                     CONVEYANCE OF THE POOLED CERTIFICATES;
                        ORIGINAL ISSUANCE OF CERTIFICATES


          Section 2.01. CONVEYANCE OF THE POOLED CERTIFICATES.

          (a) The Depositor, concurrently with the execution and delivery
hereof, does hereby sell, transfer, assign, set-over and otherwise convey to the
Trustee, in trust, for the use and benefit of the Certificateholders, without
recourse, all the right, title and interest of the Depositor (i) in and to the
Pooled Certificates, (ii) in and to the Purchase Agreement and (iii) in and to
all other assets constituting the Trust Fund. Such assignment includes, without
limitation, all amounts payable on the Pooled Certificates pursuant to the
Underlying Agreements following the Closing Date or, with respect to Substitute
Pooled Certificates, following the date of substitution.

          (b) In connection with such transfer and assignment, and concurrently
with its execution and delivery of this Agreement, or, with respect to
Substitute Pooled Certificates, on the date of substitution, the Depositor shall
deliver to, and deposit with, the Trustee the Pooled Certificates together with
bond powers executed in blank or in the name of the Trustee, as trustee, except
that, with respect to any Pooled Certificates held by the Depository, the
Depositor shall have caused the Pooled Certificates to be registered in the
book-entry records of DTC in the name of the Trustee. The Depositor also shall
deposit with the Trustee no later than the Closing Date or, with respect to
Substitute Pooled Certificates, on the date of substitution, the Underlying
Agreements with respect to each Pooled Certificate and the most recent Pooled
Certificate Distribution Date Statements received by the Depositor.

          (c) The transfer of the Pooled Certificates and all other assets
constituting the Trust Fund is absolute and is intended by the parties hereto as
a sale.

          (d) It is intended that the conveyances by the Depositor to the
Trustee of the Pooled Certificates as provided for in this Section 2.01 be
construed as a sale by the Depositor to the Trustee of the Pooled Certificates
for the benefit of the Certificateholders. Further, it is not intended that any
such conveyance be deemed to be a pledge of the Pooled Certificates by the
Depositor to the Trustee to secure a debt or other obligation of the Depositor.
However, in the event that the Pooled Certificates are held to be property of
the Depositor, or if for any reason this Agreement is held or deemed to create a
security interest in the Pooled Certificates, then it is intended that (a) this
Agreement shall also be deemed to be a security agreement within the meaning of
Articles 8 and 9 of the New York Uniform Commercial Code and the Uniform
Commercial Code of any other applicable jurisdiction; (b) the conveyance
provided for in Section 2.01 shall be deemed to be a grant by the Depositor to
the Trustee of a security interest in all of the Depositor's right (including
the power to convey title thereto), title and interest, whether now owned or
hereafter acquired, in and to (1) the Pooled Certificates, (2) all amounts
payable pursuant to the Pooled Certificates in accordance with the terms thereof
and (3) any and all general intangibles consisting of, arising from or relating
to any of the foregoing, and all proceeds of the conversion, voluntary or
involuntary, of the foregoing into cash, instruments, securities or other
property, including without limitation all amounts from time to time held in the
Accounts, whether in the form of cash, instruments, securities or other
property; (c) the possession by the Trustee or any agent of the Trustee of such
items of property as constitute instruments, money, negotiable documents or
chattel paper shall be deemed to be "possession by the secured party," or
possession by a purchaser or a person designated by such secured party, for
purposes of perfecting the security interest pursuant to the New York Uniform
Commercial Code and the Uniform Commercial Code of any other applicable
jurisdiction (including, without limitation, Section 9-305, 8-313 or 8-321
thereof); and (d) notifications to persons holding such property, and
acknowledgments, receipts or confirmations from persons holding such property,
shall be deemed notifications to, or acknowledgments, receipts or confirmations
from, financial intermediaries, bailees or agents (as applicable) of the Trustee
for the purpose of perfecting such security interest under applicable law.

          The Depositor and the Trustee, at the direction of the Depositor or
the Majority Certificateholders, shall, to the extent consistent with this
Agreement, take such reasonable actions as may be determined to be necessary to
ensure that, if this Agreement were deemed to create a security interest in the
Pooled Certificates, and the other property described above, such security
interest would be deemed to be a perfected security interest of first priority
under applicable law and will be maintained as such throughout the term of this
Agreement.

          Section 2.02. ACCEPTANCE OF TRUST FUND BY TRUSTEE; INITIAL
                        ISSUANCE OF CERTIFICATES.

          The Trustee acknowledges (i) receipt of the Underlying Agreements and
the most recent Pooled Certificate Distribution Date Statements, (ii) the
receipt by it and the transfer, delivery and assignment to it of the Pooled
Certificates, in good faith and without notice of any adverse claim, (iii) the
receipt by it of $20,000 for deposit in the Prepayment Interest Shortfall
Account, $2,613 for deposit in the Interest Account, $65,000 for deposit in the
Trustee Fee Account and $100.54 for deposit into the subaccount of the
Certificate Account relating to the Class R Certificates, and the assignment to
it of all other assets included in the Trust Fund and declares that it holds and
will hold the Pooled Certificates and all other assets included in the Trust
Fund in trust for the exclusive use and benefit of all present and future
Certificateholders (except also for its benefit in the case of the Trustee Fee
Account) in accordance with the terms of this Agreement. Concurrently with such
transfer, delivery and assignment and in exchange therefor, pursuant to the
written request of the Depositor executed by an officer of the Depositor, the
Trustee has executed and caused to be authenticated and delivered to or upon the
order of the Depositor, the Certificates in authorized denominations evidencing
the entire beneficial ownership of the Trust Fund.

          The Trustee shall, within three Business Days of the Closing Date or,
with respect to Substitute Pooled Certificates, within three Business Days of
the date of substitution, deliver to the applicable trustee for reregistration
in the name of the Trustee, as trustee hereunder each Pooled Certificate
delivered to it in physical form along with the related bond power received from
the Depositor.

          Until the Trust Fund is terminated in accordance with Section 7.01,
except as provided herein, the Trustee shall not assign, sell, dispose of or
transfer any interest in the Pooled Certificates or any other asset constituting
the Trust Fund or permit the Pooled Certificates or any other asset constituting
the Trust Fund to be subjected to any lien, claim or encumbrance arising by,
through or under the Trustee or any person claiming by, through or under the
Trustee.

          Section 2.03. REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR
                        AND THE TRUSTEE.

          (a) The Depositor hereby represents and warrants to the Trustee and
for the benefit of the Certificateholders, as of the Closing Date and with
respect to any Substitute Pooled Certificate, as of the related date of
substitution, that:

               (i) The Depositor is a corporation duly organized, validly
          existing and in good standing under the laws of the State of Delaware,
          and the Depositor is possessed of all licenses necessary to carry on
          its business.

               (ii) The execution and delivery of this Agreement by the
          Depositor, and the performance and compliance with the terms of this
          Agreement by the Depositor, will not violate the Depositor's
          certificate of incorporation or bylaws or constitute a default (or an
          event which, with notice or lapse of time, or both, would constitute a
          default) under, or result in the breach of, any material agreement or
          other instrument to which it is a party or which is applicable to it
          or any of its assets.

               (iii) The Depositor has the full right, power and authority to
          enter into and consummate all transactions contemplated by this
          Agreement, including but not limited to selling the Pooled
          Certificates to the Trustee, has duly authorized the execution,
          delivery and performance of this Agreement, and has duly executed and
          delivered this Agreement.

               (iv) This Agreement, assuming due authorization, execution and
          delivery by the Trustee, constitutes a valid, legal and binding
          obligation of the Depositor, enforceable against the Depositor in
          accordance with the terms hereof, subject to (A) applicable
          bankruptcy, insolvency, reorganization, moratorium and other laws
          affecting the enforcement of creditors' rights generally, and (B)
          general principles of equity, regardless of whether such enforcement
          is considered in a proceeding in equity or at law.

               (v) The Depositor is not in violation of, and its execution and
          delivery of this Agreement and its performance and compliance with the
          terms of this Agreement will not constitute a violation of, any law,
          any order or decree of any court or arbiter, or any order, regulation
          or demand of any federal, state or local governmental or regulatory
          authority, which violation is likely to affect materially and
          adversely either the ability of the Depositor to perform its
          obligations under this Agreement or the financial condition of the
          Depositor.

               (vi) No litigation is pending or, to the best of the Depositor's
          knowledge, threatened against the Depositor which, if determined
          adversely to the Depositor, would prohibit the Depositor from entering
          into this Agreement or is likely to materially and adversely affect
          either the ability of the Depositor to perform its obligations under
          this Agreement or the financial condition of the Depositor.

               (vii) The Depositor was, immediately prior to the transfer of the
          Pooled Certificates to the Trustee, the sole owner thereof free and
          clear of any lien, pledge, charge or encumbrance of any kind (except
          any lien created by this Agreement).

               (viii) The Depositor acquired the Pooled Certificates in good
          faith without notice of any adverse claim, lien, charge, encumbrance
          or security interest (including without limitation, federal tax liens
          or liens arising under ERISA).

               (ix) The Depositor has not assigned any interest in the Pooled
          Certificates or any distributions thereon, except as contemplated
          herein.

               (x) The Trustee, in its capacity as a Pooled Certificateholder,
          will be entitled to distributions under the Underlying Agreements
          equal to all distributions of interest and principal made on the
          Pooled Certificates.

               (xi) As of the Closing Date, each Pooled Certificate Group has an
          aggregate principal balance greater than or equal to the Original
          Class Balance of the Class of Certificates with the same alpha-numeric
          designation.

               (xii) The information relating to the each Pooled Certificate
          Group set forth in Schedule A is true and correct in all material
          respects.

               (xiii) Each Pooled Certificate is either a Certificated Security
          (as such term is defined in Article 8 of the Uniform Commercial Code),
          in the possession of the Trustee together with bond powers executed in
          blank or to the Trustee signed by an appropriate person or an
          Uncertificated Security (as such term is defined in Article 8 of the
          Uniform Commercial Code) registered on the books of DTC in the name of
          the Trustee or its financial intermediary on behalf of the Trustee.

               (xiv) The Pooled Certificates were structured to be REMIC regular
          interests under the REMIC Provisions;

               (xv) The Depositor has no actual knowledge that (a) each trust
          issuing each Pooled Certificate was not duly created and is not
          validly existing and (b) each Pooled Certificate (1) was not validly
          issued by such trust and (2) is not outstanding, (3) is not the legal,
          valid, binding and enforceable obligation of such trust and (4) is not
          entitled to the benefits of the pooling and servicing agreement, trust
          agreement or other document pursuant to which such Pooled Certificate
          was issued (except as limited by bankruptcy, insolvency or other
          similar laws affecting the enforcement of creditors' rights generally
          or to the extent that such enforceability may be subject to the
          exercise of judicial discretion in accordance with general equitable
          principles).

               (xvi) The Depositor has no actual knowledge that each trust or
          other issuer issuing Pooled Certificates does not own all right, title
          and interest in and to the Underlying Mortgage Loans and other
          property constituting the trust estate of such trust, free and clear
          of any claim, lien, charge, security interest or other encumbrance
          (except the lien of the applicable pooling and servicing agreement,
          trust agreement or other document pursuant to which each Pooled
          Certificate was issued), or that such Underlying Mortgage Loans and
          other property would constitute property of any entity transferring
          the same to the trust in the event any such transferring entity became
          subject to proceedings under Section 541 of the United States
          Bankruptcy Code, 11 U.S.C. Sec. 101 et seq., as amended (the
          "Bankruptcy Code"), and accordingly, payments on the Underlying
          Mortgage Loans would be subject to the automatic stay of Section 362
          of the Bankruptcy Code.

               (xvii) The Depositor has no actual knowledge that any pooling and
          servicing agreement, trust agreement or other document pursuant to
          which each Pooled Security was issued was required to be registered or
          qualified under the Trust Indenture Act of 1939, as amended, and no
          trust or other issuer issuing Pooled Certificates was required to be
          registered as an investment company under the Investment Company Act
          of 1940, as amended.

          (b) The Trustee hereby represents and warrants to the Depositor and
for the benefit of the Certificateholders, as of the Closing Date, that:

               (i) The Trustee is a national banking association, duly organized
          and validly existing under the laws of the United States of America.

               (ii) The execution and delivery of this Agreement by the Trustee,
          and the performance and compliance with the terms of this Agreement by
          the Trustee, will not violate the Trustee's charter or bylaws or
          constitute a default (or an event which, with notice or lapse of time,
          or both, would constitute a default) under, or result in the breach
          of, any material agreement or other instrument to which it is a party
          or which is applicable to it or any of its assets.

               (iii) The Trustee has the full power and authority to enter into
          and consummate all transactions contemplated by this Agreement, has
          duly authorized the execution, delivery and performance of this
          Agreement, and has duly executed and delivered this Agreement.

               (iv) This Agreement, assuming due authorization, execution and
          delivery by the Depositor, constitutes a valid, legal and binding
          obligation of the Trustee, enforceable against the Trustee in
          accordance with the terms hereof, subject to (A) applicable
          bankruptcy, insolvency, reorganization, moratorium and other laws
          affecting the enforcement of creditors' rights generally, and (B)
          general principles of equity, regardless of whether such enforcement
          is considered in a proceeding in equity or at law.

               (v) The Trustee is not in violation of, and its execution and
          delivery of this Agreement and its performance and compliance with the
          terms of this Agreement will not constitute a violation of, any law,
          any order or decree of any court or arbiter, or any order, regulation
          or demand of any federal, state or local governmental or regulatory
          authority, which violation is likely to affect materially and
          adversely either the ability of the Trustee to perform its obligations
          under this Agreement or the financial condition of the Trustee.

               (vi) No litigation is pending or, to the best of the Trustee's
          knowledge, threatened against the Trustee which would prohibit the
          Trustee from entering into this Agreement or is likely to materially
          and adversely affect either the ability of the Trustee to perform its
          obligations under this Agreement or the financial condition of the
          Trustee.

               (vii) The Pooled Certificates will be registered in the name of
          the Trustee; the information relating to the Pooled Certificates set
          forth on Schedule A hereto conforms to information set forth on the
          face of the Pooled Certificates and the most recent Pooled Certificate
          Distribution Date Statements, as applicable; it has acquired the
          Pooled Certificates on behalf of the Certificateholders from the
          Depositor in good faith, for value, and, to the best of the Trustee's
          knowledge, without notice or actual knowledge of any adverse claim,
          lien, charge, encumbrance or security interest (including, without
          limitation, federal tax liens or liens arising under ERISA); it has
          not and will not, in any capacity, assert any claim or interest in the
          Pooled Certificates and will hold such Pooled Certificates and the
          proceeds thereof in trust pursuant to the terms of this Agreement; and
          it has not encumbered or transferred its right, title or interest in
          the Pooled Certificates.

          (c) It is understood and agreed that the foregoing representations and
warranties shall survive the execution and delivery of this Agreement. Upon
discovery by either party hereto of a breach of any of the foregoing
representations and warranties which materially and adversely affects the
interests of the Certificateholders or either party hereto, the party
discovering such breach will give prompt written notice thereof to the other
party hereto and to the Certificateholders. Within thirty (30) days of the
earlier of either discovery by or notice to the Depositor of any breach of a
representation or warranty of the Depositor that materially and adversely
affects the interests of the Certificateholders, the Depositor shall use its
best efforts promptly to cure such breach in all material respects and, if such
breach cannot be cured, the Depositor shall, at the election of the Majority
Class Certificateholders of the related Class, repurchase each Pooled
Certificate affected by the breach, as well as all of the Pooled Certificates
within the same Pooled Certificate Group as the Pooled Certificate with respect
to which a breach has occurred, at the Repurchase Price provided that if the
Majority Class Certificateholders of the related Class exercise the foregoing
election, the Depositor shall alternatively at its option substitute one or more
Substitute Pooled Certificates for the Pooled Certificate affected by the breach
pursuant to Section 2.04, as well as all of the Pooled Certificates within the
same Pooled Certificate Group as the Pooled Certificate with respect to which a
breach has occurred. If the Depositor is to repurchase Pooled Certificates, the
Trustee shall promptly determine the Repurchase Price in accordance with the
definition thereof. Repurchase of any of the Pooled Certificates pursuant to the
foregoing provisions of this Section 2.03(c) shall be accomplished by (i)
deposit in the Certificate Account on the Business Day prior to the next
succeeding Distribution Date of the amount of the Repurchase Price and (ii)
amending Schedule A hereto to remove the related Deleted Pooled Certificates.

          Section 2.04. SUBSTITUTION OF POOLED CERTIFICATES. Notwithstanding
anything to the contrary in this Agreement, in lieu of repurchasing a Pooled
Certificate pursuant to Section 2.03(c), the Depositor may, no later than the
date by which such repurchase by the Depositor would otherwise be required,
tender to the Trustee one or more Substitute Pooled Certificates accompanied by
an Officer's Certificate of the Depositor that each of such Substitute Pooled
Certificates conforms to the requirements set forth in the definition of
"Substitute Pooled Certificate;" provided, however, that substitution pursuant
to this Section 2.04 in lieu of repurchase shall not be permitted after the
termination of the two-year period beginning on the Closing Date. The Trustee
shall accept any such Substitute Pooled Certificate, which shall thereafter be
deemed to be a Pooled Certificate hereunder. In the event of such a
substitution, payments received on the Substitute Pooled Certificate for the
month in which the substitution occurs shall be the property of the Depositor
and payments received on the Deleted Pooled Certificates during such month shall
be the property of the Trust Fund. Upon acceptance of any Substitute Pooled
Certificate, the Trustee shall release to the Depositor 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 the Depositor title to and rights
under the related Deleted Pooled Certificate released pursuant to this Section
2.04. The Depositor shall deliver the documents related to any Substitute Pooled
Certificate in accordance with the provisions of Section 2.01. The
representations and warranties set forth in 2.03(a) concerning the Pooled
Certificates shall be deemed to have been made by the Depositor with respect to
each Substitute Pooled Certificate as of the date of acceptance of such
Substitute Pooled Certificate by the Trustee. On or prior to the date of
substitution, the Trustee shall amend Schedule A hereto, to reflect such
substitution and shall provide a copy of such amended Schedule to the Depositor
and the Rating Agencies.

                   ADMINISTRATION OF THE POOLED CERTIFICATES;
                   PAYMENTS AND REPORTS TO CERTIFICATEHOLDERS


          Section 3.01. ADMINISTRATION OF THE TRUST FUND AND
                        THE POOLED CERTIFICATES.

          (a) If at any time the Trustee, as a holder of a Pooled Certificate,
is requested in such capacity, whether by a Certificateholder, a holder of a
certificate of an Underlying Series or a party to the related Underlying
Agreement or any other Person, to take any action or to give any consent,
approval or waiver, including without limitation in connection with the
servicing and administration of Acquired Mortgage Assets, an amendment of any
Underlying Agreement or the occurrence of an Underlying Event of Default, the
Trustee shall promptly notify the Depositor and all of the holders of the Class
or Classes of Certificates with the same alpha-numeric designation as the Pooled
Certificate Group or Pooled Certificate Groups, which contain the Pooled
Certificate as to which action is requested, of such request and of its planned
course of action with respect thereto and shall, in its capacity as a holder of
Pooled Certificates, take such action in connection with the exercise and/or
enforcement of any rights and/or remedies available to it in such capacity with
respect to such request as the Majority Class Certificateholders of the affected
Class or Classes shall direct in writing. The Trustee shall promptly furnish to
the Depositor and, upon the written request of a Certificateholder, such
Certificateholder, all notices, statements, reports or other information that it
receives as holder of the Pooled Certificates, including without limitation
information regarding the Underlying Mortgage Loans and any Acquired Mortgage
Assets.

          Section 3.02. COLLECTION OF MONIES.

          (a) In connection with its receipt of any distribution on the Pooled
Certificates on any Pooled Certificate Distribution Date (or such later date on
which the Trustee shall receive the related Pooled Certificate Distribution Date
Statement), the Trustee shall review each related Pooled Certificate
Distribution Date Statement delivered to it and shall confirm that the aggregate
amount of such distribution received is consistent with the information
contained therein (it being understood that the Trustee shall be entitled to
rely on the accuracy and correctness of the information set forth on such
statements).

          If the Trustee shall gain actual knowledge of any Underlying Event of
Default, the Trustee shall promptly notify the Certificateholders and the
Depositor of such occurrence and such parties shall proceed in accordance with
the terms and conditions of Section 3.01.

          (b) If the Trustee receives a Notice of Final Distribution in respect
of any of the Pooled Certificates, the Trustee shall present and surrender any
related Pooled Certificates which are in certificated form for final payment
thereon in accordance with the terms and conditions of the related Underlying
Agreement and such notice. The Trustee shall promptly deposit in the Certificate
Account the final distribution received upon presentation and surrender of such
Pooled Certificates for distribution in accordance with Section 3.05 hereof on
the next succeeding Distribution Date.

          Section 3.03. ESTABLISHMENT OF THE ACCOUNTS; DEPOSITS THEREIN.

          (a) The Trustee, for the benefit of the Certificateholders, shall
establish and maintain one or more interest bearing accounts (collectively, the
"Certificate Account"), each of which shall be an Eligible Account, entitled
"First Trust National Association, as trustee for the registered holders of Bear
Stearns Mortgage Securities Inc. Trust Certificates, Series 1997-2," held in
trust by the Trustee for the benefit of the Certificateholders. The Certificate
Account shall have one subaccount for all funds collected with respect to each
Pooled Certificate Group and one subaccount relating to the Class R
Certificates, into which $100 plus one month's interest at 6.500% thereon will
be deposited on the Closing Date. The Trustee shall cause all distributions
received on the Pooled Certificates of each Pooled Certificate Group by the
Trustee in its capacity as holder of the Pooled Certificates, from whatever
source, and all amounts received by it representing payment of a Repurchase
Price pursuant to Section 2.03(c), subsequent to the Closing Date to be
deposited directly into the applicable subaccount of the Certificate Account. On
each Distribution Date the Trustee also shall deposit from the Prepayment
Interest Shortfall Account into the applicable subaccount of the Certificate
Account funds with respect to any Prepayment Interest Shortfalls on the related
Pooled Certificate Group, to the extent required by Section 3.03(d). On each
Distribution Date on which the Class A-1, Class A-3 and/or Class A-5
Certificates are outstanding, the Trustee shall additionally deposit from the
Interest Account into the applicable subaccount of the Certificate Account funds
to the extent of the Class Interest Shortfall on the applicable Class of
Certificates pursuant to Section 3.03(c). The Certificate Account is initially
located at the Trustee. The Trustee shall give notice to the Depositor and to
Certificateholders of any new location of the Certificate Account prior to any
change thereof.

          (b) In the event that payments in respect of the Pooled Certificates
are received by the Trustee prior to the related Distribution Date, the Trustee
may invest such funds deposited in the Certificate Account in one or more
Permitted Investments held in the name of the Trustee and shall receive as
compensation, in addition to the Trustee Fee, any interest or investment income
earned on such Permitted Investments, which may be withdrawn by the Trustee on
each Distribution Date and shall not constitute Available Funds. Notwithstanding
the foregoing, no such Permitted Investment may mature later than the day before
such related Distribution Date and no such investment shall be sold prior to its
maturity date. The amount of any net losses incurred in respect of any such
investments shall be deposited in the Certificate Account by the Trustee out of
its own funds immediately as realized.

          (c) The Trustee, for the benefit of the Class A-1, Class A-3 and Class
A-5 Certificateholders, shall establish and maintain one or more interest
bearing accounts (collectively, the "Interest Account"), each of which shall be
an Eligible Account, entitled "First Trust National Association, as trustee for
the registered holders of Bear Stearns Mortgage Securities Inc. Trust
Certificates, Series 1997-2, Class A-1, Class A-3 and Class A-5 held in trust
(but outside of the REMIC Trust) by the Trustee for the benefit of the Class
A-1, Class A-3 and Class A-5 Certificateholders. Funds in the Interest Account
shall not be invested. The Interest Account is initially located at the Trustee.
The Trustee shall give notice to the Depositor and the Class A-1, Class A-3 and
Class A-5 Certificateholders of any new location of the Interest Account prior
to any change thereof. On the Closing Date, the Depositor shall provide to the
Trustee for deposit in the Interest Account $2,613. On each Distribution Date,
the Trustee shall transfer from the Interest Account to the applicable
subaccount of the Certificate Account an amount necessary to cover the
applicable Class Interest Shortfall. Any funds remaining in such Interest
Account after the Class A-1, A-3 and Class A-5 Certificates have been paid in
full shall be transferred to the Prepayment Interest Shortfall Account.

          (d) The Trustee, for the benefit of the Certificateholders, shall
establish and maintain one or more interest bearing accounts (collectively, the
"Prepayment Interest Shortfall Account"), each of which shall be an Eligible
Account, entitled "First Trust National Association, as trustee for the
registered holders of Bear Stearns Mortgage Securities Inc. Trust Certificates,
Series 1997-2", held in trust (but outside of the REMIC Trust) by the Trustee
for the benefit of the Certificateholders of all Classes. The Prepayment
Interest Shortfall Account is initially located at the Trustee. The Trustee
shall give notice to the Depositor and the Certificateholders of any new
location of the Prepayment Interest Shortfall Account prior to any change
thereof. On the Closing Date, the Depositor shall provide to the Trustee for
deposit in the Prepayment Interest Shortfall Account $20,000. Following each
Determination Time, the Trustee will determine if there is any Prepayment
Interest Shortfall with respect to a Pooled Certificate Group. If such
Prepayment Interest Shortfall has been allocated to Pooled Certificates in one
or more Pooled Certificate Groups, the Trustee will withdraw the lesser of the
aggregate amount thereof and the amount then remaining in the Prepayment
Interest Shortfall Account for deposit in the applicable subaccount or
subaccounts of the Certificate Account. If there is an insufficient amount on
deposit in the Prepayment Interest Shortfall Account, the amount thereof will be
allocated among such subaccounts based upon the amount of Prepayment Interest
Shortfall allocated to the related Pooled Certificate Groups.

          (e) The Trustee shall establish and maintain one or more interest
bearing accounts (collectively, the "Trustee Fee Account"), each of which shall
be an Eligible Account, held in trust by the Trustee for the benefit of the
Certificateholders and the Trustee, entitled "First Trust National Association,
as trustee for the registered holders of Bear Stearns Mortgage Securities Inc.
Trust Certificates, Series 1997-2." The Trustee Fee Account is initially located
at the Trustee. The Trustee shall give notice to the Depositor and the
Certificateholders of any new location of the Trustee Fee Account prior to any
change thereof. On the Closing Date the Depositor shall provide to the Trustee
for deposit in the Trustee Fee Account $65,000. On each Distribution Date the
Trustee may withdraw as its fee from the Trustee Fee Account $_193.45, together
with all investment earnings on amounts in the Trustee Fee Account as of each
such date of withdrawal. The Trustee shall invest any amounts deposited in the
Trustee Fee Account in one or more Permitted Investments provided that
sufficient funds shall be available to pay the $193.45 on each Distribution
Date. The amount of any net losses incurred in respect of any investment shall
be deposited in the Trustee Fee Account by the Trustee out of its own funds
immediately as realized. If the Trustee resigns or is removed and a successor
trustee is appointed, any amounts on deposit in the Trustee Fee Account shall
thereafter be held in the same manner by and for the benefit of the successor
trustee. Upon the termination of the Trust Fund, any amount (including earnings)
remaining in the Trustee Fee Account shall be paid to the Trustee.

          (f) With respect to each 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. 92a(e), if applicable, or any applicable comparable state statute
applicable to state chartered banking corporations.

          Section 3.04. PERMITTED WITHDRAWALS FROM THE CERTIFICATE ACCOUNT.

          The Trustee may from time to time withdraw funds from the Certificate
Account for the following purposes:

               (i) to make distributions in the amounts and in the manner
          provided for in Section 3.05;

               (ii) to pay to the Person entitled thereto any amount deposited
          in the Certificate Account in error;

               (iii) to clear and terminate the Certificate Account upon the
          termination of this Agreement; and

               (iv) to pay itself, as additional compensation, the net
          reinvestment income permitted to be paid to it as provided in Section
          3.03(b).

          On each Distribution Date, the Trustee shall withdraw all funds from
the Certificate Account and shall use such funds withdrawn from the Certificate
Account only for the purposes described in this Section 3.04 and in Section
3.05.

          Section 3.05. DISTRIBUTIONS.

          (a) On each Distribution Date, the Trustee shall apply the Available
Funds on deposit in each subaccount of the Certificate Account as of such
Distribution Date in the following manner and order of priority, except that on
the first Distribution Date all amounts in the subaccount of the Certificate
Account relating to the Class R Certificates (other than investment income)
shall be first paid to the Holders of the Class R Certificates:

               (A)  from amounts with respect to interest received on the Pooled
                    Certificates of a Pooled Certificate Group and from any
                    transfers from the Prepayment Interest Shortfall Account and
                    the Interest Account, to the Certificateholders of the Class
                    with the same alpha-numeric designation as distributions of
                    interest, an amount equal to interest for such Class accrued
                    at the applicable per annum Pass-Through Rate during the
                    Interest Accrual Period preceding such Distribution Date on
                    its Class Balance immediately prior to such Distribution
                    Date, less the sum of any Prepayment Interest Shortfalls to
                    the extent not covered by funds transferred from the
                    Prepayment Interest Shortfall Account and the interest
                    portion of any losses allocated to the Pooled Certificates
                    in the related Pooled Certificate Group, plus the portion,
                    if any, of interest accrued for such Class for any prior
                    Distribution Date which remains unpaid;

               (B)  from amounts with respect to principal received on the
                    Pooled Certificates of such Pooled Certificate Group, to the
                    Certificateholders of the Class with the same alpha-numeric
                    designation as distributions of principal, an amount equal
                    to such principal received; and

               (C)  on each Distribution Date on which a Class of Certificates,
                    other than the Class R Certificates, is paid in full,
                    Available Funds, if any, remaining in the related subaccount
                    of the Certificate Account (other than investment income)
                    after payment of interest and principal, as described above
                    to Certificateholders of such Class will be distributed to
                    the Class R Certificates.

          If the Trustee has not received a distribution on, or the Pooled
Certificate Distribution Date Statement with respect to, the Pooled Certificates
of a Pooled Certificate Group by the Determination Time, the distribution
allocable to the related Class of Certificates will not be made on the
immediately following Distribution Date, but, (i) if such distribution and such
Pooled Certificate Distribution Date Statement are received by 3:00 p.m. on the
fifth Business Day after the Determination Time, the Trustee will make the
distribution on the sixth Business Day after the Determination Time (a
"Supplemental Distribution Date") or (ii) if received after 3:00 p.m. on the
fifth Business Day after the Determination Time, it will be made on the next
succeeding Distribution Date, and in neither case will additional interest be
paid thereon.

          (b) All distributions made to Certificateholders of a Class pursuant
to Section 3.05(a) on each Distribution Date or on a Supplemental Distribution
Date shall be allocated pro rata among the outstanding Certificates of such
Class based upon their respective Percentage Interests and, except in the case
of the final distribution to the Certificateholders, shall be made to the
Holders of record on the related Record Date. Distributions to any
Certificateholder on any Distribution Date shall be made by wire transfer of
immediately available funds to the account of such Certificateholder at a bank
or other entity having appropriate facilities therefor, if such
Certificateholder shall have so notified the Trustee in writing (which wiring
instructions may be in the form of a standing order applicable to all future
Distribution Dates) no less than five Business Days prior to the related Record
Date (or, in the case of the initial Distribution Date, no later than the
related Record Date) and is the registered owner of Certificates with an
aggregate initial Certificate Balance of not less than $1,000,000, or otherwise
by check mailed by first class mail to the address of such Certificateholder
appearing in the Certificate Register. Final distribution to each
Certificateholder will be made in like manner, but only upon presentment and
surrender of such Certificate at the Corporate Trust Office or such other
location specified in the notice to Certificateholders of such final
distribution.

          (c) Notwithstanding any other provision of this Agreement, the Trustee
shall comply with all federal withholding requirements respecting payments to
Certificateholders of interest or the accrual of original issue discount that
the Trustee reasonably believes are applicable under the Code. The consent of
Certificateholders shall not be required for such withholding. In the event the
Trustee does withhold any amount from payments to any Certificateholder pursuant
to federal withholding requirements, the Trustee shall indicate the amount
withheld to such Certificateholders.

          (d) The Trustee may conclusively rely on the information set forth in
the Pooled Certificate Distribution Date Statements in making the calculations
called for in this Section 3.05, including, without limitation, the
determinations of the interest and principal to be paid on each Class of
Certificates. If the information available to the Trustee in any Pooled
Certificate Distribution Date Statement is insufficient to make the calculations
provided for in this Section 3.05, the Trustee shall promptly request the
underlying trustee with respect to the Pooled Certificates to provide sufficient
information in writing, and after receipt of such information the Trustee shall
make on the following Distribution Date any necessary adjustments in the
application of amounts in the applicable subaccount of the Certificate Account.
If such information is not received from such underlying trustee, the Trustee
shall not be responsible for making any such adjustment.

          Section 3.06. STATEMENTS TO CERTIFICATEHOLDERS.

          On each Distribution Date, the Trustee shall prepare, and shall
forward by mail, a statement to each Certificateholder, the Depositor and the
Rating Agency stating:

               (i) the Available Funds for each Class of Certificates for such
          Distribution Date;

               (ii) the amount of interest and principal being distributed on
          each Class of Certificates for such Distribution Date, separately
          stating the amount of interest provided from the Prepayment Interest
          Shortfall Account;

               (iii) the Class Balances for each Class of Certificates before
          and after applying payments on such Distribution Date;

               (iv) the remaining amount in the Prepayment Interest Shortfall
          Account following the payment on such Distribution Date;

               (v) the outstanding principal amount immediately prior to and
          after taking into account distributions made on the immediately prior
          Pooled Certificate Distribution Date, and the current interest rate
          and current realized losses allocated to, each of the Pooled
          Certificates in each Pooled Certificate Group on the immediately prior
          Pooled Certificate Distribution Date; and

               (vi) any amount in the Trustee Fee Account applied to pay the
          Trustee Fee and the balance of the Trustee Fee Account as of such
          Distribution Date.

          In the case of the information furnished pursuant to clauses (ii) and
(iii) above, the amounts shall also be expressed as a dollar amount per Single
Certificate. The Trustee's responsibility for reporting the above information is
limited to the availability, timeliness, and accuracy of the information set
forth in the related Pooled Certificate Distribution Date Statements and any
additional written information requested by the Trustee with respect to the
Pooled Certificates. If the Trustee receives any such additional information
after preparing a statement required by this Section, the Trustee shall report
the related adjustments in the statement prepared after receipt of such
information.

          In addition, the Trustee promptly will furnish to the Depositor and,
upon the written request of a Certificateholder, to such Certificateholder,
copies of any notices, statements, reports or other communications including,
without limitation, the Pooled Certificate Distribution Date Statement, received
by the Trustee in its capacity as a holder of Pooled Certificates, with respect
to the Pooled Certificates related to the Certificates held by such
Certificateholder. The Trustee shall furnish copies of all Pooled Certificate
Distribution Date Statements to the Rating Agency promptly after its receipt of
same. The Trustee may fulfill its obligations hereunder with respect to the
distribution of the Pooled Certificate Distribution Date Statements by mailing
the same together with the statements to Certificateholders required pursuant to
the first paragraph of this Section 3.06.

          On or before March 31st of each calendar year, commencing in 1998, the
Trustee shall prepare and deliver by first class mail to the Depositor and to
each Person who at any time during the prior calendar year was a
Certificateholder of record a statement containing the information required to
be contained in the regular monthly report to Certificateholders, as set forth
in clauses (ii) above aggregated for such prior calendar year or in the case of
a Certificateholder, the applicable portion thereof during which such Person was
a Certificateholder. Such obligation of the Trustee shall be deemed to have been
satisfied to the extent that substantially comparable information shall be
provided by the Trustee pursuant to any requirements of the Code and regulations
thereunder as from time to time are in force.

          The Trustee shall be responsible for preparing, at its own expense,
signing and filing, on behalf of the Trust Fund, federal income tax and
information returns with the Internal Revenue Service ("IRS") and Minnesota
income tax returns and/or the returns of any other state taxing authority the
necessity of filing of which shall have been confirmed to the Trustee in writing
either by the delivery of an Opinion of Counsel to such effect or by the
delivery to the Trustee of a written notification to such effect by the taxing
authority of any such state. The Depositor shall provide the Trustee within 10
days of the Closing Date all information deemed necessary by the Trustee to
fulfill its obligations under this paragraph. The Trustee shall furnish to each
Certificateholder at the time required by law such information reports or
returns as are required by applicable federal, state or local law with respect
to the Trust Fund to enable Certificateholders to prepare their tax returns and
will furnish comparable information to the IRS and other taxing authorities as
and when required by law to do so.

          Section 3.07. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION.

          The Trustee shall provide to the Depositor access to all reports,
documents and records maintained by the Trustee in respect of its duties
hereunder, such access being afforded without charge but only upon three
Business Days' written request and during normal business hours at offices
designated by the Trustee.

          Section 3.08. CALCULATION OF AMOUNTS TO BE DISTRIBUTED.

          All calculations of the amounts to be distributed on any Distribution
Date and of the amount of any transfers from the Prepayment Interest Shortfall
Account or the Interest Account to the applicable subaccount or subaccounts of
the Certificate Account will be made by the Trustee in reliance on the
information provided to it in the applicable Pooled Certificate Distribution
Date Statements and any additional written information requested by the Trustee
with respect to the Pooled Certificates. The Trustee shall promptly communicate
the results of its calculations to the Depositor and the Certificateholders
(which obligation may be satisfied through the distribution of the statements
required under Section 3.06).

          Section 3.09. REMIC-RELATED COVENANTS. For as long as REMIC Trust
shall exist, the Trustee shall act in accordance herewith to assure continuing
treatment of the REMIC Trust as a REMIC. In particular, the Trustee shall not
other than with respect to a substitution pursuant to Section 2.04, accept any
contribution to the REMIC Trust after the Startup Day without receipt of a REMIC
Opinion.

                                   ARTICLE IV

                                THE CERTIFICATES

          Section 4.01. THE CERTIFICATES.

          (a) The Depository, the Depositor and the Trustee have entered into a
Depository Agreement dated as of March 27, 1997 (the "Depository Agreement").
Except with respect to the Class R Certificates and as provided in Subsection
4.01(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 the Certificate Owners 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.

          Except, with respect to the Class R Certificates, all transfers by
Certificate Owners of 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 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 Depositor 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 Depositor is unable to
locate a qualified successor within 30 days or (ii) the Depositor 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 (the "Definitive 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 Depositor 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) The Classes of Certificates shall have the following designations,
initial principal amounts and Pass- Through Rates:

                             Initial             Pass-Through
    Designations        Principal Amounts          Rate
    ------------        -----------------          ----
         A-1              $16,125,845              6.750%
         A-2              $16,629,916              6.500%
         A-3              $17,681,374              6.750%
         A-4              $16,668,278              6.500%
         A-5              $15,195,964              6.875%
          R                      $100              6.500%


          (d) 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 based upon the respective Pass-Through Rate set forth above and the
Class Balance of such Class applicable to such Distribution Date.

          (e) The Certificates shall be substantially in the forms set forth in
Exhibit A through Exhibit F hereto. The Certificates shall be executed by manual
signature on behalf of the Trustee in its capacity as trustee hereunder by an
authorized officer. Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Trustee shall be
entitled to all benefits under this Agreement, subject to the following
sentence, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Certificates
or did not hold such offices at the date of such Certificates. No Certificate
shall be entitled to any benefit under this Agreement, or be valid for any
purpose, unless there appears on such Certificate a certificate of
authentication substantially in the form provided for herein executed by the
Certificate Registrar by manual signature, and such certificate upon any
Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication. The Class R
Certificates shall be issued in fully-registered form in the denomination of
$100.00 each.

          Pending the preparation of Definitive Certificates, the Trustee may
sign and the Certificate Registrar may authenticate temporary Certificates that
are printed, lithographed or typewritten, in authorized denominations for
Certificates, 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 Depositor 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 the Certificate Registrar shall authenticate and deliver
in exchange therefor a like aggregate principal amount, in authorized
denominations, of Definitive Certificates. Until so exchanged, such temporary
Certificates shall in all respects be entitled to the same benefits as
Definitive Certificates.

          (f) Each Class of Certificates, except the Class R Certificates, will
be registered as a single Certificate held by a nominee of the Depository, and
beneficial interests will be held by investors through the book-entry facilities
of the Depository in minimum denominations of $25,000 and increments of $1 in
excess thereof, except that one Certificate of each Class may be issued in a
different amount so that the sum of the denominations of all outstanding
Certificates shall equal the related Original Class Balance. The Class R
Certificates will be issued as a single certificate in fully registered
certificated form in the denomination of $100.

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

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

          (i) The Trustee shall cause the REMIC Trust to elect to be treated as
a REMIC 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.

          (j) The latest possible maturity date for each Class of Certificates
is the Distribution Date in February 2024.

          Section 4.02. REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.

          (a) At all times during the term of this Agreement, there shall be
maintained at the office of a registrar (the "Certificate Registrar") a register
(the "Certificate Register") in which, subject to such reasonable regulations as
the Certificate Registrar may prescribe, the Certificate Registrar shall provide
for the registration of Certificates and of transfers and exchanges of
Certificates as herein provided. The Trustee is initially appointed (and hereby
agrees to act in accordance with the terms hereof) as Certificate Registrar for
the purpose of registering Certificates and transfers and exchanges of
Certificates as herein provided. For so long as the Trustee acts as Certificate
Registrar, its Corporate Trust Office shall constitute the offices of the
Certificate Registrar maintained for such purposes. The Certificate Registrar
may appoint, by a written instrument delivered to the Depositor, any other bank
or trust company in New York to act as Certificate Registrar under such
conditions as the predecessor Certificate Registrar may prescribe, provided that
the predecessor Certificate Registrar shall not be relieved of any of its duties
or responsibilities hereunder by reason of such appointment. If the Trustee
resigns or is removed in accordance with the terms hereof, the successor trustee
shall immediately succeed to its predecessor's duties as Certificate Registrar.
The Depositor and, if it is no longer the Certificate Registrar, the Trustee
shall have the right to inspect the Certificate Register or to obtain a copy
thereof at all reasonable times, and to rely conclusively upon a certificate of
the Certificate Registrar as to the information set forth in the Certificate
Register.

          Every Certificateholder agrees with the Certificate Registrar and the
Trustee that neither the Certificate Registrar nor the Trustee shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Certificateholders hereunder, regardless of the source from
which such information was derived.

          (b) Subject to the preceding subsections, upon surrender for
registration of transfer of any Certificate at the offices of the Certificate
Registrar maintained for such purpose, the Trustee shall execute and the
Certificate Registrar shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Certificates of a like
Class and aggregate Percentage Interest.

          (c) At the option of any Holder, its Certificates may be exchanged for
other Certificates of the same Class of authorized denominations of a like
aggregate Percentage Interest, upon surrender of the Certificates to be
exchanged at the offices of the Certificate Registrar maintained for such
purpose. Whenever any Certificates are so surrendered for exchange, the Trustee
shall execute and the Certificate Registrar shall authenticate and deliver the
Certificates which the Certifi cateholder making the exchange is entitled to
receive.

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

          (e) 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.

          (f) All Certificates surrendered for transfer and exchange shall be
destroyed by the Certificate Registrar without liability on its part.

          Section 4.03. MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.

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

          Section 4.04. PERSONS DEEMED OWNERS.

          Prior to due presentment of a Certificate for registration of
transfer, the Depositor, the Trustee, the Certificate Registrar and any agent of
the Depositor, the Trustee or the Certificate Registrar may treat the Person in
whose name any Certificate is registered as the owner of such Certificate for
the purpose of receiving distributions pursuant to Section 3.05 and for all
other purposes whatsoever, and neither the Depositor, the Trustee, the
Certificate Registrar nor any agent of the Depositor, the Trustee or the
Certificate Registrar shall be affected by notice to the contrary.

          Section 4.05. 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. As a prerequisite to
such consent, the proposed transferee must provide the Tax Matters Person and
the Trustee with an affidavit that the proposed transferee is not a Disqualified
Organization (as defined in Subsection 4.06(b)) (and, unless the Tax Matters
Person consents 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 4.06(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 the Residual Certificate, the proposed
transferee (including the initial purchaser thereof) delivers to the Tax Matters
Person and the Trustee an affidavit in the form attached hereto as Annex 1
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 instru
mentality 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 the Federal Home
Loan Mortgage Corporation) 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 4.06(b), then the
prior Holder thereof shall, upon discovery that the transfer of such Residual
Certificate was not in fact permitted by this Subsection 4.06(b), be restored to
all rights as a Holder thereof retroactive to the date of the purported
transfer. The Trustee and the Tax Matters Person shall be under no liability to
any Person for any registration or transfer of a Residual Certificate that is
not permitted by this Subsection 4.06(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 and the Trustee 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 4.06(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 4.06(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 the REMIC Trust to fail to qualify as a REMIC.

          (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 (a "U.S.-person").


                                    ARTICLE V

                                   THE TRUSTEE

          Section 5.01. DUTIES OF TRUSTEE.

          (a) The Trustee, upon receipt of all resolutions, certificates,
statements, opinions, reports, documents, orders or other instruments furnished
to the Trustee which are specifically required to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they are in
the form required by this Agreement and the Underlying Agreements; provided,
however, that the Trustee shall not be responsible to determine, confirm or
recalculate the accuracy or content of any such resolution, certificate or other
instrument furnished to it pursuant to this Agreement including, without
limitation, the Pooled Certificate Distribution Date Statements. The Trustee
shall notify the Certificateholders and the Rating Agency of any such documents
which do not materially conform to the requirements of this Agreement in the
event that the Trustee, after so requesting of the party required to deliver the
same, does not receive satisfactorily corrected documents or a satisfactory
explanation regarding any such nonconformities.

          The Trustee shall forward or cause to be forwarded in a timely fashion
the notices, reports and statements required to be forwarded by the Trustee
pursuant to Sections 3.01, 3.02, 3.06 and 7.01.

          (b) 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) 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 by the Depositor to the Trustee
          and which on their face, do not contradict the requirements of this
          Agreement;

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

               (iii) The Trustee shall not be personally liable with respect to
          any action taken, suffered or omitted to be taken by it in good faith,
          in accordance with the direction of the Majority Certificateholders
          (or if such action or inaction relates to less than all of the Classes
          of Certificates then in accordance with the direction of the Majority
          Class Certificateholders of the applicable Class or Classes) in
          accordance with the terms of this Agreement, as to the time, method
          and place of conducting any proceeding for any remedy available to the
          Trustee, or exercising any trust or power conferred upon the Trustee,
          under this Agreement;

               (iv) No provision in this Agreement shall require the Trustee to
          expend or risk its own funds or otherwise incur any personal financial
          liability in the performance of any of its duties as Trustee
          hereunder, or in the exercise of any of its rights or powers, if the
          Trustee shall have reasonable grounds for believing that repayment of
          funds or adequate indemnity against such risk or liability is not
          reasonably assured to it; provided that this provision shall not be
          deemed to abrogate the responsibilities undertaken by the Trustee
          hereunder to perform routine administrative duties in accordance with
          the terms hereof; and

               (v) The Trustee shall not be deemed to have notice of any
          Underlying Event of Default or other fact or circumstance upon the
          occurrence of which it may be required to take action hereunder unless
          a Responsible Officer of the Trustee has actual knowledge of such
          event, fact or circumstance or unless written notice of any such event
          is received by the Trustee at its Corporate Trust Office.

          Section 5.02. FEDERAL INFORMATION RETURNS AND REPORTS TO
CERTIFICATEHOLDERS. (a) For Federal income tax purposes, the taxable year of the
REMIC Trust shall be a calendar year and the Trustee shall maintain or cause the
maintenance of the books of the REMIC Trust assets on the accrual method of
accounting.

          (b) The Trustee shall prepare and file or cause to be filed with the
Internal Revenue Service Federal tax information returns with respect to the
REMIC Trust, 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 the
REMIC Trust (the "REMIC Reporting Agent") as required by IRS Form 8811. The
Trustee shall make the elections to treat the REMIC Trust as a REMIC (which
election shall apply to the taxable period ending December 31, 1997 and each
calendar year thereafter) in such manner as the Code or applicable Treasury
regulations may prescribe. The Trustee shall sign all tax information returns
filed pursuant to this Section and any other returns as may be required by the
Code, and in doing so shall rely entirely upon, and shall have no liability for
information or calculations contained in the Pooled Certificate Distribution
Date Statements. The Trustee is hereby designated as the "Tax Matters Person"
(within the meaning of Treas. Reg. ' 1.860F-4(d)) for the REMIC Trust. 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 the REMIC Trust 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 the Residual Certificate to sign such returns or act as tax matters person.
Each Holder of the Residual Certificate shall be bound by this Section.

          (c) The Trustee shall provide upon request such information as is
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 file or cause to be filed any state
income tax returns required with respect to the REMIC Trust or the Trust Fund.

          Section 5.03. CERTAIN MATTERS AFFECTING THE TRUSTEE.

          Except as otherwise provided in Section 5.01:

               (i) The Trustee may rely and shall be protected in acting or
          refraining from acting upon any resolution, Officers' Certificate,
          certificate of auditors or any other certificate, statement,
          instrument, opinion, report, notice, request, consent, order,
          appraisal, bond or other paper or document reasonably 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 Opinion of
          Counsel shall be full and complete authorization and protection in
          respect of any action taken or suffered or omitted by it hereunder in
          good faith and in accordance with such Opinion of Counsel;

               (iii) The Trustee shall be under no obligation to exercise any of
          the trusts or powers vested in it by this Agreement or to institute,
          conduct or defend any litigation hereunder or in relation hereto at
          the request, order or direction of any of the Certificateholders
          pursuant to the provisions of this Agreement, unless such
          Certificateholders shall have offered to the Trustee reasonable
          security or indemnity against the costs, expenses and liabilities
          which may be incurred therein or thereby;

               (iv) The Trustee shall not be bound to make any investigation
          into the facts or matters stated in any resolution, certificate,
          statement, instrument, opinion, report, notice, request, direction,
          consent, order or other paper or document, but the Trustee, in its
          discretion, may make such further inquiry or investigation into such
          facts or matters as it may see fit, and, if the Trustee shall
          determine to make such further inquiry or investigation, it shall be
          entitled to the extent reasonable under the circumstances to examine
          the books, records and premises of such Person, personally or by agent
          or attorney;

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

               (vi) The Trustee may execute any of the trusts or powers
          hereunder or perform any duties hereunder either directly or by or
          through agents or attorneys and shall not be liable for the default or
          misconduct of any such agents or attorneys if selected with reasonable
          care.

          Section 5.04. TRUSTEE NOT LIABLE FOR CERTIFICATES OR POOLED
                        CERTIFICATES.

          The recitals contained herein and in the Certificates (other than the
statements attributed to, and the representations and warranties of, the Trustee
in Article II and the signature of the Trustee on each Certificate) shall be
taken as the statements of the Depositor, and the Trustee assumes no
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Agreement (other than as specifically set
forth in Section 2.03(b)) or of the Certificates (other than that the
Certificates shall be duly and validly executed by it as Trustee and
authenticated by it as Certificate Registrar) or of the Pooled Certificates or
any related document. Except as otherwise provided herein, the Trustee shall not
be accountable for the use or application by the Depositor of any of the
Certificates or of the proceeds of such Certificates, or for the use or
application of any funds paid to the Depositor in respect of the assignment and
delivery of the Pooled Certificates.

          Section 5.05. TRUSTEE MAY OWN CERTIFICATES.

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

          (a) The Trustee shall withdraw the Trustee Fee, as compensation, from
the Trustee Fee Account, as provided in Section 3.03(e) hereof.

          (b) Subject to the provisions of this paragraph, the Trustee and any
director, officer, employee or agent of the Trustee shall be entitled to be
indemnified and held harmless by the Trust Fund against any loss, liability or
expense (including, without limitation, costs and expenses of litigation, and of
investigation, counsel fees and expenses, damages, judgments, amounts paid in
settlement and out-of-pocket expenses) arising out of, or incurred in connection
with, the exercise and performance of any of the powers and duties of the
Trustee hereunder; provided that neither the Trustee nor any of the other above
specified Persons shall be entitled to indemnification pursuant to this Section
5.06(b) for (i) allocable overhead, (ii) expenses or disbursements incurred or
made by or on behalf of the Trustee in the normal course of the Trustee's
performing routine administrative duties in accordance with any of the
provisions hereof, (iii) any expense or liability specifically required to be
borne thereby pursuant to the terms hereof, or (iv) any loss, liability or
expense incurred by reason of willful misfeasance, bad faith or negligence in
the performance of the Trustee's obligations and duties hereunder, or by reason
of reckless disregard of such obligations or duties, or as may arise from a
breach of any representation, warranty or covenant of the Trustee made herein.

          The provisions of this Section 5.06(b) shall survive any resignation
or removal of the Trustee and appointment of a successor trustee.

          Section 5.07. ELIGIBILITY REQUIREMENTS FOR TRUSTEE.

          The Trustee hereunder shall at all times be a trust company or banking
institution organized and doing business under the laws of the United States of
America or any State thereof, authorized under such laws to exercise corporate
trust powers, having a combined capital, surplus and undivided profits of at
least $50,000,000 (or shall be a member of a bank holding system, the combined
capital and surplus of which is at least $50,000,000) and subject to supervision
or examination by federal or state authority. If such trust company or banking
institution publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then
for the purposes of this Section the combined capital, surplus and undivided
profits of such trust company or banking institution shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. The Trustee shall at all times meet the requirements of Section
26(a)(1) of the Investment Company Act and shall in no event be an Affiliate of
the Depositor or of any Person involved in the organization or operation of the
Depositor. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect specified in Section 5.08.

          Section 5.08. RESIGNATION AND REMOVAL OF THE TRUSTEE.

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

          (b) If at any time the Trustee shall cease to be eligible in
accordance with the provisions of Section 5.07 and shall fail to resign after
written request therefor by the Depositor, the Majority Certificateholders or if
at any time the Trustee shall become incapable of acting, or shall be adjudged
bankrupt or insolvent, or a receiver of the Trustee or of its property shall be
appointed, or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Depositor may remove the Trustee and appoint a successor
trustee by written instrument, in duplicate, one copy of which instrument shall
be delivered to the Trustee so removed and one copy to the successor trustee.

          (c) The Majority Certificateholders may at any time remove the Trustee
and appoint a successor trustee by written instrument or instruments, in
triplicate, signed by such Holders or their attorneys-in-fact duly authorized,
one complete set of which instruments shall be delivered to the Depositor, one
complete set to the Trustee so removed and one complete set to the successor so
appointed. All reasonable out-of-pocket costs and expenses incurred in
connection with such removal and replacement of the Trustee, including without
limitation, reasonable attorneys fees and expenses, shall be borne by the party
requesting such action.

          (d) Notwithstanding anything to the contrary contained herein, (i) any
resignation or removal of the Trustee and appointment of a successor trustee
pursuant to any of the provisions of this Section shall become effective only
upon acceptance of appointment by the successor trustee as provided in Section
5.09 and (ii) no entity may be appointed as a successor trustee if such
appointment would result in a withdrawal or downgrading of any then current
rating assigned to the Certificates by the Rating Agency.

          Section 5.09. SUCCESSOR TRUSTEE.

          (a) Any successor trustee appointed as provided in Section 5.08 shall
execute, acknowledge and deliver to the Depositor, the Certificateholders and to
its predecessor trustee an instrument accepting such appointment hereunder, and
thereupon the resignation or removal of the predecessor trustee shall become
effective and the appointment of such successor trustee shall become effective
and such successor trustee, without any further act, deed or conveyance, shall
become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with the like effect as if originally named as trustee
herein. The predecessor trustee shall deliver to the successor trustee the
Pooled Certificates and related documents and statements held by it hereunder,
and the Depositor, the Trustee and the predecessor trustee shall execute and
deliver such instruments and do such other things as may be required for more
fully and certainly vesting and confirming in the successor trustee all such
rights, powers, duties and obligations.

          (b) No successor trustee shall accept appointment as provided in this
Section unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 5.07.

          (c) Upon acceptance of appointment by a successor trustee as provided
in this Section, the Depositor shall mail notice of the succession of such
trustee hereunder to all Certificateholders at their addresses as shown in the
Certificate Register. If the Depositor fails to mail such notice within 10 days
after acceptance of appointment by the successor trustee, the successor trustee
shall cause such notice to be mailed at the expense of the Depositor.

          Section 5.10. MERGER OR CONSOLIDATION OF TRUSTEE.

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

          Section 5.11. 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 Fund or property securing the same may at the time be located, the
Trustee shall have the power and shall execute and deliver all instruments to
appoint one or more Persons approved by the Trustee to act as co-trustee or
co-trustees, jointly with the Trustee, or separate trustee or separate trustees,
of all or any part of the Trust Fund, and to vest in such Person or Persons, in
such capacity, such title to the Trust Fund, or any part thereof, and, subject
to the other provisions of this Section 5.11, such powers, duties, obligations,
rights and trusts as the Trustee may consider necessary or desirable. No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 5.07 hereunder; provided, that
if the co-trustee or separate trustee does not meet such eligibility standards,
the Trustee shall remain liable for its actions hereunder, and no notice to
Certificateholders of the appointment of co-trustee(s) or separate trustee(s)
shall be required under Section 5.09 hereof.

          (b) In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 5.11 all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed jointly by the Trustee and such separate trustee or
co-trustee, except to the extent that under any law of any jurisdiction in which
any particular act or acts are to be performed, the Trustee shall be incompetent
or unqualified to perform such act or acts, in which event such rights, powers,
duties and obligations (including the holding of title to the Trust Fund or any
portion thereof in any such jurisdiction) shall be exercised and performed by
such separate trustee or co-trustee at the direction of the Trustee.

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

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


                                   ARTICLE VI

                                  THE DEPOSITOR


          Section 6.01. LIABILITY OF THE DEPOSITOR.

          The Depositor shall be liable in accordance herewith only to the
extent of the respective obligations specifically imposed upon and undertaken by
the Depositor herein.

          Section 6.02. MERGER, CONSOLIDATION OR CONVERSION OF THE DEPOSITOR.

          Subject to the following paragraph, the Depositor will keep in full
effect its existence, rights and franchises as a corporation under the laws of
the jurisdiction of its incorpora tion, and will obtain and preserve its
qualification to do business as a foreign corporation in each jurisdiction in
which such qualification is or shall be necessary to protect the validity and
enforceability of this Agreement and the Certificates and to perform its duties
under this Agreement.

          The Depositor may be merged or consolidated with or into any Person,
or transfer all or substantially all of its assets to any Person, in which case
any Person resulting from any merger or consolidation to which the Depositor
shall be a party, or any Person succeeding to the business of the Depositor,
shall be the successor of the Depositor hereunder, without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

          Section 6.03. LIMITATION ON LIABILITY OF THE DEPOSITOR AND OTHERS.

          Neither the Depositor nor any of the directors, officers, employees or
agents of the Depositor shall be under any liability to the Trust Fund or the
Certificateholders for any action taken or for refraining from the taking of any
action in good faith pursuant to this Agreement, or for errors in judgment;
provided, however, that this provision shall not protect the Depositor or any
such other Person against any breach of a representation or warranty made
herein, or against any expense or liability specifically required to be borne
thereby pursuant to the terms hereof, or against any liability which would
otherwise be imposed by reason of willful misfeasance, bad faith or negligence
in the performance of obligations or duties hereunder, or by reason of reckless
disregard of such obligations and duties. The Depositor and any director,
officer, employee or agent of the Depositor may rely in good faith on any
document of any kind which, prima facie, is properly executed and submitted by
any Person respecting any matters arising hereunder. Provided that such action
is not related to its representations made in or its duties under this
Agreement, the Depositor shall not be under any obligation to appear in,
prosecute or defend any action or proceeding unless such action in its opinion
does not involve it in any expense or liability.


                                   ARTICLE VII

                                   TERMINATION


          Section 7.01. TERMINATION.

          (a) The respective obligations and responsibilities of the Depositor
and the Trustee created hereby with respect to the Certificates (other than the
obligation to make certain payments and to send certain notices to
Certificateholders as hereinafter set forth) shall terminate upon the payment
(or provision for payment) to the Certificateholders of all amounts held by or
on behalf of the Trustee and required to be paid to them hereunder on the Final
Distribution Date following receipt of the final distribution to be made on the
Pooled Certificates; provided, however, that in no event shall the trust created
hereby continue beyond the expiration of twenty-one 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's, living on the date hereof.

          (b) The Trustee shall, in accordance with Section 8.05, give a Notice
of Final Distribution to the applicable Certificateholders, the Depositor and
the Rating Agencies as soon as practicable of the Distribution Date on which the
Trustee anticipates that the final distribution will be made on the applicable
Class of Certificates, which notice shall:

               (i) specify the Distribution Date on which the final distribution
          is anticipated to be made to such Certificateholders;

               (ii) specify the amount of any such final distribution, if known;
          and

               (iii) state that the final distribution to such
          Certificateholders will be made only upon presentment and surrender of
          the applicable Certificates at the office of the Trustee therein
          specified.

If the Final Distribution with respect to a Class is not made or if
the Trust Fund is not terminated on the anticipated Distribution Date for any
reason, the Trustee shall promptly mail notice thereof to each
Certificateholder, the Depositor and to the Rating Agencies.

          (c) Upon presentment and surrender of the Certificates by the
Certificateholders of each Class on the applicable Final Distribution Date, the
Trustee shall distribute to the Certificateholders the amounts otherwise
distributable on such Distribution Date pursuant to Section 3.05(a). Any funds
not distributed on the Final Distribution Date because of the failure of any
Certificateholders to tender their Certificates shall be set aside and held in
trust for the account of the ap propriate non-tendering Certificateholders. The
Trust Fund shall terminate upon the Final Distribution Date with respect to the
last Class of Certificates outstanding. If any Certificates of a Class as to
which Notice of Final Distribution has been given pursuant to this Section 7.01
shall not have been surrendered for cancellation within six months after the
time specified in such notice, the Trustee shall mail a second notice to the
remaining Certificateholders of such Class, at their last addresses shown in the
Certificate Register, to surrender their Certificates for cancellation in order
to receive, from such funds held, the final distribution with respect thereto.
If within one year after the second notice any such Certificate shall not have
been surrendered for cancellation, the Trustee shall directly or through an
agent, take reasonable steps to contact the remaining such Certificateholders
concerning surrender of their Certificates. The costs and expenses of
maintaining such funds and of contacting Certificateholders shall be paid out of
the assets which remain held. If within two years after the second notice any
such Certificates shall not have been surrendered for cancellation, the Trustee
shall segregate all amounts distributable to the Holders thereof and shall
thereafter hold such amounts for the benefit of such Holders. No interest shall
accrue or be payable to any Certificateholder on any amount held as a result of
such Certificateholder's failure to surrender its Certificate(s) for final
payment thereof in accordance with this Section 7.01.


                                  ARTICLE VIII

                            MISCELLANEOUS PROVISIONS

          Section 8.01. AMENDMENT.

          (a) This Agreement may be amended from time to time by the Depositor
and the Trustee, without the prior consent of any Certificateholder:

               (i) to cure any ambiguity;

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

               (iii) to make any other provisions with respect to matters or
          questions arising under this Agreement which shall not be materially
          inconsistent with the existing provisions of this Agreement; and

               (iv) to make such modifications as may be permitted or required
          hereunder in connection with a repurchase or substitution of a Pooled
          Certificate pursuant to Section 2.03(c) or 2.04 hereof.

provided that such amendment shall not, as evidenced by an Opinion of Counsel
delivered to the Trustee (the expense of which shall be paid for by the
Depositor), adversely affect in any material respect the interests of any
Certificateholder.

          (b) This Agreement may also be amended from time to time by the
Depositor and the Trustee with the prior written consent of the Majority
Certificateholders (or if less than all the Classes are affected thereby, by the
Majority Class Certificateholders of the Class or Classes affected thereby) for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement or of modifying in any manner the rights
of the Certificateholders; provided, however, that no such amendment shall:

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

               (ii) modify the provisions of this Section 8.01 without the
          consent of the Holders of all Certificates; or

               (iii) be made unless and until the Trustee shall have received an
          Opinion of Counsel (at the expense of the party seeking such amendment
          but in no event at the expense of the Trust Fund) to the effect that
          such amendment shall not cause the REMIC Trust to fail to qualify as a
          REMIC for federal income tax purposes.

          (c) Promptly after the execution of any such amendment the Trustee
shall furnish written notification of the substance of such amendment to each
Certificateholder. It shall not be necessary for the consent of
Certificateholders under this Section 8.01 to approve the particular form of any
proposed amendment, but it shall be sufficient if such consent shall approve the
substance thereof. The manner of obtaining such consents and of evidencing the
authorization of the execution thereof by Certificateholders shall be subject to
such reasonable regulations as the Trustee may prescribe.

          Section 8.02. COUNTERPARTS.

          This Agreement may be executed simultaneously in any number of
counterparts, each of which counterparts shall be deemed to be an original, and
such counterparts shall constitute but one and the same instrument.

          Section 8.03. LIMITATION ON RIGHTS OF CERTIFICATE HOLDERS.

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

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

          (c) No Certificateholder shall have any right by virtue of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
Holder previously shall have given to the Trustee and the Depositor a written
notice of default hereunder, and of the continuance thereof, as herein before
provided, and unless also the Majority Certificateholders (or in the event that
such action or proceeding relates to less than all of the Classes, the Majority
Class Certificateholders of the related Class or Classes) shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee, for 30 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. For the
prosecution and enforcement of the rights granted under this Section, each and
every Certificateholder and the Trustee shall be entitled to such relief as can
be given either at law or in equity.

          Section 8.04. GOVERNING LAW.
