income tax purposes. The Class A Certificates (as defined herein) will represent
ownership of "regular interests" in the REMIC, and the Class R Certificates will
constitute the sole Class of "residual interest" in the REMIC for purposes of
the REMIC Provisions (as defined herein) under federal income tax law.

Original Security Balance (as defined herein), maturity date, initial ratings

security agreement within the meaning of Articles 8 and 9 of the New York
Uniform Commercial Code and the Uniform Commercial Code of any other applicable
jurisdiction; (b) the conveyance provided for in this Section shall be deemed to
be (1) a grant by the Depositor to the Trustee of a security interest in all of
the Depositor's right (including the power to convey title thereto), title and
interest, whether now owned or hereafter acquired, in and to (A) the Mortgage
Loans, including the Mortgage Notes, the Mortgages, any related insurance
policies and all other documents in the related Mortgage Files, (B) all amounts

voluntary or involuntary, of the foregoing into cash, instruments, securities or
other property, including without limitation all amounts from time to time held
or invested in the Certificate Account or the Collection Account, whether in the
form of cash, instruments, securities or other property and (2) an assignment by
the Depositor to the Trustee of any security interest in any and all of the
Seller's right (including the power to convey title thereto), title and
interest, whether now owned or hereafter acquired, in and to the property
described in the foregoing clauses (1)(A) through (C) granted by the Seller to
the Depositor pursuant to the Purchase Agreement; (c) the possession by the
Trustee or its agent of Mortgage Notes and such other items of property as
constitute instruments, money, negotiable documents or chattel paper shall be
deemed to be "possession by the secured party" or possession by a purchaser or a
person designated by such secured party, for purposes of perfecting the security
interest pursuant to the New York Uniform Commercial Code and the Uniform
Commercial Code of any other applicable jurisdiction (including, without
limitation, Sections 9-305, 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
acknowledgments, receipts or confirmations from, financial intermediaries,
bailees or agents (as applicable) of the Trustee for the purpose of perfecting
such security interest under applicable law. The Depositor and, at the
Depositor'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, such security interest would be deemed to be a perfected
security interest of first priority under applicable law and will be maintained
as such throughout the term of the Agreement.

the Trustee will appoint a custodian (a "Custodian") to hold the Mortgage Files
in trust for the benefit of all present and future Certificateholders and the
Certificate Insurer; provided, however, that the custodian so appointed shall in
no event be the Depositor or the Servicer or any Person known to a Responsible
Officer of the Trustee to be an Affiliate of the Depositor or the Servicer. The
Trustee hereby appoints ___________________ as the initial Custodian.

          (d) The Custodian shall afford the Depositor, the Certificate Insurer

Mortgage File which is not executed, has not been received, is unrelated to the
Mortgage Loan identified in the related Mortgage Loan Schedule, or does not
conform to the requirements of Section 2.03 or the description thereof as set
forth in the related Mortgage Loan Schedule, the Trustee or the Certificate
Insurer, as applicable, shall promptly so notify the Servicer, the Seller, the
Certificate Insurer and the Trustee. In performing any such review, the Trustee
may conclusively rely on the Seller as to the purported genuineness of any such
document and any signature thereon. It is understood that the scope of the
Trustee's review of the Mortgage Files is limited solely to confirming that the
documents listed in Section 2.03 have been executed and received and relate to
the Mortgage Files identified in the related Mortgage Loan Schedule and such
documents conform to the standard set forth in clause (ii) of the paragraph

period, request that the Seller (i) substitute in lieu of such Mortgage Loan a
Qualified Substitute Mortgage Loan in the manner and subject to the conditions
set forth in Section 3.03 or (ii) purchase such Mortgage Loan on the next
succeeding Servicer Remittance Date (but not later than 90 days after the
discovery of such defect) at a purchase price equal to the actual stated
principal balance of such Mortgage Loan as of the date of purchase, plus all
accrued and unpaid interest on such principal balance computed at the Mortgage
Interest Rate, plus the amount of any unpaid Servicing Fees, unreimbursed
Periodic Advances and unreimbursed Servicing Advances made by the Servicer with
respect to such Mortgage Loan, which purchase price shall be deposited in the
Collection Account on the same Business Day, after deducting therefrom any
amounts received in respect of such repurchased Mortgage Loan or Loans and being
held in the Collection Account for 

                                       28

 
future distribution to the extent such amounts have not yet been applied to
principal or interest on such Mortgage Loan (the "Loan Repurchase Price"). 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 Certificateholders or the Trustee on behalf of
Certificateholders. In addition, it is understood and agreed that the Depositor
has assigned to the Trustee all of its rights under the Purchase Agreement and
the right to enforce any remedy against the Seller as provided in Section 2.05
of the Purchase Agreement. For purposes of calculating the amount the Servicer
is required to remit on the Servicer Remittance Date following such repurchase
or substitution, any Loan Repurchase Price or Substitution Adjustment that is
paid and deposited in the related Collection Account as provided above shall be
deemed to have been deposited in the related Collection Account in the Due
Period preceding such Servicer Remittance Date.

          (c) Upon receipt by the Trustee of a certification of a Servicing
Officer of such substitution or purchase and, in the case of a substitution,
upon receipt of the related Mortgage File, and the deposit of the amounts
described above in the Collection Account (which certification shall be in the
form of Exhibit H hereto), the Trustee shall release to the Servicer for release
to the Seller the related Mortgage File and shall execute, without recourse, and
deliver such instruments of transfer furnished by the Seller as may be necessary
to transfer such Mortgage Loan to the Seller. The Trustee shall notify the
Certificate Insurer if the Seller fails to repurchase or substitute for a
Mortgage Loan in accordance with the foregoing.

          Section 2.05 EXECUTION OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the delivery of the Mortgage Files
relating thereto to it and, concurrently with such delivery, has executed,
authenticated and delivered to or upon the order of the Depositor, in exchange
for the Mortgage Loans, the Mortgage Files and the other assets included in the
definition of Trust Fund, Certificates duly authenticated by the Trustee in
Authorized Denominations evidencing the entire ownership of the Trust Fund.

          Section 2.06 FURTHER ACTION EVIDENCING ASSIGNMENTS. (a) The Depositor
agrees that, from time to time, at the Seller's expense, the Depositor shall
cause the Seller promptly to execute and deliver all further instruments and
documents, and take all further action, that may be necessary or appropriate, or
that the Servicer or the Trustee may reasonably request, in order to perfect,
protect or more fully evidence the transfer of ownership of the Trust Fund or to
enable the Trustee to exercise or enforce any of its rights hereunder. Without
limiting the generality of the foregoing, the Depositor will, upon the request
of the Servicer or of the Trustee execute and file (or cause to be executed and
filed) such real estate filings, financing or continuation statements, or
amendments thereto or assignments thereof, and such other instruments or
notices, as may be necessary or appropriate.

          (b) The Depositor hereby grants to the Servicer and the Trustee powers
of attorney to execute all documents on its behalf under this Agreement and the
Purchase Agreement as may be necessary or desirable to effectuate the foregoing.

          Section 2.07[RESERVED].

          Section 2.08CONVEYANCE OF THE SUBSEQUENT MORTGAGE LOANS.

          (a) Subject to the conditions set forth in paragraph (b) below in
consideration of the Trustee's delivery on the related Subsequent Transfer Dates
to or upon the order of the Depositor of all or a portion of the balance of
funds in the Pre-Funding Account, the Depositor shall on any Subsequent Transfer
Date sell, transfer, assign, set over and convey without recourse to the Trust
Fund but subject to the other terms and provisions of this Agreement all of the
right, title and interest of the Depositor in and to (i) the Subsequent Mortgage
Loans identified on the Mortgage Loan Schedule attached to the related
Subsequent Transfer Instrument delivered by the Depositor on such Subsequent
Transfer Date, (ii) principal due and interest accruing on the Subsequent
Mortgage Loans after the related Subsequent Cut-off Date and (iii) all items
with respect to such Subsequent Mortgage Loans to be delivered pursuant to
Section 2.03 above and the other items in the related Mortgage Files; provided,
however, that the Depositor reserves and retains all right, title and interest
in and to principal received and interest accruing on the Subsequent Mortgage
Loans prior to the related Subsequent Cut-off Date. The transfer to the Trustee
by the Depositor of the Subsequent Mortgage Loans identified on the Mortgage
Loan Schedule shall be absolute and is intended by the Depositor, the Servicer,
the Trustee and the Certificateholders to constitute and to be treated as a sale
of the Subsequent Mortgage Loans by the Depositor to the Trust Fund.  The
related Mortgage File for each Subsequent Mortgage Loan shall be delivered to
the Trustee two Business Days prior to the Subsequent Transfer Date.

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

          (b) The Depositor shall transfer to the Trustee the Subsequent
Mortgage Loans and the other property and rights related thereto described in
Section 2.08 (a) above, and the Trustee shall release funds from the related
Pre-Funding Account, only upon the satisfaction of each of the following
conditions on or prior to the related Subsequent Transfer Date:

          (i) the Depositor shall have provided the Trustee and the Certificate
     Insurer with a timely Addition Notice and shall have provided any
     information reasonably requested by the Trustee or the Certificate Insurer
     with respect to the Subsequent Mortgage Loans;

          (ii) the Depositor shall have delivered to the Trustee a duly executed
     Subsequent Transfer Instrument, which shall include a Mortgage Loan
     Schedule, listing the Subsequent Mortgage Loans;

          (iii) as of each Subsequent Transfer Date, the Depositor shall not be
     insolvent nor shall it have been made insolvent by such transfer nor shall
     it be aware of any pending insolvency;

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

                                       30

 
          (v) the Pre-Funding Period shall not have terminated;

     Subsequent Transfer Instrument;

          (vii) the Certificate Insurer shall have delivered to the Trustee an
     Officer's Certificate confirming that the Subsequent Mortgage Loans conform
     to the representations and warranties of Section 5.07 of the Insurance
     Agreement;

          (viii) the Depositor shall have delivered to the Trustee Opinions of
     Counsel addressed to the Certificate Insurer, the Rating Agencies and the

     substantially in the form of the Opinions of Counsel delivered to the
     Certificate Insurer and the Trustee on the Closing Date regarding certain
     bankruptcy, corporate and tax matters; and

          (ix) the Trustee shall have delivered to the Certificate Insurer and
     the Depositor an Opinion of Counsel addressed to the Depositor, the Rating
     Agencies and the Certificate Insurer with respect to the Subsequent
     Transfer Instrument substantially in the form of the Opinion of Counsel
     delivered to the Certificate Insurer and the Depositor on the Closing Date
     regarding certain corporate matters relating to the Trustee.

          (c) The obligation of the Trust Fund to purchase a Subsequent Mortgage
Loan on any Subsequent Transfer Date is subject to the following representations
and warranties of the Depositor with respect to such Subsequent Mortgage Loan
being satisfied: (i) such Subsequent Mortgage Loan may not be 30 or more days
contractually delinquent as of the related Subsequent Cut-off Date; (ii) the

in excess of $______; and (d) not have a concentration of second lien Mortgage
Loans in excess of ____%, by aggregate principal balance of the related Mortgage

Loans with characteristics varying from those set forth above may be purchased
by the Trust Fund; provided, however, that the addition of such Mortgage Loans
will not materially affect the aggregate characteristics of the Mortgage Loans.

                                       31

 
          (d) Within five Business Days after the end of the Pre-Funding Period,
the Depositor shall deliver to each Rating Agency a copy of the updated Mortgage
Loan Schedule including the Subsequent Mortgage Loans in electronic format.

                                       32

          It is understood and agreed that the representations, warranties and
covenants set forth in this Section 3.02 shall survive delivery of the
respective Mortgage Files to the Trustee or to a custodian, as the case may be,
and shall inure to the benefit of the Trustee, the Certificateholders and the
Certificate Insurer.

          Section 3.03 PURCHASE AND SUBSTITUTION. (a) It is understood and
agreed that the representations and warranties set forth in Sections ____ and
____ of the Purchase Agreement shall survive delivery of the Certificates to the
Certificateholders. Pursuant to the Purchase Agreement, with respect to any
representation or warranty contained in Sections ____ and ____ of the Purchase
Agreement that is made to the best of the Seller's knowledge, if it is
discovered by the Servicer, the Trustee, the Certificate Insurer or any
Certificateholder that the substance of such representation and warranty was
inaccurate as of the Closing Date and such inaccuracy materially and adversely
affects the value of the related Mortgage Loan, then notwithstanding the
Seller's lack of knowledge with respect to the inaccuracy at the time the
representation or warranty was made, such inaccuracy shall be deemed a breach of
the applicable representation or warranty. Upon discovery by the Seller, the
Servicer, the Trustee or the Certificate Insurer of a breach of any of such
representations and warranties which materially and adversely affects the value
of the Mortgage Loans or the interest of the Certificateholders or the
Certificate Insurer, or which materially and adversely affects the interests of
the Certificate Insurer or the Certificateholders in the related Mortgage Loan
in the case of a representation and warranty relating to a particular Mortgage
Loan (notwithstanding that such representation and warranty was made to the
Seller's best knowledge), the party discovering such breach shall give prompt
written notice to the others. Subject to the last paragraph of this Section
3.03, within 60 days of the earlier of its discovery or its receipt of notice of
any breach of a representation or warranty, pursuant to the Purchase Agreement,
the Seller shall be required to (a) promptly cure such breach in all material
respects, or (b) purchase such Mortgage Loan on the next succeeding Servicer
Remittance Date, in the manner and at the price specified in Section 2.04(b), or
(c) remove such Mortgage Loan from the Trust Fund (in which case it shall become
a Deleted Mortgage Loan) and substitute one or more Qualified Substitute
Mortgage Loans; provided, that, such substitution is effected not later than the
date which is two years after the Startup Day or at such later date, if the
Trustee and the Certificate Insurer receive an Opinion of Counsel to the effect
set forth below in this Section. Pursuant to the Purchase Agreement, any such
substitution shall be 

                                       35

 
accompanied by payment by the Seller of the Substitution Adjustment, if any, to
be deposited in the Collection Account.

          (b) As to any Deleted Mortgage Loan for which the Seller substitutes a
Qualified Substitute Mortgage Loan or Loans, the Seller shall be required
pursuant to the Purchase Agreement to effect such substitution by delivering to
the Trustee a certification in the form attached hereto as Exhibit H, executed
by a Servicing Officer and the documents described in Sections 2.03(a)(i)-(vi)
for such Qualified Substitute Mortgage Loan or Loans.

          (c) The Servicer shall deposit in the Collection Account all payments
received in connection with such Qualified Substitute Mortgage Loan or Loans
after the date of such substitution. Monthly Payments received with respect to
Qualified Substitute Mortgage Loans on or before the date of substitution will
be retained by the Seller. The Trust Fund will own all payments received on the
Deleted Mortgage Loan on or before the date of substitution, and the Seller
shall thereafter be entitled to retain all amounts subsequently received in
respect of such Deleted Mortgage Loan. The Servicer shall give written notice to
the Trustee and the Certificate Insurer that such substitution has taken place
and shall amend the Mortgage Loan Schedule to reflect the removal of such
Deleted Mortgage Loan from the terms of this Agreement and the substitution of
the Qualified Substitute Mortgage Loan. Upon such substitution, such Qualified
Substitute Mortgage Loan or Loans shall be subject to the terms of this
Agreement in all respects.

          (d) It is understood and agreed that the obligations of the Seller set
forth in Sections ____ and ____ of the Purchase Agreement to cure, purchase or
substitute for a defective Mortgage Loan as provided in Sections ____ and ____
constitute the sole remedies of the Trustee, the Certificate Insurer and the
Certificateholders respecting a breach of the representations and warranties of
the Seller set forth in Sections ____ and ____ of the Purchase Agreement. In
addition, it is understood and agreed that the Depositor has assigned to the
Trustee all of its rights under the Purchase Agreement and the right to enforce
any remedy against the Seller as provided in Section 3.04 of the Purchase
Agreement. The Trustee shall give prompt written notice to the Certificate
Insurer and the Rating Agencies of any repurchase or substitution made pursuant
to this Section 3.03 or Section 2.04(b).

          (e) Upon discovery by the Servicer, the Trustee, the Certificate
Insurer or any Certificateholder that any Mortgage Loan does not constitute a
Qualified Mortgage, the party discovering such fact shall promptly (and in any
event within five days of the discovery) give written notice thereof to the
other parties. In connection therewith, pursuant to the Purchase Agreement, the
Seller shall be required to repurchase or substitute a Qualified Substitute
Mortgage Loan for the affected Mortgage Loan within 90 days of the earlier of
such discovery by any of the foregoing parties, or the Trustee's or the Seller's
receipt of notice, in the same manner as it would a Mortgage Loan for a breach
of representation or warranty contained in Section ____ or ____ of the Purchase
Agreement. The Trustee shall reconvey to the Seller the Mortgage Loan to be
released pursuant hereto in the same manner, and on the same terms and
conditions, as it would a Mortgage Loan repurchased for breach of a
representation or warranty contained in Section ____ or ____ of the Purchase
Agreement.

                                       36

 
                                   ARTICLE IV

                                THE CERTIFICATES

          Section 4.01 THE CERTIFICATES. The Certificates shall be substantially
in the forms annexed hereto as Exhibits B-1 and B-2. The Certificates shall be
issued in Authorized Denominations only. All Certificates shall be executed by
manual or facsimile signature on behalf of the Trustee by an authorized officer
and authenticated by the manual or facsimile signature of an authorized officer.
Certificates bearing the signatures of individuals who were at the time of the
execution of the Certificates the authorized 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 delivery of such Certificates or did not hold
such offices at the date of such Certificates. All Certificates issued hereunder
shall be dated the date of their authentication.

          Section 4.02 REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.
(a) The Trustee, as registrar, shall cause to be kept a register (the
"Certificate Register") in which, subject to such reasonable regulations as it
may prescribe, the Trustee shall provide for the registration of Certificates
and the registration of transfer of Certificates. The Trustee is hereby
appointed registrar for the purpose of registering Certificates and transfers of
Certificates as herein provided. The Certificate Insurer shall be entitled to
inspect and verify the Certificate Register and the records of the Trustee
relating to the Certificates during normal business hours upon reasonable
notice.

          (b) All Certificates issued upon any registration of transfer or
exchange of Certificates shall be valid evidence of the same ownership interests
in the Trust Fund and entitled to the same benefits under this Agreement as the
Certificates surrendered upon such registration of transfer or exchange.

          (c) Every Certificate presented or surrendered for registration of
transfer or exchange shall be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
Holder thereof or his attorney duly authorized in writing.

          (d) No service charge shall be made to a Holder for any registration
of transfer or exchange of Certificates, but the Trustee may require payment of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of
Certificates; any other expenses in connection with such transfer or exchange
shall be an expense of the Trust Fund.

          (e) It is intended that the Class A Certificates be registered so as
to participate in a global book-entry system with the Depository, as set forth
herein.  Each Class of Class A Certificates shall, except as otherwise provided
in the next paragraph, be initially issued in the form of a single fully
registered Class A Certificate of such Class with a denomination equal to the
Original Security Balance of such Class. Upon initial issuance, the ownership of
each such Class A Certificate shall be registered in the Certificate Register in
the name of Cede & Co., or any successor thereto, as nominee for the Depository.
The Depositor and the Trustee are hereby authorized to execute and deliver the
Representation Letter with the Depository. With 

                                       37

 
respect to Class A Certificates registered in the Certificate Register in the
name of Cede & Co., as nominee of the Depository, the Depositor, the Seller, the
Servicer, the Trustee and the Certificate Insurer shall have no responsibility
or obligation to Direct or Indirect Participants or beneficial owners for which
the Depository holds Class A Certificates from time to time as a Depository.
Without limiting the immediately preceding sentence, the Depositor, the Seller,
the Servicer, the Trustee and the Certificate Insurer shall have no
responsibility or obligation with respect to (i) the accuracy of the records of
the Depository, Cede & Co., or any Direct or Indirect Participant with respect
to any Ownership Interest, (ii) the delivery to any Direct or Indirect
Participant or any other Person, other than a Certificateholder, of any notice
with respect to the Class A Certificates or (iii) the payment to any Direct or
Indirect Participant or any other Person, other than a Certificateholder, of any
amount with respect to any distribution of principal or interest on the Class A
Certificates. No Person other than a Certificateholder shall receive a
certificate evidencing such Class A Certificate. Upon delivery by the Depository
to the Trustee of written notice to the effect that the Depository has
determined to substitute a new nominee in place of Cede & Co., and subject to
the provisions hereof with respect to the payment of interest by the mailing of
checks or drafts to the Certificateholders appearing as Certificateholders at
the close of business on a Record Date, the name "Cede & Co." in this Agreement
shall refer to such new nominee of the Depository.

          (f) In the event that (i) the Depository or the Depositor advises the
Trustee in writing that the Depository is no longer willing or able to discharge
properly its responsibilities as nominee and depository with respect to the
Class A Certificates and the Depositor or the Depository is unable to locate a
qualified successor or (ii) the Depositor at its sole option elects to terminate
the book-entry system through the Depository, the Class A Certificates shall no
longer be restricted to being registered in the Certificate Register in the name
of Cede & Co. (or a successor nominee) as nominee of the Depository. At that
time, the Depositor may determine that the Class A Certificates shall be
registered in the name of and deposited with a successor depository operating a
global book-entry system, as may be acceptable to the Depositor, or such
depository's agent or designee but, if the Depositor does not select such
alternative global book-entry system, then the Class A Certificates may be
registered in whatever name or names Certificateholders transferring Class A
Certificates shall designate, in accordance with the provisions hereof;
provided, however, that any such reregistration shall be at the expense of the
Depositor.

          (g) Notwithstanding any other provision of this Agreement to the
contrary, so long as any Class A Certificate is registered in the name of Cede &
Co., as nominee of the Depository, all distributions of principal or interest on
such Class A Certificates as the case may be and all notices with respect to
such Class A Certificates as the case may be shall be made and given,
respectively, in the manner provided in the Representation Letter.

          (h) Except as provided in Section 4.02(i), no transfer, sale, pledge
or other disposition of a Class R Certificate shall be made unless such
transfer, sale, pledge or other disposition is exempt from the registration
requirements of the Securities Act of 1933, as amended (the "Act"), and any
applicable state securities laws or is made in accordance with said Act and
laws. In the event that a transfer of a Class R Certificate is to be made under
this Section 4.02(h), (i) the Depositor may direct the Trustee to require an
Opinion of Counsel acceptable to and in form and substance satisfactory to the
Trustee and the Depositor that such transfer shall be made pursuant to an
exemption, describing the applicable exemption and the 

                                       38

 
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
Depositor or the Servicer, provided that such Opinion of Counsel will not be
required in connection with the initial transfer of any such Certificate by the
Depositor or any affiliate thereof, to a non-affiliate of the Depositor and (ii)
the Trustee shall require the transferee to execute a representation letter,
substantially in the form of Exhibit O hereto, and the Trustee shall require the
transferor to execute a representation letter, substantially in the form of
Exhibit P hereto, each acceptable to and in form and substance satisfactory to
the Depositor and the Trustee certifying to the Depositor and the Trustee the
facts surrounding such transfer, which representation letters shall not be an
expense of the Trustee, the Depositor or the Servicer, provided that such
representation letter will not be required in connection with any transfer of
any such Certificate by the Depositor to an affiliate of the Depositor. Any such
Certificateholder desiring to effect such transfer shall, and does hereby agree
to, indemnify the Trustee, the Depositor and the Servicer against any liability
that may result if the transfer is not so exempt or is not made in accordance
with such applicable federal and state laws.

          (i) Transfers of Certificates may be made in accordance with this
Section 4.02(i) if the prospective transferee of a Certificate provides the
Trustee and the Depositor with an investment letter substantially in the form of
Exhibit Q attached hereto, which investment letter shall not be an expense of
the Trustee, the Depositor or the  Servicer, and which investment letter states
that, among other things, such transferee is a "qualified institutional buyer"
as defined under Rule 144A. Such transfers shall be deemed to have complied with
the requirements of Section 4.02(h) hereof; provided, however, that no Transfer
of any of the Certificates may be made pursuant to this Section 4.02(i) by the
Depositor. Any such Certificateholder desiring to effect such transfer shall,
and does hereby agree to, indemnify the Trustee, the Depositor and the  Servicer
against any liability that may result if the transfer is not so exempt or is not
made in accordance with such applicable federal and state laws.

          (j) 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 appointed the Depositor or its designee as its attorney-in-fact
to negotiate the terms of any mandatory sale under clause (8) below and to
execute all instruments of transfer and to do all other things necessary in
connection with any such sale, and the rights of each Person acquiring any
Ownership Interest in a Class R Certificate are expressly subject to the
following provisions:

          (1) 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.

          (2) 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, an
affidavit and agreement (a "Transfer Affidavit and Agreement") attached hereto
as Exhibit I from the proposed Transferee, in form and substance satisfactory to
the Trustee, representing and warranting, among other things, that such
Transferee is a Permitted Transferee, that it is not acquiring its Ownership

                                       39

 
Interest in the Class R Certificate that is the subject of the proposed Transfer
as a nominee, trustee or agent for any Person that 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 4.02(j) and agrees to be bound by them.

          (3) Notwithstanding the delivery of a Transfer Affidavit and Agreement
by a proposed Transferee under clause (2) above, if the Trustee 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.

          (4) 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 (attached hereto as Exhibit J) to the Trustee stating
that, among other things, it has no actual knowledge that such other Person is
not a Permitted Transferee.

          (5) The Trustee will register the Transfer of any Class R Certificate
only if it shall have received the Transfer Affidavit and Agreement and all of
such other documents as shall have been reasonably required by the Trustee as a
condition to such registration. In addition, no Transfer of a Class R
Certificate shall be made unless the Trustee shall have received a
representation letter from the Transferee of such Certificate to the effect that
such Transferee is not a Disqualified Non-United States Person and is not a
Disqualified Organization. Transfers of the Class R Certificates to Disqualified
Non-United States Persons and Disqualified Organizations are prohibited.

          (6) Any attempted or purported transfer of any Ownership Interest in a
Class R Certificate in violation of the provisions of this Section 4.02 shall be
absolutely null and void and shall vest no rights in the purported transferee.
If any purported transferee shall become a Holder of a Class R Certificate in
violation of the provisions of this Section 4.02, then the last preceding
Permitted Transferee shall be restored to all rights as Holder thereof
retroactive to the date of registration of transfer of such Class R Certificate.
The Trustee shall notify the Depositor upon receipt of written notice or
discovery by a Responsible Officer that the registration of transfer of a Class
R Certificate was not in fact permitted by this Section 4.02. Knowledge shall
not be imputed to the Trustee with respect to an impermissible transfer in the
absence of such a written notice or discovery by a Responsible Officer. 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
4.02 or for making any payments due on such Certificate to the Holder thereof or
taking any other action with respect to such Holder under the provisions of this
Agreement so long as the transfer was registered after receipt of the related
Transfer Affidavit and Transfer Certificate. The Trustee shall be entitled, but
not obligated to recover from any Holder of a Class R Certificate that was in
fact not a Permitted Transferee at the time it became a Holder or, at such
subsequent time as it became other than a Permitted Transferee, all payments
made on such Class R Certificate at and after either such time. Any such
payments so recovered by the Trustee shall be paid and delivered by the Trustee
to the last preceding Holder of such Certificate.

          (k) The Trustee shall make available to the Internal Revenue Service
and those Persons specified by the REMIC Provisions, all information necessary
to compute any tax imposed (A) as a result of the transfer of an ownership
interest in a Class R Certificate to any 

                                       40

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

          (l) No transfer of a Class R Certificate or any interest therein shall
be made to any employee benefit plan or other retirement arrangement, including
individual retirement accounts and annuities, Keogh plans and collective
investment funds and separate accounts in which such plans, accounts or
arrangements are invested, that is subject to the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), or the Code (each, a "Plan"), unless
the prospective transferee of such Class R Certificate provides the  Servicer
and the Trustee with a certification of facts and, at the prospective
transferee's expense, an Opinion of Counsel which establish to the satisfaction
of the Servicer and the Trustee that such transfer will not result in a
violation of Section 406 of ERISA or Section 4975 of the Code or cause the
Servicer or the Trustee to be deemed a fiduciary of such Plan or result in the
imposition of an excise tax under Section 4975 of the Code. In the absence of
their having received the certification of facts or Opinion of Counsel
contemplated by the preceding sentence, the Trustee and the Servicer shall
require the prospective transferee of any Class R Certificate to certify in the
form of Exhibit O or Exhibit Q that (A) it is neither (i) a Plan nor (ii) a
Person who is directly or indirectly purchasing a Class R Certificate on behalf
of, as named fiduciary of, as trustee of, or with assets, of a Plan and (B) all
funds used by such transferee to purchase such Certificates will be funds held
by it in its general account which it reasonably believes do not constitute
"plan assets" of any Plan.

          (m) Subject to the restrictions set forth in this Agreement, upon
surrender for registration of transfer of any Certificate at the office or
agency of the Trustee located in New York, New York, the Trustee shall execute,
authenticate and deliver in the name of the designated transferee or
transferees, a new Certificate of the same Class and Percentage Interest and
dated the date of authentication by the Trustee. At the option of the
Certificateholders, Certificates may be exchanged for other Certificates of
Authorized Denominations of a like aggregate Percentage Interest, upon surrender
of the Certificates to be exchanged at such office. Whenever any Certificates
are so surrendered for exchange, the Trustee shall execute, authenticate and
deliver the Certificates which the Certificateholder making the exchange is
entitled to receive. No service charge shall be made for any transfer or
exchange of Certificates, but the Trustee may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of Certificates. All Certificates
surrendered for transfer and exchange shall be cancelled by the Trustee.

          Section 4.03 MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. If (a)
any mutilated Certificate is surrendered to the Trustee, or the Trustee receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (b) 

                                       41

 
there is delivered to the Trustee such security or indemnity as may reasonably
be required by each of them to save each of them harmless, then, in the absence
of notice to the Trustee that such Certificate has been acquired by a bona fide
purchaser, the Trustee shall execute, authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like tenor and Percentage Interest, but bearing a number not
contemporaneously outstanding. Upon the issuance of any new Certificate under
this Section 4.03, the Trustee may require the payment of a sum sufficient to
cover any tax or other governmental charge that may be imposed in relation
thereto and their fees and expenses connected therewith. Any duplicate
Certificate issued pursuant to this Section 4.03 shall constitute complete and
indefeasible evidence of ownership in the Trust Fund, as if originally issued,
whether or not the mutilated, destroyed, lost or stolen Certificate shall be
found at any time.

          Section 4.04 PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate for registration of transfer and subject to the provisions of
Section 4.02 and Article X, the Servicer, the Depositor, the Seller, the
Certificate Insurer and the Trustee may treat the Person in whose name any
Certificate is registered as the owner of such Certificate for the purpose of
receiving remittances pursuant to Section 6.05 and for all other purposes
whatsoever, and the Servicer, the Depositor, the Seller, the Certificate Insurer
and the Trustee shall not be affected by notice to the contrary.

                                       42

 
                                   ARTICLE V

               ADMINISTRATION AND SERVICING OF THE MORTGAGE LOANS

          Section 5.01 APPOINTMENT OF THE SERVICER. (a) ________ agrees to act
as the Servicer and to perform all servicing duties under this Agreement subject
to the terms hereof.

          (b) The Servicer shall service and administer the Mortgage Loans on
behalf of the Trustee and shall have full power and authority, acting alone or
through one or more Subservicers, to do any and all things in connection with
such servicing and administration which it may deem necessary or desirable.
Without limiting the generality of the foregoing, the Servicer may, and is
hereby authorized and empowered by the Trustee to, execute and deliver, on
behalf of itself, the Certificateholders and the Trustee or any of them, any and
all instruments of satisfaction or cancellation, or of partial or full release
or discharge and all other comparable instruments, with respect to the Mortgage
Loans, the insurance policies and accounts related thereto and the properties
subject to the Mortgages. Upon the execution and delivery of this Agreement, and
from time to time as may be required thereafter, the Trustee shall execute for
the Servicer any powers of attorney and such other documents as may be necessary
or appropriate to enable the Servicer to carry out its servicing and
administrative duties hereunder.

          In servicing and administering the Mortgage Loans, the Servicer shall
employ procedures consistent with Accepted Servicing Practices and in a manner
consistent with recovery under any insurance policy required to be maintained by
the Servicer pursuant to this Agreement.

          Costs incurred by the Servicer in effectuating the timely payment of
taxes and assessments on the property securing a Mortgage Note and foreclosure
costs may be added by the Servicer to the amount owing under such Mortgage Note
where the terms of such Mortgage Note so permit; provided, however, that the
addition of any such cost shall not be taken into account for purposes of
calculating the principal amount of the Mortgage Note and Mortgage Loan, the
Monthly Payments on the Mortgage Note and Mortgage Loan or distributions to be
made to Certificateholders. Such costs shall be recoverable by the Servicer
pursuant to Section 5.04.

          (c) Subject to Section 5.12, the Servicer is hereby authorized and
empowered to execute and deliver on behalf of the Trustee and each
Certificateholder, all instruments of satisfaction or cancellation, or of
partial or full release, discharge and all other comparable instruments, with
respect to the Mortgage Loans and with respect to the Mortgaged Properties. If
reasonably required by the Servicer, the Trustee shall execute any powers of
attorney furnished to the Trustee by the Servicer and other documents necessary
or appropriate to enable the Servicer to carry out its servicing and
administrative duties under this Agreement.

          (d) On and after such time as the Trustee receives the resignation of,
or notice of the removal of, the Servicer from its rights and obligations under
this Agreement, and with respect to resignation pursuant to Section 5.24, after
receipt by the Trustee and the Certificate Insurer of the Opinion of Counsel
required pursuant to Section 5.24, the Trustee or its 

                                       43

 
designee approved by the Certificate Insurer (which approval shall not be
unreasonably withheld) shall assume all of the rights and obligations of the
Servicer, subject to Section 7.02 hereof. The Servicer shall, upon request of
the Trustee but at the expense of the Servicer, deliver to the Trustee all
documents and records relating to the Mortgage Loans and an accounting of
amounts collected and held by the Servicer and otherwise use its best efforts to
effect the orderly and efficient transfer of servicing rights and obligations to
the assuming party.

          (e) If the Mortgage relating to a Mortgage Loan did not have a lien
senior on the related Mortgaged Property as of the Cut-Off Date, then the
Servicer, in such capacity, may not consent to the placing of a lien senior to
that of the Mortgage on the related Mortgaged Property. If the Mortgage relating
to a Mortgage Loan had a lien senior to the Mortgage Loan on the related
Mortgaged Property as of the Cut-Off Date, then the Servicer, in such capacity,
may consent to the refinancing of such senior lien; provided that (i) the
resulting Combined Loan-to-Value Ratio of such Mortgage Loan is no higher than
the Combined Loan-to-Value Ratio prior to such refinancing and (ii) the interest
rate for the loan evidencing the refinanced senior lien on the date of such
refinancing is no higher than the interest rate on the loan evidencing the
existing senior lien immediately prior to the date of such refinancing.

          (f) The Servicer shall deliver a list of Servicing Officers to the
Trustee and the Certificate Insurer by the Closing Date.

          Section 5.02 [Reserved]

          Section 5.03 COLLECTION OF CERTAIN MORTGAGE LOAN PAYMENTS; COLLECTION
ACCOUNT. (a) The Servicer shall make reasonable efforts to collect all payments
called for under the terms and provisions of the Mortgage Loans, and shall, to
the extent such procedures shall be consistent with this Agreement and any
applicable primary mortgage insurance policy, follow such collection procedures
as shall constitute Accepted Servicing Practices. Consistent with the foregoing,
the Servicer may in its discretion (i) waive any prepayment charge, assumption
fee, late payment charge or other charge in connection with a Mortgage Loan, and
(ii) arrange a schedule, running for no more than 180 days after the Due Date
for payment of any installment on any Mortgage Note, for the liquidation of
delinquent items. Any provision of this agreement to the contrary
notwithstanding, the Servicer shall not agree to the modification or waiver of
any provision of a Mortgage Loan at a time when such Mortgage Loan is not in
default or such default is not reasonably foreseeable, if such modification or
waiver would be treated as a taxable exchange under Section 1001 of the Code,
unless such exchange would not be considered a "prohibited transaction" under
the REMIC Provisions.

          The Servicer shall establish and maintain in the name of the Trustee
the Collection Account, in trust for the benefit of the Certificateholders and
the Certificate Insurer. The Collection Account shall be established and
maintained as an Eligible Account.

          The Servicer shall deposit in the Collection Account (i) any amounts
representing Monthly Payments on the Mortgage Loans due or to be applied as of a
date after the Cut-off Date, with 

                                       44

 
respect to the Initial Mortgage Loans, or Subsequent Cut-off Date, with respect
to the Subsequent Mortgage Loans, (ii) any amounts representing Monthly Payments
on the Initial Mortgage Loans due or to be applied as of a date on or before the
Cut-off Date (except for any interest accrued prior to the Cut-off Date and
except for any principal received by the Depositor prior to the Cut-off Date the
receipt of which is reflected on the Mortgage Loan Schedule) and (iii)
thereafter, on a daily basis within two Business Days of receipt (except as
otherwise permitted herein), the following payments and collections received or
made by it (other than any amounts in respect of principal of or interest on the
Mortgage Loans which, under clauses (i) and (ii) above, are not required to be
deposited in the Collection Account):

        (i)    all payments received after the Cut-off Date or Subsequent
     Cut-off Date, as applicable on account of principal on the Mortgage Loans
     and all Principal Prepayments in Full, Curtailments and all Net REO
     Proceeds collected after the Cut-off Date or Subsequent Cut-off Date, as
     applicable;

        (ii)   all payments received after the Cut-off Date or Subsequent Cut-
     off Date, as applicable on account of interest on the Mortgage Loans (other
     than payments of interest that accrued on each Mortgage Loan up to and
     including the Cut-off Date or Subsequent Cut-off Date, as applicable);

        (iii)  all Net Liquidation Proceeds;

        (iv)   all Insurance Proceeds;

        (v)    all Released Mortgaged Property Proceeds;

        (vi)   any amounts payable in connection with the repurchase of any
     Mortgage Loan and the amount of any Substitution Adjustment pursuant to
     Sections 2.04 and 3.03; and

        (vii)  any amount expressly required to be deposited in the Collection
     Account in accordance with certain provisions of this Agreement, including,
     without limitation Sections 2.04(b), 2.04(c), 3.03(a), 3.03(c), 5.06, 5.07
     and 5.18 of this Agreement;

        provided, however, that the Servicer shall be entitled, at its
election, either (a) to withhold and to pay to itself the applicable Servicing
Fee from any payment on account of interest or other recovery (including Net REO
Proceeds) as received and prior to deposit of such payments in the Collection
Account or (b) to withdraw the applicable Servicing Fee from the Collection
Account after the entire payment or recovery has been deposited therein;
provided, further, that with respect to any payment of interest received by the
Master Servicer in respect of a Mortgage Loan (whether paid by the Mortgagor or
received as Liquidation Proceeds, Insurance Proceeds or otherwise) which is less
than the full amount of interest then due with respect to such Mortgage Loan,
only that portion of such payment that bears the same relationship to the total
amount of such payment of interest as the rate used to determine the Servicing
Fee bears to the Mortgage Interest Rate borne by such Mortgage Loan shall be
allocated to the Servicing Fee with respect to such Mortgage Loan. All other
amounts shall be deposited in the Collection Account not later than the second
Business Day following the day of receipt and posting by the Servicer.

                                       45

 
          The Servicer may invest the funds in the Collection Account only in
Permitted Investments. No Permitted Investment shall be sold or disposed of at a
gain prior to maturity unless the Servicer has obtained an Opinion of Counsel
(at the Servicer's expense) that such sale or disposition will not cause the
Trust Fund to be subject to the tax on income from prohibited transactions
imposed by Section 860F(a)(1) of the Code, otherwise subject the Trust Fund to
tax or cause the Trust Fund to fail to qualify as a REMIC. All income (other
than any gain from a sale or disposition of the type referred to in the
preceding sentence) realized from any such Permitted Investment shall be for the
benefit of the Servicer as additional servicing compensation. The amount of any
losses incurred in respect of any such investments shall be deposited in the
Collection Account by the Servicer out of its own funds immediately as realized.

          The foregoing requirements for deposit in the Collection Account shall
be exclusive, it being understood and agreed that, without limiting the
generality of the foregoing, payments in the nature of those described in the
last paragraph of Section 5.14 and payments in the nature of prepayment charges,
late payment charges or assumption fees need not be deposited by the Servicer in
the Collection Account. If the Servicer deposits in the Collection Account any
amount not required to be deposited therein, it may at any time withdraw such
amount from the Collection Account, any provision herein to the contrary
notwithstanding. All funds deposited by the Servicer in the Collection Account
shall be held in the Collection Account for the account of the Trustee in trust
for the Certificateholders until disbursed in accordance with Section 6.01 or
withdrawn in accordance with Section 5.04.

          (b) Prior to the time of their required deposit in the Collection
Account, all amounts required to be deposited therein may be deposited in an
account in the name of Servicer, provided that such account is an Eligible
Account. All such funds shall be held by the Servicer in trust for the benefit
of the Certificateholders and the Certificate Insurer pursuant to the terms
hereof.

          (c) The Collection Account may, upon written notice by the Trustee to
the Certificate Insurer, be transferred to a different depository so long as
such transfer is to an Eligible Account.

          Section 5.04 PERMITTED WITHDRAWALS FROM THE COLLECTION ACCOUNT. The
Servicer may, from time to time, make withdrawals from the Collection Account
for the following purposes:

          (a) to reimburse itself for any accrued unpaid Servicing Fees and for
unreimbursed Periodic Advances and Servicing Advances. The Servicer's right to
reimbursement for unpaid Servicing Fees and unreimbursed Servicing Advances
shall be limited to late collections on the related Mortgage Loan, including
Liquidation Proceeds, Released Mortgaged Property Proceeds, Insurance Proceeds
and such other amounts as may be collected by the Master Servicer from the
related Mortgagor or otherwise relating to the Mortgage Loan in respect of which
such unreimbursed amounts are owed.  The Servicer's right to reimbursement for
unreimbursed Periodic Advances shall be limited to late collections of interest
on any Mortgage Loan and to Liquidation Proceeds and Insurance Proceeds on
related Mortgage Loans;

                                       46

 
          (b) to reimburse itself for any Periodic Advances or Servicing
Advances determined in good faith to have become Nonrecoverable Advances, such
reimbursement to be made from any funds in the Collection Account;

          (c) to withdraw any amount received from a Mortgagor that is
recoverable and sought to be recovered as a voidable preference by a trustee in
bankruptcy pursuant to the United States Bankruptcy Code in accordance with a
final, nonappealable order of a court having competent jurisdiction;

          (d) to withdraw any funds deposited in the Collection Account that
were not required to be deposited therein;

          (e) to pay itself Servicing Compensation pursuant to Section 5.14
hereof to the extent not retained or paid pursuant to Section 5.03, 5.04 or
5.14;

          (f) to pay to the Seller with respect to each Mortgage Loan or
property acquired in respect thereof that has been repurchased or replaced
pursuant to Section 2.04 or 3.03 or to pay to itself with respect to each
Mortgage Loan or property acquired in respect thereof that has been purchased
pursuant to Section 8.01 all amounts received thereon and not required to be
distributed as of the date on which the related repurchase or purchase price or
Principal Balance, as the case may be, was determined;

          (g) to pay to the Seller with respect to each Mortgage Loan the amount
of interest accrued and unpaid on such Mortgage Loan on the Cut-off Date (with
respect to the Initial Mortgage Loans) or Subsequent Cut-off Date (with respect
to the Subsequent Mortgage Loans);

          (h) to make deposits to the Certificate Accounts (which shall include
the Trustee Fee) in the amounts and in the manner provided for herein;

          (i) to pay itself any interest earned on or investment income earned
with respect to funds in the Collection Account;

          (j) to reimburse itself or the Depositor pursuant to Section 11.01;
and

          (k) to clear and terminate the Collection Account upon the termination
of this Agreement.

          The Servicer shall keep and maintain a separate accounting for each
Mortgage Loan for the purpose of accounting for withdrawals from the Collection
Account pursuant to subclause (a).

          Section 5.05 PAYMENT OF TAXES, INSURANCE AND OTHER CHARGES. With
respect to each Mortgage Loan, the Servicer shall maintain accurate records
reflecting casualty insurance coverage.

          With respect to each Mortgage Loan as to which the Servicer maintains
escrow accounts, the Servicer shall maintain accurate records reflecting the
status of ground rents, taxes, assessments, water rates and other charges which
are or may become a lien upon the 

                                       47

 
Mortgaged Property and the status of primary mortgage guaranty insurance
premiums, if any, and casualty insurance coverage and shall obtain, from time to
time, all bills for the payment of such charges (including renewal premiums) and
shall effect payment thereof prior to the applicable penalty or termination date
and at a time appropriate for securing maximum discounts allowable, employing
for such purpose deposits of the Mortgagor in any escrow account which shall
have been estimated and accumulated by the Servicer in amounts sufficient for
such purposes, as allowed under the terms of the Mortgage. To the extent that a
Mortgage does not provide for escrow payments, the Servicer shall, if it has
received notice of a default or deficiency, monitor such payments to determine
if they are made by the Mortgagor.

          Section 5.06 MAINTENANCE OF CASUALTY INSURANCE. The Servicer shall
cause to be maintained for each Mortgage Loan (at the expense of the borrower
or, if required by the terms of the Mortgage Loan and not paid for by the
borrower, at the expense of the Trust Fund) a casualty insurance policy with
extended coverage issued by a generally acceptable insurer in an amount which is
not less than the full insurable value of the Mortgaged Property securing such
Mortgage Loan or the unpaid principal balance of such Mortgage Loan, whichever
is less; provided, however, that such insurance may not be less than the minimum
amount required to fully compensate for any loss or damage on a replacement cost
basis. If, upon origination of the Mortgage Loan, the improvements on the
Mortgaged Property were in an area identified in the Federal Register by the
Federal Emergency Management Agency as having special flood hazards (and such
flood insurance has been made available) the Servicer will cause to be
maintained (at the expense of the borrower or, if required by the terms of the
Mortgage Loan and not paid for by the borrower, at the expense of the Trust
Fund) a flood insurance policy meeting the requirements of the current
guidelines of the Federal Insurance Administration with a generally acceptable
insurance carrier, in an amount representing coverage not less than the least of
(i) the unpaid principal balance of the Mortgage Loan, (ii) the full insurable
value and (iii) the maximum amount of insurance which was available under the
Flood Disaster Protection Act of 1973. The Servicer shall also maintain similar
fire insurance coverage and, if applicable, flood insurance on property acquired
upon foreclosure, or by deed in lieu of foreclosure, of any Mortgage Loan in an
amount which is at least equal to the lesser of (i) the full insurable value of
the improvements which are a part of such property and (ii) the principal
balance owing on such Mortgage Loan at the time of such foreclosure or grant of
deed in lieu of foreclosure; provided, however, that such insurance may not be
less than the minimum amount required to fully compensate for any loss or damage
on a replacement cost basis. It is understood and agreed that such insurance
shall be with insurers approved by the Servicer and that no earthquake or other
additional insurance is to be required of any Mortgagor, other than pursuant to
such applicable laws and regulations as shall at any time be in force and as
shall require such additional insurance. Pursuant to Section 5.03, any amounts
collected by the Servicer under any insurance policies maintained pursuant to
this Section 5.06 (other than amounts to be applied to the restoration or repair
of the related Mortgaged Property or released to the Mortgagor in accordance
with Accepted Servicing Practices) shall be deposited into the Collection
Account, subject to withdrawal pursuant to Section 5.04 unless such insurance
was not required by the terms of the Mortgage Loan. Any cost incurred by the
Servicer in maintaining any such insurance shall be added to the amount owing
under the Mortgage Loan where the terms of the Mortgage Loan so permit;
provided, however, that the addition of any such cost shall not be taken into
account for purposes of calculating the principal amount of the Mortgage Note or
Mortgage Loan, the Monthly Payments on the 

                                       48

 
Mortgage Note or the distributions to be made to the Certificateholders. Such
costs shall be recoverable by the Servicer pursuant to Section 5.04. In the
event that the Servicer shall obtain and maintain a blanket policy issued by an
insurer that is acceptable to FNMA or FHLMC, insuring against hazard losses on
all of the Mortgage Loans, it shall conclusively be deemed to have satisfied its
obligation as set forth in the first sentence of this Section 5.06, it being
understood and agreed that such policy may contain a deductible clause, in which
case the Servicer shall, in the event that there shall not have been maintained
on the related mortgaged or acquired property an insurance policy complying with
the first sentence of this Section 5.06 and there shall have been a loss which
would have been covered by such a policy had it been maintained, be required to
deposit from its own funds into the Collection Account the amount not otherwise
payable under the blanket policy because of such deductible clause.

          Section 5.07 MAINTENANCE OF MORTGAGE IMPAIRMENT INSURANCE POLICY. In
the event that the Servicer shall obtain and maintain a blanket policy (the
"Mortgage Impairment Insurance Policy") with an insurer either (i) having a
General Policy rating of A:VIII or better in Best's Key Rating Guide or (ii)
approved in writing by the Certificate Insurer, such approval not to be
unreasonably withheld, insuring against fire and hazards of extended coverage on
all of the Mortgage Loans, then, to the extent such policy names the Servicer as
loss payee and provides coverage in an amount equal to the aggregate unpaid
principal balance on the Mortgage Loans without co-insurance, and otherwise
complies with the requirements of Section 5.06, the Servicer shall be deemed
conclusively to have satisfied its obligations with respect to fire and hazard
insurance coverage under Section 5.06, it being understood and agreed that such
blanket policy may contain a deductible clause, in which case the Servicer
shall, in the event that there shall not have been maintained on the related
Mortgaged Property a policy complying with Section 5.06, and there shall have
been a loss which would have been covered by such policy, deposit in the
Collection Account the difference, if any, between the amount that would have
been payable under a policy complying with Section 5.06 and the amount paid
under such blanket policy. Upon the request of the Certificate Insurer, the
Trustee or any Certificateholder, the Servicer shall cause to be delivered to
the Certificate Insurer, the Trustee or such Certificateholder, as the case may
be, a certified true copy of such policy. The Servicer agrees to prepare and
present, on behalf of itself, the Trustee, the Certificate Insurer and
Certificateholders, claims under any such policy in a timely fashion in
accordance with the terms of such policy.

          Section 5.08 FIDELITY BOND; ERRORS AND OMISSIONS POLICY. (a) The
Servicer shall maintain with a responsible company, and at its own expense, a
blanket fidelity bond (a "Fidelity Bond") and an errors and omissions insurance
policy (an "Errors and Omissions Policy"), in a minimum amount acceptable to
FNMA or FHLMC or, if _______is the Servicer or if the Trustee is the successor
Servicer, in an amount generally maintained by prudent mortgage loan servicers
having servicing portfolios of a similar size.

          (b) The Servicer shall be deemed to have complied with this provision
if one of its respective Affiliates has such a Fidelity Bond and Errors and
Omissions Policy and, by the terms of such fidelity bond and errors and omission
policy, the coverage afforded thereunder extends to the Servicer.  Any such
Fidelity Bond and Errors and Omissions Policy shall not be cancelled or modified
in a materially adverse manner without 10 days prior written notice to the
Certificate Insurer.

                                       49

 
          Section 5.09 COLLECTION OF TAXES, ASSESSMENTS AND OTHER ITEMS;
SERVICING ACCOUNT. In addition to the Collection Account, the Servicer shall
establish and maintain a Servicing Account, which shall be an Eligible Account,
and shall deposit therein all payments by Mortgagors for taxes, assessments,
primary mortgage or hazard insurance premiums or comparable items. Withdrawals
from the Servicing Account may be made to effect payment of taxes, assessments,
primary mortgage or hazard insurance premiums or comparable items, to reimburse
the Servicer out of related collections for any advances made in the nature of
any of the foregoing, to refund to any Mortgagors any sums determined to be
overages, or to pay any interest owed to Mortgagors on such account to the
extent required by law or to clear and terminate the Servicing Account at the
termination of this Agreement upon the termination of the Trust Fund. The
Servicer shall advance the payments referred to in the first sentence of this
Section 5.09 that are not timely paid by the Mortgagors on the date when the
tax, premium or other cost for which such payment is intended is due, but the
Servicer shall be required to so advance only to the extent that such advances,
in the good faith judgment of the Servicer, will be recoverable by the Servicer
pursuant to Section 5.04 out of Liquidation Proceeds, Insurance Proceeds or
otherwise.

          Section 5.10 PERIODIC FILINGS WITH THE SECURITIES AND EXCHANGE
COMMISSION; ADDITIONAL INFORMATION. The Trustee shall prepare or cause to be
prepared for filing with the Commission any and all reports, statements and
information respecting the Trust Fund and/or the Certificates required to be
filed, and shall solicit any and all proxies of the Certificateholders whenever
such proxies are required to be solicited, pursuant to the Securities Exchange
Act of 1934, as amended. The Depositor shall promptly file, and exercise its
reasonable best efforts to obtain a favorable response to, no-action requests
with, or other appropriate exemptive relief from, the Commission seeking the
usual and customary exemption from such reporting requirements granted to
issuers of securities similar to the Certificates. Fees and expenses incurred by
the Trustee in connection with the foregoing shall be reimbursed pursuant to
Section 9.05 and shall not be paid by the Trust Fund.

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

          Section 5.11 ENFORCEMENT OF DUE-ON-SALE CLAUSES; ASSUMPTION
AGREEMENTS. In any case in which a Mortgaged Property is about to be conveyed by
the Mortgagor (whether by absolute conveyance or by contract of sale, and
whether or not the Mortgagor remains liable thereon) and the Servicer has
knowledge of such prospective conveyance, the Servicer shall effect assumptions
in accordance with the terms of any due-on-sale provision contained in the
related Mortgage Note or Mortgage. The Servicer shall enforce any due-on-sale
provision contained in such Mortgage Note or Mortgage to the extent the
requirements thereunder for an assumption of the Mortgage Loan have not been
satisfied to the extent permitted under the terms of the related Mortgage Note,
unless such provision is not exercisable under applicable law and governmental
regulations or in the Servicer's judgment, such exercise is reasonably likely to
result in legal action by the Mortgagor, or such conveyance is in connection
with a permitted assumption of the related 

                                       50

 
Mortgage Loan. Subject to the foregoing, the Servicer is authorized to take or
enter into an assumption agreement from or with the Person to whom such property
is about to be conveyed, pursuant to which such person becomes liable under the
related Mortgage Note and, unless prohibited by applicable state law, the
Mortgagor remains liable thereon. The Servicer is also authorized, to release
the original Mortgagor from liability upon the Mortgage Loan and substitute the
new Mortgagor as obligor thereon. In connection with such assumption or
substitution, the Servicer shall apply such underwriting standards and follow
such practices and procedures as shall be normal and usual for mortgage loans
similar to the Mortgage Loans and as it applies to mortgage loans owned solely
by it. The Servicer shall notify the Trustee that any such assumption or
substitution agreement has been completed by forwarding to the Trustee the
original copy of such assumption or substitution agreement, which copy shall be
added by the Trustee to the related Mortgage File and shall, for all purposes,
be considered a part of such Mortgage File to the same extent as all other
documents and instruments constituting a part thereof. In connection with any
such assumption or substitution agreement, the Mortgage Interest Rate of the
related Mortgage Note, the payment terms and other material terms shall not be
changed. Any fee collected by the Servicer for entering into an assumption or
substitution of liability agreement will be retained by the Servicer as
servicing compensation.

          Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any conveyance by the
Mortgagor of the property subject to the Mortgage or any assumption of a
Mortgage Loan by operation of law which the Servicer in good faith determines 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 or, in the Servicer's judgment, be reasonably likely
to result in legal action by the Mortgagor.

          Section 5.12 REALIZATION UPON DEFAULTED MORTGAGE LOANS.

          (a) Except as provided in the last two paragraphs of this Section
5.12(a), the Servicer shall foreclose upon or otherwise comparably convert the
ownership of properties securing such of the Mortgage Loans as come into and
continue in default and as to which no satisfactory arrangements can be made for
collection of delinquent payments pursuant to Section 5.03. In connection with
such foreclosure or other conversion, the Servicer shall follow Accepted
Servicing Practices. The foregoing is subject to the proviso that the Servicer
shall not be required to expend its own funds in connection with any foreclosure
or to restore any damaged property unless it shall determine that (i) such
foreclosure and/or restoration will increase the proceeds of liquidation of the
Mortgage Loan to Certificateholders after reimbursement to itself for such
expenses and (ii) such expenses will be recoverable to it through Liquidation
Proceeds (respecting which it shall have priority for purposes of withdrawal
from the Collection Account pursuant to Section 5.04) or otherwise. The Servicer
shall be entitled to reimbursement of the Servicing Fee and other amounts due
it, if any, to the extent, but only to the extent, that withdrawals from the
Collection Account with respect thereto are permitted under Section 5.04.

          The Servicer may foreclose against the Mortgaged Property securing a
defaulted Mortgage Loan either by foreclosure, by sale or by strict foreclosure,
and in the event a 

                                       51

 
deficiency judgment is available against the Mortgagor or any other person, may
proceed for the deficiency.

          In the event that title to any Mortgaged Property is acquired in
foreclosure or by deed in lieu of foreclosure (an "REO Property"), the deed or
certificate of sale shall be issued to the Servicer on behalf of the Trustee in
the name of the Trustee on behalf of the Certificateholders. The Servicer shall
administer the REO Property so that it qualifies at all times as "foreclosure
property," within the meaning of Section 860G(a)(8) of the Code, and shall not
permit any income to be earned with respect thereto that is "net income from
foreclosure property" within the meaning of Section 860G(d) of the Code or
"income from non-permitted assets" within the meaning of Section 860F(a)(2)(B)
of the Code. Notwithstanding any such acquisition of title and cancellation of
the related Mortgage Loan, such Mortgage Loan shall be considered to be a
Mortgage Loan held in the Trust Fund until such time as the related Mortgaged
Property shall be sold and such Mortgage Loan becomes a Liquidated Mortgage
Loan. Consistent with the foregoing, for purposes of all calculations hereunder,
so long as such Mortgage Loan shall be considered to be an Outstanding Mortgage
Loan:
        (i) It shall be assumed that, notwithstanding that the indebtedness
     evidenced by the related Mortgage Note shall have been discharged, such
     Mortgage Note and the related amortization schedule in effect at the time
     of any such acquisition of title (after giving effect to any previous
     Curtailments and before any adjustment thereto by reason of any bankruptcy
     or similar proceeding or any moratorium or similar waiver or grace period)
     remain in effect, except that such schedule shall be adjusted to reflect
     the application of Net REO Proceeds received in any month pursuant to the
     succeeding clause.

        (ii) Net REO Proceeds received in any month shall be deemed to have been
     received first in payment of the accrued interest that remained unpaid on
     the date that such Mortgage Loan became an REO Mortgage Loan, with the
     excess thereof, if any, being deemed to have been received in respect of
     the delinquent principal installments that remained unpaid on such date.
     Thereafter, Net REO Proceeds received in any month shall be applied to the
     payment of installments of principal and accrued interest on such Mortgage
     Loan deemed to be due and payable in accordance with the terms of such
     Mortgage Note and such amortization schedule. If such Net REO Proceeds
     exceed the then Unpaid REO Amortization, the excess shall be treated as a
     Curtailment received in respect of such Mortgage Loan.

        (iii) Only that portion of Net REO Proceeds allocable to interest that
     bears the same relationship to the total amount of Net REO Proceeds
     allocable to interest as the rate of the Servicing Fee bears to the
     Mortgage Interest Rate borne by such Mortgage Loan shall be allocated to
     the Servicing Fee with respect thereto.

        In the event that the Trust Fund acquires any Mortgaged Property as
aforesaid or otherwise in connection with a default or reasonably foreseeable
default on a Mortgage Loan, such Mortgaged Property shall be disposed of by or
on behalf of the Trust Fund within three years after its acquisition by the
Trust Fund unless (a) the Servicer shall have provided to the Trustee an Opinion
of Counsel (at the expense of the Trust Fund) to the effect that the 

                                       52

 
holding by the Trust Fund of such Mortgaged Property subsequent to three years
after its acquisition (and specifying the period beyond such three-year period
for which the Mortgaged Property may be held) will not cause the Trust Fund to
be subject to the tax on prohibited transactions imposed by Section 860F(a)(1)
of the Code, otherwise subject the Trust Fund to tax or cause the Trust Fund to
fail to qualify as a REMIC at any time that any Certificates are outstanding, or
(b) the Servicer (at the Trust Fund's expense) shall have applied for, at least
60 days prior to the expiration of such three-year period, an extension of such
three-year period in the manner contemplated by Section 856(e)(3) of the Code,
in which case the three-year period shall be extended by the applicable period.
The Servicer shall further ensure that the Mortgaged Property is administered so
that it constitutes "foreclosure property" within the meaning of Section
860G(a)(8) of the Code at all times, that the sale of such property does not
result in the receipt by the Trust Fund of any income from non-permitted assets
as described in Section 860F(a)(2)(B) of the Code, and that the Trust Fund does
not derive any "net income from foreclosure property" within the meaning of
Section 860G(c)(2) of the Code with respect to such property.

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

          In lieu of foreclosing upon any defaulted Mortgage Loan, the Servicer
may, in its discretion, permit the assumption of such Mortgage Loan if, in the
Servicer's judgment, such default is unlikely to be cured and if the assuming
borrower satisfies the Servicer's underwriting guidelines with respect to
mortgage loans owned by the Servicer. In connection with any such assumption,
the Mortgage Interest Rate of the related Mortgage Note and the payment terms
shall not be changed. Any fee collected by the Servicer for entering into an
assumption agreement will be retained by the Servicer as servicing compensation.
Alternatively, the Servicer may encourage the refinancing of any defaulted
Mortgage Loan by the Mortgagor.

          Notwithstanding the foregoing, prior to instituting foreclosure
proceedings or accepting a deed-in-lieu of foreclosure with respect to any
Mortgaged Property, the Servicer shall make, or cause to be made, inspection of
the Mortgaged Property in accordance with the Accepted Servicing Practices and,
with respect to environmental hazards, such procedures are as required by the
provisions of the FNMA's selling and servicing guide applicable to single-family
homes and in effect on the date hereof. The Servicer shall be entitled to rely
upon the results of any such inspection made by others. In cases where the
inspection reveals that such Mortgaged Property is potentially contaminated with
or affected by hazardous wastes or hazardous substances, the Servicer shall
promptly give written notice of such fact to the Certificate Insurer, the
Trustee and each Class A Certificateholder. The Servicer shall not commence
foreclosure proceedings or accept a deed-in-lieu of foreclosure for Mortgaged
Property with respect to this paragraph without obtaining the written consent of
the Certificate Insurer.

          (b) Promptly after the Closing Date, the Servicer shall, with respect
to each Mortgage Loan for which the Mortgage provides a second lien on the
related Mortgaged Property, cause to be recorded in the appropriate public
office for real property records, where permitted by applicable law and where
applicable law does not require that a second mortgagee be named as a party
defendant in foreclosure or comparable proceedings in order to foreclose 

                                       53

 
or otherwise preempt such mortgagee's equity of redemption, a request for notice
of any action by or on behalf of any mortgagee under a Senior Mortgage Loan. The
Servicer also shall promptly provide written notice to each mortgagee under a
Senior Mortgage Loan of the existence of the related Mortgage Loan and request
notification of any action taken or to be taken against the related Mortgagor or
Mortgaged Property by or on behalf of such mortgagee in respect of such Senior
Mortgage Loan.

          (c) Upon becoming aware that a Senior Mortgage Loan has come into
default or of any action that the related mortgagee has taken or may take in
respect thereof, the Servicer shall, consistent with the REMIC Provisions, take
such actions as it shall deem necessary or advisable, as shall be normal and
usual in its general mortgage servicing activities and as shall be required or
permitted by Accepted Servicing Practices. The Servicer, however, shall not be
required to expend its own funds in connection therewith unless it shall
determine that such expense will be recoverable to it. All such expenses shall
be included as Liquidation Expenses pursuant to the definition thereof, and
shall be reimbursable from the related Liquidation Proceeds in accordance with
Section 5.04.

          Section 5.13 TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES. Upon the
payment in full of any Mortgage Loan, or the receipt by the Servicer of a
notification that payment in full will be escrowed in a manner customary for
such purposes, the Servicer shall immediately notify the Trustee in the form of
a Request for Release in the form attached hereto as Exhibit H (which request
shall include a statement to the effect that all amounts received in connection
with such payment which are required to be deposited in the Collection Account
pursuant to Section 5.03 have been or shall be so deposited) of a Servicing
Officer and shall request delivery to it of the Mortgage File. Upon receipt of
such Request for Release, the Trustee, or the Custodian on its behalf, shall
promptly release the related Mortgage File to the Servicer. Upon any such
payment in full, the Servicer is authorized to give, as agent for the Trustee
and the mortgagee under the Mortgage which secured the Mortgage Loan, an
instrument of satisfaction (or assignment of mortgage without recourse)
regarding the property subject to such Mortgage, which instrument of
satisfaction or assignment, as the case may be, shall be delivered to the Person
or Persons entitled thereto against receipt therefor of such payment, it being
understood and agreed that no expenses incurred in connection with such
instrument of satisfaction or assignment, as the case may be, shall be
chargeable to the Collection Account. In connection therewith, the Trustee shall
execute and return to the Servicer any required power of attorney provided to
the Trustee by the Servicer and other required documentation in accordance with
Section 5.01(c). From time to time and as appropriate for the servicing or
foreclosure of any Mortgage Loan and in accordance with Accepted Servicing
Practices, the Trustee shall, upon request of the Servicer and delivery to the
Trustee of a Request for Release signed by a Servicing Officer, release, or
cause the Custodian to release, the related Mortgage File to the Servicer and
shall execute such documents as shall be necessary to the prosecution of any
such proceedings. Such Request for Release shall obligate the Servicer to return
the Mortgage File to the Trustee when the need therefor by the Servicer no
longer exists unless the Mortgage Loan shall be liquidated, in which case, upon
receipt of a certificate of a Servicing Officer similar to the Request for
Release hereinabove specified, the Mortgage File shall be delivered by the to
the Servicer.

          Section 5.14 SERVICING FEE; SERVICING COMPENSATION. The Servicer shall
be entitled, at its election, either (a) to pay itself the Servicing Fee out of
any Mortgagor 

                                       54

 
payment on account of interest or Net REO Proceeds prior to the deposit of such
payment in the Collection Account or (b) to withdraw from the Collection Account
such Servicing Fee pursuant to Section 5.04. The Servicer shall also be
entitled, at its election, either (a) to pay itself the Servicing Fee in respect
of each delinquent Mortgage Loan out of Liquidation Proceeds in respect of such
Mortgage Loan or other recoveries with respect thereto to the extent permitted
in Section 5.03(a) to withdraw from the Collection Account the Servicing Fee in
respect of each such Mortgage Loan to the extent of such Liquidation Proceeds or
other recoveries, to the extent permitted by Section 5.04(a).

          Servicing compensation in the form of Net Foreclosure Profits,
prepayment penalties, assumption fees, late payment charges, tax service fees,
fees for statement of account or payoff of the Mortgage Loan (to the extent
permitted by applicable law) or otherwise shall be retained by the Servicer and
are not required to be deposited in the Collection Account. The aggregate
Servicing Fee is reserved for the administration of the Trust Fund and, in the
event of replacement of the Master Servicer as servicer of the Mortgage Loans,
for the payment of other expenses related to such replacement. The aggregate
Servicing Fee shall be offset as provided in Section 5.20. The Servicer shall be
required to pay all expenses incurred by it in connection with its servicing
activities hereunder (including maintenance of the hazard insurance required by
Section 5.05) and shall not be entitled to reimbursement therefor except as
specifically provided herein.

          Section 5.15 REPORTS TO THE TRUSTEE AND THE DEPOSITOR; COLLECTION
ACCOUNT STATEMENTS. Not later than 15 days after each Distribution Date, the
Servicer shall provide to the Trustee and the Depositor a statement, certified
by a Servicing Officer, setting forth the status of the Collection Account as of
the close of business on the last day of the immediately preceding calendar
month, stating that all distributions required by this Agreement to be made by
the Servicer on behalf of the Trustee have been made (or if any required
distribution has not been made by the Servicer, specifying the nature and status
thereof) and showing, for the period covered by such statement, the aggregate of
deposits into and withdrawals from the Collection Account for each category of
deposit specified in Section 5.03 and each category of withdrawal specified in
Section 5.04 and the aggregate of deposits into the Certificate Accounts as
specified in Section 6.01(c). Such statement shall also state the aggregate
unpaid principal balance of all the Mortgage Loans as of the close of business
on the last day of the month preceding the month in which such Distribution Date
occurs. Copies of such statement shall be provided by the Trustee to any
Certificateholder upon request.

          Section 5.16 ANNUAL STATEMENT AS TO COMPLIANCE. The Servicer will
deliver to the Trustee, the Certificate Insurer and the Rating Agencies on or
before ________ each year, beginning with _____, 199_, an Officers' Certificate
stating as to each signer thereof, that (i) a review of the activities of the
Servicer during the preceding calendar year and of its performance under this
Agreement has been made under such officer's supervision, and (ii) to the best
of such officer's knowledge, based on such review, the Servicer has fulfilled
all its obligations under this Agreement throughout such year, or if there has
been a default in the fulfillment of any such obligation, specifying each such
default known to such officer and the nature and status thereof. Such Officers'
Certificate shall be accompanied by the statement described in Section 5.17 of
this Agreement. Copies of such 

                                       55

 
statement shall, upon request, be provided to any Certificateholder by the
Servicer, or by the Trustee at the Servicer's expense if the Servicer shall fail
to provide such copies.

          Section 5.17 ANNUAL INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING REPORT.
On or before _________ of every year, beginning with _______, 199_, the
Servicer, at its expense, shall cause a firm of nationally recognized
independent public accountants to furnish a statement to the Trustee, the
Certificate Insurer and the Rating Agencies to the effect that, on the basis of
an examination of certain documents and records relating to the servicing of the
mortgage loans being serviced by the Servicer under pooling and servicing
agreements similar to this Agreement, conducted substantially in compliance with
the Uniform Single Attestation Program for Mortgage Bankers, such firm is of the
opinion that such servicing has been conducted in compliance with this
Agreement. Copies of such statement shall, upon request, be provided to
Certificateholders by the Servicer, or by the Trustee at the Servicer's expense
if the Servicer shall fail to provide such copies. For purposes of such
statement, such firm may conclusively presume that any pooling and servicing
agreement which governs mortgage pass-through certificates offered by the
Depositor (or any predecessor or successor thereto) in a registration statement
under the Securities Act of 1933, as amended, is similar to this Agreement,
unless such other pooling and servicing agreement expressly states otherwise.

          Section 5.18 OPTIONAL PURCHASE OF DEFAULTED MORTGAGE LOANS. Any
Affiliate of the Seller, in its sole discretion, shall have the right to elect
(by written notice sent to the Servicer, the Trustee and the Certificate
Insurer), but shall not be obligated, to purchase for its own account from the
Trust Fund any Mortgage Loan which is 90 days or more Delinquent in the manner
and at the price specified in Section 2.04(b). The purchase price for any
Mortgage Loan purchased hereunder shall be deposited in the Collection Account
and the Trustee, upon receipt of such deposit, shall release or cause to be
released to the purchaser of such Mortgage Loan the related Mortgage File and
shall execute and deliver such instruments of transfer or assignment prepared by
the purchaser of such Mortgage Loan, in each case without recourse, as shall be
necessary to vest in the purchaser of such Mortgage Loan any Mortgage Loan
released pursuant hereto and the purchaser of such Mortgage Loan shall succeed
to all the Trustee's right, title and interest in and to such Mortgage Loan and
all security and documents related thereto. Such assignment shall be an
assignment outright and not for security. The purchaser of such Mortgage Loan
shall thereupon own such Mortgage Loan, and all security and documents, free of
any further obligation to the Trustee or the Certificateholders with respect
thereto.

          Section 5.19 REPORTS TO BE PROVIDED BY THE SERVICER. The Servicer
agrees to make available on a reasonable basis to the Certificate Insurer a
knowledgeable financial or accounting officer for the purpose of answering
reasonable questions respecting recent developments affecting the Servicer or
the financial statements of the Servicer and to permit the Certificate Insurer
to inspect the Servicer's servicing facilities during normal business hours for
the purpose of satisfying the Certificate Insurer that the Servicer has the
ability to service the Mortgage Loans in accordance with this Agreement.

          Section 5.20 ADJUSTMENT OF SERVICING COMPENSATION IN RESPECT OF
PREPAID MORTGAGE LOANS. The aggregate amount of the Servicing Fees that the
Servicer shall be entitled to receive with respect to all of the Mortgage Loans
and each 

                                       56

 
Distribution Date shall be offset on such Distribution Date by an amount equal
to the aggregate Prepayment Interest Shortfall with respect to all Mortgage
Loans which were subjects of Principal Prepayments in Full or Curtailments
during the month preceding the month of such Distribution Date. The amount of
any offset against the aggregate Servicing Fee with respect to any Distribution
Date under this Section 5.20 shall be limited to the aggregate amount of the
Servicing Fees otherwise payable to the Servicer (without adjustment on account
of Prepayment Interest Shortfalls) with respect to (i) scheduled payments having
the Due Date occurring in the month of such Distribution Date received by the
Servicer prior to the Servicer Remittance Date, and (ii) Principal Prepayments
in Full, Curtailments and Liquidation Proceeds received in the month preceding
the month in which such Distribution Date occurs, and the rights of the
Certificateholders to the offset of the aggregate Prepayment Interest Shortfalls
shall not be cumulative.

          Section 5.21 PERIODIC ADVANCES. If, on any Servicer Remittance Date,
the Servicer determines that any Monthly Payments due on the Due Date
immediately preceding such Servicer Remittance Date have not been received as of
the close of business on the Business Day preceding such Servicer Remittance
Date, the Servicer shall determine the amount of any Periodic Advance required
to be made with respect to the related Distribution Date. The Servicer shall, on
the Servicer Remittance Date, deliver in a computer-readable form (including
electronic transmission) to the Trustee indicating the payment status of each
Mortgage Loan as of the Business Day prior to such Servicer Remittance Date. The
Servicer shall include in the amount to be deposited in the related Certificate
Account on such Servicer Remittance Date an amount equal to the Periodic
Advance, if any, which deposit may be made in whole or in part from funds in the
Collection Account being held for future distribution or withdrawal on or in
connection with Distribution Dates in subsequent months. Any funds being held
for future distribution to Certificateholders and so used shall be replaced by
the Servicer from its own funds by deposit in the related Certificate Account on
or before the Business Day preceding any such future Servicer Remittance Date to
the extent that funds in the related Certificate Account on such Servicer
Remittance Date shall be less than payments to Certificateholders required to be
made on such date.

          The Servicer shall designate on its records the specific Mortgage
Loans and related installments (or portions thereof) as to which such Periodic
Advance shall be deemed to have been made, such determination being conclusive
for purposes of withdrawals from the Collection Account pursuant to Section
5.04.

          Section 5.22 THIRD PARTY CLAIMS. The Trustee shall reimburse the
Seller from amounts otherwise distributable on the Class R Certificates for all
amounts advanced by the Seller pursuant to the second sentence of Section
4.03(a)(ii) of the Purchase Agreement except when the relevant claim relates
directly to the failure of the Seller to perform its duties in compliance with
the terms of the Purchase Agreement.

          Section 5.23 MAINTENANCE OF CORPORATE EXISTENCE AND LICENSES; MERGER
OR CONSOLIDATION OF THE SERVICER. (a) The Servicer will keep in full effect its
existence, rights and franchises as a corporation, will obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction
necessary to protect the validity and enforceability of this Agreement or any of
the Mortgage Loans and to perform its duties under this Agreement and will
otherwise operate its business so as to cause the 

                                       57

 
representations and warranties under Section 3.01 to be true and correct at all
times under this Agreement.

          (b) Any Person into which the Servicer may be merged or consolidated,
or any corporation resulting from any merger, conversion or consolidation to
which the Master Servicer shall be a party, or any Person succeeding to the
business of the Servicer, shall be an established mortgage loan servicing
institution acceptable to the Certificate Insurer that has a net worth of at
least $15,000,000, and in all events shall be the successor of the Servicer
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
Servicer shall send notice of any such merger or consolidation to the Trustee
and the Certificate Insurer.

          Section 5.24 ASSIGNMENT OF AGREEMENT BY SERVICER; SERVICER NOT TO
RESIGN. The Servicer shall not assign this Agreement or resign from the
obligations and duties hereby imposed on it except by mutual consent of the
Certificate Insurer and the Trustee or upon the determination that the
Servicer's duties hereunder are no longer permissible under applicable law and
that such incapacity cannot be cured by the Servicer without incurring, in the
reasonable judgment of the Certificate Insurer, unreasonable expense. Any such
determination that the Servicer's duties hereunder are no longer permissible
under applicable law permitting the resignation of the Servicer shall be
evidenced by a written Opinion of Counsel (who may be counsel for the Servicer)
to such effect delivered to the Trustee, the Seller, the Depositor and the
Certificate Insurer. No such resignation shall become effective until the
Trustee or a successor appointed in accordance with the terms of this Agreement
has assumed the Servicer's responsibilities and obligations hereunder in
accordance with Section 7.02. The Servicer shall provide the Trustee, the Rating
Agencies and the Certificate Insurer with 30 days prior written notice of its
intention to resign pursuant to this Section 5.24.

          Section 5.25 INFORMATION REPORTS TO BE FILED BY THE SERVICER. The
Servicer shall file information returns with respect to the receipt of mortgage
interest received in a trade or business, reports of foreclosures and
abandonments of any Mortgaged Property and cancellation of indebtedness income
with respect to any Mortgaged Property as required by Sections 6050H, 6050J and
6050P of the Code, respectively.

                           DISTRIBUTIONS AND PAYMENTS

          Section 6.01 ESTABLISHMENT OF CERTIFICATE ACCOUNTS; DEPOSITS TO THE
CERTIFICATE ACCOUNTS. (a) The Trustee shall establish and maintain a Certificate
Account which shall be titled "Certificate Account, _____________________, as
trustee for the registered holders of ACE Securities Corp., Asset-Backed
Certificates, Series 199_-_, Class A-1, Class A-2, Class A-3, Class A-4, and
Class R" which shall be an Eligible Account.

          (b) The Servicer may direct the Trustee in writing to invest the funds
in the Certificate Account only in Permitted Investments. No Permitted
Investment shall be sold or disposed of at a gain prior to maturity unless the
Servicer has delivered to the Trustee an Opinion of Counsel (at the Servicer's
expense) that such sale or disposition will not cause the Trust Fund to be
subject to the tax on income from prohibited transactions imposed by Section
860F(a)(1) of the Code, otherwise subject the Trust Fund to tax or cause the
Trust Fund to fail to qualify as a REMIC. All income (other than any gain from a
sale or disposition of the type referred to in the preceding sentence) realized
from any such Permitted Investment shall be for the benefit of the Servicer as
additional servicing compensation. The amount of any losses incurred in respect
of any such investments shall be deposited in the related Certificate Account by
the Servicer out of its own funds immediately as realized.

          (c) On each Servicer Remittance Date, the Servicer shall cause to be
deposited in the Certificate Account, from funds on deposit in the Collection
Account, an amount equal to the Servicer Remittance Amount.

          Section 6.02 PERMITTED WITHDRAWALS FROM THE CERTIFICATE ACCOUNT. The
Trustee shall withdraw or cause to be withdrawn funds from the Certificate
Account for the following purposes:

          (a)  to effect the distributions described in Section 6.05;

          (b) to pay to the Seller with respect to each Mortgage Loan or
property acquired in respect thereof that has been repurchased or replaced
pursuant to Section 2.04 or 3.03 or to pay to the Servicer with respect to each
Mortgage Loan or property acquired in respect thereof that has been purchased
all amounts received thereon and not required to be distributed as of the date
on which the related repurchase or purchase price or Principal Balance was
determined;

          (c) to pay the Servicer any interest earned on or investment income
earned with respect to funds in the Certificate Accounts;

          (d) to return to the Collection Account any amount deposited in the
Certificate Account that was not required to be deposited therein;

          (e) to make reimbursements to itself in accordance with Section 9.05;
and

                                       59

 
          (f) to clear and terminate the Certificate Accounts upon termination
of any of the Trust Fund pursuant to Article VIII.

          The Trustee shall keep and maintain a separate accounting for
withdrawals from the Certificate Account pursuant to each of subclauses (a)
through (f) listed above.

          Section 6.03 COLLECTION OF MONEY. Except as otherwise expressly
provided herein, the Trustee may demand payment or delivery of all money and
other property payable to or receivable by the Trustee pursuant to this
Agreement, including (a) all payments due on the Mortgage Loans in accordance

Trustee shall hold all such money and property received by it, as part of the
Trust Fund and shall apply it as provided in this Agreement.

          Section 6.04 THE CERTIFICATE INSURANCE POLICY. (a) Within two Business
Days after each Servicer Remittance Date the Trustee shall determine with
respect to the immediately following Distribution Date the amount to be on
deposit in the Certificate Account on such Distribution Date as a result of the
Servicer's remittance of the Servicer Remittance Amount on the related Servicer
Remittance Date plus the amount of any amounts deposited into the Certificate
Account from the Pre-Funding Account pursuant to Section 6.12 and any
Capitalized Interest Amount to be deposited pursuant to Section 6.13 for such
Distribution Date less the amounts described in clauses (i) through (ii) of
Section 6.05(b) or (c) for the related Distribution Date, and not including the
amount of any Insured Payment which is required to be deposited in the
Certificate Account for such Distribution Date. The amounts described in the
preceding sentence, with respect to each Distribution Date are the "Available
Funds" for such Distribution Date.

          (b) If on any Distribution Date there is an Available Funds Shortfall,
the Trustee shall complete a Notice in the form of Exhibit A to the related
Certificate Insurance Policy and submit such notice to the Certificate Insurer
no later than 12:00 noon New York City time on the second Policy Business Day
preceding such Distribution Date as a claim for an Insured Payment in an amount
equal to such Available Funds Shortfall.

          (c) The Trustee shall establish a separate Eligible Account for the
benefit of Holders of the Certificates and the Certificate Insurer referred to
herein as the "Certificate Insurance Payments Account" over which the Trustee
shall have exclusive control and sole right of withdrawal. The Trustee shall
deposit upon receipt any amount paid under the Certificate Insurance Policy in
the Certificate Insurance Payments Account and distribute such amount only for
purposes of payment to Certificateholders of the Insured Distribution Amount for
which a claim was made and such amount may not be applied to satisfy any costs,
expenses or liabilities of the Servicer, the Trustee or the Trust Fund. Amounts
paid under the Certificate Insurance Policy, to the extent needed to pay the
Insured Distribution Amount shall be transferred by the Trustee from the
Certificate Insurance Payments Account to the Certificate Account on the related
Distribution Date and disbursed by the Trustee to Certificateholders in
accordance with Section 6.05. It shall not be necessary for payments made under
the Certificate Insurance Policy to be made by checks or wire transfers separate
from other amounts distributed pursuant to Section 6.05. However, the amount of
any payment of principal or of interest on the Certificates to be paid from
funds transferred from the 

                                       60

 
Certificate Insurance Payments Account shall be noted as provided in paragraph
(d) below. Funds held in the Certificate Insurance Payments Account shall not be
invested. Any funds remaining in the Certificate Insurance Payments Account on
the first Policy Business Day following a Distribution Date shall be returned to
the Certificate Insurer pursuant to the written instructions of the Certificate
Insurer by the end of such Policy Business Day.

          (d) The Trustee Remittance Report shall indicate the amount of
interest and principal paid in respect of the Class A Certificates from moneys
received under the Certificate Insurance Policy.

          (e) In the event that the Trustee has received a certified copy of an
order of the appropriate court that any Insured Payment has been voided in whole
or in part as a preference payment under applicable bankruptcy law, the Trustee
shall so notify the Certificate Insurer, shall comply with the provisions of the
Certificate Insurance Policy to obtain payment by the Certificate Insurer of
such voided Insured Payment, and shall, at the time it provides notice to the
Certificate Insurer, notify, by mail to Certificateholders of the affected
Certificates that, in the event any Certificateholder's Insured Payment is so
recovered, such Certificateholder will be entitled to payment pursuant to the
Certificate Insurance Policy, a copy of which shall be made available through
the Trustee, the Certificate Insurer or the Certificate Insurer's fiscal agent,
if any, and the Trustee shall furnish to the Certificate Insurer or its fiscal
agent, if any, its records evidencing the payments which have been made by the
Trustee and subsequently recovered from Certificateholders, and dates on which
such payments were made.

          (f) The Trustee shall promptly notify the Certificate Insurer of any
proceeding or the institution of any action, of which a Responsible Officer of
the Trustee has actual knowledge, seeking the avoidance as a preferential
transfer under applicable bankruptcy, insolvency, receivership or similar law (a
"Preference Claim") of any distribution made with respect to the Certificates.
Each Certificateholder, by its purchase of Certificates, the Servicer and the
Trustee agree that, the Certificate Insurer (so long as no Certificate Insurer
Default exists) may at any time during the continuation of any proceeding
relating to a Preference Claim direct all matters relating to such Preference
Claim, including, without limitation, (i) the direction of any appeal of any
order relating to such Preference Claim and (ii) the posting of any surety,
supersedeas or performance bond pending any such appeal. In addition and without
limitation of the foregoing, the Certificate Insurer shall be subrogated to, and
each Certificateholder, the Servicer and the Trustee hereby delegate and assign
to the Certificate Insurer, to the fullest extent permitted by law, the rights
of the Servicer, the Trustee and each Certificateholder in the conduct of any
such Preference Claim, including, without limitation, all rights of any party to
any adversary proceeding or action with respect to any court order issued in
connection with any such Preference Claim.

          Section 6.05 DISTRIBUTIONS. (a) No later than 12:00 noon New York time
on each Servicer Remittance Date, the Servicer shall deliver to the Trustee a
report in computer-readable form (including electronic transmission, provided
that a portion of such report relating to certain delinquency information may be
delivered in hard copy form rather than computer-readable form) containing such
information as to each Mortgage Loan as of such date and such other information
as the Trustee shall reasonably require.

after all preceding allocations, transfers and disbursements have occurred:

          (i) to the Certificate Insurer, the Premium Amount;

          (ii) to the Trustee, an amount equal to the Trustee's Fees;

          (iii) to the Certificate Insurer the lesser of (x) an amount equal to
     (i) the amount then on deposit in the Certificate Account remaining after

     any, as of such Distribution Date;

          (iv) from amounts then on deposit in the Certificate Account
     (including any Insured Payments), to the Class A Certificateholders an
     amount equal to the Class A Interest Distribution Amount;

          (v) from amounts then on deposit in the Certificate Account (including
     any Insured Payments), to the Class A Certificateholders an amount equal to
     the lesser of (a) the Class A Principal Distribution Amount and (b) the
     amount remaining in the Certificate Account after distributions pursuant to
     clauses (i) through (iv) above; and;

     Holders of the Class R Certificates, the amount remaining on such
     Distribution Date, if any.

          Notwithstanding clause (v) above, the aggregate amounts distributed on
all Distribution Dates to the Holders of the Class A Certificates on account of
the Class A Principal Distribution Amount shall not exceed the aggregate
Original Security Balance for the Class A Certificates.

          Distributions of the Class A Principal Distribution Amount shall be

Certificate Insurance Payments Account) held by the Trustee shall be invested
and reinvested by the Trustee, as directed in writing by the Servicer (with
respect to the Certificate Accounts) or the Depositor (with respect to the Pre-

                                       62

 
          (b) Subject to Section 9.01 hereof, the Trustee shall not in any way
be held liable by reason of any insufficiency in any Account held by the Trustee
resulting from any investment loss on any Permitted Investment included therein
(except to the extent that the Trustee is the obligor and has defaulted thereon
or as provided in subsection (b) of this Section 6.06).

          (c) So long as no Event of Default shall have occurred and be
continuing, all net income and gain realized from investment of, and all
earnings on, funds deposited in any Account (excluding the Pre-Funding Account
and the Capitalized Interest Account) shall be for the benefit of the Servicer
as servicing compensation (in addition to the Servicing Fee). The Servicer shall
deposit in each Account (excluding the Pre-Funding Account and the Capitalized
Interest Account) and the Depositor shall deposit in each Pre-Funding Account
and Capitalized Interest Account, the amount of any loss incurred in respect of
any Permitted Investment held therein which is in excess of the income and gain

shall not be considered payment of the Certificates from the Trust Fund. The
Depositor, the Servicer and the Trustee acknowledge, and each Holder by its
acceptance of a Certificate agrees, that without the need for any further action
on the part of the Certificate Insurer, the Depositor, the Servicer, the Trustee
or the Certificate Registrar (a) to the extent the Certificate Insurer makes
payments, directly or indirectly, on account of principal of or interest on the
Class A Certificates to the Holders of such Certificates, the Certificate
Insurer will be fully subrogated to, and each Certificateholder, the Servicer
and the Trustee hereby delegate and assign to the Certificate Insurer, to the
fullest extent permitted by law, the rights of such Holders to receive such
principal and interest from the Trust Fund, including, without limitation, any
amounts due to the Certificateholders in respect of securities law violations
arising from the offer and sale of the Class A Certificates, and (b) the
Certificate Insurer shall be paid such amounts but only from the sources and in
the manner provided herein for the payment of such amounts. The Trustee and the
Servicer shall cooperate in all respects with any reasonable request by the
Certificate Insurer for action to preserve or enforce the Certificate Insurer's
rights or interests under this Agreement without limiting the rights or
affecting the interests of the Holders as otherwise set forth herein.

          Section 6.11 ALLOCATION OF LIQUIDATED LOAN LOSSES. Prior to each
Distribution Date the Servicer shall determine the total amount of related
Liquidated Loan Losses, if any, that occurred during the related Due Period with
respect to the Loans. The amount of such Liquidated Loan Losses shall be
evidenced by an Officer's Certificate to be delivered to the Trustee not later
than the Servicer Remittance Date. On each Distribution Date, the principal
portion of all Liquidated Loan Losses on the Mortgage Loans shall increase the
Subordination Deficit in the manner described in this Agreement.

          Section 6.12 PRE-FUNDING ACCOUNT.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain with itself one or more segregated trust accounts that are Eligible

Account the amount of any net loss incurred in respect of any such Permitted
Investment immediately upon realization of such loss without any right of
reimbursement therefor.

          (b) Amounts on deposit in the Pre-Funding Account shall be withdrawn
by the Trustee as follows:

          (i) On any Subsequent Transfer Date, the Trustee shall withdraw from
     the Pre-Funding Account and deposit into the Certificate Account an amount
     equal to 100% of the Principal Balances of the Subsequent Mortgage Loans
     transferred and assigned to the Trustee on such Subsequent Transfer Date
     and pay such amount to or upon the order of the Depositor upon satisfaction
     of the conditions set forth in Section 2.08(b) with respect to such
     transfer and assignment; and

          (ii) If the Pre-Funded Amount has not been reduced to zero during the
     Pre-Funding Period, on the Servicer Remittance Date immediately prior to
     the Distribution Date occurring in _______ 199__, the Trustee shall deposit
     into the Certificate Account any amounts remaining in the Pre-Funding
     Account.

          Section 6.13 CAPITALIZED INTEREST ACCOUNT.

          (a) No later than the Closing Date, the Trustee shall establish and
maintain with itself a separate, segregated trust account, which shall be an
Eligible Account, titled "Capitalized Interest Account,
_______________________________, as trustee for the registered holders of ACE

Interest Account").  The Trustee shall, promptly upon receipt, deposit in the
Capitalized Interest Account and retain therein the Initial Capitalized Interest
Amount remitted on the Closing Date to the Trustee by the Depositor.  In
addition, the Trustee shall deposit into the Capitalized Interest Account all
income and gain on investments in the Pre-Funding Account pursuant to Section
6.12. Funds deposited in the Capitalized Interest Account shall be 

                                       67

 
held in trust by the Trustee for the Holders of the Class A Certificates and the
Certificate Insurer for the uses and purposes set forth herein. For federal
income tax purposes, the Depositor shall be the owner of the Capitalized
Interest Account and shall report all items of income, deduction, gain or loss
arising therefrom. The Depositor shall deposit in the Capitalized Interest
Account the amount of any net loss incurred in respect of any such Permitted
Investment immediately upon realization of such loss without any right of
reimbursement therefor.

          (b) On each of the first ____ Distribution Dates, the Trustee shall

Class A Pass-Through Rate for such Distribution Date minus    % (B)    %, and
(iii) the number of days, up to a maximum of 30 per calendar month, from the
Subsequent Cut-off Date to ___________, 199__, shall be remitted, without

Class A-4 Certificates to zero, (ii) the termination of the Trust Fund in
accordance with Section 8.01 and (iii) the first Business Day following the

                                  ARTICLE VII

                                    DEFAULT

          Section 7.01 EVENTS OF DEFAULT. (a)"Event of Default", wherever used

          (i) any failure by the Servicer to remit to the Trustee any payment,
     other than a Servicing Advance, required to be made by the Servicer under

     perform in any material respect any other of the covenants or agreements on
     the part of the Servicer contained in this Agreement, or the failure of any
     representation and warranty made pursuant to Section 3.01 to be true and
     correct which continues unremedied for a period of 30 days (or 15 days in
     the case of a failure to pay the premium for any insurance policy which is
     required to be maintained under this Agreement) after the date on which
     written notice of such failure, requiring the same to be remedied, shall
     have been given to the Servicer, as the case may be, by the Depositor or
     the Trustee or to the Servicer and the Trustee by any Certificateholder or
     the Certificate Insurer;

          (iv) a decree or order of a court or agency or supervisory authority

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

          (vi) the Servicer shall admit in writing its inability to pay its
     debts 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.

          (b) If an Event of Default described in this Section shall occur,
then, and in each and every such case, so long as such Event of Default shall
not have been remedied the 

                                       69

 
Trustee shall, but only at the direction of the Certificate Insurer or the
Majority Certificateholders and with the prior written consent of the
Certificate Insurer, by notice in writing to the Servicer and a Responsible
Officer of the Trustee, and in addition to whatever rights such
Certificateholders may have at law or equity to damages, including injunctive
relief and specific performance, terminate all the rights and obligations of the
Servicer under this Agreement and in and to the Mortgage Loans and the proceeds
thereof, as servicer. Upon receipt by the Servicer of such written notice, all
authority and power of the Servicer under this Agreement, whether with respect
to the Mortgage Loans or otherwise, shall, subject to Section 7.02, pass to and
be vested in the Trustee or its designee approved by the Certificate Insurer and
the Trustee is hereby authorized and empowered to execute and deliver, on behalf
of the Servicer, as attorney-in-fact or otherwise, at the expense of the
Servicer, any and all documents and other instruments and do or cause to be done
all other acts or things necessary or appropriate to effect the purposes of such
notice of termination, including, but not limited to, the transfer and
endorsement or assignment of the Mortgage Loans and related documents. The
Servicer agrees to cooperate (and pay any related costs and expenses) with the
Trustee in effecting the termination of the Servicer's responsibilities and
rights hereunder, including, without limitation, the transfer to the Trustee or
its designee for administration by it of all amounts which shall at the time be
credited by the Servicer to the Collection Account or thereafter received with
respect to the Mortgage Loans. The Trustee shall promptly notify the Certificate
Insurer and the Rating Agencies of the occurrence of an Event of Default.

          Section 7.02 TRUSTEE TO ACT; APPOINTMENT OF SUCCESSOR. (a) On and
after the time the Servicer receives a notice of termination pursuant to Section
7.01, or the Trustee receives the resignation of the Servicer evidenced by an
Opinion of Counsel pursuant to Section 5.24, or the Servicer is removed as
Servicer pursuant to Article VII, in which event the Trustee shall promptly
notify the Rating Agencies, except as otherwise provided in Section 7.01, the
Trustee shall be the successor in all respects to the Servicer in its capacity
as servicer under this Agreement and the transactions set forth or provided for
herein and shall be subject to all the responsibilities, duties and liabilities
relating thereto placed on the Servicer by the terms and provisions hereof
arising on or after the date of succession; provided, however, that the Trustee
shall not be liable for any actions or the representations and warranties of any
servicer prior to it and including, without limitation, the obligations of the
Servicer set forth in Sections 2.04 and 3.03. The Trustee, as successor
servicer, or any other successor servicer shall be obligated to pay Compensating
Interest pursuant to Section 6.09 in any event and to make advances pursuant to
Section 5.21 unless, and only to the extent the Trustee as successor servicer
determines reasonably and in good faith that such advances would not be
recoverable pursuant to Sections 5.04(b), 5.04(g) or 5.04(j), such determination
to be evidenced by a certification of a Responsible Officer of the Trustee, as
successor servicer delivered to the Certificate Insurer.

          (b) Notwithstanding the above, the Trustee may, if it shall be
unwilling to so act, or shall, if it is unable to so act or if the Majority
Certificateholders with the consent of the Certificate Insurer or the
Certificate Insurer so requests in writing to the Trustee, appoint, pursuant to
the provisions set forth in paragraph (c) below, or petition a court of
competent jurisdiction to appoint, any established mortgage loan servicing
institution acceptable to the Certificate Insurer that has a net worth of not
less than $15,000,000 as the successor to the Servicer hereunder in the
assumption of all or any part of the responsibilities, duties or liabilities of
the Master Servicer hereunder.

                                       70

 
          (c) In the event the Trustee is the successor servicer, it shall be
entitled to Servicing Compensation (including the Servicing Fee as adjusted
pursuant to the definition thereof) and other funds pursuant to Section 5.14
hereof as the Servicer. In the event the Trustee is unable or unwilling to act
as successor servicer, the Trustee shall solicit, by public announcement, bids
from housing and home finance institutions, banks and mortgage servicing
institutions meeting the qualifications set forth above. Such public
announcement shall specify that the successor servicer shall be entitled to the
full amount of the aggregate Servicing Fees hereunder as servicing compensation,
together with the other Servicing Compensation. Within thirty days after any
such public announcement, the Trustee shall negotiate and effect the sale,
transfer and assignment of the servicing rights and responsibilities hereunder
to the qualified party submitting the highest qualifying bid. The Trustee shall
deduct from any sum received by the Trustee from the successor to the Master
Servicer in respect of such sale, transfer and assignment all costs and expenses
of any public announcement and of any sale, transfer and assignment of the
servicing rights and responsibilities hereunder and the amount of any
unreimbursed Servicing Advances and Periodic Advances owed to the Trustee. After
such deductions, the remainder of such sum shall be paid by the Trustee to the
Master Servicer at the time of such sale, transfer and assignment to the
Servicer's successor.

          (d) The Trustee and such successor shall take such action, consistent
with this Agreement, as shall be necessary to effectuate any such succession.
The Servicer agrees to cooperate with the Trustee and any successor servicer in
effecting the termination of the Servicer's servicing responsibilities and
rights hereunder and shall promptly provide the Trustee or such successor
servicer, as applicable, at the Servicer's cost and expense, all documents and
records reasonably requested by it to enable it to assume the Servicer's
functions hereunder and shall promptly also transfer to the Trustee or such
successor servicer, as applicable, all amounts that then have been or should
have been deposited in the Collection Account by the Servicer or that are
thereafter received with respect to the Mortgage Loans. Any collections received
by the Servicer after such removal or resignation shall be endorsed by it to the
Trustee and remitted directly to the Trustee or, at the direction of the
Trustee, to the successor servicer. Neither the Trustee nor any other successor
servicer shall be held liable by reason of any failure to make, or any delay in
making, any distribution hereunder or any portion thereof caused by (i) the
failure of the Servicer to deliver, or any delay in delivering, cash, documents
or records to it, or (ii) restrictions imposed by any regulatory authority
having jurisdiction over the Servicer hereunder. No appointment of a successor
to the Servicer hereunder shall be effective until the Trustee and the
Certificate Insurer shall have consented in writing thereto, and written notice
of such proposed appointment shall have been provided by the Trustee to the
Certificate Insurer and to each Certificateholder. The Trustee shall not resign
as servicer until a successor servicer reasonably acceptable to the Certificate
Insurer has been appointed.

          (e) Pending appointment of a successor to the Servicer hereunder, the
Trustee shall act in such capacity as hereinabove provided. In connection with
such appointment and assumption, the Trustee may make such arrangements for the
compensation of such successor out of payments on Mortgage Loans as it and such
successor shall agree; PROVIDED, HOWEVER, that no such compensation shall be in
excess of that permitted the Servicer pursuant to Section 5.14, together with
other Servicing Compensation. The Servicer, the Trustee and such successor shall
take such action, consistent with this Agreement, as shall be necessary to
effectuate any such succession.

                                       71

 
          Section 7.03 WAIVER OF DEFAULTS. The Majority Certificateholders may,
on behalf of all Certificateholders, and subject to the consent of the
Certificate Insurer, waive any events permitting removal of the Servicer as
servicer pursuant to this Article VII; provided, however, that the Majority
Certificateholders may not waive a default in making a required distribution on
a Certificate without the consent of the holder of such Certificate. Upon any
waiver of a past default, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereto except to the extent
expressly so waived. Notice of any such waiver shall be given by the Trustee to
the Rating Agencies.

          Section 7.04 MORTGAGE LOANS, TRUST FUND AND ACCOUNTS HELD FOR BENEFIT
OF THE CERTIFICATE INSURER. (a) The Trustee shall hold the Trust Fund and the
Mortgage Files for the benefit of the Certificateholders and the Certificate
Insurer and all references in this Agreement and in the Certificates to the
benefit of Holders of the Certificates shall be deemed to include the
Certificate Insurer. The Trustee shall cooperate in all reasonable respects with
any reasonable request by the Certificate Insurer for action to preserve or
enforce the Certificate Insurer's rights or interests under this Agreement and
the Certificates unless, as stated in an Opinion of Counsel addressed to the
Trustee and the Certificate Insurer, such action is adverse to the interests of
the Certificateholders or diminishes the rights of the Certificateholders or
imposes additional burdens or restrictions on the Certificateholders.

          (b) The Servicer hereby acknowledges and agrees that it shall service
the Mortgage Loans for the benefit of the Certificateholders and for the benefit
of the Certificate Insurer, and all references in this Agreement to the benefit
of or actions on behalf of the Certificateholders shall be deemed to include the
Certificate Insurer.

                                       72

 
                                  ARTICLE VIII

                                  TERMINATION

          Section 8.01 TERMINATION. (a) Subject to Section 8.02, this Agreement
shall terminate upon notice to the Trustee of either: (i) the disposition of all
funds with respect to the last Mortgage Loan and the remittance of all funds due
hereunder and the payment of all amounts due and payable to the Certificate
Insurer and the Trustee or (ii) mutual consent of the Servicer, the Certificate
Insurer and all Certificateholders in writing; provided, however, that in no
event shall the Trust Fund established by this Agreement terminate later than
twenty-one years after the death of the last surviving lineal descendant of
Joseph P. Kennedy, late Ambassador of the United States to the Court of St.
James, alive as of the date hereof.

          (b) In addition, subject to Section 8.02, the Servicer may, at its
option and at its sole cost and expense, terminate this Agreement on any date on
which the related Pool Principal Balance is less than 10% of the sum of (x) the
aggregate of the Principal Balances of the Mortgage Loans on the Cut-off Date
plus (y) the aggregate of the Principal Balances of the Subsequent Mortgage
Loans on their respective Subsequent Cut-off Dates, by purchasing, on the next
succeeding Distribution Date, all of the outstanding Mortgage Loans and REO
Properties at a price (the "Termination Price") equal to the sum of (i) 100% of
the Principal Balance of each such outstanding Mortgage Loan and each REO
Property, (ii) the aggregate amount of accrued and unpaid interest on such
Mortgage Loans through the related due period and 30 days' interest on such
Mortgage Loans at a rate equal to the related Mortgage Interest Rate (net of the
Servicing Fee) with respect to such Mortgage Loan, (iii) any unreimbursed
amounts due to the Certificate Insurer under this Agreement or the Insurance
Agreement, (iv) the amount of any unreimbursed Servicing Advances made by the
Servicer with respect to the related Mortgage Loans and (v) any excess of the
actual stated principal balance of each such Mortgage Loan and REO Property over
the Principal Balance thereof, the aggregate amount of accrued and unpaid
interest on such excess through the related due period and 30 days' interest on
such excess at a rate equal to the related Mortgage Interest Rate with respect
to each related Mortgage Loan.  Any such purchase shall be accomplished by
deposit into the Certificate Account of the Termination Price. From the
Termination Price so deposited, the Trustee shall reimburse the Servicer for the
amount of any unpaid Servicing Fees, unreimbursed Periodic Advances and
unreimbursed Servicing Advances made by the Servicer with respect to the related
Mortgage Loans. No such termination is permitted without the prior written
consent of the Certificate Insurer (i) if it would result in a draw on the
Certificate Insurance Policy or (ii) unless the Servicer shall have delivered to
the Certificate Insurer an opinion of counsel reasonably satisfactory to the
Certificate Insurer stating that no amounts paid hereunder are subject to
recapture as preferential transfers under the United States Bankruptcy Code, 11
U.S.C. ss.ss. 101 et seq., as amended.

          (c) If on any Distribution Date, the Servicer determines that there
are no outstanding Mortgage Loans and no other funds or assets in the Trust Fund
other than funds in the related Certificate Account, the Servicer shall send a
final distribution notice promptly to the related Certificateholders in
accordance with paragraph (d) below.

                                       73

 
          (d) Notice of any termination, specifying the Distribution Date upon
which the Trust Fund will terminate and that the Certificateholders shall
surrender their Certificates to the Trustee for payment of the final
distribution and cancellation, shall be given promptly by the Servicer by letter
to the Certificateholders mailed during the month of such final distribution
before the Master Servicer Remittance Date in such month, specifying (i) the
Distribution Date upon which final payment of the Certificates will be made upon
presentation and surrender of the Certificates at the office of the Trustee
therein designated, (ii) the amount of any such final payment and (iii) that the
Record Date otherwise applicable to such Distribution Date is not applicable,
payments being made only upon presentation and surrender of the Certificates at
the office of the Trustee therein specified. The Servicer shall give such notice
to the Trustee therein specified. The Servicer shall give such notice to the
Trustee at the time such notice is given to the Certificateholders. The
obligations of the Certificate Insurer hereunder shall terminate upon the
deposit by the Servicer with the Trustee of a sum sufficient to purchase all of
the Mortgage Loans and REO Properties in the Trust Fund as set forth above and
when the aggregate Security Balance of the Certificates has been reduced to
zero.

          (e) In the event that all Certificateholders do not surrender their
Certificates for cancellation within six months after the time specified in the
above-mentioned written notice, the Servicer shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, all of the Certificates shall not have been
surrendered for cancellation, the Trustee may take appropriate steps, or may
appoint an agent to take appropriate steps, to contact the remaining
Certificateholders concerning surrender of their Certificates and the cost
thereof shall be paid out of the funds and other assets which remain subject
hereto. If within nine months after the second notice all the Certificates shall
not have been surrendered for cancellation, the Class R Certificateholders shall
be entitled to all unclaimed funds and other assets which remain subject hereto
and the Trustee upon transfer of such funds shall be discharged of any
responsibility for such funds and the Certificateholders shall look only to such
Class R Certificateholders for payment. Such funds shall remain uninvested.

          Section 8.02 ADDITIONAL TERMINATION REQUIREMENTS. (a) In the event
that the Servicer exercises its purchase option with respect to the Trust Fund
as provided in Section 8.01, the Trust Fund shall be terminated in accordance
with the following additional requirements, unless the Trustee has been
furnished with an Opinion of Counsel to the effect that the failure of the Trust
Fund to comply with the requirements of this Section 8.02 will not (i) result in
the imposition of taxes on "prohibited transactions" of the Trust Fund as
defined in Section 860F of the Code or (ii) cause the Trust Fund to fail to
qualify as a REMIC at any time that any Class A Certificates are outstanding:

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

                                       74

 
          (ii) During 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 all of the assets of the Trust Fund for cash; and

          (iii) At the time of the making of the final payment on the
     Certificates, the Trustee shall distribute or credit, or cause to be
     distributed or credited, to the Holders of the Class R Certificates all
     cash on hand in the Trust Fund (other than cash retained to meet claims),
     and the REMIC shall terminate at that time.

          (b) By their acceptance of the Class R Certificates, the Holders
thereof hereby agree to authorize the Trustee to specify the 90-day liquidation
period for the Trust Fund, which authorization shall be binding upon all
successor Class R Certificateholders.

          Section 8.03 ACCOUNTING UPON TERMINATION OF SERVICER. Upon termination
of the Servicer, the Servicer shall, at its expense:

          (a) deliver to its successor or, if none shall yet have been
appointed, to the Trustee, the funds in any Account;

          (b) deliver to its successor or, if none shall yet have been
appointed, to the Trustee all of the Mortgage Files and related documents and
statements held by it hereunder and a Mortgage Loan portfolio computer tape;

          (c) deliver to its successor or, if none shall yet have been
appointed, to the Trustee and, upon request, to the Certificateholders a full
accounting of all funds, including a statement showing the Monthly Payments
collected by it and a statement of monies held in trust by it for the payments
or charges with respect to the Mortgage Loans; and

          (d) execute and deliver such instruments and perform all acts
reasonably requested in order to effect the orderly and efficient transfer of
servicing of the Mortgage Loans to its successor and to more fully and
definitively vest in such successor all rights, powers, duties,
responsibilities, obligations and liabilities of the "Servicer" under this
Agreement.

                                   ARTICLE IX

                             CONCERNING THE TRUSTEE

          Section 9.01 DUTIES OF TRUSTEE. The Trustee, prior to the occurrence
of an Event of Default and after the curing of all Events of Default which may
have occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement. If an Event of Default occurs and is
continuing, 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 its exercise
as a prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs. Any permissive right of the Trustee enumerated in
this Agreement shall not be construed as a duty.

          The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform on their face to the requirements of this Agreement; provided, however,
that the Trustee shall not be responsible for the accuracy or content of any
resolution, certificate, statement, opinion, report, document, order or other
instrument furnished by the Master Servicer or the Seller hereunder. If any such
instrument is found not to conform to the requirements of this Agreement in a
material manner, the Trustee shall take action as it deems appropriate to have
the instrument corrected and will provide notice thereof to the Certificate
Insurer.

          The Trustee shall sign on behalf of the Trust Fund any tax return that
the Trustee is required to sign pursuant to applicable federal, state or local
tax laws.

          The Trustee covenants and agrees that it shall perform its obligations
hereunder in a manner so as to maintain the status of the Trust Fund as a REMIC
under the REMIC Provisions and to prevent the imposition of any federal, state
or local income, prohibited transaction, contribution or other tax on the Trust
Fund 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.

          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 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 the Trustee and conforming
     to the requirements of this Agreement;

                                       76

 
          (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 Certificate Insurer relating to the
     time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Agreement.

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

          (a) The Trustee may request and rely upon and shall be protected in
     acting or refraining from acting upon any resolution, Officers'
     Certificate, Opinion of Counsel, 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;

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

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

          (d) 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;

          (e) Prior to the occurrence of an Event of Default hereunder and after
     the curing of all Events of Default which may have occurred, the Trustee
     shall not be bound to make any investigation into the facts or matters
     stated in any resolution, certificate, statement, instrument, opinion,
     report, notice, request, consent, order, approval, bond or other paper or
     document, unless requested in writing to do so by the Certificate Insurer
     or by at least a 25% Percentage Interest of any Class of Class A
     Certificates; provided, however, that if the payment within a reasonable
     time to the Trustee of the costs, expenses or liabilities likely to be
     incurred by it in the making of such 

                                       77

 
     investigation is, in the opinion of the Trustee, not reasonably assured to
     the Trustee by such Certificateholders, the Trustee may require reasonable
     indemnity against such expense, or liability from such Certificateholders
     as a condition to taking any such action;

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

          (g) 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; and

          (h) The Trustee shall not be required to give any bond or surety in
     respect of the execution of the Trust created hereby or the powers granted
     hereunder.

          Section 9.03 TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS.
The recitals contained herein and in the Certificates, other than the signature
of the Trustee on the Certificates and the certificate of authentication, shall
be taken as the statements of the Depositor or the Servicer, as the case may be,
and the Trustee assumes no responsibility for their correctness. The Trustee
makes no representations or warranties as to the validity or sufficiency of this
Agreement or of the Certificates or of any Mortgage Loan or related document,
other than the signature of the Trustee on the Certificates and the Certificate
of Authentication. The Trustee shall not be accountable for the use or
application by the Depositor or the 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 Seller in respect of the Mortgage Loans or deposited in or withdrawn
from the Custodial Account or the Certificate Accounts or any other account by
or on behalf of the Depositor or the Servicer, other than any funds held by or
on behalf of the Trustee in accordance with Section 6.01.

          Section 9.04 TRUSTEE MAY OWN CERTIFICATES. The Trustee in its
individual or any other capacity may become the owner or pledgee of Certificates
with the same rights it would have if it were not Trustee.

          Section 9.05 PAYMENT OF TRUSTEE'S FEES. The Trustee shall withdraw
from the Certificate Account on each Distribution Date and pay to itself the
Trustee's Fee. Except as otherwise provided in this Agreement, the Trustee and
any director, officer, employee or agent of the Trustee shall be indemnified by
the Trust Fund and held harmless against any loss, liability or "unanticipated"
out-of-pocket expense incurred or paid to third parties (which expenses shall
not include salaries paid to employees, or allocable overhead, of the Trustee)
in connection with the acceptance or administration of its trusts hereunder or
the Certificates, or its performance under the Insurance Agreement, other than
any loss, liability or expense incurred by reason of willful misfeasance, bad
faith or negligence in the performance of duties hereunder or under the
Insurance Agreement or by reason of reckless disregard of obligations and duties
hereunder or under the Insurance Agreement. All such amounts shall be payable
from funds in the Certificate Accounts as provided in Section 6.02(e). The
provisions of this Section 9.05 shall survive the termination of this Agreement
and the removal or resignation of the Trustee.

                                       78

 
          The Servicer covenants and agrees to indemnify the Trustee and any
director, officer, employee or agent of the Trustee against any losses,
liabilities, damages, claims or expenses (including reasonable legal fees and
such related expenses) that may be sustained by the Trustee in connection with
this Agreement related to the willful misfeasance, bad faith or negligence in
the performance of the Servicer's duties hereunder.

          Section 9.06 ELIGIBILITY REQUIREMENTS FOR TRUSTEE. The Trustee
hereunder shall at all times be a corporation or a national banking association
organized and doing business under the laws of any state or the United States of
America or the District of Columbia, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$50,000,000 and subject to supervision or examination by federal or state
authority. In addition, the Trustee shall at all times be acceptable to the
Rating Agencies rating the Certificates. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section the combined capital and surplus of such corporation shall be deemed to
be its combined capital and surplus as set forth in its most recent report of
condition so published. In case at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect specified in Section 9.07.
The corporation or national banking association serving as Trustee may have
normal banking and trust relationships with the Seller and their affiliates or
the  Servicer and its affiliates; provided, however, that such corporation
cannot be an affiliate of the  Servicer other than the Trustee in its role as
successor to the  Servicer.

          Section 9.07 RESIGNATION AND REMOVAL OF THE TRUSTEE. The Trustee may
at any time resign and be discharged from the trusts hereby created by giving
notice thereof to the Depositor, the Certificate Insurer, the  Servicer and to
all Certificateholders; provided, that such resignation shall not be effective
until a successor trustee is appointed and accepts appointment in accordance
with the following provisions. Upon receiving such notice of resignation, the
Servicer shall, with the written consent of the Certificate Insurer, promptly
appoint a successor trustee who meets the eligibility requirements of Section
9.06 by written instrument, in duplicate, which instrument shall be delivered to
the resigning Trustee and to the successor trustee. A copy of such instrument
shall be delivered to the Certificateholders, the Certificate Insurer and the
Servicer by the Depositor. If no successor trustee shall have been so appointed
and have accepted appointment within 60 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; provided, however, that
the resigning Trustee shall not resign and be discharged from the trusts hereby
created until such time as the Rating Agency rating the Certificates approves
the successor trustee.

          If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.06 and shall fail to resign after written
request therefor by the Servicer or the Certificate Insurer, 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, or if the rating of the long-term debt obligations of the Trustee
is not acceptable to the Rating Agencies in respect of mortgage pass-through
certificates having a rating equal to the then current rating on the

                                       79

 
Certificates, then the  Servicer, with the written consent of the Certificate
Insurer, may remove the Trustee and appoint a successor trustee who meets the
eligibility requirements of Section 9.06 by written instrument, in duplicate,
which instrument shall be delivered to the Trustee so removed and to the
successor trustee. A copy of such instrument shall be delivered to the
Certificateholders, the Certificate Insurer and the Depositor by the  Servicer.

          The Majority Certificateholders, with the written consent of the
Certificate Insurer, may at any time remove the Trustee and appoint a successor
trustee by written instrument or instruments, in triplicate, signed by the
Certificate Insurer or such Holders or their attorneys-in-fact duly authorized,
one complete set of which instruments shall be delivered to the  Servicer, one
complete set to the Trustee so removed and one complete set to the successor so
appointed. A copy of such instrument shall be delivered to the
Certificateholders, the Certificate Insurer and the Depositor by the  Servicer.

          Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section shall not
become effective until acceptance of appointment by the successor trustee as
provided in Section 9.08.

          Section 9.08 SUCCESSOR TRUSTEE. Any successor trustee appointed as
provided in Section 9.07 shall execute, acknowledge and deliver to the
Servicer, the Certificate Insurer and to its predecessor trustee an instrument
accepting such appointment hereunder, and thereupon the resignation or removal
of the predecessor trustee shall become effective and such successor trustee,
without any further act, deed or conveyance, shall become fully vested with all
the rights, powers, duties and obligations of its predecessor hereunder, with
the like effect as if originally named as trustee herein. The predecessor
trustee shall deliver to the successor trustee all of the Mortgage Files and
related documents and statements held by it hereunder, and the  Servicer and the
predecessor trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in the successor trustee all such rights, powers, duties and
obligations.

          No successor trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 9.06.

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

          Notwithstanding anything to the contrary contained herein, so long as
no Certificate Insurer Default exists, the appointment of any successor trustee
pursuant to any provision of this Agreement will be subject to the prior written
consent of the Certificate Insurer.

                                       80

 
          Section 9.09 MERGER OR CONSOLIDATION OF TRUSTEE. Any corporation into
which the Trustee may be merged or converted or with which it may be
consolidated or any corporation resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any corporation
succeeding to the business of the Trustee, shall be the successor of the Trustee
hereunder, provided such corporation shall be eligible under the provisions of
Section 9.06, without the execution or filing of any paper or any further act on
the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

          Section 9.10 APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE.
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust Fund or property securing the same may at the time be located, the
Depositor 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
9.10, such powers, duties, obligations, rights and trusts as the Depositor and
the Trustee may consider necessary or desirable. If the Depositor 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 9.06 hereunder and no notice to Holders of
Certificates of the appointment of co-trustee(s) or separate trustee(s) shall be
required under Section 9.08 hereof.

          In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.10 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.

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

                                       81

 
          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.

                                       82

 
                                   ARTICLE X

                                REMIC PROVISIONS

          Section 10.01  REMIC ADMINISTRATION.

          (a) The Trustee shall make an election to treat the Trust Fund
(exclusive of the Capitalized Interest Account and the Pre-Funding Account) as a
REMIC under the Code, and if necessary, under applicable state law. Such
election will be made on Form 1066 or other appropriate federal tax or
information return 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 election in respect of the Trust Fund, (i) each Class of
Class A Certificates shall be designated as the "regular interests" and the
Class R Certificates shall be designated as the sole Class of "residual
interest" in the REMIC. The Trustee shall not permit the creation of any
"interests" in the Trust Fund (within the meaning of Section 860G of the Code)
other than the REMIC regular interests and the interests represented by the
Certificates.

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

          (c) The Trustee shall pay out of its own funds, without any right of
reimbursement, any and all expenses relating to any tax audit of the Trust Fund
(including, but not limited to, any professional fees or any administrative or
judicial proceedings with respect thereto that involved the Internal Revenue
Service or state tax authorities), other than the expense of obtaining any tax
related Opinion of Counsel not obtained in connection with such an audit and
other than taxes, in either case except as specified herein; provided, however,
that if such audit resulted from the negligence of the  Servicer or the
Depositor, then the  Servicer or the Depositor, as the case may be, shall pay
such expenses. The Trustee, as agent for the tax matters person, shall (i) act
on behalf of the Trust Fund 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 Holder of the largest Percentage
Interest in the Class R Certificates from time to time is hereby designated as
Tax Matters Person with respect to the Trust Fund and hereby irrevocably
appoints and authorizes the Trustee to act its agent to perform the duties of
the Tax Matters Person with respect to the Trust Fund. To the extent authorized
under the Code and the regulations promulgated thereunder, each Holder of a
Class R Certificate hereby irrevocably appoints and authorizes the Trustee to be
its attorney-in-fact for purposes of signing any Tax Returns required to be
filed on behalf of the Trust Fund.

          (d) The Trustee shall prepare or cause to be prepared, sign and file
all of the Tax Returns in respect of the Trust Fund created hereunder, other
than Tax Returns required to be filed by the Servicer pursuant to Section 5.25.
The expenses of preparing and filing such returns shall be borne by the Trustee
without any right of reimbursement therefor.

          (e) The Trustee shall perform on behalf of the Trust Fund all
reporting and other tax compliance duties that are the responsibility of the
Trust Fund under the Code, REMIC Provisions or other compliance guidance issued
by the Internal Revenue Service or any state or local taxing authority. Among
its other duties, as required by the Code, the 

                                       83

 
REMIC Provisions or other such compliance guidance, the Trustee shall provide
(i) to any Transferor of a Class R Certificate and to the Internal Revenue
Service 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 Disqualified
Organization, (ii) to Certificateholders such information or reports as are
required by the Code or the REMIC Provisions including reports relating to
interest, original issue discount and market discount or premium and (iii) to
the Internal Revenue Service the name, title, address and telephone number of
the person who will serve as the representative of the Trust Fund. In addition,
the Depositor shall provide or cause to be provided to the Trustee, within ten
(10) days after the Closing Date, all information or data that the Trustee
reasonably determines to be relevant for tax purposes as to the valuations and
issue prices of the Certificates, including, without limitation, the price,
yield, prepayment assumption and projected cash flow of the Certificates.

          (f) The Trustee shall take such action and shall cause the Trust Fund
created hereunder to take such action as shall be necessary to create or
maintain the status thereof as a REMIC under the REMIC Provisions (and the
Master Servicer shall assist it, to the extent reasonably requested by it). The
Trustee shall not take any action, cause the Trust Fund to take any action or
fail to take (or fail to cause to be taken) any action that, under the REMIC
Provisions, if taken or not taken, as the case may be, could (i) endanger the
status of the Trust Fund as a REMIC or (ii) 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 set forth in Section 860G(d) of the Code) (either such
event, an "Adverse REMIC Event") unless the Trustee received an Opinion of
Counsel (at the expense of the party seeking to take such action but in no event
shall such Opinion of Counsel be an expense of the Trustee) to the effect that
the contemplated action will not, with respect to the Trust Fund created
hereunder, endanger such status or result in the imposition of such a tax. The
Servicer shall not take or fail to take any action (whether or not authorized
hereunder) as to which the Trustee has advised it in writing that it has
received an Opinion of Counsel (which such Opinion of Counsel shall not be an
expense of the Trustee) to the effect that an Adverse REMIC Event could occur
with respect to such action. In addition, prior to taking any action with
respect to the Trust Fund or its assets, or causing the Trust Fund to take any
action which is not expressly permitted under the terms of this Agreement, the
Servicer will consult with the Trustee or its designee, in writing, with respect
to whether such action could cause an Adverse REMIC Event to occur with respect
to the Trust Fund, and the  Servicer shall not take any such action or cause the
Trust Fund to take any such action as to which the Trustee has advised it in
writing that an Adverse REMIC Event could occur. The Trustee may consult with
counsel to make such written advice, and the cost of same shall be borne by the
party seeking to take the action not permitted by this Agreement (but in no
event shall such cost be an expense of the Trustee). At all times as may be
required by the Code, the Trustee will ensure that substantially all of the
assets of the Trust Fund will consist of "qualified mortgages" as defined in
Section 860G(a)(3) of the Code and "permitted investments" as defined in Section
860G(a)(5) of the Code.

          (g) In the event that any tax is imposed on "prohibited transactions"
of the Trust Fund created hereunder as defined in Section 860F(a)(2) of the Code
on "net income from foreclosure property" of the Trust Fund as defined in
Section 860G(c) of the Code, on any contributions to the Trust Fund 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 

                                       84

 
local tax laws, such tax shall be charged (i) to the Trustee pursuant to Section
10.03 hereof, if such tax arises out of or results from a breach by the Trustee
of any of its obligations under this Article X, (ii) to the Master Servicer
pursuant to Section 10.03 hereof, if such tax arises out of or results from a
breach by the Master Servicer of any of its obligations under Article V or this
Article X, or otherwise (iii) against amounts on deposit in the related
Certificate Account and shall be paid by withdrawal therefrom.

          (h) On or before April 15 of each calendar year, commencing April 15,
1997, the Trustee shall deliver to the Servicer and each Rating Agency a
Certificate from a Responsible Officer of the Trustee stating the Trustee's
compliance with this Article X.

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

          (j) The Trustee shall not accept any contributions of assets to the
Trust Fund unless it shall have received an Opinion of Counsel (which such
Opinion of Counsel shall not be an expense of the Trustee) to the effect that
the inclusion of such assets in the Trust Fund will not cause the Trust Fund to
fail to qualify as a REMIC at any time that any Certificates are outstanding or
subject the Trust Fund to any tax under the REMIC Provisions or other applicable
provisions of federal, state and local law or ordinances.

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

          (l) Solely for purposes of satisfying Section 1.860G-1(a)(4)(iii) of
the Treasury Regulations, the "latest possible maturity date" of the Class A
Certificates is ___________ 25, 20__.

          (m) Upon filing with the Internal Revenue Service, the Trustee shall
furnish to the Holders of the Class R Certificates the Form 1066 and each Form
1066Q.

                            MISCELLANEOUS PROVISIONS

          Section 11.01 LIMITATION ON LIABILITY OF THE DEPOSITOR AND THE
SERVICER. Neither the Depositor, the Servicer nor any of the directors,
officers, employees or agents of the Depositor or the Servicer shall be under
any liability to the Certificate Insurer, the Trust Fund or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that this provision shall not protect the Depositor or the
Servicer (but this provision shall protect the above described persons) against
any breach of warranties or representations made herein, or against any specific
liability imposed on the Servicer or the Depositor pursuant to any other Section
hereof; and provided further that this provision shall not protect the
Depositor, the Servicer or any such person, against any liability which would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in the performance of duties or by reason of reckless disregard of obligations
and duties hereunder. The Depositor, the Servicer and any director, officer,
employee or agent of the Depositor or the Servicer may rely in good faith on any
document of any kind prima facie properly executed and submitted by any Person
respecting any matters arising hereunder. The Depositor, the Servicer and any
director, officer, employee or agent of the Depositor or the Master Servicer
shall be indemnified and held harmless by the Trust Fund against any loss,
liability or expense incurred in connection with any legal action relating to
this Agreement or the Certificates, other than any loss, liability or expense
related to Servicer's servicing obligations with respect to any specific
Mortgage Loan or Mortgage Loans (except as any such loss, liability or expense
shall be otherwise reimbursable pursuant to this Agreement) or related to the
Servicer's obligations under this Agreement, or 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 Depositor nor the 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
Depositor or the Servicer may in its sole discretion undertake any such action
which it may deem necessary or desirable with respect to this Agreement and the
rights and duties of the parties hereto and the interests of the
Certificateholders hereunder. In the event the Depositor or the Servicer take
any action as described in the preceding sentence, the legal expenses and costs
of such action, if previously approved in writing by the Certificate Insurer,
which approval shall not be unreasonably withheld, and any liability resulting
therefrom will be expenses, costs and liabilities of the Trust Fund, and the
Servicer or the Depositor, as the case may be, will be entitled to be reimbursed
therefor out of funds in the Collection Account.

          Section 11.02 ACTS OF CERTIFICATEHOLDERS. (a) Except as otherwise
specifically provided herein, whenever Certificateholder action, consent or
approval is required under this Agreement, such action, consent or approval
shall be deemed to have been taken or given on behalf of, and shall be binding
upon, all Certificateholders if the Majority Certificateholders or the
Certificate Insurer agrees to take such action or give such consent or approval.

                                       87

 
          (b) 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 heir to claim an accounting or to
take any action or proceeding in any court for a partition or winding up of the
Trust Fund, nor otherwise affect the rights, obligations and liabilities of the
parties hereto or any of them.

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

          Section 11.03 AMENDMENT. This Agreement may be amended from time to
time by the Depositor, the Servicer and the Trustee without the consent of any
of the Certificateholders, (i) to cure any ambiguity or mistake, (ii) to
correct, modify or supplement any provisions herein which may be inconsistent
with any other provisions herein, (iii) to make any other provisions with
respect to matters or questions arising under this Agreement which are not
materially inconsistent with the provisions hereof amend this Agreement in any
respect subject to the provisions below, or (iv) if such amendment, as evidenced
by an Opinion of Counsel (provided by the Person requesting such amendment)
delivered to the Trustee, is reasonably necessary to comply with any
requirements imposed by the Code or any successor or amendatory statute or any
temporary or final regulation, revenue ruling, revenue procedure or other
written official announcement or interpretation relating to federal income tax
laws or any proposed such action which, if made effective, would apply
retroactively to the Trust Fund at least from the effective date of such
amendment; provided that in the case of clause (iii) such action shall not
adversely affect in any material respect the interests of any Certificateholder
(other than Certificateholders who shall consent to such amendment) or the
Certificate Insurer, as evidenced either by an Opinion of Counsel (provided by
the Person requesting such amendment) or written notification from each Rating
Agency to the effect that such amendment will not cause such Rating Agency to
lower or withdraw the then current ratings on the Certificates, delivered to the
Trustee and the Certificate Insurer.

          This Agreement may also be amended from time to time by the Depositor,
the Servicer and the Trustee with the consent of the Certificate Insurer and the
Majority Certificateholders for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Agreement or
of modifying in any manner the rights of the Holders of Certificates; provided,
however, that no such amendment shall (i) reduce in any manner the amount of, or
delay the timing of, payments received on Mortgage Loans which are required to
be distributed on any Certificate without the consent of the Holder of such
Certificate or (ii) reduce the aforesaid percentage of Certificates the Holders
of which are required to consent to any such amendment, without the consent of
the Certificate Insurer and the Holders of all Certificates then outstanding.
Notwithstanding any other provision of this Agreement, for purposes of the
giving or withholding of consents pursuant to this Section 11.03, Certificates
registered in the name of the Depositor or the Servicer or any affiliate thereof
shall be entitled to voting rights with respect to matters described in (i),
(ii) and (iii) of this paragraph.

                                       88

 
          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 (provided by the Person requesting such
amendment) to the effect that such amendment will not result in the imposition
of any tax on the Trust Fund pursuant to the REMIC Provisions or cause the Trust
Fund to fail to qualify as a REMIC at any time that any of the Certificates are
outstanding.

          Promptly after the execution of any such amendment the Trustee shall
furnish a statement describing the amendment to each Certificateholder, the
Certificate Insurer, and each Rating Agency.

          It shall not be necessary for the consent of Certificateholders under
this Section 11.03 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.

          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.

          Section 11.04 RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement, or a memorandum thereof if permitted under
applicable law, is subject to recordation in all appropriate public offices for
real property records in all of the counties or other comparable jurisdictions
in which any or all of the 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 at the Certificateholders' expense on
direction and at the expense of Majority Certificateholders requesting such
recordation, but only when accompanied by an Opinion of Counsel to the effect
that such recordation materially and beneficially affects the interests of the
Certificateholders or is necessary for the administration or servicing of the
Mortgage Loans.

Pooling and Servicing Agreement dated as specified above (the "Agreement") among
the Depositor, ______________, as servicer (the "Servicer"), and
_________________, as trustee (the "Trustee"), a summary of certain of the

          All distributions on this Certificate will be made or caused to be

          This Certificate is one of a duly authorized issue of Certificates
issued in __________ Classes designated as Asset Backed Certificates of the
Series specified hereon (herein collectively called the "Certificates").

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

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

          The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Depositor, the Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Depositor, the
Servicer and the Trustee with the consent of the Certificate Insurer and the
Majority Certificateholders. Any such consent by the holder of this Certificate
shall be conclusive and binding on such holder and upon all future holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon the Certificate. The Agreement also permits the amendment thereof in
certain circumstances without the consent of the holders of any of the
Certificates and, in certain additional circumstances, without the consent of
the holders of certain Classes of Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Certificate Register upon surrender of this Certificate for registration of
transfer at the offices or agencies appointed by the Trustee 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 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.



                                       3


 
          The Depositor, the Servicer, the Trustee and the Certificate Registrar
and any agent of the Depositor, the 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 Depositor, the 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 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 (ii) the purchase by the Servicer from the
Trust Fund of all remaining Mortgage Loans, thereby effecting early retirement
of the Class [A-1][A-2][A-3][A-4] Certificates. The Agreement permits, but does
not require, the Servicer to purchase at a price determined as provided in the
Agreement all remaining Mortgage Loans; provided, that any such option may only
be exercised if the Pool Principal Balance as of the Distribution Date upon
which the proceeds of any such purchase are distributed is less than 10% of the
Original Pool Principal Balance (net of any excess of the Original Pre-Funded
Amounts over the aggregate of the Principal Balances of the Subsequent Mortgage
Loans as of their respective Subsequent Cut-off Dates).

          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.

          evidencing a percentage interest in any distributions allocable to the
          Class R Certificates with respect to a Trust Fund consisting primarily
          of a pool of conventional one- to four-family fixed rate first lien
          and second lien residential mortgage loans sold by ACE Securities
          Corp.

          This certifies that ____________________________ is the registered
owner of the Percentage Interest evidenced by this Certificate in certain
distributions with respect to a Trust Fund consisting primarily of a pool of
conventional one- to four-family fixed rate first lien and second lien
residential mortgage loans (the "Mortgage Loans"), sold by ACE Securities Corp.
(the "Depositor"). The Trust Fund was created pursuant to a Pooling and
Servicing Agreement dated as specified above (the "Agreement") among the
Depositor, ___________________________, as servicer (the "Servicer") and
_____________________________, as trustee (the "Trustee"), a summary of certain
of the pertinent provisions of which is set forth hereafter. To the extent not
defined herein, the capitalized terms used herein have the meanings assigned in
the Agreement. This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

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

          Pursuant to the terms of the Agreement, a distribution will be made on
the 25th day of each month or, if such 25th day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing as
described in the Agreement, to the Person in whose name this Certificate is
registered at the close of business on the last Business Day 



                                       3


 
immediately preceding the month of such Distribution Date (the "Record Date"),
from the Available Funds in an amount equal to the product of the Percentage
Interest evidenced by this Certificate and the amount (of interest and
principal, if any) required to be distributed to Holders of Class [R]
Certificates on such Distribution Date.

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

          No transfer of any Class R Certificate shall be made unless that
transfer is made pursuant to an effective registration statement under the 1933
Act and effective registration or qualification under applicable state
securities laws, or is made in a transaction which does not require such
registration or qualification. In the event that a transfer is to be made
without such registration or qualification, (a) the Trustee and the Depositor
shall require the transferee to execute an investment letter, which investment
letter shall not be an expense of the Depositor, the Servicer or the Trustee and
(b) in the event that such a transfer is not made pursuant to Rule 144A under
the Act, the Trustee shall require an Opinion of Counsel satisfactory to the
Trustee and the Depositor that such transfer may be made without such
registration or qualification, which Opinion of Counsel shall not be an expense
of the Depositor, the Trustee or the Servicer. Neither the Depositor nor the
Trustee is obligated to register or qualify any of the Class [R] Certificates
under the 1933 Act or any other securities law or to take any action not
otherwise required under the Agreement to permit the transfer of such
Certificates without registration or qualification. Any such Certificateholder
desiring to effect such transfer shall, and does hereby agree to, indemnify the
Trustee, the Depositor and the Servicer against any liability that may result if
the transfer is not so exempt or is not made in accordance with such federal and
state laws.

          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. The Percentage Interest this Certificate is set
forth above. Notwithstanding the fact this Certificate has no Certificate
Principal Balance, this Certificate will remain outstanding under the Agreement
and the Holder hereof may have additional obligations with respect to this
Certificate, including tax liabilities, and may be entitled to certain
additional distributions hereon, in accordance with the terms and provisions of
the Agreement.

          The Certificates are limited in right of payment to certain

be made by the Servicer from time to time for purposes other than distributions
to Certificateholders, such purposes including without limitation reimbursement
to the Depositor and the Servicer of advances made, or certain expenses
incurred, by either of them.

          The Agreement permits, with certain exceptions therein provided, the
amendment of the Agreement and the modification of the rights and obligations of
the Depositor, the Servicer and the Trustee and the rights of the
Certificateholders under the Agreement at any time by the Depositor, the
Servicer and the Trustee with the consent of the Certificate Insurer and the
Majority Certificateholders. Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Holder and upon all future holders of
this Certificate and of any Certificate issued upon the transfer hereof or in
exchange herefor or in lieu hereof whether or not notation of such consent is
made upon the Certificate. The Agreement also permits the amendment thereof in
certain circumstances without the consent of the Holders of any of the
Certificates and, in certain additional circumstances, without the consent of
the Holders of certain Classes of Certificates.

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

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.


                                       5


 
          The Depositor, the Servicer, the Trustee and the Certificate Registrar
and any agent of the Depositor, the 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 Depositor, 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 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 (ii) the purchase by the Servicer from the
Trust Fund of all remaining Mortgage Loans, thereby effecting early retirement
of the Class R Certificates. The Agreement permits, but does not require, such
Class R Certificateholder, the Servicer or the Certificate Insurer, as
applicable, to purchase at a price determined as provided in the Agreement all
remaining Mortgage Loans; provided, that any such option may only be exercised
if the Pool Principal Balance as of the Distribution Date upon which the
proceeds of any such purchase are distributed is less than 10% of the Original
Pool Principal Balance.

          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.

                    FORM OF TRANSFER AFFIDAVIT AND AGREEMENT

State of ___________  )

              )  ss.:

County of __________  )

          [NAME OF OFFICER], being first duly sworn, deposes and says:

          1. That he is [Title of Officer] of [Name of Owner] (record or
beneficial owner of the Asset Backed Certificates, Series 199__-__, Class R (the
"Owner")), a [savings institution] [corporation] duly organized and existing
under the laws of [the State of __________________] [the United States], on
behalf of which he makes this affidavit and agreement.

          2. That the Owner (i) is not and will not be a "disqualified
organization" as of [date of transfer] within the meaning of Section 860E(e)(5)
of the Internal Revenue Code of 1986, as amended (the "Code"), (ii) will
endeavor to remain other than a disqualified organization for so long as it
retains its ownership interest in the Class R Certificates, and (iii) is
acquiring the Class R Certificates for its own account or for the account of
another Owner from which it has received an affidavit and agreement in
substantially the same form as this affidavit and agreement. (For this purpose,
a "disqualified organization" means the United States, any state or political
subdivision thereof, any agency or instrumentality of any of the foregoing
(other than an instrumentality all of the activities of which are subject to tax
and, except for 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 Certificates to disqualified organizations under the Code,
that applies to all transfers of Class R 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] Certificates may be "noneconomic
residual interests" within the meaning of Treasury regulations promulgated
pursuant to the Code and that the transferor of a noneconomic residual interest
will remain liable for any taxes due with respect to the income on such residual
interest, unless no significant purpose of the transfer was to impede the
assessment or collection of tax.

          4. That the Owner is aware that the Trustee will not register the
transfer of any Class R Certificates unless the transferee, or the transferee's
agent, delivers to it an affidavit 

 
and agreement, among other things, in substantially the same form as this
affidavit and agreement. The Owner expressly agrees that it will not consummate
any such transfer if it knows or believes that any of the representations
contained in such affidavit and agreement are false.

          5. That the Owner has reviewed the restrictions set forth on the face
of the Class R Certificates and the provisions of Section 4.02(i) of the Pooling
and Servicing Agreement under which the Class R Certificates were issued (in
particular, clause (g) and (h) of Section 4.02(i) which authorize the Trustee to
deliver payments to a person other than the Owner in the event the Owner holds
such Certificates in violation of Section 4.02(i)). The Owner expressly agrees
to be bound by and to comply with such restrictions and provisions.

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

          7.  The Owner's Taxpayer Identification Number is ___________.

          8. This affidavit and agreement relates only to the Class R
Certificates held by the Owner and not to any other holder of the Class R
Certificates. The Owner understands that the liabilities described herein relate
only to the Class R Certificates.

          9. That no purpose of the Owner relating to the transfer of any of the
Class R Certificates by the Owner is or will be to impede the assessment or
collection of any tax.

          10. 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 Certificate
that the Owner intends to pay taxes associated with holding such Class R
Certificate as they become due, fully understanding that it may incur tax
liabilities in excess of any cash flows generated by the Class R Certificate.

          11. That the Owner has no present knowledge or expectation that it
will become insolvent or subject to a bankruptcy proceeding for so long as any
of the Class R Certificates remain outstanding.

          12. 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, 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 jurisdiction over the administration of such trust and one or more
persons described in this Paragraph 12 controls all substantial decisions of
such trust.



                                       2

 
          IN WITNESS WHEREOF, the Owner has caused this instrument to be
executed on its behalf, pursuant to the authority of its Board of Directors, by
its [Title of Officer] and its corporate seal to be hereunto attached, attested
by its [Assistant] Secretary, this ____ day of _______________, 199__.

Attention:  ACE Securities Corp. Series 199__-__

            Re:  ASSET BACKED CERTIFICATES, SERIES 199__-__

Ladies and Gentlemen:

          This letter is delivered to you in connection with the transfer by
_______________________________ (the "Seller") to ________________________ 
(the "Purchaser") of a ____% Percentage Interests of Asset Backed Certificates,
Series 199__-__, Class R Certificates (the "Certificates"), pursuant to 
Section 4.02 of the Pooling and Servicing Agreement (the "Pooling and 
Servicing Agreement"), dated as of __________, 199__, among ACE Securities 
Corp., as seller (the "Depositor"), ______________________, as Servicer, 
and ______________________, 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 Depositor and the Trustee that:

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

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

          3. The Seller has at the time of the transfer conducted a reasonable
investigation of the financial condition of the Purchaser as contemplated by
Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result of that
investigation, the Seller has determined that the Purchaser has historically
paid its debts as they 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
Certificate may not be respected for United States income tax purposes (and the
Seller may continue to be liable for United States income taxes associated
therewith) unless the Seller has conducted such an investigation.

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

 
                              Very truly yours,

[Trustee]

          Re:  ACE Securities Corp. Asset Backed Certificates, Series 199__-__

Ladies and Gentlemen:

          _______________________(the "Purchaser") intends to purchase from
____________________ (the "Seller"), a ____% Percentage Interest of Asset Backed
Certificates, Series 199__-__, Class _____ (the "Certificates"), issued pursuant
to the Pooling and Servicing Agreement (the "Pooling and Servicing Agreement"),
dated as of ____________, 199__ among ACE Securities Corp., as depositor (the
"Depositor"), ______________________________, as servicer, and
_________________________, 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 Depositor 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 Depositor 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.

          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 copy of the Pooling and Servicing Agreement and such other

 
     information concerning the Certificates, the Mortgage Loans and the
     Depositor as has been requested by the Purchaser from the Depositor 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 Depositor or the Seller to the satisfaction of the
     Purchaser. If the Purchaser did not purchase the Certificates from the
     Seller in connection with the initial distribution of the Certificates and
     was provided with a copy of the Private Placement Memorandum (the
     "Memorandum") relating to the original sale (the "Original Sale") of the
     Certificates by the Depositor, the Purchaser acknowledges that such
     Memorandum was provided to it by the Seller, that the Memorandum was
     prepared by the Depositor solely for use in connection with the Original
     Sale and the Depositor 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
     Depositor with respect to any damage, liability, claim or expense arising
     out of, resulting from or in connection with (a) error or omission, or
     alleged error or omission, contained in the Memorandum, or (b) any
     information, development or event arising after the date of the Memorandum.

          5. The Purchaser has not and will not nor has it authorized or will it
     authorize any person to (a) offer, pledge, sell, dispose of or otherwise
     transfer any Certificate, any interest in any Certificate or any other
     similar security to any person in any manner, (b) solicit any offer to buy
     or to accept a pledge, disposition of other transfer of any Certificate,
     any interest in any Certificate or any other similar security from any
     person in any manner, (c) otherwise approach or negotiate with respect to
     any Certificate, any interest in any Certificate or any other similar
     security with any person in any manner, (d) make any general solicitation
     by means of general advertising or in any other manner or (e) take any
     other action, that (as to any of (a) through (e) above) would constitute a
     distribution of any Certificate under the Act, 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 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"), nor a Person acting,
     directly or indirectly, on behalf of any such plan, and understands that
     registration of transfer of any Certificate to any such employee benefit
     plan, or to any person acting on behalf of such plan, will not be made
     unless such employee benefit plan delivers an opinion of its counsel,
     addressed and satisfactory to the Trustee, the Depositor and the Master
     Servicer, to the effect that the purchase and holding of a Certificate by
     or on behalf of such employee benefit plan would not result in the assets
     of the Trust Estate being deemed to be "plan assets" and subject to the
     fiduciary responsibility provisions of ERISA or the prohibited transaction
     provisions of the Code (or comparable provisions of any 




                                       2

 
     subsequent enactments), would not constitute or result in a prohibited
     transaction under Section 406 of ERISA or Section 4975 of the Code, and
     would not subject the Depositor, the Servicer or the Trustee 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 or any other liability. The Purchaser understands that under
     current law such an opinion cannot be rendered.

                              Very truly yours,

any other similar security with any person in any manner, (d) has made any
general solicitation by means of general advertising or in any other manner, or
(e) has taken any other action, that (as to any of (a) through (e) above) would
constitute a distribution of the Certificates under the Securities Act of 1933
(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 Seller will not act in any
manner set forth in the foregoing sentence with respect to any Certificate. The
Seller has not and will not sell or otherwise transfer any of the Certificates,

          The undersigned seller, as registered holder (the "Transferor"),
intends to transfer the Rule 144A Securities described above to the undersigned
buyer (the "Buyer").

          1. In connection with such transfer and in accordance with the
agreements pursuant to which the Rule 144A Securities were issued, the
Transferor hereby certifies the following facts: Neither the Transferor nor
anyone acting on its behalf has offered, transferred, pledged, sold or otherwise
disposed of the Rule 144A Securities, any interest in the Rule 144A Securities
or any other similar security to, or solicited any offer to buy or accept a
transfer, pledge or other disposition of the Rule 144A Securities, or otherwise
approached or negotiated with respect to the Rule 144A Securities, any interest
in the Rule 144A Securities or any other similar security with, any person in
any manner, or made any general solicitation by means of general advertising or
in any other manner, or taken any other action, which would constitute a
distribution of the Rule 144A Securities under the Securities Act of 1933, as
amended (the "1933 Act"), or which would render the disposition of the Rule 144A
Securities a violation of Section 5 of the 1933 Act or require registration
pursuant thereto, and that the Transferor has not offered the Rule 144A
Securities to any person other than the Buyer or another "qualified
institutional buyer" as defined in Rule 144A under the 1933 Act.

          2. The Buyer warrants and represents to, and covenants with, the
Transferor, the Trustee and the Servicer pursuant to Section 5.02 of the Pooling
and Servicing Agreement as follows:

               a. The Buyer understands that the Rule 144A Securities have not

               b. The Buyer considers itself a substantial, sophisticated
     institutional investor having such knowledge and experience in financial
     and business matters that it is capable of evaluating the merits and risks
     of investment in the Rule 144A Securities.

     the Rule 144A Securities that it has requested from the Transferor, the
     Trustee or the Servicer.

               d. Neither the Buyer nor anyone acting on its behalf has offered,
     transferred, pledged, sold or otherwise disposed of the Rule 144A
     Securities, any interest in the Rule 144A Securities or any other similar
     security to, or solicited any offer to buy or accept a transfer, pledge or
     other disposition of the Rule 144A Securities, any interest in the Rule
     144A Securities or any other similar security from, or otherwise approached
     or negotiated with respect to the Rule 144A Securities, any 

 
     interest in the Rule 144A Securities or any other similar security with,
     any person in any manner, or made any general solicitation by means of
     general advertising or in any other manner, or taken any other action, that
     would constitute a distribution of the Rule 144A Securities under the 1933
     Act or that would render the disposition of the Rule 144A Securities a
     violation of Section 5 of the 1933 Act or require registration pursuant
     thereto, nor will it act, nor has it authorized or will it authorize any
     person to act, in such manner with respect to the Rule 144A Securities.

               e. The Buyer is a "qualified institutional buyer" as that term is
     defined in Rule 144A under the 1933 Act. The Buyer is aware that the sale

     for the account of a qualified institutional buyer to whom notice is given
     that the resale, pledge or transfer is being made in reliance on Rule 144A,
     or (ii) pursuant to another exemption from registration under the 1933 Act.

          3. The Buyer warrants and represents to, and covenants with, the
Transferor, the Servicer and the Depositor that either (1) the Buyer is not an
employee benefit plan within the meaning of Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") ("Plan"), or a plan
within the meaning of Section 4975(e)(1) of the Internal Revenue Code of 1986
(the "Code") (also a "Plan"), and the Buyer is not directly or indirectly
purchasing the Rule 144A Securities on behalf of, as investment manager of, as
named fiduciary of, as trustee of, or with assets of a Plan, or (2) the Buyer's
purchase of the Rule 144A Securities will not result in a prohibited transaction
under Section 406 of ERISA or Section 4975 of the Code.

the different parties hereto on separate counterparts, each of which, when so
