the "Closing Date").  Delivery of the Offered Certificates shall be made to the
Underwriters against payment by the Underwriters of the purchase price thereof
to or upon the order of the Contract Seller in immediately available funds as
specified in Schedule II hereto.  The Offered Certificates to be so delivered
shall be in definitive, fully registered form, unless otherwise agreed, in such
denominations and registered in the name of Cede & Co., as nominee of The
Depository Trust Company, unless otherwise specified by the Contract Seller in
writing not less than three full business days in advance of the Closing Date.

     The Contract Seller agrees to have the Offered Certificates available for
inspection and checking by the Underwriters in New York, New York, not later
than

                                       5

1:00 p.m. on the business day prior to the Closing Date.

     Section 4.  Offering by Underwriters.  It is understood that the
                 ------------------------                            
Underwriters propose to offer the Offered Certificates for sale to the public as
set forth in the Prospectus.

     Section 5.  Agreements.  The Contract Seller agrees with the Underwriters
                 ----------                                                   
that:

          (a) It will prepare a supplement to the Base Prospectus setting forth
     the amount of Offered Certificates covered thereby and the terms thereof
     not otherwise specified in the Base Prospectus, the expected proceeds to
     the Contract Seller from the sale of such Offered Certificates, and such
     other information as the Underwriters and the Contract Seller may deem
     appropriate in connection with the offering of such Offered Certificates.
     It will promptly advise the Underwriters (i) when the Prospectus shall have
     been filed or transmitted to the Commission for filing pursuant to Rule
     424, (ii) when any amend ment to the Registration Statement shall have
     become effective, (iii) of any request by the Commission for any amendment
     to the Registration Statement or the Prospectus or for any additional
     information, (iv) when notice is received from the Commission that any
     post-effective amendment to the Registration Statement has become or will
     become effective, (v) of the issuance by the Commission of any stop order
     suspending the effectiveness of the Registration Statement or the
     institution or threatening of any proceeding for that purpose, (vi) of the
     receipt by the Contract Seller 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, and (vii) of the occurrence of any event that would cause the
     Registration Statement, as then in effect, to contain an untrue statement
     of a material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading.  The
     Contract Seller will not file any amendment to the Registration Statement
     or supplement to the Prospectus unless it has furnished you with 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, it will
     cause the Prospectus Supplement to be transmitted to the Commission for
     filing pursuant to Rule 424 under the Act by any means reasonably
     contemplated to result in compliance with said Rule.  It 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) 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

                                       6
<PAGE>
 
     untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein in 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, it will promptly 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, it
     will use its best efforts to cause such amendment of the Registration
     Statement to be made effective as soon as possible.

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

          (d) So long as the Offered Certificates shall be outstanding, the
     Contract Seller will cause the Servicer to deliver to the Underwriters the
     annual statement as to compliance and the annual statement of a firm of
     independent public accountants, furnished to the Trustee by the Servicer
     pursuant to Sections 4.20 and 4.21 of the Agreement, as soon as such
     statements are furnished to the Trustee.

          (e) It 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 it 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.

          (f) It 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 Agreement and the Offered
     Certificates; accounting fees and disbursements; the costs and expenses in
     connection with the qualification or exemption of the Offered Certificates
     under state securities or blue sky laws (including filing fees but not fees
     and disbursements of counsel in connection therewith) in connection with
     the preparation of any blue sky

                                       7
<PAGE>
 
     survey and in connection with any determination of the eligibility of the
     Offered Certificates for investment by institutional investors; the
     expenses of printing any such blue sky survey; the cost and expenses in
     connection with the preparation, printing and filing of the Registration
     Statement (including exhibits thereto), the Base Prospectus, any
     Preliminary Prospectus Supplement and the Prospectus Supplement, the
     preparation and printing of this Underwriting Agreement and the furnishing
     to the Underwriters of such copies of each Preliminary Prospectus
     Supplement 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.

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

          (a) The Registration Statement shall have become effective and no stop
     order suspending the effectiveness of the Registration Statement, as
     amended from time to time, shall have been issued and not withdrawn; no
     proceedings for that purpose shall have been instituted or, to the best
     knowledge of the Contract Seller, threatened; and the Prospectus
     Supplement shall have been filed or transmitted for filing with the
     Commission in accordance with Rule 424 under the Act.

          (b) The Contract Seller shall have delivered to you a certificate,
     dated the Closing Date, of any Vice President, Assistant Treasurer or any
     Assistant Secretary thereof to the effect that the signer of such
     certificate has carefully examined this Underwriting Agreement, the
     Registration Statement and the Prospectus and that: (i) the representations
     and warranties made by it in this Underwriting 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) it 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
     knowledge of such signer, threatened, and (iv) nothing has come to such
     signer's attention that would lead such signer 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

                                       8
<PAGE>
 
     which they were made, not misleading.

          (c) The Underwriters shall have received from Orrick, Herrington &
     Sutcliffe LLP, counsel for the Contract Seller, a favorable opinion, dated
     the Closing Date and satisfactory in form and substance to counsel for the
     Underwriters, to the effect that:


          (i)     The Registration Statement has become effective under the Act,
                  and, to such counsel's knowledge, no stop order suspending the
                  effectiveness of the Registration Statement has been issued
                  and not withdrawn, and no proceedings for that purpose have
                  been instituted or threatened under Section 8(d) of the Act.

          (ii)    There are no contracts or documents of the Contract Seller
                  which are required to be filed as exhibits to the Registration
                  Statement pursuant to the Act which have not been so filed or
                  incorporated by reference therein on or prior to the Effective
                  Date.

          (iii)   The conditions to the use by the Contract Seller of a
                  registration statement on Form S-3 have been satisfied with
                  respect to the Registration Statement and the Registration
                  Statement, as of the Effective Date, and the Prospectus, as of
                  the date of the Prospectus Supplement, other than any
                  financial or statistical information contained therein as to
                  which such counsel need express no opinion, complied as to
                  form in all material respects with the requirements of the Act
                  and the applicable rules and regulations thereunder.

          (iv)    The Agreement constitutes a valid, legal and binding agreement
                  of the Contract Seller, enforceable against the Contract
                  Seller in accordance with its terms, except as enforceability
                  may be limited by (i) bankruptcy, insolvency, liquidation,
                  receivership, moratorium, reorganization or other similar laws
                  affecting the rights of creditors, and (ii) general principles
                  of equity, whether enforcement is sought in a proceeding in
                  equity or at law. The Underwriting Agreement constitutes a
                  valid and binding agreement of the Contract Seller.

          (v)     The Offered Certificates have been duly authorized and
                  delivered by the Contract Seller and, assuming due
                  authentication by the Trustee in accordance with the terms of
                  the Agreement, when issued, paid for and delivered in
                  accordance

                                       9
<PAGE>
 
                  with the terms of this Underwriting Agreement and the
                  Agreement, will be duly and validly issued and outstanding and
                  entitled to the benefits of the Agreement.

          (vi)    The statements set forth in the Prospectus under the heading
                  "Description of the Certificates," insofar as such statements
                  purport to summarize certain provisions of the Offered
                  Certificates and the Agreement, are correct in all material
                  respects. The statements set forth in the Prospectus under the
                  headings "ERISA Considerations," "Certain Federal Income Tax
                  Consequences," "Tax-Exempt Investors," "Legal Investment" and
                  "Other Considerations," to the extent that they constitute
                  matters of federal law or legal conclusions with respect
                  thereto, are correct in all material respects.

          (vii)   Based solely on the representations and warranties of the
                  Contract Seller in the Agreement, each Class of Senior
                  Certificates and the Class M Certificates will be "mortgage
                  related securities," as defined in Section 3(a)(41) of the
                  Securities Exchange Act of 1934, as amended, so long as such
                  Certificates are rated in one of the two highest rating
                  categories by at least one nationally recognized statistical
                  rating organization.

          (viii)  The Agreement is not required to be qualified under the Trust
                  Indenture Act of 1939, as amended, and the Trust Fund created
                  by the Agreement is not required to be registered under the
                  Investment Company Act of 1940, as amended.

          (ix)    The issuance and sale of the Offered Certificates to the
                  Underwriters pursuant to this Underwriting Agreement, the
                  compliance by the Contract Seller with the other provisions of
                  this Underwriting Agreement and the Agreement, and the
                  consummation of the other transactions herein and therein
                  contemplated do not, under any statute, regulation or rule of
                  general applicability, require the consent, approval,
                  authorization, order, registration or qualification of or with
                  any court or governmental authority, except as may be required
                  under the Act or other federal or state securities laws, or
                  any filings of UCC financing statements in respect of the
                  assignment of the Contracts to the Trustee pursuant to the
                  Agreement that have not yet been completed and such other
                  approvals as have been obtained; and neither the sale of the
                  Contracts nor the execution and delivery of the Agreement, nor
                  the consummation of any other transactions contemplated
                  therein, nor the fulfillment of the terms of the Agreement
                  will conflict with or

                                       10
<PAGE>
 
                  violate any statute currently applicable to it, or to such
                  counsel's knowledge, any rule or regulation currently
                  applicable to it of any regulatory body, administrative agency
                  or governmental body having jurisdiction over it.

          (x)     Assuming compliance with all provisions of the Agreement,
                  under existing law, (a) the Trust Fund will be treated as a
                  "real estate mortgage investment conduit" (a "REMIC"), as
                  defined by Section 860D of the Internal Revenue Code of 1986
                  (the "Code"), (b) each Class of Senior Certificates, Class M
                  Certificates, Class B-1 Certificates and Class B-2
                  Certificates will be treated as (or will be comprised of)
                  "regular interests" in such REMIC, as the term "regular
                  interest" is defined in the Code, and (c) the Class R
                  Certificates will be treated as the sole class of "residual
                  interests" in the REMIC, as the term "residual interest" is
                  defined in the Code.  However, continuation of the status of
                  the Trust Fund as a REMIC may entail compliance with statutory
                  changes in the future and with regulations not yet issued.

          (xi)    The Class A-1 Certificates would qualify as "Eligible
                  Securities" under paragraph (a)(9) of Rule 2a-7 under the
                  Investment Company Act of 1940, as amended.

     In addition, Orrick, Herrington & Sutcliffe, LLP shall state that they have
participated in conferences with your representatives and with representatives
of the Contract Seller concerning the Registration Statement and the Prospectus
and have considered the matters required to be stated therein and the statements
contained therein, although such counsel need not independently verified the
accuracy, completeness or fairness of such statements.  Based upon and subject
to the foregoing, such counsel shall state that nothing has come to its
attention to cause it to believe that the Registration Statement (excluding any
exhibits filed therewith), as of the Effective Date, 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, that
the Prospectus, as of the date of the Prospectus Supplement and as of the
Closing Date, contained or contains an untrue statement of a material fact or
omitted or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading (it being understood that such counsel have
not been requested to and such counsel does not make any comment in this
paragraph with respect to the financial statements, schedules and other
financial and statistical information contained in the Registration Statement or
the Prospectus).

          (d) The Underwriters shall have received from Andrea B. Goldenberg,
     counsel for the Contract Seller, a favorable opinion, dated the Closing
     Date and

                                       11
<PAGE>
 
     satisfactory in form and substance to counsel for the Underwriters, to the
     effect that:

                  (i) BAFSB is duly organized and validly existing as a federal
          savings bank in good standing under the federal laws of the United
          States and has the requisite power and authority, corporate or other,
          to own its own properties and conduct its own business, as presently
          conducted by it, and to enter into and perform its obligations under
          the Agreement, this Underwriting Agreement and the Offered
          Certificates.

                  (ii) This Underwriting Agreement and the Agreement have been
          duly and validly authorized, executed and delivered by BAFSB.

                  (iii)  No consent, approval, authorization or order of the
          State of California or federal court or governmental agency or body is
          required for the consummation by BAFSB of the transactions
          contemplated by the terms of this Underwriting Agreement and the
          Agreement, except for those consents, approvals, authorizations or
          orders which previously have been obtained.

                  (iv) The consummation of the transactions contemplated by, and
          the performance by BAFSB of any other of the terms of, this
          Underwriting Agreement and the Agreement will not result in a breach
          of any term or provision of the charter or bylaws of BAFSB or any
          State of California or federal statute or regulation or conflict with,
          result in a breach, violation or acceleration of, or constitute a
          default under, the terms of any indenture or other material agreement
          or instrument to which BAFSB is a party or by which it is bound or any
          order or regulation of the State of California or federal court,
          regulatory body, administrative agency or governmental body having
          jurisdiction over BAFSB.

                  (v) To the best of such counsel's knowledge, there are no
          actions, proceedings or investigations pending or threatened before
          any court, administrative agency or other tribunal (a) asserting the
          invalidity of this Underwriting Agreement, the Agreement or the
          Offered Certificates, or (b) seeking to prevent the issuance of the
          Offered Certificates or the consummation of any of the transactions
          contemplated by this Underwriting Agreement or the Agreement, which
          might materially and adversely affect the performance by BAFSB of its
          obligations under, or the validity or enforceability of, this
          Underwriting Agreement or the Offered Certificates.

     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

                                       12
<PAGE>
 
Underwriting Agreement and the 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 Contract Seller), and (c) may be qualified
as an opinion only as to the laws to the State of California and the United
States of America.

          (e) The Underwriters shall have received from Orrick, Herrington &
     Sutcliffe LLP an opinion to the effect that to the extent that the transfer
     of the Contracts and the proceeds thereof by the Bank to the Trustee
     pursuant to the Agreement does not constitute an absolute assignment of
     such Contracts and the proceeds thereof, then the Agreement creates in
     favor of the Trustee a security interest in the Bank's rights in such
     Contracts and the proceeds thereof.  Such security interest will be
     perfected upon the due and proper filing of the Financing Statement with
     the California Secretary of State.  At the time of such perfection, such
     security interest will be of first priority.

          (f) The Underwriters shall have received from Orrick, Herrington &
     Sutcliffe LLP an opinion to the effect that should the FDIC be appointed as
     conservator or receiver for the Bank pursuant to Section 11(c) of the FDIA,
     and should the transfer of the Contracts and the proceeds thereof to the
     Trustee pursuant to the Agreement be characterized as a secured transaction
     rather than an absolute sale, then if the matter were properly briefed and
     presented, the court would hold that the security interest of the Trustee
     for the benefit of the holders of the Certificates under the Agreement in
     the Contracts and the proceeds thereof is enforceable against the Bank with
     respect to such Contracts and such proceeds (within the meaning of Section
     9-203 of the applicable Uniform Commercial 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 Underwriting Agreement and the Agreement,
     (b) may assume the due authorization, execution and delivery of the

     computations.

          State of Illinois and the laws of the United States, (b) is duly

                  (ii)   The Agreement has been duly authorized, executed and
          delivered by the Trustee in its individual capacity and the Agreement
          has been duly authorized, executed and delivered by the Trustee in its
          capacity as Trustee of BankAmerica Manufactured Housing Contract Trust
          III, Senior/Subordinate Pass-Through Certificates, Series 1997-2.

                  (iii)  The Agreement, assuming due authorization, execution
          and delivery of such document by all other parties thereto,
          constitutes a legal, valid and binding agreement of the Trustee,
          except as enforceability thereof may be limited by bankruptcy,
          insolvency, liquidation, reorganization, moratorium or other similar
          laws affecting the enforcement of rights of creditors against the
          Trustee generally, as such laws would apply in the event of
          bankruptcy, insolvency, liquidation or reorganization or any
          moratorium or similar occurrence affecting the Trustee, and the
          application of general principles of equity (regardless of whether
          such enforceability is considered in a proceeding in equity or at
          law).

                  (iv)   No consent, approval, authorization or order of any
          governmental agency or body is required for the Trustee's acceptance
          and execution of the trusts contemplated by the Agreement.

          Agreement, the consummation of any other transactions contemplated in
          the Agreement and the fulfillment of the terms of the Agreement do

          provision of, or constitute a default under any agreement or any
          statute or regulation governing the Trustee.

                  (vi)   Assuming due authorization, execution and delivery of
          the Agreement by the Contract Seller, the Servicer and the Trustee,
          and assuming the Trustee's receipt of the initial trust estate

          created and validly exists under the laws of the State of Illinois,
          the terms of which are set forth in the Agreement.

                  (vii)  The Certificates have been duly authenticated and
          delivered by the Trustee.

     Contract Seller's business, operations, financial condition, properties or
     assets since the date of its latest quarterly financial statement, which

     obligations under the Agreement.

          (n)   The Underwriters shall have received from Orrick, Herrington &
     Sutcliffe LLP, a letter to the effect that the Underwriters may rely upon
     the opinion rendered by Orrick, Herrington & Sutcliffe LLP to any Rating
     Agency that is not addressed to the Underwriters in connection with the
     transactions contemplated herein.

          (o)   All proceedings in connection with the transactions contemplated
     by this Underwriting Agreement, and all documents incident hereto and
     thereto, shall be satisfactory in form and substance to the Underwriters
     and counsel for the Underwriters, and the Underwriters and counsel for the
     Underwriters shall have received such information, certificates and
     documents as they may reasonably request.

     Section 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 Contract Seller 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 Contract Seller will reimburse the Underwriters severally upon
demand for all reasonable and documented 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.

     Section 8.  Indemnification and Contribution.
                 -------------------------------- 

          (a) The Contract Seller will indemnify and hold harmless each
Underwriter and its respective directors, officers, agents and employees against
claims, damages, or liabilities, joint or several, to which each such
Underwriter or director, officer, agent or employee thereof may become subject,
under the Act or otherwise, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in 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 arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and
will reimburse each Underwriter and their respective directors, officers, agents
and employees for any reasonable and documented legal or other expenses incurred
by such Underwriter or director, officer, agent or employee thereof, as
incurred, in connection with investigating or defending against such loss,
claim, damage, liability or action; provided, however, (i) that the Contract
                                    --------  -------                       
Seller 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 in
reliance upon and in conformity with written information

                                       16
<PAGE>
 
furnished to the Contract Seller by you, or by any Underwriter through you,
specifically for use therein, and (ii) such indemnity with respect to any
Preliminary Prospectus or Preliminary Prospectus Supplement 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 Offered 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 or Preliminary Prospectus Supplement was corrected in the Prospectus
(or the Prospectus as amended or supplemented).

          (b) Each Underwriter, severally but not jointly, will indemnify and
hold harmless the Contract Seller and its directors, officers, agents and
employees against any losses, claims, damages, or liabilities to which the
Contract Seller or director, officer, agent or employee thereof may become
subject, under the Act or otherwise, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
part of the Registration Statement when such part became effective, or in any
Preliminary Prospectus Supplement, the Prospectus, or any amendment or
supplement thereto or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made therein in reliance upon and
in conformity with written information furnished to the Contract Seller by you,
or by such Underwriter through you, specifically for use therein, and will
reimburse the Contract Seller and its respective directors, officers, agents and
employees for any reasonable and documented legal or other expense incurred by
the Contract Seller or director, officer, agent or employee thereof, as
incurred, in connection with investigating or defending against any such loss,
claim, damage, liability or action.

          Each Underwriter, severally but not jointly, shall indemnify and hold
harmless the Contract Seller and its respective directors, officers, agents and
employees against any and all losses, claims, damages or liabilities, joint or
several, to the extent that such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
of a material fact contained in any Collateral Term Sheet, Structural Term
Sheet or Computational Materials (or based on an omission to state any material
fact necessary to make any statement contained therein not misleading), when
read together with the Prospectus (assuming for this purpose that the Prospectus
does not omit to state any material fact necessary to make any statement
contained in the Prospectus not misleading), furnished by such Underwriter to
the Contract Seller specifically for inclusion in a current report on Form 8-K
to be filed by or on behalf of the Contract Seller on or about November __, 1997
and such Underwriter shall in each case reimburse the Contract Seller and its

                                       17
<PAGE>
 
respective directors, officers, agents and employees for any reasonable and
documented legal or other expenses incurred by them in connection with
investigating or defending any such loss, claim, damage, liability or action;
                                                                             
provided, however, that such Underwriter shall not be liable in any such case to
- --------  -------                                                               
the extent that any such untrue statement or alleged untrue statement or
omission or alleged omission was made in reliance upon and in conformity with
written information furnished by the Contract Seller to such Underwriter in
respect of the Contracts.  Such Underwriter's liability under this Section 8(b)
shall be in addition to any liability that such Underwriter may otherwise have
(arising from such statement or omission).  Such Underwriter confirms that the
Collateral Term Sheets, Structural Term Sheets and Computational Materials so
furnished to the Contract Seller constitute all the Collateral Term Sheets,
Structural Term Sheets and Computational Materials furnished by such Underwriter
to prospective purchasers of the Offered Certificates.  Computational Materials
are computer-generated tables and/or charts displaying, with respect to any
class or classes of Certificates, any of the following: yield; average life;
duration; expected maturity; interest rate sensitivity; loss sensitivity; cash
flow characteristics; background information regarding the Contracts; the
proposed structure; decrement tables; or similar information (tabular or
otherwise) of a statistical, mathematical, tabular or computational nature.  The
terms "Collateral Term Sheet" and "Structural Term Sheet" shall have the
respective meanings assigned to them in the February 13, 1995 letter of Cleary,
Gottlieb, Steen & Hamilton on behalf of the Public Securities Association (which
letter, and the SEC staff's response thereto, were publicly available February
17, 1995).  The term "Collateral Term Sheet," as used herein, shall also include
any subsequent collateral term sheet that reflects a substantive change in the
information presented.

          (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 to so 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 except to the extent that the failure of the indemnified party to
notify the indemnifying party prejudices the rights of the indemnifying party.
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

                                       18
<PAGE>
 
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 (in addition to local counsel), approved by the
Underwriters in the case of Subsection (a) of this Section 8, representing the
indemnified parties under such Subsection (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).  In the event a party settles any claim or action
for which it would otherwise be indemnified against pursuant to Section 8
without the consent of the indemnifying party, such indemnified party shall
waive any rights to indemnification hereunder in connection with such claim or
action; provided, however, the indemnified party may settle such claim or action
without the consent of the indemnifying party and without waiving its rights to
indemnification if the indemnified party acts in accordance with the advice of
separate counsel engaged in accordance with this Subsection (c).

          (d) If the indemnification provided for in this Section 8 is
unavailable or insufficient to hold harmless an indemnified party under
Subsection (a) or (b) above, then the Contract Seller and each indemnifying
Underwriter 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
Subsection (a) or (b) above, (i) in such proportion as is appropriate to reflect
the relative benefits received by the Contract Seller on the one hand and the
Underwriters on the other from the offering of the Offered Certificates, or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above, but also the relative fault
of the Contract Seller on the one hand and the Underwriters on the other in
connection with the statement or omissions that resulted in such losses,
claims, damages, or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Contract Seller on the
one hand and the Underwriters on the other shall be deemed to be in the same
proportion as the total proceeds from the offering of the Offered Certificates
(before deducting expenses) received by the Contract Seller bear to the total
compensation and profit (before deducting expenses) received or realized by the
Underwriters from the purchase and resale, or underwriting, of the Offered
Certificates.  The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged

                                       19
<PAGE>
 
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Contract Seller, on the
one hand, or the Underwriters, on the other, and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
untrue statement or omission.  The Contract Seller, on the one hand, and the
Underwriters, on the other, agree that it would not be just and equitable if
contributions pursuant to this Subsection (d) were to be determined by pro rata
                                                                       --- ----
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account the
equitable considerations referred to in the first sentence of this Subsection
(d).  The amount paid by an indemnified party as a result of the losses, claims,
damages, or liabilities referred to in the first sentence of this Subsection (d)
shall be deemed to include any reasonable and documented legal or other expense
incurred by such indemnified party in connection with investigating or defending
against any action or claim which is the subject of this Subsection (d).
Notwithstanding the provisions of this Subsection (d), no Underwriter shall be
required to contribute any amount in excess of the amount by which (x) the total
price at which the Offered Certificates underwritten by it and distributed to
the public were offered to the public exceeds (y) the amount of any damages that
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Underwriters' obligations in this Subsection
(d) to contribute shall be several in proportion to their respective
underwriting obligations and not joint; provided that in the case of the
indemnification provided in the second paragraph of Subsection (b), only the
Underwriter furnishing the Collateral Term Sheets, Structural Term Sheets or
Computational Materials, as the case may be, that are the subject of such
indemnification shall contribute in respect thereof pursuant to this Subsection
(d).

          (e)    The obligations of the Contract Seller under this Section 8
shall be in addition to any liability which the Contract Seller may otherwise
have and shall extend, upon the same terms and conditions, to each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act; and the obligations of the Underwriters under this Section 8 shall be in
addition to any liability that the respective Underwriters may otherwise have
and shall extend, upon the same terms and conditions, to each director of the
Contract Seller (including any person who, with his consent, is named in the
Registration Statement as about to become a director of the Contract Seller), to
each officer of the Contract Seller who has signed the Registration Statement
and to each person, if any, who controls the Contract Seller within the meaning
of the Act or the Exchange Act.

     Section 9.  Substitution of Underwriters.  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 Underwriting Agreement upon tender of
such Offered Certificates in accordance with the terms hereof, and the amount
of the Offered Certificates

                                       20
<PAGE>
 
not purchased does not aggregate more than 10% of the total amount of the
Offered Certificates set forth in Schedule I hereto, 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.

     This Underwriting Agreement shall terminate if (i) 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 Underwriting Agreement (such
Underwriter being a "Defaulting Underwriter") upon tender of such Offered
Certificates in accordance with the terms hereof, (ii) 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 (iii) arrangements
satisfactory to the remaining Underwriters and the Contract Seller for the
purchase of such Offered Certificates by other persons are not made within 36
hours thereafter.  In the event of any such termination, the Contract Seller
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 Underwriting Agreement, to purchase the amount of the
Offered Certificates which such Underwriter agreed to purchase hereunder) be
under any liability to the Contract Seller (except to the extent provided in
Section 8 hereof).  Nothing herein shall be deemed to relieve any Defaulting
Underwriter from any liability it may have to the Contract Seller or any other
Underwriter by reason of its failure to take up and pay for Offered Certificates
as agreed to by such Defaulting Underwriter.

     Section 10.  Termination.  Notwithstanding anything herein contained, this
                  -----------                                                  
Underwriting Agreement may be terminated in the absolute discretion of the
Underwriters, by written notice given to the Contract Seller, if after the
execution of this Underwriting Agreement and prior to the delivery and payment
for all Offered Certificates (i) there has occurred any material adverse change
in the condition (financial or otherwise), earnings, business or properties of
the Contract Seller or BankAmerica Corporation, and their respective
subsidiaries, taken as a whole, the effect of which in the reasonable judgment
of the Underwriters materially impairs the investment quality of the Offered
Certificates; (ii) trading generally shall have been suspended or materially
limited on or by the New York Stock Exchange; (iii) a general moratorium on
commercial banking activities in New York shall have been declared by either
Federal or New York State authorities; or (iv) there shall have occurred any
outbreak or material escalation of hostilities in which the United States is
involved, and declaration of war by Congress or any other substantial national
or international calamity or emergency if, in the reasonable judgment of the
Underwriters, the effect of any such outbreak, escalation, declaration, calamity
or emergency makes it impracticable to proceed with completion of the sale and
payment for the Offered Certificates on the terms specified in this Underwriting
Agreement and the Prospectus Supplement.

     Section 11.  Representations and Indemnities to Survive.  The respective

Contract Seller or its officers and the Underwriters set forth in or made
pursuant to this Underwriting Agreement will remain in full force and effect,
regardless of any investigation made by or on behalf of any Underwriter, the
Contract Seller 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 Section 7 and 8 hereof shall
survive the termination or cancellation of this Underwriting Agreement.

     Section 12.  Notices.  All communications hereunder will be in writing and

            CONVEYANCE OF CONTRACTS; REPRESENTATIONS AND WARRANTIES

Section 2.01.  Conveyance of Contracts.
               -----------------------     

     (a)  The Contract Seller, concurrently with the execution and delivery
hereof, does hereby transfer, sell, assign, set over and otherwise convey to the
Trustee without recourse (i) all of the right, title and interest of the
Contract Seller in and to the Contracts listed in the Contract Schedule, as
amended from time to time, (including the security interests created thereby),
including all principal of and interest due on or with respect to the Contracts
on or after the Cut-off Date (other than payments of principal and interest due
on the Contracts before the Cut-off Date), (ii) all of the rights under all
Hazard Insurance Policies relating to the Manufactured Homes securing the
Contracts for the benefit of the creditors under such Contracts, (iii) all
documents contained in the Contract Files and in the Land Home Contract Files,
and (iv) all proceeds of any of the foregoing.

     The ownership of each Contract and the contents of the related Contract
File or Land Home Contract File, as applicable, and Servicing File are vested in
the Trustee.  The Servicer hereby disclaims any and all right, title and other
ownership interest in and to the Contracts (including the security interests
created thereby).  The contents of each Contract File and, except as provided in
Section 4.16(e), the contents of each Land Home Contract File, as applicable,
and Servicing File are and shall be held by the Servicer for the benefit of the
Trustee as the owner thereof (it being understood that the Servicer's possession
of the contents of each Contract File or Land Home Contract File, as applicable,
and Servicing File so retained is for the sole purpose of servicing the related
Contract, and such retention and possession by the Servicer is in a custodial
capacity only).  Neither the Contract Seller nor the Servicer shall take any
action inconsistent with the Trustee's ownership of the Contracts, and the
Contract Seller and the Servicer shall promptly indicate to all inquiring
parties that the Contracts have been sold, transferred, assigned, set over and
conveyed to the Trustee and shall not claim any ownership interest in the
Contracts.

     (b)  Although the parties intend that the conveyance of the Contract
Seller's right, title and interest in and to the Contracts pursuant to this
Agreement shall constitute a purchase and sale and not a loan, if such
conveyances are deemed to be a loan, the parties intend that the rights and
obligations of the parties to such loan shall be established pursuant to the
terms of this Agreement.  The parties also intend and agree that the Contract
Seller shall be deemed to have granted to the Trustee, and the Contract Seller
does hereby grant to the Trustee, a perfected first-priority security interest
in (i) all of its right, title and interest, whether now owned or hereafter
acquired, in and to the Contracts listed in the Contract Schedule, as amended
from time to time (including the security interests created thereby), including
all principal of and interest due on or with respect to the Contracts on or
after the Cut-Off Date (other than payments of principal and interest due on the
Contracts before the Cut-Off Date), (ii) all of the rights under all Hazard
Insurance Policies relating to the Manufactured Homes securing the Contracts for
the benefit of the creditors under such Contracts, (iii) all documents contained
in the Contract Files and in the Land Home Contract Files, and (iv) all proceeds
of any of the foregoing.  The parties intend and agree that this Agreement shall
constitute a security agreement under applicable law.  If the trust

                                      -31-
<PAGE>
 
created by this Agreement terminates prior to the satisfaction of the claims of
any Person under any Certificates, the security interest created hereby shall
continue in full force and effect and the Trustee shall be deemed to be the
collateral agent for the benefit of such Person.

Section 2.02.  Filing and Assignment; Name Change or Relocation.
               ------------------------------------------------     

     (a)  On or prior to the Closing Date, the Servicer shall cause to be filed

Contract Seller as debtor and the Trustee as secured party.

     From time to time, the Servicer shall take and cause to be taken such
actions and execute such documents as are necessary to perfect and protect the
Certificateholders' interests in the Contracts and their proceeds and the
Manufactured Homes and the Mortgaged Properties against all other Persons,
including the filing of financing statements, amendments thereto and
continuation statements, the execution of transfer instruments and the making of
notations on or taking possession of all records or documents of title;
provided, however, that BAFSB, so long as it is the Servicer, shall not be
- --------  -------                                                         
required to cause notations to be made on any document of title relating to any
Manufactured Home or to execute any transfer instrument relating to any
Manufactured Home (other than a notation or a transfer instrument necessary to
show the Contract Seller as the lienholder or legal title holder) or, except as
provided in Section 4.22, to file documents in real property records with
respect to a Manufactured Home or related Contract, absent notice from the
Trustee or the Contract Seller or actual knowledge that such Manufactured Home
that does not secure a Land Home Contract has become real property under
applicable state law; and further provided, that the Servicer shall have no
                          ------- --------                                 
obligation pursuant to this sentence with respect to any failure to maintain a
first-priority perfected security interest which results from a breach of any
representation or warranty in Section 3.02(j) or (u) as to the Trustee's
security interest in a Manufactured Home, except to enforce the Contract
Seller's obligations in respect thereof in Section 3.05.  The Trustee and the
Contract Seller agree to take whatever action is necessary to enable the
Servicer to fulfill its obligations as set forth in this Section 2.02(a).

     (b)  The Servicer agrees to pay all reasonable costs and disbursements in

and declares that the Trustee, directly or through a custodian (which shall be
the Servicer pursuant to Section 4.16, except as provided under Section
4.16(e)), holds and will hold such Contract Files in trust for the use and
benefit of all present and future Certificateholders.  The Trustee hereby
certifies (without any independent investigation) that it has no notice or
knowledge of (i) any adverse claim, lien or encumbrance with respect to any
Contract, (ii) any Contract being overdue or dishonored, (iii) any evidence on
the face of any Contract of any security interest therein adverse to the
Trustee's interest, or (iv) any defense against or claim against any Contract by
the Obligor or by any other party.  Nothing in this Agreement shall be construed
to constitute

                                      -32-
<PAGE>
 
acceptance by the Trustee or the Trust Fund of any liability or obligation of

     Notwithstanding anything in this Agreement to the contrary, the Servicer
shall deposit into the Certificate Account all amounts in respect of the

breach does not materially adversely affect the interests of the Trust Fund or
the interests of the Certificateholders therein.

to authorize the execution, delivery and performance of this Agreement.  When

          -----------                                                          
setoff, counterclaim or defense, including the defense of usury, and the
operation of any of the terms of the Contract or the exercise of any right
thereunder will not render the Contract unenforceable in whole or in part or

such Contract from the Contract Seller to the Trust Fund under this Agreement
unlawful.

     (h)  Compliance with Law.  All requirements of any federal, state or local
          -------------------

thereof, in the Manufactured Home covered thereby; such security interest has
been assigned by the Contract Seller as secured lender to the Trustee in

Services and (c) other matters to which like properties are commonly subject

Seller to the Trust Fund, it had good and marketable title

                                      -38-

default, breach, violation or event permitting acceleration.

     (n)  No Liens.  As of the Closing Date, there are, to its knowledge, no

          ------------------                                             
provides for level monthly payments of principal and interest which fully

          --------------

correct.

     (r)  One Original.  There is only one original executed Contract.  Such
          ------------                                                      
original Contract is in the custody of the Servicer on the Closing Date.

Contract, the related Manufactured Home is personal property and is not
considered or classified as part of the real estate on which it is located under
the laws of the jurisdiction in which it is located and was personal property
and was not considered or classified as part of the real estate on which it was

or permitted to perfect such security interest, the title document shows, or, if
a new or replacement title document with respect to such Manufactured Home is

will show, the Contract Seller as the holder of a first-priority security
interest in such Manufactured Home. If the related Manufactured Home is located
in a state in which the filing of a financing statement or the making of a
fixture filing under the UCC is required to perfect a security interest in
manufactured housing, such filings have been duly made and show the Contract
Seller as the secured party. If the related Manufactured Home secures a Land
Home Contract, such Manufactured Home is subject to a Mortgage properly filed in
the appropriate public recording office or such Mortgage will be properly filed
in the appropriate public recording office within 180 days, naming the Contract
Seller as mortgagee. In either case, the Trustee has the same rights as the
secured party of record would have (if such secured party were still the owner
of the Contract) against all Persons (including the Contract Seller and any
trustee in bankruptcy of the applicable Contract Seller) claiming an interest in
such Manufactured Home. Assuming consummation of the transactions contemplated
herein the Trustee has the same rights as the secured party of record would have
(if such secured party were still the owner of the Contract) against all Persons
claiming an interest in such Manufactured Home and, if applicable, such
Mortgaged Property.

     (w)  Qualified Mortgage for REMIC.  Each Contract is secured by a "single
          ----------------------------                                        
family residence" within the meaning of Section 25(e)(10) of the Code.  The fair
market value of the Manufactured Home securing each Contract was at least equal
to 80% of the adjusted issue price of the Contract at either (i) the time the
Contract was originated (determined pursuant to the REMIC Provisions) or (ii)

secured, or intended to be secured, in whole or in part by the lien of a
mortgage or deed of trust creating a first lien or an estate in fee simple in
the real property.

     (aa)  Financing of Real Property.  No Contract other than a Land Home

Contracts in the aggregate and not to any particular Contract, the Contract
Seller may select Contracts to repurchase or substitute for such that, had such
Contracts not been included as part of the Contract Pool and after giving effect
to such substitution, if any, there would have been no breach of such
representation or warranty; and further provided, that in connection with any
                                ------- --------                             
Contract that the Contract Seller is required to repurchase, the Contract Seller
shall at its own expense deliver to the Trustee an opinion of counsel to the
effect that the repurchase of such Contract will not cause the Trust Fund to
fail to qualify as a REMIC at any time any Certificate is outstanding under then
applicable REMIC Provisions, be deemed a contribution to the Trust Fund after
the Startup Day or cause any "prohibited transaction," in each case, that will
result in the

                                      -42-
<PAGE>
 
imposition of a tax under the applicable REMIC Provisions. It is understood and
agreed that the obligation of the Contract Seller to repurchase or substitute
for any Contract sold by it as to which a breach of a representation or warranty
set forth in Section 3.02 or 3.03 of this Agreement has occurred and is
continuing shall constitute the sole remedy respecting such breach available
to the Certificateholders, the Trust Fund or the Trustee; provided, however,
                                                                    ------- 
that the Contract Seller shall defend and indemnify the Trustee, the Certificate
Administrator, the Trust Fund and the Certificateholders against all costs,
expenses, losses, damages, claims and liabilities, including reasonable fees and
expenses of counsel, which may be asserted against or suffered by any of them as
a result of third-party claims arising out of any breach of a representation or
warranty set forth in Section 3.02(c), (d), (g), (h) or (w) of this Agreement.
Notwithstanding any other provision of this Agreement, the obligation of the
Contract Seller under this Section 3.05 shall not terminate upon an Event of
Default.

          Notwithstanding any other provision of this Agreement to the contrary,
any amount received on or recovered with respect to repurchased Contracts or
Replaced Contracts during or after the month of repurchase shall be the property
of the Contract Seller and need not be deposited in the Certificate Account.

          Notwithstanding the foregoing, the Contract Seller shall not deposit
cash into the Certificate Account pursuant to this Section 3.05 after the three-
month period beginning on the Closing Date unless it shall first have obtained
an Opinion of Counsel to the effect that such deposit will not give rise to any
tax under Section 86OF(a) (1) of the Code or Section 86OG(d) of the Code.  Any
such deposit shall not be invested.

          The Trustee shall have no obligation to pay any taxes pursuant to this
Section 3.05, other than from moneys provided to it by the Contract Seller or
from moneys held therefor pursuant to Section 4.17.  The Trustee shall be deemed
conclusively to have complied with this Section 3.05 if it follows the
directions of the Servicer required to be provided in the preceding paragraph.
Upon the repurchase of any Contract by the Contract Seller, the Trustee shall
delete such Contract from the Contract Schedule.

          For reasons of administrative convenience in servicing of the
Contracts, notwithstanding the above provisions of this Section 3.05(a), the
Contract Seller shall not be required to repurchase or substitute for any
Contract relating to a Manufactured Home located in any jurisdiction on account
of a breach of the representation or warranty contained in Section 3.02(j) or
(u) of this Agreement solely on the basis of failure by the Contract Seller to
cause notations to be made on any document of title relating to any such
Manufactured Home or to execute any transfer instrument (including any UCC-3
assignments) relating to any such Manufactured Home (other than a notation or a
transfer instrument necessary to show the Contract Seller as lienholder or legal
title holder) unless (i) a court of competent jurisdiction has adjudged that,
because of such failure, the Trustee does not have a perfected first-priority
security interest in such related Manufactured Home, or (ii) (A) the Servicer
has received written advice of counsel to the effect that a court of competent
jurisdiction has held that, solely because of a substantially similar failure on
the part of a pledgor or assignor of manufactured housing contracts (who has
perfected the assignment or pledge of such contracts), a perfected first-
priority security interest was not created in favor of the pledgee or assignee
(as the case may be) in a related

                                      -43-
<PAGE>
 
manufactured home which is located in such jurisdiction and which is subject to
the same laws regarding the perfection of security interests therein as apply to
Manufactured Homes located in such jurisdiction, and (B) the Servicer shall not
have completed all appropriate remedial action with respect to such Manufactured
Home within 90 days after receipt of such written advice. Any such advice shall
be from counsel selected by the Servicer on a nondiscriminatory basis from among
the counsel used by the Servicer in its general business in the jurisdiction in
question. The Servicer shall have no obligation on an ongoing basis to seek any
advice with respect to the matters described in clause (ii) above. However, the
Servicer shall seek advice with respect to such matters whenever information
comes to the attention of its general counsel which causes such general counsel
to determine that a holding of the type described in clause (ii)(A) might exist.
If any counsel selected by the Servicer informs the Servicer that no holding of
the type described in clause (ii)(A) exists, such advice shall be conclusive and
binding on the parties with respect to the applicable date and jurisdiction.

     (b)  On or prior to the date that is the second anniversary of the Closing
Date, the Contract Seller, at its election, may substitute a Contract for any
Contract that it is otherwise obligated to repurchase pursuant to Section
3.05(a) (such Contract being referred to as the "Replaced Contract") upon
satisfaction of the following conditions:

          (i)  the Contract to be substituted for the Replaced Contract is an
     Eligible Substitute Contract and the Contract Seller delivers an Officer's
     Certificate, substantially in the form of Exhibit E, to the Trustee
                                               ---------                
     certifying that such Contract is an Eligible Substitute Contract,
     describing in reasonable detail how such Contract satisfies the definition
     of the term "Eligible Substitute Contract" (as to satisfaction of
     representations and warranties, such description shall be that such
     Contract satisfies such representations and warranties) and certifying that
     the Contract File or the Land Home Contract File, as applicable, for such
     Contract is in the possession of the Servicer;

          (ii)  the Contract Seller shall have delivered to the Trustee evidence
     of filing with the appropriate office in California of a UCC-1 financing
     statement executed by the Contract Seller as debtor and naming the Trustee
     as secured party and listing such Contract as collateral;

          (iii)  the Contract Seller shall have delivered to the Trustee an
     Opinion of Counsel (a) to the effect that the substitution of such Contract
     for such Replaced Contract will not cause the Trust Fund to fail to qualify
     as a REMIC at any time any Certificate is outstanding under then applicable
     REMIC Provisions, be deemed a contribution to the Trust Fund after the
     Startup Day or cause any "prohibited transaction," in each case, that will
     result in the imposition of a tax under the applicable REMIC Provisions,
     and (b) to the effect that, except as to Contracts that are Land Home
     Contracts, no filing or other action other than the filing of financing
     statements on Form UCC-1 with the Secretary of State of the State of
     California, naming the Contract Seller as debtor and the Trustee as secured
     party as required by Section 3.05(a) of this Agreement and the filing of
     continuation statements as required by Section 2.02(a) is necessary to
     perfect as against third parties the conveyance of the substitute Contract
     by the Contract Seller to the Trustee; and

                                      -44-
<PAGE>
 
          (iv)  if the Scheduled Principal Balance of such Replaced Contract is
     greater than the Scheduled Principal Balance of such Contract, the Contract
     Seller shall have deposited in the Certificate Account the amount of such
     excess (which amount shall be deemed a Principal Prepayment on such
     Contract) and shall have included in the Officer's Certificate required by
     clause (i) above a certification that such deposit has been made.

          Upon satisfaction of such conditions, the Trustee shall add such
Contract to, and delete such Replaced Contract from, the Contract Schedule (or
cause such addition and deletion to be accomplished).  Such substitution shall
be effected prior to the first Determination Date that occurs more than 90 days
after the Contract Seller becomes aware or receives written notice from the
Servicer or the Trustee, of the breach referred to in Section 3.05(a).

     (c)  Promptly after the repurchase referred to in Section 3.05(a) or the
substitution referred to in Section 3.05(b), the Trustee shall execute such
documents as are presented to it by the Contract Seller and are reasonably
necessary to reconvey the repurchased Contract or Replaced Contract, as the case
may be, to the Contract Seller.

     (d)  Notwithstanding anything in this Section 3.05 to the contrary, in the
event any Opinion of Counsel referred to in this Section 3.05 indicates that a
repurchase or substitution, as the case may be, of a Contract will result in the
imposition of a tax under the applicable REMIC Provisions with respect to
"prohibited transactions," or deemed a contribution to the REMIC after the
"start-up day," the Contract Seller shall not be required to repurchase or
substitute the Contract to which such Opinion of Counsel relates unless and
until the Servicer has determined there is an actual or imminent default with
respect thereto or that the defect or breach giving rise to the repurchase or
substitution obligation adversely affects the enforceability of such Contract.

Section 3.06.  General.
               -------     

     (a)  It is understood and agreed that the representations and warranties in
this Article III hereof shall remain operative and in full force and effect,
shall survive the transfer and conveyance of the Contracts by the Contract
Seller to the Trustee and shall inure to the benefit of the Trustee.

     (b)  Any cause of action against the Contract Seller relating to or arising
out of the breach of any of its respective representations and warranties made
in this Article III shall accrue as to any Contract upon (i) discovery of such
breach by the Contract Seller or notice thereof by the Trustee or Servicer to
the Contract Seller, (ii) failure by the Contract Seller to cure such breach,
and (iii) demand upon the Contract Seller by the Trustee for all amounts payable
in respect of such Contract under this Agreement.

                                   ARTICLE IV

                   ADMINISTRATION AND SERVICING OF CONTRACTS


Section 4.01.  Responsibility for Contract Administration and Servicing.
               --------------------------------------------------------     

     BankAmerica Housing Services hereby agrees to act as Servicer under this
Agreement.  The Certificateholders by their acceptance of the Certificates
consent to BankAmerica Housing Services acting as Servicer.  The Servicer shall
service and administer the Contracts and, subject to the terms of this
Agreement, shall have full power and authority to do any and all things which it
may deem necessary or desirable in connection with such servicing and
administration.  Subject to Section 4.02, without limiting the generality of the
foregoing, the Servicer hereby is authorized and empowered, when the Servicer
believes it appropriate in its best judgment, to execute and deliver, on behalf
of the Certificateholders and the Trust Fund or any of them, 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 Contracts,
with respect to the Manufactured Homes and with respect to the Mortgaged
Property.  The Trustee shall furnish the Servicer with any powers of attorney
and other documents necessary or appropriate to enable the Servicer to service
and administer the Contracts.  The relationship of the Servicer (and of any
successor to the Servicer as servicer under this Agreement) 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 of the Trustee.

Section 4.02.  Standard of Care.
               ----------------     

     In managing, administering, servicing and making collections on the
Contracts pursuant to this Agreement, the Servicer will, consistent with the
terms of this Agreement and applicable law, act with reasonable care, using that
degree of skill and care that it exercises with respect to similar manufactured
housing contracts owned and/or serviced by it, but in no event using a degree of
skill and care that is lower than that used generally in the servicing industry
for such manufactured housing contracts; provided, however, that notwithstanding
                                         --------  -------                      
the foregoing, the Servicer shall not release or waive the right to collect the
unpaid balance on any Contract.  Notwithstanding anything to the contrary
contained in this Agreement, no provision of this Agreement shall be construed
so as to require the Servicer to take any action or fail to take any action in
respect of a Contract which action or failure violates applicable law.

Section 4.03.  Records.
               -------     

     The Servicer, during the period it is servicer hereunder, shall maintain
such books of account and other records as will enable the Trustee (if the
Trustee so elects in its discretion) to determine the status of each Contract.
Without limiting the generality of the preceding sentence, the Servicer shall
keep such records in respect of Liquidation Expenses as will enable the Trustee
(if the Trustee so elects in its discretion) to determine that the correct
amount of Net Liquidation Proceeds in respect of a Liquidated Contract has been
deposited in the Certificate Account.

                                      -46-
<PAGE>
 
Section 4.04.  Inspection.
               ----------     

     (a)  At all times during the term hereof, the Servicer shall afford the
Trustee and its authorized agents reasonable access during normal business hours
to the Servicer's records relating to the Contracts and will cause its personnel
to assist in any examination of such records by the Trustee or any of its
authorized agents.  The examination referred to in this Section 4.04 will be
conducted in a manner which does not interfere unreasonably with the Servicer's
normal operations or customer or employee relations.  Without otherwise limiting
the scope of the examination which the Trustee may make, the Trustee or its
authorized agents, using generally accepted audit procedures, may in their
discretion verify the status of each Contract and review the records relating
thereto for conformity to Monthly Reports prepared pursuant to Article V and
compliance with the standards represented to exist as to each Contract in this
Agreement.

     (b)  At all times during the term hereof, the Servicer shall keep available
a copy of the Contract Schedule at its principal executive office for inspection
by Certificate Owners.

Section 4.05.  Establishment of and Deposits in Certificate Accounts.
               -----------------------------------------------------     

     On or before the Closing Date, the Trustee shall have established, and
thereafter shall maintain, a Certificate Account which is an Eligible Account,
in the form of a segregated trust account titled "BankAmerica Manufactured
Housing Contract Trust III, Senior/Subordinate Pass-Through Certificates, Series
1997-2, Certificate Account in trust for the Trustee as trustee for the benefit
of the Certificateholders."  As of the Closing Date, the Certificate Account
shall be a segregated trust account established at The First National Bank of
Chicago and shall be invested in the Trustee's Corporate Trust Short-Term
Investment Fund (as long as such fund is an Eligible Investment) or other
similar Eligible Investment selected by the Trustee.  Eligible Investments shall
mature or, in the case of a money market fund, be redeemed not later than the
Business Day immediately preceding the Distribution Date next following the date
of such investment (except that, if such Eligible Investment is an obligation of
the institution that maintains the Certificate Account, then such Eligible
Investments shall mature or, in the case of a money market fund, be redeemed not
later than such Distribution Date), and shall not be sold or disposed of prior
to its maturity.  All such Eligible Investments shall be made in the name of the
Trustee, as trustee for the benefit of the Certificateholders.  Without limiting
the generality of the foregoing, the Trustee shall select obligations for the
investment of the Certificate Account from among the investments specified in
clauses (a) and (b) of the definition of "Eligible Investments."  The Trustee
shall select such Eligible Investments, which shall mature as provided above, in
such manner as to achieve the following objectives in the order stated:  (1)
preservation of principal values; and (2) maximization of income.

     All net income and gain realized from any such investments, to the extent
provided by this Agreement, shall be added to the Certificate Account.

     The Servicer shall deposit in the Certificate Account, as promptly as
practicable (but not later than the close of business of the second Business
Day) following receipt thereof:

          (1)  All amounts received from Obligors with respect to principal of
     and interest on the Contracts (including Excess Contract Payments);

                                      -47-
<PAGE>
 
          (2)  All Net Liquidation Proceeds;

          (3)  All amounts required to be deposited by the Contract Seller
     pursuant to Sections 3.05(a) and (b);

          (4)  All Monthly Advances pursuant to Section 5.01;

          (5)  Any proceeds of Hazard Insurance Policies pursuant to Section
     4.11 and any amounts in respect of indemnification pursuant to Section
     7.03; and

          (6)  All amounts required to be withdrawn from an REO Account and
     deposited in the Certificate Account in accordance with Section 4.17.

Section 4.06.  Payment of Taxes.
               ----------------     

     If the Servicer becomes aware of the nonpayment by an Obligor of a real or
personal property tax or other tax or charge which may result in a lien upon a
Manufactured Home or Mortgaged Property prior to, or equal to or coordinate
with, the lien of the related Contract, the Servicer, consistent with Section
4.02, shall take action, including the payment of such taxes or charges to avoid
the attachment of any such lien.  If the Servicer shall have paid any such real
or personal property tax or other tax or charge directly on behalf of an
Obligor, the Servicer shall seek reimbursement therefor only from the related
Obligor (except as provided in the last sentence of this Section 4.06) and may
separately add such amount to the Obligor's obligation as provided by the
Contract, but, for the purposes of this Agreement, may not add such amount to
the remaining principal balance of the Contract.  If the Servicer shall have
repossessed a Manufactured Home or Mortgaged Property on behalf of the
Certificateholders and the Trustee, the Servicer shall pay the amount of any
such tax or charge arising during the time such Manufactured Home is in the
Servicer's possession or title to the Mortgaged Property is in the name of the
Servicer (or any Person acting on behalf of the Servicer), unless the Servicer
is contesting in good faith such tax or charge or the validity of the claimed
lien on such Manufactured Home or Mortgaged Property.  If the Obligor does not
reimburse the Servicer for payment of such taxes or charges pursuant to this
Section 4.06 and the related Contract is liquidated after a default, the
Servicer shall be reimbursed for its payment of such taxes or charges out of the
related Liquidation Proceeds.

Section 4.07.  Enforcement.
               -----------     

     (a)  The Servicer, consistent with Section 4.02, shall act with respect to
the Contracts in such manner as will maximize the receipt of principal and
interest on such Contracts.

     (b)  The Servicer shall sue to enforce or collect upon Contracts, in its
own name, if possible, or as agent for the Trust Fund.  If the Servicer elects
to commence a legal proceeding to enforce a Contract, the act of commencement
shall be deemed to be an automatic assignment of the Contract to the Servicer
for purposes of collection only. If, however, in any enforcement suit or legal
proceeding it is held that the Servicer may not enforce a Contract on the ground
that it is not a real party in interest or a holder entitled to enforce the
Contract, the Trustee on behalf of the Certificateholders shall, at the
Servicer's expense, take such steps as the Servicer deems necessary

                                      -48-
<PAGE>
 
to enforce the Contract, including bringing suit in its name or the names of the
Certificateholders. If there has been a recovery of attorneys' fees in favor of
the Servicer or the Trust Fund in an action involving the enforcement of a
Contract, the Servicer shall be reimbursed out of such recovery for its out-of-
pocket attorney's fees and expenses incurred in such enforcement action.

     (c)  The Servicer shall exercise any rights of recourse against third
persons that exist with respect to any Contract in accordance with Section 4.02.
In exercising recourse rights, the Servicer is authorized on the Trustee's
behalf to reassign the Contract or to resell the related Manufactured Home and,
if applicable, the Mortgaged Property, to the Person against whom recourse
exists at the price set forth in the document creating the recourse.

     (d)  The Servicer may grant to the Obligor on any Contract any rebate,
refund or adjustment out of the Certificate Account that is required because of
an overpayment in connection with the partial prepayment or prepayment in full
of the Contract or otherwise.  The Servicer may rescind, cancel or make material
modifications of the terms of any Contract (including modifying the amounts and
due dates of scheduled monthly payments); provided that, unless required by
                                          --------                         
applicable law or to bring Contracts into conformity with the representations
and warranties contained in Article III, the Servicer will not permit any
rescission or cancellation of any Contract or any material modification of a
Contract other than in connection with a default or an imminent default on such
Contract unless the Servicer obtains an Opinion of Counsel to the effect that
such modification will not cause the Trust Fund to fail to qualify as a REMIC or
result in the imposition of taxes on the Trust Fund under the REMIC Provisions.

Section 4.08.  Transfer of Certificate Account.
               -------------------------------     

     The Trustee may transfer the Certificate Account to a different depository
institution from time to time, so long as the Certificate Account remains an
Eligible Account.  The Trustee shall give notice of any transfer of the
Certificate Account to each Rating Agency prior to such transfer.

Section 4.09.  Maintenance of Hazard Insurance Policies.
               ----------------------------------------     

     (a)  Except as otherwise provided in subsection (b) of this Section 4.09,
the Servicer shall cause to be maintained with respect to each Contract one or
more Hazard Insurance Policies which provide, at a minimum, the same coverage as
a standard form fire and extended coverage insurance policy that is customary
for manufactured housing, issued by a company authorized to issue such policies
in the state in which the Manufactured Home is located, and in an amount which
is not less than the maximum insurable value of such Manufactured Home or the
principal balance of the related Contract, whichever is less; provided that such
                                                              --------          
Hazard Insurance Policies may provide for customary deductible amounts, and
                                                                           
further provided that the amount of coverage provided by each Hazard Insurance
- ------- --------                                                              
Policy shall be sufficient to avoid the application of any co-insurance clause
contained therein.  If a Manufactured Home is located within a federally
designated special flood hazard area, the Servicer shall, to the extent required
by applicable law or regulation, also cause flood insurance to be maintained,
which coverage shall be at least equal to the minimum amount specified in the
preceding sentence or such lesser amount as may be available under the federal
flood insurance program. Each Hazard Insurance Policy caused to be

                                      -49-
<PAGE>
 
maintained by the Servicer shall contain a standard loss payee clause in favor
of the Servicer and its successors and assigns. If any Obligor is in default in
the payment of premiums on its Hazard Insurance Policy or Policies, the Servicer
shall pay such premiums out of its own funds, and may add separately such
premium to the Obligor's obligation as provided by the Contract, but may not add
such premium to the remaining principal balance of the Contract for purposes of
this Agreement. If the Obligor does not reimburse the Servicer for payment of
such premiums and the related Contract is liquidated after a default, the
Servicer shall be reimbursed for its payment of such premiums out of the related
Liquidation Proceeds.

     (b)  The Servicer may, in lieu of causing individual Hazard Insurance
Policies to be maintained with respect to each Manufactured Home pursuant to
subsection (a) of this Section 4.09, and shall, to the extent that the related
Contract does not require the Obligor to maintain a Hazard Insurance Policy with
respect to the related Manufactured Home, maintain one or more blanket insurance
policies covering losses as provided in subsection (a) of this Section 4.09
resulting from the absence or insufficiency of individual Hazard Insurance
Policies.  Any such blanket policy shall be substantially in the form that is
the industry standard for blanket insurance policies issued to cover
Manufactured Homes and in the amount sufficient to cover all losses on the
Contracts.  The Servicer shall pay, out of its own funds, the premium for such
policy on the basis described therein and shall deposit in the Certificate
Account, on the Business Day next preceding the Determination Date following the
Collection Period in which the insurance proceeds from claims in respect of any
Contracts under such blanket policy are or should have been received, the
deductible amount with respect to such claims.  The Servicer shall not, however,
be required to deposit any deductible amount with respect to claims under
individual Hazard Insurance Policies maintained pursuant to subsection (a) of
this Section 4.09.

     (c)  If the Servicer shall have repossessed a Manufactured Home on behalf
of the Trustee, the Servicer shall either (i) maintain at its expense a Hazard
Insurance Policy with respect to such Manufactured Home, except that the
Servicer shall be responsible for depositing any deductible amount with respect
to all claims under individual Hazard Insurance Policies, or (ii) indemnify the
Trust Fund against any damage to such Manufactured Home prior to resale or other
disposition that would have been covered by such Hazard Insurance Policy.

     (d)  Any cost incurred by the Servicer in maintaining any of the foregoing
insurance, for the purpose of calculating monthly distributions to
Certificateholders, shall not be added to the amount owing under the Contract,
notwithstanding that the terms of the Contract so permit.  The Servicer shall
not be entitled to reimbursement from the Contract Seller, the Trustee or the
Certificateholders for such costs.  Such costs (other than the cost of the
blanket policy) shall only be recovered out of later payments by the Obligor for
such premiums or, if the related Contract is liquidated after a default, out of
the related Liquidation Proceeds.

Section 4.10.  Fidelity Bond and Errors and Omissions Insurance.
               ------------------------------------------------     

     The Servicer shall maintain, at its own expense, a blanket fidelity bond
and an errors and omissions insurance policy, with broad coverage with
responsible companies acceptable to FNMA and FHLMC, on all officers, employees
or other persons acting in any capacity with regard to the Contracts to handle
funds, money, documents and papers relating to the Contracts.  Any such

                                      -50-
<PAGE>
 
fidelity bond and errors and omissions insurance 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
4.10 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. The minimum coverage under any such bond and insurance policy
shall be in an amount as is customary for servicers that service a portfolio of
manufactured housing installment sales contracts of $100 million or more and
that are generally acceptable as servicers to institutional investors. On or
before April 1 of every year, the Servicer shall cause to be delivered to the
Trustee a certified true copy of such fidelity bond and insurance policy and a
statement from the surety and the insurer that such fidelity bond or insurance
policy shall in no event be terminated or materially modified without 30 days'
prior written notice to the Trustee.

Section 4.11.  Collections under Hazard Insurance Policies; Consent to Transfers
               -----------------------------------------------------------------
               of Manufactured Homes; Assumption Agreements.
               --------------------------------------------     

     (a)  In connection with its activities as administrator and servicer of the
Contracts, the Servicer agrees to present, on behalf of itself, the Trustee and
the Certificateholders, claims to the insurer under any Hazard Insurance
Policies and, in this regard, to take such reasonable action as shall be
necessary to permit recovery under any Hazard Insurance Policies or any blanket
policies obtained pursuant to Section 4.09(b).  Any amounts collected by the
Servicer under any such Hazard Insurance Policies shall be deposited in the
Certificate Account pursuant to Section 4.05, except to the extent they are
applied to the restoration of the related Manufactured Home or released to the
related Obligor in accordance with the normal servicing procedures of the
Servicer.

     (b)  In connection with any transfer of ownership of a Manufactured Home by
an Obligor to a Person, the Servicer shall consent to any such transfer and
permit the assumption by such Person of the Contract related to such
Manufactured Home, provided that (i) such Person, in the judgment of the
                   --------                                             
Servicer, meets the Servicer's underwriting standards then in effect, (ii) such
Person enters into an assumption agreement, (iii) the Servicer determines that
permitting such assumption by such Person will not materially increase the risk
of nonpayment of such Contract and (iv) such action will not adversely affect or
jeopardize any coverage under any insurance policy required by this Agreement.
In the event the Servicer determines that the conditions of the proviso of the
preceding sentence have not been fulfilled, then the Servicer shall withhold its
consent to any such transfer, but only to the extent permitted under the
Contract and applicable law and governmental regulations and only to the extent
that such action will not adversely affect or jeopardize any coverage under any
insurance policy required by this Agreement.  In connection with any such
assumption, the rate of interest borne by, and all other material terms of, the
related Contract shall not be changed.

     (c)  In any case in which a Manufactured Home or Mortgaged Property is to
be conveyed to a Person by an Obligor, and such Person is to enter into an
assumption agreement or modification agreement or supplement to the Contract in
accordance with Section 4.11(b) or Section 4.07(d), upon the closing of such
conveyance, the Servicer shall cause the originals of the assumption agreement,
the release (if any), or the modification or supplement to the Contract to be
deposited with the Contract File or the Land Home Contract File, as applicable,
for such

                                      -51-
<PAGE>
 
Contract.  Any fee collected by the Servicer for entering into an
assumption or substitution of liability agreement with respect to such Contract
will be retained by the Servicer as additional servicing compensation.

Section 4.12.  Realization upon Defaulted Contracts.
               ------------------------------------     

     Subject to applicable law, the Servicer shall repossess, foreclose upon or
otherwise comparably convert the ownership of Manufactured Homes  and Mortgaged
Property securing all Contracts that come into default and which the Servicer
believes in its good faith business judgment will not be brought current.
Subject to Section 4.17, the Servicer shall manage, conserve and protect such
Manufactured Homes and Mortgaged Property for the purposes of their prompt
disposition and sale, and shall dispose of such Manufactured Homes and Mortgaged
Property on such terms and conditions as it deems in the best interests of the
Certificateholders.  If the Servicer has actual knowledge that a Mortgaged
Property is affected by hazardous waste, then the Servicer shall not cause the
Contract Seller to acquire title to such Mortgaged Property in a foreclosure or
similar proceeding.  For purposes of the proviso in the preceding sentence, the
Servicer shall not be deemed to have actual knowledge that a Mortgaged Property
is affected by hazardous waste unless it shall have received written notice that
hazardous waste is present on such property and such written notice has been
made a part of the Land Home Contract File with respect to the related Contract.
In connection with such activities, the Servicer shall follow such practices and
procedures as are consistent with Section 4.02.

Section 4.13.  Costs and Expenses.
               ------------------     

     Except as otherwise expressly provided herein, all costs and expenses
incurred by the Servicer in carrying out its duties under this Agreement,
including all fees and expenses incurred in connection with the enforcement of
Contracts (including enforcement of defaulted Contracts and repossessions of
Manufactured Homes and Mortgaged Property securing such Contracts), shall be
paid by the Servicer, and the Servicer shall not be entitled to reimbursement
hereunder, except to the extent such reimbursement is specifically provided for
in this Agreement.  Notwithstanding the foregoing, the Servicer shall be
reimbursed out of the Liquidation Proceeds of a defaulted Contract for
Liquidation Expenses incurred by it in realizing upon the related Manufactured
Home and Mortgaged Property, including, but not limited to:  (i) costs of
refurbishing and securing such Manufactured Home; (ii) transportation expenses
incurred in moving the Manufactured Home; (iii) reasonable legal fees and
expenses of outside counsel; and (iv) sales commissions paid to Persons that are
not Affiliates of the Servicer.  The Servicer shall not incur any Liquidation
Expenses unless it determines in its good faith business judgment that incurring
such expenses will increase the Net Liquidation Proceeds from such Manufactured
Home and Mortgaged Property.

Section 4.14.  Trustee to Cooperate.
               --------------------     

     (a)  Upon payment in full of any Contract, the Servicer will notify the
Trustee on the next Distribution Date by a certificate of a Servicing Officer
(which certification shall include a statement to the effect that all amounts
received or to be received in connection with such payment which are required to
be deposited in the Certificate Account pursuant to Section 4.05

                                      -52-
<PAGE>

have been deposited). The Servicer is authorized to execute an instrument in
satisfaction of such Contract and to do such other acts and execute such other
documents as the Servicer deems necessary to discharge the Obligor thereunder
and eliminate the security interest in the Manufactured Home. The Servicer shall
determine when a Contract has been paid in full. To the extent insufficient
payments are received on a Contract mistakenly determined by the Servicer to be
prepaid or paid in full and satisfied, the shortfall shall be paid by the
Servicer out of its own funds by deposit into the Certificate Account.

     (b)  From time to time as appropriate for servicing and foreclosure in
connection with any Land Home Contract, the Trustee shall, upon written request
of a Servicing Officer and delivery to the Trustee of a receipt signed by such
Servicing Officer, cause the original Land Home Contract and the related Land
Home Contract File to be released to the Servicer and shall execute such
documents as the Servicer shall deem necessary to the prosecution of any such
proceedings.  The Trustee shall stamp the face of each such Land Home Contract
to be released to the Servicer with a notation that the Land Home Contract has
been assigned to the Trustee.

     (c)  The Servicer's receipt of a Land Home Contract and/or Land Home
Contract File shall obligate the Servicer to return the original Land Home
Contract and the related Land Home Contract File to the Trustee, or any person
acting on behalf of the Trustee, when its need by the Servicer has ceased unless
the Contract shall be liquidated, repurchased or replaced as described in
Section 3.05.

     (d)  Upon request of a Servicing Officer, the Trustee shall, at the expense
of the Servicer, perform such acts as are reasonably requested by the Servicer
(including the execution of documents) and otherwise cooperate with the Servicer
in the enforcement of rights and remedies with respect to Contracts.

Section 4.15.  Servicing and Other Compensation.
               --------------------------------     

     The Servicer, as compensation for its activities hereunder including the
payment of fees and expenses of the Trustee, the Certificate Administrator and
the Paying Agent pursuant to Section 9.05, shall be entitled to receive on each
Distribution Date the Monthly Servicing Fee and Repossession Profits pursuant to
Section 5.03.

     Additional servicing compensation in the form of Late Payment Fees or
Extension Fees and any transfer of equity or assumption fees shall be retained
by the Servicer.  The Servicer shall not be reimbursed for its costs and
expenses in servicing the Contracts except as otherwise expressly provided
herein.

     No transfer, sale pledge or other disposition of the Servicer's right to
receive all or any portion of the Monthly Servicing Fee shall be made, and any
such attempted transfer, sale, pledge or other disposition shall be void, unless
such transfer is made to a successor Servicer in connection with the assumption
by such successor Servicer of the duties hereunder pursuant to Section 7.07 and
all (and not a portion) of the Monthly Servicing Fee is transferred to such
successor Servicer.

Section 4.16.  Custody of Contracts.
               --------------------     

     (a)  Subject to the terms and conditions of this Section 4.16, the Servicer
agrees to act as custodian of the Contract Files and the Land Home Contract
Files for the benefit of the Certificateholders and the Trust Fund.  The
Certificateholders by their acceptance of the Certificates, consent to the
Servicer acting as custodian, and the Servicer agrees to maintain the Contract
Files and the Land Home Contract Files as custodian therefor.

     (b)  The Servicer agrees to maintain the related Contract Files and the
Land Home Contract Files at its offices where they are presently maintained, or
at such other offices of the Servicer in the State of California as shall from
time to time be identified to the Trustee by ten days' prior written notice. The
Servicer may temporarily move individual Contract Files, Land Home Contract
Files or, in each case, any portion thereof without notice as necessary to
conduct collection and other servicing activities in accordance with its
customary practices and procedures.

     (c)  As custodian, the Servicer shall have and perform the following powers
and duties:

          (i)  hold the Contract Files and the Land Home Contract Files on
     behalf of the Certificateholders and the Trustee, maintain accurate records
     pertaining to each Contract to enable it to comply with the terms and
     conditions of this Agreement, maintain a current inventory thereof and
     conduct annual physical inspections of Contract Files and the Land Home
     Contract Files held by it under this Agreement;

          (ii)  implement policies and procedures in writing and signed by a
     Servicing Officer, with respect to persons authorized to have access to the
     Contract Files and the Land Home Contract Files on the Servicer's premises
     and the receipting for Contract Files and Land Home Contract Files taken
     from their storage area by an employee of the Servicer for purposes of
     servicing or any other purposes; and

          (iii)  attend to all details in connection with maintaining custody of
     the Contract Files and the Land Home Contract Files on behalf of the
     Certificateholders and the Trustee.

     (d)  In performing its duties under this Section 4.16, the Servicer agrees
to act in accordance with the standard of care set forth in Section 4.02.  The
Servicer shall promptly report to the Trustee any failure by it to hold the
Contract Files or the Land Home Contract Files as herein provided, and shall
promptly take appropriate action to remedy any such failure.  In acting as
custodian of the Contract Files and the Land Home Contract Files, the Servicer
further agrees not to assert any beneficial ownership interests in the
Contracts, the Contract Files or the Land Home Contract Files.  The Servicer
agrees to indemnify the Certificateholders and the Trustee for any and all
liabilities, obligations, losses, damages, payments, costs or expenses of any
kind whatsoever which may be imposed on, incurred or asserted against the
Certificateholders and the Trustee as the result of any act or omission by the
Servicer relating to the maintenance and custody of the Contract Files and the
Land Home Contract Files; provided, however, that the
                          --------  -------                   

                                      -54-
<PAGE>
 
Servicer will not be liable for any portion of any such amount resulting from
the negligence or willful misconduct of any other Person.

     (e)  If the Servicer obtains actual notice of or knowledge that the
Servicer does not have a long-term senior debt rating from Moody's of A3 or
higher, or an equivalent rating from any nationally recognized statistical
rating organization, then the Servicer shall promptly deliver the Land Home
Contract Files, together with assignments in recordable form, to the Trustee or
another custodian designated by the Trustee, and the Trustee agrees that upon
such delivery it shall maintain, or cause such custodian to maintain, the Land
Home Contract Files.

Section 4.17.  REMIC Compliance.
               ----------------     

     (a) The REMIC Administrator shall make an election to treat the Trust Fund
as a REMIC under the Code and, if necessary, under applicable state law.  Such
election will be made on Form 1066 or other appropriate federal tax or
information return (including Form 8811) or any appropriate state return for the
taxable year ending on the last day of the calendar year in which the
Certificates are issued.  For the purposes of the REMIC election in respect of
the Trust Fund, each of the Class A, Class M and Class B Certificates shall be
designated as the "regular interests" and the Class R Certificates shall be
designated as the sole class of "residual interests" in the REMIC.  The REMIC
Administrator and the Trustee shall not permit the creation of any "interests"
(within the meaning of Section 860G of the Code) in the REMIC other than the
Certificates.

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

     (c) The REMIC Administrator shall at all times hold a Class R Certificate
representing a 0.01% Percentage Interest of all Class R Certificates and shall
be designated as "the tax matters person" with respect to the REMIC in the
manner provided under Treasury regulations section 1.860F-4(d) and temporary
Treasury regulations section 301.6231(a)(7)-1T.  The REMIC Administrator, as tax
matters person, shall (i) act on behalf of the REMIC in relation to any tax
matter or controversy involving the Trust Fund and (ii) represent the Trust Fund
in any administrative or judicial proceeding relating to an examination or audit
by any governmental taxing authority with respect thereto.  The legal expenses,
including without limitation attorneys' or accountants' fees, and costs of any
such proceeding and any liability resulting therefrom shall be expenses of the
Trust Fund and the REMIC Administrator shall be entitled to reimbursement
therefor out of amounts attributable to the Contracts on deposit in the
Certificate Account provided by Section 5.03 unless such legal expenses and
costs are incurred by reason of the Servicer's willful misfeasance, bad faith or
gross negligence.  If the REMIC Administrator is no longer the Servicer
hereunder, at its option the REMIC Administrator may continue its duties as
tax matters person and shall be paid reasonable compensation not to exceed
$3,000 per year by any successor Servicer hereunder for so acting as the REMIC
Administrator.

     (d) The REMIC Administrator shall prepare or cause to be prepared all of
the tax returns that it determines are required with respect to the REMIC
created hereunder and deliver such tax returns in a timely manner to the Trustee
and the Trustee shall sign and file such tax

                                      -55-
<PAGE>

returns in a timely manner. The expenses of preparing such returns shall be
borne by the REMIC Administrator without any right of reimbursement therefor.
The REMIC Administrator agrees to indemnify and hold harmless the Trustee with
respect to any tax liability arising from the Trustee's signing of tax returns
that contain errors or omissions. The Trustee and Servicer shall promptly
provide the REMIC Administrator with such information as the REMIC Administrator
may from time to time request for the purpose of enabling the REMIC
Administrator to prepare tax returns.

     (e) The REMIC Administrator shall provide (i) to any transferor of a Class
R Certificate such information as is necessary for the application of any tax
relating to the transfer of a Class R Certificate to any Person who is not a
Permitted Transferee, (ii) to the Trustee and the Trustee shall forward to the
Certificateholders such information or reports as are required by the Code or
the REMIC Provisions including reports relating to interest, original issue
discount and market discount or premium (using the Prepayment Assumption) and
(iii) to the Internal Revenue Service the name, title, address and telephone
number of the person who will serve as the representative of the REMIC.

     (f) The REMIC Administrator and the Servicer shall take such actions and
shall cause the REMIC created hereunder to take such actions as are reasonably
within the REMIC Administrator's or the Servicer's control and the scope of its
duties more specifically set forth herein as shall be necessary or desirable to
maintain the status thereof as a REMIC under the REMIC Provisions (and the
Trustee shall assist the Servicer and the REMIC Administrator, to the extent
reasonably requested by the Servicer and the REMIC Administrator to do so).  The
REMIC Administrator and the Servicer shall not knowingly or intentionally take
any action, cause the Trust Fund to take any action or fail to take (or fail to
cause to be taken) any action reasonably within their respective control that,
under the REMIC Provisions, if taken or not taken, as the case may be, could (i)
endanger the status of the REMIC as a REMIC or (ii) result in the imposition of
a tax upon the REMIC (including but not limited to the tax on prohibited
transactions as defined in Section 860F(a)(2) of the Code and the tax on
contributions to a REMIC set forth in Section 860(G)(d) of the Code) (either
such event, in the absence of an Opinion of Counsel or the indemnification
referred to in this sentence, an "Adverse REMIC Event") unless the REMIC
Administrator or the Servicer, as applicable, has received an Opinion of Counsel
(at the expense of the party seeking to take such action or, if such party fails
to pay such expense, and the REMIC Administrator or the Servicer, as applicable,
determines that taking such action is in the best interest of the Trust Fund and
the Certificateholders, at the expense of the Trust Fund, but in no event at the
expense of the REMIC Administrator, the Contract Seller, the Servicer or the
Trustee) to the effect that the contemplated action will not, with respect to
the REMIC created hereunder, endanger such status or, unless the REMIC
Administrator, the Servicer or both, as applicable, determine in its or their
sole discretion to indemnify the Trust Fund against the imposition of such a
tax, result in the imposition of such a tax. Wherever in this Agreement a
contemplated action may not be taken because the timing of such action might
result in the imposition of a tax on the Trust Fund, or may only be taken
pursuant to an Opinion of Counsel that such action would not impose a tax on the
Trust Fund, such action may nonetheless be taken provided that the indemnity
given in the preceding sentence with respect to any taxes that might be imposed
on the Trust Fund has been given and that all other preconditions to the taking
of such action have been satisfied. The Trustee shall not take or fail to take
any action (whether or not authorized hereunder) as to which the REMIC
Administrator or the Servicer, as

                                      -56-
<PAGE>
 
applicable, has advised it in writing that it has received an Opinion of Counsel
to the effect that an Adverse REMIC Event could occur with respect to such
action. In addition, prior to taking any action with respect to the REMIC or its
assets, or causing the REMIC to take any action, which is not expressly
permitted under the terms of this Agreement, the Trustee will consult with the
REMIC Administrator or the Servicer, as applicable, or its designee, in writing,
with respect to whether such action could cause an Adverse REMIC Event to occur
with respect to the REMIC, and the Trustee shall not take any such action or
cause the REMIC to take any such action as to which the REMIC Administrator or
the Servicer, as applicable, has advised it in writing that an Adverse REMIC
Event could occur. The REMIC Administrator or the Servicer, as applicable, may
consult with counsel to make such written advice, and the cost of same shall be
borne by the party seeking to take the action not expressly permitted by this
Agreement, but in no event at the expense of the REMIC Administrator or the
Servicer. At all times as may be required by the Code, the Servicer will to the
extent within its control and the scope of its duties more specifically set
forth herein, maintain substantially all of the assets of the REMIC as
"qualified mortgages" as defined in Section 860G(a)(3) of the Code and
"permitted investments" as defined in Section 860G(a)(5) of the Code.

     (g) In the event that any tax, including interest, penalties, additional
amounts or additions to tax (a "Tax"), is imposed on the Trust Fund, such Tax
shall be charged against amounts otherwise required to be distributed to the
Holders of the Class R Certificates.  The Trustee is hereby authorized to
retain, or cause the Paying Agent to retain, from amounts otherwise required to
be distributed to the Holders of the Class R Certificates sufficient funds to
pay or provide for the payment of, and to actually pay, or cause the Paying
Agent to pay, such Tax as is legally owed by the Trust Fund (but such
authorization shall not prevent the Servicer from contesting any such Tax in
appropriate proceedings, and withholding payment of such Tax, if permitted by
law, pending the outcome of such proceedings).  To the extent that sufficient
amounts cannot be so retained to pay or provide for the payment of any tax
imposed on gain realized from any prohibited transaction (as defined in the
REMIC Provisions), the Trustee is hereby authorized to and shall segregate, into
a separate non-interest-bearing account, the net income from such prohibited
transactions and pay, or cause the Paying Agent to pay, such Tax.  In the event
any (i) amounts initially retained from amounts required to be distributed to
the Holders of the Class R Certificates and (ii) income so segregated and
applied towards the payment of such Tax shall not be sufficient to pay such Tax
in its entirety, the amount of the shortfall shall be paid from funds in the
Certificate Account notwithstanding anything to the contrary contained herein.
To the extent any such segregated income or funds from the Certificate Account
are paid to the Internal Revenue Service, the Trustee shall retain, or cause to
be retained, an amount equal to the amount of such income or funds so paid from
future amounts otherwise required to be distributed to the Holders of the Class
R Certificates and shall deposit such retained amounts in the Certificate
Account for distribution to the Holders of the Regular Certificates.

     (h) The Trustee and the Servicer shall, for federal income tax purposes,
maintain books and records with respect to the REMIC on a calendar year and on
an accrual basis or as otherwise may be required by the REMIC Provisions.

     (i) Following the Startup Day, neither the Servicer nor the Trustee shall
accept any contributions of assets to the REMIC unless (subject to Section
4.17(f)) the Servicer and the 

                                      -57-
<PAGE>
 
Trustee shall have received an Opinion of Counsel (at the expense of the party
seeking to make such contributions) to the effect that the inclusion of such
assets in the REMIC will not cause the REMIC to fail to qualify as a REMIC at
any time that any Certificates are outstanding or subject the REMIC to any tax
under the REMIC Provisions or other applicable provisions of federal, state and
local law or ordinances.

     (j) Neither the Servicer nor the Trustee shall (subject to Section 4.17(f))
enter into any arrangement by which the REMIC will receive a fee or other
compensation for services nor permit the REMIC to receive any income from assets
other than "qualified mortgages" as defined in Section 860G(a)(3) of the Code or
"permitted investments" as defined in Section 860G(a)(5) of the Code.

     (k) Solely for the purposes of Section 1.860G-1(a)(4)(iii) of the Treasury
Regulations, the "latest possible maturity date" by which the Certificate
Balance of each Class of Certificates representing a regular interest in the
REMIC would be reduced to zero is October 10, 2027 which is the Distribution
Date immediately following the latest schedule maturity of any Contract.

     (l) Within 30 days after the Closing Date, the REMIC Administrator shall
prepare and file with the Internal Revenue Service Form 8811, "Information
Return for Real Estate Mortgage Investment Conduits (REMIC) and Issuers of
Collateralized Debt Obligations" for the REMIC.

     (m) Neither the Trustee nor the Servicer shall sell, dispose of or
substitute for any of the Contracts (except in connection with (i) the default,
imminent default or foreclosure of a Contract, including but not limited to, the
acquisition or sale of a Manufactured Home or a Mortgaged Property acquired by
deed in lieu of foreclosure, (ii) the bankruptcy of the REMIC, (iii) the
termination of the REMIC pursuant to Article X of this Agreement or (iv) a
purchase of Contracts pursuant to Article III of this Agreement) nor acquire any
assets for the REMIC, nor sell or dispose of any investments in the Certificate
Account for gain nor accept any contributions to the REMIC after the Closing
Date unless it has received an Opinion of Counsel that such sale, disposition,
substitution or acquisition will not (a) affect adversely the status of the
REMIC as a REMIC or (b) unless the Servicer has determined in its sole
discretion to indemnify the Trust Fund against such tax, cause the REMIC to be
subject to a tax on "prohibited transactions" or "contributions" pursuant to the
REMIC Provisions.

     (n) Each Holder of a Class R Certificate, by purchasing such Class R
Certificate, agrees to give the Servicer written notice that it is a "pass-
through interest holder" within the meaning of Temporary Treasury Regulations
Section 1.67-3T(a)(2)(i)(A) immediately upon becoming the Holder of such Class R
Certificate, if it is, or is holding such Class R Certificate on behalf of, a
"pass-through interest holder."

     (o) In the event that any Manufactured Home or Mortgaged Property is
acquired in a repossession (an "REO Property"), the Servicer shall sell any REO
Property within three years of its acquisition by the Trust Fund, unless (i) at
least 60 days before such three-year period would otherwise expire, the Servicer
applies for an extension of such three-year period pursuant to Sections
856(e)(3) and 860G(a)(8)(A) of the Code, in which case the Servicer shall sell
such REO Property within the applicable extension period or (ii) at the request
of the Servicer, the Trustee

                                      -58-
<PAGE>
 
seeks, and subsequently receives, an Opinion of Counsel, addressed to the
Trustee and the Servicer, to the effect that the holding by the Trust Fund of
such REO Property subsequent to three years after its acquisition will not
result in the imposition of taxes on "prohibited transactions" of the Trust Fund
as defined in Section 860F of the Code or cause the Trust Fund to fail to
qualify as a REMIC at any time that any Certificates are outstanding. The
Servicer shall manage, conserve, protect and operate each REO Property solely
for the purpose of its prompt disposition and sale in a manner that does not
cause any such REO Property to fail to qualify as "foreclosure property" within
the meaning of Section 860G(a)(8) of the Code or result in the receipt by the
REMIC of any "income from non-permitted assets" within the meaning of Section
860F(a)(2)(B) of the Code or any "net income from foreclosure property" which is
subject to taxation under the REMIC Provisions. In connection with 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 REO
Property is located and may, incident to its conservation and protection of the
interests of the Certificateholders, rent the same, or any part thereof, as the
Servicer deems to be in the best interest of the Servicer and the
Certificateholders for the period prior to the sale of such REO Property.

     (p) The Servicer shall segregate and hold all funds collected and received
in connection with the operation of any REO Property separate and apart from its
own funds and general assets and shall establish and maintain with respect to
each REO Property an account held in trust for the Trustee for the benefit of
the Certificateholders (each, an "REO Account"), which shall be an Eligible
Account and the funds therein shall be invested in Eligible Investments that
will mature not later than the Business Day preceding the applicable
Determination Date.  The Servicer shall be entitled to retain or withdraw any
interest income paid on funds deposited in each REO Account by the depository.

     (q) The Servicer shall deposit, or cause to be deposited, on a daily basis
in each REO Account all revenues received with respect to operation of the
related REO Property and shall withdraw therefrom funds necessary for the proper
operation, management and maintenance of the REO Property.  On or before each
Determination Date, the Servicer shall withdraw from each REO Account and
deliver to the Trustee for deposit into the Certificate Account the income from
the REO Property on deposit in the REO Account, net of its reasonable fees and
expenses.

     (r) The disposition of REO Property shall be carried out by the Servicer at
such price and upon such terms and conditions as the Servicer shall deem
necessary or advisable, as shall be normal and usual in its general servicing
activities.

     (s) The proceeds from the disposition of any REO Property, net of any
reimbursement to the Servicer as provided above, shall be deposited in the REO
Account and shall be deposited in the Certificate Account when the related

Section 4.18.  Management of REO Property.
               --------------------------     

     (a)  If the Trustee acquires any REO Property pursuant to Section 4.17, the
Servicer shall have full power and authority, subject only to the specific
requirements and prohibitions of

                                      -59-
<PAGE>
 
this Agreement, to do any and all things in connection therewith as are
consistent with the manner in which the Servicer manages and operates similar
property owned by the Servicer or any of its Affiliates, all on such terms and
for such period as the Servicer deems to be in the best interests of
Certificateholders, and, consistent therewith, shall withdraw from the REO
Account, to the extent of amounts on deposit therein with respect to such REO
Property, funds necessary for the proper operation, management and maintenance
of such REO Property, including:

          (i)  all insurance premiums due and payable in respect to such REO
     Property;

          (ii)  all real estate taxes and assessments in respect to such REO
     Property that may result in the imposition of a lien thereon; and

          (iii)  all costs and expenses necessary to maintain such REO Property.

     To the extent that amounts on deposit in the REO Account in respect of any
REO Property are insufficient for the purposes set forth in (i)-(iii) above with
respect to such REO Property, the Servicer shall advance from its own funds such
amount as is necessary for such purposes if, but only if, the Servicer would
make such advances if the Servicer owned such REO Property and if in the
Servicer's judgment, the payment of such amounts will be recoverable from the
operation or sale of such REO Property.

     (b)  Notwithstanding the foregoing, the Servicer shall not:

          (i)  authorize or permit any construction on any REO Property, other
     than the completion of a building or other improvement thereon, and then
     only if more than ten percent of the construction of such building or other
     improvement was completed before default on the related Contract became
     imminent, all within the meaning of Section 856(e)(4)(B) of the Code; or

          (ii)  directly operate, or allow any other Person to directly operate,
     any REO Property on any date more than 90 days after its date of
     acquisition;

unless, in any such case, the Servicer has requested and received an Opinion of
Counsel to the effect that such action will not cause such REO Property to fail
to qualify as "foreclosure property" within the meaning of Section 860G(a)(8) of
the Code at any time that it is held by the Trust Fund, in which case the
Servicer may take such actions as are specified in such Opinion of Counsel.

     (c)  The Servicer may contract with any Independent Contractor for the
operation and management of any REO Property, provided that:

          (i)  the terms and conditions of any such contract may not be
     inconsistent herewith;

          (ii)  any such contract shall require, or shall be administered to
     require, that (A) the Independent Contractor pay all costs and expenses
     incurred in connection with the operation and management of such REO
     Property, including those listed in subsection (a) 

                                      -60-
<PAGE>
 
     hereof, (B) hold all related revenues in a segregated account, which shall
     be an Eligible Account, and (C) remit all related revenues collected (net
     of such costs and expenses and any fees retained by such Independent
     Contractor) to the Servicer on a monthly or more frequent basis;

          (iii)  none of the provisions of this Section 4.18(c) relating to any
     such contract or to actions taken through any such Independent Contractor
     shall be deemed to relieve the Servicer of any of its duties and
     obligations to the Trustee on behalf of Certificateholders with respect to
     the operation and management of any such REO Property; and

          (iv)  the Servicer shall be obligated with respect thereto to the same
     extent as if it alone were performing all duties and obligations in
     connection with the operation and management of such REO Property.

     The Servicer shall be entitled to enter into any agreement with any
Independent Contractor performing services for it related to its duties and
obligations hereunder for indemnification of the Servicer by such Independent
Contractor, and nothing in this Agreement shall be deemed to limit or modify
such indemnification.  The Servicer shall be entitled to pay all fees owed to
any such Independent Contractor out of the REO Account pursuant to Section 4.17.

     (d)  Subject to Section 4.18(b), the Servicer shall itself be entitled to
operate and manage any foreclosure property and, in such event, shall be
entitled to pay itself a monthly management fee in accordance with Section 4.17;
provided that the amount of such management fee shall not exceed the amount
- --------                                                                   
customarily charged for the operation and management of similar property in the
locality of such REO Property by property managers other than the Servicer or
its Affiliates.

Section 4.19.  Reports to the Securities and Exchange Commission.
               -------------------------------------------------     

     The Servicer shall use reasonable efforts to assist the Contract Seller in
obtaining any information maintained by it in the ordinary course of performing
its duties hereunder that is necessary for the Contract Seller, on behalf of the
Trust Fund, to cause to be filed with the Securities and Exchange Commission any
periodic reports required to be filed under the provisions of the Securities
Exchange Act of 1934, as amended, and the rules and regulations of the
Securities and Exchange Commission thereunder.

Section 4.20.  Annual Statement as to Compliance.
               ---------------------------------     

     The Servicer will deliver to the Contract Seller, the Trustee and each
Rating Agency on or before April 1 of each year, beginning with the first April
1 that occurs after the Cut-off Date, an Officer's Certificate (i) stating that
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) stating that to the best of such officer's knowledge,
based on such review, the Servicer has fulfilled all 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.

 Section 4.21.  Annual Independent Public Accountants' Servicing Report.
                -------------------------------------------------------      

     On or before April 1 of each year, beginning with the first April 1 that
occurs after the Cut-off Date, the Servicer, at its expense, shall cause a firm
of independent public accountants which is a member of the American Institute of
Certified Public Accountants to furnish a statement to the Contract Seller, the
Trustee and each Rating Agency to the effect that such firm has examined certain
documents and records relating to the servicing of the Contracts under this
Agreement and, at the option of the Servicer, manufactured housing installment
sale contracts and installment loan agreements under pooling and servicing
agreements substantially similar to this Agreement with regard to servicing
procedures (such statement to have attached thereto a schedule setting forth the
pooling and servicing agreements covered thereby, including this Agreement) and
that, on the basis of such examination conducted substantially in compliance
with this Agreement or such agreements, as the case may be, and generally
accepted auditing standards, such servicing has been conducted substantially in
compliance with this Agreement or such pooling and servicing agreements, as the
case may be, except for such exceptions as such firm believes to be immaterial
and such other exceptions or errors in records that may be set forth in such
statement.  For purposes of such statement, such firm may assume conclusively
that all pooling and servicing agreements among the Contract Seller, the
Servicer and the Trustee relating to certificates evidencing an interest in
actuarial manufactured housing contracts are substantially similar to one
another, except for any such pooling and servicing agreement which by its terms
specifically states otherwise.

Section 4.22.  Retitling of Land Home Contracts.
               --------------------------------     

     If the Servicer receives actual notice or knowledge that the Servicer is no
longer assigned a long-term senior debt rating from Moody's of Baa3 or higher,
or an equivalent rating from any nationally recognized statistical rating
organization, the Servicer shall promptly provide notice to the Trustee that it
no longer has such rating.  If at any time during the term of this Agreement the
Trustee receives written notice from the Servicer that the Company does not have
a long-term senior debt rating from Moody's of Baa3 or higher, or an equivalent
rating from any nationally recognized statistical rating organization, or if the
Trustee otherwise becomes aware that the Servicer is no longer assigned such
rating, the Trustee, at the Contract Seller's expense, shall file promptly in
the appropriate recording offices the assignments to the Trustee on behalf of
the Trust Fund of each Mortgage securing a Land Home Contract.

                PAYMENTS, MONTHLY ADVANCES AND MONTHLY REPORTS

Section 5.01.          Monthly Advances by the Servicer.
                       --------------------------------     

     (a)  By the close of business on the day prior to each Distribution Date,
the Servicer shall (i) cause to be deposited, out of its own funds, in the
Certificate Account the Monthly Advance for the related Distribution Date, (ii)
direct the Trustee to apply all or a portion of the Excess Contract Payments in
the Certificate Account to make such Monthly Advance, or (iii) do any
combination of clauses (i) and (ii) to make such Monthly Advance.  To the extent
that an Excess Contract Payment (or any portion thereof) that has been applied
pursuant to clause (ii) or (iii) is required for application as to all or a
portion of a scheduled payment due on the related Contract, the Servicer shall
deposit, out of its own funds, the amount of such Excess Contract Payment (or
the portion thereof required for such scheduled payment) into the Certificate
Account on the immediately succeeding Due Date, and the amount so deposited will
become part of the Outstanding Amount Advanced.

     (b)  The Servicer shall reimburse itself for the Outstanding Amount
Advanced out of (i) collections of delinquent payments of principal and interest
on Contracts as to which the Servicer previously made a Monthly Advance, (ii)
available funds in the Certificate Account attributable to Excess Contract
Payments or (iii) any combination of clauses (i) and (ii) above.

     (c)  If the Servicer determines that any advance made pursuant to Section
5.01(a) has become a Nonrecoverable Advance and at the time of such
determination there exists an Outstanding Amount Advanced, then the Servicer
shall reimburse itself out of funds in the Certificate Account for the amount of
such Nonrecoverable Advance (but only if there will not be a shortfall in
respect of principal and interest distributions on the Certificates (other than
the Class R Certificates) for the next succeeding Distribution Date) by
withdrawing such amount pursuant to Section 5.03(v), but not in excess of such
Outstanding Amount Advanced.  If a Contract becomes a Liquidated Contract and at
such time there exists an Outstanding Amount Advanced, then the Servicer shall
reimburse itself out of funds in the Certificate Account for the portion of
Monthly Advances equal to the aggregate of delinquent scheduled payments on such
Contract to the Due Date in the Collection Period in which such Contract became
a Liquidated Contract, but not in excess of such Outstanding Amount Advanced.

Section 5.02.   Payments.
                --------     

     (a)  On each Distribution Date, the Trustee shall withdraw from the
Certificate Account an amount equal to the sum of the Available Distribution
Amount and the Reserve Account Draw Amount, if any, for such Distribution Date
and apply such amount, in the following order of priority, to the distribution
of:

          (i)  to the Senior Certificateholders, the Class A-1 Interest
     Distribution Amount, the Class A-2 Interest Distribution Amount, the Class
     A-3 Interest Distribution Amount, the Class A-4 Interest Distribution
     Amount, the Class A-5 Interest Distribution 

                                      -63-
<PAGE>
 
     Amount, the Class A-6 Interest Distribution Amount, the Class A-7 Interest
     Distribution Amount, the Class A-8 Interest Distribution Amount, the Class
     A-9 Interest
     Distribution Amount and the Class A-IO Interest Distribution concurrently
     to the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6,
     Class A-7, Class A-8, Class A-9 and the Class A-IO Certificateholders,
     respectively; provided that if the Available Distribution Amount, together
                   --------                                                    
     with the Reserve Account Draw Amount, is insufficient to make the full
     distributions of interest referred to in this clause (i), the Available
     Distribution Amount, together with the Reserve Account Draw Amount, shall
     be distributed on such Classes of Certificates pro rata based on such full
     amounts allocable to such Classes;

          (ii)  to the Senior Certificateholders (other than the Class A-IO
     Certificateholders), the Senior Percentage of the Formula Principal
     Distribution Amount in the following order of priority:

               (a)  to the Class A-1 Certificateholders until the Certificate
          Balance of the Class A-1 Certificates is reduced to zero;

               (b)  to the Class A-2 Certificateholders until the Certificate
          Balance of the Class A-2 Certificates is reduced to zero; and

               (c)  to the Class A-3 Certificateholders until the Certificate
          Balance of the Class A-3 Certificates is reduced to zero;

               (d)  to the Class A-4 Certificateholders until the Certificate
          Balance of the Class A-4 Certificates is reduced to zero;

               (e)  to the Class A-5 Certificateholders until the Certificate
          Balance of the Class A-5 Certificates is reduced to zero;

               (f)  to the Class A-6 Certificateholders until the Certificate
          Balance of the Class A-6 Certificates is reduced to zero;

               (g)  to the Class A-7 Certificateholders until the Certificate
          Balance of the Class A-7 Certificates is reduced to zero;

               (h)  to the Class A-8 Certificateholders until the Certificate
          Balance of the Class A-8 Certificates is reduced to zero; and

               (i)  to the Class A-9 Certificateholders until the Certificate
          Balance of the Class A-9 Certificates is reduced to zero;

          (iii)  to the Class  M Certificateholders, the Class M Interest
     Distribution Amount;

          (iv)  to the Class M Certificateholders, the Class M Percentage of the
     Formula Principal Distribution Amount until the Class M Certificate Balance
     is reduced to zero;

                                      -64-
<PAGE>
 
          (v)  to the Class B-1 Certificateholders, the Class B-1 Interest
     Distribution Amount;

          (vi)  to the Class B-1 Certificateholders, the Class B Percentage of
     the Formula Principal Distribution Amount until the Class B-1 Certificate
     Balance is reduced to zero;

          (vii)  to the Class B-2 Certificateholders, the Class B-2 Interest
     Distribution Amount;

          (viii)  to the Class B-2 Certificateholders, the Class B Percentage of
     the Formula Principal Distribution Amount (less any portion thereof
     distributed pursuant to clause (vi) above) until the Class B-2 Certificate
     Balance is reduced to zero;

          (ix)  if such Distribution Date is on or after the earlier of (a) the
     Distribution Date in December 2007 and (b) the first Distribution Date on
     which the percentage equivalent of a fraction, the numerator of which is
     the Pool Scheduled Principal Balance (after giving effect to distributions
     with respect to principal) for such Distribution Date and the denominator
     of which is the Cut-off Date Pool Principal Balance, is less than or equal
     to 25%, to the Reserve Account, any remaining Available Distribution amount
     to the extent necessary to increase the funds in the Reserve Account to the
     Reserve Account Cap;

          (x) if such Distribution Date is on or after December 10, 1998, and
     the Class A-1 Certificate Balance has not been reduced to zero after the
     application of distributions on such Distribution Date to the Class A-1
     Certificateholders pursuant to clause (ii) above, to the Class A-1
     Certificateholders until the Class A-1 Certificate Balance has been reduced
     to zero; and

          (xi)  to the Class R Certificateholders, any remaining Available
     Distribution Amount.

     Notwithstanding the foregoing, on any Distribution Date on which the Class
M Certificate Balance has not been reduced to zero and the amount distributable
(the "initial distribution") to holders of the Class B-2 Certificates pursuant
to clause (viii) above would cause (x) the sum of (i) the Class B-2 Certificate
Balance and (ii) the amount on deposit in the Reserve Account (in each case,
after giving effect to the initial distribution) (such sum, the "Clause X
Amount") to be less than (y) $9,999,998 (the "Clause Y Amount"), which is 2% of
the Cut-off Date Pool Principal Balance, then the distribution to holders of the
Class B-2 Certificates pursuant to clause (viii) above will be reduced to such
amount as will cause the Clause X Amount to equal, as nearly as possible, the
Clause Y Amount, and the Available Distribution Amount that remains after such
reduced distribution to the Class B-2 Certificateholders will be distributed on
account of principal pro rata to holders of the Senior Certificates and the
Class M Certificates on the basis of their Certificate Balances to the extent
necessary to reduce such Certificate Balances to zero.

     In addition, notwithstanding the prioritization of the distribution of the
Formula Principal Distribution Amount to the Holders of the Senior Certificates
pursuant to clause (ii) above, on a Distribution Date, if any, in respect of
which a Deficiency Event is in effect, the portion of the 

                                      -65-
<PAGE>
 
Formula Principal Distribution Amount for such Distribution Date that would
otherwise be distributed sequentially to the Class A-1, Class A-2, Class A-3,
Class A-4, Class A-5, Class A-6, Class A-7, Class A-8 and Class A-9
Certificateholders pursuant to clause (ii) above will instead be distributed to
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7,
Class A-8 and Class A-9 Certificateholders pro rata based upon the Certificate
Balance of each such Class until the Certificate Balances of the Class A-1,
Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8 and
Class A-9 Certificates have been reduced to zero. A "Deficiency Event" will be
in effect for any Distribution Date as to which the Pool Scheduled Principal
Balance is equal to or less than the aggregate of the Certificate Balances of
the Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7,
Class A-8 and Class A-9 Certificates.

     Furthermore, notwithstanding the foregoing, if the percentage of the
Formula Principal Distribution Amount allocable to the Holders of the Class A-9
Certificates on any Distribution Date pursuant to clause (ii) above exceeds the
Class A-9 Certificate Balance for such Distribution Date, such excess will be
distributed to the Class M and Class B-1 Certificateholders (or the Class B-2
Certificateholders if the Class B-1 Certificate Balance has been reduced to
zero) on the basis of the Class M and Class B Percentages, respectively.  If the
percentage of the Formula Principal Distribution Amount allocable to the Class M
Certificateholders on any Distribution Date pursuant to clause (iv) above
exceeds the Class M Certificate Balance for any such Distribution Date, such
excess will be distributed to the Class B-1 Certificateholders until the Class
B-1 Certificate Balance is reduced to zero (and to the Class B-2
Certificateholders thereafter until the Class B-2 Certificate Balance is reduced
to zero).  The Class A-IO Notional Principal Amount is only for convenience in
certain calculations.  The Class A-IO Certificateholders do not have the right
to receive distributions allocable to principal hereunder.

     Such distributions to the Class A-1 Certificateholders, Class A-2
Certificateholders, Class A-3 Certificateholders, Class A-4 Certificateholders,
Class A-5 Certificateholders, Class A-6 Certificateholders, Class A-7
Certificateholders, Class A-8 Certificateholders, Class A-9 Certificateholders,
Class A-IO Certificateholders, Class M Certificateholders, Class B-1
Certificateholders and Class B-2 Certificateholders shall be made such that the
Trustee shall distribute (a) to each Class A-1 Certificateholder as of the
preceding Record Date an amount equal to the product of the aggregate Percentage
Interest evidenced by such Certificateholder's Class A-1 Certificates and the
Class A-1 Distribution Amount for such Distribution Date, (b) to each Class A-2
Certificateholder as of the preceding Record Date an amount equal to the product
of the aggregate Percentage Interest evidenced by such Certificateholder's Class
A-2 Certificates and the Class A-2 Distribution Amount for such Distribution
Date, (c) to each Class A-3 Certificateholder as of the preceding Record Date an
amount equal to the product of the aggregate Percentage Interest evidenced by
such Certificateholder's Class A-3 Certificates and the Class A-3 Distribution
Amount for such Distribution Date, (d) to each Class A-4 Certificateholder as of
the preceding Record Date an amount equal to the product of the aggregate
Percentage Interest evidenced by such Certificateholder's Class A-4 Certificates
and the Class A-4 Distribution Amount for such Distribution Date, (e) to each
Class A-5 Certificateholder as of the preceding Record Date an amount equal to
the product of the aggregate Percentage Interest evidenced by such
Certificateholder's Class A-5 Certificates and the Class A-5 Distribution Amount
for such Distribution Date, (f) to each Class A-6

Certificateholder as of the preceding Record Date an amount equal to the product
of the aggregate Percentage Interest evidenced by such Certificateholder's Class

amount equal to the product of the aggregate Percentage Interest evidenced by
such Certificateholder's Class A-7 Certificates and the Class A-7 Distribution
Amount for such Distribution Date, (h) to each Class A-8 Certificateholder as of
the preceding Record Date an amount equal to the product of the aggregate
Percentage Interest evidenced by such Certificateholder's Class A-8 Certificates
and the Class A-8 Distribution Amount for such Distribution Date, (i) to each
Class A-9 Certificateholder as of the preceding Record Date an amount equal to
the product of the aggregate Percentage Interest evidenced by such
Certificateholder's Class A-9 Certificates and the Class A-9 Distribution Amount
for such Distribution Date, (j) to each Class A-IO Certificateholder as of the
preceding Record Date an amount equal to the product of the aggregate Percentage
Interest evidenced by such Certificateholder's Class A-IO Certificates and the
Class A-IO Distribution Amount for such Distribution Date, (k) to each Class M
Certificateholder as of the preceding Record Date an amount equal to the product
of the aggregate Percentage Interest evidenced by such Certificateholder's Class
M Certificates and the Class M Distribution Amount, (l) to each Class B-1
Certificateholder as of the preceding Record Date an amount equal to the product
of the aggregate Percentage Interest evidenced by such Certificateholder's Class
B-1 Certificates and the Class B-1 Distribution Amount for such Distribution
Date and (m) to each Class B-2 Certificateholder as of the preceding Record Date
an amount equal to the product of the aggregate Percentage Interest evidenced by
such Certificateholder's Class B-2 Certificates and the Class B-2 Distribution
Amount for such Distribution Date. The Trustee shall pay each Certificateholder
of record by check mailed to such Certificateholder at the address for such
Certificateholder appearing on the Certificate Register; provided that if such
                                                         --------
Certificateholder holds Certificates evidencing a Percentage Interest
aggregating 10% or more with respect to such Class and has given the Trustee
appropriate written instructions at least 10 days prior to the related
Distribution Date (which instructions, until revised, shall remain operative for
all Distribution Dates thereafter), the Trustee shall pay such Certificateholder
by wire transfer of funds. If on any Determination Date the Servicer determines
that there are no Contracts outstanding and no other funds or assets in the
Trust Fund other than the funds in the Certificate Account, the Servicer
promptly shall instruct the Trustee to send the final distribution notice to
each Certificateholder and make provision for the final distribution in
accordance with Section 10.01(c). Final payment of any Certificate shall be made
only upon presentation of such Certificate at the office or agency of the
Certificate Registrar.

     (b)  On each Distribution Date, the Trustee shall withdraw from the
Certificate Account (solely out of the Available Distribution Amount for such
Distribution Date after giving effect to the distributions made to the
Certificateholders pursuant to Section 5.02(a)(i)-(viii) and to the Reserve
Account pursuant to Section 5.02(a)(ix) on such Distribution Date) and
distribute the amount specified in Section 5.02(a)(x) for such Distribution Date
to the Class R Certificateholders by wire transfer of immediately available
funds.  Such distribution shall be made by a means that is mutually acceptable
to the Trustee and the Class R Certificateholders.

     (c)  Each distribution with respect to a Global Certificate shall be paid
to the Depository, which shall credit the amount of such distribution to the
accounts of its Depository

Participants in accordance with its normal procedures. Each Depository
Participant shall be responsible for disbursing such distribution to the
Certificate Owners that it represents and to each indirect participating
brokerage firm (a "brokerage firm" or "indirect participating firm") for which
it acts as agent. Each brokerage firm shall be responsible for disbursing funds
to the Certificate Owners that it represents. All such credits and disbursements
with respect to a Global Certificate are to be made by the Depository and the
Depository Participants in accordance with the provisions of the Certificates.
Neither the Trustee, the Certificate Registrar, the Contract Seller nor the
Servicer shall have any responsibility therefor. To the extent applicable and
not contrary to the rules of the Depository, the Trustee shall comply with the
provisions of the forms of the Certificates as set forth in Exhibit B-1, Exhibit

     The Servicer may, from time to time as provided herein, make withdrawals
from the Certificate Account of amounts deposited therein pursuant to Section
4.05 that are attributable to the Contracts for the following purposes:

          (i)  to pay to the Contract Seller with respect to each Contract sold
     by it or property acquired in respect thereof that has been repurchased or
     replaced pursuant to Section 3.05, all amounts received thereon that are
     specified in such Section to be property of the Contract Seller;

On each Distribution Date, the Servicer shall forward or cause to be forwarded

     The Class R Certificate shall initially be issued with no principal
balance.

     The Certificates shall be executed by manual or facsimile signature on
behalf of the Trustee by an authorized officer.  Certificates bearing the manual
or facsimile signatures of individuals who were, at the time when such
signatures were affixed, authorized to sign on behalf of the Trustee shall bind
the Trustee, notwithstanding that such individuals or any of them have ceased to
be so authorized prior to the authentication and delivery of such Certificates
or did not hold such offices at the date of such authentication and delivery. 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 set forth as attached hereto executed
by the Trustee by manual signature, and such certificate of authentication upon
any Certificate shall be conclusive evidence, and the only evidence, that such
Certificate has been duly authenticated and delivered hereunder.  All
Certificates shall be dated the date of their authentication.  On the Closing
Date, the Trustee shall authenticate the Certificates to be issued at the
written direction of the Contract Seller or any Affiliate thereof.

     The Contract Seller shall provide, or cause to be provided, to the Trustee
on a continuous basis, an adequate inventory of Certificates to facilitate
transfers.

Section 6.02.  Certificate Register; Registration of Transfer and Exchange of
               --------------------------------------------------------------
               Certificates.
               ------------     

     (a)  The Trustee shall maintain, or cause to be  maintained, a Certificate
Register for the Trust Fund in which, subject to the provisions of subsections
(b) and (c) below and to such reasonable regulations as it may prescribe, the
Trustee shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided.  Upon surrender for registration
of transfer of any Certificate, the Trustee shall authenticate and deliver, in
the name of the designated transferee or transferees, one or more new
Certificates of the same Class and of like aggregate Percentage Interest.

     At the option of a Certificateholder, Certificates may be exchanged for
other Certificates of the same Class in authorized denominations and evidencing
the same aggregate Percentage Interest upon surrender of the Certificates to be
exchanged at the office or agency of the Trustee. Whenever any Certificates are
so surrendered for exchange, the Trustee shall execute, authenticate, and
deliver the Certificates that the Certificateholder making the exchange is
entitled to receive.  Every Certificate presented or surrendered for
registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to the Trustee duly executed by the
holder thereof or his attorney duly authorized in writing.

     No service charge to the Certificateholders shall be made for any
registration of transfer or exchange of Certificates, but payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of Certificates may be required.

     All Certificates surrendered for registration of transfer or exchange shall
be canceled and subsequently destroyed by the Trustee in accordance with the
Trustee's customary procedures.

     (b)  No Transfer of a Private Certificate shall be made unless such
Transfer is made pursuant to an effective registration statement under the
Securities Act and any applicable state 

                                      -84-

securities laws or is exempt from the registration requirements under the
Securities Act and such state securities laws. In the event that a Transfer is
to be made in reliance upon an exemption from the Securities Act and such laws,
in order to assure compliance with the Securities Act and such laws, the
Certificateholder desiring to effect such Transfer and such Certificateholder's
prospective transferee, at no expense to the Trustee, the Contract Seller or the
Servicer, shall be required to provide to the Trustee, the Contract Seller and
the Servicer, an investment letter substantially the forms set forth in Exhibit
                                                                        -------
H (the "Transferor Certificate"), respect to the Class B-2 Certificates, and
- -
either Exhibit J (the Letter") or Exhibit K (the "Rule 144A Letter") or as
       ---------                  ---------
otherwise to the Contract Seller. In the event that such a Transfer is to be
made within two years from the date of the initial issuance of Certificates
pursuant hereto (other than a Transfer as to which the proposed transferee has
provided a Rule 144A Letter), there shall also be delivered to the Trustee, the
Contract Seller and the Servicer an Opinion of Counsel that such Transfer may be
made pursuant to an exemption from the Securities Act and such state securities
laws, which Opinion of Counsel shall not be an expense of the Contract Seller,
the Servicer or the Trustee. The Contract Seller shall provide to any Holder of
Private Certificate and any prospective transferee designated by any such
Holder, information regarding the Certificates and the Contracts and such other
information as shall be necessary to satisfy the condition to eligibility set
forth in Rule 144A(d)(4) for Transfer of any Private Certificate without
registration thereof under the Securities Act pursuant to the registration
exemption provided by Rule 144A. The Trustee and the Servicer shall cooperate
with the Contract Seller in providing the Rule 144A information referenced in
the preceding sentence, including providing to the Contract Seller such
information regarding the Certificates, the Contracts and other matters
regarding the Trust Fund as the Contract Seller shall reasonably request to meet
its obligation under the preceding sentence. Each Holder of a Private
Certificate desiring to effect such Transfer shall, and does hereby agree to,
indemnify the Trustee, the Contract Seller and the Servicer against any
liability that may result if the Transfer is not so exempt or is not made in
accordance with such federal and state laws.

     No transfer of an ERISA Restricted Certificate will be made unless the
Trustee has received either (i) an Opinion of Counsel, at no expense to the
Trustee, the Contract Seller or the Servicer, acceptable to and in form and
substance satisfactory to the Trustee, the Contract Seller and the Servicer with
respect to the permissibility of such transfer under ERISA and Section 4975 of
the Code and stating, among other things, that the transferee's acquisition of
such ERISA Restricted Certificate will not constitute or result in a non-exempt
prohibited transaction under Section 406 of ERISA or Section 4975 of the Code
and will not subject the Servicer, the Contract Seller or the Trustee to any
obligation or liability in addition to those undertaken in this Agreement or
(ii) a representation letter from the transferee, substantially in the form of
paragraph 5 of Exhibit G (as to the Class R Certificates) or Exhibit J or
Exhibit K (as to the Class M, Class B-1 or Class B-2 Certificates).

     (c)  (i)  Each Person who has or who acquires any Ownership Interest in a
Class R 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 or its designee 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 

                                      -85-
<PAGE>
 
rights of each Person acquiring any Ownership Interest in a Class R Certificate
are expressly subject to the following provisions:

         (A)  Each Person holding or acquiring any Ownership Interest in a Class
     R shall be a Permitted Transferee and shall promptly notify 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 Class R Certificate, the Trustee shall require delivery to it, and
     shall not register the Transfer of any Class R Certificate until its
     receipt of, (I) an affidavit and (a "Transfer Affidavit," in the form
     attached hereto as Exhibit G-1) from the proposed Transferee, representing
     and warranting, among other things, that it is a Permitted Transferee, that
     it is not acquiring its Ownership Interest in the Class R 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 Class R Certificate, it will endeavor
     to remain a Permitted Transferee, and that it has reviewed the provisions
     of this Section 6.02(c) and agrees to be bound by them, and (II) a
     certificate, in the form attached hereto as Exhibit G-2, from the Holder
     wishing to transfer the Class R Certificate, representing and warranting,
     among other things, that no purpose of the proposed Transfer is to impede
     the assessment or collection of tax.

         (C) Notwithstanding the delivery of a Transfer Affidavit by a proposed
     Transferee under clause (B) above, if a Responsible Officer of the Trustee
     who is assigned to this Agreement has actual knowledge that the proposed
     Transferee is not a Permitted Transferee, no Transfer of an Ownership
     Interest in a Class R Certificate to such proposed Transferee shall be
     effected.

         (D) Each Person holding or acquiring any Ownership Interest in a Class
     R Certificate shall agree (x) to require a Transfer Affidavit from any
     other Person to whom such Person attempts to transfer its Ownership
     Interest in a Class R Certificate and (y) not to transfer its Ownership
     Interest unless it provides a certificate to the Trustee in the form
     attached hereto as Exhibit G-2.

         (E) Each Person holding or acquiring an Ownership Interest in a Class R
     Certificate, by purchasing an Ownership Interest in such Certificate,
     agrees to give the Trustee written notice that it is a "pass-through
     interest holder" within the meaning of Temporary Treasury Regulations
     Section 1.67-3T(a)(2)(i)(A) immediately upon acquiring an Ownership
     Interest in a Class R Certificate, if it is, or is holding an Ownership
     Interest in a Class R Certificate on behalf of, a "pass-through interest
     holder."

          (ii) The Trustee will register the Transfer of any Class R Certificate
only if it shall have received the Transfer Affidavit, a certificate of the
Holder requesting such transfer in the form attached hereto as Exhibit G-2.
Transfers of the Class R Certificates to Non-United States Persons and
Disqualified Organizations (as defined in Section 860E(e)(5) of the Code) are
prohibited.

                                      -86-
<PAGE>
 
          (iii)  (A)    If any Disqualified Organization shall become a
holder of a Class R 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 Class R Certificate.  If a Non-United States Person shall become a holder
of a Class R Certificate, then the last preceding United States Person shall be
restored, to the extent permitted by law, to all rights and obligations as
Holder thereof retroactive to the date of registration of such transfer of such
Class R Certificate.  If a transfer of a Class R 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 Class R
Certificate. The Trustee shall be under no liability to any Person for any
registration of Transfer of a Class R Certificate that is in fact not permitted
by this Section 6.02(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 a Class R
Certificate in violation of the restrictions in this Section 6.02(c) and to the
extent that the retroactive restoration of the rights of the Holder of such
Class R Certificate as described in clause (iii)(A) above shall be invalid,
illegal or unenforceable, then either the Servicer shall have the right, without
notice to the holder or any prior holder of such Class R Certificate, to sell
such Class R Certificate to a purchaser selected by the Servicer on such terms
as the Servicer may choose. Such purported Transferee shall promptly endorse and
deliver each Class R Certificate in accordance with the instructions of the
Servicer. Such purchaser may be the Servicer itself or any Affiliate of the
Servicer. The proceeds of such sale, net of the commissions (which may include
commissions payable to the Servicer or its Affiliates), expenses and taxes due,
if any, will be remitted by the Servicer 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 Servicer, and the Servicer shall not be liable to any
Person having an Ownership Interest in a Class R Certificate as a result of its
exercise of such discretion.

          (iv)   The Servicer, on behalf of the Trustee, shall use its
reasonable efforts to make available, upon written request from the Trustee, all
information necessary to compute any tax imposed (A) as a result of the Transfer
of an Ownership Interest in a Class R Certificate to any Person who is a
Disqualified Organization, including the information regarding "excess
inclusions" of such Class R Certificates required to be provided to the Internal
Revenue Service and certain Persons as described in Treasury Regulations
Sections 1.860D-1(b)(5) and 1.860E-2(a)(5), and (B) as a result of any regulated
investment company, real estate investment trust, common trust fund,
partnership, trust, estate or organization described in Section 1381 of the Code
that holds an Ownership Interest in a Class R Certificate having as among its
record holders at any time any Person who is a Disqualified Organization.
Reasonable compensation for providing such information may be required by the
Servicer from such Person.

          (v)    The provisions of this Section 6.02(c) set forth prior to this
clause (v) may be modified, added to or eliminated pursuant to Section 11.01,
provided that there shall have also been delivered to the Trustee the following:

                                      -87-
<PAGE>
 
          (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, if any, of
     any Class of the Class A, Class M or Class B below the lower of the then-
     current rating or the rating assigned to such Certificates as of the
     Closing Date by such Rating Agency; and

          (B) a certificate of the Servicer stating that the Servicer has
     received an Opinion of Counsel, in form and substance satisfactory to the
     Servicer, to the effect that such modification, addition to or absence of
     such provisions will not cause Trust Fund to cease to qualify as a REMIC
     and will not cause (x) the Trust Fund to be subject to an entity-level tax
     caused by the Transfer of any Class R Certificate to a Person that is a
     Disqualified Organization or (y) a Certificateholder or another Person to
     be subject to a REMIC-related tax caused by the Transfer of a Class R
     Certificate to a Person that is not a Permitted Transferee.

     (d) The preparation and delivery of all certificates and opinions referred
to above in this Section 6.02 shall not be an expense of the Trust Fund, the
Trustee, the Contract Seller or the Servicer.

Section 6.03.   Mutilated, Destroyed, Lost or Stolen Certificates
                -------------------------------------------------     

     If (a) any mutilated Certificate is surrendered to the Trustee, or the
Trustee receives evidence to its satisfaction of the destruction, loss or theft
of any Certificate and of the ownership thereof and (b) there is delivered to
the Trustee and the Certificate Administrator, if any, 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 that such Certificate has been acquired by a
bona fide purchaser, the Trustee shall execute, authenticate and deliver, in
exchange for or in lieu of any such mutilated, destroyed, lost or stolen
Certificate, a new Certificate of like Class, tenor and Percentage Interest.  In
connection with the issuance of any new Certificate under this Section 6.03, the
Trustee may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
Any replacement Certificate issued pursuant to this Section 6.03 shall
constitute complete and indefeasible evidence of ownership in the Trust Fund, as
if originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.  All Certificates surrendered to the Trustee under
the terms of this Section 6.03 shall be canceled and destroyed by the Trustee in
accordance with its standard procedures without liability on its part.

Section 6.04.   Persons Deemed Owners
                ---------------------     

     The Servicer, the Trustee and any agent of the Servicer or the Trustee may
treat the person in whose name any Certificate is registered as the owner of
such Certificate for the purpose of receiving distributions as provided in this
Agreement and for all other purposes whatsoever, and neither the Servicer, the
Trustee nor any agent of the Servicer or the Trustee shall be affected by any
notice to the contrary.

Section 6.05.   Access to List of Certificateholders' Names and Addresses
                ---------------------------------------------------------      

     If three or more Certificateholders (a) request such information in writing
from the Trustee, (b) state that such Certificateholders desire to communicate
with other Certificateholders with respect to their rights under this Agreement
or under the Certificates, and (c) provide a copy of the communication that such
Certificateholders propose to transmit or if the Contract Seller or Servicer
shall request such information in writing from the Trustee, then the Trustee
shall, within ten Business Days after the receipt of such request, provide the
Contract Seller, the Servicer or such Certificateholders at such recipients'
expense the most recent list of the Certificateholders of the Trust Fund held by
the Trustee, if any.  The Contract Seller and every Certificateholder, by
receiving and holding a Certificate, agree that the Trustee shall not be held
accountable by reason of the disclosure of any such information as to the list
of the Certificateholders hereunder, regardless of the source from which such
information was derived.

Section 6.06.   Global Certificates
                -------------------     

     The Class A-1, Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class
A-7, Class A-8, Class A-9, Class A-IO, Class M and Class B-1 Certificates, upon
original issuance, shall be issued in the form of one or more typewritten
Certificates representing the Global Certificates, to be delivered to the
Depository by or on behalf of the Contract Seller.  Such Global Certificates
shall initially be registered on the Certificate Register in the name of the
Depository or its nominee, and no Certificate Owner will receive a definitive
certificate representing such Certificate Owner's interest in such Certificates,
except as provided in Section 6.08.  Unless and until definitive, fully
registered Certificates ("Definitive Certificates") have been issued to the
Certificate Owners of such Certificates pursuant to Section 6.08:

     (a) the provisions of this Section shall be in full force and effect;

     (b) Either Contract Seller, the Servicer and the Trustee may treat the
Depository and the Depository Participants for all purposes as the authorized
representative of the respective Certificate Owners of such Certificates and, in
the case of distributions, with the Depository as the authorized representative
of the Depository Participants and the Certificate Owners;

     (c) registration of the Global Certificates may not be transferred by the
Trustee except to another Depository;

     (d) the rights of the respective Certificate Owners of such Certificates
shall be exercised only through the Depository and the Depository Participants
and shall be limited to those established by law and agreements between the
Owners of such Certificates and the Depository and/or the Depository
Participants. Pursuant to the Depository Agreement, unless and until Definitive
Certificates are issued with respect to the Class A-1, Class A-2, Class A-3,
Class A-4, Class A-5, Class A-6, Class A-7, Class A-8, Class A-9, Class A-IO,
Class M and Class B-1 Certificates pursuant to Section 6.08, the Depository will
make book-entry transfers among the Depository Participants and receive and
transmit distributions of principal and interest on the related Certificates to
such Depository Participants;

                                      -89-
<PAGE>
 
     (e) the Depository may collect its usual and customary fees, charges and
expenses from its Depository Participants;

     (f) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants; and

     (g) to the extent that the provisions of this Section conflict with any
other provisions of this Agreement, the provisions of this Section shall
control.

     For purposes of any provision of this Agreement requiring or permitting
actions with the consent of, or at the direction of, Certificateholders
evidencing a specified percentage of the Certificate Balance of a Class of
Certificates, such direction or consent may be given by Certificate Owners
(acting through the Depository and the Depository Participants) owning Global
Certificates evidencing the requisite percentage of the Certificate Balance or
Class A-IO Notional Principal Amount of such Class of Certificates, as
applicable,  or the requisite Percentage Interests.

Section 6.07.   Notices to Depository
                ---------------------     

     Whenever any notice or other communication is required to be given to
Certificateholders of any Class with respect to which Global Certificates have
been issued, unless and until Definitive Certificates shall have been issued to
the related Certificate Owners, the Trustee shall give all such notices and
communications to the Depository.

Section 6.08.   Definitive Certificates
                -----------------------     

     If, after Global Certificates have been issued with respect to Class A-1,
Class A-2, Class A-3, Class A-4, Class A-5, Class A-6, Class A-7, Class A-8,
Class A-9, Class A-IO, Class M and Class B-1 Certificates, (a) the Servicer
advises the Trustee that the Depository is no longer willing or able to
discharge properly its responsibilities under the Depository Agreement with
respect to such Certificates and the Trustee or the Contract Seller is unable to
locate a qualified successor, (b) the Contract Seller, at their sole option,
advise the Trustee that they elect to terminate the book-entry system with
respect to such Certificates through the Depository or (c) after the occurrence
and continuation of an Event of Default, Certificate Owners of such Global
Certificates having not less than 51% of the Voting Rights evidenced by the
related Class advise the Trustee and the Depository in writing through the
Depository Participants that the continuation of a book-entry system with
respect to such Certificates through the Depository (or its successor) is no
longer in the best interests of the Certificate Owners with respect to such
Certificates, then the Trustee shall notify all Certificate Owners of such Class
of Certificates, through the Depository, of the occurrence of any such event and
of the availability of Definitive Certificates for such Class to Certificate
Owners requesting the same. The Contract Seller shall provide the Trustee with
an adequate inventory of certificates to facilitate the issuance and transfer of
Definitive Certificates. Upon surrender to the Trustee of any such Certificates
by the Depository, accompanied by registration instructions from the Depository
for registration, the Trustee shall authenticate and deliver such Definitive
Certificates. Neither the Contract Seller nor the Trustee shall be liable for
any delay in delivery of such instructions and each may conclusively rely on,
and shall be protected in relying on, such instructions. Upon the issuance of
such

                                      -90-
<PAGE>
 
Definitive Certificates, all references herein to obligations imposed upon or to
be performed by the Depository shall be deemed to be imposed upon and performed
by the Trustee, to the extent applicable with respect to such Definitive
Certificates and the Trustee shall recognize the Holders of such Definitive
Certificates as Certificateholders hereunder.

                    THE CONTRACT SELLER AND THE SERVICER

Section 7.01.   Liabilities to Obligors.
                -----------------------     

     No liability to any Obligor under any of the Contracts arising out of any
act or omission to act of the Servicer in servicing the Contracts prior to the
Closing Date is intended to be assumed by the Contract Seller, the Trustee, the
Certificate Administrator or the Certificateholders under or as a result of this
Agreement and the transactions contemplated hereby and, to the maximum extent
permitted and valid under mandatory provisions of law, the Contract Seller, the
Trustee, the Certificate Administrator and the Certificateholders expressly
disclaim such assumption.

Section 7.02.   Servicer's Indemnities.
                ----------------------      

     The Servicer shall defend and indemnify the Trust Fund, the Trustee, the
Certificate Administrator, the Certificate Registrar, the Paying Agent, the
Contract Seller and the Certificateholders against any and all costs, expenses,
losses, damages, claims or liabilities, including reasonable fees and expenses
of counsel and expenses of litigation, arising from third party claims or
actions (including penalties or fees imposed by any governmental or regulatory
body or agency) in respect of any action taken by the Servicer with respect to
any Contract or Manufactured Home constituting a failure by the Servicer to
perform its obligations under this Agreement. This indemnity shall survive any
Event of Default (but a Servicer's obligations under this Section 7.02 shall not
relate to any actions of any subsequent Servicer after an Event of Default) and
any payment of the amount owing under, or any repurchase by the Contract Seller
of, any such Contract.

Section 7.03.   Operation of Indemnities.
                ------------------------     

     Indemnification under this Article VII shall include reasonable fees and
expenses of counsel and expenses of litigation. Any amounts received by the
Trustee from the Servicer pursuant to this Article VII shall be deposited in the
Certificate Account pursuant to Section 4.05. If the Servicer has made any
indemnity payments to the Trustee pursuant to this Article VII and the Trustee
thereafter collects any of such amounts from others, the Trustee will repay such
amounts collected to the Servicer, together with any interest collected thereon.

Section 7.04.   Merger or Consolidation of the Contract Seller or the Servicer.
                --------------------------------------------------------------

     The Contract Seller and the Servicer will each keep in full effect their
existence, rights and franchises as a national banking association or federal
savings bank, as the case may be, and will obtain and preserve its qualification
to do business as a foreign corporation in each jurisdiction in which such
qualification is or shall be necessary to protect the validity and
enforceability of this Agreement, the Certificates or any of the Contracts and
to perform its duties under this Agreement.

     Any Person into which the Contract Seller or the Servicer may be merged or
consolidated, or any corporation or association resulting from any merger,
conversion or consolidation to which 

                                      -92-
<PAGE>
 
the Contract Seller or the Servicer shall be a party, or any Person succeeding
to the business of the Contract Seller or the Servicer, shall be the successor
of the Contract Seller or the Servicer hereunder, without the execution or
filing of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding; provided, however, that the
                                                 --------  -------
successor or surviving Person to the Servicer shall satisfy the requirements of

The Contract Seller and the Servicer shall promptly notify each Rating Agency of
any such merger to which it is a party.

Section 7.05.   Limitation on Liability of the Contract Seller, the Servicer and
                ----------------------------------------------------------------
                Others.
                ------     

     Neither the Contract Seller, the Servicer nor any of their directors,
officers, employees or agents shall be under any liability to the Trustee or the
Certificateholders for any errors in judgment or any action taken or for
refraining from the taking of any action, pursuant to this Agreement; provided,
                                                                      -------- 
however, that this provision shall not protect the Contract Seller or any such
- -------                                                                       
Person against any liability that would otherwise be imposed by reason of its
willful misconduct, or gross negligence; provided, further that this provision
                                         --------  -------                    
shall not protect the Servicer or any such Person against any liability that
would otherwise be imposed by reason of its willful misconduct or gross
negligence. The Contract Seller, the Servicer and any of their directors,
officers, employees or agents may rely on any document of any kind prima facie
properly executed and submitted by any Person respecting any matters arising
hereunder. Neither the Contract Seller nor the Servicer shall be under any
obligation to appear in, prosecute or defend any legal action which arises under
this Agreement (other than in connection with the enforcement of any Contract in
accordance with this Agreement) and which in its opinion may involve it in any
expenses or liability; provided, however, that the Servicer may in its
                       --------  -------                              
discretion undertake any such other legal action which it may deem necessary or
desirable in respect to this Agreement and the rights and duties of the parties
hereto. In such event, the legal expenses and costs of such other legal action
and any liability resulting therefrom shall be expenses, costs and liabilities
payable from the Certificate Account, and the Servicer shall be entitled to be
reimbursed therefor out of the Certificate Account as provided by Section 5.03.

Section 7.06.   Assignment by Servicer.
                ----------------------     

     The Servicer may, with the prior written consent of the Contract Seller,
which consent shall not be unreasonably withheld, assign its rights and delegate
its duties and obligations under this Agreement; provided that the Person
                                                 --------                
accepting such assignment or delegation shall be a Person which is satisfactory
to the Trustee and the Contract Seller, in their respective sole judgment, shall
be willing to service the Contracts, and shall execute and deliver to the
Contract Seller and the Trustee an agreement, in form and substance reasonably
satisfactory to the Contract Seller and the Trustee, which contains an
assumption by such Person of the due and punctual performance and observance of
each covenant and condition to be performed or observed by the Servicer under
this Agreement; and further provided that each Rating Agency's rating of any
                    ------- --------                                        
Class of the Certificates in effect immediately prior to such assignment and
delegation will not be withdrawn or reduced as a result of such assignment and
delegation, as evidenced by a letter from each Rating Agency. In the case of any
such assignment and delegation, the Servicer shall be released from its
obligations under this Agreement, except that the Servicer shall remain liable
for all liabilities and obligations incurred by it as Servicer 

                                      -93-
<PAGE>
 
hereunder prior to the satisfaction of the conditions to such assignment and
delegation set forth in the next preceding sentence.

Section 7.07.   Successor to the Servicer.
                -------------------------     

     In connection with the termination of the Servicer's responsibilities and
duties under this Agreement pursuant to Section 8.01, the Trustee shall (i)
succeed to and assume all of the Servicer's responsibilities, rights, duties and
obligations under this Agreement (except the duty to pay and indemnify the
Trustee pursuant to Section 9.05 hereof), or (ii) with the consent of the
Contract Seller, which consent shall not be unreasonably withheld, appoint a
successor which shall have a net worth of not less than $50,000,000 and shall
have serviced for at least one year prior to such appointment a portfolio of not
less than $100,000,000 principal balance of manufactured housing installment
sale contracts or installment loans and which shall succeed to all rights and
assume all of the responsibilities, duties and liabilities of the Servicer under
this Agreement prior to the termination of the Servicer's responsibilities,
duties and liabilities under this Agreement (except that the duty to pay and
indemnify the Trustee pursuant to Section 9.05 hereof shall be subject to
negotiation at the time of such appointment). If the Trustee has become the
successor to the Servicer in accordance with this Section 7.07, the Trustee may,
if it shall be unwilling to continue to so act, or shall, if it is unable to so
act, appoint, or petition a court of competent jurisdiction to appoint, a
successor satisfying the requirements set out in clause (ii) above. In
connection with any appointment of a successor Servicer, the Trustee may make
such arrangements for the compensation of such successor out of payments on
Contracts as it and such successor shall agree or such court shall determine;
provided, however, that the Monthly Servicing Fee shall not be in excess of a
- --------  -------                                                            
monthly amount equal to 1/12th of the product of 1% and the Pool Scheduled
Principal Balance for the Distribution Date in respect of which such
compensation is being paid without the consent of all of the Certificateholders
and notice to each Rating Agency. If the Servicer's duties, responsibilities and
liabilities under this Agreement should be terminated pursuant to Section 7.06
or 8.01, the 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, shall cooperate with the Trustee
and any successor Servicer in effecting the termination of the Servicer's
responsibilities and rights hereunder, and shall take no action whatsoever that
might impair or prejudice the rights or financial condition of its successor.
The assignment by a Servicer pursuant to Section 7.06 or removal of Servicer
pursuant to Section 8.01 shall not become effective until a successor shall be
appointed pursuant to this Section 7.07 and shall in no event relieve the
Contract Seller of liability pursuant to Section 3.05 for breach of the
representations and warranties made pursuant to Section 3.02 or 3.03. The
Servicer being terminated pursuant to Section 8.01 or Section 7.06 shall bear
all costs of a transfer of servicing therefrom, including but not limited to
those of the Trustee reasonably allocable to specific employees and overhead,
legal fees and expenses, and costs of amending the Agreement, if necessary.

     Any successor appointed as provided herein shall execute, acknowledge and
deliver to the Servicer and to the Trustee an instrument accepting such
appointment, whereupon such successor shall become fully vested with all the
rights, powers, duties, responsibilities, obligations and liabilities of the
Servicer, with like effect as if originally named as a party to this Agreement
and 

                                      -94-
<PAGE>
 
the Certificates. Any assignment by or termination of the Servicer pursuant
to Section 7.06 or 8.01 or the termination of this Agreement pursuant to Section
10.01 shall not affect any claims that the Trustee may have against the Servicer
arising prior to any such termination or resignation.

     The Servicer shall timely deliver to the successor the funds in the
Certificate Account and REO Account and all Contract Files, Land Home Contract
Files and related documents and statements held by it hereunder and the Servicer
shall account for all funds and shall execute and deliver such instruments and
do such other things as reasonably may be required to more fully and definitely
vest and confirm in the successor all such rights, powers, duties,
responsibilities, obligations and liabilities of the Servicer. Without
limitation, the Trustee is 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 (including transfer instruments in respect of certificates
of title and financing statements relating to the Manufactured Homes), and to do
any and all acts or things necessary or appropriate to effect the purposes of
such notice of termination.

     Upon a successor's acceptance of appointment as such, the Trustee shall
notify in writing the Certificateholders and each Rating Agency of such
appointment.

                               EVENTS OF DEFAULT

Section 8.01.   Events of Default.
                -----------------     

     In case one or more of the following Events of Default shall occur and be
continuing, that is to say:

     (a) any failure by the Servicer to make any deposit or payment, or to remit
to the Trustee any payment, required to be made under the terms of this
Agreement which continues unremedied for a period of five days after the date
upon which written notice of such failure, requiring the same to be remedied,
shall have been given to the Servicer by the Trustee or the Contract Seller or
to the Servicer, the Trustee and the Contract Seller by the Holders of
Certificates evidencing Fractional Interests aggregating not less than 25%; or

     (b) failure on the part of the Servicer duly to observe or perform in any
material respect any other of the covenants or agreements on the part of the
Servicer set forth in this Agreement, including the failure to deliver a Monthly
Report, 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 Servicer by the Trustee or the Contract Seller or to the
Servicer, the Trustee and the Contract Seller by the Holders of Certificates
evidencing Fractional Interests aggregating not less than 25%; or

     (c) a decree or order of a court or agency or supervisory authority having
jurisdiction in the premises in an involuntary case under any present or future
federal or state bankruptcy, insolvency or similar law or appointing a
conservator or receiver or liquidator in any insolvency, readjustment of 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; or

     (d) the Servicer shall consent to the appointment of a conservator or
receiver or liquidator in any insolvency, readjustment of debt, marshaling of
assets and liabilities or similar proceedings of or relating to the Servicer or
of or relating to all or substantially all of the Servicer's property; or

     (e) 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
take any corporate action in furtherance of the foregoing;

then, and in each and every such case, so long as such Event of Default shall
not have been cured or waived, the Trustee may, and, the Trustee shall at the
written direction of the Holders of Certificates evidencing Fractional Interests
aggregating not less than 51% by notice in writing to the Servicer, terminate
all the rights and obligations of the Servicer under this Agreement and in and
to the Contracts and the proceeds thereof, except any responsibility for its
acts or omissions during its tenure as Servicer hereunder. The Trustee shall
send a copy of a notice of any Event of

                                      -96-
<PAGE>
 
Default to each Rating Agency. 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 Contracts or otherwise, shall pass to and be vested
in the successor appointed pursuant to Section 7.07. Upon the occurrence of an
Event of Default which shall not have been remedied, the Trustee may also pursue
whatever rights it may have at law or in equity to damages, including injunctive
relief and specific performance. The Trustee will have no obligation to take any
action or institute, conduct or defend any litigation under this Agreement at
the request, order or direction of any of the Certificateholders unless such
Certificateholders have offered to the Trustee reasonable security or indemnity
against the costs, expenses and liabilities which the Trustee may incur.

Section 8.02.   Waiver of Defaults.
                ------------------     

     The Holders of Certificates evidencing Fractional Interests aggregating not
less than 25% may waive any default by the Servicer in the performance of its
obligations hereunder and its consequences, except that a default in the making
of any required remittance to the Trustee for distribution on any of the
Certificates may be waived only by the affected Certificateholders. Upon any
such waiver of a past default, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been remedied for every
purpose of this Agreement. No such waiver shall extend to any subsequent or
other default or impair any right consequent thereon except to the extent
expressly so waived.

Section 8.03.   Trustee to Act; Appointment of Successor.
                ----------------------------------------     

     On and after the time the Servicer receives a notice of termination
pursuant to Section 8.01, the Trustee or its appointed agent shall be the
successor in all respects to the Servicer as provided in Section 7.07 hereof.
Notwithstanding the above, or anything in Section 7.07 to the contrary, the
Trustee, if it becomes Servicer pursuant to this Section, shall have no
responsibility or obligation (i) to repurchase or substitute any Contract, (ii)
for any representation or warranty of the Servicer hereunder, and (iii) for any
act or omission of either a predecessor or successor Servicer other than the
Trustee. The Trustee may conduct any activity required of it as Servicer
hereunder through an Affiliate or through an agent. Neither the Trustee nor any
other successor Servicer shall be deemed to be in default hereunder due to any
act or omission of a predecessor Servicer, including but not limited to failure
to timely deliver to the Trustee any Monthly Report, any funds required to be
deposited to the Trust Fund, or any breach of its duty to cooperate with a
transfer of servicing as required by Section 7.07.

Section 8.04.   Notification to Certificateholders.
                ----------------------------------     

     (a) Upon any such termination pursuant to Section 8.01, the Trustee shall
give prompt written notice thereof to Certificateholders at their respective
addresses appearing in the Certificate Register and to each Rating Agency.

     (b) Within 60 days after the occurrence of any Event of Default, the
Trustee shall transmit by mail to all Holders of Certificates notice of each
such Event of Default hereunder known to the Trustee, unless such Event of
Default shall have been cured or waived.

Section 8.05.   Effect of Transfer.
                ------------------     

     (a) After a transfer of servicing duties to a successor Servicer pursuant
to Section 7.04, 7.06, 7.07 or 8.01, the Trustee or the successor Servicer may
notify Obligors to make payments that are due under the Contracts after the
effective date of the transfer of servicing duties directly to the successor
Servicer.

     (b) After the transfer of servicing duties to a successor Servicer pursuant
to Section 7.04, 7.06, 7.07 or 8.01, the replaced Servicer shall have no further
obligations with respect to the management, administration, servicing or
collection of the Contracts, but in the case of a transfer pursuant to Section
7.07 or 8.01 shall remain liable for any liability arising from the replaced
Servicer's actions hereunder and shall remain entitled to any compensation due
the replaced Servicer that had already accrued prior to such transfer.

     (c) A transfer of servicing duties to a successor Servicer shall not affect
the rights and duties of the parties hereunder (including but not limited to the
indemnities of the Servicer pursuant to Article VII), other than those relating
to the management, administration, servicing or collection of the Contracts.

Section 8.06.   Transfer of the Accounts.
                ------------------------     

     Notwithstanding the provisions of Section 8.01, if the Certificate Account
shall be maintained with the Servicer or an Affiliate of the Servicer and an
Event of Default shall occur and be continuing, the Servicer, after five days'
written notice from the Trustee, or in any event within ten days after the
occurrence of the Event of Default, shall establish a new account, which shall
be an Eligible Account, conforming with the requirements of this Agreement, at
the trust department of the Trustee or with a depository institution other than
the Servicer or an Affiliate of the Servicer, and shall promptly transfer all
funds in the Certificate Account to such new Certificate Account, which shall
thereafter be deemed the Certificate Account for the purposes hereof.

                            CONCERNING THE TRUSTEE

Section 9.01.   Duties of Trustee.
                -----------------     

     The Trustee, prior to the occurrence of an Event of Default and after the
curing or waiving of all Events of Default which may have occurred, undertakes
to perform such duties and only such duties as are set forth specifically in
this Agreement. In case an Event of Default has occurred of which a Responsible
Officer has knowledge (which has not been cured or waived), the Trustee 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 man would
exercise or use under the circumstances in the conduct of his own affairs,
unless it is acting as Servicer pursuant to Section 8.03 in which case it will
use the same degree of care and skill as the Servicer.

     The Trustee, upon receipt of all resolutions, certificates, statements,
opinions, reports, documents, orders or other instruments furnished to the
Trustee which are required specifically to be furnished pursuant to any
provision of this Agreement, shall examine them to determine whether they
conform to the requirements of this Agreement.

     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 misconduct; provided, however, that:
                    --------  -------       

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

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

         (iii) The Trustee shall not be liable personally with respect to any
     action taken, suffered or omitted to be taken by it in good faith in
     accordance with the direction of the Holders of Certificates evidencing
     Fractional Interests aggregating not less than 25% as to the time, method
     and place of conducting any proceeding for any remedy available to the
     Trustee, or exercising any trust or power conferred upon the Trustee, under
     this Agreement.

     None of the provisions contained in this Agreement shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its

                                      -99-
<PAGE>
 
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.

     The Trustee shall have no liability for any loss on any Eligible Investment
except and only to the extent that it is an Obligor thereon.

Section 9.02.   Certain Matters Affecting the Trustee.
                -------------------------------------     

     Except as otherwise provided in Section 9.01:

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

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

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

     (d) The Trustee shall not be liable personally 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;

     (e) Prior to the occurrence of an Event of Default hereunder and after the
curing or waiving of all Events of Default which may have occurred, the Trustee
shall not be bound to make any investigation into the computations, facts or
matters stated in any resolution, certificate, statement, instrument, opinion,
report, any Monthly Report, notice, request, consent, order, approval, bond or
other paper or document, unless requested in writing so to do by the Holders of
Certificates evidencing Fractional Interests aggregating not less than 25%;
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 Servicer, if an Event of Default shall have
occurred and is continuing, and otherwise by the Certificateholders requesting
the investigation;

                                     -100-
<PAGE>
 
     (f)  The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys; provided, however, that any Affiliate of the Contract Seller may only
           --------  -------                                                    
perform ministerial or custodial duties hereunder as agent for the Trustee; and

     (g) The Trustee shall examine any directions, notices or other
communications received from the Servicer, the Contract Seller or any
Certificateholder (or agent thereof) to determine if such directions, notices or
other communications appear on their face to have been made and to otherwise be
in accordance with the requirements of this Agreement.  As long as the Trustee
has acted in good faith and has not been negligent in making determinations
required by this Section 9.02(g), the Trustee may conclusively rely on such
directions, notices or other communications and shall incur no liability
hereunder for complying with, or assuming the truth of the statements contained
in, any such direction, notice or other communication.

Section 9.03.   Trustee not Liable for Certificates or Contracts.
                ------------------------------------------------     

     The recitals contained herein and in the Certificates (other than the
authentication of the Certificates) shall be taken as the statements of the
Contract Seller or the Servicer, as the case may be, and the Trustee assumes no
responsibility for their correctness.  The Trustee makes no representations or
warranties as to the validity or sufficiency of this Agreement, of the
Certificates (except that the Certificates shall be duly and validly
authenticated by it) or of any Contract or related document.  The Trustee shall
not be accountable for the use or application by the Contract Seller or the
Servicer of any of the Certificates or of the proceeds of such Certificates, or
for the use or application of any funds paid to the Contract Seller or the
Servicer in respect of the Contracts or deposited in or withdrawn from the
Certificate Account by the Contract Seller or the Servicer.

Section 9.04.   Trustee May Own Certificates.
                ----------------------------     

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

Section 9.05.   Servicer to Pay Fees and Expenses of Trustee, Paying Agent and
                --------------------------------------------------------------
                Certificate Administrator.
                -------------------------     

     The Servicer covenants and agrees to pay, from its own funds, to the
Trustee, the Paying Agent and the Certificate Administrator from time to time,
and the Trustee, the Paying Agent and the Certificate Administrator shall each
be entitled to, 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 trust hereby created and
in the exercise and performance of any of the powers and duties hereunder of the
Trustee, and the Servicer will pay (out of its own funds) or reimburse the
Trustee, the Paying Agent and the Certificate Administrator, to the extent
requested by the Trustee, the Paying Agent or the Certificate Administrator, as
the case may be, for all reasonable expenses, disbursements and advances
incurred or made by the Trustee, the Paying Agent or the Certificate
Administrator, as the case may be, in accordance with any of the provisions of
this Agreement, and the reasonable

                                     -101-
<PAGE>
 
compensation and the expenses and disbursements of its counsel and of all
persons not regularly in its employ, and the expenses incurred by the Trustee in
connection with the appointment of an office or agency pursuant to Section 9.11,
except any such expense, disbursement or advance as may arise from its
negligence or bad faith.  The Servicer also covenants and agrees to indemnify
(out of its own funds) the Trustee, the Paying Agent and the Certificate
Administrator for, and to hold each of them harmless against, any loss,
liability or expense incurred without negligence or bad faith on the part of the
Trustee, the Paying Agent or the Certificate Administrator, as the case may be,
arising out of or in connection with the acceptance or administration of this
trust and its duties hereunder, including the costs and expenses of defending
itself against any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder.  The covenants in this
Section 9.05 shall b for the benefit of the Trustee, the Paying Agent and the
Certificate Administrator in their respective capacities as Trustee, Certificate
Administrator, Paying Agent and Certificate Registrar hereunder, and shall
survive the termination of this Agreement.

Section 9.06.   Eligibility Requirements for Trustee.
                ------------------------------------     

     There shall at all times be a Trustee hereunder which shall be qualified to
maintain an Eligible Account and shall be either (a) The First National Bank of
Chicago ("First National") or any other Person into which First National is
merged or consolidated or to which substantially all of the properties and
assets of First National are transferred as an entirety, provided that such
                                                         --------          
other Person has accepted appointment as Trustee under this Agreement in
accordance with this Article IX, and further provided that such entity is not an
                                     ------- --------                           
Affiliate of the Contract Seller, is authorized to exercise corporate trust
powers under the laws of the United States of America, any State thereof or the
District of Columbia and has all necessary trust powers to perform its
obligations hereunder, or (b) a corporation or banking association organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least $50,000,000, and
subject to supervision or examination by Federal or State authority, and which
is not an Affiliate of the Contract Seller; further provided that either (i)
                                            ------- --------                
such entity has long-term debt rated at least A3 by Moody's or the equivalent by
any nationally recognized statistical rating organization, or (ii) each Rating
Agency provides a letter to the effect that such appointment will not affect the
then current ratings of the Certificates.  If the corporation or banking
association referred to in clause (b) of the previous sentence publishes reports
of condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section 9.06,
the combined capital and surplus of such corporation or banking association
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  In addition, the Trustee shall
maintain an office in New York.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 9.06, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article IX.

Section 9.07.   Resignation and Removal of the Trustee.
                --------------------------------------     

     The Trustee at any time may resign and be discharged from the trusts hereby
created by giving written notice thereof to the Contract Seller, the Servicer
and each Rating Agency.  Upon

                                     -102-
<PAGE>
 
receiving such notice of resignation, the Contract Seller 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.

     If at any time the Trustee shall cease to be eligible in accordance with
the provisions of Section 9.06 and shall fail to resign after written request
therefor by the Contract Seller, or if at any time the Trustee shall become
incapable of acting, or shall be adjudged bankrupt or insolvent, or a receiver
of the Trustee or of its property shall be appointed, or any public officer
shall take charge or control of the Trustee or of its property or affairs for
the purpose of rehabilitation, conservation or liquidation, then the Contract
Seller 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 and the
Certificateholders.

     The Holders of Certificates evidencing Fractional Interests aggregating not
less than 50% may remove the Trustee at any time and appoint a successor trustee
by written instrument or instruments, in triplicate, signed by such
Certificateholders or their attorneys-in-fact duly authorized, one complete set
of which instruments shall be delivered to the Contract Seller, one complete set
to the Trustee so removed and one complete set to the successor so appointed.

     Any resignation or removal of the Trustee and appointment of a successor
trustee pursuant to any of the provisions of this Section 9.07 shall become
effective upon acceptance of appointment by the successor trustee as provided in
Section 9.08.

Section 9.08.   Successor Trustee.
                -----------------     

     Any successor trustee appointed as provided in Section 9.07 shall execute,
acknowledge and deliver to the Contract Seller and to its predecessor trustee,
with a copy to the Servicer, an instrument accepting such appointment hereunder,
and thereupon the resignation or removal of the predecessor trustee and the
appointment of such successor trustee shall become effective, and such successor
trustee, without any further act, deed or conveyance, shall become fully vested
with all the rights, powers, duties and obligations of its predecessor
hereunder, with the like effect as if originally named as trustee herein.  The
predecessor trustee shall execute and deliver such instruments and do such other
things as reasonably may be required to more fully and certainly vest and
confirm in the successor trustee all such rights, powers, duties and
obligations.

     No successor trustee shall accept appointment as provided in this Section
9.08 unless at the time of such acceptance such successor trustee shall be
eligible under the provisions of Section 9.06.

          Upon acceptance of appointment by a successor trustee as provided in
this Section 9.08, the Servicer shall mail notice of the succession of such
trustee hereunder to all Certificateholders at their addresses as shown in the
Certificate Register, to the Contract Seller and each Rating Agency.  If the
Servicer fails to mail such notice within 10 days after acceptance

                                     -103-
<PAGE>
 
of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Contract Seller.

Section 9.09.   Merger or Consolidation of Trustee.
                ----------------------------------     

     Any corporation into which the Trustee 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 Trustee shall be a party, or any
corporation succeeding to the business of the Trustee, shall be the successor of
the Trustee hereunder, provided such corporation shall be eligible under the
                       --------                                             
provisions of Section 9.06, 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.  Upon succession of a successor trustee as provided in
this Section 9.09, the successor Trustee shall mail notice of the succession of
such trustee hereunder to all Certificateholders at their addresses as shown in
the Certificate Register, to the Servicer and each Rating Agency.

Section 9.10.   Appointment of Co-Trustee or Separate Trustee.
                ---------------------------------------------     

     Notwithstanding any other provisions hereof, at any time, for the purpose
of (i) meeting any legal requirements of any jurisdiction in which any part of
the Trust Fund or property securing the same may be located at the time, or (ii)
meeting any legal requirements with respect to the holding of the Contracts, the
Contract Seller and the Trustee acting jointly shall have the power and shall
execute and deliver all instruments to appoint one or more Persons approved by
the Trustee 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
9.10, such powers, duties, obligations, rights and trusts as the Contract Seller
and the Trustee may consider necessary or desirable.  If the Contract Seller
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.  No
co-trustee or separate trustee hereunder shall be required to meet the terms of
eligibility as a successor trustee under Section 9.06 hereunder, and no notice
to Certificateholders of the appointment of co-trustee(s) or separate trustee(s)
shall be required under Section 9.08 hereof.

     In the case of any appointment of a co-trustee or separate trustee pursuant
to this Section 9.10, 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 or under any regulation applicable to any of the
Contracts (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 any portion thereof in any such
jurisdiction) shall be exercised and performed by such separate trustee or co-
trustee at the direction of the Trustee.

                                     -104-
<PAGE>
 
     Any notice, request or other writing given to the Trustee shall be deemed
to have been given to each of the then separate trustees and co-trustees, as
effectively as if given to each of them.  Every instrument appointing any
separate trustee or co-trustee shall refer to this Agreement and the conditions
of this Article IX.  Each separate trustee and co-trustee, upon its acceptance
of the trusts conferred, shall be vested with the estates or property specified
in its instrument of appointment, either jointly with the Trustee or separately,
as may be provided therein, subject to all the provisions of this Agreement,
specifically including every provision of this Agreement relating to the conduct
of, affecting the liability of, or affording protection to, the Trustee.  Every
such instrument shall be filed with the Trustee.

     Any separate trustee or co-trustee may, at any time, appoint the Trustee
its agent or attorney-in-fact, with full power and authority, to the extent not
prohibited by law, to do any lawful act under or in respect of this Agreement on
its behalf and in its name.  If any separate trustee or co-trustee shall die,
become incapable of acting, resign or be removed, all of its estates,
properties, rights, remedies and trusts shall vest in and be exercised by the
Trustee, to the extent permitted by law, without the appointment of a new or
successor trustee.  Nothing in this Section 9.10 shall relieve the Trustee of
its duties, obligations or liabilities under this Agreement.

Section 9.11.   Appointment of Office or Agency.
                -------------------------------     

     The Trustee will appoint an office or agency in the City of New York where
Certificates may be surrendered for registration of transfer or exchange.  The
Trustee initially designates Chicago Trust Company of New York, located at 14
Wall Street, New York, New York, for such purpose.  The Certificate Register
will be kept in Chicago, Illinois at the offices of the Certificate Registrar
located at the Corporate Trust Office and may be kept in an electronic form
capable of printing out a hard copy of the Certificate Register.  The Trustee
will maintain an office at the address stated in Section 11.05 hereof where
notices and demands to or upon the Trustee in respect of the Certificates may be
served.  The Trustee will give prompt written notice to Certificateholders of
any change in the location of the Certificate Register or any such office or
agency.

Section 9.12.   Certificate Administrator.
                -------------------------     

     The Trustee may, from time to time, appoint a Certificate Administrator for
the purpose of performing, as the Trustee's agent, those duties hereunder that
are specifically designated herein as performable by the Certificate
Administrator; provided, however, that the Certificate Administrator shall at
               --------  -------                                             
all times satisfy the eligibility requirements of a Trustee set forth in Section
9.06.  As of the Closing Date, the Trustee shall be the Certificate
Administrator unless and until the Trustee appoints a successor Certificate
Administrator.  In performing its duties hereunder, the Certificate
Administrator (if not the Trustee) shall have the benefit of the provisions of
this Agreement to the same extent that the Trustee would have the benefit of
such provisions if the Trustee were itself performing such duties.  The
Certificate Administrator (including the Trustee solely in its capacity as
Certificate Administrator) shall not have any fiduciary responsibility to the
Contract Seller, the Servicer or the Certificateholders except when acting as
Paying Agent.  Additionally, the Certificate Administrator shall be entitled to
rely upon all directions, calculations 

                                     -105-
<PAGE>
 
and other information received by the Contract Seller, the Trustee or the
Servicer without any duty to independently verify such directions, calculations
or other information.

Section 9.13.   Appointment of Paying Agent.
                ---------------------------     

     The Trustee may appoint a Paying Agent for the purpose of making
distributions to Certificateholders pursuant to Section 5.02 and payments
pursuant to 3.17 and 9.01(c).  Any Paying Agent or its parent company so
appointed either shall be a bank or trust company and shall have a rating
acceptable to each Rating Agency. In the event of any such appointment, on or
prior to each Distribution Date, the Trustee shall deposit or cause to be
deposited with the Paying Agent, from amounts in the Certificate Account, a sum
sufficient to make the payments to Certificateholders in the amounts and in the
manner provided for in Section 5.02, such sum to be held in trust for the
benefit of the Certificateholders.  The Trustee is hereby initially appointed as
Paying Agent.

     In performing its duties hereunder, the Paying Agent shall have the benefit
of the provisions of this Agreement to the same extent that the Trustee would
have the benefit of such provisions if the Trustee were itself performing such
duties.  Additionally, the Paying Agent shall be entitled to rely upon all
information received from the Servicer without any duty to independently verify
or recalculate any such information.

     The Trustee shall cause the Paying Agent to execute and deliver to the
Trustee an instrument in which such Paying Agent shall agree with the Trustee
that such Paying Agent is at all times acting as agent for the Trustee and such
Paying Agent will hold all sums held by it for the payment to Certificateholders
entitled thereto until such sums shall be paid to such Certificateholders.

Section 10.01.   Termination.
                 -----------     

     (a) The respective obligations and responsibilities of the Contract Seller,
the Servicer (except as to Section 9.05) and the Trustee shall terminate upon
the earlier of:  (i) the final payment or other liquidation (or any advance with
respect thereto) of the last Contract or the disposition of all property
acquired upon repossession of any Contract and the remittance of all funds due
hereunder; (ii) at the option of the Servicer, on any Distribution Date after
the first Distribution Date on which the Pool Scheduled Principal Balance is
less than 10% of the Cut-off Date Pool Principal Balance and subject to the
prior consummation of the Termination Auction as contemplated pursuant to
Section 10.01(b) below, upon the purchase by the Servicer of the Outstanding
Contracts at a price equal to the greater of (a) the sum of (x) 100% of the
Scheduled Principal Balance of each Contract (other than any Contract as to
which the related Manufactured Home has been acquired and not yet disposed of
and whose fair market value is included pursuant to Clause (y) below) as of the
final Distribution Date, and (y) the fair market value of such acquired property
(as determined by the Servicer as of the close of business on the third Business
Day next preceding the date upon which notice of any such termination is
furnished to Certificateholders pursuant to Section 10.01(c)(i)), and (b) the
aggregate fair market value (as determined by the Servicer as of the close of
business on such third Business Day) of all the assets in the Trust Fund, plus,
in the case of both clause (a) and clause (b), an amount sufficient to pay any
Class A-1 Unpaid Interest Shortfall, Class A-2 Unpaid Interest Shortfall, Class
A-3 Unpaid Interest Shortfall, Class A-4 Unpaid Interest Shortfall, Class A-5
Unpaid Interest Shortfall, Class A-6 Unpaid Interest Shortfall, Class A-7 Unpaid

                                                                   -------- 
that the purchase price of such Contracts shall in no event be less than the
Minimum Termination Amount as of the Distribution Date on which the Servicer
purchases such Contracts; or (iii) the sale of all Contracts that remain
outstanding, pursuant to a Termination Auction as contemplated by Section
10.01(b) below and the remittance of all funds due hereunder.  Notwithstanding
anything herein to the contrary, 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.

     (b) Termination Auction.  The Servicer shall provide written notice to the
         -------------------                                                   
Trustee of the occurrence of the Distribution Date as of which the Pool
Scheduled Principal Balance is less than 10% of the Cut-Off Date Pool Principal
Balance within three Business Days following such Distribution Date.  Thereupon,
the Trustee shall in accordance with the procedures and schedule set forth in
Exhibit L hereto (the "Auction Procedures"), make a commercially reasonable
- ---------                                                                  
effort to sell at fair market value in a commercially reasonable manner and upon
commercially reasonable terms but subject to the earlier purchase by the
Servicer of the Outstanding Contracts as provided in Section 10.01(a) above, by
conducting an auction (the "Termination Auction") of the Contracts remaining in
the Trust Fund in order to effect a termination of the Trust Fund on a 

                                     -107-
<PAGE>
 
date selected by the Trustee (the "Auction Date"), but in any case within ninety
days following the Distribution Date as of which the Pool Scheduled Principal
Balance is less than 10% of the Cut-off Date Pool Principal Balance. The
Contract Seller (and the Servicer if BAFSB is not the Servicer) may, but shall
not be required to, bid at the Termination Auction. The Trustee shall be
entitled to retain counsel of its choice to represent it in the Termination
Auction, and the fees and expenses of such counsel shall be paid by the Contract
Seller. The Trustee shall sell and transfer the Contracts to the highest bidder
therefor at the Termination Auction provided that:

          (1)  the Termination Auction has been conducted in accordance with the
     Auction Procedures;

          (2)  the Trustee has received good faith bids for the Contracts from
     at least two prospective purchasers that are considered by the Trustee, in
     its sole discretion, to be competitive participants in the market for
     Manufactured housing installment sale contracts; provided, that at least
                                                      --------               
     one of such prospective purchasers shall not be an Affiliate of either of
     the Contract Seller;

          (3)  a financial advisor selected by the Trustee, the fees of whom
     shall be an expense of the Contract Seller, as advisor to the Trustee (in
     such capacity, the "Advisor"), shall have advised the Trustee in writing
     that at least two of such bidders are participants in the market for
     manufactured housing retail installment sale contracts and are willing and
     able to purchase the Contracts (the Trustee may in its discretion select
     itself or an affiliate thereof as Advisor);

          (4)  the highest bid in respect of the Contracts is not less than the
     aggregate fair market value of the Contracts (as determined by the Trustee
     in its sole discretion);

          (5)  any bid submitted by the Contract Seller or any Affiliate of
     either of them shall be independently verified and represented in writing
     by a qualified independent third party evaluator (which may include the
     Advisor or an investment banking firm) selected by the Trustee and may only
     be considered if such evaluator determines that the bid reasonably
     represents the fair market value of the Contracts;

          (6)  the highest bid would result in proceeds from the sale of the
     Contracts which will be at least equal to the Minimum Termination Amount;

          (7)  such sale and consequent termination of the Trust Fund must
     constitute a "qualified liquidation" of the Trust Fund under Section 860F
     of the Code, including the requirement that the proceeds of such qualified
     liquidation are credited or distributed to the holders of regular residual
     interests within 90 days from the date upon which the Trust Fund adopts a
     plan of complete liquidation (the Trustee may, in its discretion, require
     that the purchaser of such Contracts provide an Opinion of Counsel to that
     effect); and

          (8)  the terms of the Termination Auction must be made available to
     all bidders and must stipulate that the Servicer be retained to service the
     Contracts on terms substantially similar to those in this Agreement.

                                     -108-
<PAGE>
 
     Provided that all of the conditions set forth in clauses (1) through (8)
have been met, the Trustee shall sell and transfer the Contracts, without
representation, warranty or recourse of any kind whatsoever, to such highest
bidder in accordance with and upon completion of the Auction Procedures.  The
Trustee shall deposit the purchase price for the Contracts in the Certificate
Account at least one Business Day prior to the fourth Distribution Date
following the Distribution Date as of which the Pool Scheduled Principal Balance
is less than 10% of the Cut-off Date Pool Principal Balance.  The provisions of
subsections (c) and (d) of this Section 10.01 also shall apply with respect to
any Termination Auction.  In the event that any of such conditions are not met
or such highest bidder fails or refuses to comply with any of the Auction
Procedures, the Trustee shall decline to consummate such sale and transfer.  In
such case the Termination Auction shall be concluded and the Trustee shall be
under no further duty to solicit bids for or otherwise to attempt to sell the
Contracts.

     (c) (i) Notice of any termination, specifying the Distribution Date upon
which all Certificateholders may surrender their Certificates to the Trustee for
payment and cancellation, shall be given promptly by the Servicer by letter to
the Certificateholders, the Trustee, the Contract Seller and each Rating Agency
mailed no later than the 10th day of the month next 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 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 therein specified.  After giving such notice, the Trustee shall not
register the transfer or exchange of any Certificates.  If such notice is given
in connection with the Servicer's election to purchase, the Servicer shall
deposit in the Certificate Account on the Business Day prior to the applicable
Distribution Date the amount described in Section 10.01(a)(ii).  The amount so
deposited shall not be invested.

          (ii) Upon presentation and surrender of the Certificates, the Trustee
     shall cause to be distributed, from funds in the Certificate Account, to
     Certificateholders, in proportion to their respective Percentage Interests,
     an amount equal to (a) as to the Class A-1 Certificates, the Class A-1
     Certificate Balance together with the Class A-1 Unpaid Interest Shortfall

     Certificate Balance together with the Class A-6 Unpaid Interest Shortfall
     and one month's interest at the Class A-6 Pass-Through Rate on the Class A-

     to the Class A-7 Certificates, the Class A-7 Certificate Balance together
     with the Class A-7 Unpaid Interest Shortfall and one month's interest at
     the Class A-7 Pass-Through Rate on the Class A-7 Certificate Balance, (h)

     together with the Class B-2 Unpaid Interest Shortfall and one month's 
     interest at the Class B-2 Pass-Through Rate on the Class B-2 Certificate
     Balance.

          (iii)  Upon such termination, any amounts remaining in the Certificate
     Account and the Reserve Account (other than amounts retained to meet
     claims) shall be paid to the Class R Certificateholders.  Following such
     final deposit, the Servicer shall prepare and the Trustee shall execute all
     assignments, endorsements and other instruments necessary to effectuate
     such transfer.  The distribution on the final Distribution Date shall be in
     lieu of the distribution otherwise required to be made on such Distribution
     Date in respect of the Certificates and the Class R Certificate.

     (d)  If any Certificateholder does not surrender its Certificate for
cancellation by the final Distribution Date specified in the written notice
required in Section 10.01(c)(i), any amounts retained in the Certificate Account
that are owed to such Certificateholder shall be withdrawn from the Certificate
Account and held in an escrow account with the Trustee pending distribution
pursuant to this Section 10.01(d).  Any amounts so held shall not be invested.
The Trustee shall give a second written notice to the remaining
Certificateholders to surrender their Certificates for cancellation and receive
the final distribution with respect thereto.  If within two years after the
second notice all the Certificates shall not have been surrendered for
cancellation, the Trustee shall so notify the Contract Seller and the Contract
Seller may take appropriate steps, or may appoint an agent to take appropriate
and reasonable steps, to contact the remaining Certificateholders concerning
surrender of their Certificates, and the cost thereof shall be paid out of, and
only to the extent of, the funds and other assets which remain in trust
hereunder.

     Upon any termination pursuant to the exercise of the purchase option
contained in Section 10.01(a)(ii), the consummation of a sale pursuant to a
Termination Auction or otherwise, the Trust Fund shall be terminated in
accordance with the following additional requirements, unless the Trustee has
received an Opinion of Counsel to the effect that the failure of the Trust Fund
to comply with the requirements of this Section 10.01 will not (i) result in the
imposition of taxes on "prohibited transactions" of the Trust Fund as described
in Section 860F of the Code, (ii) cause

                                     -110-
<PAGE>
 
the Trust Fund to fail to qualify as a REMIC at any time that any Certificates
are outstanding, or (iii) result in the imposition of taxes on contributions of
additional assets to the Trust Fund under Section 860G(d) of the Code:

          (i)  Within 90 days prior to the final Distribution Date set forth in
     the notice given by the Servicer or the Trustee under this Section 10.01,
     the Holders of the Class R Certificates shall adopt a plan of complete
     liquidation of the Trust Fund;

          (ii)  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
     purchaser thereof (which may be the Servicer) for cash (other than assets
     that will be converted to cash prior to the final Distribution Date); and

          (iii)  At or after the time of adoption of such a plan of complete
     liquidation and at or prior to the final Distribution Date, the Trustee
     shall credit or distribute all proceeds of the liquidation (plus the cash),
     less assets retained to meet claims, to the Certificateholders.

By its acceptance of a Class R Certificate, each Holder thereof hereby agrees to
adopt such a plan of complete liquidation upon the written request of the
Servicer and to take such other action in connection therewith as may be
reasonably requested by the Contract Seller.

Section 11.01.   Amendment.
                 ---------     

     This Agreement may be amended from time to time by the Contract Seller, the
Servicer and the Trustee without the consent of any of the Certificateholders,
(i) to cure any ambiguity, (ii) to correct or supplement any provisions herein,
(iii) to add to the duties or obligations of the Servicer, (iv) to obtain a
rating from a nationally recognized rating agency or to maintain or improve the
ratings of any Class of Certificates by each Rating Agency (it being understood
that after obtaining ratings for the Certificates from Moody's and Fitch, none
of the Trustee, the Contract Seller or the Servicer is obligated to obtain,
maintain or improve any rating assigned to the Certificates) or (v) to make such
other provisions with respect to matters or questions arising under this
Agreement, as shall not be inconsistent with any other provisions herein;
provided that such action shall not, as evidenced by an Opinion of Counsel,
- --------                                                                   
adversely affect in any material respect the interests of any Certificateholder.
Notwithstanding the foregoing, without the consent of the Certificateholders,
the Trustee, the Contract Seller and the Servicer may at any time and from time
to time amend this Agreement to modify, eliminate or add to any of its
provisions to such extent as shall be necessary or appropriate to maintain the
qualification of the Trust Fund as a REMIC under the Code or to avoid or
minimize the risk of the imposition of any tax on the Trust Fund pursuant to the
Code that would be a claim against the Trust Fund at any time prior to the final
redemption of the Certificates, provided that the Trustee has been provided an
Opinion of Counsel, which opinion shall be an expense of the party requesting
such opinion but in any case shall not be an expense of the Trustee, to the
effect that such action is necessary or appropriate to maintain such
qualification or to avoid or minimize the risk of the imposition of such a tax.

     This Agreement may also be amended from time to time by the Contract
Seller, the Servicer and the Trustee with the consent of the Holders of a
Majority In Interest of each Class of Regular Certificates affected thereby for
the purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Agreement or of modifying in any manner the rights
of the Holders of Certificates; provided, however, that no such amendment shall
                                --------  -------                              
(i) reduce in any manner the amount of, or delay the timing of, payments
required to be distributed on any Certificate without the consent of the Holder
of such Certificate, (ii) adversely affect in any material respect the interests
of the Holders of any Class of Certificates in a manner other than as described
in (i), without the consent of the Holders of Certificates of such Class
evidencing, as to such Class, Percentage Interests aggregating 66% or (iii)
reduce the aforesaid percentages of Certificates the Holders of which are
required to consent to any such amendment, without the consent of the Holders of
all such Certificates then outstanding.

     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, which opinion shall be an expense of the party
requesting such amendment but in any case shall not be an expense of the
Trustee, to the effect that such amendment will not cause the imposition of any
tax on the Trust Fund or the Certificateholders or cause the Trust Fund to fail
to qualify as a REMIC at any time that any Certificates are outstanding.

                                     -112-

     Promptly after the execution of any amendment to this Agreement requiring
the consent of Certificateholders, 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 Certificateholders under this
Section 11.01 to approve the particular form of any proposed amendment, but it
shall be sufficient if such consent shall approve the substance thereof.  The
manner of obtaining such consents and of evidencing the authorization of the
execution thereof by Certificateholders shall be subject to such reasonable
regulations as the Trustee may prescribe.

     Nothing in this Agreement shall require the Trustee to enter into an
amendment without receiving an Opinion of Counsel, satisfactory to the Trustee
that (i) such amendment is permitted and is not prohibited by this Agreement and
that all requirements for amending this Agreement have been complied with; and
(ii) either (A) the amendment does not adversely affect in any material respect
the interests of any Certificateholder or (B) the conclusion set forth in the
immediately preceding clause (A) is not required to be reached pursuant to this
Section 11.01.

for real property records in all the counties or other comparable jurisdictions
in which any or all of the properties subject to the Contracts are situated, and
in any other appropriate public recording office or elsewhere, such recordation
to be effected by the Servicer at its expense.

     For the purpose of facilitating the recordation of this Agreement as herein
provided and for other purposes, this Agreement may be executed simultaneously

instrument.

                 ------------------------------------------     

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

     No Certificateholder shall have any right to vote (except as provided
herein) or in any manner otherwise control the operation and management of the

of Default and of the continuance thereof, as hereinbefore provided, and unless
the Holders of Certificates evidencing not less than 25% of the Voting Rights
evidenced by the Certificates shall also have made written request to 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

themselves of any provisions of this Agreement to affect, disturb or prejudice
the rights of the Holders of any other of the Certificates, or to obtain or seek
to obtain priority over or preference

hereby authorizes such accountants to discuss with such representative such

     Principal in respect of this Certificate is distributable monthly as set

the Certificate Balance as set forth herein.  Neither this Certificate nor the
Contracts are insured or guaranteed by the Contract Seller, the Servicer or the

     This certifies that Cede & Co. is the registered owner of the Percentage

the Agreement.  This Certificate is issued under and is subject to the terms,
provisions and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Holder is bound.

     Pursuant to the terms of the Agreement, a distribution will be made on the

immediately available funds to the account of the Holder hereof at a bank or
other entity having appropriate facilities therefor, if such Certificateholder
shall have so notified the Trustee in writing at least five Business Days prior

which manufactured housing contracts were originated or acquired by Bank of

Trustee to any obligation or liability in addition to those undertaken in the
Agreement or (ii) a representation letter, in the form as described by the
Agreement, stating either (a) that the transferee is not an employee benefit or
other plan subject to the prohibited transaction provisions of ERISA or Section
4975 of the Code (a "Plan"), or any other person (including an investment
manager, a named fiduciary or a trustee of any Plan) acting, directly or
indirectly, on behalf of or purchasing any Certificate with "plan assets" of any
Plan, or (b) that the transferee is an insurance company, the source of funds to
be used by it to purchase the Certificate is an "insurance company general
account" (within the meaning of Department of Labor Prohibited Transaction Class
Exemption ("PTCE") 95-60), and the purchase is being made in reliance upon the
availability of the exemptive relief afforded under Sections I and III of PTCE
95-60.

forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

less than or equal to 10% of the Cut-off Date Pool Principal  Balance, the
Servicer may request that the Trustee conduct an auction (a "Termination
Auction") by soliciting bids for the purchase of all Contracts remaining in the
Trust Fund, and in any event, if the Servicer has not exercised the

                                  Exhibit C-2
<PAGE>
 
option described in the preceding paragraph within ninety days following the
Distribution Date as of which the Pool Scheduled Principal Balance is less than
10% of the Cut-off Date Pool Scheduled Principal Balance, the Trustee shall
conduct such termination auction.  In the event that satisfactory bids are
received as described in the Agreement, the net sale proceeds will be
distributed to Certificateholders, in the same order of priority as collections
received in respect of the Contracts.  A satisfactory bid is one in which the
purchase price of the Contracts then outstanding is at least equal to the
Minimum Termination Amount (as hereinafter defined).  Such a bid must be made in
accordance with certain auction procedures set forth in the Agreement, which
include a requirement that the Trustee receive good faith bids for such
Contracts from at least two prospective purchasers (at least one of whom is not
the Contract Seller or an affiliate thereof) that are considered by the Trustee,
in its sole discretion, to be (i) competitive participants in the market for
manufactured housing installment sale contracts or installment loan agreements
and (ii) willing and able purchasers of such Contracts.  As of any time after
the Pool Scheduled.  Principal Balance is less than 10% of the Cut-off Date Pool
Scheduled Principal Balance, the "Minimum Termination Amount" is an amount equal
to the respective Certificate Balances of all Classes of Certificates that
remain outstanding as of such time, together with any shortfall in interest due
on such Certificates in respect of prior Distribution Dates and one month's
interest at the applicable Pass-Through Rates on such Certificate Balances.  A
sale and consequent termination of the Trust Fund pursuant to a Termination
Auction must constitute a "qualified liquidation" of the Trust Fund under
Section 860F of the Code, including the requirement that the qualified
liquidation takes place over a period not to exceed 90 days.  If satisfactory
bids are not received, the Trustee shall decline to sell the Contracts and shall
not be under any obligation to solicit any further bids or otherwise negotiate
any further sale of the Contracts.

     Any repurchase pursuant to a Termination Auction or by the Servicer will be
made at the price specified in the Agreement.  In the event that no such early
termination occurs, the obligations and responsibilities created by the
Agreement will terminate upon the later of the final payment or other
liquidation of the last Contract remaining in the Trust Fund and the disposition
of all REO Property in respect thereof and the distribution to
Certificateholders of all amounts required to be distributed pursuant to the
Agreement.  In no event, however, will the trust created by the Agreement
continue beyond the expiration of 21 years from the death of the last survivor
of the descendants living at the date of the Agreement of the certain person
named in the Agreement.

     Any term used herein that is defined in the Agreement shall have the
meaning assigned in the Agreement, and nothing herein shall be deemed
inconsistent with that meaning.

     evidencing a percentage interest in any distributions allocable to the
     Class R Certificates with respect to a Trust Fund consisting primarily of a
     pool of fixed-rate conventional manufactured housing contracts (the
     "Contracts") formed and sold by

          Bank of America, FSB, as Contract Seller (the "Contract Seller")

which manufactured housing contracts were originated or acquired by Bank of
America, FSB ("BAFSB"), and are initially serviced by BAFSB, acting through its
division, BankAmerica Housing Services (the "Servicer").

     Neither this Certificate nor the Contracts are insured or guaranteed by the
Contract Seller, the Servicer or the Trustee referred to below or any of their
respective Affiliates or by any governmental agency or instrumentality.

     This certifies that ___________ is the registered owner of the Percentage
Interest evidenced by this Certificate in certain monthly distributions with
respect to a Trust Fund consisting of the Contracts deposited by the Contract
Seller.  The Trust Fund was created pursuant to a Pooling and Servicing
Agreement, dated as of November 1, 1997 (the "Agreement"), between the Contract
Seller, the Servicer, and The First National Bank of Chicago, as trustee (the
"Trustee").  To the extent not defined herein, the capitalized terms used herein
have the meanings assigned in the Agreement.  This Certificate is issued under
and is subject to the terms, provisions and conditions of the Agreement, to
which Agreement the Holder of this Certificate by virtue of the acceptance
hereof assents and by which such Holder is bound.

     The Trustee will cause to be distributed to the Class R Certificateholder
the amounts to which such Holder is entitled pursuant to the terms of the
Agreement.  Such distributions will be made by check mailed to the address of
the Person entitled thereto, as such address shall appear on the Certificate
Register or by wire or other transfer of immediately available funds if such
Person has given the Trustee written instructions at least ten days prior to the
related Distribution Date.  Notwithstanding the above, the final distribution on
this Class R Certificate will be made only upon presentation and surrender of
this Class R Certificate at the Corporate Trust Office or the office or agency
maintained by the Trustee for such purpose.

     No transfer of this Class R Certificate will be made unless the Trustee has
received either (i) an Opinion of Counsel acceptable to and in form and
substance satisfactory to the Trustee, the Contract Seller and the Servicer with
respect to the permissibility of such transfer under the Employee Retirement
Income Security Act of 1974, as amended ("ERISA"), and Section 4975 of the
Internal Revenue Code (the "Code") and stating, among other things, that the
transferee's acquisition of Class R Certificate will not constitute or result in
a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975
of the Code and will not subject the Servicer, the Contract Seller or the
Trustee to any obligation or liability in addition to those

                                  Exhibit D-3
<PAGE>
 
undertaken in the Agreement or (ii) a representation letter, in the form as
described by the Agreement, stating that the transferee is not an employee
benefit or other plan subject to the prohibited transaction provisions of ERISA
or Section 4975 of the Code (a "Plan"), or any other person (including an
investment manager, a named fiduciary or a trustee of any Plan) acting, directly
or indirectly, on behalf of or purchasing any Certificate with "plan assets" of
any Plan.

     No transfer of a Class R Certificate shall be made unless such transfer is
exempt from the registration requirements of the Securities Act of 1933, as
amended, (the "Act"), or is made in accordance with said Act.  In the event that
such a transfer is to be made, the prospective transferee of such Certificate
shall be required to provide the Trustee, the Contract Seller and the Servicer
with an investment letter substantially in the form described by the Agreement,
as required under Section 6.02 of the Agreement.  The Holder hereof desiring to
effect such transfer shall, and does hereby agree to, indemnify the Trustee, the
Contract Seller, the Servicer and the Certificate Registrar acting on behalf of
the Trustee against any liability that may result if the transfer is not so
exempt or is not made in accordance with the Act or any similar state laws.

     Each Holder of this Class R Certificate will be deemed to have agreed to be
bound by the restrictions of Section 6.02 of the Agreement, including but not
limited to the restrictions that (i) each person holding or acquiring any
Ownership Interest in this Class R Certificate must be a Permitted Transferee,
(ii) no Ownership Interest in this Class R Certificate may be transferred
without delivery to the Trustee of (a) a transfer affidavit of the proposed
transferee and (b) a transfer certificate of the transferor, each of such
documents to be in the form described in the Agreement, (iii) each person
holding or acquiring any Ownership Interest in this Class R Certificate must
agree to require a transfer affidavit and to deliver a transfer certificate to
the Trustee as required pursuant to the Agreement, (iv) each person holding or
acquiring an Ownership Interest in this Class R Certificate must agree not to
transfer an Ownership Interest in this Class R Certificate if it has actual
knowledge that the proposed transferee is not a Permitted Transferee and (v) any
attempted or purported transfer of any Ownership Interest in this Class R
Certificate in violation of such restrictions will be absolutely null and void
and will vest no rights in the purported transferee.

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

     This Certificate shall not be entitled to any benefit under the Agreement
or be valid for any purpose unless the certificate of authentication hereon has
been manually executed by an authorized officer of the Trustee.

     IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly
executed.

STATE OF       )
               )ss
COUNTY OF      )

     The undersigned, being first duly sworn, deposes and says as follows:

          1. That he/she is [Title of Officer] of [Name of Owner] (record or
beneficial owner of the BankAmerica Manufactured Housing Contract Trust III
Senior/Subordinate Pass-Through Certificates, Series 1997-2, Class R (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/she makes this affidavit and agreement.

          2. That the Owner (i) is not and will not be a "disqualified
organization" as of [date of transfer] within the meaning of Section 860E(e)(5)
of the Internal Revenue Code of 1986, as amended (the "Code"), (ii) will
endeavor to remain other than a disqualified organization for so long as it
retains its ownership interest in the Class R Certificates, and (iii) is
acquiring the Class R Certificates 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, 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 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 Class R Certificates to disqualified organizations under the Code,
that applies to all transfers of Class R Certificates after March 31, 1988; (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 furnishes 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 Certificates may be "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, unless no significant purpose of the transfer was to impede the
assessment or collection of tax.

                                 Exhibit G-1-1
<PAGE>
 
          4. That the Owner is aware of the tax imposed on a "pass-through
entity" holding Class R Certificates if at any time during the taxable year of
the pass-through entity a disqualified organization is the record holder of an
interest in such entity. (For this purpose, a "pass through entity" includes a
regulated investment company, a real estate investment trust or common trust
fund, a partnership, trust or estate, and certain cooperatives.)

          5. The Owner is not an employee benefit plan or other plan subject to
the prohibited transaction provisions of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), or Section 4975 of the Code, or an investment
manager, named fiduciary or a trustee of any such plan, or any other Person
acting, directly or indirectly, on behalf of or purchasing any Certificate with
"plan assets" of any such plan.

          6. That the Owner is aware that the Trustee will not register the
transfer of any Class R Certificates unless the transferee, or the transferee's
agent, delivers to it 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.

          7. That the Owner has reviewed the restrictions set forth on the face
of the Class R Certificates and the provisions of Section 6.02(c) of the Pooling
and Servicing Agreement (the "Agreement") under which the Class R Certificates
were issued (in particular, clause (iii)(A) and (iii)(B) of Section 6.02(c)
which authorize the Trustee to deliver payments to a person other than the Owner
and negotiate a mandatory sale by the Trustee in the event the Owner holds such
Certificates in violation of Section 6.02(c)). The Owner expressly agrees to be
bound by and to comply with such restrictions and provisions.

          8. 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 Certificates will only be
owned, directly or indirectly, by an Owner that is not a disqualified
organization.

          9. The Owner's Taxpayer Identification Number is ____________.

          10. This affidavit and agreement relates only to the Class R
Certificates held by the Owner and not to any other holder of the Class R
Certificates. The Owner understands that the liabilities described herein relate
only to the Class R Certificates.

          11. That no purpose of the Owner relating to the transfer of any of
the Class R Certificates by the Owner is or will be to impede the assessment or
collections of any tax.

          12. 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. In this regard, the Owner hereby represents to
and for the benefit of the person from whom it acquired the Class R Certificate
that the Owner intends to pay taxes associated with holding such Class R
Certificate as they become due, fully understanding that it may incur tax
liabilities in excess of any cash flows generated by the Class R Certificate.

                                 Exhibit G-1-2
<PAGE>
 
          13. 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 Class R Certificates remain outstanding.

          14. 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 state thereof (including the District of Columbia),
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.


     IN WITNESS WHEREOF, the Transferee has caused this instrument to be
executed on its behalf, pursuant to authority of its Board of Directors, by its
duly authorized officer and its corporate seal to be hereunto affixed, duly

               -----------------------------------------------------------

Ladies and Gentlemen:

     This letter is delivered to you in connection with the transfer by
________(the "Transferor") to _________(the "Buyer") of $___________Initial
Certificate Principal Balance of BankAmerica Manufactured Housing Contract Trust
III Senior/Subordinate  Pass-Through Certificates, Series 1997-2, Class R (the
"Certificates"), issued pursuant to Section 6.02(c) of the Pooling and Servicing
Agreement (the "Agreement"), dated as of November 1, 1997 among Bank of America,
FSB, acting through its division, BankAmerica Housing Services (the "Contract
Seller") and (the "Servicer"), and First National Bank of Chicago (the
"Trustee").  All terms used herein and not otherwise defined shall have the
meanings set forth in the Agreement.  The Transferor hereby certifies,
represents and warrants to, and covenants with, the Contract Seller and the
Trustee that:

     1.  No purpose of the Transferor relating to the transfer of the
Certificate by the Transferor to the Buyer is or will be to impede the
assessment or collection of any tax.

     2.  The Transferor understands that the Buyer has delivered to the Trustee
and the Servicer a transfer affidavit and agreement in the form attached to the
Agreement as Exhibit G-1.  The Transferor does not know or believe that any
representation contained therein is false.

     3.  The Transferor has at the time of the transfer conducted a reasonable
investigation of the financial condition of the Buyer as contemplated by
Treasury Regulations Section 1.860E-1(c)(4)(i) and, as a result of that
investigation, the Transferor has determined that the Buyer has historically
paid its debts as they become due and has found no significant evidence to
indicate that the Buyer will not continue to pay its debts as they become due in
the future.  The Transferor understands that the transfer of a Class R
Certificate may not be respected for United States income tax purposes (and the
Transferor may continue to be liable for United States income taxes associated
therewith) unless the Transferor has conducted such an investigation.

                                 Exhibit G-2-1
<PAGE>
 
     4.  The Transferor has no actual knowledge that the proposed Buyer is not
both a United States Person and a Permitted Transferee.

     5.  The Transferor further certifies that (a) we understand that such
Certificates have not been registered under the Securities Act of 1933, as
amended (the "Act"), and are being disposed of by us in a transaction that is
exempt from the registration requirements of the Act, (b) neither the Transferor
nor anyone acting on its behalf has (i) offered, pledged, sold, disposed of or
otherwise transferred any Certificate, any interest in any Certificate or any
other similar security from any person in any manner, (ii) solicited any offer
to buy or to accept a pledge, disposition or other transfer of any Certificate,
any interest in any Certificate or any other similar security from any person in
any manner, (iii) otherwise approached or negotiated with respect to any
Certificate, any interest in any Certificate or any other similar security from
any person in any manner, (iv) made any general solicitation by means of general
advertising or in any other manner, or (v) taken any other action, that (as to
any of (i) through (v) above) would constitute a distribution of the
Certificates under the Act, that would render the disposition of any Certificate
a violation of Section 5 of the Act or any state securities law, or that would
require registration or qualification pursuant thereto, or (c) to the extent
such transfer is pursuant to Rule 144A under the Act, we have not offered the
Certificates to anyone other than a "qualified institutional buyer" as defined
in Rule 144A and the Act.  The Transferor will not act, in any manner set forth
in the foregoing sentence with respect to any Certificate.  The Transferor has
not and will not sell or otherwise transfer any of the Certificates, except in
compliance with the provisions of the Agreement.

                                                Very truly yours,

          the Certificates; (ii) a copy of all monthly servicing reports or a
          copy of all annual servicing reports and the prior year's monthly
          servicing reports; (iii) a form of a Sale and Servicing Agreement
          prepared by the Trustee and the Servicer (or prepared by the Advisor
          and approved by the Trustee and the Servicer); (iv) a description of

          the Cut-off Date tables for the prospectus supplement dated
          ______________, 1997 relating to the public offering of certain of the
          Certificates.  None of the Trustee, the Servicer or the Contract
          Seller shall be required to produce an updated prospectus or
          prospectus supplement, and the auction procedures shall be carried out
          in a manner that does not constitute a public offering of securities.

     (c)  The Trustee, with the assistance of the Servicer and the Advisor, will
          maintain an auction package beginning at the time of closing of the

<PAGE>
 
     (d)  The Advisor will send solicitation packages to all bidders at least 15
          Business Days before the Auction Date.  Bidders will be required to
          submit any due diligence questions in writing to the Advisor for
          determination of their relevancy, no later than 10 Business Days
          before the Auction Date.  The Servicer and the Advisor will be
          required to satisfy all relevant questions at least five Business Days

          all bidders.

II.  Auction Process
     ---------------

     (a)  The Advisor, any underwriter, or any Certificate Owner will be allowed
          to bid in the Auction, but will not be required to do so.

     (b)  The Servicer will also be allowed to bid in the Termination Auction if
          it deems appropriate, but will not be required to do so.

     (c)  On the Auction Date, all bids will be due by facsimile to the offices
          of the Trustee by 1:00 p.m. New York City time, with the winning
          bidder to be notified by 2:00 p.m. New York City time.  All acceptable
          bids (as described in Section 10.01 (b) of the Agreement) will be due
          on a conforming basis on the bid sheet contained in the solicitation
          package.

     (d)  If the Trustee receives fewer than two market value bids from
          participants in the market for manufactured housing installment sales
          contracts and installment loan contracts willing and able to purchase
          the Contracts, the Trustee shall decline to consummate the sale.

     (e)  Upon notification to the winning bidder, a good faith deposit equal to
          one percent (1%) of the Pool Scheduled Principal Balance will be
          required to be wired to the Trustee upon acceptance of the bid.  This
          deposit, along with any interest income attributable to it, will be
          credited to the purchase price but will not be refundable.  The
          trustee will establish a separate account for the acceptance of the
          good faith deposit, until such time as the account is fully funded and
          all monies are transferred into the Collection Account, such time not
          to be later than one Business Day before the related Distribution Date
          (as described above).

     (f)  The winning bidder will receive on the Auction Date a copy of the
          draft Sale and Servicing Agreement and Servicer's Representations and
          Warranties (which shall be substantially identical to the
          representations and warranties set forth in Section 3.01 of the
          Agreement).

     (g)  The Advisor will provide to the Trustee a letter concluding whether or
          not the winning bid is a fair market value bid.  The Advisor will also
          provide such letter if it is the winning bidder.  In the case where
          the Advisor or the Servicer is the winning bidder it will provide for
          market comparables and valuations in its letter.

     (h)  The Auction will stipulate the Servicer be retained to service the
          Contracts sold pursuant to the terms of the Sale and Servicing
          Agreement.

                                  Exhibit L-2
<PAGE>
 
     (i)  The Auction will stipulate that such sale and consequent termination
          of the Trust Fund must constitute a "qualified liquidation" of the
          Trust Fund under Section 860F of the Code, including the requirement
          that such liquidation take place over a period not to exceed 90 days.
          The Trustee may, in its discretion, require that the purchaser of the
          Contracts provide the Trustee with an Opinion of Counsel to that
          effect.

     The Certificates will be issued on the Closing Date pursuant to a Pooling
and Servicing Agreement dated as of November 1, 1997 (the "Agreement") among
BAFSB, as Contract Seller and Servicer, and The First National Bank of Chicago,
as Trustee.  The Certificates will represent undivided interests in a trust fund
(the "Trust Fund") consisting primarily of a pool of manufactured housing
installment sale contracts and installment loan agreements (collectively, the
"Contracts") which the Registrant will convey to the Trustee, as trustee for the
Trust Fund, on the Closing Date pursuant to the Agreement.


     In connection with this opinion, we have examined and relied upon the
following documents:

     1.  the Agreement;

     2.  the registration statement on Form S-3 (No. 333-35251) filed by the
Registrant and its co-registrant, Bank of America National Trust and Savings
Association, relating to the Publicly Offered Certificates as filed with the
Securities and Exchange Commission (the "Commission") in accordance with the
provisions of the Securities Act of 1933, as amended, and the rules and
regulations of the Commission thereunder (collectively, the "Act"), and evidence
satisfactory to us that such registration statement became effective under the
Act on October 30, 1997 (the "Registration Statement"); and

     3.  the base Prospectus dated November 10, 1997 and the Prospectus
Supplement dated November 14, 1997, in each case relating to the Publicly
Offered Certificates and filed pursuant to Rule 424(b) under the Act (such
Prospectus and Prospectus Supplement being hereinafter collectively referred to
as the "Prospectus").

     In such examination, we have assumed the genuineness of all signatures and
the authenticity of all items submitted to us as originals and the conformity
with originals of all items submitted to us as copies. In making our examination
of documents executed by entities other than the Registrant, we have assumed
that each other entity has the power and authority to execute and deliver, and
to perform and observe the provisions of such documents, and the due
authorization by each such entity of all requisite action and the due execution
and delivery of such documents by each such entity.  To the extent we have
deemed necessary and proper, we have relied upon the representations and
warranties as to facts relating to the Registrant, the Contracts, and other
matters contained in the Agreement.

     The opinions expressed herein are based upon current statutes, rules,
regulations, cases and official interpretive opinions, and cover certain items
that are not directly or definitively addressed by such authorities.

     Based upon and subject to the foregoing, we are of the opinion that:

     1.     The statements contained in the Prospectus under the heading
"Certain Federal Income Tax Consequences," to the extent they constitute matters
of law or legal conclusions with respect thereto, are correct in all material
respects, under the assumptions stated therein and under applicable law as in
effect (i) on the date of the Prospectus Supplement.

     2.     Assuming (i) the making of a valid election, (ii) compliance with
the Agreement, and (iii) compliance with applicable law, including any changes
in law, (including, but not limited to, any amendments to the Internal Revenue
Code of 1986, as amended (the "Code") or applicable Treasury Regulations
thereunder), (a) the Trust Fund will be classified for federal income tax
purposes as a "real estate mortgage investment conduit" ("REMIC") within the
meaning of Code Section 860D, (b) the Publicly Offered Certificates and the
Class B-2 Certificates will be treated collectively as the "regular interests"
in such REMIC for federal income tax purposes and (c) the Class R Certificate
will be treated as the single class of "residual interest" in such REMIC for
federal income tax purposes.


     We express no opinion herein except as to the matters set forth above.
This opinion is furnished to you solely for use in connection with the issuance
and sale of the Certificates.  We hereby consent to the filing of this letter as
an exhibit to a Current Report on Form 8-K filed by you in connection with the
Trust Fund.  In giving such consent, we do not admit and we hereby disclaim that
we come within the category of persons whose consent is required under Section 7

Changes in the assumptions may have a material impact on the information set
forth in these materials. No representation is made that any performance or

This information has been prepared in connection with the issuance of securities
representing interests in the above trust, and is based in part on information
provided by Bank of America, FSB, with respect to the expected characteristics
of the pool of manufactured housing contracts in which these securities will
represent undivided beneficial interests. The actual characteristics and
performance of the manufactured housing contracts will differ from the
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set
forth in these materials. No representation is made that any performance or
return indicated herein will be achieved. For example, it is very unlikely that
manufactured housing contracts will prepay at a constant rate or follow a
predictable pattern. This information may not be used or otherwise disseminated
in connection with the offer or sale of these or any other securities, except in
connection with the initial offer or sale of these securities to you to the

WHICH THEY ARE BASED. Additional information is available upon request. These
materials do not constitute an offer to buy or sell or a solicitation of an
offer to buy or sell any security or instrument or to participate in any
particular trading strategy. ANY SUCH OFFER TO BUY OR SELL ANY SECURITY WOULD BE
MADE PURSUANT TO A DEFINITIVE PROSPECTUS AND PROSPECTUS SUPPLEMENT PREPARED BY
THE ISSUER WHICH WOULD CONTAIN MATERIAL INFORMATION NOT CONTAINED IN THESE

INFORMATION IN RESPECT OF ANY SUCH SECURITY OFFERED THEREBY AND ANY DECISION TO
INVEST IN SUCH SECURITIES SHOULD BE MADE SOLELY IN RELIANCE UPON SUCH PROSPECTUS

representing interests in the above trust, and is based in part on information
provided by Bank of America, FSB, with respect to the expected characteristics
of the pool of manufactured housing contracts in which these securities will

performance of the manufactured housing contracts will differ from the
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set

of the pool of manufactured housing contracts in which these securities will
represent undivided beneficial interests. The actual characteristics and
performance of the manufactured housing contracts will differ from the
assumptions used in preparing these materials, which are hypothetical in nature.
Changes in the assumptions may have a material impact on the information set
forth in these materials. No representation is made that any performance or
return indicated herein will be achieved. For example, it is very unlikely that
manufactured housing contracts will prepay at a constant rate or follow a

The defined terms used and not otherwise defined in the attached BankAmerica
Manufactured Housing Contract Trust II, Series 1997-2 Computational Materials
for Classes A-1, A-2, A-3, A-4, A-5, A-6, A-7, A-8, A-9, A-IO, M, B-1, and B-2
Certificates of such Series 1997-2, shall have the meanings ascribed to them, as
follows:

"CPR" a constant prepayment rate, is utilized to project prepayments, and is the
rate at which, on an annual basis, the outstanding principal balance of
contracts declines due to liquidations, unscheduled principal payments and
repurchases.

"MHP" is known as the Manufactured Housing Prepayment curve and is the
prepayment pricing convention for manufactured housing contracts. The basic
curve is 100% MHP and equates to a ramped CPR which starts at 3.7% CPR in the
first month after origination and rises 0.1% CPR monthly to 6.0% CPR in month
24, and remains at 6.0% CPR beyond month 24. 170% MHP represents the factor by
which each monthly CPR is multiplied in order to arrive at the monthly CPR speed
for a given pool. For example, the CPR rate in month 1 assuming 170% MHP is
3.7% x 170% = 6.29% CPR, increasing by 0.17% CPR each month until the 24th month
when it reaches 10.2% CPR. The CPR rate in month 1 assuming 200% MHP is
3.7% x 200% = 7.40% CPR, increasing by 0.20% CPR each month until the 24th month
when it reaches 12.0% CPR.

"PRICE" are "flat prices" and are quoted as a percentage of par, with fractions
expressed in 32nds.

"AVG LIFE" (Weighted Average Life) refers to the average amount of time from the
date of issuance of a security until each dollar of principal of such security
is expected to be repaid to the investor. The weighted average life of a
Certificate is determined by (i) multiplying the amount of each cash
distribution in reduction of the principal balance of such Certificate by the
number of years from the date of issuance of such Certificate to the stated
Distribution Date, (ii) adding the results, and (iii) dividing the sum by the
sum of the principal cash flow (which equals the initial principal balance in a
scenario in the absence of losses) of such certificate.

"FIRST PRIN" is the first distribution date on which an investor is expected to
receive the initial distribution of principal.

"LAST PRIN" is the maturity date on which an investor is expected to receive the
final distribution of principal.

"MOD DURATION" (Modified Duration), is computed by calculating Macaulay Duration
and dividing the result by (1+ one half the yield to maturity). Modified
Duration can be used to approximate the price volatility of a bond. For example,
for a 100-basis point change in yield, a certificate with a Modified Duration of
6 would theoretically have its price change by approximately 6%. Macaulay
Duration is a measure of the weighted average term-to-maturity of a bond's cash
flows. The weights in this weighted average are the present value of each cash
flow as a percent of all the bond's cash flows. The weights in this weighted
average are the percent of all the bond's cash flows (i.e., the weights are the
present value of each cash flow as a percent of the bond's price).

                                  (continued)
 
"WAM" (Weighted Average Maturity) is calculated as a weighted average of the
remaining term to maturity of a pool's underlying manufactured home contracts,
using the balance of each manufactured home contract as the weighting factor.

"PAYMENT WINDOW" is the range, in months, during which the security is expected
to receive principal distributions.

"EXCESS INTEREST" is the amount of interest collected on nondefaulted contracts
during a collection period which exceeds the interest distribution due to the
holders of the Certificates and the Monthly Servicing Fee for the related
distribution date.

"FACTOR" is the fraction of principal outstanding as of the closing date.

"SCHEDULED FINAL MATURITY" is the final scheduled distribution date for
certificateholders.  The final scheduled distribution dates for the Class A-9,
M, and B-2 were determined by adding six months to the latest possible maturing
contract. The final scheduled distribution dates for Class A-1 through A-8, and
Class B-1 were determined based on the assumption that there are no prepayments,
the Servicer does not exercise its optional termination right and the Contracts
are not sold in an auction sale.

"LAND-HOME CONTRACT OR LAND-IN-LIEU CONTRACT" is a contract secured by either
first mortgages or deeds of trust, depending upon the prevailing practice in the
state in which the underlying property is located.
