the Contract Sellers or as provided in Section 9 hereof (such date, location and
time of delivery and payment for the Offered Certificates being herein called
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 Sellers 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 Sellers in
writing not less than three full business days in advance of the Closing Date.

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

                                       5

     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.  Each 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
     such Contract Seller from the sale of such Offered Certificates, and such
     other information as the Underwriters and the Contract Sellers 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 amendment 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 such 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.  Such
     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, it 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 Sellers contained
herein as of the date hereof and the Closing Date, the accuracy of the
statements of the Contract Sellers made in any officer=s certificate pursuant to
the provisions hereof, the performance by the Contract Sellers of their
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 Sellers, 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) Each 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

                                       8
<PAGE>
 
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.

          (c) The Underwriters shall have received from Orrick, Herrington &
     Sutcliffe LLP, counsel for the Contract Sellers, 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 Sellers 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 Sellers 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 Sellers, enforceable against each such 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 Sellers.

          (v)  The Offered Certificates, when executed and authenticated in
               accordance with the terms of the Agreement and delivered to and
               paid for by the Underwriters in accordance with this Underwriting
               Agreement, will be duly and validly issued and outstanding and
               will be entitled to the benefits of the

                                       9
<PAGE>
 
               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 Sellers in the Agreement, the 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 Sellers 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 violate any statute
               currently applicable to it, or to such counsel's knowledge, any
               rule or regulation currently 

                                       10
<PAGE>
 
               applicable to it of any regulatory body, administrative agency or
               governmental body having jurisdiction over it; provided, however,
                                                              --------  -------
               no opinion will be expressed therein with respect to any consent,
               approval, authorization, order, registration or qualification
               required by, or any conflict with or violation of, any statute,
               rule or regulation applicable to BAFSB because of its status as a
               federal savings bank or to Bank of America because of its status
               as a national banking association, as to which the Underwriters
               will receive a separate in-house opinion.

          (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) the 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.

     In addition, Orrick, Herrington & Sutcliffe, LLP shall state that they have
participated in conferences with your representatives and with representatives
of the Contract Sellers 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 Sellers, a favorable opinion, dated the Closing
     Date and 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, Bank of America is duly organized and validly existing as a
          national banking association in good standing under the federal laws
          of the United States, and each 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 and Bank
          of America.

                (iii) The issuance and sale of the Offered Certificates to
          the Underwriters, the compliance by BAFSB and Bank of America with the
          other provisions of the Agreement and this Underwriting Agreement, and
          the consummation of the other transactions therein contemplated do
          not, under any statute, regulation or rule applicable to BAFSB because
          of its status as a federal savings bank or to Bank of America because
          of its status as a national banking association, require the consent,
          approval, authorization, order, registration or qualification of or
          with any court or governmental authority; 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
          violate any statute, or to such counsel's knowledge, any rule or
          regulation currently applicable to BAFSB because of its status as a
          federal savings bank or to Bank of America because of its status as a
          national banking association.

                                       12
<PAGE>
 
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
either BAFSB or Bank of America 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 either BAFSB or Bank of America 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 either BAFSB or Bank of America 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 or Bank of America 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 or Bank of America.

                  (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 either BAFSB
          or Bank of America 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 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 Sellers),
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 Contract Sellers 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 Contract
     Sellers' rights in such Contracts and the proceeds thereof.  Such security
     interest will be perfected upon the due and

                                       13
<PAGE>
 
     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 either Contract Seller 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 either Contract Seller 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
     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.

          (g) The Underwriters shall have received from Orrick, Herrington &
     Sutcliffe LLP reasonably satisfactory to the Underwriters, a favorable
     opinion, dated the Closing Date and satisfactory in form and substance to
     counsel for the Underwriters, to the effect that the Trust Fund will be
     treated as a REMIC for Illinois tax purposes and will not be subject to
     Illinois income or franchise tax other than such tax, if any, as may be
     imposed on amounts taxable for federal income tax purposes.

          (h) The Underwriters shall have received from Brown & Wood llp,
     counsel for the Underwriters, a favorable opinion, dated the Closing Date
     and satisfactory in form and substance to the Underwriters.

          (i) The Underwriters shall have received from Ernst & Young certified
     public accountants, a letter dated the Closing Date and satisfactory in
     form and substance to the Underwriters and counsel for the Underwriters, to
     the effect that they have performed certain specified procedures, as a
     result of which they determined that the information of an accounting,
     financial or statistical nature set forth in the Base Prospectus under the
     headings "The Sellers" and "Prepayment and Yield Considerations"and in the
     Prospectus Supplement under the headings "The Sellers" and "Prepayment and
     Yield Considerations" agrees with the records of the Contract Sellers or
     the Servicer, as the case may be.

                                       14

          (j) The Underwriters shall have received from Ernst & Young certified
     public accountants, a letter dated the Closing Date and satisfactory in
     form and substance to the Underwriters and counsel for the Underwriters, to
     the effect that they have performed certain specified procedures and
     computations, as a result of which they have determined that the
     information of an accounting, financial or statistical nature set forth in
     the Prospectus Supplement under the headings "The Contract Pool," "The
     Sellers" and "Prepayment and Yield Considerations" agrees with such
     computations.

          (k) The Underwriters shall have received (i) from Moody's Investors
     Service, Inc., a rating letter assigning a rating of Aaa to the Class A
     Certificates, a rating of at least Aa3 to the Class M Certificates, a
     rating of at least Baa2 to the Class B-1 Certificates and a rating of at
     least Ba2 to the Class B-2 Certificates; and (ii) from Fitch IBCA, Inc., a
     rating letter assigning a rating of AAA to the Class A Certificates, a
     rating of at least AA- to the Class M Certificates, a rating of BBB to the
     Class B-1 Certificates and a rating of BB to the Class B-2 Certificates,
     which ratings shall not have been withdrawn.

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

                  (i)  The Trustee (a) is a national banking association duly
          organized, validly existing and in good standing under the laws of the
          State of Illinois and the laws of the United States, (b) is duly
          qualified to exercise corporate trust powers under the laws of the
          United States and (c) is duly eligible and qualified to act as Trustee
          under the Agreement.

                  (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
          IV, Senior/Subordinate Pass-Through Certificates, Series 1998-1.

                 (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

                                       15
<PAGE>
 
          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.

                  (v)  The actions required of the Trustee under the Agreement,
          the consummation of any other transactions contemplated in the
          Agreement and the fulfillment of the terms of the Agreement do not
          conflict with or result in a breach or violation of any term or
          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 Sellers, the Servicer and the Trustee, and
          assuming the Trustee's receipt of the initial trust estate referenced
          in Section 2.01 of the Agreement, a trust has been duly 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.

          (m) There shall not have been any material adverse change in either
     Contract Seller's business, operations, financial condition, properties or
     assets since the date of its latest quarterly financial statement, which
     change would have a material adverse effect on its ability to perform its
     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 

                                       16
<PAGE>
 
because of any refusal, inability or failure on the part of the Contract Sellers
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 Sellers 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 Sellers, jointly and severally, 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 Sellers 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
furnished to the Contract Sellers 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 each Contract Seller and their respective directors, officers,
agents and employees against any losses, claims, damages, or liabilities to
which such Contract Seller or director, officer, agent or employee thereof may
become subject, under the 

                                       17
<PAGE>
 
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 Sellers by you, or by such
Underwriter through you, specifically for use therein, and will reimburse each
Contract Seller and their 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 Sellers and their 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 March __, 1998 and such
Underwriter shall in each case reimburse the Contract Seller and its 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 Sellers 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 Sellers 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; back-

                                       18
<PAGE>
 
ground 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 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; 

                                       19
<PAGE>
 
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 Sellers 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 Sellers 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 Sellers 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 Sellers 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 untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Contract Sellers, 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 Sellers, 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 

                                       20
<PAGE>
 
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 Sellers under this Section 8 shall
be in addition to any liability which the Contract Sellers 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 Sellers (including any person who, with his consent, is named in the
Registration Statement as about to become a director of either Contract Seller),
to each officer of either Contract Seller who has signed the Registration
Statement and to each person, if any, who controls either 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 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 Sellers 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 Sellers
shall not be under any liability to any Underwriter 

                                       21
<PAGE>
 
(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 Sellers (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 Sellers 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 Sellers, 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 Sellers 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
                  ------------------------------------------                 
agreements, representations, warranties, indemnities and other statements of the
Contract Sellers or their 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 Sellers 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
                  -------

terms of this Agreement. The parties also intend and agree that BAFSB shall be
deemed to have granted to the Trustee, and BAFSB does hereby grant to the
Trustee, a perfected first-priority security interest in (i) all of its right,

for the benefit of the creditors under such Contracts, (iii) all documents

parties intend and agree that this Agreement shall constitute a security
agreement under applicable law. If the trust created by this Agreement
terminates prior to the satisfaction of the claims of any Person under any
Certificates, the security interests 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.

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
related Contract Seller's obligations in respect thereof in Section 3.05. The
Trustee and the Contract Sellers agree to take whatever action is necessary to
enable the Servicer to fulfill its obligations as set forth in this Section
2.02(a).

otherwise.

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

the case of BAFSB), duly organized, validly existing and in good standing under
the laws of the United States, and it has the corporate power to own its assets
and to transact the business in which it is currently engaged. It is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction in which its type of organization and the character of the
business transacted by it or properties owned or leased by it requires such
qualification and in which the failure so to qualify would have a material
adverse effect on the business, properties, assets, or condition (financial or
other) of such Contract Seller. It was properly licensed in each jurisdiction at
the time of purchase or origination of each Contract originated or purchased on
an individual basis by it in such jurisdiction to the extent required by the
laws of such jurisdiction as applied to the purchase or origination and
servicing of such Contract, except where the failure to be so licensed does not
materially adversely affect the interests of the Trust Fund or the
Certificateholders in and to such Contract.

     (b)  Authorization; Binding Obligations.  It has the power and authority to
          ----------------------------------                                    
make, execute, deliver and perform this Agreement and all of the transactions
contemplated under this Agreement, and has taken all necessary corporate action
to authorize the execution, delivery and performance of this Agreement. When
executed and delivered, this Agreement will constitute the legal, valid and
binding obligation of such Contract Seller enforceable in accordance with its
terms, except as enforcement of such terms may be limited by bankruptcy,
insolvency or similar laws affecting the enforcement of creditors' rights
generally and by the availability of equitable remedies.

     (c)  No Consent Required.  It is not required to obtain the consent of any
          -------------------     
other party or any consent, license, approval or authorization from, or

in connection with the execution, delivery, performance, validity or
enforceability of this Agreement, except such as have been obtained or where the
failure to obtain any such consent, license, approval or authorization, or to
make any registration or declaration does not materially adversely affect the
interests of the Trust Fund or the interests of the Certificateholders therein.

     (d)  No Violations.  The execution, delivery and performance of this 
          -------------     
Agreement by such Contract Seller will not violate any provision of any existing
law or regulation or any order or decree of any court applicable to such
Contract Seller or the charter or bylaws of such Contract Seller, or constitute
a material breach of any mortgage, indenture, contract or other agreement to
which such Contract Seller is a party or by which such Contract Seller may be
bound except where such violation or breach does not materially adversely affect
the interests of the Trust Fund or the interests of the Certificateholders
therein.

          -------------------------      
will not change its name, identity or structure or relocate its chief executive
office without first giving written notice to the Trustee. If any change in such
Contract Seller's name, identity or structure or the relocation of its chief
executive office would make any financing or continuation statement or notice of
lien filed under this Agreement seriously misleading within the meaning of
applicable provisions of the UCC or any title statute, such Contract Seller, no
later than five days after the effective date of such change, shall file such
amendments as may be required to preserve and protect the Certificateholders'
interests in the Contracts and proceeds thereof and in the Manufactured Homes
and the Mortgaged Properties.

     (d)  No Defenses.  The Contract is not subject to any right of rescission,
          -----------                                                          
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
subject to any right of rescission, setoff, counterclaim or defense, including
the defense of usury, and no such right of rescission, setoff, counterclaim or
defense has been asserted with respect thereto.

          ---------            
a Hazard Insurance Policy in the amount required by Section 4.09. All premiums
due as of the Closing Date on such insurance have been paid in full to the
applicable providers of such insurance.

     (f)  Origination.  To the knowledge of such Contract Seller, the Contract
          -----------          
was either (i) originated by a manufactured housing dealer acting in the regular
course of its business, and purchased on an individual basis by BAFSB, acting
through its division, BankAmerica Housing Services or (ii) originated by BAFSB,
acting through its division, BankAmerica Housing Services, in the ordinary
course of its business.

     (g)  Lawful Assignment.  The Contract was not originated in and is not 
          -----------------         
subject to the laws of any jurisdiction whose laws would make the transfer of
such Contract from such Contract Seller to the Trust Fund under this Agreement
unlawful.

     (h)  Compliance with Law.  All requirements of any federal, state or local
          -------------------        
law, including usury, truth-in-lending and equal credit opportunity laws and

          -----------------                
subordinated in whole or in part or rescinded, the Manufactured Home securing
the Contract has not been released from the lien of the Contract in whole or in
part and, in the case of a Land Home Contract, the related Mortgaged Property
has not been released from the related Mortgage.

     (j)  Valid Security Interest.  The Contract, other than any Land Home 
          -----------------------        
Contract, creates a valid, subsisting and enforceable first-priority security
interest in favor of BankAmerica Housing Services as secured lender, or agent
thereof, in the Manufactured Home covered thereby; such security interest has
been assigned by such Contract Seller as secured lender to the Trustee in
accordance with the terms herein and; the Trustee has a valid and perfected
first-priority security interest in such Manufactured Home. Each Mortgage is a
valid first lien in favor of BankAmerica Housing Services on real property
securing the amount owed by the Obligor under the related Land Home Contract
subject only to (a) the lien of current real property taxes and assessments, (b)
covenants, conditions and restrictions, rights of way, easements and other
matters of public record as of the date of recording of such Mortgage, such
exceptions appearing of record being acceptable to mortgage lending institutions
generally in the area wherein the property subject to the Mortgage is located or
specifically reflected in the appraisal obtained in connection with the
origination of the related Land Home Contract obtained by BankAmerica Housing
Services and (c) other matters to which like properties are commonly subject
which do not materially interfere with the benefits of the security intended to
be provided by such Mortgage. The applicable Contract Seller has assigned all of
its right, title and interest in such Land Home Contract and related Mortgage,
including the security interest in the Manufactured Home covered thereby, to the
Trustee. The Trustee has and will have a valid and perfected and enforceable
first priority security interest in such Land Home Contract.

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

          ----------                                                          
thereof, without knowledge that the Contract was subject to any security
interest. It has not sold, 

                                      -29-
<PAGE>
 
assigned or pledged the Contract to any Person other than the Trust Fund, and
prior to the transfer of the Contract by such Contract Seller to the Trust Fund,
it had good and marketable title thereto free and clear of any encumbrance,
equity, loan, pledge, charge, claim or security interest and was the sole owner
thereof with full right to transfer the Contract to the Trust Fund.

     (m)  No Defaults.  As of the Cut-Off Date, there was no default, breach,
          -----------                                                        
violation or event permitting acceleration existing under the Contract and to
its knowledge, no event which, with notice and the expiration of any grace or
cure period, would constitute such a default, breach, violation or event
permitting acceleration under such Contract (except payment delinquencies
permitted by clause (a) above). Such Contract Seller has not waived any such
default, breach, violation or event permitting acceleration.

     (n)  No Liens.  As of the Closing Date, there are, to its knowledge, no 
          --------              
claims which have been filed for work, labor or materials affecting the
Manufactured Home or any related Mortgaged Property securing the Contract which
are or may be liens prior to, or equal or coordinate with, the lien of the
Contract.

     (o)  Equal Installments.  The Contract has a fixed Contract Rate and 
          ------------------                                      
provides for level monthly payments of principal and interest which fully
amortize the loan over its term. The scheduled monthly payment allocable to
interest on the Contract is calculated on the basis that each scheduled monthly
payment is applied on its Due Date, regardless of when it is actually made.

     (p)  Enforceability.  The Contract contains customary and enforceable 
          --------------         
provisions such as to render the rights and remedies of the holder thereof
adequate for the realization against the collateral of the benefits of the
security.

     (q)  Contract Schedule.  The information set forth in Exhibit A-1 to the
          -----------------                                                  
Contract Schedule (in the case of BAFSB) and Exhibit A-2 to the Contract
Schedule (in the case of Bank of America) is true and 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.

     (s)  Loan-to-Value Ratio.  At the time of its origination, such Contract 
          -------------------                         
had a Loan-to-Value Ratio (rounded to the nearest 1%) not greater than 95%.

     (t)  Not Real Estate.  With respect to each Contract other than a Land Home
          ---------------                                                       
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
located under the laws of the jurisdiction in which it was located at the time
the related Contract was executed by the parties thereto, and with respect to
each Contract including Land Home Contracts the related Manufactured Home is, to
such Contract Seller's knowledge, free of damage (including earthquake or
hurricane damage) and in good repair.

     (u)  Notation of Security Interest.  With respect to each Contract other 
          -----------------------------        
than a Land Home Contract, if the related Manufactured Home is located in a
state in which notation of a 

                                      -30-
<PAGE>
 
security interest on the title document is required 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 being applied for, such title
document will be issued within 180 days and will show, BankAmerica Housing
Services 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 BankAmerica Housing Services
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 BankAmerica
Housing Services 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 related Contract
Seller and any trustee in bankruptcy of BankAmerica Housing Services) 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.

     (v)  Secondary Mortgage Market Enhancement Act.  The related Manufactured
          -----------------------------------------      
Home is a "manufactured home" within the meaning of 42 United States Code,

          ----------------------------       
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)
the time the Contract is transferred to the Trust Fund. Each Contract is a
"qualified mortgage" under Section 860G(a)(3) of the Code.

Section 3.05    REPURCHASES OF CONTRACTS OR SUBSTITUTION OF CONTRACTS FOR BREACH
                ----------------------------------------------------------------
OF REPRESENTATIONS AND WARRANTIES.
- --------------------------------- 
     (a)  Each Contract Seller shall either (i) repurchase a Contract sold by it
to the Trust Fund at such Contract's Repurchase Price, or (ii) if such Contract
Seller is able to satisfy the conditions of Section 3.05(b), remove such
Contract from the Trust Fund and substitute therefor an Eligible Substitute
Contract in accordance with and subject to the limitations of Section 3.05(b),
in each case within 90 days after such Contract Seller becomes aware, or
receives written notice from the Servicer or the Trustee, of a breach of a
representation or warranty of such Contract Seller set forth in Section 3.02 or
3.03 of this Agreement that materially adversely affects the Trust Fund's
interest in such Contract, unless such breach has been cured; provided, however,
                                                              --------  ------- 
that with respect to any Contract incorrectly described on the Contract Schedule
with respect to remaining principal balance, which such Contract Seller would
otherwise be required to repurchase pursuant to this Section 3.05, such Contract
Seller may, in lieu of repurchasing such Contract, deposit in the Certificate
Account not later than one Business Day after such Determination Date cash in an
amount sufficient to cure such deficiency or discrepancy; and further provided,
                                                              ------- --------
that with respect to a breach of a representation or warranty relating to the
Contracts in the aggregate and not to any particular Contract, a 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 a Contract Seller is
- ------- --------                                                      
required to repurchase, such 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 imposition of a tax under
the applicable REMIC Provisions. It is understood and agreed that the obligation
of either 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 such Contract Seller shall
                           --------  -------                           
defend and indemnify the Trustee, the Certificate Administrator, the Trust Fund
and 

                                      -33-
<PAGE>
 
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 either 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 related Contract Seller and need not be deposited in the Certificate Account.

          Notwithstanding the foregoing, no Contract Seller shall 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 either 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 a 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), no
Contract Seller shall 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 related 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 such 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 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 

                                      -34-
<PAGE>
 
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, either 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 such 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 related 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 such Contract Seller as debtor and naming
     the Trustee as secured party and listing such Contract as collateral;

          (iii) the related 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 such 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 related Contract Seller to the Trustee; and 

          (iv)  if the Scheduled Principal Balance of such Replaced Contract is
     greater than the Scheduled Principal Balance of such Contract, the related
     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 

                                      -35-
<PAGE>
 
to be accomplished). Such substitution shall be effected prior to the first
Determination Date that occurs more than 90 days after the related 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 related Contract Seller and are
reasonably necessary to reconvey the repurchased Contract or Replaced Contract,
as the case may be, to the related 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 related 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 Sellers to the Trustee and shall inure to the benefit of the Trustee.

         (b)  Any cause of action against either 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 either Contract Seller or notice thereof by the
Trustee or Servicer to such Contract Seller, (ii) failure by the related
Contract Seller to cure such breach, and (iii) demand upon the related 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.

                                      -37-
<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 IV, Senior/Subordinate Pass-Through Certificates, Series
1998-1, 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);

                                      -38-
<PAGE>
 
          (2)  All Net Liquidation Proceeds;

          (3)  All amounts required to be deposited by either 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;

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

          (7)  All Deficiency Amounts.

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 and, where
permitted by applicable law, any Deficiency at its own expense, in its own name,
if possible, or as agent for the Contract Owner 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 

                                      -39-
<PAGE>
 
enforce the Contract, the Trustee on behalf of the Certificateholders shall, at
the Servicer's expense, take such steps as the Servicer deems necessary 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 

                                      -40-
<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 Sellers, 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 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 

                                      -41-
<PAGE>
 
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 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.

                                      -42-
<PAGE>
 
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
related 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 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  

                                      -43-
<PAGE>
 
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 (other than 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 (other than Land Home Contract Files) as custodian therefor.

                                      -44-
<PAGE>
 
     (b)  The Servicer agrees to maintain the related Contract Files (other than
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 (other than 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 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 on the Servicer's premises and the receipting for Contract 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 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 as herein provided, and shall promptly take appropriate
     action to remedy any such failure. In acting as custodian of the Contract
     Files, the Servicer further agrees not to assert any beneficial ownership
     interests in the Contracts or the 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; provided, however, that the Servicer will not be liable for any
            --------  -------                                              
     portion of any such amount resulting from the negligence or willful
     misconduct of any other Person.

     (e)  Not later than 60 days from the Closing Date, each Contract Seller
shall deliver, or cause to be delivered, to the Trustee the following:

          (i)   The Land Home Contract Files;

          (ii)  The original Land Home Contract endorsed as provided in Section
     3.02(x) (which endorsement may be manual or facsimile signature) on behalf
     of the applicable Contract Seller; and

                                      -45-
<PAGE>
 
          (iii)  an Assignment from BAFSB (on behalf of the applicable Contract
     Seller) to the Trustee, which Assignment shall be in form and substance for
     recording, but shall not be recorded except as required by Section 4.22
     below;

Notwithstanding anything to the contrary contained in this Section 4.16(e), in
those instances where the public recording office retains the original Mortgage,
the Assignment of the Mortgage or the intervening Assignments of the Mortgage
after it has been recorded, the related Contract Seller shall be deemed to have
satisfied its obligations hereunder upon delivery to the Trustee of a copy of
such Mortgage, such Assignment or Assignments of Mortgage certified by the
public recording office to be a true copy of the recorded original thereof.

     Within 90 days following the Closing Date, the Trustee shall review each
Land Home Contract File to determine that all required documents set forth in
each item of the first paragraph of this Section 4.16(e) have been executed and
received and that such documents relate to the Land Home Contracts identified on
the Contract Schedule.  For purposes of this determination, the Trustee may rely
on the purported due execution and genuineness of any signature thereon.  If
within such 90 day period the Trustee finds that any document constituting a
part of a Land Home Contract File was not executed, defective or received or is
unrelated to the Land Home Contracts identified in the Contract Schedule (in
this Section 4.16(e), a "defect"), the Trustee shall promptly upon the
conclusion of its review notify the Servicer and the Servicer shall notify the
related Contract Seller.  The related Contract Seller shall have a period of 90
days from receipt of such notice within which to correct or cure any such defect
after the Contract Seller has been notified of such.  If the Contract Seller
cannot correct or cure any such defect with respect to a Land Home Contract
within such 90 day period, it shall comply with the provisions of Section 3.05
hereof.

     If recordation of any Assignment is required hereunder, the original of
each such recorded Assignment shall be delivered to the Trustee within 10 days
following the date on which it is returned to the Contract Seller by the office
with which such Assignment was filed for recordation.  Upon receipt by the
Trustee of the recorded Assignment, such recorded Assignment shall become part
of the Land Home Contract File.

     (f) Custodial Arrangements.  The Trustee may appoint a custodian who is
         ----------------------                                             
acceptable to the Servicer and each Contract Seller and who, upon execution of a
custodial agreement, shall maintain possession of the Land Home Contract Files,
or such part of them as the Trustee shall direct, as agent of the Trustee
pursuant to the terms of such custodial agreement. The appointment of such
custodian shall not relieve the trustee of its obligations hereunder.

     The Trustee shall keep the Servicer apprised at all times after the Closing
Date of the location of the Land Home Contract Files.  The Trustee shall take
all steps that are reasonably necessary or appropriate in order to facilitate
the Servicer's access to the Land Home Contract Files during normal business
hours of the Trustee or any custodian and shall cooperate fully with the
Servicer in securing such access.

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 

                                      -46-
<PAGE>
 
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 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.

                                      -47-
<PAGE>
 
     (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 Sellers, 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 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.

                                      -48-
<PAGE>
 
     (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 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.

                                      -49-
<PAGE>
 
     (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 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.

                                      -50-
<PAGE>
 
     (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
Contract becomes a Liquidated Contract.

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 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) 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 

                                      -52-

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 either Contract Seller
in obtaining any information maintained by it in the ordinary course of
performing its duties hereunder that is necessary for either 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 each 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 commencing in 1999, 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 each 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 Sellers, 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.

that a Contract Seller is no longer assigned a long-term senior debt rating from
Moody's of Baa3 or higher, from BBB- or higher from Fitch, 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 or a Contract Seller that a Contract Seller
does not have a long-term senior debt rating from Moody's of Baa3 or higher,
from BBB- or higher from Fitch, or an equivalent rating from any nationally
recognized statistical rating organization, or if the Trustee otherwise becomes

                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 Class A Certificateholders, the Class A Interest
     Distribution Amount;

          (ii) to the Class A Certificateholders, the Formula Principal
     Distribution until the Class A Certificate Balance has been reduced to
     zero;

                                      -55-
<PAGE>
 
          (iii)  to the Class M Certificateholders, the Class M Interest
     Distribution Amount;

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

          (v)    to the Class B-1 Certificateholders, the Class B-1 Interest
     Distribution Amount;

          (vi)   to the Class B-1 Certificateholders, 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 Formula Principal
     Distribution Amount until the Class B-2 Certificate Balance is reduced to
     zero;

          (ix)   to the Reserve Account any remaining Available Distribution
     Amount until the amount on deposit therein equals the Reserve Account Cap;

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

     Furthermore, notwithstanding the foregoing, if the Formula Principal
Distribution Amount allocable to the Holders of the Class A Certificates on any
Distribution Date pursuant to clause (ii) above exceeds the Class A Certificate
Balance for such Distribution Date, such excess will be distributed to the Class
M Certificateholders.  If 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. If the
Formula Principal Distribution Amount allocable to the Class B-1
Certificateholders on any Distribution Date pursuant to clause (vi) above
exceeds the Class B-1 Certificate Balance for any such Distribution Date, such
excess will be distributed to the Class B-2 Certificateholders.

     Such distributions to the Class A 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 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 Certificates and the Class A Distribution Amount for
such Distribution Date, (b) 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, (c) 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 (d) 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 

                                      -56-

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
Sellers 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 B-2, Exhibit B-3, Exhibit B-4 and Exhibit C (reverse of
- ----------   -----------  -----------  -----------     ---------
Certificates) hereto.

Section 5.03    Permitted Withdrawals from the Certificate Account.
                -------------------------------------------------- 

     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 related 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 such Contract
     Seller;

          (ii) to reimburse itself for the payment of taxes or charges out of
     Liquidation Proceeds (to the extent not previously retained from such
     Liquidation Proceeds prior to

                                      -57-
<PAGE>
 
     their deposit) or out of payments expressly made by the related Obligor to
     reimburse the Servicer for such taxes or charges, as permitted by Section
     4.06;

          (iii) to pay to itself the Monthly Servicing Fee and Servicer
     Deficiency Amounts and Repossession Profits, if any;
 
          (iv)  to reimburse itself or a previous Servicer out of Liquidation
     Proceeds (to the extent not previously retained from Liquidation Proceeds
     prior to their deposit in the Certificate Account) in respect of a
     Manufactured Home and out of payments by the related Obligor (to the extent
     of payments expressly made by the Obligor to reimburse the Servicer for
     insurance premiums) for expenses incurred by it in respect of such
     Manufactured Home that are specified as being reimbursable to it pursuant
     to Section 4.07, 4.09, or 4.13 or to a previous Servicer under Section
     7.07;

          (v)   to reimburse itself for any Nonrecoverable Advances and for
     Monthly Advances in respect of Liquidated Contracts, in each case, in
     accordance with Section 5.01(c);

          (vi)  after the Class A Certificate Balance, Class M Certificate
     Balance, Class B-1 Certificate Balance, and Class B-2 Certificate Balance
     have been reduced to zero, to reimburse the Servicer and the REMIC
     Administrator, pro rata, for expenses incurred and reimbursable to the
     Servicer pursuant to Section 7.05 and to the REMIC Administrator pursuant
     to Section 4.17(c); and

          (vii) to withdraw any amount deposited in the Certificate Account
     that was not required to be deposited therein (including any collections on
     the Contracts that, pursuant to Section 2.01(a), are not part of the Trust
     Fund).

     Since, in connection with withdrawals pursuant to clauses (i), (ii) and
(iv) of this Section 5.03, the Servicer's entitlement thereto is limited to
collections or other recoveries on the related Contract, the Servicer shall keep
and maintain separate accounting, on a Contract by Contract basis, for the
purpose of justifying any withdrawal from the Certificate Account pursuant to
such clauses.

portion thereof during which such Person was a Certificateholder. Such
obligation of the Servicer shall be deemed to have been satisfied to the extent

pursuant to any requirements of the Code as from time to time in force. On each
Distribution Date, the Servicer shall forward or cause to be forwarded by mail

during the calendar year was a Holder of a Class R Certificate a statement
containing the applicable distribution information provided pursuant to this
Section 5.07 aggregated for such calendar year or applicable portion thereof
during which such Person was a Holder of a Class R Certificate.  Such obligation
of the Servicer shall be deemed to have been satisfied to the extent that
substantially comparable information shall be provided by the Servicer pursuant
to any requirements of the Code.  A Certificate Owner holding Certificates of a
Class representing in the aggregate at least 5% of the Percentage Interests of

Section 5.08    Reserve Account.
                --------------- 
     (a)  On the Closing Date, the Trustee shall establish and maintain the
Reserve Account titled "[Trustee] in trust for registered holders of BankAmerica
Manufactured Housing Contract Trust IV, Senior/Subordinate Pass-Through
Certificates, Series 1998-1" as part of the Trust Fund for the benefit of the
Certificateholders as described herein. The Contract Sellers shall cause the
Reserve Account to have an initial balance of $8,954,401.00 on or prior to the
Closing Date. To the extent funds on deposit in the Reserve Account fall below
the Reserve Account Cap, the Reserve Account will be replenished from time to
time in accordance with clause (ix) of Section 5.02(a). On each Distribution
Date, the Trustee, based upon information in the Monthly Report, shall withdraw
the Reserve Account Draw Amount, if any, from the Reserve Account and deposit it
in the Certificate Account. Any Reserve Account Draw Amount shall be applied
pursuant to Section 5.02. After giving effect to the withdrawal of the Reserve
Account Draw Amount, if any, for a Distribution Date, the excess, if any, of the
amount on deposit in the Reserve Account over the Reserve Account Cap shall be
distributed to the Class R Certificateholders.

     (b)  Amounts held in the Reserve Account shall be invested by the Trustee
in Eligible Investments in the name of the Trustee, as Trustee, maturing, or in
the case of a money market fund redeemable (without premium or penalty) not
later than one Business Day prior to the next succeeding Distribution Date
(except that if such Eligible Investment is an obligation of the 

                                      -64-
<PAGE>
 
institution that maintains the Reserve Account, then such Eligible Investment
shall mature, or in the case of a money market fund shall be redeemed, not later
than such Distribution Date) and shall not be sold or disposed of prior to its
maturity. All net income and gain, if any, from any such investments in respect
of a Distribution Date shall be paid to the Holders of the Class R Certificates.

provided, that one Class B-2 Certificate will have a denomination representing
the remainder of the Initial Class B-2 Certificate Balance.

     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 Sellers or any Affiliate thereof.

                                      -66-

     The Contract Sellers 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 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 Sellers or the Servicer, shall be required to provide
to the Trustee, the Contract Sellers and the Servicer, an investment letter
substantially the forms set forth in Exhibit H (the "Transferor Certificate"),
                                     --------- 
with respect to the Class B-2 Certificates, and either Exhibit J (the
                                                       ---------
"Investment Letter") or Exhibit K (the "Rule 144A Letter") or as otherwise
                        ---------
acceptable to the Contract Sellers. 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 Sellers 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 Sellers, the Servicer or the Trustee. The Contract Sellers 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 

                                      -67-
<PAGE>
 
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 Sellers in providing the Rule
144A information referenced in the preceding sentence, including providing to
the Contract Sellers such information regarding the Certificates, the Contracts
and other matters regarding the Trust Fund as either Contract Sellers 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 Sellers 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 Sellers or the Servicer, acceptable to and in form and
substance satisfactory to the Trustee, the Contract Sellers 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 Sellers 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 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 Certificate 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 

                                      -68-
<PAGE>
 
     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.

          (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

                                      -69-
<PAGE>
 
     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:
 
          (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.

     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 Sellers 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 Sellers 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 Sellers, 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 Sellers 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, 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 Sellers.  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 

                                      -71-
<PAGE>
 
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, 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;

     (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
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.

<PAGE>
 
     If, after Global Certificates have been issued with respect to Class A,
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 BAFSB is unable to locate a qualified
successor, (b) BAFSB, at its sole option, advises the Trustee that it elects 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 Sellers 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
Sellers or the Servicer 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 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 SELLERS 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 Sellers, 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 Sellers, 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 Sellers 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 Sellers
of, any such Contract.

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

     Indemnification under this Article VII shall include reasonable fees and

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 Sellers or the Servicer.
                --------------------------------------------------------------- 

     The Contract Sellers 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 Sellers or the Servicer may be merged or
consolidated, or any corporation or association resulting from any merger,
conversion or consolidation to which the Contract Sellers or the Servicer shall
be a party, or any Person 

                                      -74-

succeeding to the business of the Contract Sellers or the Servicer, shall be the
successor of the Contract Sellers 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 Section 7.07 with respect to the qualifications of a
successor to the Servicer. The Contract Sellers 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 Sellers, the Servicer
                -------------------------------------------------------------
and Others.
- ---------- 

     Neither the Contract Sellers, 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 Sellers 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 Sellers, 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 Sellers 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.
                ---------------------- 

     Notwithstanding any provision to the contrary in this Agreement (i) without
the consent of the Trustee or any Certificateholder, the Servicer may, with the
prior written consent of the Contract Sellers, which consent shall not be
unreasonably withheld, assign its rights and delegate its duties and obligations
under this Agreement, including, but not limited to, a purchaser of BAFSB's Bank
America Housing Services division from BAFSB by a third party; provided that the
                                                               --------         
Person accepting such assignment or delegation shall be a Person which is
satisfactory to the Contract Sellers, in their respective sole judgment, shall
be willing to service the Contracts, and shall execute and deliver to the
Contract Sellers and the Trustee an agreement, in form and substance reasonably
satisfactory to the Contract Sellers, 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 

                                      -75-
<PAGE>
 
that the Servicer shall remain liable for all liabilities and obligations
incurred by it as Servicer hereunder prior to the satisfaction of the conditions
to such assignment and in delegation.

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 Sellers, 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 Sellers 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 the Certificates. Any assignment by or termination of the Servicer pursuant
to Section 7.06 or 

                                      -76-
<PAGE>
 
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 Sellers or
to the Servicer, the Trustee and the Contract Sellers 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 Sellers or to the
Servicer, the Trustee and the Contract Sellers 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 Default to each Rating Agency and the
Contract Sellers. On or after the receipt by the Servicer of 

                                      -78-
<PAGE>
 
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 the Contract Sellers, the
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.

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

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

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 duties as Trustee hereunder or in the
exercise of any of its rights or powers if there is reasonable 

                                      -81-
<PAGE>
 
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;

     (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
           --------  -------  

                                      -82-
<PAGE>
 
Affiliate of the Contract Sellers 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 Sellers 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 Sellers 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 Sellers 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 Sellers or the
Servicer in respect of the Contracts or deposited in or withdrawn from the
Certificate Account by the Contract Sellers 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 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 

                                      -83-
<PAGE>
 
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 Sellers, 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 Sellers; 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 Sellers, the Servicer
and each Rating Agency.  Upon receiving such notice of resignation, the Contract
Sellers 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 

                                      -84-
<PAGE>
 
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 Sellers, 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
Sellers 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 Sellers, 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 Sellers 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 Sellers and each Rating Agency.  If the
Servicer fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Contract Sellers.

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

                                      -85-
<PAGE>
 
     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, the Contract Sellers 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 Sellers 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
Sellers and the Trustee may consider necessary or desirable.  If either or the
Contract Sellers 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 (or with the applicable
Contract Seller) 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.

     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 

                                      -86-
<PAGE>
 
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 Sellers, the Servicer or the Certificateholders except when acting as
Paying Agent.  Additionally, the Certificate Administrator shall be entitled to
rely upon all directions, calculations and other information received by the
Contract Sellers, 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 

                                      -87-
<PAGE>
 
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.

                 ----------- 

     (a)  The respective obligations and responsibilities of the Contract
Sellers, the Servicer (except as to Section 9.05) and the Trustee shall

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 Unpaid Interest Shortfall, Class M Unpaid Interest Shortfall, Class B-1
Unpaid Interest Shortfall and any Class B-2 Unpaid Interest Shortfall and the
remittance of all funds due hereunder; provided, that the purchase price of such
                                       --------  
Contracts shall in no event be less than the Minimum Termination Amount (without
regard to amounts on deposit in the Reserve Account) 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

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 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. Either 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 

                                      -89-
<PAGE>
 
expenses of such counsel shall be paid by the Contract Sellers. 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 Sellers;

          (3) a financial advisor selected by the Trustee, the fees of whom
     shall be an expense of the Contract Sellers, 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 any 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
     (without regard to amounts on deposit in the Reserve Account);

          (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.

     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 

                                      -90-
<PAGE>
 
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 Sellers 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 Certificates, the Class A
     Certificate Balance together with the Class A Unpaid Interest Shortfall and
     one month's interest at the Class A Pass-Through Rate on the Class A
     Certificate Balance, (b) as to the Class M Certificates, the Class M
     Certificate Balance together with the Class M Unpaid Interest Shortfall and
     one month's interest at the Class M Pass-Through Rate on the Class M
     Certificate Balance, (c) as to the Class B-1 Certificates, the Class B-1
     Certificate Balance together with the Class B-1 Unpaid Interest Shortfall
     and one month's interest at the Class B-1 Pass-Through Rate on the 
     Class B-1 Certificate Balance and (d) as to the Class B-2 Certificates, 
     the Class B-2 Certificate Balance 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

                                      -91-
<PAGE>
 
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 Sellers and the Contract
Sellers 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 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 Sellers.

                            MISCELLANEOUS PROVISIONS

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

     This Agreement may be amended from time to time by the Contract Sellers,
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 Sellers 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 Sellers 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
Sellers, 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.

                                      -93-
<PAGE>
 
     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.

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

     evidencing a percentage interest in any distributions allocable to the
     Class B-1 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 National Trust and Savings Association and Bank of
     America, FSB, each as Contract Seller (each a "Contract Seller" and
     collectively the "Contract Sellers")

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

     Principal in respect of this Certificate is distributable monthly as set
forth herein.  Accordingly, the Certificate Balance at any time may be less than
the Certificate Balance as set forth herein.  Neither this Certificate nor the
Contracts are insured or guaranteed by either 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 Cede & Co. is the registered owner of the Percentage
Interest evidenced by this Certificate (obtained by dividing the denomination of
this Certificate by the aggregate of the denominations of all Class B-1
Certificates) in certain monthly distributions with respect to a Trust Fund
consisting of the Contracts deposited by the Contract Sellers.  The Trust Fund
was created pursuant to a Pooling and Servicing Agreement, dated as of March 1,
1998 (the "Agreement"), among the Contract Sellers, 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.

     Pursuant to the terms of the Agreement, a distribution will be made on the
10/th/ day of each month or, if such 10/th/ day is not a Business Day, the
Business Day immediately following (the "Distribution Date"), commencing on the
first Distribution Date specified above, to the Person in whose name this
Certificate is registered at the close of business on the applicable Record Date
in an amount equal to the product of the Percentage Interest evidenced by this
Certificate and the Class B-1 Distribution Amount on such Distribution Date
pursuant to Section 5.02 of the Agreement.  The Record Date applicable to each
Distribution Date is the last Business Day preceding such Distribution Date.
Distributions to the Holder of this Class B-1 Certificate shall be applied first
to interest and then to principal.

                                 Exhibit B-3-3
<PAGE>
 
     Distributions on this Certificate shall be made by wire transfer of
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
to the related Record Date and such Certificateholder shall hold Class B-1
Certificates evidencing a Percentage Interest aggregating 10% or more or, if
not, by check mailed by first class mail to the address of such
Certificateholder appearing in the Certificate Register. The final distribution
on each Certificate will be made in like manner, but only upon presentment and
surrender of such Certificate at the Corporate Trust Office or such other
location specified in the notice to Certificateholders of such final
distribution.

     No transfer of this Class B-1 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 Sellers 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 B-1 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 Sellers
or the 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.

     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.

coupons in denominations specified in the Agreement.  As provided in the
Agreement and subject to certain limitations therein set forth, Certificates are
exchangeable for new Certificates of the same Class in authorized denominations
and evidencing the same aggregate Percentage Interest, as requested by the
Holder surrendering the same.

     No service charge will be made for any such registration of transfer or
exchange, but the Trustee may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

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

     On any Distribution Date on which the Pool Scheduled Principal Balance is
less than or equal to 10% of the Cut-off Date Pool Principal Balance, the
Servicer will have the option to repurchase, upon giving notice mailed no later
than the 10th day of the month next preceding the month of the exercise of such
option, all 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 of the
Agreement), 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 (i) reimburse any Class A Unpaid Interest Shortfall,
Class M Unpaid Interest Shortfall, Class B-1 Unpaid Interest Shortfall, and any
Class B-2 Unpaid Interest Shortfall and (ii) pay one month's interest due on the
Class A, Class M, Class B-1 and Class B-2 Certificates at the applicable Pass-
Through Rates on such Classes' unpaid Certificate Balances; provided, that in no
event shall the purchase price of such Contracts be less than the Minimum
Termination Amount.

     On any Distribution Date on which the Pool Scheduled Principal Balance is
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 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 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.  

                                  Exhibit C-2
<PAGE>
 
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 Sellers 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 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 National Trust and Savings Association and Bank of
     America, FSB, each as Contract Seller (each a "Contract Seller" and
     collectively the "Contract Sellers")

which manufactured housing contracts were originated or acquired by Bank of
America, FSB ("BAFSB") or Bank of America National Trust and Savings Association
("Bank of America") respectively, 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 Seller5s, 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
Sellers.  The Trust Fund was created pursuant to a Pooling and Servicing
Agreement, dated as of March 1, 1998 (the "Agreement"), among the Contract
Sellers, 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 Sellers 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 

                                  Exhibit D-3
<PAGE>
 
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 Sellers or the 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 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 Sellers 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 Sellers, 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.

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 IV
Senior/Subordinate Pass-Through Certificates, Series 1998-1, 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.

               Senior/Subordinate Pass-Through Certificates, Series 1998-1
               -----------------------------------------------------------

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
IV Senior/Subordinate  Pass-Through Certificates, Series 1998-1, Class R (the
"Certificates"), issued pursuant to Section 6.02(c) of the Pooling and Servicing
Agreement (the "Agreement"), dated as of March 1, 1998 among Bank of America
National Trust and Savings Association as Contract Seller, Bank of America, FSB,
acting through its division, BankAmerica Housing Services as Contract Seller and
Servicer, and The 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 Sellers 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,

     having such knowledge and experience in financial and business matters,
     and, in particular, in such

     matters related to securities similar to the Certificates, such that we are

     of general advertising or in any other manner, or (e) take any other
     action, that (as to any of (a) through (e) 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.  We will not sell or otherwise transfer any of the
     Certificates, except in compliance with the provisions Agreement.

               (a) (1) are not an employee benefit or other plan subject to the

     certification to that effect attached hereto as Annex 1 or Annex 2.  We are
     aware that the sale to us is being made in reliance on Rule 144A.  We are
     acquiring the Rule 144A Securities for our own account or the accounts of
     other qualified institutional buyers, understand that such Rule 144A
     Securities may be resold, pledged or transferred only (I) to a person
     reasonably believed to be a qualified institutional buyer that purchases

          3.   We are (a) a substantial, sophisticated institutional investor
     having such knowledge and experience in financial and business matters,
     and, in particular, in such matters related to securities similar to the
     Rule 144A Securities, such that we are capable of evaluating the merits and
     risks of investment in the Rule 144A Securities, (b) able to bear the
     economic risks of such an investment and (c) an "accredited investor"
     within the meaning if Rule 501(a) promulgated pursuant to the Act.

          4.   We have not and will not nor have we authorized or will authorize
     any person to (a) offer, pledge, sell, dispose of or otherwise transfer any
     Rule 144A Securities, any interest in any Rule 144A Securities or any other
     similar security from any person in any manner, (b) solicit any offer to

     Securities, any interest in any Rule 144A Securities or any other similar
     security from any person in any manner, (c) otherwise approach or negotiate
     with respect to any Rule 144A Securities, any interest in any Rule 144A
     Securities or any other similar security from any person in any manner, (d)
     make any general solicitation by means of general advertising or in any
     other manner, or (e) take any other action, that (as to any of (a) through
     (e) above) would constitute a distribution of the Rule 144A Securities
     under the Act, that would render the disposition of any Rule 144A
     Securities a violation of Section 5 of the Act or any state securities law,
     or that would require registration or qualification pursuant thereto.  We
     will not sell or otherwise transfer any of the Rule 144A Securities, except
     in compliance with the provisions Agreement.

     Securities to any Plan, or to any Person acting on behalf of or purchasing
     any such Rule 144A Securities with "plan assets" of any Plan, may not be

             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 prior to the Auction Date and distribute the questions and
             answers to 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.

     Re:  BankAmerica Manufactured Housing Contract Trust IV
          Senior/Subordinate Pass-Through Certificates, Series 1998-1

Ladies and Gentlemen:

          We are special tax counsel to Bank of America National Trust and
Savings Association ("BANTSA") and Bank of America, FSB ("BAFSB") (collectively
the "Registrants") in connection with the sale by the Registrants of the
securities described below (collectively, the "Certificates").  For purposes of
this opinion, capitalized terms used but not defined herein have the meanings
ascribed to them in the Agreement (as defined below).  The securities referred
to above are the following:

     1.   $734,260,000 (approximate) aggregate principal amount of 6.47%
          BankAmerica Manufactured Housing Contract Trust IV, Senior/Subordinate
          Pass-Through Certificates, Series 1998-1, Class A (the "Class A
          Certificates");

     2.   $67,158,000 (approximate) aggregate principal amount of BankAmerica
          Manufactured Housing Contract Trust IV, Senior/Subordinate Pass-
          Through Certificates, Series 1998-1, Class M (the "Class M
          Certificates"), the Pass-Through Rate on which is the lesser of (a)
          6.94% per annum and (b) the Weighted Average Net Contract Rate, in
          either case computed on the basis of a 360-day year of twelve 30-day
          months;

     3.   $53,727,000 (approximate) aggregate principal amount of BankAmerica
          Manufactured Housing Contract Trust IV, Senior/Subordinate Pass-

          Class M Certificates and the Class B-1 Certificates, the "Publicly
          Offered Certificates"), the Pass-Through Rate on which is the lesser
          of (a) 7.81% per annum and (b) the Weighted Average Net Contract Rate,

          day months;

     4.   $40,295,092.56 (approximate) aggregate principal amount of BankAmerica
          Manufactured Housing Contract Trust IV, Senior/Subordinate Pass-
          Through Certificates, Series 1998-1, Class B-2 (the "Class B-2
          Certificates"), the Pass-Through Rate on which is the lesser of (a)
          8.00% per annum and (b) the Weighted Average Net Contract Rate, in
          either case computed on the basis of a 360-day year of twelve 30-day
          months; and

     5.   BankAmerica Manufactured Housing Contract Trust IV, Senior/Subordinate
          Pass-Through Certificate, Series 1998-1, Class R (the "Class R
          Certificate"). The Class R Certificate will have no stated principal
          balance.

     The Certificates will be issued on the Closing Date pursuant to a Pooling
and Servicing Agreement dated as of March 1, 1998 (the "Agreement") among Bank
of America National Trust and Savings Association ("BANTSA"), BAFSB, acting
through its division, BankAmerica Housing Services ("BAFSB") (BAFSB and BANTSA
each individually a "Contract Seller" and collectively the "Contract Sellers,"
and BAFSB individually the "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 Registrants 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
Registrants, 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 March 16, 1998 and the Prospectus Supplement
dated March 24, 1998, 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 Registrants, 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 Registrants, 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.

INVESTORS MUST READ THIS PAGE BEFORE PROCEEDING TO THE TEXT.  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 NT&SA and BankAmerica Housing Services, an unincorporated
division of 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

particular trading strategy.  ANY SUCH OFFER TO BUY OR SELL ANY SECURITY WOULD
BE MADE PURSUANT TO A DEFINITIVE PROSPECTUS AND PROSPECTUS SUPPLEMENT PREPARED

representing interests in the above trust, and is based in part on information
provided by Bank of America NT&SA and BankAmerica Housing Services, an
unincorporated division of Bank of America, FSB, with respect to the expected
characteristics of the pool of manufactured housing contracts in which these

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

                                  (continued)

The defined terms used and not otherwise defined in the attached BankAmerica
Manufactured Housing Contract Trust IV, Series 1998-1 Computational Materials
for Classes A, M and B-1 Certificates of such Series 1998-1, 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%*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%*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).

"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.

                                  (continued)

"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 Class A , Class M
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.
