      This Pooling and Servicing Agreement, dated and effective as of July 1,
1999 (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 July 26, 1999, and a Prospectus Supplement, dated July 26, 1999, 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 July 27, 1999. 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

                        ORIGINAL ISSUANCE OF CERTIFICATES

      Section 2.1 Conveyance of Trust Fund. The Depositor, concurrently with the

to the Trustee and REMIC I 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

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

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

      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:

      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


                                       36




<PAGE>

      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

      recordation. Subject to the foregoing, such assignments may, if permitted

      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

      in the case of a delay caused by the public recording office, an Officer's

      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 mortgagee 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


                                       37




<PAGE>

      original title commitment or a copy thereof certified by the title company

            (vi) The mortgage insurance certificate;

      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 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


                                       38




<PAGE>

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 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 perfected 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 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 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


                                       40




<PAGE>

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 each
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 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:

      of, or agreement with, any other party, to sell and assign the same;

      paid and all taxes and governmental assessments previously due and owing,
      and which may become a lien against the Mortgaged Property, with respect
      to the Mortgaged Property have been paid;

            (viii) that each Mortgage Note and the related Mortgage are genuine
      and each is the legal, valid and binding obligation of the maker thereof,
      enforceable in accordance with its terms except as such enforcement may be
      limited by bankruptcy, insolvency, reorganization or other similar laws
      affecting the enforcement of creditors' rights generally and by general

      insuring the originator, its successor and assigns, as to the lien of the
      Mortgage in the original principal amount of the Loan subject only to (a)
      the lien of current real property taxes and assessments not yet due and
      payable, (b) covenants, conditions and restrictions, rights of way,
      easements and other

      matters of public record as of the date of recording of such Mortgage
      acceptable to mortgage lending institutions in the area in which the
      Mortgaged Property is located or specifically referred to in the appraisal
      performed in connection with the origination of the related Loan and (c)
      such other 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;

            (x) that as of the initial issuance of the Certificates, neither the
      Depositor nor any prior holder of any Mortgage has, except as the Mortgage
      File may reflect, modified the Mortgage in any material respect;

      and except for payment delinquencies not in excess of 30 days, to 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

      instruments for the state in which the Mortgaged Property is located;

            (xv) that based upon a representation by each Mortgagor at the time
      of origination or assumption of the applicable Loan, 100% of the Loans

<PAGE>

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

            (xix) 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 (ii) a
      mortgagee approved by the Secretary of Housing and Urban Development

            (xx) each Loan is a "qualified mortgage" within the meaning of
      Section 860G of the Code without regard to ss. 1.860G-2(f) of the REMIC
      Provisions or any similar rule;

            (xxi) each Loan that has a Loan-to-Value Ratio in excess of 80% is
      covered by a primary mortgage insurance policy; and

            (xxii) that no Loan permits negative amortization or the deferral of
      accrued interest.

      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, 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 each 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


                                       44




<PAGE>

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 the Depositor, 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 the Subordinate Certificates. The "residual interest"
      (within the meaning of Section 860G(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 a single Pre-Strip Regular Interest, the Class
      A-2 Regular Interest, the Class A-3 Regular Interest, the Class A-4
      Regular Interest, a single Pre- Inversion Regular Interest, the Class A-8
      Regular Interest, the Class A-9 Regular Interest, the Class A-10 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 "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. (The
      Pre-Strip Regular Interest shall consist of a single REMIC I Regular
      Interest, which shall correspond as to principal amount to the Class A-1
      Certificates.) (The Pre-Inversion Regular Interest shall consist of a
      single REMIC I Regular Interest which shall correspond as to principal
      amount to the sum of the principal amounts of the Class A-6 and Class A-7
      Certificates.)

            (c) All payments with respect to each of the Class A-2, A-3, A-4,
      A-8, A-9, A-10, A-X, A-P, M, B-1, B-2, B-3, B-4 and B-5 Certificates shall
      each be considered to have been


                                       45




<PAGE>

      made solely from the Regular Interest of REMIC I having the same
      designation. All payments with respect to the Class A-1 and Class A-5
      Certificates shall be considered to have been made solely from the
      Pre-Strip Regular Interest of REMIC I. All payments with respect to the
      Class A-6 and Class A-7 Certificates shall be considered to have been made
      solely from the Pre-Inversion Regular Interest of REMIC I.

            The interest rate of each of the REMIC I Regular Interest Classes
      A-2, A-3, A-4, A-8, A-9, A-10, 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 of REMIC II
      having the same designation. The Class A-P Regular Interest Class shall
      not bear interest, but will receive principal only in respect of the
      Loans.

            The Pre-Strip Regular Interest shall have an interest rate of 6.75%.
      The Pre-Inversion Regular Interest shall have an interest rate of 6.75%.

            The principal balance of each of the Regular Interests of REMIC I
      (except the Class A-X Regular Interest, the Pre-Inversion Regular Interest
      and Pre-Strip Regular Interest) is equal at all times to the Class
      Principal Balance of the Class of REMIC II which has the same designation.
      The notional principal balance of the Class A-X Regular Interest is equal
      at all times to the Class A-X Notional Amount. The principal balance of
      the Pre-Strip Regular Interest is equal at all times to the principal
      balance of the Class A-1 Certificates. The principal balance of the
      Pre-Inversion Regular Interest is equal at all times to the sum of the
      principal balances of the Class A-6 and A-7 Certificates.

            (d) The Class A-5 Certificates of REMIC II shall for purposes of the
      REMIC provisions be deemed to have a notional principal balance that
      corresponds at all times to the principal balance of the Pre-Strip 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:


                                       46




<PAGE>

      (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

      (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


                                       47




<PAGE>

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 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


                                       48




<PAGE>

      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
'SS' 1.860E-2(a)(5) of the REMIC Provisions) as and when required 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.


                                       49

            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 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 the Trustee), 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


                                       50




<PAGE>

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.

      (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;


                                       51




<PAGE>

            (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.

      (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 each 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.


                                       52

      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;

      (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;


                                       53




<PAGE>

      (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.

      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; Escrow Accounts.

      (a) The Servicer shall establish and maintain one or more accounts (each,
an "Escrow Account") into which all Escrow Payments shall be deposited and in
which all Escrow Payments shall be retained. Escrow Accounts shall be Eligible
Accounts, and funds in the Escrow Account may be invested in Eligible
Investments. The Servicer shall notify the Trustee in writing of the location
and account number of each Escrow Account it establishes and shall notify the
Trustee prior to any subsequent change thereof. Withdrawals of amounts from an
Escrow Account may be made only to: (i) effect payment of taxes, assessments and
comparable items; (ii) refund to Mortgagors any sums that are determined to be
overages; (iii) pay interest, if required and as described below, to Mortgagors
on balances in the Escrow Account; (iv) withdraw interest or other income which
may lawfully be retained by the Trust Fund, for deposit into the Certificate
Account; or (v) clear and terminate the Escrow Account at the termination of
this Agreement in accordance with Section 9.1. Unless otherwise required by
applicable law, any interest earned on funds in Escrow Accounts shall be
remitted to the related Mortgagors if required by the related Mortgage Note or
otherwise to the Servicer.

      (b) 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


                                       54




<PAGE>

makes pursuant to the preceding sentence, together with interest thereon at the
Federal Funds 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 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


                                       55




<PAGE>

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 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


                                       56




<PAGE>

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 expenses will increase the Liquidation Proceeds to
Certificateholders after reimbursement to itself for such expenses and (ii) that
such expenses 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)


                                       57




<PAGE>

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 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


                                       58




<PAGE>

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 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


                                       59




<PAGE>

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


                                       60




<PAGE>

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 March 15 of each year, beginning March 15, 2000, 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 each Rating
Agency and to any Certificateholder upon request by the Servicer, or by the
Trustee at the Servicer's expense.

      Section 3.12 Annual Independent Public Accountants' Servicing Report. On
or before March 15 of each year, beginning March 15, 2000, 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 each 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 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.

      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.


                                       61




<PAGE>

      (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 Defaulted
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.

            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


                                       62




<PAGE>

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 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 at least a 75%
Percentage Interest of the most subordinate class of Subordinate Certificates
then outstanding or a holder of a class of securities representing interests in
such Class of Subordinate 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


                                       63




<PAGE>

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 may 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
Subordinate Certificates in reverse order of seniority until each of their Class
Principal Balances have been reduced to zero and (b) second, to the Senior
Certificates (other than the Principal Only Certificate and the Interest Only
Certificate), pro rata, according to their Class Principal Balances in reduction
of their respective Class Principal Balances, as applicable; provided, however,
that if the loss is recognized with respect to a Discount Loan, the Discount
Fraction of such loss will first 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 Subordinate
Certificates in reverse order of seniority, in reduction of accrued but unpaid
interest thereon and then in reduction of the Class Principal Balance of such
Certificates and (b) second, to the Senior Certificates (other than the
Principal Only Certificate), 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 Balance.

      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 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
CutOff 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 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.

                             STATEMENTS AND REPORTS

      Section 4.1 Distributions to Certificateholders. (a) The Trustee shall
establish and maintain a separate account as set forth in Article I (the

Servicer and to make distributions to the Certificateholders of the amounts set
forth in this Section 4.1.

            (b) On each Distribution Date, the Trustee or the Paying Agent, if
      any, shall (i) withdraw from the Certificate Account the Available
      Distribution Amount for such Distribution Date and shall distribute to
      each Certificateholder, from the amount so withdrawn and to the extent of
      the Available Distribution Amount, such Certificateholder's share (based
      on the aggregate Percentage Interests represented by the Certificates of
      the applicable Class held by such Certificateholder) of the amounts and in
      the order of priority as set forth in the definition of "Certificate
      Distribution Amount", and (ii) distribute Excess Liquidation Proceeds to
      the Class R Certificateholder by wire transfer in immediately available
      funds for the account of the Certificateholder, or by any other means of
      payment acceptable to each Certificateholder of record on the immediately
      preceding Record Date (other than as provided in Section 9.1 respecting
      the final distribution), as specified by each such Certificateholder and
      at the address of such Holder appearing in the Certificate Register;
      provided, that if the Trustee has appointed a Certificate Administrator,

            (c) All reductions in the Certificate Principal Balance of a
      Certificate effected by distributions of principal or allocations of

      be binding upon all Holders of such Certificate and of any Certificate
      issued upon the registration of transfer or exchange therefor or in lieu
      thereof, whether or not such distribution is noted on such Certificate.
      The final distribution of principal of each Certificate (and the final
      distribution with respect to the Class R Certificate upon termination of
      the Trust Fund) shall be payable in the manner provided above only upon
      presentation and surrender thereof on or after the Distribution Date
      therefor at the office or agency of the Trustee or Certificate
      Administrator, if any, specified in the notice delivered pursuant to
      Section 4.1(d) or Section 9.1.

            (d) Whenever, on the basis of Curtailments, Payoffs and Monthly
      Payments on the Loans and Insurance Proceeds and Liquidation Proceeds
      received and expected to be received during the applicable Prepayment
      Period, the Trustee believes, or the Certificate Administrator, if any,
      has notified the Trustee that it believes, that the entire remaining
      unpaid Class Principal Balance of any Class of Certificates will become
      distributable on the next Distribution Date, the Trustee or the
      Certificate Administrator, if any, shall, no later than the Determination
      Date of the

                  (i) it is expected that funds sufficient to make such final
            distribution will be available in the Certificate Account on 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 or
            agency of the Certificate Registrar maintained for such purpose (the
            address of which shall be set forth in such notice), and (B) no
            interest shall accrue on such Certificate after such Distribution
            Date.

      Section 4.2 Statements to Certificateholders. (a) Not later than three (3)
days prior to each Distribution Date, the Servicer shall forward to the Trustee

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

      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.


                                       67




<PAGE>

      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 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


                                       68




<PAGE>

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
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


                                       69




<PAGE>

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

                                    ARTICLE V

                                THE CERTIFICATES

      Section 5.1 The Certificates.

      (a) The Certificates shall be substantially in the forms set forth in
Exhibits A and B attached hereto, and shall be executed by the Trustee,
authenticated by the Trustee (or any duly appointed Authenticating Agent) and
delivered to or upon the order of the Depositor upon receipt by the Trustee of
the documents specified in Section 2.1. The Certificates shall be issuable in
Authorized Denominations evidencing Percentage Interests. Certificates shall be
executed by manual or facsimile signature on behalf of the Trustee by authorized
officers of the Trustee. Certificates bearing the manual or facsimile signatures
of individuals who were at the time of execution the proper officers of the
Trustee shall bind the Trustee, notwithstanding that such individuals or any of
them have ceased to hold such offices prior to the authentication and delivery
of such Certificates or did not hold such offices at the date of such
Certificates. No Certificate shall be entitled to any benefit under this
Agreement, or be valid for any purpose, unless there appears on such Certificate
a certificate of authentication substantially in the form provided for herein
executed by the Trustee or any Authenticating Agent by manual signature, and
such certificate upon any


                                       71




<PAGE>

Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder. All
Certificates shall be dated the date of their authentication.

      (b) The following definitions apply for purposes of this Section 5.1:
"Disqualified Organization" means any Person which is not a Permitted
Transferee, but does not include any "Pass-Through Entity" which owns or holds a
Residual Certificate and of which a Disqualified Organization, directly or
indirectly, may be a stockholder, partner or beneficiary; "Pass-Through Entity"
means any regulated investment company, real estate investment trust, common
trust fund, partnership, trust or estate, and any organization to which Section
1381 of the Code applies; "Ownership Interest" means, with respect to any
Residual Certificate, any ownership or security interest in such Residual
Certificate, including any interest in a Residual Certificate as the Holder
thereof and any other interest therein whether direct or indirect, legal or
beneficial, as owner or as pledgee; "Transfer" means any direct or indirect
transfer or sale of, or directly or indirectly transferring or selling, any
Ownership Interest in a Residual Certificate; and "Transferee" means any Person
who is acquiring by Transfer any Ownership Interest in a Residual Certificate.

      (c) Restrictions on Transfers of the Residual Certificate to Disqualified
Organizations are set forth in this Section 5.1(c).

            (i) Each Person who has or who acquires any Ownership Interest in a
      Residual Certificate shall be deemed by the acceptance or acquisition of
      such Ownership Interest to have agreed to be bound by the following
      provisions and to have irrevocably authorized the Trustee, the Certificate
      Administrator or the Paying Agent under clause (iii)(A) below to deliver
      payments to a Person other than such Person and to negotiate the terms of
      any mandatory sale under clause (iii)(B) below and to execute all
      instruments of transfer and to do all other things necessary in connection
      with any such sale. The rights of each Person acquiring any Ownership
      Interest in a 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 not


                                       72




<PAGE>

                  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


                                       73




<PAGE>

      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.


                                       74

            (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 certificate
                  of the Depositor), to the effect that such 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 Certificates:

                        ANY RESALE, TRANSFER OR OTHER DISPOSITION OF THIS
                        CERTIFICATE MAY BE MADE ONLY IF THE PROPOSED TRANSFEREE
                        PROVIDES A TRANSFER AFFIDAVIT TO THE DEPOSITOR, THE
                        TRUSTEE AND THE CERTIFICATE REGISTRAR THAT (1) SUCH
                        TRANSFEREE IS NOT EITHER (A) THE UNITED STATES, ANY
                        STATE OR POLITICAL SUBDIVISION THEREOF, ANY FOREIGN
                        GOVERNMENT, ANY INTERNATIONAL ORGANIZATION, OR ANY
                        AGENCY OR INSTRUMENTALITY OF ANY OF THE FOREGOING, (B)
                        ANY ORGANIZATION (OTHER THAN A COOPERATIVE DESCRIBED IN
                        SECTION 521 OF THE CODE) WHICH IS EXEMPT FROM THE TAX
                        IMPOSED BY CHAPTER 1 OF THE CODE UNLESS SUCH

"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
an "insurance company general account" (within the meaning of Department of
Labor Prohibited Transaction Class Exemption ("PTCE") 95-60) to effect such

Sections I and III of PTCE 95-60, which Officer's Certificate shall 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
      Book-Entry Certificates, each Person who has or who acquires any Class M
      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

disposition is made in accordance with this Section 5.1(e)


                                       76




<PAGE>
or Section 5.1(f). 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
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 each Rating Agency. Notwithstanding the
foregoing, any Class of Junior Subordinate Certificates 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 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


                                       77




<PAGE>

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, initial Component 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 the Trustee or any Authenticating Agent) be duly
endorsed by, or be


                                       78




<PAGE>

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 canceled 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:


                                       80




<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 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, 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,

the obligations specifically imposed by this Agreement and undertaken hereunder

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

      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 each 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 each 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 in
accordance with Section 7.5 hereof, and (iv) the then-current rating of


                                       83

(v) the successor servicer 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.

      debt, marshaling 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 marshaling 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;


                                       84




<PAGE>

            (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 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 each 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


                                       85




<PAGE>

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 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 each 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


                                       86




<PAGE>

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 and in its capacity as
such successor shall have the same limitation 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 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 Sections 2.2 and 2.3 hereof,
which shall remain obligations of the


                                       87




<PAGE>

Depositor) to the qualified party submitting the highest qualifying bid. The
Trustee shall deduct all costs and 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 each 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


                                       88




<PAGE>

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 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 each 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


                                       89




<PAGE>

            (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 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 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;


                                       90




<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


                                       91




<PAGE>

taking of any action in good faith pursuant to this Agreement, or for errors in
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 combined capital and


                                       92




<PAGE>

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
each 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 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


                                       93




<PAGE>

become fully vested with all the rights, powers, duties and obligations of its
predecessor hereunder, with like effect as if originally named as trustee
herein. The predecessor trustee shall 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 each 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
separate trustee hereunder shall not be required to meet the terms of
eligibility as a successor trustee under Section 8.7 hereunder and no notice to
holders of Certificates of the appointment of co-trustee(s) or separate
trustee(s) shall be required under Section 8.9 hereof.


                                       94




<PAGE>

      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 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 Bank National Association. 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.


                                       95




<PAGE>

      (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 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, sign and


                                       96




<PAGE>

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 25 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.

      Section 8.16 Calculation of LIBOR. Until the Principal Balance of each of
the Adjustable Rate Certificates has been reduced to zero, the Trustee or the
Certificate Administrator, if any, shall establish LIBOR on each LIBOR
Determination Date as follows:

      (a) If on such LIBOR Determination Date a rate for United States dollar
deposits for one month appears on the Dow Jones Telerate System, page 3750,
LIBOR for the next Interest Accrual Period shall be equal to such rate as of
11:00 A.M., London time;

      (b) If such rate does not appear on such page (or such other page as may
replace that page on that service, or if such service is no longer offered, such
other service for displaying LIBOR or comparable rates as may be selected by the
Trustee or the Certificate Administrator, if any, after consultation with the
Servicer), the rate shall be determined as follows:

                  (i) The Trustee on the LIBOR Determination Date will request
            the principal London offices of each of four major reference banks
            in the London interbank market, as selected by the Trustee, to
            provide the Trustee with its offered quotation for deposits in
            United States dollars for the upcoming one-month period, commencing
            on the second LIBOR Business Day immediately following such LIBOR
            Determination Date, to prime banks in the London interbank market at
            approximately 11:00 a.m. London time on such LIBOR Determination
            Date and in a principal amount that is representative for a single
            transaction in United States dollars in such market at such time. If
            at least two such quotations are provided, LIBOR determined on such
            LIBOR Determination Date will be the arithmetic mean of such
            quotations.

                  (ii) If fewer than two quotations are provided, LIBOR
            determined on such LIBOR Determination Date will be the arithmetic
            mean of the rates quoted at approximately 11:00 a.m. in New York
            City on such LIBOR Determination Date by three major banks in New
            York City selected by the Trustee for one-month United States dollar
            loans to leading European banks, in a principal amount that is
            representative for a single transaction in United States dollars in
            such market at such time; provided, however, that if the banks so
            selected by the Trustee are not quoting as mentioned in this
            sentence, LIBOR determined on such LIBOR Determination Date will
            continue to be LIBOR as then currently in effect on such LIBOR
            Determination Date.


                                       97




<PAGE>

      (c) The establishment of LIBOR on each LIBOR Rate Adjustment Date by the
Trustee or the Certificate Administrator, if any, and the Trustee's or
Certificate Administrator's calculation of the rate of interest applicable to
the Class A-6 and Class A-7 Certificates for the related Interest Accrual Period
shall (in the absence of manifest error) be final and binding.

                                   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 each 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 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


                                       98




<PAGE>

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 each 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 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 Custodian 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, (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 or (c) such amendment is made to conform the terms of this
Agreement to the terms described in the Prospectus dated July 26, 1999, together
with the Prospectus Supplement dated July 26, 1999.

      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


                                      100




<PAGE>

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
66-2/3% 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 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 Holder
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 each 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 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

STATE OF       )

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 organization is


                                     J-1





<PAGE>

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 the 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 ______________, 19__.

                    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-mentioned 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,


                                      K-5




<PAGE>

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 (ii) the
purchase by the Class R Certificateholder of all Loans at a price established
pursuant to the Pooling Agreement; provided, however, that in no event shall the
trust created hereby continue beyond 21 years from the death of the survivor of
certain persons identified in the Pooling Agreement.

         NOW THEREFORE, in consideration of the premises and mutual agreements
hereinafter set forth, the Company, the Class B Holder and the Special Servicer
hereby agree as follows:

                                    ARTICLE I
                                    ---------

                                   DEFINITIONS
                                   -----------

         Section 1.01 Definitions Incorporated by Reference.

         Capitalized terms used but not otherwise defined in this Agreement
shall have the respective meaning ascribed thereto as set forth in the related
Pooling and Servicing Agreement [or the Servicer Guide, as the context may
require].

                                   ARTICLE II
                                   ----------

          DESIGNATION OF SPECIALLY SERVICED MORTGAGE LOANS AND SPECIAL
          ------------------------------------------------------------
                              SERVICING PROCEDURES
                              --------------------

         Section 2.01 [Approval of Litton Loan Servicing LP as an Approved
Servicer under the Servicer Guide.

         The Company hereby approves Litton Loan Servicing LP as an approved
servicer for all purposes under the terms of the Servicer Guide.]

         Section 2.02 Specially Serviced Mortgage Loans.

         To the extent and for so long as the Class B Certificates of a Series
are outstanding and the Class B Holder owns at least 75% of the most subordinate
outstanding class of the Class B Certificates of such Series (calculated by
dividing the then outstanding Certificate Principal Balance of such Class B
Certificates by the then outstanding Certificate Principal Balance of all
certificates of the same class ), Delinquent Mortgage Loans of the related
Series may, at the option of the Class B Holder, be designated in writing by the
Class B Holder as Specially Serviced Mortgage Loans and transferred to the
Special Servicer for servicing. The Special Servicer shall service the Specially
Serviced Mortgage Loans in accordance with the terms of the related Pooling and
Servicing Agreement [and the Servicer Guide].

         Following the designation of a Delinquent Mortgage Loan as a Specially
Serviced Loan, the Company shall transfer servicing of such Delinquent Mortgage
Loan to the Special Servicer substantially in the manner set forth herein and in
Schedule II hereto. [The parties hereto agree that any fees resulting from the
transfer of the servicing of a Delinquent Mortgage Loan from the Company or a
subservicer to the Special Servicer (or any successor thereto) shall be the
obligation of the Company.]
                                        2






<PAGE>




         As of the Effective Date (as defined below) of each Specially Serviced
Mortgage Loan, the Special Servicer shall succeed to and undertake all rights,
duties and obligations of the prior servicer (including, without limitation, the
making of advances, any right to purchase such Specially Serviced Mortgage Loan
at the purchase price set forth in the related Pooling and Servicing Agreement
and the right to receive the servicing fee with respect to such Specially
Serviced Mortgage Loan) pursuant to and in accordance with the terms of the
related Pooling and Servicing Agreement [and the terms and conditions of the
Servicer Guide].

         With respect to each Specially Serviced Mortgage Loan, the effective
date (the "Effective Date") shall be the first day of the month immediately
following the month of designation of such Specially Serviced Mortgage Loan as
such, provided that such written designation is received by the Company on or
prior to the 15" calendar day of such month.

         Once a Delinquent Mortgage Loan becomes a Specially Serviced Mortgage
Loan, such Delinquent Mortgage Loan shall remain a Specially Serviced Mortgage
Loan, and shall continue to be serviced by the Special Servicer, until the
earlier of the liquidation or other disposition of such Specially Serviced
Mortgage Loan or the termination of this Agreement, regardless of delinquency
status, whether the related Mortgaged Property becomes an REO Property or
otherwise; provided, however, that if the Company exercises its right as Master
Servicer to purchase all of the Mortgage Loans in a Trust Fund pursuant to an
optional termination provision under the related Pooling and Servicing
Agreement, the servicing of any related Specially Serviced Mortgage Loans with
respect to which foreclosure proceedings have not been commenced shall be
transferred promptly by the Special Servicer in accordance with written
instructions from the Company.

         If the Class B Holder (i) transfers such percentage interest in any
Class B Certificates of a Series such that the Class B Holder owns less than 75%
of the then outstanding Certificate Principal Balance of such class, or (ii)
purchases such percentage interest in any Class B Certificates of a Series such
that the Class B Holder owns 75% or more of the then outstanding Certificate
Principal Balance of such class, the Class B Holder shall promptly notify the
Company and the Special Servicer in writing of any such transfer or acquisition.
Upon receipt of written notice from the Class B Holder, the Company or the Class
B Holder shall revise Schedule I hereto to reflect any such transfer or
acquisition and shall forward promptly a copy of such revised schedule to the
Company or the Class B Holder, as applicable, and the Special Servicer. With
respect to the purchase of at least 75% of the Class B Certificates of any
Series by the Class B Holder after the date hereof, this Agreement shall be
effective as of the date such written notice of acquisition is received by the
Company.

         If and to the extent the Company is permitted to purchase Delinquent
Mortgage Loans under the related Pooling and Servicing Agreement, the Class B
Holder may direct the Company to purchase any Specially Serviced Mortgage Loan
and to promptly resell such Mortgage Loan to the Class B Holder at the price and
on the terms set forth in such Pooling and Servicing Agreement. In the event the
Class B Holder directs the Company to purchase a Specially Serviced Mortgage
Loan as permitted under this Section, the Company shall promptly take all

                                        3





<PAGE>



action necessary under the terms of the related Pooling and Servicing Agreement
in order to accomplish such purchase (i.e. provide notification to the Trustee
and/or Custodian) and to resell such Specially Serviced Mortgage Loan to the
Class B Holder. The Class B Holder, and not the Company, shall be required to
remit the purchase price for such Specially Serviced Mortgage Loan to the
related Trustee. The Company will inform the Trustee in writing of the purchase
of such Specially Serviced Mortgage Loan by the Class B Holder and further shall
promptly take all actions necessary or desirable to effect the conveyance of
such Mortgage Loan and the related servicing rights to the Class B Holder or its
designee, time being of the essence.

         Notwithstanding any provision herein to the contrary, the Special
Servicer shall (i) in no event be obligated to effect any cure or remedy in
connection with a deficiency in the documentation for any Specially Serviced
Mortgage Loan to the extent such deficiency existed at the time such Mortgage
Loan became a Specially Serviced Mortgage Loan or (ii) have any responsibility
for any obligations, duties, or liabilities of the Company with respect to the
servicing of a Specially Serviced Mortgage Loan that arose prior to the related
Effective Date for such Specially Serviced Mortgage Loan, other than those which
would customarily be assumed after the Effective Date.

         Section 2.03 Termination of Special Servicer for Default.

         The Company shall have the right, immediately upon written notice, to
terminate the Special Servicer's right and obligation to subservice all of the
Specially Serviced Mortgage Loans hereunder in the event (each such event, an
"Event of Default") of:

                  (i) any failure by the Special Servicer to remit to the
         Company for distribution to the Certificateholders of a Series any
         payment (including without limitation, any failure to make any required
         Advance) required to be made under the terms of this Agreement or the
         related Pooling and Servicing Agreement which continues unremedied for
         a period of one day after the date upon which written notice of such
         failure, requiring the same to be remedied, shall have been given to
         the Special Servicer by the Company; or

                  (ii) any failure on the part of the Special Servicer duly to
         observe or perform in any material respect any other of the covenants
         or agreements on the part of the Special Sub-Servicer contained in this
         Agreement (including any breach of the Special Servicer's
         representations and warranties contained in Section 4.03 hereof, which
         materially and adversely affects the interests of the
         Certificateholders of a Series) which continues unremedied for a period
         of 30 days after the date on which written notice of such failure,
         requiring the same to be remedied, shall have been given to the Special
         Servicer by the Company; or

                  (iii) a decree or order of a court or agency or supervisory
         authority having jurisdiction in an involuntary case under any present
         or future federal or state bankruptcy, insolvency or similar law or the
         appointment of a conservator or receiver or

<PAGE>



         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 Special
         Servicer and such decree or order shall have remained in force
         undischarged or unstayed for a period of 60 consecutive days; or

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

                  (v) the Special Servicer shall admit in writing its inability
         to pay its debts generally as they become due, file a petition to take
         advantage of or otherwise voluntarily commence a case or proceeding
         under any applicable bankruptcy, insolvency, reorganization or other
         similar statute, make an assignment for the benefit of its creditors,
         or voluntarily suspend payment of its obligations.

         If an Event of Default shall occur, then, and in each and every such
case, upon receipt of written notice from the Company, the Special Servicer
shall immediately remit to the Company all amounts in the Collection Accounts
and the Escrow Accounts and all rights of the Special Servicer to service the
Specially Serviced Mortgage Loans shall terminate. Following the receipt of
written notice from the Company as provided above, all authority and power of
the Special Sub-Servicer to subservice all the Specially Serviced Mortgage Loans
shall pass to and be vested in the Company pursuant to and under this Section
2.03, and the Special Servicer shall do all things necessary to effect a
transfer of the servicing rights back to the Company. In this regard, the
Company is hereby authorized and empowered to execute and deliver, on behalf of
the Special 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 affected
Specially Serviced Mortgage Loans and related documents, or otherwise. The
Special Servicer agrees to cooperate with the Company in implementing the
termination of the Special Servicer's responsibilities and rights hereunder,
including, without limitation, the transfer to the Company or its appointed
agent for administration by it of all amounts in the possession of the Special
Servicer or thereafter be received with respect to the Specially Serviced
Mortgage Loans and the transfer of the servicing rights back to the Company.

         Section 2.04  Appointment of Successor Special Servicer.

         The Class B Holder shall have the right, upon 90 days prior written
notice to the Company and the Special Servicer appoint a successor special
servicer having the characteristics set forth in clauses (i), (ii) and (iii)
below, and which shall succeed to all rights and assume all of the
responsibilities, duties and liabilities of the Special Servicer under this
Agreement simultaneously with the termination of the Special Servicer's
responsibilities, duties and liabilities under this Agreement. In the event that
the Special Servicer's duties, responsibilities


                                       5





<PAGE>



and liabilities under this Agreement should be terminated pursuant to the
foregoing, the Special Servicer shall discharge such duties and responsibilities
during the period from the date it acquires knowledge of such termination until
the effective date thereof with the same degree of diligence and prudence which
it is obligated to exercise under this Agreement, and shall take no action
whatsoever that might impair or prejudice the rights or financial condition of
its successor. The removal of the Special Servicer shall not become effective
until a successor shall be appointed pursuant to this Section and shall in no
event relieve the Special Servicer of the representations and warranties made
pursuant to Section 4.03 and the remedies available to the Class B Holder and/or
the Company under Sections 4.04 and 5.01, it being understood and agreed that
the provisions of such Sections 4.04 and 5.01 shall be applicable to the Special
Servicer notwithstanding any such termination of it, or the termination of this
Agreement.

Any successor special servicer shall (i) [be an institution having a net worth
of not less than $1,000,000][meet the eligibility requirements of an approved
servicer under the Company's Servicer Guide], (ii) the appointment of such
successor servicer will not result in the downgrading in any rating by any
applicable rating agency of any security issued in connection with the
applicable Pooling and Servicing Agreements, and (iii) have and keep in full
effect its existence, rights and franchises as a corporation (or such other
corporate form), and shall obtain its qualification to do business as a foreign
corporation (or such other corporate form) in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Agreement or any of the Specially Serviced Mortgage Loans
and to perform its duties under this Agreement. Any successor appointed as
provided herein shall execute, acknowledge and deliver to the Class B Holder and
the Company an instrument accepting such appointment, wherein the successor
shall make the representations and warranties set forth in Section 4.03,
whereupon such successor shall become fully vested with all the rights, powers,
duties, responsibilities, obligations and liabilities of the Special Servicer,
with like effect as if originally named as a party to this Agreement.

         Within 30 days of the appointment of a successor special servicer by
the Class B Holder, the Special Servicer shall prepare, execute and deliver to
the successor entity any and all documents and other instruments, place in such
successor's possession all servicing files related to the Specially Serviced
Mortgage Loans, and do or cause to be done all other acts or things necessary or
appropriate to effect the purposes of such notice of termination[, including but
not limited to the transfer and endorsement of the related Mortgage Notes and
other documents, and the Class B Holder shall do or cause to be done the
preparation and recordation of Assignments of Mortgage and Deeds at the Class B
Holder's sole expense].

         The Special Servicer shall cooperate with the Class B Holder and such
successor in effecting the termination of the Special Servicer's
responsibilities and rights hereunder and the transfer of servicing
responsibilities to the successor special servicer, including without
limitation, the transfer to such successor of all amounts received by it with
respect to the Specially Serviced Mortgage Loans. Further, the Special
Servicer shall execute and deliver such instruments and do such other things
as may reasonably be required to more fully and

                                       6

definitively vest in the successor all such rights, powers, duties,
responsibilities, obligations and liabilities of the Special Servicer.

written reports, documentation, instruments, certificates and correspondences
provided by a servicer under the terms of the

Servicer Guide with respect to any Mortgage Loan that becomes sixty (60) days or
more delinquent.

         (b) If requested by the Class B Holder, the Company shall make its
servicing personnel available to respond to reasonable inquiries, by phone or in
writing by facsimile, electronic, or overnight mail transmission, in connection
with any Mortgage Loan identified in any report or document provided pursuant to
clause (a) above; provided, that the Company shall only be required to provide
information that is reasonably accessible to its servicing personnel (or its
subservicers).

         (c) In addition to the information described above, the Company shall
provide to the Class B Holder such information as the Class B Holder may
reasonably request; provided, however, that the Mortgage Loans are Delinquent
Mortgage Loans or the Mortgaged Property has been foreclosed upon. The Class B
Holder will reimburse the Company for any reasonable out-of-pocket expenses
incurred by it in providing such information.

         Section 3.02 Servicing of Delinquent Mortgage Loans.

         (a) Prior to the Commencement of Foreclosure of any Mortgage Loan, the
Company shall provide, or cause the related servicer to provide, the Class B
Holder with a notice (sent by telecopier) of such proposed and imminent
foreclosure, stating the loan number and the aggregate amount due under the
Mortgage Note.

         For purposes of this Agreement, "Commencement of Foreclosure" shall
mean the first official action required under local law in order to commence
foreclosure proceedings or to schedule a trustee's sale under a deed of trust,
including (i) in the case of a mortgage, any filing or service of process
necessary to commence an action to foreclosure, or (ii) in the case of a deed of
trust, posting, the publishing, filing or delivery of a notice of sale, but not
including in either case (x) any notice of default, notice of intent to
foreclose or sell or any other action prerequisite to the actions specified in
(i) or (ii) above, (y) the acceptance of a deed-in-lieu of foreclosure (whether
in connection with a sale of the related property or otherwise) or (z)
initiation and completion of a short pay-off.

         (b) In connection with any Delinquent Mortgage Loan with respect to
which a notice under clause (a) above has been delivered to the Class B Holder,
the Class B Holder shall provide the Company with written direction as to the
action to be taken with respect to such Delinquent Mortgage Loan, including,
without limitation, to proceed with foreclosure, to accept a deed-in-lieu of
foreclosure, to consent to a pre-foreclosure sale of Mortgaged Property
at a loss, or, if permitted under the terms of the related Pooling and
Servicing Agreement, to purchase Delinquent Mortgage Loans. Such written
direction must be received by the Company within two (2) Business Days of
transmission of the notice provided by the Company under clause (a) above. Such
two (2) Business Day period shall be extended for no longer than an additional
three (3) Business Days after the receipt of additional information requested if
the Class B Holder requests additional information related to such Delinquent
Mortgage Loan;


                                       8





<PAGE>




provided, however that the Class B Holder will have at least one Business Day to
provide written direction after receipt of any requested additional information.
Any such additional information shall be provided only to the extent it is
obtainable by the Company from existing reports, certificates or statements or
otherwise be reasonably accessible to its servicing personnel (or subservicing
personnel). The Company shall as promptly as practicable carry out, or cause the
relevant servicer to carry out, the instruction of the Class B Holder in the
manner prescribed in such written direction. The Class B Holder agrees that it
has no right to negotiate directly with the Mortgagor during such period.

         In the event the Class B Holder fails to provide any written direction
as provided above, the Company may take any such action as would be consistent
with customary servicing practices of prudent mortgage loan servicers and the
Company's normal policies and practice.

         (c) With respect to any Delinquent Mortgage Loan for which the Company
has not provided a notice as contemplated in clause (a) above, the Class B
Holder may, at any time, provide the Company with written direction as to the
action to be taken with respect to such Delinquent Mortgage Loan, including,
without limitation, to commence foreclosure proceedings, to accept a
deed-in-lieu of foreclosure, to consent to a sale of Mortgaged Property at a
loss, or, if permitted under the terms of the related Pooling and Servicing
Agreement, to purchase Delinquent Mortgage Loans. To the extent such action is
not inconsistent with the terms of the related Pooling and Servicing Agreement
or the Company's duties thereunder as master servicer, the Company shall as
promptly as practicable carry out, or cause the relevant servicer to carry out,
the instruction of the Class B Holder in the manner prescribed in such written
direction.

         (d) Any foreclosure of a Delinquent Mortgage Loan that has been
initiated in accordance with clauses (b) or (c) above may be discontinued if (i)
the Mortgage Loan has been brought current or if a refinancing or prepayment
occurs with respect to the Mortgage Loan (including by means of a short payoff
approved by the Class B Holder), (ii) the Company has agreed to the terms of a
forbearance agreement with the Mortgagor and such forbearance agreement has been
approved by the Class B Holder, or (iii) if and to the extent permitted under
the related Pooling and Servicing Agreement, Class B Holder directs the Company
to purchase such Delinquent Mortgage Loan at the price and on the terms set
forth in the related Pooling and Servicing Agreement.

         (e) In the event the Class B Holder directs the Company to purchase a
Delinquent Mortgage Loan as permitted under Sections 2.02 and 3.02 (b), (c) and
(d), the Class B Holder may direct the Company to purchase any Delinquent
Mortgage Loan and to promptly resell such Mortgage Loan to the Class B Holder at
the price and on the terms set forth in the applicable Pooling and Servicing
Agreement. In the event the Class B Holder directs the Company to purchase a
Delinquent Mortgage Loan as permitted under this Section, the Company shall
promptly take all action necessary under the terms of the related Pooling and
Servicing Agreement in order to accomplish such purchase (i.e. provide
notification to the Trustee and/or Custodian) and to resell such Delinquent
Mortgage Loan to the Class B Holder. The Class B Holder, and not the Company,
shall be required to remit the purchase price for such Delinquent

                                       9

Mortgage Loan to the related Trustee. The Company will inform the Trustee in
writing of the purchase of such Delinquent Mortgage Loan by the Class B Holder
and further shall promptly take all actions necessary or desirable to effect the
conveyance of such Mortgage Loan and the related servicing rights to the Class B
Holder or its designee, time being of the essence. [The parties hereto agree
that, in connection with a purchase of a Delinquent Mortgage Loan as provided
above, any fees resulting from the transfer of the servicing of such purchased
Delinquent Mortgage Loan from the Company or a subservicer to a servicer
designated by the Class B Holder shall be the obligation of the Company.]


         Section 3.03 Review of the Company's Procedures.

         The Company and the Class B Holder hereby agree that the Class B Holder
shall have the right, at its own expense and during normal business hours, to
review any and all of the books, records, or other information of the Company
which may be relevant to the Company's direct collection, loss mitigation
foreclosure and REO management procedures currently in place in order to confirm
that the procedures used by the Company and its subservicers are in accordance
with the customary servicing practices of prudent mortgage loan servicers. In
order to discuss such books, records or other information, the Company shall
make personnel available who are knowledgeable about such matters.

                                   ARTICLE IV
                                   ----------

                         REPRESENTATIONS AND WARRANTIES
                         ------------------------------

         Section 4.01 Organizational and Other Related Warranties of the Class B
Holder. The Class B Holder hereby makes the following representations and
warranties to the Company and the Special Servicer:

                  (i) Organization and Good Standing. The Class B Holder is an
         entity duly organized, validly existing, and in good standing under the
         laws of its state of incorporation or formation or the laws of the
         United States.

                  (ii) No Violation. Neither the execution and delivery by the
         Class B Holder of this Agreement, nor the consummation by the Class B
         Holder of the transactions contemplated hereby, nor the performance of
         and compliance by the Class B Holder with the provisions of this
         Agreement, will conflict with or result in a breach or violation of, or
         constitute a default (or an event which, with notice or the lapse of
         time, or both, would constitute a default) under, the organizational
         documents (its articles of incorporation or charter or by-laws) of the
         Class B Holder, or any of the provisions of any law, rule, regulation,
         judgment, decree, demand, or order (of any federal, state, or local
         governmental or regulatory authority or court) binding on the Class B
         Holder, or any of its respective properties, or any of the provisions
         of any indenture, mortgage, contract, instrument, or other document to
         which the Class B Holder is a party or by which it is bound, or result
         in the creation or imposition of any lien, charge, or encumbrance upon

                                       10





<PAGE>




         any of their respective properties pursuant to the terms of any
         indenture, mortgage, contract, instrument, or other document. The Class
         B Holder is not otherwise in violation of any law, rule, regulation,
         judgment, decree, demand, or order (of any federal, state or local
         governmental or regulatory authority or court), which violation, in the
         Class B Holder's, good faith and reasonable judgment, is likely to
         affect materially and adversely its ability to perform its obligations
         hereunder.

                  (iii) Authorization and Enforceability. The execution and
         delivery by the Class B Holder of this Agreement, the consummation of
         the transactions contemplated hereby, and the performance and
         compliance by the Class B Holder with the terms hereof are within the
         powers of the Class B Holder, and have been duly authorized by all
         necessary action on the part of the Class B Holder. All organizational
         resolutions and consents necessary for the Class B Holder to enter into
         and consummate all transactions contemplated hereby have been obtained.
         This Agreement has been duly executed and delivered by the Class B
         Holder and constitutes the legal, valid and binding obligation of the
         Class B Holder, enforceable against it in accordance with its terms,
         subject to applicable bankruptcy, insolvency, reorganization,
         moratorium, and other similar laws affecting creditors' rights
         generally, and to general principles of equity, regardless of whether
         such enforcement is considered in a proceeding in equity or at law. The
         Class B Holder has not failed to obtain any consent, approval,
         authorization, or order of, or failed to cause any registration or
         qualification with, any court or regulatory authority or other
         governmental body having jurisdiction over it, which consent, approval,
         authorization, order, registration, or qualification is required for,
         and the absence of which would materially adversely affect, the legal
         and valid execution, delivery, and performance of this Agreement by the
         Class B Holder.

                  (iv) No Litigation or Adverse Conditions. No litigation is
         pending or, to the best of the Class B Holder's knowledge, threatened
         against it, which, if determined adversely to the Class B Holder would
         prohibit the Class B Holder from entering into this Agreement or, in
         the good faith and reasonable judgment of the Class B Holder, is likely
         to materially and adversely affect either the ability of the Class B
         Holder to perform its obligations hereunder.

         Section 4.02 Organizational and Other Related Warranties of the
Company. The Company hereby makes the following representations and warranties
to the Class B Holder and the Special Servicer:

                  (i) Organization and Good Standing. The Company is an entity
         duly organized, validly existing, and in good standing under the laws
         of its state of incorporation or formation or the laws of the United
         States, and is in compliance with the laws of each state in which any
         property is located to the extent necessary to ensure the
         enforceability of each Mortgage Loan and to perform its obligations
         hereunder and the Pooling and Servicing Agreement.

                  (ii) No Violation. Neither the execution and delivery by
         Company of this Agreement, nor the consummation by it of the
         transactions contemplated hereby, nor the performance of and compliance
         by the Company with the provisions hereof or of the Pooling and
         Servicing Agreement, will conflict with or result in a breach or
         violation of, or constitute a default (or an event which, with notice
         or the lapse of time, or both, would constitute a default) under, the
         organizational documents (its articles of incorporation or charter or
         by-laws) of the Company, or any of the provisions of any law, rule,
         regulation, judgment, decree, demand, or order (of any federal, state,
         or local governmental or regulatory authority or court) binding on the
         Company, or any of its properties, or any of the provisions of any
         indenture, mortgage, contract, instrument, or other document
         (including, without limitation, any Pooling and Servicing Agreement) to
         which the Company is a party or by which it is bound, or result in the
         creation or imposition of any lien, charge, or encumbrance upon any of
         their respective properties pursuant to the terms of any indenture,
         mortgage, contract, instrument, or other document. The Company is not
         otherwise in violation of any law, rule, regulation, judgment, decree,
         demand, or order (of any federal, state or local governmental or
         regulatory authority or court), which violation, in the Company's good
         faith and reasonable judgment, is likely to affect materially and
         adversely either its ability to perform its obligations hereunder or
         under the Pooling and Servicing Agreements, or the financial condition
         of the Company.

                  (iii) Authorization and Enforceability. The execution and
         delivery by the Company of this Agreement, the consummation of the
         transactions contemplated hereby, and the performance and compliance by
         the Company with the terms hereof and of the Pooling and Servicing
         Agreements are within the powers of the Company, and have been duly
         authorized by all necessary action on the part of the Company. All
         organizational resolutions and consents necessary for the Company to
         enter into and consummate all transactions contemplated hereby have
         been obtained. This Agreement has been duly executed and delivered by
         the Company and constitutes the legal, valid and binding obligation of
         the Company, enforceable against it in accordance with its terms,
         subject to applicable bankruptcy, insolvency, reorganization,
         moratorium, and other similar laws affecting creditors' rights
         generally, and to general principles of equity, regardless of whether
         such enforcement is considered in a proceeding in equity or at law. The
         Company has not failed to obtain any consent, approval, authorization,
         or order of, or failed to cause any registration or qualification with,
         any court or regulatory authority or other governmental body having
         jurisdiction over the Company, which consent, approval, authorization,
         order, registration, or qualification is required for, and the absence
         of which would materially adversely affect, the legal and valid
         execution, delivery, and performance of this Agreement by the Company.

                  (iv) Approvals and Permits. The Company possesses such
         certificates, authorizations, licenses, and permits issued by the
         appropriate state, federal, and foreign regulatory agencies or bodies
         necessary to conduct the business now operated by it, and the Company
         has not received any notice of proceedings relating to the revocation
         or modification of any such certificate, authorization, or permit
         which, singly or in the

                                       12

         aggregate, if the subject of an unfavorable decision, ruling, or
         finding, would materially and adversely affect the conduct of the
         business, operations, financial condition, or income of the Company.

                  (v) No Litigation or Adverse Conditions. No litigation is
         pending or, to the best of the Company's knowledge, threatened against
         it, which, if determined adversely to the Company would prohibit the
         Company from entering into this Agreement or, in the good faith and
         reasonable judgment of the Company, is likely to materially and
         adversely affect either its ability to perform its obligations
         hereunder or under the Pooling and Servicing Agreements or the
         financial condition of the Company. The Company has no knowledge of any
         recent adverse financial condition or event with respect to itself
         that, in its good faith and reasonable judgment, is likely to
         materially and adversely affect its ability to perform its obligations
         hereunder or under the Pooling and Servicing Agreements.

                  (vi) Fidelity Bond: Errors and Omission Insurance. Each
         officer, director, employee, consultant and advisor of the Company with
         responsibilities concerning the servicing and administration of the
         Mortgage Loans is covered by errors and omissions insurance and
         fidelity bond insurance in the amounts and with the coverage required
         under the related Pooling and Servicing Agreement for it to maintain.
         Neither the Company nor any of its officers, directors, employees,
         consultants, or advisors involved in the servicing or administration of
         the Mortgage Loans has been refused such coverage or insurance.

         entity duly organized, validly existing, and in good standing under the
         laws of its state of incorporation or formation or the laws of the

         which any property is located to the extent necessary to ensure the
         enforceability of each Mortgage Loan and to perform its obligations
         hereunder.

                  (ii) No Violation. Neither the execution and delivery by
         Special Servicer of this Agreement, nor the consummation by it of the
         transactions contemplated hereby, nor the performance of and compliance
         by the Special Servicer with the provisions hereof, will conflict with
         or result in a breach or violation of, or constitute a default (or an
         event which, with notice or the lapse of time, or both, would
         constitute a default) under, the organizational documents (its articles
         of incorporation or charter or by-laws) of the Special Servicer, or any
         of the provisions of any law, rule, regulation, judgment, decree,
         demand, or order (of any federal, state, or local governmental or
         regulatory authority or

                                       13

         court) binding on the Special Servicer, or any of its properties, or
         any of the provisions of any indenture, mortgage, contract, instrument,
         or other document to which the Special Servicer is a party or by which

         charge, or encumbrance upon any of their respective properties pursuant
         to the terms of any indenture, mortgage, contract, instrument, or other
         document. The Special Servicer is not otherwise in violation of any
         law, rule, regulation, judgment, decree, demand, or order (of any
         federal, state or local governmental or regulatory authority or court),
         which violation, in the Special Servicer's good faith and reasonable
         judgment, is likely to affect materially and adversely either its
         ability to perform its obligations hereunder, or the financial
         condition of the Special Servicer.

                  (iii) Authorization and Enforceability. The execution and
         delivery by the Special Servicer of this Agreement, the consummation of
         the transactions contemplated hereby, and the performance and

         powers of the Special Servicer, and have been duly authorized by all
         necessary action on the part of the Special Servicer. All
         organizational resolutions and consents necessary for the Special
         Servicer to enter into and consummate all transactions contemplated
         hereby have been obtained. This Agreement has been duly executed and

         proceeding in equity or at law. The Special Servicer has not failed to
         obtain any consent, approval, authorization, or order of, or failed to
         cause any registration or qualification with, any court or regulatory
         authority or other governmental body having jurisdiction over the
         Special Servicer, which consent, approval, authorization, order,
         registration, or qualification is required for, and the absence of
         which would materially adversely affect, the legal and valid execution,
         delivery, and performance of this Agreement by the Special Servicer.

                  (iv) Approvals and Permits. The Special Servicer possesses
         such certificates, authorizations, licenses, and permits issued by the
         appropriate state, federal, and foreign regulatory agencies or bodies

         modification of any such certificate, authorization, or permit which,
         singly or in the aggregate, if the subject of an unfavorable decision,
         ruling, or finding, would materially and adversely affect the conduct
         of the business, operations, financial condition, or income of the
         Special Servicer.

                  (v) No Litigation or Adverse Conditions. No litigation is
         pending or, to the best of the Special Servicer's knowledge, threatened
         against it, which, if determined adversely to the Special Servicer
         would prohibit the Special Servicer from entering into this Agreement
         or, in the good faith and reasonable judgment of the Special Servicer,
         is

         likely to materially and adversely affect either its ability to
         perform its obligations hereunder or the financial condition of the
         Special Servicer. The Special Servicer has no knowledge of any recent
         adverse financial condition or event with respect to itself that, in
         its good faith and reasonable judgment, is likely to materially and
         adversely affect its ability to perform its obligations hereunder.

         Department of Housing and Urban Development.

         Section 4.04 Remedies for Breach of Representation and Warranty.

         Upon discovery by any of the Company, the Class B Holder or the Special
Servicer of a breach of any of the representations and warranties contained in
Article IV which materially and adversely affects the value of the Specially
Serviced Mortgage Loans or Delinquent Mortgage Loans, the party discovering such
breach shall give prompt written notice to the others.

         Each of the parties hereto shall indemnify the others and hold each of

__, 1999 (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 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 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

                                        2

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.

     SECTION 7. Further Actions; Financing Statements.

     (a) In furtherance of the provisions of Section 5(c) hereof, 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

               (t) each Mortgage Loan is a "qualified mortgage" within the
         meaning of Section 860G of the Internal Revenue Code of 1986, without
         regard to ss.1.860 G-2(f) of the REMIC provisions or any similar rule;

               (u) each Mortgage Loan that has a Loan-to-Value Ratio at

         policy; and

               (v) that no Mortgage Loan permits negative amortization or the
         deferral of accrued interest.

         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

     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,

     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

     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 12 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.

     agreement or other material agreement or instrument to which the Purchaser
     is a party or by which the Purchaser or to which any property or assets of
     the Purchaser is subject;

     delivery by the Seller, constitutes a valid and legally binding obligation
     of the Purchaser, enforceable against the Purchaser in accordance with its
     terms, subject, as to enforcement, to bankruptcy, insolvency,
     reorganization and other similar laws of general applicability relating to
     or affecting creditors' rights and to general equity principles, regardless
     of whether such enforcement is considered in a proceeding in equity or at
     law;

         (iv) The Purchaser 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 the Purchaser default might
     have consequences that would materially and adversely affect the condition
     (financial or other) or operations of the Purchaser or its properties or
     might have consequences that would affect its performance hereunder; and

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

     SECTION 10. Purchaser's Conditions to Closing. The obligations of the
Purchaser under this Agreement shall be subject to the satisfaction, on or prior

prior to the Closing Date pursuant to the terms of this Agreement shall have
been duly performed and complied with and all of the representations and
warranties of the Seller under this Agreement shall be true and correct as of

action is brought against the Indemnified Party, and it notifies the

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

                         PURSUANT TO SECTION 10(b)(iv)]



                               __________ __, 1999

         Re: ABN AMRO Mortgage Corporation Purchase of Mortgage Loans

Ladies and Gentlemen:

         As General Counsel to ABN AMRO Mortgage Group, Inc., a Delaware
Corporation ("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 _________ ___, 1999 (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 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 a Delaware corporation, (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

Page 3


agreement or instrument to which Seller is now a party or by which it is bound,
or constitute a 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,


                                            ABN AMRO Mortgage Group, Inc.
