Ladies and Gentlemen:

     ABN AMRO Mortgage Corporation (the "Company"), a Delaware corporation, 
has authorized the issuance and sale of Mortgage Pass-Through Certificates 
(the "Certificates") evidencing interests in pools of mortgage loans (the 
"Mortgage Loans").  The Certificates may be issued in various series, and, 
within each series, in one or more classes, and, within each class, in one or 
more sub-classes, in one or more offerings on terms determined at the time of 
sale (each such series, a "Series" and each such class, a "Class").  Each 
Series of the Certificates will be issued under a separate Pooling and 
Servicing Agreement (each, a "Pooling and Servicing Agreement") with respect 
to such Series among the Company, as depositor, a servicer to be identified 
in the prospectus supplement for each such Series (the "Servicer") and a 
trustee to be identified in the prospectus supplement for each such Series 
(the "Trustee").  The Certificates of each Series will evidence specified 
interests in separate pools of Mortgage Loans (each a "Mortgage Pool"), and 
certain other property held in trust with respect to such Series (each, a 
"Trust Fund").

     The Certificates are more fully described in a Registration Statement 
which the Company has furnished to you. Capitalized terms used but not 
defined herein shall have the meanings given to them in the Pooling and 
Servicing Agreement. The term "you" as used herein, unless the context 
otherwise requires, shall mean you and such persons as are named as 
co-managers in the applicable Terms Agreement (defined below).

     Whenever the Company determines to make an offering of Certificates 
pursuant to this Agreement through you or through an underwriting syndicate 
managed by you it will enter into an agreement (the "Terms Agreement") 
providing for the sale of such Certificates to, and the purchase 

<PAGE>

and offering thereof by, you and such other underwriters, if any, selected by 
you as have authorized you to enter into such Terms Agreement on their behalf 
(the "Underwriters," which term shall include you whether acting alone in the 
sale of Certificates or as a member of an underwriting syndicate; as the 
context requires, Lehman Brothers Inc. is sometimes referred to individually 
herein as "Lehman Brothers" and ABN AMRO Incorporated is sometimes referred 
to individually herein as "AAI").  The Terms Agreement relating to each 
offering of Certificates shall specify, among other things, the stated 
balance or balances of Certificates to be issued, the price or prices at 
which the Certificates are to be purchased by the Underwriters from the 
Company and the initial public offering price or prices or the method by 
which the price or prices at which such Certificates are to be sold will be 
determined.  A Terms Agreement, which shall be substantially in the form of 
Exhibit A hereto, may take the form of an exchange of any standard form of 
written telecommunication between you and the Company.  Each such offering of 
Certificates which the Company elects to make pursuant to this Agreement will 
be governed by this Agreement, as supplemented by the applicable Terms 
Agreement, and this Agreement and such Terms Agreement shall inure to the 
benefit of and be binding upon the Underwriters participating in the offering 
of such Certificates.

     SECTION 1.  REPRESENTATIONS AND WARRANTIES.  (a)  The Company represents 
and warrants to you as of the date hereof, and to the Underwriters named in 
the applicable Terms Agreement, all as of the date of such Terms Agreement 
(in each case, the "Representation Date"), as follows (any representations 
and warranties so made to the Underwriters named in an applicable Terms 
Agreement respecting the Certificates being deemed to relate only to the 
Certificates described therein):

          (1)  The Company has filed with the Securities and Exchange Commission
     (the "Commission") a registration statement on Form S-3 (No. 333-57027),
     relating to the offering of Certificates from time to time in accordance
     with Rule 415 under the Securities Act of 1933, as amended (the "1933
     Act"), and has filed, and proposes to file, such amendments thereto as may
     have been required to the date hereof and the same has become effective
     under the 1933 Act and the rules of the Commission thereunder (the
     "Regulations") and no stop order suspending the effectiveness of such
     registration statement has been issued and no proceedings for that purpose
     have been initiated or, to the Company's knowledge, threatened, by the
     Commission.  Such registration statement, including incorporated documents,
     exhibits and financial statements, as amended at the time when it became
     effective under the 1933 Act, and the prospectus relating to the sale of
     Certificates by the Company constituting a part thereof, as from time to
     time each is amended or supplemented pursuant to the 1933 Act or otherwise,
     are referred to herein as the "Registration Statement" and the
     "Prospectus," respectively; provided, however, that a supplement to the
     Prospectus contemplated by Section 3(a) hereof (a "Prospectus Supplement")
     shall be deemed to have supplemented the Prospectus only with respect to
     the offering or offerings of Certificates to which it relates.  Any
     reference herein to the Registration Statement, a preliminary prospectus,
     the Prospectus or the Prospectus Supplement shall be deemed to refer to and
     include the documents incorporated by reference therein pursuant to Item 12
     of Form S-3 which were filed under the Securities Exchange Act of 1934, as
     amended (the "1934 Act") on or before the date on which the Registration
     Statement, as amended, became effective or 

                                       -2-
<PAGE>

     the issue date of such preliminary prospectus, Prospectus, or Prospectus
     Supplement, as the case may be; and any reference herein to the terms 
     "amend," "amendment" or supplement with respect to the Registration 
     Statement, any preliminary prospectus, the Prospectus or the Prospectus 
     Supplement shall be deemed to refer to and include the filing of any 
     document under the 1934 Act after the date on which the Registration 
     Statement became effective or the issue date of any preliminary prospectus,
     the Prospectus or the Prospectus Supplement, as the case may be, deemed to
     be incorporated therein by reference.  The Registration Statement and 
     Prospectus, at the time the Registration Statement became effective did, 
     and as of the applicable Representation Date will, conform in all material
     respects to the requirements of the 1933 Act and the Regulations.  The 
     Registration Statement, at the time it became effective did not, and as of
     the applicable Representation Date and the applicable Closing Time (as 
     defined in Section 2 hereof) will not, contain any untrue statement of a 
     material fact or omit to state any material fact required to be stated 
     therein or necessary to make the statements therein not misleading.  The 
     Prospectus, as amended or supplemented as of the applicable Representation
     Date and the applicable Closing Time (as defined in Section 2 hereof), 
     will not contain any untrue statement of a material fact or omit to state
     a material fact necessary in order to make the statements therein, in the 
     light of the circumstances under which they were made, not misleading; 
     provided, however, that the representations and warranties in this 
     subsection shall not apply to (i) statements in, or omissions from, the 
     Registration Statement or Prospectus made in reliance upon and in 
     conformity with information furnished to the Company in writing by the 
     Underwriters expressly for use in the Registration Statement or Prospectus
     or (ii) the Lehman Brothers Information (as defined in Section 10 hereof).
     The conditions to the use by the Company of a registration statement on 
     Form S-3 under the 1933 Act, as set forth in the General Instructions to
     Form S-3, have been satisfied with respect to the Registration Statement 
     and the Prospectus.  There are no contracts or documents of the Company 
     which are required to be described in the Registration Statement or 
     Prospectus or filed as exhibits to the Registration Statement pursuant 
     to the 1933 Act or the Regulations which have not been so described or
     filed.

          (2)  The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of the State of Delaware with
     corporate power and authority to enter into and perform its obligations
     under this Agreement, the applicable Pooling and Servicing Agreement, and
     with respect to a Series of Certificates, the Certificates and the
     applicable Terms Agreement; and the Company is duly qualified or registered
     as a foreign corporation to transact business and is in good standing in
     each jurisdiction in which the ownership or lease of its properties or the
     conduct of its business requires such qualification.

          (3)  The Company is not in violation of its certificate of
     incorporation or by-laws or in default in the performance or observance of
     any material obligation, agreement, covenant or condition contained in any
     material contract, indenture, mortgage, loan agreement, note, lease or
     other material instrument to which it is a party or by which it or its
     properties may be bound, which default might result in any material adverse
     change in the 

                                   -3-

<PAGE>

     financial condition, earnings, affairs or business of the Company or 
     which might materially and adversely affect the properties or
     assets thereof or the Company's ability to perform its obligations under
     this Agreement, the applicable Terms Agreement or the applicable Pooling
     and Servicing Agreement.

          (4)  The execution and delivery by the Company of this Agreement, the
     applicable Terms Agreement and the applicable Pooling and Servicing
     Agreement and the signing of the Registration Statement by the Company are
     within the corporate power of the Company and have been duly authorized by
     all necessary corporate action on the part of the Company; and with respect
     to a Series of Certificates described in the applicable Terms Agreement,
     neither the issuance and sale of the Certificates to the Underwriters, nor
     the execution and delivery by the Company of this Agreement, such Terms
     Agreement and the related Pooling and Servicing Agreement, nor the
     consummation by the Company of the transactions herein or therein
     contemplated, nor compliance by the Company with the provisions hereof or
     thereof, will conflict with or result in a breach or violation of any of
     the terms or provisions of, or constitute a default under, or result in the
     creation or imposition of any lien, charge or encumbrance upon any property
     or assets of the Company other than as contemplated by a Pooling and
     Servicing Agreement, pursuant to any material indenture, mortgage, contract
     or other material instrument to which the Company is a party or by which it
     is bound or to which the property or assets of the Company are subject, or
     result in the violation of the provisions of the certificate of
     incorporation or by-laws of the Company or any statute or any material
     order, rule or regulation of any court or governmental agency or body
     having jurisdiction over the Company or any of its properties.

          (5)  This Agreement has been, and each applicable Terms Agreement when
     executed and delivered as contemplated hereby and thereby will have been,
     duly authorized, executed and delivered by the Company, and each
     constitutes, or will constitute when so executed and delivered, a legal,
     valid and binding instrument enforceable against the Company in accordance
     with its terms (assuming due authorization, execution and delivery by the
     other parties thereto), subject (a) to applicable bankruptcy, insolvency,
     reorganization, moratorium, or other similar laws affecting creditors'
     rights generally, (b) as to enforceability to general principles of equity
     (regardless of whether enforcement is sought in a proceeding in equity or
     at law) and (c) as to enforceability with respect to rights of indemnity
     thereunder, to limitations of public policy under applicable securities
     laws.

          (6)  Each applicable Pooling and Servicing Agreement when executed and
     delivered as contemplated hereby and thereby will have been duly
     authorized, executed and delivered by the Company, and will constitute when
     so executed and delivered, a legal, valid and binding instrument
     enforceable against the Company in accordance with its terms (assuming due
     authorization, execution and delivery by the other parties thereto),
     subject (a) to applicable bankruptcy, insolvency, reorganization,
     moratorium or other similar laws affecting creditors' rights generally and

     Agreement, nor the consummation by Standard Federal of the transactions

     of Standard Federal or any statute or any order, rule or regulation of any
     court or governmental agency or body having jurisdiction over Standard
     Federal or any of its properties.

herein set forth.

     Payment of the purchase price for, and delivery of, any Certificates to be

payment shall be made to the Company in immediately available Federal funds
wired to such bank as may be designated by the Company.  Such Certificates shall
be in such denominations and registered in such names as you may request in

     SECTION 3.  COVENANTS OF THE COMPANY.  The Company covenants with each of
you and each Underwriter participating in an offering of Certificates pursuant
to a Terms Agreement, with respect to such Certificates and such offering, as
follows:

          (a)  Immediately following the execution of each Terms Agreement, the
     Company will prepare a Prospectus Supplement setting forth the principal
     amount of Certificates covered thereby, the price or prices at which the
     Certificates are to be purchased by the Underwriters, either the initial
     public offering price or prices or the method by which the price or prices
     by which the Certificates are to be sold will be determined, the selling
     concession(s) and reallowance(s), if any, any delayed delivery
     arrangements, and such other information as you and the Company deem
     appropriate in connection with the offering of the Certificates.  The
     Company will furnish you a copy of the Prospectus Supplement for your
     review prior to filing such Prospectus Supplement with the Commission. 
     Thereafter, the Company will promptly transmit copies of the Prospectus
     Supplement to the Commission for filing pursuant to Rule 424 under the 1933
     Act and will furnish to the Underwriters as many copies of the Prospectus
     and such Prospectus Supplement as you shall reasonably request.

          (b)  If the delivery of a prospectus is required at any time in
     connection with the offering or sale of the Certificates described in the
     relevant Terms Agreement and if at such time any event shall have occurred
     as a result of which the Prospectus as then amended or supplemented would
     include an untrue statement of a material fact or omit to state any
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made when such Prospectus
     is delivered, not misleading, or, if for any other reason it shall be
     necessary during such period of time to amend or supplement the Prospectus
     in order to comply with the 1933 Act, the Company agrees to notify you
     promptly and upon your request so to amend or supplement the Prospectus and
     to prepare and furnish without charge to each Underwriter and to any dealer
     in securities as many copies as you may from time to time reasonably
     request of an amended Prospectus or a supplement to the Prospectus which
     will correct such statement or omission or effect such compliance.

          (c)  During any period in which the delivery of a prospectus is
     required at any time in connection with the offering or sale of the
     Certificates described in the relevant Terms Agreement the Company will
     give you reasonable notice of its intention to file any amendment to the
     Registration Statement or any amendment or supplement to the Prospectus,
     whether pursuant to the 1933 Act or otherwise, and will furnish you with
     copies 

                                 -9-

<PAGE>

     of any such amendment or supplement or other documents proposed to
     be filed a reasonable time in advance of filing.

          (d)  During any period in which the delivery of a prospectus is
     required at any time in connection with the offering or sale of the
     Certificates described in the relevant Terms Agreement the Company will
     notify you promptly (i) of the effectiveness of any amendment to the
     Registration Statement, (ii) of the mailing or the delivery to the
     Commission for filing of any supplement to the Prospectus or any document
     other than quarterly and annual reports to be filed pursuant to the 1934
     Act, (iii) of the receipt of any comments from the Commission with respect
     to the Registration Statement, the Prospectus or any Prospectus Supplement,
     (iv) of any request by the Commission for any amendment to the Registration
     Statement or any amendment or supplement to the Prospectus or for
     additional information, (v) of the receipt by the Company of any
     notification with respect to the suspension of the qualification of the
     Certificates for sale in any jurisdiction or the threat of any proceeding
     for that purpose and (vi) of the issuance by the Commission of any stop
     order suspending the effectiveness of the Registration Statement or the
     initiation of any proceedings for that purpose.  The Company will use its
     best efforts to prevent the issuance of any such stop order and, if any
     stop order is issued, to obtain the lifting thereof as soon as possible.

          (e)  The Company agrees, so long as the Certificates shall be
     outstanding, or until such time as you shall cease to maintain a secondary
     market in the Certificates, whichever first occurs, to deliver to you the
     annual statement as to compliance delivered to the Trustee pursuant to the
     applicable Pooling and Servicing Agreement and the annual statement of a
     firm of independent public accountants furnished to the Trustee pursuant to
     the applicable Pooling and Servicing Agreement, as soon as such statements
     are furnished to the Company.

          (f)  The Company will deliver to you as many conformed copies of the
     Registration Statement (as originally filed) and of each amendment thereto
     (including exhibits filed therewith or incorporated by reference therein
     and documents incorporated by reference in the Prospectus) as you may
     reasonably request.

          (g)  The Company will endeavor, in cooperation with you, to qualify
     the Certificates for offering and sale under the applicable securities laws
     of such states and other jurisdictions of the United States as you may
     reasonably designate, and will maintain or cause to be maintained such
     qualifications in effect for as long as may be required for the
     distribution of the Certificates, provided that in connection therewith the
     Company shall not be required to qualify as a foreign corporation or to
     file a general consent to service of process in any jurisdiction.  The
     Company will file or cause the filing of such statements and reports as may
     be required by the laws of each jurisdiction in which the Certificates have
     been qualified as above provided.

     SECTION 4.  CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The obligations of the
Underwriters to purchase Certificates pursuant to any Terms Agreement shall be

     Certificates, contained an untrue statement of a material fact or omitted
     to state a material fact necessary in order to make the statements therein,

     for inclusion of additional information in the Registration Statement or
     the Prospectus or the Prospectus Supplement shall have been complied with

          imposition of any lien, charge or encumbrance upon any property or
          assets of the Company pursuant to, any contract, indenture, mortgage,

          registrations or qualifications as may be required under state
          securities or Blue Sky laws in connection with the purchase and
          distribution of the Certificates by the Underwriters.

          headings "Certain Federal Income Tax Consequences" and "ERISA
          Considerations", to the extent that they describe matters of United
          States federal income tax law or ERISA or legal conclusions with
          respect thereto, have been prepared or reviewed by such counsel and
          are accurate in all material respects and (B) the statements in the
          Prospectus under the heading "Certain Legal Aspects of the Mortgage
          Loans," to the extent they constitute matters of United States federal
          law or legal conclusions with respect thereto, while not purporting to
          discuss all possible consequences of investment in the Certificates,
          are accurate in all material respects with respect to those
          consequences or matters discussed therein.

               (xii) The statements in the Prospectus and the applicable
          Prospectus Supplement under the caption "Description of the
          Certificates", insofar as they purport to summarize certain terms of
          the Certificates and the applicable Pooling and Servicing Agreement,
          constitute a fair summary of the provisions purported to be
          summarized.

               (xiii)    The Trust Funds created by the applicable Pooling and
          Servicing Agreement is not, and will not as a result of the offer and
          sale of the Certificates as contemplated in the Prospectus and in this
          Agreement become, required to be registered as an "investment company"
          under the 1940 Act.

               (xiv) The Classes of Certificates so designated in the
          Prospectus Supplement will be "mortgage related securities", as
          defined in Section 3(a)(41) of the 1934 Act, so long as the
          Certificates are rated in one of the two highest grades by at least
          one nationally recognized statistical rating organization.  

                                    -13-

               (xv)  Assuming (a) ongoing compliance with all of the provisions
          of the Pooling and Servicing Agreement and (b) the filing of
          elections, in accordance with the Pooling and Servicing Agreement, to
          be treated as "real estate mortgage investment conduits" ("REMICs")
          pursuant to Section 860D of the Internal Revenue Code of 1986, as
          amended (the "Code") for Federal income tax purposes, REMIC I and
          REMIC II of the Trust Fund will qualify as REMICs as of the Closing
          Date and will continue to qualify as REMICs for so long as there is
          compliance with amendments after the date hereof to any applicable
          provisions of the Code and applicable Treasury Regulations.

               (xvi) Assuming that REMIC I and REMIC II of the Trust Fund are
          treated as REMICs for Federal income tax purposes, neither of them nor
          the Trust Fund will be subject as an entity to any tax imposed on
          income, franchise or capital stock by the laws of Illinois.

     Such counsel shall deliver to you such additional opinions addressing the
transfer by the Company to the Trustee of its right, title and interest in and
to the Mortgage Loans and other property included in the Trust Fund at the
Closing Time as may be required by each Rating Agency rating the Certificates.

     Such counsel shall state that it has participated in conferences with
officers and other representatives of the Company, your counsel, representatives
of the independent accountants for the Company and you at which the contents of
the Registration Statement and the Prospectus and related matters were discussed
and, although such counsel is not passing upon and does not assume
responsibility for, the factual accuracy, completeness or fairness of the
statements contained in the Registration Statement or the Prospectus (except as
stated in paragraphs (xi) and (xii) above) and has made no independent check or
verification thereof for the purpose of rendering its opinion, on the basis of
the foregoing, nothing has come to their attention that leads such counsel to
believe that either the Registration Statement, at the time it became effective
and at the applicable Closing Time, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading, or that the Prospectus
contained or contains as of the date thereof and at the applicable Closing Time
any untrue statement of a material fact or omitted or omits to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading, except that such counsel need
express no view with respect to the financial statements, schedules and other
financial and statistical data included in or incorporated by reference into the
Registration Statement, the Prospectus or the Prospectus Supplement.

     Such counsel may state that their opinions relate only to laws of the State
of New York, the Federal laws of the United States and the General Corporation
Law of the State of Delaware.

                                 -14-

     In rendering such opinions, such counsel may rely, as to matters of fact,
to the extent deemed proper and stated therein, on certificates of responsible
officers of the Company, the Trustee or public officials.

               (2)   The favorable opinion of counsel to the Trustee, dated as
          of the applicable Closing Time, addressed to you and in form and scope
          satisfactory to your counsel, to the effect that:

                    (i)   The Trustee is a national association, duly organized
          and validly existing in good standing under the laws of the United
          States, and has all requisite power and authority to enter into the
          Pooling and Servicing Agreement and to perform its obligations
          thereunder.

                    (ii)  To the knowledge of such counsel, there is no action,
          suit, proceeding or investigation pending or threatened against the
          Trustee that could materially adversely affect the ability of the
          Trustee to perform its obligations under the Pooling and Servicing
          Agreement.

                    (iii) The Trustee has duly authorized, executed and
          delivered the applicable Pooling and Servicing Agreement and such
          Pooling and Servicing Agreement will constitute the legal, valid and
          binding obligation of the Trustee.

                    (iv)  The Trustee has full power and authority to execute
          and deliver the applicable Pooling and Servicing Agreement and to
          perform its obligations thereunder.

                    (v)   No consent, approval or authorization of, or
          registration, declaration or filing with, any court or governmental
          agency or body of the jurisdiction of its organization is required for
          the execution, delivery or performance by the Trustee of the Pooling
          and Servicing Agreement.

                    (vi)  The Certificates have been duly and validly executed,
          authenticated and delivered by the Trustee in accordance with the
          Pooling and Servicing Agreement.

                    (vii) The performance by the Trustee of its duties pursuant
          to the Pooling and Servicing Agreement does not conflict with or
          result in a breach or violation of any term or provision of, or
          constitute a default under, any statute or regulation currently
          governing the Trustee.

          In rendering such opinion, such counsel may rely, as to matters of
fact, to the extent deemed proper and stated therein, on certificates of
responsible officers of the Trustee or public officials.

               (3)  The favorable opinion of counsel to the Servicer, dated as
          of the applicable Closing Time, addressed to you and in form and scope
          satisfactory to your counsel, to the effect that:

                    (i)   The Servicer is validly existing as a corporation in
          good standing under the laws of the jurisdiction of its incorporation.

                    (ii)  The execution and delivery by the Servicer of the
          applicable Pooling and Servicing Agreement is within the corporate
          power of the Servicer and has been duly authorized by all necessary
          corporate action on the part of the Servicer; and to the knowledge of
          such counsel, neither the execution and delivery of either such
          instrument, nor the consummation of the transactions provided for
          therein, nor compliance with the provisions thereof, will conflict
          with or constitute a breach of, or default under, any contract,
          indenture, mortgage, loan agreement, note, lease, deed of trust, or
          other instrument to which the Servicer is a party or by which it may
          be bound, nor will such action result in any violation of the
          provisions of the charter or by-laws of the Servicer or to the
          knowledge of such counsel, any law, administrative regulation or
          administrative or court decree.

                    (iii) The applicable Pooling and Servicing Agreement has
          been duly executed and delivered by the Servicer and constitutes a
          legal, valid and binding obligation of the Servicer enforceable
          against the Servicer in accordance with its terms, except that such
          enforceability thereof may be subject to applicable bankruptcy,
          insolvency, reorganization, moratorium or other similar laws affecting
          creditors' rights generally and subject, as to enforceability, to
          general principles of equity (regardless whether enforcement is sought
          in a proceeding in equity or at law).

                    (iv)  To the knowledge of such counsel, the execution,
          delivery and performance by the Servicer of the applicable Pooling and
          Servicing Agreement do not require the consent or approval of, the
          giving of notice to, the registration with, or the taking of any other
          action in respect of any federal, state or other governmental agency
          or authority which has not previously been effected.

                    (v)   To the knowledge of such counsel, there is no action,
          suit or proceeding of which such counsel is aware before or by any
          court or governmental agency or body, domestic or foreign, now pending
          or threatened against the Servicer which might materially and
          adversely affect the performance by the Servicer under, or the
          validity or enforceability of the applicable Pooling and Servicing
          Agreement.

                    (vi)  The description of the Servicer in the applicable
          Prospectus Supplement is true and correct in all material respects.

               (4)  The favorable opinion or opinions, dated as of the
          applicable Closing Time, of counsel for the Underwriters, acceptable
          to the Underwriters.

                                    -16-

<PAGE>

               (5)  The favorable opinion, dated the applicable Closing Time of
          counsel for Standard Federal, acceptable to the Underwriters.

          (c)  At the applicable Closing Time you shall have received a
     certificate of the President or a Vice President and the Treasurer or the
     Secretary of each of the Company and Standard Federal, dated as of such
     Closing Time, to the effect that the representations and warranties of the
     Company or Standard Federal, as the case may be, contained in Section 1 are
     true and correct with the same force and effect as though such Closing Time
     were a Representation Date and that the Company or Standard Federal, as the
     case may be, has complied with all agreements and satisfied all the
     conditions on its part to be performed or satisfied at or prior to the
     Closing Time.

          (d)  You shall have received from Ernst & Young with respect to
     certain information relating to the Company and from Deloitte & Touche with
     respect to certain other information in the Prospectus Supplement, or other
     independent certified public accountants acceptable to you, letters, dated
     as of the date of the applicable Terms Agreement and as of the applicable
     Closing Time, delivered at such times, in the form and substance reasonably
     satisfactory to you.

          (e)  At the applicable Closing Time, with respect to a Series of
     Certificates, each of the representations and warranties of the Servicer
     set forth in the related Pooling and Servicing Agreement will be true and
     correct and you shall have received a Certificate of an Executive Vice
     President, Senior Vice President or Vice President of the Servicer, dated
     as of such Closing Time, to such effect.

          (f)  At the applicable Closing Time, with respect to a Series of
     Certificates, the Certificates shall have received the certificate rating
     or ratings specified in the related Terms Agreement.

          (g)  At the applicable Closing Time, counsel for the Underwriters
     shall have been furnished with such other documents and opinions as they
     may reasonably require for the purpose of enabling them to pass upon the
     issuance and sale of the Certificates as herein contemplated and related
     proceedings or in order to evidence the accuracy and completeness of any of
     the representations and warranties, or the fulfillment of any of the
     conditions, herein contained; and all proceedings taken by the Company in
     connection with the issuance and sale of the Certificates as herein
     contemplated shall be reasonably satisfactory in form and substance to you
     and counsel for the Underwriters.

     If any condition specified in this Section shall not have been fulfilled
when and as required to be fulfilled or, if any of the opinions and certificates
required hereby shall not be in all material respects reasonably satisfactory to
you and your counsel, the applicable Terms Agreement may be terminated by you by
notice to the Company at any time at or prior to the applicable Closing Time,
and such termination shall be without liability of any party to any other party
except as provided in Section 5.

                                 -17-

          SECTION 5.  PAYMENT OF EXPENSES.  The Company covenants and agrees
with the Underwriters that the Company will pay or cause to be paid all expenses
incident to the performance of its obligations under this Agreement and all
other fees and expenses associated with the transactions referred to herein, 
including, but not limited to, the fees and expenses of the Trustee, Rating
Agencies, printer, accounting firms, the fees and expenses relating to the
establishment of the Company's shelf registration statement and related ongoing
fees and expenses; provided, however, that the Underwriters covenant and agree
to pay all of their own costs and expenses, including underwriting and due
diligence expenses, the fees of their counsel, transfer taxes on resale of any
of the Certificates by them and any advertising expenses connected with any
offers they may make.

     SECTION 6.  INDEMNIFICATION.

          (a)  The Company and Standard Federal, jointly and severally, will
     indemnify and hold harmless the Underwriters and each person, if any, who
     controls the Underwriters within the meaning of the 1933 Act, against any
     losses, claims, damages, expenses or liabilities, joint or several, to
     which such Underwriter or such controlling person may become subject, under
     the 1933 Act or otherwise, insofar as such losses, claims, damages,
     expenses or liabilities (or actions in respect thereof) arise out of or are
     based upon an untrue statement or alleged untrue statement of a material
     fact contained in the Registration Statement (or any amendment thereto) or
     the Prospectus (or any amendment or supplement thereto), or arise out of or
     are based upon the omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein, in light of the circumstances under which they were made, not
     misleading in each case in respect of the relevant Certificates, and will
     reimburse each such indemnified party for any legal or other expenses
     reasonably incurred by it in connection with investigating or defending any
     such action or claim; provided, however, that the Company shall not be
     liable in any such case to the extent that any such loss, claim, damage or
     liability arises out of or is based upon an untrue statement or alleged
     untrue statement or omission or alleged omission made in any such document
     in reliance upon and in conformity with written information furnished to
     the Company by or on behalf of the Underwriters expressly for use therein. 
     This indemnity agreement will be in addition to any liability which the
     Company may otherwise have.

          (b)  The Underwriters, severally and not jointly, will indemnify and
     hold harmless the Company, each of its officers who signed the Registration
     Statement, its directors, and any person controlling the Company within the
     meaning of the 1933 Act against any losses, claims, damages, expenses or
     liabilities to which the Company or any such officer, director or
     controlling person may become subject, under the 1933 Act or otherwise,
     insofar as such losses, claims, damages, expenses or liabilities (or
     actions in respect thereof) arise out of or are based upon an untrue
     statement or alleged untrue statement of a material fact contained in the
     Registration Statement (or any amendment thereto) or the Prospectus (or any
     amendment or supplement thereto), or arise out of or are based upon the
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make 

                                    -18-

<PAGE>

     the statements therein, in light of the circumstances under which they
     were made, not misleading, in each case to the extent, but only to the 
     extent, that such untrue statement or alleged untrue statement or omission
     or alleged omission was made in reliance upon and in conformity with 
     written information furnished to the Company by or on behalf of the 
     Underwriters expressly for use therein and will reimburse the Company or 
     any such director, officer or controlling person for any legal or other 
     expenses reasonably incurred by the Company, any such officer, director 
     or controlling person in connection with investigating or defending any 
     such action or claim.  This indemnity agreement is in addition to any 
     liability which the Underwriters may otherwise have.  The Company 
     acknowledges that, unless otherwise set forth in the applicable Terms 
     Agreement, the statements set forth in the last paragraph of the cover 
     page, and fourth sentence of the first paragraph under the caption 
     "Method of Distribution" each as included in the applicable Prospectus 
     Supplement relating to a Series of Certificates, together with the Lehman
     Brothers Information (as defined in Section 10 hereof) relating to a 
     Series of Certificates constitute the only information furnished in 
     writing by or on behalf of the Underwriters expressly for use in the 
     Registration Statement relating to such Series of Certificates as 
     originally filed or in any amendment thereof, any related preliminary 
     prospectus or the Prospectus or in any amendment thereof or supplement 
     thereto, as the case may be.

          (c)  Promptly after receipt by an indemnified party under this Section
     of notice of the commencement of any action, such indemnified party shall,
     if a claim in respect thereof is to be made against an indemnifying party
     under this Section, notify such indemnifying party in writing of the
     commencement thereof; but the omission so to notify the indemnifying party
     shall not relieve it from any liability which it may have to any
     indemnified party otherwise than under this Section.  In case any such
     action shall be brought against any indemnified party and it shall notify
     the indemnifying party of the commencement thereof, the indemnifying party
     shall be entitled to participate therein and, to the extent that it shall
     wish, jointly with any other indemnifying party similarly notified, to
     assume the defense thereof, with counsel satisfactory to such indemnified
     party (who shall not, except with the consent of the indemnified party, be
     counsel to the indemnifying party); and, after notice from the indemnifying
     party to such indemnified party of its election so to assume the defense
     thereof, the indemnifying party shall not be liable to such indemnified
     party under this Section for any legal expenses of other counsel or any
     other expenses, in each case subsequently incurred by such indemnified
     party, in connection with the defense thereof other than reasonable costs
     of investigation.  Notwithstanding the foregoing, the indemnified party or
     parties shall have the right to employ its or their own counsel in any such
     case and the fees and expenses of one such counsel shall be at the expense
     of the indemnifying party if (i) the employment of such counsel shall have
     been authorized in writing by the indemnifying party in connection with the
     defense of such action, (ii) the indemnifying party shall not have employed
     counsel to have charge of the defense of such action within a reasonable
     time after notice of commencement of the action, or (iii) the indemnified
     party or parties shall have reasonably concluded that there may be defenses
     available to it or them and/or other indemnified parties which are
     different from or additional to those available to the indemnifying party
     (in which case the indemnifying party shall not 

                               -19-

<PAGE>

     have the right to direct the defense of such action on behalf of the 
     indemnified party).  Anything in this subsection to the contrary 
     notwithstanding, an indemnifying party shall not be liable for any 
     settlement of any claim or action effected without its written consent;
     provided, however, that such consent was not unreasonably withheld.

          (d)  If the indemnification provided for in this Section 6 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsection (a) or (b) above in respect of any losses, claims, damages,
     expenses or liabilities (or actions in respect thereof) referred to
     therein, then each indemnifying party shall contribute to the amount paid
     or payable by such indemnified party as a result of such losses, claims,
     damages, expenses or liabilities (or actions in respect thereof) in such
     proportion as is appropriate to reflect the relative benefits received by
     the Company on the one hand and the Underwriters on the other from the
     offering of the Certificates to which such loss, claim, damage, expense or
     liability (or actions in respect thereof) relates.  If, however, the
     allocation provided by the immediately preceding sentence is not permitted
     by applicable law, then each indemnifying party shall contribute to such
     amount paid or payable by such indemnified party in such proportion as is
     appropriate to reflect not only such relative benefits but also the
     relative fault of the Company on the one hand and the Underwriters on the
     other in connection with the statements or omissions which resulted in such
     losses, claims, damages or liabilities (or actions in respect thereof), as
     well as any other relevant equitable considerations.  The relative benefits
     received by the Company on the one hand and the Underwriters on the other
     shall be deemed to be in the same proportion as the total net proceeds from
     such offering (before deducting expenses) received by the Company bear to
     the total underwriting discounts and commissions (or in the case of a
     public offering in negotiated transactions, the difference between the
     proceeds to the Company and the aggregate price received from the public)
     received by such Underwriters.   The relative fault of the Company on the
     one hand and the Underwriters on the other shall be determined by reference
     to, among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission or alleged omission to state a material fact
     relates to information supplied by the Company on the one hand or such
     Underwriters on the other and the parties' relative intent, knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission.  Notwithstanding anything to the contrary in this Section
     6(d), if the losses, claims, damages or liabilities (or actions in respect
     thereof) referred to in this Section 6(d) arise out of an untrue statement
     or alleged untrue statement of a material fact contained in any Lehman
     Brothers 8-K (as such term is defined in Section 10 hereof) then each
     indemnifying party shall contribute to the amount paid or payable by such
     indemnified party as a result of such losses, claims, damages or
     liabilities (or actions in respect thereof) in such proportion as is
     appropriate to reflect the relative fault of the Company on the one hand
     and the Underwriters on the other (determined in accordance with the
     preceding sentence) in connection with the statements or omissions in such
     Lehman Brothers 8-K which resulted in such losses, claims, damages or
     liabilities (or actions in respect thereof), as well as any other equitable
     considerations.  The Company and the Underwriters agree that it would not
     be just and equitable if contribution pursuant to this subsection (d) were
     determined by pro rata allocation even if the Underwriters were treated as
     one entity for such purpose or by any 

                                    -20-

<PAGE>

     other method of allocation which does not take account of the equitable 
     considerations referred to in this subsection (d). The amount paid or 
     payable by an indemnified party as a result of the losses, claims, damages
     or liabilities (or actions in respect thereof) referred to above in this 
     subsection (d) shall be deemed to include any legal or other expenses 
     reasonably incurred by such indemnified party in connection with 
     investigation or defending any such action or claim.  Notwithstanding the
     provisions of this subsection (d), no Underwriter shall be required to 
     contribute any amount in excess of the amount by which the total price at
     which the Certificates underwritten by it and distributed to the public 
     were sold to the public exceeds the amount of any damages which such 
     Underwriter has otherwise been required to pay by reason of such untrue
     or alleged untrue statement or omission or alleged omission.  No person 
     guilty of fraudulent misrepresentation (within the meaning of Section 11(f)
     of the 1933 Act) shall be entitled to contribution from any person who was
     not guilty of such fraudulent misrepresentation. The obligations of the 
     Underwriters to contribute pursuant to this subsection (d) are several in
     proportion to their respective underwriting obligations with respect to 
     such Certificates and not joint.

     SECTION 7.  REPRESENTATIONS, WARRANTIES, AND AGREEMENTS TO SURVIVE
DELIVERY.  All representations, warranties and agreements contained in this
Agreement, or contained in certificates of officers of the Company submitted
pursuant hereto, shall remain operative and in full force and effect, regardless
of any termination of this Agreement, or the applicable Terms Agreement or any
investigation made by or on behalf of the Underwriters or any controlling person
thereof, or by or on behalf of the Company, its officers or directors and shall
survive delivery of any Certificates to the Underwriters.

     SECTION 8.  TERMINATION OF AGREEMENT.  This Agreement may be terminated for
any reason at any time by either the Company or you upon the giving of thirty
days' notice of such termination to the other party hereto; provided, however,
that if a Terms Agreement has been entered into with respect to a particular
transaction, this Agreement and the Terms Agreement may not be terminated in the
manner set forth in this sentence with respect to such particular transaction. 
You, as Representative of the Underwriters named in any Terms Agreement may also
terminate such Terms Agreement, immediately upon notice to the Company, at any
time at or prior to the applicable Closing Time (i) if there has been, since the
date of such Terms Agreement or since the respective dates as of which
information is given in the Registration Statement or Prospectus, any change, or
any development involving a prospective change, in or affecting the condition,
financial or otherwise, earnings, affairs or business of the Company or Standard
Federal, whether or not arising in the ordinary course of business, which in
your judgment would materially impair the market for, or the investment quality
of, the Certificates, or (ii) if there has occurred any material outbreak or
escalation of hostilities or other calamity or crisis the effect of which on the
financial markets of the United States is such as to make it, in your reasonable
judgment, impracticable to market the Certificates or enforce contracts for the
sale of the Certificates, or (iii) if trading in securities generally on either
the New York Stock Exchange or the American Stock Exchange has been suspended or
materially limited or any setting of minimum prices shall have been established
or (iv) if a general moratorium of commercial banking activities has been
declared by either Federal or New York State authorities.  In the event of any
such termination, (A) the covenants set forth in Section 

                              -21-

<PAGE>

3 with respect to any offering of Certificates shall remain in effect so long 
as the Underwriters own any such Certificates purchased from the Company 
pursuant to the applicable Terms Agreement and (B) the covenant set forth in 
Section 3(c), the provisions of Section 5, the indemnity agreement and 
contribution provisions set forth in Section 6, and the provisions of 
Sections 7 and 12 shall remain in effect.

     SECTION 9.  DEFAULT BY ONE OR MORE OF THE UNDERWRITERS.

          (a)  If one or more of the Underwriters participating in an offering
     of Certificates shall fail at the applicable Closing Time to purchase the
     Certificates which it or they are obligated to purchase hereunder and under
     the applicable Terms Agreement (the "Defaulted Certificates"), then such of
     you as are named therein shall arrange for you or another party or other
     parties to purchase the Defaulted Certificates upon the terms contained
     herein.  If within thirty-six hours after such default by any Underwriter
     you do not arrange for the purchase of such Defaulted Certificates, then
     the Company shall be entitled to a further period of thirty-six hours
     within which to procure another party or other parties reasonably
     satisfactory to you to purchase such Defaulted Certificates on the terms
     contained herein.  In the event that, within the respective prescribed
     periods, you notify the Company that you have so arranged for the purchase
     of such Defaulted Certificates, or the Company notifies you that it has so
     arranged for the purchase of such Defaulted Certificates, you or the
     Company shall have the right to postpone the Closing Time for a period of
     not more than seven days, in order to effect whatever changes may thereby
     be made necessary in the Registration Statement or the Prospectus, or in
     any other documents or arrangements, and the Company agrees to file
     promptly any amendments to the Registration Statement or the Prospectus
     which in your opinion may thereby be made reasonably necessary.  The term
     "Underwriter" as used in this Agreement shall include any person
     substituted under this Section with like effect as if such person had
     originally been party to this Agreement with respect to the Certificate.

          (b)  If, after giving effect to any arrangements for the purchase of
     Defaulted Certificates of a defaulting Underwriter or Underwriters by you
     and the Company as provided in subsection (a) above, the aggregate
     principal amount of such Defaulted Certificates which remains unpurchased
     does not exceed 10% of the aggregate principal amount of the Certificates
     to be purchased pursuant to the applicable Terms Agreement, then the
     Company shall have the right to require each non-defaulting Underwriter to
     purchase the principal amount of Certificates which such Underwriter agreed
     to purchase hereunder and, in addition, to require each non-defaulting
     Underwriter to purchase its pro rata share (based on the principal amount
     of Certificates which such Underwriter agreed to purchase pursuant to the
     applicable Terms Agreement) of the Defaulted Certificates of the defaulting
     Underwriter or Underwriters for which such arrangements have not been made;
     but nothing herein shall relieve a defaulting Underwriter from liability
     for its default.

          (c)  If, after giving effect to any arrangements for the purchase of
     the Defaulted Certificates of the defaulting Underwriter or Underwriters by
     you and the Company as 

                                  -22-

<PAGE>

     provided in subsection (a) above, the aggregate principal amount of such
     Defaulted Certificates which remains unpurchased exceeds 10% of the 
     aggregate principal amount of the Certificates to be purchased pursuant 
     to the applicable Terms Agreement, or if the Company shall not exercise 
     the right described in subsection (b) above to require non-defaulting 
     Underwriters to purchase Defaulted Certificates of a defaulting Underwriter
     or Underwriters, then this Agreement shall thereupon terminate, without 
     liability on the part of any non-defaulting Underwriter or the Company, 
     except for the expenses to be borne by the Company and the Underwriters as
     provided in Section 5 hereof and the indemnity agreement and contribution
     provisions in Section 6 hereof; but nothing herein shall relieve a 
     defaulting Underwriter from liability for its default.

     Brothers agrees to pay up to $500.00 to the Company  for the reasonable and
     customary costs and expenses of the Company incurred in connection with the
     filing by the Company of any Computational Materials with the Commission,

     the Commission allowing for the paper filing of Computational Materials is
     no longer available, Lehman Brothers will provide the Company with the
     Computational Materials in an electronic format.

          (f)  Lehman Brothers shall cooperate with the Company and with

     This Pooling and Servicing Agreement, dated and effective as of 
October 1, 1998 (this "Agreement"), is executed by and among ABN AMRO Mortgage 
Corporation, as depositor (the "Depositor"), LaSalle Home Mortgage 
Corporation, as servicer (the "Servicer"), and Chase Bank of Texas, National 
Association, as trustee (the "Trustee").  Capitalized terms used in this 
Agreement and not otherwise defined have the meanings ascribed to such terms 
in Article I hereof.
                                       
                             PRELIMINARY STATEMENT

     The Depositor at the Closing Date is the owner of the Loans and the 
other property being conveyed by it to the Trustee for inclusion in the Trust 
Fund. On the Closing Date, the Depositor will acquire the Certificates from 
the Trust Fund as consideration for its transfer to the Trust Fund of the 
Loans and certain other assets and will be the owner of the Certificates.  
The Depositor has duly authorized the execution and delivery of this 
Agreement to provide for the conveyance to the Trustee of the Loans and the 
issuance to the Depositor of the Certificates representing in the aggregate 
the entire beneficial ownership of the Trust Fund.  All covenants and 
agreements made by the Depositor, the Servicer and the Trustee herein with 
respect to the Loans and the other property constituting the Trust Fund are 
for the benefit of the Holders from time to time of the Certificates.  The 
Depositor and the Servicer are entering into this Agreement, and the Trustee 
is accepting the trust created hereby, for good and valuable consideration, 
the receipt and sufficiency of which are hereby acknowledged.

     The Certificates issued hereunder, other than the Class B-3, Class B-4 
and Class B-5 Certificates have been offered for sale pursuant to a 
Prospectus, dated September 18, 1998, and a Prospectus Supplement, dated 
October 22, 1998, of the Depositor (together, the "Prospectus").  The Class 
B-3, Class B-4 and Class B-5 Certificates have been offered for sale pursuant 
to a Private Placement Memorandum dated October 27, 1998.  The Trust Fund 
created hereunder is intended to be the "Trust" as described in the 
Prospectus and the Private Placement Memorandum and the Certificates are 
intended to be the "Certificates" described therein.  

     As provided herein, the Trustee will elect to treat the segregated pool 
of assets consisting of the Loans and other related assets in the Trust Fund 
subject to this Agreement as a REMIC for federal income tax purposes, and 
such segregated pool of assets will be designated as "REMIC I."  Component 
R-1 of the Class R Certificate will represent the sole class of "residual 
interests" in REMIC I for purposes of the REMIC Provisions under federal 
income tax law. 

     As provided herein, the Trustee will elect to treat the segregated pool 
of assets consisting of the REMIC I Regular Interests as a REMIC for federal 
income tax purposes, and such segregated pool of assets will be designated as 
"REMIC II".  Component R-2 of the Class R Certificate will represent the sole 
class of "residual interests" in REMIC II for purposes of the REMIC 
Provisions under federal income tax law.  The following table irrevocably 
sets forth the designations, the Remittance Rate and initial Class Principal 
Balance for each Class of Certificates which, together with the Class R-2 
Component, constitute the entire beneficial interests in REMIC II. Determined 
solely for purposes of satisfying Treasury regulation section 
1.860G-1(a)(4)(iii), the "latest possible maturity date" for each of the 
REMIC I Regular Interests and for each Class of Certificates shall be

       SUBORDINATE PRINCIPAL AMOUNT: On any Distribution Date, will be equal 
to the sum of:

       (1)    the Subordinate Percentage of the Principal Payment Amount
              (exclusive of the portion thereof attributable to the Discount
              Fractional Principal Amount);
       (2)    the Subordinate Principal Prepayment Amount; and
       (3)    the Subordinate Liquidation Amount;

       PROVIDED, HOWEVER, that the Subordinate Principal Amount shall be
       reduced by the amounts required to be distributed to the Class A-P
       Certificates with respect to the Discount Fractional Principal Shortfall
       on such Distribution Date.  

Any reduction in the Subordinate Principal Amount pursuant to the proviso 
above shall offset the amount calculated pursuant to first clause (1), second 
clause (3) and then clause (2), in each case of the definition thereof.  On 
any Distribution Date, the Subordinate Principal Amount shall be allocated 
pro rata, by Class Principal Balance, among the Classes of Subordinate 
Certificates and paid in the order of distribution to such Classes pursuant 
to clause (I)(b) of the definition of "Certificate Distribution Amount" 
herein, except as otherwise stated in such definition.  Notwithstanding the 
foregoing, on any Distribution Date prior to distributions on such date, if 
the Subordination Level for any Class of Subordinate Certificates is less 
than such percentage as of the Closing Date, the pro rata portion of the 
Subordinate Principal Prepayments Amount otherwise allocable to the Class or 
Classes junior to such Class will be distributed to the most senior Class of 
the Subordinate Certificates for which the Subordination Level is less than 
such percentage as of the Closing Date, and to the Classes of Subordinate 
Certificates senior thereto, pro rata according to the Class Principal 
Balances of such Classes.  For purposes of this definition and the definition 
of 


                                      34

"Subordination Level," the relative seniority, from highest to lowest, of the 
Classes of Subordinate Certificates shall be as follows:  Class M, Class B-1, 
Class B-2, Class B-3, Class B-4 and B-5.

       SUBORDINATE PRINCIPAL PREPAYMENT AMOUNT:  On any Distribution Date, 
the Subordinate Prepayment Percentage of the Principal Prepayment Amount for 
the Loans (exclusive of the portion thereof  attributable to the Discount 
Fractional Principal Amount (reduced by the Discount Fractional Principal 
Shortfall)).

       SUBORDINATION LEVEL:  On any specified date, with respect to any Class 
of Subordinate Certificates, the percentage obtained by dividing: (1) the sum 
of the Class Principal Balances of all Classes of Certificates which are 
subordinate in right of payment to such Class; by (2) the sum of the Class 
Principal Balances of all Classes of Certificates as of such date prior to 
giving effect to distributions or allocations of Realized Losses on the Loans 
on such date.

any transfer of the Class R Certificate, the holder of the greatest 
Percentage Interest in the Class R Certificate at year end shall be 
designated as the Tax Matters Person with respect to that year.  If the Tax 
Matters Person becomes a Disqualified Organization, the last preceding Holder

                          CONVEYANCE OF TRUST FUND;
                     ORIGINAL ISSUANCE OF CERTIFICATES

       Section 2.1.  CONVEYANCE OF TRUST FUND.  The Depositor, concurrently 
with the execution and delivery hereof, does hereby irrevocably sell, convey 
and assign to the Trustee and REMIC I 


                                      36
<PAGE>

without recourse all the right, title and interest of the Depositor in and to 
the Trust Fund and to REMIC II without recourse all the right, title and 
interest of the Depositor in and to the REMIC I Regular Interests, for the 
benefit respectively of REMIC II and the Certificateholders, including all 
interest and principal received by the Depositor with respect to the Loans 
after the Cut-Off Date (and including without limitation scheduled payments 
of principal and interest due after the Cut-Off Date but received by the 
Depositor on or before the Cut-Off Date, but not including payments of 
principal and interest due on the Loans on or before the Cut-Off Date).  The 
Depositor, at its own expense, shall file or cause to be filed protective 
Form UCC-1 financing statements with respect to the Loans in the State of 
Illinois or other applicable jurisdiction, listing itself as "Debtor" under 
such financing statement and listing the Trustee, for the benefit of the 
Certificateholders, as "Secured Party" under such financing statement.

       In connection with such assignment, the Depositor does hereby deliver 
to, and deposit with, the Trustee for the benefit of the Certificateholders 
the following documents or instruments with respect to each Loan so assigned:

              (i)    The original Mortgage Note bearing all intervening 
       endorsements endorsed, "Pay to the order of Chase Bank of Texas, 
       National Association, as Trustee, for the benefit of the 
       Certificateholders of ABN AMRO Mortgage Corporation Series 1998-4 
       Attn: Corporate Trust Department, 600 Travis Street, Houston, TX 
       77002, without recourse" and signed in the name of the Seller by an 
       Authorized Officer showing an unbroken chain of title from the 
       originator thereof to the person endorsing;
       
              (ii)   (a) The original Mortgage with evidence of recording 
       thereon, and if the Mortgage was executed pursuant to a power of 
       attorney, a certified true copy of the power of attorney certified by 
       the recorder's office, with evidence of recording thereon, or 
       certified by a title insurance company or escrow company to be a true 
       copy thereof; PROVIDED, that if such original Mortgage or power of 
       attorney cannot be delivered with evidence of recording thereon on or 
       prior to the Closing Date because of a delay caused by the public 
       recording office where such original Mortgage has been delivered for 
       recordation or because such original Mortgage has been lost, the 
       Seller shall deliver or cause to be delivered to the Purchaser (with a 
       copy to the Trustee) a true and correct copy of such Mortgage, 
       together with (1) in the case of a delay caused by the public 
       recording office, an Officer's Certificate signed by a Responsible 
       Officer of the Seller stating that such original Mortgage has been 
       dispatched to the appropriate public recording official for 
       recordation or (2) in the case of an original Mortgage that has been 
       lost, a certificate by the appropriate county recording office where 
       such Mortgage is recorded or from a title insurance company or escrow 
       company indicating that such original was lost and the copy of the 
       original mortgage is a true and correct copy;

                     (b) The original Assignment to "Chase Bank of Texas, 
       National Association, as Trustee," which assignment shall be in form 
       and substance acceptable for recording, or a copy certified by the 
       Seller as a true and correct copy of the original Assignment which has 
       been sent for recordation.  Subject to the foregoing, such assignments 
       may, if permitted by 


                                      37
<PAGE>

       law, be by blanket assignments for Loans covering Mortgaged Properties 
       situated within the same county.  If the Assignment is in blanket form,
       a copy of the Assignment shall be included in the related individual 
       Mortgage File.
       
              (iii)  The originals of any and all instruments that modify the 
       terms and conditions of the Mortgage Note, including but not limited 
       to modification, consolidation, extension and assumption agreements 
       including any adjustable rate mortgage (ARM) rider, if any;
       
              (iv)   The originals of all required intervening assignments, 
       if any, with evidence of recording thereon, and if such assignment was 
       executed pursuant to a power of attorney, a certified true copy of the 
       power of attorney certified by the recorder's office, with evidence of 
       recording thereon, or certified by a title insurance company or escrow 
       company to be a true copy thereof; PROVIDED, that if such original 
       assignment or power of attorney cannot be delivered with evidence of 
       recording thereon on or prior to the Closing Date because of a delay 
       caused by the public recording office where such original assignment 
       has been delivered for recordation or because such original Assignment 
       has been lost, the Seller shall deliver or cause to be delivered to 
       the Purchaser (with a copy to the Trustee) a true and correct copy of 
       such Assignment, together with (a) in the case of a delay caused by 
       the public recording office, an Officer's Certificate signed by a 
       Responsible Officer of the Seller stating that such original 
       assignment has been dispatched to the appropriate public recording 
       official for recordation or (b) in the case of an original assignment 
       that has been lost, a certificate by the appropriate county recording 
       office where such assignment is recorded or from a title insurance 
       company or escrow company indicating that such original was lost and 
       the copy of the original assignment is a true and correct copy;
       
              (v)    The original mortgage policy of title insurance 
       (including, if applicable, the endorsement relating to the negative 
       amortization of the Loans) or in the event such original title policy 
       is unavailable, any one of an original title binder, an original 
       preliminary title report or an original title commitment or a copy 
       thereof certified by the title company with the original policy of 
       title insurance to follow within 180 days of the Closing Date;
       
              (vi)   The mortgage insurance certificate; 
       
              (vii)  Hazard insurance certificates and copies of the hazard 
       insurance policy and, if applicable, flood insurance policy; and
       
              (viii) any and all other documents, opinions and certificates 
       executed and/or delivered by the related Mortgagor and/or its counsel 
       in connection with the origination of such Mortgage.

       If the Depositor cannot deliver the original Mortgage with evidence of 
recording thereon concurrently with the execution and delivery of this 
Agreement because of a delay caused by the public recording office where such 
original Mortgage has been delivered for recordation, the Depositor shall 
deliver to the Trustee an Officer's Certificate, with a photocopy of such 
Mortgage 


                                      38
<PAGE>

attached thereto, stating that such original Mortgage has been delivered to 
the appropriate public recording official for recordation.  The Depositor 
shall promptly deliver to the Trustee such original Mortgage with evidence of 
recording indicated thereon upon receipt thereof from the public recording 
official.

       The Depositor shall, at its own expense, promptly record or cause to 
be recorded in the appropriate public real property or other records each 
Assignment referred to in Section 2.1(ii), unless the Depositor delivers to 
the Trustee an Independent opinion of counsel admitted to practice law in the 
state in which such Mortgaged Property is located to the effect that such 
recordation is not necessary to secure the interest in the related Mortgaged 
Properties against any other transferee or creditor of the Depositor, in 
which case such Assignments shall be delivered to the Trustee for the benefit 
of the Certificateholders in recordable form.  If the Depositor cannot 
deliver the original Assignment concurrently with the execution and delivery 
of this Agreement solely because it is in the process of being prepared and 
recorded or because of a delay caused by the public recording office where 
such original Assignment has been delivered for recordation, the Depositor 
shall deliver a blanket Officer's Certificate covering all such Assignments 
stating that such original assignment is in the process of being prepared and 
recorded or it has been delivered to the appropriate public recording 
official for recordation and a photocopy of such Assignment.  Any such 
original recorded Assignment shall be delivered to the Trustee within 180 
days following the execution of this Agreement.

       If the Depositor cannot deliver the original title insurance policy 
concurrently with the execution and delivery of this Agreement, the Depositor 
shall promptly deliver each such original title insurance policy as soon as 
such policy becomes available but in no event later than 120 days following 
the execution of this Agreement.  

       All rights arising out of Loans including, without limitation, all 
funds received on or in connection with a Loan shall be held by the Depositor 
in trust for the benefit of the Certificateholders.  The Depositor shall 
maintain a complete set of books and records for each Loan which shall be 
clearly marked to reflect the ownership of each Loan by the 
Certificateholders.

       It is the express intent of this Agreement that the conveyance of the 
Loans by the Depositor to the Trustee as provided in this Section 2.1 be, and 
be construed as, a sale of the Loans by the Depositor to the Trustee and that 
the sale of the Certificates to the Certificateholders, if they are sold, be, 
and be construed as, a sale of a 100% interest in the Loans and the Trust 
Fund to such Certificateholders.  It is, further, not the intention of this 
Agreement that such conveyance be deemed a pledge of the Loans by the 
Depositor to the Trustee to secure a debt or other obligation of the 
Depositor.  However, in the event that, notwithstanding the intent of this 
Agreement, the Loans are held to be property of the Depositor, or if for any 
other reason this Agreement is held or deemed to create a security interest 
in the Loans, then (a) this Agreement shall also be deemed to be a security 
agreement within the meaning of Articles 8 and 9 of the New York Uniform 
Commercial Code; (b) the conveyance provided for in this Section 2.1 shall be 
deemed to be a grant by the Depositor to the Trustee for the benefit of the 
Certificateholders of a security interest in all of the Depositor's right, 
title and interest in and to the Loans and all amounts payable to the holders 


                                      39
<PAGE>

of the Loans in accordance with the terms thereof and all proceeds of the 
conversion, voluntary or involuntary, of the foregoing into cash, 
instruments, securities or other property, including without limitation all 
amounts, other than investment earnings, from time to time held or invested 
in the Certificate Account, whether in the form of cash, instruments, 
securities or other property; (c) the possession by the Trustee or any 
Custodian of Mortgage Notes and such other items of property as constitute 
instruments, money, negotiable documents or chattel paper shall be deemed to 
be "in possession by the secured party" for purposes of perfecting the 
security interest pursuant to Section 9-305 of the New York Uniform 
Commercial Code; and (d) notifications to persons holding such property, and 
acknowledgments, receipts or confirmations from persons holding such 
property, shall be deemed notifications to, or acknowledgments, receipts or 
confirmations from, financial intermediaries, bailees or agents (as 
applicable) of the Trustee for the benefit of the Certificateholders for the 
purpose of perfecting such security interest under applicable law (except 
that nothing in this clause (d) shall cause any person to be deemed to be an 
agent of the Trustee for any purpose other than for perfection of such 
security interest unless, and then only to the extent, expressly appointed 
and authorized by the Trustee in writing).  The Depositor and the Trustee, 
upon directions from the Depositor, shall, to the extent consistent with this 
Agreement, take such actions as may be necessary to ensure that, if this 
Agreement were deemed to create a security interest in Loans, such security 
interest would be deemed to be a perfected security interest of first 
priority under applicable law and will be maintained as such throughout the 
term of this Agreement.

       The Trustee is authorized to appoint any bank or trust company 
approved by the Depositor as Custodian of the documents or instruments 
referred to under (i) through (viii) above, and to enter into a Custodial 
Agreement for such purpose and any documents delivered thereunder shall be 
delivered to the Custodian and any Officer's Certificates delivered with 
respect thereto shall be delivered to the Trustee and the Custodian.

       Section 2.2.  ACCEPTANCE BY TRUSTEE.  The Trustee acknowledges, 
subject to the provisions of Section 2.1 and to any document exceptions 
reported pursuant to the Trustee's reviews as described below, receipt of the 
Mortgage Notes, the Mortgages, the assignments of the Mortgages and the 
Officer's Certificates referred to in Section 2.1 above, and declares that it 
holds and will hold such documents and the other documents constituting a 
part of the Mortgage Files delivered to it as Trustee in trust, upon the 
trusts herein set forth, for the use and benefit of all present and future 
Certificateholders. The Trustee acknowledges that, as of the date of the 
execution of this Agreement, the Mortgage Files have been delivered to the 
Trustee and the Trustee has conducted a preliminary review of the Mortgage 
Files.  The Trustee further acknowledges that such review included a review 
of the Mortgage Notes to determine that the appropriate Mortgage Notes have 
been delivered and endorsed in the manner set forth in Section 2.1(i).  In 
connection with such review, the Trustee shall have delivered an exceptions 
report indicating any discrepancies relating to such review.  In addition, 
the Trustee agrees, for the benefit of Certificateholders, to review each 
Mortgage File within 45 days, or with respect to assignments which must be 
recorded, within 180 days, after execution of this Agreement to ascertain 
that all required documents set forth in items (i), (ii), (v), (vi) and, to 
the extent delivered to the Trustee, items (iii), (iv), (vii) and (viii) of 
Section 2.1 have been executed and received, and that such documents relate 
to the Loans identified in Exhibit D annexed hereto, and in so doing the 
Trustee may rely on the purported due execution 


                                      40
<PAGE>


and genuineness of any such document and on the purported genuineness of any 
signature thereon.  The Trustee shall have no duty to verify or determine 
whether any Mortgage File should contain documents described in Sections 2.1 
(iii), (iv), (vii) and (viii).  The Trustee shall be under no duty or 
obligation to inspect, review or make any independent examination of any 
documents contained in each Mortgage File beyond the review specifically 
required herein.  The Trustee makes no representations as to (i) the 
validity, legality, sufficiency, enforceability or genuineness of any of the 
documents contained in each Mortgage File or any of the Loans identified on 
the Loan Schedule, or (ii) the collectability, insurability, effectiveness or 
suitability of any such Loan.  If at the conclusion of such 45-day period or 
180-day period the Trustee finds any document constituting a part of a 
Mortgage File not to have been executed or received or to be unrelated to the 
Loans identified in said Exhibit D (each such finding, a "material defect"), 
the Trustee shall promptly notify the Depositor, which shall have a period of 
90 days after such notice within which to correct or cure any such material 
defect; PROVIDED, HOWEVER, that if the Trustee shall not have received a 
document by reason of the fact that such document shall not have been 
returned by the appropriate recording office then the Depositor shall have 
until a date one year later from the Cut-Off Date to correct or cure such 
defect.  The Depositor hereby covenants and agrees that, if any such material 
defect as defined above is not corrected or cured, the Depositor will, not 
later than 90 days in the case of repurchase referred to below or not later 
than 75 days in the case of a substitution referred to below after the 
Trustee's notice to it respecting such defect either (i) repurchase the 
related Loan at a price equal to 100% of the Principal Balance of such Loan 
(or any property acquired in respect thereof) plus accrued interest on such 
Principal Balance at the applicable Pass-Through Rate to the next scheduled 
Due Date of such Loan, less any Nonrecoverable Advances made with respect to 
any such Loan or (ii) substitute for any Loan to which such material defect 
relates a different mortgage loan (a "Substitute Loan") maturing no later 
than and not more than two years earlier than the Loan being substituted for 
and having a principal balance equal to or less than and a Mortgage Interest 
Rate equal to or greater than the Mortgage Interest Rate of the Loan being 
substituted for, a Loan-to-Value Ratio equal to or less than the 
Loan-to-Value Ratio of the Loan being substituted for and otherwise having 
such characteristics so that the representations and warranties of the 
Depositor set forth in Section 2.3 hereof would not have been incorrect had 
such Substitute Loan originally been a Loan; PROVIDED, HOWEVER, that if the 
Principal Balance of the original Loan exceeds the principal balance of the 
Substitute Loan, an amount equal to that difference shall be deposited by the 
Depositor in the Certificate Account; PROVIDED, FURTHER, HOWEVER, that no 
such substitution may occur after 90 days of the Closing Date unless the 
Trustee shall have received from the Depositor an Opinion of Counsel to the 
effect that such substitution will not adversely affect the REMIC status of 
REMIC I or REMIC II or constitute a prohibited transaction or substitution 
under the REMIC provisions of the Code, and, if applicable, within the 
meaning of the REMIC Provisions of the particular State, if any, which would 
impose a tax on the Trust Fund.  Monthly Payments due with respect to 
Substitute Loans in the month of substitution are not a part of the Trust 
Fund and will be retained by the Servicer.  The Depositor shall notify the 
Rating Agency of any such substitution.  For the month of substitution, 
distributions to Certificateholders will include the Monthly Payment due on 
the Loan being substituted for in such month.  The purchase price for the 
repurchased Loan or property shall be deposited by the Depositor in the 
Certificate Account and in the case of a Substitute Loan, the Mortgage File 
relating thereto shall be delivered to the Trustee or the Custodian.  Upon 
receipt by the Trustee of written notification of such deposit signed by a 
Servicing 


                                  41
<PAGE>


Officer or the new Mortgage File, as the case may be, and an Officer's 
Certificate that such repurchase or substitution is in accordance with this 
Agreement, the Trustee shall release or cause to be released to the Depositor 
the related Mortgage File for the Loan being repurchased or substituted for, 
as the case may be, and shall execute and deliver or cause to be executed and 
delivered such instrument of transfer or assignment presented to it by the 
Depositor, in each case without recourse, as shall be necessary to transfer 
to the Depositor the Trustee's interest in such original or repurchased Loan 
or property and the Trustee shall have no further responsibility with regard 
to such Loan.  It is understood and agreed that the obligation of the 
Depositor to substitute a new Loan for or repurchase any Loan or property as 
to which such a material defect in a constituent document exists shall 
constitute the sole remedy respecting such defect available to 
Certificateholders or the Trustee on behalf of Certificateholders, but such 
obligation shall survive termination of this Agreement.  Neither the Trustee 
nor the Custodian shall be responsible for determining whether any assignment 
or mortgage delivered pursuant to Section 2.1(ii) is in recordable form or, 
if recorded, has been properly recorded.

       Section 2.3.  REPRESENTATIONS AND WARRANTIES OF THE DEPOSITOR.  The
Depositor hereby represents and warrants to the Trustee:

              (i)    that the information set forth in the Loan Schedule

       the best of the Depositor's knowledge, there is no default, breach,
       violation or event of acceleration existing under the Mortgage or the
       related Mortgage Note and no event which, with the passage of time or
       with notice and the expiration of any grace or cure period, would
       constitute a default, breach, violation or event of acceleration; and the
       Depositor has not waived any default, breach, violation or event of
       acceleration;

              (xv)   that each Loan was originated on FNMA or FHLMC uniform

              (xx)   each Loan was either (A) originated directly by or closed
       in the name of either:  (i) a savings and loan association, savings bank,
       commercial bank, credit union, insurance company, or similar institution
       which is supervised and examined by a federal or state authority or

       It is understood and agreed that the representations and warranties set
forth in this Section 2.3 shall survive delivery of the respective Mortgage
Files to the Trustee, or to a Custodian, 


                                        44
<PAGE>


as the case may be.  Upon discovery by the Depositor, Servicer, the Trustee 
or any Custodian of a breach of any of the foregoing representations and 
warranties (referred to herein as a "breach"), without regard to any 
limitation set forth in such representation or warranty concerning the 
knowledge of the Depositor as to the facts stated therein, which breach 
materially and adversely affects the interests of the Certificateholders in 
the related Loan, the party discovering such breach shall give prompt written 
notice to the others and to the Rating Agency.  

       Within 90 days of its discovery or its receipt or any Seller's receipt of
notice of breach, the Depositor shall or shall cause such Seller to cure such
breach in all material respects or shall repurchase the Loan or any property
acquired in respect thereof from the Trustee at a repurchase price equal to 100%
of the Principal Balance of such Loan plus accrued interest on such Principal
Balance at the Mortgage Interest Rate to the next scheduled Installment Due Date
of such Loan or remove such Loan from the Trust Fund and substitute in its place
a Substitute Loan or Loans with the characteristics set forth in Section 2.2
above for Substitute Loans; PROVIDED, HOWEVER, that if such breach would cause
the Loan to be other than a "qualified mortgage" as defined in Section
860G(a)(3) of the Code, any such cure, repurchase or substitution must occur
within 90 days from the date such breach was discovered; PROVIDED, FURTHER, that
no substitution (or cure which would constitute a loan modification for federal
income tax purposes) may be effected any later than two years after the Closing
Date; PROVIDED, FURTHER, that as a pre-condition to any substitution (or cure
which would constitute a loan modification for federal income tax purposes) to
be effected later than 90 days after the Closing Date (and within two years of
the Closing Date), the Trustee shall receive from the Depositor an Opinion of
Counsel to the effect that such substitution (or cure which would constitute a
loan modification for federal income tax purposes) will not adversely affect the
REMIC status of REMIC I or REMIC II or constitute a prohibited transaction under
the REMIC Provisions of the Code and, if applicable, the REMIC provisions of the
relevant State.  Except as expressly set forth herein, neither the Trustee nor
the Servicer is under any obligation to discover any breach of the above
mentioned representations and warranties.  It is understood and agreed that the
obligation of the Depositor or the Seller to repurchase or substitute any Loan
or property as to which a breach has occurred and is continuing shall constitute
the sole remedy respecting such breach available to Certificateholders or the
Trustee on behalf of Certificateholders, and such obligation shall survive as
the obligation of ABN AMRO Mortgage Corporation, the Seller or their respective
successors.

       Section 2.4.  AUTHENTICATION AND DELIVERY OF CERTIFICATES; DESIGNATION OF
CERTIFICATES AS REMIC REGULAR AND RESIDUAL INTERESTS.

              (a)    The Trustee acknowledges the transfer to the extent
       provided herein and assignment to it of the Trust Fund and, concurrently
       with such transfer and assignment, has caused to be authenticated and
       delivered to or upon the order of the Depositor, in exchange for the
       Trust Fund, Certificates evidencing the entire ownership of the Trust
       Fund.

              (b)    This Agreement shall be construed so as to carry out the
       intention of the parties that each of REMIC I and REMIC II be treated as
       a REMIC at all times prior to the date on which the Trust Fund is
       terminated.  The "regular interests" (within the meaning of Section
       860G(a)(1) of the Code) in REMIC II shall consist of the Class A
       Certificates and 


                                        45

<PAGE>

       the Subordinate Certificates.  The "residual interest" (within the 
       meaning of Section 860(G)(a)(2) of the Code) in REMIC II shall consist 
       of Component R-2 of the Class R Certificate.  The "regular interests" 
       (within the meaning of Section 860(G)(a)(1) of the Code) of REMIC I 
       shall consist of the PAC Regular Interests, the Class A-6 Regular 
       Interest, the Class A-7 Regular Interest, the Class A-8 Regular 
       Interest, the Class A-9 Regular Interest, the Class A-10 Regular 
       Interest, the Class A-11 Regular Interest, the Class A-12 Regular 
       Interest, the Class A-13 Regular Interest, the Class A-14 Regular 
       Interest, the Class A-15 Regular Interest, the Class A-16 Regular 
       Interest, the Class A-X Regular Interest, the Class A-P Regular 
       Interest, the Class M Regular Interest, the Class B-1 Regular 
       Interest, the Class B-2 Regular Interest, the Class B-3 Regular 
       Interest, the Class B-4 Regular Interest and the Class B-5 Regular 
       Interest.  (The PAC Regular Interests shall consist of four REMIC I 
       regular interests, each of which shall correspond as to principal 
       amount to one of the Class A-1, Class A-2, Class A-3 and Class A-4 
       Certificates.)  The "residual interest" (within the meaning of Section 
       860(G)(a)(2) of the Code) of REMIC I shall consist of Component R-1 of 
       the Class R Certificate.

              (c)    All payments with respect to each of the Class A-6, A-7,
       A-8, A-9, A-10, A-11, A-12, A-13, A-14, A-15, A-16, A-X, M, B-1, B-2,
       B-3, B-4 and B-5 Certificates shall be considered to have been made
       solely from the Class of Regular Interests of REMIC I having the same
       designation.  All principal payments with respect to each of the
       Class A-1, A-2, A-3  and A-4 Certificates shall be considered to have
       been made solely from the principal payments of the corresponding PAC
       Regular Interest of REMIC I.  All interest payments with respect to the
       Class A-1, A-2, A-3, A-4 and A-5 Certificates shall be considered to have
       been made solely from the PAC Regular Interests of REMIC I.

              The interest rate of each of the REMIC I Regular Interest Classes,
       A-6, A-7, A-8, A-9, A-10, A-11, A-12, A-13, A-14, A-15, A-16, A-X, M,
       B-1, B-2, B-3, B-4 and B-5 of REMIC I shall be the same as the Remittance
       Rate of the Certificate Class of REMIC II having the same designation. 

              The PAC Regular Interests shall each have an interest rate of
       6.75%.

              The principal balance of each of the Regular Interests of REMIC I
       (except the PAC Regular Interests) is equal to the principal balance of
       the Certificate of REMIC II which has the same designation. The principal
       balance of each PAC Regular Interest is equal at all times to the
       principal balance of the corresponding Class A-1, A-2, A-3 or A-4
       Certificates.  The notional principal balance of the Class A-X Regular
       Interest is equal to the Notional Amount of the Class of Certificates of
       REMIC II (i.e., the Class A-X Certificates) which has the same
       designation.  The notional principal balance of Class A-5 Certificates
       shall for purposes of the REMIC provisions be deemed to be composed of
       four component notional principal balances, each of which corresponds to
       the principal balance of a PAC Regular Interest.

       Section 2.5.  DESIGNATION OF STARTUP DAY.  The Closing Date is hereby
designated as the "startup day" of each of REMIC I and REMIC II within the
meaning of Section 860G(a)(9) of the Code.

       Section 2.6.  NO CONTRIBUTIONS.  The Trustee shall not accept or make any
contribution of cash to the Trust Fund after 90 days of the Closing Date, and
shall not accept or make any contribution of other assets to the Trust Fund
unless, in either case, it shall have received an Opinion of Counsel to the
effect that the inclusion of such assets in the Trust Fund will not cause either
REMIC I or REMIC II to fail to qualify as a REMIC at any time that any Class A
or Subordinate Certificates are outstanding or subject the Trust Fund to any tax
on contributions to the REMIC under Section 860G(d) of the Code.

       Section 2.7.  REPRESENTATIONS AND WARRANTIES OF THE SERVICER.  The
Servicer hereby represents, warrants and covenants to the Trustee for the
benefit of Certificateholders that, as of the date of execution of this
Agreement:

              (a)    the Servicer is a corporation duly formed and validly
       existing under the laws of the State of Illinois;

              (b)    the execution and delivery of this Agreement by the
       Servicer and its performance of and compliance with the terms of this
       Agreement will not violate the Servicer's corporate charter or by-laws 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 contract, agreement or other instrument to which the Servicer is
       a party or which may be applicable to the Servicer or any of its assets;

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

              (d)    the Servicer is not in default with respect to any order or
       decree of any court or any order, regulation or demand of any federal,
       state, municipal or governmental agency, which default might have
       consequences that would materially and adversely affect the condition
       (financial or other) or operations of the Servicer or its properties or
       might have consequences that would affect its performance hereunder; 

              (e)    no litigation is pending or, to the best of the Servicer's
       knowledge, threatened against the Servicer which would prohibit its
       entering into this Agreement or performing its obligations under this
       Agreement; and


                                           47
<PAGE>


              (f)    as long as the Servicer has any obligations to service the
       Loans hereunder (and it has not assigned such obligations pursuant to
       Section 3.1(c)), it shall be a FNMA or a FHLMC-qualified servicer.

       It is understood and agreed that the representations and warranties set
forth in this Section 2.7 shall survive delivery of the respective Mortgage
Files to the Trustee, or to a Custodian, as the case may be.


                                     ARTICLE III

                        ADMINISTRATION AND SERVICING OF LOANS

       Section 3.1.  SERVICER TO ACT AS SERVICER; ADMINISTRATION OF THE LOANS.

              (a)    The Servicer shall service and administer the Loans on
       behalf of the Trust Fund solely in the best interests of and for the
       benefit of the Certificateholders (as determined by the Servicer in its
       reasonable judgment) and the Trustee (as trustee for Certificateholders)
       in accordance with the terms of this Agreement and the respective Loans
       and, to the extent consistent with such terms, in the same manner in
       which, and with the same care, skill, prudence and diligence with which,
       it services and administers similar mortgage loans for other portfolios,
       giving due consideration to customary and usual standards of practice of
       prudent institutional residential mortgage lenders and loan servicers,
       and taking into account its other obligations hereunder, but without
       regard to:

                     (i)    any relationship that the Servicer, any
              sub-servicer, any special servicer or any Affiliate of the
              Servicer, any sub-servicer or any special servicer may have with
              the related Mortgagor;

                     (ii)   the ownership of any Certificate by the Servicer,
              any special servicer or any Affiliate of the Servicer, any
              sub-servicer or any special servicer;

                     (iii)  the Servicer's, any sub-servicer's or any special
              servicer's right to receive compensation for its services
              hereunder or with respect to any particular transaction; or

                     (iv)   the ownership, or servicing or management for
              others, by the Servicer, any sub-servicer or any special servicer,
              of any other mortgage loans or property.

              To the extent consistent with the foregoing and subject to any
       express limitations set forth in this Agreement, the Servicer shall seek
       to maximize the timely and complete recovery of principal and interest on
       the Mortgage Notes; PROVIDED, HOWEVER, that nothing herein contained
       shall be construed as an express or implied guarantee by the Servicer of
       the collectability of the Loans.  Subject only to the above-described
       servicing standards and the 


                                       48
<PAGE>


       terms of this Agreement and of the respective Loans, the Servicer, as 
       an independent contractor, shall service and administer the Loans and 
       shall have full power and authority, acting alone or through one or 
       more subservicers, special servicers or agents (subject to paragraph 
       (c) of this Section 3.1), to do any and all things in connection with 
       such servicing and administration which it may deem necessary or 
       desirable for the purpose of conserving the assets of the Trust Fund.  
       Without limiting the generality of the foregoing, the Servicer shall 
       and is hereby authorized and empowered by the Trustee to continue to 
       execute and deliver, on behalf of itself, the Certificateholders and 
       the Trustee or any of them, any and all financing statements, 
       continuation statements and other documents or instruments necessary 
       to maintain the lien on each Mortgaged Property and related 
       collateral; and modifications, waivers, consents or amendments to or 
       with respect to any documents contained in the related Mortgage File; 
       and any and all instruments of satisfaction or cancellation, or of 
       partial or full release or discharge and all other comparable 
       instruments, with respect to the Loans and with respect to the related 
       Mortgaged Properties.  Notwithstanding the foregoing, the Servicer 
       (whether acting alone or through one or more subservicers, special 
       servicers or agents) shall not modify, amend, waive or otherwise 
       consent to the change of the terms of any of the Loans (including 
       without limitation extending the stated maturity date of any Loan or 
       forgiving principal of or interest on any Loan), except as permitted 
       by Section 3.2 hereof.  The Servicer shall service and administer the 
       Loans in accordance with applicable law and shall provide to the 
       Mortgagors any reports required to be provided to them thereby.  To 
       enable the Servicer to carry out its servicing and administrative 
       duties hereunder, upon the Servicer's written request accompanied by 
       the forms of any documents requested, the Trustee shall execute and 
       deliver to the Servicer any powers of attorney and other documents 
       necessary or appropriate and the Trustee shall not be responsible for 
       releasing such powers of attorney.  The Trustee shall not be 
       responsible for, and the Servicer shall indemnify the Trustee for, any 
       action taken by the Servicer pursuant to the application of any such 
       power of attorney.  The relationship of the Servicer (and of any 
       successor thereto) to the Trustee under this Agreement is intended by 
       the parties to be that of an independent contractor and not that of a 
       joint venturer, partner or agent.

              (b)    The Servicer, Trustee and Depositor intend that REMIC I and
       REMIC II formed hereunder shall constitute, and that the Servicer shall
       perform its duties and obligation hereunder so as to qualify each of them
       as, a "real estate mortgage investment conduit" as defined in and in
       accordance with the REMIC Provisions.  The Tax Matters Person, or the
       Person acting as attorney-in-fact and agent therefor, shall:  (a) prepare
       and file, or cause to be prepared and filed, federal tax returns (as well
       as any other federal and state information and other returns) using a
       calendar year as the taxable year when and as required by the REMIC
       Provisions; (b) make (or cause to be made) an election, on behalf of each
       of REMIC I and REMIC II, to be treated as a REMIC on the Federal tax
       return and any applicable state or local returns for the first taxable
       year, in accordance with the REMIC Provisions; (c) prepare and forward,
       or cause to be prepared and forwarded, to the Certificateholders all
       information reports (including, without limitation, the information
       required in connection with the computation of the present value of
       anticipated excess inclusions as required by Section 1.860E-2(a)(5) of
       the REMIC Provisions) as and when required 


                                           49

       to be provided to them in accordance with the REMIC Provisions; (d) 
       conduct the affairs of the Trust Fund at all times that REMIC I  
       Regular Interests or REMIC II Certificates are outstanding so as to 
       maintain the status of each of REMIC I and REMIC II as a REMIC under 
       the REMIC Provisions; and (e) not knowingly or intentionally take any 
       action or omit to take any action that would cause the termination of 
       the REMIC status of either REMIC I or REMIC II.

              (c)    The Servicer may enter into sub-servicing agreements with
       third parties with respect to any of its respective obligations
       hereunder, PROVIDED, that (1) any such agreement shall be consistent with
       the provisions of this Agreement and (2) no sub-servicer retained by the
       Servicer shall grant any modification, waiver or amendment to any Loan
       without the approval of the Servicer.  Any such sub-servicing agreement
       may permit the sub-servicer to delegate its duties to agents or
       subcontractors so long as the related agreements or arrangements with
       such agents or subcontractors are consistent with the provisions of this
       Section 3.1(c).

              Any sub-servicing agreement entered into by the Servicer with a
       Person other than the Depositor shall provide that it may be assumed or
       terminated by the Trustee if the Trustee has assumed the duties of the
       Servicer, without cost or obligation to the assuming or terminating party
       or the Trust Fund, upon the assumption by such party of the obligations
       of the Servicer pursuant to Section 7.5.

              Any sub-servicing agreement, and any other transactions or
       services relating to the Loans involving a sub-servicer, including (if
       applicable) the Depositor in its capacity as sub-servicer under a
       sub-servicing agreement and not in its capacity as a party to this
       Agreement, shall be deemed to be between the Servicer and such
       sub-servicer (including the Depositor) alone, and the Trustee and the
       Certificateholders shall not be deemed parties thereto and shall have no
       claims, rights, obligations, duties or liabilities with respect to the
       sub-servicer, except as set forth in Section 3.1(d).

              In the event that the Trustee assumes the servicing obligations of
       the Servicer, upon request of the Trustee, the Servicer shall at its own
       expense deliver to the Trustee all documents and records relating to any
       sub-servicing agreement and the Loans then being serviced thereunder and
       an accounting of amounts collected and held by it, if any, and will
       otherwise use its best efforts to effect the orderly and efficient
       transfer of any sub-servicing agreement to the Trustee.

              (d)    Costs incurred by the Servicer in effectuating the timely
       payment of taxes and assessments on the Mortgaged Property securing a
       Mortgage Note shall be recoverable by the Servicer pursuant to
       Section 3.3.  The Servicer shall ensure all such taxes and assessments
       are timely paid.

              The Servicer, as initial servicer, shall pay all of its costs and
       proven damages incurred with respect to or arising out of any allegation
       of impropriety in its servicing of the 


                                           50

<PAGE>

       Loans.  Further, the Servicer shall not be entitled to reimbursement or 
       indemnification from either the Trust Fund or the Certificateholders 
       with respect to any such costs, claims and damages.

              (e)    Notwithstanding any sub-servicing agreement, any of the
       provisions of this Agreement relating to agreements or arrangements
       between the Servicer and any Person (including the Depositor) acting as
       sub-servicer (or its agents or subcontractors) or any reference to
       actions taken through any Person (including the Depositor) acting as
       sub-servicer or otherwise, the Servicer shall remain obligated and
       primarily liable to the Trustee and Certificateholders for the servicing
       and administering of the Loans in accordance with the provisions of this
       Agreement without diminution of such obligation or liability by virtue of
       such sub-servicing agreements or arrangements or by virtue of
       indemnification from the Depositor or any other Person acting as
       sub-servicer (or its agents or subcontractors) to the same extent and
       under the same terms and conditions as if the Servicer alone were
       servicing and administering the Loans.  The Servicer shall be entitled to
       enter into an agreement with any sub-servicer providing for
       indemnification of the Servicer by such sub-servicer (including the
       Depositor), and nothing contained in this Agreement shall be deemed to
       limit or modify such indemnification, but no such agreement for
       indemnification shall be deemed to limit or modify this Agreement.

       Section 3.2.  COLLECTION OF CERTAIN LOAN PAYMENTS; CERTIFICATE ACCOUNT.

              (a)    The Servicer shall make reasonable efforts to collect all
       payments called for under the terms and provisions of the Loans, and
       shall, to the extent such procedures shall be consistent with this
       Agreement, follow such collection procedures as it follows with respect
       to conventional mortgage loans it services for itself and any of its
       Affiliates; PROVIDED, HOWEVER, that the Servicer agrees not to permit any
       modification with respect to any Loan that would change the manner in
       which the Mortgage Interest Rate is computed, forgive any principal or
       interest or change the term of such Loan.  Consistent with the foregoing,
       the Servicer may in its discretion (i) waive any assumption fee, late
       payment charge or other charge in connection with a Loan, and
       (ii) arrange a schedule, running for no more than 180 days after the
       scheduled Due Date, for payment of any installment on any Mortgage Note
       or after the due date of any other payment due under the related Mortgage
       Note for the liquidation of delinquent items, PROVIDED, that the Servicer
       shall continue to be obligated to make Advances in accordance with
       Section 4.3 during the continuance of such period.  With respect to any
       Loans which provide for the right of the holder thereof to call for early
       repayment thereof at times specified therein, neither the Trustee nor the
       Servicer shall exercise any such right, except that the Trustee shall
       exercise such right at the written direction of the Servicer set forth in
       an Officer's Certificate in connection with a default under the related
       Note.  Notwithstanding anything herein to the contrary, neither the
       Servicer nor any other party may take any action that would cause a
       "significant modification" of any Loan within the meaning of the REMIC
       Provisions that would cause REMIC I or REMIC II to fail to qualify as a
       REMIC at any time or cause a tax to be imposed on the Trust Fund under
       the REMIC Provisions.



                                     51

              (b)    The Servicer shall establish and maintain a separate
       account as set forth in Article I (the "Custodial Account for P&I"), and
       shall on the Closing Date credit any amounts representing scheduled
       payments of principal and interest due after the Cut-off Date but
       received by the Servicer on or before the Closing Date, and thereafter on
       a daily basis the following payments and collections received or made by
       it (other than in respect of principal of and interest on the Loans due
       on or before the Cut-off Date):

                     (i)    All Mortgagor payments on account of principal,
              including Principal Prepayments on the Loans;

                     (ii)   All Mortgagor payments on account of interest on the
              Loans, which may be net of that portion thereof which the Servicer
              is entitled to retain as Servicing Fees (adjusted for any amounts
              related to Compensating Interest) pursuant to Section 3.9, as
              adjusted pursuant to Section 4.6;

                     (iii)  All net Liquidation Proceeds;

                     (iv)   All Insurance Proceeds received by the Servicer,
              other than proceeds to be applied to the restoration or repair of
              the property subject to the related Mortgage or released to the
              Mortgagor in accordance with the Servicer's normal servicing
              procedures, and all amounts deposited by the Servicer with respect
              to the failure to maintain flood or fire and hazard insurance
              policies, pursuant to Section 3.5;

                     (v)    All Advances made by the Servicer pursuant to
              Section 4.3;

                     (vi)   All repurchase proceeds from the repurchase of a
              Loan pursuant to a Purchase Obligation;

                     (vii)  any amounts required to be deposited pursuant to
              Section 3.2(c) in connection with net losses realized on Eligible
              Investments with respect to funds held in the Custodial Account
              for P&I;

                     (viii) all income and gain realized from any investment of
              the funds in the Custodial Account for P&I in Eligible
              Investments;

                     (ix)   all net income from the renting of REO Property
              pursuant to Section 3.7(c); and

                     (x)    All other amounts required to be deposited in the
              Custodial Account for P&I pursuant to this Agreement.




                                     52
<PAGE>

              (c)    The Servicer may invest the funds in the Custodial Account
       for P&I in Eligible Investments which shall mature not later than the
       second Business Day preceding the next Distribution Date unless the
       Custodial Account for P&I is maintained with the Trustee in which case
       they may mature one Business Day prior to the Distribution Date.  The
       Eligible Investments may not be sold or disposed of prior to their
       maturity.  All such Eligible Investments shall be made in the name of the
       Servicer (in its capacity as such) or its nominee.  All income and gain
       realized from any such investment shall be for the benefit of the
       Servicer, and shall be payable to the Servicer.  The amount of any losses
       incurred in respect of any such investments shall be deposited in the
       Custodial Account for P&I by the Servicer, out of its own funds
       immediately as realized without right to reimbursement therefor.

              (d)    The foregoing requirements for deposit in the Custodial
       Account for P&I shall be exclusive, it being understood and agreed that,
       without limiting the generality of the foregoing, payments in the nature
       of those described in the last paragraph of this Section 3.2 and payments
       in the nature of late payment charges or assumption fees need not be
       deposited by the Servicer in the Custodial Account for P&I.  All funds
       deposited by the Servicer in the Custodial Account for P&I shall be held
       by it in trust in the Custodial Account for P&I until disbursed in
       accordance with Section 4.1 or withdrawn in accordance with Section 3.3;
       PROVIDED, HOWEVER, that the Servicer shall withdraw such funds and
       deposit them in such manner as to not result in a downgrading or
       withdrawal of the rating then assigned to the Certificates by the Rating
       Agency.  If the Servicer deposits in the Custodial Account for P&I any
       amount not required to be deposited therein, it may at any time withdraw
       such amount from the Custodial Account for P&I pursuant to Section 3.3(i)
       of this Agreement.

       Certain of the Loans may provide for payment by the Mortgagor of amounts
to be used for payment of taxes, assessments, hazard or other insurance premiums
or comparable items for the account of the Mortgagor.  The Servicer may deal
with these amounts in accordance with its normal servicing procedures.

       Section 3.3.  PERMITTED WITHDRAWALS FROM THE CUSTODIAL ACCOUNT FOR P&I. 
The Servicer may, from time to time, make withdrawals from the Custodial Account
for P&I for the following purposes:

              (a)    to reimburse itself for Advances made by it pursuant to
       Section 3.4 or 4.3, the Servicer's right to reimburse itself pursuant to
       this subclause (a) being limited to amounts received on or in respect of
       particular Loans (including, for this purpose, Liquidation Proceeds and
       Insurance Proceeds which represent late recoveries of payments of
       principal and/or interest respecting which any such Advance was made and
       any net income received from the renting of REO Property pursuant to
       Section 3.7(c)) or to reimburse itself for Advances from funds in the
       Custodial Account for P&I held for future distribution or withdrawal,
       such funds to be replaced by the Servicer to the extent that funds in the
       Custodial Account for P&I on a future Withdrawal Date are less than the
       payment required to be made to the Certificate Account therefrom as of
       such future Distribution Date;



                                     53
<PAGE>

              (b)    (i) to reimburse itself from Liquidation Proceeds for
       Liquidation Expenses, (ii) for amounts expended by it pursuant to
       Section 3.7 in good faith in connection with the restoration of damaged
       property and (iii) to the extent that Liquidation Proceeds after such
       reimbursement are in excess of the Principal Balance of the related Loan
       together with accrued and unpaid interest thereon at the applicable
       Pass-Through Rate to the date of such liquidation, net of any related
       Advances which were unreimbursed prior to the receipt of such Liquidation
       Proceeds, to pay to itself any unpaid Servicing Fees, and any assumption
       fees, late payment charges or other Mortgage charges on the related Loan;

              (c)    to pay to itself from any Mortgagor payment as to interest
       or other recovery with respect to a particular Loan, to the extent
       permitted by this Agreement, that portion of any payment as to interest
       in excess of interest at the applicable Pass-Through Rate which the
       Servicer is entitled to retain as Servicing Fees pursuant to Section 3.9
       or otherwise;

              (d)    to reimburse itself for expenses incurred by and
       recoverable by or reimbursable to it pursuant to Section 3.1 or 3.5 after
       the related Mortgagor has reimbursed the Trust Fund for such expenses or
       following liquidation of the related Loan, or pursuant to Section 6.3; 

              (e)    to pay to itself with respect to each Loan or property
       acquired in respect thereof that has been repurchased pursuant to
       Section 2.2 or 2.3 or purchased by the Class R Certificateholder pursuant
       to Section 9.1 all amounts received thereon and not distributed as of the
       date on which the related Principal Balance is determined;

              (f)    to reimburse itself for any Nonrecoverable Advances;

              (g)    to disburse to the Trustee in order that the Trustee may
       make payments to Certificateholders in the amounts and in the manner
       provided for in Section 4.1;

              (h)    to pay itself any net interest or other income earned and
       received on or investment income received with respect to funds in the
       Custodial Account for P&I; and

              (i)    to make payments to itself or others pursuant to any
       provision of this Agreement and to remove any amounts not required to be
       deposited therein and to clear and terminate the Custodial Account for
       P&I pursuant to Section 9.1.

       Since in connection with withdrawals pursuant to subclauses (a), (b), 
(c) and (e) the Servicer's entitlement thereto is limited to collections or 
other recoveries on the related Loan, the Servicer shall keep and maintain a 
separate accounting for each Loan for the purpose of justifying any 
withdrawal from the Custodial Account for P&I pursuant to such subclauses.




                                     54
<PAGE>

       The Servicer shall make the withdrawal referred to in subclause (g)
above and shall deposit the amount so withdrawn into the Certificate Account
prior to 4:00 P.M. New York City time on each related Withdrawal Date.

       Section 3.4.  TAXES, ASSESSMENTS AND SIMILAR ITEMS.  With respect to each
Loan, the Servicer shall maintain accurate records with respect to each related
Mortgaged Property reflecting the status of taxes, assessments and other similar
items that are or may become a lien on the related Mortgaged Property and the
status of insurance premiums payable with respect thereto.  The Servicer shall
require that payments for taxes, assessments, insurance premiums and other
similar items be made by the Mortgagor at the time they first become due.  If a
Mortgagor fails to make any such payment on a timely basis, the Servicer shall
advance the amount of any shortfall unless the Servicer determines in its good
faith judgment that such advance would not be ultimately recoverable from future
payments and collections on the related Loan (including without limitation
Insurance Proceeds and Liquidation Proceeds), or otherwise.  The Servicer shall
be entitled to reimbursement of advances it makes pursuant to the preceding
sentence, together with interest thereon at the Prime Rate, from amounts
received on or in respect of the related Loan respecting which such advance was
made or if such advance has become nonrecoverable, in either case to the extent
permitted by Section 3.3 of this Agreement.  No costs incurred by the Servicer
in effecting the payment of taxes and assessments on the Mortgaged Properties
shall, for the purpose of calculating distributions to Certificateholders, be
added to the amount owing under the related Loans, notwithstanding that the
terms of such Loans so permit.

       Section 3.5.  MAINTENANCE OF INSURANCE.  The Servicer shall also cause to
be maintained for each Loan fire and hazard insurance with extended coverage as
is customary in the area where the Mortgaged Property is located in an amount
which is at least equal to the lesser of (i) the Principal Balance of such Loan
or (ii) the replacement value costs of improvements securing such Loan.  The
Servicer shall cause to be maintained fire and hazard insurance with extended
coverage on each REO Property in an amount which is at least equal to the
greater of (i) an amount not less than is necessary to avoid the application of
any co-insurance clause contained in the related fire and hazard insurance
policy or (ii) the replacement cost of the improvements which are a part of such
property.  The Servicer shall also cause to be maintained for each Loan with a
Loan-to-Value Ratio greater than 80% a primary mortgage insurance policy which
will cover at least 75% of the original fair market value of the related
Mortgaged Property until such time as the principal balance of such Loan is
reduced to 80% of the current fair market value or otherwise in accordance with
applicable law.  The Servicer on behalf of the Trustee as Mortgagee shall
maintain or cause the related Mortgagor to maintain for each Loan such other
insurance on the related Mortgaged Property as may be required by the terms of
the related Mortgage Note.  If the Mortgaged Property is in an area identified
in the Federal Register by the Flood Emergency Management Agency as having
special flood hazards the Servicer will cause to be maintained a flood insurance
policy meeting the requirements of the current guidelines of the Federal
Insurance Administration with a generally acceptable insurance carrier, in an
amount representing coverage not less than the least of (i) the full insurable
value, (ii) the maximum amount of insurance which is available under the Flood
Disaster Protection Act of 1973, and (iii) the Principal Balance of the related
Loan.  The Servicer shall also maintain fire and hazard insurance with extended
coverage and, if applicable, flood insurance on 



                                     55

<PAGE>

property acquired upon foreclosure, or by deed in lieu of foreclosure, of any 
Loan in an amount that is at least equal to the lesser of (i) the maximum 
insurable value of the improvements which are a part of such property and 
(ii) the principal balance owing on such Loan at the time of such foreclosure 
or grant of deed in lieu of foreclosure plus accrued interest and related 
Liquidation Expenses.  If an REO Property was located at the time of 
origination of the related Loan in a federally designated special flood 
hazard area, the Servicer will obtain flood insurance in respect thereof 
providing substantially the same coverage as described in the preceding 
sentence.  If at any time during the term of this Agreement a recovery under 
a flood or fire and hazard insurance policy in respect of an REO Property is 
not available but would have been available if such insurance were maintained 
thereon in accordance with the standards applied to Mortgaged Properties 
described herein, the Servicer shall either (i) immediately deposit into the 
Custodial Account for P&I from its own funds the amount that would have been 
recovered or (ii) apply to the restoration and repair of the property from 
its own funds the amount that would have been recovered, if such application 
would be consistent with the servicing standard set forth in Section 3.1.  It 
is understood and agreed that such insurance shall be with insurers approved 
by the Servicer and that no earthquake or other additional insurance is to be 
required of any Mortgagor, other than pursuant to such applicable laws and 
regulations or policies of the Servicer as shall at any time be in force and 
as shall require such additional insurance.  Pursuant to Section 3.2, any 
amounts collected by the Servicer under any insurance policies maintained 
pursuant to this Section 3.5 (other than amounts to be applied to the 
restoration or repair of the property subject to the related Mortgage or 
released to the Mortgagor in accordance with the Servicer's normal servicing 
procedures) shall be deposited into the Custodial Account for P&I, subject to 
withdrawal pursuant to Section 3.3.  Any cost incurred by the Servicer in 
maintaining any such insurance shall be recoverable by the Servicer pursuant 
to Section 3.3.  In the event that the Servicer shall obtain and maintain a 
blanket policy issued by an insurer that qualifies under the guidelines set 
forth for the Servicer by FNMA or FHLMC, insuring against hazard losses on 
all of the Loans, then, to the extent such policy provides coverage in an 
amount equal to the unpaid principal balance on the Loans without 
co-insurance and otherwise complies with all other requirements set forth in 
the first paragraph of this Section 3.5, it shall conclusively be deemed to 
have satisfied its obligation as set forth in such first paragraph, it being 
understood and agreed that such policy may contain a deductible clause, in 
which case the Servicer shall, in the event that there shall not have been 
maintained on the related mortgaged or acquired property an insurance policy 
complying with the first paragraph of this Section 3.5 and there shall have 
been a loss which would have been covered by such a policy had it been 
maintained, be required to deposit from its own funds into the Custodial 
Account for P&I or apply to the restoration of the property the amount not 
otherwise payable under the blanket policy because of such deductible clause.

       The Servicer shall obtain and maintain at its own expense throughout 
the term of this Agreement a blanket fidelity bond and an errors and 
omissions insurance policy with broad coverage with responsible companies 
covering the Servicer's officers and employees and other persons acting on 
behalf of the Servicer in connection with its activities under this 
Agreement.  Any such fidelity bond and errors and omissions insurance shall 
provide an amount of coverage and will maintain such coverage at a level 
which will permit the Servicer to continue to be a FNMA or a FHLMC-qualified 
Servicer and shall protect and insure the Servicer against losses, including 
forgery, theft, embezzlement, fraud, errors and omissions and negligent acts 
of such persons. No provision of this 



                                     56
<PAGE>

Section 3.5 requiring such fidelity bond and errors and omissions insurance 
shall diminish or relieve the Servicer from its duties and obligations as set 
forth in this Agreement.

       Section 3.6.  ENFORCEMENT OF DUE-ON-SALE CLAUSES; ASSUMPTION AND
SUBSTITUTION AGREEMENTS.  In any case in which property subject to a Mortgage is
conveyed by the Mortgagor, the Servicer reserves the right to enforce any
due-on-sale clause contained in the related Mortgage Note or Mortgage, to the
extent permitted under applicable law and governmental regulations, but only to
the extent that such enforcement will not adversely affect or jeopardize
coverage under any related insurance policy or result in legal action by the
Mortgagor.  Subject to the foregoing, the Servicer is authorized to take or
enter into an assumption or substitution agreement from or with the Person to
whom such property has been or is about to be conveyed.  The Servicer is also
authorized to release the original Mortgagor from liability upon the Loan and
substitute the new Mortgagor as obligor thereon.  In connection with such
assumption or substitution, the Servicer shall apply such underwriting standards
and follow such practices and procedures as shall be normal and usual and as it
applies to mortgage loans owned solely by it or any of its Affiliates.  The
Servicer shall notify the Trustee that any such assumption or substitution
agreement has been completed by forwarding to the Trustee the original copy of
such assumption or substitution agreement, which copy shall be added by the
Trustee to the related Mortgage File and shall, for all purposes, be considered
a part of such Mortgage File to the same extent as all other documents and
instruments constituting a part thereof.  In connection with any such assumption
or substitution agreement, the interest rate of the related Mortgage Note shall
not be changed.  Any fee collected by the Servicer for entering into an
assumption or substitution of liability agreement will be retained by the
Servicer as servicing compensation.

       Notwithstanding the foregoing paragraph or any other provision of this
Agreement, the Servicer shall not be deemed to be in default, breach or any
other violation of its obligations hereunder by reason of any conveyance by the
Mortgagor of the Mortgaged Property or any assumption of a Loan by operation of
law which the Servicer in good faith determines it may be restricted by law from
preventing, for any reason whatsoever.

       Section 3.7.  REALIZATION UPON DEFAULTED LOANS.

              (a)    Consistent with the servicing standard set forth in Section
       3.1 and with a view to the best economic interest of the Trust Fund, the
       Servicer shall foreclose upon or otherwise comparably convert (which may
       include acquisition of an REO Property) the Mortgaged Properties securing
       such of the Loans as come into and continue in default and as to which no
       satisfactory arrangements can be made for collection of delinquent
       payments pursuant to Section 3.2.  In connection with such foreclosure or
       other conversion, the Servicer shall follow such practices and procedures
       as it shall deem necessary or advisable and as shall be normal and usual
       in its general mortgage servicing activities.  The foregoing is subject
       to the proviso that the Servicer shall not be required to expend its own
       funds in connection with any foreclosure or to restore any damaged
       property unless it shall determine (i) that such foreclosure and/or
       restoration will increase the Liquidation Proceeds to Certificateholders
       after reimbursement to itself for such expenses and (ii) that such
       expenses 



                                     57
<PAGE>

       will be recoverable to it through Liquidation Proceeds (respecting 
       which it shall have priority for purposes of withdrawal from the 
       Custodial Account for P&I pursuant to Section 3.3).  Any gain on 
       foreclosure or other conversion of a Liquidated Loan shall be 
       distributed to the Class R Certificateholder.  The Servicer shall be 
       responsible for all other costs and expenses incurred by it in any 
       such proceedings; PROVIDED, HOWEVER, that it shall be entitled to 
       reimbursement thereof (as well as any Servicing Fees and other amounts 
       due it, if any), to the extent, but only to the extent, that 
       withdrawals from the Custodial Account for P&I with respect thereto 
       are permitted under Section 3.3. Within 30 days after receipt of 
       Liquidation Proceeds in respect of a Liquidated Loan, the Servicer 
       shall provide to the Trustee a statement of accounting for the related 
       Liquidated Loan, including without limitation (i) the Loan number, 
       (ii) the date the Loan was acquired in foreclosure or deed in lieu, 
       and the date the Loan became a Liquidated Loan, (iii) the gross sales 
       price and the related selling and other expenses, (iv) accrued 
       interest calculated from the foreclosure date to the liquidation date, 
       and (v) such other information as the Trustee may reasonably specify.

              (b)    Prior to any such foreclosure, the Servicer may, at its
       option, repurchase any Loan which is 90 days or more delinquent and which
       the Servicer determines in good faith would otherwise become subject to
       foreclosure proceedings or any Loan as to which the Mortgagor tenders a
       deed in lieu of foreclosure at a price equal to the outstanding Principal
       Balance of the Loan plus accrued interest at the applicable Pass-Through
       Rate to the next Due Date.  Any such repurchase shall be deemed a
       Principal Prepayment for purposes of this Agreement and all amounts in
       respect thereof shall be deposited into the Custodial Account for P&I
       pursuant to Section 3.2(b).

              (c)    The Trust Fund shall not acquire any real property (or
       personal property incident to such real property) except in connection
       with a default or imminent default of a Loan. Based on a report prepared
       by an Independent Person who regularly conducts environmental audits that
       the Mortgaged Property for which foreclosure proceedings are contemplated
       is in compliance with applicable environmental laws, and there are no
       circumstances present at such Mortgaged Property relating to the use,
       management or disposal of any hazardous materials, wastes, or petroleum
       based materials for which investigation, testing, monitoring,
       containment, clean-up or remediation could be required under any federal,
       state or local law or that it would be in the best economic interest of
       the Trust Fund to acquire title to such Mortgaged Property and further to
       take such actions as would be necessary and appropriate to effect such
       compliance and/or respond to such circumstances, the Servicer will not
       conduct such foreclosure proceedings. If the Servicer otherwise becomes
       aware, under its customary servicing procedures, of an environmental
       hazard with respect to a Loan for which foreclosure proceedings are
       contemplated, the Servicer will not conduct such foreclosure proceedings
       unless it determines in good faith that the liability associated with the
       environmental hazard will be less than the Liquidation Proceeds to be
       realized from the sale of the related Mortgaged Property.  In the event
       that the Trust Fund acquires any real property (or personal property
       incident to such real property) in connection with a default or imminent
       default of a Loan, such REO Property shall be disposed of by the Trust
       Fund within three years after its acquisition by the Trust 



                                     58
<PAGE>

       Fund unless the Trustee shall have received from the Servicer an 
       Opinion of Counsel to the effect that the holding by the Trust Fund of 
       such REO Property subsequent to three years after its acquisition will 
       not cause either REMIC I or REMIC II to fail to qualify as a REMIC 
       under the REMIC Provisions at any time that any REMIC I Regular 
       Interests or Certificates are outstanding, in which case such REO 
       Property shall be disposed of as soon as possible by the Trust Fund 
       but in no event shall be held longer than the maximum period of time 
       during which the Trust Fund is then permitted to hold such REO 
       Property and allow REMIC I and REMIC II to remain qualified as REMICs 
       under the REMIC Provisions.  The Servicer shall manage, conserve, 
       protect and operate each such REO Property for the Certificateholders 
       solely for the purpose of its prompt disposition and sale in a manner 
       which does not cause such REO Property to fail to qualify as 
       "foreclosure property" within the meaning of Section 860G(a)(8) of the 
       Code.  Pursuant to its efforts to sell such REO Property, the Servicer 
       shall either itself or through an agent selected by the Servicer 
       protect and conserve such REO Property in the same manner and to such 
       extent as is customary in the locality where such property is located 
       and may, incident to its conservation and protection of the interests 
       of the Certificateholders, rent the same, or any part thereof, as the 
       Servicer deems to be in the best interest of the Servicer and the 
       Certificateholders for the period prior to the sale of such REO 
       Property. All proceeds from the renting of such REO Property shall, 
       net of any costs or expenses of the Servicer in connection therewith, 
       be deposited into the Custodial Account for P&I pursuant to Section 
       3.3(b)(ix).

              (d)    In the event that title to any Mortgaged Property is
       acquired in foreclosure or by deed in lieu of foreclosure, the deed or
       certificate of sale shall be issued to the Trustee, or to its nominee on
       behalf of Certificateholders.  Notwithstanding any such acquisition of
       title and cancellation of the related Loan, such Loan shall (except for
       purposes of Section 9.1) be considered to be a Loan held in the Trust
       Fund until such time as the related REO Property shall be sold by the
       Trust Fund and shall be reduced only by collections net of expenses. 
       Consistent with the foregoing, for purposes of all calculations
       hereunder, so long as such Loan shall be considered to be an outstanding
       Loan, it shall be assumed that, notwithstanding that the indebtedness
       evidenced by the related Mortgage Note shall have been discharged, such
       Mortgage Note and, for purposes of determining the Scheduled Principal
       Balance thereof, the related amortization schedule in effect at the time
       of any such acquisition of title remain in effect.

              (e)    The Servicer shall not acquire for the benefit of the Trust
       Fund any personal property pursuant to this Section 3.7 unless either:

                     (i)    such personal property is incident to real property
              (within the meaning of Section 856(e)(1) of the Code) so acquired
              by the Servicer for the benefit of the Trust Fund; or

                     (ii)   the Servicer shall have requested and received an
              Opinion of Counsel (which opinion shall be an expense of the Trust
              Fund) to the effect that the holding of such personal property by
              the Trust Fund will not cause the imposition of a tax on 



                                     59
<PAGE>

              the Trust Fund under the REMIC Provisions or cause either REMIC 
              I or REMIC II of the Trust Fund to fail to qualify as a REMIC 
              at any time that any Certificate is outstanding.
              
       Section 3.8.  TRUSTEE TO COOPERATE; RELEASE OF MORTGAGE FILES.  Upon the
payment in full of any Loan, or the receipt by the Servicer of a notification
that the payment in full will be escrowed in a manner customary for such
purposes, the Servicer will immediately notify the Trustee by an Officer's
Certificate (which Officer's Certificate shall include a statement to the effect
that all amounts received in connection with such payment which are required to
be deposited in the Custodial Account for P&I pursuant to Section 3.2 have been
or will be so deposited) and shall by such Officer's Certificate request
delivery to it of the Mortgage File.  Upon receipt of such Officer's Certificate
and request, the Trustee shall promptly release or cause to be released the
related Mortgage File to the Servicer.  From time to time and as appropriate for
the servicing or foreclosure of any Loan, the Trustee shall, upon written
request of the Servicer and delivery to the Trustee of a trust receipt signed by
a Servicing Officer, release or cause to be released the related Mortgage File
to the Servicer and shall execute such documents furnished to it as shall be
necessary to the prosecution of any such proceedings.  Such trust receipt shall
obligate the Servicer to return each and every document previously requested
from the Mortgage File to the Trustee when the need therefor by the Servicer no
longer exists unless the Loan shall be liquidated, in which case, upon receipt
of a certificate of a Servicing Officer similar to that hereinabove specified,
the trust receipt shall be released by the Trustee to the Servicer by delivery
to a Servicing Officer and the Trustee shall have no further responsibility with
respect to such Mortgage Files.

       Section 3.9.  SERVICING COMPENSATION.  The Servicer shall be entitled to
retain or, if not retained, to withdraw from the Certificate Account as
servicing compensation its Servicing Fee out of each payment on account of
interest on each Loan, subject to adjustment as provided in Section 4.6.  The
Servicer shall also be entitled to payment of unpaid Servicing Fees with respect
to a delinquent Loan out of Liquidation Proceeds with respect to such Loan, to
the extent permitted by Section 3.3(b).  Servicing compensation in the form of
assumption fees, late payment charges or otherwise shall be retained by the
Servicer and need not be deposited in the Custodial Account for P&I.  The
Servicer shall also be entitled to additional servicing compensation out of
Liquidation Proceeds to the extent provided in Section 3.3(b).  The Servicer
shall be required to pay all expenses incurred by it in connection with its
servicing activities hereunder (including maintenance of the blanket hazard
insurance policy and the blanket fidelity bond and errors and omissions policy
required by Section 3.5) and shall not be entitled to reimbursement therefor
except as specifically provided in Sections 3.1, 3.3, 3.5 and 3.7.

       On each Distribution Date, the Servicer shall pay to the Certificate
Administrator and the Trustee the Certificate Administration and Trustee Fee out
of the Servicing Fee retained by the Servicer on such Distribution Date.  Such
amounts shall be compensation for the activities of the Certificate
Administrator and the Trustee hereunder.  The Certificate Administrator and the
Trustee shall be required to pay all expenses incurred by it in connection with
its activities hereunder and shall not be entitled to reimbursement therefor,
except as specifically provided herein.

       Section 3.10. REPORTS TO THE TRUSTEE; CUSTODIAL ACCOUNT FOR P&I 
STATEMENTS.  On or before each Determination Date, the Servicer shall deliver 
or cause to be delivered to the Trustee or its designee a statement in 
electronic or written form as may be agreed upon by the Servicer and the 
Trustee containing the information described in Section 4.2 and such other 
information as may be necessary for the Trustee to compute the amounts to be 
distributed to the Certificateholders by the Trustee (the "Servicer's Section 
3.10 Report").  Not later than 25 days after each Distribution Date, the 
Servicer shall forward or cause to be forwarded to the Trustee a statement, 
certified by a Servicing Officer, setting forth the status of the Custodial 
Account for P&I as of the close of business on the related Distribution Date, 
stating that all distributions from the Custodial Account for P&I required to 
be made by this Agreement have been made for the period covered by such 
statement (or if any required distribution has not been made, specifying the 
nature and status thereof) and showing, for the period covered by such 
statement, the aggregate of deposits into and withdrawals from the Custodial 
Account for P&I for each category of deposit specified in Section 3.2 and 
each category of withdrawal specified in Section 3.3.  Such statement shall 
also include information as to the aggregate Principal Balance of all of the 
Loans as of the last day of the calendar month immediately preceding such 
Distribution Date.  Copies of such statement shall be provided to any 
Certificateholder upon request by the Servicer, or by the Trustee so long as 
the Trustee has received the report as stipulated above at the Servicer's 
expense if the Servicer shall fail to provide such copies.

       Section 3.11. ANNUAL STATEMENT AS TO COMPLIANCE.  The Servicer will 
deliver to the Trustee, on or before December 31 of each year, beginning 
December 31, 1999, an Officer's Certificate stating as to each signer 
thereof, that (i) a review of the activities of the Servicer during the 
preceding calendar year and of performance under this Agreement has been made 
under such officer's supervision, and (ii) to the best of such officer's 
knowledge, based on such review, the Servicer has fulfilled all of its 
obligations under this Agreement throughout such year, or if there has been a 
default in the fulfillment of any such obligation, specifying each such 
default known to such officer and the nature and status thereof.  Copies of 
such statement shall be provided to the Rating Agency and to any 
Certificateholder upon request by the Servicer, or by the Trustee at the 
Servicer's expense if the Servicer shall fail to provide such copies and the 
Trustee is aware that the Servicer has not so provided copies and so long as 
the Trustee shall have received the report as stipulated above.

       Section 3.12. ANNUAL INDEPENDENT PUBLIC ACCOUNTANTS' SERVICING REPORT. 
On or before December 31 of each year, beginning December 31, 1999, the 
Servicer, at its expense, shall cause a firm of independent public 
accountants who are members of the American Institute of Certified Public 
Accountants to furnish a statement to the Trustee and the Rating Agency to 
the effect that such firm has examined certain documents and records relating 
to the servicing of the Loans and that, either (a) on the basis of such 
examination conducted substantially in compliance with the audit program for 
mortgages serviced for FHLMC, such firm is of the opinion that such servicing 
has been conducted in compliance with the manner of servicing set forth in 
agreements substantially similar to this Agreement except for (i) such 
exceptions as such firm shall believe to be immaterial and (ii) such other 
exceptions as shall be set forth in such statement or, (b) that their 
examination conducted substantially in compliance with the uniform single 
audit program for mortgage bankers 



                                     61
<PAGE>

disclosed no exceptions or errors in records relating to mortgage loans 
serviced for others that in their opinion are material and that Paragraph 4 
of that program requires them to report.  Copies of such statement shall be 
provided to Certificateholders upon request by the Servicer, or by the 
Trustee at the Servicer's expense if the Servicer shall fail to provide such 
copies and the Trustee is aware that the Servicer has not so provided copies 
and so long as the Trustee shall have received the report as stipulated above.

       Section 3.13. ACCESS TO CERTAIN DOCUMENTATION AND INFORMATION REGARDING
THE LOANS.  The Servicer shall provide access to the Trustee or to its designees
at its request, and to Certificateholders which are savings and loan
associations, banks or insurance companies, the OTS, the FDIC and the
Supervisory Agents and examiners of the OTS and the FDIC or examiners of any
other federal or state banking or insurance regulatory authority to the
documentation regarding the Loans if so required by applicable regulations of
the OTS or other regulatory authority, such access to be afforded without charge
but only upon reasonable request and during normal business hours at the offices
of the Servicer designated by it.  The Trustee or its designee may without
charge copy any document or electronic record maintained by the Servicer
hereunder.

       Section 3.14. [Reserved].

       Section 3.15. SALE OF DEFAULTED LOANS AND REO PROPERTIES.

              (a)    With respect to any Defaulted Loan or REO Property which
       the Servicer has determined to sell in accordance with the standards set
       forth in Section 3.7, the Servicer shall deliver to the Trustee an
       Officer's Certificate to the effect that no satisfactory arrangements can
       be made for collection of delinquent payments thereon pursuant to Section
       3.2, and, consistent with the servicing standard set forth in Section 3.1
       and with a view to the best economic interest of the Trust Fund, the
       Servicer has determined to sell such Loan or REO Property in accordance
       with this Section 3.15.  The Servicer may then offer to sell to any
       Person any Defaulted Loan or any REO Property or, subject to the
       following sentence, purchase any such Defaulted Loan or REO Property (in
       each case at the Repurchase Price therefor), but shall, in any event, so
       offer to sell any REO Property no later than the time determined by the
       Servicer to be sufficient to result in the sale of such REO Property
       within the period specified in Section 3.7(c).  The Servicer shall accept
       the highest bid received from any Person for any Defaulted Loan or any
       REO Property in an amount at least equal to the Purchase Price therefor
       or, at its option, if it has received no bid at least equal to the
       Purchase Price therefor, purchase the Defaulted Loan or REO Property at
       the Purchase Price.

              In the absence of any such bid or purchase by the Servicer, the
       Servicer shall accept the highest bid received from any Person that is
       determined by the Servicer to be a fair price for such Defaulted Loan or
       REO Property, if the highest bidder is a Person other than an Interested
       Person, or is determined to be such a price by the Trustee, if the
       highest bidder is an Interested Person.  Notwithstanding anything to the
       contrary herein, neither the Trustee, in its individual capacity, nor any
       of its Affiliates may bid for or purchase any Defaulted Loan or any REO
       Property pursuant hereto.




                                     62
<PAGE>

              The Servicer shall not be obligated by either of the foregoing
       paragraphs or otherwise to accept the highest bid if the Servicer
       determines, in accordance with the servicing standard stated in Section
       3.1, that rejection of such bid would be in the best interests of the
       Certificateholders.  In addition, the Servicer may accept a lower bid if
       it determines, in accordance with the servicing standard stated in
       Section 3.1, that acceptance of such bid would be in the best interests
       of the Certificateholders (for example, if the prospective buyer making
       the lower bid is more likely to perform its obligations, or the terms
       offered by the prospective buyer making the lower bid are more
       favorable).  In the event that the Servicer determines with respect to
       any REO Property that the bids being made with respect thereto are not in
       the best interests of the Certificateholders and that the end of the
       period referred to in Section 3.7(c) with respect to such REO Property is
       approaching, the Servicer shall seek an extension of such period in the
       manner described in Section 3.7(c).

              (b)    In determining whether any bid received from an Interested
       Person represents a fair price for any Defaulted Loan or any REO
       Property, the Trustee may conclusively rely on the opinion of an
       Independent appraiser or other expert in real estate matters retained by
       the Trustee the expense of which shall be an expense of the Trust Fund. 
       In determining whether any bid constitutes a fair price for any Defaulted
       Loan or any REO Property, the Servicer or the Trustee (or, if applicable,
       such appraiser) shall take into account, and any appraiser or other
       expert in real estate matters shall be instructed to take into account,
       as applicable, among other factors, the period and amount of any
       delinquency on the affected Defaulted Loan, the physical condition of the
       related Mortgaged Property or such REO Property, the state of the local
       economy and the Trust Fund's obligation to dispose of any REO Property
       within the time period specified in Section 3.7(c).

              (c)    The Servicer shall act on behalf of the Trust Fund in
       negotiating and taking any other action necessary or appropriate in
       connection with the sale of any Defaulted Loan or REO Property, including
       the collection of all amounts payable in connection therewith.  Any sale
       of a Defaulted Loan or any REO Property shall be without recourse to, or
       representation or warranty by, the Trustee, the Depositor, the Servicer
       or the Trust Fund (except that any contract of sale and assignment and
       conveyance documents may contain customary warranties of title, so long
       as the only recourse for breach thereof is to the Trust Fund), and, if
       consummated in accordance with the terms of this Agreement, neither the
       Servicer, the Depositor nor the Trustee shall have any liability to the
       Trust Fund or any Certificateholder with respect to the purchase price
       therefor accepted by the Servicer or the Trustee.

              (d)    The proceeds of any sale after deduction of the expenses of
       such sale incurred in connection therewith shall be promptly deposited in
       the Custodial Account for P&I in accordance with Section 3.2(b).

       Section 3.16. DELEGATION OF DUTIES.  In the ordinary course of business,
the Servicer or the Trustee may at any time delegate any duties hereunder to any
Person who agrees to conduct such duties in accordance with the applicable terms
of this Agreement.  In case of such delegation, the 



                                     63
<PAGE>

Servicer or the Trustee shall supervise, administer, monitor and oversee the 
activities of such Person hereunder to insure that such Person performs such 
duties in accordance herewith and shall be responsible for the acts and 
omissions of such Person to the same extent as it is responsible for its own 
actions or omissions hereunder.  Any such delegations shall not relieve the 
Servicer or the Trustee of its liability and responsibility with respect to 
such duties, and shall not constitute a resignation within the meaning of 
Section 6.4 hereof and shall be revocable by any successor Servicer or the 
Trustee.

       Section 3.17. [RESERVED]. 

       Section 3.18. [RESERVED].

       Section 3.19. APPOINTMENT OF A SPECIAL SERVICER.  The Servicer may enter
into a special servicing agreement with an unaffiliated holder of a 100%
Percentage Interest of a Subordinate  Certificate or a holder of a class of
securities representing interests in such Subordinate Certificate and/or other
subordinate mortgage pass-through certificates, such agreement to be (i)
substantially in the form of Exhibit R hereto or (ii) subject to each Rating
Agency's acknowledgment that the ratings of the Certificates in effect
immediately prior to the entering into of such agreement would not be qualified,
downgraded or withdrawn and the Certificates would not be placed on credit
review status (except for possible upgrading) as a result of such agreement. 
Any such agreement may contain provisions whereby such holder may instruct the
Servicer to commence or delay foreclosure proceedings with respect to delinquent
Loans and will contain provisions for the deposit of cash by the holder that
would be available for distribution to Certificateholders if Liquidation
Proceeds are less than they otherwise may have been had the Servicer acted in
accordance with its normal procedures.

       Section 3.20. ALLOCATION OF REALIZED LOSSES.  Prior to each Distribution
Date, the Servicer shall determine the amount of Realized Losses, if any, with
respect to each Loan.  The amount of Realized Losses shall be evidenced by an
Officer's Certificate signed by a Responsible Officer of the Servicer.  All
Realized Losses, except for Special Hazard Losses, Fraud Losses and Bankruptcy
Losses in excess of the designated amounts of the applicable Special Hazard
Coverage, Fraud Coverage and Bankruptcy Coverage (each, as defined herein), will
be allocated as follows: (i) for losses allocable to principal  (a) first, to
the Class B-5 Certificates, until the Class Principal Balance thereof has been
reduced to zero, (b) second, to the Class B-4 Certificates, until the Class
Principal Balance thereof has been reduced to zero, (c) third, to the Class B-3
Certificates, until the Class Principal Balance thereof has been reduced to
zero, (d) fourth, to the Class B-2 Certificates, until the Class Principal
Balance thereof has been reduced to zero, (e) fifth, to the Class B-1
Certificates, until the Class Principal Balance thereof has been reduced to
zero, (f) sixth, to the Class M Certificates, until the Class Principal Balance
thereof has been reduced to zero, and (g) seventh, to the Senior Certificates 
(other than the Class A-P and the Interest Only Certificates), pro rata,
according to their Class Principal Balances (or, in the case of any of the
Accrual Certificates, the Class Principal Balance of such certificates on the
Closing Date, if lower) in reduction of their respective Class or Principal
Balances, as applicable; PROVIDED, HOWEVER, that if the loss is recognized with
respect to a Discount Loan, the applicable Discount Fraction of such loss will
first 



                                     64
<PAGE>

be allocated to the Class A-P Certificates and the remainder of such loss 
will be allocated as described above in this clause (i) and (ii) for losses 
allocable to interest (a) first, to the Class B-5 Certificates, in reduction 
of accrued but unpaid interest thereon and then in reduction of the Class 
Principal Balance of such Certificates, (b) second, to the Class B-4 
Certificates, in reduction of accrued but unpaid interest thereon and then in 
reduction of the Class Principal Balance of such Certificates, (c) third, to 
the Class B-3 Certificates, in reduction of accrued but unpaid interest 
thereon and then in reduction of the Class Principal Balance of such 
Certificates, (d) fourth, to the Class B-2 Certificates, in reduction of

and then in reduction of the Class Principal Balance of such Certificates, 
and (g) seventh, to the applicable Senior Certificates (other than the Class 
A-P Certificates), pro rata according to accrued but unpaid interest thereon 
and then pro rata according to their Class Principal Balances in reduction of 
their respective Class Principal Balances, as applicable.

       Special Hazard Losses in excess of the Special Hazard Coverage, Fraud
Losses in excess of the Fraud Coverage and Bankruptcy Losses in excess of the
Bankruptcy Coverage shall be allocated among the related Senior Certificates and
the Subordinate Certificates by Pro Rata Allocation.

       On each Distribution Date, after giving effect to the principal
distributions and allocations of losses as provided in this Agreement (without
regard to this paragraph), if the Aggregate Certificate Principal Balance of all
outstanding Classes of Certificates exceeds the aggregate principal balance of
the Loans, after deduction of (i) all principal payments due on or before the
Cut-Off Date in respect of each such Loan whether or not paid and (ii) all
amounts of principal in respect of each such Loan that have been received or
advanced and included in the related Available Distribution Amount, and all
losses in respect of such Loans that have been allocated to the Certificates, on
such Distribution Date or prior Distribution Dates, then such excess will be
deemed a principal loss and will be allocated to the most junior Class of
Subordinate Certificates then outstanding, in reduction of the Certificate
Principal Balance thereof.

       Certificate effected by distributions of principal or allocations of
       Realized Losses with respect to Loans made on any Distribution Date shall
       be binding upon all Holders of such Certificate and of any Certificate

              (d)    Whenever, on the basis of Curtailments, Payoffs and Monthly

       received and expected to be received during the applicable Prepayment

       distributable on the next Distribution Date, the Trustee or the
       Certificate Administrator, if any, shall, no later than the Determination

              such Distribution Date, and

                     (ii)    if such funds are available, (A) such final
              distribution will be payable on such Distribution Date, but only
              upon presentation and surrender of such Certificate at the office

              the applicable Determination Date;

                     (iv)   The amount of Bankruptcy Coverage available to the
              Certificateholders remaining as of the close of business on the

                     (ix)   The total amount of Payoffs and Curtailments
              received during the related Prepayment Period.

       Upon request by any Certificateholder, the Trustee or the Certificate
Administrator (if so appointed by the Trustee), as soon as reasonably
practicable, shall provide the requesting Certificateholder with such
information as is necessary and appropriate, in Trustee's or the Certificate
Administrator's sole discretion, for purposes of satisfying applicable reporting
requirements under Rule 144A of the Securities Act.

       (b)    Upon request to the Trustee or Certificate Administrator (if so
appointed by the Trustee) by any Certificateholder who is a Holder thereof at
the time of making such request (an "Eligible Certificateholder"), the Trustee
or the Certificate Administrator, if applicable, shall provide in electronic
format loan by loan data with respect to the payment experience of the Loans
containing at least the fields of information listed on Exhibit E hereto (based
on information provided by the Servicer).  In addition, upon the written request
of any Eligible Certificateholder, the Trustee or the Certificate Administrator
shall provide similar loan by loan data with respect to any prior monthly
remittance report to the Certificateholders pursuant to this Agreement (as and
when such information becomes available).  The expense of providing any tape or
disk pursuant to this subsection shall be an expense of the Eligible
Certificateholder.  The Trustee or the Certificate Administrator shall include
in each monthly remittance report delivered pursuant to Section 4.2(a) a
statement that the monthly loan by loan information described in this subsection
is available upon request and at the expense of any Eligible Certificateholder
directed to the Trustee or the Certificate Administrator.

       Section 4.3.  ADVANCES BY THE SERVICER; DISTRIBUTION REPORTS TO THE
TRUSTEE.  To the extent described below, the Servicer is obligated to advance
its own funds to the Certificate Account to cover any shortfall between (i)
payments scheduled to be received in respect of Loans serviced by such Servicer,
and (ii) the amounts actually deposited in the Certificate Account on account of
such payments.  The Servicer's obligation to make any Advance or Advances
described in this Section 4.3 is effective only to the extent that such Advance
is, in the good faith judgment of the Servicer, reimbursable from Insurance
Proceeds or Liquidation Proceeds of the related Loans or recoverable as late
Monthly Payments with respect to the related Loans or otherwise.

       Prior to the close of business on each Determination Date, the Servicer
shall determine whether or not it will make an Advance on the next Withdrawal
Date and shall furnish a statement to the Certificate Administrator, if any, the
Trustee, the Paying Agent, if any, and to any Certificateholder requesting the
same, setting forth the aggregate amount to be distributed on the next
succeeding Distribution Date on account of principal and interest in respect of
the Loans, stated separately.  In the event that full scheduled amounts of
principal and interest in respect of the related Loans shall not have been
received by or on behalf of the Servicer prior to the Withdrawal Date preceding
such Distribution Date and the Servicer shall have determined that an Advance
shall be 



                                     68
<PAGE>

made in accordance with this Section 4.3, the Servicer shall so 
specify and shall specify the aggregate amount of such Advance.

       In the event that the Servicer shall be required to make an Advance, it
shall on the Withdrawal Date either (i) deposit in the Certificate Account an
amount equal to such Advance, (ii) direct the Trustee or the Certificate
Administrator (if so appointed by the Trustee) to make an appropriate entry in
the records of the Certificate Account that funds in such account being held for
future distribution or withdrawal have been, as permitted by this Section 4.3,
used by such Servicer to make such Advance, or (iii) make advances in the form
of any combination of (i) and (ii) aggregating the amount of such Advance.  Any
funds being held for future distribution to Certificateholders and so used shall
be replaced by the related Servicer by deposit in the Certificate Account on any
future Withdrawal Date to the extent that funds in the Certificate Account on
the related Distribution Date with respect to the related Loans shall be less
than payments to Certificateholders required to be made on such date with
respect to such Loans.  The Servicer is entitled to receive from the Custodial
Accounts for P&I established by the Servicer under its supervision amounts
received by the Servicer on particular Loans as late payments of principal and
interest or as Liquidation or Insurance Proceeds and respecting which the
Servicer has made an unreimbursed Advance of principal and interest.  The
Servicer is also entitled to receive other amounts from the related Custodial
Accounts for P&I established by the Servicer under its supervision to reimburse
the Servicer for prior Nonrecoverable Advances.

       In accordance with Section 3.3, Advances are reimbursable to the Servicer
from cash in the Custodial Account for P&I to the extent that the Servicer shall
determine that any such advances previously made are Nonrecoverable Advances
pursuant to Section 4.4.

       In the event that the Trustee has appointed a Certificate Administrator,
prior to 5:00 P.M. New York City time on the Withdrawal Date, the Certificate
Administrator shall provide the Trustee with a statement regarding the amount of
principal and interest, the Residual Distribution Amount and the Excess
Liquidation Proceeds to be distributed to each Class of Certificates on such
Distribution Date (such amounts to be determined in accordance with the
definition of "Certificate Distribution Amount", Section 4.1 hereof and other
related definitions set forth in Article I hereof).

       Section 4.4.  NONRECOVERABLE ADVANCES.  Any Advance previously made by
the Servicer with respect to a Loan that the Servicer shall determine in its
good faith judgment not to be ultimately recoverable from Insurance Proceeds or
Liquidation Proceeds or otherwise with respect to such Loan or recoverable as
late Monthly Payments with respect to such Loan shall be a Nonrecoverable
Advance.  The determination by the Servicer that it has made a Nonrecoverable
Advance or that any advance would constitute a Nonrecoverable Advance, shall be
evidenced by an Officer's Certificate of the Servicer delivered to the Trustee
on the Determination Date and detailing the reasons for such determination. 
Notwithstanding any other provision of this Agreement, any insurance policy
relating to the Loans, or any other agreement relating to the Loans to which the
Depositor or the Servicer is a party, (a) the Depositor and the Servicer shall
not be obligated to, and shall not, make any advance that, after reasonable
inquiry and in its sole discretion, the Depositor or the Servicer shall
determine would be a Nonrecoverable Advance, and (b) the 



                                     69
<PAGE>

Depositor and the Servicer shall be entitled to reimbursement for any 
Advance as provided in Section 3.5 of this Agreement.

       Section 4.5.  FORECLOSURE REPORTS.  Each year beginning in 1999 the
Servicer shall make any reports of foreclosures and abandonments of any
Mortgaged Property required by Section 6050J of the Code.  In order to
facilitate this reporting process, the Servicer, on or before February 28th of
each year, commencing with 1999, shall provide to the Internal Revenue Service,
the Trustee and the Certificate Administrator, if any, reports relating to each
instance occurring during the previous calendar year in which the Servicer
(i) on behalf of the Trustee acquires an interest in a Mortgaged Property
through foreclosure or other comparable conversion in full or partial
satisfaction of a Loan, or (ii) knows or has reason to know that a Mortgaged
Property has been abandoned.  The reports from the Servicer shall be in form and
substance sufficient to meet the reporting requirements imposed by such Section
6050J.

       Section 4.6.  ADJUSTMENT OF SERVICING FEES WITH RESPECT TO PAYOFFS.  The
aggregate amount of the Servicing Fee subject to retention from deposit into or
withdrawal from the Certificate Account by the Servicer, in any month of
distribution shall be decreased by any Compensating Interest due and owing with
respect to any Loan with respect to which a Payoff has occurred in the related
Prepayment Period.  The Servicer shall include the amount of any such
Compensating Interest with the deposits into the Certificate Account on the
related Withdrawal Date.  Notwithstanding the foregoing, the amount by which the
Servicing Fee may be reduced with respect to the related Prepayment Period
pursuant to this Section 4.6 shall not exceed an amount greater than the amount
described in clause (i) of the definition of Compensating Interest for all Loans
as to which Payoffs have occurred and the rights of the Certificateholders to
such portion of the Servicing Fee shall not be cumulative. 

       Section 4.7.  PROHIBITED TRANSACTIONS TAXES AND OTHER TAXES.

              (a)    In the event that any tax (including a tax on "prohibited
       transactions" as defined in Section 860F(a)(2) of the Code and including
       any and all interest, penalties, fines and additions to tax, as well as
       any and all reasonable counsel fees and out-of-pocket expenses incurred
       in contesting the imposition of such tax) is imposed on the Trust Fund
       and is not otherwise paid pursuant to Section 4.7(b) hereof, the Servicer
       shall pay such taxes when and as the same shall be due and payable (but
       such obligation shall not prevent the Servicer, the Trustee, the
       Certificate Administrator, if any, or any other appropriate Person from
       contesting any such tax in appropriate proceedings and shall not prevent
       the Servicer from withholding payment of such tax, if permitted by law,
       pending the outcome of such proceedings); PROVIDED, that the Servicer
       shall be entitled to be indemnified for any such taxes (excluding taxes
       referred to in Section 4.7(b)) to the extent set forth in Section 6.3
       hereof so long as the Servicer's failure to exercise reasonable care with
       respect to the performance of its duties hereunder was not the primary
       cause of the imposition of such taxes.  If the Servicer is indemnified
       for such taxes pursuant to this Section 4.7(a), such amount shall be
       first charged against amounts otherwise distributable to the Holders of
       Component R-1 of the Class R Certificate (or, if the tax relates to REMIC
       II, Component R-2 





                                     70

<PAGE>

       of the Class R Certificate) on a pro rata basis, then against amounts 
       otherwise distributable with respect to the REMIC I Regular Interests 
       (or, if the tax relates to REMIC II, to the Holders of the REMIC II 
       Certificates) on a pro rata basis.  The Trustee is hereby authorized 
       to retain from amounts otherwise distributable to the 
       Certificateholders sufficient funds to reimburse the Servicer for the 
       payment of such tax for which the Servicer is entitled to 
       indemnification.

              (b)    The Servicer shall pay on written demand, and shall
       indemnify and hold harmless the Trust Fund from and against, any and all
       taxes imposed on the Trust Fund (including, for this purpose, any and all
       interest, penalties, fines and additions to tax, as well as any and all
       reasonable counsel fees and out-of-pocket expenses incurred in contesting
       the imposition of such tax).

       Section 4.8.  TAX ADMINISTRATION.

              (a)    The Trustee is hereby appointed as attorney-in-fact and
       agent for the initial Tax Matters Person; PROVIDED, that the Trustee may
       appoint, and hereby does so appoint, the Certificate Administrator as
       attorney-in-fact and agent for the Tax Matters Person.  The Trustee may,
       by written notice delivered to the Certificate Administrator, revoke the
       appointment of the Certificate Administrator as attorney-in-fact and
       agent for the Tax Matters Person, in which case the Trustee shall act in
       such capacity.

              (b)    In order to enable the Trustee or the Certificate
       Administrator, as applicable, to perform its duties as set forth in this
       Section 4.8 and Section 3.1(b), the Servicer agrees to provide any tax
       forms, instruments or other documents related thereto, as the Trustee or
       the Certificate Administrator, as applicable, may reasonably request,
       including, without limitation, any tax forms, instruments or other
       documents prepared by the Servicer pursuant to this Section 4.8  In order
       to enable the Trustee or the Certificate Administrator, as applicable, to
       perform its duties as set forth in this Section 4.8 and Section 3.1(b),
       the Servicer shall use its best efforts to cause to be delivered to the
       Trustee or the Certificate Administrator, as applicable, within ten (10)
       days after the Closing Date all information or data that the Trustee or
       the Certificate Administrator, as applicable, determines to be relevant
       for tax purposes to the valuations and offering prices of the
       Certificates, including, without limitation, the price, yield, prepayment
       assumption and projected cash flows. Thereafter, the Servicer shall use
       its best efforts to provide to the Trustee or the Certificate
       Administrator, as applicable,  promptly upon request therefor, any such
       additional information or data that the Trustee or the Certificate
       Administrator, as applicable, may, from time to time, request in order to
       enable the Trustee or the Certificate Administrator, as applicable, to
       perform its duties as set forth in this Section 4.8 and Section 3.1(b).

       Section 4.9.  EQUAL STATUS OF SERVICING FEE.  The right of the Servicer
to receive its Servicing Fee will be equal and not subordinate to the right of
the Certificateholders to receive principal and interest payments based on their
interests as provided herein.  The Servicer's Servicing Fee may be collected
from Monthly Payments as received pursuant to Section 3.2 without deposit 



                                     71
<PAGE>

into the Certificate Account, whereas the Certificateholders' 
distributions shall be made on a delayed basis as set forth in the 
terms of the Certificates.

       Section 4.10. APPOINTMENT OF PAYING AGENT AND CERTIFICATE ADMINISTRATOR. 
The Trustee may appoint an Eligible Institution to act as a paying agent (the
"Paying Agent") or a certificate administrator (the "Certificate
Administrator"), as the case may be, in order to delegate to such Eligible
Institution any of its duties under this Agreement to administer the issuance,
transfer and exchange of the Certificates, administer payments to
Certificateholders or prepare information related to the Certificates; PROVIDED,
that the Trustee shall remain primarily responsible for any duties so delegated;
PROVIDED, FURTHER, that the Trustee shall receive no additional compensation in
connection with such appointment and delegation.  

       Initially, LaSalle National Bank will be the Certificate Administrator
and Paying Agent.  If LaSalle National Bank ceases to serve as Certificate
Administrator or Paying Agent, the Trustee shall send written notice to all
Certificateholders (i) indicating that LaSalle National Bank is no longer in
such capacity and (ii) setting forth its replacement, if any, appointed pursuant
to this Section 4.10.

       in the form provided for herein executed by the Trustee or any
       Authenticating Agent by manual signature, and such certificate upon any

                     (i)    Each Person who has or who acquires any Ownership

              Person acquiring any Ownership Interest in a Residual Certificate
              are expressly subject to the following provisions:

                            (A)    Each Person holding or acquiring any
                     Ownership Interest in a Residual Certificate shall be a
                     Permitted Transferee and shall promptly notify the Trustee
                     or the Certificate Registrar if not the same Person as the
                     Trustee of any change or impending change in its status as
                     a Permitted Transferee.

                            (B)    In connection with any proposed Transfer of
                     any Ownership Interest in a Residual Certificate to a U.S.
                     Person, the Trustee or the Certificate Registrar if not the
                     same Person as the Trustee shall require delivery to it,
                     and shall not register the Transfer of any Residual
                     Certificate until its receipt of (1) an affidavit and
                     agreement (a "Transferee Affidavit and Agreement") attached
                     hereto as Exhibit J from the proposed Transferee, in form
                     and substance satisfactory to the Depositor, representing
                     and warranting, among other things, that it is not a
                     Non-U.S. Person, that such transferee is a Permitted
                     Transferee, that it is not acquiring its Ownership Interest
                     in the Residual Certificate that is the subject of the
                     proposed Transfer as a nominee, trustee or agent for any
                     Person who is not a Permitted

                     Transferee, that for so long as it retains its Ownership 
                     Interest in a Residual Certificate, it will endeavor to 
                     remain a Permitted Transferee, and that it has reviewed 
                     the provisions of this Section 5.1(c) and agrees to be 
                     bound by them, and (2) a certificate, attached hereto as 
                     Exhibit I, from the Holder wishing to transfer the 
                     Residual Certificate, in form and substance satisfactory 
                     to the Depositor, representing and warranting, among 
                     other things, that no purpose of the proposed Transfer 
                     is to allow such Holder to impede the assessment or 
                     collection of tax.

                            (C)    Notwithstanding the delivery of a Transferee
                     Affidavit and Agreement by a proposed Transferee under
                     clause (B) above, if the Trustee or the Certificate
                     Registrar if not the same Person as the Trustee has actual
                     knowledge that the proposed Transferee is not a Permitted
                     Transferee, no Transfer of an Ownership Interest in a
                     Residual Certificate to such proposed Transferee shall be
                     effected.

                            (D)    Each Person holding or acquiring any
                     Ownership Interest in a Residual Certificate agrees by
                     holding or acquiring such Ownership Interest (i) to require
                     a Transferee Affidavit and Agreement from any other Person
                     to whom such Person attempts to transfer its Ownership
                     Interest and to provide a certificate to the Trustee or the
                     Certificate Registrar if not the same Person as the Trustee
                     in the form attached hereto as Exhibit J; (ii) to obtain
                     the express written consent of the Depositor prior to any
                     transfer of such Ownership Interest, which consent may be
                     withheld in the Depositor's sole discretion; and (iii) to
                     provide a certificate to the Trustee or the Certificate
                     Registrar if not the same Person as the Trustee in the form
                     attached hereto as Exhibit I.

                     (ii)   The Trustee or the Certificate Registrar if not the
              same Person as the Trustee shall register the Transfer of any
              Residual Certificate only if it shall have received the Transferee
              Affidavit and Agreement, a certificate of the Holder requesting
              such transfer in the form attached hereto as Exhibit J and all of
              such other documents as shall have been reasonably required by the
              Trustee or the Certificate Registrar if not the same Person as the
              Trustee as a condition to such registration.

                     (iii)  (A) If any "disqualified organization" (as defined
              in Section 860E(e)(5) of the Code) shall become a Holder of a
              Residual Certificate, then the last preceding Permitted Transferee
              shall be restored, to the extent permitted by law, to all rights
              and obligations as Holder thereof retroactive to the date of
              registration of such Transfer of such Residual Certificate.  If
              any Non-U.S. Person shall become a Holder of a Residual
              Certificate, then the last preceding Holder which is a U.S. Person
              shall be restored, to the extent permitted by law, to all rights
              and obligations as Holder thereof retroactive to the date of
              registration of the Transfer to such Non-U.S. Person of such
              Residual Certificate.  If a transfer of a Residual Certificate is

              disregarded pursuant to the provisions of Treasury Regulations
              Section 1.860E-1 or Section 1.860G-3, then the last preceding
              Permitted Transferee shall be restored, to the extent permitted by
              law, to all rights and obligations as Holder thereof retroactive
              to the date of registration of such Transfer of such Residual
              Certificate.  The Trustee, the Certificate Administrator, the
              Certificate Registrar and the Paying Agent shall be under no
              liability to any Person for any registration of Transfer of a
              Residual Certificate that is in fact not permitted by this Section
              5.1(c) or for making any payments due on such Certificate to the
              Holder thereof or for taking any other action with respect to such
              Holder under the provisions of this Agreement.

                            (B)    If any purported Transferee shall become a
                     Holder of the Residual Certificate in violation of the
                     restrictions in this Section 5.1(c) and to the extent that
                     the retroactive restoration of the rights of the Holder of
                     such Residual Certificate as described in clause (iii)(A)
                     above shall be invalid, illegal or unenforceable, then the
                     Depositor shall have the right, without notice to the
                     Holder or any prior Holder of such Residual Certificate, to
                     sell such Residual Certificate to a purchaser selected by
                     the Depositor on such terms as the Depositor may choose. 
                     Such purported Transferee shall promptly endorse and
                     deliver the Residual Certificate in accordance with the
                     instructions of the Depositor.  Such purchaser may be the
                     Depositor itself or any affiliate of the Depositor.  The
                     proceeds of such sale, net of the commissions (which may
                     include commissions payable to the Depositor or its
                     affiliates), expenses and taxes due, if any, shall be
                     remitted by the Depositor to such purported Transferee. 
                     The terms and conditions of any sale under this clause
                     (iii)(B) shall be determined in the sole discretion of the
                     Depositor, and the Depositor shall not be liable to any
                     Person having an Ownership Interest in the Residual
                     Certificate as a result of its exercise of such discretion.

                     (iv)   The Depositor, on behalf of the Trustee, shall make
              available, upon written request from the Trustee, or the
              Certificate Administrator all information necessary to compute any
              tax imposed (A) as a result of the Transfer of an Ownership
              Interest in the Residual Certificate to any Person who is not a
              Permitted Transferee, including the information regarding "excess
              inclusions" of such Residual Certificate required to be provided
              to the Internal Revenue Service and certain Persons as described
              in Treasury Regulation Section 1.860D-1(b)(5), and (B) as a result
              of any regulated investment company, real estate investment trust,
              common trust fund, partnership, trust, estate or organizations
              described in Section 1381 of the Code having as among its record
              holders at any time any Person who is not a Permitted Transferee. 
              Reasonable compensation for providing such information may be
              required by the Depositor from such Person.

                     (v)    The provisions of this Section 5.1 set forth prior
              to this Section 5.1(c)(v) may be modified, added to or eliminated,
              PROVIDED, that there shall have been delivered to the Trustee and
              the Certificate Administrator the following:

                            (A)    written notification from each Rating Agency
                     to the effect that the modification, addition to or
                     elimination of such provisions will not cause such Rating
                     Agency to downgrade its then-current Ratings of the
                     Certificates; and

                            (B)    an Opinion of Counsel, in form and substance
                     satisfactory to the Depositor (as evidenced by a

                     modification, addition to or absence of such provisions
                     will not cause the Trust Fund to cease to qualify as a
                     REMIC and will not create a risk that (1) the Trust Fund
                     may be subject to an entity-level tax caused by the
                     Transfer of any Residual Certificate to a Person which is
                     not a Permitted Transferee or (2) a Certificateholder or
                     another Person will be subject to a REMIC-related tax
                     caused by the Transfer of a Residual Certificate to a
                     Person which is not a Permitted Transferee.

                     (vi)   The following legend shall appear on all Residual

                            ORGANIZATION OR AN AGENT OF A DISQUALIFIED
                            ORGANIZATION, SUCH REGISTRATION SHALL BE DEEMED TO
                            BE OF NO LEGAL FORCE OR EFFECT WHATSOEVER AND SUCH
                            PERSON SHALL NOT BE DEEMED TO BE A CERTIFICATEHOLDER
                            FOR ANY PURPOSE HEREUNDER, INCLUDING, BUT NOT
                            LIMITED TO, THE RECEIPT OF DISTRIBUTIONS ON THIS
                            CERTIFICATE.  EACH HOLDER OF THE CLASS R CERTIFICATE
                            BY ACCEPTANCE OF THIS CERTIFICATE SHALL BE DEEMED TO
                            HAVE CONSENTED TO THE PROVISIONS OF THIS PARAGRAPH.

                     (vii)  The Holder of the Class R Certificate issued
              hereunder, while not a Disqualified Organization, is the Tax
              Matters Person.

              (d)    In the case of any Subordinate or Class R Certificate
       presented for registration in the name of an employee benefit plan or
       other plan or arrangement subject to the prohibited transaction
       provisions of ERISA or Section 4975 of the Code (or comparable provisions
       of any subsequent enactments) (a "Plan"), a trustee of any Plan, or any
       other Person who is using the "plan assets" of any Plan to effect such
       acquisition, the Trustee or the Certificate Registrar, if not the same
       Person as the Trustee, shall require such transferee to provide an
       Officer's Certificate signed by a Responsible Officer of such transferee
       stating that the transferee is an insurance company using assets of a

       not be an expense of the Trustee, the Certificate Administrator, if any,
       the Certificate Registrar or the Depositor.

              So long as the Class M, Class B-1 and Class B-2 Certificates are

       or Class B Certificates shall be deemed by the acceptance or acquisition
       of such Certificate to have represented that (a) such Person is not a
       Plan, and such Person is not using "plan assets" of any such Plan to
       effect such acquisition or (b) if the transferee is an insurance company
       and the source of funds used to purchase such Certificate is an
       "insurance company general account" (as such term is defined in PTCE
       95-60) and the conditions set forth in Sections I and III of PTCE 95-60
       have been satisfied.

              (e)    No transfer, sale, pledge or other disposition of a Junior
       Subordinate Certificate shall be made unless such transfer, sale, pledge
       or other disposition is made in accordance with this Section 5.1(e) or
       Section 5.1(f). Each Person who, at any time, acquires 



                                     77

       any ownership interest in any Junior Subordinate Certificate shall be 
       deemed by the acceptance or acquisition of such ownership interest to 
       have agreed to be bound by the following provisions of this Section 
       5.1(e) and Section 5.1(f), as applicable.  No transfer of a Junior 
       Subordinate Certificate shall be deemed to be made in accordance with 
       this Section 5.1(e) unless such transfer is made pursuant to an 
       effective registration statement under the Securities Act or unless the 
       Trustee or the Certificate Registrar, if not the same Person as the 
       Trustee, is provided with the certificates and an Opinion of Counsel, 
       if required, on which the Trustee and the Certificate Registrar may 
       conclusively rely, which establishes or establish to the Trustee's or 
       the Certificate Registrar's, as applicable, satisfaction that such 
       transfer is exempt from the registration requirements under the 
       Securities Act, as follows:  In the event that a transfer is to be made 
       in reliance upon an exemption from the Securities Act, the Trustee or 
       the Certificate Registrar, if not the same Person as the Trustee, shall 
       require, in order to assure compliance with the Securities Act, that 
       the Certificateholder desiring to effect such transfer certify to the 
       Trustee and the Certificate Registrar in writing, in substantially the 
       form attached hereto as Exhibit F, the facts surrounding the transfer, 
       with such modifications to such Exhibit F as may be appropriate to 
       reflect the actual facts of the proposed transfer, and that the 
       Certificateholder's proposed transferee certify to the Trustee and the 
       Certificate Registrar in writing, in substantially the form attached 
       hereto as Exhibit G, the facts surrounding the transfer, with such 
       modifications to such Exhibit G as may be appropriate to reflect the 
       actual facts of the proposed transfer.  If such certificate of the 
       proposed transferee does not contain substantially the substance of 
       Exhibit G, the Trustee or the Certificate Registrar, if not the same 
       Person as the Trustee, shall require an Opinion of Counsel satisfactory 
       to it that such transfer may be made without registration, which 
       Opinion of Counsel shall not be obtained at the expense of the Trustee, 
       the Certificate Administrator, the Certificate Registrar, the Trust 
       Fund or the Depositor.  Such Opinion of Counsel shall allow for the 
       forwarding, and the Trustee shall forward, a copy thereof to the Rating 
       Agency. Notwithstanding the foregoing, any Class of Junior Subordinate 
       Certificate may be transferred, sold, pledged or otherwise disposed of 
       in accordance with the requirements set forth in Section 5.1(f).

              (f)    Transfers of the Junior Subordinate Certificates may be
       made in accordance with this Section 5.1(f).  To effectuate a Certificate
       transfer in accordance with this Section 5.1(f), the proposed transferee
       of such Certificate must provide the Trustee, the Certificate Registrar
       and the Depositor with an investment letter substantially in the form of
       Exhibit L attached hereto, which investment letter shall not be an
       expense of the Trustee, the Certificate Administrator, the Certificate
       Registrar or the Depositor, and which investment letter states that,
       among other things, such transferee (i) is a "qualified institutional
       buyer" as defined under Rule 144A, acting for its own account or the
       accounts of other "qualified institutional buyers" as defined under Rule
       144A, and (ii) is aware that the proposed transferor intends to rely on
       the exemption from registration requirements under the Securities Act
       provided by Rule 144A.  Notwithstanding the foregoing, the proposed
       transferee of such Certificate shall not be required to provide the
       Trustee, the Certificate Registrar or the Depositor with Annex 1 or Annex
       2 to the form of Exhibit L attached hereto if the Depositor so consents
       prior to each such transfer.  Such transfers shall be deemed to 



                                     78
<PAGE>

       have complied with the requirements of this Section 5.1(f).  The Holder 
       of a Certificate desiring to effect such transfer does hereby agree to 
       indemnify the Trustee, the Certificate Administrator, if any, the 
       Depositor, and the Certificate Registrar against any liability that may 
       result if transfer is not made in accordance with this Agreement.
       
              (g)    None of the Trustee, the Certificate Administrator, the
       Certificate Registrar or the Paying Agent shall have any liability to the
       Trust Fund arising from a registration or transfer of a Certificate in
       reliance upon a certification, Officer's Certificate, affidavit, ruling
       or Opinion of Counsel described in this Section 5.1.

       Section 5.2.  CERTIFICATES ISSUABLE IN CLASSES; DISTRIBUTIONS OF
PRINCIPAL AND INTEREST; AUTHORIZED DENOMINATIONS.  The aggregate principal
amount of Certificates that may be authenticated and delivered under this
Agreement is limited to the aggregate Principal Balance of the Loans as of the
Cut-Off Date, as specified in the Preliminary Statement to this Agreement,
except for Certificates authenticated and delivered upon registration of
transfer of, or in exchange for, or in lieu of, other Certificates pursuant to
Section 5.3. Such aggregate principal amount shall be allocated among one or
more Classes having designations, types of interests, initial per annum
Remittance Rates, initial Class Principal Balances and last scheduled
Distribution Dates as specified in the Preliminary Statement to this Agreement. 
The aggregate Percentage Interest of each Class of Certificates of which the
Class Principal Balance equals zero as of the Cut-Off Date that may be
authenticated and delivered under this Agreement is limited to 100%. 
Certificates shall be issued in Authorized Denominations.

       Section 5.3.  REGISTRATION OF TRANSFER AND EXCHANGE OF CERTIFICATES.  The
Trustee shall cause to be maintained at one of its offices or at its designated
Certificate Registrar, a Certificate Register in which there shall be recorded
the name and address of each Certificateholder.  Subject to such reasonable
rules and regulations as the Trustee may prescribe, the Certificate Register
shall be amended from time to time by the Trustee or its agent to reflect notice
of any changes received by the Trustee or its agent pursuant to Section 10.5. 
The Trustee hereby appoints itself as the initial Certificate Registrar.  The
Trustee may appoint an Eligible Institution to act as its agent in order to
delegate to such Eligible Institution its duties as Certificate Registrar under
this Agreement

       Upon surrender for registration of transfer of any Certificate to the
Trustee at the office of First Trust of New York, National Association, 100 Wall
Street, Suite 1600, New York, NY 10005, Attention:  Glenn Anderson, or such
other address or agency as may hereafter be provided to the Certificate
Administrator, if any, and the Servicer in writing by the Trustee, the Trustee
shall execute, and the Trustee or any Authenticating Agent shall authenticate
and deliver, in the name of the designated transferee or transferees, one or
more new Certificates of Authorized Denominations of like Percentage Interest. 
At the option of the Certificateholders, Certificates may be exchanged for other
Certificates in Authorized Denominations of like Percentage Interest, upon
surrender of the Certificates to be exchanged at any such office or agency. 
Whenever any Certificates are so surrendered for exchange, the Trustee shall
execute, and the Trustee, or any Authenticating Agent, shall authenticate and
deliver, the Certificates which the Certificateholder making the exchange is
entitled to receive.  Every Certificate presented or surrendered for transfer
shall (if so required by 



                                     79
<PAGE>

the Trustee or any Authenticating Agent) be duly endorsed by, or be accompanied 
by a written instrument of transfer in form satisfactory to the Trustee or any 
Authenticating Agent and duly executed by, the Holder thereof or such Holder's 
attorney duly authorized in writing.

       A reasonable service charge may be made for any such exchange or transfer
of Certificates, and the Trustee or an Authenticating Agent may require payment
of a sum sufficient to cover any tax or governmental charge that may be imposed
in connection with any exchange or transfer of Certificates.

       Upon the transfer of a Class Certificate each transferee that purchases a
Class A Certificate with the assets of one or more Plans shall be deemed to
represent that each such Plan qualifies as an "accredited investor" as defined
in Rule 501(a)(1) of Regulation D under the Securities act.  If at any time the
Class A Certificates fail to receive a rating from any of S&P or Fitch that is
one of the three highest generic rating categories for that respective rating
agency, then such Class A Certificate shall not thereafter be eligible for
transfer to a Plan, and each transferee shall be deemed to represent that it is
not purchasing or holding its Class A Certificate with plan assets of a Plan.

       All Certificates surrendered for exchange or transfer shall be cancelled
by the Trustee or any Authenticating Agent.

       Section 5.4.  MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.  If (i)
any mutilated Certificate is surrendered to the Trustee or any Authenticating
Agent, or (ii) the Trustee or any Authenticating Agent receives evidence to
their satisfaction of the destruction, loss or theft of any Certificate, and
there is delivered to the Trustee or any Authenticating Agent such security or
indemnity as may be required by them to save each of them harmless, then, in the
absence of notice to the Trustee or any Authenticating Agent that such
Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute and the Trustee or any Authenticating Agent shall authenticate and
deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Certificate, a new Certificate of like Percentage Interest.  Upon the
issuance of any new Certificate under this Section 5.4, the Trustee or any
Authenticating Agent may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee or any
Authenticating Agent) connected therewith.  Any replacement Certificate issued
pursuant to this Section 5.4 shall constitute complete and indefeasible evidence
of ownership in the Trust Fund, as if originally issued, whether or not the lost
or stolen Certificate shall be found at any time.

       Section 5.5.  PERSONS DEEMED OWNERS.  The Depositor, the Certificate
Administrator, the Servicer, the Trustee and any agent of any of them may treat
the Person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions pursuant to Section 4.1
and for all other purposes whatsoever, and neither the Depositor, the
Certificate Administrator, if any, the Servicer, the Trustee, the Certificate
Registrar nor any agent of the Depositor, the Certificate Administrator, if any,
the Servicer or the Trustee shall be affected by notice to the contrary.

       Section 5.6.  TEMPORARY CERTIFICATES.  Upon the initial issuance of the
Certificates, the Trustee may execute, and the Trustee or any Authenticating
Agent shall authenticate and deliver, temporary Certificates which are printed,
lithographed, typewritten or otherwise produced, in any Authorized Denomination,
of the tenor of the definitive Certificates in lieu of which they are issued and
with such variations in form from the forms of the Certificates set forth as
Exhibits A and B hereto as the Trustee's officers executing such Certificates
may determine, as evidenced by their execution of the Certificates. 
Notwithstanding the foregoing, the Certificates may remain in the form set forth
in this Section.

       If temporary Certificates are issued, the Trustee shall cause definitive
Certificates to be prepared within ten Business Days of the Closing Date or as
soon as practicable thereafter.  After preparation of definitive Certificates,
the temporary Certificates shall be exchangeable for definitive Certificates
upon surrender of the temporary Certificates at the office or agency of the
Trustee to be maintained as provided in Section 5.10 hereof, without charge to
the Holder.  Any tax or governmental charge that may be imposed in connection
with any such exchange shall be borne by the Depositor.  Upon surrender for
cancellation of any one or more temporary Certificates, the Trustee shall
execute and the Trustee or any Authenticating Agent shall authenticate and
deliver in exchange therefor a like principal amount of definitive Certificates
of Authorized Denominations.  Until so exchanged, the temporary Certificates
shall in all respects be entitled to the same benefits under this Agreement as
definitive Certificates.

       Section 5.7.  BOOK-ENTRY FOR BOOK-ENTRY CERTIFICATES.  Notwithstanding
the foregoing, the Book-Entry Certificates, upon original issuance, shall be
issued in the form of one or more typewritten Certificates of Authorized
Denomination representing the Book-Entry Certificates, to be delivered to DTC,
the initial Clearing Agency, by, or on behalf of, the Depositor.  The Book-Entry
Certificates shall initially be registered on the Certificate Register in the
name of Cede & Co., the nominee of DTC, as the initial Clearing Agency, and no
Beneficial Holder shall receive a definitive certificate representing such
Beneficial Holder's interest in any Class of Book-Entry Certificate, except as
provided above and in Section 5.9. Each Book-Entry Certificate shall bear the
following legend:

       Unless this Certificate is presented by an authorized
       representative of The Depository Trust Company, a New York
       corporation ("DTC"), to the Trustee or its agent for registration
       of transfer, exchange, or payment, and any Certificate issued is
       registered in the name of Cede & Co. or such other name as is
       requested by an authorized representative of DTC (and any payment
       is made to Cede & Co. or to such other entity as is requested by
       an authorized representative of DTC), ANY TRANSFER, PLEDGE OR
       OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
       WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has
       an interest herein.

Unless and until definitive, fully registered Book-Entry Certificates (the
"Definitive Certificates") have been issued to the Beneficial Holders pursuant
to Section 5.9:



                                     81
<PAGE>

              (a)    the provisions of this Section 5.7 shall be in full force
       and effect with respect to the Book-Entry Certificates;

              (b)    the Certificate Administrator, if any, and the Trustee may
       deal with the Clearing Agency for all purposes with respect to the
       Book-Entry Certificates (including the making of distributions on the
       Book-Entry Certificates) as the sole Certificateholder;

              (c)    to the extent that the provisions of this Section 5.7
       conflict with any other provisions of this Agreement, the provisions of
       this Section 5.7 shall control; and

              (d)    the rights of the Beneficial Holders shall be exercised
       only through the Clearing Agency and the DTC Participants and shall be
       limited to those established by law and agreements between such
       Beneficial Holders and the Clearing Agency and/or the DTC Participants. 
       Pursuant to the Depositary Agreement, unless and until Definitive
       Certificates are issued pursuant to Section 5.9, the initial Clearing
       Agency will make book-entry transfers among the DTC Participants and
       receive and transmit distributions of principal and interest on the
       related Class of Book-Entry Certificates to such DTC Participants.

       For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Holders of Book-Entry
Certificates evidencing a specified Percentage Interest, such direction or
consent may be given by the Clearing Agency at the direction of Beneficial
Holders owning Book-Entry Certificates evidencing the requisite Percentage
Interest represented by the Book-Entry Certificates.  The Clearing Agency may
take conflicting actions with respect to the Book-Entry Certificates to the
extent that such actions are taken on behalf of the Beneficial Holders.

       Section 5.8.  NOTICES TO CLEARING AGENCY.  Whenever notice or other
communication to the Certificateholders is required under this Agreement, unless
and until Definitive Certificates shall have been issued to the related
Certificateholders pursuant to Section 5.9, the Trustee shall give all such
notices and communications specified herein to be given to Holders of the
Book-Entry Certificates to the Clearing Agency which shall give such notices and
communications to the related DTC Participants in accordance with its applicable
rules, regulations and procedures.

       Section 5.9.  DEFINITIVE CERTIFICATES.  If (a) the Clearing Agency
notifies the Certificate Administrator, if any, or the Trustee that it is no
longer willing or able to discharge properly its responsibilities under the
Depositary Agreement with respect to the Book-Entry Certificates and the Trustee
or the Certificate Administrator is unable to locate a qualified successor, (b)
the Depositor, at its option, advises the Certificate Administrator, if any, or
the Trustee in writing that it elects to terminate the book-entry system with
respect to the Book-Entry Certificates through the Clearing Agency or (c) after
the occurrence of an Event of Default, Certificateholders holding Book-Entry
Certificates evidencing Percentage Interests aggregating not less than 66% of
the aggregate Class Principal Balance of such Certificates advise the
Certificate Administrator, if any, or the Trustee and the Clearing Agency
through DTC Participants in writing that the continuation of a book-entry system
with respect to the Book-Entry Certificates through the Clearing Agency is no
longer in the 



                                     82
<PAGE>

best interests of the Certificateholders with respect to such 
Certificates, the Trustee shall notify or cause to be notified all 
Certificateholders of Book-Entry Certificates of the occurrence of any 
such event and of the availability of Definitive Certificates.  Upon 
surrender to the Trustee of the Book-Entry Certificates by the Clearing 
Agency, accompanied by registration instructions from the Clearing 
Agency for registration, the Trustee shall execute and the Trustee or 
any Authenticating Agent shall authenticate and deliver the Definitive 
Certificates.  Neither the Depositor, the Certificate Administrator, if 
any, the Authenticating Agent 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.  Upon the 
issuance of Definitive Certificates for all of the Certificates all 
references herein to obligations imposed upon or to be performed by the 
Clearing Agency shall be deemed to be imposed upon and performed by the 
Trustee, the Certificate Administrator, if any, or to the extent 
applicable with respect to such Definitive Certificates, and the 
Trustee, the Certificate Administrator, the Certificate Registrar and 
the Paying Agent shall recognize the Holders of Definitive Certificates 
as Certificateholders hereunder.

       Section 5.10. OFFICE FOR TRANSFER OF CERTIFICATES.  The Trustee shall
maintain in New York, New York, an office or agency where Certificates may be
surrendered for registration of transfer or exchange.  First Trust of New York,
National Association, 100 Wall Street, Suite 1600, New York, New York 10005,
Attention:  Glenn Anderson, is initially designated for said purposes.


                                      ARTICLE VI

                            THE DEPOSITOR AND THE SERVICER

       Section 6.1.  LIABILITY OF THE DEPOSITOR AND THE SERVICER.  The Depositor
and the Servicer shall each be liable in accordance herewith only to the extent
of the obligations specifically imposed by this Agreement and undertaken
hereunder by the Depositor and the Servicer herein.

       Section 6.2.  MERGER OR CONSOLIDATION OF THE DEPOSITOR OR THE
SERVICER.  Subject to the following paragraph, the Depositor and the Servicer
each will keep in full effect its existence, rights and franchises as
corporations, each under the laws of the jurisdiction of its incorporation, 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, the
Certificates or any of the Loans and to perform its respective duties under this
Agreement.

       The Depositor or the Servicer 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 or Servicer shall be a party, or any Person succeeding to the business
of the Depositor or Servicer, shall be the successor of the Depositor or
Servicer 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.



                                     83
<PAGE>

       Section 6.3.  LIMITATION ON LIABILITY OF THE SERVICER AND 
OTHERS. Neither the Servicer nor any of the directors, officers, 
employees or agents of the Servicer 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 any director, officer, employee or agent of 
the Servicer against any liability which would otherwise be imposed by 
reason of willful misfeasance, bad faith or gross negligence in the 
performance of duties or by reason of reckless disregard of obligations 
and duties hereunder, nor shall this provision protect the Servicer 
against any liability that would otherwise be imposed by reason of 
negligence in the performance of duties hereunder.  The Servicer and 
any director, officer, employee or agent of the Servicer may rely in 
good faith on any document of any kind prima facie properly executed 
and submitted by any Person respecting any matters arising hereunder.  
The Servicer and any director, officer, employee or agent of the 
Servicer shall be indemnified by the Trust Fund and held harmless 
against any loss, liability or expense incurred in connection with any 
legal action relating to this Agreement or the Certificates, other than 
any loss, liability or expense, in the case of the Servicer and any 
director, officer, employee or agent of the Servicer, incurred by 
reason of willful misfeasance, bad faith or gross negligence in the 
performance of duties hereunder or by reason of reckless disregard of 
obligations and duties hereunder or, in the case of the Servicer, as 
Servicer, incurred by reason of negligence in the performance of any 
duties hereunder.  The Servicer shall not be under any obligation to 
appear in, prosecute or defend any legal action which is not incidental 
to its duties to service the Loans in accordance with this Agreement 
and which in its opinion may involve it in any expense or liability; 
PROVIDED, HOWEVER, that the Servicer may in its discretion undertake 
any such action which it may deem necessary or desirable in respect of 
this Agreement and the rights and duties of the parties hereto and the 
interests of the Certificateholders hereunder.  In such event, the 
legal expenses and costs of such action and any liability resulting 
therefrom shall be expenses, costs and liabilities of the Trust Fund, 
and the Servicer shall be entitled to be reimbursed therefor out of the 
Custodial Account for P&I as provided by Section 3.3.

       Section 6.4.  SERVICER NOT TO RESIGN.  The Servicer shall not resign from
the obligations and duties hereby imposed on it, except upon determination that
its duties hereunder are no longer permissible under applicable law or are in
material conflict by reason of applicable law with any other activities carried
on by it, the other activities of the Servicer so causing such a conflict being
of a type and nature carried on by the Servicer at the date of this Agreement. 
Any such determination permitting the resignation of the Servicer shall be
evidenced by an Opinion of Counsel to such effect delivered to the Trustee.  The
Servicer shall notify the Rating Agency of any such resignation.  No such
resignation shall become effective until a successor servicer shall have assumed
the Servicer's responsibilities and obligations in accordance with Section 7.5
hereof.

       Notwithstanding the limitations stated above, the Servicer may transfer
its obligations, duties and rights hereunder without the consent of the
Certificateholders, PROVIDED, that (i) the Servicer obtains the prior written
consent of the Rating Agency, (ii) the transferee is a FNMA- or FHLMC-approved
servicer having a net worth of not less than $15,000,000, (iii) the successor
servicer assumes all of the Servicer's responsibilities and obligations (except
the repurchase obligations set forth in Sections 2.2 and 2.3 hereof, which shall
remain obligations of the Depositor) in accordance 



                                     84
<PAGE>

with Section 7.5 hereof, and (iv) the then-current rating of the Class 
A Certificates will not be reduced as a result of such transfer, and 
(v) has, in the reasonable opinion of the Trustee, the qualifications, 
resources and experience to properly carry out, observe and perform the 
duties, obligations and responsibilities of Servicer hereunder; 
PROVIDED, that the foregoing clause (v) is intended solely for the 
benefit of (and may be exercised or waived at the sole discretion of) 
the Trustee, to enable the Trustee to assure itself that any successor 
Servicer has such acceptable qualifications, resources and experience, 
and such clause (v) is not intended to be for the benefit of, and shall 
not be relied upon or enforced by, any Certificateholder, and PROVIDED, 
FURTHER, that any consent to such transfer will not be unreasonably 
withheld by the Trustee.

                                 ARTICLE VII

                                   DEFAULT

       Section 7.1.  EVENTS OF DEFAULT.  In case one or more of the following
Events of Default by the Servicer shall occur and be continuing, that is to say:

              (i)    any failure by the Servicer to distribute or cause to be
       distributed to the Trustee or its delegate on the Withdrawal Date any
       payment required to be made to the Trustee under the terms of this
       Agreement.

              (ii)   any failure on the part of the Servicer duly to observe or
       perform in any material respect any other of the covenants or agreements
       on the part of the Servicer in the Certificates or in this Agreement
       which continues unremedied for a period of 60 days after the date on
       which written notice of such failure, requiring the same to be remedied,
       shall have been given to the Servicer by the Trustee, or to the Servicer
       and the Trustee by the Holders of Certificates evidencing, in aggregate,
       not less than 25% of the Trust Fund or 51% of the aggregate Percentage
       Interests of any class of certificates;

              (iii)  a decree or order of a court or agency or supervisory
       authority having jurisdiction in the premises for the appointment of a
       conservator or receiver or liquidator in any insolvency, readjustment of
       debt, marshalling of assets and liabilities or similar proceedings, or
       for the winding-up or liquidation of its affairs, shall have been entered
       against the Servicer and such decree or order shall have remained in
       force undischarged or unstayed for a period of 60 days;

              (iv)   the Servicer shall consent to the appointment of a
       conservator or receiver or liquidator or liquidating committee in any
       insolvency, readjustment of debt, marshalling of assets and liabilities,
       voluntary liquidation or similar proceedings of or relating to the
       Servicer or of or relating to all or substantially all of its property;

              (v)    the Servicer shall admit in writing its inability to pay
       its debts generally as they become due, file a petition to take advantage
       of any applicable insolvency or 





                                     85



<PAGE>


       reorganization statute, make an assignment for the benefit of its 
       creditors or voluntarily suspend payment of its obligations; or

              (vi)   any failure of the Servicer to make any Advance required to
       be made from its own funds pursuant to Section 4.3 which continues
       unremedied for a period of one Business Day after the date upon which
       such Advance was to have been made;

then, if an Event of Default described in clauses (i)-(v) of this Section 7.1
shall occur, and in each and every such case, subject to applicable law, so long
as an Event of Default shall not have been remedied, either the Trustee or the
Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust
Fund or 51% of the aggregate Percentage Interests of any Class of Certificates
by notice in writing to the Servicer (and to the Trustee if given by the
Certificateholders) may terminate all of the rights and obligations of the
Servicer under this Agreement, but without prejudice to any rights it may have
to reimbursement of expenses, Advances and other advances of its own funds as
Servicer to the extent permitted by this Agreement, other than the Depositor's
(or its successors') obligation to repurchase any Loans pursuant to Section 2.2
or 2.3 shall survive any such termination.  If an Event of Default described in
clause (vi) hereof shall occur, the Trustee shall, by notice in writing to the
Servicer, which shall be telecopied to the Servicer, immediately terminate all
of the rights and obligations of the Servicer, under this Agreement and in and
to the Loans and the proceeds thereof.  On or after the receipt by the Servicer
of such written notice, all authority and power of the Servicer under this
Agreement, whether with respect to the Certificates or the Loans or otherwise,
shall pass to and be vested in the Trustee pursuant to and under this Section
7.1 (subject to the provisions of Section 7.5); and, without limitation, the
Trustee is hereby authorized and empowered to execute and deliver, on behalf of
the Servicer, as attorney-in-fact or otherwise, any and all documents and other
instruments, and to do or accomplish all other acts or things necessary or
appropriate to effect the purposes of such notice of termination, whether to
complete the transfer and endorsement or assignment of the Loans and related
documents or otherwise at the expense of the Servicer.  The Servicer agrees to
cooperate with the Trustee in effecting the termination of the Servicer's
responsibilities and rights hereunder and shall promptly provide the Trustee all
documents and records whether in written or electronic form reasonably requested
by it to enable it to assume the Servicer's functions hereunder and shall
promptly also transfer to the Trustee of this Agreement all amounts which then
have been or should have been deposited in the Custodial Account for P&I by the
Servicer or which are thereafter received with respect to the Loans as well as
any escrowed funds held by it or in connection with its servicing activities
hereunder.  The Servicer and the Trustee shall give the Rating Agency notice of
any Event of Default.

       Section 7.2.  OTHER REMEDIES OF TRUSTEE.  During the continuance of any
Event of Default, so long as such Event of Default shall not have been remedied,
the Trustee, in addition to the rights specified in Section 7.1, shall have the
right, in its own name as trustee of an express trust, to take all actions now
or hereafter existing at law, in equity or by statute to enforce its rights and
remedies and to protect the interests, and enforce the rights and remedies, of
the Certificateholders (including the institution and prosecution of all
judicial, administrative and other proceedings and the filing of proofs of claim
and debt in connection therewith).  Except as otherwise expressly provided in
this Agreement, no remedy provided for by this Agreement shall be exclusive of
any other remedy, and 


                                  86
<PAGE>


each and every remedy shall be cumulative and in addition to any other remedy 
and no delay or omission to exercise any right or remedy shall impair any 
such right or remedy or shall be deemed to be a waiver of any Event of 
Default.

       Section 7.3.  DIRECTIONS BY CERTIFICATEHOLDERS AND DUTIES OF TRUSTEE
DURING EVENT OF DEFAULT.  During the continuance of any Event of Default,
Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust
Fund or 51% of the aggregate Percentage Interests of any Class of Certificates
may direct 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; PROVIDED, HOWEVER, that the Trustee shall be
under no obligation to pursue any such remedy, or to exercise any of the trusts
or powers vested in it by this Agreement (including, without limitation, (i) the
conducting or defending of any administrative action or litigation hereunder or
in relation hereto and (ii) the terminating of the Servicer or any successor
servicer from its rights and duties as servicer hereunder) at the request, order
or direction of any of the Certificateholders, 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; and,
PROVIDED, FURTHER, that, subject to the provisions of Section 8.1, the Trustee
shall have the right to decline to follow any such direction if the Trustee, in
accordance with an Opinion of Counsel, determines that the action or proceeding
so directed may not lawfully be taken or if the Trustee in good faith determines
that the action or proceeding so directed would involve it in personal liability
or be unjustly prejudicial to the non-assenting Certificateholders or if the
Trustee has received contrary directions pursuant to this Section 7.3.

       Section 7.4.  ACTION UPON CERTAIN FAILURES OF SERVICER AND UPON EVENT OF
DEFAULT.  In the event that the Trustee shall have knowledge of any failure of
the Servicer specified in Section 7.1(i) or (ii) which would become an Event of
Default upon the Servicer's failure to remedy the same after notice, the Trustee
shall give notice thereof to the Servicer.  In the event that the Trustee shall
have knowledge of an Event of Default, the Trustee shall give prompt written
notice thereof to the Certificateholders and to the Rating Agency.  For all
purposes of this Agreement, in the absence of actual knowledge by a Responsible
Officer of the Trustee, the Trustee shall not be deemed to have knowledge of any
failure of the Servicer as specified in Section 7.1(i) and (ii) or any Event of
Default unless notified thereof in writing by the Servicer or by a
Certificateholder.

       Section 7.5.  APPOINTMENT OF SUCCESSOR SERVICER.

              (a)    When the Servicer receives a notice of termination pursuant
       to Section 7.1 or the Trustee receives the resignation of the Servicer
       evidenced by an Opinion of Counsel pursuant to Section 6.4, the Trustee
       shall become the successor in all respects to the Servicer in its
       capacity as Servicer under this Agreement and the transactions set forth
       or provided for herein, PROVIDED, HOWEVER, that the Trustee's obligation
       to make any Advances shall be no greater than set forth in Section 4.3 of
       this Agreement, and the Trustee shall have all the rights and powers and
       be subject to all the responsibilities, duties and liabilities relating
       thereto placed on the Servicer by the terms and provisions hereof (except
       those contained in Sections 2.2 and 2.3) and in its capacity as such
       successor shall have the same limitation 


                                      87
<PAGE>


       of liability herein granted to the Servicer and PROVIDED, FURTHER, 
       that the Trustee shall not be required to make an Advance from its own 
       funds if such Advance would be prohibited by law.  As compensation 
       therefor, the Trustee shall be entitled to receive monthly an amount 
       not to exceed the Servicing Fee as agreed by the Trustee and the 
       Servicer, together with such other servicing compensation in the form 
       of assumption fees, late charges, prepayment fees or otherwise as 
       provided in Section 3.9.  If the agreed amount is less than the 
       Servicing Fee, the excess shall be paid to the Class R 
       Certificateholder.  If the Trustee and the Servicer shall not agree on 
       the amount of such compensation, the Trustee shall solicit bids for a 
       successor servicer as described in Section 7.5(b), PROVIDED, HOWEVER, 
       if no successor servicer is obtained through the bidding process, the 
       Trustee may act as such, or may pursuant to Section 7.5(b) appoint a 
       successor servicer to act as such, for the Servicing Fee together with 
       such other servicing compensation as provided in Section 3.9.  In no 
       event shall the Trustee's assumption of or succession to the 
       obligations of the Servicer make the Trustee liable for any actions or 
       omissions of the Servicer in its capacity as Servicer.

              (b)    Notwithstanding the above, the Trustee may and shall, if it
       is unable (or unwilling due to disagreement on compensation as provided
       in Section 7.5(a)) to act as Servicer, appoint, or petition a court of
       competent jurisdiction to appoint, any established housing and home
       finance institution, bank or mortgage servicing institution which is an
       approved FNMA or FHLMC servicer having a net worth of not less than
       $15,000,000 and meeting such other standards as are set forth in
       Section 6.4 hereof for a successor to the Servicer hereunder in the
       assumption of all or any part of the responsibilities, duties or
       liabilities of the Servicer hereunder (except the repurchase obligations
       set forth in Sections 2.2 and 2.3 hereof, which shall remain obligations
       of the Depositor); PROVIDED, HOWEVER, that until such appointment and
       assumption, the Trustee will continue to perform the servicing
       obligations pursuant to this Agreement (and until such time shall be
       entitled to receive the Servicing Fees pursuant to Section 3.9);
       PROVIDED, FURTHER, that prior to the appointment of any successor
       servicer, the Rating Agencies confirm that the appointment of such
       successor servicer would not result in the downgrade of the Rating
       assigned to any Class of Certificates.  The compensation of any successor
       servicer so appointed shall be equal to the Servicing Fees specified in
       Section 3.9 together with such other compensation as is provided in said
       Section 3.9.  In the event the Trustee is required to solicit bids as
       provided above, the Trustee shall solicit, by public announcement, bids
       from housing and home finance institutions, banks and mortgage servicing
       institutions acceptable to the Trustee and meeting the qualifications set
       forth above in this Section 7.5(b) for the purchase of the servicing
       functions.  Such public announcement shall specify that the successor
       servicer shall be entitled to the full amount of the Servicing Fee on the
       aggregate unpaid principal balance of the Loans as servicing compensation
       for servicing the Loans, together with the other servicing compensation
       in the form of assumption fees, late payment charges, prepayment fees or
       otherwise as provided in Section 3.9.  Within 45 days after any such
       public announcement, the Trustee shall negotiate and effect the sale,
       transfer and assignment of the servicing rights and responsibilities
       hereunder (except the repurchase obligations set forth in Section 2.2 and
       2.3 hereof, which shall remain obligations of the Depositor) to the
       qualified party submitting the highest qualifying bid.  The Trustee shall
       deduct all costs and 


                                        88
<PAGE>


       expenses of any public announcement and of any sale, transfer and 
       assignment of the servicing rights and responsibilities hereunder from 
       any sum received by the Trustee from the successor to the Servicer in 
       respect of such sale, transfer and assignment.  After such deductions, 
       the remainder of such sum shall be paid by the Trustee to the Class R 
       Certificateholder at the time of such sale, transfer and assignment to 
       the Servicer's successor.

              (c)    The Servicer agrees to cooperate with the Trustee and any
       successor servicer in effecting the termination of the Servicer's
       servicing responsibilities and rights hereunder and shall promptly
       provide the Trustee or such successor servicer, as applicable, all
       documents and records reasonably requested by it to enable it to assume
       the Servicer's functions hereunder and shall promptly also transfer to
       the Trustee or such successor servicer, as applicable, all amounts which
       then have been or should have been deposited in the Custodial Account for
       P&I by the Servicer or which are thereafter received with respect to the
       Loans.  Neither the Trustee nor any other successor servicer shall be
       deemed to be in default hereunder by reason of any failure to make, or
       any delay in making, any distribution hereunder or any portion thereof
       caused by the failure of the Servicer to deliver, or any delay in
       delivering, cash, documents or records to it.

       Section 7.6.  NOTIFICATION TO CERTIFICATEHOLDERS.  Upon any termination
of the Servicer or appointment of a successor to the Servicer, in each case as
provided herein, the Trustee shall as soon as practicable give written notice
thereof to Certificateholders at their respective addresses appearing in the
Certificate Register and the Rating Agency.


                                     ARTICLE VIII

                                CONCERNING THE TRUSTEE

       Section 8.1.  DUTIES OF TRUSTEE.  The Trustee, prior to the occurrence of
an Event of Default and after the curing of all Events of Default which may have
occurred, undertakes to perform such duties and only such duties as are
specifically set forth in this Agreement.  In case an Event of Default has
occurred (which has not been cured), the Trustee, subject to the provisions of
Sections 7.1, 7.3, 7.4 and 7.5, shall exercise such of the rights and powers
vested in it by this Agreement, and use the same degree of care and skill in
their exercise as a prudent person would exercise or use under the circumstances
in the conduct of such person's own affairs.  Any permissive right of the
Trustee enumerated in this Agreement shall not be construed as a duty.

       Subject to Sections 8.2(i), 8.3 and 8.4, 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; PROVIDED,
HOWEVER, that the Trustee shall not be responsible for the accuracy or content
of any resolution, certificate, statement, opinion, report, document, order or
other instrument furnished by any party hereunder.  If any such instrument is
found not to conform to the requirements of this Agreement 


                                        89
<PAGE>


in a material manner, the Trustee shall take action as it deems appropriate 
to have the instrument corrected, and if the instrument is not corrected to 
the Trustee's reasonable satisfaction, the Trustee will provide notice 
thereof to the Certificateholders and the Rating Agency.

       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 or in the event the Trustee is acting as successor
servicer pursuant to Section 7.5, to the standard imposed on the Servicer
pursuant to Section 6.3 of this Agreement; PROVIDED, HOWEVER, that:

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

              (ii)   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 this Agreement or at the direction of Certificateholders
       holding Certificates which have an aggregate Principal Balance not less
       than 25% of the aggregate Principal Balance of all Certificates relating
       to the time, method and place of conducting any proceeding for any remedy
       available to the Trustee, or exercising or omitting to exercise any trust
       or power conferred upon the Trustee, under this Agreement;

              (iii)  The Trustee shall not be liable in its individual capacity
       for any error of judgment made in good faith by any Responsible Officer,
       unless it shall be proved that the Trustee or such Responsible Officer
       was negligent in ascertaining the pertinent facts;

              (iv)   The Trustee shall not be liable for any act or omission of
       the Depositor or the Servicer (except for its own acts or omissions as
       Servicer hereunder) or for any but its own acts or omissions; 

              (v)    The Trustee shall not be deemed to take notice or be deemed
       to have knowledge of any matter, including without limitation any default
       or Event of Default, unless written notice thereof, referring to the
       Certificates, the Depositor, the Trust Fund or this Agreement is received
       by a Responsible Officer of the Trustee at its Corporate Trust Office;
       and

              (vi)   Subject to the other provisions of this Agreement and
       without limiting the generality of this Section 8.1, the Trustee shall
       have no duty (A) to see to any recording, filing, or depositing of this
       Agreement or any agreement referred to herein or any financing 


                                         90

<PAGE>

       statement or continuation statement evidencing a security interest, or 
       to see to the maintenance of any such recording or filing or 
       depositing or to any rerecording, refiling or redepositing of any 
       thereof, (B) to see to any insurance, (C) to see to the payment or 
       discharge of any tax, assessment, or other governmental charge or any 
       lien or encumbrance of any kind owing with respect to, assessed or 
       levied against, any part of the Trust Fund other than from funds 
       available in the Certificate Account, and (D) to confirm or verify the 
       contents of any reports or certificates of the Servicer delivered to 
       the Trustee pursuant to this Agreement believed by the Trustee to be 
       genuine and to have been signed or presented by the proper party or 
       parties.

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

       Section 8.2.  CERTAIN MATTERS AFFECTING TRUSTEE.  Except as otherwise
provided in Section 8.1:

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

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

              (iii)  The Trustee shall 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; 

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


                                         91
<PAGE>


              (v)    The Trustee shall not be required to give any bond or
       surety in respect of the execution of the Trust Fund created hereby or
       the powers granted hereunder; 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, attorneys or custodians, and the Trustee shall not be
       responsible for any misconduct or negligence on the part of any such
       agent, attorney or custodian appointed by the Trustee with care.  Any
       such agents, attorneys or custodians shall be entitled to all indemnities
       and protection afforded to the Trustee.  Any designee of the Trustee
       shall be considered its "agent" hereunder whether performing it as an
       independent contractor or otherwise.

       Section 8.3.  TRUSTEE NOT REQUIRED TO MAKE INVESTIGATION.  Prior to the
occurrence of an Event of Default hereunder and after the curing of all Events
of Default which may have occurred, the Trustee shall not be bound to ascertain
or inquire as to the performance or observance of any of the terms, conditions,
covenants or agreements herein or to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion,
report, notice, request, consent, order, approval, bond, Mortgage, Mortgage Note
or other paper or document, unless requested in writing so to do by Holders of
Certificates having a Percentage Interest not less than 51% of the Trust Fund;
PROVIDED, HOWEVER, that if the payment within a reasonable time to the Trustee
of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee, not reasonably assured
to the Trustee by the security afforded to it by the terms of this Agreement,
the Trustee may require reasonable indemnity against such expense or liability
as a condition to such proceeding.  The reasonable expense of every such
examination shall be paid by the Depositor or, if paid by the Trustee, shall be
repaid by the Depositor upon demand.

       Section 8.4.  TRUSTEE NOT LIABLE FOR CERTIFICATES OR LOANS.  The recitals
contained herein and in the Certificates (other than the certificate of
authentication on the Certificates) shall be taken as the statements of the
Depositor, and the Trustee assumes no responsibility for the correctness of the
same.  The Trustee makes no representations or warranties as to the validity or
sufficiency of this Agreement or of the Certificates or of any Loan or related
document.  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 Servicer in respect of
the Loans or deposited in or withdrawn from the Custodial Account for P&I by the
Servicer or for investment of any such amounts.  The Trustee shall not be
responsible for the legality or validity of this Agreement or the validity,
priority, perfection or sufficiency of the security for the Certificates issued
or intended to be issued hereunder.  The Trustee shall have no responsibility
for filing any financing or continuation statement in any public office at any
time or to otherwise perfect or maintain the perfection of any security interest
or lien granted to it hereunder or to record this Agreement.

       Neither the Trustee nor any of the directors, officers, employees or
agents of the Trustee 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 


                                         92
<PAGE>


judgment while an Event of Default exists; PROVIDED, HOWEVER, that this 
provision shall not protect the Trustee or any such person against any 
liability which would otherwise be imposed by reason of willful misfeasance, 
bad faith or negligence in the performance of duties.  The Trustee and any 
director, officer, employee or agent of the Trustee shall be indemnified by 
the Depositor and held harmless against any loss, liability or expense, 
including reasonable attorneys' fees, incurred in connection with or related 
to the Trustee's performance of its powers and duties under this Agreement 
(including, without limitation, performance under Section 8.1 hereof), or any 
action relating to this Agreement or the Certificates, or the performance of 
the Trustee's duties hereunder, other than any loss, liability or expense 
incurred by any such Person by reason of willful misfeasance, bad faith or 
negligence in the performance of duties.  Any such losses, liabilities and 
expenses resulting therefrom shall be losses, liabilities and expenses of the 
Depositor.  The indemnification provided hereunder shall survive termination 
of this Agreement.

       Section 8.5.  TRUSTEE MAY OWN CERTIFICATES.  The Trustee and any agent of
the Trustee in its individual or any other capacity may become the owner of or a
pledgee of the Certificates with the same rights it would have if it were not
Trustee or such agent, and may otherwise deal with the parties hereto.

       Section 8.6.  SERVICER TO PAY TRUSTEE'S FEES AND EXPENSES.  The Servicer
covenants and agrees to pay to the Trustee monthly (or as otherwise agreed), and
the Trustee shall be entitled to receive, reasonable compensation (which shall
not be limited by any provision of law in regard to the compensation of a
trustee of an express trust) for all services rendered by it in the execution of
the trusts hereby created and in the exercise and performance of any of the
powers and duties hereunder of the Trustee, and the Servicer shall pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances, including reasonable attorneys' fees, incurred or
made by the Trustee in accordance with any of the provisions of this Agreement
(including the reasonable compensation and the expenses and disbursements of its
counsel and of all persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith.  The Tax
Matters Person (or Person acting as its attorney-in-fact or agent) shall
indemnify the Trustee for any liability of or assessment against the Trustee
resulting from any error in any tax or tax information returns prepared or
caused to be prepared by such Person.  In the event that (i) the Servicer does
not pay to the Trustee any compensation owed to the Trustee pursuant to this
Agreement or (ii) the Trustee is not reimbursed for any expense, disbursement or
advance incurred or made by the Trustee pursuant to this Agreement, the Trustee
shall be entitled to withdraw and retain such amount from the Certificate
Account.  In the event the Trustee incurs expenses or renders services in any
proceedings which result from an Event of Default under Section 7.1, subsections
(iii), (iv) or (v) of this Agreement, or from any default which, with the
passage of time, would become an Event of Default, the expenses so incurred and
compensation for services so rendered are intended to constitute expenses of
administration under the United States Bankruptcy Code or equivalent law.

       Section 8.7.  ELIGIBILITY REQUIREMENTS FOR TRUSTEE.  The Trustee
hereunder shall at all times be a corporation or association organized and doing
business under the laws of any state of the United States of America, authorized
under such laws to exercise corporate trust powers, having a 


                                   93
<PAGE>


combined capital and surplus of at least $50,000,000 and subject to 
supervision or examination by federal or state authority.  The Trustee shall 
not control the Servicer nor be a parent of or a subsidiary of the Servicer.  
If such corporation or association publishes reports of condition at least 
annually, pursuant to law or to the requirements of the aforesaid supervising 
or examining authority, then for the purposes of this Section 8.7 the 
combined capital and surplus of such corporation or association shall be 
deemed to be its combined capital and surplus as set forth in its most recent 
report of condition so published.  In case at any time the Trustee shall 
cease to be eligible in accordance with the provisions of this Section 8.7, 
the Trustee shall resign immediately in the manner and with the effect 
specified in Section 8.8.

       Section 8.8.  RESIGNATION AND REMOVAL OF TRUSTEE.  The Trustee may at any
time resign and be discharged from the trusts hereby created by giving written
notice of resignation to the Servicer.  Such notice shall also be furnished to
the Rating Agency.  Upon receiving such notice of resignation, the Servicer
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 at the expense of the
Servicer.

       If at any time the Trustee shall cease to be eligible in accordance with
the provisions of Section 8.7 and shall fail to resign after written request for
the Trustee's resignation by the Servicer, 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,
with or without cause, the Servicer 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.

       The Holders of Certificates having a Percentage Interest aggregating not
less than 51% of the aggregate Denomination of all Certificates 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 instrument or instruments shall be
delivered to the Servicer, one complete set to the Trustee so removed and one
complete set to the successor trustee so appointed.

       Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 8.8 shall become
effective only upon acceptance of appointment by the successor trustee as
provided in Section 8.9.

       Section 8.9.  SUCCESSOR TRUSTEE.  Any successor trustee appointed as
provided in Section 8.8 shall execute, acknowledge and deliver to the Servicer
and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee
shall become effective, and such successor trustee, without any further act,
deed or conveyance, shall become fully vested with all the rights, powers,
duties and obligations of its 


                                       94
<PAGE>


predecessor hereunder, with like effect as if originally named as trustee 
herein.  The predecessor trustee shall deliver or cause to be delivered to 
the successor trustee all Mortgage Files and related documents and statements 
held by it hereunder (other than any Mortgage Files at the time held by the 
Custodian, if it shall agree to become the agent of any successor trustee 
hereunder), and the Servicer and the predecessor trustee shall execute and 
deliver such instruments and do such other things as may reasonably be 
required for more fully and certainly vesting and confirming in the successor 
trustee all such rights, powers, duties and obligations.

       No successor trustee shall accept appointment as provided in this Section
8.9 unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 8.7.

       Upon acceptance of appointment by a successor trustee as provided in this
Section 8.9, the Servicer shall mail notice of the succession of such trustee
hereunder to all holders of Certificates at their addresses as shown in the
Certificate Register and to the Rating Agency.  If the Servicer fails to mail
such notice within ten days after acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Servicer.

       Section 8.10. MERGER OR CONSOLIDATION OF TRUSTEE.  Any Person into which
the Trustee may be merged or converted or with which it may be consolidated, or
any Person resulting from any merger, conversion or consolidation to which the
Trustee shall be a party, or any Person succeeding to all or substantially all
of the corporate trust business of the Trustee, shall be the successor of the
Trustee hereunder, PROVIDED, that such Person shall be eligible under the
provisions of Section 8.7, 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 8.11. APPOINTMENT OF CO-TRUSTEE OR SEPARATE TRUSTEE. 
Notwithstanding any other provisions hereof, at any time, for the purpose of
meeting any legal requirements of any jurisdiction in which any part of the
Trust Fund or property securing the same may at the time be located, the
Servicer and the Trustee acting jointly shall have the power and shall execute
and deliver all instruments to appoint one or more Persons approved by the
Trustee to act as co-trustee or co-trustees, jointly with the Trustee, or
separate trustee or separate trustees, of all or any part of the Trust Fund, and
to vest in such Person or Persons, in such capacity, such title to the Trust
Fund, or any part thereof, and, subject to the other provisions of this
Section 8.11, such powers, duties, obligations, rights and trusts as the
Servicer and the Trustee may consider necessary or desirable.  If the Servicer
shall not have joined in such appointment within 15 days after the receipt by it
of a request so to do, or in case an Event of Default shall have occurred and be
continuing, the Trustee alone shall have the power to make such appointment. 
Each co-trustee or separate trustee hereunder shall not be required to meet the
terms of eligibility as a successor trustee under Section 8.7 hereunder but no
notice to holders of Certificates of the appointment of co-trustee(s) or
separate trustee(s) shall be required under Section 8.9 hereof.

       In the case of any appointment of a co-trustee or separate trustee
pursuant to this Section 8.11, all rights, powers, duties and obligations
conferred or imposed upon the Trustee shall be conferred or imposed upon and
exercised or performed by the Trustee and such separate trustee 


                                     95

<PAGE>

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

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

       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.  The Trustee shall not be responsible
for any action or inaction of any such separate trustee or co-trustee.  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.

       The Trustee may appoint one or more Eligible Institutions to act as its
agent or agents to perform any or all of its duties and obligations under this
Agreement.  Each such agent shall be subject to all of 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.

       Section 8.12. APPOINTMENT OF CUSTODIANS. The Trustee may, with the
consent of the Servicer, appoint one or more Custodians, not affiliated with the
Depositor, to review, pursuant to Section 2.2 hereof, and hold all or a portion
of the Mortgage Files as agent for the Trustee PROVIDED, HOWEVER, that such
appointed Custodian may be LaSalle National Bank.  Any Custodian appointed shall
be an institution subject to supervision by federal or state authority, shall
have combined capital and surplus of at least $50,000,000 and shall be qualified
to do business in the jurisdiction in which it holds any Mortgage File.

       Section 8.13. AUTHENTICATING AGENT.

              (a)    The Trustee may appoint from time to time an authenticating
       agent (the "Authenticating Agent") which shall be authorized to act on
       behalf of the Trustee in authenticating Certificates.  Wherever reference
       is made in this Agreement to the 


                                       96

<PAGE>

       authentication of Certificates by the Trustee or the Trustee's 
       certificate of authentication, such reference shall be deemed to include
       authentication on behalf of the Trustee by the Authenticating Agent and
       a certificate of authentication executed on behalf of the Trustee by the
       Authenticating Agent.  Any successor Authenticating Agent must be 
       acceptable to the Servicer and have a principal office and place of
       business in New York, New York or Chicago, Illinois, have a combined 
       capital and surplus of at least $50,000,000, and be authorized to do a 
       trust business and subject to supervision or examination by federal or
       state authorities.

              (b)    Any corporation into which the Authenticating Agent may be
       merged or converted or with which it may be consolidated, or any
       corporation resulting from any merger, conversion or consolidation to
       which the Authenticating Agent shall be a party, or any corporation
       succeeding to all or substantially all of the corporate agency business
       of the Authenticating Agent, shall continue to be the Authenticating
       Agent without the execution or filing of any paper or any further act on
       the part of the Trustee or the Authenticating Agent.

              (c)    The Authenticating Agent may at any time resign by giving
       at least 30 days' advance written notice of resignation to the Trustee
       and to the Servicer.  The Trustee may at any time terminate the agency of
       the Authenticating Agent by giving written notice of termination to the
       Authenticating Agent and to the Servicer.  Upon receiving a notice of
       resignation or upon such a termination, or in case at any time the
       Authenticating Agent shall cease to be eligible in accordance with the
       provisions of this Section 8.13, the Trustee promptly shall appoint a
       successor Authenticating Agent, shall give written notice of such
       appointment to the Servicer and shall mail notice of such appointment to
       all Certificateholders.  Any successor Authenticating Agent upon
       acceptance of its appointment hereunder shall become vested with all the
       rights, powers, duties and responsibilities of its predecessor hereunder,
       with like effect as if originally named as Authenticating Agent herein. 
       No successor Authenticating Agent shall be appointed unless eligible
       under the provisions of this Section 8.13.

              (d)    The Authenticating Agent shall have no responsibility or
       liability for any action taken by it as such at the direction of the
       Trustee.  Any reasonable compensation paid to the Authenticating Agent
       shall be a reimbursable expense under Section 8.6.

       Section 8.14. BLOOMBERG.  As soon as practicable after the Closing Date,
the Trustee or the Certificate Administrator, if any, will arrange with 
Bloomberg to have the Depositor set up on Bloomberg to provide the information
set forth on Exhibit Q (the "Data") with respect to the Loans on a monthly basis
in a format acceptable to Bloomberg and acceptable to the Underwriters.  During
the term of this Agreement,  the Trustee will provide updated Data to Bloomberg
on or before each Distribution Date.

       Section 8.15.  REPORTS TO SECURITIES AND EXCHANGE COMMISSION. Unless
otherwise directed by the Depositor in writing, the Certificate Administrator or
the Trustee, as applicable, shall prepare, 


                                       97

<PAGE>

sign and file with the Securities and Exchange Commission, on behalf of the 
Depositor, (i) no later than ten days after each Distribution Date, the 
Certificateholders' Report on the appropriate form and in the appropriate 
medium authorized or prescribed therefor under the Exchange Act , (ii) no 
later than March 15 of each calendar year, an annual report meeting the 
requirements of the Exchange Act on the appropriate form and in the 
appropriate medium authorized or prescribed therefor under the Exchange Act.  
The Trustee or the Certificate Administrator, as applicable, shall promptly 
forward copies of all filings made pursuant to this Section 8.15 to the 
Depositor.  

                                      ARTICLE IX

                                     TERMINATION

       Section 9.1.  TERMINATION UPON PURCHASE BY THE DEPOSITOR OR LIQUIDATION
OF ALL LOANS.  The respective obligations and responsibilities of the Servicer
and the Trustee created hereby (other than the obligation to make payments to
Certificateholders as hereafter set forth in this Section 9.1 and obligations to
the Trustee in Sections 8.4 and 8.6) shall terminate upon the earlier of (i) the
later of the final payment or other liquidation (or any Advance with respect
thereto) of the last Loan remaining in the Trust Fund and the disposition of all
property acquired in respect of any Loan or (ii) the purchase by the Depositor
of all Loans at a price equal to the sum of (a) the principal balance of each
Loan plus accrued interest thereon at the applicable Pass-Through Rate to the
next scheduled Installment Due Date, less any Nonrecoverable Advances made with
respect to any such Loans and (b) the fair market value of all acquired property
in respect of Loans, less any Nonrecoverable Advances made with respect to any
such Loans, such fair market value to be determined by an appraiser selected by
the Trustee or (iii) the purchase by the Servicer, so long as the Servicer is
the Depositor, of all outstanding Certificates and delivery of such Certificates
to the Trustee; PROVIDED, HOWEVER, that in no event shall the trust created
hereby continue beyond the expiration of 21 years from the death of the last
survivor of the descendants of Joseph P. Kennedy, the late ambassador of the
United States to the Court of St. James, living on the date hereof; and
PROVIDED, FURTHER, that a "plan of liquidation" of each of REMIC I and II in
accordance with Section 860F of the Code must be adopted in conjunction with any
termination effected pursuant to subclauses (i), (ii), or (iii) of this
Section 9.1.

       The Depositor is hereby granted the right to purchase the Loans pursuant
to clause (ii) above, PROVIDED, HOWEVER, that such right shall be conditioned
upon the Principal Balances of such Loans, at the time of any such purchase,
aggregating an amount less than 10% of the aggregate Principal Balance of the
Loans on the Cut-off Date, after deduction of payments due on or before such
date.

       Notice of any termination pursuant to clause (i) or (ii) above,
specifying the Distribution Date upon which all Certificateholders may surrender
their Certificates to the Trustee or its agent for payment and cancellation,
shall be given promptly by the Trustee or its agent (upon direction by the
Servicer no less than 10 days prior to the date such notice is to be mailed) by
letter to Certificateholders and the Rating Agency mailed by first class mail no
later than the 25th day of the month preceding the month of such final
distribution specifying (i) the Distribution Date upon which 


                                       98

<PAGE>

final payment on the Certificates will be made upon presentation and 
surrender of Certificates at the office or agency of the Trustee or the 
Certificate Registrar therein designated, (ii) the amount of any such final 
payment and (iii) that the Record Date otherwise applicable to such 
Distribution Date is not applicable, payments being made only upon 
presentation and surrender of the Certificates at the office or agency of the 
Trustee or the Certificate Registrar therein specified. The Trustee or its 
agent shall give such notice to the Certificate Registrar and the Rating 
Agency at the time such notice is given to the Certificateholders. Upon any 
such termination, the duties of the Certificate Registrar shall also 
terminate.  In the event such notice is given in connection with the 
Depositor's election to purchase, the Depositor shall deposit in the 
Certificate Account on the related Withdrawal Date an amount equal to the 
above-described purchase price and upon such deposit Certificateholders will 
be entitled to the amount of such purchase price but not amounts in excess 
thereof, all as provided herein. Upon presentation and surrender of the 
Certificates pursuant to any termination under this Section 9.1, the Trustee 
or Paying Agent shall cause to be distributed to Certificateholders an amount 
equal to (a) the amount otherwise distributable on such Distribution Date, if 
not in connection with a purchase; or (b) if the Depositor elected to so 
purchase, the purchase price calculated as above provided.  Upon any 
termination pursuant to clause (iii) above, or upon certification to the 
Trustee by a Servicing Officer following such final deposit, the Trustee and 
any Custodians shall promptly release to the Servicer the Mortgage Files for 
the remaining Loans, and the Trustee shall execute all assignments, 
endorsements and other instruments necessary to effectuate such transfer.

       In the event that all of the Certificateholders shall not surrender their
Certificates for cancellation within three months after the time specified in
the above-mentioned written notice, the Trustee or its agent shall give a second
written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto.  If within three months after the second notice all the Certificates
shall not have been surrendered for cancellation, the Trustee or its agent shall
take appropriate and reasonable steps as directed by the Servicer, to contact
the remaining Certificateholders concerning surrender of their Certificates, and
the cost thereof shall be paid out of the funds and other assets which remain in
trust hereunder.

       Section 9.2.  TRUSTS IRREVOCABLE.  Except as expressly provided herein,
all trusts created hereby are irrevocable.

       Section 9.3.  ADDITIONAL TERMINATION REQUIREMENTS.

              (a)    In the event the Depositor exercises its purchase option as
       provided in Section 9.1, the Trust Fund shall be terminated in accordance
       with the following additional requirements, unless the Trustee and the
       Certificate Administrator have received an Opinion of Counsel to the
       effect that the failure of the Trust Fund to comply with the requirements
       of this Section 9.3 will not (i) result in the imposition of taxes on
       "prohibited transactions" of REMIC I or REMIC II of the Trust Fund as
       described in Section 860F(a)(2) of the Code, or (ii) cause either REMIC I
       or REMIC II of the Trust Fund to fail to qualify as a REMIC at any time
       that any Certificates are outstanding:


                                       99

<PAGE>

                     (A)    Within 90 days prior to the final Distribution Date
              set forth in the notice given by the Depositor under Section 9.1,
              the Tax Matters Person shall prepare the documents associated with
              and shall adopt a plan of complete liquidation of each of REMIC I
              and REMIC II of the Trust Fund; and

                     (B)    At or after the time of adoption of such a plan of
              complete liquidation and at or prior to the final Distribution
              Date, the Servicer as agent of the Trustee shall sell all of the
              assets of the Trust Fund to the Depositor for cash in accordance
              with such plan of liquidation; PROVIDED, HOWEVER, that in the
              event that a calendar quarter ends after the time of adoption of
              such a plan of complete liquidation but prior to the final
              Distribution Date, the Servicer shall not sell any of the assets
              of the Trust Fund prior to the close of that calendar quarter.

              (b)    The Tax Matters Person hereby agrees to adopt such a plan
       of complete liquidation and to take such other action in connection
       therewith as may be reasonably requested by the Servicer.


                                      ARTICLE X

                               MISCELLANEOUS PROVISIONS

       Section 10.1. AMENDMENT.  This Agreement may be amended from time to time
by the Depositor and the Trustee, without the consent of any of the
Certificateholders, (a) to cure any ambiguity, to correct or supplement any
provision herein which may be inconsistent with any other provision herein, or
to make any other provisions with respect to matters or questions arising under
this Agreement, or (b) to modify, eliminate or add to any provisions to such
extent as shall be necessary to maintain the qualification of the Trust Fund as
a REMIC at all times that any Class A or Subordinate Certificates are
outstanding, PROVIDED, that the Trustee has received an Opinion of Counsel to
the effect that such action is necessary or desirable to maintain such
qualification, PROVIDED, that such action under clauses (a) and (b) above shall
not, as evidenced by an Opinion of Counsel, adversely affect in any material
respect the interests of any Certificateholder.

       This Agreement may also be amended from time to time by the Depositor and
the Trustee with the consent of the Holders of Certificates evidencing, in
aggregate, not less than 50% of the Trust Fund for the purpose of adding any
provisions or changing in any manner or eliminating any of the provisions of
this Agreement or of modifying in any manner the rights of the Holders of
Certificates; PROVIDED, HOWEVER, that no such amendment shall (a) reduce in any
manner the amount of, or delay the timing of, payments received on Loans which
are required to be distributed in respect of any Certificate without the consent
of the Holder of such Certificate; (b) adversely affect in any material respect
the interest of the Holders of the Class A Certificates in a manner other 
than as described in (a) above without the consent of the Holders of Class A 
Certificates aggregating not less than 66-22/3% of the aggregate Percentage 
Interest evidenced by all Class A Certificates; (c) adversely affect in any 
material respect the interest of the Holders of the Subordinate Certificates
in a manner other than as described in (a) above without the consent of the 
Holders of Class A Certificates aggregating not less than 66-2/3% of the 
aggregate Percentage Interest evidenced by all Class A Certificates; (c) 
adversely affect in any material respect the interest of the Holders of the 
Subordinate Certificates 


                                      100
<PAGE>

in a manner other than as described in clause (a) above without the consent 
of the Holders of Subordinate Certificates aggregating not less than 66-2/3% 
of the aggregate Percentage Interest evidenced by all Subordinate 
Certificates; (d) adversely affect in any material respect the interest of 
the Class R Certificateholder without the consent of the Holders of the Class 
R Certificate; (e) change in any material respect the rights and obligations 
of the Servicer or successor Servicer under this Agreement without the prior 
written consent of such party; or (f) reduce the aforesaid percentage of the 
Certificates the Holders of which are required to consent to any such 
amendments without the consent of the Holders of all Certificates then 
outstanding; PROVIDED, that for the purposes of this Agreement, the Holder of 
the Class R Certificate shall have no right to vote at all times that any 
Class A or Subordinate Certificates are outstanding if such amendment relates 
to the modification, elimination or addition of any provision necessary to 
maintain the qualification of the Trust Fund as a REMIC.

       Notwithstanding any contrary provision of this Agreement, the Trustee
shall not consent to any amendment to this Agreement unless it shall have first
received an Opinion of Counsel to the effect that such amendment will not cause
either REMIC I or REMIC II of the Trust Fund to fail to qualify as a REMIC at
any time that any REMIC I Regular Interests or REMIC II Certificates are
outstanding.

       As soon as practicable after the execution of any such amendment, the
Trustee shall furnish written notification of the substance of such amendment to
each Certificateholder and the Rating Agency.

       It shall not be necessary for the consent of the Certificateholders under
this Section 10.1 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.

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

       Section 10.2. RECORDATION OF AGREEMENT.  This Agreement (or an abstract
hereof, if acceptable by the applicable recording office) is subject to
recordation in all appropriate public offices for real property records in all
the counties or other comparable jurisdictions in which any or all of the
properties subject to the Mortgages are situated, and in any other appropriate
public recording office or elsewhere, such recordation to be effected by the
Servicer at its expense, but only after the Depositor has delivered to the
Trustee an Opinion of Counsel to the effect that such recordation materially and
beneficially affects the interests of the Certificateholders.


                                      101

<PAGE>

       For the purpose of facilitating the recordation of this Agreement as
herein provided and for other purposes, this Agreement may be executed
simultaneously in any number of counterparts, each of which counterparts shall
be deemed to be an original, and such counterparts shall constitute but one and
the same instrument.

       Section 10.3. LIMITATION ON RIGHTS OF CERTIFICATEHOLDERS.  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 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.

       Except as otherwise expressly provided herein no Certificateholder,
solely by virtue of its status as a Certificateholder, shall have any right to
vote or in any manner otherwise control the operation and management of the
Trust Fund, or the obligations of the parties hereto, nor shall anything herein
set forth, or contained in the terms of the Certificates, be construed so as to
constitute the Certificateholders from time to time as partners or members of an
association, nor shall any Certificateholder be under any liability to any third
person by reason of any action taken by the parties to this Agreement pursuant
to any provision hereof.

       No Certificateholder, solely by virtue of its status as
Certificateholder, shall have any right by virtue or by availing of any
provision of this Agreement to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Agreement, unless such
holder previously shall have given to the Trustee a written notice of default
and of the continuance thereof, as hereinbefore provided, and unless all of the
Holders of Certificates evidencing, in aggregate, not less than 25% of the Trust
Fund shall have made written request upon the Trustee to institute such action,
suit or proceeding in its own name as Trustee hereunder and shall have offered
to the Trustee such reasonable indemnity as it may require against the costs,
expenses and liabilities to be incurred therein or thereby, and the Trustee, for
60 days after its receipt of such notice, request and offer of indemnity, shall
have neglected or refused to institute any such action, suit or proceeding; it
being understood and intended, and being expressly covenanted by each
Certificateholder with every other Certificateholder and the Trustee, that no
one or more holders of Certificates shall have any right in any manner whatever
by virtue or by availing of any provision of this Agreement to affect, disturb
or prejudice the rights of the Holders of any other of such Certificates, or to
obtain or seek to obtain priority over or preference to any other such Holder,
or to enforce any right under this Agreement, except in the manner herein
provided and for the benefit of all Certificateholders.  For the protection and
enforcement of the provisions of this Section 10.3, each and every
Certificateholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

       Section 10.4. GOVERNING LAW; JURISDICTION.  THIS AGREEMENT SHALL BE
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD
TO CONFLICTS OF LAWS PRINCIPLES), AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF
THE PARTIES HEREUNDER SHALL BE DETERMINED IN ACCORDANCE WITH SUCH LAWS.

       Section 1.    Definitions.  Each capitalized term used herein and not

connection with the proposed transfer, the Purchaser represents and warrants to

<PAGE>

       (c)    The Purchaser is an "accredited investor" as such term is

knowledge of financial and business matters and is capable of evaluating the 
merits and risks of an investment in the Purchased Certificates; the

considered necessary to make an informed investment decision; and the 
Purchaser is able to bear the economic risk of an investment in the Purchased 
Certificates and can afford a complete loss of such investment;

       (d)    The Purchaser is not affiliated with the Trustee;

       (e)    The Purchaser confirms that AMAC has made available to the

AMAC nor the Trust is under any obligation to register the Purchased 
Certificates or make an exemption available.  In the event that such a 
transfer is to be made within two years from the Closing Date without 
registration  under the Act or applicable state securities laws, (i) the 
Trustee or the Certificate Registrar shall require, in order to assure 
compliance with such laws, that the Certificateholder's prospective 
transferees each certify to AMAC, the Certificate Registrar and the Trustee

relied upon, and (ii) the Trustee, the Certificate Registrar or AMAC may 
require an Opinion of Counsel that such transfer may be made pursuant to an 
exemption from the Act and state securities laws, which Opinion of Counsel 
shall not be an expense of the Trustee, the Certificate Registrar or AMAC.  
Any such Certificateholder desiring to effect such transfer shall, and does 
hereby agree to, indemnify the Trustee and AMAC against any liability that 
may result if the Transfer is not so exempt or is not made in accordance with 
such federal and state laws.

       (b)    No transfer of a Purchased Certificate shall be made unless the 
transferee provides AMAC, the Certificate Registrar and the Trustee with (i) 
a Transferee's Agreement, substantially in the form of this Agreement, and 
(ii) an affidavit substantially in the form of Exhibit A hereto that the 
proposed transferee (x) is not an employee benefit plan or other plan or 
arrangement subject to the prohibited transaction provisions of ERISA or

Corporation, as depositor (the "Company"), LaSalle Home Mortgage Corporation, as
servicer (the "Servicer"), and Chase Bank of Texas, National Association, as
trustee (the "Trustee").  All terms used herein and not otherwise defined shall
have the meanings set forth in the Pooling and Servicing Agreement.  The Seller
hereby certifies, represents and warrants to, and covenants with the Depositor,
the Servicer, the Certificate Registrar and the Trustee that:

       1.     No purpose of the Seller relating to the sale of the Certificate

affidavit and agreement in the form attached to the Pooling and Servicing
Agreement as Exhibit J.  The Seller does not know or believe that any
representation contained therein is false.

       3.     The Seller has no actual knowledge that the Proposed Transferee is

       5.     The Seller has conducted a reasonable investigation of the
financial condition of the Purchaser and, as a result of the investigation ,
found that the Purchaser has historically paid its debts as they came due, and
found no significant evidence to indicate that the Purchaser will not continue
to pay its debts as they come due in the future.

       6.     The Purchaser has represented to the Seller that, if the
Certificates constitute a noneconomic residual interest, it (i) understands that
as holder of a noneconomic residual interest it may incur tax liabilities in
excess of any cash flows generated by the interest, and (ii) intends to pay
taxes associated with its holding of the Certificates as they become due.

                                          Very truly yours,

STATE OF      )
              )      ss:
COUNTY OF     )

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

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

       2.     That the Owner (i) is not and will not be a "disqualified
organization" as of the [date of transfer] within the meaning of Section 860E(e)
(5) of the Internal Revenue Code of 1986, as amended (the "Code") and will
endeavor to remain other than a disqualified organization for so long as it
retains its ownership interest in the Class R Certificate, and (ii) is acquiring
the Class R Certificate for its own account or for the account of another Owner
from which it has received an affidavit and agreement in substantially the same
form as this affidavit and agreement.  (For this purpose, a "disqualified
organization" means the United States, any state or political subdivision
thereof, or any agency or instrumentality of any of the foregoing (other than an
instrumentality all of the activities of which are subject to tax and, except
for the Federal Home Loan Mortgage Corporation, a majority of whose board of
directors is not selected by any such governmental entity, or any foreign
government or international organization, or any agency or instrumentality of
such foreign government or organization, any rural electric or telephone
cooperative, or any organization (other than certain farmers' cooperatives) that
is generally exempt from federal income tax unless such organization is subject
to the tax on unrelated business taxable income).

       3.     That the Owner is aware (i) of the tax that would be imposed on
transfers of the Class R Certificate; (ii) that such tax would be on the
transferor, or, if such transfer is through an agent (which person includes a
broker, nominee or middleman) for a disqualified organization, on the agent;
(iii) that the person otherwise liable for the tax shall be relieved of
liability for the tax if the transferee furnished to such person an affidavit
that the transferee is not a disqualified organization and, at the time of
transfer, such person does not have actual knowledge that the affidavit is
false; and (iv) that the Class R Certificate may represent "noneconomic residual
interests" within the meaning of Treasury regulations promulgated pursuant to
the Code and that the transferor of a noneconomic residual interest will remain
liable for any taxes due with respect to the income on such residual interest,
if a significant purpose of the transfer was to enable the transferor to impede
the assessment or collection of tax.

       4.     That the Owner is aware of the tax imposed on a "pass-through
entity" holding the Class R Certificate if at any time during the taxable year
of the pass-through entity a disqualified 


                                      J-1
<PAGE>

organization is the record holder of an interest in such entity.  (For this 
purpose, a "pass-through entity" includes a regulated investment company, a 
real estate investment trust or common trust fund, a partnership, trust or 
estate, and certain cooperatives.)

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

       6.     That the Owner has reviewed the restrictions set forth on the 
face of the Class R Certificate and the provisions of Section 5.1 of the 
Pooling and Servicing Agreement under which the Class R Certificate was 
issued.  The Owner expressly agrees to be bound by and to comply with such 
restrictions and provisions.

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

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

       9.     That no purpose of the Owner relating to the purchase of the 
Class R Certificate by the Owner is or will be to enable the transferor to 
impede the assessment or collection of tax.

       10.    That the Owner has no present knowledge or expectation that it 
will be unable to pay any United States taxes owed by it so long as any of 
the Certificates remain outstanding.

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

       12.    That the purpose of the Owner relating to any sale of the Class 
R Certificate by the Owner will be to impede the assessment or collection of 
tax.

       13.    The Owner is a citizen or resident of the United States, a 
corporation, partnership or other entity created or organized in, or under 
the laws of, the United States or any political subdivision thereof, or an 
estate or trust whose income from sources without the United States is 
includible in gross income for United States federal income tax purposes 
regardless of its connection with the conduct of a trade or business within 
the United States.

       14.    The Owner hereby agrees to cooperate with the Depositor and to 
take any action required of it by the Code or Treasury regulations thereunder 
(whether now or hereafter promulgated) in order to create or maintain the 
REMIC status of the REMIC I or the REMIC II.


                                      J-2
<PAGE>

       15.    The Owner hereby agrees that it will not take any action that 
could endanger the REMIC status of the REMIC I or the REMIC II, as 
applicable, or result in the imposition of tax on the REMIC I or the REMIC II 
unless counsel for, or acceptable to, the Depositor has provided an opinion 
that such action will not result in the loss of such REMIC status or the 
imposition of such tax, as applicable.

       16.    The Owner as transferee of the Class R Certificate has 
represented to their transferor that, if the Class R Certificate represents 
noneconomic residual interests, the Owner (i) understands that as holder of a 
noneconomic residual interest it may incur tax liabilities in excess of any 
cash flows generated by the interest, and (ii) intends to pay taxes 
associated with its holding of the Class R Certificate as they become due.

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

                       FORM OF ADDITIONAL MATTER INCORPORATED
                         INTO THE FORM OF THE CERTIFICATES

       This Certificate does not represent an obligation of or interest in 
ABN AMRO Mortgage Corporation or any of its affiliates.  Neither this 
Certificate nor the underlying Loans are guaranteed by any agency or 
instrumentality of the United States.

       This certifies that the above-named Registered Owner is the registered 
owner of certain interests in a trust fund (the "Certificate Trust Fund") 
whose assets consist of, among other things, of a pool (the "Mortgage Pool") 
of conventional one- to four-family mortgage loans (the "Loans"), formed by 
ABN AMRO Mortgage Corporation (the "Depositor").  The Loans were originated 
or acquired by various financial institutions and subsequently acquired by 
the Depositor.  The Mortgage Pool was created pursuant to a Pooling and 
Servicing Agreement, dated as of the Cut-Off Date stated above (the "Pooling 
Agreement"), between the Depositor, LaSalle Home Mortgage Corporation, as 
Servicer (the "Servicer"), and Chase Bank of Texas, National Association, as 
Trustee (the "Trustee"), a summary of certain of the pertinent provisions of 
which is set forth hereafter.  To the extent not defined herein, the 
capitalized terms used herein have the meanings assigned in the Pooling 
Agreement.  Nothing  herein shall be deemed inconsistent with such meanings, 
and in the event of any conflict between the Pooling Agreement and the terms 
of this Certificate, the Pooling Agreement shall control.  This Certificate 
is issued under and is subject to the terms, provisions and conditions of the 
Pooling Agreement, to which Pooling Agreement the Holder of this Certificate, 
by virtue of the acceptance hereof, assents and by which such Holder is bound.

       Distributions will be made, pursuant to the Pooling Agreement, on the 
25th day of each month or, if such 25th day is not a Business Day, the 
Business Day immediately following (the "Distribution Date"), commencing on 
the first Distribution Date specified above, to the Person in whose name this 
Certificate is registered at the close of business on the last Business Day 
of the month immediately preceding the month of such distribution (the 
"Record Date"), to the extent of such Certificateholder's Percentage Interest 
represented by this Certificate in the portion of the Certificate 
Distribution Amount for such Distribution Date then distributable on the 
Certificates of this Class, as specified in Section 4.1 of the Pooling 
Agreement.

       Distributions on this Certificate will be made by the Trustee or its 
Paying Agent by wire transfer or by other means of payment acceptable to each 
Certificateholder of record on the immediately preceding Record Date. 
Notwithstanding the above, the final distribution on this Certificate will be 
made after due notice by the Trustee or its Paying Agent of the pendency of 
such distribution and only upon presentation and surrender of this 
Certificate to the Certificate Registrar.

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

                         ABN AMRO MORTGAGE CORPORATION
                       MORTGAGE PASS-THROUGH CERTIFICATE


       This Certificate is one of a duly authorized issue of Certificates 
designated as Mortgage Pass-Through Certificates of the Series and Class 
specified hereon (herein called the "Certificates") and  representing certain 
interests in the Certificate Trust Fund.

       The Certificates do not represent an obligation of, or an interest in, 
the Depositor or any of its affiliates and are not insured or guaranteed by 
any governmental agency.  The Certificates are limited in right of payment to 
certain collections and recoveries respecting the Loans, all as more 
specifically set forth herein and in the Pooling Agreement.  To the extent 
described in the Pooling Agreement, the Servicer is obligated to advance its 
own funds to cover certain shortfalls with respect to payments on the Loans.  
In the event Servicer funds are advanced with respect to any Loan, such 
advance is reimbursable to the Servicer from the related recoveries on such 
Loan or from other cash deposited in the Custodial Account for P & I to the 
extent that such advance is not otherwise recoverable.

       As provided in the Pooling Agreement, withdrawals from the Custodial 
Account for P&I may be made by the Servicer from time to time for purposes 
other than distributions to Certificateholders, such purposes including 
reimbursement to the Servicer of advances made, or certain expenses incurred, 
by it.

       The Pooling Agreement permits, with certain exceptions therein 
provided, the amendment thereof and the modification of the rights and 
obligations of the Depositor and the Servicer, and the rights of the 
Certificateholders under the Pooling Agreement at any time by the Depositor 
and the Trustee, with the consent of the Holders of the Certificates 
aggregating not less than 66-2/3% of the aggregate Percentage Interest 
evidenced by all of the Certificates of the Trust Fund.  For the purposes of 
such provision and except as provided below, voting rights related to 100% of 
the Aggregate Certificate Principal Balance of any Class will be allocated 
pro rata (by Certificate Principal Balance) among the Certificates of such 
Class.  Any such consent by the Holder of this Certificate shall be 
conclusive and binding on such Holder and upon all future Holders of this 
Certificate and of any Certificate issued upon the transfer hereof or in 
exchange hereof or in lieu hereof whether or not notation of such consent is 
made upon this Certificate.  The Pooling Agreement also permits the amendment 
thereof, in certain limited circumstances, without the consent of the Holders 
of any of the Certificates.  

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

       No transfer of a Certificate will be made unless such transfer is 
exempt from or is made in accordance with the registration requirements of 
the Securities Act of 1933, as amended (the "Securities Act") and any 
applicable state securities laws.  No transfer, sale, pledge or other 
disposition of a Junior Subordinate Certificate shall be made unless such 
transfer, sale, pledge or other disposition is made in accordance with 
Section 5.1(e) or Section 5.1(f) of the Pooling Agreement. Each Person who, 
at any time, acquires any ownership interest in any Junior Subordinate 
Certificate shall be deemed by the acceptance or acquisition of such 
ownership interest to have agreed to be bound by the provisions of such 
Section 5.1(e) and Section 5.1(f), as applicable.  No transfer of a Junior 
Subordinate Certificate shall be deemed to be made in accordance with such 
Section 5.1(e) unless such transfer is made pursuant to an effective 
registration statement under the Securities Act or unless the Trustee and the 
Certificate Registrar are provided with the certificates and an Opinion of 
Counsel, if required, on which the Trustee and the Certificate Registrar may 
conclusively rely, which establishes or establish to the Trustee's and the 
Certificate Registrar's satisfaction that such transfer is exempt from the 
registration requirements under the Securities Act, as follows:  In the event 
that a transfer is to be made in reliance upon an exemption from the 
Securities Act, the Trustee and the Certificate Registrar shall require, in 
order to assure compliance with the Securities Act, that the 
Certificateholder desiring to effect such transfer certify to the Trustee and 
the Certificate Registrar in writing, in substantially the form attached as 
Exhibit F to the Pooling Agreement, the facts surrounding the transfer, with 
such modifications to such Exhibit F as may be appropriate to reflect the 
actual facts of the proposed transfer, and that the Certificateholder's 
proposed transferee certify to the Trustee and the Certificate Registrar in 
writing, in substantially the form attached as Exhibit G to the Pooling 
Agreement, the facts surrounding the transfer, with such modifications to 
such Exhibit G as may be appropriate to reflect the actual facts of the 
proposed transfer.  If such certificate of the proposed transferee does not 
contain substantially the substance of Exhibit G, the Trustee and the 
Certificate Registrar shall require an Opinion of Counsel satisfactory to it 
that such transfer may be made without registration, which Opinion of Counsel 
shall not be obtained at the expense of the Trustee,  the Certificate 
Registrar, the Trust Fund or the Depositor.

       Transfers of the Junior Subordinate Certificates may also be made in 
accordance with Section 5.1(f) of the Pooling Agreement.  To effectuate a 
Certificate transfer in accordance with such Section 5.1(f), the proposed 
transferee of such Certificate must provide the Trustee, the Certificate 
Registrar and the Depositor with an investment letter substantially in the 
form of Exhibit L attached to the Pooling Agreement, which investment letter 
shall not be an expense of the Trustee, the Certificate Registrar or the 
Depositor, and which investment letter states that, among other things, such 
transferee (i) is a "qualified institutional buyer" as defined under Rule 
144A, acting for its own account or the accounts of other "qualified 
institutional buyers" as defined under Rule 144A, and (ii) is aware that the 
proposed transferor intends to rely on the exemption from registration 
requirements under the Securities Act provided by Rule 144A.  Notwithstanding 
the foregoing, the proposed transferee of such Certificate shall not be 
required to provide the Trustee, the Certificate Registrar or the Depositor 
with Annex 1 or Annex 2 to the form of such Exhibit L if the Depositor so 
consents prior to each such transfer.  Such transfers shall be deemed to have 
complied with the requirements of Section 5.1(f) of the Pooling Agreement. 
The Holder of a Certificate desiring to effect such transfer does hereby 
agree to indemnify the Trustee, and the Certificate Registrar, the Depositor, 
and the Certificate Registrar against any liability that may result if 
transfer is not made in accordance with the Pooling Agreement.

       The Certificates are issuable only as registered Certificates without 
coupons in Authorized Denominations specified in the Pooling Agreement.  As 
provided in the Pooling Agreement and subject to certain limitations therein 
set forth, Certificates are exchangeable for new Certificates of Authorized 
Denominations evidencing the same aggregate interest in the portion of the 
Available Distribution Amount distributable on this Class of Certificate, as 
requested by the Holder surrendering the same.

       A reasonable service charge may be made for any such registration of 
transfer or exchange, and the Trustee or the Certificate Registrar may 
require payment of a sum sufficient to cover any tax or other governmental 
charge payable in connection therewith.

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

       The respective obligations and responsibilities of the Servicer and 
the Trustee created under the Pooling Agreement (other than the obligation to 
make payments to Certificateholders as set forth therein) shall terminate 
upon the earlier of (i) the later of the final payment or other liquidation 
(or any Advance with respect thereto) of the last Loan remaining in the Trust 
Fund and the disposition of all property acquired in respect of any Loan or

agrees that, in connection with any purchase of securities sold to the Buyer

securities for a third party unless the Buyer has obtained a current 
representation letter from such third party or taken other appropriate steps 
contemplated by Rule 144A to conclude that such third party independently 
meets the definition of "qualified institutional buyer" set forth in Rule 
144A.

certification is made of any changes in the information and conclusions

                         SPECIAL SERVICING PROCEDURES

              Section 2.01.  REPORTS AND NOTICES.

                     (a)    In connection with the performance of its duties 
under the Pooling and Servicing Agreement relating to the realization upon 
defaulted Loans, the Depositor, as Servicer, shall provide to the Purchaser 
the following notices and reports:

                     (b)    Within five Business Days after each Distribution 
Date (or included in or with the monthly statement to Certificateholders 
pursuant to the Pooling and Servicing Agreement), the Depositor shall provide 
to the Purchaser a report indicating for the Trust the number of Loans that 
are (A) thirty days, (B) sixty days, (C) ninety days or more delinquent or 
(D) in foreclosure, and indicating for each such Loan the outstanding 
principal balance.

                     (c)    Prior to the Commencement of Foreclosure in 
connection with any Loan, the Depositor shall provide the Purchaser with a 
notice (sent by telecopier) of such proposed and imminent foreclosure, 
stating the loan number and the aggregate amount owing under the Loan.

                     (d)    If requested by the Purchaser, the Depositor 
shall make its servicing personnel available (during their normal business 
hours) to respond to reasonable inquiries by the Purchaser in connection with 
any Loan identified in a report under subsection (a)(i)(B), (a)(i)(C), 
(a)(i)(D) or (a)(ii) which has been given to the Purchaser; provided, that 
(1) the Depositor shall only be required to provide information that is 
readily accessible to its servicing personnel and is non-confidential and (2) 
the Depositor shall not be required to provide any written information under 
this subsection.

                     (e)    In addition to the foregoing, the Depositor shall 
provide to the Purchaser such information as the Purchaser may reasonably 
request concerning each Loan that is at least sixty days delinquent and each 
Loan which has become real estate owned, through the final liquidation 
thereof; provided that the Depositor shall only be required to provide 
information that is readily accessible to its servicing personnel and is 
non-confidential.

                     (f)    With respect to all Loans which are serviced at 
any time by the Depositor through a Subservicer, the Depositor shall be 
entitled to rely for all purposes hereunder, including for purposes of 
fulfilling its reporting obligations under this Section 2.01 on the accuracy 
and completeness of any information provided to it by the applicable 
Subservicer.

              Section 2.02.  PURCHASER'S ELECTION TO DELAY FORECLOSURE 
PROCEEDINGS.

                     (a)    The Purchaser directs the Depositor that in the 
event that the Depositor does not receive written notice of the Purchaser's 
election pursuant to subsection (b) below within 24 hours (exclusive of any 
intervening non-Business Days) of transmission of the notice provided by the 
Depositor under Section 2.01(a)(ii), subject to extension as set forth in 
Section 2.02(b), the Depositor shall proceed with the Commencement of 
Foreclosure in respect of such Loan in accordance with its normal foreclosure 
policies without further notice to the Purchaser.  Any foreclosure that has 
been initiated may be discontinued (i) without notice to the Purchaser, if 
the Loan has been brought current or if a refinancing or prepayment occurs 
with respect to the Loan (including by means of a short payoff approved by 
the Depositor) (ii) with notice to the Purchaser if the Depositor has reached 
the terms of a forbearance agreement with the borrower.  In such latter case 
the Depositor may complete such forbearance agreement unless instructed 
otherwise by the Purchaser within one Business Day of notification.

                     (b)    In connection with any Loan with respect to which 
a notice under Section 2.01(a)(ii) has been given to the Purchaser, the 
Purchaser may elect, for reasonable cause as determined by the Purchaser, to 
instruct the Depositor to delay the Commencement of Foreclosure until such 
term as the Purchaser determines that the Depositor may proceed with the 
Commencement of Foreclosure.  Such election must be evidenced by written 
notice received within 24 hours (exclusive of any intervening non-Business 
Days) of transmission of the notice provided by the Depositor under Section 
2.01(a)(ii).  Such 24 hour period shall be extended for no longer than an 
additional four Business Days after the receipt of the information if the 
Purchaser requests additional information related to such foreclosure; 
provided, however that the Purchaser will have at least one Business Day to 
respond to any requested additional information.  Any such additional 
information shall (i) not be confidential in nature and (ii) be obtainable by 
the Depositor from existing reports, certificates or statements or otherwise 
be readily accessible to its servicing personnel.  The Purchaser agrees that 
it has no right to deal with the mortgagor.  If the Depositor's normal 
foreclosure policy includes acceptance of a deed-in-lieu of foreclosure or 
short payoff, the Purchaser will be notified and given one Business Day to 
respond.

                     (c)    With respect to any Loan as to which the 
Purchaser has made an Election to Delay Foreclosure, the Purchaser shall 
obtain a Current Appraisal as soon as practicable, and shall provide the 
Depositor with a copy of such Current Appraisal.

                     (d)    Within two Business Days of making any Election 
to Delay Foreclosure, the Purchaser shall remit by wire transfer to the 
Depositor, for deposit in the Collateral Fund, an amount, as calculated by 
the Depositor, equal to the sum of (i) 125% of the greater of the outstanding 
Principal Balance of the Loan and the value shown in the Current Appraisal 
referred to in subsection (c) above (or, if such Current Appraisal has not 
yet been obtained, the Depositor's estimate thereof, in which case the 
required deposit under this subsection shall be adjusted upon obtaining of 
such Current Appraisal), and (ii) three months' interest on the Loan at the 
applicable Mortgage Rate.  If any Election to Delay Foreclosure extends for a 
period in excess of three months (such excess period being referred to herein 
as the "Excess Period"), the Purchaser shall remit by wire transfer in 
advance to the Depositor for deposit in the Collateral Fund the amount, as 
calculated by the Depositor, equal to interest on the Loan at the applicable 
Mortgage Rate for the Excess Period.  The terms of this Agreement shall no 
longer apply to the servicing of any Loan upon the failure of the Purchaser 
to deposit the above amounts relating to the Loan within two Business Days of 
the Election to Delay Foreclosure.

                     (e)    With respect to any Loan as to which the 
Purchaser has made an Election to Delay Foreclosure, the Depositor may 
withdraw from the Collateral Fund from time to time amounts necessary to 
reimburse the Depositor for all Advances and Liquidation Expenses thereafter 
made by the Depositor as Servicer in accordance with the Pooling and 
Servicing Agreement.  To the extent that the amount of any such Liquidation 
Expense is determined by the Depositor based on estimated costs, and the 
actual costs are subsequently determined to be higher, the Depositor may 
withdraw the additional amount from the Collateral Fund.  In the event that 
the Loan is brought current by the Mortgagor and the foreclosure action is 
discontinued, the amounts so withdrawn from the Collateral Fund shall be 
redeposited therein as and to the extent that reimbursement therefor from 
amounts paid by the Mortgagor is not prohibited pursuant to the Pooling and 
Servicing Agreement.  Except as provided in the preceding sentence, amounts 
withdrawn from the Collateral Fund to cover Advances and Liquidation Expenses 
shall not be redeposited therein or otherwise reimbursed to the Purchaser.  
If and when any such Loan is brought current by the Mortgagor, all amounts 
remaining in the Collateral Fund in respect of such (after adjustment for all 
withdrawals and deposits pursuant to this subsection) shall be released to 
the Purchaser.

<PAGE>

                     (f)    With respect to any Loan as to which the 
Purchaser has made an Election to Delay Foreclosure, the Depositor shall 
continue to service the Loan in accordance with its customary procedures 
(other than the delay in Commencement of Foreclosure as provided herein).  If 
and when the Purchaser shall notify the Depositor that it believes that it is 
appropriate to do so, the Depositor shall proceed with the Commencement of 
Foreclosure.  In any event, if the Loan is not brought current by the 
mortgagor by the time the loan becomes 6 months delinquent, the Purchaser's 
election shall no longer be effective and at the Purchaser's option, either 
(i) the Purchaser shall purchase the Loan from the Trust Fund at a purchase 
price equal to the fair market value as shown on the Current Appraisal, to be 
paid by (x) applying any balance in the Collateral Fund to such purchase 
price, and (y) to the extent of any deficiency, by wire transfer of 
immediately available funds to the Depositor or Trustee; or (ii) the 
Depositor shall proceed with the Commencement of Foreclosure.

                     (g)    Upon the occurrence of a liquidation with respect 
to any Loan as to which the Purchaser made an Election to Delay Foreclosure 
and as to which the Depositor proceeded with the Commencement of Foreclosure 
in accordance with subsection (f) above, the Depositor shall calculate the 
amount, if any, by which the value shown on the Current Appraisal obtained 
under subsection (c) exceeds the actual sales price obtained for the related 
Mortgaged Property (net of Liquidation Expenses and accrued interest related 
to the extended foreclosure period), and the Depositor shall withdraw the 
amount of such excess from the Collateral Fund, shall remit the same to the 
Trust Fund and in its capacity as Servicer shall apply such amount as 
additional Liquidation Proceeds pursuant to the Pooling and Servicing 
Agreement.  After making such withdrawal, all amounts remaining in the 
Collateral Fund in respect of such Loan (after adjustment for all withdrawals 
and deposits pursuant to subsection (e)) shall be released to the Purchaser.

              Section 2.03.  PURCHASER'S ELECTION TO COMMENCE FORECLOSURE 
PROCEEDINGS.

                     (a)    In connection with any Loan identified in a 
report under Section 2.01(a)(i)(B), the Purchaser may elect, for reasonable 
cause as determined by the Purchaser, to instruct the Depositor to proceed 
with the Commencement of Foreclosure as soon as practicable.  Such election 
must be evidenced by written notice received by the Depositor by 5:00 p.m., 
New York City time, on the third Business Day following the delivery of such 
report under Section 2.01(a)(i).

                     (b)    Within two Business Days of making any Election 
to Foreclose, the Purchaser shall remit to the Depositor, for deposit in the 
Collateral Fund, an amount, as calculated by the Depositor, equal to 125% of 
the current Principal Balance of the Loan and three months' interest on the 
Loan at the applicable Mortgage Rate.  If and when any such Loan is brought 
current by the Mortgagor, all amounts in the Collateral Fund in respect of 
such Loan shall be released to the Purchaser.  The terms of this Agreement 
shall no longer apply to the servicing of any Loan upon the failure of the 
Purchaser to deposit the above amounts relating to the Loans within two 
Business Days at the Election to Foreclose.

                     (c)    With respect to any Loan as to which the 
Purchaser has made an Election to Foreclose, the Depositor shall continue to 
service the Loan in accordance with its customary procedures (other than to 
proceed with the Commencement of Foreclosure as provided herein).  In 
connection therewith, the Depositor shall have the same rights to make 
withdrawals for Advances and Liquidation Expenses from the Collateral Fund as 
are provided under Section 2.02(e), and the Depositor shall make 
reimbursements thereto to the limited extent provided under such subsection.  
The Depositor shall not be required to proceed with the Commencement of 
Foreclosure if (i) the same is stayed as a result of the Mortgagor's 
bankruptcy or is otherwise barred by applicable law, or to the extent that 
all legal conditions precedent thereto have not yet been complied with or 
(ii) the Depositor believes there is a breach of representation or warranties 
by the Depositor, which may result in a repurchase or substitution of such 
Loan, or (iii) the Depositor reasonably believes the Mortgaged Property may 
be contaminated with or affected by hazardous wastes or hazardous substances 
(and the Depositor supplies the Purchaser with information supporting such 
belief).  The Depositor will repurchase or substitute a Loan pursuant to the 
preceding clause (ii) within the time period specified in the Pooling and 
Servicing Agreement.  Any foreclosure that has been initiated may be 
discontinued (i) without notice to the Purchaser if the Loan has been brought 
current or if a refinancing or prepayment occurs with respect to the  Loan 
(including by means of a short payoff approved by the Depositor), or (ii) 
with notice to the Purchaser if the Depositor has reached the terms of a 
forbearance agreement unless instructed otherwise by the Purchaser within two 
Business Days of notification.

                     (d)    Upon the occurrence of a liquidation with respect 
to any Loan as to which the Purchaser made an Election to Foreclose and as to 
which the Depositor proceeded with the Commencement of Foreclosure in 
accordance with subsection (c) above, the Depositor shall calculate the 
amount, if any, by which the Principal Balance of the Loan at the time of 
liquidation (plus all unreimbursed Advances and Liquidation Expenses in 
connection therewith other than those paid from the Collateral Fund) exceeds 
the actual sales price obtained for the related Mortgaged Property, and the 
Depositor shall withdraw the amount of such excess from the Collateral Fund, 
shall remit the same to the Trust Fund and in its capacity as Servicer shall 
apply such amount as additional Liquidation 


                                      R-4
<PAGE>

Proceeds pursuant to the Pooling and Servicing Agreement.  After making such 
withdrawal, all amounts remaining in the Collateral Fund (after adjustment 
for all withdrawals and deposits pursuant to subsection (c)) in respect of 
such Loan shall be released to the Purchaser.

              Section 2.04.  TERMINATION.

                     (a)    With respect to all Loans included in the Trust 
Fund, the Purchaser's rights to make any Election to Delay Foreclosure or any 
Election to Foreclose and the Depositor's obligations under Section 2.01 
shall terminate (i) at such time as the Certificate Principal Balance of the 
Certificates has been reduced to zero, (ii) if the greater of (x) 43% (or 
such lower or higher percentages that represents the Depositor's actual 
historical loss experience with respect to the Loans in the related pool) of 
the aggregate principal balance of all Loans that are in foreclosure or are 
more than 90 days delinquent on a contractual basis and REO properties or if 
the aggregate amount that the Depositor estimates will be required to be 
withdrawn from the Collateral Fund with respect to Loans as to which the 
Purchaser has made an Election to Delay Foreclosure or an Election to 
Foreclose exceeds (z) the Outstanding Certificate Principal Balance of the 
Certificates, or (iii) upon any transfer by the Purchaser of any interest 
(other than the minority interest therein, but only if the transferee 
provides written acknowledgment to the Depositor of the Purchaser's right 
hereunder and that such transferee will have no rights hereunder) in the 
Certificates (whether or not such transfer is registered under the Pooling 
and Servicing Agreement), including any such transfer in connection with a 
termination of the Trust Fund.  Except as set forth above, this Agreement and 
the respective rights, obligations and responsibilities of the Purchaser and 
the Depositor hereunder shall terminate upon the later to occur of (i) the 
final liquidation of the last Loan as to which the Purchaser made any 
Election to Delay Foreclosure or any Election to Foreclose and the withdrawal 
of all remaining amounts in the Collateral Fund as provided herein and (ii) 
ten (10) Business Day's notice.

                     (b)    Purchaser's rights pursuant to Section 2.02 or 
2.03 of this Agreement shall terminate with respect to a Loan as to which the 
Purchaser has exercised its rights under Section 2.02 or 2.03 hereof, upon 
Purchaser's failure to deposit any amounts required pursuant to Section 
2.02(d) or 2.03(b).

                     (c)    Neither the Servicer nor any of its directors, 
officers, employees or agents shall be under any liability 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 Servicer or any such Person against any 
liability which would otherwise be imposed by reason of willful misfeasance, 
bad faith or gross negligence in the performance of duties or by reason of 
reckless disregard of obligations and duties hereunder.  The Servicer and any 
director, officer, employee or agent thereof may rely in good faith on any 
document of any kind prima facie properly executed and submitted by an Person 
respecting any matters arising hereunder.


                                 ARTICLE III.
                                       
                      COLLATERAL FUND; SECURITY INTEREST

              Section 3.01.  COLLATERAL FUND.

              Upon receipt from the Purchaser of the initial amount required 
to be deposited in the Collateral Fund pursuant to Article 11, the Depositor 
shall establish and maintain with itself as a segregated account on its books 
and records an account (the "Collateral Fund"), entitled "LaSalle Home 
Mortgage Corporation, as Servicer, for the benefit of registered holders of 
ABN AMRO Mortgage Corporation Multi-Class Mortgage Pass-Through Certificates, 
Series 1998-3." Amounts in the Collateral Fund shall continue to be the 
property of the Purchaser, subject to the first priority security interest 
granted hereunder for the benefit of the Certificateholders, until withdrawn 
from the Collateral Fund pursuant to Section 2.02 or 2.03 hereof.

              Upon the termination of this Agreement and the liquidation of 
all Loans as to which the Purchaser has made any Election to Delay 
Foreclosure or any Election to Foreclose pursuant to Section 2.04 hereof, the 
Depositor shall distribute to the Purchaser all amounts remaining in the 
Collateral Fund together with any investment earnings thereon.

              In no event shall the Purchaser (i) take or cause the Trustee 
or the Depositor to take any action that could cause any REMIC established 
under the Trust Agreement to fail to qualify as a REMIC or cause the 
imposition on any such REMIC of any "prohibited transaction" or "prohibited 
contribution" taxes or (ii) cause the Trustee or the Depositor to fail to 
take any action necessary to maintain the status of any such REMIC as a REMIC.

              Section 3.02.  COLLATERAL FUND PERMITTED INVESTMENTS.

              The Depositor shall, at the written direction of the Purchaser 
invest the funds in the Collateral Fund in Collateral Fund Permitted 
Investments.  Such direction shall not be changed more frequently than 
quarterly.  In the absence of any direction, the Depositor shall select such 
investments in accordance with the definition of Collateral Fund Permitted 
Investments in its discretion.

              All income and gain realized from any investment as well as any 
interest earned on deposits in the Collateral Fund (net of any losses on such 
investments) and any payments of principal made in respect of any Collateral 
Fund Permitted Investment shall be deposited in the Collateral Fund upon 
receipt.  All costs and realized losses associated with the purchase and sale 
of Collateral Fund Permitted Investments shall be borne by the Purchaser and 
the amount of net realized losses shall be deposited by the Purchaser in the 
Collateral Fund.  The Depositor shall periodically (but not more frequently 
than monthly) distribute to the Purchaser upon request an amount of cash, to 
the extent cash is available therefor in the Collateral Fund, equal to the 
amount by which the balance of the Collateral Fund, after giving effect to 
all other distributions to be made from the Collateral Fund on such date, 
exceeds the Required Collateral Fund Balance.  Any amounts so distributed 
shall be released from the lien and security interest of this Agreement.

              Section 3.03.  GRANT OF SECURITY INTEREST.

              The Purchaser grants to the Depositor and the Trustee for the 
benefit of the Certificateholders a security interest in and lien on all of 
the Purchaser's right, title and interest, whether now owned or hereafter 
acquired, in and to:  (1) the Collateral Fund, (2) all amounts deposited in 
the Collateral Fund and Collateral Fund Permitted Investments in which such 
amounts are invested (and the distributions and proceeds of such investments) 
and (3) all cash and non-cash proceeds of any of the foregoing, including 
proceeds of the voluntary or involuntary conversion thereof (all of the 
foregoing collectively, the "Collateral").

              The Purchaser acknowledges the lien on and security interest in 
the Collateral for the benefit of the Certificateholders.  The Purchaser 
shall take all actions requested by the Depositor or the Trustee as may be 
reasonably necessary to perfect the security interest created under this 
Agreement in the Collateral and cause it to be prior to all other security 
interests and liens, including the execution and delivery to the Depositor 
for filing of appropriate financing statements in accordance with applicable 
law.  The Depositor shall file appropriate continuation statements, or 
appoint an agent on its behalf to file such statements, in accordance with 
applicable law.

              Section 3.04.  COLLATERAL SHORTFALLS.

              In the event that amounts on deposit in the Collateral Fund at 
any time are insufficient to cover any withdrawals therefrom that the 
Depositor or the Trustee is then entitled to make hereunder, the Purchaser 
shall be obligated to pay such amounts to the Depositor or the Trustee 
immediately upon demand. Such obligation shall constitute a general corporate 
obligation of the Purchaser.

                                  ARTICLE IV.

                            MISCELLANEOUS PROVISIONS

              This Agreement may be amended from time to time by the 
Depositor and the Purchaser by written agreement signed by the Depositor and 
the Purchaser.

              Section 4.02.  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 4.03.  GOVERNING LAW.

              This Agreement shall be construed in accordance with the laws 
of the State of New York and the obligations, rights and remedies of the

                           MORTGAGE LOAN PURCHASE AGREEMENT


          Mortgage Loan Purchase Agreement (the "AGREEMENT"), dated as of 
October 27, 1998, between Standard Federal Bank (the "SELLER") and ABN AMRO 
Mortgage Corporation (the "PURCHASER").

          Subject to the terms and conditions of this Agreement, the Seller 
agrees to sell and the Purchaser agrees to purchase certain mortgage loans 
(the "MORTGAGE LOANS") as described herein and as identified on the Mortgage 
Loan Schedule defined in SECTION 2 hereof.  The Mortgage Loans will be 
purchased on a servicing retained basis.

          Now, therefore, in consideration of the premises and the mutual 
agreements set forth herein, the parties agree as follows:

     SECTION 1.    PURCHASE AND SALE OF THE MORTGAGE LOANS.

     (a)  Pursuant to the terms hereof and upon satisfaction of the 
conditions set forth herein, the Seller agrees to sell and the Purchaser 
agrees to purchase, Mortgage Loans having the general characteristics set 
forth in this Agreement and specifically identified on the Mortgage Loan 
Schedule, for the Purchase Price set forth below in SECTION 3(a) hereof and 
having an aggregate principal balance on and as of the date of such Mortgage 
Loan Schedule (the "CUT-OFF DATE") of approximately $360,000,000 after 
deduction of principal payments due on or before the Cut-Off Date (which 
amount may vary plus or minus 5% thereof), or such other aggregate principal 
balance as agreed by the Purchaser and the Seller as evidenced by the actual 
aggregate principal balance of the Mortgage Loans accepted by the Purchaser 
on the Closing Date (as defined below).

     (b)  Subject to mutual agreement between the Purchaser and the Seller, 
the closing for the purchase and sale of the Mortgage Loans shall take place 
on October 27, 1998 (the "Closing Date") at the office of Purchaser's counsel 
in Chicago, Illinois or such other place as the parties shall agree.

     SECTION 2.    MORTGAGE LOAN SCHEDULE.  Attached to this Agreement as 
Schedule 1 is a listing of the Mortgage Loans evidenced by promissory notes, 
mortgage notes or other evidence of indebtedness (the "MORTGAGE NOTES") 
evidencing the indebtedness of an obligor (the "MORTGAGOR") under the 
mortgages, deeds of trust or other instruments securing a Mortgage Loan (the 
"MORTGAGES") to be purchased by and delivered to the Purchaser on the Closing 
Date (as such may be amended prior to the Closing Date by mutual agreement of 
the parties) (the "MORTGAGE LOAN SCHEDULE").  The "Mortgage Loan Schedule" as 
of the Closing Date shall refer to the Mortgage Loan Schedule as delivered on 
the Cut-off Date related to such Mortgage Loans to be purchased by or on 
behalf of the Purchaser pursuant to the terms of this Agreement.  The 

<PAGE>

Mortgage Loan Schedule shall contain as to each Mortgage Loan listed thereon, 
at a minimum, the Mortgage Loan information indicated on SCHEDULE 2 hereto.

     SECTION 3.    PURCHASE PRICE.

     (a)  In exchange for the Mortgage Loans, on the Closing Date, the 
Purchaser shall transfer to the Seller by wire transfer in immediately 
available funds the purchase price (the "PURCHASE PRICE") which is equal to 
the principal balance thereof as of the Cut-Off Date plus any accrued and 
unpaid interest thereon to such Cut-Off Date.

     (b)  The Purchaser shall be entitled to all scheduled payments of 
principal and interest due with respect to the Mortgage Loans after the 
Cut-Off Date, and all other recoveries of principal and interest collected 
after the Cut-Off Date (other than in respect of principal and interest on 
the Mortgage Loans due on or before the Cut-Off Date).  The Seller shall be 
entitled to all scheduled payments of principal and interest due with respect 
to the Mortgage Loans on or before the Cut-Off Date, and all other recoveries 
of principal and interest collected on or before the Cut-Off Date (other than 
in respect of principal and interest on the Mortgage Loans due after the 
Cut-Off Date).  The Principal Balance of each Mortgage Loan as of the Cut-Off 
Date is determined after deduction of payments of principal due on or before 
the Cut-Off Date whether or not collected.  Therefore, payments of scheduled 
principal and interest prepaid for a date due following the Cut-Off Date 
shall not be deducted from the Principal Balance as of the Cut-Off Date but 
such prepaid amounts shall belong to and be promptly remitted to the 
Purchaser.  

     SECTION 4.    EXAMINATION OF MORTGAGE FILES.

     Prior to the Closing Date, the Seller will have made files for each 
Mortgage Loan, that consist at least of the documents listed on SCHEDULE 3 
attached hereto (with respect to each Mortgage Loan, a "Mortgage File", and 
collectively, the "MORTGAGE FILES"), available to the Purchaser or its 
agents, for examination at the Seller's offices or such other location as 
shall otherwise be agreed upon by the Purchaser and the Seller.  The 
Purchaser may purchase all or part of the Mortgage Loans with or without 
conducting any partial or complete examination.  The fact that the Purchaser 
or its agents have conducted or have failed to conduct any partial or 
complete examination of the Mortgage Files shall not affect the Purchaser's 
rights under this Agreement, including, but not limited to, the rights to 
demand repurchase, substitution or other relief as provided in this Agreement.

     SECTION 5.    TRANSFER OF MORTGAGE LOANS; POSSESSION OF MORTGAGE FILES.

     (a)  On the Closing Date, subject to the satisfaction of the terms and 
conditions hereof the Seller shall sell, transfer, assign, set over and 
otherwise convey to the Purchaser, without recourse, but subject to the terms 
of this Agreement, all right, title and interest of the Seller in and to the 
Mortgage Loans and all proceeds thereof, wherever located, including without 
limitation, all amounts in respect of principal and interest received or 
receivable with respect to Mortgage Loan payments due after the Cut-Off Date 
(and including scheduled payments of 

                                       -2-
<PAGE>

principal and interest due after the Cut-Off Date but received by the Seller 
on or before the Cut-Off Date, but not including payments of principal and 
interest due on the Mortgage Loans on or before the Cut-Off Date), together 
with the proceeds of any related mortgage insurance policies.  Such transfer 
shall be made directly to the Purchaser in accordance with the letter 
delivered to the Seller by the Purchaser attached hereto as EXHIBIT A (the 
"INSTRUCTION LETTER").  The Seller's records will accurately reflect the sale 
of each Mortgage Loan to the Purchaser.

     (b)  The ownership of each Mortgage Loan and the related Mortgage Note, 
the Mortgage and the contents of the related Mortgage File shall be, upon 
satisfaction of SUBSECTION 5(a) hereof, vested in the Purchaser and the 
ownership of all records and documents with respect to such Mortgage Loan 
prepared by or which come into the possession of the Seller shall immediately 
vest in the Purchaser and shall be retained and maintained by the Seller at 
the will and for the benefit of the Purchaser in a custodial capacity only.  
The Seller shall deliver to the Purchaser or its agent in accordance with the 
instructions set forth in EXHIBIT A, simultaneously with the execution and 
delivery of this Agreement or prior to the Closing Date, all of the documents 
pertaining to each Mortgage Loan.

     (c)  The transfer of the Mortgage Loans as described herein shall be 
absolute and is intended by the parties to be a sale.  In the event that a 
court deems the conveyance set forth herein not to constitute a sale, the 
Seller shall have granted to the Purchaser and the Trustee a first priority 
security interest in the Mortgage Loans and in the proceeds thereof of any 
kind or nature whatsoever, and in the proceeds of any related insurance 
policies, subject to the satisfaction or waiver of the conditions set forth 
in SECTION 11 hereof, and shall take, or shall cause to have been taken, all 
steps necessary prior to the Closing Date to perfect such security interest 
in the Purchaser.

     SECTION 6.    BOOKS AND RECORDS.  

     On the Closing Date, following the sale of the Mortgage Loans to the 
Purchaser, title to each Mortgage and the related Mortgage Note shall be 
transferred to the Purchaser or its assignee in accordance with this 
Agreement. All rights arising out of the Mortgage Loans after the Cut-Off 
Date including, but not limited to, any and all funds received on or in 
connection with a Mortgage Loan and due after the Cut-Off Date shall be 
received and held by the Seller in a custodial capacity for the benefit of 
the Purchaser or its assignee as the owner of the Mortgage Loans in 
accordance herewith and shall be delivered or caused to be delivered by the 
Seller to the Purchaser or its assignee on or immediately following the 
Closing Date.  Any funds received by the Seller, the Purchaser or LaSalle 
Home Mortgage Corporation after the Cut-Off Date but due prior to the Cut-Off 
Date shall remain the property of the Seller and shall be promptly remitted 
to the Seller.

agrees to take or cause to be taken such further actions to execute, deliver 
and file or cause to be executed, delivered and filed, such further documents 
and instruments (including, without limitation, any UCC financing statements) 
as may be necessary, or as the Purchaser may reasonably request, in order to 
perfect and maintain the security interest created pursuant to said section 
and to otherwise fully effectuate the purposes, terms and conditions of this 
Agreement, and the Purchaser shall cooperate in any such action.  

     (b)  The Seller shall: (i) promptly execute, deliver, and file any 
financing statements, amendments, continuation statements, assignments, 
certificates and other documents with respect to such security interest as 
may be necessary to enable the Purchaser to perfect or to maintain the 
perfection of such security interest, each in form and substance satisfactory 
to the Purchaser; and the Seller hereby grants to the Purchaser, subject to 
the satisfaction or waiver of the conditions set forth in SECTION 11 hereof, 
the right, at the Purchaser's option, to file any or all such financing 
statements, amendments, continuation statements, assignments, certificates 
and other documents pursuant to the UCC and otherwise without its signature 
and hereby irrevocably appoints the Purchaser, subject to the satisfaction or 
waiver of the conditions set forth in SECTION 11 hereof, as its 
attorney-in-fact to execute, deliver and file any such financing statements, 
amendments, continuation statements, assignments, certificates and other 
documents in the Seller's name and to perform all other acts which the 
Purchaser deems appropriate to perfect or to maintain the perfection of the 
security interest; and (ii) notify the Purchaser within five (5) days after 
the occurrence of any of the following: (A) any change in the Seller's 
corporate name or any trade name; (B) any change in the Seller's location of 
its chief executive office or principal place of business; and (C) any merger 
or consolidation or other change in Seller's identity or material change in 
its corporate structure.

     SECTION 8.    REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF SELLER.

     (a)  The Seller hereby represents and warrants to the Purchaser as of the
Closing Date (or such other date as is specified in the related representation
or warranty) as follows:

          matters to which like properties are commonly subject which do not
          individually, or in the aggregate, materially interfere with the 
          benefits of the security intended to be provided by the Mortgage;

          to FNMA or FHLMC;

                    (m)  no foreclosure action is threatened or has been
          commenced (except for the filing of any notice of default) with
          respect to the Mortgage Loan; and except for payment delinquencies not
          in excess of 30 days, to the best of the Seller's knowledge, there is
          no default, breach, violation or event of acceleration existing under
          the Mortgage or the related Mortgage Note and no event which, with the
          passage of time or with notice and the expiration of any grace or cure
          period, would constitute a default, breach, violation or event of
          acceleration; and the Seller has not waived any default, breach,
          violation or event of acceleration;

                    (n)  Each Mortgage Loan was originated on FNMA or FHLMC

          the time of origination or assumption of the applicable Mortgage Loan,

                    (p)  that an appraisal of each Mortgaged Property was
          conducted at the time of origination of the related Mortgage Loan, and
          that each such appraisal was conducted in accordance with FNMA or
          FHLMC criteria, on FNMA or FHLMC forms and comparables on at least
          three properties were obtained;

                                       -7-
<PAGE>

                    (q)  that no Mortgage Loan had a Loan-to-Value Ratio at
          origination in excess of 95%;

                    (r)  the Mortgage Loans were not selected in a manner to
          adversely affect the interests of the Purchaser and the Seller knows
          of no conditions which reasonably would cause it to expect any
          Mortgage Loan to become delinquent or otherwise lose value;

                    (s)  each Mortgage Loan was either (A) originated directly
          by or closed in the name of either: (i) a savings and loan
          association, savings bank, commercial bank, credit union, insurance
          company, or similar institution which is supervised and examined by a
          federal or state authority or (ii) a mortgagee approved by the
          Secretary of Housing and Urban Development pursuant to Sections 203
          and 211 of the National Housing Act or (B) originated or underwritten
          by an entity employing underwriting standards consistent with the
          underwriting standards of an institution as described in subclause
          (A)(i) or (A)(ii) above; and

                    (t)  each Mortgage Loan is a "qualified mortgage" within the
          meaning of Section 860G of the Internal Revenue Code of 1986.

          It is understood and agreed that the representations and
     warranties set forth in this SECTION 8 shall survive the sale of the
     Mortgage Loans to the Purchaser and shall inure to the benefit of the
     Purchaser, notwithstanding any restrictive or qualified endorsement on
     any Mortgage Note or assignment of Mortgage or the examination of any
     Mortgage File.

          Upon discovery by either the Seller, the Purchaser or its
     designees of a breach of any of the foregoing representations or
     warranties of the Seller which materially and adversely affects (1)
     the value of any of the Mortgage Loans actually delivered or (2) the
     interests of the Purchaser therein, the party discovering such breach
     shall give prompt written notice to the other.  Within 90 (ninety)
     days of its discovery or its receipt of notice of any such breach of a
     representation or warranty, the Seller shall, with respect to the
     Mortgage Loan(s) to which such breach relates, (i) cure such breach in
     all material respects (except for a breach of that portion of the
     representation and warranty relating to any casualty from the presence
     of hazardous waste or hazardous substances), (ii) repurchase such
     Mortgage Loan or Mortgage Loans (or any property acquired in respect
     thereof) from the Purchaser at the Purchase Price, as adjusted for the
     then current principal balance or (iii) within the 90 (ninety)-day
     period following the Closing Date substitute another mortgage loan for
     such Mortgage Loan.  Such substitute mortgage loan shall on the date
     of substitution, (i) have a principal balance not in excess of the
     principal balance of the defective Mortgage Loan,

                                       -8-
<PAGE>

     (ii) be accruing interest at a rate of interest at least equal to that of
     the defected Mortgage Loan, (iii) have a remaining term to stated maturity
     not greater than, and not more than two years less than, that of the
     Mortgage Loan so substituted, (iv) have an original loan-to-value ratio not
     higher than that of the Mortgage Loan so substituted and a current loan-to-
     value ratio not higher than that of the Mortgage Loan so substituted, and
     (v) comply with all the representations and warranties relating to Mortgage
     Loans set forth herein, as of the date of substitution (such mortgage loan
     being referred to herein as a "QUALIFYING SUBSTITUTE MORTGAGE LOAN").
     Except as set forth in SECTION 13 hereof, it is understood and agreed that
     the obligations of the Seller set forth in this SECTION 8 to cure,
     substitute for or repurchase a defective Mortgage Loan constitute the sole
     remedies of the Purchaser respecting a breach of the foregoing
     representations and warranties.

          The Purchaser, upon receipt by it of the full amount of the
     Purchase Price as adjusted for the then current principal balance for
     a Mortgage Loan that is repurchased, or upon receipt of the Mortgage
     File for a Qualifying Substitute Mortgage Loan for a Mortgage Loan
     that is substituted or repurchased, shall release or cause to be
     released and reassign to the Seller the related Mortgage File for the
     Mortgage Loan that is substituted and shall execute and deliver such
     instruments of transfer or assignment, in each case without recourse,
     representation, or warranty, as shall be necessary to vest in the
     Seller or its designee or assignee title to any such substituted
     Mortgage Loan released pursuant hereto, free and clear of all security
     interests, liens and other encumbrances created by this Agreement,
     which instruments shall be prepared by the Seller at its expense and
     shall be reasonably acceptable to the Purchaser, and the Purchaser
     shall have no further responsibility with respect to the Mortgage File
     relating to such Mortgage Loan that is substituted.

          Any cause of action against the Seller or relating to or arising
     out of the breach of any representations and warranties made in this
     SECTION 8 shall accrue as to any Mortgage Loan upon (i) discovery of
     such breach by the Purchaser or notice thereof by the Seller to the
     Purchaser, (ii) failure by the Seller to cure such breach, repurchase
     such Mortgage Loan or substitute a Qualifying Substitute Mortgage Loan
     as specified above, and (iii) demand upon the Seller by the Purchaser
     for all amounts payable in respect of such Mortgage Loan.

     SECTION 9.    REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF PURCHASER.

     of whether such enforcement is considered in a proceeding in equity or at
     law;

liabilities (or actions in respect thereof) arise out of or are based upon any
representation or warranty made by the Seller in Section 8 hereof on which
Purchaser has relied, being, or alleged to be, materially untrue or incorrect. 
This indemnity will be in addition to any liability which the Seller may
otherwise have.

     (c)  Promptly after receipt by either the Purchasers or the Seller of
notice of the commencement of any action or proceeding in any way relating to or
arising from this Agreement, such party will notify the other party of the
commencement thereof; but the omission so to notify the party from whom
indemnification is sought (the "Indemnifying Party") will not relieve the
Indemnifying Party from any liability which it may have to the party seeking
indemnification (the "Indemnified Party") except to the extent that the
Indemnifying Party is adversely affected by the lack of notice.  In case any
such action is brought against the Indemnified Party, and it notifies the
Indemnifying Party of the commencement thereof, the Indemnifying Party will be
entitled to participate in the defense (with the consent of the 

                                       -12-

Indemnified Party which shall not be unreasonably withheld) of such action at

     SECTION 14.    TERMINATION.  This Agreement may be terminated (i) by the
mutual consent of the parties hereto, or (ii) by the Purchaser if the conditions
to the Purchaser's obligations to closing set forth under SECTION 10 hereof are
not fulfilled as and when required to be fulfilled or (iii) by the Seller if the
Purchaser's obligations under SECTION 11 hereof are not fulfilled as and when
required.  In the event of a termination pursuant to SECTION 14(ii), the Seller
agrees that it will pay the out-of-pocket fees and expenses of the Purchaser in
connection with the transactions contemplated by this Agreement and in the event
of a termination pursuant to SECTION 14(iii), the Purchaser agrees that it will
pay the out-of-pocket fees and expenses of the Seller in connection with the

     SECTION 17.    COUNTERPARTS.  This Agreement may be executed in any number
of counterparts, each of which shall be an original, but both of which together
shall constitute one and the same agreement.

     SECTION 18.    GOVERNING LAW.  This Agreement shall be deemed to have been

                                       -13-

reasonably request in order to effectuate the purpose and to carry out the 
terms of this Agreement.

     SECTION 20.    SUCCESSORS AND ASSIGNS.  This Agreement shall be binding
upon and inure to the benefit of and be enforceable by the Seller and the
Purchaser and their permitted successors and assigns.  The Seller acknowledges
and agrees that the Purchaser may assign its rights under this Agreement.  Any
person into which the Seller may be merged or consolidated (or any person

succeeding to the business of the Seller shall be considered the "successor" of
the Seller hereunder.  Except as provided in the two preceding sentences, this
Agreement cannot be assigned, pledged or hypothecated by any party hereto

            been lost, the Seller shall deliver or cause to be delivered to the

            true and correct copy;

            (b)  the original assignment to "Chase Bank of Texas, National

            has been sent for recordation.  Subject to the foregoing, such
            assignments may, if permitted by law, be by blanket assignments for
            Mortgage Loans covering Mortgaged Properties situated within the
            same county.  If the assignment

            is in blanket form, a copy of the assignment shall be included in
            the related individual Mortgage File;

     (iii)  the originals of any and all instruments that modify the terms and

     Re: ABN AMRO MORTGAGE CORPORATION PURCHASE OF MORTGAGE LOANS
         --------------------------------------------------------

Ladies and Gentlemen:

     As General Counsel to Standard Federal Bank, a federal savings bank 
("SELLER"), I and attorneys working under my supervision have acted as 
counsel to Seller in connection with the sale of Mortgage Loans by Seller to 
ABN AMRO Mortgage Corporation (the "PURCHASER") pursuant to a Mortgage Loan 
Purchase Agreement, dated as of October 27, 1998 (the "PURCHASE AGREEMENT"), 
between the Purchaser and Seller.  This opinion is being delivered to the 
Purchaser pursuant to SECTION 10(b)(iv) of the Purchase Agreement.  All 
capitalized terms not otherwise defined herein have the meanings given them 
in the Purchase Agreement.

     In rendering the opinions set forth below, we have examined and relied 
upon originals or copies, certified or otherwise identified to our 
satisfaction, of the charter and by-laws of Seller, the Purchase Agreement 
and such corporate records, agreements or other instruments of Seller, and 
such certificates, records and other documents, agreements and instruments, 
including, among other things, certain documents delivered on the Closing 
Date, as we have deemed necessary and proper as the basis for our opinions.  
In connection with such examination, we have assumed the genuineness of all 
signatures, the authenticity of all documents, agreements and instruments 
submitted to us as originals, the conformity to original documents, 
agreements and instruments of all documents, agreements and instruments 
submitted to us as copies or specimens, the authenticity of the originals of 
such documents, agreements and instruments submitted to us as copies or 
specimens, the conformity to executed original documents of all documents 
submitted to us in draft and the accuracy of the matters set forth in the 
documents we reviewed.  We have also assumed that all documents, agreements 
and instruments have been 

<PAGE>
ABN AMRO Mortgage Corporation
_____________ ___, 199_
Page 2


duly authorized, executed and delivered by all parties thereto.  As to any 
facts material to such opinions that we did not independently establish or 
verify, we have relied upon statements and representations of officers and 
other representatives of Seller as we have deemed necessary and proper as the 
basis for our opinions, including, among other things, the representations 
and warranties of Seller in the Purchase Agreement.

     Based upon the foregoing, I am of the opinion that:

     1.   Seller is a federal savings bank, duly organized, validly existing 
and in good standing under the laws of the United States and either is not 
required to be qualified to do business under the laws of any states where 
such qualification is necessary to transact the business contemplated by the 
Purchase Agreement, or is qualified to do business under the laws of any 
states where such qualification is necessary to transact the business 
contemplated by the Purchase Agreement, or is qualified to do business under 
the laws of any states where such qualification is necessary to transact the 
business contemplated by the Purchase Agreement, and Seller is duly 
authorized and has full corporate power and authority to transact the 
business contemplated by the Purchase Agreement.

     2.   The Purchase Agreement has been duly authorized, executed and 
delivered by Seller and is a legal, valid and binding obligation of and is 
enforceable against Seller in accordance with its terms, except that the 
enforceability thereof may be subject to (A) bankruptcy, insolvency, 
receivership, conservatorship, reorganization, moratorium or other laws, now 
or hereafter in effect, relating to creditors' rights generally or the right 
of creditors of federal savings banks, (B) general principles of equity 
(regardless of whether enforcement is sought in a proceeding in equity or at 
law) and (C) limitations of public policy under applicable securities laws as 
to rights of indemnity and contribution under the Purchase Agreement.

     3.   No consent, approval, authorization or order of any court or 
supervisory, regulatory, administrative or governmental agency or body is 
required for the execution, delivery and performance by Seller of or 
compliance by Seller with the Purchase Agreement, the sale of the Mortgage 
Loans or the consummation of the transactions contemplated by the Purchase 
Agreement.

     4.   Neither the execution and delivery by Seller of the Purchase 
Agreement, nor the consummation by Seller of the transactions contemplated 
therein, nor the compliance by Seller with the provisions thereof, will 
conflict with or result in a breach of any of the terms, conditions or 
provisions of Seller's charter or by-laws or board or shareholder's 
resolutions, or any agreement or instrument to which Seller is now a party or 
by which it is bound, or constitute a

Page 3


default or result in an acceleration under any of the foregoing, or result in 
the violation of any law, rule, regulation, order, judgment or decree to 
which Seller or its property is subject, which, in any of the above cases, 
would materially and adversely affect Seller's ability to perform its 
obligations under the Purchase Agreement.

     5.   There is not an action, suit, proceeding or investigation pending, 
or, to the best of my knowledge, threatened against Seller which, either in 
any one instance or in the aggregate, would draw into question the validity 
of the Purchase Agreement or the Mortgage Loans or of any action taken or to 
be taken in connection with the obligations of Seller contemplated therein, 
or which would be likely to materially impair the ability of Seller to 
perform under the terms of the Purchase Agreement.

     The Opinions expressed herein are limited to matters of federal and 
Michigan law and do not purport to cover any matters as to which laws of any 
other jurisdiction are applicable.  Except as expressly provided herein, this 
opinion is being furnished to you solely for your benefit in connection with 
the purchase of the Mortgage Loans, and it is not to be used, circulated, 
quoted or otherwise referred to for any purpose without my express written 
consent.

                                   Sincerely,


                                   Standard Federal Bank
