     Pooling and Servicing Agreement dated as of April 1, 1998, among Bear
Stearns Mortgage Securities Inc., a Delaware corporation, as the seller (the
"Seller"), and Norwest Bank Minnesota, National Association, a national banking
association, not in its individual capacity but solely as trustee (the
"Trustee").


                              PRELIMINARY STATEMENT

     On or prior to the Closing Date, the Seller has acquired the Mortgage Loans
from Bear Stearns Mortgage Capital Corporation ("BSMCC"). On the Closing Date,
the Seller will sell the Mortgage Loans and certain other property to the Trust
Fund and receive in consideration therefor Certificates evidencing the entire
beneficial ownership interest in the Trust Fund.

     The Trustee on behalf of the Trust shall make an election for the assets
constituting REMIC III to be treated for federal income tax purposes as a REMIC.
On the Startup Day, all the Classes of REMIC III Regular Certificates will be
designated "regular interests" in such REMIC and the Class R-3 Certificate will
be designated the "residual interests" in such REMIC.

     The Trustee on behalf of the Trust shall make an election for the assets
constituting REMIC II to be treated for federal income tax purposes as a REMIC.
On the Startup Day, all the Classes of REMIC II Regular Certificates will be
designated "regular interests" in such REMIC and the Class R-2 Certificates will
be designated the "residual interests" in such REMIC.

     The Trustee on behalf of the Trust shall make an election for the assets
constituting REMIC I to be treated for federal income tax purposes as a REMIC.
On the Startup Day, all the Classes of Certificates except for the Residual
Certificates will be designated "regular interests" in such REMIC and the Class
R-1 Certificates will be designated the "residual interests" in such REMIC.

     The Mortgage Loans will have an Outstanding Principal Balance as of the
Cut-off Date, after deducting all Scheduled Principal due on or before the
Cut-off Date, of $139,948,200. The initial principal amount of the Certificates
will not exceed such Outstanding Principal Balance.

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

                                    ARTICLE I

                                   Definitions

     Whenever used in this Agreement, the following words and phrases, unless
otherwise expressly provided or unless the context otherwise requires, shall
have the meanings specified in this Article.

     ACCOUNT: The Certificate Account (including each subaccount thereof) and
the Protected Accounts as the context may require.

     ACCRUED CERTIFICATE INTEREST: For any Certificate for any Distribution
Date, the interest accrued during the related Interest Accrual Period at the
applicable Pass-Through Rate on the Current Principal Amount of such Certificate
immediately prior to such Distribution Date, calculated on the basis of a
360-day year consisting of twelve 30-day months, less (i) in the case of a
Senior Certificate, such Certificate's share of any Net Interest Shortfall and
the interest portion of any Excess Losses and, after the applicable Cross-Over
Date, the interest portion of any Realized Losses and (ii) in the case of a
Subordinate Certificate, such Certificate's share of any Net Interest Shortfall
and the interest portion of any Realized Losses.

     ADJUSTMENT AMOUNT: For each anniversary of the Cut-off Date, the
"Adjustment Amount" shall be equal to the amount, if any, by which the
applicable Special Hazard Loss Amount (without giving effect to the deduction of
the Adjustment Amount for such anniversary) exceeds the lesser of (A) an amount
calculated by the Depositor and approved by each of S&P and DCR, which amount
shall not be less than $500,000, and (B) the greater of (x) 1.0% (or if greater
than 1.0%, the highest percentage of Mortgage Loans by principal balance secured
by Mortgaged Properties in any California zip code) of the outstanding principal
balance of all the Mortgage Loans on the Distribution Date immediately preceding
such anniversary and (y) twice the outstanding principal balance of the Mortgage
Loan which has the largest outstanding principal balance on the Distribution
Date immediately preceding such anniversary.

     AFFILIATE: As to any Person, any other Person controlling, controlled by or
under common control with such Person. "Control" means the power to direct the
management and policies of a Person, directly or indirectly, whether through
ownership of voting securities, by contract or otherwise. "Controlled" and
"Controlling" have meanings correlative to the foregoing. The Trustee may
conclusively presume that a Person is not an Affiliate of another Person unless
a Responsible Officer of the Trustee has actual knowledge to the contrary.

     AGREEMENT: This Pooling and Servicing Agreement and all amendments hereof
and supplements hereto.

     ALLOCABLE SHARE: With respect to each Class of Subordinate Certificates:

          (a) as to any Distribution Date and amounts distributable pursuant to
     clauses (i) and (iii) of the applicable Subordinate Optimal Principal
     Amount, the fraction, expressed as a percentage, the numerator of which is
     the Current Principal Amount of such Class and the denominator of which is
     the aggregate Current Principal Amount of all Classes of the Subordinate
     Certificates; and

          (b) as to any Distribution Date and amounts distributable pursuant to
     clauses (ii), (iv) and (v) of the applicable Subordinate Optimal Principal

including all interest and principal due with respect to the Mortgage Loans
after the Cut-off Date, but excluding any payments of principal and interest due
on or prior to the Cut-off Date; (ii) such assets as shall from time to time be
credited or are required by the terms of this Agreement to be credited to the
Certificate Account, (iii) such assets relating to the Mortgage Loans as from
time to time may be held by a Servicer in Protected Accounts for the benefit of
the holder of the Mortgage Loans, (iv) any REO Property, (v) the Required
Insurance Policies and any amounts paid or payable by the insurer under any
Insurance Policy (to the extent the mortgagee has a claim thereto), (vi) the
Mortgage Loan Purchase Agreement to the extent provided in Subsection 2.03(a),
and (vii) any proceeds of the foregoing. Although it is the intent of the
parties to this Agreement that the conveyance of the Seller's right, title and
interest in and to the Mortgage Loans and other assets in the Trust Fund
pursuant to this Agreement shall constitute a purchase and sale and not a loan,
in the event that such conveyance is deemed to be a loan, it is the intent of
the parties to this Agreement that the Seller shall be deemed to have granted to
the Trustee a first priority perfected security interest in all of the Seller's
right, title and interest in, to and under the Mortgage Loans and other assets
in the Trust Fund, and that this Agreement shall constitute a security agreement
under applicable law.

     (b) In connection with the above transfer and assignment, the Seller hereby
deposits with the Trustee, with respect to (A) each Mortgage Loan, other than
Cooperative Loans (i) the original Mortgage Note, endorsed without recourse to
the order of the Trustee and showing an unbroken chain of endorsements from the
original payee thereof to the Person endorsing it to the Trustee, (ii) the
original Security Instrument, which shall have been recorded, with evidence of
such recording indicated thereon, (iii) a certified copy of the assignment
(which may be in the form of a blanket assignment if permitted in the
jurisdiction in which the Mortgaged Property is located) to the Trustee of the
Security Instrument, with evidence of recording with respect to each Mortgage
Loan in the name of the Trustee thereon (or if (x) below applies, shall be in
recordable form), (iv) all intervening assignments of the Security Instrument,
if applicable and only to the extent available to the Seller with evidence of
recording thereon, (v) the original or a copy of the policy or certificate of
primary mortgage guaranty insurance, to the extent available, if any, (vi) the
original policy of title insurance or mortgagee's certificate of title insurance
or commitment or binder for title insurance and (vii) originals of all
modification agreements, if applicable and available and (B) each Cooperative
Loan (i) the original Mortgage Note, endorsed, without recourse to the order of
the Trustee, and showing, to the extent available, an unbroken chain of title
from the originator to the Trustee or, in the case of a Mortgage Loan that is
subject to the terms of a consolidation and modification agreement, an
assignment of such agreement to the Trustee; (ii) the original duly executed
assignment of security agreement to the Trustee; (iii) the original Mortgage;
(iv) the acknowledgment copy of the original executed Form UCC-1 (or certified
copy thereof) with respect to the security agreement, and any required
continuation statements, with evidence of filing indicated thereon; (v) the
acknowledgment copy of the original executed Form UCC-3 with respect to the
security agreement, indicating the Trustee as the assignee of the secured party,
with evidence of filing indicated thereon; (vi) the stock certificate
representing the stock allocated to the cooperative unit, with a stock power in
blank attached; (vii) the original collateral assignment of the lease by
Mortgagor to the originator and the assignment of the collateral assignment of
the lease to the Trustee (which may be in blanket form), accompanied by the
original lease; (viii) a copy of the recognition agreement; (ix) if applicable
and to the extent available, the original intervening assignments, including
warehousing assignments, if any, showing, to the extent available, an unbroken
chain of the related Mortgage Loan to the Trustee, together with a copy of the
related Form UCC-3 with evidence of filing thereon; (x) the originals of each
assumption, modification or substitution agreement, if any, relating to the
Mortgage Loan; and (xi) the certificate of primary mortgage insurance, if
applicable.

PROVIDED, HOWEVER, that in lieu of the foregoing, the Seller may deliver the
following documents, under the circumstances set forth below: (x) in lieu of the
original Security Instrument, assignments to the Trustee or intervening
assignments thereof which have been delivered, are being delivered or will, upon
receipt of recording information relating to the Security Instrument required to
be included thereon, be delivered to recording offices for recording and have
not been returned to the Seller in time to permit their delivery as specified
above, the Seller may deliver a true copy thereof with a certification by BSMCC
or the applicable Servicer, on the face of such copy, substantially as follows:
"Certified to be a true and correct copy of the original, which has been
transmitted for recording"; (y) in lieu of the Security Instrument, assignment
to the Trustee or intervening assignments thereof, if the applicable
jurisdiction retains the originals of such documents (as evidenced by a
certification from BSMCC or the applicable Servicer, to such effect) the Seller
may deliver photocopies of such documents containing an original certification
by the judicial or other governmental authority of the jurisdiction where such
documents were recorded; and (z) in lieu of the Mortgage Notes relating to any
Mortgage Loans, as identified in the list delivered by the Seller to the Trustee
on the Closing Date and set forth in Exhibit J hereto, the Seller may deliver a
lost note affidavit and, if available, a copy of the original Mortgage Note; and
PROVIDED, FURTHER, HOWEVER, that in the case of Mortgage Loans which have been
prepaid in full after the Cut-off Date and prior to the Closing Date, the
Seller, in lieu of delivering the above documents, may deliver to the Trustee a
certification to such effect and shall deposit all amounts paid in respect of
such Mortgage Loans in the Certificate Account on the Closing Date. The Seller
shall deliver such original documents (including any original documents as to
which certified copies had previously been delivered) to the Trustee promptly
after they are received. The Seller shall cause, at its expense, the assignment
of the Security Instrument to the Trustee to be recorded not later than 180 days
after the Closing Date. With respect to the Cooperative Loans, the Seller will,
promptly after the Closing Date, cause the related financing statements (if not
yet filed) and an assignment thereof from the Seller to the Trustee to be filed
in the appropriate offices.

     Section 2.02. ACCEPTANCE OF MORTGAGE LOANS BY TRUSTEE. (a) The Trustee
acknowledges receipt of, subject to further review and the exceptions which may
be noted pursuant to the procedures described below, and declares that it holds
the documents (or certified copies thereof) delivered to it pursuant to Section
2.01 and declares that it will continue to hold those documents and any
amendments, replacements or supplements thereto and all other assets of the
Trust Fund delivered to it as Trustee in trust for the use and benefit of all
present and future Holders of the Certificates. No later than 45 days after the
Closing Date (or, with respect to any Substitute Mortgage Loan, within five
Business Days after the receipt by the Trustee thereof), the Trustee agrees, for
the benefit of the Certificateholders, to review each Mortgage File delivered to
it and to execute and deliver, or cause to be executed and delivered, to the
Seller an Initial Certification substantially in the form annexed hereto as
Exhibit G. In conducting such review, the Trustee will ascertain whether all
required documents have been executed and received and whether those documents
relate, determined on the basis of the Mortgagor name, original principal
balance and loan number, to the Mortgage Loans it has received, as identified in
Exhibit B to this Agreement, as supplemented (PROVIDED, HOWEVER, that with
respect to those documents described in subclauses (b)(iv), (b)(v) and (b)(vi)
of Section 2.01, the Trustee's obligations shall extend only to documents
actually delivered pursuant to such subsections). In performing any such review,
the Trustee may conclusively rely on the purported due execution and genuineness
of any such document and on the purported genuineness of any signature thereon.
If the Trustee finds any document constituting part of the Mortgage File not to
have been executed or received, or to be unrelated to the Mortgage Loans
identified in Exhibit B or to appear to be defective on its face, the Trustee
shall promptly notify BSMCC and Dime. BSMCC or Dime shall correct or cure any
such defect within 90 days from the date of notice from the Trustee of the
defect and if BSMCC or Dime fails to correct or cure the defect within such
period, and such defect materially and adversely affects the interests of the
Certificateholders in the related Mortgage Loan, BSMCC or Dime will, subject to
Section 2.04, within 120 days from the Trustee's notification purchase such
Mortgage Loan at the Repurchase Price; PROVIDED, HOWEVER, that if such defect
relates solely to the inability of BSMCC or Dime to deliver the original
Security Instrument or intervening assignments thereof, or a certified copy
because the originals of such documents, or a certified copy have not been
returned by the applicable jurisdiction, BSMCC or Dime shall not be required to
purchase such Mortgage Loan if BSMCC or Dime delivers such original documents or
certified copy promptly upon receipt, but in no event later than 360 days after
the Closing Date. The foregoing repurchase obligation shall not apply in the
event that BSMCC or Dime cannot deliver such original or copy of any document
submitted for recording to the appropriate recording office in the applicable
jurisdiction because such document has not been returned by such office;
provided that BSMCC or Dime shall instead deliver a recording receipt of such
recording office or, if such receipt is not available, a certificate confirming
that such documents have been accepted for recording, and delivery to the
Trustee shall be effected by BSMCC or Dime within thirty days of its receipt of
the original recorded document.

     (b) No later than 180 days after the Closing Date, the Trustee will review,
for the benefit of the Certificateholders, the Mortgage Files delivered to it
and will execute and deliver or cause to be executed and delivered to the Seller
a Final Certification substantially in the form annexed hereto as Exhibit H. In
conducting such review, the Trustee will ascertain whether an original of each
document required to be recorded has been returned from the recording office
with evidence of recording thereon or a certified copy has been obtained from
the recording office. If the Trustee finds any document constituting part of the
Mortgage File has not been received, or to be unrelated, determined on the basis
of the Mortgagor name, original principal balance and loan number, to the
Mortgage Loans identified in Exhibit B or to appear defective on its face, the
Trustee shall promptly notify BSMCC (PROVIDED, HOWEVER, that with respect to
those documents described in subsection (b)(iv), (b)(v) and (b)(vi) of Section
2.01, the Trustee's obligations shall extend only to the documents actually
delivered pursuant to such subsections). BSMCC or Dime shall correct or cure any
such defect or shall deliver to the Trustee an Opinion of Counsel to the effect
that such defect does not materially or adversely affect the interests of
Certificateholders in such Mortgage Loan within 90 days from the date of notice
from the Trustee of the defect and if BSMCC or Dime is unable to cure such
defect within such period, and if such defect materially and adversely affects
the interests of the Certificateholders in the related Mortgage Loan, BSMCC or
Dime shall, subject to Section 2.04, within 120 days from the Trustee's
notification purchase such Mortgage Loan at the Repurchase Price; PROVIDED,
HOWEVER, that if such defect relates solely to the inability of BSMCC or Dime to
deliver the original Security Instrument or intervening assignments thereof, or
a certified copy, because the originals of such documents, or a certified copy,
have not been returned by the applicable jurisdiction, BSMCC or Dime shall not
be required to purchase such Mortgage Loan, if BSMCC or Dime delivers such
original documents or certified copy promptly upon receipt, but in no event
later than 360 days after the Closing Date.

     (c) In the event that a Mortgage Loan is purchased by BSMCC or Dime in
accordance with Subsections 2.02(a) or (b) above, BSMCC or Dime shall provide
the Repurchase Price to the Trustee for deposit in the Certificate Account and
shall provide to the Trustee written notification detailing the components of
the Repurchase Price. Upon deposit of the Repurchase Price in the Certificate
Account, the Trustee shall release to BSMCC or Dime the related Mortgage File
and shall execute and deliver all instruments of transfer or assignment, without
recourse, furnished to it by BSMCC or Dime as are necessary to vest in BSMCC or
Dime title to and rights under the Mortgage Loan. Such purchase shall be deemed
to have occurred on the date on which the Repurchase Price in available funds is
received by the Trustee. The Trustee shall amend the Mortgage Loan Schedule,
which was previously delivered to it by Seller in a form agreed to between the
Seller and the Trustee, to reflect such repurchase and shall promptly notify the
Rating Agencies of such amendment. The obligation of BSMCC or Dime to repurchase
any Mortgage Loan as to which such a defect in a constituent document exists
shall be the sole remedy respecting such defect available to the
Certificateholders or to the Trustee on their behalf. If Dime is obligated to
pay less than the Repurchase Price pursuant to the Dime Sale Agreement, BSMCC
shall be obligated to pay the difference between the Dime payment and the
Repurchase Price.

     Section 2.03. ASSIGNMENT OF INTEREST IN THE MORTGAGE LOAN PURCHASE
AGREEMENT. (a) The Seller hereby assigns to the Trustee all of its right, title
and interest in the Mortgage Loan Purchase Agreement, including but not limited
to Seller's rights and obligations pursuant to the Servicing Agreements and the
Dime Sale Agreement, provided that the Seller retains a joint and several right
in the event of breach of the representations, warranties and covenants of a
Servicer or Dime under any of the Servicing Agreements or the Dime Sale
Agreement to enforce the provisions thereof and to seek all or any available
remedies; and provided further that this shall not be deemed an agreement or
requirement on the part of the Seller to pursue any such remedies; provided,
further, that the obligations of BSMCC or Dime to substitute or repurchase a
Mortgage Loan shall be the Trustee's and the Certificateholders' sole remedy for
any breach thereof. At the request of the Trustee, the Seller shall take such
actions as may be necessary to enforce the above right, title and interest on
behalf of the Trustee and the Certificateholders or shall execute such further
documents as the Trustee may reasonably require in order to enable the Trustee
to carry out such enforcement.

     (b) If the Seller or the Trustee discovers a breach of any of the
representations and warranties set forth in Exhibit C or Section 7 of the
Mortgage Loan Purchase Agreement and such breach existed on the date the
representation and warranty was made, which breach materially and adversely
affects the value of the interests of Certificateholders or the Trustee in the
related Mortgage Loan, the party discovering the breach shall give prompt
written notice of the breach to the other parties. BSMCC within 90 days of its
discovery or receipt of notice that such breach has occurred (whichever occurs
earlier), shall cure the breach in all material respects or, subject to Section
2.04, shall purchase the Mortgage Loan or any property acquired with respect
thereto from the Trustee; PROVIDED, HOWEVER, that if there is a breach of any
representation set forth in Exhibit C and the Mortgage Loan or the related
property acquired with respect thereto has been sold, then BSMCC shall pay, in
lieu of the Repurchase Price, any excess of the Repurchase Price over the Net
Liquidation Proceeds received upon such sale. (If the Net Liquidation Proceeds
exceed the Repurchase Price, any excess shall be paid to BSMCC to the extent not
required by law to be paid to the borrower.) Any such purchase by BSMCC shall be
made by providing an amount equal to the Repurchase Price to the Trustee for
deposit in the Certificate Account and the Trustee, upon deposit of the
Repurchase Price in the Certificate Account and of written notification
detailing the components of such Repurchase Price, shall release to BSMCC the
related Mortgage File and shall execute and deliver all instruments of transfer
or assignment furnished to it by BSMCC, without recourse, as are necessary to
vest in BSMCC title to and rights under the Mortgage Loan or any property
acquired with respect thereto. Such purchase shall be deemed to have occurred on
the date on which the Repurchase Price in available funds is received by the
Trustee. The Trustee shall amend the Mortgage Loan Schedule to reflect such
repurchase and shall promptly notify the Servicer and the Rating Agencies of
such amendment. Enforcement of the obligation of BSMCC, to purchase (or
substitute a Substitute Mortgage Loan for) any Mortgage Loan or any property
acquired with respect thereto (or pay the Repurchase Price as set forth in the
above proviso) as to which a breach has occurred and is continuing shall
constitute the sole remedy respecting such breach available to the
Certificateholders or the Trustee on their behalf. If Dime is obligated to pay
less than the Repurchase Price pursuant to the Dime Sale Agreement, BSMCC shall
be obligated to pay the difference between the Dime payment and the Repurchase
Price.

     Section 2.04. SUBSTITUTION OF MORTGAGE LOANS. Notwithstanding anything to
the contrary in this Agreement, in lieu of purchasing a Mortgage Loan pursuant
to Sections 2.02 or 2.03, BSMCC or Dime may, no later than the date by which
such purchase by BSMCC or Dime would otherwise be required, tender to the
Trustee a Substitute Mortgage Loan accompanied by a certificate of an authorized
officer of BSMCC or Dime that such Substitute Mortgage Loan conforms to the
requirements set forth in the definition of "Substitute Mortgage Loan";
PROVIDED, HOWEVER, that substitution pursuant to this Section 2.04 in lieu of
purchase shall not be permitted after the termination of the two-year period
beginning on the Startup Day. The Trustee shall examine the Mortgage File for
any Substitute Mortgage Loan in the manner set forth in Section 2.02(a) and
shall notify BSMCC or Dime in writing, within five Business Days after receipt,
whether or not the documents relating to the Substitute Mortgage Loan satisfy
the requirements of the third sentence of Subsection 2.02(a). Within two
Business Days after such notification, BSMCC or Dime shall provide to the
Trustee for deposit in the Certificate Account the amount, if any, by which the
Outstanding Principal Balance as of the next preceding Due Date of the Mortgage
Loan for which substitution is being made, after giving effect to Scheduled
Principal due on such date, exceeds the Outstanding Principal Balance as of such
date of the Substitute Mortgage Loan, after giving effect to Scheduled Principal
due on such date, which amount shall be treated for the purposes of this
Agreement as if it were the payment by BSMCC or Dime of the Repurchase Price for
the purchase of a Mortgage Loan by BSMCC or Dime. After such notification to
BSMCC or Dime and, if any such excess exists, upon receipt of such deposit, the
Trustee shall accept such Substitute Mortgage Loan which shall thereafter be
deemed to be a Mortgage Loan hereunder. In the event of such a substitution,
accrued interest on the Substitute Mortgage Loan for the month in which the
substitution occurs and any Principal Prepayments made thereon during such month
shall be the property of the Trust Fund and accrued interest for such month on
the Mortgage Loan for which the substitution is made and any Principal
Prepayments made thereon during such month shall be the property of BSMCC or
Dime. The Scheduled Principal on a Substitute Mortgage Loan due on the Due Date
in the month of substitution shall be the property of BSMCC or Dime and the
Scheduled Principal on the Mortgage Loan for which the substitution is made due
on such Due Date shall be the property of the Trust Fund. Upon acceptance of the
Substitute Mortgage Loan, the Trustee shall release to BSMCC or Dime the related
Mortgage File related to any Mortgage Loan released pursuant to this Section
2.04 and shall execute and deliver all instruments of transfer or assignment,
without recourse, in form as provided to it as are necessary to vest in BSMCC or
Dime title to and rights under any Mortgage Loan released pursuant to this
Section 2.04. BSMCC or Dime shall deliver the documents related to the
Substitute Mortgage Loan in accordance with the provisions of Subsections
2.01(b) and 2.02(b), with the date of acceptance of the Substitute Mortgage Loan
deemed to be the Closing Date for purposes of the time periods set forth in
those Subsections. The representations and warranties set forth in the
applicable Servicing Agreement and Exhibit C shall be deemed to have been made
by BSMCC or Dime with respect to each Substitute Mortgage Loan as of the date of
acceptance of such Mortgage Loan by the Trustee. The Trustee shall amend the
Mortgage Loan Schedule to reflect such substitution and shall provide a copy of
such amended Mortgage Loan Schedule to the Servicer and the Rating Agencies.

     Section 2.05. ISSUANCE OF CERTIFICATES. The Trustee acknowledges the
assignment to it of the Mortgage Loans and the other assets comprising the Trust
Fund and, concurrently therewith, has signed, and countersigned and delivered to
the Seller, in exchange therefor, Certificates in such authorized denominations
representing such Fractional Undivided Interests as the Seller has requested.
The Trustee agrees that it will hold the Mortgage Loans and such other assets as
may from time to time be delivered to it segregated on the books of the Trustee
in trust for the benefit of the Certificateholders.

     Section 2.06. REPRESENTATIONS AND WARRANTIES CONCERNING THE SELLER. The
Seller hereby represents and warrants to the Trustee as follows:

          (i) the Seller (a) is a corporation duly organized, validly existing
     and in good standing under the laws of the State of Delaware and (b) is

     each jurisdiction where such qualification is necessary, except where the
     failure so to qualify would not reasonably be expected to have a material
     adverse effect on the Seller's business as presently conducted or on the
     Purchaser's ability to enter into this Agreement and to consummate the
     transactions contemplated hereby;

          (ii) the Seller has full corporate power to own its property, to carry
     on its business as presently conducted and to enter into and perform its
     obligations under this Agreement;

          (iii) the execution and delivery by the Seller of this Agreement have
     been duly authorized by all necessary corporate action on the part of the
     Seller; and neither the execution and delivery of this Agreement, nor the
     consummation of the transactions herein contemplated, nor compliance with
     the provisions hereof, will conflict with or result in a breach of, or
     constitute a default under, any of the provisions of any law, governmental
     rule, regulation, judgment, decree or order binding on the Seller or its
     properties or the articles of incorporation or by-laws of the Seller,
     except those conflicts, breaches or defaults which would not reasonably be
     expected to have a material adverse effect on the Seller's ability to enter
     into this Agreement and to consummate the transactions contemplated hereby;

          (iv) the execution, delivery and performance by the Seller of this
     Agreement and the consummation of the transactions contemplated hereby do
     not require the consent or approval of, the giving of notice to, the
     registration with, or the taking of any other action in respect of, any
     state, federal or other governmental authority or agency, except those
     consents, approvals, notices, registrations or other actions as have
     already been obtained, given or made;

          (v) this Agreement has been duly executed and delivered by the Seller
     and, assuming due authorization, execution and delivery by the other
     parties hereto, constitutes a valid and binding obligation of the Seller
     enforceable against it in accordance with its terms (subject to applicable
     bankruptcy and insolvency laws and other similar laws affecting the
     enforcement of the rights of creditors generally);

          (vi) there are no actions, suits or proceedings pending or, to the
     knowledge of the Seller, threatened against the Seller, before or by any
     court, administrative agency, arbitrator or governmental body (i) with
     respect to any of the transactions contemplated by this Agreement or (ii)
     with respect to any other matter which in the judgment of the Seller will
     be determined adversely to the Seller and will if determined adversely to
     the Seller materially and adversely affect the Seller's ability to enter
     into this Agreement or perform its obligations under this Agreement; and
     the Seller is not in default with respect to any order of any court,
     administrative agency, arbitrator or governmental body so as to materially
     and adversely affect the transactions contemplated by this Agreement; and

          (vii) immediately prior to the transfer and assignment to the Trustee,
     each Mortgage Note and each Mortgage were not subject to an assignment or
     pledge, and the Seller had good and marketable title to and was the sole
     owner thereof and had full right to transfer and sell such Mortgage Loan to
     the Trustee free and clear of any encumbrance, equity, lien, pledge,
     charge, claim or security interest.

     Section 3.01. SERVICER. The BA Loans shall be serviced pursuant to the BA
Agreement and the Chase Loans shall be serviced pursuant to the Chase Agreement.
The Trustee shall furnish each Servicer with any powers of attorney and other
documents in form as provided to it necessary or appropriate to enable each
Servicer to service and administer the related Mortgage Loans and REO Property.

     The Trustee shall provide access to the records and documentation in
possession of the Trustee regarding the related Mortgage Loans and REO Property
and the servicing thereof to the Certificateholders, the FDIC, and the
supervisory agents and examiners of the FDIC, such access being afforded only
upon reasonable prior written request and during normal business hours at the
office of the Trustee; PROVIDED, HOWEVER, that, unless otherwise required by
law, the Trustee shall not be required to provide access to such records and
documentation if the provision thereof would violate the legal right to privacy
of any Mortgagor. The Trustee shall allow representatives of the above entities
to photocopy any of the records and documentation and shall provide equipment
for that purpose at a charge that covers the Trustee's actual costs.

     Upon receipt of a request by a Servicer, the Trustee shall release within
five Business Days the related Mortgage File to the Servicer and execute and
deliver to the Servicer, without recourse, a request for reconveyance, deed of
reconveyance or release or satisfaction of mortgage or such instrument releasing

of reconveyance shall be chargeable to the Certificate Account.

treatment of each such REMIC as a REMIC, and the Trustee shall comply with any
directions of the Seller or the Servicer to assure such continuing treatment. In
particular, the Trustee shall not (a) sell or permit the sale of all or any
portion of the Mortgage Loans or of any investment of deposits in an Account
unless such sale is as a result of a repurchase of the Mortgage Loans pursuant
to this Agreement or the Trustee has received a REMIC Opinion prepared at the
expense of the Trust Fund; and (b) other than with respect to a substitution
pursuant to Section 2.04, accept any contribution to any REMIC after the Startup
Day without receipt of a REMIC Opinion.

                                    Accounts

     Section 4.01. CERTIFICATE ACCOUNT. (a) The Trustee shall establish and
maintain in the name of the Trustee, for the benefit of the Certificateholders,
the Certificate Account as a segregated non-interest bearing trust account or

          (i) Any amounts withdrawn from a Protected Account;

          (ii) Any Monthly Advance and any Compensating Interest Payments;

          (iii) Any Insurance Proceeds or Liquidation Proceeds received by or on
     behalf of the Trustee which were not deposited in a Protected Account;

          (iv) The Repurchase Price with respect to any Mortgage Loans purchased
     by BSMCC or Dime pursuant to Sections 2.02 or 2.03, any amounts which are
     to be treated pursuant to Section 2.04 as the payment of such a Repurchase
     Price and all proceeds of any Mortgage Loans or property acquired in
     connection with a purchase pursuant to any Servicing Agreement or the
     optional termination of the Trust;

          (v) Any amounts required to be deposited with respect to losses on

Certificateholders in accordance with the terms and provisions of this
Agreement.

     (c) The Certificate Account shall constitute a trust account of the Trust
Fund segregated on the books of the Trustee and held by the Trustee in trust in
its Corporate Trust Office, and the Certificate Account and the funds deposited
therein shall not be subject to, and shall be protected from, all claims, liens,
and encumbrances of any creditors or depositors of the Trustee or the Servicer
(whether made directly, or indirectly through a liquidator or receiver of the
Trustee or the Servicer). The amount at any time credited to the Certificate
Account shall be (i) fully insured by the FDIC to the maximum coverage provided
thereby or (ii) invested in the name of the Trustee, in such Permitted
Investments selected by the Trustee or deposited in demand deposits with such
depository institutions as selected by the Trustee, provided that time deposits
of such depository institutions would be a Permitted Investment. All Permitted
Investments shall mature or be subject to redemption or withdrawal on or before,
and shall be held until, the next succeeding Distribution Date if the obligor
for such Permitted Investment is the Trustee or, if such obligor is any other
Person, the Business Day preceding such Distribution Date. All investment
earnings on amounts on deposit in the Certificate Account from time to time
shall be for the account of the Trustee. The Trustee shall be permitted to
withdraw any and all investment earnings from the Certificate Account at any
time. If there is any loss on a Permitted Investment or demand deposit, the
Trustee shall deposit the amount of the loss in the Certificate Account. With
respect to the Certificate Account and the funds deposited therein, the Trustee
shall take such action as may be necessary to ensure that the Certificateholders
shall be entitled to the priorities afforded to such a trust account (in
addition to a claim against the estate of the Trustee) as provided by 12 U.S.C.
ss. 92a(e), if applicable, or any applicable comparable state statute applicable
to state chartered banking corporations.

     Section 4.02. PERMITTED WITHDRAWALS AND TRANSFERS FROM THE CERTIFICATE
ACCOUNT. (a) The Trustee will, from time to time on demand of any Servicer, make
or cause to be made such withdrawals or transfers from the Certificate Account
as the Servicer has designated for such transfer or withdrawal pursuant to its
Servicing Agreement. The Trustee may clear and terminate the Certificate Account
pursuant to Section 10.01 and remove amounts from time to time deposited in
error.

     (b) On each Distribution Date, the Trustee shall pay the amount
distributable to the Holders of the Certificates in accordance with Section 6.01
from the funds in the Certificate Account. The Trustee shall direct any
investments of the Certificate Account and may retain for its own account the
amount of investment earnings, net of losses, from the Certificate Account.

                                  Certificates


     Section 5.01. CERTIFICATES. (a) The Depository, the Seller and the Trustee
have entered into Depository Agreements dated as of April 30, 1998 (the
"Depository Agreement"). Except for the Residual Certificates, the Private
Certificates and the Individual Certificates and as provided in Subsection
5.01(b), the Certificates shall at all times remain registered in the name of
the Depository or its nominee and at all times: (i) registration of such
Certificates may not be transferred by the Trustee except to a successor to the
Depository; (ii) ownership and transfers of registration of such Certificates on
the books of the Depository shall be governed by applicable rules established by
the Depository; (iii) the Depository may collect its usual and customary fees,
charges and expenses from its Depository Participants; (iv) the Trustee shall
deal with the Depository as representative of such Certificate Owners of the
respective Class of Certificates for purposes of exercising the rights of
Certificateholders under this Agreement, and requests and directions for and
votes of such representative shall not be deemed to be inconsistent if they are
made with respect to different Certificate Owners; and (v) the Trustee may rely
and shall be fully protected in relying upon information furnished by the
Depository with respect to its Depository Participants.

     The Residual Certificates and the Private Certificates are initially
Physical Certificates. If at any time the Holders of all of the Certificates of
one or more such Classes request that the Trustee cause such Class to become
Global Certificates, the Trustee and the Seller will take such action as may be
reasonably required to cause the Depository to accept such Class or Classes for
trading.

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

     (b) If (i)(A) the Seller advises the Trustee in writing that the Depository
is no longer willing or able to properly discharge its responsibilities as
Depository and (B) the Trustee or the Seller is unable to locate a qualified
successor within 30 days or (ii) the Seller at its option advises the Trustee in
writing that it elects to terminate the book-entry system through the
Depository, the Trustee shall request that the Depository notify all Certificate
Owners of the occurrence of any such event and of the availability of
definitive, fully registered Certificates to Certificate Owners requesting the
same. Upon surrender to the Trustee of the Certificates by the Depository,
accompanied by registration instructions from the Depository for registration,
the Trustee shall issue the definitive Certificates. Neither the Seller nor the
Trustee shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.

     (c) REMIC II and III will be evidenced by (x) the REMIC II or III Regular
Certificate, respectively, which will be uncertificated and non-transferable and
is hereby designated as the "regular interest" in REMIC II or III, respectively,
and (y) the Class R-2 or Class R-3 Certificate, respectively, which is hereby
designated as the single "residual interest" in REMIC II or III, respectively.
Any amounts with respect to the BA Mortgage Loans and Chase Mortgage Loans
payable to the Certificates other than the Residual Certificates shall be
payable to the REMIC II or III Regular Certificates, respectively.

     (d) The Classes of the Certificates shall have the following designations,
initial principal amounts and Pass-Through Rates:

      DESIGNATION            INITIAL PRINCIPAL  AMOUNT    PASS-THROUGH RATE

          A-1                $14,325,000                     (1)
          A-2                $71,625,700                     (1)
          A-3                $42,382,750                     (1)
          A-4                 $9,865,250                     (1)
          B-1                   $699,700                     (1)
          B-2                   $349,900                     (1)
          B-3                   $279,900                     (1)
          B-4                   $140,000                     (1)
          B-5                   $139,900                     (1)
          B-6                   $140,000                     (1)
          R-1                        $50                     (1)

          R-3                        $25                     (1)

- -----------
(1) The Certificates will bear interest at a variable rate equal to the weighted
average of the Net Rates of the Mortgage Loans.

     (e) With respect to each Distribution Date, each Class of Certificates
shall accrue interest during the related Interest Accrual Period. With respect
to each Distribution Date and each such Class of Certificates, interest shall be
calculated, on the basis of a 360-day year comprised of twelve 30-day months,
based upon the respective Pass-Through Rate set forth, or determined as
provided, above and the Current Principal Amount of such Class applicable to
such Distribution Date.

     (f) The Certificates shall be substantially in the forms set forth in
Exhibit A-1 and A- 2. On original issuance, the Trustee shall sign, countersign
and shall deliver them at the direction of the Seller. Pending the preparation
of definitive Certificates of any Class, the Trustee may sign and countersign
temporary Certificates that are printed, lithographed or typewritten, in
authorized denominations for Certificates of such Class, substantially of the
tenor of the definitive Certificates in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers or authorized signatories executing such Certificates may
determine, as evidenced by their execution of such Certificates. If temporary
Certificates are issued, the Seller will cause definitive Certificates to be
prepared without unreasonable delay. After the preparation of definitive
Certificates, the temporary Certificates shall be exchangeable for definitive
Certificates upon surrender of the temporary Certificates at the office of the
Trustee, without charge to the Holder. Upon surrender for cancellation of any
one or more temporary Certificates, the Trustee shall sign and countersign and
deliver in exchange therefor a like aggregate principal amount, in authorized
denominations for such Class, of definitive Certificates of the same Class.
Until so exchanged, such temporary Certificates shall in all respects be
entitled to the same benefits as definitive Certificates.

     (g) Each Class of Book-Entry Certificates will be registered as a single
Certificate of such Class held by a nominee of the Depository or the DTC
Custodian, and beneficial interests will be held by investors through the
book-entry facilities of the Depository in minimum denominations of (i) in the
case of the Senior Certificates (other than the Residual Certificates), $1,000
and in each case increments of $1.00 in excess thereof, and (ii) in the case of
the Offered Subordinate Certificates, $25,000 and increments of $1.00 in excess
thereof, except that one Certificate of each such Class may be issued in a
different amount so that the sum of the denominations of all outstanding
Certificates of such Class shall equal the Current Principal Amount of such
Class on the Closing Date. On the Closing Date, the Trustee shall execute and
countersign Physical Certificates all in an aggregate principal amount that
shall equal the Current Principal Amount of such Class on the Closing Date. The
Class B-4, Class B-5, Class B-6 Certificates will be issued in certificated
fully-registered form in minimum denominations of $50,000 and increments of
$1.00 in excess thereof, except that one Certificate of each such Class may be
issued in a different amount so that the sum of the denominations of all
outstanding Certificates of such Class shall equal the Current Principal Amount
of such Class on the Closing Date. The Class R-1, Class R-2 and Class R-3
Certificates shall be issued in certificated fully- registered form in the
denomination of $50, $25 and $25, respectively. Each Class of Global
Certificates, if any, shall be issued in fully registered form in minimum dollar
denominations of $50,000 and integral multiples of $1.00 in excess thereof,
except that one Certificate of each Class may be in a different denomination so
that the sum of the denominations of all outstanding Certificates of such Class
shall equal the Current Principal Amount of such Class on the Closing Date. On
the Closing Date, the Trustee shall execute and countersign (i) in the case of
each Class of Offered Certificates, the Certificate in the entire Current
Principal Amount of the respective Class and (ii) in the case of each Class of
Private Certificates, Individual Certificates all in an aggregate principal
amount that shall equal the Current Principal Amount of each such respective
Class on the Closing Date. The Certificates referred to in clause (i) and if at
any time there are to be Global Certificates, the Global Certificates shall be
delivered by the Seller to the Depository or pursuant to the Depository's
instructions, shall be delivered by the Seller on behalf of the Depository to
and deposited with the DTC Custodian. The Trustee shall sign the Certificates by
facsimile or manual signature and countersign them by manual signature on behalf
of the Trustee by one or more authorized signatories, each of whom shall be
Responsible Officers of the Trustee or its agent. A Certificate bearing the
manual and facsimile signatures of individuals who were the authorized
signatories of the Trustee or its agent at the time of issuance shall bind the
Trustee, notwithstanding that such individuals or any of them have ceased to
hold such positions prior to the delivery of such Certificate.

     (h) No Certificate shall be entitled to any benefit under this Agreement,
or be valid for any purpose, unless there appears on such Certificate the
manually executed countersignature of the Trustee or its agent, and such
countersignature upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly executed and delivered hereunder.
All Certificates issued on the Closing Date shall be dated the Closing Date. All
Certificates issued thereafter shall be dated the date of their
countersignature.

     (i) The Closing Date is hereby designated as the "startup" day of each
REMIC within the meaning of Section 860G(a)(9) of the Code.

     (j) For federal income tax purposes, each REMIC shall have a tax year that
is a calendar year and shall report income on an accrual basis.

     (k) The Trustee on behalf of the Trust shall cause each REMIC to elect to
be treated as a real estate mortgage investment conduit under Section 860D of
the Code. Any inconsistencies or ambiguities in this Agreement or in the
administration of any Trust established hereby shall be resolved in a manner
that preserves the validity of such elections.

     (l) The Assumed Final Distribution Date for distributions on the
Certificates is as follows: January 25, 2007 for Class A-3, March 25, 2008 for
Class A-1, and December 25, 2008 for the remaining Classes of Certificates. The
Assumed Final Distribution Date in the case of the Class A-3 and Class A-1
Certificates is the Distribution Date on which the Current Principal Amount of
Class A-3 and Class A-1 Certificates, respectively, is reduced to zero, assuming
a constant percentage of 0% SPA and the assumptions set forth under "Yield and
Prepayment Considerations-Decrement Tables" in the Prospectus Supplement. The
Assumed Final Distribution Date in the case of all Classes of Certificates other
than the Class A-1 and Class A-3 Certificates is the Distribution Date in the
month following the latest scheduled maturity of all the Mortgage Loans.

     Section 5.02. REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES. (a)
The Trustee shall maintain at its Corporate Trust Office a Certificate Register
in which, subject to such reasonable regulations as it may prescribe, the
Trustee shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided.

     (b) Subject to Subsection 5.01(a) and, in the case of any Global
Certificate or Physical Certificate upon the satisfaction of the conditions set
forth below, upon surrender for registration of transfer of any Certificate at
any office or agency of the Trustee maintained for such purpose, the Trustee
shall sign, countersign and shall deliver, in the name of the designated
transferee or transferees, a new Certificate of a like Class and aggregate
Fractional Undivided Interest, but bearing a different number.

     (c) By acceptance of an Individual Certificate, whether upon original
issuance or subsequent transfer, each holder of such a Certificate acknowledges
the restrictions on the transfer of such Certificate set forth in the Securities
Legend and agrees that it will transfer such a Certificate only as provided
herein. In addition to the provisions of Subsection 5.02(h), the following
restrictions shall apply with respect to the transfer and registration of
transfer of an Individual Certificate to a transferee that takes delivery in the
form of an Individual Certificate:

          (i) The Trustee shall register the transfer of an Individual
     Certificate if the requested transfer is being made to a transferee who has
     provided the Trustee with a Rule 144A Certificate or comparable evidence as
     to its QIB status.

          (ii) The Trustee shall register the transfer of any Individual
     Certificate if (x) the transferor has advised the Trustee in writing that
     the Certificate is being transferred to an Institutional Accredited
     Investor; and (y) prior to the transfer the transferee furnishes to the
     Trustee an Investment Letter (and the Trustee shall be fully protected in
     so doing), provided that, if based upon an Opinion of Counsel to the effect
     that the delivery of (x) and (y) above are not sufficient to confirm that
     the proposed transfer is being made pursuant to an exemption from, or in a
     transaction not subject to, the registration requirements of the Securities
     Act and other applicable laws, the Trustee shall as a condition of the
     registration of any such transfer require the transferor to furnish such
     other certifications, legal opinions or other information prior to
     registering the transfer of an Individual Certificate as shall be set forth
     in such Opinion of Counsel.

     (d) Subject to Subsection 5.02(h), so long as a Global Certificate of such
Class is outstanding and is held by or on behalf of the Depository, transfers of
beneficial interests in such Global Certificate, or transfers by holders of
Individual Certificates of such Class to transferees that take delivery in the
form of beneficial interests in the Global Certificate, may be made only in
accordance with this Subsection 5.02(d) and in accordance with the rules of the
Depository:

          (i) In the case of a beneficial interest in the Global Certificate
     being transferred to an Institutional Accredited Investor, such transferee
     shall be required to take delivery in the form of an Individual Certificate
     or Certificates and the Trustee shall register such transfer only upon
     compliance with the provisions of Subsection 5.02(c)(ii).

          (ii) In the case of a beneficial interest in a Class of Global
     Certificates being transferred to a transferee that takes delivery in the
     form of an Individual Certificate or Certificates of such Class, except as
     set forth in clause (i) above, the Trustee shall register such transfer
     only upon compliance with the provisions of Subsection 5.02(c)(i).

          (iii) In the case of an Individual Certificate of a Class being
     transferred to a transferee that takes delivery in the form of a beneficial
     interest in a Global Certificate of such Class, the Trustee shall register
     such transfer if the transferee has provided the Trustee with a Rule 144A
     Certificate or comparable evidence as to its QIB status.

          (iv) No restrictions shall apply with respect to the transfer or
     registration of transfer of a beneficial interest in the Global Certificate
     of a Class to a transferee that takes delivery in the form of a beneficial
     interest in the Global Certificate of such Class; provided that each such
     transferee shall be deemed to have made such representations and warranties
     contained in the Rule 144A Certificate as are sufficient to establish that
     it is a QIB.

     (e) Subject to Subsection 5.02(h), an exchange of a beneficial interest in
a Global Certificate of a Class for an Individual Certificate or Certificates of
such Class, an exchange of an Individual Certificate or Certificates of a Class
for a beneficial interest in the Global Certificate of such Class and an
exchange of an Individual Certificate or Certificates of a Class for another
Individual Certificate or Certificates of such Class (in each case, whether or
not such exchange is made in anticipation of subsequent transfer, and, in the
case of the Global Certificate of such Class, so long as such Certificate is
outstanding and is held by or on behalf of the Depository) may be made only in
accordance with this Subsection 5.02(e) and in accordance with the rules of the
Depository:

          (i) A holder of a beneficial interest in a Global Certificate of a
     Class may at any time exchange such beneficial interest for an Individual
     Certificate or Certificates of such Class.

          (ii) A holder of an Individual Certificate or Certificates of a Class
     may exchange such Certificate or Certificates for a beneficial interest in
     the Global Certificate of such Class if such holder furnishes to the
     Trustee a Rule 144A Certificate or comparable evidence as to its QIB
     status.

          (iii) A holder of an Individual Certificate of a Class may exchange
     such Certificate for an equal aggregate principal amount of Individual
     Certificates of such Class in different authorized denominations without
     any certification.

     (f) (i) Upon acceptance for exchange or transfer of an Individual
Certificate of a Class for a beneficial interest in a Global Certificate of such
Class as provided herein, the Trustee shall cancel such Individual Certificate
and shall (or shall request the Depository to) endorse on the schedule affixed
to the applicable Global Certificate (or on a continuation of such schedule
affixed to the Global Certificate and made a part thereof) or otherwise make in
its books and records an appropriate notation evidencing the date of such
exchange or transfer and an increase in the certificate balance of the Global
Certificate equal to the certificate balance of such Individual Certificate
exchanged or transferred therefor.

          (ii) Upon acceptance for exchange or transfer of a beneficial interest
     in a Global Certificate of a Class for an Individual Certificate of such
     Class as provided herein, the Trustee shall (or shall request the
     Depository to) endorse on the schedule affixed to such Global Certificate
     (or on a continuation of such schedule affixed to such Global Certificate
     and made a part thereof) or otherwise make in its books and records an
     appropriate notation evidencing the date of such exchange or transfer and a
     decrease in the certificate balance of such Global Certificate equal to the
     certificate balance of such Individual Certificate issued in exchange
     therefor or upon transfer thereof.

     (g) The Securities Legend shall be placed on any Individual Certificate
issued in exchange for or upon transfer of another Individual Certificate or of
a beneficial interest in a Global Certificate.

     (h) Subject to the restrictions on transfer and exchange set forth in this
Section 5.02, the holder of any Individual Certificate may transfer or exchange
the same in whole or in part (in an initial certificate balance equal to the
minimum authorized denomination or any integral multiple of $1.00 in excess
thereof) by surrendering such Certificate at the Corporate Trust Office, or at
the office of any transfer agent, together with an executed instrument of
assignment and transfer satisfactory in form and substance to the Trustee in the
case of transfer and a written request for exchange in the case of exchange. The
holder of a beneficial interest in a Global Certificate may, subject to the
rules and procedures of the Depository, cause the Depository (or its nominee) to
notify the Trustee in writing of a request for transfer or exchange of such
beneficial interest for an Individual Certificate or Certificates. Following a
proper request for transfer or exchange, the Trustee shall, within five Business
Days of such request made at such Corporate Trust Office, sign, countersign and
deliver at such Corporate Trust Office, to the transferee (in the case of
transfer) or holder (in the case of exchange) or send by first class mail at the
risk of the transferee (in the case of transfer) or holder (in the case of
exchange) to such address as the transferee or holder, as applicable, may
request, an Individual Certificate or Certificates, as the case may require, for
a like aggregate Fractional Undivided Interest and in such authorized
denomination or denominations as may be requested. The presentation for transfer
or exchange of any Individual Certificate shall not be valid unless made at the
Corporate Trust Office by the registered holder in person, or by a duly
authorized attorney-in-fact.

     (i) At the option of the Certificateholders, Certificates may be exchanged
for other Certificates of authorized denominations of a like Class and aggregate
Fractional Undivided Interest, upon surrender of the Certificates to be
exchanged at any such office or agency; PROVIDED, HOWEVER, that no Certificate
may be exchanged for new Certificates unless the original Fractional Undivided
Interest represented by each such new Certificate (i) is at least equal to the
minimum authorized denomination or (ii) is acceptable to the Seller as indicated
to the Trustee in writing. Whenever any Certificates are so surrendered for
exchange, the Trustee shall sign and countersign and the Trustee shall deliver
the Certificates which the Certificateholder making the exchange is entitled to
receive.

     (j) If the Trustee so requires, every Certificate presented or surrendered
for transfer or exchange shall be duly endorsed by, or be accompanied by a
written instrument of transfer, with a signature guarantee, in form satisfactory
to the Trustee, duly executed by the holder thereof or his or her attorney duly
authorized in writing.

     (k) 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.

     (l) The Trustee shall cancel all Certificates surrendered for transfer or
exchange but shall retain such Certificates in accordance with its standard
retention policy or for such further time as is required by the record retention
requirements of the Securities Exchange Act of 1934, as amended, and thereafter
may destroy such Certificates.

     (m) The following legend shall be placed on each Class of Subordinate
Certificates, whether upon original issuance or upon issuance of any other
Certificate of any such Class in exchange therefor or upon transfer thereof:

     THIS CERTIFICATE MAY NOT BE ACQUIRED DIRECTLY OR INDIRECTLY BY, OR ON
     BEHALF OF, AN EMPLOYEE BENEFIT PLAN OR OTHER RETIREMENT ARRANGEMENT WHICH
     IS SUBJECT TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF
     1974, AS AMENDED, AND/OR SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986,
     AS AMENDED, UNLESS THE PROPOSED TRANSFER AND/OR HOLDING OF A CERTIFICATE
     AND THE SERVICING, MANAGEMENT AND/OR OPERATION OF THE TRUST AND ITS ASSETS:
     (I) WILL NOT RESULT IN ANY PROHIBITED TRANSACTION WHICH IS NOT COVERED
     UNDER AN INDIVIDUAL OR CLASS PROHIBITED TRANSACTION EXEMPTION, INCLUDING,
     BUT NOT LIMITED TO, PROHIBITED TRANSACTION EXEMPTION ("PTE") 84-14, PTE
     91-38, PTE 90-1, PTE 95-60 OR PTE 96-23 AND (II) WILL NOT GIVE RISE TO ANY
     ADDITIONAL FIDUCIARY DUTIES ON THE PART OF THE SERVICER OR THE TRUSTEE,
     WHICH WILL BE DEEMED REPRESENTED BY AN OWNER OF A BOOK-ENTRY CERTIFICATE OR
     A GLOBAL CERTIFICATE AND WILL BE EVIDENCED BY A REPRESENTATION TO SUCH
     EFFECT BY OR ON BEHALF OF A HOLDER OF A PRIVATE CERTIFICATE.

     Section 5.03. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES. (a) If (i)
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 (ii) there is delivered to the Trustee such security or
indemnity as it may require to save it harmless, and (iii) the Trustee has not
received notice that such Certificate has been acquired by a third Person, the
Trustee shall sign, countersign and deliver, in exchange for or in lieu of any
such mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and Fractional Undivided Interest but in each case bearing a different
number. The mutilated, destroyed, lost or stolen Certificate shall thereupon be
canceled of record by the Trustee and shall be of no further effect and evidence
no rights.

     (b) Upon the issuance of any new Certificate under this Section 5.03, the
Trustee may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any duplicate Certificate issued pursuant to this Section 5.03 shall constitute
complete and indefeasible evidence of ownership in the Trust Fund, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

     Section 5.04. PERSONS DEEMED OWNERS. Prior to due presentation of a
Certificate for registration of transfer, the Seller, the Trustee and any agent
of the Seller or the Trustee may treat the Person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 6.01 and for all other purposes whatsoever.
Neither the Seller, the Trustee nor any agent of the Seller or the Trustee shall
be affected by notice to the contrary. No Certificate shall be deemed duly
presented for a transfer effective on any Record Date unless the Certificate to
be transferred is presented no later than the close of business on the third
Business Day preceding such Record Date.

     Section 5.05. TRANSFER RESTRICTIONS ON RESIDUAL CERTIFICATES. (a) Residual
Certificates, or interests therein, may not be transferred without the prior
express written consent of the Tax Matters Person and the Seller. As a
prerequisite to such consent, the proposed transferee must provide the Tax
Matters Person, the Seller and the Trustee with an affidavit that the proposed
transferee is not a Disqualified Organization (as defined in Subsection 5.05(b))
(and, unless the Tax Matters Person and the Seller consent to the transfer to a
person who is not a U.S. Person, an affidavit that it is a U.S. Person) as
provided in Subsection 5.05(b).

     (b) No transfer, sale or other disposition of a Residual Certificate
(including a beneficial interest therein) may be made unless, prior to the
transfer, sale or other disposition of a Residual Certificate, the proposed
transferee (including the initial purchasers thereof) delivers to the Tax
Matters Person, the Trustee and the Seller an affidavit in the form attached
hereto as Exhibit E stating, among other things, that as of the date of such
transfer (i) such transferee is not any of (A) the United States, any state or
political subdivision thereof, any foreign government, any international
organization, or any agency or instrumentality of any of the foregoing (other
than an instrumentality that is a corporation all of whose activities are
subject to tax under Chapter 1 of Subtitle A of the Code and (except in the case
of Freddie Mac) a majority of whose board of directors is not selected by the
United States, or any state or political subdivision thereof), (B) any
organization that is exempt from any tax imposed by Chapter 1 of Subtitle A of
the Code, other than (x) a tax-exempt farmers' cooperative within the meaning of
Section 521 of the Code or (y) an organization that is subject to the tax
imposed by Section 511 of the Code on "unrelated business taxable income" or (C)
a corporation operating on a cooperative basis that is engaged in furnishing
electric energy or providing telephone service to persons in rural areas (within
the meaning of Section 1381(a)(2)(C) of the Code) (any Person described in (A),
(B), or (C) being referred to herein as a "Disqualified Organization") and that
(ii) such transferee is not acquiring such Residual Certificate for the account
of a Disqualified Organization. The Tax Matters Person shall not consent to a
transfer of a Residual Certificate if it has actual knowledge that any statement
made in the affidavit issued pursuant to the preceding sentence is not true.
Notwithstanding any transfer, sale or other disposition of a Residual
Certificate to a Disqualified Organization, such transfer, sale or other
disposition shall be deemed to be of no legal force or effect whatsoever and
such Disqualified Organization shall not be deemed to be a Holder of a Residual
Certificate for any purpose hereunder, including, but not limited to, the
receipt of distributions thereon. If any purported transfer shall be in
violation of the provisions of this Subsection 5.05(b), then the prior Holder
thereof shall, upon discovery that the transfer of such Residual Certificate was
not in fact permitted by this Subsection 5.05(b), be restored to all rights as a
Holder thereof retroactive to the date of the purported transfer. None of the
Trustee, the Tax Matters Person or the Seller shall be under any liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 5.05(b) or for making payments due on such
Residual Certificate to the purported Holder thereof or taking any other action
with respect to such purported Holder under the provisions of this Agreement so
long as the written affidavit referred to above was received with respect to
such transfer, and the Tax Matters Person, the Trustee and the Seller, as
applicable, had no knowledge that it was untrue. The prior Holder shall be
entitled to recover from any purported Holder of a Residual Certificate that was
in fact not a permitted transferee under this Subsection 5.05(b) at the time it
became a Holder all payments made on such Residual Certificate. Each Holder of a
Residual Certificate, by acceptance thereof, shall be deemed for all purposes to
have consented to the provisions of this Subsection 5.05(b) and to any amendment
of this Agreement deemed necessary (whether as a result of new legislation or
otherwise) by counsel of the Tax Matters Person or the Seller to ensure that the
Residual Certificates are not transferred to a Disqualified Organization and
that any transfer of such Residual Certificates will not cause the imposition of
a tax upon the Trust or cause any REMIC to fail to qualify as a real estate
mortgage investment conduit under Section 860D of the Code.

     (c) Unless the Tax Matters Person shall have consented in writing (which
consent may be withheld in the Tax Matters Person's sole discretion), the
Residual Certificates (including a beneficial interest therein) may not be
purchased by or transferred to any person who is not a "United States person,"
as such term is defined in Section 7701(a)(30) of the Code.

     (d) By accepting a Residual Certificate, the purchaser thereof agrees to be
a Tax Matters Person, and appoints the respective Servicer to act as its agent
with respect to all matters concerning the tax obligations of the Trust.

     Section 5.06. RESTRICTIONS ON TRANSFERABILITY OF PRIVATE CERTIFICATES. (a)
No offer, sale, transfer or other disposition (including pledge) of a Private
Certificate shall be made by any Holder thereof unless registered under the
Securities Act, or an exemption from the registration requirements of the
Securities Act and any applicable state securities or "Blue Sky" laws is
available and the prospective transferee (other than the Seller) of such
Certificate signs and delivers to the Trustee an Investment Letter, if the
transferee is an Institutional Accredited Investor, in the form set forth as
Exhibit F-1 hereto, or a Rule 144A Certificate, if the transferee is a QIB, in
the form set forth as Exhibit F-2 hereto. Notwithstanding the provisions of the
immediately preceding sentence, no restrictions shall apply with respect to the
transfer or registration of transfer of a beneficial interest in a Physical
Certificate that is a Global Certificate of a Class to a transferee that takes
delivery in the form of a beneficial interest in the Global Certificate of such
Class provided that each such transferee shall be deemed to have made such
representations and warranties contained in the Rule 144A Certificate as are
sufficient to establish that it is a QIB. In the case of a proposed transfer of
a Private Certificate to a transferee other than a QIB, the Trustee may require
an Opinion of Counsel that such transaction is exempt from the registration
requirements of the Securities Act. The cost of such opinion shall not be an
expense of the Trustee or the Trust Fund.

     (b) Each Private Certificate shall bear a Securities Legend.

     Section 5.07. ERISA RESTRICTIONS. (a) Subject to the provisions of
subsection (b), no Class of Private Certificates may be acquired directly or
indirectly by, or on behalf of, an employee benefit plan or other retirement
arrangement which is subject to Title I of ERISA and/or Section 4975 of the
Code, unless the proposed transferee provides a representation to the Trustee
(upon which the Trustee is authorized to rely) to the effect that the proposed
transfer and/or holding of a Certificate and the servicing, management and
operation of the Trust: (i) will not result in a prohibited transaction under
Section 406 of ERISA or Section 4975 of the Code which is not covered under an
individual or class prohibited transaction exemption including but not limited
to Department of Labor Prohibited Transaction Exemption ("PTE") 84-14 (Class
Exemption for Plan Asset Transactions Determined by Independent Qualified
Professional Asset Managers); PTE 91-38 (Class Exemption for Certain
Transactions Involving Bank Collective Investment Funds); PTE 90-1 (Class
Exemption for Certain Transactions Involving Insurance Company Pooled Separate
Accounts), PTE 95-60 (Class Exemption for Certain Transactions Involving
Insurance Company General Accounts), and PTCE 96-23 (Class Exemption for Plan
Asset Transactions Determined by In-House Asset Managers) and (ii) will not give
rise to any additional fiduciary duties under ERISA on the part of either any
Servicer or the Trustee.

     (b) Any Person acquiring an interest in a Book-Entry Certificate or a
Global Certificate which is a Subordinate Certificate, by acquisition of such
Certificate, shall be deemed to have represented to the Trustee that it is
either: (i) not acquiring an interest in such Certificate directly or indirectly
by, or on behalf of, an employee benefit plan or other retirement arrangement
which is subject to Title I of ERISA and/or Section 4975 of the Code, or (ii)
such Person provides a representation or certification to the Trustee to the
effect that the transfer and/or holding of an interest in such Certificate and
the servicing, management and/or operation of the Trust and its assets: (I) will
not result in any prohibited transaction which is not covered under an
individual or class prohibited transaction exemption, including, but not limited
to, PTE 84-14, PTE 91-38, PTE 90-1, PTE 95-60 or PTE 96-23 and (II) will not
give rise to any additional fiduciary duties on the part of either any Servicer
or the Trustee.

     Section 5.08. RULE 144A INFORMATION. For so long as any Private
Certificates are outstanding and are "restricted securities" within the meaning
of Rule 144(a)(3) of the Securities Act, (1) the Seller will provide or cause to
be provided to any holder of such Certificates and any prospective purchaser
thereof designated by such a holder, upon the request of such holder or
prospective purchaser, the information required to be provided to such holder or
prospective purchaser by Rule 144A(d)(4) under the Securities Act; and (2) the
Seller shall update such information from time to time in order to prevent such
information from becoming false and misleading and will take such other actions
as are necessary to ensure that the safe harbor exemption from the registration
requirements of the Securities Act under Rule 144A is and will be available for
resales of such Certificates conducted in accordance with Rule 144A.

                         Payments to Certificateholders

     Section 6.01. DISTRIBUTIONS ON THE CERTIFICATES. (a) Interest and principal
on the Certificates will be distributed monthly on each Distribution Date,
commencing in May 1998, in an aggregate amount equal to the Available Funds for
such Distribution Date.

     (i) SENIOR CERTIFICATES. (A) On each Distribution Date, the Available Funds
     will be distributed in the following order of priority among the Senior
     Certificates except as otherwise noted and subject to the provisions of
     Section 6.01(c):

          FIRST, to the Senior Certificates, the Accrued Certificate Interest on
          each such Class for such Distribution Date. As described below,
          Accrued Certificate Interest on each Class is subject to reduction in
          the event of certain Net Interest Shortfalls allocable thereto. Any
          Net Interest Shortfalls shall be allocated among the Senior
          Certificates as provided under 6.01(e);

          SECOND, to the Senior Certificates, any Accrued Certificate Interest
          thereon remaining undistributed from previous Distribution Dates, to
          the extent of remaining Available Funds, any shortfall in available
          amounts being allocated among such Classes in proportion to the amount
          of such Accrued Certificate Interest remaining undistributed for each
          such Class for such Distribution Date;

          THIRD, to the Senior Certificates in reduction of the Current
          Principal Amounts thereof:

               (a)  Senior Optimal Principal Amount, in the following order of
                    priority:

                    first, concurrently to the Class R-1, Class R-2 and Class
                    R-3 Certificates, PRO RATA, based upon their Current
                    Principal Amounts until their respective Current Principal
                    Amounts thereof have been reduced to zero;

                    second, concurrently to the Class A-1, Class A-2 and Class
                    A-3 Certificates in the percentages of 10.8331337415%,
                    51.8280562697% and 37.3388099888% respectively, until the
                    Current Principal Amount of the Class A-3 Certificates has
                    been reduced to zero;

                    third, concurrently to the Class A-1, Class A-2 and Class
                    A-4 Certificates, in percentages of 10.8331337415%,
                    51.8280562697% and 37.3388099888%, respectively, until the
                    Current Principal Amount of the Class A-1 Certificates has
                    been reduced to zero;

                    fourth, concurrently to the Class A-2 and Class A-4
                    Certificates in the percentages of 51.8280562697% and
                    48.1719437303%, respectively, until the Current Principal
                    Amounts of the Class A-2 and Class A-4 Certificates have
                    been reduced to zero;

            (B)  On each Distribution Date after the Cross-Over Date,
                 distributions of principal on the outstanding Senior
                 Certificates will be made pro rata among all Senior
                 Certificates, regardless of the allocation, or sequential
                 nature, of principal payments described in priority THIRD
                 above, based upon the then Current Principal Amounts of such
                 Senior Certificates.

        (ii)   SUBORDINATE CERTIFICATES. On each Distribution Date, subject to
               the provisions of Section 6.01(c), the Available Funds remaining
               after the distributions described above under Section 6.01(a)(i)
               will be distributed among the Subordinate Certificates
               sequentially, in the following order, to the Class B-1, Class
               B-2, Class B-3, Class B-4, Class B-5 and Class B-6 Certificates,
               in each case up to an amount equal to and in the following order:
               (a) the Accrued Certificate Interest thereon for such
               Distribution Date, (b) any Accrued Certificate Interest thereon
               remaining undistributed from previous Distribution Dates and (c)
               such Class's Allocable Share for such Distribution Date.

     (b) "Pro rata" distributions among Classes of Certificates will be made in
proportion to the then Current Principal Amount of such Classes.

     (c) On each Distribution Date, any Available Funds remaining after payment
of interest and principal as described above will be distributed, to the Class
R-1 Certificates; provided, however, that if the Available Funds are
insufficient to pay the entire amount required to be paid on such Distribution
Date, the amount payable to the Class R-1 Certificates pursuant to this
subclause (c) shall instead be paid to the other Certificates, pro rata based
upon the amount of such shortfalls.

     (d) No Accrued Certificate Interest will be payable with respect to any
Class of Certificates after the Distribution Date on which the Current Principal
Amount of such Certificate has been reduced to zero.

     (e) If on any Distribution Date the Available Funds for the Senior
Certificates is less than the Accrued Certificate Interest on the Senior
Certificates for such Distribution Date prior to reduction for Net Interest
Shortfall and the interest portion of Realized Losses, the shortfall will be
allocated among the holders of each Class of Senior Certificates in proportion
to the respective amounts of Accrued Certificate Interest that would have been
allocated thereto in the absence of such Net Interest Shortfall and/or Realized
Losses for such Distribution Date. In addition, the amount of any interest
shortfalls will constitute unpaid Accrued Certificate Interest and will be
distributable to holders of the Certificates of the related Classes entitled to
such amounts on subsequent Distribution Dates, to the extent of the applicable
Available Funds after current interest distributions as required herein. Any
such amounts so carried forward will not bear interest. Shortfalls in interest
payments will not be offset by a reduction in the servicing compensation of the
Servicers or otherwise, except to the extent of applicable Compensating Interest
Payments.

     (f) On each Distribution Date, the funds available for distribution shall
be allocated to distributions on each of the REMIC II and REMIC III Regular
Interests in an amount sufficient to make the distributions on the corresponding
Certificates on such Distribution Date in accordance with the provisions of
subsection (a) of this Section 6.01 and Section 5.01, unless specifically
provided otherwise in this Agreement.

     (g) The expenses and fees of the Trust shall be paid by each of REMIC II
and REMIC III, respectively, to the extent that such expenses relate to the
assets for each of such respective REMICs, and all other expenses and fees of
the Trust shall be paid pro rata by each of REMIC II and REMIC III.

     Section 6.02. ALLOCATION OF LOSSES. (a) On or prior to each Determination
Date, the Servicer shall determine the amount of any Realized Loss in respect of
each Mortgage Loan that occurred during the immediately preceding calendar
month.

     (b) (i) With respect to any Certificates on any Determination Date, the
     principal portion of each Realized Loss on a Mortgage Loan (other than any
     Excess Loss) shall be allocated as follows:

                    first, to the Class B-6 Certificates until the Current
     Principal Amount thereof has been reduced to zero;

                    second, to the Class B-5 Certificates until the Current
     Principal Amount thereof has been reduced to zero;

                    third, to the Class B-4 Certificates until the Current
     Principal Amount thereof has been reduced to zero;

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

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

                    sixth, to the Class B-1 Certificates until the Current
     Principal amount thereof has been reduced to zero;

                    seventh, to the Classes of Senior Certificates, pro rata, in
     accordance with their Current Principal Amounts.

          (ii) With respect to any Distribution Date, the principal portion of
     any Excess Loss (other than those attributable to Debt Service Reductions)
     shall be allocated among all Classes of Certificates, pro rata, based on
     the respective Current Principal Amounts thereof.

          (iii) Notwithstanding the foregoing, no such allocation of any
     Realized Loss shall be made on a Distribution Date to any Class of
     Certificates to the extent that such allocation would result in the
     reduction of the aggregate Current Principal Amounts of all the
     Certificates as of such Distribution Date, after giving effect to all
     distributions and prior allocations of Realized Losses on such date, to an
     amount less than the aggregate Scheduled Principal Balance of all of the
     Mortgage Loans as of the first day of the month of such Distribution Date,
     less any Deficient Valuations occurring on or prior to the Bankruptcy
     Coverage Termination Date (such limitation, the "Loss Allocation
     Limitation").

     (c) Any Realized Losses allocated to a Class of Certificates shall be
allocated among the Certificates of such Class in proportion to their respective
Current Principal Amounts. Any allocation of Realized Losses shall be
accomplished by reducing the Current Principal Amount of the related
Certificates on the related Distribution Date.

     (d) Realized Losses shall be allocated on the Distribution Date in the
month following the month in which such loss was incurred and, in the case of
the principal portion thereof, after giving effect to distributions made on such
Distribution Date.

     (e) On each Distribution Date, the Trustee shall determine the Subordinate
Certificate Writedown Amount. Any such Subordinate Certificate Writedown Amount
shall effect a corresponding reduction in the Current Principal Amount of (i) if
prior to the Cross-Over Date, the Current Principal Amounts of the Subordinate
Certificates, in the reverse order of their numerical Class designations and
(ii) from and after the Cross-Over Date, the Senior Certificates, pro rata based
on their respective Current Principal Amounts, which reduction shall occur on
such Distribution Date after giving effect to distributions made on such
Distribution Date.

     (f) The interest portion of any Realized Losses occurring on or prior to
the Cross- Over Date will not be allocated among any Certificates, but will
reduce the amount of Available Funds on the related Distribution Date. As a
result of the subordination of the Subordinate Certificates, in right of
distribution, such Realized Losses will be borne first by the Subordinate
Certificates in inverse order of their numerical Class designations.

     Section 6.03. PAYMENTS. (a) On each Distribution Date, other than the final
Distribution Date, the Trustee shall distribute to each Certificateholder of
record on the directly preceding Record Date the Certificateholder's PRO RATA
share of its Class (based on the aggregate Fractional Undivided Interest
represented by such Holder's Certificates) of all amounts required to be
distributed on such Distribution Date to such Class. The Trustee shall calculate
the amount to be distributed to each Class and, based on such amounts, the
Trustee shall determine the amount to be distributed to each Certificateholder.
All of the Trustee's calculations of payments shall be based solely on
information provided to the Trustee by the Servicers. The Trustee shall not be
required to confirm, verify or recompute any such information but shall be
entitled to rely conclusively on such information.

     (b) Payment of the above amounts to each Certificateholder shall be made
(i) by check mailed to each Certificateholder entitled thereto at the address
appearing in the Certificate Register or (ii) upon receipt by the Trustee on or
before the fifth Business Day preceding the Record Date of written instructions
from a Certificateholder holding Certificates representing an initial aggregate
Current Principal Amount of not less than $1,000,000 by wire transfer to a
United States dollar account maintained by the payee at any United States
depository institution with appropriate facilities for receiving such a wire
transfer; PROVIDED, HOWEVER, that the final payment in respect of each Class of
Certificates will be made only upon presentation and surrender of such
respective Certificates at the office or agency of the Trustee specified in the
notice to Certificateholders of such final payment.

     Section 6.04. STATEMENTS TO CERTIFICATEHOLDERS. (a) Concurrently with each
distribution to Certificateholders, the Trustee shall forward by first-class

     at the related Pass-Through Rate necessary to account for any difference

by the Servicers. The Trustee may conclusively rely on such information and
shall not be required to confirm, verify or recalculate any such information.

     (b) By April 30 of each year beginning in 1999, the Trustee will furnish a

respect to the amount of servicing compensation and such other customary
information as the Trustee may determine to be necessary and/or to be required

will be obligated to make a Monthly Advance by deposit into the Certificate
Account, except to the extent BSMCC determines any such advance to be
nonrecoverable from Liquidation Proceeds, Insurance Proceeds or from future
payments on the Mortgage Loan for which the advance was made. No later than the
second Business Day prior to each Distribution Date, BSMCC shall deliver a
report to the Trustee on any BA Mortgage Loan which is more than 120 days
delinquent stating whether BSMCC is obligated to make a Monthly Advance or is
not obligated because BSMCC has determined such advance would be nonrecoverable.
The Trustee shall be obligated to make such Monthly Advance on the Distribution
Date if BSMCC is obligated to make a Monthly Advance but fails to do so. BSMCC
or the Trustee shall be reimbursed for any Monthly Advance in the same manner
that BA would be reimbursed for a Monthly Advance.

provided for therein and shall thereafter be subject to all the
responsibilities, duties, liabilities and limitations on liabilities relating
thereto placed on the Servicer by the terms and provisions thereof; PROVIDED,
HOWEVER, that the Trustee (i) shall be under no obligation to purchase any
Mortgage Loan; and (ii) shall have no obligation whatsoever with respect to any
liability (other than advances deemed recoverable and not previously made)
incurred by the Servicer at or prior to the time of termination. As compensation
therefor, the Trustee shall be entitled to all funds relating to the Mortgage
Loans which the Servicer would have been entitled to retain if the Servicer had
continued to act hereunder, except for those amounts due the Servicer as
reimbursement for advances previously made or expenses previously incurred.
Notwithstanding the above, the Trustee may, if it shall be unwilling so to act,
or shall, if it is legally unable so to act, appoint or petition a court of
competent jurisdiction to appoint, any established housing and home finance
institution which is a FNMA- or Freddie Mac-approved servicer having a net worth
of not less than $10,000,000. 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 the
Mortgage Loans as it and such successor shall agree; PROVIDED, HOWEVER, that no
such compensation shall be in excess of that permitted the Trustee under this
Subsection 8.02(a), and that such successor shall undertake and assume the
obligations of the Trustee to pay compensation to any third Person acting as an
agent or independent contractor in the performance of servicing responsibilities
hereunder. The Trustee and such successor shall take such action, consistent
with this Agreement and the Servicing Agreement, as shall be necessary to
effectuate any such succession.

     (b) If the Trustee shall succeed to any duties of the Servicer respecting
the Mortgage Loans as provided herein, it shall do so in a separate capacity and
not in its capacity as Trustee and, accordingly, the provisions of Article IX
shall be inapplicable to the Trustee in its duties as the successor to the
Servicer in the servicing of the Mortgage Loans (although such provisions shall
continue to apply to the Trustee in its capacity as Trustee); the provisions of
Article VII, however, shall apply to it in its capacity as successor servicer.

     Section 8.03. NOTIFICATION TO CERTIFICATEHOLDERS. Upon any termination or
appointment of a successor to the Servicer, the Trustee shall give prompt
written notice thereof to Certificateholders at their respective addresses
appearing in the Certificate Register and to the Rating Agencies.

     Section 8.04. WAIVER OF DEFAULTS. The Trustee shall transmit by mail to all
Certificateholders, within 60 days after the occurrence of any Event of Default
known to the Trustee, unless such Event of Default shall have been cured, notice
of each such Event of Default hereunder known to the Trustee. The Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
51% of the Trust Fund may, on behalf of all Certificateholders, waive any
default by the Servicer in the performance of its obligations hereunder and the
consequences thereof, except a default in the making of or the causing to be
made any required distribution on the Certificates. Upon any such waiver of a
past default, such default shall be deemed to cease to exist, and any Event of
Default arising therefrom shall be deemed to have been timely remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived. The Trustee shall give notice of any such waiver to the
Rating Agencies.

     Section 8.05. LIST OF CERTIFICATEHOLDERS. Upon written request of three or
more Certificateholders of record, for purposes of communicating with other
Certificateholders with respect to their rights under this Agreement, the
Trustee will afford such Certificateholders access during business hours to the
most recent list of Certificateholders held by the Trustee.

                                   ARTICLE IX

                             Concerning the Trustee

     Section 9.01. DUTIES OF TRUSTEE. (a) The Trustee, prior to the occurrence
of an Event of Default and after the curing or waiver of all Events of Default
which may have occurred, undertakes to perform such duties and only such duties
as are specifically set forth in this Agreement as duties of the Trustee. If an
Event of Default has occurred and has not been cured or waived, the Trustee
shall exercise such of the rights and powers vested in it by this Agreement, and
subject to Section 8.02(b) use the same degree of care and skill in their
exercise, as a prudent person would exercise under the circumstances in the
conduct of his own affairs.

     (b) Upon receipt of all resolutions, certificates, statements, opinions,
reports, documents, orders or other instruments which are specifically required
to be furnished to the Trustee pursuant to any provision of this Agreement, the
Trustee shall examine them to determine whether they are in the form required by
this Agreement; PROVIDED, HOWEVER, that the Trustee shall not be responsible for
the accuracy or content of any resolution, certificate, statement, opinion,
report, document, order or other instrument furnished by any Servicer; PROVIDED,
FURTHER, that the Trustee shall not be responsible for the accuracy or
verification of any calculation provided to it pursuant to this Agreement.

     (c) The Trustee shall make monthly distributions and the final distribution
to the Certificateholders as provided in Sections 6.01 and 10.01 herein.

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

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

          (ii) The Trustee shall not be liable in its individual capacity 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 liable with respect to any action
     taken, suffered or omitted to be taken by it in good faith in accordance
     with the directions of the Holders of Certificates evidencing Fractional
     Undivided Interests aggregating not less than 25% of the Trust Fund, if
     such action or non-action relates to the time, method and place of
     conducting any proceeding for any remedy available to the Trustee, or
     exercising any trust or other power conferred upon the Trustee, under this
     Agreement;

          (iv) The Trustee shall not be required to take notice or be deemed to
     have notice or knowledge of any default or Event of Default unless a
     Responsible Officer of the Trustee's Corporate Trust Office shall have
     actual knowledge thereof. In the absence of such notice, the Trustee may
     conclusively assume there is no such default or Event of Default;

          (v) The Trustee shall not in any way be liable by reason of any
     insufficiency in any Account held by or in the name of Trustee unless it is
     determined by a court of competent jurisdiction that the Trustee's gross
     negligence or willful misconduct was the primary cause of such
     insufficiency; and

          (vi) Anything in this Agreement to the contrary notwithstanding, in no
     event shall the Trustee be liable for special, indirect or consequential
     loss or damage of any kind whatsoever (including but not limited to lost
     profits), even if the Trustee has been advised of the likelihood of such
     loss or damage and regardless of the form of action.

     The Trustee shall not be required to expend or risk its own funds or
otherwise incur financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if there is
reasonable ground for believing that the repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it, and
none of the provisions contained in this Agreement shall in any event require
the Trustee to perform, or be responsible for the manner of performance of, any
of the obligations of any Servicer under any Servicing Agreement, except during
such time, if any, as the Trustee shall be the successor to, and be vested with
the rights, duties, powers and privileges of, any Servicer in accordance with
the terms of this Agreement.

     (e) All funds received by the Trustee and required to be deposited in the
Certificate Account pursuant to this Agreement will be promptly so deposited by
the Trustee.

     (f) Except for those actions that the Trustee is required to take
hereunder, the Trustee shall have no obligation or liability to take any action
or to refrain from taking any action hereunder in the absence of written
direction as provided hereunder.

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

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

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

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

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

          (v) 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
     Holders of Certificates evidencing Fractional Undivided Interests
     aggregating not less than 25% of the Trust Fund and provided that the
     payment within a reasonable time to the Trustee of the costs, expenses or
     liabilities likely to be incurred by it in the making of such investigation
     is, in the opinion of the Trustee, reasonably assured to the Trustee by the
     security afforded to it by the terms of this Agreement. The Trustee may
     require reasonable indemnity against such expense or liability as a
     condition to taking any such action. The reasonable expense of every such
     examination shall be paid by the Certificateholders requesting the
     investigation;

          (vi) The Trustee may execute any of the trusts or powers hereunder or
     perform any duties hereunder either directly or through agents or
     attorneys; PROVIDED, HOWEVER, that the Trustee may not appoint any agent to
     perform its custodial functions with respect to the Mortgage Files or
     paying agent functions under this Agreement without the express written
     consent of any Servicer, which consent will not be unreasonably withheld.
     The Trustee shall not be liable or responsible for the misconduct or
     negligence of any of the Trustee's agents or attorneys or a custodian or
     paying agent appointed hereunder by the Trustee with due care and, when
     required, with the consent of any Servicer;

          (vii) Should the Trustee deem the nature of any action required on its
     part, other than a payment or transfer under Subsection 4.01(b) or Section
     4.02, to be unclear, the Trustee may require prior to such action that it
     be provided by the Seller with reasonable further instructions;

          (viii) 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 accountable for other than its negligence or willful
     misconduct in the performance of any such act;

          (ix) The Trustee shall not be required to give any bond or surety with
     respect to the execution of the trust created hereby or the powers granted
     hereunder; and

          (x) The Trustee shall have no duty to conduct any affirmative
     investigation as to the occurrence of any condition requiring the
     repurchase of any Mortgage Loan by BSMCC, Dime, FBS or Chemical pursuant to
     this Agreement, Mortgage Loan Purchase Agreement, the Dime Sale Agreement
     or any Servicing Agreement or the eligibility of any Mortgage Loan for
     purposes of this Agreement.

     Section 9.03. TRUSTEE NOT LIABLE FOR CERTIFICATES OR MORTGAGE LOANS. The
recitals contained herein and in the Certificates (other than the signature and
countersignature of the Trustee on the Certificates) shall be taken as the
statements of the Seller, and the Trustee shall have no responsibility for their
correctness. The Trustee makes no representation as to the validity or
sufficiency of the Certificates (other than the signature and countersignature
of the Trustee on the Certificates) or of any Mortgage Loan except as expressly
provided in Sections 2.02 and 2.05 hereof; provided, however, that the foregoing
shall not relieve the Trustee of the obligation to review the Mortgage Files
pursuant to Sections 2.02 and 2.04. The Trustee's signature and countersignature
(or countersignature of its agent) on the Certificates shall be solely in its
capacity as Trustee and shall not constitute the Certificates an obligation of
the Trustee in any other capacity. The Trustee shall not be accountable for the
use or application by the Seller 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 with respect to the Mortgage Loans. Subject to the provisions of Section
2.05, the Trustee shall not be responsible for the legality or validity of this
Agreement or any document or instrument relating to this Agreement, the validity
of the execution of this Agreement or of any supplement hereto or instrument of
further assurance, or the validity, priority, perfection or sufficiency of the
security for the Certificates issued hereunder or intended to be issued
hereunder. The Trustee shall at no time have any responsibility or liability for
or with respect to the legality, validity and enforceability of any Mortgage or
any Mortgage Loan, or the perfection and priority of any Mortgage or the
maintenance of any such perfection and priority, or for or with respect to the
sufficiency of the Trust Fund or its ability to generate the payments to be
distributed to Certificateholders, under this Agreement. The Trustee shall have
no responsibility for filing any financing or continuation statement in any
public office at any time or to otherwise perfect or maintain the perfection of
any security interest or lien granted to it hereunder or to record this
Agreement.

     Section 9.04. TRUSTEE MAY OWN CERTIFICATES. The Trustee in its individual
capacity or in any capacity other than as Trustee hereunder may become the owner
or pledgee of any Certificates with the same rights it would have if it were not
Trustee, and may otherwise deal with the parties hereto.

     Section 9.05. TRUSTEE'S FEES AND EXPENSES. The Seller covenants and agrees
to pay to the Trustee the Trustee's Fees as set forth in, and in accordance
with, such understanding as may be agreed to between such parties. Such
compensation obligation shall not be limited by any provision of law in regard
to the compensation of a trustee of an express trust.

     Section 9.06. ELIGIBILITY REQUIREMENTS FOR TRUSTEE. The Trustee and any
successor Trustee shall during the entire duration of this Agreement be a state
bank or trust company or a national banking association organized and doing
business under the laws of such state or the United States of America,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus and undivided profits of at least $40,000,000 or, in the
case of a successor Trustee, $50,000,000, subject to supervision or examination
by federal or state authority and, in the case of a successor Trustee other than
pursuant to Section 9.10, rated in one of the two highest long-term debt
categories of, or otherwise acceptable to, each of the Rating Agencies. The
Trustee shall not be an Affiliate of any Servicer, unless the Trustee acts as
successor Servicer hereunder. If the Trustee 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 9.06
the combined capital and surplus of such corporation shall be deemed to be its
total equity capital (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 9.06, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 9.08.

     Section 9.07. INSURANCE. The Trustee, at its own expense, shall at all
times maintain and keep in full force and effect: (i) fidelity insurance, (ii)
theft of documents insurance and (iii) forgery insurance (which may be
collectively satisfied by a "Financial Institution Bond" and/or a "Bankers'
Blanket Bond"). All such insurance shall be in amounts, with standard coverage
and subject to deductibles, as are customary for insurance typically maintained
by banks which act as custodians for investor-owned mortgage pools. A
certificate of an officer of the Trustee as to the Trustee's compliance with
this Section 9.07 shall be furnished to any Certificateholder upon reasonable
written request.

     Section 9.08. RESIGNATION AND REMOVAL OF THE TRUSTEE. (a) The Trustee may
at any time resign and be discharged from the Trust hereby created by giving
written notice thereof to the Seller and any Servicer, with a copy to the Rating
Agencies. Upon receiving such notice of resignation, the Seller shall promptly
appoint a successor Trustee by written instrument, in triplicate, one copy of
which instrument shall be delivered to each of the resigning Trustee and the
successor Trustee. If no successor Trustee shall have been so appointed and have
accepted appointment within 30 days after the giving of such notice of
resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

     (b) If at any time the Trustee shall cease to be eligible in accordance
with the provisions of Section 9.06 and shall fail to resign after written
request therefor by the Seller or if at any time the Trustee shall become
incapable of acting, or shall be adjudged a bankrupt or insolvent, or a receiver
of the Trustee or of its property shall be appointed, or any public officer
shall take charge or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, then the Seller
shall be entitled to remove the Trustee and appoint a successor Trustee by
written instrument, in triplicate, one copy of which instrument shall be
delivered to each of the Trustee so removed and the successor Trustee.

     (c) The Holders of Certificates evidencing Fractional Undivided Interests
aggregating not less than 51% of the Trust Fund may at any time remove the
Trustee and appoint a successor Trustee by written instrument or instruments, in
quadruplicate, signed by such Holders or their attorneys-in-fact duly
authorized, one complete set of which instruments shall be delivered to the
Seller, the Servicer, the Trustee so removed and the successor so appointed.

     (d) No resignation or removal of the Trustee and appointment of a successor
Trustee pursuant to any of the provisions of this Section 9.08 shall become
effective except upon appointment of and acceptance of such appointment by the
successor Trustee as provided in Section 9.09.

     Section 9.09. SUCCESSOR TRUSTEE. (a) Any successor Trustee appointed as
provided in Section 9.08 shall execute, acknowledge and deliver to the Seller
and to its predecessor Trustee an instrument accepting such appointment
hereunder. The resignation or removal of the predecessor Trustee shall then
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 like effect as if originally
named as Trustee herein. The predecessor Trustee shall after payment of its
outstanding fees and expenses promptly deliver to the successor Trustee all
assets and records of the Trust held by it hereunder, and the Seller and the
predecessor Trustee shall execute and deliver such instruments and do such other
things as may reasonably be required for more fully and certainly vesting and
confirming in the successor Trustee all such rights, powers, duties and
obligations.

     (b) No successor Trustee shall accept appointment as provided in this
Section 9.09 unless at the time of such acceptance such successor Trustee shall
be eligible under the provisions of Section 9.06.

     (c) Upon acceptance of appointment by a successor Trustee as provided in
this Section 9.09, the successor Trustee shall mail notice of the succession of
such Trustee hereunder to all Certificateholders at their addresses as shown in
the Certificate Register and to the Rating Agencies. BSMCC shall pay the cost of
any mailing by the successor Trustee.

     Section 9.10. MERGER OR CONSOLIDATION OF TRUSTEE. Any state bank or trust
company or national banking association into which the Trustee may be merged or
converted or with which it may be consolidated or any state bank or trust
company or national banking association resulting from any merger, conversion or
consolidation to which the Trustee shall be a party, or any state bank or trust
company or national banking association succeeding to all or substantially all
of the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, provided such state bank or trust company or national banking
association shall be eligible under the provisions of Section 9.06. Such
succession shall be valid 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 9.11. APPOINTMENT OF CO-TRUSTEE OR SEPARATE Trustee. (a)
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust or property constituting the same may at the time be located, the Seller
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
and the Seller 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, and to
vest in such Person or Persons, in such capacity, such title to the Trust, or
any part thereof, and, subject to the other provisions of this Section 9.11,
such powers, duties, obligations, rights and trusts as the Seller and the
Trustee may consider necessary or desirable.

     (b) If the Seller shall not have joined in such appointment within 15 days
after the receipt by it of a written request so to do, the Trustee shall have
the power to make such appointment without the Seller.

     (c) 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 Certificateholders of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 9.08 hereof.

     (d) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 9.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee and required to be conferred on such
co-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 any 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 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.

     (e) 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.

     (f) To the extent not prohibited by law, any separate trustee or co-trustee
may, at any time, request the Trustee, its agent or attorney-in-fact, with full
power and authority, to do any lawful act under or with respect to 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.

     (g) No trustee under this Agreement shall be personally liable by reason of
any act or omission of another trustee under this Agreement. The Seller and the
Trustee acting jointly may at any time accept the resignation of or remove any
separate trustee or co-trustee.

     Section 9.12. FEDERAL INFORMATION RETURNS AND REPORTS TO
CERTIFICATEHOLDERS. (a) For federal income tax purposes, the taxable year of
each REMIC shall be a calendar year and the Trustee shall maintain or cause the
maintenance of the books of each REMIC on the accrual method of accounting.

     (b) The Trustee shall prepare and the Trustee will file or cause to be
filed with the Internal Revenue Service Federal tax information returns with
respect to each REMIC, the Trust Fund, if applicable, and the Certificates
containing such information and at the times and in the manner as may be
required by the Code or applicable Treasury regulations, and shall furnish to
each Holder of Certificates at any time during the calendar year for which such
returns or reports are made such statements or information at the times and in
the manner as may be required thereby. In connection with the foregoing, the
Trustee shall provide the name and address of the person who can be contacted to
obtain information required to be reported to the holders of regular interests
in each REMIC (the "REMIC Reporting Agent") as required by IRS Form 8811. The
Trustee shall make the elections to treat each REMIC as a real estate mortgage
investment conduit under the Code (which election shall apply to the taxable
period ending December 31, 1998 and each calendar year thereafter) in such
manner as the Code or applicable Treasury regulations may prescribe. The Holder
of the Class R-1 Certificate is hereby designated as the "Tax Matters Person"
(within the meaning of Treas. Reg. ss.ss. 1.860F-4(d)) for REMIC I, the Holder
of the Class R-2 Certificate is hereby designated as "Tax Matters Person" for
REMIC II and the Holder of the Class R-3 Certificate is hereby designated as
"Tax Matters Person" for REMIC III. The Trustee is hereby designated and
appointed as the agent of each such Tax Matters Person. Any Holder of a Residual
Certificate will by acceptance thereof appoint the Trustee as agent and
attorney-in-fact for the purpose of acting as Tax Matters Person for each REMIC
during such time as the Trustee does not own any such Residual Certificate. In
the event that the Code or applicable Treasury regulations prohibit the Trustee
from signing tax or information returns or other statements, or the Trustee from
acting as Tax Matters Person (as an agent or otherwise), the Trustee shall take
whatever action that in its sole good faith judgment is necessary for the proper
filing of such information returns or for the provision of a tax matters person,
including designation of the Holder of a Residual Certificate to sign such
returns or act as tax matters person. Each Holder of a Residual Certificate
shall be bound by this Section.

     (c) The Trustee shall provide upon request and receipt of reasonable
compensation, such information as required in Section 860D(a)(6)(B) of the Code
to the Internal Revenue Service, to any Person purporting to transfer a Residual
Certificate to a Person other than a transferee permitted by Section 5.05(b),
and to any regulated investment company, real estate investment trust, common
trust fund, partnership, trust, estate, organization described in Section 1381
of the Code, or nominee holding an interest in a pass-through entity described
in Section 860E(e)(6) of the Code, any record holder of which is not a
transferee permitted by Section 5.05(b) (or which is deemed by statute to be an
entity with a disqualified member).

         (d) The Trustee shall prepare and the Trustee shall file or cause to be
filed any state income tax returns required under Applicable State Law with
respect to each REMIC or the Trust Fund.

                                   Termination

     Section 10.01. TERMINATION UPON REPURCHASE BY THE SELLER OR ITS DESIGNEE OR
LIQUIDATION OF THE MORTGAGE LOANS. (a) Subject to Section 10.02, the respective
obligations and responsibilities of the Seller and the Trustee created hereby,
other than the obligation of the Trustee to make payments to Certificateholders
as hereinafter set forth shall terminate upon:

     (1) the repurchase by Chase of all the Chase Mortgage Loans and related REO
     Property remaining in the Trust at a price equal to (a) the unpaid
     principal balance of each Mortgage Loan plus accrued and unpaid interest at
     the Mortgage Rate (less any amounts constituting previously unreimbursed
     Monthly Advances) and (b) the appraised value of any REO Property (less the
     good faith estimate of Chase's liquidation expenses incurred in connection
     with its disposal thereof), such appraisal to be conducted by an appraiser
     mutually agreed upon by Chase and the Trustee;

     (2) (i) the repurchase by or at the direction of the Seller or its designee
     of all Mortgage Loans and all REO Property remaining in the Trust at a
     price equal to (a) 100% of the Outstanding Principal Balance of each
     Mortgage Loan (other than a Mortgage Loan related to REO Property) as of
     the date of repurchase, net of the principal portion of any unreimbursed
     Monthly Advances made by the purchaser, together with interest at the
     applicable Mortgage Interest Rate accrued but unpaid through and including
     the last day of the month of repurchase, plus (b) the appraised value of
     any REO Property, less the good faith estimate of the Seller of liquidation
     expenses to be incurred in connection with its disposal thereof (but not
     more than the Outstanding Principal Balance of the related Mortgage Loan,
     together with interest at the applicable Mortgage Interest Rate accrued on
     that balance but unpaid through and including the last day of the month of
     repurchase), such appraisal to be calculated by an appraiser mutually
     agreed upon by the Seller and the Trustee at the expense of the Seller; or

          (ii) the later of the making of the final payment or other
     liquidation, or any advance with respect thereto, of the last Mortgage Loan
     remaining in the Trust Fund or the disposition of all property acquired
     with respect to any Mortgage Loan; PROVIDED, HOWEVER, that in the event
     that an advance has been made, but not yet recovered, at the time of such
     termination, the Person having made such advance shall be entitled to
     receive, notwithstanding such termination, any payments received subsequent
     thereto with respect to which such advance was made.

     (b) In no event, however, shall the Trust created hereby continue beyond
the expiration of 21 years from the death of the last survivor of the
descendants of Joseph P. Kennedy, the late Ambassador of the United States to
the Court of St. James, living on the date of this Agreement.

     (c) (1) The right of Chase to repurchase all the Chase Mortgage Loans
pursuant to Section 10.03 of the Chase Servicing Agreement shall be exercisable
only if the outstanding principal amount of the Chase Mortgage Loans is
$5,000,000 or less.

          (2) The right of the Seller or its designee to repurchase all Mortgage
Loans pursuant to Subsection 10.01(a)(2)(i) above shall be exercisable only if
(i) the aggregate unpaid principal balance of the Mortgage Loans at the time of
any such repurchase is less than 10% of the portion of the Cut-off Date Balance
or (ii) the Seller, based upon an Opinion of Counsel, has determined that the
REMIC status of any REMIC has been lost or that a substantial risk exists that
such REMIC status will be lost for the then-current taxable year. At any time
thereafter, in the case of (i) or (ii) above, the Seller may elect to terminate
the REMIC at any time, and upon such election, the Seller or its designee, shall
repurchase all the Mortgage Loans.

     (d) The Trustee shall give notice of any termination to the
Certificateholders, with a copy to the Rating Agencies, upon which the
Certificateholders shall surrender their Certificates to the Trustee for payment
of the final distribution and cancellation. Such notice shall be given by
letter, mailed not earlier than the 15th day and not later than the 25th day of
the month next preceding the month of such final distribution, and shall specify
(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.

     (e) (1) If the option of Chase to repurchase the Chase Mortgage Loans under
Section 10.03 of the Chase Servicing Agreement is exercised, Chase shall deliver
to the Trustee for deposit in the Certificate Account, by the Servicer
Remittance Date during the following month, an amount equal to the repurchase
price for the Chase Mortgage Loans and related REO Property being purchased by
it.

          (2) If the option of the Seller to repurchase or cause the repurchase
of all Mortgage Loans under Subsection 10.01(a)(2)(i) above is exercised, the
Seller and/or its designee shall deliver to the Trustee for deposit in the
Certificate Account, by the Business Day prior to the applicable Distribution
Date, an amount equal to the repurchase price for the Mortgage Loans being
purchased by it and all property acquired with respect to such Mortgage Loans
remaining in the REMIC.

     Upon the presentation and surrender of the Certificates, the Trustee shall
distribute an amount equal to (i) the amount otherwise distributable to the
Certificateholders (other than the holder of the Class of Residual Certificate)
on such Distribution Date but for such repurchase, (ii) the Current Principal
Amount and any accrued but unpaid interest at the Pass- Through Rate to the
Certificateholders of each Class, and (iii) the remainder to the Class R-1
Certificateholder. If the Available Funds are not sufficient to pay all of the
related Certificates in full, any such deficiency will be allocated to the
outstanding Class or Classes of Subordinate Certificates having the highest
numerical designation or if after the applicable Cross-Over Date to the Senior
Certificates pro rata. Upon deposit of the required repurchase price and
following such final Distribution Date, the Trustee shall release promptly to
the Seller and/or its designee, the Mortgage Files for the remaining Mortgage
Loans, and the Accounts shall terminate, subject to the Trustee's obligation to
hold any amounts payable to Certificateholders in trust without interest pending
final distributions pursuant to Subsection 10.01(g).

     (f) In the event that this Agreement is terminated by reason of the payment
or liquidation of all Mortgage Loans or the disposition of all property acquired
with respect to all Mortgage Loans under Subsection 10.01(a)(ii) above, each
Servicer shall deliver to the Trustee for deposit in the Certificate Account all
distributable amounts remaining in their Protected Accounts. Upon the
presentation and surrender of the Certificates, the Trustee shall distribute to
the Certificateholders, in accordance with their respective interests, all
distributable amounts remaining in the Certificate Account. Upon deposit by each
Servicer of such distributable amounts, and following such final Distribution
Date, the Trustee shall release promptly to the Seller or its designee the
Mortgage Files for the remaining Mortgage Loans, and the Certificate Account
shall terminate, subject to the Trustee's obligation to hold any amounts payable
to the Certificateholders in trust without interest pending final distributions
pursuant to Subsection 10.01(g).

     (g) If not all of the Certificateholders shall surrender their Certificates
for cancellation within six months after the time specified in the
above-mentioned written notice, the Trustee shall give a second written notice
to the remaining Certificateholders to surrender their Certificates for
cancellation and receive the final distribution with respect thereto. If within
six months after the second notice, not all the Certificates shall have been
surrendered for cancellation, the Trustee may take appropriate steps, or appoint
any agent to take appropriate steps, to contact the remaining Certificateholders
concerning surrender of their Certificates, and the cost thereof shall be paid
out of the funds and other assets which remain subject to this Agreement.

     Section 10.02. ADDITIONAL TERMINATION REQUIREMENTS. (a) If the option of
Chase to repurchase the Chase Mortgage Loans under Section 10.03 of the Chase
Servicing Agreement or if the option of the Seller to repurchase all the
Mortgage Loans under Subsection 10.01(a)(2)(i) above is exercised, REMIC III in
the case of the Chase repurchase and REMIC II (and REMIC III if it is still in
existence) in the case of the Seller's repurchase and REMIC I if it is to be
terminated pursuant to Subsection 10.02(c) 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
to comply with the requirements of this Section 10.02 will not (i) result in the
imposition of taxes on "prohibited transactions" as defined in Section 860F of
the Code on any REMIC or (ii) cause any REMIC to fail to qualify as a REMIC at
any time that any Regular Certificates are outstanding:

          (i) within 90 days prior to the final Distribution Date of any REMIC,
     at the written direction of Chase or the Seller, the Trustee, as agent for
     the respective Tax Matters Persons, shall adopt a plan of complete
     liquidation of any REMIC provided to it by Chase or the Seller meeting the
     requirements of a "Qualified Liquidation" under Section 860F of the Code
     and any regulations thereunder.

          (ii) at or after the time of adoption of such a plan of complete
     liquidation of any of the REMICs and at or prior to the final Distribution
     Date, the Trustee shall sell for cash all of the assets of the REMIC to
     Chase or to or at the direction of the Seller; and

          (iii) at the time of the making of the final payment on any
     Certificates, the Trustee shall distribute or credit from the Certificate
     Account (or cause to be distributed or credited) (i) to the
     Certificateholders, other than the Holder of the corresponding Residual
     Certificates, the Current Principal Amount of the Certificates plus 30
     days' interest thereon at the applicable Pass-Through Rate, and (ii) to the
     corresponding Residual Certificateholder, all cash on hand from the
     Certificate Account (other than cash retained to meet claims); and the
     REMIC shall terminate at such time.

     (b) By their acceptance of the Residual Certificates, the Holders thereof
hereby (i) agree to adopt such a plan of complete liquidation of the REMIC upon
the written request of the Seller and to take such action in connection
therewith as may be reasonably requested by the Seller and (ii) appoint the
Seller as their attorney-in-fact, with full power of substitution, for purposes
of adopting such a plan of complete liquidation. The Trustee shall adopt such
plan of liquidation by filing the appropriate statement on the final tax return
of the REMIC.

     (c) At such time as each of REMIC II and REMIC III is terminated either by
a complete liquidation or upon final distribution of all of the assets of REMIC
II and REMIC III, REMIC I shall terminate.

                            Miscellaneous Provisions

     Section 11.01. INTENT OF PARTIES. The parties intend that each of the
REMICs shall be treated as a real estate mortgage investment conduit under the
Code for federal income tax purposes and that the provisions of this Agreement
should be construed in furtherance of this intent.

     Section 11.02. AMENDMENT. (a) This Agreement may be amended from time to
time by the Seller and the Trustee, and any Servicing Agreement may be amended
from time to time by the Servicer and the Trustee, without notice to or the
consent of any of the Certificateholders, to cure any ambiguity, to correct or
supplement any provisions herein that may be defective or inconsistent with any
other provisions herein, to comply with any changes in the Code or to make any
other provisions with respect to matters or questions arising under this
Agreement which shall not be inconsistent with the provisions of this Agreement;
PROVIDED, HOWEVER, that such action shall not, as evidenced by an Opinion of
Independent Counsel, adversely affect in any material respect the interests of
any Certificateholder.

     (b) This Agreement may also be amended from time to time by the Seller and
the Trustee, and any Servicing Agreement may also be amended from time to time
by the Servicer and the Trustee, with the consent of the Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than 51% of the
Trust Fund or of the applicable Class or Classes, if such amendment affects only
such Class or Classes, 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 Certificateholders; 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, (ii) reduce the aforesaid percentage of Certificates the Holders of
which are required to consent to any such amendment, without the consent of the
Holders of all Certificates then outstanding, or (iii) cause any REMIC to fail
to qualify as a REMIC for federal income tax purposes, as evidenced by an
Opinion of Independent Counsel which shall be provided to the Trustee other than
at the Trustee's expense. Notwithstanding any other provision of this Agreement,
for purposes of the giving or withholding of consents pursuant to Section
11.02(b), Certificates registered in the name of or held for the benefit of the
Seller, any Servicer, or the Trustee or any Affiliate thereof shall be entitled
to vote their Undivided Fractional Interests with respect to matters affecting
such Certificates.

     (c) Promptly after the execution of any such amendment, the Trustee shall
furnish a copy of such amendment or written notification of the substance of
such amendment to each Certificateholder, with a copy to the Rating Agencies.

     (d) In the case of an amendment under Subsection 11.02(b) above, it shall
not be necessary for the Certificateholders to approve the particular form of
such an amendment. Rather, it shall be sufficient if the Certificateholders
approve the substance of the amendment. The manner of obtaining such consents
and of evidencing the authorization of the execution thereof by
Certificateholders shall be subject to such reasonable regulations as the
Trustee may prescribe.

     (e) Prior to the execution of any amendment to this Agreement, the Trustee
shall be entitled to receive and rely upon an Opinion of Counsel stating that
the execution of such amendment is authorized or permitted by this Agreement.
The Trustee may, but shall not be obligated to, enter into any such amendment
which affects the Trustee's own rights, duties or immunities under this
Agreement.

     Section 11.03. RECORDATION OF AGREEMENT. To the extent permitted by
applicable law, this Agreement is subject to recordation in all appropriate
public offices for real property records in all the counties or other comparable
jurisdictions in which any or all of the Mortgaged Properties are situated, and
in any other appropriate public recording office or elsewhere. The Seller shall
effect such recordation, at the expense of the Trust upon the request in writing
of a Certificateholder, but only if such direction is accompanied by an Opinion
of Counsel (provided at the expense of the Certificateholder requesting
recordation) to the effect that such recordation would materially and
beneficially affect the interests of the Certificateholders or is required by
law.

     Section 11.04. LIMITATION ON RIGHTS OF Certificateholders. (a) The death or
incapacity of any Certificateholder shall not terminate this Agreement or the
Trust, nor entitle such Certificateholder's legal representatives or heirs to
claim an accounting or to take any action or proceeding in any court for a
partition or winding up of the Trust, nor otherwise affect the rights,
obligations and liabilities of the parties hereto or any of them.

     (b) Except as expressly provided in this Agreement, no Certificateholders
shall have any right to vote or in any manner otherwise control the operation
and management of the Trust, 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 establish the Certificateholders from time to time as
partners or members of an association; nor shall any Certificateholders be under
any liability to any third Person by reason of any action taken by the parties
to this Agreement pursuant to any provision hereof.

     (c) No Certificateholder shall have any right by virtue of any provision of
this Agreement to institute any suit, action or proceeding in equity or at law
upon, under or with respect to this Agreement against the Seller, any Servicer
or any successor to any such parties unless (i) such Certificateholder
previously shall have given to the Trustee a written notice of a continuing
default, as herein provided, (ii) the Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than 51% of the Trust Fund
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs and
expenses and liabilities to be incurred therein or thereby, and (iii) the
Trustee, for 60 days after its receipt of such notice, request and offer of
indemnity, shall have neglected or refused to institute any such action, suit or
proceeding.

     (d) No one or more Certificateholders shall have any right by virtue of any
provision of this Agreement to affect the rights of any other Certificateholders
or to obtain or seek to obtain priority or preference over any other such
Certificateholder, or to enforce any right under this Agreement, except in the
manner herein provided and for the equal, ratable and common benefit of all
Certificateholders. For the protection and enforcement of the provisions of this
Section 11.04, each and every Certificateholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

     Section 11.05. ACTS OF CERTIFICATEHOLDERS. (a) Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Agreement to be given or taken by Certificateholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Certificateholders in person or by an agent duly appointed in writing.
Except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is expressly required, to the Seller. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Agreement and conclusive in favor of the Trustee and the Seller,
if made in the manner provided in this Section 11.05.

     (b) The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his or her individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his or her
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the individual executing the same, may also be proved in any
other manner which the Trustee deems sufficient.

     (c) The ownership of Certificates (notwithstanding any notation of
ownership or other writing on such Certificates, except an endorsement in
accordance with Section 5.02 made on a Certificate presented in accordance with
Section 5.04) shall be proved by the Certificate Register, and neither the
Trustee, the Seller, any Servicer nor any successor to any such parties shall be
affected by any notice to the contrary.

     (d) Any request, demand, authorization, direction, notice, consent, waiver
or other action of the holder of any Certificate shall bind every future holder
of the same Certificate and the holder of every Certificate issued upon the
registration of transfer or exchange thereof, if applicable, or in lieu thereof
with respect to anything done, omitted or suffered to be done by the Trustee,
the Seller, any Servicer or any successor to any such party in reliance thereon,
whether or not notation of such action is made upon such Certificates.

     (e) In determining whether the Holders of the requisite percentage of
Certificates evidencing Fractional Undivided Interests have given any request,
demand, authorization, direction, notice, consent or waiver hereunder,
Certificates owned by the Trustee, the Seller, any Servicer or any Affiliate
thereof shall be disregarded, except as otherwise provided in Section 11.02(b)
and except that, in determining whether the Trustee shall be protected in
relying upon any such request, demand, authorization, direction, notice, consent
or waiver, only Certificates which the Trustee knows to be so owned shall be so
disregarded. Certificates which have been pledged in good faith to the Trustee,
the Seller, any Servicer or any Affiliate thereof may be regarded as outstanding
if the pledgor establishes to the satisfaction of the Trustee the pledgor's
right to act with respect to such Certificates and that the pledgor is not an
Affiliate of the Trustee, the Seller, or any Servicer, as the case may be.

     Section 11.06. GOVERNING LAW. THIS AGREEMENT AND THE CERTIFICATES SHALL BE
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REFERENCE
TO ITS CONFLICT OF LAWS RULES AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE
PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

     Section 11.07. NOTICES. All demands and notices hereunder shall be in

at the address of such Certificateholder as shown in the Certificate Register.
Any notice so mailed within the time prescribed in this Agreement shall be
conclusively presumed to have been duly given, whether or not the
Certificateholder receives such notice.

     Section 11.08. SEVERABILITY OF PROVISIONS. If any one or more of the
covenants, agreements, provisions or terms of this Agreement shall be for any
reason whatsoever held invalid, then such covenants, agreements, provisions or
terms shall be deemed severed from the remaining covenants, agreements,
provisions or terms of this Agreement and shall in no way affect the validity or
enforceability of the other provisions of this Agreement or of the Certificates
or the rights of the holders thereof.

     Section 11.09. SUCCESSORS AND ASSIGNS. The provisions of this Agreement
shall be binding upon and inure to the benefit of the respective successors and
assigns of the parties hereto.

headings herein are for convenience of reference only, and shall not limit or
otherwise affect the meaning hereof.

but all of which together shall constitute one and the same instrument.

     Section 11.12. NOTICE TO RATING AGENCIES. The article and section headings
herein are for convenience of reference only, and shall not limited or otherwise
affect the meaning hereof. The Trustee shall use its best efforts to promptly
provide notice to each Rating Agency with respect to each of the following of
which it has actual knowledge:

     1. Any material change or amendment to this Agreement or any Servicing
Agreement;

     2. The occurrence of any Event of Default that has not been cured;

     3. The resignation or termination of any Servicer or the Trustee;

     4. The repurchase or substitution of Mortgage Loans;

     This Certificate is one of a duly authorized issue of Certificates
designated as set forth on the face hereof (the "Certificates"), issued in
thirteen Classes. The Certificates, in the aggregate, evidence the entire
beneficial ownership interest in the Trust formed pursuant to the Agreement.

     The Certificateholder, by its acceptance of this Certificate, agrees that
it will look solely to the Trust for payment hereunder and that the Trustee is
not liable to the Certificateholders for any amount payable under this
Certificate or the Agreement or, except as expressly provided in the Agreement,
subject to any liability under the Agreement.

     This Certificate does not purport to summarize the Agreement and reference
is made to the Agreement for the interests, rights and limitations of rights,
benefits, obligations and duties evidenced hereby, and the rights, duties and
immunities of the Trustee.

     The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
parties thereto and the rights of the Certificateholders under the Agreement
from time to time by the parties thereto with the consent of the Holders of
Certificates evidencing Fractional Undivided Interests aggregating not less than
51% (or in certain cases, Holders of Certificates of affected Classes evidencing
such percentage of the Fractional Undivided Interests thereof). Any such consent
by the Holder of this Certificate shall be conclusive and binding on such Holder
and upon all future Holders of this Certificate and of any Certificate issued
upon the transfer hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate. The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the Holders of
any of the Certificates.

     As provided in the Agreement and subject to certain limitations therein set
forth, the transfer of this Certificate is registrable with the Trustee upon
surrender of this Certificate for registration of transfer at the offices or
agencies maintained by the Trustee in the City of New York, State of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Trustee duly executed by the Holder hereof or such Holder's
attorney duly authorized in writing, and thereupon one or more new Certificates
in authorized denominations representing a like aggregate Fractional Undivided
Interest will be issued to the designated transferee. In the case of classes of
Certificates not registered under the Securities Act of 1933, as amended,
additional documentation will be required to be provided to the Trustee prior to
the effectiveness of a transfer.

     The Certificates are issuable only as registered Certificates without
coupons in the Classes and denominations specified in the Agreement. As provided
in the Agreement and subject to certain limitations therein set forth, this
Certificate is exchangeable for one or more new Certificates evidencing the same
Class and in the same aggregate Fractional Undivided Interest, as requested by
the Holder surrendering the same.

     No service charge will be made to the Certificateholders for any such
registration of transfer, but the Trustee may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. The Trustee and any agent of any of them may treat the Person in
whose name this Certificate is registered as the owner hereof for all purposes,
and neither the Trustee nor any such agent shall be affected by notice to the
contrary.

     The obligations created by the Agreement and the Trust created thereby
(other than the obligations to make payments to Certificateholders with respect
to the termination of the Agreement) shall terminate upon the earlier of (i) the
later of the (A) final payment or other liquidation (or Monthly Advance with
respect thereto) of the last Mortgage Loan remaining in the Trust and (B)
disposition of all property acquired upon foreclosure or deed in lieu of
foreclosure of any Mortgage Loan and the remittance of all funds due under the
Agreement, or (ii) the optional repurchase by the party named in the Agreement
of all the Mortgage Loans and other assets of the Trust in accordance with the
terms of the Agreement. Such optional repurchase may be made only on or after
the Distribution Date on which the aggregate unpaid principal balance of the
Mortgage Loans is less than 10% of the aggregate Cut-off Date Scheduled
Principal Balance of the Mortgage Loans. The exercise of such right will effect
the early retirement of the related Certificates. The Trust also may be
terminated on any Distribution Date upon the determination, based upon an

         Re:      BSMSI Series 1998-5 Mortgage Pass-Through
                  Certificates (the "Certificates"),
                  including the [Class B-4, Class B-5, Class
                  B-6] CERTIFICATES (THE "PRIVATELY OFFERED
                  CERTIFICATES")

Dear Ladies and Gentlemen:

     In connection with our purchase of Privately Offered Certificates, we
confirm that:

          (i)     we understand that the Privately Offered Certificates are not
                  being registered under the Securities Act of 1933, as amended
                  (the "Act") or any applicable state securities or "Blue Sky"
                  laws, and are being sold to us in a transaction that is exempt
                  from the registration requirements of such laws;

          (ii)    any information we desired concerning the Certificates,
                  including the Privately Offered Certificates, the trust in
                  which the Certificates represent the entire beneficial
                  ownership interest (the "Trust") or any other matter we deemed
                  relevant to our decision to purchase Privately Offered
                  Certificates has been made available to us;

          (iii)   we are able to bear the economic risk of investment in
                  Privately Offered Certificates; we are an institutional
                  "accredited investor" as defined in Section 501(a) of
                  Regulation D promulgated under the Act and a sophisticated
                  institutional investor;

          (iv)    we are acquiring Privately Offered Certificates for our own
                  account, not as nominee for any other person, and not with a
                  present view to any distribution or other disposition of the
                  Privately Offered Certificates;

          (v)     we agree the Privately Offered Certificates must be held
                  indefinitely by us (and may not be sold, pledged, hypothecated
                  or in any way disposed of) unless subsequently registered
                  under the Act and any applicable state securities or "Blue
                  Sky" laws or an exemption from the registration requirements
                  of the Act and any applicable state securities or "Blue Sky"
                  laws is available;

          (vi)    we agree that in the event that at some future time we wish to
                  dispose of or exchange any of the Privately Offered
                  Certificates (such disposition or exchange not being currently
                  foreseen or contemplated), we will not transfer or exchange
                  any of the Privately Offered Certificates unless:

                    (A) (1) the sale is to an Eligible Purchaser (as defined
               below), (2) if required by the Pooling and Servicing Agreement
               (as defined below) a letter to substantially the same effect as
               either this letter or, if the Eligible Purchaser is a Qualified
               Institutional Buyer as defined under Rule 144A of the Act, the
               Rule 144A and Related Matters Certificate in the form attached to
               the Pooling and Servicing Agreement (as defined below) (or such
               other documentation as may be acceptable to the Trustee) is
               executed promptly by the purchaser and delivered to the
               addressees hereof and (3) all offers or solicitations in
               connection with the sale, whether directly or through any agent
               acting on our behalf, are limited only to Eligible Purchasers and
               are not made by means of any form of general solicitation or
               general advertising whatsoever; and

                    (B) if the Privately Offered Certificate is not registered
               under the Act (as to which we acknowledge you have no
               obligation), the Privately Offered Certificate is sold in a
               transaction that does not require registration under the Act and
               any applicable state securities or "blue sky" laws and, if
               Norwest Bank Minnesota, National Association (the "Trustee") so
               requests, a satisfactory Opinion of Counsel is furnished to such
               effect, which Opinion of Counsel shall be an expense of the
               transferor or the transferee;

          (vii)   we agree to be bound by all of the terms (including those
                  relating to restrictions on transfer) of the Pooling and
                  Servicing, pursuant to which the Trust was formed; we have
                  reviewed carefully and understand the terms of the Pooling and
                  Servicing Agreement;

          (viii)  we either: (i) are not acquiring the Privately Offered
                  Certificate directly or indirectly by, or on behalf of, an
                  employee benefit plan or other retirement arrangement which is
                  subject to Title I of the Employee Retirement Income Security
                  Act of 1974, as amended, and/or section 4975 of the Internal
                  Revenue Code of 1986, as amended, or (ii) are providing a
                  representation to the effect that the proposed transfer and/or
                  holding of a Privately Offered Certificate and the servicing,
                  management and/or operation of the Trust and its assets: (I)
                  will not result in any prohibited transaction which is not
                  covered under an individual or class prohibited transaction
                  exemption, including, but not limited to, Prohibited
                  Transaction Exemption ("PTE") 84-14, PTE 91-38, PTE 90-1, PTE
                  95-60 or PTE 96-23 and (II) will not give rise to any
                  additional fiduciary duties on the part of the either Servicer
                  or the Trustee.

          (ix)    We understand that each of the Class B-4, B-5, Class B-6
                  Certificates bears, and will continue to bear, a legend to
                  substantiate the following effect: "THIS CERTIFICATE HAS NOT

section 4975 of the Internal Revenue Code of 1986, as amended, or (ii) is
providing a representation to the effect that the proposed transfer and/or
holding of a Privately Offered Certificate and the servicing, management and/or

transaction exemption, including, but not limited to, Prohibited Transaction
Exemption ("PTE") 84-14, PTE 91-38, PTE 90-1, PTE 95-60 or PTE 96-23 and (II)
will not give rise to any additional fiduciary duties on the part of the
Servicer or the Trustee.

of a nominee on its behalf, the Purchaser has identified such nominee below, and
has caused such nominee to complete the Nominee Acknowledgment at the end of
