              ------------------------                                    
Underwriters propose to offer the Offered Certificates for sale to the public as
set forth in the Prospectus.

          5.  Agreements. The Company agrees with the several Underwriters that:
              ----------
          (a) The Company will promptly advise the Underwriters (i) when any
amendment to the Registration Statement shall have become effective, (ii) of any
request by the Commission for any amendment to the Registration Statement or the
Prospectus or for any additional information, (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement affecting the Offered Certificates or the institution or threatening
of any proceeding for that purpose and (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification of the Offered
Certificates for sale in any jurisdiction or the initiation or threatening of
any proceeding for such purpose.  The Company will not file any amendment to the
Registration Statement or supplement to the Prospectus unless the Company has
furnished you a copy for your review prior to filing and will not file any such
proposed amendment or supplement to which you reasonably object until after the
period in which a prospectus is required to be delivered to purchasers of the
Offered Certificates under the Act.  Subject to the foregoing sentence, the
Company will cause the Prospectus Supplement to be mailed to the Commission for
filing 

                                      -5-

 
pursuant to Rule 424 under the Act by first-class certified or registered
mail or to be filed with the Commission in another manner pursuant to said Rule.
The Company will use its best efforts to prevent the issuance of any such stop
order and, if issued, to obtain as soon as possible the withdrawal thereof.

          (b) The Company will cause any Computational Materials and any
Structural Term Sheets (each as defined in Section 9 below) with respect to the
Offered Certificates of a Series that are delivered by an Underwriter to the
Company pursuant to Section 9 to be filed with the Commission on a Current
Report on Form 8-K (a "Current Report") pursuant to Rule 13a-11 under the
                       --------------                                    
Exchange Act on the business day immediately following the later of (i) the day
on which such Computational Materials and Structural Term Sheets are delivered
to counsel for the Company by an Underwriter prior to 10:30 a.m. and (ii) the
date on which this Agreement is executed and delivered.  The Company will cause
one Collateral Term Sheet (as defined in Section 10 below) with respect to the
Offered Certificates of a Series that is delivered by the Underwriters to the
Company in accordance with the provisions of Section 10 to be filed with the
Commission on a Current Report pursuant to Rule 13a-11 under the Exchange Act on
the business day immediately following the day on which such Collateral Term
Sheet is delivered to counsel for the Company by the Underwriters prior to 10:30
a.m. In addition, if at any time prior to the availability of the Prospectus
Supplement, the Underwriters have delivered to any prospective investor a
subsequent Collateral Term Sheet that reflects, in the reasonable judgment of
the Underwriters and the Company, a material change in the characteristics of
the Mortgage Loans for the Series from those on which a Collateral Term Sheet
with respect to the Series previously filed with the Commission was based, the
Company will cause any such Collateral Term Sheet that is delivered by the
Underwriters to the Company in accordance with the provisions of Section 10 to
be filed with the Commission on a Current Report on the business day immediately
following the day on which such Collateral Term Sheet is delivered to counsel
for the Company by the Underwriters prior to 10:30 a.m. In each case, the
Company will promptly advise the Underwriters when such Current Report has been
so filed.  Each such Current Report shall be incorporated by reference in the
Prospectus and the Registration Statement.  Notwithstanding the five preceding
sentences, the Company shall have no obligation to file any materials provided
by the Underwriters pursuant to Section 9 and 10 which, in the reasonable
determination of the Company, are not required to be filed pursuant to the
Kidder Letters or the PSA Letter (each as defined in Section 9 below), or
contain erroneous information or contain any untrue statement of a material fact
or, when read in conjunction with the Prospectus and Prospectus Supplement, omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading; it being understood, however, that the
Company shall have no obligation to review or pass upon the accuracy or adequacy
of, or to correct, any Computational Materials, Structural Term Sheets or
Collateral Term Sheets provided by the Underwriters to the Company pursuant to
Section 9 or Section 10 hereof.  The Company shall give notice to the
Underwriters of its determination not to file any materials pursuant to clause
(i) of the preceding sentence and agrees to file such materials if the
Underwriters reasonably object to such determination within one business day
after receipt of such notice.

                                      -6-

 
          (c) If, at any time when a prospectus relating to the Offered
Certificates is required to be delivered under the Act, any event occurs as a
result of which the Prospectus as then amended or supplemented would include any
untrue statement of a material fact or omit to state any material fact necessary
to make the statements therein in the light of the circumstances under which
they were made not misleading, or if it shall be necessary to amend or
supplement the Prospectus to comply with the Act or the rules under the Act, the
Company promptly will prepare and file with the Commission, subject to paragraph
(a) of this Section 5, an amendment or supplement that will correct such
statement or omission or an amendment that will effect such compliance and, if
such amendment or supplement is required to be contained in a post-effective
amendment to the Registration Statement, will use its best efforts to cause such
amendment of the Registration Statement to be made effective as soon as
possible; provided, however, that the Company will not be required to file any
such amendment or supplement with respect to any Computational Materials,
Structural Term Sheets or Collateral Term Sheets incorporated by reference in
the Prospectus other than any amendments or supplements of such Computational
Materials, Structural Term Sheets or Collateral Term Sheets that are furnished
to the Company pursuant to Section 9(e) hereof which the Company determines to
file in accordance therewith.

          (d) The Company will furnish to the Underwriters and counsel for the
Underwriters, without charge, signed copies of the Registration Statement
(including exhibits thereto) and to each other Underwriter a copy of the
Registration Statement (without exhibits thereto) and, so long as delivery of a
prospectus by an Underwriter or dealer may be required by the Act, as many
copies of the Basic Prospectus, the Preliminary Prospectus supplement, if any,
and the Prospectus Supplement and any amendments and supplements thereto as the
Underwriters may reasonably request.

          [(e)  The Company agrees that, so long as the Offered Certificates
shall be outstanding, it will cause the Trustee to deliver to the Underwriters
the annual statement as to compliance and the annual statements of a firm of
independent public accountants, furnished to the Trustee by the Servicer
pursuant to Section[s] __________________ of the Pooling and Servicing
Agreement, as soon as such statements are furnished to the Trustee.]

          (f) The Company will furnish such information, execute such
instruments and take such action, if any, as may be required to qualify the
Offered Certificates for sale under the laws of such jurisdictions as the
Underwriters may designate and will maintain such qualification in effect so
long as required for the distribution of the Offered Certificates; provided,
however, that the Company shall not be required to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action that would
subject it to general or unlimited service of process in any jurisdiction where
it is not now so subject.

          [(g)  The Company will pay all costs and expenses in connection with
the transactions contemplated hereby, including, but not limited to, the fees
and disbursements of its counsel; the costs and expenses of printing (or
otherwise reproducing) and delivering the Pooling and Servicing Agreement and
the Offered Certificates; accounting fees and disbursements; the costs and
expenses in connection with the qualification or exemption of the 

                                      -7-

 
Offered Certificates under state securities or blue sky laws, including filing
fees and reasonable fees and disbursements of counsel in connection therewith,
in connection with the preparation of any Blue Sky Survey and in connection with
any determination of the eligibility of the Offered Certificates for investment
by institutional investors and the preparation of any Legal Investment Survey;
the expenses of printing any such Blue Sky Survey and Legal Investment Survey;
the costs and expenses in connection with the preparation, printing and filing
of the Registration Statement (including exhibits thereto), the Basic
Prospectus, the Preliminary Prospectus Supplement, if any, and the Prospectus
Supplement, the preparation and printing of this Agreement, the furnishing to
the Underwriters of such copies of each Preliminary Prospectus Supplement, if
any, and Prospectus Supplement as the Underwriters may reasonably request and
the fees of rating agencies. [Except as provided in Section 7 hereof,] the
Underwriters shall be responsible for paying all costs and expenses incurred by
them in connection with their purchase and sale of the Offered Certificates,
including the fees of counsel to any Underwriter.]

          6.  Conditions to the obligations to the Underwriters.  The
              -------------------------------------------------      
obligations of the Underwriters to purchase the Offered Certificates as provided
in this Agreement shall be subject to the accuracy of the representations and
warranties on the part of the Company contained herein as of the date hereof and
the Closing Date, to the accuracy of the statements of the Company made in any
certificates pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional conditions
with respect to the Offered Certificates:

          (a) No stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceedings for that purpose shall have
been instituted or threatened; and the Prospectus Supplement shall have been
filed with the Commission within the time period prescribed by the Commission.

          (b) The Company shall have delivered to you a certificate, dated the
Closing Date, of any of [list applicable executives] of the Company to the
effect that the signer of such certificate has carefully examined this Agreement
and the Prospectus and that: (i) the representations and warranties of the
Company in this Agreement are true and correct in all material respects at and
as of the Closing Date with the same effect as if made on the Closing Date, (ii)
the Company has complied with all the agreements and satisfied all the
conditions on its part to be performed or satisfied at or prior to the Closing
Date, (iii) no stop order suspending the effectiveness of the Registration
Statement has been issued and no proceedings for that purpose have been
instituted or, to the Company's knowledge, threatened, and (iv) nothing has come
to his attention that would lead him to believe that the Prospectus contains any
untrue statement of a material fact or omits to state any material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          (c) The Underwriters shall have received from [Cadwalader, Wickersham
& Taft], special counsel for the Company, a favorable opinion, dated the Closing
Date and satisfactory in form and substance to counsel for the Underwriters, to
the effect that:

                                      -8-

 
     (i)  Assuming due authorization, execution delivery by the company of this
          Agreement and the Pooling and Servicing Agreement, each of this
          Agreement and the Pooling and Servicing Agreement is a legal, valid
          and binding agreement of the Company enforceable against the Company
          in accordance with its terms;

    (ii)  The Offered Certificates, when duly executed, authenticated and
          delivered in accordance with the Pooling and Servicing Agreement, will
          be validly issued and outstanding and entitled to the benefits of such
          Pooling and Servicing Agreement;

   (iii)  The Pooling and Servicing Agreement is not required to be qualified
          under the Trust Indenture Act of 1939, as amended, and the trust
          created thereunder is not required to be registered under the
          Investment Company Act of 1940, as amended;

    (iv)  Such counsel confirms that [(based solely upon telephonic confirmation
          from a representative of the Commission)] the Registration Statement
          is effective under the Act and, to the best of such counsel's
          knowledge, no stop order with respect thereto has been issued, and no
          proceeding for that purpose has been instituted or threatened by the
          Commission under the Act; such Registration Statement (except the
          financial statements and schedules and other financial and statistical
          data included therein and the documents incorporated by reference
          therein, as to which such counsel need express no view), at the time
          it became effective and the Prospectus (except the financial
          statements and schedules and the other financial and statistical data
          included therein and the documents incorporated by reference therein
          as to which such counsel need express no view), as of the date of the
          Prospectus Supplement, appeared on their face to be appropriately
          responsive in all material respect to the requirements of the Act and
          the rules and regulations thereunder;

     (v)  The statements set forth in the Prospectus under the headings "Federal
          Income Tax Consequences" (insofar as they relate specifically to the
          purchase, ownership and disposition of the Offered Certificates) and
          "ERISA Considerations" (insofar as they relate specifically to the
          purchase, ownership and disposition of such Offered Certificates), to
          the extent that they constitute matters of law or legal conclusions,
          provide a fair summary of such law or conclusions; and

    (vi)  Assuming compliance with all provisions of the Pooling and Servicing
          Agreement, for federal income tax purposes, the Trust Fund (other than
          any such excluded assets) will qualify as one or more REMICs pursuant
          to Section 860D of the Internal Revenue Code of 1986, as amended (the
          "Code"), each Class of Certificates of the Series, other than the
           ----                                                            
          Residual Class or Classes, will constitute a class of "regular
          interests" in a REMIC within the meaning of the 

                                      -9-
       

 
          Code, and each Class of such Certificates specified in the Prospectus
          as a Class of Residual Certificates will constitute the "residual
          interest" in a REMIC within the meaning of the Code.

          Such opinion (a) may express its reliance as to factual matters on
certificates of government and agency officials and the representations and
warranties made by, and on certificates or other documents furnished by officers
of, the parties to this Agreement and the Pooling and Servicing Agreement, (b)
may assume the due authorization, execution and delivery of the instruments and
documents referred to therein by the parties thereto other than the Company, and
(c) may be qualified as an opinion only on the law of the State of New York, the
federal law of the United States of America and the General Corporation Law of
the State of Delaware.

          Based on such counsel's participation in conferences with officers and
other representatives of the Company, the Servicer, Underwriters' counsel,
representatives of the Trustee and the Underwriters at which the contents of the
Registration Statement and the Prospectus were discussed and, although such
counsel need not pass upon or assume responsibility for the actual accuracy,
completeness or fairness of the statements contained in the Registration
Statement or the Prospectus (except as stated in paragraph [(vii)] above) and
need not make an independent check or verification thereof for the purpose of
rendering this opinion, on the basis of the foregoing, such counsel shall also
confirm that nothing has come to the attention of such counsel that would lead
such counsel to believe that the Registration Statement (which for purposes of
such opinion shall not be deemed to include any exhibits filed therewith or
documents incorporated by reference therein), at the time it became effective,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading, or that the Prospectus, as of the date of the Prospectus
Supplement and at the Closing Date, contained or contains an untrue statement of
a material fact or omitted or omits to state a material fact necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading (other than financial statements, schedules and other
numerical, financial and statistical data and the documents incorporated therein
and the information included under the caption "Plan of Distribution" contained
in the Registration Statement, any amendment thereof and the Prospectus, as to
which such counsel need express no opinion).  Insofar as questions of
materiality are involved in the foregoing opinion, such counsel may as to
factual matters necessary to the determination of materiality rely upon
certificates and other information provided by officers and other
representatives to the Company and as to determinations of materiality, may seek
in the first instance and rely where such counsel concludes such reliance is
justifiable, on the view of officers and other representatives of the Company.

          (d) The Underwriters shall have received from
______________________________, special counsel for the Company, a favorable
opinion, dated the Closing Date and satisfactory in form and substance to
counsel for the Underwriters, to the effect that:

               (iii)  Neither the offer, sale and issuance of the Offered
     Certificates nor the consummation of any other of the transactions
     contemplated in this Agreement or the Pooling and Servicing Agreement will
     conflict with or result in a breach or violation of any term or provision
     of, or constitute a default (or an event which with the passing of time or
     notification, or both, would constitute a default), under the certificate
     of incorporation or by-laws of the Company or, to the knowledge of such
     counsel, any indenture or other agreement or instrument to which the
     Company is a party or by which it is bound, or any State of New York, State
     of Delaware or federal statute or regulation applicable to the Company or,
     to the knowledge of such counsel, any order of any State of New York, State
     of Delaware or federal court, regulatory body, administrative agency or
     governmental body having jurisdiction over the Company.

               (iv)   To the knowledge of such counsel, there are no material
     contracts, indentures or other documents of the Company required to be
     described or referred to in the Registration Statement or to be filed as

     counsel, threatened action, suit or proceeding before any court or
     governmental agency, authority or body or any arbitrator involving the
     Company of a character required to be disclosed in the Registration
     Statement which is not adequately disclosed in the Prospectus, and there is
     no franchise, contract or other document of a character required to be

     exhibit, which is not described or filed as required.

               (vi) No consent, approval, authorization or order of the State of
     New York, State of Delaware or any federal court or governmental agency or
     body is required for the consummation by the Company of the transactions by
     this Agreement and the Pooling and Servicing Agreement, except (i) such as
     have been obtained under the Act and (ii) such as may be required under the
     blue sky laws of any jurisdiction in 

                                      -11-

 
     connection with the purchase and the offer and sale of the Offered
     Certificates by any Underwriter, as to which such counsel need express no
     opinion.

          Such opinion (a) may express counsel's reliance as to factual matters
on certificates of government and agency officials and the representations and
warranties made by, and on certificates or other documents furnished by officers
of, the parties to this Agreement and the Pooling and Servicing Agreement and
(b) may be qualified as an opinion only on the law of the State of New York, the
General Corporate Law of the State of Delaware and the federal law of the United
States of America.

          (e) The Underwriters shall have received from counsel for the Servicer
a favorable opinion, dated the Closing Date and satisfactory in form and

     validly existing and in good standing under the laws of the State(s] of [or
     _____________________, as the case may be] and has corporate power and
     authority (corporate and other) to own its properties and conduct its
     business as described in the Prospectus, to enter into and perform its
     obligations under the Pooling and Servicing Agreement and to consummate the
     transactions contemplated thereby, is duly qualified as a foreign
     corporation in good standing in all jurisdictions in which the ownership or

     necessary to lease, own or license, as the case may be, and to operate, its
     properties and to carry on its business as described in the Prospectus, and
     is conducting its business so as to comply in all material respects with

     jurisdictions in which it is conducting business.

               (ii) The execution and delivery of the Pooling and Servicing
     Agreement has been duly authorized by the Servicer and the Pooling and
     Servicing Agreement has been duly executed and delivered by it and
     constitutes its valid and binding agreement, enforceable against it in
     accordance with its terms, except as such enforceability may be limited by
     bankruptcy, insolvency, liquidation, receivership, moratorium,
     reorganization or similar laws affecting the enforcement of rights of
     creditors generally and to general principles of equity regardless of
     whether enforcement is sought in a proceeding in equity or at law.

              (iii) Neither the execution nor the delivery of the Pooling and
     Servicing Agreement, nor the consummation of any other of the transactions
     contemplated therein, nor the fulfillment of the terms of the Pooling and
     Servicing Agreement will conflict with, result in a breach or violation of
     any term or provision of, or constitute a default (or an event which with
     the passage of time or notification, or both, would constitute a default)
     under the [certificate] [articles] of incorporation or by-laws of the
     Servicer, any statute currently applicable to it or any order, or

                                      -12-

 
     regulation currently applicable to it of any court, regulatory body,
     administrative agency or governmental body having jurisdiction over it or
     the terms of any indenture or other agreement or instrument known to such
     counsel to which it is a party or by which it or any of its properties are
     bound.

               (iv) There is no pending or, to the best knowledge of such
     counsel, threatened action, suit or proceeding before any court or
     governmental agency, authority or body or any arbitrator involving the
     Servicer of a character required to be disclosed in the Registration
     Statement which is not adequately disclosed in the Prospectus, and there is
     no franchise, contract or other document of a character required to be

     exhibit, which is not described or filed as required.

               (v)  No approval, authorization, consent or order, registration,

other documents furnished by officers of, the parties to this Agreement and the
Pooling and Servicing Agreement, (b) may assume the due authorization, execution
and delivery of the Pooling and Servicing Agreement and the instruments and
documents referred to therein by the parties thereto other than the Servicer and

____________________,  as the case may be,] and the federal law of the United

reasonably request and as are agreed to by ______________, compared the results
of their calculations to the corresponding items in the Prospectus, and found
each such number and percentage set forth in the Prospectus to be in agreement
with the results of such calculations].  To the extent historical financial
information with respect to the Company and/or historical financial, delinquency
or related information with respect to one or more servicers is included in the
Prospectus, such letter or letters shall also relate to such information.

          (h) The Offered Certificates listed on Schedule III hereto shall have

          If any of the conditions specified in this Section 6 shall not have

or if any of the opinions and certificates mentioned above or elsewhere in this
Agreement shall not be in all material respects reasonably satisfactory in form
and substances to the Underwriters and counsel for the Underwriters, this
Agreement and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date by the Underwriters.  Notice of such
cancellation shall be given to the Company in writing, or by telephone or by

          [7.  Reimbursement of Underwriters' Expenses.  If the sale of any
               ---------------------------------------                     
Offered Certificates provided for herein is not consummated because any
condition to the obligations of the Underwriters set forth in Section 6 hereof
is not satisfied or because of any refusal, inability or failure on the part of
the Company to perform any agreement herein or therein or comply with any
provision hereof or thereof, other than by reason of a default by any of the
Underwriters, the Company will reimburse the Underwriters severally upon demand
for all out-of-pocket expenses (including reasonable fees and disbursements of
counsel) that shall have been incurred by them in connection with the proposed
purchase and sale of such Offered Certificates.]

          8.  Indemnification and Contribution. (a) The Company agrees to
              --------------------------------                           
indemnify and hold harmless each Underwriter and each person who controls any
Underwriter within the meaning of the Act or the Exchange Act against claims,
damages, or liabilities, joint or several, to which such Underwriter may become
subject, under the Act, the Exchange Act or otherwise, insofar as such losses,
claims, damages, or liabilities (or actions in respect thereof) arise out of or
are based upon any untrue statement or alleged untrue statement of a material
fact contained in any part of the Registration Statement when such part became
effective, or in the Registration Statement, any Preliminary Prospectus
Supplement, the Prospectus, or any amendment or supplement thereto, or any
preliminary prospectus supplement, or arise out of or are based upon the
omission or alleged omission (in the case of any Computational Materials or ABS
Term Sheets (as defined in Section 9 below) in respect of which the Company
agrees to indemnify any Underwriter or any such controlling person, as set forth
below, where such are made in conjunction with the Prospectus) to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each Underwriter and each
such controlling person for any legal or other expenses reasonably incurred by
it in connection with investigating or defending against such loss, claim,
damage, liability, or action; provided, however, (i) that the Company shall not
be liable in any such case to the extent that any such loss, claim, damage, or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made therein (A) in reliance upon and
in conformity with written information 

                                      -14-

 
furnished to the Company by any Underwriter directly or through another
Underwriter specifically for use in the preparation thereof or (B) in any
Current Report or any amendment or supplement thereof, except to the extent that
any untrue statement or alleged untrue statement therein or omission therefrom
results (or is alleged to have resulted) directly from an error (a "Mortgage
                                                                    --------
Pool Error") in the information concerning the characteristics of the Mortgage
- ----------
Loans furnished by the Company to an Underwriter in writing or by electronic
transmission that was used in the preparation of either (x) any Computational
Materials or ABS Term Sheets (or amendments or supplements thereof) or (y) any
written or electronic materials furnished to prospective investors on which the
Computational Materials (or amendments or supplements) were based, (ii) such
indemnity with respect to any preliminary prospectus shall not inure to the
benefit of any Underwriter (or any person controlling any Underwriter) from whom
the person asserting any such loss claim, damage or liability purchased the
Offered Certificates which are the subject thereof if such person did not
receive a copy of the Prospectus (or the Prospectus as amended or supplemented)
at or prior to the confirmation of the sale of such Certificates to such person
in any case where such delivery is required by the Act and the untrue statement
or omission of a material fact contained in such preliminary prospectus was
corrected in the Prospectus (or the Prospectus as amended or supplemented) and
(iii) such indemnity with respect to any Mortgage Pool Error shall not inure to
the benefit of any Underwriter (or any person controlling any Underwriter) from
whom the person asserting any loss, claim, damage or liability received any
Computational Materials or ABS Term Sheets (or any written or electronic
materials on which the Computational Materials or ABS Term Sheets are based)
that were prepared on the basis of such Mortgage Pool Error, if, prior to the
time of confirmation of the sale of the applicable Offered Certificates to such
person, the Company notified such Underwriter in writing of the Mortgage Pool
Error or provided in written or electronic form information superseding or
correcting such Mortgage Pool Error (in any such case, a "Corrected Mortgage
                                                          ------------------
Pool Error"), and such Underwriter failed to notify such person thereof or to
- ----------
deliver to such person corrected Computational Materials (or underlying written
or electronic materials) or ABS Term Sheets. This indemnity agreement will be in
addition to any liability which the Company may otherwise have.

          (b) Each Underwriter agrees, severally and not jointly, to indemnify
and hold harmless the Company, each of its directors, each of its officers who
signs the Registration Statement, and each person who controls the Company
within the meaning of either the Act or the Exchange Act, to the same extent as
the foregoing indemnity from the Company to each Underwriter, but only with
reference to (A) written information relating to such Underwriter furnished to
the Company by an Underwriter directly or through another Underwriter
specifically for use in the preparation of the documents referred to in the
foregoing indemnity, or (B) any Computational Materials or ABS Term Sheets (or
amendments or supplements thereof) delivered to prospective investors by such
Underwriter and furnished to the Company by such Underwriter pursuant to or as
contemplated by Section 9 and incorporated by reference in the Registration
Statement or the Prospectus or any amendment or supplement thereof (except that
no such indemnity shall be available for any losses, claims, damages or
liabilities, or actions in respect thereof, resulting from any Mortgage Pool
Error, other than a Corrected Mortgage Pool Error).  This indemnity 

                                      -15-

 
agreement will be in addition to any liability which any Underwriter may
otherwise have. The Company acknowledges that [the statements set forth in the
last paragraph of the cover page and under the heading "Underwriting" or "Plan
of Distribution" in any Preliminary Prospectus Supplement or the Prospectus]
constitute the only information furnished in writing by or on behalf of the
several Underwriters for inclusion in the documents referred to in the foregoing
indemnity (other than any Computational Materials or ABS Term Sheets furnished
to the Company by any Underwriter, and you confirm that such statements are
correct. (Any Computational Materials or ABS Term Sheets (or amendments or
supplements thereof) furnished to the Company by a particular Underwriter shall
relate exclusively to and be the several responsibility of such Underwriter and
no other Underwriter.]

          (c) Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
this Section 8.  In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein, and to the extent
that it may elect by written notice delivered to the indemnified party promptly
after receiving the aforesaid notice from such indemnified party, to assume the
defense thereof, with counsel satisfactory to such indemnified party (which may
be counsel representing the indemnifying party); provided, however, that if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assert such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties.  Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party will not be liable to
such indemnified party under this Section 8 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed separate counsel in
connection with the assertion of legal defenses in accordance with the proviso
to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel, approved by the Underwriters in the case of paragraph (a) of
this Section 8, representing the indemnified parties under such paragraph (a)
who are parties to such action), (ii) the indemnifying party shall not have
employed counsel satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action or (iii) the indemnifying party has authorized the employment of counsel
for the indemnified party at the expense of the indemnifying party; and except
that, if clause (i) or (iii) is applicable, such liability shall be only in
respect of the counsel referred to in such clause (i) or (iii).

                                      -16-

 
          (d) If the indemnification provided for in this Section 8 is
unavailable or insufficient to hold harmless an indemnified party under
paragraph (a) or (b) above, then each indemnifying party shall contribute to the
amount paid or payable by such indemnified party as a result of the losses,
claims, damages, or liabilities referred to in paragraph (a) or (b) above as
follows:

          (i) in the case of any losses, claims, damages and liabilities (or
     actions in respect thereof) which do not arise out of or are not based upon
     any untrue statement or omission of a material fact in any Computational
     Materials or ABS Term Sheets (or any amendments or supplements thereof) in
     such proportion so that the Underwriters are responsible for that portion
     represented by the percentage that the underwriting discount bears to the
     sum of such discount and the purchase price of the Offered Certificates
     specified in Schedule I hereto and the Company is responsible for the
     balance; provided, however, that in no case shall any Underwriter (except
     as may be provided in any agreement among underwriters relating to the
     offering of the Offered Certificates) be responsible under this
     subparagraph (i) for any amount in excess of the underwriting discount
     applicable to the Offered Certificates purchased by such Underwriter
     hereunder; and

          (ii) in the case of any losses, claims, damages and liabilities (or
     actions in respect thereof) which arise out of or are based upon any untrue
     statement or omission of a material fact in any Computational Materials or
     ABS Terms Sheets (or any amendments or supplements thereof) or in any
     written or electronic materials on which the Computational Materials are
     based, in such proportion as is appropriate to reflect the relative fault
     of the Company on the one hand and the Underwriters on the other in
     connection with the statement or omissions which resulted in such losses,
     claims, damages or liabilities (or actions in respect thereof) as well as
     any other relevant equitable considerations.  The relative fault shall be
     determined by reference to, among other things, whether the untrue or
     alleged untrue statement of a material fact or the omission or alleged
     omission to state a material fact in such Computational Materials or ABS
     Term Sheets (or any amendments or supplements thereof or such written or
     electronic materials) results from information prepared by the Company on
     the one hand or Underwriters on the other and the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent such
     statement or omission.

          Notwithstanding anything to the contrary in this paragraph (d), no
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.  For purposes of this Section 8,
each person who controls an Underwriter within the meaning of the Act shall have
the same rights to contribution as such Underwriter, and each person who
controls the Company within the meaning of either the Act or the Exchange Act,
each officer of the Company who shall have signed the Registration Statement and
each director of the Company shall have the same rights to contribution as the
Company, subject in each case to the preceding sentence of this paragraph (d).
Any party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or 

                                      -17-

 
proceeding against such party in respect of which a claim for contribution may
be made against another party or parties under this paragraph (d), notify such
party or parties from whom contribution may be sought, but the omission to so
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any other obligation it or they may have
hereunder or otherwise than under this paragraph (d).

     Sheets comply with the requirements of the PSA Letter;

          (iv) on the date any such Computational Materials or Structural Term
     Sheets with respect to such Offered Certificates (or any written or
     electronic materials furnished to prospective investors on which the
     Computational Materials are based) were last furnished to each prospective
     investor by such Underwriter and on the date of delivery thereof to the
     Company pursuant to Section 9(a) and on the Closing Date, such
     Computational Materials (or such other materials) or Structural Term Sheets
     did not and will not include any untrue statement of a material fact or,
     when read in conjunction with the Prospectus and Prospectus Supplement,
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading; and

          (v) at the time any Computational Materials or Structural Term Sheets
     with respect to the Offered Certificates were furnished to a prospective
     investor and on the date hereof, the Underwriters possessed, and on the

     of internal control necessary to ensure that such Computational Materials
     or Structural Term Sheets conform to the representations and warranties of
     the Underwriters contained in subparagraphs (ii)-(iv) above of this
     paragraph (b);

          (vi) all Computational Materials (or underlying materials distributed

     page thereof, stating that the Computational Materials or Structural Term
     Sheets are being produced and provided exclusively by the Underwriter and
     that the Underwriter is acting as an underwriter and not acting as an agent
     of the Company in connection with the securities described herein, and
     otherwise in form and substance satisfactory to the Company.

                                      -19-

 
Notwithstanding the foregoing, each Underwriter makes no representation or
warranty as to whether any Computational Materials or Structural Term Sheets (or
any written or electronic materials on which the Computational Materials are
based) included or will include any untrue statement resulting directly from any
Mortgage Pool Error (except any Corrected Mortgage Pool Error, with respect to
materials prepared after the receipt by such Underwriter from the Company of
notice of such Corrected Mortgage Pool Error or materials superseding or
correcting such Corrected Mortgage Pool Error).

          (c) The Underwriters shall cause a firm of public accountants to
furnish to the Company a letter, dated as of the date on which the Underwriters
deliver any Computational Materials (which term shall be deemed to include, for
purposes of this paragraph (c), calculated statistical information delivered to
prospective investors in the form of a Structural Term Sheet) to the Company
pursuant to Section 9(a), in form and substance satisfactory to the Company,
stating in effect that they have verified the mathematical accuracy of any
calculations performed by each Underwriter and set forth in such Computational
Materials.

          (d) Each Underwriter acknowledges and agrees that the Company has not
authorized and will not authorize the distribution of any Computational
Materials (or any written or electronic materials on which the Computational
Materials are based) or Structural Term Sheets to any prospective investor, and
agrees that any Computational Materials or Structural Term Sheets with respect
to any Series of Certificates furnished to prospective investors shall include a
disclaimer in the form described in paragraph (b)(iv) above.

Each Underwriter agrees that it will not represent to prospective investors that
any Computational Materials or Structural Term Sheets were prepared or
disseminated on behalf of the Company.

          (e) If, at any time when a prospectus relating to the Offered
Certificates of a Series is required to be delivered under the Act, it shall be
necessary to amend or supplement the Prospectus as a result of an untrue
statement of a material fact contained in any Computational Materials or
Structural Term Sheets provided by any Underwriter pursuant to this Section 9 or
the omission to state therein a material fact required, when considered in
conjunction with the Prospectus and Prospectus Supplement, to be stated therein
or necessary to make the statements therein, when read in conjunction with the
Prospectus and Prospectus Supplement, not misleading, or if it shall be
necessary to amend or supplement any Current Report relating to any
Computational Materials or Structural Term Sheets to comply with the Act or the
rules thereunder, such Underwriter promptly will prepare and furnish to the
Company for filing with the Commission an amendment or supplement which will
correct such statement or omission or an amendment which will effect such
compliance.  Each Underwriter represents and warrants to the Company, as of the
date of delivery by it of such amendment or supplement to the Company, that such
amendment or supplement will not include any untrue statement of a material fact
or, when read in conjunction with the Prospectus and Prospectus Supplement, omit
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading; provided, however, that each such Underwriter
makes no 

                                      -20-

 
representation or warranty as to whether any such amendment or supplement will
include any untrue statement resulting directly from any Mortgage Pool Error
(except any Corrected Mortgage Pool Error, with respect to any such amendment or
supplement prepared after the receipt by such Underwriter from the Company of
notice of such Corrected Mortgage Pool Error or materials superseding or
correcting such Corrected Mortgage Pool Error). The Company shall have no
obligation to file such amendment or supplement if (i) the Company determines
that such amendment or supplement conjunction with the Prospectus and Prospectus
Supplement, omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; it being understood,
however, that the Company shall have no obligation to review or pass upon the
accuracy or adequacy of, or to correct, any such amendment or supplement
provided by any Underwriter to the Company pursuant to this paragraph (e) or
(ii) the Company reasonably determined that such filing is not required under
the Act and the Underwriters do not object as provided below. The Company shall
give notice to the Underwriters of its determination not to file an amendment or
supplement pursuant to clause (ii) of the preceding sentence and agrees to file
such amendment or supplement if the Underwriters reasonably object to such
determination within one business day after receipt of such notice.

          10.  Collateral Term Sheets. (a) Prior to the delivery of any
               ----------------------                                  
"Collateral Term Sheet" within the meaning of the PSA Letter, the filing of
which is a condition of the relief granted in such letter (such material being
the "Collateral Term Sheets"), to a prospective investor in the Offered
     ----------------------                                            
Certificates, the Underwriters shall notify the Company and its counsel by
telephone of their intention to deliver such materials and the approximate date
on which the first such delivery of such materials is expected to occur.  Not
later than 10:30 a.m., New York time, on the business day immediately following
the date on which any Collateral Term Sheet was first delivered to a prospective
investor in the Offered Certificates, the Underwriters shall deliver to the
Company five complete copies of all materials provide by the Underwriters to
prospective investors in such Offered Certificates which constitute "Collateral
Term Sheets."  Each delivery of a Collateral Term Sheet to the Company pursuant
to this paragraph (a) shall be effected by delivering four copies of such
materials to counsel for the Company on behalf of the Company at the address
specified in Section 14 hereof and one copy of such materials to the Company.
(Collateral Term Sheets and Structural Term Sheets are, together, referred to
herein as "ABS Term Sheets.")  At the time of each such delivery, the
           ---------------                                           
Underwriter making such delivery shall indicate in writing that the materials
being delivered constitute Collateral Term Sheets, and, if there has been any
prior such delivery shall indicate whether such materials differ in any material
respect from any Collateral Term Sheets previously delivered to the Company with
respect to such Series pursuant to this Section 10(a) as a result of the
occurrence of a material change in the characteristics of the Mortgage Loans.

          (b) Each Underwriter represents and warrants to and agrees with the
Company as of the date hereof and as of the Closing Date, that:

          (i) The Collateral Term Sheets furnished to the Company by such
     Underwriter pursuant to Section 10(a) constitute all of the materials
     furnished to prospective investors by such Underwriter prior to time of
     delivery thereof to the 

                                      -21-

 
     Company that are required to be filed with the Commission as "Collateral
     Term Sheets" with respect to the Offered Certificates in accordance with
     the PSA Letter, and such Collateral Term Sheets comply with the
     requirements of the PSA Letter;

          (ii) On the date any such Collateral Term Sheets with respect to such
     Offered Certificates were last furnished to each prospective investor by
     such Underwriter and on the date of delivery thereof to the Company
     pursuant to Section 10(a) and on the Closing Date, such Collateral Term
     Sheets did not and will not include any untrue statement of a material fact
     or, when read in conjunction with the Prospectus and Prospectus Supplement,
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading; and

          (iii)  such Underwriter has not represented to any prospective
     investor that any Collateral Term Sheets with respect to any Series were
     prepared or disseminated on behalf of the Company, and, except as otherwise
     disclosed by such Underwriter to the Company in writing prior to the date
     hereof, all Collateral Term Sheets previously furnished to prospective
     investors included a disclaimer to the effect set forth in Section 10(c).

Notwithstanding the foregoing, each Underwriter makes no representation or
warranty as to whether any Collateral Term Sheet included or will include any
untrue statement or material omission resulting directly from any Mortgage Pool
Error (except any Corrected Mortgage Pool Error, with respect to materials
prepared after the receipt by such Underwriter from the Company of notice of
such Corrected Mortgage Pool Error or materials superseding or correcting such
Corrected Mortgage Pool Error).

          (c) Each Underwriter acknowledges and agrees that any Collateral Term
Sheets with respect to any Series of Certificates furnished to prospective
investors from and after the date hereof shall include a disclaimer in form
satisfactory to the Company to the effect set forth in Section 9(d) hereof, and
to the effect that the information contained in such materials supersedes
information contained in any prior Collateral Term Sheet with respect to such
Series of Offered Certificates and will be superseded by the description of the
Mortgage Loans in the Prospectus Supplement and in the detailed description
relating to such Prospectus Supplement to be filed under cover of Form 8-K.
Each Underwriter agrees that it will not represent to prospective investors that
any Collateral Term Sheets were prepared or disseminated on behalf of the
Company.

          (d) If, at any time when a prospectus relating to the Offered
Certificates of a Series is required to be delivered under the Act, it shall be
necessary to amend or supplement the Prospectus as a result of an untrue
statement of a material fact contained in any Collateral Term Sheets provided by
any Underwriter pursuant to this Section 10 or the omission to state therein a
material fact required, when considered in conjunction with the Prospectus and
Prospectus Supplement, to be stated therein or necessary to make the statements
therein, when read in conjunction with the Prospectus and Prospectus Supplement,
not misleading, or if it shall be necessary to amend or supplement any Current
Report relating to any Collateral Term 

                                      -22-

 
Sheets to comply with the Act or the rules thereunder, such Underwriter promptly
will prepare and furnish to the Company for filing with the Commission an
amendment or supplement which will correct such statement or omission or an
amendment which will effect such compliance. Each Underwriter represents and
warrants to the Company, as of the date of delivery of such amendment or
supplement to the Company, that such amendment or supplement will not include
any untrue statement of a material fact or, when read in conjunction with the
Prospectus and Prospectus Supplement, omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading;
provided, however, each such Underwriter makes no representation or warranty as
to whether any such amendment or supplement will include any untrue statement
resulting directly from any Mortgage Pool Error (except any Corrected Mortgage
Pool Error, with respect to any such amendment or supplement prepared after the
receipt by such Underwriter from the Company of notice of such Corrected
Mortgage Pool Error or materials superseding or correcting such Corrected
Mortgage Pool Error). The Company shall have no obligation to file such
amendment or supplement if the Company determines that (i) such amendment or
supplement contains any untrue statement of a material fact or, when read in
conjunction with the Prospectus and Prospectus Supplement, omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; it being understood, however, that the Company shall
have no obligation to review or pass upon the accuracy or adequacy of, or to
correct, any such amendment or supplement provided by any Underwriter to the
Company pursuant to this paragraph (d) or (ii) such filing is not required under
the Act.

          11.  Substitution of Underwriters. (a) If any Underwriter shall fail
               ----------------------------                                   
to take up and pay for the amount of the Offered Certificates agreed by such
Underwriter to be purchased under this Agreement, upon tender of such Offered
Certificates in accordance with the terms hereof, and the amount of the Offered
Certificates not purchased does not aggregate more than 10% of the total amount
of the Offered Certificates set forth in Schedule I hereof, the remaining
Underwriters shall be obligated to take up and pay for the Offered Certificates
that the withdrawing or defaulting Underwriter agreed but failed to purchase.

          (b) If any Underwriter shall fail to take up and pay for the amount of
the Offered Certificates agreed by such Underwriter to be purchased under this
Agreement (such Underwriter being a "Defaulting Underwriter"), upon tender of
                                     ----------------------                  
such Certificates in accordance with the terms hereof and thereof, and the
amount of the Offered Certificates not purchased aggregates more than 10% of the
total amount of the Offered Certificates set forth in Schedule I hereto, and
arrangements satisfactory to the remaining Underwriters and the Company for the
purchase of such Certificates by other persons are not made within 36 hours
thereafter, this Agreement shall terminate.  In the event of any such
termination the Company shall not be under any liability to any Underwriter
(except to the extent provided in Section 5(f) and Section 8 hereof) nor shall
any Underwriter (other than an Underwriter who shall have failed, otherwise than
for some reason permitted under this Agreement, to purchase the amount of the
Offered Certificates such Underwriter agreed to purchase hereunder) be under any
liability to the Company (except to the extent provided in Sections 8, 9 and 10
hereof).  Nothing herein shall be deemed to relieve any Defaulting Underwriter
from any liability it 

                                      -23-

 
may have to the Company or any other Underwriter by reason of its failure to
take up and pay for Certificates as agreed by such Defaulting Underwriter.

          12.  Termination.  This Agreement shall be subject to termination in
               -----------                                                    
the absolute discretion of the Underwriters by notice given to the Company prior
to delivery of and payment for all Offered Certificates if prior to such time
[(i) trading in securities of the Company or any affiliate on the New York Stock
Exchange shall have been suspended or limited, or minimum prices shall have been
established on such Exchange, (ii) a banking moratorium shall have been declared
by either federal or New York State authorities,] or (iii) there shall have
occurred any outbreak or material escalation of hostilities or other calamity or
crisis, the effect of which on the financial markets of the United States is
such as to make it, in the reasonable judgment of the Underwriters, impractical
to market the Offered Certificates.

          13.  Representations and Indemnities to Survive.    The respective
               ------------------------------------------                   
agreements, representations, warranties, indemnities and other statements of the
Company or its officers and the Underwriters set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter or the Company or any of
the officers, directors or controlling persons referred to in Section 8 hereof,
and will survive delivery of and payment for the Offered Certificates.  The
provisions of Sections 7, 8, 9 and 10 hereof shall survive the termination or
cancellation of this Agreement.

          14.  Notices.  All communications hereunder will be in writing and
               -------

delivered or either telegraphed or transmitted by telecopier and confirmed to
them at the addresses set forth on Schedule I hereto; or, if sent to the Company
will be mailed, delivered or either telegraphed or transmitted by telecopier and

28210, with a copy to [                                 ].

          15.  Successors.  This Agreement will inure to the benefit of and be
               ----------                                                     
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 8 hereof, and their
successors and assigns, and no other person will have any right or obligation
hereunder.

          16.  Applicable Law; Counterparts.  This Agreement will be governed by
               ----------------------------                                     
and construed in accordance with the laws of the State of New York without
giving effect to the provisions thereof concerning conflict of laws.  This
Agreement may be executed in any number of counterparts, each of which shall for
all purposes be deemed to be an original and all of which shall together
constitute but one and the same instrument.

          17.  Performance under Pooling and Servicing Agreement.  You agree to
               -------------------------------------------------               
perform the obligations and exercise the rights of the Company, all on behalf of

agreement, please sign and return to us a counterpart hereof, whereupon this
letter and your acceptance shall represent a binding agreement among the Company
and the several Underwriters.
