or Trustee, upon the earliest to occur of: (i) reasonable
direction by Holders of Certificates entitled to at least 25% of the Voting
Rights stating that failure to record is likely to have a material adverse
effect on the interests of the Certificateholders, (ii) a Servicer Termination
Event, (iii) a bankruptcy, insolvency or foreclosure relating to the Seller,
(iv) a servicing transfer as described in Section 7.02 hereof, (v) if the Seller
is not the Master Servicer and with respect to any one Assignment, a bankruptcy,
insolvency or foreclosure relating to the Mortgagor under the related Mortgage
and (vi) any Mortgage Loan that is 90 days or more Delinquent. Notwithstanding
the foregoing, if the Seller (or the successor Master Servicer) is unable to pay
the cost of recording the Assignments, such expense will be paid by the Trustee
and the Trustee shall be reimbursed for such expenses by the Trust Fund.

                  In instances where an original Mortgage or any original
intervening Assignment was not, in accordance with clause (iii) or (iv) above,
delivered by the Seller to the Trustee on or prior to the Closing Date (or the
date of transfer of any Qualified Substitute Mortgage Loan or Subsequent

                                       43

of such documents to the Trustee promptly upon receipt thereof.

                  The Trustee hereby acknowledges its acceptance of all right,
title and interest to the Mortgage Loans and other property, now existing and
hereafter created, conveyed to the Trust Fund pursuant to this Section 2.01.

                  (c) It is intended that the conveyances by the Company to the
Trustee of the Mortgage Loans as provided for in this Section 2.01 and the
Uncertified REMIC I Regular Interests provided for in Section 2.06 and the
Uncertificated REMIC II Regular Interests provided for in Section 2.07 be
construed as a sale by the Company to the Trustee of the Mortgage Loans, the
Uncertificated REMIC I Regular Interests and the Uncertificated REMIC II Regular
Interests for the benefit of the Certificateholders. Further, it is not intended
that any such conveyance be deemed to be a pledge of the Mortgage Loans, the
Uncertificated REMIC I Regular Interests and the Uncertificated REMIC II Regular
Interests by the Company to the Trustee to secure a debt or other obligation of
the Company. However, in the event that the Mortgage Loans, the Uncertificated
REMIC I Regular Interests and the Uncertificated REMIC II Regular Interests are
held to be property of the Company, or if for any reason this Agreement is held
or deemed to create a security interest in the Mortgage Loans, the
Uncertificated REMIC I Regular Interests and the Uncertificated REMIC II Regular
Interests, then it is intended that (a) this Agreement shall also be deemed to
be a security agreement within the meaning of Articles 8 and 9 of the New York
Uniform Commercial Code and the Uniform Commercial Code of any other applicable
jurisdiction; (b) the conveyances provided for in this Section 2.01 shall be
deemed to be (1) a grant by the Company to the Trustee of a security interest in
all of the Company's right (including the power to convey title thereto), title
and interest, whether now owned or hereafter acquired, in and to (A) the
Mortgage Loans, including the related Mortgage Note, the Mortgage, any insurance
policies and all other documents in the related Mortgage File, (B) all amounts
payable pursuant to the Mortgage Loans in accordance with the terms thereof, (C)
the Uncertificated REMIC I Regular Interests, (D) the Uncertificated REMIC II
Regular Interests and (E) any and all general intangibles consisting of, arising
from or relating to any of the foregoing, and all proceeds of the conversion,
voluntary or involuntary, of the foregoing into cash, instruments, securities or
other property, including without limitation all amounts from time to time held
or invested in the Certificate Account, the Distribution Account and the
Pre-Funding Account whether in the form of cash, instruments, securities or
other property and (2) an assignment by the Company to the Trustee of any
security interest in any and all of the Seller's right (including the power to
convey title thereto), title and interest, whether now owned or hereafter
acquired, in and to the property described in the foregoing clauses (1)(A), (B),
(C), (D) and (E) granted by the Seller to the Company pursuant to the Mortgage
Loan Purchase Agreement; (c) the possession by the Trustee, or any agent of the
Trustee of Mortgage Notes or such other items of property constituting
instruments, money, negotiable documents or chattel paper shall be deemed to be
"possession by the secured party," or possession by a purchaser or a person
designated by such secured party, for purposes of perfecting the security
interest pursuant to the California Uniform Commercial Code and the Uniform
Commercial Code of any other applicable jurisdiction (including, without
limitation, Section 9-305, 8-313 or 8-321 thereof); and (d) notifications to
persons holding such property, and acknowledgments, receipts or confirmations
from persons holding such property, shall be deemed notifications to, or

bailees or agents (as applicable) of the Trustee for the purpose of perfecting
such security interest under applicable law.

                  The Company and, at the Company's direction, the Seller and
the Trustee shall, to the extent consistent with this Agreement, take such
reasonable actions as may be necessary to ensure that, if this Agreement were
deemed to create a security interest in the Mortgage Loans, the Uncertificated
REMIC I Regular Interests, the Uncertificated REMIC II Regular Interests and the
other property described above, 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. Without limiting the
generality of the foregoing, the Company shall prepare and deliver to the
Trustee not less than 15 days prior to any filing date, and the Trustee shall
forward for filing, or shall cause to be forwarded for filing, at the expense of
the Company, all filings necessary to maintain the effectiveness of any original
filings necessary under the Uniform Commercial Code as in effect in any
jurisdiction to perfect the Trustee's security interest in or lien on the
Mortgage Loans, the Uncertificated REMIC I Regular Interests and the
Uncertificated REMIC II Regular Interests, including without limitation (x)
continuation statements, and (y) such other statements as may be occasioned by
(1) any change of name of the Seller, the Company or the Trustee (such
preparation and filing shall be at the expense of the Trustee, if occasioned by
a change in the Trustee's name), or (2) any change of location of the place of
business or the chief executive office of the Seller or the Company.

                  Section 2.02. ACCEPTANCE BY TRUSTEE.

                  The Trustee acknowledges receipt of the documents referred to
in Section 2.01(b)(i) through (vi) above, declares that it, or its agent, holds
and will hold such documents and the other documents constituting a part of the
Mortgage Files delivered to it and all such other assets included in the
definition of Trust Fund in trust for the use and benefit of all present and
future Certificateholders and agrees to execute and deliver on the Closing Date
an acknowledgment of receipt in the form of Exhibit E-1 hereto (the "Initial
Certification"). The Trustee agrees, for the benefit of Certificateholders, to
review each Mortgage File delivered to it pursuant to Section 2.01(b) within 45
days after the Closing Date (or, with respect to any Subsequent Mortgage Loan or
Qualified Substitute Mortgage Loan, within 45 days after the conveyance and
assignment thereof) to ascertain that all required documents (specifically as
set forth in Section 2.01(b)), have been executed and received, and that such
documents relate to the Mortgage Loans identified on the Mortgage Loan Schedule,
as supplemented, that have been conveyed to it and shall deliver to the Company,
the Seller and the Master Servicer a certification in the form of Exhibit E-2
hereto (the "Interim Certification").

                  If within such 45 day period the Trustee finds any document or
documents constituting a part of a Mortgage File not to have been executed or
received or to be unrelated to the Mortgage Loans identified in the Mortgage
Loan Schedule, or if in the course of its review the Trustee determines that
such Mortgage File is otherwise defective in any material respect, the Trustee
shall promptly so notify the Master Servicer, the Seller and the Company. The
Seller shall correct or cure such omission or defect within 90 days from the
date the Seller was notified of such omission or defect and, if it does not
correct or cure such omission or defect within such period, the

                                       45

<PAGE>

Seller shall purchase such Mortgage Loan from REMIC I at its Repurchase Price,
in either case within 90 days from the date it was notified of such omission or
defect; provided that if the omission or defect would cause the Mortgage Loan to
be other than a "qualified mortgage" as defined in Section 860G(a)(3) of the
Code, any such cure or repurchase must occur within 90 days from the date such
breach was discovered. The Repurchase Price for any such Mortgage Loan purchased
by the Seller shall be deposited or caused to be deposited by the Master
Servicer in the Certificate Account maintained by it pursuant to Section 3.06
and, upon receipt by the Trustee of written notification of such deposit signed
by a Servicing Officer, the Trustee or any Custodian, as the case may be, shall
release to the Master Servicer the related Mortgage File and the Trustee shall
execute and deliver such instruments of transfer or assignment prepared by the
Master Servicer, in each case without recourse, as shall be necessary to vest in
the Seller or its designee, as the case may be, ownership of any Mortgage Loan
released pursuant hereto and thereafter such Mortgage Loan shall not be part of
the Trust Fund. It is understood and agreed that the obligation of the Seller to
so cure or purchase any Mortgage Loan as to which a material defect in or
omission of a constituent document exists shall constitute the sole remedy
respecting such defect or omission available to the Certificateholders or the
Trustee on behalf of Certificateholders.

                  In addition to the foregoing, the Trustee also agrees to
conduct a review during the 18 months after the Closing Date indicating the
current status of the exceptions previously indicated on the Initial
Certification and deliver a certification with respect thereto in the form
attached hereto as Exhibit E-3 (the "Final Certification"). After delivery of
the Final Certification, the Trustee and the Master Servicer shall monitor no
less frequently than monthly the status of the exceptions, if any, and deliver
updated certifications indicating the then current status of exceptions, until
all such exceptions have been eliminated.

                  Section 2.03. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE
                                MASTER SERVICER AND THE COMPANY.

                  (a) The Master Servicer hereby represents and warrants to the
Trustee for the benefit of Certificateholders, as of the Closing Date and each
Subsequent Cut-off Date, that:

                         (i) The Master Servicer is a corporation duly
         organized, validly existing and in good standing under the laws of the
         State of California and has the corporate power to own its assets and
         to transact the business in which it is currently engaged. The Master
         Servicer is duly qualified to do business as a foreign corporation and
         is in good standing in each jurisdiction in which the character of the
         business transacted by it or properties owned or leased by it requires
         such qualification and in which the failure to so qualify would have a
         material adverse effect on the business, properties, assets, or
         condition (financial or other) of the Master Servicer or the validity
         or enforceability of the Mortgage Loans;

                        (ii) The Master Servicer has the power and authority to
         execute, deliver and perform this Agreement and all of the transactions
         contemplated under this Agreement, and has taken all necessary
         corporate action to authorize the execution, delivery and performance
         of this Agreement. When executed and delivered, this Agreement will
         constitute the legal, valid and binding obligation of the Master
         Servicer enforceable in accor-

                                       46

<PAGE>

         dance with its terms, except as enforcement of such terms may be
         limited by bankruptcy, insolvency or similar laws affecting the
         enforcement of creditors' rights generally and by the availability of
         equitable remedies;

                       (iii) The Master Servicer is not required to obtain the
         consent of any other Person or any consent, license, approval or
         authorization from, or registration or declaration with, any
         governmental authority, bureau or agency in connection with the
         execution, delivery, performance, validity or enforceability of this
         Agreement, except for such consent, license, approval or authorization,
         or registration or declaration, as shall have been obtained or filed,
         as the case may be;

                        (iv) The execution and delivery of this Agreement and
         the performance of the transactions contemplated hereby by the Master
         Servicer will not violate any provision of any existing law or
         regulation or any order or decree of any court applicable to the Master
         Servicer or any provision of the certificate of incorporation or bylaws
         of the Master Servicer, or constitute a material breach of any
         mortgage, indenture, contract or other agreement to which the Master
         Servicer is a party or by which the Master Servicer may be bound;

                         (v) No litigation or administrative proceeding of or
         before any court, tribunal or governmental body is currently pending,
         or to the knowledge of the Master Servicer threatened, against the
         Master Servicer or any of its properties or with respect to this
         Agreement which, to the knowledge of the Master Servicer, has a
         reasonable likelihood of resulting in a material adverse effect on the
         transactions contemplated by this Agreement;.

                        (vi) With respect to each Mortgage Loan, the Assignment
         is in recordable form; provided, however, that the name of the assignee
         and the recording information with respect to such Mortgage Loan is
         blank and each Mortgage Loan was originated in the name of the Master
         Servicer;

                       (vii) The information set forth in the Prepayment Charge
         Schedule (including the prepayment charge summary attached thereto) is
         complete, true and correct in all material respects on the date or
         dates when such information is furnished and each Prepayment Charge is
         permissible and enforceable in accordance with its terms (except to the
         extent that the enforceability thereof may be limited by bankruptcy,
         insolvency, moratorium, receivership and other similar laws relating to
         creditors' rights generally or the collectibility thereof may be
         limited due to acceleration in connection with a foreclosure) under
         applicable law;

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

                        (ix) The Master Servicer's computer and other systems
         used in servicing mortgage loans will be modified and maintained to
         operate in a manner such that at all times, including on and after
         January 1, 2000, the Master Servicer can service the Mortgage Loans in
         accordance with the terms of this Agreement provided that the Master
         Servicer's ability

                                       47

<PAGE>

         to meet the requirements of this representation may be limited in
         circumstances where it relies (after reasonable due diligence in
         inquiring into and obtaining reasonable compliance representations) on
         third party systems which are incompatible with those of the Master
         Servicer on or after January 1, 2000.

         The foregoing representations and warranties shall survive any
termination of the Master Servicer hereunder. Upon the discovery by the Seller,
the Master Servicer, the Trustee or the Company of a breach of any of the
representations and warranties relating to the Prepayment Charges set forth in
Section 2.03(vii) or Section 2.03(viii), which materially and adversely affects
the interests of the Holders of the Class P Certificates in any Prepayment
Charge, the party discovering such breach shall give prompt written notice to
the other parties. Within 90 days of the earlier of discovery by the Master
Servicer or receipt of notice by the Master Servicer of the breach of the
representation or covenant of the Master Servicer set forth in Sections
2.03(vii) or 2.03(viii) above which materially and adversely affects the
interests of the Holders of the Class P Certificates in any Prepayment Charge,
the Master Servicer shall remedy such breach as follows: (a) if the
representation made by the Master Servicer in Section 2.03(vii) above is
breached, the Master Servicer must pay the amount of the scheduled Prepayment
Charge, for the benefit of the holder of the Class P Certificate, by depositing
such amount into the Certificate Account, net of any amount previously collected
by the Master Servicer or paid by the Master Servicer, for the benefit of the
Holders of the Class P Certificates, in respect of such Prepayment Charge; and
(b) if any of the covenants made by the Master Servicer in Section 2.03(viii)
above is breached, the Master Servicer must pay the amount of such waived
Prepayment Charge, for the benefit of the holders of the Class P Certificates,
by depositing such amount into the Certificate Account.

                  (b) The Company hereby represents and warrants to the Trustee
for the benefit of Certificateholders, as of the Closing Date and each
Subsequent Cut-off Date, that:

                         (i) The Company is a corporation duly organized,
         validly existing and in good standing under the laws of the State of
         Delaware and has the corporate power to own its assets and to transact
         the business in which it is currently engaged. The Company is duly
         qualified to do business as a foreign corporation and is in good
         standing in each jurisdiction in which the character of the business
         transacted by it or properties owned or leased by it requires such
         qualification and in which the failure to so qualify would have a
         material adverse effect on the business, properties, assets, or
         condition (financial or other) of the Company or the validity or
         enforceability of the Mortgage Loans;

                        (ii) The Company has the power and authority to execute,
         deliver and perform this Agreement and all of the transactions
         contemplated under this Agreement, and has taken all necessary
         corporate action to authorize the execution, delivery and performance
         of this Agreement. When executed and delivered, this Agreement will
         constitute the legal, valid and binding obligation of the Company
         enforceable in accordance with its terms, except as enforcement of such
         terms may be limited by bankruptcy, insolvency or similar laws
         affecting the enforcement of creditors' rights generally and by the
         availability of equitable remedies;

<PAGE>

                       (iii) The Company is not required to obtain the consent
         of any other Person or any consent, license, approval or authorization
         from, or registration or declaration with, any governmental authority,
         bureau or agency in connection with the execution, delivery,
         performance, validity or enforceability of this Agreement, except for
         such consent, license, approval or authorization, or registration or
         declaration, as shall have been obtained or filed, as the case may be;

                        (iv) The execution and delivery of this Agreement and
         the performance of the transactions contemplated hereby by the Company
         will not violate any provision of any existing law or regulation or any
         order or decree of any court applicable to the Company or any provision
         of the certificate of incorporation or bylaws of the Company, or
         constitute a material breach of any mortgage, indenture, contract or
         other agreement to which the Company is a party or by which the Company
         may be bound; and

                         (v) No litigation or administrative proceeding of or
         before any court, tribunal or governmental body is currently pending,
         or to the knowledge of the Company threatened, against the Company or
         any of its properties or with respect to this Agreement which, to the
         knowledge of the Company, has a reasonable likelihood of resulting in a
         material adverse effect on the transactions contemplated by this
         Agreement.

                  Section 2.04. ENFORCEMENT OF REPRESENTATIONS AND WARRANTIES.
The Master Servicer, on behalf of and subject to the direction of the Trustee,
shall enforce the representations and warranties and related obligations for
breaches thereof of the Seller pursuant to the Mortgage Loan Purchase Agreement.
Upon the discovery by the Seller, the Master Servicer, the Trustee or the
Company of a breach of any of the representations and warranties made in the
Mortgage Loan Purchase Agreement in respect of any Mortgage Loan, which
materially and adversely affects the interests of the Certificateholders in such
Mortgage Loan, the party discovering such breach shall give prompt written
notice to the other parties. The Master Servicer shall promptly notify the
Seller of such breach and request that, pursuant to the terms of the Mortgage
Loan Purchase Agreement, the Seller either cure such breach in all material
respects or purchase such Mortgage Loan within 90 days from the date the Seller
was notified of such breach, in each instance in accordance with the Mortgage
Loan Purchase Agreement; PROVIDED that the Seller shall, subject to the
conditions set forth in the Mortgage Loan Purchase Agreement, have the option to
substitute a Qualified Substitute Mortgage Loan or Qualified Substitute Mortgage
Loans for such Mortgage Loan if such substitution occurs within two years
following the Closing Date; provided that if the omission or defect would cause
the Mortgage Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure or repurchase must occur within 90 days
from the date such breach was discovered. Monthly Payments due with respect to
Qualified Substitute Mortgage Loans in the month of substitution shall not be
part of the Trust Fund and shall be retained by the Master Servicer and remitted
by the Master Servicer to the Seller on the next succeeding Distribution Date.
For the month of substitution, remittance to the Distribution Account pursuant
to this Agreement shall include the Monthly Payment received on a Deleted
Mortgage Loan for such month, and thereafter the Seller shall be entitled to
retain all amounts received in respect of such Deleted Mortgage Loan.
The Master Servicer shall amend or cause to be amended the Mortgage Loan
Schedule to reflect the removal of such Deleted Mortgage Loan and the
substitution of the Qualified Substitute Mortgage

                                       49

<PAGE>

Loans, and the Master Servicer shall promptly deliver the amended Mortgage Loan
Schedule to the Trustee.

                  In connection with the substitution of one or more Qualified
Substitute Mortgage Loans for one or more Deleted Mortgage Loans, the Master
Servicer shall determine the amount (such amount, a "Substitution Adjustment
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 principal balance of all such Deleted Mortgage Loans together with
accrued and unpaid interest thereon at the related Mortgage Rates (after
application of the principal portion of the Monthly Payments due in the month of
substitution that are to be remitted to the Distribution Account in the month of
substitution). The Seller shall pay the Substitution Adjustment Amount to the
Master Servicer and the Master Servicer shall deposit such Substitution
Adjustment Amount into the Certificate Account upon receipt.

                  Upon receipt by the Trustee of written notification, signed by
a Servicing Officer, of the deposit of such Repurchase Price or of such
substitution of a Qualified Substitute Mortgage Loan and deposit of any
applicable Substitution Adjustment Amount as provided above, the Trustee on
behalf of the Trust Fund shall release to the Seller the related Mortgage File
for the Mortgage Loan being repurchased or substituted for and the Trustee shall
execute and deliver such instruments of transfer or assignment prepared by the
Master Servicer, in each case without recourse, as shall be necessary to vest in
the Seller or its designee ownership of such Mortgage Loan released pursuant
hereto, and thereafter such Mortgage Loan shall not be an asset of the Trust
Fund.

                  It is understood and agreed that the obligation of the Seller
to cure any breach with respect to or to repurchase or substitute for, any
Mortgage Loan as to which such a breach has occurred and is continuing shall
constitute the sole remedy respecting such breach available to the Company, the
Trust Fund or the Certificateholders (or the Trustee on behalf of the
Certificateholders) against the Seller.

prior to the related Subsequent Cut-off Date. The transfer to the Trustee by the
Company of the Subsequent Mortgage Loans identified on the related Mortgage Loan
Schedule shall be absolute and is intended by the Company, the Master Servicer,
the Trustee and the Certificateholders to constitute and to be treated as a sale
of the Subsequent Mortgage Loans by the Company to the Trust Fund.

                  The "Purchase Price" to be paid by the Trustee from amounts
released from the Pre- Funding Account shall be one-hundred percent (100%) of
the aggregate unpaid principal balances of the Subsequent Mortgage Loans so
transferred as of the close of business on the related Subsequent Transfer
Dates. This Agreement shall constitute a fixed-price purchase contract in
accordance with Section 860G(a)(3)(A)(ii) of the Code.

                  (b) Following the transfer to the Trust Fund of the Subsequent
Mortgage Loans and other property and rights related thereto described in
Section 2.09(a) above, the Subsequent Mortgage Loans and all Mortgage Loans and
obligations in the Trust Fund, as a whole, will have the characteristics
described in the Company's Prospectus Supplement, dated March 31, 2000 relating
to the Offered Certificates. No transfer of the Subsequent Mortgage Loans and
property and rights related thereto described in Section 2.09(a) above shall be
made to the Trust Fund during the Pre- Funding Period if it would result in the
downgrade of the rating of any Class of Offered Certificates. All Subsequent
Mortgage Loans shall meet the same terms and conditions for eligibility as those
Mortgage Loans transferred to the Trust Fund as of the Closing Date, which terms
and conditions shall have been approved by the Rating Agencies and which terms
and conditions may be changed if such changes receive prior approval either by a
vote of the Certificateholders of at least a majority of the Offered
Certificates or by the Rating Agencies. In order to ensure that the
characteristics of the Subsequent Mortgage Loans are substantially similar to
Mortgage Loans which were acquired as of the Closing Date, the characteristics
of the Subsequent Mortgage Loans will either be monitored by a credit support
provider or other insurance provider which is independent of the Seller and the
Company or an independent accountant retained by the sponsor will provide the
Seller and the Company with a letter (with copies provided to the Rating
Agencies, the underwriters of the Certificates and the Trustee) stating whether
or not the characteristics of the Subsequent Mortgage

                                       52

<PAGE>

Loans conform to the characteristics of such obligations described in the
Company's Prospectus, dated August 10, 1998, and the Prospectus Supplement,
dated March 31, 2000, relating to the Offered Certificates and this Agreement,
and, in preparing such letter, the independent accountant will use the same type
of procedures as were applicable to the Initial Mortgage Loans.

                                   ARTICLE III

                 ADMINISTRATION AND SERVICING OF MORTGAGE LOANS

                  Section 3.01. MASTER SERVICER TO ASSURE SERVICING. (a) The
Master Servicer shall service and administer the Mortgage Loans, the Prepayment
Charges and any REO Property in accordance with this Agreement and its normal
servicing practices, which generally shall conform to the standards of an
institution prudently servicing mortgage loans similar to the Mortgage Loans for
its own account and shall have full authority to do anything it reasonably deems
appropriate or desirable in connection with such servicing and administration.
The Master Servicer may perform its responsibilities relating to servicing
through other agents or independent contractors, but shall not thereby be
released from any of its responsibilities as hereinafter set forth. The
authority of the Master Servicer, in its capacity as Master Servicer, and any
Subservicer acting on its behalf, shall include, without limitation, the power
to (i) consult with and advise any Subservicer regarding administration of a
related Mortgage Loan, (ii) approve any recommendation by a Subservicer to
foreclose on a related Mortgage Loan, (iii) supervise the filing and collection
of insurance claims and take or cause to be taken such actions on behalf of the
insured Person thereunder as shall be reasonably necessary to prevent the denial
of coverage thereunder, and (iv) effectuate foreclosure or other conversion of
the ownership of the Mortgaged Property securing a related Mortgage Loan,
including the employment of attorneys, the institution of legal proceedings, the
collection of deficiency judgments, the acceptance of compromise proposals, the
filing of claims under any insurance policy and any other matter pertaining to a
Delinquent Mortgage Loan. The authority of the Master Servicer shall include, in
addition, the power on behalf of the Certificateholders, the Trustee or either
of them to (i) execute and deliver customary consents or waivers and other
instruments and documents, (ii) consent to transfer of any related Mortgaged
Property and assumptions of the related Mortgage Loans (in the manner provided
in this Agreement) and (iii) collect any Insurance Proceeds and Liquidation
Proceeds. Without limiting the generality of the foregoing, the Master Servicer
and any Subservicer acting on its behalf may, and is hereby authorized and
empowered by the Trustee to, execute and deliver, on behalf of itself, the
Certificateholders, the Trustee or either of them, any instruments of
satisfaction, cancellation, partial or full release, discharge and all other
comparable instruments, with respect to the Mortgage Loans, any related
insurance policies and the accounts related thereto, and the Mortgaged
Properties. The Master Servicer may exercise this power in its own name or in
the name of a Subservicer.

                  (b) Notwithstanding the provisions of Subsection 3.01(a), the
Master Servicer shall not take any action adverse to the rights and interests of
the Trustee or the Certificateholders under this Agreement.

                  (c) The Trustee shall furnish the Master Servicer with any
powers of attorney and other documents in the form provided by it which are
necessary or appropriate to enable the Master Servicer to service and administer
the related Mortgage Loans and REO Property.

                  (d) Notwithstanding anything in this Agreement to the
contrary, subject to Section 3.06(a), the Master Servicer shall not permit any
modification with respect to any Mortgage Loan that would both constitute a sale
or exchange of such Mortgage Loan within the meaning of Section

                                       54

<PAGE>

1001 of the Code (and any proposed, temporary or final regulations promulgated
thereunder) and cause either REMIC I, REMIC II or REMIC III to fail to qualify
as a REMIC under the Code.

                  (e) To the extent consistent with the requirements of Section
3.01, the Master Servicer shall waive in whole or in part (or permit a
subservicer to waive) a Prepayment Charge only under the following
circumstances: (i) such waiver is standard and customary in servicing similar
Mortgage Loans and (ii) either (A) such waiver would, in the reasonable judgment
of the Master Servicer, maximize recovery of total proceeds taking into account
the value of such Prepayment Charge and the related Mortgage Loan and, if such
waiver is made in connection with a refinancing of the related Mortgage Loan,
such refinancing is related to a default or a reasonably foreseeable default or
(B) such waiver is made in connection with a refinancing of the related Mortgage
Loan unrelated to a default or a reasonably foreseeable default where (x) the
related Mortgagor has stated to the Master Servicer or an applicable subservicer
an intention to refinance the related Mortgage Loan and (y) the Master Servicer
has concluded in its reasonable judgment that the waiver of such Prepayment
Charge would induce such Mortgagor to refinance with the Master Servicer. If a
Prepayment Charge is waived as permitted by meeting the standards described in
clauses (i) and (ii)(B) above, then the Master Servicer is required to pay the
amount of such waived Prepayment Charge, for the benefit of the Holders of the
Class P Certificates, by depositing such amount into the Certificate Account
together with and at the time that the amount prepaid on the related Mortgage
Loan is required to be deposited into the Certificate Account. Notwithstanding
any other provisions of this Agreement, any payments made by the Master Servicer
in respect of any waived Prepayment Charges pursuant to clauses (i) and (ii)(B)
shall be deemed to be paid outside of REMIC I.

                  Section 3.02. SUBSERVICING AGREEMENTS BETWEEN MASTER SERVICER
                                AND SUBSERVICER.

                  (a) The Master Servicer may enter into Subservicing Agreements
with Subservicers for the servicing and administration of the Mortgage Loans and
for the performance of any and all other activities of the Master Servicer
hereunder. Each Subservicer shall be either (i) an institution the accounts of
which are insured by the FDIC or (ii) another entity that engages in the
business of originating or servicing mortgage loans comparable to the Mortgage
Loans, and in either case shall be authorized to transact business in the state
or states in which the related Mortgaged Properties it is to service are
situated, if and to the extent required by applicable law to enable the
Subservicer to perform its obligations hereunder and under the Subservicing
Agreement. Any Subservicing Agreement entered into by the Master Servicer shall
include the provision that such Agreement may be immediately terminated (x) with
cause and without any termination fee by any Master Servicer hereunder or (y)
without cause in which case the Master Servicer but not the Trust Fund shall be
responsible for any termination fee or penalty resulting therefrom. In addition,
each Subservicing Agreement shall provide for servicing of the Mortgage Loans
consistent with the terms of this Agreement.

                  (b) As part of its servicing activities hereunder, the Master
Servicer, for the benefit of the Trustee and the Certificateholders, shall
enforce the obligations of each Subservicer under the related Subservicing
Agreement. Such enforcement, including, without limitation, the legal
prosecution of claims, termination of Subservicing Agreements and the pursuit of
other appropriate remedies, shall be in such form and carried out to such an
extent and at such time as the

                                       55

<PAGE>

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

                  Section 3.03. SUCCESSOR SUBSERVICERS. The Master Servicer
shall be entitled to terminate any Subservicing Agreement that may exist in
accordance with the terms and conditions of such Subservicing Agreement and
without any limitation by virtue of this Agreement; PROVIDED, HOWEVER, that upon
termination, the Master Servicer shall either assume the duties of the
Subservicer in respect of the related Mortgage Loans or enter into a contract
with a successor Subservicer meeting the requirements of Section 3.02(a),
pursuant to which such successor Subservicer will be bound by all relevant terms
of the related Subservicing Agreement pertaining to the servicing of such
Mortgage Loans.

                  Section 3.04. LIABILITY OF THE MASTER SERVICER. (a)
Notwithstanding any Subservicing Agreement, any of the provisions of this
Agreement relating to agreements or arrangements between the Master Servicer and
a Subservicer or any other agent or independent contractor or reference to
actions taken through a Subservicer or otherwise, the Master Servicer shall
under all circumstances remain obligated and primarily liable to the Trustee and
the Certificateholders for the servicing and administering of the Mortgage Loans
and any REO Property in accordance with this Agreement. The obligations and
liability of the Master Servicer shall not be diminished by virtue of
Subservicing Agreements or by virtue of indemnification of the Master Servicer
by any Subservicer, or any other Person. The obligations and liability of the
Master Servicer shall remain of the same nature and under the same terms and
conditions as if the Master Servicer alone were servicing and administering the
related Mortgage Loans. The Master Servicer shall, however, be entitled to enter
into indemnification agreements with any Subservicer or other Person and nothing
in this Agreement shall be deemed to limit or modify such indemnification. For
the purposes of this Agreement, the Master Servicer shall be deemed to have
received any payment on a Mortgage Loan on the date the Subservicer received
such payment; PROVIDED, HOWEVER, that this sentence shall not apply to the
Trustee acting as the Master Servicer; PROVIDED, FURTHER, however, that the
foregoing provision shall not affect the obligation of the Master Servicer if it
is also the Trustee to advance amounts which are not Nonrecoverable Advances.

                  (b) Any Subservicing Agreement that may be entered into and
any transactions or services relating to the Mortgage Loans involving a
Subservicer in its capacity as such shall be deemed to be between the
Subservicer and the Master Servicer alone, and the Trustee and the
Certificateholders shall not be deemed parties thereto and shall have no claims,
rights, obligations, duties or liabilities with respect to the Subservicer
except as set forth in Section 3.05.

                  Section 3.05. ASSUMPTION OR TERMINATION OF SUBSERVICING
                                AGREEMENTS BY TRUSTEE.

(a) If the Trustee or its designee shall assume the servicing obligations of the
Master Servicer in accordance with Section 7.02 below, the Trustee, to the
extent necessary to permit the Trustee to

                                       56

<PAGE>

carry out the provisions of Section 7.02 with respect to the Mortgage Loans,
shall succeed to all of the rights and obligations of the Master Servicer under
each of the Subservicing Agreements. In such event, the Trustee or its designee
as the successor Master Servicer shall be deemed to have assumed all of the
Master Servicer's rights and obligations therein and to have replaced the Master
Servicer as a party to such Subservicing Agreements to the same extent as if
such Subservicing Agreements had been assigned to the Trustee or its designee as
a successor Master Servicer, except that the Trustee or its designee as a
successor Master Servicer shall not be deemed to have assumed any obligations or
liabilities of the Master Servicer arising prior to such assumption (other than
the obligation to make any Monthly Advances) and the Master Servicer shall not
thereby be relieved of any liability or obligations under such Subservicing
Agreements arising prior to such assumption.
The Trustee shall be entitled as successor Master Servicer to receive the
servicing compensation provided under Section 3.15, accruing after its
assumption of the servicing, as the Master Servicer would be entitled to
receive.

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

                  Section 3.06. COLLECTION OF MORTGAGE LOAN PAYMENTS. (a) The
Master Servicer shall use reasonable efforts to collect or cause to be collected
all payments required under the terms and provisions of the Mortgage Loans and
shall follow collection procedures generally comparable to the collection
procedures of prudent mortgage lenders servicing mortgage loans similar to the
Mortgage Loans for their own account to the extent such procedures shall be
consistent with this Agreement. Consistent with the foregoing, the Master
Servicer may in its discretion (i) waive or permit to be waived any late payment
charge, Prepayment Charge (subject to the waiver standard set forth in Section
3.01(e)), assumption fee, or any penalty interest or similar charge or fee in
connection with the prepayment of a Mortgage Loan and (ii) suspend or reduce or
permit to be suspended or reduced regular monthly payments for a period of up to
twelve months, or arrange or permit an arrangement with a Mortgagor for a
scheduled liquidation of delinquencies; PROVIDED, HOWEVER, that the Master
Servicer may permit the foregoing only if it believes, in good faith, that such
action or actions will be in the best interest of the Certificateholders. In the
event the Master Servicer shall consent to the deferment of the Due Dates for
payments due on a Mortgage Note, the Master Servicer shall nonetheless make a
Monthly Advance to the same extent as if such installment were due, owing and
delinquent and had not been deferred; PROVIDED, HOWEVER, that the obligation of
the Master Servicer to make a Monthly Advance shall apply only to the extent
that the Master Servicer believes that such Monthly Advance is not a
Nonrecoverable Advance. Consistent with the terms of this Agreement, the Master
Servicer may also waive, modify or vary any term of any Mortgage Loan or consent
to the postponement of strict compliance with any such term or in any manner
grant indulgence to any Mortgagor if in the Master Servicer's determination such
waiver,

                                       57

<PAGE>

modification, postponement or indulgence is not materially adverse to the
interests of the Certificateholders; PROVIDED, HOWEVER, that the Master 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 (other than in connection
with the liquidation of the related Mortgage Loan or with prepayments to the
extent any related reamortization is not inconsistent with the terms of the
Mortgage Loan), or extend the final maturity date of such Mortgage Loan, unless
such Mortgage Loan is in default or, in the judgment of the Master Servicer,
such default is reasonably foreseeable.

                  (b) The Master Servicer shall establish a segregated account
in the name of the Trustee (the "Certificate Account"), which shall be an
Eligible Account, in which the Master Servicer shall deposit or cause to be
deposited any amounts representing interest payments due and principal
collections received by it subsequent to the related Cut-off Date (other than in
respect of the payments referred to in the following paragraph), within one
Business Day of receipt of good funds in respect thereof, including the
following payments and collections received or made by it (without duplication):

                           (i) the aggregate Repurchase Price of the Mortgage
Loans purchased pursuant to Section 3.18;

                           (ii) Insurance Proceeds and Net Liquidation Proceeds;

                           (iii) the aggregate Repurchase Price of any Mortgage
Loans repurchased by the Seller pursuant to the Mortgage Loan Purchase
Agreement, and all Substitution Adjustment Amounts required to be deposited in
connection with the substitution of a Qualified Substitute Mortgage Loan
pursuant to the Mortgage Loan Purchase Agreement;

                           (iv) amounts required to be paid pursuant to Section
3.10 in respect of a blanket insurance policy deductible, Section 10.02 in
respect of indemnification of the Trust Fund or Section 9.01 in respect of the
Termination Price;

                           (v) any Monthly Advances and any Compensating
Interest payments;

                           (vi) any amounts required to be deposited pursuant to
Section 3.20 in connection with any REO Property; and

                           (vii) all Prepayment Charges collected by the Master
Servicer in connection with the Principal Prepayment of any of the Mortgage
Loans and any Master Servicer Prepayment Charge Payment Amount.

PROVIDED, HOWEVER, that with respect to each Due Period, the Master Servicer
shall be permitted to retain from payments in respect of interest on the
Mortgage Loans the Servicing Fee for such Due Period. The foregoing requirements
respecting deposits into the Certificate Account are exclusive, it being
understood that, without limiting the generality of the foregoing, the Master
Servicer need not deposit in the Certificate Account assumption and modification
fees or late charges payable by

                                       58

<PAGE>

Mortgagors, or Foreclosure Profits, each as further described in Section 3.15,
or amounts received by the Master Servicer for the accounts of Mortgagors for
application towards the payment of taxes, insurance premiums, assessments and
similar items. In the event any amount not required to be deposited in the
Certificate Account is so deposited, the Master Servicer may at any time (prior
to being terminated under this Agreement) withdraw such amount from the
Certificate Account, any provision herein to the contrary notwithstanding. The
Master Servicer shall keep records that accurately reflect the funds on deposit
in the Certificate Account that have been identified by it as being attributable
to the Mortgage Loans and shall hold all collections in the Certificate Account
for the benefit of the Trustee and the Certificateholders, as their interests
may appear.

                  Any interest or investment earnings on funds held in the
Certificate Account shall be for the account of the Master Servicer and may only
be withdrawn from the Certificate Account by the Master Servicer immediately
following its monthly remittance of the amount required to be remitted pursuant
to Section 4.01 to the Trustee. Any reference herein to amounts on deposit in
the Certificate Account shall refer to amounts net of such interest or
investment earnings.

                  Section 3.07 WITHDRAWALS FROM THE CERTIFICATE ACCOUNT. (a) The
Master Servicer shall, from time to time as provided herein, make withdrawals
from the Certificate Account of amounts on deposit therein pursuant to Section
3.06 for the following purposes (without duplication):

                           (i) to deposit in the Distribution Account, by the
         Determination Date prior to each Distribution Date, the amount required
         to be distributed pursuant to Section 4.01 for such Distribution Date;

                           (ii) to pay to itself out of each payment received on
         account of interest on a Mortgage Loan as contemplated by Section 3.15,
         an amount equal to the related Servicing Fee (to the extent not
         retained pursuant to Section 3.06);

                           (iii) to pay to itself, the Seller or other entity
         entitled thereto, with respect to any Mortgage Loan or REO Property
         that has been purchased or otherwise transferred to the Seller, the
         Master Servicer or such other entity, all amounts received thereon and
         not required to be distributed to Certificateholders as of the date on
         which the related Repurchase Price is determined;

                           (iv) to reimburse the Master Servicer for (a) any
         Monthly Advance or Servicing Advance of its own funds, the right of the
         Master Servicer to reimbursement pursuant to this subclause (iv) being
         limited to amounts received on a particular Mortgage Loan (including,
         for this purpose, the Repurchase Price therefor and Liquidation
         Proceeds) which represent late payments or recoveries of the principal
         of or interest on such Mortgage Loan respecting which such Monthly
         Advance or Servicing Advance was made or (b) subject to Section 3.22
         and Section 4.09, any unreimbursed Monthly Advances or Servicing
         Advances to the extent of funds held in the Certificate Account for
         future distribution that were not included in the Available
         Distribution Amount for the preceding Distribution Date;

                                       59

<PAGE>

                           (v) to reimburse the Master Servicer for any
         Nonrecoverable Advance previously made, and not reimbursed pursuant to
         Subsection 3.07(a)(iv);

                           (vi) to pay to itself interest or investment earnings
         in respect of Eligible Investments or on funds deposited in the
         Certificate Account;

                           (vii) to pay to the Person entitled thereto any
         amounts reimbursable from the Trust Fund pursuant to Section 6.03 or
         8.05;

                           (viii) to withdraw any other amount deposited in the
         Certificate Account that was not required to be deposited therein
         pursuant to Section 3.06; and

                           (ix) to clear and terminate the Certificate Account
         pursuant to Section 9.01.

In connection with withdrawals pursuant to clauses (ii), (iii) and (iv), the
Master Servicer's entitlement thereto is limited to collections or other
recoveries on the related Mortgage Loan, and the Master Servicer shall keep and
maintain separate accounting, on a Mortgage Loan by Mortgage Loan basis, for the
purpose of justifying any withdrawal from the Certificate Account pursuant to
such clauses.

         (b) So long as no Event of Default shall have occurred and be
continuing, and consistent with any requirements of the Code, the funds held in
the Certificate Account may be invested by the Master Servicer (to the extent
practicable) in Eligible Investments, as directed in writing to the Trustee by
the Master Servicer. Funds in the Certificate Account must be available for
withdrawal without penalty, and any Eligible Investments must mature not later
than the Business Day immediately preceding the Determination Date next
following the date of such investment (except that if any of such Eligible
Investments is an obligation of the institution that maintains the related
Certificate Account, then such Eligible Investments shall mature not later than
such Determination Date) and shall not be sold or disposed of prior to its
maturity. All Eligible Investments in which funds in the related Certificate
Account are invested must be held by or registered in the name of the Trustee in
trust for the Certificateholders. All interest or other earnings from funds on
deposit in the related Certificate Account (or any Eligible Investments thereof)
shall be the exclusive property of the Master Servicer, and may be withdrawn
from the related Certificate Account pursuant to clause (vi) above and the last
paragraph of Section 3.06(b) above. The amount of any net losses incurred in
connection with the investment of funds in the Certificate Account in Eligible
Investments shall be deposited in the related Certificate Account by the Master
Servicer from its own funds immediately as realized without reimbursement
therefor.

                  Section 3.08. COLLECTION OF TAXES, ASSESSMENTS AND SIMILAR
                                ITEMS; SERVICING ACCOUNTS.

                  (a) The Master Servicer shall establish and maintain one or
more Servicing Accounts. The Master Servicer will deposit and retain therein all
collections from the Mortgagors for the payment of taxes, assessments, insurance
premiums or comparable items.

                                       60

<PAGE>

                  (b) The deposits in the Servicing Accounts shall be held in
trust by the Master Servicer (and its successors and assigns) in the name of the
Trustee. Such Servicing Accounts shall be Eligible Accounts and if permitted by
applicable law, invested in Eligible Investments held in trust by the Master
Servicer as described above and maturing, or subject to redemption or
withdrawal, no later than the date on which such funds are required to be
withdrawn, and in no event later than 45 days after the date of investment.
Withdrawals of amounts from the Servicing Accounts may be made only to effect
timely payment of taxes, assessments, insurance premiums or comparable items, to
reimburse the Master Servicer for any Servicing Advances made with respect to
such items, to refund to any Mortgagors any sums as may be determined to be
overages, to pay interest, if required, to Mortgagors on balances in the
Servicing Accounts or to clear and terminate the Servicing Accounts at or any
time after the termination of this Agreement. Any advances of such payments
shall constitute Servicing Advances.

                  Section 3.09 RESERVED.

                  Section 3.10 MORTGAGE IMPAIRMENT INSURANCE. In the event that
the Master Servicer shall obtain and maintain a blanket policy insuring against
fire and hazards of extended coverage on all of the Mortgage Loans, then, to the
extent such policy names the Master Servicer as loss payee and provides coverage
in an amount equal to the aggregate unpaid principal balance on the related
Mortgage Loans without co-insurance, and otherwise complies with the
requirements of Section 3.11 below, the Master Servicer shall be deemed
conclusively to have satisfied its obligations with respect to fire and hazard
insurance coverage under Section 3.11 below, it being understood and agreed that
such blanket policy may contain a deductible clause, in which case the Master
Servicer shall, in the event that there shall not have been maintained on the
related Mortgaged Property a policy complying with Section 3.11 below, and there
shall have been a loss which would have been covered by such policy, deposit in
the Certificate Account without reimbursement therefor, the difference, if any,
between the amount that would have been payable under a policy complying with
Section 3.11 below and the amount paid under such blanket policy.

                  Section 3.11 MAINTENANCE OF HAZARD INSURANCE AND FIDELITY
COVERAGE. (a) The Master Servicer shall maintain, or cause each Subservicer to
maintain, with respect to each Mortgage Loan and each REO Property, in full
force and effect hazard insurance (fire insurance with extended coverage) equal
to the least of the principal balance of the Mortgage Loan, the current
replacement cost of the Mortgaged Property and the full insurable value of the
Mortgaged Property, and containing a standard mortgagee clause, PROVIDED,
HOWEVER, that the amount of hazard insurance may not be less than the amount
necessary to prevent loss due to the application of any co-insurance provision
of the related policy.

                  (b) All policies required hereunder shall be endorsed with
standard mortgagee clauses with losses payable to the Master Servicer. Any
amounts collected by the Master Servicer or a Subservicer under any such hazard
insurance policy (other than amounts to be applied to the restoration or repair
of the Mortgaged Property or amounts released to the Mortgagor in accordance
with the Master Servicer's or a Subservicer's normal servicing procedures, the
Mortgage Note, the Mortgage or applicable law) shall be deposited into the
Certificate Account, for transmittal to the Distribution Account, subject to
withdrawal pursuant to Section 3.07.

                                       61

<PAGE>

                  (c) Any cost incurred by a Master Servicer in maintaining any
such hazard insurance policy shall not be added to the amount owing under the
Mortgage Loan for the purpose of calculating monthly distributions to
Certificateholders, notwithstanding that the terms of the Mortgage Loan so
permit. Such costs shall constitute Servicing Advances and shall be recoverable
by the Master Servicer in accordance with Section 3.07.

                  (d) No earthquake or other additional insurance shall be
required of any Mortgagor or maintained on REO Property other than pursuant to
such applicable laws and regulations as shall at any time be in force and
require such additional insurance. If, at the time of origination of the
Mortgage Loan or at any subsequent time, the Mortgaged Property or REO Property
is located in a federally designated special flood hazard area, the Master
Servicer shall use reasonable efforts to cause flood insurance (to the extent
available and in accordance with mortgage servicing industry practice) to be
maintained thereon. Such flood insurance shall be in an amount equal to the
lesser of (i) the principal balance of the related Mortgage Loan and (ii) the
minimum amount required under the terms of coverage to compensate for any damage
or loss on a replacement cost basis, but not more than the maximum amount of
such insurance available for the related Mortgaged Property or REO Property
under either the regular or emergency programs of the National Flood Insurance
Program (assuming that the area in which such Mortgaged Property or REO Property
is located is participating in such program).

                  (e) If insurance has not been maintained and should have been
maintained in accordance with the limitations set forth in Subsections 3.11 (a)
and (d), and there shall have been a loss which would have been covered by such
insurance had it been maintained, the Master Servicer shall pay for any
resulting loss without reimbursement therefor.

                  (f) The Master Servicer shall present, or cause the related
Subservicer to present, claims under any related hazard insurance or flood
insurance policy.

                  (g) The Master Servicer shall obtain and maintain at its own
expense and for the duration of this Agreement a blanket fidelity bond and
errors and omissions insurance policy acceptable to Fannie Mae or Freddie Mac
covering such Master Servicer's officers, employees and other persons acting on
its behalf in connection with its activities under this Agreement. The Master
Servicer shall promptly notify the Trustee of any material change in the terms
of such bond or policy.
Upon the request of the Trustee, the Master Servicer shall provide to the
Trustee a certified true copy of such fidelity bond and insurance policy. If any
such bond or policy ceases to be in effect, the Master Servicer shall, to the
extent possible, give the Trustee ten days' notice prior to any such cessation
and shall use reasonable efforts to obtain a comparable replacement bond or
policy, as the case may be.

                  Section 3.12 DUE-ON-SALE CLAUSES; ASSUMPTION AGREEMENTS. (a)
If the Master Servicer receives notice that a Mortgaged Property relating to a
Mortgage Loan has been or is about to be conveyed by the Mortgagor, the Master
Servicer shall enforce any due-on-sale clause contained in the related Mortgage
to the extent permitted under the terms of the related Mortgage Note and by
applicable law. If the Master Servicer reasonably believes that such due-on-sale
clause cannot be enforced under applicable law or if the Mortgage Loan does not
contain a due-on-sale clause, the

                                       62

<PAGE>

Master Servicer is authorized to consent to a conveyance subject to the lien of
the Mortgage, and to take or enter into an assumption agreement from or with the
Person to whom such property has been or is about to be conveyed, pursuant to
which such Person becomes liable under the related Mortgage Note and unless
prohibited by applicable law, such Mortgagor remains liable thereon. In
connection with any such assumption, no material term of the related Mortgage
Note may be changed. The Master Servicer shall notify the Trustee, whenever
practicable, before the completion of such assumption agreement, and shall
forward to the Trustee the original of such assumption agreement, which shall be
added by the Trustee to the related Mortgage File and which shall, for all
purposes, be considered a part of such Mortgage File to the same extent as all
other documents and instruments constituting a part thereof. Any fee or
additional interest collected by the Master Servicer for consenting to any such
conveyance or entering into any such assumption agreement may be retained by the
Master Servicer as additional servicing compensation.

                  (b) Notwithstanding the foregoing paragraph or any other
provision of this Agreement, the Master Servicer shall not be deemed to be in
default, breach or any other violation of its obligations hereunder by reason of
any assumption of a Mortgage Loan by operation of law or any conveyance by the
Mortgagor of the related Mortgaged Property or assumption of a Mortgage Loan
which the Master Servicer reasonably believes it may be restricted by law from
preventing, for any reason whatsoever or if the exercise of such right would
impair or threaten to impair any recovery under any applicable insurance policy.

                  Section 3.13 REALIZATION UPON DEFAULTED MORTGAGE LOANS. (a)
The Master Servicer shall foreclose upon or otherwise comparably convert the
ownership of properties securing any Mortgage Loans that come into and continue
in default and as to which the Master Servicer has decided in its good faith
judgment that such action is in the best interest of the Trust Fund, except that
the Master Servicer shall not foreclose upon or otherwise comparably convert a
Mortgaged Property if there is evidence of toxic waste or other environmental
hazards thereon, unless the Master Servicer follows the procedures in Subsection
3.13(c) below. In connection with such foreclosure or other conversion, the
Master Servicer shall use reasonable efforts to preserve REO Property and to
realize upon defaulted Mortgage Loans in such a manner as to maximize the
receipt of principal and interest by the Certificateholders, taking into
account, among other things, the timing of foreclosure and the considerations
set forth in Subsection 3.13(b). The foregoing is subject to the proviso that
the Master Servicer shall not be required to expend its own funds in connection
with any foreclosure or towards the restoration of any property unless it
determines in good faith (i) that such restoration or foreclosure will increase
Net Liquidation Proceeds, and (ii) that such expenses will constitute Servicing
Advances and will be recoverable to it pursuant to Section 3.07. The Master
Servicer shall be responsible for all other costs and expenses incurred by it in
any such proceedings; PROVIDED, HOWEVER, that it shall be entitled to receive
Foreclosure Profits as additional servicing compensation.

                  (b) The Trust Fund shall not acquire any real property (or any
personal property incident to such real property) except in connection with a
default or imminent default of a Mortgage Loan. In the event that the Trust Fund
acquires any real property (or personal property incident to such real property)
in connection with a default or imminent default of a Mortgage Loan, such

                                       63

<PAGE>

property shall be disposed of by the Trustee on behalf of the Trust Fund in
accordance with Section 3.20.

                  (c) With respect to any Mortgage Loan as to which the Master
Servicer has received notice of, or has actual knowledge of, the presence of any
toxic or hazardous substance on the Mortgaged Property, the Master Servicer
shall promptly notify the Trustee and shall act in accordance with any
directions provided by the Trustee. Notwithstanding the preceding sentence of
this Section 3.13(c), with respect to any Mortgage Loan described by such
sentence, the Master Servicer shall, if requested by the Trustee, obtain and
deliver to the Trustee an environmental audit report prepared by a Person who
regularly conducts environmental audits using customary industry standards. The
Master Servicer shall be entitled to reimbursement for such report pursuant to
Section 3.07. If the Trustee has not provided directions to the Master Servicer
in connection with any such Mortgage Loan within 30 days of a request by the
Master Servicer for such directions and instructions, then the Master Servicer
shall take such action as it deems to be in the best economic interest of the
Trust Fund, including the release of such Mortgaged Property from the lien of
the related Mortgage. The parties hereto acknowledge that the Master Servicer
shall not acquire possession of or title to, or commence any proceedings to
acquire possession of or title to, or take any other action with respect to, any
Mortgaged Property, if the Trustee could reasonably be considered to be a
responsible party for any liability arising from the presence of any toxic or
hazardous substance on the Mortgaged Property, unless the Trustee has been
indemnified to its reasonable satisfaction against such liability.

                  Section 3.14 TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES.
(a) Upon payment in full of any Mortgage Loan or the receipt by the Master
Servicer of a notification that payment in full will be escrowed in a manner
customary for such purposes, the Master Servicer will immediately notify the
Trustee by a certification signed by a Servicing Officer (which certification
shall include a statement to the effect that all amounts received or to be
received in connection with such payment which are required to be deposited in
the Certificate Account have been or will be so deposited) and shall request
delivery to the Master Servicer of the Mortgage File. Upon receipt of such
certification and request, the Trustee shall promptly release the related
Mortgage File to the Master Servicer and execute and deliver to the Master
Servicer, without recourse, the request for reconveyance, deed of reconveyance
or release or satisfaction of mortgage or such instrument releasing the lien of
the Mortgage (furnished by the Master Servicer), together with the Mortgage Note
with written evidence of cancellation thereon.

                  (b) From time to time as is appropriate for the servicing or
foreclosure of any Mortgage Loan or collection under an insurance policy, the
Master Servicer may deliver to the Trustee a Request for Release signed by a
Servicing Officer on behalf of the Master Servicer in substantially the form
attached as Exhibit D hereto. Upon receipt of the Request for Release, the
Trustee shall deliver the Mortgage File or any document therein to the Master
Servicer as bailee for the Trustee.

                  (c) The Master Servicer shall cause each Mortgage File or any
document therein released pursuant to Subsection 3.14(b) to be returned to the
Trustee when the need therefor no longer exists, unless the Mortgage Loan has
become a Liquidated Mortgage Loan and the Net

                                       64

<PAGE>

Liquidation Proceeds relating to the Mortgage Loan have been deposited in the
Certificate Account. Prior to return of a Mortgage File or any document to the
Trustee, the Master Servicer shall retain such file or document in its
constructive control as bailee for the Trustee. If a Mortgage Loan becomes a
Liquidated Mortgage Loan, the Trustee shall deliver the Request for Release with
respect thereto to the Master Servicer upon deposit of the related Net
Liquidation Proceeds in the Certificate Account.

                  (d) The Trustee shall execute and deliver to the Master
Servicer any court pleadings, requests for trustee's sale or other documents
presented to it by the Master Servicer necessary to (i) the foreclosure or
trustee's sale with respect to a Mortgaged Property; (ii) any legal action
brought to obtain judgment against any Mortgagor on the Mortgage Note or
Mortgage; (iii) obtain a deficiency judgment against the Mortgagor; or (iv)
enforce any other rights or remedies provided by the Mortgage Note or Mortgage
or otherwise available at law or equity. Together with such documents or
pleadings, the Master Servicer shall deliver to the Trustee a certificate of a
Servicing Officer in which it requests the Trustee to execute the pleadings or
documents.

                  Section 3.15 SERVICING COMPENSATION. (a) As compensation for
its activities hereunder, the Master Servicer shall be entitled to receive the
Servicing Fee with respect to each Mortgage Loan it services.

                  (b) The Master Servicer may retain additional servicing
compensation in the form of tax service fees, fees for statement of account or
payoff, late payment charges, bad check charges, assumption fees, modification
fees or any other servicing-related fees (other than Prepayment Charges), to the
extent such fees are collected from the related Mortgagors, and Foreclosure
Profits. The Master Servicer shall be required to pay all expenses it incurs in
connection with its servicing activities under this Agreement and shall not be
entitled in connection with its servicing activities under this Agreement to
reimbursement except as provided in this Agreement.

                  Section 3.16 ANNUAL STATEMENTS OF COMPLIANCE. Within 120 days
after December 31 of each year, commencing in December 2000, the Master Servicer
at its own expense shall deliver to the Trustee, with a copy to the Rating
Agencies, an Officer's Certificate stating, as to the signer thereof, that (i) a
review of the activities of the Master Servicer during the most recently
completed calendar year and of its performance under this Agreement has been
made under such officer's supervision, (ii) to the best of such officer's
knowledge, based on such review, the Master Servicer has fulfilled all of its
obligations under this Agreement for such year (including but not limited to its
obligations relating to the collection of Prepayment Charges and the payment of
Master Servicer Prepayment Charge Amounts to the extent required in connection
with the waiver of any Prepayment Charge that is waived either (i) other than in
accordance with the standard set forth in Section 3.01(e) or (ii) as permitted
by meeting the standards described in clauses (i) and (ii)(B) of the first
sentence of Section 3.01(e), it being understood that no payment of any Master
Servicer Prepayment Charge Amount is required to be paid hereunder in connection
with the waiver of any Prepayment Charge that is waived as permitted by meeting
the standards described in clauses (i) and (ii)(A) of the first sentence of
Section 3.01(e)) or, if there has been a default in the fulfillment of any such
obligation, specifying each such default known to such officer and the nature
and status thereof including the steps being taken by the Master Servicer to
remedy such default.

                  Section 3.17 ANNUAL INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING
REPORT. (a) Within 120 days after December 31 of each year, commencing in
December 2000, the Master Servicer, at its expense, shall cause a nationally
recognized firm of independent certified public accountants to furnish to the
Master Servicer a report stating that (i) it has obtained a letter of
representation regarding certain matters from the management of the Master
Servicer which includes an assertion that the Master Servicer has complied with
certain minimum mortgage loan servicing standards identified in the Uniform
Single Attestation Program for Mortgage Bankers established by the Mortgage
Bankers Association of America with respect to the servicing of residential
mortgage loans during the most recently completed calendar year and (ii) on the
basis of an examination conducted by such firm in accordance with standards
established by the American Institute of Certified Public Accountants, such
representation is fairly stated in all material respects, subject to such
exceptions and other qualifications that may be appropriate. In rendering its
report such firm may rely, as to matters relating to the direct servicing of
residential mortgage loans by a Subservicer, upon comparable reports of firms of
independent certified public accountants rendered on the basis of examinations
conducted in accordance with the same standards (rendered within one year of
such report) with respect to such Subservicer. Immediately upon receipt of such
report, the Master Servicer shall furnish a copy of such report to the Trustee
and the Rating Agencies.

                  Section 3.18. OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS.
The Master Servicer may repurchase any Mortgage Loan that is 90 days or more
Delinquent for a price equal to the Repurchase Price. The Repurchase Price for
any Mortgage Loan purchased hereunder shall be deposited by the Master Servicer
in the Certificate Account and the Trustee, upon receipt of a Request for
Release and confirmation of such deposit from the Master Servicer in the form of
Exhibit D, shall release or cause to be released to the Master Servicer or its
designee, the related Mortgage File and shall execute and deliver such
instruments of transfer or assignment prepared by the Master Servicer or its
designee, in each case without recourse, representation or warranty, as shall be
necessary to vest in the Master Servicer or its designee ownership of such
Mortgage Loan released pursuant hereto.

                  Section 3.19. INFORMATION REQUIRED BY THE INTERNAL REVENUE
SERVICE GENERALLY AND REPORTS OF FORECLOSURES AND ABANDONMENTS OF MORTGAGED
PROPERTY. The Master Servicer shall prepare and deliver all federal and state
information reports when and as required by Section 6050J (reports of
foreclosures and abandonments), Section 6050H (reports relating to mortgage
interest received) and Section 6050P of the Code (reports relating to
cancellation of indebtedness).

                  Section 3.20. TITLE, MANAGEMENT AND DISPOSITION OF REO
                                PROPERTY.

                  (a) The deed or certificate of sale of any REO Property shall
be taken in the name of the Trustee, or its nominee, on behalf of the
Certificateholders. The Master Servicer, on behalf of the Trust Fund, shall
either sell any REO Property before the close of the third taxable year
following the year the Trust Fund acquires ownership of such REO Property for
purposes of Section 860G(a)(8) of the Code or request from the Internal Revenue
Service, more than 60 days before the day on which the three-year grace period
would otherwise expire an extension of the grace period, unless the Master
Servicer shall have delivered to the Trustee an Opinion of Counsel, addressed to
the Trustee and the Company, which Opinion of Counsel shall not be at the
expense of the Trust

                                       66

<PAGE>

Fund or the Trustee, to the effect that the holding by REMIC I of such REO
Property subsequent to such period after its acquisition will not result in the
imposition on REMIC I, REMIC II or REMIC III of taxes on "prohibited
transactions" thereof, as defined in Section 860F of the Code, or cause REMIC I,
REMIC II or REMIC III to fail to qualify as a REMIC under federal tax law at any
time that any Certificates are outstanding. The Master Servicer shall manage,
conserve, protect and operate each REO Property for the Certificateholders
solely for the purpose of its prompt disposition and sale in a manner which does
not cause such REO Property to fail to qualify as "foreclosure property" within
the meaning of Section 860G(a)(8) of the Code or result in the receipt by REMIC
I, REMIC II or REMIC III of any "income from non-permitted assets" within the
meaning of Section 860F(a)(2)(B) of the Code, or any "net income from
foreclosure property" which is subject to taxation under the REMIC Provisions.

                  (b) The Master Servicer shall segregate and hold all funds
collected and received in connection with the operation of any REO Property
separate and apart from its own funds and general assets and shall establish and
maintain with respect to REO Properties an account held in trust for the Trustee
for the benefit of the Certificateholders (the "REO Account"), which shall be an
Eligible Account. The Master Servicer shall be permitted to allow the
Certificate Account to serve as the REO Account, subject to separate ledgers or
subaccounts for each REO Property. The Master Servicer shall be entitled to
retain or withdraw any interest income paid on funds deposited or Eligible
Investments in the REO Account.

                  (c) The Master Servicer shall have full power and authority,
subject only to the specific requirements and prohibitions of this Agreement, to
do any and all things in connection with any REO Property as are consistent with
the manner in which the Master Servicer manages and operates similar property
owned by the Master Servicer or any of its Affiliates, all on such terms and for
such period as the Master Servicer deems to be in the best interests of
Certificateholders. In connection therewith, the Master Servicer shall deposit,
or cause to be deposited, on a daily basis in the REO Account all revenues
received by it with respect to an REO Property and shall withdraw therefrom
funds necessary for the proper operation, management and maintenance of such REO
Property including, without limitation:

                                    (i) all insurance premiums due and payable
                  in respect of such REO Property;

                                    (ii) all real estate taxes and assessments
                  in respect of such REO Property that may result in the
                  imposition of a lien thereon; and

                                    (iii) all costs and expenses necessary to
                  maintain such REO Property.

To the extent that amounts on deposit in the REO Account with respect to an REO
Property are insufficient for the purposes set forth in clauses (i) through
(iii) above with respect to such REO Property, the Master Servicer shall advance
from its own funds such amount as is necessary for such purposes, but only if
the Master Servicer would make such advances if the Master Servicer owned

                                       67

<PAGE>

the REO Property and if in the Master Servicer's reasonable good faith judgment,
the payment of such amounts will be recoverable from the rental or sale of the
REO Property.

                  Notwithstanding the foregoing, the Master Servicer shall not:

                  (i) permit the Trust Fund to enter into, renew or extend any
New Lease with respect to any REO Property, if the New Lease by its terms will
give rise to any income that does not constitute Rents from Real Property;

                  (ii) permit any amount to be received or accrued under any New
Lease other than amounts that will constitute Rents from Real Property;

                  (iii) authorize or permit any construction on any REO
Property, other than the completion of a building or other improvement thereon,
and then only if more than ten percent of the construction of such building or
other improvement was completed before default on the related Mortgage Loan
became imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

                  (iv) allow any Person to Directly Operate any REO Property on
any date more than 90 days after its date of acquisition by the Trust Fund;

unless, in any such case, the Master Servicer has obtained an Opinion of
Counsel, which Opinion of Counsel shall not be at the expense of the Trust Fund
or Trustee, provided to the Trustee, to the effect that such action will not
cause such REO Property to fail to qualify as "foreclosure property" within the
meaning of Section 860G(a)(8) of the Code at any time that it is held by REMIC
I, in which case the Master Servicer may take such actions as are specified in
such Opinion of Counsel.

                  The Master Servicer may contract with any Independent
Contractor for the operation and management of any REO Property, provided that:

                                    (i) the terms and conditions of any such
                  contract shall not be inconsistent herewith;

                                    (ii) any such contract shall require, or
                  shall be administered to require, that the Independent
                  Contractor pay all costs and expenses incurred in connection
                  with the operation and management of such REO Property,
                  including those listed above and remit all related revenues
                  (net of such costs and expenses) to the Master Servicer as
                  soon as practicable, but in no event later than thirty days
                  following the receipt thereof by such Independent Contractor;

                                    (iii) none of the provisions of this Section
                  3.20(c) relating to any such contract or to actions taken
                  through any such Independent Contractor shall be deemed to
                  relieve the Master Servicer of any of its duties and
                  obligations to the Trustee on behalf of the Certificateholders
                  with respect to the operation and management of any such REO
                  Property; and

                                       68

<PAGE>

                                    (iv) the Master Servicer shall be obligated
                  with respect thereto to the same extent as if it alone were
                  performing all duties and obligations in connection with the
                  operation and management of such REO Property.

The Master Servicer shall be entitled to enter into any agreement with any
Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Master Servicer by such
Independent Contractor, and nothing in this Agreement shall be deemed to limit
or modify such indemnification.

                  (d) In addition to the withdrawals permitted under Section
3.20(c), the Master Servicer may from time to time make withdrawals from the REO
Account for any REO Property: (i) to pay itself unpaid Servicing Fees in respect
of the related Mortgage Loan; and (ii) to reimburse itself for unreimbursed
Servicing Advances and Monthly Advances made in respect of such REO Property or
the related Mortgage Loan. On the Determination Date, the Master Servicer shall
withdraw from each REO Account maintained by it and deposit into the Certificate
Account in accordance with Section 3.06(b)(vi), for distribution on the related
Distribution Date in accordance with Section 4.01, the income from the related
REO Property received during the prior calendar month, net of any withdrawals
made pursuant to Section 3.20(c) or this Section 3.20(d).

                  (e) Subject to the time constraints set forth in Section
3.20(a), each REO Disposition shall be carried out by the Master Servicer at
such price and upon such terms and conditions as the Master Servicer shall deem
necessary or advisable, as shall be normal and usual in its general servicing
activities. Any REO Disposition shall be for cash only (unless changes in the
REMIC Provisions made subsequent to the Closing Date allow a sale for other
consideration).

                  Section 3.21. ADVANCE FACILITY.

                  (a) The Master Servicer is hereby authorized to enter into a
facility with any Person which provides that such Person (an "Advancing Person")
may fund Monthly Advances and/or Servicing Advances under this Agreement,
although no such facility shall reduce or otherwise affect the Master Servicer's
obligation to fund such Monthly Advances and/or Servicing Advances.
To the extent that an Advancing Person funds any Monthly Advance or any
Servicing Advance and provides the Trustee with notice acknowledged by the
Master Servicer that such Advancing Person is entitled to reimbursement, such
Advancing Person shall be entitled to receive reimbursement pursuant to this
Agreement for such amount to the extent provided in Section 3.21(b). Such notice
from the Advancing Person must specify the amount of the reimbursement and must
specify which Section of this Agreement permits the applicable Monthly Advance
or Servicing Advance to be reimbursed. The Trustee shall have no duty or
liability with respect to any calculation of any reimbursement to be paid to an
Advancing Person and shall be entitled to rely without independent investigation
on the Advancing Person's notice provided pursuant to this Section 3.21. An
Advancing Person whose obligations hereunder are limited to the funding of
Monthly Advances and/or Servicing Advances shall not be required to meet the
qualifications of a Subservicer pursuant to Section 3.02 hereof.

                  (b) If an Advancing Person is entitled to reimbursement for
any particular Monthly Advance or Servicing Advance, then the Master Servicer
shall not be permitted to reimburse itself therefor under Section 3.07(a)(iv) or
Section 3.07(a)(v), but instead the Master Servicer shall remit such amounts to
the Trustee (at the same time that the Master Servicer makes the monthly
remittance to the Trustee to the extent of amounts on deposit in the Certificate
Account on the related Determination Date). The Trustee is hereby authorized to
pay to an Advancing Person reimbursements for Monthly Advances and Servicing
Advances from the Distribution Account to the same extent the Master Servicer
would have been permitted to reimburse itself for such Monthly Advances and/or
Servicing Advances in accordance with Section 3.07(a)(iv) or Section 3.07(a)(v),
as the case may be, had the Master Servicer made such Monthly Advance or
Servicing Advance.

                  Section 3.22. USE OF FUNDS HELD FOR FUTURE DISTRIBUTION.

         The Master Servicer may, pursuant to Section 3.07(a)(iv), reimburse
itself for unreimbursed Monthly Advances and Servicing Advances from funds held
in the Certificate Account for future distribution that were not included in the
Available Distribution Amount for the preceding Distribution Date; provided,
however, that the Master Servicer is obligated to re-deposit such amounts into
the Certificate Account no later than the close of business on the Determination
Date immediately preceding the Distribution Date on which such funds are
required to be distributed pursuant to Section 4.01.

           Section 4.01. DISTRIBUTION ACCOUNT; INVESTMENT OF ACCOUNTS.

          (a) The Trustee shall establish and maintain a segregated account in
its name (the "Distribution Account"), which shall be an Eligible Account, into
which the Master Servicer shall deposit on or before each Determination Date by
wire transfer of immediately available funds an amount equal to that portion of
the Available Distribution Amount (calculated without regard to the references
in clause (2) of the definition thereof to amounts that may be withdrawn from
the Distribution Account) for the related Distribution Date then on deposit in
the Certificate Account, the amount of all Prepayment Charges on the Prepayment
Charge Schedule collected by the Master Servicer in connection with the
Principal Prepayment of any of the Mortgage Loans then on deposit in the
Certificate Account (other than any such Prepayment Charges received after the
related Due Period) and the amount of any funds reimbursable to an Advancing
Person pursuant to Section 3.21.

          (b) The Trustee shall, upon written request from the Master Servicer,
invest or cause the institution maintaining the Accounts to invest amounts in
the Accounts in Eligible Investments designated in the name of the Trustee,
which shall mature not later than the Business Day next preceding the
Distribution Date next following the date of such investment (except that (i)
any investment in the institution with which the Distribution Account is
maintained may mature on such Distribution Date and (ii) any other investment
may mature on such Distribution Date if the Trustee shall advance funds on such
Distribution Date to the Accounts in the amount payable on such investment on
such Distribution Date, pending receipt thereof to the extent necessary to make
distributions on the Certificates) and shall not be sold or disposed of prior to
maturity. All income and gain realized from any such investment shall be for the
benefit of the Master Servicer. The amount of any net losses incurred in respect
of any such investments shall be deposited in the related Account by the Master
Servicer.

          Section 4.02. DISTRIBUTIONS.

          (a) On each Distribution Date, the Trustee shall make, subject to the

provided in Section 9.01 respecting the final distribution) either in
immediately available funds (by wire transfer or otherwise) to the account of
such Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder has so notified the Master Servicer or the
Trustee, as the case may be, or, if such Certificateholder has not so notified
the Master Servicer or the Trustee by the Record Date, by check mailed to such
Certificateholder at the address of such Holder appearing in the Certificate
Register. Each Certificateholder's share of the distributions described below
shall be based on the aggregate of the Percentage Interests represented by
Certificates of the applicable Class held by such Holder.

          (b)(1)(A) On each Distribution Date, the following amounts, in the
following order of priority, shall be distributed by REMIC I to REMIC II on

               latest Prepayment Charge term as identified on the Mortgage Loan
               Schedule or any Distribution Date thereafter, then any such
               remaining amounts will be distributed FIRST, to the Holders of
               the Class P Certificates, until the Certificate Principal Balance
               thereof has been reduced to zero; and SECOND, to the Holders of
               the Class R- III Certificates.

          (c) On each Distribution Date, the Trustee shall withdraw any amounts
then on deposit in the Distribution Account that represent Prepayment Charges
collected by the Master Servicer in connection with the Principal Prepayment of
any of the Mortgage Loans or any Master Servicer Prepayment Charge Payment
Amount and shall distribute such amounts to the Holders of the Class P
Certificates. Such distributions shall not be applied to reduce the Certificate
Principal Balance of the Class P Certificates.

          (d) Each distribution with respect to a Book-Entry Certificate shall
be paid to the Depository, as Holder thereof, and the Depository shall be
responsible for crediting the amount of such distribution to the accounts of its
Depository Participants in accordance with its normal procedures. Each
Depository Participant shall be responsible for disbursing such distribution to
the Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. None of the Trustee, the
Certificate Registrar, the Company or the Master Servicer shall have any
responsibility therefor except as otherwise provided by this Agreement or
applicable law.

          (e) Except as otherwise provided in Section 9.01, if the Master
Servicer anticipates that a final distribution with respect to any Class of
Certificates will be made on the next Distribution Date, the Master Servicer
shall, no later than the Determination Date in the month of

                                       77

<PAGE>

such final distribution, notify the Trustee and the Trustee shall, no later than
two (2) Business Days after such Determination Date, mail on such date to each
Holder of such Class of Certificates a notice to the effect that: (i) the
Trustee anticipates that the final distribution with respect to such Class of
Certificates will be made on such Distribution Date but only upon presentation
and surrender of such Certificates at the office of the Trustee or as otherwise
specified therein, and (ii) no interest shall accrue on such Certificates from
and after the end of the prior calendar month. In the event that
Certificateholders required to surrender their Certificates pursuant to Section
9.01(c) do not surrender their Certificates for final cancellation, the Trustee
shall cause funds distributable with respect to such Certificates to be
withdrawn from the Distribution Account and credited to a separate escrow
account for the benefit of such Certificateholders as provided in Section
9.01(d).

          (f) Notwithstanding anything to the contrary herein, (i) in no event
shall the Certificate Principal Balance of a Class A Certificate or a
Subordinate Certificate be reduced more than once in respect of any particular
amount both (a) allocated to such Certificate in respect of Realized Losses
pursuant to Section 4.05 and (b) distributed to the Holder of such Certificate
in reduction of the Certificate Principal Balance thereof pursuant to this
Section 4.02 from Net Monthly Excess Cashflow and (ii) in no event shall the
Uncertificated Principal Balance of an Uncertificated REMIC I Regular Interest
be reduced more than once in respect of any particular amount both (a) allocated
to such Uncertificated REMIC I Regular Interest in respect of Realized Losses
pursuant to Section 4.05 and (b) distributed on such Uncertificated REMIC I
Regular Interest in reduction of the Uncertificated Principal Balance thereof
pursuant to this Section 4.02.

          Section 4.04. RESERVED.

          Section 4.05. ALLOCATION OF REALIZED LOSSES.

          (a) Prior to each Distribution Date, the Master Servicer shall
determine the total amount of Realized Losses, if any, that resulted from any
Cash Liquidation, Debt Service Reduction, Deficient Valuation or REO Disposition
that occurred during the related Due Period. The amount of each Realized Loss
shall be included in the report to the Trustee provided pursuant to Section
4.03(a).

          (b) All Realized Losses on the Mortgage Loans allocated to any
Uncertificated REMIC II Regular Interest pursuant to Section 4.05(c) on the
Mortgage Loans shall be allocated by the Trustee on each Distribution Date as
follows: first, to Net Monthly Excess Cashflow; second, to the Class CE
Certificates, until the Certificate Principal Balance thereof has been reduced
to zero; third, to the Class B Certificates, until the Certificate Principal
Balance thereof has been reduced to zero; fourth, to the Class M-2 Certificates,
until the Certificate Principal Balance thereof has been reduced to zero; and
fifth, to the Class M-1 Certificates, until the Certificate Principal Balance
thereof has been reduced to zero. All Realized Losses to be allocated to the
Certificate Principal Balances of all Classes on any Distribution Date shall be
so allocated after the actual distributions to be made on such date as provided
above. All references above to the Certificate Principal Balance of any Class of
Certificates shall be to the Certificate Principal Balance of such Class
immediately prior to the relevant Distribution Date, after reductions in respect
of actual distributions on such date but before reduction thereof by any
Realized Losses, in each case to be allocated to such Class of Certificates, on
such Distribution Date.

          Any allocation of Realized Losses to a Subordinate Certificate on any
Distribution Date shall be made by reducing the Certificate Principal Balance
thereof by the amount so allocated; any allocation of Realized Losses to a Class
CE Certificate shall be made FIRST, by reducing the amount otherwise payable in
respect thereof pursuant to Section 4.02(b)(4)(x) and SECOND, by reducing the
Certificate Principal Balance of such Certificate until it has been reduced to
zero. No allocations of any Realized Losses shall be made to the Certificate
Principal Balances of the Class A Certificates or the Class P Certificates.

          As used herein, an allocation of a Realized Loss on a "PRO RATA basis"
among two or more specified Classes of Certificates means an allocation on a PRO
RATA basis, among the various Classes so specified, to each such Class of
Certificates on the basis of their then outstanding Certificate Principal
Balances prior to giving effect to distributions to be made on such Distribution
Date. All Realized Losses and all other losses allocated to a Class of
Certificates hereunder will be

                                       81

<PAGE>

allocated among the Certificates of such Class in proportion to the Percentage
Interests evidenced thereby.

          (c) All Realized Losses on the Mortgage Loans shall be allocated by
the Trustee on each Distribution Date to the following Uncertificated REMIC I
Regular Interests in the specified percentages, as follows: first, to
Uncertificated Interest payable to Uncertificated REMIC I Regular Interest I-LT1
and Uncertificated REMIC I Regular Interest I-LT6 up to an aggregate amount
equal to the REMIC I Interest Loss Allocation Amount, 98% and 2%, respectively;
second, to the Uncertificated Principal Balances of Uncertificated REMIC I
Regular Interest I-LT1 and Uncertificated REMIC I Regular Interest I-LT6 up to
an aggregate amount equal to the REMIC I Principal Loss Allocation Amount, 98%
and 2%, respectively; third, to the Uncertificated Principal Balances of
Uncertificated REMIC I Regular Interest I-LT1, Uncertificated REMIC I Regular
Interest I-LT5 and Uncertificated REMIC I Regular Interest I-LT6, 98%, 1% and
1%, respectively, until the Uncertificated Principal Balance of Uncertificated
REMIC I Regular Interest I-LT5 has been reduced to zero; fourth to the
Uncertificated Principal Balances of Uncertificated REMIC I Regular Interest
I-LT1, Uncertificated REMIC I Regular Interest I-LT4 and Uncertificated REMIC I
Regular Interest I-LT6, 98%, 1% and 1%, respectively, until the Uncertificated
Principal Balance of Uncertificated REMIC I Regular Interest I-LT4 has been
reduced to zero; fifth to the Uncertificated Principal Balances of
Uncertificated REMIC I Regular Interest I-LT1, Uncertificated REMIC I Regular
Interest I-LT3 and Uncertificated REMIC I Regular Interest I-LT6, 98%, 1% and
1%, respectively, until the Uncertificated Principal Balance of Uncertificated
REMIC I Regular Interest I-LT3 has been reduced to zero.

          (d) All Realized Losses on the Uncertificated REMIC II Regular
Interests shall be allocated by the Trustee on each Distribution Date among the
Uncertificated REMIC II Regular Interests in the proportion that Realized Losses
are allocated to the related Uncertificated Corresponding Component.

          As used herein, an allocation of a Realized Loss on a "PRO RATA basis"
among the Uncertificated REMIC I Regular Interests (other than Uncertificated
REMIC I Regular Interest I- LTP) means an allocation on a PRO RATA basis among
the Uncertificated REMIC I Regular Interests (other than Uncertificated REMIC I
Regular Interest I-LTP) on the basis of their then outstanding Uncertificated
Principal Balances, in each case prior to giving effect to distributions to be
made on such Distribution Date.

          Section 4.06. 1934 ACT REPORTS.

          The Trustee shall prepare or cause to be prepared for filing and file
with the Securities and Exchange Commission (the "Commission"), with a copy to

Trust Fund and/or the Certificates required to be filed (other than the current
information on Form 8-K to be filed in connection with computational materials
and the initial Current Report on Form 8-K to be filed by the Company in

Trustee shall file with the Commission a Form 8-K with a copy of the Subsequent
Transfer Agreement, (iii) not later than March 30 of the first year commencing
after the date of the initial issuance of the Certificates, and each March 30
thereafter if such reporting obligation has not been suspended, the Trustee
shall file a Form 10-K in substance conforming to industry standard reporting
protocols permitted by the Commission for similar securities (or otherwise in
accordance with instructions provided by the Company), and (iv) not later than
January 30 of the first year for which the Company's reporting obligations have
been automatically suspended (which shall not be earlier than the first year
commencing after the date of the initial issuance of the Certificates) the
Trustee shall file a Form 15D, notifying the Commission of such suspension with
respect to the Trust Fund. The Company hereby grants to the Trustee a limited
power of attorney to execute and file each such report on behalf of the Company.
Such power of attorney shall continue until the earlier of (i) receipt by the
Trustee from the Company of written termination of such power of attorney and
(ii) the termination of the Trust Fund. Fees and expenses incurred by the
Trustee in connection with the foregoing shall be paid by the Trustee in
connection with the foregoing from the Trustee's fees and shall not be paid by
the Trust Fund. The Company, the Master Servicer and the Seller hereby agree to
promptly furnish to the Trustee, from time to time upon request, such further
information, reports and financial statements within their possession related to
this Agreement and the Mortgage Loans as the Trustee reasonably requires to
prepare and file all necessary reports with the Commission.

          Section 4.09 MONTHLY ADVANCES.

          If any Monthly Payment on a Mortgage Loan that was due on the
immediately preceding Due Date and delinquent on the Determination Date is
delinquent other than as a result of application of the Relief Act or Debt
Service Reduction, the Master Servicer (or the Trustee pursuant to Sections 7.01
and 7.02 hereof) on such Determination Date will deposit in the Certificate
Account an amount equal to the interest portion (net of the Servicing Fee) of
the scheduled Monthly Payment for such Mortgage Loan, except to the extent the
Master Servicer determines any such advance to be a Nonrecoverable Advance.
Subject to the foregoing and in the absence of such a determination, the Master
Servicer shall continue to make such advances through the date that the related
Mortgage Loan has, in the judgment of the Master Servicer, become a Liquidated
Mortgage Loan. If applicable, prior to each Determination Date, the Master
Servicer shall deliver an Officer's Certificate to the Trustee stating that the
Master Servicer elects not to make a Monthly Advance in a stated amount because
it would be a Nonrecoverable Advance or that a Monthly Advance previously made
has become a Nonrecoverable Advance. In lieu of making all or a portion of such
Monthly Advance from its own funds, the Master Servicer may (i) cause to be made
an appropriate entry in its records relating to the Certificate Account that any
amount held in the Certificate Account and not required for distribution on the
immediately succeeding Distribution Date has been used by the Master Servicer in
discharge of its obligation to make any such Monthly Advance and (ii) transfer
such funds from the Certificate Account to the Distribution Account. Any funds
so

applied and transferred shall be replaced by the Master Servicer by deposit in
the Certificate Account no later than the close of business on the Determination
Date immediately preceding the Distribution Date on which such funds are
required to be distributed pursuant to Section 4.01.

          Section 4.10 COMPENSATING INTEREST PAYMENTS.

          The Master Servicer shall deposit in the Certificate Account not later
than the Determination Date an amount equal to the Compensating Interest related
to such Determination Date. The Master Servicer shall not be entitled to any
reimbursement of any Compensating Interest payment.

          Section 4.11 PRE-FUNDING ACCOUNT.

          (a) No later than the Closing Date, the Trustee shall establish a
segregated trust account that is an Eligible Account, which shall be titled,
"Pre-Funding Account, Bank One, National Association, as trustee for the
registered holders of Mortgage Pass-Through Certificates, Series 2000-A". The
Trustee shall, promptly upon receipt, deposit in the Pre-Funding Account and
retain therein the Original Pre-Funded Amount remitted on the Closing Date to

Pre-Funding Account will be part of the Trust Fund.

          (b) Amounts on deposit in the Pre-Funding Account shall be withdrawn

          related Subsequent Transfer Agreement, shall withdraw from the
          Pre-Funding Account an amount equal to the Purchase Price for each
          Subsequent Mortgage Loan transferred and assigned to the Trustee on
          such Subsequent Transfer Date and pay such amount to the Seller upon
          satisfaction of the conditions with respect to such transfer and
          assignment set forth in Section 2.09 herein;

               (ii) [Reserved];

               (iii) The Trustee shall withdraw any amount not required to be
          deposited in the Pre-Funding Account or deposited therein in error;

               (iv) The Trustee shall clear and terminate the Pre-Funding
          Account upon the earliest to occur of (A) the Distribution Date
          following the end of the Pre- Funding Period, (B) the termination of
          this Agreement and (C) the termination of the Trust Fund, with any
          amounts remaining on deposit therein being deposited into the
          Distribution Account for payment to the Class A Certificateholders on

          Section 5.01. THE CERTIFICATES.

          (a) The Class A Certificates, the Subordinate Certificates, the Class
CE Certificates, the Class P Certificates and the Class R Certificates shall be
substantially in the forms set forth in Exhibits A-1, A-2, A-3, A-4 and B and
shall, on original issue, be executed and delivered by the Trustee to the
Certificate Registrar for authentication and delivery to or upon the order of
the Company upon receipt by the Trustee of the documents specified in Section
2.01. The Class A Certificates and the Subordinate Certificates shall be
initially evidenced by one or more certificates representing a fraction of the
initial Certificate Principal Balance for each Class and shall be issuable in
minimum dollar denominations of $10,000 and integral multiples of $1.00 in
excess thereof. The Class P Certificates shall be initially evidenced by one
more certificates representing a fraction of the initial Certificate Principal
Balance of such Class and shall be issuable in minimum dollar denominations of
$20 and integral multiples thereof. The Class CE Certificates shall be initially
evidenced by one or more certificates representing a fraction of the initial
Certificate Principal Balance of such Class and shall be issuable in minimum
dollar denominations of $10,000 and integral multiples of $1.00 in excess
thereof; provided, however, that one Class CE Certificate may be issued having
the remainder of the initial Certificate Principal Balance of such Class or to
an otherwise authorized denomination for such Class plus such remainder. The
Class R Certificates shall be issuable in minimum percentage interests of 20%
and integral multiples of 0.01% in excess thereof; PROVIDED, HOWEVER, that one
Class R-I Certificate, one Class R-II Certificate and one Class R-III
Certificate may be issued to the Trustee as "tax matters person" pursuant to
Section 10.01(c) in a minimum denomination representing a Percentage Interest of
not less than 0.01%.

          The Certificates shall be executed by manual or facsimile signature on
behalf of an authorized officer of the Trustee. Certificates bearing the manual
or facsimile signatures of individuals who were at any time the proper officers
of the Trustee shall bind the Trustee, notwithstanding that such individuals or
any of them have ceased to hold such offices prior to the authentication and
delivery of such Certificate or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
a certificate of authentication substantially in the form provided for herein
executed by the Certificate Registrar by manual signature, and such certificate
upon any Certificate shall be conclusive evidence, and the only evidence, that
such Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

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

                                       86

<PAGE>

as provided below, shall not be entitled to Definitive Certificates in respect
of such Ownership Interests. All transfers by Certificate Owners of their
respective Ownership Interests in the Book-Entry Certificates shall be made in
accordance with the procedures established by the Depository Participant or
brokerage firm representing such Certificate Owner. Each Depository Participant
shall transfer the Ownership Interests only in the Book-Entry Certificates of
Certificate Owners it represents or of brokerage firms for which it acts as
agent in accordance with the Depository's normal procedures.

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

          If (i)(A) the Trustee determines that the Depository is no longer
willing or able to properly discharge its responsibilities as Depository and (B)
the Trustee is unable to locate a qualified successor or (ii) the Trustee elects
to terminate the book-entry system through the Depository, or (iii) after the
occurrence of an Event of Default the Holders of the Book-Entry Certificates
having Percentage Interests aggregating at least a majority of the Certificate
Principal Balance of such Book-Entry Certificates advise the Depository in
writing that the continuation of a book-entry system through the Depository (or
a successor thereto) is no longer in the best interests of the Holders of the
Book-Entry Certificates, the Trustee shall notify all Certificate Owners,
through the Depository, of the occurrence of any such event and of the
availability of Definitive Certificates to Certificate Owners requesting the
same. Upon surrender to the Trustee of the Book-Entry Certificates by the
Depository, accompanied by registration instructions from the Depository for
registration of transfer, the Trustee shall issue the Definitive Certificates.
Neither the Company, the Master Servicer nor the Trustee shall be liable for any
actions taken by the Depository or its nominee, including, without limitation,
any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of
Definitive Certificates all references herein to obligations imposed upon or to
be performed by the Company in connection with the issuance of the Definitive
Certificates pursuant to this Section 5.01 shall be deemed to be imposed upon
and performed by the Trustee, and the Trustee and the Master Servicer shall
recognize the Holders of the Definitive Certificates as Certificateholders
hereunder.

          Section 5.02. REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.

          (a) The Trustee shall cause to be kept at one of the offices or
agencies to be appointed by the Trustee in accordance with the provisions of
Section 8.12 a Certificate Register in which, subject to such reasonable
regulations as it may prescribe, the Trustee shall provide for the registration
of Certificates and of transfers and exchanges of Certificates as herein
provided. The Trustee is initially appointed Certificate Registrar for the
purpose of registering Certificates and transfers and exchanges of Certificates
as herein provided. The Certificate Registrar, or the Trustee, shall provide the
Master Servicer with a certified list of Certificateholders as of each Record
Date prior to the related Determination Date.

          (b) Upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee maintained for such purpose pursuant to
Section 8.12 and, in the case of any Class R Certificate, upon satisfaction of
the conditions set forth below, the Trustee shall execute and the Certificate
Registrar shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Certificates of a like Class and
aggregate Percentage Interest.

          (c) At the option of the Certificateholders, Certificates may be
exchanged for other Certificates of authorized denominations of a like Class and
aggregate Percentage Interest, upon surrender of the Certificates to be
exchanged at any such office or agency. Whenever any Certificates are so
surrendered for exchange the Trustee shall execute and the Certificate Registrar
shall authenticate and deliver the Certificates of such Class which the
Certificateholder making the exchange is entitled to receive. Every Certificate
presented or surrendered for transfer or exchange shall (if so required by the
Trustee or the Certificate Registrar) be duly endorsed by, or be accompanied by
a written instrument of transfer in form satisfactory to the Trustee and the
Certificate Registrar duly executed by, the Holder thereof or his attorney duly
authorized in writing.

          (d) No transfer, sale, pledge or other disposition of a Class CE,
Class P or Class R Certificate shall be made unless such transfer, sale, pledge
or other disposition is exempt from the registration requirements of the
Securities Act of 1933, as amended (the "1933 Act"), and any applicable state
securities laws or is made in accordance with said Act. Except as otherwise
provided in this Section 5.02(d), in the event that a transfer of a Class CE,
Class P or Class R Certificate is to be made either (i)(A) the Trustee shall
require a written Opinion of Counsel acceptable to and in form and substance
satisfactory to the Trustee and the Company that such transfer may be made
pursuant to an exemption, describing the applicable exemption and the basis
therefor, from said Act or is being made pursuant to said Act, which Opinion of
Counsel shall not be an expense of the Trustee, the Company or the Master
Servicer; provided that such Opinion of Counsel will not be required in
connection with the initial transfer of any such Certificate by the Company or
any Affiliate thereof to an Affiliate of the Company and (B) the Trustee shall
require the transferee to execute a representation letter, substantially in the
form of Exhibit G-1 hereto, and the Trustee shall require the transferor to
execute a representation letter, substantially in the form of Exhibit H hereto,
each acceptable to and in form and substance satisfactory to the Company and the
Trustee certifying to the Company and the Trustee the facts surrounding such
transfer, which representation letters shall not be an expense of the Trustee,
the Company or the Master Servicer; provided, however, that such representation
letters will not be required in connection with any

                                       88

<PAGE>

transfer of any such Certificate by the Company or any Affiliate thereof to an
Affiliate of the Company, and the Trustee shall be entitled to conclusively rely
upon a representation (which, upon the request of the Trustee, shall be written
representation) from the Company of the status, of such transferee as an
Affiliate of the Company or (ii) the prospective transferee of such a
Certificate shall be required to provide the Trustee, the Company and the Master
Servicer with an investment letter substantially in the form of Exhibit G-1
attached hereto, which investment letter shall not be an expense of the Trustee,
the Company, or the Master Servicer, and which investment letter states that,
among other things, such transferee (A) is a "qualified institutional buyer" as
defined under Rule 144A, acting for its own account or the accounts of other
"qualified institutional buyers" as defined under Rule 144A, and (B) is aware
that the proposed transferor intends to rely on the exemption from registration
requirements under the 1933 Act provided by Rule 144A. The Holder of any such
Class CE, Class P or Class R Certificate desiring to effect any such transfer,
sale, pledge or other disposition shall, and does hereby agree to, indemnify the
Trustee, the Company, the Master Servicer and the Certificate Registrar against
any liability that may result if the transfer, sale, pledge or other disposition
is not so exempt or is not made in accordance with such federal and state laws
and this Agreement.

          (e) Transfers of Subordinate Certificates, Class CE Certificates,
Class P Certificates or Class R Certificates to a Plan, to a trustee or other
person acting on behalf of any Plan, or to any other person using the assets of
any Plan will not be registered by the Trustee unless the transferee provides
the Company, the Trustee and the Master Servicer with an opinion of counsel
satisfactory to the Company, the Trustee and the Master Servicer, which opinion
will not be at the expense of the Company, the Trustee or the Master Servicer,
that the purchase of such Certificates by or on behalf of such Plan is
permissible under applicable law, will not constitute or result in a non-exempt
prohibited transaction under ERISA or Section 4975 of the Code and will not
subject the Company, the Trustee or the Master Servicer to any obligation in
addition to those undertaken in this Agreement. In the case of the Subordinate
Certificates, in lieu of such opinion of counsel, the transferee may provide a
certification (which in the case of the Subordinate Certificates sold in book-
entry form, the transferee will be deemed to have made the representations in
such certification) in the form of Exhibit G-2 to this Agreement (or other form
acceptable to the Company, the Trustee and the Master Servicer), which the
Trustee may rely upon without further inquiry or investigation. Neither an
Opinion of Counsel nor any certification will be required in connection with the
initial transfer of any such Certificate by the Company to an Affiliate of the
Company (in which case, the Company or any Affiliate thereof shall be deemed to
have represented that such Affiliate is not a Plan or a Person investing Plan
Assets) and the Trustee shall be entitled to conclusively rely upon a
representation (which, upon the request of the Trustee, shall be a written
representation) from the Company of the status of such transferee as an
Affiliate of the Company.

          If any Subordinate Certificate, Class CE Certificate, Class P
Certificate or Class R Certificate or any interest therein is acquired or held
in violation of the provisions of the preceding paragraph, the next preceding
permitted beneficial owner will be treated as the beneficial owner of that
Certificate retroactive to the date of transfer to the purported beneficial
owner. Any purported beneficial owner whose acquisition or holding of any such
Certificate or interest therein was effected in violation of the provisions of
the preceding paragraph shall indemnify and hold harmless the Company, the
Master Servicer, the Trustee and the Trust Fund from and against any and all

                                       89

<PAGE>

liabilities, claims, costs or expenses incurred by those parties as a result of
that acquisition or holding.

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

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

                    (B) In connection with any proposed Transfer of any
          Ownership Interest in a Class R Certificate, the Trustee shall require
          delivery to it, and shall not register the Transfer of any Class R
          Certificate until its receipt of, (I) an affidavit and agreement (a
          "Transfer Affidavit and Agreement," in the form attached hereto as
          Exhibit F-1) from the proposed Transferee, in form and substance
          satisfactory to the Master Servicer, representing and warranting,
          among other things, that it is a Permitted Transferee, that it is not
          acquiring its Ownership Interest in the Class R Certificate that is
          the subject of the proposed Transfer as a nominee, trustee or agent
          for any Person who is not a Permitted Transferee, that for so long as
          it retains its Ownership Interest in a Class R Certificate, it will
          endeavor to remain a Permitted Transferee, and that it has reviewed
          the provisions of this Section 5.02(f) and agrees to be bound by them,
          and (II) a certificate, in the form attached hereto as Exhibit F-2,
          from the Holder wishing to transfer the Class R Certificate, in form
          and substance satisfactory to the Master Servicer, representing and
          warranting, among other things, that no purpose of the proposed
          Transfer is to impede the assessment or collection of tax.

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

                    (D) Each Person holding or acquiring any Ownership Interest
          in a Class R Certificate shall agree (x) to require a Transfer
          Affidavit and Agreement from any other Person to whom such Person
          attempts to transfer its Ownership Interest in a Class R Certificate
          and (y) not to transfer its Ownership Interest unless it provides a
          certificate to the Trustee in the form attached hereto as Exhibit F-2.

                                       90

<PAGE>

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

               (ii) The Trustee will register the Transfer of any Class R
     Certificate only if it shall have received the Transfer Affidavit and
     Agreement, a certificate of the Holder requesting such transfer in the form
     attached hereto as Exhibit F-2 and all of such other documents as shall
     have been reasonably required by the Trustee as a condition to such
     registration. Transfers of the Class R Certificates to Non-United States
     Persons and Disqualified Organizations (as defined in Section 860E(e)(5) of
     the Code) are prohibited.

               (iii) (A) If any Disqualified Organization shall become a holder
     of a Class R Certificate, then the last preceding Permitted Transferee
     shall be restored, to the extent permitted by law, to all rights and
     obligations as Holder thereof retroactive to the date of registration of
     such Transfer of such Class R Certificate. If a Non-United States Person
     shall become a holder of a Class R Certificate, then the last preceding
     United States Person shall be restored, to the extent permitted by law, to
     all rights and obligations as Holder thereof retroactive to the date of
     registration of such Transfer of such Class R Certificate. If a transfer of
     a Class R Certificate is disregarded pursuant to the provisions of Treasury
     Regulation Section 1.860E-1 or Section 1.860G-3, then the last preceding
     Permitted Transferee shall be restored, to the extent permitted by law, to
     all rights and obligations as Holder thereof retroactive to the date of
     registration of such Transfer of such Class R Certificate. The Trustee
     shall be under no liability to any Person for any registration of Transfer
     of a Class R Certificate that is in fact not permitted by this Section
     5.02(f) or for making any payments due on such Certificate to the holder
     thereof or for taking any other action with respect to such holder under
     the provisions of this Agreement.

                    (B) If any purported Transferee shall become a Holder of a
          Class R Certificate in violation of the restrictions in this Section
          5.02(f) and to the extent that the retroactive restoration of the
          rights of the Holder of such Class R Certificate as described in
          clause (iii)(A) above shall be invalid, illegal or unenforceable, then
          the Master Servicer shall have the right, without notice to the holder
          or any prior holder of such Class R Certificate, to sell such Class R
          Certificate to a purchaser selected by the Master Servicer on such
          terms as the Master Servicer may choose. Such purported Transferee
          shall promptly endorse and deliver each Class R Certificate in
          accordance with the instructions of the Master Servicer. Such
          purchaser may be the Master Servicer itself or any Affiliate of the
          Master Servicer. The proceeds of such sale, net of the commissions
          (which may include commissions payable to the Master Servicer or its
          Affiliates), expenses and taxes due, if any, will be remitted by the
          Master Servicer to such purported Transferee. The terms and conditions
          of any sale under this clause (iii)(B) shall be determined in the sole

                                       91

<PAGE>

          discretion of the Master Servicer, and the Master Servicer shall not
          be liable to any Person having an Ownership Interest in a Class R
          Certificate as a result of its exercise of such discretion.

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

               (v) The provisions of this Section 5.02(f) set forth prior to
     this clause (v) may be modified, added to or eliminated, provided that
     there shall have been delivered to the Trustee the following:

                    (A) written notification from each Rating Agency to the
          effect that the modification, addition to or elimination of such
          provisions will not cause such Rating Agency to downgrade its
          then-current ratings, if any, of any Class of the Class A Certificates
          or Subordinate Certificates below the lower of the then-current rating
          or the rating assigned to such Certificates as of the Closing Date by
          such Rating Agency; and

                    (B) subject to Section 10.01(f), a certificate of the Master
          Servicer stating that the Master Servicer has received an Opinion of
          Counsel, in form and substance satisfactory to the Master Servicer, to
          the effect that such modification, addition to or absence of such
          provisions will not cause REMIC I, REMIC II or REMIC III to cease to
          qualify as a REMIC and will not cause (x) the Trust Fund to be subject
          to an entity-level tax caused by the Transfer of any Class R
          Certificate to a Person that is a Disqualified Organization or (y) a
          Certificateholder or another Person to be subject to a REMIC-related
          tax caused by the Transfer of a Class R Certificate to a Person that
          is not a Permitted Transferee.

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

          (h) All Certificates surrendered for transfer and exchange shall be
destroyed by the Certificate Registrar.

<PAGE>

          Section 5.03. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

          If (i) any mutilated Certificate is surrendered to the Certificate
Registrar, or the Trustee and the Certificate Registrar receive evidence to
their satisfaction of the destruction, loss or theft of any Certificate, and
(ii) there is delivered to the Trustee and the Certificate Registrar such
security or indemnity as may be required by them to save each of them harmless,
then, in the absence of notice to the Trustee or the Certificate Registrar that
such Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute and the Certificate Registrar shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like tenor, Class and Percentage Interest but
bearing a number not contemporaneously outstanding. Upon the issuance of any new
Certificate under this Section, the Trustee may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the
Trustee and the Certificate Registrar) connected therewith. Any duplicate
Certificate issued pursuant to this Section shall constitute complete and
indefeasible evidence of ownership in the Trust Fund, as if originally issued,
whether or not the lost, stolen or destroyed Certificate shall be found at any
time.

          Section 5.04. PERSONS DEEMED OWNERS.

          Prior to due presentation of a Certificate for registration of
transfer, the Company, the Master Servicer, the Trustee, the Certificate
Registrar and any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar may treat the Person in whose name any Certificate is
registered as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 4.02 and for all other purposes whatsoever,
and neither the Company, the Master Servicer, the Trustee, the Certificate
Registrar nor any agent of the Company, the Master Servicer, the Trustee or the
Certificate Registrar shall be affected by notice to the contrary except as
provided in Section 5.02(f).

          Section 5.05. APPOINTMENT OF PAYING AGENT.

          The Trustee may appoint a Paying Agent for the purpose of making
distributions to the Certificateholders pursuant to Section 4.02. In the event
of any such appointment, on or prior to each Distribution Date the Master
Servicer on behalf of the Trustee shall deposit or cause to be deposited with
the Paying Agent a sum sufficient to make the payments to the Certificateholders
in the amounts and in the manner provided for in Section 4.02, such sum to be
held in trust for the benefit of the Certificateholders.

          The Trustee shall cause each Paying Agent to execute and deliver to
the Trustee an instrument in which such Paying Agent shall agree with the
Trustee that such Paying Agent will hold all sums held by it for the payment to
the Certificateholders in trust for the benefit of the Certificateholders
entitled thereto until such sums shall be paid to such Certificateholders. Any
sums so held by such Paying Agent shall be held only in Eligible Accounts to the
extent such sums are not distributed to the Certificateholders on the date of
receipt by such Paying Agent.

                       THE COMPANY AND THE MASTER SERVICER

          Section 6.01. RESPECTIVE LIABILITIES OF THE COMPANY AND THE MASTER
                        SERVICER.

          The Company and the Master Servicer shall each be liable in accordance
herewith only to the extent of the obligations specifically and respectively
imposed upon and undertaken by the Company and the Master Servicer herein. By
way of illustration and not limitation, the Company is not liable for the
servicing and administration of the Mortgage Loans, nor is it obligated by
Sections 7.01 or 10.01 to assume any obligations of the Master Servicer or to
appoint a designee to assume such obligations, nor is it liable for any other
obligation hereunder that it may, but is not obligated to, assume unless it
elects to assume such obligation in accordance herewith.

          Section 6.02. MERGER OR CONSOLIDATION OF THE COMPANY OR THE MASTER
                        SERVICER.

          (a) The Company and the Master Servicer will each keep in full effect
its existence, rights and franchises as a corporation under the laws of the
state of its incorporation, 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, the Certificates or any of the Mortgage Loans
and to perform its respective duties under this Agreement.

          (b) Any Person into which the Company or the Master Servicer may be
merged or consolidated, or any corporation resulting from any merger or
consolidation to which the Company or the Master Servicer shall be a party, or
any Person succeeding to the business of the Company or the Master Servicer,
shall be the successor of the Company or the Master Servicer, as the case may
be, hereunder, without the execution or filing of any paper or any further act
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding; provided, such successor must satisfy the requirements of
Section 7.02 herein.

          Section 6.03. LIMITATION ON LIABILITY OF THE COMPANY, THE MASTER
                        SERVICER AND OTHERS.

          Neither the Company, the Master Servicer nor any of the directors,
officers, employees or agents of the Company or the Master Servicer shall be
under any liability to the Trust Fund, the Trustee or the Certificateholders for
any action taken or for refraining from the taking of any action in good faith
pursuant to this Agreement; PROVIDED, HOWEVER, that this provision shall not
protect the Company, the Master Servicer or any such Person against any
liability which would otherwise be imposed by reason of willful misfeasance, bad
faith or gross negligence in the performance of duties hereunder or by reason of
reckless disregard of obligations and duties hereunder. The Company, the Master
Servicer and any director, officer, employee or agent of the Company or the
Master Servicer may rely in good faith on any document of any kind PRIMA FACIE
properly executed and submitted by any Person respecting any matters arising
hereunder. The Company, the Master Servicer and any director, officer, employee
or agent of the Company or the

                                       94

<PAGE>

Master Servicer shall be indemnified by the Trust Fund and held harmless against
any loss, liability or expense incurred in connection with any legal action
relating to this Agreement or the Certificates, including any amount paid to the
Trustee pursuant to Section 8.05, other than any loss, liability or expense
related to any specific Mortgage Loan or Mortgage Loans (except as any such
loss, liability or expense shall be otherwise reimbursable pursuant to this
Agreement) and any loss, liability or expense incurred by reason of willful
misfeasance, bad faith or gross negligence in the performance of duties
hereunder or by reason of reckless disregard of obligations and duties
hereunder.

          Neither the Company nor the Master Servicer shall be under any
obligation to appear in, prosecute or defend any legal action which is not
incidental to its respective duties under this Agreement and which in its
opinion may involve it in any expense or liability; PROVIDED, HOWEVER, that the
Company or the Master Servicer may in its discretion undertake any such action,
proceeding, hearing or examination that it may deem necessary or desirable in
respect of this Agreement or the Mortgage Loans, and the rights and duties of
the parties hereto and the interests of the Certificateholders hereunder. In
such event, the reasonable legal expenses and costs of such action and any
liability resulting therefrom shall be expenses, costs and liabilities of the
Trust Fund, and the Company and the Master Servicer shall be entitled to be
reimbursed therefor. The Master Servicer's and the Company's right to indemnity
or reimbursement pursuant to this Section 6.03 shall survive any resignation or
termination of the Master Servicer or the Company pursuant to Section 6.04 or
7.01 with respect to any losses, expenses, costs or liabilities arising prior to
such resignation or termination (or arising from events that occurred prior to
such resignation or termination) out of amounts attributable to the Mortgage
Loans on deposit in the Certificate Account as provided by Section 3.07.

          Section 6.04. COMPANY AND MASTER SERVICER NOT TO RESIGN.

          Subject to the provisions of Section 6.02, neither the Master Servicer
nor the Company shall resign from its respective obligations and duties hereby
imposed on it except (i) upon determination that the performance of its
obligations or duties hereunder are no longer permissible under applicable law
which cannot be cured without unreasonable cost, as evidenced by an Opinion of
Counsel to such effect delivered to the Trustee or (ii) with respect to the
Master Servicer, upon satisfaction of the following conditions: (a) the Master
Servicer has proposed a successor servicer to the Trustee in writing and such
proposed successor servicer is, in the reasonable judgment of the Trustee,
acceptable; and (b) each Rating Agency shall have confirmed in writing that the
proposed appointment of such successor servicer as Master Servicer hereunder
will not result in the qualification, reduction or withdrawal of the then
current rating of the Certificates; PROVIDED, HOWEVER, that no such resignation
by the Master Servicer shall become effective until such successor servicer or,
in the case of (i) above, the Trustee, shall have assumed the Master Servicer's
responsibilities and obligations hereunder or the Trustee shall have designated
a successor servicer in accordance with Section 7.02. Any such resignation shall
not relieve the Master Servicer of responsibility for any of the obligations
specified in Sections 7.01 and 7.02 as obligations that survive the resignation
or termination of the Master Servicer.

                                     DEFAULT

          Section 7.01. EVENTS OF DEFAULT.

          Event of Default, wherever used herein, means the occurrence and
continuance of any one of the following events:

            (i) any failure by the Master Servicer to deposit in the Certificate
     Account or Distribution Account any deposit required to be made under the
     terms of this Agreement, including any Monthly Advances and Compensating
     Interest, which failure continues unremedied for a period of five Business
     Days after the date upon which written notice of such failure shall have
     been given to the Master Servicer by the Trustee, or to the Master Servicer
     and the Trustee by Certificateholders holding Certificates evidencing at
     least 25% of the aggregate Voting Rights; or

            (ii) any failure on the part of the Master Servicer duly to observe
     or perform in any material respect any other of its covenants or agreements
     of the Master Servicer set forth in this Agreement, which failure, in each
     case, materially and adversely affects the interests of Certificateholders
     and which continues unremedied for a period of 30 days after the date on
     which written notice of such failure, requiring the same to be remedied and
     stating that such notice is a notice of default, shall have been given to
     the Master Servicer by the Trustee, or to the Master Servicer and the
     Trustee by Certificateholders holding Certificates evidencing at least 25%
     of the aggregate Voting Rights; or

            (iii) the entry against the Master Servicer of a decree or order of
     a court or agency or supervisory authority having jurisdiction in the
     premises for the appointment of a trustee, conservator, receiver or
     liquidator in any insolvency, conservatorship, receivership, readjustment
     of debt, marshalling of assets and liabilities or similar proceedings, or
     for the winding-up or liquidation of its affairs and the continuance of any
     such decree or order unstayed for a period of 90 consecutive days; or

            (iv) the Master Servicer shall commence a voluntary case in
     bankruptcy, consent to the appointment of a conservator, receiver,
     liquidator or similar person in any insolvency, readjustment of debt,
     marshalling of assets and liabilities or similar proceedings of or relating
     to the Master Servicer or of or relating to all or substantially all of its
     property; or the Master Servicer shall admit in writing its inability to
     pay its debts generally as they become due, file a petition to take
     advantage of any applicable insolvency or reorganization statute, make an
     assignment for the benefit of its creditors or voluntarily suspend payment
     of its obligations; or

            (v) so long as the Seller is the Master Servicer and subject to the
     limitations set forth in the Mortgage Loan Purchase Agreement, any failure
     of the Seller to repurchase or

                                       96

<PAGE>

     substitute Qualified Substitute Mortgage Loans for Deleted Mortgage Loans
     as required pursuant to the Mortgage Loan Purchase Agreement and this
     Agreement; or

            (vi) a Servicer Termination Event has occurred and is continuing.

So long as an Event of Default shall not have been remedied by the Master
Servicer, either the Trustee or the holders of at least 51% of the aggregate
Voting Rights, by notice then given in writing to the Master Servicer (and to
the Trustee, as applicable) may, by notice to the Master Servicer, terminate all
of the rights and obligations of the Master Servicer as servicer under this
Agreement other than the Master Servicer's right to receive servicing
compensation and reimbursement for expenses for servicing the Mortgage Loans
hereunder during any period prior to the date of such termination and the
Trustee may exercise any and all other remedies available at law or equity. Any
such notice to the Master Servicer shall also be given to each Rating Agency. On
or after the receipt by the Master Servicer of such written notice, all
authority and power of the Master Servicer under this Agreement shall pass to
and be vested in the Trustee, and, without limitation, the Trustee is hereby
authorized and empowered to execute and deliver, on behalf of the Master
Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement of each Mortgage Loan and related
documents, or otherwise. The Master Servicer agrees to cooperate with the
Trustee in effecting the termination of the responsibilities and rights of the
Master Servicer hereunder, including, without limitation, the transfer to the
Trustee for the administration by it of all cash amounts relating to the
Mortgage Loans that shall at the time be held by the Master Servicer and
required to be deposited by it in the Certificate Account, or that have been
deposited by the Master Servicer in the Certificate Account or thereafter
received by the Master Servicer with respect to the Mortgage Loans.

          Notwithstanding any termination of the activities of the Master
Servicer hereunder, the Master Servicer shall be entitled to receive all amounts
payable to the Master Servicer hereunder the entitlement to which arose prior to
the termination of its activities hereunder. No termination of the Master
Servicer shall affect any obligation of the Seller.

          Notwithstanding the foregoing, a delay in or failure of performance
under Section 7.01(i) or Section 7.01(ii) after the applicable grace periods
specified in such Sections shall not constitute an Event of Default if such
delay or failure could not be prevented by the exercise of reasonable diligence
by the Master Servicer and such delay or failure was caused by an act of God,
acts of declared or undeclared war, public disorder, rebellion or sabotage,
epidemics, landslides, lightning, fire, hurricanes, earthquakes, floods or
similar causes. The preceding sentence shall not relieve the Master Servicer
from using reasonable efforts to perform its respective obligations in a timely
manner in accordance with the terms of this Agreement and the Master Servicer
shall provide the Trustee and the Certificateholders with notice of such failure
or delay by it, together with a description of its efforts to so perform its
obligations. The Master Servicer shall immediately notify the Trustee in writing
of any Event of Default.

          Section 7.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) On and
after the time the Master Servicer receives a notice of termination pursuant to
Section 7.01 or sends a notice

                                       97

<PAGE>

pursuant to Section 6.04, the Trustee shall be the successor in all respects to
the Master Servicer in its capacity as servicer under this Agreement and shall
be subject to all the responsibilities, duties and liabilities relating thereto
placed on the Master Servicer by the terms and provisions hereof, including but
not limited to the provisions of Article III. Nothing in this Agreement shall be
con strued to permit or require the Trustee to (i) succeed to the
responsibilities, duties and liabilities of the Master Servicer in its capacity
as the Seller under the Mortgage Loan Purchase Agreement or under this
Agreement, (ii) be responsible or accountable for any act or omission of the
Master Servicer prior to the issuance of a notice of termination hereunder,
(iii) require or obligate the Trustee, in its capacity as successor Master
Servicer, to purchase, repurchase or substitute any Mortgage Loan, (iv) fund any
losses on any Eligible Investment directed by any other Master Servicer, or (v)
be responsible for the representations and warranties of the Master Servicer;
PROVIDED, HOWEVER, that the Trustee, as successor Master Servicer, shall be
required to make any Monthly Advances to the extent that the Master Servicer
failed to make such Monthly Advances. As compensation therefor, the Trustee
shall be entitled to such compensation as the Master Servicer would have been
entitled to hereunder if no such notice of termination had been given (other
than compensation accruing prior to the notice of termination). Notwithstanding
the above, (i) if the Trustee is unwilling to act as successor Master Servicer,
or (ii) if the Trustee is legally unable so to act, the Trustee on behalf of the
Certificateholders may (in the situation described in clause (i)) or shall (in
the situation described in clause (ii)) appoint or petition a court of competent
jurisdiction to appoint any established housing and home finance institution,
bank or other mortgage loan servicer having a net worth of not less than
$15,000,000 as the successor to the Master Servicer hereunder in the assumption
of all or any part of the responsibilities, duties or liabilities of the Master
Servicer hereunder; PROVIDED, that each Rating Agency shall have confirmed in
writing that the appointment of any such successor Master Servicer will not
result in the qualification, reduction or withdrawal of the ratings assigned to
the Certificates by the Rating Agencies. Pending appointment of a successor to
the Master Servicer hereunder, unless the Trustee is prohibited by law from so
acting, the Trustee shall act in such capacity as hereinabove provided. In
connection with such appointment and assumption, the successor shall be entitled
to receive compensation in an amount equal to the compensation which the Master
Servicer would otherwise have received pur suant to Section 3.15 (or such lesser
compensation as the Trustee and such successor shall agree). The appointment of
a successor Master Servicer shall not affect any liability of the predecessor
Master Servicer which may have arisen under this Agreement prior to its
termination as Master Servicer, nor shall any successor Master Servicer be
liable for any acts or omissions of the predecessor Master Servicer or for any
breach by such Master Servicer of any of its representations or warranties
contained herein. The Trustee and such successor shall take such action,
consistent with this Agreement, as shall be necessary to effectuate any such
succession.

          (b) Any successor Master Servicer, including the Trustee on behalf of
the Certificateholders, shall not be deemed to be in default or to have breached
its duties hereunder if the predecessor Master Servicer shall fail to deliver
any required deposit to the Certificate Account or otherwise cooperate with any
required servicing transfer or succession hereunder.

          Section 7.03 WAIVER OF EVENTS OF DEFAULT. The Trustee shall transmit
by mail to all Certificateholders, promptly after the occurrence of any Event of
Default known to the Trustee, unless such Event of Default shall have been
cured, notice of each such Event of Default hereunder

                                       98

<PAGE>

known to the Trustee. The Holders of at least 66% of the aggregate Voting Rights
may waive any default by the Master Servicer in the performance of its
obligations hereunder and the consequences thereof, except a default under
Section 7.01(i), which shall require the waiver of all Certificateholders
affected by such Event of Default; provided, that no waiver shall reduce in any
manner the amount of, or delay the timing of, payments received on Mortgage
Loans which are required to be distributed to, or otherwise materially adversely
affect, any non-consenting Certificateholder. Upon any such waiver of a past
default, such default shall be deemed to cease to exist, and any Event of
Default arising therefrom shall be deemed to have been timely remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived. The Master Servicer shall give notice of any such waiver to
the Rating Agencies.

                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

          Section 8.01. DUTIES OF TRUSTEE.

          (a) The Trustee, prior to the occurrence of an Event of Default and
after the curing or waiver of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Agreement. In case an Event of Default has occurred (which has not
been cured or waived), the Trustee shall exercise such of the rights and powers
vested in it by this Agreement, and use the same degree of care and skill in
their exercise as a prudent investor would exercise or use under the
circumstances in the conduct of such investor's own affairs, unless the Trustee
is acting as Master Servicer pursuant to Section 7.02, in which case it shall
use the same degree of care and skill as is required of the Master Servicer
under this Agreement.

          (b) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement.

          The Trustee shall forward or cause to be forwarded in a timely fashion
the notices, reports and statements required to be forwarded by the Trustee
pursuant to Sections 4.03, 4.06, 7.03 and 10.01. The Trustee shall furnish in a
timely fashion to the Master Servicer such information as the Master Servicer
may reasonably request from time to time for the Master Servicer to fulfill its
duties as set forth in this Agreement. The Trustee covenants and agrees that it
shall perform its obligations hereunder in a manner so as to maintain the status
of each of REMIC I, REMIC II and REMIC III as REMICs under the REMIC Provisions
and (subject to Section 10.01(f)) to prevent the imposition of any federal,
state or local income, prohibited transaction, contribution or other tax on any
of REMIC I, REMIC II or REMIC III to the extent that maintaining such status and
avoiding such taxes are reasonably within the control of the Trustee and are
reasonably within the scope of its duties under this Agreement.

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

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

                                       100

<PAGE>

     the Trustee by the Company or the Master Servicer and which on their face,
     do not contradict the requirements of this Agreement;

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

                    (iii) The Trustee shall not be personally liable with
     respect to any action taken, suffered or omitted to be taken by it in good
     faith in accordance with the direction of the Certificateholders holding
     Certificates of any Class affected thereby which evidence, as to such
     Class, Percentage Interests aggregating not less than 51% as 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;

                    (iv) The Trustee shall not be charged with knowledge of any
     default (other than a default in payment to the Trustee) specified in
     clauses (i) and (ii) of Section 7.01 or an Event of Default under clauses
     (iii), (iv), (v) and (vi) of Section 7.01 unless a Responsible Officer of
     the Trustee assigned to and working in the Corporate Trust Office obtains
     actual knowledge of such failure or event or the Trustee receives written
     notice of such failure or event at its Corporate Trust Office from the
     Master Servicer, the Company or any Certificateholder; and

                    (v) Except to the extent provided in Section 7.02, no
     provision in this Agreement shall require the Trustee to expend or risk its
     own funds or otherwise incur any personal financial liability in the
     performance of any of its duties as Trustee hereunder, or in the exercise
     of any of its rights or powers, if the Trustee shall have reasonable
     grounds for believing that repayment of funds or adequate indemnity against
     such risk or liability is not reasonably assured to it.

          The Trustee shall not be required to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers (other than
expenses, disbursements and advances incurred or made by the Trustee, including
the compensation and the expenses of its employees, agents and counsel, in the
ordinary course of the Trustee's performance in accordance with the provisions
of this Agreement), if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it, and none of the provisions contained in this
Agreement shall in any event require the Trustee to perform, or be responsible
for the manner of per formance of, any of the obligations of the Master Servicer
under this Agreement, except during such time, if any, as the Trustee shall be
the successor to, and be vested with the rights, duties, powers and privileges
of, the Master Servicer in accordance with the terms of this Agreement.

          Subject to the other provisions of this Agreement and without limiting
the generality of this Section, the Trustee shall have no duty (A) to see to the
payment or discharge of any tax, assessment, or other governmental charge or any
lien or encumbrance of any kind owing with respect to, assessed or levied
against, any part of the Trust Fund from funds available in the Certificate

Account or (B) to confirm or verify the contents of any reports or certificates
of the Master Servicer delivered to the Trustee pursuant to this Agreement
believed by the Trustee to be genuine and to have been signed or presented by
the proper party or parties.

          Section 8.02. CERTAIN MATTERS AFFECTING THE TRUSTEE.

          (a)  Except as otherwise provided in Section 8.01:

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

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

               (iii) The Trustee shall be under no obligation to exercise any of
     the trusts or powers vested in it by this Agreement or to institute,
     conduct or defend any litigation hereunder or in relation hereto at the
     request, order or direction of any of the Certificateholders pursuant to
     the provisions of this Agreement, unless such Certificateholders shall have
     offered to the Trustee reasonable security or indemnity against the costs,
     expenses and liabilities which may be incurred therein or thereby has given
     its consent; nothing contained herein shall, however, relieve the Trustee
     of the obligation, upon the occurrence of an Event of Default (which has
     not been cured or waived), to exercise such of the rights and powers vested
     in it by this Agreement, and to use the same degree of care and skill in
     their exercise as a prudent investor would exercise or use under the
     circumstances in the conduct of such investor's own affairs;

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

               (v) Prior to the occurrence of an Event of Default hereunder and
     after the curing or waiver of all Events of Default which may have
     occurred, the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, consent, order, approval,
     bond or other paper or document, unless requested in writing so to do by
     the Holders of Certificates of any Class evidencing, as to such Class,
     Percentage Interests, aggregating not less than 51%; PROVIDED, HOWEVER,
     that if the payment within a reasonable time to the Trustee of the costs,
     expenses or liabilities likely to be incurred by it in the making of such
     investigation is, in the opinion of the Trustee, not reasonably assured to
     the Trustee by the security afforded to it by the terms of this Agreement,
     the Trustee may require reasonable indemnity against such

                                       102

<PAGE>

     expense or liability as a condition to so proceeding. The reasonable
     expense of every such examination shall be paid by the Master Servicer, if
     an Event of Default shall have occurred and is continuing, and otherwise by
     the Certificateholder requesting the investigation;

               (vi) The Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     Affiliates, agents or attorneys provided that the Trustee shall remain
     liable for any acts of such Affiliates, agents or attorneys; and

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

          (b) It is intended that the Trust Fund formed hereunder shall
constitute, and that the affairs of the Trust Fund shall be conducted so as to
qualify the Trust Fund as three REMICs as defined in and in accordance with the
REMIC Provisions. In furtherance of such intention the Trustee shall:

          (i) to the extent that the affairs of the Trust are within its
     control, conduct such affairs of the Trust at all times that any
     Certificates are outstanding so as to maintain the status of the Trust as
     three REMICs under the REMIC Provisions and any other applicable federal,
     state and local laws;

          (ii) not knowingly or intentionally take any action or omit to take
     any action that would cause the termination of the REMIC status of REMIC I,
     REMIC II or REMIC III;

          (iii) pay the amount of any and all federal, state and local taxes,
     prohibited transaction taxes as defined in Section 860F of the Code, other
     than any amount due as a result of a transfer or attempted or purported
     transfer in violation of Section 5.02(f), imposed on REMIC I, REMIC II or
     REMIC III 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). The Trustee shall be
     entitled to reimbursement in accordance with Section 8.05; and

          (iv) Following the Closing Date, and except as otherwise provided in
     this Agreement, the Trustee shall not knowingly accept any contribution of
     assets to the Trust unless it shall have been provided with an Opinion of
     Counsel at the expense of the party delivering such assets acceptable to it
     to the effect that the inclusion of such assets in the Trust will not cause
     the Trust to fail to qualify as three REMICs at any time that any
     Certificates are outstanding or subject the Trust to any tax under the
     REMIC Provisions or other applicable provisions of federal, state and local
     law or ordinances.

          Section 8.03. TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.

                                       103

<PAGE>

          The recitals contained herein and in the Certificates (other than the
execution of the Certificates and relating to the acceptance and receipt of the
Mortgage Loans) shall be taken as the statements of the Company or the Master
Servicer, 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 (except that the
Certificates shall be duly and validly executed and authenticated by it as
Certificate Registrar) or of any Mortgage Loan or related document. Except as
otherwise provided herein, the Trustee shall not be accountable for the use or
application by the Company or the Master Servicer of any of the Certificates or
of the proceeds of such Certificates, or for the use or application of any funds
paid to the Company or the Master Servicer in respect of the Mortgage Loans or
deposited in or withdrawn from any of the Accounts by the Company or the Master
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 otherwise transact business with the
Company, Master Servicer with the same rights it would have if it were not
Trustee.

          Section 8.05. TRUSTEE'S FEES AND EXPENSES; INDEMNIFICATION.

          (a) The Trustee shall withdraw from the Distribution Account on each
Distribution Date (prior to the payments to Certificateholders pursuant to
Section 4.02 hereof) and pay to itself the Trustee Fee and , to the extent funds
therein are at anytime insufficient for such purpose, the Master Servicer shall
pay such fees. In addition, if for any Distribution Date the Trustee Fee is less
than $500, the Master Servicer shall pay to the Trustee an amount equal to the
excess of $500 over the Trustee Fee for such Distribution Date. The Master
Servicer shall pay the Trustee any additional amounts as separately agreed. When
the Trustee incurs expenses or renders services in connection with an Event of
Default described in Sections 7.01(iii) or 7.01(iv) such expenses (including the
fees and expenses of its counsel) and the compensation for such services are
intended to constitute expenses of administration under any bankruptcy law or
law relating to creditors' rights generally. In addition, the Master Servicer
covenants and agrees to indemnify the Trustee and its officers, directors,
employees and agents from, and hold it harmless against, any loss, liability or
expense (not including expenses, disbursements and advances incurred or made by
the Trustee, including the compensation and the expenses and disbursements of
its agents and counsel, in the ordinary course of the Trustee's performance in
accordance with the provisions of this Agreement) incurred by the Trustee
(including without limitation any loss, liability or expense relating to
environmental law) in connection with any claim or legal action or any pending
or threatened claim or legal action arising out of or in connection with the
acceptance or administration of its obligations and duties under this Agreement,
other than any loss, liability or expense (i) that constitutes a specific
liability of the Trustee pursuant to this Agreement or (ii) incurred by reason
of the Trustee's negligent action, negligent failure to act or willful
misconduct in the performance of duties or by reason of the Trustee's reckless
disregard of obligations and duties hereunder. Notwithstanding the foregoing,
except in the event that any such loss, liability or expense of the Trustee is
incurred by reason of the Master Servicer's willful misfeasance, bad faith or
gross negligence in the performance of duties or by reason of the Master
Servicer's reckless disregard of its obligations and duties

                                       104

hereunder, the Master Servicer shall be liable for any such loss, liability or
expense of the Trustee only upon and to the extent of the reimbursement to the
Master Servicer therefor pursuant to Section 3.07 hereof. This Section shall
survive termination of this Agreement or the resignation or removal of any
Trustee hereunder.

          Section 8.06. ELIGIBILITY REQUIREMENTS FOR TRUSTEE.

          The Trustee hereunder shall at all times be a corporation or a
national banking association having its principal office in a state and city
acceptable to the Company and organized and doing business under the laws of
such state or the United States of America, authorized under such laws to
exercise corporate trust powers, having a combined capital and surplus of at
least $50,000,000 and subject to supervision or examination by federal or state
authority. If such corporation or national banking 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 the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 8.07.

          Section 8.07. RESIGNATION AND REMOVAL OF THE TRUSTEE.

          (a) The Trustee may at any time resign and be discharged from the
trusts hereby created by giving written notice thereof to the Company. Upon
receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument, in duplicate, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee.

          (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 8.06 and shall fail to resign after
written request therefor by the Company, or if at any time the Trustee shall
become incapable of acting, or shall be adjudged bankrupt or insolvent, or a
receiver of the Trustee or of its property shall be appointed, or any public
officer shall take charge or control of the Trustee or of its property or
affairs for the purpose of rehabilitation, conservation or liquidation, then the
Company may remove the Trustee and appoint a successor trustee by written
instrument, in duplicate, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee. In addition, in the
event that the Company determines that the Trustee has failed (i) to distribute
or cause to be distributed to the Certificateholders any amount required to be
distributed hereunder, if such amount is held by the Trustee or its Paying Agent
(other than the Master Servicer or the Company) for distribution or (ii) to
otherwise observe or perform in any material respect any of its covenants,
agreements or obligations hereunder, and such failure shall continue unremedied
for a period of 5 days (in respect of clause (i) above) or 30 days (in respect
of clause (ii) above) after the date on which written notice of such failure,
requiring that the same be remedied, shall have been given to the Trustee by the

                                       105

<PAGE>

Company, then the Company may remove the Trustee and appoint a successor trustee
by written instrument delivered as provided in the preceding sentence. In
connection with the appointment of a successor trustee pursuant to the preceding
sentence, the Company shall, on or before the date on which any such appointment
becomes effective, obtain from each Rating Agency written confirmation that the
appointment of any such successor trustee will not result in the reduction of
the ratings on any class of the Certificates below the lesser of the then
current or original ratings on such Certificates.

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

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

          Section 8.08. SUCCESSOR TRUSTEE.

          (a) Any successor trustee appointed as provided in Section 8.07 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become fully vested with all
the rights, powers, duties and obligations of its predecessor hereunder, with
the like effect as if originally named as trustee herein. The predecessor
trustee shall deliver to the successor trustee all Mortgage Files and related
documents and statements held by it hereunder (other than any Mortgage Files at
the time held by a Custodian, which shall become the agent of any successor
trustee hereunder), and the Company, the Master 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.

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

          (c) Upon acceptance of appointment by a successor trustee as provided
in this Section, the Company shall mail notice of the succession of such trustee
hereunder to all Holders of Certificates at their addresses as shown in the
Certificate Register. If the Company 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 Company.

          Section 8.09. MERGER OR CONSOLIDATION OF TRUSTEE.

          Any corporation or national banking association into which the Trustee
may be merged or converted or with which it may be consolidated or any
corporation or national banking association resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation or national banking association succeeding to the business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation or national banking association shall be eligible under the
provisions of Section 8.06, without the execution or filing of any paper or any
further act on the part of any of the parties hereto, anything herein to the
contrary notwithstanding. The Trustee shall mail notice of any such merger or
consolidation to the Certificateholders at their address as shown in the
Certificate Register.

          Section 8.10. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.

          (a) Notwithstanding any other provisions hereof, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Fund or property securing the same may at the time be located, the
Master Servicer and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this Section
8.10, such powers, duties, obligations, rights and trusts as the Master Servicer
and the Trustee may consider necessary or desirable. All fees and expenses of
any co-trustee so appointed shall be paid by the Trustee out of its own funds.
If the Master Servicer shall not have joined in such appointment within 15 days
after the receipt by it of a request so to do, or in case an Event of Default
shall have occurred and be continuing, the Trustee alone shall have the power to
make such appointment. No co-trustee or separate trustee hereunder shall be
required to meet the terms of eligibility as a successor trustee under Section
8.06 hereunder and no notice to Holders of Certificates of the appointment of
co-trustee(s) or separate trustee(s) shall be required under Section 8.08
hereof.

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

          (c) Any notice, request or other writing given to the Trustee shall be
deemed to have been given to each of the then separate trustees and co-trustees,
as effectively as if given to each of them. Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article VIII. Each separate trustee and co-trustee, upon its acceptance
of

                                       107

<PAGE>

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.

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

          Section 8.11. APPOINTMENT OF CUSTODIANS.

          The Trustee may, with the consent of the Master Servicer and the
Company, appoint one or more Custodians who are not Affiliates of the Company,
the Master Servicer or any Seller to hold all or a portion of the Mortgage Files
as agent for the Trustee, by entering into a Custodial Agreement. Subject to
Article VIII, the Trustee agrees to comply with the terms of each Custodial
Agreement and to enforce the terms and provisions thereof against the Custodian
for the benefit of the Certificateholders. Each Custodian shall be a depository
institution subject to supervision by federal or state authority, shall have a
combined capital and surplus of at least $15,000,000 and shall be qualified to
do business in the jurisdiction in which it holds any Mortgage File. Each
Custodial Agreement may be amended only as provided in Section 11.01. The
Trustee shall notify the Certificateholders of the appointment of any Custodian
pursuant to this Section 8.11.

          Section 8.12. APPOINTMENT OF OFFICE OR AGENCY.

          The Trustee will maintain an office or agency in the City of New York
where Certificates may be surrendered for registration of transfer or exchange.
The Trustee initially designates its offices located at 14 Wall Street, 8th
Floor, New York, New York 10005 for the purpose of keeping the Certificate
Register. The Trustee will maintain an office at the address stated in Section
11.05(c) hereof where notices and demands to or upon the Trustee in respect of
this Agreement may be served.

                                   ARTICLE IX

                                   TERMINATION

          Section 9.01. TERMINATION UPON PURCHASE BY THE MASTER SERVICER OR THE
                        COMPANY OR LIQUIDATION OF ALL MORTGAGE LOANS.

          (a) Subject to Sections 9.02 and 9.03 hereof, the respective
obligations and responsibilities of the Company, the Master Servicer and the
Trustee created hereby in respect of the Certificates (other than the obligation
of the Trustee to make certain payments after the Final Distribution Date to
Certificateholders and the obligation of the Company to send certain notices as
hereinafter set forth) shall terminate upon the last action required to be taken
by the Trustee on the Final Distribution Date pursuant to this Article IX
following the earlier of:

               (i) the Distribution Date on which the aggregate Certificate
     Principal Balance of the Certificates has been reduced to zero;

               (ii) the later of the final payment or other liquidation of the
     last Mortgage Loan remaining in the Trust Fund or the disposition of all
     REO Property, or

               (iii) the optional purchase by the Master Servicer of all
     Mortgage Loans and all property acquired in respect of any Mortgage Loan
     remaining in the Trust Fund as described below; PROVIDED, HOWEVER, that in
     no event shall the trust created hereby continue beyond the earlier of (A)
     the expiration of 21 years from the death of the last survivor of the
     descendants of Joseph P. Kennedy, the late ambassador of the United States
     to the Court of St. James, living on the date hereof and (B) the Latest
     Possible Maturity Date; and provided further that the purchase price set
     forth below shall be increased as is necessary, as determined by the Master
     Servicer, to avoid disqualification of any of REMIC I, REMIC II or REMIC
     III as a REMIC; PROVIDED, FURTHER, that, if the amount due under any
     Regular Certificate shall not have been reduced to zero prior to the Latest
     Possible Maturity Date, the Holders of the Class R Certificates shall be
     required to terminate this Agreement in the same manner as provided for the
     Master Servicer in the succeeding sentence.

          The Master Servicer (the party exercising such right, the
"Terminator"), may, at its option, terminate this Agreement by purchasing all of
the assets of the Trust Fund (including any REO Property) pursuant to clause
(iii) above on any Distribution Date when the Pool Principal Balance is less
than ten percent of the sum of the Pool Principal Balance of the Initial
Mortgage Loans as of the Cut-off Date and the Original Pre-Funded Amount (the
"Optional Termination Date") at a price equal to the greater of (A) the
aggregate Purchase Price of all the Mortgage Loans included in REMIC I, plus the
appraised value of each REO Property, if any, included in REMIC I, such
appraisal to be conducted by an appraiser mutually agreed upon by the Terminator
and the Trustee in their reasonable discretion and (B) the aggregate fair market
value of all of the assets of REMIC I (as determined by the Terminator and the
Trustee, as of the close of business on the third Business Day next preceding
the date upon which notice of any such termination is furnished to
Certificateholders pursuant to 9.01(b), plus accrued and unpaid interest thereon
at the weighted

                                       109

<PAGE>

average of the Mortgage Rates through the end of the Due Period preceding the
Final Distribution Date, together with any amounts due to the Master Servicer
for unpaid Servicing Fees and any unreimbursed advances (the "Termination
Price"). By acceptance of the Class R Certificates, the Holder of each Class of
Class R Certificates agrees, in connection with any termination hereunder, to
assign and transfer any amounts in excess of par, and to the extent received in
respect of such termination, to pay any such amounts to the Holders of the Class
CE Certificates.

          (b) The Master Servicer shall give the Trustee not less than 60 days'
prior notice of the Distribution Date on which the Master Servicer anticipates
that the final distribution will be made to Certificateholders (whether as a
result of the exercise by the Master Servicer of its right to purchase the
assets of the Trust Fund or otherwise). Notice of any termination, specifying
the anticipated Final Distribution Date (which shall be a date that would
otherwise be a Distribution Date) upon which the Certificateholders may
surrender their Certificates to the Trustee (if so required by the terms hereof)
for payment of the final distribution and cancellation, shall be given promptly
by the Trustee by letter to the 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 specifying:

               (i) the anticipated Final Distribution Date upon which final
payment of the Certificates is anticipated to be made upon presentation and
surrender of Certificates at the office or agency of the Trustee therein
designated,

               (ii) the amount of any such final payment, if known, and

               (iii) that the Record Date otherwise applicable to such
Distribution Date is not applicable, and that payment will be made only upon
presentation and surrender of the Certificates at the office or agency of the
Trustee therein specified.

     In the event such notice is given by the Terminator, the Terminator shall
deposit in the Distribution Account before the Final Distribution Date in
immediately available funds the Termination Price.

          (c) Upon presentation and surrender of the Certificates by the
Certificateholders, the Trustee shall distribute to the Certificateholders the
amount otherwise distributable on such Distribution Date, or (ii) if the
Terminator elected to so repurchase, the Trustee shall distribute to the
Certificateholders the Termination Price in the order and priority set forth in
Section 4.02 hereof.

          (d) In the event that any Certificateholders shall not surrender their
Certificates for final payment and cancellation on or before the Final
Distribution Date (if so required by the terms hereof), the Trustee shall on
such date cause all funds in the Distribution Account not distributed in final
distribution to Certificateholders to be withdrawn therefrom and credited to the
remaining Certificateholders by depositing such funds in a separate escrow
account for the benefit of such Certificateholders, and the Master Servicer (if
it exercised its right to purchase the assets of the Trust Fund), or the Trustee
(in any other case) shall give a second written notice to the remaining
Certificateholders to surrender their Certificates for cancellation and receive
the final distribution

                                       110

<PAGE>

with respect thereto. If within six months after the second notice any
Certificate shall not have been surrendered for cancellation, the Trustee shall
take appropriate steps as directed by the Master Servicer to contact the
remaining Certificateholders concerning surrender of their Certificates. The
costs and expenses of maintaining the escrow account and of contacting
Certificateholders shall be paid out of the assets which remain in the escrow
account. If within nine months after the second notice any Certificates shall
not have been surrendered for cancellation, the Trustee shall pay to the Master
Servicer all amounts distributable to the holders thereof and the Master
Servicer shall thereafter hold such amounts until distributed to such holders.
No interest shall accrue or be payable to any Certificateholder on any amount
held in the escrow account or by the Master Servicer as a result of such
Certificateholder's failure to surrender its Certificate(s) for final payment
thereof in accordance with this Section 9.01 and the Certificateholders shall
look only to the Master Servicer for such payment.

          Section 9.02. TERMINATION OF REMIC II AND REMIC III.

          REMIC II and REMIC III shall be terminated on the earlier of the Final
Distribution Date and the date on which each is deemed to receive the last
deemed distributions on the Uncertificated REMIC I Regular Interests and
Uncertificated REMIC II Regular Interests, respectively, and the date on which
the last distribution on the Regular Certificates and Class R-III Certificates
is made.

          Section 9.03. ADDITIONAL TERMINATION REQUIREMENTS.

          (a) REMIC I, REMIC II or REMIC III, as the case may be, shall be
terminated in accordance with the following additional requirements, unless
(subject to Section 10.01(f)) the Trustee and the Master Servicer have received
an Opinion of Counsel (which Opinion of Counsel shall not be an expense of the
Trustee) to the effect that the failure of REMIC I, REMIC II or REMIC III, as
the case may be, to comply with the requirements of this Section 9.03 will not
(i) result in the imposition on the Trust Fund of taxes on "prohibited
transactions," as described in Section 860F of the Code, or (ii) cause either
REMIC I, REMIC II or REMIC III to fail to qualify as a REMIC at any time that
any Certificate is outstanding:

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

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

                                       111

<PAGE>

               (iii) If the Master Servicer or the Class C or Class R
     Certificateholders is exercising its right to purchase the assets of the
     Trust Fund, the Master Servicer, Class C or Class R Certificateholders
     shall, during the 90-day liquidation period and at or prior to the Final
     Distribution Date, purchase all of the assets of the Trust Fund for cash;
     PROVIDED, HOWEVER, that in the event that a calendar quarter ends after the
     commencement of the 90-day liquidation period but prior to the Final
     Distribution Date, neither the Master Servicer nor the Class C or Class R
     Certificateholders shall purchase any of the assets of the Trust Fund prior
     to the close of that calendar quarter.

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

                                REMIC PROVISIONS

          Section 10.01. REMIC ADMINISTRATION.

          (a) The REMIC Administrator shall make elections to treat each of
REMIC I, REMIC II and REMIC III as a REMIC under the Code and, if necessary,
under applicable state law. Each such election will be made on Form 1066 or
other appropriate federal tax or information return (including Form 8811) or any
appropriate state return for the taxable year ending on the last day of the
calendar year in which the Certificates are issued. For purposes of the REMIC I
election in respect of the Trust Fund, the Uncertificated REMIC I Regular
Interests shall be designated as the "regular interests" and the Class R-I
Certificates shall be designated as the sole class of "residual interest" in
REMIC I. For purposes of the REMIC II election in respect of the Trust Fund and
the Uncertificated REMIC II Regular Interests shall be designated as the
"regular interests" and the Class R-II Certificates shall be designated as the
sole class of "residual interest" in REMIC II. For purposes of the REMIC III
election in respect of the Trust Fund, the Regular Certificates shall be
designated as the "regular interests" and the Class R-III Certificates shall be
designated as the sole class of "residual interests" in REMIC III. The REMIC
Administrator and the Trustee shall not permit the creation of any "interests"
(within the meaning of Section 860G of the Code) in REMIC I, REMIC II or REMIC
III other than the Uncertificated REMIC I Regular Interests and the Class R-I
Certificates, the Uncertificated REMIC II Regular Interests and the Class R-II
Certificates and the Regular Certificates and the Class R-III Certificates,
respectively.

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

          (c) The REMIC Administrator shall hold a Class R-I Certificate, a
Class R-II Certificate and a Class R-III Certificate representing a 0.01%
Percentage Interest of the Class R-I Certificates, a 0.01% Percentage Interest
of the Class R-II Certificates and a 0.01% Percentage Interest of the Class
R-III Certificates respectively, and shall be designated as "the tax matters
person" with respect to REMIC I, REMIC II and REMIC III in the manner provided
under Treasury regulations section 1.860F-4(d) and temporary Treasury
regulations section 301.6231(a)(7)-1. The REMIC Administrator, as tax matters
person, shall (i) act on behalf of REMIC I, REMIC II and REMIC III in relation
to any tax matter or controversy involving the Trust Fund and (ii) represent the
Trust Fund in any administrative or judicial proceeding relating to an
examination or audit by any governmental taxing authority with respect thereto.
The legal expenses, including without limitation attorneys' or accountants'
fees, and costs of any such proceeding and any liability resulting therefrom
shall be expenses of the Trust Fund and the REMIC Administrator shall be
entitled to reimbursement therefor out of amounts attributable to the Mortgage
Loans on deposit in the Certificate Account as provided by Section 3.07 unless
such legal expenses and costs are incurred by reason of the REMIC
Administrator's willful misfeasance, bad faith or gross negligence. If the REMIC
Administrator is no longer the Master Servicer hereunder, at its option the
REMIC Administrator may continue its duties as REMIC Administrator and shall be
paid reasonable

                                       113

compensation not to exceed $3,000 per year by any successor Master Servicer
hereunder for so acting as the REMIC Administrator.

          (d) The REMIC Administrator shall prepare or cause to be prepared all
of the Tax Returns that it determines are required with respect to any of REMIC
I, REMIC II or REMIC III created hereunder and deliver such Tax Returns in a
timely manner to the Trustee and the Trustee shall sign and file such Tax
Returns in a timely manner. The expenses of preparing such returns shall be
borne by the REMIC Administrator without any right of reimbursement therefor.
The REMIC Administrator agrees to indemnify and hold harmless the Trustee with
respect to any tax or liability arising from the Trustee's signing of Tax
Returns that contain errors or omissions. The Trustee and Master Servicer shall
promptly provide the REMIC Administrator with such information, within their
respective control, as the REMIC Administrator may from time to time request for
the purpose of enabling the REMIC Administrator to prepare Tax Returns.

          (e) The REMIC Administrator shall provide (i) to any Transferor of a
Class R Certificate such information as is necessary for the application of any
tax relating to the transfer of a Class R Certificate to any Person who is not a
Permitted Transferee, (ii) to the Trustee and the Trustee shall forward to the
Certificateholders such information or reports as are required by the Code or
the REMIC Provisions including reports relating to interest, original issue

(iii) to the Internal Revenue Service the name, title, address and telephone
number of the person who will serve as the representative of each of REMIC I,
REMIC II and REMIC III.

          (f) The Master Servicer and the REMIC Administrator shall take such
actions and shall cause each of REMIC I, REMIC II and REMIC III created
hereunder to take such actions as are reasonably within the Master Servicer's or
the REMIC Administrator's control and the scope of its duties more specifically
set forth herein as shall be necessary or desirable to maintain the status
thereof as REMICs under the REMIC Provisions (and the Trustee shall assist the
Master Servicer and the REMIC Administrator, to the extent reasonably requested
by the Master Servicer and the REMIC Administrator to do so). The Master
Servicer and the REMIC Administrator shall not knowingly or intentionally take
any action, cause each of REMIC I, REMIC II or REMIC III to take any action or
fail to take (or fail to cause to be taken) any action reasonably within their
respective control, that, under the REMIC Provisions, if taken or not taken, as
the case may be, could (i) endanger the status of any of REMIC I , REMIC II or
REMIC III as a REMIC or (ii) result in the imposition of a tax upon each of
REMIC I, REMIC II or REMIC III (including but not limited to the tax on
prohibited transactions as defined in Section 860F(a)(2) of the Code and the tax
on contributions to a REMIC set forth in Section 860G(d) of the Code) (either
such event, in the absence of an Opinion of Counsel or the indemnification
referred to in this sentence, an "Adverse REMIC Event") unless the Master
Servicer or the REMIC Administrator, as applicable, has received an Opinion of
Counsel (at the expense of the party seeking to take such action or, if such
party fails to pay such expense, and the Master Servicer or the REMIC
Administrator, as applicable, determines that taking such action is in the best
interest of the Trust Fund and the Certificateholders, at the expense of the
Trust Fund, but in no event at the expense of the Master Servicer, the REMIC
Administrator or the Trustee) to the effect that the contemplated action will
not, with respect to each of REMIC I, REMIC II or REMIC III created hereunder,
endanger such status or, unless the Master

                                       114

<PAGE>

Servicer, the REMIC Administrator or both, as applicable, determine in its or
their sole discretion to indemnify the Trust Fund against the imposition of such
a tax, result in the imposition of such a tax. Wherever in this Agreement a
contemplated action may not be taken because the timing of such action might
result in the imposition of a tax on the Trust Fund, or may only be taken
pursuant to an Opinion of Counsel that such action would not impose a tax on the
Trust Fund, such action may nonetheless be taken provided that the indemnity
given in the preceding sentence with respect to any taxes that might be imposed
on the Trust Fund has been given and that all other preconditions to the taking
of such action have been satisfied. The Trustee shall not take or fail to take
any action (whether or not authorized hereunder) as to which the Master Servicer
or the REMIC Administrator, as applicable, has advised it in writing that it has
received an Opinion of Counsel to the effect that an Adverse REMIC Event could
occur with respect to such action. In addition, prior to taking any action with
respect to REMIC I, REMIC II or REMIC III or their assets, or causing REMIC I,
REMIC II or REMIC III to take any action, which is not expressly permitted under
the terms of this Agreement, the Trustee will consult with the Master Servicer
or the REMIC Administrator, as applicable, or its designee, in writing, with
respect to whether such action could cause an Adverse REMIC Event to occur with
respect to REMIC I, REMIC II or REMIC III, and the Trustee shall not take any
such action or cause REMIC I, REMIC II or REMIC III to take any such action as
to which the Master Servicer or the REMIC Administrator, as applicable, has
advised it in writing that an Adverse REMIC Event could occur. The Master
Servicer or the REMIC Administrator, as applicable, may consult with counsel to
make such written advice, and the cost of same shall be borne by the party
seeking to take the action not expressly permitted by this Agreement, but in no
event at the expense of the Master Servicer or the REMIC Administrator. At all
times as may be required by the Code, the Master Servicer will to the extent
within its control and the scope of its duties more specifically set forth
herein, maintain substantially all of the assets of REMIC I, REMIC II or REMIC
III as "qualified mortgages" as defined in Section 860G(a)(3) of the Code and
"permitted investments" as defined in Section 860G(a)(5) of the Code.

          (g) In the event that any tax is imposed on "prohibited transactions"
of REMIC I, REMIC II or REMIC III created hereunder as defined in Section
860F(a)(2) of the Code, on "net income from foreclosure property" of REMIC I,
REMIC II or REMIC III as defined in Section 860G(c) of the Code, on any
contributions to REMIC I, REMIC II or REMIC III after the Startup Day therefor
pursuant to Section 860G(d) of the Code, or any other tax is imposed by the Code
or any applicable provisions of state or local tax laws, such tax shall be
charged (i) to the Master Servicer, if such tax arises out of or results from a
breach by the Master Servicer of any of its obligations under this Agreement or
the Master Servicer has in its sole discretion determined to indemnify the Trust
Fund against such tax, (ii) to the Trustee, if such tax arises out of or results
from a breach by the Trustee of any of its obligations under Article VIII or
this Article X, or (iii) otherwise against amounts on deposit in the Certificate
Account as provided by Section 3.07.

          (h) The Trustee and the Master Servicer shall, for federal income tax
purposes, maintain books and records with respect to REMIC I, REMIC II and REMIC
III on a calendar year and on an accrual basis or as otherwise may be required
by the REMIC Provisions.

          (i) Following the Startup Day, neither the Master Servicer nor the
Trustee shall accept any contributions of assets to REMIC I, REMIC II or REMIC
III unless (subject to 10.01(f))

                                       115

<PAGE>

the Master Servicer and the Trustee shall have received an Opinion of Counsel
(at the expense of the party seeking to make such contribution) to the effect
that the inclusion of such assets in REMIC I, REMIC II or REMIC III will not
cause REMIC I, REMIC II or REMIC III to fail to qualify as REMICs at any time
that any Certificates are outstanding or subject REMIC I, REMIC II or REMIC III
to any tax under the REMIC Provisions or other applicable provisions of federal,
state and local law or ordinances.

          (j) Neither the Master Servicer nor the Trustee shall (subject to
Section 10.01(f)) enter into any arrangement by which REMIC I, REMIC II or REMIC
III will receive a fee or other compensation for services nor permit either such
REMIC 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.

          (k) Solely for the purposes of Section 1.860G-1(a)(4)(iii) of the
Treasury Regulations, the "latest possible maturity date" by which the
Certificate Principal Balance of each Class of Certificates or each Component
representing a regular interest in REMIC III, the Uncertificated Principal
Balance of each Uncertificated REMIC I Regular Interest and the Uncertificated
Principal Balance of each Uncertificated REMIC II Regular Interest would be
reduced to zero is May 15, 2030, which is the Distribution Date immediately
following the maturity date for the Mortgage Loan with the latest scheduled
maturity date.

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

          (m) Neither the Trustee nor the Master Servicer shall sell, dispose of
or substitute for any of the Mortgage Loans (except in connection with (i) the
default, imminent default or foreclosure of a Mortgage Loan, including but not
limited to, the acquisition or sale of a Mortgaged Property acquired by deed in
lieu of foreclosure, (ii) the bankruptcy of Trust Fund, (iii) the termination of
REMIC I, REMIC II or REMIC III pursuant to Article IX of this Agreement or (iv)
a purchase of Mortgage Loans pursuant to Article II or III of this Agreement)
nor acquire any assets for REMIC I, REMIC II or REMIC III, nor sell or dispose
of any investments in the Certificate Account or the Certificate Account for
gain nor accept any contributions to REMIC I, REMIC II or REMIC III after the
Closing Date unless it has received an Opinion of Counsel that such sale,
disposition, substitution or acquisition will not (a) affect adversely the
status of REMIC I, REMIC II or REMIC III as a REMIC or (b) unless the Master
Servicer has determined in its sole discretion to indemnify the Trust Fund
against such tax, cause REMIC I, REMIC II or REMIC III to be subject to a tax on
"prohibited transactions" or "contributions" pursuant to the REMIC Provisions.

          Section 10.02. MASTER SERVICER, REMIC ADMINISTRATOR AND TRUSTEE
                         INDEMNIFICATION.

          (a) The Trustee agrees to indemnify the Trust Fund, the Company, the
REMIC Administrator and the Master Servicer for any taxes and costs including,
without limitation, any reasonable attorneys fees imposed on or incurred by the
Trust Fund, the Company or the Master

Servicer, as a result of a breach of the Trustee's covenants set forth in
Article VIII or this Article X. In the event that WMC Mortgage Corp. is no
longer the Master Servicer, the Trustee shall indemnify WMC Mortgage Corp. for
any taxes and costs including, without limitation, any reasonable attorneys fees
imposed on or incurred by WMC Mortgage Corp. as a result of a breach of the
Trustee's covenants set forth in Article VIII or this Article X.

          (b) The REMIC Administrator agrees to indemnify the Trust Fund, the
Company, the Master Servicer and the Trustee for any taxes and costs (including,
without limitation, any reasonable attorneys' fees) imposed on or incurred by
the Trust Fund, the Company, the Master Servicer or the Trustee, as a result of
a breach of the REMIC Administrator's covenants set forth in this Article X with
respect to compliance with the REMIC Provisions, including without limitation,
any penalties arising from the Trustee's execution of Tax Returns prepared by
the REMIC Administrator that contain errors or omissions; provided, however,
that such liability will not be imposed to the extent such breach is a result of
an error or omission in information provided to the REMIC Administrator by the
Master Servicer in which case Section 10.02(c) will apply.

          (c) The Master Servicer agrees to indemnify the Trust Fund, the
Company, the REMIC Administrator and the Trustee for any taxes and costs
(including, without limitation, any reasonable attorneys' fees) imposed on or
incurred by the Trust Fund, the Company or the Trustee, as a result of a breach
of the Master Servicer's covenants set forth in this Article X or in Article III
with respect to compliance with the REMIC Provisions, including without
limitation, any penalties arising from the Trustee's execution of Tax Returns
prepared by the Master Servicer that contain errors or omissions.

          Section 11.01. AMENDMENT.

          (a) This Agreement may be amended from time to time by the Company,
the Master Servicer and the Trustee, without the consent of any of the
Certificateholders:

            (i) to cure any ambiguity,

            (ii) to correct or supplement any provisions herein, which may be
     inconsistent with any other provisions herein or to correct any error,

            (iii) to modify, eliminate or add to any of its provisions to such
     extent as shall be necessary or desirable to maintain the qualification of
     REMIC I, REMIC II or REMIC III as a REMIC at all times that any Certificate
     is outstanding or to avoid or minimize the risk of the imposition of any
     tax on the Trust Fund pursuant to the Code that would be a claim against
     the Trust Fund, provided that the Trustee has received an Opinion of
     Counsel to the effect that (A) such action is necessary or desirable to
     maintain such qualification or to avoid or minimize the risk of the
     imposition of any such tax and (B) such action will not adversely affect in
     any material respect the interests of any Certificateholder,

            (iv) to change the timing and/or nature of deposits into the
     Certificate Account or the Distribution Account or to change the name in
     which the Distribution Account is maintained, provided that (A) the
     Determination Date shall in no event be later than the related Distribution
     Date, (B) such change shall not, as evidenced by an Opinion of Counsel,
     adversely affect in any material respect the interests of any
     Certificateholder and (C) such change shall not result in a reduction of
     the rating assigned to any Class of Certificates below the lower of the
     then-current rating or the rating assigned to such Certificates as of the
     Closing Date, as evidenced by a letter from each Rating Agency to such
     effect,

            (v) to modify, eliminate or add to the provisions of Section 5.02(f)
     or any other provision hereof restricting transfer of the Class R-I, Class
     R-II and Class III Certificates by virtue of their being the "residual
     interests" in REMIC I, REMIC II and REMIC III, respectively; provided that
     (A) such change shall not result in reduction of the rating assigned to any
     such Class of Certificates below the lower of the then-current rating or
     the rating assigned to such Certificates as of the Closing Date, as
     evidenced by a letter from each Rating Agency to such effect, and (B) such
     change shall not (subject to Section 10.01(f)), as evidenced by an Opinion
     of Counsel (at the expense of the party seeking so to modify, eliminate or
     add such provisions), cause REMIC I, REMIC II or REMIC III or any of the
     Certificateholders (other than the transferor) to be subject to a federal
     tax caused by a transfer to a Person that is not a Permitted Transferee, or

                                       118

<PAGE>

            (vi) to make any other provisions with respect to matters or
     questions arising under this Agreement which shall not be materially
     inconsistent with the provisions of this Agreement, provided that such
     action shall not, as evidenced by an Opinion of Counsel, adversely affect
     in any material respect the interests of any Certificateholder and is
     authorized or permitted under the terms of this Agreement.

          (b) This Agreement may also be amended from time to time by the
Company, the Master Servicer and the Trustee with the consent of the Holders of
Certificates evidencing in the aggregate not less than 66% of the Percentage
Interests 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 of such Class; PROVIDED, HOWEVER, that no such amendment
shall:

                    (i) reduce in any manner the amount of, or delay the timing
     of, payments which are required to be distributed on any Certificate
     without the consent of the Holder of such Certificate, or

                    (ii) adversely affect in any material respect the interest
     of the Holders of Certificates of any Class in a manner other than as
     described in clause (i) hereof without the consent of Holders of
     Certificates of such Class evidencing, as to such Class, Percentage
     Interests aggregating not less than 66%, or

                    (iii) reduce the aforesaid percentage of Certificates of any
     Class the Holders of which are required to consent to any such amendment,
     in any such case without the consent of the Holders of all Certificates of
     such Class then outstanding.

          (c) 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 (subject to Section 10.01(f) and at
the expense of the party seeking such amendment) to the effect that such
amendment or the exercise of any power granted to the Master Servicer, the
Company or the Trustee in accordance with such amendment will not result in the
imposition of a federal tax on the Trust Fund or cause any of REMIC I, REMIC II
or REMIC III to fail to qualify as a REMIC at any time that any Certificate is
outstanding. The Trustee may but shall not be obligated to enter into any
amendment pursuant to this Section that affects its rights, duties and
immunities under this Agreement or otherwise; provided however, such consent
shall not be unreasonably withheld.

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

          (e) The Company shall have the option, in its sole discretion, to
obtain and deliver to the Trustee any corporate guaranty, payment obligation,
irrevocable letter of credit, surety bond, insurance policy or similar
instrument or a reserve fund, or any combination of the foregoing, for the
purpose of protecting the Holders of the Class R Certificates against any or all
Realized Losses or other shortfalls. Any such instrument or fund shall be held
by the Trustee for the benefit of the Class R Certificateholders, but shall not
be and shall not be deemed to be under any circumstances included in the Trust
Fund. To the extent that any such instrument or fund constitutes a reserve fund
for federal income tax purposes, (i) any reserve fund so established shall be an
outside reserve fund and not an asset of the Trust Fund, (ii) any such reserve
fund shall be owned by the Company, and (iii) amounts transferred by the Trust
Fund to any such reserve fund shall be treated as amounts distributed by the
Trust Fund to the Company or any successor, all within the meaning of Treasury
regulations Section 1.860G-2(h) in effect as of the Cut-off Date. In connection
with the provision of any such instrument or fund, this Agreement and any
provision hereof may be modified, added to, deleted or otherwise amended in any
manner that is related or incidental to such instrument or fund or the
establishment or administration thereof, such amendment to be made by written
instrument executed or consented to by the Company and such related insurer but
without the consent of any Certificateholder and without the consent of the
Master Servicer or the Trustee being required unless any such amendment would
impose any additional obligation on, or otherwise adversely affect the interests
of the Certificateholders, the Master Servicer or the Trustee, as applicable;
provided that the Company obtains (subject to Section 10.01(f)) an Opinion of
Counsel (which need not be an opinion of Independent counsel) to the effect that
any such amendment will not cause (a) any federal tax to be imposed on the Trust
Fund, including without limitation, any federal tax imposed on "prohibited
transactions" under Section 860F(a)(1) of the Code or on "contributions after
the startup date" under Section 860G(d)(1) of the Code and (b) any of REMIC I,
REMIC II or REMIC III to fail to qualify as a REMIC at any time that any
Certificate is outstanding.

          Section 11.02. RECORDATION OF AGREEMENT; COUNTERPARTS.

          (a) To the extent permitted by applicable law, 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 Master Servicer and at its expense on direction by the Trustee
(pursuant to the request of Holders of Certificates entitled to at least 25% of
the Voting Rights), but only upon direction accompanied by an Opinion of Counsel
to the effect that such recordation materially and beneficially affects the
interests of the Certificateholders.

          (b) 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 11.03. LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.

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

          (b) No Certificateholder shall have any right to vote (except as
expressly 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 person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

          (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee a written notice of default
and of the continuance thereof, as hereinbefore provided, and unless also the
Holders of Certificates of any Class evidencing in the aggregate not less than
25% of the related Percentage Interests of such Class, shall have made written
request upon the Trustee to institute such action, suit or proceeding in its own
name as Trustee hereunder and shall have offered to the Trustee such reasonable
indemnity as it may require against the costs, expenses and liabilities to be
incurred therein or thereby shall have given its written consent, 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 of any Class shall have any right in any
manner whatever by virtue of any provision of this Agreement to affect, disturb
or prejudice the rights of the Holders of any other of such Certificates of such

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
Certificateholders of such Class or all Classes, as the case may be. For the
protection and enforcement of the provisions of this Section 11.03, each and
every Certificateholder and the Trustee shall be entitled to such relief as can
be given either at law or in equity.

          Section 11.04. GOVERNING LAW.

in accordance with the laws of the State of New York, without regard to any
applicable conflicts of law provisions, the obligations, rights and remedies of
the parties hereunder shall be determined in accordance with such laws.

"Resecuritized Certificates"), the Company may deposit such Resecuritized
Certificates into a new REMIC, grantor trust, FASIT or custodial arrangement (a
"Restructuring Vehicle") to be held by the Trustee pursuant to a Supplemental
Article. The instrument adopting such Supplemental Article shall be executed by
the Company, the Master Servicer and the Trustee; provided, that neither the
Master Servicer nor the Trustee shall withhold their consent thereto if their
respective interests would not be materially adversely affected thereby. To the
extent that the terms of the Supplemental Article do not in any way affect any
provisions of this Agreement as to any of the Certificates initially issued
hereunder, the adoption of the Supplemental Article shall not constitute an
"amendment" of this Agreement.

          Each Supplemental Article shall set forth all necessary provisions
relating to the holding of the Resecuritized Certificates by the Trustee, the
establishment of the Restructuring Vehicle, the issuing of various classes of
new certificates by the Restructuring Vehicle and the distributions to be made
thereon, and any other provisions necessary to the purposes thereof. In
connection with each Supplemental Article, the Company shall deliver to the
Trustee an Opinion of Counsel to the effect that (i) the Restructuring Vehicle
will qualify as a REMIC, grantor trust, FASIT or other entity not subject to
taxation for federal income tax purposes and (ii) the adoption of the
Supplemental Article will not endanger the status of REMIC I, REMIC II or REMIC
III as a REMIC or (subject to Section 10.01(f)) result in the imposition of a
tax upon the Trust Fund (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the

tax on contributions to a REMIC as set forth in Section 860G(d) of the Code). In
addition, the Company must receive confirmation from the Rating Agencies that
such Supplemental Article will not cause a downgrade in the then current-rating
on any Class of Certificates.

          Section 11.09. THIRD PARTY BENEFICIARIES.

          This Agreement will inure to the benefit of and be binding upon the
parties hereto, the Certificateholders and their respective successors and
permitted assigns. Except as otherwise provided in this Agreement, no other
Person will have any right or obligation hereunder. The Trustee shall have the
right to exercise all rights of the Trust Fund under this Agreement.

Initial Certificate Principal Balance of all Class A Certificates, both as

set forth hereafter. To the extent not defined herein, the capitalized terms
used herein have the meanings assigned in the Agreement. This Certificate is
issued under and is subject to the terms, provisions and conditions of the
Agreement, to which Agreement the Holder of this Certificate by virtue of the
acceptance hereof assents and by which such Holder is bound.

          Pursuant to the terms of the Agreement, a distribution will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last day (or if such last day is not
a Business Day, the Business Day immediately preceding such last day) of the
month immediately preceding the month of such distribution (the "Record Date"),
in an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount of required to be distributed to Holders of Class A
Certificates on such Distribution Date.

          Distributions on this Certificate will be made either by the Master
Servicer acting on behalf of the Trustee or by a Paying Agent appointed by the
Trustee in immediately available funds (by wire transfer or otherwise) for the
account of the Person entitled thereto if such Person shall have so notified the
Master Servicer or such Paying Agent, or by check mailed to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register.

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

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

          The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement.

          As provided in the Agreement, withdrawals from the Certificate Account
created for the benefit of Certificateholders may be made by the Master Servicer
from time to time for purposes

                                      A-1-2

<PAGE>

other than distributions to Certificateholders, such purposes including without
limitation reimbursement to the Company and the Master Servicer of certain
expenses incurred by either of them.

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

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

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

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

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

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

          The obligations created by the Agreement in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to Certificateholders of all amounts held by

                                      A-1-3

or on behalf of the Trustee and required to be paid to them pursuant to the
Agreement following the earlier of (i) the Distribution Date on which the
Aggregate Certificate Principal Balance has been reduced to zero, (ii) the
maturity or other liquidation of the last Mortgage Loan subject thereto or the
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and (iii) the purchase by the party designated
in the Agreement at a price determined as provided in the Agreement from REMIC I
of all the Mortgage Loans and all property acquired in respect of such Mortgage
Loans. The Agreement permits, but does not require, the party designated in the
Agreement to purchase from REMIC I all the Mortgage Loans and all property
acquired in respect of any Mortgage Loan at a price determined as provided in
the Agreement. The exercise of such right will effect early retirement of the
Certificates; however, such right to purchase may only be exercised on any
Distribution Date when the Pool Principal Balance is less than 10% of the sum of
the Pool Principal Balance as of the Initial Cut-off Date and the Original
Pre-Funded Amount.

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

          Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

Initial Certificate Principal Balance of all Class [M-1][M-2][B] Certificates,
both as specified above) in certain distributions with respect to the Trust Fund
consisting primarily of an interest in a pool of closed end, adjustable rate and
fixed rate, one- to four-family, first lien, sub-prime mortgage loans (the
"Mortgage Loans") sold to the Trust Fund by WMC Secured Assets Corp.
(hereinafter called the "Company", which term includes any successor

                                      A-2-2

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

          Pursuant to the terms of the Agreement, a distribution will be made on
the 15th day of each month or, if such 15th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last day (or if such last day is not
a Business Day, the Business Day immediately preceding such last day) of the
month immediately preceding the month of such distribution (the "Record Date"),
in an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount of required to be distributed to Holders of Class
[M-1][M-2][B] Certificates on such Distribution Date.

          Distributions on this Certificate will be made either by the Master
Servicer acting on behalf of the Trustee or by a Paying Agent appointed by the
Trustee in immediately available funds (by wire transfer or otherwise) for the
account of the Person entitled thereto if such Person shall have so notified the
Master Servicer or such Paying Agent, or by check mailed to the address of the
Person entitled thereto, as such name and address shall appear on the
Certificate Register.

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

          Transfers of this Certificate to a Plan, to a trustee or other person
acting on behalf of any Plan, or to any other person using the assets of any
Plan in the form of Definitive Certificates, will not be registered by the
Trustee unless the transferee provides the Company, the Trustee and the Master
Servicer with an opinion of counsel satisfactory to the Company, the Trustee and
the Master Servicer, which opinion will not be at the expense of the Company,
the Trustee or the Master Servicer, that the purchase of such Certificates by or
on behalf of such Plan is permissible under applicable law, will not constitute
or result in a non-exempt prohibited transaction under ERISA or Section 4975 of
the Code and will not subject the Company, the Trustee or the Master Servicer to
any obligation in addition to those undertaken in this Agreement. In lieu of
such opinion of counsel, the transferee may provide a certification
substantially to the effect that the purchase of this Certificate by or on
behalf of such Plan is permissible under applicable law, will not subject the
Company, the Trustee or the Master Servicer to any obligation in addition to
those undertaken in this Agreement, and the following statements are correct:
(i) the transferee is an insurance company and the source of funds used to
purchase this Certificate is an "insurance company general account" (as such
term is defined in PTCE 95-60), (ii) the conditions set forth in Sections I and
III of PTCE 95-60

                                      A-2-3

<PAGE>

have been satisfied and (iii) there is no Plan with respect to which the amount
of such general accounts reserves and liabilities for contracts held by or on
behalf of such Plan and all other Plans maintained by the same employer (or any
"affiliate" thereof, as defined in PTCE 95-60) or by the same employee
organization exceed 10% of the total of all reserves and liabilities of such
general account (as determined under PTCE 95-60) as of the date of the
acquisition of this Certificate. Any purchaser of this Certificate (or interest
therein) not issued or transferred as a Definitive Certificate will be deemed to
have made the representation contained in the above certification.

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

          The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement.

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

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

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

          The Certificates are issuable only as registered Certificates without
coupons in Classes and in denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of

                                      A-2-4

<PAGE>

authorized denominations evidencing the same Class and aggregate Percentage
Interest, as requested by the Holder surrendering the same.

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

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

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

          The obligations created by the Agreement in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the Distribution Date on which the Aggregate Certificate Principal Balance
has been reduced to zero, (ii) the maturity or other liquidation of the last
Mortgage Loan subject thereto or the disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (iii) the
purchase by the party designated in the Agreement at a price determined as
provided in the Agreement from REMIC I of all the Mortgage Loans and all
property acquired in respect of such Mortgage Loans. The Agreement permits, but
does not require, the party designated in the Agreement to purchase from REMIC I
all the Mortgage Loans and all property acquired in respect of any Mortgage Loan
at a price determined as provided in the Agreement. The exercise of such right
will effect early retirement of the Certificates; however, such right to
purchase may only be exercised on any Distribution Date when the Pool Principal
Balance is less than 10% of the sum of the Pool Principal Balance as of the
Initial Cut-off Date and the Original Pre-Funded Amount.

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

          Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

the Master Servicer and the Certificate Registrar against any liability that may
result if the transfer, sale, pledge or other disposition is not so exempt or is
not made in accordance with such federal and state laws and this Agreement.

thereof in certain circumstances without the consent of the Holders of any of

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the

State of New York, duly endorsed by, or accompanied by an assignment in the form

property acquired in respect of such Mortgage Loans. The Agreement permits, but
does not require, the party designated in the Agreement to purchase from REMIC I
all the Mortgage Loans and all property acquired in respect of any Mortgage Loan
at a price determined as provided in the Agreement. The exercise of such right
will effect early retirement of the Certificates; however, such right to
purchase may only be exercised on any Distribution Date when the Pool Principal
Balance is less than 10% of the sum of the Pool Principal Balance as of the
Initial Cut-off Date and the Original Pre-Funded Amount.

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

          Distributions on this Certificate will be made either by the Master
Servicer acting on behalf of the Trustee or by a Paying Agent appointed by the

          No transfer, sale, pledge or other disposition of this Class P

disposition is exempt from the registration requirements of the Securities Act
of 1933, as amended (the "1933 Act"), and any applicable state securities laws
or is made in accordance with said Act and laws. Except as otherwise provided in
Section 5.02(d) of the Agreement, in the event that a transfer of this Class P
Certificate is to be made either (i)(A) the Trustee shall require a written
Opinion of Counsel acceptable to and in form and substance satisfactory to the
Trustee and the Company that such transfer may be made pursuant to an exemption,
describing the applicable exemption and the basis therefor, from said Act and
laws or is being made pursuant to said Act and laws, which Opinion of Counsel

any such Certificate by the Company or any Affiliate thereof to an Affiliate of
the Company, and the Trustee shall be entitled to conclusively rely upon a
representation (which, upon the request of the Trustee, shall be written
representation) from the Company of the status, of such transferee as an
Affiliate of the Company or (ii) the prospective transferee of such a
Certificate shall be required to provide the Trustee, the Company and the Master
Servicer with an investment letter substantially in the form of Exhibit G-1

institutional buyer" as defined under Rule 144A, acting for its own account or
the accounts of other "qualified institutional buyers" as defined under Rule
144A, and (B) is aware that the proposed transferor intends to rely on the
exemption from registration requirements under the 1933 Act provided by Rule
144A. The Holder of this Class P Certificate desiring to effect any such
transfer, sale, pledge or other disposition shall, and does hereby agree to,
indemnify the Trustee, the Company, the Master Servicer and the Certificate
Registrar against any liability that may result if the transfer, sale, pledge or
other disposition is not so exempt or is not made in accordance with such
federal and state laws and this Agreement.

          No transfer of this Class P Certificate will be made unless the
Trustee has received an opinion of counsel satisfactory to the Company, the
Trustee and the Master Servicer, which opinion will not be at the expense of the
Company, the Trustee or the Master Servicer, that the purchase of such
Certificates by or on behalf of such Plan is permissible under applicable law,
will not constitute or result in a non-exempt prohibited transaction under ERISA
or Section 4975 of the Code and will not subject the Company, the Trustee or the
Master Servicer to any obligation in addition to those undertaken in this
Agreement.

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

          The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement.

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

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

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee in the City and
State of New York, duly endorsed by, or accompanied by an assignment in the form
below or other written

                                      A-4-4

instrument of transfer in form satisfactory to the Trustee and the Certificate
Registrar duly executed by the Holder hereof or such Holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same Class and aggregate Percentage Interest will
be issued to the designated transferee or transferees.

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

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

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

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

          The obligations created by the Agreement in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the Distribution Date on which the Aggregate Certificate Principal Balance
has been reduced to zero, (ii) the maturity or other liquidation of the last
Mortgage Loan subject thereto or the disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan and (iii) the
purchase by the party designated in the Agreement at a price determined as
provided in the Agreement from REMIC I of all the Mortgage Loans and all
property acquired in respect of such Mortgage Loans. The Agreement permits, but
does not require, the party designated in the Agreement to purchase from REMIC I
all the Mortgage Loans and all property acquired in respect of any Mortgage Loan
at a price determined as provided in the Agreement. The exercise of such right
will effect early retirement of the Certificates; however, such right to
purchase may only be exercised on any Distribution Date when the Pool Principal
Balance is less than 10% of the sum of the Pool Principal Balance as of the
Initial Cut-off Date and the Original Pre-Funded Amount.

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

          Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

registered at the close of business on the last day (or if such last day is not

month immediately preceding the month of such distribution (the "Record Date"),
in an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the amount of required to be distributed to Holders of Class
[R-I][R-II][R-III] Certificates on such Distribution Date.

          Each Holder of this Certificate will be deemed to have agreed to be

United States Person and Permitted Transferee, (iii) any attempted or purported
transfer of any Ownership Interest in this Certificate in violation of such
restrictions will be absolutely null and void and will vest no rights in the
purported transferee, and (iv) if any person other than a United States Person
and a Permitted Transferee acquires any Ownership Interest in this Certificate
in violation of such restrictions, then the Company will have the right, in its
sole discretion and without notice to the Holder of this Certificate, to sell
this Certificate to a purchaser selected by the Company, which purchaser may be
the Company, or any affiliate of the Company, on such terms and conditions as
the Company may choose.

          Notwithstanding the above, the final distribution on this Certificate
will be made after due notice of the pendency of such distribution and only upon
presentation and surrender of this Certificate at the office or agency appointed
by the Trustee for that purpose in the City and State of New York. The Holder of
this Certificate may have additional obligations with respect to this
Certificate, including tax liabilities.

          No transfer, sale, pledge or other disposition of this Class
[R-I][R-II][R-III] Certificate shall be made unless such transfer, sale, pledge
or other disposition is exempt from the registration requirements of the
Securities Act of 1933, as amended (the "1933 Act"), and any applicable state
securities laws or is made in accordance with said Act and laws. Except as
otherwise provided in Section 5.02(d) of the Agreement, in the event that a
transfer of this Class [R- I][R-II][R-III] Certificate is to be made either
(i)(A) the Trustee shall require a written Opinion of Counsel acceptable to and
in form and substance satisfactory to the Trustee and the Company that such
transfer may be made pursuant to an exemption, describing the applicable
exemption and the basis therefor, from said Act and laws or is being made
pursuant to said Act and laws, which Opinion of Counsel shall not be an expense
of the Trustee, the Company or the Master Servicer; provided that such Opinion
of Counsel will not be required in connection with the initial transfer of any
such Certificate by the Company or any Affiliate thereof to an Affiliate of the
Company and (B) the Trustee shall require the transferee to execute a
representation letter, substantially in the form of Exhibit G-1 to the
Agreement, and the Trustee shall require the transferor to execute a
representation letter, substantially in the form of Exhibit H to the Agreement,
each acceptable to and in form and substance satisfactory to the Company and the
Trustee certifying to the Company and the Trustee the facts surrounding such
transfer, which representation letters shall not be an expense of the

                                       B-4

<PAGE>

Trustee, the Company or the Master Servicer; provided, however, that such
representation letters will not be required in connection with any transfer of
any such Certificate by the Company or any Affiliate thereof to an Affiliate of
the Company, and the Trustee shall be entitled to conclusively rely upon a
representation (which, upon the request of the Trustee, shall be written
representation) from the Company of the status, of such transferee as an
Affiliate of the Company or (ii) the prospective transferee of such a
Certificate shall be required to provide the Trustee, the Company and the Master
Servicer with an investment letter substantially in the form of Exhibit G-1
attached to the Agreement, which investment letter shall not be an expense of
the Trustee, the Company, or the Master Servicer, and which investment letter
states that, among other things, such transferee (A) is a "qualified
institutional buyer" as defined under Rule 144A, acting for its own account or
the accounts of other "qualified institutional buyers" as defined under Rule
144A, and (B) is aware that the proposed transferor intends to rely on the
exemption from registration requirements under the 1933 Act provided by Rule
144A. The Holder of this Class [R-I][R-II][R-III] Certificate desiring to effect
any such transfer, sale, pledge or other disposition shall, and does hereby
agree to, indemnify the Trustee, the Company, the Master Servicer and the
Certificate Registrar against any liability that may result if the transfer,
sale, pledge or other disposition is not so exempt or is not made in accordance
with such federal and state laws and this Agreement.

          No transfer of this Class [R-I][R-II][R-III] Certificate will be made
unless the Trustee has received an opinion of counsel satisfactory to the
Company, the Trustee and the Master Servicer, which opinion will not be at the
expense of the Company, the Trustee or the Master Servicer, that the purchase of
such Certificates by or on behalf of such Plan is permissible under applicable
law, will not constitute or result in a non-exempt prohibited transaction under
ERISA or Section 4975 of the Code and will not subject the Company, the Trustee
or the Master Servicer to any obligation in addition to those undertaken in this
Agreement.

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

          The Certificates are limited in right of payment to certain
collections and recoveries respecting the Mortgage Loans, all as more
specifically set forth herein and in the Agreement.

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

          The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Company, the Master Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Company, the Master
Servicer and the Trustee with the consent of the Holders of Certificates
evidencing in the aggregate not less than 66% of the Percentage Interests of
each Class of Certificates affected thereby. Any such consent by the Holder of
this Certificate shall be conclusive and binding on such Holder and upon all
future holders of this Certificate and of any Certificate

                                       B-5

<PAGE>

issued upon the transfer hereof or in exchange herefor or in lieu hereof whether
or not notation of such consent is made thereon. The Agreement also permits the
amendment thereof in certain circumstances without the consent of the Holders of
any of the Certificates and, in certain additional circumstances, without the
consent of the Holders of certain Classes of Certificates.

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

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

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

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

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

          The obligations created by the Agreement in respect of the
Certificates and the Trust Fund created thereby shall terminate upon the payment
to Certificateholders of all amounts held by or on behalf of the Trustee and
required to be paid to them pursuant to the Agreement following the earlier of
(i) the Distribution Date on which the Aggregate Certificate Principal Balance
has been reduced to zero, (ii) the maturity or other liquidation of the last
Mortgage Loan subject thereto or the disposition of all property acquired upon
foreclosure or deed in lieu of foreclosure of any Mortgage Loan, and (iii) the
purchase by the party designated in the Agreement at a price determined as
provided in the Agreement from REMIC I of all the Mortgage Loans and all
property acquired in respect of such Mortgage Loans. The Agreement permits, but
does not require, the party designated in the Agreement to purchase from REMIC I
all the Mortgage Loans and all property acquired in respect of any Mortgage Loan
at a price determined as provided in the Agreement. The exercise of such right
will effect early retirement of the Certificates; however, such right to
purchase may only

                                       B-6

<PAGE>

be exercised on any Distribution Date when the Pool Principal Balance is less
than 10% of the sum of the Pool Principal Balance as of the Initial Cut-off Date
and the Original Pre-Funded Amount.

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

          Unless the certificate of authentication hereon has been executed by
the Certificate Registrar, by manual signature, this Certificate shall not be
entitled to any benefit under the Agreement or be valid for any purpose.

                                       B-7

          IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly
executed.

foregoing (other than an instrumentality all of the activities of which are
subject to tax and, except for the Federal Home Loan Mortgage Corporation, a
majority of whose board of directors is not selected by any such governmental
entity) or any foreign government, international organization or any agency or
instrumentality of such foreign government or organization, any rural electric
or telephone cooperative, or any organization (other than certain farmers'
cooperatives) that is generally exempt from federal income tax unless such
organization is subject to the tax on unrelated business taxable income).

          3. That the Owner is aware (i) of the tax that would be imposed on
transfers of Class [R-I][R-II][R-III] Certificates to disqualified organizations
under the Code, that applies to all transfers of Class [R-I][R-II][R-III]
Certificates after March 31, 1988; (ii) that such tax would be on the
transferor, or, if such transfer is through an agent (which person includes a
broker, nominee or middleman) for a disqualified organization, on the agent;
(iii) that the person otherwise liable for the tax shall be relieved of
liability for the tax if the transferee furnishes to such person an affidavit
that the transferee is not a disqualified organization and, at the time of
transfer, such person does not have actual knowledge that the affidavit is
false; and (iv) that the Class [R-I][R-II][R-III] Certificates may be
"noneconomic residual interests" within the meaning of Treasury regulations
promulgated pursuant to the Code and that the transferor of a noneconomic
residual interest will remain liable for any taxes due with respect to the
income on such residual interest, unless no significant purpose of the transfer
was to impede the assessment or collection of tax.

<PAGE>

          4. That the Owner is aware of the tax imposed on a "pass-through
entity" holding Class [R-I][R-II][R-III] Certificates if at any time during the
taxable year of the pass-through entity a disqualified organization is the
record holder of an interest in such entity. (For this purpose, a "pass through
entity" includes a regulated investment company, a real estate investment trust
or common trust fund, a partnership, trust or estate, and certain cooperatives.)

          5. That the Owner is aware that the Trustee will not register the
transfer of any Class [R-I][R-II][R-III] Certificates unless the transferee, or
the transferee's agent, delivers to it an affidavit and agreement, among other
things, in substantially the same form as this affidavit and agreement. The
Owner expressly agrees that it will not consummate any such transfer if it knows
or believes that any of the representations contained in such affidavit and
agreement are false.

          6. That the Owner has reviewed the restrictions set forth on the face
of the Class [R- I][R-II][R-III] Certificates and the provisions of Section
5.02(f) of the Pooling and Servicing Agreement under which the Class R
Certificates were issued (in particular, clause (iii)(A) and (iii)(B) of Section
5.02(f) which authorize the Trustee to deliver payments to a person other than
the Owner and negotiate a mandatory sale by the Trustee in the event the Owner
holds such Certificates in violation of Section 5.02(f)). The Owner expressly
agrees to be bound by and to comply with such restrictions and provisions.

          7. That the Owner consents to any additional restrictions or
arrangements that shall be deemed necessary upon advice of counsel to constitute
a reasonable arrangement to ensure that the Class [R-I][R-II][R-III]
Certificates will only be owned, directly or indirectly, by an Owner that is not
a disqualified organization.

          8. The Owner's Taxpayer Identification Number is _______________.

          9. This affidavit and agreement relates only to the Class
[R-I][R-II][R-III] Certificates held by the Owner and not to any other holder of
the Class [R-I][R-II][R-III] Certificates. The Owner understands that the
liabilities described herein relate only to the Class [R-I][R-II][R-III]
Certificates.

          10. That no purpose of the Owner relating to the transfer of any of
the Class [R-I][R- II][R-III] Certificates by the Owner is or will be to impede
the assessment or collection of any tax.

          11. That the Owner has no present knowledge or expectation that it
will be unable to pay any United States taxes owed by it so long as any of the
Certificates remain outstanding. In this regard, the Owner hereby represents to
and for the benefit of the person from whom it acquired the Class
[R-I][R-II][R-III] Certificate that the Owner intends to pay taxes associated
with holding such Class R Certificate as they become due, fully understanding
that it may incur tax liabilities in excess of any cash flows generated by the
Class [R-I][R-II][R-III] Certificate.

          12. That the Owner has no present knowledge or expectation that it
will become insolvent or subject to a bankruptcy proceeding for so long as any
of the Class [R-I][R-II][R-III] Certificates remain outstanding.

                                      F-1-2

<PAGE>

          13. The Owner is a citizen or resident of the United States, a
corporation, partnership or other entity created or organized in, or under the
laws of, the United States or any political subdivision thereof (except, in the
case of a partnership, to the extent provided in regulations) or an estate whose
income is subject to United States federal income tax regardless of its source,
or a trust if a court within the United States is able to exercise primary
supervision over the administration of the trust and one or more such United
States Persons have the authority to control all substantial decisions of the
trust. To the extent prescribed in regulations by the Secretary of the Treasury,
which have not yet been issued, a trust which was in existence on August 20,
1996 (other than a trust treated as owned by the grantor under subpart E of part
I of subchapter J of chapter 1 of the Code), and which was treated as a United
States person on August 20, 1996 may elect to continue to be treated as a United
States person notwithstanding the previous sentence.

          14. Either (a) or (b) is satisfied, as marked below:

               a. Purchaser is not any employee benefit plan subject to the
          Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
          or the Internal Revenue Code of 1986 (the "Code"), a Person acting,
          directly or indirectly, on behalf of any such plan or any Person
          acquiring such Certificates with "plan assets" of a Plan within the
          meaning of the Department of Labor regulation promulgated at 29 C.F.R.
          ss.2510.3-101; or

               b. Purchaser will provide the Trustee, the Company and the Master
          Servicer with an opinion of counsel, satisfactory to the Trustee, the
          Company and the Master Servicer, to the effect that the purchase and
          holding of a Certificate by or on behalf of the Purchaser is
          permissible under applicable law, will not constitute or result in a
          prohibited transaction under Section 406 of ERISA or Section 4975 of
          the Code (or comparable provisions of any subsequent enactments) and
          will not subject the Trustee, the Company or the Master Servicer to
          any obligation or liability (including liabilities under ERISA or
          Section 4975 of the Code) in addition to those undertaken in the
          Pooling and Servicing Agreement, which opinion of counsel shall not be
          an expense of the Trustee, the Company or the Master Servicer.

                                      F-1-3

<PAGE>

          15. The Purchaser is not a non-United States person or an electing
large partnership within the meaning of section 775(a) of the Code.

          16. The Owner of the Class R-III Certificate, hereby agrees that in
the event that the Trust Fund created by the Pooling and Servicing Agreement is
terminated pursuant to Section 9.01 thereof, the undersigned shall assign and
transfer to the Holders of the Class CE Certificates any amounts in excess of
par received in connection with such termination. Accordingly, in the event of
such termination, the Trustee is hereby authorized to withhold any such amounts
in excess of par and to pay such amounts directly to the Holders of the Class CE
Certificates. This agreement shall bind and be enforceable against any
successor, transferee or assigned of the undersigned in the Class R-III
Certificate. In connection with any transfer of the Class R-III Certificate, the
Owner shall obtain an agreement substantially similar to this clause from any
subsequent owner.

                                            Very truly yours,

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

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
__________________ (the "Seller") to ______________________________________ (the
"Purchaser") of ___% Percentage Interest of WMC Mortgage Pass-Through
Certificates, Series 2000-A, Class [R-I][R-II][R-III] (the "Certificates"),
pursuant to Section 5.02 of the Pooling and Servicing Agreement (the "Pooling
and Servicing Agreement"), dated as of April 1, 2000, among WMC Secured Assets
Corp., as company (the "Company"), WMC Mortgage Corp., as master servicer, and
Bank One, National Association, as trustee (the "Trustee"). All terms used
herein and not otherwise defined shall have the meanings set forth in the
Pooling and Servicing Agreement. The Seller hereby certifies, represents and
warrants to, and covenants with, the Company and the Trustee that:

          1. No purpose of the Seller relating to the transfer of the
Certificate by the Seller to the Purchaser is or will be to impede the
assessment or collection of any tax.

          2. The Seller understands that the Purchaser has delivered to the
Trustee and the Master Servicer a transfer affidavit and agreement in the form
attached to the Pooling and Servicing Agreement as Exhibit F-1. The Seller does
not know or believe that any representation contained therein is false.

          3. The Seller, at the time of the transfer, has conducted a reasonable
investigation of the financial condition of the Purchaser as contemplated by
Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result of that
investigation, the Seller has determined that the Purchaser has historically
paid its debts as they become due and has found no significant evidence to
indicate that the Purchaser will not continue to pay its debts as they become
due in the future. The Seller understands that the transfer of a Class
[R-I][R-II][R-III] Certificate may not be respected for United

<PAGE>

States income tax purposes (and the Seller may continue to be liable for United
States income taxes associated therewith) unless the Seller has conducted such
an investigation.

          4. The Seller has no actual knowledge that the proposed Transferee is
not both a United States Person and a Permitted Transferee.

                                            Very truly yours,

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

Ladies and Gentlemen:

          _________________________ (the "Purchaser") intends to purchase from
___________________________ (the "Seller") ___% Percentage Interest of WMC
Mortgage Pass- Through Certificates, Series 2000-A, Class ___ (the
"Certificates"), issued pursuant to the Pooling and Servicing Agreement (the
"Pooling and Servicing Agreement"), dated as of April 1, 2000 among WMC Secured
Assets Corp., as company (the "Company"), WMC Mortgage Corp., as master
servicer, and Bank One, National Association, as trustee (the "Trustee"). All
terms used herein and not otherwise defined shall have the meanings set forth in
the Pooling and Servicing Agreement. The Purchaser hereby certifies, represents
and warrants to, and covenants with, the Company and the Trustee that:

          1. The Purchaser understands that (a) the Certificates have not been
     and will not be registered or qualified under the Securities Act of 1933,
     as amended (the "Act") or any state securities law, (b) the Company is not
     required to so register or qualify the Certificates, (c) the Certificates
     may be resold only if registered and qualified pursuant to the provisions
     of the Act or any state securities law, or if an exemption from such
     registration and qualification is available, (d) the Pooling and Servicing
     Agreement contains restrictions regarding the transfer of the Certificates
     and (e) the Certificates will bear a legend to the foregoing effect.

          2. The Purchaser is acquiring the Certificates for its own account for
     investment only and not with a view to or for sale in connection with any
     distribution thereof in any manner that would violate the Act or any
     applicable state securities laws.

<PAGE>

          3. The Purchaser is (a) a substantial, sophisticated institutional
     investor having such knowledge and experience in financial and business
     matters, and, in particular, in such matters related to securities similar
     to the Certificates, such that it is capable of evaluating the merits and
     risks of investment in the Certificates, (b) able to bear the economic
     risks of such an investment and (c) an "accredited investor" within the
     meaning of Rule 501(a) promulgated pursuant to the Act.

          4. The Purchaser has been furnished with, and has had an opportunity
     to review (a) a copy of the Prospectus Supplement, dated
     ___________________, 20__, to the Prospectus, dated ___________, _____
     (collectively, the "Prospectus") relating to the Certificates (b) a copy of
     the Pooling and Servicing Agreement and (c) such other information
     concerning the Certificates, the Mortgage Loans and the Company as has been
     requested by the Purchaser from the Company or the Seller and is relevant
     to the Purchaser's decision to purchase the Certificates. The Purchaser has
     had any questions arising from such review answered by the Company or the
     Seller to the satisfaction of the Purchaser. [If the Purchaser did not
     purchase the Certificates from the Seller in connection with the initial
     distribution of the Certificates and was provided with a copy of the
     Prospectus relating to the original sale (the "Original Sale") of the
     Certificates by the Company, the Purchaser acknowledges that such
     Prospectus was provided to it by the Seller, that the Prospectus was
     prepared by the Company solely for use in connection with the Original Sale
     and the Company did not participate in or facilitate in any way the
     purchase of the Certificates by the Purchaser from the Seller, and the
     Purchaser agrees that it will look solely to the Seller and not to the
     Company with respect to any damage, liability, claim or expense arising out
     of, resulting from or in connection with (a) error or omission, or alleged
     error or omission, contained in the Prospectus, or (b) any information,
     development or event arising after the date of the Prospectus.

          5. The Purchaser has not and will not nor has it authorized or will it
     authorize any person to (a) offer, pledge, sell, dispose of or otherwise
     transfer any Certificate, any interest in any Certificate or any other
     similar security to any person in any manner, (b) solicit any offer to buy
     or to accept a pledge, disposition of other transfer of any Certificate,
     any interest in any Certificate or any other similar security from any
     person in any manner, (c) otherwise approach or negotiate with respect to
     any Certificate, any interest in any Certificate or any other similar
     security with any person in any manner, (d) make any general solicitation
     by means of general advertising or in any other manner or (e) take any
     other action, that (as to any of (a) through (e) above) would constitute a
     distribution of any Certificate under the Act, that would render the
     disposition of any Certificate a violation of Section 5 of the Act or any
     state securities law, or that would require registration or qualification
     pursuant thereto. The Purchaser will not sell or otherwise transfer any of
     the Certificates, except in compliance with the provisions of the Pooling
     and Servicing Agreement.

          6. The Purchaser represents that either (a) or (b) is satisfied, as

          applicable law, will not constitute or result in a prohibited
          transaction under Section 406 of ERISA or Section 4975 of the Code (or
          comparable provisions of any subsequent enactments) and will not
          subject the Trustee, the Company or the Master Servicer to any

        3.2 Product Development, Clinical Research, Regulatory Matters and
Technical Marketing Support.

               (a) Ongoing Product Development and Clinical Research. In
accordance with the Development Plan and subject to the guidance of the Joint
Operating Committee, Ista shall conduct, at its expense and in a timely manner,
all product development, pre-clinical studies and clinical research in support
of FDA, EMEA and other regulatory approvals of the Product, as Ista and Allergan

herein. Ista shall promptly provide to Allergan copies of all material
correspondence received from, and written summaries of material telephone
conversations with, the FDA and other regulatory agencies and EMEA relating to

withheld or delayed. Ista shall give Allergan reasonable advance notice of any
meetings or telephone conferences with representatives of the FDA or other
regulatory agencies relating to the prosecution of the regulatory approvals in
order to allow Allergan an opportunity to attend any such meeting or participate
in such telephone. Any disagreement between the parties shall be referred to the
Joint Operating Committee for resolution.

               (c) Regulatory Approvals Outside the United States and the
European Community. Allergan may, at its expense, apply for and obtain
regulatory approvals of the Product in such countries outside the United States
and the European Community as it deems appropriate in light of the market
potential of the Product, taking into account the competitiveness of the
marketplace, the proprietary position of the Product, the regulatory structure
involved, the profitability of the Product and other relevant factors. In
carrying out its regulatory activities Allergan shall consult with Ista, through

of material telephone conversations with, regulatory agencies relating to the
prosecution of the regulatory approvals, (ii) provide to Ista for approval,
which approval shall not be unreasonably withheld or delayed, filings or
correspondence to be made by Allergan, and (iii) give Ista reasonable advance
notice of any meetings or telephone conferences with representatives of the
regulatory agencies relating to the prosecution of the regulatory approvals in
order to allow Ista to attend such meetings or participate in such telephone
conversations. At Allergan's election, any of such regulatory approvals shall be
owned by Allergan. Ista shall reasonably cooperate with Allergan in obtaining
such approvals and shall supply such information and reports it has possession
of in support of the filings for such regulatory approvals. Any disagreement
between the parties shall be referred to the Joint Operating Committee for
resolution.

               (d) Additional Development. If Allergan desires preclinical or
clinical studies in addition to that set forth in this Section 3.2 and the
Development Plan for expanded label indications for the Product within the
Field, then Allergan shall notify Ista in writing and include a preliminary
preclinical or clinical plan. Through the Joint Operating Committee, the parties
will determine whether or not to proceed with such work and the allocation of
such work and the expenses therefor. In the absence of a mutual agreement,
either party may conduct such work at its expense, and the other party shall
reasonably cooperate to the extent such cooperation does cause such party to
incur any material additional expenses.

               (e) Data. Ista shall maintain records in sufficient detail and in
good scientific manner appropriate for patent and regulatory purposes and shall
properly reflect all work done and results achieved in the performance of the

Affiliate knows or has reason to believe shall use or sell such product in the
Territory for use in the Field; (ii) any product which may be legally used as a
substitute for the Product for use in the Field in the Territory, nor shall they

knows or has reason to believe shall use or sell such product in the Territory
for use in the Field; or (iii) Hyaluronidase bulk substance to any person or
entity (other than Allergan or an Affiliate of Allergan) which Ista or any of

of this Agreement, Allergan and its Affiliates shall not, directly or
indirectly, market or sell any product for the treatment of vitreous hemorrhage
or any product containing Hyaluronidase for the treatment of diabetic
retinopathy, other than the Product. The parties agree that Ista's "Keratase"
and Cornealplasty products (the names of which may be changed pending FDA
approval) are expressly excluded from this provision, provided that such
products are not approved for administration by intravitreal injection, are not
sold with an equivalent Hyaluronidase unit dose and delivery volume as the
Product, are contraindicated for intravitreal injection and are not sold to any
person or entity (other than Allergan of an Affiliate of Allergan) which Ista or

distribution and sale of Product, Ista hereby grants to Allergan and its
Affiliates an exclusive, royalty-free license, with the right to sublicense,
during the term of this Agreement and subject to Section 5.6, to use the Ista
Trademark(s) in the Territory on all labels, advertisements, promotional
materials and literature for the Product.

        5.2 Acknowledgement. Allergan acknowledges that: (i) the Ista
Trademark(s) are owned exclusively by Ista; (ii) that Allergan has no right,
title or interest in and to the Ista Trademark(s), except the rights conferred

Trademark(s) inures to the benefit of Ista.

Trademark(s), at its own expense, in those countries listed in Exhibit 5.3,
including the preparation and recordation of registered user agreements and/or
licenses necessary or reasonably deemed necessary by Allergan in order to comply
with local laws.

        5.4 Use of Trademark(s). The Products shall bear the trademark
Vitrase(R) for distribution and sale (i) within the United States and Canada

the use by any Third Party of the Ista Trademark(s) or any trademark(s) similar

unfair competition. Ista shall have the right to decide whether or not to bring
proceedings against Third Parties. Such proceedings shall be at the expense of
Ista. Allergan shall cooperate fully with Ista to whatever extent is deemed
reasonably necessary by Ista to prosecute such action. In the event that Ista

received for such damages except that Allergan shall be entitled to
reimbursement of its costs, expenses, and attorneys' fees attributable to such
action (or in proportionate amounts thereof should Ista recover an insufficient
amount for both parties' such costs and expenses). Ista shall not settle or
compromise any suit for infringement without the express approval of Allergan,
such approval not to be unreasonably withheld. In the event Ista decides not to
prosecute, and Allergan reasonably determines that the failure to prosecute
would adversely affect the rights of Allergan under this Agreement, Allergan
shall have the right, but not the obligation, to prosecute such action at its
own expense. Ista shall cooperate fully with Allergan to whatever extent is
deemed reasonably necessary by Allergan to prosecute such action. In the event
that Allergan recovers its damages from prosecution of such action, Allergan
shall retain amounts received for such damages except that Ista shall be
entitled to reimbursement of its costs, expenses, and attorneys' fees
attributable to such action (or in proportionate amounts thereof should Allergan
recover an insufficient amount for both parties' such costs and expenses).

6. ROYALTIES, PROFIT SPLIT.

        6.1 Royalties on Net Sales Outside the United States.

               (a) Initial Royalty Rate. With respect to sales of Product inside
the Territory but outside the United States, Allergan shall pay Ista a royalty
of [*] of Net Sales of Product, subject to adjustment as set forth in this
Section 6.1, less the cost of Product for sale outside the United States
purchased by Allergan from Ista pursuant to the Supply Agreement. The credit for
cost of Product purchased by Allergan from Ista pursuant to this Section 6.1(a)
shall be applied in the calendar quarter in which such purchases were made. To
the extent any such credits exceed the royalty due for such quarter, such excess
shall be carried forward to successive calendar quarters until fully utilized

               (b) Adjustments for Proof of Concept, Sales Levels. If Proof of
Concept for Proliferative Diabetic Retinopathy is not achieved by December 31,
2003, the royalty rate in Section 6.1 (a) shall be adjusted to [*] of Net Sales
for sales invoiced after December 31, 2003. Notwithstanding the foregoing, in
the event that either (i) Proof of Concept for Proliferative Diabetic
Retinopathy is achieved, or (ii) Net Sales outside the United States exceed [*]
in any calendar year, then commencing at the beginning of the first calendar
quarter after the achievement of (i) or (ii), the royalty rate in Section 6.1(a)
shall be adjusted to [*] of Net Sales.

               (c) Adjustments for Patent and Competitive Matters. The royalties
in this Section 6.1 shall be subject to a reduction of [*] with respect to Net
Sales in countries during which time there is both [*].

        6.2 Profit Split in United States. The parties shall share equally the
Net Profits in the United States by periodic payment of Profit Payments to Ista
by Allergan. "Net Profits" shall be defined as Net Sales less Manufacturing
Expenses less Marketing and Distribution Expenses for the Product in the United
States. The Profit Payment shall be one-half ( 1/2) of such Net Profits. For
purposes of such calculation Net Profits will be calculated consistent with the
following definitions.

               (a) Net Sales shall have the meaning set forth in Section 1.19
above.

               (b) Manufacturing Expenses shall mean, (i) if the Product is
being purchased by Allergan from Ista pursuant to the Supply Agreement, the
purchase price as set forth therein, as periodically adjusted therein, or (ii)
if the Product is being purchased from a Third Party or manufactured by
Allergan, the then applicable purchase price set forth in the Supply Agreement,
as periodically adjusted therein.

               (c) Marketing and Distribution Expenses shall include the costs
defined below. To the extent that such costs are not discretely identifiable,
Allergan and Ista will aggregate such costs in accordance with its standard
procedures, which will be allocated to the Product consistent with each party's
standard cost allocation procedures.

*Certain information on this page has been omitted and filed
 separately with the Commission. Confidential treatment has
 been requested with respect to the omitted portions.

                                       10

                    (i) Product specific marketing expense incurred for
physician training, direct advertising, films, samples, exhibits, clinical
conference aids, peer promotion activities, marketing research and other direct
out-of-pocket costs normally included as marketing expenses by Allergan's
accounting procedures.

                    (ii) Direct costs, including salaries and employment
benefits for Allergan's Product manager(s) and field sales force properly
allocated to the sale of the Product.

                    (iii) Direct costs, including salaries and employment
benefits for Ista medical marketing liaison personnel properly allocated to the
sale of the Product.

                    (iv) A reasonable allocation of overhead costs computed as a
mutually agreed percentage of such costs and directly related to the
commercialization of the Product.

                    (v) Direct out-of-pocket costs for distribution, transport
and storage of the Product.

                    (viii) Any other costs or expenses incurred which are
incidental to the marketing or distribution of the Product which are designated
as marketing and distribution expenses by the Joint Operating Committee.

        6.3 To the extent Manufacturing Expenses and Marketing and Distribution
Expenses exceed Net Sales in any quarter (resulting in negative "Net Profits"),
such excess shall be carried forward and used in the calculation of Net Profits
for the subsequent quarter or quarters, until such excess has been fully used.

        6.4 Reports, Exchange Rates. During the term of this Agreement and while
Royalties or Profit Payments are payable hereunder, Allergan shall furnish to
Ista a written quarterly report showing, on a country by country basis: (i) the
Net Sales during such quarter and the calculation thereof; (ii) the Royalties
and Profit Payments payable in United States dollars which shall have accrued in
respect of such Net Sales and the calculation thereof; (iii) withholding taxes,
if any, required by law to be deducted in respect of such sales, as applicable;
and (iv) the exchange rates used in determining the amount of United States
dollars. All amounts payable shall first be calculated in the currency of sale
and then converted on a monthly basis into United States dollars using the rate
of exchange used by Allergan in preparing its quarterly financial reports.
Reports, together with the Royalties and Profit Payments payable for the periods
to which the reports relate shall be due on the sixtieth (60th) day following
the close of each calendar quarter. Allergan shall keep, in accordance with
generally accepted accounting principles consistently applied, complete and
accurate records concerning sales of the Product in the Territory in sufficient
detail to enable the Royalties or Profit Payments payable hereunder to be
determined.

        During the term of this Agreement and while Profit Payments are payable
hereunder, Ista shall furnish to Allergan a written quarterly report showing
Ista's Marketing and Distribution Expenses for such period.

        6.5 Audits.

               (a) Upon the written request of Ista, but not more than once each
calendar year, Allergan shall permit an independent public accountant selected
by Ista and acceptable to Allergan, which acceptance shall not be unreasonably
withheld or delayed, to have access during normal business hours to such of the
records of Allergan as may be reasonably necessary to verify the accuracy of the
royalty and profit reports hereunder in respect of any quarter or quarters year
ending not more than thirty-six (36) months prior to the date of such request.
In the event such accountant concludes that additional Royalties and Profit
Payments were owed during such period, the additional Royalties and Profit
Payments shall be paid within thirty (30) days of the date Ista delivers to
Allergan such accountant's written report so concluding. The fees charged by
such accountant shall be paid by Ista unless the audit discloses that the
Royalties and Profit Payments reported payable by Allergan for the audited
period have been understated by more than ten percent (10%) of the Royalties and
Profit Payments actually payable for such period, in which case Allergan shall
pay the reasonable fees and expenses charged by the accountant. Ista agrees that
all information subject to review under this Section 6.4 is confidential and
that it shall cause its accountant to retain all such information in confidence.

               (b) Upon the written request of Allergan, but not more than once
each calendar year, Ista shall permit an independent public accountant selected
by Allergan and acceptable to Ista, which acceptance shall not be unreasonably
withheld or delayed, to have access during normal business hours to such of the
records of Ista as may be reasonably necessary to verify the accuracy of the
Profit Payment calculations hereunder in respect of any quarter or quarters
ending not more than thirty-six (36) months prior to the date of such request.
In the event such accountant concludes that lower Profit Payments were owed by
Allergan during such period, the difference between the Profit Payments owed by
Allergan and the Profit Payments actually paid by Allergan shall be reimbursed
by Ista within thirty (30) days of the date Allergan delivers to Ista such
accountant's written report so concluding. The fees charged by such accountant
shall be paid by Allergan unless the audit discloses that the various expenses
reported by Ista for purpose of calculating the Profit Payment for the audited
period are overstated by more than ten percent (10%) of the actual expenses for
such period, in which case Ista shall pay the reasonable fees and expenses
charged by the accountant. Allergan agrees that all information subject to
review under this Section 6.4 is confidential and that it shall cause its
accountant to retain all such information in confidence.

        6.6 Payment Terms. Royalties and Profit Payments shown to have accrued
by each periodic report provided for under this Agreement shall be due and
payable on the date such periodic report is due. Payment of Royalties and Profit
Payments in whole or in part may be made in advance of such due date. Royalties
and Profit Payments determined to be owing, and any overpayments to be credited,
with respect to any prior quarter shall be added, or credited, as the case may
be, to the next quarterly payment hereunder.

        6.7 Withholding of Taxes. Any withholding of taxes levied by tax
authorities on the payments hereunder shall be borne by Ista and deducted by
Allergan from the sums otherwise payable by it hereunder for payment to the
proper tax authorities on behalf of Ista. Allergan agrees to cooperate with Ista
in the event Ista claims exemption from such withholding or seeks deductions
under any double taxation or other similar treaty or agreement from time to time
in force, such cooperation to consist of providing receipts of payment of such
withheld tax or other documents reasonably available to Allergan.

                                       12
<PAGE>   15

        6.8 Exchange Controls. Except as hereinafter provided in this Section,
all payments to be made pursuant to this Section 6.7 shall be paid in United
States dollars. If at any time legal restrictions prevent the prompt remittance
of part or all of the Royalties and Profit Payments due hereunder with respect
to any country, payment shall be made through such lawful means or methods as
Allergan may determine. When in any country the law or regulations prohibit both
the transmittal and deposit of royalties on sales in such a country, Royalties
and Profit Payments shall be suspended for as long as such prohibition is in
effect, and as soon as such prohibition ceases to be in effect, all Royalties
and Profit Payments that Allergan or its sublicensees would have been obligated
to transmit or deposit, but for the prohibition, shall forthwith be deposited or
transmitted promptly to the extent allowable, as the case may be, along with
interest accrued thereon to the date of payment.

7. MILESTONES.

        7.1 Milestones Earned. As additional consideration for the license
granted to Allergan hereunder, Allergan shall pay to Ista the following amounts
upon achievement (prior to the expiration of termination of this Agreement) of
each of the applicable milestones:

than the maximum amount to be forgiven by Allergan at such time, then the
payment to Ista will be increased so that the consideration received by Ista for
such Milestone accomplishment equals the total amount shown for that Milestone

        7.2 Single Payment. Each of the foregoing milestone payments shall be
payable one time only, even if such milestones are subsequently met again for
another Product. All payments to be made by Allergan to Ista pursuant to this
Section 7.2 shall be made in United States dollars. Ista shall promptly notify
Allergan in writing of the occurrence of the milestones set forth above. Within
twenty (20) business days after the date of such notice, Allergan shall pay to
Ista by certified or bank check, wire transfer or other means acceptable to
Ista, the milestone payments set forth above.

8. REGULATORY MATTERS.

        8.1 Right of Reference, Regulatory Dossiers in the United States and
Europe. In the United States and Europe, Ista shall prepare, file, maintain and
own Regulatory Dossiers for the Product. Ista hereby grants Allergan a
royalty-free right (and shall so advise applicable regulatory authorities if
required) to reference Ista's or its Controlled Affiliates' and Ista's
Hyaluronidase suppliers' and Approved Third Party Contractors' (as defined in
the Supply Agreement) Regulatory

*Certain information on this page has been omitted and filed

 been requested with respect to the omitted portions.

                                       13
<PAGE>   16

Dossiers and registrations for Hyaluronidase and the Product for the purpose of
enabling Allergan to exercise its rights hereunder with respect to the Products
in the Territory, including certain rights beyond the terms of the Agreement
pursuant to Section 12.5. At the request of Allergan, Ista shall assign all
necessary Regulatory Dossiers relating to the Product outside of the United
States to Allergan and Ista further agrees to execute and deliver such
instruments and take such other actions as Allergan shall reasonably request in
order to carry out this provision, including but not limited to, assignments of
regulatory approvals. For purposes of this Section 8, Europe shall mean those
countries which are participants in the EMEA.

        8.2 Regulatory Dossiers outside the United States and Europe. Outside
the United States and Europe, Ista shall give Allergan the right to prepare,
file, and maintain Regulatory Dossiers for the Product in Allergan's name, and
Allergan shall do so in such countries in which it markets the Product pursuant
to Section 9. Ista shall also give Allergan ownership rights to such Regulatory
Dossiers, subject to the terms and conditions of this Agreement and the
following: (i) Allergan shall, at Ista's request and option, provide Ista with
complete copies of any Regulatory Dossiers filed by or under authority of
Allergan; (ii) subject to Section 4.3, Allergan shall promptly provide Ista or
its designees with the relevant portions of (and make available for copying by
Ista or its designees), and the right to cross-reference, any Regulatory
Dossiers held in the name of Allergan (or that of its Affiliate or sublicensee)
reasonably necessary or useful to enable Ista or its designees to market
products other than Product in the applicable country, and Allergan shall
execute, acknowledge and deliver such further instruments, and shall do all such
other acts, all as promptly as possible, which may be necessary or appropriate
to effectuate such right in each such country and to otherwise make fully
available to Ista and its designees the benefits of such Regulatory Dossiers for
purposes of exercising any right not exclusively granted to Allergan hereunder,
upon the request of Ista.

        8.3 Product Recalls. In the event (a) any government authority issues a
request, directive or order that the Product be recalled, or (b) a court of
competent jurisdiction orders such a recall, or (c) Allergan and Ista, after
consultation with each other, determine that the Product should be recalled, or
(d) either Allergan or Ista, after consultation with each other, if legally
required to make such recall, does so, the parties shall take all appropriate
corrective actions, and shall cooperate in the investigations surrounding the
recall. Allergan shall handle notification of customers and return of Product
from customers. The owner of the relevant regulatory approval shall handle all
communications and requests with regulatory agencies regarding any recalls. If
such recall results from any cause or event arising from a sole responsibility
of Ista as set forth in this Agreement or in the Supply Agreement or is solely
attributable to Ista, Ista shall be responsible for all expenses of the recall
and Allergan may deduct any such expenses borne by Allergan from any payment due
to Ista under this Agreement. If such recall results from a sole responsibility
of Allergan as set forth in this Agreement or in the Supply Agreement or is
solely attributable to Allergan, Allergan shall be responsible for the expenses
of recall and shall reimburse Ista for expenses incurred by Ista for such
recall. In the event that the recall results from any cause(s) or event(s)
arising from a joint responsibility of the parties or partially from a
responsibility of Ista and partially from a responsibility of Allergan, Ista and
Allergan shall be jointly responsible for expenses of the recall in proportion
to each such party's proximate fault with respect to the recall. If the parties
are unable to agree on the allocation of such fault, then such dispute shall be
subject to the dispute resolution provisions of Section 15. For the purpose of
this Agreement, the expenses of recall shall include, without limitation, the
expenses of notification and destruction or return of the recalled Product, cost
for the Product recalled, legal expenses, inventory write-offs and penalties
resulting from Third Party contracts, but shall not include goodwill, lost
profits or other similar intangible or speculative claims.

                                       14
<PAGE>   17

        8.4 Adverse Event Reports. Each of Ista and Allergan shall report to the
other potentially serious or unexpected adverse events (including adverse drug
experiences, as defined in 21 C.F.R. Section 314.80 or other applicable
regulations ) with respect to the Product of which it becomes aware promptly and
in no event later than five (5) days after initial receipt of the information by
such party. Each such report shall identify lot numbers and customers affected,
if known. Each of Ista and Allergan shall report to the other party summaries of
other adverse events with respect to the Product every twelve (12) months.

9. MARKETING.

        9.1 Marketing Plans. Allergan shall prepare marketing plans for the
United States (the "Marketing Plans"). Such Marketing Plans shall include plans
related to the prelaunch, launch, promotion and sale of the Product. Allergan
shall submit the Marketing Plans at annually to the Joint Operating Committee.
In addition, at least annually Allergan provide marketing strategies and
information on Major Markets other than the United States.

        9.2 Diligence. Allergan shall use reasonable commercial efforts,
consistent with local market, business, regulatory and competitive conditions to
seek Marketing Approval and launch the Product in each country of the Territory
and thereafter to market, promote and distribute such Product in such country.

        9.3 Failure to Commercialize. In the event that Allergan has not made a
First Commercial Sale in a Major Market within twelve (12) months after
Marketing Approval in such Major Market, unless the parties mutually agree not
to market Product in such Major Market, then the license granted in Section 4.1
shall become non-exclusive in such country unless Allergan's failure to make
such a First Commercial Sale results from Ista's failure to supply Product.

        9.4 Product Marking. Product intended for distribution in the U.S. shall
be marked as a product of Allergan, but shall also carry the legend: "Marketed
under license from Ista Pharmaceuticals, Inc." with equal prominence to any
reference to Allergan. Product intended for distribution in the Territory
outside the U.S. shall carry the same legend, but not necessarily with equal
prominence. Ista reserves the right, upon reasonable notice, to specify a
different legend for the Product.

10. PATENTS, IMPROVEMENTS.

        10.1 Prosecution and Maintenance. Ista shall be responsible for and
shall diligently carry out and shall bear all costs (including attorney fees)
for the preparation, filing, prosecution, maintenance, and extensions, if any,
of all patents or patent applications within the Licensed Patents in those
countries in the Territory listed on Appendix 1.15. In addition, Ista shall
promptly advise Allergan of all material correspondence, filings and notices of
action between Ista and the United States Patent and Trademark Office ("PTO")
and equivalent foreign patent offices concerning the Licensed Patents. If Ista
elects not to prepare and file a patent application or discontinues the
prosecution of any patent application or maintenance of any patent within the
Licensed Patents, then Ista shall promptly notify Allergan and supply Allergan
with copies of all written communications with such office. In the event that
Allergan reasonably determines that the failure of Ista to pursue the filing and
prosecution of the patent application would adversely affect the rights of
Allergan under this Agreement, Allergan may, but does not have the obligation
to, file or continue prosecution of such application or maintain such patent at
its own expense. If Allergan so elects, then Ista shall be responsible for the
reasonable costs incurred by Allergan in connection with such filing or

                                       15
<PAGE>   18

prosecution in any country listed in Appendix 1.15, and Allergan may deduct any
such costs borne by Allergan from any payment due to Ista under this Agreement.

        10.2 Improvements. Ista shall promptly notify Allergan of any
Improvements and of any efforts by Ista to patent Improvements in the Territory
including, but not limited to designation of the countries in which any patent
application in respect thereof is to be filed. Any patent application in respect
of such Improvement and any patent issued therefrom shall become part of the
Licensed Patents and Appendix 1.15 shall be modified to reflect the addition to
Licensed Patents. If any Improvement is not patented, it shall become part of
the Licensed Know-How.

        10.3 Enforcement of Patent Rights. If either Allergan or Ista has
knowledge of any infringement or likely infringement of a Licensed Patent or
unauthorized use of Licensed Know-How, then the party having such knowledge
shall promptly inform the other party in writing, and the parties shall promptly
consult with one another regarding the action to be taken. Unless the parties
otherwise mutually agree, Ista shall prosecute such suit, and Allergan shall
cooperate with Ista in the prosecution thereof and Ista shall have the right to
determine the strategy of the prosecution of such suit. Notwithstanding the
foregoing, if Allergan is participating in the prosecution, Allergan shall be
entitled to have input in the strategy of prosecution. Ista shall have the right
to determine the counsel to be retained by the parties in connection with such
action or claim, which counsel shall be reasonably satisfactory to Allergan.
Ista may seek the assistance and participation of Allergan in the action or
claim. If Ista prosecutes such claim without the participation of Allergan, the
costs and expenses incurred in connection with such action or claim shall be
borne by Ista. However, if Allergan participates in the action or claim, the
costs and expenses incurred in connection with such action or claim shall be
shared equally by Ista and Allergan. If Allergan does not participate in the
prosecution of the action or claim, or unless otherwise provided in this Section
10.3, any offer of settlement and any settlement shall be in Ista's discretion,
provided that any offer of settlement or settlement does not conflict with
licenses granted under Section 4. If Allergan participates in the prosecution of
the action or claim, then any offer of settlement and any settlement shall be
subject to the prior approval of both Allergan and Ista. Each party agrees not
to unreasonably withhold its approval of any such settlement. If Allergan does
not participate in the prosecution of the action or claim, any recovery of
damages or other payments received in connection with such action or claim shall
be realized by Ista. If Allergan participates in the prosecution any recovery of
damages or other payments received in connection with such shall be allocated
between and disbursed to Allergan and Ista as follows: (i) first, to reimburse
Allergan and Ista for their respective costs and expenses incurred in connection
with such action, and (ii) the balance of recovery or other payments to be
divided fifty percent (50%) to Allergan and fifty percent (50%) to Ista. In the
event that the recovery of damages is not sufficient to cover costs and expenses
incurred by the parties in connection with such action, each party shall be
reimbursed on a pro rata basis according to each party's percentage of the total
costs and expenses incurred by the parties together.

        10.4 Infringement of Third Party Patent Rights. If a claim or suit is
brought against Allergan alleging (a) infringement of any patent or unauthorized
use of any Licensed Know-How owned by a Third Party by reason of Allergan's
exercise of its licenses hereunder or (b) an interest in any patent under the
Licensed Patents, Allergan shall promptly give written notice to Ista and Ista
shall be responsible for the defense of such claim and bear the cost thereof.
The parties shall furnish each other with reasonable assistance regarding such
claim or suit as may be requested by the other party. Any offer of settlement or
settlement of the claim or suit by one party shall have the prior written
approval of the other party, such approval not to be unreasonably withheld. If
any amounts are paid or payable to a Third Party by Allergan or any damages
and/or costs are awarded against

                                       16
<PAGE>   19

Allergan in such suit, then in the calendar year of payment, such amounts,
damages and costs may be offset against any Royalties due Ista under Section 6
of this Agreement, or Ista may make such payment on behalf of Allergan. For
damages and costs accruing from sales of Product in the United States, Allergan
shall apply such damages and costs as a Marketing and Distribution Expense under
Section 6.2(c) so that the amounts payable are included in the calculation of
Net Profits. Any amounts which Allergan is entitled to credit against Royalties
under this Section 10.4 shall be carried forward until all such amounts have
been credited.

11. REPRESENTATIONS AND WARRANTIES.

        11.1 Ista Representations and Warranties. Ista hereby represents and
warrants that:

               (a) Authority. Ista has the full right, power and corporate

licenses set forth in this Agreement and that there are no outstanding
agreements, assignments or encumbrances in existence inconsistent with the
provisions of this Agreement.

               (b) Ownership, Title. Ista is the sole and exclusive owner or
exclusive licensee of the entire right, title and interest in and to each of the
Licensed Patents, and Ista Trademarks and all of the Licensed Know-How and has

development, or will develop or assist in the development, of the Licensed
Technology, have executed valid assignments of their rights to Ista.

               (c) Litigation. To best of Ista's knowledge as of the Effective
Date, there are no litigation actions, claims or suits by a Third Party
threatened or pending before any court or governmental agency or other tribunal
relating to the Licensed Patents, Ista Trademarks or Licensed Know-How.

               (d) No Third Party Rights. Ista has not authorized (other than as
disclosed in writing to Allergan by way of a disclosure letter on the Effective
Date), and shall not during the term of this Agreement authorize Third Parties
to practice the Licensed Patents or the Licensed Know-How in the Field in the
Territory or otherwise grant rights or licenses to market and sell the Product

inconsistent with the rights granted to Allergan herein

               (e) Validity and Infringement. As of the Effective Date, Ista is
not aware of any prior act or any fact which would cause it to conclude that any

EXPRESSLY DOES NOT WARRANT THAT ANY ISTA PATENT IS VALID OR ENFORCEABLE.

               (f) Product Formulation. To the best of Ista's knowledge as of
the Effective Date (other than as disclosed in writing to Allergan by way of a
disclosure letter on the Effective Date), there are no defects in design or
formulation of the Product which would adversely and unduly affect its
performance or create an unusual and undue risk of injury to person or property
beyond those as may be expected from a pharmaceutical product which has not
received marketing approval in the United States.

               (g) Regulatory Matters. To the best of Ista's knowledge as of the
Effective Date, all of the Regulatory Dossiers are free of any
misrepresentations or omissions on the part of Ista, its Affiliates,

reasonable when viewed within the standards of the industry, and that all
responses of Ista, its Affiliates, predecessors-in-interest or agents to any
inquiries of the FDA were made in good faith.

having jurisdiction over it.

AGREEMENT AND THE SUPPLY AGREEMENT, NEITHER PARTY MAKES ANY REPRESENTATION OR
EXTENDS ANY WARRANTIES OF ANY KIND EITHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE,
NONINFRINGEMENT, OR VALIDITY OF ANY PATENTS ISSUED OR PENDING.

        12.5 Effect of Expiration or Termination of This Agreement Generally.

               (a) Existing Obligations. Expiration of this Agreement for any
reason shall not relieve the Parties of any obligation that accrued prior to

above, Allergan shall have a fully-paid, perpetual, irrevocable license, with
right to sublicense, under the Licensed Technology to manufacture, use, market,
distribute, offer to sell, and sell the Product in the Field in such country.
Nothing herein shall obligate Ista to deliver, at such time, any manufacturing
know-how to allow Allergan to exercise its residual rights under this Section
12.5(e).

               (f) Reassignment of Regulatory Dossiers. Upon termination of this
Agreement by Allergan pursuant to Section 12.4 or by Ista pursuant to Section
12.2, in any country in which Ista has assigned the Regulatory Dossier for the
Product to Allergan pursuant to Section 8.1 herein, Allergan shall promptly
assign such Regulatory Dossier back to Ista. In addition, in such event Allergan
shall ensure that all regulatory filings and approvals in other than Ista's name
pursuant to Section 8.2 relating to the Product (to the extent legally
permissible in the relevant country) are promptly assigned to Ista after such
termination of this Agreement. With respect to any Regulatory Dossier held in
the name of a sublicensee of Allergan, Allergan shall cause such sublicensee to
provide Ista with a letter of authorization for the foregoing, in form and
substance reasonably acceptable to Ista, simultaneously with the granting of
rights by Allergan to such sublicensee.

                                       19

Allergan further agrees to execute and deliver such instruments and take such
other actions as Ista shall reasonably request in order to carry out this
provision

        12.6 Allergan's Right to Offset Royalties and Other Payments. In the
event of (i) the bankruptcy of Ista or (ii) a breach by Ista of any of its
representations, warranties or obligations hereunder (including a material
breach by Ista which would entitle Allergan to terminate this Agreement pursuant
to Section 12.2), Allergan shall have the right and option, in addition to all
other remedies at law or under this Agreement, to offset the amount of such
damages and/or costs against any amounts otherwise due to Ista under Section 6
or Section 7.

13. INDEMNIFICATION, INSURANCE

        13.1 By Ista. Ista shall indemnify, defend and hold Allergan, its
directors, employees, agents and representatives harmless from and against all
claims, causes of action, settlement costs (including reasonable attorney fees
and expenses), losses or liabilities of any kind which are asserted by a Third
Party and which (a) involve the registration (in countries for which Ista is
responsible) or use of the Product as a pharmaceutical product or the safety or
efficacy of the Product, including any theory of strict liability in tort or any
other theory of product liability, and which are not otherwise attributable to
any negligent act or omission or willful misconduct on the part of Allergan, its
Affiliates, sublicensees, directors, employees, agents or representatives; or
(b) arise from claims that the Product or its manufacture, use or sale infringes
a patent, trademark or other proprietary right of a Third Party; or (c) arise
from a breach of a representation or warranty in Section 11.1; or (d) arise out
the negligent act or omission or willful misconduct by Ista in the manufacture
of the Product by Ista.

        13.2 By Allergan. Allergan shall indemnify, defend and hold Ista, its
directors, employees, agents and representatives harmless from and against all
claims, causes of action, settlement costs (including reasonable attorney fees
and expenses), losses or liabilities of any kind which; (a) arise from a breach
of a representation or warranty in Section 11.2; or (b) arise from the improper
registration (in countries for which Allergan is responsible), marketing,
handling or distribution of the Product; or (c) arise from claims that the
Product infringes the trademark of a Third Party if the Product is marketed
using a trademark belonging to Allergan pursuant to Section 5.4.

        13.3 Condition of Indemnification. If either party expects to seek
indemnification under this Article, it shall promptly give notice to the
indemnifying party of the basis for such claim of indemnification. If
indemnification is sought as a result of any Third Party claim or suit, such
notice to the indemnifying party shall be within fifteen (15) days after receipt
by the other party of such claim or suit; provided, however, that the failure to
give notice within such time period shall not relieve the indemnifying party of
its obligation to indemnify unless it shall be materially prejudiced by the
failure. Each such party shall cooperate fully with the other party in the
defense of all such claims or suits. No offer of settlement, settlement or
compromise shall be binding on a party hereto without its prior written consent
(which consent shall not be unreasonably withheld) unless such settlement fully
releases the other party without any liability, loss, cost or obligation to such
party.

        13.4 Insurance. Ista shall maintain comprehensive general liability
(CGL) insurance, including broad form contractual liability and product
liability coverages, in an amount of at least five million dollars ($5,000,000)
for bodily injury and property damage. Allergan shall be named as an additional
insured under Ista's CGL policy. Ista shall maintain such insurance during the
term of this Agreement and thereafter for a period of five (5) years. Allergan
shall obtain by the date of the

                                       20
<PAGE>   23

first marketing approval for the Product, at its costs, a comprehensive general
liability insurance policy, including broad form contractual liability and
product liability coverages and shall maintain such insurance for the term of
this Agreement and thereafter for a period of five (5) years. Ista shall be
named as an additional insured under Allergan's CGL policy. Each party upon
request shall provide the other party with a certificate of insurance as
evidence of the requested coverages and shall give the other party at least
thirty (30) days notice of any cancellation, termination or change in such
insurance.

14. CONFIDENTIAL INFORMATION AND PUBLICITY.

        14.1 Due Care. It is recognized by the parties that during the term of
this Agreement, the parties shall exchange Confidential Information pertaining
to their performance hereunder. Each party shall exercise due care to prevent
the disclosure of Confidential Information of the other party.

        14.2 Permitted Disclosures.

               (a) Notwithstanding the above, nothing contained in this
Agreement shall preclude Ista or Allergan from utilizing or disclosing to others
its Confidential Information or utilizing Confidential Information received from
the other party as may required: (i) for regulatory purposes, including
obtaining FDA approvals; (ii) for audit, tax or customs purposes; or (iii) by
law (including disclosure obligations under applicable securities laws), court
or other government order, provided that the party subject to such order
notifies the other party and uses reasonable efforts to obtain a protective
order covering such Confidential Information.

               (b) In addition to the foregoing, Allergan and Ista may disclose
the Confidential Information of the other party, only to such employees or Third
Parties who have a reasonable need for the Confidential Information in the
performance of their services in connection with the matters set forth in this
Agreement or otherwise within the scope of the licenses set forth in Article 5
and Section 3.9; who are informed of the confidential nature of the Confidential
Information; and who are bound not to disclose such Confidential Information.

        14.3 Other Agreements. The parties have entered into a Confidential
Disclosure Agreement dated February 8, 1999 ("CDA"). The CDA shall remain in
full force and effect as to its confidentiality requirements for the terms
specified therein. However, on and after the Effective Date of this Agreement,
all subject matter conveyed or covered under this Agreement shall be governed in
all respects by the confidentiality provisions contained in this Article 14. The
obligations of the parties set forth in this Article 14 shall apply during the
term hereof and for a period of five (5) years after the date of early
termination or expiration of this Agreement or any extension thereof.

        14.4 Publicity. The parties agree that upon the execution of this
Agreement, a press release approved by both parties shall be issued. Except for
such press release and periodic disclosures by Ista or Allergan required by law
or regulation or in the ordinary course of its SEC filings, neither party shall
(a) originate any publicity, news release or other public announcement, written
or oral, whether to the public press, stockholders or otherwise, relating to
this Agreement, any amendment hereto or performance hereunder, or (b) use the
name of the other in any publicity, news release or other public announcement,
except (i) with the prior written consent of the other party, or (ii) as
required by law, in which case the originating party shall give to the other
party at least ten (10) days prior notice of such proposed disclosure to
complete a review in order to offer comments and modifications. Consistent with
applicable law, the other party shall have the right to

                                       21
<PAGE>   24

request reasonable changes to the disclosure to protect its interests. In all
other cases, the originating party shall give the consenting party at least ten
(10) days to complete a review in order to offer comments, modifications or to
give such consent. The party required to give consent shall endeavor to respond
in less than ten (10) days if practicable.

15. MISCELLANEOUS.

        15.1 Force Majeure. Neither party shall be held liable or responsible to
the other party nor be deemed to have defaulted under or breached this Agreement
for failure or delay in fulfilling or performing any term of this Agreement when
such failure or delay is caused by or results from causes beyond the reasonable
control of the affected party, including but not limited to fire, floods,
embargoes, war, acts of war (whether war is declared or not), insurrections,
riots, civil commotions, strikes, lockouts or other labor disturbances, acts of
God or acts, omissions or delays in acting by any governmental authority or the
other party; provided, however, that the party so affected shall use reasonable
commercial efforts to avoid or remove such causes of nonperformance, and shall
continue to perform hereunder with reasonable dispatch whenever such causes are
removed. Either party shall provide the other party with prompt written notice
of any delay or failure to perform that occurs by reason of force majeure. The
parties shall mutually seek a resolution of the delay or the failure to perform
as noted above.

        15.2 Assignment. This Agreement may not be assigned or otherwise
transferred by either party without the prior written consent of the other
party, which consent shall not be unreasonably withheld or delayed; provided,
however, that each of the parties may, without such consent, assign this
Agreement and its rights and obligations hereunder to its Affiliates or in
connection with the transfer or sale of all or substantially all of its
business, or in the event of its merger or consolidation or change in control or
similar transaction (which shall be deemed an assignment). Notwithstanding the
foregoing, Allergan can sell, transfer or assign its rights under the Agreement
to any Third Party as part of a sale of substantially all of its assets related
to its ophthalmic pharmaceutical business. Any purported assignment in violation
of the preceding sentences shall be void. Any permitted assignee shall assume
all obligations of its assignor under this Agreement in writing.

        15.3 Severability. Each party hereby agrees that it does not intend to
violate any public policy, statutory or common laws, rules, regulations, treaty
or decision of any government agency or executive body thereof of any country or
community or association of countries. Should one or more provisions of this
Agreement be or become invalid, the parties hereto shall substitute, by mutual
consent, valid provisions for such invalid provisions which valid provisions in
their economic effect are sufficiently similar to the invalid provisions that it
can be reasonably assumed that the parties would have entered into this
Agreement with such valid provisions. In case such valid provisions cannot be
agreed upon, the invalidity of one or several provisions of this Agreement shall
not affect the validity of this Agreement as a whole, unless the invalid
provisions are of such essential importance to this Agreement that it is to be
reasonably assumed that the parties would not have entered into this Agreement
without the invalid provisions.

        15.4 Notices. Any consent, notice or report required or permitted to be
given or made under this Agreement by one of the parties hereto to the other
shall be in writing, delivered personally or by facsimile (and promptly
confirmed by personal delivery or courier) or international courier, postage
prepaid (where applicable), addressed to such other party at its address
indicated below, or to such other address as the addressee shall have last
furnished in writing to the addressor and shall be effective upon the earlier of
receipt by the addressee or the second business day after dispatch by recognized
international courier.

applicable time periods under this Agreement shall be tolled. In the event such

period, the parties shall submit their dispute to binding arbitration before a
single arbitrator in Orange County, California, such arbitration to be conducted

then in effect. The arbitrator may permit limited discovery as he or she deems

with respect to the subject matter hereof. In the event of any conflict or
