Dear Sirs:

     Green Tree Financial Corporation (the "Company") is a Minnesota corporation
with its principal place of business in Saint Paul, Minnesota.  The Company and
Green Tree Manufactured Housing Net Interest Margin Finance Corp. I ("Finance
I") (together, the "Registrants") have filed a Registration Statement relating
to the issuance and sale of $508,000,000 (approximate) principal amount of 6.90%
Securitized Net Interest Margin Certificates (the "Certificates") evidencing
interests in the Green Tree Securitized Net Interest Margin Trust 1994-A (the
"Trust").  The Certificates will be issued pursuant to a trust agreement (the
"Trust Agreement") dated as of January 1, 1994 among Finance I, a wholly owned
subsidiary of the Company, Green Tree Manufactured Housing Net Interest Margin
Finance Corp. II ("Finance II"), a wholly owned subsidiary of the Company, and
Wilmington Trust Company, a Delaware banking corporation, as Trustee.  The Trust
will issue $508,000,000 (approximate) aggregate principal amount of the
Certificates.  The assets of the Trust will consist of (i) the residual cashflow
from 26 real estate mortgage investment conduits ("REMICs"), whose assets
<PAGE>
 
consist of pools of manufactured housing contracts sold by or on behalf of the
Company to investors between 1987 and 1993, and (ii) a limited recourse note
(the "Finance I Note") issued by Finance I, and certain related property (as
described herein).  The Finance I Note will be secured by, and will be payable
solely from, (i) Guarantee Fees payable with respect to 15 pools of manufactured
housing contracts created by or on behalf of the Company between 1987 and 1993,
(ii) the excess servicing fees payable with respect to 28 such pools, and (iii)
certain excess spread payable with respect to manufactured housing contract GNMA
Certificates sold by the Company between 1978 and 1993, and certain related
property, all as described herein.  The Company, Finance I and Finance II will
be referred to collectively herein as the "Green Tree Parties".  The form of the
Trust Agreement has been incorporated by reference as an exhibit to the
Registration Statement (hereinafter defined).

     The Certificates are more fully described in a Registration Statement that
the Registrants have furnished to you.  Capitalized terms used but not defined
herein shall have the meanings given to them in the Finance I Note, the
Assignment Agreements, the Transfer Agreement, the Servicing Agreement, the
Security Agreement and the Trust Agreement (together, the "Trust Documents").
The term "you" as used herein, unless the context otherwise requires, shall mean
you and such persons as are named as co-managers in the Terms Agreement (defined
below).

     The offering of Certificates pursuant to this Agreement will be made
through you or through an underwriting syndicate managed by you.  When the
Company determines to make an offering of Certificates, it will enter into an
agreement (the "Terms Agreement") providing for the sale of such Certificates
to, and the purchase and offering thereof by, you and such other underwriters,
if any, selected by you as have authorized you to enter into such Terms
Agreement on their behalf (the "Underwriters", which term shall include you
whether acting alone in the sale of Certificates or as a member of an
underwriting syndicate).  The Terms Agreement relating to the offering of
Certificates shall specify, among other things, the price or prices at which the
Certificates are to be purchased by the Underwriters from the Trust and the
initial public offering price or prices or the method by which the price or
prices at which such Certificates are to be sold will be determined.  A Terms
Agreement, which shall be substantially in the form of Exhibit A hereto, may
take the form of an exchange of any standard form of written telecommunication
between you and the Company.  The offering of Certificates will be governed by
this Agreement, as supplemented by the Terms Agreement, and this Agreement and
such Terms Agreement shall inure to the benefit of and be binding upon

                                       2

the Underwriters participating in the offering of such Certificates.

     The Registrants have filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-1 (No. 33-51935) and two
related preliminary prospectuses for the registration of the Certificates under
the Securities Act of 1933 (the "1933 Act"), and have filed, and propose to
file, such amendments thereto as may have been required to the date hereof
pursuant to the 1933 Act and the rules of the Commission thereunder (the
"Regulations").  Such registration statement, as amended at the time when it
became effective under the 1933 Act, and the prospectus relating to the sale of
Certificates by the Company constituting a part thereof, as from time to time
each is amended or supplemented pursuant to the 1933 Act or otherwise, are
referred to herein as the "Registration Statement" and the "Prospectus",
respectively.

     The Company understands that you propose to make a public offering of the
Certificates as soon as you deem advisable after the Terms Agreement has been
executed and delivered.

     SECTION 1.  Representations and Warranties.  Each of the Green Tree Parties
                 ------------------------------                                 
represents and warrants to you as of the date hereof, and to the Underwriters
named in the Terms Agreement, all as of the date of such Terms Agreement (in
each case, the "Representation Date") as follows:

          (a)  The Registration Statement and the Prospectus, at the time the
     Registration Statement became effective did, and as of the Representation
     Date will, comply in all material respects with the requirements of the
     1933 Act and the Regulations.  The Registration Statement, at the time it
     became effective did not, and as of the Representation Date will not,
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading.  The Prospectus, as amended or
     supplemented at the time the Registration Statement became effective did
     not, and as amended or supplemented as of the Representation Date will not,
     contain any untrue statement of a material fact or omit to state a material
     fact necessary in order to make the statements therein, not misleading;
     provided, however, that the representations and warranties in this
     subsection shall not apply to statements in, or omissions from, the
     Registration Statement or Prospectus made in reliance upon and in
     conformity with information furnished to the Registrants in writing by you
     expressly for use in the Registration Statement or Prospectus.  The
     conditions to the use by the Registrants of a registration statement on

<PAGE>
 
     Form S-3 under the 1933 Act, as set forth in the General Instructions to
     Form S-3, have been satisfied with respect to the Registration Statement
     and the Prospectus.  There are no contracts or documents of any Green Tree
     Party which are required to be filed as exhibits to the Registration
     Statement pursuant to the 1933 Act or the Regulations which have not been
     so filed or incorporated by reference.

          (b)  Each of the Green Tree Parties has been duly incorporated and is
     validly existing as a corporation in good standing under the laws of the
     state of incorporation, with corporate power and authority to own, lease
     and operate its properties and conduct its business as described in the
     Prospectus and to enter into and perform its obligations under this
     Agreement, the Trust Documents and the Terms Agreement as such Green Tree
     Party may be a party to; and each of the Green Tree Parties is duly
     qualified as a foreign corporation to transact business and is in good
     standing in each jurisdiction in which the ownership or lease of its
     properties or the conduct of its business under the Trust Documents
     requires such qualification.

          (c)  Each of the Green Tree Parties is not in violation of its
     articles of incorporation, or certificate of incorporation, as applicable,
     or by-laws or in default in the performance or observance of any material
     obligation, agreement, covenant or condition contained in any contract,
     indenture, mortgage, loan agreement, note, lease or other instrument to
     which it is a party or by which it or its properties may be bound, which
     default might result in any material adverse change in the financial
     condition, earnings, affairs or business of any of the Green Tree Parties
     or which might materially and adversely affect the properties or assets
     thereof.

          (d)  The execution and delivery by the Green Tree Parties of this
     Agreement and the Terms Agreement and the execution and delivery of any
     Trust Document by a Green Tree Party are within the corporate power of the
     Company or the related Green Tree Party and have been duly authorized by
     all necessary corporate action on the part of the Company or the related
     Green Tree Party; and neither the issuance and sale of the Certificates to
     the Underwriters, nor the execution and delivery by the Company of this
     Agreement and the Terms Agreement, nor the execution and delivery of any
     Trust Document by a Green Tree Party, nor the consummation by any of the
     Green Tree Parties of any of the transactions therein contemplated, nor
     compliance by any of the Green Tree Parties with the provisions hereof or
     thereof, will materially conflict with or result in a material breach of,

                                       4
<PAGE>
 
     or constitute a material default under, any of the provisions of any law,
     governmental rule, regulation, judgment, decree or order binding on any of
     the Green Tree Parties or its properties or the articles of incorporation
     or certificate of incorporation, as applicable, or by-laws of any of the
     Green Tree Parties, or any of the provisions of any indenture, mortgage,
     contract or other instrument to which any Green Tree Party is a party or by
     which it is bound or result in the creation or imposition of any lien,
     charge or encumbrance upon any of its property pursuant to the terms of any
     such indenture, mortgage, contract or other instrument.

          (e)  This Agreement has been, and the Terms Agreement when executed
     and delivered as contemplated hereby and thereby will have been, duly
     authorized, executed and delivered by the Green Tree Parties, and each
     constitutes, or will constitute when so executed and delivered, a legal,
     valid and binding instrument enforceable against the Green Tree Parties in
     accordance with its terms, subject (i) to applicable bankruptcy,
     reorganization, insolvency, moratorium or other similar laws affecting
     creditors rights generally, (ii) as to enforceability, to general
     principles of equity (regardless of whether enforcement is sought in a
     proceeding in equity or at law) and (iii) as to enforceability with
     respect to rights of indemnity thereunder, to limitations of public policy
     under securities laws.

          (f)  The Trust Documents when executed and delivered as contemplated
     hereby and thereby will have been duly authorized, executed and delivered
     by each such Green Tree Party which is a party thereto, and will constitute
     when so executed and delivered, a legal, valid and binding instrument
     enforceable against any Green Tree Party which is a party thereto in
     accordance with its terms, subject (i) to applicable bankruptcy,
     reorganization, insolvency, moratorium or other similar laws affecting
     creditors' rights generally and (ii) as to enforceability, to general
     principles of equity (regardless of whether enforcement is sought in a
     proceeding in equity or at law).

          (g)  As of the Closing Time (as defined below), the Certificates will
     have been duly and validly authorized, and, when executed and authenticated
     as specified in the Trust Agreement, will be validly issued and outstanding
     and will be entitled to the benefits of the Trust Agreement, and will be

     Agreement.

     transactions contemplated by this Agreement, any of the Trust Documents or
     the Terms Agreement, except such as may be required under the 1933 Act, the

     business now operated by it and as described in the Prospectus and has
     received no notice of proceedings relating to the revocation or
     modification of any such license, certificate, authority or permit which,
     singly or in the aggregate, if the subject of an unfavorable decision,

     the Investment Company Act of 1940, as amended (the "1940 Act").

          (l)  The Certificates and the Trust Documents conform in all material

     transmit copies of the Prospectus to the Commission for filing pursuant to
     Rule 424 under the 1933 Act and will furnish to you as many copies of the
     Prospectus as you shall reasonably request.

          (b)  If at any time when the Prospectus is required by the 1933 Act to
     be delivered in connection with sales of the Certificates by you or the
     Underwriters, any event shall occur or condition exist as a result of which
     it is necessary, in the opinion of your counsel, counsel for the
     Registrants, or otherwise, to further amend or supplement the Prospectus in
     order that the Prospectus will not include an untrue statement of a
     material fact or omit to state any material fact necessary to make the
     statements therein, in the light of circumstances existing at the time it
     is delivered to a purchaser, not misleading or if it shall be necessary, in
     the opinion of any such counsel or otherwise,

                                       7

     at any such time to amend or supplement the Registration Statement or the
     Prospectus in order to comply with the requirements of the 1933 Act or the
     Regulations thereunder, the Registrants will promptly prepare and file with
     the Commission such amendment or supplement as may be necessary to correct
     such untrue statement or omission or to make the Registration Statement
     comply with such requirements, and within two business days will furnish to
     you as many copies of the Prospectus, as so amended or supplemented, as you
     shall reasonably request.

          (c)  The Registrants will give you reasonable notice of its intention
     to file any amendment to the Registration Statement or any amendment or
     supplement to the Prospectus, whether pursuant to the 1933 Act or otherwise

     1934, as amended (the "1934 Act")), will furnish you with copies of any
     such amendment or supplement or other documents proposed to be filed a
     reasonable time in advance of filing, and will not file any such amendment
     or supplement or other documents in a form to which you or your counsel
     shall object.

          (d)  The Registrants will notify you immediately, and confirm the
     notice in writing, (i) of the effectiveness of any amendment to the
     Registration Statement, (ii) of the mailing or the delivery to the
     Commission for filing of any supplement to the Prospectus or any document,
     other than reports to be filed pursuant to the 1934 Act, (iii) of the
     receipt of any comments from the Commission with respect to the
     Registration Statement or the Prospectus, (iv) of any request by the
     Commission for any amendment to the Registration Statement or any amendment
     or supplement to the Prospectus or for additional information, and (v) of
     the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement or suspension of the
     qualification of the Certificates or the initiation of any proceedings for
     that purpose.  The Registrants will make every reasonable effort to prevent
     the issuance of any such stop order and, if any such stop order is issued,
     to obtain the lifting thereof at the earliest possible moment.

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

          (f) The Registrants will endeavor, in cooperation with you, to qualify
     the Certificates for offering and sale under the applicable securities laws
     of such states and other jurisdictions of the United States as you may
     designate, and will maintain or cause to be maintained such qualifications
     in effect for as long as may be required for the distribution of the
     Certificates.  The Registrants will file or cause the filing of such
     statements and reports as may be required by the laws of each jurisdiction
     in which the Certificates have been qualified as above provided.

     SECTION 4.  Conditions of Underwriter's Obligations.  The obligations of
                 ---------------------------------------                     
the Underwriters to purchase Certificates pursuant to the Terms Agreement are
subject to the accuracy of the representations and warranties on the part of the
Green Tree Parties herein contained, to the accuracy of the statements of the
Green Tree Parties' officers made pursuant hereto, to the performance by the
Green Tree Parties of all of its obligations hereunder and to the following
further conditions:

          (a)  At the Closing Time (i) no stop order suspending the
     effectiveness of the Registration Statement shall have been issued or
     proceedings therefor initiated or threatened by the Commission, (ii) the
     Certificates shall have received the rating specified in the Terms
     Agreement, and (iii) there shall not have come to your attention any facts
     that would cause you to believe that the Prospectus, at the time it was
     required to be delivered to a purchaser of the Certificates, contained an
     untrue statement of a material fact or omitted to state a material fact
     necessary in order to make the statements therein, in light of the
     circumstances existing at such time, not misleading.

          (b)  At or prior to the Closing Time you shall have received:

               (1)  The favorable opinion, dated as of the Closing Time, of
          Dorsey & Whitney, special counsel and general counsel for the Green
          Tree Parties (the "Underwriter Opinion"), substantially in the form
          attached hereto as Exhibit B.

     Such counsel shall state that it has participated in the conferences with
officers and other representatives of the Registrants, your counsel,
representatives of the independent accountants for the Registrants and you at
which the contents of the Registration Statement and the Prospectus were
discussed and, although such counsel is not passing upon and does not assume
responsibility for, the factual accuracy, completeness or fairness of the
statements contained in the Registration Statement or

                                       9
<PAGE>
 
the Prospectus (except as stated in paragraphs (10) and (12) of the Underwriter
Opinion) and has made no independent check or verification thereof for the
purpose of rendering this opinion, on the basis of the foregoing (relying as to
materiality to a large extent upon the certificates of officers and other
representatives of the Registrants), nothing has come to their attention that
leads such counsel to believe that the Registration Statement, when it became
effective, contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Registration Statement and the
Prospectus on the date of the Terms Agreement contained, and the Prospectus on
the date hereof contains, any untrue statement of a material fact or omitted or
omits to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, except that such counsel need express no view with respect to the
financial statements, schedules and other financial, statistical and numerical
data included in or incorporated by reference into the Registration Statement or
the Prospectus.

     Said counsel may state that they are admitted to practice only in the State
of Minnesota, that they are not admitted to the Bar in any other State and are
not experts in the law of any other State and to the extent that the foregoing
opinions concern the laws of any other State such counsel may rely upon the
opinion of counsel satisfactory to you and admitted to practice in such
jurisdiction.  Any opinions relied upon by such counsel as aforesaid shall be
addressed to you and shall be delivered together with the opinion of such
counsel, which shall state that such counsel believes that their reliance
thereon is justified.

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

               (i)  The Trust Agreement has been duly authorized, executed and
          delivered by the Trustee and is enforceable against the Trustee in
          accordance with its terms, subject to customary and usual exceptions.

              (ii)  The Trustee has full power and authority to execute and
          deliver the Trust Agreement and to perform its obligations thereunder.

             (iii)  To the best of such counsel's knowledge, there are no
          actions, proceedings or investigations pending or threatened against
          or affecting the Trustee before or by any court, arbitrator,
          administrative

                                       10
<PAGE>
 
          agency or other governmental authority which, if adversely decided,
          would materially and adversely affect the ability of the Trustee to
          carry out the transactions contemplated in the Trust Agreement.

              (iv)  No consent, approval or authorization of, or registration,
          declaration or filing with, any court or governmental agency or body
          of the jurisdiction of incorporation of the Trustee is required for
          the execution, delivery or performance by the Trustee of the Trust
          Agreement.

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

          (3)  The favorable opinion or opinions, dated as of the Closing Time,
     of counsel for the Underwriters with respect to the issue and sale of the
     Certificates, the Registration Statement, this Agreement, the Prospectus
     and other related matters as you may require.

     (c)  At the Closing Time you shall have received a certificate of the
President or a Vice President of each of the Green Tree Parties, dated as of
such Closing Time, to the effect that the representations and warranties of each
of the Green Tree Parties contained in Section 1 are true and correct with the
same force and effect as though such Closing Time were the Representation Date.

     (d)  You shall have received from KPMG Peat Marwick, or other independent
certified public accountants acceptable to you, a letter, dated as of the Terms
Agreement, or as soon thereafter as is practicable, and as of the Closing Time,
delivered at such times, in the form heretofore agreed to.

     (e)  At the Closing Time you shall have received, addressed to you, any
additional opinions delivered by counsel pursuant to the request of the Rating
Agencies rating the Certificates.

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

                                       11
<PAGE>
 
contemplated shall be satisfactory in form and substance to you and counsel for
the Underwriters.

     (g)  As of the Closing Time, each of the Trust Documents will have been
duly authorized, executed and delivered by, and will constitute a legal, valid
and binding obligation of, and will be enforceable against each of the Green
Tree Parties which is a party thereto, in accordance with its terms, subject to
applicable bankruptcy, reorganization, insolvency, moratorium or other similar
laws affecting creditors' rights generally and as to enforceability, to general
principles of equity (regardless whether enforcement is sought in a proceeding
in equity or at law).

     (h)  At the Closing Time, Moody's Investors Service, Inc. will have
delivered to the Company a letter stating that the Certificates are rated "Baa3"
and Fitch Investor Service, Inc. will have delivered a letter to the Company
stating that the Certificates are rated "BBB+".

     If any condition specified in this Section shall not have been fulfilled
when and as required to be fulfilled, the Terms Agreement may be terminated by
you by notice to the Company at any time at or prior to the Closing Time, and
such termination shall be without liability of any party to any other party
except as provided in Section 5.

     SECTION 5.  Payment of Expenses.  The Company will pay all expenses
                 -------------------                                    
incident to the performance of its obligations under this Agreement, including

<PAGE>
 
reasonably request, of copies of the Pooling and Servicing Agreement, (viii) the

provisions of Section 4 or Section 9(i) hereof, the Company shall reimburse you

     SECTION 6.  Indemnification.  (a)  The Company agrees to indemnify and hold
                 ---------------                                                
harmless you and each person, if any, who controls you within the meaning of
Section 15 of the 1933 Act as follows:

          (i)  against any and all loss, liability, claim, damage and expense
whatsoever arising out of any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement (or any amendment
thereto), or the omission or alleged omission therefrom of a material fact
required to be stated therein or necessary to make the statements therein not
misleading or arising out of any untrue statement or alleged untrue statement of
a material fact contained in the Prospectus (or any amendment or supplement
thereto) or the omission or alleged omission therefrom of a material fact
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, unless such untrue statement or
omission or alleged untrue statement or omission was made in reliance upon and
in conformity with written information furnished to either of the Registrants by
the Underwriters expressly for use in the Registration Statement (or any
amendment thereto) or the Prospectus (or any amendment or supplement thereto);

         (ii)  against any and all loss, liability, claim, damage and expense
whatsoever to the extent of the aggregate amount paid in settlement of any
litigation, or investigation or proceeding by any governmental agency or body,
commenced or threatened, or of any claim whatsoever based upon any such untrue
statement or omission, (A) if such settlement is effected with the written
consent of the Company or (B) if such settlement is effected without the written
consent of the Company more than 30 days after receipt by the Company of a
notice from the Underwriters, substantially reflecting the proposed terms of
such settlement,

                                       13
<PAGE>
 
to which the Company has not responded prior to the date such settlement is
effected; and

        (iii)  against any and all expense whatsoever (including the fees and
disbursements of counsel chosen by you), reasonably incurred in investigating,
preparing to defend or defending against any litigation, or investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue statement or omission, to the extent
that any such expense is not paid under (i) or (ii) above, which expenses shall
be reimbursed as they are incurred.

     This indemnity agreement will be in addition to any liability which either
of the Registrants may otherwise have.  Insofar as this indemnity may permit
indemnification for liabilities under the 1933 Act of any person who is a
partner of the Underwriters entitled to indemnity hereby or who controls the
Underwriters within the meaning of Section 15 of the 1933 Act and who, at the
date of this Agreement is a director, officer or controlling person of either of
the Registrants, such indemnity agreement is subject to the undertaking of
either of the Registrants in the Registration Statement.

     (b)  Each Underwriter severally agrees to indemnify and hold harmless each
of the Registrants, each of the Registrants' directors, each of the
Registrants's officers who signed the Registration Statement, and each person,
if any, who controls either of the Registrants within the meaning of Section 15
of the 1933 Act against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a) of this Section, but only
with respect to untrue statements or omissions or alleged untrue statements or
omissions, made in the Registration Statement (or any amendment thereto) or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to either of the Registrants by
you expressly for use in the Registration Statement (or any amendment thereto)
or the Prospectus (or any amendment or supplement thereto).  This indemnity
agreement will be in addition to any liability that such Underwriter may
otherwise have.

     (c)  Each indemnified party shall give prompt notice to each indemnifying
party of any action commenced against it with respect to which indemnity may be
sought hereunder but failure to so notify an indemnifying party shall not
relieve it from any liability that it may have otherwise than on account of this
indemnity agreement.  An indemnifying party may participate at its own expense
in the defense of such action.  In no event shall the indemnifying parties be
liable for the fees and expenses of

                                       14
<PAGE>
 
more than one counsel (in addition to local counsel) for all indemnified parties
in connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances.

     SECTION 7.  Contribution.  In order to provide for just and equitable
                 ------------                                             
contribution in circumstances in which the indemnity agreement provided for in
Section 6 hereof is for any reason held to be unenforceable by the indemnified
parties although applicable in accordance with its terms, the Company on the one
hand, and the Underwriters, on the other, shall contribute to the aggregate
losses, liabilities, claims, damages and expenses of the nature contemplated by
said indemnity agreement incurred by the Company and one or more of the
Underwriters (i) in such proportion as shall be appropriate to reflect the
relative benefit received by the Underwriters, as represented by the percentage
that the Underwriting discount or discounts on the cover of such Prospectus
bears to the initial public offering price or prices as set forth thereon, and
the Company shall be responsible for the balance; 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 benefit referred to in
clause (i) above but also the relative fault of the Company on the one hand and
the Underwriters on the other with respect to statements or omissions which
resulted in such loss, claim, damage or liability, or action in respect thereof,
as well as any other relevant equitable considerations; provided, however, that
no person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation and, provided further, no
                                                     -------- -------    
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price of the Certificates purchased by such Underwriter
pursuant to the Terms Agreement exceeds the amount of any damages which such
Underwriter has otherwise paid or become liable to pay by reason of any untrue
or alleged untrue statement or omission or alleged omission.  For purposes of
this Section, each person, if any, who controls the Underwriters within the
meaning of Section 15 of the 1933 Act shall have the same rights to contribution
as the Underwriters and each director of the Company, each officer of either of
the Registrants who signed the Registration Statement, and each person, if any,
who controls either of the Registrants within the meaning of Section 15 of the
1933 Act shall have the same rights to contribution as each of the Registrants.

     SECTION 8.  Representations, Warranties and Agreements to survive Delivery.
                 --------------------------------------------------------------
All representations, warranties and agreements contained in this Agreement, or
contained in certificates of Officers of any of the Green Tree Parties submitted
pursuant

                                       15
<PAGE>
 
hereto, shall remain operative and in full force and effect, regardless of any
termination of this Agreement, or any investigation made by or on behalf of the
Underwriters or controlling person thereof, or by or on behalf of any of the
Green Tree Parties and shall survive delivery of any Certificates to the
Underwriters.

     SECTION 9.  Termination of Agreement.  This Agreement may be terminated for
                 ------------------------                                       
any reason at any time by either the Company or you upon the giving of thirty
days' written notice of such termination to the other party hereto.  You, as
Representative of the Underwriters named in the Terms Agreement, may also
terminate the Terms Agreement, immediately upon notice to the Company, at any
time at or prior to the Closing Time (i) if there has been, since the date of
such Terms Agreement or since the respective dates as of which information is
given in the Registration Statement or Prospectus any change, or any development
involving a prospective change in, or affecting, the condition, financial or
otherwise, earnings, affairs or business of the Company whether or not arising
in the ordinary course of business, which in your judgment would materially
impair the market for, or the investment quality of, the Certificates, or (ii)
if there has occurred any outbreak of hostilities or other calamity or crisis
the effect of which on the financial markets of the United States is such as to
make it, in your judgment, impracticable to market the Certificates or enforce
contracts for the sale of the Certificates, or (iii) if trading generally on
either the New York Stock Exchange or the American Stock Exchange has been
suspended, or minimum or maximum prices for securities have been required, by
either of said exchanges or by order of the Commission or any other governmental
authority, or if a banking moratorium has been declared by either Federal,
Minnesota or New York authorities.  In the event of any such termination, (A)
the covenants set forth in Section 3 with respect to any offering of
Certificates shall remain in effect so long as the Underwriters own any such
Certificates purchased from the Company pursuant to the Terms Agreement and (B)
the covenant set forth in Section 3(c), the provisions of Section 5, the
indemnity agreement set forth in Section 6, and the contribution provisions set
forth in Section 7, and the provisions of Sections 8 and 13 shall remain in
effect.

     SECTION 10.  Default by One or More of the Underwriters.  If one or more of
                  ------------------------------------------                    
the Underwriters participating in an offering of Certificates shall fail at the
Closing Time to purchase the Certificates which it or they are obligated to
purchase hereunder and under the Terms Agreement (the "Defaulted Certificates"),
then such of you as are named therein shall have the right, within 24 hours
thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to

                                       16
<PAGE>
 
purchase all, but not less than all, of the Defaulted Certificates in such
amounts as may be agreed upon and upon the terms herein set forth.  If, however,
you have not completed such arrangements within such 24-hour period, then:

          (1)  if the aggregate principal amount of Defaulted Certificates does
     not exceed 10% of the aggregate principal amount of the Certificates to be
     purchased pursuant to such Terms Agreement, the non-defaulting Underwriters
     named in such Terms Agreement shall be obligated to purchase the full
     amount thereof in the proportions that their respective underwriting
     obligations hereunder bear to the underwriting obligations of all such 
     non-defaulting Underwriters, or

          (2)  if the aggregate principal amount of Defaulted Certificates
     exceeds 10% of the aggregate principal amount of the Certificates to be
     purchased pursuant to such Terms Agreement, the Terms Agreement shall
     terminate, without any liability on the part of any non-defaulting
     Underwriters.

     No action taken pursuant to this Section shall relieve any defaulting
Underwriters from liability with respect to any default of such Underwriters
under this Agreement and the Terms Agreement.

     In the event of a default by any Underwriters as set forth in this Section,
either you or the Company shall have the right to postpone the Closing Time for
a period of time not exceeding seven days in order that any required changes in
the Registration Statement or Prospectus or in any other documents or
arrangements may be effected.

     SECTION 11.  Notices.  All notices and other communications hereunder shall
                  -------

     SECTION 12.  Parties.  This Agreement shall inure to the benefit of and be
                  -------                                                      
binding upon you and each of the Green Tree Parties and any Terms Agreement
shall inure to the benefit of and be binding upon each of the Green Tree Parties
and any Underwriter who becomes a party to a Terms Agreement, and their
respective successors.  Nothing expressed or mentioned in this Agreement or a
Terms Agreement is intended or shall be construed

                                       17
<PAGE>
 
to give any person, firm or corporation, other than the parties hereto or
thereto and their respective successors and the controlling persons and officers
and directors referred to in Sections 6 and 7 and their heirs and legal
representatives any legal or equitable right, remedy or claim under or with
respect to this Agreement or the Terms Agreement or any provision herein or
therein contained.  This Agreement and the Terms Agreement and all conditions
and provisions hereof or thereof are intended to be for the sole and exclusive
benefit of the parties and their respective successors and said controlling
persons and officers and directors and their heirs and legal representatives (to
the extent of their rights as specified herein and therein) and for the benefit
of no other person, firm or corporation.  No purchaser of Certificates from any

income, gain, loss, deduction and credit, if any, entering into the computation
thereof) shall be allocated:

     (a)  to the Subordinated Certificateholders in equal proportions; and

     (b)  in the event the Senior Certificateholders are deemed to be partners
of the partnership created hereby, among such Senior Certificateholders as of
the first Record Date following the end of such month in proportion to their
ownership of the principal amount of Senior Certificates on such date, in an
amount of such income up to the sum of the Senior Certificateholders' Interest
Distributable Amount for such month, and the balance thereof shall be allocated
to the Subordinated Certificateholders in accordance with clause (a) above.  If
the net income in succeeding months of the Trust for any month is insufficient
for the allocations to Senior Certificateholders described in this clause (b),
if applicable, net income shall first be allocated to such Senior
Certificateholders to make up such

income tax purposes (and each item of income, gain, loss and deduction entering
into the computation thereof) shall be allocated to the Subordinated
Certificateholders to the extent the Subordinated Certificateholders are
reasonably expected to bear the economic burden of such net losses, then net
losses shall be allocated among the Senior Certificateholders as of the first
Record Date following the end of such month in proportion to their ownership of
principal amount of Senior Certificates on such Record Date.  Notwithstanding
anything in this Agreement to the contrary, the Subordinated Certificateholders
shall be allocated an aggregate of at least 1% of each item of income, profit,
gain or loss of the Trust.  The Subordinated Certificateholders are authorized
to modify the allocations in this paragraph if necessary or appropriate, in
their sole discretion, for the allocations to fairly reflect the economic
income, gain or loss to the Subordinated Certificateholders or the Senior
Certificateholders, or to comply with the provisions of the Code and the
accompanying Treasury Regulations.

hereby initially appointed Certificate Registrar for the purpose of registering
Certificates and transfers and exchanges of Certificates as provided in this
Agreement.

     (b)  Upon surrender for registration of transfer of any Certificate at the
office or agency maintained pursuant to Section 3.10, the Trustee shall execute,
authenticate and deliver (or shall cause the Authentication Agent to
authenticate and deliver), in the name of the designated transferee or
transferees, one or more new Certificates in authorized denominations of a like
class and aggregate principal amount, or Percentage Interest, with respect to

of a like aggregate principal amount upon surrender of the Certificates to be
exchanged at the office or agency maintained pursuant to Section 3.10.

     (c)  All Certificates issued upon any registration of transfer or exchange

registration of transfer or exchange.

     (d)  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 and the Certificate Registrar duly executed by
the Holder or his attorney duly authorized in writing.  Each Certificate

may be imposed in connection with any transfer or exchange of Certificates.

     (f)  Except as provided in paragraph (g) and (i) below, the Book-Entry
Certificates shall at all times remain registered in the name of the Depository

depository designated pursuant to paragraph (g) below; (ii) the Depository shall
maintain book-entry records with respect to the Certificate Owners and with
respect to ownership and transfers of such Senior Certificates; (iii) ownership

representatives of the Certificate Owners for purposes of

                                    -18-
<PAGE>
 
exercising the rights of Holders under this Agreement (and requests and
directions for and votes of such representatives shall not be deemed to be
inconsistent if they are made with respect to different Certificate Owners); and
(vi) the Trustee may rely and shall be fully protected in relying upon
information furnished by the Depository with respect to its Depository
Participants and furnished by the Depository Participants with respect to
indirect participating firms and persons shown on the books of such indirect
participating firms as direct or indirect Certificate Owners.

     (g)  If the Depository advises the Trustee in writing that the Depository
is no longer willing or able properly to discharge its duties as Depository, the
Trustee shall so notify the Depository and demand the return of all Senior
Certificates held by the Depository.  The Certificate Registrar shall thereupon
register the transfer of such Senior Certificates to a successor Depository
named by the Depositor and acceptable to the Depositor and the Trustee.

     (h)  If,

     (1)  (i) the Administrator, the Depositor or the Depository advises the
   Trustee in writing that the Depository is no longer willing or able
   properly to discharge its responsibilities as Depository, and (ii) the
   Administrator or the Depositor is unable to locate a qualified successor,

     (2)  the Depositor at its sole option advises the Trustee in writing that
   it elects to terminate the book-entry system through the Depository, or

     (3)  an Event of  Default shall have occurred and be continuing, and
   Certificate Owners having a beneficial interest in the Senior Certificates
   at least equal to a Certificate Majority advise the Trustee through the
   Depository that the continuation of a book-entry system is no longer in the
   best interests of the Certificate Owners,

the Trustee shall notify all Certificate Owners, through the Depository, of the
occurrence of any such event and of the availability of definitive, fully
registered Senior Certificates (the "Definitive Certificates") to Certificate
Owners requesting the same.  Upon surrender to the Trustee of the Senior
Certificates by the Depository, accompanied by registration instructions from
the Depository for registration or transfer, the Trustee shall issue the
Definitive Certificates in accordance with such instructions.  Neither the
Certificate Registrar nor the Trustee shall be liable for any delay in delivery
of such instructions and may conclusively rely on, and shall be protected in
relying on, such instructions.  Finance I shall pay all expenses incurred in
connection with the notification of Certificate Owners and the issuance of
Definitive Certificates hereunder.  Upon the issuance of Definitive Certificates
the Trustee shall recognize the Holders of the Definitive Certificates as
Certificateholders hereunder.

Senior Certificates evidencing $150,000,000 of principal amount each, and the
fourth such Senior Certificate evidencing $58,000,000 of original principal

of the aggregate principal amount of the Senior Certificates as of the Cut-off

nominee shall bear the following legend:

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

     (j)  On the Closing Date, Finance I and Finance II shall receive for
adequate consideration and thereafter shall have beneficial and record ownership
of the Subordinated Certificates, which Subordinated Certificates shall be
issued in definitive form.

     (k)  The Certificates may not be acquired by a "disqualified organization"
(as defined below).  By acceptance of a Certificate, the Holder thereof shall be
deemed to have represented and warranted that it is not a disqualified
organization.  Any attempted or purported transfer in violation of these
transfer restrictions will be null and void and will vest no rights in any
purported transferee.  A "disqualified organization" means (i) the United
States, any State or political subdivision thereof, any foreign government, any
international organization, or any agency or instrumentality of the foregoing
(not including instrumentalities described in Section 168(h)(2)(D) of the Code
or the Federal Home Loan Mortgage Corporation), (ii) any organization (other
than a cooperative described in Section 521 of the Code) that is exempt from

the Code or (iii) any organization described in Section 1381(a)(2)(C) of the
Code.

                   -------------------------------------------------         
any mutilated Certificate is surrendered to the Certificate Registrar, or the
Certificate Registrar receives evidence to its satisfaction of the destruction,
loss or theft of any Certificate, and (b) there is delivered to the Certificate
Registrar and the Trustee such security or indemnity as may be required by them
to save each of them harmless, then, in the absence of notice to the Certificate
Registrar or the Trustee that such

                                    -20-
<PAGE>
 
Certificate has been acquired by a bona fide purchaser, the Trustee on behalf of
the Trust shall execute, authenticate and deliver (or the Authentication Agent
shall authenticate and deliver), in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate of like
tenor and portion of the aggregate principal balance of the Certificates.  In
connection with the issuance of any new Certificate under this Section 3.7, 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 and the Certificate
Registrar) connected therewith.  Any duplicate Certificate issued pursuant to
this Section 3.7 shall constitute conclusive evidence of ownership, as if
originally issued, whether or not the lost, stolen or destroyed Certificate
shall be found at any time.

     Section 3.8.  Persons Deemed Certificate Owners.  Prior to due presentation
                   ---------------------------------                            
of a Certificate for registration of transfer, the Trustee or the Certificate
Registrar and any agent of the Trustee or the Certificate Registrar may treat
the person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions pursuant to Section 5.2
and for all other purposes whatsoever, and neither the Trustee nor the
Certificate Registrar nor any agent of the Trustee nor the Certificate Registrar
shall be affected by any notice to the contrary.

     Section 3.9.  Access to List of Certificateholders' Names and Addresses.
                   ---------------------------------------------------------  
The Trustee shall furnish or cause to be furnished to the Depositor within 15
days after receipt by the Trustee of a written request therefor from such party,
a list, in such form as such party may reasonably require, of the names and
addresses of the Senior Certificateholders as of the most recent Record Date for
payment of distributions to Senior Certificateholders.  If Definitive
Certificates have been issued and three or more Senior Certificateholders, or
one or more Senior Certificateholders evidencing not less than 25% of the
aggregate principal balance of the Senior Certificates (hereinafter referred to
as "Applicants"), apply in writing to the Trustee, and such application states
that the Applicants desire to communicate with other Senior Certificateholders
with respect to their rights under this Agreement or under the Senior
Certificates and is accompanied by a copy of the communication that such
Applicants propose to transmit, then the Trustee shall, within five Business
Days after the receipt of such application, afford such Applicants access,
during normal business hours, to the current list of Senior Certificateholders.
Every Senior Certificateholder, by receiving and holding a Senior Certificate,
agrees that neither the Depositor nor the Trustee, nor any agent thereof, shall
be held accountable by reason of the disclosure of any such information as to
the names and addresses of the Senior Certificateholders under this Agreement,
regardless of the source from which such information was derived.

     Section 3.10.  Maintenance of Office or Agency.  The Trustee shall maintain
                    -------------------------------

registration of transfer or exchange and where notices and demands to or upon
the Trustee in respect of the Certificates and the Related Documents may be
served.  The Trustee initially designates First Trust National Association, 180
East Fifth Street, St. Paul, Minnesota  55101, as its principal agency for such
purposes.  The Trustee shall give prompt written notice to the Depositor and to
the Certificateholders of any change in the location of the Certificate Register
or any such office of agency.

     Section 3.11.  Appointment of Paying Agent.  The Paying Agent shall make
                    ---------------------------                              
distributions to Certificateholders from the Certificate Account pursuant to
Section 5.2 and shall report the amounts of such distributions to the Trustee.
Any Paying Agent shall have the revocable power to withdraw funds from the
Certificate Account for the purpose of making the distributions referred to
above.  The Trustee may revoke such power and remove the Paying Agent if the
Trustee determines in its sole discretion that the Paying Agent shall have
failed to perform its obligations under this Agreement in any material respect.
The Paying Agent shall initially be First Trust National Association, with an
office at 180 East 5th Street, St. Paul, Minnesota  55101, Attention:  Corporate
Trust Operations, Second Floor.  First Trust National Association shall be
permitted to resign as Paying Agent upon 30 days' written notice to the Trustee.
In the event that First Trust National Association shall no longer be the Paying
Agent, the Trustee shall appoint a successor to act as Paying Agent (which shall
be a bank or trust company).  The Trustee shall cause such successor Paying
Agent or any additional Paying Agent appointed by the Trustee to execute and
deliver to the Trustee an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Trustee that as Paying Agent, such
successor Paying Agent or additional Paying Agent will hold all sums, if any,
held by it for payment to the Certificateholders in trust for the benefit of the
Certificateholders entitled thereto until such sums shall be paid to such
Certificateholders.  The Paying Agent shall return all unclaimed funds to the
Trustee and upon removal of a Paying Agent such Paying Agent shall also return
all funds in its possession to the Trustee.  The provisions of Sections 7.1,
7.3, 7.4 and 8.1 shall apply to the Trustee also in its role as Paying Agent,
for so long as the Trustee shall act as Paying Agent and, to the extent
applicable, to any other paying agent appointed hereunder.  Any reference in
this Agreement to the Paying Agent shall include any co-paying agent unless the
context requires otherwise.

     Section 5.1.  Certificate Account.
                   ------------------- 

     (a)  The Trustee, for the benefit of the Certificateholders, shall
establish and maintain the Certificate Account in the name of the Trust for the
benefit of the Certificateholders.  The Certificate Account shall be an Eligible
Account and initially shall be a segregated Certificate Account established by
the Administrator at First Bank National Association; provided, however, that
                                                      --------  -------      
the Trustee and the Administrator hereby agree to establish the Certificate
Account at the same Eligible Institution where the certificate accounts with
respect to the Securitized Pools and the custodial account with respect to the
GNMA Pools are currently established; and provided, further, if the certificate
                                          --------  -------                    
accounts with respect to the Securitized Pools are transferred to another
Eligible Institution, the Trustee and the Administrator hereby agree to transfer
the Certificate Account to the same Eligible Institution.

                                    -23-
<PAGE>
 
     (b)  The Trustee shall possess all right, title and interest in all funds
on deposit from time to time in the Certificate Account and in all proceeds
thereof.  If, at any time, the Certificate Account ceases to be an Eligible
Account, the Trustee shall within five Business Days (or such longer period, not
to exceed 30 calendar days, as to which each Rating Agency may consent)
establish a new Certificate Account as an Eligible Account and shall transfer
any cash and/or any investments to such new Certificate Account.

     (c)  All amounts held in the Certificate Account shall, to the extent
permitted by applicable laws, rules and regulations, be invested, by the
Trustee, in Eligible Investments that mature not later than one Business Day
prior to the Distribution Date to which such amounts relate.  Investments in
Eligible Investments shall be made in the name of the Trust, and such
investments shall not be sold or disposed of prior to their maturity.  Any
investment of funds in the Certificate Account shall be made in Eligible
Investments held by a financial institution with respect to which (a) such
institution has noted the Trustee's interest therein by book entry or otherwise
and (b) a confirmation of the Trustee's interest has been sent to the Trustee by
such institution, provided that such Eligible Investments are (i) specific
certificated securities, and (ii) either (A) in the possession of such
institution or (B) in the possession of a clearing corporation in New York or
Delaware, registered in the name of such clearing corporation, not endorsed for
collection or surrender or any other purpose not involving transfer, not
containing any evidence of a right or interest inconsistent with the Trustee's
security interest therein, and held by such clearing corporation in an account
of such institution.  Subject to the other provisions hereof, the Trustee shall
have sole control over each such investment and the income thereon, and any
certificate or other instrument evidencing any such investment, if any, shall be
delivered directly to the Trustee or its agent, together with each document of
transfer, if any, necessary to transfer title to such investment to the Trustee
in a manner which complies with this Section 5.1.  All interest, dividends,
gains upon sale and other income from, or earnings on investment of funds in the
Certificate Account shall be distributed on the next Distribution Date pursuant
to Section 5.2.  The Subordinated Certificateholders shall deposit in the
Certificate Account an amount equal to any net loss on such investments
immediately as realized.

     Section 5.2.  Distribution of Funds in Certificate Account.
                   -------------------------------------------- 

     (a)  On each Distribution Date, other the Distribution Date occurring in
March 1994, the Trustee will, based on the information contained in the Monthly
Report delivered on the related Determination Date pursuant to Section 1.01 of
the Servicing Agreement, cause to be distributed all funds in the Certificate
Account to Certificateholders, to the extent of the Amount Available, in the
order of priority set forth below.  With respect to the Distribution Date
occurring in March 1994, the Trustee will cause to be distributed to the
Subordinated Certificateholders, on the Closing Date, an amount equal to the
amount of interest that would have accrued on the original principal amount of
the Certificates at the Interest Rate from

                                    -24-
<PAGE>
 
January 15, 1994 to the Closing Date, and on March 25, 1994, the Trustee will
cause to be distributed to the Senior Certificateholders all funds in the
Certificate Account, to the extent of the Amount Available, in the order of
priority set forth below.  After the Distribution Date occurring in March 1994,
no amounts deposited in the Certificate Account shall be allocable or paid to
the Subordinated Certificateholders until the Senior Certificates have been paid
in full.

            (i)   first, from the Amount Available, to the Senior Certificate-
     holders, on a pro rata basis, an amount equal to the Senior Certificate-
     holders' Interest Distributable Amount; provided, however, that if the 
                                             --------  -------
     Amount Available and the amount withdrawn from the Reserve Fund pursuant
     to Section 5.7 is insufficient to pay the full amount of the Senior
     Certificateholders' Interest Distributable Amount, any amounts so
     distributed on such Distribution Date will be deemed applied first to any
     accrued but unpaid interest from prior Distribution Dates (and applied to
     unpaid interest from the earliest Distribution Date first), and next to
     the interest accrued for such Distribution Date;

            (ii)  second, to the Trustee, an amount equal to the expenses and 
     fees of the Trustee for such period (to the extent not paid by Green Tree
     or the Subordinated Certificateholders) pursuant to Section 8.1;

            (iii) third, to the Administrator, an amount equal to the expenses
     and fees of the Administrator for such period (to the extent not paid by
     Green Tree or the Subordinated Certificateholders) pursuant to Section
     8.1;

            (iv)  fourth, to the Senior Certificateholders, on a pro rata 
     basis, an amount equal to the Senior Certificateholders' Principal
     Distributable Amount; and

            (v)   fifth, following payment in full of the Senior Certificates,
     to the Subordinated Certificateholders according to their respective
     Percentage Interests.

            (b)   On the Distribution Date following the date on which the
Subordinated Certificateholders have exercised their option to cause the Trust
to prepay the Senior Certificates pursuant to Section 5.6 hereof, the Trustee
will distribute all amounts on deposit in the Certificate Account as follows,
taking into account any concurrent distribution made pursuant to Section
5.2(a):

            (i)   first, to the Senior Certificateholders, on a pro rata basis,
     an amount equal to the Senior Certificateholders' Interest Distributable 
     Amount;

            (ii)  second, to the Trustee, an amount equal to the expenses and 
     fees of the Trustee for such period (to the extent not paid by Green Tree
     or the Subordinated Certificateholders) pursuant to Section 8.1;

                                    -25-
<PAGE>
 
            (iii) third, to the Administrator, an amount equal to the expenses
     and fees of the Administrator for such period (to the extent not paid by
     Green Tree or the Subordinated Certificateholders) pursuant to Section
     8.1;

            (iv)  fourth, to the Senior Certificateholders, on a pro rata 
     basis, the outstanding principal balance on the Senior Certificates; and

            (v)   fifth, to the Subordinated Certificateholders, according to 
     their respective Percentage Interests.

            (c)   On the Distribution Date on which Insolvency Proceeds (as
defined herein) are deposited in the Certificate Account pursuant to Section
10.2 (or on the Distribution Date immediately following such deposit if such
proceeds are not deposited in the Certificate Account on a Distribution Date),
the Trustee will distribute the Insolvency Proceeds so deposited in the
Certificate Account, taking into account any concurrent distribution made
pursuant to Section 5.2(a) or 5.2(b):

            (i)   first, to the Senior Certificateholders, on a pro rata basis,
     an amount equal to the Senior Certificateholders' Interest Distributable 
     Amount;

            (ii)  second, to the Trustee, an amount equal to the expenses and 
     fees of the Trustee for such period (to the extent not paid by Green Tree
     or the Subordinated Certificateholders pursuant to Section 8.1;

            (iii)  third, to the Administrator, an amount equal to the 
     expenses and fees of the Administrator for such period (to the extent not
     paid by Green Tree or the Subordinated Certificateholders) pursuant to
     Section 8.1;

            (iv)  fourth, to the Senior Certificateholders, on a pro rata 
     basis, the outstanding principal balance on the Senior Certificates; and

            (v)   fifth, to the Subordinated Certificateholders, according to 
     their Percentage Interests.

            (d)   On each Distribution Date, the Trustee shall forward or
cause to be forwarded by mail to each holder of a Senior Certificate and (if
Green Tree is not the Servicer) Green Tree, the Monthly Report prepared by the
Servicer pursuant to the Servicing Agreement, attached hereto as Exhibit H.

            The Trustee and the Servicer shall inform any Certificateholder,
Lehman Brothers, Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated
inquiring by telephone of the information contained in the most recent Monthly
Report.

                                    -26-
<PAGE>
 
     Within a reasonable period of time after the end of each calendar year, the
Trustee shall furnish or cause to be furnished to each Person who at any time
during the calendar year was the Holder of a Senior Certificate a statement
containing the information with respect to interest accrued and principal paid
on such Holder's Certificates during such calendar year.  Such obligation of the
Trustee shall be deemed to have been satisfied to the extent that substantially
comparable information shall be provided by the Trustee pursuant to any
requirements of the Code as from time to time in force.

     (e)  Copies of all reports provided to the Trustee and the Administrator
for the Certificateholders shall also be provided to each Rating Agency and to
the Subordinated Certificateholders.

     (f)  In the event that any withholding tax is imposed on the Trust's
payment (or allocations of income) to a Certificate Owner, such tax shall reduce
the amount otherwise distributable to the Certificate Owner in accordance with
this Section.  The Trustee is hereby authorized and directed to retain from
amounts otherwise distributable to the Certificate Owners sufficient funds for
the payment of any tax that is legally owed by the Trust (but such authorization
shall not prevent the Trustee from contesting any such tax in appropriate
proceedings, and withholding payment of such tax, if permitted by law, pending
the outcome of such proceedings).  The amount of any withholding tax imposed
with respect to a Certificate Owner shall be treated as cash distributed to such
Certificate Owner at the time it is withheld by the Trust and remitted to the
appropriate taxing authority.  If there is a possibility that withholding tax is
payable with respect to a distribution (such as a distribution to a non-U.S.
Certificate Owner), the Trustee may in its sole discretion withhold such amounts
in accordance with this paragraph (f).  In the event that a Certificate Owner
wishes to apply for a refund of any such withholding tax, the Trustee shall
reasonably cooperate with such Certificate Owner in making such claim so long as
such Certificate Owner agrees to reimburse the Trustee for any out-of-pocket
expenses incurred.

Certificateholder of record on the preceding Record Date either by wire
transfer, in immediately available funds, to the account of such Holder at a
bank or other entity having appropriate facilities therefor, if such
Certificateholder shall have provided to the Certificate Registrar appropriate
written instructions at least five Business Days prior to such Distribution Date
and such Holder's Certificates in the aggregate evidence a denomination of not
less than $1,000,000 (or if such Certificateholder is a Depositor or an
Affiliate thereof), or, if not, by check mailed to such Certificateholder at the
address of such holder appearing in the Certificate Register.

filed such tax returns relating to the Trust (including a partnership
information return, Form 1065), and direct the Trustee to make such elections as
may from time to time be required or appropriate under any applicable state or
federal statute or rule or regulation thereunder so as to maintain the Trust's
characterization as a partnership for federal income tax purposes, (iv) collect
or cause to be collected any withholding tax as described in and in accordance
with Section 5.2(f) with respect to income or distributions to Certificate
Owners and (v) file or cause to be filed all documents required to be filed by
the Trust with the Commission and otherwise take or cause to be taken all such
actions as are notified by the Servicer to the Administrator as being required
for the Trust's compliance with all applicable provisions of state and federal
securities laws.

aggregate outstanding principal amount of the Senior Certificates plus all
accrued and unpaid interest thereon, plus all accrued and unpaid expenses of the
Trust.

Administrator at least 30 days but no more than 60 days prior to such redemption
date of their intention to cause redemption of the Senior Certificates.

     (c)  Within five Business Days of receipt of notice of final payment on the
Senior Certificates from the Administrator (whether pursuant to the exercise by
the Subordinated Certificateholders of their option contained in this Section
5.6, or pursuant to payment of the Senior Certificateholders, Principal
Distributable Amount pursuant to Section 5.2), the Trustee shall mail written

take appropriate steps, or may appoint an agent to take appropriate steps, to
contact the remaining Senior Certificateholders concerning surrender of their
Senior Certificates, and the cost thereof shall be paid out of the funds and

determination by the Trustee or is silent or is incomplete as to the course of
action that the Trustee is required to take with respect to a particular set of

     Section 9.2.  Rights upon an Event of Default.
                   ------------------------------- 

     (a)  If an Event of Default shall have occurred and be continuing, the
Trustee or Certificate Owners beneficially owning at least 25% in aggregate
outstanding principal amount of the Senior Certificates (subject to rescission
as described below) may declare by written notice to the Subordinated
Certificateholders (and the Trustee, if declared by the Certificate Owners), the
entire principal amount of the Senior Certificates immediately due and payable,
together with accrued interest thereon.  The Subordinated Certificateholders
shall have no right to declare an Event of Default or to make a declaration of
acceleration with respect to the Senior Certificates.

     At any time after such a declaration of acceleration with respect to the
Senior Certificates has been made and before a judgment or decree for payment of
the money due has been obtained by the Trustee, the holders of a majority in
aggregate principal amount of the Senior Certificates, by written notice to the
Subordinated Certificateholders and the Trustee, may rescind and annul such
declaration and its consequences if

            (i)   there has been deposited in the Certificate Account, either 
     pursuant to collections on the Trust Property or from amounts deposited
     with the Trustee by the Subordinated Certificateholders, an amount
     sufficient to pay

                  (A)  all accrued but unpaid interest on the Senior 
            Certificates, and

                  (B)  all sums paid or advanced by the Trustee and the

            expenses, disbursements and advances of the Trustee and the 
            Administrator and their agents.

     (b)  If the Senior Certificates have been declared due and payable
following an Event of Default, the Trustee may liquidate all or any portion of
the Trust Property, or may elect to maintain possession of the Trust Property
and continue to apply collections from the Trust Property as if there had been
no declaration of acceleration; provided, however, the Trustee will be
                                --------  -------                     
prohibited from selling the Trust Property following an Event of Default, unless

            (i)   the proceeds of such sale are sufficient to pay in full the 
     principal of and the accrued interest on the outstanding Senior
     Certificates at the time of such sale and all amounts required to be paid
     under Section 9.3(i) - (iv); or

            (ii)  the Trustee determines that the collections on the Trust 
     Property will not be sufficient on an ongoing basis to make all payments
     of interest on the Senior Certificates as such payments become due and to
     pay the

                                    -38-
<PAGE>
 
     outstanding principal amount of the Senior Certificates at maturity, and
     the Trustee obtains the consent of Certificate Owners beneficially owning
     66 2/3% of the aggregate outstanding amount of the Senior Certificates.

     Section 9.3.  Distributions.  If the Trustee collects any money or property
                   -------------

the following order:

            (i)   first, amounts due and owing and required to be distributed 
     to the Trustee pursuant to this Agreement;

            (ii)  second, amounts due and owing and required to be distributed
     to the Administrator pursuant to this Agreement and the Administration 
     Agreement;

            (iii) third, to the Senior Certificateholders, on a pro rata basis,
     an amount equal to the Senior Certificateholders' Interest Distributable 
     Amount;

            (iv)  fourth, to the Senior Certificateholders, on a pro rata 
     basis, the unpaid principal amount of the Senior Certificates; and

            (v)   fifth, any remaining money or property shall be distributed 
     to the Subordinated Certificateholders, according to their Percentage 
     Interests.

     The Trustee may fix a record date and payment date for any payment to the
Certificateholders pursuant to this Article IX.  At least 15 days prior to such
record date, the Trustee shall mail to each Certificateholder a notice that
states the record date, the payment date and the amount to be paid.

                    -----------------                                           
to Section 11.2 shall execute, acknowledge and deliver to the Subordinated
Certificateholders and to its predecessor Trustee an instrument accepting such
appointment under this Agreement, and thereupon the resignation or removal of
the predecessor Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become fully vested with all
the rights, powers, duties, and obligations of its predecessor under this
Agreement, with like effect as if originally named as Trustee.  The predecessor
Trustee shall deliver to the successor Trustee all documents and statements and
monies held by it under this Agreement; and the Subordinated Certificateholders
and the predecessor Trustee shall execute and deliver such instruments and do
such other things as may reasonably be required for fully and certainly vesting
and confirming in the successor Trustee all such rights, powers, duties, and
obligations.

     No successor Trustee shall accept appointment as provided in this Section
unless at the time of such acceptance such successor Trustee shall be eligible
pursuant to Section 11.1.

     Upon acceptance of appointment by a successor Trustee pursuant to this
Section, Finance I shall mail notice of the successor of such Trustee to all
Certificateholders and the Rating Agencies.  If Finance I shall fail 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 Finance I.

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 all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be eligible pursuant to Section 11.1, without the execution or
filing of any instrument or any further act on the part of any of the parties
hereto, anything herein to the contrary notwithstanding; provided further that
the Trustee shall mail notice of such merger or consolidation to the Rating
Agencies.

     Section 11.5.  Appointment of Co-Trustee or Separate Trustee.
                    ---------------------------------------------  
Notwithstanding any other provisions of this Agreement, at any time, for the
purpose of meeting any legal requirements of any jurisdiction in which any part
of the Trust Property may at the time be located, the Administrator 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 and Finance I
to act as co-trustee, jointly with the Trustee, or separate trustee or separate
trustees, of all or any part of the Trust Property, and to vest in such Person,
in such capacity, such title to the Trust, or any part thereof, and, subject to
the other provisions of this Section, such powers, duties, obligations, rights
and trusts as the Administrator and the Trustee may consider necessary or
desirable.  If the Administrator shall not have joined in such appointment
within 15 days after the receipt by it of a request so to do, the Trustee,
subject to the approval of Finance I, shall have the power to make such
appointment.  No co-trustee or separate trustee under this Agreement shall be
required to meet the terms of eligibility as a successor trustee pursuant to
Section 10.1 and no notice of the appointment of any co-trustee or separate
trustee shall be required pursuant to Section 11.1, except that notice of such
appointment shall be given to each Rating Agency.

     Each separate trustee and co-trustee shall, to the extent permitted by law,
be appointed and act subject to the following provisions and conditions:

            (i)   all rights, powers, duties, and obligations conferred or 
     imposed upon the Trustee shall be conferred upon and exercised or
     performed by the Trustee and such separate trustee or co-trustee jointly
     (it being understood that such separate trustee or co-trustee is not
     authorized to act separately without the Trustee joining in such act),
     except to the extent that under any law of any jurisdiction in which any
     particular act or acts are to be performed, 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 Property or any portion thereof in any such
     jurisdiction) shall be exercised and performed singly by such separate
     trustee or co-trustee, but solely at the direction of the Trustee;

            (ii)  no trustee under this Agreement shall be personally liable 
     by reason of any act or omission of any other trustee under this
     Agreement; and

            (iii) the Administrator and the Trustee acting jointly may at any 
     time accept the resignation of or remove any separate trustee or 
     co-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.  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,

                                    -43-
<PAGE>
 
either jointly with the Trustee or separately, as may be provided therein,
subject to all the provisions of this Agreement, specifically including every
provision of this Agreement relating to the conduct of, affecting the liability
of, or affording protection to, the Trustee.  Each such instrument shall be
filed with the Trustee and a copy thereof given to the Administrator and Finance
I.

     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.

Securitized Net Interest Margin Certificate (herein called a "Certificate")
issued by the Green Tree Securitized Net Interest Margin Trust 1994-A (the
"Trust").  The Trust was created pursuant to a Trust Agreement, dated as of
January 1, 1994 (the "Trust Agreement"), among Green Tree Manufactured Housing
Net Interest Margin Finance Corp. I ("Finance I"), Green Tree Manufactured
Housing Net Interest Margin Finance Corp. II ("Finance II") and Wilmington Trust
Company, not in its individual capacity but solely as Trustee (the "Trustee"), a
summary of certain of the pertinent provisions of which is set forth below.  To
the extent not otherwise defined herein, the capitalized terms used herein have
the meanings assigned to them in the Trust Agreement, each of the Assignments,
dated as of January 1, 1994 (the "Assignments") among (i) Green Tree and Finance
I and (ii) Green Tree, Finance I and Finance II, or the Transfer Agreement dated
as of January 1, 1994 (the "Transfer Agreement"), among Finance I, Finance II
and the Trust or the Servicing Agreement dated as of January 1, 1994 (the
"Servicing Agreement"), between the Trust and Green Tree, as servicer ("Green
Tree" or the "Servicer").

          The Trust, for value received, hereby promises to pay to CEDE & CO. or
registered assigns, the principal sum of $150M/150M/150M/58M, payable on or
before February 15, 2004.  The Trust will pay interest on this Certificate at
the rate per annum shown above on each Distribution Date until the principal of
this Certificate is paid or made available for payment, on the principal amount
outstanding on the preceding Distribution Date (after giving effect to all
payments of principal on the preceding Distribution Date), to the extent of the
Amount Available on each Distribution Date.

          This Certificate is one of the duly authorized Certificates designated
in the Trust Agreement as "Senior Certificates".  The Trust is also issuing
Subordinated Certificates (the "Subordinated Certificates").  This Certificate
is issued under and is subject to the terms, provisions and conditions of the
Trust

                                     B-2
<PAGE>
 
Agreement, to which Trust Agreement the holder of this Certificate by virtue of
the acceptance hereof assents and by which such holder is bound.  The
Certificates are payable solely from the assets of the Trust, which include (as
more fully described in the Trust Agreement) (i) a limited recourse note (the
"Finance I Note") issued by Finance I, and (ii) the residual interests in
certain trusts (the "Residual Assets").  The Finance I Note will be payable
solely from certain assets of Finance I (the "Fee Assets") acquired by Finance I
from Green Tree.

          Under the Trust Agreement, there will be distributed on the 15th day
of each month or, if such 15th day is not a Business Day, the next succeeding
Business Day (the "Distribution Date") (except that the first Distribution Date
will be March 25, 1994), to the person in whose name this Certificate is
registered at the close of business on the last day of the preceding calendar
month (the "Record Date"), such Certificateholder's Fractional Undivided
Interest in the sum of (a) the Senior Certificateholders' Interest Distributable
Amount and (b) the Senior Certificateholders' Principal Distributable Amount, to
the extent of the funds available therefor.

          The Trust shall pay interest on overdue installments of interest at
the Interest Rate to the extent lawful.

          As described above, the entire unpaid principal amount of this
Certificate shall be due and payable on or before the Distribution Date
occurring in February 2004.  Notwithstanding the foregoing, the entire unpaid
principal amount of the Certificates shall be due and payable on the date on
which an Event of Default shall have occurred and be continuing and the Trustee
or the Holders of the Certificates representing 25% of the Certificates have
declared the Certificates to be immediately due and payable in the manner
provided in Section 9.2 of the Trust Agreement.  All principal payments on the
Certificates shall be made pro rata to the Certificateholders entitled thereto.

          It is the intent and agreement of the Depositor, the Subordinated
Certificateholders and the Certificateholders that, for purposes of federal
income, state and local income and franchise and any other income taxes, the
Certificates will be treated as debt of the Trust.  Each Certificateholder, by
acceptance of a Certificate, covenants and agrees to treat, and to take no
action inconsistent with the treatment of, the Certificates as debt for such tax
purposes.

          Each Certificateholder, by its acceptance of a Certificate, covenants
and agrees that such Certificateholder will not at any time institute against
either  Subordinated Certificateholder or join in any institution against either
Subordinated Certificateholder of, any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceedings, or other proceedings under any United
States Federal or state bankruptcy or similar law in connection with any
obligations relating to the Certificates, the Trust Agreement or any of the
Related Documents.

          Except as provided in the Trust Agreement, distributions on this
Certificate will be made by the Trustee by check or money order mailed to the
Certificateholder of record in the Certificate Register without the presentation
or surrender of this Certificate or the making of any notation hereon, or by
wire transfer, in immediately available funds, to the account of such
Certificateholder at a bank or other entity having appropriate facilities
therefor, if such Certificateholder shall have provided to the Certificate
Registrar appropriate written instructions at least five Business Days prior to
such Distribution Date and such Certificateholder's Certificates in the
aggregate evidence a denomination of not less than $1,000,000 (or if such
Certificateholder is a Depositor or an Affiliate thereof).  Except as otherwise
provided in the Trust Agreement and notwithstanding the above, the final
distribution on this Certificate will be made after due notice by the Trustee of
the pendency of such distribution and only upon presentation and surrender of
this Certificate at the office or agency maintained for that purpose by the
Trustee.  The Record Date otherwise applicable to distributions shall not be
applicable to such final distribution.

          The Certificates do not represent an obligation of, or an interest in,
Green Tree, the Trustee or any Affiliate of any of them.  The Certificates are
limited in right of payment to certain collections and recoveries respecting the
Finance I Note and the Residual Assets, all as more specifically set forth in
the Trust Agreement.  None of the Trustee, the Administrator or the Subordinated
Certificateholders shall incur any personal liability in connection herewith.  A
copy of the Trust Agreement may, upon request, be examined by any
Certificateholder during normal business hours at the principal office of
Finance I and at such other places, if any, designated by Finance I.

          The Trust Agreement permits, with certain exceptions therein provided,
the amendment thereof and the modification of the rights and obligations of the
parties thereto and the rights of the Certificateholders under the Trust
Agreement at any time by the Subordinated Certificateholders and the Trustee.
In certain limited circumstances, the Trust Agreement may only be amended with
the consent of the Holders of Senior Certificates evidencing not less than a
majority of the aggregate outstanding principal amount of the Senior
Certificates and, in certain circumstances, 100% of the aggregate outstanding
principal amount of the Certificates.  Any such consent by the Holder of this
Certificate shall be conclusive and binding on such Holder and on all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in exchange herefor or in lieu hereof whether or not notation of such
consent is made upon this Certificate.

          As provided in the Trust Agreement and subject to certain limitations
set forth therein, the transfer of this Certificate is registrable in the
Certificate Registrar upon surrender of this Certificate for registration of
transfer at the offices or agencies of the Certificate Registrar maintained by
the First Trust National Association on behalf of the Trustee in St. Paul,
Minnesota, accompanied by a written instrument of transfer in form satisfactory
to the Trustee and the Certificate

                                     B-4
<PAGE>
 
Registrar duly executed by the holder hereof or such holder's attorney duly
authorized in writing, and thereupon one or more new Certificates of authorized
denominations evidencing the same aggregate fractional undivided interest in the
Trust of the same class shall be issued to the designated transferee.

          This Certificate may not be acquired by a "disqualified organization"
(as defined below).  By accepting and holding this Certificate, the Holder
hereof shall be deemed to have represented and warranted that it is not a
disqualified organization.  Any attempted or purported transfer in violation of
these transfer restrictions will be null and void and will vest no rights in any
purported transferee.  A "disqualified organization" means (i) the United
States, any State or political subdivision thereof, any foreign government, any
international organization, or any agency or instrumentality of the foregoing
(not including instrumentalities described in Section 168(h)(2)(D) of the Code
or the Federal Home Loan Mortgage Corporation), (ii) any organization (other
than a cooperative described in Section 521 of the Code) that is exempt from
federal income tax, unless it is subject to the tax imposed by Section 511 of
the Code or (iii) any organization described in Section 1381(a)(2)(C) of the
Code.

          The Senior Certificates are issuable only as registered Certificates
without coupons in denominations of $1,000 and integral multiples thereof.  As
provided in the Trust Agreement and subject to certain limitations therein set
forth, Senior Certificates are exchangeable for new Senior Certificates of
authorized denominations of a like aggregate fractional undivided 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 governmental charges payable in
connection therewith.

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

          The obligations and responsibilities created by the Trust Agreement
and the Trust created thereby shall terminate upon the payment to
Certificateholders of all amounts required to be paid to them pursuant to the
Trust Agreement and the disposition of all property held as part of the Trust.
Finance I and Finance II may at their option cause the Trust to prepay the
Senior Certificates in whole but not in part by contributing cash to the Trust
in an amount equal to the unpaid principal amount of the Senior Certificates
plus any accrued and unpaid interest, and such prepayment will effect early
retirement of the Senior Certificates; provided, however, such right of purchase
                                       --------  -------                        
is exercisable only as of a Distribution Date as of which the outstanding
principal amount of the Senior Certificates is less than 10% of the original
principal amount of the Senior Certificates.

                                     B-5

          The recitals contained herein shall be taken as the statements of the
Depositor or the Subordinated Certificateholders, as the case may be, and the
Trustee assumes no responsibility for the correctness thereof.  The Trustee
makes no representations as to the validity or sufficiency of this Certificate
or of the assignment of the Fee Assets or the Residual Assets or any related
document.

          Unless the certificate of authentication hereon shall have been
executed by an authorized officer of the Trustee, by manual or facsimile
signature, this Certificate shall not entitle the holder hereof to any benefit
under the Trust Agreement or be valid for any purpose.

          IN WITNESS WHEREOF, the Trustee on behalf of the Trust and not in its
individual capacity has caused this Certificate to be duly executed.

          THIS CERTIFIES THAT Green Tree Manufactured Housing Net Interest
Margin Finance Corp. I/Green Tree Net Interest Margin Finance Corp. II is the
registered owner of a nonassessable, fully-paid, fractional undivided interest
in the Green Tree Securitized Net Interest Margin Trust 1994-A (the "Trust").
The Trust was created pursuant to a Trust Agreement, dated as of January 1, 1994
(the "Trust Agreement"), among Green Tree Manufactured Housing Net Interest
Margin Finance Corp. I ("Finance I"), Green Tree Manufactured Housing Net
Interest Margin Finance Corp. II ("Finance II") and Wilmington Trust Company, as
Trustee (the "Trustee"), a summary of certain of the pertinent provisions of
which is set forth below.  To the extent not otherwise defined herein, the
capitalized terms used herein have the meanings assigned to them in the Trust
Agreement, each of the Assignments, dated as of January 1, 1994 (the
"Assignments"), between (i) Green Tree and Finance I and (ii) Green Tree,
Finance I and Finance II, or the Transfer Agreement, dated as of January 1, 1994
(the "Transfer Agreement"), among Finance I, Finance II and the Trust, or the
Servicing Agreement dated as of January 1, 1994 (the "Servicing Agreement"),
between the Trust and Green Tree, as servicer ("Green Tree" or the "Servicer").

          This Certificate is one of the duly authorized Certificates designated
in the Trust Agreement as "Subordinated Certificates" (herein called the
"Certificates").  The Trust is also issuing Senior Certificates (the "Senior
Certificates").  This Certificate is issued under and is subject to the terms,
provisions and conditions of the Trust Agreement, to which Trust Agreement the
holder of this Certificate by virtue of the acceptance hereof assents and by
which such holder is bound.  The Certificates are payable solely from the assets
of the Trust, which include (as more fully described in the Trust Agreement) (i)
a limited recourse note (the "Finance I Note") issued by Finance I, and (ii) the
residual interests in certain trusts (the "Residual Assets").  The Finance I
Note will be payable solely from certain assets of Finance I (the "Fee Assets")
acquired by Finance I from Green Tree.

                                     C-2
<PAGE>
 
          Under the Trust Agreement, no distributions of principal or interest
will be paid on the Subordinated Certificates until principal and interest on
the Senior Certificates have been paid in full (the "Senior Certificates Final
Payment").  On the Distribution Date following the Senior Certificates Final
Payment, there will be distributed on the 15th day of each month or, if such
15th day is not a Business Day, the next succeeding Business Day (the
"Distribution Date"), commencing on such Distribution Date, to the person in
whose name this Certificate is registered at the close of business on the last
day of the preceding Monthly Period (the "Record Date"), such Certificate-
holder's Fractional Undivided Interest in the amount in the Certificate 
Account, after payment of certain expenses of the Trust.

          It is the intent and agreement of the Depositor, the Subordinated
Certificateholders and the Senior Certificateholders that, for purposes of
federal income, state and local income and franchise and any other income taxes,
the Trust will be treated as a partnership and the Subordinated
Certificateholders will be treated as partners in that partnership and the
Senior Certificates will be treated as debt of the Trust.  The Subordinated
Certificateholders, by acceptance of a Certificate, agree to treat, and to take
no action inconsistent with the treatment of, the Certificates for such tax
purposes as partnership interests in the Trust.

          Except as provided in the Agreement, distributions on this Certificate
will be made by the Trustee by check or money order mailed to the Certificate-
holder of record in the Certificate Register without the presentation or
surrender of this Certificate or the making of any notation hereon.  Except
as otherwise provided in the Trust Agreement and notwithstanding the above, the
final distribution on this Certificate will be made after due notice by the
Trustee of the pendency of such distribution and only upon presentation and
surrender of this Certificate at the office or agency maintained for that
purpose by the Trustee.  The Record Date otherwise applicable to distributions
shall not be applicable to such final distribution.

          The Certificates do not represent an obligation of, or an interest in,
Green Tree, the Trustee or any Affiliate of any of them.  The Certificates are
limited in right of payment to certain collections and recoveries respecting the
Finance I Note and the Residual Assets, all as more specifically set forth in
the Trust Agreement.  None of the Trustee, the Administrator or the Subordinated
Certificateholders shall incur any personal liability in connection herewith.  A
copy of the Trust Agreement may, upon request, be examined by any Certificate-
holder during normal business hours at the principal office of Finance I and 
at such other places, if any, designated by Finance I.

          The Subordinated Certificates may not be acquired by (a) an employee
benefit plan (as defined in Section 3(3) of ERISA) that is subject to the
provisions of Title 1 of ERISA, (b) a plan described in Section 4975(e)(1) of
the Code or (c) any entity whose underlying assets include plan assets by reason
of a plan's investment in the entity (each, a "Benefit Plan").  By accepting and
holding this Certificate, the

                                     C-3
<PAGE>
 
Holder hereof shall be deemed to have represented and warranted that it is not a
Benefit Plan.

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

          The obligations and responsibilities created by the Trust Agreement
and Trust created thereby shall terminate upon the payment to Certificateholders
of all amounts required to be paid to them pursuant to the Agreement and the
disposition of all property held as part of the Trust.

          The recitals contained herein shall be taken as the statements of the

Trustee assumes no responsibility for the correctness thereof.  The Trustee
makes no representations as to the validity or sufficiency of this Certificate
or of the assignment of the Fee Assets or the Residual Assets or any related
document.

          Unless the certificate of authentication hereon shall have been
executed by an authorized officer of the Trustee, by manual signature, this
Certificate shall not entitle the holder hereof to any benefit under the Trust
Agreement or be valid for any purpose.

                            FEE ASSETS ASSIGNMENT

Tree.

     WHEREAS, pursuant to certain Pooling and Servicing Agreements or related 
agreements identified in Appendix I attached hereto, Green Tree or a 
subsidiary of Green Tree (which has assigned the rights to receive such fees 
to Green Tree) is entitled to receive certain guarantee fees, as specified in 
Appendix I hereto, (the "Guarantee Fees"), for providing credit enhancement 
against delinquencies, defaults and net liquidation losses on the related 
pools of manufactured housing contracts issued by or on behalf of Green Tree 
(the "Contracts").

     WHEREAS, pursuant to certain Pooling and Servicing Agreements identified in
Appendix II attached hereto (the "Pooling and Servicing Agreements"), Green Tree
is entitled to receive certain fees as specified in Appendix II hereto (the

Pursuant to such GNMA regulations, Green Tree is entitled to receive certain
servicing fees (the "GNMA Servicing Fees") for servicing the GNMA Pools.

     WHEREAS, pursuant to the terms and conditions set forth herein, Green Tree
desires to assign to Finance I its right to receive the Guarantee Fees, its
right to receive a portion of the Servicing Fees and its right to receive a
portion of the GNMA Servicing Fees.

transfers, assigns and delivers to Finance I its right to receive the portion of
the Servicing Fees payable after payment of the Normal Servicing Fee to Green
Tree, as further specified in Appendix II hereto (the "Excess Servicing Fees"),
payable on or after February 15, 1994.  Green Tree shall retain all rights to
receive late fees and extension fees paid by Obligors (as defined in the Pooling
and Servicing Agreements) as part of the Normal Servicing Fee.  In order to
effect such transfer, Green Tree shall deliver to the Trustee of each
Securitized Pool a written notification in substantially the form attached
hereto as Exhibit A.

     1.03  GNMA Excess Spread.  Subject to and upon the terms and conditions set
           ------------------                                                   
forth in this Agreement, Green Tree, as a contribution of capital, hereby
transfers, assigns and delivers to Finance I its right to receive the GNMA
Excess Spread as defined herein, payable on or after February 15, 1994.  The
"GNMA Excess Spread" payable each month shall be that portion of the GNMA
Servicing Fee payable to Green Tree with respect to each GNMA Pool, after
payment to Green Tree of (i) the FHA insurance premiums paid by Green Tree with
respect to FHA-insured Contracts, (ii) an amount equal to .50% per annum,
payable monthly, of the outstanding balance of such GNMA Pool, (iii) the amount
of prepayment shortfalls paid by Green Tree with respect to the prior month, and
(iv) all liquidation losses paid by Green Tree upon payment of a FHA or VA
claim, or final denial of such claim, during the prior month.  In order to
effect such transfer, Green Tree shall deliver to the Custodian holding the
Custodial Account on behalf of GNMA with respect to the GNMA Pools a written
notification in substantially the form attached hereto as Exhibit B.

     1.04  Security Interest in the Fee Assets.  Although the parties intend
           -----------------------------------                              
that the assignment of Green Tree's right to receive the Guarantee Fees, Excess
Servicing Fees and GNMA Excess Spread pursuant to this Agreement shall
constitute an absolute assignment and not a loan, if such assignments are deemed
to be a loan, the parties intend that the rights and obligations of the parties
to such loan shall be established pursuant to the terms of this Agreement.  The
parties also intend and agree that Green Tree shall be deemed to have granted to
Finance I, and Green Tree does hereby grant to Finance I, a perfected first-
priority security interest in the items designated in Sections 1.01 through 1.03
above, and that this Agreement shall constitute a security agreement under
applicable law.  Green Tree further agrees that it shall at any time or times
hereafter execute such instruments and perform such acts as the Trustee or
Finance I may request to establish and maintain a valid security interest in the
items designated in Sections 1.01 through 1.03 above.

           ---------------------------                                          
respect to each Contract which is refinanced by an Obligor (as defined in the
Pooling and Servicing Agreements) through Green Tree, Green Tree agrees to pay
to or upon the order of Finance I an amount (an "inside refinancing payment")
equal to the unpaid balance of such Contract, multiplied by the factor

occurs and the Securitized Pool or GNMA Pool in which such Contract was
included, as specified in Exhibit C attached hereto. Green Tree further agrees
that any such inside refinancing payments that it is obligated to pay
hereunder during any one month period will be made by 3:00 Central Standard

pursuant to its right as Servicer to repurchase such Contract in a Securitized
Pool when the outstanding balance of such Securitized Pool has declined to 10%
or less of its initial principal balance, or which is repurchased by Green Tree
because of a breach of certain representations and warranties contained in the
applicable Pooling and Servicing Agreement or GNMA Guaranty Agreement, Green
Tree agrees to pay to or upon the order of Finance I an amount (a "repurchase
payment") equal to the unpaid balance of such Contract multiplied by the factor
applicable to such Contract, based on the month in which such repurchase occurs
and the Securitized Pool in which such Contract was included, as specified in
Exhibit C attached hereto.  Green Tree further agrees that any such repurchase
payments that it is obligated to pay hereunder during any one month period will
be made by 3:00 Central Standard Time on the business day immediately preceding

           ---------------------                                          
servicer of the Contracts, to provide such reports with respect to the Fee
Assets as Finance I may reasonably request, and to enter into such further
agreements with Finance I or its assignee relating to such servicing obligations
as Finance I may reasonably request.

Ladies and Gentlemen:

     You are Custodian of a Custodial Account with respect to certain pools of
manufactured housing contracts formed by Green Tree Financial Corporation
("Green Tree") and securing GNMA Certificates, as listed by pool number on
Appendix I attached hereto (the "GNMA Pools").  As such Custodian, it is your
duty to remit to Green Tree the servicing fees payable in accordance with the
regulations of GNMA (the "GNMA Servicing Fees").  We hereby notify you that we
have assigned the GNMA Excess Spread with respect to such GNMA Pools (as defined
below) to Green Tree Manufactured Housing Net Interest Margin Finance Corp. I
("Finance I"), effective February 15, 1994.  From that date forward you should
remit the GNMA Excess Spread to Finance I or its assignee.

     The GNMA Excess Spread payable each month to Finance I or its assignee
shall equal that portion remaining of the GNMA Servicing Fees with respect to
each GNMA Pool, after payment to Green Tree of the following (i) the FHA
insurance premiums paid by Green Tree with respect to FHA-insured Contracts,
(ii) an amount equal to .50% per annum, payable monthly, of the outstanding
balance of such GNMA Pool, (iii) the amount of prepayment shortfalls paid by
Green Tree with respect to the prior month, and (iv) all liquidation losses paid
by Green Tree upon payment of an FHA or VA claim during the prior month.  Each
month, as Custodian, you will receive from Green Tree, in addition to the
monthly report prepared by Green Tree with respect to such GNMA Pools, a
statement setting forth such amounts and setting forth the amount of the GNMA
Excess Spread to be remitted to Finance I or its assignee.

                         ASSIGNMENT OF RESIDUAL ASSETS

     1.01  Residual Assets.  Subject to and upon the terms and conditions set
           ---------------                                                   
forth in this Agreement, Green Tree, as a contribution of capital, hereby
transfers, assigns and delivers to each of Finance I and Finance II its right,
title and interest in fifty percent (50%) of each of the Residual Assets,
effective February 15, 1994 (or the record date with respect to the
distributions made on February 15, 1994, as necessary).  In order to effect such
transfer, Green Tree shall deliver to or upon the order of Finance I and Finance
II the certificates evidencing such Residual Assets, duly endorsed by Green
Tree.

     1.02  Security Interest in Residual Assets.  Although the parties intend
           ------------------------------------                             
that the assignment of the Residual Assets pursuant to this Agreement shall
constitute an absolute assignment and not a loan, if such assignments are
deemed to be a loan, the parties intend that the rights and obligations of the
parties to such loan shall be established pursuant to the terms of this
Agreement. The parties also intend and agree that Green Tree shall be deemed
to have granted to the Trustee, and Green Tree does hereby grant to the
Trustee, a perfected first-priority security interest in the items designated
in Section 1.01 above, and that this Agreement shall constitute a security
agreement under applicable law. If the trust created by the Trust Agreement
terminates prior to the satisfaction of the claims of any person under any
Senior Certificates (as defined in the Trust Agreement), the security interest
<PAGE>
 
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.

     2.01  Inside Refinancing Payments.  As part of the foregoing transfer,
           ---------------------------                                       
with respect to each Contract which is refinanced by an Obligor (as defined in
the Pooling and Servicing Agreements) through Green Tree, Green Tree agrees to
pay to or upon the order of Finance I and Finance II an amount (an "inside
refinancing payment") equal to the unpaid balance of such Contract, multiplied
by the factor applicable to such Contract, based on the month in which such
refinancing occurs and the Securitized Pool in which such Contract was included,
as specified in Exhibit C to the Fee Assets Assignment; provided, however, that
                                                        ------------------     
if an inside refinancing payment with respect to the same Contract is paid by
Green Tree in connection with the assignment by Green Tree of the Fee Assets
pursuant to the Fee Assets Assignment, such inside refinancing payment shall not
be paid in connection with the assignment of the Residual Assets hereunder.
Green Tree further agrees that any such inside refinancing payments that it is
obligated to pay hereunder during any one month period will be made by 3:00
Central Standard Time on the business day immediately preceding the Distribution
Date for such month.

     2.02  Repurchase Payments.  As part of the foregoing transfer, with respect
           -------------------                                                  
to each Contract in a Securitized Pool which is repurchased by Green Tree
pursuant to its right as Servicer to repurchase such Contract in such
Securitized Pool when the outstanding balance of such Securitized Pool has
declined to 10% or less of its initial principal balance, or which is
repurchased by Green Tree because of a breach of certain representations and
warranties contained in the applicable Pooling and Servicing Agreement, Green
Tree agrees to pay to or upon the order of Finance I or Finance II an amount (a
"repurchase payment") equal to the unpaid balance of such Contract, multiplied
by the factor applicable to such Contract, based on the month in which such
repurchase occurs and the Securitized Pool in which such Contract was included,
as specified in Exhibit C to the Fee Assets Assignment; provided, however, that
                                                        ------------------     
if a repurchase payment with respect to the same Contract is paid by Green Tree
in connection with the assignment by Green Tree of the Fee Assets pursuant to
the Fee Assets Assignment, such repurchase payment shall not be paid in
connection with the assignment of the Residual Assets hereunder.  Green Tree
further agrees that any such repurchase payments that it is obligated to pay
hereunder during any one month period will be made by 3:00 Central Standard Time
on the business day immediately preceding the Distribution Date for such month.

servicer of the Contracts, to provide such reports with respect to the Residual
Assets as Finance I or Finance II may reasonably request, and to enter into such
further agreements with Finance I or Finance II or their assignee relating to
such servicing obligations as Finance I and Finance II may reasonably request.

     WHEREAS, pursuant to a Residual Assets Assignment, dated as of January 1,

capitalized terms used herein and not otherwise defined have the meanings 
assigned to them in the Residual Assets Assignment.)

     WHEREAS, pursuant to the terms and conditions set forth herein, Finance I
and Finance II desire to transfer the Residual Assets to the Trust.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth in this Agreement, and for other good and valuable consideration, the

forth in this Agreement, Finance I and Finance II, as a contribution of capital,
hereby transfer, assign and deliver to the Trust their right, title and interest

Ladies and Gentlemen:

     You are Custodian of a Custodial Account with respect to certain pools of
manufactured housing contracts formed by Green Tree Financial Corporation
("Green Tree") and securing GNMA Certificates, as listed by pool number on
Appendix I attached hereto (the "GNMA Pools").  As such Custodian, it is your
duty to remit to Green Tree's assignee, Green Tree Manufactured Housing Net

the regulations of GNMA (the "GNMA Servicing Fees").  We hereby notify you that
we have pledged the GNMA Excess Spread with respect to such GNMA Pools (as
defined below) to Green Tree Securitized Net Interest Margin Trust 1994-A (the
"Trust"), effective February 15, 1994.  From that date forward you should remit
the GNMA Excess Spread to the Trust.

     The GNMA Excess Spread payable each month to the Trust shall equal that
portion remaining of the GNMA Servicing Fees with respect to each GNMA Pool,
after payment to Green Tree of the following (i) the FHA insurance premiums paid
by Green Tree with respect to FHA-insured Contracts, (ii) an amount equal to
.50% per annum, payable monthly, of the outstanding balance of such GNMA Pool,
(iii) the amount of prepayment shortfalls paid by Green Tree with respect to the
prior month, and (iv) all liquidation losses paid by Green Tree upon payment of
an FHA or VA claim during the prior month.  Each month, as Custodian, you will
receive from Green Tree, in addition to the monthly report prepared by Green
Tree with respect to such GNMA Pools, a statement setting forth such amounts and
setting forth the amount of the GNMA Excess Spread to be remitted to Finance I
or its assignee.
